Science textbooks are very important materials in order to know elementary science learning in Japan and Korea. In this research the 5th grade science textbooks in Japan and Korea are analyzed by an analyzing category. The analyzing category is consisted of knowledge and scientific inquiry. Knowledge is divided by fact, concept, and rule. Scientific inquiry is divided by problem cognition, variable control, experiment planning, observing, measuring, categorizing, inferring, data transformation, predicting, correlation, cause and effect, result, communication, which are 13 subcategories. Analyzing methods are counting the frequency of each subcategory and tabulating the data. The results of this study are: 1. The frequency of scientific inquiry appeared in Korean 5th grade science textbooks is three times more than that in Japanese textbooks. 2. In scientific inquiry category, Japanese science textbooks emphasized observing, predicting, measuring and problem cognition; Korean science textbooks emphasized experiment planning, observing and problem cognition. 3. In knowledge category, fact subcategory is mostly emphasized in both countries.

The purpose of this investigation was to examine and compare pre-service and in-service elementary school teachers' beliefs about Science-Technology-and Society (STS), particularly beliefs about the nature of science and technology, their interaction within society, and the epistemology of science. Large percentage of pre-service and in-service elementary school teachers were understood to perceive as follows : 1. they regarded the science as 〃Knowledge scheme aiming content'and technology as 'skill for solution of actual problems'. 2. they revealed themselves to perceive tat science/ technology influence our lives through new terms and ideas, that science/ technology is affected by governmental policies and that all the people concerned including scientist and technologist should participate in the course of decision making. 3. they perceived that scientist perform their studies by characteristic abilities and that the studies are affected by their religious viewpoint. Moreover, they were understood to perceive that scientific knowledge are constructed through social interaction. 4. they perceived that scientist discover and develop scientific laws by scientific methods such as verification and certification, and that those scientific laws could be changed later.

This paper examines the effects on academic achievement, scientific process skills and affective domain for elementary students learning the 'Chicken life cycle' through traditional science class versus a smart media based STEAM approach. Students designed and built a hatching jar and created a smart media content for chickens using time-lapse technology. This STEAM program was developed to improve their scientific concepts of animals over nine periods of classes using integrated education methods. The experimental study took place in the third grade of public schools in a province, with the STEAM approach applied in 2 classes (44 students) and the traditional discipline approach implemented in 2 classes (46 students). The STEAM education significantly influenced the improvement of academic achievements, basic scientific process skills and affective domain. The results suggest that this STEAM approach for teaching scientific concepts of animal life cycles has the performance in terms of knowledge, skills and affect gain achievements in elementary school students' learning when compared to a traditional approach. Moreover, the smart media based STEAM program is helpful to lead students to engage in integrated problem-solving designs and learning science and technology.

The total conductivity and oxygen permeation in (Ce1-xZrxO2)0.9(CaO)0.1 solid solutions were measure das a function of temperature and oxygen partial pressure. Empirically, σ at given x and T was expressed essentially by σ=σo2+σeo Po2-1/4, where σo2 and σeo are constant. Applying a standard defect model in which major defects are Cace", Cece' and Vo in ideal solution, we can assign σo2 as the oxide ion conductivity decreases while the electronic conductivity increases with the increase in Zr content. Using the oxide ion and electronic conductivities thus determined, the oxygen permeation flux was calculated for respective Po2 and T conditions at which the measurements were made. The calculated values were found to agree with the observed ones.

Modified inert gas condensation method was used to produce the nanocluster composites of $CuO/CeO_2$. High-resolution TEM, SEM and catalytic measurements have been used to characterize the samples and study the synergistic effect between the CuO phase and $CeO_2$(ceria) support. By varying the He pressure, the heating temperature and configuration of the heating boats inside the modified gas condensation chamber, nanoclusters of varying sizes, shapes and composition can be produced. The composition and nanostructured morphology were shown to influence the catalytic properties of the system. A copper content around 10 at% with a morphology that favors high-energy surfaces of ceria is shown to be beneficial for a high catalytic activity.

