The purpose of this study is to provide the basic information necessary to develop sports uniform design by comparing and analyzing the color features and images of professional football uniforms in Korea and foreign countries. The subjects of this study were limited to 5 top leagues in Europe (Premier League, Primera Liga, Bundesliga, Serie A, and Ligue 1) as well as J-League, and K-League. This study was done using the 2012/2013 season home and away uniforms for European leagues and 2013 season home and away uniforms for Korean and Japan leagues. Using the Adobe photoshop CS2 eyedropper tool, color chips and RGB values were extracted from digital images and converted into HV/C of Munsell Conversion. Finally, a total of 735 colors were used for the analysis. The color image scale by Shigenobu Kobayashi was used to position the color images. The results are as follows. First, the color analysis of professional football uniforms in leagues suggested that chromatic color (53.7%) was more prevalent than achromatic color (46.3%). The two most common colors of the ten chromatic colors were R(19.7%) and PB(18.0%), followed by Y(5.4%), RP(2.0%), G(1.9), GY(1.8%), B(1.6%), YR(1.5%), P(1.1%), and BG(0.7%). Second, for the color tone comparison and analysis of professional football uniforms in leagues, the most commonly used color tone was W(28.4%), followed by v(25.5%), Bk(16.3%), s(5.8%), dk(5.2%), b/lt(5.2%), dp(3.0%), sf(2.0%), ltGy(1.0%), p(0.5%), G/dkGy(0.4%), and ltg/mGy (0.1%). Third, for the comparison and analysis of color and color tone of professional football uniforms in leagues, W(28.4%), R(v)(17.7%), and Bk(16.3%) were commonly used. Finally, for the comparison and analysis of color images of professional football uniforms in leagues, the most commonly used color image was a casual image(31.8%), followed by modern image(26.5%), dynamic12.8%), cool casual(12.0%), gorgeous(9.3%), clear(6.6%), chic(3.5%), and elegant images. Dandy, classical, romantic and pretty images(0.4% respectively) were also used.

The effects of aerobic and vacuum packaging of fresh duck meat on meat qualities including color, cooking loss, shear force, lipid oxidation and fatty acid composition during cold storage were investigated. The result showed that pH of the samples were decreased as increasing storage time, and leg meat showed significantly (p<0.05) higher than breast meat. Redness showed significantly (p<0.05) higher value in breast meat compared to leg meat as increasing the storage time. However, TBARS value showed significantly (p<0.05) higher in breast meat compared to leg meat as increasing storage time. This result suggested that the lower pH affected lipid oxidation and discoloration of the meat samples. However, fatty acid composition of 1 day storage time showed that aerobic packaging of leg meat had lower (p<0.05) ratio of palmitic acid and higher (p<0.05) ratio of linoliec acid, whereas vacuum packaging of leg meat showed higher (p<0.05) ratio of palmitic acid at 7 days storage time than other treatments. Therefore, this data speculated that saturated fatty acid like palmitic acid and unsaturated fatty acid like linoleic acid were affected by lipid oxidation at different storage time. Finally, aerobic packaging meat accelerated lipid oxidation compared to vacuum packaging meat, hence self life was no longer better than vacuum packaging meat without relation of different type of meat from duck.

The chicken liver has been involved in various biological functions including detoxification, glycogen storage and plasma protein synthesis. The aim of this study was to investigate differentially expressed genes in chicken liver in four different growing stages. Using 10 arbitrary Annealing Control Primers (ACPs), five differentially expressed genes have been identified. Based on the Basic Local Alignment Search Tool (BLAST) search results, three of them were matched with previously known genes, and the other two were matched with unknown EST sequence and a hypothetical protein, respectively. In order to confirm the expression results, quantitative real-time PCR was also performed. The high similarities between the expression data using arbitrary ACPs and quantitative real-time PCR indicate that the identified genes are the real differentially expressed genes in different growing stages. The genes identified in this study can be used as valuable biomarkers in chicken with further investigation of the functions.

