기존 한옥의 계승을 위한 관련 연구가 진행되고 있으나, 한옥 보급에는 실용성을 띄지 못하고 있다. 이는 한옥 시공기술의 복잡성과 자재 생산기술 부족으로 인한 제한적 범위 내에서 공사가 진행됨에 따라 높은 공사비를 원인으로 꼽을 수 있다. 이에 따라 현재 전통 한옥이 가진 정체성을 살리고 현시대에 보급될 수 있는 신 한옥으로의 진화를 위해 부재간의 연관을 분석하고 조립하는 방식을 지식으로 구성하고 디지털 모델링을 함으로써 공사비 절감이 가능케 하는 방법 등이 연구되고 있다. 본 연구에서는 한옥 설계자를 고려한 효율적인 부재 가공 정보 지원을 목표로 한옥 부재 실무 가공 분석을 통해 경제성, 시공성을 파악하고 최적화 방안을 위한 한옥 부재 제작 CNC 시뮬레이션을 통해 효율적인 가공 프로세스의 발전 가능성을 예측하여 최적화된 부재가공 정보를 제안하고 이를 기반으로 한옥 수요자들을 위한 설계지원 방법에 대한 구체적인 방안을 제시함으로써 한옥의 생상성 향상에 기여하고자 한다. There have been a lot of studies about the Han-ok, the Korean-style house, in perspective of the inheritage of existing ones, but there are no practicality in the supply of Han-ok. The cause is considered to exist in the complexity of Han-ok and the techniques required to manufacture its components and in the relatively higher construction expenses in the process which is within restricted range. On the contrary, in order to preserve the identity of traditional Han-ok and encourage the evolution to create a new Han-ok that can be supplied to the present period, there has been studies that analyzes the connection between sub-components and assemble them into a digital model which can possibly decrease the expenses spent on construction. The research`s objective is to provide valuable information for Han-ok designers, which contains methods on manufacturing sub-components effectively. Furthermore, by analyzing the current manufacturing method`s workability and economic feasibility, the research can obtain an optimum alternative for improving Han-ok`s production. Also by using CNC simulation, the possibility of an effective production can be predicted, as well as the information that can lead to the optimum method for an efficient sub-component manufacturing and suggest a specific resolution which can also affect on the improvement of Han-ok productivity.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

In order to evaluate the validity of current screening criteria of lead exposure and to provide effective information for the better health management of lead workers, author investigated the interrelationship between blood lead and blood zinc protoporphyrin(ZPP) and evaluate the validity of blood zinc protoporphyrin as the screening test and blood lead as gold standard of diagnostic test. The total of 2245 lead workers (male workers: 1982, female workers : 263) from 12 lead using industries were studied. Blood lead, ZPP, hemoglobin and hematocrit were selected as lead exposure variables. Personal information on sex, age and work duration were also checked. Blood lead was measured with flameless atomic absorption spectrometry (model: Hitachi 8100) using standard addition method. Blood ZPP was measured with portable hematoflurometer (model: Aviv 206). The results obtained were as follows: 1. The mean blood lead of all lead workers were 0.7±14.3㎍/㎗(Male: 31.0±14.4㎍/㎗, Female: 28.2±12.9㎍/㎗), whereas the mean blood ZPP of those were 68.1±47.5㎍/㎗(Male: 63.9±43.7㎍/㎗, Female: 100.1±61.0㎍/㎗). The mean value of hemoglobin and hematocrit of all lead workers were 14.5±1.5g/㎗(Male: 14.7±1.3g/㎗, Female: 12.3±1.2g/㎗) and 45.4±3.6(Male: 46.2±2.8, Female: 39.5±3.1) respectively. 2. Validity of test using blood zinc protoporphyrin as screening test for blood lead levels of 30㎍/㎗ as gold standard of diagnostic test revealed that the highest validity value for male and female lead workers were 50 and 90 ㎍/㎗ of ZPP respectively, showing 50 and 60 ㎍/㎗ of ZPP for all lead workers. While those test for blood lead levels of 40㎍/㎗ as gold standard of diagnostic test revealed that the highest validity value for male and female lead workers were 60 and 90 ㎍/㎗ of ZPP respectively, showing 60 ㎍/㎗ of ZPP for all lead workers, those test for blood lead levels of 50 and 60㎍/㎗ as gold standard of diagnostic test revealed that the highest validity value for male and female lead workers were 60 or 70 and 100 ㎍/㎗ ZPP respectively, showing 60and 70 or 80 ㎍/㎗ of ZPP for all lead workers. 3. Predictive value of test using blood zinc protoporphyrin as the screening test for different blood lead levels of 30, 40, 50 and 60㎍/㎗ as gold standard of diagnostic test revealed that positive predictive value of screening test were decreased by the increase of blood lead level regardless of csreening criteria value ZPP and negative predictive value of screening test were increased accordingly regardless of screening criteria value of ZPP. On the other hand, within same blood lead level as a gold standard positive predictive values were inceased by the increase of screening criteria value of ZPP, whereas the negative predictive value were decreased accordingly by the the increase of screening criteria value of ZPP. 4. The correlation analysis of all lead workers among study variables revealed that CPbB and natural log transformation ZPP(LZPP) were better correlated with other variables and found to be better estimate than PbB and ZPP themselves. The age was correlated with all other variables, but the work duration was not. The correlation analysis of male and female workers among study variables revealed the same results with all lead workers. 5. The slope of simple linear regression of CPbB (independent variable) with ZPP in female workers(3.223)was steeper than in male workers(2.144). That of lead workers with work duration of less than 1 year was steeper than that of lead workers whose work duration was more than 1 year. But there was no slope difference between two groups divided by their work duration of 2 years less and more. The slope of simple linear regression of CPbB lead (independent variable)with ZPP in lead workers whose blood lead were higher than 30㎍/㎗and 40㎍/㎗ were steeper than those whose blood lead were less than 30㎍/㎗ and 40㎍/㎗. 6. The slope of simple linear regression of CPbB (independent variable) with ZPP in lead industries with low mean blood lead were less steeper than those with high mean blood lead. 7. The slope of simple linear regression of CPbB (independent variable) with LZPP in female workers(0.0308was steeper than in male workers(0.0253). That of lead workers with work duration of less than 1 year was steeper than that of lead workers whose work duration was more than 1 year. But where was no slope difference between two groups divided by their work duration of 2 years less and more. While the slope of simple linear regression of CPbB lead (independent variable) with LZPP in lead workers whose blood lead were hogher than 30㎍/㎗ was not steeper than those whose blood lead were less than 30㎍/㎗, there was no slope difference between two groups whose blood lead were less than 40㎍/㎗ and more than 40㎍/㎗. 8. The slope of simple linear regression of CPbB (independent variable) with LZPP in lead industries with low mean blood lead were less steeper than those with high mean blood lead, but the difference was not significant then that of CPbB and ZPP. With above results, it is recommended that the screening criteria value of ZPP should be down to 60-70㎍/㎗ from 100㎍/㎗ for male lead workers and screening criteria of ZPP for female lead workers was all right with current value of 100㎍/㎗. So it is recommended to make different screening criteria of ZPP for male and female workers like the hemoglobin and hematocrit screening criteria. It is also preferable to use CPbB and LZPP rather than uncorrected PbB and ZPP in the evaluation of lead exposure for lead workers.

