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 aimed to evaluate the TAC policy and to examine the effective annual TAC quota in the sandfish stock rebuilding plan using a bioeconomic modelling method. In the analysis, first, a sandfish bioeconomic model was developed by combining a sandfish stock population model and economic models by fishery and second, achieving stock rebuilding targets and changes of fishing revenues by the level of annual TAC quota were examined. Model results indicated that the TAC 1,500ton policy would have the greatest impact on the increase of sandfish stock biomass comparing to the status quo and other TAC policies. In addition, it was evaluated that the total fishing revenues of coastal gillnet and danish seine fisheries could be increased the most in the TAC 2,500ton policy. In both cases of TAC 3,500ton and 4,000ton, the fishing revenues of both fisheries were inversely reduced due to the decrease of catch by coastal gillnet and the decline of market prices by danish seine’s excessive catch. Furthermore, they would have a negative impact on sandfish stock biomass.

유도용액으로 비료를 사용하는 정삼투식 해수담수화에서 유도용액의 성능을 평가하였다. 일반적으로 많이 사용되는 비료 중에서 삼투압, 용해도 및 pH 등을 고려하여 NH4NO3, NH4H2PO4, (NH4)2HPO4, KCl, KNO3 및 KHCO3를 유도용액 후보군으로 선정하였다. 수투과선속, 질소와 인의 역용질선속 및 비역용질선속을 측정하여 유도용액의 성능을 평가하였다. KCl은 본 연구에서 선정된 유도용액 중에서 가장 높은 수투과선속을 나타낸 반면에 (NH4)2HPO4는 가장 낮은 수투과선속을 나타내었다. NH4H2PO4가 가장 낮은 역용질선속 및 비역용질선속을 보였으며, (NH4)2HPO4 ＜ KNO3 ＜ NH4NO3의 순서로 역용질선속 및 비역용질선속이 증가하였다. NH4H2PO4는 비록 다른 유도물질에 비해 수투과선속이 낮으나 비료의 주요 성분인 질소와 인을 모두 포함하고 있을 뿐만 아니라 질소와 인의 역용질선속 및 비역용질선속이 다른 유도물질에 비해 매우 낮으므로 FDFO (fertilizer drawn forward osmosis)에서 효과적으로 사용될 수 있을 것으로 판단된다.

Hazardous air pollutants such as NO2, VOCs and PM10 were measured Daegu, Korea in major micro-environments,where housewives spend the most of their time, and personal exposure times were estimated by using time activitypatterns and exposure scenarios. The major microenvironments of housewives were selected using the ‘Time-UseSurvey’ conducted by the National Statistical Office in Korea in 2009. A total of 4,514 (weekdays) and 3,063(weekends) housewives were recruited for the ‘Time-Use Survey.’ It seems that housewives are spending about80% of their time in the house, and about 5% of their time outdoors during weekdays and weekends. The indoor/outdoor ratio of the average concentration of NO2 was more than 1, which indicated that the source was indoors.Toluene was shown to have higher concentrations indoors than outdoors. Ethylbenzene and xylene displayedsimilar characteristics to toluene, and the concentration ratio for indoor/outdoor was shown to be 1.29 ± 0.76 and1.04 ± 0.45, respectively, higher concentrations indoors. Based on the results of the time activity patterns ofparticipants, 3 kinds of exposure scenarios were formulated. The spent time and air concentration in eachenvironment were assumed as normal and lognormal distribution, respectively. And then the Monte-Carlosimulation was conducted. According to the result of the simulation, the exposures to hazardous air pollutantsrevealed an increasing pattern as housewives visits other indoor environments such as supermarkets.

