OBJECTIVES: We wanted to investigate the relationship of shift work to the cardiovascular and gastrointestinal symptoms of Korean female workers. METHODS: The data was analyzed from a cross-sectional survey of 1,875 Korean female workers. Information was obtained about the shift work, the cardiovascular and gastrointestinal symptoms and the background characteristics. Multiple regression analysis was used to test for the relationship between the cardiovascular and gastrointestinal symptoms and the shift work variables, while controlling for the covariates. RESULTS: Shift work was more common for blue-collar workers than for office workers. A higher proportion of current smokers and drinkers was observed for shift workers than for day workers. A full-time job was more popular for shift workers than for day workers, while more day workers worked over 8 hours per day than did the shift workers. The mean scores of the cardiovascular and gastrointestinal symptoms were significantly higher for shift workers than for day workers. Shift work was associated with 0.54 more cardiovascular symptoms and with 0.38 more gastrointestinal symptoms on a multiple regression analysis (p=0.001; p=0.020, respectively). CONCLUSIONS: Our findings suggest that shift work may increase the risks for cardiovascular and gastrointestinal disturbances. Therefore, preventive strategies are needed to control the negative effects of shift work in the workplace.

PURPOSE: The purpose of this study was to identify the influencing factors on burnout after analyzing the relationship among clinical nurses' various perfectionism and coping styles. METHODS: A descriptive, cross-sectional study was conducted with 200 clinical nurses who had six months or more years of clinical experiences from two general hospitals located in D city. The data were analyzed by t-test, one-way ANOVA, Pearson's correlation coefficients, and stepwise regression analysis using IBM SPSS statistics 23.0 program. RESULTS: The burnout of clinical nurses was positively correlated with socially prescribed perfectionism and negatively correlated with active coping style. Socially prescribed perfectionism was positively correlated with active coping style and passive coping style. Influencing factors on the burnout of clinical nurses were socially prescribed perfectionism (β=.37), satisfied work unit (β=−.64) and neutral satisfaction of work unit (β=−.27), over 40 years of age (β=−.21), and active coping style (β=−.14). The model consisting of these variables explained 42% of variance of burnout in clinical nurses. CONCLUSION: Based on the findings of this study developing intervention programs that consider influencing factors such as perfectionism and coping styles is needed to reduce the level of burnout of clinical nurses.

BACKGROUND: The Occupational Safety and Health Monitoring and Assessment Tool (OSH-MAT) is a practical instrument that is currently used in the German woodworking and metalworking industries to monitor safety conditions at workplaces. The 12-item scoring system has three subscales rating technical, organizational, and personnel-related conditions in a company. Each item has a rating value ranging from 1 to 9, with higher values indicating higher standard of safety conditions. METHODS: The reliability of this instrument was evaluated in a cross-sectional survey among 128 companies and its validity among 30,514 companies. The inter-rater reliability of the instrument was examined independently and simultaneously by two well-trained safety engineers. Agreement between the double ratings was quantified by the intraclass correlation coefficient and absolute agreement of the rating values. The content validity of the OSH-MAT was evaluated by quantifying the association between OSH-MAT values and 5-year average injury rates by Poisson regression analysis adjusted for the size of the companies and industrial sectors. The construct validity of OSH-MAT was examined by principle component factor analysis. RESULTS: Our analysis indicated good to very good inter-rater reliability (intraclass correlation coefficient = 0.64–0.74) of OSH-MAT values with an absolute agreement of between 72% and 81%. Factor analysis identified three component subscales that met exactly the structure theory of this instrument. The Poisson regression analysis demonstrated a statistically significant exposure–response relationship between OSH-MAT values and the 5-year average injury rates. CONCLUSION: These analyses indicate that OSH-MAT is a valid and reliable instrument that can be used effectively to monitor safety conditions at workplaces.

