This study is to investigate the problems of pollution caused by drycleaning solvents. From the problem of each solvents, safety count-step have to set up. It is following. 1) Solvent: Smong phenomenon of optical chemistry. It has to develop safety tumbler that is attached retrievable device. 2) Perchloroethylene: Pollution of underground water and cause of cancer. Considering the influence on environment and human bing, it has to set up more strong safty plan than now. 3) Chlorofluorocabon : Destory of ozon layer and green house effect on earth. It is being to stop the production until the early part of the year 2000. So it is developing a substitute for chlorofluorocarbon. 4) 1,1,1-trichloroethane : Pollution of underground water and destroy of ozon layzer. At the end of the year 2004, there will be end production of it.

본 논문에서는 고도정수처리설비에 활용되는 오존접촉조의 반응 특성을 퍼지 모델 형태로 표현하는 방법을 제안한다. 퍼지모델에 사용될 입력 및 출력 변수들은 오존처리의 목적과 정수장의 수질관리항목을 기준으로 선정하였다. 제안된 입력 변수들은 용존유기탄소농도, $UV_{254}$흡광도, 과망간산칼륨소비량, 주입오존농도, 수온 및 접촉시간이며, 출력변수들은 용존유기탄소농도, $UV_{254}$흡광도 및 과망간산칼륨소비량이다. 입력변수들에 대한 소속도 함수들은 삼각형 형태로 설계하였으며, 파이롯플랜트에서 취득한 조업데이터를 참고하여 소속도를 결정했다. 퍼지모델의 결론부는 선형식 형태로 설계하였으며, 선형식에 포함되는 상수들은 조업데이터를 이용하여 최소자승법으로 구했다. 또한 출력 변수들간에 상호 영향이 없다는 특성으로부터 전체 퍼지모델로을 각 변수별로 독립적인 기능을 갖는 3개의 부분 퍼지모델로 분할하여 설계함으로서 계산과 이해의 편리를 도모하였다. 모의실험을 통해 제안된 퍼지모델의 타당성을 확인해 본 결과, 모델의 튜닝시에 사용한 입력 데이터에 대해 퍼지모델의 출력이 조업데이터와 거의 동일함을 알 수 있었다.

Narcissism is a pathological phenomenon and narcissistic subject always needs to put itself on the top and has interest in nothing but its own determination. The protagonist of Adversary by ?mmanuel Carr?re does pay careful attention to what others are thinking of him while he does not distinguish difference between object of love and himself. So he can be allegedly narcissistic subject. And it can be said that the behaviors of Mary in the movie Under the sand by Ozon are included in narcissism in that narcissistic subject has the characteristics that idealizes the object of libido. However, in this study, the heroine is examined based on such a point that the object of love and extreme idealization incline toward others. We call this case reverse-narcissism. In Part 2, it is investigated what relation narcissism as an unconscious psychological tool has with Oedipus complex, which plays an important role in forming human psyche. For instance, disappointment caused by prohibition at the oedipal stage is too severe, which creates superego and its idealization to protect in such a way that narcissistic regression can not be done. Cases of extremely big gap between ego and ideal type are perversion, impostor, mania, paranoia, etc, where narcissistic and oedipal elements are combined to affect.

This paper describes the results of characteristics on the tracking resistance, hydrophobicity and dielectric properties of silicone rubbers used for outdoor insulation with ozone ageing. The tracking and ozone ageing tests for this purpose ware made in according to IEC 587 and ASTM D 1149, respectively. Additionally, we investigated the surface structure of the silicone rubbers with FT-IR and SEM. From the test results, it is proven that the higher the degree of ozon ageing, the worse tracking characteristics.

The pulsed poser system has been widely used to many applications, such as E/P(Electrostatic Precipitator), DeNox/DeSOx power system, ozon generator, etc. A pulse energy efficiency for load depends on the rising time, peak value, pulse duration and impedance matching, etc. The pulse generator generally required for short pusle duration and high peak value was forced to consider its volume and economy. In this study, developing a compact pulse generator that applied for cascading method to be made of two pulse transformers, we compared cascading voltage with non cascading one by applying the pulse energy to load. Adopting cascading technique to pulse transformer, we found that average cascading voltage was about 60[%] of theoretical value. Maximum cascading ratio was calculated at 60 times compared with non cascading voltage.

