박규은 濟州大學 敎養學部 1976 論文集 Vol.5 No.-
SI unit is a new unit that is used world wide nowadays. We have used various unit SI unit is more preferable than the others. In many countries, SI unit is generally using in the science, industry and other fields. Some problems were extracted in this article. 1. SI unit that was regulated by the C. G. P. M is admitted internationally. So, it is desirable to admit SI unit in Korea. 2. The education about the new unit to school teachers is advisable first. 3. The use of the SI unit must be generalized by the regulation of the authories concernced.

한국과 미국의 중등학교 과학교과 과정의 비교분석 : 과학교육의 경향을 중심으로
박규은 濟州大學校 師範大學 科學敎育硏究所 1988 科學敎育 Vol.5 No.-
The aims of science education in Korea and the U. S. A. are almost all the same pattern, but the problems confornted by two countries ask different ask different types of solutions for future education. Aims of science education : 1) understanding of scientific concepts and explain natural phenomena ; 2) utilization of scientific methods for solving the problems ; 3) prepare individuals to utilize science for improving their lives and for coping with an increasing technological world ; 4) produce informed citizens prepard to deal responsibly with science-related societal issues ; Critical problems in Korea relative to science education ; 1) attempt to impose scientific explanation onto to student's current understanding, in other words, the teaching of science do not actively engage the students un study work ; 2) science teaching is not properly achieved, because admission into an advanced school is considered as an utmost peoblem in secondary school ; 3) the number of students in a classroom has too many students for adequate laboratory work ; in U. S. A.: 1) a shortage of qualified science teacher ; 2) a decline in standard test scores with respect to science ; 3) too few rules and regulations for students of science education ; Proposals to remedy the associated problems of science education : in Korea : 1) increase education budgets ; 2) improve and strance experiments and practice ; 3) reform he entrance examination for higher education ; in U. S. A.: 1) the federal governement provide strong leadership and finsncial support ; 2) increase science requirements for college asmission.

Tritiated water is one of the problem. Because the tritiated water in splitted water exiting nuclear power plant is similar to chemical and physical properties of normal water, it takes a lot of energy to separate. Although current separation process using boiling point and electronical property are developed, it is hard to use the processes in practical application because of their high-energy consumption. Herein, we increased the efficiency of tritiated water separation process using high functional polymer medium without energy consumption. In order to separate the tritiated water from the mixture, polymer medium contained carboxylic acid group is developed because the tritiated water have higher hydrogen bond ability than normal water. In addition, the structure of separation medium is fabricated as porous microbead and membrane, in order to enhance contacted surface area between tritiated water and polymeric structure.

금속철 및 산화철의 K - 흡수단 미세구조에 관한 연구
박규은,박종윤 濟州大學校 師範大學 科學敎育硏究所 1984 科學敎育 Vol.1 No.-
The K-edge absorption spectra of Fe and FeO are measured by X-ray absorption spectroscope Comparisons to theory are made for both the Fe and FeO data. We attempt to interpret origins of the spectral near-edge structure. For themetal Fe, We find agreement between the data and one-electron calculations. Peaks of near edge structure of FeO can not explain with one-electron transition model. For explanation of these peak, we find that the core-exciton and many-body effects must be taken into account. From the extended X-ray absorpticn fine structure (EXAFS), we determined distance to the nearest neighbour. The results agree with the value from the X-ray diffraction experiment.
