Internet makes it possible to access anytime, anywhere learning and so many LMS(Learning Management Systems) serve web based learning. But LMS has not flexible and qualified metadata to offer customired teaming. So we need extensible and flexible techniques which make if possible to define and share advanced teaming metadata. This paper presents an approach for implementing advanced learning metadata in LMS using RDF and the Semantic Web language. So we will first sketch the learning scenario in Semantic Web environment and structure of metadata management. Next we suggest two types of RDF authoring tool and search RDF documents. Advanced metadata management techniques enables the organization of learning materials around small pieces of semantically annotated learning objects. With these metadata learner can customize learning courses, improve retrieval performances.

XML/EDI is different from traditional EDI because it offers the framework necessary for electronic commerce and extends the scope of the traditional EDI which focuses on data transfer. Since existing EDI services are moved to Internet platform and again to Web platform, users can use EDI in the integrated environment without inconvenience of using different EDI softwares, which have their own configurations. This paper describes the overall design and implementation of a Web-based XML/EDI system that is a core component for the electronic commerce. The constructed XML/EDI system in this paper is comprised of document generation module, document storage module, document search module, document management module, template document management module and e-mail transmission module. Requirements and design goal of XML/EDI system are introduced, detailed functionalities of modules and design facts are described and execution and execution procedures of the implemented system are explained.

Due to the proliferation of the Internet and intranet, new application domains such as stream data processing have emerged. Stream data is real-timely and continuously generated. In stream data environments, a lot of queries are registered, and then, the arrived data item is evaluated by registered queries. Thus, to accelerate the query performance, diverse continuous query index schemes have been proposed for stream data processing systems. In this paper, we focus on the query index technique for stream data. In general, a stream query contains the range condition. Thus, by using range conditions, the queries can be indexed. In this paper, we propose an efficient query index scheme, called QUISIS, using a modified Interval Skip Lists to accelerate search time. QUISIS utilizes a locality where a value which will arrive in near future is similar to the current value. Through the experimental study, we show the efficiency of our proposed method.

Data on the Internet are usually represented and transfered as XML. the XML data is represented as a tree and therefore, object repositories are well-suited to store and query them due to their modeling power. XML queries are represented as regular path expressions and evaluated by traversing each object of the tree in object repositories. Several indexes are proposed to fast evaluate regular path expressions. However, in some cases they may not cover all possible paths because they require a great amount of disk space. In order to efficiently evaluate the queries in such cases, we propose an optimized traversing which combines the signature method and block traversing. The signature approach shrink the search space by using the signature information attached to each object, which hints the existence of a certain label in the sub-tree. The block traversing reduces disk I/O by early evaluating the reachable objects in a page. We conducted diverse experiments to show that the hybrid approach achieves a better performance than the other naive ones.

In recent years, as near-duplicate image has been increasing explosively by the spread of Internet and image-editing technology that allows easy access to image contents, related research has been done briskly. However, BoF (Bag-of-Feature), the most frequently used method for near-duplicate image detection, can cause problems that distinguish the same features from different features or the different features from same features in the quantization process of approximating a high-level local features to low-level. Therefore, a post-verification method for BoF is required to overcome the limitation of vector quantization. In this paper, we proposed and analyzed the performance of a post-verification method for BoF, which converts SIFT (Scale Invariant Feature Transform) descriptors into 128 bits binary codes and compares binary distance regarding of a short ranked list by BoF using the codes. Through an experiment using 1500 original images, it was shown that the near-duplicate detection accuracy was improved by approximately 4% over the previous BoF method.

This study examines determinants of film consumption. Using structural equation modelling, this study explores some factors that explained film consumption based on film tastes and information seeking and socio-demographic factors. The major results are as follows: firstly, the major factor for explaining film consumption was individual tastes for films. The higher the degree of tastes for films, the greater the degree of film consumption. Secondly, there were significant relationships between tastes for films and film related information seeking such as internet search behavior and the use of film blogs. More specifically, the use of film blogs partially explained the degree of film consumption. Thirdly, a demographic factor like gender was highly correlated to film consumption. However, an income factor was not correlated to fim consumption. In conclusion, the degree of film consumption was determined by tastes for flims, the use of film blogs and gender factors.

With the new millennium setting in, our society is plowing its way through more drastically changing currents than ever. Nowadays, many people believe that high tech such as the Internet, digital civilization, the IT revolution, bio-industry, and the genome project, that has brought humans material prosperity, is the right change in direction. However, the more we adopt high tech into our lives, the more we desire high touch in order to achieve a balance. In other words, we need something to act as a ballast to stabilize our minds. As such, the more high tech develops, the more individuals miss and search for tools that appeal to their emotions. Because of this, although high touch is an opposite concept to high tech, it coexists with high tech, and it is defined as "human contact of high sensitivity that stimulates the emotion of humans". High Touch, a term which originated from "High Tech, High Touch", a book written by American futurist John Naisbitt, refers to human contact that makes human life richer, forminga deep impression on individuals and providing comfort. As such, high touch, which is gaining significant attention in modern society, is a phenomenon occurring throughout politics, society, culture, art, and religion, together with high tech. Through high touch, modern people must realize how to understand and accept a modern society that is dominated by the age of technology and in which direction they should head. Under this background, this study has the following objectives: to interpret the concept of high touch in the age of high tech in association with formative art and fashion, and through various media examine the desire for expression that may stimulate emotion in modern people, which is required by the high tech-prevalent modern society. It further analyzes how high touch is reflected in modern fashion and presents the direction future fashion should head in.

In this study, I would like to suggest an idal model of web navigation design which can enhance users' web usability. I would like to prove that when users enjoy web navigation design, they access information much more effectively. Using a survey, I suggest some types of web navigation design for users. After that, I conducted an experiment with 4 types of web navigation designs, which have been developed to reflect varying stages of comprehensibility. My survey focused on three points. First I measured the time they spent to search for information. Secondly, I tested whether they lost their way while searching for information and if they did lose their way, I checked whether they could recover from their errors and find their way back. Thirdly, I investigated whether layout, location and size of the web navigation design factors affected usability. The results of my survey indicated that users spend the shortest time, have the easiest interface, and have least error incidence under the web navigation design to enhance old-aged users' web usability. Thus, developing a universal web navigation design can encourage people to be more involved with the internet.

This study aims to survey the perceptions held by students and field workers regarding the clothing-related qualification certificates, which can serve as the base for becoming clothing professionals, to compare and analyze the actual state of qualification certificates on the basic research level, and thus to search for the directions suitable for the clothing-related qualification certificates. The questionnaire method was selected for the study. The responses of 406 copies from students and 81 copies from field workers were used, and frequency analysis and t-test were done with the assistance of spss 10.0 statistics program, The findings are as follows. First, as to the qualification certificates perceived by the students, the certificates of colorist engineer and colorist industrial engineer were known most. 237 students, or 58.4% of the student respondents, had obtained the information about the qualification certificates mainly through the internet and mass media, and 77.3% of the students had a plan to get the qualification certificates. Second, as to the qualification certificates perceived by the field workers, the respondents indicated that school grades(43.2%) would be given the highest additional points at the time of employment, while the clothing-related qualification certificates gathered low responses of 11.1%. The field workers perceived that the qualification certificate of Western suit engineer(pattern) was needed for the job, while 45.4% of them perceived that no qualification certificate was required for the job. Third, both the students and the field workers showed low acquisition levels of the qualification certificates, and in view of their perceptions that the qualification certificates of languages or computer skills were more useful, the improvement is needed in order for the national certificates for the clothing-related skill qualification to develop in the more job-related directions.
