This is a clinical and retropective study on th patients with oral and maxillofacial trauma. This study was based on a series of 917 patients were treated as in-patients, at Chon-buk National University Hospital, during the period of Jan., 1989 through Dec., 1993. The results obtained were as follows : 1. The ratio of men to women were 3.59 : 1 in oral and maxillofacial injuries, 3.92 : 1 in facial bone fractures, and 3.18 : 1 in soft tissue injuries. 2. The oral and maxillofacial injuries occurred most frequently in the third decade(32.2%), and fourth, second, fifth decade in orders. 3. The major etiologic factors were traffic accident(57.4%) and fall-down(17.1%), interpersonal accident(16.6%), and industrial accident were next in order of frequency. 4. The incidence of facial bone fracture was 72.1%, soft tissue injury 58.8%, and dental injury 40.5%. 5. The most common site of fracture were mandible(62.9%) and maxilla(19.9%), zygoma and zygomatic arch(18.7%), and nasal bone(4.7%) were next in order of frequency. 6. The most common type of soft tissue injury was laceration(51.0%). The lesion of soft tissue injuries were mostly 1 or 2 lesions and deep.

이 연구는 오·폐수에 함유된 유기물을 제거하기 위하여 일반 시멘트 콘크리트에 비해 우수한 역학적 성질을 갖는 폴리머를 이용한 현무암 다공질 석재를 개발하고, 이에 대한 물리. 역학적 특성 및 정화성능을 실험적으로 구명한 것이다. 그 결과 다공질 소재이나 강도가 높고 적당한 단위체적중량을 갖기 때문에 설치 후 안정성을 확보할 수 있고, 정화성능은 나일론 여재에 비해 떨어지지 않으므로, 현장 설치 및 시공방법에 대한 연구가 이루어질 경우 실용화가 가능할 것으로 판단된다. The objectives of this study were to develop porous media for sewage treatment facility using basalt and to explore the possibility of replacing wall structures of sewage treatment plants improve the efficiency of sewage treatment. It was shown that the porous media developed by using basalt was not as efficient as existing media. However, it is expected that the polymer porous media can be economically applied to existing waste treatment plants and help improve sewage treatment efficiency.

This paper is a study on the performance characteristics of a lithium bromide water absorption refrigeration system. The equation of the coefficient of performance is derived for a single stage cycle and the value calculated, When the evaporator temperature is at 40 ℉ and the efficiency of the liquid heat exchanger 0.75, under the assumption that the condensate in the condenser and the vapor in the evaporator are saturated. Through the calculated performance curves, the factors which influence the performance characteristics are discussed. It showed the coefficient of performance is affected by the condenser temperature and absorber temperature rather than the generator temperature, and only the water cooling systems are available when flat-plate , collectors are used as the energy source of the lithium bromide water cycle. change of Glucose.

EJB 래퍼 컴포넌트 지원 도구를 위한 CICS 코볼 시스템 및 SQL 문법 생성 규칙 개발

기존에 운용되고 있는 시스템은 새로운 컴퓨팅 기술 및 환경에 적응하기 위하여 현대화 되어야 한다. COBOL2EJB는 소프트웨어 컴포넌트로서 기존 시스템을 변화시킬 연계 도구이다. 이 COBOL2EJB는 코볼 문법을 중심으로 하고 있기 때문에 코볼에 내장되어 있는 CICS와 SQL을 지원하기엔 한계점이 있다. 이러한 한계점을 살펴보고 해결하기 위한 방안으로서 JJTREE를 소개한다. 그리고 COBOL2EJB 연계 도구의 사용성을 높이고자 IBM 코볼 소스에 내장된 CICS와 SQL을 처리할 수 있도록 JavaCC를 이용하여 문법 생성규칙을 확장하였다. With the rapid change of computing environment, much research is focusing on the modernization of the legacy systems Recently the software development mothods based on components have been used widely. A COBOL2EJB is used as a tool to transform the legacy system into the software component. Because of the lack of COBOL syntax generating rules, we can not fully support the software component The practical COBOL legacy system includes CICS and SQL commands as their additional source code. In this paper, we develop the advanced CICS/COBOL legacy system based on JavaCC to analyze a simple COBOL syntax. CICS/COBOL, and SQL

Measuring the thermophysical properties of solids in laser heating method, the material surface is coated by thin black paint layer(graphite) to minimize the effects of the laser beam reflection. But, the influence of the thin black paint layer on the surface temperature variations have been ignored. In this paper, a numerical analysis is carried out to clarify quantitatively the influence of the thin black paint layer when the material surface is heated locally. In the experiment, the material surface is heated by Ar laser beam and the surface temperature profiles are measured by an infrared thermometer.

에이전트는 독립적인 모듈로서 설계에 필요한 정보를 특성별로 분리하여 합의된 규약, 즉 에이전트 통신 언어에 따라 정보를 교환하는 것이며, 퍼지 추론 시스템은 경험 지식을 언어적 제어 규칙으로 표현하고 퍼지 추론을 이용해서 컴퓨터에 실행할 수 잇도록 한 것이다. 본 연구에서는 퍼지 추론 시스템과 에이전트 기반 시스템의 결합을 시도하고, 이를 주요치수와 선형 계수의 추론에 적용하여 선박설계에서의 응용 가능성을 검토하였다. Agent, as a independent module, exchanges the knowledge & the information which are classified by their characteristics according to shared protocol, i.e. Agent communication Language(ACL). A fuzzy inference system represents and experiential knowledge as a linguistic control rule and enables us to execute the knowledge using the Fuzzy inference. This study tries to connect Fuzzy inference system with an agent-based system and inspects its applicability to hull form design through inferring principle dimension and hull form coefficients.

This paper presents the future direction of the development and maintenance of the urban park of the Kumi city. The direction was obtained by analyzing the evaluation results on the satisfaction level of park use and the park image of the park users. The analysis results are as follows. 1) It turns out that the rest and accommodation facilities are the major facilities that uplifts the total image of the park. 2) Among the park images, the image on the pleasantness was the major image, related with the satisfaction on the park equipments. 3) The social class, who gave a bad score on the above equipments and images, is a low-aged class, who is a white class with high income as well. Therefore, it is suggested that the park maintenance plan, with emphasis on the class, is an important task.

In dorsal laminectomy for the surgical treatment of thoracolumbar disc disease in dog, the bur could slip into the vertebral canal. For the decrease of this probability of danger, osteotome was used with instruments such as bur and rongeur in dorsal laminectomy. At thoracic vertebrae (T10-T11) and lumbar vertebrae (L5-L6) area, dorsal laminectomys were performed in a dog. In observation for 3 months after surgery, the dog revealed healthy physical condition. For the confirmation of healing condition at 3 months after dorsal laminectomy, two surgical sites were exposed by incision. Excellent healing response was observed with no adhesion and fibrosis in the vertebral canal.
