  • This study was conducted to reconstitute a family life education program for caregivers and to analyze the system of implementation. Based largely on a pre-existing program for caregiving families, I developed a new educational program. Personal time management and personal needs management were added in the content of the program order to help enhance self-esteem and internal control. The reconstituted educational program, which consists of 6 sessions, was implemented on a small group of caregivers in Jeollabukdo Province who support their elderly parents. The effectiveness of the program was evaluated by a pre-test, a post-test, a follow-up test and open-questionnaire reports. The results from the post-test suggest that the program has been effective in improving the knowledge on aging process, internal control and self-esteem. But the follow-up test results show the program has been effective only in improving the knowledge on aging process. According to the open-questionnaire reports, the program seems to have been effective in improving interpersonal relationships and changing attitudes toward their elderly parents.

  • In this paper, the pole placement controller based on the Robust Internal-loop Compensator (RIC) structure, which has inherent structural equivalence to disturbance observer, is proposed to control a linear positioning system. This controller has the advantage to easily select controller gains by using pole placement without loss of that of original RIC structure. The principal is to construct the pole placement controller for a nominal internal model instead of unknown real plant. Using linear motion experiment showed the effectiveness of the proposed controller.

  • Purpose : The purpose of this study was to identify the effect of clinical nurse's locus of control of personality on job stress and job satisfaction and organizational commitment out of organizational effectiveness. Methods : The subjects were 463 staff nurses, who were employed in four university hospitals located in Seoul, Pusan and Kyungki-do. Data was collected from October 4th to October 14th in 2000 by a self-report questionnaire. Data was analyzed by the SAS for the general characteristics of the subjects, descriptive statistics, test for reliability and correlations. The effect of variables were tested using the Lisrel 8.12(a) program. Results : With the findings from this study, the internal-external locus of control affects job stress directly. Also it affects job satisfaction directly and via job stress indirectly. But it affects organizational commitment only via job stress and job satisfaction indirectly. Direct effect of locus of control to organizational commitment is not significant. Job stress affects job satisfaction and organizational commitment out of organizational effectiveness directly. Finally, job satisfaction was direct predictor of organizational commitment. Conclusion : Therefore, nursing managers ought to develop social learning programs to change the perception of individual personality and job stress management programs in order to improve organizational effectiveness.

  • In this paper, we proposed a novel control method which uses the internal impedance angles as a control parameter to drive traveling wave type ultrasonic motor. An impedance characteristic of the ultrasonic motor is obtained by analysis of the equivalent circuits including the external inductor used to generate the coupled resonance. The phase angle of internal impedance to achieve optimal control performance is derived. For the tracking of impedance angle, an information of phase difference is obtained from the applied voltage and current. The high speed phase difference detector is designed to monitor the phases of ultrasonic motor. The effectiveness of the proposed control scheme is clarified by experiments.

  • A 5-bar structure with redundant actuators is proposed as a finger mechanism. It is shown that one additional redundant actuator greatly enhances the load handling capacity of the system. The actuator location should be carefully decided to maximize the performance enhancement. Furthermore, we develop stiffness and frequency control algorithms based on the internal loading created by redundant actuation. The effectiveness of these algorithms have been demonstrated by simulations.

  • Objectives: The purpose of this study was to investigate the effectiveness and safety of ginseng seed oil in healthy subjects who have mild liver dysfunction. Methods: A randomized, double blinded, placebo-controlled trial was conducted. A total of 167 subjects visited Semyung University Hospital from July 1st, 2016 to June 10th 2017. Except for the 103 excluded subjects, 64 subjects were randomized into one of the two groups: an treatment group(n=33) and control group(n=31). Subjects were randomly given either ginseng oil seed capsules or indistinguishable placebo capsules(2 capsules per dose, twice per day). Laboratory tests(aspartate aminotransferase, alanine aminotransferase, gamma glutamyl transpeptidase, triglyceride, total cholesterol, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol) were performed to evaluate the effectiveness after 6, 12 weeks of treatment. Vital sign, laboratory test were performed to assess safety at every visit. Results: There were no significant differences in efficacy between treatment group and control group. There were some adverse events with no significant difference in symptoms and frequency between treatment group and control group. Conclusions: Although the efficacy of ginseng seed oil was not proved, ginseng seed oil did not worsen liver function and proved its safety. More study of ginseng seed oil and clinical trials are necessary to increase the usefulness of above-ground parts of ginseng.

  • Good Corporate Governance (GCG) has been implemented by companies, especially companies that have gone public. However, many local companies still have not applied the principles of GCG. This study examines the implementation of the CG concept which is not fully implemented in family businesses in Indonesia. Besides, this research also aims to find out the role of the Internal Audit function in enhancing GCG practices. This research is a qualitative study that uses in-depth interviews, observation, and data triangulation, to gather evidence from exploratory case studies conducted in three family business firms. The results of this study found that CG is essential for the successful run of family businesses. After analyzing the data, we developed a new theory called Islamic Integrity Governance. The Internal Auditor plays a key role in improving GCG and a vibrant and agile internal audit function can be an indispensable resource supporting sound corporate governance. The internal auditor provides objective assurance and insight on the effectiveness and efficiency of risk management, internal control, and governance processes. Therefore, the Internal Auditor is an important pillar for effective and efficient GCG implementation. This theory concludes several concepts such as THTCL (Trustworthy, Honest, Transparent, Creative, Loyal). Internal auditors are needed because the concept of control is useful for improving GCG in business.

  • Relatively little studies have investigated employee recovery from internal service failure, especially from the employees' perspective. When handling customer complaints, employees must not only deal with legitimate customer demands after a service failure, such as providing an apology, rectifying the problem, and offering compensation, but they must also manage illegitimate dysfunctional customers, who may yell, threaten, and even physically harm the employee. These negative experiences can have strong effects, and employees can exhibit higher levels of stress such as burnout and emotional labor, which have been linked to dissatisfaction, tension and anxiety, reduced performance and effectiveness, and a greater propensity to leave the firm, ultimately leading to negative financial consequences for the firm. These conditions result in internal service failure and create the need to recover employees-in other words, internal service recovery. However, little research has examined this issue so far. The purpose of the current study, therefore, is to investigate the relationship between internal service recovery and employee outcomes. A pre-test, post-test between-subjects experimental design was developed. Participants were 166 part-time students who were working full-time. The average age of the participants was 36.74 years, and 57.50% of them were female. The average length of employment was 13 years. Participants were randomly assigned to one of four groups of approximately equal size. Three of the groups were subjected to an experimental situation involving an internal service failure, while one group was not exposed to failure, thereby acting as a control group. This study contributes to the service marketing literature in several ways. First, the study extends service failure and/or recovery research by examining recovery in an employee context. Second, this study attempts to measure internal service recovery and to empirically demonstrate its relationship to employee outcomes. Third, this investigation emphasizes the managerial importance of internal service recovery. For example, understanding the nature of the relationships between internal service recovery and its consequences can improve the effectiveness and efficiency of managers' resource allocation decisions.

  • The paper presents a method for controlling induction motors using a nonlinear internal model control (IMC) approach. The process model and the inverse model are developed in the rotor flux coordinate. The main advantage of the proposed method is that it easily specifies the performance (steady state error, transient response, etc.) and the robustness of the controller by means of the IMC filters. Simulation results illustrate the effectiveness of the proposed method. Results on a real time system show that the control system has good performance and robustness against changes in motor parameters (rotor and stator resistances, rotor and stator inductances, rotor inertia).
