본 연구는 Kolb의 4가지 학습유형에 따라 초등학교 수학영재, 과학영재, 일반 학생의 학습유형을 비교해 보고, 학습유형에 따라 교수방법 선호도가 어떻게 달라지는지 확인하기 위한 것이다. 이를 위해 지역교육청 2곳의 영재교육원 초등학교 수학ㆍ과학영재 학생 각60명, 일반 학생은 초등학교 2곳의 6학년 120명 총 240명을 연구 대상으로 하였으며, 이들의 학습유형검사ㆍ교수방법선호도 검사의 자료를 수집ㆍ분석하였다. 검사도구로는 Kolb(1999)의 학습유형검사(LSI), Renzulli, Rizza, & Smith(2002)의 교수방법 선호도 측정 검사지를 활용하였다. 본 연구의 결과 수학영재 학생과 과학영재학생의 학습유형은 차이가 없었으나 영재학생과 일반학생의 학습유형에는 차이가 있었으며, 동화적 학습자 유형을 제외한 발산적 학습자, 수렴적 학습자, 조절적 학습자 유형은 고유하게 선호하는 교수방법들을 가지고 있었다. 또한 수학영재 학생과 일반학생은 학습유형에 따른 교수방법 선호도에 차이가 없었으나, 과학영재 학생은 학습유형에 따fms 교수방법 선호도가 다르게 나타났다. 이런 결과는 영재학생과 일반학생의 학습유형이 서로 다르고 그에 따른 교수방법도 다르다는 것을 나타낸다. 따라서 교실수업을 담당하는 교사들은 학생들의 학습유형에 맞는 교수방법을 제공하여 교수적합성을 달성함과 동시에 교수 효과를 극대화하기 위해서 각각의 학습유형과 교수방법에 대한 충분한 이해가 선행되어야 할 것이다. The purpose of this study is to compare the learning styles of the mathematics gifted, the science gifted, and general students at elementary schools by Kolb"s four learning styles, and ascertain how the preference of instructional methods become different by learning style. To achieve the purpose in this study, the four propositions were set as follows: First, what differences exist among the mathematics gifted, the science gifted and general students in terms of learning style? Second, what differences exist in terms of the preference of instructional methods by learning style among the mathematics gifted, the science gifted, and general students? To solve the abovementioned propositions, this study targeted 60 elementary school-level mathematics gifted students, 60 science gifted students at gifted students education institutes, and 120 six graders at Elementary School: this study targeted a total of 240 students. For the learning style test used in this study, ""Learning Style Inventory (LSI),"" which originally presented by Kolb in 1976, but was revised anew in 1999, and was translated by Lee, Shin-dong (2005), was used. As a test to measure the preference of instructional methods, ""Measure of Student Preference for Instructional Techniques,"" developed by Renzulli, Rizza, and Smith (2002), and translated by Lee Shin-dong (2005) was used. The confidence levels of the tests were good, respectively. The analysis of the collected test responses was tested through a confidence analysis, technical statistics, MANOVA, and Sheffe test was used for follow up test. The SPSS 12.0 Program was used for the analysis. The analytical results of the collected data are presented as follows: Firstly, there was no difference in the learning style of the mathematics gifted and the science gifted, but there was difference in the learning style of the gifted and general students. Secondly, it was identified that divergent learners, convergent learners, regulated learners, except for assimilative learners, had their preferred instructional methods. Thirdly, there was no difference in the preference of instructional methods by learning style and gender between the mathematics gifted and general students. The science gifted students had different preference of instructional methods by learning style, but they did not show any difference on the preference of instructional methods by gender. In conclusion, the divergent learners and convergent learners are judged to be more active in learning activities and have higher learning motivation. Teachers taking charge of classroom teaching should provide instructional methods in line with such learning styles so as to achieve the adequacy of instruction, and draw maximum instructional effects. Those teachers also need to pay more attention to enhancing learning motivation of the relatively passive regulated learners and assimilative learners.

