Melanoma of the scalp is rare condition and seems to be to have a poor prognosis than melanoma of other portion of the body. We had 2 patients suffering from malignant melanoma of scalp. Their charts were reviewed for epidemiologic data, location, Breslow thickness, lymph node involvement and outcome. The therapeutic treatment was wide excision and skin grafting or free flap reconstruction. The early recognition of all the nevi at scalp and proper follow-up of the lesion are key stones to eradicating the changing mole and to preventing this thread to life.

In this paper, we propose Bayes estimators of the finite population mean based on heavy-tailed prior distributions using scale mixtures of normals. Also, the asymptotic optimality property of the proposed Bayes estimators is proved. A numerical example is provided to illustrate the results.

The study on the intonational characteristics is concentrated on the lowering of the pitch level that is described as declination and downstep. The Taegu dialect, which has phonological accentual system, has these phonetic characteristics in affirmative sentences or Yes-No Question sentences. But there is the opposite phenomenon in WH question sentences in Taegu dialect. When the accent of interrogative word in the sentence intial position is LHL, intonation pattern shows a continuous upward movement, indicating that intonation pattern of Taegu dialect is influenced by not only grammatical system but also accentual system.

The purpose of this study is to suggest the estimation model of' amenity environment' by Perceived Envionmental Quality Index(PEQI) model. A questionnaire survey was carried out for 연e study area of Taegu-Kyungbuk region. Sampling size was 838(427 of Taegu and 411 of Kyungbuk residents by stratified sampling of each region's(7 Gu for Tae-gu, 7 Cities 61 Gun far Kyungbuk) population. The survey was done during Sep. to Nov, of 1996. The suggested model was composed of four estimation categories and 16 Indicators. The four categories were 'Cleanness 61 Quietness', 'Naturalness & Harmony', 'Beauty 61 Comfort' and 'Environmental Conservation Efforts'. And each category has several individual Indicators. The weighted means of satisfaction were different by each region. Suseong-gu, Dalseogu, Joong-gu(Taegu), Bumcheon, Andong, and Cheondo(Kyungbuk) showed high enoronmental satisfaction, but Dong-gu. Seo-gu(taegu), Youngcheon, and Pohang(Kyungbuk) showed lower environmental satisfaction. By Analytic Hierarchy Process(AHP) of weighting values for each categorirs, 'Enoronmental Conservation Efforts' was estimated as the most Important(value of 0.367), and 'Naturalness 61 Harmony'(0. 242),'Clenness & guletness'(0.225), and 'Beauty & Comfort'(0.166) were Important respectively. Total PEQI's were estimated as 48.0 for Taegu, and 53.3 for Kyungbuk. PEQI's for each regions were between 46.2(Dong-gu) and 59.9(Kimcheon). The validity of the suggested model was verined by factor analysis. The four factors were identnied as the same categories and indicators. Finally, The LISREL+7 model was suggested as estimauon model of 'Amenity Environment' for Taegu-Kyungbuk region.

This review highlights the ontogenesis and the differentiation of motor neuron in spinal cord, and introduce the survival motor neuron(SMN) which is associated with growth and survival of motor neurons. The differentiation of floor plate cells and motor neurons in the vertebrate neural tube appears to be induced by signals from the notochord. This signal is Sonic hedgehog(Shh). The early development of motor neurons involves the inductive action of Shh. The SMN gene is essential for embryonic viability. SMN mRNA is also expressed in virtually all cell types in spinal cord, including large motor neurons. The SMN protein is involved in RNA processing and during early embryonic development is necessary fer cell survival. Two SMN genes are present in 5q 13 in humans: the telomeric gene(SMNt), which is the SMA-determining gene, and the centromeric analog gene(SMNc). The majority of transcripts from the SMNt gene are full length but, major transcripts of the SMNc gene have a high degrees of alternative splicing and tend to have little or no exon 7. The SMN is involved in the RNA processing(the biogenesis of snRNPs and pre-mRNA splicing), the anti-apoptotic effects, and regulating gene expression.
