One of the main issues of government is the development of local areas which have been neglected while major capital was invested on Seoul and its satellite cities. Korean Ministry of Construction and Highway and other government departments are currently working together (or the balanced development of the local areas. Localization which is the balanced development of the Capital and local areas, can be achieved through the balanced development of local industry and technology. It is required to have a strategic approach to the construction technology improvement that is localized and eventually contributes the localization efforts. Construction technology that is associated with the local characteristics is the key factor of the balanced national development. This study includes defining the 'localization' through the investigation of national and international localization examples. Construction technology that reflects the local characteristics is studied in this paper. Local characteristics are identified by (1) surveying 'construction technology demand'; (2) measuring construction technology capability, and (3) studying on government regulation changes. 1'he results provide the fundamental Information for the development of the local construction technology.

The procurement of public construction, which has been selected mainly on the basis of the work experience of a department of public agencies that award construction contracts or those in charge of ordering, has not been executed through an objective selection process considering the construction types or characteristics. Thus, as a preliminary study on developing a model for the selection of contract methods, this study intends to analyze and present the key factors affecting the selection of procurement methods in public construction. Through a literature review on the existing methods, foundational factors were first presented, based on the analysis of these factors, the final influence factors were proposed. As a result, 6 factors contractor's characteristics, the environment of the construction market, relevant organization, the characteristics of a project, costs, and responsibility factors were determined, and 14 sub-factors were selected. The factors presented in this study will be used as base data for developing a decision making support model for the selection of contract methods in public construction.

The purpose of this study is to assess the risk and predict the contingency for modular plant construction projects. Considering the work characteristics of the modular plant, The adapted research method is that suggest models for assessment impact of risk and predict the contingency considering risk. Based on the proposed models, It is selected one modular plant construction project and assessment impact of risk factors and predicted the contingency. The results of this study are as follows: Assessment the probability of occurrence of risk factors and intensity of impact, and extract 15 important risk factors. These are classified as Engineering, Procurement, Fabrication, Transportation, Construction phases to consider the work characteristics of the modular plant. The predicted contingency is that 6.739%(Engineering 2.850%, Procurement 6.225%, Fabrication 6.211%, Transportation 4.165%, Construction 8.168%) to prepare the basic business expense. The model is used as a way to derive quantitative results in the decision-making process for risk management in construction projects.

Noise measurements were performed by distance for major construction equipment. especially, For construction equipment that large width of variations is depending on the type of work, noise measurements were performed by the detail type of work. For a time of quiescent and construction, "A" compensation equivalent noise level (Leq) were measured. Most of the construction equipment and the characteristics of the point source appears to be similar in analyzed noise measurement results.

Recently, With the increase of income level, many people desire to have agreeable and quiet surrounding. However, the extent and time of the exposure to construction noise and vibration is increasing, which is a factor that ruins the quietness of the surrounding and increasingly raises interests in its effects. In this point, this study attempts to survey the characteristics of construction vibration by SD(Sand drain) method in construction field. In addition, the result of study is presumed to be usable as the fundamental materials for an efficient counter-plan in case of the public resentment in relations to the construction vibration occurring henceforth.

Recently, with the increasing of construction works, large construction equipment are used to reduce the term of work and labor cost in construction field. Therefore, construction equipment noise has caused much annoyance for a number of dweller in nearby construction field and it has become a very serious problem in our living environment. Neverthless, in our country, adequite guidelines for the construction equipment noise are very deficiency because of the lack of basic data and insufficient research works. From this point of view, this study attempts to survey the characteristics and prediction of piling noise in oil pressure method. On the basis of measurement value, we analysed about prediction possibility of piling noise in oil pressure method.

Scenario-based learning (SBL) has been used in a variety of training situations across different disciplines. Despite its seemly widespread use in construction management discipline, very few attempts have been made to explore its effectiveness and the respective students' learning experience. Using a survey research design, this study aims to investigate students' perceptions on SBL approach in construction management courses. The specific objectives are: (i) to identify the characteristics of a favourable SBL environment, and (ii) to explore the students' learning experience and effectiveness of the SBL approach. The results show that the four characteristics of a favourable SBL environment are: effective team formulation, constant engagement with lecturer, working in a group, and incorporation of motivational incentive for participation. The students really appreciated the opportunities to apply concepts learnt in the lectures in their SBL group work. Also, they perceived that the SBL approach is effective in developing their reflective and critical thinking skills, analytic and problem-solving skills and their ability to work as a team. These findings should facilitate more critical approaches to similar form of teaching methods.

Developable areas nearby metropolitan areas, which has high the density of population are limited by highly industrialized. In recent, the redeveloping plans for the finished industrial and resident areas are pushing to resolve this problems. Getting to the exact properties for reclaimed wastes is very important to reuse of landfill. Also, a strategy for how to deal with follow-up measures have to based on the waste characteristics. A lot of environmental problems have been happened in finished waste landfill such as a nasty smell by seepage, pollution of surface and ground water, a poisonous gas and soil contamination. The environment pollution in waste landfill have been studied by many researchers. The goal of this study is estimate the effects for the ground properties with the environmental properties of waste in finished landfill. As the results, the chemical characteristics of seepage in landfill may effect directly or indirectly to capping layer. Therefore, sustainable researches are needed to develop a secure landfill over the long term.

The need for education that meets the strengths and weaknesses of cyber education is raised because there is difference in the characteristics of students and the needs for education between the cyber university, where the education without constraints of time and space is made, and the existing offline universities. Also, it is expected that the satisfaction of students will be greater if the education is provided based on the analysis of the characteristics of students and their demands for education. There are many students already engaged in construction industry. The students entering the construction engineering department in cyber university are Interested in acquiring the theoretical foundation and professional construction knowledge based on practical experience, professional licenses, and career management. Also, they are interested in further studies at graduate school level and add to academic depth. This study suggests the necessity of establishment of construction education system Including objectives and curriculum in cyber university based on the analysis on the characteristics of students and educational needs.
