In elderly housing facilities where are elderly living facilities, the importance of outdoor space for psychological healing and stability, health improvement and environmental improvement is increasing, since elderly people suffer from depression and are hostile to these facilities. This study aims to identify if outdoor spaces in elderly housing facilities in Seoul have environments appropriate for the elderly and to suggest problems and improvements. For achieving this purpose, nine elderly housing facilities in Seoul were chosen and a field survey was conducted targeting five facilities with outdoor spaces. Based on the previous studies, the concepts of elderly housing facility and outdoor space were organized. Then, a checklist was drawn up as a framework of analysis for evaluating the present state of outdoor spaces of elderly housing facilities and space planning, and improvements were explored. It was found that elderly housing facilities in Seoul had good connectivity and accessibility to the surrounding areas, but there were few supporting facilities, except for resting places. Also, the result of analysis of the present state showed that most elderly housing facilities were located in high lands and the safety of elderly people was being threatened while moving, due to the absence of handrails. In conclusion, it is considered that outdoor space of elderly housing facility should be planned in consideration of safety, affordance and cognition out of the standards of researcher's evaluation tool.

Purpose: With the increasing of public-use facilities, there has been a growing concern over Indoor Air Quality(IAQ) of public-use facilities. Because the facilities are easy to be exposed to indoor air pollutants, they needs to be periodically managed the IAQ. Methods: In this study, indoor air pollutant concentrations of 24 vulnerable facilities were measured and compared. The measurements were conducted for pollutants which are defined in 'IAQ Control In Public-Use Facilities, etc. Act'. We took two measurements, the first was carried out in summer and the second was proceeded in winter. We analyzed the values according to the type of facilities and pollutants. Results: There was a difference in pollutant concentrations by the season and in occurrence characteristics by the measurement spot. Therefore, we need to manage pollutant concentrations by characteristics of occurrence. Implications: Based on the comparative analysis of pollutant concentrations, we suggested cause and improvement strategies for IAQ management of Vulnerable facilities.

The residential and welfare facilities for the elderly are continuously increasing due to change of value on family under situation of aging population increase. And it is predicted that accommodation capacity of facilities for the elderly and its rate those facilities takes compared to whole social welfare facilities will be accelerated considering past increase speed. On the other hand, about 60% of the elderly have low physical and mental level almost close to disabled people therefore special environmental concerns helping their independent living are necessary. Among them, color application is one of the most important factors for smooth understanding, communication and psychological remedy effect for them. The purpose of this study is to analyze the interior color status in assisted living facilities for the elderly in America which is a leading country in terms of the understanding and policy for the elderly as a part of the research project to suggest the developed solution about the Korean residential welfare facilities for the elderly For this purpose, not only importance and effect of color and visual characteristics and reaction to color in elderly environment but also general concept and policy of the ‘assisted living facility’ in America were researched through documents review. And measuring of color on 5 main spaces such ; lobby/lounge, corridor, dining room, bedroom, stairway/ramp of the 10 facilities in America were performed under analysis of its functional and aesthetic level based on Moon & Spencer's color theory.

After the introduction of Volume-based Waste Fee System for municipal wastes, the disposal of food wastes became an issue in society. As this reason, recycling food wastes facilities play an important role such as converting of food waste into animal feed or composting of food waste. Therefore, there is need of efficiency measurement of the facilities to reduce the inefficiency of factors. The purpose of this paper is to make a reasonable suggestion for the improvement of inefficient recycling food wastes facilities. This paper assesses the relative efficiency of recycling food wastes facilities by examining the relationship between inputs and outputs in 41 facilities using data envelopment analysis(DEA). The result shows that 4 facilities whose values of CCR efficiency are 1, and 10 facilities whose values of BCC efficiency are 1, RTS indicates IRS of 17 facilities and CRS of 6 facilities.

The purpose of this study is to understand the classroom facilities of England and USA in the 19th century. This kind of study can provide the meaning of past, present, and future on classroom facilities. The results of the study are as follows. First, England classroom in the 19th century was made up of a large space, a gallery, that could teach a large number of students at the same time. Second, the classroom facilities of USA in the 19th century were developed by reformers for the purpose of training the labor force of educational thought and industrial development. Third, some characteristics of classroom facilities of England and USA in the 19th century were also found in school facilities of Korea at the same time. Fourth, large gallery classes began to disappear in the mid-19th century and were transformed into small 'class' facilities to improve efficiency. Fifth, the word 'class' did not appear as a substitute for the school, but as a meaning of subdividing within the school. Sixth, these classrooms consisted of smaller classes, and they began to create and teach common and unified curriculums to harmonize the differences between classes and to manage all students efficiently and effectively. Seventh, the basis of the classroom of England and USA in the 19th century was the design of one teacher to efficiently teach a large number of students, and there was a difference in size, but the current classroom facilities have been maintained to some extent. Eighth, since the end of the 19th century, the compulsory education system has been discussed and gradually introduced, requiring more schools and classroom facilities, and labor and capital have been emphasized by the development of industrialization. Ninth, follow-up studies are needed to analyze how classroom facilities have been universally transformed since then, based on class facilities in the 19th century, and what educational, social and political contexts have been added in the process.

