The Doam lake watershed was designated as a non-point pollution management area in 2007 to improve water quality based on watershed management implementation. There have been studies of non-point source reduction with respect to the watershed management impacting the pollutant transport of the reservoir. However, a little attention has been focused on the impact of water quality improvement by the management of the dam operation or the guidelines on the dam operation. In this study, the impact of in-lake management practices combined with watershed management is analyzed, and the appropriate guidelines on the operation of the dam are suggested. The integrated modeling system by coupling with the watershed model (HSPF) and reservoir water quality model (CE-QUAL-W2) was applied for analyzing the impact of water quality management practices. A scenario implemented with sedimentation basin and suspended matter barrier showed decrease in SS concentration up to 4.6%. The SS concentration increased in the scenarios adjusting withdrawal location from EL.673 m to the upper direction(EL.683 m and EL.688 m). The water quality was comparably high when the scenario implemented all in-lake practices with water intake at EL.673 m. However, there was improvement in water quality when the height of the water intake was moved to EL.688 m during the summer by preventing sediments inflow after the rainfall. Therefore, to manage water quality of the Doam lake, it is essential to control the water quality by modulating the height of water intake through consistent turbidity monitoring during rainfall.

Objective : The purpose of this study was to comparatively analyze time use and quality of life in stroke patients who use Local community or convalescent Hospital environment. Methods : The study subjects were 74 stroke patients who were admitted to convalescent Hospital or who were being rehabilitated as outpatients. The Occupational Questionnaire(OQ)was used for measuring time use and the Stroke Specific Quality of Life(SS-QOL) utilized to measure Quality of life. Excluding 8 patients who did not fit selection criteria, 66 patients were selected and analyzed. Results : After comparatively analyzing time use in Local community and convalescent Hospital environment, significant differences were found in daily living(p<.05), resting(p<.05). In addition, in quality of life, significant differences were found in family(p<.05), self-management(p<.05), and social roles(p<.05). Conclusion : Local community patients used their time in daily living, resting more efficiently than convalescent Hospital patients, and also had a higher quality of life.

It has been known that torrential rainfall events have been occurring worldwide due to climate change. The accelerated soil erosion has caused negative impacts on water quality and ecosystem of receiving waterbodies. Since soil security issues have been arising in various areas of the world, intensive interests have been given to topsoil management in Korea. Thus in this study, Web GIS-based computing system of physical, chemical, and biological topsoil quality indices were developed. In this study, five soil quality maps at national scale and top soil erosion potential were prepared for evaluation of soil quality based on soil erosion potential. For this system, the open source Web GIS engine, OpenGeo, was used as core engine of the system. With this system, decision makers or related personnel in areas of soil erosion Best Management Practices (BMPs) would be able to find the most appropriate soil erosion BMPs based on soil erosion potential and soil quality at the area of interest. The Web GIS system would be efficiently used in decision making processes because of ease-of-use interface and scientific data used in this system. This Web GIS system would be efficiently used because this system could provide scientific knowledge to decision makers or stakeholders. Currently various BMP database are being built to be used as a decision support system in topsoil management and topsoil quality areas.

There are fifteen non-point pollution management areas in Korea and three of them (Doam lake, Daegi district and Golji-cheon) are located in the upstream of the Namhan river watershed. Many efforts to reduce non-point sources (NPS) pollution have been conducted, however, water quality pollution in the watershed is still serious. To solve these problems, it is a priority to grasp water quality using statistical techniques. In this study, a trend analysis was conducted to evaluate the effect of NPS management in the watershed. The long-term trends from 1996 to 2018 of water quality properties were analyzed using data collected from the water environment information system. Seventeen monitoring stations were selected along the main stream in Namhan river basin. Monthly water quality properties (BOD, COD, TN, TP, TN/TP ratio, Conductivity, SS and Chlorophyll-a) were collected and analyzed by Mann-Kendall test and LOWESS. The results showed that the Conductivity tended to increase in all regions and was the highest level in Jijangcheon. Organic pollution such as BOD and COD tended to increase in the Jungseon area. SS did not show a large tendency, but it showed high concentration in the Doam watershed. In all regions, 40% of water quality properties showed a tendency to 'UP', 15% of water quality properties tended to 'DOWN', and 46% indicated no tendency. In order to determine the cause of this, additional research and measures for improvement are necessary. This study will be used for the establishment of water quality policy in the future.

Purpose: The main purpose of this paper is to assess a body of research evidence that articulates the impact of physical and environmental factors on behavioral·psychological health and quality of life for the elderly people with dementia who reside in long-term care facilities. This follow-up study of the previous literature review aims to further identify physical and environmental factors, that improve health and quality of life for the elderly people with dementia, published in recent five years and to expand the understanding of clinical outcomes as mechanism that mediate the effect of physical environmental factors on improving behavioral·psychological health and quality of life for the elderly people with dementia. Methods: Comprehensive literature review has been conducted to identify empirical studies that link the design of dementia care facilities to health- and quality of care(QOL)-related outcomes and this follow-up review scrutinized peer-reviewed articles published in recent five years (from January 2018 to December 2022), filling the gap between the previous literature review and the current state of research. Results: The review identified a growing body of literature that articulates environment-related factors that improve behavioral·psychological health and quality of life for the elderly people with dementia living long-term care facilities. Implications: The findings of the review can be translated to design implications and design decisions to promote psychological and behavioral health and quality of life of people with dementia in long-term care facilities.

Purpose: This study is to propose direction for healing environment design in hospital architecture considering the characteristics of elderly patients. The primary goal of a public hospital is providing cheap health care and quality service chance to the underprivileged and elderly in the dead zone. Compared to the rapid increase of the aged population and chronic diseases, Ministry of Health & Welfare is currently planning model of health promotion hospital in development plans of local based public hospital. Due to the increased elderly medical expenses, elderly patients' high utilization is considered. Methods: The literature on the design factors of healing environments were investigated. based on this, analyzed drawings of surveyed hospitals ward in architectural characteristics and observe and evaluate directly healing environment design through field surveys. Results: The design of hospital environment affects patient's therapeutic effect. There is no any official formula for hospital design but environment that architect create could be a big part of the healing process. To increase the quality of the environment, apply the characteristic factors and harmonize well as a human-centered healing environment. Implications: Healing environment design for the elderly is first necessary condition due to high proportion of elderly patients.
