  • 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 was to examine the effects of home and classroom literacy environments on the reading interests of 104 young children aged 4-5 years old. Their 104 mothers and 52 preschool teachers also participated in this study. The instruments modified and used in this study were the questionnaire which was developed by Fitzgerald(1991), Dickinson, Temple, Hirschler & Smith(1992), and the Primary Pupil Reading Attitude Inventory by Askov & Fischbach(1973). The results of this study were as follows. First, there were significant relationships between children's physical and psychological home literacy environments and reading interests. Second, there were also significant relationships between children's physical and psychological classroom literacy environments and reading interests. Third, home and classroom literacy environments, especially physical environments of home and psychological environments of classrooms, had an influence on children's reading interests. On the basis of this study, enough provision of literacy environments may help to improve children's reading interests, leading to better reading and writing ability.

  • Decommissioning of nuclear facilities should be accomplished by assuring the safety of workers because decommissioning activities of nuclear facilities are under high radioactivity and work difficulty. It is necessary that before decommissioning, the radiation exposure dose of workers has to be evaluated and assessed under the principle of ALARA (as low as reasonably achievable). Furthermore, to improve the proficiency of decommissioning environments, method and system need to be developed. The legacy methods of exposure dose measurement and assessment had the limitations to modify and simulate the exposure dose to workers prior to practical activities because those should be accomplished without changes of working routes under predetermined scenarios. To simulate a lot of decommissioning scenarios, decommissioning environments were designed in virtual reality. To simulate and assess the exposure dose to workers, human model also was designed in virtual environments. These virtual decommissioning environments made it possible to real-time simulate and assess the exposure dose to workers. It can be concluded that this system is able to protect from accidents and enable workers to improve his familiarization about working environments. It is expected that this system can reduce human errors because workers are able to improve the proficiency of hazardous working environments due to virtual training like real decommissioning situations. In the end, the safety during decommissioning of nuclear facilities will be guaranteed under the principle of ALARA.

  • Modeling and Simulation(M&S) technology has been widely used to solve constraints such as time, space, safety, and cost when we implement the same development and test environments as real warfare environments to develop, test, and evaluate weapon systems for the last several decades. The integration and test environments employed for development and test & evaluation are required to provide Live Virtual Construction(LVC) simulation environments for carrying out requirement analysis, design, integration, test and verification. Additionally, they are needed to provide computing environments which are possible to reconfigure computing resources and software components easily according to test configuration changes, and to run legacy software components independently on specific hardware and software environments. In this paper, an Integration Test and Simulation for Engagement Control(ITSEC) bed using a bare-metal virtualization mechanism is proposed to meet the above test and simulation requirements, and it is applied and implemented for an air missile defense system. The engagement simulation experiment results conducted on air and missile defense environments demonstrate that the proposed bed is a sufficiently cost-effective and feasible solution to reconfigure and expand application software and computing resources in accordance with various integration and test environments.

  • The age-friendly environments have the benefits that they provide not only the elderly, but also the disabled, children, pregnant, and young persons with the convenient environments. The study examined how degree the aged perceived their physical living environments were age-friendly. The data were collected from 525 old peoples living in Busan using by the person to person interview. All 34 items related to the age-friendliness of outdoor space and building, traffic, and housing were analyzed. The aged perceived that the agefriendliness of their living environments were mid-range. This implies that the improvements of their physical living environments were needed. The age-friendliness of housing area was the lowest among three areas. This means that the alternatives for improving the old persons' houses were needed. The characteristics which affected the aged' perception of the age-friendliness of physical living environments were economic level, housing type, home-ownership, and health condition.

  • Accurate and efficient monitoring of dynamically changing environments is one of the most important requirements for ubiquitous network environments. Ubiquitous computing provides intelligent environments which are aware of spatial conditions and can provide timely and useful information to users or devices. Also, the growth of embedded systems and wireless communication technology has made it possible for sensor network environments to develop on a large scale and at low-cost. In this paper, we present the design and implementation of a monitoring system that collects, analyzes, and controls the status information of each sensor, following sensor data extracted from each sensor node. The monitoring system adopts Web technology for the implementation of a simple but efficient user interface that allows an operator to visualize any of the processes, elements, or related information in a convenient graphic form.