송진수,최평균,송경호,조재현,김성한,방지환,이창섭,박경화,박경운,신수,최희정,김의석,김동민,이미숙,박완범,김남중,오명돈,김의종,김홍빈,최강원 대한감염학회 2006 감염과 화학요법 Vol.38 No.6

목적 : 최근 전세계적으로 지역사회획득 메티실린내성 황색포도알균(community-associated methicillin-resistant Staphylococcus aureus, CA-MRSA)의 보고가 증가하고 있다. 하지만, 우리나라에서는 CA-MRSA 감염증에 대한 증례보고만 있을 뿐 아직까지 체계적인 연구결과가 없는 실정이다. 저자들은 국내에서 CA-MRSA의 빈도, 감염증의 임상적 양상, 분리된 균주의 항균제내성 양상을 조사하였다. 재료 및 방법 : 2005년 1월부터 2005년 6월까지 7개 병원에서 MRSA가 분리된 환자의 명단을 파악한 후 의무기록지와 건강보험심사평가원의 자료를 검토하였다. 외래나 응급실에서 혹은 입원 후 72시간 이내에 균주가 분리되고 MRSA 획득과 관련된 위험인자가 없는 경우 CA-MRSA로 정의하였으며, 분리된 균주의 임상적 의미에 따라 원인병원체(pathogen), 집락화(colonizer), 미결정(undetermined)으로 분류하였다. Penicillin과 oxacillin을 제외하고 3개 이상의 다른 계열 항균제에 내성이면 다제내성으로 정의하였다. 결과 : 연구기간동안 총 3,251주의 황색포도알균이 분리되었으며, 이 중 MRSA는 1,900주(58.4%)였다. MRSA 가운데 CA-MRSA는 114주(6.0%) 였으며, 이들이 분리된 부위는 귀(62주), 비뇨기계(14주), 피부 및 연부조직(11주), 호흡기계(10주), 혈액(3주) 등이었다. CA-MRSA 균주 가운데 집락균은 22주, 원인병원체는 22주였으며, 나머지 균주에 대해서는 그 임상적 의미를 결정할 수 없었다. 항균제 감수성 검사를 시행한 73균주 중 47주(64.4%)는 다제내성이었다. CA-MRSA 감염증 22예 중 피부 및 연부조직 감염(9예)과 중이염/외이도염(9예)이 가장 흔하였다. 침습적 감염증(invasive infection)은 4명(원발성 균혈증 3예, 감염성 관절염 1예)에서 확인되었지만, CA-MRSA 감염증으로 사망한 환자는 없었다. 결론 : 병원내 감염증에서는 MRSA가 심각한 문제이지만, 아직까지 지역사회 감염증에서 CA-MRSA는 흔하지 않았다. Background : Methicillin-resistant Staphylococcus aureus (MRSA) infection has emerged in patients who do not have the established risk factors. In Korea, little is known about the epidemiology and clinical features of community-associated MRSA (CA-MRSA). Material and Methods : Clinical microbiology laboratory databases of 7 hospitals were reviewed to identify the patients from whom MRSA was isolated during the period of January to July 2005. Only one isolate per patient was enrolled. In order to identify the risk factors of MRSA acquisition, the medical records and the Health Insurance Review Agency databases were reviewed. CA-MRSA was defined as MRSA isolated from patient without established risk factors. We analyzed patient demographics, underlying medical conditions, characteristics of infection, and antimicrobial susceptibility profiles. Results : Of total 3,251 S. aureus isolates, 1900 (58.4%) were MRSAs. Of the MRSA isolates, 114 (6.0%) were CA-MRSA. Of 114 CA-MRSA isolates, 22 (19.3%) were colonizers, 22 (19.3%) were pathogens, and the clinical significance of remaining 70 (61.4%) could not be determined. Median age of the 22 patients with CA-MRSA disease was 47 years. Nine patients had skin and soft tissue infections, 9 ear infections, 3 bacteremia, 1 septic arthritis. Seven patients had underlying medical disease. None died of the CA-MRSA infections. Of the 73 isolates of CA-MRSA, 47 (64.4%) were resistant to more than 3 classes of antibiotics besides β-lactams. Conclusion : Although MRSA is highly prevalent among hospital-associated S. aureus infection, CA-MRSA infections are not common.

