  • FORM(Feature-Oriented Reuse Method) is one of representative product line engineering methods. The essence of FORM is the FORM architecture models, which can be reused in the development of multiple products of a software product line. The FORM architecture models, however, have the following problems when applied in practice. First, they are not standardized models like UML(Unified Modeling Language) and therefore they can be constructed only through a specific modeling tool. Second, they do not represent architectural variability explicitly. Instead their variability is only managed through a mapping from a feature model. To address these two problems, we developed at first a method for representing the FORM architecture models using UML, which enables the FORM architecture models to be constructed through various available UML modeling tools. Also, we developed an effective method for representing as well as managing the variability of the FORM architecture models through a mapping from a feature model.

  • Component-based development(CBD) has acquired a substantial acceptance in both academia and industry as an effective inter-organizational reuse technology. A component framework in product line engineering(PLE) which consists of related components, connectors and their semantics has a greater potential for reusability than components. In frameworks, components are glued with association, dependency and connections. Problems occur like affecting the implementation code of components when they are glued and replaced because the association and dependency relationships between COTS components which are acquired for application development do not match exactly. Especially, a connector may not only connect related components, but also mate partially-matched COTS components fit together. However, little has been studied to date about connectors that can be used practically. In this paper, we present a meta-model for connectors and show how a connector can be designed and implemented in practice. We propose five main patterns of connectors. Proposed major patterns Provide design guidelines for practical and efficient connector configuration based on component framework. And also, applying techniques and applied case studies of the major patterns show greatly increased applicability and reusability of the component without component modification.

  • Today, many firms face the environment of high uncertainty and severe competition due to the rapid technology development and the diverse needs of customers. In the business environment, one of the most important ways to gain sustainable competitive advantage and future growth engine is related to NPD (New Product Development), which is a very important issue for practice and academia. Thus, this study intends to provide new values to practitioners and researchers related to NPD by analyzing current research trends and future trends in NPD field. For this, we bibliometrically analyzed keyword networks which consist of keywords that were already published in the eminent journals from Scopus database to generate insights that have not been captured in the previous reviews on the topic. As a result, we could understand the extant research streams in NPD field, and suggest the changes of specific research topics based on the connected relationships among keywords over the time. In addition, we also foresaw the general future research trends in NPD field based on the keywords according to preferential attachment processes. Through this study, it was confirmed that NPD keyword network is a small world network that follows the distribution of power law and the growth of network is formed by link formation by keyword preferential attachment. In addition, through component analysis and centrality analysis, keywords such as Innovation, New product innovation, Risk management, Concurrent engineering, Research and development, and Product life cycle management are highly centralized in NPD keyword network. On the other hand, as a result of examining the change of preferential attachment of keywords over the time, we suggested the required new research direction including i) NPD collaboration with suppliers, ii) NPD considering market uncertainty, iii) NPD considering convergence with the other academic areas like technology management and knowledge management, iv) NPD from SME(Small and medium enterprises) perspective. The results of this study can be used to determine the research trends of NPD and the new research themes for interdisciplinary studies with other disciplines.

  • Sesame was one of the economical crops in Korea. However, cultivation area of sesame has been decreasing rapidly due to the lack of mechanization for this crop and the opening of agricultural product market. Sesame seed is so small that ordinary seeder can not seed properly. In rural practice, farmers seed sesame with hand and do thinning after shoot emerges. Seeding and thinning in sesame cultivation take more than 40% of total labor To reduce labor in seeding and thinning, a pellet seed machine for sesame has been developed. The pellet seed machine is very simple in structure. It utilizes the chemical reaction between alginate solution and $CaCl_2$. Two material forms a membrane when they meet The uniqueness of the pellet seed machine for sesame were 1) a counter rotating roller for metering the mixture of activated carbon and alginate and 2) swinging plate for submerging seed into the mixture. The prototype machine can produce 30, 000 pellets per hour and costs ₩6, 891 per 1 km sesame.

  • In this study, significant factors influencing on the quality and stability of fermented sausage, such as materials, processing conditions, and microbiological characteristics as well as topography during ripening, were documented. Since most fermented sausages are not heated during manufacture or before consumption, a strict control of the growth of pathogens and the selection of favourable conditions that encourage the specific growth and development of desirable microflora are particularly important. With respect to microbiological safety, hurdles, i.e., preservations(nitrite), redox potential, competitive flora, acidity(pH), and water activity($a_{w}$) are matters of importance to prevent proliferation of bacterial pathogens. Today, for ensuring the safety and quality of the final product, the application of starter cultures in combination with the proper processing is subsequently used in practice. For improving the efficiency of microbiological utility in the production of fermented sausages, the understanding of their topography is essential. The documented different points must be taken into account when HACCP systems set up for the manufacture of fermented sausages. There are continuous researches concerning desirable improvements to sausage fermentation with health enhancing properties.
