Based on local viewers' awareness of locality and consideration of desired local broadcasting service, this study explored the direction of service policy and specific service strategy of local broadcasting. The research method is a secondary analysis using three regional audience surveys and in-depth interview data conducted by KBS. For local audience, the concept of localism is being narrowed down to the city/county/district where they live. In order to reinforce the identity of local broadcasting and improve local broadcasting services, first, the function and role should be expanded to the local mega platform. Second, regional programs such as in-depth coverage and discussion of local issues should be strengthened. Third, in order to communicate with local audience, viewer analysis ability and communication education of local broadcasting members are required. Fourth, it is necessary to create an ecosystem in which local people participate as producers of local broadcasting.

Attempts to embody the three-dimensional world into works have continued without distinguishing between the times and the media, and the purpose is to realize an immersive state rather than the reproduction of reality. It was considered that the flat screen, which is the medium that finally faces the viewer in digital media art, hinders complete immersion, and this study investigated and analyzed the cases of works that give a sense of reality of space beyond the limits of the screen. Using the results of the analysis to produce the work, it was found that the presentation of the realistic space and enhancing immersion in the digital media art field should be viewed not only as visual video content on the screen, but also as an installation suitable for the exhibition environment and the resulting space itself.

Purpose: The number of patients receiving radiotherapy has increased every year and will keep increasing in the future. Therefore, the technique of radiotherapy is developing from day to day, as a result of it, the quantities of image and data used for radiotherapy are also considerably increasing. Therefore, there have been many difficulties in storing, keeping and managing them. Then, we developed and applied this system for improving complicated work process as well as solving these problems with the collaboration Medical Information Team. Materials and Methods: We exported its image at R & V (Record and Verify: Varis vision, Varian, USA) system and planning system after giving some code to be able to access from management system(RO) for department of radiation oncology to PACS. And, we programmed their information by using necessary information among many information included in DICOM head. Results: All images and data generated by our working environment (Simulation CT, L-gram image and internal body structure, DRR, does distribution )were realized at PACS and it became to be possible for clear image to be printed from any computer in department of radiation oncology. Conclusion: It was inevitable to use film during radiotherapy for patients in the past, however, due to the development of this system, film-less system became to be possible. Therefore, the darkroom space and its management cost in relation to the development process disappeared and it became to be unnecessary for spending tangible and intangible financial expense including human resources, time needed for finding film storing space and film and purchasing separate storing equipment for storing images. Finally, we think this system would be very helpful to handle ail complicated processes for radiotherapy and increasing efficiency of overall working conditions.

The 3D printing selective laser sintering (SLS) and stereo lithography apparatus (SLA) method used for bone model production has good precision and resolution, but the printers are expensive and need professional knowledge for operation. The program that converts computed tomography digital imaging and communications in medicine (DICOM) file into STL (stereolithography) file is also expensive so requesting 3D printing companies takes a lot of time and cost, which is why they are not generally utilized in surgery. To produce bone models of fractured patients, the use of 3D imaging conversion program and 3D printing system should be convenient, and the cost of device and operation should be low. Besides, they should be able to produce big size bone models for application to surgery. Therefore, by using an fused deposition modeling (FDM) method 3D printer that uses thermoplastic materials such as DICOM Viewer OsiriX and plastic wires, this study developed 3D printing system for Fracture surgery Patients customized bone model production for many clinics to use for surgery of fracture patients by universalizing with no limit in printing sizes and low maintenance and production cost. It is expected to be widely applied to the overall areas of orthopedics' education, research and clinic. It is also expected to be conveniently used in not only university hospitals but also regular general hospitals.

