The following research, analysis about an integral part of current elementary classroom, has been done to grasp the importance of re-organization of an elementary school classroom. For the research process 11 schools, 60 classrooms have been studied to analyze the physical elements of classroom(learning tools, equipment, etc.) to provide deeper understanding on their display, and spatial arrangement, as well as characteristic of a classroom. By looking at these analyzed elements with perspective to the grade, the number of students per class, the result turned out to be uninteresting. The observation that was made by this analysis was that there are more usages of multi-purpose desk in the classroom when there are only a few numbers of students. Also the observation could be made on the classroom wall-post. Each post had a tendency to have its defined area to be posted. The analysis showed that there are total of 24 corners can be created in the classroom, also it distinctly showed that the number of corners gets changed depending on the number of students in the classroom. The 24 corners including learning tools, equipment, and posts could be sorted to a minimum of 11 areas and a maximum of 22 areas depending on the educational purpose of the corners. The current layout of these corner and area will be the primary component that will be needed for the new coming classroom. For the future progress, depending on the system of education, the following needs to be done: (1) The installation of corners in the classroom (2) A small common-lounge area between two classrooms (3) A common-corner for each grade (4) Deeper research will be required to discuss the installation of a wide-educational area.

The problem of layup optimization of the composite laminates involves a very complex multidimensional solution space which is usually non-exhaustively explored using different heuristic computational methods such as genetic algorithms (GA). To ensure the convergence to the global optimum of the applied heuristic during the optimization process it is necessary to evaluate a lot of layup configurations. As a consequence the analysis of an individual layup configuration should be fast enough to maintain the convergence time range to an acceptable level. On the other hand the mechanical behavior analysis of composite laminates for any geometry and boundary condition is very convoluted and is performed by computational expensive numerical tools such as finite element analysis (FEA). In this respect some studies propose very fast FEA models used in layup optimization. However, the lower bound of the execution time of FEA models is determined by the global linear system solving which in some complex applications can be unacceptable. Moreover, in some situation it may be highly preferred to decrease the optimization time with the cost of a small reduction in the analysis accuracy. In this paper we explore some machine learning techniques in order to estimate the failure of a layup configuration. The estimated response can be qualitative (the configuration fails or not) or quantitative (the value of the failure factor). The procedure consists of generating a population of random observations (configurations) spread across solution space and evaluating using a FEA model. The machine learning method is then trained using this population and the trained model is then used to estimate failure in the optimization process. The results obtained are very promising as illustrated with an example where the misclassification rate of the qualitative response is smaller than 2%.

This study was planned to define the concept and the patterns of the fields for environmental education through the theory review about the fields for environmental education that were important at school environmental education for field-experience learning, and to survey the using status of the fields for environmental education and the awareness of teachers who have been teaching practically students environmental education in school through the questionnaire. The results derived from this study were as follows ; First, the use of the fields for environmental education in environmental education is necessary aspect of the importance of field-experience learning and the environmental education strategy through personalization of environment and is essential to the substantiality of school environmental education. The concept of the fields for environmental education is defined that it is used as place(space) for environmental education, is located most outdoor space, promote students the concern and consciousness about environment. The patterns of the fields for environmental education may be classified the field for nature observation learning surrounding, the fields for nature observation and field survey, the fields for visit and field trip, and the fields for experience and participation by the contents and the purpose of educational program. Second, according to the results of the teacher's awareness survey, most responded teachers gave an affirmative answer about the necessity of practical use of the fields for environmental education, and it was used mainly in special lecture, weekend, and legal holiday. Also, it was surveyed that time for using the fields was brought as the most serious obstacle by teachers. In particular, teachers preferred the environmental education fields for experience and participation above all others. Third, from the results about the using status of the fields for environmental education, school environmental education mostly have been taught in indoor classroom, school landscape(school grounds) was evaluated the most easily useful the fields for environmental education in formal lecture, because it can solve the lack of time. Also, it was proved that eco-park, stream, and river were fit for the field-experience learning with small students group.

UNESCO has continued to work in Africa, especially in the six southern sub-Saharan countries, and Asia, where international cooperation is needed. The CLC (Rwanda Community Learning Center) covered in this study aims to create a regional learning center in Rwanda and to recover local communities and provide learning environment. During the course of this study, we conducted field trips for actual planning and reviewed the current state of educational and cultural facilities that recently opened and are operated, and found implications. In consultation with the Rwandan Educational Commission, the site for CLC was decided, the building was designed, and the construction is about to start. The results of this study are as follows. First, in addition to the efforts of the activists in the village, which can be considered the smallest unit of a local community, the approach for establishing an architectural space and active education and community environment can be evaluated as a result of experimental efforts. Second, we can pay attention to the attempts to realize local communities. The bridge business is based on the multi-purposes such as early childhood education, technical education for adults, and community restoration of local residents and it reflects space and program plans for this purposes. It also reflects detailed plans such as differentiating the flow planning depending on users' time of use. Third, we can explain the characteristics of architectural planning considering local characteristics such as active use of local materials. Due to the characteristics of a developing country, there were significant considerations on maintenance, and to this end, the plan included plans for the environment and use of materials that are easily maintained. In addition, the participation of local residents in the process of establishment was suggested as a possibility to serve an educational role.

A vector space based augmented structural kinematic (VSASK) feature descriptor is proposed for human activity recognition. An action descriptor is built by integrating the structural and kinematic properties of the actor using vector space based augmented matrix representation. Using the local or global information separately may not provide sufficient action characteristics. The proposed action descriptor combines both the local (pose) and global (position and velocity) features using augmented matrix schema and thereby increases the robustness of the descriptor. A multiclass support vector machine (SVM) is used to learn each action descriptor for the corresponding activity classification and understanding. The performance of the proposed descriptor is experimentally analyzed using the Weizmann and KTH datasets. The average recognition rate for the Weizmann and KTH datasets is 100% and 99.89%, respectively. The computational time for the proposed descriptor learning is 0.003 seconds, which is an improvement of approximately 1.4% over the existing methods.

A dormitory is the most important compound space to college students who have to live with others. Also, for the students living in the boarding area, the dorm space can be the space for learning, exchanges and cultural. These Housing environment is a public space, so this is based on Universal Design. However, the 1970s-built dormitory space for the current user is narrow and not right for furniture standard. In this study, in order to compensate for these problems, the design directions are based on the previous studies - Park, Young-Soon, 2008, 'A Proposal on Dormitory Furniture Design for University Students.' Based on the previous study, the type of variable design is designed for desks, bookcases, beds, wardrobes, and other cabinets as representative household types. Furthermore, these furnitures are assembled and transformed depend on the dormitory space for single, double and four students. The furniture assembly system and arrangement module are presented in the direction of three kinds of designs. Therefore, three meaning of this study are the development of design to be used each item, the realization of custom furniture for space and presenting variable design module.
