THE IMPACT OF PRODUCT QUALITY AND SERVICE QUALITY ON CUSTOMER SATISFACTION

This study investigates the influence of product quality and service quality on customer satisfaction at Istiqomah Mart. The research adopts a quantitative approach using survey methods, with 96 respondents selected through purposive sampling. Data collection was conducted using a structured questionnaire, and the analysis was performed using multiple regression analysis to determine the relationship between variables. The results indicate that both product quality and service quality have a significant positive impact on customer satisfaction. High-quality products and good service encourage customer trust and loyalty, leading to repeat purchases. However, the study also reveals a declining trend in customer satisfaction over time, as seen in the reduction of transaction frequency and unmet sales targets. This suggests that other factors beyond product and service quality may influence customer satisfaction, which were not examined in this research. Given these findings, the study suggests that future research should incorporate additional variables such as pricing strategy, promotional effectiveness, and store ambiance. Additionally, employing qualitative methods such as in-depth interviews could provide deeper insights into customer perceptions. For businesses, continuously improving product offerings and service standards is essential to maintaining customer satisfaction and strengthening market competitiveness.

Combination of banana fruit (Musa paradisiaca L.) in the production of pineapple wine in Vietnam

Fruit wine products derived from Vietnamese fruit sources are increasingly gaining popularity and preference among consumers in the market. However, the assessment of influencing factors and the optimization of fruit combinations in fruit wine production remain underexplored. The objective of this study was to survey the main factors affecting the quality of banana-pineapple wine after fermentation using commercial yeast strains. From there, appropriate technological parameters were determined to create bananapineapple wine products of high quality in terms of color, taste, and nutritional components. In this study, anaerobic fermentation utilizing the Saccharomyces cerevisiae yeast strain was employed to produce the wine product. At the same time, the resulting product had an average alcohol content of about 12 - 14% v/v. The fermentation process of banana-pineapple juice has been adjusted to mixing ratios of 5 - 10% and 15% v/v to create environmental conditions for yeast growth. In addition, pH was adjusted from 3.5 - 5.5, and total soluble solid from 20 - 28°Bx. After the fermentation process, the results showed that the fermentation solution with an initial mixing ratio of 15% v/v with an initial pH of 4.5 and a total soluble solid of 24°Bx would create the best quality fermented banana-pineapple wine product. The product had an ethanol content of 13.74% v/v. In green bananas, tannin precipitation occurs when combined with fruit protein, forming a precipitate. In wine production, after a fermentation period, this precipitate settles, contributing to a more precise final product and enhancing its quality. Therefore, an appropriate blending ratio is needed to achieve high-quality wine without compromising the yeast fermentation ability

The Development and Analysis of a Preliminary Electrodialysis Process for the Purification of Complex Lithium Solutions for the Production of Li2CO3 and LiOH

Direct lithium extraction (DLE) is emerging as a promising alternative to brine extraction although it requires further processing to obtain high-quality products suitable for various applications. This study focused on developing a process to concentrate and purify complex LiCl solutions obtained through direct lithium extraction (DLE). Two different chemical compositions of complex LiCl solutions were used, dividing the study into three stages. In the first part, lithium was concentrated to 1% by mass by evaporation. In the second, electrodialysis was used to alkalinize the LiCl solution and remove magnesium and calcium impurities under different current densities. The best results obtained were magnesium and calcium removals of 99.8% and 98.0%, respectively, and lithium recoveries of 99% and 96%. In the third stage, the selectivity of two different commercial cationic membranes (Nafion 117 and Neosepta CMS) was evaluated to separate Li+, K+, and Na+ cations under different current densities and volumetric flow rates. The Neosepta CMS membrane demonstrated higher lithium recovery. This study evaluated the quality of the purified lithium-rich solution and its potential use both in the production of Li2CO3 as well as in the electrochemical production of LiOH.

