박문성,오주병,진병운,김혜규,박성열,Park, Mun-Seong,O, Ju-Byeong,Jin, Byeong-Un,Kim, Hye-Gyu,Park, Seong-Yeol 한국정보처리학회 1995 정보처리논문지 Vol.2 No.5
차세대 지능망(AIN : Advanced Intelligent Network)과 X.500 디력토리 서비스 사 이의 관계에서 AIN의 SCF/SDF(Service Control Function/Service Data Function) 인터 페이스 요구 사항과 X.500 능력(Capabilities) 간에는 많은 유사성이 존재한다. 또한 X.500의 DUA(Directory User Agent)는 SCF,DSA(Directory System Agent)는 SDF로 매핑 관계가 성립된다. 이러한 유사성과 매핑 관계를 기반으로 AIN에 X.500 디렉토리 시스 템을 SCF/SDF 관계에 DAP(Directiory Access Protocol), SDF-SDF 관계에 DSP(Directory System Protocol)을 적용할 수 있다. 본 논문에서는 CS(Capability Set)-1, CS-3 범위 에서 X.500 DAP/DSP 적용이 가능한 관계를 보이고, AIN의 분산 처리를 위한 AIN SDF Server를 설계했으며, UPT(Universal Personal Telecommunication) 서비스를 AIN SDF Server에 적용할 수 있도록 X.500 스키마를 제안하였다. Advanced Intelligent Network(AIN) and X.500 directory service have similarity in between. X.500 capabilities and the requirements for the Service Control Function(SCF) to Service Data Function(SDF) in AIN. As an interface, SCF can be mapping as a Directory User Agent(DUA) and SDF can be mapping as a Directory System Agent(DSA). Based on the concepts, X.500 directory can be applied to AIN. In this paper we suggest to apply the X.500 DSP to the SDF/SDF interface to perform a distribution function. Also we show that the SCF-SDF/SDF-SDF relationship can be possible under applying X.500 DAP/DSP within the set of Capability Set 1 (CS1),CS2 and CS3. Finally, based on the above contents, we introduce the designed schematic of AIN SDF Server System for a distributed processing in AIN and design the X.500 schema of Universal Personal Telecommunication(UPT) service for supporting AIN SDF Server.

The purpose of this study was to investigate the effects of resorbable, non-resorbable and bovine-derived hydroxyapatite(HA) on the repair of experimental bone defects. Six mongrel dogs, weighing 15kg, were used. Four surgical bone defects sized 1㎤ were created at the iliac bone under general anesthesia. In control group, the defect was filled with blood clot : in resorbable HA group, filled with resorbable HA: in non-resorbable HA group, filled with non-resorbable HA: and in bovine-derived HA group, filled with bovine-derived HA. The animals were sacrificed at 1, 2, 4, 8 and 12 weeks after the graft. Tissue specimens were obtained for radiographic and light microscopic examination. Results obtained were as follows: 1. Macroscopically, neither infection of the graft site nor dislodgement of the grafted material was noted. 2. In the examination of radiographic density, gray level of all of the HA groups was higher than that of the control group. The gray level increased in all groups with time, but the rate of increase was slowered in the non-resorbable HA group. 3. In the resorbable HA group. woven bone was formed from surrounding host bone through osteocondurction at 1 week after the graft. The bone defect was healed with bone trabeculae at 4 weeks and with mature bone at 8 weeks after the graft. 4. In the non-resorbable HA group, healing process was slower than that in the resorbable HA group and unresorbed HA particles were observed at 12 weeks after the graft. 5. In the bovine-derived HA group, bone trabeculae were formed through interconnection of woven bone matrix and the lamellar structure was seen in the 8 weeks after the graft. 6. In all HA groups, new bone formation was more rapid than that in the control group. There were no significant differences in the capability of bone formation among the three HA groups, where new bone was formed by osteoconduction. These results suggest that resorbable, non-resorbable, and bovine-derived hydroxyapatite can be used as bone substitutes to promote new bone formation in the bone defect.

Retrospective study of 89 oral cancer patients from Jan. 1987 to Dec. 1994, who have been treated at the Department of Oral and Maxillofacial Surgery, Chonnam University Hospital, was performed to assess or, if needed, to revise our present treatment protocol. The analysis was focused on the clinical and histopathological findings, treatment methods and their results. The results obtained were as follows: The histologic diagnosis of oral cancer was mostly squamous cell carcinoma followed by malignant melanoma, malignant fibrous histiocytoma. Tie lapse from the recognition of initial symptoms to the first visit was mostly less than 3 months. T4 was the most frequent followed by T3, T2, T1. The situation was the same for the clinical stage. The degree of histopathological differentiation of oral squamous cell carcinoma was in the order of well, moderate, poor differentiated type. T4 was common at maxillary sinus, maxillary and mandibular alveolus and T2 was common at mouth floor. Most cases were treated by combined therapy consisted of presurgical chemotherapy. Surgical resection and postoperative radiation therapy. In 35 cases. Surgical resection was performed. Immediate reconstruction was done in 22 cases and secondary reconstruction was done in 8 cases. The periods between primary surgery and reconstruction were 12.4 months in average. In 26 cases out of 89 cases, recurrence or metastasis was confirmed. The latest follow-up revealed that 33 patients were still alive while 35 were expired due to the malignancy.

Vscularized calvarial bone flaps have been useful tools in the reconstuction of different type of bone defects in craniofacial surgery Vascularized bone transfer are often preferred to nonvascularized bone grafts because nonvascularized bone grafts are less resistant to infection, mot as mechanically strong, and do not survive well in a poorly vascularized bed. Potential advantages of vascularized outer table cavarial bone flap include proximity to the operative feild, membranous origin similar to that of the facial skeleton, maleability which allows for a variety of shapes and sizes, inconspicous donor sit scar. The following are the case reports of two patients who underwent craniofacial reconstruction suing vasularized outer table calvarial bone flap.
