  • This study analyses and discusses on the characteristic and the origin of the exhaustion method caused by the controversy over whether that method succeeded to the Antiphone's complete exhaustion idea and whether that method is similar to the method of limits. First, this study analyses 'principle of exhaustion method' which play an important role in that method in order to grasp the local characteristic of it. And this study speculates the origin of the exhaustion method by considering the time and situation of appearance and looking through the local characteristic of it. Also, this study takes a view of the overall characteristic of the exhaustion method by inquiring into the process of actual application of 'principle of exhaustion method' in a proof. As these results, this study reveals that the exhaustion method uprose not as a succession of Antiphone's idea but as a reaction to its idea, and that the exhaustion method has the recognized character of 'finitude' as distinct from the method of limits.

  • The purpose of this study was to understand the process and investigate basic theory of fatigue experience of shift work nurses. The present study adopted grounded theory methodology on fatigue of shift work nurses. The participants for this study were 15 shift work nurses who were in the age of 25 to 35, the clinical experience of 2 to 14 years and the work department of ICU. ER. ward and delivery room. The data were collected from 2000 to 2003 by using interviews and observations. The contents of the interviews were tape-recorded and were drawn through repeated method. And then were analyzed into the concept, subcategories, and categories with the open coding process and axial coding was done to identify the relationships of the concepts and categories according to the paradigm models. The core category generated, which was a central phenomena of the exhaustion process. The causal condition is change events. The central condition of exhaustion were sorted as physical discomfort, decreasing vigor, psychological instability, feeling of sleeping desire, changing face impression and being heavy body. The intervening condition were discovered as social$\cdot$ psychology$\cdot$physical resist and positive$\cdot$negative interaction strategies. The consequences of the fatigue process is the short term exhaustion relief and long term residual exhaustion. The fatigue process of this study was 'break through exhaustion' of change event-exhaustion-resist-resolve intervention-adaptation. This study offers better understanding on fatigue process of shift work nurses and may facilitate more appropriate interventive strategies to support, information and knowledges according to fatigue process.

  • In this paper, the effects of low temperature plasma (LTP) treatment on the dyeing properties of the wool fiber were studied. The wool fibers were treated with oxygen plasma and three types of dye that commonly used for wool dyeing, namely: (i) acid dye, (ii) chrome dye and (iii) reactive dye, were used in the dyeing process. For acid dyeing, the dyeing rate of the LTP-treated wool fiber was greatly increased but the final dyeing exhaustion equilibrium did not show any significant change. For chrome dyeing, the dyeing rate of the LTP-treated wool fiber was also increased but the final dyeing exhaustion equilibrium was only increased to a small extent. In addition, the rate of afterchroming process was similar to the chrome dyeing process. For the reactive dyeing, the dyeing rate of the LTP-treated wool fiber was greatly increased and also the final dyeing exhaustion equilibrium was increased significantly. As a result, it could conclude that the LTP treatment could improve the dyeing behavior of wool fiber in different dyeing systems.

  • Companies are making design changes by improving product quality and function to succeed while meeting customer requirements continuously. Design changes are changing the product BOM's amount, item, specification, and shape while causing a change in the product's structure. At this time, the problem of inventory exhaustion of parts before design change is a big topic. If the inventory exhaustion fails, the pieces before the design change become unused and are discarded, resulting in a decrease in asset value, and the quality cost of the design change affects the company's profits. Therefore, it is necessary to decide to minimize quality costs while minimizing waste inventory costs at the time of application of design changes. According to the analysis, priorities should be prioritized according to urgency because the quantity of items before the design change affects the applied lead time.

  • Purpose: This research was conducted to investigate the characteristics of emotional exhaustion that Korean school nurses suffer, to suggest policy implications to address this issue, and to propose preventive and supervisory measures regarding emotional exhaustion experienced by school nurses in elementary, middle, and high schools in Korea. Methods: A survey was conducted under the authorization of Chungcheongnam-do Office of Education. Out of 400 copies first distributed, 376 copies were returned. Among the 376 copies, 117 copies which were judged insincere or from teachers with less than 1 year of experience were exclded from the study. Through this process, only 259 copies were finally selected. Results: As a result of assessing the fit of the model, it was found that 𝑥2=67.247 (df=28, p<.001), GFI=.953, AGFI=.911, TLI=0.936, CFI=0.965 and RMSEA=.074. Emotional exhaustion was found to have a direct effect on job demand (β=.26) and an indirect effect on stress response (β=.31). The total effect was β=.57. There was a positive complete indirect effect of β=.52 between emotional intelligence and emotional exhaustion. The total effect was not significant, respectively. Conclusion: Since job demands of school nurses affect emotional exhaustion, it is necessary to reconstruct their jobs and operations to alleviate their job demands.

  • Fundamental studies at the CSIRO division of Wool technology and ICI on the diffusion of dyes into wool〔1,2〕have let to development of a new approach to wool dyeing. In this method, the cell membrane complex of wool is modified before dyeing by treatment under mildly alkaline conditions with a special chemicals. Wool pretreated with ethoxylated quaternary ammonium salt has an increased rate of dyebath exhaustion and dye penetration early in the dyeing cycle. This enables the treated material to be dyed below the boil for a similar time to the conventional cycle. This technique can be used on untreated and shrinkresist-treated wool and wool/nylon blends. In addition to good macro-levelness and excellent coverage of tippiness, the low temperature dyeing process give higher exhaustion levels of dyestuffs and insect-resist agent and hence cleaner effluent liquors, compared with conventional dyeing process. Low Temperature Dyeing process cause significantly less fiber damage than conventional way. The reduction in damage is reflected in improved processing performance of the dyed wool.

  • Purpose - The present study examines the effect of service employees' experienced customer incivility through their emotional exhaustion. We identified service employees' emotion regulation ability as a boundary condition (i.e., moderating variable) that decreased the positive relationship between service employees' experienced customer incivility and their emotional exhaustion. Furthermore, we also investigated the negative relationship between service employees' experienced customer incivility and their service performance via emotional exhaustion. Research design, data, and methodology - Drawing on AET (affective event theory) and COR (conservation of resources) theory, we developed three research hypotheses (i.e., mediation, moderation, and moderated mediation). Online panel survey data from 552 frontline employees at several service organizations (e.g., department stores, retail stores, hotels, restaurants, airlines, banking, insurance company, and etc) in South Korea were examined. To assess two types of validity (i.e., convergent and discriminant validity) and reliability of measurement model, we employed the CFA (confirmatory factor analysis) using M-plus 8.2 software. Internal consistency also was tested by Cronbach' α. In addition, we employed the SPSS PROCESS MACRO 2.16, which was recommended by Hayes (2013, 2015), to estimate mediation, moderation, and moderated mediation effects. Results - As predicted, the negative relationship between service employees' experienced customer incivility and their service performance was mediated by emotional exhaustion. Furthermore, service employees' emotion regulation ability also played a significant moderating role of the relationship between service employees' experienced customer incivility and emotional exhaustion, such that this relationship was less pronounced when service employees had a high level of their emotion regulation ability than when thir emotion regulation ability was low. Service employees' emotion regulation ability further moderated this mediation effect of service employees' experienced customer incivility on service performance through emotional exhaustion. These findings have theoretical implications for employees' experienced customer incivility and emotion regulation ability research and provide managerial implications for practitioners. Conclusions - This study empirically elaborated the previous model of service employees' experienced customer incivility and personal resource (e.g., emotion regulation ability) literature by presenting the findings that service employees' experienced customer incivility influences their service performance via emotional exhaustion and that emotion regulation ability effectively reduces this negative effect.
