This study was conducted to develop a system that processes harmful gases and dust, which being generated in the production of micro-inorganic fabric. This can be obtained by melt spinning raw materials such as agalmatolite, fluorspar, limestone, silica under high temperature at $1500-1600^{\circ}C$ in a glass recuperator using a dry method by Cyclone Reactor or Envelope Type (ET) type Bag Filter. If the number of the members of Korea Glass Industry Association reaches up to 45, the damage of the harmful gas being generated in recuperator should not be small. In addition, research of existing facilities showed the most of harmful gas treatment facilities which adopt wet treatment or semi-dry treatment process. This was caused the problems for wastewater and the second pollutive materials. Moreover, in the dust collecting facility behind recuperator, it is also problematic that electric dust collector requires enormous initial investment. We have researched various methods to show both economic and efficient new processes for the preventive facilities of recuperator. As the result of the experiments, the removal efficiencies of HF and SOx were 99% and 87%, respectively. Although it was insignificant reaction, a pretty much interesting result that NOx showed an absorption reaction with $Ca(OH)_2$(removal efficiency was more than 25%) was obtained.

A new movement in forming community villages for better living standards is becoming popular. In order to sustain a proper community, it is essential to design proper community programs and facilities, which can encourage the proactive participation of residents. In this study, detailed aspects of the Mindlre (Dandelion) community (including formation process and management of the village) are investigated. The Mindlre community is a successful community village in Korea concerned with residents' participation and community activities. The community is located in Sancheong, Gyungsangnamdo province in Korea. The study methods are references, field trips, and interviews with residents. Six areas were surveyed and investigated: the physical environment of the Mindlre community and eco-friendly elements, respondents' background and the motivation to join, residents composition, residents' participation in the formation process of the community, self-management systems and common activities, and residents's life satisfaction. The mindlre Community was founded on Christian religions faith. The primary idea of this village was building a new hope for rural areas without discrimination. The size of the village was expanded with housing for teachers and students who were linked with the Mindlre School (substitution school). When the community was founded, existing shapes of the village were preserved. The village was physically renovated based on the original environment, in addition nature friendly materials and methods were used. The residents were proactively involved in the community through regular meetings, self-regulation, and community worship. Although the survey results should that most residents were highly satisfied with living standards, there seemed to be no clear division between community facilities and private houses. A systematic and detailed space planning technique was required. In addition, various community facilities are required due to the expansion of the community.

The purpose of this study is to measure the change in evacuation time at high schools according to the change in hallway width using an evacuation simulation program and to analyze the result of such change. In order to measure the evacuation time according to the change in the hallway width according to the 「Rules on the Standards for Evacuation and Fire Protection Structures of Buildings」 and to analyze the change in evacuation time resulted from the increase in the number of occupants, a scenario was constructed by applying the 「performance-oriented design method and standard for firefighting facilities, etc.」. As a result of the experiment, it was found that the evacuation time was the shortest when the width of the hallway was the widest, which was 3m. On the other hand, the evacuation time took the longest at 1.8m, which was the width of the second narrowest hallway. For the safety of high school students who spend a lot of time at school, it is necessary to secure a wide hallway width when building a new school or to provide periodic safety education in the case of an existing school whose hallways are considered narrow.

본 연구는 대구광역시의 고등학교 분포 특성을 구(區)별로 고찰하여 공간 불균등 실태를 분석하고 그에 따른 문제점 및 장래의 교육시설 입지와 관련한 정책적 대안을 제시하고자 하였다. 교육시설의 지역간 질적인 차이는 고려하지 않았고 다만 양적 측면의 분석이다. 2000년 말 현재 대구시에는 76개의 고등학교가 운영중인데 설립 주체에 따라서는 국 공립 고등학교보다 사립 고등학교가, 운영 유형에 따라서는 실업계보다 일반계 고등학교가 수적으로 우세하다. 전체적으로 대구시의 학교시설 분포는 인구분포(재분포)와 밀접히 연관되어 있는데, 고등학교 교육시설의 수요와 중급간에 구별로 심한 불균형을 나타내고 있다. 학교시설의 지역불균등은 인구이동과 더불어 학교의 이전과 신설에 의해 그 정도가 심화되어 진다. 학교 미전의 경우 구간(區間) 이전은 도시 기능과 인구재분포가 주원인이며, 구내(區內)이동은 토지이용에 대한 민간부문의 개발압력이 학교의 이전을 촉진시키고 있다. 학교의 신설은 최근으로 올수록 민간부문(사립학교)보다 공공부문(국 공립학교)에 의해 공급되어지는 경향이 있는데, 학교의 이전 혹은 신설 대상지의 선정과 과정에서 특정지역을 선호하거나 기피하게 되고 결국은 이것이 교육기회의 공간불균등을 초래하게 된다. 결론적으로 교육시설은 공공서비스 중에서도 주민복지의 증진이라는 최종목표는 물론이고 이용자의 편리성을 고려한 사회적 형평성이 중요한 실천목표가 되어야 한다. 이런 점에서 볼 때 학교 시설의 신설과 재분포는 더욱 활성화되어야 하며 특히 민간부문보다는 공공부문의 역할이 중요하다.

