This thesis purports to overview the diverse administrative and organizational factors and plannings developed by the government organizations, municipal or otherwise, to tackle the Han River water pollution issues in the past years. This thesis also looks into the ever-worsening Han River water pollution problems, in particular, in terms of the various government plans ostensibly designed to reduce the pollution level but with little success. Also dealt with are the efficiencies with which the laws and decrees on water pollution the administrative organizations put to use in the prosecution of the diverse antiwater pollution projects involving the Han River basin. From the early 1960's up to the 1970's the government had concentrated on the growth-oriented economic policy with the result that little attention had been paid to the water pollution and other environmental issues that are bound to arise from the massive economic growth. Belatedly, the five-year Hah River Development Project was initiated in 1982 with emphasis on reducing the water pollution level at Hah River to the minimum. The following are the gists of the thesis and recommendations for the future antiwater pollution plans by the administrative organizations: 1. Documents to date indicate that the irrigation projects along the Han River area had been the main focus of attention during the Yi Dynasty and under the Japanese rule of the country. 2. Despite that the water pollution issue became the subject of many debates among the academic and research institutions in the 1960's and in the 1970's, the administrative organizations in charge of the Han River water quality control failed to come up with a concrete plan for the river's water quality control. 3. Nevertheless, the water pollution of the Han River area in fact began in the 1950's, with the unprecedented concentration into Seoul of population and the industrial facilities on a larger scale, in particular, enforced by the government's strong growthoriented policy in its Economic Development plans in the 1960's. 4. Starting in the 1960's, the Han River water pollution level dramatically increased, but the government was reluctant to promulgate or put into effect strong measures to curb the many factors contributing to the river water pollution, thus worsening the environmental issues along the Han River basin. 5. The environmental protection law and other laws and decrees relating to the antiwater and air pollution issues that were subsequently put into effect underwent so many changes that efficient anti-water pollution policies could not be effected for the Han River basin. The frequent organizational reshuffle within the administrative units concerned with environmental problems has resulted in the undue waste in personnel management and finance. 6. The administration on the environmental protection could not be efficiently carried out due to the organizational overlapping. Under the existing law, frequent organizational frictions and inefficiency are bound to occur among the central government offices themselves, as well as between the central government and the Seoul city administration, and among the city's administrative offices over the conservation of the Han River basin and over the river's anti-water pollution issue. 7. In the planning and prosecution of the Han River project, political influences from the president down to the lower-level politicious appear to have been involved. These political influences in the past had certainly had negative influence on the project, nevertheless, it appears that in the recent years, these political influences are not all that negative in view of the fact that they serve as a positive contributing factor in developing a better water quality control project along the Han River basin. The following are a few recommendations based on the data from the thesis: First, officials in charge of the Han River water quality control should pay attention to a careful screening of the opinions and recommendations from the academic circles and from the public should be made so that the government could better grasp the core issues in the environmental problems that require preventive and other necessary measures. Second, vigorous redistribution policies of population and industrial facilities away from the Seoul area should be pursued. Third, the government should refrain from revising or revamping too frequently the laws and decrees on the anti-water pollution, which is feared to cause undue inconveniences in the environmental administration. Fourth, a large-scale streamlining should be made to the existing administrative organization in an effort to do away with the inter- and intra-organizational friction. It is recommended that a secretariat for the Hah River basis conservation be established. Fifth, High-level administrative officials, with a thorough knowledge and vision on the Han River water quality control, should be prepared to better deal with the budgeting and personnel management for the Han River water pollution control not only at the control government, but also at the Seoul city municipal government levels. Environmental issues should be kept distinct from political issues. Environmental issues should not serve as a window-dressing for sheer political purposes. Sixth, the Hah River proiect should also include, along with the main Han River basin, those areas covering North Han River, South Han River, and the tributaries to the main river basin. The 'Han River Basin Water Quality Control Board' should be established immediately as a means of strengthening the current Han River basin water quality control policy. Seventh, in drawing up the Han River proiect, the administrative officials should be aware that Han River basin is a life line for those people in the region, providing them with not only a sheer physical space, but with a psychological living space for their everyday life.

