Subcutaneous fat necrosis of the newborn is an uncommon transient panniculitis which is characterized by asymptomatic, firm to rubbery, purple-red, erythematous subcutaneous nodules and plaques occurring during the first 4 weeks of life. Characteristic histologic findings are areas of fat necrosis associated with inflammation in the subcutaneous tissue and needle-shaped clefts with radial arrangement in fat cells as well as foreign body giant cells. We report a case of subcutaneous fat necrosis in a 9 day-old male who had suffered from hard erythematous nodules on both upper arms. (Korean J Dermatol 2003;41(7) : 985~987)

Several horizons of soil wedge structures have been identified in the paleolithic sites with hillslope and alluvial environments in South Korea. Their formation ages of them are rather ambiguous because of time gaps between the age of pedogenesis and that of sedimentary formation. The discrepancy in the formation age is also derived from the lack of proper materials for radiometric datings. A number of soil wedges are distributed at two different levels in soil-sedimentary profiles of paleolithic sites. The lower soil wedge, showing a cryoturbation in a reddish brown layer, was formed at about 65,000 yr BP while the upper one, characterized by a dark brown muddy sand layer was formed at about 22,000 $\sim$ 18,000 yr BP. Between these two layers are a few soil wedge layers that are rather discontinuous and small in scale. These soil wedges are thought to have been to be formed during last glacial time on the bases of the cryoturbation structure and the radiometric ages. Stone artefacts are most commonly found in these dark brown soil profiles. 남한 구석기 유적지층은 주로 구릉지나 강가에 발달한 토양 $\cdot$ 퇴적층으로서 이들 토층 내에는 토양쐐기 구조가 서로 다른 2 매 혹은 그이상의 층준에 발달하여 있다. 이들 토양쐐기의 형성 시기에 대하여 다소모호한데 이는 토층을 구성하는 퇴적층의 집적 시기와 토양화 과정의시기 간에 불일치에 기인한다. 또 다른 형성 시기 불일치에 대한 다른이유는 적절한 방사성 연대측정 물질을 발견하기 어려움에 기인한다. 구석기 유적지에 나타나는 토양쐐기는 토층의 상부와 하부에 2 매로나타나는 수가 많다. 특히 기반암 상부에 나타나는 적갈색 토층을교란시킨 하부 동결구조 (lower cryogenic structure)는 약 65,000년전후, 그리고 상부의 암갈색 니사질 토층 내 발달한 토양쐐기 (soil wedge)는 약 22,000 $\sim$ 18,000년 전에 형성된 것으로 추정된다. 이양자 사이에는 연속성이 다소 미약하며 소규모 토양쐐기가 나타나기도한다. 이들 토양쐐기 구조는 추운 기후 특징을 나타내며, 방사성탄소연대측정 결과로 보아 모두 마지막 빙기 (last glacial)에 형성된 동결구조로 해석된다. 대부분의 구석기들은 상부의 암갈색 동결구조 토층과연계되어 산출된다.

Objectives The purpose of this study was to examine the automatic attentional bias to disease/body-related stimuli in individuals exhibiting somatization tendencies using Event-Related Potential (ERP). Methods The participants were classified according to somatization and control groups based on the somatization symptom scales of the Symptom Checklist-90-Revised and Somatosensory Amplification Scale scores. ERP were recorded in the somatization and control groups while participants were performing the task to respond with neutral (standard stimuli) or disease/body-related words (target stimuli). We compared N100, P200, and P300 ERP components between the two groups. Results In the somatization group, the reaction times to disease/body-related words were faster than for neutral words. In ERP analysis, N100 to standard stimuli was not observed in the somatization group. The somatization group showed higher P200 and P300 amplitudes to target stimuli than standard stimuli. On the contrary, in the control group, no difference in P200 and P300 amplitudes was observed between target and standard stimuli. Conclusion It is suggested that individuals exhibiting somatization tendencies have automatic attentional bias to disease/body-related stimuli and interpret disease/body-related stimuli as self-relevant stimuli.
