중학교 과학 교과서에서 요구하는 수학 관련 과학 개념의 수준 및 학생들의 인지 수준 분석: 2015 개정 교육 과정의 화학과 생물을 중심으로

This study aimed to analyze students' cognitive levels and the cognitive demands of mathematical concepts related to science to understand why students struggle to comprehend scientific concepts and tend to avoid learning them. Initially, the mathematics and science curricula of the 2015 revised curriculum were examined to extract learning elements related to mathematics within middle school science content. The Curriculum Analysis Taxonomy (CAT) was then employed to analyze the cognitive levels required by the learning content. In the domain of chemistry, among a total of 20 learning elements related to mathematics, 12 required an understanding at the level of initial formal manipulation (3A), while 3 necessitated comprehension at the level of later formal manipulation (3B). It was noted that cognitive logic types such as proportional reasoning, mathematical manipulation, and measurement skills were prominently employed in elements corresponding to both 3A and 3B. As for biology, out of 7 learning elements related to mathematics, 3 required an understanding at the level of initial formal manipulation (3A), and 2 necessitated comprehension at the level of later formal manipulation (3B). Elements corresponding to both 3A and 3B in biology predominantly involved correlational logic, indicating a somewhat different cognitive challenge compared to the domain of chemistry. Considering that the average percentage of middle school students capable of formal thinking, as analyzed through the GALT short form, was 12.1% for the first year, 16.6% for the second year, and 29.3% for the third year, it can be concluded that the cognitive demands of mathematics-related chemistry and biology learning content are relatively high compared to students' cognitive levels.

Background: This study aimed to examine the environmental tobacco smoke (ETS) exposure at home and associated problem behaviors in Korean children and adolescents. Methods: Approximately 2,167 children aged 3–18 years were included in the study after excluding 163 active smokers from the Korean Environmental Health Survey in Children and Adolescents (2012–2014). ETS data were obtained using a questionnaire; problem behaviors were measured using the Child Behavior Checklist administered to parents. The relationship between ETS exposure and problem behavior was evaluated using a survey regression model adjusted for region, age, sex, income, and father's education. The population-attributable fraction (PAF%) was calculated based on problem behaviors related to ETS exposure at home. Results: The rates of ETS exposure at home were 20%, 28%, and 39% in children aged 3–5, 6–11, and 12–18 years, respectively; ETS exposure at home was associated with behavioral problems: the exposed group having higher total behavioral problem score (95% confidence interval [CI]) than the non-exposed by 2.46 (0.60–4.32) and 2.74 (0.74–4.74) in children aged 6–11 and 12–18 years, respectively, with no significant association in those aged 3–5 years. The PAF% (95% CI) of total problem behaviors for ETS exposure at home were 2.68 (−10.11–17.78), 10.66 (3.25–17.55), and 11.62 (3.03–18.96) in children aged 3–5, 6–11, and 12–18 years, respectively. Children with externalizing problems had higher PAF% than those with internalizing problems. Conclusion: In Korea, ETS exposure at home is associated with problem behaviors in children and adolescents with about more than 10% population attributable fraction.

고정익 전투기에 적합한 통합전장환경 전시용 "차세대 항공기용 디스플레이"(Next Generation Avionics Display; NGAD) 프로토타입을 제안한다. NGAD 의 해상도는 1920 X 800 이며 직관적인 데이터 입력을 위해 IR 방식을 사용한 고감도의 터치스크린을 적용하였다. 오토 파일럿, 항법, 무장, TSD Map 등 비행/임무 정보를 효과적으로 전달할 수 있도록 Man-Machine Interface 에 중점을 두어 화면설계를 하였다. 제안된 NGAD 를 실제 전투기와 유사한 Cockpit 에 장착하여 모의비행환경에서 연동하였다. This paper proposes the "Next Generation Avionic Display; NGAD" prototype that meet exhibition of integrated battlefield environment for fixed-wing aircraft. The resolution of NGAD is 1920 X 800 and IR Touch Screen technology is used for intuitive data input. The screen configuration of NGAD is designed with emphasis on Man-Machine Interface for indicating flight/mission information such as Autopilot, Navigation, Weapons, TSD MAP effectively. The proposed NGAD equipped on the fighter-grade simulator cockpit is interfaced with flight simulator environment.
