Information technology and tourism seem to be very unlikely parterners. In so far as the technologies are concerned, it is not telephone or computers or videotext that are being diffused, but a whole system of information technologies. Indeed information and the technologies for their manipulation, are vital cement of the tourist trade. The objective of this study is to aggregate and analyze the development and theoretical constructs which could offer a more profound understanding of the diffusion and impact of information technology in the tourism marketing strategies. Such an approach could help to alleviate some commonly-held misconceptions about information technology and tourism industry.

The number of tourists is increasing, and it is researched that the majority of them make a reservation directly through on-line travel service on their own, not through travel agencies. Internet is absolutely needed in the tourism business, many travel agencies, hotels, and airlines offer the information and service about tourism to tourists by establishing their home pages. Korea travel agencies Internet-maketing is still on the primary stages, when it compared with international trend. This study shows Internet is significantly related to travel business, but many tourism companies utilize Internet as advertisement method and corporate image and it is not used very well in terms of facility or corporate circumstances. In the near future, the importance and efficiency of Internet will be increased through generalization of inte;, and the development of recognition about the importance of mass media.
Formation of Nanoporous Pt Thin Films by Electrochemical Dissolution
김천중,박예준,남창우,박병우 대한금속·재료학회 2008 ELECTRONIC MATERIALS LETTERS Vol.4 No.2
To study nanoporous formation by electrochemical dissolution, Pt0.52Al0.48 thin films were examined during 500 repeated cycles. Although the Pt0.52Al0.48 thin films exhibited similar electrocatalytic properties to Pt thin films at the initial stages, the Pt0.52Al0.48 thin films showed gradually increasing electrocatalytic properties as cycles proceeded. These enhancements are attributed to the nanoporosities in the Pt0.52Al0.48 thin films. The nanoporous Pt thin films, after the complete dissolution of Al, exhibited approximately one order of magnitude larger electrochemical surface area than Pt thin films. Superior methanol-oxidation activities were also observed in the nanoporous Pt thin films.
관성항법장치 위치 측위 기법 및 측위 위치정보 이용 칼만 필터 기반 자체정렬 성능 분석

This paper presents indirect and direct positioning methods that acquire the initial position information necessary for self-alignment using an INS (Inertial Navigation System) in an environment where positioning information is not available and external interfacing to the INS is not possible. The performance analysis results of the self-alignment based on Kalman filter using the positioning information obtained by the proposed methods are also presented. The proposed positioning methods and self-aligned performance analysis results are verified through simulation and test. The verification confirms that the direct positioning method has excellent accuracy while undergoing external angular motion, and that the alignment performance is not significantly reduced, even when the positioning information is used for self-alignment. Therefore, if the INS is operated using the method presented in this paper, we expect that the operability of the vehicles equipped with the INS will be greatly improved. .
관광정보기술 적용에 관한 연구 : 호텔정보시스템을 중심으로

In this article, I have a purpose to research the applied condition of hotel information system in Korea to see how IT(Information Technology) which is required to process tourism information precisely and efficiently is applied to tourism industry and then suggest the direction of development of hotel information system application. The survey was practiced on 13 first class hotel in Seoul, Korea, from September 27 to October 7 by mainly fax and telephone. As a result of this research, I think that the hotels in Korea still have many things to do, applying information technology. Especially IT should be applied for the work connection among departments in front office and in back office as well as between front office and back office to achieve an entire harmony.
