Generally, in analysis of reliability of Design and Development Phase, reliability of electrical components is analyzed based on standards such as MIL-HDBK-217F, Bellcore Issue 4,5,6 by analyzing stress of architectural side (Power, Voltage, Current and quality level of components) of weapon system and stress of operational side (operational environment, operational temperature, Operational Profile). But the reliability of mechanical components is analyzed based on the data book of failure history of mechanical parts called NPRD-95(Nonelectronic Parts Reliability Data-95) without any analysis of above stress. However, even if it's the same mechanical parts, it might have different failure rate(fatigue, wear, corrosion) during operation depending on how weary(stress : pressure, vibration, temperature during operation) the parts are. Therefore, analyzing reliability using just data book can cause big difference in reliability instead of analyzing based upon stressfulness that parts might have, operational concept, and other various factors. Thus, This paper will guide the way of predicting reliability by organizing ways of predicting reliability for system organization and adopt ing NSWC-98/LE1(Naval Surface Warfare Center-98/LE1) for mechanical components.

Built-In-Test is a design feature in more and more advanced weapon system. During development test and evaluation(DT&E) it is critical that the BIT system be evaluated. The BIT system is an integral part of the weapon system and subsystem. Built-In-Test assists in conducting on system and subsystem failure detection and isolation to the Line Replaceable Unit(LRU). This capability reduces the need for highly skilled personnel and special test equipment at organizational level, and reduces maintenance down-time of system by shortening Total Corrective Maintenance Time. During DT&E of weapon system the objective of BIT system evaluation is to determine BIT capabilities achieved and to identify deficiencies in the BIT system. As a result corrective actions are implemented while the system is still in development. Through the use of the reiterative BIT evaluation the BIT system design was corrected, improved, or updated, as the BIT system matured.

현대 무기체계는 탐지센서, 레이더, 통신기기, 발사대 등과 같이 첨단 기술이 반영된 동일한 장비 여러 개(Multiple Systems)가 서로 연동하여 하나의 체계를 구성하는 범위로 확장되고 있으므로, 이러한 환경을 고려한 신뢰성 성장분석이 이루어 져야한다. 본 논문에서는 4개 모듈로 구성된 발사대를 분석대상으로 선정하였다. 분석은 RGA 소프트웨어를 활용하였으며, 사용된 시험데이터는 임의로 가정한 고장시간 및 고장이력 등을 활용하였다. 그리고 입력한 시험데이터 유형별로 적절한 모델 선정 및 분석방안을 제시하였고, 산출된 성장 그래프를 각각 도식화하여 결과를 비교하였다.

서양우,오영일,박은심,임성준,이승상 한국시스템엔지니어링학회 2019 시스템엔지니어링학술지 Vol.15 No.2

Although the weapon systems are becoming more diverse and complex, they are progressing in a short development period and a longer test and evaluation period. The more difficult the given environment is, the more efforts and performance of quantitative target values can be made by development agencies to carry out stable projects. However, these target values of the Integrated Logistics Support are not specified in the requirements and being set during the system development phase. In this paper, application of MOEs, MOPs and TPMs for ILS are presented and provided the basis for carrying out systematic Verification & Validation activities. As a result that MOEs of the ILS were chosen as Availability and MOPs as Mission Reliability, Logistics Reliability, Maintainability and Supportability and TPMs as MTBF, MTBCF, MTTR and so on. In particular, it is appropriate tailoring and apply the TPMs considering the cost, schedule, scope of work and characteristics of the project.

Purpose: To develop the reliability growth planning for a subsystem of guided weapon system using PM2-Continuous model. Methods: The target MTBF of the subsystem is set by allocating the system target MTBF to the lower level, where ARINC method is applied. Other model parameters such as initial MTBF, management strategy ratio and average fix effectiveness factor are chosen from historical growth parameter estimates. Given the values of model parameters, the reliability growth planning curve using PM2-Continuous model is constructed and the sensitivity analyses are performed for the changes of model parameters. Results: We have developed the reliability growth plan for a subsystem of guided weapon system using PM2-Continuous model. It was found that the smaller the ratio of initial MTBF to target MTBF, the smaller the management strategy ratio, the smaller the average fix effectiveness factor, and the shorter the development test period, the higher reliability growth is required. Conclusion: The result of this study will be used as a basis for establishing the reliability growth plan, the test period setting and the budget appropriation for the similar system entering the system development stage in the future.

Purpose: This study aimed to identify the relationships among death perceptions, death anxiety, and terminal care attitudes of nurses in oncology unit and to explore the predictors affecting their attitudes toward terminal care in Korea. Methods: A sample of 94 nurses was recruited from oncology units at one university hospital and a national medical center in Korea. The subjects completed a demographic questionnaire, the View of Life and Death Scale, the Fear of Death Scale the Korean version, and the Attitudes toward Nursing Care of the Dying Scale. Results: The subjects" terminal care attitudes were significantly positively influenced by death concern, perception of positive meanings of death, and experiences with the death of a family member or acquaintance in the last year. Those influential variables explained 21.5% of their terminal care attitudes. Conclusion: Findings of this study suggest that developing continuing education programs that teach effective coping strategies to prevent death anxiety and identifying barriers that can make caring for dying patients difficult may make a significant positive increase in the nurses’ attitudes toward care of the dying. In addition, the provision of effective palliative care in oncology settings remains open to review through further research and development.

이관영(Lee, Kwan-Young),김상문(Kim, Sang-Moon),박은심(Park, Eun-Shim),박재은(Park, Jae-Eun),김근형(Kim, Geun-Hyung) 한국산학기술학회 2014 한국산학기술학회논문지 Vol.15 No.9

무기체계에서의 소프트웨어에 대한 비중이 커짐에 따라, 소프트웨어 ILS(Integrated Logistics Support)에 대한 관심 이 커지고 있다. 그러나 기존 무기체계에서 ILS 개발은 하드웨어 중심으로 적용하고 있어 소프트웨어에 그대로 적용하기 힘든 실정이다. 본 논문은 소프트웨어 ILS의 실무 적용 어려움이 무엇인지 원인을 파악하고 문제점을 분석하기 위해 국내/외 규정 및 사례들을 통해 현 실태를 파악하였다. 또한, 소프트웨어의 유지보수 특성을 고려하여 소프트웨어와 하드웨어 ILS의 차이점을 검토하고, 소프트웨어 ILS 요소개발 범위 설정을 통해 국내에 적용이 가능한 소프트웨어 ILS 개발방안을 제안하였 다. 이는 소프트웨어 ILS 개발을 위한 구체적인 실무 적용방안을 수립하는 데 도움이 될 것으로 기대한다. The increasing importance of software has highlighted the need for the proper application of software ILS. On the other hand, the development of ILS has been somewhat limited to the area of hardware development. Therefore, this study examined the potential difficulties in applying software ILS to practical uses, and analyzed the drawbacks by reporting several domestic or foreign regulation cases. In addition, the differences between hardware and software ILS were examined by considering their characteristics of maintenance. Eventually, by establishing the proper range, this study proposes a development plan that is suitable for domestic weapon systems. The proposed research is expected to be helpful for offering specific plans for designing software ILS.
