Computers have millions of benefits and functions for their users, but excessive use of computers can also have negative impacts on health, one of which is Computer Vision Syndrome. Computer Vision Syndrome is an eye health problem commonly referred to as digital eye strain, which describes a group of problems experienced related to eye health and vision due to prolonged use of computers, tablets, digital magazines and cell phones. The research is quantitative descriptive research with a cross sectional approach. The research subjects used were all office workers at PT. XYZ, Pasuruan has 21 workers. From 21 samples, it is known that CVS occurred in section workers office PT. XYZ Pasuruan was 52.38% with the complaints most often felt by workers were dry eyes (66.67%), headaches or dizziness (52.38%), blurred vision (52.38%), and difficulty focusing when looking. short distance (47.62%). The incidence of CVS was found most frequently in female workers (80%), the duration of computer use was as long as≥ 4 hours a day (58.82%), eye position that is not at the same level as the computer (75%), and respondents who have a viewing distance of < 50 cm from the computer. (100%).

Development of a smart lumbar posture correction vest

Lack of proper lumbar posture is responsible for the occurrence of neck and shoulder pain, low back pain, and muscle and joint injuries in the abdominal region in more than 75% of individuals. This scenario is influenced by the excessive use of computers in the workplace, prolonged periods of incorrect sitting posture, inadequate posture during daily activities, and repetitive and localized movements, among other factors. Consequently, numerous studies are being carried out with the aim of reducing or eliminating the frequency of the problem. The most common solution proposed by researchers is the use of lumbar posture correction waistcoats. This article has automated a posture correction waistcoat that protects the wearer but also monitors their posture. When incorrect posture is identified, the waistcoat generates a warning signal. To do this, gyro sensors, accelerometer sensors, and vibration motors were installed and supervised by an Arduino microcontroller. A communication system based on Bluetooth technology was used, integrated into an Android app that interacts with the user, displaying monitoring data and providing graphical representations of inappropriate postures. In addition, a health and well-being module was implemented, which suggests a physical exercise routine to prevent back pain. In addition, a therapeutic massage module was included for relaxation and an interface for storing music that can be played while wearing the waistcoat. The results demonstrated that the implemented system generated a smart vest capable of monitoring and alerting the user when an incorrect posture was identified. Furthermore, the results indicated that the health and well-being module provided a positive user experience.

The effectiveness of auricular neuromodulation in childhood and adolescent obesity

detrimental to a child's health. This condition predominantly stems from an interplay of genetic, environmental, and lifestyle factors. Key contributors include unhealthy dietary habits, insufficient physical activity, and prolonged engagement in sedentary activities, such as excessive use of mobile phones, computers, and television. Childhood obesity predisposes individuals to a spectrum of health complications, including cardiovascular diseases, type 2 diabetes, and respiratory disorders. Additionally, it is associated with various psychological and social challenges. The rising prevalence of childhood obesity underscores its seriousness as a growing public health concern, with long-term implications for the health and well-being of affected children. Results: The review identified four surveys that met the predefined outcomes. These studies provided substantial evidence supporting the use of auricular neuromodulation in addressing childhood obesity. Each of the four studies was a randomized clinical trial, focusing on children and adolescents who underwent auricular neuromodulation. This procedure involved the use of vaccaria (plant seeds), metal pellets and mustard seeds. The participants in this study were divided into two subgroups. The first group received intervention with the use of vaccaria and the second group was the control group where there was no intervention. This design facilitated the comparison of the given intervention against alternative treatments. The primary outcome measures included anthropometric parameters and assessments of body image, self-esteem, and depressive symptoms. Conclusion: Recent studies have demonstrated that auricular neuromodulation using vaccaria seeds, mustard seeds and metal pellets yields positive results in treating childhood obesity. This conclusion is based on anthropometric outcome measures. These findings suggest that such neuromodulation techniques can be a viable option in the physiotherapeutic treatment of obesity in children and adolescents.

