        Despite its innovative and avant-garde reputation, the luxury industry initially began showing a very low commitment to new online marketing tools and it held a conservative approach to selling when compared to other sectors. Nowadays, the context has dramatically changed and luxury brands are approaching with an increasing interest social networks as well as the online selling. This research aims to clarify the current strategic approaches of the players in the different luxury markets towards the social commerce phenomenon, from both a theoretical and an empirical point of view. The purpose is to test a framework that can be used to classify luxury companies’ strategies regarding social media adoptions based on actual theories on social media. Four strategies related to the social media adoption by luxury brands have been identified: the Social brand ambassadors strategy class (low promotional content percentage and low social commerce score) includes those brands that use social media for entertainment and user engagement; the Social showcases strategy (high promotional content percentage and low social commerce score) includes those brands that use their social accounts as online catalogues; the Social infotainers strategy (low promotional content percentage and high social commerce score) includes those brands that scored high in social commerce, mainly because of the provision of informative content and brand–consumer interactions, but they were linked to more entertainment-oriented actions rather than product-related ones. Finally, the Social sellers strategy (high promotional content percentage and high social commerce score) includes those brands that have integrated social commerce into their online strategies and have subsequently exploited the potential of social media to drive online and offline sales. The database is built using original data from a content analysis of 100 luxury brands’ postings on five different social media platforms – namely Facebook, Twitter, YouTube, Instagram, and Pinterest. The total final sample included 12,132 Facebook posts, 21,216 tweets on Twitter, 1,105 YouTube videos, 10,138 Instagram pictures/videos, and 117,359 Pinterest pictures. The main findings are the following: luxury brands adopt at this stage the Social brand ambassadors and Social showcases approaches; brands belonging to the perfumery, cosmetics, jewelry and watches markets show a more developed attitude towards the social commerce; in other luxury markets, such as wine and spirits, brands still adopt a Social Brand Ambassador strategy, while managers should increase the promotional content in order develop the social commerce. The Fashion & Accessories brands show a positive relationship between the percentage of promotional content and social commerce score. This means that social commerce adoptions depend on the single brand’s strategic choices, ranging from low adoption to best practices. In general, social commerce is still not widespread; many luxury fashion brands, while presenting new collections during fashion weeks, focused on fashion shows, backstage events, and celebrities, rather than really promoting the new product lines with materials, availability, and purchasing indications. This social media approach is mainly focused on increasing brand awareness rather than increasing social commerce. If managers aim at increasing social commerce they should add direct call to action and link the contents to e-commerce market place. Automotive brands are concentrated in the Social showcases area; This sector encounters natural limitations in the introduction of social commerce due to the difficulty of selling products through the digital channel; many brands have, however, devised strategies to approach their users during the purchasing process prior to the actual transaction to take advantage of the increasing ROPO phenomenon. Conversely, the Perfumes & Cosmetics sector shows a highly fragmented approach to social commerce. The content analysis based on single post contents has shown that actually the contents are based on pictures of the products, or the brand, information on events, and a large and increasing presence of video posts based storytelling about the history of the product and the brand heritage; the most social commerce oriented posts are picture or video focused on the product. The commercial contents that aim at developing the see now, buy now approach are mainly based on video shows.

