The variation of stream flow is the one of the most important factors which influence on that of water quality in the unit watershed. The target water quality goal is established and permissible load is allotted in the base of the standard flow condition along with its water quality for the management of Total Maximum Daily Loads (TMDLs). A standard flow selected could cause problems in the load allotment if it was not properly arranged. This study reviewed the acquisition of water quality data, the self-variation and the retainability in water quality on the specific flow conditions. This study also proposed the median and the adjusted average flow condition out of general flow conditions as alternative standard flow conditions. It is considered that the alternatives can make the water quality data easily acquired and the water quality representativeness more enhanced on the standard flow conditions.

비점오염원 관리를 위한 독립호우의 결정은 월류수 처리시설의 설계에서 필수적이다. 비점오염원의 관리를 위해서는 총량을 결정해야만 하는데 이를 위해서는 결정된 독립호우에 의해 1회 평균강우량, 평균강우강도, 평균지속시간 등의 강우특성의 분석이 실시되어야만 한다. 독립호우의 결정은 무강우 지속시간의 산정(Interevent Time Definition, IETD)에 따라 분리할 수 있으며 이를 결정하기 위한 기존의 분석방법에는 자기상관 분석, 변동계수 분석, 연강우 평균발생횟수 분석 등이 있다. 본 연구에서는 기존의 IETD 분석방법에 따라 무강우시간을 산정한 후 방법별 문제점을 고찰하고 새로운 IETD 결정방법으로 지수함수 검정방법을 제안하였다. 또한, 검정방법을 통하여 결과값의 적절성을 검토하였다.

The objectives of the study were to. 1) explain the seriousness of environmental problems and the importance of environmental education in rural development , and 2) explore more effective and efficient ways of environmental education for agriculture and rural development in Korea. The world has rapidly changed and concepts such as clientele -centered, efficiency, and globalization are flowing under this change. Agriculture or rural development is not an exception. In order for agriculture as an occupation and rural communities to have competitiveness in efficiency and attractiveness, it is important to develop and execute a well-planned program for agriculture and rural development. Otherwise, farmers and rural inhabitants will continue to leave the agriculture and rural areas. Frequent recent reports of newspapers on nit and water pollution, including nutrients and pesticides have brought attention to the seriousness of environmental problems in Korea. Environmental concerns should consider in planning and executing the rural development program. People want to get contamination-free foods, water and fresh air. They can and are willing to pay their money for high quality food, water and a better living environment, as their incomes have been increasing, Agriculture and rural communities may have competitiveness in these aspects. It is irony that environmental concerns makes the possibility of changes in agriculture and rural development in Korea. Environmental education will have an increasingly important role in agriculture and rural development. Environmental problems relate to the human behavior in various aspects. Many environmental problems are mainly rooted to people's ignorance and spending-habits, and lack of technology related to environment. These human behaviors are the focus that environmental education should teach and change. Environmental education has been carried out through various subjects in school education in Korea, but "Environment" in middle school and "Environmental Science" in high school were separated as a regular subject from 1996. Environmental education still has a lot of room for development from a theoretical frame work. Environmental education should be carried out as action-oriented, student-centered programs. Various teaching materials, programs and proper supporting budget should be developed so that environmental education fulfills its necessary role well in agriculture and rural development. A textbook about the environment alone will not guarantee a high quality environmental education.

Air pollution problems due to the emission of pollutants from the various industrial facilities become serious issues and lots of air pollution control processes have been developed. To remove the SO$_2$ and NOx emitted from the solid waste incinerator and coal fired power plants, we studied the Ca-based sorbent which was prepared by waste clam and limestone. The objectives of this study were to develop a clam-based sorbent for removal of SO$_2$ and NOx, and to investigate the physicochemical properties of the waste clam sorbent. In order to determine acid gas removal capacity of sorbent, the batch study on SO$_2$ and NOx removal was performed with the Ca-based sorbent in the fixed bed reactor. Results of the research revealed that clam-based sorbent can be used as the iron-manufacturing industry and chemical adsorbents for the removal of acid gases because the lime content of the waste calm was more than 53.92%. From physicochemical analysis and gas reaction experiments, it could be concluded that clam is good sorbent for the removal of SO$_2$ and NOx in waste incinerator and flue gas desulfurization processes.

