Urban sanitary sewer systems can aid in preventing inundation, and can improve civil health by effectively disposing stormwater and wastewater. However, since sewage odor can cause adverse effects, numerous technical and administrative studies have been conducted for reducing such odor. European countries and the United States of America (USA) built modern sewer systems in the late 19th century, and have since been endeavoring to eliminate sewage odors. Several cities of the USA, such as Los Angeles (LA) that has a separate sewer system and San Francisco (SF) that has a combined sewer system, have produced and distributed odor control master plan manuals. Features common in the odor reduction plans of both these cities are that the odor reduction programs are operated in all the respective local regions and are supported by administrative systems. The primary aspectual difference between the two said programs is that the city of LA employs a sewage air purification system, whereas the city of SF controls the emission of major odor causing compounds. Compared to the existing sewer odor reduction systems of these two cities, South Korea is still in the initial phase of development. Through technical studies and policy implementations for sewer odor reduction, a foundation can be laid for improving the civil health quality.

혼성성(hybridity)' 이라는 용어는 최근 초국적 이주자들과 같은 유목민적 주체들에 관심을 가지는 사회이론적 연구들의 주요용어로 등장하였다. 특히, 탈식민주의적 정치와 관련하여, 혼성성은 담론의 경계에 도전하고 권력이 내재화된 역사와 문화를 비판적인 차원에서 새롭게 기술할 수 있는 제3의 공간을 제공할 수 있을 것으로 인식되고 있다. 그러나 본 논문은 혼성적인 주체의 위치성이 오히려 새로운 문화 담론을 생산하고 새로운 헤게모니를 잉태하는 데에 용이하게 작용할 수 있음을 지적한다. 본 논문은 의도된 의식적 혼성성을 경험된 유기적 혼성성으로부터 분리함으로써 탈식민주의에서 혼성성의 정치가 가지는 이중적 본질을 살펴보고자 한다. 경험적인 수준에서, 본 연구는 로스앤젤레스 한인타운에 입지한 '영빈관' 이라는 레스토랑의 시대공간적 변화를 혼성성의 관점에서 읽음으로써 어떻게 탈정치화된 민족성을 드러낼 수 있는가에 주목한다. 둘째, 본 논문의 후반부에서는 지난 10여 년간 로스앤젤레스 한인타운 내에서 새로운 헤게모니를 형성하고 있는 한국계 엘리트 및 전문가 계급들이 소위 '1.5세대' 라는 혼성성의 담론을 통하여 어떻게 그들의 정치적인 지위를 강화하는가에 주목한다. 결론적으로 본 논문은 혼성성이 새로운 대안으로서의 제3의 정치적 지위를 욕망하기보다는 사회공간적 경계들에 도전하는 비판전략의 하나로서 '스스로를 해체하기 위한 개념'으로 이해되어 야 함을 지적한다.

오늘날 세계주의의 시대에 점차 많은 도시들은 재스케일화의 전략을 통해 국가적 차원에서 이탈된 광역생산네트워크를 구축하고 있을 뿐만 아니라 도시 내의 국지적 지리를 보다 효율적으로 통제하기 위한 도시 거버넌스를 재정비하고 있다. 이러한 맥락에서 도시재개발은 도시정부가 통치제도를 강화함으로써 세계화에서 비롯된 노후주택지구, 노동계급의 게토, 우범지역 등과 같은 위협적인 공간변수들을 제거하고 이 공간들로부터 교환가치를 증식, 전유하는 세계적 전략으로 이해된다. 본 논문은 이러한 실천을 '세계도시화(glurbanization)'의 한 과정으로 보고, 특히 세 가지 차원에 주목한다: 첫째는 도시정부가 빈곤을 '고안'해내기 위하여 도시재개발의 담론을 사용하는 방식, 둘째는 도시정부가 그 담론을 제도화하여 구체적인 재개발 프로젝트를 구현하는 방식, 셋째는 제도화된 도시기구들이 재개발 담론 및 담론적 실천을 그들의 목적에 맞게 전유하는 방식을 살펴본다. 본 연구는, 경험적으로 캘리포니아 재개발법과 로스앤젤레스 도시재개발국에 초점을 두어, 이들이 어떻게 소위 '황폐구역'으로 정의된 도시공간에서 토지수용권과 증분세금수입이라는 도구를 통해 어떻게 가치를 짜내는지를 분석한다. 방법론으로는 담론분석과 제도민족지법을 사용한다. 결론적으로, 본 논문은 황폐구역으로 낙인찍힌 도시 공간들이 '공공의 보건과 안전'이라는 담론을 통해 재개발기구의 덫에 가두어지고 있으며. 이들 빈곤지역으로부터 증식, 추출된 교환가치는 외부 투자자들, 개발업자들 및 재개발기구 그 자체의 자원으로 전유되고 있다는 점을 비판한다.

