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.

The inverted papilloma and squamous cell carcinoma are common neoplasia in the sinonasal cavity and nasopharynx, but the incidence of these tumors are very low and the study on the oncogenesis or biological activity of the tumor cells are not well known. This study was designed to evaluate the oncogenic roles of the p53 gene and the proliferative activity of the tumor cells in the inflammatory polyp, inverted papilloma and squamous cell carcinoma. The experiment was carried by the immunohistochemical stains about the p53 protein, PCNA and Ki-67, histochemical stain about the AgNORs. and flow cytometric analysis about the DNA ploidy using the formalin fixed paraffin embedded tissues. The frequency of the expression of p53 protein was 0%(0/16 cases) in the inflammatory polyps, 18.8% (3/16 cases) in the inverted papillomas, and 87.5%(14/16 cases) in the squamous cell carcinomas. The labelling index(%) of the PCNA and Ki-67 was 5.3% and 3.3% in the inflammatoy polyps, 29.6% and 25.2% in the inverted papillomas, and 51.9% and 36.8% in the squamous cell carcinoma. The expression of the PCNA and Ki-67 was distributed in the periphery of the tumor islands of the inverted papilloma and was distributed in the both of center and periphery of the tumor islands of the squamous cell carcinoma. The number of nuclear AgNORs was increased in the order of inflammatory polyps (0.96), inverted papillomas(1.34) and squamous cell carcinoma(2.09). The frequency of the DNA aneuploidy was 0%(0/16 cases) in the inflammatory polyps, 18.8%(3/16 cases) in the inverted papillomas. and 12.5%(2/16 cases) in the squamous cell carcinomas. Above results indicates that the changes of the p53 gene and proliferative activity of the tumor cells are involved on the oncogenesis and the biological activity of the inverted papilloma or squamous cell carcinoma in the nasopharynx and sinonasa cavity.

기현균,김연숙,정숙인,김춘관,김신우,김성민,백경란,송재훈 대한화학요법학회 2000 대한화학요법학회지 Vol.18 No.3

목적 : Mefliquine은 가장 널리 사용되는 말라리아의 화학적 예방약이지만 경련, 정신병 증상 등의 심각한 신경학적 부작용을 포함한 여러 가지 부작용을 일으킬 수 있다. 이러한 부작용은 인종간에 차이가 있는 것으로 알려져 있으나 아직까지 우리나라에서는 mefloquine에 대한 내약성에 관한 구체적인 자료가 없다. 이에 저자 등은 한국인에서의 mefloquine의 내약성을 전향적으로 조사하였다. 방법 : 1997년 6월부터 1999년 4월까지 삼성서울병원 여행의학 클리닉에 내원한 총 180명의 열대열 말라리아 위험지역으로 여행하고자 하는 여행객들을 대상으로 하였으며 이들은 여행 1주전부터 귀국 후 4주까지 mefloquine을 주 1회 복용하였다. 이들에게 여행자 수첩을 배부하고 약제 복용 후 발생한 증상을 기록하도록 하였고 동시에 여행자들에 대한 전향적 관찰 및 병록지 검토를 시행하였으며 귀국 후 3개월째 전화조사를 시행하여 mefloquine복용 당시의 부작용과 동반증상 여부에 관하여 평가하였다. 성적 : 총 180명의 여행자가 연구에 포함되었으며 이중 166명에 대하여 평가를 시행하였다(166/180, 92.2%). 연구대상 중 남자가 104명(104/166, 62.7%), 여자가 62명이었고(62/166, 37.3%) 평균연령은 36.4세였다(36.4±15.2). Mefloquine은 평균 6주간 투여하였다. 평가에 포함된 여행자 166명 중 4명에서 부작용이 나타났으며(2.4%) 부작용 발현건수는 6건이었다(3.6%). 나타난 부작용은 현기증이 2건(1.2%), 비정상적인 꿈, 수면장애, 기분저하, 발열이 각각 1건씩 발생하였다. 이중 증상과 약제와의 관련성이 있는 경우는 1명에서만 나타났으며(0.6%) 투약을 중지한 후 증상이 소실되었다. 나머지 3명의 여행자는 모두 mefloquine을 처음 복용할 당시에 일시적인 증상이 있었으나 부작용과의 인과관계는 확실하지 않았고 증상은 곧 소실되었다. 연구대상 환자 중 말라리아가 발병한 증례는 없어 100%의 예방효과를 보였다. 결론 : 총 166명의 연구대상 중에서 mefloquine에 대한 내약성이 불량한 경우는 1예 였으며(0.6%), 심각한 신경학적, 정신과적 부작용은 나타나지 않았다. 이러한 결과는 한국인 여행객들의 mefloquine에 대한 내약성이 우수함을 시사한다. Background : Mefloquine is the most commonly used chemoprophylactic agent against malaria. Many kinds of adverse reactions of mefloquine including neuropsychiatric adverse reactions, have been reported. It has been thought that the incidence of mefloquine-related adverse reactions may be different among the races. Since data on Korean people are not available, we investigated the incidence of mefloquine-related adverse reactions in Korean travelers prospectively. Methods : We gave a notebook to each visitor to Travel Medicine Clinic of the Samsung Medical Center, who had a plan to take a trip to the endemic area of malaria by Plasmodium falciparum. The study duration was from June 1997 to April 1999. They took mefloquine weekly from I week before the trip to 4 weeks after the trip. They wrote any adverse reactions on the notebooks by themselves. We surveyed the travelers by clinical observation, reviewing the medical records and telephone interview at 3 months after the trip. Results : One hundred eighty travelers were included in the study and 166 of them were evaluable (166/180. 92.2%). One hundren four travelers were male (104/166, 62.7%). The mean age of travelers were 36.4 years (36.4±15.2 years). The median duration of chemoprophylaxis were 6 weeks. Four of the enrolled travelers had adverse reactions (4/166, 2.4%) and six episodes of adverse reactions were occurred (6/166, 3.6%) : dizziness (2 cases), bizzare dream (1 case), sleep disturbance (1 case), mood change (1 case), and febrile sense (1 case). Only one traveler with persistent dizziness stopped mefloquine, and then dizziness was relieved. The other symptoms were transient, which were relieved despite continuation of mefloquine. No case of malaria was found in this study. Conclusion : Only one episode of adverse reactions was thought to be related to the mefloquine (0.6%). No case of severe neuropsychiatric adverse reactions was observed. This study suggests that mefloquine tolerance in Korean travelers is excellent.

