Lee, Jae-Eun ; Kim, Young-Moon ; Lim, Chan ; Kang, Hyun-Soo ;
The Journal of the Korea Contents Association, volume 7, issue 8, 2007, Pages 1~12
DOI : 10.5392/JKCA.2007.7.8.001
This paper presents a new demixing method that separates each source from a stereo sound mixture. Under the W-Disjoint Orthogonal assumption in DUET(Degenerate Unmixing Estimation Technique) algorithm. The proposed method is mainly processed in time-frequency domain by using windowed-fourier transform. In this paper there are two main contributions: a weighted mask by panning index distances and a binary mask by comparing each channel value. The former has tender demixing characteristic, and the latter has stronger demixing characteristic. In experimental results, we will show that both masks produce more robust demixing than the existing demixing methods do.

Decision tree is one of the most useful analysis methods for various data mining functions, including prediction, classification, etc, from massive data. Decision tree grows by splitting nodes, during which the purity increases. It is needed to stop splitting nodes when the purity does not increase effectively or new leaves does not contain meaningful number of records. Pruning is done if a branch does not show certain level of performance. By pruning, the structure of decision tree is changed and it is implied that the previous splitting of the parent node was not effective. It is also implied that the splitting of the ancestor nodes were not effective and the choices of attributes and criteria in splitting them were not successful. It should be noticed that new attributes or criteria might be selected to split such nodes for better tries. In this paper, we suggest a procedure to modify decision tree by Fuzzy theory and splitting as an integrated approach.

Due to the growth of embedded systems and the development of semi-conductor and storage devices, digital convergence devises is ever growing. Digital convergence devices are equipments into which various functions such as communication, playing movies and wave files and electronic dictionarys are integrated. Example are portable multimedia players(PMPs), personal digital assistants(PDAs), and smart phones. Therefore, these devices need an efficient file system which manages and controls various types of files. In designing such file systems, the size constraint for small embedded systems as well as performance and compatibility should be taken into account. In this paper, we suggest the partial buffer cache technique. Contrary to the traditional buffer cache, the partial buffer cache is used for only the FAT meta data and write-only data. Simulation results show that we could enhance the write performance more than 30% when the file size is larger than about 100 KBytes.

DOI : 10.5392/JKCA.2007.7.8.059
Overlay Multicast is an effective method for efficient utilization of system resources and network bandwidth without a need for hardware customization. Multicast tree reconstruction is required when a non-leaf node leaves or fails. However frequent multicast tree reconstruction introduces serious degradation in performance. In this paper, we propose a tree performance optimization algorithm to solve this defect by using information(RTCP-probing) that becomes a periodic feedback to a source node from each child node. The proposed model is a mechanism performed when a parent node seems to cause deterioration in the tree performance. We have improved the performance of the whole service tree using the mechanism and hence composing an optimization tree. The simulation results show that our proposal stands to be an effective method that can be applied to not only the proposed model but also to existing techniques.
Effective Network Management Using Mobile Agents Based on Split Management Policy
Lee, Jae-Hyoung ; Oh, Gil-Ho ;
The Journal of the Korea Contents Association, volume 7, issue 8, 2007, Pages 66~75
DOI : 10.5392/JKCA.2007.7.8.066
The traditional centralized network management method using the SNMP has problems, such as, increase of communication traffic and severe bottleneck phenomena at the specific manager-node caused by a frequent polling mechanism. Several mobile agent based network management methods have been studied to solve and overcome these problem. However, in these mobile agent based methods, as the number of nodes to be managed is increased, the mobile data are increased accumulatively and the effectiveness of the network management is decreased. In this paper, we propose the split management method by using mobile agents to handle these problems. In our method, the nodes are divided into groups to be handled by separate mobile agents. Each mobile agent visits its own nodes and gets management information from them. We demonstrate the effectiveness of our proposed method using experimental results.

The Journal of the Korea Contents Association, volume 7, issue 8, 2007, Pages 94~101
DOI : 10.5392/JKCA.2007.7.8.094
In this paper, we propose a surveillance system using multi-person tracking in a WIPI based mobile system, which is the standard wireless internet platform. The proposed system consists of two subsystems: the person tracking system and the mobile information transmission system. The person tracking system tracks persons who invade security and the mobile information transmission system sends the tracking results from the person tracking system to the user`s mobile phone. In this paper, the person tracking system tracks persons who appear on many cameras with non-overlapping views in order to achieve a wider view. The mobile information transmission system saves automatically tracked data to the owner`s web server and transmits the saved data to the user`s WIPI mobile phone. Therefore, whenever the user wishes to view tracked data later, the mobile system can provide the user with the tracking results by either the user selecting particular cameras or the time on the owner`s mobile phone. The proposed system is a new surveillance system that transfers tracked data among cameras to the user`s mobile phone in order to overcome space limitations in tracking areas and monitoring areas and spatial limitations in monitoring hours.

