The present study is a preliminary research improving the dwelling quality of apartment house as a kind of multi-family housing. The purpose of the study is to find out the actual state on characteristics of indoor noise including residents' living in apartment units. The method was field survey consisted of field measurements on equivalent noise level, observation on noise type, and interview on residents' responses. Field survey were carried out in 20 occupied apartment units from January to March 2007. The results are as follows. 1) Averages of indoor noise levels including residents' living noise were measured as $43.9{\sim}62.2\;dB(A)_{Leq5min}$, the average of each house except one was higher than the permissible level, 45 dB(A). 2) The noise types observed were mostly residents' living noise and classified into 'water hammer', 'living equipment noise', 'noise by family', 'hood noise', 'kitchen noise' in own unit, 'walking and talking noise in stairs and corridors', 'noise by neighborhood house', 'noise by the upper story' in building, and outdoor noise. 3) The residents showed slightly non-positive responses at 'noise by the upper story', 'noise by neighborhood house', 'water hammer', and 'noise by family'. Therefore, it is required to plan for preventing deterioration of the dwelling quality by residents' living noise in own unit as well as by neighborhood houses.

Korea is experiencing unprecedented destruction of communities and crisis of mental health represented by top suicide rate among OECD countries. Its causes are manifold of various factors. One of them is lack of social support and broken communities that are closely related to social capital that is linked to other health indicators such as mortality rates. This studies looks for ways to improve social capital through spatial structure and features especially social capital related to neighborhood. Researchers conducted research literature review and observation on physical features of neighborhood streets and alleys. Review of studies show housing types can affect social capital level. High-rise apartments are related with lower neighborhood related social capital compared to single homes and low-rise multi-housing. Studies that mainly examined the physical features such as street layout showed that social encounters happened around local stores and crossings of small roads. Researchers identified actual streets that are more likely to be related with social activities in the neighborhood. Those streets were with physical elements that helped social exchange such as narrower streets, exposed stairs, street furniture of residents, parks, crossing of streets while other streets were with wider and easier access of cars.

This study intended to investigate the relationship between father's/mother's values(materialism, competitive achievement pressure, neighborhood relations), father/mother-student emotional intimacy & father's/mother's over control and university student's alienation, and examin the relative influences of independent variables on university student's alienation. For this purpose, data were obtained from 402 male 7nd female university students in Seoul and Inchon, and analyzed by factor analysis, Cronbach's $\alpha$, frequencies, %, Pearson's r and stepwise multiple regression. The major findings were as follows : 1) father's and mother's values had significant relations to university student's alienation. As father and mother had more materialism and competitive achievement pressure, their university student was more alienated, and as father and mother had more neighborhood relations, the student was less alienated. 2) Emotional intimacy between father/mother and student had negative relation to university student's alienation. As the level of emotional intimacy was higher, the student was less alienated 3) Father's and mother's over control had positive relations to university student's alienation. As father's and mother's over control was higher, the student was more alienated. 4) Mother's neighborhood relations, father's and mother's over control, mother-student emotional intimacy and father's materialism had influences on university student's alienation in descending order. These independent variables explained 25. 0 % of the total valiance. Father's materialism and father's/mother's over control increased the level of university student's alienation, but mother's neighborhood relations and mother-student emotional intimacy decreased the bevel of student's alienation. Emerging evidences suggested that in order to prevent or decrease the university student's alienation, their parents should have less materialism and more neighborhood relations, and should not use over control on their university student but produce more emotional support.

본 연구는 건강을 설명하는 지역 박탈 지표를 선별하고 이러한 지표들이 근린사회의 인구구성효과와 구분되는 독립적인 맥락효과를 지니는지 검증해 보았다. 이를 위하여 서울시를 대상으로 행정동 단위의 표준화사망비를 산출하여 소지역 건강불평등 실태를 분석하였고, 표준화사망비 격차를 설명하는 지역박탈 지표들을 선정하였다. 그리고 다수 준 모형을 통해 개인의 사회경제적 지위를 통제한 후 지역박탈 효과를 검증하였다. 분석 결과는 건강불평등의 지역 격차가 대부분 사회경제적 지위 요인을 반영할 뿐이며, 거주지 지역사회의 독립된 맥락효과는 미미한 것으로 나타났다. 분석에서 행정동별 표준화사망비 분포가 취약근린지수의 분포와 유사하고 더 나아가 공시지가, 하위교육수준, 복지수급자 비율, 여성가구주 가구의 개별 지표 분포와 유사한 패턴을 보이고 있는 것으로 나타나 전반적으로 인구집단의 취약성을 반영하는 것으로 보인다. 반면 빈곤 지역이 내생적으로 형성하는 건강문화나 보건의료접근성 등의 가능한 매개 요인들의 가능성은 인구 구성에 따른 빈곤과 결핍보다 상대적으로 저조할 것으로 보인다. 즉 건강의 지역별 격차는 다름 아닌 계층간 격차로 해석될 수 있다.

