Purpose: The purpose of this study was to describe the reported experiences of health management among twenty elderly workers living in urban areas. Methods: Corbin and Strauss's grounded theory approach was used to capture the meaning of health management. Theoretical sampling technique was used in the interviews. Using open coding, axial coding, and selective coding, data were collected and analyzed simultaneously. Results: The core category was 'pursuing health to take root in the workplace.' Four stages of the elderly workers' health management were identified as 'awareness of health changes', 'having the will to be healthy', 'utilization of health care resources', and 'reorganization of health habits.' However, when the elderly workers reported limited capacity to manage their health, then two new categories were described: 'awareness of health changes' and 'settlement with current health.' Conclusion: To the elderly workers the concept of working was equated with being healthy. Further, the participants reported having a future oriented view of health and sought health to extend their working lives. The specialized intervention of health management targeting elderly workers in the settlement stage of current health habits should be provided.

The objective of this study is to investigate the effect of HR practices such as (Recruitment, empowerment, working condition and compensation) on Job satisfaction in the prospects of Hotel Industry of Pakistan. The sample size for this study was 100 employees who were selected through convenience sampling techniques. This study was restricted to 10 Hotels of Peshawar. Hypotheses of the study were tested through correlation and regression analysis to inspect the employee's satisfaction. The findings investigates that there is significant relationship between HR practices and job satisfaction. Moreover Recruitment and selection, empowerment and working condition have positive effect on job satisfaction, while compensation has negative effect on job satisfaction, which indicates that most of employees are not satisfied from payment of employer. Empirical findings concluded that best HR practices have significant and positive effect on employees job satisfaction. Therefore, it is suggested for HR manager to understand and implement the HR practices correctly to take good work from their employees.

This paper is the forth paper of several companion papers which compare the method of Air-Fuel ratio determination. In the previous work, various AFR calculations were performed for various fuels and the results were compared with each other. The comparison, however, were limited to numerical value and estimation of each equation or method was insufficient. In this paper, the overall estimation of the methods was attempted. Also, the method of trouble shooting of instrumentation was presented. Through the estimation of methods, it is concluded that the Eltinge method contains inherently the most perfect thermal dissociation model as far as the exhaust composition is concerned; therefore, this might be regarded as the most general equation of AFR determination among the existing ones. The others might be considered as approximate form. In addition, the mal-distribution factor in Eltinge method is qualitatively equivalent to thermal dissociation chemical equilibrium constant K. Lastly, it is illustrated that all instrumentation error, including the sampling line leakage, can be easily detected through the analyzing the exhaust component on the Eltinge chart.

본 논문에서는 LCD 판넬 밝기의 균일성을 향상시키기 위하여 램프간의 저항 차이를 검출하는 회로를 사용한다. 기준 loop와 비교 loop의 feedback 전압을 나누어 검출된 저항의 차이는 PWM duty를 결정하는 제어 모드와 연결하여 램프 저항에 맞는 전압을 램프에 인가한다. 기준 loop의 feedback 전압은 모든 loop의 기준 전압이 되며, 하나의 IC에 램프의 수만큼 외부 기판을 연결하여 사용할 수 있다. 모든 비교 loop의 램프들은 기준 램프와 같은 밝기를 유지하기 위해 에러를 보상하며, 결과적으로 제안된 회로는 기존의 회로에 비해 약 $40\%$ 밝기 균일성을 재선한다.

In this paper, a 2 DOF haptic yawing joystick for use as the navigation input device in virtual environments is introduced. The haptic yawing joystick has 360° range for yawing motion and ±100° for pitching motion. The device can support weights of up to 26N for χ axis and 10N for axis with 10kHz of sampling rate. The size of the haptic yawing joystick is so small that it can be assembled on armrest of an arm chair and has relatively larger work space than other conventional 2 DOF joysticks. For the haptic yawing joystick, an ellipse navigation algorithm using the user's velocity in the virtual navigation is proposed. The ellipse represents the velocity of the user. According to the velocity of the navigator, the ellipse size is supposed to be changed. Since the path width of navigation environments is limited, the ellipse size is also limited. The ellipse navigation algorithm is tested in 2 dimensional virtual environments. The test results show that the average velocity of the navigation with the algorithm is faster than the average navigation velocity without the algorithm.

The purpose of this study is to examine the effects of job-related characteristics on alcohol consumption among female workers. The Data was collected from a sample of 1,000 female workers by a stratified proportional quota sampling method derived from those who were working in Seoul. Drinking behavior pattern includes total amount of pure alcohol consumed during the last month (AC) measured by graduated quantity-frequency. Job-related characteristics (JRC) were measured by job-related stress, work characteristics, and organizational structure including length of working hours, number of times dining out together with workers per year, number of staff to supervise, employment status, occupational category, and proportion of female workers to male counterpart. Confounding variables include sociodemogrphic and socio-cultural attitudes toward alcohol expectancy, subjective norm of drinking, and gender-role attitude. Hierarchical multiple regression models show that the variability of AC was accounted for by some JRC including number of times dining together and employment status, with confounding variables held constant. However, the relationship between AC and JRC varied across occupational categories. Some implications were discussed in terms of health policy for female workers and further study for female drinking behavior.

In this work, shape optimization of a wire-wrapped fuel assembly in a liquid metal reactor has been carried out by combining a three-dimensional Reynolds-averaged Navier-Stokes analysis with the radial basis neural network method, a well known surrogate modeling technique for optimization. Sequential Quadratic Programming is used to search the optimal point from the constructed surrogate. Two geometric design variables are selected for the optimization and design space is sampled using Latin Hypercube Sampling. The optimization problem has been defined as a maximization of the objective function, which is as a linear combination of heat transfer and friction loss related terms with a weighing factor. The objective function value is more sensitive to the ratio of the wire spacer diameter to the fuel rod diameter than to the ratio of the wire wrap pitch to the fuel rod diameter. The optimal values of the design variables are obtained by varying the weighting factor.

For the quality control of tablets several parameters have to be checked. The most important one is the content of an active ingredient which has to match a narrow range around the designated content. The only useful measurement mode is transmission which provides information of the complete tablet. A measurement in diffuse reflectance would register only the surface which is useless especially in case of a coated tablet. In this work tablets for a clinical study (placebo/verum studies) with very low concentrations of the active ingredient were measured. The concentration range was 0 to 6 mg with a total weight of the tablets of 105 mg, leading to a highest concentration of the active component of 5.7% by weight. Especially the spectroscopic distinction between the placebo and the low dosage forms with 0.25 and 0.5 mg active agent requires an extraordinarily accurate sampling technique. Using the VECTOR 22/N-T in transmission mode allows the collection of the information from the complete tablets. A quantitative PLS-model with transmission spectra from the tablets described above shows that the active substance can be predicted with a RMSECV (root mean square error of cross validation) of 0.04% absolute for this special application. The results are compared with those of measurements in diffuse reflectance using different accessories.