설한국,이상구,Seol, Han-Guk,Lee, Sang-Gu 한국수학사학회 2009 Journal for history of mathematics Vol.22 No.3

본 논문은 한국수학사에서 연구와 정리가 취약한 시기인 근대수학의 도입기를 조사하면서, 그 근대수학의 도입기에서 만나게 되는 인물인 이상설(李相卨)에 대한 조명을 시도한다. 시대적 상황이 모든 분야의 침체기를 가져온 구한말 이상설은 근대수학에서 당대를 대표하는 높은 학식을 쌓고 뛰어난 재능을 보여주었다. 그간 이상설에 대해 '근대수학교육의 아버지'라는 평가가 없지 않았음에도 불구하고 낯설게 느껴진다면, 그것은 그가 독립운동가로만 강하게 각인된 탓일 것이다. 하지만 그는 19세기말 조선 근대수학의 첫 번째 교과서 편저자이자 수학교사이기도 했음을 새겨둘 필요가 있다. 대유학자이면서도 선구적으로 외국어와 서양과학 특히 근대 서양수학을 이해한 면모는 한국이 배출한 천재 중 하나라는 평가가 결코 과장이 아님을 보여준다. 이에 본 논문에서는 한국 근대수학교육에 커다란 기여를 한 인물인 이상설의 교육과 학문 및 실천업적을 조명한다. 보재 이상설이 1886년경에 쓴 책 <수리>와 최초로 수학과 과학을 관립교육기관의 교육과정에 편성한 과정, 최초의 근대수학교과서로 여겨지는 <산술신서>의 발간, 민족교육기관인 '서전서숙'의 설립 및 운영을 포함한 보재의 업적을 한국수학사 관점에서 조명한다. 또한 <산술신서>의 목차와 구체적인 내용 및 1901년에 출간된 <신정산술>의 내용을 소개하고, 지금까지 부정확하게 알려진 <수리>와 <산술신서>에 관한 몇 가지 역사적 사실을 발굴하여 재조명한다. Most who have heard of Sang-Seol Lee know him for his contribution to the Korean independence movement nearly a hundred years ago. This paper, however, will discuss Lee's other great contribution to his country; that of being "The father of modern mathematical education in Korea". Lee passed the rigorous government officer examination with the highest honor and became a teacher for the royal prince. Later he became the president of Sunkyunkwan, a national institute of higher learning since 1398, and eventually a well-known university bearing the same name. Lee was also a highly regarded Confucian scholar and well versed in foreign languages. He wanted Korea to become a modern country and felt that the areas of science and engineering were studies that needed improving in order to achieve modernization. While researching Western textbooks on the subjects he realized that Western mathematics would be especially important for Korea. With that, it became his mission to integrate Western mathematics into the Korean educational system. This paper will explain the importance of Sang-Seol Lee's contributions to mathematic education in Korea and how it helped Korea become the modern nation it is today.

