  • In this study, the development of a three-screw pump for high-capacity discharge was carried out. Benchmarking and reverse engineering for advanced products were performed to design and manufacture power rotor and idler rotor for high capacity and high pressure. Through flow analysis, performance verification of the entire design was performed and prototypes were manufactured. As a result of performance evaluation on prototypes, it was found that the development specifications were satisfied.

  • This study was conducted to investigate the effect of absorption coefficient models on the P1 radiation model for a premixed hydrogen flame containing the water vapor. A CFD combustion simulation analysis was performed using XiFoam, one of the open-source CFD solvers in OpenFOAM. The solver using the flamelet combustion model has been modified to implement radiative heat transfer. The absorption coefficient models used in this study the grey-mean model and constant model, and for comparison, case without radiation was added. This CFD simulation study consisted of benchmarking the THAI HD-15 and HD-22 experiments. The difference between the two tests is the inclusion of water vapor in the condition before ignition. In the case of the HD-22 experiment containing water vapor in the initial condition, the simulation results show that the grey-mean absorption coefficient model has a strong influence on the temperature decrease of the flame and on the change in pressure inside the vessel.

  • Construction companies in Korea have shown interest in BIM (Building Information Modeling) even if late, adopted it, and applied it to several projects. But, it is hard to figure out the status of BIM implementation. Thus, this study is to figure out the status of BIM implementation in Korea by surveying major construction companies in Korea and comparing with similar surveys abroad. The survey result shows that only 11 companies in Korean construction industry adopted BIM. The clash check (73%) was mostly used among various BIM functions and other functions were used less than 30%. As of 2008, only 8 construction companies have used BIM in 27 projects and thus, Korean companies are in the BIM introduction period. Therefore, successful introduction of BIM is required by benchmarking the BIM introduction process of overseas construction industries

  • 본 연구는 부산항을 포함한 세계 주요 컨테이너 항만들의 효율성을 DEA(Data Envelopment Analysis)모형을 통해 상대적으로 분석함으로써, 부산항의 현재 위치와 더 효율석인 항만이 되기 위해 벤치마킹(Benchmarking)해야 할 대상을 구체화하였다. 또한, 본 연구에서는 일정시점의 효율성 분석이 아닌 1995년-2001년까지 7개년의 효율성을 시계열적으로 분석함으로써 각 항만의 효율성 변화할 살펴보았다. 분석 결과, 부산항은 95년, 96년을 제외한 나머지 연도에 대해서 비효율적인 항만으로 구분되었으며, 97년 이래로 효율성 지수가 다소 증가하고 있는 것으로 나타났다.

  • The purpose of this research is to find a better win-win growth strategy of Large and mid-sized IT service enterprises. Efficient win-win growth for large and mid-sized enterprises is essential for acquiring a solid global competitiveness in IT service industry. However, previous studies lack generalized and detailed findings, and therefore past strategies were based on fragmented analysis. To develop an efficient win-win growth for Large and mid-sized enterprises, global benchmarking and an in-depth analysis on deep-rooted problems in IT service industry has been conducted. Past and present policies on IT service industry have been reviewed based on desirable co-growth structure. Based on research, current policies are unable to support co-growth, and collaborative efforts between Large and mid-sized enterprises as well as square deals are necessary for win-win growth. A new policy paradigm has been derived and a roadmap for efficient co-growth strategy has been suggested. The results of this research can be used for building a better IT service industry polices. In future studies, a longitudinal analysis on the proposed co-growth strategy can be conducted.

  • This study aimed at setting up the grading indicator standards on development stages for phasing the continuous development process. To achieve the objective of this study, after referring to the proposed cases derived from the reference analysis, the development stages were classified. Also grading criteria of indicators according to development stages were established through the statistical analysis and expert group checking. Development stages of rural village were stepped into 4-stages through the reviews and analysis of reference literature ; preparation-entry-development-advanced stage. Reasonable achievement level of each development stage was established by considering the necessary development period and benchmarking reference target together. On the basis of these clear stepwise development phases, the grading criteria were proposed for determination of the incumbent development stages.

