The purpose of this study was to evaluate the change of chemistry-related attitude of preliminary teachers, after the project of examining chemists contributing to the quality of human life. One group pretest-posttest was used in this study as an experimental design. Before examining the chemist, few preliminary teachers have the knowledge about the chemist contributing to the quality of human life. After the project of examining the chemist, the affirmative awareness on the chemist on preliminary teachers is increased. This result shows that the project of examining the chemist contributing to quality of life can give to make the positive attitude of preliminary teachers on chemistry, and to apply the useful tool related to STS curriculum which is not described effectively in science or chemistry textbook.

The first high speed railway in Korea was opened to traffic on April 1, 2004 and the second phase will be opened on November 1. 2010. Many technical problems that occurred during construction have been solved. In its early period of project, difficulties were encountered in design, construction of high speed line. because most of Korean railway engineers were familiar only with conventional railway. Now they understand the various phenomena occuring during operation of the KTX and have accumulated extensive technical knowhow. Valuable experiences and knowledges that have been obtained from frials and errors will lead to further improvement for the future project.

We focus on discrete event systems with a structure of parallel processing, synchronization, and no-concurrency. We use max-plus algebra, which is an effective approach for controller design for this type of system, for modeling and formulation. Since a typical feature of this type of system is that the initial schedule is frequently changed due to unpredictable disturbances, we use a simple model and numerical examples to examine the possibility of applying the concepts of the feeding buffer and the project buffer of critical chain project management (CCPM) on max-plus linear discrete event systems in order to control the occurrence of an undesirable state change. The application of a CCPM-based framework on a max-plus linear discrete event system was proven to be effective.

This study attempts to provide an efficient method for managing the Nuclear R&D projects. It should be noted that the technology and experiences to develop a well-balanced plan and mon-itoring for the R&D project are not yet well established when compared with the commercial con-structionand engineering projects. This study recommends that the R&D project manager utilize the scheduling techniques to establish an integral management system taking in to account the un-certainties in the research environment. Based upon the results of a case study for the Liquid Metal Reactor Design Technology Development Project which is led by the KAERI this study also con-firms that it is possible to run the national nuclear R&D projects with the Scheduling & Planning.

The purpose of this study is to construct a new model named Communication Consensus Value Weighted (CCVW) model based on inter-personal technical communication within a project team, and to design Feasibility Estimates Integrated Terminal System (FEITS) which is a subsystem of R & D Project Planning System/System Alternatives Feasibility Estimation System (RDPPL/SAFES) using the model as a key function for feasibility estimation in that system. This new model aims to integrate technical feasibility estimated by several estimators in the lowest level as the project work breakdown structure which is the indentical conception of a terminal system in RDPPL. The process to obtain the feasibility estimate integrated is presented in this paper.

This paper presents a six sigma project for improving gate painting quality in a medium-sized automotive part company. The project follows a disciplined process of five macro phases: Define, Measure, Analyze, Improve, and Control. A CTQ(critical to quality) is determined based on COPQ(cost of poor quality) analysis, and a process map is utilized for identifying process input variables. Three KPIV s(key process input variable) are selected; Painting Temperature, Painting Quantity, and Painting Viscosity, and DOE(design of experiments) is utilized for finding the optimal process conditions for three KPIVs. MINITAB software is used for data analyses and DOE. The sigma level of defects rate has improved from 2.93 to 3.66.

A variety of Urban Rail Transit (URT) systems have been operating and they have different technology bases, causing a lot of difficulties in taking measures against trouble, training, upgrading, interoperability and so on. As such, a standardization project has been carried out to solve the problems by setting up the national standards for URT systems. A common database was built to provide the integrated engineering environment to the community of URT project. This paper discusses the design of the database and how it can be utilized in the successful promotion of the project. The products of the projects are stored into the database with traceability management to be referred to by other new URT projects for reusing and sharing the acquired knowledge through cross organizations.

The purpose of this paper was to explore delay avoiding measures and strategies. The paper was based on previous work of authors on finding delay causes. Firstly, the paper has discussed about delay avoidance measures prescribed by the previous work. As the previous study identified five main causes of construction delays, various measures and strategies to overcome those delay problems have been discussed in sequence in the last sections. Major delay prevention strategies are: involving stakeholders in the project decisions, outreach program, realistic time and resource estimation, try to adjust the triple constraints of time, cost and scope, ensure fair and complete disclosure of information at an early stage of the construction project, contractor, itself should inquire about patent design errors prior to submitting its bid, owner should include in its contract with the consultant an indemnity (protection) clause etc.

기업은 비즈니스 프로세스 조정 또는 기업의 전략적 목적을 달성하기 위하여 정보 기술을 도입하고 있다. 또한 데이터 일관성에 대한 요구에 대해서는, 소프트웨어 개발에 적용되어 표준화 규율을 채택하여 이를 따르는 소프트웨어 개발 회사들이 늘어나고 있다. 이는 사용자들의 요구일 뿐만 아니라 이러한 규율을 채택함으로써 적은 비용으로 더 나은 결과물을 얻을 수 있기 때문이다. 프로젝트 관리 도구를 사용한 체계적이고 일관적인 소프트웨어의 개발은 더욱 더 중요한 의미를 가지게 된다. 따라서, 본 논문은 효율적인 데이터 사전관리를 통하여 효과적으로 시스템 구축 지원을 할 수 있는 프로젝트 관리 기법에 대하여 기술한다.

This study investigated the needs and effectiveness of the application of Computer-Aided Systems Engineering Tool in order to enhance the chance of success of the large and complex system development projects like City Train System. Furthermore, it was shown that the merits of Systems Engineering and Project Management must be complementary to each other in their interaction in a project. Especially, for the project plans must be executed based on the fully understood system being developed, the technical and management data of the system development need be integrated and be able to support exact and rapid decision making of project planning. As an alternative solution approach, a model for development knowledge capture integrating both technical and management data of system development was proposed using Computer Aided Systems Engineering tool-Cradle.
