Objective: Despite known associations between negative body image and health declines in chronic pain patients, few studies have examined longitudinal associations between psychological stress and perceived hand deformities. This study examined whether psychological distress was associated with hand deformities 4 years later and if rural and urban adults differed in the association. Design: A community-based cohort study. Methods: Community dwelling adults (mean age=51.97, 52.3% women) in a rural (n=2968) and urban area (n=2784) provided demographic data at baseline and, in the 4-year follow-up, responded to questionnaires about psychological distress. Perceived hand deformities were assessed at the 8-year follow-up. Linear regression was conducted to examine the effects of psychological distress on hand deformities and moderation by residential areas. Results: The perceived hand deformities were more likely among those with severe psychological stress, hand osteoarthritis, or any chronic disease condition (p<0.01) but less likely among those with younger age, higher education, or income (p<0.01). The regression results showed that psychological distress predicted more perceived hand deformities 4 years later even after adjusting for demographic and health covariates (p<0.01). The residential areas did not significantly moderate the association between distress and hand deformities. Conclusions: This study suggected that psychological distress may trigger later perception of hand deformities in both urband and rural adults. The findings indicate that stress management interventions that are customizable to regional contexts may be effective at preventing negative body image related health problems of community-dewelling adults.

This study was conducted to measure the diurnal variation and behaviour of atmospheric mercury in an urban area by gold amalgamation and cold vapour atomic absorption spectrophotometry. The results were as follows: 1. The Hg concentration in ambient air averaged. 21.13ng/m$^3$ for 111 determinations (C.V. 78.5) in urban area and 5.91ng/m$^3$ for 140 determinations (C.V. 21.3) in suburban area. The urban area concentration was significantly higher and fluctuated more than its rural counterpart. 2. Regression analysis of the interaction between mercury concentration and other components showed a significant correlation between mercury concentration and sulfur dioxide also, TSP were found. Mercury concentration was shown to have a similar behaviour, on the whole, with other air pollutants. 3. It demonstrated a positive correlation with sunlight (UV-ray), while it had a negative response to wind speed and humidity. Its concentration showed a tendensy to increase during calm weather specifically. 4. The Hg concentration at the Mt. Dok You inland clean area ranged from 1.33ng/m$^3$ to 2.0ng/m$^3$, with a mean value of 1.63ng/m$^3$.

본 연구에서는 초등학교 3, 4, 5학년 학생들을 대상으로 학습자의 학업성적에 영향을 미치는 학습자 변인 중 성차 그리고 환경 변인 중 거주지역에 따른 수학교과 학업성적의 차를 분석하였다. 그 결과, 수학교과에서 초등학교 남녀 학생들의 학업성적의 차와 성취수준별 비율의 차이에서 모두 공통된 현상을 보여주는 것으로 나타났다. 즉 초등학교 3학년에서는 여학생의 수학성적이 우위를 나타냈지만 4학년과 5학년에 와서는 이러한 현상이 점점 약화되는 것으로 분석되었다. 한편 수학 학업성적에서의 점수대별 성별 분포를 분석한 결과, 초등학교 5학년까지는 각 점수대별 남녀의 비율이 거의 유사한 현상을 보이는 것으로 나타나 학업성적 수준별 남녀 학생의 비율을 분석한 선행 연구 결과와는 일치하지 않는 현상을 보여주었다. 대도시, 중소도시, 읍면지역 초등학교 3, 4, 5학년 학생들의 수학 학업성적을 분석한 결과에서는 21세기가 한창 진행되고 있는 현대 사회에서도 도농 간 학력격차의 문제는 그대로 진행되고 있으며 더구나 읍면지역 학생들의 낮은 학업성취는 초등학교 4학년부터 본격화되는 것으로 나타났다.

The purpose of this study is to quantitatively analyze the corresponding residents' benefit to get in the future from the district unit plan of the settlement zone by Cheongju local government. The target districts were selected as Gumdeong-gol district, Juseong district, and Shinmok-gol district, and Hyeonam district which had recently set their district unit plans. Specific targets to be analyzed were some infrastructure including roads, parking lots, parks and others. Using the analysis methods of the Logit model and non-parametric test approach, this study estimated to the average amounts to be willingly paid(WTP) by the residents in targeting settlement zones and tested the reliability of the average amounts of WTP. The results of analysis were as follows. First, it was found that the WTPs for infrastructure under 1st influence area in target districts were estimated as 5,233won for road, 2,826won for parking lot, and 3,705won for park respectively. For the WTPs for infrastructure under 1nd area were estimated as 4,910 won for road, 2,242won for parking lot, and 3,620won for park respectively. Second, as the result of calculating the non-parametric WTP which built the 95% confidence interval, it was found that the all WTPs except the WTP for parking lot were fell into the 95% confidence interval. Third, as the result of calculating yearly total sum of benefits that the residents would get from the 1st influence area and the 2nd influence area, it was found that Gumdeong-gol district were expected to get 62,376,472won-amounted benefits, and Juseong district, and Shinmok-gol district, and Hyeonam district would get 35,0778,016won, 26,886,560won, and 22,252,032won respectively.

This study analyzed the types of Rural Villages, divided the areas with six criteria such as geographical environment and selected three target areas to observe them. Through these target areas, it attempted to analyze the difference and correlation of satisfaction with the residential environment depending on the characteristics of the Rural Village. In investigating and analyzing the satisfaction of the residents in the Rural Villages, it divided it into 'satisfaction with rural village life', 'satisfaction with housing' and 'satisfaction with village environment,' and compared and analyzed them with the physical environment of the Rural Village. Based on this, according to the type of local Rural Village, it analyzed with what part there were high relations with resident's satisfaction with the Rural Village. As a result, there was no significant difference between groups by the Rural villages, but residents were more satisfied with the natural environment of the village rather than individual housing. The analysis of the correlation between satisfaction with Rural villages and various factors, the more distance there is between the individual housing and the meeting facility, the lower their satisfaction with the Rural village became. In the future, when a community center or meeting facility is planned, it would heighten the resident's happiness when it is located at the physical center of the village rather than at the entrance of it.

