To successfully carry out large scale research projects while su, pp.rting quality assurance of research output, effective and systematic management through utilization of resources such as manpower, time and cost as well as engineering techniques such as component technology and design methodology is required. It is necessary to establish development methodology to su, pp.rt quality assurance. The development methodology covers the contents and procedures of the project, such as division of the project into independently executable units, allocation of resources including researchers, component technology, related know-how and equipment, deployment of research units and integration of the project at the end. In this paper we present systematic development methodology for quality assurance in large scale software development projects by analyzing the contents of the methodology a, pp.ied to the Gigabit Information-processing And Networking Technology development project(GIALT).

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.

e-navigation은 IMO에서 시작된 전략으로, 2018년부터 본격적으로 전략 이행을 하는 것을 목표로 하고 있다. 이를 위하여 e-navigation의 구현 및 개발을 위한 소프트웨어 품질보증 및 인간중심 설계 가이드라인의 개발이 진행되어 왔다. 2015년 6월, 이 가이드라인은 IMO MSC 95차 위원회에서 승인 후 회람문서로 등재되었다. 이 가이드라인의 실질적인 적용을 위해 본 논문에서는 소프트웨어 품질 보증과 인간중심설계에 공통으로 적용되는 사용성 평가 관점의 국제 표준에 대해 조사하고 분석하였다. 이 결과는 하드웨어와 소프트웨어가 결합된 e-navigation 장비의 개발을 위한 실무 적용 지침에 반영될 계획이다.

군에서 사용하는 무기체계의 경우 경제적이고 효율적인 조달·관리 및 유지를 위하여 국방규격을 제정하여 관리한다. 국방규격은 제품 및 용역에 대한 기술적인 요구사항과 요구필요조건의 일치성 여부를 판단하기 위한 절차와 방법을 서술한 문서로, 작성된 국방규격은 무기체계의 생산, 품질보증, 형상관리 등에 활용된다. 소프트웨어도 국방규격의 하나로 다른 국방규격(국방규격서, 품질보증요구서, 도면, 부품/BOM 목록)과 같이 작성되고 관리되나, 소프트웨어의 일부(또는 전부)를 포함하지 않고 규격화를 수행하는 경우가 있다. 이 경우 개발업체를 제외하고는 다른 업체들은 제품을 생산할 수 없어 경쟁계약이 제약될 뿐만 아니라, 승인 없이 업체가 임의로 소프트웨어를 변경할 수 있어 무기체계의 품질에도 큰 영향을 미친다. 따라서 소프트웨어의 규격화 누락 여부의 검증은 반드시 필요하나, 하드웨어 내부에 탑재되는 펌웨어의 경우 개발업체 외에는 규격화 누락 여부의 확인이 매우 어렵다. 본 연구에서는 실제 품질보증 업무 수행 시에 활용할 수 있는 소프트웨어 규격화 누락 여부의 검증 방안을 제시하였으며, 이를 통해 무기체계의 효율적인 생산, 품질보증에 기여할 것이다.

In software engineering, to ensure reliability between systems, describing both system architecture and assurance arguments between system elements is considered necessary. There are proposals for system architecture assurance, but use of these traditional methods often requires development of different diagrams using different editors. Because the visual sense of the traditional methods is inadequate, errors readily occur when manipulating different diagrams. Therefore, it is essential that the assurance of dependability between components and systems is visualized and easy to understand. In this paper, an integrated approach to describe the relationship between system actors and system architecture is proposed, and this approach is clarified using an enterprise architecture modeling language. A case study is carried out and comparison to the traditional approach $d^*$ framework is explained. The comparison results show that the proposed approach is more suitable for ensuring dependability in system architecture.

One of the major issues in the material-based or acceptance quality characteristics asphalt pavement Quality Assurance (QA) is that the method does not have rationality to link between the individual materials and the projected performance of the pavement. A new asphalt mix QA method has been recently developed under a national research project using the probabilistic Performance Related Specification (PRS). This advanced PRS QA methodology integrates the AASHTOWare Pavement ME Design$^{(R)}$ technology with the simple performance test concept that bridges the material characteristics with the pavement performance. This paper presents a case study of asphalt pavement performance using the developed PRS QA computer program, named Quality Related Specification Software (QRSS), with an actual pavement project, to demonstrate the developed PRS procedure and to assess the robustness of QRSS in terms of the rationality of the distress predictions. The results of this limited case study show that the new PRS QA method reasonably predicts the pavement performance, properly applied the probabilistic methods, and produced rational pay adjustment.

The Common Criteria (CC) philosophy is to provide assurance based upon an evaluation of the IT product or system that is to be trusted. Evaluation has been the traditional means of providing assurance. It is essential that not only the customer' srequirements for software functionality should be satisfied but also the security requirements imposed on the software development should be effectively analyzed and implemented in contributing to the security objectives of customer's requirements. Unless suitable requirements are established at the start of the software development process, the re suiting end product, however well engineered, may not meet the objectives of its anticipated consumers. By the security evaluation, customer can sure about the quality of the products or sys tems they will buy and operate. In this paper, we propose a selection guide for If products by show ing relationship between security engineering and security evaluation and make help user and customer select appropriate products or system.
