지난 2021년 버진 오빗(Virgin Orbit)사는 747-400 항공기를 공중발사 플랫폼으로 개조하여 2월과 7월 두 차례 공중발사에 성공을 하였다. 기존 지상발사 대비 발사 장소나 날씨에 큰 구애를 받지 않고, 비용을 절감할 수 있으며, 발사 준비시간 단축과 고도 및 속도의 이득을 볼 수 있는 등 큰 효용성으로 인해 공중발사에 대한 관심이 증가하고 있다. 또한 전자장비의 소형/정밀화로 소형위성이 과거 중/대형 위성과 유사한 성능을 가지게 됨으로써 향후 소형위성 발사가 주를 이룰 것으로 전망된다. 본 논문에서는 국내 대형 민항기를 활용한 공중발사 플랫폼의 비행안전성 확보를 위해 국내 및 해외, 민간 및 군의 감항인증 규정/절차 등 제도적 인증 방안에 대해 살펴보고 적용 가능한 민간 및 군 감항인증 기술 기준을 검토 및 분석하였다. 그 결과로, 국내 현실을 반영한 감항인증 방안과 공중발사 플랫폼으로 개조 시 적용 가능한 감항인증 기술기준을 기반한 감항인증기준(안)을 결론에서 제시하고자 한다.

Purpose: As the concerns for the environment are gradually prioritized, increasing interests of environment-friendly buildings are drawn. The Green Standard for Energy & Environmental Design (G-SEED) has been strengthened. However, there are no specific assessment criteria that reflect the special situation of healthcare facility. UK, US and Japan have green building certifications specially designed to evaluate sustainable healthcare facilities. This study has been started in order to provide basic information for developing assessment criteria for healthcare facilities in Korean Green Standard for Energy and Environmental Design. Methods: In this study, we investigated three foreign green building certifications and compared their assessment system and criteria for healthcare buildings. Results: Each of the three foreign certification standards showed the difference in the system, but all contained the contents specific to healthcare facilities. Evaluation items were affected by regional cultural environment and also medical environment. Patient safety and integrative planning were the most important assessment contents. Implications: Based on this analysis, Korean Green Standard for Energy & Environmental Design for healthcare facilities will be developed.

This study analyzes the effects of personal lockers, drinking fountains, and all-in-one shutters (hereinafter referred to as "corridor walking obstacles") on evacuation safety to suggest the necessity of operating a more effective educational facility safety certification system. To achieve this purpose, the five-story high school building with the obstacles installed in the corridor has been chosen, and evacuation tests through the Pathfinder Simulation Program have been carried out. When the evacuation exit is designated in the current state, where the students are placed on the 2nd, 3rd, and 4th floors and the corridor walking obstacles are applied as a variable, the required safe egress time (RSET) is 322 seconds. This can lead to dangerous results in the event of a disaster by exceeding the available safe egress time (ASET) standard of 240 seconds by 82 seconds. When students are placed on the 1st, 2nd, and 3rd floors under the same conditions, the RSET is 214.5 seconds, 25.5 seconds lower than the ASET standard, indicating that it is effective in reducing the impact of walking obstacles on evacuation time. The safety management plan for walking obstacles in the corridors is discussed, considering the special characteristics of the school corridors. The results of this study can be used as the necessary data for optimizing evacuation routes in corridors and creating a safe, educational environment.

The present management of the domestic and international advanced enterprises is transferring the systems and the regulations to the prevention system management. Expecially, KOSHA (Korea Occupational Safety & Health Agency) in Korea has supported to set up the OSHMS (Occupational Safety & Health Management System) by KOSHA 18001 since 1997. But small & medium enterprises (SMS) has many difficulties to set up the OSHMS system because of limited natural and human resources. In this study, the rating system as a judgment method of an OSHMS based on the certification standard of the OSHMS was suggested for SMS to adopt voluntarily the OSHMS, certify KOSHA 18001, and improve the safety and health level.

System scaffolding and shoring are temporary structures in which vertical members, horizontal members, bracing members and trusses are assembled and installed. In order to ensure quality and safety, the quality test shall be carried out in accordance with the Guidelines for Quality Management of Construction Works (MOLIT Notice No. 2020-750). The quality test method (national standard) for Components for tied post system scaffolding and shoring is based on the Korean standards (KS F 8021) and the Safety certification standards (MOEL Notice No. 2021-22). However, the two standards differ in some aspects such as performance standards and etc, so cause confusion when applying them on-site. In addition, the standard for truss are applied only to trusses for shoring and cannot be applied to trusses for scaffolding. Therefore, this study aims to unify the two national standards and establish realistic standards.

Objectives: The purpose of this study is to provide comprehensive information of qualification systems of developed countries needed to establish our national system for QI(Quality improvement) specialists. Methods: All articles related to any applicable domestic or foreign countries' laws, operational status, and detailed programs for professional qualification system of QI were reviewed. Result: In the United States, a non-profit organization, Healthcare Quality Certification Commission (HQCC) has set the policies, procedures and standards in the field of health care quality. And qualification system of CPHQ (certified professional in healthcare quality) has been operated in order to authenticate the qualifications in the field of quality management. IBQH(international Board for quality in healthcare), a qualification system of experts in the United Kingdom, was designed to assist the qualification of professionals to improve the quality of healthcare. In addition, Health Research Center of Feinberg School of Medicine in Northwestern University has been operating Master's and doctoral degree programs in the field of the quality of care and patient safety and IHI (institute for healthcare improvement) open school was operating a professional training course related to the quality of care and patient safety. Conclusion: Quantity and complexity of information of the quality of care and patient safety have been increased. For reform of the health care system, a special training course of the expertise and leadership are needed. So far, there is no national professional certification courses in our nation. Therefore essential job skill should be acquired individually. For systematic and effective quality improvement activities, the educational and certification system with professional development model are needed.
