  • The work reported in this paper identifies the thermal-hydraulic phenomena that are expected to occur during a number of key transients in SMART(System-integrated Modular Advanced ReacTor) which is under development at KAERI. The result of this effort is based on the current design concept of SMART integral reactor. Although the design is still evolving, the preliminary phenomena Identification and Ranking Table(PIRT) has been developed based on the experts' knowledge and experience. The preliminary PIRT has been developed by consensus of KAERI expert panelists and AHP(Analytical Hierarchy Process). Preliminary PIRT developed in this paper is intended to be used to identify and integrate development areas of further experimental tests needed, thermal hydraulic models and correlations and code improvements for the safety analysis of the SMART.

  • The importance of efficient Supply Chain Management is increasing in accordance with recent industrial environment, such as globalization of business, complexity and diversity of company's management structure, and variety of customer's demand. In a rapidly changed environment of business, quick and efficient decision making is the important matter to the survival of the company. The purpose of this study supports decision making for efficient supply chain management. In this study, we consider simultaneously and mutually reflecting the preference of each constituent (Supplier, Manufacturing plant, Distribution center, Customer) on supply chain network, and decide company's strategic choice and coordinated production/distribution models of company. The Analytical Hierarchy Process is used for decision making of qualitative and quantitative elements. We use the results of AHP as inputs and propose mathematical models thru Mixed Integer Programming.

  • On the contrary to the expansion of feasibility studies on public construction and development projects, there is few feasibility studies on S&T, especially large-scale basic research facilities. Based on this critical mind, we tried the first feasibility study on large-scale basic research facilities, that is, the 4th Generation Light Source. First, it is validated whether the construction of 4th Generation Light Source is economically feasible and second, if economically feasible, the optimal place and time for construction are analyzed by using Analytical Hierarchy Process. This research shows that the construction is economically feasible irregardless of scenarios on future bio-medicine industry growth and to construct at Pohang in 2006 is optimal strategy. On the basis of this analysis, the feasibility studies on large-scale basic research facilities are expected to be more expanded and developed.

  • Korea has relied on top down development method, in which companies, research and education institutions move into the industrial complexes established by the government. However, to improve local competitiveness, the paradigm is shifting from the government initiated industrial complex to the clusters based on the cooperative network of the region. Representative case is 'Samcheok-si Fire & Emergency industry cluster construction project' that begun in 2007. AHP technique analysis results on first-stage showed that priority was on policy and network elements, and the results of second-stage analysis show that priority was on Policy incentives to internationalize the cluster and strengthen link,. Cluster branding, Sharing of organizational culture to cope with changes in environment, Creation of group learning culture. The subject of this research is limited to Samcheok-si's the Fire and Emergency Industry cluster formation project. Therefore, the research area and standard should be expanded to increase generality in further researches.

  • According to globalization of world economy on distribution and sales, logistics and transportation parts are play important role. Especially, it important to know and study how to choose right transport route and which is the key factor of route choice model in multimodal transport system. Thus this study aims to consider 4 main factors: cost, delivery time, freight, and logistics service factors additionally dividing into 13 sub factors and object is forwarders between Mongolia and Korean freight transport. The survey is based on AHP through interview with company officials. The paper provides empirical insights about current status of Mongolian forwarders and difference of the important factors between transportation modes. Result shows that time factor is role factor to choose transport route and then cost factors. Additionally, this study shows 2 different route choose factors between air transport and shipping transport forwarders.

  • 한국에서는 많은 산업재해로 인해 물질적 손실뿐만 아니라 국가 신뢰도에도 영향을 미치고 있어 선진국이 되기 위해서는 산업재해를 획기적으로 줄여야만 한다. 산업재해 예방을 위해서는 여러 방법 중 각 사업장의 안전관리를 담당하고 있는 산업안전관리자를 좀더 효율적으로 양성할 필요가 있다. 효율적인 안전관리자를 양성하기 위해서는 이들의 교육과목이 체계적으로 연구되어 각 과목들의 상대적 중요성의 분석이 필요하다. 본 논문에서는 이들 교과목의 상대적 중요도를 분석하였고 이의 타당성을 평가하였다. 안전관리자를 위한 상대적 중요도 분석은 AHP(Analytical Hierarchy Process)를 이용하였다. 분석결과 안전관리분야(W=0.355), 인간공학 및 시스템안전분야(W=0.242), 기계안전분야(W=0.13), 건설안전분야(W=0.12), 전기안전분야 (W=0.091), 화공안전분야(W=0.062)순으로 안전관리분야와 인간공학 및 시스템 안전분야의 상대적 중요성이 높게 평가되었다. 이러한 결과는 학교 교과목뿐만 아니라 산업안전공단이나 산업안전협회 등의 안전교육 계획수립 시에도 많은 도움이 될 것이다.

  • 온라인 미디어의 발전으로 인터넷 신문 웹사이트의 유형과 범위도 확대되고 그에 따른 정확한 평가가 필요해지고 있다. 특히 웹사이트의 유형에 따라 평가요인의 상대적 중요도가 다르기 때문에, 그에 따라 요소들의 중요도를 정확히 추출하는 것이 중요하다. 그러나 인터넷 신문 웹사이트 평가요소를 합리적으로 산출하는 방법에 관한 연구는 아직 미흡하다. 본 논문에서는 인터넷 신문 웹사이트의 특화된 요인을 산출하고 분석하기 위하여 HP 기법을 적용하였다. 특히, 인터넷 신문 평가를 위해 처음으로 평가 요소의 가중치를 활용하였다. 이러한 신출물에 대한 분석 결과는 새로운 인터넷 미디어 서비스 개발에 활용될 수 있다.
