The steelmaking dust treatment process has been established through reducing volatilization method in rotary kiln. The more content of zinc in reduced pellets and basicity of pellet is in the range of 1.5~3.0, the more working time needed in rotary kiln, because of decreasing wall accretion. A portion of well forming kiln coating in the furnace is a fourth of the total length from the outlet. Constitutes on the furnace wall accretion composed of the mixtures such as Fe, FeO, Fe₂O₃, Fe₃O₄, ZnO and CaO-SiO₂system, and formation of kiln coating is decreased by adding coke ratio.

This study was to look for cutting conditions which are safe, comfortable and contributable to the increase in productivity at the time in turning. The shape of chips while turning have a strong effect on cutting processing. If chips fail to be well controlled, systematic cutting is not possible by revolution of chips entangled with workpiece or damage of tool edges, and this causes problems threatening the safety of the operator. This study is designed to identify conditions which chips effectively controlled and able to treat properly, and the results are as follows: 1. Feed rate, which determined the shape of chips, was found to have a stronger impact on the shape of resulting chips than any other cutting condition. 2. When feed rate was 0.25mm or over, controlled chips(coil spring type) were produced under whatever cutting conditions. 3. When feed rate was 0.25mm or over and depth of cut was 1.0mm, well-controlled shorter coil type chips were produced at every spindle speed, which implied they were the most suitable cutting conditions. 4. Feed rate 0.2mm was found to be an unstable section where coil spring and linear mixed type chips were produced together, and as feed rate decreased, more linear chips beyond control were produced. 5. At the same spindle speed, as the diameter of the material became bigger, controlled chips were produced only when the depth of cut was reduced, and vice versa under feed rate 0.2mm. 6. At the same feed rate, the lower spindle speed was, the more stable chips were produced.

This study to convert strontium sulfate into strontium carbonate after reduction to strontium sulfide soluble in water was performed with sodium carbonate solution at various temperature. The results obtained from the above are as follows. The reduction temperature of strontium sulfate to strontium sulfide was 800℃. But strontium sulfide was reoxidized to strontium sulfate at the over 1000℃. Lid of reaction vessel closed up influenced increasing carbon activity during the reduction of strontium sulfate to strontium. Leachability of strontium sulfide reduction from strontium sulface in water was increased at high temperature, but decreased at 6mole carbon ratio because of excess carbon not reacted. Recovery of strontium carbonate from strontium sulfate was high at he high concentration of sodium carbonate solution, but low at 3 and 6 mole carbon ratio relatively Recovery of strontium carbonate from strontium sulfide was increased at high temperature, but decreased at 3 and 6 mole carbon ratio relatively. Agitation effect so accelerated to increase recovery of strontium carbonate. Impurities exist in cellestite as calcium sulfate, calcium carbonate, barium sulfate and barium carbonate compounds were not converted into other compounds during reduction of strontium sulfide from strontium sulfate. These compounds insoluble in water are able to be removed during water leaching of strontium sulfide.

Effects of martensite morphology and tempering on quasi-static and dynamic deformation behavior of dual phase steels were investigated in this study. Dynamic torsional tests were conducted on six steel specimens, which had different martensite morphology and tempering effect, using a torsional Kolsky bar, and then the test data were compared via microstructures, tensile properties, and fracture mode. In the intermediate annealed (IA) specimens, small martensites were well distributed in the ferrite matrix, but bulky martensites were mixed with ferrites in the step quenched (SQ) specimens. Under a dynamic loading condition, the fracture mode of SQ-specimens was changed from cleavage to ductile fracture as the tempering temperature increased, whereas IA-specimens had a ductile fracture mode, irrespective of tempering. These phenomena were analyzed using a rule of mixtures, phase continuity, and interfacial strength between martensite and ferrite.

Allele-and genotype frequencies of the two short tandem repeat (STR) loci, HumFGA and D21S11, were determined in Korean population(n=196). DNA typing was accomplished by applying fluorescence-labeled PCR products and a differently labeled sequenced allelic ladders, followed by automated analysis using ABI 377 automatic sequencer and GeneScan 2.02 software. Prior to typing, allelic ladder of each locus was constructed with a combination of all alleles occuring from the population sample. A total of 15 alleles and 48 genotypes with the heterozygosity of 0.854 for HumFGA, and 12 alleles and 33 genotypes with the heterozygosity of 0.787 for D21S11 are observed in a population of 196 genetically unrelated individuals. No deviations from Hardy-Weinberg equilibrium were observed(p=0.753 for HumFGA, p=0.262 for D21S11). The data presented here (power of discrimination and average power of exclusion) show that both STR Loci, HumFGA and D21S11, are very informative for individualization from criminal evidences, and are also useful for parentage testing.

A survey in Kyungnam and chungbuk areas revealed that the average number of years for persimmon tree farming is 10 and 5 years, respectively. The number of trees per orchard is at least over 20, and the farmers have been usually advised through an agricultural center, an agrochemical store, or agrochemical research center. The varieties of the persimmons they grow are Buyu and Seocheon in Kyungnam, and Doogsi and Wolha in Chungbuk. The kind of fertilizers they sprayed in early spring is either compost or composite fertilizer. persimmon pests are often found in persimmon fruits while on a tree or in storage. Phamathion, Padan, Konido, Sinpamathion, and/or supuraside is usually used to control persimmon fruit moths, aphides, leafrollers, and scale insects. To understand the developmental ecology of the persimmon fruit moth, Stathmopoda masinissa Meyrick, we collected and reared them under the laboratory condition which is at 25±1℃ of temperature, 16L:8D of photoperiod, and 85% of relative humidity.
