  • The change in environment of construction industry and the advancement of information technology require the improvement of construction project efficiency. However, construction industry still lacks performance-measuring tools that are the requirements of efficient project management system. In case of the schedule management system, schedule is usually being managed by result-oriented measurements such as completion time, spent cost, and progress rate, which are not good enough to control the overall continuity of work-flow. This research aimed to systemize the overall construction process and to develop the indicators for measuring performance of TACT activities during finishing work period that can contribute to the systemization of TACT management.

  • 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.

  • CS(Customer Satisfaction) has been focused as one of the most important factors in business administration nowadays. After measuring and evaluating CS level, most companies are performing many activities to improve it. Therefore, it is very important for driving CS management to measure the exact CS level. When measuring CS level, however, CSI(Customer Satisfaction Index) is changed by the computing method of importance for CS factors, and the corporate strategy is changed by CSI. In this research, some computing methods are reviewed and compared through the analysis of real data. Also, a hybrid computing method for CSI is proposed and compared it with other methods.

  • 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.

  • 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.
