하둡 기반 Many-Task Computing 응용 실행 최적화 기술 연구
최진영,강대철,김직수 한국정보과학회 2019 정보과학회 컴퓨팅의 실제 논문지 Vol.25 No.12
MTC (Many-Task Computing) is a new computing paradigm that efficiently processes a significantly large number of tasks with relatively short running times. MTC paradigm can be applied in various scientific domains, and in order to effectively support these MTC applications we must devise high-performance task dispatching mechanism, dynamic resource allocation & load balancing scheme, and support for another type of data-intensive workload (compared to existing Big Data). We have developed MOHA(Mtc On HAdoop) framework which can effectively support MTC applications on top of the Hadoop platform. In this study, we propose an optimized environment for MTC application execution by verifying the high-performance task dispatching capability of MOHA, and conducting a comparative analysis of the HDFS and Lustre parallel file system. MTC(Many-Task Computing)는 상대적으로 짧은 작업 실행시간을 지니는 대규모 작업들을 고성능으로 처리하고자 하는 새로운 컴퓨팅 패러다임이다. 다양한 과학 응용 분야에서 MTC 패러다임을 요구하고 있으며, 이러한 MTC 응용들을 효과적으로 지원하기 위해서는 기존 배치 스케줄러의 성능을 뛰어넘는 고성능 작업 배포, 동적인 자원 할당 및 로드 밸런싱, 기존 빅데이터 응용과는 또 다른 형태의 데이터 집약형 워크로드 지원 등과 같은 기능들을 필요로 한다. 이에 따라 본 연구팀에서는 하둡(Hadoop) 플랫폼에서 대용량의 태스크들을 효과적으로 처리할 수 있는 MOHA(Mtc On HAdoop) 프레임워크를 개발하여 고성능 태스크 배포 성능을 확인하고, MTC 응용을 위한 스토리지 최적화를 위해 하둡의 기본 데이터 스토리지인 HDFS와 슈퍼컴퓨팅 분야의 Lustre 병렬파일시스템의 성능을 비교/분석함으로써 MTC 응용 실행에 적합한 환경을 제안하고자 한다.

본 연구에서는 공학교육인증과정을 운영하는 프로그램에서 소속 학생들의 성공적인 학습성과 습득을 보장하 기 위한 관찰 및 관리 수단으로서 학업성취도 관리시스템 구축의 필요성 및 운영 사례를 소개한다. 본 대학의 전자공 학 프로그램을 대상으로 관련 데이터베이스를 구축하고 학생들의 교과목 이수 이력 및 학습성과 성취도를 점검할 수 있도록 하여 학생들은 스스로 학업 계획을 수립할 수 있도록 하고 교수들에게는 학생별 맞춤식 상담이 가능하도록 하였다. 구축된 시스템에서는 학습성과와 관련된 각종 통계도 제공하도록 하여 프로그램 차원의 학습성과 관리가 가 능토록 하였다. 본 논문에서는 개발된 시스템의 성공적 구축 및 운영 예를 제시함으로써 공학인증과정의 운영에 필요 한 각종 통계지표의 계산 및 제시가 가능함을 보인다. In this study we explain the necessity of a developing management system of academical achievement in a progrm running the accredited engineering program as an observation and management tool to assure students' succesive achievement of program outcomes, and also present an operation result of the constructed management system. Taking the electronic engineering program in our school as an object, we constructed a relating database to monitor the students' course work completions and achievement of program outcomes, to allow students to build their plans for course work and to enable professors to proceed customized counseling for assigned students. The constructed system also provide various statistics relating program outcomes to allow program professors to proceed effective management of outcomes in the program level. In this paper we show that it is possible to calculate and provide the various statistical indicators, which is needed to effectively run accredited engineering programs, by presenting the results relating successful construction of the system and its operation.

동북아 자동차 산업의 현황 및 경제협력에 관한 연구 : 한.중.일 중심으로
최진영,신용하,김동기 경기대학교 부설 산업기술종합연구소 2002 산업기술종합연구소 논문집 Vol.24 No.-
Under the sudden change of competitive environment, the economic cooperation as a part of survival strategy is being a big issue among countries. There was much discussion based on the geological adjacency as well as cultural homogeneity regarding the economic cooperation of three countries, Korea, China, Japan. It has been also known that major trade countries of the world concluded the treaty of region trade, then extended the number of export, and drew a success in foreign direct investment. It can be considered that Korea will play a major role in the three countries' automobile industry based on Japanese demonstrated technology. Chinese resources, market and experience with their economic cooperation. Therefore it is expected that a big result will be achieved throughout such a role play of each country. This paper has a purpose to light up the distinctive quality and the present condition of each country in automobile industry, and to promote the foundation of three countries' economic cooperation. It is convinced that the economic cooperation of three countries. Korea, China and Japan in automobile industry, will play a great role in the world automobile market.

In this study, we analyzed the whole design of the necklace in detail, which reflects the artistic sense of handicraft in couture. The purpose of the study was to identify the characteristics of the design based on the analysis findings and to provide basic data to help fashion designers. The research method entailed analyzing trends in necklace design - viewed in fashion magazines and on websites - by year, season, brand, kind, material, color, and image. The identified necklace design characteristics were as follows. First, artistry and originality are dramatically expressed through the use of a broad range of materials. Second, due to the necklace’s role as an object of perfect beauty, in a number of images, the necklaces were presented in convergence and contrast with overall costumes. Third, the dramatic effects of layering revealed a strong presence and individualized styling. Necklaces are created with diverse sculptures by realizing the creative imagination of fashion designers. Even though they looked a little different every year, there were designs in the collections constantly. Round shape and princess length were preferred. In particular, the mix type was used to express dramatic effect by focusing neck part in entire styling which different length of necklaces were layered and worn. As a result, it meets the needs of consumers who emphasize brand differentiation and diversity, and it is believed that the role of necessities in fashion will continue and it creates economic demand in the fashion industry.
