현재 국내에는 여러 가지 경보전달 시스템이 운영되고 있으나 국가 단위의 경보시스템은 민방위 경보시스템이 거의 유일하다 하겠다. 이러한 민방위경보 전달체계 현황에 대한 분석을 통해 현재의 문제점을 짚고, 향후 개선에 필요한 시사점을 도출하고자 한다. 민방위경보는 민방공경보와 재난경보를 포괄하고 있지만, 현재는 민방공경보에 치우친 운용절차와 경보전달체계를 갖고 있으며, 이는 근래에 들어 광역단위의 재난경보 상황에 대한 민방위경보시설을 이용한 대국민 경보대응이 점차 늘어나는 추세이긴 하지만 민방공경보에 치우친 경보전달체계로 인한 재난경보 대응 운용에서 제약을 받고 있음이 사실이다. 이에 본 논문은 민방위경보가 민방공경보와 재난경보를 동등한 수준으로 이해하고, 현재의 민방위경보 전달체계의 개선점을 토대로 시사점을 짚어내어 차세대 융합형 통합경보전달체계를 도출함을 목적으로 하였다.

In modern cosmology, it is controversial whether the existence of human consciousness can be used as evidence to support the hypothesis that many parallel universes are actualized. In this paper, we want to explore the nature of self-consciousness information that I am awake now. Consider the following experiment participating Al and Bob. We throw a fair coin on Sunday. If the coin lands heads we wake up just one of Al and Bob on Monday. If the coin lands tails we wake up both of Al and Bob. On Monday, at least one of Al and Bob will wake up, to what degree ought they believe that the outcome of the coin toss is heads? We will argue that the correct answer to this question is 1/3. To this end, we will argue the awakened person's information that "I am awake" is given to himself through a random procedure.

If we learn that 'Mrs Lee has two children and at least one of them is a daughter', what is our credence that her two children are all girls? Obviously it is 1/3. By assuming some other obvious theses it seem to be argued that our credence is 1/2. Also by just supposing we learn trivial information about the future, it seem to be argued that we must change our credence 1/3 into 1/2. However all of these arguments are fallacious, cannot be sound. When using the conditionalization rule to evaluate conformation of a hypothesis by an evidence, or to estimate credence change by information intake, there are some points to keep in mind. We must examine whether relevant information was given through a random procedure or a biased procedure. If someone with full information releases to us particular partial information, an observation, a testimony, an evidence selected intentionally by him, which means the particular partial information was not given by chance, or was not given accidentally or naturally to us, then the conditionalization rule should be employed very cautiously or restrictedly.
