This study aims to analyze how the history of mathematics is used in Chinese mathematics textbooks. As a framework for analysis, we categorized nine types of using the history of mathematics in textbooks. We analyzed 18 mathematics textbooks for Chinese elementary and middle schools. As a result, we found that various types of using the history of mathematics were adopted in Chinese textbooks except for explorations of mathematical errors in history. We also noticed three characteristics: preference to using for motivation and reading matters in elementary school levels, high frequencies of using problems from traditional mathematical books and origins of mathematical concepts or symbols, and emphasis on ethnic superiority through the Chinese traditional mathematics. Based on the results of analysis, we discussed and induced some implications for using the history in our mathematics textbooks.

The relationship between past liver disease history and the risk of primary liver cancer was analyzed in a hospital-based case-control study conducted in Seoul on 165 patients with histologically or serologically confirmed hepatocellular carcinoma and individually age- and sex-matched 165 controls in hospital for ophthalmologic, otologic, or nasopharyngeal problems. Significant association were observed for liver deseases occurring 5 or more years before liver cancer diagnosis [OR,4.9;95% confidence interval (CI), $1.6{\sim}14.0$) and family history of liver disease(OR, 9.0;95% CI, $2.1{\sim}38.8$). These associations were not appreciably modified by allowance for major identified potential confounding factors. From these results, it is possible to speculate that liver cell injuries caused by various factors might be a common pathway to developing primary liver carcinoma. Considering the significant effect of family history of liver diseases on PLCA risk after adjusting past liver disease history, there might be genetic susceptibility in the carcinogenic mechanism of liver cancer. Further investigations are needed to clarify the effect of family history of liver disease on PLCA risk.

본 연구의 목적은 자연사 및 자연사박물관에 대한 학생, 교사, 학부모들의 인식을 연구하는 것이다. 이를 위해 첫째, 자연사와 자연사박물관에 대한 개념의 특징을 알아보기 위해 인지도, 친숙도, 연상되는 것, 느낌, 포함될 분야 등을 알아보고, 둘째 개념의 접촉통로를 알아보기 위해 접촉매체, 교육경험, 관람경험 등을 조사한 후 마지막으로 관심도를 알아보기 위해 학습에 대한 흥미, 관람에 대한 흥미 등을 조사하였다. 그 결과 첫째, 사람들은 자연이나 환경에 대한 관심이 의외로 높지 않았다. 둘째, 사람들에게 자연사와 자연사박물관은 둘 다 들어본 경험이 드문 것은 아니지만, 친숙한 개념은 아니었다. 셋째, 사람들은 자연사와 자연사박물관이란 말을 들었을 때 공룡을 가장 먼저 연상했고, 자연사란 말은 '낯설지만 관심 있고 신비로운' 느낌을 주며, 자연사박물관은 '낯설지만 교육적이고 관심을 갖게 하는' 대상으로 지각하였다. 넷째, 자연사와 자연사박물관이란 말은 TV를 통해 가장 많이 접했다. 다섯째, 대부분의 사람들은 자연사를 학교에서 배운적이 없었지만, 배워보고 싶은 요구가 높았고, 마찬가지로 자연사박물관을 경험한 사람이 드물었지만, 관람해 보고 싶은 요구는 높았다.

The 19th CPC National Congress has a key historical significance in the development of China's constitution. It will also play a decisive role in the history of the seventy years'constitutional change in New China. XiJinping's new socialist thought with Chinese characteristics established in the report of 19th CPC National Congress will be written in the preface of the March 2018 National People's Congress's constitutional amendment. The fifth revision of 1982 Constitution will touch on many issues such as the leadership of the CPC into the constitution, the abolition of the tenure of the president, the constitutional oath system, and the reform of the national supervisory system. In addition, the constitutionality review system, the establishment of the National Security Council, the constitutional status of socialist public property and private property and the adjustment of major economic system has become a hot topic in the theory field. In the history node towards a socialist country ruled by law, the theory and practice of the China indeed have the academic ideas, value position and path model differences, which will delay the Chinese constitutional development, but also is the necessary pain in the process of moving towards the rule of law in China. Indeed, how to the development and where to go in the future of Chinese constitutionalism itself has sample value, which deserves rational attention and in-depth inquiry from Chinese and Western academics.

