Background : In recent years gonorrhoea has been panendemic and remains one of the most common Sexually Transmitted Diseases in the world, especially in developing countries. Objective & Method : For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria Gonorrhoeae(PPNG), Ive have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1994, 168 strains of N. gonorrhoeae were isolated, among which 109 (64,9% ) were PPNG. Conclustion : Our results suggests that the prevalence of PPNG in Seoul is still increasing.

Penetrating morphologies at the growth front of abnormally-growing Goss grains in Fe–3%Si steel was examined in view ofthe possibility that they are the two-dimensional section of the solid-state wetting (SSW) along the triple junction line. Toobtain the statistically meaningful data, 102 penetrated grain and 204 penetrating abnormally-growing Goss grain morphologieswere examined. The misorientation angles of penetrating and penetrated grains were measured by electron backscattereddiffraction. Among the 102 examined penetrated grain boundaries, none has low misorientation angles less than 15°,whereas 17.2% of the 204 penetrating grain boundaries have low misorientation angles, and 23.5% of them have coincidencesite lattice boundaries. Besides, boundary energies of penetrating Goss grains, which were estimated from misorientationangles of the three grains in the penetrating morphology, satisfied the energetic condition for SSW along the triple junctionline. These results imply that the abnormal grain growth of Goss grains in Fe–3%Si steel occurs by the mechanism of subboundaryenhanced SSW.

We described three cases of immediate reimplantation of a frozen-thawed autogenous mandible composed of a mixture of iliac bone, marrow, and particulate hydroxyapatite in tumors of the mandible. Acceptable outcomes were obtained in three patients who underwent immediate autogenous mandibular graft reconstruction. The conditions leading to successful outcome of the procedure are also discussed. Reimplantation of frozen autogenous lesioned mandible was performed in three patients with mandibular tumors. Two reimplanted grafts survived without complications following surgery. One case had postoperative infection that resolved with appropriate antibiotic treatment. There were no recurrences of the primary lesions. Satisfactory facial contour after surgery was achieved. These results are most promising, and we believe that, with further refinement, this technique will offer a new and acceptable modality for facial reconstruction in patients with cancer.

그리드 포털의 기능 분류에 따른 조사 연구

김태식,구흥서 청주대학교 산업과학연구소 2005 産業科學硏究 Vol.22 No.3

Grid computing enables the virtualization of distributed computing and data resources such as processing, network bandwidth and storage capacity to create a single system image, granting users and applications seamless access to vast IT capabilities. As many researchers have been interested in Grid Technology, they have also focused their attention on PSE where users use Grid easily. Grid Portal, one of PSEs, provides users with web interface so that they will easily run their jobs using Grid. Many grid portals are currently being serviced. We classified the existing grid portals into Grid Information Portals and Grid Application Portals according to functional distinctions. We then studied and surveyed representative grid portals that belong to GIP and GAP

기계적 삭제방법을 이용한 치면열구전색제의 열구 침투도 및 미세누출

김지연,이제호,박기태,김성오,최병재,손흥규 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.1

교합면 치아우식 예방을 위한 치면열구전색제 도포시 열구내 유기물, 치태, 법랑질 잔사 등을 제거하여 전색제의 유지율을 증가시키고자 기계적 삭제 방법이 소개되었다. 기계적 삭제방법을 사용할 경우 산부식 방법만을 사용하였을 때와 비교하여 치면열구전색제의 열구 침투도 및 미세누출정도의 차이는 임상적인 측면에서 중요하다. 따라서 이 연구에서는 기계적 삭제방법(소와열구 삭제 후 산부식)과 산부식 방법을 시행한 후, 각각 unfilled sealant와 filled sealant를 처치하고 이들 치면열구전색제의 열구 침투도와 미세누출 정도를 측정하였다. 교정치료를 목적으로 발거된 사람의 소구치 60개를 실험재료로 사용하였으며 그중 30개는 산부식 처리하고 나머지 30개는 소와열구의 기계적 삭제와 산부식 처리를 시행한 후 각각의 방법에서 15개는 unfilled sealant로 나머지 15개는 filled sealant로 수복하였다. Thermocycling(5℃와 55℃ 1200회)을 시행하고 5% methylene blue 용액에 24시간 보관하였다가 각각의 치아를 근심소와와 원심소와에서 협설 방향으로 절단하여 120개의 절단면을 얻었다. 각 절단면을 Measurescope으로 관찰한 결과, 기계적 삭제 방법은 산부식만을 시행한 경우에 비하여 unfilled sealant와 filled sealant 모두 열구 침투도를 증가시켰다(P<0.05). 기계적 삭제 방법을 사용한 경우 산부식 방법만을 사용하고 unfilled sealant로 수복한 경우에 비하여 미세누출이 적었고(P<0.05), 산부식 방법만을 사용하고 filled sealant로 수복한 경우와는 미세누출에 차이가 없었다. Unfilled sealant와 filled sealant는 기계적 삭제 방법을 사용한 경우와 산부식 방법만을 사용한 경우 모두 열구 침투도나 미세누출에 있어서 유의한 차이가 없었다. 이상의 결과로 보아 치면열구전색제 도포 시 열구 침투도가 우수하고 미세누출이 적은 기계적 삭제 방법과 물리적 성질이 우수한 filled sealant의 사용이 바람직하다고 생각된다. 그러나 미세누출에 있어 교합력을 고려한 실험이나 장기간의 임상실험이 필요할 것이다. Mechanical preparation has been introduced to provide the sealant retention. The objective of this study was to compare the fissure penetration and the microleakage of pit and fissure sealant using mechanical preparation(mechanical preparation + acid etching) and acid etching only. An additional objective of this study was to compare the fissure penetration and the microleakage of unfilled and filled sealant in both methods. Sixty human premolars extracted for orthodontic purpose were selected. Thirty teeth were acid etched alone and remaining thirty teeth were prepared with a ¼ round bur and then acid etched. One-half of teeth in each surface treatment method were sealed with unfilled sealant and the other half were sealed with filled sealant. All of the teeth were thermocycled for 1200 cycles at 5℃ and 55℃ and immersed in 5% methylene blue for 24 hours. Each tooth was sectioned bucco-lingually at mesial pit and distal pit and examined under a Measurescope. In the case of mechanical preparation, fissure penetration of sealant was significantly increased compared with the case of acid etching only(P<0.05). The filled and unfilled sealant using mechanical preparation showed significantly decreased microleakage when compared with the unfilled sealant using acid etching only(P<0.05). No differences were found in fissure penetration and microleakage between unfilled and filled sealant in both methods. Taken together, the results of this study suggest that mechanical preparation and filled sealant are recommended when placing pit and fissure sealant. However, further clinical studies should be performed in regard to microleakage.

