In 2008, ETRI developed a new mobile digital ID wallet, in which anyone can store personal information and PKI credential. When the wallet is used, privacy protection is one of the most important problems and personal information should be protected under various usage scenarios such as exchanging sensitive information in on/off-line environments, joining as a new member in the web site, etc. In this paper, we propose a triangular trust management scheme that can effectively manage trustness and also protect sensitive personal information. This scheme relies on three techniques: PKI, reputation and condition (situation context). We implemented prototype of our scheme, and tested it under various scenarios, which showed that the proposed scheme can effectively be used for diverse cases.
Purpose - According to the recently changing consumer smart environment and consumer decision-making process, this study investigates the structural relationship between electronic(online) WOM information characteristics and brand community experience value types on specific brand reliability and brand transformation. In particular, the characteristics of word of mouth information and the experience value of brand community users were divided into detailed fac tors and approached. Methodology - In order to proceed with this study, we review previous studies and setting hypotheses. The hypothesis was verified through a survey that was conducted for the consumers with online consumption activities in less than six months. With reference to previous studies, operational definition was made for the questionnaire design. In order to verify the hypothesis, 282 people were statistically analyzed through the survey This data were used for AMOS for confirm hypothesis established. Results - eWOM information characteristics were classified into usefulness, timeliness and un-bias, and online community experience values were classified into interaction, playfulness, and virtuality. In addition, it is to investigate the relationship between the brand reliability and user's experience value in brad community. The main results are as follows. The first result was that usefulness and un-bias, which are the eWOM information characteristics had a positive effect on forming brand reliability. However, the factor of timeliness did not affect brand reliability. Second, in terms of user experience value and brand reliability in the brand community. It was fo und that experience values such as interaction, playfulness, and vituality all had a positive influence on brand reliability. Third, it was found that brand reliability has a positive influence on the on-line conversion activity of users. Conclusions - Through this study, the field of online consumer behavior research is expanding, and this study suggested that careful management is necessary according to the type or characteristics of eWOM information. Additionally, it presents the importance of the user's empirical value in the brand community influencing brand attitude and reliability. In practice, the implementation of the marketing communication mix in digital marketing has recently been underway to enhance the conversion behavior of users. At this level, it also reveals the preceding factors that increase user conversion behavior.
With the goal of enforcing a municipal police system in a national scale starting from 2021, the proposal for introducing municipal police system is promoted and the private security is spotlighted as the measure for supplementing the issues for municipal police system. To solve this issue, the method of promoting and actively utilizing the private security which served as an assistant for security service into the cooperator for security service is suggested as a practical method. To analyze how police's favorable attitude toward introduction of municipal police system influence on the favorable trust toward private security system, this study conducted a survey on front line police officers and analyzed the collected data through statistical technique. As a result, the police officers favorable to introduction of municipal police system also showed positive attitude toward private security and machine security. However, the survey didn't provide significant result on labor expense. In order for the private security service to be accepted as the cooperator for security service, it is necessary to solve the labor expense issue and strengthen trust on machine security.
With the growing demand for online food delivery (OFD) services via Online to Offline (O2O) platforms, it is required for academic researchers to identify the success factors of OFD businesses. In line with this, this research examines the impact of the core service attributes of a restaurant (hygiene, interactivity, trust,and popularity) on business success in the OFD platform context from the perspective of information asymmetry. Furthermore, the moderating effects of hygiene factor between the core service attributes and the success of restaurants are evaluated. We utilize 1,146 restaurants registered on the largest OFD platform in Korea. The results of this study demonstrate that hygiene (certification), trust (franchise), popularity (favorite) factors have positive impacts on the success of OFD businesses. Moreover, we find that franchise restaurants with high response rates to customer reviews and inquiries achieve higher sales when they have hygiene certifications than those without the certification do. The key findings bear significant contributions to prior literature by empirically substantiating the pivotal role of service quality signals in fostering restaurant success on the OFD platforms. In addition, this study provides business implications for restaurants in O2O platform.
This study is about choice attribution of customers make in food and beverage events. The researcher provided practical plans to uplift food-related enterprises and activate management through surveys and positive analyses, targeting customers who use food services. First of all, all event plans must include customer demands, social changes, special qualities of the business, and market research. Second, low demand season must be customers will be induced to the events. Third, prediction for market variable and solutions must be thoroughly examined and plans should look into the future to maintain a long period of time. Fourth, sufficient communication between planners and employees should be made before the event starts, so that food and beverage businesses can gain trust and quality of event services.Fifth, immaterial service and visible goods/menus in business of food and beverage events must be closely matched. Sixth, menus introducing a variety of merchandise, quality of nutrition and health of the business should be developed. Also, events from countries(regions) should be hold to create a market of cultural exchange. Seventh, for hereafter event plans, feedbacks are needed concerning customers needs and demands through customer care, after the food and beverage events. Eight, faculty management for convenience, kindness, safety, and life preserver accommodations in parking areas must be made, as automobiles are necessaries for people in Mycar era. The ninth, off-line and on-line care through on-line business construction and production of homepage must be done, due to the fact that even the well-made events are bound to fail if they are not delivered to the customers.

