This experiment was carried out to determine the growth characteristic, dry matter production, crude protein yield and palatability in intercropping and pure culture. The treatments were pure vulture$lt;Sorghum × Sudangrass hybrid(Tl), Soybean (T2)$gt; and intercropping culture [Sorghum × Sudangrass hybrid$lt;T3(1)$gt; + Soybean$lt;T3(2)$gt; = T3]. The experiment was performed at the College of Natural Science of Kon-Kuk University in Chungu from 1989 to 1991. The results obtained from these experiments are as follows ; 1. In plant length, leaf length and leaf width of the sorghum × sudangrass hybrid(S.S.H)' T3(1) was higher than T1 during the experimental period(1989-1991). Also, growth characteristics of soybeans had the same tendency. 2. In the soybean and S.S.H, the number of leaves of T3(1,2) was higher compared with T1 and T2, but in the stem hardness, T2 was harder than T3(2) and T3(1) was harder than T1 in S.S.H. 3. In T3, the leaf ratio of S.S.H decreased but that of soybeans increased. However resistance to lodging of S.S.H increased and soybeans decreased. 4. In T3, S.S.H showed an increase in the number of tillers, while rate of dead stubble decreased. 5. In the first cutting time, palatabilities were 100, 71, 21% on T2, T3 and T1, respectively. but at the 2nd and 3rd cutting time, there was no difference between TI and T3. 6. Dry matter production of T1 was the highest, but the extent of yield depression was highly increased according to the times of the year. While, in T3, it was slightly increased and the yield of three years was similar to pure T1(T1 : T3 = 15,202 : 14,977㎏/㏊). 7. In protein yield, T3 was higher than pure culture(T1, T2). 8. In the change in chemical characteristics of soil, T3 was higher than T1 in the pH, organic matter, avail. P₂O_5 and total nitrogen. T3 was better than T1 for soil improvement and maintenance

S nutrition alleviates salt stress by maintaining the assemblage of photosynthetic organelles in Kentucky bluegrass (Poa pratensis L.)

Park, S. H.,Lee, B. R.,Lee, J. H.,Kim, T. H. Springer Science + Business Media 2016 Plant growth regulation Vol.79 No.3

<P>To assess the roles of sulfur (S) nutrition in salt stress tolerance in Kentucky bluegrass (Poa pratensis L.). The plants grown in S-supplied or S-deprived condition for 4 weeks were exposed to salt stress with 100 mM NaCl or non-salt stress, respectively, for 21 days. Osmotic potential was significantly decreased by salt stress from day 14. Photosynthetic pigments such as chlorophyll and carotenoid were decreased by salt stress which was more severe in the absence of S, but their content was largely recovered in the presence of S-nutrition. The proteomic analysis of multi-protein complexes in the thylakoid by BN-PAGE showed that the expression of PSI, PSII and RuBisCo level was repressed under salt stress in the absence of S, whereas their expression was largely recovered by S supply. Enzymatic activity confirmed the responses of RuBisCo, estimated by the BN-PAGE, showing a decreased activity in S-deprived and/or salt stressed levels. The decreased RuBisCo activity was significantly related to S content as affected by S nutrition and/or salt stress. Significant relationship between S content and Na, K, Fe content was also observed. These results indicate that S-nutrition modulates the negative responses to salt stress tolerance in photosynthetic organelles of P. pratensis.</P>

To evaluate the diagnostic accuracy of the measurement of free thyroxine(FT4) by radioimmunoassay, we measured free T4 and T4, T3, T3RU, TSH and TBG serum levels by radioimmunoassay in 18 healthy persons and 52 patients with various thyroid diseases and 11 normal pregnant women. The results are as follows. 1) In 19 cases of overt hyperthyroidism, T3, free T4 and FTI, T4/TBG ratio reflect hyperfunction in all cases. T4 is increased in 94%(18/19) and TBG and TSH are decreased in 79%(15/19). 2) In 8 patients with overt hypothyroidism, TSH is increased in all cases and free T4 and FTI is decreased in all cases. T4 is decreased in 87.5%(7/8), T3 is decreased in 75%(6/8) and T4/TBG ratio is decreased in 62.5%(5/8). 3) In 5 patients who are clinically in euthyroid state after treatment of hyperthyroidism, T4 free T4, FTI and TSH are in the normal range in all cases and T3 is normal in 60%(3/5) and slightly increased in 40%(2/5). 4) In 10 patients who showed clinically borderline hypothyroidism after treatment of hyperthyroidism, TSH is increased in all cases and free T4 and FTI are decreased in all cases, but T4 and T3, T4/TBG ratio are in the normal limit in all cases. So after treatment of hyperthyroidism, TSH, free T4 or FTI are recommended as optimal function test. 5) In normal pregnancy, free T4, FTI and T4/TBG ratio reflect normal function, but the other parameters unreliable due to the influence of increased TBG. Also TBG and TSH level in pregnancy is increased significantly compared with normal healthy control group. 6) The coefficients of correlation between T4 and FTI were 0.862(p〈0.001) and 0.685(p〈0.001) between free T4 and T4/TBG ratio. In most patients, diagnostic value of free T4 was comparable and even superior to FTI, so free T4 measurement can be used routinely with thyrotropin assay in the diagnosis of hypothyrodism or with T3 for the diagnosis of hyperthyroidism.

