Objective : The purpose of this study is to identify and analyze the vocational rehabilitation evaluation tool for the mentally disabled. Methods : For literature search, the Pubmed database was used, and for the analysis, the development year, evaluation method, number of items, scale, and evaluation items were analyzed. In the analysis method, each evaluation item was divided into four categories: function, internal factor, environment, and mental symptom, and the evaluation elements of each evaluation tool were identified. Results : When searching Pubmed through search terms, 161 documents were retrieved. According to the selection method, Griffiths Work Behavior Scale (GWBS), Occupational Functioning Scale (OFS), Social and Occupational Functioning Assessment Scale (SOFAS), Work Ability Index (WAI), Work Behavior Inventory (WBI), Work Environment Impact Scale (WEIS), and Work and Social Adjustment Scale (WSAS) were screened. The evaluation items of all evaluation tools included job-related functional evaluation. According to the purpose of each evaluation tool, internal factors, environment, and mental symptoms were measured. Conclusion : Occupational skills are skills in which various functions such as physical, cognitive, social skills, and coping skills act in a complex way. Therefore, it is necessary to include the four factors analyzed in this study: function, internal factors, environment, and psychiatric symptoms.

More than a decade after its initial proposal, deployment of IP Multicast has been limited due to the problem of traffic control in multicast routing, multicast address allocation in global internet, reliable multicast transport techniques etc. Lately, according to increase of multicast application service such as internet broadcast, real time security information service etc., overlay multicast is developed as a new internet multicast technology. In this paper, we describe an overlay multicast protocol and propose fast join mechanism that considers switching of the tree. To find a potential parent, an existing search algorithm descends the tree from the root by one level at a time, and it causes long joining latency. Also, it is try to select the nearest node as a potential parent. However, it can't select the nearest node by the degree limit of the node. As a result, the generated tree has low efficiency. To reduce long joining latency and improve the efficiency of the tree, we propose searching two levels of the tree at a time. This method forwards joining request message to own children node. So, at ordinary times, there is no overhead to keep the tree. But the joining request came, the increasing number of searching messages will reduce a long joining latency. Also searching more nodes will be helpful to construct more efficient trees. In order to evaluate the performance of our fast join mechanism, we measure the metrics such as the search latency and the number of searched node and the number of switching by the number of members and degree limit. The simulation results show that the performance of our mechanism is superior to that of the existing mechanism.

This study focused on understanding the Korean university students' (both undergraduates and graduates) use of foreign language for scholarly information retrieval especially in different search strategies employed based on users' characteristics. A new model was developed based on Ellis's behavioral model of information seeking strategies. The research applied both quantitative and qualitative methods to analyze the data. The students used a variety of foreign language information seeking strategies at different stages of academic information retrieval based on his/her field of study or level of education. The liberal arts and social science students had more difficulty in selecting proper search terms in the foreign language than the science and technology students. This difficulty resulted in less preference for using foreign language queries by the liberal arts and social science students. The students relied more on the bibliographic and citation information in scholarly information retrieval using foreign language queries than the Korean queries. The research outcomes should provide some guidelines on how the Korean university libraries offer information literacy programs and other services based on the patrons' characteristics.

This study attempted to examine the research trends of single-person households with disabilities using a systematic literature review research method. To this end, 2,161 papers published by September 30, 2023 were searched in a total of four databases: KCI, RISS, KISS, and e-Articl, combining related search terms such as single-person households with disabilities, single-person households and disabled person living alone. In five stages, irrelevant literature to single-person households with disabilities was excluded, and the final 13 documents were selected and analyzed. As a result of the study, first, research topics were classified into research topics for single-person households, analysis of the actual conditions and related factors, issues and support measures related to single-person households, and three case studies related to single-person households. Second, women, age, income, interpersonal skills, health, unemployment, and family support are lower in single-person households with disabilities. Accordingly, based on the research results, suggestions for follow-up studies and practical and policy implications for social welfare were presented.

Web2.0은 정치, 경제, 사회 등의 다양한 분야에서 큰 영향을 주었는데 교육 분야에서도 활발한 응용을 볼 수 있었다. Web2.0을 교육적으로 활용할 수 있는 다양한 사이트 중 Wikipedia는 Web2.0의 집단지성을 대표하는 것으로 유명하다. Wikipedia는 오픈소스백과사전으로서 누구나 편집이 가능하고 배타적인 저작권을 가지고 있지 않기 때문에 사용에 제약을 받지 않는다. 현재 267개의 언어로 서비스되고 있으며, 모든 언어를 합하면 1000만여 항목이 넘으며, 앞으로의 발전이 기대되는 온라인 사전이다. Wikipedia는 정보 검색, 정보생성, 위키문법이용 편집, 토론 등의 기본 기능과 사용자문서 관리, 문서역사, 바벨, 위키미디어 프로젝트 등의 응용 기능이 있으며, 집단지성과 즉시성, 발전가능성, 개방성, 대용량성 등의 교육적 장점을 갖고 있으나, 현재 한국 교육 현장에서는 활발히 이용되고 있지 않은 것이 현실이다. 이에 Wikipedia를 초등학교 교육 현장에 적용하는 다음의 6가지 활동을 제안한다. 첫째, 정보검색, 둘째 정보편집, 셋째 정보생성, 넷째 정보토론, 다섯째 학습 결과물의 정리, 여섯째 프로젝트 학습의 활동들을 적용할 수 있다. 브리태니커사전과 비교할 정도로 정확하다는 긍정적인 시각과 누구나 편집을 할 수 있기 때문에 문서훼손이 생겨 부정확하다는 부정적인 시각이 있다. 또한 한국 Wikipedia가 타국의 Wikipedia에 비해 부진한 이유를 찾는 논의에는 여러 해석이 있다. 이러한 논의에도 불구하고 Wikipedia에는 무궁한 발전 가능성이 있기 때문에 교육에 활용할 만한 가치가 있다고 판단된다.

Objective : The purpose of this study was to analyze group programs for the elderly living in communities and to provide basic data for applying effective occupational therapy programs for the elderly in the community. Methods : From January 2009 to December 2019, articles on group programs for the elderly in the community were searched for in the NDSL, DBPia, Riss, and PubMed databases. Based on the inclusion and exclusion criteria, a total 16 out of the 147 identified studies were selected and analyzed. This review analyzed the characteristics of the participants, contents of the group program, session and duration of the intervention, outcome measures, and effect of the group program. Results : Single group pre-post test studies with evidence level III were most common (8, 50.0%), and five (31.3%) of the studies were conducted on the community-dwelling elderly. Across all the 16 studies, there were 10 types of group programs, and the most frequently used was an exercise group program (25.0%). According to the analysis of the group program period, sessions and time, the intervention period was most commonly 12 weeks (37.5%), with 8 sessions or 12 sessions (25.0%). The intervention time in the group program was most commonly 60 minutes (43.8%). Conclusion : This study can be used as a basis for the development of effective group programs for the elderly and patients with dementia in community-based long-term care services.
