  • Social media users are an important part of our lives as they spend a lot of time and actively use them. However, it is known that there are many users who feel the psychological stress of SNS stress or fall into addiction due to SNS use. SNS stress negatively affects not only the user's mind but also the body. This study investigates the associations between SNS stress and addiction. To test the hypotheses, the study performed structural equation modeling using Amos. We collected 210 data from SNS users. The empirical results showed that SNS overuse had a significant effect on SNS stress. Second, SNS stress had a significant relationship with SNS addiction. Third, it was found that SNS overuse did not directly affect SNS addiction. This study suggests that it is necessary to recognize the importance of the relationship between SNS addiction and SNS stress.

  • Jinhae Bay is used as a major typhoon shelter in the southeastern region of Korea. However, when a typhoon strikes, the Jinhae Bay is facing the possibility of marine accidents caused by dragging anchors and the increased number of ships. This paper suggested ways to safely and efficiently manage the port of Jinhae Bay when a typhoon strikes from Vessel traffic service operators in the sea, derived relative importance by conducting an Analytic Hierarchy Process assessment to ship operators, and suggested safety measures reflecting manager and user opinions. In order to select safety measures factors for the AHP survey, VTS operators analyzed the evaluation of measures when a typhoon strikes in Jinhae Bay. As a result of conducting a survey based on the selected safety measure factors, it was found that ship operators consider the safety of ships more than twice as important as efficient management, and comprehensively consider them in the order of management of evacuated ships, management of anchorage area, management of evacuation information, preparation regulations and guidelines, improvement of system equipment, education, publicity, and notification activities. Through the measures and relative importance identified in this paper, it is believed that Jinhae Bay can serve as the basis for safely and efficiently managing typhoon shelters.

  • This study examines the economic use value of Discover, an access service of research papers and a subsystem of the National Open Access Platform (AccessON). Based on previous literature on scholarly communications and in-depth interviews with 14 academic and industrial researchers, the service value of Discover was identified as the value of time savings. Administering a survey with 1,313 researchers, the following empirical data required for estimation were obtained: for an average Korean researcher, s/he publishes 2.84 papers per year and takes 30.13 minutes in searching and using one relevant research paper. Discover was found to save 5.64 minutes per paper, saving a total of 225 minutes and KRW 99,384 per researcher per year. Finally, a total economic value of Discover was estimated as KRW 82 billion for the entire 8-year business period. An additional value of KRW 11.3 billion was estimated with the legalization of mandatory deposit of OA research papers. The study demonstrates a sufficient economic value of the national OA platform project, and positive economic impact of the OA legalization, futher offering important domestic data for future research on economic value of scholarly communications.

  • The purpose of this study is to identify the topics of research related to the concepts of literacy in the field of Library and Information Science which is related to user education in libraries. Data were collected from the WoS and KCI databases, and complementary keyword analysis and topic modeling analysis techniques were used to identify topics of literature-related research articles in the field of Library and Information Science. Findings presented that there was a difference in keywords and topics between the two databases. Literacy-related topics identified from the KCI database were classified into three groups through topic modeling. Also, it was analyzed that there is a difference between the overall literacy-related research trend, the timing of the surge in research volume, and key frequent keywords in the Library and Information Science field confirmed in the study. In particular, in the study of literacy in all fields, a number of words such as 'literacy', 'education', 'media', and 'digital' were derived. However, in literature research in the field of Library and Information Science, keywords such as 'information utilization ability' and 'school library' appeared. Based on this, it was concluded that research on the ability to develop an evaluative eye for information is needed in line with today's information environment, where information is rapidly increasing in Korea in the future.

  • In this study, a survey of public library librarians was conducted to examine the current librarian's job status by conducting a survey on the library's environment, such as the size of books, number of employees, and operating subjects. As a result of the study, it was found that based on the current job content and recognition, librarians are mainly working in the order of operating reading culture programs, planning reading culture programs, and user information services. In addition, it can be seen that librarians highly value the importance of their respective duties, and in the case of labor intensity, more than half of them recognize that the current labor intensity is high. Among the detailed competency units corresponding to each task in the future, more appropriate competency unit elements should be considered in consideration of the essential competency, additional supplementation, and lower factors through this study. In addition, the higher the number and experience of regular workers in the library, the higher the degree of librarian certification, and the higher the current position, the higher the importance, difficulty, and expertise of the current work, so it is expected that the library should continue to build experience in the future.

