The purpose of this study was to investigate high school students' preference for science(PS) and its causal factors in terms of gender difference, and to suggest the way to improve students' preference for science. A questionnaire to evaluate the PS of high school students and its causal factors was specially designed by researchers. It was administered to 429 boys and 449 girls in eight high schools. The average score of the PS was 3.16 of 5.00 which was not high, but the PS scores of students who had wanted to be engaged in jobs related to science or medical field, were higher than the students who would be in other fields. There was no statistically significant difference between the boys' PS scores and girls', but the average scores of causal factors were higher in boys than in girls. Path analysis using a structural equation model was indicated that the pathways showing how causal factors made effects on each category of the boys' PS were simpler than those of girls. Particularly, while educational factors made indirect effects on three categories of the boys' PS, they did direct effects as well as indirect effect on the girls' PS. This means that the girls' PS is possible to be improved by applying the educational programs specially developed for girls.

우리나라는 선진 대열에 올라설 수 있는 산업을 중심으로 제2의 도약을 계획하고 있다. 이의 핵심분야인 전자공업의 새로운 장을 연 NMR-CT의 국내 개발은 우리 민족의 우수성을 전세계에 알리는 계기가 됨과 동시에 과학입국으로서 세계어느 나라에도 못지 않는 능력을 과시하게 되었다. 최첨단 기술인 NMR-CT는 1980년대부터 의료진단 분야의 주역이 될 것이며, 치열한 세계경쟁 속에 뛰어 들어 선두대열에서 나아가게 될 것이다. 아울러 많은 첨단분야에서 세계 선진국들과의 경쟁대열에 뒤지지 않기 위해서는 이에 관련된 연구진들의 각고의 노력은 물론 정부와 산업체의 적극적인 지원 및 첨단분야에 대한 새로운 인식이 병행되어야 할 것이다.

안전하고 위생적이 우유를 생산 보급하기 위하여 그 동안 정부, 낙농가, 유가공 관련업체 등에서 많은 분들의 꾸준한 노력으로 인해 선진국 못지 않은 고품질의 원유가 생산되고 있으며, 최근에 많은 유업체들이 경쟁적으로 보다 품질좋은 우유를 생산하기 위하여 세균수 일등급에 해당하는 목장 원유만을 따로 집유하는 등 다각적인 방법을 취하고 있는 실정이다. 농촌진흥청 수의과학 연구소(소장: 이재진) 유방염연구실에서는 낙농가가 보다 품질좋은 원유생산을 위해 유방염

과학기술의 패러다임은 생명체가 진화하듯 변신한다. 지난 시간을 돌이켜보아 오늘의 모습과 비교해 보면 변화의 폭을 실감할 수 있다. Samuel C. Prescott 박사(Singh, 1997)에 의해 표현된 식품공학(food engineering)이란 용어가 소개된 시기는 1939년경이었다. 초기 식품공학은 농공학에서 농산물의 수확후 작업과 관련하여 식품제조와 식품가공장치에 관한 내용이 주로 다루어졌으며, 이 시기의 특징을 보여주는 대표적인 저서의 예가 Milton E. Parker가 1952년에 저술한 "Elements of Food Engineering"이다. 1950년대와 1960년대에는 화공학의 단위 조작이 도입되어 현재까지 식품공학의 주요 기법으로사용되고 있는바, 건조, 살균, 냉동, 압출 둥의 공정에서 현저한 성과를 보였다(Karel, 1997).(중략)

The purpose of this paper was to understand the outlines of 1) common and free curricula implemented by the first pilot schools and 2) Home Economics related programs from both curricula. This study analyzed the 42 reports from the first pilot schools which implemented the free learning semester in 2013. The results showed that more than half of schools set two or more emphasis models of the free learning semester. In 15 out of 28 schools, the lesson hours of Home Economics were reduced by one to three hours. Various common curricula were implemented in many aspects of teaching-learning methods, curriculum, evaluation, and subject related career lessons. Free curriculum was implemented in four areas such as career exploration, student optional program, club activity, and art sports activity. In common curriculum, Home Economics was carried out in 17 out of 39 schools. The Home Economics class included subject related career lessons and improvement of teaching- learning methods. Various interesting activities and programs as a free curriculum were implemented in career exploration, students' optional program, and club activities in 38 schools. The most frequently implemented was the activity program related to food and nutrition. Further research was proposed to develop students' optional programs related to Home Economics subject, responding to their needs.

This study aims to investigate the key common topics identified and discussed in relevant literature associated with the integrative efforts among STEM disciplines. The key methodology and pedagogy were examined and the significant benefits of using the design method for STEM education were discussed. Meta-analysis was employed and qualitative approach was mainly used to synthesize the major findings and conclusions of the 33 empirical studies. The findings of this meta-analysis revealed that the types and names describing the design methods used the various terms, but the key features have reflected the similar pedagogical benefits and key characteristics. The engineering design is an effective strategic methodology and pedagogy for STEM education. In addition, the design methods show the key benefits including (1) to improve academic achievement, (2) to promote students' affective gains, (3) to facilitate collaborative learning, and (4) to explore STEM related careers and jobs. The collaborative works among STEM professions are needed to promote the benefits of using design methods for integrating STEM subjects.

This study analyzes the depictions of scientists and teachers' thoughts on the 2015 revised elementary school science authorized 3rd-4th grade textbooks from the perspective of gender equality, and suggest improvements for the 2015 elementary school science authorized 5th-6th grade textbooks as well as a 2022 revised elementary school science curriculum. The data consist of representations of scientists found in seven elementary science textbooks provided to 3rd- and 4th-grade students in 2022 as well as in-depth interviews conducted with three elementary school teachers and responses from 32 teachers in Gyeonggi-do. Of the 23 scientists depicted in the textbooks, three (13.0%) are female and 10 (43.5%) worked in the inquiry domain, which was the largest group. When the teachers were asked about their perceptions of the gender ratio of scientists in the textbooks, their answers revealed that they had lower perceptions of female scientists compared to male scientists; moreover, they had no or very little teaching experience concerning female scientists. Furthermore, the teachers' thoughts on improving the gender ratio of scientists depicted in the textbooks differed considerably by the teachers' gender. Based on these findings, it was concluded that during the process of producing textbooks, writers and members of society need to agree on the gender ratio of scientists to be represented, and a social consensus is needed to identify and introduce the achievements of previously unknown female scientists towards gender equality.

The purpose of this study is to develop and implement the Appropriate Technology Science School program (ATSS) for youth operated by the Europe-Korea Conference on Science & Technology (EKC) since 2016. The development process consisted of pre-online management meetings, online and offline tutor training, operation of ATSS for youth, and satisfaction surveys. As a result of the development, the management team selected the mission-solving theme of "Transforming village using blockchain technology" through a pre-online meeting. The contents were reorganized according to the level of the participating tutees, and various learning activities such as co-building activities, games, and plays were newly introduced and developed first, and the programs developed through tutor training were demonstrated and improved. A total of 38 tutees and tutors from 6 countries participated in the 2018 ATSS. As a result, participants showed positive satisfaction overall. Tutees showed interest in dome co-building activities and hash function calculation activities, and tutors showed interest in lectures and monopoly games related to blockchain technology. The development and of the 2018 ATSS will contribute to the improvement of expertise in the operation of the EKC ATSS in the future to the management team. It will be an opportunity for tutors to experience that high-tech science and technology have a good impact on appropriate technology for the third world and community society. In addition, Tutees will be provided with an opportunity to indirectly experience the local situation and community society through a role play on the impact of blockchain technology on African villages.
