  • In this study, we analyzed the characteristics of 511 agricultural districts through statistical data, and classify these districts as the vulnerable area to drought through correlation and cluster analysis. The criteria for classification was related to ground-water recharge, irrigation water demand, and water supply. As a result, 8 types of agricultural districts were extracted. For example, the type 1 indicated the high priority area for ground-water development, thus the districts which were classified as type 1 showed ground-water use was less than 80 % of maximum capacity, and irrigation water supply was only 37.5 % and 76.5 % of irrigation water demand in upland and paddy field, respectively. As a result, 44 of 511 districts were classified as type 1.36 districts (types 5-8) were areas where groundwater development is limited. The results of this study are expected to provide useful information for establishing the direction of the rural area development project in connection with the revitalization of policy of people return to rural area.

  • 소방서는 지역주민의 생명과 재산을 지키는 중요한 공공기반시설로 화재발생시 신속하게 대응하여 피해를 최소화할 수 있도록 최적의 입지에 위치해 있어야 한다. 하지만 접근성과 재난발생요소들을 고려하지 않는 소방서 입지는 편중된 소방서비스를 야기할 수 있다. 따라서 재난안전 사각지대 해소 및 소방서비스의 균등한 제공을 위해 효율적인 소방서 입지를 위한 서비스 분석이 필요하다. 특히 재난의 발생 기능성이 높은 취약지역을 최소화함으로서 효율적인 소방서비스를 제공하여야 한다. 본 연구에서는 효율적인 소방 서비스 제공을 위한 기초연구로서, 화재 등 재난발생의 취약성을 나타내는 값을 색인화한 지도와 소방서의 서비스지역을 나타내는 지도를 도출하는 방법을 제시한다. 중첩분석을 통해 서비스 지역을 나타내는 지도와 취약성을 나타내는 지도 사이의 공간적 분포의 불일치를 파악하고, 소방서비스의 취약지역을 도출한다.

  • Background: The purpose of this study is to identify the factors infecting the medical care utilization from a new perspective by newly classifying the categories of administrative districts using the urban decline index and medical vulnerability index as indicators. Methods: This study targeted 150,940 people who used medical services using the 2015 cohort database (DB), 2010-2015 urban regeneration analysis index DB, and 2014-2015 public health and medical statistics DB. The decline of the region was classified using the urban decline index typed using k-means clustering and the medical vulnerability index typed using the quantile score calculation. Regression analysis was performed 3 times with medical expenditure, length of stay, and the number of outpatient visits as dependent variables. Results: There were 37 stable region (47.4%), 29 health vulnerable region (37.2%), and 12 decline region (15.4%). The health vulnerable region had lower medical expenditure, fewer outpatient visits, and a higher length of stay than the stable region. The decline region was all higher than the stable region but had no significant effect. Conclusion: The factors that cause the health disparity between regions are not only factors related to individual health behavior but also environmental factors of the local community. Therefore, there is a need for a systematic alternative that properly considers the resources within the community and reflects the characteristics of the population.

  • 본 연구는 한국인의 정신건강이해력(MHL)을 평가하고 취약집단을 분석하기 위한 목적을 가지고 있다. 이를 위해 전국의 연령별, 지역별 인구비례에 따라 표집 된 성인 1,197명을 대상으로 정신분열병, 우울증, 알코올중독 사례를 무작위로 배정하여 각 사례의 정신질환 인식률, 원인에 대한 이해, 치료법과 치료자원에 대한 이해, 정신과치료에 대한 낙인을 조사하였다. 그 결과 우리나라의 MHL은 매우 낮음을 알 수 있다. 전반적인 인식률도 낮지만 특히 정신분열병에 대한 인식률이 매우 낮았다. 원인 또한 사회적, 생물학적 원인보다 개인적 원인을 선호하였고, 심리상담을 제외한 전문적 치료의 유용성을 자가 치료보다 낮게 인식하였다. 전문가 중에서는 정신과전문의의 유용성을 가장 높게 인식하였지만 이것 역시 가족보다 낮은 수준이다. MHL 취약집단을 분석하기 위해 군집분석을 실시한 결과 MHL이 높은 집단과 낮은 집단의 차이는 원인에 대한 이해와 치료방법과 자원에 대한 이해에서 나타났다. 낮은 집단의 특성은 남성이 많고, 60대 이상이며, 군 이하 지역에 거주하는 사람으로 분석되었다. 이러한 결과를 바탕으로 연구자들은 정부 주도하의 대중매체를 활용한 MHL 향상 프로그램을 제안하고 취약집단에 대한 우선적 개입의 필요성을 주장하였다.

  • This research challenges the general notion of one-person households of the elderly during widowhood as impoverished, isolated, and vulnerable. Recognizing a high potential vulnerability, however, this research attempts to describe the diverse composition of one-person households of the elderly. For this purpose, relying on 2% sample data from the 2000 census, it examines regional distribution, socio-economic characteristics, and determinants of one-person households of the elderly during widowhood. Socio-economic characteristics of one-person households of the elderly differ by region. Jeju island is distinct in terms of sex and age distribution, and residence area of children. In general, rates of economic activity and self-subsistence are higher in provinces than in cities. Compared to the elderly living with family, the elderly living alone show high rates of economic activity, self-subsistence, and capability of physical activity. Results of logistic regression analysis of determinants of living arrangement are consistent with those of descriptive statistics. Those who are economically active and able to move around without assistance tend to live alone after the death of a spouse. Number of sons and living in an urban area are negatively associated with living alone, whereas females are more likely than males to live alone. According to the separate analysis by age, the positive effect of economic activity is greater in the oldest of the old than in other age groups. Those who possess high educational attainment tend to live alone when they are 80 and older, unlike other age groups. Based on these findings, this paper finds that one-person households of the elderly nay not always be the most vulnerable group, and are diverse in terms of socioeconomic characteristics.

  • Recently the life damage is increasing due to the house disruption and burying accident by the landslide, and most of the damages are concentrating on the agricultural area. This study is a basic study for developing the personal disaster evacuation apparatus that can be installed in the house for the people in agricultural area vulnerable to the disaster in case of the landslide. This study carried out the numerical analysis and the object load test on the personal disaster evacuation apparatus. As a result of this study, it was judged the life damage could be minimized if the personal disaster evacuation apparatus using the glass fiber reinforced plastic (GFRP) materials was installed in the steep slope-land with a high possibility of the disruption.

  • Objectives Children are one of the most vulnerable populations to the impact of disasters. We aimed to examine children's mental health in the area affected by the Hebei Spirit oil spill accident on December 7, 2007. Methods A cross-sectional questionnaire survey was conducted using the Korean versions of the Children's Depression Inventory and State Anxiety Inventory for Children on 1,362 children attending elementary schools in the affected area. The information on distances between the nearest contaminated coastline to the child's residential house or attending school were obtained using a web-based map by inputting two address points. The symptom risks of depression and state anxiety were estimated by multiple logistic regression analyses adjusted for age, gender, and other covariates. Results Children with the closest distance (in the fourth quartile) to the school from the contaminated coastline showed a significantly higher symptom risk of depression compared to those with the farthest distance (first quartile)(odds ratio, 2.73; 95% confidence interval, 1.40-5.33), while there was no significant association between anxiety symptoms and distance. Conclusions Children, a vulnerable population for mental health impact by the oil spill accident, should be included in mental health programs in the community along with their family as victims of the disaster.
