An analysis of active consumer behavior in a fitness boutique: satisfaction levels, perceived quality dimensions, and dropout reasons

The European fitness market is experiencing continuous growth, prompting enhancements in service quality at boutique gyms. These establishments are recognized for their personalized attention, professional staff, and innovative technology use. The perceived quality in these gyms significantly influences client satisfaction and loyalty, which are critical for retention. The aim of the contribution is to understand satisfaction levels, perceived quality dimensions, and dropout reasons inside this business model. The study sample comprises 67 adults, aged 18 to 70 years, predominantly aged 41-50. The EPOD2 Questionnaire and Dropout Reasons Scale were utilized for data collection. An analysis of a boutique fitness center in Zaragoza (Spain), indicates high demand, particularly among women. Most users positively rate the service, especially commending the staff, though communication is rated lower. Higher satisfaction is associated with increased loyalty, and reasons for dropout include distance and congestion, consistent with previous studies. The study has some limitations, including: sample size, gender imbalance, and a lack of longitudinal data. Further approaches should encompass larger samples, longitudinal designs, and broader comparisons to enhance the understanding of satisfaction and loyalty in boutique fitness centers.

Different lines of camelina (Camelina sativa (L.) Crantz) in broiler quails’ diets: effects on meat physicochemical traits and sensory profile

The present study investigated the effect of Camelina sativa cake dietary inclusion on quail meat fatty acids (FA), amino acids (AA), and sensory characteristics. To this, 480 broiler quails were allocated to four dietary treatments (12 replicated cages/treatment): a control diet (Control) and three diets with 15% camelina cake, containing a commercial cultivar (Calena) and two improved lines (Pearl: low linoleic acid; Alan: low glucosinolates). After slaughter, breast meat FA and AA profiles and contents were analysed, alongside a sensory evaluation by trained panellists. The dietary inclusion modified breast meat FA profile and contents (p < .001), notably increasing α-linolenic acid (C18:3 n-3), which improved overall n-3 PUFA and reduced the n-6/n-3 ratio to recommended levels. Health indices improved in a line-dependent manner: atherogenicity lowered in Alan compared to Control and Calena (p < .01), while thrombogenicity reduced in all camelina treatments than the Control (p < .001). Camelina-fed groups showed an AA profile in line with the Control one, and Pearl displayed a higher essential AA content compared to Alan (p < .05). Sensory results indicated no substantial changes in meat attributes across treatments, except for tenderness and animal fat flavour: the first lowered in Alan meat compared to the Control (p < .05), while the latter was higher in the Control than in Alan and Calena groups (p < .01). In conclusion, the 15% dietary inclusion of different camelina cakes in quail diets positively influenced meat FA, enhancing product healthiness without negatively impacting its nutritional quality and sensory attributes. Findings indicated that camelina cake is an effective feedstuff to improve quail meat quality. HIGHLIGHTS Once fed to quails, all tested camelina cakes increased meat n-3 PUFA and reduced the n-6/n-3 by about 5 and 7 times, respectively. Meat atherogenicity and thrombogenicity indices of camelina-fed quails improved, indicating enhanced product healthiness. Camelina inclusion did not alter quail meat sensory attributes compared to the control group.

