Field monitoring techniques offer an attractive approach for understanding bridge behavior under in-service loads. However, the investigations on bridge behavior under high-speed train load using field monitoring data are limited. The focus of this study is to explore the structural behavior of an in-service long-span steel truss arch bridge based on field monitoring data. First, the natural frequencies of the structure, as well as the train driving frequencies, are extracted. Then, the train-induced bearing displacement and structural strain are explored to identify the effects of train loads and bearings. Subsequently, a sensitivity analysis is performed for the impact factor of strain responses with respect to the train speed, train weight, and temperature to identify the fundamental issues affecting these responses. Additionally, a similar sensitivity analysis is conducted for the peak acceleration. The results indicate that the friction force in bearings provides residual deformations when two consecutive trains are in opposite directions. In addition, the impact factor and peak acceleration are primarily affected by train speed, particularly near train speeds that result in the resonance of the bridge response. The results can provide additional insight into the behavior of the long-span steel truss bridges under in-service high-speed train loads.

This study investigated and compared the brand personality of domestically run family restaurants with quick service restaurants. Information was elicited from respective patrons using self-administered questionnaires which asked questions on recognizable brand characteristic and attributes of each restaurant through image maps. Data from the self-administrated questionnaires were collected and analysed using comparative statistical analysis, including frequency, t-test, chi-square, factor analysis, reliability analysis and correspondence analysis. Overall, patrons identified 5 factors which they used to rank individual restaurants; sophistication, competence, likeableness, trendiness, and ruggedness. Overall results showed the family restaurants that scored highly on likeableness and trendiness were Outback and TGIF. Furthermore, Vips was the only family restaurants that scored highly in ruggedness. In relation to quick service restaurants, Lotteria scored highest for competence while McDonalds and Burger King scored best for sophistication. Limitations and future research directions are also discussed.

기존의 박물관 중심의 연구에서 활용되어온 서비스품질 측정지표들이 미술관의 서비스품질 측정 및 서비스 개선방안 연구에 여과 없이 사용됨에 따라, 미술관 고유의 서비스 특성과 이에 따른 적절한 개선안을 도출하지 못하는 문제가 있었다. 이에 본 연구는 미술관의 특성을 고려한 서비스 척도를 개발하고, 이들이 방문객 만족도 및 재방문에 미치는 영향을 분석하여, 미술관의 서비스품질 개선에 도움이 되고자 하였다. 광주시립미술관을 방문한 관람객을 대상으로 설문조사하였으며 요인분석 및 회귀분석을 실시하였다. 그 결과 미술관의 서비스품질 요인은 전시방법, 직원서비스, 전시내용, 미술관시설, 부대프로그램 등 5개 요인으로 구분되었다. 이러한 서비스품질 요인 가운데 전시내용이 미술관 재방문이나 추천의도, 전반적 만족에 가장 큰 영향을 미친 것으로 나타나 전시내용에 대한 만족도가 높을수록 재방문 의도와 추천 의도가 높아지는 것으로 분석되었다. 또한 부대프로그램은 재방문의도에 전시내용 다음으로 큰 비중을 차지하는 것으로 나타났다. 결국, 미술관의 고유한 기능인 전시이외에도 교육, 체험, 여가의 요소들이 복합된 다양한 부대프로그램이 미술관의 서비스 질을 높이고 방문객의 만족도 및 재방문율을 높이는 것으로 이해할 수 있다. 본 연구는 미술관을 대상으로 하는 실증적 연구를 통해 미술관의 서비스 연구에 필요한 서비스품질 척도들을 검증했으며, 이를 바탕으로 만족도와 행동의도에 미치는 영향을 파악하였다는 점에서 학술적 의의를 가진다. 나아가 미술관 경영 및 마케팅 담당자들에게 전시내용 및 부대프로그램 개발이라는 서비스품질 향상을 위한 핵심적인 요소들을 제안하고 있다는 점에서 공헌이 있을 것으로 판단된다.

The master plan of forest land management proposes forest watershed management that considers regional characteristics in order to overcome the problem of uniform forest land management. In order to manage the forest watersheds in Gyeonggi-do, this study classified 1,823 forest watersheds in Gyeonggi-do and attempted to understand their characteristics. It conducted a factor analysis and cluster analysis from the perspective of conservation value and development pressure using forest land indicators. In terms of conservation value, three factors were drawn: the topography factor, vegetation factor and public service factor, while in terms of development pressure, three factors were drawn: the easiness of development factor, economic benefits factor and development activity factor. Using these factors, forest watersheds were divided into three clusters in terms of conservation value while they were divided into three clusters in terms of development pressure. Using the results of the cluster analysis from a conservation-development perspective, the forest watersheds were classified into nine different types, and the characteristics were identified by each type. It is judged that the factors and clusters drawn as a result of the research accurately reflect the present conditions of Gyeonggi-do, and the nine types of forest watersheds have clear characteristics according to each type, which are judged to be utilized in forest management in the future.

This paper discussed about business ethics and innovation management performance of IT service firms in Korea. To prove empirically the research hypothesis, the statistical analysis was based on the response from the 92 IT Service firms in Korean. As analysis results, it was found that the business ethics of organizations were the effect factors of the innovation management performance. And the knowledge competency and creativity are confirmed as a mediator between the business ethics and innovation management performance. So this paper suggests that business ethics in organizations are the important factor for enhancement of IT service firm's innovation performance. Specially the mediation effects of knowledge competency and creativity variables were proved empirically for the relation between the business ethics and innovation management performance. So it is desirable that knowledge-based service firms, for example IT service firms, have to strive to upgrade their level of business ethics and to link with their creativity and knowledge competency.

The data were collected from 212 female adults using questionnaire. Using SPSS package, Cronbach's α, factor analysis, and multiple repression analysis were performed. The results could be summarized as follows. 1. The service quality of internet apparel shopping mall was perceived as reliability, advantage, responsibility, product assortment, tangibles, and rapidness. 2. For perceived risk, privacy risk, economic risk, delivery risk, size risk, and quality risk were investigated. The perceived risk except economic risk and web search ability had an effect on the service quality of internet apparel shopping mall. 3. The most of perceived risk, web search ability, and advantage of the service quality had an effect on the shopping intent of the internet apparel shopping mall.
