Manfredo Tafuri's Ideological criticism in architecture has opened a new horizon to interpreting architecture in modern capitalist architecture for it views architecture not just as a style or formal invention, but in terms of socio-economical process. It offered a comprehensive understanding of a chaotic situation of contemporary architecture and historical meaning modern architectural movements in relation with capitalistic development. However, it has been criticized as architectural pessimism which does not allow any possibility for progressive architectural practice. It was also criticized of epistemological problem of how one could be outside ideology without assuming true consciousness against false consciousness of ideology. Tafuri solves this problem by assuming Althusserian activist concept of knowledge and suggest the concept of labor of writing history of critical historians, instead of a design for utopian society, as a possible critical architectural practice. However, I argue that ultimately ideological criticism does not deny architectural practice itself, nor researches on formal characteristics of architecture. The problem lies rather in the architectural Intellectuals' attachment to the traditional concept of architect as a form giver to the society. By rejecting this myth and broadening the concept of architectural practice from design to production, we can find that Ideological problem is not architectural pessimism, but rather it opens up a new way of approaching to the problem of architectural practice in modern capitalist society.

This study consists of two parts, in which the traditional discourses about light and color are analysed hermeneutically, The first part deals with the optical and chromatic discourse that stands in the same context with the aesthetic, and the second with the analysis of color phenomenon that is constituitive of space. From the ancient time the basic parameters of the conceptual thinking such as the virtual, simulacrum, have sticked to the inevitable status, which mediates to represent the original that can never present by oneself. In modern times this specificity of the virtual could have been connected with the problem, how and by which means objects can be perceived and grasped in itself. Among the barometers to the problem ‘color’ or ‘color perception’ has been regarded as the distinct one, in which the relationship between the image and the identifying of this one, the relationship between the perceived image and the perceiving subject and the problem of the spatiality of color and surface can be dwelled on. Through the explication of the chromatic and aesthetic discourse it can be recognized that color, surface and space are interacted with one another. Colors on the surface are not only the dynamic interpoints between the memory and the forgetfulness, but also the virtual interfaces, in which the spatialising actions happen incessantly. At this point it can be illuminated that the space-constituitive dimension of color is correlative with the dimension of chromatic effects of spatialising. Therefore color as well as surface as the spatial happening must be apprehended as the one, which constitutes the spatialising and at the same time varies and shifts itself into another on the purpose of the other spatialising.

Marionette controlling robot has a problem that generates interference in rotation and intersection, therefore, the research on the independent shifter to move freely on the stage is required. Connecting omni-directional mobile robot with marionette controlling robot can solve this problem. Omni-directional mobile robot makes itself rotate and translate in 2D plane freely. Magnetic device is used to connect the moving part with the control part of the robot to minimize the intereference generated by the movement of robot. When robot moves, it can move to all directions with the suitalbe setting of banlance power. The moment of inertia is minimized by dividing the robot to the upper and lower parts in the marionette performance stage. Rotation and interference problem of independent omni-wheel Robot can be solved by using the permanent magnet. The efficiency and safety of the marionette controlling robot is proved by the experiment.

When the structure supporting the rotor as well as the rotor itself is in the resonant range, it cause the vibration problem. Although the static characteristics of structures was considered during the design process, we must consider the resonance problem between the excitation(the main revolution frequency of the rotor) between the dynamic characteristics of its structures. This paper presents we improved the dynamic characteristic of a bearing support system to remove a resonance problem so that stabilized the turbine-generator system.

The development of mathematical problem solving ability and the making(transforming) mathematical problems are consistently emphasized in the mathematics curriculum. However, research on the problem making methods or the analysis of the characteristics of problem making methods itself is not yet active in mathematics education in Korea. In this study, we concretize the method of deductive problem making(DPM) in a different direction from the what-if-not method proposed by Brown & Walter, and present the characteristics and phases of this method. Since in DPM the components of the problem solving process of the initial problem are changed and problems are made by going backwards from the phases of problem solving procedure, so the problem solving process precedes the formulating problem. The DPM is related to the verifying and expanding the results of problem solving in the reflection phase of problem solving. And when a teacher wants to transform or expand an initial problem for practice problems or tests, etc., DPM can be used.