SELECTION OF TOOLS AND MACHINING PARAMETERS FOR PIPE WALLS

This review paper examines the techniques and factors involved in pipe wall processing, with a focus on the essential technologies utilized in this field. The study revealed crucial elements, such as ASTM A350-LF2 Class 1 carbon steel, renowned for its exceptional mechanical qualities and ability to withstand low temperatures. An exhaustive analysis has been conducted on the chemical makeup of this steel to comprehend its capacity to adjust and endure in various operational environments. The study focused on examining several particle separation processes, including as turning, milling, drilling, and grinding, in order to determine the exact equipment and criteria needed for each technique. The cooling and lubricating process received particular emphasis, with thorough investigation of several agents, including CASTROL HYSOL T15, and their impact on surface quality and tool longevity. The utilization of these compounds has been discovered to substantially decrease tool temperature and enhance machining quality. Upon closer examination of the processing techniques specified in section A-A of the tube wall, it was determined that advanced procedures such as floating plug drawing and micro-sized spiral tube hydroforming were discovered. These techniques allow the attainment of superior surface quality and precise dimensions, which are crucial for guaranteeing the structural integrity of the pipe. Cutting tools, processing equipment, and coolants and lubricants are essential components in the manufacturing of pipe walls. Nanoparticulate cooling and lubrication systems, which are advanced technologies, have demonstrated their effectiveness in minimizing friction and heat during machining. As a result, these systems enhance productivity and prolong the lifespan of tools. According to the article, the essential components for attaining high-quality manufacture of pipe walls are cutting tools, processing equipment, and coolants and lubricants. Additional study is advised to enhance processing parameters, create eco-friendly coolants and lubricants, and utilize artificial intelligence for predictive modeling and optimization of processing. This establishes the groundwork for future research and innovation in the pipe wall production business, with the objective of attaining enhanced efficiency and sustainability in production processes.

The active kappa-carrageenan coating and oxygen absorber packaging for the preservation of chilled rainbow trout fillets

The objective of the current research was to evaluate the effects of incorporating kappa-carrageenan (KCA) coating with dill essential oil (DEO), in conjunction with oxygen absorber (OA) packaging, on the quality attributes of rainbow trout fillets throughout a 20-day period of refrigerated storage. The administered treatments included OA, KCA + OA, KCA + DEO, KCA + DEO + OA, and control. Treating the trout fillets with DEO-loaded coating and/or using OA packaging was found to be more effective in restricting the growth of total mesophilic and psychrotrophic bacteria, Enterobacteriaceae, and lactic acid bacteria. The aforementioned treatments were more efficient in slowing down the rate of increase in pH, total volatile nitrogen, conjugated dienes, thiobarbituric acid reactive substances, protein carbonyls, electric conductivity, and organoleptic deterioration in the trout fillets. Notably, the most effective treatment in this context was KCA + DEO + OA. The shelf-life of trout fillets was established through the assessment of multiple parameters. It was determined to be 4 days in both the control and KCA groups, 8 days in the OA and KCA + OA groups, 16 days in the KCA + DEO group, and a minimum of 20 days in the KCA + DEO + OA group. Consequently, our recommendation is to apply an active coating based on KCA, incorporating DEO in conjunction with OA packaging, for the preservation of fish fillets stored in refrigeration.

Based on the Principle Component Analysis of the Level of Cultural and Tourism Integration in a Place and Obstacles Analysis

China’s culture is one of the oldest and most complex in the world, with a history that spans thousands of years. Rooted in Confucianism, Taoism, and Buddhism, Chinese culture emphasizes harmony, respect for tradition, and the importance of family. These philosophies have profoundly influenced the social values, customs, and daily life of the Chinese people. This study aimed to identify 10 different dimensions and the perception of quality amongst tourists based on the rural tourism experience. Perceived value and tourism satisfaction are seen as two constructs that bridge the gulf between these quality perceptions and the tourists’ future behavior — that is, the intent of tourists to revisit, spread positive word-of-mouth, and their propensity to splurge on unique rural products. Furthermore, we also examined the respondents’ areas where they lived in urban or rural areas which would affect their perceptions and behaviors. The analysis was identified using data from 650 respondents’ four key quality dimensions: tourism environment and transportation, companionship and learning, culture and local items, and rural environment as perceived by the tourists. Indeed, the findings lend considerable empirical support to the relationship of perceived quality with perceived value, satisfaction, and the dimensions of the behavioral intentions of tourists. Interestingly, the study showed residents — the urban and rural residents of tourists — as a very important moderator of these relationships. These are important insights that would be invaluable in explaining the driving factors of tourists’ intentions and the imperative for the sustainable growth of rural tourism in China.

Abstract 4136745: How do sleep quality and heart failure symptoms impact functional status among patients with heart failure?

