  • Background: This study aimed to prioritize policy measures to improve radiation safety management in medical institutions using the analytic hierarchy process. Materials and Methods: It adopted three policy options-engineering, education, and enforcement-to categorize safety management measures, the so-called Harvey's 3Es. Then, the radiation safety management measures obtained from the current system and other studies were organized into action plan categories. Using the derived model, this study surveyed 33 stakeholders of radiation safety management in medical institutions and analyzed the importance of each measure. Results and Discussion: As a result, these stakeholders generally identified enforcement as the most important factor for improving the safety management system. The study also found that radiation safety officers and medical physicists perceived different measures as important, indicating clear differences in opinions among stakeholders, especially in improving quality assurance in radiation therapy. Hence, the process of coordination and consensus is likely to be critical in improving the radiation safety management system. Conclusion: Stakeholders in the medical field consider enforcement as the most critical factor in improving their safety management systems. Specifically, the most crucial among the six specific action plans was the "reinforcement of the organization and workforce for safety management," with a relative importance of 25.7%.

  • Purpose: The purpose of this study is to assess the status of the Human research Protection Program (HRPP) within a hospital or a research institute in Korea. Methods: Survey was conducted during June 12th-21th 2019. Survey was distributed to the members of Korean Association of IRB (KAIRB) through each IRB office. Descriptive statistics were performed using SPSS ver. 26. Results: A total of 86 people responded, and 75 (87.0%) answered that they have perceived the HRPP. Seventy out of 86 respondents (81.4%) were conducting internal audit, several institutions were operated simultaneously the other form of audits such as IRB audit, system audit. Regarding the management of Suspected Unexpected Serious Adverse Reaction (SUSAR), 62.8% answered that they have regulation that can decide to suspend the study when there is a risk to subject safety. Among the respondents, 66.3% performed 'Help desk.' Conclusion: In this study, we assessed the current status of HRPP operation at each research institution based on Ministry of Food and Drug Safety (MFDS) HRPP guidelines. The HRPP accredited institution operated the subject protection activities according to this program, and even if the HRPP was not officially operated, the related activities were conducted focusing on the cases that could have a significant impact on the safety of research subjects. In order to ensure the quality of domestic clinical trials and to stably establish the HRPP, efforts at the individual institution level will be required.

  • 차대 보행자 교통사고는 발생빈도에 비하여 사망률이 매우 높은 특징이 있다. 전세계적으로 정부 및 보험사에서는 보행자 보호를 위한 새로운 안전기준을 수립 및 강화하는 추세이다. 보행자 보호 성능을 향상시키기 위하여 한국정부는 2007 년부터 신차안전도평가에서 보행자 안전을 평가하고 있다. 보행자 보호 성능은 점진적으로 향상되었으나 여전히 미흡한 상태이다. 전개형 후드 및 보행자 에어백 등으로 구성되어 있는 보행자 보호 시스템은 보행자 보호를 위한 대안이 될 수 있다. 보행자의 머리상해기준값을 감소시키기 위하여 새롭게 정의된 설계방법론을 바탕으로 보행자 에어백 설계 절차를 제안하였다. 제안된 설계방법론을 실용적인 측면에서 검토하였고 보행자 보호 시스템의 제작에 적용이 가능하다.

  • 미국선녀벌레 생물적 방제를 위한 기생성 천적인 선녀벌레집게벌 대량사육 체계를 구축하였다. 선녀벌레집게벌 고치 생산은 기주인 미국선녀벌레 약충밀도와 기주식물의 재식밀도에 따른 차이를 보였지만, 뽕나무 기주식물 잎당 평균 5~8개, 주당 평균 70~150개가 생산되었다. 선녀벌레집게벌 암컷 평균 고치 길이는 6.01~6.46 mm, 수컷은 4.20~4.62 mm로 암수 간 통계적으로 유의미한 차이를 보였으며, 우화 전 고치상태에서의 암수 구분으로 선녀벌레집게벌을 효과적으로 방사할 수 있을 것으로 보인다. 반야외조건에서 선녀벌레집게벌 기생률은 평균 13~17%로, 방사 마리수에 따른 기생률 차이는 확인되지 않았으나 방사 마리수가 많을수록 미국선녀벌레 개체군밀도증가율이 낮아지는 경향을 보였다. 선녀벌레집게벌의 성비나 이화성은 기주의 영기에 따라 달라졌다. 기주의 영기가 낮을수록 이화성 비율이 증가했고, 4~5령 약충에 기생시 암컷의 비율이 높게 나타나 대량사육 시 개체조절이 가능할 것으로 판단된다.
