The purpose of this study is to develop competitiveness evaluation index for global aviation training organizations. Research and studies on relevant documents were conducted to establish the index. With no sufficient study results previously done directly associated with global aviation training organization, relevant and related documents, such as studies on competitiveness evaluation index of higher educational institutions, were reviewed as an alternative. Two rounds of delphi surveys were conducted based on the review and consultation from experts in aviation training and human resource management fields. First round of survey with 62 evaluation indices were carried out, through which a total of 29 were selected, and 19 indices were chosen during the second round of survey. However, factor analysis was conducted in order to justify the survey result, which eliminated 3 more indices, with 16 finally selected. This study will provide implications for aviation training organizations which need to further improve their competitiveness globally.

본 연구는 H대학 전교생 필수인 IT 교과목 강의평가에 영향을 주는 요인에 대해 비교 분석하였다. 본 연구의 목적은 강의만족도가 학업성취도, 출석율, 수강과목군과 유의미한 상관관계를 가지는지 파악하는 것이다. 특별히 컴퓨터를 활용하는 실습이 많이 요구되는 IT 교양과목들의 강의 만족도가 일반 교양과목의 강의만족도 경향과 어떤 차이가 있는가를 확인하고자 하였다. 본 연구를 위해서 H 대학교에서 2019년도 1, 2학기에 진행한 교양 IT 교과교육과정의 12개 교과목에서 2,322명 수강생들이 제출한 2,149건 강의평가 결과를 자료로 사용하였다. 강의평가 결과는 객관식 선택형 문항의 평가점수 외에도 주관식 서술형 문항도 학생들이 제출한 서술문을 긍정형과 부정형으로 분류하여 계량화를 하여 강의평가 결과를 객관화하였다. 연구 결과, 출석률과 학업성취도가 높을수록 강의만족도가 높았으며, 주관식 문항에서는 부정 단어보다는 긍정 단어를 더 많이 사용하였고, 학점이 낮을수록 부정 단어를 더 많이 사용하였다. 초급프로그래밍이나 소프트웨어활용군 과목군에서는 출석률이 높을수록 강의만족도가 높았지만, 중급프로그래밍에서는 출석률과 선택형 평가점수는 상관관계가 없었으며 주관식 문항에서도 타 과목군보다 부정 단어를 많이 사용하였다. IT 교과목에 대한 강의평가 경향은 일반 교과목의 강의평가 경향과 유사한 면도 있지만 중급프로그래밍 교과목에서는 대체로 부정적인 평가를 하는 것으로 나타났다.

The modern market is highly competitive. It has progressed from traditional competition between enterprises to competition between supply chains. To ensure that enterprise can form the best strategy consistently, it is necessary to evaluate the trust of other enterprises in the supply chain. First, this paper analyzes the background and significance of supply chain trust research, analyzes and expounds on the qualitative and quantitative methods of supply chain trust evaluation, and summarizes the research in this field. Analytic hierarchy process (AHP) is the most frequently used method in the literature to evaluate and rank criteria through data analysis. However, the input data for AHP analysis is based on human judgment, and hence there is every possibility that the data may be vague to some extent. Therefore, in view of the above problems, this study improves the global trust method based on chain iteration. The improved global trust evaluation method based on chain iteration is more flexible and practical, hence, it can more accurately evaluate supply chain trust. Finally, combined with an actual case of Zhaoxian Chengji Food Co. Ltd., the paper qualitatively analyzes the current situation of supply chain trust management and effectively strengthens the supervision of enterprises to cooperative enterprises. Thus, the company can identify problems on time and strategic adjustments can be implemented accordingly. The effectiveness of the evaluation method proposed in this paper is demonstrated through a quantitative evaluation of its trust in downstream enterprise A. Results suggest that the subjective preferences of and historical transactions together affect the final evaluation of trust.

In this study, long-term global illuminance data for 19 selected cities are calculated from modeled solar radiation data, AEER's TMY2. Perez model in Daysim daylight simulation tool is used for the solar radiation to illuminance conversion. And then, daylight availability in an unit office space is evaluated for the 19 cities. For this evaluation, various daylight performance indices are reviewed since static daylight performance index such as daylight factor (DF) and annual average global illuminance value is not suitable for actual performance evaluation in terms of visual comfort and light energy saving of a space. This study evaluated daylighting performance of prototypical office space module by introducing DA (daylight autonomy) and UDI (Useful Daylight Illuminance) index for major cities of Korea. Result shows that there is upto 18% of illuminance level difference with annual average global illuminance data, but if we consider useful daylight in a space the illuminance level difference among the cities are only within 5%. This means that for sustainable building design especially in daylight design, amount of annual global illuminance is not important factor even in cloudy cities. Daylight design and daylight harvesting system would return similar energy saving impact regardless of building location.

Purpose - We perform an empirical analysis of the effects of global consumer culture positioning (GCCP) in TV advertisements on consumer's brand evaluations (perceived quality, perceived price, and brand prestige) and attitude toward brand. Also, we analyze the moderating roles of consumer characteristics (ethnocentrism and level of product knowledge) in those effects. Design/methodology - This research is based on a survey of 210 randomly-selected university students in Seoul, Korea. The participants in the survey were shown a total of 8 TV advertisements of consumer goods of nondurable goods (fast food and carbonated drinks), and durable goods (sports shoes and digital camera), which included two advertisements for each product where one uses GCCP strategy while another uses LCCP strategy. We estimate the structural model using the AMOS 18.0 computer program. Findings - We find that GCCP has more positive effects on consumers' brand evaluations and attitude toward brand than LCCP in TV advertising. We also find that GCCP has stronger effects on brand evaluation and attitude toward brand in consumers with weak ethnocentrism and in those with a low level of product knowledge. Practical implications - Using GCCP in an advertisement is an effective way of improving consumer's evaluation of the brand and attitude toward the brand mainly when cosmopolitan consumers and consumers with low knowledge levels are segmented as targets. Originality/value - The study contributes to identify how and for what consumer groups' global brand positioning strategies in TV advertisements affect consumers' brand evaluations and their attitudes toward brands.