        Recent research has pointed out the emergence of new online actors, especially in the domain of fashion and lifestyle—“social media influencers” or SMIs (Etter, Colleoni, Illia, Meggiorin, & D’Eugenio, forthcoming). SMIs are defined as “people who possess greater than average potential to influence others due to such attributes as frequency of communication, personal persuasiveness or size of—and centrality to—a social network.” As SMIs become professionals, with a mass audience of followers, they gain competence in generating sophisticated content such as creation of stories, videos, visuals, etc. (McQuarrie, Miller, & Phillips, 2013). As such, SMIs are tempted to leverage their online influence to partner with brands. One of the reasons brands collaborate with SMIs is that they are considered trustworthy and “one of the few forms of real, authentic communication” (Scott, 2015, p. 295). Authenticity is recognized in the marketing literature as an important attribute, as consumers increasingly desire authenticity in their products and brands (Chronis & Hampton, 2008). A notion of authenticity which has been gaining acceptance revolves around whether an individual or brand expresses their true self (Moulard, Raggio, & Folse, 2016). Holt (2002, p. 83) notes, “To be authentic, brands must be disinterested; they must be perceived as invented and disseminated by parties without an instrumental economic agenda, by people who are intrinsically motivated by their inherent value”. However, collaborating with brands may question SMIs authenticity as their inner desires to focus on products they are passionate about are challenged by commercial opportunities to showcase brands that they would not ordinary like. Their credibility might be questioned as the persuasive effect of their messages is often attributed to their perceived noncommercial nature as compared to branded advertisements. Despite growing research on influencers and acknowledged pressure of pursuing financial gains (Abidin & Ots, 2015), past research has overlooked the challenges to remain authentic when collaborating with brands. As such, our research focuses on the question: what are the strategies of SMIs to maintain authenticity while they are under commercial pressure? To answer it, we conducted a research in the context of fashion, beauty and lifestyle, as it is one of the most successful and visible domains of digital production. We analyze posts from 49 influencers participating in 9 brand campaigns that employed multiple SMIs simultaneously. These observations are complemented with 27 interviews with SMIs to understand “behind the scene” goals pursued to project this authenticity. Results suggest that SMIs implement two potentially complementary strategies expressing authenticity under commercial pressure: 1) passionate authenticity, which refers to one’s expressing of his/her inner self and being passionate even when involved in a collaboration, and 2) informational authenticity, which refers to being consistent with the facts and not lying about the partnership, the influencer or the products promoted. From a theoretical standpoint, the notion of passionate authenticity has been established in the previous literature (Moulard, et al., 2016), but we identify a new form of authenticity that we name informational authenticity. It thus extends the literature and builds on previous research to reframe the concept of authenticity (Grayson & Martinec, 2004; Morhart, Malär, Guevremont, Girardin, & Grohmann, 2015; Napoli, Dickinson, Beverland, & Farrelly, 2014). From a managerial standpoint, our findings should help SMIs manage their authenticity under threat as it suggest that they can either use Passion or Information. SMIs should be cautious to report the reality of the partnership and the product in their WOMM contents. Similarly, they should keep producing noncommercial messages about brands they are really passionate about. In the same vein, managers should be attentive to let SMIs select products in order to increase enthusiasm for the brand and minimize constraints to give room for personalized communication aligned with SMI’s style and opinions.

        This paper aims to examine the effect of live streaming, recently adopted by online clothing sellers to help sell clothes on the Facebook. Drawing on the literature in retailing, adoption behavior, and e-commerce, this paper proposes the framework to test the effect on customers’ perceived values, trust, and engagement intention. When shopping online, consumers are generally concerned with legitimacy of the vendor and authenticity of products or services (Chen and Dhillon 2002). Live streaming allows shoppers to view the seller’s face and expressions, background (e.g. clothes, furniture), as well as offered products that are not pre-recorded or edited prior to being presented in the online store. Due to the spontaneous, interactive nature of live streaming, viewers ask questions and receive answers from the page in almost real time (Wang et al. 2000), and the seller can use the feedback to respond to the need of customers better. Live streaming is expected to positively affect on customer’s perceived utilitarian value (authenticity, responsiveness). By merely viewing the seller showing, wearing, or putting different clothes on a mannequin can be fun and enjoyable like viewing the fashion show. Live streaming is expected to positively affect on customer’s perceived hedonic value (enjoyment). The act of shopping can also provide a symbolic benefit, as customers express their personal values, identity, self through the shopping experience (Chandon et al., 2000). Given that live streaming is not prevalent and used by general users, customers who participate in the live streaming may be perceived that they are innovative. Live streaming by possibly affecting customer hedonic, utilitarian, and symbolic value would be likely to positively affect trust and engagement intention. Trust can refer to the extent to which customers believe the web site is legal, ethical and credible and can protect their privacy(Wan, 2000). Trust can lead to positive feelings towards the online seller, and in turn can increase intention to revisit and purchase from the site (Chiu et al. 2009). Engaged people are generally those visiting the site frequently, spend substantial time on the site, and have many page views (Calder, Malthouse, and Schaedel 2009). The relationship of live streaming, and perceived values (customer hedonic, utilitarian, and symbolic value), trust, and engagement intention will be tested by conducting the survey with about 400 online shoppers. The data will be analyzed using the structural equation modeling. Results are expected to provide implications for the use of live streaming for online shopping. The study aims to examine the process underlying the effects of livestreaming on consumer trust and engagement. Livestreaming has potentials to bridge the gap between traditional and online shopping, allowing sellers and shoppers distant in space to interact and smoothening the online shopping experiences.