Background The Exoscope is a novel high-definition digital camera system. There is limited evidence signifying the use of exoscopic devices in microsurgery. This trial objectively assesses the effects of the use of the Exoscope as an alternative to the standard operating microscope (OM) on the performance of experts in a simulated microvascular anastomosis. Methods Modus V Exoscope and OM were used by expert microsurgeons to perform standardized tasks. Hand-motion analyzer measured the total pathlength (TP), total movements (TM), total time (TT), and quality of end-product anastomosis. A clinical margin of TT was performed to prove non-inferiority. An expert performed consecutive microvascular anastomoses to provide the exoscopic learning curve until reached plateau in TT. Results Ten micro sutures and 10 anastomoses were performed. Analysis demonstrated statistically significant differences in performing micro sutures for TP, TM, and TT. There was statistical significance in TM and TT, however, marginal non-significant difference in TP regarding microvascular anastomoses performance. The intimal suture line analysis demonstrated no statistically significant differences. Non-inferiority results based on clinical inferiority margin (Δ) of TT=10 minutes demonstrated an absolute difference of 0.07 minutes between OM and Exoscope cohorts. A 51%, 58%, and 46% improvement or reduction was achieved in TT, TM, TP, respectively, during the exoscopic microvascular anastomosis learning curve. Conclusions This study demonstrated that experts' Exoscope anastomoses appear non-inferior to the OM anastomoses. Exoscopic microvascular anastomosis was more time consuming but end-product (patency) in not clinically inferior. Experts' "warm-up" learning curve is steep but swift and may prove to reach clinical equality.
Recently, the retro content emerges one of the highest topics in the cultural content area. This retro content has been exponentially expanded through the series of and the success of the series highlights the importance of content that can cause user's emotional experience. Along the line, this research tries to know how the retro contents draw user's emotional experience beyond the role of just user's recall for the past through the Answer me 1994 syndrome. As the result of factorial analysis for the user's emotional experience, five factories were classified: the emotional experiences by music, item, sensory, story and actors exposed in the drama. Also, the five emotional experience factories influence the relations between the viewers and retro content. Specifically, the factories for the emotional experiences are statistically significant to the viewer's satisfaction. They significantly influence the viewer's trust and attachment for the retro content as well. The influence for the emotional experience factors which affect to viewer's satisfaction are music, item, sensory, story, and actors in order. The influence on the trust about the retro content are music, sensory, story, item in order. On the other hand, the emotional experience by actors are not significantly affect to the trust for the retro content. Lastly, The influence for the attachment about the retro content are music, item, actors, sensory, and story in order.
While e-commerce market(B2C) grows rapidly, many experts argue that EC(B2C) transactions have not reached its full potential. A notable difference between online and offline consumer markets that is suppressing the growth of EC(B2C) is the decreased presence of human and social elements in the online shopping environments. Generally online shopping lacks human warmth and sociability. In this study, social presence in online shopping mall was proposed as a substitute for face-to-face social interaction in the traditional commerce and author explored what variables affect social presence(human warmth and sociability) on online shopping malls and how human warmth and sociability can influence on online store loyalty. To achieve research objectives, we reviewed literatures related with marketing, psychology and communication research areas. Based on literature review, we proposed a research model on the online shopping mall. To examine the proposed research model, we gathered data by using a self-report questionnaire. Respondents consists of online shoppers with at least five or more times of purchase experience in online shopping malls. Because social presence is a feeling which needs frequent contacts with malls to experience, respondents must have enough purchase experiences. The empirical results are as follows : First, shopping mall's customization efforts influence perceived social presence on the mall significantly. Second, shopping mall's responsiveness influences perceived social presence significantly. Third, perceived activity of community of online shopping mall influences perceived social presence significantly. Mall managers have to activate their customer community to reinforce social presence, resulting in trust building. Finally, perceived social presence influences trust and enjoyment on the mall significantly. And then trust and enjoyment on the mall affect store loyalty significantly. From these findings it can be inferred that perceived social presence appears determinant which is critical to the formation of core variables(trust and loyalty) in existing online shopping papers.

The authors investigated the existing international fishery relationship in the sea around the Korean Peninsula, and prospected on the reformation of the fishery order which might be followed by mutation of the international political condition and by effectuation of the U.N. Convention on the Law of the Sea in the future. It can be explained that the existing international fishery order in this sea has been constituted on the basis of restricting Japanese indiscriminate fishery expansion. But. when the South Korea and China proclaim the 200-mile EEZ in the future, a considerable part of existing fishery agreements will forfeit the role as general norms of the international fishery relationship. Accordingly a counterplan against the revision or abrogation of the Korea-Japan Fishery Agreement must be considered. And also a rational fishery relationship between Korea and China, as confronting countries, must be organized. The South-North Korea fishery relationship must be settled on the basis of co-operation. trust, and common interest. For this purpose, a political discussion on the establishment of the joint fishery zone around the military demarcation line and on the conservation for the fishery resources must be begun in earnest.
