Overbreak, underbreak and range of disturbed rock zone (DRZ) are the most important factors in evaluating the results of tunnel blasting. These factors, which depend on the discontinuities in rock mass, the blasting patterns and drilling conditions, have been studied. The range of DRZ can be estimated by relationships between vibration velocity and associated tensile stress. A new computerized rocket jumbo drill has been adopted to reduce overbreak based on the analysis of drilling accuracy. In-situ blasting tests were also performed by varying initiating systems. Overbreak can be reduce from 34.5cm to 20cm. The range of DRZ is 0.2m with stoping holes and 0.4m with wall holes respectively. In addition, some methods to reduce DRZ have been presented in this study.

The present study was conducted to investigate extraction characteristics and antioxidative activity of Schiznadra chinensis extracts. Schiznadra chinensis was extracted by reflux extraction(RE) under different extraction conditions including solvent. The solid yield, turbidity, color value, titratable acidity, free sugar contents, electron donating ability(EDA) and superoxide dismutase(SOD)-like ability of Schiznadra chinensis extracts were determined. The highest solid yield value was obtained with water of 10 fold. No significant difference in turbidity and color value were found among the extracts prepared with various extraction solvents, 75% ethanol, 50% ethanol and water. The highest titratable acidity was obtained with water extracts of Schiznadra chinensis. The free sugar contents of Schiznadra chinensis extracted with water showed the highest value. Schiznadra chinensis extracts with water included higher contents of free sugar compared with those of the other solvent extracts, 50% ethanol and 75% ethanol extracts. The total polyphenol compound content of Schiznadra chinensis extracted with 50% ethanol showed the highest value. Schiznadra chinensis extracts with 50% ethanol included higher contents of total polyphenol compound compared with those of the other solvent extracts, water and 75% ethanol extracts. The electron donating ability of extracts were 60.87% in water, 57.24% in 50% ethanol, and 55.61% in 75% ethanol.

This paper describes with an effect of a single- and a quadruple- lightning impulse currents on electrical characteristics of ZnO blocks, and an expert system to diagnose deterioration of arresters. In this study, an accelerated deterioration test is carried out to deduce the parameters needed for diagnosing arrester deterioration, and leakage current components are measured. Also, wave height distribution of the leakage current with the progress of arrester deterioration is analyzed. From the experimental results, the wave height distribution of the leakage current showed a conspicuous difference even in an immaterial leakage current increase. The use of wave height distribution of the leakage current in deterioration diagnostic technique makes more accurate diagnosis than the conventional method using only a leakage current value. Finally, the expert system based on the experimental reslts is developed, and the effectiveness of the system is estimated in a 18[kV] lightning arrester.

This study was carried out to evaluate the relations among working environments, health behaviors and satisfaction with their duty in a group of 200 ship-repair workers in the ROK navy. The results were as following; Age of workers was 40 years and over(83%) and working duration was 10 years and over (71.5%). Most of them were married and had studied beyond high school. The 69.5% of workers satisfied with their job, whereas. about 59.5% of workers had satisfaction with their working condition. There were current drinkers, 78.5%, current exercising workers, 43.5%, obese workers, 28.0%, and salted food intakers, 18.5% in the workers. The major harmful environmental factors in the ship-repair workplace are noise, vibration, dust and chemicals. Most of workers are exposed to above harmful factors and complained about exposure of noise and dust. The consumption of cigarette or alcohol in people who exposed to noise was much higher than in people who did not, but the difference was not statistically significant. Prevalence of obesity and hypertension were not significantly different between the exposure with noise and dust. Noise or dust exposure was significant relation to satisfaction with their duty and working condition. The affective factors for satisfaction with their duty were people who worked for 10 years or more(OR= 4.53), exercisers(OR=4.78) and dust(OR=3.05) in Logistic regression analysis.

Penetration of concrete by aggressive materials in solution may cause an undesirable effect on concrete durability, for instance when Ca(OH)₂ is being leached out or an attack by aggressive liquids takes place. In particular, carbonation occurs in concrete because the calcium bearing phases present are easily attacked by carbon dioxide and converted to calcium carbonate from surface of concrete, It has been known that the durability of reinforced concrete structure is concerned with the surface performance of concrete which affects on the carbonation occurred by invasion of CO₂ gas and the corrosion of steel bar occurred by O₂ In this paper, the effects of carbonation resistance by improvement of surface performance for concrete are investigated according to the accelerated carbonation test. It is believed that the carbonation resistance of concrete has been significantly improved by the application of penetrative hardening agent due to the formation of a dense surface.

Cordyceps species including Cordyceps bassiana are a notable anti-cancer dietary supplement. Previously, we identified several compounds with anti-cancer activity from the butanol fraction (Cb-BF) of Cordyceps bassiana. To expand the structural value of Cb-BF-derived anti-cancer drugs, we employed various chemical moieties to produce a novel Cb-BF-derived chemical derivative, KTH-13-amine-monophenyl [4-isopropyl-2-(1-phenylethyl) aniline (KTH-13-AMP)], which we tested for anti-cancer activity. KTH-13-AMP suppressed the proliferation of MDA-MB-231, HeLa, and C6 glioma cells. KTH-13-AMP also dose-dependently induced morphological changes in C6 glioma cells and time-dependently increased the level of early apoptotic cells stained with annexin V-FITC. Furthermore, the levels of the active full-length forms of caspase-3 and caspase-9 were increased. In contrast, the levels of total forms of caspases-3, caspase-8, caspase-9, and Bcl-2 were decreased in KTH-13-AMP treated-cells. We also confirmed that the phosphorylation of STAT3, Src, and PI3K/p85, which is linked to cell survival, was diminished by treatment with KTH-13-AMP. Therefore, these results strongly suggest that this compound can be used to guide the development of an anti-cancer drug or serve as a lead compound in forming another strong anti-proliferative agent.