        Food has become a significant lifestyle and life quality generator, and consumers are increasingly developing food regimes with expectations of healthier, happier selves. The global food industry has turned to delivering towards these expectations, and functional foods form a significant multimillion dollar growth category. Fortified with added health-giving compounds, these foods are promoted as the modern, convenient way of obtaining health benefits from food intake itself, rather than from the use of vitamin supplements (Grunert, 2013). However, there are indications that their appeal and usage varies considerably across nations. Somewhat surprisingly, few studies have considered functional food consumption through a culturally mediated lens, as consumption entities used to convey and transfer meaning. This research explores personal meaning making for one such proposed functional food concept. Foods which are fortified to enable greater control over hunger control are currently under development as potentially assisting those seeking weight loss. The data consisted of 14 in-depth phenomenological interviews with New Zealand women who were attempting weight loss. Participants discussed their lived food and weight loss experiences and then freely responded to the weight loss foods concept. The findings reveal the omnipresent nature of weight loss practices in daily lives, with the perception of success, or failure, sometimes underpinning one’s sense of self. As found by Willis & Knobloch-Westerwick (2014), motivations for weight loss were dominated by appearance and body image concerns, driven by the continuation of persistent societal expectations privileging thinness. Extending this, the present research found a conflation of motivations where slimness was seen to equate to healthiness. A line of progression in the types of practices was revealed where many ‘fad diets’ were attempted with typically unsuccessful long term results. Although, healthism was internalised as an overriding way of thinking about food and weight loss practices, paradoxically, this often co-existed with the desire for foods of indulgence, especially for those identifying as emotional eaters. Vastly different dispositions were revealed towards the proposed innovation of the fortified weight loss foods. These were interpreted as being aligned with perceptions of identity (Tajfel & Turner, 1986). Whilst the overall fortification of foods was viewed negatively, risks and doubts were mitigated in some cases in the interest of trying the proposed foods. The research findings resonated with societal contradictions observed for food consumption (Warde 1997), and paradoxes specifically theorised for technology (Mick & Fournier, 1998). Although, technology has been theorised to be a positive enabler in consumers’ lives, offering feelings of freedom, competence, and control, it can also be regarded as an intrusion, leading to feelings of enslavement and incompetence (Mick & Fournier, 1998). Whilst there was the promise of enhanced health and wellness from a bio-technological innovation, this contradicted central beliefs about what it means to be healthy, where food for many consumers represents values of naturalness, purity, nostalgia, and simplicity (Barsky, 1988; Biltekoff, 2010). Implications of the research for functional foods marketers are outlined, advocating the need for continuing understanding of the paradoxical aspects of consumption in contemporary health contexts.

        Given the recent modest growth of the personal luxury good market and the urge to face difficulties through innovative brands’ marketing communication strategies, this paper examines the potentialities of tactical associations between luxury fashion brands and furniture design. Results indicate that there can be positive repercussions deriving from luxury fashion brands and furniture design interconnections. In particular, associations with collectable furniture design may help to define and enhance brands’ luxury values whilst providing consumers with innovative and creative luxury brand experiences. Future expectations in this market show a compound annual rate (CAGR) of 3% to 4% through 2020, to just about €280 billion. This is dramatically slower than the past fast growth experienced from the mid-1990s to the late 2000s. In this scenario, luxury fashion managers and marketers must envision new strategies to succeed and surpass competition. In order to be competitive and successful, luxury brand managers must take into account current market dynamics and find pertinent and substantial solutions. This paper shifts its attention to the identification of how in such a difficult scenario different cultural industries can meet in order to mutually enhance their circuits of value. Some studies have demonstrated that in order to meet such new global challenges, luxury fashion firms may discover strategic opportunities in art (Codignola, 2016). Given their symbolic connotation and aesthetic value, high-end furniture design items are more and more perceived as art works exchanged in art auctions or fairs, collected and purchased by collectors, exhibited in galleries or museums. At the same time, furniture design goods show some divergences from conventional art works (i.e. functionality, reproducibility, etc.) and some correspondences with fashion goods. By observing the luxury fashion sector, one may then find--for different sets of reasons--more than one interesting intersection with the furniture design sector. By taking into account the furniture design sector within its specific market features and goods, this paper argues that through furniture design LFBs can develop engaging creative and innovative brands’ marketing communication strategies. Compared to art, such strategies would be able to add value and strengthen LFBs’ luxury features even in a more effective way.

