Purpose : We have evaluated the outcome of the operative treatment of PCL rupture using the achilles tendon allograft. Materials and Methods : A retrospective study was completed for 30-PCL reconstruction cases, using the achilles tendon allograft from september 1996 to march 1998. There was an average follow up of 24 months, with range of 12 to 50 months. Results : The active range of motion was improved postoperatively. The Lysholm Knee Score was improved from a mean of 54 points preoperatively to 87 points postoerative 18 months. The "Cybex 340 isometric test" revealed satisfactory results compared with autograft. Conclusions : Use of allograft for recostruction of the PCL is an attractive option because it precludes the harvesting of autogenous tissue in a knee that is already at risk for patellofemoral and tibiofemoral osteoarthrosis.

Tooth movement facilitated by corticotomy and distraction osteogenesis, new paradigm in orthodontics, was discussed. Intrusive tooth movement of anterior or posterior teeth was thought to be difficult or impossible. In this study, a part of cortical bone, which was a sort of resistance to tooth movement in alveolar bone, was removed. On the other hand, active bone deposition was made possible in the tension side. That was the main concept of tooth movement facilitated by corticotomy and distraction osteogenesis. Teeth moved at such a speedy tate as we could not imagine in conventional tooth movement, which lead to the reduction of total treatment Period. And intrusive movement was Possible without a side effect, lot example, root resorption or the periodontal breakdown. Those were the superior aspects to the conventional orthodontics.

Tracheoinnominate artery fistula is a rare but a catastrophic complication after tacheostomy or tracheal reconstruction. We experienced one case of tracheoinnominate artery fistula after tracheal reconstruction. The patient was a 11 year old girl with cerebral arteriovenous malformation who maintained tracheostomy for 6 months before undergoing tracheal reconstruction. She complained of dyspnea and paroxysmal cough 5 months after tracheostomy and was diagnosed as tracheal stenosis. We performed 4cm of tracheal resection and end to end anastomosis. Three days after tracheal reconstruction, massive bleeding occurred through the intubation tube. She underwent emergency reoperation of repair the innominate artery with 5-0 Prolene and re-reconstruction of trachea. The patient died of bleeding 3 days after the reoperation.

The first human meniscal allograft transplantations (MATs) were performed 30 years ago. In the early era, candidates were limited to patients who have favorable joint conditions. MAT is currently indicated for patients with post-meniscectomy symptoms, such as compartmental pain or effusion after a subtotal or total meniscectomy. The current indication for MAT is being expanded to other patients who were not indicated previously. The present article reviews how the indications of MAT have changed over the years.

After limb salvage operation becomes popular, reconstruction method of epi-metaphyseal osteosarcoma is relatively standardized though it may be operator's matter of preference. Most limb salvage techniques presently used are prosthesis reconstruction and osteoarticular allograft. In the case of prosthesis, it is very stable and shows good postoperative functional score, however, finally, it has a weak point of requirement for removal procedure due to failure. In the long run, allograft reconstruction has a good merit. But, it has a weak point of difficulties in securing the demanded size and shape. Allograft reconstruction should be performed only in the case of safe margin and established indication. In limb salvage operation, intercalary reconstruction is useful method in diaphyseal osteosarcoma, however, in metaphyseal osteosarcoma, the indication is not confirmed. We treated 17 year old osteosarcoma patient with localized in the tibial medial condyle with proximal medial condylectomy and pasteurized bone reconstruction in the conviction of safe surgical margin. We report this case because we guess if this procedure may be applied to premature patients, despite failure hemiarthroplasty can be tried successfully.

Purpose: We compared the time how much time spent until the bone unions, when we grafted fresh frozen allograft during therapy of benign bone tumor depends on the degrees of bony unions. Materials and Methods: This study selected 29 cases, in which a curettage on the benign bone tumors was conducted and a fresh frozen allograft was transplanted. The area of the focus, the new bone formation, the recurrence of the focus and complications in the plain radiographs were observed. Results: The average time when we could find out bony unions in the radiographs is eleven weeks. The time when we could observe the unions in the radiographs are 11.4 weeks in allograft group, 10.7 weeks in allograft and autograft groups and 13.6 weeks in allograft and bone substitute. On radiologic findings, the average lesion size is 40 cm3. The time when we could find bony unions are 9.3 weeks in less than 40 $cm^3$ and 12.9 weeks in more than 40 $cm^3$. We could observe recurrences in two cases. Conclusion: The authors could get the similar results between fresh frozen allograft, allograft and autograft after curettage of benign bone tumor. We can think the ideal method which is the transplantation of autograft, but if we can’t get autograft enough, the best way which heal the defects is the transplantation of fresh frozen allograft.

Purpose : This study was aimed to calculate effective dose from cone beam CT and compare effective dose from periapical and panoramic radiography for mesiodens. Materials and Methods : Upper anteiror periapical, panoramic radiography and cone-beam CT were taken for diagnosis of mesiodens. The effective dose were calculated by using an anthropomorphic phantom loaded with thermoluminescent dosimeters at the 23 sites related to sensitive organs. Results : The highest absorbed doses were received by the mandibular body, parotid gland and cheek from periapical, panoramic and cone-beam CT, respectively. The effective doses for periapical, panoramic radiography and cone-beam CT measured 2, 18 and 48 ${\mu}Sv$. Conclusion : Cone-beam CT, although providing additional diagnostic benefits, exposes patients to higher levels of radiation than conventional periapical and panoramic radiography.

