유비쿼터스 컴퓨팅 환경을 위한 에이전트 시스템과 인포메이션 버스 어댑터간 상호 운용성을 위한 기법
박상용,한승욱,윤희용,Park, Sang-Yong,Han, Seung-Wok,Youn, Hee-Yong 한국정보처리학회 2006 정보처리학회논문지 A Vol.13 No.6
The role of autonomic and intelligent agents in various environments is getting more important as demand on ubiquitous computing grows. The agents exchange information using the ACL (Agent Communication Language) to autonomously solve the problems. In this paper we propose a way of efficient interoperability technique between the agent framework built based on the international standard FIPA(Foundation for Intelligent Physical Agents) and the CORBA event service-based information bus adapter developed by us. The design and implementation of EMTI (Efficient Message Transport Interface) allowing communication between the information bus adapter which is non-agent platform and JADE platform are presented and its performance is evaluated by letting them exchange a large amount of messages. 유비쿼터스 컴퓨팅 환경의 관심과 요구가 고조됨에 따라 다양한 상황에 능동적이고 지능적인 에이전트의 역할이 점차 중요시 되고 있다. 이러한 에이전트는 ACL(Agent Communication Language)을 통신 언어로 사용하여 에이전트간 자율적인 상호 운용성 문제를 해결하기 위해 정보를 교환 한다. 본 논문에서는 소프트웨어 에이전트의 국제표준화 단체인 FIPA(Foundation for Intelligent Physical Agents)의 에이전트 프레임워크와 CORBA 이벤트 서비스 기반으로 자체 개발한 인포메이션 버스 어댑터간의 효율적인 통신을 보장하는 상호 운용성 기법을 제안한다. 비에이전트 플랫폼인 인포메이션 버스 어댑터와 JADE 플랫폼간 통신(메시지 교환)을 보장하기 위한 인터페이스인 EMTI(Efficient Message Transport Interface) 설계 및 구현 방법에 대해 살펴보고, 이기종 플랫폼간 다량의 메시지를 송수신하여 그 안정성과 성능에 대해 평가한다.

The prophylactic effects of Hijikia fusiforme on bone metabolism were examined using in vitro indices of bone formation and resorption. As the indices of bone formation, osteoblast proliferation and differentiation were measured through mitochondrial enzyme activity [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay] and bone marker alkaline phosphatase (ALP) activity. The aqueous extract of H. fusiforme stimulated the proliferation of the human osteoblast-like cell line MG63 and the ALP activity of the mouse osteoblast-like cell line MC3T3-E1. Moreover, extracellular matrix mineralization was accelerated by the addition of H. fusiforme. As the indices of bone resorption, differentiation of the murine macrophage/osteoclast precursor cell line RAW 264.7 by receptor activator of nuclear factor-jB ligand (RANKL) was measured as tartrate-resistant acid phosphatase–positive multinucleated cells, which were suppressed by H. fusiforme. Additionally,H. fusiforme lowered the secreted amount of RANKL that is required for the osteoclastic differentiation and activation, but the amount of osteoprotegerin as a decoy receptor for RANKL was not affected. The bone-protective effects of H. fusiforme in estrogen-deficient ovariectomized rats were also investigated. Osteoporosis was induced in female Sprague–Dawley rats by ovariectomy for 15 weeks, and then H. fusiforme was orally administered at a dose of 100 mg/kg of body weight every day for 6 weeks. Bone mineral density in the group orally administered H. fusiforme was increased, compared with ovariectomized rats, but not significantly (P > .05). Oral administration of H. fusiforme improved microarchitecture of bone in terms of bone volume (bone volume/total volume ratio) and trabecular separation (P < .05). The amounts of osteocalcin and C-telopeptide type I collagen in serum were measured as the biomarkers for bone formation and resorption. The level of osteocalcin in serum was increased, but not significantly. However, the level of C-telopeptide type I collagen in serum was significantly decreased (P < .05). When the results are taken together, the present study indicates that H. fusiforme might be useful in the treatment of osteoporosis.

Although it is the first transportation method to apply the 'Ground Effect' applied to aircraft to ships, WIG ships, which are classified as 'Ships' operating on the water under international law. The pilot aptitude test, which has the effect of preventing safety accidents in advance, has not yet been established as a legal system in S. Korea, after being certified by the Korean Register of Shipping (KR) for the first time in the world in March 2020. Therefore, the purpose of this study is to ensure that identifying the importance, recognition, correlation, etc. of the tools and items of aptitude testing, from a group of experts, can be used appropriately for future development of legal aptitude testing tools. As a method of study, the questionnaire method was used, and the analysis confirmed that the tools used on aircraft and ships could be used appropriately. In particular, Due to the characteristics of the WIG ships, it was confirmed that it is necessary to develop more specifically in the future, the operational qualifications and physical fitness items, which are the aptitude evaluation items.
완전무치악 환자에서 임플란트 하이브리드보철물을 이용한 전악 수복 증례

치아의 상실은 저작 및 발음 등의 구강 기능의 저하와 치조골 소실을 가져오며 또한 자신감 결여로 심리적 문제까지 초래하는데, 이는 완전 무치악 환자에서 더 큰 문제를 야기한다. 본 증례의 환자는 다수치아의 상실 및 잔존치 동요도 때문에 임플란트를 이용한 고정성 보철을 원하다는 주소로 내원하였다. 치주적으로 예후가 불량한 모든 잔존치를 발치 하였으며 상하악 완전 무치악에서 임플란트를 이용한 하이브리드보철물을 이용하여 전악 수복 시행하였다. 최종치료 후 심미적, 기능적으로 만족스러운 결과를 얻었기에 이를 보고하고자 한다. Loss of teeth may not only imply impaired oral function and loss of alveolar bone but is also often accompanied by reduced self-confidence. This results in a larger problem with the fully edentulous patient. The patient introduced in this study showed multiple missing teeth and mobility of remaining teeth and wanted to have fixed dental prosthesis using implants. Remaining teeth were extracted because of periodontally bad prognosis. This article reports a satisfactory clinical and esthetic outcome of full mouth rehabilitation using implant hybrid prosthesis in fully edentulous patient.
