With the explosive increase in data, the 'big data era' has arrived, focusing on deriving new values and insights through data. With the development of data analysis technology, the importance of data analysis and utilization in the field of diagnosis and treatment as well as prevention is expanding, while the use of big data is emerging in the healthcare field. Moreover, as the three data-related laws (Personal Information Protection Act, Information and Communication Network Act, and Credit Information Act) were passed in January 2020, it became possible to use a wide range of big data through pseudonym information. However, the use of healthcare big data is still struggling due to various policies and regulations, inconsistent data quality, and the absence of specialized personnel. Therefore, in this study, examines the current state of use of big data in the healthcare field, and analyzes the challenges, overseas cases, plans, and expected effects for activation of healthcare big data.

POI refers to the point of Interest in Location-Based Social Networks (LBSNs). With the rapid development of mobile devices, GPS, and the Web (web2.0 and 3.0), LBSNs have attracted many users to share their information, physical location (real-time location), and interesting places. The tremendous demand of the user in LBSNs leads the recommendation systems (RSs) to become more widespread attention. Recommendation systems assist users in discovering interesting local attractions or facilities and help social network service (SNS) providers based on user locations. Therefore, it plays a vital role in LBSNs, namely POI recommendation system. In the machine learning model, most of the training data are stored in the centralized data storage, so information that belongs to the user will store in the centralized storage, and users may face privacy issues. Moreover, sharing the information may have safety concerns because of uploading or sharing their real-time location with others through social network media. According to the privacy concern issue, the paper proposes a recommendation model to prevent user privacy and eliminate traditional RS problems such as cold-start and data sparsity.

In recent years, the privacy concern for mobile consumers is emerging as the use of mobile application(apps) is growing according to the rapid spread of mobile devices such as smart phones and tablet PCs. To improve privacy protections in the mobile communications and apps, overseas organizations are announcing guidelines and/or checklists for stake holders. Although personal information protection guidelines for application developers have been prepared in the country, efforts to improve consumer privacy capability is insufficient. Thus, in this paper we first scope the app privacy related guidelines in both domestic and foreign affairs, then present the risk factors of privacy invasion by the stage of mobile application use based on the "Privacy Protection Act", offering privacy checklists for consumers. This checklist will enhance the self-management capability of consumer privacy and create virtuous cycle in the mobile ecosystem.

Objectives: We surveyed the awareness and current status of using fumigant carbon disulfide for exterminate Curculio sikkimensis among chestnut farmers in Chungnam Province to suggest directions for health education and public relations. Methods: We designed questionnaires to evaluate recognition of fumigant carbon disulfide. We conducted a questionnaire survey to assess recognition and recognition level of fumigant carbon disulfide by the study variables. Results: The recognition status for fumigant carbon disulfide was 74.5%, but the recognition level was low (know well 27.5%). The path of recognition was 45.1% and 15.7% for neighbor and rural technology center, respectively. The recognition status for warning label of fumigant carbon disulfide was 52.9%. Recognition for warning label of fumigant carbon disulfide was tended to increase with high educational attainment, bigger owning land area. Recognition on the content of warning label were 29.4%, 27.5%, 21.6%, and 21.6% for inflammability, toxicity, hazard, and explosiveness, respectively. Using personal protection equipment was tended to increase with the high status of awareness on fumigant carbon disulfide. Conclusions: Health education programs for using fumigant carbon disulfide are needed for chestnut farmers. In addition, publicity information activities about prevention and protection of carbon disulfide poisoning are needed for high risk farmers.

Thanks to popularization of smart phone, mobile payment market is growing rapidly. As the obligatory use of digital certificate is abolished, easy-to-use payment that can settle with only password is being launched one after another. But its spreading speed is not fast highly. Because of concern about personal information leakage and security, unchangeability of payment habit, insufficiency of consumer protection, inadequacy of payment infrastructure and all sorts of regulations, easy-to-use payment is not activated. Recently global IT companys are entering mobile payment market competitively. It is because the sense of crisis that their survival can be dangerous from now on if they get left behind Fintech innovation and the mentality that they try to take the leadership of mobile payment market process. In this situation, the thorough preparation and a lot of effort are required to promote our autonomous easy-to-use payment growth without dependance on foreign country's. In this paper, the problems of local mobile easy-to-use payment are addressed in depth and the activation measures such as flexible and discriminative security, construction of customer protection system, law system maintenance, service differentiation are proposed.

This study examined the trends and practices of disaster welfare in Japan, particularly with the point of view of the community response. This study summarized the experiences and implications of Japan's disaster welfare. First, it is necessary to establish a foundation and linkage of support networks. In case of a disaster, the linkages among administrations, social work institutions, and community residents are required to understand the accurate situation and needs, and to develop resources. In particular, the constitution of DWAT was submitted for initial intervention. Second, the establishment of a manpower dispatching system is needed for emergency situations. In addition, the methods to cover the entire areas by system are needed. Third, the intervention of psychological treatment was shown have a low agreement rate among specialists. Fourth, it is necessary to have guidelines so that privacy protection is compatible with disaster support in a disaster welfare practice process.

As the number of smartphone users increases, vulnerability to privacy protection is increasing. This is because personal information is stored on various servers connected to the Internet and the user is authenticated using the same ID and password. Authentication methods such as OTP, FIDO, and PIN codes have been introduced to solve traditional authentication methods, but their use is limited for authentication that requires sharing with other users. In this paper, we propose the authentication method that is needed for the management of shared information such as hospitals and corporations. The proposed algorithm is an algorithm that can authenticate users in the same place in real time using smart phone IMEI, QR code, BLE, push message. We propose an authentication algorithm that can perform user authentication through mutual cooperation using a smart phone and can cancel realtime authentication. And we designed and implemented a mutual authentication system using proposed algorithm.

In this knowledge-based society of this age, librarianship takes a professional position and requires essential principles of ethics that has to be observed. Therefore, library associations and professional communities all over the world have released criteria and code of ethics to make their professional positions to keep. This research investigated and analyzed the codes of ethics for librarians in United States, Great Britain, Japan, and South Korea which are based on the mission of each library of each country. Based on these analysis and comparison, this research proposed more advanced codes of ethics for South Korea. The proposed model of codes of ethics consists of two parts: ethics for information and ethics for professional positions. The ethics for information contains six essential elements: equal access and services for information, denial of inspection, protection of privacy, neutralization of librarian, and security of intellectual freedom. The ethics for professional positions consists of 8 essential aspects: exclusion of personal benefit, continuous efforts for developing knowledge, keep the professional position, conflicts between professional task and organization, relationship with co-workers, ensure the conditions of rights and welfare for employees, cooperations among libraries, and contribution for creation of new culture.