Growth characteristics and palatability by different harvesting dates were measured in order to determine its availability and effective storage period when sorghum × sudangrass hybrid were stored as foggage. Experiment was carried out with six treatments as follows; T1, T2 and T3 were foggaged at 120, 160 and 200㎝ in plant length and T4, T5 and T6 were foggaged at boot, milk and dough stage on 7 october after regrowth respectively. Rice straw was offered to examine the relative palatability a, control. 1. Growth characteristics such as plant length, leaf length, leaf width, leaf number and stem hardness were decreased with prolongation of foggage period at all treatments. Especially, decrease and falling ratio were a heigher at T5 and T6 than the other treatments. 2. Greeness grade of leaf showed fast decoloration at TI and T2 treatments, but stem showed fast decoloration at TS and T6 treatments. Leaf and stem decolorized in mid-October and mid-november in all treatments. 3. Leaf ratio was deceased with prolongation of foggage period, but stem showed gradually increase. Grain ratio was stable increase at T6 treatments, but not at T5 treatment, 4. Dry matter contents of leaf and grain were stable increased at all treatment but stem was multifarious according to weather conditions. 5. Changes of palatability were high at T1, T2 and T3 treatments untill mid-October, but T4 treatment and rice straw showed high in early December. 6. According to the results obtained in this study, it was suggested that when sorghum x sudangrass hybrid is used as foggage, foggaging period would be suitable until mid-november and growth stage for foggaging would be recommendable from T2 to boot stage for maximum availability.

본 실험은 기존 사슴사료에 있어서 육계분 발효사료의 대체 가능성을 검토하기 위해 숫사슴에 있어서 육계분 발효사료의 첨가수준을 0, 15 및 30%로 달리하여 소화율, 증체량, 건물채식량 및 질소출납에 미치는 영향을 검토하였다. 모든 처리구에서 실험사슴들은 비슷한 수준의 채식량을 나타내어 건물기준으로 체중의 약 3% 정도의 채식량을 기록하고 있어 육계분 발효사료를 30%까지 첨가한 경우 숫사슴의 채식 기호도에는 부정적인 영향이 나타나지 않는 것으로 판단되었다. 건물소화율은 Control이 76.5%로 가장 높았고, T2가 70.3%로 가장 낮아 유의성(P<0.05)이 인정되었다. 조단백질의 경우도 Control구가 75.8%로 가장 높은 소화율을 나타내었으며, T2가 70.2%로 가장 낮은 소화율을 나타내어 처리간에 유의성(P<0.05)이 인정되었다. 조섬유 소화율은 Contol구 70.8%, T1구 62.7%, T2구 56.0%로 육계분 발효사료의 첨가수준이 높아짐에 따라 조섬유 소화율이 저하되어 Control구와의 사이에 유의성(P<0.05)이 인정되었다. 건물 및 가소화 건물섭취량 모두 육계분 발효사료의 첨가수준이 높아질수록 약간씩 저하되는 경향은 있었으나 그 차이에 대한 유의성은 인정되지 않았다. 실험사슴들의 일당 증체량은 T1구에서 가장 높았으며 Control구에서 가장 낮았으나 처리간의 차이는 유의성이 인정되지 않았다. 질소섭취량은 T1구가 40.2g으로 가장 많았으며 T2구가 38.0g으로 가장 낮았으나 처리간의 유의성은 인정되지 않았다. 분 중 질소의 양은 T2구에서 가장 높았으며 뇨 중 질소의 양은 Control구가 가장 높았다(P<0.05). 체내 질소 축적량은 T1구에서 가장 높았으나 나머지 처리구들과 비슷한 수준을 유지했다. To determine nutritive value and suitability of deep-stacked broiler litter for deer, influence of supplementary levels of broiler litter on digestibility, dry matter intake, and nitrogen balance was investigated in male spotted deer (Cervus nippon) fed a commercial mixed(complete) ration. The deep-stacked and ground broiler litter was supplemented at the level of 0%(Control). 15%(TI) and 30%(T2) on the basis of fresh matter to the mixed ration. All treatments had similar palatability at about 3% body weigh of dry matter intake. Dry matter digestibility was highest in Control and lowest in T2(P<0.05). Digestibility of crude protein was lowest(P<0.05) in T2. Dry matter and digestible dry matter intake was similar in all treatments. Daily body weight gain was not affected by treatments. Feeding 15 or 30% of broiler litter to male deer resulted in similar nitrogen intake. fecal nitrogen excretion and daily nitrogen retention(g/d), compared with feeding Control. These results suggest that up to 30% of broiler litter may be fed to male deer without deleterious effects on deer performance.

