This study sought to find a nursing intervention tool for enhancing elderly women's lives by investigating the causes and the meaning of their grief. Method: This research was derived from a phenomenological tool such as qualitative research design. The data collection took place from December of 2000 until April of 2001 Through systematic interviews and participatory observations of five elderly women attending C welfare center located in downtown Seoul the data was collected. Each interview lasted an hour and a half and was arranged five times. The analysis of this research was conducted using the Giorgi method. Results: \circled1 There was obvious physical and physiological decline caused by aging old; as well as there being spouse health problems, additional physical suffering, signs of senility, and insomnia, \circled2 Further grief was imposed by unpleasant memories of the spouse; infidelity, incapability, and even disregard of her own well-being, \circled3 Then there was pity for children; unfaithful children, uncertain futures of the children, and early death of a child, \circled4 Also, regrettable fate, painful daily acttrities, unreliable factors, bad circumstances, and feelings emptiness were reported, \circled5 Finally, anxiety for the future; ac sense of despair, loneliness, economic hardship, and the fear of imminent death increased grief levels. Conclusion: A variety of programs and social meetings for the elderly to overcome their physiological or psychological crisis should be substantially developed and supported by the government. In order to implement the social welfare for the elderly women, special consideration whether on the governmental level or the personal level, should be devoted to the elderly who live without any financial support or social concern.

The purpose of this study is to analyze the usage of eco-friendly elements in Korean traditional architecture to evaluate Hanok(Unjoru and Jinwondang) according to Green Building Certification Criteria(G-SEED). The results of this study were as follows; Unjoru and Jinwondang was not enough to obtain certification points. From Site usage and Traffic category, Jinwondang gets more points than Unjoru. It's because Jinwondang is located in downtown Seoul, so it gets more points of traffic and neighborhood facility. From Energy and Environmental Pollution category, Jinwondang gets more points of energy performance than Unjoru, too. It's because Jinwondang secured insulation performance of wall and windows using insulator and glass. From Resources category, Unjoru gets more points than Jinwondang. It shows that modern Hanok was limited using natural resources. From Ecological Environments category, Jinwondang is located urban area, it's difficult to secure the open space, so Unjoru gets more points than Jinwondang. If Modern Honok installs a system that can getting point and secure insulation performance, it will be certificated according to G-SEED.

As the power demand has increased and power industry deregulation has progressed, the transmission and distribution system will have more complicated problems by the influence of investment reduction and NIMBY phenomena for overall power system. It is expected that the route length per MW demand will reduce gradually from 0.6[C-km/MW] to 0.53 [C-km/MW] in 2010. This comes up to a real serious problem of system planning and operational viewpoints. HTS technologies related to power system have properties to solve these complex transmission and distribution constraints, especially for metropolitan area, in the future. As the HTS technology has developed, the HTS cable technology can be the most effective alternative to solve the future expected power network constraints. This paper describes the application methodology of developing 22.9㎸ HTS cable by CAST for practical distribution system. 22.9㎸ HTS cable under development with step-by-step application methodology can substitute the existing and planning conventional 154㎸ cable. If this scheme is applied, part of downtown 154㎸ substation of metropolitan city such as Seoul can be changed into 22.9㎸ switching station. It can give great economic, environmental and additional benefits to all of the concerned authorities.

This paper presented neural network modeling method using vehicle data to predict fuel consumption. To acquire data for training and testing the proposed neural network, medium-class gasoline vehicle drove at downtown and parameters measured include speed, engine rpm, throttle position sensor (TPS), and mass air flow (MAF) as input data, and fuel consumption as target data from OBD-II port. Multi layer perception network was used for nonlinear mapping between the input and the output data. It was observed that the neural network model can predict the vehicle quite well with mean squared error was $1.306{\times}10^{-6}$ for the fuel consumption.

As the power demand has increased, it is expected that the transmission system will have more complicated problems under the influence of investment reduction for overall power system. The route length per MW demand will be reduced gradually from 0.6［C-km/㎿］ to 0.53 ［C-km/㎿］ in 2010. This comes up to a real serious problem of system planning and operation viewpoints HTS power technologies have properties to solve these complex transmission and distribution constraints, especially for metropolitan area, in the future. As the HTS technology has developed, the HTS cable technology can be the most effective alternative to solve the future expected transmission constraints as compared with other countermeasures in terms of economics, environments and system operation. This paper describes the general application methodology of developing 22.9 ㎸ HTS cable by CAST for practical distribution system, particularly, step-by-step application methodology of 22.9 ㎸ HTS cable to substitute the existing and planning 154 ㎸ cable. In this scheme, almost of the downtown 154 ㎸ substation of metropolitan city such as Seoul will be changed into 22,9 ㎸ switching station.

Many Korean palaces such as Deoksu Palace and Kyungbok Palace are located in downtown Seoul. Modern high-rise buildings around the palace have been the background scenery of traditional architecture in it. In this case, such landscapes mixed with traditional images and contemporary images can give a negative impression to visitors watching from inside the palace. In this study, we analysed the correlation between landscape image of Deoksu Palace and trees' view blockage of buildings around it with three independent variables. The first variable is completely blocked view of buildings around the palace by the trees. The second variable is half-blocked view of buildings around the palace by the trees. The third variable is the view of buildings around the palace that is not blocked by the trees. The analysis showed that there were some significant correlations between landscape image of Deoksu Palace and trees' view blockage of buildings around it. It also showed that the view blockage ratio by the trees has positive correlation with improvement of landscape image of the palace.

Today, the availabity of usable pieces of land in urbanized areas is very limited. Specifically, it is very difficult to secure a piece of land to be used as a park for the public, mainly due to the high price of land in cities. However, the City of Seoul has carried out three action plans to secure land deemed for insufficient parks and to vitalize these small piece of land in downtown areas such as following: 1. Ssamzie-park(Korean version of a 'vest pocket park') Development Plan in 1990 through 1991. 2. Modernization Plan for Children's Parks since 1994. 3. Maeul-madang (Korean version of 'community garden')Development Plan since 1996. The purpose of this study was to present some design approaches for practical use of small urban spaces by articulating the concepts of Modernization Plan for Children's Park and Maeul-madang Development Plan of the winning entries and by describing how the concepts were actualized in reality.

Recently one of interest concern in domestic housing market is to reduce the difference of supply and demand. Exact demand estimation by accurate demand region is a essential cue to reduce the gap. This empirical study compared the data of housing subscriber's real address with estimated demand area on household movement, which are applied by advanced studies. This empirical case data is related to 3 housing development districts in metropolitan area. As a result, This study found that the real demand area has a more widened coverage compared with those of household movement one. For to establish exact demand area, we found, more complementary considerations should be taken. Especially some factors such as distance between a project site and downtown of Seoul Metropolitan City, locational competitiveness on main demand and behind demand, and development scale are more considerable variables. In additionally, we found the demand areas are influenced by housing rental types, sizes and the real estate business trends. And also, this study found those factors should be considered with housing price and locational competitiveness.
