In this paper, using the spectra and the reflection coefficient of surface acoustic wave:SAW, the surface breaking crack-depth is estimated by computer simulation and the experiment. In order to perform this experiment, two type shaped flows half-penny and rectangular of line-crack have been made in the surface of aluminium. Measuring results, for half-penny type, the reflection coefficient have been in proportion to the surface breaking crack-depth. When the spectrum analyzer was used, the spectra analysis method for line crack of rectangular type was measured the average deviation 8.7% to the surface breaking crack-depth.

Recently it is known renal medullar will be play a important role of blood pressure control and pressure natriuresis. Renomedullary antihypertensive mechanism is activated by increasing perfusion pressure of kidney and can be inhibited by sympathetic nerve stimulation or blockade of nitric oxide(NO) formation. It is important to know what is affect on renal regional blood flow, especially renal medullary blood flow(MBF). For the purpose of investigating the effect of the renal sympathetic nerve on regional blood flow during infusion of blocking NO synthesis(by N^(ω)-nitro-L-arginine methylester:L-NAME) in spontaneous hypertensive rat(SHR) and Wistar rats normal control, Mean arterial pressure(MAP), total renal blood flow(TRBF), midcortical blood flow(CBF), inner medullary blood flow were measured in innervated or denervated renal sympathetic nerve group of SHR and Wister rats. All group that received the L-NAME were seen increasing MAP while TRBF, CBF and MBF decreased and the decrease of TRBF in SHR is more marked than in Wistar rat. In spite of increasing the MAP, MBF in all four group decreased, respectively C: 220 ± 3 U, 205 ± 2 U Wi : 215 ± 4 U, 165 ± 12 U Wd :218 ± 3 U, 170 ± 10 U Si :195 ± 4 U, 98 ± 15 U Sd : 200 ± 3 U, 120 ± 14 U, especially the most remarkable decrease about 50 % in SHR innervated group. Thus, according to these result, NO seems to maintain the MBF and the partial interaction between renal sympathetic nerve and NO in medullary blood flow can be suggested in innervated SHR.

We came to the conclusion after considering all the information from many kinds of book on herb medicine which is treatment method of "quickening blood and transforming stasis" for external wound. 1.Angelicae sinensis Radix and Angelicae Gigantis Radix are account for 16%(57times) of monarch drug and ministerial drug in all. It means that effect of "quickening blood and transforming stasis" of Angelicae sinensis Radix and Angelicae Gigantis Radix are more excellent than any other herb medicine. 2.In the case of the monarch drug,Angelicae sinensis Radix and Rhizoma Rhei are used at most, treatment method is divided into "expel stasis" and "quickening blood and transforming stasis" 3.In the case of the monarch drug, there are Dolomitum, Eupolyphaga, Dracinis Resina, Crinis Carbonisatus, Acronychiae Ligum, Pini Ramulus etc which have strong treatment effect and pecunliar sort. 4.In the case of the ministerial drug, there are Dracinis Resina, Brassica Rapa, Pyritunm, Liquidambaris Resina etc which are unusual sort. 5.In the order of frequency in use of monarch drug and ministerial durg in nature, it is hot, mean, cold drug. In the order of frequency in use of monarch drug and ministerial drug in flavors, it is sharp, pungent, sweat.

