  • Background: Fall-related injuries in older adults are a major health problem, and the risks and mechanisms of these injuries should be affected by race, culture, living environment, and/or economic status. Objects: Research articles have been systematically reviewed to understand fall-related injuries in older adults in South Korea. Methods: 128 published research papers have been found through the Korea Citation Index and the Korean Studies Information Service System, and reviewed in various perspectives, including incidents, fall death rates, medical costs, causes, injury sites and types, locations where falls occurred, prevention strategies, scholarly fields interested in fall injuries, and the role of physical therapy. Results: Fall-related injuries were found to be more common in women than in men, and the number of incidents increased with age, with the highest rate found in individuals over 85 years old. Risk of fall injury was associated with education level, comorbidities, and fear of falling. Common places where falls occurred included the bathroom, living room, stairs, and hallway. Common types of injury included bruises, fractures, and sprains in the lower extremities. Intervention strategies included exercise programs, education, and protective clothing. Scholarly fields interested in fall-related injuries in older adults included medicine, nursing, physical therapy, occupational therapy, physical education, pharmacology, oriental medicine, biomedical engineering, design, clothing, and textiles. Physical therapy intervention using proprioceptive neuromuscular facilitation has been used to improve one's balance. Conclusion: Any movement during the activities of daily living can lead to a fall. Physical therapists are highly educated to analyze human movements and should be involved in more research and practices to solve fall-related injuries in older adults.

  • Background: Korean Red Ginseng has been widely used in traditional oriental medicine for a prolonged period, and its pharmacological effects have been extensively investigated. In addition, Angelica gigas and deer antlers were also used as a tonic medicine with Korean Red Ginseng as the oriental herbal therapy. Methods: This study was conducted to evaluate the potential toxicological effect of KGC-HJ3, Korean Red Ginseng with angelica gigas and deer antlers, on reproductive and developmental functions including fertility, early embryonic development, maternal function, and embryo-fetal development. KGC-HJ3 was administered by oral gavage to Sprague-Dawley rats (22 animals per sex per group) at dose levels of 0 mg/kg (control), 500 mg/kg, 1000 mg/kg, and 2000 mg/kg to evaluate the potential toxicological effect on fertility and early embryonic development. In addition, KGC-HJ3 was also administered by oral gavage to mating-proven Sprague-Dawley rats (22 females per group) during the major organogenesis period at dose levels of 0 mg/kg (control), 500 mg/kg, 1000 mg/kg, and 2000 mg/kg to evaluate the potential toxicological effect on maternal function and embryo-fetal development. Results and conclusion: No test item-related changes in parameters for fertility, early embryonic development, maternal function, and embryo-fetal development were observed during the study period. On the basis of these results, it was concluded that KGC-HJ3 did not have toxicological potential on developmental and reproductive functions. Therefore, no observed adverse effect levels of KGC-HJ3 for fertility, early embryonic development, maternal function, and embryo-fetal development is considered to be at least 2000 mg/kg/day.

  • Construction has been well known as the industry in which accidents occur more often than other industries. The efforts to eliminate the accidents at construction sites need to be continuously conducted because they tend to cause the social problems such as massive loss of life and property. According to the Korea Occupational Safety and Health Agency (KOSHA), 26,570 (29.3 percent) out of 90,656 workers in total industrial accidents have been occurred in the construction industry in 2016. Particularly, the falling victims are the largest number, which is about 8,699. This number is increasing due to the increase of the large scale, high-rise, and complex construction structures and the various construction methods. In reality, there is a lack of analysis on the risk factors of safety accidents and preventive measures. Therefore, in this study, we have selected risk factors by analyzing the accident cases at construction sites. Based on the results, we conducted a safety practitioner-focused survey and had an interview with safety managers. In analyzing the cases, we have categorized them into three groups such as upper, middle, and lower and compared their statistical results. This study are expected to provide safety management guidelines with workers and safety managers to prevent previously fall accidents at construction site.

  • Musculoskeletal disorders affect workers' safety in most industries, and forest operations are classified as a musculoskeletal burden according to the Occupational Safety and Health Act in South Korea. In particular, felling and delimbing operations are mainly conducted by manpower, and then, it is necessary to evaluate ergonomic risk assessment for safety of felling and delimbing workers. Three ergonomic risk assessment methods, such as Ovako Working posture Analysis System (OWAS), Rapid Upper Limb Assessment (RULA), and Rapid Entire Body Assessment (REBA), are available for assessing exposure to risk factors associated with timber harvesting operations. Here, three ergonomic risk assessment methods were applied to examine ergonomic risk assessments in chainsaw felling and delimbing operations. Additionally, exposure to risk factors in each method was analyzed to propose an optimal working posture in felling and delimbing operations. The risk levels of these operations were evaluated to be highest in the RULA method, followed by the OWAS and REBA methods, and most of the exposed working postures were examined with a low-risk level of two and three without requiring any immediate working posture changes. However, two significant working postures, including the bending posture of the waist and leg in felling operation and standing posture on the fallen trees in delimbing operation, were assessed as the high-risk level and needed immediate working posture changes. Low-risk work levels were examined in the squatting posture for felling operation and the straightened posture of the waist and leg for delimbing operation. Moreover, the slope in felling operation and the tree height in delimbing operation significantly affected risk level assessment of working posture. Therefore, our study supports that felling and delimbing workers must operate with low-risk working postures for safety.

