제8차 전력수급기본계획에 근거하여 현재 운영중이거나 계획중인 원자력발전소에서 발생할 사용후핵연료의 양과 특성을 추정하였다. 본 연구에서 고려된 특성은 핵연료집합체에 대한 제원, 핵연료봉 배열, 235U 초기 농축도, 방출연소도, 냉각기간이다. 이들은 사용후핵연료 처분시스템을 설계하는데 필수적인 항목이다. 2082년까지 가압경수로 사용후핵연료의 예상발 생량은 약 62,500 다발로 추정되었다. 2018년 말까지 발생한 사용후핵연료 중 상대적으로 길이가 짧은 웨스팅하우스형 원전 연료가 약 60%, 상대적으로 길이가 50 cm 정도 긴 한국형 원전 연료가 약 40%를 차지하였다. 235U 초기 농축도 4.5 wt% 이 하를 갖는 사용후핵연료의 비율은 전체 발생량의 약 90%를 차지하였으며, 방출연소도는 98%의 물량이 55 GWd/tU 이하로 나타났다. 2077년을 기준으로 웨스팅하우스형 원전에서 발생한 사용후핵연료의 냉각기간은 50년 이상이 97% 정도를 차지하였으며, 본 논문에서 가정한 처분 완료시점인 2125년을 기준으로 한국형 원전에서 발생한 사용후핵연료의 냉각기간은 45 년 이상이 98% 정도를 차지하는 것으로 나타났다. 이러한 결과를 바탕으로 효율적인 처분시스템 설계를 위해 기준 사용후 핵연료는 제원적 특성을 고려하여 두 가지 형태로 설정하였으며, 웨스팅하우스형 원전 연료의 경우, 집합체 제원으로 KSFA, 초기 농축도 4.5 wt%, 방출연소도 55 GWd/tU, 냉각기간 50년으로, 한국형 원전 연료의 경우, 집합체 제원으로 PLUS7, 초기 농축도 4.5 wt%, 방출연소도 55 GWd/tU, 냉각기간 45년으로 설정하였다.

목적 : 영상의 특성이 안구 움직임에 미치는 영향을 분석하기 위해 아이트래커를 이용하여 안구움직임을 측정 하였다. 방법 : 본 연구의 취지에 동의하는 성인남녀 64명(24.44±3.68세)을 대상으로 선정하였다. 재생시간이 30분인 4개의 영상물을 시청하도록 하고 아이트래커를 이용하여 눈깜박임 횟수, 동공직경, 주시 횟수 및 홱보기 횟수를 측정하였다. 피사체 움직임의 정도가 서로 다른 2개의 영상물(액션 및 토론)을 고화질 및 표준화질로 각각 제작하여 상대적 움직임 및 화질의 차이를 구분하였다. 결과 : 액션 영상을 시청할 때 토론 영상의 시청과 비교하여, 동공직경이 더 컸고(p<0.050), 눈깜박임 횟수는 더 적었고(p<0.050), 주시 횟수는 더 많았고(p<0.050), 홱보기 횟수는 더 많았다(p<0.050). 그러나 화질에 따른 안구 움직임은 유의한 차이가 없었다. 결론 : 영상의 종류에 따라서 눈깜박임, 동공직경, 주시 횟수 및 홱보기 횟수의 차이를 발견하였다. 따라서 영상의 특성이 안구운동 요소에 영향을 미치는 것으로 생각된다.

본 연구는 비시장평가법인 조건부가치평가법을 통해 수질개선을 위한 지불용의액을 추정 하였다. 연구 지역은 심각한 수질오염으로 직·간접적인 피해를 입고 있는 베트남의 하노이 To Lich 강 유역이며, To Lich 강 주변의 거주민들을 대상으로 설문조사를 실시하였다. 이중양분선택형 질문을 통해 설문 내용을 디자인하였고, 설문조사를 통해 얻어진 표본으로 이변 량프로빗모형을 사용하였다. 그 결과, 베트남 하노이지역의 거주민이 수질개선을 위하여 연간 지불용의액은 약 VND 202,560원으로 나타났다. 또한 지불용의액에 영향을 주는 중요한 변수는 사회경제적 변수로 나이, 소득으로 나타났고, 거주민의 건강에 대한 관심도 통계적으로 유의한 변수로 나타났다. 본 연구는 하노이의 To Lich 강에 조사 지역을 한정하여 진행하였기 때문에, 연구 지역 범위를 확대시켜 향후 연구가 진행 되어야 할 것이다. 본 연구의 결과는 지속 가능한 수질 관리의 중요성을 강조하며, 추후 베트남 수질 개선 정책에 환경적 편익 정보를 제공하는데 도움을 줄 것으로 기대된다.

Looking at recent safety accidents in buildings, most of them due to lack of FM expertise, and this is due to human resources. In each all industry areas, some companies are competitive, representational, and leading in the market through long-term expertise and research in their respective fields. In the field of FM industry, some companies offer core-competencies in internal and external innovative building management through competition with others. However, old custom and old management form still exist in the FM field. However, an old custom and old management system still exist in the FM field; it forces cost-cutting and caused by carelessness in technical development competitiveness and safety measures. The government control by safety inspection and facility inspection through legislation of building management, but the management is still weak as a side of in the facility management section due to inspect sth as a mere formality and submit a paper report. These facts exist different kind of usage of the building have a three-party encounter between a building owner, user, and FM enterprises. In this research identify survey, especially building owner (manager)’s choice perception priority for optional factors to choose FM enterprises. Based on this, FM enterprises will be forced to seek a new dimension for better building management. In this light, the purpose of the research is to shape changes in the FM market culture safely and providing better service in building management and understanding building owner's insight through this research's information.

