Scapular Osteocutaneous Free Flap 을 이용한 하악재건 3 예

윤근철,이택종,유장열,이향주 大韓成形外科學會 1989 Archives of Plastic Surgery Vol.16 No.3

Although there are many methods and donor sites in the mandibular reconstruction by microvascular tissue transfer, the iliac bone with deep circumflex iliac artery has been used most commonly. Meanwhile, Acland introduced scapular osteocutaneou free flap using the periosteal branch of circumflex scapular artery in 1985. In reconstructing 3 cases of mandibular composite defects, we adopted the scapular osteocutaneous free flap to avoid the handicaps of iliac bone free flap i.e bulkness, difficulties in mucosa-bone dissociated reconstruction etc.. After resonable period of follow-up, we reviewed the cases and methods of reconstruction and concluded that the scapular osteocutaneouos free flap hs following merits. 1. Technically easy especially in the large mucosal defect and in case the mucosal detet is not near to the bone defect. 2. Aesthetically good. 3. Structural stability is tolerable inspite of scapular bone osteotomies. And in one case we modified the procedure by elevating the bone with attached Teres major muscle belly to meet the need of soft tissue defect resulting from neck dissection.

사해사본 11QPs^(a)와 시편의 정경화

유윤종 연세대학교 신과대학 2006 신학논단 Vol.43 No.-

11Q Ps^(a) among Dead Sea Psalms Scrolls has brought the issue of canonicity of the book of Psalms since it was published in 1965 by J. A. Sanders. What is the relationship between MT and 11Q Ps^(a)? On its relationship with MT, 11Q Ps^(a) provides the following points of dispute: 1) on the order of psalms, it has commons and differences in comparison with MT, 2) it has liturgical purpose, 3) it includes a lot of non-canonical psalms, 4) it argues strongly Davidic authorship, 5) it shows the secondary feature including interpretation on fixed text. This paper pursues the issue of canonicity of the book of Psalms by the above five points of dispute. The five points of disputes do not exclude the probablility of 11Q Ps^(a)' canonicity. Most scholars argue that 11Q Ps^(a) has nothing to do with canonicity of the book of Psalms, because they consider that MT Psalms acquired its position as a canon before DSS. But Sanders and Wilson propose that 11Q Ps^(a) is under canonicity toward MT. While discussing on the five subjects on the issue of canonicity of 11Q Ps^(a), I suggest 11Q Ps^(a) is going toward canonicity and shows various historical stages on the canonicity of the book of Psalms.

This is to investigate visitors motivation and experiences in visiting theme parks in Korea. A total of 199 samples were collected and analyzed in SPSS. From the results of Factor analysis with 14 motivation variables, four underlying dimensions were identified. And also, from the results of factor analysis with 19 experience variables, 7 underlying dimensions were identified. Then, multiple regressions were ran with four independent motivation factors and 7 dependent experience factors. The implications of the findings were discussed for theme park marketers and planners.

단백 C 결핍증은 항응고인자인 단백 C의 결핍으로 혈전 색전증의 위험성이 높다. 선천성 단백 C 결핍증 중 동형접합성 단백 C 결핍증은 단백 C의 활성도가 측정되지 않을 정도로 낮고 1/25만~50만의 발생 빈도를 가지는 희귀한 질환이다. 동형접합성 단백 C 결핍증의 주요 증상은 자반성 및 괴사성 피부 병변, 반상출혈, 설명, 중추신경계의 혈전증 등이다. 본 증례는 동형접합성 단백 C 결핍증인 만 4세 여아로 치아의 전반적인 우식을 주소로 내원하였다 본 환아는 와파린 복용중이었고 치과치료시 합병증의 예방을 위해 소아청소년과에 협진 의뢰하였다. 와파린 복용 중단 시 혈전으로 인한 심각한 합병증이 예상되어 와파린을 적절하게 (INR 3~5) 복용하되 치과 치료 중 과다 출혈 시 신선냉동혈장으로 조절할 것을 권고받았다. 이 환아는 설명을 동반한 중증 장애 아이로 행동조절이 어려웠고 과다 출혈시 신속한 처치가 가능하도록 하기 위해 전신마취 하에 치과치료를 시행하였다. 저자는 치아의 전반적인 우식을 주소로 내원한 만 4세 단백 C 결핍 환아에 대하여 전신 마취 하 치과치료를 시행하였으며 다소의 지견을 얻었기에 보고하는 바이다. Protein C deficiency increases the risk of thrombosis due to the lack of anticoagulant factor protein C. Among the numerous congenital protein C deficiencies, homozygous protein C deficiency has an especially low protein C activity level, that it is almost undetectable. It is a rare disease with a probability of 1:250000~500000. The signs and symptoms of homozygous protein C deficiency include purpuric, necrotic dermatosis, ecchymosis, blindness, and thrombosis in central nervous system. A 4-year-old girl was brought to the clinic with a chief complaint of extensive caries. The child was under warfarin medication in order to prevent possible complications during dental treatment. We consulted the pediatric department. Without warfarin intake, serious complications may occur due to thrombosis during dental treatment. Therefore, certain warfarin dosage (INR 3~5) and fresh frozen plasma as a backup for excessive hemorrhage were recommended. This child was a severely disabled child with the loss of vision, and it was difficult to manage her behavior effectively. Thus, dental treatment was carried out under general anesthesia, where bleeding control would be also easier to achieve.This report presents the case of a 4-year-old girl with protein C deficiency, who has received dental treatment for extensive caries under general anesthesia.

