The purpose of this study was to investigate the association between dietary behavior and temperament & character in preschool children, and to offer basic data that can be applied for nutrition education and counseling. A total of 211 parents of preschool children aged 3~5 years performed the Korean version of Preschool Temperament and Character Inventory (K-psTCI), a questionnaire based on Cloninger's seven-factor model of personality, along with a questionnaire about the dietary behaviors of their children. K-psTCI represented seven factors such as harm avoidance (HA), novelty seeking (NS), reward dependence (RD), persistence (P), self-directedness (SD), cooperativeness (CO), and self-transcendence (ST). The subjects were divided into either the high rank group or low rank group based on the mean score of each factor. The high rank group of HA showed significantly less physical activity and less appetite than the low rank group of HA. The children in the high rank of NS were more likely to have picky eating and a late night snack. The children in the low rank of SD or CO were more likely to have undesirable dietary behaviors, such as picky eating, too much snacking, and lower appetite than those in the high rank of SD or CO. In conclusion, individual temperament & character in preschool children may be associated with their dietary behavior, and understanding temperament & character in children may be important facts to screen and to develop an effective nutrition education program for children.

Lee, Joo Hee ; Shin, Ji Yeon ; Kim, Changim ;
The Korean Journal of Food And Nutrition, volume 27, issue 6, 2014, Pages 1022~1032
DOI : 10.9799/ksfan.2014.27.6.1022
This research is aimed at evaluating the nutrition knowledge and hygiene knowledge of people who are either foodservice employees or housewives and at providing data for conducting hygiene education by comparing the differences between the two groups. Both groups scored relatively high in nutrition knowledge with housewives scoring 9.9/12 and food service employees scoring 9.6/12. However, foodservice employees scored significantly higher in hygiene knowledge and degree of practice than housewives, A correlation was found between nutrition knowledge and the degree of hygienic practice and a significant correlation between hygiene knowledge and the degree of hygienic practice. The higher the hygiene knowledge was, the higher their degree of hygienic practice was. As for food hygiene information, foodservice employees obtained the information through hygiene education and lecture meetings, but housewives got their information through mass media. To summarize, mass media, which housewives can have easy access, must have programs for housewives to help them improve food hygiene in cooking, and programs for foodservice employees on washing food.

Kim, Dong-Su ; Shin, Kwang-Soon ;
The Korean Journal of Food And Nutrition, volume 27, issue 6, 2014, Pages 1033~1042
DOI : 10.9799/ksfan.2014.27.6.1033
To elucidate the novel biological function of Korean traditional vinegars, crude polysaccharides were isolated from vinegars manufactured at home and abroad, and their chemical properties and immuno-stimulating activities were examined. Three kinds of polysaccharides from Korean brown rice vinegar (KBV-0), Japanese brown rice vinegar (JBV-0) and Korean persimmon vinegar (KPV-0) showed higher immuno-stimulating activity. Component sugar analysis indicated that KBV-0 and JBV-0 mainly consisted of mannan, whereas KPV-0 existed as pectic materials. Three polysaccharides did not show any cytotoxicity to RAW 264.7 cell, whereas RAW 264.7 cells stimulated with KBV-0, JBV-0 and KPV-0 showed enhanced production of various cytokines such as IL-6, IL-12 and TNF-
in dose-dependent manners. However, the activity of KPV-0 was more potent than that of KBV-0 and JBV-0. Also, only KPV-0 augmented FcR II expression related with phagocytosis of macrophages. The results suggest among the tested vinegars, that the Korean persimmon vinegar has the most potent immune-stimulating activity, and it could possibly serve as industrial applications as functional materials.

