In this paper, we propose a decision scheme of amount of required resources in wireless multi-hop systems which can reuse radio resources adaptively among relay stations (RSs). Base stations (BSs) can allocate resources dynamically based on amount of required resources of each RS. Moreover using resource reuse with this allocation method can increase amount of available resources in multi-hop systems. Generally, BSs allocate same amount of resources for RSs which share and reuses same resources for each other. Since amount of required resources are different among these RSs, a decision scheme of a specific value which can represent various required resources of RSs is needed. We propose this scheme which can decide the representative value of required resources of RSs adaptively based on the amount of required resources and the buffer state of each RS. Our simulation results show that the proposed scheme can increase performance of a multi-hop system. System capacity with the proposed adaptive scheme is increased by twice as large as one with a fixed representation value.

There is a growing interest and need for adaptive reuse and remodeling as a method for sustainable urban regeneration and residential improvement. The purpose of this study was to suggest implications for the remodeling of detached house for adaptive reuse in Korea. To this end, a theoretical review and case analysis was conducted on the remodeling in 'Gupo-Saetulmaul' and 'Haeridan-gil' in Busan City. The implications through the study are as follows. (1) Programs for residents participation and sustainable management of buildings are needed. (2) Coexist between residential and commercial use is needed. (3) A guideline for planning and designing street and building remodeling is needed at the level of the entire detached housing site.

Recently, distributed collaborative development environment has been recognized an alternative environment for product development in which multidisciplinary participants are naturally involving. Reuse of Product design information has long been recognized as one of core requirements for efficient product development. This paper addresses an image-based retrieval system to support product design information reuse. In the system, product images obtained from multi-modal devices are utilized to reuse design information. The proposed system conducts the segmentation of a product image by using a labeling method and generates an attributed relational graph (ARG) that represents properties of segmented regions and their relationships. The generated ARG is extended by integrating corresponding part/assembly information. In this manner, the reuse of assembly design information using a product image has been realized. The main advantages of the presented system are following. First, the system is not dependent to specific design tools, because it utilizes multimedia images that can be obtained easily from peripheral devices. Second ratio-based features extracted from images enable image retrievals that contain various sizes of parts. Third, the system has shown outstanding search performance, because we applied various information of segmented part regions and their relationships between parts.

As XBRL applications for sharing the contents and semantics of business reports get activated, it is increasingly necessary to reuse components systematically by the standardization in the national level. The current standardization of Korean electronic documents follows the "Guideline for XML Documents Development", which aims to maximize the reusability of components by providing a business library as well as the UN/CEFACT core components methodology. XBRL takes the same approach with the standardization of electronic documents in that their components (concepts and their structures) are defined using XSD. In XBRL, however, concept are restricted to specific types and diverse relationship types can be defined for associating the concepts to themselves and other additional information. As a result, there are some issues that may not be solved by just applying the guideline to XBRL. This paper presents a basic method for applying the methodology to XBRL applications in order to realize the systematic reusing and standardization of XBRL documents in the national level. For case analysis, FSS (Financial Supervisory Service) income statement is employed to demonstrate the possibility of the method.

In software development process, appropriate design can exist more than one. And software architectures can be restructured by modification and update during design processes. Therefore, the method that specify efficiently the modification elements of architectures, and manage different versions of architecture designed through various aspects is required. In this study, we propose software architecture restructuring mechanism that can restructure legacy architecture and a new software architecture designed with reuse of it in integrated form, and define specification elements and structure of the proposed restructured architecture specification. It provides the method that can reference and reuse architectures designed with various aspects of developers in architecture design processes. In addition, it supports flexible specification method for specification of modification elements such as revision, substitution, update of legacy software architecture.

Recently, self-adaptive system researches have been done to solve the problems occurred in the dynamic environment. Designing requirement in the self-adaptive system is necessary to recognize and solve the problem for the system, and if a developer reuses existing adaptation strategy to design the requirement, the designing time and cost would be reduced. Therefore, this paper proposes the system which extracts reusable adaptation strategy from the existing self-adaptive system. For the proposal, this paper conceptualizes the self-adaptation elements, defines the adaptation strategy ontology and target system ontology, and presents the process of extracting reusable strategy. This paper also implements proposed system and evaluates the reuse rate of the extracted strategy. As a result, the adaptation strategies extracted by proposed system are exactly operated, and the extraction method of proposed system shows higher reuse rate than a previous method.

In this paper, we designed data monitoring system using RFID for efficient data management of cinder reuse process, and for construction of unified system utilizing exact data. We constructed database, thesarus retrieval model to manage this database, and designed RFID model for monitoring system. The construction of data monitoring system for stable cinder reuse is the efficient method to develop realtime and automatic process.

In this paper, we propose dual-polarization technique which double the system capacity without increasing any other bandwidth. In theory, dual-polarization technique can double system capacity by using an orthogonal electromagnetic wave. However, cross-polarization interference and multipath interference degrade system performance in practice. To cope with this problem, we propose Cross Polarization Interference Canceller(XPIC) for ITS/DSRC system which can mitigate the XPI as well as multipath propagation interference. We also analyze and discuss its performance with relevant computer simulation results.

Component-based software development [CBSD] is a new paradigm of recent software development. CBSD was started from reuse of software and study on software component technique. In order to improve produce and quality of software development, there is study on reuse of components lively and how to develop, share, and manage components effectively. In this study, I would like to suggest a method that is able to simply test a new application system by developing systems developed individually into components, registering them, and combining them.
