A closed chest injury is a frequent type of damage to the organs of the external respiratory system. Victims with such an injury may become the object of a forensic medical examination. The aim of the work was to determine the severity of closed blunt trauma of the chest based on the materials of a specialized clinic in order to determine additional diagnostic criteria for the severity of such an injury.123 medical cards of inpatients department, patients with chest injuries, who were treated at the Kharkiv Institute of General and Emergency Surgery named after V.T. Zaitsev. Forensic evaluation of closed injuries of the chest organs was carried out according to the degree of severity of physical injuries based on the materials of clinical observations.Severe injuries were found in 22 (17.9%) cases of injuries with the occurrence of a life-threatening phenomenon, namely, acute respiratory failure. Injuries of medium severity were found in 71 (57.7%) cases of chest injuries, mainly with rib fractures, due to the absence of danger to life. Mild injuries were found in 30 (24.4%) cases of chest injuries without rib fractures with intrapleural injuries and complications or mild chest injuries without any complications.It was determined that additional diagnostic criteria for closed injuries of the chest, which must be taken place when determining the severity of physical injuries, should be considered: dynamics and duration of restoration of post-traumatic morpho-functional changes of injured organs, loss of part or all of the respiratory organ (lungs), occurrence of life-threatening phenomenon.

Access to Justice in Eastern Europe, 2021
In this note, the authors study legal and procedural cases of the application of forensic research in the observance of the common European procedural guarantee ensuring the balance of justice during a trial: Art. 6 of the European Convention on Human Rights (right to a fair trial). Based on the current legislation of the European Union and Ukraine, peculiarities of legal regulation and application of forensic expert research during court proceedings are analysed. It is emphasised that established the approaches and practice of applying specific expertise in the countries of the European Union have some peculiarities. It is established that one of the ways to ensure the fairness of a court decision is using forensic science. While comparing the legal framework for providing justice in Ukraine and the European Union, the authors stressed the need to develop a separate policy guideline (strategy, concept, etc.), such as the Vision for European Forensic Science Area used in EU countries. Detailed analysis of the ECtHR case-law on the application of Art. 6 has made it possible to illustrate the specifics of applying forensic science by complying with the fair trial requirement. It is concluded that the adoption of a fair court decision becomes possible when: 1) the practice of law enforcement and legal provisions related to the dispute context are taken into account; 2) the circumstances of the case are established with the use of content and reference to evidence; 3) non-legal phenomena are taken into account, such as ethical, social, moral requirements accepted in society, etc.

Journal of Punjab Academy of Forensic Medicine and Toxicology, 2020
Introduction, Materials and Methods:In this study, an analysis of forensic medical reports was conducted in order to define new criteria for postmortem interval (PMI) assessment, to improve the accuracy of its determination by forensic medical experts. In the study, 2972 forensic medical examinations of corpses were analyzed. The location of the corpse, Degree of fatness, Body length, Age and Histological changes of some internal organs were observed. Dynamometry method was used for Postmortem Interval (PMI) estimation. The results were calculated using Spearman rank correlation coefficient.

2019 3rd International Conference on Advanced Information and Communications Technologies Aict 2019 Proceedings, 2019
This article discusses the methodology for determining the installation of digital images based on the entropy of noise. The distortion of the background noise occurs in certain cases (photomontage, retouching, etc.) in the corresponding areas of the image when digital editing tools are applied to it. Image studies were considered based on noise entropy analysis in order to identify retouching based on Comparison of the results of evaluating the level of clustering of the noise map of the investigated (retouched) fragment with the corresponding indicator of the control (original) image fragment.
Chemometric approaches in analysis of vegetable oils as a way to improve an efficiency of forensic examination
V. Rudniev, E. Simakova-Yefremian, V. Khosha, V. Ostropilets
Methods and Objects of Chemical Analysis, 2019
The approach to forensic examination performance through accelerated classification and identification research of vegetable oils is demonstrated. It includes derivatization of the original objects, analysis of obtained methyl esters mixture using GC-MS technique and applying of chemometric tools for gathering preliminary data. Subsequent processing of obtained chromatograms using principal component analysis for grouping of objects simplifies further detailed examination. An analysis of hidden correlations between variables and influence of the initial data on the first to third major components formation is provided. Using values of content of only 5 most widespread fat acids leads to satisfied visual pattern for prior recognition of oil samples. Applying of various split ratios is recommended at different stages of gas-chromatographic analysis. Split ratio 1 : 50 is recommended for gathering of data treated by chemometric methods and 1 : 2 is useful for determination of minor components presence as specific features.
