Lee, H. S. Effects of anaerobic exercise on circulating leukocytes, reactive oxygen species production in neutrophilis and lactate concentration in human. Exercise Science, 21(2): 263-270, 2012. The purpose of this study was to investigate the effects of anaerobic exercise on circulating leukocytes, reactive oxygen species production in neutrophilis and lactate concentration in human. All subjects (n=10) was performed cycle ergometer anaerobic exercise (10 seconds . 5 sets, rest for 50 seconds between each set) at load intensity 0.075 kp per weight. Changes in circulating leukocyte numbers, reactive oxygen species (ROS) production in neutrophilis, ROS per neutrophilis, red blood cell, neutrophilis, band form, segmented leukocyte, Hb, Hct, MCV and lactic acid was measured before, immediately after, 30, 60 and 120 minutes after the cycle ergometer anaerobic exercise. circulating leukocyte number and reactive oxygen species production per neutrophilis were significantly increased immediately after (p=.038) and after 120 minutes of anaerobic exercise (p=.035, p=.027 respectively) compared with before anaerobic exercise. Neutrophilis (p=.029), band form (p=.029), segmented leukocyte (p=.032), and reactive oxygen species production in neutrophilis were significantly increased after 120 minutes (p=.039) of anaerobic exercise compared with before anaerobic exercise. Lactic acid was significantly increased immediately after (p=.021) and after 30 minutes (p=.041) of anaerobic exercise compared with before anaerobic exercise. These results confirmed that anaerobic exercise increase reactive oxygen species production in neutrophilis.

This paper is based on a study of the response characteristics of photoelectric type smoke detector chambers according todust color. Due to an amendment to the Fire Safety Codes to automatic fire alarm systems and visual alarm device, theinstallation of indoor smoke detectors has become mandatory, but in Korea there is still insufficient research on thenon-operation or false alarms that could arise in indoor environments by indoor dust and other environmental conditions etc. In light of this, for this study, research was conducted on the indoor adaptability of smoke detector under various colors offiber dust that were judged to occur most frequently in among the common indoor dust, photoelectric smoke detector withthe lattice-type smoke detection chamber that the smoke detector which is most popular in the country was used, and fourcolors of fiber dust (brown, white, gray and black) were used the test dusts for carrying out dust and sensitivity testing. Also,the voltage of the photocell part of the smoke chamber was measured, and the scattering phenomenon in the chamber wasobserved. The result of the testing showed that all four dust types were suitable for dust and sensitivity testing underconditions of pollution A. Yet, there were occasions, at pollution B or C, where the brown, white and gray dust would causefail alarm during operation testing. And black dust was confirmed to cause non-operation during operation testing. In the caseof brown and white dust, the voltage measurement result of the photocell part of the smoke chamber confirmed that thevoltage increases as the pollution level increases, and in the case of gray and black dust, the voltage decreases. 본 논문은 분진 색상에 따른 광전식연기감지기 챔버의 응답특성에 관한 연구이다. 국내 자동화재탐지설비 및 경보설비의 화재안전기준의 개정으로 연기감지기의 실내 적용이 의무화되었으나, 아직까지 국내에서는 실내 환경에서발생되는 실내먼지 및 환경조건 등에 의해 발생될 수 있는 부작동 및 비화재보에 대한 연구가 미비한 편이다. 이에본 연구에서는 실내먼지 중 가장 많이 발생될 것으로 판단되는 다양한 색상의 섬유분진에 따른 연기감지기의 실내적응성을 연구하기 위해 국내에 가장 많이 보급화 되어 있는 격자형의 연기챔버를 가진 광전식 연기감지기를 실험대상으로 하고, 갈색, 백색, 회색, 흑색 4종류의 섬유분진을 실험분진으로 하여 분진시험 및 감도시험을 진행하였다. 또한, 연기챔버의 수광부 전압을 측정하여 챔버 내부의 산란현상을 관찰하였다. 실험결과 4종류의 분진 모두 오염도A에서는 분진시험 및 감도시험에서 모두 적합한 것으로 나타났다. 반면, 오염도 B와 C에서는 갈색, 백색, 회색분진의 경우 작동시험 및 부작동시험에서 분진오염에 의한 오작동이 나타났고, 흑색분진의 경우 작동시험에서 부작동이발생되는 것으로 확인되었다. 연기챔버의 수광부 전압측정 결과는 갈색 및 백색분진의 경우 오염도가 증가할수록전압이 증가하였고, 회색 및 흑색분진의 경우 전압이 감소하는 것을 확인하였다.

WC-Co계 초경합금의 고온 산화

이호성 영남이공대학 산업기술연구소 1989 産業技術硏究 Vol.3 No.-

The oxidation behavior of sintered WC-Co was studied in air atomsphere at high temperature 800℃. The oxidation rate was meausured for weight changes of specimens by T. G. A. ν binder phase, rich cobalt phase, in which the solubility of carbon was small oxidized very rapidly as WC phase did. The oxidation rate of WC-Co was found to follow familiar linear rate law with formation of porous oxide, caused by CO, CO₂. Since these broke up the oxide film.

액상소결에서 Milling이 입자성장에 미치는 영향

이호성,김광수 영남이공대학 1989 論文集 Vol.18 No.-

The growth of solid grains during liquid phase sintering was investigated by ball milling with fine and coarse WC powders. Fine WC powders were more difficult to be crushed than coarse ones. When coarse and fine tungsten carbide powders are milled to give an identical averge particle size, the solid crystal size of sintered structure, obtained from the original coarse powder, is larger than that obtained from the original fine powder. Because the coarse grains would row at divergence in grain size due to the wider particle size distribution of original coarse powders after milling.

Visualization of the Network of Primo Vessels and Primo Nodes Above the Pia Mater of the Brain and Spine of Rats by Using Alcian Blue

이호성,Byung-Cheon Lee 사단법인약침학회 2012 Journal of Acupuncture & Meridian Studies Vol.5 No.5

By spraying and injecting Alcian blue into the lateral ventricle, we were able to visualize the network of the nerve primo vascular system above the pia mater of the brain and spine of rats. Staining these novel structures above the pia mater with 40,6-diamidino-2-phenylindole demonstrated that they coexisted in cellular and extracellular DNA forms. The cellular primo node consisted of many cells surrounded by rod-shaped nuclei while the extracellular primo node had a different morphology from that of a general cell in terms of DNA signals, showing granular DNA in a threadlike network of extracellular DNA. Also, differently from F-actin in general cells, the F-actin in the primo vessel was short and rod-shaped. Light and transmission electron microscopic images of the PN showed that the nerve primo vascular system above the pia mater of the brain and spine was a novel dynamic network, suggesting the coexistence of DNA and extracellular DNA. Based on these data, we suggest that a novel dynamic system with a certain function exists above the pia mater of the central nerve system. We also discuss the potential of this novel network system in the brain and spine as related to acupuncture meridians and neural regeneration.
