Understanding the thermohydraulic processes in the aquifer is necessary for a proper design of the aquifer thermal energy utilization system under given conditions. Experimental and numerical test were accomplished to evaluate the relationship between the geothermal heat exchanger operation and hydrogeological conditions in the open-loop geothermal system. Sand tank experiments were designed to investigate the open-loop geothermal system. Water injection and extract ion system as open-loop borehole heat exchanger was applied to observe the temperature changes in time at injection well, extraction well and ambient groundwater. The thermohydraulic transfer for heat storage was simulated using FEFLOW for two cases of extraction and injection phase operation in sand tank model. As one case, the movement of the thermal plume was simulated with variable locations of injection and extraction well. As another case, the simulation was performed with fixed location of injection and extraction well. The simulation and experimental results showed that the temperature distribution depends highly on the injected water temperature and the length of injection time and the groundwater flow and pumping rate sensitively affect the heat transfer.

Because of the demographic and economic changes and the lifestyle diversification, the new housing types such as the Quasi-housing and urban small-size multi-unit housing are appeared in korea. The current housing use classifications are regulated in accordance with the housing divided ownership, horizontal and vertical size of housing, and the number of units. However, there is a limit to accommodate the new housing type. Therefore, this study proposed the direction of improvement of the housing use classifications through comparative analysis of foreign housing use classifications. Also, building regulations are applied according to the building use classifications. Therefore, the new housing types in building act are very urgent and important. So this study is derived the problems of the current housing use classifications and is proposed the improvement direction of it through the expert opinion survey.

The objective of this research is to provide the basic material for effective hospice care by analyzing the recognition of families who have terminally ill patients over death. To do so, this research is designed to investigate the general tendency toward death and changes after hospice care. To analyse the initial status of the recognition about the death, questionnaires were provided to the families of the terminally ill patients who were taken hospice care from June 1st, 2005 to September 10th, 2005 at Saemmul Hospice. The same questionnaires were distributed to research some changes of the recognition of the death after 3 weeks. As the Data Analysis Methodology, SPSS v.10.0 statistics program were utilized. The summary of this research is as follows. First, by gender, it is analyzed that women have more fear than men in terms of incompetence sense after death. By religion, Christians have less fear than other religious people in terms of fear toward after death and general sense of death. Second, those who experienced deaths of close family members, relatives, friends for the past 3 years have more fear toward the moment of death than those who did not experience it. Third, statistically valid difference was found in terms of fear toward the moment of death, fear toward incompetence, fear toward after death, and fear toward death before and after the hospice care was taken. Based on the result of this research, terminally ill patients' families facing death have shown significant differences on fear and incompetence before and after hospice care was offered. It is necessary that the hospice care should be settled more professionally by expanding the opportunities of hospice care and institutionalizing the system. In addition, hospice activities which are focused on providing hope after death and facing death with dignity and peace should be expanded increasingly as the family members who experienced deaths showed higher degree of fear and powerlessness and Christians have less fear toward death with the help of biblical influence. It is also required that hospice care specialized in recognizing the importance of terminal cancer patients and their families at the same time.
