This article is about seeking for modern festival possibility of Mudang gut with noticing a festival essence of it. Several components and process of performing Maeul gut can be a festival. But the recent condition of gut pan obstructs becoming a festival. Above of all, distorted eyes on Mudang gut deny a festivity. Transition into seeking for private fortune and the duplicity of concealing a Mudang gut have weakened a festivity of Mudang gut. Maeul gut becomes a ceremony with unequal distribution of support fund and the support fund on intangible cultural assets. Therefore, we should consider Mudang gut as a game. People need to change their preception as a performance that people can actively take part in. Mudang gut need a active participants not bystanders. When people consider them selves as actors, Mudang gut will be a festival.

Floating holograms are technologies that provide rich 3D stereoscopic images in a wide space such as advertisement, concert. In addition, It is possible to reduce the 3D glasses inconvenience, eye strain, and space distortion, and to enjoy 3D images with excellent realism and existence. Therefore, this paper implements a user gesture recognition system for manipulating a floating hologram characters that can be used in a small space devices. The proposed method detects face region using haar feature-based cascade classifier, and recognizes the user gestures using a user gesture-occurred position information that is acquired from the gesture difference image in real time. And Each classified gesture information is mapped to the character motion in floating hologram for manipulating a character action. In order to evaluate the performance of the proposed user gesture recognition system for manipulating a floating hologram character, we make the floating hologram display devise, and measures the recognition rate of each gesture repeatedly that includes body shaking, walking, hand shaking, and jumping. As a results, the average recognition rate was 88%.

Korea paid attention to the work injury insurance in the early economic development stage as other developed countries did. Thus "The industrial Accident Compensation Insurance Law" was legislated in 1963 and it is now expanded to apply to the workplace with five or more employees. Beside the low coverage of the number of employees, the scope of benefits are the problem of work injury insurance. The work injury insurance's main benefits are for the loss of income and the medical cost caused by occupational accidents. On the other hand, the investment on the prevention accident and the medical, social and employment rehabilitation is very low, even though the occupational accident pension is higher than that in other OECD countries. Practically lay-off benefits and survivor' benefit for some special workers are paid more than they need, therefore they want to remain under the benefit condition and the medical care days are longer. This paper indicates the problems of work injury insurance and suggest how to improve the functions of it.

The 3D stereoscopic image contents have been emerging as the blue chip of the contents market of the next generation since the . However, all the 3D contents created commercially in the country have failed to enter box office. It is because the quality of Korean 3D contents is much lower than that of overseas contents and also current 3D post production process is based on 2D. Considering all these facts, the 3D editing process has connection with the quality of contents. The current 3D editing processes of the production case of are using the way that edits with the system on basis of 2D, followed by checking with 3D display system and modifying, if there are any problems. In order to improve those conditions, I suggest that the 3D editing process contain more objectivity by visualizing the depth data applied in some composition work such as Disparity map, Depth map, and the current 3D editing process. The proposed process has been used in the music drama , comparing with those of the film . The 3D values could be checked among cuts which have been changed a lot since those of , while the 3D value of drew an equal result in general. Since the current process is based on an artist's subjective sense of 3D, it could be changed according to the condition and state of the artist. Furthermore, it is impossible for us to predict the positive range, so it is apprehended that the cubic effect of space might be perverted by showing each different 3D value according to cuts in the same space or a limited space. On the other hand, the objective 3D editing by applying the visualization of depth data can adjust itself to the cubic effect of the same space and the whole content equally, which will enrich the 3D contents. It will even be able to solve some problems such as distortion of cubic effect and visual fatigue, etc.

