This study examined the building envelope structure used in small housings near urban area which have not good energy source in relation to the application of passive design for energy saving of small-sized architectural design firms in local cities and aimed to provide the basic materials of future design direction of designers and housing owners by analyzing economy of a project in order to know the amount of energy saving and additional expenses depending on the building envelope pattern. As a result of comparing and examining the energy saving cost from the period of use compared to investment by the thickness of insulating materials based on building envelope pattern for energy saving, it was found that the thicker the insulating materials are, the more energy saving amount is. While the current bead-type insulating materials have short payback period due to low initial investment, extruded insulating materials show the difference of five years compared to bead-type insulation because of its high initial investment.

This qualitative research within the project entitled "Multiprofessional Intervention and training for Ongoing Volunteer-based Community Health Programs in the Northeast of Thailand (MITV-NET)" was aimed at explaining changes of health behavior of community people in the Northeast after the intervention. The participants comprised 15 community volunteers and 27 villagers. Data were collected by indepth interview, focus group discussion, participation and non-participation observation, and note taking. Analyses were conducted in parallel with data collection, through content and comparative analysis. It was found that the health behavior fell into 2 categories: easy-to-change. The former involved fun activities joined by community people that improved their health or made them recover from illnesses after a short period without becoming addicted. These activities could be done by themselves, for example, exercising and cooking. The difficult-to-change health behavior is habitual, for example, chewing betel nuts or eating uncooked food. The following factors were found affecting behavioral changes: 1) underlying disease; 2) enjoyment in doing activities; 3) habitual behaviour; 4) improved health in a short period; 5) ability of community leaders and volunteers; and 6) community health-supporting resources. It is suggested that improving people's health requires cooperation of community people through fun activities and some initial external support. People who persist in bad habits should be encouraged to stop by showing them health deteriorating effects.

The Returning Land for Farming to Forestry Project in China is similar to the 'The 10-year National Greening Project' of Korea, and is one of the great strategic policies that started in order to develop the people, resources and the environment by the central government of China. Using the ecosystem recovery as the slogan, The Returning Land for Farming to Forestry Project of China has a long history of 70 years, but the accomplishments has been insignificant when compared to the long history. The Returning Land for Farming to Forestry Project was not a trend due to the societal and economical issues of China, but with the increasing interest on the environmental protection in the late 1990s the extent of the ecosystem is gradually increasing. The most difficult, yet most important matter of the Returning Land for Farming to Forestry Project, is that it must consider the ecosystem with the economy. The farmers want financial gains in a short term, and the government aims is gaining cost-benefit over a long period which is why a rational the Returning Land for Farming to Forestry Project of the central government in China is most important. In order for the Returning Land for Farming to Forestry Project of China to develop further in the future, the standardization and distinction of the economic compensation policy is most urgent. Other than this, a new policy and the government interest on the livelihood of the farmers after the completion of the Returning Land for Farming to Forestry Project are needed, and there must be a clear and fair policy enactment environment so that the opinions of the farmers can influence the policy in the policy enactments.

