The computing systems of today expanded business trade and distributed business process Internet. More and more systems are developed from components with exactly reusability, independency, and portability. Component based development is focused on advanced concepts rater than passive manipulation or source code in class library. The primary component construction in CBD. However, lead to an additional cost for reconstructing the new component with CBD model. It also difficult to serve component information with rapidly and exactly, which normalization model are not established, frequency user logging in Web caused overload. A lot of difficult issues and aspects of Component Based Development have to be investigated to develop good component-based products. There is no established normalization model which will guarantee a proper treatment of components. This paper elaborates on some of those aspects of web application to adapt user requirement with exactly and rapidly. Distributed components in this paper are used in the most tiny size on network and suggest the network-addressable interface based on business domain. We also discuss the internal and external specifications for grasping component internal and external relations of user requirements to be analyzed. The specifications are stored on Servlets after dividing the information between session and entity as an EJB (Enterprise JavaBeans) that are reusable unit size in business domain. The reusable units are used in business component through query to get business component. As a major contribution, we propose a systems model for registration, auto-arrange, search, test, and download component, which covers component reusability and component customization.

It has not been studied about modeling methods for SVG documents to represent animation in the web that has been recently increased in interest. In this paper, I propose component modeling for SVG documents by CBD methodology. First, I propose conceptual modeling by UML class diagrams for converting SVG document into component diagram. And then, I propose rules to convert the UML class diagram into component diagram. Thus, main contribution of this paper is that it can generate a component diagram for a SVG document using Component-Based Development methodology.

WebView is a vital component in smartphone platforms like Android, Windows and iOS that enables smartphone applications (apps) to embed a simple yet powerful web browser inside them. WebView not only provides the same functionalities as web browser, it, more importantly, enables a rich interaction between apps and webpages loaded inside the WebView. However, the design and the features of WebView lays path to tamper the sandbox protection mechanism implemented by browsers. As a consequence, malicious attacks can be launched either against the apps or by the apps through the exploitation of WebView APIs. This paper presents a critical attack called Supplementary Event-Listener Injection (SEI) attack which adds auxiliary event listeners, for executing malicious activities, on the HTML elements in the webpage loaded by the WebView via JavaScript Injection. This paper also proposes an automated static analysis system for analyzing WebView embedded apps to classify the kind of vulnerability possessed by them and a solution for the mitigation of the attack.

Prefabricated partially-encased composite (PEC) structural component is widely used in construction industry due to its superior structural performance and easy assembly characteristic. However, the solid web in traditional PEC components tends to split concrete into two halves, thus potentially reduces structural integrity and requires double concrete pouring. To overcome the above disadvantages, a new PEC beam with open-web π-shaped steel is proposed in this paper. Four open-web PEC beams with varying sectional height, flange thickness and web void rate were constructed and tested under flexural loads. During experimental tests, all beams exhibited typical flexural failure modes with strong moment capacities and excellent ductility. Owing to the unique construction form of web opening, steel-concrete bonding properties were enhanced and very small relative steel-concrete slips were observed. Experimental results also showed that the flexural capacity of such PEC beams increased with the increase of the sectional height and flange thickness, while was not affected by the web void rate. At last, a flexural capacity formula of the open-web PEC beam was proposed based on the whole section plastic rule. The formula results agreed well with experimental results.

This paper proposes 2 problems of Internet Marketing. Firstly, nowadays many people are aware of Web Service and the services that are available in cyberspace. However they are not fully aware of the concepts and range of Web Services. Secondly, most of the research of Internet Marketing focuses on the service quality of cyber shopping using SERVQUAL in relationship to service quality of shopping malls. Therefore they have a lot of limitations because they do not understand all the media characteristics of Internet. Basically the Internet has service parts and also has characteristics of new advertising. But many research papers do not consider these respects. The purpose of this paper is to study of the effects of Web Service Quality on Internet Commerce Transactions. To accomplish the purpose of this paper effectively, theoretical background of web services was reviewed briefly. We defined Web Services and categorized them. We found that the components of Web Service Quality are Information Providing Service Quality and Advertising Service Quality. Factor analysis is conducted according to the dimensions of each component. We conducted Path analysis how these components affect buyers'attitude and buyers'attitude affect revisit intentions and buyer intentions. The results show that strategies of cycler brand construction are better than strategies of selling to web surfers. The strategies of cyber brand construction are related to buying in that customers increase their visits to the entrepreneur's Web site and this increases the loyalty to that site therefore this is related to buying habits.

This study examined the effects of Web ad components on customer attitude and purchasing decisions in 300 individuals who visited family restaurant Websites. The results are summarized as follows: First, Web ad components such as content, design, and interactivity had effects on the cognitive attitudes of the customers. And design, accessibility, and Web functionality had significant effects on the customers' emotional attitudes. In addition, content, navigation, and Web functionality had significant effects on the customers' behavioral attitudes. Lastly, the cognitive, emotional, and behavioral attitudes of the customers had significant effects on their purchases. From these results, design elements such as content, color, and menus, along with user interactivity for information are considered helpful components of a food service Web ad for customer cognition of the restaurant's information. In addition, aspects of Web functionality such as the food service's Web ad set-up, or the protection of personal information, the color design and menu, as well as accessibility for easy use, are all helpful in terms of gaining a customer attitude that is friendly and preferential towards a restaurant's menu items.

Component-based software reuse has been generally regarded as a promising approach to improving software productivity and quality within software development. However, progress in component-based software reuse has been slower than expected. Much of the software reuse literature points to the lack of software components that can maximize users' benefits as the most important source of the slow progress. Considering that the underlying processes behind component-based software reuse are strikingly similar to commercial software marketing, this paper attempts to identify the aspects of software components that consumers value and to establish relationships between the identified aspects and consumer behavior in the software component market. More specifically, this paper focuses on the perceived subjective features of software components. This study was conducted in a web-based artificial market environment called "SofTrade."

In this paper we describe interoperability maturity measurement, due to highlight a momentous issue on interoperability between heterogeneous distributed component based systems. it also suggests one of various ways for supporting interoperability between each other different component based systems, that is, using web services based mechanism and also revises 'LISI (Level of information systems interoperability)' model to measure interoperability maturity. We also develop the interoperability questionnaire based on the interoperability factors considered at each phase of component based development process, which is possible to measure interoperability maturity between heterogeneous distributed component systems. Based on revised interoperability maturity model and questionnaire we measure each interoperability maturity on examples of two different implementations, that is, web services and distributed object based mechanism. As a result, we suggest an enhanced interoperability way based on analysing problems af these measured results.

The main topic of this paper is how to structure information so that the view of the web, both within and across web pages, is dynamically customizable. We present an architecture that integrates Object-Oriented Databases with the World Wide Web to organize such dynamic structures. Different non, or the same user at different times, could have different views of the web. We discuss several architectural variants and implementation issues. Our chosen architecture provides high flexibility for a wide variety of applications, ranging from software development environments to the IO-web system.