This study aims to investigate the antecedents to customer retention and brand loyalty of Internet Service Providers in Thailand. The findings reveal that customers’ commitment and value are influenced by information support, privacy and security. Additionally, the positive relationships between information quality and privacy and behavioural loyalty were revealed. Customers’ commitment and value were positively associated with behavioural loyalty. However, surprisingly, there was no support for the hypothesised positive association between customers’ value with behavioural loyalty. Practical implications that can be drawn from this research will form a foundation for service providers in the residential internet market to develop new retention strategies. These providers would l be able to reduce the current issues relating to the high customer churn rate. By making customers more central in company operations, these strategies can potentially reduce the expenses associated with acquiring new customers.

Today's dynamic market necessitates the need for the marketing communication stimuli, which engages with the audience as consumers have become less attentive to traditional advertising. It is imperative to gain deeper understanding of how brand evaluations and subsequently brand relationships are created to allow for a successful marketing strategy. Within that context, the role of characters becomes important in placing brands in TV programmes as results of this study indicate that only character interacting with the placed brands were significant for the audience's likelihood to talk about the brands shown in a given placement sequence. Thus, industry practitioners may need to identify clear outcomes for the placed brand (generate awareness, enduring attitude/likability) before adopting the placement modality and media vehicle for its execution. The findings from this study provide promising results to strengthen the growing evidence of the importance engaging consumer experiences for effective buzz-marketing.

The aim of the present study was to evaluate the use of an immunochromatographic test (ICT) strip using recombinant MPB70 (rMPB70) protein as a complementary tool for the diagnosis of naturally occurring tuberculosis in cattle. The study was performed on 249 cattle from populations known to be free from Mycobacterium bovis (M. bovis) and 119 cattle with M. bovis infection, confirmed postmortem. Compared to reference standards (culture isolation and/or visible lesion), the sensitivity of ICT was 94.12% (95% CI: 89.89∼98.35%) while the specificity was 96.80% (95% CI; 94.62∼96.82%). The findings indicate that the ICT strip is efficient for diagnosing bovine tuberculosis in cattle from Korea.

PURPOSES : Traffic congestions which occur in the intersections of arterials lead to mobility and environment problem, and then traffic agencies and engineers have been struggling for mitigating congestions with greenhouse gas emissions. As an alternative of solving theses problems, this study is to introduce a low-cost and high-effectiveness countermeasure as unconventional intersections which are successfully in operation in U.S.. The main feature of unconventional intersections is to reroute turning movement on an approach to other approach, which consequently more green time is available for the progression of through traffic. Due to improved progression, this unique geometric design contributes to reduce delays with greenhouse gas emission and provides a viable alternative to interchanges. This study is to evaluate the potential operation and environment benefits of unconventional intersections. METHODS: This study used the VISSIM model with Synchro and EnViVer. Synchro is to optimize signal phases and EnViVer model to estimate the amount of greenhouse gas emissions by each condition. RESULTS : The result shows that unconventional intersections lead to increase the capacity and to reduce greenhouse gas emissions, compared to existing intersections. CONCLUSIONS: Unconventional intersections have the ability to positively impact operations and environments as a low-cost and higheffectiveness countermeasure

PURPOSES : This study is to evaluate the feasibility of using the alkali activated cement concrete for application of partial-depth repair in pavement. METHODS : This study analyzes the compressive strength of alkali activated cement mortar based on the changes in the amount/type/composition of binder(portland cement, fly ash, slag) and activator(NaOH, Na2SiO3, Na2CO3, Na2SO4). The mixture design is divided in case I of adding one kind-activator and case II of adding two kind-activators. RESULTS : The results of case I show that Na2SO4 based mixture has superior the long-term strength when compared to other mixtures, and that Na2CO3 based mixture has superior the early strength when compared to other mixtures. But the mixtures of case I is difficult to apply in the material for early-opening-to-traffic, because the strength of all mixtures isn't meet the criterion of traffic-opening. The results of case II show that NaOH-Na2SiO3 based mixtures has superior the early/long-term strength when compared to NaOH-Na2SiO3 based mixtures. In particular, the NaOH-Na2SiO3 based some mixtures turned out to pass the reference strength(1-day) of 21MPa as required for traffic-opening. CONCLUSIONS : With these results, it could be concluded that NaOH-Na2SiO3 based mixtures can be used as the material of pavement repair.