In this paper, we propose a new teaching-learning model with two-step feedback on programming language learning, which is a basic preliminary learning for programming. Programming learning is aimed at improving problem solving skills and thinking by experiencing problem solving through programming. For programming, the learner must know how to work with the computer and what to do with it. To do this, concrete thinking should be established and described in an accurate programming language. In recent, most studies have focused on the effects of programming learning and have not studied the effects of education on language itself. Therefore, in this study, the teaching-learning model for programming language education is presented and applied to the field, and the results are compared with the existing instructional-teaching model.

This paper discusses a new method of recognizing patterns employing consistent labeling. A consistent labeling problem is a generalized expression of constraint satisfaction problems. When a pattern is recognized by pattern matching, the matching between a reference pattern and an acquired pattern resolves itself into finding correspondence between the pixels on the former and those on the latter. This can be expressed as a consistent labeling problem. Pattern association, a variation of pattern recognition, is also described employing consistent labeling. The proposed technique is supported by experimental results, yet further studies need to be done before its practical use.

The purpose of this research was to compare mathematically gifted students with non-gifted students in perception of learning environments, learning ability beliefs, and preference for problem-solving and task. Thirty-seven mathematically gifted students and 75 general students in middle school completed questionnaires about perceptions about mathematics. Data were analyzed by ${\chi}^2$ test and t-test. Compared with general students, mathematically gifted students estimated their talents for mathematics higher, studied mathematics more, expended more time and effort to solving difficult problems, put learning mathematics itself as their primary purpose for studying mathematics and regarded inappropriate environments as the major obstacle to mathematics study. Mathematically gifted students perceived their parents' support higher, solved problem creatively, and had higher preference for challenging tasks.

Games such as sports, RTS, RPG, which teams of players play, require advanced artificial intelligence technology for team management. The existing artificial intelligence enables an intelligent agent to have the autonomy solving problem by itself, but to lack interaction and cooperation between agents. This paper presents "Level Unified Approach Method" with effective role allocation and autonomy in multiagent system. This method allots sub-goals to agents using role information to accomplish a global goal. Each agent makes a decision and takes actions by itself in dynamic environments. Global goal of Team coordinates to allocated role in tactics approach. Each agent leads interactive cooperation by sharing state information with another using Databoard, As each agent has planning capacity, an agent takes appropriate actions for playing allocated roles in dynamic environments. This cooperation and interactive operation between agents causes a collision problem, so it approaches at tactics side for controlling this problem. Our experimental result shows that "Level Unified Approach Method" has better performance than existing rental approach method or de-centralized approach method.

During the past 20 years, a small but potentially powerful initiative has established itself in the mathematics education landscape: Mathematics Across the Curriculum (MAC). This curricular reform movement was designed to address a serious problem: Not only are students unable to demonstrate understanding of mathematical ideas and their applications, but also they harbor misconceptions about the meaning and purpose of mathematics. This paper chronicles the brief history of the MaC movement. The sections of the paper correspond loosely tn the typical steps one might take to solve a mathematics problem. The Problem Takes Shape presents a discussion of the social and economic forces that led to the need for increased articulation between mathematics and other fields in the American educational system. Understanding the Problem presents the potential value of exploiting these connections throughout the curriculum and the obstacles such action might encounter. Devising a Plan provides an overview of the support systems provided to early MAC initiatives by government and professional organizations. Implementing the Plan contains a brief description of early collegiate programs, their approaches and their differences. Extending the Solution details the adoption of MAC principles to the K-12 sector and throughout the world. The paper concludes with Retrospective, a brief discussion of lessons learned and possible next steps.
