Since democratic transition in the early 1990s, constitutionalism is getting more important for democratic consolidation in Africa. Using Afribarometer data set, this paper explains influences on public confidence in judiciary. High levels of public trust in judiciary is a necessary condition for judicial system to work effectively in emerging democracy. Unlike existing studies focusing on the function of judiciary and legal procedures, this paper is interested in the relationship between how ordinary Africans perceive the attitudes of the chief executive toward judiciary, the rule of law, and judicial corruption and their confidence in judiciary. The results show that those who think that the chief executive is likely to respect the constitution and the judiciary, that the law applies to everyone equally, and that there are few corrupt judicial personnel are likely to show high levels of confidence in judiciary. This study argues that the tension between laws and politics have a significant influence on transitional justice in emerging democracy.

The research is to be aimed how much the practice education could have influence on the critical thinking, the ability to work out problems and the confidence of nursing process. In order to collect the result, 4 scenarios had been applied into 41 of nursing student from March to July in 2014 (total 12 weeks). First of all, in the case of the critical thinking, its score($3.41{\pm}.31$) after being educated was remarkably higher than before($3.25{\pm}.26$). There was also no difference regarding the total score of ability to solve problems & nursing process confidence. However, the knowledge about nursing process, the identification of the relation causes and linkage regarding nursing process step account is after being educated were higher than before in subcategory. Although the changes regarding the ability to solve problems could not be identified with comparing before, the critical thinking and the confidence had been effected by the practice education with using the simulation. Thus, in order to identify the effect of the simulation education for further details, the more researches with the diversified subjects and the varied duration should be needed.

Background: The rise in telecommuting or non-face-to-face work owing to the coronavirus disease 2019 pandemic has fueled conversations regarding the "right to disconnect." Although evidence suggests that receiving work-related communications through telecommunication devices outside of work hours may lead to various symptoms and illnesses, limited research has been undertaken on these symptoms. This study therefore aims to investigate the correlation between receiving work communications through telecommunication devices after work hours and the occurrence of work-related headaches and eyestrain in full-time, non-shift white-collar workers. Methods: This study used data from the 6th Korean Working Conditions Survey. The frequency of using telecommunication devices for work purposes outside of working hours was divided into five categories: "Every day," "Several times a week," "Several times a month," "Rarely," and "Never." Work-related headaches and eyestrain were categorized based on a "yes" or "no" response to the survey questions. Descriptive statistics, χ² tests, and multiple logistic regression analyses were performed using SPSS 27.0. Results: After adjusting for sex, age, income level, education, occupation, workplace size, work hours, and sleep disorders, the odds ratio (OR) of work-related headaches and eyestrain based on frequency of telecommunication device usage were as follows: "rarely" (OR: 1.292; 95% confidence interval [CI]: 1.111-1.503), "several times a month" (OR: 1.551; 95% CI: 1.249-1.926), "several times a week" (OR: 1.474; 95% CI: 1.217-1.784), and "every day" (OR: 1.548; 95% CI: 1.321-1.813). Conclusions: Employees who use telecommunication devices for work after regular hours are more susceptible to experiencing work-related headaches and eyestrain compared to those who do not. However, there is a dearth of research examining the physical and mental health impacts of using telecommunication devices for after-hours work. Furthermore, the existing preventative measures in Korea are insufficient. Consequently, it is imperative to develop effective measures and conduct additional research to address this issue.

