  • Gang Myeong-gil(康命吉) wrote Jejung sinpyeon(濟衆新編), one of three major medical books produced in the latter half of the Joseon Period. Jejung sinpyeon, edited at the behest of King Jeongjo, was intended to overcome the shortcomings of the then best medical book, Donguibogam(東醫寶鑑), and to update medical knowledge in a bid to spread that knowledge widely to the general public. Jejung sinpyeon contains the life and medical theories of the physician Gang Myeong-gil. In order to examine Gang Myeong-gil's life and medical theories, which influenced the edition and characteristics of Jejung sinpyeon, this paper studies his family lineage, medical records and the editorial characteristics of Jejun sinpyeon. Gang Myeong-gil and his ancestors served in government medical offices for some 200 years, and Gang Myeong-gil himself served as a physician at Naeuiwon for thirty years. His descendants also served as physicians upon passing the state-administered examination. Gang Myeong-gil preferred to prescribe drugs, and this inclination led him to include Yakseongga in Jejung sinpyeon, and he took an open and practical attitude towards the editing of the book. This approach is supported by the chapter on experience-based prescriptions in Jejung sinpyeon and the prescriptions of the Royal Infirmary, thus revealing his humanitarian and open thinking on medicine.

  • 국회에서의 국방예산안 심의과정에서는 예년에 비교할 수 없을 정도로 심층깊은 논의가 이루어졌을 뿐만 아니라 율곡예산에 대해서도 세부적인 질의와 검토가 이어짐으로써, 향후에는 예산소요에 대한 명확한 근거와 논리가 뒷받침되지 않고는 적정수준의 국방비 획득이 결코 용이하지 않을 것임을 예고하였다.

  • Jejoongshinpyeon was published in 1799 by 康命吉 upon receiving orders from the king. This book is a critical accedence of Treasured Mirror of Oriental Medicine and aims to enunciate summarized medical knowledge. Through examining citation methods in Jejoongshinpyeon, the following conclusions could be reached: First, citation methods displayed in Jejoongshinpyeon is largely based on Treasured Mirror of Oriental Medicine. Second, the specific method of citing Treasured Mirror of Oriental Medicine involves collecting and describing annotations from different titles.. Third, Jejoongshinpyeon cites other medical texts by making additions to symptoms or prescriptions not included in Dongeuibogam.

  • Cu2ZnSn(S,Se)4 thin film solar cells have been fabricated using sputtered Cu/Sn/Zn metallic precursors on Mo coated sodalime glass substrate without using a toxic H2Se and H2S atmosphere. Cu/Sn/Zn metallic precursors with various thicknesses were prepared using DC magnetron sputtering process at room temperature. As-deposited metallic precursors were sulfo-selenized inside a graphite box containing S and Se pellets using rapid thermal processing furnace at various sulfur to selenium (S/Se) compositional ratio. Thin film solar cells were fabricated after sulfo-selenization process using a 65 nm CdS buffer, a 40 nm intrinsic ZnO, a 400 nm Al doped ZnO, and Al/Ni top metal contact. Effects of sulfur to selenium (S/Se) compositional ratio on the microstructure, crystallinity, electrical properties, and cell efficiencies have been studied using X-ray diffraction, Raman spectroscopy, field emission scanning electron microscope, I-V measurement system, solar simulator, quantum efficiency measurement system, and time resolved photoluminescence spectrometer. Our fabricated Cu2ZnSn(S,Se)4 thin film solar cell shows the best conversion efficiency of 9.24 % (Voc : 454.6 mV, Jsc : 32.14 mA/cm2, FF : 63.29 %, and active area : 0.433 cm2), which is the highest efficiency among Cu2ZnSn(S,Se)4 thin film solar cells prepared using sputter deposited metallic precursors and without using a toxic H2Se gas. Details about other experimental results will be discussed during the presentation.
