This study was conducted via survey of 300 enrolled male and female high school students in the Chungnam area. The survey focused on students' dietary habits, changes in dietary habits based on the school lunch menu, and satisfaction of school lunches, in order to identify new methods for changing dietary habits and improving satisfaction of school lunches. Regarding the general characteristics of those surveyed, most were 17 years old, and of the same gender. Ninety-nine percent of those surveyed lived in farming areas, and the majority of students' parents graduated from high school and are self-employed. Research on dietary habits according to gender found that male students ate more regularly than did female students, with a difference of (p<0.001) between the two genders. Regarding the degree of which students ate only what they want, differences of (p<0.05) were found between the genders. The types of snacks frequently consumed were found to be flour-based snacks for the male students, whereas the females mostly consumed sweet foods and bread snacks. Research on satisfaction of school lunches according to gender also showed a difference of (p<0.5). Specifically, 48.7% of male students responded 'average', whereas only 45.3% of female students responded in the same way. The reason for dissatisfaction of school lunches were quality and nutrition for the male students (30%) and taste for the female students (60.4%), with a significant difference according to gender (p<0.05). Regarding the types of food most left over, both female and male students answered fish, bean curd, and soy products.
The purpose of this study was to investigate dietary behavior relative to personality type in young adults, and to offer basic data to apply during nutrition education and counseling. A total of 166 university students performed the MBTI (Mayers-Briggs Type Indicator) test along with questionnaire interviews, and 3 day 24-hr dietary recalls. MBTI personality preferences are presented and separated by 4 types of indices: Extraversion (E) and Introversion (I), Sensing (S) and Intuition (N), Thinking (T) and Feeling (F), and Judgement (J) and Perception (P). More subjects in the I type than the E type had lunch everyday or ate out more than once a week. Compared to the P type, the J type ate a higher proportion of meals with family, and seldom drank alcohol, but a lower proportion had a preference for salty taste. Compared to the N type, the S type had a higher proportion of subjects who consumed large quantities at regular meals as well as when under high amounts of stress. Also, the S type subjects had significantly higher lipid intakes than the N type subjects. Compared to the F type, a higher proportion of the T type subjects ate meals alone but a lower proportion had a dislike for bitter tasting foods. There were no significant differences in total food or energy intakes relative to the different personality types. In conclusion, individual personality type may influence dietary behavior, but additional studies are needed that contain individuals of various ages and include long term dietary surveys.

This study was undertaken to investigate the causal perceptions and health seeking behaviors of Rheumatoid arthritis patients, define and understand the typology, and find the relationship between causal perceptions and health seeking behavioral types. There were six types(Physical Fatigue, Dispensation of Nature, Causality to Environment, Conscience of Guilty, Rationally perceiving, Psychological Stress) of subjective opinion about Causal Perceptions of Rheumatoid Arthritis Patients. And there were four types(Oriental medical Treatment, Information Seeking, Dietary Control. Western Medical Treatment) of subjective opinion about Health Seeking Behaviors. In the relationship between types of the causal perceptions and health seeking behaviors, oriental medical treatment and information seeking type were common health seeking behaviors of all six causal perception types. Only difference for internal causal perception types was related to hospital instructions and external causal perception types were related to dietary control. The result of this study can help health care providers, especially nurses to understand the types of causal perceptions and health seeking behaviors of Rheumatoid arthritis patients to gain treatment compliance from patients according to their causal perceptions of the illness, and use it to develop educational nursing intervention to aid health care.
