Along with the rapid development of IT technology and business services, the effort to provide new services to the customers has been increasing, and also the improvement and enhancement of legacy systems are continuously occurring for rapid service delivery. In this situation, the quality assurance of the source code for the legacy system became a key technical elements that can quickly respond to the service needs. Refactoring is an engineering technique to ensure the quality for the legacy code, and essential for the improvement and extension of the legacy system in order to provide value-added services. This paper proposes some features of refactoring techniques through surveying and analyzing the existing refactoring techniques and tools to enhance source code quality. When service developers want to refactor the source code of the legacy system to enhance code quality, our proposed features may provide with the guidance on what to use any technique and tool in their work. This can improve the source code quality with correct refactoring and without trial and error, and will also enable rapid response to new services.

CUPPS is the latest international standard passenger processing system which is operated with airlines' check-in system, DCS (Departure Control System) in order to provide check-in and boarding services to passengers. The CUPPS standard has been revised in August 2009 leading by IATA (International Air Transport Association) who recommends replacing old legacy common use system with CUPPS to airports and airlines around the world. IATA is expecting to reduce the installation and maintenance cost of CUPPS by standardizing various legacy common use systems and device controls. Airlines are also expecting to take advantage of the system to reduce the application development cost as developing only one standard CUPPS application instead of developing multiple applications for nonstandard legacy systems. This research which focuses on development completed AIRCUS, R&D project of ministry of land, transport and maritime affairs accomplished by IIA, will present the result of pilot trial and the effective approach methods to increase the possibility of expanding overseas business by comparing old legacy system with CUPPS to prove the dominance of CUPPS over the legacy systems as well as doing foreign case studies.

Digital virtual manufacturing is a technology that aims for the rapid development of products and the verification of production-process in ways that are more efficient by integrating digital models within the entire manufacturing process. These digital models utilize various information technologies, such as 3D CAD and simulations. Mixed reality, which represents graphical objects for only needed parts against real scene, can bring a more enriched sense of reality to an existing virtual manufacturing system that is in a pure virtual environment, and it can reduce the time and money needed for modeling the environment. This paper suggests a method for planning virtual factory layouts based on mixed reality using legacy datathat are already constructed in the real field. To do this, we developed the method to acquire simulation data from legacy data and process this acquired data for visualization based on mixed reality. And then we construct display system based on mixed reality, which can simulate virtual factory layout with processed data. Developed system can reduce errors related with factory layout by verifying the location and application of equipments in advance before arrangement of real ones at the practical job site.

Due to not only proven stability and reliability but a significant investment and years of accumulated -experience and knowledge, legacy systems have supported the core business applications of a number of organizations over many years. While the emergence of Web-based e-business environments requires externalizing core business processes to the Web. This is a competitive advantage in the new economy. Consequently, organizations now need to mine the business value buried in the legacy systems for reuse in new e-business applications. In this paper we suggest a systematic approach to mining components that perform specific business services and that consist of the legacy system's assets to be leveraged on the modem platform. The proposed activities are divided into several tasks. First, use cases that realize the business processes are captured. Secondly, a design model is constructed for each identified use case in order to integrate the use cases with the similar functionalities. Thirdly, we identify component candidates from the design model and then adjust the component candidates by considering common elements among the candidate components. And also business components are divided into three more fine-grained components to deploy them onto J2EE/EJB environments. finally, we define the interfaces of components which provide functionalities of the components as operations.

This letter introduces a stereoscopic video broadcasting system that provides 3D visual service and has full backward compatibility with legacy digital television (DTV) service in the same channel capacity. The proposed stereoscopic video broadcasting system in this letter is composed of both a hybrid codec and a multiplexer with a newly defined stereoscopic-related signaling method. In conclusion, the proposed method can be effectively applied for 3D broadcasting services without major changes in legacy broadcasting platforms.

In this paper, we consider the interworking methods for Internet layer 3 protocols. The legacy protocol for Internet is IPv4(IP version 4). The ability of IPv4 is not enough for modern real time multimedia communication services. So IPv6(IP version 6) protocol was suggested to resolve the problems of IPv4. 6Bones(IPv6 Backbones) have also constructed from 1996 in many countries. The 6Bones should be interoperatable to the legacy internet. To support all data services including voice and video, IP protocol should be enhanced because the characteristics of modern network services are requiring QoS(Quality of Service) functions, plug and play, security, mobility and so on. So a new IP protocol, IPv6, has been developing to meet the requirements. In this paper, some migration methods for internets are described. We first describe the protocol compatibility problems and suggest some solutions and scenario to solve the problems.

This paper examined seemingly well-working compromises in identity construction, questioning whether the compromises could function only nominally in practice. The literature has paid attention to the conflicts which end up functionally sense-making, through either unilaterally enforced or mutually assimilated compromises. In contrast, this paper's analysis of Super Tuscan wines under the Italian government's quality regulation illustrated that the compromises between wineries and classification systems do not work well and make the classification systems meaningless in the end. This study thus argued that compromises in identity construction do not always result in functionally sense-making outcomes: they could be only nominal. This study suggested that idiosyncratic institutional contexts, such as weak organizational legacy, affect the results of identity construction in functional terms. At last, the theoretical and practical implications both in organization and management of this study were well discussed.

In this paper, we propose a new prioritized Optical Burst Switching (OBS) protocol based on a hop count, which can provide efficient utilization in optical networks. Under several legacy schemes, a switch drops the burst with the shortest time regardless of its traversed hop count. As a result, a dropped burst that have been traversed many hops might cause increased bandwidth waste compared to one that has traversed a few hops. To improve this problem, we propose the Just Enough Time (JET) with a hop counting scheme which can reduce the wasted bandwidth by prioritizing the burst traversed many hops over others. From the simulation result, it is preyed, we show that the proposed scheme has advantages against legacy schemes in terms of the burst blocking probability and the link utilization.

I design and implement The Internet Messaging System(XML/EDI System), that is able to transform to user requested format as registering mapping script even though it was transferred any formatted message. Also, This system is able to easily migrate the existed Legacy System(ERP, MIS. etc). As basic service. I implement message sending message receiving, message retrieval, and mapping in Client system. And I support EDI, XML. DB. HTML that is selected among various message format.