Background: Carpal tunnel syndrome (CTS) is a common work-related peripheral neuropathy. In addition to grip force and repetitive hand exertions, wrist posture (hyperextension and hyperflexion) may be a risk factor for CTS among workers. However, findings of studies evaluating the relationship between wrist posture and CTS are inconsistent. The purpose of this paper was to conduct a meta-analysis of existing studies to evaluate the evidence of the relationship between wrist posture at work and risk of CTS. Methods: PubMed and Google Scholar were searched to identify relevant studies published between 1980 and 2012. The following search terms were used: "work related", "carpal tunnel syndrome", "wrist posture", and "epidemiology". The studies defined wrist posture as the deviation of the wrist in extension or flexion from a neutral wrist posture. Relative risk (RR) of individual studies for postural risk was pooled to evaluate the overall risk of wrist posture on CTS. Results: Nine studies met the inclusion criteria. All were cross-sectional or case-control designs and relied on self-report or observer's estimates for wrist posture assessment. The pooled RR of work-related CTS increased with increasing hours of exposure to wrist deviation or extension/flexion [RR = 2.01; 95% confidence interval (CI): 1.646-2.43; p < 0.01: Shore-adjusted 95% CI: 1.32-2.97]. Conclusion: We found evidence that prolonged exposure to non-neutral wrist postures is associated with a twofold increased risk for CTS compared with low hours of exposure to non-neutral wrist postures. Workplace interventions to prevent CTS should incorporate training and engineering interventions that reduce sustained non-neutral wrist postures.

A survey was carried out from 143 cooks working at the deluxe hotels in Seoul to obtain the information on the working environment, characteristics, and the satisfaction of the cooks to improve the culinary art training program and the working environment. The results were as follows: Most of the cooks(58.7%) worked for 8-9 hours/day and 51.7% of the cooks earned 1-1.5 million won in a month. The cooks had average 1.6 licenses per person, however, their licenses accorded with their work place only with 85.3%. Subjects were unsatisfied with the pay(55.2%), but 42.7% of the cooks hoped to work in their current work place. If they could transfer to other work place, they wished to run a restaurant of their own. The unsatisfaction rate was high among the cooks worked for 10-15 years, and 19.2% of them was unsatisfied with the environment of work place and 11.5% was in promotion. The longer the working period of the cook, the higher the recognition of the culinary skill. Also, the more frequently transfer to other places, the higher the self-estimation in their skills. Subjects answered that the most important factors for good cooking are the good taste and hygiene. The quality of ingredients was recognized more important among the cooks worked for longer period. The greatest hindrance for the improvement of cooking skill was indicated as insufficient knowledge among the cooks worked under one year, lack of confidence among those worked for 2-5 years, and authoritarianism of seniors for 6-15 years. They answered that the most important qualification for cook is the sincere attitude. The cooks with under 5 years of experience indicated experience and studying attitude and the ones with over 6 years of experience culinary skill as the important factors for cooks. The important factors for promotion was pointed out as culinary skill and human relationship.

Background: Some working conditions may pose a higher physical or psychological demand to pregnant women leading to increased risks of pregnancy complications. Objectives: We assessed the association of woman's employment status and the industrial classification with obstetric complications. Methods: We conducted a national population study using the National Health Information Service database of Republic of Korea. Our analysis encompassed 1,316,310 women who experienced first-order live births in 2010-2019. We collected data on the employment status and the industrial classification of women, as well as their diagnoses of preeclampsia (PE) and gestational diabetes mellitus (GDM) classified as A1 (well controlled by diet) or A2 (requiring medication). We calculated odds ratios (aORs) of complications per employment, and each industrial classification was adjusted for individual risk factors. Results: Most (64.7%) were in employment during pregnancy. Manufacturing (16.4%) and the health and social (16.2%) work represented the most prevalent industries. The health and social work exhibited a higher risk of PE (aOR = 1.11, 95% confidence interval [CI]: 1.03-1.21), while the manufacturing industry demonstrated a higher risk of class A2 GDM (1.20, 95% CI: 1.03-1.41) than financial intermediation. When analyzing both classes of GDM, women who worked in public administration and defense/social security showed higher risk of class A1 GDM (1.04, 95% CI: 1.01, 1.07). When comparing high-risk industries with nonemployment, the health and social work showed a comparable risk of PE (1.02, 95% CI: 0.97, 1.07). Conclusion: Employment was associated with overall lower risks of obstetric complications. Health and social service work can counteract the healthy worker effect in relation to PE. This highlights the importance of further elucidating specific occupational risk factors within the high-risk industries.

