In former times the protection of our environment didn't play an important role due to the fact that emissions and effluents were not considered as serious impacts. However, opinions and scientific measurements meanwhile confirmed that the impacts are more serious than expected. Thus measures to protect our earth has to be taken into consideration. A part of these measures in the Environmental Impact Assessment (EIA). One of the most important parts of the EIA is the collection of basic datas and the following evaluation. Experience out of the daily business of Gerling Consulting Group shows that the content of the EIA has to be revised and enlarged in certain fields. The historical development demonstrated that in areas in which the population and the industrial activities reached high concentration there is a high necessity to develop strict environmental laws and regulations. Maximum values of the concentration of hazardous materials were fixed concerning the emission into and water. Companies not following these regulations were punished. The total amount of environmental offences increased rapidly during the last decade, at least in Germany. During this development the public consciousness concerning environmental affairs increased as well in the industrialized countries. But it could clearly be seen that the development in the field of environmental protection went into the wrong direction. The technologies to protect the environment became more and more sophisticated and terms as: "state of the art" guided more and more to lower emissions, Filtertechnologies and wastewater treatment for example reached a high technical level-but all these sophisticated technologies has one and the same characteristic: they were end-of-the pipe solutions. A second effect was that this kind of environmental protection costs a lot of money. High investments are necessary to reduce the dust emission by another ppm! Could this be the correct way? In Germany the discussion started that the environmental laws reduce the attractivity to invest or to enlarge existing investments within the country. Other countries seem to be not so strict with controlling the environmental laws which means it's simply cheaper to produce in Portugal or Greece. Everybody however knows that this is not the correct way and does not solve the environmental problems. Meanwhile the general picture changes a little bit and we think it changes into the correct direction "End-of-the-pipe" solutions are still necessary but this word received a real negative touch and nobody wants to be brought into connection with this word received a real negative touch and nobody wants to be brought into connection with this word especially in connection with environmental management and safety. Modern actual environmental management starts in a different way. Thoughts about emissions start in the very beginning of the production, they start with the design of the product and modification of traditional modes of production. Basis of these ideas are detailed analyses of products and processes. Due to the above mentioned facts that the public environmental consciousness changed dramatically a continous environmental improvement of each single production plant has to be guarantied. This question is already an important question of the EIA. But it was never really checked in a wholistic approach. Environmental risks have to be taken into considerations during the execution of an EIA. This means that the environmental risks have to be reduced down to a capable risk-level. Environmental risks have to be considered within the phase of planning, during the operation of a plant and after shut down. The experience shows that most of the environmental relevant accidents were and caused by human fault. Even in highly protected plants the human risk-factor can not be excluded during evaluation of the risk-potential. Thus the approach of an EIA has to regard technical evaluations as well as organizational thoughts and the human factor. An environmental risk is a threat to the environment. An analysis of the risk concerning the organizational and human aspect however never was properly executed during an EIA. A possible solution could be to use an instrument as the actual EMAS (Environmental Management System) of the EC for more accurate evaluation of the impact to the environment during an EIA. Organizations or investors could demonstrate by an approved EMAS or even by showing their installment of EMAS that not only the technical level of the planned investment meets the requested standards but as well the actual or planned management is able to reduce the environmental impact down to a bearable level.

본 연구에서는 음폐수를 대상으로 5 톤/일 처리규모의 막결합형 2상 혐기성 소화(TPADUF) 플랜트를 운영하며 유기물 제거효율 및 메탄 발생량을 파악하고, 소화가스를 이용한 발전 가능성 및 분리막 적정 운영방안을 검토하였다. 고온 산발효조, 중온 메탄조 및 UF 막으로 구성된 처리 시스템에서 평균 TCOD가 150 g/L인 음폐수를 유기물 부하 11.1 g COD/L/d까지 증가시키며 처리한 결과 최종 유출수의 TCOD는 6 g/L 이하이었으며, TCOD 및 SCOD 제거효율은 모두 95% 이상이었다. 소화 가스의 메탄 구성비는 65%이었으며, 회수된 메탄량은 시스템에서 일부 가스가 누출되었음에도 39 $m^3/m^3$ 음폐수 주입량, 260 $m^3$/톤 COD유입량, 또는 270 $m^3$/톤 COD제거량 이었다. 소모된 가스량 당 발전량은 0.96 kWh/$m^3$ 가스, 또는 1.49 kWh/$m^3$ 메탄으로 다소 낮았으나 이는 소용량 발전기(15 kW급)의 저효율에 기인한 것이다. 분리막은 평균 flux 10 L/$m^2$/hr에서 운전하였으며, 운전 중 flux가 감소하였을 때는 물 또는 화학적(NaOCl)세정을 실시하여 회복시킬 수 있었다. TPADUF 플랜트에서는 메탄조 내액 또는 분리막 농축액을 산발효조로 반송함으로써 산발효조의 pH를 별도의 약품 주입 없이 적정 수준을 유지할 수 있었으며, 산발효조에서 부분적인 메탄생성을 통해 메탄조의 유기물 부하를 낮추는 효과도 있었다.