Background: Patients with heart failure (HF) frequently experience poor sleep quality and multiple HF symptoms, both of which are linked to diminished functional status. Poor sleep quality can manifest as prolonged latency, short duration, low efficiency, or difficulty staying asleep. HF symptoms encompass different dimensions: presence, frequency, severity, and distress of HF symptoms. Different dimensions of sleep quality and HF symptoms may uniquely influence functional status, necessitating tailored interventions, yet how individual dimensions of sleep quality and HF symptoms impact functional status remains unexplored. Research Question: how do individual dimensions of sleep quality and HF symptoms impact functional status in patients with HF? Methods: We studied 197 adults with HF (male: 66%, age: 62±11 yrs). The Pittsburgh Sleep Quality Index was used to assess seven dimensions of sleep quality: subjective sleep quality, latency, duration, efficiency, sleep disturbances, use of sleeping medications, and daytime dysfunction over the last month. Four dimensions (i.e., presence, frequency, severity, distress) of 7 HF symptoms (e.g., shortness of breath, fatigue, swelling) were assessed using the Symptom Status Questionnaire-HF. Functional status was measured using the Duke Activity Status Index. Correlations and two multiple linear regression models (1 st model: 7 dimensions of sleep quality on functional status, and 2 nd model: 4 dimensions of HF symptoms on functional status) were conducted for data analysis. Results: Worse subjective sleep quality, longer latency, more sleep disturbances, use of sleeping medications, and higher levels of daytime dysfunction were correlated with poor functional status. All four dimensions of HF symptoms were negatively correlated with functional status. In the 1 st multiple linear regression model, more sleep disturbances (B=-3.91, p =.006) and higher daytime dysfunction (B=-5.70, p &lt;.001) were predictive of poor functional status (model R 2 =0.23, p &lt;.001). In the 2 nd multiple linear regression model, only higher frequency of HF symptoms (B=-.70, p =.022) predicted poor functional status (model R 2 =0.34, p &lt;.001). Conclusion: Increased sleep disturbances, daytime dysfunction, and frequency of HF symptoms were associated with poorer functional status in patients with HF. These findings underscore the importance of developing tailored interventions to address individual sleep problems and HF symptoms to improve functional status.

Evaluation of the Effects of Electrical and Carbon Dioxide Stunning Methods on Quality Attributes of Pork Meat

In our experiment, the effect of electrical and CO2 stunning on pork meat quality attributes was studied. A total of thirty PIC337 female pigs were allocated to two equal groups which were stunned electrically (50 Hz, 210 V, 2.6 A, 15 s) or by CO2 (85 V% CO2, 15 V% O2, 90 s) and slaughtered at a commercial slaughterhouse. For 24 h post mortem, the carcass m. gluteus medius (GM) was used to evaluate meat quality attributes such as pH, color, hardness, water holding capacity (WHC), and total pigment content, and meat classification was also carried out. The CO2 stunning resulted in muscle with significantly lower pH (p &lt; 0.01) and poorer water holding capacity (p &lt; 0.05) compared to electrical stunning. The GM of pigs stunned electrically showed significantly increased lightness (L*) and redness (a*) (p &lt; 0.05) compared to CO2-stunned. The time course of development of rigor mortis was similar for both stunning methods. Pale, soft, exudative (PSE) or dark, firm, dry (DFD) meat defects were not observed. Based on total pigment content, stunning methods did not significantly affect the amount of removable blood.

Development of the Indonesian sexual quality of life scale for women (ISQOL-W).

Sexual quality of life is greatly influenced by sexual function, yet thorough measures remain limited and vary across regions. In Indonesia, diverse cultural and religious contexts notably shape sexual quality of life. Thus, it is important to have a tool that considers both internal and external aspects. The aim of this study was to develop a valid and reliable scale that specifically measures Indonesian sexual quality of life for women (ISQOL-W), considering cultural and social factors. A total of 228 participants were recruited from April 30, 2023, to September 30, 2023. The ISQOL-W was developed through two phases: item generation and psychometric evaluation. In the first phase, 68 items were drafted based on definitions and dimensions of sexual quality of life. In the second phase, exploratory factor analysis resulted in 34 items with a loading factor greater than 0.4 (ranging from 0.41 to 0.84) which were categorized into four domains/factors: sexual-related emotion, sexual fantasy, sexual arousal, and sexual relationship. The Cronbach's α coefficient for the overall questionnaire was 0.915, with subscale reliability ranging from 0.826 to 0.903. Further analysis revealed significant differences in ISQOL-W scores across relationship status, educational level, history of last sexual activity, and type of sexual activity. In conclusion, the ISQOL-W demonstrated robust psychometric properties, supporting its use in future studies. This study represents the first effort to develop and validate a sexual quality of life scale specifically for Indonesian women.

