We examine 554 state basic districts and 1832 householders in Busan metropolitan city to see whether the physical and walkable characteristics of housing influence apartment housing prices. We use two-level models modeling for a more accurate analysis. Walkable characteristics in level 2 state basic districts potentially explain 77% of the variation in housing values, with the highest impact on crime safety characteristics. Overall, our spatial multi-level analysis based on new state basic districts in Korea explained price variation better than previous studies, which considered each householder. The results provide policy opportunities for planners and citizen groups to pursue strategies that encourage the development of walkable and sustainable neighborhoods.

경제적인 풍요가 어느정도 이루어지면서 깨끗한 도시환경속에서 삶을 누리고자 하는 욕구도 증가되었다. 이를 반영하듯이 최근들어 환경에 대한 시민들의 관심이 어느때 보다 더욱 커져만 가고 있다. 이와 더불어 도시계획적 흐름도 물적계획에서 비물적계획인 인간중심 위주의 가치관으로 전환되고 있으며, 공원녹지체계의 정립, 도시경관관리방안, 자전거도로의 도입, 보행자도로의 계획과 설계, 대중교통의 활성화 등 많은 환경친화적 프로젝트들이 수행되어져 왔다. 본 연구에서도 기존의 주요 보행자공간으로 다루어져 온 보도공간에 대하여 조사연구하였으며, 도심의 외곽에 위치하고는 있지만 대구시의 남북을 관통하는 주요간선도로변에 접해 있고 보행량에 비해 보도가 지나치게 넓어 비효율적인 토지이용을 보이는 보도공간을 대상으로 하였다. 특히 도심의 외곽지 보도에 관한 연구는 통행량이 많은 도심지의 상업지나 주택지의 보도에 밀려 상대적으로 소홀히 다루어져 왔다. 이 가운데 대표성과 보편성을 가지는 곳으로 선정하여 연구를 수행한 결과 기존의 단순목적 보도공간을 4개의 공간 즉 보행자공간, 자전거도로공간, 차단 및 가로시설공간, 녹지 및 편익공간으로 재구성하였다. 이는 적은 비용과 노력으로 보행의 순기능인 쾌적성과 안전성을 보다 강화시켜나갈 수 있었다. 매연과 소음이 없고 도시민의 건강성를 확보한다는 이유로 여러 선진국에서는 수 년전부터 각광을 받고 있는 것이 보행교통과 자전거교통의 개념인 녹색교통이다. 이러한 녹색교통은 공해감소의 편익도 있지만 무엇보다 매력적인 도시환경의 창출과 인간중심적이라는 가치관에 그 의의가 있겠다.

The Campus Core is centered at the physical, functional and symbolic environment of a university, which is known as the top academic institution, hence it metaphorically represents not only the educational philosophy when institution first opened, but also the transformed values of the time. Today, universities are asked to actively communicate with the local community in terms of function and be remodeled as pedestrian-friendly campuses in terms of physical environment. For this reason, the study comprehends the concept of the campus core in accordance with a pedestrian-friendly environment and suggests a practical plan for campus cores of district national universities based on previous research examination. Since the purpose of the study is to suggest a change in the circulation system centered on vehicle use to transform into a pedestrian-friendly environment through a planned approach while introducing public mixed-use at the same time, the study supports the fact that it is possible to reorganize the strategy of a pedestrian-friendly circulation system and partially revise the land utilization to yield the expected outcomes. Thus, this study will provide valid suggestions for similar maintenance plans while looking back to the meaning and value of today's campus core.

The objective of this study was to derive the served distance of the senior-friendly park considering physical changes, which were estimated through a comparison experiment at an actual target site. The time to walk 500m was examined because 500m is considered the served distance of a neighborhood park and as a standard set by the city. The mean walking time of the control group (younger than 65 years) was 536 seconds, while that of the treatment group (older than 65 years) was 889 seconds, which was approximately 1.7 times longer than the control group. The results of this study also showed that the walking time of females was longer than that of males when they were older than 65 years old. The walking velocities of the control group and the treatment groups were also calculated using the mean walking time. The weight estimated by a proportional formula was 0.6. When it was applied to 500m, which is the served distance of a neighborhood park, the served distance of the senior-friendly park was estimated as 300m. Lastly, the green service excluded area was quantified by applying the 300m, the served distance of a senior-friendly park, to the Jung-gu, Daegu, which had the highest elderly population in the Daegu Metropolitan City. The results of this calculation showed that the area served by a city park was $2,425,747m^2$ and the area excluded from the city park service was $4,627,700m^2$ for senior citizens. The results also showed that, in terms of the distributive equity, the administrative districts received unequal am ounts of urban green area services.

