Statistical data show that a large aircraft(transport category) is struck by lightning once a year or once per 1,000 ~ 20,000 flight time. The protection design for lightning must be applied to the aircraft because an aircraft is developed on condition that it is absolutely struck by lightning. For the proper protection design, we need to understand direct effect and indirect effect of lightning. This paper described the direct effect of lightning on aircraft's structures and systems.

This study analyzes the impact of Import beer demand on Anti-Japanese sentiment. Recently anti-Japanese sentiment heightened by the media was found to be drastically reducing the consumption of Japanese beer in the domestic imported beer market. Thus, the study used the import demand function of imported beer to analyze the impact of the 'Priming Effect' on the consumption of imported beer by anti-national sentiment, indicating a significant drop in Japanese beer consumption in other countries. Therefore, this study used the imported beer import demand function by country to analyze the impact of the priming effect on imported beer consumption according to anti-national sentiment. As a result, in the case of imported beer consumption in other countries, it was estimated that indirect consumption substitution occurred considerably.

This study was carried out to develop a practical enzyme-linked immunosorbent assay(ELISA) for the determination of soy protein in processed meat products as a preliminary study. The titer of antiserum raised in rabbit by injection of SDS-treated whole buffer extract(WBE) from isolates soy protein(ISP) was above 1:10,000 in indirect ELISA. When the SDS concentration was higher than 0.03% the antibody-antigen reaction was inhibited significantly. However, the antibody-antigen reaction inhibition was not observed when the SDS concentration was less than 0.02%. The antibodies used in this experiment also reacted with renatured antigen after removing SDS by dialysis, though not better than with SDS-denatured antigen(immunogen). The calibration curve with $100\;{\mu}g/100\;ml$ of sensitivity was obtained in indirect competitive ELISA.

Purpose - The purpose of this study is to provide managerial implications for retail brand managers. Specifically, current study divide donation type into direct donation(e.g., corporate philanthropy) and indirect donation(cause-related marketing) and investigate the donation type on the purchase intention. Also, this research intends to provide the mechanism between the donation type on the purchase intention by showing the mediating role of the consumers' perceived warmth. Moreover, the moderating role of the brand type(non-luxury vs. luxury brand) between the donation type, the warmth perception, and the purchase intention will be examined. Research design, data, and methodology - A total of 174 undergraduate students from a university in Korea were recruited and were randomly assigned to the conditions of a 2(donation type: indirect vs. direct) X 2 (brand type: non-luxury vs. luxury) between-subjects design. The hypotheses were tested using SPSS 21.0. Two-way ANOVA and multiple regression analysis were performed. Results - Empirical results showed that the consumers' perceived warmth was higher in the direct donation condition than the indirect donation condition and moreover this influence of the donation type on the perceived warmth was moderated by the brand type. Specifically, the influence of donation type on the perceived warmth was significant only for luxury brand. And there is an interaction effect of donation type and brand type on the purchase intention. More specifically, the purchase intention for luxury brand was higher in the direct donation condition than the indirect donation condition whereas the purchase intention for non-luxury brand was higher in the indirect donation condition than in the direct donation condition. Conclusions - This research contributed to the CSR literature of retail brand management by showing that the influence of the donation type and the brand type on the purchase intention. Moreover, this study enriched CSR literature by introducing Stereotype Content Model and showing the mediating role of the consumers' perceived warmth. Managerially, these results suggested retail brand managers of non-luxury brand and luxury brand how to select an appropriate type of donation and conduct CSR strategies.

