An investigation into accidents in laboratories in universities in China caused by human error: A study based on improved CREAM and SPAR-H

Although considerable research has been devoted to improving safety in university laboratories, accidents, in that environment, have still occurred frequently at the cost of serious injury or even death of laboratory personnel. Currently, few Human Reliability Analyses (HRA) have been conducted with respect to a university laboratory. The aim of the research was to conduct a reliability study relating to human behaviour in a university laboratory to explore quantitatively the causes and influencing factors relating to the frequency of laboratory accidents. Improved Cognitive Reliability and Error Analysis Method (CREAM) and improved Standardized Plant Analysis Risk HRA (SPAR-H) were employed to assess Human Error Probability (HEP) of 23 subjects. The HEP calculated through improved CREAM proved more accurate than results obtained through improved SPAR-H. Unexpectedly, the results demonstrated that under similar environmental conditions, the HEP of subjects did not decrease with an increase in educational background, including additional experimental time and experience. Moreover, environmental conditions exerted greater impact on personnel reliability than Human Inherent Factors (HIFs) in laboratories. It is anticipated that the study would provide valuable insights, in respect of research methods, and to serve as a practical basis for lowering the accident rate in university laboratories.

Based on the analysis of the Professional Standard "Social Manager", the article characterizes a social manager’s professional competencies in terms of assessment, selection and development of social organization staff. The analysis has led to the conclusion that the training of future social managers with due regard for the relevant professional standard ensures simultaneous formation of their ability to: conduct a procedure for staff diagnosing for professional reliability according to the described methodology; make an unambiguous decision on a candidate’s suitability for a vacant position in a social organization; employees’ further development depending on the state of their professional reliability.

Health facilities preparedness to deliver maternal and newborn health care in Kilifi and Kisii Counties, Kenya

IntroductionHealth facility preparedness is essential for delivering quality maternal and newborn care, minimizing morbidity and mortality by addressing delays in seeking skilled care, reaching appropriate facilities, and receiving emergency care. A rapid assessment of 23 government health facilities in Kilifi and Kisii counties identified poor maternal and newborn indicators in 16 facilities. The Access to Quality Care through Extending and Strengthening Health Systems (AQCESS) project supported these facilities with training, equipment, and referral linkages. This study focuses on facility preparedness of the 16 facilities to deliver maternal and newborn health services, specifically delays two and three at the end of the project implementation.MethodsA descriptive cross-sectional study was carried-out on behalf of AQCESS project team by respective county ministry of health in-charge of reproductive maternal newborn and child health programs and trained nurses and medical doctors from Aga Khan health services in December 2019. The study evaluated the accessibility and reliability of drugs, commodities, equipment, personnel, basic necessities (such as water and electricity), and guidelines using validated World Health Organization service availability and readiness assessment tool. The findings of the assessment are presented through frequency and percentage analysis, along with a comparative analysis between the two counties.ResultsAll the 16 facilities assessed offered routine antenatal care (ANC) and normal delivery, but only two provided comprehensive emergency obstetric and newborn care (CEmONC). Most essential medicines, commodities, and required equipment were available. BEmONC and CEmONC guidelines were present in Kilifi, not in Kisii. One staff member was available 24/7 for cesarean section (CS) in each county, with one anesthetist in Kilifi. Electricity was accessible in all facilities, but only half had secondary power supply. Facilities offering CS had backup generators.ConclusionThe Facilities assessed had necessary drugs, commodities, equipment, and requirements, but staffing and guidelines were limited. Kilifi outperformed Kisii in most indicators. Additional support is needed for infrastructure and human resources to deliver quality maternal and newborn health services. Continuous monitoring will facilitate resource allocation based on facility needs.

An improved signal detection algorithm for a mining-purposed MIMO-OFDM IoT-based system

<abstract> <p>The coal mine internet of things (IoT) communication system is used for real-time monitoring of mining production to ensure the safety and reliability of personnel and equipment in the mine. To eliminate multipath fading in the process of wireless communication in mines, multiple-output multiplexing (MIMO) and orthogonal frequency division multiplexing (OFDM) technologies are introduced. In this paper, a wireless communication system architecture of IoT in mining based on MIMO-OFDM is constructed. Aiming to solve the problems of intersymbol interference and frequency selective fading at the receiver, an improved minimum mean square error ordered successive interferences cancellation (MMSE-OSIC) signal detection algorithm is proposed. First, the signal-to-interference plus noise ratio of the received signal is calculated and the calculation results are sorted. The lowest signal-to-noise ratio is selected as the weakest signal layer. Then, the MMSE-OSIC algorithm is used to extract all of the signals, except the weakest layer. Finally, a maximum likelihood (ML) algorithm is used to traverse the whole signal domain; the signal symbol with the smallest distance from the weakest signal layer is found as the original signal of the weakest signal layer, and it is combined with the signal detected by MMSE-OSIC; then, the final signal detection result is obtained. The simulation results show that, compared with three benchmark algorithms, the proposed MMSE-OSIC algorithm has better signal detection performance under the conditions of different modulation methods and different channel numbers.</p> </abstract>

