Introduction In 2011, consumers spent $ 6.6 billion on certified fair-trade products, for a 12% increase worldwide (Thompson, 2012). Fair-trade is a social movement aiming to set fair prices for products, alleviate poverty, and assist producers and workers marginalized by the traditional economic model. Online stores have emerged as an effective marketing channel for fair trade products due to their ability to inform and reach a broad range of customers for very low cost. And this trend piques our interest in examining fair trade online stores. How do online fair trade retail stores rate in terms of usability? This is important because usability constitutes a key factor of online store quality. Usability refers to the perceived ease of navigating and/or making purchases through the retail website (Flavian et al., 2006). Previous studies find evidence that the richness of information related to products, culture, and artisans are criteria for success in fair-trade business (Lee & Littrell, 2005). Incorrect and/or low quality information undermine consumer interest in ethical products and subsequently, reduce credibility of fair trade retailers and their products (Carrigan & Attalla, 2001; Maignan & Ferrell, 2004). Usability is a way to ensure information is presented in a manner that will engender the trust of consumers. Trust is defined as the willingness of a consumer to be vulnerable to the actions of a retailer based on the expectation that the retailer will perform a particular action (cf. Mayer et al., 1995). Trust is known to be an antecedent in building relationships (Rotter, 1971). Fair trade retailers operating online stores must consider two types of trust. One type is customers’ trust toward fair trade retailers. To create such trust, fair trade retailers must convey that the marginal price differences between fair trade products and commercial products will be used to help producers (Castaldo et al, 2009), and must be transparent in communicating the operational processes underlying fair trade retailing. The other type of trust is related to the website and reflects skepticism about completing transactions online (Gefen & Straub, 2003). Compared to a brick-and-mortar store, online customer’s trust is critical since a customer’s perceived risk in purchasing goods online can be reduced by trust (Ha & Stoel, 2008; Pavlou, 2003). Lack of social presence for an online store impedes development of a customer’s trust toward the retailer (Gefen & Straub, 2003). Building upon the existing literature, we posit that a low level of usability, due to its role in developing online interactivity and engagement, will lead to lack of trust building, which is critical in promoting the sale of fair trade products. The purposes of this study are (1) to propose how usability, interactivity, and engagement can improve trust building, and (2) to provide empirical evidence of the lack of usability, interactivity, and engagement in current fair trade online stores. Website usability allowing consumer interactivity and engagement is an essential website attribute for formulating trust. Thus, the goal of this study is to provide suggestions for competitive e-retailing strategies for fair trade retailers based on results of a benchmarking study comparing websites of commercial and fair trade retailers. Literature Review Website Usability. Usability is created through the use of advanced website attributes that allow greater involvement of customers. Website usability not only influences consumer attitudes but also trust toward the website or company (Childers et al, 2001; Roy et al., 2001). Recently, scholars have suggested usability is related to engagement (Quesenbery, 2003). For instance, insufficient usability may be a factor in failing to engage consumers with the website; conversely, engagement can be sustained when attributes of usability meet user needs (O’Brien & Toms, 2008). Website usability may have a direct impact on enhancing interactivity. Interactivity. Interactivity refers to the extent to which users can participate in communication, user control, and entertainment (cf. McMillan & Hwang, 2002). Based on this notion, two types of interactivity within the e-commerce context are examined: (1) website interactivity concerns the website design and attributes enabling consumer interaction with the site to make decisions and personalize content (Merrilees & Fry, 2003), and (2) social interactivity promotes ‘consumer-to-consumer’ and ‘consumer-to-company’ communicative interactions within virtual social space provided by the retailer (Chan & Li, 2010; Nambisan & Watt, 2011). The outcomes of interactivity are two-fold. First, interactivity promotes customer engagement with brands (Ha & James, 1998). Consumers’ interaction with other consumers and the company (via social interactivity) and navigating and personalizing the website (via website-interactivity) create psychological engagement with the company. Second, interactivity entices consumers to acquire greater amounts of information from the website, which subsequently has a positive impact on trust towards the online retailer (Ballantine, 2005; Chen et al, 2005). Consistent with this view, Merrillees and Fry (2003) claim that the level of perceived interactivity is a predominant determinant in constructing trust in the online domain. Engagement. Consumer engagement behavior refers to the creation of an enduring and meaningful relationship between the company and the consumer (Doorn et al. 2010). Consumer engagement involves a highly interactive and experiential process. Highly engaged consumers integrate product knowledge and exchange information with other consumers (Borle et al. 2007). Engagement behaviors facilitate consumer trust towards products and the company (e.g. Pigg & Crank, 2004). Social engagement, the spontaneous information exchange among users, can justify one’s purchase decision. The consumer-generated content becomes a more trustworthy source of knowledge than the information promoted by the retailer (Chan et al., 2010). The relationship between interactivity and engagement is reciprocal. Consumers highly involved in engaging with others are likely to utilize more website attributes promoting interactivity. Method The data for this study were