식물혈구응집소 Sanguisorba Officinolis. L.가 실혈가토의 조혈기능에 미치는 영향
정성화,백승룡 최신의학사 1975 最新醫學 Vol.18 No.1
Sanguisorba Officinolis L (S. 0. L.) has been known to possess phytohemagglutin activity. This experimental study is undertaken to evaluate whether S. 0. L. has effect on hematopoietic activity in rabbit. Each rabbit of experimental group was injected 1.0ml of S.O. L. extract intravenously just after bleeding, and studied peripheral blood in R.B.C. count, hematocrit count, hemoglobin, reticulocyte count, total W. B. C. count, lymphocyte and granulocyte count. The result obtained are as follow: 1. Interval of recovery in erythrocytic series was shortened by S.O. L. injection after bleeding. 2. Higher level of peripheral leukocyte count in early stage was noted by S.O.L. injection after bleeding. 3. Higher level of peripheral leukocyte count was due to increased lymphocyte count. S. 0. L. seems to possess activities to stimulate the bone marrow hematopoiesis and the lymphopoiesis.

This article is a historical record of a Polish political prisoner, Mikhail Ivanovich Yankovsky (1842-1912), who left a large footprint in the Siberian development during the second half of 19th century Russia. As a university student, Yankovsky participated in January Uprising of 1863 against the authoritarian regime of Russia. The uprising was unsuccessful and resulted in loss of his noble status and wealth as well as forced labor for 8 years in Siberia. Yankovsky became a mine expert during his time in Siberia and later became a pioneer of the Siberian development after he was freed. The Russian government began to accelerate its development in the Siberian region since the late 19th century. Due to lack of trained professionals in Siberia, the government had to employ the political prisoners who had extensive science knowledge, such as Yankovsky, in East Siberian Branch of the Russian Geographical Society to expedite its expedition and research of the region. Years of experience as a miner helped him settle as a manager of a gold mine in Askold Island, which is located 50 kilometers away from Vladivostok. In 1877, Yankovsky discovered Sidemy Penninsula, located 20 miles south of Vladivostok. Sidemy was a region yet to be introduced to the west, occupied by the aborigines, Chinese, and Koreans. Yankovsky was able to obtain a long-term lease contract through Gustav F. Erdman (1818-1883), a regional military governor. Yankovsky was able to start a horse farm while fighting off the wild animals and Chinese horse thieves. This also resulted in protection of the Korean immigrants in the region and the Yankovsky family received great respect and trust from the community. The successful management of the horse farm resulted in significant accumulation of wealth as well as contribution to the regional development. Upon Mikhail Yankovsky’s death in 1912, the horse farm was taken over by the eldest son Yury Yankovsky and continued to florush.

고분자막을 사용하여 알카리 금속 이온에 대한 선택 투과성 연구를 수소 이온의 능동 수송의 드라이빙 포오스로 이용한 실험 결과를 보고 한다. 생체 현상인 능동 수송에 대한 연구는 Cussler 와 Evance의 보고 이후 에네지 개발의 일환으로 연구는 활발하다. 본 연구도 능동 수송의 현상을 자체 에네지로 대체하는 목적에 초점을 맞추어 네른스트의 막 전위식과 Fick 의식으로 실험 결과의 해석을 보고 한다. 사용한 고분자 막은 일본 토쿠 야마 소오다 제품을 컨디션닝 하여 사용 하였다.
일시적인 시각차단이 만성 뇌졸중 환자의 지면 족저압 분포와 족부면적에 미치는 영향

Purpose: The purpose of this study was to investigate the effect of temporary visual block existence and nonexistence on the change in foot pressure and foot area in stroke patients. Methods: Sixty-one chronic stroke patients volunteered to participate in the study. Foot pressure and foot area were measured using the Biorescue system. The subject maintain a comfortable standing position on the pressure-measuring plate one meter away from the computer. The sequence of the visual variation data while standing on the measuring plate was collected randomly. The data were collected with three repetitions and used the five-second measuring values except the first second and the last second according to each visual condition. All data were analyzed using SPSS version 21.0. The significance level for the statistical inspection was set as 0.05. Results: The comparison between the visual existence and nonexistence status showed statistically significant effects on foot pressure and foot area. The visual nonexistence status showed more improvement in foot pressure symmetry and area than visual existence status. Conclusion: This study shows that the foot pressure and foot area for the chronic stroke patients changed according to the visual states. It is predicted that these data will be used in rehabilitation training programs and to present temporary changes in visual status for stroke patients.
Size Control of Silicone Particles Using Sonochemical Approaches
정성화,유기천,황영규,Jong-San Chang* 대한화학회 2007 Bulletin of the Korean Chemical Society Vol.28 No.12
Particle size of silicones can be controlled by changing the reaction conditions such as temperature and concentrations of water and tetramethoxysilane (TMOS). Alternatively, the use of ultrasound radiation is also an elegant technique to decrease the particle size. Small silicone particles can be obtained at low temperature from diluted reagent containing TMOS, especially under the powerful ultrasound radiation. The size control may be explained by the rate of particle growth rather than that of nucleation.
