THE author conducted a field survey form Feb.1, 1973 to March 31, 1973 in the Busan area, standing six "institutions" where mentally ill patients are kept. These six institutions are registered at Busan Government, but are not regular hospitals. There suits of these investigation are as follows: \circled1 There are six institutions. which are registered at Busan City Government. All six are operated by layman who have little psychiatric knowledge and little human is tic motivation. \circled2 These institutions are allegedly to promote the welfare of the mentally sick. However they give little help for the patients. And they do not even have a resident medical person. The staff of those places will not accept professional medical help, and try to keep all information secret. \circled3 The finances are largely composed of patients′fees and partially from city′s help. The buildings are of high quality compared with the poor therapeutic situation. There also exist factors which make the patients worse, i,e. very small room space, compelling the patients to sit in a uteral position. This situation makes them worse and more autistic. \circled4 At the time of this survey, those lucrative overcrowded six institutions had 1.000 patients. At the same time the legitimate hospitals in Busan area had about 200 patients, \circled5 In my opinion, the City Government must take a more positive policy for the mentally ill patients, instead of the passive attitude which has held till now. And most of all, these patients must be medically and humanistically helped, instead of being left in a forgotten, depressed snake pit.

Recently, landslides frequently happen at a natural slope during period of intensive rainfall. With rapidly increasing population of steep terrain in Korea, landslides have become one of the most significant natural hazards. Thus, it is necessary to protect people from landslides and to minimize the damage of houses, roads and other facilities. To accomplish this goal, many landslide prediction methods have been developed in the world. In this study, a simple landslide prediction system that enables people to escape the endangered area is developed. The system is focused to debris flows which happen frequently during periods of intensive rainfall at steep slopes in Kangwondo. This system is based on the wireless sensor network that is composed of sensor nodes, gateway, and server system. Sensor nodes that are composed of sensing part and communication part are newly developed to detect sensitive ground movement. Sensing part is designed to measure tilt angle and acceleration accurately, and communication part is deployed with Bluetooth (IEEE 802.15. I) module to transmit the data to the gateway. To verify the feasibility of this landslide prediction system, a series of laboratory tests is performed at a small-scale earth slope supplying rainfall by artificial rainfall dropping device. It is found that sensing nodes installed at slope can detect the ground motion when the slope failure starts. It is expected that the landslide prediction system by wireless senor network can provide early warnings when landslides such as debris flow occurs, and can be applied to ubiquitous computing city (U-City) that is characterized by disaster free.

The purpose of this study was to investigate unit care characteristics of large skilled nursing facilities for the elderly, which are located in city areas, and to discuss the way of encouraging home-like atmosphere in perspective of spatial unit. First of all, the analysis of five facilities opened before 2002 was performed, based on previous studies, to compare with them opened in recent 5 years. Most of the previous facilities did not have differentiation between their residential and nursing units, and the number of residents in each unit were excessive in comparison with the standard limit(12-28). On the contrary, the facilities established in recent 5 years had systematic spatial unit structure. The residential units had basically rooms and spaces for small group and the number of elderly residents per unit was appropriate on the basis of standard limit which was suggested by Kwon(2002). The nursing units were consist of nursing station, 2-3 residential units, spaces for large group of residents, hair dressing, nurse, living assistant, bathing, storage and etc. But, there was a problem In space usage even though they have distinct unit care systems. Some spaces for groups were empty without residents, furniture, and other equipments, which were necessary for unit care.

Since then where the public housing comes in into Korea many there was development and change. The Mapo apartment in Seoul which is built at 1962 is the first apartment and case of Jeollabuk-do before being built at 1978, the Dongyang apartment Jeongju is the beginning. Before the residential supply ratio which gives already passes over 100% and of 80% or more of the house which is supplied is composed with the public housing. Therefore the expansion which is quantitative increased enough and also the degree of satisfaction improved about the people who lives in the house. From the research which sees consequently currently in the object satisfaction under investigating boil the specialists who from the small and medium-sized town and city have a many experience from construction field about the house. The result in future there is the goal provides the fundamental data which the quality of the house presents the direction which will advance about the public housing with base and improves.

In recent years, the change of urban function and the decrease in birth rate have given rise to merge, abolition and relocation of the existing schools. This study explores the possibilities for various land utilizations of disused school sites, using the trial case of 'M' elementary school at Bu-pyung Gu in Incheon Metropolitan City. 'M' elementary school has recently happened to need no more land to build another school because of decreasing the number of students. Firstly, it studies the land reuse theories in city, the development methodologies of disused sites and the legalistic and political authority and limits. It analyzes the urban spacial values and roles, such as the educational roles, spacial functions and development values of the land. In addition, this study make a questionnaire of local residents to converge the public opinions on the utilization of disused school site. Finally, it proposes the principal direction for the effective appropriation and an alternative for exploitation of school site targeting disused school site of 'M' elementary school.

The management of power factor(PF) in the distribution line is treated according to the measurement a month about the feeder unit at the substation. In Korea, we have not researched into power factor in distribution system due to it's less weight. The reactive power in advanced countries is controlled automatically by the compensative condenser switch on/off under the monitoring. This paper first presents the optimal condenser position and proper capacity by lagrangue factor ${\lambda}_{Q}$ which is the line loss index about reactive power unit. Therefore, the largest ${\lambda}_{Q}$ node is the condenser injection point and we find out the best condenser capacity when the line loss is saturated by the moderation of condenser volume. By this method, we suggest 0.6% uprising PF by injection of 15 kVA condenser. Additionally, PF is analysed into 5 areas; large city, middle city, small city, farm village, fishing village by the use of Power Platform which is classified the same concept of the low load management in KEPCO. Two feeders of each area are selected by the worst results of PF in specified areas.

Recently the number of women's hospitals of a small scale are increasing in seoul and the other cities although the surroundings of these sites are so inferior. Those hospitals need the space of comfort as like family home. This study suggests that the encirclement space is one of the design methods to make comfort to patients. The encirclement is the form of hugging a baby to a mother's arms. Analysing six woman hospitals, encirclement space is categorized about the six types of square, open square, right-angled, linear, dispersed, etc. The characteristics of "right-angled" is featured as the form of L, and "square" type is characterized as the relationship of functional circulation among doctors, nurses and patients. And all types are organized as the relationship between the encirclement space and the enclosed space about how the functional space and the comfort space are made up. The properties of encirclement space are appeared by the interactions about function, circulation, sight, form, access, recognition through transparent, three-dimensional experience, etc. Encirclement space is recommended as a vital factor to make comfort space for designing women's hospital in city.

The Yocheon is an upper stream of Sumjin river, passing through Namwon city. The water temperature of the stream increases from upper stream to downstream. The amount of COD, T-P, T-N, EC, TDS abruptly increases at measuring site 8. Whereas, the pH and DO level abruptly decreases at this site. At this point, the Yocheon river joins another small stream passing through the central part of Namwon city. At a further downstream pass site 8, the amount of COD on April and June (a dry season) is on third grade of water quality for lacustrine. This contamination suggests that sewage from the Namwon city provide COD, T-N, T-P into the stream. At point 2, the high amount of T-N indicates that the upper stream is contaminated by agricultural activity.
