This study was intended to investigate food, exercise habits, perception of health status and the effects of nutrient intake of female college students. Food habits such as regularity of meal time, repast of breakfast, numbers of night snack per week and duration of meal were assessed via a self reporting questionnaire, and 24hrs recall method for nutrient intake was obtained from 155 female college students in Yangju-si. The mean height and weight of the subjects were $161.25{\pm}3.52cm$ and $52.26{\pm}4.52kg$, respectively. The average intakes of energy and nutrients were below the Korea recommended dietary allowance(RDA). Especially, The nutrient intakes(energy, protein, fat, fiber, calcium, iron, phosphorus, zinc, sodium, potassium, vitamin B6, niacin, vitamin C, folate, vitamin E, cholesterol) of the group in which the regularity of meal time per week was 5~7 days was significantly higher than the group in which the regularity of meal time was < 3 days (p<0.005). The nutrient intakes influenced by the food habit such as the regularity of meal time, skipping breakfast, and the numbers of night snack per week but did not differ in accordance with the regular exercise habits and perception of health status. These findings suggest that nutritional education based on female college students' food habits(regularity of meal time, skipping breakfast and night snacks per week, and duration of meal) may be required to improve dietary variety. It is considered that the improvement in dietary habits will contribute to the improvement of nutrition.
Sox4, a transcription factor, consists of three functional domains: an HMG-box domain as a DNA binding domain, serine rich region as a transactivation domain and glycine rich region (GRR), an unknown functional domain. Although Sox4 is known to be functionally involved in heart, B-cell and reproductive system development, its physiological function remains to be elucidated. We used pGEX expression system to develop a simple and rapid method for purifying Sox4 protein in suitable forms for biochemical studies of their functions. Unexpectedly, we observed that full-length Sox4 appears to be protease-sensitive during expression and purification in E. coli. To map the protease-sensitive site in Sox4, we generated various constructs with each of functional domains of Sox4 and purified as the GST-Sox4 fusion proteins using glutathione beads. We found that the specific cleavage site for the proteolytic enzyme, which exists in E. coli, is localized within the novel GRR of Sox4. Our study suggest that the GRR of Sox4 may a target for the cellular protease action and this cleavage in the GRR may be involved in regulating physiological function of Sox4. Additionally, our study may provide a useful method for investigating the proteolytic cleavage of the target molecule in E. coli.

In this study, we created grassland establishment(paddock No.39), grassland improvement(Paddock No.44), and tall fescue seeding(paddock No.64), and the rate botanical composition, DM yield, nutritive value were examined through 2016 to 2017. The rate of botanical composition was 81% in 2016, 75% in 2017, up to 21% higher than No.39 67%, 60%, No.44 58% and 54%. The annual average DM yield was the highest at 13,234kg/ha in the district, followed by No.39, No.44, followed by 10,636kg/ha and 10,235kg/ha, respectively. The crude protein content was the highest at No.39 12.16%, with No.44 and No.64 showing 10.7%, respectively. NDF content (average for two years) was 55.90% in No.44 and No.39, slightly lower than 58.42% and 57.00%, respectively. The two-year ADF average content was 31.07% for the same trend as the NDF capacity in the No.44, below 31.71% and 32.65%, respectively. To sum up the results, Although there was a high level of incentive sowing plot(No.39) in nutritive value, considering the botanical composition and productivity of the pasture, it is also deemed desirable to have a tall fescue plot(No.64).

Olive flounder (Paralichthys olivaceus) including red seabream (Pagrus major) and jacopever (Sebastes schlegeli) were known to be suitable characteristics for preparing a processed food because of white meat fish containing low fat in muscle. In this study, the physicochemical properties of olive flounder (46-50 cm of length, 950-1,050 g of weight), red seabream (30-33 cm of length, 1,250-1,350 g of weight) and jacopever (20-23 cm of length, 550-650 g of weight) were studied to obtain a basic data for the development of a new processed food. Head, scale, bone and viscera of each samples were removed, and then grinding with homogenizer before experiment. Moisture content of red seabream is lower than that of olive flounder and jacopever, therefore, crude protein and crude lipid are higher content. Red seabream showed higher redness, yellowess and color difference value than those of olive flounder and jacopever except lightness. The major total amino acid in olive flounder, seabream and jacopever were glutamic acid, lysine and aspartic acid in order. Especially, the highest content of free amino acid was lysine for olive flounder and jacopever and alanine for red seabream. The highest content of mineral in olive flounder, seabream and jacopever was potassium (K) and then phosphorous (P) and sodium (Na) in order. The highest amount of fatty acid in olive flounder, red seabream and jacopever was polyenoic acid in which especially contained 6.8, 7.1 and 6.7% for EPA, and 15.2, 15.2 and 17.1% for DHA, respectively. From the result of sensory evaluation, there was no significant difference in color and odor, but not in taste and texture.

