This paper analyzes some problems for the architecture of TMN-based integrated network management systems and presents a CORBA-based integrated network management system, which maintains transparency and scalability of distributed managed objects and reliably provides interoperability between heterogeneous networks and systems. In this paper, the proposed system model has been applied to the TMN based management systems and then analyzed for qualitative evaluation of the system performance. To implement the proposed system, two different types of model have proposed: one is a system using a CORBA gateway and the other is a system, which transforms all managed objects into CORBA objects. The former model is adequate for the implementation of a short-term integrated network management system and the latter one is good for a long-term management system.

In recent years, as the demands of VBNS(Very high speed Backbone Network Service) and VDSL(Very high-data rate Digital Subscriber Line) increase, the development of kernel parts of optical communication such as PLC(Planar Light Circuit), Coupler, WDM elements increase. The alignment and the attachment technology are very important to fabricate the optical elements for communication. In this paper, the mechanism of rotational stage are studied. with the three different method and the results of them are applied to the design of the system. The performance test of resolution and travel is performed.

유상피성 육종은 매우 드문 악성 연조직 육종으로, 전형적인 경우들은 주로 젊은 남성의 수부, 전완부와 같은 신체의 원위부에 피하 혹은 심재성 피부 종괴로 발생하며, 조직학적 소견상 적은 비정형성을 나타내는 유상피성 세포와 방추형 세포의 증식에 의한 다발성 결절 형태의 배열을 보인다. 최근에 전형적인 유상피성 육종과 조직학적 유사성을 가지나 더 공격적인 형태인 proximal-type 유상피성 육종이 보고되었으며, proximal-type은 전형적인 유상피성 육종에 비하여 현저한 유상피성 세포의 발현과 매우 심한 비정형성을 나타내며, 세포가 매우 크고, 소포성 핵과 뚜렷한 핵소체를 보이며, 자주 rhabdoid 세포의 양상을 띈다. 임상적으로는 전형적인 형태에 비하여 호발 연령이 조금 늦고, 주로 체간부에, 특히 골반, 회음부, 생식기 등과 같은 심부에 발생하고, 더욱 공격적인 양상을 나타낸다. 저자들은 13세 소녀에서 원발부위를 알 수 없는, 골반내에 발생한 proximal-type 유상피성 육종 1예를 경험하여, 문헌 고찰과 함께 보고하는 바이다. Epithelioid sarcoma is a rare malignant soft-tissue sarcoma with an unknown histiogenesis, typically presenting as a subcutaneous or deep dermal mass lesion in the distal portions of the extremities of young adults. Recently, a more aggressive, so-called 'proximal-type' epithelioid sarcoma has been reported. In contrast to conventional epithelioid sarcoma, the proximal type is characterized by a predominantly large cell epithelioid cytomorphology, marked cytologic atypia, and frequent occurrence of rhabdoid features in most patients. Proximal-type epithelioid sarcoma has a predilection for appearing in the genitalia, especially the vulva, penis, pelvis and buttocks. Also this lesion appears to be somewhat more aggressive or at least metastasizes earlier than the conventional epithelioid sarcoma. We report a 13-year-old girl who presented with a buge mass filling the pelvic cavity which was painful, hard and fixed on palpation, and was radiologically diagnosed as a malignant germ cell tumors on the CT scan. The mass was surgically excised and pathologically proved to be an proximal-type epithelioid sarcoma of unknown origin.

Acinar cell carcinoma is a rare tumor that represents 1~2% of al1 pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-o1d man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased ^(18)F-fluorodeoxyglucose (FDG) uptake Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the Pancreas The patient underwent a total gastrectomy three months later because of gastric recurrence Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabme.

복합용도건물 유형에 따른 에너지평준화에 관한 연구

이준호,홍원화 대한건축학회 2003 대한건축학회논문집 Vol.19 No.3

The restriction of fossil fuel consumption by UNFCC(United Nations Framework Convention on Climate Change) brought nation-level policies to cut down energy consumption. It is in great need to revaluate the efficiency of the current architectural tendency towards multi-use and large-size buildings which causes the increase of consumption. The present research is to find energy-saving models by three steps, examining consumption characteristics of single-use buildings, by which assuming model buildings and supposing energy consumption patterns according to mixed-use types. The ratio of 2 mixed uses with energy saving characteristics were established as 5:5, which were designed as Housing+Office and Housing+Hospital. The optimum mix ratios of the 2 models were derived, as a result, 4:6 in winter season and 9:1 in summer season. The analysis is a basic step of simulated mix-use building and its mix ratio and is to be used as reference for the decision of mix ratio for presupposing energy consumption.

李相和,李俊熹 동아대학교 환경문제연구소 1984 硏究報告 Vol.7 No.2

T₄ and T_(6) treated test alloy were investigated by the D. S. C. analysis. Low temperature exothermic reaction which caused by dissolution of G. P. Zone was formed during the aging at room temperature, and has relationship to the preformed precipitates, by which classical precipitation path can be changed to the modified precipitation path. In the D. S. C. curve, the region of low temperature endothermic reaction is due to the dissolution of G. P. Zones, and the region of high temperature endothermic reaction is associated with the disslution of equilibrium phase η, and the formation of η', η, and the growth of η appear at the middle region of temperature. Kinetics which related to the precipitation process of high strength Al alloy can be investigated with the aid of D. S. C. analysis more easily. The relative stability of precipitate in matrix grows down in the sequence of η, η' and G. P. Zone, and is mainly depended upon the activated entropy.

The upper stream area of the north Han river, which is located around the Chunchon city of the Kangwon province, is out essential resources, which supply clear drinking water to the capital city of out conutry, Seoul. This area has also produced stone and aggregate resources required for building and road constructions in the capital area For preservation and planned-development of this area, in this study, we have developed an integrated management system for natural resources, based upon geological information technologies. This system includes powerful tools and functions for resource management such as information collection, edition, processing, modeling, analysis, and visualization. As a result, this system may give us capabilities to efficiently handle a variety of resource management issues such as the analysis of underground resources, the planning and development of natural resources, the protection of environment and their related projects.
