The relationship between virus, vector insect and its host plant has been studied in epidemic of virus disease, fitnessof vector insect, symbiosis and phylogenesis of the relationship, etc. The biological association, symbiosis, concept hasbeen suggested on the virus-vector relationship since 2000. We have conducted such a typical study with the Rice stripevirus and the small brown planthopper, Laodelphax striatellus. In addition, it is able to extend our view to ecosystemservice of the relationship. We reviewed the trophic efficiency included with virus factor. Nutrient loss of the host plantby virus is negative effect but terrestrial decomposition by the virus may be positive feedback in ecosystem. Thus, thevirus-vector relationship is able to be understand not only as competition for the host plant’s nutrition but also as indirectmutualism for the efficient utilization of the host plant or fitness to environmental conditions, especially climate change.

The Protocol for China’s accession into the WTO stipulated certain differential treatment for China, including the determination of normal value in anti-dumping investigations for the transitional period of 15 years. This treatment was authorized by the Protocol in response to concerns raised by other WTO Members at the time of China’s entry into the WTO. Since the transitional period is over in November 2016, there is an argument supporting the grant of market economy status to China, although the Protocol does not require the automatic grant of market economy after the passage of the transitional period. However, China’s recent trade measures, which have been adopted to press another WTO Member to meet its political objective, raise a question as to whether China is indeed ready for market economy status. This article analyzes such case and offers a view on the grant of market economy status to China.

consumption, has been attempted to replace with sharing economy which is consumer-to-consumer’s activity of obtaining, giving, or sharing the access to goods and services (Hamari et al., 2016). Research argued that the sharing economy develops based on information and communication technology (ICT) as it is an emerging economic-technological phenomenon, proliferation of using social networking site (SNS) (e.g. Instagram, Facebook, YouTube), and increased consumer awareness (Belk, 2014; Hamari et al., 2016). SNS refers to a digital environment that allows individual to create his/her space where sharing and constructing relationship with others are possible (Lin & Lu, 2011). Among the numbers of SNSs, Instagram is gaining notable attention as powerful marketing tool which may especially be important for fashion industry. Hutchins (2017) reported that number of its daily active users exceeds 400 million, and 90% of users are under 35 who may be familiar with the idea of the sharing economy. In terms of marketing, 53% of Instagram users are found to follow their favorite brands (Hutchins. 2017). According to Ryan and Deci (2000), consumer behavior of using information technology such as Instagram was influenced by extrinsic and intrinsic motivations. Although numerous researches have done with the sharing economy and SNS respectively, despite the recognized role of SNS in the sharing economy, comprehensive and empirical study of the sharing economy and SNS is very limited. Hence, the purpose of this research is to investigate consumer’s motivations to use Instagram for participating sharing economy by developing research framework based on the motivation theory (Ryan & Deci, 2000) perspective.

This study searches the welfare function of social economy and examines whether it can be the alternative of the welfare state or not. To do this, we set up 5 common variables of social economy and the welfare state, and compared them for finding their similarities and differences. Common variables compose of background, domain, pursuing value, welfare realization method, and welfare delivery system. The results show that even though they are different among each other, social economy performs welfare functions like the welfare state, but the role of it should be identified as a complementary one instead of the welfare state.

Ocean economy plays a crucial role in the strengthening maritime safety industry and in the welfare of human beings. Electric Submersible Pumps (ESP) have been widely used in floating platforms on the sea to provide oil for machines. However, the ESP fault may lead to ocean environment pollution, on the other hand, a timely fault diagnosis of ESP can improve the ocean economy. In order to meet the strict regulations of the ocean economy and environmental protection, the fault diagnosis of ESP system has become more and more popular in many countries. The vibration mechanical models of typical faults have been able to successfully diagnose the faults of ESP. And different types of sensors are used to monitor the vibration signal for the signal analysis and fault diagnosis in the ESP system. Meanwhile, physical sensors would increase the fault diagnosis challenge. Nowadays, the method of neural network for the fault diagnosis of ESP has been applied widely, which can diagnose the fault of an electric pump accurately based on the large database. To reduce the number of sensors and to avoid the large database, in this paper, algorithms are designed based on feature extraction to diagnose the fault of the ESP system. Simulation results show that the algorithms can achieve the prospective objectives superbly.

