This study was conducted to evaluate the effects of different nitrogen levels on the yield and nutrient quality of a newly developed domestic hybrid of Teosinte, Geukdong 6〔Zea mays L. subsp. mexicana (Schrad.) H. H. Iltis〕. The field experiment was conducted in a randomized block design with three replicates and consisted of four nitrogen (N) application rates, T1 (200 kg/ha), T2 (300 kg/ha), T3 (400 kg/ha), and T4 (500 kg/ha). No differences were found in plant length, leaf length, leaf width, leaf number, dead leaves, stem hardness, tiller number, and fresh yield (p>0.05). The T3 showed significantly greater dry matter yield at harvest (heading stage) compared to the other treatments (p<0.05). The crude protein content of T4 (10.49%) was higher than those of T1 and T2 (p<0.05). However, there was no significant difference between T4 (10.49%) and T3 (9.63%). The effects on crude fat, crude ash, neutral detergent fiber (NDF), acid detergent fiber (ADF), and crude fiber were not significant (p>0.05). The sugar content was higher in the T2 treatment than the other treatments (p<0.05). For Ca, T3 showed significantly greater content (p<0.05). However, no significant effects were found in the contents of Cu, Fe, K, Mg, Mn, Mo, and Zn (p>0.05). Na content was higher in order of T2 > T4 > T3 > T1 (p<0.05). Total mineral contents were not significantly different among the treatments (p>0.05). Given these results, we recommend the amount of nitrogen fertilization necessary for "Geukdong 6" to be around 400 kg per ha (T3), when considering, high fresh yield, dry matter yield, number of leaves and content of crude protein.

The present study compared leptin, adiponectin, and thyroid hormone concentrations in normal and obese dogs, and evaluated the association between leptin and adiponectin concentrations and thyroid function. The serum leptin, adiponectin, thyroid-stimulating hormone (TSH), total thyroxine (tT4), free thyroxine (fT4), triiodothyronine (T3), and cortisol concentrations were measured in 18 normal dogs (body condition score [BCS]: 4-5/9) and 16 obese dogs (BCS: 8-9/9). Leptin and T3 concentrations were higher in the obese group than the normal weight group (p < 0.01 and p < 0.05, respectively). In both groups, the T3 and leptin concentrations were correlated (r = 0.370, p < 0.05), as were the TSH and fT4 and adiponectin concentrations (r = -0.373, p < 0.05 and r = 0.369, p < 0.05, respectively). In the normal weight group, the TSH and fT4 concentrations were correlated with the adiponectin concentrations (r = -0.528, p < 0.05 and r = 0.482, p < 0.05, respectively). The results of the present study suggest that leptin and T3 concentrations are significantly higher in obese dogs than normal weight dogs, and the serum T3 and leptin concentrations are positively correlated.

Effect of period of adaptation and levels of monensin were studied for microbial fermentation/ digestibility to find out the optimum period of adaptation of monensin in rumen and suitable level of monensin in wheat straw+concentrate and wheat straw+UMMB diet. The mean digestibility of dry matter was decreased upto T-3 treatment (49.17%), however, digestibility of DM was affected upto period (P-2). NDF digestibility was affected due to treatment under P1 and P2 (p<0.05). Average digestibility of ADF was increased to 53.33% at T-3 level of monensin and P4 days of adaptation. TVFA (mmole/100 ml) were decreased from 9.49 in T-1 to 7.70 in T-7. Periods were not effectives except P2 (14 days of adaptation). Similarly, total gas was decrease with the increase of monensin levels in diet. Although acetate percentage in TVFA was not affected either due to level of monensin or period of adaptation but propionate was increased due to increase in monensin at 21 days of adaptation (P-3). Butyrate (%) was decreased significantly in T-2 to T-6 as compared to T-1 group. Total gas was significantly (p<0.01) higher in group T-1 (control) and it reduced significantly in T-5, however, differences in gas production between group T-3, T-5 and T-7 at P-1 was not significant. Methane production was reduced on P-3 and P-4 level of adaptation due to treatment. The overall result indicated that 21 days of adaptation with monensin was sufficient to mask the inhibiting effect of monensin to cell wall digestibility and 35 ppm monensin is optimum to reduce methane production and increase propionate productions.