The influence of citrate buffer molarity on mRNA-LNPs: Exploring factors beyond general critical quality attributes

Lipid nanoparticles (LNPs) are crucial in delivering mRNA vaccines and therapeutics. The properties of LNPs can be influenced by the choice of lipids and the manufacturing conditions, such as mixing parameters, lipid concentration, and the type and concentration of the aqueous buffer used. In this study, we investigated the impact of the citrate buffer molarity, the buffer commonly used to dissolve mRNA in the preparation of mRNA-LNPs. We prepared SM-102 LNPs containing firefly luciferase mRNA using citrate buffers at molarities of 50 mM, 100 mM, or 300 mM. Our findings revealed that varying the molarity of the citrate buffer did not significantly affect the particle size when considering the average diameter (z-average or Mode). All formulations exhibited low polydispersity index (PDI) and high encapsulation efficiency. Detailed analysis of particle size sub-populations (D10, D50, and D90) and morphology indicated that citrate buffer concentration might influence lipid packing during LNP production, though these differences were subtle. However, using higher citrate molarity (300 mM) to produce LNPs notably reduced cellular internalisation and in vitro transfection efficiency. This trend was also observed in vivo, where similar expression levels were noted in mice receiving the 50 mM and 100 mM LNP formulations, but lower expression was seen for the 300 mM formulation. Our study highlights the importance of buffer molarity in the aqueous phase during mRNA-based LNP preparation and that generally reported critical quality attributes (CQAs) for LNPs may not detect subtle formulation differences.

Early Quality Prediction of Complex Double-Walled Hollow Turbine Blades Based on Improved Whale Optimization Algorithm

Abstract The precision in forming complex double-walled hollow turbine blades significantly influences their cooling efficiency, making the selection of appropriate casting process parameters critical for achieving fine-casting blade formation. However, the high cost associated with real blade casting necessitates strategies to enhance product formation rates and mitigate cost losses stemming from the overshoot phenomenon. We propose a machine learning (ML) data-driven framework leveraging an enhanced whale optimization algorithm (WOA) to estimate product formation under diverse process conditions to address this challenge. Complex double-walled hollow turbine blades serve as a representative case within our proposed framework. We constructed a database using simulation data, employed feature engineering to identify crucial features and streamline inputs, and utilized a whale optimization algorithm-back-propagation neural network (WOA-BP) as the foundational ML model. To enhance WOA-BP’s performance, we introduce an optimization algorithm, the improved chaos whale optimization-back-propagation (ICWOA-BP), incorporating cubic chaotic mapping adaptation. Experimental evaluation of ICWOA-BP demonstrated an average mean absolute error of 0.001995 mm, reflecting a 36.21% reduction in prediction error compared to conventional models, as well as two well-known optimization algorithms (particle swarm optimization (PSO), quantum-based avian navigation optimizer algorithm (QANA)). Consequently, ICWOA-BP emerges as an effective tool for early prediction of dimensional quality in complex double-walled hollow turbine blades.

The Gap Between Trustworthy AI Research and Trustworthy Software Research: A Tertiary Study

With the increasing application and complexity of Artificial Intelligence (AI) systems, the trustworthiness of AI has garnered widespread attention across various fields. An AI system is a specific type of software system with unique trustworthiness requirements due to its distinctive characteristics in data and algorithms. Our objective is to investigate the state-of-the-art in trustworthy AI and trustworthy software separately and to analyze the connections and gaps between them. To this end, we conducted a tertiary study, which is a systematic literature review of existing secondary studies. These secondary studies are divided into two groups: one focuses on trustworthy AI and the other on trustworthy software. We developed frameworks for both trustworthy AI and trustworthy software, summarized the definitions of quality attributes in a structured format, and analyzed the similarities of these attributes between the two areas. Additionally, we created a swimlane diagram illustrating trustworthy practices throughout the development life-cycle and in relation to specific quality attributes. Researchers in these two areas originate from distinct research communities, leading to a significant gap between the trustworthiness of AI and software. However, we believe that existing research on trustworthy software can effectively address some gaps in trustworthy AI research, and we have identified evidence of connections between the two areas.

