This study was to provide for Tippelt technique which was a basic technique used in parallel bars. The program was applied to players for 8 weeks. Then it was analyzed by using 3Dmotion Analysis system to seek the difference between before and after using the program. Moreover establish the improvement and trait for newly made program. The program was made up of down-swing, up-swing and composite connection-phase training. Through down-swing training, shoulder angle made extension and chest closed quickly. As a result, players' performance have improved. Through up-swing training, legs kicking to vertical direction and trunk stood up fastly. As a result, players' performance have improved. When going upward, the center of mass must be in control not to have a lot of movement and hip angle extension using the bar is very positive coaching. When coaching composite connection in training from down-swing to up-swing, must have enough air phase time using center of mass vertically to have extension of leg. As a result, players' performance have improved by having increase of air phase time.

In this paper, 3D objects is created from the real scene that is used by an active sensor, which gets depth and RGB information. To get the depth information, this paper uses the $Zcam^{TM}$ camera which has built-in an active sensor module. <중략> Thirdly, calibrate the detailed parameters and create 3D mesh model from the depth information, then connect the neighborhood points for the perfect 3D mesh model. Finally, the value of color image data is applied to the mesh model, then carries out mapping processing to create 3D object. Experimentally, it has shown that creating 3D objects using the data from the camera with active sensors is possible. Also, this method is easier and more useful than the using 3D range scanner.

The purpose of image fusion is to combine the relevant information from a set of images into a single image, where the resultant fused image will be more informative and complete than any of the input images. Image fusion techniques can improve the quality and increase the application of these data important applications of the fusion of images include medical imaging, remote sensing, and robotics. In this paper, we suggest a new method to generate a fusion image using the close relation of image features obtained through maximum entropy threshold and mutual information. This method represents a good image registration in case of using a blurring image than other image fusion methods.

Recent growth of the geospatial information on the web made it possible to applicate spatial data. Also, the demand for rich and latest information shows a steady growth. The need for the new service using conflation of the existing spatial databases is on the increase. The information delivery of the services using the road vector and aerial image is reached intuitionally and accurately. However, the spatial inconsistencies in map services such as Daum map, Naver map and Google map is the problem. Our approach is processed to extract the road candidate image, match the template and filter the control points pair using vector median. Finally, CNS node and link are aligned to the real road with the aerial image. The experimental results show that our approach can align a set of CNS node and link with aerial imagery for daejon, such that the completeness and correctness of the aligned road have improved about 35% compare with the original roads.

Sound scattering by cylindrical tubes submerged in water is numerically analyzed with material attenuation considered. Complex wave numbers is introduced to see the effects of material attenuation on resonance scattering Backscattering pressures from the shells immersed in water are calculated for air-filled aluminium and acryl tubes. In order to investigate the resonance characteristics in detail, numerical analysis program has been completed which enables us to evaluate the effects of material attenuation. The testing of the program by comparison with previous results is reported and calculation results are compared and discussed for both aluminium and acryl tubes with material attenuation considered. The resonance peak and width is strongly affected by attenuation and this becomes severe as the peak is sharp and narrow and $k_{1{\alpha}}$ is high.

To get an implication for desirable direction for Collaboration between Reporter & Producer, I found that had 4 modes of collaboration such as, Producer System, Reporter System, Double Reporting System, Co-Work System, and each was distinguished by field cover, on-mic, editing, writing. Producer system and Reporter system got no chemical synergy because of simple array of single reports due to physical assemble. The achievements of collaboration was birth of new news which had different duration, visual, sound & perspective. It also offered fertile soil for new program and genre literacy of 8 o'clock news. The success factor of collaboration was surprisingly turned out to be personnel rather than system. The balance of reporter & producer was also good factor. But the wall between 2 groups was so high that, after disappearance of extraordinary leader, system began to crumble and at last program was repealed.

Through this thesis, I intended to analyze Hollywood animation through that achieved in box office by directing viewpoint. of Chris Sanders and Dean Deblois not only shows standard narrative structure of adventure, comedy, fantasy, but also express message of story and thorough visual. Analysis of directing classify contents and form. In contents, constitution of narrative and set up of character, irony of plot, characterization and popularity are embossed. In form, lighting and special effect, design and layout, 3D technology and stereoscopic camera technique based on the capital strength are outstanding. The high evaluation for film is possessed of box offic, remained within value and popularity, and delivered metaphysical theme without repulsion. The director's direction make success even if the pre-production manage by huge system approach.

For a reconstruct draft of the Gyupyo (Gnomon) in King Sejong Era, we collected a lot of documents of the Chosen Dynasty. With the result we made a reduced model by 1/10 and drawing set for the Gnomon in Sejong Era. It is composed of the Gyu, Yongpyo, Hoengryang (a beam), Yeongbu and granitic prop. You can read the scale where the shadow of vertically-standing stick touches the horizontal Gyu. A Shadow-Define. (Yeongbu) was used to focus the shadow cast by the sun's center, measuring the (gnomon) shadow length precisely. A Yeongbu is made of a leaf of copper in the middle of which is pierced a pin-hole for the tiny optical image of the sun which tilted to face the incident sunlight, used the principle of the a pin-hole camera and Scheimplug principle.

The one-person producing system is that planning program, arrangements, composition, taking pictures and edition are all done by only one person. In the reality of the producing systems of the broadcasting programs, as the number of the broadcasting stations, which apply one-person producing systems, is gradually increasing, the study on the change is going on. In this study I grasped the merits and demerits of both systems ; multi men producing system and one-person producing system. And then I analyzed the sudden change of the method of the producing programs into one using the 6m digital camera. The merits of producing programs by means of the 6m digital cameras are following ; the mobility of producing programs, a close contact with the source, the enlargement of the diversity of the contents and cutting down expenses. The demerits of it are following ; a lowering of the degree of completion and the unstableness of an image. Nowadays because of the enlargement of the rate of the outsourcing production, the number of the independent production studios rapidly increased. From the viewpoint of cutting down expenses and the diversity of contents, the number of broadcasting programs produced by means of one-person producing broadcasting program system is increasing.

The now video coding standard H.264 employs variable block size motion compensation, multiple references, and quarter-pel motion vector accuracy. These techniques are key features to accomplish higher coding gain, however, at the same time main factors that increase overall computational complexity. Therefore, in order to apply H.264 to many applications, key techniques are requested to improve their speed. For this reason, we propose a fast motion estimation which is suited for variable block size motion communication. In addition, we propose a fast mode decision method to choose the best mode at early stage. Experimental results show the reduction of the number of SAT SATD calculations by a factor of 4.5 and 2.6 times respectively, when we compare the proposed fast motion estimation and the conventional MVFAS $T^{［8-10］}$. Besides, the number of RDcost computations is reduced by about 45%. Therefore, the proposed methods reduces significantly its computational complexity without noticeable coding loss.
