Objectives The purpose of the present study was to examine the relationship between the chronotype and the burnout, so we investigated the mediating effects of the mediators such as perceived stress, stress response, and depression. Methods Employees working at Incheon Customs conducted a mental health self-examination through the internet. Among them, 174 people who agreed to the mental health survey participated in the study. Participants completed questionnaires including Composite Scale of Morningness (CSM), Center for Epidemiological Studies-Depression Scale (CES-D), Perceived Stress Scale (PSS), Stress Response Inventory (SRI), Maslach Burnout Inventory-General Survey (MBI-GS). Results Our results showed a higher degree of CES-D, SRI, exhaustion, and cynicism in evening and intermediate type compared to morning type, and a higher degree of professional efficacy in morning type compared to intermediate type. CSM was shown to have a direct effect on exhaustion and indirect effect through CES-D and SRI. CSM also had a direct effect on professional efficacy and had an indirect effect through the CES-D. However, CSM was found to have only indirect effects through the SRI for Cynicism. Conclusions In this study, individuals with evening type tend to experience a high degree of burnout (exhaustion, cynicism and professional efficacy) through the mediation effect of depression and stress response. Further study is necessary to reveal the effect of management of the depression and stress response in the employee with evening type.

This study examines the influence of parental social support and resiliency of efficacy on stress, depression and stress management behavior. A total of 799 participants (male=386, female=413), consisting of 184 elementary school, 354 middle school, 274 university students completed a questionnaire that included Rhode Island Stress Scale (Horiuchi, Tsuda, Tanaka, Yajima & Tsuda, in press), Stress Management Behavior Scale (Evers, Prochaska, Johnson, Mauriello, Padula & Prochaska, 2006), Becks' Depression Inventory (BDI-II, Beck, Steer & Brown, 1996; CES-D, Radloff, 1977), Resiliency of Efficacy (Bandura, 1995), and Parental Social Support (Kim & Park, 1999). The results of path analysis are as follows. First, resiliency of Efficacy had a direct and negative effect on stress and depression and direct positive effect on stress management. Second, stress management behavior did not have any influence on stress. Third, parental social support had a direct and positive effect on resiliency of efficacy. This pattern of results were found for elementary school, middle school and university students. When depression was measured by CES-D Scale (Center for Epidemiological Study of Depression) parental social support and resiliency of efficacy had a different parental of influence on stress, depression and stress management behavior, pointing out the importance of conducting comparative analysis of various measures of depression.

Zellner, Kmenta, Dreze (1966) and later Hedges (1969) showed that consistent estimates of the parameters of Cobb-Douglas or CES production functions can be obtained by the single equation estimation methods if the models incorporate the assumption that firms maximize the mathematical expectation of profits. This note demonstrates that the results of the above-cited works can be extended to a class of VES production function models.

This paper discribes the differen-ces between making handset sample and handset massproductions. To save time during mass production, Calibrat-ion should be automated and SW do-wnloading also be automated and Par-allely done. All this processes are des-cribed here. Especially Calibration are more detaily explained in this paper.
