The sense of crisis regarding regional extinction due to low birth rates and an aging population is expanding. Generally, the local extinction index is used to analyze local extinction. However, it is challenging to diagnose the actual situation of village extinction risk in rural areas, even though the regional extinction index can be analyzed in units such as Si-Gun-Gu and Eup-Myeon-Dong. This difficulty arises because the regional extinction index solely relies on natural population growth indicators (elderly population and female population aged 20-39). Therefore, the purpose of this study is to develop a village extinction index that can identify the disappearance of rural villages. Additionally, the aim is to apply the developed indicators to the village (administrative ri) spatial unit. The existing regional extinction index used only mortality-related indicators as factors for natural population decline and fertility-related indicators as factors for natural population growth. However, the developed village extinction index included not only the factors of natural population change but also incorporated social population growth factors and factors related to the pace of village extinction. This is the key difference between the developed village extinction index and the existing regional extinction index. In this study, the indicators of "total population," "number of young women aged 20-44," "number of elderly population aged 70 or older," and "number of incoming population" were selected to develop a village extinction index. The village extinction index was developed by incorporating both natural population growth indicators and social population growth indicators. The developed village extinction index was applied to administrative villages. This research is expected to provide a more accurate understanding of the current state of rural villages facing extinction.

본 연구는 제주도에 이입된 황소개구리와 붉은귀거북의 분포현황과 서식실태를 파악하여 외래동물에 대한 데이터베이스 구축에 필요한 생물상 현황에 대한 기초자료를 확보하고 제주지 역에 적용 가능한 관리방안을 마련하고자 2005년 3월부터 2006년 5월까지 이루어졌다. 조사결과, 제주도내 황소개구리는 한경면, 대정읍, 안덕면 지역에 분포하는 것으로 나타났다. 제주도 서부지 역은 황소개구리의 서식 조건이 양호하여 쉽게 개체수가 감소하지 않을 것으로 생각되며, 다른 지역으로의 확산도 우려될 뿐만 아니라 토착 곤충류, 어류, 양서류, 파충류 등에 대한 피해가 예측되어 구제되어야 할 것이다. 그리고 붉은귀거북은 제주도내 15개소의 연못에서 92개체이상 서식하는 것으로 나타났다. 붉은귀거북은 최상위 포식자로서 연못의 생태계 파괴와 배설물에 의한 수질오염 문제를 야기할 수 있다. 붉은귀거북의 관리방안으로는 방생 자제 홍보, 생태적 습성을 이용한 퇴치방안, 인위적 확산을 막기 위해 다소 많은 개체가 서식하고 사람들의 왕래가 많은 서식지에는 위해성에 대한 홍보판 설치와 더불어 지속적인 관리가 따라야 할 것이다.

본격적인 인구감소 시대에 들어선 가운데 지방 도시들은 사회적 인구 유입도 어려운 상황을 고려하여 생활인구 유도를 통한 도시 활력 증진을 모색할 필요가 있다. 본 연구는 이동통신 빅데이터를 활용한 도시활력도 분석을 위해 인구감소 지역인 부산광역시 행정동을 대상으로 주민등록인구와 생활인구의 시공간 분포특성을 비교하였다. 다음으로 행정동을 인구증감의 변화 양상으로 유형화한 후, 도시쇠퇴 및 활력 관련 지표를 사용하여 유형별 지역 특성을 분석하였다. 시공간 분포특성 분석결과, 주민등록인구와 생활인구 밀도 분포패턴은 대체로 비슷한 패턴을 보였으나, 원도심 지역에서 주민등록인구 밀도가 낮으면서 생활인구 밀도가 높은 반대의 특성을 가지는 지역이 나타났다. 주민등록인구와 생활인구의 변화 양상은 상당한 차이를 보였으며, 주민등록인구는 밀도가 낮은 지역에서 인구가 감소하는 반면, 생활인구는 밀도가 높은 지역에서 감소하는 경향을 보였다. 생활인구 감소 군집에 인접해서 인구증감의 지역 간 격자가 큰 군집이 나타나, 인구 밀도가 높은 지역에서 주변 지역에 생활인구가 확산하는 전이효과가 나타날 가능성을 시사했다. 유형화 결과, 주민등록인구가 감소하는 지역에서도 통근·통학 또는 방문으로 인한 활발한 인구 유입이 있었으며, 이러한 지역은 사업체 수의 증가를 유지하고 있어, 산업·경제적 성장이 존재함을 확인하였다. 다만 부산의 약 47% 행정동은 주민등록인구와 생활인구가 모두 감소하고 지역 쇠퇴가 진행되고 있었으며, 이러한 지역에 대해 우선적인 도시 활력 증진을 위한 노력이 필요하다. 본 연구는 교통과 통신의 발달로 인한 도시활동의 한계거리 증가와 이동량의 증가로 지역간 교류가 날로 확대되는 점을 고려해 주민등록인구뿐만 아니라 도시계획지표로서의 생활인구 데이터의 활용 필요성을 제시하였다.

This research intends to discover the housing conditions of the elderly in rural area in South Korea, and identify measures to improve the conditions for an independent and safe life of seniors. This research conducted both survey research and experimental study. The survey interviewed 1,000 elderly people over 65 in farming areas across the country based on random selection from Census 2010 and sampling by regional size and administrative unit (Eup, Myeon, Li) to reflect the regional characteristics more accurately. The data was analyzed using SPSS 18.0 program. The experimental study identified the housing elements that may threaten the life of seniors based on a complete survey on households of elderly people over 65 in a selected typical rural village. As a result, the most inconvenient and threatening factor in the housing facilities appears to be the floor level difference. It was identified that most houses had the risk of falling due to the differences of the floor level between indoor and outdoor, and slippery floor materials. The squat toilets also bring inconvenience not only to the seniors with limited mobility but also to healthy elderly people. In particular, as most bathroom doors opened inward, it may be difficult to escape from or rescue someone in an emergency of falling, fainting or exhaustion.

