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.

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 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.

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.

Software productivity and quality improvement through software configuration management is based on organized and consistent change management. In change management, artifact identified as configuration item should be able to provide its changed history to the members in group and the members should be able to track down the changes made for the corresponding artifact. General software configuration management systems provide tracking information for artifacts only within the configuration management system, and it does not go further to changes that occur within personal working space. This paper provides a solution that helps tracking down changes that occur not only in configuration management, but also personal artifact's changes through the integration of configuration management system and personal working space. A revised version in configuration management system is connected to the artifact version of the working space by the tagging technique, and traceability can be managed more effectively by sharing the tracking information.

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.

Beef traceability systems help prevent the distribution of Hanwoo (Korean native cattle) meat as imported beef. In particular, assigning a traceability number to each cattle can provide all information regarding the purchased Hanwoo meat to the consumers. In the present study, a DNA identity test was conducted on 344 samples of Hanwoo meat from large livestock product stores in Seoul between 2021 and 2022 to determine the authenticity of important label information, such as the traceability number. Traceability number mismatch was confirmed in 45 cases (13.1%). The mismatch rate decreased to 11.3% in 2022 from 14.7% in 2021, and the mismatch rate was higher in the northern region (16.9%) than in the southern region (10.2%). In addition, of the six brands, B and D showed satisfactory traceability system management, whereas E and A showed poor traceability system management, with significant differences (P<0.001). The actual traceability number confirmation rate was only 53.9% among the mismatch samples. However, examination of the authenticity of label information of the samples within the identified range revealed false marking in the order of the traceability number (13.1%), sex (2.9%), slaughterhouse name (2.2%), and grade (1.6%); no false marking of breed (Hanwoo) was noted. To prevent the distribution of erroneously marked livestock products, the authenticity of label information must be determined promptly. Therefore, a legal basis must be established mandating the filling of a daily work sheet, including the traceability number of beef, in partial meat subdivisions. Our findings can be used as reference data to guide the management direction of traceability systems for ensuring transparency in the distribution of livestock products.

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.