economic growth and revenue / profit expansion, we will end up with overconsumption and wastes, bringing serious damage to our planet (Kotler, 2015). He advocated the transition from the growth-oriented economy to the steady-state economy. This research explores marketing in such steady-state economy. Researchers have put efforts in developing theories in related concepts such as social marketing (e.g., Kotler & Zaltman, 1971) and corporate social responsibility (CSR; see Peloza & Shang, 2011 for a review). Inoue and Kent (2014) developed a conceptual framework that explains antecedents and consequences of corporate social marketing. However, their research, as well as those on CSR, has not addressed marketing in steady-state economy. Thus, we attempt to fill this research gap by developing propositions. We conducted multiple case studies (Eisenhardt, 1989; Yin 2014). Based on theoretical sampling, three firms were selected from different industries (food, alcohol, and furniture) with different technologies, located in different areas in Japan (Tokyo, Nagano, and Kagoshima). We collected primary and secondary data, and conducted interviews. In spite of the differences, the three firms run business similarly. First, they pursue a sustainable growth and not a rapid growth. Second, doing what is good for society is a part of their business goal and not CSR. Finally, they choose inefficiency than lowering the product quality.economy are developed: P1. Selling high quality products at profitable but reasonable price enhances firm’s credibility, which in turn improves the probability of firm’s long-term survival. P2. Limiting distribution channel allows firm to avoid price competition and set reasonable pricing, which in turn improves the probability of firm’s long-term survival. P3. Marketing mix of high quality product, reasonable pricing, and limited distribution channel generates positive word-of-mouth, allowing firm to save promotion costs. P4. Prosocial behavior in procurement increases the brand loyalty, which in turn improves the probability of firm’s long-term survival. P5. Portfolio of business-to-business and business-to-consumers businesses allows stable management and building strong brand. Further research is needed to develop these propositions into hypotheses and empirically test them with large samples. The authors hope that this research will be the first step for “steadiness-oriented marketing.”

The growing pace of market globalization has enabled firms to find it increasingly attractive to exploit growth opportunities abroad. To this end, predicting firms’ success and growth in foreign markets has become an important issue to international business researchers and managers. The international business literature suggests that different internal firm and foreign market specific environment factors drive internationalization of firms including firms’ structure, strategy, orientations, capabilities and nature of foreign market competition. Researchers interested in the field of international entrepreneurship have also given attention to firms’ international entrepreneurial orientation (IEO) as a potential driver of firms’ internationalization behavior, with few recent studies reporting investigations into the relationship between IEO and internationalization scope. The entrepreneurship literature suggests that variations in entrepreneurial behaviors may lead to exploitation of “new entry” (Oviatt & McDougall, 2005; Cavusgil & Knight, 2015). Within the international entrepreneurship discipline, international new entry is construed to entail identification and exploitation of new product-market opportunities abroad, or a pursuit of internationalization scope (Dai et al., 2014). Internationalization scope is defined as the process of seeking new market opportunities across multiple foreign markets, and is operationalized variously with indicators that tap the percentage of overseas revenue to total revenue, and the number of foreign countries and geographic regions from which a firm receives its sales. Thus, internationalization scope is viewed to be inherent and essential to the exhibition of an IEO, and may be driven by firms’ entrepreneurial proclivity. While a few studies have looked at how IEO impacts percentage of revenue firms obtain from foreign markets (Dai et al., 2014), little studies have studied how and when IEO drives regional expansion. This is notwithstanding the fact that traditional internationalization theory points to regional expansion as an antecedent to global expansion. Indeed, international business scholars have argued that a combination of increasing informal exporting activities, rising liberalization of regional economies, colonial bias, regional economic blocs and the emergence of middle class in many regional markets has created opportunities for firms to internationalize within neighboring geographical regions. Additionally, it has been argued that the benefits and costs of regional protection can motivate firms to pursue regionalization strategy as an antecedent or an alternative to globalization strategy. In drawing insights from earlier works, therefore, the present study focuses on the regional expansion of exporting firms in a Sub-Sahara African economy – Ghana, and examines how international entrepreneurial-oriented behaviors drive the firms’ intra-Africa expansion. African markets are noted for their diversity in national laws, cultures, geography, and infrastructural development. Particularly relevant to internationalizing African firms is the diversity and imperfection of marketing channels across African markets. An important implication for African firms, therefore, is how they can leverage their comparative advantage of handling diversity and imperfection of marketing channels in their home African market to successfully compete in overseas host markets with similar conditions. Accordingly, we further empirically examine how a firm’s ability to manage heterogeneous and imperfect marketing channels moderates the effect of IEO behaviors on regional expansion. We posit that the extent to which firms develop managerial and organizational capabilities to successfully compete in conditions of high market channel diversity and imperfection is a major contingency factor that can help explain when entrepreneurial behaviors influence regional expansion. By empirically examining these questions, this study brings new insights to IEO research by showing that IEO behaviors are differentially related to regionalization strategy depending on firms’ capability to manage heterogeneous and imperfect regional marketing channels. Specifically, findings from our study of small and medium sized firms in Ghana doing business in regional African markets show that regional expansion increases when levels of product innovation intensity, competitive aggressiveness and autonomous behavior are high and when regional channel management capability increases in magnitude. Additionally, the study provides evidence to show that increases in risking-taking behavior decrease regional expansion when regional channel management capability is high. Furthermore, the study demonstrates that although product innovation novelty and proactiveness are directly related to regional expansion their effects are cancelled out when levels of regional channel management capability are high.

