The purpose of this study is to examine the relationships between body mass index (BMI), satisfaction of perceived somatotype, and eating disorder of 133 female college students from Gyeong-gi province. The average weight is $55.3{\pm}8.8kg$, and the BMI is categorized into three groups: underweight, normal weight, and overweight. In terms of the satisfaction for perceived somatotype, 58.6% of the total respondents replied "unsatisfied," which consists of 14% of the underweight group, 37.6% of the normal weight group, and 6.8% of the overweight group. This reveals that the negative association between the satisfaction levels of perceived somatotype and BMI in the normal weight group is statistically significant (p<0.001). Among three eating disorder scores, the first factor, the drive for thinness, shows significant difference (p<0.005) among groups with 2.82 points in the underweight group, 3.38 points in the normal weight group, and 3.86 points in the overweight group; such result shows that there is a drive for being skinny even within the underweight group. Second, the satisfaction levels of perceived somatotype type shows significant dissatisfaction among all groups with 3.41 points in the underweight group, 4.15 points in the normal weight group and 4.73 points in the overweight group. Third, the bulimia degree reveals a significant difference within each group, 2.15 points in the underweight group, 2.33 points in the normal weight group, and 2.78 points in the overweight group. Overall, more than half of the female college students are dissatisfied with their body shapes despite the fact that they are under or within the normal weight. In addition, the drive for being skinny and dissatisfaction levels of perceived somatotypes appear to be significantly higher with higher BMI levels.

BACKGROUND/OBJECTIVES: Although children of ethnic minority groups are experiencing a transition from a predominance of undernutrition to overnutrition, there is little evidence of a dual-malnutrition burden. Therefore, this study examined the double burden of malnutrition among school-aged ethnic minority children living in mountainous areas and its association with their diets. SUBJECTS/METHODS: A cross-sectional study was conducted from September 2019 to March 2020 in 3 mountainous areas of Northern Vietnam among 1,556 ethnic minority school-aged children. The prevalence of under-nutrition (stunting and thinness) and over-nutrition (overweight and obesity) were measured using the WHO 2006 child growth standards (height-for-age and BMI-for-age Z-score). Nutritional practices were evaluated by the frequency of food consumption based on a 4-level scale. RESULTS: The percentage of children with stunting and thinness were 14.0% and 5.4%, respectively, while the figure for overweight/obesity was 9.4%. The factors positively associated with stunting were living in a family with more than 2 children or being Muong/other ethnicities compared to the Tay ethnicity. Children who consumed fish/shrimps/crabs or milk weekly/daily were less likely to be undernourished compared to those who never consumed these foods. By contrast, children who never consumed foods rich in vitamin A precursors and vitamin A and fruit or consumed daily snacks/junk food were more likely to be overweight/obese. CONCLUSIONS: Undernutrition remains a common issue among school-aged children and adolescents of ethnic minority groups, while over-nutrition exists simultaneously. Public health nutrition programs promoting adequate diets and positive lifestyle changes related to nutrition are essential to tackle the double burden of malnutrition among ethnic minority children.

This study presents development of a automatic design software for process and die design of hot extrusion of aluminium alloys through square dies. The design of extrusion dies is still an art rather than a science with increasing complexity of shape and thinness of section. Therefore, most of the die design is still dependent on personal judgement, intuition and experience. The objective of this study is to develop a software system which includes a design rule extracted from literatures and experts in the extrusion industry. The developed system is effectively used to design extrusion processes and dies with reduced lead time and trial extrusion.

This paper provides review of research results undertaken on reinforced concrete wall panels in one way and two way. The review also highlights two well accepted code design methods from the American (ACI) and Australia Concrete structures standards. The emphasis is on walls under axial compression only with changes in various parameters. These include the variation of panel dimensions panels (ie. Slenderness, thinness and aspect ratios), steel reinforcement, eccentricities, concrete strength and support conditions. The main purpose of this review is to compile research previous by undertaken to highlight the inadequate in certain research literature. It is envisage that this review will expose areas in wall research required so that inadequate in current methods can be rectified.

Recently, the customer's demands for automotive steel sheet have been diversified and sterned more. Therefore, as the tendency of auto industry light-weight, one among these requirements is the trend for high strength together with the thinness of automotive steel sheet. Because Mn added essentially in producing high strength steel sheet is bonded strongly with oxygen, the Fine oxidation layer was created at the welding face after the flash butt welding operated in entry section of pickling line. Thereby it was caused the crack or breakage of welding part in process of cold rolling. At this research, in order to protect the contact Mn with oxygen in atomosphere it was considered to fire oxygen with LNG and the related researches have been gone forward with the find out concrete and to apply them to operation.

Recently 'lookism' is prevalent in Korean society. Lookism is a thought that one of causes of unequality of the mankinds is the appearance. The appearance is not only endowed but is made by efforts. Korean market related beauty including cosmetics occupied over $15billion. The purpose of this study is to find the determinants of the appearance management behaviors. Considering social characteristics of Korea and previous literatures, Collectivism, body image were chosen as an explaining variables. And self-esteem, attitudes toward sex roles and the shopping orientation and some demographic variables were selected. For the data analysis, 514 questionnaire for male and female in Daegu were collected. The determinants of appearance management behaviors were perceived level of living, concerns toward thinness, shopping orientation, appearance evaluation, female, family oriented thinking, belief in appearance power, attitude toward sex roles.

The design of extrusion dies is still an art rathere than a science with increasing complexity of shape and thinness of section. Therefore, most of the die design is still dependent on personal judgement, intuition and experience. The objective of this study is to develop an expert system which includes a rule base system extracted from literatures and experts in the extrusion industry. The system also includes finite element simulation program. The developed system is effectively used to design two types of processes and dies with lead time and trial extrusion.
