  • Studies were carried out to report breeding procedure and characteristics of Fb, a strain of silkworm with abnormal food habit polyphagous. Selection was continued up to the 14th generation toward higher incidence of cabbage leaves feeding variants. In the autumn of 1992(7th generation), selected strain were subjected to severe selection by feeding them on artificial diet that did not contain mulberry leaf powder. The results were clearly positive and reached to higher than 95% of cabbage feeding in the 14th generation. This strain was first discovered by feeding cabbage leaves, but later they were observed to eat some kind of plants like lettuce, Chinese cabbage, radish, beet, apple, persimmon, pear, etc. As described above the procedure, cabbage feeding trait was clearly heritable. The strain responsible for this traits was named Fb.

  • Objective: The aim of the present study was to investigate the effect of yeast with bacteriocin and Lactobacillus cultures (mixture of Lactobacillus agilis BCRC 10436 and Lactobacillus reuteri BCRC 17476) supplements, alone or in combination, on broiler chicken performance. Methods: A total of 300, 1-d-old healthy broiler chickens were randomly divided into five treatment groups: i) basal diet (control), ii) basal diet+0.25% yeast (Saccharomyces cerevisiae) (YC), iii) basal diet+0.25% yeast with bacteriocin (BA), iv) basal diet+Lactobacillus cultures (LAB), and v) basal diet +0.25% yeast with bacteriocin+Lactobacillus cultures (BA+LAB). Growth performance, cecal microbiota, cecal fermentation products, and blood biochemistry parameters were determined when chickens were 21 and 35 d old. Results: The supplementation of YC, BA, and BA+LAB resulted in a significantly better feed conversion rate (FCR) than that of the control group during 1 to 21 d (p<0.05). The LAB supplementation had a significant effect on the presence of Lactobacillus in the ceca at 35 d. None of the supplements had an effect on relative numbers of L. agilis and L. reuter at 21 d, but the BA supplementation resulted in the decrease of both Lactobacillus strains at 35 d. The BA+LAB supplementation resulted in higher short chain fatty acid (SCFA) in the ceca, but LAB supplementation significantly decreased the SCFA at 35 d (p<0.05). All treatments tended to decrease ammonia concentration in the ceca at 21 d, especially in the LAB treatment group. The BA supplementation alone decreased the triacylglycerol (TG) concentration significantly at 21 d (p<0.05), but the synergistic effect of BA and LAB supplementation was required to reduce the TG concentration at 35 d. The YC supplementation tended to increase the plasma cholesterol at 21 d and 35 d. However, the BA supplementation significantly decreased the cholesterol and low density lipoprotein cholesterol level at 35 d. In conclusion, the BA+LAB supplementation was beneficial to body weight gain and FCR of broiler chickens. Conclusion: The effect of BA and LAB supplementation may be a result of the growth of lactic acid bacteria enhancement and physiological characterization of bacteriocin, and it suggests that the BA and LAB supplementation level or Lactobacillus strain selection should be integrated in future supplementation designs.

  • We examined the effect of dietary behavior improvement on diet quality, body composition and blood lipid profiles in 68 middle-aged women. Dietary behavior intervention was consisted of counselling in the problem areas of portion control, food selection for low carbohydrate and high fiber food items, and education on the improvement of micronutrient intakes and diet quality. The subjects were divided into two groups; Improved or Not-Improved Group according to the level of changes in dietary behavior scores. After 6 months, body weight, BMI, waist-hip ratio, and visceral fat area were significantly decreased in the Improved Group compared to the Not-Improved Group. Calorie-adjusted protein, fiber, calcium, iron and vitamin C intakes were significantly increased in the Improved Group. The index of nutritional quality (INQ) and mean adequacy ratio (MAR) were increased only in the Improved Group. We observed a significantly increase in HDL-cholesterol and a decrease in total cholesterol, triglyceride and LDL-cholesterol, and an improvement of atherogenic index in the Improved Group. These results showed that dietary behavior intervention improved dietary behavior scores, and those whose dietary behavior score improved showed more improvement in diet quality, body composition, and serum profiles than those whose dietary behavior score did not improve.

  • Purpose : This study explores unmet medical services within a region for patients admitted to a single medical institution in one region and was to analyze the importance and satisfaction of hospital selection attributes. Through this, we tried to solve the unmet medical needs of patients and provide useful basic data in terms of hospital management in the region. Methods : It were collected to a total of 250 questionnaires for patients admitted to the regional integrative medical hospital. However, 232 samples were used for the final analysis, excluding 18 copies not reported in good faith. For the analysis, first, demographic frequency analysis of inpatients and inpatients was performed, and second, characteristics of patients, including frequent disease receiving treatment, were analyzed. Next, descriptive statistics analysis was conducted on unmet medical service intentions. In terms of hospital selection attribute, the items of continuity maintenance (I quadrant), priority visibility (II quadrant), low priority (III quadrant), and excessive effort (IV quadrant) were derived using the IPA (importance-performance analysis) matrix technique. Results : The derived results were classified by item and area. In the priority administration area, it was the reputation and recognition of medical institutions and the service area of medical institutions. In the case of items, there were 6 items including the importance of surgery and medical expenses, and diet at hospitalization. 1) Conclusion : Thus a result of this study, resources are efficiently allocated to priority correction areas with high importance but low satisfaction and circulatory medical treatment is performed in the departments required by patients who use medical care and, various methods, such as preparing a policy to support medical expenses, should be sought.

