        과학에 대한 태도와 과학 성취도의 관계

        이미경 ( Mee Kyeong Lee ),김경희 ( Kyung Hee Kim ) 한국과학교육학회 2004 한국과학교육학회지 Vol.24 No.2

        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.

        Background: Ozone (03) induces airway inflammation and hyperresponsiveness which are characteristic features of asthma. There have been few studies observing O3-induced 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 in- cluding 0.12, 0.5, 1.0, or 2.0 ppm 03 for 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-EC50) and EFS (EFS-EC50) between the control group and the ozone exposed group. ACh-EC50 and EFS-EC50 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 O3 induces 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.

        안재환(Jae-Hwan Ahn),김미경(Mee-Kyung Kim),이미경(Mi-Kyung Lee) 한국유체기계학회 2006 유체기계 연구개발 발표회 논문집 Vol.- No.-

        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.

        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.

        융합교육과정 개발에 대한 숙의: 과학예술영재학교 교육과정 개발 과정을 중심으로

        김주아 ( Ju Ah Kim ),김영민 ( Young Min Kim ),이미경 ( Mee Kyung Lee ) 한국교육과정학회 2014 교육과정연구 Vol.32 No.4

        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.
