This study aims to explore children's perception of, and satisfaction with, outdoor playground within their own residential area. In addition, it aims to provide essential data relevant to the building of outdoor playground for children which will both accord with their biological development and meet their needs. The subjects for this study were 866 children of the 2nd, 4th, and 6th grade living in Taegu Metropolitan City. Data were gathered via questionnaries and analysed by frequencies, percentile, chi-square test, one-way ANOVA, scheff test, and regression analysis. The major findings of the study are as follows; 1. As regards the interest children showed in using the playground, the percentage of those who showed 'no interest' was higher than that of those who showed 'interest', indication that the children did not have a strong interest in using the playground. The older the children were, the lower was their degree of interest. 2. As regards desirable outdoor playground facilities, 'toilet' was considered the most important, followed by 'drinks facilities' and 'sunblinds', indicating that children were not satisfied with existing leisure and rest facilities. 3. As regards the degree to which children's satisfaction with the outdoor playground influenced their overall satisfaction, it was found that the higher their satisfaction was with the different kinds of play facilities, the patterns of play facilities and the layout of the play facilities, the higher was their overall satisfaction with the playground.

Modeling and simulation of human-involved complex systems pose challenges to representing human decision makings into logical systems because of the nondeterministic and dynamic nature of human behaviors. In modeling perspectives, human's activities in systems can increase uncertainty and complexity, because he or she can potentially access all other resources within the system and change the system states. To address all of these human involvements in the system, this research suggests applying the Finite State Automata (FSA)-based formal modeling of human-involved systems that incorporates the ecological concept of affordances to an evacuation simulation, so that human behavioral patterns under urgent and dynamic emergency situations can be considered in the real-time simulation. The proposed simulation methodologies were interpreted using the warehouse fire evacuation simulation to clarify the applicability of the proposed methodology. This research is expected to merge system engineering technologies and human factors, and come out to the new predictive modeling methodology for disaster simulations. This research can be applied to a variety of applications such as building layout designs and building access control systems for emergency situations.

This research surveyed the native resources which BiBo(replenishing shortages by helping each other) landscapes have been preserved by aiming at the village settlement spaces of five cities and counties in Gangwon Youngseo province. This research reveals that BiBo landscape patterns of 41 village forests, 23 BiBo symbols, and 6 BiBo ponds were surveyed. The village forests are all 41 places, and were mainly made on the plains in front of villages. BiBo functions of the forests were in the order of the land obstructing the view of the mouth of a river which is the most as 13 places, the land obstructing the view of the mouth of river, situation complements, village protection, and protection against wind. Bibo symbols were all 23 places. Towers, stone towers, menhirs, and Maitreya stones were 12 places, Jangseungs(a signpost raising on the entrance of the village or a temple) were 6 places, Sotdae(a pole raising at the entrance of the village as the symbol of a board or a village protecting deity) was 1 place, and the others were made multiply in 4 places. Bibo symbols were located at 21 places in front of villages. The village protection in Bibo functions was 6 places. 6 Bibo ponds were surveyed. Most Bibo ponds were made for earth power leakage prevention.

Purpose: Subway in Seoul, Korea is an important urban mass transportation system as it carries more than 4 million people a day. To support this important mission, subway entrances were designed and installed to maximize accessibility to the stations. However, a uniform plan by the national government guided quantity and layout of the subway entrances. Therefore, the plan did not consider unique characteristics of each station area and reorganization of the subway entrance system is required to improve pedestrian environment. Method: This study grouped the subway entrances into specific patterns to propose reorganizing schemes. The authors conducted field surveys, examined case studies and proposed an entrance reorganizing plan for each type. Result: The study recommends subway entrances be installed inside adjacent building when large commercial or office complexes are nearby. The authors proposed installing a bridge connecting the stations and adjacent buildings for elevated entrances. This would be only possible when there are commercial or office facilities nearby with enough floor space. The study summarizes the pros and cons of each solution. To translate our proposals into realities, various incentives should be given to building or land owners. This study made suggestions as to which kinds of incentives exist and be effective in a range of situations.