"Ubiquitous sensor network" definition is this-Someone attaches electro-magnetic tag everything which needs communication between man to man, man to material and material to material(Ubiquitous). By using attached every electro-magnetic tag, someone detects it's native information as well as environmental information such as temperature, humidity, pollution and infiltration information(Sensor). someone connects it realtime network and manage generated information(Network). 21st century's war is joint combined operation connecting with ground, sea and air smoothly in digitalized war field, and is systematic war provided realtime information from sensor to shooter. So, it needs dramatic development on watch reconnaissance, command and control, pinpoint strike etc. Ubiquitous computing and network technologies are essential in national defense to operate 21st century style war. It is possible to use many parts such as USN combined smart dust and sensor network to protect friend unit as well as to watch enemy's deep area by unmanned reconnaissance, wearable computer upgrading soldier's operational ability and combat power dramatically, RFID which can be used material management as well as on time support. Especially, unmanned watch system using USN is core part to transit network centric military service and to get national defense efficiency which overcome the dilemma of national defense person resource reducing, and upgrade guard quality level, and improve combat power by normalizing guardian's bio rhythm. According to the test result of sensor network unmanned watch system, it needs more effort and time to stabilize because of low USN technology maturity and using maturity. In the future, USN unmanned watch system project must be decided the application scope such as application area and starting point by evaluating technology maturity and using maturity. And when you decide application scope, you must consider not only short period goal as cost reduction, soldier decrease and guard power upgrade but also long period goal as advanced defense ability strength. You must build basic infra in advance such as light cable network, frequency allocation and power facility etc. First of all, it must get budget guarantee and driving force for USN unmanned watch system project related to defense policy. You must forwarded the USN project assuming posses of operation skill as procedure, system, standard, training in advance. Operational skill posses is come from step by step application strategy such as test phase, introduction phase, spread phase, stabilization phase and also repeated test application taking example project.

For high-quality software development, it is necessary to detect and fix the defects inserted. If defect management activities are not properly performed, it will lead to the project delay and project failure due to rework. Therefore, organizations need to establish defect management process and institutionalize it. Process standard models handle defect management in the area of project monitoring and control. However, small organizations experience difficulties in implementing and applying defect management process in a real situation. In this paper, we propose a defect management process for small organization which is designed in accordance with the characteristics of a small projects such as few participants and short development period. The proposed defect management process will be based on a tool chain with open source software such as Redmine, Subversion, Maven, Jenkins that support a defect management process and SW Visualization in systematic way. We also proposed a way of constructing defect database and various methods of analyzing and controlling defect data based on it. In an effort to prove the effectiveness of the proposed process, we applied the process and tool chain to a small organization.

The purpose of this research investigates the determinant factors of the joint technology development project performance between SMEs and universities. Reviewing existing papers we could categorize independent variables into three groups of partner characteristics, process management variables and relationship characteristics between partners. Three measures of satisfaction with the cooperation result, the intention of continuing relationship and the utilization of developed technology and product were used as dependent variable considering that we studied the joint projects of SMEs' involvement, short period and small scale. The data was collected by questionnaire survey mailed to the 1082 SMEs and university professors which executed the joint projects sponsored by Small Business Administration in 2009. We received 200 responses from SMEs, and 305 cases from professors among which 55 responses of each partner were on the same project. We analyzed the data sets individually, data of SMEs and that of universities with multiple regression analysis technique and also analyzed the common responses of 55 projects. Analysis results of the data from SMEs indicated that partners' expertise, facilities and equipment, communications, strategic importance, and trust were significant variables for the project performance. Analysis results of the data from universities showed that previous links, definition of objectives, strategic importance, trust and commitment were significant variables. Analysis results of combined data of 55 projects from SMEs and universities indicated that facilities and equipment, project management proficiency and commitment were significant variables.

In order to guide the project for tree seedling production and direct seeding afforestation by introduction of genus Lespedeza, studies were conducted on the effect of seed storage period and on percentage and rate of germination through various kinds of treatments. L. bicolor, L. cyrtobotrya, and L. japonica. intermedia seed were storeds at different period of time. The results obtained are summarized as follows: 1. Germination capacity was not reduced until 28 months after harvest. However, germination was very poor 40 months after harvest, with less than 30% germination obtained by germination treatments. 2. Removal of seed coat and cone, sulphuric acid treatments were more effective in increasing germination than other treatments. Especially, most seeds germinated one week earlier than other treatments by removal of the seed coat. 3. The seeds stored for a short period of time showed more rapid germination compared to seeds which were stored for long period.

