Automation and robotization has been required in construction for several decades and construction industry has become one of the important research areas in the field of service robotics. Especially in the steel construction, automatic recognition of structural steel members in the stockyard is emphasized. However, since the pose of steel frame in the stockyard is site dependent and also the stockyard is usually in the outdoor environment, it is difficult to determine the pose automatically. This paper adopts the recognition method based on the augmented reality to cope with this problem. Particularly focusing on the light condition of the outdoor environment, we formulated the optimization problem with the constraint and suggested the methodology to evaluate the optimal camera arrangement. From simulation results, sub-optimal solution for the position of the camera can be obtained.

As longevity of human-beings is extended and the population of aged people increases, diverse issues related with the aged people are presented. The neighborhood space for the aged people is required to be designed based upon the understanding of such difficulties of the elderly and the public outdoor environment is an important environmental resource that can enhance the quality of life and promote the health of the elderly in underprivileged area without burdening them economically. This study aims to research the daily life of the elderly in underprivileged urban area and their utilization styles of outdoor environments in order to find out the push factors and pull factors that induce the aged people to use the outdoor environments. For this purpose, this study carried out an interview survey upon 69 elderly residents and surveyed on 363 elderly residents of low income class who are aged 60 and over and living in decaying area in Jeonju. For the analysis of the collected data, a qualitative and a quantitative analysis were accomplished. As results of study, the elderly in underprivileged area use such outdoor environments as resting facilities, exercise equipment, parks, farming gardens and waterfronts, and the push factors for them to use the outdoor environments were sordid indoor spaces, sense of isolation or loneliness, and the desire for maintaining good health. And the pull factors for them to use the outdoor environments were natural factors, opportunities for social interactions, space for exercise. The obstacles that hinder the elderly in using outdoor environments were the bad health of the elderly, lack of facilities, accessibility and weather conditions. Thus, the results of this study are expected to provide basic data for designing the outdoor environments to promote the health of the elderly in urban underprivileged area and to relieve the burdensome problems related with ageing societies.

The purpose of this study is to investigate the change of wind environment for different building arrangement. In this study, we analyze outdoor wind environment on different building arrangement that take same floor area ratio using the CFD (Computational Fluid Dynamics) method. We do not consider the effect of temperature. Building arrangements of low density, different hight and a lot of green area will change the effect of wind environment. The eight different arrangements of buildings are studied in this paper. In these calculations, we know the different arrangement of buildings change outdoor wind environments. Especially, reducing the number of building and crossing the different height of buildings have a good kind of wind environment at the same floor ratio. We know that these arrangement of buildings to reduce the heat island phenomena on city plan.

Public outdoor spatial environment and its convenient facilities are playing an important role in providing space for various student activities in university campus. Previous studies have shown that many socio-demographic-economic students' background and motivation have impacted the level of academic achievement. Moreover, research also contended that school facilities at some points also influenced students' academic performance. Thus, the aim of this research was to investigate the relationship between the level of academic achievement and satisfaction of various spatial environment through survey. For that purpose, one university campus was selected and evaluation indexes were categorized into five major components of physical and experimental environment, later supported by factor analysis. Correlation analysis found that extracted factors were significantly interrelated to academic achievement. Further, regression analysis also explored sense of belonging as major predictor of academic achievement. Finally the study suggested that campus plan be approached carefully, because such experimental environment as diverse club activities at outdoor environment is a key element to academic achievement even though rated low scores in satisfaction.

The analysis of outdoor and indoor spatial composition with natural elements is required for the creation of healing environment in healthcare facility to provide basic data for the planning of hospital architecture. Literature review of healing environment and investigation on characteristics of spatial composition in architectural works and healthcare facilities have been conducted. The spatial composition of outdoor space for refuge and prospect from indoor space of Seoul National University Hospital have been analyzed. The result of this research can be summarized as followed. First of all, the main natural elements for healing environment are consisted with refuge in outdoor space and prospect from indoor space. The second one is that natural elements in Seoul National University Hospital are located in central, posterior, and lateral area of main hospital and connectivity, integration, and ERAM(3) which the characteristics of outdoor spatial composition with space syntax are focused on the museum of medicine and landscape area in the center of hospital. The third one is that the outdoor refuge and prospect from indoor space in Seoul National University Hospital can be replaced with cultural heritage like the site of Kyungmogungji and Changgyeonggung palace in and next to the hospital. In addition to the outdoor and indoor spatial composition, it is necessary to analyze the relationship between elements to develop the healing environment of hospital architecture.

The purpose of this study was to analyze the relationship between outdoor play environments and child's play behaviors. The data were collected by this study included field measurement survey, and non-participatory observation from 8 child care centers in Seoul. The field measurement survey were conducted from February 20 to March 20, 2005, whereas non-participatory behavior observation were conducted from June 15 to July 10, 2005. The major results showed the following. 1) Most of child care centers were too small, did not use the adequate surfacing to play various activities, and were made of play equipment setting. 2) Child's play behavior focused on functional play activity and construction play activity. 3) The relationship between outdoor play environments and child's play behaviors showed that small outside play environment with monotonous construction of play setting produced functional play behaviors on children. However, in some cases, despite the small and monotonous play area, diverse play behaviors were observed. These playgrounds at least differed from others in that they provided the place where multi purpose play was possible. This finding shows that multi purpose play areas can be an alternative in small playground environment.

This study measured indoor and outdoor levels of hydrocarbon volatile organic compounds (VOCs), such as benzene, toluene, ethylbenzene, and xylene isomers (collectively referred to as BTEX), as well as 13 carbonyl compounds, at 20 homes in Seoul, South Korea. Along with the sampling of BTEX and carbonyls, indoor concentrations of the air pollutants nitrogen oxide (NO) and carbon dioxide ($CO_2$) were also measured at each home. These measurements were used to understand the characteristics of BTEX and carbonyls by calculating the various ratios and correlation coefficients between measured contaminant levels. We found that carbonyls were mostly originated from indoor sources, while BTEX were originated from both indoor and outdoor sources. A high correlation between indoor levels of NO and BTEX indicated that traffic emissions were also an important sources of BTEX.

The purpose of this study is to investigate the environmental factors relating to children's outdoor play and to assess how the residential neighborhood is suitable for play in the perception of parents. Based on a citywide survey of 500 parents of elementary school students in grades 1-4 in Seoul, this empirical study shows that children's outdoor play environments in residential neighborhoods of Seoul have been observed to be overall unsuitable for play activity. Three physical environmental factors (spatial availability, neighborhood attractiveness, and street difficulties) and three social environmental factors (fear of crime, social interactions, and psychological comfort) are related to children's play activity. Five factors, with the exception of the psychological comfort factor, impact the suitability of children's outdoor play environment. Specifically, it is the physical environment, rather than the social environment, that was deemed unsuitable in spite of its impacts. These findings help us understand the current conditions of neighborhood play environments associated with children's play activity. It is necessary to improve parents' perceptions of the play environment and children's play activities by improving the physical environment.
