  • Creativity is an ever-increasing research area related to fashion design, namely the documentation and dissemination of creative scholarship. The purpose of this project is to apply creative bridge or creative leap theory to the development of an existing designer's garment collection using the creative design process of an architect. A single case study design was used to investigate the phenomenon of design process creative leap using a direct observation. Results indicate the difficult challenge of producing new and individualized silhouettes for the marketability of clothing, it is apparent that new methods of fostering creativity in designers through non-traditional approaches would benefit the education of apparel designers. Through targeted design practice, educators and practitioners can apply the principles of scientific inquiry into design processes to solve a problem, address a challenge, or create based on personal inspirations.

  • Ceramic based nanocomposite, in which nano-sized ceramics and metals were dispersed within matrix grains and/or at grain boundaries, were successfully fabricated in the ceramic/cerarnic and ceramic/metal composite systems such as $Al_2O_3$/SiC, $Al_2O_3$/$Si_3N_4$, MgO/SiC, mullite/SiC, $Si_3N_4/SiC, $Si_3N_4$/B, $Al_2O_3$/W, $Al_2O_3$/Mo, $Al_2O_3$/Ni and $ZrO_2$/Mo systems. In these systems, the ceramiclceramic composites were fabricated from homogeneously mixed powders, powders with thin coatings of the second phases and amorphous precursor composite powders by usual powder metallurgical methods. The ceramiclmetal nanocomposites were prepared by combination of H2 reduction of metal oxides in the early stage of sinterings and usual powder metallurgical processes. The transmission electron microscopic observation for the $Al_2O_3$/SiC nanocomposite indicated that the second phases less than 70nm were mainly located within matrix grains and the larger particles were dispersed at the grain boundaries. The similar observation was also identified for other cerarnic/ceramic and ceramiclmetal nanocornposites. The striking findings in these nanocomposites were that mechanical properties were significantly improved by the nano-sized dispersion from 5 to 10 vol% even at high temperatures. For example, the improvement in hcture strength by 2 to 5 times and in creep resistance by 2 to 4 orders was observed not only for the ceramidceramic nanocomposites but also for the ceramiclmetal nanocomposites with only 5~01%se cond phase. The newly developed silicon nitride/boron nitride nanocomposites, in which nano-sized hexagonal BN particulates with low Young's modulus and fracture strength were dispersed mainly within matrix grains, gave also the strong improvement in fracture strength and thermal shock fracture resistance. In presentation, the process-rnicro/nanostructure-properties relationship will be presented in detail. The special emphasis will be placed on the understanding of the roles of nano-sized dispersions on mechanical properties.

  • The most of elementary school science textbook contents are composed of observation and experiment activities. When students study natural phenomena, observation and experiment are st rongly emphasized to improve understanding of scientific concepts and inquiry abilities. The purpose of this study is deep understanding about experimental science classes. This ethnographic study is conducted by observations of experimental science classes in natural setting and interviews of teachers, students of the 5th grade. The conclusions of this study are as follows: First, the general process of the elementary science experimental classes is 'identifying learning purposes -1 planning experiments -1 predicting the results -1 experimenting-t summarizing the results.' The experiments are conducted by group activities and the teachers conceived that the me st difficult step considered by students is 'planning experiments'. Second, students like hands-on activities, but they feel difficulty on less guided experiments. Students perform results oriented-activities. Third, in group activities, students prefer to work with the same gender or collaborative peers.

  • 이 연구는 과학교육에서 의사소통을 위해 글쓰기와 논의를 활용한 논의-기반 모델링 전략의 개발을 목적으로 하였다. 논의-기반 모델링 전략은 모델링의 목적인 의사소통을 위해 자신이 만든 모델을 논의와 글쓰기를 통해 과학적 언어를 사용하여 스스로 정리하거나 표현하고, 다른 사람의 의견을 듣고 교환하는 과정을 통해 모델을 평가하고 수정하는 일련의 과정을 의미한다. 이 전략은 과학교육에서 모델링에 어려움을 느끼는 학생과 교사를 지원하기 위한 것으로 다음 네 가지 요소의 발달에 초점을 맞추었다. 첫째 여러 문제 상황을 관찰하여 문제를 연관지어 인식하는 문제인식이다. 둘째는 과학적 설명을 위해 충분한 과학개념을 구조화하여 제시하는 과학개념 구조화이며, 셋째는 주장에 대해 적절한 표상을 증거로 제시하는 주장-증거 적절성이다. 마지막은 증거제시에서 다양한 표상의 사용과 이 표상들을 전환하고 통합하는 다중표상 지수이다. 이 네 가지 요소의 발달을 위해 세 가지 stage를 구성하였다. '인지 과정'은 다중표상에 대한 이해를 위한 것이고, '해석 과정'은 다중표상 활동을 통해 증거 제시의 중요성을 인식하는 것이며, '적용 과정'은 학생들이 논의-기반 모델링을 직접 접해보는 것이다. 이 적용 과정에서는 질문 또는 문제 만들기-실험 설계 및 수행하기-관찰 통한 조사하기-자료의 분석 및 해석하기-임시 모델 설계하기-논의하기-되돌아보기-모델 평가하기-모델 수정하기의 아홉 개의 단계로 이루어진다. 논의-기반 모델링 전략은 학생들이 자신이 설계한 임시모델을 다른 사람과 공유하기 위해 증거를 바탕으로 발표하고 반박하는 논의과정을 통해 증거 제시의 필요성을 인식할 수 있다. 논의과정 후 학생들은 주장과 증거를 다중표상으로 나타내는 것에 대해 되돌아보는 과정을 거치면서 주장-증거 적절성을 높이게 된다. 또한 모델을 평가하기 위한 기준을 만들고, 이를 바탕으로 자신의 모둠이나 다른 모둠의 모델을 평가하고 그 결과를 피드백 받으면서 수정하게 된다. 이러한 일련의 과정을 거치면서 관찰한 자연세계의 현상에 대한 자신의 설명체계를 만듦으로써 과학적 지식을 형성할 수 있는 기회를 제공받을 수 있다.

