국가직무능력표준, NCS(National Competency Standards)는 대학이나 기업체 모두에서 매우 중요한 이슈로 대두되고 있다. NCS는 그동안 직업훈련기관에서 주로 사용되어 왔으나 최근 들어 2,3년제 전문대학뿐만이 아니라 4년제 대학에서도 점차 관심을 가지고 있는 추세이다. 문제해결능력, 의사소통능력, 대인관계능력 등의 NCS의 직업기초능력과 같은 소프트스킬들은 기술이 비약적으로 발전하는 지식정보사회에서는 구체적인 기술능력보다 더욱더 중요성이 증대되고 있다. 본 연구는 NCS의 직업기초능력과 북미와 유럽 등지에서 캡스톤 디자인으로 많이 활용하고 있는 Formula SAE 활동과의 연관성을 대회 현지관찰조사, 학생들이 작성한 대회 관련 문서들 그리고 미국 링컨에서 열린 Formula SAE대회와 한국 KSAE 대회에 참가한 학생들을 대상으로 하는 설문 조사를 통하여 분석하였다. 결과에서 학생들이 참가한 Formula SAE 대회는 NCS 직업기초능력 항들과 전반적인 관점에서 밀접한 속성을 가진다는 것을 알 수가 있다. Formula SAE 활동이 NCS 직업기초능력 향상에 얼마나 도움이 되는가에 대한 설문조사에서 해외 및 국내 모두 전반적으로 리커트척도 5점 만점에 모두 4.0 이상의 점수를 나타내며 도움이 되는 것으로 나타났다. 참고로 양 대회 참가학생들 간에 수학적능력, 의사소통능력, 문제해결능력 항들은 통계적으로 유의미한 관계를 나머지 항들은 유의차가 없는 것으로 나타났다.

Background : The Clostridium difficile is the most important identifiable cause of nosocomial infectious diarrhea and colitis, which lengthens hospital stay. Recently incidence of C. difficile has been increasing in an university hospital, and an intervention for prevention and control of C. difficile associated diarrhea (CDAD) was in prompt need. Methods : Subjects were the patients in the neurosurgical intensive care unit(NCU) where C. difficile was most frequently isolated. To increase participation of various departments, we used the CQI method, because management of CDAD requires a wholistic approach including control of antibiotics, barrier precaution and environmental cleaning and disinfection. Duration of the CQI activities was 9 months from April to December 1999. Results : The identified problems were misuse and overuse of antibiotics, lack of consciousness of medical personnels and the possibility of transmission from the contaminated environment and tube feeding. Education for proper use of antibiotics and management of C. difficile infection, use of precaution stickers, supplement of handwashing equipments, emphasis on environmental disinfection, and the change of the process of tube feeding were done. The CDAD rate in NCU was significantly decreased after the CQI program (8.6 case per 1,000 patient days from January to April 1999 vs 4.8 from May to December 1999). The distribution of neurosurgical wards including NCU among the total number of isolated C. difficile from the clinical specimens dropped from 49.4% in January to April to 33,7% in May to December. The average hospital stay of the neurosurgical department changed from 19.6 days to 15.2 days. Also, the effect of the CQI activities for C. difficile may have affected the incidence of vancomycin resistant enterococci (VRE). Duration and dosage of certain antibiotics used in the NS department were decreased. The distribution of neurosurgical department in the number of VRE isolated patients declined from 18.4% to 11.1%. Conclusion : Infection control of resistant organisms such as C. difficile is likely to be successful when management of environmental contamination an collaborative efforts of decreasing the patients' risk factors such as antibiotics management and decreasing the length of hospital stay come simultaneously. For this work, related departments need to actively participate in the entire process under a common target through discussions for identifying problems and bringing up solutions. In this respect, making use of a CQI team is an efficient method of infection control for gathering participation and cooperation of related departments.

