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.

In the field of traceability systems, researchers focus on applications in the agricultural food traceability and scanning commodities. The purposes of this paper, however, is to propose an efficient and reliable traceability system that can be applied to all kinds of commodities. Currently, most traceability systems store data in a central server, which is unreliable when the system is under attack or if the administrator tampers with the data for personal interests. Therefore, it is necessary to design a system that can eliminate these threats. In this paper, we propose a decentralized and non-reversible traceability system for storing commodity data. This system depends on blockchain technology, which organizes data in the form of chains without a central server. This chain-style storage mechanism can prevent malicious modifications. In addition, some strategies are adopted to reduce the storage pressure and response time when the system has stored all kinds of commodity data.

Traceability has been held as an important factor in testing activities as well as model-driven development. Vertical traceability affords us opportunities to improve manageability from models and test cases to a code in testing and debugging phase. This paper represents a vertical test method which connects a system test level and an integration test level in testing stage by using UML. An experiment how traceability works to effectively focus on error spots has been included by using concrete examples of tracing from models to the code.

추적성은 소프트웨어 개발자에게 소프트웨어 산출물에 대한 변경을 추적하게 해 준다. 소프트웨어 제품 라인 개발에 있어서의 추적성은 공통성과 가변성을 고려해야 하기 때문에, 개별 제품에서의 추적성보다 복잡하다. 과거 연구에서 제품 라인 개발에서의 제품 피처와 요구사항 간의 추적성 구축을 제시되었다. 그러나 요구사항과 아키텍처 설계 사이의 추적성 구축은 다 대 다 관계와 아키텍처 계층으로 인해 고려해야 할 요소가 더 많다. 본 논문은 이러한 요소들을 고려하여, 제품 라인 개발에서의 요구사항과 아키텍처 사이의 추적성을 모델링하는 체계적인 방법을 제공한다. 또한 사례연구를 통하여 이 방법이 효과적임을 보인다.

추적성 개념은 모델 중심의 개발에서만이 아니라 테스트를 위하여 매우 중요한 요소이다. 어떤 기능을 중심으로 높은 추상수준에서부터 낮은 수준의 프로그램까지 수직적인 추적은 모델로부터 테스트와 디버깅 단계에 이르기까지 시스템을 잘 관리할 수 있게 한다. 또한 테스트 단계에서 발견한 결함에 대한 오류를 추적할 때 발생하는 단계별 추상 수준의 분리를 추적가능성으로 극복하게 한다. 이 논문에서는 XML을 기반으로 모델과 시험사례 그리고 소스코드를 수직적으로 추적하여 더욱 엄격한 테스트가 되는 방법을 제안한다. 실험을 통하여 추적이란 개념이 어떻게 작동하고 오류 부분을 찾아내는지 보이며 구체적인 사례를 이용하여 방법을 소개한다.

Environmentally friendly agricultural products(EFAPs) are on an increasing trend of supply, but not much enhancing the rate of consumption due to higher premiums and consumers' safety concerns. In order to enlarge the consumption of EFAPs and secure the income of the producing farmers, wholesale market should increase the treating amount of EFAPs and introduce traceability system for satisfying consumers' safety concerns. The purpose of this study is to present strategies of traceability system in wholesale market for environmentally friendly agricultural products. For this purpose, current traceability systems that are introduced and managed by government and private association are examined. For the successful management of the EFAPs' traceability system in wholesale market, the trading system, the functions of wholesale market, the level of consumers' safety concerns, and the managing costs should be considered.

This study developed the traceability information for tracing fishery products from the production step to the consumption step in the distribution channel of fishery products. Based on it, we further presented the theoretical linkage between traceability information and perceived qualities of internet shopping malls, and then investigated how traceability information affected trust and perceived usefulness in the internet shopping mall to find the key success factors of internet shopping malls of fishery products. We collected 194 responses from internet consumers who had prior experience on purchasing fishery products. This survey data was used to empirically test the ten research model hypotheses by using PLS. The PLS results indicated that traceability information had significant impact on trust and perceived usefulness. Finally, trust, perceived usefulness and perceived ease of use were found to be related to online consumers' intention to purchase fishery products.

Recently, a railroad system has a big and complicated structure of specification. Therefore, traceability between specification need to be identified for design change management and this is many engineer's concerns. Traceability means technical relationship. This is to trace other specification or component connect with relevant problem in case some problem should be examined. Traceability between functional specification can be proved through functional analysis essentially. This study will introduce an application method of functional analysis in the case of practical use project of MAGLEV train. And we propose the guide to identify traceability between function through functional analysis.

The purpose of this study was to derive practical improvement measures for the food traceability system that could improve food reliability and secure food safety. To this, in our survey May-June, 2019, 567 adult males and females were analyzed for recognition and experience of the food traceability system, measures to improve the system, and intention to make additional payments to improve the system. In the case of a food safety accident, 2.54 of 5 points were given on if the food was recalled or not. Approximately 77.4 percent of the respondents had never seen indication of a food traceability system, and approximately 93.8 percent had no access to, or experience with, using the system. Most respondents said that the food traceability system should be applied to items that need to be applied. As the volume of data that is recorded and managed by the government is recognized as high, improvement is needed. Finally, it was analyzed that the company intends to pay an additional 1.34% on average to expand its food traceability system. A more sophisticated cost analysis is needed to apply the improvements proposed to complement the plans that are acceptable to consumers and the industry.

추적이란 개념은 모델 중심의 개발에서만이 아니라 테스트를 위하여 매우 중요한 요소이다. 수직적인 추적은 모델로부터 테스트와 디버깅 단계에 이르기까지 시스템을 잘 관리할 수 있게 한다. 또한 테스트 단계에서 발견한 결함에 대한 오류를 추적할 때 발생하는 추상 수준의 오르내림을 추적가능성으로 극복하게 한다. 이 논문에서는 시스템 테스트 수준과 통합 테스트 수준에서 UML을 이용하여 수직적으로 연결하여 더욱 엄격한 테스트가 되는 방법을 제안한다. 실험을 통하여 추적이란 개념이 어떻게 작동하며 오류 부분을 찾아내는지 얼마나 효과적인지 보이며 모델에서 코드까지의 구체적인 사례를 이용하여 방법을 소개한다.
