Results of experiments conducted in university-based design studio suggests that Building information Modeling invites the adoption of a dramatically different design process, traditional design process and BIM-aided design process. Experiment method is used the actual experiment by students. In contrast to traditional design process rooted in successive refinement of abstractions and dependence on tacit knowledge, the studio BIM-aided design process depends on a complete and comprehensive date base and alterative solutions by complete analysis for helping choice of finial result. BIM viewed as provocateur of design education provides great potential for the critical analysis of how architectural design is taught. The results reflect new ways of teaching and addressing BIM methods and process in the design studio project.

This paper presents a new water-lubricated hybrid sliding bearing for a high speed and high accuracy main shaft system, along with the numerical method used for its design. The porous material for the restrictor and the restriction parameter were chosen based on the special requirements of the water-lubricated bearing. Subsequent numerical calculations give the load capacity, stiffness, and friction power of different forms of water-lubricated bearings. The pressure distribution of the water film in a 6-cavity bearing is shown, based on the results of the numerical calculations. A comparison of oil-lubricated and water-lubricated bearings shows that the latter benefits more from improved processing precision and efficiency. An analysis of the stiffness and friction power results shows that 6-cavity bearings are the preferred type, due their greater stiffness and lower friction power. The average elevated temperature was calculated and found to be satisfactory. The relevant parameters of the porous restrictor were determined by calculating the restriction rate. All these results indicate that this design for a water-lubricated bearing meets specifications for high speed and high accuracy.

Pointing to the design requirement of prestressed space grid structure being the target cable force, the pretension scheme decision analysis method is studied when there's great difference between structural actual state and the analytical model. Based on recursive formulation of cable forces, the simulative recursive system for pretension process is established from the systematic viewpoint, including four kinds of parameters, i.e., system initial value (structural initial state), system input value (tensioning control force scheme), system state parameters (influence matrix of cable forces), system output value (pretension accomplishment). The system controllability depends on the system state parameters. Based on cable force observation values, the influence matrix for system state parameters can be calculated, making the system controllable. Next, the pretension scheme decision method based on cable force observation values can be formed on the basis of iterative calculation for recursive system. In this way, the tensioning control force scheme that can meet the design requirement when next cyclic supplemental tension finished is obtained. Engineering example analysis results show that the proposed method in this paper can reduce a lot of cyclic tensioning work and meanwhile the design requirement can be met.

In this work, random homogenization analysis for the effective thermal properties of a three-dimensional composite material with unidirectional fibers is presented by combining the equivalent inclusion method with Random Factor Method (RFM). The randomness of the micro-structural morphology and constituent material properties as well as the correlation among these random parameters are completely accounted for, and stochastic effective thermal properties as thermal expansion coefficients as well as their correlation are then sought. Results from the RFM and the Monte-Carlo Method (MCM) are compared. The impact of randomness and correlation of the micro-structural parameters on the random homogenized results is revealed by two methods simultaneously, and some important conclusions are obtained.

The purpose of this study is a review of previous studies and principles of eye-tracking techniques that are actively applied in recent elementary science education. Also it proposes to utilize the direction of eye tracking techniques in elementary science education research. Recent eye-tracking technology was developed, using the infrared pupil and the corneal reflection can be safely and accurately track the eye movements of the participants. Eye tracking has the advantage of higher temporal resolution, accessibility, convenience, objectivity, stability and safety. Analysis of the previous studies, there was a difference in the study design and analysis. The workshops and seminars are needed for accurate understanding of eye-tracking method in elementary science education research. In conclusion, the eye-tracking can be utilized such as effectiveness analysis of teaching materials and media, behaviors analysis of teachers and students in a real class, cognitive strategies and attention analysis of the student, discriminating tool of various education evaluation, etc.

본 연구의 목적은 SW 교육에서 학습자들의 컴퓨팅 사고력을 신장시키기 위한 디자인 중심 모형(NDIS)의 효과를 검증하는 것이다. NDIS는 실생활의 문제를 학습자가 스스로 찾고 사용자의 요구사항을 분석하여 설계하고 구현하는 프로젝트형 학습 모형이다. 이러한 NDIS의 효과를 검증하기 위해 SW 교육 수업 경험이 있는 중급 수준의 G 교육대학교 학생을 대상으로 실험하였다. 비교반에는 전통적인 프로젝트 모형을 적용하였고, 실험반에는 CT 기반의 NDIS 모형을 적용하였다. 실험반은 비교반에 비해 높은 CT 서술형 수행평가 점수를 보였으며 이는 유의미한 차이를 보였다. 또한, 학생들은 컴퓨팅을 이용한 실생활 문제 해결에 대한 자신감과 CT 향상에 대해 긍정적인 인식을 보였다.

It became new social interest for children to have their own appropriate physical, mental, social environment as one independent identity, In these social atmosphere, new design method and standard of children's residence, education, playing environment which can fill their desire. When home and school are the first places to meet the world and learn, museum and science hall are the representing places to provide education and entertainment, especially to preschoolers, they are the prior education system. it is the most important these science halls to give children potential familiarity of science rather than direct knowledge. Also these places should be stepping stones of the process of intellectual growth as foundation stones for future science education. On this research i will provide a direction to space planning of children's science hall, extended to children' museum studying display producing of playing conception, the necessary element of children's physical, mental, social behavior development process.
