ABSTRACT
Blue space is an important place for physical activity and provides physical and mental health benefits to residents. However, little is known about the mechanism of association between blue space and physical activity. Based on China National Knowledge Infrastructure and Web of Science Core Collection, the Chinese and English literature on the correlation between blue space and physical activity were selected and analyzed. The research field has the following characteristics so far: there are few studies on blue space in inland cities, developing countries, and vulnerable populations, and it is an emerging research field. Most included studies demonstrate positive effects of blue space exposure on physical activity, while studies conducted in different populations demonstrate population differences. The combination of multi-source data and multidisciplinary approaches should be an important foundation of this research field. Based on this, a research framework was proposed in this paper to analyze the complex association between them from a perspective of multi-dimensional characteristics, and blue physical activity was modeled as ecosystem services to explore the relationship between blue space and physical activity from a perspective of ecosystem service supply-demand and flow.
ABSTRACT
Objective@#To investigate sexual behavior and related factors among middle school students in Chengdu,and to provide a reference for improving the content and the way of their sexual health education.@*Methods@#Stratified cluster sampling was used to select 935 students from 11 schools in Chengdu. A self-designed questionnaire was implemented to estimate sexual behavior and related factors.@*Results@#Thirty-six (3.9%) students reported sexual behavior during the past year. The difference between boys (5.6%) and girls (1.7%) was of statistical significance(χ2=9.79，P<0.01). 77.8% (28/36) of all the participants reported first sexual contact experience, 2.4% (22/935) reported homosexual behavior. Five out of 935 students had experienced unplanned pregnancy, four of them chose to have an abortion. Multivariate Logistic regression showed that masturbation experience, talking about sex-related things with friends, asking for help from friends when in sex-related troubles positively with higher risk of sextual behavior(OR=6.67,0.30,0.28,P<0.05).@*Conclusion@#There are multiple types of unsafe sexual behavior among middle school students in Chengdu. Strategies including positive behavior support, peer education, sustainable environment and youth-friend services are essential for health education in the future.
ABSTRACT
Objective To understand the academic atmosphere current situation of graduate students and put forward relevant countermeasures to protect the academic integrity of graduate students.Methods The graduate student'scientific ethics and academic atmosphere construction situation of graduate students in 10 colleges and universities in Chongqing were investigated by questionnaire survey and analyzed.Results Through 1555 questionnaires,it was found that the average investment of time on scientific research in gruduate students was insufficient,the motivation of learning was complicated,and the situation of preventing academic misconduct was serious.Conclusion This study suggests that colleges and universities should establish an academic integrity security system for graduate students,including establishment of academic integrity system and specializing academic integrity supervision institutions,and strengthing academic integrity education.
ABSTRACT
After a literature review of the HPMC capsules, the research status of the HPMC capsules in vivo and in vitro are summarized, including the application status, the superiority over hard gelatin capsules and in particularly the disintegration release in vitro and bioavailability in vivo, as well as pharmacokinetics difference compared with conventional gelatine capsules, are explored in depth. Finally, the future applications of HPMC capsules are prospected.
ABSTRACT
Objectives: The prevalence of depression is relatively high in individuals with diabetes. However, screening and monitoring of depressive state in patients with diabetes is still neglected in developing countries and the treatment of diabetes-related depression is rarely performed in these countries. In this study, our aim was to study the role of diabetes education in the improvement of depressive state in newly diagnosed patients with type 2 diabetes
Methods: The Dutch version of the center for epidemiological studies depression scale [CES-D scale] and the problem areas in diabetes [PAID] questionnaire were used to assess depression and diabetes-specific emotional distress in 1200 newly diagnosed male adult patients with type 2 diabetes before and after a two-week diabetes education by professionally trained nurses. Pearson correlation and regression analysis were used to analyze the factors related to depression in patients with type 2 diabetes
Results: The incidence of depression in newly diagnosed patients with type 2 diabetes was 28%, and the rate of diabetes-specific emotional distress was 65.5%. High education levels, low income were correlated to depression in individuals with diabetes. After two weeks of diabetes education, the incidence of depression and diabetes-specific emotional distress decreased significantly to 20.5% [P < 0.05] and 11% [P < 0.001], respectively
Conclusions: The incidence of depression, especially diabetes-specific emotional distress, was relatively high in newly diagnosed patients with type 2 diabetes. The depression state could be improved by diabetes education
