Woringer-Kolopp disease, so called pagetoid reticulosis, is most likely represent a chronic localized from of reticulosis. A 24-year old male patient visited with asymptomatic slowly enlarging, scaly single patch on his left thigh for 10 years duration. Histopathologic studies were taken with H-E stain, D-PAS, transmission electronmicroscopy and monoclonal antibody(OK6) tissue stain. Infiltration of atypical cells showed in the lower portion of epidermis like pagetoid patterned, none in dermis. It seems to be that the cell in this case probably originated from the stimuIated T-lymphocyte.

A 50-year-old woman with lupus erythematosus profundus of about a year's duration was reported. The patient had no history of discoid lupus erythematosus or systemic lupus erythematosus. Dermatologic examination revealed two, firm, freely movable, well demarcated, subcutaneous plaques, with mildly erythematous overlying skin, measuring 2 x 2 cm (right), 5 x 5 cm (left), was present on the both deltoid region. Histopathologically, this showed panniculitis. Diret immunofluorescence studies showed IgG and IgM deposition on the dermoepidermal junction.

A 3-year-old-male had the appearance of red urine at birth and developed recurrent bullae in sun-exposed area of the skin, erythrodontia, alopecia, splenomegaly and hemolytic anemia, We observed coral red fluorescence of the teeth and urine under Wood's light and detected excessive excretion of the uroporphyrin in the urine and coproporphyrin in the stool wlth inreased porphyrin in the blood. Fluorescence of erythrocyte was demonstrated by:fluoreacence microscopy. Histologic findings showed subepidermal bulla with PAS-positive hyaline deposits around the blood vessels and revealed IgG deposits in the wall of blood vessels and dermo-epidermal junction by direct immunofluorescence.

This report presents a case of a 17-year-old-girl who developed a, Kaposis varicelliforrn eruption(eczema herpeticum) during oral prednisolone therapy in order to control pemphigus foliaceus. Diagnosis was made by the history, clinical feature and histologic examination. Within 24 hours after the initiation of therapy with ribavirin(Viramid), new lesions had ceased to develop.

Controllable pitch propeller(CPP) can move blade pitch angle and change vessel's direction without reversing device Crank pin shear stress of trunnion bearing type assembly is a smaller than collar bearing type assembly. Trunnion bearing type assembly is a stronger than collar bearing type assembly. For improved quality and optimized designing of CPP, the structural analysis is need to compare collar bearing type with trunnion bearing type assembly by various methods. Also the results of it's analysis is necessary to choose type of CPP hub and structure mechanism in connection with vessel purpose.

This thesis is focused on the comparison between Numerical Calculation and FEM Analysis by ANSYS by software for Impeller Shafting System of Low Noise Large Cavitation Tunnel. The impeller shafting system are considered buoyancy effect to influence driving shaft in the water that reason why the shaft diameter 800㎜ above. The shafting are arranged two solid shafts at forward end, three hallow shafts in the water and one hallow shaft on the tail. The bearings are arranged one self aligned journal bearing on the tail shaft and one axial thrust with two journal bearings on the motor shaft. The strength calculation was done by MathCAD.

메타개체군의 구조와 이주에 관한 이해는 종 보존을 위해서 필요하다. 본 연구는 붉은점모시나비 서식지에서 MRR 방법으로 나비의 이주패턴을 분석하고 패치연결성을 추정하였다. 그 결과 194(수컷: 137, 암컷: 57)개체가 포획 되었으며 이중 93 (수컷: 73, 암컷: 20)개체가 재포획되었다. 이주 분석에서 이입율은 23-150%, 이출율은 28-53%으로 나타났다. 패치면적과 이입 이출 개체수와의 회귀분석에서는 상관관계를 보이지 않았으며, 먹이식물 수와 이입 이출 개체수와의 회귀분석에서도 상관관계를 보이지 않았다. 그러나 이입 개체수와 패치간 거리와의 분석에서는 높은 상관관계를 보였다. 따라서 나비의 이주는 패치거리가 가까울수록 빈번하게 일어나고 있으나 패치의 면적이나 먹이식물 량과 관계가 없는 것으로 나타났다. 나비의 이주에서 암컷보다 수컷이 매우 활발한 것으로 나타났다. 패치의 위치에 따른 이주 패턴의 분석 결과 패치 네트워크상에서 중앙에 위치한 패치가 양쪽 끝에 위치한 개체군을 이어주는 역할을 하고 있으며 근접한 거리에 있는 패치들간 이주가 멀리 떨어진 패치에 비해 빈번한 이주가 일어나는 것을 보여주었다. 따라서 붉은점모시나비의 이주에 있어서 근거리에 위치한 패치들간 교류가 활발히 일어나고 있으며 패치와 패치를 이어주는 징검다리 역할을 하는 패치가 존재할 경우 교류가 더 활성화된다는 것을 제시하고 있다. Understanding the metapopulation structure and movement of a species are required for conserving the species. In this paper, migration patterns and connectivity of patches of a threatened butterfly, Parnassius bremeri Bremer, were postulated using the mark-release-recapture (MRR) technique in a habitat located in the mid-southern region of the Korean peninsula. A total of 194 individuals were captured (137 males and 57 females) and, of them, 93 individuals (73 males and 20 females) were recaptured during the MRR experiment. The migration analysis showed 23-150% immigration and 28-53% emigration. There were high correlations between the migrating individuals and the distance between patches, but there was no correlation between migrating individuals and patch size or between migrating individuals and the number of host plants. Consequently, the migration of butterflies occurred frequently between closer patches, while patch size and quantity of the food plant had minor effects on migration behavior. Additionally, males migrated more frequently than females. Analysis of the migration patterns of P. bremeri showed that the central patch played an important role on linking patch groups and more frequent migrations were monitored between nearby patches than between the remote patches. This study suggested that active migrations take place between the neighboring multiple patches and these are accelerated if there is a stepping-stone patch between them.
