This study, based on the assumption that self-rated health status affects the use of health care utilization, aims to comprehend self-rated health status, as well as the differences in medical facility use depending on self-rated health status, and analyze according to chronic diseases to use it as the basis of a practical guide development for chronic disease patients' use of medical facilities. Used representative Korean Longitudinal Study of Ageing data to analyze 7,486 participants. There is a difference in Chronic disease patients' use of health care utilization depending on self-rated health, and this difference was the most apparent in Oriental healthcare service and dental treatment use. This study was unable to control all confounding variables affecting medical service use, so we want this studied to be used to assist future studies.

Business Intelligence (BI) system is a strategic tool that presents an analytical perspective about business and external environments. Even though its strategic value was well known, users often avoid using it or adopt it ceremonially. In fact, over 50 per cent of BI projects worldwide are reported to end in failure. Such an unexpectedly lower success rate has been a key issue in BI studies. In order to enhance a proper use of information systems, MIS field provided a number of theoretical constructs. One example is Goodhue & Thompson's Task-Technology Fit (TTF). In addition, internalization, the degree to which people make their own effort to modify behavior, was recently suggested as another important determinant of use. Though in MIS community both TTF and internalization proved to be a key determinant of system use, there has been not much study aiming to discover antecedents influencing these constructs. In this study we assert that user participation should be highlighted in BI projects. Especially, we emphasize user participation at the phase of feasibility study that is mainly conducted to determine whether a BI system is essentially necessary and practicable. Our research model employs participative feasibility study as a major antecedent for TTF and internalization that consequently will lead to user satisfaction and actual use. This model was empirically tested on 121 BI system users. The result shows that user participation in feasibility study is positively associated with TTF and internalization, each being related to user satisfaction and system use. It implies that, if an organization has BI users get involved in strategic feasibility study phase, the BI system would turn out to fit users' tasks and, furthermore, users would put more efforts spontaneously in order to use it properly.

Recently, delivery app services based on the O2O platform are increasing rapidly. Accordingly, various studies on O2O service have been conducted. Most of the studies are on consumer behavior in O2O services, and few studies on platform vendors have been conducted. Therefore, this study empirically analyzed the factors affecting the vender's intention to continuous use in the O2O delivery app platform service. Based on prior researches, we set the quality characteristics and network characteristics of the O2O platform as independent variables. The quality characteristics of the O2O platform consisted of system quality, information quality, and service quality, and the O2O platform network characteristics consisted of network externality and platform reputation. Perceived value and switching cost were set as mediated variables, and vender's intention to continuous use was set as dependent variables. For empirical analysis, we conducted a survey targeting vendors of O2O delivery app platform service, and conducted frequency analysis, factor analysis, reliability analysis, and regression analysis. As a result of the analysis, the quality characteristics of the O2O platform, such as system quality, information quality, service quality, and O2O platform network characteristics, showed that network externality and platform reputation had a positive effect on perceived value. The perceived value was found to have a positive effect on the switching cost and the intention to continuous use, and the switching cost was found to mediate the perceived value and the intention to continuous use. This study can contribute to the establishment of platform operation strategy as an empirical analysis on the factors that influence the intention of O2O platform vendors to use the platform continuously.

Rapid change in information use environments that corresponds with the development of new technologies requires a new perspective in examining information source uses and information services. As understanding information seeking behaviors is an essential element for improving information services, the changing information seeking behaviors should be examined in a timely manner. While several prior studies focus on this topic, few studies deal with medical doctors' information seeking behaviors especially focusing on information seeking in both medical practices and research. Thus, this study aims to explore the information seeking behaviors of medical doctors who are both medical practitioners and researchers. Data were obtained by open-ended and semi-structured in-depth interviews during one month from April to May, 2009. The interview-question topics ranged from research contexts, medical-practice-related information seeking behaviors, favorable information sources, and information search process and satisfaction. Findings include that, for research purpose, digital journal articles accessed through the PubMed were more favorable sources while, for practice purpose, printed textbooks were preferred. Overall, the most-frequently-used sources were PubMed and articles because medical doctors regard the reliability and authority very highly.

Existing data structures for non-manifold solid modelers use basic dat entities, such as vertex, edge, loop, face, shell, and region to find adjacency relationships. But, no one clearly identified what additional types of data entitles are necessary to represent incidence relationships. In this paper, we classified the boundary information of vertex, edge, face , and region from the 3-D space view. As the results we can clearly define the boundary information required for adjacency relationships. The existing B-rep data structures for solid modeler are compared whether they have the required boundary information.

Using data from the 2007 SCF, this study examined the use of information source for investment decisions of elderly consumers. The results indicated that many elderly consumers (about 88%) involved savings /investment decisions. The elderly used 'Experts' (39.48%) as a major information source for their investment decisions, followed by 'Friends' (24.18%). The results of the multinomial logit analysis suggested that the perceived value, the cost for search, knowledge, risk and some of the demographic factors were significantly related to the choice of the information sources for investments by elderly consumers.

Science and technology information data is steadily increasing not only in Korea but also around the world. At present, dozens of documents are produced and distributed every day regardless of field, and researchers are increasingly demanding to use this information effectively to support research activities that are valuable and useful for human life. In the past, researchers are moving away from searching for necessary information, and now they are changing to services that connect data and data, find high value-added information that can be used, and present it to researchers. In this study, we analyze literature data created by Korean researchers from domestic and foreign scientific and technological information data, find use cases, and provide information to help researchers.

Recently, the popularity of smartphones has led to a dramatic increase in the frequency of use of App(Application) services. LBS (Location-Based Service) App service adopts various methods such as push marketing and useful information by region through providing location-based service based on the location of the consumer. In particular, an enterprise or an App management company can provide necessary information to the consumer through the necessary information among the customer related knowledge information obtained by utilizing the location information of the consumer in real time. Nevertheless, since LBS is a service that can be performed only when the company obtains consent to provide location information voluntarily by the consumer, there is a case of privacy infringement due to consumers' use of personal information. The purpose of this study is to identify the characteristics of privacy related variables and the knowledge structure for consumer value formation based on the theory of privacy calculation. We also compared the characteristics of Korea with those of China in privacy issue. As a result of the analysis, it was confirmed that factors such as information utilization ability and information control ability were influential as a key factor of privacy calculation. In addition, perceived value influences the reputation of the LBS App service.
