The purpose of this study was to provide basic information about hierarchical spatial compositions of lounges and corridors in elderly skilled nursing facilities through the analysis of elderly residents' behaviors. For the study, five researchers observed the behavior of the elderly in the lounges and corridors of five facilities from 10 AM. to 4 PM. at 30-minute intervals for the investigation of hierarchical spatial compositions. And then, the design characteristics of public and semi-public area were analyzed by evaluating their openness, centrality, accessibility, and stimulations. The results of this study were as follows. First, the public area was focused on the lounge, and the semi-public area was formed on the comers of corridors and the parts of lounge walls. The private and semi-private area were distributed to the whole lounges and corridors. Second, in morning time, the semi-public area was concentrated on the wall of lounge instead of on the comers of corridors, and in afternoon, the residents' behaviors relevant to the private and semi-public areas were increased. Especially, the comers of corridors were utilized as the main semi-public areas. Third, the public area could encourage the participation of the elderly residents when it was opened to other areas more than 40% and close to the nursing station. But, the central garden made the accessibility from the elderly private room to the public area not good. The ideal openness of semi-public area was indicated as 25-30%, and its centrality was $10{\sim}15m$ which was a little far from the nursing station. Forth, furniture arrangements gave large influence to the behavior characteristics in the semi-public areas. Especially, sofa arrangements in the comers of corridors increased informal interactions among the elderly. In conclusion, the public area needs high rate of openness and should satisfy both of the centrality and accessibility so that it lead the elderly participations from the private and semi-private areas. The semi-public area should be in a little distance from nursing station and provide with furniture sets for the elderly informal interactions.

최근 대중교통지향형개발(TOD)이 활발해지며, 역세권의 환경 변화를 통하여 국내의 대중교통 이용 증진을 시키기 위해서는 TOD 통합계획요소를 종합적으로 고려한 역세권 유형과 이용수요에 관한 실증분석이 전제되어야 향후 계획수립시 활용이 가능 할 것이다. 본 연구는 서울시 역세권을 대상으로 다양한 TOD 영향요인을 파악하고, 대중교통 이용수요와 연관성을 규명하기 위한 실증분석을 진행하였다. TOD의 대표적 요소인 Density, Diversity, Accessibility에 대한 자료를 수집하고, 요인분석과 회귀모형을 구축하였다. 분석결과 (1) 요인분석을 토대로 7개 영향요인이 도출되었으며, Factor 1(Diversity/토지이용복합도 (LUM)), Factor 2(Density/개발밀도수준), Factor 3(Accessibility/대중교통시설공급수준), Factor 4(Design/가로설계수준), Factor 5(Green/연계교통시설(보행자, 자전거), Factor 6(Design/지하철시설규모), Factor 7(Accessibility/대중교통운영수준)로 유형화되었다. (2) 요인-회귀분석 결과를 토대로 역세권 승하차 인원에 긍정적(+) 영향을 미치는 주요 요인은 Factor 1(Diversity : 토지이용복합도(LUM) 요인), Factor 3(Accessibility : 대중교통시설공급수준), Factor 2(Density : 개발밀도수준), Factor 5(Design/연계교통시설(보행자, 자전거), Factor 6(지하철시설규모)로 나타났다. 다음으로 역세권의 승하차 인원에 부정적(-) 영향은 Factor 7(Accessibility/대중교통운영수준)로 나타났으며, 가장 높은 영향력을 가지는 것으로 나타났다. 이는 지하철과 버스의 배차간격이 증가할 경우 이용수요가 감소하기 때문이다.

This study aims to analyze the characteristics of the management situation of the Korea Railroad Corporation(KORAIL) through the management innovation process of the KORAIL and to suggest its implications for military application. Despite stable demand, the railway passenger industry had the limitation of not being able to abolish deficit routes due to public service obligations. In addition, the launch of the Suseo High-Speed Line has introduced a competitive system, posing a threat to corporate management. KORAIL wanted to overcome this crisis by innovating its management through the utilization of big data, improvement of the freight business, decentralization of demand, the introduction of tourism railroads, and development of station influence areas. By utilizing big data, KORAIL was able to optimize the railway fare system while reducing fixed costs spent on railway maintenance. It also drastically reduced the station of cargo and created a base station to pursue economies of scale. On the other hand, the existing exclusive station system was abolished to solve the chronic saturation of the downtown area, and the railway demand was moved to Gwangmyeong Station and Suwon Station to optimize the passenger supply. In particular, it developed a new business model called the tourism railway by developing the mountain Byeokjin Line, which was a chronic deficit line, and sought to improve liquidity through the development of the station influence area. Such a process of innovation at KORAIL suggests an appropriate direction in seeking ways to innovate the military medical institutions. First of all, the necessity of improving organizational immersion through the development of a personnel structure suitable for the compulsory organization, while expanding the facilities of the division and corps, and reducing the time required for medical treatment and waiting through the establishment of a data-based medical system was suggested. Next, it was also discussed to integrate the National Health Medical College, which received accreditation as a medical facility through the designation of advanced general hospitals and is ultimately under discussion with the Medical Institution. Through this, we hope that the military medical institutions, which are facing various challenges, will overcome existing limitations and be re-lighted as innovative institution that provides comprehensive public health services.