목적 : 캐나다작업수행측정(Canadian Occupational Performance Measure; COPM)이 정신과 작업치료 프로그램의 성과를 측정할 수 있는 타당한 평가도구인지 그 유용성을 확인하고자 하였다. 연구방법 : 본 연구는 2010년 9월부터 2011년 10월까지 경상도, 전라도, 충청도 소재의 정신보건기관에서 재활프로그램에 참여하고 있는 정신장애인 49명을 대상으로 하였다.환자가 인식한 문제 활동은 COPM, 이에 대한 수용도는 COPM 유용성 설문지를 사용하였으며 COPM의 기준관련타당도를 조사하기 위해 정신사회적 기능-증상 평가척도(Behavior and Symptom Identification Scale; BASIS-32)와 단축형생활기술척도(Abbreviated Life Skills Profile-16; LSP-16)를 활용하였다. 결과 : COPM 평가 후 유용성에 대한 질문에 대해 49명 중 46명(94.0%)이 치료계획을 세우는데 본인이 참여하는것이 도움이 된다고 답하였고, 본인이 수행하는데 어려움이 있는 것으로 인식한 영역은 생산적 활동이 87개(38.5%)로 가장 많았고 여가(35.0%), 자기관리(26.5%) 순이었다. COPM과 LSP-16, BASIS-32의 연관성을 분석한 결과 일부 하부항목을 제외하고 통계적으로 유의한 상관관계가 나타나지 않았다. 결론 : 본 연구 결과를 토대로 COPM은 국내 정신과에서 널리 사용되고 있는 평가도구들이 제공하기 어려운 정보, 즉 환자들이 스스로 인식한 문제들을 밝히는데 유용한 도구임을 알 수 있다. 또한 국내 정신장애인은 국외 장애인과는 달리 치료 목표로 생산적인 활동에 초점을 둔다는 본 연구의 결과는 정신과 재활 서비스에서 작업치료사의역할과 직업재활 프로그램의 중요성에 대해 시사 하는바가 크다고 할 수 있다.

수요대응형 교통수단(Demand Responsive Transit)은 변화하는 이동수요에 대응하는 탄력적인 교통수단으로 단순히 노약자와 장애인을 위한 복지교통 서비스의 영역이 아니라, 무선통신과 위치정보서비스(Location Based Service: LBS)의 발달로 인하여 도심형 수단으로 보다 효율적인 교통수단으로 자리매김하고 있다. 그러나 문전서비스(Door-to-Door)를 제공하는 수요대응형 교통수단 시뮬레이션에 적합한 상용툴의 부재로 인하여 알고리즘이나 차량 운행 요소를 면밀하게 분석하기 힘든 어려움이 있었다. 본 연구는 수요대응형 교통수단에 연관된 다양한 차량 운영계획과 알고리즘을 구현, 평가할 수 있는 시뮬레이션 환경을 제안한다. 문전서비스(Door-to-Door) 기반의 차량 운행 모형을 적용하기 위하여 확보되어야 하는 시뮬레이션 입력 데이터를 정의하고 있으며, 수요대응형 교통수단의 대표적인 범주에 속하는 실시간 합승 택시(Shared-Taxi) 서비스를 서울시 교통망과 택시 수요를 이용하여 적용하였다. 합승 택시 운행 계획을 위하여 Nearest Vehicle Dispatch(NVD)와 Insertion Heuristic(IH), 두 종류의 알고리즘을 제안하였으며, 제안된 시뮬레이션을 통하여 성능을 비교하였다. 또한, 합승(Ride-sharing)을 허용하지 않는 일반적인 택시와의 비교를 통하여 시스템 효율 향상과 서비스 품질 변화를 분석하였다.

