Unsatisfactory urban walking environment stresses urban residents, and may cause mental illness and chronic diseases by reducing walking activities. Therefore, establishing a high-quality walking environment that can promote walking activities in urban residents has emerged as an important issue. The walking environment consists of various components, such as trees, stairs, streetlights, benches, signs, fences, and facilities, and it is essential to understand which components and their settings act as satisfiers or dissatisfiers for pedestrians, to create a better quality walking environment. Therefore, this study investigated pedestrian satisfaction and dissatisfaction as a function of various environmental components through a survey using walking environment images. The results revealed that most of the walking environment components except the braille block and treezone exhibited significant correlations with pedestrian satisfaction. Particularly, safety-related component (e.g., adjacent roads, parked cars, traffic cushions, and car separation), and landscape-related components (e.g., trees and green), as well as the material settings of landscape facilities (e.g., wooden fences, benches, stairs, and walkway surfaces) correlated with pedestrian satisfaction. The results of this study can contribute to the extraction of useful features to evaluate pedestrian satisfaction as a function of the walking environment. The research outcome is expected to assist in the effective arrangement of walking environment components and their settings, which will ultimately contribute to significantly satisfactory walking environment and encourage walking activities.

The purpose of this study is to analyze the effect of perceived walking environment around neighborhood on satisfaction for old adults in Daegu. The study was conducted using 407 questionnaires were collected through the survey. The walking environment was categorized into accessibility to neighborhood walking facilities and walking environment around path. Regarding perception of walking accessibility, access to 'public transit stops' and to 'medical facilities' was relatively high. For walking environment, 'pavement condition', 'continuity of sidewalk', and 'slope of sidewalk' were rated relatively high. Multiple regression analysis after factor analysis of walking environment variables showed that religious and convenient facilities, park and leisure facilities, and medical and welfare facilities had a significant effect on satisfaction in walking accessibility. For walking environment the convenience for walking, safety for walking, and amenities for walking had a significant effect on satisfaction. The findings from this study can be used for improving the walking environment for old adults.

본 연구는 보행 활동을 일상보행(utilitarian walking)과 여가보행(leisure walking)으로 구분하고, 보행 유형과 보행 환경 간의 상관관계를 분석하고자 한다. 연구 대상지는 서울특별시 용산구로, 보행환경 측정을 위해 구글 스트리트뷰(Google Street View: GSV)와 의미론적 분할(semantic segmentation) 딥러닝 기법을 활용하여 보행자가 실제로 체감하는 도시 보행환경 요소들을 정량적으로 산출하였다. 일상보행과 여가보행, 인지적 보행환경 만족도를 측정하기 위해 설문조사를 실시하여 192명의 유효 응답을 수집하였고, 설문 응답 데이터를 바탕으로 일상보행, 여가보행, 보행환경 만족도를 시각화하고, 보행친화도 값 간의 상관관계를 분석하였다. 연구 결과, 여가보행과 보행친화도는 유의미한 양의 상관관계를 보였으나(Pearson's r= 0.121, p-value= 0.012), 일상보행과 보행친화도 간에는 유의미한 상관관계가 없었다(Pearson's r= 0.093, p-value= 0.055). 이는 사람들이 일상보행에서는 보행환경보다 이동 효율성을 더 중요하게 고려하지만, 여가보행에서는 보행환경의 질을 고려하여 보행 빈도가 결정된다는 결과를 보여준다. 이러한 결과를 바탕으로 본 연구는 여가보행을 증진시키기 위해 주거지 주변의 보행환경을 개선하는 방안으로, 좁은 보행로에 수직 정원이나 다양한 형태의 입체적 정원을 조성하고, 보도 디자인을 개선하는 등의 구체적인 전략이 필요함을 제시한다. 본 연구 결과는 보행 친화적인 환경 조성을 통해 여가보행을 활성화하고, 궁극적으로 서울시의 지속 가능성과 주민들의 삶의 질을 향상시키는 데 기여할 수 있을 것이다.

