We address, using probabilistic modeling and the extreme-value-distribution technique, the helicopter undercarriage strength in a helicopter-landing-ship situation. Our analysis contains an attempt to quantify, on the probabilistic basis, the role of the human factor in the situation in question. This factor is important from the standpoint of the operation time that affects the likelihood of safe landing during the lull period in the sea condition. The operation time includes (1) the time required for the officer-on-ship-board and the helicopter pilot to make their go-ahead decisions and (2) the time of actual landing. It is assumed, for the sake of simplicity, that both these times could be approximated by Rayleigh’s law, while the lull duration follows the normal law with a high enough ratio of the mean value to the standard deviation. Safe landing could be expected if the probability that it occurs during the lull time is sufficiently high. The probability that the helicopter undercarriage strength is not compromised can be evaluated as a product of the probability that landing indeed occurs during the lull time and the probability that the relative velocity of the helicopter undercarriage with respect to the ship’s deck at the moment of encounter does not exceed the allowable level. This level is supposed to be determined for the helicopter-landing-ground situation. The developed model can be used when developing specifications for the undercarriage strength, as well as guidelines for personnel training. Particularly, the model can be of help when establishing the times to be met by the two humans involved to make their go-ahead decisions for landing and to actually land the helicopter. Plenty of additional risk analyses (associated with the need to quantify various underlying uncertainties) and human psychology related efforts will be needed, of course, to make such guidelines practical.

Based on the probabilistic approach and using the extreme value distribution (EVD) technique, we address the helicopter undercarriage strength in a helicopter-landing-ship (HLS) situation. Our analysis contains an attempt to quantify, also on the probabilistic basis, the role of the human factor in the situation in question. This factor is important from the standpoint of the operation time and, hence, from the standpoint of the likelihood of safe landing during the lull period in the sea condition. The operation time includes the time required for the officer-on-ship-board and the helicopter pilot to come up with their go-ahead decisions, and the time of actual landing. It is assumed, for the sake of simplicity, that both these times could be approximated by Rayleigh’s law, while the lull duration follows the normal law. Safe landing can be expected if the probability that it takes place during the lull time is sufficiently high. The probability that the helicopter undercarriage strength is not compromised can be evaluated as the product of the probability that landing occurs during the lull time and the probability that the relative velocity of the helicopter with respect the ship’s deck at the moment of the encounter of the undercarriage with the deck does not exceed the allowable level. The developed model can be used when establishing the requirements for the undercarriage strength, as well as when developing guidelines for personnel training. Particularly, it can be employed for establishing the times that need to be met by the two humans involved to make their decisions for landing and to actually land the helicopter in a timely fashion. It goes without saying that plenty of additional risk analyses (associated with the need to quantify various underlying uncertainties) and human psychology related effort will be needed to make such guidelines practical.

Factor X

SummaryHuman factor X was purified by several different procedures yielding products which had varying amounts of factor VII and factor IX. Treatment with CHC13 during the fractionation of the factor X removed 95% of the factor VII and factor IX activity and the resulting factor X activated more slowly when incubated in 25% sodium citrate. Removal of residual factor VII by DEAE cellulose chromatography yielded a factor X which activated still more slowly and less completely. When the factor VII, removed by chromatography, was added to the chromatographed factor X, the ability to be activated in 25% sodium citrate was restored. Confirmatory evidence for the role of factor VII in this reaction was the inhibition of the conversion of the factor X by both DFP and SBTI.

This article discusses information on the study of terminology in Uzbek and world linguistics. Thematic grouping of banking and financial terms, which play an important role in Uzbek language vocabulary, is considered. The author gives the criteria for the distribution of terms into thematic groups, their peculiar properties examples to substantiate the hypothesis. The paradigmatic relations between the terms of this sphere are indicated. A structural analysis of the banking and financial terms of the Uzbek language is carried out.  On the basis of the anthropocentric approach, the role of the human factor in the banking and financial terminology of the Uzbek language is studied. Cognitive metaphors that exist in the terminology are considered.

Thinking in patient safety has evolved over time from more simplistic accident causation models to more robust frameworks of work system design. Throughout this evolution, less consideration has been given to the role of the built environment in supporting safety. The aim of this paper is to theoretically explore how we think about harm as a systems problem by mitigating the risk of adverse events through proactive healthcare facility design. We review the evolution of thinking in safety as a safety science. Using falls as a case study topic, we use a previously published model (SCOPE: Safety as Complexity of the Organization, People, and Environment) to develop an expanded framework. The resulting theoretical model and matrix, DEEP SCOPE (DEsigning with Ergonomic Principles), provide a way to synthesize design interventions into a systems-based model for healthcare facility design using human factors/ergonomics (HF/E) design principles. The DEEP SCOPE matrix is proposed to highlight the design of safe healthcare facilities as an ergonomic problem of design that fits the environment to the user by understanding built environments that support the “human” factor.

This volume highlights the central role of the human factor in cybercrime and the need to develop a more interdisciplinary research agenda to understand better the constant evolution of online harms and craft more effective responses. The term “human factor” is understood very broadly and encompasses individual, institutional, and societal dimensions. It covers individual human behaviors and the social structures that enable collective action by groups and communities of various sizes, as well as the different types of institutional assemblages that shape societal responses. This volume is organized around three general themes whose complementary perspectives allow us to map the complex interplay between offenders, machines, and victims, moving beyond static typologies to offer a more dynamic analysis of the cybercrime ecology and its underlying behaviors. The contributions use quantitative and qualitative methodologies and bring together researchers from the United States, the United Kingdom, the Netherlands, Denmark, Australia, and Canada.

Logistics continuously expands its application areas. In modern conditions, there is a need to apply logistics in areas not related to its traditional applications such as military and business spheres, resulting in the identification of a third area with the name social logistics. Social logistics aims to introduce a social (human) factor into the systems and to apply logistic principles and methods in solving the problems of society. Social logistics can be defined as a set of actions that ensure the effective functioning of social systems (such as a set of social phenomena, processes and subjects), applying the principles of logistics. For the purposes of this paper, a number of scientific approaches and methods have been applied, such as system approach, comparative analysis, critical analysis, synthesis and others. Social logistics plays an important role in national security, including economic and social security. The purpose of this paper is to explore the role of social logistics in enhancing national security, including economic and social security.

The theses reveal the problem of the connection between psychology and linguistics on the basis of translation activities. The role of the human factor of a translator is revealed, and the bonds between the type of translation and the characteristics of the person who does it is established For this purpose, a psycholinguistic experiment was carried out with the participation of 50 people to demonstrate the dependence of the psychological characteristics of the translator and the quality of the translated text using comparative analysis of translation. The data has confirmed the hypothesis about psychological phenomenon of translation.
