목적:발작의 분류는 발작의 원인, 예후를 추정하거나 항경련제를 선택하는 데 있어 매우 중요하며 뇌파검사는 발작의 종류를 구분하고 적절한 치료를 하기 위해 시행하는 중요한 검사이다. 저자들은 소아에서 임상적 발작이 확실한 경우 간질발작의 임상양상과 뇌파검사 간의 일치 정도를 알아보고자 한다. 방법:2000년 1월 1일부터 2008년 9월 30일까지 1회 이상의 간질발작을 주소로 가천의대 길병원 소아청소년과에 방문한 환자 중 본원에서 처음으로 뇌파검사를 시행한 환자를 대상으로 하였다. 발작의 임상양상은 목격자와 본인의 설명을 기록한 의무기록지를 기준으로 하여 부분발작과 전신발작으로 분류하였고 뇌파검사는 발작간간질양방전을 기준으로 정상과 비정상으로 분류하였으며 각성과 수면상태 모두에서 시행하였다. 결과:총 461명의 환자의 뇌파검사 시의 평균 연령은 6.7세였고 남자는 247명, 여자는 214명이었다. 전체 환자에서 발작의 임상양상은 부분발작이 310명, 전신발작이 187명이었다. 각성뇌파검사에서 비정상은 158명으로 부분발작파가 118명, 전신발작파가 59명, 두 가지 발작파가 한 환자에서 나온 경우가 19명이었고, 수면뇌파검사에서는 비정상이 239명으로 부분발작파가 196명, 전신발작파가 77명, 두 가지 발작파가 한 환자에서 나온 경우가 34명이었으며 전체 환자에서는 비정상이 273명으로 부분발작파가 216명, 전신발작파가 97명, 두 가지 발작파가 한 환자에서 나온 경우가 40명이었다. 간질증후군은 전체 환자 중 90명에서 관찰되었다. 146명(41.5%)의 부분발작과 44명(23.4%)의 전신발작 및 79명(87.8 %)의 간질증후군이 뇌파소견과 일치하였다. 결론:영유아 및 소아에 있어 발작을 진단할 때에는 발작양상 분 아니라 정확한 뇌파소견을 세심하게 고려하여야 한다. Purpose:Electroencephalography(EEG) is an essential method carried out for classifying seizures and taking appropriate treatment. The aim of this study is to investigate the concordance between clinical findings of epileptic seizures and EEG in children. Methods:We enrolled 461 patients from those who visited Gil hospital from January 1, 2000 to September 30, 2008 with the chief complaint of epileptic seizure more than once and checked their first EEG at the same hospital. The clinical findings of seizure were based on the charts and interictal waking and sleep EEGs were done. Results:The mean age of the patients was 6.7 years old. 497 epileptic seizures occurred and its clinical finding included 310 of partial seizures and 187 of generalized seizures. In 315 waking EEG 158 were abnormal including 118 of partial seizures, 59 of generalized seizures and 19 of both seizures, in 431 sleep EEG 239 were abnormal including 196 of partial seizures, 77 of generalized seizures and 34 of both seizures, and in waking and/or sleep EEG 273 were abnormal including 216 of partial seizures, 97 of generalized seizures and 40 of both seizures. Epileptic syndromes were observed in 90 patients. 146(41.5%) of partial seizures, 44(23.4%) of generalized seizures, and 79(87.8%) of epileptic syndromes accorded with EEG. Conclusion:When diagnosing seizures in children, we must consider not only clinical findings but also accurate EEG findings.

In this paper, a high-speed, high-precision chip mount system by using DOS rather than a real-time OS is designed and implemented. A monitoring feedback loop to reduce positional errors in this chip mount system is applied, which can reduce some errors due to disturbances as well as truncation errors. Existing chip mount systems will be compared with the designed and implemented chip mount system.

