The purpose of this study is to predict remodeling timing of Permanent Rental Housing through historic data and cash flow analysis. For this aim, the study has estimated cash flow of Permanent Rental Housing considering initial construction costs, government supporting fund, rental incomes and maintenance expenses. Based on the expected cash flow analysis, reasonable remodeling timing is predicted for Permanent Rental Housing. The results of this study are as follows: (1) it is analyzed that building a8e of about 27 years is the best time for remodeling because cumulative surplus amounts reach maximum level, (2) it is required that remodeling should be made before 34 years of age roughly because cumulative surplus amounts change into minus from this time.

Since the cut slope has been big concern due to frequent failures, the government decided to include cut slopes in the“Act for Safety Control of Public Structures”. Based on the Act, the cut slope whose height is over 50m and length is over 200m should be inspected on the regular basis. According to the Act, KISTEC developed the objective evaluation method for the condition of cut slope. The evaluation method is divided into two categories: evaluation for damaged condition and evaluation for failure affecting factor. Based on the evaluation results, the cut slope is graded from A to E. In this study, the process to evaluate the cut slope condition and the evaluation criteria to divide the grade of cut slope are introduced.

The railway safety in Koreaisthreatenedduetotherestructuring of the railway industries, introduction of the Korea Train eXpress (KTX) and electrification of the conventional lines. Many technical backgrounds are required to control railway accidents as low as reasonably practicable, such as a railway safety act, safety standards, and safety assessment infrastructures. Korean government and the Korea Railroad Research Institute (KRRI) are conducting an integrated R&D program for improvement of the railway safety, where the target is to reduce the accident fatalities by half. The program is composed of three parts; the safety system engineering and the program management, the establishment of a safety management system, and the development of techniques for assessing and preventing major railway accidents. Details of the research programs are explained in this paper, where risk is used as the major control measure.

Purpose: Forecasting of petroleum consumption is useful in planning and management of petroleum production and control of air pollution. Research Design, Data and Methodology: ARMA models, sometimes called Box-Jenkins models after the iterative Box-Jenkins methodology usually used to estimate them, are typically applied to auto correlated time series data. Results: Petroleum consumption modeling plays a role key in big urban air pollution planning and management. In this study three models as, MLFF, MLFF with GARCH (1,1) and ARMA(1,1), have been investigated to model the petroleum consumption forecasts. Certain standard statistical parameters were used to evaluate the performance of the models developed in this study. Based upon the results obtained in this study and the consequent comparative analysis, it has been found that the MLFF with GARCH (1,1) have better forecasting results.. Conclusions: Survey of data reveals that deposit of government policies in recent yeas, petroleum consumption rises in Tehran and unfortunately more petroleum use causes to air pollution and bad environmental problems.

The development of IT has contributed a lot to enhancing administrative efficiency. In particular, it enabled administrative agencies to be able to upgrade the effects and efficiency of public services by saving unnecessary time, labor, and equipment that might surely occur in delivering routine services in repetition. As the concept of governance and knowledge-based administration assumes a pivotal value in the 21 century administrative innovation, sharing information among agencies is a key to building effective governance system. However, current extent of sharing information in public agencies is below the level of expectation and thus the need exists for the steps to making information shared more widely and effectively among public agencies. This paper gives a snap shot on the extant status of information sharing among public agencies and seeks ways to facilitate it from the perspective of electrical government.

Information System (IS) Success Model proposed by DeLone and McLean is applied as a successful operation tool of information system, with its basic assumption of symmetric relationship between independent variables and dependent variables of the structural equation modeling. However, because previous studies have proved asymmetry of quality factors' influence structure on dependent variable by applying three-factor analysis, this study examined asymmetry of impact structure of quality factors introduced in IS Success Model on user satisfaction. Also the study applies structure equation modeling (SEM), three-factor analysis and importance and performance analysis (IPA) to develop resource allocation strategy for IS success. The study is able to provide IS practitioners with strategic implications for allocating and managing limited resources more effectively.

Administrative procedures are the heart of the activity in each Town Council. Citizens do transactions every day and, sometimes, they do not understand what they must do or the steps to follow. We are developing a Web-based system to help citizens with this task in an easy way. The application is integrated a four year project called Albacete[Digital] that began in 2002 with the purpose of building an e-government system in Albacete, a city with over 150.000 citizens. This Administrative Information Centre is the result of the Administration study in the first year of the project and it will continue with the on-line transaction in the following years.

For the selection of attraction industry of foreign investment in the free trade zone of Gwang Yang Bay, an overall consideration should be made considering aspects such as the industry development strategy of Gwang Yang Bay and the regional industry development strategy of the local government. For Gwang Yang Bay to grown into the E-Hub Port of Northeast Asia, the development of the back zone of should be accelerated. There is a need to offer custom made incentives for the core businesses. Packaging is a field of combined science and a future industry. Packaging industry, which has close association with regional industry and regional college's research human resources, should be combined with design and set up a packaging industry complex.

The university mathematics education has been in a crisis during the last 10 years. In recent years, the crisis is rapidly amplified with a science-engineering student resource downsizing. In korea, government and industry have intervent several supporting policies to treat the mathematics-science-engineering crisis in university education. In this article, policies and its contents about human reasource development, industry-university co-ops, national skills standards are presented in context of university mathematics education.