        The willingness to actively contribute to more sustainability bares important challenges for managers who must take strategic decisions. The literature about corporate social responsibility has developed in many directions, with often a divide in focus, between society (Acquier & Aggeri, 2015) or corporate sustainability and responsibility (Bansal & Song, 2017). The paper sits at the intersection of these fields by focusing on the question of ethical dilemmas. The objective is to approach the question of ethics in context, through the trade-offs that managers are facing when taking strategic decisions to build sustainable business models, to discuss the contours of the ethical competences at work. The paper focuses on a specific context, the one of successful pure players of sustainability in the luxury fashion industry. It means first that we leave aside the question of organizational change to analyze the core dilemmas that even new actors that start from scratch must face. These pure players could also be named “social entrepreneurs” (Elkington & Hartigan, 2008) or “elegant disrupters” (Bendell & Thomas, 2013). Second, by focusing on luxury fashion we locate our analysis in an industry where the nature of the activity is both a source of salient controversies and of exemplary practices (Kapferer, 2010; Godart & Seong, 2014), two aspects that have the potential to make visible some dilemmas. We focus on a small number of cases of organizations that we selected per criteria of similarities and differences, to allow for an inductive in-depth comparative case study (Yin, 2009). The four organizations are: a producer of yak products, a fur recycling company, a fur auction house and a digital platform for emerging designers. The cases are similar in that each organization is a successful promoter of sustainable practices. The four cases however differ in that each puts at the core of the business model different types of sustainability issues and is based at a different level of the value chain (sourcing, fabrication, intermediation and market access). Also, the four organizations differ in the degree to which they aim to disrupt existing practices in the luxury fashion industry. Data were collected through a series of interviews and complementary press articles, websites and reports. Data analysis proceeds in two steps. We start by narrating each case through the voice of the organization, to describe and understand the rationale behind each business model. We then further our interpretation of the cases through a comparative analysis by systematically recording the tensions or contradictions. Each firm organizes the activity around key engaging choices that promote sustainability but do not lift some inbuilt dilemmas–labelled as: sustainability vs. luxury fashion, sustainability vs. sustainability, and sustainability today vs. tomorrow. The paper highlights how innovative players can openly discuss some dilemmas, approaching sustainability as a story they care about but also as a debate. Yet, the paper also points to the fact that some dilemmas may remain harder to reflect upon, especially the ones that can counter in the long-run the objectives that were at the base of the business. Some questions as the one of growth, in time and scale, might push far the reflexive ability but it is also where ethical competences might be the most needed.

