The performance-related industry has grown independently without being protected by the nation's great policy and legal boundary in the meantime. Even in the aspect of performance Act, the thoroughly pro-regulation policy on culture & art was taken while proceeding with segmenting the legislation rather than the freedom of performance art or the promotion of performance activity. Totally 17 cases of regulations including the abolition of scenario review system in January 1999 were fully abolished. Even 6 cases of regulations were steeply eased. Also, the importance of culture & art was recognized. Thus, to promote and support it in the governmental dimension, the substantial performance art policy system was adopted for training the performance art staff manpower and the national subsidy on performance hall. In performance art, the necessity of professionals' participation was imprinted such as stage lighting, sound, and stage machine. Accordingly, many regulations on performance art were all abolished except only the minimum issues for maintaining public order in about 50 years since the establishment of the government. 'Movie' was excluded from the definition of 'public performance' in 2002. Thus, the performance report system, which had been left institutionally from the Japanese colonial period, was eternally abolished. Following this, the performance Act was changed into the legislation of the supporting promoting policy, which reflected historical situation of needing to contribute to promoting public welfare, from the regulation-centered Act.

Film-induced tourism in Gyeongbuk and Korea is concentrated on the on-location set, one-off events and film tourism as part of a holiday(visiting film locations or studios as an activity within a larger holiday) among several forms of film-induced tourism. Film-induced tourism in Gyeongbuk has been increased since the opening of the KBS on-location set of Mungyeong. The on-location set has brought the growth of film-induced tourism and thus many local governments have competed with one another for the construction of the on-location set without considering the management of the on-location set. This study is aimed at suggesting ways to minimize these negative problems and to boost film-induced tourism. First of all, we should find ways to sustain each characteristic of the on-location set. Second, we should develop the new tourism destinations by diversifying the forms of film-induced tourism through the opening of the film-related events and the construction of the film-related facilities. Last, film-induced tourism should be enlarged to contents tourism. It needs to enlarge the role of the Gyeongbuk Film Commission. The Gyeongbuk Film Commission should take exclusive responsibility of developing the film-related tourism commodities.

Animation-related films and game industries have been expanding their markets rapidly responding to sharply increasing public demand. The production processes of major studios are getting more and more specialized and detailed. Therefore, they feel burden to manage and maintain as the HR and physical sizes are getting greater. So, independent studios which perform partial processes of the works are increasing over North America and Europe. Specialized studios build previous functions and related business models. They are expanding their areas. Therefore, this study targeted studios specialized in digital concept art in free production step. The characteristics of such studios were analyzed. To this end, first definitions of digital concept art concepts and functional & artistic features of entire production, and their application to business were deliberated through documents and online. Based on the results, the features of 'concept art service', 'self-brand business/ communication', and 'education service' were drawn. Second, based on it, targeting three con cept art studios such as Atomhawk (UK), FengZhu Design (Singapore), and Studio Gage (Korea), case research was done. Comparative analysis for the cases was conducted. It turned out that concept art studio s lead new market demand through active business strategies such as related contents development, marketing, etc. based on specialization. This research is significant to understand global trend of newly establishing specialized studios market and suggest reference data to improve prospective domestic specialized studios competitiveness.

High strength and fracture toughness of Al-Li-Cu alloy(2090 Al alloy) have been achieved by the improvement of melting and casting, extrusion and heat treatment techniques. To establish the sucessful process for semi-industrial scale ingot(20Kg) the following areas have been investigated: (1) Improvement of melting and casting techniques for ingot by introducing atmospheric modifications, vacuum and rotary degassing, and deslagging. (2) The effect of heat treatment on mechanical properties (3) Mechanical characterization by tensile test, fracture toughness test and fatigue crack propagation test. High mechanical properties were found to be intimately related with ingot soundness. Tensile strength of final products varied from 534MPa to 566MPa in peak aged condition while elongation/ductility ranged from 9.0% to 11.9%. From the fracture toughness test with using compact tensile specimen, plane strain fracture toughness($K_{Ic}$) appeared to be 39MPa${\surd}$m in peak aged condition and 23MPa${\surd}$ m in underaged condition. When load ratios of 0.1, 0.3 and 0.5 were given ${\Delta}K_{th}$ was 6.0MPa${\surd}$ m, 5.3MPa${\surd}$ m and 4.3MPa${\surd}$ m respectively.

