This paper describes the procedure for calculating the conformance probability of the results of the calibration with therequirements or specifications (standards or manufactures), including borderline cases. An original program created in Excel waspresented, which makes it easy to calculate in a Metrology Laboratory. During the development of this program, the recommendationsof the European Accreditation Team (EA), as well as the requirements of ISO / IEC 17025: 2017, were taken into account. The goal ofthis program is to provide the customer with a certificate of calibration with the declared uncertainty as well as the compliance of theresults of the calibration with the requirements or specifications. The program was developed for the needs of the MetrologyLaboratory, which is located in the company ORAO a.d. Bijeljina. The accreditation body at the accreditation examination of theMetrology Laboratory checked the results of the program. The international standard ISO 10576-1: 2003 describes the procedure forcalculating the conformance probability of the calibration results with the specification. According to the described procedure, eachcalibration result must first be graphically presented according to normal PDF (Gaussian distribution). Then, in order to determine theprobability of occurrence of any measured value, use the z-value and the standard surface tables below with normal PDF. In metrologylaboratories, this is a difficult and long-lasting process because the digital multimeter can be calibrated at even a hundred measuringpoints.

The purpose of the research work is to analyze the advantages and disadvantages of the «flexible» field of accreditation of forensic laboratories and the field of accreditation that has a rigid range. The development of standardization in forensic science, including the expansion of the number of forensic laboratories that build their activities in accordance with the requirements of the international standard GOST ISO/IEC 17025-2019 «General requirements for the competence of testing and calibration laboratories», encourages us to pay attention to this issue again. In the course of the study, the following conclusions were formulated. Insufficient clarity in defining the «flexible» scope of accreditation and differences in the understanding of its boundaries by the accreditation body, the forensic laboratory and the customer can lead to abuse by individual laboratories and the development of unfair competition. This argument in favor of abandoning the «flexible» field of accreditation for forensic laboratories seems to be much more weighty than the listed advantages of its practical application.

Research background: Conformity assessment as defined in the ISO/IEC 17000 standard shows that the specified requirements for the product, process, system, person or entity have been met. A special type of conformity assessment is certification, in which the assessment is carried out by independent organizations, which has been confirmed by an accreditation body. The current crisis related to the development of the COVID-19 global pandemic has forced many organizations to change traditional forms of operation and, where it was possible, switch to a remote mode of work. Purpose of the article: The need to adapt to new realities did not bypass the certification bodies that adapted to the emergency situation, using the possibilities of remote work, including as part of certification processes. The purpose of this publication is to indicate the context of the certification bodies’ operation and the impact of such proceedings on trust in the results of their work as well as to show the changes of the way of conducting certification audits by the certification bodies. Methods: For above mentioned matter, four certification bodies were analysed in the area of remote certification processes. The used methodology was a case studies including a direct interviews with certification bodies representatives. Findings and Value Added: The main findings are related to the following issues concerning that remote auditing processes ensure business continuity; there is an increased confidence in results among customers of certification bodies; changes in process costs.

Accreditation is the procedure by which the competence of a laboratory to perform a specified range of tests or measurements is assessed against a national or international standard. The accreditation covers the kinds of materials tested or measured, the procedures or methods used, the equipment and personnel used in those procedures, and all relevant systems that the laboratory has in place. Once accredited, the laboratory is entitled to endorse test results with their accreditation status which, if it has any validity, is an imprimatur of some degree of quality and gives the client added confidence in the results. Accreditation therefore benefits the laboratory, by allowing the laboratory to demonstrate competence in particular tests, and the client, by providing a choice of accredited laboratories that are deemed competent. Accreditation is part of conformity assessment in international trade. Conformity assessment leads to the acceptance of the goods of one country by another, with confidence borne of mutual recognition of manufacturing and testing procedures. Figure 9.1 shows the relation between accreditation and the goal of conformity in trade. For accreditation to be a cornerstones of conformity in trade, each laboratory that is assessed, in whatever country, must be judged against the same standard (e.g., ISO/IEC 17025), and the assessment process must be essentially the same from one country to another. The standards are indeed international, through the International Organization for Standardization (ISO), and the accreditation bodies themselves are scrutinized under the auspices of the International Laboratory Accreditation Co-operation (ILAC), being accredited to the ISO/IEC Standard 17011 (ISO/IEC 2004a). Full membership in ILAC is open to recognized bodies that operate accreditation schemes for testing laboratories, calibration laboratories, and inspection bodies that have been accepted as signatories to the ILAC Mutual Recognition Arrangement. They must maintain conformance with appropriate international standards such as ISO/IEC 17011 and ILAC guidance documents, and the must ensure that all their accredited laboratories comply with ISO/IEC 17025 and related ILAC guidance documents. Table 9.1 lists the full members and signatories of the ILAC Mutual Recognition Arrangement. The National Association of Testing Authorities (NATA) of Australia has the distinction of being the first accreditation body in the world (founded in 1947), and has long been in the vanguard of the approach to quality through accreditation.

