문서요약은 여러 개의 하위 주제로 구성되어 있는 문서에 대해 문서의 복잡도를 줄이면서 하위 주제를 모두 포함하는 요약문을 생성하는 것이 목적이다. 본 논문은 그래프 분할을 이용하여 하위 주제별로 중요 문장을 추출하는 요약시스템을 제안한다. 문장별 공기정보에 의한 단어의 연관성 분석을 통해 선정된 대표어를 이용하여 문서를 그래프로 표현한다. 그래프는 연결정보에 의해 하위 주제를 의미하는 부분 그래프로 분할되며 부분 그래프는 긴밀한 관계를 갖는 문장들이 클러스터링된 형태이다. 부분 그래프별로 중요 문장을 추출하면 하위 주제별 핵심 내용들로만 요약문을 구성하게 되어 요약 성능이 향상된다. The main purpose of document summarization is to reduce the complexity of documents that are consisted of sub-themes. Also it is to create summarization which includes the sub-themes. This paper proposes a summarization system which could extract any salient sentences in accordance with sub-themes by using graph division. A document can be represented in graphs by using chosen representative terms through term relativity analysis based on co-occurrence information. This graph, then, is subdivided to represent sub-themes through connected information. The divided graphs are types of sentence clustering which shows a close relationship. When salient sentences are extracted from the divided graphs, summarization consisted of core elements of sentences from the sub-themes can be produced. As a result, the summarization quality will be improved.

Weber - Cockayne형 단순성 수포성 표피박리증 - 전자현미경 소견

Epidermolysis bullosa simplex(EBS) is a group of autosomal dominantly inherited genetic disorders characterized by blistering due to mechanical- stress-induced degeneration of basal epiderrnal cells. Recently, it was discovered that EBS is induced by keratin 5 and 14 gene mutations. Weber Cockayne(W-C) EBS is the mildest type, with blistering concentrates primarily on palar and plantar regions, and basal cell cytolysis by keratin filament perturbations is present. Herein we report a case of W-C EBS with its ultrastructural findings. Electron microscopy showed cytolysis and separation of the basal epidermal cells, mainly at the subnuclear cytoplasm. The cyto- plasm of basal cells showed edema, loosening and intact rnitochondria. Besides the cytoplasmic changes, the nucleus also showed lytic degeneration. Characteristically, dense condensation of tonofilarnent was observed, which suggests that W-C EBS is. also a disorder of keratin. (Kor J Dermatol 1997;35(1): 214-219)

H.264 코덱을 사용한 고성능 DVR 시스템 개발에 관한 연구

이일주(Lee, Il-Joo),임성준(Lim, Sung-Jun),채현석(Chae, Hyun-Suk) 한국산학기술학회 2009 한국산학기술학회논문지 Vol.10 No.1

DVR 시스템은 비디오 데이터를 저장/재생해야 하기 때문에 대용량의 비디오 데이터를 압축하는 것이 매우 중요하다. 압축 방법으로 기존의 MPEG-4 압축을 사용하는 고성능 DVR 제품군은 국내외 적으로 다수가 있으나, 성능은 대부분 입력 영상에 비해서, 열화된 영상 크기인 CIF(D1/4)크기를 압축하는 DVR이 대다수이다. 본 논문에서는 DSP를 이용하여 M-JPEG과 H.264 코덱을 구현하였다. M-JPEG은 다채널 모니터링을 위한 네트워크 전송용으로 사용하였으며, H.264는 Baseline Profile을 지원하여 기존의 MPEG-4 압축에 비해 2~4배 압축률 상승시켰다. 그 결과 가로 720픽셀, 세로 480픽셀의 고해상도를 지원할 수 있게 되었다. It is very important for a DVR system to compress mass video data because they should be able to store/playback of video data. There are several high efficient DVR products using ordinary MPEG-4 compression for data compression. But most of them support only CIF(D1/4) image, which means degraded image quality in comparison with input image source. In this paper, M-JPEG and H.264 Codec are realized using DSP. To multiple channels system M-JPEG is used for data transmission through network, and Data compression rate is improved as about 4 times as ordinary MPEG-4 compression by supporting Baseline Profile of H.264. As a result, high resolution with the width 720 pixels and the height 480 pixels can be supported.

