Changes in the population structure caused by a decrease in the birthrate and an extension of life expectancy cause problems in utilization inefficiencies of closed schools and shortage welfare facilities for the aged. The closed schools have location characteristics that are close to the existing residence and facilities such as land and school buildings, so it is expected that the schools will be used as welfare facilities for the aged in the community. The purpose of this study is to compare and analyze the facility characteristics of closed schools in northern Gyeonggi-Do and present the types of aged welfare facilities that can be built, providing basic data for developing customized aged welfare facilities. The results of this study are summarized as follows: 1) The proportion of aged people in northern Gyeonggi-Do is higher than in southern Gyeonggi-Do, but welfare facilities for the aged are insufficient, so it is necessary to expand welfare facilities for the aged in northern Gyeonggi-Do. 2) Urban areas such as Paju and Goyang City have a lot of residential proximity, Dongducheon and Yangju have a lot of residential proximity, while schools located in urban and rural areas such as Yeoncheon have a lot of residential proximity. 3) Closed schools in urban areas such as Goyang City and Paju City are desirable to use them as residential facilities for senior citizens, day and night protection and short-term protection facilities, while closed schools in Namyangju City, Pocheon City, and Gapyeong County are desirable to use them as senior citizen centers and medical welfare facilities.

Most of construction at urban area is now undertaking a redevelopment because currently the most of city is full. But the research about the collision of urban tissue at urban redevelopment area are very limited and there are many issues at urban redevelopment area. So the purpose of this study is to analyze the collision between different urban tissue at urban redevelopment area and suggest proper method for urban redevelopment. The area inside of four main gates, especially Chung Jin, Gong pyeong, Mu gyo- Da dong district are selected to analyze because the area inside of these gates is the oldest urban redevelopment area and each of them has a different redeveloped method. And current status of research area's urban tissue and collision situation are analyzed by macro and micro scale of view. The results of this study were as follows; Ignoring the timeline of the urban redevelopment process can be a major issue in collision between urban tissue. Therefore, the consideration of intermediate stage of redevelopment process is needed by making public area, a temporal use of vacant lot and changing architectural elements can make a harmony between different urban tissue.

Rapid urbanization and social development have brought about changes in family structure. In urbanized areas, recently the number of dogs that are a majority of companion animals has increased significantly in Korea. Consequently, a lot of friction between the general public who are not fond of dogs and dog owners in public places such as parks has been happening. A lot of countries that are taking a lead role in animal welfare have built dog parks that the general public and dogs can enjoy together. This research starts with the realization that the concept of 'dog park' needs to be introduced in Korea as more and more Koreans own dogs and other pets. This research aims to provide guidance for dog park planning by drawing planning items and analyzing the needs of each item. Total 56 planning items including dog zone, dog playground, and dog training facility, are drawn in this research. There are differences in the needs according to sex, age and the amount of time they spent with their dogs, however overall there is the highest needs in separated area for dogs in parks.

Nuclear power generation is very dangerous in occasion that skirt of structure by earthquake although it is high effective generation that can make a lot of energies with few raw material. when design, it must consider a lot of problems caused by an earthquake. The seismic analysis of the structure has been great concern in the engineering society with an effort to reduce the severe damages from an earthquake. So the earthquake resistant design is one of the crucial design procedures of a gate valve used in nuclear power generation. The gate valve which has the contact area between stem and bellows. Because of the contact area. The gate valve should be given high stress and frictional wear. In this thesis, Considering the gate valve which has some contact distance between stem and bellows. The gate valve which has some contact distance is analyzed by a commercial FEM code of Ansys and Then compared to the gate valve behavior which doesn't have contact distance.

In the historical city center where overall development has not been made, it is not difficult to observe the asp ect of the urban change process over time accumulated. Seochon(西村), which collectively refers to 13 legal dong s in the west of Gyeongbokgung Palace, is also considered a representative historical village with high value as a historical and cultural cityscape because of historical context remains throughout the lot. Therefore, research ex amining the process of changing parcels in this area is useful for a more three-dimensional understanding of the presence of several layers of time. In this study, relationship between the opening time of each road, the river co ver process, and the current building establishment process is examined using maps after the pre-modern period and modern era. In addition, to examine the specific change process of individual lots using the old land register, building management ledger and cadastral map.

National Assembly is a constitutional institution that is required to first consult the will of the people and it should do its effort continuously so that security of citizens using parking lot would be enhanced at the same time while improving parking service in order to increase customer satisfaction of the people. Under this recognition, in this study, Doonchi parking lot of National Assembly under consigned management was first reviewed in a perspective of criminal prevention through environmental design(CPTED) and particularly, fence installation and reinforcement work for securing 'territoriality' and operation of all round shooting camera and installation of No-trespassing warning board at entrance were suggested. Second, it was recommended to change independent control system in which CCTV security system of National Assembly Doonchi parking lot is operated separately from National Assembly safety situation room and integrate it with National Assembly safety situation room(revised to double safety system) and performance of CCTV camera was made to be increased to over 2m. In addition, video recording mode was converted to NVR mode for application to IP camera in the future and in order to avoid dead zone of security monitoring area and based on site inspection result, addition 3 places of newly installing CCTV were indicated. Third, it was recommended to introduce parking fare billing and management system through unmanned equipment in parking lot management and operation.(specialized management of professional parking service provider was reviewed). By doing so, risk of cash handling by charging personnel was removed by reducing current 7 working personnel to 3 and particularly, by converting parking lot management mode being operated temporarily from 9 A.M. to 9 P.M. at present to 24 hours operation mode and providing more specialized parking service, citizens visiting National Assembly were provided with convenience and image of National Assembly was also enhanced. This study was carried out in parallel with various literature and case studies, including data from the Office of the Defense Protection in the National Assembly.

Time goes on, Ad Hoc network is hot issues. So far, there are a lot of protocols have been proposed for Ad Hoc routing protocol to support the mobility. This paper presents an enhanced DSDV(Destination-Sequenced Distance Vector) routing protocol which nominates one node to take care of a specific area. Simply Area-Aware(AA) DSDV routing protocol has one nominee to take care of some area. It has two jobs. One is to take care of its neighbour and another is to transfer the routing table to its other node as it works. It is called as Area Nominee(AN). The new scheme extends the routing table to include the nominee in the area. The general node is the same as the previous DSDV routing protocol. In the other hands, the node which is nominated has two routing protocols. One is for Regional Routing(RR) table which is the same routing table in DSDV. Another is Global Routing(GR) table which is about the area round its area which it cares nearby. GR table is the table for the designated node like the nominee. Each area has one nominee to transfer between ANs. It has only nominee's information about every area. This concept decreases the topology size and makes the information of topology more accurate.
