Most of systems engineers make a traceability matrix and attach it to their technical documents as a result of systems engineering activities. I have been working in the field of systems engineering for many years and have been watching traceability matrices created by systems engineers or developers from various companies. I have been thinking that some of them are not suitable in terms of purposes of traceability matrix. In this paper, I would like to suggest a right template for the traceability matrix in conformance to traceability purposes. The key is that traceability matrix should be created from higher level of requirements to current level of requirements.

This study examined the usage, perception and willingness to use beef traceability. The data were collected from 255 housewives in Busan and Gyeongnam region through a self-administered questionnaire. Frequency, Cronbach's ${\alpha}$, t test, one-way ANOVA, Duncan's multiple range test, Pearson's correlation analysis, and multiple regression analysis were conducted by SPSS Windows V.20.0. Only twelve percent of the respondents experienced to use beef traceability. Most respondents checked it by kiosk or bar code reader in a store. On the other hand, eighty-eight percent did not use beef traceability. The reasons for not usage of it were "Do not know beef traceability very well", "Do not know how to use beef traceability", and "Information from packing or counters is reliable" in order. In the level of perception of beef traceability, safety assurance was highest, followed by information quality, usefulness, and information accessibility. The percentage of correct answers of knowledge about beef traceability was not high. The multiple regression analysis showed that employment status, knowledge about beef traceability, information quality, information accessibility, and usefulness were significant factors to affect the willingness using beef traceability.

Recently, fisheries safety has been a matter of primary concern among consumers and suppliers. This phenomenon made them require the introduction of fisheries traceability systems. For traceability systems to be effective, automatic identification means play an important role. Therefore, RFID-based fisheries traceability systems are more required than barcode-based fisheries traceability systems. Unlikely EU and Japan, Korea did not accept mandatory traceability regulations. But Many countries began to accept mandatory traceability regulations to diminish food risks. So Korea is expected to adopt them in the near future. The purpose of this study is to find what benefits are generated from the adoption of RFID-based fisheries traceability systems and are related to their success. To do these, this study investigated primary benefits of RFID-based fisheries traceability systems from the perspectives of consumers and suppliers. Consumers' benefits were derived from the perceived risk dimensions. And suppliers' benefits were derived from operational benefits of RFID systems. To purify the benefits from RFID-based fisheries traceability systems, reliability and factor analysis were used. And the refined benefits of RFID-based fisheries traceability systems were additionally analyzed to find which benefits were significantly related to fisheries traceability systems' success. According to the analysis results, all risk dimensions except social risk were significantly related to their success. But in the benefits of suppliers, only "recalls and counterfeits" factor was significantly related to their success. These results implied that fisheries traceability systems should be based RFID technology instead of barcode and fisheries traceability systems were related to almost food risk dimensions. It's because these significant factors are related all food risks except social risk and the benefits of suppliers can be derived from only RFID technology.

Current food-traceability platforms suffer from problems such as inconsistent traceability standards, a lack of public credibility, and slow access to data. In this work, a combined code and identification method was designed that can achieve more secure product traceability using the dual anti-counterfeiting technology of a QR code and a hidden code. When the QR code is blurry, the hidden code can still be used to effectively identify food information. Based on this combined code, a food-safety traceability platform was developed. The platform follows unified encoding standards and provides standardized interfaces. Based on this innovation, the platform not only can serve individual food-traceability systems development, but also connect existing traceability systems. These will help to solve the problems such as non-standard traceability content, inconsistent processes, and incompatible system software. The experimental results show that the combined code has higher accuracy. The food-safety traceability platform based on the combined code improves the safety of the traceability process and the integrity of the traceability information. The innovation of this paper is invoking the combined code united the QR code's rapidity and the hidden code's reliability, developing a platform that uses a unified coding standard and provides a standardized interface to resolve the differences between multi-food-traceability systems. Among similar systems, it is the only one that has been connected to the national QR code identification platform. The project has made profits and has significant economic and social benefits.

식품사고의 발생은 제품에 대한 소비자의 신뢰를 실추시키기 때문에 사회적으로 큰 문제가 아닐 수 없다. 식품의 유통구조가 복잡한 현대사회에서 소비자는 자신이 구매하려는 제품이 누가 언제 어떻게 생산했는지, 어떤 가공과정을 거쳤는지, 구입 제품이 어떻게 전달되는지 등 제품에 대한 정보를 확인하기 어렵고 식품안전 문제에 대처하기가 어려운 상황이다. 이는 제품의 공급자와 구매자(정보이용자)간에 정보의 비 대칭화에서 비롯된다고 할 수 있다. 따라서 식품안전문제를 해결하기 위해 정부에서는 관련법을 정비하고 시범사업을 추진하고 있으며 공급업체들은 제품에 대한 정보를 확인할 수 있는 보다 체계적인 시스템을 도입하는데 많은 관심을 보이고 있다. 본 연구에서는 정보 이용자들이 필요로 하는 정보를 제공할 수 있는 Traceability System을 이용하는 데에 유용한 자료를 도출하기 위한 목적으로 현재 Traceability System을 이용해본 경험이 있거나 이용하고 있는 정보이용자를 대상으로 Traceability System을 조직에 새로운 기술혁신의 관점으로 인식하고 Traceability System의 이용에 영향을 미치는 핵심 요인들을 실증분석하였다.

Requirements traceability is regarded as one of the important quality attributes in software requirements engineering field. If requirements traceability is guaranteed then we can trace the requirements' life throughout all the phases, from the customers' needs in the early stage of the project to requirements specification, deployment, and maintenance phase. This includes not only tracking the development artifacts that accompany the requirements, but also tracking backwards from the development artifacts to the initial customer requirements associated with them. In this paper, especially, we dealt with the traceability between functional requirements and non-functional requirements. Among many Information Retrieval (IR) techniques, we decided to utilize Latent Semantic Indexing (LSI) and Latent Dirichlet Allocation (LDA) in our research. Ultimately, we conducted an experiment on constructing traceability by using two techniques and analyzed the experiment results. And then we provided a comparative study between two IR techniques in constructing traceability between functional requirements and non-functional requirements.