Traditional houses as cultural assets are required to preserve their original forms, which could conflict with residents' demand for higher living standards. These houses were built with sustainable structure and material that can contribute to natural environmental control of building. Nevertheless, their thermal environment seem to be inferior in modern living standards and improvements are certainly necessary. The aim of the study is to evaluate the effects of the building improvements on the energy performances of a traditional house. In this study, the simulation program of Visual DOE 3.1 was used to predict annual heating and cooling energy loads of the house, and sensitivity studies were performed. The subject building in this study was a main building of Genjaegotaek, located at Oeam-maeul, Asan, Chung-Nam. The simulation results for that building indicated that the main determinants of the building energy loads were walls and openings(windows and doors): They represented about 50% and 41% of the annual heating loads, and 49% and 24% to the annual cooling loads, respectively. The improvements of wall and openings turned to be more effective in the house. Of the three measures of energy improvements, wall insulation is the most relatively important, followed by openings, and then ceiling insulation. The energy simulation was further performed with all three improvement measures, and the results indicated that the building heating and cooling loads decreased about 66% and 13%, respectively, and the total annual energy loads decreased by about 46%. This study addressed the issue of thermal improvements of traditional house through building energy simulations. Due to some unknown properties of building elements there are some limitations in modeling the traditional house, and more detailed information from surveys and experiments is needed for more reliable thermal modeling.

김의종,오명돈,박기호,신형식,이환종,김남중,최강원 대한감염학회 1996 감염 Vol.28 No.4

목 적 : 인형거대세포바이러스(HCMV)는 면역 저하 환자에서 폐렴, 망막염, 간염 등 치명적인 감염증의 원인이다. 전통적인 세포 배양법으로 HCMV를 분리하기까지는 1주에서 4주가 걸리므로 이 바이러스에 의한 질환이 의심되는 경우 신속한 진단법을 이용한 진단이 바람직하다. 저자들은 한국에서 분리되는 야생주 HCMV를 검출하는데 중합효소 연쇄 반응법을 이용할 경우의 진단적 유용성을 알기 위하여, 전통적인 세포배양법으로 HCMV가 분리된 검체를 이용하여 중합효소 연쇄 반응법의 특이도와 민감도를 평가하였다. 방 법 : 국내 야생주 HCMV 15주, 그리고 전통적인 바이러스 배양법으로 HCMV가 분리된 소변 15검체를 대상으로 중합효소 연쇄 반응을 실시하였다. 중합효소 연쇄 반응은 Towne주의 immediate early antigen의 유전자에서 유리된 primer MIE와 AD169주의 immediate early antigen의 유전자에서 유리된 primer IE를 이용하였다. 증폭 산물은 겔 전기영동 후 EtBR으로 염색하여 자외선 하에서 관찰하였다. Primer IE에 의한 증폭산물은 또한, DNA blot hybridization 방법으로 확인하였다. 결 과 : 1) 국내 HCMV 야생주 15주를 대상으로 중합효소 연쇄 반응을 한 결과 primer IE를 이용한 경우에는 100%(15/15)에서 177bp의 증폭 산물이 관찰되었고, 이들 증폭 산물은 모두 probe IE와 보합 결합되었다. primer MIE를 이용한 경우에는 93%(14/15)에서 435bp의 증폭 산물이 관찰되었다. 2) 세포 배양법으로 HCMV가 분리된 소변 15검체를 대상으로 primer IE를 이용하여 중합효소 연쇄 반응을 한 결과 direct gel analysis 법으로는 73%(11/15)에서, 보합 결합법으로는 87%(13/15)에서 관찰되었다. Primer MIE를 이용한 경우에는 direct gel analysis법으로 87%(13/15)에서 435bp의 증폭 산물이 검출되었다. 결 론 : Primer IE와 MIE를 이용한 중합효소 연쇄 반응법은 국내 야생주 HCMV를 신속히 검출하는데 유용한 검사법이다. Background : Human cytomegalovirus(HCMV) can cause pneumonitis, hepatitis, retinitis and other serious diseases in the immunocompromised patients. It takes 1 to 4 weeks to diagnose HCMV infection by conventional virus culture. Therefore, when HCMV diseases are suspected, a rapid diagnostic method such as polymerase chain reaction(PCR), antigen assay or shell vial culture is desirable. We evaluate the sensitivity and specificity of a PCR for the rapid detection of HCMV wild strains in Korea. Methods : We used 2 sets of primers ; primer IE and primer MIE derived from the sequence for immediate early gene of AD169 strain and Towne strain, respectively. Fifteen clinical isolates of HCMV, suspended in MRC-5 cells, were amplified by PCR. Fifteen urine specimens which were positive for HCMV by conventional virus culture were also amplified. Amplification products were analyzed by polyacrylamide gel electrophoresis. The products from PCR with primer IE were also identified by DNA blot hybridization. Results : PCR using primer IE gave the PCR products in all of the 15 HCMV wild strains. All of these were hybridized with probe IE. When primer MIE were used, 93%(14/15) of the wild strains showed amplified bands by direct gel analysis. When the urine specimens were amplified by PCR with primer IE, amplified bands were seen in 73%(11/15) by direct gel analysis ; 87%(13/15) by hybridization method. When primer MIE were used, 87%(13/15) of the urine specimens showed the PCR products by direct gel analysis. Conclusion : Polymerase chain reaction with primer IE and MIE may be a specific and sensitive diagnostic method for rapid detection of HCMV wild strains in Korea.

