  • This research develops dispatching rule for a wafer FABs with dedication constraints. Dedication, mostly considered in a photolithography step, is a feature in a modern FABs in order to increase the yield of machines and achieve the advance of manufacturing technology. However, the dedication has the critical problem because it causes dedication load of machines to unbalance. In this paper, we proposes the dedication load based dispatching rule for load balancing in order to resolve the problem. The objective of this paper is to balance dedication load of photo machines in wafer FABs with dedication constraint. Simulation experiments show that the proposed rule improves the performance of wafer FABs as well as load balance for dedication machines compared to open-loop control based conventional dispatching rule.

  • Purpose The purpose of this study is to investigate which decision factors continue to use the service based on the online simple payment service. In this study, we will examine how to activate the service from the continuing factors through the dual-model theory consisting of personal dedication and constraint dedication which are frequently used in relation marketing. Design/methodology/approach In this study, we investigated the activation of online simple settlement service using factors affecting the preference of the simple payment service based on the dual-model of dedication-based mechanism and constraint-based mechanism. Findings This study confirmed that customer satisfaction and convenience under the dedication -based mechanism were found to be linked to the preference of the simple payment service. Switching cost under the constraint - based mechanism showed that the customer had no binding ability to continue using the service of the current provider. Likewise, preference was found to have a direct effect on the actual frequency of use of the simple payment service, the number of uses compared to the total number of online payments, and willingness to use more.

  • The purpose of this study was to obtain data to improve customer orientation by managing emotional labor in foodservice employees. This study investigated the correlation between emotional labor (surface acting, deep acting), job burnout (emotional exhaustion, cynicism), and job engagement (vigor, dedication, absorption) in high school foodservice employees, and how they affect customer orientation. Our survey was administered to 330 school foodservice employees in the Busan area from June 2 to June 27, 2015. A total of 321 questionnaires were used for final analysis. The mean values for deep acting (p<0.01), cynicism (p<0.01), and dedication (p<0.05) significantly according to the position of the emproyees. The mean customer orientation significantly according to employment status (p<0.01) and meal service time (p<0.01). There was positive correlation (p<0.01) between surface acting, and emotional exhaustion cynicism, but negative correlation (p<0.01) between surface acting and vigor, dedication, absorption, and customer orientation. Deep acting had negative correlation (p<0.01) with emotional exhaustion and cynicism, positive correlation (p<0.05) with vigor, dedication, absorption, and customer orientation. Surface acting had negative influences on emotional exhaustion and cynicism, cynicism had negative influences on vigor, dedication, absorption, and customer orientation. Deep acting had positive influences on absorption and customer orientation, absorption had positive influences on customer orientation. Thus, nutrition teacher(dietitian) should educate foodservice employees the positive effects of deep acting to change their surface acting to deep acting, while actively managing internal customers.

  • The opening of a second new airport is urgently needed to meet the growing number of visitors to Incheon International Airport. This study focused on effectiveness of mediating effects on the dedication to organization in order to determine why manpower resources of the airport service sector should take job-changing into account and to focus on staff who provide service to customers visiting Incheon International Airport management of airport service quality by providing a better service and preventing them from leaving their job. The results show that, first, only obligation conflicts and heavy workload affect the dedication to organization in terms of task-related causes. Second, compensation and relationships with seniors also affect the dedication to organization in terms of organization-related causes. Third, if more dedication is required, more employees will leave their job. Fourth, role conflict is the only reason to leave the job related to task. Fifth, only compensation and decision making affect the cause of the dedication to organization. The employer urgently needs to make a system to develop a relationship with colleagues and seniors, make a better work environment so that employees can work for a longer period and monetary or valuable compensation should be provided as indicated above in order to keep them employed.

  • Most of the IS continuance research has assumed that IS use is activated by an intention to use, which in turn is determined by the evaluation of IS usage. Perceived usefulness is one of the evaluation variables most widely used. Typically, the past studies adopt this perceived usefulness because it views continuance as an extension of acceptance behavior. However, the literature on interpersonal relationships suggests that individuals are motivated to maintain relationships either because they genuinely want to or they believe they have no other option. The former is referred to as dedication-based relationship maintenance and the latter as constraint-based relationship maintenance. The IS continuance can be considered as the relationship maintenance situation with the existing IS that the user is currently using. The belief constructs previously used in IS continuance researches fall into the category of dedication-based ones. Additional constraint-based belief constructs are needed to explain the IS continuance behavior. In this regard, switching cost represents an important avenue for better understanding and predicting customer retention in that it can be regarded as the constraint-based motivation for relationship maintenance or IS use continuance. For an empirical exploration, 275 samples were collected from the users of a web portal site. Data analysis using Structural Equation Modeling (SEM) shows that perceived usefulness shows a significant direct effect on continuance intention while perceived switching cost significantly affects continuance usage.

  • In the past, the analog protection relays have been widely used for the safety-related systems in the nuclear power plants due to their stability and reliability. Meanwhile, as the high performance digital system has been developed, the digital systems have been adopted in the non-safety systems. However, since the digital systems currently used in the non-safety systems were not developed according to Q-class standard, Commercial Grade Item Dedication (CGID) procedure should be performed in order to apply them to the safety-related system. The purpose of this paper is to describe the CGID procedure including the analysis of the hardware architecture as well as the software embedded in protective relay to apply to the emergency diesel generator in the nuclear power plant. The entire CGID procedure was performed strictly according to the international standard and regulations.

  • The purposes of the study were to assess levels of burnout, engagement, and turnover intention of dietitians and chefs and to investigate the relationships among the antecedents and consequences of burnout and engagement. A total of 257 dietitians and chefs at a contract foodservice management company in Korea were surveyed using a self-administered questionnaire. Burnout (exhaustion, cynicism, and professional efficacy) and engagement (vigor, dedication, and absorption) were measured with three dimensions each. The dietitians showed significantly higher exhaustion (p < .05) and significantly lower vigor and dedication than the chefs (ps < .05). The exhaustion and cynicism dimensions of burnout were negatively correlated with all three dimensions of engagement (ps < .001) and positively correlated with turnover intention (ps < .001). The professional efficacy was positively correlated with all three engagement dimensions (ps < .001), but not with turnover intent. In addition, turnover intention was positively correlated with negative affectivity and work-load and negatively correlated with vigor, dedication, and absorption. A series of hierarchical regression analyses were conducted to assess the effects of the personal (positive and negative affectivity) and situational factors (workload, interpersonal conflict) and job stresses on turnover intention. After removing the effects of the personal and situational factors, cynicism (p < .01) was the only significant predictor of turnover intention. Based on the findings, suggestions for recruiting and retaining qualified and motivated employees were provided.
