  • 건설 프로젝트에서의 VE는 예산낭비와 비효율적 요인을 서전제거하는 유용한 도구로 활용되고 있다. 이에 따라 2006년부터 건설교통부에서는 "설계의경제성등검토"를 총공사비 100억원 이상으로 확대 시행하고 있다. 그러나 이러한 제도적 뒷받침이나 기술적인 노력에도 불구하고 국내 설계VE는 수행과정에서 문제점이 지적되고 있어 효과가 극대화되지 못하고 있다. 효과적인 설계VE팀 구성으로 설계VE의 성과를 극대화하기 위해서는 설계VE팀의 역량평가에 대한 체크리스트의 개발이 필요하다. 따라서 본 연구는 설계VE팀의 역량평가 체크리스트 개발을 위한 기초자료로써 역량 평가항목을 도출하고 가중치를 산정하고자 하였다. 이를 위하여 설계VE팀의 특성에 따른 역량인자를 도출하여 팀 지식, 팀워크스킬, 팀 태도로 구별하여 구성하였다. 도출된 역량인자의 중요도에 대해 1차 설문조사를 실시하여 신뢰도와 타당도를 검증하고, 그 결과로 도출된 제 1, 2, 3계층의 역량 평가항목에 대하여 계층 분석적 의사결정기법을 활용한 2차 설문조사를 실시하여 가중치를 산정하였다.

  • One of the prime objectives of school science is to help the children learn science concepts and conceptual schemes that will help them understand and interpret their environment. One of the basic scientific concepts is 'Change -everything existing in universe is changing always'. The purpose of this study was to investigate the characteristics of elementary and secondary students' conception of change. The subjects for this study were 489 students in Korea; 111 fourth graders, 95 sixth graders, 140 seventh graders and 143 ninth graders. Four items - mountain, river, ground, sea -were used for investigating students conception of change because representing the nature world in elementary and secondary level. The subjects were asked to check whether each item was changing and to explain each their check. Students' explanations were classified by whether they were sound understanding geologically, or not. The rate of responses that each item was changing was compared by grades and the rate of geological explanations was also compared by grades. Because students' conceptions of change might were effected by time scale, the additional questions that asked students whether the present status of four items were equivalent to the that of several points of time. As a result, the rate of scientific answers and patterns of explanations were similar by grade and the rate of geological understandings was relatively low. The frequencies of concept of change were more dropped as the point of time was closer to present.

  • In order to investigate how upper limb motion gives influence on clothing, this study measured tests by following standards: Front Vertical motion, Side-Vertical motion, and Horizontal motion. For this study, the procedures in the order of alphabet are applied. A. Eeach of testee's pattern was copied by the motion with a method of tight fitting technique. B. Analyzing each of the size-change on measuring item. C. Studying the moving aspects at each datum points. The results shows that the biggest change can be found in the following items. 1) In vertical motion of F4 (the length to shoulder point from A-point) 2) In horizontal motion of F5 (the length to front-width point from A-point), the check-result gained by checking the notice between motions shows that the most noticeable items are F4 (the length to shoulder point from A-point), F5 (the length to front-width point from A-point), F6 (the length to armpit point from A-point), B7 (the length to side-waist point from B-point). In result of the study of datum point's movement by motion, the items which were measured with the longest on straight-distance in vertical motion are the front and rear-shoulder, and the rear-shoulder, front-armpit in horizontal motion each. In the movement of each datum points by length, the check-result gained by checking the notice between motions shows that the most remarkable item is the front-shoulder.

  • This comparative study was conducted to compare the attitudes of sexuality and knowledge of sexual violence between male and female college students. The subjects of this study were 222 male students and 200 female students. The survey was conducted using a questionnaire of 3 general characteristics, 11 items to test attitudes on sexuality, 10 items to test knowledge of sexual violence, 1 item on the cause of sexual violence and 1 item to check knowledge of sexual violence countermeasures. According to the SPSS/PC Program, Frequency, mean, percentage, t - test, Pearson correlation coefficient were used in analyzing the data. The results of the study are summarized as follows. 1. The result of the comparison between two groups was significantly different in their attitude on sexuality(t= -4.16, P<.000). Female students had higher scores than male students. 2. The result of the comparison between two groups was significantly different for their knowledge on sexual violence(t= -6.82, P<.000). Female students had higher scores than male students. 3. As a countermeasure for prevention, sex educations is needed(27%). 4. Very high correlations were observed between a subject's sex and his /her sexuality(r=.1990, P<.0001), between a subject's sex and his /her knowledge of sexual violence(r=.3157, P<.0001), between a subject's attitude on sexuality and his /her knowledge of sexual violence(r=.2538, P<.0001).

  • Port State Control (PSC) is the inspection of foreign ships in national ports for the purpose of verifying that the condition of the ships and its equipments comply with the requirement of international conventions and the ship is manned and operated in compliance with applicable international laws. On the other hand, check items in PSC are nearly similar to periodical survey of Classification Societies, because they have the same background regarding safety and maritime pollution prevention. The purpose of this study is to develope computer-aided information system for ship inspection item which is useful for effective implementation of Port State Control. For this work, the status of PSC is reviewed, and the related scheme of ship survey system in Classification Societies is investigated. On these bases, a computer software integrated database system and object-oriented technique is developed. The developed system is expected helpful to establish and maintain an effective system of Port State Control.
