According to ISO/IEC 9000, quality to satisfy users' requirements when using the product or service is defined as the characteristics of the synthesized concept. Secure web application coding information systems with the reliability and quality of service is one of the determining factor. Secure coding in order to achieve the quality based on the model is necessary. The reason is that the security is in quality properties in the range of non-functional requirements that necessitates. Secure coding for the design of quality systems based on the quality of the definition of quality attributes, quality requirements, quality attribute scenarios are defined, and must be set. To this end, referring to IEEE 1061 quality model for web application, quality model structure is developed. Secure web application architecture design is composed of coding quality of the model systems, web applications draw interest to stakeholders, decision drivers secure coding architecture, quality attributes, eliciting quality requirements of the security settings, creating web application architecture descriptions and security framework.

In order to reduce a product life cycle and to improve productivity, it is required to automate the design/analysis processes. In general, since the design/analysis processes need a lot of time and resources, the various engineering resources should be integrated and utilized effectively in the distributed environments. KIMM (Korea Institute of Machinery and Materials) constructed the SOA-based e-Engineering framework to automate the execution of the design/analysis processes and to integrate the engineering resources in the distributed environments. This paper presents the concepts and the structures of the e-Engineering framework. Also it classifies the exceptional cases that will be able to occur in the e-Engineering framework and suggests the recovery techniques from the exceptional cases with viewpoints of the engineering process and the task, respectively.

The social computing which is growing rapidly, has been scaling up the influencing power in every area and extending its activities into the political area. On the other hand, political participation trend of citizens gave rise to an innovative idea, so called 'Smart Citizens Party'. This requires the receptiveness and the openness of the party. So smart citizens party needs the smooth communication structure based on social computing as well as ICT(Information Communication Technology). That is, to embody the Smart Citizens Party, social computing framework for its is required. The purpose of this study is to suggest the social computing framework as the technical base of smart citizens party. To achieve this purpose, this paper will analyze the rise of the social web and ICT & innovation of public(and political) sector, study the concept and impacts of social computing and the concept and characteristics of Smart Citizens Party, and describe the framework, its elements and its service functions of social computing.

It has lately been recognized that the sharing and exchanging of the research results information is the critical factor to improve the research productivity. So many institutions are planning or developing the information systems which provide the research information services for researcher. But it has very difficulty in integrating the research resources information due to the dispersion and heterogeneity in data sources, and semantic and structural difference in describing data. We propose the semantic web based methodology and conceptual framework for raising the interoperability of metadata about research results information, which will support the integration of the distributed research data for information services in the end. Finally we proposed the conceptual architecture of research information service system which shows the main components, the functional requirements, and the principal and design direction at implementing the system.

Ontology를 이용한 대부분의 이미지 검색 시스템들은 중앙 집중적(Centralization)으로 구성되어 있어, 단일 이미지 제공자의 특정 지식기반의 이미지 검색을 제공한다. 이에 반해 메타데이터 기반의 분산 이미지 검색 시스템들은 이미지 제공자들의 자율성을 보장하기 용의하지만, 지식기반 이미지 검색을 제공하지 못한다. 본 논문은 위 시스템들의 단정들을 극복하기 위해 Web Services를 이용하여 다양한 이미지 제공자들의 자율성을 보장하면서, 지식기반 이미지 검색을 지원하는 프레임워크의 Architecture를 제안한다.

Connectivity is becoming more important keywords recently. For example, many devices are going to be connected to the internet. It is usually called as the IoT(internet of things). Many IoT devices can be evolved as a part of giant system of the world wide web. It is a great opportunity for us, because many new services can have emerged through this paradigm. In this paper, we propose a device virtualization framework for smart home service. The proposed framework connects the many home appliances devices and the internet using a dynamic protocol conversion. After our protocol conversion for device virtualization, our framework provides a RESTful API to access the resources of device through the internet. Therefore, the proposed framework can provide a variety of services, so it also can be developed into the ecosystem for smart home service. The current framework version only supports UPnP enabled devices of the home, but it can easily be extended to many other home middleware solutions. To verify the feasibility of the framework, we have implemented several service scenarios.

The performance of a web application is an essential issue to provide high quality of the services in interactive web environments. On a sudden increase in traffic in a very short span of time, the servers became CPU starved and would become unresponsive. This would lead to a bad experience for the clients of web service. This paper deals with the effects of two configurable software settings of J2EE application servers: the maximum size of the thread pool and the maximum size of database connection pool. In order to figure out the optimum configuration value, this paper builds experimental evaluation method for web performance analysis. Finally, a case study related with the proper experimental method is presented with performance result.

Recently, ASP business models based on Web services are attracting considerable attention and regarded as the next generation of the ASP business models. It is, however, undesirable for ASP users to adopt them simply because the Web services are the new trend in the IT world. Instead, an in-depth comparison of the benefits against the costs between the Web services based ASP business models and the traditional models are required. Furthermore, it is desirable that this comparative analysis should be applied from the ASP users' viewpoints rather than those of the government or ASP providers. So, we have applied a comparative ROI (Return on Investment) analysis from the ASP users' perspective and shown that the Web services based ASP business models (382%) are superior to the traditional models (280%) in terms of ROI. We have also employed Balanced Scorecard (BSC) framework to keep the balance between tangible and intangible benefits considering the characteristics of IT value measurement.

Previous process for issuing and messaging tax-invoice needs too much cost and has risky problems such as loss or forgery. A rule for an electronic tax-invoice can make up for the weak points. In the tax-invoice system based on web environment, the messaging electronic tax-invoices is more important than the issuing it. Therefore, a messaging system should be developed for submitting tax-invoice efficiently and safely. In this paper, we implement an electronic tax-invoice messaging system based on Hermes 2 which is an open source framework for electronic document messaging.
