  • 건설산업의 환경변화와 정보기술의 발달에 따라 건설사업 효율성 향상의 필요성이 커지고 있다. 그러나 건설사업의 효율성 제고를 위한 관리시스템의 필수요건이 되는 성과측정 도구는 여전히 부족한 실정이다. 한편, 공정관리의 경우, 공사수행 결과로 나타나는 시간, 비용, 진도율 등의 실적위주로 관리되고 있으며, 진행단계에서의 전체 작업간의 연속적 흐름에 대한 관리는 제대로 이루어지지 못하고 있다. 따라서 본 연구에서는 건축공사의 계획단계에서부터 진행단계, 최종 평가에 이르는 프로세스의 시스템화를 시도하였고, 특히 택트 공정관리의 시스템화를 통하여 공사수행 과정 중의 마감공사 수행 정도를 측정할 수 있는 지표를 개발하고 이를 활용하는 방안을 제시하였다.

  • The purpose of this study was to provide analytic rubrics for measuring teamwork(PO6), communication and presentation skills(PO7), and life-long learning(PO8) based on theoretical concepts of performance assessment and rubrics. Also, this study analyzed data about performance assessment and rubics from courses offered through college of engineering. Participants were 34 senior engineering students who took the course 'Technical writing and presentation'. In the second week of the course, students were given the pre-test instrument which was developed for measuring students' understanding of program outcomes for this study. After performing project activities using rubrics, students were encouraged to complete the post-test instrument and the reaction questionnaire during the ninth week. The data were analyzed by using SPSS 14.0 and Microsoft Excel. The research findings are as follows. First, to promote and evaluate program learning outcomes appropriately, performance assessment-based on rubircs should be implemented. Second, in the reaction questionnaire about the rubircs, students answered that using rubircs for performing the project was very useful for understanding the performance procedures and assessment criteria. Third, the mean of understanding of program outcomes of students in post-test was significantly increased than in the pre-test(p<.0001). From the findings, performance assessment and rubrics should be used as evaluation tools at course levels in terms of promoting program learning outcomes for engineering education.

  • 최근 들어 고객만족(CS)은 기업경영의 가장 중요한 개념으로 인식되고 있고 대부분의 기업에서 이를 측정하고 평가하여 고객만족수준의 향상을 위한 개선활동을 수행하고 있다. 따라서 정확한 고객만족수준의 측정은 기업이 고객만족경영을 추진함에 있어서 가장 중요한 것 이 라 할 수 있다. 그러나 고객 만족수준을 측정할 때, 고객 만족 요소에 대한 중요도(가중치) 산출방법에 따라 고객 만족도(CSI)가 변하게 되어 경영전략도 크게 변하게 된다. 본 연구는 고객만족도 측정에 대한 여러 가지 가중치 산출방법에 대하여 살펴보고, 통계적 중요도 산출방법에 따른 각각의 결과를 실제 사례를 통해 비교 분석하여 장단점을 제시하고자 한다. 또한 각 방법의 장단점을 바탕으로 hybrid가중치 적용방법을 제안한다.

  • According to adaptive structuration theory, faithfulness of appropriation(FOA), and consensus on appropriation(COA) are variables for measuring appropriation in use of IT. FOA is the level of interpreting and using the intentions of the IT designers objectively and COA is the level of agreement on ways of using IT among or with user group independently of designers' intention. In traditional theories of IT adoption, computer self-efficacy(CSE), self evaluation on abilities of using computer, has been considered as one of the important individual differences. which would influence on beliefs of using IT. Therefore, considering the relationship among CSE, FOA, COA and attitude, we can hypothesize that CSE would play a moderation varaible among appropriation related variables relationships, FOA-attitude and COA-attitude. The objective of this study is an analysis of CSE's moderation effects in causality relationship among appropriation measuring variables. For this purpose, we propose a research model where there are four hypotheses for moderation effects of CSE on the relationships between appropriation variables. We test these hypotheses by sampling ERP and groupware users. In result, our proposed hypotheses except moderation effect of COA-usefulness are accepted. Main contribution of this study is to identify the relationship between CSE and AST. This study implies that very careful consideration of users' CSE is necessary in order to perform managerial activities based on FOA and COA in IT management department.