자전거는 에너지 소모나 오염을 발생시키지 않는 지속가능한 녹색교통수단으로 정부는 자전거이용 활성화를 적극 추진하고 있다. 그러나 자전거 시장규모 증가와 함께 자전거 사고 또한 지속적으로 증가하고 있다. 현재 KHCM에서 제시하고 있는 자전거도로 평가는 자전거도로를 유형별로 구분하여 각기 다른 효과척도를 적용하여 자전거의 이동성과 안전성을 평가하고 있으며, 현장조사를 통한 자료수집을 통해 도로를 평가하고 있다. 본 연구에서는 공공자전거에 장착된 GPS수신기를 활용한 자전거 주행환경 평가 방안으로 수집된 자전거 주행속도자료를 이용하여 모든 자전거도로에 적용 가능한 구간단위의 자전거 주행환경을 평가하는 방법론을 제시하였다. 주행쾌적성 평가지표 개발을 위해 자전거GPS속도계를 장착한 실험자전거를 이용하여 도로선형, 신호교차로 및 과속방지턱의 유무 등 주행환경이 다른 자전거도로의 속도자료를 수집하였다. 분석시간동안 자전거 주행환경평가를 위해 자전거 주행속도 감소량을 분석하여 주행쾌적성을 0~1 사이의 값으로 계량화한 CCI(Cycling Comfortability Index)를 개발하였다. 실험구간별로 산출된 CCI를 분석한 결과, 주행쾌적성은 신호교차로와 종단구배의 영향을 많이 받는 것으로 나타났으며, 이를 바탕으로 도로환경에 따른 LOCC(Level of Cycling Comfortability)를 도출하였다. 본 연구의 결과는 GPS수신기를 장착한 공공자전거에 적용하여 자전거 교통의 모니터링 시스템으로 발전시키는데 유용한 기초자료로 활용될 것으로 기대된다.

본 연구에서는 한국산업표준에서 제시하는 콘크리트 강도 시험용 공시체를 이용하여 콘크리트 보강용 FRP의 부착 성능을 평가하기 위한 실험방법을 제안하고 이에 따라 FRP의 부착성능을 평가해 보도록 한다. 따라서 탄소섬유와 유리섬유로 이루어진 FRP를 두 겹으로 보강하여 양생한 철근 콘크리트 보에서 보강재의 탈락이 유도될 수 있도록 실험체를 설계하고, 3점 재하 시 적절한 파괴형상 및 부착강도가 나타나는 지를 실험을 통해 관찰하였다. 실험결과, 보강재의 탈락으로 인한 파괴가 유도되었으므로, 본 연구에서 제안된 실험방법을 통하여 크기가 작은 일반강도 콘 크리트 실험체에서 FRP의 부착강도를 평가할 수 있는 것으로 사료된다.

고객의 요구에 대한 빠른 대응과 유연하고 효율적으로 새로운 제품을 적기에 개발하기 위해서는 제품 플랫폼에 기초한 대량 맞춤이 절실히 요구된다. 이러한 목적을 달성하기 위하여 기업들은 상대적으로 생산비용을 낮게 유지하면서 대량생산의 이점을 유지하고 동시에 고객의 요구사항을 만족시키기 위해, product family를 도입하고 가능하면 작은 변화를 통하여 제품의 다양성을 유지하고자 한다. Product family를 설계할 때 중요한 이슈는 제품의 공통성과 차별성간의 절충점을 어떻게 찾아낼 것인가인데, 이를 위하여 개발된 것이 product family내에서 부품의 공통성을 평가하는 방법이다. 본 연구에서는 product family의 공통성을 평가하기 위해 개발된 대표적인 7가지의 공통성 평가방법을 여러가지 측면에서 비교분석한다. 이를 위하여 두 개 회사의 컴퓨터 마우스 제품군을 대상으로 공통성 평가를 위한 비교연구를 수행하였다. 추가적으로 본 연구에서는 product family를 설계하거나 재설계할 때 공통성 평가지수의 효과적이고 효율적인 사용방안을 위한 전략도 제시하였다.