Effect of the Freeze-Drying Preservation Process on Some Quality Attributes of Pork Meat (Longissimus thoracis).

Meat preservation processes have been widely studied over time, especially those related to low temperatures (freezing and freeze-drying); however, there is very little research that directly relates the effect of these processes on the structure of meat-and the main meat proteins-and how these changes affect some attributes of the final quality. Pork loin meat (Longissimus thoracis) was used, which was frozen-thawed and freeze-dried-rehydrated to subsequently evaluate changes in its chemical composition and physicochemical parameters such as water activity (a w), pH, and water-holding capacity. Physical aspects such as color profile, surface myoglobin fraction, shear force, and histological sections were also evaluated, along with thermal analysis by modulated differential scanning calorimetry. The data obtained were analyzed through different statistical techniques. It was found that the freeze-drying process significantly modifies the interactions of water with the rest of the meat components (p < 0.05), promoting differences concerning samples that were only frozen, allowing us to establish the importance of water and its associations with each other and with proteins on their effect on meat preservation processes at low temperatures.

Illuminating Hypomania in Early Adolescence: Associations Between Dark-Side and Bright-Side Hypomania, Insomnia, and Health-Related Quality of Life.

Background: Adolescence is a period of significant psychological, physical, and social changes. During this time, adolescents face increasing responsibilities, such as making educational and career decisions, managing peer relationships, and becoming more independent from their families. These changes are often accompanied by mood fluctuations and altered sleep patterns. This study aimed to explore the relationships between bright- and dark-side hypomania, insomnia, and various dimensions of health-related quality of life (HRQOL), such as self-esteem, family and peer relationships, social acceptance, and autonomy. Methods: A total of 1475 participants in mid-adolescence (mean age: 13.4 years; range: 11-16 years; 48.8% males) completed a series of self-reported questionnaires covering sociodemographic information, hypomania, including dark and bright-side hypomania, insomnia, and HRQOL. Results: Compared to participants with no or dark-side hypomania, participants with bright-side hypomania reported better HRQOL. Bright-side hypomania was significantly associated with favorable relationships with parents and home, peer relationships, and the school environment and with less insomnia. In contrast, dark-side hypomania showed significant associations with lower scores for self-esteem, moods and emotional states, peer relationships, social acceptance, the school environment, and more insomnia. Conclusions: Among a larger sample of adolescents, bright- and dark-side hypomania were associated with a broad, though specific variety of aspects of HRQOL and insomnia. Given that standardized programs are available to improve insomnia and resilience as a proxy of psychological well-being, such interventions may have the potential to improve adolescents' psychological well-being and sleep quality concomitantly.

Burnout and sleep quality in sports managers

Sports managers have great responsibilities aimed at coordinating and directing the organization through the employed staff who will be given precise tasks, regardless of their hierarchical position. Perfectionism or unfulfilled expectations can influence employees’ subjective state, making them more or less vulnerable and prone to burnout. In the present study sleep quality and burnout dimensions (exhaustion and work disengagement) were addressed, in successful sports managers (n = 20), and, also, in the case of future managers (n = 23). The Oldenburg Burnout Inventory and The ATHENS Insomnia Scale were used. For data analysis and processing independent sample t-test and Mann-Whitney (U) test were performed. The results emphasized that female successful managers reported significantly poorer sleep quality and higher daytime sleepiness compared to male successful sports managers. Gender-related differences in terms of burnout dimensions were, also, discussed.

Examining the interplay between mental health indicators and quality of life measures among first-year law students: a cross-sectional study.

