The purpose of this research is to help outdoor space planning reflected real needs of apartment residents in the differentiation elements of outdoor space, by using USC trade-off game in three apartment complexes in Seoul. This game method was used to evaluate their preference, reliability of preference degree, satisfaction degree, requirement elements such as improvement, sacrifice, maintenance of present condition, and payment possibility for improving and maintaining present condition, in addition to their preference and payment possibility of differentiation of outdoor space in the apartment complex in the future. From the statical analysis, we found the following results: 1. Reliability of preference degree was valid, inasmuch as the first elements they preferred were the almost same as the last things. 2. Elements of preference were pedestrian ways, pedestrian security facilities, various athletic facilities, and variety and high-class facilities in a play ground. 3. Satisfaction degree of differentiation elements of outdoor space was low not only in total complexes but also in each complex. As a result of analysis, these elements were not satisfied with residents. 4. Most of the differentiation elements of outdoor space in three apartment complexes, except planting traditional trees, were required to improve and maintain present condition. The cost to improve and maintain these elements able to pay by them was about 2.18 million won. Through this result, these elements were not options but prerequisites for planning outdoor space in apartment complexes. 5. In the future preference elements of differentiation of outdoor space in apartment complexes were pedestrian and jogging ways, places with water, various athletic places and facilities, multi-function resting places, green spaces in experiences, pedestrian security facilities, various athletic facilities, variety and high-class facilities in a play ground, and payment possibility for these elements was about 3.20 million won.

This study aims to investigate determinants that included personal values, pro-environmental beliefs, and proenvironmental norms for enhancing consumers' purchase intention of eco-friendly outdoor wear exploring Stern(2000)’s the value-belief-norm theory. A survey was conducted with females and males between the ages of 20 and 60 who have experienced buying outdoor wear products. A total of 300 responses were analyzed by descriptive analysis, factor analysis, a reliability test, an independent samples t-test, and regression analysis. The results of this study were as follows: 1) The results of exploratory factor analysis and reliability test on the personal value clearly showed factorial structures including the social power, ecologic value, openness, equality, and altruistic value. 2) There are significant differences in personal value sub-dimensions, pro-environmental beliefs, pro-environmental norm, and purchase intention of eco-friendly outdoor wear products according to respondents' gender and age. 3) Personal values, but not social power, affect pro-environmental beliefs; in turn, pro-environmental beliefs affect pro-environmental norms, which then affects purchase intentions of eco-friendly outdoor wear. The findings support the conclusion that there is significant causality among personal value such as ecologic, openness, equality, and altruistic, pro-environmental belief, and pro-environmental norm. This study suggests pragmatic implications to understand outdoor wear consumers' socio-psychological and demographic factors and to augment purchase intentions of eco-friendly outdoor wear products.

Purpose: Since hospitals have a big impact on the natural and social environment, hospitals' sustainability must be considered in various aspects including environmental, social, and economical aspects. So far, research on sustainable hospitals has mainly been conducted on indoor environment, but outdoor space of hospital is as important as well. The purpose of this research is to study the sustainability of hospital outdoor space and to make proposals for improving sustainable regional public hospitals. Methods: Through preceding research analysis and literature review, the concept of sustainable outdoor space of hospital was defined. Also, the evaluation contents of outdoor space were extracted from domestic and foreign green building certification criteria. With this analytic frame, we visited 4 regional public hospitals in Korea, interviewed the facility managers, and analyzed sustainability of hospital outdoor space. Results: Analysis of 4 regional public hospitals reveals that there is a lack of consideration for sustainability in all 4 categories; urban and network, natural environment, community, and user. In terms of community, sustainability has rarely been applied to all four hospitals. The site selection and terrain of the site were essential to sustainability. Implications: Establishing a master plan considering future expansion is critical. Also more attempt to show regional characteristics is needed. It is necessary to design a comprehensive outdoor space that considers sustainability and also healing environment. Level difference in the site can be used as a design element.

Objective: This study aimed to compare gait ability through gait evaluations in indoor and outdoor environments according to the general characteristics and walking ability of stroke patients. Design: Crossed-sectional study. Methods: The subjects of this study were 57 hospitalized stroke patients.The study subjects were asked to select an indoor environment and an outdoor environment in random order, and the Timed Up and Go Test (TUG), 10-Meter Walk Test (10MWT), Figure-Eight Walk Test (F8WT) and the Functional Gait Assessment (FGA) were used to assess each environment. Results: The TUG, 10MWT, F8WT time and number of steps, and FGA showed a significant decrease in gait ability in the outdoor environment compared to the indoor environment (p<0.05). Although the TUG, 10MWT, and the time required for the F8WT were statistically higher in the outdoor compared to the indoor environment at points 2, 3, and 4, but not 5 of the functional ambulatory category (FAC), significant increases in the number of steps of the F8WT were found in the outdoor compared to the indoor environment for only points 2 and 3 of the FAC (p<0.05). In the FAC 3 and 4, there was a statistically significant decrease in the outdoor compared to the indoor environment only in the FGA (p<0.05). Conclusions: Therefore, it has been shown that the gait ability of stroke patients is reduced in the outdoor environment compared to the gait ability in the indoor environment.

Background: Messaging surrounding skin cancer prevention has previously focused on the general public and emphasized how or when activities should be undertaken to reduce solar ultraviolet radiation (UVR) exposure. Generic messages may not be applicable to all settings, and should be tailored to protect unique and/or highly susceptible subpopulations, such as outdoor workers. The primary objective of this study was to develop a set of tailored, practical, harm-reducing sun safety messages that will better support outdoor workers and their employers in reducing the risk of solar UVR exposure and UVR-related occupational illnesses. Methods: We adapted a core set of sun safety messages previously developed for the general population to be more applicable and actionable by outdoor workers and their employers. This study used an integrated knowledge translation approach and a modified Delphi method (which uses a survey-based consensus process) to tailor the established set of sun safety messages for use for outdoor worker populations. Results: The tailored messages were created with a consideration for what is feasible for outdoor workers, and provide users with key facts, recommendations, and tips related to preventing skin cancer, eye damage, and heat stress, specifically when working outdoors. Conclusion: The resulting tailored messages are a set of evidence-based, expert- approved, and stakeholder-workshopped messages that can be used in a variety of work settings as part of an exposure control plan for employers with outdoor workers.

To investigate schemes of secret key generation from Ultra-wideband (UWB) channel, we study a statistical characterization of UWB outdoor channel for a campus playground scenario based on extensive measurements. Moreover, an efficient secret key generation mechanism exploiting multipath relative delay is developed, and verification of this algorithm is conducted in UWB Line-of-sight (LOS) outdoor channels. For the first time, we compare key-mismatch probability of UWB indoor and outdoor environments. Simulation results demonstrate that the number of multipath proportionally affects key generation rate and key-mismatch probability. In comparison to the conventional method using received signal strength (RSS) as a common random source, our mechanism achieves better performance in terms of common secret bit generation. Simultaneously, security analysis indicates that the proposed scheme can still guarantee security even in the sparse outdoor physical environment free of many reflectors.

An efficient urban outdoor localization and navigation system is proposed for car-like robots. First an accurate outdoor localization method is suggested using line/arc features and 2.5D map matching with LRFs (Laser Range Finders), which can reduce the number of singular cases and increase accuracy. Also, path generation, path tracking, and path modification algorithms are proposed for navigation. All these algorithms are implemented on an electric scooter to construct an autonomous urban outdoor localization and navigation system. Experiments reveal the practicality of the proposed system.
