Epithelioid hemangioma, the term which was first used by Enzinger and Weiss, is synonymous with angiolymphoid hyperplasia with eosinophilia. It defines a lesion occurring usually in the dermal and subcutaneous tissue of the head and neck, characterized by localized, marginated and relatively symmetrical proliferation of the capillaries around a medium-sized vessel with an epithelioid hyperplasia of endothelial cell. There is a marked inflammatory reaction composed of lymphocytes and eosinophils. We report a case of epithelioid hemangioma associated with nevus flammeus in a 53-year-old male. Histology revealed typical feature of epithelioid hemangioma that proliferation of dilated vessels with prominent endothelial cells surrounded by dense lymphoid cell infiltrates but no eosinophils were identified.

N/A Background:Pityriasis rosea is an acute inflammatory dermatosis with an unproven etiology. The typical clinical feature consists of an initial, single herald patch followed by development of smaller, disseminated, papulosquamous, ovoid macules. However, an unusual papular type of pityriasis rosea is relatively common in children and it shows similar clinical characteristics to pityriasis lichenoides. Objectives:Our purpose was to observe the clinical and histologic features of pityriasis rosea and pityriasis lichenoides, and differentiate two diseases in children. Methods:Sixteen children with pityriasis rosea and nineteen children with pityriasis lichenoides were investigated clinically and histologically. Results 1. Clinically, pityriasis rosea may be differentiated from pityriasis lichenoides by the existence of herald patch, short duration, the uniformity of size and shape, and residual pigmentation. 2. Focal parakeratosis, intraepidermal vesicle and papillary derma edema are more common in pityriasis rosea. In contrast, deep dermal infiltration, dyskeratosis, epidermal necrosis and confluent parakeratosis are more common in pityriasis lichenoides. 3. Comparing to the plaque type, a papular type of pityriasis rosea shows more involvement in the extremities with longer duration. Histologically, parakeratosis and papillary dermal edema are less and spongiosis is more commonly observed in papular type. Conclusions:Pityriasis rosea in children often shows papules especially on the extremities, similar to that of pityriasis lichenoides. However, from the results in this study, we believe that two diseases can be differentiated if both clinical and histologic findings are carefully studied. (Korean J Dermatol 2001;39(12):1349~1355)

