After the efficiency of H.264 video compression has been announced, it replaced MPEG-2 standard in several applications. So transcoding methods of MPEG-2 to H.264 have been studying because there are variety devices and contents followed by MPEG-2. Although H.264 supported various service such as IPTV, DMB, digital broadcasting etc, but users using MPEG-2 devices cannot accessible to them. This paper propose H.264 to MPEG-2 transcoding for users of MPEG-2 devices without displacement H.264. The proposed method predicted a motion vector for MPEG-2 encoder after it extracted from motion vectors of variable blocks in H.264 to improve processing time. Also it predicted a optimal motion vector using modified boundary matching algorithm after grasped a special character for boundary and background of object. The experimental results from proposed method show a considerable reduction in processing time, as much as 65% averagely, with a small objective quality reduction in PSNR.

It is a daunting task to theorize the process effectiveness of IT convergence based service model. Despite the criticalness of investigating process enhancement impact of IT-convergence based service model, the theoretical research in this field is relatively scarce, possibly due to the too wide and comprehensiveness of research scope. In this vein, we conducted exploratory study to understand the contributional impact of IT convergence based service model on resolving service process limitations. We first identified five IT convergence based service models in the area of typical service industry, which include entertainment, learning, location based services, tourism, and healthcare. Our research model classified value creation factors of the IT convergence model in twofold. The one is defined as basic value creation factor of the IT convergence, which is treated as the second-order factor that consists of two first-order factors of mobile functionality and Internet with digital contents merging functionality. The other is defined as service process limitations resolving factor which are comprised with the two first-order factors of simultaneousity and perishability. Both the second-order factors are modeled, each respectively, with the two first-order factors in formative manner. Using PLS, empirical validation is executed to analyze each value creating factor's contribution impact on the relative advantage, as well as the mediating effect of basic value creation factor on resolving service process limitations. On the basis of the insights revealed from this paper, further theory building research could be elaborated in the area of IT convergence applications for service industry.

The purpose of this study is to apply a concept of open structure to clothing design and to verify the characteristics found in the various types of clothing which has open structure. The literatures from various academic fields including philosophy, literature, social science, architecture, and fine arts are investigated to define the concept of openness and to analyze it from the perspectives both of the visual and of the moaning of openness. This paper is to identify the types and the characteristics of clothing by future intention, complexity, discontinuity of open structure. By closely examining fashion design after 1980s found in fashion collection publications and designer's websites, the results of this study are as follows: first, the concept of openness can be classified into two different levels, that is, visual and meaning, secondly, in clothing the concept of open structure is applied to the meaning side by future intention, by complexity and by discontinuity. Open structure through future Intention has new content and interpretation and must have the possibility of intelligence awakening, future guidance and basic contents. Open structure through complexity has secondary function exists concurrent with the shape key example is the smart clothes with the digital functions. It has functions of amusement, supplement and protective, and is future clothes which satisfies with health, welfare, desire of beauty. Open structure with discontinuity is clothes with dramatic changes in system, structures and states. Structure can be changed by silhouette, detail, or fabric, material, or dramatic and practical function as tools in terms of productions and environment. This study can help to formulate and to integrate the concept of open structure in clothing with various phases and enhance the value of clothes by showing an application of the concept of openness to the clothing in meaning level.

Recently, animation contents has become extensively available along with the development of cultural industry. In this paper, we propose a method to analyze a face of animation character and extract 3D rotational information of the face. The suggested method first generates a dominant color model of a face by learning the face image of animation character. Our system then detects the face and its components with the model, and establishes two coordinate systems: base coordinate system and target coordinate system. Our system estimates three dimensional rotational information of the animation character face using the geometric relationship of the two coordinate systems. Finally, in order to visually represent the extracted 3D information, a 3D face model in which the rotation information is reflected is displayed. In experiments, we show that our method can extract 3D rotation information of a character face reasonably.

As the Medical Serious Games are recently proven effective, the quality evaluation of the game has become an important issue. In quality evaluation, objective criteria and evaluation elements are important. Quality evaluation of the serious game is divided into two areas : the technical (from the point of view of Program) and the non-technical (from the point of view of Content). In this study, we developed the quality evaluation element of the non-technical area to the psychotherapy and the health & rehab game according to developing process of quality evaluation model. We extracted five evaluation elements from the two kinds of medical games, and interviewed with medical experts in order to ensure the validity of them. The goodness of fit tests for the elements mentioned above were verified by conducting. Chi-square test results for the two groups did not differ significantly. In conclusion, we expect to take advantage of the results of this study to design and develop serious games for medical treatment.

Three dogs presented to the Veterinary Medical Teaching Hospital of the University of Konkuk and Hangang Animal Hospital with a history of perineal swelling. No tenesmus, stranguria, or any clinical signs other than the swelling was observed by the owners in three dogs. On physical examination, the swelling was observed unilaterally in two dogs and bilaterally in a dog. Digital palpation to the swelling confirmed reducible perineal herniation in two dogs and irreducible perineal herniation in a dog. Plain radiographs revealed that no pelvic or abdominal contents other than the fat were displaced into subcutaneous perineal region in three dogs. Internal obturator transposition herniorrhaphy was performed for correction of perineal herniation in three dogs. Contralateral herniation involving fat was noted after surgery in a dog. The follow-up information was based on physical examination by veterinarians or telephone interview with owners. The owners reported that there was no evidence of complications related to surgery such as sciatic nerve injury, rectal prolapse, wound dehiscence, or perineal hernia recurrence in all dogs.
