Information sharing behavior in the Internet has raised much interest. Recently, social network sites provide a new information sharing channel for the users who want to connect with others based on common social background or tastes. Especially, we focus that a social network site becomes one of major routes for information sharing about socially influential issues. Therefore, studying how information is diffused via a social network site may give theoretically, practically significant implication. Based on the assertion, we investigated user's behavior to mediate other user's information messages. We define information mediating behavior as concurrent actions of filtering and distributing behavior of the digital content that is originated from one of the connected users. In this study, we intended to understand the effects of information mediating behavior, and tried to understand characteristics of re-mediating of previously mediated information. Using an agent-based simulation model, we found that information mediating behavior increased the extent of information diffusion significantly. In addition, even a small degree of mediating probability could boost up the level of information diffusion in the case of a re-mediating condition. We believe that those findings provide remarkable insight of research and business application on both of information sharing and diffusion in a social network site.

Since a 'Well-being' theme had become an issue in 90's, everyone now care about their health more than ever. Besides, IT has been developed so tremendously that we have various ways to collect up-to-dated information through the internet. There are so many web sites that contain information about health and diet. However, the menus of these web sites are not simplified and the content is too large, so the information we see in those web sites may not be accurate. Also, some information is out-of-dated. In this paper, we propose a web site called 'Calory&Diet' that provides customized information on diet. The characteristics of the web site are as following: First, the menu is so simple that users can easily find information they want. Second, it only provides necessary customized information. Lastly, it uses an open application that helps users always get the latest information without DB updates. With its user friendly menu and feedback information, the proposed web site can be a good advisor for people who want to be healthy. 100 offers the user survey results than existing systems, simple system to 2%, 3% from a custom-related topics, the latest related topics were 3% higher on 5 point scale.

This paper is the study on the Medium Designator in Non-book materials. Main contents of this study were as follows; 1. The medium designator serves to indicate the class of material to which an item belongs. This is used to give an 'early warning' ;to the catalogue user. 2. This medium designator may be further divided into two elements ; a general material designation (GMD), for example video-recording, and a specific material designation (SMD), for example, videodisc. 3. GMD: In cataloging, a term indicating the broad class of material to which a bibliographic item belongs, such as 'motion picture', and SMD : In descriptive cataloging, a term indicating the special class of material (usually the class of physical object) to which a biblographic item belongs, such as videocassette. 4. Locating the medium designator after the title proper was not prescribed until ISBD(G) and AACR2. In pre-ISBD(G) codes, the ,early, warning type of medium designator was placed after all title information. But in AACR2, the medium designator is placed after the title proper, but before parellel title and other title information. 5. In Terminology, Two separate lists of designations are given in AACR2, l.1C1, one for British and one for North American use. The British list contains fewer terms, and uses generic categories to group together some of the North American list. 6. The problem of where to place the medium designator might be circumvented by using some kind of early alerting device other than a formal element of biblliographic description. Various alternatives have been suggested. A more popular device is the provision of symbols or 'media code' which are part of the call number and indicate the porticular medium type. 'Colour-coding' the use of used by some libraries but is now longly discouraged. 7. According to Frost. The medium designatorhas been generally reeognized as serving three functions; 1) as a statement of the nature or basic format of the item cataloged and thus as a meant of informing the user as to the type of material at hand; 2) as a description of the physical charaetistics of medium and as a means of alerting the user to equipment needed to make use of the item. 3) as a device to distinguish different physical formats which share the same title. 8. AACR2 raises some problems which decision makers have neet had to face preriously It provides a GMD for every item in the collection including books and it makes the application of any or all GMD's optional.

