Through case studies of photovoltaic complex and wind farm construction and management, the causes of environmental and social conflicts were analyzed. Policies and measures to minimize conflicts and complement the institution were identified by analyzing successful construction and management case studies from both domestic and abroad. The causes of problems were haphazard damages to the regional environment, direct damages from power production facilities, lack of regional benefits from power production businesses, and loose environmental restrictions and management. The countermeasures to mitigate the problems at hand are to improve and strengthen the guidelines for power production businesses, secure residents' acceptability, strengthen regulations for business explanation, increase stakeholder's participation, find alternative sites, and ensure the speedy implementation of on-shore wind farms. Through these countermeasures, specific goals included in the New Renewable Energy Master Plan, such as target goals for photovoltaic and wind energy, preservation and protection of environment, and improvement of residents' acceptability, can be achieved.

In this work, a new adaptive weighted mean filter is proposed for preserving image details while effectively suppressing impulse noise. The proposed filter is based on a noise pixel detection-estimation strategy. All the pixels are first detected using an impulse noise detector. Then the detected noise pixels are replaced with the output of the weighted mean filter over adaptive working window according to the rate of corrupted neighborhood pixels, while noise-free pixels are left unaltered. We compare the proposed filter to other existing filters in the qualitative measure and quantitative measures such as PSNR and MAE as well as computation time to verify the capability of the proposed filter. Extensive simulations show that the proposed filter performs better than other filters in impulse noise suppression and detail preservation without increasing of running time.

It is, as everyone knows, very important for human beings to protect and conserve marine environment. We has believed the ocean is so wide and deep that it cannot be polluted. But it has begun to doubt the capacity of self-purification of the ocean due to pollution arising from marine casualities. It has proved that semi-enclosed sea is likely to be polluted and cannot be restored easily once pollution occurs. Therefore, first of all it is important to take preventive measures for prevention of marine pollution in the semi-enclosed sea like the Yellow Sea. Many of regional conventions for prevention of marine pollution have come into existence. this dissertation was set out for the fact that the Yellow Sea is semi-enclosed sea which is vulnerable to marine pollution. It is desirable not to deal with marine preservation of the Yellow Sea by a single exclusively but to deal with it by cooperation of all coastal states under the present circumstances. I proposed a program of regional cooperation to protect and conserve the Yellow Sea. This program must be progressed with gradual arrangements. First, they must establist a basic cooperation committee to work basic affairs on the protection of marine environment within the Yellow Sea. The Committee Mainly play parts of study and research concerned with pollution of the Yellow Sea in the non-governmental side and consist of legal and scientific experts. Second, they must establish the control Committee to prevent marine pollution of the Yellow Sea substantially. There is a reason that regional cooperation cannot be directly concluded with the regional tready. Because there is a problem of Recognition of States left. In principle, a subject of tready must be a state in the International Law. But they have not made Recognition of State which is demanded by International Law between North and South Koreas. Therefore, the Control committee must play a substantial part of prevention from pollution instead of the treaty. Finally, we concluded tentatively named $\ulcorner$Convention on Regional Cooperation for Protection of Marine Environment of the Yellow Sea from Pollution$\lrcorner$ if the matter is settled which is related to Recognition of States in the International Law.

As records managers are assigned in accordance with act on public records management, the record management has settled down a bit, and also much effort is put to perform the record management in accordance with law. The record management includes all the works like production, classification, organization, transfer, collection, evaluation, disuse, preservation, opening to the public and application. Among them, the record transfer is an important work that performs the initial stage in which the main agent of management is changed from administration department to record center. Thus this study suggested the improvement measures for non-electronic record transfer after examining the current transfer state of 16 local governments in Busan region and also problems occurring in the process of transfer through interviews with institutional records managers.

The total mercury concentration ($Hg_T$) of surface snow samples collected along a ~1500 km transect in east Queen Maud Land was determined using inductively coupled plasma sector field mass spectrometry to address the behavior of Hg on the Antarctic Plateau. Due to the volatile nature of mercury, measures were taken against Hg loss from standard solutions by choosing appropriate container material and stabilizing agents. Glass bottles with Teflon-lined caps were superior to Teflon and polyethylene containers in protecting against Hg loss, but addition of gold chloride ($AuCl_3$) or bromine chloride (BrCl) was necessary to ensure preservation of Hg. As Hg loss was also observed in snowmelt samples, our analysis may underestimate the actual amount of HgT in the snow. Even so, the measured HgT was still very low (< 0.4-10.8 pg $g^{-1}$, n = 44) without a signal of depositional enhancement accompanying photo-oxidation of atmospheric elemental mercury in austral midsummer. Moreover, the dynamic variation along the traverse implies spatial and temporal heterogeneity in its source processes.

