Objectives: This is a descriptive study which was carried out to identify characteristics of the chronic mentally ill and their families in a rural area and the influencing factors on family burden. Methods : Data was collected for seven months beginning April 1, 1998 by questionnaire from chronic mentally ill patients and their families in two towns and seven townships of the rural areas of Kyonggi Province. In additional to the mental diagnosis of the mentally ill patients, family burden was measured by interviewing the other family members using the questionnaire developed by Pai & Kapur (1981). Of those interviewed, 103 patients were selected for final analysis. Results : Of 103 mentally ill patients, 36.1% of the subjects were not under treatment. In particular, of 29 patients with schizophrenia, 48.3% of the subjects had stopped taking medication and 6.9% of the subjects had never been treated. According to the results of a specialized examination by a psychologist, 81% of patients were in need of Hospitalization. Most primary caregivers were parents. Of the 101 primary caregivers in the study, 39.6% were over 65 years old. In case of death of the primary caregiver, 50.5% of these 101 mentally ill patients would not have anyone to care for them. Of the various kinds of family burden, primary caregivers most often reported psychological stress. Overall, the families of dementia and schizophrenia patients complained of the most family burden. Through univariative analysis, the variables of sex, education and current treatment type of the patients, the relationship with the patient and marital status of the primary caregiver and the number of people living together in the household showed significant correlation with the family burden of schizophrenia patients. Univariative analysis also showed that there were a number of variables which were correlated to the family burden in mentally retarded patients. Concerning the need for mental health services, the most common requests were for entitlement to disability benefits and housing programs. Conclusions: Community mental health services in rural areas must be developed, planned and executed in consideration of the local situation. In particular, the development of various family support programs is needed in order to mitigate emotional, mental and economic burdens and carry out a positive role to care for and rehabilitate patients.

In this research, problems of recent design methods and their improvement for SIP(Soil-Cement Injected precast Pile) in domestic areas were studied by using the properties of load-settlement curves and bearing capacity from field loading tests. Elastic and plastic settlement for total settlement in each loading step of loading tests conducted in domestic areas has been shown to have a tendency. From this tendency and bearing capacity determined by loading tests, it could be ascertained that empirical chart could be an assistant tool in SIP design. It was shown that SIP design using N-value in domestic area with soil condition of granitic type resulted in very conservative hearing capacity. On the other hands, in soil with unfitted geological conditions, the design could be insecure. Also, we could ascertain that Meyerhof's bearing capacity using modified N-value on the tip part of pile was more applicable than recent design method where tip bearing capacity was 20NA$_p$ N-value limited to 50. These results showed that modified design method could be more economic than those in the past because it used pile's bearing capacity unto tolerable load of pile material.

With increasing interest in environmental issues and the quality of surface water becoming inadequate for water supply, the Korean government has launched a groundwater development policy to satisfy the demand for clean water. To drive this policy effectively, it is essential to guarantee the accuracy of sustainable groundwater yield and groundwater use amount. In this study, groundwater use was monitored over several years at various locations in Korea (32 cities/counties in 5 provinces) to obtain accurate groundwater use data. Statistical analysis of the results was performed as a method for estimating rational groundwater use. For the case of groundwater use for living purposes, we classified the cities/counties into three regional types (urban, rural, and urban-rural complex) and divided the groundwater facilities into five types (domestic use, apartment housing, small-scale water supply, schools, and businesses) according to use. For the case of agricultural use, we defined three regional types based on rainfall intensity (average rainfall, below-average rainfall, and above-average rainfall) and the facilities into six types (rice farming, dry-field farming, floriculture, livestock-cows, livestock-pigs, and livestock-chickens). Finally, we developed groundwater-use estimation equations for each region and use type, using cluster analysis and regression model analysis of the monitoring data. The results will enhance the reliability of national groundwater statistics.

There has been no previous study on technology development of large capacity drainage pump for rescue sinking ship in the country. The agricultural drainage pump was widely used for rescue sinking ship but this pump has several problems such as efficiency, low displacement and malfunction in winter. Therefore, this paper proposes to solve the problems for swiftly rescue sinking ship and develops the drainage pump system that has $20m^3/min$ mass flow rate specification at suction head 8 m. The centrifugal pump type the most commonly used in the field of naval architecture and ocean engineering was selected and designed based on the requirement specification. The blade design of impeller was derived from the Stepanoff coefficient and requirement specification and used computational fluid dynamics to review the target mass flow rate according to the impeller RPM at design operating conditions. We also performed structure analysis of the impeller to find structurally vulnerable points for the pump in service and completed the theoretical design of drainage pump system.

