To enhance web site's usability, it has been suggested that the depth of tree structured menus should be minimized. In this research, experimental results are reported to quantitatively compare the methods currently used for reducing the depth of menus in web sites. 25 popular web sites were selected and their menu types were categorized into four types: top menu, drop-down menu, boolean menu, and table of contents. The four types of menu were then sub-categorized into 15 different types according to their sub-menu type, existence of menu colors, and the event occurring after mouse activation. Performance tests and subjective evaluation were carried out. The results showed that there were no significant differences in terms of response time among the 15 menu types, while table of contents and drop-down in which the first and second level of menus were visible induced the least number of errors. In the subjective test, the top-menu structure with colors and presentation of its sub-menu without clicking mouse were preferred.

Since the World-Wide Web (WWW) has become a major channel for information delivery, information overload also has become a serious problem to the Internet users. Therefore, effective information searching is critical to the success of Internet services. We present an integrated search engine for searching relevant web pages on the WWW in a certain Internet domain. It supports a local search on the web sites. The spider obtains all of the web pages from the web sites through web links. It operates autonomously without any human supervision. We developed state transition diagram to control navigation and analyze link structure of each web site. We have implemented an integrated local search engine and it shows that a higher satisfaction is obtained. From the user evaluation, we also find that higher precision is obtained.

온라인 미디어의 발전으로 인터넷 신문 웹사이트의 유형과 범위도 확대되고 그에 따른 정확한 평가가 필요해지고 있다. 특히 웹사이트의 유형에 따라 평가요인의 상대적 중요도가 다르기 때문에, 그에 따라 요소들의 중요도를 정확히 추출하는 것이 중요하다. 그러나 인터넷 신문 웹사이트 평가요소를 합리적으로 산출하는 방법에 관한 연구는 아직 미흡하다. 본 논문에서는 인터넷 신문 웹사이트의 특화된 요인을 산출하고 분석하기 위하여 HP 기법을 적용하였다. 특히, 인터넷 신문 평가를 위해 처음으로 평가 요소의 가중치를 활용하였다. 이러한 신출물에 대한 분석 결과는 새로운 인터넷 미디어 서비스 개발에 활용될 수 있다.

인터넷과 웹의 급속한 성장과 함께 기존의 시스템들이 웹을 기반으로 통합되면서 비즈니스 환경을 급속하게 변화시키고 있다. 그러나 웹은 다양한 기술의 접목으로 개발된다는 점과 본래의 복잡성으로 인해 개발과 관리에 있어 어려움이 더욱 증대되고 급변하는 비즈니스 환경과 사용자들의 요구사항에 순응하기 위해서는 지속적인 진화가 요구된다. 이와 같은 웹의 본질적인 복잡함과 짧은 생명주기는 웹사이트의 성공적인 개발과 유지보수를 위해서 많은 비용과 노력의 소요를 유발한다. 본 논문에서는 웹사이트의 개발과 유지보수에 대한 비용을 절감하고 효율적인 구조 관리와 평가를 지원하기 위해 개발된 시스템을 제안한다.

인터넷과 웹의 빠른 발전과 더불어 비즈니스프로세스, 지식 경영, 마케팅, 전자 상거래 등 현대의 다양한 IT 시스템들이 웹으로 통합되면서 비즈니스 환경을 급격하게 변화시키고 있다. 웹의 본질적인 복잡함과 짧은 생명주기는 웹 사이트의 성공적인 개발과 유지보수를 위해서 많은 비용과 노력의 소요를 유발한다. 이러한 상황에서 웹 사이트의 효율적인 관리와 평가 방법 및 시스템적인 지원은 웹 사이트의 개발과 유지보수에 있어 핵심적인 요소라 할 수 있다. 본 논문에서는 웹 사이트의 개발과 유지보수에 대한 비용을 절감하고 효율적인 구조 관리와 평가를 지원하기 위해 개발된 시스템과 7단계의 효율적인 관리와 평가 방법을 제안한다.

This study proposes a web presence readiness model based on pre-payment service functions and a post-payment service function both of which embrace the major concerns of customers in the online purchasing context. Based on the concept of customer utility from the product itself and instrumental utility, the research model suggests four antecedents including, Perceived Economic Benefits, Product Search Support Quality, e-Shopping Method Diversity, and Post-Payment Support Quality. We empirically examined a proposed research model using data collected from online rating company websites. Among the four antecedents, post payment support quality is found to be the most influential determinant of customer evaluation on e-commerce websites. Based on the empirical results, the current study proposes an alternate model of web presence readiness. The findings of this study may provide an insight to field practitioners designing commercial websites. The implications and future research directions are further discussed.

The concept of an "intelligent building" received significant attention from academic, industry and standard development organizations when technically termed a building management system (BMS). Wireless sensor networks (WSNs) and their recent development enhanced monitoring and control applications for the building's areas. This paper surveys and analyzes advantages of the main current and emerging approaches that may be fit for BMS. Specifically, we discuss challenges including interoperability, integration, overhead, and bandwidth limitation of WSNs in BMS. Based on analyses, we highlight the advantages of an IP-based and RESTful architecture approach as the most suitable solution for BMS using WSNs (BMS-WSN). The paper also describes our future direction and design for BMS-WSN based on these advantages. The purpose is to enable interaction of users with BMS-WSN in the same way as with any website while ensuring energy efficiency. A test-bed implementation and evaluation of a BMS application is also introduced in this paper to demonstrate the feasibility and benefits of IP-based and RESTful architecture for BMS.

For web application vulnerability diagnosis, from the development stage to the operation stage, it is possible to stably operate the web only when there is a policy that is commonly applied to each task through diagnosis of vulnerabilities, removal of vulnerabilities, and rapid recovery from web page damage. KISA presents 28 evaluation items for technical vulnerability analysis of major information and communication infrastructure. In this paper, we diagnose the vulnerabilities in the automobile goods shopping mall website and suggest security measures according to the vulnerabilities. As a result of diagnosing 28 items, major vulnerabilities were found in three items: cross-site scripting, cross-site request tampering, and insufficient session expiration. Cookie values were exposed on the bulletin board, and personal information was exposed in the parameter values related to passwords when personal information was edited. Also, since the session end time is not set, it was confirmed that session reuse is always possible. By suggesting security measures according to these vulnerabilities, the discovered security threats were eliminated, and it was possible to prevent breaches in web applications and secure the stability of web services.
