비트코인(Bitcoin)은 P2P 네트워크상에 존재하는 실물 없는 화폐이다. 비트코인의 특징은 발행 기관의 통제가 없는 분산 구조를 형성하고 네트워크가 연결된 곳 어디에서나 거래가 이루어질 수 있도록 신뢰성을 부여하고 있다는 것이다. 이러한 특징의 비트코인은 최초 등장 이래 하루 평균 약 21만 건, 1억 7천만 달러가 거래되는 규모로 성장했다. 화폐로서의 가치가 증가함에 따라 부당 이득을 취하려는 위협 또한 증가하게 될 것이다. 대표적으로 비트코인을 위협하는 행위로는 이중 지불, 부정 인출 등을 그 사례로 볼 수 있다. 하지만 아직까지 성장 단계에 있는 비트코인을 대상으로 발생될 수 있는 위협에 대한 인지는 부족한 실정이다. 이에 본 논문에서는 비트코인 신뢰 구조를 살펴보고 이를 기반으로 발생할 수 있는 다양한 위협들을 분석하고 대응방향을 제시하고자 한다.

VaR에 의한 금융위험의 측정은 국제결제은행 바젤위원회의 내부모델 허용에 힘입어 금융산업에서 표준방식으로 확고한 입지를 차지하고 있다. 본 연구에서는 한국주식시장포트폴리오를 거래투자자산으로 보유한 경우의 VaR를 극단치이론에 입각하여 측정하고 이의 성과를 RiskMetrics의 성과와 비교하여 검토하였다. GPD의 모수적 추정에 의한 VaR의 사후검정결과는 표본내 사후검정이나 표본외 사후검정에서 어떤 신뢰수준에서도 기대되는 범위와 크게 벗어나지 않은 안정된 결과를 보였다. RiskMetrics의 EWMA방식도 역시 표본내와 표본외 사후검정 어느 경우에나 기대되는 범위에서 크게 벗어나지 않았지만 높은 신뢰수준에서는 그 성과가 GPD VaR에 비하여 상대적으로 불안정하였으며 위험의 과소평가 성향을 확인할 수 있었다. 비모수적 GEV추정에 입각한 VaR의 경우에는 위험을 과대평가하고 지나치게 보수적인 성향을 나타내었다. GPD의 모수적 접근에 의한 VaR 측정은 다양한 신뢰수준에서 정확한 검정결과를 보여주고 있으며, 시간적 흐름에 따르는 VaR의 행태도 지나친 변동성을 보이지 않아 외부규제 및 내부통제를 위한 금융위험의 측정지표로서 실용적인 가치가 있음을 확인할 수 있다.

The purposes of this study are following. First, we want to review the relationship between trust and precedent variables including shared value, communication and opportunistic behavior in the on-line and off-line channel. Second, building the relationship among variables from previous research, we develop the research model. Third, based on the empirical analysis, we want to build the relationship among variables. Fourth, based on results of analysis, we want to elicit implications for marketing management from the trust in on-line channel in order to enhance the relationship commitment and customer loyalty. Theoretical implications of this study are following. First, under the multiple channel retailing environment, trust in on-line channel is influenced by the trust in off-line channel that the company is operating. Previous researches couldn't found this result because these researches divided on-line and off-line channel separatedly, Second, under the multiple channel retailing environment, on-line or off-line relational attributes including shared value, opportunistic behavior and communication have a effect on trust or relationship commitment So, shared value, opportunistic behavior and communication are very important variables having a effect on trust and relationship commitment in not only off-line channel but also on-line channel. Third, trust and relationship commitment were important mediate variables in multiple channel environment. This result goes with previous researches in single channel.

This study conducted a comparative study using Korean and Chinese consumer data to confirm the impact of K-beauty brand's CSR motivation on CSR authenticity and brand trust, and the effect of CSR authenticity and brand trust on brand support. Of the collected data, 392 copies were used for verification and analyzed using a two-step approach and maximum likelihood measure. As a result of the study, it was found that value-driven, stakeholder-driven, and strategic motivations, excluding egoistic motivations, had a positive effect on CSR authenticity and brand trust. In addition, CSR authenticity had a positive effect on brand trust, which was found to support the brand. As a result of comparing Korean and Chinese consumers, it was found that CSR motives in both countries affect authenticity and brand trust, but Chinese consumers showed higher results in more areas than Korean consumers. These results show that K-beauty brands in order to expand the Chinese market, it has implications that it is necessary to understand Chinese consumers and strengthen the CSR motivation strategy they pursue.

