The One

Tractor drivers have quite often musculoskeletal problems because of bad sitting postures. It has been found that a good sitting posture is the one obtained when sitting on a horse with the hips in a muscle balanced rest position of 45°. A natural curvature of the spine is acquired as well as a perfectly balanced position in which the body obtains a good position of the centre of gravity. To improve the sitting posture of the driver of agricultural tractors, different types of saddle seats were adapted to fit in a tractor, and tested upon their comfort, work function and sitting posture. The saddle seats occupied less space in the horizontal plane compared to the conventional chair, and they were rotating freely during driving. Ten subjects employed as tractor drivers volunteered for the study. They harrowed and ploughed with three different saddle seats and one conventional tractor chair. Questions on experienced chair comfort and work function were asked. The drivers were video filmed from above and from the side in order to register their sitting posture. On a scale from 1 to 5 the conventional chair received a mean score of 3.6 and the saddle seats received mean score around 2. The difference is regarded to depend on differences in seat comfort. The saddle seats free rotation was mainly used during ploughing and reduced the spinal twisting 50%. The seat height adjusted by the tractor drivers was for the saddle seats 13 cm higher than for the conventional chair. This meant that the drivers received a sitting posture advantageous for the spine curvature. A future design of a tractor chair should have the possibility of varying raised sitting posture and free rotation. The seat should have a shape which gives a better seat comfort than any of the tested saddle seats.

It was reported high prevalence of musculoskeletal disorders among nurses. Among the wards, personnel working in Orthopedic wards routinely perform activities that require lifting heavy loads in awkward posture. Challenges faced by them assess patients skillfully and uniquely because orthopedic patients typically present with multiple, complex health problems. During orthopedic patient handling work-related postural strain are most common in health care unit personnel. This study aims at evaluating the different work-related musculoskeletal strain due to awkward postures, body parts discomforts, and find out some ergonomic solutions to these problems. Forty nurses working in orthopedic settings of two hospitals were interviewed by modified Nordic Questionnaire to reveal the prevalence of musculoskeletal problems and pain in various regions of the body. BPD Scale was used to identify the intensity of different body parts discomforts. Video recordings and still photographs were taken to evaluate postural stress during different activities were analyzed by OWAS (Ovako working posture analysis) method. Activity analysis chart was also used to represent the duration of different activities of nurses in their respective duty hours. It was observed that the most physically demanding and postural strenuous task is transferring patient alone. In orthopedics wards different activities like assist patient to walk, changing, other care works are strenuous because as about 90% of adult patient are over 50 kg of body weight and due to facture or other problem are unstable. Some ergonomic interventions like assisted lifting, lifting aids, training, etc. are recommended to improve the working conditions and reduce postural strain.

Abstract. Today it is necessary to analyze health and living conditions with the so-called Social and Economic Determinants approach as relevant variables to determine the healthy physical condition behavior of school children. The objective was to estimate the best predictive model of the Social Determinants of Health and of the healthy physical condition of Colombian school children. The present was a socio-sport study, through a quantitative descriptive statistical analysis. A total of 3458 school children aged 10 to 18 from 10 cities in Colombia participated. A survey was applied to establish the Social Determinants of Health and the healthy physical condition was objectively evaluated through the extended version of the ALPHA FITNESS battery. As results, the following were obtained: a higher percentage of 15-year-old men had a healthy physical condition, age, being active, unhealthy habits, leisure activities and body mass index, and socioeconomic level, coexistence and educational level showed a statistically significant association with healthy physical condition. It is concluded that the body mass index (BMI), the permanence of the father, the number of daily meals, being a beneficiary of a school restaurant, the number of hours that he sleeps at night, are the social determinants of health that are associated with the healthy physical condition variable, in turn, the binary logit model has a good predictive capacity (70.1%).

Rapid Entire Body Assessment

COVID-19 has become a global pandemic, and one of the government's actions in the education sector to prevent transmission through online class activities or online classrooms has been adopted. During the pandemic, it was discovered that using computers with improper or non-ergonomic body postures during online classes might cause muscular fatigue and raise the incidence of musculoskeletal problems. Using the Rapid Entire Body Assessment (REBA) method, this study seeks to detect musculoskeletal complaints and assess the posture of UMM students when using a laptop. Because online learning lasts more than 2 hours, posture that is not in accordance with the comfort of using a laptop can lead a person to exhaust more rapidly in front of a laptop for a relatively long period, especially in the upper neck, back, and waist, which stand for 80% of the body parts. This is supported by the study of respondents using a questionnaire distribution technique that provided a REBA score of 7 and a moderate risk level, indicating that remedial action is required. After a recommended improvement with a low risk level for MSDs, a REBA score of 3 was established. Suggestions that can be considered are that it is necessary to improve sitting work posture, it is recommended to work on a table and sit in a reclining chair so that the proposed work posture improvement can be carried out.

This study aims to determine and prove the appropriateness of theory with facts, the influence of work ethic and work discipline on employee performance. The quantitative method approach with an associative (causal) form is used in this study. The sample-based on the existing population is 103 respondents. The entire population is sampled with a non-probabilistic sampling technique that is a saturated sample. Data analysis techniques that use inferential statistics (parametric) with the data eligibility test include validity and reliability tests, tests of prerequisites or regression assumptions that are residual normality, multicollinearity, heteroscedasticity. The hypothesis test is performed using the F test, the t-test, the correlation analysis, the analysis of the coefficient of determination and the multiple regression equations. The results based on the series of tests can be concluded. The predictive variables of F (simultaneous) test results (work ethic and work discipline) have a positive and significant effect on the dependent variable (employee performance) the value of Fcount>Ftable (34,855>3.09). The results of the test of the importance of work ethic in the performance of employees have a positive and significant effect, the value of tcount>ttable (5,212>1.98). Similarly, labour discipline in the performance of employees has a positive and significant effect, the value of tcount>ttable (4,997>1,998). The magnitude of the correlation predictor variables, namely work ethic and work discipline on employee performance, obtained a number of 0.641, which means a strong correlation (0.600-0.799). The percentage coefficient of determination of the predictive variables (work ethic and work discipline) to the dependent variable (employee performance) is 39.9%, where 60.1% are other factors that are not identified. While the regression equation obtained Y = 0.799 + 0.428 + 0.432.

