Although project management for new product development is a very important issue, only a few approach from project scheduling has been made. The traditional project scheduling research has focused on the project network with certainty, but the new product development project has some uncertainties in network; Some activities may not need to be peformed, and/or some precedent relationships between activities may not need to be kept. In this paper, a simulation model is introduced in order to reflect uncertainties in project network for new product development. This simulation model can be used as a project scheduling technique for product development. By repeating the simulation, the degree of the risk and the feasibility of the project can be assessed.

Reviewing the capacity and timing of Southwest sea offshore wind farms, additional farms developing, and potential farms, we devised the long-term plan of domestic offshore wind farms development. In order to rank many wind farms, we determined evaluation indicators and weights of priority. We applied economic and preliminary factors such as wind grade, depth of water, distance from substations, farms scale, MOU signed, and feasibility studies. After deciding the ranking of wind farms by the scores, we planed domestic long-term scenarios of offshore wind farms development to meet national energy policy objectives.

In the promotion of Chinese language, the funding that Confucius Institutes can rely on only comes from Hanban. From 2009 to 2014, the number of new Confucius Institutes opened is much higher than before. With the increasing number of Confucius Institutes established in various countries, the funding for promoting Chinese language has limited its development. The development situation of Confucius Institutes in Australia is diversified with very rich experience. The market-oriented development of Confucius Institutes has also tried many times. The Confucius Institutes in the Lancang-Mekong region have less experience but they can learn from various experiences from Australia to provide better ideas and paths for the development of Confucius Institutes in this region and the promotion of Chinese. This paper uses the strength, weakness, opportunity, and threat (SWOT) model to analyze the market feasibility of financial support for the development of Confucius Institutes and makes certain suggestions for the promotion of Chinese language in the Lancang-Mekong region.

The road network system of major domestic urban areas such as city of Seoul was rapidly developed and regionally expanded. In addition, many kinds of life-lines such as electrical cables, telephone cables, water&sewerage lines, heat&cold conduits and gas lines were needed in order for urban residents to live comfortably. Therefore, most of the life-lines were individually buried in underground and individually managed. The utility tunnel is defined as the urban planning facilities for commonly installing life-lines in the National Land Planning Act. Expectation effectiveness of urban utility tunnels is reducing repeated excavation of roads, improvement of urban landscape; road pavement durability; driving performance and traffic flow. It can also be expected that ensuring disaster safety for earthquakes and sinkholes, smart-grind and electric vehicle supply, rapid response to changes in future living environment and etc. Therefore, necessity of urban utility tunnels has recently increased. However, all of the constructed utility tunnels are cut-and-cover tunnels domestically, which is included in development of new-town areas. Since urban areas can not accommodate all buried life-lines, it is necessary to study the feasibility assessment system for utility tunnel by urban patterns and capacity optimization for urban utility tunnels. In this study, we break away from the new-town utility tunnels and suggest a quantitative assessment model based on the evaluation index for urban areas. In addition, we also develop a program that can implement a quantitative evaluation system by subdividing the feasibility assessment system of urban patterns. Ultimately, this study can contribute to be activated the urban utility tunnel.

Industrial complexes in Korea have been vigorously established by economic development plan and development policy of industry in 1960s. Recently, Korean government has promoted Eco Industrial Park (EIP) project to recycle by-products and wastes in industrial park In this study, we analyzed the physical and chemical properties for the sludges discharged from A industrial complex. And we investigated the economic feasibility and environmental impact of sludge to energy facilities. The analysis results indicated that the petrochemical industry were 92% in sludge production, the highest treatment amount was landfill, followed by incineration and recycling and then ocean disposal. Wastewater sludge and process sludge samples are collected and analyzed to use as basic data on economic feasibility and environmental impact. Weighted average heating value of sludge samples was 3,891kcal/kg. Based on this data, installation and operation costs, operation returns of operating the drying facility are estimated, compared with cogeneration facility. And this study examines how the payback period of each simulation(total 8 case) with the important parameter changes. As a result, it was found that what needs the shortest payback period is 3years with connection of drying facility and cogeneration facility based on the government's financial subsidy system.

Article 31(1) of the Libraries Act(Act No. 18547), which was completely revised on December 7, 2021, stipulates that "the head of a local government or the superintendent of a city/provincial office of education must formulate a plan for the establishment and operation of a public library in advance and obtain the pre-evaluation of the feasibility of establishing a public library from the Minister of Culture, Sports and Tourism." Through the preliminary feasibility evaluation at the construction stage of the public library, it is possible to adjust distribution to improve the adequacy of scale and resolve regional imbalances and gaps. In addition, it is expected to increase service satisfaction and operational enhancement by inducing faithful securing of core infrastructure (librarians, collection, facilities, systems, etc.) in terms of balanced regional development and public library construction. The purpose of this study is to develop and present the basic direction and feasibility evaluation model for establishment of public libraries. The proposed evaluation model is expected to secure the legal basis and institutional legitimacy of the pre-evaluation system for public library establishment and to prevent waste of tax due to poor construction and operation of public libraries.

This research starts from the questioning of current housing development situation on hilly sites in Korea. It aims to investigate various design techniques of terraced housing as an alternative housing type on sloped sites. Several generic solutions are proposed, as for site slope and stacking method, combination of dwelling units, access pattern, and sectional variation of unit space. By the comparative analysis of design proposals with the typical two-row vertical-access type, the efficiency of the proposed techniques are verified in terms of development density, provision of community space, habitability of dwelling units.

Design and construction of freeform building technologies are being implemented to reduce time and cost due to the development of materials and equipments. However, production of freeform concrete segments takes much more time and manpower than typical due to disposable mold and various shape. Therefore, manufacturing technology of freeform concrete segments need to be developed for securing economic and constructive feasibility. The objective of this study is development of efficient casting technology for freeform concrete segments in a short time. This technology includes details about the fluidity of concrete and the sectional shape of freeform concrete segments. And problem of cost and time can be solved. Also, mold can be reusable and freeform concrete segments will be produced quickly and accurately. After this study, productivity study for validation will continue through prototype development and example application.
