  • In this study, we have simulated regional climate over East Asia using dynamical downscaling For dynamic downscaling experiments for regional climate simulation, MM5method. with 27 km horizontal resolution and 18 layers of sigma-coordinate in vertical is nested within global-scale NCEP reanalysis data with 2.5。${\times}$2.5。 resolution in longitude and latitude. In regional simulation, January and July, 1979 monthly mean features have been obtained by both continuous integration and daily restart integration driven by updating the lateral boundary forcing at 6-hr intervals from the NCEP reanalysis data using a nudging scheme with the updating design of initial and boundary conditions in both continuous and restart integrations. In result, we may successfully generated regional detail features which might be forced by topography, lake, coastlines and land use distribution from a regional climate. There is no significant difference in monthly mean features either integrate continuously or integrate with daily restart. For climatologically long integration, the initial condition may not be significantly important. Accordingly, MM5 can be integrated for a long period without restart frequently, if a proper lateral boundary forcing is given.

  • 이 연구의 목적은 질병관리본부의 퇴원손상환자조사 자료를 이용하여 경제적 수준이 낮은 지역이 그렇지 않은 지역에 비해 다른 운수사고 양상을 보이는지를 규명하는 것이었다. 지역의 경제적 수준은 재정자립도를 지표로 삼아 5개로 구분하였다. 이 연구의 주요 결과는 다음과 같다. 첫째, 운수사고는 25-44세 그룹까지 증가하다가 그 이후에는 감소하는 양상을 보였다. 둘째, 운수사고의 유형은 승용차의 빈도가 가장 높았고 길 또는 간선도로에서 가장 많은 사고가 발생하였다. 셋째, 지역에 따라 운수사고 유형에 차이가 있었다. 넷째, 응급 입원율은 지역에 따라 차이를 보였으나, 소득수준에 따른 차이는 없었다. 마지막으로 소득수준이 낮은 지역은 골절, 자상, 개방성 상처와 같이 심각한 손상이 주로 발생하고 소득수준이 높은 지역은 염좌, 긴장, 탈구와 같이 상대적으로 덜 심각한 손상이 주로 발생하는 등 손상 양상의 지역간 차이가 발생하고 있었으며 이러한 지역간 차이는 통계적으로 유의하였다(p<0.05). 따라서, 지역간 소득 수준에 따라 운수사고 양상이 차이가 발생하고 있으므로 정부 및 지방자치단체는 이를 고려한 차별화된 운수사고 예방전략을 수립해야 할 것이다.

  • 본 논문은 정부가 시행한 1차 계절관리제의 초미세먼지 농도 감소 효과를 통계적 기법을 통해 확인하는 것이다. 특히 본 논문은 이러한 정책효과가 지역별(서해안, 남해안, 동해안)로 차이가 발생할 수 있다는 가설을 검정하는 것이다. 이를 위해 본 논문은 이중차분법(DID, difference-in-difference)을 활용하여 정책 시행 기간(2019년 12월~2020년 3월) 지역과 무관하게 발생한 코로나19, 따듯한 겨울 등 시간적 특이성을 제거하여 순수한 정책효과만 분석하였다. 분석 결과 석탄화력발전소에 대한 정부의 1차 계절관리제는 초미세먼지 감소 효과가 있었으나, 지역별로 그 효과에 차이가 존재하였다. 특히 서해안 지역의 감소 효과가 가장 크고, 남해안 지역이 그다음으로 효과가 있었으나 동해안 지역의 경우 감소 효과가 통계적으로 확인되지 못했다. 결과적으로 본 논문은 현재와 같이 지역과 무관하게 계절관리제를 운영하는 방식은 개선될 필요가 있다는 시사점을 도출하였다.

  • Regional variation in the fatty acid content of shellfish was investigated on 5 species of Korean shellfish including murex shell, ark shell, jack-knife clam, orient hard clam, and little neck clam that were originated from 2 geographically different regions in Korea (Region 1: South coast, $34-35^{\circ}N$, $127-129^{\circ}E$; Region 2: West coast, $36-38^{\circ}N$, $126-127^{\circ}E$). Significant regional difference in total fatty acids content was observed in murex shell and little neck clam (p<0.01), but not in the other species of shellfish. The contents of saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids including n-3 and n-6 fatty acids were appreciably higher in murex shell from Region 2 and in little neck clam from Region 1 than the shellfish originated from their counterpart areas (p<0.05). Nevertheless, relative percentages of the fatty acids remained constant within same species regardless of geographic regions or species. Considering the facts of that the fish/shellfish are unique sources of n-3 fatty acids and a little neck clam is the most-consumed shellfish in Korea, n-3 fatty acids intake might vary with the habitat of the shellfish that Koreans consume.

