In this paper, a high precision track following control algorithm is proposed for micro electrostatic actuator considering of the application for hard disk drive. The micro electrostatic actuator proposed has nonlinear voltage-displacement characteristic in a working range of 0.8.mu.m and has uni-directional movement. Mid range reference and open-loop bias are proposed for the revision of negative position error, and inverse model for linearization.

An X-ray Free Electron laser facility (PAL-XFEL) has been built in Pohang Accelerator Laboratory to provide X-ray FEL radiations for photon users. The machine consists of a 10 GeV normalconducting S-band linear accelerator and two undulator beamlines. The hard and soft X-ray beamlines will provide FEL radiations with wavelengths of 0.6 to 0.1 nm and 4.5 to 1 nm, respectively. Beam commissioning of PAL-XFEL is ongoing and user service will start in 2017. In this report, the PAL-XFEL layout and the working principle are discussed.

This paper condisers a problem of determining arc capacities for a communication network with fixed-charged linear arc-cost functions, which is known to be NP-hard. For the problem, an efficient heuristic solution procedure is derived. The procedure is further shown working well for designing arc capacities of a network in a situation where the network needs to be extended by connecting its nodes to some new nodes or where the network needs to be extended by expanding its arc capacities.

In forest work, working conditions are very hard to improve. The good posture is believed to bring about direct improvements such as accident prevention. Therefore, this research carried on analysis of working posture in forest work (construct in stepping-stone) using OWAS analysis system. According to the analytical results provided by OWAS, the ratio of category III (Work posture has a distinctly harmful effect on the musculoskeletal system) has shawn that worker 2 was 32.2%, worker 1 was 25.2% and worker 3 was 15.5%. Furthermore, the ratio of category IV (Work posture with an extremely harmful effect on the musculoskeletal system) has shown that worker 2 was 9.8%, worker 3 was 1.4% and worker 1 was 1.2%. According to the OWAS method, percentage of OWAS action categories III and IV in the worker 2 was higher than another workers.

Purpose - This study examined workplace bullying as a situational antecedent of workaholism and burnout as a consequence of workaholism and explored the mediating role of workaholism and the moderation effect of perceived organizational support. Research design, data, and methodology - This study collected data from 319 employees in South Korean companies through a survey method. Results - First, job-related bullying promotes a compulsive and excessive drive to work. However, person-related bullying was positively related to the tendency to work excessively hard. Second, only working excessively shows positive relationship with only exhaustion excepting cynicism. Third, although bullied employees may reserve their personal resources through workaholism in short time, it drives them to be workaholic, which leads them exhausted in turn. Finally, perceived organizational support decreases the effect of job-related bulling on both of working compulsively and working excessively. Conclusions - First, this study suggests workplace bullying as a situational antecedent and verify burnout as a consequence of workaholism. Second, it investigate the mediating role of workaholism and the moderation effect of perceived organizational support. Practically, When they find workaholic employees, they should investigate if workplace bullying exists through face-to-face talk. If necessary, they should decide personal transfer to the other department or work team.

본 연구는 영업성과의 중요한 원인변수로 밝혀진 바 있는 학습지향성, 성과지향성, 현명하게 일함, 적응판매 능력의 개념을 보다 구체화하기 위하여 성과가 높은 영업사원 5명과 성과가 저조한 6명의 영업사원들의 영업전반에 관한 활동을 심층적으로 조사한 후 그 차이를 분석하였다. 본 연구가 11명의 정보제공자의 면접기록을 종합하여 분석한 결과 영업성과가 우수한 사원들은 다음과 같은 고유한 특징을 갖고 있었다. 첫째, 성과가 우수한 사원들은 일에 대한 자세에서 영업을 일로 생각하지 않고 자신의 생활 일부로 간주하고 있었고 자신이 하는 일에 대한 자긍심을 갖고 있었다. 둘째, 성과가 우수한 영업사원들은 자신의 부족함을 영업전반에서 인식하고 있고, 그에 따라 교육에 보다 적극적으로 참여하고 있으며, 자사뿐만 아니라 경쟁사 제품에 대한 학습도 매우 성실하게 수행하고 있었다. 셋째, 성과가 우수한 사원들은 영업목표를 보다 고객 중심적으로 세우고 있었고, 그 목표도 보다 수치화되어 있었으며, 이를 달성하기 위한 방법도 구체적으로 세우고 있었다. 넷째, 성과가 우수한 사원들은 고객 중심적 사고를 보다 구체적으로 실행하고 있었고, 고객을 스타일이나 성격 등을 이용하여 구분한 후 유형별로 적절하게 상담하고 있었다. 마지막으로 성과가 우수한 영업사원은 모든 영업단계에서의 고객별 세심한 준비를 하고 있었고, 장기적인 관점에서의 관계형성 노력을 기울이고 있었다. 이러한 연구결과는 영업사원의 고객지향성과 적응판매능력이 객관적으로 평가되어야 하고, '현명하게 일함'과 '적응판매능력'은 구분되어 분석될 필요가 있음을 시사하고 있다.

In forest work, working conditions are very hard to improve. The proper distribution of work time and good posture is believed to bring about direct improvements such as accident prevention. On this, this study has analyzed forest workers' posture and their working hours in order to improve their working conditions in stone channel work. Authors has chosen several core elements of stone channel work to focus on, which include stone masonry, excavation of bed, moving stone, directing work, choosing stone, and breaking stone. The ratio of real working time over total working time was shown as 84.6%. As for the time ratio of each elemental work over the real working time, the stone masonry was 60.4%, the directing work was 15.1%, moving stone was 12.1%, choosing stone was 7.1%, breaking stone was 3.3%, and excavation of bed was 2.0%. According to the analytical results provided by OWAS, the ratio of category III (Work posture has a distinctly harmful effect on the musculoskeletal system) has shown that moving stone turned out 65.2%, choosing stone was 61.5%, stone masonry was 46.1%, breaking stone was 14.3%, excavation of bed was 12.5% and directing work was 6.8%. Furthermore, the ratio of category IV (Work posture with an extremely harmful effect on the musculoskeletal system) has shown that excavation of bed turned out 37.5%, breaking stone was 28.6%, stone masonry was 27.3%, choosing stone was 7.7%, moving stone was 6.1% and directing working was 4.5%. These results are expected to be utilized for the improvement with respect to both working methods in the stone channel work and the workers' working posture.

This study was conducted to compare the value of the working environment measurement with the expected exposure value drawn by using a program, thereby going to investigate whether it is available to the risk assessment of domestic workplace. We used the ECETOC TRA program which is one of the exposure predictive models. Four kinds of substances were measured in two workplace which was exposed to organic solvents and one kind of substance was measured in three workplace which was exposed to dusts and then an exposure assessment of chemical risk factors was conducted. The result value of the working environment measurement, solid substance exceeded standard in one site, and it was found that the other solid and liquid substances were within the standard. The value of the exposure assessment program showd the same result; it was higher than the value of the working environment measurement, suggesting that due to its nature, the exposure assessment program is run only on the worst situation. Therefore, it was found that when the exposure assesment program is used, variables should be substituted only after accurately assessing the workplace and it is a good idea to assess the risk beforehand with the exposure assessment program in the case of the workplace which employs no more than 5 people and where it is hard to assess the working environment.
