Challenges And Coping Mechanisms of Kindergarten Parents in Modular Distance Learning in Public Schools
Authors: Naquila Jonna Rose
Published: February 2025

This study investigates the challenges and coping mechanisms encountered by kindergarten parents during the transition to modular distance learning in public schools amidst the COVID-19 pandemic in Tagbilaran City, Bohol, Philippines. Utilizing a quantitative descriptive-correlational research design, the study involved 264 parents who facilitated their children's distance learning. A researcher-made questionnaire, validated by experts and demonstrating high internal consistency (Cronbach's Alpha = 0.959 for challenges, 0.952 for coping mechanisms), was employed to collect data. The statistical analyses included descriptive statistics to summarize the data and inferential statistics such as the Mann-Whitney U Test, Chi-Square Test, and Spearman's Rho to explore relationships between variables. Findings revealed significant challenges related to balancing responsibilities, learner motivation, and accessibility. Furthermore, male parents encountered more challenges than female parents. On the other hand, single parents reported more effective coping strategies compared to their partnered counterparts. Despite facing substantial challenges, parents demonstrated resilience through varied coping mechanisms. The study highlights the essential role of parental involvement in their children's education and suggests recommendations for support interventions from educational authorities.

This study shows the relationship between the challenges encountered in blended learning in the key aspects of interaction and motivation, learning materials, and the quality of English communication instruction in relation to oral communication skills such as extemporaneous speaking, storytelling, and oral picture description. The study's primary purpose is to demonstrate how challenges encountered in blended learning affect English communication proficiency. Forty-two respondents officially enrolled in the Bachelor of Secondary Education major in English for the school year 2020-21 at the University of Bohol-Teachers College were randomly sampled with a +/-5% margin error at a 95% interval using a quantitative-correlational modified survey questionnaire. The survey tool underwent face validity using Cronbach's Alpha and pretested to ten respondents who were given thirty minutes to answer. Furthermore, findings revealed no significant relationship between the challenges encountered by the respondents and their oral communication proficiency. Thus, challenges encountered in blended learning did not affect the teaching and learning of oral communication in English. Finally, this recommends that academic administrators and teachers carefully review the English modules to promote an interactive teaching-learning process in English communication. It further recommends that students have a written daily plan to avoid mingling with school and household responsibilities.

To develop key competencies, it is necessary to build learning environments taking into account their dimensions. The learning process is complex, and emotions are one of the extremely important factors. It is worth adding that both learning and emotions are dealt with by researchers from various fields, including: psychology, pedagogy, neurobiology. The authors present the theoretical foundations of learning and the theory of emotions from various perspectives. The article is a review because it presents the results of Polish and foreign research on the importance of emotions in the learning process. As research shows, emotions influence the level of motivation and the results obtained. However, the analysis of research results indicates the need to address this topic, as it is a niche area of research, especially in Poland. Moreover, the importance of emotions in the process of acquiring knowledge and skills should be taken into account and, therefore, the mental well-being of students and teachers should be taken care of.

Authors: Souto Prego Borja , Vilares David , Cabado Lousa Bruno
Published: February 2025

In today's data-driven world, the ability to access and interpret information is crucial for informed decision-making. However, technical complexities in database management often create barriers for non-experts. This paper presents a prototype of a chatbot leveraging large language models (LLMs) to bridge this gap. The chatbot interprets natural language questions about structured databases and translates them into SQL queries, retrieving relevant data and converting results back into natural language. The system was tested with four different LLMs, evaluated by human evaluation on a number of metrics: accuracy, relevance, fluency, completeness, cohesion, and naturalness. The results show the usefulness of the approach and how it can make data interaction more user-friendly by democratizing data access, reducing human workload, and empowering users to focus on strategic tasks.

Published: February 2025

Identifying new white dwarfs (WDs) heavy elements is crucial, as they serve as valuable tools for deducing the chemical characteristics of potential planetary systems accreting material onto their surfaces. To detect metallic WDs, we propose a methodology based on an unsupervised learning technique known as Self-Organizing Maps (SOM). This approach projects a high-dimensional dataset onto a two-dimensional grid, where similar elements are grouped into the same neuron.

Using this method, we uncovered 143 bona fide WD candidates in the Gaia space mission with several metallic lines in their spectra, including Ca, Mg, Na, Li, and K. The precision metrics achieved with our method are comparable to those of recent supervised techniques.

