The EPCglobal Network is a system which provides the information of items to suppliers, consumers, and customers by granting identification numbers on the goods based on the technologies of EPC(Electronic Product Code) and RFID(Radio Frequency Identification), and connecting the space to store those information by network. The EPCglobal architecture framework is also a service consolidating supply and process chain by using EPC for the common goal of business corporations. In the national level, it is necessary to define standard vocabularies for each location and logistics business process for RFID environment using the pre-constructed logistics information infrastructure. Therefore, we define the standard vocabularies and partially user vocabularies for international logistics on EPCglobal network architecture. Finally, we believe that our vocabularies contribute to describing the events fur the EPCglobal network architecture and actually providing usable platform via the XML implementation.

These days RFID application has been developed rapidly. It has been applied to many business areas such as logistics and supply chains. The Electronic Product Code (EPC) Network Architecture, an open global standard, is proposed by EPCglobal for developing RFID enabled systems. People who want to obtain the product information which are master information and event information have to apply with EPC Network Architecture. However, EPCIS which has master information and event information has to be accessed base on each EPC. Therefore, there is lots of duplicate accessing to EPCIS because RFID application has to access the same EPCIS over again which makes all performance down in EPC Network. This paper proposes how to reduce access times to EPCIS using EPC grouping based on EPCIS address. We build EPC Network environment to experiment about performance of RFID application system and we prove the improvement of EPC Network. Our result shows the reducing the EPCIS communication time by maximum 99 percentages.

The purpose of this study is to analyze Hanwoo usage in school foodservices and to develop menus of lean cut Hanwoo. As a result, satisfaction of students, parents and teachers all increased regardless of school type after using Hanwoo. The high price compared to other meats (3.98) was the biggest difficulty for using lean cut Hanwoo followed by reduced taste preferences (2.84), lack of parent awareness (2.67) and lack of appropriate cooking facilities (2.13). According to the survey on how to increase the usage of lean cut Hanwoo, improvement of meat tenderness (3.80), development of various sauces (3.74) and development of seasoning for existing menu (3.61) were identified as major necessities. This analysis of Hanwoo utilization in school foodservice was used to develop menus of lean cut Hanwoo. The menu was particularly developed to overcome the supply-demand imbalance of different cuts. For the menu development process, potential Hanwoo utilization in school foodservice, cooking method, and diverse taste were considered. In order to evaluate the applicability in school foodservice, JARS was used and the final eight menus were selected. For the selected menu, a nutrition analysis was conducted. Further, systematic recipes with a mixing ratio;product process description and a simplified product process were also developed.

Purpose The high-technology market shows characteristics of a highly interdependent network market in both supply-side and demand-side, compared to other markets. Particularly, for convergence products, connectivity with related elements, as well as characteristics of innovation itself, is relatively important to the extent that they combine functions provided by several devices into a single device. Therefore, this study aims to identify whether network externality exists in value and adoption of a convergence product and discover a source of network externality, if any. Design/methodology/approach: Through a preceding research analysis and a literature review, 'social influence' and 'network size' have been drawn as direct network elements. On the other hand, general (comprehensive) concept compatibilities including 'intra-technology compatibility', 'inter-technology compatibility' and 'complementary-technology compatibility' are regarded as indirect network elements. Findings: Major findings are as followed;- First, it is shown that the factors influencing on perceived value of a convergence products are 'social influence' and 'network size' as the direct network elements and 'complementary-compatibility' among indirect network elements. Second, it is also found that 'intra-technology compatibility', 'inter-technology compatibility', 'complementary-compatibility' and 'perceived value' have significant effects on adoption of a convergence product. Particularly, it is known that 'complementary-compatibility' is an important source of network externality as it plays a decisive role in value judgment and has significant effects on perceived value. It is worthwhile to notice that this study comprehensively explains effects of network on high-tech products by structuring comparability as a multi-dimensional concept, as well as direct network elements.
