  • In order to identify the optimum seeding rate of Jeju barnyard grass (Echinochloa crusgalli var. fiurnentacea(Roxb) Wight), 15, 20, 25, 30, 35 and 40 kilograms per a hectare were planted in April 16, 2000, respectively. The growth characterization, the yield and chemical composition were then investigated in June 28(1st cutting) and August 30(2nd cutting), 2000. According to increasing the seeding rate, plant height(155.5 to 162 cm), the yield of fresh forage(61 to 73 MT/ha), dry matter forage(11.9 to 16.9 MT/ha), crude protein(0.9 to 1.6 MT/ha), and TDN(6.1 to 9.7 MT/ha) were gradually increased until the seeding furrow, 35 kg/ha. In 40 kg/ha of seeding furrow, however, those results were decreased than that of the former seeding furrow. The contents of crude protein(7.4 to 10.4%), ether extract(3.3 to 5.2%), nitrogen free extract(46.4 to 47.8%), and TDN(52.1 to 60.4%) were also similar to those of the plant heights and the each yield excepted the seeding furrow, 40 kg/ha. Namely, the each results about the contents increased in 40kg/ha of seeding furrow. According to increasing the seeding rate, the stem diameter, number of leaves, number of withering leaves, and fresh weight were gradually decreased. The contents of crude fiber(30.3 to 27.5%) and crude ash(12.7 to 9.0%) were also decreased These results showed that the optimum seeding rate for the best of the feed production was the seeding furrow, 35 kg/ha.

  • Experiments were performed to investigate the condensing heat transfer characteristics of non-azeotropic mixtures of R-22 and R-114 in a heat pump system with a horizontal smooth tube as a condenser. The ranges of parameters, such as heating capacity, mass flow rate of refrigerant and quality were 780-3,480W, 24-71kg/h, and 0-1, respectively. The overall compositions of R-22 in a R-22/114 mixture were 25, 50, 75 and 100 per cent by wight. The results show that the overall condensing heat transfer coefficients for the mixtures were lower than the pure R-22 values. Local heat transfer coefficient of the pure R-22 was hghest at the top of the test tube. The local heat transfer coefficient of R-22/114 (50/50 wt%) at side and bottom of the test tube was higher than that at the top. From the obtained data, a prediction for the condensing heat transfer coefficients of the mixture was done based on the method of Fujii.

  • Recently, the broken concrete lumps resulting from the demolition of concrete structures are creshed for reuse as aggregates(i.e. recycled fine and gravel). And also, in the processing of crusing, the recycled powder of an equivalent of between 20% to 30% by wt.% of the broken concrete lumps is generated. The extensive research of recycled concrete aggregates has been carried out in various parts of the world. But less reseatch on the reuse of recycled concrete powder has been carried out. It is the purpose of this report that the study on the quality evaluation of recycled aggregates for recycled concrete. In specially, this report deals with the properties such as flow, compressive strength, bending strength, drying shrinkage and wight loss rate of mortars replaced standard fine aggregate with recycled powders at the rate of 3, 7, 15, 20 and 30 wt.%. Since the characteristics of recycled mortars with the recycled powders were comparable to those of the normal mortar without the recycled powders as described above, its concretes could be found extensive application in such field as concrete products.

  • Hydraulically filled ground is formed by the settling of soil grains from the mixture of soil grains and water. It was generally known that the settling speed of the soil grains in governed by Stokes low. In the case of clayed dredged material, the shape of soil grains is not round, the surface of the soil grains is relatively large compared to the weight of soil grains and inter-grain ionic force is relatively large compared to the wight of soil grains. By this reason the settling and consolidation behavior of hydraulically filled quite different from that of Stokes law. This study investigated the settling and consolidation behavior of hydraulically filled materials of Yeochon industrial complex by large scale laboratory settling & consolidation container. The test results showed tat actual settling speed of soil grains in quite large compared to that of Stokes law. It was turned out that this phenomenon was due to the aggregation of soil grains. Also, it was truned out that the void ration and water content after the completion of settling process was 8.7 and 322% respectively. The consolidtion settlement of clayey hydraulic fill material was predicated better by "incremental small strain" consolidation concept than classical Terzaghj's consolidation concept (infinitesimal strain).
