The goal of product line engineering is to support the systematic development of a set of similar software systems by understanding and controlling their common and distinguishing characteristics. The product line engineering is a process that develops reusable core assets and develops a set of software-intensive systems from a common set of core assets in a prescribed way. Currently, many software development technologies are accomplished in context of product line. However, much of the product line engineering research have focused on the reuse of work products relating to the software's architecture, detail design, and code. The product lines fulfill the promise of tailor-made systems built specifically for the needs of particular customers or customer groups. In particular, commonality and variability play central roles in the all product line development processes. These must be treated already during the requirement analysis phase. Requirements in product line engineering are basis of software development just like as traditional system development engineering, and basis of deciding other core assets' property - commonalities and variabilities. However, it is difficult to elicit, analyze and manage correct requirements. Therefore, it is necessary to develop systematic methods which can develop and manage requirement as core asset, which can be stable in anticipative change and can be well adapted to unpredictable change. In this paper, we suggest a method of managing requirements as core asset in product line. Through this method, the reuse of domain requirements can be enhanced. As a result, the cost and time of software development can be reduced and the productivity can be increased.

The single-sourcing of content is extremely beneficial because when we are managing several projects with hundreds or thousands of documentation, we don't want to be changing the same content, or substantially similar content in multiple locations. The Darwin Information Typing Architecture (DITA) is an XML-based architecture for authoring, producing, and delivering technical documents. It consists of a set of design principles for creating Information -typed topic modules and for using that content in various ways. In this paper, we examine the approach of using The Darwin Information Typing Architecture for technical documents development to enhance the reuse of existing content components for difference information products.

Cost reduction, time to market, and quality improvement of software product are critical issues to the software companies which try to survive in recent competitive market environments. Software Product Line Engineering (SPLE) is one of the approaches to address these issues. The goal of software product line is to maximize the software reuse and achieve the best productivity with the minimum cost. In software product line, software components are classified into the common and variable modules for composition work. In this paper, we proposed a dynamic composition process based on aspect-oriented programming methodology in which software requirements are classified into the core-concerns and cross-cutting concerns, and then assembled into the final software product. It enables developers to concentrate on the core logics of given problem, not the side-issues of software product such as transactions and logging. We also proposed useful composition patterns based on aspect oriented programming paradigm. Finally, we implemented a prototype of the proposed process using Java and Aspect to show the proposed approach's feasibility. The scenario of the prototype is based on the embedded analysis software of telecommunication devices.

The purpose of Computer Aided Design is to design good products as quickly as possible. To do this, it is important to reuse the old designs and build on them. Most engineering designers, therefore. hale studied methods for reusing old designs, and the results of their study hale been applied to new designs Unfortunately, this only involves reuse of geometric data without design knowledge. If they can design products with the geometric data, including design knowledge, of the old designed and share them through the Internet, design efficiency will be improved. In other words, one way to improve designer's productivity is to share design information that includes knowledge and scattered data across design offices. This paper introduces a shared design environment with distributed knowledge-base. A product design environment based on distributed knowledge-base is proposed, which integrates the CORBA, OLE and WWW as the network architecture, a 3D CAD system, and an expert system shell. A design example of the lens barrel of a projection television is implemented to verify the idea.

Today, the tourism industry, unlike the past, is fused with various fields and is closely related to various fields, not just one field. In the case of the tourism industry, it leads to an increase in product sales through not only national import but also enhancing national image, forming a positive virtuous chain. As mentioned in order to verify the hypothesis presented in this study, pilot tests were conducted on about 50 copies of the data, and as a result, in-flight service (H1), flight service (H2), compensation service (H3), and reservation service (H4) It has been shown to have a positive effect on customer satisfaction, and when customer satisfaction is achieved, it naturally leads to reuse.