The preparation conditions of alumina powder extracted by sulfuric acid were investigated. The raw material was domestic San-Cheong Kaolin. The experimental conditions which have an effect on the yield of alumina were varied as follows; the calcination temperature and time, the reaction temperature and time, and the acid concentration. The agglomeration of aluminum hydroxides precipitated by ammonia water was controlled by various drying methods. And the dried power was heated to obtain α-Al₂O₃for 1 hour at 1200℃. The yield of alumina was up to 58 percent under the optimum condition and its purity was 96.4 percent. The alumina particles prepared by the freeze drying method revealed narrower size distribution and less agglomerate than others.

백색부후균 Trametes versicolor(CV5) 균주에 의한 wood lignin의 분해능을 조사하였다. CV5는 활엽수와 침엽수에 속하는 여러 수종의 프로토 리그닌 분해 시 활엽수에 한해서 분해되는 특성을 보였으며, 특히 상수리나무에서 33.5%의 가장 높은 리그닌이 분해되었다. 리그닌 분해에 관련된 phenoloxidase 분비능을 Bavendamm 시험을 통해 검토한 결과 CV5는 지금까지 연구된 우수 백색 부후균과 같은 유사 반응 형태를 나타내고 있음을 확인하였다. 또한 상수리 목재 chip표면에 CV5의 균사가 생육하면서 목재조직이 부후된 상태를 주사전자 현미경으로 관찰한 결과 목섬유 및 도관에서 균사의 침투와 목재조직의 분해를 확인하고 리그닌에 대한 높은 선택적 분해력을 갖고 있음을 구명하였다. Trametes versicolor(CV5) selected as a white-rot fungus with strong lignin degrading activity, in the previous paper, was investigated on a properties of degradation of wood lignin. Lignins of hardwoods, especially oak(Querous acutissima carruth) an paulownia (Paulownia coreana Uyeki) were considerably delignified by the CV5, however, softwoods used in this experiment were not delignified. Bavendamm's reaction was positive with several phenols on agar plates for the confirmation of a phenoloxidase secreted Through the morphologies of decayed wood chip observed with the aid of scanning electron microscopy, it was found that the hypha of CV5 penetrated the ray cells and vessels caused separation of the wood cellulose.

데이터관리시스템은 문헌 정보들에 대한 정보 검색 및 관리를 효율적으로 지원하기 위한 시스템이다. 이러한 데이터 관리시스템은 하나의 테이블만으로 정보들을 관리하기 때문에 기존 데이터베이스 관리시스템에서 사용되는 조인 연산과 뷰 연산 등 많은 비용이 소요되는 연산을 제공할 필요가 없다. 본 논문은 데이터관리시스템에서 자료의 주고 정의, 처리 등을표현할 수 있는 효과적인 데이터 언어를 정의하고, 정의된 데이터 언어로 작성된 질의를 효율적으로 처리하기 위한 질의 처리기를 설계하고 구현한다. 구현된 데이터관리시스템을 위한 질의처리기는 기존 관계형 데이터 베이스 관리시스템의 질의처리기를 데이터관리시스템의 질의처리기로 사용할 때 나타나는 성능저하 문제점을 해결한다. Data management System(DMS) is a system that retrieves and manages documents efficiently. Since DMS manages the information using only one table, it does not need to provide join and view operations on DBMS that spend high cost. In this paper we define a data language that represents the structure definition and process of data in the DMS. We also design and implement a query processor to process the query processors of relational DBMS are used as a query processor of DMS, they degrade the whole system performance. The proposed query processor overcomes such a problem.
