This study aims to analyze the accidents of green mode bicycle. In pursuing the above, this study gave special emphasis on modeling the bicycle accidents reflecting the regional characteristics. The main results are as follows. First, the null hypotheses that the number of accident and ratio of serious injury and fatality (FSI) were the same over regions were rejected. Second, as the common variables, the number of bicycle was judged to have positive (+) impact to the accidents and the bicycle using ratio was inferred to increase the ratio of FSI. Third, the elderly population ratio among 3 factors which gave impact to the accidents of Si_A (city-county consolidation) was concluded to have the greatest elasticity. The developed area ratio between 2 factors in Si_B (city which is not consolidated) was, however, estimated to have the higher elasticity. Fourth, the number of car registration among 5 accident factors of Gun (county) was analyzed to have the greatest elasticity. Finally, the commuting trip ratio among 7 accident factors of Gu (district) was judged to have the greatest elasticity. This study can be expected to give some implications to regional policy-making related to bicycle.

The purpose of this study is to analyze the determinants of start-ups by industry based on the theoretical background of entrepreneurship. For this purpose, regional industrial structure and local labor market structure are considered in order to focus on regional factors in addition to economic factors, income factors, and technological innovation factors. As an analyzed result, three theories of entrepreneurship generally agree with the determinants of industry - specific entrepreneurship. During the economic recession, the number of start-ups has increased. The intra-regional consumption and the local government expenditure per capita have also positive effects on the start-up. The incubation center has a positive effect on the start - up in the manufacturing sector. Therefore, the academic-industrial leading various incubation facilities should be activated in addition to the central or local government leading incubation centers, which is a part of the policy to support start-ups of central and local governments. In addition, population growth is a very important factor in terms of potential demand creation, and the characteristics of regional industrial structure and the effect of human capital within the region differ by industry. In the case of the manufacturing industry, the accumulation effect positively influences the start-up of the industry. In other service industries, the human capital variable had the greatest effect on the start-up when all other conditions are constant.

Geochemical characteristics, water quality, $NO_3{^-}$ contamination and the origin of $NO_3{^-}$ were analyzed for the groundwater located at Ogcheon, Korea. The water qualities were weakly acidic to weakly alkalic and redox potentials indicated reduction condition. Compared to granitic rocks, metamorphic sedimentary rocks with intercalations of limestones and dolomites tended to be more effectively dissolved, resulting in higher pH and higher concentrations of dissolved ingredients. Contamination of heavy metals was not revealed. Geochemical reactions of carbonate rocks and influxes of artificial contamination ingredients seemed to simultaneously determine the geochemical characteristics and water qualities in the study area. From the results of ${\delta}^{15}N$ isotope analysis, the origin of $NO_3{^-}$ was estimated to be influenced dominantly by agricultural activities and human feces and urine.

최근 기상이변의 가속화로 인해 홍수피해는 더욱 증가되고 있으며, 도시화로 인해 불투수면적이 급격히 늘어남에 따라 기존 관개수로의 통수능력 부족으로 도시침수피해가 증가되고 있다. 재난 연감과 재해연보를 바탕으로 비교한 결과, 홍수를 비롯한 각종 재난 발생 시 일반적으로 남성들에 비해 여성들의 피해자 수가 많으며 피해의 정도는 상대적으로 심각하였다. 그러나 국내외적으로 홍수에 대한 피해를 줄이고자 홍수 취약성에 대한 많은 연구들이 수행되었지만 아직 젠더를 고려한 취약성 분석은 부족한 실정이다. 본 연구에서는 대상지역을 우리나라의 인구밀집도가 가장 높은 서울시 25개구로 선정하였고, 엔트로피 이론을 활용해 25개 구의 홍수 취약성 지수를 계산하였다. 홍수 취약성 지수 계산 시 고려요인으로는 여성인구비율, 고령화비율 및 인구밀도 등과 같은 사회적 요인과 연 홍수 피해액, 복구금액 등 경제적 요인 그리고 일일 최대 강수량 및 80mm 이상의 강수량, 홍수 피해 횟수 등과 같은 환경적 요인을 고려하였다. 그 결과 각각의 요인에 따라서 서울시 25개구의 홍수취약성 지수가 상이하게 나타나는 것을 확인할 수 있었다. 이를 통해 취약성지수가 높은 자치구들의 경우 지역특성을 고려한 별도의 홍수대책 가이드라인이 필요 할 것으로 판단된다. 본 연구의 결과물을 바탕으로 향후 홍수 대책이나, 홍수대비 관련 정책을 수립할 정부 및 지자체에서 사회, 경제, 환경적 요인을 고려한 합리적인 정책 수립 결정에 도움이 될 것으로 판단된다.

The young generation in life cycle that social position is rapidly changing is play an important role in a regional development because they can increase social and natural population in the region. This study analyzed the relationship between the movement of young generation and the regional characteristics including housing market characteristics in Seoul. As the results, the movement of young generation was influenced by commuting distance and location of jobs as the gravity model has suggested. In addition, housing supply and housing price (or Jeonse price) is an important factor for the movement of young generation. It can be inferred that the more price gap such as Jeonse price and housing supply gap are increased, the more out-migration of young generation in Seoul is increased. However, the housing demand of young generation in employment centers will be increased because jobs contribute to increasing the inflow of young people. Therefore, the policies of central and Seoul government that supply housing in job rich and high accessibility areas are needed for young generation. In addition, if public housing and affordable housing are supplied in the other areas, it can contribute to reduce the out-migration of young people in Seoul.

This study utilized CART algorithm, a decision tree analysis method, to comparatively analyze factors affecting housing and residential environment satisfaction by region using data from Ministry of Land, Infrastructure and Transport's housing survey in 2020. First, in terms of residential environment satisfaction, accessibility to medical facilities and school district showed higher importance in metropolitan cities and areas compared to other regions, whereas safety from accident showed the opposite trait, showing difference between region. Second, housing characteristics were important in housing satisfaction, indoor environment level satisfaction and indoor safety and hygiene being important in almost all regions, while residential environment characteristics were more important in residential environment satisfaction and influencing factors were relatively evenly distributed. In order to generalize these regional characteristics, research using time series data needs to be conducted later.

The purpose of this study is to analyze the difference in suicide rates between regions and to determine the effect of social workers on the regional suicide rate. The main analysis results are as follows. First, the suicide rates in metropolitan cities were lower than was lower than in other regions, and cities and districts were lower than those in the county area. Second, suicide rates were high in areas with many cultural and social welfare facilities per population. Suicide rates were high in low mental health facilities and low social welfare budgets. The suicide rate in rural areas was high. Third, suicide rates were high in areas with low economic requirements, areas with a high proportion of the elderly, divorce rates, and areas with a small number of social security recipients and living alone. In other words, the suicide rate in rural areas was high. Finally, social workers did not affect the difference in local suicide rates. Local social services and budgets have no real impact on suicide rates. In the future, it is necessary to improve the quality and quantity of community welfare practices that can lower community suicide rates.

This study was carried out to analysis factors related to in-hospital mortality of community-acquired peumonia using administrative database. The subjects were 5,353 community-acquired pneumonia inpatients of the Korean National Hospital Discharge Injury Survey 2004-2006 data. The data were analyzed using chi-squared test and decision tree model in the data mining technique. Among the decision tree model, C4.5 had the best performance. The critical factors on in-hospital mortality of communityacquired pneumonia are admission route, respiratory failure, congenital heart failure including age, comorbidity, and bed size. This study was carried out using the administrative database including patients' characteristics and comorbidity. However further study should be extensively including hospital characteristics, regional medical resources, and patient management practice behavior.