Coronavirus-Pandemie im Zerrspiegel des polnischen Pressewitzes
Authors: Sikorska-Bujnowicz Katarzyna
Published: February 2025

The analysis of the “Tygodniówka” column published on the last page of a weekly magazine “Angora” for the years 2020–2021 made it possible to evaluate the way of presenting an individual and his everyday life during the COVID-19 pandemic in a crooked mirror of cartoon jokes. During one year there is an evident change in attitudes and behaviour of people who have already got used to the pandemic to some extent. Due to the length of the material collected and the most visible change that took place in the way of presenting the mocked events, attitudes and human behaviour in the past year, two specific issues of “Angora” were selected, i.e. 49/2020 and 49/2021. In addition, the examples from the holiday issue 33/2021 have shown how the behaviour of an individual living in constant fear of the coronavirus changes during a vacation. A man tired of the prohibitions and sanitary regime to be in force also seeks opportunities not to follow them for a while. He consciously circumvents restrictions and prohibitions, does not comply with the sanitary regime, which is manifested by the resignation from wearing masks and maintaining social distance. All of this can be found in the jokes of “Tygodniówka”, where mercilessly accurately reflects the pandemic reality, although it’s been showed in the crooked mirror. The person seems to be sure that the coronavirus has magically ceased to be a threat, perhaps even disappeared.
Population Losses in the Wola Area During the Warsaw Uprising 1944. A Review of Research and an Attempt at Balance
Authors: Przeszowski Kazimierz
Published: February 2025

This article reviews the research of Stanisław Płoski and Ewa Śliwińska, Adam Borkiewicz, Hanns von Krannhals, Maria Turlejska, Antoni Przygoński, Joanna Hanson, Maja Motyl and Stanisław Rutkowski, Piotr Gursztyn, Norbert Bączyk and Grzegorz Jasiński and Hubert Kuberski, which indicates that there were between 10,000 and 57,600 victims of the Wola massacre. A comparative analysis of mass executions in Rumbula near Riga, Babyn Yar near Kyiv, and executions carried out as part of the ‘Ertnefest’ operation has shown that the German forces in Wola were sufficient to exterminate even up to approximately 60,000 people. It was also demonstrated that the Wola district covered the area west of Towarowa and Okopowa streets, composed of 14 statistical districts belonging to 7 police districts. The estimated population of Wola in the summer of 1944 was approximately 100,000 people – potential victims of mass executions. The above findings indicate the need to develop a new methodological proposal and conduct further research on the number of population losses in Wola in 1944.

Published: February 2025

The slope is one of the important elements in topography that affects various natural processes and human activities. Slope position can lead to reduced soil fertility due to runoff. This research aims to analyze the comparison of water-stable aggregate on different slope positions which are divided into three, namely between upper slope, middle slope and lower slope. The research method used is descriptive comparative, which is carried out by deliberate sampling on sloping land planted with rubber plants with a depth of 0-20 cm and the same slope of 25-45% and then analyzed in the soil laboratory. Data were analyzed by t-test to determine the comparison of water-stable aggregate different slope positions. The results showed that water-stable aggregate values at different slope positions had significant differences. Water-stable aggregate values in the upper slope tend to be smaller than those in the middle slope and lower slope which are much larger. Slope position, organic-C content, and clay fraction affect water-stable aggregate values

Voluntary and rights-based family planning for women: Observations from a community-based study in southern India
Authors: SG Shruthee , Arasi Senthil , P Seenivasan
Published: February 2025

Background: Family planning programmes globally emphasise voluntarism and rights in contraceptive provision, shifting the focus away from fertility regulation. With the intent of measuring the policy-practice gap, this study aims to determine access to voluntary rights-based family planning services among women of reproductive age.

Methods: Between November 2018 and January 2019, 390 married women aged 18 to 44 years residing in Kanchipuram, Tamil Nadu, were interviewed, after obtaining written informed consent from the participants. Agreement between intended and actual family size and spacing, perceived informed choice and contraceptive coercion during client-provider interaction were the primary outcomes studied. Univariate analysis using Pearson’s or Trend chi square tests and multivariate logistic regression were used to analyse the factors associated with contraceptive coercion; adjusted odds ratios (AOR) with their 95% confidence intervals are reported.

