The purpose of this study was to determine the correlation between young children's picky eating behavior and mother's attitudes, beliefs and practices regarding the eating habits of children. Using a sample of 304 mothers of four or five year-old children, confirmatory factor analysis was conducted to test a 7 factor model, which included mother's beliefs and practices related to the feeding of their children. Following this, a t-test was conducted to examine the differences between the feeding behaviors of mothers of both of picky and non-oicky eaters, respectively. The results indicated that picky eater's eating behaviors were positively related to the pressures exerted by mothers and negatively related to the mother's concerns about their child's weight and child's BMI. These findings suggest that the pressures mothers exert upon their children to eat, their child's weight and picky eating behaviors are correlated to each other.

The Kimchi intake of elementary students in both school and home is decreasing due to their westernized eating habits which have been affected by the rapid economic growth and industrialization in our modem society. The purposes of this study were to examine the influence of menu selections on the Kimchi intake rate and to provide basic data for an appropriate Kimchi serving size to reduce the plate-waste rate. The results showed that the average daily intake rate of Kimchi of low-grade students was 58.2%, equating to 6${\sim}$18 g, compared to 64.6% for high-grade students, equivalent to 13${\sim}$24 g. Correlation analysis of the intake rate of menu items and Kimchi showed that the Kimchi intake rate increased with increasing total meal intake rate, rice intake rate, soup intake rate, rice mixed with grains intake rate, clear soup intake rate and soybean-paste soup intake rate, but that it decreased as the intake rate of seasoned uncooked vegetables of high-grade students increased. This study is expected to be utilized as a solution to increase the Kimchi intake rate of elementary school students, and also to determine the proper serving size per person on the menu items by grade.

Modern society has been experiencing by population growth and urbanization that bring, a change of eating habits which has occurred a various types of waste in a large amount. Even though these wastes are required an immediate treatment with difficulties unsanitary handling and existing waste treatment method are by incineration, fermentation, drying and etc. however a bad smell occurs after the treatment that need's a lot of energy in processing organic wastes with high moisture contents and wasteful and inefficient problem. The strength assessment of the organic waste agitating vessel is required in terms of safety due to the differences of loading on the shaft that was treated by agitating the mixture of food waste. The damage of agitating axis is depended on steam pressure, temperature condition and the force moment that exerted by the food waste. Thus the strength assessment and stability evaluation are very important, especially to handle a hard waste. In this study the rotation capacity of agitation is about 5 tons considering general structural rolled steel pressure vessel strength and steam pressure. The purpose is to estimate the safety and strength evaluation for a agitator axis and impellers according to the rotating angle of the axis under the condition of the 3.2 ton capacity reactor.

This study was conducted with 20 female gymnasts and 23 age-matched controls to examine pattern, weight control behavior and nutritional status. Most gymnasts(95.0%) reported that they used weight-control methods, while relatively few age-matched controls employed these methods. These methods included sauna(95.0%), food restriction(90.0%), excess exercise (70.0%), laxative abuse(10%) and use of diet pills(10%). Gymnasts had significantly (p<0.05) lower scores for statements related to 'sneaking food', 'vomiting after overeating', showing more negative eating behavior than age-matched controls. Energy intake of gymnasts was 968.9$\pm$421.4kcal while energy expenditure was 2,091$\pm$361kcal, showing negative evergy balance(-1,1225$\pm$534.6kcal). Female gymnasts consumed less than 70% of the RDA for protein, calcium, iron, vitamin A, thiamin, riboflavin and niacin, which reflects their low energy intake. The average intakes of calcium, iron, vitamin A, thiamin, riboflavin and niacin did not meet the recommended dietary allowances for their age groups. Adolescent athletes who train vigorously and consume a low-energy diet may be exposed to an increase in potential health risks. Therefore, individuals who advise athletic adolescents regarding training and dietary habits need to emphasize the importance of consuming an appropriate energy intake to support performance as well as growth and development. The sports nutritionist is in a position to convey such information to coaches, physicians, parents and to the athletes themselves.

Although they generally undergo less change in somatotype than other age groups, women in their early twenties have postural changes incurred with their inappropriate postures during the growth period. Since such somatotype changes reduce their satisfaction in the fitting of ready-made clothing, the study intends to examine the inadequate postures and life habits of women in their twenties and to analyze their self-recognition and actual conditions of the bad fit of ready-made clothes. A survey questionnaire was conducted on 225 customers and 29 sellers of ready-made clothes. According to the result, it was found that their inappropriate postures had made their back and shoulders undesirably bent and led to their low satisfaction in the fitting of ready-made clothes. Therefore, it is necessary to perform researches for developing renovated design in consideration of their somatotype changes.

