The purpose of this paper is to develop a training program for overseas Korean language teachers focus on preservice teacher. This thesis based on the 2017 Korean Language (prospective) Teacher Overseas Dispatch and Practical Training Assistance Project (Almaty, Kazakhstan region). The present task established prospective teachers, career teachers, and local teachers as the targets of each assignment. We focused on developing a program that could match each of these characteristics. For prospective teachers, the program was designed and conducted with the goal of "improving real expertise through practical training," whereas for career teachers the program was developed with the goal of "improving leadership" and "retraining teachers" by focusing on their abilities as middle managers to build and maintain foreign and domestic networks. For local teachers, the goal was to provide "retraining as Korean language teacher certification". The limitations of those unable to attend domestic meetings were alleviated through training, workshops, and meetings, and a program was developed for real education practical training. For prospective teachers and career teachers in particular, the program was designed to center on a system of collaboration in which classes based on international Project Based Learning(iPBL) were conducted, and groups prepared practical training and practice modules.

Recently our government operates earned value management system (EVMS) for improving work management system of the construction projects over specific scale. The EVMS is based on the integrated management between construction cost and schedule, the existing systems, however, are focused on the cost management by using wort quantity. This study suggests a work management mode1 to integrate construction cost with activity information. The model introduces a work task concept as a tool that can connect construction cost to activity information. The suggested model in this study is verified by using actual data for the applicability to practical construction projects.

With the commercial availability of very high resolution satellite imagery, the concealment of national confidential targets such as military facilities became one of the most bothering task to the image distributors. This task has been carried out by handwork masking of the target objects. Therefore, the quality of the concealment was fully depends on the ability and skill of a worker. In this study, a spectral clustering based technique for the seamless concealment of confidential targets in high resolution imagery was developed. The applicability test shows that the proposed technique can be used as a practical procedure for those who need to hide some information in image before public distribution

Purpose - This paper discusses the heterogeneous fixed fleet vehicle routing problem with pick-up and delivery (HFFVRPPD), for vehicles with different capacities, fixed costs, and travel costs. Research Design, data, methodology - This paper made nine assumptions for establishing a mathematical model to describe HFFVRPPD. It established a practical mathematical model, and because of the non-deterministic polynomial-time hard (NP-hard), improved the traditional simulated annealing algorithm and tested a new algorithm using a certain scale model. Result - We calculated the minimum cost of the heterogeneous fixed fleet vehicle routing problem (HFFVRP) with a single task and, on comparing the results with the actual HFFVRP for the single task alone, observed that the total cost of HFFVRPPD reduced significantly by 46.7%. The results showed that the new algorithm provides better solutions and stability. Conclusions - This paper, by comparing the HFFVRP and HFFVRPPD results, highlights certain advantages of using HFFVRPPD in physical distribution enterprises, such as saving distribution vehicles, reducing logistics cost, and raising economic benefits.

Purpose: The study was done to verify the effect size of the variables related to the emotional labor of nurses. Methods: A total of 47 article on variables related to the emotional labor of nurses and published from 2006 to 2014 were used for the meta-analysis. Results: Variables with the largest effect size related to emotional labor were identified as the variables of work task, organization and individual characteristics in descending order of effect size. The sub-factors with the greatest effect size in the work task variable were exhaustion and work commitment, while for organization variables, intention to change jobs had the largest effect size. For individual characteristics, physical symptoms had the largest effect size. Conclusion: The results of this study are meaningful as the first study to integrate research results on variables related to the emotional labor of Korean nurses, providing practical data for the management of emotional labor.

In recent years there has been much emphasis on the need for service firms to develop an organizational culture which facilitates the successful implementation of marketing activities. This study examines the relationship among marketing culture, service quality, customer satisfaction, and customer loyalty in fast food service firms. The results of empirical analysis can be summarized by the following: First, marketing culture(employee service quality, interpersonal relationships, selling task, organization, internal communications, innovativeness) had a significant direct effect on service quality. Second, marketing culture(employee service quality, selling task, internal communications) had a significant direct effect on customer satisfaction. It had also a positive, significant indirect effect on customer satisfaction through service quality. Third, service quality had a significant indirect effect on customer loyalty through customer satisfaction. Therefore, the results of the study provide the practical implication for establishment of service firms' marketing strategies, related to marketing culture.

In this paper we propose a path planning method for an autonomous mobile robot based on genetic algorithms(GAs). There have been a number of methods proposed for the path planning of a mobile robot. However, few algorithms have been developed for an on-line path planning of a mobile robot with the uncertain information of a task environment. Therefore, we propose a path planning algorithms based on GAs that has ability of creating path planning without the perfect information of a task environment and an ability of planning the efficient path by on-line process. Then we show a possibility of the practical use with the results of simulations and experiments.

Researches about scheduling distributed real-time systems have some weak points, not scheduling both sporadic and periodic tasks and messages or being unable to guaranteeing the end-to-end constraints due to omitting precedence relations between sporadic tasks. This paper describes the application model of sporadic tasks with precedence constraints in a distributed real-time system. It is shown that existing scheduling methods such as Rate Monotonic scheduling are not proper to be applied to the system having sporadic tasks with precedence constraints. So this paper proposes an end-to-end laxity-based priority assignment algorithm which considers the practical laxity of a task and allocates a proper priority to a task.

In this paper, a practical method to generate task strategies applicable to chamferless and high-precision assembly, is proposed. The difficulties in devising reliable assembly strategies result from various forms of uncertainty such as imperfect knowledge on the parts being assembled and functional limitations of the assembly devices. In approach to cope with these problems, the robot is provided with the capability of learning the corrective motion in response to the force signal trrough iterative task execution. The strategy is realized by adopting a learning algorithm and represented in a binary tree type database. To verify the effectiveness of the proposed algorithm, a series of simulations and experiments are carried out under assimilated real production environments. The results show that the sensory signal-to-robot action mapping can be acquired effectively and, consequently, the chamferless assembly can be performed successfully.
