        The objective of this study was to evaluate novel usability as natural anti-obesity supplement of Selaginella tamariscina extract. The total phenol contents and total flavonoid contents were 60.29±3.11 GAE mg/g and 14.90±0.34 QE mg/g, respectively. To evaluate anti-obesity activity of Selaginella tamariscina extract, pancreatic lipase inhibition activity as well as its inhibition effect of lipid accumulation in adipocytes were conducted by Oil Red O staining and lipolysis assay. The result of pancreatic lipase inhibition activity of S. tamariscina extract showed a wide range between 40 and 73% dose dependently. While the incubation of 3T3-L1 cells with S. tamariscina extract inhibited differentiation of preadipocytes and reduced lipid accumulation, the level of released free glycerol into culturing medium was increased in multiple concentrations. These results showed that S. tamariscina extract inhibit adipogenesis and pancreatic lipase activity. Thus, S. tamariscina extract can be a candidate for regulating lipid accumulation in obesity.

        As consumers are aware of their health and are more conscious of environmental conditions, there is an increasing demand for agri-foods obtained from organic agricultural practices. The present study aimed to investigate the physicochemical quality characteristics of blueberries. The weight, length, moisture contents, color (Hunter L, a, b), soluble solids contents, pH, and acidity were measured for their quality characteristics. In addition, ABTS radical scavenging activity was analyzed for antioxidant activities of organically and conventionally grown blueberries. Organically grown blueberries showed a greater weight, soluble solid contents, and pH than conventionally grown ones. Especially, organically grown blueberries showed significantly (p<0.05) higher weight and pH. Moisture contents of organically and conventionally grown blueberries were similar. L and b values of organically grown blueberries were higher than those of conventionally grown blueberries. ABTS radical scavenging activities of organically grown blueberries (36.4%) were higher than those of conventionally grown ones (36.4%), but the difference was not significant. Further studies are recommended to evaluate other differences between organically and conventionally grown blueberries.

        The purposes of this study were to investigate the eating of breakfast by female middle school students in Seoul, the perception of the school breakfast program (SBP), and determine the factors affecting the intention to participate in SBP. Out of 340 questionnaires distributed to the female middle school students, 334 were returned (98.2% response rate) and 323 were analyzed. The subjects were categorized into two groups by the intention to participate in SBP. Subjects were classified as participating and non participating groups. As a result of analyzing the breakfast intake frequency, 'hardly eat' showed the highest with 18.5% in the participating group and 10.3% in non participating group, while 'eat every day' showed 38.2% in the participating group, and the highest with 65.5% in non participating group (p<0.001). 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.

        A research was conducted on Seoul regional elementary, middle, and high school nutritionists to study about their perception of HACCP control standards & performance conditions and sanitation & safety inspection, to seek for more efficient methods of school meals' sanitation system settlement. All surveys were distributed and collected via email. A total of 305 survey papers were collected, and out of these, 300 school results were analyzed. As for CCP 1 performance conditions, 43.3% of the nutritionist put emphasis on temperature control for cooking duration and 71.0% said that they manage both temperature and PHF food control. In CCP 2 stage, 65.8% of the nutritionists maintained the food's temperature, and 56.7% documented the recordings after cooking. A total of 79.3% of the schools scored above 90 points on school meal sanitation & safety inspection, 3.72 points on necessity for revisions, 3.38 points on objectivity, and 3.34 points on reliability. As for these results, a clear CCP control criteria as well as training must be set. Also, because the necessity of revision for sanitation & safety inspection is higher than reliability and objectivity, appropriate complementary measures must be taken.

        The purpose of this study was to investigate the relationship between bone mineral density(BMD), body composition and life styles of female college students. The subjects were 334 students with a mean age of 21.0 years. BMDs of forearm and calcaneus were measured by dual energy X-ray absorptiometry, and body composition was measured by bioelectrical impedence analysis. The means for weight, height, and body mass index(BMI) of the subjects were 55.7 ㎏, 161.0 ㎝, 21.5 ㎏/m2, respectively. Grouping by the BMI, 13.2% of the subjects were classified as overweight, and 11.1% of the subjects as obese group. BMD in the forearm and calcaneus were 0.390 g/cm2, 0.514 g/cm2. In the forearm, 58.1% and 9.6% of the subjects were classified as osteopenia and osteoporosis, respectively, and in the calcaneus, 12.0% and 0.3% of the subjects were classified as osteopenia and osteoporosis, respectively. Body weight, skeletal muscle mass, lean body mass, fat mass and BMI were positively correlated with BMDs in the forearm and calcaneus(r=0.180~0.495, p<0.01~0.001), and height, % body fat and waist-hip ratio(WHR) were positively correlated with BMDs in the calcaneus(r=0.213~0.239, p<0.001), but not in the forearm. The factors such as beginning age of cigarette smoking and alcohol drinking and exercise had significant influence on BMD(p<0.05; p<0.001), whereas sleeping hours, activity level, frequency of exercise, meal times, frequency of snack and fried food intake, breakfast skipping and amount of meal had not significant influence on BMD. Therefore, the acquisition of balanced body composition is necessary through the increase of fat free mass and muscle mass, not through the increase of fat mass among female college students.

        The purpose of this study was to investigate foodservice management practices in the child care centers and kindergartens. Interviews were held from May to July 2008 to understand the current situation concerning foodservices in Seoul and Gyeonggi provinces. Surveys were sent out from August 2008 to April 2009 to 1, 478 child care centers and 299 kindergartens via the postal service. Among them, 203 child care centers(13.7%) and 64 kindergartens(21.4%) responded. One of the largest concerns while preparing the food was nutrition(68.7%, 69.8%, respectively) followed by sanitation(24.4%, 27.0%, respectively). The most frequently referred sources for planning the menu were the Seoul child care information center(55.4%) for child care centers and kindergarten related internet sites(39.0%) for the kindergartens. In general, the child care center principal was in charge of planning the menu(40.1%). Child care centers and kindergartens purchased ingredients mostly from large retailers(55.3% and 44.7%, respectively), whereas 46.0% and 56.3% of those did through foodservice suppliers. Dietitians were rarely employed at these facilities, and this may cause unprofessional foodservice management.
