This study aimed to investigate differences in the purchasing patterns of and the levels of satisfaction with cosmetic products, and the method of disposing dissatisfied cosmetics for female university students among China, Japan and Korea. Survey was conducted with 1,200 female coeducational university students in Beijing, Tokyo and Seoul and 1,115 were used for the data analysis. Data were analysed by frequency analysis, Cronbach's ${\alpha}$, chi-square analysis, analysis of variance, Duncan's Multiple Range test. The results showed significant differences in purchasing behaviors in China, Japan and Korea. Japanese students mainly got information through objective sources, while Koreans did so through human network. Regrading the evaluative criteria for basic care items, function and effect were the most important criteria for Chinese and Korean consumers and skin compatibility for Japanese. For color make-up, Chinese, Japanese and Korean respondents respectively cared the most on brand image, convenience of purchase and the current trend. Chinese tended to shop cosmetics at department stores due to store reputation, Japanese preferred supermarkets and pharmacies and Koreans shopped at discount stores for low price. The most influential human sources were friends and colleagues for Chinese and Korean, and models on advertisements and magazines for Japanese. Korean respondents displayed the highest level of satisfaction with cosmetics followed by Japanese and Chinese. As for the methods of disposing dissatisfactory cosmetics, Chinese were the most active in exchanging for other product; Japanese and Korean were not likely to use or throw the products away.

In this paper, firstly we describe the structure and the performance of our ICPS(Information Communicaion Processing System) which currently provides information retrieval services, and then make a proposal for the construction of the open-networking information communication infra-structure which enables us to fully pre-pare for the emerging information society. In detail, the structure and the methodology needed for the implementation of the billing function on behalf of all information providers by using the user access network number as a user identification number while guaranteeing the equivalent access to the multiple value-added networks, are suggested. Based on the above ideas, the AICPS(Advanced Information Communication Processing System) has been designed and implemented. Final system performance evaluation with the assumption of a poling system as a system model, shows that our system can handle 10,000 user simultaneously who are using V.34 28.8 kbps modems and the processing capacity is 288,000 packet/sec. This result is so far superior to our target performance established during the desingning procedure. Namely, our system was originally designed to accommodate only 960 users at the same time. By taking advantage of this excessive high performance of our system, many other users can easily access the new services which are accessible only throught the ISDN or the Internet.

Using webometric big data, this study examines the diversity of online information sources about the novel coronavirus causing the COVID-19 pandemic. Specifically, it focuses on some 28 countries where confirmed coronavirus cases occurred in February 2020. In the results, the online visibility of Australia, Canada, and Italy was the highest, based on their producing the most relevant information. There was a statistically significant correlation between the hit counts per country and the frequency of visiting the domains that act as information channels. Interestingly, Japan, China, and Singapore, which had a large number of confirmed cases at that time, were providing web data related to the novel coronavirus. Online sources were classified using an N-tuple helix model. The results showed that government agencies were the largest supplier of coronavirus information in cyberspace. Furthermore, the two-mode network technique revealed that media companies, university hospitals, and public healthcare centers had taken a positive attitude towards online circulation of coronavirus research and epidemic prevention information. However, semantic network analysis showed that health, school, home, and public had high centrality values. This means that people were concerned not only about personal prevention rules caused by the coronavirus outbreak, but also about response plans caused by life inconveniences and operational obstacles.

