In a rapidly changing and increasingly technological society. the use of technology should not be disregarded in issues of learning algebra. The use of technology in learning algebra raises many learning and pedagogical issues. In this article, previous research on the use of technology in learning algebra is synthesized on the basis of the four issues: conceptual understanding, skills, instrumental genesis, and transparency. Finally, suggestions for future research into technological pedagogical content knowledge (TPCK) are made.

Animation tool has been made changes rapid development of animation from analog tool to digital authoring tool. Depending on the change in the status of digital authoring tools, education of digital authoring tool has brought many changes occurred in the institute and university. Digital authoring tool was insufficient for research of authoring tool due to the recognition that authoring tool is a simple tool. I try to resolve the difficulties through the analysis digital authoring tools to students studying at the university. In addition, Suggests social/cultural change of animation practitioners and effective training methods of digital authoring tools in the education of beginners and practitioners. This tool have perceptual knowledge and narrative knowledge. Since the language features and knowledge features is difficult to learn. it must be learned knowledge of computer graphics of professional level properly to learn. Then users should try to be creative within the authoring tool to produce creative results. also formed the community and to exchange information for self-development further it should form job market that authoring tool make formed through medium. So, I think that there is a need to change academically attitude to authoring tool. because this is not only the positive side but it occurs phenomenon to enslave users in authoring tool, and blind faith in the authoring tool or critical stance on software. It was a lot of pre-existing research that investigate engineering and industrial side in the authoring tool. Through this thesis, We will find social/cultural features and academic significance, and investigate that how to approach the method of education.

The purpose of this study was to examine How the exploratory activities using Excel and GSP which are exploratory software, in learning analytic geometry affected on the underachievers' analytic geometry concept development process. The subjects of 5 students who received the 8th~9th grades from their examination of the last semester, participated in a total of 7 units based on Skemp's intelligent learning model. The results of the study showed that there were two important cases found to nearly achieve the category $R_2$. One was reflective thinking could happen through exploratory software in category $R_1$. The other was the exploratory activities which could have the same effectiveness as the relational understanding in category $I_2$, as Skemp mentioned that there is a room to be achieved in the elementary level when such relational understanding is achieved.

기술혁신으로 인간과 로봇의 문자 음성형 대화가 가능한 사회가 도래하고 있다. 인간이 로봇에 정서적 반응을 나타낸다는 선행연구 결과는 로봇이 도구적 장치에서 벗어나 친밀감을 맺을 수 있는 대상이 될 수 있음을 시사하였다. 이러한 흐름을 반영하여 본 연구는 심리학에서 연구되어온 애착이론이 인간과 로봇의 관계에도 적용되는지를 분석하였다. 먼저 인간이 기계를 의인화한다는 기존의 인간-로봇 상호작용 연구를 검토하고, 인간이 타인과 관계를 맺는 방식에 대한 애착이론을 고찰하였다. 또한 인간이 기계와 정서적 관계를 맺을 수 있으나 타인과는 다른 방식으로 형성함을 선행연구를 통해 살펴보았다. 그런 다음, 애착이론을 토대로 인간과 로봇의 가능한 사회적 관계양상을 그려보았다. 마지막으로 로봇과의 소통이 일상적으로 이루어질 가까운 미래사회에 인간과 로봇의 건전한 관계형성을 위한 후속연구 주제들을 제안하였다. 본 연구는 최신 기술흐름을 반영하여 대화가 가능한 로봇을 대상으로 연구했다는 점에서 의의가 있다. 또한 인간이 타인과 관계를 맺는 방식을 바탕으로 인간이 로봇의 관계양상을 심층적으로 모색해 보았다는 점에서 함의를 지닌다.

SNS supports the formation of relationships between users in common interests and provides services allowing for clique management, sharing contents, and so on. It also has common functions such as acting as primary platforms smoothing the sharing and distribution by combination with various contents. Hence, questionnaire has been conducted to users of all of Twitter, Facebook and KakaoStory, and the factors affected by each service are presented by statistical analyses of the survey and the results are resolved by dividing them into complete and instrumental social capital. This study will be able to provide a standard for users to select SNS according to their purposes and contribute to development of new SNS or improvement of existing ones.

