Angus postweaning daily gain (PWDG) were analyzed to investigate heterogeneous variance by sex. A set of data (16,239 records) was divided into six sub-data sets according to level of environment. REML estimation was conducted by a multitrait model, where PWDG in each sex was treated as a separate trait. Estimates showed diversity among environmental levels, where the heritability for heifers was high in good environment but low in poor environment. The bull's estimates varied among environmental levels. The largest heterogeneity of phenotypic variance between sexes was estimated in a data set of the poor environment level. The genetic correlations between the heifer's PWDG and the bull's PWDG were high in the good environment and low in the poor environment (-0.17). The results suggest existence of genotype by sex interaction in the poor environment.

With regard to Jeju Special Self-governing Province's natural-spa tourist spot development project, this paper has investigated the natural environment of Sehwa-Songdang Lave Region. According to this study, the cave consists of many small caverns with poor cave formations. Due to unfavorable climate conditions in the cave, in addition, hydrological environment is also very poor. In terms of vegetation, the cave shows the general vegetation environment of Jeju.

교통 표지판 인식(TSR)은 운전자 보조 시스템(ADAS)의 중요한 부분 중의 하나이다. 하지만 일반적인 주간 상황이 아닌 야간, 눈, 비, 안개 등의 열악한 상황에 대한 연구는 주간 상황과 달리 표지판 고유의 색이 정확히 나타나지 않기 때문에 많이 이루어지지 않고 있다. 본 논문에서는, 주간 상황뿐 아니라 열악한 환경에서도 적용 가능한 기계학습 기반의 교통 표지판 인식 알고리즘을 제안한다. 열악한 환경에서는 일반적인 RGB 색 체계 정보를 이용한 방법은 좋은 성능을 보이지 못하므로 표지판의 형태적 특징을 이용하는 HoG 특징점 추출기를 이용하여 표지판의 형태적 특징을 추출하고 SVM 알고리즘을 이용하여 표지판을 검출하였다. 검출한 표지판의 인식에는 Normalized RGB 색 체계의 25개의 참조점을 통한 의사결정트리를 이용하였다. Intel i5 3.4GHz 환경에서 Full HD 해상도의 이미지에 대해 실험한 결과 안개 및 야간 등의 열악한 환경에서의 검출률은 96.4%, 인식률은 94%로 본 논문에서 제안하는 학습기반의 알고리즘이 열악한 환경에서의 표지판 검출 및 인식에 효율적으로 적용이 가능함을 알 수 있다.

The objective of this study is to analyse consumption problems of the rural poor households. This is a succeeding work to the previous report on economic resource problems. Data from 154 rural poor house holds and 290 rural non-poor households were analysed to comprehend their consumption practices, financial management ability, consumer competence of homemakers, and market environments. The major findings and conclusions are as follows : 1. The rural poor households had deficit of 30, 000 won per month. They perceived relative importance of the educational expenses and food expenses and heavier pressure of educational expenses and light and water expenses than other items. 2. The rural poor households evaluated their financial management ability average like non-poor households but their level of consumer competence was lower than other households. This means their consumer efficiency is relatively low. 3. The rural poor households had similar grade of market environments to non-poor households. This is significantly different from urban households.

Purpose: Few studies have considered the psychosocial work environment factors in relation to employee health. This study explored the relationship between psychosocial work characteristics and self-rated health among Korean employees. Methods: The study population of 21,476 employees was derived from the 2014 Korean Work Environment Survey (KWES). Psychosocial work environment was measured by Copenhagen psychosocial questionnaire scales. Results: Among employees at workplaces (n=21,476), 23.3% rated their health as poor. Among 12 indicators of psychosocial work environment characteristics, 'higher emotional demand', 'demands for hiding emotions', 'work-family conflict', and 'social community at work' were independently associated with risk of poor self-rated health of Korean employees after adjustment of all sociodemographics, work condition characteristics and physical work environment exposure. In addition, higher 'possibilities for development' and 'social support from supervisor' were more likely to decrease the risk of poor health. Conclusion: We suggest that psychosocial work environment is an important determinant of employees' health. The study results provide a good starting point for developing intervention and strategies for health improvement.