Science has developed along with human society and history. In today's society ruled by pluralism, an educational approach using the historical materials which represent their own cultures will make science education more effective. The purpose of this study was to search for the meaning of science education related with a history of science, and to suggest the possibility for science education based on Korean history of science. The conclusions of this study is below: (1) The history of science is useful to teaching science in K-12 setting. That is because it was helpful to make a scientific concept and to invite student's interest about learning science. Moreover, it was most suitable to teach the nature of science as well as the relation between science and society. (2) A model which consists of 15 types of science education materials using Korean history was suggested. This model plays a potential role as a R&D framework of developing teaching & learning materials based on the history of Korean Science.

Extremely metal-poor (EMP; [Fe/H] < -3.0) stars are thought to be genuine second-generation of stars because they were born from relatively pristine gas chemically enriched by one or two supernovae. So, the EMP stars presumably originated from outside the Milky Way (MW) are important tracers for the early chemical evolution and assembly history of the MW. In this study, we present the preliminary results on the early assembly history of the MW inferred by associating the dynamical properties of our EMP stars with those of known substructures in the MW. We also explore the star formation history of the progenitor galaxies of our EMP stars by investigating the elemental abundances of the EMP stars associated with the substructure.

본 연구는 전근대 우리 땅을 밟은 외국인들인 벨테브레와 하멜을 역사 수업에 어떻게 활용할 수 있는지에 대한 연구이다. 벨테브레와 하멜은 모두 네덜란드 사람이며, 조선에 먼저 표착한 이는 벨테브레였다. 네덜란드 동인도회사 소속의 선원이었던 벨테브레는 1627년 제주도에 상륙하였고, 이후 귀국하지 않고 '박연'이라는 이름으로 조선에 귀화하여 조선에 귀화한 최초의 서양인이 되었다. 박연은 당시 북벌정책을 실시하고 있던 조선에서 훈련도감에 근무하며 조선의 병기개발 및 개량에 커다란 역할을 다하였다. 네덜란드 동인도회사의 무역선 포수였던 하멜은 1653년 조선에 표류하여 13년 동안 여러 계층의 사람들과 접촉했고, 여러 지역으로 끌려 다니면서 당시 조선의 풍물과 풍속에 대한 사정을 자세히 관찰할 수 있었다. 교류사 학습은 세계사의 종합적인 이해에도 도움을 준다. 학생들은 서양사와 동아시아사, 한국사를 구분해서 배우기 때문에 세계 역사의 종합적인 흐름이나 시대별 서양과 동양의 모습에 대한 종합적인 이해가 힘들 수 있다. 전근대의 동서교류와 관련된 인물들에 대해 학습하는 것은 학생들로 하여금 서양과 동양의 역사를 세계 역사의 흐름 안에서 같이 연결 지어 이해할 수 있도록 해줄 것이다.

The purpose of this study was to explore characteristics of natural history museum exhibits from the viewpoint of science education. A total of ninety exhibits for this study were examined in national science museums of Korea and Japan. Exhibits of Tokyo national science museum were again divided into two groups: the old and traditional types, and the new and renovated ones. Even though analyzing data was not undertaken through quantitative statistical process, the interpretation of the data was valid enough to fulfill the purpose of the research. While there were clear changes and differences between the old and the new types of exhibits in Tokyo national science museum, the old part of Tokyo museum was similar to one in Korea. Based on analyzing the new types of Tokyo museum, the current movement in the field of natural history museums of Korea explicitly has toward utilizing more science education concepts and ideas.

In this expository paper, we present an abridged report on the max-plus eigenspaces of max-plus matrices with its brief history. At the end of our work, a number of examples are presented with maple codes, and then we make a claim from the observation of these examples, which is on the euclidean dimension of the max-plus eigenspaces of strongly definite matrices.
