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 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.

본 연구는 뇌졸중 환자들의 퇴원 후 1개월까지의 물리치료양상 및 기능변화와 이에 관련된 요인을 알아보기 위해 1998년 1월 1일부터 5월 31일까지 약 5개월 간 부산시, 대구시, 구미시 및 안동시 등에 소재하고 있는 1개 병원에서 물리치료를 시작한 뇌졸중환자 87명을 대상으로 물리치료를 시작한 시점, 1개월 후, 퇴원 시, 그리고 퇴원 후 1개월이 지난 시점까지 추적하여 기능변화를 평가하였다. 뇌졸중환자의 물리치료 시작시점의 BI점수는 26.32였고, PS점수는 11.34이었다. 물리치료 시작시점을 기준으로 할 때 입원 1개월 후의 81점수 변화는 평균 16.61(p<0.001). 퇴원 시는 33.51(p<0.001), 퇴원 1개월 후는 43.56 만큼 호전되었다(p<0.001). PS점수도 각각 -2.1, -3.94, 그리고 -5,52만큼 호전되었다(p<0.001). 그리고 퇴원시에 비해 퇴원 후의 변화도 81점수는 10.06만큼, PS점수는 -1.51만큼 모두 유의하게 호전되었다 (p<0.001). 물리치료 시작시점과 회원시의 BI점수 변화와 유의한 관련이 있는 요인은 물리치료 시작시점의 BI점수와 연령이었는데(p<0.05), 시작시점의 BI점수가 낮고 연령이 낮을수록 기능호전이 컸다. 시작시점과 종료시점 사이의 변화는 시작시점의 BI점수. 퇴원시의 BI점수, 종교유무가 유의하게 관련이 이었다(p<0.05). 즉, 종교를 믿고 있거나 물리치료 시작시점의 BI점수가 낮고 퇴원시의 BI 점수가 높을수록 기능호전이 컸다. 퇴원 시와 1개월 후에는 퇴원시의 BI점수와 종교유무였는데, 퇴원시의 BI점수가 낮고 종교를 믿는 환자에서 기능호전이 유의하게 컸다.(p<0.05). 물리치료 시작시점과 퇴원시의 PS점수 변화와 유의한 관련이 있는 요인은 물리치료 시작시점의 PS점수였는데(p<0.05), 시작시점의 PS점수가 높을수록 기능호전이 컸다. 시작시점과 종료시점사이는 시작시점의 PS점수, 퇴원시의 PS점수, 퇴원 1개월 후에 적극적으로 물리치료를 받았는지의 여부 등이었다(p<0.05). 즉, 시작시점의 PS점수가 높고, 퇴원시의 PS점수는 낮으면서 적극적으로 물리치료를 받은 환자가 기능호전이 켰다. 퇴원 시와 1개월 후에는 퇴원시의 PS접수가 높고 적극적으로 물리치료를 받을수록 기능호전이 유의하게 컸다(p<0.05). 이상의 결과를 요약하면, 뇌졸중환자의 물리치료 효과를 BI점수로 평가하면 물리치료 시작시점 및 퇴원시의 BI점수, 연령 및 종교유무가 중요한 요인이고, PS점수로 평가하면 시작시점 및 퇴원시의 PS점수와 퇴원 1개월 후에 적극적으로 물리치료를 받았는지의 여부가 중요한 요인으로 생각된다.

돼지 뒷다리 부위를 동일한 비율의 양념액((T1, 간장소스; T2, 김치소스; T3, 새우젓소스; T4, 양파소스)에 침지하여 $1{\pm}1^{\circ}C$에서 30일간 저온에서 숙성기간 동안 양념 돈육의 품질 특성을 측정한 결과는 다음과 같다. 숙성기간동안 pH는 T3구가 가장 높게 나나났으며(p<0.05), 염도와 당도는 T1구가 높았다. 보수력은 T3를 제외하고는 숙성기간 동안 유의적인 차이가 없었다(p>0.05). 전단가는 T1구와 T4구는 숙성기간이 경과함에 따라 증가하였다(p<0.05). VBN은 T1구와 T3구는 숙성 20일까지 증가하다 30일에 다시 감소하였으며, T2구와 T4구는 숙성 20일 이후 급격히 증가하였다(p<0.05). TBARS는 T1구는 숙성 초기에 비해 숙성 20일 이후 크게 증가하였으며(p<0.05), T2구는 전 숙성기간 동안 큰 차이를 나타내지 않았다. 표면육색의 경우 L*값은 숙성 초기에 비해 숙성 말에는 감소하는 경향을 나타내었으며, a*값과 b*값은 숙성기간에 따라 T2구는 증가하고 T4구는 감소하였다. 심부육색에서 L*값은 숙성기간에 따라 T1구와 T3구는 낮아졌고 T4구는 유의적인 차이를 보이지 않았다. a*값과 b*값은 숙성기간에 따라 모든 처리구에서 증가하는 경향을 나타내었다. 총균수는 대부분 숙성 10일까지는 상승하다 숙성 말기에는 다소 감소하는 경향을 나타내었다. 처리구 간에 T3구는 숙성 초기부터 높게 나타났다(p<0.05). 대장균 수는 T4구를 제외한 나머지 처리구들에서는 숙성기간에 따라 감소하였다. 유산균 수는 T3구를 제외한 나머지 처리구들은 숙성기간에 따라 감소하는 경향을 나타내었다. 관능검사 결과 숙성기간에 따라 일정한 경향은 나타나지 않았으며 숙성 초기에 T4구에서 향, 풍미, 연도가 다른 처리구들보다 높게 나타났으며, 숙성 10일과 20일에는 T1구가 모든 항목에서 높은 점수를 나타내었다. 본 연구결과를 종합하면 처리구 간에 주목할 만한 품질의 차이는 나타나지 않았으며, 각 처리구마다 각각의 고유한 품질 특성을 나타냄으로써 숙성 양념육으로서의 가치를 가질 수 있을 것으로 판단된다.

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.
