  • The effect of three different grains supplemented diet as a dietary carbohydrate source on the growing rat, growth, food intake, FER and PER value, excretion of urinary arid fecal nitrogen and glucose and the level of glucose and cholesterol in serum blood was studied. Forty males and same number of females of Albino rats weighing male $58{\pm}2g$, female$62{\pm}2g$ were divided into eight experimental group, five male and female in each and fed rice diet, rice supplemented with wheat and rice supplemented with barley diet for 14 weeks. Under this condition wheat supplemented diet group shows the best FER, PER and body weight gain value. Especially in female group shows better FER, PER and body weight gain value compare to control diet group. Under the male groups wheat supplemented diet group shows lower FER, PER value and body weight compare to the control group but higher than those of barley diet group or rice alone. In female group the nitrogen retention shows also highest value by wheat supplemented diet group. By male group the wheat supplemented diet group shows not better value compare to the control group, but higer than barley supplemented group or rice alone. The nitrogen excretion through feces was significantly higher by grain supplemented diet group compare to grain the 20% sugar casein diet. The blood cholesterol content was slightly decreased by the control group which was fed disaccaride, compare to groups which were fed polysaccaride. But the free cholesterol to esterified cholesterol ratio shows lower value by control group than grain groups except the 70% rice supplemented with 30% barley group.

  • In this study, we aimed to increase the utilization of non-commercializable peach fruits collected during harvesting and distribution and to promote the transition of a high value-added industry. After producing pastes from the flesh of different peach varieties, we used these pastes as ingredients in the production of Kochujang. We then performed a comparative analysis on the quality characteristics of the peach-added Kochujang and commercially available Kochujang products. Peach-added Kochujang exhibited a lower pH and reduced sugar, salinity, reducing sugar, ash, and calorie content than those of commercially available Kochujang products. However, the Kochujang had slightly higher pH and moisture content than commercially available products due to high organic acid and moisture contents of peach flesh. In terms of content of inorganic elements, commercial Kochujang products exhibited higher sodium and magnesium content, whereas peach-added Kochujang had higher potassium content. In particular, the lower sodium and higher potassium content of peach-added Kochujang indicates that this product could be used as a functional food to prevent various diseases caused by excessive sodium intake among Koreans. After comparing the products in terms of phenol and flavonoid content, we concluded that ethanol extracts of peach-added Kochujang showed higher phenol content than those of the commercially available Kochujang products. In contrast, the distilled water extracts of peach Kochujang showed higher DPPH free radical scavenging activity than that of commercially available Kochujang products.

  • A number of studies have been conducted to confirm the preventive effect of xylitol on dental caries as a whole or partial alternative to dietary sugars. This study reviewed the oral health effects of xylitol on the prevention mechanism of dental caries, the prevention of dental caries, the inhibition of mother-to-child transmission, and the oral health effects in the elderly based on existing studies on the oral health of xylitol. Carbohydrates and dietary sugars in food are fermented by acid-producing microorganisms in the mouth and produce dental plaque and acid, which cause dental caries. However, most dental decay-causing bacteria cannot produce acids by metabolizing xylitol. Xylitol, stored in cells as a non-metabolizable metabolite by Streptococcus mutans (S. mutans), affects bacterial glucose metabolism and inhibits bacterial growth. Xylitol consumption also reduces the amount of plaque and the population of S. mutans in both plaque and saliva. In addition, xylitol acts in the remineralization process. Xylitol has been confirmed to effectively prevent dental caries, inhibit mother-to-child transmission of MS, prevent dental caries, and increase salivary flow in the elderly. In conclusion, xylitol is an adequate sugar substitute for dental health, from infants to the elderly. For future studies, the researchers recommend reviewing the effects of xylitol on the oral and intestinal microbial environment and the side effects of excessive intake.

  • To evaluate the effect of fiber sources on chewing activity, five sheep were consecutively fed diets containing 45% of a fiber source selected from 7 tested fiber sources of alfalfa hay cube(AHC), corn cob (CC), corn silage(CS), cotton seed hull(CSH), peanut hull(PHL), rice straw(RS) and sugarcane bagasse (SCB). Number of chew showed significantly higher value in CC(p<0.001) then other sources. RS and CC had highest(p<0.01) rumination times of 352 and 367 min/d, respectively. CC also showed the highest number of chew per kg NDF intake(p<0.01), but rumination time per kg NDF intake showed no difference except CSH(p<0.001). These results suggest that chewing activities were greatly affected by the fiber sources, and therefore it should be accounted in the formulation for ruminant feed.

