There are two approach methods in reduction of mandibular fracture, one is external approach and the other is intraoral approach. Most surgeon have been used external approach but intraoral approach gives many benefits. The authors performed interosseous fixation of various sites of 10 cases of mandibular fracture through intraoral approach and concluded that advantages of this method are; 1. no external scar 2. complete reduction (alignment) 3. decreased rate of malunion, maloclusion 4. fewer possibility of facial nerve injury 5. shorter operation time.

Rail noise and vibration is one of the major problem for the residents living nearby railway tracks. The rail noise may inflict a considerable damage to physiological, spiritual, mental and discomfort to neighboring peoples. Therefore, residents living nearby railway were appeal many troubles. Nevertheless, in our country, adequate guidelines for the rail noise are not yet established because of the lack of basic data and insufficient research works. In this point, this study attempts to surveys the influence of rail noise in urban area using questionnaire. This study also present a basic data in establishing effective plans for rail noise in the future.

목적 : 기능성 소화불량증은 소화, 흡수등 장관의 기능적인 이상과 관련되어 있을 것으로 생각되며 복합소화효소제(Winstal®)를 투여하여 그 임상효과를 평가하고자 본 연구를 실시하였다. 대상 및 방법 : 1994년 3월 부터 6월까지 경북대학교병원 내과를 방문한 기능성 소화불량증을 호소하는 환자 20명을 대상으로 Winstal®을 1회 1정씩, 1일 3회 식후 30분내에 경구로 2주간 투여하였다. 결과 : 소화불량증의 증상은 복부불쾌감, 복부팽만감, 식욕부진 및 오심, 복부동통, 공기연하증, 고창 및 구토순이었으며, 증상의 개선은 복부불쾌감이 76.4%(13/17)로 가장 높았으며, 그 다음으로 복부팽만감 및 공기연하증이 66.5%(10/15, 6/9)이었고, 오심 61.5%(8/13), 식욕부진 53.8%(7/13), 복부동통 41.6%(5/12), 고창 37.5%(3/8)이었다. 각 환자별 종합적인 증상의 개선도는 현저한 개선이 2예(10%), 중등도 개선이 3예(15%), 약간개선이 11예(55%), 불변이 4예(20%)이었으며 종합적인 유효율은 80%(16/20)이었다. 부작용은 한 예에서도 관찰되지 않았다. 결론 : 본 제제는 기능성 소화불량증 환자의 증상개선에 추천할 만한 유효한 약제로 생각된다. Dyspepsia is a common symptom in gastroenterologic practice and trigger for numerous consultations with physician. The treatment of chronic functional dyspesia is unsatisfactory. This study was performed to evaluate the efficacy of the digestive compound (Winstal®) on 20 functional dyspepsia patients. On open trial, all patients were given 6 tablets daily for 2 weeks and we evaluated the efficacy of this preparation according to the degree of the improvement. The improvement of symptoms was 76.4%(13/17) in abdominal discomfort, 66.5%(10/15, 6/9) in abdominal distension and aerophagia, 61.5%(8/13) in nausea, 53.8%(7/13) in abdominal pain, and 37.5% (5/12) in flatulence, respectively. Overall effectiveness of subjective symptoms was 80% (16/20) and there were no untoward effects of the preparations during this study. As a result, We think that this preparation is an effective one to relieve symptoms of functional dyspepsia.

It is imperative to find environment-friendly coatings as an alternative to the currently used hexavalent chromate conversion coatings for the purpose of improving the anti-corrosion properties of aluminum alloys. Hence, in this study, the corrosion properties of a trivalent chromate conversion coating solution are analyzed and measured. Because of the presence of multiple components in trivalent chromate conversion coating solutions, it is difficult to control plating, attributed to their mutual organic relationship. It is of significance to determine the concentrations of the components present in these coatings; hence, qualitative and quantitative analysis is required. The coating solution contained not only an environment-friendly component chromium(III), but also zirconium, fluorine, sulfur, and potassium, in the coating film. These metals are confirmed to produce a film with improved corrosion resistance to form a thin layer. The excellent corrosion resistance for the trivalent chromate solution is attributed to various inorganic and organic additives.

Background : Cynanchum wilfordii and Cynanchum auriculatum belong to the Asclepiadaceae family and appear morphologically similar. In order to discriminate them, it is needed to find the presence of sap and the leaf shapes: C. auriculatum has a blade ovate leaf comparing to C. wilfordii. However, in the herbal medicine market, they have been handled as cut and dried roots. Due to their similar morphology, it is limited to distinguish the roots of C. wilfordii and C. auriculatum. Recently in Korea, it has been a critical issue to misuse these two roots in the herbal market and food industry. Thus, it is required to establish a robust tool for the discrimination and quality control of them. Methods and Results : To separation and characterization of flavor compounds, C. wilfordii and C. auriculatum samples were analyzed by head space solid phase micro extraction (HSS) fiber coupled with gas chromatography-mass spectrometry using Rtx-5MS (30 m x 0.25 mm x 0.25 μm) column. As a result, We have identified compounds of a few hundred in aliphatic aldehydes and aliphatic alcohols, alkenes and acids, aromatic compounds, aromatic compounds containing nitrogen & sulfur, etc,. In particular, The aliphatic and aromatic compounds had been clearly separated on the second dimensional direction by using two-dimensional GC. Conclusion : The volatile flavor compounds of C. wilfordii and C. auriculatum could easily analyzed without pre-treatment with improved resolution and sensitivity using HSS-GCxGC-TOFMS. We have identified compounds of a few hundred in C. wilfordii and C. auriculatum sample. And It was more accurately qualitative confirmed with separation of GCxGC and TSD. We have confirmed the PCA and PLS-DA Plot that was classified depending on C. wilfordii and C. auriculatum through multivariate statistical analysis of the identified flavor compounds.
