태백산분지 캠브리아기 세송층의 퇴적상이 정밀 주상도 작업과 야외조사에 의해 분석되었다. 결과로 5개의 퇴적상이 세송층 내에서 인지되었으며 이들은 석회질 단괴를 포함한 셰일상, 망상형 와케스톤-팩스톤상, 엽리질 실트암상, 세립 및 중립질 사암상, 석회 잔자갈 역암상 등을 포함한다. 퇴적상 분석과 함께 수행된 수직적 상변화에 대한 연구는 세송층이 외대륙붕 및 내대륙붕 환경 하에서 상대적인 해수면의 하강에 의해 퇴적되었음을 지시한다. 특히, 세송층 최상부에 10 m 두께의 세립 및 중립질 사암층의 천해성 퇴적양상은 동 시기인 로렌시아 대륙의 Steptoean Stage(Dunderburgia) 퇴적층 내에서 나타나는 퇴적상 변화와 매우 유사한 양상을 보인다. 이러한 두 대륙 사이의 동 시기 퇴적층의 퇴적상에 관한 비교는 세송층의 퇴적이 캠브리아기 중기 후반에서 캠브리아기 후기 초반 동안에 있었던 전 지구적인 해수면의 하강의 영향을 잘 반영하고 있음을 암시한다. 또한 세송층 상부구간의 세립 및 중립질 천해성 사암층 내에는 시퀀스 층서학적으로 의미가 있는 하나의 층서불연속면이 인지된다. 이러한 층서불연속면은 로렌시아 대륙에서 정의되었던 Sauk II-III 시퀀스 경계면에 대비될 수도 있다. 따라서 본 연구에서 도출된 결과는 태백산분지 내 캠브리아기 중기 및 후기 퇴적층(예; 세송층)들의 지역 간 대비에 있어서 새로운 층서적 사고의 틀로 사용될 수 있으며, 향후 대륙 간 층서대비에 있어 매우 유용한 정보를 제공해 줄 수 있다. Sedimentary facies of the Middle to Upper Cambrian Sesong Formation, Taebacksan Basin, are analyzed using detailed field mapping and stratigraphic section measuring. As a result, five sedimentary facies are recognized in the formation, which include lime nodule bearing shale facies, anastomosing wackestone-packstone facies, well-laminated siltstone facies, fine to medium sandstone facies and lime pebble conglomerate facies. Together with sedimentary facies analysis, study on vertical facies variation indicates that the Sesong Formation was deposited in an outer to inner shelf during relative sea-level fall. Especially, shallow marine aspects of the upper part of the Sesong Formation including 10-m-thick, fine to medium-grained sandstones appear to be very similar with the shallow marine strata accumulated during the Steptoean Stage (Dunderbergia) in Laurentia. These lithofacies comparisons of coeval strata between two continents suggest that sedimentation in the Sesong Formation reflects the influence of global sea-level fall occurred during the late Middle Cambrian to early Late Cambrian. As well, a stratigraphic discontinuity surface that may have sequence stratigraphic significance is recognized within the shallow marine sandstone beds of the uppermost Sesong Formation. This stratigraphic discontinuity surface may correspond to the Sauk II-III sequence boundary in Laurentia. Therefore, results delineated in this study will use a new stratigraphic paradigm for regional correlation of the Middle to Late Cambrian strata (e.g., the Sesong Formation) in the Taebacksan Basin, and will provide very useful information on intercontinental stratigraphic correlation in the future.

We report a case of trichilemmal carcimoma in a 82-year-old man who resented an ulcerative tumor. Initially, a crusted mass was observed on the scalp and with subsequent removal of the crust, purulent and ulcerative lesion was seen. After treatment with sensitive antibiotics for 8 days, purulent discharge was markedly decreased in the lesion. Histopathologic findings showed clear cells tumor with trichilemmal keratinization. The tumor cells stained positive to PAS, sensitive to diastase and showed negative findings to CEA, EMA and S-100.

The tens, hyperkemtotic vascular stains is a peculiar form of capillary malformations commonly called as giokeratoma or verrucous hemangioma. Hyperkeratotic vascular stains present at birth and consist of vascular dilatation and epidermal proliferation manifested as hyperkeratosis. acanthosis, and papillomatosis. Some authors insisted that angiokeratoma and verrucous hemangioma are not proper terms because they are not true tumors but malformations due to their lack of endothelial proliferation. Wide and deep excisions have been preferred as curative therapy. The patient was a 9-year-old girl with multiple. linear, bluish black colored, hyperkeratotic plaques on her let lower leg. The red patches at birth had slowly enlarged and had become verrucous. Some satellite lesions had also developed. Histopathologic examination showed dilated capillaries filled with red blood cells in the papillary dermis and subcutaneous fat layer. The carbon dioxide laser was used to remove hyperkeratotic plaques. The flash-lamp pumped-pulsed dye laser and intense noncoherent pulsed light were used to remove satellite lesions and vascular lesions for a year. One of the lesions resistant to laser therapy was completely excised. Because multiple hyperkeramtic vascular stains are often impossible to be excised completely, laser therapy may be tried as the first choice.

Removal of carbon monoxide from gas flow by NMD was investigated in a 4.2cm I.D. fluidized bed. The optimum loading amounts of palladium oxide on the natural manganese dioxide was determined in a fixed bed. The mean diameter of the NMD particle was performed by 90% conversion of CO with the natural manganese dioxide in a fluidized bed. The effect of L/D, which is residence time of gas, of PdO/NMD and NMD on the CO conversion was investigated in the freely bubbling region. It was found from the experiment that the particle size(0.359mm) of the NMD and the loading amount(0.5wt.%) of palladium oxide was optimum. The addition of PdO on NMD increase the ability of oxidation in low temperature. For NMD, the conversion of CO is linerly increased with the L/D at the entire range, but for PdO/NMD to L/D=1.5 only.

Acantholytic dyskeratosis is seen in Darier's disease, transient acantholytic dermatosis and warty dyskeratoma. It is also occasionally observed incidental histological finding in pityriasis rosea, pityriasis rubra pilaris and is occasionally found in linear epidermal nevus. A 10-month-old boy presented linear hyperkeratotic plaques on the right sole and the left hand along with erythematous scaly papules on the posterior neck, the left axilla and the face. Histological findings showed acantholytic dyskeratosis with common histopathological findings of epidermal nevus. Acantholytic dyskeratosis is an occasional finding in linear epidermal nevus, but has been rarely reported in an infant(5 cases reported in 20 years). We report a case of linear epidermal nevus with acantholytic dyskeratosis in an infant.

요골동맥에 발생한 Glomus Tumor : 증례 보고

Glomus tumor, a rare benign vascular tumrz arising from the neuromyoarterial apparatus, is usually located at the tip of digits, especially at subungual region. Most of this tumor present typical symptoms such as hypersensitivity to cold, severe pain and point tenderness but frequently misdiagnosed as neuroma, gout or causalgia. Concerning about the origin of the glomus tumor, there were few written reports about extra-digit vascular origin glomus tumor especially that occurred at forearm artery. Recently we experienced a glomus tumor which arised at forearm radial artery and reported with review of literatures. A 31-year-old female admitted to our department with pulsating, slow growing, tender mass at her left foreann for about 1 year. After diagnostic evaluation of ultrasonography and magnetic resonance angiography, surgical resection was performed under the diagnosis of radial artery aneurysm but the histologic final diagnosis made by special immunohistochemical stains was glomus tumor originated from radial artery. The postoperative course was uneventful up to 2 years of follow up.