Various housing measures are needed for the rapidly aging society of Korea. In particular, the welfare policy for the elderly has changed towards the community care. Taking this fact into consideration, it is necessary to have the establishment of a system that offers the elderly appropriate welfare services at their appropriate residence (ageing in place) for the effectiveness of the community care. In this aspect, there are a number of implications to Korea to study merits and demerits of the Health Facilities for the Aged (HFA) in Japan. The society of Japan has been rapidly aging since 1970, and Korea is to face the same situation. As for the data of this study, a total of 2,393 facilities (as of November 1999) mentioned in the annual report of the Japanese Ministry of Health, Labor and Welfare were classified based on types of their establishment: (1) free-standing structures (603 facilities); (2) annexes to hospitals (981 facilities); (3) annexes to welfare facilities (511 facilities); and (4) annexes to clinics (298 facilities). Next, 239 facilities were selected through taking a sample of 10 percent from each type of the HFA mentioned above. This was done through the random sampling method with the computer program of MS EXCEL. The Implications of the results of analyses are as follows. First, most of the health facilities were planned with the scale that was larger than the scale of standard special nursing homes in terms of the total floor area. Precise equations that were to obtain precise results of the scale of the HFA and the appropriate number of residents were obtained through the method of the regression analysis. Korea and Japan have similarities in terms of culture, society and family relations; however, the two countries also have differences in terms of the application of laws on the establishment of houses, hospitals, and welfare facilities. As for planning the scale of the HFA, the realities of Korea should be considered. Second, as for the functional aspect of the HFA with a condition of returning home, the place before and after the HFA showed the pattern of 'from a residential place to a residential place' and 'from a hospital to a hospital.' This reveals a close correlation with the types of the HFAs and operational ways of the facilities. Its cause is considered to be the aspect of the operation and management of the HFA rather than the aspect of its function of providing services in association with medical and health facilities. Therefore, when intermediate welfare facilities are considered in Korea, it is strongly advised to consider the problem of annexes to other facilities and efficiency of sharing of the facilities in terms of its operation and management.

The number of Aged Apartment units is expected to increase as time went on. Living standards are getting better and they want a new apartment space as the economy progresses. Therefore, it is necessary to prepare for the increasing remodeling market through the feasibility evaluation method that can be applied to the remodeling project of the apartment house. The purpose of this study is to analyze the social pricing factors affecting the Officially assessed individual House Price for the analysis model of commercial house remodeling. The collected samples were analyzed using multiple regression analysis of 350 prices included in 127 lots. Middle school level, high school level, total number of households, and floor area ratio were extracted. As a result of comparing the Officially assessed individual House Price by applying to the remodeling case, the difference between the existing Officially assessed individual House Price and the improvement Officially assessed individual House Price is different. The accessibility with the subway station is included in the land price, and there is no change in the number of stories and directions because it is customized remodeling. There was a difference in the disclosure price depending on the type of factor extraction by the evaluator in a batch application of the disclosure price factors. The research can be used as a model for future remodeling business feasibility analysis.

This is the forth consecutive study on the 'Standardization of Measurement for Korean Kitchen Work Centers and Cabinets for Future Design Criteria'. The purpose of the present research was (1) to classify homemakers' representative like styles related to the kitchen, (2) to examine homemakers' present concerns on the kitchen space, and (3) to investigate homemakers' desire and preference on the kitchen space. Twenty two hundred homemakers of upper and middle class residing in Seoul, Busan, Daegu, Incheon, Gwangju and Daejeon were selected for the survey and 1,843 among them were used for data analysis. Data were selected for the survey and 1,843 among them were used for data analysis. Data were analyzed using the SAS program package. The statistics used were frequency, percentage, mean, factor analysis, F-test, Duncan's multiple range test, X2-test, cluster analysis. Findings from the research as follows: (1) Four factors were found as indicaters of the life style; values on the household work, desire on social function of the kitchen, degree on cooperation of family members on the household work, and convenient management. It was noticeable that homemakers had positive responses in terms of desire on social function of the kitchen and degree on cooperation of family members on the household work. Homemakers' life styles related to the kitchen space were classified into 6 categories. (2) Relatively a few respondents answered that the kitchens were very well furnished. If, however, the economic conditions become better, substantial number of them wanted to invest for better kitchen following the one for living room. (3) It was found that most respondents preferred the arrangement of space, where dining and kitchen in one space, and a hard wall or soft treatment was between living and dining/kitchen area. (4) Many respondents desired pantry, utility and laundry area be near the kitchen or in the same space with it, thereby forming a utility core in a housing space.

Social enterprises that are solving pressing global issues and providing services such as micro-finance, affordable housing, appropriate technology and education for the 'bottom of the pyramid' as well as cultural and community-related businesses that improve the 'quality of life' within a society are the target of impact investments. Among them, a capital financing is one of the most important factor in founding and fostering of social enterprise. However, the capital market for social enterprises in South Korea are not yet sufficiently developed. The Britain and U.S.A. attempted to solve the social problem by the introduction of the social innovation credit model, for example, social impact bonds(SIB), Big Society Capital, DBLIF, and ACCION International, which are considered as an innovative new financing instrument for social program. Instruments are being attempted for the first time in Britain and America. This study have two purposes. The first purpose is abstracting the institutional mechanism for introduction of impact investment such as SIB and DBLIF case in Britain and U.S.A.. Second, analyzing type and mix of policy instrument on impact investment from the perspective of policy instrument.

An optical microphone based on a dual-core fiber collimator and a membrane type micromirror serving as an optical head and a reflective diaphragm respectively was implemented. The micromirror diaphragm is suspended by a thin silicon bar linked with a frame, thus it is subject to a displacement induced by acoustic waves. The optical head incorporating two collimators integrated in a single housing gives light to and receives it from the diaphragm, rendering the optical microphone structure simple and compact. This dual-core collimator having a slowing varying beam profile facilitates the initial alignment of the optical head with the diaphragm, especially the distance between them. For the assembled microphone, the static characteristics were investigated tofind the operation point defined as the optimum distance between the head and the diaphragm, and a frequency response with a variation of about $\pm$5 dB for the range of up to 3kHz was achieved.
