An Assessment Study on Consumer Knowledge and Purchasing Behavior Regarding Food Safety

Economic and technological developments affect consumers’ purchasing behaviors along with their lifestyles. Understanding consumer characteristics and purchasing behaviors is of great importance for companies in determining target markets and preparing marketing programs. The aim of this study is to determine consumers’ level of knowledge about food safety and their purchasing behavior regarding food products. For this purpose, a face-to-face survey was conducted with 400 consumers selected using the Simple Random Probability Sampling method. About 76% of the consumers participating in the study have heard of the concept of food safety. It was found that consumers primarily consider health safety, the expiry date, and the cleanliness of the place of purchase when buying food products. They prefer the products they consume to be fresh and mostly shop at supermarkets and hypermarkets. It was also determined that 53.8% of consumers pay partial attention to human health conditions in the places where food is produced, and 69% are willing to pay more for packaged foods. The level of food safety knowledge among consumers will provide important feedback for food producers and policymakers, guiding the creation of more effective and safer food systems that address consumer needs.

Brewing Happiness Design Aspects of Coffee Representation in Cozy Games

This paper examines the way coffee is represented and used in cozy games. As a genre, cozy games are defined by the concepts of safety, abundance, and softness, which together establish a sense of coziness. Coffee, commonly associated with casual and friendly social situations, has a potential to be a strong contributor to coziness within cozy games. To explore this, the authors identified 27 cozy games containing coffee-related elements, and then performed a qualitative analysis on their content. The analysis found it was comparatively rare for coffee themes to strongly impact the overall game experience; however, there was a significant tendency for coffee to amplify the game’s overall sense of coziness.

ENSURING THE CELERITY OF THE PROCEEDINGS THROUGH THE CONTESTATION REGARDING THE DURATION OF THE CRIMINAL PROCESS

The concept of public safety is also manifested by respecting the fundamental rights of the person during the judicial proceedings, rights among which is the right to resolve the case within a reasonable time. From this perspective, to ensure the speedy resolution of criminal cases, in the regulation of the current Romanian Code of Criminal Procedure, the contestation regarding the duration of the criminal process was introduced, an institution that allows the request to expedite the resolution of the case if the criminal prosecution or trial activity is not carried out in a reasonable time frame. In this context, the present work addresses the institution of the contestation regarding the duration of the criminal process, bringing to attention also some jurisprudential aspects regarding the need for the interpretation and uniform application of the provisions of the Code of Criminal Procedure in the matter of the admissibility of this contestation. Also, using documentation, observation, interpretation and scientific analysis as research methods, this study discusses the consequences of not complying with the term established for the resolution of the case in the situation of admitting the contestation regarding the duration of the criminal process. The paper concludes with a concrete proposal for a ferenda law, regarding the establishment of a processual sanction, which will ensure the effective role of the contestation regarding the duration of the criminal process as a genuine accelerator remedy in case of exceeding the reasonable duration of the procedures.

Special requirements have also been established for medical personnel who have the right to carry out medical procedures related to the transplantation of human organs and tissues. The domestic legislator is actively implementing the concept of biological safety in the field of VMT use by establishing certain criteria and restrictions for this type of assistance, which ensures citizens the right to receive qualified, high-quality medical care in the field of transplantation and donation of human organs and (or) tissues.

Application of the scoping tool and AMBER model in radiological safety assessment of the barrier systems of the borehole disposal system for the disposal of disused sources in Ghana

Radiological safety assessment was carried out to assess the integrity and longevity of the barrier systems of the borehole disposal system (BDS) for the disposal of disused sources in Ghana. The design of the BDS incorporates both the engineered and natural barriers into its safety concept. The safety of the BDS requires confidence in the ability of the engineered barriers on the host environmental conditions to provide containment for the disused sources for a sufficient length of time. The results obtained from the scoping tool indicated that the dose limit was exceeded which showed that the containment provided by the engineered barriers was not sufficient to ensure safety of the disposal system for the specified environmental conditions and radionuclides inventory. Detailed modelling was performed with an AMBER model to evaluate the containment provided by the engineered barriers and the geosphere with some identified scenarios. The AMBER model results showed that the calculated peak dose from any of the disposed radionuclides for the identified scenarios was below the dose constraint of 0.3 mSv/y. The peak doses occurred around 2000–1000000 years. The peak doses were seen to be mainly derived from Ra-266 and Am-241 and/or their daughters. The disused sources could be disposed of safely in the disposal system either in an oxidizing or reducing fractured/porous flow environment without posing any significant radiological threat to humans and the environment.

