For successful outcome of real estate development projects, it is important to understand the potential tenants as they drive the demand for properties. The aim of this study is to investigate tenant characteristics of the Australian green office building sector. The specific objectives are to; (1) compare and contrast the increment trend of green buildings within the green office building sector; (2) identify the tenancy profile of green buildings; (3) ascertain the possible industry concentrations within the current green building sector; and (4) explore the relationship between green building occupants' characteristics and their tenancy. Descriptive statistics shows that Finance, Insurance and Real Estate (FIRE) industries along with government owned companies are the major tenants of green office buildings in the NSW State of Australia. In particular, real estate companies occupy more than half of the NSW based green office buildings whilst one third of them are the tenants of the 6-star rated buildings - the highest rated building in the current form of Australian Green Star accreditation scheme.

Information system(IS) development projects are mostly unique in terms of the characteristics of projects such as project requirements, customers, project members, and development environment. Therefore, it is very hara by nature, to manage the development process systematically. In addition the long-term enlarged scale projects with more complexity and specificity required have brought in much more risk factors than before. The paper recognized risk factors in IS development projects and measured the importance of those risk factors using the AHP(Analytical Hierarchy Process) method. The results can be used in the risk management of IS development projects.

Organic light emitting transistors (OLET) which are vertically combined with the organic static induction transistor (OSIT) and organic light emitting diode (OLED) are fabricated and the device characteristics are investigated. High luminance modulations by relatively low gate voltages are obtained. In order to realize the flexible electronic circuits and displays, we have fabricated OSIT on plastic substrates. The OSIT fabricated on plastic substrate show almost same characteristics comparing with those of nonflexible OSIT on glass substrate. The OLET described here is a suitable element for flexible sheet displays.

The Comprehensive Rural Village Development Project, a resident-led bottom-up regional development project, began in 2004. This study investigated difficulties and problems in the operation process after the completion of the project, and future improvement plans, through in-depth interviews with the former and current chairman of the steering committee, steering committee members, and office managers, targeting three regions in Jeollanam-do, 15 years after the completion of the project. As a result of the survey and analysis, it was effective in improving the living environment and characteristics of each village and revitalizing the area. And while there were well-run facilities depending on the type of project, there were also many idle facilities. In the case of communal facilities, there was a high possibility of problems in operation and management when the scale of the new building was large. Conflicts occurred between villages in the process of independently operating the area after the completion of the project. Therefore, it is necessary to provide an S/W project program to prepare for after completion. Local governments need to utilize City and County Capacity Enhancement Projects to support regional leaders to participate in educational programs after completion and provide guidance and supervision for village operations.

Recently, the environmental sustainability has showed up one of the important considerations in the construction industry. However, the effective evaluation method for the decision-making on either reconstruction or remodeling of a project has not been developed so far. This paper presents an integrated evaluation model considering both environment and economic factors of a building project for which the decision making on either remodeling or reconstruction is needed. In order to develop the model, the characteristics of both types of projects were investigated and analyzed through the related literature review, and then appropriate evaluation criteria and analysis methodology to be used in the model were developed.

The purpose of this study is to quantitatively analyze the effects of a restoration project on the decrease in the temperature in the surrounding areas. The thermal environment characteristics of the investigation area were analyzed using the meteorological data from the Busanjin Automatic Weather System which is closest to the target area. The terrain data of the modeling domain was constructed using a digital map and the urban spatial information data, and the numerical simulation of the meteorological changes before and after the restoration of the stream was performed using the Envi-met model. The average temperature of the target area in 2016 was $15.2^{\circ}C$ and was higher than that of the suburbs. The monthly mean temperature difference was the highest at $1.1^{\circ}C$ in November and the lowest in June, indicating that the temperatures in the urban areas were high in spring and winter. From the Envi-met modeling results, reductions in temperature due to stream restoration were up to $1.7^{\circ}C$ in winter, and decreased to $3.5^{\circ}C$ in summer. The effect of temperature reduction was seen in the entire region where streams are being restored.

The government has been operating residential improvement projects through the "Act on the Maintenance and Improvement of Urban Areas and Dwelling Conditions for Residents" as a type of a remedial measure for deteriorated residential areas. However, in recent years, the residential improvement projects have experienced difficulties due to the effects of various factors including the slowdown in economic growth. After observing the depression in a number of projects, various studies have been carried out to investigate the causality and improve the promotion of the residential improvement projects. In the trend of research, this study aims to analyze the effects of land and building characteristics on the improvement projects of Busan Metropolitan City. The dependent variables of the study represent different phases of improvement project as specified in the "Act on the Maintenance and Improvement of Urban Areas and Dwelling Conditions for Residents". The independent variables represent land and building characteristics which refer to the criteria used in the designation process of maintenance area according to the act. The empirical analysis uses the ordered logit model. The results from the analysis suggest that geographical condition, factors related to the number of union members, factors related to the parcel price and condition of a location have impact on the promotion of the improvement project. The results of the analysis show that majority of the factors are related to the economic feasibility of the projects. Residential improvement project is a part of urban planning projects that rehabilitates deteriorated residential environment, and it is closely associated with the quality of life of public. Accordingly, we hope that such projects are reasonable and take effective approach to those with urgent needs rather than to focus on profitability. Also, potential administrative and economical loss should be avoided by taking necessary planning measures in advance.

The purpose of this study is to develop a project-based teaching-learning instruction to solve the problems in family life. The developed process can be a practical plan to activate environmental education centered on living environment problems curriculum of Home Economic Education[HEE]. In order to achieve the purpose of this study, the curriculum of HEE and environmental education categories were compared and analyzed. The study selected 10 themes and developed a project-based HEE teaching-learning instruction with 8 sessions. The characteristics of the developed teaching-learning instruction are as follows. First, HEE curriculum included environmental knowledge, values and attitudes, competence, and practice and participation in environmental education and related categories in achievement standards and learning elements. Second, since HEE curriculum has a teaching-learning instruction plan based on project-based learning that allows learners to recognize and solve problems themselves was developed based on the real life-centered learning themes related to environmental education. It was also proposed that the subject of HEE has a high correlation with environmental competence and environmental practice, and thus environmental contents that can raise students' interests in society and environment should be added to the HEE curriculum. The teaching-learning instruction developed in this study can be used for classes such as HEE classes or free semeste. A follow up study would need to test the educational effects of this teaching and learning plan by implementing it to the actual class.

This paper suggested the improvement of marine environmental impact assessment of different types of project by analyzing the consultation on the coastal area utilization(133cases) of the coastal development project for 4years(2010-2013). According to the analysis results, the erosion protection project needs to precede the accurate analysis of erosion reasons, predict exactly possible problems and establish the systematic system to verify the effect of erosion protection by monitoring after projects. The construction projects of revetments and coastal roads have to require to sublate, examine the reliability in structures, give consideration to the problems of coastal erosion by increase of reflected waves. In addition, flooding protection projects have got to require to select the waves for evaluation items in conjunction with the effects of abnormal waves. furthermore, waterfront construction projects need to establish comprehensive and methodical space plans and reinforce the review to conserve the natural environment and conduct nature-friendly development. There are many problems inherently related to coastal development Project. To these problems, however, it is required to support the project on the side of the legislation and conduct additional studies reflecting the characteristics by sea areas and projects.
