Based on “Research to Create a Support System to Support Worker’s Career Development: Focusing on Office Workers”(Lee et al., 2007), The four areas of marketing, personnel, accounting, and production management were selected as those most requiring educational needs. With the aim of helping to develop Competency-based Curriculum(CBC) based on the four areas of Office Work, this research first derived competencies related to four areas of Office Work's duties through workshops and interviews then used these competencies to develop CBC, including measurement tools, road maps etc. the Procedures of CBC Development employed the following competency modeling after synthesizing the above research. a) In order to examine the results of a particular task, the results of various tasks were derived and grouped according to significant similarities. b) After examining and defining the competency necessary to achieve results, the knowledge, technology and attitude(K.S.A.) and behavior index was derived. c) After conducting interviews in order to determine the validity of the competency derived, the competency modeling was finally decided upon. After the competency modeling, the following methods considered most appropriate for educational process development were chosen (Kim e. al., 2005). Development of educational process after grouping the knowledge, technology, attitude (K.S.A.) into those with similar meanings Development of educational method after deciding on the priority of the competencies, creating the competency matrix, and formulating the program according to each unit Formulating a TA-centered program after determining the priority of the competencies and making a competency matrix. 이 연구의 목적은 중소기업 근로자 대상 교육과정 중 가장 니즈가 많은 것으로 나타난 마케팅, 인사, 회계, 생산관리 분야에 요구되는 역량을 도출하여 이를 기반으로 역량 기반 교육과정(Competency-Based Curriculum; CBC)을 개발하는데 있으며, 이를 통해 중소기업 근로자의 직무전문역량을 향상시킬 수 있도록 돕고자 한다. 본 연구는 역량을 기반으로 개발된 교육프로그램 뿐 아니라 직무별 역량진단 도구 및 TRM(Traning Road Map)을 제공함으로써 프로그램을 이용하기 위해 자신의 현재 상태를 주도적으로 진단하고 스스로 경력개발 경로를 구축할 수 있도록 하였으며 더불어 본 교육 프로그램의 성공적인 시행을 위한 운영방안에 대해 제언하였다. 이 연구를 진행하게 된 배경은 2007년 산업인력공단에서 중소기업 근로자의 핵심직무능력 향상훈련지원분야를 확대하고자 하는 국가의 요구에 맞추어 진행한, 이찬 외(2007)의 ⌜근로자 경력개발 지원체계 방안연구⌟ 연구에서 사무활동분야별 직무교육 필요성에 대해 조사한 결과, 마케팅, 인사관리, 회계, 생산관리 분야의 교육과정에 대한 니즈가 가장 높게 나타났으며, 제언으로써 4개 직무분야에 대한 직무역량도출 및 역량기반 교육과정개발에 필요성을 언급한 바 있어 본 연구에서 이를 수행하게 되었다. 본 연구의 특징은 중소기업 근로자들을 위해 기존에 제공되었던 교육과정과 차별화하여 근로자들이 자신의 직무를 수행하면서 요구되는 역량을 도출하여 이를 바탕으로 교육과정을 개발함으로써 실제로 업무수행에 필요한 역량을 향상시킬 수 있도록 시도했다는 점과 스스로 경력개발 경로를 구축해나 갈 수 있도록 자가진단도구와 학습경로 로드맵을 함께 제시하였다는 점을 들 수 있다.

다양한 NOx 저감 기법 적용에 따른 석탄가스화 복합발전사이클의 성능 변화에 대한 모사 연구
이찬 수원대학교 산업기술연구소 2000 산업기술연구소논문집 Vol.15 No.-
The present study investigates the performance variations of the IGCC(Integrated Gasification Combined Cycle) power block with various air integration desin concepts and NOx reduction schemes such as nitrogen dilution, saturation and fuel saturation. The present IGCC power block is assumed as a combined cycle which is composed of the Solar Taurus 70 gas turbine model and the bottoming cycle with single pressure HRSG(Heat Recovery Steam Generator). The syngas fuel into the gas turbine combustor is produced through the Shell gasification and gas clean-up processes of Datong coal. Nitrogen dilution is proven to be the most effective among three NOx reduction techniques, and results in both remarkable power output and efficiency improvements. In order to achieve additional NOx reduction, nitrogen saturation is more effictive than fuel saturation.

The cyclone, a key component of coal-based power plant, is designed and its performance and operation characteristics are verified by using CFD modeling and simulation techniques. In modeling the gas flow in cyclone, the present study employs discrete phase and Reynolds-stress turbulence models into Reynolds-stress averaged Navier-Stokes equation solver. Changing the size of fly ash particles, the gas velocity vectors, streamlines and particle tracks in cyclone are computed. From the flow prediction results, the collection efficiencies of cyclone are calculated and compared with the increase of particle size.

With the use of a CFD code, numerical modeling is made on the furnace and the cyclone of the CFBC plant using the RDF, solid fuel derived from waste plastic refuses of Korea. Based on 3-D and steady state generalized transport equation formulations of CFD code, the chemically reacting flow field in furnace is analyzed by modeling devolatilization and combustion processes of RDF and by combining standard κ-ε turbulence and P₁ radiation models.

A low noise axial flow fan is developed for cooling tower unit. In the present study, the basic fan blade angle distributions were determined with free vortex design concept to the design requirements. The camber line of each blade section was created as circular arc type and Clark-Y airfoil was mapped on this camber line. Then the center of gravity aligned stacking was applied to all the blade element sections along spanwise direction. The detailed flow filed and the performance map of designed fan were verified by using commercial CFD code and through-flow analysis method. The actual fan is manufactured with the use of FRP material, and then was tested in cooling tower unit. The measured performances and noise levels showed good agreements with predicted values.
