This study aims to design and implement individual complete learning system based on IPI(Individually Prescribed Instruction) model. Most of current web based learning systems do not consider individual students' ability and just follow the sequence of instructing contents $\rightarrow$ providing problems $\rightarrow$ presenting the result of evaluating. However, this system focuses on individual ability prior to studying subjects. In individual complete learning system, it is acknowledged that a period and a pace to complete each task will differ from students to students, therefore until they complete the whole unit, they are not allowed to move onto the next unit. After completing each unit, there will be a process of evaluating students' performance. It is necessary to show the correct completion of 80% of the evaluation to move onto next step; for those who are evaluated as inadequate to move on, an individual supplementary instruction will be provided. Therefore, this study intends to supplement the deficit of prior learning and provide feedback dependent on individual's learning ability so that the goal of Individual Whole Complete Learning could be accomplished.

The purpose of this review was to investigate feasibility of intensive virtual reality training to improve upper extremity function with brain plasticity of individuals with stroke through the literature. The recovery of the paretic upper extremity depends on regularity and intensity of training as use-dependent plasticity. In resent, virtual reality program has been widely used in the occupational therapy field of augmented stroke rehabilitation. There is a growing body of evidence that virtual reality training of the paretic extremity induces brain plasticity associated with motor improvement. In terms of therapeutic feasibility to improve paretic upper extremity, recent research has explored several important factors of virtual reality training for recovery of upper extremity motor function. These factors include high repetition intensity, high motivation like type of game, enhanced multisensory feedback regarding performance, and interactive task-oriented training. Therefore, occupational therapy combined with intensive and repetitive virtual reality training will enhance recovery of upper extremity motor function after stroke.

There has been a growing need for interaction between human operator and a remote system to perform a complex task in an unpredictable environment and to operate an important work at a remote distance. The interaction becomes an important parameter in the teleautonomous operation because it permits the operator to control the system at remote distance. As the environmental uncertainties to be applied are getting increased, so is the difference between the plan of the operator and the execution of the system increased. Since the operator may be difficult to know the latest information from frequently changing environment due to time-varying delays, remote system may be hard to control in accordance with the operators command. Interactive Teleautonomous Control System (ITCS) is an approach based on interactions at these environments. The ITCS can be regarded as a control system using the transmitted a system's intnetion. The interactive teleautonomous control does not mean the interaction from operators point of view only considering feedback environmental information and forward simulation but an interaction between the operator and the system that transmits or receives intentions. The proposed ITCS is based on the intention communication that transmits their intentions to each other. The ITCS can correctly control the system in accordance with the operator's intention. Using the intention communication, a system intention is helpful to the operator. In the interactive teleautonomous control, the intention communication has to be provided by the interaction between the operator and the system.

The purpose of this study is to investigate the effect of the preceptorship on nursing performance and job satisfaction of the preceptor. This study was as a one group pretest-posttest study. The subjects were 33 nurses who was selected as preceptors in 1998. This study was carried out from 16 April 1998 to 25 May 1998. Nursing performance was measured on a 6-D scale developed by Schwirian (1978) and job satisfaction was measured by a tool developed by Slavitt et al.(1978) and interpreted by Yoon (1990). The collected data were analyzed by paired t-test with SPSSWIN. The results were summarized as follows: 1. After the preceptorship, nursing performance of the preceptor increased significantly compared to before the preceptorship. All of the score of subscales was increased. 2. After the preceptorship, job satisfaction of the preceptor was increased slightly compared with before the preceptorship, but it was not statistically significant. The scores of the subscales increased in job status, interaction, autonomy, and organization. However, the score of the task requirement was decreased. Through the results of this study, increase in nursing performance, but only a slight increase in job satisfaction can be observed(not statistically significant). It seems that the content of preceptor program, the principle of adult learning, scientific problem solving, communication, feedback, and direct teaching experience affect the individual nursing performance of the preceptor. The preceptorship was useful with personnel development in terms of organization. To fully carry out the role of educating the preceptee, it is important to motivate the preceptor and to induce job satisfaction of the preceptor.