  • This study evaluated the nutrition intake and changes in laboratory data of surgery patients with hypermetabolic severity on nutrition support. From January 2002 to September 2002, 66 hospitalized surgery patients who had received enteral nutrition (EN, n=19) and total parenteral nutrition (TPN, n=47) for more than 7 days were prospectively and retrospectively recruited. The laboratory data was examined pre-operatively, and on the post-operative 1, 3, 7 day and at the time of discharge. The characteristics of the patients were examined for the hypermetabolic severity, The hypermetabolic scores were determined by high fever ($>38^{\circ}C$), rapid breathing (>30 breaths/min), rapid pulse rate (>100 beats/min) , leukocytosis ($WBC>12,000/{\mu}l$), leukocytopenia ($WBC>3,000/{\mu}l$), status of infection, inflammatory bowel disease, surgery and trauma. The scores for the hypermetabolic status were divided into three groups (mild 0-10, moderate 11-40, severe>41). According to the results of the study, 38.3% (n=23), 45.4% (n=30) and 19.6% (n=13) were in the mild, moderate, and severe groups, respectively. There was a decrease in the serum albumin level and weight loss according to the hypermetabolic severity. However, the white blood cells (WBC), fasting blood sugar (FBS), c-reactive protein (CRP), total bilirubin, GOT, and GPT increased. The nutritional intake was TPN (32.5 kcal/kg, protein 1.2 g/kg, fat 0.25 g/kg), EN (28.1 kcal/kg, protein 1.0 g/kg, fat 1.01 g/kg). The serum albumin, hemoglobin and cholesterol were higher in the EN group than in the TPN group. But the FBS, total bilirubin, GOT and GPT were higher in the TPN group than the EN group. In conclusion, there was a negative correlation between the changes in the laboratory data and the hypermetabolic severity. There was an increase in the number of metabolic complications in the TPN group.

  • Two digestion trials, one with sheep and another with goats, were conducted to evaluate the long-term bias (LTB) of the indigestible dry matter (iDM), indigestible neutral detergent fiber (iNDF) and indigestible acid detergent fiber (iADF) internal markers. The study used eight Santa In$\hat{e}$s castrated male sheep (average body weight of 16.6 kg) distributed in two $4{\times}4$ Latin squares and eight Saanen castrated male goats (average body weight of 22.6 kg) distributed in two $4{\times}4$ Latin squares. The experiments were conducted simultaneously, and the animals were housed in 1.2 $m^2$ individual pens with wood-battened floors equipped with individual feeders and drinkers. The animals received isonitrogenous diets that were offered ad libitum and contained 14% crude protein and 70% sugar cane (with 0, 0.75, 1.5 or 2.25% CaO, in natural matter percentage), corrected with 1% urea and 30% concentrate. The experiment consisted of four experimental periods of 14 d each, with the feed, leftovers and feces sampled on the last four days of each period. The marker concentrations in the feed, leftovers and fecal samples were estimated by an in situ ruminal incubation procedure with a duration 240 h. The relationship between the intake and excretion of the markers was obtained by adjusting a simple linear regression model, independently from the treatment (diets) fixed effects and Latin squares. For both the sheep and goats, a complete recovery of the iDM and iNDF markers was observed (p>0.05), indicating the absence of LTB for these markers. However, the iADF was not completely recovered, exhibiting an LTB of -9.12% (p<0.05) in the sheep evaluation and -3.02% (p<0.05) in the goat evaluation.

  • Both metabolic syndrome (MetS) and elevated LDL cholesterol (LDL-C) increase the risk for cardiovascular disease (CVD). We hypothesized that low HDL cholesterol (HDL-C) would further increase CVD risk in women having both conditions. To assess this, we recruited 89 women with MetS (25-72 y) and LDL-C ${\geq}$ 2.6 mmol/L. To determine whether plasma HDL-C concentrations were associated with dietary components, circulating atherogenic particles, and other risk factors for CVD, we divided the subjects into two groups: high HDL-C (H-HDL) (${\geq}$ 1.3 mmol/L, n=32) and low HDL-C (L-HDL) (< 1.3 mmol/L, n=57). Plasma lipids, insulin, adiponectin, apolipoproteins, oxidized LDL, Lipoprotein(a), and lipoprotein size and subfractions were measured, and 3-d dietary records were used to assess macronutrient intake. Women with L-HDL had higher sugar intake and glycemic load (P< 0.05), higher plasma insulin (P< 0.01), lower adiponectin (P< 0.05), and higher numbers of atherogenic lipoproteins such as large VLDL (P < 0.01) and small LDL (P<0.001) than the H-HDL group. Women with L-HDL also had larger VLDL and both smaller LDL and HDL particle diameters (P<0.001). HDL-C was positively correlated with LDL size (r=0.691, P<0.0001) and HDL size (r=0.606, P<0.001), and inversely correlated with VLDL size (r=-0.327, P<0.01). We concluded that L-HDL could be used as a marker for increased numbers of circulating atherogenic lipoproteins as well as increased insulin resistance in women who are already at risk for CVD.

