In modern times, many IoT products are being used as all things and devices are connected to the Internet and IoT products become easily accessible through the network. For the convenience of users, IoT products can be remotely operated automatically without manual operation. Various research and development are underway to improve the convenience of users by using IoT products. However, since only the convenience of the users is pursued, in terms of security, there is a serious problem that exposes the user's personal information. This paper has proposed a method to apply $moir{\acute{e}}$ technology to IoT products in order to improve the performance of security, and a method to increase the safety of IoT products using user face authentication based on shadow $moir{\acute{e}}$ as a $moir{\acute{e}}$ phenomenon method, and the projection $moir{\acute{e}}$. When comparing the existing IoT products and IoT products applied with $moir{\acute{e}}$ technology, IoT products applied with $moir{\acute{e}}$ technology are safer in terms of security.

The rapid growth of the Internet has increased the amount of transmission of personally identifiable information. At the same time, with new Internet related technologies, organizations are trying to collect and access more personal information than before, which in turn makes individuals concern more about their information privacy. For their successful businesses, organizations have tried to alleviate these concerns in two ways: (1) by offering privacy policies that promise certain level of privacy protection; (2) by offering benefits such as financial gains or convenience. In this paper, we interpret these actions in the context of the information processing theory of motivation. This paper follows Hann et al.(2007)'s methods to analyze Internet users privacy concerns in Korea and tries to compare the findings. Our research objectives are as follows: First, we analyze privacy concern mitigation strategies in the framework of the expectancy theory of motivation. Subsequently, we show how the expectancy theory based framework is linked o the conjoint analysis. We empirically validate the predictions that the means to mitigate privacy concerns are associated with positive valences resulting in an increase in motivational score. In order to accommodate real-life contexts, we investigate these means in trade-off situation, where an organization may only be able to offer partially complete privacy protection and/or promotions and/or convenience, While privacy protection (secondary use, improper access) are associated with positive valences, we also find that financial gains can significantly increase the individuals' motivational score of a website in Korea. One important implication of this empirical analysis is that organizations may possess means to actively manage the privacy concerns of Internet users. Our findings show that privacy policies are valued by users in Korea just as in the US or Singapore. Hence, organizations can capitalize on this, by stating their privacy policy more prominently. Also organizations would better think of strategies or means that may increase online users' willingness to provide personal information. Since financial incentives also significantly increase the individuals' motivational score of website participation, we can quantify the value of website privacy protection in terms of monetary gains. We find that Korean Internet users value the total privacy protection (protection against errors, improper access, and secondary use of personal information) as worthy as KW 25,550, which is about US 28. Having done this conjoint analysis, we next adopt cluster analysis methodology. We identify two distinct segments of Korea's internet users-privacy guardians and information sellers, and convenience seekers. The immediate implication of our study is that firms with online presence must differentiate their services to serve these distinct segments to best meet the needs of segments with differing trade-offs between money and privacy concerns. Information sellers are distinguished from privacy guardians by prior experience of information provision, To the extent that businesses cannot observe an individual's prior experience, they must use indirect methods to induce segmentation by self-selection as suggested in classic economics literature of price discrimination, Businesses could use monetary rewards to attract information sellers to provide personal information. One step forward from the societal trends that emphasize the need of legal protection of information privacy, our study wants to encourage organizations and related authorities to have the viewpoints to consider both importance of privacy protection and the necessity of information trade for the growth of e-commerce.

This paper addresses the issues of affecting factors to measure the satisfaction degree in PC communication utilizations. In order to develope an optimal model, we study appropriate affecting factors in PC communication utilizations through the focus group interviews with student users, and surveys the satisfaction levels that users have felt in services. Based on the optimal regression model, we suggest an appropriate satisfaction model in PC communication utilizations. That model shows that most users are interested in the A/S area for use. A/S factor is the most powerful one to the satisfaction model. Second one is usefulness, next is DB quality. But service-ability factor and convenience one are negative ones. Most users think that their factors are in the way of fluent communication. So to keep the competitiveness in the PC communication utilizations, the negative factors should be amended as soon as possible.

