Background: It has been suggested that engaging technology can empower individuals to be more proactive about their health and reduce their health risks. The aim of the present intervention was to study the effects of technology-aided testing and feedback on physical activity and biological age of employees in a middle-sized enterprise. Methods: In all, 121 employees (mean age $42{\pm}10$ years) participated in the 12-month three-arm cluster randomized trial. The fitness measurement process (Body Age) determined the participants' biological age in years. Physical activity was measured with the International Physical Activity Questionnaire Short Form. Results: Physical activity did not change during the intervention. Biological age (better fitness) improved in all groups statistically significantly (p < 0.001), but with no interaction effects. The mean changes (years) in the groups were -2.20 for the controls, e2.83 for the group receiving their biological age and feedback, and -2.31 for the group receiving their biological age, feedback, and a training computer. Conclusion: Technology-aided testing with feedback does not seem to change the amount of physical activity but may enhance physical fitness measured by biological age.

PURPOSE: The purpose of this study is to examine the relationship between the physical activities of individuals post-stroke and their HRQL, as well as to determine whether their functional abilities contribute to their amounts of physical activity. METHODS: The study's subjects included 90 individuals post-stroke. Their amounts of physical activity were measured using the International Physical Activity Questionnaire (IPAQ), and their HRQL was measured using the Medical Outcomes Study 36-Item Short-form Health Survey (SF-36). In addition, the functional abilities of the subjects were measured. For the measures of physical activities and the HRQL, Pearson's correlation coefficients were used to identify the strengths of the associations between the measures. A hierarchical linear regression model was used to determine whether physical activities had independent impacts on the HRQL. RESULTS: This study found that the physical activities performed by the subjects affected the SF-36 physical component score (PCS) (12%). However, the physical activities and the SF-36 mental component score (MCS) showed no statistically significant relationship, whereas functional abilities and physical activities had a statistically significant relationship (r = .57~.86, p<.001). CONCLUSION: The present study identified a correlation between physical activity and the PCS. Therefore, individuals post-stroke should be encouraged to carry out more physical activities, including more frequent walking activities.

The transition toward clean energy is an issue of great importance with growing debate in climate change mitigation. The complex nature of nuclear energy-CO₂ emissions nexus makes it difficult to predict whether or not nuclear acts as a clean energy source. Hence, we examined the relationship between nuclear energy consumption and CO₂ emissions in the context of the IPAT and Environmental Kuznets Curve (EKC) framework. Dynamic Auto-regressive Distributive Lag (DARDL), a newly modified econometric tool, is employed for estimation of long- and short-run dynamics by using yearly data spanning from 1971 to 2018. The empirical findings of the study revealed an instantaneous increase in nuclear energy reduces environmental pollution, which highlights that more nuclear energy power in the Indian energy system would be beneficial for climate change mitigation. The results further demonstrate that the overarching effect of population density in the IPAT equation stimulates carbon emissions. Finally, nuclear energy and population density contribute to form the EKC curve. To achieving a cleaner environment, results point out governmental policies toward the transition of nuclear energy that favours environmental sustainability.

Displacement cascade behaviors of Ti-6Al-4V alloys are investigated using molecular dynamics (MD) simulation. The embedded atom method (EAM) potential including Ti, Al and V elements is modified by adding Ziegler-Biersack-Littmark (ZBL) potential to describe the short-range interaction among different atoms. The time evolution of displacement cascades at the atomic scale is quantitatively evaluated with the energy of primary knock-on atom (PKA) ranging from 0.5 keV to 15 keV, and that for pure Ti is also computed as a comparison. The effects of temperature and incident direction of PKA are studied in detail. The results show that the temperature reduces the number of surviving Frenkel pairs (FPs), and the incident direction of PKA shows little correlation with them. Furthermore, the increasing temperature promotes the point defects to form clusters but reduces the number of defects due to the accelerated recombination of vacancies and interstitial atoms at relatively high temperature. The cluster fractions of interstitials and vacancies both increase with the PKA energy, whereas the increase of interstitial cluster is slightly larger due to their higher mobility. Compared to pure Ti, the presence of Al and V is beneficial to the formation of interstitial clusters and indirectly hinders the production of vacancy clusters.

