The subject is reviewed with respect to the regulatory of feed intake in the ruminants. The importance of physical and physiological or metabolic regulatory mechanisms are discussed in relation to their effects upon the formation of various metabolites known to be rebated to feeding. Also, reviewed the role of rumination as a physical regulatory mechanisms.

A feeding trial and digestibility tests were conducted to know the effects on fattening performance and digestibility of steam-rolled corn and barley grain compared with ground ones. Twenty eight Korean Native bulls (350㎏) and 16 mature rams were used as test animals for 100 days in feeding trial and 15 days in digestibility test, respectively. The steam-rolled corn grain were significantly(P$lt;.05) increased in DM and NFE digestibility, and in TDN content compared ground one. The steam-rolled barley, however, did not response (P$lt;.05) in statistics of those, but tended to be increased. In feeding trial, the animals fed steam-rolled corn grain were increased body weight gain and decreased feed consumption per ㎏ gain compared the animals fed ground one. Otherwise, the animals fed steam-rolled barley were de creased body weight gain and increased feed consumption per unit of gain com pared ground one. In slaughtering result, the carcass percent did not differ between steamrolled and ground in both of the grains.

Transplanted Miscanthus sinessis was studied for the evaluation of nutritive value in relation to the stage of maturity. Plants were cut at eight stages of maturity beginning on June 9, and at ten-day intervals until August 23. The dry matter content of the plant was approximately constant until July 19, which was the early boot stage, and increased rapidly until August 23. The protein content decreased uniformly with each delay in cutting until July 29 which was the prebloom stage, and leveled off until August 23. The protein content until the prebloom stage was similar to that of timothy hay. The CWC and ADF contents increased fast in earlier stages of maturity and leveled off in later stages. While lignification accelerated in later stages of maturity. Until the early bloom stage, the CWC content of Miscanthus sinensis was not high compared to other grass hays. But after the midbloom stages, it was the same or a little higher `than coastal Bermuda grass pellets. A linear relationship (Y=-0.473x+94.3, R²= 0.986) between the in vitro DDM (Y) and cutting date (x) was found. The DDM declined at a rate of 0.47% per day for each day`s delay in harvesting after June There was no relationship between calcium and phosphorous content and cutting date. The average calcium content was lower than in the early bloom stage of timothy hay, and phosphorous content was similar to that of timothy hay.

배동호,최용식 成均館大學校 科學技術硏究所 1983 論文集 Vol.34 No.1

Stress corrosion cracking may be defined as the spontaneous failure of a metal resulting from the combined effect of corrosion and stress. Particularly, under the specific corrosive environments contained chloride and sulphide, high strength steels and alloys are very susceptible to stress corrosion cracking. Accordingly, in this investigation, the stress corrosion cracking characteristics in the aluminum alloy AA6061-T6 sheet for the various percents NaCl solution environments wens studied. Experiments were conducted with the symmetric double edge cracked specimens at 80℃ and the various percentages of 5%, 10%, 15% and 20% in experimental room temperature. In order to accelerate the tests, 0.35% H_2O_2 was added to the NaCl solutions. The results obtained are as follows: (1) AA6061-T6 sheet in 5%, 10%, 15% and 20% NaCl solutions at 80℃, S.C.C. was occurred and according to rise the percents of NaCl solutions, incubation period was delayed and the crack growth rats was accelerated. In all cases, the crack propagation in the directions approximately perpendicular to the applied tensile stress. (2) S.C.C. behaviors in rte Log d(2a)/dt vs. K_1 relation curves provide a full representation ion I , region II and region III. (3) K_1S. c.c. value is defined around 39kg·mm^-3/2 for the AA6061-T6 sheet. (4) K_1c value is defined around 50kg·mm^-3/2 for the AA6061-T6 sheet. (5) The relation of d(2a)/dt vs. K_1 for region II is as follows: d(2a)/dt = C·10^mk1. The value of constant m is found 8.19 x 10 exp(-2).

