This paper investigates the relationship between the two problems, supervisor reduction and observation function (projection) design, which arise in supervisory control of DEDS. It is shown through an example that a reduced supervisor of minimal size does not necessarily result in a maximal projection when a projection design method which uses the transition structure of a supervisor is applied. Also, if an L-realizable projection P is available and if a supervisor has a special structural feature, a cover C for supervisor reduction can be easily obtained. By investigating the control-compatibility of states of the reduced supervisor based on C, we can also check maximality of P in a simple manner.

건설프로젝트에 있어서 공사감독은 공정관리, 품질관리 안전관리, 원가관리에 중요한 영향을 미친다. 그러므로 건설공사의 초기단계에서부터 감독의 지속적인 관리활동이 필요하다. 그러나 국내 공공 건설공사에서 감독의 업무량과 비용에 대한 평가가 미비한 실정이다. 또한 공사 감독이 초기단계에서부터 지속적인 관리활동이 가능한지에 대해서도 회의적인 시각이 상존하고 있다. 본 연구에서는 우리나라 공공발주처에서 시행하는 공사의 감독 업무와 외국에서의 공사감독의 관리활동을 비교$\cdot$분석하였다. 또한 국내 건설공사에서 감독에 소요되는 비용과 감독을 대체한 감리원을 활용하였을 때의 비용을 평가하였다. 이를 통하여 향후 감독업무의 개선이 가능하고 비용적 측면에서 인건비 등 공사 간접비의 절감을 기할 수 있겠다.

The present research aims to examine whether learning from the supervisor influences readiness for change with the mediating impact of planfulness. Drawing upon the theory of planned behavior, it is hypothesized that learning from the supervisor positively impacts planfulness ability in individuals, which in turn enhances the readiness for change. Through using convenience sampling, the sample of 451 was collected from employees working full-time in the manufacturing and I.T. service organizations in India. Structural equation modeling and regression analysis indicate that learning from the supervisor is positively associated with readiness for change and planfulness. Additionally, planfulness fully mediated the relationship between learning from the supervisor and readiness to change. The findings of the present research highlight that continuous support and learning from the supervisor enhances the planfulness ability of the individual and consequently enhances individual readiness for change. The current research is pioneering in testing the hypothetical model associating learning from the supervisor, planfulness, and readiness for change.

Background: Workers exposed to hazards without adequate protections are at greater risk of injury and illness. Supervisor activities have also been associated with injury risk. We examined the interplay between supervisor safety support and occupational health and safety (OHS) vulnerability on workplace injury and illness. Methods: A survey was administered to 2,390 workers employed for more than 15 hrs/week in workplaces with at least five employees who had a direct supervisor. We examined the combined effects of hazard exposure with inadequate protection (OHS vulnerability) and supervisor support on workplace injury and illness, using additive interactions in log-binomial regression models. Results: OHS vulnerability and lack of supervisor support independently increased the likelihood of physical injuries at work. Crude and adjusted models showed that the risk of physical injury was at least 3.5 times higher among those experiencing both OHS vulnerability and a lack of supervisor support than individuals without OHS vulnerability and with a supportive direct supervisor. Workers who experienced vulnerability were at less risk if they had a supervisor who was supportive. Conclusion: In workplaces where workers experience one or more types of OHS vulnerability, having a supportive supervisor may play an important role in reducing the risk of injury and protecting workers.

In this paper, we present a procedure to design the robust optimal supervisor which has the minimal cost in the sense of average for a given multiple-modelled discrete event system DES. In order to design the robust optimal supervisor, we extend the optimal supervisor design algorithm for a deterministic DES to the case of multiple-modelled DESs. In addition, using the proposed algorithm with modified costs of events and penalities of states, we can show whether a robust supervisor for a given multiple-modelled DES exists and design the minimally restricted robust supervisor.

The purpose of this study was to investigate the relationship between depression, colleagues/ supervisor's emotional support and burnout experienced by teachers in kindergartens and childcare centers. The subjects were 195 teachers who worked in kindergartens or childcare centers in Daegu and Gyeongbuk Province. Questionnaires, which required self-report by teachers, were used to investigate depression, colleagues/supervisor's emotional support and burnout. The data collected were analyzed by means of paired t-test, Pearson's correlation, simple regression, hierarchial regression, using SPSS Win 15.0. The results are as follows. (1) The emotional support from colleagues was significantly higher than from that provided by the supervisor. Moreover, teachers' depression levels were positively associated with burnout. (2) Colleagues' emotional support operated as major determining factor with the effect that burnout decreased as colleagues' emotional support levels increased. There were observable interactional effects between depression and the emotional support provided by colleagues' to colleagues experiencing burnout. (3) The supervisor's emotional support operated as a major factor with the effect that burnout decreased with a rise in the levels of a supervisor's emotional support. No interactional effects were observed between depression and supervisor's emotional to colleagues dealing with burnout.

Purpose - This study analyzes the intertemporal patterns in personnel decisions made between a supervisor and a subordinate to understand potential supervisor bias in the decisions. A correlation between the current and the most recent personnel decisions made for a subordinate by a current supervisor captures certain relationship-embedded and time-invariant factors in effect. The characteristics speak to the nature of a supervisor bias arising from a relationship, or favoritism. Design/methodology/approach - This study manually collects the executive profile data from annual reports of key Samsung Group affiliates and compile a longitudinal sample of 3,675 executive-years. It mainly explores the logistic regression analysis. Findings - The study finds that a supervisor' previous promotion award to a subordinate does not improve but decreases the likelihood of promotions in ensuing years, suggesting the containment of favoritism; and that the time since the last promotion award to a subordinate by the current supervisor increases the likelihood of both promotions and dismissals of the subordinate. Research implications or Originality - The findings are generally consistent with the theory suggesting that incentive schemes that align interests between an individual and an organization will contain the form of a supervisor bias.

Knowledge creation has become one of core assets for companies' survival and success, companies are putting their effort to find the way to stimulate sharing knowledge among their workers. In this vein, the purpose of this study was to examine the effect of supervisor support and co-worker support on knowledge sharing and the mediating effects of work engagement. 328 employees from varity of organizations located in Korea particiapted for questionnaire survey. Structural equation modeling was used to analyze the data. The result has shown that the static correlation exists between supervisor support, co-worker support and work engagement. Co-worker support had positive influences on knowledge sharing intention. However, supervisor support did not have any influence on knowledge sharing intention. There was a mediate effect of work engagement between both of supervisor and co-worker support and knowledge sharing intention. The study implies that co-worker support is important in order to improve organizational learning and work engagement as a strategy to enhance organizational performance.
