Let N be a $II_1$ factor and G be a finite group acting outerly on N. Then the crossed product algebra $M = N \rtimes G$ is also a $II_1$ factor and $N' \cap M = CI$, i.e. N is irreducible in M. Moreover, N is regular in M, in other words, M is generated by the normalizer $N_M (N)$.

The purpose of this study was to provide basic information to school foodservice employees so that they can meet their professional responsibilities by understanding the relationship of job burnout, job engagement, job stress and level of job satisfaction and analyze the influence between these factors according to the general characteristics of the employees. The subjects included employees at 426 school foodservices in Busan. The mean job engagement was significantly different in the reason that cooks chose this profession(p<0.05), and readiness to quit(p<0.001). The mean job stress was significantly different in different age groups(p<0.01), cooking certification(p<0.01), reason that cooks chose this profession(p<0.01), and readiness to quit(p<0.05). The mean job stress was significantly different in the reason cooks chose this profession(p<0.01), and readiness to quit(p<0.05). In terms of the level of satisfaction of coworkers, the subfactor of job burnout, 'self-confidence' and 'achievement' had positive influences (p<0.01) and for the level of satisfaction of the work, it had positive influences on 'achievement'(p<0.01) and negative influences on 'exhaustion' (p<0.01). In terms of the level of satisfaction of co-workers and work, the subfactor of job engagement, 'absorption' had positive influences(p<0.01). Among the level of job satisfaction, for the level of satisfaction of pay, the subfactor of job stress, 'unstable job' had negative influences(p<0.01) and 'role conflict' had positive influences(p<0.05). For the level of satisfaction of co-workers, the subfactor of job stress, 'role conflict' had negative influences(p<0.01), and for the level of satisfaction of work, 'inappropriate circumstance' and 'unstable job' had negative influences (p<0.01).

The purpose of this study was to investigate the effects of coach confidence on member satisfaction and perceived performance in throwers. The participants were 198 throwers who were competed in the 40th National Athletics Championship. To analyze the data, multiple regression was performed using SPSS 18.0 ver Windows. The results showed that coach confidence of throwers affected significantly on the athlete satisfaction(p<0.05). In other words, the subfactor of coach confidence such as integrity, ability, consistency, sacrifice, and openness affected the subfactor of player satisfaction such as technical analysis, teaching ability, and coaching qualification. And also, coach confidence of throwers affected significantly on the perceived performance(p<0.05). The subfactor of coach confidence such as integrity, ability, consistency, sacrifice, and openness affected the subfactor of player satisfaction such as victory will and skill exhibition. It was concluded that the coach confidence of throwers may affect player satisfaction and perceived performance.

This study is to investigate the impact of emotional intelligence of online shopping mall call center counselor on customer orientation. The SPSS 25.0 ststistics program was applied for the empirical analysis 148(87.05%)of 170 copies are used for final data analysis. The implications of results are as follows. First, use of emotion, a subfactor of emotional Intelligence, has shown to have a significant positive effect on customer orientation. Second, other's emotional appraisal, a subfactor of emotional Intelligence, has shown to have a significant positive effect on customer orientation. Third, self emotional appraisal, a subfactor of emotional Intelligence, has shown to have a significant positive effect on customer orientation. Fourth, regulation of emotion, a subfactor of emotional Intelligence, has shown to have a significant positive effect on customer orientation.

Likelihood of failure (LOF) for the external corrosion of stainless steel, which affect to a risk of facilities, was analyzed quantitatively through the risk based inspection using API-581 BRD. We found that the technical module subfactor (TMSF) decreased as the inspection number increased and it increased as the inspection effectiveness and the used year increased, and that the TMSF showed high value for the case of the marine/cooling tower drift area as a corrosion driver, In this condition, the LOF for the external corrosion of stainless steel had lower than that for the carbon and low alloy steels

Likelihood of failure for the external corrosion of carbon and low alloy steels, which affect to a risk of facilities, was analyzed quantitatively through the risk based inspection using API-581 BRD. We found that the technical module subfactor (TMSF) decreased as the inspection number increased and it increased as the Inspection effectiveness and the used year increased. In this condition, the TMSF showed high value for the case of the marine/cooling tower drift area as a corrosion driver, poor quality of coating, no insulation, and low insulation condition.

The likelihood of failure by the corrosion of high temperature $H_2S/H_2$, which affect to a risk of facilities, was analyzed through the risk based-inspection using API-581 BRD. We found that the corrosion rate was increased as temperature and $H_2S$ concentration were increased. Also, the technical module subfactor(TMSF) was increased as an used you increased, material thickness decreased, inspection number decreased, and inspection effectiveness increased. In these conditions, the maximum value of TMSF was not varied, but the TMSF was sensitively varied at low temperature for high concentration of $H_2S$.

The likelihood of failure for the stress corrosion cracking (SCC) of caustic cracking, which affect to a risk of facilities, was analyzed through the risk based-inspection using API-581 BRD. We found that SCC of the caustic cracking was occurred above 5 % NaOH concentration, and the technical module subfactor (TMSF) was maximized for above 50 % concentration. The heat traced and monitoring were not sensitive to the TMSF with NaOH concentration and temperature. But the steam out was more of less affect minimum value of the TMSF. Also, the inspection number, the inspection effectiveness, and the year since inspection were very sensitive to the TMSF with NaOH concentration and temperature. Therefore, the plan of next inspection will be established with compositively considering those at once.

The likelihood of failure for the thinning of high temperature sulfide and naphthenic acid corrosion, which affect to a risk of facilities, was analyzed through the risk based inspection using API-581 BRD. We found that the corrosion rate was increased with increasing temperature and total acid number(TAN). And maximum value of the technical module subfactor(TMSF) was not varied with operating condition, but the TMSF was sensitively changed at the range of low temperature, low flow rate, and high TAN. Also, the TMSF was increased as an used year and inspection effectiveness increased, but it was increased as thickness, inspection number, and over design decreased.

Purpose: This research is the impact of service quality of Economy Hotels on customer satisfaction and Re-visit Intention in China. It reviews the empirical theories about Economy Hotels at home and abroad, based on SERVPERF, combines with the actual situation of China's Economy Hotels, and then constructs based on the research results at home and abroad. In the subfactor of service quality, "recovery" is added, and the relationship model between the service quality of Economy Hotel, customer satisfaction and Re-visit Intention is designed, in which the mediated effect of "customer satisfaction" between the service quality's subfactor and Re-visit Intentio is explored. Methods: 334 questionnaires were distributed to the check-in guests of three Home Inns in China's first-tier cities (ShangHai,BeiJing,ShenZhen), of which 300 were valid for data analysis. Result: The data analysis results show that the Economy Hotels' subfactor of service quality have a positive impact on customer satisfaction and Re-visit Intention, and customer satisfaction also plays an mediated effect. (partial mediation: tangible, reliability, recovery; full mediation: responsiveness, assurance, empathy) Conclusion: The research puts forward the enlightenment points for the development of Economic Hotels through the differences in the development emphasis and service quality between Economic hotels and other types of hotels, so as to improve the satisfaction and market competitiveness of China's Economic hotels through the research results.