The ratio of A/C% in Fe was 25.1~64.3% and lower than that in Ca and protein in general.

2자유도 PI 제어기를 이용한 BLDC 전동기의 벡터제어에 관한 연구

이종현,성낙규,이상집,이승환,오봉환,이훈구,한경희 명지대학교 산업기술연구소 2001 産業技術硏究所論文集 Vol.20 No.-

This paper describes the speed control method of BLDC Motor using TDOF PI ( Tow-degree of freedom PI ). PI control method generally used has difficulty in efficient speed control because speed response and load torque response interfere each other. It can't decrease the overshoot of motor speed w rm, and shorten the response time of load torque TL, at the same time according to the step alternation of speed reference w rm. Therefore TDOF PI is applied to BLDC Motor in order to supply these weak points of PI control method in this paper. TDOF PI can get the torque characteristic of short response time as well as stable and prompt speed adjustment by separate control for speed response and load torque response. The results from the tests of C program simulation and system construction show that TDOF PI is superior to PI control system in speed adjustment and load torque response.

Background : Nontyphoid Salmonella (NTS) is a leading cause of human food-borne enteritis, It has been known that integron, a naturally occurring gene capture and expression element, Plays an important role in the development and dissemination of multidrug-resistance. In this study, we investigated the prevalences and molecular characteristics of integrons in NTS clinical strains. Materials and Methods : Between 1995-96 and 2000-03, a total 261 NTS clinical strains comprising 39 serotypes were collected from clinical specimens. All strains were serotyped, and the MICs of ampicillin, chloramphenicol, streptomycin, sulfamethoxazole, tetracycline, and trimethoprim were determined by agar dilution method. Integrons were detected by PCR amplification of integrase genes, and gene cassettes were determined by PCR and sequencing, Conjugation experiments were performed using E. coli J53 as a recipient. The clonal relationship was analyzed by pulsed-field gel electrophoresls (PFGE). Results : Of the 261 strains tested, class 1 integrons were present in 21 strains (8.0%). Class 2 and class 3 integrons were not found. The integron-positive rate was higher in S. Typhimurium (24.2% [8/33]) than in S. Enteritidis (2.0% [3/153]). Overall rates of antimicrobial resistance were higher in integron-positive strains. dhfr12-orfF-aadA2gene cassette was detected in 5 strains, aadA2in 4 strains, dhfr17-orfF-aadA5 in 2 strains, and addA1 in 1 strain. Ten integron-positive transconjugants were successfully selected. Among 8 integron-positive strains of S. Typhimurium, 7 had similar PFGE patterns. Conclusion: This study suggests that integrons are already playing a significant role in antimicrobial resistance in NTS. Continuous monitoring is needed to detect the emergence and spread of integron-mediated antimicrobial resistance.

Three different treatments for induction of estrus in Korean native black goats were compared: follicle stimulating hormone(FSH, FSH-p^TM), FSH combined with MAP(intravaginal impregnated sponges, Veramix^ⓡ, containing 60 ㎎ medroxy progesterone acetate for 14 days), and FSH combined with progesterone(Ovaron^ⓡ, 10 ㎎ IM for 10 days) and PGF_2α(Lutalyse^ⓡ, 3 ㎎ IM at first FSH injection). FSH for inducing estrus and superovulation was given a total 20 ㎎ intramuscularilly in decreasing dosage injections twice daily over 4 days. The MAPs were withdrawn at the 3rd day of FSH injection. Estrus observations were conducted every 6 hours from last FSH injection for 24 hours by placing the does with fertile male goats. Estrus and superovulation were more successfully induced with treatment of MAP + FSH than other treatments(FSH only, or progesterone + PGF_2α + FSH) (estrus induction; 100 vs 42.8 and 71.4%, ovulation points; 11.4 vs 5.4 and 4.4, respectively). The effect of gonadotropin releasing hormone(GnRH) on the ovulation rate was also examined. However, no difference was observed for inducing ovulation with treatment or dosage(100 ㎍ 200 ㎍) of GnRH. Low midline laparotomies were performed, and then ovarian responses (ovulations and follicular development) were examined by exteriorization of the reproductive tracts. Ova were recovered from oviducts by retrograde flushing 60-146 hours after MAP removal, and were classified the developmental stages. Overall 66.1% (236/357) of recovery rate was obtained from 30 superovulated does. The optimal recovery time of microinjectable 1-cell zygotes was approximately 72-76 hours after MAP removal.