Purpose: This study was done to examine the effects of nurses' perception of servant leadership on leader effectiveness, satisfaction and promoting additional effort. The focus was the mediating effects of leader trust and value congruence. Methods: Data were collected from 361 RN-BSN students and nurses participating in nationally attended in-service training programs. Data were analyzed using descriptive statistics and structural analysis with SPSS 17.0 windows program and Amos 7.0. Results: Direct effects of nurses' perception of servant leadership were negative, but mediating effects of trust and value congruency were positively correlated with leader effectiveness, satisfaction and additional effort, that is servant leadership should be effective through mediating factors. Conclusion: The study results indicate that if the middle managers of nurses can build leader trust and value congruency between nurses through servant leadership, leader effectiveness, satisfaction and additional effort on the part of the nurses could result in a positive change in the long term.

블록체인 기술은 '새로운 산업을 만드는 구조'는 아니다. 오히려 과거 인터넷이 도입되면서 사회, 경제 모델 전반이 바뀐 것에 비하면 작은 변화에 가깝다고 할 수 있다. 하지만 블록체인은 높은 보안성과 투명성을 기반으로 기존 산업의 기대 효용을 높여 주고, 다양한 시도를 가능하게 만들어 줄 것이라는 점에서 매우 기대되는 분야이기도 하다. 블록체인은 인터넷 이후의 다른 기술과는 확연히 다르다는 주장을 유심히 살펴볼 필요가 있다. 왜냐하면 블록체인이 인터넷과 우리 사회구조를 어떻게 혁신 시킬 수 있는지, 인터넷 이후의 마케팅 세계가 어떻게 변해왔는지, 소비자는 또 어떻게 변해 왔는지 우리는 쉽게 알 수 있기 때문이다. 이처럼 현재 우리 사회는 "새로운 것을 만들기보다는 효율성과 사회의 신뢰성, 콘텐츠 가치의 투명성을 높여 주는 것이 블록체인의 기술이다"라고 정의할 수 있다. 그렇다면 블록체인 기술의 혁신이 미디어 산업 분야에도 접목되어 새로운 동력으로 작용 할 수 있을 것인가? 이같은 질문과 함께 본 고에서는 블록체인과 콘텐츠 산업, 블록체인과 미디어 서비스 구조, 새로운 서비스 사례 및 기존 스트리밍 서비스, 콘텐츠 제작 및 유통 분야 변화, 그리고 유료 콘텐츠 거래, 디지털 콘텐츠의 효율적인 저작권 관리 분야에서 그 역할과 비중이 어떻게 적용되어 효과가 나타나게 될 것인지에 대해 방송 현업 종사자의 시각에서 살펴보았다. 결국 이러한 신기술을 적극 활용하기 위해서는 블록체인 기술이 갖는 신뢰와 가치라는 근본적인 사항과 미디어업계 종사자들의 긍정적인 인식 변화와 함께 블록체인 미디어 비즈니스 생태계 조성을 위한 연구와 파일럿 적용 등 실험적 여정들이 뒤따라야 할 것이다.

The purpose of this study is to investigate what influence the external variables of the RFID system for eco-friendly agricultural products such as reliability, safety, effectiveness and innovation have on ease and usefulness, perceived value and behavioral intention. An empirical analysis were conducted to the general consumers over the age of 20 years who live in Seoul and Gyeonggi areas having experience of buying eco-friendly agricultural products in department stores, supermarkets and eco-friendly agricultural product specialty stores from November 10 to November 23, 2012, A total of 350 copies of questionnaire were distributed for this research and, excluding partial ones that were too concentrated on one side or found missing values, a total of 305 copies(87.1%) were used as the final statistical analysis data. The result shows that such external variables of the RFID system for eco-friendly agricultural products as liability, safety, effectiveness and innovation are useful enough as a theoretical basis for later study on RFID systems for eco-friendly agricultural products. Also, it reveals that, since all the process from production to sale of agricultural products can be seen, the products are provided safely for consumers, are objectively and rapidly investigated when problems occur, induce a positive attitude with their historical information, and are supplied through systematic management such as consumers' rights to know and choose and recall of unfit products.

Willingness-to-pay (WTP) for pork produced by quality test was determined using a contingent valuation method. Three model studies including a dichotomous-choice and two double dichotomous-choice types were conducted. The respondents in this study appropriately understood the contingent valuation and the suggested price was significant as a characteristic variable. The results imply that there is lower chance to select pork produced by the quality test, as the price difference is greater between conventional and quality-tested pork. WTPs in double and single contingent valuation models were 735 and 547 won/100 g, respectively. WTP was increased with increasing the educational level of respondents. The average WTPs analyzed by convariate were 1,015 won/100 g for double contingent valuation and 580 won/100 g for single contingent valuation. Considering the minimum price of WTP of pork produced by quality test (547.4 won/100 g), the total economic value was estimated to be 5,173,600 million won and per capita customer value was 106,000 won. Therefore, providing an institutional strategy for pork quality test will be beneficial for the consumers.
