This study applies the Technology Acceptance Model to grasp the effect of the food traceability system on consumer confidence and usage intention. To verify the causal relationships between the factors, the consumers who use grocery stores in Seoul were selected. From February 20, 2011 to February 28, 2011, a total of 300 copies of the questionnaire were distributed, and 284 copies except for those unsuitable for analysis were collected. SPSS 12.0 and AMOS 5.0 factors analysis and a reliability test were conducted, in older to validate the proposed hypotheses. The results are summarized as follows. First, the food traceability system bad a significant effect on the technology acceptance model. Second, the food traceability system bad a significant affect on consumer confidence. Third, the food traceability system bad a significant effect on usage intention. Fourth, the technology acceptance model didn't have a significant effect on consumer confidence. Fifth, the technology acceptance model and consumer confidence bad significant effects on usage intention. Based on these results, this study suggests useful implications for the food traceability system.

Traceability targets provision of information to stakeholders required for analyzing impacts among artifacts due to changes. Unlike single product development, in software product line developing the family of products the complexity of maintaining and managing traceability between two life cycles, domain and application engineering is so high. Accordingly, variability traceability management approach centred on orthogonal variability model that manages variability separated from development artifacts has been conceptually proposed, but its efficiency has not verified yet. This paper verifies whether orthogonal variability model based traceability can provide required traceability through an example. As the results, the OVM-based variability tracing method supports well to narrow down artifacts affected by the changes. However, the method does not support tracing the exact artifacts or exact part of an artifact affected by the change.

The ability to trace change history and dependency relations of software artifacts which are continuously changed has been recognized as an important factor that support quality management activities such as verification, validation, and testing in software system development process. General software configuration management systems provide tracing information for artifacts only within the configuration management system, and it does not go further to changes that occur within personal workspace. This paper provides a solution that helps tracing down not only changes of configuration items but also change history of artifacts existent in personal workspace through the integration of configuration management system and personal workspace. Furthermore, in cases of artifacts which are included in a configuration item, this paper provides a solution that support tracing dependency relations between the artifacts by identifying their version links. For the integration of configuration management system and personal workspace, a revision of configuration item is connected to the artifact's version of the workspace by the tagging mechanism, and traceability for change history and dependency relations of artifacts can be managed more effectively through integrated change process.

The Railroad Safety Technology R&D Program has been supported by the Ministry of Land, Transport and Maritime Affairs. The Program consists of dozen or more projects and thus is quite complex, which requires effective project management. This paper is discussing how to effectively manage the railroad safety technology R&D program based on systems engineering management plan (SEMP). The key issues dealt in this paper include the SE management, requirements management, verification and validation, integrated data base management, and traceability management. To achieve the goal, we first defined an appropriate SE process to be adopted in the program and the result was documented in the systems engineering management plan. According to the process defined, we set up the environmental frame in database. Using the database and SEMP, each project of the program was verified with respect to the corresponding requirements utilizing the traceability. All these efforts were carried out using a computer-aided SE tool, which enables efficient management of complex database.

Consumers have been requiring more higher level of food and agricultural products safety. The system of Good Agricultural Practice(GAP) has been spreaded over the world. Korea also introduced the GAP system in agricultural industry. GAP is related to the production side in the whole traceability system. The establishment of GAP system is a prerequisite to secure food safety. This study reviewed the concept of GAP and necessities and backgrounds of introducing the GAP system. Also, this study analyzed the problems which have been appeared in the GAP program and proposed the policy strategies and directions for the Korean GAP system. So issues for the GAP system are as follows; computerizing of traceability system, forming the cooperative works among the related governmental departments, establishing a certification system to relate with crop features, efficient management, ensuring distribution channel and the research for estimating GAP consumer surplus is need to analyze GAP program more efficient. In addition, It is necessary to keep the records of the data to analyze the GAP program more accurately.

We proposed a methodology to automatically extract the requirements from the documents and check the consistency and traceability among them. The documents include not only text but also PDF or image files. We also suggest a method to visualize the result with maps, numbers, and graphs. By comparing the results with those of manual reviews from experts, we show that it is necessary to use knowledge-based method in future instead of the wordbased method for improving the reliability. The results can be applied effectively for already existing documents.

It is well known that efficient management and thorough implementation of stakeholder requirements is vital for a successful development of a large-scale and complex system. Equally important is to make sure that all the requirements be correctly realized in the developed system. For the purpose, verification requirements are derived with traceability from the system requirements. This paper discusses a step by step process for constructing the requirements verification model which includes : 1) the schema modeling both requirements and their traceability; 2) the template documenting the verification requirements; 3) the verification model constructed from the schema; and 4) the test and evaluation plan that can be printed automatically.

This study investigates the impact of the attributes of the eco-friendly agricultural products traceability system on perceived value and behavioral intention. Empirical subjects are those who live in Seoul and Gyeonggi province, over the age of 20 and have experience of buying eco-friendly agricultural products though department stores, discount stores and specialized eco-friendly product stores. After distributing 550 copies of questionnaire from April 10th, 2013 to May 9th, 2013, 470 copies(85.5%) are used for a final statistical analysis of the survey after excluding the copies with biased opinions or missing values. The results of this study show sufficient theoretical base for future research by verifying a causal relationships between the attributes of eco-friendly agricultural products traceability system such as reliability, safety and innovation, and consumers' perceived value and behavioral intention. Therefore, producers should correctly record producing history base so that consumers can continue to use the system. The traceability system can not only satisfy consumers by enhancing transparent management and producing systems for eco-friendly products but also guarantee us to eat all products we get without worries.