СТРАТЕГІЯ ЗАБЕЗПЕЧЕННЯ ФІНАНСОВОЇ БЕЗПЕКИ БАНКІВСЬКОЇ УСТАНОВИ ТА СУЧАСНІ АСПЕКТИ ЇЇ ДІАГНОСТИКИ

The essence of the financial security of the banking system has been clarified. The main threats to the financial security of banking activities are presented. Internal threats to banks include: unbalanced structure of assets and liabilities; risky credit policy; insufficient level of innovative activity; low reliability of bank personnel; lack of liquid assets; lack of strategic management and effective marketing. External threats include: high level of competition, mistrust of banks, ineffective policy of the National Bank of Ukraine, unfavorable political and social situation. It is noted that the bank's security strategy is a set of measures of a managerial, regulatory, organizational, legal and economic nature, which contribute to the creation of a proper competitive environment in the financial market and ensure the protection of the legitimate interests of bank depositors and clients. The mechanism of formation and implementation of the strategy for ensuring the bank's financial security is considered. Emphasis is placed on the fact that the main strategy for ensuring bank security is formed for the long term and is a general management plan aimed at reducing the impact of destabilizing factors on the state of security, taking into account the intensity of their action at each stage of the life cycle of a financial and credit organization. It is noted that the inclusion of one or another set of risk neutralization methods in the protection strategy takes place according to the rule, where the main criterion is the minimum expected costs for the implementation of certain risk neutralization methods and the costs that cannot be avoided when applying the corresponding set of these methods. Measures to ensure the financial security of banking institutions are proposed. It was concluded that in order to strengthen the level of the bank's market security, it is necessary to use the bank's integrated marketing approach to managing banking activities, which will allow to understand the client's needs as quickly as possible and find the optimal solution for their satisfaction. In addition, bank security must be ensured both at the level of an individual bank (based on the implementation of bank management measures) and at the level of the banking system (based on the implementation of state measures aimed at protecting the interests of the bank and the banking system as a whole from internal and external threats).

Организация советской высшей вневойсковой подготовки во второй половине 1930-х гг.

The article assesses organizational changes in the process of higher pre-conscription military training in civilian educational institutions of the USSR in the second half of the 1930s. This system was the most important element of training Red Army reserve personnel for the upcoming Great Patriotic War. It was created in 1930 during forced industrialization when specialists were in urgent demand in the national economy. Thus, the Soviet leadership faced the task of creating a system permitting to train future commanders without discontinuing their profession educational. The current geopolitical situation increases relevance of studying history of military personnel training in the USSR in the 1930s. The novelty of this study is that it describes for the first time the process of transformation of the institute of higher pre-conscription military training in civilian educational institutions of the USSR in the second half of the 1930s. The research is based on the office documents of the People's Commissariat of Defense and those of military districts, stored in the fond 62 of the Russian State Military Archive. The author has established reasons that influenced structural changes in the process of training reserve personnel and identified decisions of the top military leadership on the matter. The article also reveals the impact of the Red Army’s repressions of 1937–38 on the system of higher pre-conscription military training. It is noted that in the new conditions, the approach to students selection changed, more attention was paid to political reliability of personnel and students. In addition, the top military leadership decided to reduce the period of higher pre-conscription military training from three to two years, while increasing training hours. The list of educational institutions with higher pre-conscription military training also changed. However, by 1938 the geopolitical situation had changed significantly, and the position of the USSR in international politics had deteriorated greatly. The military leadership faced the problem of forced training of personnel for the regular army, and therefore the institute of higher pre-conscription training was no longer relevant. In August 1938, the system was eliminated; there was a transition to accelerated pre-army training.

