유러닝/컴퓨터과학 : 연구 망 그룹을 위한 논리 네트워크의 표현과 관리에 관한 연구
윤대중 ( Dae Joong Yoon ),안성진 ( Seong Jin Ahn ),정진욱 ( Jin Wook Chung ) 한국컴퓨터교육학회 2010 한국컴퓨터교육학회 학술발표대회논문집 Vol.14 No.2
최근 과학기술연구망은 고 에너지 물리, 우주·천문, 기상·기후, 바이오, 건설 등의 특정 연구 그룹간의 논리 네트워크를 구축하여, 해당 목적에 맞는 일종의 그룹별 사설 네트워크에 대한 구현이 많이 요구되는 상황이다. 이러한 요구에 대응하여 과학기술연구 망의 그룹별 논리 네트워크에 대한 연구 망 NOC 차원에서의 관리 프레임워크가 요구되고 있다. 따라서 과학기술연구 망 네트워크 인프라 자원의 운영정보, 구성정보, 성능정보, 장애정보 등에 대한 데이터를 국제 표준에 맞추어 설계된 명세 시스템에 표현하고 통합적인 관리가 가능하도록 해야 한다. 이를 통해 현재 과학기술연구 망의 효율적인 관리는 물론 국제 연구 망 운영센터간의 운영 협업 및 유기적인 운영 기술 공유가 이루어지게 될 것이다. 본 논문에서는 과학기술연구 망의 특정 응용 별 논리 네트워크를 표현하고 안정적으로 네트워크를 관리하는 기술에 대해 연구하고자 한다.

Papulonecrotic tuberculid (PNT) and Pityriasis lichenoides et varioliformis acuta (PLEVA) have been in controversy in their pathogeneses and entity itselves. Authors reviewed litera,tures of the two dermatoses with observation of nine casea of PNT from 1979 to 1981 and evaluated whether PNT could be also classified as PLEVA. The results were a,s follows: 1. By the review of literatures PNT and PLEVA showed great similarities in their clinical aspects including shape of cutaneous lesions, course, favorite age and subjecive symptoms. Histopathological overlappings were also found. 2. Of the nine cases of PNT authors observed, seven cases were histopathologically PLEVA and four cases could be thought PLEVA also clinically. But way six cases were treated by anti-tuberculous drugs. 3. The incidence of other tuberculous signs and results of tuberculin skin tests were all significant in the nine cases above. With the above observations it seems that PNT is one of the causes of PLEVA and thus could be a kind of PLEVA.

Serum alanine aminotransferase activity was increased to the highest level 24 hours after single CCl_4 injection, whereas alcohol dehydrogenase(ADH) was not detected in the sera of both control and CCl_4 poisoned rabbits. Among various rabbit organs observed, ADH activity was found only in the liver and in the stomach. Hepatic ADH and acetaldehyde dehydrogenase activities in chronic CCl_4 poisoned rabbits were severely reduced to 77% and 15% of control group respectively. Since ethanol metabolism which occurs mainly in the liver was greatly reduced in chronic CCl_4 poisoned rabbits, ethanol clearance rats can be expected as a useful indicator for the diagnosis of chronic liver disease.

A single pedunculated slowly growing tumor was found on the right thigh of a 49 year-old woman. The tumor cells were largely those of eccrine poroma but the degree of the extension of the tumor cell masses, which occupied most of the dermis, were like that of invasive basal cell epithelioma. In addition there were areas where the cells show considerable atypia and dyskeratosis. These histopathological findings were compatible with eccrine poroepithelioma first reported by Mishima and Morioka(1969). The histologic differences between eccrine poroma, eccrine poroepithelioma and eccrine porocarcinoma were discussed.

Proliferating trichilemmal cyst is a fascinating follicular neoplasm. Prior to its recognition, the tumor was misinterpreted as squamous cell carcinoma both clinically and histologically. The incidence of the lesion is rare and we can not find this case in the Korean literature. Authors have found a large, lobulated, hemorrhagic progressively growing tumor on the scalp of a 66 year-old woman. By its appearance it was hard to think the lesion was a benign tumor. Histological examination confirmed the diagnosis of proliferating trichilemmal cyst. Local excision and skin graft brought about complete healing of the lesion.
습진성구순염병변을 보인 Lymphadenosis benigna cutis의 1례

Clinical features of lymphadenosis benigna cutis is not simple. They have shown wide variations in their cutaneous manifestation. We belive the case presented herein adds one more clinical variation of the disease. The patione, a 45-year old woman, developed recurrent pruritic edematous, sometimes OOzing crusted lesions on the lower lip and then central upper lip including the philtrum. The histological pictures of lymphadenosis benigna cutis, well developed multiple lymphoid follicles in dermis, and eczematous epidermis.