The structure of the human biological rhythm is most sensitive to changes that occur when you alter usual living conditions. That is why the authors of the work devoted their attention to the study of its basic parameters such as the analysis of the daily regimen, taking into account the “wakefulness and rest” cycles, the sleep quality index, the severity of insomnia. These parameters directly affect the person’s efficiency and results of sports activities. The authors have developed a system for the electronic diagnosis of human biorhythms. You can get acquainted with it at the open educational resources of V.N.Karazin Kharkiv National University. In the work, for the first time, the basic cycles of “wakefulness and sleep”, “activity and rest” were evaluated as basic cycles of the day regimen of students professionally involved in sports using electronic diagnostics. Insomnia severity index was evaluated, which directly affects the psychosomatic state and can be a cause of violation of the dynamic stereotype of a person, deterioration of health. These factors contribute to the development of desynchronosis. The data obtained indicate that the surveyed group of individuals can quite easily adapt to work both in the morning and in the evening, but it is likely that these individuals have unnatural types of daily working capacity, which are manifestations of adaptation to new living conditions. Also, this group of people is characterized by medium and high levels of sleep quality and body recovery. It is easier for people of this group to fall asleep in non-standard conditions than to stay awake at unusual time. Modern youth, despite an active (sporty) lifestyle, has certain violations in the duration and nature of sleep. The data obtained indicate that reducing the duration of sleep by 1.3–1.5 hours directly affects the state of wakefulness and sleep during the day. Despite the fact that chronic sleep deprivation in this group of students professionally involved in sports has not been identified, some individual variations in the need for quality of sleep are revealed, after a long sleep, there is minimal improvement in daytime wakefulness, reduction of fatigue, improvement in the processes of memory, perception and concentration. All these indicators directly affect the sports result. Compensation of lack of nocturnal sleep is mainly possible only due to longer breaks for rest during the day. Thus, the need for sleep is determined on the one hand by the processes of relaxation and fatigue, which increase during wakefulness, and the circadian process – the cycle of “activity and rest”. The level of need for sleep increases during wakefulness and decreases during sleep, while the circadian rhythm is an independent component under the control of the internal biological clock. Thus, the need for sleep at any given moment is a summation of the processes of “activity and rest”, “wakefulness and sleep” and internal biological clocks, and disturbances in the interaction of these processes explain subjective experiences associated with disruption of the daily rhythm at abrupt changes in the daily pattern and changes of length of daylight. Therefore, when the time of falling asleep falls on the period of activity and the person cannot fall asleep, and feels constant drowsiness during the day due to the growing need for sleep, this is a violation of the “wakefulness and sleep” cycle associated with new living conditions and stress loads on the body.

Sleep is a basic need for everyone. In conditions of rest and sleep, the body performs a recovery process to restore the body's stamina to be in optimal condition. The impact of lack of sleep causes a person to have difficulty concentrating, fatigue, headaches, feeling unwell, lazy, decreased memory, confusion, and has an impact on the ability to make decisions. The purpose of this study was to analyze the relationship between stress levels and sleep quality in the final undergraduate students of Public Health at Pahlawan Tuanku Tambusai University in 2021. This type of research was a descriptive correlation study with a Cross Sectional design. This research was conducted in July 2021.2020 with a sample of 60 final undergraduate students in Public Health, Tuanku Tambusai University, obtained using a total sampling technique. Data collection techniques using a questionnaire. Analysis of the data used is univariate analysis and bivariate analysis with Chi Square test. The results showed that there was a significant relationship between stress levels and sleep quality in final students with p value = 0.003. By conducting this research, researchers expect students to prevent stress that can affect sleep quality.

Background: Sleep is an important phenomenon to restore the body, both physically and emotionally, providing a state of balance in the person. It has been proven that adequate sleep at night is one of the main needs of older people in order to maintain an active and healthy life; among other factors, regular physical exercise can improve the quality of sleep. The aim of this research is to evaluate the effects of a physical exercise program supplemented with vibration training on sleep quality and the use of sleep drugs in women over 65 years of age. Methods: Fifty-two independent, physically active adult women were randomised into two groups: a physical exercise program (n = 26, control group) and the same physical exercise program supplemented with vibration training (n = 26, experimental group). The control group performed two weekly sessions of exercise, and the experimental group added another two sessions of vibration training to these two sessions for 12 weeks. Sleep quality was assessed using the Pittsburgh index. Statistical significance was established as p < 0.05. Results: After the intervention, there were significant changes to the quality of sleep (p = 0.001) and hours of sleep (p = 0.002) in the experimental group. The consumption of drugs decreased in this group, although not significantly; however, it did have a moderate effect size (p = 0.058; d = 0.36). The control group, on the other hand, reported significantly worsened sleep quality (p = 0.001) and increased drug use (p = 0.008). Conclusion: Three months of vibration training, as a complement to a conventional physical exercise program, improves sleep quality and reduces the consumption of sleeping pills in women over 65 years of age.
