The experimental study from the beam-column subassemblies is presented. Test parameters are flexual strength ratio, joint shear stress factor and transverse steel reinforcement ratio. The results from cyclic loading tests show very ductile characteristics. In the designing of ductile moment resisting frame, therefore, transverse reinforcing effect of column and joint should be included.

Vertical deformation and lateral flow can occur as a result of the construction of nearby embankments on a soft ground. This paper considered the behavior from a model test that situated pressure berms on the soft ground by trapezodial load., as varied the height and width of the pressure berm and height(H) of the load. But width(B) of the load is equal to all tests. The test results are as follows : 1. Maximum settlement occur at the center of the embankment and ending settlement is to the depth about 1.8B from the ground surface. 2. Maximum uplift location is about 0.3B ∼ 0.4B from the toe of the pressure berm and maximum uplift deformation occur with its height at H/2 without any influence from its width. 3. The width and height of the pressure berm for mimimum uplift deformation is 2H and H/3. 4. Maximum lateral flow occur to the depth at D/3 from the ground surface without any influence from its height and width.

The possibility of using the dried powder form of Sarcodon aspratus fruitbody (a kind of mushrooms) as a meat tenderizer was explored in this study. The freeze-dried powder had higher protease activity compared to the hot air dried powder of S. aspratus. The powder kept higher activity when preserved at -20℃ than at ambient temperature. The hardness of the meat decreased and the cooking loss increased more rapidly when the meat was treated with the mushroom powder at ambient temperature than at -41℃. In terms of sensory evaluation, 0.1% of the powder based on the meat and 3 hours of treatment at 4℃ gave the highest acceptability score. In the comparison test, the meat was more acceptable when treated with the mushroom powder than with the imported commercial tenderizer. This led to the conclusion that it is quite feasible to develop a natural meat tenderizer using the Sarcodon aspratus fruitbody.

This study is the result that analyze architectural planning side and characteristic of arrangement of factory building in Industrial Complex Area. The result is as follow. (1) The division of block and land is divided by super block, and is disadvantageous to arrange because slenderness ration of land is much at process that divide. (2) It is needed land division of suitable scale by thing by special quality of location. (3) Prudent attention is required so that do not get into very much slenderness ratioes at atomization process of land at industrial estate plan.

When embankment is constructed on soft ground, lateral displacements and consolidation settlements develops. When load work on the soft clay ground, we can earn the following result through model test that is the lateral displacement by the piles embedded distance(L) and the piles spacing rate(s/D). 1. As increasing L and s/D, the maximum heaving height(HH Max) of the ground was also increasing, and the maximum heaving distance(HL Max) became far from the end of the load. 2. As L and s/D was increasing, the maximum of the lateral displacement(SL Max) became increasing, and The location of the maximum lateral displacement(SL Max) occurred in the -0.17~-0.28B spot regardless L and s/D. 3. HH Maxof the ground is proportional to SL Max

Two farmed young ostrich chicks were applied to pathology laboratory at Chungnam National University. Grossly, one ostrich showed rotated tibiotarsus, the other showed rolled toes. Case 1 ostrich was hypertrophy of fibualis longus and tibial cranialis tendon and gastrocnemius tendon in crus, inflammation of flexor digitorum longus. In histopathological views, myocytes of fiburalis longus were showed hypertrophy and hyperplasia. It is not found any specific feature in X-ray of the case 2 ostrich. Limb deformities were detected frequently in farmed ostrich chicks in 2- to 3 weeks old. Limb deformities were an important cause of mortality in farmed ostrich chicks during the first 10weeks after hatch. Cause of limb deformities were considered a nutrition problem.