Altered Functional Connectivity of the Nucleus Accumbens and Amygdala in Cyber Addiction: A Resting State Functional Magnetic Resonance Imaging Study

Cyber addiction, which is more vulnerable in adolescents, is defined as the excessive use of computers and the Internet that causes serious psychological, social, and physical problems. In this study, we investigated the resting-state functional connectivity (rsFC) in adolescents with cyber addiction. We collected and analyzed resting-state functional neuroimaging data of 20 patients with cyber addiction, aged 13-18 years, and 27 healthy controls. Based on previous studies, the seed regions included the dorsolateral prefrontal cortex, medial orbitofrontal cortex, lateral orbitofrontal cortex, dorsal anterior cingulate cortex, insula, hippocampus, amygdala, nucleus accumbens, and the ventral tegmental area. Seed-to-voxel analyses were performed to investigate the differences between patients and healthy controls. A correlation analysis between rsFC and cyber addiction severity was also performed. Patients with cyber addiction showed the following characteristics: increased positive rsFC between the left insular-right middle temporal gyrus; increased positive rsFC between the right hippocampus-right precentral gyrus; increased positive rsFC between the right amygdala-right precentral gyrus and right parietal operculum cortex; increased negative rsFC between the left nucleus accumbens-right cerebellum crus II and right cerebellum VI. Adolescents with cyber addiction show altered functional connectivity during the resting state. The findings of this study may help us better understand the neuropathology of cyber addiction in adolescents.

CURRENT ASPECTS OF FORMATION OF VALUE ATTITUDE TO OWN HEALTH IN MEDICAL STUDENTS

The issue of health-care personnel’s preservation of health is extremely urgent today. Especially now, during the coronavirus pandemic, the modern health care sector requires significant expenditure of psychophysical resources of medical professionals, given the need to perform their professional duties at different times of the day and with different degrees of mental and physical exertion. Therefore, starting from the student years, it is important to organize the educational process with special attention to mental, physical and social well-being of each student in particular.
 During university years, students begin to realize the importance of their own health. Even if students care about their health, they pay attention to its physical component, but psychological and social health is not given a proper place in the system of their values. With age, a personal concern for own health increases significantly. At the same time some contradictions arise, as with growing up the behavioral activity, which provides its support, and strengthening, decreases. In addition, the period of reduced activity is the result of psychological mechanisms of self-defense, in particular, to mask personal experiences related to health.
 The content of educational and professional programs of medical specialties purposefully and indirectly influences the formation of individual and professional values, the leading place among which is rightly occupied by health concerns. The level of education of medical students, which is obtained by mastering integrated, general and professional competencies, significantly depends on their personal lifestyle choices and habits that affect the preservation of their own mental and physical health.
 The level of working capacity of students depends on a set of different factors: daily routine, nutrition, rest, sleep, the presence of unfavorable conditions for mental work, the level of compliance with the rules of culture of mental behavior, according to age. Emphasizes the health benefits of outdoor activities.
 The use of information technology in education, of course, significantly increases the efficiency of the educational process, optimizing the assimilation of educational material. However, with each passing day, there is a growing need to create a specific security system in education to predict and monitor the impact of information technology on the health of students as there is a probable threat to health due to excessive use of computers and other household appliances with different types of electromagnetic radiation.
 The formation of a value attitude to own health is an important component of the educational process in higher medical educational institutions, which was emphasized in this article. The problem of value attitude to own health is of great importance in modern research and practice of organizing the educational activities of student youth. A young person’s attitude to own health depends on a number of factors, including age, social status and level of education. It is the medical students’ deep awareness of the specifics of mental and physical health, factors of pathogenic influence on their condition is an effective feature in formation of the value attitude to their own health and has a significant impact on their daily behavior, building a trajectory of maintaining their own health in future professional activities.