In a service environment, the spatial layout is an important factor that has a great impact on customers' behavioral characteristics including wayfinding and purchasing. Previous studies have shown a gap between marketing, focusing solely on profitability and satisfaction, and architecture, looking only into efficiency of pedestrian flow. To balance such disparity, this study suggests an integrated approach for assessing behavioral patterns in complex service environments. With the objective that complex service environments should aim to increase its profitability and efficiency while guaranteeing customer satisfaction, quantitative metrics was developed for evaluation. The metrics was defined to use data from behavior observation including path tracking, population counting, and gaze analysis, while previous studies have relied on abstract survey methods that were prone to sampling errors and loss of data. For validation of the metrics in a real world setting, a case study was conducted at 4 train stations in Korea. In the case study, experiments were conducted to gather the required data in all 4 train stations, while their physical layouts were also analyzed. With the results from the case study, comparative evaluation of the 4 train stations in terms of behavioral efficiency was possible, together with a discussion on the effect of their physical settings.

Recently, many urban traditional houses have been replaced by villas and apartments for the inconvenience of lifestyle. The aim of this study is to survey the present distribution condition, research the extension and alteration, focused on Korean urban traditional houses in Cheongju which is the old city in an inland area, and inquire into the behavior patterns of an aged living alone livelihood and a large household. As a result, in the typical 'ㄱ' types of central inland houses, all the rear and side parts are nearly extended except facades facing court, while the detached houses for an aged living alones and tenants have enlarged rooms, kitchen and 'Daecheong' within the existing wooden framework. We could grasp the enlargement of room, 'Daecheong', corridor, and storage in the layout of the existing house. There are so many alterations such as the stand-up kitchen and a water closet. A new extension on an old house was intensely built for tenants.

The fire outbreaking origin of vehicle fire would be classified into two positions such as engine room and passenger room of vehicle. As a firewall is installed between engine room and passenger room, in case of engine fire, it could be assumed that it takes about 10 to 15 minutes for the fire to spread into passenger room There are two different vehicle engine layouts such as transversal and lateral layout, and the fire spreading process and resulting damage patterns on left and right side dash-panel are different depending on the engine layouts. In accordance, the first thing to do for correct and speedy finding of the fire origin place is considered to be an investigation into the dash-panel damage in case of engine room fire investigation.

In this paper, we describe a vision sensor-based driving algorithm for indoor automatic guided vehicles (AGVs) that facilitates a path tracking task using two mono cameras for navigation. One camera is mounted on vehicle to observe the environment and to detect markers in front of the vehicle. The other camera is attached so the view is perpendicular to the floor, which compensates for the distance between the wheels and markers. The angle and distance from the center of the two wheels to the center of marker are also obtained using these two cameras. We propose five movement patterns for AGVs to guarantee smooth performance during path tracking: starting, moving straight, pre-turning, left/right turning, and stopping. This driving algorithm based on two vision sensors gives greater flexibility to AGVs, including easy layout change, autonomy, and even economy. The algorithm was validated in an experiment using a two-wheeled mobile robot.

This work develops a motif design integrated with geometrical patterns in traditional ddeoksal and that can be applied to a scarf design so that traditional elements unique to Korean culture can be developed further for a modern application to various design fields. For the research method, literature reviews on op art and traditional ddeoksal were conducted with Adobe Illustrator CS3 and Adobe Photoshop CS3. As for the motif combination, such applications were taken as five pieces from the works of Victor Vasarely and some traditional ddeoksal shapes such as oblique line pattern, taegeuk pattern, and geometrical pattern. Abstract and geometrical images were borrowed from op art and ddeoksal for image expression. The total number of works selected was eleven. To realize the applied scarf design, a motif layout was performed with the scarf center or rim highlighted so that each design feature could be remarkable based on the motif combination. With the function of scaling, rotation, opacity control, filtering effect, the changed images were shown through motif distortion. In addition, this work applies a single combined motif to products for a possible transformation into handkerchiefs and boutique scarfs in the case of smaller sized scarfs.
