The purpose of this study was to assess the intra-tester and inter-tester reliability and validity of elbow flexion range of motion using a smart phone used by the general public. Thirty-one general people participated in this study. The range of motion in active elbow flexion was measured with a goniometer and smart phone over two times by two observers. The intra-taster and inter-tester reliability were evaluated using the intraclass correlation coefficient(ICC). The validity was measured by Pearson's correlation coefficient. The intra-observer reliability was good in all measured items ICC>0.900. The inter-observer reliability was high with ICC>0.806. All correlation coefficients of android app and goniometer were greater than 0.868 and showed a significant positive correlation (p<0.01). The range of motion measurement with a smart phone showed acceptable reliability. Therefore, using a smartphone to measure the range of motion of the elbow joint could provide convenience and economic benefits.

In fuzzy expert systems or database systems that have volumes of fuzzy data or large fuzzy rules, the inference time is much increased. Therefore, a high performance parallel fuzzy computing environment is needed. In this paper, we propose a parallel fuzzy inference mechanism in parallel computing environments. In this, fuzzy rules are distributed and executed simultaneously. The ONE_TO_ALL algorithm is used to broadcast the fuzzy input input vector to the all nodes. The results of the MIN/MAX operations are transferred to the output processor by the ALL_TO_ONE algorithm. By parallel processing of fuzzy or data, the parallel fuzzy inference algortihm extracts effective and achieves and achieves a good speed factor.

In this paper, we validate the practicality of the OnePIC app implemented in the previous study by analyzing the execution and storage performance. The OnePIC app is a camera app that allows you to get a photo with a desired focus after taking photos focused on various places. To evaluate performance, we analyzed distance focus shooting time and object focus shooting time in detail. The performance evaluation was measured on actual smartphone. Distance focus shooting time for 5 photos was around 0.84 seconds, the object detection time was around 0.19 seconds regardless of the number of objects and object focus shooting time for 5 photos was around 4.84 seconds. When we compared the size of a single All-in-JPEG file that stores multi-focus photos to the size of the JPEG files stored individually, there was no significant benefit in storage space because the All-in-JPEG file size was subtly reduced. However, All-in-JPEG has the great advantage of managing multi-focus photos. Finally, we conclude that the OnePIC app is practical in terms of shooting time, photo storage size, and management.

The new HDTV technologies provide crystal clear images and surrounding sounds for broadcasting screen in order to serve higher quality of broadcasting. They have four times the resolution of conventional TV and handle 16:9 wide screen aspect ratio images. Due to such technological shift, the function of Character Graphic has been particularly revaluated: it used to be only a subsidiary method to literally deliver visual images, but nowadays it is considered one of the essential elements capable of giving higher values to broadcasting programs. And there is an urgent need for changing its attributes such as fonts, sizes, colors, moving speeds to fit to bigger screen ratio and much more qualified images of HDTV. To meet such a need, Delphi surveys are made twice with three groups of TV production staffs: Art Directors, CG Designers and Production & Transmission team, these groups which are divided on the basis of their roles in broadcasting production process. With the results of these surveys, this article analyzes how all of the attributes of Character Graphic have affected the media users' Visual Perception, and then, suggests a new format designed in OSMU(One Source Multi Use) by which TV character graphics can be properly transmitted to various media formats.

The brand-new small output radio equipment which is over than 800MHz has an all-in-one interior antenna. We suggested new measuring method and developed related equipment because all-in-one radio equipment's performance evaluation requests old way, which is measuring transmitter output and antenna capacity separately, to be changed. That is, origin of small radio equipments with the 360 degree field measured by measuring the TRP, and also 360 degree opposite reception level measured at the radio equipment by measuring the TIS to make a quantitative evaluation was to be. Furthermore, we made managing frequencies, all-in-one radio equipment's best design and capacity management efficiently by measuring the gain of an antenna mounted on a PCB, the circuit around the genetic material, conductive material on the effects of radiation or the reception level.