Purpose: This study proposes a process for evaluating the preventive maintenance policy for a system with degradation characteristics and for calculating the appropriate preventive maintenance cycle using time- and condition-based maintenance. Methods: First, the collected data is divided into the maintenance history lifetime and degradation lifetime, and analysis datasets are extracted through preprocessing. Particle filter algorithm is used to estimate the degradation lifetime from analysis datasets and prior information is obtained using LSE. The suitability and cost of the existing preventive maintenance policy are each evaluated based on the degradation lifetime and by using a minimum repair block replacement model of time-based maintenance. Results: The process is applied to the degradation of the reverse osmosis (RO) membrane in a seawater reverse osmosis (SWRO) plant to evaluate the existing preventive maintenance policy. Conclusion: This method can be used for facilities or systems that undergo degradation, which can be evaluated in terms of cost and time. The method is expected to be used in decision-making for devising the optimal preventive maintenance policy.

This study aimed to verify the validity of the evaluation items and weight determination of the indoor environmental safety area, which has the most frequent accidents, among the safety certification evaluations of educational facilities by the Ministry of Education of the Republic of Korea, which has been conducted since May 2021. As a preceding study, the evaluation items of the school safety evaluation checklist being implemented in the US state of Vermont were compared, and the causes of accidents judged by teachers in the accident experiences written by 200 Korean teachers were compared with the safety certification evaluation items belonged to the Ministry of Education. In addition, research literature using the AHP analysis technique on safety risks of elementary and secondary schools in China and safety evaluation index study cases of 539 elementary school children in Indonesia were analyzed. Through these preceding studies, measures to add and adjust evaluation items were derived and the validity and importance rankings of evaluation items were calculated through AHP questionnaires to teachers and safety experts. In addition, a survey was conducted on 104 ordinary people to verify the results of expert analysis. As a result of expert AHP analysis, 'safety education and disaster response training (.396)' was the highest priority for the relative importance of the first layer, followed by 'safety measures (.387)' and 'building materials'. Safety (.216)' was found to be the highest priority. In the overall importance ranking of the 13 second-tier screening items, safety accident prevention education had the highest priority and disaster preparedness training ranked second, proving that the Ministry of Education's review weight was underestimated. In addition, slip and collision accident countermeasures, which were not in the existing Ministry of Education review items, ranked 4th, laboratory practice room safety measures ranked 6th, and sanitation, cleanliness, hazardous substance management, and cafeteria/cooking room safety measures ranked 9th, indicating a significant level of importance. Referring to the importance ranking, which is the result of this study, it is suggested that it is necessary to review the weight of each review item again.

A Considerable number of middle and high schools has an educational program that allows the students to move from one class to another according to their academic achievements. It is, however, performed in existing classrooms with uniform pattern, corresponding to the launch of the 7th curriculum (scheduled to practice in 2000). This research is to investigate the current situation of IILA and to collect the teachers opinions and their demands regarding spatial change to accommodate IILA effectively. This research is also to acquire a fundamental data to set up a prototype for designing a school building for IILA in future. The research process includes surveying the current circumstances of IILA in 136 middle and high schools in Seoul and Pusan, and performing interviews for 9 schools. The research results revealed that there was lack of classrooms to comply IILA in most cases and inconvenience resulted in moving from class to class. It also showed that majority of students experienced unhandy due to limited lockers for the personal belongings. It is also found that the IILA was not a practice for offering various teaching methods but simply an aspect of grouping students based upon their academic achievements.
