The study intends to find out contents and impacts of rural development projects implemented by government in Ucheon myon-center village (Hoingseong-county) between 1989-1995. The projects in concern are Rural Industrial Estate Project(1989-90) and Rural Collective Village Project(1992-93), The restructuring of village plan introduced new construction and renewal of buildings that are required for a myon-center in general has to be. The study reveals some morphological patterns the village has and needs to be adjusted. As a conclusion, it proposes a conception of self-containment for a myon-center development. It is necessary that a project plan strategy should be based upon harmonious exploitation between old and new, flexible planning, and sense of technological alternatives.

In many project-oriented production systems, e.g., shipyards or large-scale steel products manufacturing, resource loading by an activity is flexible, and the activity duration is a function of resource allocation. For example, if one doubles the size of the crew assigned to perform an activity, it may be feasible to complete the activity in half the duration. Such flexibility has been modeled by Weglarz [131 and by Leachman, Dincerler, and Kim [7] in extended formulations of the resource-constrained project scheduling problem. This paper presents a new algorithmic approach to the problem that combines the ideas proposed by the aforementioned authors. The method we propose involves a two-step approach: (1) solve the resource-constrained scheduling problem using a heuristic, and (2) using this schedule as an initial feasible solution, find improved resource allocations by solving a linear programming model. We provide computational results indicating the superiority of this approach to previous methodology for the resource-constrained scheduling problem. Extensions to the model to admit overlap relationships of the activities also are presented.

Various risk factors affect construction projects. Due to the uncertainties created by risk factors, actual activity durations frequently deviate from the estimated durations in either favorable or adverse direction. For this reason, evaluation of schedule uncertainty is required to make decisions accurately when managing construction projects. In this regard, this paper presents a new computer simulation model - the Repetitive Schedule Risk Analysis Model (RSRAM) - to evaluate unit-based repetitive building project schedules under uncertainty when activity durations and risk factors are correlated. The proposed model utilizes Monte Carlo Simulation and a Critical Path Method based repetitive scheduling procedure. This new procedure concurrently provides the utilization of resources without interruption and the maintenance of network logic through successive units. Furthermore, it enables assigning variable production rates to the activities from one unit to another and any kind of relationship type with or without lag time. Details of the model are described and an example application is presented. The findings show that the model produces realistic results regarding the extent of uncertainty inherent in the schedule.

This study is about a feasibility study for the practical using Urban Transit Maglev system based on systems engineering. First of all we defined what phase is matched with the project for feasibility study in the system life cycle and identified tasks that shall be done in the phase. Finally we suggested how to do in this project. The Urban Transit Maglev system is not wholly new system. It has similar architecture to a legacy urban railway system. But it is the system that is partially introduced new technology, because there are many projects have this characteristic within the country, we expect that this study may provide references.

Since 1996, the G7 R&D and High-Speed Rail development project have been accomplished and it will be completed in 2007. During that time, we have achieved the origin design technique based on technique development experience. However, in order to magnify and to promote the growth of the origin design technique for railway industry to be a growth motive industry in future from intensive speed elevation and new technique competition of advanced nations, we need to prepare the next generation high-speed rail technique and to sustain expansion of the technique with getting hold of new technique tendency of the world. Therefore, this paper make research into necessity of the next generation high-speed rail development project, making an analysis of foreign countries cases and forward plan.

Service-learning is a form of experiential education in which students participate in organized activities and develop a sense of civic responsibility while acquiring content knowledge of the discipline. The purpose of this study was first, to examine the underlying theories and principles of service-learning, and second, to present a case of systemic implementation of problem-based service-learning into a Product Innovation and Management class in higher education. The New Product Development for an E-Commerce Small Business project was developed for a community partner, BevShots, reflecting the needs of the firm, and was tightly woven into the course content. Students' participation in the project had a significant effect on increasing their awareness of the needs in the community and identifying their roles as citizens as well as enhancing their content knowledge learning. The community partner also received benefits for his business by participating in the project. Through this study, we aim to inspire fashion design and merchandising educators to implement service-learning projects/classes in the curriculum.

Technosignature, previously known as SETI(search for extraterrestrial intelligence), is the scientific evidence of past or present extraterrestrial civilizations. Since NRAO's Project Ozma was performed in 1960, most of the noticeable technosignature searches have been done by radio telescopes, hoping to find strong and narrow bandwidth signals that cannot be explained by known natural processes. Recently, the Breakthrough Listen project has opened a new opportunity for technosignature by utilizing both optical telescopes, radio telescopes, and next-generation radio telescope arrays. In this review, mainly based on NASA Technosignatures Workshop (2018), we review the current trends of technosignature surveys, as well as other possible methods for detecting technosignature. Also, we suggest what the Korean community could contribute the technosignature research, including the new SETI project with Korea VLBI Network (KVN).

As eco-friendly and sustainable architecture is becoming more popular, the interest in Korean traditional wooden buildings (Hanok) has also been increasing. The building technologies of the wooden construction have been actively developed in all over the world through the diversification of new materials and construction methods. On the other hand, the growth rate of wooden construction market is still slow in Korea. In an attempt to promote the Korean traditional wooden buildings, a comprehensive research project has been conducted. This R&D project is developing standard designs, new materials, and methods for modernized Hanok including houses, public buildings, long-span structures, and even high-rise buildings. To this end, the purpose of this study is to formulate a technological strategy for popularization of modernized Hanok. Influencing variables and issues are analyzed and defined first. At the same time, the five keywords have examined in the perspective of dissemination of modernized Hanok technology. Finally, a technology road map for strategic development of modernized Hanok is proposed through casual diagrams.