This research explores the intricate relationships between mental health indicators (depression, stress, and anxiety) and various dimensions of quality of life among first-year law students. The study aims to understand how affective valence, mood states, physical activity, body image perception, and social relations influence mental health outcomes. Data were collected from 75 first-year law students (46 females, 29 males), a group predominantly composed of young adults with limited financial means, living in various housing situations, primarily within urban environments, and generally reporting low levels of physical activity. Standardized questionnaires were used to assess mental health and quality of life, including the Depression, Anxiety, and Stress Scale-21 Items (DASS-21), Feeling Scale (FS), Exercise-Induced Feeling Inventory (EIFI), Modified Baecke Physical Activity Questionnaire (MBPAQ), World Health Organization Quality of Life-BREF (WHOQOL-BREF), and Contour Drawing Rating Scale (CDRS). Descriptive statistics, Pearson correlation, and regression analysis were employed to analyze the data. The analysis revealed significant correlations between depression (mean = 5.97, SD = 4.21), stress (mean = 7.81, SD = 4.80), and anxiety (mean = 6.17, SD = 4.58) with affective valence (p < 0.05), mood states (p < 0.05), physical activity (p < 0.05), body image perception (p < 0.05), and social relations quality (p < 0.05). Additionally, mood states (mean = 20.73, SD = 10.60), physical activity (mean = 8.43, SD = 1.35), body image perception (mean = 4.21, SD = 1.91), and social relations quality (mean = 12.46, SD = 2.33) were identified as significant predictors of mental health outcomes (p < 0.05). These findings underscore the complex interplay between mental health indicators and various dimensions of quality of life, emphasizing the necessity for a comprehensive approach to mental health care. By identifying these predictors, we have gained a clearer understanding of the factors that impact mental health in this specific population. The insights gained highlight the value of interventions aimed at improving mood, increasing physical activity, enhancing body image, and strengthening social connections. These targeted strategies could effectively address mental health issues and promote well-being among law students. Future research should further investigate these relationships and develop tailored interventions to better support students' mental health. This study contributes to understanding the complex interplay between mental health and quality of life, offering a foundation for both practical interventions and future research.

Clinical Factors Affecting the Quality of Life of Women With Endometriosis.

The study aimed to analyse selected clinical data affecting the quality of life of women with endometriosis. A cross-sectional study. The study was conducted in 2020-2022 among 425 women with endometriosis receiving health care. A diagnostic survey method with a questionnaire technique was used. The research tools are the Endometriosis Health Profile and a standardised interview questionnaire. Infertility, medical treatment and sexual intercourse were the dimensions of quality of life most poorly rated by respondents with endometriosis. Lower quality of life was linked to the presence of painful periods, the presence of pain during intercourse and having surgery for endometriosis. The main clinical variables influencing the quality of life of women with endometriosis include problems with getting pregnant, the necessity for long-term therapy and sexual problems caused by the condition. The occurrence of painful menstruation, dyspareunia and having undergone surgery for endometriosis is associated with lower ratings of women's general quality of life. The study will help to develop a more holistic approach to caring for endometriosis patients. This will result in a better diagnosis, individualised therapy and psychological support, all of which will enhance the overall quality of life. The study's results may impact the development of health policies, endometriosis support services for women and public awareness initiatives. The study highlighted key determinants affecting health-related quality of life for women with endometriosis. The analysis of clinical data revealed that infertility, treatment and dyspareunia are the dimensions of quality of life most poorly rated by women with endometriosis. These findings are significant for those providing care to women with endometriosis, as well as for policymakers responsible for the organisation of health care systems. The STROBE guidelines. No patient or public contribution.

A Six Sigma and DEA Framework for Quality Assessment in Banking Services

This study proposes a methodology that combines Six Sigma and Data Envelopment Analysis (DEA) to measure the quality of banking services. The proposed framework emphasizes seven essential quality dimensions: prompt response, efficient channels, fraudulence, processes, dependable service, credibility, customer satisfaction, and risk management. Integrating both techniques enables a holistic approach to quality evaluation and provides valuable information for the banking industry’s continual improvement. To validate the properties of the methodology, we developed a case study involving 25 Colombian banks. Using Six Sigma metrics, DEA models, and slacks analysis, the results provide a comprehensive study of the quality performance, identifying each bank’s relative strengths and weaknesses in several quality dimensions. The data indicate that some banks perform better on quality characteristics such as customer happiness, dependable service, and procedures. However, this study also reveals a promising finding: banks still have the potential for development, particularly in their response time, channel efficiency, fraud, and credibility, offering hope for the future of banking services.
