  • When a missile is launched, a fracture-type canister cover should be properly broken by a collision with a missile or inner pressure of a canister. The fracture performance of a canister cover should be evaluated by a test using a real missile; however, it is unrealistic due to high cost and time restriction in a design stage. In this study, a test technique is newly developed to predict fracture performance of a canister cover. The test was design to have same kinetic energy with a real missile test when the cover is collide with a missile. The effectiveness of the suggested test technique was proved by comparing the test result with that of a real missile test.

  • This study conducted qualitative research using Geochang Wolseong Space Creative Science Museum as a case study to investigate the organizational and operational status of small local science museums during the COVID-19 pandemic, as a basic study for the dissemination of scientific culture and public understanding of science. To analyze the situation of the science museum, an evaluation framework was developed, and information obtained through various communication channels and in-depth interviews with information commissioners of the museum were used for the study. As of 2020, when COVID-19 was at its peak, this science museum showed a clear decline in sales and visitor numbers compared to the previous year. Despite this situation, the museum was found to be using crisis management methods such as introducing unface-to-face programs, managing exhibits, and using various promotional media. However, the shortage of professional personnel, excessive workload of employees, and absence of differentiation from other science museums remain as challenges to be addressed in the future for sustainable earth science.

  • 충남 금산군 복수면 백암리에 위치한 에너지생태과학관(관장 임상훈). 얼핏 주택 같아 보여 간판이 없었다면 그냥 지나쳤을지도 모른다. 하지만 평범해 보이는 이곳은 전국과학관협의회에 공식적으로 등록돼 있는 엄연한 진짜 과학관이다. 생태체험과 에너지의 쓰임 등을 한눈에 볼 수 있는 이곳, 에너지생태과학관에서 발길을 멈췄다.
