20 preservice teachers at college level participated in this study and interacted with students at elementary and middle school levels during science camp offered by science center in Taiwan. Preservice teachers displayed moderate (above the average, 4 point out of 5) understandings about scientific literacy and scientific views in all aspects of the nature of science before the camp. Then, the researchers designed science camp programs which were expected to promote students' scientific literacy; scientific knowledge, inquiry skills for experimentation as well as for argumentation, affective domain such as the attitude toward science and the understandings about nature of science and the relationship among STS (Science-Technology-Society), all of which were embedded in the programs. Preservice teachers seemed to perceive scientific literacy pretty well (over 4 point) before the camp, however, preservice teachers' understandings about scientific literacy were not much scored (around 3 point, but still moderate scores of average) as expected after concrete inquiry activities. The reasons why this happened could be that preservice teachers were not trained to employ theory into the context to be more practical or the researchers did not develop camp program which included the aspect of scientific literacy successfully. The discussion and implication were made in teacher education in that preservice teachers must be prepared how to bridge theory into practice, and informal science education in that educators at science centers must be trained to be experts in providing the envisioned educational programs to meet the goal of science education, scientific literacy.

본 연구는 과학계고등학교 11학년 '산화-환원' 단원에 대해 자기조절학습 전략을 활용한 실험수업을 실시한 후, 과학탐구능력, 과학적 태도 및 학업성취도에 대한 교수-학습 효과를 분석하였다. 통제집단에 대해 교과서 및 교사용 지도서에 따라 실험수업을 실시하였으며, 실험집단에 대해서는 자기조절학습 전략을 활용한 실험수업을 실시하였다. 사전검사에서 두 집단 간에 유의미한 차이가 없었으나, 사후검사에서 실험집단의 평균값이 유의미하게 차이가 나타났다. 자기조절학습 전략을 활용하여 실험수업을 처치한 후, 과학고 학생들의 성향에 따른 자기조절학습 요소의 평균값 차이를 조사하였다. 사후검사의 인지조절 및 동기조절에서는 유의미한 차이가 나타났으나, 행동조절에서는 차이가 없었다. 과학탐구능력의 실험설계, 가설설정, 변인통제 및 일반화에 대해 두 집단사이에 유의미한 차이가 나타났다. 까다로운 변인통제가 실험의 성공여부와 직결된다는 생각에, '변인통제'를 신중하게 처리하였다. 이런 경향성은 실험횟수가 진행될수록 자기조절학습 전략에 대한 자신감이 생겼으며, 실험활동을 스스로 통제 조절하려는 노력이 더 적극적으로 나타났다. 이 같은 결과에 의해, 이들 요소에서 유의미한 차이가 생겼을 것으로 생각된다. 자기조절학습 세부요소와 과학탐구능력 사이에 상관성이 유의미하게 나타났으며, 인지요소에서 가장 높게, 행동조절에서 가장 낮은 상관관계를 나타내었다. 과학적 태도에서 두 집단 간에 평균값의 차이가 유의미하게 나타났다. 신중성, 자진성 및 호기심에서 평균값의 차이가 크게 나타났다. 자기조절학습 능력과 과학적 태도 사이에 유의미한 상관관계가 나타났으며, 인지조절과 동기조절에서 유의미한 상관관계가 나타났다. 과학적 태도의 하위변인인 신중성, 자진성 및 호기심에서 높은 상관성을 나타내었다. 학업성취도에 대해 실험집단의 평균점수가 약간 높게 나타났다. 자기조절학습 요소들과 학업성취도 사이에 유의한 상관성이 나타났으며, 인지조절과 동기조절에서 유의미한 상관관계를 나타내었다.