Structural Design of Tall Mass Timber Buildings

Following the Industrial Revolution, the construction of tall buildings has surged as a means of utilizing dense urban lands more efficiently. Previously, iron/steel and reinforced concrete were the primary structural materials used in tall buildings. However, the use of engineered mass timber as a structural material for tall buildings is steadily increasing due to its numerous benefits compared to its steel or reinforced concrete counterparts. These benefits include a lower carbon footprint, biophilic effects on occupant well-being, high-quality products due to reduced on-site manufacturing and labor, and shorter construction periods. Nevertheless, there are structural design considerations for tall mass timber buildings. This study first briefly examines the development of industrialized mass timber and investigates mass timber products. Mass timber encompasses a range of timber products, including glued laminated timber (GLT), cross-laminated timber (CLT), nail-laminated timber (NLT), dowel-laminated timber (DLT), laminated strand lumber (LSL), laminated veneer lumber (LVL), parallel strand lumber (PSL), and mass ply panel (MPP). It then explores the types of framing systems created with mass timber. These framing systems can be categorized according to their material usage as all-timber or hybrid systems and, according to load-bearing element usage, as post and beam, point-supported panels, wall and panel, and modular. Later, structural design considerations for tall mass timber structures are explained. After conducting case studies for the five tallest mass timber buildings worldwide, current approaches and research areas were identified for tall mass timber building structures. Keywords: tall buildings, mass timber, structural system, framing system

The Changes in Grassland Animal Husbandry and Herdsmen’s Life in the Qinghai Pastoral Area of China Based on the Perspective of Changes in the Grassland Property Rights System

Based on the historical background of the changes made to the grassland property rights system, the first part of this study restores the changes in property rights systems in six major autonomous counties of grassland animal husbandry production in Qinghai region, while the second part qualitatively analyzes the changes in grassland animal husbandry operations and herdsmen’s life under the changes in property rights. The results show that, with the reform of the property rights system, the range of livestock grazing has changed from large-scale nomadic grazing to regional rotational grazing. The herds are mainly yaks and Tibetan sheep, accounting for more than 90%, with the proportion of Tibetan sheep being higher than that of yaks. The numbers of total livestock and those on the market first rose and then declined, showing a dynamic balance in recent 10 years, while the number of breeding female animals has increased year by year. Artificial grass planting has gradually become popularized in pastoral areas. The time span of livestock supplementary feeding has increased and is more scientific, and the output value of animal husbandry has increased year by year, showing a strong peak associated with intensification. The proportion of the population engaged in animal husbandry has decreased gradually with increasing population in the region. The income sources of herdsmen have become more and more diversified and are increasing year by year, and the Engel coefficient presents a downward trend. The human environment in pastoral areas has improved. Based on the above analysis, suggestions for the sustainable and high-quality production of animal husbandry under the current grassland property rights system are put forward, as well as for the construction of green organic agricultural and livestock product export land in Qinghai Province.

Characterization of microbiota signatures in Iberian pig strains using machine learning algorithms

BackgroundThere is a growing interest in uncovering the factors that shape microbiome composition due to its association with complex phenotypic traits in livestock. Host genetic variation is increasingly recognized as a major factor influencing the microbiome. The Iberian pig breed, known for its high-quality meat products, includes various strains with recognized genetic and phenotypic variability. However, despite the microbiome’s known impact on pigs’ productive phenotypes such as meat quality traits, comparative analyses of gut microbial composition across Iberian pig strains are lacking. This study aims to explore the gut microbiota of two Iberian pig strains, Entrepelado (n = 74) and Retinto (n = 63), and their reciprocal crosses (n = 100), using machine learning (ML) models to identify key microbial taxa relevant for distinguishing their genetic backgrounds, which holds potential application in the pig industry. Nine ML algorithms, including tree-based, kernel-based, probabilistic, and linear algorithms, were used.ResultsBeta diversity analysis on 16 S rRNA microbiome data revealed compositional divergence among genetic, age and batch groups. ML models exploring maternal, paternal and heterosis effects showed varying levels of classification performance, with the paternal effect scenario being the best, achieving a mean Area Under the ROC curve (AUROC) of 0.74 using the Catboost (CB) algorithm. However, the most genetically distant animals, the purebreds, were more easily discriminated using the ML models. The classification of the two Iberian strains reached the highest mean AUROC of 0.83 using Support Vector Machine (SVM) model. The most relevant genera in this classification performance were Acetitomaculum, Butyricicoccus and Limosilactobacillus. All of which exhibited a relevant differential abundance between purebred animals using a Bayesian linear model.ConclusionsThe study confirms variations in gut microbiota among Iberian pig strains and their crosses, influenced by genetic and non-genetic factors. ML models, particularly CB and RF, as well as SVM in certain scenarios, combined with a feature selection process, effectively classified genetic groups based on microbiome data and identified key microbial taxa. These taxa were linked to short-chain fatty acids production and lipid metabolism, suggesting microbial composition differences may contribute to variations in fat-related traits among Iberian genetic groups.

