  • This study aimed to develop priorities alternatives based on relative rather than absolute assignments on clothing evaluative criteria. The relative comparison approach includes much redundancy and is thus less sensitive to judgemental errors common to techniques using absolute assignments. By deriving evaluative criteria for consumers in choosing clothing, and considering their relative important or value in the priority of evaluation elements. When the consumer selects clothing, it requires multi-criteria decision making exercise and needs to make trade-offs between different alternatives. With an application of the AHP's hierarchical structuring and pair-wise comparisons, this study will determine the weight and priorities of evaluation factor in clothing evaluative criteria in choosing cloth, which will eventually lead to improve management. Items for the setting priority were decided as 'symbol', 'practicality', 'economy', 'vogue', and 'aesthetic' by council. The data for this research were collected from respondents of 108 females in Busan. Data were analyzed by frequency and AHP. As the results, 'economy' was decided as a most important item. And 'a fashionable color' evaluated as that of first priority in the totality evaluation elements.

  • Multi-criteria ABC inventory classification is one of the most widely employed techniques for efficient inventory control, and it considers more than one criterion for categorizing inventory items into groups of different importance. Recently, Ramanathan (2006) proposed a weighted linear optimization (WLO) model for the problem of multi-criteria ABC inventory classification. The WLO model generates a set of criteria weights for each item and assigns a normalized score to each item for ABC analysis. Although the WLO model is considered to have many advantages, it has a limitation that many items can share the same optimal efficiency score. This limitation can hinder a precise classification of inventory items. To overcome this deficiency, we propose a context-dependent DEA based method for multi-criteria ABC inventory classification problems. In the proposed model, items are first stratified into several efficiency levels, and then the relative attractiveness of each item is measured with respect to less efficient ones. Based on this attractiveness measure, items can be further discriminated in terms of their importance. By a comparative study between the proposed model and the WLO model, we argue that the proposed model can provide a more reasonable and accurate classification of inventory items.

  • The purpose of this study was 1) to segment the middle-aged and elderly women's fashion market based on the clothing benefits sought by the buyer and 2) to compare the purchase criteria and fashion information sources among the segmented markets. The data were collected using a self-administered questionnaire in Seoul and its surrounding suburban areas. Factor analysis, ANOVA, Duncan test, and Dunnett's T3 tests were used to conduct the data analysis from 285 out of 300 questionnaires. The middle-aged and elderly women's fashion market was segmented into four groups; value-oriented, social status/trend-oriented, uniqueness-oriented, and protection/ convenience-oriented. All four groups were significantly different in terms of purchase criteria and fashion information sources. The social status/trend-oriented group used external purchase criteria, such as country of origin or brand and obtained fashion information from personal experience, advice from the salesperson, and celebrities. The protection/convenience-oriented group sourced fashion information from newspapers, the internet, and the radio. The uniqueness-oriented group put less importance on practical use/convenience criteria. Marketing strategies for these segmented markets were discussed.

  • The purpose of this study is to compare the preferences of the school mathematical terms of South Korea and those of North Korea by administering a survey for learners, inservice teachers, and pre-service teachers, to establish the criteria of desirable school mathematical terms, and to evaluate the school mathematical terms of South Korea and those of North Korea based on the criteria. According to the result of the survey, the preferred mathematical terms are different from one group to the other, yet the mathematical terms of South Korea are more preferred. In general, terms written in pure Korean and concise terms which are easily understandable are favored. To discuss about the criteria of desirable school mathematical terms, four perspectives were set up, 1) the semantic perspective and the regulatory perspective, 2) terms written in pure Korean and Chinese letters, 3) terms from everyday language and technical terms, and 4) the consistency. Six criteria were followed from the aforementioned four perspectives. Finally, various school mathematical terms of South and North Korea were reviewed in the angles of the four perspectives and the six criteria.

  • As firms increase their operations in the international arena, there is a growing need for managers to understand cross-cultural issues in adopting information systems(IS). The present study surveyed IS developers with respect to their perceptions on the importance of various criteria for successful development of information systems. The results indicated that developers perceive criteria related to the organizational and systems level to be more important than criteria on the strategic and user level. In addition, the developers perceive immediate/direct criteria as more important that indirect/long term criteria. The current study found little differences between developers working for innovative versus those working for non-innovative companies with respect to their views on the importance of various success criteria. There were also very little differences in the perceptions of IS developers at different hierarchical ranks.

  • This study examined the product evaluation criteria and post-purchase behaviors of secondhand fashion consumers. To achieve this, the study categorized secondhand fashion consumers by product evaluation criteria and investigated the differences in post-purchase behavior by consumer type. In-depth interviews were conducted with 18 participants for the qualitative research and an online survey with 500 samples was conducted for the quantitative research. The collected data were analyzed using factor analysis, cluster analysis, and one-way analysis of variance through SPSS Statistics 26. The results showed that the product evaluation criteria of secondhand fashion consumers were brand, scarcity, condition, design, and practicality, and their post-purchase behaviors were identified as reselling, giving away, and maintaining possession. According to the evaluation criteria, consumers were categorized into a high-interest group, a brand/scarcity-seeking group, a design/practicality-seeking group, and a low-interest group. As a result of analyzing post-purchase behaviors by group, the study found that each group displayed different behaviors.

  • The interference evaluation methods and criteria between the analogue TV/FM signals for BSS(Broadcasting Satellite Service) plans and the associated feeder link plans were established in WARC(World Administrative Radio Conference)-77 and 88. However, it should be applied the different interference evaluation methods and criteria of the digital TV signals from those of the analogue TV/FM signals. In this paper, the interference evaluation methods and criteria between the digital TV signals and the analogue TV/FM signals were analyzed. And also, the effects of the interference from the digital signals for Koreasat-1 into the analogue TV/FM signals for Japanese broadcasting satellite were evaluated. The amounts of EIRP reduction in the transmitting space stations were calculated to meet the interference criteria. The results showed that the digital BSS networks including Koreasat-1 would share the limited resources with the analogue BSS networks.

  • This study was conducted to compare protected areas of South and North Korea based on international conservation criteria and recommend new fundamental directions for nature conservation policy. International conservation criteria used by this research were the 1994 IUCN protected area categories, composed of 6 management categories. Despite a variety of types and names of protected areas created by different domestic legislations, South Korea was revealed to have only two types of protected areas, Category IV and V, indicating the significant lack of ecological diversity and representativeness in its protected area system. Shockingly, there are no national parks meeting IUCN criteria in South Korea. On the other hand, North Korea has three IUCN Categories of II, III, IV and thus more balanced and ecologically representative protected area network than South Korea. Especially, North Korea maintains 9 national parks to be officially recognized by IUCN and UN. However, both South and North Korea should make sincere effort to have new and well-designed protected area system including all IUCN Categories I -Ⅵ and particularly a minimum area in the stricter protected area categories.

  • The current load combination criteria for design of nuclear power plant structures are not based on the probability-based design concept but rely on the conventional design concept. In this paper, a load combination criteria for design of NPP coin-tainment structures are proposed based on a FEM-based random vibration analysis. More accurate reliability analyses under various dynamic loads such as earthquake loads were made possible by incorporating the FEM and random vibration theory, which is different from the conventional reliability analysis method. In this paper, the load factors for the design of NPP structures in Korea are proposed by considering appropriate fond combination criteria for design.
