A discrete event systems (DES) is a physical system that is discrete in time and state space, asynchronous (event rather than clock-driven), and in some sense generative(or nondeterministic). This paper presents the design of fifteen modular supervisors to control an experimental CIM testbed. These supervisors are nonblocking, controllable and nonconflicting. After verification of the supervisors by simulation, the supervisors for AGV system have been implemented to demonstrate their efficacy.

The present study interviewed Eight novice supervisors (i.e., counselling psychologists with fewer than 5 years of experience) to investigate the need for formal supervision training. A consensual qualitative research method was used to analyze data, and the result found four main domains, 12 sub-domains, and 33 categories. The results also indicated that novice supervisors believe their own supervisors and expert supervisors have a great understanding of individual counselling cases, and that the role of a supervisor is to help supervisees' ability to understand each case better. Novice supervisors generally take their own supervisors as their role models, although most of them did not receive formal training from their own supervisors. Novice supervisors seek advice on supervision from their colleagues or their own supervisors but still find supervising difficult. They also believe there is a great need for clearly set guidelines or a manual on providing effective supervision.

Supervisory control theory, which was first proposed by Ramadge and Wonahm, is a well-suited control theory for the control of complex systems such as semiconductor manufacturing systems, automobile manufacturing systems, and chemical processes because these are better modeled by discrete event models than by differential or difference equation models at higher levels of abstraction. Moreover, decentralized supervisory control is an efficient method for large complex systems according to the divide-and-conquer principle. Decentralized supervisors cannot observe the events those of which occur only within the other supervisors. Therefore decentralized supervisors can be designed according to supervisory control theory under partial observation. This paper presents a solution and a design procedure of supervisory control problem (SCP) for the case of decentralized control and SCP under partial observation (SCPPO). We apply the proposed design procedure to an experimental CIM Testbed. And we compare and analyze the designed decentralized supervisors and partially observed supervisors.

The purpose of this study was to examine the mediating effects of role ambiguity on the relationship between self-efficacy and job satisfaction of visiting supervisors for multicultural families. The subjects were 243 visiting supervisors for multicultural families. The data were analyzed with SPSS Win 15.0 using Cronbach's ${\alpha}$, hierarchical multiple regression and path analysis. The findings showed that both self-efficacy and role ambiguity exerted a significant effect on the job satisfaction of visiting supervisors for multicultural families. Further, it is important to note that the effect of self-efficacy on job satisfaction was mediated by role ambiguity. The study discussed implications in terms of job satisfaction of visiting supervisors for multicultural families.

The main purpose of this study is to present the strategies for strengthening the leadership of field supervisors to effectively prevent construction accidents. To this end, first, this research study reviewed the meanings, functions, types and characteristics of the leadership of field supervisors in safety management activities on construction sites through the literature review. Second, the researcher investigated the types of supervisors' leadership and the level of field safety management activities through questionnaires. Third, the types of supervisors' leadership are categorized by that level. Fourth, the leadership type of field supervisors is suggested to effectively prevent construction accidents. Finally, the strategies to promote supervisors' leadership are developed.

The purpose of this study was to understand the vivid realities of important technical and relational aspects of visual art that were emphasised during training by art therapy supervisors and educators. Max van Manen's hermeneutic phenomenological methodology was incorporated into the study. Summarising their main experiences, art therapy supervisors enabled experiences of reproducibility and immediacy in their supervision, and allowed visual art to be used as a tool to foster inner contact with their supervisees. To enable this experience, art therapy supervisors provided a creative foundation and a receptive environment that promoted creativity for supervisees to use and experience art beyond the role of passive viewers. The results of this research clarified how the participating supervisors interpreted the value of art therapy as a method to nurture the professional growth of trainees. Their contributions suggest experiences and methods that may effectuate future advancements in the field of art therapy supervision.

The purpose of this study was to investigate the influence of teachers' covert narcissism and supervisors' servant leadership on teachers' organizational cynicism. The subjects were 279 teachers employed in childcare centers in K Province. Data was collected by questionnaires, which required self-report by teachers. The collected data were analyzed by mean, standard deviation, Pearson's correlation, hierarchial regression, by using SPSS Win 19.0. The results of our study was as follows. First, main effects of teachers' covert narcissism and supervisors' servant leadership on teachers' organizational cynicism was observed. teachers' covert narcissism was positively associated with teachers' organizational cynicism. and supervisors' servant leadership was negatively associated with teachers' organizational cynicism. Second, supervisors' servant leadership was a better predictor of teachers' organizational cynicism than teachers' covert narcissism. Finally, interaction effects of teachers' covert narcissism and supervisors' servant leadership on teachers' organizational cynicism was not observed.

This study examined the difference in perception of supervision between supervisors and supervisees of community welfare centers. The survey subjects were 100 social workers working at social welfare centers in Seoul, Busan, and Incheon. The survey subjects were 62% women and 38% men in their 30s. Approximately 98% of supervisors and 88% of supervisees had a college degree or higher. Regarding the total working period of social welfare institutions, 82% of supervisors and 12% of supervisees had five years or more experience. Regarding the perception of the overall supervision between the supervisors and supervisees, the supervisors and supervisees reported a score of 3.79 and 3.46, respectively. In the perception of supervision according to function, in the case of administrative supervision recognition, the supervisors and supervisees reported a score of 3.78 and 3.43, respectively, and in the educational supervision recognition, the supervisors and supervisees reported a score of 3.65 and 3.29, respectively. Regarding supportive supervision perception, the supervisors and supervisees reported a score of 3.94 and 3.67, respectively. As shown in the above results, the difference in the perception of supervisor and supervisee's supervision by function shows that the supervisor's supervision by all functions is higher than that of the supervisee. As a result, such supervisions are relatively low among supervisees who are provided with supervisions than supervisions that are perceived as being provided by supervisors.

The purpose of this study was to investigate the perception about AI assistants and the differences between two groups, workers(secretaries) and supervisors(bosses), using the Q-methodology which has an advantage in understanding the types of subjective perceptions. Through literature reviews and interviews, 34 Q-samples were extracted, and then Q-sorting was conducted by P-samples(20 workers and 15 supervisors). As a result of Q-sorting, the types and characteristics of AI assistants perceived by each P-sample were explained. The perception of the workers divided into five distinct types, and the perception of the supervisors was divided into three distinct types. The most crucial factors in distinguishing between workers and supervisors' perceptions depend on whether they are capable of performing certain tasks and whether they can replace existing secretarial jobs. This study, as the primary research on AI assistants, can help to redefine the work that can be replaced by AI and the work that only people can do, and thus to establish education, recruitment, and training plans.
