새로운 커뮤니케이션 플랫폼인 소셜네트워크 서비스(이하 SNS : Social Network Service)는 다양한 정보의 빠른 전달과 함께 상호신뢰를 바탕으로 의사소통을 강화하고 친밀감을 형성해 조직 활성화에 기여하였다. SNS의 사회적 중요성이 높아짐에 따라 군에서도 SNS를 통해 자발적 참여와 신뢰관계 구축을 바탕으로 군내 외 유대감 강화에 활용하고 있다. 그러나 국방 SNS 도입시 개인정보의 노출이나 프라이버시 침해, 군사자료의 유출 등과 같은 역기능은 군에 치명적인 요인이 될 수 있어 이에 대한 보안대책이 필요하다. 본 논문에서는 국방 SNS 도입을 위해 SNS 기능별 유형을 분류하고, 유형별 구조를 분석하여 국방 SNS에 필요한 보안기능요구사항을 제시하고자 한다.

Smart wear integrates computing technology into fabric or a garment for additional functionality. This research explored the attitudes and opinions of the use of smart wear from the viewpoint of caregivers. Thirty two individuals including care providers of children and adult family members with health problems participated in focus group interviews. Participants reported being interested in smart wear because of the potential to detect the location (GPS) of a dependent (e.g., child, elderly) and to monitor vital signs. Participants indicated perceived advantages of smart wear such as identifying geographical location and effectiveness. Perceived concerns mentioned were privacy/security issues and accuracy of data. Participants taking care of dependents without a specific disease were hesitant to adopt and pay for smart wear. However, caregivers of elderly individuals expressed positive adoption intentions and willingness to reasonably pay for smart wear. They indicated expectations that potential insurance would provide coverage for cost savings. Caregivers expressed the need of specific requirements for future adoption such as customizability, and comfort/safety. Specific to smart wear clothing, most respondents preferred it be an undershirt or a jacket with a sensor located in the shoulder area. The findings from this study can be used in product development, promotion and marketing of smart wear.

Activities in the dwelling are inseparable from housing design. Spatial features often result from patterns of activities that take place within the dwelling. Activities are further elaborated to affect house plans, furniture, arrangement, and equipment. However, discrepancies still exist between housing design and behavior, where housing design often fails to accommodate activities and behavioral dimensions within the family and the dwelling. This paper addresses the relationship between dwelling activities and housing design by means of a qualitative study that aims to understand the needs of the Indonesian dwelling through activity analysis. To do so, the research adopts a methodology that involves collecting data from measurements of the house, house plan analysis, and photographs, in addition to in-depth semi-structured interviews with families. Taking Bandung as a case study, 9 houses and families were selected as respondents that share similar family life-cycles, number of family members, and building size. The findings from the study suggest that spacious and open plans are preferred by the family, while maintaining family privacy. Guest areas are used to host formal guests and to restrict visitor access in the house. Service areas such as kitchens and laundry areas are the core areas for household activities for cooking, laundry, and drying. To meet social activities such as community gathering, open plan design is necessary to allow flexibility of furniture reconfiguration to accommodate extra guests.

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.

This study had the purpose of presenting a residential environment solution as a desirable educational environment for middle school students to grow soundly and to achieve proper self-realization while providing basic materials to build up a suitable residential environment by comparing and analyzing what relationships exist between different home backgrounds, residential environments and middle school students' social maturity. This research was conducted from Feb. 11, 2008 to Feb. 13, 2008. The subject of this research was 601 students in 3 middle schools located in Gyunggi-do. The data analyzed used the SPSS 11.5 version. The summary of this study's results is as follows. First, in terms of home background, the higher the parents' educational background and social and economic position, the greater the students' social maturity. Second, in terms of home environment, the more spacious the living space, the better the water and sewage system and rest room, the more convenient the air conditioner and kitchen system, the better the lighting, ventilation, soundproofness, insulation, the less the danger in relation to fire, crime, traffic accidents, disaster, the greater the students' social maturity. Third, in terms of the home environment related to the correlation between the residential environment and social maturity, all areas such as housing facilities, housing structural environment and housing safety showed static correlations and proved that the residential environment has an important influence on social maturity. Accordingly, in order to build up an ideal residential environment, we should make efforts to expand and improve better facilities at home considering privacy, lighting, ventilation, soundproofness, heating etc. and remove unsound factors that obstruct students social maturity and build up clean and safe residential environment with good relations with their neighbors.

The purpose of this study was to examine the changes and the characteristics of the attitudes toward children and spaces provided for them. by analyzing people's daily lives in housing spaces and architects' floor plans between the 1920s and the 1960s. Different kinds of data were obtained from a variety of early literature, research reports, newspaper articles, historical documents, and magazines from the period. Findings of this study are as follows: 1. Before modernization in Korea, children had been regarded as immature persons. Confucian ideas of children viewed them as 'small adults' or 'immature adults.' Thus spaces for children's daily lives were neither differentiated from those of the adults' nor deemed important. However, since the Western invasions and colonization by Japan, a remarkable change in the attitudes toward children took place. Children began to be considered a hope for the future as well as members of modem families. In addition, the introduction of the new word, 'eorini (children),' by Mr. Bang Jeonghwan, brought about a significant change in social consciousness of children. 2. The appearance of 'adongshil (children's room)' on architects' floor plans, which was a result of the social critique against androcentrism during the l930s and 1940s, was highly meaningful. The new floor plans not only emphasized rationalization of the space but also upgraded the children's status in the family. 3. Since the liberation (1945), children's space was differentiated from parental spare by the introduction of private rooms and shared spaces. The privacy of each generation was expressed by the division, and the generations were considered equal in this space distribution. In conclusion, the appearance of children's rooms required conflict-laden changes of social ideals and of the family system. It also was a symbol of modernization.
