  • 컨텐츠 중심 네트워크(CCN)는 데이터 송수신을 위해 IP 주소로 종단 간 1:1 연결을 맺어야 하는 기존 인터넷의 비효율성을 해결하고자 등장한 미래 인터넷 기술 중 하나이다. CCN은 IP 주소 대신 컨텐츠의 이름을 사용하여 라우팅을 수행하며 네트워크상의 노드들이 컨텐츠를 저장하고 컨텐츠를 요청하는 인근의 소비자들에게 배포하는 방식을 사용한다. 하지만 기존의 CCN은 최초 데이터 패킷이 도착한 하나의 경로로만 컨텐츠를 수신하고 이후에 도착한 데이터 패킷은 폐기하기 때문에 전송률과 대역폭 측면에서 비효율적이다. 따라서 본 논문에서는 다수의 노드에 서로 다른 데이터 청크를 요청하여 다중경로를 통해 컨텐츠를 효율적으로 수신하는 기법을 제안한다.

  • 환경에 대한 관심이 증가하면서 소비자에게 판매한 제품이 사용 후 생산자에게 되돌아오는 과정에서 발생하는 waste를 줄이기 위한 역공급사슬(Reverse Supply Chain)의 개념이 발생하게 되었다. 특히 폐자동차의 경우는 다른 제품에 비하여 중량이 상대적으로 커서 폐기되는 양이 많고 환경에 유해한 재질이 많이 포함된 대형 내구성 폐기물이다. 그런데 이러한 폐자동차는 폐차장이라는 한정된 곳에서 발생하는 것이 특징이므로, 수거 및 회수 체계가 잘 관리된다면 보다 큰 재활용 효과를 얻을 수 있다. 이 논문에서는 현재의 수거 시스템 상에서 폐자동차 부품의 재활용이 가지는 경제성을 살펴보고, 자동차 부품의 재활용 또는 재 이용률을 높이기 위한 폐자동차의 역공급사슬을 새로이 제안하였다. 개선된 역 공급사슬에서는, 자동차 판매업체(제조업체)가 주도적으로 부품 재활용에 참여하게 된다.

  • NFC(Near Field Communication)는 10cm 이내의 거리에서 무선기기 간의 통신을 가능케 해주는 기술로 13.56 Mhz RF(Radio Frequency) 주파수 대역을 이용한 비접촉식 근거리 무선통신의 한 종류이다. 올해 출시되는 대부분의 스마트 폰에서 NFC 기능을 탑재하며, NFC기반의 모바일 결제 서비스가 가장 유망한 결제 방식으로 주목 받고 있다. 소비자는 NFC 모바일 단말기를 가지고 판매자의 POS(Point of Sale) 단말기와 근접 통신을 통해 결제를 진행하는 방식으로 다른 무선 통신 방식 (RFID, Bluetooth 등)보다 보안 취약성이 높지 않지만, 기존의 RFID 환경에서 일어날 수 있는 기술적 취약점과 비슷한 유형의 위협이 충분히 발생할 수 있으므로 유효한 보안 기술이 필요하다. 본 논문은 안전한 NFC 모바일 결제 환경을 구축하기 위한 공개키 알고리즘인 타원곡선 암호ECC(Elliptic Curve Cryptosystem)를 적용한 Bilinear Pairing을 활용해서 효율적이고 보안성도 강력한 인증 메커니즘을 제안한다.

  • Rapid development of the information technology has influenced on the changes in every sector of human environments. One prominent change in retail market is an increase of electronic stores, which has prompted practical and research interest in the product and store attributes that include consumer to purchase products from the electronic shopping. Therefore many marketers are paying much attention to the criteria of evaluating clothing and web service on internet shopping malls. The purpose of this study is to examine differences of clothing and web service criteria of consumer groups (High-Involvement & High-Ability, Low-Involvement & High-Ability, High-Involvement & Low-Ability, and Low-Involvement & Low-Ability) who are classified into consumer involvement and internet use ability. The subjects of this study were 305 people aged between 19 and 39s, living in Seoul and Gyeonggi-do area, and having experiences in buying products on the internet shopping. Statistical analyses used for this study were the frequency, percentage, factor analysis, ANOVA and Duncan test. The results of this study were as follows: Regarded on the criteria of evaluating clothing, the low different groups had significant differences in the esthetic, the quality performance and the extrinsic criterion. Both HIHA group and HILA group showed the similar results. They considered every criterion of evaluating clothing more important, compared with other groups. Regarded on the criteria of evaluating web service related to the low different groups, there were significant differences in the factors related to the shopping mall reliance, the product, the satisfaction after purchase, and the promotion and policy criterion. Both HIHA group and HILA group showed the similar results as well. They considered every criterion of evaluating web service more important, compared with other groups. In conclusion, HI groups perceive relatively more dangerous factors which can be occurred during internet shopping. Therefore, internet shopping malls need to provide clothing that can satisfy the HI groups as well as make efforts to remove the dangerous factors on the internet.