Prevalence of Computer Vision Syndrome and Associated Factors among Instructors in Ethiopian Universities: A Web-Based Cross-Sectional Study.

Background In this globalized and high-tech era, the computer has become an integral part of daily life. A constant use of computer for 3 hours and more per day can cause computer vision syndrome (CVS), which is one of the leading occupational hazards of the 21st century. The visual difficulties are the most common health problems associated with excessive computer use. Therefore, this study aimed to assess the prevalence and associated factors of CVS among instructors working in Ethiopian universities. Methods A web-based cross-sectional study was conducted among 422 university instructors in Ethiopia from February 02 to March 24, 2021. A structured and self-administered questionnaire prepared by Google Forms was shared among instructors through their e-mail addresses, Facebook, and Telegram accounts. Data cleanup and cross-checking were done before analysis using SPSS version 23. A multivariable logistic regression was applied to identify factors associated with CVS using p value <0.05 and 95% confidence interval. Results Of the total 416 participants, about 293 (70.4%) were reported to have CVS (95% CI: 65.9–74.5%), of which 54.6% were aged 24–33 years. Blurred vision, pain in and around the eye, and eye redness were the main symptoms reported. Working in third-established universities (AOR = 8.44, 95% CI: 5.47–21.45), being female (AOR = 2.69, 95% CI: 1.28–5.64), being 44 years old and above (AOR = 2.73, 95% CI: 1.31–5.70), frequently working on the computer (AOR = 5.51, 95% CI: 2.05–14.81), and sitting in bent back position (AOR = 8.10, 95% CI: 2.42–23.45) were the factors associated with computer vision syndrome. Conclusions In this study, nearly seven-tenths of instructors in Ethiopian universities reported having symptoms of computer vision syndrome. Working in third-generation universities, being female, age, frequently working on the computer, and sitting in bent back position were statistically significant predictors in computer vision syndrome. Therefore, optimizing exposure time, addressing ergonomic hazards associated with computer usage through on-the-job and off-the-job training, and making the safety guidelines accessible for all university instructors would be critical to address the problem.

Association between digital smart device use and myopia: a systematic review and meta-analysis

Excessive use of digital smart devices, including smartphones and tablet computers, could be a risk factor for myopia. We aimed to review the literature on the association between digital smart device use and myopia. In this systematic review and meta-analysis we searched MEDLINE and Embase, and manually searched reference lists for primary research articles investigating smart device (ie, smartphones and tablets) exposure and myopia in children and young adults (aged 3 months to 33 years) from database inception to June 2 (MEDLINE) and June 3 (Embase), 2020. We included studies that investigated myopia-related outcomes of prevalent or incident myopia, myopia progression rate, axial length, or spherical equivalent. Studies were excluded if they were reviews or case reports, did not investigate myopia-related outcomes, or did not investigate risk factors for myopia. Bias was assessed with the Joanna Briggs Institute Critical Appraisal Checklists for analytical cross-sectional and cohort studies. We categorised studies as follows: category one studies investigated smart device use independently; category two studies investigated smart device use in combination with computer use; and category three studies investigated smart device use with other near-vision tasks that were not screen-based. We extracted unadjusted and adjusted odds ratios (ORs), β coefficients, prevalence ratios, Spearman's correlation coefficients, and p values for associations between screen time and incident or prevalent myopia. We did a meta-analysis of the association between screen time and prevalent or incident myopia for category one articles alone and for category one and two articles combined. Random-effects models were used when study heterogeneity was high (I2>50%) and fixed-effects models were used when heterogeneity was low (I2≤50%). 3325 articles were identified, of which 33 were included in the systematic review and 11 were included in the meta-analysis. Four (40%) of ten category one articles, eight (80%) of ten category two articles, and all 13 category three articles used objective measures to identify myopia (refraction), whereas the remaining studies used questionnaires to identify myopia. Screen exposure was measured by use of questionnaires in all studies, with one also measuring device-recorded network data consumption. Associations between screen exposure and prevalent or incident myopia, an increased myopic spherical equivalent, and longer axial length were reported in five (50%) category one and six (60%) category two articles. Smart device screen time alone (OR 1·26 [95% CI 1·00-1·60]; I2=77%) or in combination with computer use (1·77 [1·28-2·45]; I2=87%) was significantly associated with myopia. The most common sources of risk of bias were that all 33 studies did not include reliable measures of screen time, seven (21%) did not objectively measure myopia, and nine (27%) did not identify or adjust for confounders in the analysis. The high heterogeneity between studies included in the meta-analysis resulted from variability in sample size (range 155-19 934 participants), the mean age of participants (3-16 years), the standard error of the estimated odds of prevalent or incident myopia (0·02-2·21), and the use of continuous (six [55%] of 11) versus categorical (five [46%]) screen time variables INTERPRETATION: Smart device exposure might be associated with an increased risk of myopia. Research with objective measures of screen time and myopia-related outcomes that investigates smart device exposure as an independent risk factor is required. None.

