  • In Korea, recent trends indicate an increase in the volume of the functional clothing market. This study investigated the evaluative criteria and information sources of functional clothing according to gender and age. A total of 756 responses were analyzed using descriptive statistics, MANOVA, and Duncan's test. The main effect of gender on the evaluative criteria and information sources of functional clothing was identified. Compared with male consumers, female consumers gave more importance to price and aesthetic criteria. Female consumers take advice from colleagues and companions, as well as use information obtained from mass media to a greater extent than male consumers. Age was seen to have an effect on evaluative criteria and information sources in purchasing functional clothing. Respondents in their forties and fifties took textile quality and durability more seriously. Information available on the Internet and following the dressing styles of celebrities were preferred by respondents in their twenties.

  • The purpose of this study was to investigate the effect of sports shoes benefit pursuit on purchase reason, purchase evaluative criteria, and purchase information resource of high school girls. The data were collected between June 2016 from 287 high school girls in their's, living in Seoul, Daejeon, Gwangju, Daegu, Busan, and Changwon. The data have been analyzed by using SPSS program. The methods of factor analysis, reliability, and regression have been adopted for the data analysis. The results of this study were as followings: The factors of sports shoes benefit pursuits consisted of four dimensions of fashion-pursuit, brand-pursuit, convenience-pursuit, and economy-pursuit. The factors of purchase reasons consisted of three dimensions of syntony, recreation, and economic utility. The factors of purchase evaluative criteria consisted of three dimensions of management, aesthetic appreciation, and symbolism. The factors of purchase information resource consisted of two dimensions of media and human. Sports shoes benefit pursuits had an influence on purchase reasons, purchase evaluative criteria, and purchase information resources. In particular, the fashion-pursuit of Sports shoes benefit pursuits had a great influence on purchase reasons. The brand-pursuit of Sports shoes benefit pursuits had a great influence on purchase evaluative criteria and purchase information resources. It is highly expected that this study is used as the useful sources of sports Shoes industry.

  • The optimal design of transmission system expansion planning is an important part of the overall planning task of electric power system under competitive electricity market environments. One of main keys of the successful grid expansion planning comes from optimal reliability level/criteria decision, which should be given for constraint in the optimal expansion problem. However, it's very difficult to decide logically the optimal reliability criteria of a transmission system as well as generation system expansion planning in a society. This paper approaches a methodology for deciding the optimal reliability criteria for an optimal transmission system expansion planning. A deterministic reliability criteria, BRR (Bus Reserve Rate) is used in this study. The optimal reliability criteria, BRR/sup */, is decided at minimum cost point of total cost curve which is the sum of the utility cost associated with construction cost and the customer outage cost associated with supply interruptions for load considering bus reserve rate at load buses in long term forecasting. The characteristics and effectiveness of this methodology are illustrated by the case study using IEEE-RTS.

  • This study analyzed content on education for sustainable development in middle school science curriculum of $6^{th}$, $7^{th}$, 2007-revised and 2009-revised. Analyses criteria were developed based on literature reviews. This study developed 8 criteria such as health, climate change, urbanization and rural development, water, biodiversity and ecosystem, energy, disaster reduction and management. The results showed that 6th middle school science curriculum has 4 criteria, $7^{th}$ has 2 criteria, 2007-revised has 8 criteria, and 2009-revised has 7 criteria. This study suggests the need for developing systemized teaching material on education for sustainable development that can be integrated in the science curriculum by pursuing the following tasks: First, the goal of education for sustainable development and its need should be stated in the science curriculum. Second, the class content, themes, objectives, teaching-learning programs on education for sustainable development should be produced. Third, within science curriculum, the content should deal with perspectives and topics, and learning goal must pursue value education.

  • Purpose: To provide Diagnostic Criteria and Severity Evaluation Criteria of postpartum edema mainly complained by women directly after delivery. Methods: We analyzed Edema Index(ECF/TBW) analyzed by Body Composition Analyzer(InBody720) of 103 women directly after delivery who were delivered in Ob & Gy of Dongguk University Ilsan Hospital. Results: Mean value for Edema Index of 103 participants was 0.3527$\pm$0.0102, Minimum was 0.336, Maximum 0.388. From this Mean value and Edema Index distribution of participants, We suggest that we can diagnose more than 0.35 of Edema Index as Postpartum Edema, more than 0.35 and less than 0.36 as postpartum edema grade 1, more than 0.36 and less than 0.37 as grade 2, more than 0.37 as grade 3. Conclusion: This research is the first step for diagnostic criteria of postpartum edema, we suggest that diagnostic criteria of postpartum edema is more than 0.35 of Edema Index score. But this suggestion must be revaluated by additional research.

  • In Modern society, various important systems is operated such as nuclear plant, chemistry industry, railway system and so on. But these systems can cause high risky accidents. Hence, these systems are required to ensure the individual and societal risk criteria. In this paper, we reviewed EU risk criteria which is already operated in UK and Netherlands, then we proposed acceptable risk criteria and estimated risk of oil immersed transformer for subway with FN curve.

  • Among common test methods of assessing structure safety for existing lightweight walls, the criteria of the quality assessment of the horizontal static load resistance has been considered ambiguous. In the current study, therefore, an experiment was conducted to figure out the standardized assessment criteria of the lightweight wall's horizontal static load resistance. Based on the findings of the experiment with gypsum board and ALC block walls, an acceptable amount of each standard and the variables of the stud wall arising from the appropriate load (1000N) on the wall in a daily life were accounted for, arbitrarily setting the maximum deformation amount below 15mm.
