  • This study proposes an AC servo motor control program structure and its implementation method to efficiently integrate 13 types of additional compensation algorithms into the basic FOC (field-oriented control) algorithm program. Various compensation algorithms are necessary to enhance the stability and performance of machine tools by compensating for interference from disturbances and vibrations. Each compensation algorithm is implemented as a separate, independent function and called from a switch-case statement in the ISR (interrupt service routine) of the PWM (pulse-width modulation) device. The advantages of this approach include facilitating not only debugging and testing but also reducing the possibility of errors during the program development phase. Thus, it is easy to add and activate each specific compensation algorithm for the program update during the program operation phase. The implemented motor control program was experimented with a single-axis feed shaft testbed driven by a commercial AC servo motor control drive board and a 750 Watts SPMSM (surface-mounted permanent magnet synchronous motor), and the results verified its normal operation and performance improvement.

  • For the development of compensation machining program, ultra precision grinding used in ultra precision machine and corrective machining was studied. We explored a new rough grinding technique on optical material such as zerodur. The facility used is a polishing machine with a custom grinding module and a range of diamond resin bond wheel. Surface roughness and form accuracy are measured by surface measurement equipment(Form Talysurf series2). Our compensation machining program has complied with a target of producing surface roughness better than $0.05{\mu}m$ Ra and form accuracy of around $0.05{\mu}m$ Rt and has been unveiled as a work-hour model.

  • In this paper, we propose a new shape compensation scheme to make up for the difference in groove radius between the formed tools and the machined bearing raceways, which inherently takes place during machining the ball bearing raceways by the turning process using conventional formed tools. The associated conventional methods of the formed tool design and its modification such as a simple depth compensation method and a graphical compensation method are introduced and the latter, which has been known to be the better of the two, is experimentally investigated in detail to reveal its drawback. The algorithm is given and it is applied to develop a formed tool design program. The program developed by the presented approach is successfully applied to design the formed turning tool for the bearing raceways.

  • Purpose: This study aimed to investigate the effect of an intensive rehabilitation program on the pain, range of motion (ROM), muscle strength, function, quality of life (QoL), and depression of patients with traumatic rotator cuff injury caused by an industrial accident. Methods: Seventeen patients with traumatic rotator cuff injury caused by an industrial accident participated in this study. The 12-week treatment included 30 min of manual therapy and 30 min of exercise therapy twice a day, five times a week. The outcomes were measured for evaluating the pain, ROM, muscle strength, function, QoL, and depression before the commencement of the program and after 4, 8, and 12 weeks. Results: According to the time of applying the intensive rehabilitation program, the pain (p<0.01), ROM (p<0.01), muscle strength (p<0.01), function (p<0.01), and depression (p<0.05) significantly improved with time. However, QoL was not statistically significant. Conclusion: This study confirmed the excellent effect of an intensive rehabilitation program on the pain, ROM, muscle strength, function, and depression of patients with traumatic rotator cuff injury caused by an industrial accident. However, this study was limited by the absence of a control group. This pilot study highlights the need for more extensive research with a larger sample.

  • This study aims to investigate the determinants of turnover intention among company managers in Indonesia. Based on the literature, this research hypothesizes that job satisfaction is a mediator in the relationship between compensation, career and turnover intention of companies in Indonesia. Respondents as research samples are grouped into middle managers from two industries, namely, manufacturing and services. A total of 215 questionnaires were returned from middle managers. Data analysis used Structural Equation Model - Linear Structural Relationship (SEM LISREL). The research results prove that compensation and career have a positive effect on job satisfaction. Compensation, career, and job satisfaction have a negative impact on turnover intention. Compensation is known to be one of the motivating drivers of workers around the world. From this study it can be said that, if middle manager teachers are well compensated, they will be encouraged, persuaded and will have positive feelings toward their work, and this will result in staying put. It works also with career and job satisfaction. If both variables are considered carefully, intention to move tends to be low. These findings provide new insights into the field of international human resources in developing multinational companies and service businesses.

  • In order to meet the optical performance in the process of the micro lens manufacturing with plastics, it is important to embody accuracy in shape and surface roughness to the intended design. Since it is difficult to machine exactly the mold core of lens fit to the designed shape, in this paper, a simple program using MATLAB is developed for shape correction of the mold core after first machining it. This program evaluates correction parameters(aspheric coefficients and curvature) and generates aspheric NC data for compensating the core surface in prior machining process. The program provides the way to manufacture plastic injection molding lens with aspheric shape of high precision, and is expected to be effective for correction and to shorten the processing time.

  • This study analyzed what premium features significantly affect customer satisfaction and their recommendation, and what factors significantly affect product attributes. In the process, first, the loyalty program and the customer compensation program were studied to determine the impact of the customer satisfaction and recommendation. The study analyzed that quality and design of product properties had significant effects on all factors, but the brand was not significantly affected. Second, while superiority, differentiation and scarcity of luxury items are significant to customer satisfaction but superiority is only significant in relation to recommendation intention. Third, the preceding study shows that the customer compensation program has a significant impact on sales growth, but the study found that it was not for imported luxury car customers. Fourth, if the royalties program is low in awareness, it has been analyzed that the scarcity and customer satisfaction relationships among luxury goods have been adjusted. On the contrary, if there is a high level of awareness, it is analyzed that there is a control effect customer satisfaction and differentiation among luxury brands. In the conclusion, in order to satisfy customers at the import luxury car market, the differentiation of luxury goods by standard index must be strengthened and the brand must be strengthened among the attributes of the product. In addition, by raising awareness of the royalties program, the relationship between differentiation and customer satisfaction can be enhanced.