collected from 28 commercial apparel retailers and 22 fair trade apparel retailers based in the US. The 22 fair trade retailers consisted of 13 for-profits and 9 non-profits. The sample was selected based on previous studies (i.e., Lee, Geistfeld, & Stoel 2007; Halepete & Park, 2006; Park & Stoel, 2002), trade publications, and a Google search. A binary measurement instrument was employed to categorize website content as either ‘available’ or ‘not available’ on both the commercial and fair trade store websites. In order to minimize any bias occurring from subjective evaluation of website content, two graduate students separately coded the data, and compared coding sheets. Differences were discussed until agreement was reached. Frequency counts were used to describe the availability of website and social interactivity related content. Chi-square analysis was used to identify statistically significant differences between commercial and fair trade online retailers. Results To assess website interactivity, we examined six attributes that facilitated convenience for consumers in locating information or customizing website content. They included (1) search engine navigation, (2) picture enlargement, (3) matching item suggestion, (4) log-in to own personal account, (5) styling suggestions by other consumers, and (6) picture rotation function. Analysis (chi-square) confirmed significant differences in availabilities of search engine navigation, picture enlargement, matching item suggestion, and log-in to own personal account. Interestingly, only two commercial retailers and one fair trade company were equipped with a product or styling suggestion technology. The use of 360-degree view of products was not used by any of the sample companies [commercial retailers (n=0); fair trade retailers (n= 0)]. To assess social interactivity, we analyzed attributes that facilitate relationships. The attributes are categorized into the following dimensions: 1) social media utilization, 2) social commerce, and 3) customer engagement. We examined the following five attributes constituting social interactivity: 1) existence of social media sites including Facebook, Twitter, and YouTube, 2) consumer Facebook sharing, 3) link to other retailers’ websites, 4) online chatting, and 5) consumer review section. Analysis showed the differences between commercial and fair trade retailers were all statistically significant. Conclusion & Implications This study examined the differences between commercial and fair trade retailers to evaluate the current status of fair trade retailers in terms of interactivity and engagement in managing their websites. We identified attributes where fair trade retailers lagged and these could hinder trust development with consumers. We address three implications applicable to fair trade retailers, and more broadly, retailers selling ethical products. First, website interactivity attributes that provide effective ways to communicate product, store and fair trade information are critical when the concept of fair trade is still unknown to a large segment of consumers. The focus of fair trade retailers should remain not only in delivering creative and high quality products, but also well-managed websites that can attract, educate, and engage consumers via interesting cultural products (Lee & Littrell, 2006). In doing so, advanced website interactivity attributes that enhance the convenience of online shopping, increase ease of navigation, and ensure competent delivery of information should be incorporated in fair trade company websites. Second, the lack of use of social media by fair trade retailers is concerning. Word-of-mouth (WOM) communication is innate to social media, and encourages spontaneous communications among consumers. Utilizing various social media platforms is an efficient way to generate consumers’ voluntary exposure to fair trade products at a minimal cost. Encouraging customers to share WOM would be a natural path to increase engagement, and spread the concept of fair trade. Moreover, when a consumer spreads fair trade product information on his or her social media networks, the people who will be viewing the information have already established a relationship with him or her, and such messages are perceived to be more credible than information shared by the company or unknown strangers (Chu & Kim, 2011). In addition, virtual space inviting consumer feedback on the company website or social media sites can stimulate interactions with unknown consumers. The third person point of view by unknown consumers compared to fair trade retailers may be perceived to be unbiased, and consequently accepted as more trustworthy. Third, the concept of social commerce, referring to the practice of featuring links of other company websites on one’s own website, is critical to enhance the overall visibility and traffic to fair trade e-commerce sites. The unique feature distinct to fair trade retailers is their shared use of ‘certified fair trade’ labeling. While commercial apparel retailers promote their brand to generate corporate profits, the vision of fair trade retailers is to promote their products to bring social welfare. Thus, the union of fair trade retailers and collective initiatives can create synergy. Integrating the concept of social commerce with collective initiatives is one practical way to achieve this objective. Considering this common denominator across fair trade retailers, the use of fair trade labeling and links to other fair trade retailers on the website will support greater exposure to potential consumers and engagement with diverse fair trade retailers. Two major challenges fair trade retailers face are that: (1) their small size fails to generate economies of scale, and (2) due to the absence of national chains or organizations managing fair trade stores, brick-and-mortar fair trade stores are not evenly distributed geographically. Therefore, an interactive and engaging online presence for fair trade retailers is critical in resolving these limitations. It is a way to reach a large segment of consumers who do not reside around brick-and-mortar fair trade stores. We hope that interactivity and engagement will increase consumer exposure to fair trade retailers and ultimately increase fair trade sales.