본 논문에서는 증강현실 기반의 협업적 교육 시스템을 설계하고 구현한다. 기존의 증강현실 교육 시스템이 협업성보다는 시스템과 학습자 간의 상호성만을 고려하였기 때문에 학습자들 간의 협력을 지원하고 장려하는 교육 시스템에 대한 효과적인 접근이 이루어지지 않았다. 협업적 교육은 학습자들이 해답을 찾기 위해 비판적인 사고와 협동의 작업을 통해 공동의 목적을 달성하는 교육 방식으로 학습자 간의 긍정적인 상호의존성, 적극적인 상호작용, 개인 및 그룹의 책임감, 팀워크 발달 등이 필요하다. 협업적 교육이 효과적으로 이루어지기 위해서는 교수자와 시스템의 역할이 중요하다. 교수자는 학습활동 초기에 프로젝트를 정의하고, 학습자 그룹을 형성하며, 그룹의 프로젝트에 대한 활동 평가 기준을 제공하여야 한다. 시스템은 상호작용 측면을 지원하고, 학습 활동을 촉진시켜야 한다. 또한 교수자는 학습자들의 상호작용 활동을 관리하고 평가할 수 있는 시스템을 제공하여야 한다. 본 논문은 이와 같이 협업적 교육 시스템에 대한 고려가 적용된 증강 현실 기반의 협업적 교육 시스템을 제안하고 구현한다.

The purposes of this study were to analyze the within-group verbal interactions in Thinking Science activities and compare the characteristics of verbal interactions shown by the pupils as well as the differences in help by e teacher in Korea with those in the UK. For the purposes of this study, 16 pupils from comparable groups by cognitive level were selected from both countries. Verbal interactions and teacher help during group discussions were audio/ video taped and the types of students' interactions were classified into interactions related to problem solving, management of classroom loaming and others. The results of this study showed that the verbal interactions in Korean groups were more activated than those in the UK groups. However, the percentages of high level interactions such as metacognitive questions, elaborative suggestions and logical argumentations were higher in the UK groups than those in the Korean groups. Observation of the within-group activities revealed that the pupils of both countries shared some common ground in the following ways; neither recognized the need to formulate the hypothesis in the process of inquiry and that the procedures of discussion were dominated by the pupils of higher cognitive level as the discussion proceeded. It was also observed that the pupils in the UK were considerate in response to the questions posed by both their peers or the teacher, while the pupils in Korea were influenced by their prior knowledge in the subject. Analysis of the teacher help during the inquiry activities showed that the tendency fur the teacher to emphasize the process rather than the product in the procedures of discussion and the extent he/she allowed the pupils to think and consider were closely related to the characteristics of the teacher himself/herself and was found to be a point of commonality in both countries. However, the teachers in the UK revealed the tendency of trying to propose the task to the pupils in concrete and systematic ways and guide the discussion based on the thinking of the pupils, while those in Korea tried to use strategies designed to draw out active verbal interactions among the pupils.

Many students who attend university are worried about their future employment and academic achievement. Self-leadership is the ability to deal wisely with employment matters and to recognize the employment strategies of students who display self-leadership qualities. For this purpose, 320 questionnaires were distributed to students attending universities in Seoul. The 304 collected questionnaires were used as data for the final analysis. First, the university students' average self-leadership rate was 3.73, and their average employment rate was 3.24. In terms of self-leadership by subordinate domains, the most common strategy was to introduce "natural compensation activities", and the least common strategy was to focus on "inner compensation". For the employment strategy, "academic credit" was the best managed, and "active behavior" was the least well managed. Second, in terms of the differences in self-leadership due to social demographic variables, the self-leadership levels showed significant differences, according to their credits in general. Furthermore, they showed significant differences depending on gender and the leadership experience among the subordinate variables. Moreover, the university students' employment strategies showed significant differences according to gender, leadership experience and leadership education. Third, in terms of the difference between self-leadership and employment strategies due to psychological variables, self-efficacy and university-life satisfaction levels made significant differences in terms of self-leadership. Fourth, the group with high self-leadership levels also had highly developed employment strategies, compared to the group with low self-leadership levels. Fifth, after analyzing the social demographic variables, the psychological variables and the influence of self-leadership, it appears that the explanation level increased at each step. This study demonstrates that experiencing many opportunities that promote self-leadership during university causes students to worry about their future careers and prohibits them from developing into independent, responsible adults who can accomplish their goals.