Backgroud. To determine the influence of age at operation upon surgical outcome in patients with isolated secundum atrial septal defect, retrospective clinical analysis was done. Material and method. From June, 1976 to December, 1991, 146 patients, 63 male and 83 female patients ranging in age from 13 months to 56 years, were operated on for isolated secundum atrial septal defect. The patients were divided into 3 groups according to their age at operation: Group I [<20 years old], 91 patients[62.3%]; Group II [21 to 40 years old], 44 patients[30.1%]; GroupIII[>41 years old], 11 patients[7.6%]. Significant differences in clinical features, hemodynamic function, early and late results between age groups were speculated. Results. One hundred thirty-one patients[89.6%] were symptomatic at the time of operation, the most common symptoms being dyspnea on exertion, recurrent respiratory infection, palpitation and chest pain. Patients in NYHA class III or IV were 3.3% in group I, 25% in groupIII, and 54.5% in group Ill. Hemodynamic data was available for 138 patients [94.5%]. Significant pulmonary hypertension [MPA systolic pressure $^3$ 40mmHg] was noted in 22 patients [15.9%]. Patients with pulmonary vascular disease [Rp/Rs>1.25] were 2% in group I, 7.3% in group Il, and 9.1% in groupIII. But there were no significant differences between the age groups in the size of the shunt or the ratio of pulmonary to systemic flow. Atrial septal defects were closed with direct suture in 144 patients and patch repair was performed in 2 patients with high defect. Atrial arrhythmia [8.2%] was the most common postoperative complication. The mean [LSD] duration of follow-up in all patients was 16$\pm$22 months [range, 1~96 months]. Functional result was excellent regardless of the age groups. During follow-up period, late cardiovascular events were arrhythmia [7 cases], reoperation for recurrent ASD [2 cases], and premature late death due to bacterial endocarditis [1 case]. Incidence of preoperative and late atrial fibrillation was significantly higher in older age group. Conclusion. Age at operation is one of the most important predictor of early and late surgical outcome with its impact on the following factors : 1] hemodynamic alterations and ventricular dysfunction due to longstanding volume and pressure overload, 2] pulmonary vascular disease, and 3] atrial arrhythmia including atrial fibrillation as a result of atrial dilatation. Therefore, among patients with surgically repaired atrial septal defects, those operated on over the age of 20 require careful supervision on the long-term basis.

An in vitro gas production technique was used in this study to elucidate the effect of two strains of active live yeast on methane ($CH_4$) production in the large intestinal content of pigs to provide an insight to whether active live yeast could suppress $CH_4$ production in the hindgut of pigs. Treatments used in this study include blank (no substrate and no live yeast cells), control (no live yeast cells) and yeast (YST) supplementation groups (supplemented with live yeast cells, YST1 or YST2). The yeast cultures contained $1.8{\times}10^{10}$ cells per g, which were added at the rates of 0.2 mg and 0.4 mg per ml of the fermented inoculum. Large intestinal contents were collected from 2 Duroc${\times}$Landrace${\times}$Yorkshire pigs, mixed with a phosphate buffer (1:2), and incubated anaerobically at $39^{\circ}C$ for 24 h using 500 mg substrate (dry matter (DM) basis). Total gas and $CH_4$ production decreased (p<0.05) with supplementation of yeast. The methane production reduction potential (MRP) was calculated by assuming net methane concentration for the control as 100%. The MRP of yeast 2 was more than 25%. Compared with the control group, in vitro DM digestibility (IVDMD) and total volatile fatty acids (VFA) concentration increased (p<0.05) in 0.4 mg/ml YST1 and 0.2 mg/ml YST2 supplementation groups. Proportion of propionate, butyrate and valerate increased (p<0.05), but that of acetate decreased (p<0.05), which led to a decreased (p<0.05) acetate: propionate (A: P) ratio in the both YST2 treatments and the 0.4 mg/ml YST 1 supplementation groups. Hydrogen recovery decreased (p<0.05) with yeast supplementation. Quantity of methanogenic archaea per milliliter of inoculum decreased (p<0.05) with yeast supplementation after 24 h of incubation. Our results suggest that live yeast cells suppressed in vitro $CH_4$ production when inoculated into the large intestinal contents of pigs and shifted the fermentation pattern to favor propionate production together with an increased population of acetogenic bacteria, both of which serve as a competitive pathway for the available H2 resulting in the reduction of methanogenic archaea.