Results: Of the 390 most recent pregnancies, 114 (29%) were found to be unintended. Reported concurrence of intended versus actual family size and spacing among respondents was 76% (118/155) and 42% (121/287), respectively. During interaction with a healthcare provider, only 139 (36%) were offered a choice of two or more modern contraceptives; others were advised either tubectomy (69, 18%) or intrauterine devices (IUD) (50, 13%) as the sole option. In the past five years, 181 (46%) women reported adopting a modern method voluntarily, while 33 (8.5%) were forced and 8 (2.0%) were coerced to use modern contraception. Multivariate analysis revealed that women’s employment status (AOR: 13.1[1.3,127.6], P=0.027), public healthcare facilities (AOR: 18.7 [1.8, 193.2], P=0.014), and long-acting reversible contraception (AOR: 30.5 [8.2, 112.6], P <0.001), IUD in particular, were strongly associated with contraceptive coercion.

Conclusion: Provider bias and coercion to use selective modern methods in a limited contraceptive choice setting leaves much to be desired. Expanding the basket of choices and mainstreaming indicators pertaining to informed decision making and rights-based care is imperative.

For Pete’s Sake is a non-profit organization that provides adult cancer survivors and their families with complimentary holistic support. Families receive a 4–7-day respite experience. Post-respite, family members receive ongoing support (monthly newsletters, private Facebook groups, monthly gatherings, annual events). Anecdotally, families report feeling happier, closer, and recharged for battling cancer, so the purpose of this study was to assess these outcomes. This was a single group, pre-test/post-test study. Oncology professionals nominated 24–55-year-olds with physician-diagnosed cancer (any stage/site) clinically able to partake in a respite experience. Families selected destinations (e.g., Florida, Caribbean, Jersey Shore) and received materials to encourage communication and an emotionally/spiritually meaningful experience. Of the 464 families completing respites in 2014–2019, 190 families (41%) provided pre- and post-respite data, and 104 families (55%) completed the 6-month follow-up. Pre-, immediately post-, and 6-months post-respite, cancer survivors, caregivers, and children completed surveys assessing family hardiness, spousal or parent–child communication, cancer coping efficacy, and joviality. Cancer survivors experienced post-respite increases in family hardiness, caregiver and child communication, joviality, and coping efficacy. Caregivers experienced post-respite increases in survivor communication, joviality, and coping efficacy but not family hardiness. Children experienced post-respite increases in joviality, but not family hardiness or communication. At the 6-month follow-up, survivor family hardiness returned to pre-respite levels and child communication decreased, but all other outcomes were higher than pre-respite levels. All caregiver outcomes were higher than pre-respite levels; child outcomes returned to pre-respite levels. These results suggest that investing resources in families may help improve relationships and facilitate efforts to stay engaged in the cancer battle.

Published: February 2025

This report summarizes the numerical modeling and probabilistic analysis performed by the US Army Engineer Research and Development Center Coastal and Hydraulics Laboratory (CHL) as part of the Upper Barataria Basin (UBB) Coastal Storm Risk Management (CSRM) Study. The intent of this work, performed for the US Army Corps of Engineers (USACE) and St. Paul District, was to evaluate project alternatives to assess flooding risks induced by coastal storms in coastal Louisiana. This study applied the USACE’s Coastal Storm Modeling System for storm surge and wave modeling and Coastal Hazards System–Probabilistic Framework (CHS-PF) to quantify water level and wave hazards, leveraging existing synthetic tropical cyclones (TCs) from the Coastal Hazards System–Louisiana (CHS-LA) study for levee recertification. Using a reduced storm suite (RSS) of synthetic TCs from CHS-LA, hydrodynamic model simulations were performed on an updated grid, including five proposed levee systems, to produce storm responses at more than 184,000 mesh node locations and over 21000 special save point locations within the UBB project area. Through the application of the CHS-PF, the joint probability analysis of TC atmospheric-forcing parameters and their associated storm responses were assessed for the estimation of still water level (SWL), significant wave height (Hm0), and wave peak period (Tp) annual exceedance frequencies ranging from 10 to 1 × 10−4 yr−1 to evaluate the impact of the UBB with- and without-project conditions.