This paper summarizes the genealogy of post-war Zainichi magazines in Japan until 1959 and examines their meaning in the context of magazine history in Japan. The purpose of this paper is to prepare the framework to view characteristics of Zainichi magazines in Japan after the war until the present from a continuous and comprehensive perspective. Zainichi, who were left behind in Japan after the war began to project diverse aspects of their lives onto magazines. Despite the poor publishing environment, censorship of GHQ, shortage of writers and financial limitations, the Zainichi society did not give up the public sphere of magazines. The confusion in this time period acted as an element to expose limitations of Zainichi magazines in Japan. Most of magazines published in 1940s and 50s had to focus on political propaganda within the political frame, and many of such magazines were only published for a short term. In other words, it is ambiguous to define the majority of them as 'magazines' and a considerable number of them cannot even confirm the existence, making it difficult to examine the whole picture of magazines from this period. However, recently excavated materials indicate that most of Zainichi magazines in Japan attempted to reflect the reality of the Zainichi society in various ways, though they were confined in the political frame. The process in which language of magazines was changed from Korean language to Japanese and then again to Korean language suggests that Zainichi magazines in Japan tried to consistently express their existence in 'ethnicity,' 'homeland' and beyond, mediated by 'politics' and 'culture.' Moreover, the experience of seeking for the possibility of Zainichi culture in Japan from the flow of cultural movements in Japan during 1950s is an experience of seeking for a popular 'expression' that overcomes the political conflict of homeland. This reveals the diversity the Zainichi society to occur afterwards. A more precise study on individual magazines published during this period would be necessary in the future.

With the barracks modernization project, the Ministry of National Defense has been operating 60 projects of the 75 that have been announced. It was difficult to investigate and analyze the data in the past because data could not be obtained while it was much easier to do that since data can be obtained from private companies. With the aim of increasing the usability of the facilities, the objective of this study is to present a reasonable alternative for repair and maintenance costs by investigating and analyzing the budget and the actual expenses of repair and maintenance of military facilities for the past 3 to 5 years, and then identifying the problems with these. To accomplish this, a theoretical review of previous studies and legal grounds related to repair and maintenance costs was performed, and data on the estimates and the actual expenses data used in BTL projects carried out by private companies were analyzed. First, one of the problems was that there are some items omitted, including consumables, and these items should be included in order to secure their budget. Second, in terms of the items for divided payments, two improvements had been presented: a short-term payment plan for the operation period of 3 to 5 years and a long-term payment plan for an additional and complemented period other than the operation period. The repair and maintenance costs should be further studied at the point of time in a future when the actual data on the costs and operation period of military facilities can be secured. This study is expected to serve as empirical data that will form the basis for a reasonable calculation of the construction cost for military facilities.

This study was conducted to calculate the LCC of a apartment complex with a type of heating system, district heating and cogeneration system. For the purpose of analyzing LCC according to size of apartment complex, 500, 1,500 and 4,000 houses of model apartment selected. This research performs design of heating system and the life cycle cost analysis including an initial cost, energy cost, maintenance and operation cost, replacement cost and renovation cost during the project period(15years). According to the calculated results, 1) Initial cost of cogeneration system with 500, 1500 and 4000 houses is higher than district heating system each of 20%, 13%, 12%. 2) In case of cogeneration system, the payback period by electric generation is 5.21, 4.92 and 4.47 years and saving cost was calculated 29 billion won, 94 billion won and 262 billion won after payback period. 3) Cogeneration system LCC was 1.12, 1.07 and 1.06 times larger than district system with the size of apartment complex. According to the case of this study district heating system is more efficient than cogeneration system in terms of the reduction of LCC. 4) Gas Engine Co-generation System is more efficient than other systems because it can collect progressive part from electric charge progressive stage system. However, the efficiency is decreasing because of raising of fuel bills(LNG) and lowering of power rate for house use. Especially the engine is foreign-made so the cost of maintenance and repair is high and the technical expert is short. 5) District heating is also affected by fuel bills so we should improve energy efficiency through recovering of waste heat(incineration heat, etc.). Also, we should supply district cooling on the pattern of heat using of let the temperature high in winter and low in summer.