This study is performed to evaluate the effects of purple Kohlrabi addition on the quality properties and stability characteristics of hamburger patties during storage. The patties were prepared by adding 0% (N), 3.3% (K1), 6.6% (K2), and 10% (K3) of chopped purple Kohlrabi. Each patty was tested in triplicate and assigned to one of the four storage periods: 0, 5, 10, or 15 days. Addition of Kohlrabi decreased the protein and lipid contents, however, the ash and moisture contents were significantly increased. The total amino acid contents of N, K1, K2, and K3 were $15.34{\pm}1.02$, $14.57{\pm}1.28$, $15.10{\pm}1.17$, and $16.70{\pm}1.23$ mg/100 g, respectively. Palmitic acid was the most abundant among the saturated fatty acids, while oleic acid was the most abundant unsaturated fatty acids among the four groups. The water holding capacity value and cooking loss were not significantly different among the patties. In the textural characteristics, the addition of Kohlrabi increased the cohesiveness and chewiness values, but did not affect the hardness and springiness values of the patties. In the sensory evaluation, an addition of 10% Kohlrabi had the best score in color, flavor, and total acceptability. The pH of the patties decreased longer period storage; however, the total microbial counts, thiobarbituric acid (TBA) value and volatile basic nitrogen (VBN) content increased during storage. The TBA value and VBN content of the patties containing 10% Kohlrabi were lower than those of the N. Kohlrabi addition decreased the b (yellowness) and a (redness) values, and did not affect the L (lightness) value. Thus, this result suggests that adding Kohlrabi of 10% can be applied to patties for its functionality.

This study was carried out to determine the effects of the fertilization levels and oversowing treatment on liveweight gain of glazing cattle, changs of botanical composition, and dry matter(DM) yield in tall fescue dominant mixed pasture during the grazing period. The treatments were T$_1$(low fertilizing; 120-100-100 kg/ha), T$_2$(medium fertilizing; 280-200-200 kg/ha) and T$_3$(medium fertilizing+oversowing). The botanical composition of tail festuce was increased in T$_1$ and that of tall fescue, orchardgrass and pernnial ryegrass in T$_3$ was 30.5%, 23.8% and 24.1%, respectively. The total forage DM yield was the highest in T$_3$, and the average stocking rate (animal unit; AU) per day during the grazing period in T$_1$, T$_2$ and T$_3$ was 2.4 AU. 3.0 Au and 3.3 AU, respectively. The total grazing days (animal unit day; AUD) in T$_3$(664 AUD) was higher than that of T$_1$, and T$_2$. There is no significant difference in average daily liveweight gain per head among the treatments but daily liveweight gain per ha in T$_3$ was higher than that of T$_1$, and T$_2$. The total liveweight gain per ha during the grazing period in T$_1$, T$_2$ and T$_3$ was 601kg. 762kg and 877kg, respectively. The herbage consumption per day per 100kg LW was similer among the treatments but crude protein, P, K and Ca contents in herbage were increased with medium fertilization levels(T$_2$) and with oversowing(T$_3$).
The effects of seeding and clipping termination dates, and seeding and fertilizer rates on forage and grain yields were evaluated in 1989 harvest year for dual production of forage and grain of naked and malting barleys in Cheju province. In the experiment I, 'Saessalbori' (naked barleY)1 and 'Doosan 22' (malting barley) were seeded on Sept. 21, Oct. 12 and Nov. 2, respectively. An unclipped(grain-only) treatment that was planted on Nov. 2 was included for check. In the experiment II, the two above cultivars were planted at seed rate of 14, 20 and 26 and kg/l0a. Fertilizer rates were 9-6-12, 17-13-8 and 22-16-11 (N-P$_2$O$\sub$5/-K$_2$O) kg/l0a. Seeding dates were Oct. 13 and Nov. 7 for clipped treatments and grain -only treatment(seeding rate: 14kg/l0a, N-P$_2$O$\sub$5/-K$_2$O=9-6-12 kg/l0a), respectively. All treatments in both experiments were harvested for grain yield. In Saessalbori, survival following forage removal was 100% regardless of seeding and clipping termination dates, and seeding and fertilizer rates. In Doosan 22, survival percenage decreased with increasing seeding and fertilizer rates when plants was clipped in January to Febuary. Forage yield of two cultivars increased with early planting and delays in clipping termination and tended to increase as seeding and fertilizer rates were increased. Crude ash and fat were not affected by seeding and fertilizer rates, and clipping date. Crude protein increased with an increase in fertilizer rate and decreased with delays in clipping date. N free extract tended to increase with delaying clipping date and decreased with increasing fertilizer rate. Earlier planting resulted in earlier heading and maturity. Clipping slightly delayed heading of Saessalbori and greatly delayed that of Doosan 22. Maturity of Doosan 22 was delayed 3 to 5 days by increased fertilization. Clipping shortened culm length more severely in Doosan 22 than in Saessalbori. The later the clipping termination, the shorter the culm length. The number of spikes per m$^2$ and the number of kernels per spike were not affected by clipping in Saessalbori while those of Doosan 22 were decreased with delays in clipping termination. Delaying forage harvest resulted In a reduction in grain yield. However, final clipping on Feb. 27 reduced grain yield of Saessalbori by only 6-11 % compared to the grain-only treatment. In Doosan 22, forage harvest after Dec. 28 resulted in 6 to 66% reduction of grain yield. The data indicate that grazing of naked and malting barleys until late Feb. and late Dec., respectively, might not reduce grain yields when planted on mid-Sept. to mid-Oct.

