Abstract

In Japan, a new cause-of-death investigation system and related new laws were enacted in the mid-2010s. These laws provided for an autopsy system for non-criminal unnatural deaths and a medical accident investigation system outside the criminal justice process for health care-related deaths. We retrospectively explored changes in the number and characteristics of medico-legal autopsy cases of health care-related deaths in Chiba Prefecture, Japan, and examined trends over time during these reforms. We found that the percentage of forensic autopsies based on the Code of Criminal Procedure for health care-related deaths had decreased significantly. The number of autopsies of accidental and unintentional deaths in nursing homes, which are not covered by the newly established medical accident investigation system, has been increasing, reflecting the ageing of society. The trend toward decriminalisation of health care-related deaths was expected to contribute more to medical safety if the scope was expanded and a system for disclosure of autopsy information was established.

Abstract

We propose a music retrieval method that uses onomatopoeia query to enable easy and intuitive retrieval of music even for users without musical knowledge. When we use a music retrieval system, we usually need some information on the music, such as artist names or lyrics. However, if we do not know such information, it is difficult to retrieve the music, especially instrumental music. In the proposed method, we create an index of changes in note length and pitch in all of the music to be retrieved in advance. When searching, the proposed system extracts the change in note length and pitch from the user's query. The extracted information is used to calculate the similarity of a musical piece and the query by using a dynamic programming matching algorithm. The proposed system ranks a musical piece on the basis of similarity. The music format of the retrieval target is MIDI. In this paper, the result of retrieval experiments with the proposed method is shown. [ABSTRACT FROM AUTHOR]
