Neuroethical considerations and attitudes about neurostimulation as a fatigue countermeasure among emergency responders

IntroductionFirst responders play a pivotal role in ensuring the wellbeing of individuals during critical situations. The demanding nature of their work exposes them to prolonged shifts and unpredictable situations, leading to elevated fatigue levels. Modern countermeasures to fatigue do not provide the best results. This study evaluates the acceptance and ethical considerations of a novel fatigue countermeasure using transcranial Direct Current Stimulation (tDCS) for fire and emergency medical services (EMS) personnel.MethodsTo better understand first responders' perceptions and ethical concerns about this novel fatigue countermeasure in their work, we conducted semi-structured interviews with first responders (N = 20). Interviews were transcribed into text and analyzed using qualitative content analysis.ResultsOver half of responders (59%) were interested, but over a third had a cautionary stand. Half of the participants seemed to have positive views regarding acceptability; a few were more cautionary or hesitant. A main area of consideration was user control (75%), with the majority wanting to retain some control over when or whether to accept the stimulation. Just above half of the participants (64%) mentioned privacy concerns. Another relevant consideration, raised by 50% of participants, was safety and the potential impact of stimulation (e.g., side effects, long-term effects). Overall, participants thought they needed to understand the system better and agreed that more education and training would be required to make people more willing to use it.DiscussionOur exploration into combating fatigue among first responders through tDCS has revealed promising initial reactions from the responder community. Findings from this study lay the groundwork for a promising solution, while still in a nascent design stage, to improve the effectiveness and resilience of first responders in fatiguing shifts and critical situations.

Assessment of Muscle Synergies in Chronic Ankle Instability Patients During Unanticipated and Anticipated Landing

Ankle sprains are a common injury among athletes and the general population, with chronic ankle instability (CAI) being a frequent complication. CAI patients often display altered neuromuscular control adaptations. This study analyzed muscle synergy patterns in 20 CAI patients during anticipated and unanticipated landing tasks to understand their neuromuscular adaptation strategies. Using Nesterov non-negative matrix factorization and K-means clustering, the study identified distinct muscle activation patterns. Results indicated that during unanticipated landings, the gluteus maximus and vastus lateralis showed increased activation weight, while the medial gastrocnemius was more active in anticipated landings. This study highlights that CAI patients display unique muscle synergy patterns during unanticipated landings, relying more on proximal muscles such as the gluteus maximus and vastus lateralis. This adaptation reflects the proximal muscle strategy to enhance stability and compensate for impaired ankle function in unpredictable situations.

Economic Design of Quality control by Using Triangular Fuzzy Number with Alpha Cut

Manufacturers today prioritize increasing output quality while reducing per-unit costs to remain competitive. Statistical Process Control (SPC) is a useful tool for boosting quality and output. However, decision-makers in industries face difficulties in cost and quality control due to uncertainty in data. Fuzziness can be applied to uncertain data to manage the economic design of a control chart, allowing for better control over the control chart's economic design. This study seeks to enhance the economic design of X control charts by using fuzzy set theory, specifically utilizing triangular fuzzy numbers for cost parameters and the signed distance approach for defuzzification. The objective is to enhance the adaptability of these charts in unpredictable situations. The proposed model enables the incorporation of cost parameters inside a fuzzy framework, with the objective of minimizing the control chart while adhering to the permissible limit. The applicability and improved accuracy of the model in optimizing control chart parameters for a glass bottle production process are exemplified by an effective illustration. This study highlights the need of integrating fuzzy logic into SPC. It suggests a technique that improves the cost-effectiveness and operational effectiveness of control charts in situations when data is uncertain and imprecise. .

Marine Operations in the Norwegian Sea and the Ice-Free Part of the Barents Sea with Emphasis on Polar Low Pressures

