  • We investigated on the submission of multiple candidates in speaker-independent speech recognition by VQ/HMM. Submission of fixed number of multiple candidates has first been examined. As the number of candidates increases by two, three, and four, the recognition error rates were found to decrease by 41%, 58%, and 65%, respectively compared to that of a single candidate. We tried another approach that the candidates within a range of Viterbi scores are submitted. The number of candidates showed geometric increase as the admitted range becomes large. For a practical application, a combination of the above two methods was also studied. We chose the candidates within some range of Viterbi scores and limited the maximum number of candidates submitted to five. Experimental results showed that recognition error rates of less than 10% could be achieved with average number of candidates of 3.2 by this method.

  • This study attempted to determine the characteristic features of postpartum dairy cows during their return to estrus. Moreover, it investigated the effects of abnormal ovarian cycles (AOC) on subsequent reproductive performance and the relationship between normal ovarian cycles (NOC) and the blood urea nitrogen (BUN) level postpartum. Incidentally, 56.3% of the Holstein cows and 66.7% of the Jersey cows had NOC, whereas the 43.7% and 33.3% of the Holstein and Jersey, respectively, had AOC. Within 100 days of calving, the cows with AOC had significantly lower rates of artificial insemination (AI) submission as well as pregnancy and a significantly longer interval to first AI, as compared to that in the cows with NOC. Additionally, the cows with NOC had a significantly higher first AI conception rate than that in the cows with AOC. In this study, of the 32 Holstein cows, 8 resumed their ovarian cycle within 20 days of calving, 10 resumed the cycle with 21-40 days of calving, 8 within 41-60 days of calving, while the remaining 6 did not resume their ovarian cycles until 60 days postpartum. Furthermore, the likelihood ratios of incidence of NOC are 0.93, 1.94, and 0.38, respectively, in the groups with BUN levels < 15, 15-19.9, and ≥ 20 mg/dl. In conclusion, AOC postpartum adversely affects reproductive performance such as AI submission rate, pregnancy rate, interval to first AI and first AI conception rate; moreover, an increase or decrease in the BUN levels beyond 15-19.9 mg/dL leads to the AOC postpartum.

  • We observed the symptoms that occur to students who dislike mathematics when they study mathematics and the data that mathematics is related to foreign language. This study investigated the relation between mathematics and foreign language. Continuous immersion aids not only in acquiring language but also in learning mathematics. For continuous immersion, it is essential to organize small class. We organized small class and compared large class with small class about how the relation between mathematics and language appears in achievement, rate of presence, rate of submission of report, and attitude and enthusiasm. Based on the result, we try to find out the way to increase understanding mathematics and level up the achievements.

  • We present an innovative method of multi-physics application involving energetic materials. Energetic materials are related to reacting flows in extreme environments such as fires and explosions. They typically involve high pressure, hish temperature, strong non-linear shock waves, and high strain rate deformation of metals. We use an Eulerian methodology to address these problems. Our approach is naturally free from large deformation of materials that makes it suitable for high strain-rate multi-material interaction problems. Furthermore we eliminate the possible interface smearing by using the level sets. We have devised a new level set based tracking framework that can elegantly handle large gradients typically found in reacting gases and metals. We show several work-in-progress applications of our algorithm including the Taylor impact test, explosive venting and additional confined explosion problems of modem interest.

