자기공명영상을 이용한 한국 성인의 엉치뼈틈새와 척수원뿔 사이 거리 연구
박태수(Tai Soo Park),황병욱(Byeong-Wook Hwang),박상준(Sang-Joon Park),백선용(Sun-Yong Baek),윤식(Sik Yoon) 대한체질인류학회 2016 해부·생물인류학 (Anat Biol Anthropol) Vol.29 No.4
이 연구에서는 경막바깥신경성형술 시행에 있어서 중요한 엉치뼈틈새에서 경막주머니종말부 및 척수원뿔 사이의 거리를 자기공명영상에서 계측하여 한국인의 생체 연구에 대한 기초 자료를 제공하고자 한다. 허리통증으로 자기공명영상을 촬영한 환자 중 척추압박골절이나 척추전방전위증 그리고 기형 등이 없는 환자 200명 (남자 88명, 여자 112명)을 대상으로 하였으며, 평균 연령은 54.3세 (20~84세), 평균 신장은 161.3 cm (135~187 cm)이었다. T2강조 자기공명영상을 이용하여 엉치뼈틈새에서 경막주머니종말부 그리고 척수원뿔 사이 거리를 계측하여 성별 및 신장에 따른 상관관계를 분석하였다. 엉치뼈틈새꼭지에서 경막주머니종말부까지 거리는 62.8±9.4 mm, 엉치뼈틈새꼭지에서 척수원뿔까지 거리는 232.2±21.8 mm, 엉치뼈틈새꼭지에서 경막주머니종말부 사이 최소 거리는 34.8 mm, 최대 거리는 93.9 mm, 엉치뼈틈새꼭지에서 척수원뿔 사이 최소 거리는 155.0 mm, 최대 거리는 284.0 mm이었다. 엉치뼈틈새꼭지에서 경막주머니종말부까지, 그리고 엉치뼈틈새꼭지에서 척수원뿔까지 거리는 모두 여성이 남성보다 짧게 나타났고 (p<0.05), 엉치뼈틈새꼭지에서 경막 종말부 및 척수원뿔 사이 거리는 신장에 대해 유의한 상관관계를 보였다(p<0.01). 이 연구의 결과는 한국 성인의 엉치뼈틈새에서 경막주머니종말부 및 척수원뿔 사이 거리에 대한 생체 계측 자료를 제공하며, 경막바깥공간에 대한 임상적 시술의 안전성 확보와 한국인의 체형에 맞는 카테터 개발에 도움이 될 것이라 생각한다. The purpose of this study was to provide basic biometric data on Korean adults through magnetic resonance imaging (MRI)-based measurements of the distances between the apex of sacral hiatus (SH) and the termination of dural sac (DS), and between SH and conus medullaris (CM) because they are critical to the performance of epidural neuroplasty. A total of 200 patients (88 males and 112 females) with back pain, who had no spine fracture, significant spinal deformity, and spondyloisthesis were selected for this study. The subjects were of mean age 54.3 (20~84) years and mean height 161.3 cm (135~187). T2-weighted MRI images were used for correlation analysis to evaluate the relationships between the distances, and variables such as sex and height. In all patients, the mean distance between SH and DS was 62.8±9.4 mm and the mean distance between SH and CM was 232.2±21.8 mm. The minimum distance and the maximum distance between SH and DS were 34.8 mm and 93.9 mm respectively, and the minimum distance and the maximum distance between SH and CM were 155.0 mm and 284.0 mm respectively. In female patients, both the distances between the SH and DS, and between SH and CM were shorter when compared to those of the male patients (p<0.05). Both the distances between SH and DS and between SH and CM showed a significant correlation with height (p<0.01). The results of this study will provide a useful biometric data on the distances between SH and DS and between SH and CM in Korean in ensuring clinical safety and in the development of more effective catheterization techniques for epidural neuroplasty in Korean.

원외부 후하소뇌 대 동맥류의 수술적 제거 : 증례보고 Case Report
황병욱,오남훈,유수일,김진만,황달성,하인선,이용성 대한신경외과학회 1995 Journal of Korean neurosurgical society Vol.24 No.12
The authors report a rare case of right distal posterior inferior cerebellar artery(PICA) aneurysm arising from just distal to its vermian branch. A 36-year-old female patient presented with a sudden onset of headache, nausea, dizziness and ataxia without any other neurologic deficit. On brain computerized tomographic(CT) scan and magnetic resonance imaging(MRI), a well-defined round mass was detected just behind the fourth ventricle. On transfemoral vertebral angiogram(TFVAG), it was confirmed as a saccular aneurysm arising from the vermian branch of the right PICA. The aneurysm was initially directly clipped through bilateral suboccipital approach. Postoperative follow up angiogram after two weeks revealed a more enlarged aneurysm and an incompletely clipped neck. After making sufficient exposure of the aneurysm, the neck was reclipped and the sac removed. Postoperative results were uneventful.

There is no doubt that mathematics in past was introduced into schools as a simple tool of application to natural science, but the application part of mathematics at present is extended not only to the fields of technical science but to those of finance, industry, culture, information, and behaviour science. So, since 1957, the movement of modernization of mathmatics has been displayed in the school to reform the method of teaching mathematics, and the essential education of mathematics by logic began to -be acomplished. Logic is a kind of the science of reasoning. Reasoning is a special kind of thinking, in which inference takes place or in which other new facts (called the conclusion) are drawn from some known facts (called the premise). Inference is either immediate or mediate. In the mediate inference, there are two kinds of inference, that is, deduction and induction. Also, commonly we mean it as deduction, which is expressed by the syllogism. In primary schools, it is a certain fact that inductive inference may be better than the other only for the learning by discovery, but the new facts got by inductive method can not be used again to the-other place in learning, if the mathematical logic for the new facts was not understood again by deductive method. Because it has a logical exactitude, teachers in primary school have feared to teach pupils by deductive method in solving problems. But, in general aims of arithmetic in primary schools, there is a requirement to grow an ability and an attitude to consider logicaly, and it is our common view that there remain many important things beyond the teaching by deductive inference in primary school too. So, we examined the tendency in logical thinking of them and the grade of understanding for logical language in problems from the pupils in the school 3rd, 4th, 5th, and 6th grades in a few primary schools and have found the fact that the teaching of logical language must be preceded from the low grade before the teaching of deductive inference. Therefore, according to the examined results, at first, we explorately established the aims and contents for the teaching of logical language. And the next, the aims and contents for the teaching of deductive inference in respect to fundamental four types, that is, categorical sylloism (q→p, p├q), negative syllogism (p→q,∼q├∼p), hypothetical syllogism (p→q, q→r├p→r), and disjunctive syllogism (p∨q,∼p├q).

The authors have experiend a case of histiocytosis-X A 7-arsdd male patient had three tender masses, one on the right parietal region, another on the left parietal region, the other on the left Occipital region and revealed exophthalmus on his left side. Plain skull films showed multiple punched out skull defects and on lumbar spine films, collapse of body of second lumbar vertebra was detected. Among the masses, the largest right parietal one was excised totally. The find diagnosis revealed histiocytosis-X on pathologic basis and he was given subsequent chemotheraphy.