The Arctic Seas are attractive for shipping, fisheries, and other marine activities due to the abundant resources of the Arctic. The shrinking ice cover allows for the opening of activities in increasingly larger areas of the Arctic. This paper evaluates the possibility of executing all-year complex marine activities, here termed “marine operations”, in the Norwegian Sea and the ice-free part of the Barents Sea. The approach used during the preparation of this review paper is to identify constraints to marine operations so users can be aware of the limitations of performing such operations. The weather conditions in the Norwegian Sea and the Barents Sea are well known, and these seas are considered representative of ice-free or partly ice-free Arctic Seas with considerable marine activities. Similar conditions could be expected for other Arctic Seas during periods without ice cover. Marine operations require safe and stable working conditions for several days. The characteristics of marine operations are discussed, and the particulars of the Norwegian Sea and the Barents Sea physical environments are highlighted. Emphasis is on the wind and wave conditions in unpredictable polar low-pressure situations. Furthermore, situations with fog are discussed. The large uncertainties in forecasting the initiation and the tracks of polar lows represent the main concern for executing marine operations all year. Improvements in forecasting the occurrence and the path of polar lows would extend the weather window when marine operations could be carried out. Discussions of the potential for similar conditions in the wider Arctic Seas during ice-free periods are presented.

Comparative Analysis of the Physical, Tactical, Emotional, and Mood Characteristics of Under-13 Soccer Players by Performance Level.

Background and Objectives: Soccer is a sport characterized by various unpredictable situations in which physical abilities are associated with athletic performance. There are several capabilities that young soccer players must develop to adapt to the needs of the competition. This study analyzes the physical characteristics, tactical knowledge, emotional intelligence, and mood states of youth soccer players at different competitive levels. Materials and Methods: The sample consisted of 36 male soccer players with an average age of 12.65 ± 0.48 years, weight of 44.92 ± 7.49 kg, and height of 157.2 ± 0.08 cm. A cross-sectional correlational study design was selected. Inferential analysis was conducted via the RV coefficient to assess relationships between groups. Two-sample tests (Student's t test or the Mann-Whitney U test) were used to assess the distribution of the samples. Standardized mean differences (i.e., Cohen's d) were calculated as effect sizes. Results: For the yo-yo intermittent endurance test level 1, the Premier category showed higher speed (p = 0.01, d = 0.40) and superior estimated VO2max (p = 0.01, d = -0.91). The statistically significant variables included the hamstring strength exercise of the hamstrings for the angle of rupture (p = 0.04, d = -0.04, d = -0.72), the COD-Timer 5-0-5 for contact time-5-0-5 (ms) (p = 0.04, d = 0.69) and 10 m-5-0-5 (s) (p = 0.02, d = 0.79), tactical knowledge of in-game performance (p = 0.01, d = -1.19), support level (p = 0.01, d = -1.27), decision-making ability (p = 0.01, d = 0.59), melancholy (p = 0.01, d = 0.59), confusion (p = 0.01, d = 0.56), and emotional intelligence (p = 0.04, d = 0.77). The Premier category presented slightly higher averages than did category A. In the assessment of running-based anaerobic sprint test power (p < 0.05, d = 0.83) and mood states (p < 0.05, d = 0.59), players in category A presented higher results. Conclusions: The performance capacity of youth soccer players encompasses a multidimensional complexity that includes physical, tactical, emotional, and psychological aspects, which vary among players of the same age.

Decreased proprioception is associated with inferior postural control during unplanned landing in individuals with chronic ankle instability

ABSTRACT Poor postural control during jump landing may increase ankle sprain incidences among people with chronic ankle instability (CAI). The effects of anticipation on it and its relationship with proprioception need further examination. Fifteen participants with CAI and 15 healthy controls were recruited to perform single-leg jump landings when knowing the landing side before (planned) or after (unplanned) take-off respectively, along with a step-down proprioception test differentiating four inclination platforms (inverted 12°, 14°, 16° and 18°). Ground reaction force data (peak force, loading rate and time of stabilisation) during landings and proprioception scores were collected and analysed. The CAI group exhibited a higher loading rate (59.6 ± 7.6 vs 49.4 ± 6.7 N/kg*seconds, p = 0.011) and longer medial-lateral time to stabilisation (4.82 ± 0.69 vs 4.11 ± 0.47 seconds, p = 0.023) compared to the control group during an unplanned landing. Furthermore, the above variables were negatively correlated with the step-down proprioception score only in the unplanned condition but not in the planned condition. CAI participants had inferior medial-lateral time-to-stabilisation and loading attenuation during unplanned jump landing than healthy controls, which were associated with decreased proprioception, highlighting the importance of addressing proprioception to improve balance control during unpredictable landing situations.