  • The purpose of this study is to propose a scholarly paper recommendation system based on metadata attribute similarity with excellent performance. This study suggests a scholarly paper recommendation method that combines techniques from two sub-fields of Library and Information Science, namely metadata use in Information Organization and co-citation analysis, author bibliographic coupling, co-occurrence frequency, and cosine similarity in Bibliometrics. To conduct experiments, a total of 9,643 paper metadata related to "inequality" and "divide" were collected and refined to derive relative coordinate values between author, keyword, and title attributes using cosine similarity. The study then conducted experiments to select weight conditions and dimension numbers that resulted in a good performance. The results were presented and evaluated by users, and based on this, the study conducted discussions centered on the research questions through reference node and recommendation combination characteristic analysis, conjoint analysis, and results from comparative analysis. Overall, the study showed that the performance was excellent when author-related attributes were used alone or in combination with title-related attributes. If the technique proposed in this study is utilized and a wide range of samples are secured, it could help improve the performance of recommendation techniques not only in the field of literature recommendation in information services but also in various other fields in society.

  • The ultimate goal of classification systems is to provide tools for information management and services through collocation of information objects in similar topics. The National Research Council for Economics, Humanities, and Social Sciences(NRCS) aims to organize the research products from 23 research institutes. To manage and organize the research products effectively, the standard classification system has been developed in conjunction of users' survey and the Business Reference Model(BRM). Although the standard classification system consists of users' perspectives and the aspects of organizational functions, there are limits to apply the system into classification practices. In this study, the proposed hybrid approach is to combine a clustering approach with 1,884 keywords from the titles of research products between 2007 and 2008. The clustering approach is performed in a heuristic way according to the KDC due to the lack of digital full texts of research products. The results of this study proposed a revised standard classification system for NRCS with 16 headings and 90 sub-headings. The revised standard classification system will play an important role in managing research products effectively.

  • The purpose of this study was to evaluate the status of oral health care in dementia patients living in long-term care facilities and to investigate the effects of this on swallowing function and swallowing-quality of life. The subjects were 60 demented patients who were admitted to long-term care facilities in Gwangju and Jeonnam provinces. Their Oral Health Assessment Tool(OHAT), Clinical Dysphagia Scale(CDS), and Oral Health Impact Profile 14(OHIP-14) were measured. The results of this study were as follows: First, the effect of oral health care on dentition patients using long-term care facilities on swallowing function and swallowing-quality of life was significantly different according to oral care score (p<.05)(p<.01). Second, the relationship between oral health care and swallowing function of dementia patients and swallowing-quality of life. was examined. As a result, oral health care of dementia patients was affected by swallowing function (r=.405, p<.01) the swallowing-quality of life (r=.462, p<.01) and swallowing function were significantly correlated with swallowing-quality of life (r=.351, p<.01). Therefore, the oral health care of users of long-term care facilities was closely related to swallowing function and swallowing-quality of life.

  • This study was conducted to understand current management status of 'day and night care' facilities and to explore the related factors with rates of operation of them. The nationwide mailing survey was conducted with structured questionnaires from July, 14, 2010 to July, 28, 2010. The subjects were 277 facilities (response rate 24.5%). Regarding the types of operating, 79.1% of faculties was run by cooperation, and 17.8% and 3.6% for individuals and national/public institutes respectively. The average of operation rate was 70.15%. National/public institutes showed higher in the rate of operation(79.08%) than 72.49% of cooperations and 57.78% of individuals. The number of manpower was not nearly different by the types of operating bodies, but the number of nurse was significantly different among them. The national/public institutions had 1.07 nurses while individual institutions have only 0.08. We found that facilities run by national/public institutes and founded before 2008 years showed higher rate of operation. In case of providing regular monitoring and evaluation services, and music program for patients showed higher rate of operation. In addition, the number of managers, social workers, and nurses increase the rate of operation. We suggest that quality management and monitoring program for the facilities which run by individuals or established after 2008 years would be developed. We also call for development of programs for facilitating utilization of 'day and night care' facilities such as expanding the family support.
