The purpose of this study was to develop science essay writing activities for developing elementary pre-service teacher's scientific thinking ability and scientific emotion and to analyze its effects. For the study, 60 first grade students attending teacher training institutes in the G region of Korea were selected. All 60 elementary pre-service teachers were students who selected a liberal arts lecture related to 'science inquiry'. As a result of the study, we confirmed that the preliminary teacher uses the scientific method of 'induction' in the article related to scientific thinking and the description related to the past time, agency, and purpose of the story is included in the essay related to scientific emotion. In addition, it was confirmed that elementary school teachers' writing ability was improved as the writing was repeated, and that the image of 'science' changed positively in many areas. This study suggests that a various and interesting scientific inquiry activities are needed to improve the science writing skills.

The target of design is a harmony between Beauty and Usefulness. Design is a result from representation of visual language by designer's creative thinking system. also, As an ill-defined problem cannot be described completely. and subjectively interpret depend on the situation, it is very difficult to present a theoretical standard. There have been many Design Sciences researches in recent years. such as Rule Based Design, Parametric Design, Replacement Design, Analogy Design, Metaphor Design, Genetic Algorithm. but Objective research is still unsatisfactory condition to investigate true nature about Design. At this point, It is very important to formulating about meaning of Design Language and Thinking. This study will define about that, and based on this definition, Lay out a logical basis for Treatment design variable and materialization of process by "Elements", "Relationship", "Schema". ultimately it look forward to provide a framework and minimize the complexity about Design Thinking.

XR(가상 및 확장현실)에서의 리얼타임 그래픽은 조명이 제 역할을 하지 못하면 인물이 공간감이 느껴지지 않거나 스킨톤이 맞지 않아 이질감을 초래한다. 본 논문에서는 Art-Net 시스템을 활용하여 실제 조명과 가상조명에서의 배경 및 인물의 컬러를 동기화하는 방법을 제안하였다. 제안된 Art-Net 시스템을 통해 인물의 공간감을 향상 시킬 수 있을 뿐만 아니라 보는 이의 몰입감을 높였다.

This study started from the need to improve one of shortcomings of synthetic PVAc adhesives - potential physical harm and environmental hazards to the workers or their users. As a matter of fact, PVAc adhesives are currently mainly used because of their convenience and economy for the production of woodcrafts. The purpose of this study was to develop natural adhesives through research on natural adhesives in step with the current increase of societal attention to environmental friendliness and rapid surge in their demand in the face of such problems. So, the study attempted research on the bases to develop natural adhesives for woodcraft, using cellulose extracts from wood - natural adhesive material. The findings of the study were as follows. Firstly, natural adhesives showed the improved effect in the field of adhesive strength, a basic physical property by 0.2 - 4 times compared with the existing materials and the study confirmed they had the similar or stable pH value. Besides, they had good reversibility, demonstrating their basic physical property as a natural adhesive for woodcraft. While, their durability to ultraviolet ray degradation also showed an excellent result value being better by 1.5 - 8.5 times than the existing materials. The study expects natural adhesives with improved and better performances compared with the existing materials could be developed, if further research on adhesive strength, antibiosis, conservative property were to continue by developing refinery technology for cellulose extracts from wood and rendering the functionality to them.

Service Design Platform which has been developing under the sponsorship of the Ministry of Knowledge Economy is aimed at facilitating service design consultancy to carry out service design projects smoothly online. In the development process in order to verify and improve the usability of the platform, heuristic evaluations by usability experts along with usability test done by user participation are required. This study was conducted for the purpose of deriving appropriate evaluation areas and detailed evaluation indices prior to carrying out the heuristic evaluation. For the study, first, the concept of the service design platform was identified and the features of its component were analyzed. Second, based on literature study of standards which are related to usability evaluation indices, usability evaluation areas and indices were analyzed. Third, in order to establish and verify evaluation areas and indices which are appropriate for the evaluation, Delphi survey was conducted and its validity was verified. Through this study, evaluation indices with 4 evaluation areas and 45 detailed items were derived. Derived evaluation indices was made in the form of checklist and will be utilized for heuristic evaluation by usability experts.

본 논문에서는 수학교육용 소프트웨어에서 확률적 현상을 경험한 이후 과학 그래프 해석에 있어 확률론적 관점을 도입하여 해석하는 학습자의 관점의 변화를 제시한다. 이 연구에서 11명의 고등학교 1학년 학생은 수학교육용 소프트웨어인 지오지브라(GeoGebra)를 활용하여 학습자가 평면 상에서 수직선이나 반원 위에 점을 찍는 활동을 통하여 기하학적 확률을 경험하였으며 이와 같은 경험을 토대로 물의 상평형 그래프를 해석하였다. 물의 상평형 그래프에 나타나는 얼음(고체), 물(액체), 수증기(기체)의 상태 변화에 대하여 각 상태가 나타나는 온도-압력의 영역 간의 경계에 대하여 학습자는 기하학적 확률을 적용하여 해석하려고 하였으나 경계선 위의 온도-압력의 물의 미시적 구조를 표현하는 과정에서 4명의 학생만 확률론적 관점으로 해석하고 그렇지 못한 학생들은 상태의 공존을 물질적 관점이나 과정적 관점으로 이해하였다.

Recently, the government as part of the creation of science for science education policies promoting the activation of the Science Museum. However the lack of infrastructure, budget and human resources are a reality that a lot of difficulties. In past, A field trip of Science Museum was a place of curiosity of youth. However, modern Science Museum has to competition with the online games and theme park in order to achieve the two goals of scientific experience and education, which it needs change display device is required. Looking at the cases of advanced foreign Science Museum is not merely a head of science education experience as a cultural space, provide relaxation and entertainment, and life science area in addition to a variety of genres such as art and fashion exhibits are planning to combine. In this study, the current uniform description panel of exhibition device described in the written text replaced with the digilog book with the age and grade of the visitors by providing a tailored service for scientific knowledge and intellectual curiosity induced measures can claim the satisfaction of visitors is proposed.