The purpose of this study is to analyze and grasp the actual lumbaginous condition and relevant factors of 1,182 beauty artists of beauty shops in 5 metropolitan cities, small-to-medium cities, and fishing or agrarian villages for 3 months from June 20 to September 25, 2000 through questionnaires. 1) They showed 61.0 percents in her twenties, 66.4 percents of unmarried women from all the female objects, 70 percents in high school graduates as educational background, 52.4 percents in metropolitan city as service place, 25.4 percents in smoking rate, 71.6 percents in drinking rate, 48.1 percents in general bed as condition of bedroom, 17.9 percents in exercising rate, 53.6 percents in 'little eating', 39.6 percents in two or three centimeters of heel, and 89.5 percents in hair as beauty-related professional field. 2) The rate of lumgaginous experience of beauty artists was 83.5 percents. They showed higher rate of 91 percents in the thirties and forties, 92 percents of the married, 93.9 percents in junior college graduates, 97.2 percents in higher economic classes, 88.7 percents in smokers, 85 percents in general bed, 89.3 percents in sleeping on one's face, 85 percents in swimming, 92 percents in stretch, 86.7 percents in 56 to 60 kilograms of weight, 89.7 percents in group O blood, 90.5 percents in experienced women of abortion, 97 percents in heel over 8 centimeters, 58.3 percents in 'feel much fatigue', 93.6 percents in inconvenient chair of beauty shop, and 89.4 percents in a lack of recess than other group. 3) The more women who have been experienced in lumbago, the higher their social treatment(p<0.01), income(p<0.001), working time(p<0.05), job potentiality(p<0.05), inner affinity(p<0.05), and job satisfaction of environment(p<0.001) were. Women who suffered much stress related to job environment(p<0.001), client(p<0.01), and their duty(p<0.01) showed high rate of lumbaginous experience. 4) In degree of lumbago by characteristic, there was the significant difference in age over 50-years-old, unmarried women, college graduates, service of small-medium cities, higher economic classes, smokers or drinkers, hot-floored room, sleeping with ransack, stretch or swimming, group A blood, fat body, experience of abortion, 6 to 7 centimeters of heel, convenient chair of beauty shop, insufficient recess, lumbago continued for one to the three months in comparison of other group. 5) There were variables of posture such as to place materials under one foot(p<0.001), to lay arm on armrest and desk(p<0.001), to pull materials near body while lifting them (p<0.05), to sometimes use anodyne(p<0.01), not to lift also light materials(p<0.001), to be inconvenient in sleeping(p<0.001), to be absent at job for two or three days(p<0.01). The degree of depression(p<0.001), had the significant effect on the degree of lumbago(32.7%). The results are as follows : Beauty artists have faced upon dangerous job environment to cause lumbago. The more the industrial society will be developed, the more their burden of service will be increased. In addition, the occupational stress and posture of beauty artists who showed high job satisfaction and high economical level became major factors which have had an effect on their lumbago. In conclusion, it is desirable for beauty-related organizations and professionals to positively develop program of health education with much concern as well as to lessen stress of beauty artists through education of job posture and rightful life in order to prevent lumbago of those beaut.

본 논문에서는 실시간으로 상수 및 변수의 병렬 매칭이 가능한 새로운 구조의 하드웨어 기반 룰-베이스 시스템 구조를 제안한다. 이 시스템은 context-aware computing 시스템에서 상황 인식을 위한 기법으로 적용될 수 있다. 제안한 구조는 기존의 하드웨어 기반의 구조가 가지는 룰의 표현 및 룰의 구성에서 발생하는 제약을 상당히 감소시킬 수 있다. 이를 위해 변형된 형태의 content addressable memory(CAM)와 crossbar switch network(CSN)가 사용되었다. 변형된 형태의 CAM으로 구성된 지식-베이스는 동적으로 데이터의 추가 및 삭제가 가능하다. 또한 CSN은 input buffer와 working memory(WM) 사이에 위치하여, 시스템 외부 및 내부에서 동적으로 생성되거나, 시스템의 설정에 의해 지정된 데이터들의 조합 및 pre-processing module(PPM)을 이용한 연산을 통하여 WM을 구성하는 데이터를 생성시킨다. 이 하드웨어 룰-베이스 시스템은 SystemC ver. 2.0을 이용하여 설계되었으며 시뮬레이션을 통하여 그 동작을 확인 및 검증하였다. Context-aware computing systems require real-time context reasoning process for context awareness. Context reasoning can be done by comparing input information from sensors with knowledge-base within system. This method is identical with it of rule-based systems. In this paper, we propose hardware rule-based system architecture which can process context reasoning in real-time. Compared to previous architecture, hardware rule-based system architecture can reduce the number of constraints on rule representations and combinations of condition terms in rules. The modified content addressable memory, crossbar switch network and pre-processing module are used for reducing constraints. Using SystemC for description can provide easy modification of system configuration later.

USP47 and C Terminus of Hsp70-Interacting Protein (CHIP) Antagonistically Regulate Katanin-p60-Mediated Axonal Growth

<P>Katanin is a heterodimeric enzyme that severs and disassembles microtubules. While the p60 subunit has the enzyme activity, the p80 subunit regulates the p60 activity. The microtubule-severing activity of katanin plays an essential role in axonal growth. However, the mechanisms by which neuronal cells regulate the expression of katanin-p60 remains unknown. Here we showed that USP47 and C terminus of Hsp70-interacting protein (CHIP) antagonistically regulate the stability of katanin-p60 and thereby axonal growth. USP47 was identified as a katanin-p60-specific deubiquitinating enzyme for its stabilization. We also identified CHIP as a ubiquitin E3 ligase that promotes proteasome-mediated degradation of katanin-p60. Moreover, USP47 promoted axonal growth of cultured rat hippocampal neurons, whereas CHIP inhibited it. Significantly, treatment with basic fibroblast growth factor (bFGF), an inducer of axonal growth, increased the levels of USP47 and katanin-p60, but not CHIP. Consistently, bFGF treatment resulted in a marked decrease in the level of ubiquitinated katanin-p60 and thereby in the promotion of axonal growth. On the other hand, the level of USP47, but not CHIP, decreased concurrently with that of katanin-p60 as axons reached their target cells. These results indicate that USP47 plays a crucial role in the control of axonal growth during neuronal development by antagonizing CHIP-mediated katanin-p60 degradation.</P>