Because of environmental pollution and lack of resources, necessity of energy efficiency improvement and reduction of exhaust gas emission and CO2 have grown in importance. Therefore a lot of studies are conducted for HEV(hybrid electric vehicle) and PHEV(plug-in hybrid electric vehicle). In addition, automobile companies are researching and manufacturing HEV and PHEV. Due to cost and time problem, simulation is preferred than experimental test to find better component size for efficiency improvement. In this research, backward simulation program is developed base on Dynamic Programming. Using this simulation program, fuel economy sensitivities for each parameter are analyzed and compared. Fuel economy is measured for a combined cycle that is calculated from FTP-75 and HWFET cycle. The target parameters are front/rear power train efficiency, drag coefficient, vehicle mass, rolling resistance coefficient, tire radius, center of gravity. The most sensitive parameter is front power train efficiency and second is drag coefficient. Rear power train efficiency, vehicle mass, rolling resistance coefficient are third, forth and fifth. By comparing sensitivities, we can choose a better way to improve fuel economy of HEV.

이 논문에서는 CGE모형을 통해 온실가스 감축정책이 제주지역 농업 및 총생산에 미치는 영향을 계측 하였다. 분석결과 탄소세를 부과할 경우에는 전라권의 GRDP가 2.522% 감소하는 것으로 나타났고, 제 주권은 0.272% 감소하는 것으로 분석되었다. 배출권거래제의 경우 제주권의 GRDP 감소효과는 0.01% 로 나타났다. 산업부문별 산출효과를 분석하면 전력이 1.411% 감소하고, 화학제품 1.370% 감소하여 그 업종의 산출액이 각각 18억원과 9억원 정도 줄어드는 것으로 분석되었다. 또한 에너지다소비산업인 건 설, 운수·보관업, 일반기계, 금속제품 등의 산출이 감소하는 것으로 나타났다. 또한 배출권거래제를 도 입할 경우 탄소세 부과보다 산출 감소가 크게 줄어드는 것으로 분석되었다. 이는 배출권거래를 통해 온 실가스 규제의 영향을 최소화할 수 있기 때문인 것으로 파악된다.

The major complaint of hybrid vehicle driver is that real fuel economy is lower than the certified fuel economy. Therefore, it is important to analyze the cause of low fuel economy and to improve the fuel consumption at real driving condition. In this study, the various speed profile is measured by driving urban road with considering different traffic jam. By using backward simulation, the fuel economy characteristics of the acquired driving modes are analyzed. From the simulation results, the operating points of engine and motor analyzed and the cause of decrease of real fuel economy is examined.