Succinylation이 분리 대두단백의 기능적 특성에 미치는 영향

이시경,배동호 建國大學校附設 農業資源開發硏究所 1998 農資源開發論集 Vol.20 No.-

This study was conducted to investigate the effects of succinylation on some functional properties of soy protein. Succinylated soy protein isolate showed higher solubilities at the pHs higher than its isoelectric point and lower solubilities at the pHs lower than its isoelectric point. Generally succinylation shifted the isoelectric point of soy isolate approximately 0.5 pH unit from pH 4.5 to 4.0, however, the effects of NaCl concentrations on the solubility of succinylated soy protein were not significant. Succinylated isolate had much higher viscosity than unmodified isolate and in the pretence of NaCl, the viscosities of both protein solutions increased sharply at the low concentration of NaCl (≤0.05M) and the value decreased gradually at NaCl concentrations higher than 0.05M. Succinylation also increased the emulsifying activity and emulsion stability of soy isolate from 62.75 and 52.38% to 93.33 and 88.89%, respectively Succinylation of soy protein isolate substantially enhanced its foam capacity and foam stability from 2a.5 and 17.5% to 40.7 and 35%, respectively. The increased solubility results in the increase of protein recovery and yield. Succinylated soy protein can be utilized in the manufacture of processed foods, such as, baked goods, processed meats, meat analogues, meat extenders and numerous dairy products as emulsifiers, thickener and foaming agent due to the improved viscosity, emulsifying properties and foaming properties.

경북지역에서 생산된 사과박을 착유우 TMR의 38.7%로 이용했을 때 사료섭취량, 젖생산량, 유조성분 등에 미치는 영향을 알기 위하여 관행 사료를 대조구로 한 60일간의 사양시험을 실시하였다. 최고 비유기가 지난 Holstein 12두를 2구로 나누어 완전 임의 배치하였다. 사과박-TMR을 급여한 젖소의 진물 섭취량은 21.8㎏으로서 대조구의 16.5㎏에 비하여 32% 증가(P<.01)했으며, 젖생산량은 사과박-TMR 급여구가 22.4㎏으로서 대조구의 19.7㎏에 비하여 13.8%증가(P<.01)하였다. 유단백질 함량은 사과박-TMR구가 뚜렷이 증가(P<.01)했으나 유당의 함량은 감소(P<.01)했다. 유지방과 무지고형분(SNF)함량은 시험 구간에 차이 (P>.05)가 없었다. 사과박 TMR을 급여한 구의 체중은 대조구에 비하여 증가(P<.05)하였으며, 젖 ㎏ 생산당 사료비는 사과박-TMR을 급여한 것이 많이 소요되었으나, 생산된 총 유대에서 총 사료비를 제한 조수익은 사과박-TMR급여구가 많았다. Twelve Holstein milking cows were used to determine the effect of the total mixed ration that was formulated with fresh apple pomace(AP-TMR) as a major ingredient(39%, as fed basis) on dry matter intake, milk yield and milk chemical composition. AP-TMR was compared to conventional feeds (control). Dry matter intake and milk yield of the cows fed AP-TMR increased(P<.01) 32% and 13.8%, respectively, compared to those fed control diet. The dry matter intake and milk yield of the AP-TMR were 21.8㎏ and 22.4㎏, respectively. The cows fed AP-TMR increased (P<.01) their milk protein content, but decreased (P<.01) their lactose content in milk, compared to those of the control. The milk fat content and solids-non-fat in milk showed no significant differences(P>.05) with treatments. The body weight gain increased in the cows fed AP-TMR compared to that of the control. The feed cost per ㎏ milk production was higher with AP-TMR, but the gross income (caculated as total milk cost minus total feed cost) was higher with AP-TMR than the control.

Fatigue Design Approach for the Spot-welded T-type Member Using a Simulated Single Spot-welded Joint

배동호,박선규,이규영 한국자동차공학회 2008 International journal of automotive technology Vol.9 No.2

In order to develop a fatigue design method for actual railroad car and commercial vehicle body structures using the fatigue data of simulated single spot-welded lap joints, we first analyzed the stress distribution and evaluated fatigue strength of spot-welded T-type members that are the components of actual railroad car and commercial vehicle body structures. Next, fatigue design approach of these members using the fatigue data of single spot-welded lap joints was investigated. From our results, we found that, even though there was a quantitative difference of fatigue strength between the single spot-welded joint and the actual members over the same number of fatigue cycles, through the use of appropriate correction, the fatigue design criterion of actual spot-welded members, such as those used in railroad car and commercial vehicle body, can be predicted using the fatigue strength of single spot-welded joint.
