A cross-sectional study was performed to evaluate the effects of chronic low-dose solvent on neurobehavioral performance of 118 male car painters. A control group of 113 workers matched for age was selected from different sections of the factory. The mean age and the mean duration of employment were 33 years and 6.7 years in both groups. Mean years of education were 11.4 years in car painters and 11.8 years in controls. Each worker completed a medical and occupational questionnaire and four tests of Swedish performance evaluation system. These included simple reaction time, symbol digit, digit span and finger tapping speed. Althougth the mean duration of employment was 6.7 years, comparison of mean performance showed a significantly poorer performance on simple reaction time (p<0.05), symbol digit(p<0.01) and digit span(p<0.05) in car painters. In univariate analysis, age and educational level contributed to poorer performance on symbol digit and digit span. Smoking appeared to slow finger tapping speed in car painters. Performance of four tests of car painters exposed to high level of solvent was poorer than that of car painters exposed to low level. In multiple regression models, controlling for age, alcohol, smoking and shift work, solvent exposure was found to be associated with performance of simple reaction time, symbol digit and digit span and exposure to high level of solvent was related to poorer performance of symbol digit and digit span.

This study was conducted to compare and analyze occupational stress and satisfaction levels of the nurses in two different units to provide data for effective nursing resource management. Survey was conducted in four hospitals in June 2019 and data was obtained from 62 nurses in comprehensive nursing service units (CNSU) and 62 nurses in general units (GU). CNSU nurses had higher level of job satisfaction than GU nurses. Contributing factors included pay, professional status, administration, autonomy, task requirements, and interaction. Job stress level was not significantly different between groups. GU nurses had higher stress levels from nursing practice, conflict with doctors, and patients and caregivers, while CNSU nurses had higher stress levels in working condition. Negative correlation was found between job satisfaction and stress in GU nurses, whereas not in CNSU nurses. Clear definition of task, smaller work load, appropriate reward, and educational support is suggested to enhance job satisfaction.

Purpose: The purpose of this study was to investigate the drinking behavior of university students in Jeju for the safe campus life. Methods: A self-reported questionnaire was completed by 549 students in 4 universities in Jeju. The data were analyzed by t-test, one way ANOVA, and multiple regression using SPSS Win 19.0 program. The questionnaire instruments consisted of Alcohol Use Disorders of Identification Test-Korea (AUDIT-K) and Life Stress Scale for College Students adapted by Chon. Results: The alcohol consumption rate of participants accounted for 96.2%. The binge drinking rate in female students were 33.9% and that in male students was 29.5%. The result by scoring AUDIT showed that 30.7% of participants were normal drinking group, 36.0% were hazardous drinking group, and 33.3% were estimated alcohol abuse group. The average score of stress was 1.45 by Likert 4 point scale. The female students tended to have more stresses than male. The most important influencing factors on drinking behavior were the first alcohol drinking(${\beta}=-.250$, p< .001), gender(${\beta}=.202$, p< .001), and relationship problem(${\beta}=.116$, p < .05). Conclusion: The drinking rate of university students revealed higher than that in other age groups. So the early systematic education is strongly recommended to prevent the physical and mental side effects.

Purpose: The objective of this study was to offer clinical primary data that it's aims to examine effects of transcranial direct current stimulation (tDCS) on cognitive function and biochemical change of rat with alzheimer's disease(AD) induced by injecting scopolamine. Methods: Subjects were instructed cognitive dysfunction model, rat of Sprague-Dawley system was injected with scopolamine and each experimental group was classified into three; group I (n=16) is non-treatment groups; group II (n=16) is applied with the tacrine; group III (n=16) is applied with the tDCS. The ziggurat task test was conducted to observe behavioral changes and cognitive function ability and 7, 14, 21, 28 days after the model. Acetylcholine Esterase (Ach E) activity was examined for biochemical assessment of which the results are followed. Results: Participants showed as to behavioral change, tacrine application group was the most significantly responded, following tDCS application group. As to biochemical change, same as above, tacrine application group was the most significantly responded, following tDCS application group. Conclusion: From these results, confirm that tDCS application to rat with alzheimer's disease leads to positive effects on behavioral, cognitive function changes, and biochemical changes, lasting for certain period of time. This study, in particular, tDCS, which can change excitability of brain cells non-invasively, could provide basic data that is useful as a new treatment way for the patients with cognitive dysfunction.