복지국가는 국민의 행복과 삶의 질 개선을 추구하는 것을 사명으로 하는 국가이다. 이 논문은 복지국가를 민주(주의)국가의 연장선상인 ‘후기민주국가’로 간주하고 복지국가로서의 한국의 현실을 제도화 진전의 측면에서 점검하고자 하며, 이러한 제도화의 진전은 정치적 과정과 경제 논리의 교차지점에서 살펴보려 한다. 한국의 국가는 지속적인 경제적 성장을 이룩하고 민주주의 제도와 과정을 도입함으로써 대내외적으로 명실상부한 자본주의 민주국가로서 복지체계의 측면에서는 기본적인 틀과 구색은 갖추게 됐다. 그러나 정부의 사회정책은 여전히 미흡하다. 정부는 경제성장에 걸맞게 국민의 욕구를 충족하기에 충분한 재원을 마련할 만큼의 강력한 사회정책을 채택하려 하지 않았으며, 정부의 사회정책의 효과도 크게 미흡했다는 것은 국제적인 비교를 통해서도 확인할 수 있다. 현재의 복지체계는 전반적인 개혁이 필요하지만, 복지 수준 자체가 낮기 때문에 이를 개선하기 위한 복지 재정의 확대 개편이 필요하다. 복지재정 확대는 반드시 사회적 협의가 필요한 사항이며 이를 위한 협의와 논쟁의 비용은 국민의 복지국가에 대한 인식의 확산과 사회 단위 간의 민주적인 절차를 거칠 때 최소로 줄일 수 있을 것이다.

본 연구는 최근 논의가 활발히 진행되고 있는 한국의 사회적경제에 대한 연구동향을 살펴보고 향후 사회적경제에 관한 실증적인 연구를 위한 시사점을 제안하는 것을 목적으로 하고 있다. 사회적경제에 관련한 기존연구들의 내용분석을 통해 사회적경제의 학문적 접근의 변화를 점검하고 우리나라에 적합한 사회적경제에 나아갈 방향성에 대한 논의의 장 마련과 함께 실증적 연구의 필요성을 제언하고자 한다.

박근혜정부의 창조경제는 국민을 창조활동의 주인공으로 자리매김함으로써 기존의 전문가 중심, 과학기술공급중심의 경제사회발전전략과는 다른 특성을 보여주고 있으나 그 해석과 정책 실행에 있어 그 특징을 찾아보기 어렵다. 본 연구는 창조경제가 주목한 국민의 창의성이 과학기술자의 창의성과 무엇이 다르며, 그것이 정책 패러다임으로서 어떤 의미를 갖는지 광범위한 문헌 연구를 통해 밝힘으로써 창조경제가 담아내야 할 도전과 과제를 제시하는 것을 목적으로 한다. 국민은 사용자로서의 창의성에 더불어 인문학적, 철학적, 윤리적, 경험적 능력을 바탕으로 한 생활인/삶의 주체로서의 창의성을 갖고 있으며 이것은 과학기술자의 창의성과는 구분되는 고유의 창의성이라 할 수 있다. 사용자로서의 창의성, 생활인/삶의 주체로서의 창의성의 발현은 삶의 가치에 대한 선택을 내포하며 이는 소비행태의 변화, 삶의 방식의 변화를 통해 기술 고착, 사용자 고착을 타파함으로써 시스템 혁신을 이루거나 새로운 사회ㆍ기술시스템의 구성 혹은 전환을 촉진할 수 있다. 이런 맥락에서 국민의 창의성은 기존의 전문가/과학기술공급중심 혁신 패러다임이 아닌 사용자/현장중심 혁신 패러다임’의 토대로서 역할 할 수 있다. 따라서 국민의 창의성에 주목하고 있는 창조경제는 사용자/현장 중심 혁신 패러다임의 실현이라는 새로운 경제사회발전정책과제를 안고 있다고 할 수 있다.

