As web 2.0 becomes one of the important architecture styles, more web applications adopt single page structure instead of multiple web pages and navigations between pages. A single page web application client, called a mashup client in this paper, interfaces more than one services and allows users to navigate in the page. A mashup client page includes complicated functions and has to handle various styles of services and user requirements, and therefore is usually developed manually. In this paper, we propose a model driven code generation approach for in-page navigations. We propose a page model and view navigation design approach, applying REST service architecture patterns. Then, we consider type conditions for each view to have service calls or navigation controls. Also, we developed an XForms page code generation system to demonstrate the efficiency of the proposed method. The developed system generates mashup client pages including navigation controls between services and views. This system can generate ready to use codes from service specifications, so this can help to reduce the development overhead. Moreover, our approach is based on formal model and navigation patterns so the generated result code is simple and easy to understand, and includes only the necessary controls. Therefore, the proposed approach can be more effective for the case of a large number of services.

As concerns about users' privacy infringement on Online Behavioral Advertising(OBA) increase, regulators are taking measures such as drawing up guidelines for OBAs, and websites provide OBA guidance in compliance with such guidelines. As a result of reviewing the status of providing OBA guidance on websites, access to OBA guidance pages was rather complicated. In order to analyze the issue from the UI/UX perspective, following the "Guidelines for Privacy in Online Behavioral Advertising" applied to all types of OBA transmitted on websites, this study aims to structuralize a navigation of page movement from two starting points, 1) Main Page, 2) The page where OBA is delivered, to OBA guidance pages. Also, with understanding the problems found in the access and navigation of OBA guidance pages by analyzing features found during the page navigation, such as hyperlinks containing keywords, and movement pages.

Convenience and promptness of the internet have been not only making the electronic commerce grow rapidly in case of website, analyzing a navigation pattern of the users has been also making personalization and customization techniques develop rapidly for providing service accordant to individual interestingness. Web personalization and customization skill has been utilizing various methods, such as web log mining to use web log data and web mining to use the transaction of users etc, especially e-CRM analyzing a navigation pattern of the users. In this paper, We measure exact duration time of the users in web page and web site, compute weight about duration time each page, and propose a way to comprehend e-loyalty through the computed weight.

People are experiencing severe navigation problems in mobile site Relatively limited research, however, has been conducted on mobile site navigation compared to web site navigation. This research aims to identify efficient mobile site navigation aids for timely preferred contents. It proposed timely menu system based on statistic data, and evaluates its efficiency through commercial beta test. We conducted a beta test in the fourth quarter of the year 2007. The total number of user is 12,000. The average number of PV (page view) by the experimental group was increased to 10% more than control group. Our results indicate that timely menu system helps people navigate mobile menu system more effectively.

Recently the mobile DBMS (Database Management System) is popular to store and manage large data in a mobile device. Especially, the research and development about mobile storage structure and querying method for navigation map data in a mobile device have been performed. The performance of the mobile DBMS in which random data accesses are most queries if the NAND flash memory is used as storage media of the DBMS is degraded. The reason is that the performance of flash memory is good in writing sequentially but bad in writing randomly as the features of the NAND flash memory. So, new storage structure and querying policies of the mobile DBMS are needed in the mobile DBMS in which a flash memory is used as storage media. In this paper, we have studied the policy of the database page management to enhance the performance of the frequent random update and applied this policy to the navigation-specialized mobile DBMS which supports incremental map update. And also we have evaluated the performance of this policy by experiments.

Main content extraction of web pages is widely used in search engines, web content aggregation and mobile Internet browsing. However, a mass of irrelevant information such as advertisement, irrelevant navigation and trash information is included in web pages. Such irrelevant information reduces the efficiency of web content processing in content-based applications. The purpose of this paper is to propose an automatic main content extraction method of web pages. In this method, we use two indicators to describe characteristics of web pages: text density and hyperlink density. According to continuous distribution of similar content on a page, we use an estimation algorithm to judge if a node is a content node or a noisy node based on characteristics of the node and neighboring nodes. This algorithm enables us to filter advertisement nodes and irrelevant navigation. Experimental results on 10 news websites revealed that our algorithm could achieve a 96.34% average acceptable rate.

In this paper, we developed the circuit and part information maintenance system based on JSP (Java Server Page) web server using web browser. Designers can easily search part information and register the new components or parts, and this system is linked to the EDA (Electronic Design Automation) system to be applicable to the circuit and part schematics in real time. Therefore, EDA system part library managed by individual designers are integrated into the web-based maintenance system.

The existing web page was downloaded and provided to the user every time the user requested the page. Therefore, if the same page is repeatedly requested by the user, only the download for the same resource is repeated. This is a factor that causes unnecessary consumption of data. We focus on reducing data consumption caused by unnecessary requests between users and servers, and improving content delivery speed. Therefore, in this paper, we propose a caching system and an algorithm that can reduce the data consumption while maintaining the latest cache by comparing the hash value using the hash function that can detect the change of the file requested by the user.

Client based web mashups have become one of the most important architecture in web application development. Although there are well known methods to generate presentation view codes for web services, navigations between views and service requests are still developed manually in most web mashups. In this paper, we propose the concept of deterministic data binding from output data to input parameters of another method. Using binding relations, we can model navigation menus for service method requests. For a given set of data mappings between services, we investigate context dependent binding conditions and discuss the generation of views and navigation menus. The proposed approach provides UI for users to navigate services of client mashup page using simple and convenient interface even when the number of services and the size of the mashup page grows. In order to show the usability of the proposed approach, we present a historic tourism service.

Web 기반 시스템 구축시 저렴한 구축비용, 표준화된 문서환경, 클라이언트를 통일하지 않고도 어플리케이션의 구현이 가능한 장점 때문에 인터넷 프로토콜인 TCP/IP와 HTTP를 기반으로 시스템을 구축하려는 기업과 조직이 늘고 있다. 본 논문에서는 web 환경에서 시스템 구축시 적용할 수 잇는 web 기반 시스템 분석/설계 모형을 제안한다. 기존의 web 어플리케이션 개발 방법들이 데이터 분석에 기초를 둔 것과는 달리, 기업과 조직이 가지는 기능을 중심으로 web 어플리케이션을 분석하고, 파악된 기능에서 pageflow를 설계하여 사용자의 요구사항과 조직의 처리가 반영된 page와 네비게이션 경로(navigation path)를 설계할 수 있는 모형을 제시한다.
