'Commit-bug link', the link between commit history and bug reports, is used for software maintenance and defect prediction in bug tracking systems. Previous studies have shown that the links are automatically detected based on text similarity, time interval, and keyword. Existing approaches depend on the quality of commit history and could thus miss several links. In this paper, we proposed a technique to link commit and bug report using not only messages of commit history, but also the similarity of files in the commit history coupled with bug reports. The experimental results demonstrated the applicability of the suggested approach.

In this paper, we propose UniBAS(Unified Bug Analysis System) to provide a unified repository model by integrating the extracted data from the heterogeneous bug tracking systems. The UniBAS reduces the cost and complexity of the MSR(Mining Software Repositories) research process and enables the researchers to focus on their logics rather than the tedious and repeated works such as extracting repositories, processing data and building analysis models. Additionally, the system not only extracts the data but also automatically generates database tables, views and stored procedures which are required for the researchers to perform query-based analysis easily. It can also generate various types of exported files for utilizing external analysis tools or managing research data. A case study of detecting duplicate bug reports from the Firfox project of the Mozilla site has been performed based on the UniBAS in order to evaluate the usefulness of the system. The results of the experiments with various algorithms of natural language processing and flexible querying to the automatically extracted data also showed the effectiveness of the proposed system.

During the development of the software, a variety of bugs are reported. Several bug tracking systems, such as, Bugzilla, MantisBT, Trac, JIRA, are used to deal with reported bug information in many open source development projects. Bug reports in bug tracking system would be triaged to manage bugs and determine developer who is responsible for resolving the bug report. As the size of the software is increasingly growing and bug reports tend to be duplicated, bug triage becomes more and more complex and difficult. In this paper, we present an approach to assign bug reports to appropriate developers, which is a main part of bug triage task. At first, words which have been included the resolved bug reports are classified according to each developer. Second, words in newly bug reports are selected. After first and second steps, vectors whose items are the selected words are generated. At the third step, TF-IDF(Term frequency - Inverse document frequency) of the each selected words are computed, which is the weight value of each vector item. Finally, the developers are recommended based on the similarity between the developer's word vector and the vector of new bug report. We conducted an experiment on Eclipse JDT and CDT project to show the applicability of the proposed approach. We also compared the proposed approach with an existing study which is based on machine learning. The experimental results show that the proposed approach is superior to existing method.

Preference of stink bugs to various leguminous seeds was evaluated by using VTS (Video Tracking System) in laboratory. Major soybean stink bugs such as bean bug, Riptortus pedestris (Fabricius), one-banded stink bug, Piezodorus hybneri (Gmelin), eastern green stink bug, Nezara antennata (Scott), and sole bug, Dolycoris baccarum (L.) were significantly most attracted to Cheongjakong, a soybean variety, baited fish-net trap, followed by soybean varieties Ilpumgeomjeongkong and Taekwangkong, a peanut variety Daekwangdangkong, a kidney bean variety Gangnangkong, and a adzuki bean variety Jungwonpat, respectively in a soybean field. VTS observation in laboratory showed that R. pedestris and D. baccarum had significantly higher frequency of visit on Cheongjakong, followed by Ilpumgeomjeongkong. However, P. hybneri, N. antennata and Halyomorpha halys (Stal) had significantly higher number of visits on Cheongjakong, Seonnogkong and Jinpumkong, followed by Ilpumgeomjeongkong. The sojourned time of stink bugs, however, was significantly longer on Cheongjakong regardless of species of the bugs. Accordingly, Cheongjakong was evaluated as the most preferred soybean seed by fish-net trap and VTS. Thus, VTS is found to be an effective means to evaluate the food preference of stink bugs.

QA직군은 게임 제작 프로젝트의 초기 단계부터 게임의 품질관리를 위한 계획을 수립하고, 개발 단계에 맞춰 QA를 진행하는 과정에서 효율적인 업무 수행을 위해 전문적인 도구의 활용이 필요하다. 게임 QA에서 사용하는 결함관리도구 중 Redmine은 결함관리 뿐만 아니라 뉴스 기능으로 프로젝트 소식을 공유하고, 일감에서 결함을 관리하고, 위키를 통해 지식관리를 수행할 수 있다. 또한 애자일 플러그인을 설치하여 애자일 기반으로 프로젝트를 관리할 수 있다. 코로나19로 인해 비대면 업무 환겨에 대한 관심이 증대하면서 게임 QA도 적절한 온라인 도구를 활용하는 것이 바람직하다.

소프트웨어의 품질을 향상시키기 위해 결함을 찾고 시정하는 것을 통제하는데 가장 중요한 요소가 바로 오류/장애/실패(통칭하여 결함(defects)를 효과적으로 추적하는 것이며, 결함을 추적하기 위해서는 효과적인 결함 추적시스템(Defect Tracking System)의 도입이 필요하다. 기존의 결함 추적 시스템은 고객/사용자로부터의 문제보고, 테스팅 기간 중의 결함보고, 변경관리 기능 등을 통합적으로 제공하고 있지 못하다는 점과 테스팅을 포함한 개발과정의 정량적 통제를 위한 데이터를 효과적으로 축적 제공하지 못하고, 더욱이 결함의 근본적인 원인을 찾아 해결할 수 있도록 하기 위한 정보를 효과적으로 제공하지 못하고 있는 문제가 있다. 본 논문에서는 이러한 기존의 결함 추적 시스템의 문제점을 해결하고자 설계/구축되어 현재 사내에서 활용되고 있는 결함관리 시스템인 Promise System을 소개하고자 한다. Promise 시스템은 고객의 불만 및 요구사항, 인스펙션 및 테스팅 시의 결함 및 요구사항에 대하여 각 담당자별로 업무를 할당, 추적할 수 있게 하고, 결함 및 요구사항에 관한 각종 상태정보와 통계 정보를 제공하여, 각 개발 및 테스팅 단계별로 결함 제거 목표의 수립, 정량적 통제, 결함 원인 분석을 통한 프로세스 개선 등을 지원하는 시스템이다.

Korea Aerospace Research Institute takes part in the vibration control software development for an Active Vibration Control System (hereafter, AVCS) for helicopters with Korea Aerospace Industries Ltd. in the Light Civil Helicopter (LCH) Project. The vibration control software is being developed per RTCA/DO-178C certification regulation and use of configuration management tools for software outputs is required. Redmine, an open source software is for issue or bug tracking and management software. Git, another open source software is a distributed version control software and is developed for Linux OS development. This paper introduces the functionalities of Redmine and Git, the reason why they are selected for the configuration management tool for the software outputs, and how they are being used for AVCS software development.
