Nowadays as video services grow rapidly, it is important for the service providers to provide customized services. Video ranking plays a key role for the service providers to attract the subscribers. In this paper we propose a weekly video ranking mechanism based on the quantified user engagement. The traditional QoE ranking mechanism is relatively subjective and usually is accomplished by grading, while QoS is relatively objective and is accomplished by analyzing the quality metrics. The goal of this paper is to establish a ranking mechanism which combines the both advantages of QoS and QoE according to the third-party data collection platform. We use data mining method to classify and analyze the collected data. In order to apply into the actual situation, we first group the videos and then use the regression tree and the decision tree (CART) to narrow down the number of them to a reasonable scale. After that we introduce the analytic hierarchy process (AHP) model and use Elo rating system to improve the fairness of our system. Questionnaire results verify that the proposed solution not only simplifies the computation but also increases the credibility of the system.

Archives should promote services to users using various outreach service methods. Although the archives' tour program is one of the effective means of services, there has been few studies on the archival tour program. This study investigated archival tour programs and tried to suggest a desirable tour program, with the Korean Presidential Archives as a case. For this study, four U.S. Presidential Libraries' tour programs were investigated and analyzed. Also, tour programs offered in similar organizations in Korea, such as Kim Daejung Library, Diplomatic Archives of the Ministry of Foreign Affairs, and National Library of Korea, were analyzed. Current tour programs offered by the Korean Presidential Archives were also analyzed and some limitations were identified. Based on the characteristics of the Korean Presidential Archives, which will be moved to independent building in Sejong City soon, desirable direction to organize tour programs for various user groups were suggested.

With the improvement of the Information Technology and the change of the business environment, the dependency of business on the Information Technology shows sharply increase. The Information Technology, however, is centered on the support of the technology viewpoint and thus the influence and effect of Information Technology on the business is hardly analyzed. The information system, therefore, requires not only technology-centric support management but service-oriented and systematic introduction of Information Technology Service Management(ITSM). The domestic ITSM market is currently expanding into variety of industries like finance, telecommunication, manufacturing and public service and at the same time the consequent reconstruction process of information system is continuously under way so as to qualify for the ISO 20000 certification. Especially the public organizations rapidly adopt the ITSM, in order to improve the quality of public service together with a goal of realizing the electronic government and of managerial innovation. The existing ITSM still, however, shows the tendency of depending only on the system construction and the management on the visible requirements whereas the overall process is not likely being improved. Hence, this study suggests, focusing on the life cycle of service, the model of ITSM based on Information Technology Infrastructure Library(ITIL) v3 which is appropriate for the public service. We expect, as stated in this study, that our ITSM model shall be widely accepted to the public agencies who promote the advance campaign by setting up the ITSM or reconstructing the existing process.

This study investigated users' information seeking behaviors associated with their perceptions of uncertainty. For this study, the data was collected from an user group, who conducted information searches in the field of history, using the KERIS Edunet system and it was analyzed through the comparative analysis of the grounded theory. The results presented users' uncertainty in the following stages: the identification of information needs, the selection of an information system, the selection of search terms, the actual use of the system, and the evaluation of search results. Major implications pertain to the enhancement of the Edunet system and related services. The former includes the improvement of the retrieval mechanisms related to the search and display interfaces. The latter emphasizes the consideration of the origin of uncertainty in the process of the services. In other words, the study suggested to consider the inadequacy of the system functions, the insufficiency of search experiences and the lack of such abilities of particular users.

The study aimed to investigate the motivation and user satisfaction of medical school graduate students using specific academic information sites, and examines the effect of usage motivation factors on user satisfaction. This study was conducted from September 10, 2018 to September 21, 2018 by a large medical school graduate student in Seoul, and analyzed 135 valid responses. According to the analysis, the degree of reliability and interactivity of PubMed is higher than that of Google Scholar in medical school graduate students' use of academic information sites. It was found to have a significant effect on user satisfaction of academic information sites. In particular, convenience has the greatest influence on users' choice of academic information sites. The results of the study are of theoretical implications in that the discussion of academic information services through web sites is explained in terms of use and satisfaction in the context of medical information. On the other hand, specific research results provide practical implications for improving the services of medical-related academic search engines.

This research proposed an approach for interlinking bibliographic data used in the existing multicultural institutions in order to support information services of multicultural institutions. It constructed a set of linkage properties that can link the FRBR-based BIBFRAME structure with the existing metadata standards currently adopted in multicultural institutions, including MODS, EAD, and CDWA. As a result, the descriptive elements for the Work level, Instance level, Item level, statement of responsibility, subjects were established in the BIBFRAME syntax. A total of 19 upper level elements, 18 sub-elements, and 12 linkage properties were proposed for the linking of bibliographic data, so that a bibliographic environment was established that can interconnect heterogeneous metadata adopted depending on the types of collections. Through the proposed structure, it is expected that it can be applied to provide sufficient information services more efficiently by linking the dispersed bibliographic data of multicultural institutions in an integrated way.

This study is to present improvement plans by examining how Korean literature house websites provide information services. Seventy-nine Korean literature houses out of eighty-eight members of the Korean Literature House Association were studied, except nine that did not construct websites. Three core elements, including website style, literary works information and writer information, together with thirteen sub-elements, were derived from precedent studies. As a result, it was found that 90% of the literature houses were operating websites, but the classification criteria for the literary works and cataloguing rules were not unified, and literature information was not provided sufficiently. Thus, this study suggested improvement plans such as support to build a website, developing cataloging guidelines for literature houses, providing more full-text literature and providing information about literary works and writer.
