This research analyzed the cases of math competencies-oriented assessment, integrating assessment and instruction, which had been conducted in an elementary school whose assessment system involves frequent tests from a formative perspective on assessment. The research outcome is as follows: First, the competencies-oriented assessment of integrating instruction made possible for curriculum restructuring and competencies-oriented teaching, whereas more emphasis needs to be focused on the assessment feedback. Second, assessment on math competencies involves multiple dimensions; therefore, it needs to be managed to prevent problems arising due to overlap between different competencies. Third, though it has been identified that with evaluation it is possible to recognize and gradually improve the areas short of competency, more practical studies need to be conducted in this regard. Fourth, even with the fact that various types of evaluation ensure its fairness, make an accurate interpretation of the evaluation result before arriving at a comprehensive assessment.

Under the goal of investigating the difference of staff perceptions in performance evaluations at local self-sufficiency centers, this study set out to examine whether differences would be found between team leaders or those in higher positions and the common staff in criteria, procedures, implementation, rewards, and feedback of performance evaluations. For that purpose, the investigator conducted a survey by mail with staff working for local self-sufficiency centers in 15 cities and provinces across the nation from September 6 to 30, 2010. Of 672 questionnaires that were distributed, 439 were returned. Of these, a total of 432 were used in latent mean analysis. The major findings are as follows: first, the staff at local self-sufficiency centers had a relatively negative perception of performance evaluation in terms of rewards for evaluation results. Secondly, the team leaders or those in higher positions had a more negative perception of performance evaluation in terms of evaluation criteria and rewards for evaluation results than common staff. Based on those findings, the study offered some implications with regard to performance evaluation systems at local self-sufficiency centers.

In this study, we prepared Eriobotrya japonica leaf extracts by several extraction processes and then evaluated their biological activities for their potential application as a new raw material of functional cosmetic. Their whitening effects were measured by tyrosinase inhibitory activities, and anti-inflammatory effects were determined by inhibitory activities of nitric oxide (NO) production. Among the several extracts obtained from E. japonica leaf, supercritical fluid extract showed tyrosinase inhibitory activities at the concentration of 10%. Inhibitory activity on NO production effect related to anti-inflammatory efficacy was in the order: supercritical fluid extract > ethanol extract > hot water extract. According to the results of MTT assay, cell cytotoxicity was not observed at all concentrations except for a 5% concentration of the 70% ethanol extract. For whitening effects, 30% ethanol and 70% ethanol extract showed mushroom tyrosinase inhibitory activity at the concentration of 5%. These results indicated that E. japonica leaf extracts could have the functional effects when they are added as ingredients in cosmetics.

This study examined the curriculum CQI forms implemented at A university for quality management and improvement of instruction. Under the reorganization of competency-based curriculum, University A has improved the CQI form so that the planning, process and outcomes of class can be managed systematically. This study proposes a CQI form through literature research and has undergone a revision process through external expert verification. The major findings are as follows. First, when developing the CQI form, the questions were composed to evaluate and reflux the entire course of the class, including the planning, operation, results, and feedback of the class. Second, it was divided into three stages such as last semester, current semester, and next semester to prepare a comprehensive analysis and improvement plan, so that the effect of continuous class improvement and reflux can be obtained. Third, integrating the lesson plans and lecture evaluation results in the preparation of CQI increased the convenience of instructors. Fourth, the objective results (achievement results for each evaluation tool, lecture evaluation results) were provided to the instructor so that they could sufficiently reflect on them. This study is significant in that it provides implications for future CQI development.

Background: Circulatory arrest under deep hypothermia is an important auxiliary means for surgical correction of total anomalous pulmonary venous connection (TAPVC), However, cardiac operations under deep hypothermic circulatory arrest are associated with the risk of post-arrest neurologic abnormalities. The purpose of this study is to evaluate the results of the surgical correction of total anomalous pulmonary venous connection without the total circulatory arrest. Materiai and Method: Between April 2000 and October 2004, hospital records of 10 patients were reviewed retrospectively. Result: The locations for abnormal anatomical connections were supracardiac in 7 cases, cardiac in 1 case, and infracardiac in 2 cases. The mean cardiopulmonary bypass time and aorta cross clamp time were 116.8$\pm$40.7 and 69.5$\pm$24.1 minutes. There was no surgical mortality. Postoperative complications were post-repair pulmonary venous stenosis in 1 case, pneumonia in 1, pneumothorax in 1, wound infection in 1,and diaphragmatic paralysis in 1. All patients without pulmonary venous stenosis were in NYHA class I at mean follow-up of 16.6 months (3$\∼$49 months) Conclusion: We could obtain excellent results by repair without the total circulatory arrest for total anomalous pulmonary venous connection.

To find out the most reasonable analysis conditions of paeoniflorin, different paeoniflorin extraction methods and various UV detector wavelengths were conducted with paeonia radix of 4-year old Euisung local variety. The most reasonable paeoniflorin extraction time by reflux apparatus was 1hr. and by ultrasonic apparatus was 3hrs. and those methods were completed only once. Concentration of paeoniflorin by reflux apparatuses at 1hr. and 2hrs. of extracting time were higher than those of ultrasonic apparatus, and the differences were highly significant. However, the differences of paeoniflorin concentration at 3hrs. and 4hrs. in two methods were not significant. In comparing paeoniflorin concentration of many lines, ultrasonic extracting apparatus was more simple and effective than the reflux apparatus. Paeoniflorin was more reasonable sensitivity at 240nm, and albiflorin was 254nm by HPLC. When paeoniflorin and albiflorin were analyzed simultaneously, 254nm was more stable than any other wavelength.

This research aims to find out the existence of considerable induced effect that the conventional I-O model cannot. First, we construct an environmental Social Accounting Matrix for Korea by combining statistics on the Korean GDP and I-O with physical data on the fossil energy consumption and $CO_2$ emissions. The impacts of productive activities on fossil energy consumption and $CO_2$ emissions are evaluated by calculating the e-SAM multipliers. By applying decomposition technique further, we get direct, indirect, and induced effects of production activities by industry. The result of decomposing the e-SAM shows that while the direct effect of the electricity industry is large, its indirect effect is very small. In the case of the primary metal industry, both the direct and the indirect influence of this industry were very large. On the contrary, in case of the service industry, the induced effect of fossil energy consumption was as high as 50% of the gross effect. These results suggest that different energy policies should be established for different industries. Also, the findings show the e-SAM model is better than I-O model in analyzing implications of policies on energy use in the economy.