현행 "건설기술관리법" 시행규칙의 환경보전비 세부산출기준에 따르면 환경보전비는 표준품셈 등을 이용하여 원가계산에 따라 산출하거나 원가계산이 곤란한 경우에는 공종별로 직접비에 요율을 적용하여 산정하도록 규정하고 있다. 그러나 원가 계산으로 산정할 경우, 현행 표준품셈에 환경보전비에 해당하는 항목이 일부 제한된 항목만 명시되어 있어 다양한 환경오염 방지시설의 설치 및 운영에 사용되는 제반비용을 반영하는 데 현실적인 제약이 있다. 아울러 요율을 적용하여 산정하는 경우에도 공종별로 획일적인 요율을 적용하도록 규정되어 공사현장의 입지여건 등에 따른 특성을 제대로 반영하지 못하고 있어 공사현장의 효율적인 환경관리가 어려운 실정이다. 따라서 본 연구에서는 도로공사 건설현장을 대상으로 공사규모, 현장 입지조건, 환경보전비 계상방식 등에 대하여 실태 조사 및 분석을 실시하여 이를 토대로 환경보전비의 적정 계상 방안을 제시하고자 한다.

Under the Korean Marine Environment Management Act (hereunder, the KMEMA), the duty to arrange spill clean-up equipments, including spill clean-up vessels, required by the article 67 of the KMEMA is in essence the provision of public goods since it is a precautionary or preventive measure for the efficient performance of oil spill cleaning up. Also the obligation to control marine pollution and the duty to arrange of anti-pollution measures imposed on polluters is the obligation imposed by the public law in accordance with "the Polluter-Pays Principle". Therefore, the execution of such obligations shall be accompanied by the minimum legal and institutional arrangements. On the other hand, judging whether to form the roles of the public and private sectors in providing public goods is basically a matter of policy decision. However, even if the private sector is allowed to participate in the provision of public goods, it is imperative that a minimum requirement be provided to secure the public interest. Although major countries allows polluters to conclude a preliminary contract with a civil anti-pollution management company, these civilian institutions are in principle constituted by the owners of oil storage facilities. Additionally it is worth noting that it operates as a non-profit organization. In particular, if the practitioner performs pollution control for commercial purposes, their profitability may depend on the size of the pollution, the period spent on pollution control, the size of the equipment and manpower mobilized in the pollution control, and so on. Considering the above problems, caution should be taken to allow marine environmental management companies to be un-limitedly entrusted with the responsibility of arranging measures such as pollution control. In order to allow the marine environmental management contractor to be entrusted for the assignment of duty to protect the marine environment, the marine environment management business should be expanded so that the marine pollutant management capacity satisfies the statutory control capacity. For this purpose, it is necessary to manage and supervise the maintenance and improvement of the control capability of the marine environment management business. It is also necessary to discuss the introduction of the grading system for the control ability of the civil control companies alike in major countries.

The purpose of this study is to provide the basic data in solving the environmental problem and in environmental education to University-students by searching the consciousness of Universitystudents' attitude toward and general views on the environmental protection. Out of total of 34 universities located in Seoul I randomly selected 11 universities and I again selected 700 university-students to answer my questionnaires. After that the questionnaires were added up by using computer. The major findings of this study are as follows 1. Regarding the overall conditions of the environmental pollution in our country, 91.1% of respondents marked "serious". 2. In suffering from Air pollution, 38.9% of respondents frequently suffered and 36.1% of them always suffered. Only 25.0% of total respondents represented their dislike about so-called "pollution-giving industries", which they do not wish to introduce for the sake of environmental protection. 3. In the source of information concerning the environment, 48.3% of them from the Television, 34.9% them from the newspaper. 4. In the attitude toward the participation for environmental protection, 28.0% of respondents expressed spontaneous attitude. 79.1% of total respondents have the basic desire to establish anti-pollution facilities and only 9.1% of total respondents have replied the ultimate responsibilities of enviironmental pollution. 5. Finally, only 13.3% of total respondents expressed their opinion that hte government officials willingly comply with students' request for better environmental protection and reflect them on their basic policies, and 32.1% of them said that the concerned government officials' attitude were positove and friendly toward the civilians, and 30.6% of them expressed their opinion that those concerned government officals ate holding professional and technicals know-which are necessaty and enough to the concerned field.