  • This paper revisits two conventional beliefs of environmental nonmarket valuation and examines their weaknesses and a new opportunity. The two beliefs are that willingness to pay (WTP) is an appropriate measure of nonmarket behaviour and that exogenous variables are relevant predictors of WTP whilst endogenous variables are not. The contemporary literature in psychology and economics is reviewed to demonstrate departures from these two beliefs. Tackling heterogeneity in stated preferences, both socio-demographic and psychological variables should be measured simultaneously to explain and predict choice behaviours more accurately.

  • Recently, the high growth rate and advantages of the crowdfunding market have also led to increased participation of brands and companies, and this also applies to fashion business. Risk has been noted to be a key factor in consumer behavior in crowdfunding. With the high-risk context of crowdfunding where supporters inevitably bear to pay full amount of price before receiving the actual products. Factors enhancing or inhibiting perceived risk of crowdfunding need to be explored. The past literature on perceived risk and consumer attitudes in crowdfunding has expanded, but it has rarely covered the context of experience goods such as fashion products. In addition, the platform characteristics in relation to perceived risk should be addressed. The current study attempts to address the effect of the perceived amount of information offered in a fashion crowdfunding project on perceived risk and the intention to participate in the project. For the experiment of this study, a fictitious crowdfunding page for fashion products was set as the stimuli. A total of 240 Korean participants were recruited and their responses were statistically analyzed using SPSS 24.0 software. In the results, the greater the amount of detailed information about the fashion crowdfunding project, the higher the intention to participate the project. The greater the amount of information provided, the lower the perceived risk of consumers. Moreover, the lowered perceived risk affected the intention of participate. Perceived risk has a partial mediation in the relationship between the amount of information and intention to participate. Theoretical and managerial implications are discussed.

  • 우리나라는 "제 3차 신재생에너지 기술개발 및 이용 보급 기본계획"을 통해 2030년까지 111.5조 원을 투자하여 전체 에너지의 11%를 신재생에너지로 공급한다는 목표를 설정하였다. 그러나 신재생에너지는 기존의 원자력이나 화석에너지에 비하여 생산비용이 높아 보조나 융자 등의 정부지원에 의존하여 보급이 이루어져왔다. 신재생에너지 보급확대 및 산업발전을 위한 보급정책의 일환으로 정부는 2012년부터 RPS(Renewable Portfolio Standard, 신재생에너지 공급의 무화제도)를 도입키로 확정하였다. RPS의 도입은 일정규모 신재생에너지 시장수요를 창출함과 동시에 신재생에너지원간 가격경쟁 구도 형성의 유인이 될 수 있다. 이는 전력가격 일괄상승 및 녹색가격제도(Green Pricing) 등의 정책적 논의로 이어질 수 있다. 따라서 소비자 측면에서 신재생에너지 전력의 가치를 어떻게 평가하는지를 분석하여 RPS 시행제반의 정책적 논의의 기초자료를 마련할 필요가 있다. 특히 RPS는 신재생에너지원 간의 경쟁을 가능하게 하므로 개별 신재생에너지원에 따라 소비자 선호의 차이가 어떻게 나타나는지 연구되어야 한다. 이에 본 연구는 환경재 혹은 비시장재화의 가치추정에 가장 널리 활용되고 있는 조건부가치평가법(Contingent Valuation Method; CVM)을 적용하여 풍력, 태양광, 수력으로 생산한 전력에 대한 소비자의 지불의사액(Willingness to Pay; WTP)을 분석하는 모형을 수립하였다. 이를 위해 Zografakis et al.(2010), Yoo and Kwak(2009), 이창훈 황석준(2009), Nomura and Akai(2004), Bately et al.(2001) 등의 선행연구를 참조하여 신재생에너지 전력 가치의 설문에서 고려되어야 하는 요인들을 선정하였다. 이를 토대로 설문 시나리오를 작성하여 각 요인들이 신재생에너지 전력에 대한 지불의사액 결정에 어떠한 영향을 미치는지 분석가능한 모형을 설정하였다. 뿐만 아니라 기존 연구들이 신재생에너지로 생산된 일반적인 전력에 대한 지불의사액을 질문하는데 그쳤다면, 본 연구에서는 각 원별로 지불의사액의 차이를 도출할 수 있는 설문모형을 구축하는데 중점을 두었다. 본 연구결과는 향후 설문수행을 통하여 신재생에너지원별로 소비자의 선호를 분석할 수 있는 연구로 발전될 수 있으며, 이는 RPS 도입으로 인한 전력가격 정책 수립의 기초 연구자료로 활용될 수 있다 하겠다.

