$CO_2$ 지중저장 기술은 가장 유력한 대용량 온실가스 감축기술의 하나이다. 이 기술을 적용하여 국제적으로 노르웨이, 알제리, 캐나다, 미국 등에서 이미 대규모 실증 및 상용화 사업이 수행되고 있으며, 호주, 일본, 네덜란드, 독일 등 그 밖의 여러 나라에서 다양한 내용과 규모를 갖는 중소규모 실증사업이 진행되고 있다. 한국도 소규모 육상 파일럿 저장 프로젝트와 중규모 해상 저장실증 프로젝트가 추진되어 착실하게 기술개발과 경험확보를 위해 노력하고 있다. $CO_2$ 지중저장 사업은 화석연료의 사용이 다른 에너지원으로 대체되기 전까지 지속적으로 확장될 것으로 예측되고 있으나, 온실가스 감축시장의 불안전성, 사업의 수익구조와 관련된 경제성, 누출에 대한 안전성 등의 위협요소를 갖고 있다. 따라서 이러한 위협을 극복하기 위해 많은 국가와 기업들이 저비용-고효율 지중저장 기술과 안전한 지중저장 기술의 확보를 목표로 연구개발 및 실증사업을 추진하고 있다. 한국의 경우에 저장소가 주요 포집원으로부터 상당한 거리를 갖고 있는 해저에 발달하고 있기 때문에 지중저장 사업의 경제성 확보가 매우 불리한 조건이다. 따라서 정부나 기업이 CCS 기술을 주요 온실가스 감축수단으로 채택하여 대규모 지중저장 사업을 본격적으로 착수하는 것을 주저하고 있다. 한국과 같은 불리한 조건을 갖는 국가의 경우에 특히 대규모 저장소의 확보를 포함한 저비용-고효율 지중저장 기술의 실용화가 절실하게 필요하다. 결론적으로 한국의 $CO_2$ 지중저장 사업의 성공적인 추진을 위해서는 대규모 저장소의 확보, 저비용-고효율 지중저장 기술의 개발과 실증을 통한 실용화, 중소규모 지중저장 실증사업으로 축적한 기술과 경험으로 대규모 지중저장 사업의 효율화 달성이 요구된다. 이를 위한 실천적인 로드맵과 프로그램의 작성과 착실한 이행 역시 중요하다. 이러한 기반이 착실하게 다져질 경우에 한국에서 대규모 CCS 통합실증과 $CO_2$ 지중저장 사업이 본격적으로 개시될 수 있을 것이다.

Virtual reality technology was initially developed for entertainment purposes such as games, movies, sports, and theme parks, but gradually expanded to a number of industries such as education, e-commerce, and health care,. Therefore, safety education content incorporating VR is also rising rapidly. However, the program activity on safety education in our country is still insignificant. Although rescue of patients with acute cardiac arrest using defibrillators is one of the most representative safety education, in 2014, defibrillators are rarely used in Korea to save the lives of patients and there are very few cases of using defibrillators. The use of automatic defibrillators and the importance of knowing how to use them for expanding accessibility are necessary. However, it is not easy to provide experience education only after completing the safety education in simple theoretical education. In this paper, we propose a automatic defibrillator training simulation system using virtual reality that can be freelu trained at any time.