Background: Methyl donor status influences DNA stability and DNA methylation although little is known about effects on DNA methyltransferases. The aim of this study was to determine whether methyl-donor status influences DNA methyltransferase (Dnmt) gene expression in cervical cancer cells, and if so, whether there are associated effects on global DNA methylation. Materials and Methods: The human cervical cancer cell line, C4-II, was grown in complete medium and medium depleted of folate (F-M+) and folate and methionine (F-M-). Growth rate, intracellular folate, intracellular methionine and homocysteine in the extracellular medium were measured to validate the cancer cell model of methyl donor depletion. Dnmt expression was measured by qRT-PCR using relative quantification and global DNA methylation was measured using a flow cytometric method. Results: Intracellular folate and methionine concentrations were significantly reduced after growth in depleted media. Growth rate was also reduced in response to methyl donor depletion. Extracellular homocysteine was raised compared with controls, indicating disturbance to the methyl cycle. Combined folate and methionine depletion led to a significant down-regulation of Dnmt3a and Dnmt3b; this was associated with an 18% reduction in global DNA methylation compared with controls. Effects of folate and methionine depletion on Dnmt3a and 3b expression were reversed by transferring depleted cells to complete medium. Conclusions: Methyl donor status can evidently influence expression of Dnmts in cervical cancer cells, which is associated with DNA global hypomethylation. Effects on Dnmt expression are reversible, suggesting reversible modulating effects of dietary methyl donor intake on gene expression, which may be relevant for cancer progression.

1,225 healthy day-old avian broiler chicks were used to investigate the effects of activated charcoal (AC, made from willow tree), hydrated sodium calcium aluminosilicates (HSCAS) and esterified glucomannan (EGM) supplementation on broiler performance, blood profiles and meat characteristics when less moldy or moldy corn was included to formulate seven isocaloric and isonitrogenous diets: Positive Control (less moldy corn diet, PC), PC+2% AC, Negative Control (moldy corn, NC), NC+0.05% EGM, NC+0.1% EGM, NC+0.5% HSCAS and NC+1% AC. PC+2% AC resulted in lower growth rate, poorer feed conversion ratio (FCR), more leg problems and higher mortality of birds than those fed PC diet (p<0.05). Inclusion of 0.05% EGM, 0.1% EGM, 0.5% HSCAS and 1% AC in NC diet did not improve average daily weight gain (ADG) or affect feed intake of birds during the first or the second three-week periods. However, 0.05% EGM tended to (p>0.05) and 0.1% EGM significantly (p<0.05) improved FCR during the first three-week period. Breast meat of NC birds had higher Minolta $L^*$ values (white) but lower $a^*$ (reddish) and $b^*$ (yellowish) values (p<0.01) than the PC birds. Addition of 0.05% EGM and 0.1% EGM in NC diet reduced the $L^*$ values (p<0.05), improved $a^*$ and $b^*$ values (p<0.05) of breast meat of birds fed NC diet, but had no effect on meat color when 0.5% HSCAS or 1% AC was included (p>0.05). Relative weight of liver to body was reduced by feeding NC diet (p<0.05) and could not be normalized by different mycotoxin adsorbents (p>0.05) to the ratio of the PC birds. Relative weight of cholecyst of NC birds was increased compared with PC birds and could only be normalized by addition of 0.05% EGM and 1% AC (p<0.05) in NC diet. NC birds had lower serum albumin level than the PC birds (p<0.05) and addition of 0.05% EGM or 1% AC in NC diet did normalize serum albumin level. Addition of 0.5% HSCAS in NC diet further reduced serum albumin, globulin, total protein and uric acid levels (p<0.05). It was concluded that lower FCR during the first three-week period of growth and deterioration of meat quality observed in bird fed moldy corn with moderate T2 and fuminisin contamination and damaged nutrients and pigment availability, might be improved by dietary supplementation of 0.05% to 0.1% EGM, but not by 1% AC or 0.5% HSCAS supplementation.