Developing reliable measures of the environment is important to increase our understanding of the environmental effects on walking among seniors. As a preliminary study for developing an instrument for measuring walkability of seniors' environment, the purpose of this study are to identify important assessment indicators associated with seniors' walking and to test their reliability using inter-rater and intra-rater reliability methods. A set of assessment indicators was identified through literature review, and field studies by trained raters were conducted in three senior centers located in Seongnam area in order to test reliability of the audit tool. The results indicated high percent agreement for most indicators and overall 91.6% and 86.1% of items assessed had good or medium inter-rater and intra-rater reliability, respectively. The reliable assessment indicators would provide reliable data for use in community-based audits of built environment in relation to walking among older adults. The findings showed that the indicators of aesthetics had lower reliability compare to safety, convenience, and access. Rater training with various images would improve rater agreement while reduce rater bias.

A pedestrian environment provides improved walking conditions and facilities for most pedestrians. However, the walking conditions for women with strollers are poor. The purpose of this study was to provide information on the walking environment planning for women with strollers in an urban housing area through analyse of walking characteristics, patterns of going out, and the psychology of them. This study surveyed 208 women who pushed a baby n a stroller in Gyeongsan. The analysis consisted of calculation of the frequencies, the mean, t-test, and ${\chi}^2$ test. The survey results revealed that, first, the women had their own favorite places in the housing area, and usually went out during the afternoon as various aims. When they went out, they felt stress both psychologically and physically, and they thought that they were weak at walking. Second, the safety and the convenience factors of walking environment were important conditions that make the women to go out often. Third, the environment that have not the accessibility, the amenity, and the diversity also restricted the women from going out with the stroller. As a result, they did mot use the stroller and tended to use their cars to go out. However, when the diversity of the environment is added to walking environment, women invreased their social interactions.

Physical activities in the forest environment stimulate the parasympathetic nervous system of humans and have positive effects on the autonomic nervous system as well as moods and emotions. However, there are almost no studies on the benefits of exercise in the forest environment for patients with myocardial infarction. The aim of this study was to investigate the effects of 15-minute single session walking by myocardial infarction patients in the forest and urban environment on the physiological and psychological states. The heart rate variability was measured in 10 patients with myocardial infarction to assess physiological state after single session walking for 15 minutes in the forest environment and urban environment. In order to evaluate the psychological state, a profile of mood scale (POMS) and semantic differential (SD) questionnaire were used. The results of this study showed that 15-minute single session walking in the forest environment activated the parasympathetic nervous system of adult myocardial infarction patients more than 15 minutes of single session walking in the urban environment, and also made them feel more positive in terms of the POMS and SD. Therefore, this study suggests that even single session walking in the forest environment can positively influence the physiological and psychological states of adult heart disease patients and may also contribute to health care.

The objective of this study was to investigate the perception of walking environment and use of neighborhood facilities of rural female elderly, who are the most susceptible to ambulatory problems. The study showed that parks, senior centers and hospitals were among the most frequently used neighborhood facilities by rural female elderly, while bus stations and senior centers were recognized as the closest facilities. Frequency of use was higher for paid sports facilities rather than parks. Hospitals and health centers were facilities that were desired to be in close proximity. Social support, self-efficacy, and attitude were the factors that affected walking environment. Street trees, accessibility to parks, and street lights were factors that showed a positive relationship with total time of walking activity while perceived crime rate and slopes were perceived as environmental challenges for groups that walked under 150 minutes per week. One factor that negatively affected walking was the lack of sidewalks on streets. Providing parks and walking trails within neighborhood, pleasant walking environments, and safe sidewalks would contribute to improved perception of neighborhood and walking of older rural women.

An unstructured environment requires a robot to possess outstanding mobility and advanced control algorithms since there exist complicated configurations such as obstacle, uneven surface, etc. Especially, when a quadruped robot walks in these environments, obstacles in the walking route will obstruct the walking or may give rise to a serious trouble. In this paper, we introduce a strategy for the stable walking in unstructured environment. The proposed strategy consists of two control algorithms. One is a collision{free algorithm to avoid obstacles and the other is an algorithm to overcome any obstacle. These are based on the obstacle detection method and a shape reconstruction algorithm, Which algorithms are described in detail. In addition, the validity of these algorithms have been demonstrated through experiments using a quadruped walking robot called "MRWALLSPECT III(Multifunctional Robot for Wall inSPECTion version 3 )".