서울 지하철의 노선 연장, 역사 신설, 운영주체의 변화 등이 예고되는 상황에서 지하철 운영적자의 해소 또는 최소화 방안에 대한 검토가 필요하다. 운영적자와 관련하여 그간 부대사업 수입확충이 대안으로 제시되어 왔으나, 국외 사례처럼 부대사업의 범위를 도시(역세권) 개발로 확장할 수 없는 국내의 여건을 고려할 때 현실적인 대안은 역사 내부 임대시설의 효율적 활용을 통해 수입을 극대화하는 방안이 될 것이다. 이를 위해서는 지하철 역사별로 적정한 임대면적과 임대료 산정이 필요하지만, 관련 연구는 미진한 실정이다. 본 연구는 지하철 5호선과 6호선을 사례로 노선별 특성 및 입지특성을 반영한 적정 임대면적 및 임대료 산정식 도출을 목표로 하였다. 분석결과 지하철 역사 내 임대시설 면적과 임대수입은 지하철의 승 하차 인구수 또는 수입금에 큰 영향을 받았으며, 지상 상권의 영향력은 상대적으로 적은 것으로 나타났다. 특히 노선이 통과하는 지역의 아파트 매매가격의 영향이 큰 것으로 나타났다. 아파트 매매가격이 높은 지역을 통과하는 5호선은 상대적으로 가격이 낮은 6호선 대비 임대면적은 적고 적정 임대료는 높은 것으로 나타났다. 본 연구에서 제시된 산정식은 신규역사 부대시설 도입에 따른 매출액 산정 및 현재 운영 중인 부대 시설 확장방안 고려 시, 보다 현실적인 타당성 검토에 도움을 줄 수 있을 것으로 기대된다.

The Seoul's 2030 Youth-Housing is a policy to promote the development of private sector-built rental housing in a Station Influence Area (SIA). It is a representative policy to resolve a housing problem for the youth in Seoul. The Seoul Metropolitan Government has made continuous policy improvements to respond to earlier criticisms on the policy. In December 2018, the Seoul Metropolitan Government enlarged the possible spatial boundaries of the SIA that the private sector developer can carry out the housing development projects. This study attempts to assess the potential sites available in Seoul by considering the youth's demand. This study used the suitability modelling technique to evaluate the potential sites. In detail, we established three sub-models by reflecting rent, accessibility to living areas of the youth, and accessibility to living SOC for the youth's demand. According to the results, the Hanyang City Wall area, which was newly included by the recent policy revision, showed moderate scores to fit the housing projects, while some Gangbuk areas, which have high accessibility and relatively lower rents, showed the best scores appropriate for the projects. The age group of 20s preferred university districts, while the age group of 30s preferred to locate near Seoul's main office areas. We suggest that the Seoul metropolitan government develops better ways to guage and reflect the demand for differing youth groups and the demand by age groups.

The urban microscale wind field around the air quality monitoring station was investigated in order to check how a building complex influences it. For this study as the high density areas Jwa-dong and Yeonsan-dong monitoring sites in Busan were chosen. As the direction of inflow which is perpendicular to the building of the monitoring station was expected to cause the considerable variation of the wind field, that direction was selected. The model Envi-met was used as the diagnostic numerical model for this study. It is suitable for this investigation because Envi-met has the microscale resolution. After simulating it, on the leeward side around a building complex the decrease of flow velocity and some of vortexes or circulation area were discovered. In addition, on the edge of the top at the building and at the back of the building the upward flow was developed. If the sampling hole of monitoring site were located in this upward flow, it would be under the influence of upward flow from the near street.

The vertical distribution of suspended sediments in the mangrove-mud coast is complicated due to the characterization of cohesive sediment properties, and the influence of hydrodynamic factors. In this study, the time-evolution of suspended sediment concentration (SSC) in water depth is simulated by a one-dimensional model. The model applies in-situ data measured in October 2014 at the outer station in Cu Lao Dung coastal areas, Soc Trang, Vietnam. In the model, parameters which have influence on vertical distribution of SSC include the settling velocity Ws and the diffusion coefficient Kz. The settling velocity depends on the cohesive sediment properties, and the diffusion coefficient depends on the wave-current dynamics. The settling velocity is determined by the settling column experiment in the laboratory, which is a constant of 1.8 × 10^-4 ms^-1. Two hydrodynamic conditions are simulated including a strong current condition and a strong wave condition. Both simulations show that the SSC near the bottom is much higher than ones at the surface due to higher turbulence at the bottom. At the bottom layer, the SSC is strongly influenced by the current.
