New computer technologies to determine postmortem interval by the Henssge method

Relevance. The article presents the results of the research regarding the chipping of certain categories of persons. Aim of the study is to try to determine the effectiveness of this mechanism for the protection of personal data and as an examination tool. Materials and Methods. The norms of the legislation of Kazakhstan and foreign countries concerning the protection of personal; scientific publications on the subject, as well as on the conduct of expert examinations were studied. The works of scientists, in which the problems of computer-technical examinations, and also successful application of the newest technologies in forensic medical examinations are marked, were singled out. It should be noted that there are no holistic works concerning the possibility of chipping citizens, as well as the application of this technology in various spheres, including forensic examinations. According to the results of the research, generalization of scientists' works, analysis of legislation, the authors of the work proposed the application of chipping of individual citizens for the protection of personal data. Conclusion. Based on the analysis and research of the legislation, the proposal on chipping of law enforcement officers, civil servants, employees of organizations that have access to state databases of personal data, employees of organizations that are the owner or operator of non-state database has been formulated. The proposed mechanism will provide an opportunity to increase the security and reduce the facts of unauthorized access to information, minimize the probable unlawful manifestations in relation to personal data and data with limited access. During the research the SWAT-analysis of the issues related to the chipping of certain categories of persons for the protection of personal data, as well as for other purposes was carried out. The strengths, weaknesses, opportunities and threats to the implementation of this technology were considered.

BACKGROUND: The main condition for the correctness of determining the postmortem interval by the method of thermometry of the deep tissues of the corpse is the constancy of the ambient temperature. This condition significantly limits the range of application of the method. The priority of thermometry of the core of the body in the diagnosis of prescription of death is explained by the slower cooling of deep tissues, which allows to increase the duration of the postmortem interval available for diagnosis, and less exposure to the influence of various random factors on the cooling process. The finite element models proposed recently can take into account almost all essential cooling conditions, including changes in ambient temperature, however, due to their high complexity, they require serious physical and mathematical training and technical skills, expensive software and postmortem computed tomography. For these reasons, they have not yet found wide application in expert practice. In this article, a mathematical model of cooling the core of a corpse at a linearly varying ambient temperature is proposed. AIMS: Construction a mathematical model of cooling the core of a corpse based on the Marshall-Hoare phenomenological law under conditions of linearly varying external temperature, to find a numerical algorithm for solving the model and to develop a computer program that implements it. MATERIAL AND METHODS: A direct analytical modeling of the corpse cooling under conditions of linearly varying ambient temperature was carried out, performed on the basis of the Marshall-Hoare phenomenological cooling law and focused on solving the problem of determination of the postmortem interval by rectal or cranioencephalic temperature. RESULTS: A mathematical model of cooling the core of a corpse under conditions of linearly varying ambient temperature has been developed. The chord method is proposed as a numerical algorithm for solving this model. The developed mathematical model and an iterative algorithm for its solution, as well as procedures for calculating interval estimates of the postmortem interval, are implemented in the C# language in the format of the Warm Bodies MHNH computer program. CONCLUSIONS: It is advisable to use the proposed model and the program implementing it in forensic medical expert practice when determining the postmortem interval by the rectal or cranioencephalic temperature of a corpse in conditions of linearly varying ambient temperature.
