  • The purpose of the study was to investigate the effects of On-Line Community Assisted Team Learning (OCATL) activities on academic achievement and team member's Shared Mental Model(SMM) subscale scores. Two studies were conducted over two semesters in different universities. The first study was aimed at examining the effects of OCATL on university students' academic achievement using pre- and post- experimental design. For this experiment, 133 university students composed of 80 male and 53 female students from 13 colleges participated. The OCATL activities included the orientation of OCATL, seminar on collaborative learning, on-line community assisted team learning with sixteen hour participation during one semester and a final report (or a term paper). To measure these students' academic achievement, their pre- and post-semester's GPA were compared. The results of paired t-test revealed a significant difference in academic achievement (p<.05). The second study was designed to compare the scores of SMM subscales of the experimental group with the OCATL activities and those of the control group without using OCATL activities. The data was collected using the scale of Shared Mental Model(SMM)-short version developed by Johnson in 2011[18]. For this study, 74 participants from 10 teams served as an experimental group and 15 teams which were not exposed to OCATL activities served as a control group. The MANOVA results showed that SMM subscores of two groups measured after the experiment were statistically significantly different: The experimental group with the OCATL activities showed high scores on general task and team knowledge, general task and communication skills, attitudes toward team and task, team dynamics and interactions, team resources and working environment, and satisfaction with the team.

  • 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.