  • BACKGROUND/OBJECTIVES: Easy access to intervention and support for certain behaviors is important for obesity prevention and management. The available technology such as smartphone applications can be used for intervention regarding healthy food choices for obesity prevention and management in elementary-school students. The transtheoretical model (TTM) is comprised of stages and processes of change and can be adopted to tailored education for behavioral change. This study aims to develop TTM-based nutrition contents for mobile applications intended to change eating behaviors related to weight gain in young children. SUBJECTS/METHODS: A synthesized algorithm for tailored nutrition messages was developed according to the intake status of six food groups (vegetables, fruits, sugar-sweetened beverages, fast food and instant food, snacks, and late-night snacks), decision to make dietary behavioral changes, and self-confidence in dietary behavioral changes. The messages in this study were developed from December 2014 to April 2015. After the validity evaluation of the contents through expert consultation, tailored nutrition information messages and educational contents were developed based on the TTM. RESULTS: Based on the TTM, stages of subjects are determined by their current intake status, decision to make dietary behavioral changes, and self-confidence in dietary behavioral changes. Three versions of tailored nutrition messages at each TTM stage were developed so as to not send the same messages for three weeks at most, and visual materials such as figures and tables were developed to provide additional nutritional information. Finally, 3,276 tailored nutrition messages and 60 nutrition contents for applications were developed. CONCLUSIONS: Smartphone applications may be an innovative medium to deliver interventions for eating behavior changes directly to individuals with favorable cost-effectiveness. In addition, using the TTM for tailored nutrition education for healthy eating is an effective approach.

  • This study analyzed the physiological effects of silkworms and silkworm pupae on the reduction of serum lipid levels. Research data specific to silkworms and their pupae published over the last 10 years were collected and analyzed. A large effect size of 0.852 was observed in the overall results and the range of 95% confidence intervals was 0.662 to 0.999. The Q value was 23.264, the Higgin's I2 value was 92.217, indicating that each study was heterogeneous. There was no publication bias, as the corrected observed number of statistically significant effect sizes and the expected number of statistically significant effect sizes were both 0.654. The silkworm study showed a large effect size with respect to blood sugar and blood lipid reduction at 0.801 and 0.948, respectively, and LDL-cholesterol reduction at 1.371, showing a very large effect size. Aspartate transaminase / glutamic oxaloacetic transaminase (AST/GOT) was 0.768, alanine transaminase /glutamate-pyruvate transaminase (ALT/GPT) was 0.788, which was a medium effect size. The experiment period had a very large effect size of 1.170 for five to eight weeks and 1.020 for an intake of 1 to 50 mg/kg. The silkworm pupae had a large effect size of 0.991 and 0.951, respectively on blood lipids and total cholesterol reduction. The experimental period showed a very large effect size at 1.103 for more than nine weeks, and the intake showed a large effect size at 0.855 for 5001 mg/kg.

  • Objectives : It surveyed the recognition level of oral health in class teachers who have influence of students' oral health knowledges and behaviors in our country, developed a program available for supplementing reinforcement in school oral health education, and planned the knowledge contents necessary for school oral health education hereafter. Methods : To arrange the basic data necessary for school oral health program, it carried out questionnaire survey by personal self-administration targeting 460 teachers for 19 elementary schools where are located in Jinhae city from May 7, 2007 to June 13. The following conclusions were obtained. Results : 1. The path of acquiring oral health knowledge was shown the high frequency with 23.9% and 23.3%, respectively, through publicity brochure and dental clinic. As for the opinion about the aim of maintaining dental hygiene, the prevention of dental caries was the highest with 53.7%. 2. The opinion about which the regular visit to the dentist is very effective for preventing dental caries accounted for 56.7%. The opinions about which the limit to sugar intake and the use of dental floss are effective for preventing dental caries accounted for 52.2% and 46.3%, respectively. 3. The opinion about which the fluoridation beverage intake and the sealant are effective for preventing dental caries accounted for 33.9% and 33.0%, respectively. 4. The opinion about which the regular toothbrushing without toothpaste has a little effect and has no effect on preventing dental caries accounted for 42.6% and 38.5%, respectively. Conclusions : The elementary-school age period, which is the most core field out of the whole oral health, is the important period that is formed the basis of lifelong oral health care. It surveyed the recognition level of oral health in class teachers who are in charge of direct health care while making continuous life with students, and developed program available for supplementing reinforcement in school oral health education. Through this, there will be necessity for cultivating ability available for properly managing oral health for the whole life by allowing elementary-school students, who will be led to future adults' oral health, to be formed the attitudes toward the rationally oral health care.
