Lower birth rate and higher elder people are serious social problem in Korea. In 2003, the total birth rate is 1.19 per person, that record is lowest among OECD country. In 2005, Korea has been the aging society with 9.0% in aged population rate. Increasing of aged population results in elder estrangement and confliction with other generations. The social problem can be solved in some degree by improving housing environment and many kinds of welfare program. This study suggests a solution of the problem by applying community space located on ground level floor. The ground level floor of apartment has many physical benefits like connection to the earth, extension, safeness for the aged and child. in case of the National Rental apartment, small residential area and high rate of elder, child, the disabled make the ground level floor useful space for community. According to case study, almost the National Rental apartment hasn't enough facilities supporting various generations and don't supply comfortable environment. So, this study presents how to design the National Rental Apartment's community space located on ground level floor.

This study evaluates the seasonal performances of the horizontal-type geothermal heat exchanger(HGHEX) installed into the foundation slabs of the complex building located at Seoul. The geothermal system is consisted with totally 31,860m long HGHEX, 16 GSHPs (Ground-source Heat Pump) and 8 circulation pumps. This system supplies cooling and heating to the lobby(F1) and the common spaces(BF1). The average heat exchange temperature differences are $2.7^{\circ}C\;and\;2.5^{\circ}C$ in the summer, $1.5^{\circ}C\;and\;0.5^{\circ}C$ in the winter for the F1 and BF1 respectively. From these results, approximately 400Gcal and 180Gcal of geothermal energy are assumed to have been used during the summer and winter seasons respectively. As a conclusion, the geothermal system is reviewed as a effective utility for heating and cooling at the point of seasonal performances.

Until now, several comparative approaches were developed within the studies of Korean, Chinese, and Japanese traditional housings. In those studies, however, each space in the traditional houses was only treated in individual and fragmentary manners, and they lacked the interpretation of the topological attribute of each space within a holistic structure organized by unit spaces, and of the cultural-behavioral meaning of them within a holistic space-use pattern of the housing. The topological attribute and behavioral meaning can be analyzed and interpreted with the quantitative spatial analysis method such as Space Syntax. This study aims to analyze the traditional housings in Korea, China and Japan in the holistic aspect of spatial structure using Space Syntax, and to compare the analysis results with relating the structural attributes to the space-use pattern. In this study, the 'Banga' in Chosun era, the 'Siheyuan' in Ming-Ching era, and the 'Shoinzukuri' in Edo era were selected as the analysis subjects. The integration indices were calculated from the convex maps representing the subjects, and the common and different attributes of the three subjects were defined through comparative analyses.

In Korea, multi-functional senior residential complexes have become very popular since the end of 1990 by integrating the functions of nursing homes and health care facilities, so that the elderly can maintain their regular healthy life and receive health care when needed depending on their aging stage. Accordingly, it is increasingly important to conduct research on such multi-functional residential facilities. In this study, 6 cases of Korean senior residential complexes and 6 cases of comparable Japanese facilities, which were built earlier than Korea, are compared, and the following results are derived from the comparison. 1. In terms of the shared space, the parallel type and the unified type are found to share more space among complex types. Especially, the low-story concentration type and the eccentric type are found to share space the most. 2. In Korea, an average shared rate is found to be 46.8%; and the rates of a supplied-space, a common-shared-space, and a maintenance-space are found to be 29.73%, 36.33%, and 32.93%, respectively. In Japan's case, an average shared space is found to be 22.31%; and the corresponding rates for the above 3 spaces.

Nowadays, the constructions of dams are being issued by the public due to the preservation and protection of nature considered more important than development. These social phenomenon can not be evitable due to arguing the both attitudes, preservation and development of nature. However, There are possibilities to make an agreement with the compromise between the two sides. The common goals of the attitudes are concerning human beings and their life quality. In this atmosphere, the exhibition hall of dams is very important to lead the agreement of both groups because the spaces not only provide contents to compromise by showing positive factors of dams, but present condition of using water as natural resources. The purpose of this study is based on the effect of the applied media in an exhibition hall as presenting education and enlightenment factors. To examine the effect, this study categorizes the existing media by communication types firstly. Secondly, based on the categorization, existing media of each dam exhibition hall are analyzed by numerical way. Thirdly, the general characteristics of applied media are defined by integrating the spatial contents and media. The data from the study are effective to provide the basic data for following design works for the exhibition space.

