The Homeshare Program was promoted to solve the housing problems of the elderly and the young by the Seoul City in 2012. The elderly can provide spare rooms in their homes for the young at low rental fees, and the young can provide daily services to the elderly, cooperating with each other for better housing and life. The aim of this research is to find out how the participants use the shared space and what kinds of activities are shared in homeshare. This research uses case studies, which interviews 10 cases of homeshare in Seoul. The contents of the research are investigated shared spaces of the elderly, and analyzed contents of interaction lives in shared spaces. The elderly experience loneliness while living alone, and having someone to live with gives them comfort and a sense of security, and this is one motive for participating in homeshare. The elderly and the young share many equipment and shared activities and interactions in shared space. The homeshare program makes it possible for the elderly to aging in place and have interactive relationships with different generations. Therefore, homeshare may the formation of a new family, and new dwelling utilizing the elderly's house.

This study explores the patterns of housing-related attitudes and the kind of needs for shared community spaces among small-sized apartment housing dwellers. The major findings are as follows. The majority of the dwellers are in a strong need of common spaces. especially for children's activities. social gathering and physical exercises. Housing consciousness can be grouped into 4 categories the propensity to making up common society. the propensity to pursuing the quality of neighborhood. the propensity to orienting natural environment. and the propensity to participating in community. Families with children in primary school are more likely to get involved in the community and the common society than those with children in high school or those in the stage of launching a family. The propensity to making up common society and pursing the quality of neighborhood have stronger impact on needs for shared community space. This study reveals that the sense of community orientation is the most powerful predictor variable for shared community space needs.

The number of household living alone including young single adults has gradually increased. The purpose of this study is to examine the demand on housing options, additional space, shared space, community facilities, housing service for young adults living alone including college students. A total of 180 questionnaire were collected and analyzed. For housing location, commuting distance is the most important feature and amenities are the second important feature. For additional space, there is a significant difference between male and female single residents. Female residents want to install dress room most while male adults want to have a study room. For the shared house option, single adults concerns housing fee and living cost most. However, female adults concern safety and security issues much more than male ones do. The degree of preference to community facilities varies between male and female single residents. The findings suggest more differentiated approaches are needed for alternative housing options for male and female residents.

Avionic databuses fulfill a critical function in the connection and communication of aircraft components and functions such as flight-control, navigation, and monitoring. Ethernet-based avionic databuses have become the mainstream for large aircraft owning to their advantages of full-duplex communication with high bandwidth, low latency, low packet-loss, and low cost. As a new generation aviation network communication standard, avionics full-duplex switched ethernet (AFDX) adopted concepts from the telecom standard, asynchronous transfer mode (ATM). In this technology, the switches are the key devices influencing the overall performance. This paper reviews the avionic databus with emphasis on the switch architecture classifications. Based on a comparison, analysis, and discussion of the different switch architectures, we propose a new avionic switch design based on a time-division switch fabric for high flexibility and scalability. This also merges the design concept of space-partition switch fabric to achieve reliability and predictability. The new switch architecture, called space partitioned shared memory switch (SPSMS), isolates the memory space for each output port. This can reduce the competition for resources and avoid conflicts, decrease the packet forwarding latency through the switch, and reduce the packet loss rate. A simulation of the architecture with optimized network engineering tools (OPNET) confirms the efficiency and significant performance improvement over a classic shared memory switch, in terms of overall packet latency, queuing delay, and queue size.

In ubiquitous computing, shared environments adjust themselves so that all users in the environments are satisfied as possible. Inevitably, some of users sacrifice their satisfactions while the shared environments maximize the sum of all users' satisfactions. In our previous work, we have proposed social welfare functions to avoid a situation which some users in the system face the worst setting of environments. In this work, we consider a more direct approach which is a preference based clustering to handle this issue. In this approach, first, we categorize all users into several subgroups in which users have similar tastes to environmental parameters based on their preference information. Second, we assign the subgroups into different time or space of the shared environments. Finally, each shared environments can be adjusted to maximize satisfactions of each subgroup and consequently the optimal of overall system can be achieved. We demonstrate the effectiveness of our approach with a numerical analysis.

The aim of this paper is to find out different preference of common spaces and shared activities in senior cohousing community between regions in Korea: Seoul and other cities. Social survey was conducted nationwide and the respondents were 50s only, since they are the generation who will face to elderly housing subject within 10 years in turbulent Korean society. Collected data, about 1000, were analyzed by SPSS program using frequency, percentage, and Chi-square test. In summary, respondents mostly would like to move to senior cohousing on circumstance when they remain alone without big difference between regions. Loneliness and housekeeping were considered as the most difficult issues for the elderly to manage by themselves. Among common spaces, exercise room was the most preferred space to meeting room and kitchen. Exercise room was more preferred in Seoul than in other cities, on the contrary meeting room was evidently less preferred in other cities than in Seoul. Regarding shared activities, resident meeting, gardening, and common meal were revealed as less preferred activities than hobby exercise and tea meeting. As a conclusion, I would like to propose that a big common living room is better to be designed for meeting room cum dining and gathering room with flexibility in order to give residents chances to know each other more often. And since common space and shared activity show different preferences by regions, those are to be designed and planned reflecting region's different circumstance.

The fundamental concept of shared street is integration of traffic and pedestrian activity as a positive principle for street planning. Shared streets have been very successful in several countries in terms of reductions in traffic accidents, increased social interaction and children's play, and a high degree of satisfaction by the residents. This paper proposes the concept of shared street to solve traffic problem without reorganizing traditional street structure and without disturbing traditional function of street as a living space for residents. And this study examines detail concepts and techniques of the shared street and applies them to a pedestrian oriented streetscape design of "Ducksugung-Gil," Seoul, which was one of the most important streets in Korean modernization history.n history.

Purpose: Recently, Housing area plan has tried to reflect a public space of various forms. However, most of cases are indiscriminately developments, which don't reflect the diverse needs of residents. In addition, a subject of the public space is not clear and consistently stable of the management, so the residents don't have an interest enough to take advantage of it. Method: In order to make a plan of the public space of a residential complex, an architect designer needs to take a few things into consideration. One is a physical facility in needs. And other one is a management of keeping a social place stably and consistently, which allows residents to be able to interact with each other. It should be regarded for residents to form a sense of belonging, while minimizing the interface friction. When all these problems are fulfilled, an interaction will be made to improve the quality of the living environment. Result: Therefore, in this study, it is necessary to define the meaning of territoriality of the external public space of housing complex. This study makes it possible to improve the relationship of neighborhood and the quality of the life for the residents, depending on the time. This is the first step as 'the research for the territoriality of the external public space of housing complex', in order to define about the concept, function, characteristic of territory(the base of territoriality) and to establish the territoriality that can form the physical or psychological boundary in public space.