This study was done to investigate the nutrient intakes and plasma biochemcial indices in 68 female college students according to their skin types. Nutrient intakes were investigated by quick estimation. The plasma TG and total cholesterol levels were measured by the Spotchem sp-4410. The plasma levels of retinol and $\alpha$-tocopherol were measured by HPLC. In addition, the activities of antioxidant defense enzymes such as plasma glutathione peroxidase(GSH-Px) and glutathione reductase(GHS-Rd) were determined. All data were statistically analyzed by SAS PC package program. The results of this study were as follows : The average age, height, weight, BMI, systolic blood pressure and diastolic blood pressure ofthe subjects were $20.9{\pm}1.9yr, 160.7{\pm}4.3cm, 53.0{\pm}7.1kg, 20.5{\pm}2.4kg/m^2, 105.3{\pm}11.5mmHg and 70.6{\pm}7.7mmHg$, respectively. Ten students(14.7%) had normal skin type, 19 students(27.9%) had dry skin type, 11 students(16.2%) had oily skin type, 17 students(25.0%) had acne and 11 students(16.2%) had mixed skin type. The intakes of energy and fats in oily skin group were significantly higher(p<0.05) than those of the dry skin group, but vitamin C intake in the mixed skin group was significantly higher(p<0.05) than those of the dry skin group, but vitamin C intake in the mixed skin group was significantly lower(p<0.05) than that in other skin types. The intakes of other nutrients were not significantly different among skin types. The analysis of lipids showed that the plasma total-cholesterol level of mixed skin group was significantly lower(p<0.05) than that of the oily skin group, whereas other lipid levels were not significantly different. The other parameters such as retinol, $\alpha$-tocopherol, GSH-Px and GSH-Rd of plasma were not significantly different among skin types. Overall results indicate that dietary intake pattern may influence skin type and thereby some blood biochemical indices can be different by skin types.
This study examined the current status of caution labels on cooking utensils made from plastics or glass, toward suggesting improvements in labeling for consumer's safe use. Distributors were categorized into four types, plastic kitchen utensils were categorized into seven types according to usage, and glass kitchen utensils were categorized into two types. Generally, the percentage of cooking utensils made from plastics or glass that have caution labels were not high. For the types of labels on cooking utensils made from plastic and glass, stickers were the most frequently used, and of these, a high percentage scored "fair" in label perception. On the basis of these results, regulations are needed to strengthen caution labels for kitchen utensils.

To investigate the effects of different type of dietary fat on survival metabolism of fasting rats, one group rats (FO) were fasted, another one group rats (BM) were fed normal diet and the others were fed only one of the following fat diets: beef tallow (FT), corn oil (FC), and perilla oil (FP) of 11.4g/kg respectively. Most FO group rats survived for 6 days and large part of the only-fat-diet groups rats survived for 16 days. Body weights of all rats in fasting and only-fat-groups, measured just one day prior to death owing to fasting or caloric malnutrition, decreased by 24.5%~25% only-fat to fasting rat somewhat extended the survival time but the specific properties of dietary fat types had no remarkably differential effect on survival time and body weight gain rate. The features of liver and kidney weight gain rate of all rats in fasting and only-fat-diet groups were similar to those of body weight gain rate. In FO groups blood levels of total-cholesterol, triglyceride, and glucose markedly reduced whereas GPT activities and BUN levels considerably increased as compared to BM group. However the types of dietary fat perse did not affect blood total cholesterol, triglyceride, glucose, BUN levels, and GPT activities in early stage of fasting in FC and FP group. GPT activities in rats of FP group just prior to death of starvation seemed to be affected by the dietary fat types. The results showed that only-fat-feeding to fasting rats somewhat extended survival time but the types of dietary fat had no remarkably differential effect on survival time and metabolism of fasting rats.
Objective: The objectives were to investigate correlations between energy digestibility (digestible energy [DE]:gross energy [GE]) and various fiber types including crude fiber (CF), total dietary fiber (TDF), soluble dietary fiber (SDF), insoluble dietary fiber (IDF), neutral detergent fiber (NDF), and acid detergent fiber (ADF), and to develop prediction equations for estimating DE in feed ingredients and diets for growing pigs. Methods: A total of 289 data with DE values and chemical composition of feeds from 39 studies were used to develop prediction equations for DE. The equations were validated using values provided by the National Research Council. Results: The DE values in feed ingredients ranged from 2,011 to 4,590 kcal/kg dry matter (DM) and those in diets ranged from 2,801 to 4,203 kcal/kg DM. In feed ingredients, DE:GE was negatively correlated (p<0.001) with NDF (r = -0.84), IDF (r = -0.83), TDF (r = -0.82), ADF (r = -0.78), and CF (r = -0.72). A best-fitting model for DE (kcal/kg) in feed ingredients was: 1,356 + (0.704 × GE, kcal/kg) - (60.3 × ash, %) - (27.7 × NDF, %) with R2 = 0.80 and p<0.001. In diets, DE:GE was negatively correlated (p<0.01) with NDF (r = -0.72), IDF (r = -0.61), TDF (r = -0.52), CF (r = -0.45), and ADF (r = -0.34). A best-fitting model for DE (kcal/kg) in diets was: 1,551 + (0.606 × GE, kcal/kg) - (22.1 × ash, %) - (25.6 × NDF, %) with R2 = 0.62 and p<0.001. All variables are expressed as DM basis. The equation developed for DE in feed ingredients had greater accuracy than a published equation for DE. Conclusion: All fiber types are reasonably good independent variables for predicting DE of swine feeds. The best-fitting model for predicting DE of feeds employed neutral detergent fiber as an independent variable.