Saccharomyces cerevisiae Y-139에서의 hexaconazole의 작용 기작

김흥태 忠北大學校 農業科學硏究所 2002 農業科學硏究 Vol.19 No.-

Saccharomyces cerevisiae 6-3, resistant to hexaconazole, was selected from S. cerevisiae Y-139, sensitive to the fungicide, irradiated with UV light for 32 min EC_50 value of 6-3 showed at 345 58㎍/㎖, while that of Y-139 was 0.21 ㎍/㎖. In YEPD media, the growth rate of Y-139 was higher than that of 6-3 After incubation for 12 hrs, however, the growth of 6-3 in YEPD media amending 1㎍/㎖ of hexaconazole was faster than Y-139 The application of hexaconazole to Y-139 caused the decrease of composition ratio of ergosterol in the cell and the accumulation of irregular sterols such as 14α-methyl-ergosta-8,24(28)-dienol, lanosterol, and 24-methylenedihydrolanosterol The accumulation of irregular sterols was began 2 hrs after application of the fungicide to incubation media of Y-139 Resistance of 6-3 to hexaconazole induced the increase of resistance to nystatin, antifungal agent With these results, it suggests that the action mechanism of hexaconazole in S cerevisiae Y-139 was the inhibition of 14α-demethylase, and that 6-3 happened to be resistant to hexaconazole by the biosvnthesis of another sterol

김태윤,최현주,최흥국 仁濟大學校 2006 仁濟論叢 Vol.21 No.1

세포 영상 분석에 널리 사용되는 형태학적이나 위상학적인 정보뿐만 아니라 세포핵과 염색질의 텍스쳐 특정값들은 병리 진단이나 예후 추정을 위한 중요한 정보들을 담고 있다. 이에 따라, 본 논문은 디지털 세포측정학을 기반으로 신장 세포암 (RCC:Renal Cell Carcinoma)의 컨포컬 레이져 스캐닝 현미경 영상에 적용할 수 있는 등급별 분류 시스템 개발을 위한 3차원 텍스쳐 특성값에 대한 연구를 목적으로 한다. 본 연구를 위해 실제 세포핵 데이터로부터 3D GLCM과 3D GLRLM을 정의하고 값을 추출하여 정량적인 분석을 수행하였다. 또한 통계학적인 처리를 통해 6개의 분류 모델을 생성하고 비교하여 그 유효성을 평가하였다. 본 연구의 결과를 통해 현재 널리 이용되고 있는 2차원 기반 영상 분석의 한계를 극복하고 보다 정확한 진단과 예후 추정으로 높은 임상 활용도를 제공할 수 있는 3차원 기반의 새로운 등급 시스템 개발의 기반을 마련하고자 한다. The objective of the this thesis is to study of three-dimensional textural features applied to laser scanning confocal microscopy based on the Digital Image Cytometry. For this study, first, we performed a visualization of cell nuclei using three-dimensional surface rendering and labelling. Then, we also extracted texture feature values from three-dimensional co-occurrence matrices and run-length matrices and performed quantitative analysis using statistics. Finally we tested new classification model based on three-dimensional texture features and performed the comparative study using 5 classification model for validation. Through the result of this study, we could be develop a new grading system of the renal cell carcinoma which have higher clinical usability.
