        Since the National R&D Innovation Act was enacted in 2022, it became a crucial issue how to qualify or improve R&D activities and disseminate their outcomes. Many organizations have referred to various quality management standards such as the American National Standards Institute/American Society for Quality (ANSI/ASQ) Z1.13, International Organization for Standardization (ISO) 9001, and the American Society of Mechanical Engineers Nuclear Quality Assurance-1 (ASME NQA-1), as a means to set up their own quality system. ISO is the international standard for implementing a quality management system (QMS), which provides a framework and principles for managing an organization’s QMS, with the aim of ensuring that the organization consistently provide products or services that meet regulatory requirements. ISO 9001 can cover all aspects of an organization’s operations, and it can also be expanded to include R&D areas. The introduction of ISO 9001 to R&D aims to improve R&D practices and establish a standardized process framework for conducting R&D. ANSI/ASQ Z1.13 provides quality guidelines for research and consists of 10 sections covering various aspects of research quality, emphasizing ethical conduct, clear objectives, reliable data collection, and analysis. ASME NQA-1 is one of quality assurance standards for nuclear facility applications, but it has been extended and applied to R&D activities in the nuclear fields. It just focuses on planning, procedures, documentation, competence, equipment, and material control. KINAC has conducted extensive research on verifying and regulating nuclear activities while providing support for national nonproliferation technologies and policies. In addition to the quantitative growth achieved so far, efforts are being made to establish a qualitative and integrated management system. As a first step to achieve this goal, this study reviewed international standards and methodologies for research quality and derived the key components for R&D quality management. Moreover, the appropriate outline of quality management system framework was proposed for R&D as a regulatory support process, based on the ISO 9001. The implementation of quality management standards and procedures for R&D in KINAC, which could lead to improved research practices, more reliable data collection and analysis and increased efficiency in conducting R&D activities.

        The purpose of this study is to improve practical skill evaluation method of mushroom - trained certified technician's practical skill evaluation which is one of national qualification tests based on national incompetency standards. One of the current National Competency Standards (NCS), mushroom - trained certified technician uses NCS based practical assessment method. In order to improve the current practical evaluation method, we try to improve practical evaluation method based on field customized problem solving ability and improve the practical evaluation method, various evaluation methods should be constructed. On the purpose of identify the diversity and problems of the evaluation method, the experts of the group consultation, the mushroom-related research institute and the related industry collaborated to identify the problems of the actual mushroom - trained certified technician practicum test, This study on the evaluation improvement method was carried out. In this study, the contents of practical test of the current mushroom traits were analyzed and the trends of the latest mushroom industry were widely reflected.

        Antioxidants partially ameliorated the detrimental effects of reactive oxygen species (ROS) on sperm characteristics during in vitro storage. The objective of the present study was to investigate the single or synergetic antioxidative effect of curcumin and Vit. E on the characteristics of fresh boar sperm during in vitro storage. The sperm viability in curcumin, Vit. E supplementation and curcumin+Vit. E+H2O2 groups remained over 85.0% in 3 hr incubation period, but in 6 hr incubation period, curcumin+Vit. E+H2O2 groups was sharply dropped than those of curcumin and Vit. E group. The membrane intergrity in all evaluated groups except for H2O2 group did not significantly difference in 3 hr incubation period. The viability in curcumin or Vit. E supplementation were significantly increased than in curcumin+H2O2 and Vit. E+H2O2 group in 6 hr incubation period. The percentage of mitochondrial activity and acrosome intergrity obtained similar trends within same incubation periods irrespective of treatment. The lipid peroxidation of spermatozoal plasma membrane ranged from 11.6∼17.5 nM/l×106 and 14.0∼ 19.0 nM/l×106 in 3 hr and 6 hr incubation periods. In conclusion, curcumin or Vit. E rpplementation alone or cooperatively improved sperm viability index (motility, membrane intergrity, viability and survival rates) and fertility index (mitochondria activity, acrosome intergrity and lipid peroxidation) of fresh boar sperm, indicating that curcumin and Vit. E have a antioxidative properties through its scavenging activity against hydrogen peroxide.

        본 연구에서는 SC-PDSI를 이용하여 잠재증발산량 산정 방법이 가뭄지수 산정 결과에 미치는 영향을 평가하였다. 잠재증발산량 산정 방법으로 월열지수법, Penman-Monteith 방법, Hargreaves 공식 등 세 가지 방법을 이용하였으며, 기상청 56개 지점을 대상으로 세 가지 잠재증발산량 산정 방법에 따른 SC-PDSI를 산정하고 그 결과를 비교하였다. 분석 결과, Penman-Monteith 방법에 의한 결과와 Hargreaves 공식에 의한 결과는 월별로 큰 차이 없이 유사한 가뭄지수 산정 결과를 나타내고 있음을 확인하였으며, 월열지수법에 의한 결과는 상대적으로 큰 차이를 보이고 있음을 알 수 있었다. 월별로는 봄철과 겨울철 기간에 대해 산정된 가뭄지수와 가뭄상황 판단 결과가 차이를 보이고 있음을 확인하였다. 결론적으로 우리 나라에서 PDSI를 산정하고자 할 경우에는 Penman-Monteith 방법이나 Hargreaves 공식을 이용하는 것이 바람직할 것으로 판단된다.
