In this paper, we designed a multi humanoid robot control method for performing an exhibition that will maximize the efficiency and user convenience and implementation. In recent years, an increasing number of case and to take advantage of the robots in the field performances and exhibitions, plays, musicals, orchestra performances are also various genres. In concert with the existing small humanoid exhibition to source from outside by using a computer and MP3 player and play, while pressing the start button of communication equipment for the show to start the robot began performing with the zoom. Thus, due to the dual source and robot operation and synchronization does not work well is the synchronization of the start of the concert sound starting point of the robot and robot motion and sound are reproduced separately were frequently occurs when you need to restart the show. In addition, when the center of gravity or lose the robots who were present during the performance problems such as performance or intervene to restart the show. In order to overcome this, in this paper, Multi-small humanoid robot was designed to control the efficiency and the user of the GUI-based human interface S/W to maximize convenience, Zigbee communication to transmit a plurality of data in al small humanoid It was used. In addition, targeting a number of the small humanoid robot demonstrated the effectiveness and validity of the user's convenience by gender actual implementation.

As virtual realty has become an issue of providing immersive services, in the area of virtual realty, it has been actively investigated to develop user interfaces for immersive interaction. In this paper, we propose a gesture recognition based immersive user interface by using an IR LED embedded helmet and data gloves in order to reflect the user's movements to the virtual reality environments effectively. The system recognizes the user's head movements by using the IR LED embedded helmet and IR signal transmitter, and the hand gestures with the data gathered from data gloves. In case of hand gestures recognition, it is difficult to recognize accurately with the general recognition model because there are various hand gestures since human hands consist of many articulations and users have different hand sizes and hand movements. In this paper, we applied the Mixture-of-Experts based gesture recognition for various hand gestures of multiple users accurately. The movement of the user's head is used to change the perspection in the virtual environment matching to the movement in the real world, and the gesture of the user's hand can be used as inputs in the virtual environment. A head mounted display (HMD) can be used with the proposed system to make the user absorbed in the virtual environment. In order to evaluate the usefulness of the proposed interface, we developed an interface for the virtual orchestra environment. The experiment verified that the user can use the system easily and intuituvely with being entertained.

There are various types of real world signals. For example, an electrocardiogram(ECG) represents myocardium activities (contraction and relaxation) according to the beating of the heart. ECG can be expressed as the fluctuation of ampere ratings over time. A signal is a composite of various types of signals. An orchestra (which boasts a beautiful melody) consists of a variety of instruments with a unique frequency; subsequently, each sound is combined to form a perfect harmony. Various research on how to to decompose mixed stationary signals have been conducted. In the case of non-stationary signals, there is a limitation to use methodologies for stationary signals. Huang et al. (1998) proposed empirical mode decomposition(EMD) to deal with non-stationarity. EMD provides a data-driven approach to decompose a signal into intrinsic mode functions according to local oscillation through the identification of local extrema. However, due to the repeating process in the construction of envelopes, EMD algorithm is not efficient and not robust to a noise, and its computational complexity tends to increase as the size of a signal grows. In this research, we propose a new method to extract a local oscillation embedded in a signal by utilizing the second derivative.

In the period of Japanese occupation comic narratives were popular to such an extent as to be published not only newspapers and magazines but also books as 『Yojigyeong』(1910), 『Jeodobaekhwa』(1912), 『Gaegeonhuihui』(1912), 『Angcheondaeso』(1913), 『Kkalkkaluseum』(1916), 『Socheonsoji』(1918), 『Gogeumgidamjip』(1923), 『Mangogidam』(1924), 『Joseonpaldo iksal & jaedam』(1927), 『Segyesohwajip』(1934). This study is to discuss about how those narratives gain modernity with the titles scattered in 『Byeolgeongon』 as the central figure, and to reveal the nature of the comic narratives in 『Byeolgeongon』 by looking into contents. The comic narratives in the magazine are 149, especially from the titles show the editors' agony at that time. The narratives gain modernity by combining the new trend cultural terms which can't be found in our traditional culture as 'sinbu huboja jeonramhwoe.', 'sinrang huboja jeonramhoe.', 'nonsense teuksseolgwan', 'how modern shipbuilding 10 inventions sinjejo', 'sohwabangsongsil', 'sohwabangsongguk', 'freedom march', 'sinchunpoksodaehwoe' and 'humor orchestra'. The narratives give laughter to the readers by carrying the characters such as wit, enlightenment, critics of social conditions, grotesque. The narratives in the magazine 『Byeolgeongon』 represent much to survive with comic story in a time of gloom in the period of Japanese occupation.