양록 산업의 핵심 상품은 녹용이다. 녹용은 산천초목과 같이 부드럽게 형성 되어 마치 성장하는 나무의 가지와 같이 보이다가 나중에는 계절의 변화에 맞춰 날카로운 나뭇가지처럼 변모하는 것을 보게 된다. 녹용에서 녹각으로, 계절에 따라 성장기에는 위장용의 도구로, 완숙기에는 방어용 무기로 사용된다. 녹용에는 고단위 영양분의 요소들이 있다. 뿔의 형성시기에는 호르몬의 생성마저도 정지될 정도로, 모든 기운이 모여서 뿔의 성장을 돕는다. 이런 생체적 신비감까지 지닌 녹용은 어찌 보면 귀중한 자연의 산물이다.

The purpose of the current study was to investigate the effects of explanations about physical phenomena given in non-physics textbooks on the formation of student physical conceptions. Two classes, 39 students in each, were sampled from two middle schools in Pusan, Korea, and two kinds of test tools for investigating student conceptions were developed for the study. The first test tool(a) investigated student conceptions after reading explanations about physical phenomena in non-physics textbooks, while the second(b) investigated student conceptions after reading explanations revised by physics education experts about the same physical phenomena. The two test tools were applied to each class, and for a fair invetigation, test(a) followed by test(b) was applied to one class, while test(b) followed by test(a) was applied to the other class. The results were as follows: In both classes, the students' level of understanding from explanations revised by physics education experts was significantly (p < .01) higher than that from explanations in non-physics textbooks. As such, it is feasible that false or inappropriate explanations in non-physics textbooks can cause student misconceptions. Moreover, the improper expression of physical science concepts, improper choice of scientific terms, and incorrect grammatical structures, along with the use of unsuitable examples and improper model pictures can make it difficult for students to understand physics concepts. Furthermore, differences in the terms used in physics textbook and those used in other textbooks can also confuse students' learning.

Though science and technology can understood as a part of cultural system, the relationship of science/technology with culture is often viewed as contradictory or mutually exclusive by many scholars. Therefore, in the first section of the present paper, the nature of science and technology as a cultural form is examined. Here, science is viewed as a form of symbolic culture, while technology is regarded as a form of instrumental culture. In the second section, the contradictory relationship and/or tensions between science-technological system (instrumental culture) and cultural system (symbolic culture) within a society is discussed. In the final section of this paper, 'science culture' is conceptualized as a dynamic social process in which contradictory science sub-cultures of political system(state), economic system(cooperations), civil society (including academic community of scientists and other social organizations and movements), and cultural system are supposed to be coordinated. In conclusion, establishment of 'humanized science culture' and 'democratic science-culture movement' is proposed as an alternative way of resolving contradictory relationship between cultural system and science-technological system in the modern world.

Various concepts and practices of public deliberation have been exercised over the last three decades in western countries for science and technology (ST) governance. There has been a general social consensus for the need of such new governance notwithstanding, ends and means to achieve it varied. Among various rationales, while normative and substantive perspectives are explicitly claimed in public as reasons for public engagement in ST policy making, instrumental perspectives tend to be implicitly arranged by interested parties and still affecting policy significantly. This paper therefore, examines the implications of such instrumental perspectives in public engaged ST governance. To do so, this paper analyses the discourses and practices of public deliberation for ST governance in the UK from the late 1990's until the mid 2000's. It examines the proposals made by various policy institutions and two real public deliberations- the GM Dialogue for commercialization of genetically modified crops and the Committee on Radioactive Waste Management(CoRWM)'s programme. This study finds that policy institutions tried to employ public deliberation as strategic instrument for their policy interest, which contrasted with their outwardly claimed rationales of democratic policy making and better quality in decision for ST governance.