Bareboat Charter Register or Dual Registration under a Demise Charter scheme, does not in fact sanc-tion the alternative use of flags of different states, but rather it authorises the use of the flag of the coun-try where the ship is temporarily flagged only. Bareboat Charter Register is not intended to miselead third party states or persons dealing with the ship in respect of its nationality. Bareboat Charter Register gives a shipwner a more flexible and attractive package, for example mortga-ging facilities might be more attractive in one state because of its stronger laws relating to recovery of liens, whereas the manning requirements might be attractive in another state. By using Bareboat Charter Register, a shipwner/manager can avail himself of both advantage instead of settling for a compro-mise. Ships on a Bareboat charter Register would be subject to the safety, manning and anti-pollution require-ments of the second flag state and would carry that state's right to fly a flag of the original state be withd-rawn and the effect is to suspend the registration during the period of demise charter except in so far as relates to Title transactions.

산업화, 도시화로 인해 수자원의 오염이 악화 되면서 기존에 염소를 이용한 정수처리 방법으로는 깨끗한 물을 공급하는데 어려운 실정이다. 이에 오존을 이용한 고도정수 처리 시설의 도입이 증가하고 있다. 그러나 기존의 방수 방식 공법으로 사용되는 에폭시계 방수 방식제 및 스테인리스는 오존의 강력한 산화력으로 인해 열화되어 박리 등 문제 발생하였으며, 콘크리트까지 영향을 미쳐 내구성 저하의 원인이 된다. 이에 따라 본 연구에서는 내오존성 및 내화학성이 뛰어난 금속 패널을 기존의 시공법 보다 손쉬운 방법으로 시공하기 위한 방법으로 금속 용사 공법을 이용하여 수처리 시설 콘크리트 구조물의 열화를 원천적으로 방지하기 위한 마감공법 개발 연구의 일원으로 용사금속 종류 에 따른 내오존성 평가를 실시하였으며, 실제 하수처리장 환경에서의 전기화학적 안정성능 평가를 실시하였다. 실험결과 용사금속 Ti이 용사 후에도 내오존성이 뛰어난 것으로 나타났으며, 하수처리장 환경에서의 전기화학적 안정성능 평가 결과 용사금속 Ti가 $403.83k{\cdot}{\Omega}{\cdot}cm^2$의 가장 높은 분극저항을 나타남으로써 높은 수준의 내구성을 확보하는 것을 확인할 수 있었다.