Authors: Zaidi Huma , Dube Rajani , Kuruba Manjunatha Goud Bellary , Khan Shehla Shafi , Kar Subhranshu Sekhar , Jadaan Omar Al
Published: February 2025

Background
Student-teacher relationships (STR) in health professions education impact students' academic performance, professional development, and mental well-being. Understanding the determinants of these relationships is essential for fostering an effective and supportive learning environment, particularly in the emotionally demanding context of health education.
Methods
This study used a mixed-methods approach, combining quantitative surveys to measure perceptions of student-teacher relationships with qualitative interviews to explore underlying factors influencing these interactions. Data were collected from students and faculty across diverse health professions programs and analyzed using statistical and thematic analysis techniques.
Results
A total of 333 students participated in the quantitative survey with the majority being medical students (38.4%). Ten faculty and students participated in the qualitative study. The majority were female students (68.2%), and from the 2nd year of study. Students identified personal qualities of being impressive and inspiring teachers, who are warm, compassionate, and demonstrate trustworthy, well-intentioned, and reliable behavior as the factors instilling confidence in them. Reliability was the most important factor identified for strong STR with 75.8% of medical and 68.8% of pharmacy students sharing the opinion that reliability of the teachers is very important aspect. STR can affect teachers' performance, students' attendance in class, as well as their academic achievements. Students appreciated qualities in their own teachers. The views about teacher qualities, STR, teacher’s actions, and effect on teachers and attendance had diverse responses from students. They agreed on most points, while displaying significant differences among different year students, colleges, and different grade point average categories on others.
Conclusion
This bidirectional relationship affects students in terms of attendance, discipline, and academic achievement, and teachers in self-confidence, and performance as an educator. Health professional students consider teacher characteristics like a friendly approach, reliability, and trustworthiness important for STR, and motivation to learn. Both teachers and students view that technology should be appropriately used to benefit STR.

Measures from affinity-proteomics platforms often correlate poorly, challenging interpretation of protein associations with genetic variants (pQTL) and phenotypes. Here, we examined 2,157 proteins measured on both SomaScan 7k and Olink Explore 3072 across 1,930 participants with genetic similarity to European, African, East Asian, and Admixed American ancestry references. Inter-platform correlation coefficients for these 2,157 proteins followed a bimodal distribution (median r=0.30). Protein measures were associated with variants (pQTLs), and one-third of the pQTL signals were driven by protein-altering variants (PAVs). We highlight 80 proteins that correlate differently across ancestry groups likely due to differing PAV frequencies by ancestry. Furthermore, adjustment for PAVs with opposite directions of effect by platform improved inter-platform protein measure correlation and resulted in more concordant genetic and phenotypic associations. Hence, PAVs need to be accounted for across ancestries to facilitate platform-concordant and accurate protein measurement.

Magnaporthe oryzae causes rice blast disease and is an invasive threat to global rice crops production. Recent investigations revealed that sphingolipids play an important role in various cellular processes and give us molecular insights into roles of sphingolipid genes and their derivatives in plant pathogenic fungal disease reduction. However, the function of sphingolipids and their respective proteins in M. oryzae have not yet been understood in detail. To thoroughly understand the pathological role and characterization of sphingolipid proteins involved in virulence causing rice blast disease is demanded. In this research work, we carried out systematic analysis of another gene from sphingolipid pathway, which was found to be responsible for conidia development and pathogenicity. Knockout of MoSur2, a key sphinganine C4-Hydroxylase, resulted in significant disruption in the hyphal and conidia growth, and displayed a remarkable decrease in plasma membrane (PM) tension and virulence on the host plant. MoSur2 is also necessary for regulating cell wall intensity (CWI), and osmotic and oxidative stress Osm1-MAPK pathway. TORC2 analysis revealed that phosphorylation of Ypk1 regulates the PM stress and increases in feedback mechanism in the ∆Mosur2 mutant. By comprehensive lipidomics analysis, we found out significant alterations in major plasma membrane components resulting in increased level of phosphatidylethanolamine (PE) and phosphatidylcholine (PC) alongside decreased level of ceramide (Cer) in the mutant. Moreover, MoSur2 is localized in the ER and its interaction with upstream proteins Spt2 and Tsc10 shows that the pathway is highly systematic. The inhibition effect of myriocin gives us insight that MoSur2 mutant could be a potential drug target. These findings improve our understanding of the characterization and functionalization of MoSur2 of the sphingolipid pathway and could be very useful for controlling rice blast disease through the development of specific drugs.

