수동변속기 트랜스미션케이스의 피로파괴 분석

임중연 동국대학교 산업기술연구원 1996 산업기술논문집 Vol.7 No.-

본 논문은 로드-로드 스펙트럼 분석기법을 적용하여 자동차 트랜스미션케이스의 피로파괴분석을 다룬 것이다. 수동변속기의 트랜스미션케이스는 다양한 주기적 하중을 받고 있으며 결과적으로 케이스표면에 가끔 균열이 발생되기도 한다. 본 연구에서는 지지방식이 엔지 3점지지 방식에서 트랜스미션 3점지지 방식으로 바뀌면서 발생하는 균열의 원인분석에 관한 것이다. 트랜스미션 3점지지 방식은 내구시험중 드레인플러그 부위에서 균열이 조기발생되었다. 이러한 원인을 정량적으로 분석하기 위하여 1 사이클 내구시험동안 각각의 지지방식에 대하여 누적손상량을 계산할 수 있는 실험 및 컴퓨터를 이용한 분석이 병행되었다. 결과적으로 트랜스미션 3점지지 방식이 엔진 3점지지 방식보다 트랜스미션케이스의 드레인플러그부위에 더 많은 손상을 준다는 것이 판명되었다. This paper is concerned with the fatigue fracture analysis of the automobile transmission case by applying road-load spectrum analysis technique. The manual transmission case receives various cyclic load and sometimes results in crack on the surface of case. Our study investigates the crack occurrence of new model which employes the three-point mounting support on transmission while previous one used three-point mounting support on engine. The crack has been detected near the drain plug for the type of three-point mounting support on transmission during the early stages of endurance test. To find out the cause quantitively, experiment and computational analysis have been carried out to calculate the cumulative damage for both support types during one cycle endurance test. The numerical results show that the type of three-point mounting support on transmission gives larger damages on the surface of transmission case than that of three-point mounting support on engine.

Melandrin의 방향족 유도체 합성에 관한 연구

임중기,이강노,함원훈,이상인 성균관대학교 약학연구소 1992 成均藥硏論文集 Vol.4 No.1

Melandrin, as a possible phytoalexin, which is expected to have the various pharmacological activities; antibacterial, antifungal and antiviral activity, was isolated in 1987 by Woo from Melandrin firmum (Caryophyllaceae). The synthesis of melandrin derivatives has been accomplished by the reaction of 5-hydroxy anthranilic acid ethyl ester with acid chlorides and then by hydrolysis of ethyl ester.

Development of Sediment Assessment Tool for Effective Erosion Control(SATEEC) in Small Small Scale Watershed

임경재,최중대,김기성,사공 명,버나드 엥겔 江原大學校 附設 環境硏究所 2003 環境硏究 Vol.20 No.-

The Revised Universal Soil Loss Equation (RUSLE) has been used in over 100 countries to estimate potential long-term soil erosion from the field. However, the RUSLE estimated soil erosion cannot be used to estimate the sediment delivered to the stream networks. For an effective erosion control, it is necessary to compute sediment delivery ratio (SDR) for watershed and sediment yield at watershed outlet. Thus, the Sediment Assessment Tool for Effective Erosion Control (SATEEC) was developed in this study to compute the sediment yield at any point in the watershed. To compute spatially distributed sediment yield map, the RUSLE was first integrated with the ArcView GIS and three area based sediment delivery ratio methods were incorporated in the SATEEC. The SATEEC was applied to the Bangdong watershed, Chuncheon, Gangwon Province to demonstrate how it can be used to estimate soil loss and sediment yield for a watershed. The sediment yield using USDA SDR method is 8,544 ton/year and 4,949 ton/year with the method by Boyce. Thus, use of watershed specific SDR is highly recommended when comparing the estimated sediment yield with the measured sediment data. The SATEEC was applied with hypothetical cropping scenario and it was found that the SATEEC can be used to assess the impacts of different management on the sediment delivered to the stream networks and to find the sediment source areas for a reach of interest. The SATEEC is an efficient tool to find the best erosion control practices with its easy-to-use interface.

Abstracts-Prostaglandins exhibit diverse pharmacological properties and are now recognized as local hormones that control a multitude of important physiological process. (R)-4-hydroxy-2-cyclope-ntenone is a very useful intermediate to synthesize the prostaglandin derivatives. The optically active cyclopentenone building blocks were synthesized in various ways ; by resoultion of the racemic hydroxy ketone ; by preparation from chiral natural products via resolved synthetic intermediates, by asymmetric synthesis, by microbial or enzymatic techniques, etc. The hydroxy ketone can be produced by preparation from chiral building block via microbial organisms. The key chiral building block is dimethyl-5-hydroxy-4R-hydroxy-2-oxopentane phosphate which can be synthesized the optically active cyclpentenone via Horner Emmon reaction. This paper describes the preparation of the chiral diol compound 2 in detail.

