In this paper, we describe a design and implementation of Web Services that convert WML(Wireless Markup Language) Page into .NET Mobile Web Page. The Web Services has an advantage that is available everybody without restriction oi platform and programming language. In this paper, we implement the Web Services Provider providing of converting system and the Web Services Consumer using this system. The Clients can get results of .NET Mobile Web Page without difficulty through Web Server because of implementation of Web Services Consumer using Web Services. Also the clients can develop new application using Web Services without respect of its implement process.

오늘날 인터넷 및 정보통신의 발달로 인하여 전자상거래가 활성화되고 있으며 기업들은 웹에서의 전자상거래를 위하여 e-카탈로그를 제작하여 사용하고 있다. e-카탈로그는 종이 카탈로그에 비하여 제작 비용이 적게 들고 발송 비용이 들지 않으며, 카탈로그를 필요로 하는 업체나 개인이 신속하게 카탈로그를 받아볼 수 있는 등 여러 가지 장점을 가지고 있다. e-카탈로기는 현재 웹 표준으로 자리잡아가고 있는 XML로 제작되고 있는 추세이다. 또한 최근에는 유선 인터넷 뿐만 아니라 무선 인터넷에 대한 요구 및 수요가 증가하면서 유선 인터넷에서 사용하던 문서를 무선 인터넷에서 사용하고자 하는 요구가 늘고 있다. 이에 본 논문에서는 .NET에 기반한 XML-WML 문서 변환 시스템을 제안함으로써 플랫폼이나 OS의 영향을 받지 않고 사용할 수 있으며, 다른 응용프로그램과의 유연성 있는 통합도 가능하도록 설계되었다.

In this paper, we make a performance analysis of two kinds of platforms, JAVA and .NET, about SOAP(Simple Object Access Protocol). SOAP is able to use various transport layer protocol but in this paper we suggested methods of performance analysis with using HTTP, TCP, UDP and then we made an performance analysis on the basis of suggested methods. The results of performance analysis may be deduced differently by a system environment and loaded degree of network. Therefore, for precise performance analysis, we made same environment and proceeded.

As computer technology continues to evolve, the Computational Sciences utilized in Physics, Chemistry, Materials Science, and Life Sciences have been attracting more attention. In Korea, to compensate for the drawbacks in Computational Science, students and researchers have been using the EDISON platform. The EDISON platform provides a web portal service for education and research and an environment for addressing complex issues involving five fields, e.g., Computational Fluid Dynamics (CFD), Nanophysics, Computational Chemistry, Structural Dynamics, and Computational Design. As the platform and user scale increase beyond service provision, the need for efficient operation of its currently running data management system is on the rise. In this study, we resolve the data synchronization issues between the existing EDISON platform and web portal. As the EDISON platform is integrated with the web portal, a file management service is implemented to integrate the management of user data and files, which ultimately improves the overall efficiency of file management.

Mobile is expanding beyond just a content consumption tool to an exclusive platform role. Mobile content refers to the services of companies using mobile devices. The advantage is that it can analyze the user's behavior in real-time, increasing satisfaction according to preference. On the other hand, the disadvantage is that minors can easily make paid payments due to a convenient online payment environment. Be careful not to be exposed to provocative media without using a content unauthorized theft platform. In addition, it is necessary to find ways to increase the net function of the mobile content platform and reduce the dysfunction.

In this paper, we design and implement a mobile game based on windows phone platform. Visual Studio and the Windows Mobile software development kit(SDK) and developer tool kits (DTK) make it possible to create software for the Windows Mobile platform in Visual C#. Also The XNA Framework is the set of .NET libraries that developers will code against to build games. XNA Framework support PC and XBOX and a ZUNE HD multiplex platform environment and 2D and 3D games provides the necessary functions to a development. XNA Framework is to make it easier to develop games because the codes which are succeeded creates with automatic, implements a game development relation resource and the game logic. The key idea of our game is that we use shooting and ranking system to raise fun.

The future battlefield environment has changed platform centric warfare into a network centric warfare. The NCO is a operational concept to improve combat power through information sharing, shared situational awareness, decision making and synchronized action based on powerful network grid. In addition, these operational environment is composed of physical, information, cognitive and social domains. The platform environment system is associated with the OSI 7 layer. However, OSI 7 layer is limited to express NCW environment including cognitive and social domains. Therefore, we requires a new model for expressing cognitive and social domains. After we developed a new model, this model applied to the NCW architecture taxonomy.

In the realm of domestic online fashion platform industry the manual registration of product information by individual business owners leads to inconvenience and reliability issues, especially when dealing with simultaneous registrations of numerous product groups. Moreover, bias is significantly heightened due to the low quality of product images and an imbalance in data quantity. Therefore, this study proposes a ResNet50 model aimed at minimizing data bias through oversampling techniques and conducting multiple classifications for 13 fashion categories. Transfer learning is employed to optimize resource utilization and reduce prolonged learning times. The results indicate improved discrimination of up to 33.4% for data augmentation in classes with insufficient data compared to the basic convolution neural network (CNN) model. The reliability of all outcomes is underscored by precision and affirmed by the recall curve. This study is suggested to advance the development of the domestic online fashion platform industry to a higher echelon.

The industrial ecosystem around the Internet services has been evolving since the Internet was first introduced. The Net Neutrality issue best represents the process of the evolution and presents an inevitable challenge that the industry should overcome. This paper deals with this structural change with the Two-Sided Market framework and provides a System Dynamics(SD) model to evaluate the economic implications of the net neutrality policy. In particular, our approach analyzes the policy impacts when two competing platforms (network providers) play a role of the platform in a typical two-sided market, which connects Content Providers(CPs) with users. Previous studies show that the indirect network externality between these two markets makes the entire system tip to one platform. When the multi-homing in the CP market is allowed as in our model, however, their argument may lose its validity. To examine the system behavior, conducted here is SD simulations of our model. The simulation results show that co-existence of the competing platforms persists with the network effects over a certain threshold. The net neutrality policy seems to lower the threshold based on our experimental outcomes.

Context-awareness is one of the key features of ubiquitous paradigm. A methodology that is specifying the relationships between the contexts and services needs to be developed to intelligently and sensitively deal with dynamic environment. The existing models on context-aware modeling are difficult to verify the correctness of models with respect to timeliness. In this paper we propose an approach which includes timing constraint in the relations of the context model, and verify its effectiveness using colored Petri-Net. Moreover, a context-modeling toolkit including context-awareness engine and simulator is developed to support agent-based context-aware service. The effectiveness of the proposed methodology is demonstrated using an example of Usilvercare.