  • 기업간 전자거래가 활성화됨에 따라서 표준 전자문서의 이용이 급속히 증가되고 있으며, 기업간에 교환되는 표준 전자문서의 종류와 형태도 변하고 있다. 초창기에 주로 사용되던 EDI 전자문서를 대신하여, 최근에는 XML전자문서가 활발히 사용되고 있다. 이를 위해 제정된 XML전자문서 프레임워크표준들은 대부분 기본적인 구문 규칙과 메시징, 그리고 표준문서에 대해서만 규정하고 있어서, 새로운 표준 전자문서 개발에서 효율성과 효과성을 확보하기가 어려웠다. 국제적 EDI 표준인 UN/EDIFACT 개발 경험을 반영하여, UN/CEFACT에서는 전자문서를 구성하는 데이터 항목을 컴포넌트로 만들어 전자문서를 개발할 때 재활용할 수 있는 방법론과 라이브러리를 제공하고 있다. 그러나 이러한 방법론과 라이브러리를 적용하여 전자문서를 개발하고 활용하기 위해서는 추가적인 많은 노력이 요구된다. 이를 개선하기 위하여, 이 논문에서는 UN/CEFACT의 표준 전자문서 제출 양식을 중심으로 등록저장소의 각종 자원을 재활용할 수 있고, 다양한 양식간의 자동화된 변환을 지원하는 시스템을 제안한다.

  • Purpose: This study compares and analyzes the design drawing changes that occur during the design process between hospital design competition and the final detailed design. Based on this, factors that can reduce the rate of changes in drawings are derived. The purpose is to provide basic data to lessen the rate of the changes in the process of architecture design and can be reflected in the design competition guidelines. Methods: In this study, cases of hospitals are selected which are built in 5 recent years. Then compare and analyze the drawings which was drawn in the process from submission of competition to final design. After investigating the design changes that occur after the design competition, analyze the fixed-elements which are the main causes of design changes. Fixed-elements can be narrow down into few architecture-factors such as vertical-core, shafts, public-corridor, HAVC, and mechanical/electrical spaces. Results: Result of the rate of changes in each selected hospital floors can be sorted into variable-elements and fixed-elements which tells that the higher the rate of changes of the fixed-elements, the higher the rate of changes of the variable-elements. Implications: In other words, it can be said as the lower the change rates of the fixed-element, lower changes in whole design changes which represents that the greater the efficiency can be shown in the design process.

  • With the increasing use of chemicals in domestic businesses, the possibility of fire explosion and poisonous material leakage accidents is also increasing. Accordingly, the Korea Occupational Safety and Health Agency(KOSHA) has implemented the process safety management (PSM) system for a long time. However, process safety report submission has been providing and operating e-PSM since 2016 to address these problems as it is difficult to increase budget spending due to the need for professional capabilities and commissioning the report to consulting institutions. Therefore, this study conducts questionnaires on whether e-PSM system that is well utilized in the field, focusing on existing PSM business sites. In order to find out the activation method that can solve the deficiency factors by analyzing various inconveniences and problems accurately, we propose three improvement methods as educational aspect, promotional direction of e-PSM system, and institutional aspect.

  • 배치 작업 스케줄러는 클러스터 환경에서 구성된 계산 자원을 인지하고 순서에 맞게 효율적으로 작업을 배치하는 역할을 수행한다. 클러스터내의 한정된 가용자원을 효율적으로 사용하기 위해서는 사용자 작업의 특성을 분석하여 반영하여야 하는데 이를 위해서는 다양한 스케줄링 알고리즘을 파악하고 해당 시스템 환경에 맞게 적용하는 것이 중요하다. 대부분의 스케줄러 소프트웨어는 전체 관리 대상의 자원 명세와 시스템의 상태뿐만 아니라 작업 제출부터 종료까지 다양한 사용자의 작업 수행 환경을 반영하게 된다. 또한 작업 수행과 관련한 다양한 정보 가령, 작업 스크립트, 환경변수, 라이브러리, 작업의 대기, 시작, 종료 시간 등을 저장하게 된다. 본 연구에서는 배치 스케줄러를 통한 작업 수행과 관련된 정보를 통해 사용자의 작업 성공률, 수행시간, 자원 규모 등의 스케줄러의 수행 로그를 분석하여 문제점을 파악하였다. 향후 이 연구를 바탕으로 자원의 활용률을 높임으로써 시스템을 최적화할 수 있다.
