Purpose: This study analyzes accessibility of outdoor evacuation places for earthquake and the accessibility improvement effects when expanding the evacuation places in accessibility-deficient areas. In order to consider real-world evacuees, the accessibility analysis is based on service population not on resident population. Method: Location-allocation model as a GIS-based spatial optimization mode is used to analyze accessibility and vulnerable areas to evacuation places. Of location-allocation problem types, 'Maximize Coverage' method is chosen to allocate as many potential evacuees as possible to evacuation places. And impedence cutoffs or evacuation distances (times) are applied to three classes: 500m (7.5 minutes), 1,000m (15 minutes), and 1,500m (22.5 minutes). Case study area is Jung-gu areas, Seoul as a high-density downtown area. Result: Results show that accessibility-deficient areas and population to evacuation places are much more in service population than in resident population. Accessibility is significantly improved when increases when expanding the evacuation places in accessibility-deficient areas. Yet, accessibility-deficient areas are still remained since available lands are insufficient in the high-density downtown area. Conclusion: The study suggests that temporary evacuation facilities like outdoor evacuation places for earthquake need to consider real potential evacuees based not only on resident population but also on service population. Also, policy measures to provide emergency shelters need to more utilize spatial optimization tools like location-allocation model.

This paper examined the changes of urban system through the network and the flow pattern reflected in daily movement in Korea. Because daily movement reflects trip pattern, urban system formed by inter-city linkages can be recognized in terms of living sphere. While population movements between cities have the number of linkage systems of city network and the number of traffic regions composed of the origin and destination has increased respectively. Nevertheless, spatial extent of Capital region and Busan region has been expanded. In Gangwon-do in which Seoul-oriented high-speed transportation network has developed, separation of living sphere between Yeongdong area and the Soyanggang cultural region formed around Chuncheon was intensified. Living sphere that includes Daejeon and the surrounding cities has been expanded to the southern Gyeonggi-do. The existing living sphere formed in Jeollanam-do was fragmented into the east and west around Mokpo and Suncheon due to the weakened centrality of Gwangju. Living spheres formed by spatial interaction were consistent with regional administrative boundary. Considering the increased interaction between Seoul and its surrounding cities, the development of global city-region centered on Seoul is expected.

점포선택에 영향을 미치는 선행변수들을 규명한 기존 연구들은 주로 점포 방문행동에 초점을 두고 진행되어 왔으나, 이러한 점포 방문행동이 과연 실제 구매행동으로까지 이어질 것인가에 대한 연구는 매우 제한적으로 이루어져 왔다. 본 연구에서는 관찰 자료를 이용하여 점포선택의 단계를 점포방문행동과 실제 구매 행동으로 분류한 후, 이들 각 단계에 영향을 미치는 요인들을 탐색적으로 실증하는데 그 목적이 있다. 소매점포를 대상으로 수집된 관찰 자료를 이용하여 분석한 결과, 경쟁점포의 수를 제외한 유동인구, 소매점포의 시계성과 같은 소매점포의 입지요인과 점포의 크기, 가판대 설치, 판촉 행사와 같은 소매점포의 마케팅 요인이 점포방문행동에 유의한 영향을 미치고 있는 것으로 나타났다. 또한 점포방문행동이 실제 구매동향에 미치는 영향력은 주효과뿐만 아니라 상품구색과 같은 점포내부요인과의 상호작용효과가 존재하는 것으로 밝혀졌다. 끝으로 이러한 결과의 이론적 및 실무적 시사점이 논의되고, 연구의 한계점과 미래의 연구방향이 제시되었다.

The advertisement using DID(Digital Information Display) has been a huge increase in many public spaces. Many company has been advertise their products through DID in recent. In this paper, we suggest more effective advertisement system on DID for advertisers. This system can provide a floating population, operation information and other useful I informations for advertisement. The advertisers can choose and buy the advertisement that they want.

본 연구는 국내 현실적인 기준 반영을 위하여 인구 유동에 있어 출퇴근 이용자가 집중되고 상업활동이 복합된 지하상가의 유동인구를 측정하여 재실자 밀도를 분석하였다. 실측 결과, 지하역사의 연결부분은 퇴근 시간을 기점으로 하여 인원이 편중되었으며 상업시설은 11시, 14시, 17시 등 다양한 시간에 이용자가 편중되는 특성을 나타냈다. 아울러 재실자 밀도는 1.52인/$m^2$로 현재 국내 기준과는 달리 다소 높은 분포를 보여주고 있다.

여름철만 되면 폭염 취약계층의 피해 소식이 꾸준히 발생하고 있다. 본 연구는 폭염 취약계층을 예측하기 위한 방법으로 통신사와 공공데이터에서 유동인구데이터, 전기사용량, 온도데이터, 건물 면적, 병원 접근성 등을 활용하여 분석하였다. 디지털 트윈 기법을 활용해 분석결과 높은 온도대비 면적당 전기사용량이 적으며 동시에 유동인구가 많고 병원 접근성이 떨어질수록 폭염 취약계층일 확률이 높을 것으로 예측하였다.