        The New Product Development (NPD) in the textile industry is peculiar, as it follows constraints that are particular to the fashion business. A qualitative study comprising 45 interviews were conducted in a South American textile industry and results showcase that fashion forecast, pressure for newness, and cost reduction are relevant matters. Introduction The textile industry follows a particular cycle for New Product Development (NPD) as it answers the demand from the fashion industry. Fashion supply chain is fragmented, as the production process is fragmented with companies playing different roles in the production cycle. There are companies that uses the raw material to produce yarns that will be transformed into fabrics, which then it is transformed into clothes, through process that may be a single sewing to complex process that demands intermediate process such as industrial washes. These clothes are sold to consumers through various selling channels, such as stores, retailers, e-commerce, and even door-to-door. Usually one company plays only one of these roles in the supply chain, what makes the production plan to be fragmented amongst several different companies in the supply chain (Şen, 2008). After globalization, this supply chain became even more complex as each chain may be located in different parts of the world, due to production costs and optimization. This scenario results in a supply chain that demands several planning skills, that works, sometimes, with extensive production cycles. (Thomassey, 2014). But, as Christopher, Lowson, & Peck (2004) noted, the supply chain in the fashion business must be agile to respond to changes in demand from consumers, which often occurs, and it can be also very complex as clothing is a way for consumers to either differentiate or fit in society, and the rules to be in or out of society patterns changes fast (Cholachatpinyo, Fletcher, Padgett, & Crocker, 2002a, 2002b). Due to this complexity and richness of information, the production cycle in fashion business has been extensively studied in the literature (Alexander & Contreras, 2016; Aung & Sha, 2016; Oxborrow & Brindley, 2014) but authors often use a wide perspective to grasp an overview of the supply chain they are studying, using market data and information, or gathering general information from companies that are present in the fashion supply chain. Authors focused their analysis in the supply chain itself, and we could not find studies that focused on the perspective of the product development task in the challenging context of fashion business. There are some characteristics from the fashion business that differentiate New Product Development (NPD) from a classical Business to Business (B2B) scenario. In a brief description of the fashion business production system, we see that it starts with the production of raw materials that varies from natural fibers (e.g. cotton, silk, linen) or artificial fibers (e.g. polyester, nylon, elastane) that are then spinning into threads that may contain one or more different fibers. These threads are then transformed into fabrics through several different weaving techniques, and then it may go through some finishing treatments (e.g. dying, washing), and then it goes to garment manufacturing where garment makers produce clothes for their own brands or for third-parties brands. These clothes are then sold to consumers through various channels (e.g. retail stores, electronic stores). If we analyze this brief description we can see that fashion may influence in all parts of the production cycle, including the demand for raw materials: if denim products are in vogue, then there is a growing demand for cotton products, if sportswear is in vogue, then the demand improves for artificial fibers, and so on. One other thing that should be noted is that usually each part of the production cycle is performed by a different company: the most common scenario we see in the textile industry includes companies that produce only threads, and sell these threads to textile companies that produce fabrics to sell to garment makers that produces clothes to sell to brands to sell them to consumers. There are some companies that integrates two or more parts of the production cycles but they are the exception, not the rule. This fragmented production process combined with the fashion influence result in long production cycles: a designer’s idea may take from three to eighteen months to be available to consumers, depending on the production channels assessed by the designer. These characteristics showcase how NPD in the fashion business may be complex and therefore it should be investigated further in the literature, and this is the objective of this study. In order to do that, we researched the specific literature in NPD that is vastly discussed in literature as it is responsible for creating, managing and releasing products that are both appealing to customers and profitable to the company. (Brown & Eisenhardt, 1995). Understanding what makes an NP succeed in the market has been on the marketing agenda for a long time, including the fashion business (Alexander & Contreras, 2016; Clarke, 2012; Thompson & Haytko, 1997). One interesting point of view is to understand the predecessors of NP success in the market. Henard & Szymanski (2001) conducted a meta-analysis of 60 studies focused on the antecedents of NP success and proposed a list of 24 predictors of NP performance, which they grouped into four categories: (i) product characteristics, (ii) firm strategy characteristics, (iii) firm process characteristics and (iv) marketplace characteristics. We selected the most relevant predecessors discussed by Henard & Szymanski (2001) and Song & Xie (2000) to use as a basis for a script for interviews with NPD professionals. Methodology We conducted in-depth interviews with 45 professionals from different areas that participate in, or are impacted by, NPD process in a South American textile industry. From now on we will call this company “Southex”. These interviews offered a deep understanding of the perspective of NPD professionals, both insiders (professional that work in the NPD team) or outsiders (professional from departments that work as an internal supplier or client for the NPD team). Southex is one of the biggest textile producers in the world, with producing units in Latin America, commercial offices in Europe, Asia, and America. Sales are over U$ 1 bi/year, and the company employed more than 8,000 people in 2012, when this study was performed. Their main market is Latin America where fashion seasons are in opposition to the ones in the North part of the globe, home of the fashion trendsetters for global macro trends (Europe, USA, and Japan). This leads to a one-year postponement of fashion trends, so when something is released as a fashion trend for summer in Europe, it will be considered a trend for summer one year later in Latin America. Southex NPD team had 12 exclusively dedicated professionals as of 2012. Southex launches products in the market with the concept of collections, when the company releases a group of NPs in the market. Every year, the company releases two collections in the market. It usually takes up to six months for NPD team to complete and launch a new collection. Research into fashion trends, commercial needs and technological improvements available in the market are the main sources the company uses to develop NP. Prior to launching a product in the market, the NPD team needs to test its production process in order to guarantee that the product can be produced on a large scale at competitive costs. Every collection is launched as a sample of fabrics that will be produced 4-6 months in the future. If a collection is released in January, the products that Southex is launching will start to be produced in June. So their clients, mainly garment makers and fashion brands, need to coordinate their production chain to start receiving these fabrics after June. Considering the production cycle in these garment makers, it is estimated that the clothing produced with the fabric launched by Southex in January will be delivered to retail stores (and then available to the consumer) in November, almost one year after Southex has launched the fabric in the market. In order to gather a deep perspective of all matters related to NPD we interview 45 professionals, totaling over 1,600 hours of recorded interviews. 12 insiders, comprising 100% of the team available at that moment, and 33 outsiders from departments such as Marketing, Sales, and Technical Support. Their positions ranged from analysts to directors.. All interviews followed a predefined script of topics. Interviews were transcribed and sent to the corresponding professional for validation, during which they could ask for adjustments. 12 professionals asked for changes in the transcription and we used the changed and approved text, together with the 33 unchanged texts in this analysis. Results and Discussion All texts were then codified according to content, which involved identifying similar topics and applying codes to facilitate analysis of the interviews. Using the predecessors of NP success has facilitated our understanding of the matters related to NPD at Southex. By formatting the presentation of information gathered in the interviews with the predecessors we were able to see the main issues found in NPD. In total, there were 421 mentions codified. After analyzing the codification of the interviews, we can see that Cross function is the main topic addressed by respondents. This is due to the relationship that the flow of NPD activities in the company. As we can see, there were several issues related to the relationship of NP team with the outsiders and that communication amongst insiders and outsiders needs to be improved. There are some context-specific content that appeared as relevant in the analysis of these interviews: insiders are worried with the pressure they feel to forecast fashion preference for products. They say that fashion industry is constantly demanding new technologies, new products, and this has been creating a pressure to accelerate product development they think it is not healthy to the system. Also there is a general worry (insiders and outsiders) with the pressure for price reduction in basic products. Some products are considered basic and are included for several collections (interviewees mentioned that some products are included in more than 15 successive collections) and for these products instead of demanding for innovation, there is a demand for price reduction which leads outsiders to perform tests to substitute materials or changes in the production to reduce costs without prior knowledge from NPD team, which causes several problems in the organization. It is important to point out that even though we used only one company in this study, it was a complete and deep perspective, as we were able to collect high quality data with all 45 professionals that are directly or indirectly related to NPD in the company. Also, as Southex works as a thread and fabric producer, it showed us an insider perspective about the textile supply chain in the fashion business. Even though the exploratory study presented the reality of a firm in an extensive and very detailed way, it may not reflect the full complexity of other organizations in the market; thus, caution is advised if applied in a market that differs deeply from the scenario presented in this study. However, it is also important to remember that this is a qualitative approach where generalization is not expected, and the attention for details is important.

