  • Quality of a new system is closly related to the quality of components in reuse repository. Quality assessment is essential to construct a reuse library. Definition of quality and method of assessment are totally different in reuse environments. User interface, functionality, performance are main factor in non-reuse development environment. However, reuse environment needs more reusability, extensibility, generality, and maintainability in quality assessment. This paper describes a development of quality assessment tool for multimedia object reuse conponents. Tool gets reuse components described by C++ or IDL, and analyses style, structure, coupling, strength, complexity, understandability, etc. Ultimatly the tool generate quality satisfaction degree for reuse programmers. Quality assessment services are supported in distributed object architecture, CORBA.

  • Objectives : The purpose of this paper was to examine quantitative methods for estimating and detecting local text reuse in the texts of East Asian Traditional Medicine. Methods : We introduce techniques that estimate the volume of local text reuse with n-gram and those that directly detect the reuse with the Smith-Waterman algorithm (SW algorithm). Based on this, the estimation and detection of local text reuse were carried out for 『Donguibogam』 and 『Huangdineijing·Suwen』. Results : Estimates with n-gram had more errors than methods with SW algorithms. SW algorithms detected suspected strings directly with local text reuse, resulting in more accurate results. Conclusions : Although n-gram does not accurately find local text reuse, its high speed makes it a preferable method for certain purposes, such as screening similar documents. On the other hand, SW algorithms have the advantage of being relatively good at finding similar phrases suspected as local text reuse even if the strings do not completely match. However, due to its excessive consumption of time and computing resources, its benefits are limited to cases where precise results are required.

  • The reuse of a programs is classified into white-box reuse to reuse with modification and black-box reuse to reuse without modification. A component in component-based development has the property of black-box reuse. In order to measure resuability of class and component, we must consider all the procedural and object-oriented attribute. In this paper, we propose a new model for measurement of class and component reusability and the measure criteria. A component that is measured by proposed model can know a degree of reuse and we can select which component is high in resuability.

  • This study is to seek for the reuse of vacant houses in the old settlement of urban area, focused on the Andeokbeol in Cheongju city, Korea. The following results were derived. Firstly, the maintenance and reuse methods of vacant houses are made for a number of house type as well as a variety of locational characteristics(flatland, gentle and steep slope) of the Andeokbeol. Secondly, reuse plans of vacant houses are established for a variety of classes such as local residents, artist and youth activist around cultural complex(Cheongju old cigarette factory), and outsiders. Thirdly, owners, users and intermediaries of vacant houses should find a solution to the reuse of them in company with Andeokbeol residents. And also institutional and administrative support measures are established for reuse of vacant houses.

  • This paper presents industry feedback and a case of improvement trial on enabling reuse driven software development which is one of several activities to improve software quality and productivity in a company which develops software that are embedded into consumer electronic products. Several case studies will be introduced that are related to software reuse strategies and practices to show how to establish environment for reuse basis in a company, how to apply it to development team and project and how to improve that through trials and errors. To enable reuse-oriented software development in a huge company, integrated and focused approach is needed among technical, management and environmental point of view. We tried to solve that problem in technical field with reuse method, in management filed with reuse metric and in environment field with reuse repository. The characteristics of our software development environment could be summarized as below. The first, embedded software which would not independent to hardware devices and the second, it is very huge company which develops extremely various products by many different organization with different domain characteristics and the third, development lead time is extremely short and many variation models are stems from basic models. We expect that our study would give contribution to industry struggling to solve similar problem for presenting our experience and could be a reference model for enabling software reuse in a real world practically.

  • In our country, most of the wood resources are imported. We faced a continuous rising of wood price by export country's some conditions and excess rising of transport charge, also a shortage of structural size members. In these situation, recycling or reuse of wood residues and wastes under wood processing industry, building construction and demolition is not a option but a prerequisite. In our country, there is a dearth of data on recycling or reuse of wood residues and wastes, so the investigation on the necessity of recycling or reuse of wood residues and wastes was conducted by using the foreign data and documents. First of all, fields and actual conditions for the domestic wood processing industry were surveyed. Then, kinds and signification of wood residues and wastes were organized. Later, the necessity and the signification of recycling or reuse of wood residues were investigated, and postulations for effective recycling and reuse were suggested. Above all, the necessity of grading standards for reuse or recycling and some important consideration for developing grading standards were emphasized. At last, foreign research tendencies and some applications on recycling or reuse of wood residues and wastes were supplemented.

  • In order to improve the efficiency of optimizing compilers, integration of register allocation and instruction scheduling has been extensively studied. One of the promising integration techniques is register allocation based on register-reuse chains. However, the generation of register-reuse chains in the previous approach was not completely systematic and consequently it creates unnecessarily dependencies that restrict instruction scheduling. This paper proposes a new register allocation technique based on a systematic generation of register-reuse chains. The first phase of the proposed technique is to generate register-reuse chains that are optimal in the sense that no additional dependencies are created. Thus, register allocation can be done without restricting instruction scheduling. For the case when the optimal register-reuse chains require more than available registers, the second phase reduces the number of required registers by merging the register-reuse chains. Chain merging always generates additional dependencies and consequently enforces the execution order of instructions. A heuristic is developed for the second phase in order to reduce additional dependencies created by merging chains. For matrix multiplication program, the number of registers resulting from the first phase is small enough to fit into available registers for most basic blocks. In addition, it is shown that the restriction to instruction scheduling is reduced by the proposed merging heuristic of the second phase.

  • Since software reuse and agile development methods are seen as ways to shorten development time and accept frequent requirement changes, respectively, there has been growing interest and research on integrating these approaches. But despite the increasing number of software companies which have successfully adopted agile development methods, there has been little research on reuse in agile methods to further improve productivity. In this paper, we identify a new type of reuse asset and propose a task factoring technique by taking advantage of iteration characteristics to support reuse in agile software development methods. In addition, we can apply the proposed technique and show prototyping of task reuse in a video rental application.
