The needle renal biopsy has proved to be a valuable diagnostic method in many cases of renal diseases. The method is needed not only for the diagnosis through histopathological findings but also in obtaining materials for culture from the renal tissue. However, many complications have been reported after the procedure of renal biopsy; bleeding, pain, fever due to infection, arterio-venous fistula formation and urine leakage from the biopsied area etc. We devised a new technique using plug-form Gelfoam put into the biopsied site introduced through polycthylene tube right after Vim-Silverman needle application for the prevention of massive bleeding from the biopsied hole. This technique was applied in 25 cases of nephrolithotomy and ureterolithotomy, after renal exposure was performed. The bleeding time was also measured under the vision after above procedure was performed. The results were as follows: 1. The average bleeding times were from 2 min. to 8 min. 20 sec. after Gelfoan-plug introduction through the biopsied canal. 2. It is considered that the difference of bleeding time measured at two different site in the same kidney, mainly comes from the involvement of artery or vein and the size of these vessels. 3. The Duke's bleeding time and local bleeding time measured at the biopsied lesions were compared it was found that bleeding stopped earlier than Duke's bleeding time in 7 cases and in 19 cases delayed data was obtained. 4. No detectable complications were noted in the application of this method in our series.

The Ming and Qing Dynasties are the late period of modern Chinese development. With great changes in speech sound and many hot issues for academic research, it is an important transition phase from modern Chinese to contemporary Chinese. Therefore, the phonetic study in Ming and Qing Dynasties has become one of the research focuses for Chinese phonology study. Based on Lao Qi Da, a Chinese textbook used in Cho-Sun Dynasty of Korea, the paper discusses the Chinese phonetic evolution in three hundred years(1515~1795) during the Ming and Qing Dynasties by comparing the right annotated pronunciations in Lao Qi Da(1515) and Nokeoltae Eonhae(1795). 명청시대는 근대 중국어에서 현대 중국어로 넘어가는 중요한 과도기로 어음연구에 있어서 커다란 변화를 가져옴과 동시에 학술적으로도 관심을 많이 받기도 하였다. 명청시대 어음연구는 음운학 연구의 주관심 분야 중의 하나이다. 본고에서는 한국 조선시대의 중국어학습 교재인 『老乞大』를 사례로, 1515년에 편찬된 『飜譯老乞大』와 1795년에 편찬된 『重刊老乞大谚解』 두 저서의 우음(右音)에 대한 비교분석을 통하여 명청시대 즉 1515년에서 1795년까지 근 300년 동안의 중국어어음의 변천에 대해 고찰하고자 한다.