Türkiyedeki yüksek hızlı tren sisteminde yolcu sadakatinin belirleyicileri

Satisfaction and loyalty of passengers is important for a public transportation system provider especially if a competition exists between service providers. The factors affecting passenger satisfaction and loyalty must be determined by managers, operators, and decision makers. In this study, 900 passengers using High Speed Rail System between two cities (Ankara and Eskişehir) in Turkey were asked to rate their perceptions about the service they get. Their ratings are analyzed in terms of effects of factors on satisfaction and loyalty. The factors taken into consideration are service quality dimensions (which have ten sub-criteria), trust, perceived value, involvement, image, satisfaction and loyalty. Structural equation modeling is used to examine the direct and indirect relationships between these factors. Image is found effective on almost all factors analyzed: Perceived value, Trust, Satisfaction, Involvement and Loyalty. According to results, two important dimensions of service quality among ten dimensions came forward as most effective on satisfaction: Reliability and Interaction quality of personnel, which is found effective also on trust, satisfaction and involvement. On loyalty, the effective factors are found as perceived value, involvement, satisfaction and image.

A human reliability analysis methodology based on an extended Phoenix method for severe accidents in nuclear power plants: Qualitative analysis framework

The mitigation of the Fukushima accident exposed the detrimental action of human errors once again. However, deficiencies in existing human reliability analysis (HRA) methods prevent the effective prediction and analysis of potential human errors during the mitigation of severe accidents following core damage. To address this problem, this study presents a qualitative analysis framework for emergency response personnel (ERP) reliability analysis under severe accident conditions. This framework is developed using the Phoenix HRA method in conjunction with analyzing the ERP response characteristics and human-related issues from previous accidents, literature surveys, drill observations and interviews, as well as an assessment of the applicability of existing HRA methods. The analysis framework includes the establishment of an ERP response tree and a human failure fault tree (FT), as well as the identification and compilation of ERP cognitive functions, human error modes (HEMs), performance-influencing factors (PIFs), and the construction of Bayesian belief networks, to provide methodological guidance for the prevention of human errors under severe accident conditions.

Регуляторно-личностные факторы надёжности деятельности оперативного персонала энергетических объек

Relevance. The article presents research results regarding personal and regulatory factors influencing the reliability of personnel in power plants. We discuss the possibility of integrating different psychological approaches to assessing functional reliability. We had assumed that including dynamic variables (acute and chronic stress manifestations, “internal cost” of activity) and stable personal factors in the analysis will permit to compare their contribution to psychological stability and reliability. Methods. The main indicators of the study include: personality traits (ITO, Sobchik, 1998); functional components of self-regulation (“SSPM with a reliability scale”, Morosanova, Bondarenko, 2015); occupational stress indices (IDIKS, Leonova, 2006). The number of errors in the cognitive microstructural tests “Attention Span” and “Stimuli Recognition”, S. Sternberg’s model) was assessed as objective parameter of the operators’ reliability. The sample includes 378 employees of power plants (average age 41): 31 people are middle managers (chiefs and their deputies) and 347 are operational and technical personnel (engineers, electricians, controllers). The results indicate that the main psychological predictors of low occupational stress manifestation include: (1) regulatory processes and features (modeling performance conditions and assessing the result); (2) personality traits (high extraversion and emotional lability, moderate anxiety, sensitivity and self-sufficiency). The level of self-regulation determines differences in indicators of performance reliability of the operating personnel (error-free completion of microstructural tests).

Increasing the reliability of stress tolerance prediction as part of aptitude screening of flight specialists

Aim . The paper describes a research aimed at improving the reliability of stress tolerance prediction as part of aptitude screening (AS) of flight school applicants using a proprietary objectifying method of Stress Tolerance Assessment. Stress tolerance (ST) is an important psychophysiological professional quality and serves as one of the factors ensuring both successful flight training, and further professional flight work. However, the methods recommended in regulatory documents for the purpose of ST identification as part of AS are not efficient enough and are affected by subjective factors. Therefore, an objective and thus more efficient method is still required. Methods . The method was developed based on the analysis of subject-matter literature and own experience. Stress stimuli and methods of indicator recording were selected based on their empirical verification. The stress-inducing property of the stimuli was confirmed by the pulse rate increase by 40 – 100% and higher, associated behavioural manifestations and significant dynamics of mental productivity in the course of tests. Out of the methods of mathematical statistics, the authors used correlation analysis. Results . The method of ST assessment is based on the Reakor multifunctional psychophysiological system by the Medicom MTD research and development company from Taganrog, Russia, with a proprietary procedure built in the system’s software. As stress stimulus material and for performance assessment, arithmetically complicated problems were selected, whose solutions involve a larger portion (areas) of the brain than verbal tests. In order to eliminate the effect of habituation and learning, the arithmetic tests were displayed one by one on a computer screen in a random order. The 3-4-second time interval between individual problems was selected based on premises of aviation psychology and tests conducted on a group of students. The sample consisted of 1135 male applicants to the higher flight school in 2016. Correlation analysis shows that the correlations between the external criterion indicators (successful simulator training and flying practice) and the integrated ST indicator are statistically significant: the higher is the ST indicator measured in the course of AS using the respective method, the higher are the expert estimates of the simulator training and flying practice. Conclusion . Thus, the conducted research showed that the application of the developed method of ST assessment in the course of higher flight school AS ensures higher predicted stress tolerance in the selected candidates as the psychophysiological factor of professional efficiency and reliability of flight personnel.

