Construction projects have become increasingly complex in recent years, resulting in substantial safety hazards and frequent fall accidents. In an attempt to prevent fall accidents, various safety management systems have been developed. These systems have mainly been evaluated qualitatively and subjectively by practitioners or supervisors, and there are few tools that can be used to quantitatively evaluate the performance of safety management systems. We propose an expertise-based safety performance evaluation model (EXSPEM), which integrates a fuzzy approach-based analytic hierarchy process and a regression approach. The proposed model uses S-shaped curves to represent the degree of contribution by subjective expertise and is verified by a genetic algorithm. To illustrate its practical application, EXSPEM was applied to evaluate the safety performance of a newly developed real-time mobile detector monitoring system. It is expected that this model will be a helpful tool for systematically evaluating the application of a robust safety control and management system in a complex construction environment.

A basis for the direct use of data from nondestructive evaluation methods in bridge management systems is presented. Bridge management systems use integer-valued condition ratings to recognize conditions of bridge elements, to model progression of deterioration, and to determine repair needs. Data from nondestructive evaluation methods can inform management systems on the extent of damage, on the initiation of deterioration processes, and on the exposure of bridge elements to aggressive agents. In addition, data obtained through nondestructive evaluation methods allow the formation of models of specific deterioration process. The use of these data in bridge management systems requires redefinition of condition ratings together with the creation of procedures for automated interpretation of data. By these action, nondestructive evaluation methods are directly used to assign condition ratings, and condition ratings are made into terse form of NDE data that are compatible with present day bridge management systems. This paper reports work in progress to strategic use of nondestructive evaluation methods in bridge management system.

Performance measurement is not an easy task. However, it is necessary to measure the expected value of the informatization project to be invested, to help the successful progress of the informatization project, and to confirm the result of the informatization project. This study describes the evaluation systems of the defense informatization project in Korea used after the end of the informatization project (post-implementation evaluation stage). In the post-implementation evaluation stage of proposed system, the informatization project is evaluated in terms of performance achievement, project plan compliance, project management, and economic validity. For each element, this study suggests metrics and practical measurement method. With metrics and their method, it can be evaluated which project is better than others. Moreover, the lessons learned can be developed. Under scarce budget condition, defense organizations can make better performance from IT project with the evaluation system suggested in this study.

National forests have been assumed to do a leading role in carbon sequestration and creating forest resources since society demanded it due to climate change. Therefore, it is needed to check whether a national forest management plan and its evaluation are implemented effectively. As an effective planning and management is to be ensured on the basis of proper evaluation system, this research suggests to improve the evaluation system by analyzing it theoretically. Improvements for national forest management plan and its evaluation are as follows: (1) adjusting evaluation goal and time; (2) giving weighting to each work when planning; (3) writing details of change in planning and its grounds; (4) using the national forest management information systems to integrate these evaluation methods and result. Since to predict future changes in forests and achieve sustainable forest management begins at the reliable evaluation for overall process of the implemented project, the significance of this study is in proposing the improvement of evaluation system for national forest.

Success in Knowledge Management depends critically on the evaluation system that managers of an organization evaluate objectively performance of members of the organization. In particular, the differences in the standard of Performance evaluation used by managers in Governmental Institution or Agency of make an issue of the standardization of Performance evaluation. Therefore, in this paper we propose the alternative evaluation method, which minimizes the bias resulted from the different standards by measuring ranking of knowledge workers, instead of quantitative analysis, using Median Rank method in Reliability and verify our proposition using the analysis of examples.

This Paper examines analytic studies of the evaluation system used for evaluating government-supported R&D Institutes (GSRIs), and designs a new model for analyzing the evaluation system's effectiveness. The analytic models in existing studies use the meta evaluation and balanced scorecard (BSC) models. However, theses studies focused on the structure and elements of the evaluation system for examples, the appropriateness of the elements within the evaluation system and the balance of the evaluation index. Accordingly, the effectiveness of the GSRI evaluation system, that is, the evaluation's influence on GSRI performance improvement was not analyzed. This study uses the institution theory and contingency theory perspectives as related to government organization management to develop an analytical model of GSRI evaluation system effectiveness. The new model proposes an analytical approach for improving the effectiveness of the GSRI evaluation system in an institutionalized environment.

A high-speed railway system represents a typical example of large-scale multi-disciplinary system, consisting of subsystems such as rolling-stock, electrical hardware, electronics, control, information, communication, civil technology etc. The system design and acquisition data of the large-scale system must be the subject under strict configuration control and management. Systems engineering technology development project for Korea next generation High-speed Electric Multiple Unit (HEMU) system in progress is a national large system development project that is not only a large-size and complex but also multi-disciplinary in nature. Therefore, all stakeholders must understand and share the functional and performance requirements of HEMU throughout its life-cycle phases. Also in the test and evaluation phase, all systems requirements must be verified. In 2011, the prototype train manufacturing will be completed. It will do test run on the commercial line and all systems requirements are verified until 2012. For the system verification, the test and evaluation process have to be established before the test trial run. Using a systems engineering tool, the system design database(SDD) with requirements traceability and development process management in the course of the development have to be established. This paper represents the test and evaluation process development based on the SEMP(Systems Engineering Management Plan) developed in the design stage. The test and evaluation process is refined and updated in comparison to the design stage one. The test and evaluation process consists of procedure, test and evaluation method and schedule. So through this process, it is defined that each systems requirements is verified on which test and about what time.

Despite the increasing interest in web contents and the rapid growth of CMS(Content Management System) market, the studies on the evaluation criteria for determining the purchase of the CMS solution are very rare. We introduce previous researches on the evaluation models of IT solution, and develop new criteria for evaluating CMS solutions. We calculate the relative importance of the evaluation criteria using scores from the IT experts based on the "Pair-wise Comparison" using the AHP. Based on the analyses of IT specialists′ responses, the results of the study show that, among the ten criteria, "the function of content management", "the contribution to the company′s business process" and "the fit with Information Strategic Plan" are the three most important ones over the remaining others. The developed model and criteria for the evaluation of the CMS solutions are expected to contribute on effective purchasing decision of the solutions and their successful implementation.
