Makerspace was constructed to assist the public in creating new business, industry and market opportunities by combining their creative ideas with technology. So far, in Korea, a total of 58 makerspaces have been constructed and are running currently. Makerspaces are equipped with a variety of high-tech devices such as 3D printing technology and a laser cutter as means for transforming ideas into their prototypes. In this study, we examined users' experiences in makerspaces using online questionnaires and face-to-face interviews. We then presented motivations for using makerspace, interest in using it, concerns about using technologies, and other issues related to using makerspaces. Based on the results, we proposed three suggestions to improve users' experiences in makerspaces. These suggestions include: (1) supporting teaching and learning practices in makerspaces, (2) providing professional development opportunities for instructors in makerspaces, and (3) promoting innovative services that accommodate diverse users' needs.

This study investigated how high school students predict the rule, the sum of sequence for the concept of sequence, for the given patterns based on inductive approach using computers that provide dynamic functions and materials that are visual. Students for themselves were able to induce the formula without using the given formula in the textbook. Furthermore, this study examined how these technology and materials affect students' understanding of the concept of actual infinity for those who have the concept of the potential infinity which is the misconception of infinity in a infinity series. This study shows that students made a progress from the concept of potential infinity to that of actual infinity with technology and materials used I this study. Students also became interested in the use of computer and the visualized materials, further there was a change in their attitude toward mathematics.

Abstract: A technique to analyze the vibrations of internally fluid-filled, semi-infinite cylindrical shell which has strength members embedded in the shell wall under the axial static tension conditon is presented by using the characteristic wave propagation theory based on the transfer matrix calculated from the finite element matrices of a short module section, with spatial Laplace Tranform technique, and is verified by comparison with the measured results of the test performed on a real module model, and the effects of the embedded strength members on the vibrational response is calculated and discussed.

Combining makerspaces and library services is an innovative idea that could positively and radically change the library user experience. The Library Makerspace is able to offer users a different view of the world, and give them the opportunity to explore and imagine new possibilities which they can then create. Therefore, this study focused on analyzing real-world makerspace examples to create suggests for utilizing this trend. The roles and concepts of library makerspaces derived through this research are as follows: space for infinite creativity as social communication space, study areas, job searches, self-publishing, idea incubation, collaboration, equipment and utilization, storytelling, expert mentoring and consulting, and so on. The possibilities are endless, and allow for the development and expansion of the library.

바다는 무한한 자원의 보고이다. 미국ㆍ일본ㆍ중국 등 선진국에선 이미 바다의 개발과 보호를 위한 장기 전략을 세우고 이미 실처네 옮기고 있다. 바다를 경사하던 우리나라에서도 60년대부터 선원, 조선 수출 등 바다관련산업이 등장하여 우리나라 경제발전의 견인차 역할을 해왔다. 당장 투자효과가 나지 않더라도 해양기술 개발과 축적을 위해 과감한 투자가 앞서야 하겠다.

This study suggested that the concept of creative zone raised by the national interest of the 'Creation' should be extended in public libraries. The concept of creative zone in public libraries was analyzed on the basis of 'Con-creative structure ontology' by Rombach. As we understand a creator and creation as the relation of 'subject'-'object', The current concept of 'Creation' dilutes the possibility of 'Autogenese' that all beings as a subject possess. But 'Con-creative Structure' describes the process of 'Autogenese' through sharing and mutual communication of all beings. The formation process of Con-creative Structure corresponds to the philosophy of the library that supports the self-growth through communication and sharing. 'Co-working Space' is more suitable for the substantive image of Con-creativity than 'Makerspace'. Therefore, this study analyzed circumstances of creative zone in public libraries and Co-working Space in business areas and provided the conceptive and substantive modeling for Co-working Space in public libraries.

This paper aims to compare and contrast Kierkegaard and Turing, whose birth dates were one hundred years apart, analyzing them from the perspective of the limit. The model of analysis is two concentric circles and movement in them and on the boundary of outer circle. In the model, Kierkegaard's existential stages have 1:1 correspondences: aesthetic stage, ethical stage, religious stage A and religious stage B correspond to inside of the inner circle, outside of the inner circle, the boundary of the outer circle and the outside of the outer circle, respectively. This paper claims that Turing belongs to inside of the outer circle and moves to the center while Kierkegaard belongs to outside of the outer circle and moves to the infinity. Both of them have movement of potential infinity but their directions are opposite.

Dynamic extinction of solid propellants subjected to rapid pressure drop was studied with the aid of energy equation of condensed phase and flame model in gas phase. It is found that the total residence time($\tau_\gamma$) which measures the residing time of fuel in the reaction zone may play a crucial role in determining the dynamic response of the combustuion to extinction. Residence time was modeled by various combinations of diffusion and chemocal kinetic time scale. Effect of pressure history coupled with chamber volume on the extinction response was also performed and was found that dynamic extinction is more susceptible in a confined chamber than in open geometry. And, dynamic extinction was revealed to be affected profoundly by diffysion time scale rather than chemical kinetic time scale.

정보화된 미래사회를 준비하기 위하여, 우리나라에서는 실과의 한 영역과 학교재량시간을 통하여 컴퓨터 교육을 하고 있다. 그러나 실과 교육과정은 지나치게 기능 위주의 내용으로 되어있고, 학교 재량시간을 이용한 컴퓨터 교육에서는 타자연습이나 컴퓨터 활용교육만을 강조하고 있다. 이러한 교육은 컴퓨터와 친숙해지는 데는 도움을 줄 수 있지만, 고차원적인 사고력을 지닌 학생을 교육하는 데는 도움이 되지 못한다. 특별히 컴퓨터의 무한한 사용 가능성을 이용하여 창의적 문제 해결력을 기르는 교육은 매우 필요하다 하겠다. 이러한 문제를 해결하기 위하여 문제 해결 능력 교육, 즉 문제 상황이 주어지고 이것을 해결하는 프로그래밍 교육이 매우 유용하나, 지금까지의 프로그래밍 교육은 지나치게 언어 기술교육에 초점을 두고, 단순 반복과 암기, 아동의 발달단계를 고려하지 않음으로 인해 오히려 창의성을 해치고 학습의 흥미도를 저하시켜왔다. 이에 본 연구에서는 학생들 수준에 맞춰 구체적인 결과물이 보이고, 쉽고 흥미롭게 학습할 수 있는 프로그래밍 교육과정을 개발하기 위해 'LED 소자를 이용한 프로그래밍 교육 방안'을 설계하였다. 본 연구를 통하여서 초등학교 학생들이 쉽고 재미있게 프로그래밍에 접근하고, 고차원적인 문제 해결력을 기르는 컴퓨터 교육과정의 한 모델을 제시하였다.

This study explores the concepts and programs of 'makerspaces' at public libraries. It examines the extended and sustainable service outreach strategies of 14 Korean public libraries whose makerspaces were identified as "infinite imagination spaces." Through interviews with staff members, the study identifies the needs, effects, limitations, and future direction of makerspaces. The study also evaluates the development, types, funding sources, and outcomes of makerspaces in public libraries through related literature reviews and case studies. The study's findings suggest that strategies with stable and varied funding, staffing, and training are crucial to fostering makerspaces that not only become communal gathering spots, but also become gateways to technological tinkering that 'make' spaces for community archives.
