The purpose of this study was to classify parks by type and to propose management plans for each park type. Environmental characteristics of urban parks in Daegu Metropolitan City were used to classify them into five categories. A total of 68 neighborhood parks were classified using their internal/external environmental factors, with a resulting distribution of 41 parks classified as 'FFR-type parks,' 12 as 'HNR-type parks,' 6 as FFCI-type parks,' 3 as FFA-type parks,' and 6 as 'HNA-type parks.' In the analysis of ecological and usage characteristics for the neighborhood park types, FFR-type parks had excellent park accessibility and the highest population density within the park service area. HNR-type parks had high NDVI from their natural green spaces, but their accessibility was low. FFCI-type parks had very low NDVI and green space connectivity, and also had low park accessibility and population density. FFA-type parks had low NDVI and green space connectivity, and very poor accessibility. HNA-type parks had high NDVI and green space connectivity. These findings provide an effective base dataset for use in preparing long-term plans for remodeling and managing urban neighborhood parks.

Most extended care facilities have admitted both the healthy and unhealthy elderly, among which members' average caring demand vary. The Aged Welfare Law, however, currently provides no reasonable basis on the staffing policy for extended care facilities. It just reflects the admitted number of the elderly rather than differences in members' average caring demand among facilities. This study is designed to estimate the need for caring staff on the basis of the correlation between the individual health status measured by various tools including Activities of Daily Living and caring demand by actual service time for each one. The sample included all of the admitted elderly(187 persons) in 4 extended care facilities, two in Seoul and the other two in Kangwon-Do over the survey period October 5 through October 20, 1996. The survey process consisted of 3 stages. (1) The current staffing information was collected through self-completed written questionnaires left for head of official in each facility. (2) Six graduate students at School of Public Health interviewed all residents to collect information on their health status and sociodemographics. The response rate for the interview was relatively high(85%). (3) Information on direct and indirect caring time consumed for each residents came from self-completed written questionnaires given to nurses and helpers in each target facilities. Analysis of the data was made using Pearson's correlation and multiple regression technique through SAS program. Based on this procedure, the following was found. 1. No facility meet the staffing standard in the Aged Welfare Law completely. 2. It is actual service time that is most correlated with ADL(Activities of daily living). 3. When all of the elderly are divided by four groups based on the level of ADL, the mean values of needed caring time in each group are 15, 21, 36 and 88 minutes respectively. 4. There is no significant difference among facilities in distribution of elderly person by group. 5. No facility meets the estimated number of nurses and helpers which reflects health status of the admitted elderly. Therefore, it is required that severity of the admitted elderly be considered in establishing staffing standard for extended care facility.

최근 기후변화로 인해 설계 빈도 이상의 강우가 빈번하게 발생하고 있으며 이러한 집중호우에 의한 피해는 지역별로 토지이용, 사회 환경적인 조건에 따라 차이가 있다. 특히 인구와 경제 제반 시설이 밀집되어 있는 도시지역의 경우 홍수가 발생하게 되면 피해가 과거에 비해 큰 규모로 나타나고 있다. 현재 각 지자체는 홍수 대응을 위해 기상청에서 제공하고 있는 6시간, 12시간 강우량을 기준으로한 호우주의보 및 경보를 사용하고 있다. 하지만 도시지역의 경우 지속시간이 1~2시간인 짧은 호우에서 피해가 발생하여 기상청에서 제공하고 있는 홍수특보를 활용하는데 있어 한계가 있다. 또한 이러한 기준은 각 지역별 사회 경제적 특성을 반영하지 않아 지역별 실질적인 홍수 대응에 효과적이지 않다. 따라서 각 지역별로 특성을 파악하여 홍수에 대한 피해를 저감하기 위한 대책 수립이 필요한 실정이다. 본 연구의 공간적 범위로 한강권역에서 서울시와 인천시의 경우 '구 단위', 경기도와 강원도, 충청북도는 '시 군 단위'로 총 88개 행정구역으로 하고 도시별 특성에 따라 군집화를 위해 환경적, 사회적 및 경제적 특성 중 홍수에 대한 취약성을 반영할 수 있는 인자를 선정하였다. 선정된 인자들을 주성분분석을 통해 공통된 특성이나 유사한 성질에 따라 공통인자를 추출하고 이를 이용하여 각 도시별 군집분석을 시행하였다. 그 후 각 도시 군집별 특성에 따라 홍수에 의한 피해를 가장 잘 나타낼 수 있는 인자를 위험영향(Risk Impact)으로 산정하였다. 이때 위험영향은 강우규모에 따른 잠재 피해 정도를 나타내며 홍수위험도표를 작성하기 위해서는 이러한 위험영향을 정량적으로 설명할 수 있어야 한다. 본 연구에서는 각 도시 군집별 특성에 따른 위험영향의 임계값을 추정하고 그에 따른 홍수위험도표를 작성하였다.

Urban parks play the role of providing leisure spaces for people in their everyday life along with serving ecological functions in the city. Although urban parks aim to satisfy the needs of users visiting the park, most urban parks are currently uniformly created and maintained without considering the environmental characteristics based on the needs of users. This study thus analyzed parks that underwent modifications in line with the revised Park Act in 2005. There were 45 parks whose types were legally changed, of which 21 were changed from children's parks to small parks, and 19 were changed to utilize and highlight the themes such as cultural parks and historical parks. Among the parks whose types have changed, the ratio of amenities in cultural and historic parks has increased, while the facility area in small parks has decreased and the green area has increased in its place. As a result of analyzing the changes to the park facility area, it was confirmed that increasing park amenities has a positive effect in pursuing revitalization of use through park maintenance, but has a negative consequence of significantly decreasing green area. It is necessary to reorganize the park type classification system to reflect the park environment and prepare guidelines for a new installation standard by park type to expand the net function of parks in cities and maintain the sustainable ecological environment. Through in-depth discussions on the facilities of park types, it is anticipated that innovative and multilateral research could be conducted to prepare improvement measures tailored to the guidelines of urban park types in years to come.

The objective of this study is to identify the causes of pedestrian volume path to the destination by investigating the influential levels of regional and planning features in the central area of Seoul. Regional characteristics can be classified from the result of the analysis and through the spatial characteristics of pedestrian volume. For global scale analysis, Ordinary Least Squares (OLS) regression is used for the degree of influence of each characteristics to pedestrian volume. For the local scale, Geographically Weighted Regression (GWR) is used to identify regional influential factors with consideration for spatial differences. The results of OLS indicate that boroughs with transportation facilities, commercial business districts, universities, and planning features with education research facilities and planning facilities have a positive effect on pedestrian volume path to the destination. Correspondingly, transportation hubs and congested areas, commercial and business centers, and university towns and research facilities in the Seoul central area can be identified through the results of GWR. The results of this study can provide information with relevance to existing plans and policies about the importance of regional characteristics and spatial heterogeneity effects on pedestrian volume, as well as significance in the establishment of regional development plans.