  • Recent expansion of urban parks has been partly successful in terms of providing urban outdoor recreation space. Unfortunately we paid very little attention to the importance of providing regional identity to urban parks until recently. Thus one of the most important tasks of the contemporary landscape architects of Korea is to investigate ways to improve regional identity of urban parks. This study is aimed at evaluating how well the current urban parks have realized their own regional identity. To test the effectiveness of the concept of 'identity', the identity items were created, while a research model was developed by using such variables as in urban park identity, park satisfaction, belongingness to the region, and residential satisfaction. In order to test the model, the causations were analyzed. Meanwhile, the scales to evaluating identity were reviewed by means of the unstructures group interview, and were finally determined as 10 items; culture, uniqueness, symbolic, historic nature, homogeneity, harmony, difference, public benefit, nativeness and traditionality. Data from three new towns in the capital region-Bundang, Ilsan and Sanbon-were collected, and their central parks were referred to a questionnaire survey. The data were processed using descriptive statistics, correlation analysis, multiple regression analysis and path analysis. It was found through this survey that subjects 'sentiments regarding the sample towns' regional identity differed slightly. Residents of Bundang felt the strongest amount of regional identity, followed by those of Ilsan and Sanbon. In addition, the most important scale on regional identity is 'park satisfaction', followed by 'belongingness to the region' and 'residental satisfaction'. The path analysis was conducted to interpret the causations in a more detailed and comprehensive way than correlation analysis. As a result, it was proven that the regional identity affects 'belingingness to region' through the intermediated variable 'park satisfaction', while affecting ' residential satisfaction' through the intermediate variables 'park satisfaction' and 'beligningness to region'. In other words, although the regional identity of a park does not directly affect 'belongingness to region' or 'residental satisfaction', it has indirect effects on them through intermediate variables.

  • Background: Unmet healthcare needs have many advantages for measuring inequalities in healthcare use. However, the existing indicator is difficult to capture the reality of unmet healthcare needs sufficiently and is not quite appropriate in comparing regional inequality. The purpose of this study is to critically analyze the utilization of the unmet healthcare need indicator for regional healthcare inequalities research. Methods: We used the level of healthcare accessibility and healthcare need to categorize the regions that are known to cause differences in healthcare utilization between regions and verified how existing unmet healthcare need indicator is distributed at the regional level. Results: Four types of regions were classified according to the high and low levels of healthcare needs and accessibility. The hypothesis about the regional type expected to have the highest unmet healthcare need was not proved. The hypothesis about the lowest expected regional type was proved, but the difference in the average rate of unmet healthcare needs among regional types was not significant. The standard deviation of the rate of unmet healthcare needs among regions within the same type was also higher than the overall regional variation, which also disproved the whole frame of hypothesis. Conclusion: Failure to prove the hypothesis means the gap between the supposed meaning of the indicator and the reality. In order to understand the current state of healthcare utilization of people in various regions of Korea and to resolve inequality, fundamental research on the in-depth structure and mechanisms of healthcare utilization is needed.

  • Purpose: The coronavirus disease 2019 (COVID-19) pandemic has necessitated a redistribution of resources to meet hospitals' service needs. This study investigated the impact of COVID-19 on a regional trauma center in South Korea. Methods: We retrospectively reviewed cases of polytrauma at a single regional trauma center in South Korea between January 20 and September 30, 2020 (the COVID-19 period) and compared them to cases reported during the same time frame (January 20 to September 30) between 2016 and 2019 (the pre-COVID-19 period). The primary outcome was in-hospital mortality, and secondary outcomes included the number of daily admissions, hospital length of stay (LOS), and intensive care unit (ICU) LOS. Results: The mean number of daily admissions decreased by 15% during the COVID-19 period (4.0±2.0 vs. 4.7±2.2, p=0.010). There was no difference in mechanisms of injury between the two periods. For patients admitted during the COVID-19 period, the hospital LOS was significantly shorter (10 days [interquartile range (IQR) 4-19 days] vs. 16 days [IQR 8-28 days], p<0.001); however, no significant differences in ICU LOS and mortality were found. Conclusions: The observations at Regional Trauma Center, Pusan National University Hospital corroborate anecdotal reports that there has been a decline in the number of patients admitted to hospitals during the COVID-19 period. In addition, patients admitted during the COVID-19 pandemic had a significantly shorter hospital LOS than those admitted before the COVID-19 pandemic. These preliminary data warrant validation in larger, multi-center studies.

  • The purpose of this research is to apply the regional development attractiveness of the national level determined in the previous study to the city and county level of Chungcheongnam-do. We verified results with the population change of the floating population data. In order to measure regional development attractiveness in 2020, Chungcheongnam-do's integrated air environment index and per capita gross regional product were gathered. Population movement data over the past five years have been used to analyze population changes in the floating population data. Regional development attractiveness depended on the data of GDP per capita, which had a large difference between the maximum and minimum values. The rate of increase or decrease in population change by city and county in Chungcheongnam-do over the past five years has changed significantly since 2021 and characteristics of each group were grouped into four groups. Based on the environment and economic feasibility of the region, it can be the starting point for a new analysis of Korea's regional development projects and the selection of target sites. Policy suggestions can also be made in spatial plans such as short-term comprehensive plans, long-term comprehensive plans, and development plans. It can be a limit of this research that regional development attractiveness was determined by the relatively large per capita gross domestic product. It is necessary to further develop regional development attractiveness by closely investigating the characteristics of the region, social problems, and emissions of environmentally harmful substances.

  • There are recently many studies on evaluating the economic value of multi-functionality of rural areas. However, the regional difference of economic value leads a problem of different evaluation on its economic value for each region in its application to government policy. This problem causes an increase in cost because it creates restriction in policy decisions which put their importance on the time of their execution. This study investigates the propriety of value transfer using Meta Analysis after evaluating the social and cultural value of rural areas among their functions based on CVM model. It finds that the regional difference in the willingness to pay is 0.13% to 31.42%.
