  • Purpose: Traditionally, external bleeding is needed when only an arteriorrhaphy can be performed in cased where a venorrhaphy cannot be done at the initial reconstruction for a zone1 complete amputation. However, this salvage procedure has several iatrogenic complications. Therefore, we did not perform an external bleeding procedure, in cases where external bleeding was not appropriate due to the small size of the stump. Methods: From September 2006 to August 2007, 19 fingertip amputations, among 18 patients, were performed using only arteriorrhaphy without external bleeding; In total 95 fingertip amputations, with venorrhaphy or external bleeding procedures were excluded. The results were reviewed retrospectively to compare survival and complication rates. Results: The survival rate of only arteriorrhaphy without external bleeding is 84.2%. Additional operations for soft tissue problems of total or partial necrosis were performed in 5 cases. Conclusions: We found no difference in the survival and complication rates of only arteriorrhaphy without external bleeding compared to results of only arteriorrhaphy with external bleeding in other articles. Therefore, our results suggest that in some cases with a fingertip amputation, performing arteriorrhaphy only, without external bleeding, might be a better option than external bleeding due to reduced iatrogenic injuries and complications.

  • The Muryangsa temple five-storied stone pagoda (Treasure No. 185) was geographically located in the area of the Baekje Kingdom. The architectural style of the Muryangsa temple five-storied stone pagoda is the pagoda at the early Goryeo Dynasty that was succeeded technique of the Baekje Kingdom and form of the Shilla Kingdom. Because this pagoda is located outside during old time that it received serious petrological and biological weathering in rock blocks and occurred the center subsidence in the upper capstone. This study executed ground stability interpretation in order to know what central subsidence in the upper capstone occurred for soft ground. The ground stability interpretation used seismic survey, electrical resistivity survey and GPR survey by non-destructive method. As the result, the ground appeared in the condition which is good. Specially, high resistance zone appeared from electric resistivity survey which come to seem with ground reinforcement harden. Consequently, central subsidence condition in the upper capstone is not by the instability of ground, and is judged with the thing by the structure instability in rock blocks over the upper capstone. This will be applied basic data with the long-term monitoring or preservation countermeasure of the pagoda.

  • Giant lymph node hyperplasia(Castleman's disease) is a rare disease, which represents a peculiar form of lymph node hyperplasia. Generally, it has been considered as benign and localized disease but recently, revealed malignant transformation in some cases of multicenteric form. It usually occurs on the mediastinum and occasionaly neck, lung, axilla, mesentery, broad ligament, retroperitoneum or soft tissue of extremities. Histopathologically, it is divided into hyaline vascular or plasma cell type and the former is characterized with prominent vascular proliferation and hyalinization in the central portion and tight concenteric layering of lymphocytes at the periphery of the fillicles(mantle zone) and the latter is characterized by a diffuse plasma cell proliferation in the interfollicular area. From the point of view of clinical presentation, it has been divided into solitary form, which presents as a localized mass located most commonly in the mediastinum, and multicenteric form, which occurs multiple location and has systemic manifestation arid transformation into malignancy. Herein we report a case of Giant lymph node hyperplasia occuring in the left spermatic cord in a 58-year old male with brief review of literatures.

  • A 10-year-old female Yorkshire terrier with the clinical signs of nasal swelling, epistaxis and nasal discharge was presented to the Veterinary Teaching Hospital in the Cheju National University. Abnormal nasal mass was detected in physical examination and radiographic findings. After surgical excision, the sample of nasal mass was referred to Pathology Department of Veterinary Medicine. Grossly, the mass was soft, friable, and $2.5{\times}4cm$ cm in size. Histopathologically, the mass was composed of mediumsized non-keratinizing columnar to polyhedral cells arranged in anastomosing ribbon and large nest. It has complex in-folding of thick epithelial layers separated by fibrovascular septa. Tumor cells showed characteristic palisading arrangement of columnar cells, and perpendicularly distributed to the basement membrane. The cells had pale basophilic cytoplasm, oval nucleus and one or more nucleoli, and indistinct cellular border. Many tumor cell emboli were presented in lymphatics. Immunohistochemistry revealed that tumor cells were cytokeratin (CK) 19 and CK clone MNF116 positive and but CK7 and CK high molecular weight negative. Based on the gross, histopathologic, and immunohistochemical findings, the mass was diagnosed as transitional carcinoma in nasal cavity. In our best knowledge, this is the first report of transitional carcinoma originated from transitional zone of canine nasal cavity in Korea.

  • The implicit finite difference program was developed to evaluate the relationship between time and consolidation ratio within the zone of vertical drain effective radius. In the evaluation, the excess pore water pressure was considered to dissipate in two directions, namely, vertical and radial flow direction. To calculate subsoil stress increments in the soil due to multi-step embanking, the foundation soil was assumed to be an isotropic and homogeneous elastic medium and the initial excess pore water pressure was estimated by using Skempton's parameters whose condition is plane strain and elastic phase of pore pressure response within the soft ground. Regarding to the settlement estimation, immediate and primary consolidation settlements were calculated. The secondary or delayed consolidation settlement was not considered. Numerically calculated excess pore water pressure and settlements were similar to the measured data in situ. Thus, this method can be used to predict the time-consolidation ratio of each layer treated by vertical drain method.

