This study was to investigate the concept of ISNI and to find its availability in authority control, realizing importance of ISNI as the bridge identifier including all the information media content industries. ISNI is needed for global and comprehensive name authority control as the bridge identifier for the identification of public identities of parties involved throughout the information media content industries in the creation, production, management and content distribution chains. First of all, it was to inquire ISNI concept, goal, terms and definitions, structure and syntax, allocation of ISNI, administration of the ISNI system, and metadata. Next, it was to suggest the applicability of ISNI in authority control. First, it should be needed to consider in applying ISNI for cooperative authority control. It is possible to interactively use the authority data created in library and other information industries area by constructing KISNI system. Second, it is possible to construct linked data by linking various identifier through ISNI identifier as bridge identifier. Third, it is needed to develop KORMARC for describing ISNI identifier in KORMARC bibliographic and authority record.

Recently, the distribution and using of the digital multimedia contents are easy by developing the internet application program and related technology. However, the digital signal is easily duplicated and the duplicates have the same quality compare with original digital signal. To solve this problem, there is the multimedia fingerprint which is studied for the protection of copyright. Fingerprinting scheme is a technique which supports copyright protection to track redistributers of electronic information using cryptographic techniques. Only regular user can know the inserted fingerprint data in fingerprinting schemes differ from a symmetric/asymmetric scheme and the scheme guarantee an anonymous before re-contributed data. In this paper, we present a new scheme which is the detection of colluded multimedia fingerprint by neural network. This proposed scheme is consists of the anti-collusion code generation and the neural network for the error correction.

This study looks at 'Corporate Social Responsibility' which is required for the fashion industry and brands in modern times. The American fashion brand known for its corporate social responsibility activities, 'Patagonia' is the case study for this research. The purpose of this study is to make suggestions to eco-friendly, outdoor and casual apparel fashion brands that want to introduce corporate social responsibility programs by considering the case of Patagonia's "Worn Wear" campaign. The method of this study was to review corporate social responsibility, previous studies on Patagonia, and literature, such as domestic and foreign media, Patagonia's official homepage, specialty publications, and media. The study concerning corporate social responsibility is focused on Patagonia's "Worn Wear". Worn Wear is Patagonia's system that repurchases and repairs products from Patagonia's own consumers. The study found that the well known corporate social responsibility led to increased sales. Patagonia's social responsibility activities are thought to be part of the brand identity that goes beyond marketing. In the Worn Ware case, repurchasing products from consumers and reselling them or reprocessing them resulted in increased sales, increased consumer engagement, and higher brand attention. The suggestion for a fashion company or brand in a category similar to Patagonia that is looking to engage in corporate social responsibilbty is to adopt and continue a campaign that 'consists of a successful marketing image, connecting memories and new experiences, separated shopping channels while diversifying the creation of distribution and contact channels'.

Presence, flow, and arousal are interesting user experiences provided by video and people's demand for media which responds to personal interest is getting strong. This research compares video watching and game play by conducting a survey and measuring brain wave to find out the difference of those user experiences in the two media. As a result, all the three user experiences were proved to be significantly higher in game play than video watching. And those EEG frequencies which are known to be related to the state of flow were also measured higher scalp distribution of the game play group. Finally, presence, arousal, and EEG(${\alpha}$, ${\beta}$, ${\delta}$) were found to have influence on the flow state in game play. This research is intended to prove above relations by experiment and make a contribution to the theoretical and methodological improvement in the related area.

The cultural caracteristics of Monosporascus cannonballus causing root rot of Cucurbitaceae plants were examined in vitro, and population density of the fungal ascospores were measured and compared aoming diferent host species and soil depths. Potato-dextrose agar(PDA) was the most appropriate medium for the mycelial growth and perithecial formation among the 5 media tested. Corn-meal agar(CMA), oat-meal agar (OMA) and V-8 juice agar were moderate media for the mycelial growth and perithecial formation, whereas water agar(WA) was poor medium. Perithecia were not formed on WA. Optimum temperature for the formation of perithecia was about 25 to 30$^{\circ}C$. distribution of ascospores in the infested fields was variable amount the curcubitaceae plants and within the same plant species, ranging from 1.7 to 14.6 ascospores in 20 g of soil, but no ascospore was detected in the uninfested field soils. Ascospores were distributed more at 20cm of soil depth than at 10cm or 30cm of soil depth.

