Insufficient requirement management accounts for 54% ofunsuccessful software development projects and 22% of insufficient requirement management comes from requirement change management. Hence, requirement management activities are important to reduce failure rates and a tracing method is suggested as the major factor in requirements change management. A traceability table is easy to use because of its legibility accurate tracing. However, traceability tables of existing studies have failed to concretely suggest method of change management and effect of traceability. Also, studies of methods to estimate change impact is complex. Hence, this study suggests how to use a traceability table to manage changes in requirements. Together, in comparison to existing studies, this study suggests easier methods to estimate change rate and change impact. Also Fifteen projects were sampled to test the hypothesis that traceability table influences the success of projects and that it decreases the failure rate that comes from the insufficient requirements management.

The agro-livestock industry is composed of a complicated supply chain and the customer‘s interest in safety of agro-livestock products is increasing. In order to provide customer with the accurate information about the history of product, and make good use of these information, traceability systems based on RFID technology were implemented and are planned. It is, however, difficult to make the efficient flow of information and to enhance or expand the traceability system because of the lack of the standard of RFID code system. To overcome this problem, we propose a RFID code system for the traceability of argo-livestock products on the basis of ISO/IEC 15459 KKR code system.

In this study, IT based traceability system which is able to measure weight and moisture content of grain in the post-harvest process of intake, drying, storage and milling was developed in RPC(Rice processing complex). Measured information of weight, moisture content, yield, loss and quality was saved in the DB sever. Simultaneously, lot No. was generated and connecting to quality and traceability information. Also, automatic control system with MMI(Man Machine Interface) and yield and inventory control system(YICS) for grain was developed for the traceability system by applying the TCP/IP communication. In addition, simulation of system was performed for evaluation in RPC.

Requirements traceability enables to reuse various kinds of software artifacts, which are the results from software development life cycle, rather than reuse source code only. To support requirements traceability for reuse of software artifacts, 1) artifacts should be described based on requirements and 2) a requirements tracing method should be supported. In this paper, we provide a description model for annotating requirements information to software artifacts by using requirements ontology. We also provide semantic tagging method users to efficiently annotate artifacts with the requirements ontology. And we finally present how requirements traceability is supported based on requirements ontology and also suggest the system architecture for requirements traceability support.

The u-SCM to persue unification of the whole Supply Chain through ubiquitous computing and technical interface is raised its head for enterprise to secure endless competitive advantage and grow up constantly. This can be especially a matter of primary concern for business process elevation on various industry. The other side, The Traceability Service propelled both nationally and internationally is propelled specific industry to offer visibility and traceability of each manufacture on supply chain related to induce RFID, but standard Traceability Service Architecture isn't decided yet. This paper propose Model of Product Traceability Service which is based on EPCglobal Network to be the whole world standard architecture for the sake of efficient and perfect manufacture management on entire supply chain based on RFID.

The effectiveness of genetic markers on Hanwoo traceability systems was applied and evaluated from Korean 33 Hanwoo elite sire families. Five microsatellite markers were selected finally, which were located on chromosomes different chromosomes with the end sequencing of 100 HW-YUBAC that were recorded in the NCBI by Yeungnam University. Eleven major microsatellite markers were selected from allele amplified, their frequencies, H(Heterozygosity) and PIC(Polymorphism information content) with Hardy-Weinberg equilibrium. Next, in order to evaluate the power of the markers selected on the individual animal identification with experimental condition, the match probability(MP) and the relatedness coefficient(R) were computed.

In RFID-based SCM, The traceability and product information is the important target data. In this paper, efficient items traceability model and the integrated model of the product between RFID network and GDS(Global Data Synchronization) network are studied. Information consists of the dynamic data generated from RFID network and static data generated from GDS Network. The integrated model will provide the interoperability between 2 kinds of networks.

This paper describes the project for constructing a traceability system for producing using RFID antenna in 900MHz frequency band and the consideration. In this project we reviewed analysis of properties classified by production process and RFID system through each frequency band, and designed a single unit RFID reader including antenna. The developed antenna is optimized to a field condition and this paper will show the test results. Also, we designed a single unit RFID reader by adding a reader to a designed antenna and explained the rule of tag memory allocation. Lastly, after running the system we could calculate visible and invisible effects of operation results and check up a wide possibility of application for RFID.

Software inspection is widely believed to be an effective method for software verification and validation (V&V). However, software inspection is labor-intensive and, since it uses little technology, software inspection is viewed upon as unsuitable for a more technology-oriented development environment. Nevertheless, software inspection is gaining in popularity. KAIST Nuclear I&C and Information Engineering Laboratory (NICIEL) has developed software management and inspection support tools, collectively named "SIS-RT. "SIS-RT is designed to partially automate the software inspection processes. SIS-RT supports the analyses of traceability between a given set of specification documents. To make SIS-RT compatible for documents written in Korean, certain techniques in natural language processing have been studied [9]. Among the techniques considered, case grammar is most suitable for analyses of the Korean language [3]. In this paper, we propose a methodology that uses a case grammar approach to analyze the traceability between documents written in Korean. A discussion regarding some examples of such an analysis will follow.