This study was conducted to utilize as the fundamental data for the improvement in curriculum, practicum programs and educational facilities of four-year universities with dental hygiene department which have increased rapidly by through analyzing the satisfaction level of dental hygiene students in four-year and three-year colleges with their departments. The findings of the study were as follows: 1. The satisfaction level with their department of dental hygiene students who were surveyed was 3.18 out of possible five points, which was on the average. 2. As for satisfaction level with the departments by educational system, the students who were in four-year colleges in the metropolitan area expressed lower satisfaction than the students who were in local and three-year colleges. The three-year college students were more gratified with the curriculums than the four-year college students(t=2.03, p<0.05), and the latter was more satisfied with the educational facilities(t=-4.12, p<0.001) and interpersonal relationships(t=-3.07, p<0.01) than the former. 3. In the case of the three-year college students, those whose colleges were located in the metropolitan area were more contented with the educational facilities(t=5.28, p<0.001), and there were no significant differences in satisfaction level with other factors. 4. In the case of the four-year college students, the local college students were more contented with the curriculums(t=-5.39, p<0.001), educational facilities(t=-5.18, p<0.001) and the departments(t=-3.98, p<0.001) than their counterparts in the colleges located in the metropolitan area. In terms of satisfaction level with the department of dental hygiene, the four-year college students located in the metropolitan area expressed noticeably lower satisfaction with the curriculums than the local and three-year college students. As a result, the development of each curriculum which is suitable for the four-year course is required, and so is the improvement in the educational facilities as well.

This study was carried out to investigate the influence of the seeding dates on the yield and feed value in cultivating Italian rye grass on paddy soil. The field experiment was designed in a randomized block design of 3 repetitions with seeding dates of Oct. 19 (T1), Oct. 26 (T2), Nov. 2 (T3), Nov. 9 (T4), and Nov. 16 (T5) treatments. Plant length, fresh yield, dry matter yield and TDN yield were increased with early seeding dates (p<0.05). Crude protein, Crude fat and crude ash were increased with early seeding dates (p<0.05). On the other hand, NDF, ADF and Crude fiber were decreased with early seeding dates (p<0.05). Total mineral contents were higher in the order of T4 > T3 > T5 > T1 > T2 (p<0.05). The total composition amino acid content was decreased significantly (p<0.05) as the seeding dates delayed. Total free sugar content was highest in T1, whereas the lowest in T5 treatment (p<0.05). Nutrition yields (crude protein, crude fat, amino acid and free sugar) were increased significantly with early seeding dates (p<0.05). The above result indicated that it is favorable to seed soon after rice harvest to increase dry matter yield and nutrition yield of Italian ryegrass in the midlands.

Sixteen somimembranosus muscles were seamed out from sixteen left carcasses. They were cut into $7{\times}10{\times}2cm$ pieces and mixed randomly. Samples were assigned to four treatments: (T1) soy-based sauce; (T2) Kimchi-based sauce; (T3) pickled shrimp-based sauce; and (T4) onion-based sauce. Each treatment was aged in plastic box at $1^{\circ}C$ for 10 days. These samples were vacuum-packaged after treatment with sauces and held in a chill at $1^{\circ}C$ for 28 days. The pH of aged port in general, was decreased significantly (p<0.05) with storage in all treatments. Its falling rate was the slowest in T4 of all treatments, while it was faster in T2 and T3 than in T4. The salinity of aged pork was decreased (p<0.05) for T2 with increased storage days, but increased (p<0.05) for T1. The salinity showed T2 to be significantly higher (p<0.05) than T1 and T4 on 1 day, but to be lower(p<0.05) than T1 on 28 day. The saccharinity of T3 was significantly higher (p<0.05) on 1 day than those of T1 and T4, but decreased (p<0.05) on 14 and 28 day. While saccharinity of T1 was significantly the lowest(p<0.05) of all treatments on 1 day and increased (p<0.05) with increased storage days. For T1 and T2, the WHC (water holding capacity) results showed higher (p<0.05) on 14 day than on 1 and 28 day. On 28 day, the WHC result showed T4 to be the highest(p<0.05) of all treatments, but T2 to be the lowest (p<0.05). On 28 day, the shear force results showed a big difference (p<0.05) among treatments, being in order of T4>T3>T2>T1. Panelists rated T1 as having higher(p<0.05) aroma, flavor and overall acceptability than other treatments.
