This study tries to suggest a program that the function of a campus can be extended to its community and to be decentralized. This sort of program should be applied to the community without any trouble and be an integration type which the campus members can use actively. To make this possible we observe the activity patterns of the campus members and try to understand the motivation of the activity choice. Finally we deduce the campus activity core. Also, based on understanding the community closed to the campus, we find out what campus can contribute as a community member, not an isolated campus. Through this, the study suggests a program that community and campus devise the growth together as a companion and finally be able to extend its main functions to the community.

In oil-filled equipment such as transformers, partial discharge or local overheating will make insulating material(oil, kraft paper, proclain and wood) be stressed and generate many sort of gases(CO, $CO_2,\;H_2,\;C_2H_4$) which are dissolved in transformer oil. The ratio of this gas can make diagnostic tecchniques of the lifetime of transfomer so, it is important to monitoring $H_2$ gas continuously. This paper developes a system of detecting about $H_2$ gas by using $H_2$ gas sensor, and we describe operation and performance of this system.

The Russian language uses more words that imply collectivism than Western Indo-European languages. In Korean, the first-person plural pronouns are used more often than in Western languages. In this respect, Russian seems to stand closer to the latter, although typologically it belongs to the Indo-European family. The predominance of 'we' over 'I,' which took place in the history of the Russian language, had something to do with the Russian commune and the ecclesiastical and spiritual concept of 'sobornost' (equation omitted). A similarity between the Russian and the Korean nations lies in a collective way of life as compared to Western nations. The Russian concepts of (equation omitted) and (equation omitted) ('commune') have direct analogues in the Korean language. In all societies a commune involves a certain sense of collectivity, or spiritual unity of the people - 'sobornost' (equation omitted). Korean collectivity is more familial and moral in character, whereas Russian 'sobornost' is more spiritual. This has its direct reflection in Korean and Russian languages. One can say that a sort of a family version of Russian 'sobornost' takes place in Korean society.

The purpose of this study is to systematically analyze empirical studies on community facilities of apartment in Korea, to find out research streaming and understand social backgrounds. Since the last year when well-being trend was highly interesting, consumers have showed their concern about not only just interior of house but also exterior environment of their houses. This movement has evoked consumers' interests in level and sort of resident's community space. For this study, content analysis was conducted. Article of three registered academic institute published from 1986 to 2006 were units of analysis. Using keyword through library database systems, the articles were systematically selected. 20 cases were used for data analysis. For this study, content analysis was conducted.

The purpose of this paper is to seek the dwelling conditions for comfortable life like urban apartment with agriculture in farming area. In order to do above things, we divide types of people who is planning to 'return farm' and need to heavily research and analyze current status of use for farm house's each spaces include outside spaces. so this paper aimed that at first, divide types of farmhouse following agriculture condition for people who is living in rural and survey the present condition and problems by analyzing of present status of space use and draw the improvement plans for those. after then, finally make a architectural basic data for Rural houses plan. For the future, the main purpose of this paper is that make architectural provision possible by researching types and size of storage following sort and size of farm.

This paper suggests heuristic algorithm with O(m) linear time complexity for choice of expansion projects that can't be obtain the optimal solution using linear programming until now. This algorithm ascending sort of net profit for all projects. Then, we apply a simple method that deletes the project with minimum net profit until this result satisfies the carried over for n-years more than zero value. While this algorithm using simple rule, not the linear programing fails but the proposed algorithm can be get the optimal solution for experimental data.

Data centers, which implement cloud service, have been faced up with quick growth of energy consumption and low efficiency of energy. 60GHz wireless communication technology, as a new option to data centers, can provide feasible approach to alleviate the problems. Aiming at energy optimization in 60GHz wireless data centers (WDCs), we investigate virtualization technology to assign virtual resources to minimum number of servers, and turn off other servers or adjust them to the state of low power. By comprehensive analysis of wireless data centers, we model virtual network and physical network in WDCs firstly, and propose Virtual Resource Mapping Packing Algorithm (VRMPA) to solve energy management problems. According to VRMPA, we adopt packing algorithm and sort physical resource only once, which improves efficiency of virtual resource allocation. Simulation results show that, under the condition of guaranteeing network load, VPMPA algorithm can achieve better virtual request acceptance rate and higher utilization rate of energy consumption.

Currently, the argument that humanity will eventually reside in some sort of a simulated environment with unlimited resources is actively being discussed in the realm of science and engineering. This paper addresses the issue from the perspective of computer engineering, more specifically in terms of the future gaming environment which is very likely to be brought to us in the form of virtual reality probably in the not-so-distant future. In so doing, Bostrom's simulation argument[1]and Kurzweil's singularity[5] are reviewed, and how our future adobe indistinguishable from our 'real' reality that may be attained by explosive technological advancement relates to the future gaming environment. The problem of human consciousness which is inevitably intertwined with the issue of living in a virtual reality environment is also addressed.

Paper sludge ash was assured as material of a sort of pozzolan. For the reason of fluidity decrease caused by the strong absorption of paper stooge ash and the decrease of compressive strength in case of using over30% replacement by the weight of cement, paper sludge ash is not suitable for blending material. Therefore, it is necessary to find proper replacement ratios between paper sludge and blast furnace slag to insure compressive compensation and appropriate slump. Accordingly, as varied the blending ratios of paper sludge and blast furnace slag, testing mortar was made. This study was aimed to investigate the possibility of using blending replacement of paper sludge ash and blast furnace slag throughout compressive test, flow test, SEM(Scanning Eletron Microscope), MIP(Mercury Intrusion Porosity test), and TG-DTA(Thermal analysis).