This study was conducted to investigate the physico-chemical characteristics of various bone extracts in Hanwoo cattle. The experimental materials are as follows; T1(Shank bone extract), T2(Tail extract), T3(Beef feet extract), and T4(The other bones extract). In the proximate composition, the T1 and T2 showed higher moisture and fat contents than those of T3 and T4(p<0.05), and the T3 had the highest protein content among the bone extracts(p<0.05). The quality properties including salinity, sugar content, turbidity and yellowness(b*) values were significantly higher in the T3 than the other bone extracts(p<0.05). However, the pH value of T3 was significantly lower than the other bone extracts. In the mineral contents, calcium contents of bone extracts were 36.33-48.57mg/kg, and the content of phosphorus was the lowest in T1(4.62mg/kg) and T2(19.88mg/kg) was the highest(p<0.05). Contents of sodium and potassium were the highest in T3(215.83mg/kg) and T2(54.59mg/kg), while the content of magnesium was the lowest in T3(12.28mg/kg). In conclusion, these results could be suggested to be the basis information for processed meat extract products industry in korea using Hanwoo bone extract.

Y. J. KIM, J. G. JI, J. T. KIM, J. H. HONG, J. S. LEE, H. S. LEE, S. B. PARK. A comparison study for mask plantar pressure measures to the difference of shoes in 20 female. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 83-98, 2004. The purpose of this study was to investigate the test-retest of plantar pressures using the F-Scan system over speeds and plantar regions. 6 healthy female subjects in 20's were recruited for the study. Plantar pressure measurements during locomotor activities can provide information concerning foot function, particularly if the timing and magnitude of the loading profile can be related to the location of specific foot structures such as the metatarsal heads. The Tekscan F-Scan system consists of a flexible, 0.18mm thick sole-shape having 1260 pressure sensors, the sensor insole was trimmed to fit the subjects' right. left shoes - sneakers shoes & dress shoes. It was calibrated by the known weight of the test subject standing on one foot. The Tekscan measurements show the insole pressure distribution as a function of the time. This finding has important implications for the development of plantar pressure test protocols where the function of the forefoot is important. According to the result of analysis it is as follows : 1) Center of force trajectory in women's dress shoes display direct movement, compare with center of force trajectory in Sneaker shoes displays a little bit curved slow pronation movement. Sneaker shoes in forefoot part display very quick supination movement, therefore, this shoes effects negative effectiveness for ankle's stability. Considering center of force trajectory analyzing, the more center of force close straight line, the more movement can be quick movement for locomotion. For foot pressure distribution, center of force trajectory in locomotion is better to curved trajectory with pronation movement. So sneaker shoes style is good shoes considering center of pressure distribution trajectory compare with women's dress shoes. 2) Women's dress shoes increased peak pressure in medial, this is effected by high hill's height. The more increased women's dress shoes's height, the more women's peak pressure will increase, pronation can increase compare with before. Supination movement increase, this focused pressure in lateral, also, supination increased more. If the supination movement increased, foot pressure focused in lateral, therefore, it is appeared force distribution in gait direction. This is bad movement in foot's stability. 3) Women's dress shoes in landing phase displayed a long time, this is when women's dress shoes wear, gait movement is unbalance, so, landing phase displayed a long time. For compensation in gait, swing phase quick movement. 4) Women's dress shoes displayed peak pressure distribution in lateral of rearfoot part, Sneakers shoes displayed peak pressure distribution in medial of forefoot part. Its results has good impact absorption compare with women's dress shoes. In forefoot part, sneakers shoes has good propulsive force compare with women's dress shoes.
