As large-scale computational applications in various scientific domains have been utilized over many integrated sets of grid computing resources, the difficulty of their execution management and control has been increased. It is beneficial to refer job history generated from many application executions, in order to identify application‘s characteristics and to decide selection policies of grid resource meaningfully. In this paper, we apply a statistical technique, Plackett-Burman design with fold-over (PBDF), for analyzing grid environments and execution history of applications. PBDF design identifies main factors in grid environments and applications, ranks based on how much they affect to their execution time. The effective factors are used for selecting reference job profiles and then preferable resource based on the reference profiles is chosen. An application is performed on the selected resource and its execution result is added to job history. Factor's credit is adjusted according to the actual execution time. For a proof-of-concept, we analyzed job history from an aerospace research grid system to get characteristics of grid resource and applications. We built JARS algorithm and simulated the algorithm with the analyzed job history. The simulation result shows good reliability and considerable performance in grid environment with frequently crashed resources.

Objectives: This study aimed to find gender distinctions in terms of the sociology of the population; to determine work-related factors; to analyze gender differences in daily living, work, sports, and art performances; and to identify gender-related factors that limited performance of daily living and work activities. Methods: A questionnaire was designed that included disabilities of the arm, shoulder, and hand (DASH), accident history, disease history, work duration at current workplace, marital status, job satisfaction, job autonomy, and physical demands of the job. Out of 1,853 workers surveyed, 1,173 questionnaires (63.3%; 987 males, 186 females) included responses to DASH disability and DASH optional work and were judged acceptable for analysis. Results: Upper extremity functional limitation during work and daily living was higher for females than males. The limitations for males increased according to their household work time, accident history, work duration, job satisfaction, physical demand, and job autonomy. Meanwhile, female workers' upper extremity discomfort was influenced by their disease history, job satisfaction, and physical demands. In addition, the size of the company affected male workers' upper extremity function, while marriage and hobbies influenced that of female workers. Conclusion: This study addressed sociodemographic factors and work-related factors that affect each gender's upper extremity function during daily living and working activities. Each factor had a different influence. Further studies are needed to identify the effect that role changes, not being influenced by risks at work, have on musculoskeletal disorders.

The purpose of the present study was to investigate the effects maternal employment history, achievement motivation and gender egalitarianism in job on university students' negative beliefs about the consequences of maternal employment. A total of 338 university students in Seoul, Kyungki, and Kyungnam area, provided information for the study. Analyses results showed that male students had higher level of negative beliefs about the consequences of maternal employment and achievement motivation and lower level of gender egalitarianism in job than female students did. Mothers' history of employment during the student's middle and high school period and higher job egalitarianism predicted lower negative beliefs about maternal employment. As male and female students were compared, male students with history of mothers' employment, lower level of achievement motivation and higher level of gender egalitarianism showed low level of negative beliefs about maternal employment. For female students, mothers' employment significantly predicted their beliefs about negative consequences of maternal employment.

This study was designed to analyze the results of bone mineral density test in oriental medical examination. The subjects were workers in the automobile manufacturing industry. The subjects consisted of 3,206 industrial workers who had received oriental medical examination by oriental medicine and they submitted questionnaires about drinking history and smoking history, during 9 months from March to November. They were categorized by sex, age, job class, drinking history, smoking history and exercise history. The T-scores were measured by using OSTEOPRO(BMTECH, Seoul, Korea). We analyzed the relationship between sex, age, job class, drinking history, smoking history, exercise history and the results of bone mineral density using X2-test of the SPSS Ver. 14.0. There was a positive correlation between age and osteoporosis prevalence. In job class, sales personnel were apt to have a higher prevalence of osteoporosis than factory workers and office workers. Osteoporosis rates of the drinker group showed a higher level than the non-drinker group. Bone mineral densities of non-smoker group were higher than the Smoker group. And bone mineral densities of exerciser group were higher than the non-exerciser group. They have to encourage exercise and educate the workers to quit smoking for their health promotion. Furthermore, continuous health check up needs to be done connectedly.