The coastal waters and the adjacent coastal lands strongly influenced by each other and includes islands, transitional and intertidal ares, salt marshes wetlands and beaches. We focus on the coastal zone because of its unique geographical characteristics, Its ecological and economic importance, and the increasing pressures on its integrity. Our coastal zone have been controlled individually about 50 of a different kind of laws, as a result, to reach an individual purpose of the laws, people have developed the coastal zone without considering environmental condition, which brought about ecological destruction, pollution and devastation of the coastal areas. Finally, In 1999, the Coastal Management Act and the Wetlands Conservation Act were established and hereafter the environmental concern has been increased. They will be an important role to preserve our environment of coastal zone. Here I will examine the Laws concerned with environmental management of coastal zone and indicate immanent problems of it. So, I expect that problems will be improved one by one through this paper.

We live in an age of information. We also live in an era of rising environmental awareness. As a result, efficient and judicious use of environmental information has become a prerequisite to planning and management of environmental affairs in contemporary societies. During the past few decades, we have recorded a phenomenal rate of growth. and experienced an array of environmental problems such as pollution, destruction of natural environment, and ecological disturbances. In response to these problems we has embarked on a study of Environmental Information System(EIS). This study has four major components. First, it describes the current status of EIS in Korea. Second, it provides a survey of EIS in other countries, specifically USA and Japan. Third, the study also presents an application of GIS(Geographic Information System)in Korea, USA, and Japan. Finally, the study outlines strategies to develop EIS in Korea.

Objectives: The main purpose of this review is to introduce the current status of environmental health indicators of Korea and to share our experience of the developmental process of Korean version of environmental health indicators. Methods: This paper describes 1) the background of environmental health indicators; 2) the ways how we developed environmental health indicators of Korea; 3) the current status of selected indicators; and 4) suggestions for the further policy development. Results: The 6-year long project for the development of environmental health indicator systems in Korea could provide outputs on three major distinct aspects on the indicator issues. Firstly, we have developed the rational process/manual so that the government can select and advocate the potential indicators with a relatively objective manner. Secondly, we have suggested the potential candidate indicators which can be implemented immediately. We also pooled all indicators in order to evaluate the summary index which we expect to tell the status of environmental health. Third, we provided suggestions on the further utilization of this indicator system. Conclusion: The mission of environmental health policy is to resolve the public health problems occurring because of hazardous environment. In order to identify the environmental determinants of the community health problems and to evaluate the effectiveness of the policy implemented, these environmental indicators can be used. Therefore, the government should implement this ready-prepared system of environmental health indicators.

Recently, it is recognized as a high-cost and inefficient logistics system that increases traffic congestion and environmental problems due to an increase in traffic volume due to the activation of the online market. In order to solve inefficient problems such as unavoidable traffic congestion and environmental problems caused by the increase in traffic volume, it is necessary to develop a freight transport system technology using the existing urban railway infrastructure and freight-only urban railway. The urban subway logistics system is a logistics system that requires a combination of various technologies to solve the nationwide demand for urban logistics and road traffic problems. This paper recognized the existing traffic congestion and environmental pollution of road traffic as problems, and supplemented the contact point requirements presented above by identifying the sub-systems constituting the target system and supplementary points for each part-level contact point. In this study, as a complex system operated for one purpose by grafting various technologies, a plan is required to secure the reliability and safety of operation from various viewpoints. The results of this study can contribute to the initial configuration and basic data to solve the interface bottleneck of the urban subway logistics system to be promoted in the future.