Pre-licensure nursing students' experiences of psychological safety: A longitudinal qualitative study

BackgroundPrevious studies have explored the concept of psychological safety among pre-licensure nursing students; however, the literature is notably sparse on personal descriptions of pre-licensure nursing students' experiences of psychological safety in clinical settings. Individual descriptions of psychological safety will provide added insight and understanding about the elements that shape psychological safety in pre-licensure nursing students. AimThis research aimed to explore pre-licensure nursing students' experiences of psychological safety during clinical rotations and how these experiences change over time. DesignA longitudinal, qualitative, descriptive design was used for this study. SettingsParticipants were recruited from a nursing program in the Mountain West region. ParticipantsFifty-four students from three cohorts were enrolled in the study at the time of this data collection and analysis. MethodsEach participant completed a semi-structured telephone interview after finishing their first academic term involving a clinical rotation. Participants completed additional interviews after each subsequent semester. Individual waves of data were analyzed using thematic analysis, and multiple waves of data were analyzed using a simplified trajectory approach. ResultsFive themes emerged from the data: “Who I Am,” “Where I Am,” “Who I Am With,” “Responding in the Moment,” and “Anticipating the Future.” ConclusionsThe psychological safety of pre-licensure nursing students in clinical settings is fundamental to their learning and future practice within the nursing profession. The development of psychological safety is dynamic and multifaceted. It is interpersonal but also shaped by organizational factors. Any one person can make an outsized difference in a student's experience. Understanding these themes can help clinical preceptors and nursing faculty understand and better fulfill their respective roles in fostering psychological safety in clinical settings. Additional insights are expected as the longitudinal study continues.

Психологическая безопасность образовательной среды: становление направления и перспективы развития

<p style="text-align: justify;">Psychological problems of safety in the modern world have acquired an extremely high relevance due to the growing spectrum of threats present in the socio-cultural environment. Research on the problems of psychological safety of the educational environment and its subjects is one of the areas of achieving the goal set by the decree of President V. V. Putin on the national development goals of Russia until 2030. The purpose of this publication is to analyze the history, current state and prospects for the development of this area in educational psychology and other areas of psychological research. Research design. Research in this area began at the end of the 20th century and is actively continuing today. In 2003, we developed and defended the concept of psychological safety of the educational environment, assessment methods and creation technologies, which still serve as a guide for new theoretical and practical developments. Results. Based on the analysis of scientific literature, we argue that it is a safe educational environment that maintains the state of human psychological safety. Safety means the presence of certain conditions necessary for life, development and activity. The educational environment is a set of conditions in which the formation and development of a person occurs throughout their entire life. A modern student interacts with many social environments: family, street, media environment, Internet environment, educational environment of a school and additional education organizations, etc.</p>

Conceptual Model for Managing Sources of Danger in the Event of an Earthquake

Safety is defined as a state in which human activities are conducted in such a way that the realization of potential dangers is excluded with a certain probability. However, there is an established axiom: all human activities inherently carry some degree of danger. The criterion for assessing this danger is risk, which provides a quantitative measure of potential threats. Experience has shown that the previous concept of safety, which sought to eliminate all risks entirely (known as the "zero risk" concept), is not practical. Today, the prevailing safety approach is the concept of justified risk—the idea that certain levels of risk are deemed acceptable, based on current economic capabilities and social conditions, for the average citizen. This study presents the development of a conceptual model—a model of communication channels—created through system analysis. This model captures the dynamics of information flows regarding the status of danger sources within a potential earthquake zone. The conceptual model is composed of functional operators: B1, B2, B3, B4, B5, B6, and B7. One key area of this research is the mathematical modeling of emergencies and the forecasting of their potential consequences. Such modeling is crucial for enhancing the effectiveness of protective measures and improving disaster response strategies.

Identifying design criteria for implementing inherent safety in chemical process industries part 2: Design mechanism

AbstractInherent safety concepts are common knowledge today, but accidents with similar characteristics do recur. Research on accident causes found that design errors, especially equipment failure, contribute the highest percentage of accidents. The development of inherent safety tools has been increasing at a positive pace, but only a small number of these tools are applicable to equipment design. Ample amounts of inherent safety tools are only suitable to be used at the early design stage. This amplifies the fact that inherent safety tools are still conceptual (e.g., change process routes, change safer materials). This is in contrast to the circumstances, where tools are expected to reinforce the inherent safety of equipment. The objective of this research is to identify design mechanism that can help trigger design thinking for implementation of inherent safety in the chemical process industry. To identify such a design mechanism, 526 cases were collected, and knowledge of the mechanism was extracted from design changes and presented in this research paper. The mechanisms were classified according to equipment and inherent safety keywords. The significant design mechanisms from the overall summation were listed (turbulence, change heat transfer fluid, continuous removal, large surface area, corrosion resistance, seamless joint, thin film, dividing wall, on demand, and double wall).