The computing systems of today expanded business trade and distributed business process Internet. More and more systems are developed from components with exactly reusability, independency, and portability. Component based development is focused on advanced concepts rater than passive manipulation or source code in class library. The primary component construction in CBD. However, lead to an additional cost for reconstructing the new component with CBD model. It also difficult to serve component information with rapidly and exactly, which normalization model are not established, frequency user logging in Web caused overload. A lot of difficult issues and aspects of Component Based Development have to be investigated to develop good component-based products. There is no established normalization model which will guarantee a proper treatment of components. This paper elaborates on some of those aspects of web application to adapt user requirement with exactly and rapidly. Distributed components in this paper are used in the most tiny size on network and suggest the network-addressable interface based on business domain. We also discuss the internal and external specifications for grasping component internal and external relations of user requirements to be analyzed. The specifications are stored on Servlets after dividing the information between session and entity as an EJB (Enterprise JavaBeans) that are reusable unit size in business domain. The reusable units are used in business component through query to get business component. As a major contribution, we propose a systems model for registration, auto-arrange, search, test, and download component, which covers component reusability and component customization.

Recently in the field of information design use of multimedia Including animation has been rapidly increased. And its application is expanding in the field of design nevertheless relevant research in this field is scant. In particular research on which characteristics contribute to improvement for effect of information communication is negligible. Until now designers' interest was mainly focused on visual perfection of screen such as diversity and originality. Actually the aspect of recognition of design was mostly overlooked. But considering ultimate purpose of Information design is accurate communication of information thus there should be more endeavor for research on man's visual recognitive faculty and memory in order to Improve power of communication of information for the purpose of reducing confusion of user before its originality and diversity. For this reason this author in this treatise attempted to examine possible impact of multimedia in information design on recognition of user and communication based on theory of effectiveness of media and also attempted to identify how maximize its effect under different circumstances. Theories on effectiveness of media can be summed up as that well- advanced information of multimedia should be analysed from diverse standpoints on relevancy to tasks and recognitive relevancy rather than its simplification from the standpoint of richness of media. For optimal interface design unnecessary recognitive load should be eliminated and information should be structured by laking maximum advantage of working memory of limited quantity. Also there will be need for selection of proper media and suggestion of expressive method to enable building accurate and successful mental image. In this treatise this author attempted to contribute to designer's decision making in future through examining theories on effectiveness of media in connection with the question of which information technology should be used in order to heighten effect of information communication appropriate to information design.

In ubiquitous computing environments, users want to receive the robot services regardless of various physical status or devices such as time, place, various sensors, and high-performance servers. Thus, the ubiquitous service robots have to provide users with automated services according to situational information that they properly recognize. Beyond these problems, robot software has to establish a foundation to support the functions with the network infrastructure that are not able to be solved by a single independent resource. On the basis of a robot middleware that is capable of minimizing dependencies among hierarchy structures, the robot software also has to provide execution environment to control the flow of robot application services. In this paper, we propose a layered architecture to provide users with automated services through ubiquitous robots. The proposed architecture is based on CAWL (Context-Aware Workflow Language) and RSEL (Robot Services Execution Language). CAWL easily represents the flow of robot services from user application service levels, and RSEL is able to support the composition and reusability of robot services through abstraction of robot device services. In our experiments, we applied the proposed architecture to an example of "booth guide robot service".

This paper introduces the parking guide service developed to address the inconvenience of parking in areas where demand for parking spaces is high, such as busy streets and tourist attractions. Due to difficulties in measuring and developing the actual parking lot while driving the car, we created a temporary parking lot and created Arduino RC Car to replace the actual car. Video processing based on Open CV allows users to identify the entire parking lot, parking space, and completed parking space, and track moving cars, and this information has been developed to enable users to see through the application. The application allows the user to book the desired parking space and introduce a way-finding algorithm to guide them through the optimal path to the selected parking compartment.

A middleware in grid computing environment is required to support seamless on-demand services over diverse resource situations in order to meet various user requirements [1]. Since grid computing applications need situation-aware middleware services in this environment. In this paper, we propose a semantic middleware architecture to support dynamic software component reconfiguration based fault and service ontology to provide fault-tolerance in a grid computing environment. Our middleware includes autonomic management to detect faults, analyze causes of them, and plan semantically meaningful strategies to recover from the failure using pre-defined fault and service ontology trees. We implemented a referenced prototype, Web-service based Application Execution Environment(Wapee), as a proof-of-concept, and showed the efficiency in runtime recovery.
