In this paper we have proposed a method for solving a four-coloring problem using adjusted information transmission between adjacent neurons in neural networks. These algorithms are based on McCclloch-Pitts binary neuron model neural networks. If a map shares n regions, a 4×n neural array is used to color a map of n regions where each neuron as a processing element performs it. By programming these algorithm by a C-language in IBM PC 486 DX and adapting it to various examples, we have showed the ability of our system. If one neuron is selected among four neurons, the strength of order three neurons is wakened. So, by transmitting the information of selected neuron, adjacent neurons cannot share the same color.

This study is a experiment on the mechanical properties of concrete according to the fiber additional quantity of bamboo. The experiment and analysis results are as the following. The slump as a quality of the concrete not to harden showed to decrease more remarkably for a slump value than the plain according to the increment of cellulose additional rate. Air quantity showed to increase only in 0.2% fiber additional rate and to get out of KS allowable error of bad air content in 0.4% and 0.6%, and capacity mass by unit showed a reverse tendency against air quantity according to the change of cellulose additional quantity. Compression intensity as a quality of hardening concrete showed collectively a tendency to decrease in the remnant past days except only 0.6% at the standard past day 愀8 and the initial 3 days. Pulling intensity showed to increase more than the plain in all past days according to the change of fiber additional quantity of bamboo, and bending intensity also showed to be higher revelation intensity than the plain in the measurement result at the standard past day 28. In the result of length change rate, we can find the bigger the cellulose additional rate as a special quality increased, the more it decreased according to the pass of the past day.

류현기 忠州大學校 2007 한국교통대학교 논문집 Vol.42 No.-

The research examines usability of mine-waste of talc as concrete material from a viewpoint of recycling, and derives the following conclusion. The experiment on pulverizing method for fine and coarse aggregate showed that as for fine aggregate, certain particles need to be screened; coarse aggregate can be used as it is. Solid volume percentage for grain shape met the KS standard, and concrete shape slightly improved due to abrasion. As for potential usability as admixture, the performance demonstrated satisfying result for both fresh and hardened concrete at replacement ratio of 10%, and fineness of 3000㎠/g and 4000㎠/g, leading to an interim conclusion that the material is suitable to be used as admixture.

Way that development result resources exhaustion of sudden industry and problem of environmental pollution use industrial wastes that is development and Industrial By-products of new Mineral Admixtures being risen development and examine. Because limestone powder chief ingredients is no damage to cement hydroxides as calcium carbonate and because Powder is very minuteness, viscosity is increase segregation of raw materials and capillary pore pouring effect, effect of watertightness is expected. Also, if limestone powder speech uses cement raplacing materials used of cement because is judged that is going to effect effect economical side and side of environmental pollution as curtailment limestone powder speech grasp concrete special quality to cement replacing materials principal parts data and it is purpose of this research that wish to foretell availability of use possibility.

The purpose of this study is to analyze concrete characteristics by admixing agent and additive contents according to the change of unit-water to identify its effect on compressive strength. First of all, as for flesh concrete, overall unit-water showed a tendency to decrease as component inclusion rate of admixing agent was increased. In addition, air content showed a tendency to increase by increasing WR, WB, NP series admixing agent contents, on the other hand, the change of air content was gentle by around 1.5±0.5% for S, T, M series agents. Bulk density showed an inverse proportion to the change of air content. As for hardened concrete, expression rate of 3-day age compressive strength was generally decreased for S, T, WR, WB, NP, M series admixing agent component. Also, expression rate of 7-day age compressive strength showed an excellent record for S, M series agents, and expression rate of 28-day age compressive strength showed a tendency to increase more than plain on the whole.

The results obtained from the experiments about the chemical compositions and the product quality of Lycium Chinense M?? and Chaenomels Sinensis K??? in Korea are summarized as follows: 1. The concents of proximate components of Lycium Chinense M?? were hgiher in the Jindo-products than that of the Kongju-products, except the content of crude protein of Jindo-products which was the least one(12.7%). 2. The content of Vitamine A, one of the special components of Lycium Chinense M???, was varied from 1.4mg% to 55.1mg%. It was thought because that samples were affected by the several factors during storage. 3. The Fe content of Lycium Chinense M??? of Jindo-products(11.2∼11.9mg%) was higher than that of Kong-ju-product.(6.6mg%) 4. Comparing the parched Lycium Chinense M??? with dried one, the contents of Vitamine A, volatile acid and total ester were decreased from 1.7 to 0.5mg%, 0.24 to 0.01mg% and 3.9mg% to 1.2mg%, respectively. But it was found that the contents of alkoloid and mineral were not changed. 5. In ungrafted seedling, the contents of the tested minerals except for phosphorous(18mg%) were higher than those of the other species. 6. The extracted powder tea was best according to the panel test. 7. There was no significant difference among the Lycium Chinense M??? liguors in taste, flavor and color. 8. By means of panel test on Chaenomeles Sinensis Koehne tea, the significant difference about taste and flavor of each sample was recognized and grinding fresh fruit sugared tea was the best.
