Background : Neurofibiomat,osis type 1(NF-1) is a multisystemic disorder of genetic ori gin, affecting one in every 3000 to 4000 people. It is clinically important in the aspect of dermatology, pediatrics, orthopedic surgery, neurology, neurosurgery and ophthalmology. Objective : The purpore of this study was to elucidate the clinical characteristics of NF-1 in Korean people. Methods : We carried out a retrospective study on 112 patients which were compatible to the diagnostic criteria of Riccardi and Neurofibromatosis Conference Statement. The results were compared with other western studies. Results : The age of onset, sex ratio, family history of neurofibromatosis, and clinica features of cafe-au-lait spot, neurofibroma, and axillary freckinings did not differed from western countries. However, some characterist,ics of NF 1(e.g. Lisch nodule) were not as sessed in the most of the cases and incomplete evaluations of the systemic diseases wen found. Conclusion : In this study t.he clinial features of NF-1 did not differ from western coun tries in many aspects. A more intensive evaluation of patient,s status is needed to manag; NF-1 patients appropritely. (Kor J Dermatol 1995;33(6): 1091-1098)

Petrological, paleomagnetic, geomorphological and structural studies on the southern part of, so called, Chugaryeong rift valley, have been carried out in order to clarify the nature of the rift valley. Three stages of volcanic activities characterized by Jijangbong acidic volcanic rocks and tholeiitic and andesitic basalt of Cretaceous age(?), and Jongok Quaternary olivine basalt occurred along the Dongducheon fault line. Jijangbong acidic volcanic rocks distributed in the central part of the studied area consist of rhyodacite, acidic tuff and tuff breccia, which are bounded by Dongsong fault on the east and Daegwangri fault on the west. The Jongok basalt differs from those of Ulrung and Jeju islands in mineralogy, chemical composition and differentiation. Jongok basalt distributed along the Hantan river dilineates the vesicles curved toward downstream direction and increment of numbers and thickness of lava flow toward upstream direction. These facts suggest that lava flowed from upstream side of the river. Rectangular drainage patterns also support the presence of the Dongducheon, Pocheon, Wangsukcheon and Kyonggang faults which were previously known. LANDSAT image, however, does not show any lineaments which could be counted as a graben or rift valley. Displacement of Precambrian quartzite and Jurassic Daedong supergroup along the southwestern extension of the Dongducheon fault shows the right lateral movement. The Paleomagnetic study of the tholeiitic and andesitic basalts from Baegeuri, Jangtanri and Tonghyeonri located at 2. 3km east, 0km east, and 1.5km west of Dongducheon fault respectively shows that their VGP(Virtual Geomagnetic Pole) being to intermediate geomagnetic field of short duration which suggests that they formed in almost same period. Mean VGP of Jongok basalt is located 82.4N and 80.6E. This is in good coincidence with worldwide VGP of Plio-Pleistocene indicating that Jongok basalt was extruded during Plio-Pleistocene epoch, and suggesting that the studied area has been tectonically stable since then. From the present study, the tectonic episode of the region is concluded as following three stages. 1. The 1st period is worked by the Daebo orogeny of Jurassic during which granodiorite was intruded in Precambrian basement. 2. The 2nd period is the time when right lateral strike-slip fault of NNE-SSW direction was formed probably during late Cretaceous to Paleogene and the Jijangbong acidic volcanic rocks and the older basalts were extruded. 3. The 3rd period is the time when the fault was rejuvenated during Pliocene or Pleistocene accompanied by the eruption of Jongok basalt. As a conclusion, geologic structure of the studied area is rather fault line valley than graben or rift valley, which is formed by differential erosion along the Dongducheon fault suggesting a continuation of the Sikhote-Alin fault. The volcanic rocks including the Jijangbong acidic rocks, tholeiitic-andesitic basalt and olivine basalt are associated with this fault line.