The Effects of COVID-19 Process on Time Management of Foreign Language Teacher Candidates

In this study which was conducted to determine the effects of the COVID-19 process on time management of foreign language teacher candidates, qualitative design was used. The study group was formed by criterion sampling, which is one of the purposeful sampling methods. The criteria determined were for the participants to work, to have pedagogical formation training online, and to have previously had face-to-face training. Accordingly, 35 foreign language teacher candidates participated in the study. A semi-structured interview form consisting of five questions was used to collect the data. Content analysis technique was used in the analysis of the data and themes were reached from the codes. From the data obtained, it was concluded that the plans made about education in the COVID-19 process could not be followed due to the inability to perceive time, the process negatively affected time management as it created psychological pressure and wasted time, this changed the perception of time by making the time to pass quickly, that there were motivation problems arising from the focus and lack of explanations about the lessons and family factors and that time traps related to excessive computer use, watching movies-series, and excessive communication were encountered. At the same time, it was determined that the COVID-19 process has positive effects on preventing wasting time due to the traffic problem, creating a chance for individuals to spend more time for themselves and providing a more flexible studying environment. Regarding the negative effects of the COVID-19 process on time management, it is recommended that teacher candidates, who assume a great responsibility especially in the field of education, receive training on stress coping, distance education and time management in order to avoid or be affected less by the negative effects such as pandemics without field limitation.

The effect of computer use on the occurrence of migraine

Background/Aim. Risk factors concerning computer use-related migraine onsets are still unknown. The aim of this study was to determine the prevalence of headaches in computer users as well as the effects of computer use and behavior on the prediction of migraine presence. Methods. A cross-sectional study included 1,500 subjects from the general population who were given a questionnaire to assess the presence and type of headache and questions regarding computer-assisted behavior. All examinees were divided into two groups: the first group consisted of respondents who had a headache, and the second group consisted of subjects without a headache. Results. A total of 67.9% of the subjects had a headache, of which 23.9% had a migraine. Results of multinomial regression analysis showed that significant predictors of the migraine group, compared to the group without headache, were gender (female) and family anamnesis positive for migraine, as well as spending more time on the computer, making shorter and infrequent breaks in which physical activities were less included. Furthermore, members of the migraine group, compared with the group with other types of headaches, were younger and had family anamnesis, rarely made pauses during computer use, and their pauses were shorter. Conclusion. Improper and excessive computer use could be considered a risk factor for migraine occurrence, particularly in young people who have positive family anamnesis for migraine.

