Survey on the current status of self-immolation attempts in Akita Prefecture: A cross-sectional survey

ObjectiveGiven the up to 70% fatality rate of self-immolation, with tragic consequences for survivors, proposals have been made for a global task force to prevent self-immolation. However, little research has recently been conducted on the actual situation of patients who attempt self-immolation in Japan. The current study aimed to investigate the actual situation of patients who attempt self-immolation in Akita Prefecture.ResultWithin Akita Prefecture, 13 individuals had attempted self-immolation in the past 5 years, with a predominance of a history of psychiatric disorders (46%). The following three novel findings were also revealed. First, patients with low a prognostic burn index tended to commit arson, while those with a high prognostic burn index tended to self-immolate. Second, patients attempting suicide tended to have a higher incidence of carbon monoxide poisoning. Third, those whose clothes caught on fire tended have more severe burns, regardless of whether suicide was attempted.ConclusionSelf-immolation tends to be serious, and prevention is imperative. In Akita Prefecture, the percentage of patients with a history of psychiatric disorders may be higher than commonly believed, and a more detailed understanding of the mental state of self-immolation is necessary in the future to develop effective prevention measures

The current study aimed to investigate the actual situation of patients who attempt self-immolation in Akita Prefecture. Result: Within Akita Prefecture, 13 individuals had attempted self-immolation in the past 5 years, with a predominance of a history of psychiatric disorders (46%). The following three novel findings were also revealed. First, patients with low a prognostic burn index tended to commit arson, while those with a high prognostic burn index tended to self-immolate. Second, patients attempting suicide tended to have a higher incidence of carbon monoxide poisoning.

TL06 - Experimental Evaluation of Performance and Mechanical Reliability for High Pressure CO2 Integrally Geared Compressor

LectureComprehensive tests were conducted for the main component as well as the complete machine and experimentally determined not only general performances such as overall aerodynamics and rotor vibrations but also usually unknown parameters. By implementing state-of-the-art techniques, the unknown parameters like rotor natural frequency and log decrement, impeller blade vibratory stress and thrust force on bearings could be accurately measured. The overall performance result met the expectations and the measurements had quantitatively verified the mechanical reliability of compressor. As an outcome of series of experimental evaluations it is concluded that this integrally geared CO2 centrifugal compressor is highly efficient with improved reliability can be used for high pressure applications, which will also contribute to energy saving and global environmental conservation