Ensuring Cybersecurity of Digital Production Using Modern Neural Network Methods

The transition from the information economy to the digital one presents new challenges for society associated with the development of disruptive technologies, a network of cyber-physical systems, artificial intelligence and big data. When creating digital platforms, a number of difficulties arise: the large size of the digital infrastructure and its heterogeneity, poorly established information interaction between segments, the lack of a unified approach to ensuring cybersecurity and a high dependence on the qualifications of personnel and equipment reliability. The introduction of the digital economy leads to an increase in the risk of cyber threats associated with access control problems between information flow regulation and control systems. To solve the problems of detecting cyber threats, it is proposed to use generative adversarial neural networks. Algorithms for learning and testing a neural network were presented. The results of the experiments have demonstrated that the proposed solution is highly accurate in detecting cyberattacks.

Standardization of digital technologies of simulator systems as a method of ensuring reliability of conditions of service of power engineering facilities (part 3)

The article deals with the issues of creating standardized digital simulator systems, in order to ensure reliable service conditions of electric power facilities. The article presents the reasons which prevented all simulator designers in power engineering from ensuring efficient functional properties of simulation systems for operator training. The primary problem was the lack of methods and procedures for developing the simulator’s core subsystem – a mathematical model of a power facility, because the existing standards, norms and technical requirements were only concerned with the structure and functional properties of simulator subsystems. These reasons and circumstances determine the current state of the Russian simulator production; its negative trends are covered in depth in this article. There is also a critical assessment of simulators designed by some of the Russian engineers: these machines are not conducive to improving the quality of training and retraining of operating personnel of power companies. The article identifies the concept of a physical-statistical approach to developing a power facility simulation model: it includes preparing an analytical description of the physical processes at the simulation object, adapted to real processes, taking into account real-time sample observation, collecting and analyzing statistical procedure data, adjusting the model structure and assessing the parameters and states of the facility model. This approach concept defines the main aspect of modern methodology for setting and achieving all goals related to the energy facility modeling for simulator construction. Western sanctions and import substitution requirements dictate the necessity of developing home-grown technology, manufacturing and introducing new equipment in power engineering, including the sphere of simulator production. The designers of Russian simulators should understand that the principles and technical rules of power equipment imported from Western countries, including automatic control systems for such equipment, are different from the ones which the Unified Power System of Russia is based on. It is emphasized that, in real operating conditions of Russian power facilities, reliability of operation, maintenance and repair personnel is essential. It is noted that, in order to improve this reliability, it is necessary to develop a new regulatory document which would fully explore its topic: ensuring consistent and efficient methods for developing the structure and functions of digital technological systems for training power facility personnel.

Sağlık Hizmetlerinde Memnuniyeti Etkileyen Faktörler: Güven ve Kalite

In this study, we investigated the effect of the perceived trust and quality of health personnel providing home health services on the satisfaction of individuals receiving home health care. Individuals who receive free home health care constitute the universe of our research. The sample of the study consisted of 151 patients with health conditions who could participate in the survey. To collect data in this study, we applied the “Trust” Scale developed by Oly Ndubisi (2007), the “Satisfaction” Scale developed by Sevilmiş (2015) and the “Staff Quality” Scale developed Yıldırım (2017). The SPSS 21 Package Program was used to analyze the data obtained from the study. As a result of the regression analysis, the quality of staff (R2=0,234) and trust (R2=0,345) have a profound effect on patient satisfaction. Quality of staff and trust affect have a middle level (R2=0,420) positive effect on patient satisfaction. The research has limitations in terms of the fact that patients are not healthy enough to answer multi-item questionnaires, not all factors affecting patient satisfaction are included in the model, the results obtained from the research are about people who benefit from home health services, the size of samples and the sampling technique. The literature on home healthcare services has a very narrow scope. In the literature, no studies regarding personnel reliability and personnel quality affecting the satisfaction of patients benefiting from home health services have been encountered. In this context, our research differs from similar research in the literature.