Background: Mobilization and cranio-cervical flexion exercise has been reported in reducing pain from cervical part and improving its motor function; also, has been represented that alleviate of neck pain and recover of neck muscles improve the normal gait performance. However, few studies have identified the effects of mobilization and exercise on pain and gait parameters with preceding issues. Objective: To examine the effects or changes of pressure pain threshold (PPT) and gait parameters in patients with chronic neck pain. Design: Cross-Sectional Clinical Trials Methods: Twenty patients with the history of neck pain (>3 months) performed the cervical mobilization and cranio-cervical flexion exercise. Gait parameters were assessed with wireless device and collected data were transmitted to the personal computer via Bluetooth. The PPT was measured posteroanterior direction at the prone position and the mean of subsequent three PPT measurements was used for the final analysis. Results: Both cervical central posteroanterior mobilization (CCPAM) (p<.000) and sling-based cranio-cervical flexion exercise (SBCCFE) (p<.000) group showed a significant increase in the PPT and the gait parameters, cadence (p<.023), was significantly increased in the CCPAM group, however slightly increased in the SBCCFE group. The comparison between the CCPAM and the SBCCFE groups after treatment did not show significant differences for the score on the PPT and gait parameters. Conclusions: This study suggests that CCPAM and SBCCFE increase PPT, cadence, and gait speed.

Highly Differentiated and segmented social insurance scheme in Taiwan shows its salient dimension of stratification, which has been considered as a general feature of conservative welfare regime. However, compared to Western conservative welfare states, Taiwan's social insurance scheme shows a distinct feature. First, Taiwan's social insurance scheme has offered a full coverage for various benefits. Secondly, Labor Insurance and Government employees' Insurance reveal distinct features of stratification. Labor Insurance has developed a universalistic system based on status equality and cross-class solidarity of working classes while Government employees' Insurance includes a myriad of occupational- and status-based programs. This article aims to articulate the historical origin of Taiwan's unique social insurance scheme and explains it as an unintended result of state's political intervention and various interests of each insured groups, especially, politically, economically, and ethnically conflicting identities of government employees and working classes.

Objectives: Chronic obstructive pulmonary disease(COPD) is an important cause of mortality in workers exposed to hazardous dust, such as crystalline silica or coal, and COPD is related to inflammation and oxidative stress in the lung. The aim of this study was to evaluate the association of oxidative stress and inflammation to COPD in retired workers exposed to mineral dust. Methods: The levels of malondialdehyde(MDA) in EBC as biomarkers for oxidative stress and C-reactive protein(CRP) and lactate dehydrogenase(LD) as biomarkers for inflammation were measured in 107 male subjects(63 pneumoconiosis and 42 COPD subjects). Results: Mean levels of EBC MDA(2.03 nmol/L vs. 4.65 nmol/L, p=0.010) and serum LD(170.3 U/L vs. 185.9 U/L, p=0.022) were significantly higher in subjects with COPD, but mean levels of serum CRP(p=0.469) did not show a statistical difference between the study groups. Level of EBC MDA was negatively correlated with ${%}FEV_1$ predicted(r=-0.279, p=0.004) and ${%}FEV_1/FVC$ ratio(r=-0.397, p<0.001). Conclusions: These results suggest that EBC is a useful biological matrix for investigation of respiratory oxidative stress. High levels of EBC MDA and serum LD are related to COPD in retired workers exposed to mineral dust.

Objective: Elevated cholesterol levels contribute to changes of the arterial endothelial permeability. Hyperlipidemia promotes atherosclerosis and is associated with an increased risk of stroke incidence. The purpose of this study was to investigate the effects of having a history of hyperlipidemia prior to a stroke incidence on postural balance, anticipatory dynamic postural control, gait endurance and gait performance in individuals with hemiparetic stroke. Design: Cross-sectional study. Methods: Fifty-two adults who were diagnosed with stroke 6 months ago or more were enrolled in this study. They were divided into two different groups according to hyperlipidemia history before stroke. All participants were assessed with the Activities-specific into Balance Confidence (ABC) scale, Berg Balance scale (BBS), Dynamic Gait Index (DGI), Timed Up and Go test (TUG), and the 6-minute walk test (6MWT). An independent t-test was used to analyze the difference between the hyperlipidemia group and non-hyperlipidemia group. Results: After analysis, the BBS, TUG, and 6MWT scores were significantly different between the hyperlipidemia and non-hyperlipidemia group, but not the ABC and DGI scores. Conclusions: The results of this study show that having a history of hyperlipidemia before stroke affects static and dynamic postural balance performance, anticipatory dynamic postural balance, and gait endurance in individuals with chronic hemiparetic stroke. Based on the results of this study, we also suggest treatment for hyperlipidemia should be implemented throughout the therapeutic interventions, such as pharmacological or exercise programs, in order to restore the physical function of stroke survivors.