Objective : To find a collaboration strategy between western medicine and traditional Korean medicine (KM), this study aims to figure out the changes in the perception and attitude of medical doctors toward KM through systematic review. Method : Systematic literature searches were performed on six Korean databases. Studies were categorized according to the respondents and question items and analyzed by the context of questions, similarity of respondents and measurement scale. And we analyzed the changes of response regarding to medical doctors' and medical students' perspective and attitude to KM. Results : Eighteen survey studies including attitude of medical doctors and medical students toward KM were selected, which were conducted from 1993 to 2011. Although the attitude toward KM did not show any positive change, medical doctors have had more interest in acupuncture than herbal medicine and appreciated KM's treatment effect for musculoskeletal disease. In spite of little KM education experience, they had intentions for acupuncture education at least. Many medical doctors have listed the unscientific aspect as a major reason why they cannot trust KM. Medical doctors working for cooperative practice showed more positive attitude than other medical doctors and medical students had more positive attitude in general than medical doctors Conclusion : Though the growth of KM service and cooperative practice since 1990s, medical doctors' attitude toward KM seems to become more negative. To improve their attitude, making scientific evidences for KM is required as well as giving more education and treatment experience.

본 연구의 목적은 SSS 실험수업이 중3학생들의 과학에 관련된 태도와 과학적 태도에 미치는 효과를 알아보는 것이었다. 포항에 있는 중학교에서 두 학급이 선택되었고, 두 집단으로 분류되었다: 26명으로 구성된 실험집단은 SSS를 활용한 과학 실험수업에 참가하였고, 25명으로 이루어진 비교집단은 전통적 실험수업에 참여하였다. 이 연구의 주요 시사점은 다음과 같다: SSS 실험수업은 학생들의 과학에 관련된 태도와 과학적 태도에서 실험집단에 긍정적인 영향을 미치고 있었다. 그리고 과학에 관련된 태도와 과학적 태도의 하위영역에서 실험수업 전후에 유의미한 차이를 나타내었다. 반면에 비교집단에서는 유의미한 차이가 없었다. 결론적으로 SSS를 활용한 학급은 학생들의 과학에 관련된 태도와 과학적 태도 형성에 좋은 영향을 받는다는 것을 시사한다. 특히 과학교과에 대한 태도와 같은 과학에 관련된 태도의 하위요소 향상이 두드러지고, 과학적 태도의 하위요소인 호기심, 비판성, 협동성, 자진성, 끈기성, 독창성이 SSS 실험수업 후에 향상된다. 그러므로 SSS 실험수업이 적용될 때 학습태도를 개선할 수 있다.

In this study of the relative effectiveness of constructivist and non-constructivist approaches to shadow activity for young children, 59 children in two kindergarten classes were assigned to constructivist or non constructivist conditions. Each group participated in 12 units covering shadow search, shadow making, changing shadow size, changing shadow position, and shadow disappearance. Analysis of covariance of differences between the mean scores of the two groups on the posttests of shadow concepts and scientific attitudes revealed that the children in the constructivist group performed better than the children in the non-constructivist group. This confirms the constructivist approach to shadow activities as good science activities for young children by promoting their active experimentation using reasoning about light to foster spatio-causal relations construction.

KOMPSAT is a three-axis stabilized light weight satellite, and one of the main mission objectives of the KOMPSAT is to conduct scientific and technological analysis in the areas of high resolution imaging and ocean color imaging. This kind of mission requires the satellite to roll up to 45 degrees. Bang-bang control for this rolling maneuver may activate the flexible modes, and therefore cause satellite pointing performance degradation. To deal with this problem, the roll attitude control system, especially for the science mode and maneuver mode of the KOMPSAT, is first verified by numerical simulation. And the open-loop control law for roll maneuver is proposed by use of series expansion and optimization. The proposed control law is applied to KOMPSAT to see its effectiveness.

Author Studied on a few as Pacts of clinical psychology of 274 patients with chronic pulmonary tuberculosis by simple question are, who had been admitted in national Maison for a long time Feb. 1971, Hospital. The results obtained were Summarized as follows: 1. The attitude and state of understanding to their diseases were somewhat different between males and females, That is, rather scientific and intellectual in males but rather unscientific and despairing in females. 2. The attitude to their doctors and nurses were rather more discontent in males and younger age group. 3. Attitude to hospital life what was some different between males and females, that is, more agreeable and obedient to their circumstances in females and older age group than in males and younger age group. 4. The most anxious problem and the Persons who Eave best consolation during hospital life were family members in their home. 5. The home visiting of the nurses seemed under whole net welcomed.