The purpose of this study is to survey and analyze the operating state and characteristics of domestic and foreign green care, prioritize the facilities and programs for green care introduction through expert survey of importance, and thereby to provide a basic material for introducing green care in facilities in Rural Development Project districts, including domestic rural experience facilities. Domestic and foreign literature was analyzed in order to classify the necessary facilities programs, of green care, and the analysis results were modified and supplemented through Expert Delphi Survey. Based on the results, AHP based importance survey was conducted. In terms of the facilities and programs for green care introduction, necessary facilities (H/W) were categorized into four types (accommodation facility, resting facility, experience facility, therapy facility) and S/W programs into three types (learning experience type, therapy type, and care type). To verify the reliability of the AHP based importance survey, Consistency Index (C.I.) was analyzed. As a result, the C.I. value of nine respondents ranged from 0.000 to 0.083 so that the survey was found to have high consistency. The importance of S/W programs was 0.627, and that of H/W facilities was 0.373. For green care introduction, programs were found to be more important. Regarding the categories of necessary facilities, therapy facility had the highest value, or 0.348; experience facility 0.253; accommodation facility 0.211; resting facility 0.188. Therefore, therapy facility and experience facility were found to be important. In case of S/W programs, therapy type had the highest value, or 0.499, and learning experience type (0.255) and care type (0.246) were similarly important. Generally, the categories that had high importance values tended to show a remarkable difference in importance of their sub categories. In particular, facilities or therapy programs using natural ecology and forests were found to be highly important. In conclusion, it is required to actively review the introduction of active programs using resources, such as existing experience facilities and accommodation facilities and villages forests, and programs making the body and soul comfortable, such as natural ecology experience, Green Shower, and horticulture activity.

The main topic of this paper is to show a possibility of indoor air quality enhancement and the fan energy savings in underground parking facilities by applying the demand-controlled ventilation (DCV) strategy based on the real-time variation of the traffic load. The established ventilation rate is estimated by considering the passing distance, CO emission rate, idling time of a vehicle, and the floor area of the parking facility. However, they are hard to be integrated into the real-time DCV control. As a solution to this problem, the minimum ventilation rate per a single vehicle is derived in this research based on the actual ventilation data acquired from several existing underground parking facilities. And then its applicability to the DCV based on the real-time variation of the traffic load is verified by simulating the real-time carbon monoxide concentration variation. The energy saving potentials of the proposed DCV strategy is also checked by comparing it with those for the current underground parking facility ventilation systems found in the open literature.

Since urban railway transit is one of the most essential transportation systems, its power facilities must ensure high reliability and safety. Currently, urban railway operating organizations perform TBM (Time Based Maintenance) on power facilities. However, in order to improve management efficiency and system safety, CBM (Condition Based Maintenance) is preferred. Among various power facilities, mold transformers has been chosen as the object of study since it is widely used for the purpose of minimizing volume and weight, and due to safety against fire. In this paper, various transformer failure cases due to electric, thermal, mechanical and environmental factors have been collected and analyzed. In addition, investigation on national and international condition based maintenance cases and the characteristics of sensors widely used for transformer monitoring has been performed to suggest the optimal condition based maintenance technique for urban railway systems.

Based on the concept of Industry 4.0, various sensors are attached to facilities and equipment to collect data in real time and diagnose faults using analyzing techniques. Diagnostic technology continuously monitors faults or performance degradation of facilities and equipment in operation and diagnoses abnormal symptoms to ensure safety and availability through maintenance before failure occurs. In this paper, we propose a model to analyze the data and diagnose the state or failure using machine learning. The diagnosis model is based on a support vector machine (SVM)-based diagnosis model and a self-learning one-class SVM-based diagnostic model. In the future, it is expected that this model can be applied to facilities used in the entire industry by applying the actual data to the diagnostic model proposed in this paper, conducting the experiment, and verifying it through the model performance evaluation index.