Lots of pollutants typically originating from urban transportation are accumulating on the paved surfaces during dry periods and are washed-off directly to the river during a storm. Also, paved surfaces are contributing to increase in peak flows and volume of stormwater flows. These are the main reasons why the water quality of rivers and lakes remain polluted and still below standards. Currently, several management practices are being applied in developed countries but the design standards are still lacking. This research was conducted to develop a treatment technology that can be useful to address the problems concerning runoff quality and quantity. A lab scale infiltration device consisting of a pretreatment tank and media zone was designed and tested for various flow regimes characterizing the low, average and high intensity rainfall. Based on the experiments, the high intensity flow resulted to increase in outflow event mean concentration (EMC) of pollutants, about twice as much as the average outflow EMC. However, 78 to 88% of the total suspended solids were captured and retained in the pretreatment tank because of sedimentation. The removal of heavy metals such as zinc and lead was greatly affected by the vertical placement of woodchip layer prior to the media zone. It was observed that the high carbon content (almost 50%) in the woodchip provided opportunity for enhancing its uptake of metal by adsorption. The findings implied that the reduction of pollutants can be greatly achieved by means of proper pretreatment to allow for settling of particles with a combination of using high carbon source media like woodchip and a geotextile mat to reduce the flow before filtering into the media zone and finally discharging to the drainage system.

It is widely recognized that primary health care in the community is one of the most important and effective health measures in these days. However, it is reality that unsatisfactory health care system, ineffective utilization of health care by the community people in the rural area are hampering better understanding for primary health care. Therefore promoting health for the rural people and increasing understanding about primary health care, the baseline survey in the community focused in examination for safe community water supply was carried out. The survey was conducted through August 25-31, 1986 in order to find out health problems and relevant factors and to define the demographic characteristics of $^*$Sanpuk village, Kumsa-Myun, Yuju-Gun, Kyunggi-Do, Korea. Household survey was carried out for every home by trained interviewers. The major results are found out as follows : 1) 84.2%(400 houses) of total households were surveyed because 15.8%(75 houses) were unable to survey due to either refusal against interview or absence of family. These 400 households were composed of 1,697 residents(male:830, female 867). Educational level of respondents showed 34.1% as elementary school graduated. Religion distribution showed Buddism(23.8%) as the most dominant. 50.7% of respondents married in the area. 2) Most households(91.5%) have lived in their own house in Sanpuk area. Average family size showed 4.3. More than half of residents(64.2%) have used public supplied water tap. Only 1.5% of the households had a flush toliet. The rest of households have still used primitive insanitary latrines. 3) 32.5% of residents have used gas burner for cooking and for heating in the house, and the coal briquet were used for boiler. Lack of convenient public transportation was the chief complaint for their day life. 4) Each household occupied 1,990 pyungs of rice paddy and 1,170 pyungs of ordinary field in average. Beside farming products, mushroom was the highest product. 5) Sixth percent of households in the survey area regularly participated in community meeting one hand and on the other hand 39.5% never participated. Most of respondents closely contacted with their neighbours and they seemed very friendly each other. 6) The prevalence rate of illness and injury during recent 15 days showed 48.3 per 1,000. The prevalence rate of chronic illnesses during the past one year showed 74 per 1,000. Injury and accident lead the higher portion(22.0%) in the former and in the latter pain(arthritis, back-pain) showed 27.0% as the dominant sickness. 87.8% of the ill residents in the former received medical treatment. As the most frequently utilized medical facility, the clinic or hospital were counted. Among the residents suffering from chronic illnesses, 77.3% in Sanpuk area get some kind of medical treatments and they rarely utilized the clinic or hospital. The reason why the patient did not receive any medical care was found out the fact that symptoms of illness was light or mild and economic problems was serious. 7) Average age of marriage showed 21.6 years old in the women and the average duration of marital period was shown for 15.1 years. The married woman in reproductive age in Sanpuk area had experienced pregnancies 4 times in the aver-age including 0.7 time of pregnancy in average were interrupted by induced abortion and 0.3 time by spontaneous abortion respectively. The practicing rate of the family planning of the married woman during reproductive ages showed 70.7% and the tuballigation was found out as the most frequently used contraceptives. 8) Among woman who has children under 2 years old, 70.0% had received the prenatal care for the last pregnancy. However, the average number of prenatal care visitis per woman showed 3.3 times. Fifty-two % of woman who received the postnatal care for the last delivery showed only 37.5%. 9) Immunization rate of the children under 2 years old showed relatively high and looked successful. The breast feeding for these children showed dominantly in the most. Most of the mothers in Sanpuk area had started the supplementary diet during weaning period of their infants of 6th and 7th month after birth. * : Sanpuk area is a demstration area for community development which has been supported by the Community Development Foundation during the part 10 years. The village is relatively closer to urban area such as Seoul, However, it has a similar characteristics shown as a remote village because of geographical location and inconvenient transportation at present.

