The transition from manufacturing to service-based economies in highly developed societies during the post-industrial period resulted in the decline of the industrial landscape, leaving it abandoned or underutilized. In pursuit of revitalizing the obsolete industrial space, innovative design techniques based on adaptive reuse are applied to retrofit modern functions to create a new cultural space and preserve the historical, symbolic, and cultural importance of the abandoned industrial facilities. Design considerations based on facade redesign have proven to be one of the most adopted techniques that can help in recreating a new function for the vacant industrial buildings and integrating them into the present-day urban fabric. This paper examines the facade renovation elements used for the adaptive reuse of 15 abandoned industrial buildings presently used as multi-purpose facilities in South Korea. Through a questionnaire survey, this study analyzes the respondents' preference for different facade renovation elements in the 15 sites according to age and gender. The study found that both genders showed similar preference patterns between most elements. But on some elements, females were keener and expressed a stronger opinion than males. There were much more females than males who perceived color and material as the most important exterior elements. The findings of this study can be used for the adaptive reuse of industrial buildings according to user preferences for different facade renovation elements.

Each season, many clothing companies dump small pieces of fabrics left over from making samples. Since fabrics do not decompose easily, this results in environmental pollution. This research was done to discover effective ways to reuse these fabric remnants. As most of these remnants were not large enough for making clothes, fashion accessories was chosen as the design object. Four steps of design development process followed: information research & analysis, prototype design & sample making, market testing, final design decision. After market research and trend analysis, four neck decoration wear -- scarf & muffler(SM). collar & cape(CC), vest & top(VT), and necklace(NE) -- were selected as final product types. 45 designs arose, and 120 items with variations in fabric materials and colors were produced as samples. The three main themes (multiple. reversible, cross) were applied throughout all of the design items. Samples were evaluated from the reactions of the consumers through a 10-day sale at a retail store. Based on the sales record and customers' opinions, five designs from each of the product types SM, CC, and VT were picked out as final designs. In conclusion, fashion accessories turned out to be a more appropriate item to reuse fabric remnants from clothing companies than clothes were, because they necessitate small fabric size and the limitation in fabrics could be compensated with creative design ideas.

Increasing concerns of environment need to make change furniture field to more environmentally friendly approach, such as reuse of by-products from wooden products. As it is, the methods of recycling wood for industrial purposes have the advantage of productivity and adaptability. However, the industrial way is required a certain production facility of processing wooden by-products and has possible hygienic problems due to contaminated sources. Many designers have developed their own methods for reuse of wood in unique and artistic ways. Even so, because of confined sources, it could be not enough supply. Therefore, I developed the design methodology utilizing wooden by-products from S Design Company to relieve former ways' problems. The design suggestion took materials from a safe and abundant source. The wooden leftover pieces were connected together with epoxy clay, so previous process traces of furniture are remained as a decorative factor. Moreover, the synthesized material was able to be processed by ordinary woodworking facilities without additional installations. In doing so, console table focused on a commercial purpose and dining table for an artistic objective were successfully fabricated as final suggestions. In consideration of the proposal using wooden furniture leftovers, diverse recycling designs should be investigated for future reference.

Typical multi-tier client/server architecture includes various and complex objects scattered around the network. Those objects must be clearly identified and designed. Then, their interface must be well-defined so that the integration can be done without major difficulties. This paper presents an application framework to increase reuse and to accomplish architectural simplicity in information systems development. Each component of the architecture is identified and designed. The proposed architecture of the application framework provides the fundamental structure for developing individual functions of an information system. Resulting architectural simplicity achieves effective and efficient maintenance throughout the lifecycle of the information systems. Although the framework aims at the reuse within a project, the productivity of information systems development across projects will be greatly improved eventually. Cases are discussed to evaluate the practicality of the architecture presented.

Model-driven and component-oriented development is increasingly being used in the development of embedded systems. When combined, both paradigms provide several advantages, such as higher reuse rates, and improved system quality. Performing model-driven and component-oriented development should be accompanied by a component model and a method that prescribes how the component model is used. This article provides an overview on the MARMOT method, which consists of an abstract component model and a methodology for the development of embedded systems. The paper describes a feasibility study that demonstrates MARMOT's capability to alleviate system design, verification, implementation, and reuse. Results indicate that model-driven and component-based development following the MARMOT method outperforms Agile development for embedded systems, leads to maintainable systems, and higher than normal reuse rates.

Content is often developed inconsistently in technical authoring environments, as new documents are created and existing documents are revised. The Darwin Information Typing Architecture(DITA) is an XML-based, end-to-end architecture for authoring, producing, and delivering technical documentations. The core of most advanced authoring and publishing systems is the concept of content reuse. In this paper, we describe to design and implement an authoring and producing system of different technical documentations for the accreditation programs of Engineering Education using DITA XML. It provide a content reuse method for accomplishing the improvement of content consistency and the speed-up of the production in technical documentations.