Small park in the community is a public asset that is commonly used by the residents daily and performs an important role to activate the community. The purpose of this study is to draw a small park plan through community participation. In concrete, this study tries to find out the demand of the residents about their small park plan, observe the changes in their demand in the process of debate and analyze the effect of the residents' participation. Small group workshop method was adopted in the study and three groups were set up and surveys were made in two stages. Two dimensional pictogram cards and three dimensional digital park formation tools were used. The results of workshop study indicated as follows: Firstly, residents wanted to have community farming garden, green house and flower garden to grow plants, natural walls and safe resting facilities. Secondly, individual and diverse opinions presented at first could be converted to common opinions through mutual exchanges of opinions in the process of debates. Thirdly, digital park formation program functioned well as an effective visual tool to draw the attention and quick responses of the residents and to reach an agreement. It is expected that the results of this study show the effectiveness of residents' participation tools in the process of drawing agreements in the community society that requires the residents' demands and agreement and this study will be usefully utilized in planning community spaces with residents' participation hereafter.

By the year 2050, the world population is set to increase to 9 billion people, of which 66% will be living in cities. It is argued that this will inevitably lead to further urban densification and soaring, inhumane and dense vertical environments. However, innovative and disruptive technologies impacting all realms of life means that we will also live, work, play, learn and make in novel ways, the beginnings of which are already becoming evident. These present opportunities for reimagining city environments, and in particular tall buildings, with a focus on reducing redundancies and re-appropriating existing buildings, creating novel hybrid environments, incorporating green and social democratic spaces, and integrating multiple modes of transport. This paper examines how vertical cities may perhaps be dense, resource efficient, and yet humane, presenting three possible scenarios for Singapore's context, which are, however, common to many Asian high-density urban environments. The scenarios presented are the outcome of Final-Year Thesis Projects undertaken by final-year architecture students at the National University of Singapore (NUS) in 2017.

Communal places for parents to take child-care are very important in activating cooperative child-care(CCC). Therefore, Jeju Special Self-Governing Province has been operating Cooperative-Childcare-Places(CCPs) since 2016. This study analyzed the operational status of the CCPs and presented the model type to provide data for the activation of CCC. Qualitative analyses were applied to the results of interviews with 10 staff members. The common task they considered difficult was recruitment, and there was a big difference in the operation of the regular program depending on the competence of the staff in charge. The lack of support systems, such as education and consulting, has made it difficult for the staff to do their work. Additionly, four models of CCPs were found, a resident self-governing type, a workplace type, an institutional type, and a rural complex type. In conclusion, CCP spaces should be planned and facilities created with a focus on the needs of child-care activities. Second, the role of staff in helping to organize the parents' self-governing committee is crucial. Third, it needs to establish a support system to strengthen the capacity of the staff members.

Sensor networks are composed of provide low powered, inexpensive distributed devices which can be deployed over enormous physical spaces. Coordination between sensor devices is required to achieve a common communication. In low cost, low power and short-range wireless environment, sensor networks cope with significant resource constraints. Security is one of main issues in wireless sensor networks because of potential adversaries. Several security protocols and models have been implemented for communication on computing devices but deployment these models and protocols into the sensor networks is not easy because of the resource constraints mentioned. Memory intensive encryption algorithms as well as high volume of packet transmission cannot be applied to sensor devices due to its low computational speed and memory. Deployment of sensor networks without security mechanism makes sensor nodes vulnerable to potential attacks. Therefore, attackers compromise the network to accept malicious sensor nodes as legitimate nodes. This paper provides the different security models as a metric, which can then be used to make pertinent security decisions for securing wireless sensor network communication.
