Understanding obesity in children is crucial because it can lead to adulthood obesity and result in fatal chronic diseases. Distinctive factors associated with obesity in adults have been described, but distinctive factors related to children remain unclear. We analyzed the correlation between the percentage of body mass index and lifestyle habits by conducting surveys on physical, nutritional, and psychological factors, and we used annual physical examination data to compare different traits among elementary school students (n = 197) and middle school students (n = 461). Our study revealed that the computing hours in elementary school students with overweight and obesity were significantly correlated with the percentage of body mass index (r = 0.29 on school days and r = 0.35 on days off, all P 0.05) in the computing hours of middle school students with overweight and obesity. Childhood obesity can cause depression and reduce children's quality of life because of their distorted body perception. In conclusion, physical factors directly affecting childhood obesity and psychological and environmental factors surrounding a child should be considered.

Viral hemorrhagic septicemia virus（VHSV） and marine birnavirus（MABV） are the causative pathogens for some of the most explosive epidemics of emerging viral diseases in many Asian countries, leading to huge economic losses in aquaculture. Rapid molecular detection for surveillance or diagnosis has been a critical component in reducing the prevalence of pathogen infection. The loop-mediated isothermal amplification（LAMP） of DNA is currently one of the most commonly used molecular diagnostic tools, as it is simple, quick, and easy to amplify target DNA under isothermal conditions. In the present study, a novel and highly specific LAMP assay for the sensitive and rapid detection of VHSV and MABV infection in fish was developed. Using a set of synthesized primers matching a specific region of the genome, the efficiency and specificity of the LAMP assay were optimized in terms of the reaction temperature and DNA polymerase concentration, as they are the main determinants of the sensitivity and specificity of the LAMP assay. In particular, we demonstrated that our assay could be applied to efficient detection of VHSV and MABV infection in the wild fish, Paralichthys olivaceus. Our results demonstrate the simplicity and convenience of this method for the detection of viral infection in aquatic organisms.

Objective： To examine the effect of acupuncture on Zhubin （KI9） in reducing alcohol craving in alcohol-dependent patients. Methods： Twenty male alcohol-dependent patients were randomly assigned to two groups, a treatment group （10 cases, age 43.0 ± 6.8 years） and a placebo group （10 cases, age 44.5 ± 7.9 years）. The treatment group was treated with real needle acupuncture on Zhubin （KI9） twice a week for 4 weeks, and the control group was treated with placebo needle acupuncture. Both groups were given acupuncture treatment using Park Sham Device （PSD）. Alcohol craving was measured by the Visual Analogue Scale （VAS） before treatment to establish a baseline, and after 1, 2, and 4 weeks of treatment. Repeated measures ANOVA was used to determine the main and interaction effects of time and on the outcome measure （VAS）. Results： There was a significant effect of time on VAS score （dr=3, F=13.3, P〈0.01）. Main effect of group on VAS score was significant （df=1, F=10.9, P〈0.01） and the time × group interaction was also significant （df=3, F=4.7, P〈0.01）. Conclusions： Real-needle acupuncture therapy on Zhubin （KI9） showed effectiveness in reducing alcohol craving. These results strongly suggest the usefulness of acupuncture therapy on Zhubin （KI9） in preventing a relapse in alcohol dependent patients.

In this study, compatible taper and stem volume equations were developed for Larix kaempferi species of South Korea. The dataset was split into two groups： 80% of the data were used in model fitting and the remaining 2o% were used for validation. The compatible MB76 equations were used to predict the diameter outside bark to a specific height, the height to a specific diameter and the stem volume of the species. The result of the stem volume analysis was compared with the existing stem volume model of Larix kaempferi species of South Korea which was developed by the Korea Forest Research Institute and with a simple volume model that was developed with fitting dataset in this study. The compatible model provided accurate prediction of the total stem volume when compared to the existing stem volume model and with a simple volume model. It is concluded that the compatible taper and stem volume equations are more convenient to use and therefore it is recommended to be applied in the Larix kaempferi species of South Korea.
