Retarding effects of the dietary fibers from persimmon peels (PTDF ; total dietary fibers, PIDF ; insoluble dietary fibers, PSDF ; soluble dietary fibers) and dried jujubes (JTDF ; total dietary fibers, JIDF ; insoluble dietary fibers, JSDF ; soluble dietary fibers) on glucose, bile acid and cadmium transport were evaluated by in vitro dialysis sack method. These effects were compared with those of commerical citrus pectin, CM-cellulose (CMC) and $\alpha$-cellulose. Yields of PTDF, PIDF and PSDF on wet weight basis were 14.04% , 11.61%, 1.76%, respectively, and those from dried jujubes were 14.80%, 9.98% and 2.80%, respectively. The amount of soluble fibers in JTDF was higher than PTDF. Soluble fibers had the retarding effects on glucose transport but insoluble fibers did not have. CM-cellulose showed the greatest retarding effect, which was followed by citrus pectin and JSDF. Among the soluble fibers, PSDF had the lowest retardig effect. Retarding effect of TDF was dependent upon the amount of SDF in TDF. Regarding bile acid dialysis , insoluble dietary fibers as well as soluble dietary fibers showed the retarding effects, among which JSDF had the greatest retarding effects, among which JSDF had the greatest retarding effect, followed by citrus pectin. Among the extracted fibers, dietary fibers from dried jujubes were more effective than these from persimmon peels, and SDF seemed to show higher retarding effects than IDF and TDF. On cadmium transport retardation , all dietary fibers except $\alpha$-cellulose had the retarding effects and PSDF showed the greatest effect which was followed by PIDF and CMC, The extracted fibers showed higher retarding effect on Cd transport than glucose and bile acid transport, and dietary fibers from persimmon peels showed higher retarding effects than those from dried jujubes.

The present study was conducted to assess the dietary and nutritional status of thiamin in fourty-two elderly women. Dietary intake was determined by 24hour recall method and nutritional status of thiamin was determined by measurement of transketolase activity in erythrocytes. Average dietary intake of energy and thiamin were found to be low, and not more than 78% and 63.2% of Recommended dietary allowances(RDA) respectively. Transketolase activity in erythrocytes was distributed in the range of 0.227-0.589mU/mgHb and the mean value and 0.434mU/mgHb. The mean value of Thiamin pyrophosphate effect(TPP effect) was 24.0% and the range was from 9.36% to 83.9%. It appeared that 95% of 42 elderly women were severely or marginally deficient in thiamin status, showing 22 persons to be above 20% and 18 persons to be 15-20% of TPP effect. Transketolase activity and TPP effect did not show any significant correlation with dietary thiamin intake.

Retarding effects of the dietary fibers from tangerine peels on glucose, bile acid and cadmium transport were evaluated by dialysis method, and were compared with those of commercial dietary fibers(citrus pection, CM-cellulose, guar gum, $\alpha$-cellulose). Yields of total (TDF), insoluble(IDF) and soluble dietary fibers(SDF) from tangerine peels on the fresh matter basis were 2.84%, 1.95% and 0.39% respectively. The amount of insoluble fibers was 5.2 times higher than that of soluble fibers. Soluble fibers(guar gum, CM-cellulose, SDF, pectin) had the retarding effect on glucose transport, while IDF, TDF and $\alpha$-cellulose did not have. Guar gum showed the greatest effect, followed by CM-cellulose, SDF and pectin. Among the extracted fibers, only SDF had the effect on glucose transport retardation. Regarding bile acid dialysis, guar gum had the greatest retarding effect, and all dietary fibers from tangerine peels, especially SDF, showed the effect of bile acid retardation. On cadmium transport retardation, CM-cellulose had the greatest effect, followed by SDF, TDF, IDF, guar gum and pectin. Among the extracted fibers, SDF had the greatest effect on Cd trasport transport retardation. The extracted dietary fibers showed higher retarding effect on Cd transport than glucose and bile acid transport, and the effect of SDF was higher than IDF.

The purpose of this study was to investigate the effect of green dietary life recognition and low-carbon green life practice on health-related dietary habits in high school students. The subjects were 367 high school students in the Incheon area. This cross-sectional survey was conducted using a questionnaire, and data were analyzed with the SPSS 20.0 program. According to the findings, green dietary life recognition were categorized into two sub-factors: 'Eco-friendly traditional dietary life', and 'Life of consideration and thanks'. Low-carbon green life practice was 'Low-carbon green life', and health-related dietary habits were categorized into four sub-factors: 'Vegetables-oriented traditional dietary habits', 'Balanced dietary habits', 'Life practice for health', and 'Various cereals intake'. Green dietary life recognition showed a significantly positive relationship with all sub-factors of health-related dietary habits (p<0.05), whereas 'Eco-friendly traditional dietary life' had no significant effect on 'Balanced dietary habits'. Low-carbon green life practice showed a significantly positive relationship with all sub-factors of health-related dietary habits (p<0.01). Students who received green growth education showed significantly higher health-related dietary habits than those who did not (p<0.01). Girls showed significantly higher green dietary life recognitions and low-carbon green life practice than boys (p<0.01). Therefore, more green dietary life and low-carbon green life education programs targeting students are need. Voluntary activities, along with green dietary life and low-carbon green life education will help students improve their health-related dietary habits.