Korea's transportation paradigm is shifting from a vehicle-oriented transportation plan to a pedestrian-friendly environment that emphasizes walking safety. However, the level of pedestrian traffic accidents in Korea is still high and serious. The purpose of this study is to investigate factors affecting the severity of pedestrians traffic accidents using the multilevel logistic regression model based on 2015-2017 pedestrian accidents data provided by the Traffic Accident Analysis System(TAAS). The main results of the multilevel logistic regression model showed that 89% of pedestrian traffic accidents in Seoul were explained by individual characteristics such as drivers and pedestrians, and 11% were explained by neighborhood environmental characteristics. The results are as follows : In the individual characteristics such as pedestrians and drivers, the older the pedestrians and the drivers, the higher the traffic accident severity. The severity of traffic accidents was high when the pedestrians were female and the drivers were male. In the case of accident types, traffic accidents were more serious in the cases of heavy vehicles, inclement weather, and occurring at intersections and crosswalks. The results of the neighborhood environmental characteristics are as follows. The intersection density and the crosswalk density tended to reduce the severity of traffic accidents. On the other hand, the traffic light density and the school zones were founded to related to the higher level of traffic accident severity. This study suggests that both individual and neighborhood environmental characteristics should be considered together to prevent and reduce the severity of pedestrian traffic accidents.

Objectives: The purpose of this study is to examine change in adolescent depression across time and to determine the relation between individual and neighborhood socioeconomic status (SES) and depression. Methods: This study employed multilevel latent growth analysis using longitudinal data from Korea Children and Youth Panel Survey. A sample of this study consists of 2,351 adolescents who were in first grade of middle school in 2010. Results: Results showed that both initial level and downward trajectory of depression varied significantly across individuals as well as across neighborhoods. On the individual level, self-rated economic condition(b=-0.203, p<.001) was related to the initial level of depression. Adolescents whose father had a high educational level(b=0.028, p<.001) or whose mother had a low educational level(b=-0.022, p=.011) had lower rates of decline in adolescent depression. On the neighborhood level, neighborhood deprivation index (b=0.003, p=.019) and gini coefficient(b=0.124, p=.040) were associated with lower rates of decline in depression. Conclusions: Low SES in adolescence is correlated with worse mental health, especially depression. Social disparities in depression likely originate before adulthood. The findings argue for the importance of understanding depression in adolescence from a multilevel or ecological framework.

Objectives: We examined whether the neighborhood socioeconomic position predicts the smoking rates after adjusting for individual socioeconomic position indicators. Methods: Data were obtained from the 2001 Seoul Health Indicators Survey. The neighborhood socioeconomic position was the residential distribution of the high class (power elites), as measured by the location quotients (LQ) for each administrative dong (district). A high LQ denotes a high neighborhood socioeconomic status. The individual socioeconomic position included education, occupation and income. Age-adjusted smoking rates according to the LQ level were computed with the direct method. The total number of subjects in this study (26,022 men and 28,007 women) was the reference. A multilevel logistic regression analysis was conducted with the individuals at the first level and the neighborhoods at the second level to estimate the odds ratios of smoking with 95% confidence intervals. Results: For men, the age-adjusted smoking rates increased with a decrease in the LQ. For women, the relationship between the age-adjusted smoking rate and the LQ was not clear. The odds of smoking for both genders were greater among those subjects with lower incomes and lower education. The manual occupational class had greater odds of smoking than the non-manual class for the males, while the odds ratio of smoking among females with a manual occupation tended to be lower than those females with a non-manual occupation. For the males, the LQ levels independently predicted smoking after adjustment for individual income. However, this relation between the LQ and smoking in males was explained by full adjustment for the individual socioeconomic position indicators (education, occupation and income). Conclusions: A low level of neighborhood socioeconomic position was associated with higher smoking rates among the men residing in Seoul. This association between the neighborhood socioeconomic position and smoking in men was explained by the individual socioeconomic position. Anti-smoking efforts to reduce geographical inequality in smoking should be directed at reducing the smoking rates between the individuals with different socioeconomic backgrounds in the metropolitan city of Seoul, South Korea.

In this paper, we propose a new approach to learning a discriminative model for figure/ground segmentation by incorporating the bag-of-features and conditional random field (CRF) techniques. We advocate the use of image patches instead of superpixels as the basic processing unit. The latter has a homogeneous appearance and adheres to object boundaries, while an image patch often contains more discriminative information (e.g., local image structure) to distinguish its categories. We use pixel-level sparse coding to represent an image patch. With the proposed feature representation, the unary classifier achieves a considerable binary segmentation performance. Further, we integrate unary and pairwise potentials into the CRF model to refine the segmentation results. The pairwise potentials include color and texture potentials with neighborhood interactions, and an edge potential. High segmentation accuracy is demonstrated on three benchmark datasets: the Weizmann horse dataset, the VOC2006 cow dataset, and the MSRC multiclass dataset. Extensive experiments show that the proposed approach performs favorably against the state-of-the-art approaches.
