Insampaedoksan (IS) is the decoction of medicinal herbs, which was commonly used for anti-inflammatory and anti-pyretic in the Korean traditional medicine (KTM). Several studies on improving efficiency or searching new efficiency by fermenting traditional herbal medicines are recently in progress. The bioconversion has been conducted on IS using various bacteria. Liquiritin, ferulic acid, hesperidin, liquiritigenin, and glycyrrhizin in IS before and after fermented IS were simultaneously analyzed. These compounds were qualitatively analyzed and quantitatively analyzed using the HPLC-DAD system. The identifications of liquiritin, ferulic acid, hesperidin, liquiritigenin and glycyrrhizin were achieved by comparing the HPLC retention time ($R_t$) and the UV absorption of five pure compounds in the IS. As a result, the increased constituents were identified to be liquiritin, liquiritigenin and glycyrrhizin, while the decreased constituent was ferulic acid and the constituent of hesperidin was similar to before and after fermentation. Insampeadock-san fermented by Lactobacillus plantarum KFRI 144 exhibited the most remarkable changes in all of fermentation.

Objective : This study is designed to evaluate the clinical effect of the oriental medical treatment (Ex: chuna, physical theraphy, acupuncture, moxibustion, herb medicine, etc.) on patient of scoliosis. Methods : We investigated 12 patients with scoliosis who visited to Department of Acupunture & Moxibustion, Tae gu Oriental Hopital of Kyung San University from January 2000 to September. 12 patients had a diagnosis of scoliosis by X-ray. We treated 12 patients by the oriental medical treatment (Ex: chuna, acupuncture, physical theraphy, moxibustion, herb medicine, etc.)and they were evaluated with post treatment X-ray findings. Results : 1. We investigated 6 female and 6 male patients. The most commom distribution of age was 30's. 2. In the scoliosis angle : before treatment, the average scoliosis angle was $13.56^{\circ}$ but after treatment, it was decreased to $9.31^{\circ}$ and the mean correctability was 33.47%. 3. The more servious the symptoms were, the lesser the correction rate was. It was decreased in the order of Gr I, Gr II, Gr III and Gr IV. 4. The larger the scoliosis angle and the degree of rotation were, the lesser the correction rate was. Conclusion : These results suggest that the oriental medical treatment (Ex: chuna, acupuncture, physical theraphy, moxibustion, herb medicine, etc.) was effective treatment modality on patient of scoliosis.

In Chinese Mathematics, Jia Xian(要憲) introduced Zeng cheng kai fang fa(增乘開方法) to get approximations of solutions of Polynomial equations which is a generalization of square roots and cube roots in Jiu zhang suan shu. The synthetic divisions in Zeng cheng kai fang fa give ise to two concepts of Fan il(飜積) and Yi il(益積) which were extensively used in Chosun Dynasty Mathematics. We first study their history in China and Chosun Dynasty and then investigate the historical fact that Chosun mathematicians Nam Byung Gil(南秉吉) and Lee Sang Hyuk(李尙爀) obtained the sufficient conditions for Fan il and Yi il for quadratic equations and proved them in the middle of 19th century.

HPM(History and Pedagogy of Mathematics) become an important issue to us now. Study on old Korean mathematics books were made recently. We study mathematics books in Kyujanggak in this article. Horng Wann-Sheng 洪萬生, an math. historian and a member of editorial board of Historia Mathematica, visited Kyujanggak, the royal library of Joseon Dynasty. After his visit, he published a paper, "The first visit to mathematics books in Kyujanggak 奎章閣收藏算書初訪"(2008 Kyujanggak 32, p. 283-293). In his paper, he also raised several research problems on the history of Korean mathematics. In this paper, we analyze his paper "The first visit to mathematics books in Kyujanggak" and give some answers to those raised problems on Korean mathematics. Also we correct some misunderstanding of Horng on some facts. Especially, we make it clear that the author of SinJungSanSul(New Arithmetics 新訂算術) was not Lee Sang-Seol(李相卨), whom Horng considered as the author, but Lee Gyo-Seung(李敎承) through the correct translation of its preface and an article about its copyright lawsuit. And we added some pathways how Chinese mathematics books were imported by Joseon. We introduce the case of Hong Dae-Yong(洪大容) in detail.

We will provides a micro-pump infusion injector with the cloud networking for remote control. The existing infusion injector with controlled manually have an uncomfortable to use it inconveniently. The proposed remote control infusion, infusion system enables the identification and control of injected amount through the IOT function on th WEB. The micro-pump used is a piezo electric pump manufactured by using MEMS technology, and the amount of charge is varied depending on the frequency magnitude through the micro-controller. The micro-pump can adjust the speed of the fluid depending on the frequency and can be from 0.1ml / min to 7ml / min when the frequency is from 3 to 110Hz.