일반인들의 자연에 대한 감상과 생명과학의 이해는 오늘날 과학의 대중화에서 큰 역할을 차지하고 있다. 특히 일반인의 관심이 높은 전시와 같은 비형식 과학교육은 생태학, 동물행동학, 환경학 등 거시생물학적 분야의 내용이 주를 이루고 있다. 그렇지만 전문가의 참여 부재, 자연 현상의 피상적인 기술 등의 이유로 대중에게 효과적으로 전달되고 있지 않다. 정보와 지식은 그 자체로는 수용자가 곧바로 이해하고 받아 들일 만한 형태 및 구조를 가지지 못하다. 생명과학 지식을 일반인에게 효과적으로 전달하기 위해서는 콘텐츠를 유형별로 분류하고 콘텐츠화 하는 가공 과정이 필요하다. 주제의 선정 단계에서부터 내용의 편집 및 표현 단계까지의 일련의 과정으로서 관련 분야의 전문가인 과학자의 적극적인 역할이 강조된다. 콘텐츠화 과정은 과학적, 논리적 사고방식과 더불어 예술적 표현 및 소통 능력을 필요로 한다. 과학의 대중화를 위한 이론적 및 실천적 틀로서 통역의 개념을 제안한다.

이 연구의 목적은 초기 대표적인 과학학회의 설립과정과 그들의 활동에 대해서 살펴보는데 있다. 이를 위하여 대학 도서관 자료, 온라인 데이터베이스, 구글 학술 검색, 위키피디아 등에서 자료 검색을 실시하여 연구 대상 과학학회 설립 및 활동과 관련한 문헌들을 수집하였다. 이들 학회의 설립과 활동 분석을 위해 32편의 수집된 문헌, 선행연구 및 과학사 서적 등을 대상으로 내용 분석을 실시하였다. 연구 결과를 정리하면 다음과 같다. 과학적인 방법을 수행하기 위한 과정에서 실험의 중요성의 부각은 필연적으로 실험기기의 제작 또는 구입에 대한 비용의 증대로 귀결되었다. 따라서 과학자들은 독자적인 연구를 넘어, 공동체를 구성함으로써 최신의 정보를 교환하고, 상호 협력에 의해서 과학실험을 수행할 필요성에 직면하게 되었다. 이러한 필요성은 과학학회의 창립을 유발시키게 되었다. 초기 과학학회의 설립은 부유한 후원자가 전적으로 학회운영을 부담하는 경우, 학회 회원들이 회비를 거두어 운영하는 경우, 국가가 정부기관으로 설립하는 경우 등으로 구분할 수 있었다. 이 연구의 결과는 미래의 과학학회에 대해 시사점을 제공할 것이다.

The purpose of this study is to develop a STEAM program using technological pedagogical and content knowledge (TPACK) model to effectively utilize technology to solve the difficulties in the teaching of 'structure and function of our body' unit in the primary science curriculum and to confirm the effect on the academic achievement, creative problem solving ability and scientific interests of elementary students. The program was developed as the STEAM program of the 8th class by utilizing the construction knowledge of the TPACK model. The developed program was applied to 29 experimental group students in 5th grade. And the textbook-oriented circulatory system learning program was applied to 29 5th graders in the same school. As a result of the application of the program, the experimental group showed significant improvement over the comparison group in its creative problem solving ability and scientific interests, and the satisfaction of the class was also high. This caused a positive effect on students because the process of self-directing information about the circulatory system using smart devices, making outputs creatively using 3D printers, and presenting them through role play using produced outputs.

The purpose of this work was to study library website users' actions by tracking their behavior, determining popular content, and identifying browsing patterns and subsequent improvement of access to popular content. The study of behavior models and the use of web analytics has led to the emergence of solutions that improve the usability and functionality of the State Public Scientific-Technological Library of the Siberian Branch of the Russian Academy of Sciences (SPSTL SB RAS) website. These are: identifying user tasks as they are developed, conducting user testing to better understand the event. tracking data and collecting additional data to verify the effectiveness of the changes made. Examining data on the duration of the session and the number of visits will help determine the goals of user visits and develop new recommendations. Usability analysis and testing will make it possible to compare the data obtained using web analytics and the perception of the library site by the users themselves. Recommendations are offered to libraries on the use of data on the real behavior of the target audience of the library website to improve access to library resources and services, increase their relevance and improve information services.