생명기후분석시스템(BioCAS)을 이용하여 서울시 전역의 폭염사례일 기온, 인지온도(PT), 초과사망률(rEM) 분포를 분석하였다. 분석 해상도는 25m 였으며, 사례일은 2012년 8월 5일이었다. 분석 결과는 관측된 사망률 및 내원환자수 자료와의 비교를 통해 평가되었다. 2004년에서 2013년의 폭염 원인인 사망률 자료와 2006년에서 2011년의 국민건강보험공단의 폭염 내원환자수 자료를 이용하여 행정구별 폭염 건강위험 자료를 추출하였다. 자료 비교를 위한 공간 해상도는 사망률 및 내원환자수 자료의 해상도인 행정구 단위였다. BioCAS에서 분석된 사례일 최고 인지온도 및 초과사망률 분포 자료는 행정구별 공간 평균, 최대, 최소 및 누적값으로 변환된 후 건강피해자료와 상관분석이 수행되었다. 분석 결과 일 최고 인지온도 및 초과사망률의 공간 평균값은 건강피해를 설명하지 못하는 것으로 나타났다. 대신 일 최고 인지온도의 공간 최솟값은 사망률과, 공간 최댓값은 내원환자수와 상관관계가 있는 것으로 나타났다(각각 r=0.53, r=0.42). 즉, 밀집된 건물에 의해 생겨나는 공간 최댓값은 낮 동안의 일사병 발생과 내원환자수 증가에 영향을 주었고, 식생에 의해 나타나는 공간 최솟값은 밤 동안의 열 스트레스를 감소시켜 사망률에 영향을 주었던 것으로 판단된다. 한편 분석된 초과사망률(rEM)은 공간 최댓값과 내원환자수가 상관관계가 있었지만(r=0.52) 사망률과의 상관관계는 인정되지 않았는데, 이것은 연령별 인구구성 차이에 따른 기저 폭염위험도 차이 등 행정구별 불균일성을 고려하지 못한 한계가 나타난 것으로 판단된다. 개별 건물과 식생의 열적 효과는 공간 평균보다 최대, 최소 등 그 분포가 중요한 것으로 나타났다. 이러한 고해상도 분석기술은 도시의 건강영향평가를 통해 도시개발에 관한 경제성 분석에 활용이 가능할 것으로 기대된다 The Bio-Climatic impact Assessment System, BioCAS was utilized to produce analysis maps of daily maximum perceived temperature (PT<sub>max</sub>) and excess mortality (rEM) over the entire Seoul area on a heat wave event. The spatial resolution was 25 m and the Aug. 5, 2012 was the selected heat event date. The analyzed results were evaluated by comparing with observed health impact data - mortality and morbidity - during heat waves in 2004-2013 and 2006-2011, respectively. They were aggregated for 25 districts in Seoul. Spatial resolution of the comparison was equalized to district to match the lower data resolution of mortality and morbidity. Spatial maximum, minimum, average, and total of PT<sub>max</sub> and rEM were generated and correlated to the health impact data of mortality and morbidity. Correlation results show that the spatial averages of PT<sub>max</sub> and rEM were not able to explain the observed health impact. Instead, spatial minimum and maximum of PT<sub>max</sub> were correlated with mortality (r=0.53) and morbidity (r=0.42), respectively. Spatial maximum of PT<sub>max</sub>, determined by building density, affected increasing morbidity at daytime by heat-related diseases such as sunstroke, whereas spatial minimum, determined by vegetation, affected decreasing mortality at nighttime by reducing heat stress. On the other hand, spatial maximum of rEM was correlated with morbidity (r=0.52) but not with mortality. It may have been affected by the limit of district-level irregularity such as difference in base-line heat vulnerability due to the age structure of the population. Areal distribution of the heat impact by local building and vegetation, such as spatial maximum and minimum, was more important than spatial mean. Such high resolution analyses are able to produce quantitative results in health impact and can also be used for economic analyses of localized urban development.

There are increasing number of allergic patients due to the increasing outdoor activities and allergenic pollens by local climate changes. Korea Meteorological Administration provides daily forecasts for pollen allergy warnings on the Internet. The forecast models are composed of pollen concentration models and risk grade levels. The accuracy of the models was determined in terms of risk grade. Pollen concentration models were developed using the observed data during from 2001 to 2006 and accuracy was validated against the data during from 2010 to 2011. The accuracy was different from location to location. The accuracy for most tree species was higher in April than that in May. The accuracy for weed species was higher in October than in September. Our result suggest that the models presented in this study can be used to estimate daily number and risk grade of pollens.

Chongyang tungsten ore deposits, one of the most important tungsten mines in South Korea, are open space filling hydrothermal vein deposits embedded in Precambrian biotite gneiss and Cretaceous (?) granite porphyry. Some wolframito-bearing quartz veins are closely associated with quartz porphyries which strike about N15˚-25˚W and dip 80˚SE to vertical. Mineralization took place in near vertical vein systems of 5 to 2000 meter long in the biotite gneiss and granite porphyry stock during early Cretaceous and Tertiary (?) period. The hydrothermal mineral paragensis has indicated that there were two major stages: vein and vug stages. The principal vein mineral is wolframite in a gangue of quartz with small amount of fluorite, pyrite, beryl and carbonate minerals. Present in minor amounts are molybdenite, bithmuthinite, native bismuth, arsenopyrite, galena, chalcopyrite, pyrrhotite, sphalerite and scheelite. Fluid inclusion study from the minerls at Chongyang mine reveals that vein stage fluids attained a temperature range of 200℃-355℃ and vug stage 160℃-350℃. The filling temperatures show the higher range of 200˚-355℃ in quartz and 280℃-348℃ in beryls, whereas the lower - emperature range of 283℃-295℃ in rhodochrosite and 160˚-253℃ in fluorites. These temperatures are in reasonably good agreement with mineral paragnesis in this ore deposits. Wolfamite minerals were analysed for major components, WO₃, MnO and FeO by wet chemical method. Chemical analysis indicates that they contain 70.56-71.54% WO₃, 8.52-10.01% MnO and 10.00-11.58% FeO. MnO/FeO ratios of wolframites shows the range of 0.78-0.94 which maybe indicates a comparatively high temperature type of hydrothermal deposits.