The protection of the environment is one of today's key demanding international activities and interests. All of aspects including industry, economy and society should be changed into environmental friendly industries. The building is not exception in this trend. What is not generally realized is that building, in the lifecycle of construction, use and demolition, account for large construction, not considered with environment impact and conservation in the lifecycle. Expecially, the construction materials and components used in the construction stage has much embodied energy. And much $CO_2$ emit on the production of the construction material and component. The energy use and $CO_2$ emission would continuously diminish the limited natural resources and impact the environment such as ozon layer destruction. In this paper, it studied the estimation of the amount of energy use and $CO_2$ emission in the building construction stage, it would provide the estimation process and applied with the multifamily housing.

Purpose: This study is about photocatalytic technology and plasma oxidation-reduction technology. To the main cause of exposure to odor pollution, two deodorization techniques were applied to develop a module with higher removal efficiency and ozone reduction effect. Research design, data and methodology: A composite module was constructed by arranging two types of dry deodorization equipment (catalyst, adsorbent) in one module. This method was designed to increase the responsiveness to the components of complex odors and the environment. standard, unity, two types of oxidizing photo-catalyst technology and plasma dry deodorization device installed in one module to increase the potential by reduction to 76% of ozone, 100%, and 82%. Results: The complex odor disposal efficiency was 92%. Ammonia was processed with 50% hydrogen sulfide and 100% hydrogen sulfide, and ozone was 0.01ppm, achieving a target value of 0.07ppm or less. The combined odor showed a disposal efficiency of 93%, ammonia was 82% and hydrogen sulfide was 100% processed, and ozone achieved a target value of 0.07 ppm or less. Conclusions: Ozone removal efficiency was 76% by increasing Oxidation-Reduction Reaction(ORR). The H2S removal efficiency of the deodorizer was higher than that of the biofilter system currently used in sewage disposal plants.

영화 속에 내재된 이중적 의미는 문학에서 말하는 중의법(重義法)과 같은 맥락으로 해석된다. 중의법이란 어느 한 단어나 문장이 두 가지 이상의 의미로 해석될 때를 말한다. 영화에서도 한 인물의 행동이나 소도구 혹은 의상이 의미하는 바가 두 가지 이상의 의미를 가지고 관객과 대면한다. 프랑스의 유명 감독 프랑수아 오종은 "감독은 언제나 자기가 만든 최신작에 역행하는 영화를 만들어야 한다."고 했다. 이 말의 의미는 영화는 개혁을 추구하지 않으면 안 된다는 감독의 철학이다. 영화가 금기를 깨야한다는 것은 사실 영화정신의 밑바탕이기도 하다. 영화는 항상 금기에 도전했고 진보를 선도했다. 서양 영화의 금기는 우리나라의 도덕과 윤리수준과는 좀 더 치열한 부분이 존재한다. 그들의 금기는 기독교의 신성과 정통성을 부정하는 일이다. 특히 예수 그리스도의 신성을 부정하는 영화가 많은 사람들에게 회자되면서 갑론을박을 끌어내기에 충분했다. 본 연구에서 톰 튀크베어 감독의 영화 "향수"를 텍스트로 선택하여 이 영화 속의 고도의 치밀하고 전략적인 이중적 내용을 파헤쳐 관객을 교묘히 기만한 서양의 금기를 분석하고자 한다.

1999학년도부터 지난 3년 동안 시행된 대학수학능력시험에서 공통과학 중 화학 영역 문항에 대한 학생들의 응답을 조사하였다. 내용 영역과 탐구 과정에 따른 문항수, 내용 영역과 탐구 과정에 따른 평균 정답률, 정답률 수준에 따른 문항 분포, 정답률이 높거나 낮은 문항 등을 분석하였다. '환경' 영역에서의 문항수가 매우 적었는데, 특히 '오존층'에 대해서는 한문항도 출제되지 않았다. 가장 어려운 내용 영역은 '환경' 영역의 '산성비'였다. 탐구 과정별로는 '자료 분석 및 해석'에서 가장 많은 문항이 출제되었고, '문제 인식 및 가설 설정'이 가장 어려운 것으로 나타났다. '아주 어려운 수준'의 문항은 하나도 없고. '쉬운 수준'이나 '아주 쉬운 수준'에 해당하는 문항이 많았다. 학생들은 여러 가지 개념이나 지식을 요구하는 문항을 해결하는 데에 많은 어려움을 느꼈고, 저학년에서 다루어진 개념만을 요구하는 문항을 쉽게 해결하였다. 교육학적 함의에 대해 논의하였다.
