This study deals with the investigation of recognition structure on architectural environment and reconstruction of it by artificial intelligence. To test the possibility of the reconstruction, recognition structure on architectural environment is analysed and each steps of the structure are matched with computational methods. Edge Detection and Neural Network were selected as matching methods to each steps of recognition process. Visual perception system established by selected methods is trained and tested, and the result of the system is compared with that of experiment of human. Assuming that the artificial system resembles the process of human recognition on architectural environment, does the system give similar response of human? The result shows that it is possible to establish artificial visual perception system giving similar response with that of human when it models after the recognition structure and process of human.

This study analyzed home environment, self-efficacy and parents' child rearing attitudes of disruptive children and of cooperative children in the classroom. Participants were 322 children(11-12 years of age) and 49 teachers. Instruments were four kinds of questionnaires. Data were analyzed by T-test and Fisher's exact test. Results of between group differences in parents' academic backgrounds showed more parents of cooperative children had completed high school. Disruptive children's mothers were more occupied outside the home; cooperative children's mothers engaged in more housework at home. Disruptive children's perceptions of their economic status were lower than cooperative children's perceptions. Results of comparison of general self-efficacy, scholastic self-efficacy, and home environment showed that disruptive children were statistically lower than cooperative children on all sub-variables.

발암성 물질로 알려진 라돈($^{222}Rn$)은 원래 불활성기체로 자연계에 널리 존재하는 자연방사능으로 암석이나 토양 같은 지각물질에서 발생하는 우라늄($^{238}U$) 붕괴계열인 라듐($^{226}Ra$)의 붕괴과정에서 생성되는 방사성 가스이다. 라돈($^{222}R$)은 $\alpha$붕괴에 의하여 $^{218}Po$, $^{214}Po$등의 자핵종(Radon daughter)을 생성하며, 최종적으로 납($^{210}Pb$)으로 변한다 라돈이 폐에 흡입되면 붕괴하면서 $\alpha$방사선을 방출하는데, 이것이 인체의 세포를 죽이거나 염색체를 손상시킬 수 있으며, 폐암의 발생 위험률을 높이는 것으로 보고되었다.

지역이나 국가에 따라 사람들의 색채감성에는 조금씩 차이가 있다. 색채감성에 영향을 미치는 자연환경의 요소로는 생태조건, 기후조건, 자연광조건 등으로 나뉘며, 자연광조건은 자연광의 세기와 색온도, 생태조건은 토양과 식생, 기후조건은 온도와 습도, 쾌청지수 등으로 나눌 수 있다. 이들은 인간이 지각하는 색의 색상·명도·채도와 관련을 갖고 있다. 각 지역의 풍토조건의 차이로 생기는 색채감성의 구조를 자연광의 세기에 따른 명도 변화, 대기중의 습도에 따른 채도변화, 온도차에 따른 색상변화로 나누어 파악하였다. 또한 한국과 일본을 사례로 풍토색과 도시환경색채를 통해 색채감성의 차이를 비교하여 분석하고 그 주원인을 파악하여 지역별 색채 감성을 분석하는 기틀을 마련하고자 한다.

The purpose of this study were, (1) to analyze the effect of the selected variables on urban housewives' family resource management attitude and behavior, and (2) to identify the casual effects of variables on family resource management behavior. A sample of 641 was selected from housewives living in urban area. For data analysis, one-way ANOVA, DMR test, t-test, multiple regression, and path analysis were used. The major findings were as follows: 1. The housewives' family resource management behavior level was lower than their attitude level. 2. The family resource management attitude and behavior among the respondents were affected by the following independent variables : interest with environmental reports and newspapers, perception of time constraints, perception of economic reward. 3. The family resource management attitude had the greatest causal effect on the family resource management behavior.

For this study of the writing performance of verbally gifted elementary and middle school students and its relations to home literary environment, reading attitude, perceived verbal ability, and preference for verbal expression, a sample of 101 verbally gifted children was recruited from classes in a gifted education institute in P metropolitan area. Results of path analyses show that verbally gifted children's home literary environment affects reading attitude and perceived verbal ability; reading attitude and perceived verbal ability affects preference for verbal expression; and preference for verbal expression directly affects writing performance. Results imply that the indirect relations of home literary environment to verbally gifted children's writing performance are an important foundation for developing preference for verbal expression and writing skills.

The Foreign Language Classroom Anxiety Scale(Horwitz et al., 1986) and the Classroom Environment Scale(Moos & Tricket, 1974) were administered to 434 middle school students in Daegu. Data were analyzed by Cronbach's $\alpha$, t-test, and Pearson's correlation using the SPSS program. Results on anxiety showed no gender differences between male and female students but $9^{th}$ graders reported more anxiety than $7^{th}$ graders. Two of the nine classroom environment subscales showed differences between perceptions of male and female students, and there were significant differences between $7^{th}$ and $9^{th}$ graders. Foreign language anxiety was correlated with perceived classroom environment. This finding suggests the importance of the psychological environment between the English teacher and students for successful language education.

대금굴은 3년여 동안 암석 틈새를 들춰내며 150m쯤 물길을 찾아 들어가, 다시 18m의 수직동굴로 하강하여 좁은 틈새를 비집고 70m를 들어가는 악전고투의 탐사 끝에 2003년 동굴을 발견했다. 이렇게 3년여 동안 발굴된 대금굴은 또다시 4년여 동안의 모노레일 설치와 동굴내부 관람로 및 조명설치 등의 공사를 거쳐 2097년 6월 5일 일반 공개를 하였다. 총 길이 610m 중 4분의 3정도는 동굴 입구로 향하는 산길이고 나머지는 동굴 안쪽 길이다. 승강장에서 동굴 내부 140m에 설치된 "대금역"까지는 약 7분이 걸린다. 운전석이 없고 자동으로 운행하기 때문에 앞뒤로 동굴 안팎이 잘 보인다. 동굴 내부에 열차를 타고 들어가는 건 분명 이색체험이다. 그러나 모노레일 내부에 울리는 비발디의 "사계"라든지 동굴 벽에 붙여 놓은, 네온 빛에 가까운 퍼런 빛깔의 조명이 조용한 동굴 감상에 역효과가 초래될 수도 있다.

The housing environment improvement of the middle size cities is getting emphasized due to the decentralization. But, the way to improve the housing environment should be in progress without any consideration for citizen's lives or their own culture. Especially, in rural village, government has continually made political supports but extremely skeptical about the result, that is, they made improvement on living environment but failure in the living quality. This institute intends to find out cultural elements of traditional architecture are. Tradition has to make effects on the present age. It has to have great influence on the entire housing environment in addition to each architecture.

다양한 특성들을 가지고 있는 멀티에이전트 시스템의 행동학습은 에이전트 설계에 많은 부담을 덜어준다. 특성들로부터 나오는 다양한 행동의 효과적인 학습은 에이전트들이 환경에 대한 자율성과 반응성을 높여준 수 있다. 행동학습은 model-based learning과 같은 교사학습보다는 각 상태를 바로 지각하여 학습하는 강화학습과 같은 비교사 학습이 효과적이다. 본 논문은 로봇축구환경에 에이전트들의 행동을 개선된 강화학습법인 Modular Q-learning을 적용하여 복잡한 상태공간을 효과적으로 나누어 에이전트들의 자율성과 반응성을 높일 수 있는 강화학습구조를 제안한다.