Introduction Over the past 30 years, Chinese textile and clothing manufacturers have successfully established themselves as leading original equipment manufacturers (OEMs) for world markets. This reputable position requires dedicated cost management; however, incremental increases in labor, land prices, rent, and production costs in China threaten and may eventually eliminate their OEM advantage (Yam, Lo, Sun, & Tang, 2003). The worldwide economic and business recession has intensified cost cutting measures as the essential survival tool for maintaining competitiveness. Since the mid-1990s, many Chinese companies have begun to recognize the importance of developing their own global brands and moving up the value-creation ladder (Fan, 2006). One such company is Aimer Group, Ltd., a vertically integrated premium underwear manufacturer. Initially founded in 1993 as an OEM, Aimer quickly transitioned to establish its own brands in domestic markets and, in recent years, has ventured into international markets. Currently, Aimer and its umbrella product lines are among the most recognized underwear brands in China with a manufacturing capacity of 10 million pieces. Their merchandise includes an array of women’s, men’s, teen girl’s and children’s lines as well as custom-made lingerie. According to the Chinese General Chamber of Commerce, Aimer Group has maintained the highest market share and the largest sales volume in the underwear sector for several years in China’s markets (Aimer, 2011). Objectives The purpose of the study was to investigate the design strategies implemented by Aimer to support their successful branding efforts. Specifically, the researchers seek to find: (a) the core elements in Aimer’s design strategies; (b) Aimer designers’ approach to product development; and (c) How design strategies support Aimer’s overall branding and marketing strategies. Findings will provide valuable implications for other Chinese apparel manufacturers who strive to integrate design innovation in order to remain competitive. Research Method A case study method was implemented which included: on-site visits to Aimer Group’s headquarters, manufacturing facility, and retail stores in Beijing; in-depth interviews with Aimer Groups’ Chairman, senior management, Chief Design Officer, designers, retail store managers, and the general manger of the Beijing manufacturing facility; and a review of the company website and other internal documents, as well as an extensive external search of relevant news reports, social media contents, industry information, and academic literature. A qualitative data analysis method was utilized. Findings Aimer brands have grown and matured along with the Chinese consumers. Until the late 1990s, consumers passively accepted whatever the industry provided for them. Today, 15 years later, consumers have become keenly aware of what they want in underwear and that desire drives the industry’s new product development. Aimer’s design strategies are consumer-centric but also a reflection of its internal strategic direction. Its core elements include the following: (1) Understanding consumer lifestyles: Extensive fashion industry trend analysis, consumer research, and market/sale feedback are just starting points for product development at Aimer. In addition, they use broader consumer lifestyle analysis, including an examination of new technology trends, consumer preferences for jewelry, cosmetics, car and cell phone designs, popular video/computer games, consumers’ financial management behaviors, and societal hot topics as a way of guiding product design. (2) Innovation: Innovation is of paramount importance in Aimer’s product development. They have maintained active partnerships with international suppliers and Research & Development teams to ensure the latest fiber discoveries, fabric developments, and pattern engineering technology are incorporated into new product design. (3) Tradition preserved and reinvented: Aimer brands keep certain essential elements integral to their overall style, reinventing and integrating heritage elements into new designs. By doing so, brand history is enriched and continuity sustained. Aspers (2010) suggests that product development must embrace contextual knowledge: the designer’s general knowledge of fashion and their lifeworld. Each domain is used to interpret fashion. A designer’s lifeworld comprises their inherent values and beliefs, presenting challenges when creating products for consumers who live in different lifeworld. Aimer’s solutions to the challenge include the following: (1) Designers as entrepreneurs: Designers are trained to be entrepreneurs who must think of design not only from creative aspects but also within a business context. The company has established effective protocols for new product design and adoption procedures and standards; meanwhile, designers are provided with weekly sales records as market feedback to guide their future design directions. They are also given opportunities on a regular basis to travel to various international and domestic markets to gain first-hand experience and knowledge of fashion trends and consumers. (2) Teamwork: Designers from various regions of China and internationally are grouped in teams and assigned to work together on brands. This provides ample opportunity for them to interact and learn from each other so that their lifeworld is expanded. Branding literature suggests that consumer’s individual and shared brand experiences affect a consumer-brand relationship (Chang, Long, Chieng, & Hua, 2006) which is of critical importance to brand loyalty. Aimer’s design strategies support its branding and marketing strategies by: (a) contributing to consumers’ positive, consistent, and multi-dimensional brand knowledge as a part of the brand-leveraging process (Keller, 2003); (b) providing value-added product and service features to enhance brand-augmentation (Magrath, 1997); and (c) offering strong and effective design capacity for brand tiering (Magrath, 1997). Implications Based on the findings, implications for Chinese apparel manufacturers who strive to upgrade with design innovation will be discussed.