BACKGROUND: This cross-sectional study assessed the sleep quality using the ActiGraph and investigated the relationship between the parameters of sleep assessment and the type of shift work in Korean firefighters. METHODS: The participants were 359 firefighters: 65 day workers (control group) and 294 shift workers (shift work group: 77 firefighters with 3-day shift, 72 firefighters with 6-day shift, 65 firefighters with 9-day shift, and 80 firefighters with 21-day shift). Sleep assessments were performed using the ActiGraph (wGT3X-BT) for 24 hours during day shift (control and shift work group) and night shift and rest day (shift work group). The participants recorded bed time and sleep hours during the measurement period. RESULTS: Sleep efficiency, total sleep time, and percentage of wake after sleep onset during night work were lower in the shift work group than control group (p < 0.05). Sleep efficiency decreased in night shift and increased in rest day, whereas wake after sleep onset increased in night shift and decreased in rest day (p < 0.05). Among shift work groups, sleep efficiency of 6-day shift was higher in day shift, and sleep efficiency of 21-day shift was lower in night shift than other shift groups (p < 0.05). CONCLUSION: We found that the sleep quality in night shift of the shift work group was poorer than the control group. As to the type of shift work, sleep quality was good in 6-day shift and poor in 21-day shift. Thus, fast rotating shift such as 6-day shift may be recommended to improve the sleep quality of the firefighters.

Introduction: In the Philippines, essential eye care services are not easily accessible especially for those in lower income groups, putting public elementary school students at risk for underdiagnosis of problems in visual acuity. The objective of this investigation was to determine prevalence of undetected refractive errors among public elementary students using the Welch Allyn Spot™ Vision Screener. Methods : A cross-sectional design was used in this investigation to estimate the prevalence of uncorrected refractive errors in the first grade students in San Perfecto Elementary School using Welch Allyn Spot™ Vision Screener (Photoscreener). Eligible students who gave informed consent and assent answered a questionnaire and underwent an eye examination. The prevalence of undetected errors of refraction were computed for the sample population and for selected demographic variables. Results : Approximately one out of four students (24.53%) had errors of refraction, with the most common type being astigmatism (22.64%), followed by myopia (3.77%) and hyperopia (2.83%). Conclusion This study revealed a high prevalence of undetected refractive errors among school-age children, higher than current published data (5%) in the Philippines.

PURPOSE: The purpose of this cross-sectional study was to assess the nutritional states and investigate the energy intake of tube-fed patients with severe neurodevelopmental disability. METHODS: Eighty six tube-fed patients with severe neurodevelopmental disability were studied. Heights were measured by flexible scale segmentally. Nutritional parameters of weight, triceps skin- fold thickness and mid-arm circumference were also measured. Total caloric intakes through the tube were calculated. RESULTS: The anthropometric results showed that nutritional states of tube-fed patients with severe neurodevelopmental disability were poor. The mean daily caloric intake was much less than daily energy requirement (mean=45.2% of requirement). The caloric intake was 7.2 kcal/height (cm), 57.0 kcal/weight (kg). Height was more related with caloric intake (r=0.476) than weight (r=0.263). CONCLUSION: These results provide that tube-fed patients with severe neurodevelopmental disability were growth retarded and their energy intakes were much less than daily energy requirements. The preliminary evidence was that they need adequate nutritional supply.

PURPOSE: The purpose of this study was to identify the moderating effect of leisure satisfaction on the relationship between job stress and job satisfaction. METHODS: A cross-sectional study was performed with 292 nurses having experienced shift work at least for 6 months. Data were collected from August to September in 2014. Descriptive statistics, t-test, correlation coefficient, and hierarchical regression analysis were performed. RESULTS: The study showed that job satisfaction was significantly correlated with job stress (r=.-320, p<.001) and leisure satisfaction (r=.317, p<.001). Leisure satisfaction had a significant moderating effect on the relationship between job stress and job satisfaction (F=25.087, p<.001). CONCLUSION: This study concluded that the role of leisure satisfaction may moderate the relationship between the two. That is, the nurses who perceived higher satisfaction on their leisure life tend to have higher satisfaction to their job even in stress situation. Therefore, the strategies for improving leisure satisfaction are needed to increase job satisfaction in stressful conditions.

PURPOSE: This study was a descriptive research to investigate the factors influencing nurses' turnover intention of Senior Convalescence hospitals in the metropolitan area. METHODS: A cross-sectional survey design was used. A questionnaire was distributed to the nurses in Senior Convalescence hospitals. The data of 210 nurses were analyzed using the descriptive statistics, t-test, ANOVA, Pearson correlation coefficient and multiple regression. RESULTS: Turnover intention was significantly correlated with professionalism, job involvement, organizational commitment, job stress, practice environment. Organizational commitment, job stress, age, and practice environment were identified as factors influencing turnover intention. These factors explained 53.3% of variance of turnover intention. CONCLUSION: The results suggest that strategies to decrease turnover intention should be discussed and continued to develop ways to establish organizational commitment, to lower job stress levels and to improve practice environment of nursing work. And further study is needed to identify the key mechanism in nurses' turnover intention of Senior Convalescence hospitals.
