By studying their systemic properties, the possibility of scientific forecasting in the development of the legal system tendency, determining courses of the most effective steps to improve the entire mechanism of legal regulation of forensic relations’ complex is increasing. \u0000The article purpose is to conduct research on the prerequisites for systematizing the modern array of the forensic science legal basis in Ukraine and to identify theoretical and applied peculiarities for the formation of the general part content in the system of forensic law sources. \u0000To uncover the problem and subject of examination, as well as to accomplish the tasks, the synthesis method was used, which helped to identify the main areas of legal regulation and the system of general forensic relations, the formal legal method helped to clarify the content of forensic legislation legal norms. \u0000Attention is drawn to the fact that the legal construction of the general part of the current Law on judicial examination from the point of view of legal technique in general and rule-making in particular is an example of legislative anachronism in which neither substantive nor formal requirements of the culture of law-making are properly observed, what directly complicates its implementation, compliance and application. \u0000The need for injunctions of a general nature is emphasized with the purpose for a better understanding of the essence, objectives and content of specific injunctions. In general provisions of the basic act of forensic legislation it is offered to combine injunctions that define: the concept, terminology, content, legal basis, objectives, principles of forensic activity and their content, subject and object composition of forensic examination, as well as the powers of state, interdepartmental, departmental and public bodies on state regulation and forensic management. \u0000It has been established that the content of most sources of forensic law testifies to the differentiation of their injunctions, which can be carried out in a special part according to three generic criteria: the type of forensic activity entity (based on departmental subordination, form of ownership); type of forensic examination; type of legal proceedings. \u0000Arguments on the lack of a single scientifically based system of interconnected regulatory legal acts of forensic legislation are presented, which, as a result, created the social prerequisites for its systematization in the form of codification. The course of the highest degree of legislation perfection is substantiated, which should be presented in the form of Forensic Code of Ukraine.","PeriodicalId":340932,"journal":{"name":"Theory and Practice of Forensic Science and Criminalistics","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128390455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In broad terms, it is possible to take into account supporting of all types of forensic units activities (managerial, organizational, scientific and methodological, etc.) with necessary information, including their main type of activity – the collection and investigation of forensic objects during investigation. In a narrow sense, information support is considered as a process of information systematization, accumulation and processing, which is the basis for the development of criminal records. \u0000  \u0000The problems of information support of forensic activity are investigated, which is a system of actions aimed at obtaining information when analyzing the situation at the scene, examination of objects and traces seized during other investigative (search) actions; accumulation, systematization of the information received and its placing in criminal records; use of information for forensic examination. The problematic issues that arise in the activities of investigators, investigators and forensic experts at each stage of obtaining information and its use while forensic records development and in the preparation and conduct of forensic examinations are considered. \u0000The main problems that exist in the practice of pre-trial investigation bodies are highlighted. When collecting forensic information in the practice of investigating criminal proceedings, problems arise while reducing the quantity and quality of physical evidence seized during inspection of crime scenes, due to insufficient training of forensic investigators and logistics support of investigation units. Another problem is insufficient interaction of forensic experts from state expert institutions with police investigators, which manifests itself in inconsistency of the subject under study, improper design of materials offered for examination, insufficient number of samples for forensic identification.

This is due to the fact that these traces are most often found at the scene of the incident, as well as by the fact that they contain most valuable and significant information needed for criminal investigation. Forensic examination of footprints and footwear traces of a person are among the most common trace evidence examinations encountered in practice, and defining a human height based on footprints is relevant and important in terms of obtaining primary (up-to-date), and later evidentiary information for a successful investigation and crime detection. The approximate height of a person, as indicated in the current trace evidence literature, can be established by using a certain number of the most common methods, one of which is to establish height by the total length of the trace. However, the existing today methods for calculating human height by foot traces (footprints) have certain disadvantages, which are mentioned in this article. \u0000The article purpose is to analyze current known methods and techniques for determining human height by footwear (feet) traces, conducting practical research on a given topic, indicating objective defects and the presence of a number of errors that are not taken into account while calculations, formulation of a reasonable conclusion based on the analyzed results of an examination. \u0000In the course of the analysis of forensic practice, a number of problematic issues was identified that make it difficult to objectively determine a person’s height by footwear traces, namely: non-conformity between the real value of human height and the height value calculated according to the most common formulas given in the forensic literature; non-compliance with standards by manufacturers while the production of shoes; lack of catalogues on shoe production, information on trace formation and the environment when examining a crime scene. All the above factors have a significant impact on the establishment of real human height by foot traces (footprints), and the absence or variability of at least one of these indicators leads to significant differences in the final values. Our research has shown that each individual foot length corresponds to not one, but several height indicators at once. At the same time the limit intervals of the height range are not the same for all foot lengths (3-20 cm for men and 6-20 cm for women).

The research of tires of a truck has been conducted, an example of an expert research of tires is resulted, as a result of which the causes of damage of tires were established. The tire connects the vehicle to the road, perceives its weight, braking effort and dynamic impact that arises due to the roughness of the road surface. It is not uncommon for the vehicle to operate even on roads with a satisfactory road surface and damage to the tires. Damage to the tires can be generated as a result of industrial damage (factory defect) and as a result of operational damage. The most common and serious cause of premature wear and damage to tires is non-compliance with the established air pressure norms and overload tires. Changing the configuration of the profile and increasing the deformation of the bus cause an increase in the voltage in its material. As a result, it increases its premature wear. At increased load (overload) the tension voltage in the places of contact of the tire with the road increases and its specific pressure on the road, from which the tread wears away more quickly.