  • Polymer materials have a lot of merits including the low cost and the easiness of forming. For these reasons they are widely using at many manufacturing industries. Microcellular foaming process appeared at MIT in 1980s to save a quantity of material and increase mechanical properties. There are many process variables in appling microcellular foaming process to the conventional injection molding process. They can be solved by using Axiomatic Design Method which is very useful design method for designing a new product. Its main character is scientific and analytical. The information about the thickness of cavity plays an important role in making an effective foam. The goal of this research is to design mold system for advance of foaming magnitude with axiomatic design method. There is a relation between the change of cavitys thickness and foaming magnitude made after inserting a gas. R/t is a conception that indicate proportion between radius and thickness of cavity in mold system. By means of SEM observation of side surface of cavity sample, foaming magnitude of polymer in microcellular foaming process is decreasing gradually as the value of R/t is increasing. In this paper, an advanced mold system was presented by mapping the relation between functional requirements and design parameters.

  • In Korea, previous survey in science education mainly dealt with Quantitative variables. Qualitative ethnographic observation can bring deeper understanding of the context of school lesson and it's feature. The purpose of this study was to develop qualitative understanding about the learning experiences provided in middle school and students' responses to them through observation and interview and to investigate it from a constructivist perspective. Six lessons of the 9th grade were observed and recorded on the video tape. The topics of the lessons were potential energy, kinetic energy and conservation of mechanical energy. We had also unstructured interview with the teacher and three groups of students. The teacher's deductive explanation starting from scientific definition and quantitative problem solving using formula were the main features of the classroom lectures. The video - watching lesson was taking the role of a break rather than being seen as a useful tool for science learning and teaching by both students and the teacher. The teacher's perception about the lab experiment was not supported by the responses from the students. The teacher and students preferred problem-book to textbook for their teaching and learning. From a constructivist's perspective, however the teacher seemed to have intention of introducing daily life context, he couldn't unfold it to main context of the lessons. Students were so accustomed to passive learning that they did not express directly their complaint about their learning and did not participate in planing and controling their learning. The teacher and the students believed the scientific knowledge came from an exact experiment. There was a cooperation to seek right answer rather than a social process of making sense of knowledge. In conclusion, the observed science lessons of a middle school showed typical cross section of teacher - centered, passive learning environment, which is far from constructivist perspective.

  • The article highlights the problems of the digitalization of the educational process, which affect the pedagogical cluster and are of a psychological nature. The authors investigate the transformational changes in education in general and the individual beliefs of each subject of the educational process, caused by both the change in the format of learning (distance, mixed), and the use of new technologies (digital, communication). The purpose of the article is to identify the strategic trend of the educational process, which is a synergistic combination of pedagogical methodology and psychological practice and avoiding dialectical opposition of these components of the educational space. At the same time, it should be noted that the introduction of digital technologies in the educational process allows for short-term difficulties, which is a usual phenomenon for innovations in the educational sphere. Consequently, there is a need to differentiate the fundamental problems and temporary shortcomings that are inherent in the new format of learning (pedagogical features). Based on the awareness of this classification, it is necessary to develop psychological techniques that will prevent a negative reaction to the new models of learning and contribute to a painless moral and spiritual adaptation to the realities of the present (psychological characteristics). The methods used in the study are divided into two main groups: general-scientific, which investigates the pedagogical component (synergetic, analysis, structural and typological methods), and general-scientific, which are characterized by psychological direction (dialectics, observation, and comparative analysis). With the help of methods disclosed psychological and pedagogical features of the process of digitalization of education in a mixed learning environment. The result of the study is to develop and carry out methodological constants that will contribute to the synergy for the new pedagogical components (digital technology) and the psychological disposition to their proper use (awareness of the effectiveness of new technologies). So, the digitalization of education has demonstrated its relevance and effectiveness in the pedagogical dimension in the organization of blended and distance learning under the constraints of the COVID-19 pandemic. The task of the psychological cluster is to substantiate the positive aspects of the digitalization of the educational process.