This study proposes the use of fashion as a tool of psychotherapy for individuals feeling social and psychological pressure due to society’s emphasis on appearances. The concept of fashion therapy was re-established, and theories (cognitive behavioral therapy, person-centered therapy, solution-focused brief therapy) founded on art therapy were introduced. Based on past research, this study developed a process for fashion therapy.

Network analysis of keywords relevant to three fashion trading areas, Garosu-gil, Dongdaemun, and Itaewon in Seoul, Korea, revealed that ‘associated industry’ is an important factor along with ‘design’ and ‘brand’. Additionally, distinct attributes of each commercial district can serve as differentials to attract consumers; thus, they are necessary factors in order to develop as fashion trading areas.

The efficacy of chemical disinfectants is reduced owing to the inactivation of active ingredients after dilution. This study investigated the effect of time on the efficacy of six different disinfectants, after dilution, against avian influenza virus. When used at the recommended concentration, most disinfectants showed efficacy at a high concentrations in the presence of organic materials immediately after dilution, while sodium dichloroisocyanurate-based products, after dilution, showed reduced efficacy over time at low concentrations in the absence of organic materials. Most disinfectants were neutralized by organic materials; however, this could be compensated for by increasing the product dosage. For successful decontamination in farms, disinfectants should be used at high concentrations in accordance with the manufacturers’ recommendations. Furthermore, the presence of organic materials must be taken into consideration, and diluted disinfectant solution should be prepared no more than a day before use.

This study explains an agricultural mobile commerce case using Oauth Based Real-Time Information Sharing Technique according to the growth of the agricultural e-commerce market. Considering the characteristics of the agricultural market, it can confirm differential values with the existing agricultural mobile commerce market according to the functions and characteristics of its technique. We compare variables for introducing agricultural mobile commerce with the existing mobile commerce. Trust through information sharing with real-timefarming diaries, suitability and perceived ease of use variables are positively influenced, but influence on completeness and authority of information variables are relatively insufficient. Through this, we explained differential values of agricultural mobile commerce and suggested an applicable business model.