Agile Bureaucracy in the Digital Age

In providing public services, the bureaucracy faces challenges of disruption, rapid technological developments, and demands for fast, efficient, and flexible services while it struggles with procedural problems and hierarchy. After bureaucratic reform efforts in Indonesia have been conducted for many years, the apparatus readiness in the local government context to provide fast and responsive services in the digitalisation era and unpredictable situations like pandemics is unexamined. While researchers focus on the use of agile government concept in local government, the assessment of adaptive governance and its implications, and the use of information technology communication in the public sector, in this paper, the authors assess agile bureaucracy in service delivery through digital public services. The results show the software maturity in local bureaus, characterised by their ability to understand user needs for digitalised service and qualified infrastructure tools to support governance. However, agencies face the challenge of weak collaboration with minimal coordination among departments and weak responsibility and adaptability to hinder digital service delivery processes. This article highlights that in adopting the agile concept, bureaucracy requires technological support and the leaders' strong commitment. Moreover, the bureaucracy needs to build a broad and coordinated partnership ecosystem, and the main points are adapting quickly and responsively to problems.

Анализ теории и практики адаптации обучающихся к интерактивным технологиям обучения

The article provides a retrospective analysis of various approaches to the adaptation of students in an interactive educational environment. The characteristics of each of the analyzed approaches highlight the specifics of students' adaptation to the conditions of an interactive learning environment. The purpose of the article is to analyze the theory and practice of students' adaptation to an interactive educational environment. A comparative analysis of various scientific approaches to the adaptation of students to the educational process has allowed us to define pedagogical processes as synergetic systems in which unstable, unexpected and unpredictable situations are constantly created that require an adequate operational response from students. Consideration of pedagogical processes as synergetic systems leads to the need to use interactive educational technologies in the educational process. In an interactive educational environment, adaptation does not manifest itself in a traditional academic form, but takes the form of preadaptation, which requires students to quickly search, build and regulate their attitude and behavior, adequately changing the conditions of the educational environment. Based on the analysis of the dynamics of the development of interactive learning technologies in the study, meaning-creating educational technologies have been experimentally developed and substantiated, allowing creating conditions in the educational process for the openness of thoughts, ideas and meanings of students and the phenomena studied and knowledge about them. The educational technologies proposed in the article are a new direction in the development of an interactive educational environment, and their use in educational practice can significantly increase the adaptability of students to the educational environment.

Competence-based Educational Design Model for Medical Sciences Based on the Community of Inquiry

Introduction: Achieving competence as the main goal in medical education requires a dynamic and active learning process that includes the characteristics of a community of inquiry framework. This theoretical framework provides an overall and coherent structure of an interactive educational experience with a focus on the learning process. Therefore, the purpose of this research was to develop a competency-oriented educational model for medical sciences based on the framework of the community of inquiry. Methods: This was a qualitative and quantitative research. The qualitative part was conducted using qualitative content analysis of documents and focus group discussions, while the quantitative part involved internal validation of the educational design model through a descriptive survey method (based on experts' opinions) and a researcher-made questionnaire. The sampling method was purposeful, focusing on specific or unique cases continuing until theoretical saturation was reached. Results: Using qualitative content analysis (36 documents, 33 articles, and three books) and focus group discussions (with the participation of 14 experts in medical education), the dimensions of competence, principles of competency-based medical education, and principles of inquiry community were identified. Based on theoretical foundations, these were categorized into three domains: affective, cognitive-skills, and metacognitive, along with their subcategories. The alignment of these dimensions led to the formation of a competency-based medical education model, grounded in the inquiry community framework. Internal validation of the developed model was conducted using a researcher-made questionnaire and the participation of 14 experts in educational technology and medical education. According to the specialists' opinions, the developed model achieved a relatively high internal validity (T=14.52, P&lt;0.0001). Conclusion: In this study, the competency-based educational design model for medical education, based on the inquiry community, exhibited appropriate design and organization, flexibility, and adaptability to individual learning needs, even in unpredictable situations within medical education. Its design and organization can be continuously refined and improved throughout the educational experience. Given that it achieved a relatively good internal validity according to the opinions of specialists in medical education and educational technology, it can be introduced as a suitable model in the field of competency-based medical education.