Background: Shift work that interferes with normal sleep patterns, is known to be a cause of sleep disturbance and has been studied through various occupational groups. However, it is not known which shift type is better for sleep health. Methods: This study included 568 firefighters. Sleep quality was evaluated using Pittsburgh Sleep Quality Index. Sleep quality was categorized into 2 groups; good quality (≤ 5 points) and poor quality (≥ 6 points). Demographic variables, depression, anxiety, type of shift, and job were collected by self-reported questionnaires. The χ² test, t-test, and multiple logistic regression analysis were used to evaluate the effect of shift type on the sleep quality of firefighters. Results: Three hundred thirty-seven firefighters (59.3%) have poor sleep quality. Compared to day workers, the odds ratios (ORs) of poor sleep quality were 2.169 (95% confidence interval: 1.137-4.134) in 6-day cycle, 2.161 (1.150-4.062) in 9-day cycle, 1.805 (1.087-2.997) in 21-day cycle, and 1.485 (0.718-3.069) in 3-day cycle. The ORs of poor sleep quality were 1.697(1.021-2.823) in fire suppression and 2.325 (1.213-4.455) in emergency medical service compared to administration. Conclusions: All shift work type except for the 3-day cycle was associated with poor sleep quality compared to day work.

Background: Shift work has been reported to have several harmful effects on the human body. However, a small number of studies have evaluated the association between shift work and adverse effects on the thyroid. In our longitudinal study, we examined the causal association between shift work and the risk of hypothyroidism. Methods: A Kangbuk Samsung Cohort Study was conducted on 112,648 men without thyroid disease at baseline who were followed up at least once between 2012 and 2019. Shift work status and shift schedule types were categorized using standardized questionnaires. Hypothyroidism was defined using the reference ranges of serum thyroid-stimulating hormones and free thyroxine levels. Hazard ratios (HRs) and 95% confidence intervals (CIs) for incident hypothyroidism were estimated using Cox proportional hazards regression analyses with the daytime work group as the reference. Results: During the 501,237 person-years of follow-up, there were 6,306 incident cases of hypothyroidism (incidence density, 1.26 per 100 person-years). The multivariable-adjusted HR of incident hypothyroidism for the shift work total group that included all shifts compared with the daytime work group was 1.27 (95% CI: 1.15-1.40). For the fixed evening, fixed night, rotating shift, and other shift workers, the multivariable-adjusted HRs (95% CI) were 1.11 (0.76-1.61), 2.18 (1.20-3.93), 1.39 (1.23-1.56), and 1.00 (0.82-1.22), respectively. In subgroup analyses by age, the association between shift work and hypothyroidism was more pronounced in younger participants (< 40 years; HR: 1.31; 95% CI: 1.16-1.47). Conclusions: Our large-scale cohort study showed an association between shift work and the incidence of hypothyroidism, especially in younger workers with night shifts.

The purpose of this study is to examine the effects of work value of vocational counselors on organizational commitment and the mediating effect of job satisfaction. For this aim, this study conducted a survey concerning vocational counseling, work value, organizational commitment and job satisfaction targeting 207 vocational counselors in the Jeonbuk region. Analysis results found higher work value of vocational counselors resulted in higher organizational commitment. Second, concerning the relationship between work value and organizational commitment of vocational counselors, job satisfaction showed a significant mediating effect. Furthermore, in accordance with the type of work value, the relationship between organization commitment and both inherent and extrinsic work value had significant mediating effects on job satisfaction. Through this, the study confirmed that when vocational counselors recognize not only the inherent value of work is high, but also the extrinsic value such as benefits that could be obtained socially and economically through job, it is more likely to lead to increased organizational commitment. In particular, it was confirmed that extrinsic value is relatively more influential on job satisfaction and organizational commitment compared with inherent value. This indicates the importance of improving extrinsic value, such as material compensation and job stability, as well as inherent value, such as confidence and pride about the job, for increasing job satisfaction and organizational commitment.
