  • Purpose - Most studies related to emotional labor have been conducted in the low-contact service industry rather than the high-contact service industry. Since the subjects of this study were golf service assistants, working in an industry in which the interaction and contact between customers and employees are considerable and the degree of customization is high, this study is significant. Thus, we would like to focus on the relationship between the humor style of golf service assistants and emotional labor. Humor style was divided into two styles-adaptive humor and maladaptive humor. Emotional labor was divided into two dimensions-surface acting and deep acting. In addition, we identify the relationship between emotional labor, job satisfaction, and turnover intention. Research design, data, & methodology - This study focuses on the humor styles in the golf service industry, among golf service assistants, on their emotion labor, and verifies the relationship between emotion labor and work satisfaction or job turnover intention. Based on the outcome, a total of four hypotheses were set up. To verify the hypotheses, surveys were conducted on the golf service assistants working in two golf fields in the region of Busan as well as its neighboring area. A total of 250 copies of the questionnaire were distributed. Subsequently, a total of 227 valid questionnaire copies, after excluding improper responses, were used in the analysis. After verifying the reliability and feasibility of variances, Amos 18.0 was used to implement the structure method so as to verify the study hypotheses. As a result of this analysis, the suitability of the entire model was considerably appropriate to the standard value, and the level is adequate to accommodate the study model completely. Results - First, it was found that the adaptive humor of golf service assistants had a positive effect on deep acting and maladaptive humor had a positive effect on surface acting. Second, It was found that employees' satisfaction with their job was reduced through surface acting, and those employees who experienced positive emotional labor in the form of deep acting were more satisfied with their job. Third, surface acting among employees increased turnover intention, but deep acting reduced it. Finally, the relationship between job satisfaction and the turnover intention of golf service assistants in the golf service industry was examined. Conclusions - First, the adaptive humor of the golf assistants in the golf service industry had a positive effect on their expression behavior. Second, deep acting increased their job satisfaction while their surface acting had a noticeably negative effect on their job satisfaction. Third, the surface acting of the emotion labor dimensions that the golf service assistants experience increases their turnover intention while their deep acting decreases their turnover intention. Finally, when analyzing the relationship between job satisfaction and turnover intention of the golf service assistants, it was found that the turnover intention decreased when their job satisfaction is increased.

  • An amphibious inspection robot system (hereafter AIROS) is being developed to visually inspect the in-containment refueling storage water tank (hereafter IRWST) strainer in APR1400 instead of a human diver. Four IRWST strainers are located in the IRWST, which is filled with boric acid water. Each strainer has 108 sub-assembly strainer fin modules that should be inspected with the VT-3 method according to Reg. guide 1.82 and the operation manual. AIROS has 6 thrusters for submarine voyage and 4 legs for walking on the top of the strainer. An inverse kinematic algorithm was implemented in the robot controller for exact walking on the top of the IRWST strainer. The IRWST strainer has several top cross braces that are extruded on the top of the strainer, which can be obstacles of walking on the strainer, to maintain the frame of the strainer. Therefore, a robot leg should arrive at the position beside the top cross brace. For this reason, we used an image processing technique to find the top cross brace in the sole camera image. The sole camera image is processed to find the existence of the top cross brace using the cross edge detection algorithm in real time. A 5-DOF robot arm that has multiple camera modules for simultaneous inspection of both sides can penetrate narrow gaps. For intuitive presentation of inspection results and for management of inspection data, inspection images are stored in the control PC with camera angles and positions to synthesize and merge the images. The synthesized images are then mapped in a 3D CAD model of the IRWST strainer with the location information. An IRWST strainer mock-up was fabricated to teach the robot arm scanning and gaiting. It is important to arrive at the designated position for inserting the robot arm into all of the gaps. Exact position control without anchor under the water is not easy. Therefore, we designed the multi leg robot for the role of anchoring and positioning. Quadruped robot design of installing sole cameras was a new approach for the exact and stable position control on the IRWST strainer, unlike a traditional robot for underwater facility inspection. The developed robot will be practically used to enhance the efficiency and reliability of the inspection of nuclear power plant components.