This study was performed to assess diet qualities by sexes and ages of adults over thirty years old in Jeon-ju area. Diet survey with one day 24-recall method was used done for 382 subjects(129 males & 253 females). Survey sample was divided into six groups by sex and age groups: male 30-49, male 50-64, male 50-64, male 65-79, female 30-49, female 50-64 and female 65-79 years. Diet quality was assessed by NAR(Nutrient Adequacy Ratio), MAR(Mean Adequacy Ratio), INQ(Index of nutrition quality), KDDS(Koreans Dietary Diversity Score), Meal Balance, DVS(Dietary Variety Score), DQI(Diet Quality Index). The 5-point DQI assessed the important dietary guidelines for Koreans. The averages of energy, protein, P, vitamin B$_1$, vitamin B$_2$, niacin and vitamin C intakes were higher than 70% of RDA. The averages intakes of Ca and vitamin A were very lower than RDA all groups. The averages of MAR were 0.78, 0.81, 0.83 in male 30-49, 50-64, 64-79 years, 0.73, 0.77, 0.71 and in female 30-49, 50-64, 65-79 years, respectively. The averages of MAR in female 30-49 years and female 65-79 years were significantly lower than the averages MAR of male 65-79 years. The averages of Sugars and Beverages intakes were significantly higher in male 30-49 years than others. Animal food intake ratio(% total food intake) in the male 65-79 years(16%) was significantly higher than male 30-49 years(11%). The averages of Nutrition intakes were higher in male compared to female. The subjects who consumed all of the major five food groups were 5% in male 30-49, 17.8% in male 50-64, 25.0% in male 65-79 years, 18.9% in female 30-49, 23.7% in female 50-64, 11.5% in female 65-79 years. The averages of KDDS were 3.5, 3.9, 3.9, 3.8, 3.8, 3.5, respectively. The averages of Meal Balance were 8.6, 9.1, 9.1, 8.3, 8.4, 7.8, respectively. The averages of DVS 20.1, 19.9, 19.9, 20.5, 19.0, 17.2, respectively. The averages of DQI were 1.7, 2.2, 2.1, 2.0, 2.1, 1.7, respectively. 81.8% of the subjects had KDDS scores of 2 to 4 and 87.3% of the subjects has Meal Balance scores 4 to 10. In contrast, 89.8% of the subjects had DQI scores of 0 to 3. In view of these facts there are few who observed the five dietary guidelines for Koreans. There findings suggest that dietary qualities were associated with nutrient intake the relation factors may vary by sex and age of adults over thirty years old in Jeon-ju area. Common problems were lack of Ca, vitamin A and dairy products intakes. Therefore adults over thirty years old in Jeon-ju area need the important nutrient management such as Ca, vitamin A.

In Korea, Brassica species planted in summer remain in rosette and do not flower. Seed production of vernalized rape seedlings grown in summer was evaluated to establish method of generation shortening and genetically pure seed production without isolation of seed fields. When vernalized rape seedlings of different maturity groups were transplanted in summer, all plants bolted and flowered, and average days from sowing to bolting and flowering was 37 and 58. respectively. It took 85days for early maturity group, 88 days for medium maturity group, and 108 days for late maturity group to mature. Seed yield of vernalized plants grown in summer was 8.8 gr per plant and 53kg per l0a which was 23% of seed yield of rape planted in autumn. However, enough seeds were produced to test oil composition and cake and to plant for a next generation. If seedlings are raised, they can be transplanted in more than 1, 000 times of original seed field, indicating that genetically pure seed can be produced without caging seed fields with nets and isolation of seed fields since other Brassica species do not flower in summer.

The effects of probiotic-vitacogen and galacto-oligosaccharides (GOS) supplementation on methanogesis, energy and nitrogen utilization in replacement dairy cows were evaluated. A basal diet comprising orchardgrass hay, lucerne hay cube and concentrate (2:2:1, DM basis) were fed with or without supplements to four cows at $80g\;DM/kgBW^{0.75}$per day in a $4{\times}4$ Latin square arrangement. The four treatments were; 1) basal diet, 2) basal diet plus 100 g probiotic-vitacogen, 3) basal diet plus 50 g GOS, 4) basal diet plus 50 g GOS and 100 g probiotic-vitacogen. Nutrient apparent digestibility was not altered by the effect of supplementation. Nitrogen intake was significantly (p<0.001) higher for the two vitacogen-supplemented diets compared to control and GOS supplemented diets. However, vitacogen supplemented diets had numerically higher fecal and urinary nitrogen losses, thereby, having lower nitrogen retention compared to control and GOS supplemented diets. Gross energy intake was also significantly (p<0.05) higher for vitacogen-supplemented diets compared to control and GOS diets, however, due to higher losses in feces, urine, methane and heat, GOS supplemented diet had numerically higher energy retention. There was an 11% reduction in methane emission (liters/day) in GOS supplemented diet compared to control diet. However, the combination of GOS with vitacogen resulted in an increased methane emission. When expressed per unit of animal production (g/kg live-weight gain), methane production tended to be lower in vitacogensupplemented diets compared to control and GOS diets. The supplementation of replacement dairy cows with GOS reduced methane emission (liters/day), while, vitacogen supplementation reduced methane emission per unit animal production. The two feed supplements may contribute to the abatement of methane as a greenhouse gas.
