Purpose: In the case of cavity discovered by ground penetrating radar exploration, it is necessary to accurately predict the filling amount in the cavity in advance, fill the cavity sufficiently and exert strength to ensure stability and prevent ground subsidence. Method: The cavity waveform analysis method by GPR exploration and the method using the cavity shape imaging equipment were performed to measure the cavity shape with irregular size and shape of the actual cavity, and the amount of cavity filling of the injection material was calculated during rapid restoration. Result: The expected filling amount was presented by analyzing the correlation between the cavity size and the filling amount of injection material according to the cavity scale and soil depth through the method by GPR exploration and the cavity scale calculation using the cavity shaping equipment. Conclusion: The cavity scale measured by the cavity imaging equipment was found to be in the range of 20% to 40% of the cavity scale by GPR exploration. In addition, the filling amount of injection material compared to the cavity scale predicted by GPR exploration was in the range of about 60% to 140%, and the filling amount of the injection material compared to the cavity size by the cavity shaping equipment was confirmed to be about 260% to 320 Purpose: The purpose of this study is to examine the types of crimes taking place in the metaverse, and to establish a crime prevention strategy and find a legal deterrent against it. Method: In order to classify crime types in the metaverse, crime types were analyzed based on the results of previous studies and current incidents. Result: Most of the crimes taking place in the metaverse are done in games such as Roblox or Zeppetto. Most of the game users were teenagers. Looking at the types, there are many teens for sexual crimes, violent crimes, and defamation, but professional criminals are often included in copyright infringement, money laundering using virtual currency, and fraud. Conclusion: Since the types of crimes in the metaverse are diverse, various institutional supplementary mechanisms such as establishment of police crime prevention strategies, legal regulations, and law revisions will have to be prepared.

코로나19로 인해 비대면 사회가 일상화되고, 가상세계를 구현하는 기반 기술 등이 발전하면서 3차원 가상세계인 '메타버스'에 대한 관심이 급증하였다. 메타버스는 다양한 분야의 활동을 할 수 있다는 점에서 기존의 사이버 공간에서 발생하는 법적 문제들과는 전혀 다른 문제들이 발생할 가능성이 있는데, 현재 메타버스 내에서 이루어지는 다양한 범죄 유형들에 대한 법적 제재나 안전장치가 제대로 마련되어 있지 않다. 이에 본 연구에서는 메타버스의 의의 및 현황을 살펴보고, 주로 문제될 것으로 예상되는 법적 쟁점 등을 검토하고자 한다.
