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.

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.

1994년 2월에 경상북도 경주시 배반동 중마을에서 탄저병 환자가 집단으로 발생하였다. 환자들은 죽어가는 소를 먹고 위장관형 탄저병에 걸렸으며, 28명이 발병하여 3명이 죽었다. 저자들은 집단 발병 환자중 1명으로부터 편도선에서 탄저균을 분리하였다. 환자는 쇠간을 날로 먹고 감염되었으며, 편도선염과 같은 임상 증세를 보였다. 우리나라에서 탄저병은 위장관형 탄저병이 집단으로 발생하는 특성이 있다. 쇠고기를 먹은 사람들에게 편도섬염, 목의 부종, 또는 위장관 증세가 집단으로 발생하면 탄저병을 감별하는 것이 중요하다. An outbreak of anthrax occurred in a village of Kyungsangbookdo province in February, 1994. The source of infection was raw meat and liver from an infected cow. Among those who ate the meat or liver, 28 developed gastrointestinal anthrax, and 3 patients died. We report a patient with anthrax tonsillitis. She ate raw bovine liver. The diagnosis was confirmed by the isolation of Bacillus anthracis from a tonsillar swab. Epidemiologically anthrax in Korea occurs as an outbreak of gastrointestinal anthrax by the ingestion of beef. Gastrointestinal anthrax should be considered in the differential diagnosis of a food-borne outbreak caused by ingestion of raw bovine meat.

An experimental study presents characteristics of combustion in a combustion chamber by port deactivation valve for economy and emissions standards. In order to use combustion properties data, it is necessary to build some data base, which use cylinder pressure sensor, etc. Port deactivation valve has been developed to satisfy requirement of achieving sufficient swirl generation to improve the combustion. A feasibility and necessity of combustion pressure based cylinder spark timing control has been examined. So, this was obtained the Coefficient of Variation(COV) and the mass-burned(MFB). The characteristics of pressure ratio fraction is similar to that of mass-burned fraction. Using the results of the test, the effects of the combustion chamber can be improved combustion stability by port deactivation.

Minimal inhibitory concentrations of total 148 strains isolated from blood culture at Seoul National University Hospital were determined by Vitek System. 90% MIC of gram-negative bacteria against amikacin was 2-16㎍/㎖, and those against beta-lactams was > 16㎍/㎖ in general, Except Salmonella spp,. 90% MIC against chloramphenicol and tetracycline was >8㎍/㎖. Range of 90% MIC against vancomycin was ≤.5-4㎍/㎖ in case of garm-positive bacteria, except Enterococcus spp. which showed 90% MIC as >16㎍/㎖. Against ampicillin, 90% MIC of Staphylococcus spp. was >16㎍/㎖, but those of Streptococcus spp. was ≤.25-2㎍/㎖. Streptococcus viridans group showed 90%MIC against penicillin as ≤.03㎍/㎖. Susceptibility of gram-negative bacteria was generally 98% against amikacin, and those of gram-positive bacteria was 80% against vancomycin. 34% of Staphylococcus spp. was resistant of oxacillin. These results may be useful for the primary selection and the dosage determination of antibiotics in the treatment of patients with bacteremia.

DBD(Dielectric Barrier Dischages) plasma is often used to clean the surface of semiconductor. The cleaning performance is affected mainly by plasma density and duration time. In this study, the plasma density is predicted by coupled simulation of flow, chemistry mixing and reaction, plasma, and electric field. 13.56 MHz of RF source is used to generate plasma. The effect of dielectric thickness, gap distance, and flow velocity on plasma density is investigated. It is shown that the plasma density increases as the dielectric thickness decreases and the gap distance increases.

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.
