AIS(Automatic Identification System) provides navigational information including identification, position, a ship's course and status to ground and other vessels. To obtain AIS Marine Equipment Approval Service, various requirements are required and meet the requirements International Standards. However, most of the requirements are to identify essential functions, response time, hardware requirements, and communication protocols of AIS. The requirements for the quality of SW are not sufficient or detailed, and the weight is relatively low. As role of SW grows and types become more diverse, AIS SW quality inspection is essential. In this paper, We apply eight-quality characteristics of ISO/IEC 25023 standard to improve SW coverage quality of AIS. Suggest additional AIS SW requirements based on the eight quality characteristics of ISO/IEC 25023 standard.

기존에 위험기반 테스팅(Risk-based Testing) 방법은 널리 알려져 있다. 또한 가치기반의 소프트웨어 공학(Value-based SW engineering)이 고전적인 방법론과 더불어 대두되고 있다. 요구공학을 기반으로 하면서 소프트웨어의 생산절차를 가치(Value)를 기반으로 구성하고 있다. 본 논문에서는 위험기반 테스팅 기법을 Value-based Testing과 접목하여, 테스트케이스에 우선순위를 부여하고, 우선순위별로 적절한 테스트 기법을 도출, 적용하여 그 효과를 검증하고자 한다. 검증의 방법은 적용 전/후의 품질비용을 기준으로 한다.

Reusing software components without proper analysis is very risky because software components can be used differently from the way that they were developed. This paper describes a new testing approach for reusing software components. With this new approach, it is possible to automatically decide if software components can be reused without retesting. In addition, when retesting is required for reusing software, test cases are generated more efficiently using the previous testing history.

In this paper, we propose the standard architecture for the IFF interface SW in naval combat management system(CMS). The proposed standard interface architecture is a method designed to reduce modification efforts and man-month of reliability test for the existing the IFF interface SW of 11 types. We identified highly dependent CMS and GFE information, leading to the redefinition of standard requirements and functions, and proceeded with the initial design applying the Naval Shield Component Platform(NSCP). Subsequently, using the Feature Model, we derived additional common and variable elements for the interface of multiple CMS and GFE. Considering the S.O.L.I.D principles, we designed the final architecture. The proposed IFF Interface SW, based on the standard architecture, is expected to enhance management efficiency through a common architecture, increase code reusability and scalability, and reduce development costs by shortening reliability testing times.

In this paper, we propose a new framework for detecting the unauthorized dumping of garbage in real-world surveillance camera. Although several action/behavior recognition methods have been investigated, these studies are hardly applicable to real-world scenarios because they are mainly focused on well-refined datasets. Because the dumping actions in the real-world take a variety of forms, building a new method to disclose the actions instead of exploiting previous approaches is a better strategy. We detected the dumping action by the change in relation between a person and the object being held by them. To find the person-held object of indefinite form, we used a background subtraction algorithm and human joint estimation. The person-held object was then tracked and the relation model between the joints and objects was built. Finally, the dumping action was detected through the voting-based decision module. In the experiments, we show the effectiveness of the proposed method by testing on real-world videos containing various dumping actions. In addition, the proposed framework is implemented in a real-time monitoring system through a fast online algorithm.

공공부분 S/W사업은 분리발주가 원칙이고 일괄발주가 예외지만 현재 많은 공공부분 S/W사업은 일괄 발주 사업으로 진행되고 있다. 일괄발주는 SI업체가 S/W업체도 선택하여 입찰 및 개발하기 때문에 발주자가 원하는 품질 좋은 S/W를 선택할 수 없고, 발주자가 S/W를 업그레이드 및 확장할 때 SI업체에 의존하게 되는 단점이 있다. 이런 단점을 보완하고, S/W분리발주를 활성화시키기 위해 지식경제부(구 정보통신부)에서는 S/W분리발주 매뉴얼을 작성하여 보급 및 교육을 하고 있으며, 발주처에서는 품질이 우수한 S/W를 선택하기 위한 S/W분리발주 BMT를 공인된 시험기관인 한국정보통신기술협회(TTA) SW 시험인증센터에서 BMT를 실시하고 있다. 본 논문은 위협관리시스템(TMS) S/W분리발주 BMT를 공인된 국가 시험인증기관인 한국정보통신기술협회(TTA) SW시험인증센터에서 수행한 사례를 기술하였다

Under the influence of the Fourth Industrial Revolution, there is a emphasis on capacity building based on computational thinking to foster talent for future. In Korea, SW education has been mandatory since 2018. Since 2017, research has been conducted on the definition of SW education capability and the development of diagnostic tools. At this time, the diagnostic tool for middle school has been revised and supplemented once in 2018 and is used so far. In response to the request from the field to expand the information diagnostic test for middle school to elementary school and high school, it began as one of the 2019 study on the effectiveness of SW leading schools. In this study, we develop a diagnostic tool for elementary and high school based on the diagnostic tool for middle school. Expert validity verification and preliminary inspections are carried out. Preliminary examinations will analyze the reliability, discrimination, and difficulty of the questions, and look forward to seeing the potential as a testing tool in the future.

The issue of method of software testing process implementation has recently been in the spotlight in korea and some vendor make every effort to improve the software testing process through the evaluation of TMMi. The level of software process is at initial level, nevertheless, so the high quality of software is not guaranteed. This paper apply to the TMMi Level2 Assessment criteria of Automobile control software testing process. The test policy and strategy, test planning, test monitoring and control, test design and execution, test environment goal. The result need to emerge development process connection on the test policy and strategy process, test planning process etc. Also, the study analyzed the infra structure to reach the repeated level via key process area. As the result the process implementation in organization suggests the policy development and the implementation activity. Finally, the practical can refer to this paper in order to implementation the software testing process.

This study compared and analyzed the results of proficiency testing between testers based on the international standard ISO/IEC 17043 proficiency testing requirements using ISO/IEC 25023 software quality characteristics evaluation. Application of the test was submitted to the KASTO as a software test in the electric test field defined by KOLAS. Among ISO/IEC 25023, the evaluation items for proficiency testing between testers were selected as functional completeness and time behavior. The comparison test between testers was carried out on May 28, 2019 at the accredited LG Electronics SW Laboratory in Seoul and attended by KOLAS assessors. The test evaluation method was measured once per tester with functional completeness, and measurement was repeated 10 times per tester according to time behavior. As a result, in the case of functional completeness, all 12 test steps were passed, and the satisfaction was evaluated. Time behavior was repeated 10 times, and the mean was 9.45 ± 0.01 seconds for testers 1 and 3 and 9.52 ± 0.0 seconds for tester 2, but there was no statistically significant difference. In conclusion, the proficiency of the testers was equal, and the reliability of the test results of the test institute was confirmed.
