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.

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.

The effect of reducing flood magnitudes, flood stages, and flood damage by upstream reservoir regulation are investigated in this study. The analytical procedures which has been established newly, are treated through this study for 7 index stations and same numbr of reaches. The method of this study could be expressed briefly as following procedures. Using stage-frequency relations and the potential damage survey data, damage-frequency relations are established, and from this, average annual flood damages computed. By holding out portions of the floods with various amounts of flood control storage in 6 reservoirs in the basin, routing were made to establish modified stage-frequency relations. From damage frequency relation, average annual damages are computed with and without condition of each control volume. The study result are concluded as follows; (1) The relationtship of corresponding water level between nearby stations are useful tools to adjust error of the data due to observation error and change of the gaging location. (2) The number of records about 10 years could not be applied for the statistical methods of flood frequency analysis. (3) The regional skew factors are recommended to apply flood frequency study by the log-Pearson Type III method. (4) The effect of damage reductions are greatly affectedin accordance with the routed flood. Therefore application of the Typical Tributary Contribution Flood are reasonable for this type of study. (5) In the North Han, effect of damage reduction due to the lacation of control point are gradually increased from upstream to downward until the confluence of North and South Han. (6) In the South Han, control effect are increased from Chungju to Yeoju where the maximum effect are analyzed and then decrease gradually until the confluence. (7) Better hydrologic and topographic combinations for the flood control are existed in South Han to compare with North Han in this study results.

A combined process, extrusion of bimetal wire and then drawing of the bundle of those wires, is introduced to manufacture the nano-class filament wires. This new process is devised to significantly reduce the amount of work compared to the current way of manufacturing the nano-class filament wires, which uses drawing processes as many as approximately one hundred twenty times. Each filament wire is composed of two metals, outer copper ring and inner aluminum wire. As a beginning to examine the possibility of the proposed process with a bimetal wire, the first extrusion of copper-clad aluminum wire is carefully simulated. Several process parameters such as die angle, extrusion ratio and thickness ratio of clad materials are chosen to examine the deformation characteristics as well as damage evolution during extrusion.

감염성 심내막염은 화상 후에 발생할 수 있는 치명적인 합병증이다. 임상 증상은 일반적으로 없는 경우가 대부분이고 지속되는 발열과 양성 혈액 배양 검사가 유일하다. 감염의 다른 확실한 원인 없이 발열과 양성 혈액 배양 검사가 있을 때는 감염성 심내막염을 강력하게 의심해야 하며 심장 초음파로 진단 가능하다. 감염성 심내막염은 사망률은 높지만 초기에 진단하면 항생제 정주를 지속하는 것으로 치료할 수 있다. 저자들은 화상환자에서 발생한 수술적 처치를 필요로 하는 감염성 심내막염 2예를 경험하였기에 보고하는 바이다. Infective endocarditis is a rare but fatal complication following burn injury. The clinical presentation is silent, but with persistent fever and positive blood culture. The manipulation of clinical care as well as the burn wound itself and immunosuppression caused by extensive bums puts the burn patients at risk of bacteremia. Staphylococcus aureus and Gram-negative bacilli are most common pathogens of infective endocarditis following burns. We report herein two cases of infective endocarditis in the burn patients who requires surgical intervention. The first case was caused by Pseudomonas aeruginosa with complication of multifocal pneumonia, and the second case by coagulase-negative stapylococcus with cerebral hemorrhage.

Purpose : To evaluate survival rate, treatment failure pattern and complication of endometrial carcinoma patients treated with radiation therapy Materials and Methods : From November 1989 through March 1995, twenty two patients with endometrial carcinoma were treated with radiation therapy at Chungnam National University Hospital. According to the 1988 FIGO staging system, four patients had stage I A disease, 6 stage I B, 4 stage I C, 1 stage Ⅱ A, 6 stage Ⅲ A, and 1 stage Ⅲ B. Radiation therapy was given preoperatively to 2 patients, postoperatively to 19 patients, and curatively to one patient considered to be inoperable due to valvular heart disease. Twelve patients were treated with external radiation therapy alone by conventional technique (180-200 cGy/fraction), and 6 patients with external radiotherapy plus high dose rate intracavitary radiotherapy (HDR ICR), and 4 patients with HDR ICR alone. Results : All patients were followed up for 9 to 71 months (median 21 months). The overall 5 year survival rate of all patients was 68.9%. The 5 year survival rates of stage I , Ⅱ , and Ⅲ were 87.5%, 100%, and 41.6%, respectively. Relapse rate was 9.1% (2/22), and treatment failure occurred as a distant metastasis only without local failure. Early mild complication rate was 31.8% (7/22), and late complication rate 9.1% (2/22), including one radiation colitis and one vulvar ulcer. Conclusion : Adjuvant pelvic radiation thereapy is an effective local treatment modality to prevent local relapse in patients with endometrial carcinoma not accompanying severe late complications.