Purpose: The small-scale environmental impact assessment conducted during the development project stage has focused on the preservation of the natural environment centered on non-urban areas, due to the nature of urbanization, health problems for citizens of high-density urban areas have a limitation in that they are relatively neglected. In the case of strategic environmental impact assessment and environmental impact assessment in urban areas, there is no basis for evaluation in urban areas because there are exceptions to be excluded from the target projects or there are no target project regulations for buildings. Therefore, in this research, we examined the problems with the target project such as the current environmental impact assessment, and tried to establish a system improvement plan that can solve them. Research design, data and methodology: After reviewing the current environmental impact assessment-related laws (including enforcement ordinances) and national land planning laws (including enforcement ordinances), exceptions such as environmental impact assessment in urban areas were identified and problems were identified. Based on this, an amendment to the Enforcement Decree was proposed to provide institutional support for the expansion of target projects such as environmental impact assessment in urban areas. Results and Conclusions: Through this research, it is expected that the projects subject to environmental impact assessment on development projects in urban areas directly related to the health of the people will be expanded, and the net function of the environmental impact assessment system will be maximized.

본 연구에서는 도시 지역 주민들과 농촌 지역 주민들을 대상으로 지리적 환경 차이에 따른 혈중 납 및 혈중 카드뮴 농도를 조사하여 노출 정도를 알아보고자 하였다. 연구 대상은 2007년 7월 1일에서 8월 30일 까지 경남의 전형적인 농촌마을(진주) 주민 84명과 부산 인근의 반농촌마을(기장) 주민 64명, 대도시 부산지역 주민 100명을 선정하여 연구를 수행하였으며, Graphite furnace를 갖춘 비불꽃 원자 흡광기를 이용하여 분석하였다. 평균 혈중 납 농도는 대도시 부산지역 주민이 $6.38{\pm}2.86{\mu}g/dl$이었으며, 진주 농촌지역 주민들은 $5.41{\pm}2.16{\mu}g/dl$, 부산 인근의 기장지역 주민들은 $4.50{\pm}2.87{\mu}g/dl$으로 부산지역 주민들의 평균 혈중 납 농도가 가장 높았으며 부산지역 주민의 혈중 납 농도와 부산 인근 기장지역 주민의 혈중 납 농도간 유의한 차이(p<0.01)를 보였다. 평균 혈중 카드뮴 농도는 대도시 부산지역 주민이 $0.85{\pm}0.44{\mu}g/l$이었고, 진주 농촌지역 주민이 $1.57{\pm}0.78{\mu}g/l$, 부산 인근의 기장지역 주민 $0.95{\pm}0.54{\mu}g/l$으로 진주 농촌지역 주민들의 평균 혈중 카드뮴 농도가 가장 높았으며 부산지역 주민과 진주 농촌지역 주민들 간에 통계적 유의한 차이(p<0.01)가 관찰되었다. 본 연구에서는 도시 지역과 농촌 지역 간에 따라 혈중 납 및 혈중 카드뮴의 농도에 차이가 있음을 알 수 있었으나, 일부 지역 주민들의 결과만으로 우리나라 전체 도시와 농촌지역 주민의 혈중 납 및 카드뮴 농도에 대한 차이를 단언하기는 어렵다고 생각된다. 하지만 작업장 내의 직업적 폭로가 아닌 도시와 농촌 간의 지역적 차이에 관한 연구로써 의미 있는 연구라 생각되며, 향후 혈중 납과 카드뮴의 체내 축척을 줄이기 위하여 보다 더 많은 대상자들의 정밀한 조사가 이루어져야 될 것으로 사료된다.

This study was carried out to investigate the levels of copper, zinc, manganese, nickel, cadmium and mercury content in breast milk among urban, rural and industrial lactating women in Korea. A total of 59 samples, which were collected from 17 in urban, 20 in rural and 22 in industrial area, and from 21-38 years-old healthy lactating women, were analyzed by Rigaku Mercury Analyzer for mercury, and by atomic absorption apectrophotometry for the other metals. The results are summarized as follows : The mean trace metal contents in breast milk were determined to be 0.34$\pm$0.14 ppm for copper, 2.01$\pm$1.43 ppm for zinc, 8.49$\pm$5.11 ppb for manganese, 7.75$\pm$5.73 ppb for nickel, 1.65$\pm$2.42 ppm for cadmium, 34.45$\pm$26.71 ppb for lead and 0.90$\pm$0.68 ppb for mercury. For the trace metal content in breast milk by area, the highest of copper, zinc, cadmium and mercury content were in urban, the highest of manganese content was in industrial, and the highest of nickel and lesd content were in rural. For copper, zinc, manganese and lead content in breast milk by lactation period, the highest levels were found in under 4 weeks after lactating, and subsequently the levels declined as lactation progressed, but the levels of zinc and manganese content increased from over 25 weeks after lactating. For cadmium and mercury content in breast milk by lactation period, the lowest levels were found in under 4 weeks after lactating, the highest levels were found in 5-12 weeks after lactating, and subsequently the levels declined as lactation progressed.For nickel content in breast milk by lactation period, the highest level was in 13-24 weeks after lactating, the lowest level was in 5-12 weeks after lactating.
