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.

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.

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.
