  • This study evaluated the perception, school stress, psychological factors, and association of students in middle and high school groups in terms of their BMI (Body Mass Index). The '2010 Korea Youth Health Survey 'was used to study data 7187 people. The subjects were classified into the underweight group (BMI < 20), normal group (BMI 20 - 24), overweight group (BMI of 25-29), and obese group (BMI of 30 or higher). The subjects found to have experienced smoking were as follows: underweight BMI group (17.2%), normal weight group (18.4%), overweight group (21.8%), and obese group (25.8%) (p=0.016). The level of satisfaction was as follows: $14.24{\pm}3.15$ for the normal weight group, $13.67{\pm}3.13$ for the overweight, and $12.84{\pm}3.72$ in the obese group. The normal-weight group had a higher level of satisfaction (p=0.005). Underweight, normal, overweight, and obese BMI group were at school for an average of $33.57{\pm}5.76$, $33.45{\pm}5.50$, $33.12{\pm}5.34$, and $32.21{\pm}7.43$ hours per week, respectively (p=0.044). Therefore, the development of social misfit youths needs to be managed properly and effectively to improve their physical and mental health. Industry, academia and government need to collaborate with programs to achieve this aim.

  • B-cell-specific Moloney murine leukemia virus integration site 1 (Bmi1) is a polycomb group protein and a core component of polycomb repressive complex 1. Initial research into Bmi1 has focused on its role in tumorigenesis, and it is generally accepted that it is important for the proliferation and survival of cancer cells. However, more recent studies have revealed that Bmi1 is downregulated in brains with neurodegenerative disease and that it regulates the function of mitochondria and reactive oxygen species levels. In this study, we tested the therapeutic potential of Bmi1 in pilocarpine-induced seizures in Bmi1-knockout mice. Bmi1 expression transiently increased in the hippocampal CA1 and CA3 and the dentate gyrus following pilocarpine-induced status epilepticus (SE). In terms of seizure behavior, SE induction was 43.14% and 53.57% for Bmi1+/+ and Bmi1+/- mice, respectively. However, there was no significant difference in mortality or hippocampal damage between the two groups. Two months after SE induction, the frequency of epileptic seizures in the Bmi1+/- mice was 50% lower than in the control group, although the difference was not statistically significant. In addition, mossy fiber outgrowth in the Bmi1+/- mice was significantly higher than in their wild-type littermates. Taken together, these data indicate that reduced Bmi1 activity increases pilocarpine-induced seizure probability and mossy fiber outgrowth.

  • The purpose of this study was to investigate the snack and beverage intake patterns of students by body mass index groups (BMI <18.5, 18.5-23, 23-30, ${\geq}$30). Questionnaires were completed by 1381 high school students in Seoul, Incheon, and Gyeonggi-do, the area of Korea's capital region. There were no significant differences in skipping meals for overweight (BMI 23-30 and ${\geq}$30) or under-nourished (BMI <18.5) students. Girls skipped dinner more frequently than boys. Boys and girls both preferred meat and disliked fish regardless of BMI. Girls with BMI 23-30 disliked vegetables. Boys and girls would rather have crackers, candies, and chocolates than potatoes as snacks regardless of BMI. Obese boys (BMI ${\geq}$30) preferred flour-based food, fast food, and other food as snacks. Girls liked fruits more than boys. Snacks were eaten 2-3 times per week, when students were hungry or bored. There were no significant differences in the frequency or reasons (habitual, stressed) for snack consumption by BMI. Girls liked juice more than boys did, and boys preferred soda water more than girls did. Both the under-nourished (BMI <18.5) boy and girl groups had more juice than the overweight (BMI 23-30 and ${\geq}$30) groups. Obese (BMI ${\geq}$30) boys did not more drink soda water than other BMI groups. The under-nourished (BMI <18.5) boy group had more soda water than the normal (BMI 18.5-23) and overweight (BMI 23-30) groups. Girls in the overweight (BMI 23-30) group had 2 more cups of soda water a day than the normal group (BMI 18.5-23). Therefore, skipping meals and beverage intake patterns might influence BMI.

  • The purpose of this study was to find out how diagnosis of hyperlipemia differed for according to BMI and %Fat. The included subjects were 224 adult women, they performed physical measurement and BMI measured %Fat by BIA. Blood pressure and lipid profiles were measured in the NPO state. The LDL calculated in using a formula of Friedwald and an atherogenic index was calculated using the serum TC lever divided by th HDL level As a results, HDL decreases so that BMI and %Fat increase and TC, TG, LDL, AI appeared by increasing. There was significant correlation(r=.585) between BMI and %Fat, and lipid profile correlation with BMI is higher than %Fat. In conclusion, diagnosis results of hyperlipemia according to BMI and %Fat could become different conclusively. In study it seems that BMI's diagnosis ability on hyperlipemia is high but the most desirable method uses BMI and %Fat together and evaluates lipid profile.