골프장은 인공적으로 건설되어 지고 관리되므로 당연히 환경의 변화가 생성된 곳이므로 건설방식이나 관리 방법에 따라 코스 내 토양 미생물 군집 구조의 특이성이 있을 것이다. 현재 제주도에서는 농약 용탈 저감방안으로 골프코스 그린지반구조에 농약 흡착층을 설치하고 그 재료로 흡착성능이 우수한 입상 활성탄 1등급을 사용할 것을 환경 영향평가서에 명시하고 있다. 본 실험은 활성탄이 처리된 제주도 A, B 골프장을 대상으로 토양에서의 화학적 특성변화와 미생물 군락변화를 분석하였다. 2007년 4월, 6월, 8월 10월에 걸쳐서 총 박테리아 수, 총 곰팡이 수, 수분함량 및 토양 이화학성(pH, EC, NO3-,NH4+ 및 P2O5)의 변화를 그린과 페어웨이에서 깊이별(표토:0-15cm, 심토: 15-30cm)로 조사되었다. 그 결과, 활성탄의 시용이 수분 보유 능력, 토양산도, 전기전도도에 긍정적인 영향을 보였으나, GAC의 물질의 수착 능력에 의하여 유효 양분들을 많이 보유하는 데 도움이 될 것이라 예상하였으나, 본 실험에서는 가용성 질산과 암모늄, 및 인산의 농도를 높이는 효과는 없었다. 토양 미생물 실험에 있어서는 총 박테리아 및 총 곰팡이의 시기적 변화가 다양성을 보였다. 이러한 현상은 농약의 시용에 따라 직접적인 관련이 있을 것으로 예상되었으나, 총 곰팡이/총 박테리아 비(F/B ration) 는 활성탄을 혼합한 토양 심토(15-30cm)에서 일정한 수치를 유지하였다. 따라서, GAC 토양층의 설치 방법이나 시비와 시약 등이 미생물군집의 변화에 영향을 주며 이는 농약의 시용이 잔디관리에 큰 변수로 작용한다는 것을 시사한다.