Objectives This study analyzed the associations between mobile phone call frequency and duration with non-specific symptoms. Methods This study was conducted with a population group including 532 non-patient adults established by the Korean Genome and Epidemiology Study. The pattern of phone call using a mobile phone was investigated through face-to-face interview. Structured methods applied to quantitatively assess health effects are Headache Impact Test-6 (HIT-6), Psychosocial Well-being Index-Short Form, Beck Depression Inventory, Korean-Instrumental Activities of Daily Living, Perceived Stress Scale (PSS), Pittsburgh Sleep Quality Index, and 12-item Short Form Health Survey where a higher score represents a higher greater health effect. Results The average daily phone call frequency showed a significant correlation with the PSS score in female subjects. Increases in the average duration of one phone call were significantly correlated with increases in the severity of headaches in both sexes. The mean (standard deviation) HIT-6 score in the subgroup of subjects whose average duration of one phone call was five minutes or longer was 45.98 (8.15), as compared with 42.48 (7.20) in those whose average duration of one phone call was <5 minutes. The severity of headaches was divided into three levels according to the HIT-6 score (little or no impact/moderate impact/substantial or severe impact), and a logistic regression analysis was performed to investigate the association between an increased phone call duration and the headache severity. When the average duration of one phone call was five minutes or longer, the odds ratio (ORs) and the 95% confidence intervals (CIs) for the moderate impact group were 2.22 and 1.18 to 4.19, respectively. The OR and 95% CI for the substantial or severe impact group were 4.44 and 2.11 to 8.90, respectively. Conclusions Mobile phone call duration was not significantly associated with stress, sleep, cognitive function, or depression, but was associated with the severity of headaches.

The purpose of this study was to evaluate the relationship between lifestyle and health status among employees in a community. The participants were 199 white collar workers in J city. Data were collected from August 7 to 24, 2012 using the self-report questionnaire. Data were analyzed by descriptive statistics, t-test, ANOVA and Pearson coefficient correlation with SPSS/Win 17.0. There was a statistically significant correlation between lifestyle and health status(r= .164, p= .020). Mental component summary of health status was a statistically significant correlated with leisure activity(r= .270, p= .000) and regular exercise(r= .180, p= .011). Therefore, this study provided support for associations between lifestyle and health status. We suggest that strategies to emphasize leisure activity and regular exercise would be important for white collar workers to improve their mental health.

Aim: We conducted a study in China to assess the health-related quality of life (HRQoL) in patients treated on for malignant bone tumors after surgery, and investigate the possible determinants. Methods: The subjects were 120 patients surgically treated by amputation and limb-salvage for bone tumors during the period of June 2008 to June 2010. The Medical Outcomes Study Short Form 36 (SF-36) was employed to measure the HRQoL of all the patients before and after surgery. Results: With regard to the results of the general quality of life tool (SF-36), we observed a significant improvement of all the indexes of HRQoL after 6 months (p<0.05). PF, RP and BP scores showed significant increase between surgery after 6 and 12 months (p<0.05). The means of the HRQoL of bone tumor patients in our study were still much lower than those of general population in every domain, even 12 months after surgery. Logistic regression showed that female patients were found to have lower scores in physical component summary (PCS) than males (OR=0.64, 95% CI=0.35-0.89). Patients older than 15 years had lower scores in mental component summary (MCS) (OR=0.60, 95% CI=0.32-0.86). Ablative surgery was related to both lower MCS and PCS scores (For MCS, OR=0.54, 95% CI=0.31-0.83; for PCS, OR=0.43, 95% CI=0.25-0.73). Conclusion: Our study showed the treatment for bone tumor could greatly alter the HRQoL of patients. Age, sex and type of surgery were associated with physical or mental HRQoL after surgery.

The purpose of this study was to investigate moral reasoning among 77 senior medical students. Data were collected through selfreported questionnaires in June, 1995. The short form of the DIT (Rest's Defining Issues Test) was adopted to measure the stage of moral development, which was classified with the stage 2(instrumental relativist orientation), the stage 3(interpersonal concordance), the stage 4(law and order), the stage 5A(societal consensus), and the stage 5B(intuitional humanism), stage 6(universal ethical practice). In particular, the level of principled thinking(P) was measured by summing those scores of the stages 5A, 5B, and 6. The possible range of P is O to 95. The data were analyzed by t-test, ANOVA. The results were as follows. 1. The mean score of P(%) was 44.67 (SD=12.82). And the mean score of the stage 5A was higher than the scores of other stages. The mean score of P was not significantly different by general characteristics of the students. 2. The mean score of the stage 5B revealed significant difference by religion (3.17, P=.019) ; The score was highest in buddhist (8.0), which was followed by protestant (6.1), catholic (5.6) and no religion (4.7). 3. The mean score of the stage 4 revealed significant difference by educational background of mother (3.24, P=.017) ; the Score was highest in graduate school (25.0), which was followed by high school (14.1), under-graduate school (13.9), elementary school (12.4), middle school (8.3).