This study was conducted to investigate the growth performance and meat quality improvement according to castration, optimal feeding management and ruminally protected amino acid-enriched fatty acid (RPAAFA) for the unselected Hanwoo bulls in the performance test. Bulls were castrated at approximately 14 months of age. Sixteen Hanwoo steers, 15 months of age and weighing $412.9{\pm}24.9kg$, were distributed into 2 groups. Steers were fed a basal diet supplemented with RPAAFA at 0 g (control) or 100 g (treatment), respectively for 12 months. Steers were slaughtered at 27 months of age. Average daily gain for treatment tended to be higher (p=0.10) than that of control, whereas feed conversion ratio tended to be lower (p=0.07) in treatment than in control. The supplementation of RPAAFA did not affect rib eye area, back fat thickness, meat color, fat color, texture and maturity. The appearance rates of yield 'A' grade and high quality grade ($1^{++}$, $1^+$ and 1) were higher in treatment than in control. The content of moisture, fat, protein and ash in longissimus muscles were similar between control and treatment. The supplementation of RPAAFA did not affect water-holding capacity, oxidation and reduction potential, myoglobin and fatty acid contents in longissimus muscles. Thus, present results indicate that castration, optimal feeding management and RPAAFA may be recommended for improving growth performance and quality grade of the unselected Hanwoo bulls in the performance test.
This study was conducted to evaluate physicochemical and textural properties, and antimicrobial effects of low-fat comminuted sausages manufactured with sodium lactate $(3.3\%,\;SL)$ and various levels $(0.1\~0.3\%)$ of grapefruit seed extract (GSE, DF-100) during refrigerated storage for 10 weeks. Low-fat comminuted sausages (LFCS) has pH ranges of $6.09\~6.26,\;74\~76\%$ moisture, $<3\%\;fat,\;16\~17\%$ protein. The addition of SL $(3.3\%)$ and GSE with various levels $(0.1\~0.3\%)$ didn't impair water holding capacity (WHC), vacuum purge (VP) and Hunter color values (L, a, b). LFCS containing SL $(3.3\%)$ increased hardness and chewiness, whereas most TPA values were not affected by the addition of various levels $(0.1\~0.3\%)$ of GSE. LFCS containing $0.2\%\;or\;0.3\%$ GSE retarded the microbial growth of Listeria monocytogenes(LM). The addition of $0.3\%$ GSE in LFCS showed similar antimicrobial effect to $3.3\%$ SL, which kept $10^3 CFU/g$ until 10 weeks of refrigerated storage. Yellowness, VP and cohesiveness tended to be increased with increased storage time. These results indicated that the addition of $0.3\%$ GSE as a replacer for synthetic particularly paI1icuiarly inhibited the microbial growth of LM, resulting in antimicrobial effect similar to those of $3.3\%$ SL treatment without quality defects.
Background: Follow-up studies have shown that although outcomes have improved substantially over time, results of the Fontan operation and its modifications remain suboptimal. In this study, we reviewed our experience with the extracardiac conduit Fontan operation, with a focus early and midterm change of internal diameter of PTFE conduit. Material and Method: Between April 1997 and July 2000 were reviewed. Twelve patients (M:6, F:6, mean age 42.04 $\pm$ 12.43months, mean body weight 13.80$\pm$ 1.94kg) underwent extracardiac conduit Fontan operation with expanded PTFE graft. Mean cardiopulmonary bypass time was 109.7$\pm$26.99minute and mean operation time was 455$\pm$89.51minute. Intraoperative fenestration was performed in 10 patients. The aortic cross clamping was not performed in all patients. Result: There was no early deaths and no postoperative dysrhythmia. Postoperative protein losing enteropathy and prolonged pleural effusion occurred in 1(8.3%) and 4 patients(33.3%). Conduit patency was evaluated by magnetic resonance imaging studies. A 9.84$\pm$3.84% mean reduction in conduit internal diameter and there was no statistical correlation between the change of internal diameter of conduit and the postoperative duration after partial correlation analysis(r=0.019, p=0.955). Conclusion: These results demonstrate that the extracardiac conduit Fontan operation provies good early and midterm results and may reduce the prevalence of late arrhythmia. And there is no correlation between the change of internal diameter of conduit and the postoperative duration after extracardiac conduit Fontan operation with the expanded PTFE graft conduit.