In general, empowerment is defined as the motivational concept of autonomy and self-efficacy. Recently, the concept of empowerment is applied to improve organizational staff's job satisfaction and organizational commitment in many organizations. Empower-ment in service organizations, i.e., hospitals, has certainly generated more publicity than any other organizations. The objectives of this study are, first, to measure the degree of hospital employees' empowerment using Spreitzer(1995)'s empowerment theory, second, to analyze the causal relationship of organizational and job characteristics, a degree of empowerment, and organizational performance(job satisfaction and organizational commitment), and third, to offer the strategy for the improvement of job satisfaction and organizational commitment. Spreitzer insists that the empowerment is composed of 4 dimensions(meaning, competence, self-determination, and impact). And he argues that various work-related characteristics is a direct cause of empowerment and the indirect cause of job satisfaction and organizational commitment, mediated by the empowerment latent variable. In order to perform this study, data were collected by self-administered questionnaires from hospital employees working in administrative department of 3 university hospitals in Inchon and Kyunggi-Do region. The number of cases is 181(response rate; 86%). The Collected data were analyzed with SPSS Ver. 10.0 and AMOSV Ver. 4.0. First, to test validity of variables, the factor analysis was used. Second, to test reliability, Cronbach's alpha coefficients was calculated. Cronbach's alpha of empowerment variable is 0.8323 showing that there's no problem in regard to the internal consistency. Also the Cronbach's alpha of other variables are 0.8301 of the degree of perceived control, 0.6705 of job characteristics, O.8787 of compensation, 0.9254 of job satisfaction, and 0.8389 of organizational commitment, respectively. Among the questions of job characteristics, two survey questions are deleted due to lowering the reliability. Third, to test multicollinearity and correlation of variables, the correlation analysis was performed. There was no problem of multicollinearity. Finally structural equation modelling (SEM) analysis was conducted to find the causal relationship of organizational and job Characteristics, empowerment, job satisfaction and organizational commitment. The 16 variables are included for the SEM analysis. The major results of this study are as follows: First, in the case of model fitness, the condition of x$^2$ statistic(92.187) is not fully satisfied, but the indices of GFI(0.912), AGFI(0.863), NFI(0.917) and CFI(0.928) are partially satisfied, which needs to upper 0.90. Second, in the result of hypotheses testing, all hypotheses are accepted and have a positive effect in 95% or 99% confidence interval(P<0.05 or P<0.001) except the effect of compensation variable on empowerment(P=0.082). Third, in regard to the direct, indirect, and total effect of variables, the direct effect of perceived control, task characteristics, and compensation on job satisfaction are 0.728, 2.264, 0.328 and on organizational commitment are 0.094, 1.411, 0.418, respectively. Also the indirect effect of perceived control, task characteristics, and compensation on job satisfaction are 0.311, 0.196, 0.028 and on organizational commitment are 0.210, 0.132, 0.019, respectively. Thus, these findings imply that various work-related factors are direct effect of empowerment and indirect effect of result variables, job satisfaction and organizational commitment. Also These results showed that the workplace empowerment is significant mediating factor of employee's job satisfaction and organizational commitment.

The purpose of this study was to analyze the causal relationship among students' science-related career choice and its factors. The causal relationship was analyzed using structural equation modeling. According to the most fitting model, science career aspiration had a direct and total effect of 0.95 (standardized coefficient) on the science career choice, and personal factor had an indirect and total effect of 0.75 on the science career choice, educational factor, 0.46, and social factor, 0.11. Personal factor had a direct and total effect of 0.79 on the science career aspiration, educational factor with total effect of 0.48 (direct effect -0.21, indirect effect 0.69), and social factor with direct and total effect of 0.12. On the other hand, educational factor had a direct and total effect of 0.72 on the social factor, and a direct and total effect of 0.77 on the personal factor. The difference in the causal effect among grades and between gender was analyzed. The difference was only in the magnitude of influence among grades, showing the same tendency with the total number of students, but the difference between gender was contrastive. For the boys, social factor had the biggest effect on the science career choice, next was personal factor, and the educational factor had the smallest effect. The girls' science career choice influenced mostly from personal factor, and the other two factors' effects were not high. The social effect was negative for the girls' science career choice. The implications of proper science career education were discussed from these results, considering the causal relationship among factors of science career choice and its factors.