러시아어 무인칭 구문(impersonal constructions)의 통사적 구조에 대한 재고찰 : A Minimalist Approach

김형섭(Kim Hyoung Sup) 한국노어노문학회 2010 노어노문학 Vol.22 No.4

본 논고는 러시아어에 나타나는 무인칭 구문의 통사적 구조에 대한 재해석으로 형식 가주어의 존재를 인정하지 않았던 기존 연구의 토대와는 달리 러시아어에서도 언어 보편적인(language universal) 현상들이 나타난다. 문장의 구조적 특성상 형식 가주어가 심층구조에 존재하지만 가시성 조건(Visibility Condition) 을 충족시키지 못해 음성적으로 실현되지 못한 결과로 해석한다. 이론적 배경으로는 부르치오의 일반화(Burzio’s Generalization) 이론을 적용함으로써 의미역과 대격 할당의 전제조건인 주어자리를 채워주어 다른 일반적인 문장과 동일하게 통사적으로 파생한다. 통사적 파생의 기본원리는 X- 바 이론(X’Theory) 과 더불어, 탐침(Probe)과 목표(Goal)사이의 자질공유 역할을 담당하는 메커니즘인 일치(Agree) 이다. 영어에서는 주격과 [+ 지시성] 자질에 의해 형식 가주어 [it] 이 발음되지만, 러시아어에서는 주격과 [- 지시성] 에 의하여 음성적으로 발음되지 않는 차이점을 보인다. 다시 말해, 가시화 조건을 충족시키지 못해 음성실현이 되지 않는 것이다. 무인칭문의 서술어는 주격의 부재로 인해 항상 3 인칭, 단수, 중성의 형태를 사용하는데 이를 디폴트(default)라 한다. 디폴트 일치는 형식적 일치의 하나로 성-수-격이 일치하는 문법적 일치와는 다르다. 주어의 최초 결합 장소는 VP 지정어 자리이며 필요에 따라 vP 지정어 또는 TP 지정어 자리로 이동하기도 하고, 그 자리에 머무는 경우도 있다(in-situ). 능동자의 의미역 할당에 필요한 vP 지정어 자리가 없는 비대격 동사는 VP 안쪽에서 의미역을 할당 받으며, 대격 할당을 받지 못하는 이유로 시제T로 부터 주격을 할당받고 확대투사원리(EP, Extended Projection Principle) 에 의해 문장의 주어 자리인 TP지정어 자리로 옮겨간다. 이와는 달리 러시아어의 무인칭 구문은 심층구조에서 주격주어를 가지고 있으며, 그로 인해 대격을 할당할 수 있다는 것이 차이점이다. 가시화되지 못한 주격주어는 주절의 주어가 부동사구의 주어와 같을 때에만 생략하는 부동사의 사용을 통하여 간접적으로 증명이 되고 있는 것이다. This paper investigates the syntactic structure of impersonal constructions, i.e., absolute, dative, and accusative impersonal sentences, on the basis of the assumption that there is a null expletive subject phonologically invisible on the specifier of TP. This approach is in contrast to the Russian tradition disapproving of a covert syntactic subject in nominative. This research is based on Burzio’s Generalization that a verb (with an object) case-marks its object if and only if it theta-marks its subject. In accusative impersonal sentences, like in personal sentences, the light verb little v possesses a full set of phi-features and T is not a defective functional category, which has EP (Extended Projection Principle), [nom] case, and uninterpretable [utense:] features. Being a functional category responsible for tense, nominative case, and EP, T serves for syntactic derivation as Probe, which searches for its Goal with nominal features. This mechanism is called “Agree”, in which interpretable and uninterpretable features are shared reciprocally and valued among them. The reason why a subject on the specifier of TP in impersonal sentences does not spell out phonologically overtly is that it does not satisfy the Visibility Condition that case [case:] and referentiality [+/-Ref] features must be marked in order to be visible for an argument. In the case of Russian accusative impersonal sentences, these two requirements of [nom] and [-Ref] features prevent arguments from spelling out overtly. With regard to the position of a subject, the initial merge of a subject occurs on the specifier of VP and later moves up to the specifier of vP to receive a theta-role of [agent] or stay in the initial position without move (in-situ). Russian accusative impersonal sentences are different from unaccusative sentences in that the latter have a nominative subject, which originates from an internal complement within VP, while the former have a nominative subject, which cannot spell out phonologically due to the failure to satisfy the Visibility Condition. The lack of a nominative subject triggers the use of default agreement for Subject-Predicate Agreement. Default agreement is the last resort to solve non-agreeing cases between subjects and predicates. Default agreement is one of the two types of formal agreement: one is grammatical agreement [+AGR/+Ref] and default agreement [+AGR/-Ref]. Semantic agreement [-AGR] occurs due to semantic factors between an agreement controller and an agreement target. Furthermore, accusative impersonal verbs cannot form their own participles or gerunds. However, Covert null expletive subjects in impersonal verbs can serve as a controller of gerunds used in a subordinate clause. The use of gerunds entails the existence of their controllers in the matrix clause, since gerunds can be used only when subjects in gerundive clauses are the same as those of main clauses. The controllability over gerunds firmly supports the assumption that there is a phonologically covert null expletive subject in nominative.

Charpy V-Notch test is commonly used to evaluate fracture toughness. However, since the region to be evaluated is limited to bulk material due to the specimen size required, individual evaluation of micro-structures on weldment is very difficult. In this study, ASP(Advanced Small Punch) test was carried out to evaluate material degradation and fracture toughness on the B.M, W.M and each micro-structures of HAZ for X20CrMoV121 and 2.25Cr1Mo steels with artificial aging time. In addition, to evaluate fracture toughness and material degradation of B.M and W.M of X20CrMoV121 steels with aging times, CVN (Charpy V-notch) test was performed. And then the correlation between ASP and CVN test on X20CrMoV121 steels was obtained. Furthermore, through this correlation, material degradation property of each micro-region of the HAZ in weldment, which was impossible to be evaluated by the CVN test, can be estimated and determined.

댐건설(建設)로 인한 5대수계(大水系) 본류(本流)의 유황변화(流況變化) 분석(分析)

이진원,김형섭,우효섭,Lee, Jin Wo,Kim, Hyoung Sup,Woo, Hyo Seop 대한토목학회 1993 대한토목학회논문집 Vol.13 No.3

