Concerns about food safety continue to rise and under this situation, governments of some countries have reinforced their regulations more strictly for food safety. In order to prevent food safety incidents or, at least to minimize the impact, the preparedness is very important. As a consequence of this, traceability system has become an essential tool for food safety. Recently, it requires more prevention-based food safety control system. One of the most generally used systems for food safety control is Hazard Analysis and Critical Control Point (HACCP). Both traceability and HACCP systems can be integrated through Electronic Product Code (EPC) Sensor Network technologies which have four value propositions. In this paper, we will introduce the concept of product and process traceability system (P2TS) through the integration of three systems to improve food safety management. The final aim is to find out the added values of the P2TS.

Architectual environment in this study means a language and meaning complex which makes communication between human beings and environment possible. The purpose of this study is to propose a semiotic approach to analyze and examine meaning, as a semiotic system, and its effects, focusing on the generative meaning in the relationship between human beings and environment. For this purpose, it examines the academic status of modern semiotics in postmodernism and the possibility of its being metalanguatge for a study of a variety of cultural phenomena and desigv. It also provides two viewpoints as propositions for its analysis: it explains the necessity of environmental-discoursive attitude and social-semiotic viewpoint which understands environment as social-cultural reflectors. Finally, it provides framework and all the interpretative procedures for analysis of environmental meanings on the basis of the approach of semiotics of space. By applying the methods proposed this study to the case studies, it also proves validity of this approach and the potentialities of the application of semiotics. This study emphasizes not only denotative configuration of the architectural environment but also its connotative meanings. It maintains that designers, architects, and theorists should realize correctly today's changed value system and social and aesthetic paradigms. It also stresses the necessity of development of the new architectural language and meaning system.

This is an era in which companies should realize sustainable management through business models that propose social values beyond financial benefits and solve social problems. Accordingly, the role of corporate designers should be extended to social value propositions and materializations, including corporate profit-seeking. Among the members and organizations of the company, design organization and designers have strengths in terms of humanities and creativity compared to other organizations and members. We should actively seek opportunities for corporate designers to find the context of connecting businesses and society on their own, actively seek opportunities to integrate them with corporate design, expand the role of corporate designers through creative ideas, and actively pursue sustainable and wide social career development that encompasses both inside and outside of the company. To this end, we suggested three transitions of thougths to change the perception of fixed and straight-line forms of enterprise organization, enterprise design approach and product development process so far to present useful insights through case studies, how enterprise designers can accommodate social impact through new communication and access.

Purpose - Our study aimed to examine the roles of conflict management in maintaining a sustainable good relationship between joint venture (JV) partners. Although the concepts of relational capital, mutual commitment, and cultural adaptation have been neglected in previous research on interorganizational relationships, we treated them as inter-partner fit mechanism capabilities of affecting the level of satisfaction in a relationship with a JV partner. Design/methodology - In order to test hypotheses, we sent a questionnaire to Japanese firms operating JVs in South Korea and asked whether their levels of satisfaction with their JV partners increase when conflict management techniques are used to reduce the conflicts that usually arise between partners. Findings - The results of our study suggested that it is important for firms participating in a JV to construct and reinforce an inter-partner fit mechanism that enables them to maintain a favorable partnership. In addition, we suggested that relational capital, cultural adaptation, and mutual commitment influence conflict reduction and the level of satisfaction experienced in JVs. Moreover, the results showed that conflict management has a significant effect on developing soild partnerships and performance in JV situations. Originality/value - We advanced a new paradigm about conflict management and suggested methods of research propositions that are well grounded in the latest findings in conflict management research pertaining to JVs.

The rates of technological innovation and environmental change as well as market competition have recently accelerated, which makes it difficult for firms to satisfy the needs of their customers through existing product innovation or limited services. Some firms have attempted to find the solutions to this problem by conducting business model (BM) innovation. This study reviews the theoretical discussion to BM innovation and suggests propositions concerning the necessity of BM innovation and conditions of successful BM innovation. Furthermore, the study examines the applicability of the propositions and draws strategic implications by analysing the cases of two world-wide leading firms, AVL and ETAS, in the automobile R&D service sector. In particular, the study investigates how the firms with technological competence in the R&D service sector obtain market performance through BM innovation. Results of this study show that the case firms recognize the necessity of BM innovation based on product (or technology)-service fusion to effectively propose customer value and create corporate profit. Also, the firms exploit firm-specific complementary assets for successful BM innovation. This paper contributes to the literature of innovation management by promoting academic discussion concerning BM innovation in Korea and suggesting strategic implications for further development of R&D service sector and related firms in Korea.

The aim of this article is to propose a framework for standardization of knowledge based on a case study of clinical operation to guide initial hospital knowledge management projects. Both quantitative and qualitative data for the project from 2009 through 2012 were collected for analysis. In a study of knowledge management project of a lab in S Hospital's Eye Center, this research examines the standardization of operational knowledge for competence enhancement of the lab. The lab defined and standardized the knowledge concern of the lab operation and the in-group from 2008. Organizations are often unaware of the potential value of tacit knowledge in both clinical and administrative area. The main finding from the case study is that analysis of such tacit knowledge of a lab in a hospital can be transformed into explicit knowledge for organizational capabilities such as improved quality, responsiveness and competitive advantage. Concepts from Nonaka's theory are used to investigate processes of knowledge standardization, examining the strategic value of tacit knowledge and the need to rely primarily on internal documentation processes. Since there has been limited research on hospital knowledge management. it may also be useful to researchers in generating propositions for further study.