Purpose: The aim of this study was to investigate the association between job stress and metabolic syndrome among male workers. Methods: A total of 396 male workers employed in an electronic company, located in 'P' city, Gyeonggi Province, who had taken medical examination at the 'D' hospital, volunteered in this study. All the data used in this study were obtained from 'D' hospital after getting consent and permission from the workers. General and occupational characteristics, medical history, and health-related behaviors of the subjects were obtained by self-administered questionnaire. Results: The highest occupational stress by sub-sector was reported in the order of insufficient job control, organizational system, lack of reward, job demand, job insecurity, physical environment, job culture, and relationship conflict. The prevalence rate of metabolic syndrome of the participants was 19.9%. The results of the multiple logistic regression analysis on metabolic syndrome of the subjects indicated that the syndrome was significantly higher among those with family history, smoking habit and ex-smoking, working duration of 3 years and over, and with higher total score of occupational stress. It was significantly more prevalent, when the degree of stress was high in the sub-sectors of occupational stress; job autonomy, job insecurity, lack of reward, and job culture. Conclusion: In conclusion, it is necessary to implement a plan to efficiently manage the job stress of these male workers, as the probability of metabolic syndrome increased with the increase of occupational stress. Furthermore, considering the highest occupational stress was found to be job autonomy among its sub-sectors, it is necessary to prepare various measures to enhance the autonomy of such employees.

Background: This study aims to analyze the job stress of dental hygienists and the factors affecting somatization and to provide basic data for effectively managing job stress and somatization of dental hygienists. Methods: In this study, the data collected from 208 dental hygienists working in Jeollabuk-do Province were analyzed. Job stress was investigated using a questionnaire with 43 questions. In addition, the degree of somatization was evaluated through a simplified psychotherapy examination (Symptom Check List-90-Revision). Results: Age, employment history, position, average monthly income, night duty execution status, and perceived health status were significantly associated with job stress (p<0.05). The job stress sub-items scores based on general characteristics showed significance in 'workload' for those working a five-day workweek and perceived health status (p<0.05). Age, average monthly income, and perceived health status were noted in 'role conflict as a professional'. In 'lack of expertise and skill', it was noted that age, employment history, position, income, and night clinic were implemented. In 'improper treatment and interpersonal issues', level of education and perceived health status were significant (p<0.05). The higher the job stress, the higher the somatization symptom score (p<0.05), and the higher the job stress component, the higher the somatization symptom score (p<0.01). Conclusion: The job stress of dental hygienists should be reduced, and the symptoms of somatization should be mitigated. To improve the quality of medical services and the work efficiency of dental hygienists, proper treatment and compensation systems should be implemented for them to take pride as professional. Further, programs and regulations on mitigating job stress and somatization symptoms should be developed.

Objectives: This study was designed to analyze the results of body composition test by Oriental medical examination. The subjects were workers in the automobile manufacturing industry. Methods: The subjects consisted of 24,077 industrial workers who had received Oriental medical examination and completed questionnaires about drinking history and smoking history, during 9 months from March to November. They were categorized by sex, age, job class, drinking history and smoking history. The percentage of body fat(%BF) and abdominal obesity(AO) were measured by using bioelectrical impedance analysis (Jawon Medical, Seoul, Korea). We analyzed the relationship between sex, age, job class, drinking history, smoking history and %BF and AO using x$^2$-test of the SPSS Ver. 14.0. Results: Regarding the relationship between sex and %BF, AO, there was statistically significant difference as men had a significant higher level of %BF and AO than women. There was a positive correlation between age and both %BF and AO. Workers in their 40s especially showed a high level of AO. In job class, office workers and sales personnel were apt to have a higher level of %BF and AO than factory workers. %BF and AO of the drinker group showed a higher level than the non-drinker group. On the other hand, %BF and AO of the non-smoker group were higher than those of the smoker group. Conclusions: Companies should manage obesity closely and educate the workers to quit smoking for their health promotion. Furthermore, continuous health checkups need to be done systematically.

In this paper, we propose a location-based service that the user's location is known by connection history to WI-FI AP installed in a facility known its location previously. The location-based service proposed in this paper manages job processing states of technicians who inspect and maintain the facility like elevator by using worker's location and arrival time information. The job scheduling management method proposed in this paper is based on previously scheduled arrival time and actual arrival time to a target facility. And we experimentally implemented the inspection and maintenance system of an elevator to show the feasibility of job schedule management based on location and arrival time information acquired from Wi-Fi AP connection history. Our experimental implementation shows that our proposed method is usefulness in the field of the inspection and maintenance of a facility.
