The objectives of study were 1) to investigate the motives for moving to the current residence, 2) to analyze residential satisfaction after moving in relation to household characteristics and the motives for moving, and 3) to test relationships among household characteristics, residential satisfaction before moving, motives for moving, and residential satisfaction after moving. Residential satisfaction was evaluated in relation to housing, neighborhood, and socio-psychological environments. Methdo-logy included literature and questionnaire survey. Questionnaires were administered to 269 homemakers living in an apartment complex in seoul. Data were analyzed with the use of SPSSS PC+ computer package. The motives for moving were classified in five types: tenureship improvement, improvement of the physical condition of housing, improvement of neighborhood environment, commuting improvement, and constraints. There were significant differences in the types of motives for moving by socio-economic status, types of houses lived in previously, change in type of tenures, and the duration of residence before moving. There were significant differences in residential satisfaction after moving among types of houses lived in previously, change in type of tenures, and the types of the motives for moving. There were significant relationships among residential satisfaction variables. They were the socio-economic status, change in type of tenures, residential satisfaction before moving.

Based on residents' survey data in Seoul, this study attempts to empirically answer to four research questions regarding neighborhood relations (NR) which are necessary for community building: How important NR is compared to other social relations, what factors establish NR, how large NR's geographical extent is, and what are major meeting places among neighbors. A series of statistical analyses demonstrates that characteristics of NR vary greatly by family life cycle. In the stage of couple without child, NR has no significant meaning. NR becomes important from the stage of child care, and it is formed through the medium of children, particularly children's schools in the stage of child of elementary school as well as secondary schools. As the result, NR's geographical boundary extends beyond residential block or multi-family housing (apartment) estate while cafe and restaurant serve as dominant meeting places in these life cycle stages. On the contrary, after children are married and leave home, casual encounters resulted from spatial proximity become an important cause of NR. Likewise neighbors' geographical distribution is relatively concentrated within residential block or apartment estate, while community facilities play a role of meeting places as originally planned and designed.

The purpose of this study was to investigate the correlations between the school neighorhood environment and adolescents’behaviors. A questionnare was distributed to 221 high school students from June 27. 1997 t해 July 16. 1997 in chonju. In this study SAS package was used. The statistical methods such as frequency. mean. analysis of variance. correlation analysis. multiple regression analysis and T-Test were applied. The result of this study were as follows. 1) The school neighborhood environment of B high school included much more problematic places than A high school in 20 minutes distance on foot. So B high school students visited problematic places more frequently than A high school students(p<.05). 2) Both of A high school students and B high school students didn’t be satisfied about the school neighborhood environment. The degree of satisfaction for school environment of A high school student was higher than that of B. (p<.001) The number of benefit facilities. the degree of cleanness, and the safety from automobiles positively influenced the satisfaction for school neighbor environment. while the number and visiting of harm facilities negatively in satisfaction. 3)The problematic behaviors of B high school students was higher than A high school students(p<.05)

Low-rise Residential neighborhoods of Hongdae area, Garosu-gil, Samchung-dong, Itawon etc. are currently emerging new spaces for cultural consumption in the city. Nonetheless undiscerning excessive commercialization often results in monotonous urban space and deportation of residents and leaders of change; Due to commercialization and popularization recently this phenomenon is influencing surrounding low-rise residential neighborhoods. The main objective of this study is to examine how surrounding low-rise residential neighborhood transforms according to the expansion of culture-commerce spaces. Hongdae area's culture-commerce spaces and its expansion into Yeonnam-dong is investigated in specific. Especially attributes and main causes of transformation in physical and experiential space of neighborhood living facilities and residential buildings, when changed into culture-commerce related use is examined in detail. The expansion of culture-commerce space of Hongdae to Yeonnam-dong area has positive meaning in aspects of everyday experience. First, physical alteration of street-building relation increases direct and indirect contact of people. Contact opportunity carries important meaning in sense that it is prerequisite for next stage contact of network and exchange. Second, culture-commerce related programs provide the third place, where various leisure activities can take place. Attributes of transformation and positive meaning of culture-commerce spaces expanding its territory presents the need of management.