The current display systems including TVs are going digital and large-sized, and high visual quality of those systems becomes a very important selling point in the current display system market. Thus, various researches have been carried out for enhancing the visual quality of digital display systems. One of the important digital image(or video) enhancement techniques is sharpness enhancement, and it is generally based on a transient improvement technique that reduces the edge transition time. However, this technique often generates overshoot and undershoot, which cause undesirable pixel-level changes around the transient improved edge. In this paper, we propose a new nonlinear filter-based adaptive shoot elimination method for effectively suppressing the overshoot and undershoot that occur in the transient improvement, so that we can obtain visually sharper and clearer digital images(or videos). The proposed method uses two orthogonal directional min/max nonlinear filters with an adaptive shoot elimination scheme in order to effectively suppress the visually sensitive overshoot and undershoot. Experimental results show that the proposed method suppresses the overshoot and undershoot almost perfectly while maintaining the effect of the transient improvement. The applications of the proposed method include digital TVs, digital monitors, digital cameras/camcoders, portable media players(PMP), etc.

This paper proposed the content-based retrieval system as a method for performing image retrieval through the effective feature extraction of the object of significant meaning based on the characteristics of man's visual system. To allow the object region of interest to be primarily detected, the region, being comparatively large size, greatly different from the background color and located in the middle of the image, was judged as the major object with a meaning. To get the original features of the image, the cumulative sum of tile declination difference vector the segment of the object contour had and the signature of the bipartite object were extracted and used in the form of being applied to the rotation of the object and the change of the size after partition of the total length of the object contour of the image into the normalized segment. Starting with this form feature, it was possible to make a retrieval robust to any change in translation, rotation and scaling by combining information on the texture sample, color and eccentricity and measuring the degree of similarity. It responded less sensitively to the phenomenon of distortion of the object feature due to the partial change or damage of the region. Also, the method of imposing a different weight of similarity on the image feature based on the relationship of complexity between measured objects using the fractal dimension by the Boxing-Counting Dimension minimized the wrong retrieval and showed more efficient retrieval rate.

A tendency to ignore the existence of public space in Korea under the Japanese colonial period seems to be driven from nationalist historiography in which all historical events under the colonial power have to be interpreted in terms of militant controls and resistances against them. Historical approach to mass media of that period has lasted to be saturated with the tendency and forced history students to stick to the nationalist guidelines. Struggles against Japanese imperial power by national-capital-operated newspaper have been a main menu of studies on the period's communication. The media were often hailed as fighting the colonial power for nation's independence. The present thesis aims to criticize the nationalist point of view and to reveal that nationalist interpretations may miss a variety of historical information. Even under the severe surveillance of colonial police some journalists tried either to inform officially or to smuggle into informed groups. The colonized society could experienced fields of public-ness throughout the practices of such as media fields, cultural fields, political fields. Those fields, of course, didn't come from the graceful favor of the colonial power but from the construction of the colonized. The public-ness seemed to be born for the easiness of control, but became later a constructed field of public-ness with which the colonized semiotically wrestled the power and grew a modern type of political (un)consciousness. Depicting what happened just before 815 liberation day in Korea the present paper showed that the less nationalist historiography can render help to those seeking political practices of the colonized in a micro-level.

Recently, as the prevalence of high-performance mobile devices and the application of the multimedia content are expanded, Super Resolution (SR) technique which reconstructs low resolution images to high resolution images is becoming important. And in the mobile devices, the development of the SR algorithm considering the operation quantity or memory is required because of using the restricted resources. In this paper, we propose a new single frame fast SR technique suitable for mobile devices. In order to prevent color distortion, we change RGB color domain to HSV color domain and process the brightness information V (Value) considering the characteristics of human visual perception. First, the low resolution image is enlarged by the improved fast back projection considering the noise elimination. And at the same time, the reliable edge map is extracted by using the LoG (Laplacian of Gaussian) filtering. Finally, the high definition picture is reconstructed by using the edge information and the improved back projection result. The proposed technique removes effectually the unnatural artefact which is generated during the super resolution restoration, and the edge information which can be lost is amended and emphasized. The experimental results indicate that the proposed algorithm provides better performance than conventional back projection and interpolation methods.