Objective
Several replacement protocols for frozen-thawed ET (FET) exist, with no advantage of one protocol over the others. In the present study we aim to evaluate the hormonal changes round the LH surge, for better determination of the LH surge and improving the NC FET outcome.
Patients and methods:
We reviewed the computerized files of all consecutive women admitted to our IVF Institute, between January 1, 2023 and June 30, 2024, who underwent NC FET cycles in our IVF Institute. The elimination of bias in this selection, for the purposes of this study, was achieved by including only patients who had two consecutive hormonal blood tests and transvaginal ultrasound evaluations prior to ovulation, on two days (D-2) before and one day before ovulation (D-1). Data on patient demographics and infertility-treatment-related variables were collected from the files. We studied and compared several variable between patients who conceived and those who did not, including the % changes in LH (D-1 minus D-2/ D-2), in estradiol (D-2 minus D-1/ D-2) and % change in progesterone (D-1 minus D-2/ D-2) levels.
Results
Six hundreds and sixty-eight NC FET cycles were performed during the study periods. Pregnancy was achieved in 348 patients (pregnancy rate, 52% per cycle). Patients who conceived were significantly younger, with no in-between group differences in LH, E2 and progesterone levels on D-2 nor D-1. Moreover, while no differences were observed in the % changes in E2, nor LH levels, the % change in progesterone (D-1 minus D2/ D-2) levels was significantly higher in those who conceived (1.9 + 1.5 vs 1.6 + 1.4, p < 0.013), as compared to those who did not.
Conclusions
Patients undergoing NC FET should be monitored by LH, estradiol and progesteron levels. The LH surge should be determined by an increase in LH, concomitant to a drop in estradiol and a 3-fold increase in progesterone levels between D-2 to D-1. Further large prospective studies are needed to elucidate the aforementioned recommendation prior to its routine implementation.
Genetic variation of hypoxia tolerance in farmed fish: a systematic review for selective breeding purposes

The acceleration of climate change and increasing water pollution have contributed to a global increase in hypoxic events in the oceans. As a result, this environmental stressor has had significant economic repercussions for the marine aquaculture sector. Consequently, selective breeding for hypoxia-tolerant fish is being explored as a promising strategy to mitigate climate change effects. In this context, the present systematic review synthesizes and critically evaluates current knowledge regarding the genetic variation associated with hypoxia tolerance in farmed fish species. A literature search was conducted in Scopus and Web of Science, following the PRISMA 2020 guidelines. In total, 963 articles were identified, of which 40 met the inclusion criteria, encompassing 29 species and three hybrid lines. Among the farmed fish, the blunt snout bream (Megalobrama amblycephala), rainbow trout (Oncorhynchus mykiss), common carp (Cyprinus carpio) and Nile tilapia (Oreochromis niloticus) were the most extensively studied. The most commonly used traits to measure hypoxia tolerance included: 1) time of loss of equilibrium (tLOE), 2) survival time or status (alive/dead) and 3) critical oxygen partial pressure (Pcrit), measured via respirometry. Notably, 22 studies reported substantial variability in hypoxia tolerance across families, strains, gynogenetic lines, growth-transgenic lines, hybrids, and species. Moreover, 15 studies identified SNP markers significantly associated with hypoxia tolerance; however, heritability estimates, reported in only two studies, ranged from 0.28 to 0.65. Furthermore, candidate genes were frequently identified as downstream effectors of the HIF pathway or as components of signaling pathways such as VEGF and mTOR, which are critical for angiogenesis and energy conservation, respectively. Additionally, genes involved in erythropoiesis, ion regulation, glucose metabolism, DNA repair, and iron metabolism, key processes in the hypoxia response, were identified. Given that aquatic environments are becoming increasingly hypoxic, these findings underscore the potential of the inherent genetic diversity present in farmed fish populations. In this context, genomic selection and gene editing emerge as promising tools for developing hypoxia-tolerant fish lines. Nevertheless, further research is warranted to implement such lines under field conditions, particularly because the correlations between hypoxia tolerance and other economically important traits, such as growth and pathogen resistance, remain largely unknown.