  • Purpose: Although lipoma is known as one of the most common soft tissue tumors, calcification in lipoma is very rare in its occurrence. This calcified lipoma has been reported by some as a result of regression of lipoma, but its genesis is not clearly known yet with various opinions being discussed regarding its possible metabolic relation to hypercalcemia or hyperphosphatemia to be considered as a regression phase of lipoma. The authors would like to present this unusual case of calcified lipoma. Methods: A 50-year-old male patient visited our hospital with complaint of an enlarging mass on his right forehead which has been acknowledged for 5 years' period. On physical examination, a mass was observed on his forehead as palpable, non-tender, mobile and firm in its consistency. Ultra sonogram examination revealed a well-demarcated mass (1.92 cm) with central echoic zone at deep layer of forehead. Mass excision and biopsy were performed subsequently. Results: According to the pathological report, the diagnosis confirmed the lipoma consisting of grown-up adipocyte and calcification. Neither growing lipoma nor relapse was observed for postoperative three years' follow-up of the patient. Conclusion: Now that the calcified lipoma was successfully removed and cured by a simple mass excision, authors hereby report the case of calcified lipoma on forehead.

  • Tempormandibular Joint pain and dysfunction is a common and important clinical problem. With the recent advances in imaging technology, radiologists have made major contribution to the understanding of TMJ disease. The MRI has several advantages over the conventional imaging methods. It is possible to obtain surprisingly precise images of internal hard and soft tissues with MRI. It is not invasive without ionizing radiation. The abnormal disk position has been thought as the cause of TMJ internal derangement. But there are few methods to relate disk position to TMJ internal derangement quantatively. The object of our study is to determine the amount of anterior displacement fo articular disk in symptomatic patients related each symptoms. Using the method of Dr. Drace, we studied the 38 joints of 22 persons with susceptable TMJ internal derangement. 1. In determining the anterior displacement of TMJ articular disk, the junction between the posterior band and bilaminar zone was useful. 2. The mean anterior displacement of disk in reduction group and without reduction group were $51.0^{\circ}C$ and $81.1^{\circ}C$ respectively. The difference was significant. 3. In the mean anterior displacement of disk, the pain without clicking group showed $84.8^{\circ}C$ and the clicking and pain group $70.8^{\circ}C$, the clicking group respectively.

  • Upper canine is important because it protects and maintains the stability of the dental arch and also, joins the anterior with the posterior teeth. The incidence of impaction of upper canine is the second most frequent next to the third molar because it takes a long period of time to develop, and has a complicated path of eruption, and erupts lately. After the age of 10, clinical and radioglaphic examination can be used in revealing the possibility of impaction and efforts should be put to reduce the side effects. To prevent impaction, selective extraction of primary canine at the age of 8 to 9 could be considered and prolonged retention of primary canine in oral cavity should be avoided at this time. Once the impaction is iden, the first stage of the treatment is to lcocalize the lesion by radiographic examination and According to the severity, orthodontic traction or autotransplantation should be considered and comprehensive diagnosis and treatment plan of malocclusion should be established. Generally, labial impaction is due to arch length discrepancy and palatal impaction is due to malposition or morphologic pathosis of lateral incisors rather than arch length discrepancy. In surgical procedure, peridontal problems should be considered and the minimum amount of bone and soft tissue should be reduced and direct bonding method of many attachment methods should be recommended. Especially in traction of labially impacted canine, it should be guided to erupt through the keratinized zone and proper forced magnitude should be applied. The importance of periodontal condition should always be in mind following the patient education to mintain the good oral hygiene at each stage of treatment. Properly managed impacted canine can provide function and esthetic by proper diagnosis and treatment if extraction of canine is not indicated.

  • Introduction: Microsurgical replantation of amputated digit have become common procedure in recent years. However replantation of fingertip amputation, Zone I by Yamano classification, is still difficult because digital arteries branch into small arteries and also digital veins are hard to separate from the immobile soft tissue. So, fingertip amputation was covered by volar V-Y flap, composite graft, cross finger flap and groin flap. But patients who have been treated by these methods experience shortening of digit, nail deformity, excessive tenderness and persistent pain. Replantation could solve most of these problems. Material & Methods: In our department, from March 2004 to August 2007, 36 digits in 32 patients with complete amputation at distal to nail base were replanted using a microsurgical technique. Results: The overall survival rate of the replanted finger was 75%. Venous anastomosis was possible in 8 cases and impossible in 28 cases. In latter cases external bleeding technique was applied with medical leech. Conclusion: After replantation, a few patient complained decreased sensibility, nail deformity and cold intolerance. But most of patients were satisfied with the functional and cosmetic appearance of the viable replanted digits. We believe the replantation should be the first choice in fingertip amputation.

  • The grain complex of Saemangeum is created for promoting the foundation of agriculture combined the global competitiveness. However, the masterplan is being also revised with changing of local conditions and social needs. Thus, the dynamic masterplan is needed to consider the change of time for Saemangeum project. The present study was made to set up the dynamic masterplan of Saemangeum grain complex for handling the change such as project progress, local environment, and project conditions flexibly. In this study, the dynamic masterplan for the progressive development of water supply, farmland composition, and introduction facilities is presented to the 6-2 zone in three stages. We believed that the water supply would be possible through the pumping and desalination facilities with the development stages. The farmland composition proceeded for each complex with reclamation, soil preparation, and soft soil processing. And it is planned to carry out crop cultivation from the complex where the construction is completed first. The introduction facilities were analyzed focusing on the silos and forage loading facilities, and the optimal location of them was selected using road and accessibility. The concept of dynamic masterplan may provide the direction for the planning and progress of reclamation project.