  • 1. Research Purpose Consumers rely on various clues to evaluate their decision to patronize a retail store, and store brand is one of them (Dodds 1991; Grewal et al. 1998). As consumers find ever increasing variety of contact points connecting them to specific store, the value of experiential shopping as a means of increasing store's brand equity warrants greater attention from scholars of retail management. Retail shopping values are credited for creating not only cognitive experiences like brand knowledge but also emotional experiences such as shopping pleasure and pride (Schmitt 1999). This may be because today's consumers place emphasis on emotional values associated with shopping pleasure, lifestyle brought to life, brand relationship, and store atmosphere more than utilitarian values such as product quality and price. Many previous literature found this to be true (Ahn and Lee 2011; Mathwick et al. 2001). This brings forth important research issues and questions regarding the roles of shopping experiential values and brand equity with regard to consumer's retail patronage choice. However, despite this importance, research on this area remains quite inadequate (Hwang 2010). For this reason, this study aims to verify the relationships among experiential shopping values, retail store brand equity and tries to link that with customer loyalty by surveying large-scale discount store shoppers in Korea and China. 2. Research Contents In order to carry out the research objective, this study conducted comprehensive literature survey on previous literature by discussing major findings and implications with regard to shopping values and retail brand equity and store loyalty. For data collection, researcher employed survey-based research method where data were collected in two major cities of Korea (Seoul) and China (Bejing) and sampling frame was based on patrons of large discount stores in both countries. Specific research questions raised in this study are as follows; RQ1: How do Korean and Chinese consumers differently perceive of shopping values regarding shopping at large-sclae discount stores? RQ2: Are there differences in consumers' emotional consumption propensities? RQ3: Do Korean and Chinese consumers display different perceptions of brand equity towards large-scale discount stores? RQ4: Are there differences in relationships between shopping values and brand equity for Korean and Chinese consumers? For statistical analysis, SPSS17.0, AMOS17.0 and SmartPLS were employed. 3. Research Results The data collected through face-to-face survey conducted in Seoul and Bejing revealed appropriate data validity and reliability as a result of exploratory/confirmatory factor analysis and reliability tests, andh SEM model yielding satisfactory model fitness. The result of the study may be summarized by three main points. First, as a result of testing differences in consumption dispositions, Chinese consumers showed higher scores in aesthetic and symbolic dispositions, whereas Korean consumers scored higher in hedonic disposition. Second, testing on perceptions toward brand equity of large discount stores showed that Korean consumers exhibited more positive perceptions of brand awareness and brand image than Chinese counterparts. Third, the result of exploratory factor analysis on the experiential shopping values revealed different factors for each country. On Korean side, consumer interest value, aesthetic value, and hedonic value were prominent, whereas on Chinese side, hedonic value, aesthetic value, consumer interest value, and service excellence value were found salient. 4. Research Implications While many previous studies on inter-country differences in retailing area mainly focused on cultural dispositions or orientations to explain the differences, this study sets itself apart by specifically targeting individual consumer's shopping values from an experiential viewpoint. The study result provides important theoretical as well as practical implications for large-scale discount store, especially the impotance of fully exploring the linkage between shopping values and brand equity, which has significant influence on loyalty. Therefore, the specific implications deriving from the result shed some important insights upon the consumption values based on shopping experiences and brand equity. The differences found in store shoppers between the two countries may also provide useful insights for Korean and Chinese retailers who plan to expand their operations globally. Related strategic implications derived from this study is the importance of localizing retail strategy which is based on the differences found in experiential shopping values between the two country groups. Especially the finding that Chinese consumers value consumer interest and service excellence, whereas Koreans place importance on hedonic or aesthetic values indicates the need to differentiate the consumer's psychographical profiles when it comes to expanding retail operations globally. Particularly important will be to pursue price-orienated strategy in China in consideration of the high emphasis on consumer interests and service excellence, but to emphasize the symbolic aspects of brand equity in Korea by maximizing the brand equity associated with aesthetic values and hedonic orientations. 5. Recommendations This study focused on generic retail branded discount stores in both countries, thus making it difficult to tease out store-specific strategies based on specific retail brands. Future studies may benefit fro employing actual brand names in survey questionnaire to verify relationship between shopping values and brand-based store strategy. As with other studies of this nature, this study needs to strengthen the result's generalizability by selecting respondents from a wider spectrum of respondents.

  • The purposes of this study were (1) to analyze price sensitivity, (2) to define the range of acceptable prices for each foreign segment, and (3) to provide a price model for Korean traditional restaurants. From October to November, 2006, a total of 781 foreigners responded to individual surveys. Statistical analyses on the survey data were performed using descriptive statistics and Price Sensitivity Measurement (PSM). Major findings from the study are as follows: First, the ranges of the acceptable prices were $98$\sim$$130 for fine dining/gourmet restaurants, $70$\sim$$90 for theme/ambience restaurants, $40$\sim$$60 for popular/family restaurants, and $18$\sim$$30 for convenience/fast food restaurants. Second, the convenience/fast food restaurants showed the highest price sensitivity. Third, a low stress level and wide range of the acceptable price were observed for the fine dining/gourmet restaurants, suggesting that the price sensitivity of the fine dining/gourmet restaurants was quite low. Finally, the price sensitivity indicated by the Japanese was higher than by the other groups. In consequence, the research findings suggest that the managers of the Korean traditional restaurants should strategically plan prices by understanding different customers' price sensitivity within and between customer segments. Through additional research, marketers can compare perceptions of specific brands, the competition, and variations within a product line.
