The current process of weapon system R&D has lots of problems that the phase is complex, the concept of integration and/or connection of related data is laked and don't be digitalized. To solve these problems we should establish the R&D CALS system and to do this, analysis the R&D process is necessary. In this paper, We suggested weapon system R&D CALS concept and model, and analysed R&D process with ARIS Toolset and proposed the new R＆D process and operation scenarios with CALS concept.

Next Generation High Speed Train having a distributed electrical motor system has just been developing to aim the experimental maximum speed at 400km/h since August, 2007. This project is in stage of concept design and so, it needs to take some review and analysis the characteristics of suspensions on the view of concept design. A train dynamic modeling is modified with the one car model presented in the previous conference and it was extended to 6cars models having the same suspensions and added some connection's characteristics between the cars with Vampire program. It is used to analyze the effect on the dynamic performances according to the variation of primary and secondary suspension characteristics in the condition of 6 cars configuration. The results would be useful to manage the potential risks in the next stage of basic and critical design that will be done by the manufacturing company.

In this paper, we introduce the concept of bipolar soft supra topological space and provide a characterization of the related concepts of bipolar soft supra closure and bipolar soft supra interior. We also establish a connection between bipolar soft supra topology and bipolar soft topology. Additionally, we present the concept of bipolar soft supra continuous mapping and examine the concept of bipolar soft supra compact topological space. A related result concerning the image of the bipolar soft supra compact space is proved. Finally, we identify the concepts of disconnected (connected) and strongly disconnected (strongly connected) space and derive several results linking them together. Relationships among these concepts are clarified with the aid of examples.

Green Frame is an environmentally friendly column-beam system composed of composite PC members that can increase buildings' life spans while reducing resource consumption. Typically, connections of PC and RC columns occur at the boundaries of each floor, which is at the upper section of slabs, causing the boundary of each floor to generate the maximum moment. Although it is not optimal in terms of structural safety to connect members at a location where the moment is high, this approach is highly adopted due to its constructability. We propose that a superior approach that employs the concept of connecting columns at the low bending moment zone can be applied to quickly and safely install green columns, the main structural members of Green Frame. Connection of green columns at the low bending moment zone can be classified into three techniques, depending on the method of reinforcing the joints, which have different connection characteristics and construction methods. Research is needed to compare the features of each method of reinforcing the joints so that the most appropriate column connection method can be chosen for the site conditions. This study aims to confirm the structural safety of the connection component at the low bending moment zone and to compare and analyze the construction duration, unit price, quality and safety performance of each column connection method. The study results are anticipated to activate the use of composite precast concrete and to be used as development data in the future.

This research explores diachronic fashion design trends through a structure analysis of a connection network based on fashion show concepts implemented by modern fashion designers from S/S 2009 to F/W 2013. The findings from this research are as follows. First, four categories affect the inspiration and thinking of design: the experience of the designer, social atmosphere and phenomena, natural sensitivity (or formative characteristics of natural objects), and the influence and quality of other fields. Second, in cases where the designers' experiences influenced design inspiration and thinking, designers express personal memories with keywords like high school, grandmother's closet, prom, beauty and the beast, heritage, past, and reminiscence through design elements such as lines, silhouettes, materials, and colors. Third, the representative example of the social atmosphere and phenomena that influenced design inspiration and thinking was the 2008 Global Financial Crisis that reflected the social climate through design concepts of keywords such as Recession, Black, Economy, US, Depression, Gray, Dark Age, White and New York. Fourth, inspired by nature and the formative characteristics in design, the designers employed ornamental elements to collections and design concepts that focused on nature words connected to light, sun, wild, dirt, rock, moss, and trees. Fifth, the designers took their ideas from different fields of personal interest in the arts, science and humanities (sports, architecture, sculpture, painting, and literature) that were decisive in determining materials, design colors and silhouettes. The theme of architecture was analyzed as a central element that had an ongoing impact on the concepts of designers.