This study has been aimed to analyze UCHIMATE technique of Judo gymnastically. The following are the results and the proposition obtained through an image analysis method 3 men half heavy weight champions of the national Judo standing team(85-95kg) were used as subjects for the study. 1. CONCLUSION The following are the conclusion obtained through the discussion of analysis results of the Uchimata technique using 3 men, half heavy weight(85-95kg) champions of the National standing Judo team. 1) The time performing total technique were 1.48-seconds which was performinglonger than the light heavy weight class of 1.28-seconds by 0.20-seconds, this showed that the heavy weight class players demonstrated the technique later than the light heavy weight class palyers. 2) The average length of moving 1-step leg for attacking was 24.27cm, and 2-step leg moving was 92.87cm on average. Therefore, the shorter the moving distance, the more the technique performing hour could be shortened. 3) In the hanging phase, the moving displacement of the center of gravity of the body weight showed in horizontal, vertical, right and left direction 28.97cm, 21.59cm and 13.57cm respectively. Each of which were longer than the phase of KUZUSHI and TSUKURI. Such results show that the center of gravity of the body in move lift the opponent. This reducing the displacement of body weight from the center toward the right and left direction in the phase of KAKE is considered to be effective in demonstrationg the technique. 4)The central speed of the body was 0.8cm per second on average and the average vertical speed was 0.74cm per second. The speed of right and left movement was 0.51cm per second on average which showed the horizontal speed was the fastest while it is preferred that the vertical speed should be faster than that of the horizontal. 5) Angle of the Trunk showed 98.13 ˚ on average in the hanging phase and the larger the trunk angle, the shorter the needed time to demonstrate the technique, thus making the throw of the opponent over shoulder more advantageous. 2. PROPOSTION The following propositions are suggested through this analysis for further study : 1) It is to be considered that the kinetics in hanging the thigh and the degree of every segment of the body be studied in a more detailed fashion. 2) A study on the technique of thigh hanging in an actual game situation (rather than during mere exercises) is necessary. 3) It is necessary to study the TORI and UKE techniques together. 4) The study of each weight class ought to be performed.