Anthocyanins, a class of flavonoids, are natural water-soluble pigments, which are mainly found in vegetables and fruits. Anthocyanins have attractive pharmacological activities, such as anti-oxidant, anti-inflammatory, anti-cancer, and anti-diabetic. The purpose of this study was to investigate the protective effects of anthocyanins-rich fraction (ANF) from Korean purple sweet potato variety, "Shinjami", against hydrogen peroxide (
)-induced oxidative stress. In our results, pre-treatment of HepG2 cells with ANF (
) significantly prevented cell death and maintained cell integrity, following exposure to 0.9 mM hydrogen peroxide. The
-dependent production of intracellular ROS was also significantly decreased by pre-treatment with ANF (6 h,
). In addition, ANF increased the mRNA levels of antioxidant enzymes, catalase and glutathione level in
-treated HepG2 cells. These results indicated that ANF protected HepG2 cells against
-induced oxidative stress by inducing protective system.

This study was conducted to figure the usage status and satisfaction of food-related smartphone applications by generic characteristics and food purchase attributes of Seoul area workers. The results show that health vitality-oriented group, married compared to single, those with higher eating-out expenses possess more food-related applications (p<0.05). The primary reason for the usage of food-related applications was the need for food-related information (53.7%). The highest application subjects in use were restaurant-related information and recipe information. The real-life aid food-related applications utilized most were also restaurant information (60.7%) and recipe information (28.3%). Health vitality-oriented respondents especially turned out to use nutrition information and food functionality information often (p<0.01), and recipes or calories & diet information usage frequency was higher in women than in men (p<0.001). Restaurant-related information were more frequently used by singles, highly educated, and those with high income and eating-out expenses (p<0.05). Satisfaction of food-related applications was normal (3.06), showing that the satisfactory level is not yet high. Satisfaction regarding purchase attributes showed that the health vitality-oriented group (3.19) was more satisfied compared to other groups (p<0.05), and women (3.16) were more satisfied that men (2.89) were (p<0.05). Inconveniences of food-related applications were highest in usage fee (3.29), simplicity of information (3.28), lack of reliability of information and need for update (3.10). The results of this study implies that various subdivisions of food-related applications users should be implemented; at the same time, food-related applications covering diverse subjects that regard each group's characteristics should be developed in order to utilize food-related knowledge and information as a marketing tool in the food industry; this can efficiently be done by paying attention to the quality of information and updates within applications.

The purpose of this study was to evaluate the effect of dietary education on improving preferences to Korean traditional foods in upper grades schoolchildren. The education group consisted of 184 children (
=69), while the control group consisted of 135 children (
=40). Each group was selected from a different school in Changwon. In the education group, 12 lessons were implemented using educational materials based on sensory education. For the evaluation, pre- and post-surveys were performed in each group using self-administered questionnaire surveys. Variables in the questionnaire consisted of self-efficacy, subjective norms, cognitive attitude, food neophobia scale, eating frequency, preference, intake experience, and nutrition knowledge. After education, the knowledge score improved significantly in both groups. However, self-efficacy (p<0.01), subjective norms (p<0.01), cognitive attitude (p<0.001) and food neophobia scale (p<0.001) changed significantly in only the education group. The intake frequency of Korean traditional foods did not significantly increase in either group. However, the preferences and intake experience of the foods, which were offered in class and school meals, changed significant in only the education group. In conclusion, dietary education based on sensory education may be useful for developing a positive eating attitude for Korean traditional foods in children.

DOI : 10.9799/ksfan.2014.27.6.1141
The purpose of this study is to investigate the effects of arabinoxylan rice bran and endurance exercise training on TLR4 mediated protein expression in LPS-treated rats. The results showed that TLR4 as an important protein in the inflammatory response against lipopolysaccharide was shown to be significantly lower in both arabinoxylan supplement with exercise group and exercise group, thus the arabinoxylan rice bran had a higher inhibitory activity than arabinoxylan supplement group. However,
and MyD88 protein expression was not changed in arabinoxylan supplement with exercise training group, whereas
significantly decreased in 4 weeks of exercise training group. These results suggest that the supplement of arabinoxylan rice bran with exercise is likely to contribute to inflammation response and the arabinoxylan rice bran can be used as a possible safe alternative to the immunotherapeutic intervention.