Feb. 11. 1997, Korean Government announced FM Radio Broadcasting and TV Terrestrial TV Broadcasting will be changed to digital format in year 2001, and all Korean Broadcasting except AM Radio and Microwave will be changed to digital format before 2010. In spite of IMF economic crisis, the Digitizing is the one of the hot issue in TV Broadcasting area. The narrow view of the Digitizing the Broadcasting is a technical development from the analogue to digital, but the extended view of it means not only the technical development but the revolution in the concept of TV and service area, relationship between sender and receiver, structure of TV Industry. Thus Digitizing the Broadcasting shifts paradigm and eventually it cause a big change in the advertising creative. The digital TV could be a very encouraging technical development for the consumers convenience because of the multiple choice in the channels and interactive services which leads us to the multimedia service through the TV . On the other hand, multimedia and multi-channel, interactivity implicate a big uncertainty and risk, This research paper is about the technical aspects and social aspects of digital TV and its influence of the marketing and TV advertising creative.

In this article, Channel 4 in Britain is the main theme since its alternative broadcasting system can shed the light to the Korean case. Korea is getting into the era of multimedia and including webcastings there are over thousands channels are available. However the infra-structure fur the broadcasting contents never seems to be matured to match its need. Instead Korean production system is rather vertically integrated into the Networks(KBS, MBC and SBS) which oligopolise the broadcasting in terms of supply. Even though 'Program Quota Regulation' has been established under the new Broadcasting Art(1999), the old habits die hard and still the independent producers have the unfair relationships with the Networks. Under this circumstance, Channel 4 can be the good example to show how well the alternative system can serve to the diversity of broadcasting and the taste of the minority. Channel 4 took almost 20 years to establish since there were enormous amount of debates about its public missions, ideal broadcasting system, whom it should serve for, etc. between all the social sectors including the independent producers. The social agreement was reached on the point that the new broadcaster should not produce but publish and it is called the 'publishing broadcaster'. In this sense, it can be managed effectively with comparatively little fund and at the same time, it can always have all different sorts of contents as well as genres very freely through 'commissioning process' or buying programs from even the most innovative producers. The 'commissioning process' is one of the key points which makes the Channel 4 so unique. The commissioning process is literally open to anybody, in particular, to the small scale producers with much innovative ideas. Channel 4 will support financially as well as with facilities and human resource to produce the program once after their program idea is accepted by the commissioning editor. Even better side of Channel 4 is about their financial success. From the beginning, the 'funding formula' helped in great deal to make the Channel 4 doing all sorts of innovative experiments. The history of 'funding formula' and its contribution are explained in the article, too. With all this effort, the article is hoped to bring discussion about the alternative broadcasting system which might help to prepare the new era of broadcasting.

Living Lab is one of open movements regarding social innovation, which mainly utilizes scientific technology to improve local residents' life value. Even though various attempts have been made, Living Lab projects that deal with actual life-related problems of local communities are not sufficiently being made. This study aims at organizing existing Living Lab studies and to draw political issues in perspective of solving regional problems and developing local communities. Above all, policies should be proceeded in a way that fully understands and reflects local problem since communication with local residents or end-users will be increased. It is required to support certain products or solution development that fits specific local situation based on their resource and demands. In addition, local small businesses or start-up companies should be given opportunities to conduct experiment and revise new technology, product or service on the spot. It would be a useful example to utilize ICT technology and contents such as local cable TV network, for Living Lab. Living Lab can establish itself as an effective reformation process only if it remains to function for the sake of solving issues of local community and residents. Practical undertones would be able to be obtained once this exploratory study turns into empirical case study.

The paper studied the scheme of applying the MPEG-4 SVC signal to the Ka band satellite broadcasting system through the JSCC system to resolve the rain fading problem generated when providing the Ka band HDTV satellite broadcasting service. The Ka band satellite broadcasting system is based on the VCM mode of the DVB-S2, and the SVC signal is considered as one of the spatial scalability, the SNR scalability and the temporal scalability. The JSCC system jointed all the layers of the source coding system and the channel coding system, and allocated bit rate to source coding and channel coding for each layer to get the optimum receiving quality. The layers are consists of a base layer and an enhancement layer, and the bit rate of each layer is affected by the SVC signal. The applicability of the three SVC signals to the Ka band satellite broadcasting service is analyzed with respect to the rain fading, and the scheme of applying the most excellent SVC to the service is considered.