There are two transcriptions of "ChiJongBang" in Korea at the moment. The first is the Jangseo-gak ibrary transcription(K3-380). The title is "ChiJongBang(治腫方)" and it starts with the contents of "ChiJongBang(治腫方)", followed by "HoeChunYoGyeol(回春要訣)", "NoInSeopYangBang(老人攝養方)", "SoABang(小兒方)". "ChiJongBang(治腫方)" does not even take up a large portion of the book. The other transcription is "ChiJongBang(治腫方)" in Geojil's "Uihui(宜彙)", which was presented into the worldin 1871(the 8th year of King Go-jong)by GeumRiSanIn(錦里山人). The contents of the two transcriptions are the same, and both are left by ImEonGuk. The latter part is identical to the contents of "ChimGuGyeongHeomBang". It was common fora medical book to have additional useful information attatched in the end, so it was thought that somebody added a part of "ChimGuGyeongHeomBang" at the end of "ChiJongBiBang". But the discovery of a woodcut "ChiJongBang" in Korean annotation confirmed that the making of this book was led by the government, and the fact that abscess was a big part of healthcare around the ImJinWaeRan(Japanese Invasion of Korea in 1592) period.

This study was aimed to investigate the antibacterial efficiency of silver nano-particles and the dyeing properties of a brushed warp-knitted fabric. The properties of the brushed warp-knitted fabric containing silver nano-particle by field production processes were evaluated by analyzing its silver contents, antibacterial activity, color difference, exhaustion curve, fastness and tearing strength. Bacterial reduction ratio amounts to 91.4 and 99.9 for Staphylococcus aureus and Klebsiella pneumoniae respectively. As the brushed pile length of its fabrics is longer, the exhaution rate of disperse dye becomes higher. The brushing process of its fabrics reduces the tearing strength. The results indicate that the brushed warp knitted fabric containing silver nano-particle can be a practically promising product.

알코올 환원법(alcohol reducing process)은 화학적 환원제가 필요하지 않은 화학합성법으로 메탄올, 에탄올, 프로판올, 이소프로판올, 부탄올 등 C1-C4의 알코올류, 에틸렌 글라이콜, 디에틸렌 글라이콜, 프로필렌 글라이콜과 같은 글리콜류 등이 용매이자 환원제로써 사용된다. 전형적으로 금속 전구체를 상기의 알코올류나 글리콜류에 용해 또는 분산시킨 후 그 용액을 환류 조건하에서 가열하게 되면 금속 이온과 용매간의 산화, 환원반응에 의하여 금속이온이 금속원자로 환원되며, 환원된 금속 입자들은 핵 행성과 성장 과정을 거쳐서 입자를 형성하게 된다. 본 연구에서는 알코올환원법을 이용하여 나노크기의 은입자제조를 시도하였고, 이를 PET 칩과의 마스터배치 제조을 시도하였으며, 이의 항균성능을 연구 고찰하였다. 30 ~ 80 nm의 은파우더를 제조할 수 있었으며, 우수한 항균성능을 갖는 Ag/PET 마스터배치를 제조할 수 있었다. 이를 활용하여 나노은입자기반의 항균섬유을 제조하여 이를 활용한 기모경편성물 제조의 기초데이타로 활용이 가능하리라고 사료된다.

나노소재기술은 기존 소재로는 얻을 수 없는 새로운 기능 및 특성을 나타낼 수 있어 산업전반에 적용할 수 있는 최첨단집적기술이다. 그러나 나노입자를 섬유에 첨가하여 기능성 섬유를 생산하는 경우 응집이 발생하는 등의 다양한 문제점이 발생하는데 이를 극복하기 위해서는 사이즈 분포를 제어하는 기술, 표면처리를 통해 분산성을 향상시키는 기술, 나노입자와 섬유와의 상용성을 개선하는 기술 등이 해결되어야 한다. 본 연구에서는 고기능성 및 고부가가치 경편파일 니트 원단을 개발하기 위해 은(Silver) 나노입자가 균일하게 분산된 M/B(Master Batch)를 제조하였으며, 이를 PET와의 용융 혼합 방사함으로써 0.5denier(75D/144F)급 원사에 99.9%의 영구적인 항균/소취 기능을 부여하였다. 또한 개발된 극세사를 이용하여 다양한 경편파일 원단을 설계하고, 기모, 염색 및 날염 등의 공정을 거쳐 나노기술융합형 화학섬유소재를 이용한 기능성 침장 제품을 개발하였다.
