The purposes of the study were to examine students` attitudes toward science and to investigate the relationship between attitudes toward and achievement in science. In order to achieve the purposes, the data collected from the National Assessment of Educational Achievement in 2001 were analyzed in this study. Approximately 1% of students within the entire population of the Grades 6, 9, 10 were randomly selected for the National Assessment of Educational Achievement in 2001. Students at all grade levels had slightly positive attitudes toward science. Positive attitudes toward science were higher at elementary level. Male students had more positive attitudes than female students and the difference in attitudes between male and female students was statistically significant. Also, there were significant differences in students` attitudes toward science among regions including Seoul, metropolitan city, small city and town. In addition, achievement in science was significantly and positively related to attitudes toward science, that is, the higher the students achieved, the more positive their attitudes toward science.

Sludge reduction by the sub-critical wet air oxidation (SCWAO; at <250℃ and 30 atm) was studied to find out the optimal operational parameters such as time, temperature, pressure, and oxidant dose. The initial suspended solids (SS) and total chemical oxygen demand (TCOD) concentrations of sludge used for the laboratory-scale experiment were 6,500 and 7,500 ㎎/L, respectively. When the temperature changed from 180 to 260℃ with 20℃ intervals, higher temperature was shown with higher TCOD removal efficiency at around 75%, and the soluble chemical oxygen demand (SCOD) was increased abruptly up to 2,000 ㎎/L within 10 min. At the same time, SS was decreased as SCOD increasing, implying organicsolids were liquefied during the process, with about 70% of SS decomposed within 10 min, whereas the organic acid concentration increased rapidly within 20 min. The higher temperature also resulted in higher organic acid concentration. Based on the results from the lab-scale experiments, a pilot plant with the capacity of 3 ㎥/d was designed and then operated at 60 min hydraulic retention time (HRT), 220℃, and <30 atm. Air was injected into the WAO reactor for the higher oxidation efficiency, at the flow rate of 50% of the stoichiometric oxygen requirement. The removal efficiencies for total solids and TCOD at 220℃, 30 atm, and 60 min HRT were over 70% and 40%, respectively, and the yields of volatile fatty acids (VFAs) and SCOD were 115 g VFAs/㎏ SS and 730 g SCOD/㎏ SS, respectively.

본 논문에서는 과학예술영재학교 교육과정 과정을 Walker의 자연주의 교육과정 개발 모형에 기초하여 플랫폼, 숙의, 설계 단계로 나누어 조망함으로써 고등학교 수준의 융합교육의 가능성과 바람직성을 탐색하고 향후 발전과제들을 제시하고자 하였다. 플랫폼 단계에서는 융합이 교육개혁의 화두가 된 사회환경과 과학과 예술의 융합이 기획된 이론적, 실천적 근거를 분석하였고, 숙의 단계에서는 융합교육을 통해 기르고자 하는 인재상과 핵심역량, 융합교육의 정의 및 접근 방식에 대한 쟁점과 대안들을 확인하였다. 설계 및 타당화 단계에서는 융합교육개발 과정 상 나타난 쟁점별 대안들에 대한 적합성 평가를 통해 최적의 대안에 대한 선택 과정과 결과를 제시하였다. 본 연구에서 전문가와 현장교원의 숙의과정을 통해 고등학교 수준의 융합교육과정의 가능성과 바람직성을 탐색해 본 결과, 고등학교 수준의 융합교육 융합된 내용을 가르치는 것이 아니라, 융합적 사고방식을 기르는 방식으로 접근해야 하며, 고등학교 단계에서 다양한 학문 분야를 경험하고 해당 학문의 핵심 개념을 익히고, 이들을 연결지어 전체를 보는 통합적, 종합적 안목을 기르는 일은 가능할 뿐 아니라 바람직하다는 결론에 도달하였다. 또한 융합교육의 발전 과제로 융합교육 개념의 명료화, 전생애적 관점에서의 융합교육 설계, 교육적 적합성 제고를 위한 융합교육의 조건, 과학과 예술 간 융합교육의 확대, 일반고로의 확대가능성 타진 등을 제안하였다. The purpose of this paper is to explore the possibilities and desirability of interdisciplinary curriculum at the high school level based on curriculum development processes and products of Science and Arts Academy for the gifted. The processes and products of curriculum development were reviewed through the lens of the Walker`` naturalistic model for curriculum development. In the platform stage, the change of social environments and the theoretical grounds of attempts integrating the domain of science and arts were analysed. During the deliberation stage, the issues and alternatives were identified concerning key competencies, the definition and diverse approaches of interdisciplinary curriculum, and the curriculum structure design. In the design and validation stage, the processes and products of a set of design decisions were presented. Through the deliberation process on the possibilities and desirability of the interdisciplinary curriculum at the high school level, we conclude that the interdisciplinary curriculum needs to focus on fostering the interdisciplinary skills rather than attempting to teach a subsumption of disciplines. In the high school level the excessive specialization should be sublated and students are to be led to the global optimization through the wide exposure to various disciplines and experiences . As the keys to the successes of the interdisciplinary curriculum, clarification of the meaning and purposes of interdisciplinary curriculum, the needs of entire life cycle design for interdisciplinary learning, and the validity criteria of interdisciplinary curriculum were presented.

Dyke-Davidoff-Masson symdrome is a rare disorder which developed hemiatrophy of brain, enlargement of ventricles and prominent pneumatization of petrous pyramid of the temporal bone. It manifests hemiparesis,varying type seizure,and mental retardation. We experienced three cases of Dyke-Davidoff-Masson syndrome,in a 6 7/12year-old boy. a 5 year- old boy and a 6 11/12 year-old boy who were visited to our department of pediatrics,because of convulsion and/or hemiparesis. The brain CT scan showed marked dilation of lateral ventricle.porencephaly and calcification in parietal lobe. So we report three cases of Dyke-Davidoff-Masson syndrome with review of literature.

Background: Ozone (0₃) induces airway inflammation and hyperresponsiveness which are characteristic features of asthma. There have been few studies observing O3₃induced increase in responsiveness of rat airway muscle. Objectives: The aims of this study were to develop an O₃-induced nonallergic asthma model using rat tracheal smooth muscle (TSM) and to evaluate the role of airway epithelium on the modulation of muscle responsiveness. Method: Five groups of 20 male Sprague-Dawley(SD) rats were exposed to filtered air including 0.12, 0.5, 1.0, or 2.0 ppm 0₃for 1 hour. Thirty minutes after the exposure, bronchoalveolar lavage (BAL) and isometric contractile responses of the isolated tracheal ring segments to KCI, acetylcholine (ACh), and electrical field stimulation (EFS) were measured. Results: The percent age of neutrophils was significantly higher and that of alveolar macro-phages in BAL fluid was significantly lower in 2.0 ppm O₃-exposed rats than in the control. There were no significant differences in the maximal contractile responses of TSM to KC1, ACh, EFS and in the sensitivity to ACh (ACh-EC_(50)) and EFS (EFS-EC_(50)) between the control group and the ozone exposed group. ACh-EC_(50) and EFS-EC_(50) were correlated positively with the percent age of neutrophils and inversely with that of macrophages. Removal of epithelium significantly increased the sensitivity to ACh in O₃-exposed group, but not in the control group. Conclusion: These findings indicate that O₃induces neutrophilic airway inflammation, but not an increased sensitivity of TSM to ACh or EFS in SD rats. However, O₃-induced epithelial damage may be associated with increased muscle response.