김칠영,이정모,은희봉,신충화,황명신 한국 항공대학교 항공산업기술연구소 1997 航空宇宙産業技術硏究所 硏究誌 Vol.7 No.-

본 연구의 목적은 비행시험으로부터 항공기의 동적 세로 안정 미계수를 결정하는 것이다. 일반적으로 미계수를 결정하는 방법은 풍동시험 방법, 분석적 방법 그리고 비행시험 방법등으로 나누어진다. 앞의 두가지 방법은 미계수 추정에 있어 많은 제한을 갖고 있으며 추정된 미계수의 유효성에도 문제가 있다. 따라서 비행 시험은 가장 정확한 미계수를 얻을 수 있는 방법이며 반드시 필요한 절차이다. 쌍발 복합재 항공기의 비행시험을 통해 자료를 획득하였고 최대공산법을 이용하여 세로 조종/안정 미계수를 추정하였다. 추정된 미계수를 이용하여 항공기의 운동을 시뮬레이션하여 실제 시험자료와 비교하여 좋은 결과를 나타냄을 알 수 있었다. The purpose of this paper is to find how to determine the longitudinal controllability and stability derivatives from flight test and to display the longitudinal stability of the Twinbee aircraft. There are various methods developed to find the derivatives : wind tunnel testing, predicted result from empirical data, flight test and so on. Among those methods, the estimation from flight test of real aircraft is the most reliable. We performed the flight test of Twinbee and recorded the states of aircraft. Using those states and parameter estimation algorithem based on the Maximum Likelihood (MMLE) criterion, we can estimate the controllability and stability derivatives. In this paper, we will show the process from designing the proper flight test input to estimation of derivatives.

The purpose of this study was to investigate the effect of knee exercises on the onset times of vastus medialis oblique muscle (VMO) and vastus lateralis muscle (VL) and in healthy subjects. Fifteen subjects (7 men, 8 women) in a mean age of 25.4 years participated in the study. Electromyographic (EMG) signals were recorded from the VMO and VL under four exercises. Knee exercises consisted of open kinematic terminal knee extension, straight leg raising, isometric hip adduction exercise, and closed kinematic terminal knee extension. No significant differences were found in the onset times of EMG activities of VMO and VL in the four exercises. There were also no significant differences among the exercises. These results coincided with previous studies that found no difference between onset of VMO and VL. However, it is difficult to say that there is no difference between onset of VMO and VL in healthy subjects. To confirm this results, further researches that follow same onset determination metod and exercises are needed. Not only is the study of onset time of muscle needed, but also the studies of the amount of activation and the rate of increase of muscle activation are needed.

김명섭,신원철 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.4

토양으로부터 α-1,3-glucanase를 생산하는 미생물을 분리하여 동정과 배양조건을 검토하였다. 분리 균주는 회색 계통의 기균사를 형성하였으며 배면 색깔은 적갈색을 나타내었다. 또한 분리 균주의 생육온도 범위는 10~42℃이었고 생육 pH 범위는 pH4~10이었다. 그 외 catalase 양성, esculin, gelatin 및 casein 분해능이 있었다. 당의 이용성과 산 생성 여부를 검토한 결과 arabinose, dextrin 및 mannose에서 이용성을 나타내었고 cellulose를 비롯한 일부 당에서 산이 생성되었다. 분리 균주의 세포벽 구성 성분의 분석 결과 LL-DAP와 glycine을 함유한 세포벽 type Ⅰ으로 분류되었다. 세포벽 구성 아미노산 중 glycine과 alanine의 존재, 기균사의 형성, 수용성 색소 형성, melanoid 색소 형성 및 spore chain 형태 등의 결과로부터 분리 균주는 새로운 Streptomyces 속임을 알 수 있었다. 분리 균주를 이용한 α-1,3-glucanase의 생산은 초기 pH7, 37℃에서 48시간 배양하는 것이 약 0.65 units/ml로 가장 좋았다. A strain producing α-1,3-glucanase was isolated from soil samples. The strain has a grey aerial mycelium and showed brown color from the other side. The temperature and pH range for growth were from 10℃ to 42℃ and from 4 to 10, respectively. Arabinose, dextrin and mannose were utilized for growth. Analysis of cell wall components revealed that the strain was classified as type I. From the results, the strain was identified as Streptomyces sp. By using this strain, the maximum production of 0.65 units/ml for α-1,3-glucanase was achieved at 37℃ for 48 hrs.
