Purpose : To identify trends in studies on the intersection of neurofeedback (NF) training and rehabilitation interventions for patients with stroke, as conducted over the past decade. Methods : This review included studies published from 2012 to 2022. A comprehensive database search was conducted using keywords such as "stroke", "electroencephalogram (EEG)", "brain wave", "nerve feedback", and "upper extremity function". Results : A total of 703 studies were initially retrieved. Of these, literature predating 2012, duplicate literature, non-experimental studies, and studies that did not target patients with stroke were excluded. After this screening, we retrieved the full texts of 15 articles and re-checked whether each study met the inclusion criteria of this study. The advisory members who participated in this study consisted of people with doctoral degrees and more than 5 years of clinical experience related to the rehabilitation of patients with stroke. Disagreements were resolved through discussions. Ultimately, 8 papers met the inclusion criteria and were included in the final analysis. Despite differences in the type and duration of NF training, the combination of NF training and rehabilitation intervention was found to be effective in promoting the functional recovery of the upper extremities, eliciting positive EEG changes, and inducing neurological changes in the brain. Conclusion : A meta-analysis involving a wider search range is needed in future studies. In addition, efforts are required to generalize the clinical application of these interventions. This can be achieved by supplementing the research methodologies through extensive review studies that encompass a diverse array of study designs.

Electronic educational environments in the conditions of quarantine restrictions of COVID-19 have become a common phenomenon for the organization of distance educational activities. Under the conditions of Russian aggression, Ukrainian proof of their use is unique. The purpose of the article is to analyze the role of electronic educational environments in the process of training applicants for higher education in Ukraine in the realities of a large-scale war. General scientific methods (analysis, synthesis, deduction, and induction) and special pedagogical prognostic methods, modeling, and SWOT analysis methods were used. In the results, the general properties of the Internet educational platforms common in Ukraine, the peculiarities of using the Moodle and Prometheus platforms, and an approximate model of the electronic learning environment were discussed. The reasons for the popularity of Moodle among Ukrainian universities are analyzed, but vulnerable elements related to security are emphasized. It was also determined that the high cost of Prometheus software and less functionality made this learning environment less relevant. The conclusions state that the military actions drew the attention of universities in Ukraine to the formation of their own educational platforms. This is especially relevant for technical and military institutions of higher education.

This study aimed to examine the general characteristics of individual workers, psychosocial working environment, and ergonomic risk factors which affect the status of musculoskeletal disorders. Self-report was carried out for musculoskeletal symptoms and ergonomic risks in working environment in 856 production workers in 16 small to medium sized manufacturing companies. Musculoskeletal symptoms were examined with a standardized questionnaire, and ergonomic risks were evaluated with a qualitative self-administered instrument for the tasks related to musculoskeletal disorders. Major findings were as follows: 1) Complaint rate for musculoskeletal symptoms was higher in female, aged, married workers with longer working hours, less leisure/hobby activity, longer household working hours and history of disease or accident. 2) Complaint rate for musculoskeletal symptoms was significantly higher in workers with dissatisfaction, difficult tasks, and no self-control at work. 3) Complaint rate for musculoskeletal symptoms was significantly higher in workers involved in tasks with major ergonomic risk factors, and handling heavy equipment. 4) Explanatory power increased the model with the musculoskeletal symptoms as dependent variable and demographic variables, psychosocial working environment and ergonomic risk factors included, and total explanatory power of 18.6% revealed the significant effect. Based on the results, we can conclude that musculoskeletal symptoms in manufacturing workers are associated with individual demographic characteristics, psychosocial working environment and ergonomic risk factors.

