  • Major symptoms of al1ergic rhinitis are nasal obstruction, sneezing and watery rhinorrhea. Onpyetang has been used to treat for nasal obstruction, which is one of the symptoms of allergic rhinitis. This Experimental study was done to research effects of Onpyetang and transformed Onpyetang(Allii Radix is deducted from Onpyetang) on the anti-allergic effects. We have studied the vascular permeability response induced by serotonin and histamine, the contact dermatitis response induced by picryl chloride, the delayed type hypersensitivity response to SRC, the mice paw edema induced by carrageenin, the writhing syndrome induced by $0.7\%$ acetic acid, and the rectal temperature in febrile rats induced by yeast. The results were as follows : 1. In the vascular permeability response to intradermal serotonin and histamine. Onpyetang proved significant inhibitory effect(P<0.05, p<0.001) But transformed Onpyetang proved significant inhibitory effect only to histamine(P<0.05) 2. In the contact dermatitis response induced by picryl chloride, Onpyetang and transformed Onpyetang proved significant inhibitory effect.(P<0.05, P<0.05) 3. In the delayed type hypersensitivity response induced by SRC, Onpyetang and transformed Onpyetang proved significant inhibitory effect on mice paw edema.. (P<0.05, P<0.05) 4. In the delayed type hypersensitivity response induced by SRC, Onpyetang proved significant inhibitory effect to serum IgE.(P<0.01) But transformed Onpyetang proved insignificant inhibitory effect on serum Ig E. 5. In the mice paw edema induced by carrageenin, Onpyetang and transformed Onpyetang proved significant anti-inflammatory effect. (P<0.01, P<0.01) 6. In the writhing syndrome induced $0.7\%$ acetic acid, Onpyetang and transformed Onpyetang proved significant analgestic effect. (P<0.01, P<0.01) 7. In the rectal temperature in febrile rats induced by yeast, Onpyetang and transformed Onpyetang proved significant anti-pyretic effect.(P<0.001, P<0.01) according to this result Onpyetang was conclude to be effective on anti-allergic, anti-pyretic, anti-inflammatory and analgestic action. but transformed Onpyetang(Allii Radix is deducted from Onpyetang) was not effective on the vascular permeability response to intradermal serotonin and increasing Ig E of delayed type hypersensitivity response induced by SRC. In addition, transformed Onpyetang is not effective as Onpyetang. More study should be done about the role of Allii Radix.

  • In this thesis, the relationship between the load carrying capacity and the transformed impact factor of the highway bridges were studied. The bridges are classified according to superstructures type. The result of the comparison between the load carrying capacity and the transformed impact factor, if the load capacity ratio of 0.57, the transformed impact factor was less in order of RC T-beam bridge, RC slab bridge, PC beam bridge, I-beam bridge. By the regression analysis on these results, the empirical formulae to predict the the load carrying capacity of bridge were suggested.

This study is to analyze the basic type, transformed type of street facade and also the meaning in the modern housing history. It analyzes basic elements(building elevation, gate, fence) and subsidiary elements(roof form, door, window), and the type of street facade by the composition of the element.

  • Cloning and expression of two different crystal protein genes from transformed Bacillus thuringiensis were investigated. B. thuringiensis NT0423 is toxic to both Lepidopterous and Dipte-rous larvae. The pCG5 vector carrying crystal protein genes (mosquitocidal and hemolytic activity) of B. thurigiensis subsp. morrisoni PG-14 was transformed into B. thurigiensis NT0423. Transformant has expressed two type crystals of bipyramid from NT0423 and ovoid from pCG5 in one cell.

  • In a two-stage two-level balanced nested design, type I error rates for the parametric tests and the rank transformed tests for the main effects and the nested effects are in overall similar to each other. Furthermore, powers for the rank transformed statistic for the main effects and the nested effects in a two-stage two-level balanced nested design are generally superior to powers for the parametric statistic When the effect size and the sample size are increased, we can find that powers increase for the parametric statistic and the rank transformed statistic are dramatically improved. Especially for the case of the fixed effects in the asymmetric distributions such as an exponential distribution, powers for the rank transformed tests are quite high rather than powers for the parametric tests.

  • In this research, fretting tests were conducted in air to investigate the wear characteristics of fuel cladding materials with the fretting parameters such as normal load, slip amplitude, frequency and the number of cycles. A high frequency fretting wear tester was designed for this experiment by KAERI. After the experiments, the wear volume and the shape of wear contour were measured by the surface roughness tester. Tribologically transformed structures(TTS) were analysed by means of optical and scanning electron microscopes to identify the main wear mechanisms. The results of this study showed that the wear volume were increased with increasing slip amplitude, and the shape of wear contour was transformed V-type to W-type. Also, it was found that the critical slip amplitude was 168${\mu}{\textrm}{m}$. These phenomena mean that wear mechanism transformed partial slip to gross slip to accelerate wear volume. The wear depth increased with an increase of friction coefficient due to increase of normal load and frequency. The fretting wear mechanisms were believed that, after adhesion and surface plastic deformation occurred by relative sliding motion on the contact between two specimens, TTS creation was induced by surface strain hardening and wear debris were detached from the contact surface which were produced by the micro crack propagation and creation.

  • Production of eight avermectin components was improved in Streptomyces avermitilis wild type strain (ATCC31267) and high producing mutant strain (ATCC31780) when transformed with a foreign regulatory gene, afsR2 of Streptomyces lividans. Wild type and the high producing strain of S. avermitilis transformed with multiple copies of afsR2 improved total avermectin productions by 2.3 fold and 1.5 fold, respectively. In both of wild type and the high producing transformants carrying afsR2, glycerol was proved to be the best carbon source for the stimulation of avermectin production.

  • Nondestructive eddy current testing has been used for measuring the electromagnetic properties of metals. It is well known that the conventional eddy current sensors are not effective to measure multi-layer properties. In this paper, the mutual inductance type sensor is studied and transformed fractions of metals are measured. Characteristic factors in eddy current testing are considered and their influences on the testing results are investigated.

  • Water waves propagate over irregular bottom bathymetry are transformed by refraction, diffraction, shoaling, reflection etc. Principal factor of wave transform is bottom bathymetry, but in case of current field, current is another important factor which effect wave transformation. The governing equation of this study is develope as wave-current equation type to investigate the effect of wave-current interaction. It starts from Berkhoff's(1972) mild slope equation and is transformed to time-dependent hyperbolic type equation by using variational principal. Finally the governing equation is shown as a parabolic type equation by splitting method. This wave-current model was applied to the kwangan beach which is located at Pusan. The numerical simulation results of this model show the characteristics of wave transformation and flow pattern around the Kwangan beach fairly well.
