군수품 최초양산품 품질관리는 연구개발 이후 최초로 양산 계약된 군수품을 대상으로 개발 후 완성된 규격에 따라 개발품의 양산 실현 가능성과 적합성 평가를 목적으로 수행한다. 하지만 본 연구를 통한 무기체계 최초양산품 소프트웨어 품질보증을 수행하기 이전까지 최초양산품 품질보증은 하드웨어 중심으로 수행되어 소프트웨어에 대한 품질보증은 미흡한 상태였다. 이로 인해 후속 양산단계에서 소프트웨어의 문제점들이 발견됐을 경우 불가피한 기술변경에 따라 많은 시간과 비용이 소요되었다. 본 논문에서는 소프트웨어 기술자료의 충분성 및 적합성을 점검하기 위한 무기체계 최초양산품 소프트웨어 품질보증 프로세스 연구를 수행한 결과를 보인다. 그 결과 컴퓨터 파일의 완전성 점검, 소프트웨어 기술문서의 적합성 점검, 소프트웨어 기술자료와 그 외 국방규격의 연계 여부를 점검하는 프로세스를 정립하고 이 프로세스를 적용하여 최초양산품 소프트웨어 품질보증을 수행한 결과를 분석하여 최초양산품 소프트웨어 품질보증 프로세스의 효용성을 보인다. 소프트웨어 기술자료의 완전성을 확보하여 양산단계에서 발생할 수 있는 소프트웨어 문제점을 사전에 식별하여 소프트웨어의 선제적인 품질 확보에 기여할 수 있음을 보인다.

As software projects become larger and more complex, we need to take a more systematic approach to quality assurance. One plausible approach is the use of SQA (software quality assurance) methodology. Since this SQA methodology was not available, our study presents a SQA methodology. This methodology has a repository in which a set of quality assurance tasks with their related techniques and deliverables is defined and from which one can select only appropriate tasks based upon characteristics of project. This study further suggests a rule-based approach for supporting task selection process.

The construction industry consists of various and massive architectural information as an architectural process includes a variety of design stages with cooperation of many disciplines. A Building Information Modeling (BIM) serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle from inception onward. building SMART has developed Industry Foundation Classes (IFC) standard for interoperability of BIM based information. Several software tools are already IFC-compliant. However, there are a lot of problems related to efficient interoperability of software owing to the lack of guide regarding the software usage and insufficiency IFC interfaces of software. The purpose of this study is to suggest efficient IFC support interface development methodologies of existing IFC certified software. The scope of this study is interoperability test for open BIM based quality assurance. To achieve this purpose, the authors have classified subject of open BIM based quality assurance and investigated IFC certification process and certified software. In addition, the authors have exported and imported via IFC files using different IFC interfaces in the software for interoperability of architectural objects and their properties. Finally, the authors have suggested IFC support interface development methodologies and hereafter direction for efficient interoperability of IFC certified software based on open BIM.

KASS(Korea Augmentation Satellite System)는 국토교통부에서 2014년부터 개발 중인 한국형 위성항법보강시스템이다. KASS는 항공기 안전에 영향을 미칠수 있는 항공용 시스템이기 때문에 KASS의 각 소프트웨어는 안전성 분석을 통해 할당된 DO-178B의 소프트웨어 레벨에 따라 개발이 수행된다. KASS의 하위시스템인 통합운영국의 경우 일부 소프트웨어를 제외하고는 DO-178B 레벨E를 할당 받았으며 DO-178B 레벨E 소프트웨어의 경우 제품 보증을 위해 ECSS-Q-ST-80C 카테고리 D를 준수하여 개발하도록 하고 있다. 본 논문에서는 ECSS-Q-ST-80C를 만족하기 위해 ECSS-E-ST-40C, ECSS-Q-HB-80-04A를 분석하여 KASS 통합운영국 소프트웨어의 제품 보증을 위한 소프트웨어 생명 주기 별 활동 및 소프트웨어 품질 모델, 메트릭을 제안한다.

This paper introduces Primetals Technologies' Through-Process Optimization (TPO) Services and Through-Process Quality Control (TPQC) System, which integrate domain knowledge, software, and automation expertise to assist steel producers in achieving operational excellence. TPQC collects high-resolution process and product data from the entire production route, providing visualizations and facilitating quality assurance. It also enables the application of artificial intelligence techniques to optimize processes, accelerate steel grade development, and enhance product quality. The main objective of TPO is to grow and digitize operational know-how, increase profitability, and better meet customer needs. The paper describes the contribution of these systems to achieving operational excellence, with a focus on quality assurance. Transparent and traceable production data is used for manual and automatic quality evaluation, resulting in product quality status and guiding the product disposition process. Deviation management is supported by rule-based and AI-based assistants, along with monitoring, alarming, and reporting functions ensuring early recognition of deviations. Embedded root cause proposals and their corrective and compensatory actions facilitate decision support to maintain product quality. Quality indicators and predictive quality models further enhance the efficiency of the quality assurance process. Utilizing the quality assurance software package, TPQC acts as a "one-truth" platform for product quality key players.

To achieve software quality and human-centred design for electronic ship navigation called e-navigation, an international guideline of software quality assurance and human-centred design was approved in 2015. Usability is a common goal of both software quality assurance and human-centred design as developing e-navigation system and software developments. Therefore, research is needed to evaluate the usability of e-navigation systems and software such as metrics that can use usability testing. This paper derives effectiveness metrics for e-Navigation usability testing based on international standards. The research method is to analyses and compares the effectiveness measurement and metrics in ISO 9241-11 for human-centered design and ISO/IEC 25022 and 25023 for software quality to find out measurements and metrics being defined commonly. The derived metrics are applied to Electronic Chart Display and Information System as a case study based on performance standard.

The purpose of this study is to evaluate the usefulness of a software-based quality assurance system based on Volumetric Modulated Arc Therapy treatment plan. Evaluate treatment plan through the D VH analysis, PTV mean dose ($D_{mean}$) and PTV 95% dose($D_{95}$) compare the MFX based on original treatment plan, Average error rate was $0.9{\pm}0.6%$, $1.0{\pm}0.8%$, respectively. Measuring point dose using phantom and ion chamber, the average error rate between the ionization chamber and MFX was $0.9{\pm}0.7%$, $1.1{\pm}0.7%$ (high dose region), $1.1{\pm}0.9%$, $1.2{\pm}0.7%$ (low dose region).

Purpose: Autonomous driving cars, which are often represent the new convergence product, have been researched since the early years of 1900 but their safety assurance policies are yet to be implemented for real world practices. The primary purpose of this paper is to propose a modular concept based on which a safety assurance system can be designed and implemented for operating autonomous driving cars. Methods: We combine a set of key attributes of CE mark (European Assurance standard), E-Mark (Automobile safety assurance system), and A-SPICE (Automobile software assurance standard) into a modular approach. Results: Autonomous vehicles are emphasizing software safety, but there is no integrated safety certification standard for products and software. As such, there is complexity in the product and software safety certification process during the development phase. Using the concept of module, we were able to come up with an integrated safety certification system of product and software for practical uses in the future. Conclusion: Through the modular concept, both international and domestic standards policy stakeholders are expected to consider a new structure that can help the autonomous driving industries expedite their commercialization for the technology advanced market in the era of Industry 4.0.
