이 연구는 온라인 학습커뮤니티 보조의 팀 학습(Online-Community Assisted Team Learning: OCATL)이 대학생의 '학업성취도'와 '공유된 정신모형(Shared Mental Model: SMM)'에 미치는 효과를 검증해내는데 있다. 각기 다른 지역에 소재하는 대학교의 대학생을 대상으로 2학기 동안 두 개의 연구가 실시되었다. 우선, 연구1에서는 OCATL을 실시하고 대학생의 학업성취도에 변화에 미치는 영향을 알아보기 위해 133명(남학생 80명, 여학생 53명)의 참가 대학생들의 OCATL 참여 전 후 학점에서의 평점평균(GPA)를 사용하여 비교하였다. OCATL 활동에는 '오리엔테이션', '협동학습 세미나', '온라인 학습커뮤니티 보조의 학기별 16시간 이상의 팀 학습', '최종보고서 제출'의 과정이 포함되었다. OCATL 활동 전후의 학점에서의 점수변화를 t검증을 통해 비교한 결과 통계적으로 유의한 차이가 나타났다(p<.05). 또한, 연구2에서는 OCATL을 실험집단(10팀)에 제공하고 통제집단(15팀)에는 온라인 학습 커뮤니티 보조를 제외한 팀학습을 하도록 하여 활동이 종료된 후에 SMM에서의 척도 점수를 비교하였다. 실험집단과 통제집단의 총 학생수는 74명이었다. SMM 측정은 Johnson(2011)이 개발한 SMM 척도의 단축문항지를 사용하였다. 분석결과, 팀 학습 이후 측정한 SMM 점수에서는 통계적으로 유의한 차이가 나타났다. 다변인분산분석(MANOVA) 결과, 온라인 학습 커뮤니티 환경을 지원된 팀학습 실험집단과 통제집단 간에 유의한 차이가 있었다. 또한 SMM의 하위 구성변인을 종속변인으로 하고 집단을 독립변인으로 한 단변랑 분산분석(ANOVA) 결과, '일반과제와 팀지식', '일반과제와 의사소통기술', '팀원과 과제에 대한 태도', '팀역동과 상호작용', '팀 자원과 활동환경', '팀만족도' 점수에서 실험처치 후 통계적으로 유의한 차이를 보였다($p$ <.05).

In line with the previous study on the level of social cohesiveness of public rental housing communities in Seoul, this study investigated the community activities as a result of community cohesiveness and identified the cultural influences on the cohesiveness of the same case study areas. In general, there was relatively more active and voluntary participation of the residents in the community activities in the housing estates with higher social cohesiveness. The four communities were active in reporting community problems to the housing managers, greatly relying on the housing managers to solve the problems. In addition, mutual aid and community self-help were facilitated mainly through the activities of women's associations. However, small membership of community organisations and occasional disputes between the community organisations and estate managers, and among the community organisations themselves, seemed to have hampered the positive effects of the social cohesiveness in the case study areas. In terms of the cultural attributes, coexistence of collectivism and individualism, consideration of neighbourliness as an ideal social norm, incorporation of the neighbourhood environment into the housing estate environment and extensive use of outdoor public spaces were found.

On community data. sampled in regular intervals on a long-term basis. artificial neural networks were implemented to extract information on characterizing patterns of community changes. The Adaptive Resonance Theory and Kohonen Network were both utilized in learning benthic macroinvertebrate communities in the Soktae Stream of the Suyong River collected monthly for three years. Initially, by regarding each monthly collection as a separate sample unit, communities were grouped into similar patterns after training with the networks. Subsequently, changes in communities in a sequence of samplings (e.g., two-month, four-month, etc.) were given as input to the networks. After training, it was possible to recognize new data set in line with the sampling procedure. Through the comparative study on benthic macroinvertebrates with these learning processes, patterns of community changes in chironomids diverged while those of the total benthic macro-invertebrates tended to be more stable.