The Purpose of this study was to identify factors that influence the self-esteem of the schooler of families in poverty. A descriptive, correlational, and cross-sectional study design was used. The data were collected from February to March, 2001. Convenient sampling was done from 194 subjects living in Jeju Do, but 167 subjects among these were used for the study analysis. Hierarchical Stepwise Regression was used to identify significant factors. The results of this study were as follows: In general, self-esteem status of the schooler in poor families was relatively poor. In stepwise regression analysis, self-esteem status was significantly influenced by emotional home environment, duration of poverty and frequency of parent-child tactics. These variables explained 26.8％ of the variance of schooler's self-esteem. Conclusively, it is recommended that nursing intervention programs for schooler in poor family should be a focus to enhance the economic context as well as family effect.

본 연구는 국가공간정보포털에서 제공하는 국토정보들을 활용하여 빈곤 취약지구를 추출하는 방법론을 정립하는데 목적을 두었다. 빈곤 취약지구를 추출하기 위한 지표들을 선정하고 지표들의 작동성을 검정하였으며, 특히 빈곤 취약지구를 추출하는 위계적인 공간 영역에 따라 지표들의 활용이 조정 가능하도록 융통성있는 방법론을 구축하는데 초점을 두었다. 빈곤 취약지구를 추출하기 위한 지표들을 빈곤층, 노후불량주택, 근린불량주거환경의 세 영역으로 분류하고 각각의 영역에 적합한 대표 지표들을 선정하였다. 그 결과 행정동 차원에서 빈곤 취약지구 추출을 위한 핵심 지표는 천명당 기초생활수급자수와 노후단독주택 거주 가구 비율 지표로 나타났다. 국가기초구역 차원에서 근린불량주거환경을 나타내는 지표로는 불량도로 접도 주택비율, 과소필지 비율, 노후불량주택 비율이 상당히 중요한 지표로 나타났다. 본 연구에서는 소구역 단위에서 격자 분석을 통해 여러 지표들을 중첩시켜본 결과 상대적으로 더 빈곤하고 취약한 소구역을 추출할 수 있었다. 국가공간정보포탈에서 제공하는 데이터를 필요한 목적에 맞추어 활용하는 경우 고부가가치의 정보 창출 가능성을 보여주었다는 점에서 본 연구의 학술적 의의를 찾을 수 있다. 본 연구의 방법론은 빈곤 취약 우선 대상지구를 효율적으로 선정하는데 도움을 줄 수 있을 것이다.

This study identified the rate of income poverty and multidimensional poverty, correlation between income poverty and multidimensional poverty, and adjusted multidimensional poverty rate. We also analyzed the factors that affected the number of poverty dimension and the probability of belonging to the poor or not in 3,159 elderly households including 474 poor households and 2,685 middle class households. First, in poor households, the employment poverty rate was the highest and the housing poverty rate was the lowest. In middle class households, the relation poverty rate was the highest and the employment poverty rate was the lowest. Second, in poor households, correlation between asset poverty and relation poverty had the highest coefficient of .205 and asset poverty and housing poverty had the lowest coefficient of .149. In middle class households, the correlation between income poverty and relation poverty had highest coefficient of -.290 and employment poverty and relation poverty had the lowest coefficient of .038. Third, in poor households, the number of average poverty dimension was 4.30, but the number of average poverty dimensions of middle class households was 2.310. Fourth, the variable affecting the number of poverty dimensions in poor households were gender, age, level of education, marital status; however, the significant variables were gender, education level, marital status, income poverty in the middle class households. The variable that affected the probability of belonging to the poor or not in poor households was age. However, the significant variables were gender, education level, marital status, residence, and income poverty in middle class households.

Purpose: The aim of this study is to provide baseline data on the housing environment of a vulnerable population. Methods: This study provides a descriptive survey on the housing environment of a vulnerable population of a city in Gyeong-gi province. A total of 9,061 households were selected as research participants. Data were collected through face-to-face interviews by visiting nurses from February 2014 to March 2014. Results: Interviewees answered "poor" on items including cold drafts, illumination, daylight penetration, inflow of polluted air, house odor, stairs safety, noise, mold, pests, and ventilation. The score for housing environment problems showed a significant group difference due to gender, age, economic status, family type, type of housing, and type of ownership. Conclusion: These results indicate that the vulnerable population is exposed to a poor housing environment. Thus, there is an urgent need to improve the housing environment for the vulnerable population. Based on this study, linking a visiting health care service program and housing environment improvement projects from relevant administrative agencies might be recommended in order to effectively improve the housing environment.