The purpose of this study is to construct a quantitative evaluation method that can analyze the policy effectiveness with the construction of a implicit composite index incorporating spatial econometrics models. In order to propose a methodological framework for the program evaluation, this study conducts an empirical analysis with the application of the Comprehensive Rural Village Development Project (CRVDP) which explicitly claims to achieve comprehensive goal of community development. The present study pays particular attention to quantifying the composite evaluation index and drawing net effect through the application of a series of spatial econometrics models. The spatial unit of the analysis is drawn at Eup-Myeon level in rural areas in Korea, and the time horizon is in between 2005 and 2010. We utilize the Korean Agricultural Census data in 2005 and 2010. Three steps of methodological processes are needed to satisfy the objective of the present study. First, we apply factor analysis to construct the composite index that represents comprehensive settlement environment in rural area. The index should be matched with the main objective of the CRVDP. Second, we apply the derived index to a series of spatial econometrics model as dependent variable. Lastly, utilizing the estimated coefficients of the econometrics models, we apply decomposition technique to estimate CRVDP's net effect from both cross-sectional and longitudinal perspectives. We find that the results of the decomposition analysis by the execution of the CRVDP are positively associated with the explicit object of the project.

Background: The purpose of this study was to evaluate the association between metabolic syndrome and periodontal disease in Korean adults. Methods: This study analyzed the screening data of 12,686 adults aged ≥19 years, including demographic characteristics, lifestyle habits, and each component of metabolic syndrome, obtained from the sixth Korea National Health and Nutrition Examination Survey database. Periodontal health status was measured by the community periodontal index. Subjects with three or more risk factors were considered as having metabolic syndrome. The Rao-Scott chi-square test was performed to assess the relationships between demographic characteristics, lifestyle habits, components of metabolic syndrome, and periodontal disease. Logistic regression analysis was performed based on the complex sample to evaluate the relationship between metabolic syndrome and periodontal disease. Results: The prevalence of periodontal disease was higher among the subjects with advancing age, lower average household income and education level, those working in production, residents of eup-myeon areas, in past or current smoker, those with excessive alcohol consumption habit in a week, and reduced brushing frequency and the use of oral care products (p<0.001). Each component of metabolic syndrome was associated with higher prevalence of periodontitis in the subjects with abnormal than in those with normal levels (p<0.001). The prevalence of periodontal disease in subjects with metabolic syndrome was approximately 1.443 times higher than that in normal subjects (odds ratio,1.443; p<0.001). Conclusion: This study confirmed the association between metabolic syndrome and periodontitis in Korean adults, and further studies will be needed to determine the causal relationship between the two conditions.

All of the animals and the plants in ecosystem are intimately connected to one another and the changes of forests and surroundings affect directly wild animals. This study was conducted at Hangyeong-myeon Cheongsu-ri located in the western part of Jeju Island belonging to Hangyeong Andeok Gotjawal Zone and Jocheon-eup Seonheul-ri located in the eastern part of Jeju Island belonging to Jocheon Hamdeok Gotjawal Zone. The survey on advent of birds was carried out twice a month from January 2014 to December 2015. We divided habitat environments into three survey sites such as a forest, a shrub forest and a farmland. A total of 65 species and 4,802 individuals were observed during the survey period. In a forest, 36 species and 1,287 individuals were observed while A shrub forest had 40 species and 1,554 individuals. And in a farmland, 41 species and 1,961 individuals were observed. The only 10 species were observed in forest and the only 7 species in shrub forest and the only 10 species in farmland. The species diversity and the evenness of a farmland were the highest, and the species richness was the highest in a shrub forest, and the dominance of a forest was the highest among the three areas. The similarity index between a shurb forest and a farmland was high while that between a forest and a farmland was low. The similarity index related with breeding appeared that a forest and a farmland was different from each other.

This study analyzes the material characteristics of stone tools of the Paleolithic period excavated from the Osong site, located at the project site for the creation of the Osong 2nd Life Science Complex, and estimates the provenance of the stone materials. Because the stones had been buried for a long time, their surfaces had become heavily weathered yellow or yellowish-brown, and the magnetic susceptibility values varied from 0 to 15(${\times}10^{-3}SI$). The excavated stone tools were rocks with various magnetic susceptibility values that could not be specified. Five stone tools subjected to destructive analysis were divided into two groups, one with a value of 1-3(${\times}10^{-3}SI$) and the other with a value of 5-9(${\times}10^{-3}SI$), both based on visible characteristics. The results of the thin-section analysis showed that most of the stone tools were basaltic rocks comprising plagioclase, quartz, and pyroxene, and some had iron content as high as 20 wt.%. These findings and the present geological map suggest that the stone tools were not made from the surrounding rocks because there are no areas containing basaltic rocks surrounding Bongsan-ri in Osong-eup. Andesite and tuff are distributed along with basaltic rocks in the Doan-myeon area in Jeongpyeong-gun, Chungcheongbuk-do Province, but the distance from the excavation site is too far. To determine whether this region is actually related to the provenance of the raw rock, it is necessary to conduct additional field surveys and comprehensive and precise analyses.