PC 사용자를 위한 인공지능 기반 거북목 경고 시스템 개발

In recent years, excessive use of laptop computers, tablets, smartphones, and other small portable digital devices has caused many side effects, including the FHP (Forward Head Posture) or the poking chin. It has been reported that FHP results in shoulder pain, neck ache, craniofacial pain, headache, or other adverse conditions. To prevent FHP, it is advised to consciously keep one’s head in an upright posture. This paper proposes a new FHP warning system, which can help a user maintain a good posture by signaling an alarm, when FHP is detected. The system consists of an FHP warning device, a measurement set, and a decision algorithm for FHP. Unlike previous studies and patents, the proposed system delivers the design that is comfortable for daily use (because it is not worn by a user) and highly accurate through the adaptation of an AI (Artificial Intelligence) algorithm. The warning device was created as a turtle doll, which neck and back is elongated and lighted by LEDs, respectively. The measurement set consists of a servo motor and two sensors that read the distances from the computer to the upper face and the chest with the angular displacement of the two parameters. To decide FHP, three popular AI algorithms that are relevant to the classification problem were considered and analyzed, namely the ANN (Artificial Neural Network), SVM (Support Vector Machine), and DT (Decision Tree). Measurement data were collected by 7 different users and 2 chairs with different heights for good posture and FHP scenarios. The test results of the trained algorithms yielded accuracy performances of 73.78%, 83.00%, and 86.26% for ANN, SVM, and DT, respectively. In this study, ANN’s poor performance due to various reasons (e.g., the small training sample size) was discussed. DT, which was suitable for a problem set of 0 or 1 discrete outputs, was selected for the FHP warning system.

All participants were initially required to have a physical examination, after which they complete a general situation questionnaire that included a headache screening question. Those who had suffered from headache within the previous year also completed the questionnaire developed by Lifting the Burden. The International Classification of Headache Disorders 3(ICHD-3) criteria was used for the diagnosis of headache.ResultsA total of 2012 valid questionnaires (males, 1544 [76.7%]; females, 468 [23.3%]) were obtained from 2216 participants for a response rate of 90.8%. A total of 619 participants were diagnosed with primary headache, the one-year prevalence of which was 30.8%. Regarding the classification of the primary headache, 152 participants suffered from migraine, with a one-year prevalence of 7.6%; 440 and 27 suffered from tension-type headache and unclassified headaches, with one-year prevalences of 21.9 and 1.3%, respectively. Multivariate regression analysis showed that female gender was a risk factor for migraine and tension-type headache (OR 3.21[95% CI 2.28–4.53] and 1.88[95% CI 1.47–2.40], respectively). Age was also related to migraine and tension-type headache. The 41–50 age group had 2.02 times the probability of migraine, and the 31–40 age group had 1.89 times the probability of tension-type headaches compared to the 18–30 age group. Obesity and excessive computer use (more than 12 h per day) were also factors contributing to tension-type headache (OR: 2.61[95% CI 1.91–3.56] and 1.63[95% CI 1.18–2.25], respectively).ConclusionsThe one-year prevalence of primary headache in this population was 30.8%. The prevalence of tension-type headache in this population was higher than that in the general Chinese population. The occurrence of primary headache is correlated with many factors, among which excessive computer use significantly contributed to the risk of tension-type headache.

A different approach to the use of elastic bands in the recovery of lower lumbar discopathy

Abstract Lower lumbar discopathies are in continuous growth among both young people and elderly. Causes that have led to an increase in the incidence of this pathology include: lack of exercise, nutrition, excessive use of computers and mobile phones, etc. The increased incidence of pathology led us to identify an attractive kinetotherapeutic treatment protocol that initially reduced the symptoms of this condition, and subsequently allowed the patients’ complete recovery. The present study was conducted on 33 patients diagnosed with lower lumbar discopathy. They received two evaluations, and between these, the patients performed a kinetic program consisting of elastic band exercises along with general neuroproprioceptive muscle relaxation techniques. The data obtained were inventoried and processed using statistical programs. The comparison of the initial and final results, as well as the data obtained from statistical processing showed an improvement of the symptomatology and the orientation of patients towards a complete recovery. Key words: lower lumbar discopathy, elastic bands, treatment protocol, statistical analysis
