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.

Anterior segmental osteotomy were performed in 8 patients with Angle's II malocclusion or anterior maxillary protrusion. Cupar's method was used for operation. The period of follow up for patients were 15months by average. This study discussed the postoperative complications and soft tissue change after anterior segmental maxillary osteotomy. There are not specific major complications.

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.

We report a case in which a right mandibular incisor was impacted beneath an odontoma in the anterior mandible. An odontoma at the symphyseal region was removed under general anesthesia, and bone was grafted. Tooth #41, which was beneath the lesion, was extracted and transplanted to its original site. It was splinted with resin for 2 weeks and was checked at intervals during that time. After 4 months, it was filled endodontically with calcium hydroxide.
腎細胞癌 細胞核 영상의 등급별 분류를 위한 3차원 텍스쳐 定量化 연구

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.

The purpose of this study is to investigate the dwelling condition of campus village around Gyeongsang National University and suggest the desirable directions of student housing for the mutual development of the university and the community. The study regulates overall situations and problems of the campus village and analyzes the actual dwelling condition of student housing through a field survey and a post-occupancy evaluation. The result of the analysis shows that the internal dwelling condition of student housing does not properly accommodate the student's needs and behavior, compared to its external structure and facilities.

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
