  • In order to connect web services, clients generally should use heavy frameworks such as .Net framework and Java run-time environment, which require high performance hardware resources like a personal computer. Therefore, it is impossible for sensor nodes to handle web services due to their limited resources. In this paper, a client agent framework is proposed for dynamically connecting web services in the client node with limited resources. A client agent, which is managed by the framework in other server, has full capability for connecting web services, while a real client has a simple connection module with the client agent. In this framework, a client agent is dynamically generated using the WSDL in the web service server. By using the framework, sensor nodes or mobile devices can enhance their functionalities and services by accessing web services with minimum resources.

  • With greater utilization of web application and growth of its market, the function of such application is being expanded With today's increasing demand for high quality software, we see a sharp rise in the interest for web application test. The current trend is that web applications are being developed based on a framework of developmental environment. Hence, as the scope of that framework expands, each module of the entire web application is being configured by the combination of heterogeneous files. The distinctive characteristics of a web application are based on the fact that the framework that is provided in partially completed form controls the structure of all objects of development. The present study defines the web business logic as a minimal unit which has meaning as a unit of application for the web application. In this paper, we define web business logic as a least meaningful execution unit of web applications, propose how to generate automatically the BizUnit test code for it, and analyze the effectiveness of testing of the web application via the BizUnit test codes.

  • Researchers require repetitive works such as data format analysis, reformatting and map reprojection in order to use geospatial data. To solve above problems, they are building web-based simulation systems with web developers. But the web-based systems are not efficiently developed because there is not the appropriate simulation framework for a web-based system using geospatial data. In this study, the geospatial simulation framework that can be effectively applied to the web-based system was designed and proposed. Also, the framework was composed of 7 modules; web mapping service, GIS mapping, statistics, model, processing,graphics, and geospatial datasets. In order to evaluate the effectiveness of the framework, a case study of urban growth has been verified. Experts who are not specialized in geospatial information disciplines expect to build easily a web-based system using geospatial data.

  • In a web 2.0 environment, as a wide range of web services are being utilized, it requires quick and convenient way to develop web applications. For this purpose, the framework has been recently introduced and has been applied to web applications. However, software quality application model has not been presented for the web application using framework. In this paper, we develop web application, online library system using a number of frameworks. The system allows users to freely share book information. In order to evaluate the system, we present new software quality evaluation model for web applications using framework. The five quality attributes, functionality, usability, efficiency, maintainability, stability are defined based on the international standard for software quality evaluation, ISO/IEC 9126-2. We also propose the evaluation metrics for the web application using framework and perform quantitative evalzuation for the online library system.

  • eLearning can be defined as an approach to teaching and teaming that utilises Internet technologies to communicate and collaborate in an educational context. This includes technology that supplements traditional classroom training with web-based components and learning environments where the educational process is experienced online. The use of hypertext as an educational tool has a very rich history. The advent of the internet and one of its major application, the world wide web (WWW), has given a tremendous boost to the theory and practice of hypermedia systems for educational purposes. However, the web suffers from an inability to satisfy the heterogeneous needs of a large number of users. For example, web-based courses present the same static teaming material to students with widely differing knowledge of the subject. Adaptive hypermedia techniques can be used to improve the adaptability of eLearning. In this paper we report an approach to the design a unified implementation framework suitable for web-based eLearning that accommodates the three main dimensions of hypermedia adaptation: content, navigation, and presentation. The framework externalises the adaptation strategies using XML notation. The separation of the adaptation strategies from the source code of the eLearning software enables a system using the framework to quickly implement a variety of adaptation strategies. This work is a part of our more general ongoing work on the design of a framework for adaptive content delivery. parts of the framework discussed in this paper have been imulemented in a commercial eLearning engine.

  • Recently, as various devices including the smart phone, tablet and smart TV increase rapidly, it have been trouble to develop services separately, which are the same as in each device. When it comes to manufacture these kinds of web applications, what is worse, it takes too much time, cost ineffective and hard to maintain as well. In order to solve the non-unity of these flat forms, some researches for the responsive web design according as the hybrid framework are being progressed. In this paper, we analyzed the technologies and trends of the hybrid framework, and also implemented the responsive web contents which is based on hybrid framework.

  • Many researchers have developed frameworks that are capable of handling context information and can be adapted and used by any Web service. However, no research involving the systematic analysis of existing frameworks has yet been conducted. This paper examines the Context Framework, an example of existing frameworks, using a Petri net, and analyzes its advantages and disadvantages. Then, a Petri net model - with its disadvantages removed - is introduced, and a new framework is presented on the basis of that model. The proposed PAWS (Privacy Aware Web Services) framework has a expendability for context management and communicates flexible context information for every session. The proposed framework can solve overhead problems of context in SOAP messages. It also protects user privacy according to user preferences.

  • Because the complexity in the development phase of geographic information system, its hard to change its operation or user interface after the development. So we should develop most part of the applied GIS even though previous GIS is almost exist. In other words, reusing the previous system is not easy. Therefore, its required to research reusable GIS for easy construction of applied GIS. This thesis describes design and implementation of web GIS framework which makes applied web GIS development more easy. Framework is software library composed of reusable units such like classes and objects. Proposed web GIS framework Provides basic web GIS functionalities and execution design to web GIS developers. They could extend the framework to build applied web GIS with applied operation and user interface. The development of applied web GIS could be archived by various tools used for general web application development.
