  • BACKGROUND: In this review paper, the effects of surface cover (SCV), vegetative filter strip (VFS), and vegetated ridge (VRD) on the pollutant runoff from steep-sloping uplands were analyzed to compare the pollutant reduction efficiency in runoff ($PRE_{runoff}$) of the practices and to investigate how slope and rainfall parameters affect the $PRE_{runoff}$. METHODS AND RESULTS: The $PRE_{runoff}$ of SCV, VFS, and VRD for pollutants including suspended solids and biological oxygen demand was compared by analysis of variance. The effect of slope and rainfall parameters on the $PRE_{runoff}$ was explored by either mean comparison or regression analysis. It was found that the $PRE_{runoff}$ differs with the practices due to different pollutant reduction mechanisms of the practices. Though the $PRE_{runoff}$ was likely to be affected by site condition such as slope and rainfall (amount and intensity), more comprehensive understanding was not possible due to the limited data set. CONCLUSION: The $PRE_{runoff}$ of SCV, VFS, and VRD differed due to the distinctive mechanisms of pollutant removal of the practices. It is necessary to accumulate experimental data across a variety of gradient of slope and rainfall for comprehensive understanding of the effects of the practices on pollutant runoff from steep-sloping uplands.

  • Purpose: The purpose of the study is to determine the level of environmental governance practices of Local Government Units (LGUs) on the implementation of waste policies. It determines the level of compliance with the waste policies implemented by LGUs particularly on waste resource conservation and waste reduction; the degree of the implementation of the environmental governance on education, values, health, and economic sufficiency. Also, it determines the initiatives done by the local government units to decentralize the leadership on waste sustainability. Research Methodology: The survey method was employed to gather information from municipalities and cities on waste programs implemented by the local government units. The data were gathered from households, schools, businesses and industries; and local government units. Results and Conclusions: The findings revealed that the level of environmental governance on waste reduction and waste resource conservation was fairly implemented by the local government units. The LGUs used the four areas of governance to keep the municipality self-sufficient, well-managed, and free from waste issues. The research can be used by the academe as a good teaching material for social responsibility, public administration, strategic management, and environmental-related courses.

  • Health could be maintained and promoted by pursuing an active healthy lifestyle. Life-style include health habits and behavior pattern such as exercise, diatry change, weight control, stress management et al. The objectives of this studies are (1) to analyze recognition and practice of lifestyle between nurses and non-nurses, (2) to analyze health status of clients which presented healthy lifestyle, (3) to analyze factors that affected healthy lifestyle. The lifestyle assessment questionnaire is divided into ten sections: competence in selfcare, nutritional practices, physical activity, sleep patterns, stress management, self-actualization, sense of purpose, relation with others, environmental control, and use of health care system. The major results are as follows : (1) The level of recognition and practice of lifestyle was not high. Nurses showed more higher score than non nurses in lifestyle area such as competence in selfcare, stress management, environmental control, and use of health care system. (2) Good health status and lifestyle presented positive relation. (3) In mutiple classifiction analysis, competence in selfcare, nutritional practices, physical activity, sleep patterns, stress management, environmental control, and use of health care system had significant relation to independent variables. (4) Change of concept for healthy lifestyle after this survey was higher in nurses group and the most concern area was stress management. To sum up, lifestyle pattern of nurses as health professional was not desirably high. Therefore nurses ownself should effort to practice healthy lifestyle prior to others, and then educate importance of lifestyle for health promotion and disease prevention. In conclusion, it will be useful to consider significant lifestyle factors that was be identified in this study to develop health promotion program.

  • BACKGROUND: It is essential to prioritize the exact and clear understanding of agricultural nonpoint source pollution (NPS) controls. The realistic policies and systems should also be developed based on this understanding. Therefore, this study aimed to present agricultural Best Management Practices (BMPs) applicable for the fields based on the Delphi survey result. METHODS AND RESULTS: This study deduced the evaluation items to assess each BMP for agricultural NPS control and conducted the surveying using the Delphi method based on agricultural BMP experts. In addition, its on-the-spot application were evaluated. Considering its importance, technical, social and economic proprieties showed that political support was ranked first and followed by cost investment, labor investment, reduction effect and resident participation. The survey findings by agricultural BMP experts showed the good performance of on-the-spot application can be achieved from fertilization by soil testing, residue and green manure application and contour plowing which are applicable within a field. Agricultural BMPs, highly applicable for the fields, were the countermeasures that farmers who are the principal bodies of agricultural NPS control could be participated directly. CONCLUSION: The active participation of farmers is essential for effective control of agricultural NPS. It is necessary to establish various incentive systems.

