Effects of sports on school adaptability, resilience and cell phone addiction tendency of high school students

BACKGROUND Sport help promote healthy physical and mental development of high school students.To date,there have been few studies on the effect of sport on school adaptability,resilience and cell phone addiction tendency of high school students.AIM To explore the effects of sports on school adaptability,resilience and cell phone addiction of high school students.METHODS A stratified random sampling method was used to select 600 students from two high schools in Lhasa,and Physical Activity Rating Scale,School Adjustment Scale for High School Students,Chinese Adolescents Resilience Scale,and Mobile Phone Addiction Index were used for field questionnaire survey.RESULTS Sport was positively correlated with school adaptability and resilience(P<0.01),school adaptability was positively correlated with resilience(P<0.01)and cell phone addiction was negatively correlated with sports,school adaptability and resilience(P<0.01).The direct effect of sport on cell phone addiction was significant(P<0.001),accounting for 20.51%of the total effect.The mediating effect of school adaptability on sport and cell phone addiction was significant(P<0.001),accounting for 17.38%and 35.36%of the total effect value,respectively.School adjustment and resilience had a significant chain-mediated effect on sport and cell phone addiction(P<0.001),accounting for 26.75%of the total effect.CONCLUSION Sport affected the cell phone addiction tendency of senior high school students through the mediating effect of school adaptability and resilience,and through the chain mediation effect of both.

Impacts of cell phone use on driving safety and drivers'perception of risk

In this study, the factors influencing phone-related driving safety and drivers＇ perceptions of cell phone usage were analyzed. A representative sample of more than 500 licensed drivers in Texas who own a cell phone was interviewed based on a well-design questionnaire. Logistic regression model showed that the impact of using cell phone on driving safety varies depending on the characteristics of drivers, such as gender, age, driving experience, and use intensity. Additionally, the results indicated that the strong determinants of phone-related hazard are different from that of phone-related accidents. Regarding the drivers＇ perception of cell phone usage, there are two key findings. First, there is no explicit belief among the drivers about whether cell phone usage impairs driving safety regardless of the drivers＇ age, gender, driving education experience etc. Second, most of drivers have not realized that cell phone use while driving would increase their perception reaction time. Based on the analysis of these results, implications of cell phone use on driving safety along with some safety countermeasures, such as selective bans and non-cell phone zones, are discussed in the paper.

Is Long-Term Cell Phone Use Linked to Breast Cancer? A Review of the Evidence

Cancer of the breast is the second leading cause of cancer death among women worldwide. The majority of cancer of the breast cases (95%) is not hereditary. Can long-term cell phone use be linked to breast cancer? It is unlikely that electromagnetic radiation is involved, but it could possibly be due to the generated heat (cell phones only occasionally transmit when people are not talking on them). Therefore, is there any method or reported statistics that can be used to link the increasing breast cancer incidence with cell phone use and placement? Some young women who placed their mobile devices, including cell phones, in their bra believed that it caused their cancer because it was on the same side and in the same area their phone was adjacent to and came into contact with their skin for prolonged periods. This review highlights what is known about the link between cell phone use, which continues to increase rapidly, and breast cancer explores the association between prolonged exposure to non-ionizing radiation from cell phones and breast cancer. In conclusion, until more data are obtained concerning whether carrying a cell phone is associated with breast cancer, great care should be taken to avoid any potential risks. Strenuous efforts should be made to encourage users of cell phones to follow mobile device manufacturers’ recommendations, and if possible, to avoid skin contact until the potential risks, if there are any, are fully understood.

mHealth as a health system strengthening tool in China

Over the past 70 years,there was a rapid epidemiological transition in disease burden in China,from infectious disease to non-communicable diseases(NCDs),which requires long-term prevention and management.Rapid growth in mobile phone use,internet connectivity and digital health technology,presents new opportunities for improvement in NCD healthcare delivery and population-based outcomes.Although there were a growing number of research to evaluate the feasibility and effectiveness of the mobile health(mHealth)interventions for NCD management,the extent to which mHealth contributes towards the health system strengthening in China remains unknown.In this paper,we provided a high-level overview of mHealth in China and its role for Chinese health system strengthening.We conclude with several recommendations for the future of mHealth research in China based on existing evidence identified.

KELEA, Cosmic Rays, Cloud Formation and Electromagnetic Radiation: Electropollution as a Possible Explanation for Climate Change

The basic premise of this article is that human generated electromagnetic radiation is contributing to global warming. It may do so by diverting an energy force termed KELEA (kinetic energy limiting electrostatic attraction) from its presumed association with cosmic rays. Cosmic ray delivered KELEA is viewed as normally participating in the formation of cloud condensation nuclei (CCN). It may do so by transforming electrostatically inert particles into electrostatic aerosols capable of acting as CCN. The resulting clouds act as a reflective barrier to some of the infrared radiation from the sun and, thereby, reduce the earth’s heat. This article proposes that increasing levels of electromagnetic radiation in the atmosphere is reducing the capacity of cosmic rays to deliver adequate KELEA to maintain climate stability through optimal cloud formation. Specifically, the fluctuating electrical fields accompanying electromagnetic radiation may do so by competitively withdrawing some of the KELEA from the incoming cosmic rays. Previously described studies by Dr. Wilhelm Reich attributed to an energy force termed orgone, are consistent with weather activity being inducible using a device that likely delivers KELEA to the atmosphere. In addition to the foregoing consideration, there are many agricultural and industrial applications of KELEA activated fluids that can reduce carbon emissions. It is important that the scope of climate science be broadened to include a detailed understanding of KELEA and of its many potential practical applications in addressing global warming.

