Objectives: The aim of this study is to evaluate the association between vibration exposure and skeletal muscle mass index through a single university health check-up. Methods: We used data from 134,067 male subjects who received a general health check-up or vibration exposure health check-up out of the 1,515,322 people who underwent medical check-up at a local university hospital from 2002 to 2018. Pearson correlation analysis was conducted for comparing the association between skeletal muscle mass index and demographic and hematological variables in both groups. Mixed linear model analysis after controlling demographic and hematological variables was used to analyze the differences in skeletal muscle mass index between groups at every visit over 10 years. Results: In the Pearson correlation test, the variables that showed different results when comparing the two groups were C-reactive protein (p=0.001) and glycated hemoglobin (p=0.002) in the vibration exposure group and erythrocyte sedimentation rate (p<0.001) and vitamin D (p<0.001) in the general group. After the adjustment of demographic and hematologic variables, the skeletal muscle mass index at every visit was markedly decreased in the vibration exposure group (p<0.001). Conclusions: In the vibration exposure group, the skeletal muscle mass index showed a tendency to decrease markedly over time compared to the general health check-up group, which showed that C-reactive protein and glycated hemoglobin would have an influence on skeletal muscle index in male workers exposed to vibration.

Objectives: This study was to examine the features of work and posture analysis outputs in assessment of exposure to musculoskeletal disorder (MSD) risk factors in general hospital nurses. Methods: Work and posture analyses were carried out using observational approaches for nurses at general hospitals across Korea. With development of a taxonomy for assessing exposure to MSD risk factors, nursing tasks were documented in frequency (%time) for 8 hours a day in work analyses. Rapid Entire Body Assessment (REBA) scores were obtained for mode and maximum risk levels, respectively, during posture analyses. Results: A total of 27 nurses were observed while conducting 7 nursing tasks at 6 general hospitals. For both the work analyses and posture analyses, the taxonomy was developed and used. In the work analyses, 'Video display terminal task' and 'Nursing examination/ treatment' were the highest as 25%time for 8 hours a day, followed by 'Patient care' and 'Room rounding' as 13%time in order. In the posture analyses, the mode REBA scores were 2 or less for all nursing tasks while the maximum REBA scores were 7 for upper limbs at 'Room rounding' and 6 for trunk/neck/legs at 'Patient care'. Conclusions: The results showed the study nurses are occasionally at a risk for MSD, a medium level as designated in the REBA risk level, suggesting that it is important to control awkward posture at the nursing tasks such as 'Room rounding' and 'Patient care', in priority, for preventing MSD in the hospital sector including the study general hospitals.

Objectives: To determine the effect of the various type and number of shift work on sociopsychological stress in the university hospital nurses in Seoul, South Korea. Methods: Data was collected through a self-administered questionnaire that included general characteristics, the type and number of shift work in the past 4 weeks and the an sociopsychological stress based on PWI-SF. Logistic regression analysis was conducted to analyze the effect of shift work by types on sociopsychological stress of university hospital nurses using SAS 9.4 and it adjusted general characteristics by the additional models. Results: When the number of night shift work 3 or 4 compared to 0, sociopsychological stress was significantly high(OR=2.16, 95% CI=1.29-3.65). When 5 or more, it was higher(OR=2.39, 95% CI=1.55-3.72). Two continuous night shift work compared to 0 increased sociopsychological stress(OR=2.37, 95% CI=1.49-3.81) and 3 or more even more(OR=2.70, 95% CI=1.72-4.27). If the shift work type changes 14 or 15 times compare to below 11, sociopsychological stress is increased and even higher when 15 or more times but it's not significant after adjusting for covariates. Conclusions: It suggests that workplace with nurse expose to shift work should be on lookout for more than three night shift work, more than two continuous night shift work and more than 14 shift work change which can lead to burnout, absenteeism, depression and decreased productivity.