우리 전통술산업의 육성은 원료농산물의 소비증대와 수입주류의 대체, 전통문화의 복원 등 다양한 의미를 가지고 있다. 즉 쌀과 잡곡, 과일, 약초 등 우리 농산물로 빛은 민속주의 재현을 통해 개방여파로 인해 남아도는 우리 농산물의 소비증대와 국민들의 건강 증진, 전통문화의 계승발전에도 기여할 수 있기 때문에 산업적 활성화의 필요성이 크다. 특히 술은 지역축제나 관광, 예술 등과 결합한 고부가가치 문화상품이 될 수 있는 만큼 그린투어리즘(green tourism)이나 농촌문화관광을 풍요롭게 하는 중요한 컨텐츠가 될 수 있을 것으로 기대된다. 우리술산업의 활성화를 위한 정책과제로는 다음을 제시할 수 있다. (1) 우리술의 맛과 향, 숙취제거 등 품질을 개선하되 특히, 젊은층과 서민들의 기호에 맞으면서도 건강기능성을 가미한 다양한 제품의 개발과 포장 및 디자인의 개선이 필요하며 이를 위해 전문연구기관을 설립하거나 한국식품개발연구원을 통한 연구개 발과 교육 훈련이 선행되어야 한다. (2) 우리술의 품질관리와 차별적 유통을 위한 브랜드화가 필요한데 이는 지방자치단체와 관련업체에서 지역에서 생산되는 술에 대해 원료나 제조방법, 생산지역 등 품질기준과 표기방법을 제도화하고, 이를 소비자들에게 알리는 방법을 강구해야 한다 (3) 시음회나 품평회, 우리술페스티벌 등 다양한 이벤트행사를 통해 우리술에 대한 부정적 이미지를 개선하고 소비를 촉진하기 위해서는 적극적인 홍보와 판매촉진이 필요하다. (4) 우리 전통술의 품질향상과 가격인하를 위해 시설현대화와 기술개발, 포장 및 디자인개선, 원료구입, 홍보 및 판매촉진 등에 소요되는 자금을 지원하고 주세 차등화 등 조세감면과 경영컨설팅 등의 지원이 필요하다. (5) 현재 국회에 계류 중인 [전통술산업육성 및 지원법(안)]를 통과시켜 제도를 정비하고, 여러 부처에 흩어져 방치되고 있는 농민주 및 민속주 관련 행정체계를 정비해야 한다.

1) 병원에 입원하는 환자들 중 상당수에서 어느정도의 여양실조가 있는 것으로 보고되므로 수술하기 위해 입원하는 환자에서 영양과 관계있는 측면에서 병력청취 및 이학적 검사상 약 6개월간 평소체중의 $10\%$ 이상 감소, 혈장단백(알부민,트란스페린) 저차, 총임파 구수감소 등이 있으면 철저한 영양평가를 시행하여 중등도 이상의 위험군에서는 술 전 약 $7\∼10$일간 영양지원을 하는 것이 약 $10\%$의 술 후 합병증을 줄이는 것으로 보고되나 이는 수술의 스트레스 정도, 술 후 영양섭취 지연의 기간 및 정도 및 수술의 응급여부에 의해 결정한다. 2) 영양지원이 결정되면 그 경로는 경장이 좋으며 그것이 안될 때 정맥영양을 시행한다. 3) 술 전 영양지원을 받지않은 중등도 이상의 영양실조 환자에서 술 후 조기 영양지원에 대한 연구에서는 TPNrns에서 대조군보다 오히려 약 $10\%$의 합병증 발생률이 높다. 4) 영양실조가 없는 환자에서도 술 후 약 7일 이상의 금식이 예상되면 TPN을 시행하는 것이 좋다.

일반적으로 기술평가는 무형의 기술을 대상으로 그 기술의 기술성, 사업성, 시장성을 검토하여 기술을 금액, 등급, 점수, 의견 등으로 표시하는 평가활동으로 정의할 수 있으며(Cordon, 1994), 평가목적에 따라 다양한 기술평가유형이 존재한다. 최근 기술의 사업화가 선진경제구현의 핵심 매커니즘으로 부상함(박종복, 2008)에 따라 성공적인 신기술 사업화의 선행절차로서 기술평가가 필요하다고 할 수 있다. 일반적으로 신기술의 사업화 관련 선행연구 및 그것을 추진하는 기관들은 기술의 기술성과 사업성을 중심으로 신기술을 평가하고 있다. 하지만, 현재까지의 신기술 사업화 목적의 기술평가와 관련한 선행연구는 기술성과 사업성의 균형 있게 평가하지 못하고 있다. 따라서 본 연구에서는 신기술의 평가를 위해 기술의 기술성과 사업성을 동시에 고려할 수 있는 기술평가지표를 개발하였다.