This paper presents an efficient approach to build an image mosaics from image sequences. Unlike general panoramic stitching methods, which usually require some geometrical feature points or solve the iterative nonlinear equations, our algorithm can directly recover the 8-parameter planar perspective transforms. We use four quasi-feature points in order to compute the projective transform between two images. This feature is based on the graylevel distribution and defined in the overlap area between two images. Therefore the proposed algorithm can reduce the total amount of the computation. We also present an algorithm lot efficiently matching the correspondence of the extracted feature. The proposed algorithm is applied to various images to estimate its performance and. the simulation results present that our algorithm can find the correct correspondence and build an image mosaics.

The characteristics of microwave reflectometry, which is based on the technologies of FM radar and is applied as a non-invasive method to examine the properties including density distribution of inhomogeneous media, is investigated. The microwave reflectometry system requires not only an optimized system hardware but as well as the understanding of system response from the media under test in order to provide the system solution describing the object under test quantitatively. The introduction of microwave reflectometry especially in the area of applied plasma physics has been relatively new and the number of usage is found to be increasing gradually. The experimental method to characterize the microwave system as a device to examine the properties of plasma is explained. The microwave reflectometry signals consist of the cutoff signals which originate from the region where most of the reflected power comes from and the scattered signals which result as an interaction of the microwave and the density perturbations. This paper describes the experimental results of the scattered signal from the microwave reflectometry, such as the wavenumber dependence and the sensitivity on density perturbation, and the comparison of the characteristics with those from the numerical simulations and those from the cutoff signals.

The purpose of this study is to identify the supply status and planning trend of North Korean housing through analysis on the North Korean architecture specialized media data. The flat composition is changing and the living room is becoming the center of the houses. Also, in the urban areas, the standard apartment type is four apartments in a row and the plan form is getting diversified into circle type, Y type, and irregular type. On the other hand, in the rural areas, two houses in a row and single house are typical and the change in planning scale and space structure are not substantial. Since the 2000s, design changes have been made to emphasize the third dimensional structure of buildings such as the elliptical houses and L-shaped houses. Furthermore, 8~10 households are located on one floor which leads to the tendency of the building enlargement. In terms of house size, a square concept was introduced to replace the initial 2~3 room concept and the basic module of the room planning the 3 room house based on $3m{\times}3m$. However, there seems to be no standard house size, and the house size may differ depending on the social classandregion. In the early 1980s, when there was focus on the apartment complex construction, the high-rise apartment buildings of 30~40 floors was planned. However, during the Pyongyang redevelopment project, apartments of more or less than 10 floors were built and row-houses of more or less than 4 floors were built. In terms of the complex scale, a lot of small complexes of around 300 households are emerging after 2010. The construction projects are mainly limited to specific regions such as Pyongyang and Samjiyeon, and also limited to specific classes such as the workers and soldiers initially and the scientists lately. In addition, living boundary composition and ancillary facilities for sufficient green area ratio securement and the people of North Korea are maintained consistently. In recent years, the specialized floor planning such as solar house and the house for the disabled people, framework houses for redevelopment business, and multi-storied house construction technology are also emerging.

Due to illegal copying and distribution via the internet, the digital media that have been introduced create certain intellectual property issues. Because of this, several intellectual property groups have been created to create and maintain Digital Rights Management systems (DRM), in order to crack down on illegal and unauthorized copying. However, these systems are often created by many different companies, which leads to problems of interoperability. Despite attempts to regulate DRM systems, including the MPEG group's Intellectual Property Management and Protection" system, the system is still struggling to maintain some sort of interoperability between differing protocols. In this paper, we designed and implemented a DRM system with Gstreamer, following the DMP.