Objectives: Objectives of this study were: 1) to introduce industrial situation and health hazards of synthetic fiber, 2) to review a case of chronic obstructive pulmonary disease in a worker exposed to synthetic fiber reported to the Korea Occupational Disease Surveillance Center, and 3) to suggest supplementary measures for the occupational health system for workers exposed to synthetic fibers. Methods: Respiratory exposure, health hazards, and exposure standards for synthetic fiber dust in Korea and other countries were reviewed. In addition, a case of chronic obstructive pulmonary disease due to exposure to nylon dust reported to the Korea Occupational Disease Surveillance Center was reviewed and summarized. Results: The worker was a 53-year-old non-smoking male who had been involved in the nylon weaving process for 26 years. He had shortness of breath from three years ago. He was diagnosed with chronic obstructive pulmonary disease. PM1.0, PM_2.5, and PM10 were measured at 26.6 ㎍/m³, 48.2 ㎍/m³, and 91.7 ㎍/m³, respectively. Fiber components estimated as nylon fiber were detected in the microscopic examination of a solid sample. Conclusions: For workers exposed to synthetic fiber dust, special health examinations of the respiratory system, regular work environment measurement, and work environment management through workplace health management should be performed. It is necessary to research on health effects of synthetic fibers.

Objectives : To investigate the effect of overtime work on fatigue symptoms among Korean female workers. Methods : A total of 1,875 subjects were analyzed using the structured questionnaire, which was composed of overtime work, fatigue symptom, and background characteristics. Data analysis included multiple regression to test for a relationship of overtime work with fatigue symptom while statistically controlling for demographic and occupational variables. Results : Overtime work was more common in those with shorter work years of 3 or less than in those with longer work years. Overtime work was more popular in day workers than in shift workers. No significant difference of smoking and drinking state was observed between two groups. Subjective fatigue symptoms were significantly higher in overtime workers than in workers without overtime work. In a multiple regression analysis with significant control variables, overtime work was associated with 0.31 more fatigue symptom(p<0.001). Conclusion : Our findings suggest that overtime work may increase risks for fatigue symptom. Therefore, preventive strategies will be needed to control the negative effect of overtime work on health status of female workers.

Objectives : The purpose of this study was to understand how work environment and conflict level of dental hygienists affect turnover for the efficive manpower management of dental hygienists. Methods : Dental hygienists in dental (hospital)clinics near Daegu were randomly selected as the subjects of this study, and the followings analysis results are from 249 questionnaires: which were collected from March 2 to March 31 2011. Results : Among the 249 dental hygienists surveyed, 33.7% experienced turnover and 59.0% had turnover intention. From the analysis of the demographic, working environment and levels of conflict, dental hygienists had significantly higher turnover experiences based on following factors: older age, employment at a dental clinic rather than a dental hospital, longer working hours, longer total career as a dental hygienist, and longer of length of time at their current job. Furthermore, dental hygienists had significantly higher turnover intentions based on the following factors: younger age, more ignorant and higher level of discomfort due to conflict levels. Conclusions : Therefore, the working environment of dental hygienists has to be improved to inspire motivation, and conflict management has to be taughht within an organization to allow free communication and active participation in decision-making.

Purpose: The purpose of this study was to investigate nursing students' awareness and performance on standard precautions and to provide meaningful information for nursing students' education regarding hospital infection control. Method: Four hundred forty seven nursing students at 6 universities in D-city participated in this study. Data collection was conducted from March to April 2011. Students' awareness and performance on standard precautions of infection control in hospitals were measured using the modified 2007 CDC standard precautions guidelines. Data analysis was performed using the SPSS WIN 18.0 program, descriptive statistics, t-test, and ANOVA. Results: The level of students' awareness in the standard precautions was higher than performance. The higher levels of students' awareness and performance on standard precautions included patient care equipment, safe injection practices, and worker safety. The lower levels of students' awareness and performance on standard precautions included hand hygiene and personal protective equipment. There was no difference in the students' awareness and performance of standard precautions according to their characteristics. Conclusions: Based on the findings of this study, hand hygiene and personal protective equipment need to be stressed more within the program to improve nursing students' infection control techniques.