An evaluation of the adaptive performance of architects in project teams in Ghana using fuzzy approach

PurposeThe adaptive performance of architects as a key professional in project delivery teams has become important for developing strategies, skills and cognitive behaviours for sustainability of working systems. However, the understanding and knowledge of adaptive performance of architects is lacking in the current literature. Thus, this study fills this gap by primarily assessing the adaptive performance of architects in project teams in project delivery.Design/methodology/approachBy adopting the widely used eight-dimension attributes of adaptive performance, a questionnaire survey was conducted among team participants and stakeholders who directly or indirectly work on projects with architects in the public and private sectors project delivery supply chain in Ghana. A total of 42 responses were subsequently used in a fuzzy set theory analysis being facilitated by a set of linguistic terms.FindingsFrom the assessment, the overall adaptive performance of architects from the eight-dimension attributes emerged to be fairly high. Additionally, the architects’ performance in the individual eight-dimensions showed varied results. High performance was registered in architects’ ability to handling work stress and cultural adaptability. Also, architects demonstrated a fairly high performance in dealing with uncertain or unpredictable work situations. However, in the cases of learning work tasks, technologies and procedures, interpersonal adaptability and handling crisis and emergency situations, architects were deemed to have low and fairly low adaptive performance among project teams.Originality/valueGiven the vagueness and complexities in understanding adaptability among teams and its assessment, through the use of fuzzy set theory based on a suitable set of linguistics terms, the study presents a novel understanding of the level of architects’ adaptive performance in project teams in project delivery. The findings are extremely useful in helping architects adapt and cope with changing competitive work environment by developing the right cognitive behaviours for task functions and organizational roles, disruptions and aiding their ability to self-regulate.

An improved hierarchical deep reinforcement learning algorithm for multi-intelligent vehicle lane change

Lane change is a pivotal technology in autonomous driving, playing a significant role in improving traffic conditions. The control task of lane change becomes exceptionally complex for coordination of multiple intelligent vehicles, especially in unpredictable situations. To address this issue, the paper proposes a novel multi-intelligent vehicle lane change method (MVLC) based on Deep Reinforcement Learning (DRL). The MVLC features a hierarchical framework that includes a lower-layer lane change controller and an upper-layer reinforcement learning decision-making method. In the lower layer, a lane change controller is designed to execute motion control for a single vehicle, consisting of a lateral controller utilizing dueling double deep Q-network to make lane change decision and a longitudinal controller that employs Intelligent Driver Model (IDM) to follow the preceding vehicle. In the upper layer, a model-free DRL method is used for simultaneous control of multiple intelligent vehicles. To learn the optimal policy, a comprehensive reward function is designed. Finally, experiments are conducted in mixed traffic to valid the effectiveness of the proposed method. Results show that MVLC achieves secure and timely lane changes for multiple vehicles. Therefore, the method is expected to have significant potential for improving overall traffic efficiency and mitigating traffic congestion.

Autistic re-creation: Live action role-play as a safe and brave space for social learning

Live action role-play (larp) is an improvised and embodied form of storytelling that develops through co-creation. While autistic individuals generally dislike unpredictable situations and social interaction in larger groups, anecdotal reports suggest that they often are found in the larping community. Through interviews with 10 autistic, experienced adult larpers, this study investigates larp as a scene for social learning. The examination focuses on the attraction of larps; what the participants learn about social interaction through larping; and how such insights transfer to everyday life. From a cognitive point of view, larping comes through as an optimal autistic space where players feel safe enough to dare push their social boundaries, which conceivably contributes to the formation of more precise social predictions since experimentation and mistakes facilitate embodied learning. From the participants’ point of view, larping improved their understanding of social nuances, which in turn increased social confidence and well-being in everyday life.

Understanding Instant Social Control of Shared Devices in Public Spaces: A Field Trial

Public spaces are created for the convenience of visitors, but frequently, their operation does not match individual visitors' needs. We propose instant social control as a new approach for controlling devices deployed in public spaces, envisioning the democratic and inclusive operation of the spaces. It is an approach to embrace individuals in the dynamic and unpredictable situations of public spaces, providing them with a powerful tool of immediate engagement and reflection. This research explores the use of instant social control, focusing on cases where discrepancies and conflicts arise among visitors' preferences for operating public devices. We conducted a field trial by deploying a technology probe to two real-world public spaces: a university auditorium, and a cafeteria. We collected usage logs and surveyed the users' experience with this new way of device control. We further investigated their experience through in-depth interviews with participants. Our field trial revealed a rich set of findings including voting strategies, exploratory device control patterns, users' attempts to communicate with other visitors, considerations of other visitors' discomfort, and acceptance and usefulness of instant social control of public devices.