  • Load Management, is originated from efficiency improvement of energy use, or energy conservaion. Traditionally, electric utilities have constructed new power plants to meet the steadily increasing electricity demand. Power development planning, however, is becoming more difficult in the countries like Korea, Japan, and the United States, and increasing concerns about global environmental problems necessitate changes from existing supply-side options based on fossil-fuel to environmentally agreeable supply strategies. This paper discusses the demand side management strategy with emphasis on the concept, implementation scheme, and current practices employed in utilities.

  • 우리나라에서는 유역 특성별 비점오염물질 유출특성을 파악하고 최적관리방안을 도모하기 위해 2000년 이후 다양한 형태의 실험실 규모 또는 실증 규모 최적관리방안(Best Management Practices, BMP) 시설에 대해 연구가 진행되고 있으나 유역 특성상 자정작용의 기회가 주어지지 않는 연안지역에서의 비점오염물질 유출특성 및 관리방안에 대한 연구는 미비한 상태이다. 최근 연안지역 개발에 따른 불투수층 비율은 지속적으로 증가하고 있으나, 초기우수의 직접유출을 방지하기 위한 완충 시설 및 최적관리방안 시설은 전무한 상태이다. 본 논문에서는 충남 보령시 대천항 주차장을 중심으로 연안 지역의 비점오염물질 유출특성을 파악하고, 이를 저감하기 위한 최적관리방안을 설정하여 연안지역 비점오염원 관리에 대한 기초자료를 제공하였다. 연안지역은 지역특성상 해안과 접하고 있기 때문에 지하수위가 낮고 경사차가 크지 않은 평탄한 지형을 이루고 있다. 즉, 최적관리방안을 선정하는데 있어 유출입구의 수두확보문제와 굴착 깊이에 제한을 받으며, 인공습지 및 저류지와 같은 대규모 저류형 시설의 입지조건으로는 부적합하다. 또한, 연안지역은 강우유출 특성상 염분의 함량이 높기 때문에 식물 생장에 미치는 영향이 커 식생을 이용한 자연형 최적관리방안 시설을 적용하는데도 제약을 받는다. 연안지역 비점오염원 유출 특성과 연안지역 지리 지형적 조건을 고려하여 선정된 최적관리방안 시설의 주관평가 결과 시공시 굴착 깊이가 적고, 식생의 이용이 제한적인 침투수로 형태의 시설이 적합한 것으로 사료되며 유지관리 측면에서도 유리하다.

  • 본 연구에서는 동적생장모델을 이용하여 산림경영(간벌작업)의 수행여부에 따른 산림의 재적변화량, 산림의 바이오매스와 탄소흡수량을 추정하였다. 간벌 수행 여부에 따른 산림의 재적 변화량을 추정한 결과, 간벌을 수행하였을 경우의 산림 재적 변화량이 현저히 높게 추정되었으며, 이로 인한 산림의 탄소흡수량의 차이도 매우 크게 추정되었다. 간벌이 이루어지지 않은 산림에서의 탄소흡수량은 0.27tC(탄소톤)/ha로 추정되었으며, 간벌이 이루어진 산림에서는 166.02tC(탄소톤)/ha(상층간벌), 163.75tC(탄소톤)/ha(하층간벌)로 각각 추정되었다. 따라서 간벌은 산림의 탄소흡수량 증진에 매우 큰 영향을 미치는 것으로 판명되었으며, 각 간벌유형별 탄소흡수량은 큰 차이를 나타내지 않았다. 따라서 산림의 탄소흡수 및 탄소흡수량 증진을 위해서는 간벌작업을 통한 산림경영이 필수적인 요소라고 판단된다.

  • Despite the most severe weather and geological conditions, Korean people in earlier times were successful in maintaining sustainable water supplies because they understood the importance of rainwater management, and developed technologies and a philosophy which were needed to live under such circumstances. Recently, the Korean people have suffered frequent incidence of flood damage and drought, and have gradually started to remind themselves of the lessons of the past, which can be described as proactive, multipurpose rainwater management. Most of the problems associated with water and energy can be solved by the integration of rainwater management practices. The concept of multipurpose rainwater management and two examples of its practice are discussed. One is a design for a multipurpose rainwater tank which has been used in a building project, and is based on Korean philosophy. Secondly, a regulation was promulgated recently in Seoul that requires the building of rainwater tanks in new buildings over a certain size. The primary purpose is for the prevention of flooding, but water conservation is a secondary intention. Two examples of proactive rainwater management are discussed, one being public involvement in rainwater management, and the second being the rainwater piggy bank microcredit project. In order to maintain sustainability, to meet the requirements of the Millennium Development Goals, and to be prepared for the effects of climate change, it is expected that multipurpose and proactive rainwater management will be a very effective approach for both developing countries and developed countries. A worldwide network of scientific researchers, as well as a great number of professions, has suggested the promotion of rainwater management.
