Human breast milk is a potential source of bacteria for the development of the intestinal microbiota of infants. Several species within the genera Lactobacillus and Bifidobacterium were demonstrated to shape the gut microbiota of infants. In this study, the bacterial diversity was investigated in the breast milk and feces of a mother-infant pair, and probiotic candidates were identified. Importantly, the novel L. gasseri EJL and B. breve JTL strains were isolated from breast milk and infant feces samples, respectively; their completed genome was resolved using de novo sequencing. In addition, the bacterial composition in the infant's feces at 1 week revealed the prevalence of Bifidobacterium and Streptococcus; a higher diversity was observed after 3 weeks. In particular, the abundance of Akkermansia was sharply increased at 7 weeks, further increasing thereafter, up to 15 weeks. Our results suggest that human breast milk and infant's feces are a source of probiotic candidates.

The average glandular dose (AGD) is determined by the breast entrance skin exposure, x-ray tube target material, beam quality (half-value layer), breast thickness, and breast composition. Almost breast cancer always arises in glandular breast tissue. As a result, the average radiation absorbed dose to glandular tissue is the preferred measure of the radiation risk associated with mammography. If the normalized average glandular dose is known, the average glandular dose can be computed from the product of the normalized average glandular dose and breast entrance skin exposure. In this study, AGD was calculated by the breast thickness and various x-ray energy (HVL) in 50% glandular 50% adipose breast by Mo.-Rh. assembly. AGD is 84 mrad in compressed 5 cm breast. These results show that as increasing the breast thickness, dose also increases. But as increasing the x-ray tube voltage, dose decreases because of high penetrating ratio through the object. But high tube voltage is reducing the subject contrast. From this result, we have to consider the trade-off between subject contrast of image and dose to the patient and choose proper x-ray energy range.

Fecal microflora of 12 breast-fed(BF) and 15 formula-fed(FF) infants were investigated at 1 year after birth and the results were compared to those that had previously been obtained from the same subjects at 1 week after birth, and before and after weaning. At 1 year the two lactation groups showed no significant differences both in frequencies and numbers of each major bacterical species, except eubacteria, which showed higher frequency in FF infants. Bifidobacteria appeared as dominant species in 50% BF infants, heres bacteroides in 73.3% FF infants. Fecal pH was lower, though insignificant, in BF infants(6.5$\pm$0.4) than in FF infants(6.8$\pm$0.5). In BF infants, the number of bifidobacteria, clostridia, and E. coli deceased from birth up to 1 year, whereas the number of bacteroides similar trends to BF infants except that the number of bifidobacteria increased, but insignificantly. This research showed that the floral differences resulted not from the age, but from the types of feeding and that breast feeding and that breast feeding could be better than formula feeding in the BF infants had more stable floral composition and bowels with lower pH, which can play a protection role against pathogen infection.

The purpose of this study is to suggest size specifications for the development of mastectomy bras and breast prostheses. To collect anthropometric data, 250 middle aged women's body measurement were taken and the data were analyzed by statistical methods such as ANOVA, correlation analysis, factor analysis and cluster analysis. The results of the analysis of measurement data showed that lengths. breadths, depths, circumferences are increased significantly when getting older. The results of the correlation analysis showed that there was no direct linear relationship between chest circumference and cup size. From 29 measurements, 4 factors were selected as key factors by the tractor analysis and the breast type were classified into 2 groups by cluster analysis. To set up sizing systems for the mastectomy brassiere, chest circumference and cup size were selected and the loss function was used to decide Intervals of each of them. 6 sizes from chest circumference and 4 sizes from cup sizes were picked, Breast breadth, breast length and breast height were chosen to establish sizing systems for the breast prosthesis. To decide intervals of each of them, the loss function was used and 8 sizes from composition of the 3 factors were picked.

To compare the dietary intakes and body composition in the stage of puberty, this study was conducted with 360 girls aged 9 to 12 years in Seoul Korea. Girls's general information and 3-day diet records were collected, fat mass was measured by Inbody 3.0, bone mass at right calcaneus was measured by PIXI and pubertal development was self-assessed by picture of Tanner stages. The results are as follows: Girls who had breast development were 79.7% and 15.8% had pubic hair development. Mean of BMI, BMC and BMD were significantly higher at breast stage3+(19.6 kg/$m^2$, 1.62 kg, 0.47 g/$\textrm{cm}^2$) than at the breast stage2 (18.2 kg/$m^2$, 1.47 kg, 0.44 g/$\textrm{cm}^2$) or breast stage1(16.3 kg/$m^2$, 1.32 kg, 0.39 g/$\textrm{cm}^2$) (p < 0.001). Percent body fat of breast stage1, 2, and 3+ were 19.7%, 23.1%, 25.3% respectively and significantly increased during the puberty (p < 0.001). The mean of energy intake was 1629 kcal in stage1, 1664 kcal in stage2 and 1577 kcal in stage3+ showed significant difference in the breast stages (p < 0.05). Energy adjusted sodium intakes and crude fiber intakes were significantly higher in breast stage3 + than other breast stages. For zinc and iron, proportions of subjects with intake levels less than 75% of Korean RDA was over 40% and significantly higher in breast stage3+ than other stages (p < 0.05) ; for protein and vitamin E, the proportions of subjects with intake levels more than 125% RDA was significantly higher in the stage 1. The nutrient adequacy ratio (NAR) for protein and phosphorous was significantly lower in breast stage3+ than other stages. The food groups of seed and nut were 4.7 g/day, 2.3 g/day, 1.8 g/day, respectively, and was significantly higher in breast stage 1. In summary, mean of BMI, BMD, BMC and percent of body fat were increased with pubertal development, and those who had higher breast developmental stage showed a lower amount of consumption level in energy, seeds and nuts, and also showed a higher amount of consumption level in energy adjusted sodium and fiber among Korean girls.