Artificial lights have effected the changes of art and fashion concepts as well as human life since the invention of electric light bulb in late 19th century. Artist and designer have had more interested in these artificial lights as the development of digital technology and the change of millennium and they have tried to apply the lights into their works. The purpose of this study is to analyze the aesthetic characteristics of contemporary fashion design using artificial light as a medium. Artificial light for fashion design means the light using luminescent material like phosphorescent and fluorescent materials or in combination with electroluminescent digital technology or the light that can be perceived as images when light projects from media using a light projector or other digital equipment. Fashion design using this light type can change colors or form temporarily and it can playa role as a gadget for hm or as equipment to provide information much as a computer monitor does. And designer can create virtual patterns on the surface of clothes, or virtual fashion like a 3-dimensional holography in empty space. In these fashion designs, the virtual image of light is substituted for physical formative elements in fashion, and the viewer can experience an ambiguity between reality and virtuality. The results of the study were as follow; The formative characteristics of those fashion designs were identified as visibility, indeterminacy, integration and virtuality. And they reflected the internal meanings; the persue of protection and safety, the search for experiment and innovation, the will for interaction and communication and the desire for the deviation and fun.

Although the data service of the digital broadcasting has been regarded as the representative service of the broadcasting and communication convergence, it, however, has failed to gain the popularity with the viewers due to the viewer's viewing modality of focusing only on the TV programs. Based on the experts' opinions that the data service should step up so that using a data service while watching a TV program creates a synergy effect, the paper proposes a method for allowing a data service to utilize the information of a TV program. The method has a tool for describing the information of a TV program's content, which changes as time goes on and provides a mechanism for transmitting the information in the way compatible to the digital broadcasting standard. As an application of the method, with a domestic data service developing company, we have developed a ticker data service that shows the information (e.g., actors, places, sponsors, etc.) of a drama.

In a game such as MMORPG, players often see occlusions between primary actors in a shot where shows a close quarter combat. This paper proposes an occlusion resolution technique(MOS) by grafting a medium shot technique and an over-shoulder shot technique to strengthen a confrontation structure. A medium shot technique sets 4 reference points at the up/down/left/right on the sphere of target. An over-shoulder shot technique is a technique of locating the reference points on the side variably. An occluder is replaced with 2 spheres. If a ray is emitted to a reference point from the camera point and intersects a sphere of occluder, it becomes a potential occlusion state. If so, we start to move the camera to the right or left of the occluder, keep moving it while new position of camera is in potential occlusion state, and stop its movement when the occlusion is resolved. Our experiments show that MOS technique consumes operational time of $13.7{\mu}s$ per shot on average, and that it resolves occlusions in 9.26% of ratio on average, and so doesn't have any effect on viewer's sight.

As cable TV networks have a media feature that is a broadband wire network, they can provide not only TV broadcasting services but also communication services. Accordingly, the cable TV network is mentioned as the optimal network for convergence of broadcasting and communication services. Recently, Available frequencies of the cable TV network have become insufficient as enhancement of video quality, increment of VoD service, and growth of high-speed internet service. This paper presents a new implementation method of switched digital video (SDV) technology that is introduced for obtaining additional frequency band. In the SDV system, only TV channels requested from viewer are sent and non-requested channels are dropped. The presented SDV uses a sharing method of TV broadcasting and communication service in a same frequency band. This method shows increase of spectrum efficient from switching of TV service channels without building a complex system.

Information Technology has extended its scope to the medical field as well as dental field. Like medical field, network ststem for dental field requires acquisition, storage, and display of images. However, unlike the medical field, the system to integrate several information including medical images has not been developed according to industrial standard for management of digital image for medical use, so called DICOM conformance. which makes the digital environment in dental field more and more difficult and expensive for this standardization and comfortable communication in LAN and WAN. To solve this problem, the DICOM encoder and server has to be developed because the DICOM file can be easily retrieved with patient's information from the DICOM server in the system as DICOM file has the standard specification to integrate the patient's information. The information including image and other discrete data can be easily integrated in DICOM file and can be used without any difficulty for precise diagnosis and for contribution to the decision making for each treatment protocol. Therefore, the system composed of DICOM encoder and server in dental practive for DICOM file must be developed with prudent consideration of the several strategic factors: I) Enhanced diagnostic capability through the integrated information of image and clinical data. ii) Clinician-friendly interface to simulate the systemic treatment procedure in clinical practice iii) Implementation of multidisciplinary treatment protocol The development of DICOM encoder and server based on these strategic considerations will provide paperless and filmless hospital environments by the seamless integration and management of patient's history, several clinical data and clinical images through image processing for quantitative analysis. The system also allows clinicians to provide more predictable dental care for the patients.
