  • Component-based Development (CBD) is gaining popularity as an effective reuse technology. Especially commercial-off-the-shelf (COTS) components are mainly for inter-organizational reuse, rather than intra-organizational reuse. One of the essential tasks in CBD is to reuse the right components that provide the functionality and interface required by component consumers. If candidate components provide a limited applicability and customizability, a component consumer cannot reuse the components in application development. To resolve this partial matching problem, we need smart connectors that fill the gap between candidate components and the specification of components required. Previous researches about smart connector describe only connector types to resolve mismatch problems. However, previous researches do not address the identification and design method to resolve the problems. In this paper, we suggest taxonomy of various mismatch problems to identify partial match problems between requirements of the application and components. We identify smart connector types and suggest a systematic process for designing smart connectors using the taxonomy. Therefore, components that have the problems can be used to develop applications.

  • In order to evaluate the environmental load occurring from the whole life cycle of a facility, LCA (Life Cycle Assessment) adopted by ISO is not only applied as an individual product but rather a complicated system involving buildings and/or infrastructure in a wide range of scope. The introducing of LCA to a wastewater reuse facility will assist to understand not only the treatment of water contaminants but also the overall system related to the interaction of involved, potential issues. This research implemented LCA for the establishment of the wastewater reuse facility. The results show that a fresh water aquatic Eco-toxicological Impact (88.3%) is the largest environment concern and the maintenance & operation phase has the most impact on the environment utilizing life cycle for the wastewater reuse facility. The civil works and chemical treatments in the maintenance & operation phase led to the biggest environmental impact. The results of this research can provide pertinent data of investigating opportunities for environmental improvement not limited to public officers regulating environmental policies, and could be used to make decisions for an environmentally sound and sustainable design in the initial phase of construction.

  • We propose an interference space reuse (ISR) algorithm for the MU-MIMO design in 3-cell downlink interference channels. Also, we provide a strategy for the adoption of the ISR scheme in the cellular network. In the multicell interference channels, the cell edge users may undergo severe interferences and their signals should be protected from the interferers for reliable transmissions. However, the intra cell users do not only experience small interferences but also they require small transmission power for stable communication. We provide a vector design algorithm based on ISR, where intra cell users are served through reusing the cell edge users' interference space. The performance enhancement reaches 20% compared to the fractional frequency reuse (FFR) scheme combined with IA through the scheduling between the cell edge users and the intra cell users. Also, it can be used to enhance the cell edge throughput when the quality of service (QoS) requirements of the intra cell users are fixed.

  • High efficiency production requires the improved performance of CAD/CAM system. Although the CAD and CAM have been significantly developed over the last three decades, they must still study on the reuse of information during process. In this study, we developed a new integrated CAD/CAM system which can reuse the information generated in previous processes, in order to improve its performance. In addition, the developed system was verified by comparing with working-time, and system reproducibility was also examined with tolerance in the unmanned operation. Experimental results showed 58% reduction in working-time of 2D Auto-CAM module, 80% in case of 3D Auto-Exchange module, and 54.5% in case of Auto-Design module.

  • The purpose of this study is to establish a relationship between TV home shopping model and the marketing data of the TV home shopping industry. Differences in relationship marketing factors, trust, and intent to reuse depending on the experience of the model have resulted in a higher assessment of both the expertise and service factors of fashion stylists than groups with 10 years or less experience. In addition, model groups with 15 or more broadcasts in one month rated the professionalism, communication, ties, trust, and intent to reuse fashion stabilists more than 15 model groups. The difference in marketing factors, services, communications and ties between the professional and use of home shopping models was found to be 40 years old as compared to those in their 20s and 30s. Finally, in terms of the gender of the home shopping model, the difference between the marketing factors and the reliability of the relationship and the intent to reuse, the professional, communication and bonding, trust, and re-purpose factors were all rated higher by the female group than the male group. The results of the study suggest that a relationship marketing strategy needs to be established between a fashion stylist and a TV home shopping model, and fashion stylists should be judged based on the characteristics of a TV home shopping model.

  • The purpose of this study is to investigate the reasons for users to use accommodation applications and thefacts that affect reuse, and to suggest a design that can be used more conveniently for users. O2O services have diversified as more generations are enjoying leisure activities and the mobile market is expanding. Especially, the most important service in leisure activities is accommodation service. For the study, we surveyed about using accommodation application for 103 men and women in their 20s and 30s. Surveys shows that the main reason for users to reuse application is discounted services through events. Therefore, we will suggest anew design by collecting the inconveniences of users when using applications. We hope that the accommodation market can be expanded not only in Korea but also overseas markets by improving the services users, who use accommodation application, want though this study.

  • The problem of software reuse is dealt in two approaches. One is to build a new software by composing of the built-in components, and the other is to reuse architectural patterns that most of software system is generally composed of. Although the two approaches are important in design of software architecture, we could find outstanding difference in what kind of building blocks they use. The component based software design makes uses of building blocks whose contents are filled in by someone, on the other hand, the architectural pattern based software design is not interested in the contents of building blocks, but in the framework for building blocks including relationship of the building blocks. The paper purposes to find architectural patterns which are commonly found in diverse applications and help software architects reuse them in the software design process. We refine the architectural styles which is the well-known concept for software architecture design, and refine them as architectural components or templates which can be parts of software architecture.

  • In order to reuse a register transfer level (RTL)-based IP block, it takes another architectural exploration in which the RTL will be put, and it also takes virtual platforms to develop the driver and applications software. Due to the increasing demands of new technology, the hardware and software complexity of organizing embedded systems is growing rapidly. Accordingly, the traditional design methodology cannot stand up forever to designing complex devices. In this paper, I introduce an electronic system level (ESL)-based approach to designing complex hardware with a derivative of SystemVerilog. I adopted the concept of reuse with higher levels of abstraction of the ESL language than traditional HDLs to design multiplication server farms. Using the concept of ESL, I successfully implemented server farms as well as a test bench in one simulation environment. It would have cost a number of Verilog/C simulations if I had followed the traditional way, which would have required much more time and effort.

  • 디자인 패턴은 소프트웨어 -특히, 객체지향 소프트웨어- 의 개발시 재 사용성을 높기 위해서 사용되며, 이는 상속(Inheritance)과 같은 코드레벨 재사용 (code reuse) 보다 높은 레벨의 디자인 재사용 (design reuse)을 가능하게 한다. 디자인 패턴은 구체적인 문제에 대해 구체적인 해를 제공하는 cookbook과는 달리, 추상적인 문제에 대해 추상적인 해를 제시함으로써, 비슷한 부류의 문제에 적용할 수 있으므로 높은 재 사용성을 보장한다. 본 논문은 Retargetable한 특성을 갖는 Instruction set simulator의 개발에 디자인 패턴을 적용한 예를 보여줌으로써, 재 사용성 및 확장성을 높이는 방안을 소개한다.