        The choice of strain, substrate, and environmental conditions are fundamental factors that determine the ability of a fungus to develop and produce mushrooms with high quality. The objective of this study was to compare the strains of Lentinula edodes and Ganoderma lucidum originated from South Korea and Brazil in relation to their vegetative development in different culture media, to obtain isolates with high quality. The strains of the two mushroom species from Brazil and South Korea grew slowly, possibly because of abiotic factors or storage technique used. However, it may be concluded that temperature, humidity, light, pH, and nutrients from the substrate, if not regulated appropriately may affect the vegetative species.

        The aim of this plan was the creation of a series of forests landscape within the forest-damaged areas in Janggye Neighborhood Park (132,000㎡), located in Jangsu-gun, Jeollabuk-do, for improving the quality of rural landscape and promoting leisure activities. Additional objectives included developing forest-related local festivals and energizing the local economy. In establishing these plans, the researcher considered analyses of the following designating the project areas: forests, types of forest landscape damage, views, landscape quality, and topographical characteristics. Local residents were given survey questions, and 58 sets of response sheets were incorporated into the construction plans for the forest landscape. The goal of the plan was established as the construction of specialized forests that offer outstanding landscape quality and healing effects. The selected trees were the Acer palmatum Thunb. (beautiful foliage), Chamaecyparis obtusa (outstanding healing effects), and Koelreuteria paniculata Laxm. (related festival applicability). The Acer palmatum Thunb. forest design reflects consideration for the highlighting of seasonal landscape changes and wintertime outdoor ambulation; thus, its location is planned along the trail in linear. Considerations for the Chamaecyparis obtusa forest were visitor accessibility and distribution of phytoncide; hence, placement is mostly in the valley near existing park facilities, with trees placed in rows for user convenience. For visual impact, the Koelreuteria paniculata Laxm. forest must be seen from nearby highways; thus, it was allocated to the higher elevation sites within forest-damaged areas using natural-looking patterns of planting. Local festivals featuring the Chamaecyparis obtusa and Koelreuteria paniculata Laxm. forests as themes were planned. Such programs were envisioned as contributing to revitalization of rural economy.

