Movie contents requiring multiple shootings in places need much man power and many equipments. It is more serious in the case of multiple simultaneous shootings. In the points of small broadcasting companies, it is more difficult to cope with the situation, but it is also an essential task for the variety of video contents. We propose an one-person movie production scheme based on an IP camera-based live webcasting system which makes multiple shootings in places possible. It consists of three main functions of (1) collecting multiple video streams sent from IP cameras installed in places, (2) properly distributing them to Internet, and (3) receiving and editing them including recording video. By using the proposed scheme, we can be able to remotely utilize a new framework of Single-Person/ Multiple-Camera which beyonds the conventional Single-Person/Single-Camera framework. It becomes possible to take multiple simultaneous shoots in places. We can get an advantage of saving man power and time for producing various movie contents.

In ubiquitous environment, more small, lightweight, cheap and movable device is used than one device used in wired network environment. Multimedia service which is anytime, anywhere, is provided by device. However, it does not ensure the fair use of multimedia contents and causes damage to the contents providers because of illegal copy and distribution and indiscriminate use of digital contents. For solving this problems, DRM is applied to wired network but it has the problems does not protect stored license and manage license completely because of depending on simple protection such as device authentication and cryptographic algorithm. This paper proposes the license management model using digital forensic and DRM that prevents contents and licenses from distributing illegally and also enables the creation of evidence for legal countermeasure and the protection of license in whole life cycle.

As a demand of mobile network is increasing, mobile support protocols are suggested. Although HMIPv6 managing the micro mobility with MAP suggests a plan for an effectively mobile support, there has a problem of traffic concentrating. This paper propose efficient schemes of distributing the traffic concentrated on hierarchical Mobile IPv6. This proposed schemes, selecting MAP more than two, are divided by selected 'Active' and 'Passive' MAP. The proposed schemes change a state in MAP and define performance to distribute a load in MAP as the Load is occurred by traffic.

Objectives : This paper examines how the Pi(脾) function was understood in the time of the Huangdineijing. Methods : The contents were analyzed and categorized through examining the verses within the Huangdineijing, followed by comparison with a recent publication on the topic. Results &Conclusions : According to the Huangdineijing, there are two major functions of the Spleen. One is producing and distributing Jing Qi from food, the other is managing the Qi cycle of the body. The former function could again be sub-categorized into the part focusing on production and that focusing on distribution. In the Huangdineijing Yanjiu Dacheng(黃帝內經硏究大成, Great Findings from the Study of Hungdineijing) the contents were mostly similar, with the exception of some parts.

In this paper, we develope the smart phone App. contents of 3D sign language to widen the opportunity of the korean sign language education for the hearing-impaired and normal people. Especially, we propose the sign language conversion algorithm that automatically transform the structure of Korean phrases to the structure of the sign language. Also, we implement the 3D sign language animation DB using motion capture system and data glove for acquiring the natural motions. Finally, UNITY 3D engine is used for the realtime 3D rendering of sign language motion. We are distributing the proposed App. with 3D sign language DB of 1,300 words to the iPhone App. store and Android App. store.

A shared work platform is needed to legitimately activate shared works. To facilitate the use of copyrighted works by streamlining licensing procedures and by expressing and distributing the scope of use by authors themselves. In this study, five interface areas and fifteen evaluation items were selected to analyze the interface types and characteristics of the Korean shared work platform, and analyzed based on the national operating platform. We will analyze and compare the situation of the web interface of the Korean shared works by analyzing the types and characteristics of the web interface of the public opera platform, the Gongu-madang, Gonggong-nuri and private leader, Europeana.

Recent IPTV services still remain as simple broadcasting services that cannot make the most of interactive features together with various content-associated data. So, IPTV providers are making efforts to break from monopolistic style, so as increasing the user's participation m service. However there is an interoperability problem because no common solution is employed across different providers. To solve this problem, there needs to be a framework for a framework for generating, sharing and distributing package contents. In this paper, we propose user-centered package contents application framework for interactive IPTV services. We also design a package content authoring and consuming system which plays core parts in the proposed framework.

The discovery of new historical resources is important in that it ensures the sustainability of future researches and enables new interpretations and expansion of them. The purpose of this study is to describe the characteristics of Chinese reports related to the newly discovered Gwangju Student Movement in terms of contents. In particular, since Chinese reports contain the same expressions and contents, we tried to figure out which materials from Korea and Japan were cited the same and what kind of relationships there were. The analysis results are as follows: First, the relationship between the reports on December 6, 1929, which were newly claimed as the first reports, and the Gwangju Student Movement was explained in detail. Although there is no specific indication that the distributing of manifesto and arresting case on December 6th in Seoul was related to the Gwangju Student Movement, it should be viewed as the first reports made to support it. Second, in previous studies, it was revealed that the contents known as the newspaper's own reports were actually quoted from previous reports in Korea or Japan. Third, it was confirmed that the contents of reports could be affected by the citation reports according to the political characteristics of the newspapers.

The vehicle lubricant occupies upto 35% in a total lubricant market and engine oil occupies upto 77% in the vehicle lubricant market in Korea. A suitable quality management of the circulating engine oil is necessary for driver and engine protection. But, KS and synthetic engine oil products (involved over 30% synthetic oil) are exempt to any quality management under Petroleum and Alternative Fuel Business Act. It is also known that synthetic oils such as PAO (poly alpha olefin) have excellent properties and performance like anti-wear, varnish control and oxidation stability than those of mineral oils. For this reason, PAO has been used for an engine oil, rotary screw and reciprocating compressor in addition to heavy duty and other extreme service applications. In this study, our research group analyzed the chromatogram pattern for the mineral oil, PAO and mineral oil involved a typical ratio of PAO using SIMDIST (simulated distillation). In the SIMDIST chromatogram, the mineral oil showed a broad peak, while PAO showed a sharp typical peak. Also the oil with a large viscosity grade exhibited a long retention time due to the heavy molecular weight and high boiling point. In particular, the blended mineral oil with 20% PAO sample showed a distinctly different pattern compared to that of using the conventional mineral oil. For monitoring PAO contents in distributing engine oils, we analyzed the SIMDIST for 27 kinds of engine oils which were popularly sold in Korea. The analytic results indicate that all kinds of engine oils showed that PAO contents were below 20% in engine oil products. Moreover, the PAO titled product was found to have a small amount of PAO. Thus, we conclude that the related laws for the proper quality management of synthetic oils are needed to be established.