In today's increasingly data-intensive academic environment, data is becoming the foundation of academic communication as a research outcome rather than a research by-product. However, there is a limit to guaranteeing actual data reuse only by expanding the data supply or securing accessibility. In order to overcome this, it is necessary to understand the data reuse behavior and data needs in-depth. Therefore, this study attempted to identify the major data reuse behavior and data needs among researchers. To this end, the authors of KCI papers among the data reuse documents of the Korea Social Science Data Archive (KOSSDA) for the past 3 years were targeted. An in-depth interview was conducted with 12 researchers who accepted the interview. As a result, factors considered when reusing data were personal, economic, technical, and social aspects, and it was found that the data itself was used or contextual information of the data was used depending on the purpose of data reuse. The path to acquiring data is a web-based source of information, and a path through informal communication can also be found. In terms of the data needs, it was found that they prefer English, the United States, and institutional producers. Also they have a clear preference for quantitative data from an interviewer-filled interpersonal interview survey method, rich metadata along with raw data, and data that contains identification information. However, due to the lack of confidence in the value, it is negative for the use of data with controlled access and use, and it is difficult to confirm a clear preference because there is no similar data available for selection in terms of size and freshness.

This study attempted to investigate present condition and product planning of global eco-fashion brands that harmonize fashion and sustainability. As research subjects, this study selected 97 oversea fashion brands mentioned in books related to eco-fashion, Black(2011), Brown(2010), Fuad-luke(2009). As for research methods, materials and ethical practices of these selected 97 brands through literature data and their internet site homepages. This study analyzed oversea eco-brands collected 26 British brands, 22 American brands, 36 European brands such as Germany, France, Italy, Sweden, Spain, Finland and so on, except Britain and 13 other regions including Japan, India, Canada, Mexico, and New zealand. In conclusion, the product planning characteristics of these oversea eco-fashion brands can be summarized as follows; community and fair trade, ecological and slow design, recycle, reuse, redesign, and new eco-models. Firstly, brands of 'community and fair trade' manufactured products through fair trade and local community's artisan by ethical practices with organic fabrics. Secondly, brands of 'ecological and slow design' pursued timeless design and multi-functional design as luxury eco-fashion styles. They used organic textiles, hemp, bamboo, soya, tencell, sea cell, and self-sustaining plants. Thirdly, brands of 'recycle, reuse, redesign' aimed for upcycling high-end fashion and used vintage clothes, textile scraps, PET, parachutes, tires, safety belts, advertising banner and so on. In addition, brands of 'new models as eco-fashion' suggested zero-waste cutting, recycling over-printing technology, new sustainable business model, and ethical practices in the supply chain of the fashion industry.

PDM is an integrated solution for managing various kinds of document and information for a whole life~cycle of product management. PDM system spans a huge and complex area and requires so many efforts and budgets for development. A framework has been considered a promising way to improve productivity by reusing the software architecture, not just one part of the design or just source code. This was the reaSon why we developed PDM (Product Data Management) framework. Framework can reduce the time and efforts to develop a new PDM application. However, it also requires supporting environment since a framework is a big set of classes where their interactions are so complex. With this supporting environment, it is easy to understand the framework at a glance and easy to identify what hot spots to be refined to meet new requirements. In this paper, a new framework-supporting reuse environment based on the meta-repository was constructed for easy and convenient reuse.

The purpose of this study is to develop ICT utilization learning materials for a chapter titled 'Environment Friendly Clothing and Reform of Clothing' in technology and home economics textbooks for Year 2 students in middle school. The research methods were selected from ten types of junior high school technology textbooks, which were revised in 2009, and mainly focused on items such as jeans, shirts, shirts, cardigans, and skirts, Using selected textiles and basic design t-shirts, five works were made using structural and decorative details. The results of this study are as follows. First, textile products shown in the chapter 'Environment Friendly Clothing and Reform of Clothing' are most commonly worn and found in daily life. With regard to a reuse method, structural changes to clothing are proposed. For example, cases relating to the changing of a neckline or the use of a shirt or a sleeve are presented. There are some decoration methods adapted in reuse; using ornaments, such as spangles and emblems, patchwork, shirring and the constucting of collages. Second, following the plan, 5 items are designed with T-shirts, shirts, cardigans and skirts. For the T-shirt design, other fabrics including organza and neoplan are used from design point of view, in addition to reused textile products. Detailed structural changes of necklines, sleeves and collars and detailed and the ornamentation method including shirring, smoking, patchwork and collages are used. Third, this study proposes 6 categories (profile, design planning, diagram, reused textile product, production method and order and pictures of T-shirts developed) under the title of 'T-shirt Made Out of Disposed Clothing', selecting a blog as active teaching and learning material as a part of the ICT utilization in educational settings.
