Nitrogen ion with various levels of dose and irradiation energy was irradiated on aluminum surfaces. Contact angle of surface was increased and surface color was changed by nitrogen ion implantation. During steam condensation experiment using nitrogen ion implanted specimen, dropwise condensation initially occurred on specimens. However, condensation mode eventually changed into filmwise condensation. The color of the surface was also changed from yellow-brown to silver-white. This change of surface color and condensation mode were results of hydrolysis reaction between condensate and nitrogen ion implanted on aluminum surfaces.

연약지반 및 사면 안정에 대한 강도증가를 위해 사용하는 시멘트로 인하여 경화도의 높은 증가를 기대할 수 있다. 하지만 시멘트를 사용함으로 인하여 시멘트에 함유된 유독물질인 Cr6+으로 인한 토양의 2차 오염 확산과, 경화도 효과에 따른 시멘트의 소비량 및 시멘트 생산 시 발생하는 이산화탄소 배출량이 가장 많은 것으로 지적받고 있어 시멘트사용의 저감과 이산화탄소의 발생을 줄이는 기술개발이 필요하다. 따라서 본 연구에서는 지중에 존재하는 미생물의 생체광물형성작용으로 생성된 탄산칼슘으로 지반의 고결화(solidification)작용을 일으켜 시멘트의 사용을 대체하면서, 성토나 절토사면의 친환경적 보강은 물론이고 전국적으로 15,000여개소가 존재하는 것으로 알려진 농업용 흙댐의 유지보수 등에 적용하고자 하는 것을 목적으로 하고있다. 이에 본 연구에서는 생체광물형성작용으로 탄산칼슘을 생성시키는 미생물인 Bacillus pasteurii균을 이용하여 미생물의 대사활동에 의해 생성된 광물질인 탄산칼슘으로 지반을 고결시키는 효과를 구명하고자, 실내실험이 용이한 모래를 대상으로 기본적인 실험을 수행하였다. 실험에서는 표준사와 일반모래 2종류를 상대밀도 30%, 60%로 5cm x 5츠 x 5cm의 정육면체 아크릴 상자에 채워넣고, Bacillus pasteurii균 50ml 을 주입하여 공시체를 성형하였다. 10일 그리고 20일이 지난 시료에 대해서 압축강도 실험과 CaO함량 분석, 새롭게 형성된 광물질(탄산칼슘)을 확인하기 위한 전자현미경(SEM)분석, X선 회절분석(XRD)을 실시하였다.

김성원(Kim SungWon),이병욱(Lee ByungWook),김기욱(Kim KiWook) 한국의사학회 2020 한국의사학회지 Vol.33 No.1

목적: 『동의수세보원』 辛丑本 ｢新定太陰人病應用要藥二十四方｣에 기재된 처방과 중요 고문헌에 기재된 처방의 본초 구성을 비교한다. 태음인 처방 본초 구성 패턴 포함 여부를 확인하였다. 방법: 신축본 태음인 처방과 『景岳全書』、『廣濟秘笈』、『東醫寶鑑』、『方藥合編』、『壽世保元』、『醫學入門』、『濟衆新編』、『鄕藥集成方』 처방의 본초 구성을 DB에 입력하고, 본초의 有無로 태음인 처방의 본초 조합 패턴을 포함하는 처방을 찾았다. 결과: 辛丑本 태음인 처방(가감 포함, 단미제 제외 24首) 중 葛根解肌湯、調胃升淸湯、淸心蓮子湯、麻黃定喘湯、熱多寒少湯、葛根承氣湯、葛根大承氣湯、葛根小承氣湯、麻黃發表湯、補肺元湯、鹿茸大補湯、拱辰黑元丹、皂角大黃湯、葛根浮萍湯、石菖蒲遠志散、麥門冬遠志散、牛黃淸心元의 17가지 처방은 중요 고문헌에 비슷한 용례가 있었고, 乾栗蠐螬湯、乾栗樗根皮湯은 東武公이 독창적으로 설정한 조합이다. 결론: 辛丑本 태음인 처방의 70.8%는 조선시대(명청시기) 문헌에서 용례를 찾을 수 있었기에, ‘태음인 처방을 송·원·명의 의가들이 더욱 연구하여 절반쯤 상세하게 밝혔다’라는 동무공의 견해에 부합된다. Purpose : This study compares prescriptions in the 1901 edition of the Donguisusebowon (東醫壽世保元) and the 1901 edition of 24 Revised Tae-eum constitution prescriptions (新定太陰人病應用要藥二十四方) (1901PCDT) with medical herbs found in classical texts. This study also examines whether to include patterns which compose medical herbs for the person of Tae-eum constitution (太陰人). Method : The prescriptions for Tae-eum-in in the Shinchukbon and the ingredients of medical herbs of the prescriptions of the Complete Works of Zhang Jingyue (景岳全書), Secret Works of Universal Benefit (廣濟秘笈), Treasured Mirror of Eastern Medicine (東醫寶鑑), Comprised Edition for Formulas (方藥合編), Protecting Essence for Longevity (壽世保元), Introduction to Medicine (醫學入門), New Book for Saving People (濟衆新編 ENGLISH), and Compendium of Local Medicinals and Formulas (鄕藥集成方) were input into a database. The prescriptions were examined and combinations of medical herbs used to treat the person of Tae-eum constitution were noted. Result : Among the prescriptions for the person of Tae-eum constitution, similar examples of the 17 prescriptions of Kudzu Decoction to Relieve the Muscles (葛根解肌湯), Regulate the Stomach and Coordinate the Purity Decoction (調胃升淸湯), Clear the Heart and Lotus Pip Decoction (淸心蓮子湯), Decoction for Stabilizing Asthma with Ephedra (麻黃定喘湯), Profuse Heat and Sparse Cold Decoction (熱多寒少湯), Decoction for Coordinating Qi with Kudzu (葛根承氣湯), Major Decoction for Coordinating Qi with Kudzu (葛根大承氣湯), Minor Decoction for Coordinating Qi with Kudzu (葛根小承氣湯), Decoction for Dispersing the Exterior with Ephedra (麻黃發表湯), Boost the Lung Essence Decoction (補肺元湯), Major Supplementing Decoction with Deer Antler Velvet (鹿茸大補湯), Boosting Black Essence Pill (拱辰黑元丹), Honeylocust Fruit and Rhubarb Decoction (皂角大黃湯), Kudza and Duckweed Decoction (葛根浮萍湯), Sweet Flag and Polygala Powder (石菖蒲遠志散), Liriopis and Polygala Decoction Powder (麥門冬遠志散), and Cattle Gallstone Formula to Clear the Heart (牛黃淸心元) were found in important ancient literature and Dried Chestnut and Holotrichia Decoction (乾栗蠐螬湯) and Dried Chestnut and Tree of Heaven Root Bark Decoction (乾栗樗根皮湯) are the combination originally set by Lee Jema. Conclusion : Because 70.8% of the prescriptions in 1901PCDT could be found in literature which were pervasive in the period of the Joseon Dynasty (the period of Ming and Qing), it corresponds with Lee Jema’s view that medical men in the Song, Yuan, and Ming Dynasties disclosed half of the prescriptions for Tae-eum person by studying these texts more.

