This study compared nutrition knowledge, dietary behaviors, and checking behaviors of food and nutrition labels between Korean and Chinese university students to obtain useful data for development of an education program for healthy dietary life. The data were collected by a self-administered questionnaire in Korea and China. Frequencies, t tests, ${\chi}^2$ tests, Cronbach's ${\alpha}$, and Pearson's correlation coefficient analysis were conducted by SPSS Win. V.21.0. The levels of nutrition knowledge and dietary behaviors were not high. Korean students showed higher percentage of correct answers about nutrition knowledge and levels of dietary behaviors than Chinese students. The means of degree of checking contents of food labels were 3.46 points for Korean students and 3.11 for Chinese students. Both groups of students showed the highest degree of checking milk and dairy products. The degree of understanding nutritive component labeling of Chinese students was higher than that of Korean students. Both groups of students showed higher than normal levels of confidence about nutritive component labeling and necessity of education on food and nutrition labels. The most preferred method of education on food and nutrition labels was broadcast media for both groups of students. In addition, there were significant correlations among nutrition knowledge, dietary behaviors, checking degree of food labels, checking degree of nutritive component labeling, and experience of nutrition education.

Predictive modeling was applied to study the growth of microorganisms related to spoilage in frankfurter sausage containing various levels of dietary fiber (0, 1, 2, and 3%) from rice bran and to estimate its shelf-life. Using the Baranyi model, total viable cells, anaerobic and psychrotrophic bacteria were measured during 35 days of cold storage ($<4{\pm}1^{\circ}C$). The lag times (LT) demonstrated by control and treatment groups were 6.28, 623, 6.24, and 6.25 days, respectively. The growth rate of total viable cells in each group were 0.95, 0.91, 0.92, and 0.91 (Log CFU/g/day), respectively. The anaerobic and psychrotrophic bacteria had lower initial ($y_0$) and maximal bacterial counts ($y_{max}$) than total viable cells. Also, the anaerobic and psychrotrophic bacteria possessed lower growth rate and longer lag time than total viable cells. The estimated shelf-life of frankfurter containing rice bran fiber by the growth rate of total viable cells was 7.8, 7.9, 7.9, and 7.7 days, respectively. There were no significant differences in shelf-life as a function of fiber content. In other words, the addition of dietary fiber in sausage did not show the critically hazardous results in growth of microorganism. The 12 predictive models were then characterized by high $R^2$, and small RMSE. Furthermore, $B_f$ and $A_f$ values showed a very close relationship between the predictive and observed data.

Objectives The purpose of this study was to examine the daily lifestyle of Vietnamese immigrant women and to find out if they could affect health-related quality of life improvement. Methods The subjects of this study were 273 women who immigrated to Korea from Vietnam. This study was conducted at Daejeon and nearby Healthy Family Support Centers from September 2019 to January 2020 with the cooperation of the Daejeon City Healthy Family Support Center. Correlation analysis was performed between lifestyle and quality of life, and ANOVA analysis was performed to confirm the difference in health-related quality of life scores for each subgroup of dietary nutrition, sleep quality, and physical activity. A regression analysis was conducted to investigate the contribution of dietary nutrition, sleep quality, and physical activity to the quality of life of Vietnamese immigrant women. The significance level was p<0.05. Results Physical activity showed significant correlations with Euro Quality of Life -Visual Analogue Scale (EQ VAS), sleep quality with EQ VAS and Euro Quality of Life-5Dimension (EQ-5D) Index, and dietary nutrition with EQ-5D Index. There were significant differences in EQ VAS and EQ-5D Index scores for each sleep quality subgroup, and a significant difference in EQ VAS scores for each activity subgroup. The quality of sleep was found to have the greatest effect on EQ VAS and EQ Index of Vietnamese immigrant women, and physical activity on EQ VAS and dietary nutrition had some influence on EQ-5D Index. Conclusions Quality of sleep is closely related to health-related quality of life, and plays an important role in health-related quality of life for Vietnamese immigrant women.