Millions of people worldwide suffer from asthma, a chronic respiratory disease marked by symptoms such as shortness of breath, wheezing, and coughing. This retrospective study assessed socio-demographic characteristics, treatment outcomes, and factors influencing asthma management among 389 patients at the Federal Medical Centre, Owerri, Nigeria, from 2017 to 2022. Statistical analysis was conducted using SPSS version 25.0, with significant findings highlighted to support targeted asthma care strategies. Demographic analysis showed that 43% of patients were aged 30–45 years, with 54% being female. Urban residence (62%) and environmental exposures to pollutants (33.7% in 2017 and 32.9% in 2022) were consistent contributors to asthma prevalence, alongside a strong family history (peaking at 50% in 2020). Logistic regression revealed that adult-onset asthma (p = 0.005, odds ratio [OR] = 1.67) and difficult-to-control and severe asthma (p = 0.001, OR = 2.30) were significantly associated with poor outcomes, emphasizing the need for intensified management for these patient groups. While childhood asthma and eosinophilic asthma showed positive but non-significant associations (OR = 1.26 and OR = 1.51, respectively), occupational asthma indicated a protective trend (OR = 0.70, p = 0.11). Seasonal asthma showed no significant impact (OR = 1.19, p = 0.37). Repeated measures ANOVA identified significant year-to-year variations in symptom improvement (F = 4.23, p = 0.001, partial eta squared = 0.047) and attack frequency (F = 3.51, p = 0.004, partial eta squared = 0.039). Post-hoc analysis showed notable improvements in symptom relief and reduced attack frequency between 2017 and 2021 (p = 0.01 and p = 0.02, respectively) and 2018 and 2022 (p = 0.03 and p = 0.04, respectively). However, fluctuations in treatment outcomes, such as a slight decrease in significant symptom improvement from 44.9% in 2017 to 39.5% in 2022, underscore persistent challenges in long-term asthma management. This study highlights the necessity of addressing genetic predispositions, environmental exposures, and severe asthma types to improve management outcomes. Public health interventions should focus on personalized care, urban exposure reduction, and enhanced patient education.

Lithium iron phosphate (LiFePO₄ or LFP) is a critical cathode material in electric vehicle batteries, although its recycling is constrained by limited economic feasibility. This study proposes an innovative H₂O₂-CO₂ leaching strategy for the selective extraction of lithium from spent LFP batteries. This approach operates at ambient temperature and pressure, delivering a straightforward process with high leaching efficiency. Optimal conditions yield a lithium leaching efficiency greater than 95%, with kinetic analysis indicating that the process is primarily controlled by solid layer diffusion. For impurity control, iron and phosphorus are removed by high-temperature treatment, and copper is effectively removed using an electrochemical method, resulting in a high purity of more than99.6% of the Li₂CO₃ product. Life cycle assessment highlights the substantial reductions in energy consumption and greenhouse gas emissions, alongside notable economic advantages of this process. This approach is a promising, sustainable, and economically advantageous solution for recycling spent LFP batteriesand has substantial application potential.

Published: February 2025

Diversos estudos apresentaram diferentes correlatos do bem-estar psicológico. O presente estudo apresenta os impactos da espiritualidade, do sentido de vida e da qualidade de vida em relação ao bem-estar psicológico (BEP) total da população investigada. Participaram da pesquisa 841 adultos (amostra de conveniência), sendo a maioria do sexo feminino (70,9%), com idade variando entre 18 e 86 anos (M= 35,21; DP= 13,96). A coleta de dados foi realizada de modo virtual, por meio de um questionário contendo perguntas sociodemográficas e as seguintes escalas: Questionário de Sentido de Vida; Escala de Bem-Estar Psicológico; Instrumento de Qualidade de Vida (WHOQOL-Abreviado); e Instrumento de Qualidade de Vida, Módulo Espiritualidade, Religião e Crenças Pessoais-WHOQOL-SRPB. Foram realizadas análises de regressão linear múltipla, cujos resultados apontam que cada dimensão do BEP é impactada por diferentes variáveis. As mais comuns através de todas as dimensões são: WHOQOL Domínio Psicológico, explicando diretamente as seis dimensões; e o WHOQOL Domínio Físico, explicando diretamente quatro das seis dimensões. O escore total de Espiritualidade foi um preditor significativo de quatro das seis dimensões do BEP, enquanto pelo menos uma das duas dimensões de sentido de vida contribuiu significativamente para cinco dimensões do BEP. Os dados do estudo demonstraram contribuições importantes dos fenômenos investigados para o funcionamento saudável dos indivíduos, confirmando resultados de outras pesquisas científicas e fornecendo subsídios para novos estudos.
