This study implements library toolbar in order to improve the accessibility of OPAC in the library. The toolbar elements are extracted on the basis of the importance of functionality for OPAC. After comparing the toolbar implementation approaches, this study develops the library toolbar with these elements as the client-based application that can fully realized the functionality of the toolbar. The librarians evaluate the usability of toolbar very affirmatively. This study also summarizes the further functionalities to upgrade toolbar proposed by the librarian. Through deploying the upgraded toolbar, the user requirements have to be analyzed and realized with the user survey.

As the number of functions in a menu increases, users have more difficulties in finding a desired function. Previous studies have shown that some functions are selected more frequently than others, and have suggested adaptive menus that support the selection of frequently used functions. Interestingly, studies on an adaptive toolbar are not easy to find as opposed to many studies on adaptive menus. This study suggested an adaptive toolbar (AT) that supported function selection, and conducted a usability test. Five or ten functions were presented in the AT according to the frequency of use or recency of use. A total of sixteen males in their twenties participated in the test. They freely selected functions from the menu or from the AT, and their pattern of selecting functions was analyzed. The results showed that the AT was more frequently used than the menu as time passed. The AT based on the recency of use showed more effective performance than that based on the frequency of use. In addition, keeping ten functions was better than five functions in terms of both performance and preference.

University library users prefer the internet to OPAC, when they search for information. It is necessary to develop interface of OPAC that is nearly as convenient as the internet. This study provides users with University Library Toolbar which is one of the ways to implement Web 2.0, and proved that OPAC is also a convenient and useful searching tool by offering the toolbar. In addition, the causes of the preferences of the internet sites surveyed for this study and the point shown in the comparison between the internet and OPAC are going to be essential materials to implement more convenient OPAC and Library 2.0.

The present study employed an experimental usability testing technique to explore cognitive engineering characteristics of WWW. Based on the results of our previous study which employed non-experimental methods such as questionnaire and heuristic evaluation method, this study used a behavioral performance-measurement technique to evaluate the usability of a domestic web-site design. Specifically, we revised the menu and document structure of the original 'Movie-Friend' site to solve the design problems which were extracted from the results of the heuristic evaluation method of our previous study. Exp. 1 compared the relative navigation efficiency of the original frame menu site and the revised pop-up toolbar site, and Exp. 2 compared the toolbar menu site and the revised frame site. As a result of Exp. 1, the revised pop-up toolbar site showed improved navigation efficiency compared to the original site, as indicated by the mean latency and the number of pathways to reach the target page. However, we found no performance difference between the frame site and toolbar site in Exp. 2.

기존의 인터넷 익스플로러는 높은 보급률의 이점을 지니고 있지만 인터넷을 이용하기 위한 기본지식의 필요성과 키보드, 마우스와 같은 장치를 이용한 입력방식은 장애인 및 고령층의 사용자들이 이용하기에는 불편하다. 이와 같은 문제점을 해결하고자 본 논문에서는 웹 서비스 기술을 이용하여 기존의 음성인식 시스템을 웹 서비스로 재구성하고 클라이언트가 음성인식 웹 서비스를 요청하고 음성명령이 가능하도록 인터넷 익스플로러에 음성명령이 가능한 Navigaotr를 Toolbar 형태의 프로그램을 구현하였다. 본 시스템은 클라이언트가 사용하는 음성 Navigator Toolbar와 웹 서비스를 통해서 음성 서비스를 제공하는 음성 서비스 프로바이더로 구성된다. 음성 Navigator Toolbar는 인터넷 환경에서 음성데이터를 바이너리 포맷형식인 DIME을 이용하여 음성 서비스 프로바이더로 전송하고 반환 결과를 가지고 URL Navigator를 통해 인터넷 페이지를 이동시킨다. 음성 서비스 프로바이더는 사용자가 전송한 음성데이터를 인식기를 통해 인식하고 결과를 가지고 정보 Database를 검색하여 실제 인터넷 주소를 사용자에게 반환한다.