  • In this study, the purpose of this study was to analyze the degree of exposure of radiation workers assigned to the Department of Radiology and frequent visitors during on-campus practice, and to conduct a basic study on the feasibility and optimization of the radiation protection of the Nuclear Safety Act for the Department of Radiology. . The average exposure dose of occupational workers by year was 0.01 mSv, the lowest in 2014 and 2016. The highest figure was 0.12 mSv in 2018. The average exposure dose of frequent visitors by year was the lowest at 0.013 mSv in 2018, and the highest at 0.022 mSv in 2016. According to this study, the annual exposure dose received by professors, practical assistants, and students in the department of radiology (department) who use only radiation generators in the course of in-school practice is less than 1 mSv, which is the dose limit for the general public. Therefore, at the time when the radiation dose of students in the Department of Radiology is lower than the dose limit of the general public, the current safety regulation of the Nuclear Safety law is judged to be excessive regulation. Therefore, it is considered necessary to revise the regulations for radiation generators in the current Nuclear Safety law or to revise the radiation safety management system for university students.

  • Objective : The purpose of this study was to investigate the effect of brain-timing training using an Interactive Metronome (IM) on the reading abilities of children with low brain-timing abilities. Methods : A single-group pretest and posttest (retrospective study) were conducted in 8 children whose timing abilities were lower than that for their age average and who were trained from 2019 to 2021. Brain-timing training was conducted 2 or 3 times per week, with 70 sessions in total and 40-50 minutes per session, depending on the developmental characteristics of the child. Changes in brain-timing ability before and after the training were measured using the IM Long-Form Assessment (LFA), and reading ability was measured using the Basic Academic Skills Assessment:Reading (BASA:R). Results : On the basis of the results of the brain-timing ability evaluation using the LFA, the reaction times of all the children during motor tasks were decreased, resulting in statistically significant improvements in their brain-timing abilities (p < .05). Moreover, the raw scores in the BASA:R reading and fill-in-the-blank tests were significantly improved (p < .05). Conclusion : This study is meaningful in that it presents a clinical basis for brain-timing training to improve the reading abilities of children.

  • Building Ukraine as an independent, sovereign state requires the education of a citizen-patriot, able to live and work in a democracy, ensure the unity of Ukraine, feel constant responsibility for themselves, their people, country, seek to make a real contribution to the reform process. Modern modernization of the education system requires the search for new information and communication technologies that can ensure the formation of a citizen with an active civic position, which involves not only students mastering the rights and responsibilities of citizens, convincing them of the feasibility of democratic transformation of society, patriotic qualities and feelings, but also the identification of motivated civic actions. The pandemic and hostilities have led to significant changes in the field of education around the world, they have caused educational problems in Ukraine. At the beginning of the quarantine in the spring of 2020, all educational institutions in the emergency mode switched to distance learning. Intensive use of information and communication technologies in the life of modern society has led to a rethinking of the content of education and training of future professionals: the main role is played not so much by the information itself as the ability to work with it, critically comprehend and produce new knowledge; the main thing is not the amount of information, but its quality; information is needed for further practical application and transformation into knowledge, and the ability to work with information becomes one of the important competencies of the modern specialist in the new transformation of society: from information to the knowledge society. In this context, one of the main forms of training is distance learning, which is able to respond to the challenges of society. The main methodological positions that are taken into account in the construction of the structure and dynamics of the formation of civic responsibility of the individual during the use of information and communication technologies are highlighted. The structure of civil responsibility as a holistic system of information and communication technologies is outlined, which includes three subsystems that characterize the natural, social and systemic qualities of citizenship, interconnected hierarchically and synergistically.The constituent elements of the structural part of the model of civic culture of the individual are analyzed.

  • The aim of this study was to investigate the relationship between level of participation in children's play, empathy ability and coping behavior in mothers of children with disabilities. The study included 94 mothers of children with disabilities and the study was conducted from May 2018 to August 2018 based on the questionnaire about the level of participation in children's play, empathy ability and coping behavior. According to the study, Mothers of children with disabilities actively participate in physical play with their children and have a higher emotional empathy compared to cognitive empathy, and have acted to actively solve the problems for their children. When children have been treated for more than 1 to 2 years, the level of participation in children's play and the coping behavior were the highest. The longer their children's treatment period, the higher the mothers' empathy. The correlation between level of participation in children's play and coping behavior were significant. And empathy and coping behavior had a strong positive linear relationship. These results suggest that there are differences in level of participation in children's play, empathy and coping behavior depending on mothers' of children with disabilities general characteristics and the higher level of mothers' of children with disabilities participation in children's play, the more empathetic they have. When individualized intervention is provided, we look forward to providing professional service that take into account the characteristics of mothers of children with disabilities.