This study examines the current status on the supply of community facilities based on the supply criteria of present welfare facilities. Analyzing satisfaction of residents about community facilities based on physical supply criteria. The study sets up the concept and proposed trend of the related studies and distinction through the examination of previous researches. Next, the present systematical supply criteria, was used to make indication in order to propose the promotion of improvement on supply criteria for community facilities. Multi dimensional analyzing system and the satisfaction level of the community facility was used to analyze the relationship between the two. The direction of policy improvement according to the analysis is as per the following. First, it is necessary to improve supply criteria of household to guarantee the minimal amount of space. Second, specification of the minimum distance of community facility to residential area in the complex is needed. Also, the presentation of bottom boundary line of the formation area size to expand the size up to minimal level of size is needed. Third, resident exercise facility supply criteria among the community facility supply criteria need to be improved from the number of household base to the size for each household base. Forth, resident resting facility criteria among the community facility supply criteria should be changed from the present criteria of one facility per five hundred households.

The objective of this study is to identify the impacts of communication reinforcement on performance of learning in Web-PBL. Communication reinforcement is defined as the combination of information sharing and co-construction. As factors facilitating communication reinforcement, we propose learner's characteristics, task characteristics, and group characteristics. Learner's characteristics are collaboration-orientation, openness, holistic approach, and online community-orientation which reflects e-learning environment. Collaboration-oriented tasks as group projects were developed and given to groups with 5-6 members. The group characteristics are categorized into 'horizontal' and 'vertical', according to the patterns of communication between a group leader and members. To verify empirically the proposed research model, an experimental design was performed to learners who took on-line and off-line courses with group projects. We found important results as follows; First, field dependence has positive impacts on information sharing, and online community-orientation has positive impacts on co-construction. These results correspond with prior studies on relationship between field dependence and collaborative learning. Second, collaboration-oriented task directly impacts on information sharing, and indirectly affects co-construction, This result implicates that information sharing is pre-requisite of co-construction. Third, 'horizontal' was identified as a factor giving positive effects on information sharing and co-construction. This result implies that horizontal communication is very important to facilitate communication reinforcement.

This study aim was to understand the effects of the change of the sleeve cap height on the sleeve cap line and the sleeve appearance by making nine different sleeve cap height patterns. When a subject sews the virtual and real garments with this, it provides data base through which she can make the suitable sleeve by conducting a comparative analysis of the appearance and cross-sectional diagram and grasping the relation between the sleeve cap line ease and the shape of the sleeve. As a result of the analysis of the image of 3D virtual garment, the shape of the armscye and the position of the bust line and sleeve baseline, the sleeve cap height and the sewing ease of the sleeve cap line affect on the shape of the sleeve and the armscye. Although the real garment is slightly different from the virtual garment they have shown similar tendency. Therefore, if the 3D virtual clothing system is used appropriately, it is possible to expect various study results in the apparel field without making real garments.

This study analyzed some of nursing homes in various domestic and foreign regions in order to find solutions to reduce suicidal incidents from the loneliness. To analyze community space of nursing homes, elderly community is analyzed into three categories based on their characteristics (morphological characteristics, Social characteristics, Environmental characteristics). With those three characteristics above, architectural spaces are analyzed the relation with them. Elderly nursing homes are divided with living, nursing, management, and public spaces. The space of elderly nursing homes (classification of function)-elderly community (classification of elderly characteristics) is approached in an architectural way related to the space of elderly nursing homes and elderly characteristics. Through some case studies, specific space relation of elderly nursing homes and elderly community is analyzed. Also, with the building analysis for summary, plans, wards(hospital rooms), cafeteria, program rooms and alley, some of general information and elderly community space is understood. In this study, there will be an analysis of relation of elderly community(morphological, social, environmental characteristics) which is separated into some spaces of elderly nursing homes(living, nursing, public spaces and facilities) written above. Furthermore, if people can recognize the importance of community space for elderly facilities, there will be a new guide line for that which can have a play on catalyst.
