For this study, inquiry-based learning program was developed for promoting elementary students' scientific justification activities based on their uses of scientific evidences. The program was applied to the 5th grade science class to examine the types of evidences and major features of scientific justification activities. Analysis of the data showed that the evidences used by students were classified into knowledge-based evidence, experience-based evidence and authority-based evidence. As for students' justification features, this study reports three major cases: a case evolving evidence and justification to become more valid and logical, as inquiry activities progressed, other case maintaining less valid and illogical evidence and justification, and final case revealing passive and reluctant participation in the inquiry activities. Overall, students' participation in scientific justification process became more valid and relevant, while there were some students who were unable to make the relevant relations between evidences and claims they made. The educational implications were discussed to consider more effective ways to improve the scientific classroom environment through social knowledge construction.

This study was to investigate factors and disclose causal model of the scientific literacy competency about the motivation for science and the scientific literacy competency. The 3 grade university students and the 1 grade university students as pre-service elementary teachers were participated to questionnaire investigation. The data were analyzed by the factor analysis method and the structural equation model method, and the following results were obtained. First, the 3 grade university students and the 1 grade university students perceived the science interest factors and science usefulness factors as the motivation for science, and also revealed the scientific problem recognition factor and the scientific evidence use factor as the scientific literacy competency. Second, the science interest factor had a greater effect on the scientific problem recognition factor than the scientific evidence use factor in both the 3 grade and 1 grade university students. In the path from the science usefulness factor to the scientific problem recognition factor, the science usefulness factor of the 3 grade university students had a greater influence on the direct route to the scientific problem recognition factor than that of the 1 grade university students. In the path from the science usefulness factor to the scientific evidence use factor, the science usefulness factor of the 1 grade university students influenced more on the direct route to the scientific evidence use factor than that of the 3 grade university students.

The variety of learners include students with disabilities and general students, and an ongoing focus of inclusive education research is non-discrimination. As part of integrated education, UDL (Universal Design for Learning) for students with disabilities supports a practical approach, participation, and advancement to improve learning opportunities for all students. The purpose of this study was to examine the effects of using UDL in science classes. The dependent variables of this study were academic achievement in science, scientific attitude, and scientific motivation. In this study, the experimental groups were 9 people in the 5th grade and 11 people in 6th grade. The experimental groups were taught science class using UDL. In order to analyze the learning outcomes, the structure equation model was performed. The results of this study were as follows: First, the science achievement of learning outcomes of the science class applying UDL directly affected both scientific attitude and scientific motivation. Second, the scientific attitude of learning outcomes of the science class applying UDL directly did not affect scientific motivation. According to these results, learning outcomes for science achievement of the science class applying UDL showed that UDL affected both general students and students with disabilities. To summarize the analysis of learning outcomes, science achievement directly affected both scientific attitude and scientific motivation while scientific attitude did not affect scientific motivation. This study offered a specific implementation method for integrated education. Using the structure equation model for analyzing the effect has more significance.

현대 과학기술연구개발에서 데이터의 수집, 큐레이션, 분석, 시각화의 효율화는 과학기술발전의 중요한 요소이다. 데이터 집중연구에서 이러한 과학데이터의 가치는 절대적으로 필요하다고 할 수 있다. 과학데이터의 생산량은 기하급수적으로 증가했지만 데이터를 수집하고 배포할 수 있는 수단을 마련하는 측면에서 보면, 현재 분야별로 과학데이터의 개별적인 활용 체제만 운영되고 있어 걸음마 단계이다. 이에 본 논문에서는 국가차원의 국가 과학데이터센터 구축의 경제적 파급효과를 한국은행(2009)의 산업 연관분석을 이용하여 생산유발효과, 부가가치유발효과, 취업자유발효과 및 전 후방연쇄효과로 나누어 분석하여 국가 과학데이터센터 구축에 대한 경제적 타당성을 검증하고자 한다.

This study investigated the relationships among 'sense of humor', 'creativity', 'creativity in scientific humor', and 'perceptions of educational benefits for making scientific humor' of elementary students. To do this, fifth graders (n=42) at an elementary school and fifth graders (n=38) at gifted science education institutes in Seoul were selected. Tests for 'sense of humor', 'creativity', 'creativity in scientific humor', and 'perceptions of educational benefits for making scientific humor' were then administered. Analysis of the results revealed that all subcategories of 'sense of humor' had significantly positive relationships with all subcategories of 'creativity' except 'openness'. However, all subcategories of 'sense of humor' were not significantly correlated with all subcategories of 'creativity in scientific humor' and 'perception of educational benefits for making scientific humor'. Educational implications of these findings are discussed.

Research into scientific inquiry methods indicates that providing various types of inquiry methods can enhance students' science loaming in terms of providing students with actual science in various ways' more so than exposure to one type of inquiry method. This article develops a framework for an analysis of scientific inquiry types based on the nature of scientific enterprise. We selected three types of scientific inquiry: these were minds-on activities, hands-on activities, and experimenting. Elementary science textbooks in the 7th national science curriculum were analysed according to the following subject areas; earth science, physics, biology, and chemistry. A total of 61 teaching units from 3rd through 6th grade science textbooks were investigated. The frequencies of each type of scientific inquiry method were slightly different among four science subject areas. The most frequent type which appeared in physics and chemistry was the hands-on type, while the minds-on activity type was the most frequent type which appeared in earth science and biology.

Altmetrics is an emergent research area whereby social media is applied as a source of metrics to evaluate scientific impact. Recently, the interest in altmetrics has been growing. Traditional scientific impact evaluation indictors are based on the number of publications, citation counts and peer reviews of a researcher. As research publications were increasingly placed online, usage metrics as well as webometrics appeared. This paper explores the potential benefits of altmetrics and the deep relationship between each metrics. Firstly, we found a weak-to-medium correlation among the 11 altmetrics and visualized such correlation. Secondly, we conducted principal component analysis and exploratory factor analysis on altmetrics of social media, divided the 11 altmetrics into four feature sets, confirming the dispersion and relative concentration of altmetrics groups and developed the altmetrics evaluation model. We can use this model to evaluate the scientific impact of articles on social media.

법적시료(Forensic Evidences)로 사용되는 혈흔, 정액반, 타액반 및 모발을 DNA의 분리과정 없이 FoLT (Formamide Low Temperature) PCR법으로 DNA의 특정부위를 분석하고자 하였다. FoLT PCR법으로 3종류의 STR(Short Tandem Repeat) 좌위와 성별을 확인하는 Amelogenin gene을 PCR법으로 동시에 분석하기 위하여 formamide농도와 annealing온도를 검토한 바 최적의 formamide농도는 8%(v/v)이었고 annealing온도는 $48^{\circ}C$이었다. 그리고 1% Triton X-100을 이용하여 시료를 세척한 경우에 증폭 효율이 증가하였다. 따라서 FoLT-PCR법을 이용한 경우 DNA를 분리하기 위한 전처리없이 소량의 시료를 기존의 PCR법보다 빠른 시간내에 한번의 PCR 및 전기영동으로 HumTH01, HumTPOX, HumCSF1PO 및 Amelogenin을 동시에 분석할 수 있었다.
