This study investigated the morphology of sea-stacks in the Cheju island and the development processes of it and the sea-stacks development in relation with geological structures, especially joints. The results are as follows: 1. 11 sea-stacks developed in all study areas are uniformly distributed to each shore of the Cheju island. 2. By the sea-stack's scale 6-15m height and 1-10m width of sea-stacks are much distinguished. when we see the sea-stacks, site, the headland is most distinguished, but 36.4% of the sea-stacks are developed in the sheltered areas which wave erosion is more weak than the headland. by this facts we can know well that longshore current occurring in the sheltered areas by wave energy dispersed from the headland have a great effection on the formation and development of the sea-stacks. 3. There are three types of the sea-stacks, the he cone type of se-stack is very common while the table-hill type of the sea-stack is rarest. By relations between sea-stack's types and their site, it is characteristic that the cone type is developed in the headland, the castle type in the sheltered area and the table-hill type in the sheltered area and the table-hill type on the shore platform. This distribution is ascribed to the difference of formation process, sel-cliff's altitude and the development of geological structure. 4. Geological structural attitude of rock and bedding-plane attitude have a basic effection on the form and formation of the sea-stacks, especially joint's density, joint's pattern, joint's spacing and joint's direction have a direct influence on the from of the sea-tacks. 5. The most important formation process of he sea-stacks are wave erosion, especially abrasion and quarrying. and such subaerial weathering as frost action, salt weathering and water layer weathering have an indirect influence on the formation and development of the sea-stacks. 6. Wave erosion occured by storm waves have some influence on the development and extinction of the sea-stacks. Like the south coast and the east coast of the Cheju island were the waves are weak, storm waves which occur in summer have some influence on the development, destruction and extinction of the sea-stacks.

내인성 뇌교 혈관의 공급 영역에 따라 단독 뇌교 경색은 전측(내측과 외측), 피개, 외측 뇌교경색의 세가지 유형으로 분류할 수 있고 이들의 임상 양상과 국소 해부학적 상관 관계는 일치하였다. 전측 뇌교경색은 주로 피질 척수로를 손상시켜 상하지의 부전 편마비를 일으키며 반수 이상의 환자(59%)에서 피개 징후와 증상을 동반하였다. 피개경색은 현훈, 의식변화, 안 운동장애, 감각장애 및 뇌신경마비같은 피개 증상과 징후가 나타나며 일부(30%)에서 경미한 운동장애가 동반되었다. 단독뇌교 경색은 주로 기저 동맥의 관통 동맥 폐색에 의해 발생하곡 대혈관 질환이나 심 색전증 또한 단독 뇌교 경색의 원인이 되었다. Background : In a pontine infarction, variable neurologic deficits present because the pons is very complicated organ including cranial nerve nuclei and several fiber tracts. It's the aim of this study to clarify the clinicotopographical correlation of isolated acute pontine infarcts. Methods : We studied 33 patients with acute pontine infarct and classified them into three subtypes on the basis of lesion location on MRI. Clinical features, angiographic findings and risk factors were compared. Results : Twelve patients had a ventromedial pontine infarcts, in which clinical findings included dysarthria (N=12), hemiparesis (N=12) and tegmental signs (N=6). Five patients had a ventrolateral pontine infarcts, in which clinical findings included vertigo (N=3), hemiparesis (N=3) and sensory disturbances (N=2). Fifteen patients had a tegmental infarcts, in which clinical findings were vertigo (N=13), eye movement disorders (N=10) such as abducence palsy; inter-nuclear opthalmoplegia, ocular bobbing, and sensory disturbance (N=4). Emboligenic heart disease (N=3/33 9.1%) and sign-ificant stenosis of vertebro-basilar artery (3/16 18.7%) were observed. Summary: Corresponding to territories of intrinsic pontine vessels, isolated pontine infarcts could be classified into three main syndromes. Isolated pontine infarcts were usually due to thrombosis of per-forating arteries, but large artery stenosis and cardioembolism also could be causes of isolated pontirie infarcts.

위암은 1999~2001년 국내 암발생율 1위로 조기진단이 중요시 된다. 위암의 검사방법 중 하나인 위장 X선 투시검사는 중요성이 높기 때문에 저자 등은 인천지역을 중심으로 종합ㆍ대학병원, 병원, 개인의원급 21대의 X선장치를 선정하여 X선장치의 현황과 투시검사 및 저격촬영시의 검사조건 등을 조사하였다. 또한 검사중 환자표면선량을 전리조를 이용하여 측정하였다. 본 연구는 위장 X선 투시검사의 실태 및 환자표면선량의 정도를 파악하여 그 현황을 알리고자 실시하였다. This study examined present conditions of upper-gastrointestinal X-ray fluoroscopy and patient skin dose. The authors elected 21 equipments to check the X-ray equipment and exposure factor of fluoroscopy & spot exposure in university hospitals, hospitals, and clinics where perform upper-gastrointestinal X-ray fluoroscopy more than five times every day in Incheon areas. The amount of patient"s skin dose during upper-gastrointestinal X-ray fluoroscopy was measured by ionization chamber.

N/A Hyperprolactinmia is a relatively common clinical problem occurring in more than 25 percent of women who have secondary amenorrhea. Previous studies of hyperprolactinomic women suggested an association with decreased cortical bone density. To determine whether hyperprolactinemia is associated with reduced bone mineral density, we measured the bone mineral density of the vertebrae, femoral neck, and Ward's Triangle by dual photon absorptiometry in 18 hyper-prolactinemic patients, The bone mineral density for each patient fell almost within ±2 standard deviations of the mean for the decade-matched normal subjects. The prevalence of osteoporosis was 28% in hyperprolactinemic patients. The mean duration of amenorrhea in patients with osteoporosis was significantly longer than that in patients without oseteoprosis, 10±5 year, 5±6year, respectively (p<0.05). The mean estradiol level was not significatly different between the oteoporotic and nonoteoporotic groups. There was no significant difference in the pitutiary reserve function between the osteoporotic and non-oseoportoic groups, In patients who under- went surgery, radiotherapy and treatment with bromocryptine, the bone mineral density was relatively lower than that of patients treated by surgery and bromocryptine, or bromocryptine only. It is concluded that hyperprolactinemia is associated with reduced bone mioeral density, which is inversely related to the mean duration of amenorrhea.