The prediction of box office performance in performing arts institutions is an important issue in the performing arts industry and institutions. For this, traditional prediction methodology and data mining methodology using standardized data such as cast members, performance venues, and ticket prices have been proposed. However, although it is evident that audiences tend to seek out their intentions by the performance guide poster, few attempts were made to predict box office performance by analyzing poster images. Hence, the purpose of this study is to propose a deep learning application method that can predict box office success through performance-related poster images. Prediction was performed using deep learning algorithms such as Pure CNN, VGG-16, Inception-v3, and ResNet50 using poster images published on the KOPIS as learning data set. In addition, an ensemble with traditional regression analysis methodology was also attempted. As a result, it showed high discrimination performance exceeding 85% of box office prediction accuracy. This study is the first attempt to predict box office success using image data in the performing arts field, and the method proposed in this study can be applied to the areas of poster-based advertisements such as institutional promotions and corporate product advertisements.

In these days, 3D dynamic simulation is closely related to many industries. In the past, physically-based 3D simulation was used mainly in the car crash or construction related fields, but it also plays an important role in movies or games today. Many mathematical computations are needed to represent the 3D object realistically, but it is difficult to process a large amount of calculations for simulation of application based on CPU in real-time. Recently, with the advanced graphic hardware and improved architecture, GPU can be utilized for the general purposes of computation function as well as graphic computation. Many approaches using GPU have been applied for various research fields. In this paper, we analyze the performance variation of two cloth simulation algorithms based on GPU according to the change of execution properties of GPU shaders in oder to optimize the performance of GPU-based cloth simulation. Cloth simulation is implemented by the spring centric algorithm and node centric algorithm with GPU parallel computing using compute shader of GLSL 4.3. We compare the performance of between these algorithms according to the change of the size and dimension of work group. The experiment is repeated to 10 times during 5,000 frames for each test and experimental results are provided by averaging of FPS. The experimental result shows that the node centric algorithm is executed in higher speed than the spring centric algorithm.

The stagnant growth in 3D market due to 3D movie contents shortage is encouraging development of techniques for production cost reduction. Elimination of vertical disparity generated during image acquisition requires heaviest time and effort in the whole stereoscopic film-making process. This matter is directly related to competitiveness in the market and is being dealt with as a very important task. The removal of vertical disparity, i.e. image rectification has been treated for a long time in the photogrammetry field. While computer vision methods are focused on fast processing and automation, photogrammetry methods on accuracy and precision. However, photogrammetric approaches have not been tried for the 3D film-making. In this paper, proposed is a photogrammetry-based rectification algorithm that enable to eliminate the vertical disparity precisely by reconstruction of geometric relationship at the time of shooting. Evaluation of proposed algorithm was carried out by comparing the performance with two existing computer vision algorithms. The epipolar constraint satisfaction, epipolar line accuracy and vertical disparity of result images were tested. As a result, the proposed algorithm showed excellent performance than the other algorithms in term of accuracy and precision, and also revealed robustness about position error of tie-points.

Propaganda is often accepted as the political promotion that had used mostly by the socialist states during the First and the Second World Wars and the Cold War and by Hitler who governed Germany. Therefore, cases of the study on the image and picture propaganda were mostly posters or films of the socialism period when the propaganda was active. However, today it is not easy any more to find propaganda of the clear promotion characteristic as the past. In these modern times, it has changed into metaphorical propaganda based on 'persuasion', rather than publicity like past. Therefore, it has been changing from the direct promotion of the past into the indirect persuasion; and from the raw, direct and powerful publicity and claim into the soft and metaphorical persuasion and appeal. Thus, investigating again the contemporary propaganda will be an important element in analyzing contemporary images. The animation, selected as a target of the analysis of propaganda, exists in various ways in various images of the modern times, which is not too much to say that today's society is the television society. Besides, the animation is the image that can cover all ages as men and women of all ages can watch, so it is proper for analysis of the contemporary propaganda of metaphorical, indirect and various forms.
