In recent years, the functions added ta an embedded system have grown various and complex in most parts of the applications. Embedded software comes to include more functions and is getting bigger. Therefore it is getting difficult for software developers to keep the development time to market on time. This leads to a need for adequate design and test technique for embedded software. In this paper, we propose a software architecture style for embedded software. It facilitates the composition of reusable functions and helps developers reduce development time. We also propose a test method and tools for embedded software running on target systems.

무기체계 개발에 있어서 내장형 소프트웨어의 비중과 그 중요도가 점점 증가하고 있고, 고객 또한 무기체계 소프트웨어 개발 및 관리지침을 제정하여 소프트웨어 신뢰성 시험수준에 대한 놓은 요구사항을 제시하고 있다. 이렇게 대내외 환경이 변화하고 있음에 따라 당사는 고품질의 소프트웨어를 고객에게 납품하기 위해서 내장형 소프트웨어 신뢰성 향상활동을 수년간 수행해오고 있다. 업체주관 개발사업 증가와 무기체계 외주개발 비중 증가에 따라 고품질의 협력개발 소프트웨어의 획득이 중요해지고 있다. 하지만, 납품 받은 소프트웨어를 체계 통합하는 시기에 소프트웨어 결함이 많이 내재되어 있어 문제점이 많이 발생되고 있으며, 납품 이후에도 많은 결함수정과 재 작업이 발생하여 추가비용이 많이 발생하고 있다. 본 논문에서는 협력개발 소프트웨어 제품의 신뢰성 향상을 위해 TMMi 시험 프로세스를 적용하여 협력회사의 소프트웨어 시험 역량을 강화하고 고품질의 소프트웨어를 획득할 수 있는 방안을 제안하고자 한다.

보안 S/W의 보안성 평가기준(CC; Common Criteria)은 국제 표준 ISO/IEC 15408로 제정되었고, 시제품에 대한 보안기능요구사항과 보증요구사항을 표준화된 방법으로 표현하고 있다. 보안 S/W의 보안성은 중요하나 그 품질 또한 간과되어서는 안 된다. 이에, 본 논문에서는 CC에서 기술하고 있는 보안기능에 대한 S/W 품질평가기준에 대해 연구하였다.

Test effort estimated so far is as a by-product of the development effort estimation activity which is based on the FP, UCP, COCOMO model, or calculated data from the project knowledge base which is containing test effort information for the test phase on software development life cycle. In this paper, test effort estimation model and calculating procedures are suggested, which is independent from software development effort estimation model. Generally test efforts is depends on the number and the complexity of test cases, and also maturity of test organization that performs test activities, such as integration test, system test, acceptance test and so on. The estimated results with the suggested test effort estimation model has deviation of 4.7% compare to the corresponding test efforts generated by the development effort estimationprocedures. The suggesting model will be accurate more and more with refinements of coefficients which reflect the technical and environmental maturity level of test organization, and also including the software complexity level of projects.

This study proposed a method for determining weights for the eight quality characteristics, such as functionality, reliability, usability, maintainability, portability, efficiency, security, and interoperability, which are suggested by international standards, focusing on software test reports. Currently, the test results for software quality evaluation apply the same weight to 8 quality characteristics to obtain the arithmetic average. Weights for 8 quality characteristics were applied using the results from text analysis, and weights were applied using the results of text analysis of test reports for two products. It was confirmed that the average of test reports according to the weighted quality characteristics was more efficient.

이 연구에서는 서로 다른 사용자 인터페이스의 대화 방식에 따라 PC통신 소프트웨어 의 사용편이성이 어떻게 달라지는가를 살펴보고자 한다. 이를 위해 현재 국내에서 이 용되고있는 3개의 PC통신소프트웨어를 대상으로 남녀대학생 18명에 의한 사용편이성 평가 시험을 실시하였다. 시험은 강사에 의한 1:1 방식에 의해 실시하였다. 평가척도로 는 학습소요시간, 시험소요시간, 정답률을 이용하였다. 실험결과, 윈도우환경에서 구현 되는 메뉴, 아이콘, 명령어를 혼합한 대화방식의 소프트웨어보다도 도스환경에서 구현된 명령어 대화방식의 소프트웨어가 학습용이성 측면에서의 사용편이성이 높을 수 있다는 점이 시사되었다.

코로나19 대유행으로 비대면 교육이 보편화되어 온라인 학습과 시험이 교육기관에서 일반화되고 있다. 이러한 급격한 변화로 교육의 공정성 문제와 온라인 시험의 부정행위 문제가 대두되고 있다. 온라인 시험은 대면 시험과는 달리 시험 감독관이 부정행위를 적발하기 어렵기 때문에 응시자의 다양한 환경을 고려하여 정확하게 부정행위를 판별하는 방법이 필요하다. 본 연구에서는 온라인 시험환경에서 응시자의 행동 데이터와 영상데이터를 분석하여 부정행위를 감독관에게 추천하는 시스템을 제안한다. 제안 시스템의 구현을 통해 온라인 시험 환경에서 부정행위를 탐지 기능을 확인한다.

IEEE1394 standard supports both isochronous and asynchronous data transmission, thus enabling high-speed data exchange between PC and networked home electronic devices. This paper describes an implementation of Test Bed for Linux based IEEE1394 communication test. In this paper, An integrated Software was developed to test IEEE1394 communication environment. To develop the software, open source software(gscanbus,dvgrab, playdv, Xine, Kino) for the Linux environment was investigated and integrated. It was tested such as the communication among the devices, asynchronous date transmission, isochronous data transmission, and its result was successful. This integrated software has the potential to become efficient test tool for the futher development of networked home electronic devices and multimedia services.

Nowadays, due to the rapidly increasing number of package software products, quality test has been emphasized for package software products. When testing software products, one of the most important factors is to select metrics which form the bases for tests. In this paper, the types of package software are represented as characteristic vectors having probabilistic relationships with metrics. The characteristic vectors could be regarded as indicators of software type. To assign the metrics for each software type, the past test metrics are collected and analyzed. Using Bayesian belief network, the dependency relationship network of the characteristic vectors and metrics is constructed. The dependency relationship network is then used to find the proper metrics for the test of new package software products.

The system test was accomplished in delivery time for a suitable of various requirements at the software market. Especially, critical faults must be detected and removed for a close main functions and users against target system. In generally, proposed test methods are executed with a calendar time, not a competitive and effectiveness method as selective software testing. These methods are inapplicable to short term test or early system development stage. Moreover, it's accompanied by heavy cost. Overcoming of these problems, must attempted to new software test method role of core function in the system test. Selective software testing method is decided to mixing with the three-information such as a frequency, complexity of use scenario and fault impact. Using this information, searching a fatal error and usefully system test for an executed test scenario. In this paper, we have proposed new test method and verified testing results for the detection of critical faults or search a fatal errors with a system main function.