대부분의 관제사들은 매일 다루고 있는 콘솔에 불편한 느끼는 일이 많다. 하지만 이러한 관제사들의 생각이 VTS 시스템 개발에 반영되지 못하고 있는 것도 사실이다. 현재 개발 중에 있는 u-VTS(차세대 한국형VTS)에 관제사들의 현장 경험을 접목시키는 것이 중요하다. 본 연구는 유저 인터페이스에 대해서 알아보고, 관제사의 상황자각 및 의사결정에 실질적인 도움을 줄 수 있는 방향으로 운영자 콘솔의 유저 인터페이스가 개선되도록 하는데 초점을 두었다.

Consumer-centric marketing business is surely one of the most successful emerging business but it poses a threat to personal privacy. Between the service provider and the user there are many contrary issues to each other. The enterprise asserts that to abuse the privacy data which is anonymous there is not a problem. The individual only will not be able to willingly submit the problem which is latent. Web traffic analysis technology itself doesn't create issues, but this technology when used on data of personal nature might cause concerns. The most criticized ethical issue involving web traffic analysis is the invasion of privacy. So we need to inspect how many and what kind of personal informations being used and if there is any illegal treatment of personal information. In this paper, we inspect the operation of consumer-centric marketing tools such as web log analysis solutions and data gathering services with web browser toolbar. Also we inspect Microsoft explorer-based toolbar application which records and analyzes personal web browsing pattern through reverse engineering technology. Finally, this identified and explored security and privacy requirement issues to develop more reliable solutions. This study is very important for the balanced development with personal privacy protection and web traffic analysis industry.

Icons are the main element of the graphic user interface (GUI). They can help users perform effectively on the computer, especially when the icons reflect user`s mental model. However, few studies in Korea represented Korean users` mental models in icon design. The purpose of this study, therefore, was to ascertain whether existing icons agreement with Korean twentieth mental model, and to deduce properties of Korean twentieth mental model. To do that, 10 icons from two commercially available toolbar-icons of word processing programs were compared with the newly developed icons, which were developed to represent Korean user`s mental modelthrough interviews, surveys, and mental model sketches. The results show that five new metaphors were found: a dog-eared part on the bottom right corner new for new document, a magnifying glass for search, a red pencil for spell-check, `＋` and `` signs in the magnifying glass for zoom, and a yellow post-it for paste. These new icons were preferred to the existing. Korean twentieth users preferred rather complex and dynamic icons than simple and static ones even though icon development guideline said simple icons are better.

As damages from phishing have been increased, many anti-phishing solutions and related researches have been studied. Anti-phishing solutions are often built in web-browsers or provided as security toolbars. Other types of solutions are also developed such as email-filtering and solutions strengthening server authentication via secret image sharing. At the same time, researchers have tried to see the reasons why phishing works and how effective anti-phishing solutions are. In this paper, we review relevant anti-phishing solutions, their techniques and other phishing-related researches. Based on these, we summarize recommended ways to improve anti-phishing solutions and suggest the future directions to study to protect users from phishing attacks.

In the field of oriental medicine, many researchers head for the aim of standardization. To achieve this aim, oriental medical researchers have been carried out experimental research, statistical research, clinical research, philological research, etc., and, have published their results to journals. But, the declaration of Roman name of herbal formula is not united each other, on several article. So, we should prepare database to search in domestic and overseas, and should consider compatibility of internationally used search system. Also, it is need to use appropriate roman letters in oriental medical terms for people can use easily. We inquired the type of roman letters in the name of formula of article that were carried oriental medical journal, to find out appropriate roman letters and to the demands of the times. There were many cases that Korean name of formula is not correspond to the declaration of Korea roman letters. Also, the declaration of roman letters for preparation like as tang(湯), san(散), hwan(丸) etc. are not standardized. To facilitate making database and forming search system, now we suggest that we can standardize the declaration of Korea roman letters by using of Hangul(한글) word processor's toolbar which has transformation of roman letters.