This study analyses characteristics of space to facilitate community centering on cases of collective houses in Japan and uses the results as basic data to activate collective houses as an alternative form of housing in our country. To identify the characteristics of space for active communities with collective living space, this study conducted a theoretical examination on collective houses and housing, derived territoriality, accessibility, comfort and safety as factors of community activation and analysed various cases, and the results are presented as follows: First, territoriality is a necessary condition for formation of community, and a confined and physical space. It indicates the proper size of a space and diverse spacial areas which meet the needs of residents with the proper size and amount of space (space which can accommodate diverse generations including women, the aged and the young, flexible space which changes according to the purposes and program, space which supports leisure and hobby activities, and space which can accommodate outsiders). Second, accessibility indicates an environment which supports residents' easy use of space. As the more accessible it is, the higher the frequency of its use, spatial factors (piloti, backyards, benches and tables) should be provided, community space should be arranged in a central or decentralized way and community living space should be made for each floor. As for exits, accessibility should be considered in every way; entrances connected with community spaces, open entrances and entrances accessible from outside or individual living spaces. Third, comfort satisfies the physical and mental needs of residents through separation of floors and flows between the community and individual spaces for privacy and formation of eco-friendly spaces including vegetable gardens, gardens and plant arrangements. Fourth, safety should be considered for a higher quality environment with psychological stability and comfort, for which the following are recommended: installation of hand-rails, removal of thresholds, spacial design for the socially weak, duplex and open type structures for community space, open stages and halls, as well as indoor and outdoor openness through the use of windows.

There is an increasing curiosity in Nordic as well as Far East Asian countries about senior cohousing, where the middle-aged and elderly people, 55+. form a community for independent living. What are the ideas behind senior cohousins? Why are people moving to senior cohousing community? What may senior cohousing provide and mean for individuals and groups of the elderly? Is senior cohousing a sustainable idea for future generations of elderly people? There is a curiosity among elderly people looking for interesting alternatives. Municipalities and state authorities hope that senior cohousing can contribute to the welfare of the elderly as the scope far support by the public sector is decreasing. Actors in the building sector are interested In investment and meeting the demands. In Denmark and Sweden the senior cohousing concept had a revival around 1985. In Denmark there has been a vivid discussion and plenty of books have been published. In Sweden there are few evaluations but an increasing interest. From different points of view, Danish, Swedish and Nordic as well as Far East Asian countries, there is a concern to explore and compare to get more facts and deeper understanding far further actions. This is a comparative study of inhabitants' life satisfaction in cohousing communities in Denmark and Sweden. The study is based on discussions with cohousing providers, study-visits in cohousing communities and a questionnaire to residents themselves. Study-visits took place during springtime and the questionnaires were handled spring and summer of 2002. 655 seniors responded to the questionnaire from 14 seniorbofae llesskaber (rented or housing cooperatives) in Denmark, 11 seniorhus within the SABO sector (municipality owned housing with rental apartments) and 8 housing cooperatives initiated by the Seniorgarden Housing Company in Sweden. Data were analyzed by SPSS program, using frequency, percentage, cross-tab and chi-square test. This paper focused three major areas of interest; 1)characteristics of the inhabitants. 2) participation in common activities and mutual cooperation among residents and 3) evaluative outcomes from the inhabitants' points of view. Mainly the inhabitants expressed quite positive experiences of their living environment and everyday lift and a few difference was found in life satisfaction between Denmark and Sweden.