This experiments was conducted to determine the effect of dietary fiber(DF) levels with diets of isocaloric (3,010 kcal/1kg diet) and isoprotein(21% of diet) on colored brolier chicks(Juk jun hatchery farm). Four groups of 6 chicks 4 replication. were fed corn-soy meal diets containing 0% (DF, 5%), 2%(DF, 6%), 4%(DF, 7%), and 6%(DF, 8%) of dehydrated alfalfa meal(AM) from 21 to 42 days of age. The addition of dietary fiber levels to the broiler chicks diets did noty affect body weight, feed efficiency, energy efficiency and protein efficiency, but affect feed intake of chicks fed 6% of fiber. The level of fiber diets did not affect gizzard weight of female(1.45g/100g BW) and male(1.25g/100g BW), but affect small intestine length of female. When comparing two the dietary fiber levels, 5% and 8%, the contents of the total serum cholesterol was slightly higher in chicks fed 5% of fier than that of 8% without significant. However, total serum cholesterol levels of female(121mg/dl) and male(119mg/dl) were not influenced by increased dietary fiber levels. The liver weight was not influenced by increasing of dietary fiber levels (female 2.03g and male 2.05g/100g BW). The yields of dressed weight(72% of shrunk body weight), skin weight)11% of dressed weight) were not influenced by increased dietary fiber.

This study was conducted to investigate the effect of dietary fiber(DF) levels on the meat quality in colored broiler. Colored broiler were fed on containing corn-soy basal diet(DF 5%) and high level(DF 6,7 and 8%) of dietary fiber diets for 7 weeks. Dietary fiber level of diet was make up by adding some alffalfa meal. Colored broiler meats were stored at 3$\circ$ for 24hr after skaughter, and used to analyze physico-chemical properties. Proximate component, pH, shear force value, myofibril fragmentation index, water holding capacity, cooking loss, protein extractability, fatty acid composition, Hunter's L, a value and palatability of cooked meat were not significantly affected by dietary fiber levels, whereas the Hunter's value of meat was significantly affected bty dietary fiber levels for the final period of feeding. Crude protein content, myofibril fragmentation index, water holding capacity, protein extractability and Hunter's b value of breast meat's were higher than thigh meat's, but crude fat content, pH, shear force value, cooking loss, palmitoleic acid, linolenic acid, and Hunter's a value were lower, regardless of dietary fiber level.

This study determined the effects of dietary restriction on growth and the expression of lipid metabolism and growth hormone signaling genes in the longissimus dorsi muscle (LM) of Korean cattle. Thirty-one Korean cattle steers (average age 10.5 months) were allocated to normal (N; n = 16) or dietary restriction (DR; n = 15) groups. The feeding trial consisted of two stages: for the 8-month growing period, the DR group was fed 80% of the food intake of the normal diet, and for the 6-month growth-finishing period, the DR group was fed a DR total mixed ration with 78.4% of the crude protein and 64% of the net energy for gain of the normal diet. The LM was biopsied 5 months (period 1 [P1] at 15.5 months of age) and 14 months (period 2 [P2] at 24.5 months of age) after the start of feeding. The mRNA levels were determined using real-time polymerase chain reaction. Body weight, daily feed intake, average daily gain, and feed efficiency were lower in the DR group compared with the normal group at both P1 and P2. At P1, the lipogenic fatty acid synthase (FASN) mRNA levels were lower (p<0.05) in the DR group compared with the normal group. The DR group tended (p = 0.06) to have higher of levels of growth hormone receptor (GHR) mRNA than the normal group. At P2, the DR group tended to have lower (p = 0.06) androgen receptor (AR) mRNA levels than the normal group. In conclusion, our results demonstrate that dietary restriction partially decreases the transcription of lipogenic FASN and growth hormone signaling AR genes, but increases transcription of the GHR gene. These changes in gene transcription might affect body fat accumulation and the growth of the animals.