  • Purpose - This study empirically analyzes the effect of improvements in the quality of service management performance of college education on traders' conscious change of business management innovation and diverse sales expertise for a year. The use of traders' conscious changes and sales expertise as variables for the verification of the effects of parameters related to the active trader's traditional education market is a desirable direction. The method of research reflects the quality of education service, management result, traders' conscious changes, and sales expertise to understand the precise essence and definition of teaching quality at merchant colleges through theoretical consideration. Moreover, its impact on traders' conscious changes and sales expertise in empirical analysis acts as an intermediary. Research design, data, methodology - The hypothesis of this study leverages the SPSS statistical program. To gather actual proof, sample survey for theoretical research examined 262 valid papers of the 300 papers written by 10 merchants who graduated from merchant's university. First, using the SERVQUAL model, Parasuraman et al. (1996) indicated that for quality of education service, the configuration of factors is the same as the sympathetic performance, that is, responsiveness and empathy, and traders are aware of these elements. However, our preliminary investigation revealed that traders' university education has been excluded as a component of quality of service in the earlier studies. Moreover, we found that certainty of knowledge, reliability, and sympathy are influenced by challenges and by the changing intentions of merchant consciousness. In addition, our study confirms that improvements in convincing abilities and sales technique have a positive impact. Second, merchants' and traders' expertise are proven to affect business performance. In other words, university education of traders and merchants affects the consciousness of consumers, and changes patterns of sales. Third, the quality of service management education and change in the consciousness has a considerable impact on the trader, thereby maximizing business performance and acting as an intermediary for verification. Fourth, the quality of service management education affects the trader's sales expertise to maximize business performance. Results - To summarize, the quality of college educational services relates to the improvement of business performance and the role of the resulting virtuous cycle. Consequently, we can look for suggestions in the traditional markets, where the Government pays attention to the exterior environmental factors as well as to the changing business environment. However, the most important aspect is the merchant awareness. That is, a merchant should understand the distribution environment. Several competitor and trend analyses should be conducted to meet customers' expectations positively and proactively cope with any challenges related to changes. Further, expertise in sales and marketing skills need to be acquired to improve customer convincing abilities and develop a customer-oriented mindset. Conclusions - According to the changes in consumption trends of business enterprises, new management techniques are required to survive competition by improving traditional markets, which will necessitate more competitive education programs in merchant universities.

  • Purpose - The study aims to provide the relationships between the social servicescape and customer's emotion and voluntary behaviors were investigated in this study. The social servicescape was largely divided into service employee's image and other customers (in customer's similarity, physical appearance and suitable behavior). Firstly, the relationship between service employee's image and customer's positive emotion was investigated as a specific purpose of study. Secondly, this study attempted to understand the relationship between other customers (in customer's similarity, physical appearance and suitable behavior) and customer's positive emotion. Lastly, the relationship between customer's positive emotion and customer's voluntary behavior dimension (intention to cooperate, intention to participate in and loyalty) was examined. Research design, data, & methodology - In order to prove the hypotheses in this study, the customers who have experienced family restaurants during the last two months were targeted for a survey. A total number of 300 survey papers were distributed and as a result, 248 papers could be used for analysis, except the papers with insincere answers. After the analysis of the reliability and validity of each major variable, the hypothesis was verified through the structure method by using Amos 20.0. Results - First, the results of hypothesis testing on the relationship between social servicescape and customer's positive emotion showed service employee image gives a positively meaningful impact on customer's positive emotion. Secondly, the results on the relationship between other customers and customer's positive emotion indicated that the customer's similarity and physical appearance has a positively significant impact on customer's emotion while customer's suitable behavior has not a significantly positive impact on customer's positive emotion Lastly, customer's positive emotion was shown to have a significantly positive influence on customer's voluntary behavior dimension, that is, intention to cooperate, intention to participate in and loyalty. Conclusions - This study aims to focus on and emphasize the social servicescape and its importance, which is different from the previous studies that have been focused largely on physical servicescape. Such results in this study indicated the social servicescape (service employee's image and other customers) as an important factor that affects customer's positive emotion and voluntary behavior.