One- to three-month-old infants (n=232) were compared their upper arm cumference and skinfold thickness(triceps, subscapular) by feeding methods in cross-sectional study. There were two groups : breast-fed(BF) and formula-fed groups(FF). As reported previously, weight, length, head and chest circumferences of these infants were good, and overall growth status was not significantly different by feeding methods, but weight, weight velocity and chest circumference of formula-fed infants were higher than breast-feds at 3month, significantly. Hear, the triceps skinfold thickness of infants at 1, 2, and 3 postpartum months were 7.4, 9.5 and 10.5 mm, respectively. The triceps skinfold thickness of breast-fed infants were higher than formula-feds at 1 and 2 postpartum month, but at 3 month that of formula-fed infants was greater than breast-fed infants, insignificantly. The subscapular skinfold thickness of infants were 6.4, 9.2 and 10.6 mm at 1 to 3 postpartum months, respectively. The upper arm circumference of infants were 11.7, 13.4, 14.3cm, and the arm muscle diameter were 34.5,39.3 and 41.7cm at one to three postpartum months, respectively. The upper arm circumference of male infants was higher than females at 2, 3 postpartum months. Overall, there were no signifiant differences between feeding methods in triceps and subscapular skinfold thickness, upper arm circumference and arm muscle diameter. But 3-month-old formula-fed male infant showed bigger significantly in arm circumference than the breast-feds. From this survey, long-term survey on growth and body composition of large scales might be necessary to determine the effect of feeding methods of infants after 3 months and to set proper body composition standard for infant.

Experiments were conducted to evaluate the effect of an outdoor-grazed raising model on meat composition, physical properties and sensory attributes of Taiwan game hens. Six hundred 1-d old female chicks were raised on a floor for 8 weeks. On day 57, 600 healthy birds, with similar body weight, were selected and randomly assigned to three treatment groups (cage, floor-pen and free-range). The results showed that different feeding models had no effect on drip loss, cooking loss, moisture, crude protein, crude fat, crude ash, zinc and calorie contents in breast meat and moisture content in thigh meat. The free-range group had the lowest fat content in both breast and thigh meat, and the lowest calorie content in thigh meat. The firmness and toughness in both thigh and breast of the free-range group were the highest values (p<0.05). The crude protein, total collagen, zinc and iron contents in thigh meat and total collagen content in breast meat of the free-range group were significantly higher than those of the cage-feeding group (p<0.05). The meat sensory scores of flavor, chewiness and overall acceptability of both thigh and breast meat of the free-range group were significantly (p<0.05) better than those of the other two groups. Moreover, the current findings also indicate that the Taiwan game hens of the free-range feeding model displayed well-received carcass traits and meat quality, with higher scores for flavor, chewiness and overall acceptability for greater sensory satisfaction in both breast and thigh meat. In addition, the thigh meat contained high protein and total collage but low fat, offering a healthier diet choice.

The aim of this study is to evaluate the incidence of white striping abnormality and its consequences on the quality traits of raw and processed turkey breast (chemical composition, color traits, and water holding capacity). In total, about 2300 breasts from 22 flocks were used to assess the incidence and 60 breasts to evaluate the quality traits. Our study showed that the total incidence of moderate and severe white striping was 61.3% out of them, moderate cases were 49.4%. Severe white striped turkey breast exhibited significantly lower protein content (21.1 vs. 23.2 and 23.16%, p<0.05) and higher fat content (2.3 vs. 0.77 and 1.76%, p<0.05) if compared to normal and moderate white striped breast respectively. Moreover, moderate and severe white striped meat showed significantly higher redness (a*) (2.98 and 3.14 vs. 1.48, p<0.05) and yellowness (b*) indexes (7.27 and 7.95 vs. 4.05, p<0.05) than normal meat, respectively.

This experiment was conducted to evaluate the effects of dietary olive oil on growth performance, carcass parameters, serum characteristics, and fatty acid composition of breast and drumstick meat in broiler chickens. A total of 480 broilers were randomly allotted into three dietary treatments, including T (basal diet, 5% tallow), O1 (2% olive oil+3% tallow), and O2 (5% olive oil). During d 0 to 21, broilers fed the diet supplemented with 5% olive oil showed lower (p<0.05) body weight gain (BWG) and feed intake (FI) compared with those fed the T diet. Serum triglyceride concentration was reduced (p<0.05), while high density lipoprotein (HDL)-cholesterol concentration was increased (p<0.05) in the O2 treatment group compared with the T and O1 treatment groups. The addition of olive oil to the diets induced a reduction (p<0.05) in the total saturated fatty acid (SFA) contents in breast and drumstick meat, and increased (p<0.05) the total unsaturated fatty acid (USFA) contents and USFA/SFA ratios. In conclusion, a diet with 5% olive oil could decrease BWG and FI of broilers during the starter period (wk 0 to 3), and cause an increase in the serum HDL-cholesterol level, while decreasing the serum triglyceride concentration. Furthermore, USFA level and USFA/SFA ratios in breast and drumstick meat were increased by dietary supplementation of 2 or 5% olive oil.