Cation基의 분포가 다른 Cationic Polyacrylamides(C-PAM)의 펄프에의 흡착성 : 흡착시간의 영향에 대하여

朴成培,趙鍾洙,尹承洛,田中浩雄 진주산업대학교 농업기술연구소 1999 農業技術硏究所報 Vol.12 No.-

The adsorption of two cationic polyacrylamides (C-PAM), with similar molecular weights (MW) 5.3·10^5 and 5.1·10^5 and charge density (CD) 1.19 and 1.25 meq/g but with different distribution of cationic groups respectively has been studied. There are two kinds of substrates ; one is cellulose fiber without fine fraction, and the other is cellulose fibers with fine fraction. At the stirring speed used, the adsorption of these C-PAMs onto cellulose fibers was rapid regadless of cationic distribution, and the adsorption amount of C-PAM with homogeneous cationic distribution was a little greater than that with heterogeneous cationic distribution. This small difference is probably due to the existence of irregularities on the surface of cellulose fibers and the greater diffusion of the C-PAM with homogeneous cationic distribution. That only a small difference is observed is due primarily to the strong attraction between opposite charges. The adsorbed amounts of C-PAM gradually increased both for cellulose fibers, most rapidly for Cellulose fibers with fine fraction and most slowly for Cellulose fibers without fine fraction. These results can be attributed to the porous nature of the cellulose fibers and the adsorption area of the fine fraction.

밭토양에 처리된 규산질 비료의 유효화와 토양반응 교정효과

조현종,최희열,이용우,이윤정,정종배 한국환경농학회 2004 한국환경농학회지 Vol.23 No.2

이화학적 특성이 다른 4가지의 밭토양에 대한 규산질 비료를 처리하여 토양의 유효규산 함량과 pH 변화에 미치는 효과를 조사하였다. 토양의 이화학적 특성과 기존 유효규산 함량에 상관없이 토양 유효규산 함량은 규산질 비료 시용량에 비례하여 증가 하였다. 규산질 비료의 유효화 정도는 토양마다 차이가 있었으며 최저 9.1%에서 최고 19.2% 정도의 비율을 나타냈다. 규산질 비료 100 kg/10a 수준의 처리는 용탈 등으로 제거되지 않는 한 10 cm 깊이 표토에 평균적으로 100 mg/kg 정도 의 유효규산을 공급할 수 있는 것으로 나타났다. 퇴비 혼합처리는 토양 유효규산 함량 증가에 큰 영향을 미치지 못했으며, 석회 처리는 유효규산 함량을 다소 증가시켰다. 토양 pH 변화는 모든 토양에서 규산질 비료 시비량에 비례하여 증가하였으며, 규산질 비교 100 kg/10a 처리로 토양 pH를 0.1~0.2 단위 증가시킬 수 있는 것으로 나타났다. 따라서 산성 토양의 경우에는 규산질 비료의 시용과는 별도로 pH 교정을 위해 석회비료를 시용해야 할 것이다. Although silicon (Si) has been known to be an essential element for rice growth, the optimum soil level of Si for upland crops remains unestablished. This study was conducted to estimate the availability of Si fertilizer in upland soils, and also effect of the Si fertilizer on soil pH was examined. Different application rates of Si fertilizer were tested using four soils of different available Si levels and pHs in a series of laboratory incubation study. The treatments included Si fertilizer levels of 100, 200, and 300 kg/10a. Also to examine the effects of compost and lime on the availability of Si fertilizer in upland soil, treatment of silicate fertilizer 200 kg/10a + compost 1,000 kg/10a and lime alone treatment were included. Changes of Si availability in the soils during the incubation period were measured by 1 N NaOAc extraction procedure. Availability of Si fertilizer was different among the tested soils, and about 9.1~19.2% of the applied Si fertilizer was extracted after 60 days laboratory incubation. Application rate could not influence the availability of Si fertilizer. Application of compost with Si fertilizer could not increase Si availability in upland soils, but lime treatment could increase Si availability. Soil pH increased by application of Si fertilizer, but the effect of Si fertilizer on soil pH was minimal. When Si fertilizer is applied on the purpose of Si nutrition in acid upland soils, lime treatment should be coupled with the Si fertilizer for remediation of soil acidity.