BACKGROUND/OBJECTIVES: The consumption of dietary supplements has shown an increase among young people in their 20s. We aimed to compare the use of dietary supplements and related factors between Chinese international and Korean college students living in South Korea. SUBJECTS/METHODS: We conducted online surveys of 400 Chinese international students and 452 Korean college students from January to February 2021. We analyzed the factors related to the use of dietary supplements by these students using multi-group structural equation modeling and logistic regression analysis. RESULTS: Approximately 65% of the Chinese international students and 93% of the Korean college students consumed dietary supplements at least once in the year preceding the survey. The common types of dietary supplements consumed by both groups of students were vitamin and mineral supplements, Lactobacillus products, and red ginseng products. Structural equation modeling showed that perception of the consumption of dietary supplements by family and friends positively influenced attitude toward dietary supplements. This effect was higher for Korean college students than for Chinese international students (P < 0.01). Attitude toward dietary supplements positively influenced their use, and this effect was higher for Chinese international students than for Korean college students (P < 0.001). Logistic regression analysis showed that the use of dietary supplements by Chinese international students was significantly associated with age, self-reported health status, interest in health, perception of and attitude toward dietary supplements, and length of residence in South Korea. Among Korean college students, it was associated with exercise frequency and attitude toward dietary supplements. CONCLUSION: This study showed significant differences in the use of dietary supplements and related factors between Chinese international and Korean college students. Therefore, nutrition education programs on dietary supplements need to have differentiated content for each group. Such differences also suggest that the industry should consider the relevant characteristics of college students while developing and marketing dietary supplements.
This study examined the dietary life by residence type of 409 university students (198 male and 211 female) in Chungnam They were divided into five groups according their residence: living in the family home a short distance from the university, living in the family home a long distance from the university, boarding house, self-boarding house, and university dormitory. In this study, the intake of food and nutrients and health, and dietary behaviors of each group were investigated through two-week questionnaire. The average age, height, weight, and BMI were 21.4, 175.3 cm, 68.9 kg, 22.3 in males, and 19.9, 162.3 cm, 53.3 kg, 20.2 in females, respectively. Dietary attitude of the students living in home was higher than that of the other student groups. The rate of breakfast intake and the frequency of eating 10 food items of subjects except processed food of self-boarding house group were lower than those of the other 4 student groups. These results suggest that university students of self-boarding house might have low ability of meal management and more reasonable nutrition education is needed for desirable food behaviors.
This study was performed to provide fundamental data on the dietary habits and food purchase types according to the stress patterns. The subject was 312 Chinese students in Gyeonggi region through a self-administered questionnaire. According to the results of the reliability analysis, the stress items showed an average of 2.91 and 0.846 for Cronbach alpha coefficient. The results of ANOVA analysis on the difference of dietary habits according to stress are as follows; There were significant differences for the meal frequency per day according to schoolwork, economic, general living, and dietary habits (p<0.05). Also, the general living pattern showed significant differences for the meal outside frequency and Chinese food intake (p<0.05). The results of ANOVA analysis on the difference of food purchase type according to stress are as follows; There was significant differences in degree of use of convenience foods according to interpersonal relationship, cooking method of convenience foods according to economics, the selection criteria of convenience foods according to schoolwork (p<0.05). The correlation coefficient of dietary habits and convenience food intake are 0.223, -0.147 in stress degree and dietary habits. In conclusion, I would like to provide the basic data necessary for the right choice of Chinese students' dietary habits and food purchases.