In these days, we have increasing demands on the real-time services, especially for the multimedia data transmission in both of wired and wireless environments and thus efficient and stable ways of transmitting realtime data are needs. Although RTP is widely used for internet-based realtime applications, it cannot avoid packet losses, due to the use of UDP stack and its underlying layers. In the case of mobile computing applications, the packet losses are more frequent and consecutive because of the limited bandwidth. In this paper, we first statistically analyze the characteristics of packet losses in the wired and wireless communications, based on Gilbert model, and a new packet recovery scheme for realtime data transmission is presented. To reflect the transmission characteristics of the present network environment, our scheme makes the sender to dynamically adjust the amount of redundant information, using the current packet loss characteristic parameters reported by the receiver. Additionally, we use relatively large and discontinuous offset values, which enables us to recover from both of the random and consecutive packet losses. Due to these characteristics, our scheme is suitable for the mobile computing environment where packet loss rates are relatively high and varies rapidly in a wide range. Since our scheme is based on the analytic model form statistics, it can also be used for other network environments. We have implemented the scheme with Mobile IP and RTP/RTCP protocols to experimentally verify its efficiency.

This study was carried out in order to develop and validate the Korean Version of Strengths Scale for individuals with mental illness. The first step taken to develop the scale was to construct sample items for the Strengths Scale using literature research and three focus group interviews of individuals with mental illness. Secondly, two professors of the Social welfare Department of a University and two mental social workers reviewed these sample items to select and compile a final version of the scale. Lastly, the scale's reliability and validity was verified through an empirical study of 478 individuals with mental illness who conduct the survey items. The explanatory factor was that the sample items can be grouped into seven factors. Factor 1 was 'Vocation', Factor 2 was 'Family and Social Support', Factor 3 was 'Optimism', Factor 4 was 'Resources Utilization', Factor 5 was 'Coping Behavior', Factor 6 was 'Leisure', Factor 7 was 'Health'. The Confirmatory analysis showed that the model demonstrated a goodness- of-fit. Finally, the Korean Version of Strengths Scale for individuals with mental illness was developed consisting 40 items and was proposed a mental health social work implications.

This study was an exploratory study for the development of a competency-based social welfare curriculum. This study was conducted through a literature review focused on guidelines for social welfare published by the KCSWE (Korean Council for Social Welfare Education). The purpose of this study was to explore social welfare professional competencies, subject goals, teaching methods, and the participatory learning environment for the development of a competency-based social welfare curriculum. The findings are as follows. First, each university had been researching professional competencies individually. Second, the social welfare subjects tended to include all elements of knowledge, skills, and attitudes, and these goals were matched with professional competencies set by each university. Third, the guidelines for social welfare subjects provided various teaching methods to achieve the goals of the subject as well as a participatory learning environment based on discussion. However, it was difficult to determine whether the various teaching methods were effective in achieving core and professional competencies. Therefore, it is necessary for KCSWE to set up a standardized competency-based curriculum and research professional competencies based on social welfare, a curriculum and subjects according to their competencies, effective teaching methods, and a method for evaluating educational outcomes.

Recent changes in landscape architectural field, such as keen attention on central and local government, checks of other related fields, circumstances both inside and outside the construction industry, assume hostile attitude towards qualification system in landscape architecture. By securing the original function of qualification meets the environmental changes and accords to the technical development, practicality and serviceability of qualification as well as credit rating and professional status can be enforced. Framework redesign on landscape architecture National Technical Qualifications(NTQ) is required in order to meet the demand in the industrial fields and to reflect the technical changes. National Competency Standards(NCS) was selected as a precedent study to enhance the practicality and serviceability of NTQ as well as to avoid duplication on qualified requirements. It would provide a model to redesign the framework of landscape architecture NTQ. In this study, questions in NCS and in landscape architecture certification are compared and analyzed to review the suitability of the present landscape architecture certification items. In conclusion, the creation of master landscape architect under the present system, and the subdivision of the technician's license level to planting technician and the facility are recommended. The ability units to be qualified for each level, which would be used for future NTQ standards and university curriculums in relevant fields, are also suggested in this study.

