A high peak power demand at substations will result under Moving Block Signalling (MBS) when a dense queue of trains begins to start from a complete stop at the same time in an electrified railway system. This may cause the power supply interruption and in turn affect the train service substantially. In a recent study, measures of Starting Time Delay (STD) and Acceleration Rate Limit (ARL) are the possible approaches to reduce the peak power demand on the supply system under MBS. Nevertheless, there is no well-defined relationship between the two measures and peak power demand reduction (PDR). In order to attain a lower peak demand at substations on different traffic conditions and system requirements, an expert system is one of the possible approaches to procure the appropriate use of peak demand reduction measures ...

When load areas on a feeder are deenergized due to faults,operaters need to identify nelghboring feeders, try to restore customers and minimize out-of-service areas. These cases include knowledge of system states and various constraints such as voltage drop. This paper concerns the load transfer infault restoration. Also, it is considered the operating constraints such as line current capacity, relay trip current, transformer capacity, voltage drop and line loss. The expert system is able to propose the optimal load transfer method by anallzing system states and considering constraints.

Performed was a survey to find the level of interest on passenger services using IT and smart sensor technology in connection with High Speed Train development in Korea. The survey respondents were sampled from the KTX passengers, KTX crews, Korail employees, IT or sensor experts, and rolling stock experts. The results of the survey were categorized as importance, urgency/necessity, importance vs urgency/necessity, improvement measure, preferable activities based on the trip length, and inconveniencies. By analyzing the results, service items that can be implemented to the High Speed Train were recognized. The results showed that a passenger tends to expect to have his/her comfort and convenience, an attendant safety and serviceability, a Korail employee information provision and serviceability, an IT/sensor expert technological implementation done, and a rolling stock expert implementation done in practical level.

User Generated contents(UGC) interchange with internet users actively in Web2.0 environment. According to growth of content sharing site, the number of non-expert's contents increased. But non-expert's contents have a simple media just recorded. For providing actual feeling like effects and actions to non-expert's contents, we suggest Fusion Media Middleware(FMM). The FMM can increase user satisfaction by providing actual feeling. Furthermore, The content changes advanced media that has emotional impression. The FMM for providing actual feeling classify the inputted media as a scene based on MPEG-7. The FMM provide an actual feeling to simple media by inserting effects like a sound, image and text among the classified media. Using the BSD code of MPEG-21, the FMM can link up with inputted media and effects. Through the mapping BSD code the FMM control synchronization between media and effects. In this paper, Using the Fusion Media Middleware, the non-expert's contents express value as multimedia that has an actual feeling. Futhermore, the FMM creates flow of new media circulation.

This study is to prevent the applicants who apply for the test from being confused by finding problems in the practical test of the bartender certificate and to detect the best way to find out the scoring factors and allotting marks. The goal of this study is to give the direction of proposing the alternative plans of the qualification test for the bartender by the expert group. The questionaries of the survey were sent and collected from June 20 though 30, 2005. After removing some questionaries that have a problem, the survey was conducted for 20 days from August 5, 2005. The samples of the expert group was set up as 50 persons, but 43 samples were available for the final analysis. Also, 7 selected experts proposed the improvements of the marking lists in the practical test for the bartender certificate throughout 2 in-depth studies from September 15 through 25, 2005. According to the analysis, marking lists of the practical test need to be improved. For the detail categories of the practical test, priority appears as follows : sanitation, service and cocktail mixing. For the proper score in the marking lists of the practical test, 25 points is more proper than existing 33 points for selecting ingredients and stools, 10 points is more suitable than existing 9 points for pouring main ingredients, 30 points is more appropriate than existing 42 points for cocktail mixing, 20 points is more proper than existing 10 points for sanitation and 15 points is more suitable than existing 6 points for service.

IPTV contents are based on MPEG2-TS(Moving Picture Expert Group-2 Transport Stream). The Created content is delivered to each home's Set-Top box through the Internet service network, which will be visible on television through the decoding process. The using and spending of content expanding were quite limited in the other existing lines' devices. For this end, provided methods are to convert MPEG2-TS to other format and then transmit it. These methods are causing not only an overload to the system but also its increasing the hardware resource requirements. In this paper, the MPEG2-TS of IPTV's content using RTP(Real time Transport Protocol) provided by the applicable variety of devices and environmental system, was designed and implemented. Through this paper, the existing MPEG2-TS is providing other devices for distribution and consumption that can give better content to the consumers which means that the QoS(Quality of Service) was enhanced. And, the increased consumption and use of content will help the IPTV business to get more development and activation.

Game Industry sustained growth for some time, but the lifespan of a game is shortening. Various efforts to improve the quality of services for the game players which play a role in extending the lifespan of games. When a game is serviced, the server of the game starts to store log informations, and the stored data became important measures to predict game user's activities. As the game's data gathers, it becomes highly useful big data. By analyzing the data of the game stored in this way, a game service issue analysis procedure is proposed to improve the quality of the game service and to proceed with a better service, and based on the analysis in this way, it was applied to the balance test process and verified through expert to the balance test process. If the log analysis process is applied through this paper, it will be a basic data that can improve the quality of game services.

The purposes of this study are to investigate the socialization of household task service area and the satisfaction with it, and to find out the factors affecting on them. For these purposes the data are collected by using questionnaire distributed to 450 housewives living in Seoul. The data are analyzed using frequency, percentile, one way anova, pearson's correlation analysis, simple regression analysis, multiple regression analysis. The results of this research are as follow : 1. There are significant differences in the socialization of household task service area according to housewives's education and employment family income, the type of housing the number of household equipment sex role attitude, attitude about household task, and task performance competency. 2. The factors showing significant relation to the satisfaction about socialization of household task service areas are found to be housewife's education and employment family income sex role attitude and task performance competancy. 3. In the result of the independent contribution of the factors, the most influencial factor is the socialization of household task service area and the next is sex role attitude. 4. Housewives are generally satisfacted on the socialization of household task because of the overweight of household task and because they are unable to those household tasks, and on the other hand they are generally dissatisfacted on the socialization of household tasks because of economic weight, because they couldn't know the ability of service export before employing and because the housework practiced by service expert is different from their expects.