  • NGN 운용과정의 품질 보증을 위해 어떤 체계하에서 품질이 테스트 되어야 하는지 방법론을 도출하기 위해서 멀티미디어 트래픽을 중심으로 NGN 품질측정 프레임워크를 제시한다. 테스트베드는 NGN 운용과정에서 QoS 측정 메트릭스, 측정구간과 측정계위, 측정도구, 측정장비, 측정방법 및 측정결과 분석에 대한 일련의 프로세스와 방법론을 모델화한다. 이 모델은 향후 NGN 품질보증 활동에 활용토록 한다. 통신서비스 품질은 스스로 보장되지 않으며 끊임없이 측정되고 관리될 때에 만 품질 목표수준 확보가 가능하다. NGN 네트워크기술 패러다임 중요성을 감한할 때 NGN 운용상의 품질관리에 대한 연구는 앞으로 활발하게 추진되어야 할 핵심 소재이다.

  • Objectives : This study was undertaken to determine if a combined(SPe) has a protective effect against functional failure induced by $CCl_4$ in rat liver. Methods : Acute liver injury which initiated from free radical induced by $CCl_4$, were applied to rats and data were obtained. Liver injury was estimated by measuring aspartate aminotransferase(AST) and alanine aminotransferase(ALT) activity in serum. Lipid peroxidation was examined by measuring malondialdehyde, a product of lipid peroxidation. GSH activities in liver tissues were also measured. Results : When rats were treated intraperitoneally with $CCl_4$, serum AST and ALT were increased compared with the control, which was significantly inhibited by pretreatment of SPe. SPe also prevented reduction in GSH induced by $CCl_4$. Conclusion : Above results suggest that SPe exerts protective effect against $CCl_4$ by its antioxidant action in liver tissues. Thus, SPe may be used in prevention and treatment of drug-induced liver cell injury. However, the precise mechanisms of SPe protection remain to be determined.

  • Gloss uniformity on unprinted coated papers is oftenly called as 'Surface Feeling' in market and roles as a very important criteria when a customer choose a paper. However, there is few researches on this quality so far and even there isn't much knowledge on the characteristics of gloss variation, ie what it is, where it comes from etc. Therefore, there should be a pre-research on its characteristics, factors, measuring method or tools prior to the following development activities. In this paper, we obtained about a dozen of papers including foreign products and measured not only basic properties of them, but also various characteristics related to ununiformity. Our experiments went further to printing, but that area is excluded in this paper. Also, we investigated several instruments for measuring gloss variation by an objective way all over the world and tested with our own samples so that we tried to find out which one is best-correlated with visual appreciation and suggest its results as possible. We found out several things from these experiments including what is difference between good and bad gloss uniformity, the factors of gloss variation, and the results of measurement for gloss variation with instruments.

  • A shuttle vector for Escherichia coli and Giardia lamblia was modified to produce a reporter plasmid, which monitors the expression of prescribed gene in G. lamblia by measuring its luciferase activity. Promoter regions of the gap2 gene, one of the genes induced during encystation, were cloned into this plasmid, and the resultant constructs were then transfected into trophozoites of G. lamblia. Transgenic trophozoites containing one of the 3 gap2-luc reporters were induced to encystation, and characterized with respect to gap2 gene expression by measuring their luciferase activities. Giardia containing a gap2-luc fusion of 112-bp upstream region showed full induction of luciferase activity during encystation.

  • This study was carried out to investigate whether water extract of Sagunja-Tang and its composing herbs have the inhibitory effects on cytotoxicity and lipid peroxidation induced by oxidant in rat renal cortical slices. Cytotoxicity was estimated by measuring lactate dehydrogenase (LDH) activity and lipid peroxidation was examined by measuring malondialdehyde (MDA). a product of lipid peroxidation. When rat renal cortical slices were treated with tert-butylhydroperoxicle (t-BHP) of 1 mM and water decocted herbs. LDH release from the slices was inhibited in dose dependent manner at low concentrations of herbs. It shows that herbs can reduce cytotoxicity, but overdose of herbs can be toxic to the slices. And MDA measurements show each herb has its own activities of preventing cytotoxicity from oxidants. So further studies should be followed to make clear the mechanisms of anti-oxidative effects of herbs.
