Performance assessment was introduced to improve self-directed learning and method of assessment for differenced learning when the seventh educational curriculum was enforced. Written examinations often fail to properly assess students higher thinking abilities ad problem solving abilities. Performance assessment addresses this drawback and also allows normalization of class and school quality. However, performance assessment also has drawbacks that could lead to faulty assessment due to lack of fairness, reliability and validity of grading, ambiguity of grading standard etc. This study proposes a fuzzy performance assessment system to address the drawbacks of the conventional performance assessment. This paper presents in objective and reliable performance assesment method through fuzzy reasoning, design of fuzzy membership function. We define a fuzzy rule analyzing factor that influences in each sacred ground of performance assessment and accounts for the principle subject The proposed performance assessment method divides into three categories, namely, formation estimation subject estimation and design of membership function. Performance assessment result that is worked through fuzzy performance assessment system can reduce the burden of appraisal's fault and provide. We fair and reliable assessment results through grading that have correct standard mid consistency to students.

This study examined the influence of self-regulatory resource depletion and self-regulatory modes on fashion product purchase intention. Initial research design dealt with differences of the resource depletion effect according to self-regulatory modes. The study used a 2 (self-regulatory resource depletion: depletion/non-depletion) ${\times}$ 2 (regulatory mode: assessment mode/locomotion mode) between-subjects factorial design. Second, the research design empirically analyzed the influence of self-regulatory resource depletion and self-regulatory mode on the fashion product purchase intention by each product group divided by type and involvement of fashion product. The subjects for the initial research were 255 university students in Seoul, Gyeonggi, and Daejeon. The subjects for the second research were 873 university students in Seoul and Daejeon. Collected data were analyzed with SPSS statistical package with reliability analysis, t -test, analysis of variance (ANOVA), and analysis of covariance (ANCOVA). The results were as follows. First, assessment-oriented consumers showed low purchase intentions about fashion products when self-regulatory resources were exhausted than when self-regulatory resource were not exhausted. Locomotion-oriented consumers, indicated no differences in purchase intention about fashion products regardless of self-regulatory resource depletion. Second, influences on purchase intention by self-regulatory resource depletion and self-regulatory mode were different according to the fashion product group. The results of this study implied that strategies should be differentiated when establishing a fashion industry marketing strategy according to the self-regulatory resource depletion and self-regulatory mode of consumers.

Background: In monitoring exposure to environmental smoke (ETS), biomarkers can overcome the subjectivity and inaccuracy of self-reporting measurements, and have the advantage of reflecting ETS exposure in all places. This study aims to evaluate the effectiveness of ETS exposure measurement using biomarkers such as urine cotinine. Methods: This study used the Korea National Health and Nutrition Survey data from 2009 to 2018. A total of 28,574 non-smokers with urine cotinine data were selected for the study. The cotinine concentration and ETS exposure rate using urine cotinine was estimated and then compared with the self-reporting measurements. The degree of agreement among measurements of ETS exposure was confirmed. Results: As a result of measuring ETS exposure with urine cotinine, 23,594 (83.8%) out of 28,574 subjects were classified as to exposure groups. This estimate differs significantly from measurements made by self-reporting. In addition, the average concentration of cotinine in non-smokers has decreased to a 10th level over the past 10 years. Based on the biomarker, the sensitivity of the self-reporting was 8.5%-29.0%, the specificity was 16.4%-19.5%, and the kappa value was 2.0%-5.8%. Conclusion: The findings of our study show that self-reporting measurement does not well reflect the extent to which non-smoker's exposure to smoking materials. Whereas cotinine concentration has decreased significantly over the past 10 years, the ETS exposure rate has not reduced. It strongly suggests the need for intervention in the group of non-smokers exposed to low concentrations of smoke. Therefore, an assessment using biomarkers such as cotinine-based measurement should be made in the Health Plan 2030.

Purpose: The purpose of this study was to develop a self triage application for rescue requests by disaster vulnerable populations. Literature was reviewed in order to define application trends and needs. Methods: Development of the self triage application was conducted in six stages as a hybrid model (analysis, design, development, implementation, evaluation, modification) of the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model and Driscoll & Alexander model. Application system function and contents were tried with 6 experts and 4 people with hearing impairments. Results: Expert assessment of the application for self triage showed that reliability at 5 points was the highest, followed by utility at 4.8 points. Scores for quickness and expressiveness were low at 4.6 and 4.2 points respectively. User acceptability assessment of the application was measured at 66.73 points. Conclusion: The results show that the application for self triage is helpful to disaster vulnerable populations by providing relief in disaster situations. It is expected that use of this application as a self rescue ability can be made available for disaster situations. However, it will be necessary to establish policies for communication strategies with rescuers and public relations to improve the access rate of disaster app service.

The purpose of this study is to find out the effects of the diagnostic and formative assessment on elementary science classes. For this purpose, we developed the diagnostic and formative assessment test and provided them to students before giving them the equivalent and learning achievement tests. The results are described as follows: First, for the science class that took the diagnostic assessment; the test provided help in improving the students' learning achievement. Second, for the science class that took the formative assessment; the test did not provide help in improving the students' learning achievement and in improving their openness to learning opportunity only to self-directed learning attitudes. Third, for the science class that were given both the diagnostic and formative assessment test; the tests provided help in improving the students' learning achievement. It also helped in improving their openness to learning opportunity, initiative for learning, and passion for learning except in problem-solving skills on self-directed learning attitude. Therefore, I recommend the utilization of the diagnostic and formative assessment tests be provided to students in order to improve learning achievement and self-directed learning attitudes in science classes.

In this study, the effects of a self-assessment on the students' science concept understanding and science-related attitudes were investigated. Student's perceptions towards the self-assessment were also examined. Five classes from a middle school in Gyunggi Province were chosen. Two of those classes were assigned to the control group that no self-assesment tool was applied to and the other 3 classes were assigned to the experimental group which a self-assess-ment tool developed for this study was applied to. The experimental group was further divided into two groups for imple-ment of two kinds of programs. One experimental group was provided some feedback such as solutions to problems and the other was not provided any type of feedback. The tests of science-related attitudes were administered before and after the instruction period. The science concepts understanding test was done only after the instruction. The results of this study were as follows. There were significant differences between the experimental group and control group in under-standing of scientific concepts. The enhancement of science-related attitudes was also higher for the experimental group. Providing feedback to students was more effective in the improvement of students' science-related attitudes. However, there were no significant differences in understanding of scientific concepts in relation to the feedback in experiment groups. From the above results, it was acknowledged thet self-assessment applied to the middle school science class showed considerably positive influences on the improvements of the understanding of scientific concepts and science-related attitudes.
