The revised "Software Industry Promotion Law" has been effective from 2013. This law is to be basis of the domestic public information sector and increases the opportunities for small and medium-sized firms in participating the public IT projects. The shortcomings of this law may be the increase of the risk and the decrease of quality of projects. These suggest that the competencies of project manager (PM) s are critical. Also, in general, an SI (System Integration) project is a one that provides a customer with a customer-tailored system for system integration. Particularly, in an SI project involved in a public institution or a large corporation, the ripple effect of success or failure of a project is becoming greater as the system requires higher cost and more time due to high complexity and large scale. One of the solutions to address these problems is to investigate the competencies of a PM. Thus, in this paper, we derived the major competencies using the RGT (Repertory Grid Technique) and categorized the resultant constructs using the content analysis. In addition, we analyzed the level of importance of competencies by applying the AHP (Analytic Hierarchy Process). The conclusion was that Problem-solving Skill and Leadership were the most important competencies of a project manager.

Technology developments accelerate the change of the society and companies with unparalleled pace, so large scaled projects are in progress urgently. Large scaled projects deal with high technologies and massive tasks, and these need enormous labor force and costs, it is necessary to manage strategic conflicts based on human psychology and complex system theory. However, traditional management plan fails to suggest practical mechanism for successful projects. We study failure cases and key elements, leadership for projects, and suggest project management plan with psychological and behavioral economy approach by focusing on complexity and conflict structure on large scaled projects. Project behavior management plan, suggested in this study, is designed with phased strategy and practice to solve the failure of large scaled IT projects originally and preemptively. We verified the effectiveness of behavior management plan suggested by investigating experts and working groups, and stable projects are to be progressed with introducing this plan on large-scaled projects.

In order to promote the IT business efficiently, the Preliminary Feasibility Study has been conducted since 2004. It is to verify the feasibility of a large-scale IT project in advance and to determine whether to reflect the budget. It is more difficult to analyze the benefits of the IT project than other projects, because the IT project is carried out by combining tangible and intangible assets and human resources. For this reason, the Standard Guideline for Preliminary Feasibility Study in the IT field suggests a framework to support in estimating the benefits of the IT project. However, it includes the following problems : 1) level discrepancy among the benefit categories, 2) lack of types of benefit items, 3) no consideration of benefit inducing factors. So the framework is facing a low utilization. This study develops a new framework through a three-step research process. The new framework can be used not only for preliminary feasibility studies but also for estimating the benefits of general IT projects.

Urban-Hanok emerged as a result of urbanization of Hanok in the modern period. In particular, Urban-Hanok has been mass-produced from the early 1920s, when the population is concentrated in cities, until the middle. Large-scale development by the professional developer has been developed in large-scale land rather than individual client because housing shortage was serious problem. 11 Gahoe-dong was made in 1935-36 is representative Urban-hanok area of Bukchon. It was formed through division of large-scale Land in 1930's. In the 1930's, the large-scale development projects of Urban-Hanok was triggered by the two events. One is Land Investigation Project performed by the Japanese government to capitalization of property, another is the pro-japanese bought the large scale-land in Gahoe-dong at bargain price from The Japanese government. Each lot has still a topographical characteristics such as land-dividing quality, the way of development, characteristic quality of urban-tissue. 11 Gahoe-dong, Urban-hanok area was developed two ways. First, development have been adapted to the topography. The lots have reflected topographical conditions such as land cutting area, a retaining wall, land-diving was maintaining the original topography almost. Second, it was street oriented development. The lots have developed sequentially along the street. So, the lots's shape and size is different each. For this reason, this area distribute various type of Hanok.

In an early stage, many people think that agile development methodology cannot be applied i large-scale IT projects. Nevertheless, agile development methodology has recently been introduced in variety of successful large-scale IT projects. In this paper, I compare two enterprise agile methodologies and introduce a case of Disciplined Agile Delivery (DAD) Framework, an enterprise agile development methodology. I compare and quantitatively measure the productivity of the development of two projects using Disciplined Agile Delivery framework and waterfall development methodology with a similar development scope.

High speed railroad project management has been almost completed by starting operation of Seoul-Busan high speed railroad with the exception of a few constructing blocks currently in April, 2004. After Korea Rail Network Authority was established in 2004, it needs to develop new project management system for both conventional railroad construction and high speed railroad construction for domestic railroad projects, while it plans to invest in overseas railroad project for logistics innovation and improvement in passenger transport services on a large scale. Therefore this paper provides the method that we can adapt the project management system for high speed railroad containing experiences and know-how from construction of high speed railroad for both conventional railroad construction and high speed railroad construction or improve project management system for high speed railroad to use it as project management system for overseas railroad projects.

With reducing coal mining industry the number of coal mine sites between 1988 and 1998 was dropped from 347 to 12. Since the abandoned coal mine sites have been kept without any cares, they have raised various environmental and safety problems. Then, Korean government initiated a special law in 1995 for enhancing economic conditions and solving environmental problems with promoting developmental projects in the abandoned mining sites. As a result, casino business in Chungsun area has been opened to publics, and other large-scale developments such as ski slopes and resorts are planned. In addition, Boryung area in Chungchung province also will launch a large-scale project building golf courses. Based on this developmental trend, it is expected that lots of large-scale developments in other places will be taken place. In general, the large-scale developments have caused various environmental problems, and, thus, environmental aspects should be considered in a decision-making process. This paper examine the status of the abandoned mine sites in Korea and U.S. and suggests the alternatives of its utilization.

The information generated from large and complex construction projects transfer and evolve in long-term business cycle. Therefore, while there is any problem, such as delay, the cause of the problem might relate to the previous business process rather than where it arises. However, for complex project players and business relationships, it is unsuitable to search an information flow using traditional retrieval methods. This research addresses a relationship-based information search system to analyze the information flow in large-scale and complex construction projects. First, we identified the components of the information retrieval system customizing for a large-scale complex construction projects, and then developed the inference algorithm which define the relationship between business processes. For the validation, we applied the system on a business information system of urban regeneration projects and suggested some application using information flow retrieval system for project players and project managers. Using the system, players are easy to prepare for their work process and managers can define the causal flow of the problem.

A nuclear power plant construction project normally involves a large construction work of which the total project cost is over 5 trillion Won, Such a large-scale construction project has the risks of schedule delay and quality degradation due to increase in project cost, because designs are changed due to design errors. The reasons for design changes during installation are 1) insufficient engineering capability of the owner, 2) information discontinuance due to the multiple package method, and 3) inefficient constructability review processes. Accordingly, this study proposes, through problem analysis, a method of developing a constructability review system that utilizes constructability review processes and a data-based technology (3D modeling) that are optimized for nuclear power plant construction projects. It also presents a method of establishing a system for reviewing constructability in which constructability review processes and a Database (3D model, Schedule, Design change Items) are linked each other.

The 1960s is a transitional era in the history of architecture. The Byker housing redevelopment project well reflects this situation, and is a good example of materialization of social pluralism and expressional needs of a community. Therefore it was investigated in order to see its meanings in the history of mass housing in the Western countries. The conclusions are as follows: It is the first large-scale project where the concept of user participation was sucessfully realized; It suggested various tools of desirable design methodology; It made a paradigmatic change from modernism to post-modernism in the history of contemporary mass housing projects.
