To investigate the affecting factors to the fatigue and subjective symptoms of adult women, the author analyzed the data from 300 women from 3 groups, manufacture workes, clerical workers and service workers, from august 31, 1993 to the September 30, 1993. Followings are the results there from. 1. For the physical symptoms of fatigue, more than 50 % of respondens comiained were "eye strain" with 73.7 %, "malaise" with 67.0 % "went lay down side" with 60.7 %, "yawing" with 60.3 % and "feel sleep" eith 50.3 % in that order. There was no statistically significant difference between labor woker group, but the fatiger rate was highest among office group. For the mental symptoms. There was no symptom over 50 % of responders complained. For the neurotic symptoms, more than 50 % of respondents complained were "backache" with 53.7 %, "headache" with 49.7 % "shoulder pain" with 54.0 % and "unconfortable" with 43.3 %, in that order, "backache" was higest in manufacture group, but the other symptoms were highest among office group. 2. For the most fatigue weekday, most women answered monday with 56.0 % thursday with 16.3 % and friday with 12.0 % in that order, but saturday was 2.0 %, and sunday was 2.05 labor worker group answered monday was the most fatigue day. 3. 37.7 % of respondents answered afternoon was the most fatigue hours, but 22.0 % was answered evening difference among groups. 4. Nothing to do with the general characteristics, such as age, residence, sleep hours, personality, health status, and exercise, and working conditons such as means to attend office, time to attend office, job satisfaction, work hours, and work years, the mean scores of subjective symptoms of fatigue was highest among office group.

Background: The purpose of this study was to analyze the associations between physical therapists' work-related musculoskeletal pain, quality of life (QoL), and presenteeism. Methods: Self-reported questionnaires were given to 402 physical therapists in Korea. Variables examined included the prevalence of pain sites related to work, pain intensity, pain pattern, pain frequency, pain duration, pain rating score (PRS), general characteristics, QoL, and presenteeism. Results: Of the 314 physical therapists who responded, 251 (79.9%) reported work -related musculoskeletal pain in at least one body part. The most affected regions included the wrist and hand (21.0%), shoulder (19.6%), and lower back (19.1%). On average patients, QoL and presenteeism differed significantly between physical therapists who reported pain and those who did not (P < 0.05). QoL showed a negative correlation with the work-related musculoskeletal pain (P < 0.01) and presenteeism (P < 0.01), while the presenteeism and work-related musculoskeletal pain showed positive one(P < 0.01). Factors influencing a physical therapist's QoL included presenteeism, Working venues (Convalescent hospital), Work status (Contra ct worker) and professional experience, while the presenteeism included QoL, work status (Intern), PRS, working venues (Convalescent hospital), Area of specialty (Pediatrics), age, sex and working hour. Conclusions: Results show that physical therapists appear to be at a higher risk for work-related musculoskeletal pain. Therefore, administrators need to use the intervention strategies to manage the presenteeism and QoL of physical therapists.

Validation and Standardization of neurobehavioral instrument in Korean occupational setting has not been studied ever. This study tried to validate the newly developed computerized psychomotor tests, Neurobehavioral Tests for Occupational Screening (NTOS). Male patients with Parkinson's disease(n=12) and male workers who never exposed to occupational neurotoxic materials and didn't have neurologic disease(n=21), performed some tests from NTOS; simple reaction time, choice reaction time(2 choice), and finger tapping(both hands). In simple analysis, difference between patient group and worker group was significantly great. Adjusted for age and education years, simple reaction time and finger tapping(both hand) were statistically significantly different between two groups(p<.05). Choice reaction time was also different(p<.1) but error frequency of choice reaction time test was not. Generally, this results showed NTOS could detect impairment of psychomotor function. But insensitive results of choice reaction time was partly due to small sample size and confounding variables and so required future study and refinement at improvement of NTOS.

This study was conducted at five Ethylene Oxide(EO) sterilizing processes in hospitals located in Seoul from August 8 to August 30, 1994. The main purposes of this study were to assess the TWA(Time Weighted Average) and short term exposures to EO and to evaluate factors affecting EO concentrations in sterilizing room. Results are summarized as follows. 1. The TWA concentrations of the sterilizing operators ranged from <0.005ppm to 3.04ppm and those of two sterilizing rooms out of five exceeded 1ppm, the Korean and ACGIH standards. 2. When the door of the sterilizer is opened at the end of the sterilization cycle, the short term concentrations of operators ranged from <0.005ppm to 11.4ppm, and those of three sterilizing room out of five exceeded 5ppm, the ACGIH short term exposure limit(STEL). The short term concentrations of area samples ranged from 0.24ppm to 49.2ppm and those of four sterilizing room out of five exceeded 5ppm. 3. Factors affecting EO exposure level were aeration type, the location of storage site for sterilized item, amount of gas, use period of sterilizer(p<0.005). 4. Following recommendations are suggested to minimize exposure to EO. The use of EO gas should be reduced by using another available sterilization methods, and the sterilizers and gas tank storage site should be isolated from, other work areas. Combination of local and general ventilation system should be installed. Metal carts or baskets for sterilization load should be used, and work environment and medical monitoring should be performed regularly.

The purpose of this study was to analyze turnover intention among non-regular workers in university hospitals. The data was 292 non-regular workers in 7 university hospitals from December 1 to December 31, 2017. ANOVA, t-test were used for analysis of difference by general characteristics, and multiple regression analysis was performed to analyze the effect on turnover intention. The results of the study are as follows. Unjust working environment, employment instability, discrimination experience were found to have a positive(+) effect on turnover intention. Job satisfaction, age, employment type had a significant negative(-) effect on turnover intention. In particular, high discrimination experience of non-regular workers, who occupy a large part of the hospitals in the increasingly competitive medical market, and high turnover intention can be a negative impact on good medical service and hospital management. The government should establish policies for non-regular workers and hospitals need practical changes in welfare, wages and working environment for non-regular workers.

Objectives: This study was designed to investigate whether long-term, low-level exposure to monocyclic aromatic hydrocarbons (MAHs) induced insulin resistance. Methods: The subjects were 110 male workers who were occupationally exposed to styrene, toluene, and xylene. One hundred and ten age-matched male workers who had never been occupationally exposed to organic solvents were selected as a control group. Cytokines, which have played a key role in the pathogenesis of insulin resistance, and oxidative stress indices were measured. Assessment of exposure to MAHs was performed by measuring their ambient levels and their urinary metabolites in exposed workers, and the resulting parameters between the exposed group and non-exposed control groups were compared. Results: There was no significant difference in general characteristics and anthropometric parameters between the two groups; however, total cholesterol, fasting glucose, fasting insulin, and homeostasis model assessment of insulin resistance levels were significantly higher in the exposed group. Phenylglyoxylic acid levels showed significant association with tumor necrosis factor-${\alpha}$, total oxidative status, and oxidative stress index via multiple linear regression analysis. Further, there was a negative correlation between methylhippuric acid levels and total anti-oxidative capacity, and there was a significant relationship between MAHs exposure and fasting glucose levels, as found by multiple logistic regression analysis (odds ratio = 3.95, 95% confidence interval = 1.074-14.530). Conclusion: This study indicated that MAHs increase fasting glucose level and insulin resistance. Furthermore, these results suggested that absorbing the organic solvent itself and active metabolic intermediates can increase oxidative stress and cytokine levels, resulting in the changes in glucose metabolism and the induction of insulin resistance.