In the Web 2.0, besides more gaining information on the web, the number of web sites that take advantage of RSS increases explosively. Commonly each users search RSS channels through the web search engine before registering RSS channel's url to the RSS reader. Users judge whether the site is RSS channel or not and register an RSS channel's url through theirs interests. Because accomplished by users themselves, those processes conflict to user's convenience and quick consumption of information. Techniques of current search engines can't provide users with reliable RSS feed information as search results. In this paper, we analysis appropriateness of current search engines' techniques that offer users RSS feed search service and discuss their limitations. Also, we make up RSS feed database through classification of RSS tag being possible to search RSS feed information effectively and apply update rate of each RSS channel's feed to ranking algorithm providing more reliable search results.

The purpose of this study were (1) to analyze the current fashion web-sites on the internet, which were increasing rapidly in number, (2) to find out the users purchase experiences of fashion products at internet shopping malls and satisfaction level on the information provided by the fashion sites. The questionnaire was administered to 332 women & men and data were analyzed by frequency, mean, standard deviation, factor analysis, reliability analysis, ANOVA and t-test. The results of this study were as follows. The factors on the satisfaction of information fashion web-sites categorized as 5 areas: Economy$.$Convenience, Aesthetics $.$Recreation, Variety $.$Interests, Up-to dateness $.$Specialization, and Reliability$.$ Precision. On the factor of Economy$.$Convenience, the users who had more frequent access and who were in their 20’s expressed the higher level satisfaction. On the factor of Aesthetics$.$Recreation, the users who had longer periods of time of use, who had lower level of internet shopping mall involvement, and students appeared to be more satisfied. On the factor of Variety$.$Interests, the users marking higher level of satisfaction were those who had higher frequency of uses, who had shorter period of time of use, who had lower level of internet shopping mall involvement and were students. On the factor of Up-to-dateness$.$Specialization, higher level of satisfaction was shown among the users who had shorter period of time of use, who had higher frequency of uses, who were in their 20’s and who were students. There was no significant differences according to Reliability & Precision factor.

Purpose: The purpose of this study was to examine effectiveness and usefulness of Information Communication Technology (ICT) in communication between physician and visiting nurses who provide visiting nursing services under long-term care insurance. Methods: Structured questionnaires were used to measure usefulness and satisfaction of the system, both accessibility and convenience to visiting nurses (31 people) and users (182 people). Results: From the user perspective, accessibility and convenience in terms of service users were both satisfactory as shown by users' percentage. No statistically significant difference was found for satisfaction between before and after using the system. The usefulness of the system for visiting nurses was satisfactory for most the nurses. Also most nurses answered that the system is needed and is very useful. Most of the participants (both visiting nurse and service users) were satisfied with use of the ICT system. However, there was no statistically significant difference in satisfaction between the pre and post service because the service provision period was too short (three months). Conclusion: The consensus from both users and service providers is that an ICT based visiting nursing system needs to be introduced but a more user - friendly environment for system development will be needed.

The purpose of this research is to suggest the direction of the domestic convenience store platform in the aging society and the fourth industrial revolution. Recently, convenience stores have been providing various lifestyle platforms by seeking new growth engines based on the reputation that the number of convenience stores has reached the saturation. In order to present the direction of development, It conducted a questionnaire survey of 78 people from domestic teenagers to 60s or older and case study of domestic and overseas convenience store platforms. Through this survey, it was found that convenience stores in Korea provide users with a convenient lifestyle platform, but the service for the elderly was found to be in shortage compared to other countries. Convenience stores should offer lifestyle platform services for the elderly, as they provide lifestyle platform services for people in 20s and 30s. This will make the convenience store a competitive lifestyle platform service in the 4th industrial revolution. In addition, it is necessary to continuously study the CVS living platform service according to the changing social phenomenon in the future.