Among the rivers in Korea, the Han River is the largest, most important one, which runs through the Seoul metropolitan region in the west toward the yellow sea. In the Han River basin there live as many as 17.1 mil. people including appr, 11 mil, citizens in Seoul. The Seoul Metropolitan region, already containing appr. 40% of the nation's total populating, expectedly poses an ever-growing polluting burden to the Han River. Due to Korea's vigorous industrialization and heavy urbanization in the past quarter century, water pollution was observed to be increasing in the Han River until the mid-1980's, but thereafter the Han River began to improve little by little by virtue of the government's massive investment and all-out efforts in water preservation. Public awareness on the importance of environmental protection is increasing unprecedentedly. With a view to meeting people's growing demand for clean water and pleasant environment, the government established the "Comprehensive Mid-Term Environmental Conservation Plan" (1992∼1993) in 1991. According to the plan, 1,315 bil.won(1.7 bil.us$ ) is to be poured into the Han River Basin to install 113 water pollutant abatement plants including 43 treatment facilities. To successfully cope with the future's challenging need for the environmentally sound sustainable development, a variety of measures and an array of policies are going to be incorporated with emphasis on, -redistributing such polluting sources as population and industries -tightening control of the water pollutant discharge -restricting the pollution-accompanying land use -enhancing the assimilation capacity of the river -stirring up the public awareness and participation in the environment protection We hopefully anticipate that with those e(forts the Han River will improve as drawn in the attached "1996's Envisioned Han River Quality".

Under Korea's Enforcement Decree of the Framework Act on Environmental Policy amended in 2013, total organic carbon (TOC) is newly added as water quality parameter to assess organic pollution in water and aquatic ecosystem. To meet the TOC requirement and improve quality of effluent discharged into public watershed, it is also necessary to develop standards for TOC in effluent from public sewage treatment works (PSTWs). In this study, we reviewed the characteristics and removal efficiency of TOC in influent and effluent of PSTWs. The study found that phosphorus treatment process removed not only soluble phosphorus but also a portion of TOC remaining after the secondary treatment process. TOC concentration in effluent from PSTWs operated in tandem with industrial wastewater treatment work was higher due to influx of insoluble substances from the industrial wastewater treatment work. In order to lay a foundation for the management of TOC from PSTWs, it is necessary to carry out research on TOC from different perspectives. For example, studies on the generation mechanism of TOC and the impact of TOC on drinking water resources, assessment of effluent qualities through monitoring, and development of measures to control TOC for the preservation of aquatic ecosystem are needed.

The ‘Ecosystem St Environment’ subject is included in the 7th revised curriculum for high schools in Korea, which ‘Environmental Science’ subject in the 6th curriculum was changed to. The 6th curriculum was announced in 1992 and has been applied till now, and the 7th revised curriculum was announced in the late of 1997 and will start to be applied in school education from 2001. The ‘Ecosystem & Environment’ subject is an integrated subject for liberal arts and science, which deals with environmental problems with approaches of natural science and social science. Its significance lies in understanding and solving environmental problems, and thus improving the quality of human life. And it is aimed to achieve the goal of environmental education in connection with ‘Environment’ subject in middle schools, which is one of the three optional subjects. This subject consists of six domains: human being and environment, ecosystem and environment, environmental pollution, global environmental problems ＆ their measures, environment and society, and environmental preservation. Compared with ‘Environmental Science’ in the 6th curriculum, in this subject less emphasis is put on environmental technological approach and more emphasis is put on environmental ethics and environmental social approach. On the contrary, one unsatisfactory point is as the following: locally integrated solutions of environmental problems are omitted: the organization of the textbook is more or less sporadical and sometimes overlapping; practical solutions are not concrete in writing the textbook and teaching it. The ‘Ecosystem & Environment’ subject which has been organized with new contents according to the 7th revised curriculum for high schools will be successful in achieving the given goal only when a lot of high schools select this subject and are taught effectively.
