This study was conducted to provide a foundation for housewife-consumer education programs appropriate in the information society. For this purpose, the authors reviewed existing literature, analysed consumer counseling cases, and conducted focus group interviews. The need for housewife-consumer education was illustrated, and desirable educational contents and methods were proposed. The existing housewife-consumer education programs did not work effectively because the contents were too general, and mostly structured with non-interactive one-way lectures. More effective programs should be designed to accomodate the educational purpose and contents which fitted with the specific needs of housewives as the representatives of the family consumer units. It should also take the family life cycle stages into consideration. The education programs would work better when they were oriented more toward actively participating, locally-based spontaneous small-groups.

This study has been performed to analyze impacts of urban vs rural residence on later life. In this study, 329 Koreans aged 60 or more were interviewed for their current sociodemographic status and daily life styles. The results are drawn as follows: 1. There is no regional impact on birth order; rate of those born as the first child was not significantly different over regions. 2. For the household composition, the rate of three generations was significantly higher in rural areas than in urban areas. 3. More than 85% of the subjects lived in owned homes in rural areas, while 77% did in urban areas. 4. More than 89% of the subjects lived in single-structured homes in rural areas, while only 45% did in urban areas. The results indicate that in planning public housing for the aged, more social spaces accommodating grandchildren and ownership units need to be allocated for rural facilities. In addition, it is recommended that daily activity schedules need to be differentiated so that rural residents have meals and houseworks earlier than urban residents.

In most cases of multidimensional scaling(MDS), the distances or dissimilarities among units are assumed to be symmetric. Thus, it is not an easy task to deal with asymmetric distances. Asymmetric MDS developed so far face difficulties in the interpretation of results. This study proposes a much simpler asymmetric MDS, that utilizes the notion of "altitude". The analogy arises in mountaineering: It is easier (more difficult) to move from the higher (lower) point to the lower (higher). The idea is formulated as a quantification problem, in which the disparity of distances is maximally related to the altitude difference. The proposed method is demonstrated in three examples, in which the altitudes are visualized by rainbow colors to ease the interpretability of users.

The article reviewed the elderly health care management problems in policy development issue of the nation. Policy of Korean government on elderly health care has still not yet developed. The main stream of policy which is effective on elderly welfare policy is 'Elderly care are responsible by their families'. Now only those aged whose family members are not able to take care of their parents are receive custodial care at the non-profit nursing homes. This article examined the main stream policy in pro and cons aspects in relation to social changes such as: demographic changes. family structure changes. attitude changes. health care delivery system. and political settlement view points in connection with medical insurance program. Finally. a model for the elderly health care management was proposed which will provide chronic care services at the community level. such as nursing homes. day care centers. day hospitals, respite care units, and special care institute for dementia.

The recent development of efficient thermal prime movers for distributed generation id changing the focus of the production of electricity from large centralized power plants to local generation units scattered over the territory. The scientific communality is addressing the analysis and planning of the distributed energy resources(der) with wide spread approaches, taking into account technical, environmental, economical and social issues. The coupling of cogeneration system to absorption/electric chillers or heat pumps as well as the interactions with renewable sources, allow for setting up multi-generation systems for building cooling heating and power(BCHP) systems of different energy vectors such as electricity, heat(at different enthalpy levels), cooling power, hydrogen, various chemical substances and so forth. Adoption of the composite multi-generation systems may lead to significant benefits in term of higher efficiency, reduced $CO_2$ emissions and enhanced economy. This paper outlines the main aspects of the BCHP system framework, illistrating its characteristics and summarizing the relevant distributed multi-generation structures.

Subjects were 15 teachers and 143 children at 15 child-care centers in Seoul that varied by quality of care. The Child Care Program Observation Scale(Rhee et at., 2003) was employed to observe the quality of the centers. Information on teachers' participation in play was collected by 20 units of observation for each teacher using a rating scale developed by the author. Children's behaviors were observed with time sampling method in 12 categories of play behaviors based on Social and Cognitive Play Scales(Rubin et al., 1978). Children's play behaviors varied by quality of child-care centers and teachers' participation in play. When child-care quality was high, teachers' participated actively in children's play and children showed developmentally appropriate play behaviors.

UIS사업의 결과로 나온 공간데이터의 경우 막대한 비용투자에 비하여 활용의 정도는 기대에 미치지 못하고 있으며 공간데이터의 활용확대를 위하여 데이터의 효율적 관리 및 공유체계의 확립을 위한 노력은 반드시 필요하다. 본 연구는 지방자치단체내에서 공간 데이터의 효율적인 관리 및 공유체계확립과 공간데이터의 활용 확대를 위하여 사회연결망 분석 및 계획행동이론을 적용하였으며 부산광역시 공간데이터 사용 공무원을 대상으로 분석결과 공간데이터의 공유에 영향을 미치는 장애요인에는 데이터 사용자들간의 태도 및 주변과의 관계에서 발생하는 비기술적 장애요인의 비중이 높게 나타났다. 또한 데이터의 제공위치에 따라 공간데이터 공유의 장애요인에 대하여 다르게 인식하고 있는 것으로 나타났으며 이러한 사회적 신념이 행동의도에 영향을 미쳐서 또 다른 비기술적 장애요인이 발생하였다. 본 연구는 공간데이터의 활용확대를 위하여 인간의 행동예측을 위한 계획행동이론의 적용 및 공간데이터의 흐름을 파악하기 위한 사회연결망분석을 실시하여 부서에 속한 담당자들의 인식 및 공유장애요인을 규명하고 데이터 활용 확대로 접근할 수 있는 윤곽을 제시하였다.