Bicycles are leading to serious accidents in the event of a side collision, and it is very important to prevent accidents in advance because it is difficult to actively deal with them in a dangerous situation. As a part of the bicycle safety driving support technology, this study establishes bicycle accidents dangerous zone based on bicycle accident data and road property information of digital map nationwide and provides timely safety information to cyclists. The point selected by using actual accident data was called 'dangerous zone', and the potential accident occurrence point generated by modeling based on this 'dangerous zone' was called 'logical dangerous zone'. As a result of the research on the Designation of Logical Bicycle Accident Dangerous Zone, the regional specificity of the bicycle accident points across the nation was generalized to the form of the logical dangerous zone through the network data.

이 연구는 1990년대 이후 헝가리 농촌지도의 특징적인 변화를 고찰하였다. 헝가리의 농촌지도사업은 오랜 역사를 가지고 있으며 주로 대규모 농장을 대상으로 한 농업기술전파에 주력하였다. 1990년대 이후 사유재산의 인정과 시장경제체제로의 전환과 함께 시장에서의 경쟁력이나 지속성에 대한 요구는 농촌지도사업의 방향전환을 요구하게 되었다. 유럽연합의 농업정보시스템 표준화에 요구와 헝가리 내의 농산업구조의 변화는 농업정보시스템 구축의 필요성을 낳게 되었다. 헝가리에서 농업정보시스템의 개발은 농업경제연구정보원(AKII, Research and Information Institute for Agricultural Economics)과 중앙통계사무소(Hungarian Central Statistical Office)에서 이루어졌다. 시스템 개발의 주요 분야는 농업통계, 농장회계자료네트웍, 시장정보시스템의 세 가지이며 이들의 복합적인 농업정보시스템으로 형성되었다. 본 연구에서는 위의 세 가지 주요 범주의 개발배경과 진행사항, 문제점들을 살펴보고 개선방향을 제시하였다. 헝가리 농업 농촌개발부(The Ministry of Agriculture and Rural Development)의 최근 정책의 특징은 전국적인 농촌지도상담 네트웍의 구축이라고 할 수 있다. 현재의 헝가리 농촌지도사업체계는 크게 세 부분으로 나누어 볼 수 있다. 첫째 농업농촌개발부의 군사무소는 지역사회의 독농가나 선도농가와의 밀접한 관계를 유지하며, 이러한 독농가나 선도농가로 하여금 지역의 농민들에게 도움을 줄 수 있도록 하는 것이다. 둘째는 민간 자문가들이 농장을 방문하여 현장에서 농민들에게 전문적인 도움을 주도록 하는 것이다. 민간 자문가들은 도 단위의 전문지도사들로부터 정보나 기술에 대한 전문적인 도움을 받는다. 세 번째는 전문교육기관을 통한 농민들에 대한 직접적인 교육이다. 이러한 교육들은 농민들에게 무료로 제공되며, 교육과정이나 프리젠테이션, 전시 등을 통해 이루어진다. 현재 헝가리 농촌지도체계는 그 실행과정, 효율성, 조직적인 면에서 완성되지 못하였고 전환기에 처해 있다. 효율적인 농촌개발을 위해서는 농촌지도상담의 효과나 조직면에서 많은 연구와 정비가 필요한데 이는 헝가리의 국가적 이익의 증대와 유럽연합의 목적에 부합하기 위해서도 적극적인 관심과 노력을 필요로 하는 분야이다. 이러한 필요성을 바탕으로 농촌지도사업의 새로운 모델을 제시하면, (1) 수도인 부다페스트에 농촌지도사업을 전반적으로 책임지는 중앙부서를 설립하여 효과적인 농촌발전을 지원하여, (2) 7개의 도에 농학계 대학과 연구소를 중심으로 하는 지역센터를 설립하여 도내의 농촌지도상담활동과 영농에서 농업관련 사안에 대해 문제해결 중심의 도움을 주도록 하며, 지역센터는 자율적, 독립적으로 운영하도록 하고, (3) 50여개의 군에 일선지도기관을 설립하여 농업인들이 쉽게 방문할 수 있도록 하며, 지역의 특수한 상황이나 사안에 대해 융통성 있게 대처할 수 있도록 하는 것이다.