The analysis of the normative document DOC GEN 010, which is regulating the procedure for conducting qualification examinations and the procedure for certification of personnel performing industrial non-destructive testing in the Nordic countries, has been performed. The document was developed by the organization NORDTEST, which is the single organ of the Nordic countries in the field of conformity assessment. The considered document establishes additional requirements for the preparation, content and procedure for conducting qualification examinations and the certification procedure in general, in relation to the current international standard ISO 9712. The scheme provides the qualification level of NDT personnel, which is recognized, and in some cases is regulated by state bodies and consumers of NDT services in Nordic countries.

With the declaration of independence of Ukraine, a new stage of the state has begun, accompanied by radical changes in all areas of public life. A person, his life and health, honor and dignity, integrity and security are determined by the highest social value. Therefore, the main duty of the state proclaims the assertion and protection of human rights and freedoms, for which a whole mechanism is created and functioning, each of which elements performs separate tasks in order to achieve a common goal. Forensic institutions are part of the relevant system and contribute to the establishment of objective truth in cases of violation of law, the rights and freedoms of participants in the process through an objective and fair trial or an objective basis for evaluating the results of pre-trial investigation bodies. In addition to performing these tasks, forensic institutions in Ukraine have a number of necessary conditions for carrying out conformity assessment activities, and therefore, with some transformations of the management system, technical and other improvements to meet the requirements of national standards, harmonized with relevant international and European standards in the field of assessment compliance, state specialized agencies can be accredited for compliance with the requirements of the standard ISO/IEC 17025 (as well as ISO/IEC 17020) and carry out conformity assessment activities in a specific industry. The article is devoted to the definition of administrative procedures for the accreditation of forensic institutions of Ukraine. Attention is focused on understanding the essence of administrative procedure and their place in the process of accreditation of conformity assessment bodies. The author analyzes the scientific approaches to considering the classification of the category “administrative procedure”. According to the results of the study, it can be stated that the administrative procedures for the accreditation of forensic institutions of Ukraine characterizes the procedure for authorized entities (national accreditation body of Ukraine) to carry out legally significant actions, the totality of which constitutes the legal process of accreditation; procedural requirements for these entities.

Recently we have observed the structure images of silicon in the (110), (111) and (100) projection respectively, and then examined the optimum defocus and thickness ranges for the formation of such images on the basis of calculations of image contrasts using the n-slice theory. The present paper reports the effects of a chromatic aberration and a slight misorientation on the images, and also presents some applications of structure images of Si, Ge and MoS2 to the radiation damage studies.(1) Effect of a chromatic aberration and slight misorientation: There is an inevitable fluctuation in the amount of defocus due to a chromatic aberration originating from the fluctuations both in the energies of electrons and in the magnetic lens current. The actual image is a results of superposition of those fluctuated images during the exposure time. Assuming the Gaussian distribution for defocus, Δf around the optimum defocus value Δf0, the intensity distribution, I(x,y) in the image formed by this fluctuation is given by

Zusammenfassung. Hintergrund: Die Abhängigkeit von Opioiden ist mit erheblichen gesundheitlichen Gefährdungen der Betroffenen und einer hohen Mortalität assoziiert. Derzeit werden insbesondere die dramatisch gestiegenen Mortalitätsraten in den USA diskutiert (‚opioid crisis‘), aber auch in Deutschland war in den letzten Jahren ein kontinuierlicher Anstieg der Drogentoten, überwiegend verursacht durch Opioide, zu verzeichnen. Die Risiken einer Opioid Überdosierung bzw. Intoxikation resultiert vor allem aus der hemmenden Wirkung der Opioide auf den Atemantrieb, die durch andere gleichzeitig konsumierte Substanzen noch verstärkt werden kann. Neben Erstmaßnahmen (Notruf, lebensrettende Basismaßnahmen der Ersten Hilfe) kommt auch der Einsatz des Opioidantagonisten Naloxon in Betracht. Methode: Literaturrecherche in PubMed, Cochrane Library und im International Standard Randomized Controlled Trial Number (ISRCTN) Register. Ergebnisse: Auch aus ethischen Gründen liegen bislang eher wenig systematische Untersuchungen zum nicht-ärztlichen Einsatz von Naloxon bei Opioidüberdosierung vor. Trotzdem kann nach aktuellem Stand geschlussfolgert werden, dass die intranasale Verabreichung vergleichbar wirksam mit einer intramuskulären Anwendung zu sein scheint. Bei Überdosierten, die nach erfolgreichem Naloxon-Einsatz aus unterschiedlichen Gründen nicht in einer Klinik gebracht wurden, wurden in ca. 1 %. Todesfälle dokumentiert. Falls 60 min nach Naloxongabe unauffällige Vitalparameter und auf der Glasgow Coma Scale mind. 15 Punkte erreicht werden, besteht wohl ein sehr niedriges Rebound-Risiko. Im Vergleich dazu ist das Auftreten von Naloxon-induzierten Entzugssyndromen deutlich häufiger, hängen jedoch von der Dosis und dem konsumierten Opioid ab, wie auch von der verabreichten Naloxon-Dosis. Schlussfolgerungen: Naloxon kann mittlerweile auch in Deutschland als zugelassenes Nasalspray verabreicht werden und ist daher im Prinzip auch für den Einsatz durch Ersthelfer geeignet. Verbesserte Rahmenbedingungen, wie z. B. spezifische Schulungen könnten dazu beitragen, Take-Home Naloxon als erfolgreichen Baustein zur Reduktion von Drogentod zu implementieren.
