Due to the paradigm shift of the industrial structure in the contemporary china society, the usage of practical function of industrial facilities goes down in this high developing society, so that it falls into some unused spaces. But the unused industrial facilities that including historical, symbolic and cultural meaning has been creating a new cultural space by giving architectural form and function through a variety of application methods for revitalization design. Especially, the facade design which fully expresses the function and meaning of building while properly expressing the cultural situation. It improves the living and cultural conditions of residents while giving the new symbolism of unused industrial facilities through various ways of application methods for revitalization. The unused industrial facilities that was reconstructed into the exhibition space in Beijing and Shanghai, china since 2006 is the object and scope of this study. The purpose of this study is to analyze the methods and characteristics of application methods for revitalization according to each component of the facade design in the idle industrial facility and to expect it to become basic data in the future design plan of unused industrial facilities.

By operating servers, storage, and networking devices, Data centers consume a lot of power such as cooling facilities, air conditioning facilities, and emergency power facilities. In the United States, The power consumed by data centers accounted for 1.8% of total power consumption in 2004. The data center industry has evolved to a large scale, and the number of large hyper scale data centers is expected to grow in the future. However, as a result of examining the server share of the data center, There is a problem where the server is not used effectively such that the average occupancy rate is only about 15% to 20%. To solve this problem, we propose a Virtual Machine Reallocation research using virtual machine migration function. In this paper, we use meta-heuristic for effective virtual machine reallocation. The virtual machine reallocation problem with the goal of maximizing the idle server was designed and solved through experiments. This study aims to reducing the idle rate of data center servers and reducing power consumption simultaneously by solving problems.

As the importance of economic value of culture has increased, governments have set a strategy to secure national competitiveness through cultural art. One of concrete ways is establishing a cultural space by using idle facilities. This study aims to analyze publicness of Seoul Art Space, suggest ways to improve the facilities of creative space and provide basic date for the further plan of creative space. The object of this study is 8 facilities from Seoul Art Space which is operated by City of Seoul. Through literature review, we extracted 5 elements(each element has 4 sub categories) for publicness(accessibility, openness, convenience, historical connectivity and stay time) and to evaluates publicness of the Seoul Art Space, we analyzed these facilities based on these elements. The results are as follows: The publicness of Seoul Art Space acquired 96.9%(100% is 64 points) for stay time, 95.3% for convenience, 90.6% for accessibility, 73.4% for openness and 62.5% for historical connectivity. For the openness, we suggest to use glass materials and open the space to the public. To improve historical connectivity, we suggest to determine appropriate theme for a particular space or area and set a function of buildings for the differentiation.

As one of a new generation of industries, biotechnology is currently spotlighted, and is creating new research and industrial areas that can be readily combined with information technology. Among them, virtual screening is a method for new drug design which uses computer simulation to virtually design active drug candidates for special disease. In this paper, we present a distributed system for virtual screening, called DVSF(Distributed Virtual Screening Facilities). DVSF is designed and developed to perform virtual screening efficiently on logically distributed idle or strategic resources in a small or medium scale laboratory.

After the Ferry Sewol accident, public interest in marine safety has increased. However, as the marine leisure tourism population increases, the number of casualties caused by marine accidents is increasing, so marine safety education is urgently needed. Since facilities related to marine safety education in Korea are geographically biased to the west, regional imbalances in education are significant. Therefore, this study suggested solutions to the problems of developing educational contents and securing budgets and professionals by using idle facilities of the Korea Institute of Maritime and Fisheries Technology(KIMFT) located in Busan as a maritime safety education center. In addition, as a result of estimating demand using the gravity model, it was estimated that the demand would range from 150,000 to 130,000 per year. This study sufficiently proved social policy validity for policy suggestions using existing idle sites as maritime safety education centers based on objective verification methods and is expected to contribute substantially to policy promotion in the future.

In the past, the rooftop was a place where a water tank was to be installed, and a space of secretion and concealment such as a warehouse exposed in the air. It was because it was judged to hinder the beauty of a city as a whole without having any functional value per se. However, the roof portion is increasingly being utilized for a space such as a cafe, a pub, and a lounge as the rooftop is highly recognized as a place for leisure activities other than an idle space in modern times. Nonetheless, there are no detailed ordinances and criteria corresponding to such circumstances. For example, in case of the rooftop space, the building code applied to the rooftop space is a legal system when the rooftop was an idle space in the past though people have now accessed more increasingly to the rooftop than in the past. This study investigated the definition on the rooftop space evolved in accordance with the change of the rooftop space and the related legal system in Korea, and conducted a survey for the purpose of performing the field investigation for the analysis of physical status in 117 spaces that form the rooftop space in the rooftop of small-scale commercial facilities with 2 stories through 4 stories in Korea and analyze the recognition of users and analyzing the recognition of users. We analyzed the problems in the rooftop space through analysis of derived data, and suggested improvement plans.

Culture and art can be said to be an important medium that enhances people's creativity and satisfies our desire for cultural experience as well as emotional cultivation. These arts and culture are spreading all over the world through Hallyu, etc. to this day, and it is naturally positioned as an industry that creates the highest added value. However, rapid industrialization and development of industrialization also provided many negative causes, such as damage to nature due to the decline of factories and equipment industries, pollution and damage to the surrounding environment due to the use of fossil fuels. Therefore, in this study, we investigated the factors necessary for improving the image of the local community and maximizing tourism classes by actively utilizing the idle space abandoned due to industrialization and industrialization as a complex space for culture and art. As a result, empirical analysis was conducted through a total of six factors excluding typology through factor analysis. The results showed that reliability, certainty, and empathy had a positive effect, but responsiveness did not. In addition, the economic effect was found to have a positive effect on customer satisfaction.