  • In this work, we prepared epoxy/BMI composites by using N,N'-bismaleimide-4,4'-diphenylmethane (BMI), epoxy resin (diglycidyl ether of bisphenol-A (DGEBA)), and 4,4'-diamino diphenyl methane (DDM). The thermal properties and water sorption behaviors of the epoxy and BMI composites were investigated. For the epoxy/BMI composites, the glass transition and decomposition temperatures both increased with increasing BMI addition, which indicates the effect of BMI addition on improved thermal stability. The water sorption behaviors were gravi-metrically measured as a function of humidity, temperature, and composition. The diffusion coefficient and water uptake decreased and the activation energy for water diffusion increased with increasing BMI content, indicating that the water sorption in epoxy resin, which causes reliability problems in electronic devices, can be diminished by BMI addition. The water sorption behaviors in the epoxy/BMI composites were interpreted in terms of their chemical and morphological structures.

  • This study was conducted to investigate dietary macronutrient and $VO_{2}$ by BMI The subjects consisted of 50 female college students. They were divided into three groups: Below BMI 18.5 kg/$m^{2}$ (n = 9), BMI 18.5 - 23 kg/$m^{2}$ (n = 28), above BMI 23 g/$m^{2}$ (n = 13). Health-related questionnaires, dietary macronutrients, macronutrient compositions, food frequency questionnaires, body compositions and $VO_{2}$ were studied. Macronutrient compositions that macronutrient intakes were expressed by the percentage of daily energy intakes. There were significant differences in body fat, percent of body fat, and fat distribution by BMI Also, significantly increasing of basal metabolic rate (BMR) was shown by BMI, but BMR per body weight was decreased by BMI Overall, there were no significant differences in health-related questionnaires, food frequency questionnaires (FFQ), dietary macronutrients and $VO_{2}$ by BMI but salty taste preferences and carbohydrate intakes, FFQ of beans, white vegetables rand, yellow-green vegetables in the above BMI 23 g/$m^{2}$ group were significantly higher than other groups. There were no significant differences in macronutrient composition but the lipid composition of subjects was shown above $20\%$. Also, energy intakes of subjects were shown to be low; especially the below BMI 18.5 kg/$m^{2}$ group was very low ($55\%$ of RDA). Significantly positive correlation was found in BMR and body composition such as skeletal muscle & lean body mass, but significant correlation was not found in BMR and dietary macronutrients. Overall, researched energy metabolism factor was not different by BMI Only in the BMI 18.5 23 kg/$m^{2}$ (normal) group, significantly positive correlation was found in $VO_{2}$peak and body fat oxidation. Therefore, proper nutritional education for female college students is needed in order to improve their obesity-related health. Moreover, a nutritional survey method of finding diverse factors that affect their health should be developed to meet various needs.

  • Purpose: Overweight can be defined by the body mass index (BMI) and is likely associated with an increased cardiovascular disease risk. However, waist circumference (WC), a central adiposity index, may be a better indicator of cardiovascular disease risk. Studies comparing the effects of BMI and WC on cardiovascular risk factors, such as high blood pressure (BP), are rare in adolescents. Methods: We analyzed the correlations of BMI and WC with BP in 3,363 Korean adolescents (aged 10-19 years), using data from the Korean National Health and Nutrition Examination Surveys (2009-2011). Results: Systolic BP (SBP) in both sexes and diastolic BP (DBP) in boys were higher in the high BMI (>85th percentile) and high WC (>90th percentile) groups. High BMI and high WC were positively correlated with high SBP (>90th percentile) in both sexes, and high DBP (>90th percentile), in boys. BMI maintained its positive associations with SBP, DBP, high SBP, and high DBP in the normal weight ($BMI{\leq}85th$ percentile) and overweight (BMI>85th percentile) groups in both boys and girls, as well as in all subjects of both sexes, even after adjustment for WC. However, WC did not correlate with SBP, DBP, high SBP, or high DBP after adjustment for BMI in any group in either sex. Conclusion: In Korean adolescents, BMI correlated better with BP and high BP levels than WC. Further, BMI was positively associated with BP and high BP in the normal weight group as well as in the overweight group.

  • BMI nozzles in bottom head of the nuclear vessel are one of major components in nuclear power plants. The BMI nozzles have high possibility to generate PWSCC(primary water stress corrosion crack) according to recent foreign case although operation temperature is lower then the upper head of the nuclear vessel. Thus, nondestructive inspection of the BMI nozzles is required. But, inspection of BMI nozzles is not easy since the BMI nozzles placed in high radiated area and inside the nozzles filled with boric acid. Thus, in this study, a TOFD transducer for inspection of BMI and automated scanner system with water were developed. Also, validation of performance of the developed transducer and system are performed using specimens with artificial defects.