In performance-based design methods, it is clear that the evaluation of the nonlinear response is required. Some codes proposed the capacity spectrum method(CSM) based on the nonlinear static analysis to determine earthquake induced demand given the structure pushover curve. This procedure is conceptually simple but iterative and time consuming with some errors. The nonlinear direct spectrum method(NDSM) is proposed and studied to evaluate nonlinear response of structures, without iterative computations, given by the structural linear vibration period and yield strength from the pushover analysis, especially for shear buildings system. The purpose of this paper is to compare accuracy of approximate nonlinear methods with respect to various structure characteristics.

Anatomic abnormalities of teeth development include the presence of a single maxillary central incisor at midline instead of two central incisors. The incidence of cases with a single maxillary central incisor is approximately 1 in every 50,000 live births. single median maxillary central incisor(SMMCI) may be a integral manifestation of anyone of a number of syndromes. It has been reported an association with several midline disorders which have varied in severity. A SMMCI has also been reported as an isolated finding. But in some cases, it has been considered as an incomplete expression of autosomal dominant holoprosencephaly. So any patient who appears for treatment with a SMMCI should be referred for a detailed medical examination to exclude other associated systemic abnormalities and for mutation analysis to facilitate correct diagnosis and the provision of appropriate genetic counseling. Early orthodontic treatment is needed to minimalize emotional trauma of child. This case report was about three patients with a SMMCI as isolated finding. The purpose of these case reports was to present cases of single maxillary central incisor not associated with other disorders. Single Median Maxillary Central Incisor(SMMCI)는 상악 중절치 형성부전으로 하나의 상악 중절치가 정중앙에 위치하는 치아 발달의 해부학적 이상을 의미한다. 50,000명 중에 1명 꼴로 발생할 정도로 아주 드물며 각종 증후군 및 정중선 이형성을 보이는 발달장애와 연관되어 나타나는 것으로 보고되고 있다. SMMCI는 다른 이상과 연계되지 않고 독립적으로 나타날 수도 있으나 상염색체 우성유전인 전전뇌증(holoprosencephaly)의 경미한 발현일 가능성이 있으므로 유전자 상담이 필요하다. 또 특징적인 안모 및 구강 상태를 보이므로 환아의 바람직한 신체적,정서적 발달을 위해 조기에 교정적 접근이 필요하다. 본 증례는 다른 이상 소견을 보이지 않는 세 명의 SMMCI 환아의 증례를 보고하는 바 이다.

Bi계 산화물 초전도체 2212상에 있어서 Bi 자리에 Ge 치환에 따른 초전도 특성

신재수,이민수,최봉수,송승용,송기영 대전산업대학교 반도체기술연구소 2000 半導體技術硏究所報 Vol.2 No.-

고상반응법(solid-state reaction)으로 산화물 초전도체 Bi_2-xGe_xSr_2CaCu_2O_8+8(x=0, 0.1, 0.2, 0.3, 0.4, 0.5)을 제조하여 치환에 따른 산소량의 변화가 초전도 특성에 미치는 영향에 관하여 조사하였다. 이차 가압(intermediate press) 방법으로 제조한 시편은 온도 폭 △K(온도 임계온도 T_c^on과 영저항 임계온도 T_c^zero와의 차)가 상당히 감소함을 알았으며 80 K 단일상 고용한계는 Ge 치환량이 x<- 0.3영역임을 알았다. 고용한계 영역 내에서 Ge 치환량 x의 증가에 따라 격자상수 c가 감소함을 보였으며, 온셋 임계온도 T_c^on은 증가하였고, 과잉(여분) 샨소량은 감소함을 보였다. Samples with the nominal composition, Bi_2-xGe_xSr_2CaCu_2O_8+8(x=0, 0.1, 0.2, 0.3, 0.4, 0.5) were prepared by the solid-state reaction method. We have studied the effect of substitution Ge for Bi and investigated the superconducting properties by changing oxygen content with Ge substitution. It was found that temperature difference, △K, between T_c^on and T_c^zero was considerably smaller in the samples prepared by the intermediate pressing method than that in the samples by the solid-state reaction method. We found the solubility limit of Ge to the 80 K single phase, the onset critical temperature T_c^on increased and excess oxygen content decreased with increase of x.

In an effort to develop design methods based on performance it is clear that the evaluation of the inelastic response is required. The methods available to the design engineer today are nonlinear time history analyses, or monotonic static nonlinear analyses, or equivalent static analyses with simulated inelastic influences. Some codes proposed the capacity spectrum method based on the nonlinear static(pushover) analysis to determine earthquake-induced demand given the structure pushover curve. This procedure is conceptually simple but iterative and time consuming with some errors. This paper considers a nonlinear direct spectrum method to evaluate seismic performance of structure, without iterative computations, given the structural initial elastic period and yield strength from the pushover analysis, especially for multi degree of freedom structures. The purpose of this paper is to investigate accuracy and confidence of this method from a point of view of various earthquakes.