This study is to propose the ecosystem service valuation method as a complementary or alternative tool to overcome the limitations of the contingent valuation method(CVM), typically used to assess social benefits in preliminary feasibility studies. With an increasing interest in natural and environmental restoration projects, we assessed social benefits with theses CVM and ecosystem service valuation method from a case of Janghang wetland restoration project and compared the extent of the two social benefits. For quantitative evaluation of ecosystem services, the biophysical quantity for each ecosystem service indicator was calculated and then converted into currency (KRW) units to estimate the economic value of ecosystem services. The four ecosystem regulating service indicators were selected including greenhouse gas capture/storage, air pollution, water quantity and quality regulation. The amounts of CO₂ sequestration and storage as a ecosystem's greenhouse gas regulating service in the study area were 73.04 tCO₂/yr and 5,867.53 tCO₂/yr respectively. The reduction of SO₂, one of air pollutant gases by ecosystems was calculated to be 180.27 kg/yr, the reduction of NO₂ to be 378.90 kg/yr, and the reduction of fine dust (PM10) to be 9,713.92 kg/yr. The amount of freshwater regulating service by the ecosystem was estimated to be 459,394,319ℓ/yr, and the amount of nitrogen in freshwater removed by the ecosystem was 78.00kg/yr. Study results show that the benefits derived from the CVM were KRW 227.8 billion over the 30-year analysis period and those from the ecosystem service valuation method were KRW 41.4 billion for regulatory services and KRW 148.8 billion for cultural services, totaling KRW 189.5 billion. With KRW 184.8 billion of the total costs, the benefit/cost ratio using the CVM was 1.23 and that with the ecosystem service valuation method was 1.03. This study implications include that the CVM and ecosystem service valuation method can be applied together to assess and compare social benefits for natural and environmental restoration projects.

Purpose: The purpose of this study was to develop a resource-based relative value scale (RBRVS) and its conversion factor for advanced nursing practices carried out by critical care nurse practitioners (CCNP) in intensive care units. Methods: The methodology was developed by calculating CCNP's RBRVS for 32 advanced nursing services based on CCNP's workload and time spent in the context of national health insurance. A cost analysis was performed to estimate the conversion factor of CCNP's RBRVS. The share of CCNP's contribution to fee-for-service in intensive care units was also analyzed. Results: Calculation of the RBRVS of 32 advanced nursing practices showed a range of points from 100.0 to 1,181.4 and an average of 296.1 points. The relevant conversion factor for advanced nursing practices in CCNP were estimated at 37.3-48.4 won. The contribution rate of CCNP's advanced nursing practices in the relative value scale of the national health insurance was estimated at 0.1-31.3%. Conclusion: Measuring the economic value of advanced nursing services will be a basis for esta-blishing a reimbursement system for CCNP's practices and thus encourage a social demand for advanced nurse practitioners.

Objectives : To evaluate the predictive validity of three scoring systems; the acute physiology and chronic health evaluation(APACHE) III, simplified acute physiology score(SAPS) II, and mortality probability model(MPM) II systems in critically ill patients. Methods : A concurrent and retrospective study conducted by collecting data on consecutive patients admitted to the intensive care unit(ICU) including surgical, medical and coronary care unit between January 1, 2004, and March 31, 2004. Data were collected on 348 patients consecutively admitted to the ICU(aged 16 years or older, no transfer, ICU stay at least 8 hours). Three models were analyzed using logistic regression. Discrimination was assessed using receiver operating characteristic(ROC) curves, sensitivity, specificity, and correct classification rate. Calibration was assessed using the Lemeshow-Hosmer goodness of fit H-statistic. Results : For the APACHE III, SAPS II and MPM II systems, the area under the receiver operating characterist ic(ROC) curves were 0.981, 0.978, and 0.941 respectively. With a predicted risk of 0.5, the sensitivities for the APACHE III, SAPS II, and MPM II systems were 81.1, 79.2 and 71.7%, the specificities 98.3, 98.6, and 98.3%, and the correct classification rates 95.7, 95.7, and 94.3%, respectively. The SAPS II and APACHE III systems showed good calibrations(chi-squared H=2.5838 p=0.9577 for SAPS II, and chi-squared H=4.3761 p=0.8217 for APACHE III). Conclusions : The APACHE III and SAPS II systems have excellent powers of mortality prediction, and calibration, and can be useful tools for the quality assessment of intensive care units(ICUs).