In these days, the frequency in use of senior friendly products including walker, mattress preventing bedsore, etc. is going up by an increase in the elderly population. In the case of the elderly, bad ergonomic design causes some problems in the aspects of usability and safety. In fact, lots of accidents came from using senior friendly products. In this paper, older adults' usability when using senior friendly products was studied through industry-university collaboration. Usability evaluation program was developed to support companies that develop or manufacture a senior-friendly product. Walker and mattress preventing bedsore were evaluated in aspect of its usability and the result were provided to the company.

The purpose of this study is to examine the relationship between children's walking safety or risk of traffic accident and the physical environments around 20 public elementary schools in Changwon-si, Gyeongsangnam-do. Field surveys were conducted to assess the street-level objective and subjective walking environments. The GIS method was used for measuring the neighborhood-level land use patterns. Children's walking safety and risk of traffic accident data were collected from the 6,381 grade 5 to 6 students attending 18 elementary schools through the questionnaire survey. Correlation analysis showed that walking safety and risk of traffic accident of the elementary students were associated with the number of temporary or permanent obstacles on the sidewalk, traffic safety signs, driveway and street intersections, street lights, and percentage of detached housing area and road area on neighbourhood-level. This research will promote to help with constructing a safe routes to school and walking-friendly healthy community.

오늘날 보행 분석은 여러 하지 관절, 뼈 및 근육, 신경 등의 이상을 판단할 수 있는 매우 중요한 지표로 사용되고 있다. 하지만 비정상 보행, 비대칭 보행을 하고 있는 사람들은 자신이 인지 할 수 있을 만큼 그 문제의 정도가 심각하지 않은 상태라면, 그 사실을 모른 채 살아간다. 결국 이런 문제가 지속된다면 향후 큰 질병이 발생하는 요인이 될 수 있다. 본 논문에서는 40개의 압력센서를 내장한 인솔을 통해 각 발의 압력 데이터를 수집하여 미리 정의한 정상 보행 시 나타나는 압력 분포를 기준으로 비정상 보행 여부를 판단하고 보행 시 나타나는 부분별 압력분포 데이터를 이용하여 보행 시 사용자 발의 과내전(over pronation)과 과외전(over supination) 경향도 분석하였다. 스마트 인솔을 사용하여 시간과 공간의 제약이 없는 사용자 친화적이면서 비정상 보행 판단 및 발의 과내 외전 경향 분석에 대해 자가 진단을 보조할 수 있을 것으로 기대한다.

Walk score, walkablity index of built environmental condition, has developed and used in everyday life in United States. The purpose of this study is to produce walk score in Seoul, and to develop computer-based walk score system for improving it's usage. This study covers city of Seoul, and the unit of spatial analysis is 100m × 100m grid cell. This study uses same methodology with walk score in US, the Geographic Information Systems(GIS) is used for calculating the values of walk score(N=58,062). This study implemented Java-based system that utilizes walk score dataset(latitude, longitude, and walk score). This system provided search functions including both lat/long-based and address-based options. Meanwhile, this system was designed to provide the closest value of walk score in dataset if location did not match the certain points in dataset. This study has significance to provide walk score system being easily available to all.

In this research, a way to design a more convenient road for walking by creating more pedestrian space for streets located in busy areas due to many people crowded together was looked into. A symbol or characteristic was given to the street representing the image or regional culture of the area, and effort was given to create convenient yet characteristic street landscape by turning an environmentally sound, open area into pedestrian space. The basic concept of pedestrian space design was taken as the correlations between physical and psychological factors that appear on the environmental aspect of landscape. Areas for which it was difficult to come up with, a method to create a unique open space for pedestrians was looked into by analyzing with other known cases where the pedestrian area landscape was compared with that of the area in question.

본 연구는 주기적인 알츠하이머 병의 중증도 모니터링을 위해 스마트 인솔을 통한 보행 특징 추출과 머신러닝 기반 중증도 분류의 성능에 대해 살펴보았다. 최근 고령화가 가속화되는 추세에 있어 치매 환자가 급증하고 있으며, 중증도가 심해질수록 필요한 치료 비용 및 노력이 급증하기 때문에 조기 진단이 최선의 치료 전략으로 보여진다. 환자 친화적이고 저비용의 관성 측정 장치가 내장된 스마트 인솔만을 사용하여 다양한 보행 실험 패러다임에서 환자의 보행 특징을 추출하고, 이를 알츠하이머 병의 중증도 진단을 위한 머신러닝 기반 분류기를 훈련시켜 성능을 평가한 결과, 숫자세기와 같이 뇌에 부하를 주는 하위 작업이 포함된 복합 보행을 측정한 데이터셋을 사용하여 훈련된 분류 모델이 일반 걷기 데이터셋을 사용한 모델보다 성능이 높게 나타나는 것이 관찰되었다. 본 연구는 안전하고 환경적 제약이 적은 방법을 사용하여 시기 적절한 진단뿐만 아니라 주기적인 중증도 모니터링 시스템의 일환으로 활용될 수 있을 것이다.
