Among various methods to build the construction safety, the consecutive improvement by the measuring and evaluating safety management capabilities for the construction participants such as an owner, a contractor, and a supervisor (construction project manager) can be the effective one. Thus, an effective evaluation and grading criteria to provide performance index for the implementation of safety management activities should be necessary. In this regards, the purpose of this study is to verify the adequacy by offering a competency evaluation system for the supervisor's safety capability and by applying the system to some construction sites. The proposed evaluation system was developed on the basis of the principles of safety management & accident prevention, basic elements of safety and health management system, and safety evaluation cases at home and abroad. The trial evaluation showed that the safety management of the construction site is mainly carried out by the contractor and the supervisor's awareness for the safety management is low on the whole. Especially, it is urgent to improve the support system from the supervisor headquarter and to place the dedicated safety management person in the field.

Lately, with the development of the fields of computer and photogrammetry, Digital Photogrammetric Systems are widely used for the generation of GIS basemap, the acquisition of topographic information and DEM, the formation of digital orthophoto, three-dimensional viewing and so on. According as the demand for the systems is rapidly increasing, we suggest keenly the necessity of domestic technical development, because all of these systems depend on foreign technology until now. In this study, by using digital photogrammetry method, with Visual C++ language, we have developed Digital Photogrammetric Systems for Windows which is able to get three-dimensional coordinates through interior orientation, exterior orientation, epipolar line, image matching from a pair of aerial photos taken with metric camera. This system consists of not only a module which can revise digital map that is being made at National Geographic Institute as a part of data construction project of National Geographic Information System, but also a module which can view three-dimensional image on the screen monitor by using anaglyph for three-dimensional analysis. The digital photogrammetry modules developed in this study are expected to be used as primary modules for the effective management of the urban as well as main modules in developing professional digital photogrammetric systems.

Public institutions guaranteed exclusive position of core business are likely to be inefficient in management. Past governments made various efforts to innovate public institutions. Participatory government drove innovation of public institutions through Ministry of Planning and Budget, and this innovation policy had problems as followings: shortage of common sense of innovation, lack of understanding of innovation, gradual execution of innovation instead of system innovation for business innovation, lack of consideration of characteristics of various public innovation, overlapping of evaluation system, and nonobjective design of evaluation indicator. MB government has diverse assignments for improvement of these problems as followings: transformation of business mind, voluntary participation of employee, improvement of management system of public institutions, reform of business evaluation system, promotion of internal competition, and construction of performance based business system. What is the most important point for successful reform of public institution is to achieve the support of general public with effective action plan and substantial programs.

It is true that SOC facilities, such as dams, need long life cycles since more time has to be invested for the phases of planning, examination, feasibility study, design, contract, construction, and maintenance. This longer life cycle is easily exposed to the risk. And thus, brings additional cost by the delayed project, convenient loss according to the additional run of use, and benefit lose of not to using the facilities. So, the purpose of this study is to try to find a solution to reduce these time consuming problems which could diminish the whole national competition. Hence, this study is to show efficient, systematical project performance and network model by using reciprocal analyses between the construction period and cost based on economical analysis of each phase of life cycles. In addition, on the basis of these outputs, the Fast Track Method is suggested as an alternative solution as a new Approach in Life Cycle's Analysis.

As a part of the ITS, the traffic information system is more widely adopted to deliver traffic information to vehicle drivers via various types of media. As the ITS system establishment has been recognized as somewhat accomplished, the focus has shifted to the efficient operation and maintenance of the system. In this paper, we propose a method for evaluating a VMS traffic information service system from a user's perspective. In particular, relational expressions for the level of information provided and the level of user satisfaction are generated for the evaluation to take place from the user psychological satisfaction aspect of all other beneficial features of the system. As continuous flow facility is the one that has limited entry and exit, the traffic information of VMS plays a significant role for vehicle drivers to make their decisions. A method suggested in this paper could be used for evaluating an existing system as well as setting up the target service level of the system of a new system. If individual system properties are considered along with various VMS functions being as supplement of this research, more systematic evaluation method could be arranged.

It is well-known that inducing learner's spontaneous participation and teacher-student interaction are highly efficient way of teaching and learning. The traditional one-sided, teacher-centered lecture seemed to be inefficient systematically to support the interaction in classroom. Recently, the government was planning to provide the students with Tablet as a part of the informatization project, but it ended up providing only the content of the lecture, not allowing the interaction to occur in classroom. In this paper, we propose a system which aims to support interaction between a teacher and students by utilizing the Web server and Tablet.
