협측 공간 병변: CT와MR영상소견에 기초한 새로운 분류법
한문희,한문희,제환준,최혁재,김영준,김인원,장기현,Han, Mun-Hui,Han, Mun-Hui,Je, Hwan-Jun,Choe, Hyeok-Jae,Kim, Yeong-Jun,Kim, In-Won,Jang, Gi-Hyeon 대한영상의학회 2004 대한영상의학회지 Vol.50 No.2
목적: 협측 공간 병변의 CT와 MR 영상소견에 기초한 새로운 분류법을 소개하고, 협측 공간 병변의 감별진단에 지침을 제공하고자 한다. 대상과 방법: 조직병리학적 또는 임상적으로 진단된 62예의 협측 공간 병변을 대상으로 하였다. 모든 병변은 그 형태학적 모양과 주변 공간으로의 침범에 따라 다음과 같이 3가지 형으로 분류하였다. 협측 공간에 국한되어 있고 명확한 경계를 가진 경우를 1형, 협측 공간에 국한되어 있고 불명확한 경계를 가진 경우를 2형, 그리고 여러 공간을 동시에 침범한 경우를 3형으로 하였다. 결과: 다형성선종, carcinoma ex pleomorphic adenoma, B-cell 임파선암, 세엽세포암종, 횡문근육종, 사구종양, 사기질모세포종은 1형으로 분류되었고, 악성종양과 양성종양의 감별은 불가능하였다. 농양, 감염이 동반된 유피낭종, Kimura 병, 선낭종암은 2형으로 분류되었다. T-cell 임파선암, 신경섬유종, 혈관기형, 두경부 염증, 이물육아종은 3형으로 분류되었고, 각각은 다른 영상 소견을 보였다. 결론: CT와 MR 영상소견에 기초한 이 새로운 분류법은 협측 공간 병변의 감별진단에 지침이 될 수 있을 것으로 생각한다. Purpose: To present a new classification based on the CT and MR imaging findings of buccal space lesions, and to propose guidelines for their radiologic differentiation. Materials and Methods: Sixty-two histopathologically confirmed or clinically diagnosed buccal space lesions were classified on the basis of their morphologic appearance and extension to adjacent space as either (1) a mass with a distinct margin, confined to the buccal space; (2) a mass with surrounding infiltration, confined to the buccal space; or (3) a multi-space occupying mass. Results: Type 1 included pleomorphic adenoma, ex-pleomorphic adenoma, carcinoma, B-cell lymphoma, acinic cell carcinoma, rhabdomyosarcoma, glomus tumor and ameloblastoma, and differentiation between malignant and benign neoplasms was not possible. Type 2 included adenoid cystic carcinoma, abscess, complicated dermoid cyst, and Kimura disease. T-cell lymphoma, neurofibroma, vascular malformation, inflammation, and foreign body granuloma pertained to type 3, and each type-3 entity showed different imaging characteristics. Conclusion: This new classification based on CT and MR imaging characteristics may provide useful guidelines for predicting the differential diagnosis of buccal space lesions.

한문희 서울대학교 2013 외국어교육연구 Vol.16 No.-
In general the pronunciation of French is not easy to learn, especially for beginners. The students of secondary education have much difficulty pronouncing French words which often creates fear, deters students and even makes them give up to practice French language. Our purpose is to present a phonetic system for the French novice not only to encourage communication in language but also which helps to learn easily and with interest. So we examined what is the norm for the pronunciation of French and analyzed the text books used in schools and the teaching materials for “FLE” in France. As a result, we found that seven oral and three nasal vowels are considered sufficient for communication. For the consonants there are almost no variations according to the standard or standardized French pronunciation.

Pseudomonas syringas 빙핵활성 단백질 유전자의 크로닝
한문희,홍주봉,이혜주,우진경,김정하,함경수 생화학분자생물학회 1993 BMB Reports Vol.17 No.3
A gene codes for a protein with ice-nucleation activity has been cloned from a plant pathogenic strain of Pseudomonas syringae in Korea. Once the gene has been introduced into E. coli, the transformed E. coli showed strong ice-nucleating activities; while the freezing temperatures of the 10 mM phosphate buffer, pH 7.0, with E. coli were from -10℃ to -14℃, E. coli once transformed with pGINP-1 raised the freezing temperature to about -5℃. Restriction enzyme mapping of pGINP-1 showed two Pvu II and two Sal I sites in 4.7 kbp DNA fragment flanked with Bgl II and EcoRI restriction enzyme sites.

공침법에 의한 Cordierite분말의 합성 및 소결에 관한 연구
한문희,박금철 한국세라믹학회 1990 한국세라믹학회지 Vol.27 No.7
The cordierite powders were prepared from Mg(NO3)2.6H2O, Al(NO3)3.9H2O and colloidal silica by the coprecippitation method, and the sintering behavior of the powders were investigated. Two different methods were applied for producing the precursor powders. The one was to added the aqueous solution of Mg(NO3)2.6H2O and Al(NO3)3.9H2O to NH4OH to adjust pH at 10 where the colloidal silica of pH 10 was added. The other wa to add the aqueous solution of Mg(NO3)2.6H2O and Al(NO3)3.9H2O to the colloidal silica with NH4OH to control the final mixture to be at pH 10. It was confirmed that more homogeneous powders were obtained from the latter method. The firing linear shrinkage of the powder compacts fabricated from the calcined powder between 90$0^{\circ}C$ and 110$0^{\circ}C$ was found to be larger as the calcination temperature was low. But all of them stopped shrinking around 120$0^{\circ}C$. The powder compacts, fabricated using the calcined powders at 90$0^{\circ}C$ and 95$0^{\circ}C$ for 2hours and sintered at 142$0^{\circ}C$ for 2hours, showed relative density of 93-96%, 3-point bending strength of 81-83MPa, KIC of 1.9-2.4 MPam1/2 and thermal expansion coefficient of 0.213-0.732$\times$10-6$^{\circ}C$.