Water content and strong acidity are estimated for ambient particles measured between Fall, 1991 and Summer, 1992 in Seoul using a gas/aerosol equilibrium model, called SCAPE. Particle water content and formation of solid species are closely related to ambient relative humidity and ionic concentrations. Generally, water content of particles is high during the night and summer. Estimated particle strong acidity level of Seoul is similar to that of Los Angeles, U.S.A. Acidity of wet and dry depositions in Seoul is discussed.

The concept of Hilbert space dissipative norm was introduced in [8] to obtain necessary and sufficient conditions for exponential stability of contraction semigroups. In the present paper we show that the same concept can also be used to derive further properties of contraction semigroups, as well as to characterize strongly stable semigroups that are not exponentially stable.

Purpose: The purpose of this research was to find out tobacco control education taught graduate, baccalaureate and associate degree-nursing programs in Korea. Method: A valid and reliable questionnaire previously used to assess tobacco use in medical and nursing schools in the United States was translated and revalidated. Surveys were sent out to all the graduate, baccalaureate and associate nursing programs in Korea. All 6-tobacco curricula content areas recommended by the United States National Cancer Institute and the Agency for Health Care Policy and Research was included. Result: Majority of BSN (93.2%-75%) and AD (92.3%-64.1%) programs were teaching health hazards, cancer risk, health effects of tobacco, effects of ETS, contents of cigarette, withdrawal symptoms and high risk groups of smoking as a part of required courses. However, 87.5% (14/16) of graduate, 50.0% (22/44) in baccalaureate, 53.8% (21/39) in associate degree programs were not teaching about the 5 A's. Of those who reported teaching smoking cessation strategies, they were covered most frequently in Community Nursing (50%), Adult Health Nursing (43.8%) on the graduate level, and in Community Nursing (65.9%-BSN, 76.9%-AD) and Adult Health (54.5%-BSN, 74.4%-AD) on the undergraduate level. 31.1% (5/16) in Graduate, 18.2%(8/44) in BSN, 10.3% (4/39) in Associate Degree programs reported that there are no smoking students in their schools and rest of the schools reported either do not know or they have 1 to more than 21% of students smoking. Conclusion: The study results identifies the quantity and level of tobacco control content in three different nursing programs and will help in developing curricular guidelines in the future. Further survey needs to be done on nursing students' knowledge, attitude and belief on smoking and smoking cessation.

다양한 조성의 CoFeNi합금이 chloride bath와 sulfate bath에서 전해도금 되어졌고, 합금의 도금 특성과 자기특성이 관찰되어졌다. CoFeNi합금 박막의 전해도금에 있어서 Fe조성의 증가는 chloride bath에서보다 sulfate bath에서 빠르게 증가하였다. 전류효율은 큰 변화가 보이지 않는 chloride bath와 달리 sulfate bath에서는 $750\%$에서 $50\%$로 큰 폭으로 감소하였다. Co, Fe, Ni조성이 $80\%,\;10\%,\;10\%$되는 CoFeNi합금이 이번 실험에서 가장 우수한 연자성 재료로 평가되었으며, 그때의 Coercivity는 3 Oe이고 높은 squareness값을 보였다

The objectives of this research were to identify the differences of image evaluations by perceiver's gender, majors and jeans' finishing and to examine image characteristics that have an influence on attractiveness and preferences of jeans' finishing. The subjects are 96 undergraduate students in Los Angeles of the USA. Elegant and refined images had a significant effort on perceiver's gender, so men tended to highly evaluate jeans as elegant and refined images than did women. Soft images were recognized differently by perceiver's major, so non-specialists in design tended to highly evaluate jeans as soft images than did specialists in design. In finishing, shattered wash was evaluated as the most individual, attractive, energetic, and splendid images, and stone wash was evaluated as the most ordinary, unattractive, and plain images. Light images tended to have interaction effects by majors and finishing. Specialists in design did not perceive differences between light images from finishing well, but non-specialists in design perceived that stone wash finishing's image is lighter than indigo blue finishing's image. Sociable images had interaction effects by perceiver's gender, majors and jeans' finishing, and especially non-specialists in men estimated that shattered wash has the lowest sociable images in finishing. According to evaluations about finishing images of ladies' jeans, men tended to be attracted by splendid images, and women tended to be attracted by sexy images. In addition, both men and women were commonly attracted by feminine images, so the study found that feminine images is important image for developing jeans for ladies. According to evaluations about finishing images of ladies' jeans, men preferred sexy and natural images to comfortable and energetic images, and women preferred sexy and neat images. Female undergraduate students of the USA tended to be attracted by sexy images, and we found that actually they consider buying jeans with such images.