For the reason for skipping breakfast, 'no time' showed the highest with 30.0% in the participating group, 'over sleep' and 'no appetite' showed the highest with 24.8% in non participating group. For the reason for not participating in SBP, 'breakfast should be eaten at home' showed the highest with 47.2% in non participating group and 'may get up early in the morning' showed the highest with 46.2% in participating group (p<0.01). To determine the factors affecting the intention to participate in SBP, logistic regression analyses were conducted for female middle school students. According to the logistic regression analysis, father's education level was independently associated with the intention to participate in SBP in female middle school students [Odds Ratios (OR) 2.38, 95% Confidence Interval (CI) 1.03~5.52]. Frequency of eating breakfast on weekdays (OR 1.36, 95% CI 1.01~1.81), Level of need for school breakfast (OR 0.52, 95% CI 0.35~0.76) and whether to approve school breakfast (OR 0.27, 95% CI 0.18~0.41) were independently associated with the intention to participate in SBP in female middle school students. In conclusion, proper educational efforts for importance of school breakfast could be useful plan to develop school breakfast program.

This study was conducted to develop for the elderly food that is safe, well-shaped, and easy to chew and swallow, using gelification. Gelatin, which has low adhesiveness, thereby lowering the possibility of being swallowed wrongly into the respiratory track, was used as a viscosity agent for the gelification. Water and gelatin amounts were adjusted to facilitate breaking the food with the tongue. Various foods for the elderly with chewing and swallowing difficulties were used for sensory assessment. Sensory panel consisted of 10 dietitians (10 women) in nursing care facilities. The sensory optimal composite recipes were determined by central composite design (CCD). The sensory measurements were significantly different in appearance (p<0.05), saltiness (p<0.05), sweetness (p<0.01), and overall quality (p<0.05). The optimum formulation of the Korean barbecue beef calculated by numerical and graphical method was 3.71 g of sugar and 19.53 g of soy sauce. Moisture content, hardness and adhesiveness of the Korean barbecue beef were 78.85%, 2.40, -1.87, respectively. The result shows that food for the elderly, which is easy to chew and swallow, using gelification will have sufficient competitiveness in terms of safety, taste, and preference. The development of food for the elderly that take into account the difficulties in chewing and swallowing among the elderly, reflects their preference, and has sufficient nutrients, is important to enable the elderly to enjoy their meals. Also, as the Korean society is getting older, it remains one of the biggest social challenges.

The object of this study was to employ effective marketing methods using SNS by determining how food-related SNS usage characteristics have influence on dine-out motivation and restaurant satisfaction and how this affects people's quality of lie. Survey respondents were men and women who have had used some kinds of food-related SNS. The survey included general characteristics of respondents, food-related SNS usage characteristics, dine-out motivation, restaurant satisfaction, and food-related quality of life. Food-related SNS usage characteristics were divided into convenience, effective time-spending, and informative; Dine-out motivation was sorted into entertainment motivation and social motivation by factor analysis. Analysis of the connections between the variables by AMOS showed that among food-related SNS usage characteristics, convenience did not have a significant influence on either entertainment or social motivation. Informative had a positive effect on entertainment motivation (p<0.05), but not on social motivation. On the other hand, effective time-spending through food-related SNS had an impact on both entertainment (p<0.001) and social (p<0.05) motivation. Moreover, the effect of dine-out motivation on restaurant satisfaction showed that entertainment motivation (p<0.05) and social motivation (p<0.01) both have significant influences on restaurant satisfaction. Also, restaurant satisfaction turned out to affect quality of life (p<0.05). As a result of this study, the usage of food-related SNS did not directly influence customers' restaurant satisfaction and quality of life; (p<0.05). As a result of this study, the usage of food-related SNS did not directly influence customers' restaurant satisfaction and quality of life; however, it had an impact on dine-out motivation and gain pleasure of dining out and help improve the quality of life in the long run; thus, it is believed that marketing strategies thorough SNS by restaurant industry are required.
