Silicon (Si) is the second most abundant element in the crust and consists of three stable isotopes, 28Si (92.23%), 29Si (4.67%), and 30Si (3.10%). Si isotopes are widely studied worldwide as a proxy for the biogeochemical cycle of Si to reconstruct the paleoenvironment and paleoclimate. However, in Korea, there have been no studies on biogenic silica using Si isotopes. In this study, we carried out Si isotope measurements of giant diatoms, summarizing the previously reported alkali fusion methods and establishing the best Si separation method for biogenic silica. Samples were completely digested using alkali fusion at high temperatures, effectively separating Si using an AG® 50W-X8 cation exchange resin. To evaluate the precision and accuracy of our measurements, Si isotope standard material (NBS-28) and USGS reference materials (AGV-2, GSP-2, BHVO-2) were analyzed. The results are in excellent agreement with the reported values within the acceptable error. The Si isotope measurement method developed in this study is expected to help in understanding the paleoclimate and paleoenvironment by tracing the Si cycle.

The purpose of this study is to analyze the invention-related content of foreign science curricula and investigate the perception of science educators about the degree of relevance between science curriculum and invention. For the analysis of foreign science curricula, we investigated the programs of 10 nations, including the US, Canada, UK, Japan, Australia, Singapore, New Zealand, France, Finland and China. To analyze the relevance between Korean science curriculum and invention, we examined common topics such as science, integrated science, and science inquiry experiment, and investigated that the elements related to invention education were included in each 'achievement standard' and 'teaching and evaluation methods'. Science educators including science teachers were asked to evaluate the degree of relevance of invention education. The results were as follows. First, science curricula in many countries contained invention-related content. Second, science educators recognized that invention education was related to science curriculum, but the systematic connection was insufficient. Third, because it is mainly limited to the results of designing and device design, they recognized that the relevance of invention education, which focuses on various processes such as problem design, inventive techniques and intellectual property, was not revealed. Therefore, it is necessary to be process-oriented when developing invention education teaching-learning methods and related materials in science education for the future.

Many kinds of teaching methods have been used to instruct ethical issues that arise in the field of science and technology. However, few teaching methods of bioethics have been validated by ethical theories, or justified based on practical utility in bioethics teaching. The aim of this article is to suggest teaching methods of bioethics that are appropriate for ethical theories and socio-scientific issues related to biological sciences in secondary schools. In the article, the teaching methods are classified into three types of ethical theories and into three types of socio-scientific issues in biological sciences. The characteristics of nine teaching/learning methods are then described in terms of appropriate bioethical issues or contexts, and ethical theories or principles.

최근 우리나라는 다양한 매체를 활용한 재난경보 전달 시스템을 운영하고 있다. 하지만 시스템 연동 및 자동화에 있어 많은 문제점을 가지고 있다. 본 논문은 이와 같은 문제를 해결하기 위해 우리나라와 미국의 관련 규정을 조사 분석한다. 미국은 능동적 재난방송을 법으로 규정하지 않고, 수동적 재난방송만 연방정부 규칙으로 정한다. 이러한 규칙은 시스템 간의 연동을 위한 표준, 수신기 재난경보 수신을 위한 요구사항 등 기술적인 규정을 포함하고 있다. 반면 국내 규정은 주로 관련 인적 행정 조직의 운영에 초점을 맞추고 있다. 향후 다양한 매체를 통해 고도화된 재난방송을 위해, 우리나라도 이러한 기술적인 요구사항을 법령에서 규정해야 한다. 본 논문에서 분석한 미국 사례 분석은 ATSC 3.0 재난방송의 기술적 규칙 작성에 많은 도움을 줄 것으로 기대한다.

국가연구개발사업은 현재 각 부처 별 다수의 법률에 근거하여 운영되고 있다. 일선 연구자 입장에서의 행정 절차 상 불편함과 국가 연구개발 중장기 계획 상 일관성의 부족이 문제로 지적되었다. 이에 수년 전부터 국가연구개발사업에 공통적으로 적용할 법률의 필요성이 제기되었으나, 실제로 제정되지는 않았다. 이 논문에서는 여러 정부 부처를 아우르는 국가연구개발사업 법률 제정 시 사안 별로 공통 적용을 해야 할 것과 그렇게 하지 말아야 할 것을 구별한다. 관련 정부 조직 개편에 있어서는 각 정부 부처들의 국가연구개발사업 기획 기능 강화와 국가과학기술자문회의 및 과학기술혁신본부의 정부 부처 간 사업 조정 기능 강화, 그리고 전문기관의 사업 관리 기능 전담을 법적으로 규정할 것을 주장한다. 국가연구개발 중장기 계획의 일관성 제고가 이 법률안의 취지에 포함되나, 중장기 계획은 지속적으로 제 개정이 필요하기 때문에 법적으로는 근거 조항만 두고, 국가과학기술자문회의가 범부처 중장기 계획을 수립하도록 할 것을 주장한다. 또한 부처 간 사업 조정 시 유사 및 중복 사업이 아닌 경우, 사업이 축소되지 않고 각 부처가 개별적으로 진행할 수 있는 근거 조항이 필요함을 주장한다.

Supercomputers have played an important role in various fields such as science, industry, national security and solutions for social issues, and their demand is increasing significantly as their use is strengthened in areas using big data and AI. Recently, competition for global exascale system development is accelerating based on various architectures, and the era of exascale computing is expected to come in the near future. However, the foundation of the domestic supercomputing ecosystem was lost due to the decline of the server industry in the past, and although the related law was enacted to supplement and foster it, it has not been able to perform its function smoothly. Therefore, this article examines the problems in the current legal system through the analysis of the relevant legal system and the status of the supercomputing ecosystem, and suggests improvements so that the relevant legal system, which can accommodate the reinforcement of the role of the government·national center·professional center, support for industries, promotion of commercialization of research results, and flexibility of government promotion policies, can prepare the basis for the promotion of the supercomputing R&D project.
