국방 무기체계 신뢰성 향상을 위한 체계개발프로세스 개선방향 연구
최인규,김효중,임다훈,김영현,홍성돈,박재훈,성시일,김성준 한국신뢰성학회 2025 신뢰성응용연구 Vol.25 No.2
Purpose: This study aims to propose improvement measures for the development process of South Korea's defense weapon systems to enhance their reliability. It analyzes the current reliability management system and identifies areas for enhancement by benchmarking it against advanced international practices in both civil industries and foreign military organizations. Methods: The study establishes an analytical framework based on the IEC 60300 standard to systematically assess the current reliability management activities of South Korea's military. It then investigates advanced reliability management processes in leading industries and foreign military organizations. By comparatively analyzing these cases against South Korea's current system, the study identifies opportunities for improvement and proposes tailored enhancement strategies for the nation's specific defense context. Results: The analysis reveals that while South Korea possesses a foundational framework for reliability management, several key areas require improvement. Critical challenges identified include a lack of objectivity in reliability goal-setting, insufficient independence in Verification and Validation (V&V) processes, and difficulties in sharing reliability technology and data across organizations. These issues create data silos that impede integrated lifecycle management and limit the effectiveness of comprehensive reliability testing. Conclusion: This study recommends reinforcing the V&V process with greater independence to ensure objectivity. It also suggests advancing specialized reliability applications, such as the Accelerated Stress Test and Reliability Prediction (ASRP). Furthermore, establishing an integrated reliability information management system is critical to break down data silos. Ultimately, fostering closer collaboration among military, civilian, and academic sectors is essential for building a robust reliability ecosystem.

가열면상 의 단일액적 의 천이비등영역 에서의 열전달 에 대한 연구
최인규,남궁규완,이동진 대한기계학회 1984 대한기계학회논문집 Vol.8 No.1
The transition boiling of a liquid droplet on a heated flat surface was studied utilizing Kotake's model with the effects of viscosity of a thin vapor layer between the droplet and the hot plate taken into account. This problem was analyzed considering the process of the droplet evaporation which resulted in hydrodynamic instability at the liquid-vapor interface. The results of the study are as follows; (1)The effect of the viscosity in the vapor layer at the interface appears as a dimensionless number N, namely .sigma. .delta.$_{0}$ /.rho.nu.$^{2}$ (2)The time required for evaporation at the transitional region increases with the temperature difference ratio .DELTA. T$_{r}$. The rate of increase of the total evaporation time becomes larger as increasing of N$_{m}$(N number at maximum heat flux) increases.s.

우리나라의 대학 학부 공학계 교육(이하공학교육이라 약칭한다. )은 1970 년대부터 양적으로 크게 팽창하였고 우수교수의 유치 및 다액의 실험기기의 도입등에 힘입어 질적으로도 크게 개선되 었다. 그러나 현시점을 기준으로 하여 고려할 때에 현재는 현재대로 여러가지 문제점을 안고 있는 것이 사실이다. 그러므로 이러한 점에 대하여 검토를 하고 대책을 고려해 두는 것도 의의가 있는 일이라 생각된다. 그러나 여기서 이러한 모든 문제에 대하여 논하기는 어려우므로 분문 이러한 고려에서 대상밖이라 취급되기 쉬운 문제에 대하여 검토하고 사견을 말하기로 한다.