The rice green caterpillar Naranga aenescens Moore (Lepidoptera: Noctuidae) is one of important destructive insect pests to Poaceae including rice and corn. We investigated the development periods of N. aenescens egg, larva, pupa and total immature at eight constant temperatures of 15.0, 17.5, 20.0, 22.5, 25.0, 27.5, 30.0, and 32.5°C, respectively. N. aenescens developed successfully from egg to the adult stage at all temperatures tested except 15.0°C. Developmental rate of N. aenescens increased as temperature increased from 15.0 to 30.0°C but declined at 32.5°C except pupa stage. The lower developmental threshold (LDT) and thermal constant (K) was estimated by linear regression. Higher temperature threshold (TH) and lower temperature threshold (TL) were calculated by two nonlinear functions. LDT and K from egg to adult emergence were 12.01°C and 330.84DD. The temperature range of N. aenescens from TL to TH using performance model (24.03) was wider than that from SSI model (19.77). Developmental completion of N. aenescens was described using a two-parameter Weibull distribution model. The adult emergence frequency of N. aenescens over full range of constant temperatures was simulated using developmental rate functions and Weibull function.

Species diversity of ant fauna inhabiting the university campus in the Seoul Metropolitan city, Hanyang University is documented in this investigation. Totally, 14 species of 8 genera belong to 3 subfamilies discovered in study area. Our results are compared with the previous works on ant fauna in the forest and urban habitats based on species number difference. In study area, site 12 and 13 contain wide forest area and diverse environmental elements such as rotten wood, leaf mold and group of living tree. Site 7 has small forest area, but show wide variety of environments like site 12 and 13. Urbanized region like site 8, 10 or area in construction like site 1 show the most lowest diversity. Aside from diversity, Four ant species, Paratrechina flavipes, Lasius spp., Camponotus japonicas, Tetramorium caespitum, appear at almost all habitat, seems to have strong tolerance to environmental change.

Vollenhovia emeryi (Hymenoptera: Myrmicinae) is dimorphic in its wing morphology of alate females: the long-winged and the short-winged. In our previous study, we found that the long-winged is ancestral and the short-winged is derived. Intriguingly, the former is infected with the intracellular symbiotic Wolbachia bacterium and the derived is void of the bacterium indicating that the latter somehow evolved resistance to the bacterium. This may be one of few cases in which transition from susceptibility to the bacterium can be traceable via the divergence estimation. As a consequence, we inferred that the two morphs diverged approximately quarter million years ago; a remarkably recent event in evolutionary perspective. In this presentation, we will further discuss genetic orchestration in the host insect and future research directions.

Osteocalcin (OC) is the most abundant noncollagenous protein of extracellular matrix in the bone. In an OC deficient mouse, bone formation rates are increased in cancellous and cortical bones. OC is known as a negative regulator of mineral apposition. OC is also expressed in the tooth of the rat, bovine, and human. However, little is known about OC during tooth development in Xenopus. The purpose of this study is to compare the expression of OC with mineralization in the developing tooth of Xenopus, by using von Kossa staining and in situ hybridization. At stage 56, the developmental stage of tooth germ corresponds to the cap stage, and an acellular zone was apparent between the dental papilla and the enamel organ. From stage 57, calcium deposition was revealed by von Kossa staining prior to OC expression, and the differentiated odontoblasts forming predentin were located at adjoining predentin. At stage 58, OC transcripts were detected in the differentiated odontoblasts. At stage 66, OC mRNA was expressed in the odontoblasts, which was aligned in a single layer at the periphery of the pulp. These findings suggest that OC may play a role in mineralization and odontogenesis of tooth development in Xenopus.

