An accidental death due to Freon 22 (monochlorodifluoromethane) inhalation in a fishing vessel

We have firstly presented a case using post mortem corrosive method in forensic medical practice after coronary stent implantation. Occlusions, fate of side branches could be detected during the clinical diagnostic angiography, intravascular ultrasound, computed tomography; however, the forensic medical determination of cause of death, identification of complications needs a careful post-mortem investigation. The injection-corrosive method seems to be a useful assistance in the characterisation of pathomorphological changes after stent implantation. Besides the classical techniques of histology, immunohistochemistry, electron microscopic investigation we have introduced a new synthetic resin corrosion cast method. This three-dimensional corrosion cast preparation may provide new data about the actual morphological condition of the coronary vessels and a better understanding of the pathomechanisms of sudden cardiac death after percutaneous coronary intervention.     

Why Japanese citizens evaluate the new indirect tax as unfair: Fairness criteria and their relative importance

The study examined citizens' fairness evaluation of the consumption tax recently introduced in Japan, and explored the underlying criteria and their relative importance in judging the fairness of the tax and the procedural fairness by which the tax was introduced. Five dimensions were obtained in factor analysis. Multiple regression analysis revealed that three dimensions contributed to total fairness of the tax: Procedural Fairness, Outcome Evaluation, and Affective Responses. Further analyses revealed that ramming the bill, sufficient discussion, and reflection of citizens' opinions were crucial for Japanese citizens judgment of procedural fairness. The results supported Leventhal's theory: ethicality, accuracy, and correctability were important.     

Quantitative evaluation of volatile hydrocarbons in post-mortem blood in forensic autopsy cases of fire-related deaths

Volatile hydrocarbons in post-mortem blood from victims of fires were analyzed quantitatively by headspace gas chromatography mass spectrometry. The benzene and styrene concentrations in the blood were positively correlated with the carboxyhemoglobin (CO-Hb) concentration, which is evidence that the deceased inhaled the hydrocarbons and carbon monoxide simultaneously. By contrast, the concentrations of toluene and CO-Hb in the blood were not significantly correlated. This lack of correlation could be explained by two different sources of toluene, with low blood concentrations of toluene arising when the deceased inhaled smoke and high blood concentrations of toluene arising when the deceased inhaled petroleum vapor or other unknown vapors. The quantity of soot deposited in the respiratory tract was classified into four grades (-, 1+, 2+, 3+). The mean CO-Hb concentration in the 1+ soot group was significantly lower than those in the 2+ (p<0.05) and 3+ (p<0.01) soot groups. The blood CO-Hb concentrations in the 1+ soot group were all below 30%. Those indicated that the deceased aspirated smoke that contained both soot and carbon monoxide. The wide variation in CO-Hb concentrations for each soot classification could be caused by the different types of smoke produced by different materials. For example, petroleum combustion with a limited supply of oxygen, like in a compartment fire, may produce a large volume of dense black smoke that contains a large quantity of soot. Soot deposits in the airways and the blood CO-Hb concentration are basic and essential autopsy findings that are used to investigate fire-related deaths. The quantitative GC-MS analysis of blood volatile hydrocarbons can provide additional useful information on the cause of the fire and the circumstances surrounding the death. In combination, these three findings are useful for the reconstruction of cases.     

Does commitment affect the meaning of fairness?: Commonality and stability of fairness criteria in a political setting

This study explored political fairness criteria in Japan: examining their commonality and stability. Respondents were divided into three groups according to their commitment to the incumbent Government, as measured by neutrality, trust, and respect. Regression analyses revealed that Procedural Fairness was the commonly used criterion in judging the total fairness of the consumption tax. Citizens' commitment affected fairness criteria and their relative weights. Another regression analysis was performed to examine the meaning of procedural fairness. A comparison with our previous study (Takenishi and Takenishi, 1990) indicated that the procedural fairness criteria remained stable: however, voice became a criterion because of the Government's campaign. Results suggested than democratic ethicality, which consists of social values and beliefs, was important.Each author contributed equally.
