초기의 애니메이션은 단순히 삽화에 움직임을 줌으로서 살아있는 듯한 표현의 리얼감을 목표로 하였다. 이후 애니메이션은 미디어 기술의 발달과 인간의 의식변화, 그리고 사회현상들의 다양한 변화에 의해 영향을 받고, 영향을 끼쳐왔다. 그 중에서도 1946년에 처음 등장한 컴퓨터는 애니메이션의 리얼리티 표현의 도구를 더욱 다양화시켰고, 나아가 표현 매체의 지적능력 향상을 초래하여 새로운 시각영역의 확대와 의식을 확장하는 다원적인 영상정보 환경으로 바뀌었다. 또한 이 기술은 모든 영역에 있어서 보편적 질서의 해체와 다의적이고 다양함과 모호함, 그리고 때로는 서로 모순적인 요소들이 함께 내포하고 있는 포스트모더니즘 속에서 애니메이션은 기존의 리얼리티(지각적 리얼리티와 반영적 리얼리티)에서 새로운 돌파구를 찾아야만 하였다. 따라서 애니메이션은 단순한 화상처리라는 기술의 벽을 넘어서서 논리적인 지각과정의 경로보다 빠르고 즉흥적이고 감성적으로 지각할 수 있는 리얼리티로의 전환을 이루게 된 것이다. 이를 본 연구에서는 '감각적(感覺的) 리얼리티'라고 명명하며, 이에 관한 연구의 일환으로서 질 들뢰즈(Gilles Deleuze,)의 공간에 관한 리얼리티를 실제 애니메이션영화에 적용하여 해석하고 있다.

A virtual reality system is implemented for the operator supervising a robot's operation at a remote site. For this implementation, a two D.O.F force-reflective joystick is designed to reflect the force/torque measured at the end of robotic manipulator and to generate the motion command for the robot by the operator using this joystick. In addition, the visual information that is captured by a CCD camera, is transmitted to the remote operator and is displayed on a CRT monitor. The operator who is holding the force reflective joystick and watching the CRT monitor can resolve unexpected problems that the robot confronts with. That is, the robot performs the tasks autonomously unless it confronts with unexpected events that can be resolved by only the operator. To demonstrate the feasibility of this system, a remote peg-in-hole operation is implemented and the experimental data are shown.

This paper focuses on the specificities and semantic meaning of Mikhail Bulgakov's metadrama White Guard and The Flight. The standard conception of metadrama is to purposefully break the dramatic illusion and make bare a playwright's self-consciousness of the theatrical art itself. With the use of the metadrama Bulgakov expressed the essentials of ugly reality, which he couldn't accept as a valuable truth. In this respect, Bulgakov's metadrama becomes at once a window, from which he views the external world in the theatrical vision, and a mirror, in which his political and existential stance as a playwright is reflected. In White Guard Bulgakov described the already theatricalized reality through several instances of 'play-within-play'. In The Flight, composed of eight pieces of dream, a life turned out to be a less solid and less firm reality than dream. Continuously demolishing the cognitive wall between reality and illusion, Bulgakov leads spectators to have a reflective view on the reality. Allowing more powerful demonstrativeness for a play-within-play than for a play-within-play, Bulgakov elevates a metadramatic technique to the level of thematic structure.

The purpose of this research is to apprehend what the power of professional learning community (PLC) to make home economics teachers participate is and how PLC activity contributes to reflective practice and change of participating home economics teachers by experiencing reflective practices. For this, self-reflective action research of Kemmis and McTaggart was conducted. Six home economics teachers participated voluntarily and totally 18 PLC sessions from May 31, 2013 to May 19, 2014 were held. Two themes of 'looking in classes' as a main practice theme and 'designing classes together' as a supporting theme were carried. Findings and conclusions of this study are as following. First, participants of PLC to get data and information on teaching and to solve problems with fellow teachers for better classes at first. However, they have become to comfort and sympathize each other about difficulties in school as home economics teachers. Second, through the PLC activity, they found they had uncomfortable belief about teaching and tried to practice solutions by critical and reflective thinking. Third, they put efforts in finding alternative framework of looking inside their classes for the fundamental improvement in teaching. For this, they formulated questionnaire to describe their own reflective practice through the alternative framework from a critical perspective in teaching, a view of student's learning, and a teacher's inner view for improvement of practice. Fourth, PLC activity for a year allowed them to combine theory and reality though reflective process by designing classes together and reflectively practicing them in classes.

Traditionally in IS studies, the relationship between construct and its measurement items tends to be assumed to be reflective, meaning that the measurements are a reflection of the construct. In reality, however, the nature of the construct can be often formative, which means that its measurement items describe and define the construct rather than vice versa. The purpose of this study was to investigate theoretical and empirically-analysed differences between formative construct and reflective construct through comprehensive interdisciplinary literature review. And then on the basis of these differences, we intended to derive the rule of specifying whether the construct is formative or reflective and propose the methodology of testing the validity(content validity, construct validity, internal consistency and external construct) of formative construct and its measurements, differentiated from that in the case of reflective construct. Also, we suggested the concrete statistical testing methods such as VTT(Vanishing Tetrad Test), MIMIC(Multiple Indicators and Multiple Causes) test and multi-collinearity test. In order to examine the applicability of this methodology to developing the constructs for performance evaluation of IS(Information Systems), we tried to identify its attribute(formative or reflective) and test the validity for the construct arbitrarily chosen among them which had been derived in our previous IS performance evaluation study by using this methodology. The result of the examination was that the methodology proposed in this study was significantly valid and effective in the area of IS performance evaluation.

This study focuses on the Mise-en-abyme theories of Lucien $D{\ddot{a}}llenbach$, and presents research methodology to analyze the modern cinema costume in a new view. Inherent aesthetic values of the costume code shown in the film are as follows. First, esthetics value shown is the analogic code through the maximization of factual realism by directing target. Mise-en-abyme placed in this film plays the role of costume codes, and highlights the subject by presenting specifically targeted realistic icons to maximize the realism of the movie. Second, Mise-en-abyme is deployed to the explicit text through costumes code is placed as Displaced code arrangements. In other words, each of the characters is a signifier. Symbolizing a historical era is the device that represents a self-reflective signifier. Third, paradoxically reflected by the overlapped expansion of virtual reality and the self-referential characteristics and are subject to reflect the thinking of the author. Costumes code placed in Mise-en-abyme is expressed in costumes positioned to maximize the realism in the film as described above, and implies narratives and self-reflective mediating tools that symbolism can be seen that the paradoxical metaphor for the reality and the future. In addition, through the metaphor of visual narrative is allegorical representation Mise-en-abyme with ambiguity, and it is a concrete text that can be realized in a variety of creative storytelling methods and image delivery methods of modern fashion. This study confirmed that this costumes to take the point of view of emotional $Mise-en-sc{\grave{e}}ne$ in the process of completing the film's themes and cinematic devices by identifying the roles and aesthetic value of code costumes as the core subjects that make up the narrative of the film.

To achieve autonomous mobile robot navigation, accurate localization technique is the fundamental issue that should be addressed. In augmented reality, the position of a user is required for location-based services. This paper presents indoor localization using infrared reflective artificial landmarks. In order to minimize the disturbance to the user and to provide the ease of installation, the passive landmarks are used. The landmarks are made of coated film which reflects the infrared light efficiently. Infrared light is not visible, but the camera can capture the reflected infrared light. Once the artificial landmark is identified, the camera's relative position/orientation is estimated with respect to the landmark. In order to reduce the number of the required artificial landmarks for a given environment, the pan/tilt mechanism is developed together with the distortion correction algorithm.
