This study aims to observe the brand personality of foreign airlines and analyze which brand personality best influences service experience satisfaction, price-value satisfaction, and reusing intention. Moreover, it attempts to determine if there is a difference in service experience satisfaction, price-value satisfaction, and reusing intention according to brand personality. A questionnaire was distributed to 1621 consumers; of these, 1500 were used for final data analysis. Results are as follows. First, a factor analysis was used to investigate the brand personality, and three factors were identified: confidence/competence, sophistication, and dynamic. Second, we investigated the influences a brand personality has on service experience satisfaction, price-value satisfaction, and reusing intention. The confidence/competence of a brand personality showed the greatest influence on service experience satisfaction, price-value satisfaction, and reusing intention. Also, price sensitivity satisfaction had the greatest impact on reusing intentions.

The purpose of this study were to investigate the differences of shopping value, promotional affects and product characteristics between buyers and non-buyers, and to examine the most influenced variable on purchasing behaviors of fashion products in CATV home-shopping. We collected data from 595 consumers related to CATV home-shopping in Busan. Data were analyzed by factor analysis, t-test, ${\chi}^2$-test and discriminant analysis. Results showed that there are significant differences between buyers and non-buyers of shopping value demographic characteristics, promotional affects and product characteristics. Especially, shopping value perceived by consumers(e.g., practical value and hedonic value) and product characteristics(e.g., response of others) discriminated whether consumers purchased the fashion products of CATV home-shopping or not. We discussed the implications of results to encourage the purchasing behavior of fashion products in CATV home-shopping.

The design project of a technology product provides an opportunity for students to experience the inter-connectedness of academic information and ill-defined real-world problems. This study focuses on non-engineering students' activity and perception through the assistive technology design project. For this purpose, participants engaged in a team-based technology design project. Then, a qualitative research approach was adopted, which included reflective journals with 24 undergraduate students majored in Adaptive Physical Education. The analysis identified six factors (knowledge value, social value, reality value, accomplishment value, perspective value, benefit value) of perception and five stages (topic selection, function suggestion, visualization, presentation preparation, and presentation) of activity.

볼밸브용 볼의 로봇 육성용접시스템에서 포지셔너의 설계 및 구조강도 해석에 관한 연구를 하였다. 포지셔너의 일부분인 터닝 유닛을 모델링하였고, 보로 가정하여 해석을 진행하였다. 볼의 무게가 $9,000kg_f$ 일 때 터닝 유닛에 가해지는 응력이 366.85MPa로 나왔다. 이 값은 재료의 항복강도보다 높은 값이다. 앞의 결과를 토대로 터닝 유닛을 수정하여 모델링을 하였다. 수정된 모델링으로 해석한 결과, 응력의 값은 296.11MPa로 확인되었다. 이 값은 재료의 항복강도보다 낮은 수치이며, 볼의 무게를 버티는 것을 알 수 있었다.

Results for application of RDF(Refuse Derived Fuel) to selected wastes in metropolitan and small and medium cities are as follows. The physical characteristics of waste are paper, plastic, food waste, and so on. The proximate analysis in P city showed 20.2% of moisture, 71% of combustible material, and 8.8% of ash on annual average. That in G city showed 31.6% of moisture, 59.5% of combustible material, and 8.9% of ash. Ultimate analysis in P city showed 52.04% of carbon, 7.02% of hydrogen, 28.80% of oxygen, 0.66% of nitrogen, and 0.09% of sulfur. Heating value was 3,363 kcal/kg. Ultimate analysis in G city showed 50.85% of carbon, 6.56% of hydrogen, 29.86% of oxygen, 0.79% of nitrogen, and 0.12% of sulfur. Heating value in the G city was somewhat lower than that in the P city with 2,632 kcal/kg. Thus, application of RDF in metropolitan city was more effective than that in small and medium cities. Heating value in mixture for the P city was lower than that in waste of the volume rate waste charge system alone by 143 kcal/kg. In proximate analysis, moisture, and combustible material were likely to be more adequate to RDF.

Background: After the Fukushima accident, the importance of hazard analysis for extreme external events was raised. Methods: To analyze typhoon-induced hazards, which are one of the significant disasters of East Asian countries, a statistical analysis using the extreme value theory, which is a method for estimating the annual exceedance frequency of a rare event, was conducted for an estimation of the occurrence intervals or hazard levels. For the four meteorological variables, maximum wind speed, instantaneous wind speed, hourly precipitation, and daily precipitation, the parameters of the predictive extreme value theory models were estimated. Results: The 100-year return levels for each variable were predicted using the developed models and compared with previously reported values. It was also found that there exist significant long-term climate changes of wind speed and precipitation. Conclusion: A fragility analysis should be conducted to ensure the safety levels of a nuclear power plant for high levels of wind speed and precipitation, which exceed the results of a previous analysis.

This study illucidated the importance of drop Value in the resets of surveying the current values of sizing and grading. Therefore, it is meaningful to get the classification of body form with the appropriate distribution of drop values of the body. The distribution of drop value and the frequency of each form is very helpful to name the combined sizing or coverage of ready-made clothes. This study aimed at classifying body forms with various drop values using multivariate analysis for sizing and grading. Factor analysis and cluster analysis were done using measured values from unmarried women. The resets are as follows; The factor which explains body forms was obtained by factor analysis, and the representative major 18 items which have important roles in classifying body forms were selected among the measured values with high factor loading and communality. 1) The body forms were classified into 3 groups based on the characteristics, frequencies and distributions of them obtained from cluster analysis. 2) Each classified body form showed conspicuous difference in drop value and the difference of body form mainly resulted from the difference between bust and hip(drop value) in Korean unmarried women. 3) Discriminant analysis showed that the most significant discriminant factor of the trunk classification were bust circumference, upper bust circumference, hip circumference and stature. 4) The cover ratio of size studied in this study for the Korean Sizing system for women's garment were founded high.

In this paper, crack detection method using eigen value analysis is presented. Three methods are used: theoretical analysis, finite element method with the cracked beam elements and finite element method with three dimensional continuum elements. Finite element formulation of the cracked beam element is introduced. Additional term about stress intensity factor based on fracture mechanics theory is added to flexibility matrix of original beam to model the crack. As using calculated stiffness matrix of cracked beam element and mass matrix, natural frequencies are calculated by eigen value analysis. In the case of using continuum elements, the natural frequencies could be calculated by using EDISON CASAD solver. Several cases of crack are simulated to obtain natural frequencies corresponding the crack. The surface of natural frequency is plotted as changing with crack location and depth. Inverse analysis method is used to find crack location and depth from the natural frequencies of experimental data, which are referred by another papers. Predicted results are similar with the true crack location and depth.