This study was conducted to investigate the relationships between yearly variations of elimatic elements and yearly variations of productivity in potato. In addition, correlation coefficients among yield and yield components were estimated. The data of yield and yield components were investigated for 9 years from 1987 to 1995. The meteorological data what gathered at the Goheung Weather Station for the same period of crop growing season were used to find out the relationships between climatic elements and crop productivity. Yearly variation of the daily minimum temperature in March and April were large with coefficients of variation (C.V.) of 126.0%, 368%, respectively, but the variation of the daily mean and maximum temperature in May and June were relative small. Stem length and number of stem show more C.V. of 9.3%, 14.3%, respectively, but the variation of the yield was relative small with 3.7%. Correlation coefficients between the amount of precipitation in April and yield, yield and daily mean temperature in June were negatively significant at the level of 5, 1 %, respectively. Correlation coefficients between the growth habits and yield are positively significant at the level of 5, 1 %, respectively. Simple linear regression equations by the least square method are estimated for stem length (Yl) and the precipitation in April(X) as Y,=82.47-0.11x (R2=0.3959), and for yield(Y2) and the precipitation in April(X) as Y,=2003.61-0.94X (R2=0.5418).

Purpose: Adolescence is a developmental period characterized by the rapid growth of the musculoskeletal system, which is important for maintaining correct posture. Incorrect posture, lack of exercise, and reduced physical activity can cause spine deformities and affect lifelong health. This study was designed to evaluate the application and effect of a program for improving adolescents' musculoskeletal health. Methods: A quasi-experimental pilot study was conducted with 13 male and 20 female middle and high school students, with an average age of 15.39 years. Their general characteristics and physical measurements were obtained. The program consisted of group exercises (60 minutes, once per week), gait pattern monitoring, and online communication. A paired t-test and Wilcoxon signed-rank test were used to examine the program's effect. Results: Overall posture habits improved, and the total musculoskeletal index decreased; however, these results were not statistically significant. Conclusions: The devised program was effective in improving musculoskeletal imbalance. Therefore, effective programs and health devices should be developed to help adolescents maintain correct posture and encourage and support continuous participation in such programs.

Objectives: Young children's feeding characteristics can play an important role in eating habits and health during later childhood. This study was conducted to examine the associations of feeding characteristics with dietary patterns and obesity in children. Methods: This study utilized data from the Korea National Health and Nutrition Examination Survey conducted between 2013 and 2017. In total, 802 toddlers were included, with information on their demographic characteristics, feeding practices and duration, and 24-hour recall obtained from their parents. Feeding characteristics were categorized into feeding type, duration of total breastfeeding, duration of total formula feeding, duration of exclusive breastfeeding, and age when starting formula feeding. Dietary patterns were identified based on factor loadings for the food groups for 3 major factors, with "vegetables & traditional," "fish & carbohydrates," and "sweet & fat" patterns. Overweight/obesity was defined as ≥85th percentile in body mass index based on the 2017 Korean National Growth charts for children and adolescents. Multiple regression analysis was conducted to examine associations between feeding characteristics and dietary patterns. The association between dietary patterns and obesity was analyzed using multivariable logistic regression analysis. Results: The early introduction of formula feeding was inversely associated with the "vegetables & traditional" pattern (β=-0.18; 95% confidence interval [CI], -0.34 to -0.02). A higher "vegetables & traditional" intake was associated with a lower risk of obesity (odds ratio, 0.48; 95% CI, 0.24 to 0.95). Conclusions: Feeding characteristics are associated with dietary patterns in later childhood, and dietary patterns were shown to have a potential protective association against obesity.

The domestic artificially sweetened beverage market has grown rapidly in recent years, and sodas have led this growth. This study investigated consumer food purchasing behavior of artificially sweetened sodas in terms of the food health stereotypes of "vice" and "virtue"; used to denote unhealthy and healthy food purchases, respectively. The study was conducted using consumer panel data collected by the Rural Development Administration from 2017 to 2020. Given the semi-continuous nature of artificially sweetened soda purchases, Cragg's two-part model was used for the analysis. The probability of purchasing artificially sweetened sodas increased as expenditure on snacks (a vice food category) increased. However, of those panelists who purchased artificially sweetened sodas, expenditure on artificially sweetened sodas decreased with expenditure on snacks and increased with expenditure on fruits (a virtue food category). These results suggest that vicious-lifestyle consumers choose artificially sweetened sodas when they regulate eating habits, whereas virtuous-lifestyle consumers increase artificially sweetened soda expenditure for hedonic consumption to reduce guilt based on a sensible trade-off effect.