Role of artificial intelligence in transmission line protection: A review of three decades of research

The optimal functioning of the power system is crucially dependent upon the sound protection of its major stakeholder, i.e., the transmission line, as it is prone to fault. To maintain the integrity of the power system and protect costly power system equipment, protective relaying is necessary to provide a steady and affordable supply of electricity. Relays recognize, classify, and identify transmission line faults using input signals of voltage and current. Many artificial intelligent methods based on Expert Systems, Artificial Neural Networks, Fuzzy Logic, Support Vector Machines, Wavelet-based systems, and deep learning techniques are being investigated to improve modern digital relays’ consistency, speed, and accuracy. This paper is a comprehensive and all-inclusive survey that reviews and incorporates Phasor Measurement Unit (PMU) and Global Positioning System (GPS) approaches together with all of these intelligent transmission line safety strategies and concepts. Initial investigators will benefit from this study by being able to examine, evaluate, and analyze a variety of approaches with references for all relevant contributions.

'I Think the First Priority is Physically Safe First, Before You Can Actually Get Psychologically Safe': Staff Perspectives on Psychological Safety in Inpatient Mental Health Settings.

While the concept of psychological safety has been gaining momentum, research concerning psychological safety in inpatient mental health wards is lacking. To investigate how psychological safety is conceptualised by healthcare staff in inpatient mental health units, and what barriers and facilitators exist. Reflexive Thematic Analysis was used to analyse 12 interviews. Participants conceptualised psychological safety as feeling safe from physical harm, being able to develop meaningful relationships and feeling valued at work. Participants often did not feel physically safe at work, which led them to feel psychologically unsafe. Barriers to psychological safety were reliance on agency workers, punitive management approaches and the inherent risk in working with mental health inpatients. Facilitators included appropriate staffing ratios and skill mix, being able to form meaningful relationships and having access to support. The emphasis on the physical safety element within psychological safety means that existing definitions of psychological safety require extension for the mental healthcare context. However, large-scale research is needed to further understand experiences of psychological safety in this group. A better understanding of the dimensions of psychological safety in inpatient mental health settings could support the development of tools to investigate psychological safety interventions. Organisations could support psychological safety through regular staff supervision and improved staffing ratios and skill mix.

Tank pool fire domino effect prevention by inherently safer layout planning: A techno-economic analytical index

Tank pool fire domino effects, represented by their capacities of accident consequence escalation and extensive damages, present substantial safety challenges within chemical storage systems. In this work, the inherent safety concept is introduced to proactively address these challenges while ensuring cost-effectiveness. Accordingly, a dedicated novel metric called Inherent Safety & Economic Risk Index (IS&ERI) is proposed to make safety and cost trade-offs for indicating the risk levels of various tank farm layout options. To develop the IS&ERI, the Dow's loss estimate procedure is adapted for representing the economic implications, and the Bayesian Networks are employed for indicating the failure probabilities of target units considering the synergistic effects of multiple pool fires. Two improved graph theory metrics are presented to determine the root nodes of the Bayesian Networks. For demonstrating the proposed IS&ERI, a case study is conducted and the results show that the IS&ERI of 4 tank farm layout options are 0.2991, 0.3120, 0.3525, and 0.2285, implying that Option 4 is the best layout with the lowest potential loss in case of the pool fire domino effects. As the key research contribution, the IS&ERI is presented and it can be used as a useful tool to compare and select the best tank farm layout option to eliminate or significantly reduce the knock-on effects of tank pool fires at their sources.

The Risks Career Game is presented as an innovative solution to address deficiencies in the teaching and learning process of occupational health and safety, and is considered to have the potential to revolutionize the way this subject is taught and learned. The tool is adaptable to virtual and face-to-face environments and is useful for subjects such as industrial engineering, human talent, and occupational health.

Safety amid the scalpels: creating psychological safety in the operating room.

We briefly review the concept of psychological safety and discuss the actions that can create it in the anesthesiologist's work environment. The interest in psychological safety has grown in popularity since the publication of Amy Edmondson's book The Fearless Organization in 2018. While the concept and its benefits are described in the healthcare literature, the specific actions necessary to create it are often not. To ensure patient safety, we want members of the teams we lead to be comfortable sharing emerging problems that they see before we become aware of them. As educators, we want trainees to approach us when they do not understand something and openly participate and contribute without the fear of how others will perceive them. These scenarios require an environment of psychological safety - the ability to ask for help, admit mistakes, and be respectfully forthright with unpopular beliefs without the fear of being ostracized or ignored. Methods for creating an environment of psychological safety will be discussed.