We created species richness maps of mammals, birds and plants using "Nnational Ecosystem Survey" data and identified correlations between species richness maps of each taxa. We examine the distribution of species richness of each taxa and calculated conservation priority rank through plotting species-area curves using an additive benefit function in Zonation. The conclusions of this study are as follows. First, plant showed high species richness in Gangwon province and Baekdudaegan, and mammals showed high species richness at eastern slope of Baekdudaegan in Gangwon province unusually and the species richness of mammals distributed equally except Gyeonggi and Chungnam province. However, birds showed high species richness in the west costal because the area is the major route of winter migratory birds. Second, correlation of each taxa’s distribution is not significant. Correlation between mammals and birds is positive but correlations between birds and others are negative. Because mammals inhabit in forest but birds mostly live in coastal wetlands and rivers. Therefore, bird’s habitats are not shared with other habitats. Third, the probability of mammals occurrence is very low under 25% in species-area curve, others increase proportionally to area. Birds increase dramatically richness at 10% because bird's habitat is concentrated in coastal wetlands and rivers. Plants increased gently species richness due to large forest in Gangwon province. We can calculate the predicted number of species in curves and plan various conservation strategies using the marginal number of species. Finally, high priority ranks for conservation distributed mainly in Gangwon province and Baekdudaegan. When we compared with priority map and terrestrial national parks, the parks were evaluated as high priority ranks. However, the rank of parks away from Baekdudaegan was low. This study has the meaning of selecting conservation priority area using National Ecosystem Survey. In spite of the omission of survey data in national parks and Baekdudaegan, the results were good. Therefore, the priority rank method using species distribution models is useful to selecting protected areas and improving conservation plans. However, it is needed to select protected areas considering various evaluation factors, such as rarity, connectivity, representativeness, focal species and so on because there is a limit to select protected area only using species richness.

Despite the general understanding of the prominent role of basic reading sub-skills, such as decoding abilities and reading fluency, in the reading comprehension of younger and proficient first and second language readers, little is known about the role of these skills in older and less skilled readers in foreign language contexts. The present study was designed to investigate how decoding skills and reading fluency relate to the reading comprehension of such readers, and to identify the relative strengths between the two. Two hundred twenty two Korean high school students participated, and their performance on decoding, reading fluency, and reading comprehension tasks was analyzed. The results showed that both decoding skills and reading fluency were strongly correlated to reading comprehension. Moreover, between the two fundamental reading sub-skills, decoding skills outperformed reading fluency in explaining reading comprehension, making a unique contribution beyond the effects of reading fluency. These findings suggest that a basic skill like word decoding still deserves instructional attention even at the secondary schools in EFL contexts.

Salmonellosis is a significant public health concern and a major cause of bacterial foodborne poisoning in Korea. Approximately 95% of salmonellosis cases in humans are related to the intake of contaminated food products, which mostly originate from livestock such as poultry, pigs, and cattle. To successfully develop strategies to reduce the spread of Salmonella, it is important to investigate the prevalence of Salmonella spp. isolated from food animals and meat. In Korea, the prevalence of Salmonella spp. in cattle was 1.2 2.0%, whereas in pigs it was 1.5 21%. Of all livestock and meat products analyzed, the Salmonella isolation rate was the highest in chickens (18.8 30.3%) and their meat. Antibiotic resistance is an important social issue. The frequent use of antibiotics in the livestock industry has led to increased antibiotic resistance in Salmonella isolates that are extracted from livestock, which raises serious public health concerns. To prevent the spread of antibiotic resistance, it is essential to collect data related to antibiotic-resistant Salmonella strains isolated from food animals and meat. Antibiotic resistance tests revealed that Salmonella isolated from cattle, pigs, and poultry were highly resistant to tetracycline and streptomycin. Recent studies show that the overuse of antibiotics in food animals can also affect antibiotic resistance in humans. Therefore, it is important to establish an appropriate management strategy to successfully prevent misuse of antibiotics within the Korean livestock industry.
