The association between heavy metals in the blood and obesity has been examined in many studies. However, inconsistencies have been observed in the results from these studies. The present study was conducted using data from 119,181 participants of the Korea National Health and Nutrition Examination Survey (KNHANES) for 11 years in 2005 and between 2008 and 2017. The subjects with missing heavy metal blood tests, health interview data, and health examination data were excluded from the study. The study population comprised 1,844 individuals (972 men, 872 women) who were eligible for inclusion. It was found that obesity and abdominal obesity were associated with an increase in both blood mercury (P<0.001) and alanine aminotransferase (ALT) (P<0.001). After adjusting the confounding factors, those with concurrent high levels of ALT and the highest tertile of mercury showed an increased risk of obesity (odds ratio 4.46, 95%, confidence interval 2.23~8.90, P<0.001) as well as abdominal obesity (odds ratio 5.36, 95%, confidence interval 2.57~11.17, P<0.001). The interrelationship of mercury and ALT with the parameters of body mass index (P for interaction=0.009) and waist circumference (P for interaction=0.012), respectively, have been observed to be significant, suggesting that the reciprocal relationship could contribute to obesity and abdominal obesity.

The purpose of this study was to compare core muscle activity and thickness in the abdomen (internal Oblique, IO; External Oblique, EO; Transverse Abdominis, TrA) according to walking training methods. Tests were performed on 20 healthy men who randomly assigned to two groups, divided by Nordic walking (n=10) or Power walking group (n=10). They were performed Nordic walking or Power walking training for 2 weeks that is consistent with each of the assigned groups. Results demonstrated that Nordic walking was more effective than Power walking in improving IO and EO activities. Nordic walking is believed to be useful method for a variety of therapeutic exercise as a stable balance with the stick in addition to normal gait and trunk stability.

The Golden ratio which was started to be use by Eudoxos, Greek mathematician, is being used as a tool to explain beauty in various fields like architecture, art, society, nature and so on. In addition, people not only use the golden ratio, also use obesity to consider a standard of beauty. This study's subjects are students of H university. We researched their Golden ratios of their whole body, upper body and lower body. Also, to research their obesity levels, we used Obesity degree, Waist-hip ratio and Percent body fat. According to different features of the subjects, we study differences between the golden ratio and obesity and how the golden ratio of body affects obesity.

In this study, we investigated whether the combined administration of berberine (BBR) and silibinin (SBN) was effective in improving hyperlipidemia and anti-obesity efficacy using a high-fat diet (HFD)-fed obese mouse model. HFD-induced obese mice were supplemented with the BBR and SBN combination (BBR-SBN) along with the HFD administration for 8 weeks. During the experiment, body weight, food intake, and levels of total cholesterol, triglyceride and high-density lipoprotein (HDL)-cholesterol were analyzed. Consumption of HFD in the mice caused rapid increases in body weight and the levels of total cholesterol and triglycerides compared to the normal control (NC) group. However, supplementation of BBR-SBN in these obese mice significantly reduced body weight gain and suppressed the levels of total cholesterol and triglyceride with the increment of HDL cholesterol level. In the HFD-fed group, abdominal fat weight was significantly increased and the adipocytes within the epididymal adipose tissue were found to have expanded sizes compared to the NC group. However, in the BBR-SBN group, the sizes of the adipocytes were comparable to those of the NC group and abdominal fat weight was significantly reduced. Moreover, the deposition of giant vesicular fat cells in liver tissues seen in the HFD-fed group was considerably reduced in the BBR-SBN group. These results suggest that the BBR-SBN combination tends to have synergic potential as an anti-obesity agent by significantly reducing body weight gain as well as lowering serum lipid levels and thus improving anti-obesity efficacy in HFD-induced obese mice.

Objectives: This study was conducted to analyze the effects of obesity and abdominal obesity in accordance with the elderly's food consumption frequency and patterns. Methods: The source of this study was based on raw data from the fifth Korea National Health and Nutrition Examination Survey (KNHANES V-1, V-2, V-3). The subjects of the elderly aged 65 and over 5742 people were in the final analysis. Results: The results of the study showed that the elderly's obesity and abdominal obesity were significantly affected by their sex, food consumption frequency, smoking, and spouses. Moreover, subjects without dinner consumption had 0.658 times lower possibilities of obesity. In addition, consumption of three meals a day will be obesity 0.771 times lower than that of one or two meals a day(OR=0.771, 95%CI=0.65-0.913). Conclusions: The goal of this study is to achieve a better understanding of the characteristics of obesity depending on the elderly's eating habits and finally to present the baseline data for the improvement of their dietary habits.

This study was conducted to identify the factors affecting sarcopenia in middle-aged and older women in Korea. This is a cross sectional study by using 5th Korea National Health and Nutrition Examination Survey data. The data were analyzed by using the SPSS 26.0 program. The prevalence of sarcopenia was 10.8%. There were significant differences according to ASM, age, education, current job, marital status, perceived health status, energy intake, protein intake, BMI, body fat, alcohol drinking, menopause, central obesity, impaired fasting glucose and chronic disease. Woman with central obesity and osteoarthritis increased risk of sarcopenia each 4.15 times(p<.001), 3.06 times(p=.041) and energy intake decreased risk of sarcopenia 0.99 times(p=.043). In order to prevent and manage sarcopenia, strategies for managing central obesity and osteoarthritis in mddile-aged and older woman and adequate food intake are needed.

In this paper, a series of numerical analyses were performed to evaluate the flexural resistance of steel plate girder with longitudinally stiffened and slender web. The SM490 steel was adopted for the study and the flexural resistances evaluated from the numerical analysis were compared with those suggested by the AASHTO LRFD and the Eurocode 3 codes, respectively. It was found that the AASHTO LRFD code could considerably underestimate the flexural resistance as the web slenderness becomes smaller. This comes from the fact that current AASHTO LRFD code does not consider a possible increase of slenderness limits for compact and noncompct web, and also an additional effect of web restraint on the rotation of compression flange in longitudinally stiffened web. Therefore, the slenderness limits of web and flange have been newly proposed for the plate girders with longitudinally stiffened web and it is analytically verified that the flexural resistance can be appropriately estimated by applying the proposed slenderness limits to the AASHTO LRFD code.

The purpose of this study is to investigate the effect of abdominal massage, on abdominal bloating and the recovery of bowel movement after sleep colonoscopy. The study design is the time difference before and after the non-equality control. The subjects were 22 patients each in experimental group and control group who recieved sleep colonoscopy at the G hospital in C city, The data collection period was from June 1, 2018 to August 25, 2018, and the control group's data were first collected with time difference from the collection of experimental group's data to prevent the spread of the experiment. Data were analyzed using IBM SPSS 24.0 and tested by independent sample t-test, $x^2-test$ and Fisher's exact probability test to verify the homogeneity of general characteristics of the subjects. Shapiro-Wilk was used to verify the normality of the abdominal circumference changes in the experimental and control groups. Mann-Whitney U test was used to verify the pre-homogeneity of the abdominal circumference of the subjects. The experimental results were verified by Fisher's exact probability test, Friedman test and Mann-Whitney U test. These results suggest that the abdominal massage can be used as a nursing intervention after sleep colonoscopy by reducing the gas discharge time($x^2=19.75$, p<.001) and abdominal bloating($x^2=29.93$, p<.001).