본 연구는 제 7차 교육과정의 국민공통기본교육과정에 따른 과학과 생물영역 물질대사와 관련한 개념의 수준과 연계성에 대해 조사하였다. 분석에 사용된 교과서는 초등학교는 1종 검인정 교과서를 사용하였으나, 중학교와 고등학교는 분석의 일관성을 유지하기 위하여 동일 출판사에서 개발한 3종의 교과서를 사용하였다. 물질대사와 관련한 개념은 초등학교에서는 42개, 중학교에서는 3개 출판사 평균 92개, 고등학교에서는 평균 59개가 제시된 것으로 조사되었다. 출판사에 따라 다소 차이는 있었으나 학교급이 올라감에 따라 점차적으로 구체적 개념에 대한 형식적 개녕의 비율이 감소하는 것으로 나타났으나, 학습개념의 수는 급격하게 증가하는 것으로 나타났다. 교육과정 및 교과서 개발 시 학습단원에 따른 학습개념의 제시는 학습자의 인지 수준 및 제시되는 개념의 수를 적정화해야 하며, 단원과 학습 내용의 수직적 연계성을 고려한 구성이 필요하다.

To avoid premature damage to the connection joints of a conventional precast concrete shear wall, a new precast concrete shear wall system (NPSW) based on a plastic damage relocation design concept was proposed. Five specimens, including one monolithic cast-in-place concrete shear wall (MSW) as a reference and four NPSWs with different connection details (TNPSW, INPSW, HNPSW, and TNPSW-N), were designed and tested by lateral low-cyclic loading. To accurately assess the damage relocation effect and quantify the damage and deformation, digital image correlation (DIC) and conventional data acquisition methods were used in the experimental program. The concrete cracking development, crack area ratio, maximum residual crack width, curvature of the wall panel, lateral displacement, and deformed shapes of the specimens were investigated. The results showed that the plastic damage relocation design concept was effective; the initial cracking occurred at the bottom of the precast shear wall panel (middle section) of the proposed NPSWs. The test results indicated that the crack area ratio and the maximum residual crack width of the NPSWs were less than those of the MSW. The NPSWs were deformed continuously; significant distortions did not occur in their connection regions, demonstrating the merits of the proposed NPSWs. The curvatures of the middle sections of the NPSWs were lower than that of the MSW after a drift ratio of 0.5%. Among the NPSWs, HNPSW demonstrated the best performance, as its crack area ratio, concrete damage, and maximum residual crack width were the lowest.

Contemporary architecture has a tendency to concretely approach based on the concept of Deuleuze's 'fold' diversity problems creating continuously potential diversities within Post-structural paradigm. Contemporary architecture relates to human life through its relation with human being. The research investigates through case study the possible relation of the concept of Deulezue's 'fold', one of his concepts of 'unfolding' based on Monadology, with logic of creation that constructs a space in contemporary architectural space. Eight contemporary architectural spaces since 1990 with architectural embodiment of Deulezue's 'fold' concept have been selected as cases. Based on the fact that the potential possibility of a space can be embodied by the thinking of 'fold', the research draws four physical activities such as 'properties connection', 'beyond border', 'diversity of circulation' and 'potential opportunity', through which it studies on the principle of actualization of space creation. Consideration of metaphysical theory as a pre-modern and outdated one may lose a huge potentiality. Leibniz's metaphysics can be rediscovered as a model that provides diverse potentiality. The concept of 'fold' in Monadology needs be reconsidered because it possibly suggests a methodology that embodies through the actualization of space the meanings underlain in contemporary architectural space.

The units about electricity in 5th and 6th science curriculum for elementary school was analyzed and the elementary students' understanding of related concepts was investigated. This study was to make connection between the research about alternative concepts and writing textbooks. It was found that students' response had following characteristics. They had strong belief that the + and - ends of battery should be connected. However this belief was not complete because students did not understand that the other circuit elements had to be connected properly. When the circuit involve more than one bulbs or batteries, they counted the number of batteries or bulbs only and paid little attention to the connection of them. In explaining circuits and the brightness of the bulbs in the circuits. students tried to explains the circuit using scientific terms but failed to used them properly. Although the concept of resistance was not dealt explicitly. student had reasonable qualitative understanding about resistance. According to response of students, several suggestions might be made for the curriculum. The structure and the circuit elements and the proper connection needs to be taught. Also more emphasis is necessary to pay attention to the connection in addition to the numbers of bulbs or batteries. Finally, it needs to be investigated carefully if it is better to introduce some qualitative model to explain the amount of current through bulb depending on the connection and the number of bulbs. It might also be better to introduce some terms, such as current and resistance with the model.
