The purpose of this study was to investigate the nutrition knowledge, perception, and intake frequency of milk and milk products among middle school students as well as provide the basic data needed for increasing milk and milk product consumption. To achieve the purpose of this study, a survey with 385 students of four middle schools located in Chuncheon was conducted. The level of nutrition knowledge of milk and milk products in females was slightly higher than that in males (p<0.01). Flavored milk and ice cream were preferred the most in each category, and ‘taste’ influenced the selection of milk and milk products the most. The intake frequency of whole milk was the highest, and that of flavored milk was lowest among various milks. Ice cream showed the highest intake frequency while cheese showed the lowest among milk products. Male students showed higher intake frequency of milk and milk products. Groups having high level of nutrition knowledge showed the highest intake of whole milk, whereas groups having a low level of nutrition knowledge preferred processed milk, low fat or non-fat milk, and cheese the lowest.
The purpose of this study was to determine the relationship between children’s dietary self-efficacy, general characteristics and mother’s parenting self-efficacy among elementary school students. Mother’s parenting self-efficacy was significantly higher as parents’ educational levels increased (p<0.001), as family monthly income level increased (p<0.001), and when father’s job was professional or managing work (p<0.001). Children’s dietary self-efficacy was meaningfully higher when parents’ educational levels were higher (p<0.01), and family income level was higher (p<0.01). Mother’s parenting selfefficacy showed a correlation with children’s dietary self-efficacy (p<0.001). All factors comprising parenting self-efficacy, such as ‘general parenting self-efficacy’ (p<0.001), ‘healthy parenting self-efficacy’ (p<0.001), ‘communication parenting self-efficacy’ (p<0.001), ‘educational parenting self-efficacy’ (p<0.001), and ‘control parenting self-efficacy’ (p<0.001) showed correlation with children’s dietary self-efficacy. It is suggested that in order to improve children’s dietary self-efficacy and mothers’ parenting self-efficacy, families, schools, and communities must put forth a concerted effort. By complementing existing nutritional programs focusing on nutritional knowledge, one can develop a education program and social support to enhance children’s dietary self-efficacy and mothers’ parenting self-efficacy.
In this study, the eating out behavior and recognition of salinity in restaurant food in Jecheon area were examined. Demographic characteristics of the subjects, eating out behavior and perception of salinity in food purchased in restaurants were surveyed. Also salinity of the high Na-containing menus were measured using salimeter. Exactly 51.6% of the study subjects usually ate out more than one to two times per week. A large percentage (88.6%) of the subjects mentioned that they ate more than half the amount of liquid in their dishes. The study participants recognized that the salt concentrations of stews, soups and noodles in their orders were high. JJamppong was recognized as the most salty among nine kinds of eating out menus, whereas mulnaengmyeon was the least. Although the recognized salt concentration of mulnaengmyeon was relatively low, this dish had the highest salinity out of nine eating out menus. Relative salinities of eating out menus were higher than absolute salinity mostly except yukgaejang. It is necessary to supply exact nutrition information and widely implement nutrition labeling. Furthermore, consumers should personally be careful to limit consuming food with high sodium levels when dining at restaurants and eat less liquid in dishes.
The quality characteristics of Omija (Schizandra chinesis Baillon) extracts under various extraction temperatures and times were examined. The pH level of the extracts ranged from 3.35-3.47. The sugar and solid content of the samples significantly increased with increasing extraction temperatures and times (p〈0.01). In contrast, the lightness of the extracts decreased with increasing extraction temperatures and times (p〈0.001). In a palatability test, extracts boiled at 80℃ for 30 minutes scored high in terms of color, flavor, turbidity, sourness, and overall acceptability. Hydroxy radical scavenging activity and polyphenol content of the extracts significantly increased with increasing extraction temperatures and times (p〈0.01). Furthermore, direct correlations between hydroxy radical scavenging activity and polyphenol content (or flavonoid content) were established through simple regression (r〉0.9) for different extraction temperatures and times. From these results, extracts boiled at 80℃ for 120 minutes is the best to product omija beverage considering functionality and sensory evaluation as well.
Quantitative analyses of naturally occurring methanol were performed for the alcoholic beverages commonly consumed in Jecheon, Chungbuk province, South Korea. The headspace analysis method was optimized for the low and high alcoholic beverages. The external standard method was applied due to the overlapping of 2-propanol and 2-butanol (the internal standard candidates) with target sample matrix peaks. The target samples were selected based on the retail sales amounts of alcoholic beverages in the largest retailer food-mart chain, Jecheon, Chungbuk province, South Korea. There was no sample containing methanol over 0.5 ㎎/㎖, the Korean maximum level of methanol in alcoholic beverages (1.0 ㎎/㎖ for fruit originated liquor etc). The total exposure amount of methanol via alcoholic beverages was estimated based on the daily alcohol consumption of 40 g. The hazard indices calculated by methanol RfD 0.5 ㎎/㎏ bw day (US EPA) and ADI 20 ㎎/㎏ bw day (proposed by Lachenmeier etc.) were 0.301 and 0.008, respectively. As with the hazard index, aggregate exposures below a HI of 1.0 will likely not result in adverse noncancer health effects over a lifetime of exposure. Then the methanol exposure via the alcoholic liquours might not hazard to Jecheon citizen.

In this study, Astragalus membranaceus powder was added (3, 6, 9%) during yeast bread preparation and its effect on product quality was examined. The results showed that the dough pH increased as the Astragalus membranaceus powder content increased. However, dough volume during fermentation did not differ significantly among the samples. Bread volume decreased (p<0.001) with an increasing amount of Astragalus membranaceus powder. Also, as the Astragalus membranaceus powder content increased, the Hunter’s color ‘L’ value of the crust decreased and the ‘a’ value increased, and for the crumb, the ‘L’ value decreased and the ‘a’ value increased. Textural property analysis indicated that hardness increased with an increasing amount of Astragalus membranaceus powder. However, up to the 6% level, there were no sensory attribute differences among the samples.
Antioxidant activity of Astragalus membranaceus, Polygonatum stenophyllum, Angelica gigas, Acanthopanax sessiliflorus and Angelica pubescens extracts cultivated in Jecheon prepared with different solvents were determined by 1,1-diphenyl-2-picrylhydrzyl(DPPH) radical scarvenging ability and thiocyanate method . The highest hydroxy radical scarvenging activity was shown in Acanthopanax sessiliflorus, while the lowest was in Polygonatum stenophyllum. Angelica gigas showed strong antioxidant activity by thiocyanate method. Methanol extracts and water extracts showed higher antioxidant activities than ethanol extracts. Angelica pubescens showed the highest polyphenol contents and Acanthopanax sessiliflorus showed the highest flavonoid contents. Direct correlation between the hydroxy radical scavenging activity and polyphenol contents or flavonoid contents was established by simple regression(r>0.8) in each solvent extracts. Among medicinal plants cultivated in Jecheon, Acanthopanax sessiliflorus and Angelica pubescens showed strong antioxidant activities. These results suggest that methanol or water extracts of several medicinal plant cultivated in Jecheon could be used as natural antioxidants.
