대도시의 인구 집중화 현상에 의해 1970년대부터 다수의 조적조 건축물이 시공되었으며, 존치 기간의 증가에 따라 그 구조 성능의 저하가 진행되고 있다. 이들은 현재 노후화가 진전되어 이에 대한 관리와 체계적 정비 계획이 필요한 시점에 이르렀다. 따라서, 우리나라 대표적 대도시인 서울시를 중심으로 20년 이상된 노후 조적조 건축물의 현황 및 노후화 정도, 요인별 상관관계를 정리 분석하고, 효율적인 관리와 체계적인 대책 수립에 기본 자료를 제시하고자 한다. 본 연구는 서울시를 중심으로 한 건축물들의 분포 특성과 구조적 열화성상, 그리고 상관관계를 검토하였다. 본 연구를 통해 조적조 건축물은 기초에 많은 문제를 가지고 있고 열화에 미치는 가장 큰 요인은 균열로 분석되었고, 건물유형별로는 상가가 가장 취약한 구조형식을 가지고 있는 것으로 나타났다.

Objectives: The purpose of this experiment is to better understand the nitrogen and phosphorus removal ratio according to operating conditions in an iron electrolysis system consisting of an anoxic basin, aerobic basin, and iron precipitation apparatus. Methods: Iron electrolysis consists of an iron precipitation reactor composed of iron plates in oxic and anoxic basins. We studied the interrelation coefficient between T-N and T-P removal rates and F/M ratio, and the C/N ratio and BOD removal rate. Results: The F/M ratio and the T-N and T-P removal rate per unit area have interrelation coefficients of 0.362 and 0.603, respectively. The removal rate per MLVSS and the T-N and T-P removal rate per unit area have respective interrelation coefficients of 0.49 and 0.59. Conclusions: The removal rate of T-N and T-P increased with the increasing F/M ratio in the influent, and they also linearly increased in proportion to the C/N ratio of influent and BOD removal rate of the reactor.

To study the sexual maturity at puberty and interrelation between pubertal growth peak and sexual maturity, 68 malocclusions (female 44, male 24) were longitudinally studied for 4 years and cross-sectional samples of 210 malocclusions were studied together. The pubertal growth peak was determined by stature increment and sexual maturity was studied using developmental stages of pubic hair and breast, menarche in female and those of pubic hair in male. The following results were obtained. 1. Mean age at menarche was 12.8 years and it was 11.8 months later than PHV. 2. At pubertal growth peak, developmental stage 2 (54.2%) and 3 (29.2%) of pubic hair were most in male, and stage 1 (72.7%) and 2 (20.5%) were most in female. 3. At pubertal growth peak, the developmental stage 2 (50%) of breast was most and the stage 3 (43.2%) was next. 4. In interrelation between skeletal growth and sexual maturity, PHV had most high correlation with menarche and stage 3 of breast, and menarche had most high correlation with stage 3 of breast. 5. Appearance of remarkable sexual maturity suggested that the PHV was passed already.

The purpose of this study is to understand the current status of high school students' exposure to pornographic materials as well as to provide basic data to develop sex education programs. This study was conducted through a self-administered questionnaire survey of 774 students of six high schools in Seoul, three boys' and three girls' respectively, from August 22 to August 25, 2000. This study shows that high school students' exposure to pornographic materials such as CD-ROMs, internet, video tapes and adult movies has become very serious. The results of this study are as follows. 1. Among the students surveyed, $23.5\%$ of them currently has opposite-sex friends, while $42.2\%$ used to have and $34.2\%$ has never had opposite-sex friends. 2. $55.3\%$ of the students pick up their sexual knowledge from their friends, followed by mass media $(47.5\%),\;school (21.1\%),\;adult\; magazines (17.1\%)\;, internet (14.1\%)$, pornography visual $materials (11.5\%),\; sexual\; books (3.6\%)$ and pornography printed $materials (2.4\%).$ 3. Regarding the frequency of sexual education taken in school, $54.2\%$ of the students answered 'often', while $37.6\%$ answered 'almost none', 'several times' $(4.4\%)$, 'never' $(2.9\%)$ and 'frequently' $(0.9\%)$, respectively. Regarding sexual education at home, $42.2\%$ answered 'almost none', followed by 'never' $(36.3\%)$, 'often' $(16.3\%)$, 'several times' $(3.3\%)$ and 'frequently' $(1.8\%)$, respectively. 4. $68.2\%$ of the students have been exposed to adult movies, followed by pornography videos $(60.1\%)$, internet chatting $(50.2\%)$ and pornography computer diskettes $(38.0\%)$. 5. The degree of exposure to pornographic materials of boy students is much higher than that of girl students. 6. It appears that there is an interrelation between the kind of schools and the degree of the students' exposure to pornographic materials. 7. The higher the students' grade is. the more they have been exposed to pornographic materials. 8. It shows that there is an interrelation between the students' academic performance and the degree of their exposure to pornographic materials. 9. There is also an interrelation between the amount of students' pocket money and the degree of their exposure to pornographic materials. 10. There is an interrelation between the degree of their adaptation to school life and the degree of their exposure to pornographic materials. 11. It appears that there is an interrelation between their parents' relations with them and the degree of the students' exposure to pornographic materials. 12. There is a significant difference in the degree of their exposure to pornographic materials in accordance with their residential area. 13. There is also a significant difference in the degree of their exposure to pornographic materials in accordance with the average income of their families. 14. There is also a significant difference in the degree of their exposure to pornographic materials in accordance with the mean sexual education at home.

Modern interior design is expanding diversely, with the rapid development of technology and change of era. The basic of interior space that is rapidly changing consists of floor, wall and ceiling, and these are formed by materials, materials for structure or finishing materials. In the modern interior space, materials are utilized to present an atmosphere that meets the trend of the dissolution of post-modernism and the trend of minimalism. Accordingly, in this study, designers who take serious view on the relation of space and material, and the relation focusing on completed works, in modern interior design were investigated. The interrelation of the representation of each material, organic space, minimal space, and the space of Oriental fusion style were investigated through the works of modern interior designers, such as Karim Rashid and Ettore Sottsass.

The purpose of this study was to get a possibility of maintenance architecture, which present instead of contemporary architecture through interrelation between Organic architecture and Gaia theory. Through this study to fine a interrelation part between Organic architecture and Gaia Theory as general case, and through the Gaia theory, Organic architecture being progress as new design experiment exposition. After modern time, we can have presentation of main subject which corresponds to mechanical rationalism and rising Organic architecture from Organic Holism. Organic architecture is get close to biological or ecological access to nature and environment so from and inner order could apply to architecture after that better circumstances and maintenance(sustain architecture) development could possible, although the point became more importance. In this point, Jim E. Lovelock's Gagia theory which try to proscript relationship(element of enviroment) of earth, this is pretty big deal and we can find a connection with Organic architecture in the theory.