Recent changes in educational paradigms that emphasize the performance or outcomes of education are redefining how learning objectives are being described as 'learning outcomes' in various academic disciplines. Medical education is not an exception to this trend. However, it has come to our attention that the key concepts and appropriate descriptions of learning outcomes have not been well understood among educators and that this lack of understanding has hindered our efforts to implement the practice in the field. This study aims to provide a direction to establish and describe learning outcomes by examining previous studies that have focused on setting learning objectives as well as learning outcomes. Setting and describing learning outcomes starts from reflection on the approach of behavioral learning objectives, which overemphasizes learner's acquired knowledge, skills, and attitude in each classroom rather than actual performance. On the other hand, the learning outcome approach focuses on what the learner is able to do as a result of a learning experience. This approach is more learner-friendly and encourages students to lead and be responsible for their learning process. Learning outcomes can best be described when the relevance of actual contexts and the hierarchy of learning objectives are considered. In addition, they should be in the form of context, task, performance, and level, as well as be planned with proper assessment and feedback procedures. When these conditions are met, the learning outcome approach is beneficial to students as it presents a curriculum that is more open to learners. Despite these advantages of the learning outcome approach, there is a possible concern that setting the learning outcomes and describing them can restrict evaluation to lower cognitive skills if the concept of learning outcome is narrowly interpreted or is set too low. To avoid such narrow applications, it is important for educators to understand the comprehensiveness of the learning outcome setting and to consider long-term outcomes embedded in an organizational vision rather than only short-term behavioral outcomes.

With the emergence of indirect procurement, it has become a global trend for companies to outsource their maintenance, repair, and operating (MRO) supplies to procurement service providers (PSPs). Due to the variety of MRO items, evaluation of numerous suppliers in various industries is a particularly complex task for PSPs. Due to this complexity, many PSPs still evaluate and select suppliers based on the sourcing managers' subjective knowledge. Through the case of adopting a supplier evaluation system, this research is to find the managerial issues organizations should consider when they transform sourcing managers' knowledge into the system. We interpret the issues based on the Technology-Organization-Environment (TOE) framework. This case conclusively shows the importance of positive feedback loop between the users and the information system for the performance improvement of the system.

Purpose: This study was conducted to provide basic data for human resources management of hospital foodservice employees by determining their job characteristics, job satisfaction, and organizational commitment according to recent hospital environment changes. Methods: Our survey was administered to 248 hospital foodservice employees in Busan area from September 1 to September 25, 2014. A total of 158 questionnaires were used for final analysis. Results: The mean score of job characteristics showed significantly difference by work experience (p<0.001), annual salary (p<0.01), and cooking certification (p<0.05). Job satisfaction had significantly difference by the age (p<0.05), annual salary (p<0.001), and turnover intention (p<0.001). Organizational commitment showed significantly (p<0.001) difference by age, work experience, and annual salary. There was positive correlation (p<0.001) between organizational commitment and job characteristics, job satisfaction. Organizational commitment had significantly positive correlation with skill variety (p<0.001), feedback (p<0.01), and task significance (p<0.001) of job characteristics, with work (p<0.001), pay (p<0.001), and co-workers (p<0.001) of job satisfaction. Job characteristics (${\beta}=0.249$, p<0.001) and job satisfaction (${\beta}=0.380$, p<0.001) had positive influences on the organizational commitment(p<0.001). In sub factors of job satisfaction, work (${\beta}=0.291$, p<0.001) and pay (${\beta}=0.252$, p<0.01) had positive influences on organizational commitment. Conclusion: To develop the organizational commitment, hospital managers need to reinforce responsibility and fulfillment by job enrichment and to consider increasing salaries to get a higher satisfaction from foodservice employees.

In this paper, a compliance robot control algorithm using a PID adaptive controller is proposed. The compliance robot is suitable for the tasks in contact with environment, such as assembly operation or surface processing. A hybrid robot control method can control force and position simultaneously and two independant feedback closed loops are formed in this method. Because the compliance robot is operated in contact with environment, it is very difficult to obtain linear model of dynamics for this robot. In order to overcome this difficulty, a PID adaptive controller independant of robot dynamics is applied to the compliance robot. The proposed control algorithm for the compliance robot was analyzed and conformed by simulating the surface processing task by a two-joint robot.

This paper presents various strategies for humanoid vehicle driving and egress tasks. For driving, a tele-operating system that controls a robot based on a human operator's commands is built. In addition, an autonomous assistant module is developed for the operator. Normal position control can result in severe damage to robots when they egress from vehicles. To prevent this problem, another approach that mixes various joint control techniques is adopted in this study. Additionally, a footplate is newly designed and attached to the vehicle floor for the ground landing phase of the egress task. The attached plate enables the robot to step down onto the ground in a safe manner. For stable locomotion, a balance controller is designed for the humanoid. For the design of the controller, the robot is modeled using an inverted pendulum that consists of a spring and a damper. Then, a state feedback controller (with pole placement and a state observer) is built based on the simplified model. Many approaches that are presented in this paper were successfully applied to a full-sized humanoid, DRC-HUBO+, in the DARPA Robotics Challenge Finals, which were held in the United States in 2015.
