A large amount of efforts are required to search user's preferred contents for the program contents being provided by IPTV services. In this paper, using collaborative filtering, an automatic recommendation method of IPTV program contents is presented by reasoning similar group preferences on IPTV program contents which constitutes personalized IPTV environments. The proposed method models the user's preference of IPTV program contents with the program attributes such as content, genres, channels actor/actress, staffs and calculates it using the watching history of program contents in different genres and watching times. Also, the proposed method considers timely changing user's preference and the preference oon the content itself, which improves the traditional collaborative filtering methods that can not recommend the non-consumed items.

Purpose: The purpose of the study was to find the strategies of mental health screening in school. Based on the literature review, we discuss the importance of screening students in schools for mental health problems. Methods: Data from the 2008 Korean Mental Health Screening in Schools(2008-KMHSS) are used to estimate the outline of this screening. We administered the questionnaire for satisfaction of 2008-KMHSS for students(N=1,280), parents(N=2,672), school nurses(N=75), teachers(N=685), district personnels(N=6), and mental health center staffs(N=37). Also we interviewed a part of them by telephone and e-mail. And we reviewed the tools and methods for screening students for emotional/behavioral problems. Results: Mental health screening in schools is a very important, yet worrisome, agenda that is in its very early stages. From the 2008 Korean Mental Health Screening in Schools, 9,588 students(12.9%) needed more evaluation in the first stage. Of these, 6,910(72.1%) completed the second stage screening. In this sample, 1,975(28.6%) utilized the mental health services in school or community. 38.3% of students and 43.7% of their parents notified the 2008-KMHSS. But only 12.1% of students and 10.9% of their parents dissatisfied with the screening. 9.9% of teachers and 22.7% of school nurses dissatisfied with the screening. Among them the school nurses were mostly dissatisfied, and they complained work burden from KMHSS. Mental health center staffs complained similar issues. The Children's Problem-behavior Screening Questionnaire(CPSQ) and Adolescents' Mental-health & Problem-behavior Screening Questionnaire(AMPQ) were compatible to screen students in schools for mental health problems in first stage. Conclusion: Mental health screening in schools needs careful planning and implementation. For successful mental health screening in schools, several elements need to be considered: careful planning, collaboration, staff training, and integrative mental health programs and services in community or schools.

This paper proposes a Product Data Management (PDM) system architecture that supports end-user computing for small and medium businesses (SMBs) in Korea to build and maintain efficient and sustainable information systems for their product development. Its open database with relational tables enables existing common application programs such as Microsoft office suites to access product data in PDM systems. In addition, the interactive query processor provided by database management systems helps design engineers to build ad hoc queries in standard SQL database language to response different data requirements during their product development. The PDM architecture with the open database allows design engineers or technical staffs in SMBs to build and maintain their application programs for product development by themselves. To show the feasibility of the proposed architecture, this study implemented a prototype PDM system based on the architecture and database, and represents real-world product data with the implemented PDM system.

This study was undertaken to investigate the effectiveness of a hospital organization targeting both hospital administrative staff members and internal/external customers under a rapidly changing organizational environment, where the effect of creative behavior on passion about one's job was controlled with the participation of 55 people from two larger general hospitals, with 103 people from four general hospitals, with 51 people from eight regular hospitals. Thus, data from a total 209 people were collected. The creative behavior of hospital administrative staff members working for general hospitals and larger general hospitals significantly affected job engagement, showing that 'Relevant knowledge, maintaining status, and application appetite' were higher than the scores of 'new knowledge pursuit activities.' However, a weaker relationship between creative behavior and job engagement was found in medical institutions than for hospitals.

As growth of the web-based applications, the requirements of the users who have been very familiar to the web-based user interfaces and customer-oriented services on the Internet would become more knowledge-intensive and higher technology involved in a more convenient and polite way of service delivery. Therefore, the service quality of information system department should be considered as a very important factor influencing success of information systems. The objective of this study is to provide the relationship between service quality of IS department and its impacts such as use, user satisfaction and job performance. For this purpose, we provide a research model for it and test it empirically for the users of the corporate portal in one of main telecommunication service providers in Korea. In result, our model with satisfiable validity and reliability shows not only importance of IS departments' service quality but also two-faced characteristics of service quality. That is, while technical competence which means with knowledge and expertise of IS department staffs is more related with user satisfaction on information systems, personal service which means the way and manner of service delivery is more related with use of it.

Recently, there are much improvement in optical and mechanical properties of dental ceramic materials coupled with improved fabrication techniques, which have caused a considerable shift in the preference of the dentists to ceramic restorations. Because the chemical composition and microstructure of all-ceramic materials are different by the type, correct choice of cement type and surface treatment procedure, and cementation strategy is essential for the success of ceramic restorations with adequate retention and decreased incidence of complications. This manuscript reviews on the most often prescribed and some newly developed ceramic materials, and the selection criteria and usage guidelines of cement materials that are used in conjunction with various ceramic materials. This manuscript emphasizes that continuous updating the information of newly developed ceramic and cement materials and application techniques by the dentists and dental staffs are demanding in response to the constantly improving ceramic and cement materials and corresponding application protocol changes.

Since domestic and international environments has changed rapidly, Korean primary agricultural coopratives are expected to face many difficulties in business management, especially marketing and banking business. Therefore, it is necessary to reframe the exitsting structure of primary agricultural cooperatives so as to enhance the competitiveness in terms of management efficiency. However, There are many problems to be solved such as overnumbered staffs compared with decreasing number of farming population, unbalanced ratio between executive officials and lower-level officials, complexity of position-ranking system resulting from unclearness of official title and office regulations, and management right excessively concentrated on cooperative leader. The suggested measures for such problems are as follows; 1) attaining the economy size of agricultural cooperaitves in line with decreasing rural community, 2) fostering the on-the job training programs and the personnel administration according to job competency, 3) merging the small primary cooperatives into larger units with efficiency, 4) specializing the cooperative business based on their regional comparative advantage, 5) maintaining the rational adjustment between elected cooperative leader's management right and responsibility.