This study analyses the types, related operations, facilities, and causes of chemical accidents in Korea based on the RISCAD classification taxonomy. In addition, human error analysis was carried out employing different human error classification criteria. Explosion and fire were major accident types, and nearly half of the accidents occurred during maintenance operation. In terms of related facility, storage devices and separators were the two most frequently involved ones. Results of the human error-based analysis showed that latent human errors in management level are involved in many accidents as well as active errors in the field level. Action errors related to unsafe behavior leads to accidents more often compared with the checking behavior. In particular, actions missed and inappropriate actions were major problems among the unsafe behaviors, which implicates that the compliance with the work procedure should be emphasized through education/training for the workers and the establishment of safety culture. According to the analysis of the causes of the human error, the frequency of skill-based mistakes leading to accidents were significantly lower than that of rule-based and knowledge based mistakes. However, there was limitation in the analysis of the root causes due to limited information in the accident investigation report. To solve this, it is suggested to adopt advanced accident investigation system including the establishment of independent organization and improvement in regulation.

Objectives: An outbreak of acute febrile illness occurred in the Republic of Korea Air Force boot camp from May to July 2011. An epidemiological investigation of the causative agent, which was of a highly infective nature, was conducted. Methods: Throat swabs were carried out and a multiplex reverse transcriptase-polymerase chain reaction (RT-PCR) assay was performed to identify possible causative factors. Results: The mean age of patients who had febrile illness during the study period was 20.24 years. The multiplex RT-PCR assay identified respiratory syncytial virus (RSV) as the causative agent. The main symptoms were sore throat (76.0%), sputum (72.8%), cough (72.1%), tonsillar hypertrophy (67.9%), and rhinorrhea (55.9%). The mean temperature was $38.75^{\circ}C$ and the attack rate among the recruits was 15.7% (588 out of 3750 recruits), while the mean duration of fever was 2.3 days. The prognosis was generally favorable with supportive care but recurrent fever occurred in 10.1% of the patients within a month. Conclusions: This is the first epidemiological study of an RSV outbreak that developed in a healthy young adult group. In the event of an outbreak of an acute febrile illness of a highly infective nature in facilities used by a young adult group, RSV should be considered among the possible causative agents.

Purpose: This study was performed to investigate the present condition of drug abuse and its association with depression, self-rated health and health behaviors by job status in Korean adults. Methods: Data were derived from the study on four addiction problem and suicide in 2014. Multiple logistic regression was used to analyze patterns of drug abuse according to depression, self-rated health and health behaviors. Results: The prevalence of drug abuse during the past year was 17.1% of the 4,018 subjects. About 3.3 times risk for drug abuse was found among individuals who had high depression scores. The risk of drug abuse was higher among those who were smoking (OR:1.46, 95% CI:1.17~1.83), drinking more frequently (OR:1.30, 95% CI:1.07~1.58), sleeping insufficiently (OR:1.31, 95% CI:1.03~1.67), eating irregularly (OR:1.45, 95% CI:1.19~1.76). Drug abuse problem was detected more seriously among employed than unemployed adults. Conclusion: Health-related behaviors, such as smoking, drinking, sleeping, eating should be considered simultaneously when designing strategies to deal with drug abuse problem, and it is important to understand the interaction between drug abuse and mental health. Furthermore, workplace based intervention can be effective in solving drug abuse problem.

Purpose: This study was conducted to identify the association between emotional labor and job stress in bus drivers, as well as to propose management strategies for job stress. Methods: The study was conducted in February 2013 and involved 182 bus drivers working in the Gyeonggi area. Results: emotional labor was $9.5{\pm}2.34$ on average, and job stress was higher than the median of the same indicator among Korea's workers in the areas of physical environment, job autonomy, and relationship conflicts. Factors that affected job stress was lower if the subjects' Higher values for emotional labor indicated a higher level of job stress. Conclusion: To reduce among drivers, the following measures are necessary: increase the comfort of the driver's seat within the vehicle, provide adequate rest between bus headways, provide comfortable in-house rest facilities, and establish physical training spaces to reduce musculoskeletal disorders as well as programs for reducing back pain. In addition, relationship conflicts may be relieved by increasing job autonomy as much as possible, by granting autonomous control of working hours and bus headways, as well as by banning long work hours. Moreover, various club activities, exercise programs, and counseling programs that workers can be involved in together may be beneficial. This study is significant in that it identified the relationship of the bus drivers' emotional labor and job stress, which has previously been ignored as a research topic. Through its results, this study provides baseline data for the preparation of management strategies that can address the job stress of bus drivers.
