  • Engineering is a value-adding process applying knowledge and skills in the construction industry that includes the planning, feasibility study, project management (PM), front end engineering and design (FEED), detail design, procurement, construction, supervision, and operation. Among these engineering activities, FEED is defined as a comprehensive design practice in the early design phase focused on conceptual design and basic design. It is a particularly influencing area that determines the competitiveness of procurement and construction capability of construction firms (KNIN 2013). Nevertheless, previous studies in FEED have been limited to the design process, deliverable, or particular management technique (e.g. system engineering, collaboration, information etc.). In this context, the purpose of this study is to propose a comprehensive FEED business process structure for project management of thermal power plant construction projects encompassing the entire project life cycle. And an assessment methodology for FEED functions was developed. It is expected that the proposed structure of FEED functions and FEED evaluation methodology will contribute to improvement of competitive capability of engineering, procurement, and construction (EPC) companies.

  • The purpose of this study is to explore changing attitudes towards old urban environments, represented in the comprehensive plans of Seoul, from the first 1966 plan through the most recent one of 2014. The results of analyzing all 6 Seoul urban comprehensive plans are as follows. The contents for considerations and actual planning actions for old urban environments were presented from the third comprehensive plan of 1990. The term 'historical heritage' was first applied in the urban park planning of the 1996 plan. In the 4th comprehensive plan of 1997, it began to regard historical landscapes as 'precious heritages' to make plans for using historical heritages in parts of landscape, education, and tourism. The scope of 'historical heritage' in the comprehensive plans has been expanded. This tendency continued to expand in the 5th plan of 2006, and again in the 6th plan of 2014. At the same time, in pursuing the identity of Seoul, 'historical heritage' in old urban environment came to be materialized further as planning objects.

  • Since 1993, Korea Institute of Design Promotion has carried out Design Promotion Comprehensive Plan every 4 years and due to the institutes founding purpose the plans are mainly focused on enhancing quality of merchandise goods. However due to social and economic changes now enhancing quality of cultural living through design is becoming important as ever. The purpose of this paper is to find our characteristics and changes in design policies and programs to diffuse design culture in the plans. The researchers have inquired proceeding studies on cultural and design policies and also looked into cases that were carried out in Europe to diffuse design culture. By analyzing EU's Cultural Policies four means were found: Education, Exchange, Participation, and Sharing. The results are as follows. First, in the beginning main focus was to educate people about the importance of design and what good design is, in bureaucratic ways. In the Secondary plan, reaching out to local regions begin to show in order to diffuse design culture that was and still is mainly centered around Seoul. Thirdly plan shows more exchanges but not only limited to domestic regions but international wide. In the Forth plan, participation programs and those engaging design to solve social problems are shown but still not much attention is payed to sharing.

  • The purpose of this paper is to propose an analytical model for evaluating Internet Web sites, that is comprehensive and flexible enough to accomodate different categories of Internet Web sites. This paper is intended to identify critical success factors of Internet Web sites to determine criteria for evaluating the Web sites, and use the criteria to develop a framework for comprehensive evaluation of Internet Web sites. The framework consists of eight categories, including design, business functions, trustworthiness, interface, technology, community, contents, and others. An empirical study designed to validated the framework has been conducted for each of the three Web site categories, including (1) information provision, (2) product sale, and (3) customer service. The results show that ‘content ’ is the most important for information provision Web sites, ‘trustworthiness’for product sale Web sites, and ‘design’ for customer service Web sites. The framework may be used not only as a tool to evaluate Internet Web sites, but also as a checklist to improve the quality of a Web site that is under development.

  • The U.S. Nuclear Regulatory Commission, Regulatory Guide 1.20 needs to perform a comprehensive vibration assessment program for reactor internals during preoperational and startup testing for nuclear power plants and extended power uprate. Although the measurement program is one of the core programs, it is rarely carried out except for a first-of-a-kind or a unique design. This article describes measurement results of vibration and stress for the comprehensive vibration assessment program for an APR-1400 reactor internals. The measurement was performed at an upper guide structure during the pre-core hot functional test of Shin Kori unit 4 reactor internals because the Shin Kori unit 3 and 4 are the first construction project for the APR-1400, and the upper guide structure assembly was to design change compared with the valid prototype. We confirmed that all measured results are within the test acceptance criteria. It means that the structural integrity of the APR-1400 reactor internals was secured for the flow-induced vibration.