  • 최근 다른지역에 비해 상대적으로 정보화에 뒤진 ASEAN 국가들은 통신시장 자유화를 추진하면서 국가정보화실현에 심혈을 기울이고 있다. 역내의 IT협력을 위해 e-ASEAN계획을 추진하고, ASEAN+3 체제에서 IT협력을 도모하고 있다. 이런 상황은 우리나라가 IT강국으로서 ASEAN과의 IT협력을 강화하면서 전략적으로 ASEAN에 진출할 수 있는 기회를 제공하고 있다. 따라서 본 연구는 ASEAN국가의 IT정책과 IT인프라 현환을 심층적으로 분석하였고, 분석결과를 토대로 IT시장의 성장잠재성이 매우 큰 ASEAN국가에 성공적으로 진출할 수 있는 전략을 국가 차원과 기업 차원에서 제시하였다.

  • Purpose To meet changing social demands and fulfill the needs of the information and communications technology industry, the curriculum of MIS related department should develop and implement new conceptual frameworks. In response, the purpose of this study was to develop curriculum for students in the Department of e-Business at Kyungnam University. Design/methodology/approach We conducted a demands analysis of educational demanders, NCS(National Competency Standards) based curricular analysis, and benchmarking from other management information systems related departments. The expert panel committee consisting of e-Business department faculty members was held to examine and discuss the student-oriented curriculum developed during this study. Findings Results show that the contents and types of curriculum should be organized so that students can maximize their professional job competency to apply to their core professional tasks. Given these findings, we reconstructed the curriculum with both basic and advanced courses, all systematically organized according to the job requirements they offer toward meeting the industry's needs. We also implemented the web-based JSSS(Job Searching Support System) with which educational demanders can search among 13 job types, estimate their performances, and obtain the information about course registration. In all this study presents specific, practical evidence of the job-related curriculum for students in the Department of e-Business at Kyungnam University.

  • An efficient industry structure is essential for competitive IT Service industry in a global world. The purpose of this research is to derive a policy direction paradigm for strengthening IT service industry structure. To find an effective policy direction, an in-depth analysis on deep-rooted problems of IT service industry has been conducted. The root-causes of industry problems are found with new perspectives on IT service industry. Past and present policies on IT service industry have been reviewed based on desirable industry behavior. A new policy paradigm and a roadmap for efficient industry policy are suggested. To justify adequacy of new policy direction, global benchmarking has been performed. USA, Germany, and Japan's IT service industry has been reviewed based on global competitiveness and desirable eco-system. And an in-depth analysis has been performed for two big competitors, India and China, The adequacy of the new policy paradigm has been tested, and mostly approved. IT service industry policy needs to be transformed from manufacturing concepts to service concepts, from domestic focus to global focus, from zero-sum policy to positive-sum policy, from supplier focus to market focus, from internal industry itself to co-growth with main industries. etc. The results of this study can be used for policy adjusting and policy making to strengthen IT service industry's global competitiveness and to improve long-term performance of Korean economy. Further in-depth researches with quantitative analysis will be needed to fully justify the adequacy of the derived new policy directions.

  • 자료포락분석(data envelopment analysis)은 여러 종류의 투입요소와 산출요소를 이용하여 의사결정단위(decision making unit)들 간의 상대적 효율성을 평가하기 위해 많이 사용되는 기법이다. 본 연구에서는 자료포락분석을 이용하여 지방대학들의 연구 및 교육분야에 대한 효율성을 분석한다. 먼저, 우리나라 국 공립 대학들의 효율성에 대해 살펴보고, 지역거점대학(regional flagship national universities)과 비거점(non-flagship)대학 간의 효율성이 통계적으로 유의한지 여부를 탐색한다.