        This study analyzed the use suitability with regard to resource characteristics of provincial parks to provide basic data for park management, and has yielded the following results. Organized by resource, the use suitability is highest for landscape/scenery, weather/climate, smell/sound/colors, and topography/ geology. By season, weather/climate is important in the spring, and landscape/scenery is important in the summer and autumn in determining the use suitability. Aside from the temporary phenomena of the weather/climate, the resource that most influences the use suitability of provincial parks is landscape/scenery for spring, summer, and autumn. Specifically, on a park basis, Mt. Moak’s most important resource for park use suitability is the weather/climate; other parks’ most important resource is landscape/scenery. Mt. Moak and Mt. Seonun Provincial Parks have high use suitabilities in the spring; Mt. Daedun and Mt. Mai Provincial Parks have high use suitabilities in the spring and summer. Organizing parks on a seasonal basis, there are differences depending on the resource type; moreover, there are differences in use suitability between parks depending on the season. Through evaluating the use suitability of parks, it is possible to identify resource characteristics of parks and to predict the seasonal use frequency of parks in park management, which can be used as the basic data for determining the intensity of management. As such, this study can aid visitors in determining which park suits their use purposes, and for managers in determining the priority by which the parks should be managed.

        This present contribution examines by means of a discrete event and agent-based simulation the potential of a joint use of resources in the installation phase of offshore wind energy. To this end, wind farm projects to be installed simultaneously are being examined, the impact of weather restrictions on the processes of loading, transport and installation are also taken into consideration, and both the wind farm specific resource allocation and the approach of a resource pool or resource sharing, respectively, are being implemented. This study is motivated by the large number of wind farms that will be installed in the future and by the potential savings that might be realized through resource sharing. While, so far, the main driver of the resource sharing approach has been the end consumer market, it has been applied in more and more areas, even in relatively conservative industries such as logistics. After the presentation of the backgrounds and of the underlying methodology, and the description of the prior art in this context, the network of the offshore wind energy installation phase will be described. This is the basis for the subsequent determination of the savings potential of a shared resource utilization, which is determined by the performance indicators such as the total installation time and degree of utilization of the resources. The results of the simulation show that weather restrictions have a significant effect on the installation times and the usage times of the resources as well as on their degree of utilization. In addition, the resource sharing approach, has been identified to have significant savings potential for the offshore wind energy installation.

        Due to the existence of uncertainties and the unknown time variant environmental disturbances for ship course nonlinear control system, the ship course adaptive neural network robust course-keeping controller is designed by combining the backstepping technique. The neural networks (NNs) are employed for the compensating of the nonlinear term of the nonlinear ship course-keeping control system. The designed adaptive laws are designed to estimate the weights of NNs and the bounds of unknown environmental disturbances. The first order commander are introduced to solve the problem of repeating differential operations in the traditional backstepping design method, which let the designed controller easier to implement in navigation practice and structure simplicity. Theoretically, it indicates that the proposed controller can track the setting course in arbitrary expected accuracy, while keeping all control signals in the ship course control closed-loop system are uniformly ultimately bounded. Finally, the training ship of Dalian Maritime University is taken for example; simulation results illustrated the effectiveness and the robustness of the proposed controller.

        Dyes are widely used in various industries including textile, cosmetic, paper, plastics, rubber, and coating, and their discharge into waterways causes serious environmental and health problems. Four different carbon nanostructures, graphene oxide, oxidized multi-walled carbon nanotubes, activated carbon and multi-walled carbon nanotubes, were used as adsorbents for the removal of Nile Blue A (NBA) dye from aqueous solution. The four carbon nanostructures were characterized by scanning electron microscope and X-ray diffractometer. The effects of various parameters were investigated. Kinetic adsorption data were analyzed using the first-order model and the pseudo-second-order model. The regression results showed that the adsorption kinetics were more accurately represented by the pseudo-second-order model. The equilibrium data for the aqueous solutions were fitted to Langmuir and Freundlich isotherms, and the equilibrium adsorption of NBA was best described by the Langmuir isotherm model. This is the first research on the removal of dye using four carbon nanostructures adsorbents.

        This paper introduces a nitrogen-doped ordered mesoporous carbon (NOMC) derived from glucosamine with hybrid capacitive behaviors, achieved by successfully combining electrical double-layer capacitance with pseudo-capacitance behaviors. The nitrogen doping content of the fabricated NOMC reached 7.4 at% while its specific surface area (SBET) and total pore volume reached 778 m2 g−1 and 1.17 cm3 g−1, respectively. A dual mesoporous structure with small mesopores centered at 3.6 nm and large mesopores centered at 9.9 nm was observed. The specific capacitance of the reported materials reached up to 328 F g−1, which was 2.1 times higher than that of pristine CMK-3. The capacitance retention rate was found to be higher than 87.9% after 1000 charge/discharge cycles. The supplementary pseudocapacitance as well as the enhanced wettability and conductivity due to the incorporation of nitrogen heteroatoms within the carbon matrixes were found to be responsible for the excellent capacitive performance of the reported NOMC materials.