In this study, a survey was carried out on 208 students at middle schools in Gyeonggi-do through May 1 to July 20, 2011, with the purpose of figuring out how eating attitudes of middle school students affect their psychological achievement and self control. The results were as follows. First, the effect of eating attitudes on the psychological achievement of middle school students demonstrated that regular dietary life, dietary life and health had a statistically significant positive effect on psychological achievement. Second, the effect of eating attitudes on self control in middle school students showed that balanced dietary life, dietary life and health had a statistically significant positive effect on self control. The above findings confirmed that regular and healthy dietary life connected directly with health, which was a factor that makes them think positively about psychological achievement. Besides, for eating self control, as balanced dietary life in eating attitudes was important. And as this had a positive effect on their self control, could improve their eating attitudes. Consequently, the regular eating attitudes and balanced dietary life in eating attitudes of middle school students can make their psychological achievement and eating self control for the nutrition and health care.

The physicochemical, rheological and sensory characteristics of 'BACKSULGIES', which was added with potato peel, guar gum or polydextrose, were investigated. The maximum acceptable addition ratio of dietary fiber to 'BACKSULGI' was 10%. And optimal addition ratio was 3% for all samples. The water binding capacity was affected by dietary fiber sources and incubation conditions (temperature and time). The Guar gum had me highest value of water binding capacity. The solubility was highly related with water binding capacity and me swelling power was increased with temperature increment. The degree of gelatinization was not significantly different with dietary fiber sources. But me values of gelatinization of 'BACKSULGIES' added with dietary fibers were significantly higher than mose of 'BACKSULGI' with no dietary fiber. Generally hardness and brittleness incresed along with storage time. But me hardness of 'BACKSULGIES' added with dietary fibers was significantly lower man those of 'BACKSULGI' with no dietary fiber. The retardation effect of dietary fibers for retrogradation of 'BACKSULGIES' was also proved by time constant determination of Avrami equation. Sernsory evaluation revealed that me addition of dietary fibers did not reduce the organoreptic quality. Therefore potato peel 3%, guar gum 3%, polydextrose 3% were optimum addition ratio which could be accepted as conventional 'BACKSULGI'. As me results of this study, it was proved mat the additions of dietary fibers to 'BACKSULGI' had the retardation effect of retrogradation.

An experiment was conducted to evaluate the effects of dietary acetyl-L-carnitine (ALC) on growth performance, carcass characteristics, meat quality and lipid metabolism in broilers. A total of 240 one-day-old male Arbor Acres broilers were randomly allocated to 4 dietary treatments (0, 300, 600, and 900 mg/kg dietary ALC supplementation, respectively). Compared with the control treatment, addition of ALC resulted in lower (linear effect, p<0.05) ADG and AFI. Abdominal fat percentage decreased (linear effect, p<0.05) as dietary ALC was increased, but there was no effect on dressing percentage, breast muscle percentage or thigh muscle percentage. Breast muscle pH value 24 h post-mortem increased (linear effect, p<0.05), but there were no significant differences among treatments. However, thigh muscle pH value increased (linear effect, p<0.05) as dietary ALC was increased. Breast and thigh muscle $a^*$ values increased (linear effect, p<0.05), and breast and thigh muscle $b^*$ values decreased (linear effect, p<0.05) with increased ALC in the diet. In addition, breast and thigh muscle shear force value decreased (linear effect, p<0.05) as dietary ALC was increased. Total cholesterol, triglyceride, low-density lipoprotein cholesterol and lipoprotein lipase decreased (linear effect, p<0.05) and free fatty acid and lipase in serum increased (linear effect, p<0.05) with increased ALC in diets.

This study has dealt the effect of Ca regulating hormones and dietary Ca levels on Ca metabolism. Animals(BALB/c mice) were divided into three dietary groups(high and medium Ca and Ca free) and hormones including parathyroid hormone(PTH), calcitonin(CT), cholecalciferol(Vit D) were i.p. injected. After feeding experimental diets for five weeks, mice were anaethetized and sacrificed by heart puncture. We found that femur growth of mouse was slightly increased by high dietary Ca without showing statistical significance comparing to low dietary Ca group. The combination of PTH and CT showed the same effect when dietary Ca was high. At the same time, total mineral retention in bone was most affected by dietary Ca. In general, high Ca diet elevated Ca level in the serum. When dietary Ca was low, PTH stimulated Ca release from the bone into the serum, which was shown to be inhibited by CT treatment. Comparing to the control, PTH, Vit D and CT together tended to inhibit serum Ca level at high and medium dietary Ca. PTH and Vit D inhibited Ca reserve in the liver at all dietary levels of Ca. Both PTH and Vit D stimulated bone Ca retention when dietary Ca was low, but this effect was reversed when dietary Ca was high. When PTH, Vit D and CT were administered together, bone Ca level was greatly enhanced at low dietary Ca than at high dietary Ca, which suggests that these hormonal cooperation is needed for proper bone density maintenance especially when dietary minerals are not sufficient.