Peripersonal space: why so last-second?

A vast range of neurophysiological, neuropsychological and behavioural results in monkeys and humans have shown that the immediate surroundings of the body, also known as peripersonal space (PPS), are processed in a unique way. Three roles have been ascribed to PPS mechanisms: to react to threats, to avoid obstacles and to act on objects. However, in many circumstances, one does not wait for objects or agents to enter PPS to plan these behaviours. Typically, one has more chances to survive if one starts running away from the lion when one sees it in the distance than if it is a few steps away. PPS makes sense in shortsighted creatures but we are not such creatures. The crucial question is thus twofold: (i) why are these adaptive processes triggered only at the last second or even milliseconds? And (ii) what is their exact contribution, especially for defensive and navigational behaviours? Here, we propose that PPS mechanisms correspond to a plan B, useful in unpredictable situations or when other anticipatory mechanisms have failed. Furthermore, we argue that there are energetic, cognitive and behavioural costs to PPS mechanisms, which explain why this plan B is triggered only at the last second. This article is part of the theme issue 'Minds in movement: embodied cognition in the age of artificial intelligence'.

GAMBARAN GRIT PADA MAHASISWA PENDIDIKAN PROFESI DOKTER PERGURUAN TINGGI NEGERI (PTN) DAN PERGURUAN TINGGI SWASTA DI INDONESIA

Medical professional students have responsibilities, such as facing unpredictable real situations, large numbers of patients, uncooperative patients, and difficulties with the diseases they treat. The number of responsibilities can cause emotional exhaustion, stress, and burnout for medical students. To overcome this, medical students need a “Grit”. Grit is the desire of oneself to achieve long-term goals accompanied by high perseverance and consistency of interest in these goals. This study uses a quantitative approach with a descriptive research design. The population of this study were medical professional education students in Indonesia. This study used a non-probability sampling technique with convenience sampling. The sample size used was 120 participants. The results of this study are professional medical education students have a high grit score (91.67%). Based on the dimensions of consistency of interest and perseverance of effort, the majority of medical professional students have high scores on both dimensions. In this study, the most selected internal factor was "Purpose" (27.2%), while the external factor was "Parenting" (36.67%). A recommendation for future research to conduct mixed method research to examine the topic of grit and its factors more elaborately in order to determine its influence on individuals.

Formulation Optimization and Characterization of Solid Lipid Nanoparticles of Apixaban.

Unpredictable situations such as clotting of blood, deep vein thrombosis, and pulmonary embolism arise in the body, which is the leading cause of mortality. Such conditions generally arise after surgery as well as after treatment with oral anticoagulant agents. Apixaban is a novel oral anticoagulant widely recommended for the prevention and treatment of strokes and blood clots suffering from nonvalvular atrial fibrillation by suppressing factor Xa. Apixaban has a log P of 2.71 with poor solubility and reported maximum bioavailability of approximately 50%. Hence, the current research mainly focused on the improvement of solubility, bioavailability, and therapeutic efficacy of Apixaban via solid lipid nanoparticles (SLN). The SLN was developed using the hot-homogenization method using a high-pressure homogenizer. The drug-lipid compatibility study was assessed by the FTIR, and the thermal analysis was performed using differential scanning calorimetry (DSC). During the scrutiny of lipids, the highest solubility of Apixaban was estimated in the glyceryl monostearate, hence selected for the formulation. Moreover, the colloidal solution was stabilized by the polyethylene glycol 200. The Design of Expert software (Version 13, Stat-Ease) was implemented for the optimization analysis by considering the 3-independent factors and 2-dependent parameters. The Patents on the SLN are Indian 202321053691, U.S. Patent, 10,973,798B2, U.S. Patent, U.S. Patent 2021/0069121A1, U.S. Patent 2022/0151945A1. Box-Behnken design was applied along with ANOVA, which showed a p-value less than 0.05 for the dependent parameters such as particle size and entrapment efficiency (p-value: 0.0476 and 0.0379). The optimized batch F10 showed a particle size of 167.1 nm, -19.5 mV zeta potential, and an entrapment efficiency of 87.32%. The optimized batch F10 was lyophilized and analyzed by Scanning electron microscopy (SEM), which showed a particle size of 130 nm. The solid powder was filled into the capsule for oral delivery. The marked improvement in solubility and bioavailability was achieved with F10- loaded Apixaban via Solid lipid nanoparticles. Moreover, the sustained released profile also minimizes the unseen complications that occur due to the clotting of blood.