The one-person producing system is that planning program, arrangements, composition, taking pictures and edition are all done by only one person. In the reality of the producing systems of the broadcasting programs, as the number of the broadcasting stations, which apply one-person producing systems, is gradually increasing, the study on the change is going on. In this study I grasped the merits and demerits of both systems ; multi men producing system and one-person producing system. And then I analyzed the sudden change of the method of the producing programs into one using the 6m digital camera. The merits of producing programs by means of the 6m digital cameras are following ; the mobility of producing programs, a close contact with the source, the enlargement of the diversity of the contents and cutting down expenses. The demerits of it are following ; a lowering of the degree of completion and the unstableness of an image. Nowadays because of the enlargement of the rate of the outsourcing production, the number of the independent production studios rapidly increased. From the viewpoint of cutting down expenses and the diversity of contents, the number of broadcasting programs produced by means of one-person producing broadcasting program system is increasing.
Representation of Time within Film Narrative -Focusing on
Lee, Jee-Heng ;

While films today offer spectacle to the viewers due to the advanced technique, the "Modern Cinema"-a term named by Deleuze- offers spectators an opportunity to think about what they observe and to have various filmic experiences through the shifting of time image within the film narrative, which has been rather neglected as it is just a form in the realm of classic narrative. Originally the shifted time image was a result of thinking about the identity of a film. But it has self-reproduced over and over, and now it has turned into one of cliches that narrative films take. In this sense, a Korean Melodrama "Sarang-ni" is discriminated from other films which take twisted time image as a convention. The film "Sarang-ni", instead of adopting established shifted time image, put us to the confused time arrangement and then it amazingly arouses emotional effect which it initially meant to convey. This journal analyzes how the time representation of
operates in the film`s narration, and consequently how the form affects the storytelling.

As part of city marketing, many local governments are recently developing or have already developed a slogan for their own city brand. This study aims to provide basic source materials for an efficient and more systematic way in current development of the slogan for a city brand. Therefore, this study compared and analyzed the cases for developing the slogan for a city brand in Korea and in other nations, presenting some feasible solutions. As for the characteristics of the slogans for city brands in Korea, they were all campaign-type slogans with a single-component structure that includes the city`s name. They mostly used values as their subject material. The basic requirements for producing a successful city-brand slogan include the emphasis on the quality of being unique and differentiated. A city-brand slogan must incorporate the kind of natural environment, the culture, the history, etc that are unique to the region in order to become a creative and unique slogan. Rather than being swayed by short-term trends, a city-brand slogan must have a long term vision and strategy as well as a clear and accurate setup. Also, a city-brand slogan will proliferate and create values as a brand when shared communications with all local residents continue to occur after developing the slogan.

Virtual world is the 3D graphical interactive environment that networked by electronic communications. Virtual Worlds offered flow experience for a long time to their users. They blur the boundaries of work and play, so bring out the concept of Fun Labor. If we can accept the principle of equivalence between Fun Labor and Real Labor, the Fun Labor may be one of the solutions of the large unemployment problem in the information society. And the Fun Labor is the new type of labor that corresponds the subjectivity of users who want interesting experience as much as they spend money and times. This situation means that the users of Virtual worlds are structuring the identities as the Residents who act the Fun Labor. It`ll be very important to examine the social effects of this situation.

Capital gain comes from the transfer gain which is occurring by transferring assets except inventory assets. Our government recently has made capital gain tax on real estates and imposed as classified income tax by including it into aggregate income so that provide function of tax and curb property speculation. However the present income tax law imposes capital gain tax on capital profit including real estate and securities, while this law and the special tax treatment control law implement non-taxation and tax exemption too widely. That is to say, the system of capital gain tax can hinder the fair tax because it has various exemption terms including the non-taxation principle on a house for a family and the special tax treatment law. And also it has a problem in the sense of equity because it imposes tax by progressive tax rate on the subjects of capital gain tax considering them as the profit of that year, which were transferred, so there is difference between the income which has been made for a long time and the income made for a short time even in the same capital gain. Therefore this study identifies some issues surrounding the present capital gain tax system and focuses on presenting reasonable development plan.

Both competent authorities and private entrepreneurs face plenty of risks when negotiating BTO(Build Transfer Operation) methods of PPI(Private Participations in Infrastructures) projects. Also, success and failure of projects largely depend on the concession agreement contract. In this study, for more efficient negotiation, major issues are examined, and quantitatively analyzed to find out not only the relationship but also the characteristics of which these issues share. Questionnaire research was conducted through both research and by experts who were divided into an ordering agency, design company and constructor. Characteristics of major issues were quantitatively analyzed using the Likert index method, ANOVA(ANalysis of VAriance) and AHP(Analytic Hierarchy Process) analysis. Case studies were examined in order to estimate construction cost, rates of return, government finance support, level of operation-revenues guarantees, estimating operational costs and usage fees. With these 6 items, relative priority, relative impression which is sensible to risk and extent of difficulty in presenting data which is objective were quantitatively analyzed by the ordering agency, design company and constructor groups. From the analysis, there were some similarities between the design company and constructor groups while there was less of similarities between the ordering agency and design company or constructor. The government is diversifying the methods of project promotion, and PPI project from infrastructure-centered to public culture facilities are being expand. The current study will provide not only supporting efficient negotiation but also revitalizing PPI projects.