The purpose of this study is to design a Japanese language class based on the analysis of college students’ assignments and their misuses of ‘can’ expressions in them during a Japanese conversation class. In the class, the assignments required the students to record their thoughts about conversation topics. For the assignments, the instructor tried to transcribe the students’ recordings, find their misuses of ‘can’ expressions and provide some corrective feedback for the misuses. Following the feedback, the students were asked to resubmit their recordings and then, the instructor examined their recordings again focusing on ‘can’ expressions. The findings from the students’ first recordings revealed that the students used some verbs that describe ‘possibility’ at first, and gradually they used more ‘surukotogadekiru(=can)’ expressions. Then, finally, the students tended to use both ‘possibility’ verbs and ‘surukotogadekiru(=can)’ expressions regardless of the students’ proficiency levels. However, by comparing to the students’ second recordings, the use of ‘possibility’ verbs increased while the use of ‘surukotogadekiru(=can)’ expressions decreased in the second recordings. Based on the findings, a class design that can be applicable to the Japanese language conversation classes was suggested.

The purpose of this study is to analyze the factors influencing consumers purchasing of domestic, imported and craft beer through AHP analysis and to provide implications for marketing for each beer market. In this study, theories and calculations related to AHP analysis were thoroughly examined and selection attributes were determined by referring to existing theories. A total of 164 consumers who have purchased beer were the target of the survey. The results were analyzed by AHP analysis and the differences were analyzed. It was confirmed that the domestic, imported, and craft beer had the highest weight in the taste in the first layer. At this time, we can confirm that imported, and craft beer has a relatively high weight on taste and domestic beer has a relatively high weight on brand image. We also found that design and advertising images do not have a significant impact on beer selection. Even though it is study on beer, we can find people have different preference between their orgin. In this study, it is possible to show what type of factors does the beer manufacturing and distribution company should concentrate on by analyzing factors that consumers consider, unlike other studies focusing on consumption status of existing beer.

The study had subject to find out what factors Korean automobile consumer is considering in their decision to purchase cars in the situation of the growing competition in the domestic automobile market. In order to this end, the previous study was reviewed to select various factors considered in the process of buying cars. Based on this, Analytic Hierarchy Process was used to prioritize which factors were considered more important by consumers. In the result of study, we could find that performance had the highest priority, and the second ranking was the price. In contrast, image of brand and convenience of maintenance were shown to be relatively low in importance, ranking 3rd and 4th, respectively. Beside, we could recognized the ranking of other detailed factors. This study has an academic implication in that it is able to grasp the latest tendency of consumers’ purchase choice of car and to make conclusion by applying AHP analysis method to study of related subject. It also have practical significance that can be a basis for make sense what factors should be taken by the automobile industry to uprise the purchase of the consumers through the identification and preparation of the purchase selection criteria of domestic automobile buyers.

This study investigates passenger-authored online reviews of airline services using social network analysis to compare the differences in customer perceptions between full service carriers (FSCs) and low cost carriers (LCCs). While deriving words with high frequency and weight matrix based on the text analysis for FSCs and LCCs respectively, we analyze the semantic network (betweenness centrality, eigenvector centrality, degree centrality) to compare the degree of connection between words in online reviews of each airline types using the social network analysis. Then we compare the words with high frequency and the connection degree to gauge their influences in the network. Moreover, we group eight clusters for FSCs and LCCs using the convergence of iterated correlations (CONCOR) analysis. Using the resultant clusters, we match the clusters to dimensions of two types of service quality models (Grönroos, Brady & Cronin (B&C)) to compare the airline service quality and determine which model fits better. From the semantic network analysis, FSCs are mainly related to inflight service words and LCCs are primarily related to the ground service words. The CONCOR analysis reveals that FSCs are mainly related to the dimension of outcome quality in Grönroos model, but evenly distributed to the dimensions in B&C model. On the other hand, LCCs are primarily related to the dimensions of process quality in both Grönroos and B&C models. From the CONCOR analysis, we also observe that B&C model fits better than Grönroos model for the airline service because the former model can capture passenger perceptions more specifically than the latter model can.

Quality management has become an pervasive philosophy in most sectors of business. Specific movements such as statistical quality control, quality circle, total quality management, and quality management system have become embedded in business organizations. Only the companies with competitive edge can survive in the competition in global market. KSA(Korean Standards Association) established in 1962 has launched all kinds of quality education, quality standard certification service for business, and KNQA(Korean National Quality Award) system. This article considers quality competitiveness excellent company award among KNQA. We performed a statistical analysis of audit data for quality competitiveness excellent company for three years, from 2015 to 2017. By using ANOVA and two sample t-tests, the average scores of 13 evaluation fields were significantly different depending on company size and type. We proposed ways to improve the current hall of fame system. We discovered that the average scores of 13 evaluation fields in the audit data according to years and hall of fame status were not significantly different. We also showed linear relationships among 13 evaluation fields by correlation analysis and obtained an estimated linear regression equation : Business Performance, which is a comprehensive index, as a dependent variable was significantly related to Customer Focus and Product Liability as regressor variables among 13 evaluation fields by regression analysis.