Research on energy consumption evaluation and energy-saving design of cranes in service based on structure-mechanism coupling

Aiming at the problem that the life cycle energy consumption index of hoisting machinery is difficult to be objectively quantified, a crane energy consumption evaluation calculation method based on the working cycle of the service period is proposed, the typical service working mode of the crane is analyzed, and the working cycle process of the mechanism is clarified. On this basis, the stress cycle characteristics of the crane structure during the service period are determined based on the coupling relationship between the mechanism and the structure, which lays the foundation for accurately evaluating the life index of the crane. According to the relationship between the load rate and effective power of each mechanism during the service period of the crane, the calculation method for the evaluation and calculation of the structure energy consumption during the service period of the crane is studied. Finally, the crane is designed based on the concept of absolute service safety, and an optimal design model of the main girder structure of the crane with the goal of the lowest energy consumption in service is established. Using the research method of this paper to study a certain type of bridge crane, the energy consumption of the hoisting machinery during its service period is not only related to the accumulation of the operating characteristics of the mechanism but also related to the characteristic parameters such as the structure self-weight. The comprehensive evaluation of energy consumption provides an effective quantitative method and a reliable green design theory for crane design.

Theoretical and experimental considerations regarding the airbag system operation

Abstract The concept of Passive Safety aims to reduce the harmful effects on vehicle occupants and pedestrians in the event of an accident. Intelligent car bodies and restraint systems have been designed. Thus, side, front, knee and head airbag systems have been introduced, as well as pre-strained seat belts and force limiters. The objectives of car manufacturers are not only to reduce injuries that can cause death, but also a significant reduction of those that can result in permanent damage such as a whiplash. Advanced airbag systems are currently introduced, which offer protection to the occupants at the knees, torso, hips and abdomen. The topic proposed in the paper concerns both theoretical research on the operation of passive security systems, respectively the airbag system, and experimental research. Regarding the theoretical research, this paper proposes a virtual prototyping method by means of the LS Dyna software package of the airbag system functioning in order to protect the driver in the event of a frontal collision. For the analysis of the airbag system functioning, a complex assembly which contains of a dummy, seat, steering wheel, passive safety systems was used. For the experimental research a stand was designed for the analysis and testing of the airbag system, which has the role to protect the driver in the event of a frontal collision of the vehicle. In order to carry out the experimental tests, it was proposed to create a sledge type stand, which simulates frontal collisions.

Different concepts of neighborhood safety and child internalizing and externalizing behaviors.

Neighborhood safety is defined inconsistently across epidemiologic studies - a conceptual problem that results in incomparable measurements, hampering the design of health interventions. Using child behavior problems (measured via the Child Behavior Checklist) as the outcome of interest, this study directly compared four measures of neighborhood safety: two of experienced safety and two of perceived safety, with each one measured at family and community levels. These included children's direct experience of harm, parental perceptions, community crime statistics, and community perceptions. In a sample of 3291 ten-year-olds from the Generation R cohort (living in municipal Rotterdam, Netherlands, 2013), all four measures were correlated (χ2 ≥ 9.2, P < 0.002 in pairwise chi-square comparisons), but ultimately identified different levels of risk for behavioral health. Direct experiences of harm, parental perceptions, and community crime statistics were all associated with increased child internalizing behaviors (β = 3.12, β = 2.10, and β = 1.77, respectively), while only experiences of harm and parental perceptions were associated with increased externalizing behaviors (β = 2.75 and β = 1.31, respectively). These results provide novel evidence that the conceptual distinctions underlying different measures of neighborhood safety are meaningful for child mental health and should be considered in intervention design.

Integral system safety for machine learning in the public sector: An empirical account

This paper introduces systems theory and system safety concepts to ongoing academic debates about the safety of Machine Learning (ML) systems in the public sector. In particular, we analyze the risk factors of ML systems and their respective institutional context, which impact the ability to control such systems. We use interview data to abductively show what risk factors of such systems are present in public professionals' perceptions and what factors are expected based on systems theory but are missing. Based on the hypothesis that ML systems are best addressed with a systems theory lens, we argue that the missing factors deserve greater attention in ongoing efforts to address ML systems safety. These factors include the explication of safety goals and constraints, the inclusion of systemic factors in system design, the development of safety control structures, and the tendency of ML systems to migrate towards higher risk. Our observations support the hypothesis that ML systems can be best regarded through a systems theory lens. Therefore, we conclude that system safety concepts can be useful aids for policymakers who aim to improve ML system safety.