  • This study examined the factors that affect the relationship between single-person households, food related life style, restaurant selection attributes, and behavioral intention. In order to perform statistical analyses required in the study, SPSS 18.0 Statistical Program was employed for frequency analysis, factor analysis, reliability analysis, correlations, and regression analysis. The results of exploratory factor analysis showed that four factors regarding food related life style were extracted from all measurements with a KMO of 0.716 and a total cumulative variance of 64.437%, With regard to restaurant selection attributes, one factor was extracted with a total cumulative variance of 75.372% and a KMO score of 0.739. One factor for behavioral intention was extracted that accounted for a total cumulative variance of 61.312% and a KMO score of 0.666. All factors were significant to .000 and the correlation between variables was significant. Thus, based on the results, the main research hypotheses regarding the relationships among food related life style restaurant selection attributes, and behavioral intention were adopted.

  • Since diet is an essential component of the treatment for diabetic mellitus, a progressive educational plan was designed to educate diabetic children for the proper selection of their foods. Seven suspicious children were chosen according to the previous oral glucose tolerance test and present blood glucose levels (fasting and postprandial 2 hours). The education program includes the basic nutrition study, learning of the five basic food groups. familiarization with the food exchange lists. calorie calculation and menu planning, and follow-up evaluation by checking every day -food intake. The duration of the education was five weeks. The levels of fasting blood glucose and postprandial -2 hours blood sugar of the seven children were significantly reduced after the 5-weeks education:FBS:from 92-125mg% to 67-80mg%, pp-2hours BS: from 130-169mg% to 69-90mg%. The children have felt much better with profound self-confidence after to program . Their oral glucose tolerance test levels were also significantly decreased after the 5-weeks education in comparison with those of one year ago.

  • Genetic selection and sophisticated management technology have produced modern sows which excel in litter size and milk production. Recent research has identified nutritional innovations which may enhance productivity of the high producing sow. Selected research in three areas which have the potential to enhance reproductive performance are summarized in this report. First, preliminary evidence indicates that organic chromium may enhance litter size and conception rate. Secondly, high producing sows, particularly primiparous sows, required higher protein/lysine in late gestation and or lactation to optimize weaning weight and subsequent litter size. Valine and isoleucine, but not leucine, have been shown to enhance milk production. Phased feeding programs with diet cost partitioned toward gilts and away form parity 3 to 8 sows have been suggested as a means of improving reproductive performance in young sows. Lastly, recent research with sufficient sow numbers to document the effect of dietary fiber on reproductive performance has shown that sows fed fiber farrowed and weaned more pigs.

  • There is growing interest for improving meat quality in chicken. Recently, the proteomics can be used as a valuable tool for identifying candidate proteins. In this study, we investigated the proteins expressed in chicken muscle for obtaining chicken muscle reference two dimensional(2D) map and identifying the proteins in muscle affecting Ginseng diet. A few candidate proteins have been currently characterizing using MALDI-TOF Mass spectrometry. Further investigations of the proteins can be used as valuable markers for selection of better quality chicken meat.

  • Growing male rats were allowed to have food from two dishes containing isocaloric, isoprotein 15% or 70% carbohydrate diet for 4, 8, 12 or 24 hours a day at the beginning of the dark period. Four hours of feeding were not enough to grow though the first 4 hours of intake were significantly higher than other periods. 4-hour and 8-hour feeding groups consumed significantly less carbohydrate calorie than 12-hour and ad libitum feeding groups, which hence, showed lower ratio of carbohydrate to protein in the total food consumed. The fasting brain tryptophan and serotonin levels among groups were not significantly different. It appears therefore that the manipulation of the feeding period could be valuable in suppression of carbohydrate appetitie, especially carbohydrate carving.

  • Gustation, initiated by the detection of taste molecules by specific receptors expressed in taste cells, plays an essential role in food selection and consequently in overall nutrition for humans. In the past decade, a remarkable amount of knowledge of taste perception in the neurology, molecular biology, and genetics has emerged, particularly in basic tastes- sweet, bitter, sour, salt and umami. Among them, sweet, bitter and umami are recognized via the specific G-protein coupled receptors. Salt and sour are primarily mediated by apically located ion channel-type receptors. Because excessive salt or sugar consumption leads to high rates of diet-associated diseases and it comes from eating prepared or processed foods, an understanding of the underlying mechanisms in salt and sweet perception is crucial in food industry. This review will focus on recent progress of the perception of salt and sweet taste to provide basic knowledge for reducing salt and sugar consumption.
