Recently, a service robot industry outstands as an up and coming industry of the next generation. Specially, there are so many research in self-steering movement(SSM). In order to implement SSM, robot must effectively recognize all around, detect objects and make a surrounding map with sensors. So, many robots have a sonar and a infrared sensor, etc. But, in these sensors, We only know informations about between the robot and the object as well as resolution faculty is of inferior quality. In this paper, we will introduce new algorithm that recognizes objects around robot and makes a two dimension surrounding map with a omni-direction vision camera and two stereo vision cameras.

In this paper, we proposed a brain-computer interface system using EEG signals. It can generate 4 direction command signal from EEG signals captured during imagination of subjects. Bandpass filter used for preprocessing to detect the brain signal, and the power spectrum at a specific frequency domain of the EEG signals for concentration status and non-concentration one is used for feature. In order to generate an adequate signal for controlling the 4 direction movement, we propose a new interface system implemented by using a support vector machine and a time-multiplexing method. Moreover, bio-feed back process and on-line adaptive pattern recognition mechanism are also considered in the proposed system. Computer experimental results show that the proposed method is effective to recognize the non-stational brain wave signal.

Visual surveillance is an active topic recently in Computer Vision. Event detection and recognition is one important and useful application of visual surveillance system. In this paper, we propose a new method to recognize the entering and exiting events based on the human's movement feature and the door's state. Without sensors, the proposed approach is based on novel and simple vision method as a combination of edge detection, motion history image and geometrical characteristic of the human shape. The proposed method includes several applications such as access control in visual surveillance and computer vision fields.

Tardive dyskinesia (TD) is continuous, repetitive movement disorder of tongue, lip or jaw, induced by medication. It causes pain and dysfunction of oral structures but also interferes with dental treatment and overall social life of patients. As a dentist, it is imperative to recognize and manage TD, although currently, there is no definitive treatment for TD. This article reports a patient with TD of tongue, successfully managed with an oral appliance mimicking sensory tricks. Considering the limited treatment options for TD, an oral appliance, a simple and conservative approach, can be a meaningful treatment for some patients with orofacial dyskinesia.

Many companies in Korea have introduced and put Six Sigma to the practical use recently, others are under consideration to introduce it. As we consider how to recognize and to apply it, we are able to know there is a difference among companies and it differently influence on those companies. In this paper, we analyze the structural differences between Quality Management and Six Sigma movements through the questiionnaire designed effectively to investigate them. We also examine the controversial points, suitability as the management model, the level of Quality Management and Six Sigma movements, and analyze how much the movements effect on the management activities. Finally, we show how to improve the Quality Management and Six Sigma movements in Korean companies.

The study is Intended to clarify the ideologies and principles applied to the formative expression of church architecture which is contained both the God and human. After modern times, from the result of study of modern architectural movement, all of architectural ideology have not been developed with the church architecture. Some of architectural concept have been the foundation of modern church architecture. Among them, focusing the area which is developed the form of the church architecture wish the regional architectural expression -America, Northern Europe and Latin America - the expressional characteristics have derived that the church architecture have specific characteristics by the analysis of the characteristics from the influence of the regionalism. After all, regionalism-church architecture which describes recognized and behavioral organism and recognize the kind of the regional tradition and show regionalized formation shows the expressional characteristics of modern church architecture.

The purpose of this study is to improve the performance of robot by providing visual function with robot and developing high-functioned controller and control program. The developed high-functioned controller and software have the better accuracy and flexibility in the movement of robot by complementing the existing robot controller and software problems. To provide visual function to robot, camera calibration, thresholding and contouring tools are also developed and applied in this study. These tools help robot recognize the central points and orientations of objects on work-bench.

It is important to detect objects movement for obstacle recognition and path searching of UCT(unmanned container transporters) with vision sensor. This paper shows the method to draw out objects and to trace the trajectory of the moving object using a CCD camera and it describes the method to recognize the shape of objects by neural network. We can transform pixel points to objects position of the real space using the proposed viewport. This proposed technique is used by the single vision system based on floor map.

In this paper, we propose and implement VVVV base interactive advertisement. It has now expanded from the traditional marketing methods of television, radio, newspapers and magazines to become a digital marketing era. However, it is still in the form of infusion-type advertising, similar to traditional marketing techniques. For more innovative we put story and design elements into digital technology. Consumers will feel fresh excitement as they experience advertising. Emotional stories and image will also provide an element for customers to talk to each other. The propose advertisement is design to recognize the movement of people in the corridor by using Arduino and ultrasonic sensor installed in the passageway where many people pass. Arduino and VVVV takes people's movements for a values. This values change the advertising image. In this case, we applied the mask in VVVV so that the image to be reproduced and the image of the background role are displayed when the person passes the sensor. By realizing this interactive advertisement, the objective is to increase the buyer's purchasing power by approaching the buyer more effectively than the existing advertisement.

Techniques to recognize depth values using Kinect infrared projectors continue to evolve. Techniques to track human movements are being developed from the Marcris method to the Bimarris method. Capture of facial movement using Kinect has disadvantages that are not sophisticated. In addition, a method to control the gestures and movements on the face in real time requires much research. Therefore, this paper proposes a technique to create natural 3D image contents by studying technology to apply and control branding technology to extracted face recognition data using Kinect infrared method.