토끼 바이러스성 출혈증의 원인체를 실험 토끼에 접종하여 증식을 유도하고 간장에서 hematoxylin & eosin 염색에서 조직학적 진단과 세포내 viral RNA의 소재를 결정하기 위해 post-unicryl 포매한 block의 절편을 사용하여 단 염색과 전자현미경적 in situ hybridization을 시도하였다. 토끼 출혈증 viral RNA의 보합 결합에 이용하는 probe는 4717에서 4800(84bases)까지 oligonucleotide를 5'말단에 biotin-CE phosphoramidite로 표지하여 사용하였다. 보합결합물의 증명은 신호 표지로서 antibiotin antibody-10mm gold를 사용하였으며, hubridization이나 증명은 기존 protocol에서 약간의 변법을 사용하였다. 0.02% glutaraldehyde에서 고정하고 unicryl resin 포매한 표본, biotinylated oligonucleotide probe, antibiotin antibody-10mm gold로 실험한 결과 증강된 신호를 얻을 수 있었다. 특히 전처리를 생략하므로써 실험 과정을 간단하게 하여 신속한 결과를 얻을 수가 있었다. 전자현미경 in situ hybridization을 통하여 토끼 출혈증 바이러스의 주요 표적은 간세포로 간염 세포의 세포질 내 미토콘드리아와 핵사이에서 immuno gold입자가 뚜렷하게 표지됨으로서 viral RNA를 증명할 수 있었다. Simple stain and electron microscopic in situ hybridization is studied and applied for the identification of rabbit haemorrhagic disease viral RNA in a unicrylated preparation of the liver after innoculation of rabbit haemorrhagic disease virus. Hybridization for detection of viral RNA in unicryl embedded tissues using complementary 84 bases oligonucleotide probe labelled by biotin CE-phosphoramidite compared with 4717∼4800 sequences of rabbit haemorrhagic disease virus, modified hybridization protocol and antibiotin antibody-l0nm gold as signal marker. The best results were obtained in 0.02% glutaraldehyde, Unicryl resin cell block, biotinylated oligonucleotide probes, antibiotin-l0nm gold. In this report, RHD viral RNA was distributed widely within the mitochondria and nucleus of liver cell by electron microscopic in situ hybridization. In situ hybridization has become a standard method for localizing DNA or RNA sequences in tissue or cell preparation. In situ hybridization is detected the virus genome in the cells and tissue as specifically compared with others nucleic acid hybridization method.

This paper has analysed and associated present condition, type and cause of Korean traffic accidents with a violent driving, and examined drives's condition of Conciousness through questionnaire-subject to 471 persons of Drivers. After total analyses, it could be sought that Quantative decrease of traffic accidents can be decreased with enlightment, national education and improvement of institution and facilities in spite of increase of traffic volume, and I've suggested some alter natives.

The groundwater levels at 5 sites, the ve.rtid variations of the electric cmductivity at 7 sites and the water quality of the groundwater at 11 sites were measured to study the charactmistics of the groundwater levels' fluctuations and occurrence of eastnorthem part Cheju Island. The result of examination of subsurface geologic structure of the Kujwa area from core logging shows that the area does not have the Seoguipo Formation that acts an aquiclude in the Shinchon area by preventing the downward flow of the hroundwater, In addition, the result also shows that the thickness of basaltic flows below the mean sea level in the Kujwa area is much larger than that the Shinchon area, and this suggests that the Kujwa area moved downward bu sunsidence. The groundwater levels at Kimyong and Kujwa areas occurred in response to oceanic tides. The tidal effect on the groundwater levels upon the distance from seashore. However, structure of the Kujwa area The result of examination of suMace lnnuenced by the amount of precipitation The groundwater qualities of the Kujqa area characterized by Na-Cl type, and that of the Shinchon area by Na-HCO₃type, The electric conductivity peofiles of the groundwater, the Kujwa area is increase with water depth, but Shinchon area is on the decrease or uniformly with water depth, Thes dofference indicates that the groundwater of both areas has different origin and different geologic environments.

A 26 year old lady was admitted due to fever and productive coughing of 10 days duration. She had been working at the office treating stuffs of oriental herb medicine without any problem in her health by then. Chest films revealed consolidative changes involving Lt. lower lobe and she was given systemic antibacterial antibiotics, but her illness was not improved. On 19th hospital day needle biopsy was performed and cryptococcosis was diagnosed involving both alveoli and intertitium. Antifungal agent, itraconazole, was prescribed for 10 weeks and the lesion was resolved completely without remnant change. We discussed this case with review of literatures.