A coastal ferries, which serve as a mode between mainland and offshore islands, are frequently used by islanders and travelers visiting islands. Therefore, it is located in a place with good accessibility to the downtown so that users can use it conveniently. However, research on the built environment and walking environment of coastal ferry terminals has not been conducted to ensure that elderly islanders and general travelers can use comfortably the coastal ferry terminal. In this study, with a focus on the coastal ferry terminal space, the walking section was set as 1)the accessibility of the coastal ferry terminal, 2)the built environment for using the coastal ferry terminal, and 3)walking environment in the ferry boarding and disembarkation at the coastal ferry terminal, and 4, 5)walking environment in the ferry. An evaluation tool was developed to measure the walking environment for each walking section, and the importance and satisfaction of users were analyzed using the IPA for the Yeosu Coastal Ferry Terminal. As a result, in the process of approaching the ferry terminal, 'convenience of using public transportation by foot' and 'convenience of using signposts guiding the location and direction of the ferry terminal' were investigated as concentrated areas. On the other hand, the built environment inside the ferry terminal and the walking environment showed that the satisfaction of the users was high. Regarding the walking environment from the ferry terminal to the ferry, the 'surface walking environment of the walking path', 'convenience of walking with luggage', 'convenience of walking in the slope section', and 'convenience of walking in the ferry ramp section' showed low satisfaction. This study can be used as basic data for improving the facilities and walking environment of Yeosu Coastal Ferry Terminal and is expected to be used as data for comparative research with other coastal ferry terminals.

This study is aimed at grasping improvement factors of Cheonho Park, Gandaemae Park and Hunlyunwon Park as barrier free friendly parks. For this study, current status of parks, users' state and satisfaction were analyzed in October, 2014 and September, 2015. To detect current status, period of designing, whole size, facility pavement green space area, and main spaces were examined. As for BF status, mediation facilities, leading and guidance facilities, convenient facilities and BF pedestrial passage were analyzed. Also, It examined user behavior and satisfaction by accessibility, convenience and safety items. As a result of status analysis, three parks were designed in 1997~1998. The size of parks were $15,180m^2{\sim}26,697m^2$. As for mediation facilities, the slopes of walking-passage in Cheonho Park and Gandaemae Park were flat. The rate of leading-guidance facilities was 72.7%~93.4%. In the three parks, the effective width of safe pedestrian space within BF pedestrial passages was more than 1.8m. In Cheonho Park and Gandaemae Park, more than 50% of soil and urethane were used as paving materials. Users were the most satisfied with accessibilities in Cheonho Park due to flat-typed walking passages. In convenience, when it comes to using benches and pergolas, it showed significantly different satisfaction in every park. In safety, there were also considerable difference in every park. Overall, it was analysed that the satisfaction with information for safety and facilities was significantly low. Against this backdrop, this study suggests three considerations to recreate parks as barrier free friendly parks. 1) Flat-typed walking passages and enough parking areas near parks should be constructed. 2) Additional rest furniture for convenience should be installed and complemented. 3) Walking oriented-spatial safe facilities for safety should be differently supplemented.

Theoretically, both of fund transfer and balance inquiry which are typical Internet banking services are influenced by the beliefs on the use of Internet banking such as perceived risk and convenience, which have been shown as in the other studies. However, the use of fund transfer can be more sensitive than that of balance inquiry by the beliefs on Internet banking use since the former is not only more risk involved but also more complicated in using than the latter. The objective of this study is to analyze the relationship between the use of two Internet banking services-fund transfer and balance inquiry-and the beliefs on Internet banking use-security risk, convenience and social Influence. For this purpose, we provide the research model for explaining the difference between balance inquiry and fund transfer in the degree of influencing by security risk, convenience and social influence and test it empirically by collecting data from surveying for 206 internet banking users. In result, we show validity of the suggested model by Partial Least Square(PLS) approach.
