Educational facilities are more uncertain about maintenance costs due to their comprehensive and long life-cycle compared to commercial buildings. In addition, maintenance of the existing post management system can not maintain the original function of education facilities continuously and economically. In order to overcome this problem, it is necessary to analyze the repair and replacement cost for the uncertainty factor in maintenance. This study propose a model to determine repair and maintenance cost and cycle of educational facility based on probabilistic estimation concept. For the analysis, Monte Carlo simulation, a probabilistic analysis method, was applied based on the repair and maintenance history data of the educational facilities in Florida. The results of this study can be used as a guideline for quantitative facility management and facility management research.

Due to COVID-19, the external activities of urban residents have greatly shrunk, causing a lot of damage to the commercial district, such as a decrease in population and sales. The downturn in commercial districts means the collapse of the infrastructure of the national economy, and can have serious side effects on the local economy and individual lives. Therefore, it is necessary to look at the alley commercial area, which is closely related to the national local economy, and pay attention to the damage and stagnation of the alley commercial area where small business owners are concentrated. The purpose of this study is to classify alley commercial districts into growth commercial districts and decline commercial districts by using commercial sales time series data and DTW time series group analysis for the pre- and post-COVID-19 period. The main findings of the study are as follows. First, using the time series data on commercial sales before and after COVID-19, the alley commercial districts were divided into growth commercial districts and decline commercial districts, and it was confirmed that the distribution of growth commercial districts and decline commercial districts was regionally different. Therefore, it is necessary to actively manage commercial districts in areas where many declining commercial districts are distributed, and it is required to prepare policies for each region in consideration of the spatial distribution of declining commercial districts. Second, during the COVID-19 period, face-to-face essential industries, density of guest facilities, and population density negatively affected the sustainability of commercial districts, which is the opposite of previous studies. This is the result of empirically confirming the specificity of the COVID-19 period and the negative effects of the integrated economy, and can be used as basic data for effective commercial district management and policy preparation in the event of a national disaster in the future. Third, the characteristics of the background of the commercial district had a significant effect on the sustainability of the commercial district, and the negative effect of the attracting facilities inducing population concentration in the background area was found. This suggests that it is necessary to consider the characteristics of the background as well as the inside of the commercial district when establishing policies to revitalize the commercial district and support small business owners in a national disaster situation.

This study empirically analyzed the effect of complex commercial facilities on the price of nearby apartments in a Hedonic price model. The spatial range of this study was the walking area of H Department Store located in Pangyo among the second new towns suburb of Seoul, and the time range was 2020. The dependent variable was the real transaction price of the apartment, and independent variable were the characteristics of the housing, the characteristics of the complex, and the characteristics of the region. As a result of the analysis, the area of exclusive use space, the transaction floor, and the highway accessibility had a positive effect on the price of the apartment, and the elapsed year had a negative effect on the price of the apartment. However, the size of the apartment had little effect on apartment prices, and the distance from the complex commercial facilities was shown to be related to apartment prices, indicating that apartment prices declined as it moved away from the complex commercial facilities. Therefore, this is much more influential than the influence of distance from subway stations on apartment price. This confirms that the effect factors of apartment prices and the size of their influence appear differently in the new town area and the existing metropolitan area.

This study investigated to understand the trend of international commercializing technologies and industrial status of the transportation biofuel based on lignocellulosic biomass. Two major commercializing technologies for the lignocellulosic biofuel are biochemical conversion technology and thermochemical conversion technology. It was reported that a total of 93 industrial companies were using lignocellulosic biomass of all facilities related to advanced biofuel. On the basis of commercial type, the biochemical conversion technology was identified to be the major technology in the lignocellulosic biofuel industries, showing 84% of all. Also the main products of commercial type industrial companies are bioethanol (1,155,000 tons/yr) and bio-oil (120,000 tons/yr), which are in a remarkably inadequate amount to substitute for the transportation biofuel worldwide. It was suggested that the transportation biofuel market was currently in need of further development in both technology and scale, and was in high demands of technological development and commercializing exertion.