해양오염방지협약(MARPOL 73/78)을 수용하기 위하여 제정 개정되어 은 해양오염방지법을 비롯하여 환경관련 국내법들을 살펴보고, 해양오염방지를 위하여 채택된 각종 국제협약들의 주요 내용을 국내법에 어떻게 수용하고 있는지를 검토하였다. 그리고 해양오염방지와 관련된 현행 국제협약의 내용 중에서 아직까지 국내법에 수용되지 않은 부분을 해양오염방지법에 수용하는 방안을 제시하였다. 최근에 선박대기오염방지규칙을 MARPOL 73/78의 부속서VI으로 채택함에 따라 국내에서는 대기환경보전법보다는 해양오염방지법에 이를 수용하였다. 72런던협약 및 96의정서(LC 72/96)의 주요내용을 해양오염방지법에 수용하고 있으나 72런던협약 부속서II의 특별주의물질, 부속서III의 해양투기허가증 발급기준 및 96의정서 부속서 I의 투기 가능물질에 관한 일부 내용이 수용되지 않고 있다. 기름오염대비대응협력협약(OPRC 90)의 주요내용은 해양오염방지법에 수용되어 있으나 항만 및 기름 취급시설 기름오염비상계획서와 국가긴급계획이 해양오염방지법에 수용되어 있지 않다. 유성혼합물이 선내에 잔류하는 해철용 유조선(폐선)을 개도국이나 후진국으로 이동하는 것을 방지하기 위하여 유해화학물질의 국가간 이동을 규제하고 금지하는 바젤협약의 관련 내용(폐유)을 해양오염방지법으로 수용하는 것이 바람직하다. 선박의 유해한 방오시스템 통제를 위한 국제협약을 유해화학물질관리법으로 수용하기 보다는 해양오염방지법으로 수용하여야 할 것이다. 국내에서 유기주석화합물(TBT)을 함유한 선박방오도료를 취급제한 금지물질로 분류함으로써 방오도료 국제협약을 국내의 유해화학물질관리법에 수용하고 있으나 방오도료 국제협약을 해양오염방지법으로 수용하는 것이 더 합리적일 것이다. 밸러스트수 국제협약을 수용하는 국내법이 없는 실정이므로 이 협약을 해양오염방지법으로 수용하거나 새로운 법을 제정하여 수용하여야 할 것이다.알고리즘을 제안하였다. 시그널링 트래픽은 history cache가 성공시 약 48%의 traffic이 감소되었고 history cache 실패시 약 기존 핸드오버 보다 약 6%의 traffic이 증가되었다.구들에 비해 월등히 좋은 결과를 나타내었다(p<0.05). 이 시험에서는 첫 번째 시험에서 보이지 않았던, 생체중에 대한 복강 지방 비율이 현저하게 감소한 것으로 나타났다(p<0.05). 본 실험 결과 육계사료에 희토의 첨가는 육계의 성장을 촉진하였으며, 사료 요구율 개선하였다. 이외에도 복강지방이 낮아지는 경향을 보였지만 일관성이 없었으므로 추후의 연구가 필요하다.향은 앞으로 좀더 연구가 필요하다.로 생각되며, 이에 따른 적극적인 anti-reflux 수술에 대한 고려도 필요할 것으로 생각된다.$14.7{\pm}2.7$ mL로 각 군 간에 통계적인 유의성이 있었다(p<0.05). 혈청내 칼륨 농도는 I군에서 II군에 비해 소생술 후 의의 있게 높았으며(p<0.05), 포도당 농도는 II단계의 I군에서 타군과 비교하여 현저히 낮았다(p<0.05).

Background: Indoor air pollutants are caused by a number of factors, such as coming in from the outside or being generated by internal activities. Typical indoor air pollutants include nitrogen dioxide and carbon monoxide from household items such as heating appliances and volatile organic compounds from building materials. In addition there is carbon dioxide from human breathing and bacteria from speaking, coughing, and sneezing. Objectives: According to recent research results, most indoor air pollution is known to be greatly affected by internal factors such as burning (biomass for cooking) and various pollutants. These pollutants can have a fatal effect on the human body due to a lack of ventilation facilities. Methods: We fabricated a polydopamine (PDA) layer with Ti substrates as a coating on supported glass fiber fabric to enhance its photo-activity. The PDA layer with TiO₂ was covalently attached to glass fiber fabric using the drop-casting method. The roughness and functional groups of the surface of the Ti substrate/PDA coated glass fiber fabric were verified through infrared imaging microscopy and field emission scanning electron microscopy (FE-SEM). The obtained hybrid Ti substrate/PDA coated glass fiber fabric was investigated for photocatalytic activity by the removal of ammonia and an epidermal Staphylococcus aureus reduction test with lamp (250 nm, 405 nm wavelength) at 24℃. Results: Antibacterial properties were found to reduce epidermal staphylococcus aureus in the Ti substrate/PDA coated glass fiber fabric under 405 nm after three hours. In addition, the Ti substrate/PDA coated glass fiber fabric of VOC reduction rate for ammonia was 50% under 405 nm after 30 min. Conclusions: An electron-hole pair due to photoexcitation is generated in the PDA layer and transferred to the conduction band of TiO₂. This generates a superoxide radical that degrades ammonia and removes epidermal Staphylococcus aureus.