한강, 낙동강, 금강, 섬진강, 영산강 등 우리나라 5대강 본류 주요지점에서의 광범위한 수문자료(水文資料)를 토대로 유황분석(流況分析)을 수행하였다. 우리나라 하천유량 자료의 신뢰도상의 한계를 감안하여, 특히 저수위시수위(低水位時水位)-유량(流量) 관계곡선의 검토 동 본 유황분석에서 이용된 유량자료의 검토에 세심한 배려를 하였다. 본 연구에 의하면, 우리나라 주요 수계의 유황은 상류에 다목적댐 건설로 상당히 개선된 것으로 나타났으며, 이러한 유황개선 효과는 주요 수계의 하상계수(河狀係數)가 댐 건설이전 자연상태에서 300-400 정도이었으나 댐 건설이후 100-300 정도로 감소한 사실과 본 연구에서 제시된 '유황계수(流況係數)'가 대폭 감소한 사실 등에 의해서 확인되어진다. 수계별로는 한강과 영산강의 유황은 상대적으로 안정되어 있고 금강과 섬진강의 유황은 불안정한 것으로 나타났으며, 이러한 결과는 금강과 섬진강에 새로운 수자원 개발의 필요성을 간접적으로 시사하고 있다. An analysis of flow duration characteristics of the five major rivers in Korea was conducted with extensive river flow data available. The analysis reveals that, for most river stage-gauging stations at the rivers investigated in this study, the flow duration characteristics have changed drastically at some stations after major dammings in the river basins. Streamflow variability. which is newly defined in this study as the ratio of the 2.5 percents (or 10 day) duration discharge over the 97.5 percents (or 355 day) duration one, was also reduced by the dammings. The result of the study shows that the Han and the Yeongsan rivers have relatively small flow variation, while the Seomjin and the Keum rivers have relatively large now variation, which implies that the latter two river basins need new water resources development.

오상호 ( Sang Ho Oh ),김형섭 ( Hyoung Sup Kim ),기정혜 ( Jung Hye Kee ),장성남 ( Sung Nam Chang ),김동건 ( Dong Kun Kim ) 대한피부과학회 2002 대한피부과학회지 Vol.40 No.4

Cutaneous T cell lymphoma, pleomorphic. small/medium-sized is a primary cutaneous lymphoma that consist, of less than 30% of large, pleomorphic T cells and mostly small/medium-sized, plemorphic T cells stained negatively CD30. This entity presents clinically with o several red-purple nodules without patches & plaques and histopathologically infiltration of small/medium-sized T cells with a dense nodular or diffuse pattern in the dennis. Usually cellular infiltration consist of atypical lymphocytes without eosinophils plasma cells and neutrophils but there are cases infiltrated with atypical lymphocytes and eosinophils. We report a case of cutaneous T cell lymphoma, pleomorphic, smell/medium-sized in a cast 55-year-old male who was presented with hard nodules on both elbows, both ankles, left 1st interdigital web, both wrists and both lateral sides of thigh. Histopathological findings showed diffuse and nodular infiltrates with atypical lymphocytes and eosinophils in the dennis not involving die epidermis. Bone scan, bone marrow biopsy and CT scan taken to find out involvement of other organs showed neutral finding except for eosinophilia at bone marrow biopsy.

We report a case of Hunter syndrome with extensive Mongolian spots. A 4-year-old male baby presented with asymptomatic, firm, raised, ivory-colored papules and nodules which coalesced to form ridges in a reticular pattern (pebbling of the skin) and were arranged bilaterally and symmetrically over the scapulae, and lateral aspects of the thighs. Large Mongolian spots were present over the back. He has low intelligence, short stature, a protuberant abdomen with hepatosplenomegaly, and broad hands with clawlike contractures of the distal interphalangeal joints. The result of qualitative analysis of mucopolysaccharride was positive for the dermatan sulfate and heparan sulfate in the urine. Massive mucinous materials which stained positively with alcian blue were observed from collagen fibers throughout the dermis of skin biopsy specimen. Metachromatic granules within fibroblasts stained with toluidine blue were also seen. This case is reported for its rarity and the typical skin lesions, the recognition of which may be helpful in diagnosis and genetic counselling.

스테로이드 Pulse 요법에 의해 치료된 웨버 크리스찬 병(Weber-Christian Disease)

조영훈 ( Young Hun Cho ),박준수 ( Jun Su Park ),김형섭 ( Hyoung Sup Kim ),이광길 ( Kwang Gil Lee ),정기양 ( Kee Yang Chung ) 대한피부과학회 2002 대한피부과학회지 Vol.40 No.12

Weber-Christian disease is an inflammatory disease of subcutaneous fat tissue which is characterized by relapsing, febrile tender nodules and histologically lobular panniculitis. Many cases originally considered as examples of Weber-Christian disease were later found to be other diseases when lobular panniculitis was reclassified, and some authors believe that Weber-Christian disease should no longer be considered as a distinctive entity. However, there are still occasional cases which cannot be diagnosed as other specific diseases but have the characteristic manifestations of Weber-Christian disease, and they attest to the fact that Weber-Christian disease could be a distinctive disease entity. We report here a case of Weber-Christian disease in a 22-year-old female who was treated successfully with steroid pulse therapy. (Korean J Dermatol 2002;40(12) . 1557∼1560)