        Ganglioside GT1b, glycosphigolipids with three sialic acid, is known to play an important role in signal transduction such as epidermal growth factor receptor (EGFR). EGF is also known to induce resumption of meiosis and cumulus cells expansion during porcine oocyte maturation. Therefore, this study was conducted to evaluate the effects of ganglioside GT1b on resumption of meiosis and cumulus cells expansion in porcine oocyte maturation. First, porcine cumulus-oocyte complexes were cultured in NCSU-23 medium supplemented with GT1b (0, 1, 2 and 4 μM) at 44 h. We observed that the proportion of the metaphase II (M II) stage was significantly increased in the 2 μM GT1b (78.0 ± 2.3) treated group than in the other groups. Furthermore, expression of cumulus cells expansion factor genes (Has2, TNFAIP6, Ptx3) were significantly increased in the 2 μM GT1b treated group than in the other groups. Next, we investigated the meiotic maturation and the expressions of cumulus cells expansion factor genes after GT1b and/or EGF treatment. The proportion of the M II stage was significantly higher in the GT1b+EGF (90.1 ± 2.3) treated group than in the other groups. Moreover, expressions of cumulus cells expansion factor genes were significantly increased in the GT1b+EGF treated group than in the control group. After in vitro fertilization, fertilization rate, preimplantation development competence and quality of blastocyst were improved in oocytes derived from GT1b+EGF treated group. Taken together, these results suggest that exogenous ganglioside GT1b improving the developmental competence of porcine embryos via increase of resumption of meiosis and cumulus cells expansion during in vitro maturation of porcine oocytes.

        With increasing interests on health issues, whole grains are getting focus with their various beneficial effects along with unique characteristics. Studies on whole grains, however, are mostly focused on whole wheat grains, no systematic researches on whole rice grain has been attempted. In this study, we tried to characterize the starches in whole rice grain including morphology, molecular weight distribution and its side chain structures for further application. Early harvested whole rice grains, named as green whole rice (GWR) was coarsely grounded and starch fraction was separated through alkaline steeping method and dried for the analysis. Morphology of starch particles of GWR was investigated with scanning electron microscopy (SEM) and no significant differences was observed compared to the control rice starches. Pre-treatments such as dehulling and steaming also did not affect overall shape of starches in rice. Molecular weight distribution of GWR starch was analyzed with gel permeation chromatography (GPC) and compared with normal rice starch. GPC analyses revealed that the relative ratio of higher molecular weight fractions in GWR was significantly higher than normal rice. In addition, side chain structures of amylopectin molecules in GWR starch was analyzed with high performance size exclusion chromatography (HPSEC). The average number of DP in GWR was shorter with higher ratio of shorter side chain fractions than normal rice starch. These findings on GWR starch would be useful basement for following research and application of green whole rice.

        Cryptography is a science to maintain the security of the message by changing data or information into a different form, so the message cannot be recognized. Today, many algorithms have been proposed for image encryption, but the chaotic encryption methods have a good combination of speed and high security. In recent years, the chaos based cryptographic algorithms have suggested some new and efficient ways to develop secure image encryption techniques. The chaos-based encryption schemes are composed of two steps: chaotic confusion and pixel diffusion. In the chaotic confusion stage, a combination of the chaotic maps is used to realize the confusion of all pixels. In this paper, we first give a brief introduction into chaotic image encryption and then we investigate some important properties and behaviour of the logistic map. The logistic map, aperiodic trajectory, or random-like fluctuation, could not be obtained with some choice of initial condition. Therefore, a noisy logistic map with an additive system noise is introduced. The proposed scheme is based on the extended map of the Clifford strange attractor, where each dimension has a specific role in the encryption process. Two dimensions are used for pixel permutation and the third dimension is used for pixel diffusion. In order to optimize the Clifford encryption system we increase the space key by using the noisy logistic map and a novel encryption scheme based on the Clifford attractor and the noisy logistic map for secure transfer images is proposed. This algorithm consists of two parts: the noisy logistic map shuffle of the pixel position and the pixel value. We use times for shuffling the pixel position and value then we generate the new pixel position and value by the Clifford system. To illustrate the efficiency of the proposed scheme, various types of security analysis are tested. It can be concluded that the proposed image encryption system is a suitable choice for practical applications.