본 연구에서는 연안오염총량관리가 시행되고 있는 시화호 유역에서 비점오염 형태로 유입되는 중금속 유출 특성, 오염도 및 위해성을 평가하기 위하여 반월 스마트 허브(산업단지)에 위치한 강우유출수 내 용존성과 입자성 중금속(Co, Ni, Cu, Zn, Cd 및 Pb)을 조사하였다. 용존성 Co와 Ni은 강우초반에 농도가 높고 이후 감소하는 경향을 보였으나, 나머지 용존성 중금속과 입자성 중금속은 강우량 증가에 따라 농도가 큰 폭으로 증가하는 경향을 보였다. 총 중금속 중 입자성 중금속이 차지하는 상대적인 비율은 Pb이 97.2%로 가장 높고 Cu>Cd>Co>Zn>Ni순이었으며, 입자-용존 분배계수($K_d$) 결과는 강우유출수 내 존재하는 Pb는 다른 중금속에 비해 빠르게 입자형태로 제거되는 것으로 나타났다. 본 연구를 통해 1일의 강우 이벤트 동안 2개의 토구를 통해 유출되는 총 중금속의 유출량은 Co 2.21 kg, Ni 30.5 kg, Cu 278.3 kg, Zn 398.3 kg, Cd 0.39 kg 및 Pb 40.0 kg로 나타났다. 연안오염총량관리제도가 시행되고 있는 시화호의 유역면적, 연간 강우량 등을 고려할 때 막대한 양의 중금속이 비점오염의 형태로 시화호로 유입되고 있음을 알 수 있었다. 무엇보다 강우유출수 내 용존성 Ni, Cu 및 Zn의 평균농도는 급성 독성을 나타내는 수질기준(급성 단기기준)를 초과하고 있으며, 입자성 중금속 역시 모든 원소가 배경농도에 비해 농축도(오염도)가 매우 높고, 국내 퇴적물 관리기준(PEL)을 큰 폭으로 초과하고 있어, 주변 해역 환경 및 생태계에 악영향을 미칠 것으로 판단된다.

pH와 산화환원(酸化還元) 전위(電位)가 토양(土壤)의 규산흡착(珪酸吸着)에 미치는 영향(影響)을 보기위하여 두개의 필리핀토양과 두개의 한국 토양을 사용하여 실내(室內)에서 실험하였다. 규산의 등온흡착(等溫吸着)은 등온흡착(等溫吸着)의 분류체계(分類體系)에 의하면 약(弱)한 L-type(점근선적(漸近線的) 증가(增加))을 지닌 C-type(직선적(直線的) 증가(增加))에 속(屬)하였다. 규산의 등온흡착(等溫吸着)은 Freundlich와 Tempkin 등온흡착식(等溫吸着式)에 잘 맞았으나 Langmuir 등온흡착식(等溫吸着式)에는 잘 맞지 않았다. Molybdenum-blue 법(法)에 의한 규산 발색시(發色時) 환원(還元) 및 낮은 pH 조건(條件)에서 $Fe^{2+}$ 이온에 기인(起因)된 것으로 보이는 발색장해(發色障害)가 나타났다. Freundlich 식(式)의 절편(切片), Tempkin 식(式)의 기울기, "Silica reactivity"와 C-type slope" 등 4개의 지표(指標)를 규산흡착에 미치는 처리효과 판정(判定)을 위한 지표(指標)로서 검토(檢討)하였다. 이들중 "Silica reactivity"와 C-type slope"는 본(本) 실험에서 제안(提案)된 지표(指標)였다. 4개의 지표(指標)중 "C-type slope"가 가장 좋은 지표(指標)로 판명되었다. C-type 등온흡착(等溫吸着)의 직선회귀(直線回歸)는 Freundlich와 Tempkim식(式)과 거의 동일(同一)한 높은 직선회귀(直線回歸) 상관계수(相關係數)를 보였다. 또한 pH와 log(C-type slope)는 고도(高度)의 직선관계(直線關係)를 보였다. C-type slope를 지표로 이용한 처리효과 분석(分析)결과 pH와 토양종류(土壤種類)는 규산의 토양흡착에 크게 영향을 미치는 반면 산화환원(酸化還元) 전위(電位)의 효과는 없었다. 모든 형태(形態)의 Al과 Fe 및 OM이 규산흡착과 고도(高度)의 상관(相關)을 보였으며 그 중 $Fe_d$가 기여도(寄與度)가 가장 큰 성분(成分)으로 나타났다. 산화(酸化)알루미늄의 분별정량법(分別定量法)이 확립(確立)되어 있지 않은 결과(結果) Al의 기여도(寄與度)는 불확실(不確實)하게 나타나는 것으로 보였다.