김성원(Kim SungWon),이병욱(Lee ByungWook),김기욱(Kim KiWook) 대한한의학원전학회 2020 대한한의학원전학회지 Vol.33 No.1

Objectives : To compare the herbal ingredients of the prescriptions in ｢Newly Selected Twenty-four Key Formulas applied to Tae-eumin(新定太陰人病應用要藥二十四方)｣ chapter of the Shinchuk edition of the 『Donuisusebowon』 and those from the texts of the Four Great Doctors of the Jin Yuan period. Methods : The herbal ingredients of the 『Donuisusebowon』 and those from 『Huangdisuwen Xuanminglunfang(黃帝素問宣明論方)』, 『Lanshimicang(蘭室秘藏)』, 『Suwenbingji Qiyibaomingji (素問病機氣宜保命集)』, 『Shanghan Biaoben Xinfaleicui(傷寒標本心法類萃)』, 『Piweilun(脾胃論)』, 『Neiwai Shangbianhuolun(內外傷辨惑論)』, 『Shanghanzhige(傷寒直格)』, 『Shanghanxinyao(傷寒心要)』, 『Sanxiaolun(三消論)』 were entered into the database. Next, formulas which included the herbal combination pattern of Tae-eumin formula were determined. Results : Among the 27 Tae-eumin formulas including edited versions, those that showed similar pattern among those in the JinYuan texts were the following 12: Gegenjiejitang(葛根解肌湯)、Reduohanshaotang(熱多寒少湯)、Gegenchengqitang(葛根承氣湯)、Gegentaichengqitang(葛根大承氣湯)、Gegenshaochengqitang(葛根小承氣湯)、Mahuangpobiaotang(麻黃發表湯)、Bufeiyuantang(補肺元湯)、Zaojiaodahuangtang(皂角大黃湯)、Guadisan(瓜蒂散)、Shexiangsan(麝香散)、Shichangpuyuanzhisan(石菖蒲遠志散)、Maimundongyuanzhisan(麥門冬遠志散). Conclusions : Based on the finding that 44.4% of the Shinchuk edition’s Tae-eumin formula patterns could be found in the texts of the Four Masters, Dongmu’s assertion that about half of the Tae-eumin formulas has been clarified by the doctors of the Song, Yuan, Ming eras could be understood as true.

본초 제조 공정의 DB화를 위한 형태소 분석 연구 - 숙지황 제조 공정을 중심으로 -

김태열,김기욱,김병철,이병욱,Kim, Thaeyul,Kim, Kiwook,Kim, Byungchul,Lee, Byungwook 대한예방한의학회 2016 대한예방한의학회지 Vol.20 No.1

Objectives : Treatment method using drugs has already been used in Korean medicine for a long time. Moreover, database has been developed and utilized for more efficient management of the treatments that use drugs. Most of such database related to knowledge on drugs is composed of origin, efficacy, temperament, ingredients and examples of application of the standardized drugs. Communication with knowledge information in other specialized areas is also accomplished by using the efficacies and ingredients with the drugs. In this study, we aimed to make data structure of the terminologies that represent the manufacturing process of herbs. However, in spite of the fact that the manufacturing process of the drugs imparts effect on their efficacies and ingredients, details of the manufacturing processes are quite limited to simple text sentences, thereby resulting in substantially lower level of utilization and difficulties in systematic researches on various factors included in the manufacturing processes in comparison to other knowledge on drugs. Methods : This Study extracted the factors necessary in the development of database by executing morphological analysis of the manufacturing process of herbs. Results : The factors are 'Order', 'Act', 'Raw material', 'Tools', 'Supporting materials', 'Intensity', 'Duration Time', 'Interval', 'Focus', 'Repetition Number', 'Untill'. We were able to tell the difference of the manufacturing process with a simple structured query language and the factors. Conclusions : Morphological analysis of medicinal herbs manufacturing Process contributes to standardization with information of the manufacturing process. And it helps to creates a quality management system through the Database.