Factor Influencing Purchase Intention among Indonesian towards Yogyakarta Fashion Product via Digital Marketing

To be able to sustain in this unpredictable global situation, MSMEs in Yogyakarta must expand their sales via digital to reach more consumers. The purpose of this study was to evaluate measures and explore factors that influenced the purchase intention of local people towards Yogyakarta's local products through digital marketing. This study was guided by theory planned behaviour model approach and digital marketing mix theory. Data were collected online using Google Forms, and the snowball sampling technique was used to reach the sample. Results from the pilot test demonstrated that both adapted and self-developed measures were reliable that demonstrated an overall Cronbach alpha value of .97. The data analysis technique used Exploratory Factor Analysis (EFA). The research results showed that EFA had identified six factors (6). Findings from the analysis confirmed that the scales were reliable and validated the influence of purchase intention of local people towards Yogyakarta's local products through digital marketing. The measures enable to be applied in examining the influence of theory of planned behavior and digital marketing mix theory on purchase intention on Yogyakarta goods. This would help to generalize the data in wider scope of market such as in Indonesia.

Multi-manned disassembly line balancing problems for retired power batteries based on hyper-heuristic reinforcement

Considering the complexity and uncertainty of retired power batteries, worker disassembly can reduce the cost and increase the flexibility of the disassembly process. To address the problem of considerable waste products, we investigate a multi-manned disassembly line balancing problem with different work modes (MWM-DLBP). In addition, we explore the impact of variability in penalizing factors (earliness and tardiness) on costs when products of different scales need to be disassembled. Given the NP-hard of the problem and unpredictable situations, we propose a reinforcement learning-based Hyper-Heuristics (RLHHs) algorithm to solve the practical issues. A Markov model is constructed to generate a sequence of low-level metaheuristic algorithms, and a multi-armed bandit (MAB) method is designed to tune different critical parameters intelligently. The superiority of RLHHs is verified by comparing the optimization results with other algorithms. Further, results reveal that the new disassembly scheme can save an average cost of 9.81% compared to the original system design. Finally, we provide manufacturers with the specific workforce planning and working mode for disassembly tasks under different scenarios.

Experiences of Nursing Students Regarding Challenges and Support for Resilience during Clinical Education: A Qualitative Study.

Nursing students require resilience to navigate the complexities of clinical practice. This characteristic is essential for managing demanding workloads, unpredictable patient situations, and emotional stressors while maintaining performance and well-being. Fostering resilience helps students develop the capacity to adapt to adversity, overcome setbacks, and remain committed to providing high-quality patient care. This qualitative study explores the challenges and supports influencing nursing students' resilience during clinical education. Interviews with 28 Thai nursing students revealed two key themes: the "experience of vulnerability" and the "experience of meaningfulness". The sub-themes of vulnerability included "navigating uncertainty", "transcending professional struggles", and "being exposed to diverse encounters". The sub-themes of meaningfulness focused on restoring strength through social interactions and engaging in positive transformation. This study highlights the need for comprehensive support systems that address personal and professional vulnerabilities. Integrating caring theory principles could further enhance resilience by emphasizing compassionate care and fostering student empathy. This suggests that instructors and stakeholders can significantly impact student well-being by creating supportive environments built on collaboration, empathy, and mentorship, all of which are aligned with caring theory.

Optimizing Self Efficacy in High School Students Through Group Counseling with Rational Emotive Behavior Therapy (REBT)

Within the same age group, individuals have very different appearances, abilities, temperaments, interests and attitudes, including physical and mental differences. An educator must understand the individual differences of students to understand the desires, needs and problems of each student. Self-efficacy is self-confidence in carrying out tasks responsibly, considering one's own abilities, planning for the future, and having self-control when experiencing pressure and unpredictable situations. One method of guidance and counseling that can be relied upon to overcome problems faced by students is group counseling, especially Rational Emotive Behavior Therapy (REBT), which offers increased self-efficacy. This research aims to find out self-efficacy in high school students through the Rational Emotive Behavior Therapy (REBT) approach in group counseling. The research results show that self-efficacy has a very significant relationship with family social support and independent learning, adolescent adjustment, desire to learn, mathematics achievement, and communication skills.