According to the statistics released by Ministry of Public Safety and Security, the number of restaurant fires in Korea reached around 2,400 and 169 damages of human life and damages to property was approximately over $8.8 billion for recent 3 years. It could be desirable having automatic commercial fire-extinguishing equipment at commercial facilities excluding housing facilities for the safety, applying at the place first where it has been more risky and expected fire can be occurred relatively because economical burden can be accelerated. In order to do this, adjust its level to meet the same level of the kitchen for 'Specific Target for Fire Fighting' that "gas leak alarm" has be equipped relevant regulations and it is considered and reasonable to expand the limit of application gradually.

Children's play facilities have changed over a decade from the traditional play facilities in the front yard to the new type of commercial play facilities which install more exciting and enjoyable facilities, such as Kids Park. The more diversified in the type of facilities, the more difficult in the safety management by the existing system. The 'Safety Management System of Children's Play Facilities' of MOSPA(Ministry of Security and Public Administration) has provided the safety information uni-directly by government sector to the private communities. Recently, multi-directional information sharing methods, such as community mapping are adopted actively in the social activities which have common purpose for making the better community by information sharing with government and private sector. On the purpose of citizen's participation for safe play facilities and preventing accidents, this study investigated the status of child accidents and safety standards, especially focused on the children's play facilities. And the way for sharing safety information among the communities with the GIS mapping skills is suggested in the respect of more easily monitoring and practically inputting the comments on the status of management of play facilities by real users based on their experiences. It is expected that more activities from the private sector would participate to the safety management of children's play facilities by realizing the suggested system.

The purpose of this study is to investigate the actual condition of commercial use of housing site in residential development complexes, and to derive effective future development plan by analyzing the influence of penetrating factors of commercial use. The foJlowing are the results of the analysis. First, characteristics of roads showed that the wider the widths of roads adjoining individual lots have more influences on commercial use penetration. This means that non-residential facilities tend to be located on regions where frequencies of uses are high, preferring regions having good transportation accessibility. Second, characteristics of adjacent usage showed that the distances of common housing, neighborhood facilities, schools to single-detached residential units acted as a factor for higher penetration ratio of commercial use when they were closer.ors an opposite, it showed as distances to parks were further, the penetration ratio were higher. This can be inferred that the condition of detached houses located closer to parks have pleasure environment, and act as a factor preventing commercial use penetration. Third, the official land price presents as a form of quality, as the analysis showed that the higher official land price, the more it acts as a factor increasing the penetration ratio of commercial use.

In order to solve the current shortage of parking spaces, and redesign the main gate area of the U University, the research investigated some cases of other schools located in Seoul which actively constructed multi-purpose building structures. Those schools are considered to be good samples showing their efforts to fulfill the needs of more parking spaces in their campuses, and to cover with the growing needs of multi-functioned facilities accommodating services of academic affairs, reading room spaces, and amenities. With the investigation, the research finded out the current trends of campus developments from the sample schools, such as underground parking facilities connected with multi-purpose buildings along the main arteries of campuses. Following the trends the research thoroughly examined the present conditions of our school and tried to make some possible alternatives for the facilities. Under the conditions, the research suggested 1)to construct underground parking lots accepting around 1,000 cars under the ivory tower square located in front of University Administration Building, 2)to develop a big-scaled open square at the university main gate, and 3)to build a multi-purpose structure along the main street of the campus, which included administration services, studying spaces, and some commercial facilities.

The purpose of this study is to examine and investigate the characteristics of locational facilities and the purchase and leisure patters of residents with its focus on downtown streets of Yeongam-eup which is a eup-level small town. In the subject downtown streets, commercial and residential functions coexisted. While most locational facilities were small-scale sale(buy), food(eat), and employment(public institutions) facilities which were needed for neighborhood life and supporting daily life, the lack of facilities which supported leisure life(enjoy) and represented small town identity was found. The most common frequency of using downtown streets by residents was 'almost everyday'; the most common intention to use was 'to purchase daily things'; and the most common purchase good was 'groceries', followed by farming machines, books, and stationery. It suggested that the use of downtown streets was characterized by daily neighborhood life. In particular, it was found that expensive goods(more than 500,000 won) were commonly purchased in neighboring middle or large cities. Thus, it is necessary to consider the option and professionality of goods. Finally, it is necessary to consider residents' accessibility through reorganizing a street form from car-focused to pedestrian-focused.