Relationship between using cell phone and the risk of accident with motor vehicles:An analytical cross-sectional study

Purpose Traffic accidents are one of the major health problems in the world,being the first cause of burden of illness and the second leading cause of death in Iran.The Sistan-Baluchestan province is one of the most accidental provinces of Iran with the highest rate of accidents-caused deaths.This study was conducted to determine the risk factors associated with traffic accidents in Zahedan through 2013 to 2016.Methods This analytical cross-sectional study was carried out on 223 drivers from Zahedan who were traumatized by traffic accident and sent to Zahedan hospitals.The data were obtained through interviews taken by the trained interviewers via refereeing to the medical records and collected in the researcher-made checklist.Census was obtained from the study subjects.For data analysis,independent t-test,one-way ANOVA,Chi-square and logistic regression were used with the Stata software version 11.0.Results In this study,223 male subjects with the mean age of(32.54±12.95)years,39.8%single and 60.2%married,entered for investigation.Most accidents(38.8%)occurred between 12:00 to 17:59.While driving,47.1%of the study subjects were using cell phones,89.1%had manual use of mobile phones,21.9%had a habit of sending short message service(SMS)and 23.4%had sent SMS within 10 min before the accident.The one way analysis of variance showed that the mean age of individuals with marital status,driving experience,education and accident with motorcycle were significantly different(p<0.05).Also,the multivariate logistic regression test indicated a significant relationship of smoking,ethnicity,insurance and SMS typing while driving with motorcycle accident(p<0.05).Conclusion In this study,SMS and smoking while driving had the highest risk among the variables studied in the motorcycle accidents.Therefore,effective education attempting to enhance people's awareness about the consequences of using cell phone and smoking during driving to reduce traffic accidents seems necessary.

An investigation on the link between driver demographic characteristics and distracted driving by using the SHRP 2 naturalistic driving data

Purpose–The purpose of this paper is to investigate the influence of driver demographic characteristics on the driving safety involving cell phone usages.Design/methodology/approach–A total of 1,432 crashes and 19,714 baselines were collected for the Strategic Highway Research Program 2 naturalistic driving research.The authors used a case-control approach to estimate the prevalence and the population attributable risk percentage.The mixed logistic regression model is used to evaluate the correlation between different driver demographic characteristics(age,driving experience or their combination)and the crash risk regarding cell phone engagements,as well as the correlation among the likelihood of the cell phone engagement during the driving,multiple driver demographic characteristics(gender,age and driving experience)and environment conditions.Findings–Senior drivers face an extremely high crash risk when distracted by cell phone during driving,but they are not involved in crashes at a large scale.On the contrary,cell phone usages account for a far larger percentage of total crashes for young drivers.Similarly,experienced drivers and experienced-middle-aged drivers seem less likely to be impacted by the cell phone while driving,and cell phone engagements are attributed to a lower percentage of total crashes for them.Furthermore,experienced,senior or male drivers are less likely to engage in cell phone-related secondary tasks while driving.Originality/value–The results provide support to guide countermeasures and vehicle design.

Use of social media while driving from an orthopedic resident's perspective

Purpose:To investigate the orthopedic injuries sustained while driving and using social media on cellular phones from an orthopedic resident's perspective.Methods:A total of 118 patients who presented with a history of road traffic accident secondary to social media usage and suffered from fractures were included in this cross-sectional study.These patients were reported from October 2018 to April 2019.We collected the data including the type of collision,type of social media usage during driving,location of injury,wearing of safety equipment's such as helmet and seat belt during driving.Results:The mean age of patients was(34.86±12.73)(range 15-71)years.The common types of accident on the basis of collision of vehicles were:car versus motorbike 45(38.1%),motorbike versus motorbike 28(23.7%),and motorbike versus pedestrian 22(18.6%).Most of the accidents(61,51.7%)occurred due to mistake of motor-bikers.Out of them,44(37.3%)occurred on traffic signals,followed by 29(24.6%)while driving on main roads.The common timing of accident was normal hours with frequency of 44(37.3%),followed by 39(33.1%)at late night.According to fracture type,closed injuries were 98(83.1%)and open fractures were 20(16.9%).The most common fracture was clavicular fracture(21,22.5%)followed by soft tissue injury in 19(16.1%)patients.The most common social media application usage during driving was Facebook 43(36.4%),followed by Whatsapp 24(20.3%),Google 19(16.1%),and Instagram 15(12.7%).Conclusion:This study provides evidence that social media usage while driving put the drivers and other road users'lives at high risk.The most common social media addiction while driving is Facebook and Whatsapp.So there is a need to make strict rules and penalties for using cell phone during driving so as to save the lives of drivers and other people using road.

Analysis of Microbiome DNA on Frequently Touched Items and from Palm Prints

Limited by the sensitivity of laboratory techniques,conventional human DNA analysis of touch DNA on frequently used items and prints does not always provide satisfactory results.In this study,microbiome DNA on personal computers,cell phones,and palm prints was analyzed and compared.After sample collection,DNA extraction,polymerase chain reaction amplification,library preparation,and sequencing,data were analyzed using the QIIME 1.8.0 software.Weighted unifrac distance between the right palm skin and the right side of a keyboard,the right palm skin and the mouse,and the left side of the keyboard and the left palm skin was 0.258850,0.265474,and 0.214098,respectively.Even after palm prints were left for 1 week,microbial community structures were still quite similar to those of samples collected from the palm skin on the day they were left(weighted unifrac distance was 0.270885).
