  • This paper examines the ways of using information resources available through information retrieval systems of portal sites. We analyze the types of information resources, search capabilities, and interfaces of Naver, Empas, and Google Scholar. Naver's retrieval system sells research reports, papers, patents information, etc. to users, which is similar to C2C(Customer to Customer in e-commerce environment). Empas provides information from journals, research reports, and proceedings with no charge. Google Scholar's noteworthy efforts are their collaborative programs with and/or for major U.S. libraries, such as "Library Link" and "Library Project." Considering the extended information retrieval services of portals, especially the services like Google Scholar's library programs, libraries need to develop more specialized services, such as the customized information service for individual user, development of user convenience tools like OCLC WorldCat, more accessibility through ubiquitous library concept, and collaboration among libraries.

  • With the development of broadcasting technology from analogue to interactive digital, the number of TV channels and contents provided to audience is increasing in a rapid speed. In this multi-media and multi-channel world, it is difficult to adapt to the increase of TV channel numbers and their contents merely using remote controller to search channels. Due to this reason, EPG (Electronic Program Guide) has been one of the essential services providing convenience to audience. So EPG complying with European DVB-MHP specifications, which will be also our domestic standard, is proposed in this paper. In order to provide audiences with DiTV contents they preferred, we apply collaborative filtering algorithm to recommend contents according to preference value of audience group with similar preference. And we use JavaXlet application which is based on MHP to implement this EPG, while the result can be verified by OpenMHP emulator.

  • As organizations search fur more secure authentication methods (Dr user access, e-commerce, and other security applications, biometrics is gaining increasing attention. Biometrics offers greater security and convenience than traditional methods of personal recognition. In some applications, biometrics can replace or supplement the existing technology. In others, it is the only viable approach. Several biometric methods of identification, including fingerprint hand geometry, facial, ear, iris, eye, signature and handwriting have been explored and compared in this paper. They all are well suited for the specific application to their domain. This paper briefly identifies and categorizes them in particular domain well suited for their application. Some methods are less intrusive than others.

  • In this paper, we design and implement a contest application that enables artists to participate in contest activities, manpower, and job information using smart-phone, and to share and systematically manage the information. While the competition is very important for the artists, it is not easy for them to search the competition information due to lack of time. Therefore, it is effective to provide them with contest information suitable for their interests and to be more immersed in creative activities by sharing them. The core function is to provide a space where artists can share contests in real time through the contest bulletin board and aims to provide a variety of functions for convenient convenience, such as buying and selling of works by artists and spoon market for purchasing materials and art tools do.

  • This study tries to search and analyze empirically the clothing merchandise purchase motivation and behavior made by foreign visitors who bought clothes as tour memorials in South Korea. To make a empirical study we made survey research and evaluated 30 items for the survey of clothing purchase motivation and 25 items for the survey of the importance and satisfaction revealed at the time of purchase with the standard of Likert 5 point. We had chosen 614 sample participants including 176 English speakers, 211 Japanese speakers, and 277 Chinese speakers among those foreign tourists who had purchased clothing materials at the Dongdaemun Shopping Mall. The result of analysis is as follows : As the result of factor analysis about the clothing merchandise purchase, we had 6 factors. They are (1)impulse, (2)utility, (3)fashionableness, (4)tour commemoration (5)psychology (6)economy. As the result of cluster analysis based on the standard of selected 6 factors of clothing merchandise purchase motivation, we could divide three groups such as (1)the pursuit type of clothing merchandise purchase, (2)the pursuit type of recreation of feeling (3)the pursuit type of tour memorial. As the result of analysis on the items of purchased clothing merchandise, the highest frequency of purchase was made by T-shirt, then by the order of sweater, blouse, and aloha shirt, pants, and jacket. In regard to the importance of items related to clothing merchandise, the highest importance was made by design, then by the order of price, size, color and utility, and style. In regard to the items related to the service of shopping mall, the highest satisfaction was made by the convenience of business hour. Meanwhile, the lowest satisfaction was made by the inconvenience of fitting room, the speaking and by ability of foreign languages by sales agents.

  • Background: To evaluate the safety, convenience and effectiveness of 940nm diode laser for treatment of homogenous leukoplakia. Materials and Methods: Ten patients having homogenous leukoplakia which were diagnosed clinically were selected from an Indian dental educational institution for the study. Toludine blue staining was applied locally over the lesion. The area where there was increased uptake of stain was excised using a 940 nm EZLASE TM diode laser (BIOLASE-USA). Results: Although various treatment modalities have been tried and the search continues for novel treatment modalities for complete removal of homogenous leukoplakia, from results of our preliminary pilot study it is clear that the use of 940 nm diode laser as a treatment modality for homogenous leukoplakia is a good substitute. Healing was perfect without any complication within a duration of 1 month. Pain intensity was also mild and absolutely zero on the VAS scale after 1 month follow up. Conclusions: 940 nm diode lasers are safe and can be effectively used as a treatment modality of homogenous leukoplakia, without any complication and without compromising health and oral function of patients. Considering recurrence factor, long term follow up for patients is a must.

  • Recently, consumer who has a desire to spend less money want to buy a cheap and good product because of long economy recession. Secondhand trading is regarded as a good method which allows people to buy cheap and good product. Activation of secondhand trading reduces the psychological distance among customers. Especially, in the case of expensive books such as major books, each university has community only for used book trading. However, existing used book community is hard to find current real-time trading state at a look, and it is impossible to purchase reasonably because of a one-way pricing of the seller. In this paper, we design and implement a used book trading web service using an auction system which can help anyone to trade used book easily. It is designed web based system and it provides convenience to user through efficient book registration function and book search function.

  • In this work, we developed a platform that can monitor status and manage events of factory workplaces by providing events and data collected from various types of multi-touch technology based sensors installed in the workplace. By using the image recognition technology, faces of the people in the factory workplace are recognized and the customized contents for each worker are provided, and security of contents is enhanced by the authenticating an individual worker through face recognition. Contents control function through gesture recognition is constructed, so that workers can easily search documents. Also, it is possible to provide contents for workers by implementing face recognition function in mobile devices. The result of this work can be used to improve workplace safety, convenience of workers, contents security and can be utilized as a base technology for future smart factory construction.