Many software reliability growth models(SRGM) have been proposed since the software reliability issue was raised in 1972. The technology to estimate and grow the reliability of developing S/W to target value during testing phase were developed using them. Most of these propositions assumed the S/W debugging testing efforts be constant or even did not consider them. A few papers were presented as the software reliability evaluation considering the testing effort was important afterwards. The testing effort forms which have been presented by this kind of papers were exponential, Rayleigh, Weibull, or Logistic functions, and one of these 4 types was used as a testing effort function depending on the S/W developing circumstances. I propose the methology to evaluate the SRGM using least square estimater and maximum likelihood estimater for those 4 functions, and then examine parameters applying actual data adopted from real field test of developing S/W.

Internet computing is a disruptive IT innovation. Semantic Web can be considered as an IT innovation because the Semantic Web technology possesses the potential to reduce information overload and enable semantic integration, using capabilities such as semantics and machine-processability. How should organizations adopt the Semantic Web? What factors affect the adoption and diffusion of Semantic Web innovation? Most studies on adoption and diffusion of innovation use empirical analysis as a quantitative research methodology in the post-implementation stage. There is criticism that the positivist requiring theoretical rigor can sacrifice relevance to practice. Rapid advances in technology require studies relevant to practice. In particular, it is realistically impossible to conduct quantitative approach for factors affecting adoption of the Semantic Web because the Semantic Web is in its infancy. However, in an early stage of introduction of the Semantic Web, it is necessary to give a model and some guidelines and for adoption and diffusion of the technology innovation to practitioners and researchers. Thus, the purpose of this study is to present a model of adoption and diffusion of the Semantic Web and to offer propositions as guidelines for successful adoption through a qualitative research method including multiple case studies and in-depth interviews. The researcher conducted interviews with 15 people based on face-to face and 2 interviews by telephone and e-mail to collect data to saturate the categories. Nine interviews including 2 telephone interviews were from nine user organizations adopting the technology innovation and the others were from three supply organizations. Semi-structured interviews were used to collect data. The interviews were recorded on digital voice recorder memory and subsequently transcribed verbatim. 196 pages of transcripts were obtained from about 12 hours interviews. Triangulation of evidence was achieved by examining each organization website and various documents, such as brochures and white papers. The researcher read the transcripts several times and underlined core words, phrases, or sentences. Then, data analysis used the procedure of open coding, in which the researcher forms initial categories of information about the phenomenon being studied by segmenting information. QSR NVivo version 8.0 was used to categorize sentences including similar concepts. 47 categories derived from interview data were grouped into 21 categories from which six factors were named. Five factors affecting adoption of the Semantic Web were identified. The first factor is demand pull including requirements for improving search and integration services of the existing systems and for creating new services. Second, environmental conduciveness, reference models, uncertainty, technology maturity, potential business value, government sponsorship programs, promising prospects for technology demand, complexity and trialability affect the adoption of the Semantic Web from the perspective of technology push. Third, absorptive capacity is an important role of the adoption. Fourth, suppler's competence includes communication with and training for users, and absorptive capacity of supply organization. Fifth, over-expectance which results in the gap between user's expectation level and perceived benefits has a negative impact on the adoption of the Semantic Web. Finally, the factor including critical mass of ontology, budget. visible effects is identified as a determinant affecting routinization and infusion. The researcher suggested a model of adoption and diffusion of the Semantic Web, representing relationships between six factors and adoption/diffusion as dependent variables. Six propositions are derived from the adoption/diffusion model to offer some guidelines to practitioners and a research model to further studies. Proposition 1 : Demand pull has an influence on the adoption of the Semantic Web. Proposition 1-1 : The stronger the degree of requirements for improving existing services, the more successfully the Semantic Web is adopted. Proposition 1-2 : The stronger the degree of requirements for new services, the more successfully the Semantic Web is adopted. Proposition 2 : Technology push has an influence on the adoption of the Semantic Web. Proposition 2-1 : From the perceptive of user organizations, the technology push forces such as environmental conduciveness, reference models, potential business value, and government sponsorship programs have a positive impact on the adoption of the Semantic Web while uncertainty and lower technology maturity have a negative impact on its adoption. Proposition 2-2 : From the perceptive of suppliers, the technology push forces such as environmental conduciveness, reference models, potential business value, government sponsorship programs, and promising prospects for technology demand have a positive impact on the adoption of the Semantic Web while uncertainty, lower technology maturity, complexity and lower trialability have a negative impact on its adoption. Proposition 3 : The absorptive capacities such as organizational formal support systems, officer's or manager's competency analyzing technology characteristics, their passion or willingness, and top management support are positively associated with successful adoption of the Semantic Web innovation from the perceptive of user organizations. Proposition 4 : Supplier's competence has a positive impact on the absorptive capacities of user organizations and technology push forces. Proposition 5 : The greater the gap of expectation between users and suppliers, the later the Semantic Web is adopted. Proposition 6 : The post-adoption activities such as budget allocation, reaching critical mass, and sharing ontology to offer sustainable services are positively associated with successful routinization and infusion of the Semantic Web innovation from the perceptive of user organizations.