Warty dyskeratoma is a rare, well-circumscribed epidermal tumor that frequently aries as a single lesion on the skin of the head or neck of middle aged or older persons. Its histopathological features include : suprabasilar clefting with villous proliferations of the connective tissue papillae into the clefts ; acantholytic and dyskeratoic epithelial cells,basilar hyperplasia, and hyperleratosis. We report three cases of warty dyskeratoma describing clinical and histochemical fea tures. (Kor J Dermatol 1992;30(4):564-568)

Present communication and network environment have been moving rapidly toward wireless and mobile base from existing wired internet base. This change of trend influences greatly on business methods accordingly. Therefore many enterprises are trying hard to adopt mobile business in order to gain competitive edge of their products and they are in need of more effective and stable mobile solutions. However, the method of establishing optimal mobile computing environment and how to handle existing business process and use vast amount of database are still needed. Therefore this paper tries to realize a mobile middleware system as a mobile business establishment supporting tool that could link various computational resource on wired internet with wireless LAN, mobile phone network, and mobile devices. To accomplish that specific goal, this paper provides a powerful tool of mobile and wireless application data access that could expand the line of business already set up in general enterprises easily and rapidly into mobile environment. When this suggested solution is applied in the field of industry, it can economically change legacy business process into mobile environment without having to change existing logic and resources at all.

Background : Beckers nevus is a benign lesion that may be congental or acquired, macular or papular, hairless or hypertrichotie. Objective : Our pcrpose was to describe the clinical findings of Eeckers nevus and to establish a method for the histologic diagnosis of Beckers nevus. Methods : We reviewed PF skin biopsies and their clinical finding from 28 patients with Beckers nevus during a 10 year period from January 1981 to January 1991. Results : The results were summarized as follows. A Clinical characteristics 1. Sex distribution showed of male predominence with male female a ratio of 1.5:1. Age of onset was predominent in less that 5 years old and puberty. 2. The lesions were located on the trunk(24 cases), head & neck(8 cases), extremities(6 cases), and were repsilateral in 26 cases, bilateral in 2 cases. 3. The lesions were accompanied by hair in 17 cases(61%). The shaies of the lesions were reticulated (75 %), patch(18%), mottled(7%). 4. Hairs were distributed as follows : abdomen(100%), scapula(100 %), extremities (83%), cheek(80 %), neck(67 %), chest(40%). All lesions of the face had follicular papules. 5. Associated skin diseases were : smooth muscle hamartoma(3 cases), striae distensa(2 cases), steroid acne(2 cases), pigmented nevus(2 cases), and verruca plana(1 case). B. Histopathologic characteristics 1. The lesions were accompanied with plugs in 21 cases, which were follicular, acrosyringeal, epidermal. 2. Elongation of the rete ridge and hyperpigmented basal cells were observed in the epidermis in all cases. 3. The shape of the rete ridge in Beckers nevus has its characteristic appearance, which is single, bridging and reticulated. Single, bridging and reticulated shapes cexisted in 17 cases(61%). 4. Inflammatiry cell infiltrations were present in all of the upper drmis, in which melanophages(21 %), hair follicles(89%) and smooth muscle hamartoma(3cases) w ere observed Conclusion : These findings indicated that the shape of the rete ridge in Beckers nevus has its characteristic appesrance and can be useful for the diagnosis of Beckers nevus.

Impetigo herpetiformis is a form of pustular psoriasis that occurs during pregnancy and may be life-threatening. The pathogenesis and etiology of impetigo herpetiformis is not clear, but several reports have associated onset of this disorder with hypocalcemia, hypoparathyroidism, and the use of oral contraceptives. The typical lesions are erythematous patches that are studded with tiny superficial pustules particularly coalescing at their margins causing pain, and a burning sensation. Laboratory findings include an elevated erythrocyte sedimentation rate, increased peripheral blood leukocyte counts, hypoalbuminemia, and in severe cases, hypocalcemia. The histopathology is the same as that of pustula psoriasis. Our patient, a 31 year-old female (Intra Uterine Pregnancy 28 weeks), was admitted to our hospital due to generalized skin eruption and severe constitutional symptoms. Her clinical features, laboratory and histopathologic findings were compatible with that of impetigo herpetiformis. In spite of our all efforts, intrauterine fetal death was noted at her 33rd week of pregnancy. We report a case of impetigo herpetiformis terminating in fetal death with the review of literature. {Kor J Dermatol 1997;35(1): 150-154}

Hypereosinophilic syndrome is characterized by marked eosinohia and eosinopbilic infiltrition of various organ-systems without any identifiable underlyin sathologic conditions such as hypersensitivity, drug eruption, parasitic infestat,ion, malignant tuinc, and autoimrnune and infectious d iseases. A 31 year-old male had weight loss, abnormal peripheral cirrultiction both extremities and two distinct skin lesions. One showed rice sized, erythematous follicular popules on both extremit.ies and trunk and the other showed a walnut sized, gangrenous ulcer on the left 2nd finger tip. The patients skin lesions and circulation defect. improved after retrnent with steroid and the blood eosinophilia returned to normal. (Kor J Dermatol 1995; 33(1); 104-108)