This study was designed to develop a conceptual framework for the curriculum and develop the details of the learning content for the education of Community Health Practitioners (CHPs). Since education programs for CHPs started 10 years ago, concepts related to CHP services have changed because of changes in society. The objectives of the study were as follows : 1) to analyse the usefulness of the present education program for CHPs, 2) to analyse the Job performance and self -confidence of the CHPs, 3) to identify the health needs of the clients served by the CHPs and the community problems related to health. 4) to develop a conceptual framework for the curriculum, for the education of CHPs, 5) to develops details for the learning content of the education program for CHPs. Phase I of the study was conducted by questionnaires to 150 CHPs who have worked in remote rural areas for more than 2 years. Among them, 147 responded. Data was collected from August 16, to August 25, 1990. In order to identify the health needs of the community people, research within the last five years was reviewed and analyzed. The data on 1, 842 communities gathered by the WHO Nursing Collaborations Center of the College of Nursing, Yonsei University was utilized to identify community problems related to health and the self - confidence in job performance of the CHPs. Psase II of the study consisted of a workshop with 13 professionals including Community Health Practitioners to evaluate the existing education program and a conceptual framework of the curriculum for the job education of CHPs. The results of the study are Summariged below : 1. The only 26 among 45 content items of the education program related to job skills was used by 80% of the responding CHPs. The knowledge of $\ulcorner$Networking community organization$\lrcorner$ was used by only 53.7% of the respondents. Educational content about $\ulcorner$Mental disease$\lrcorner$ was used by less than 50% of CHPs because of a knowledge deficit. 2. The CHPs reported that their activities concentrated on clinical services during the last six months. The survey showed that they seemed to neglect the activities for health promotion and disease prevention. Thus, $\ulcorner$Education for community loaders$\lrcorner$(15.9%), $\ulcorner$Activity for eavironmental health$\lrcorner$(16.3%) and $\ulcorner$Social work for needey people$\lrcorner$(23.3%) were done by less than 30% of CHPs. 3. More than 90% of CHPs reported being self - confident for the activities of $\ulcorner$Health education and counselling$\lrcorner$, $\ulcorner$Medicine prescription$\lrcorner$ and $\ulcorner$Immunization$\lrcorner$. But 50% of CHPs reported that they were not have self - confident in $\ulcorner$Management of water and environmental health$\lrcorner$ and only 25.6% of CHPs could insert an IUD independently. 4. It was identified that respiratory diseases and the gastrointestinal diseases were most common problems for the community people, followed by musculoskeletal and skin problems. 5. The community problems were classified into eight categories : physical environmental problems, environmental hygiene, health problems, health behavior, social problem, lack of resources, financial problem and the problems of the cultural and value system. 6. The conceptual framework consisted of the target population and their health status, nursing process working site and primary health care services such as health promotion, disease prevention, treatment and rehabilitation. 7. The contents of curriculum of education program for CHPs were formulated from the results of this study.

최근 국제적으로 풍력, 태양광, 파도, 연료전지 등의 친환경 신재생에너지 개발이 활발하다. 특히, 해상에서의 풍력발전단지 개발은 대형화를 통한 단가 절감, 고품질의 풍력자원 활용, 발전기로 인한 소음 피해 최소화를 위해 해안에서 멀리 떨어진 위치에 대규모 부유식으로 건설되는 추세이다. 풍력발전단지의 개발은 해사안전법에 의한 해상교통안전진단제도에 따른 평가가 필요하다. 풍력발전단지의 평가는 해당 수역의 체계적인 개발, 관리, 활용을 위해 선과 면적 개념을 모두 적용하여 수행되어야 하며, 이를 위한 평가 방법과 기준이 개발되어야 한다. 이 연구에서는 해상풍력발전단지처럼 해양 공간을 평가할 수 있는 해상교통조사방법과 평가에 대한 적절한 기준을 수립하고, 이를 시스템적으로 처리할 수 있는 방안에 대해서 연구하였다. 먼저 해상교통조사를 위해 AIS와 레이더를 이용한 이동식 해상교통데이터 수집장치를 설계하였다. 그리고 선과 면적의 개념을 모두 적용한 해상교통 항적도, 밀집도, 경로 분석을 제안하였다. 해상교통밀집도는 Grid-cell의 크기를 조절하여 단위 cell에 대한 공간적, 시간적 점유율을 구분하고 해상교통 경로 분석은 해상을 통항로 또는 작업 공간으로 사용할 때를 구분하여 선박의 이동 패턴을 평가할 수 있도록 제안하였다. 최종적으로 시스템적인 해상교통데이터의 수집과 평가가 가능한 해상교통안전평가솔루션의 개념설계를 수행하였다. 이는 자동적인 해상교통데이터의 수집 저장 분류를 통해, 데이터 누락이나 오표기와 같은 인적 오류를 최소화하고 해상 공간의 용도에 따라 선과 면적 개념을 반영하여 분석함으로써 신뢰성 있는 해상 공간의 평가가 가능하게 한다.
