Blister beetles produce cantharidin, which is toxic to people and animals. Cantharidin has been believed to be an aphrodisiac and an abortifacient based on its tendency to cause marked irritation to the genitourinary system leading to priapism in men and pelvic congestion in women for many years. Cantharidin was used by oriental traditional medicine for more than 2000 years. Typical signs related to cantharidin ingestion are gastrointestinal tract and urinary tract irritation, endotoxemia, shock and myocardial dysfunction. Cantharidin is a severe irritant to epithelial linings (gastrointestinal tract, urinary tract, and skin) and develop systemic inflammatory response syndrome. We report a case of corrosive esophagogastritis and acute renal failure by ingestion of cantharidin.

The purpose of this study is to find out changing process of 'Kyungsung Libraries' in the Japanese colonial era by comparing and analyzing through the books and Journals of Korea and Japan. The subject scopes of this study are as follows ; 1) 'Kyungsung Libraries' in Japan Chamber of Commerce and Industry founded by Japanese named, 'San Gu Jung(Yamaguchi Sei)' 2) 'Kyungsung Libraries' founded by 'Yoon Ik Sun' in 'Chiwoonjung' 3) 'Kyungsung Libraries' founded by 'Lee Bum Sung' beside 'Jongno Tapgol Park'. This study studies each three libraries and simultaneously, relationship between mutual relation of these three libraries and other libraries. As a results, the books of San Gu Jung(Yamaguchi Sei)'s library were inherited to those of other two libraries. Also, Despite of eagerly practicing public service of the age, however, independent development of each of two library founded by Koreans was very limited under the influence of Japanese colonial.

현재 폭넓은 시장을 형성하고 있는 LED는 전 세계적으로 이슈화 되고 있는 친환경 조명기기로 각광받고 있으며, 향후 조명 산업의 50% 이상 시장 점유율을 차지할 것으로 예상된다. 본 논문에서는 Analog Dimming을 이용하여 Single-stage LED 구동 회로를 제안한다. 제안된 회로는 기존 방식과 달리 DC/DC단이 없으므로 가격 경쟁력 및 높은 전력 변환 효율을 확보할 수 있고, 고조파 규제 만족을 위한 역률 보정 기능이 있으며 휘도를 선형적으로 제어할 수 있는 Analog Dimming 기능을 가지고 있다. 최종적으로 제안된 Single-stage LED 구동 회로의 동작 및 Analog Dimming 제어 기법을 소개하고, 시뮬레이션 및 40W급 시작품을 제작, 동작 실험을 통하여 그 타당성을 검증한다.

Objectives : This study was designed to find out correlation of filtration rate of herbal-acupunctures and pain score of herbal acupuncture stimulation. Methods : Filtration rate of Hwangryunhaedoktang herbal acupuncture, Kidney yang deficiency number two herbal acupuncture, Hominis Placenta herbal acupuncture, Cervus Elaphus herbal acupuncture, BUM herbal acupuncture and Carthami Flos herbal acupuncture were measured at the korean institute of herbal acupuncture. And Hwangryunhaedoktang herbal acupuncture, Kidney yang deficiency number two herbal acupuncture, Hominis Placenta herbal acupuncture, Cervus Elaphus herbal acupuncture, BUM herbal acupuncture and Carthami Flos herbal acupuncture were injected at Xie points of the subjects. Results : Ranking of herbal acupunctures filtration rates is the same as ranking of pain score and duration time of herbal acupuncture. Correlation analysis result of herbal acupunctures filtration rates and herbal acupuncture VAS with a simple linear regression analysis is that correlation coefficient of Hwangryunhaedoktang herbal acupuncture, Kidney Yang Deficiency Number Two herbal acupuncture, Hominis Placenta herbal acupuncture, Cervus elaphus herbal acupuncture, BUM herbal acupuncture. Carthami Flos herbal acupuncture is 0.44, 0.53, 0.58, 0.76, 0.47 and 0.54. Correlation analysis result of herbal acupuncture's filtration rates and herbal acupuncture stimulation's duration time is that correlation coefficient of Hwangryunhaedoktang herbal acupuncture, Kidney Yang Deficiency Number Two herbal acupuncture, Hominis Placenta herbal acupuncture, Cervus Elaphus herbal acupuncture, BUM herbal acupuncture, Carthami Flos herbal acupuncture is -0.09, 0.11, -0.07, 0.28, -0.11 and -0.09. Conclusion : We found the correlation of filtration rate of herbal-acupunctures and pain score of herbal-acupuncture stimulation. This study help to control pain amount and pain duration time of herbal acupuncture treatment. And this study improve acupuncture theory of herbal acupuncture.