16S rDNA 클론 library 제작 및 핵산염기서열 결정을 통한 교정용 미니임플랜트 주위 열구의 세균 동정

임성훈,김광원,유소영,국중기,장영일 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.4

교정치료 시 고정원으로 사용되는 교정용 미니임플랜트는 가동성 점막인 치조점막 부위에 식립해야 하는 경우가 많은데, 이때 미니임플랜트 주위 연조직의 증식을 동반한 염증이 빈번히 발생한다. 본 연구에서는 치조점막에 식립하여 연조직 증식이 발생된 미니임플랜트 주위의 세균총과 동일 환자의 인접한 건강한 치은 열구의 세균총을 비교하고자 하였다. 이를 위해 7명의 환자를 대상으로 하악 구치부의 치조점막에 식립하여 연조직 증식이 발생한 미니임플랜트 및 이에 연결된 결찰선 주위 열구의 세균막과 미니임플랜트에 인접한, 치은 염증이 없는 제2대구치의 치은열구의 세균막을 멸균된 paper point로 채취한 후, 16S rDNA 클론 library 제작 및 핵산염기서열 분석법을 이용하여 세균을 동정하여 비교하였다. 실험 결과 미니임플랜트 주위 열구로부터 304개의 16S rDNA 클론을 얻었으며, 치은열구로부터 238개의 16S rDNA 클론을 얻었다. 클론의 9.2%에 해당하는 24종의 세균들은 미니임플랜트 주위 열구에서만 검출되었고, 이들은 Haemophilus aphrophilus, Sphingomonas species, Capnocytophaga species, Prevotella melaninogenica, Lachnospiraceae species, Porphyromonas species, Neisseria flava 등이었다. 전체 클론의 80.4%에 해당하는 29종의 세균들은 미니임플랜트 주위 열구 및 건강한 치은 열구 모두에서 검출되었다. 이들 중 특히 미니임플랜트 주위에서 더 많은 클론이 분리된 세균들은 Prevotella species, Atopobium rimae, Veillonella species, Streptococcus intermedius/constellatus, Streptococcus salivarius 등이었다. 향후 연구에서는 본 연구에서 치조점막에 식립한 미니임플랜트 주위에서 검출된 세균들이 염증을 일으키거나 악화시킬 수 있는지를 밝히는 것이 필요하며, 이를 바탕으로 치조점막에 식립한 미니임플랜트 주위의 연조직 염증을 줄일 수 있는 방법을 찾는 것이 바람직하다. Objective: The purpose of this study was to compare the bacterial flora at the peri-implant sulcus of the orthodontic mini-implant placed in the alveolar mucosa with the bacterial flora at the adjacent healthy gingival sulcus. Methods: Two plaque samples from 7 patients were collected by inserting paper points into the sulcus between the mini-implant and ligature wire connected to the mini-implant head and inflamed alveolar mucosa, and from the gingival sulcus of a healthy tooth adjacent to the mini-implant. Results: Using 16S rDNA clone library, the 24 kinds of bacteria including Haemophilus aphrophilus, Sphingomonas species, Capnocytophaga species, Prevotella melaninogenica, Lachnospiraceae species, Porphyromonas species, Neisseria flava were identified only from the sulcus around the mini-implant. These bacteria constituted only 9.2% of total clones, and the bacteria identified from both the sulcus around mini-implants and the gingival sulcus constituted 80.4% of total clones. Of these bacteria, clones of Prevotella species, Atopobium rimae, Veillonella species, Streptococcus intermedius/constellatus, Streptococcus salivarius were more frequently isolated from the peri-implant sulcus. Conclusion: This study suggests that a broad epidemiological study is needed to find causative bacteria which induce inflammation from the peri-implant sulcus.

To reduce the errors, in the microdetermination of carbon and hydrogen by the electrical automatic combustion apparatus, measured the errors due to the positions' of sample in the carbon and hydrogen combustion tube. The samples are used Glucose, Acetanilide, Phenacetin and Diazoamino-benzene. Experimented positions of samples were 3cm, 5cm, 7cm, 8cm and 9cm, from the front edge of the long stationary burner. Every samples determined twice and took the averages of measured carbon and hydrogen's values of each samples. In this experiment, it was found that the most suitable position of sample in the carbon and hydrogen combustion tube is 8cm from the long stationary burner.