In this study, we analyzed the dietary style of Chinese singles; in addition, the effect of convenience food consumption on the quality of life of singles was evaluated through construct model development on the relationship between the frequency of consumption and satisfaction with convenience food and quality of life. A statistical analysis of 153 surveys from Tianj was conducted using SPSS 12.0 for Windows and SEM using AMOS 5.0 statistics package. The reliability of the data was confirmed by an exploratory factor analysis and Cronbach's alpha coefficient. The measurement model was confirmed as appropriate by a confirmatory factor analysis of the measurement model in conjunction with AMOS. The results of a factor analysis were as follows. Dietary style was categorized into four factors. The level of satisfaction with convenience food was categorized into seven factors and quality of life was categorized into four factors. The reliability of these findings was supported by a Cronbach's alpha coefficient of 0.6 and higher for all the factors. For the level of satisfaction with convenience food based on dietary style and the quality of life of singles, a structural equation model was constructed and analyzed. The results of all tests indicated that the model satisfied the recommended level of goodness of fit index and thus, the overall research model was appropriate. The current study highlights the increased interest in eating habits of singles and is necessary for further improvement in nutrition education.

BACKGROUND/OBJECTIVES: This study examines life stress, dietary attitudes, and snacking frequency for college students living in Seoul and Gyeonggi Province. The purpose of this study is to assist college students feeling stressed by offering desirable dietary attitudes and choices of the appropriate snacks by providing educational materials that offer appropriate nutrition education and nutritional information. SUBJECTS/METHODS: A survey was conducted on a total of 600 college students aged 19-29-year-olds living in Seoul and Gyeonggi Province (234 male students and 366 female students). Collected data were analyzed using SPSS WIN 28.0 program. RESULTS: Life stress among college students did not differ significantly between the genders. Male students were more stressed about lover (P < 0.01), while female students were more stressed about value problems (P < 0.01) and future problems (P < 0.05). Dietary attitude ratings were 3.1 for both male and female students with no significant difference. The overall snacking frequency was 4.1 times/day-4.2 times/day for male students and 4.0 times/day for female students-thus, there was no significant difference. Male students consumed 'beverage' (P < 0.01) more frequently than female students. Life stress and snacking were positively correlated for 'biscuit/cookie,' 'chip,' 'cereal,' 'juice/smoothie,' 'café americano,' 'café latte,' 'tea,' 'jelly,' 'chocolate,' 'rice cake,' 'milk,' 'flavored milk,' and 'ice cream' among male students. Among female students, life stress and snacking were positively correlated with 'cereal,' 'caramel,' and 'soymilk,' and negatively correlated for 'biscuit/cookie' and 'carbonated drink.' CONCLUSIONS: College students should manage their stress by identifying its causes and learning how to deal with stressful situations. Additionally, providing them with proper nutrition education based on the correct nutritional information is essential for promoting good food attitudes and snacking behaviors.

The purposes of this study were, 1) to investigate the causal relationship between customer's life-style and motivation of eating-out, and 2) to research the causal nexus between motivation of eating-out and satisfaction of attributes to choose the restaurant. Reliability analysis, factor analysis, and Structure Equation Model(SEM) were adapted by Windows SPSS 10.0 and Amos 4.0. Life-style was divided into 7 factors and eating-out motivation into 5. Life-style influenced significantly each motivation of eating-out. It had positive influence on 'Reception and congratulation', 'Change of dietary life', 'Economic saving', "'Preference motivation', and 'Advertisement and companion's need', but negative influence on 'Reception and congratulation', 'Change of dietary life', and 'Preference motivation'. Customer's motivation of eating-out also influenced significantly the attributes. Factorl 'Reception and congratulation' had positive influence on all attributes except for 'Transportation convenience and distance to the shop'. Factor 2 'Change of dietary life' had negative influence on 'Food's taste, quantity, price', 'Sanitation and cleanness', and 'Staff's service quality' Factor 3 "Economic saving' had positive influence on 'Food's taste, quantity, price' and 'Transportation convenience and distance to the shop'. factors 'Advertisement and companion's need' had positive influence on 'Atmosphere of restaurant' and negative influence on 'Food's taste, quantity, price'.