The objective of the study is 10 know the relation of landslide occurrence with using TPI (Topographic Position Index) in the Pyungchang County. Total 659 landslide scars were detected from aerial photographs. To analyze TPI, 100m SN (Small-Neighborhood) TPI map, 500m LN (Large-Neighborhood) TPI map, and slope map were generated from the DEM (Digital Elevation Model) data which are made from 1 : 5,000 digital topographic map. 10 classes clustered by regular condition after overlapping each TPI maps and slope map. Through this process, we could make landform classification map. Because it is only to classify landform, 7 classes were finally regrouped by the slope angle information of landslide occurrence detected from aerial photography analysis. The accuracy of reclassified map is about 46%.

The Ecological variables studied in relation to children's school adjustment were organisms(grade, sex, perceived competence, aggression and withdrawal), microsystems(parental support, marital conflict and supervision, peer victimization and perceived teacher attitude), mesosystems(family-peer relationships, family-school relationships) and the exosystem(neighborhood environment). The sample consisted of 565 fifth and sixth grade children. Instruments were the School Adjustment Scale and Index of organisms, microsystems, mesosystems, and exosystem variables. Statistics and methods used for the data analysis were Cronbach's alpha, frequency, percentage, Pearson's correlation and multiple regression. Several major results were found from the analysis. First, children's school adjustment showed positive correlations with perceived competence, parental support and supervision, perceived teacher attitude, family/peer and family/school relationships and neighborhood environment but showed negative correlations with grade, aggression, withdrawal and parental marital conflict and peer victimization. Second, the most important variable predicting child's relationship with teacher, his/her academic adjustment and satisfaction in schoolwas perceived teacher attitude. And the most important variable predicting children's peer relationships in school was perceived social competence.

Cellular automata are discrete dynamical systems whose behaviour is completely specified in terms of a local relation. If cellular automata convergence to fixed points, then it can be used to image processing. From the generalized Potts automata point of view, we propose in this paper a cellular automata technique for reducing image noise. To minimize blurring effect, an algorithm based on neighborhood median computation is Preferred. Experimental results are reported.

A method to design a robust servomechanism by continuously variable structure control is proposed. The state and control signal of this servomechanism do notchatter since a continuous control scheme is used. The input-output relation of this servomechanism is determined by prescribing a hyperplane in a state space of which the neighborhood is asymptotically attractive everywhere. This control mechanism was applied to a single rod cylinder servomechanism which has the nonlinerities due to their nonsymmetrical structure and its excellency was verified.

The ages of field stars given in the catalogue of Cayrel de Strobel et al. (1985) are derived by the five different methods with combination of theoretical isochrones. By using these ages and metal abundances homogenized by Lee and Choe (1988), the age-metallicity relations are obtained. For disk stars of [Fe/H] > -0.9, the present age-metallicity relations are nearly consistent with those given by Twarog (1980) and Carlberg et al. (1985).

본 논문에서는 칼라공간상의 거리와 이웃정보를 이용한 클러스터링을 통한 칼라영상 분할 방법을 제안한다. 영상의 픽셀들을 이웃관계를 유지하여 칼라공간으로 매핑한다. 칼라공간상에서 이웃하는 픽셀들을 클러스터링하여 영상의 세그먼트들을 찾는다. 클러스터링 방법으로서 인력을 모방하는 클러스터링(gravitational clustering)을 사용하였다. 이 방법으로 클러스터의 중심값과 클러스터 수를 미리 정해주지 않아도 자동적으로 결정할 수 있는 장점이 있다. gravitational 클러스터링에서 찾은 클러스터 수를 가지고 다른 클러스터링 방법에 입력으로 주어 결과를 비교해 본다. 본 논문에서는 이웃관계를 따라 클러스터링하는 것이 정확한 경계선을 찾는데 효과적임을 보여준다.
