Congenital self-healing reticulohistiocytosis(CSHRH) consists of multiple disseminated papulonodular skin lesions of varying sizes and regress spontaneously in several weeks to months with little or no scarring, and until recently it has been regarded as a benign cutaneous disease without systemic involvement. However, involvement of organ systems other than the skin has been described occasionally and recurrence of disease at sites distant from the skin has been documented. We present a case of CSHRH in a full termed, normal spontaneous vaginal delivered male neonate. He had reddish colored nodules on the whole body without systemic symptoms. Four weeks later, the skin lesions cleared concurrently with bony involvement of the skull. Because multiple organ systems can be involved and recurrences are possible, long-term follow-up of these patients is indicated. (Korean J Dermatol 2003;41(4) : 466~469)

Sinus histiocytosis with massive lymphadenopathy(SHML) is a benign, generally selflimited pseudolymphomatous disease that typically appears with cervical massive lymphaclenopathy. Extranodal involvement including skin occurs in the 28% of the cases. We report a case af SHML in 51 year-old male who had several, prominent firm masses ranging from 1-10cm in the cervical, axillary, inguinal areas and multiple, plum colored nodules and plaques in the face, trunk for about 10 years. The histopathological findings of cervical lymph node, facial nodule showed dense heavy infiltration of large histiocytes with abundant pale eosinophilic cytoplasm in the subcapsular and medullary sinuses of lymph node and dermis of skin. No atypical cells suggesting malignancy is seen in the infiltrates. The patient had been treated with combination of prednisolone and vinblasstine, but he expired 1 month later.

We present a case of lymphangioma circumscriptum in a 17 year-old girl according to tihe clinical and histopathological findings. This case is unusual in that lesions developed on the vulva and thigh without preceding lymphedema. Our patient had a plaque of grouped vesicle-like papules resembling frog's apawn on The both labia majora of vulva and several scattered, skin tag like soft papules on the right upper thigh of theree years duration. Histopathologic findings showed variable sized, dilatated lymphatic channels lined by single layer of normal endothelial cells confined to the only upper dermis.

In this study, a direct in-situ observation of fracture and crack tip deformation behavior under a wedge loading has been carried out in a scanning electron microscope (SEM) using an HSLA steel and an AISI 4340 steel. A specially designed wedge loading stage was adapted in an SEM for the observation of crack propagation on the surface of small double cantilever beam (DCB) specimens. The results for the HSLA steel with simulated microstructures of the heat affected zone of welding show that the formation of shear bands is primarily responsible for the initiation of microcrack at notch tip and crack propagation. A fracture mechanism for the local brittle zone (LBZ) phenomena has also been identified as the initiation of microvoids by the interfacial decohesion between the ferrite matrix and martensite islands. For the 4340 steel, voids were first observed to form around the large MnS inclusions and the plastic deformation became localized into intense shear bands between these voids as they grew. The failure eventually occurred along these shear bands, although fine microvoids would form around alloy carbides within the shear hands. This in-situ SEM technique has been found very useful for studying the microstructural aspects of crack initiation and crack growth behavior on the surface

본 연구는 사범대학 교육이 어떤 의미를 가지는 지에 대해 탐색하고자 하는 연구이다. 이를 위해 최근에 사범대학을 졸업하고 교직에 들어 온 초임교사 6명을 대상으로 그들의 사범대학시절의 경험에 대한 심층면담 연구를 수행하였다. 연구 결과, 그들에게 있어 사범대학에서의 교과내용학 과정은 ‘학자 되기 위한 것 배우기’, 교과교육학 과정은 ‘빈약한 것 배우기’, 교직과목과정은 ‘교육학 이론 배우기’, 교육실습 과정은 ‘수박 겉핥기’, 잠재적 교육과정은 ‘가랑비에 옷젖기’ 과정인 것으로 나타났다. 그리고 현행 사범대학 교육은 교육 목표(지향) 측면에서는 ‘이론중심 패러다임’, 교육 구조 측면에서는 ‘연계성 부족’, 교육 내용 측면에서는 ‘교사 준비 미흡’ 등의 특징이 있음을 논하였다. 연구 결과를 바탕으로 사범대학의 이론중심 패러다임의 개선을 위한 구체적인 방안들이 구안되어야 하며, 사범대학 교육 내용을 좀 더 강화시킬 필요가 있고, 사범교육의 표준, 혹은 준거가 시급히 마련되어야 함을 제안하였다.