The Impacts of Light Interception on Yield and Kernel Parameters in Hazelnut Production

Chile has become a significant producer of hazelnuts (Corylus avellana L.) due to its favorable conditions for off-season production to meet global market demand. Efficient light interception is crucial for optimizing the hazelnut yield and quality, as it directly influences the plant’s photosynthetic capacity. The goal was to assess the impact of intercepted photosynthetically active radiation (PAR) at upper, middle, and lower canopy levels in hazelnut trees grown at different planting densities and the canopy management of yield and quality parameters. The percentage of vain, sucker, double, bug, and healthy hazelnuts, including the number of fruits, total fruit weight, and grams per fruit was evaluated. The upper canopy levels intercepted the highest PAR, significantly enhancing the number and weight of fruits. The lower canopy levels received considerably less PAR, reducing the productivity. Production pruning in dense planting systems (5 × 3 m) improved the light penetration compared to a less dense planting density (5 × 6 m). Strong positive correlations were observed among PAR, fruit weight, and fruit number, emphasizing the importance of the light distribution within the canopy in hazelnut production. Production pruning and optimized planting densities are essential for maximizing light interception, improving yield, and ensuring high-quality hazelnut production.

Recent drying technologies used for drying poultry litter (principles, advantages and disadvantages): A comprehensive review.

Wet poultry litter creates an environment that accelerates the growth of bacteria and pathogens, leading to increased ammonia release. A practical way to reduce these adverse effects is heat treatment (drying). This work evaluated different methods for poultry litter drying and presented their principles, advantages, and disadvantages. Oven dryers are not recommended for continual drying due to their low energy efficiency, but decreasing water activity can prevent microbial growth. Rotary dryers provide homogeneous drying, but they are not suitable for drying fragile materials. Freeze drying preserves heat-sensitive ingredients, but the drying duration is high and classified as a high-cost drying technique. Microwave drying technology surpasses conventional methods in achieving both high product quality and energy efficiency. Solar drying emerges as the most economically viable, practical, and environmentally sound method for poultry litter desiccation. However, improperly controlled mass and heat transfer throughout the drying process can compromise product integrity. The use of combined dryers has not been thoroughly evaluated, although they may be more effective due to their synergistic results. This study is helpful for researchers who aim to reduce the adverse effects of poultry litter and manage it more effectively using heat treatment methods.

Micro N2-bubble-assisted esterification or crosslinking of corn starch by citric, lactic and malic acid: Facilitating the reaction medium under hydrodynamic cavitation.

This comparative study explores an innovative approach to enhance corn starch's resistant fraction through microbubble-assisted esterification. The modified starches showed reduced crystallinity and a higher degree of substitution (0.32 % to 0.49 %) in MAE compared to native esterified starches (0.24-0.37 %). FT-IR analysis identified a new absorption band at 1762 cm-1, signaling the CO stretching vibration associated with ester bonds formed between starch and L-malic, L-lactic, and L-citric acids. The resistant starch pattern produced by lactic acid significantly differed from citric and malic acid; RS fragments exhibited smooth surfaces and a compact, fused structure, particularly notable in LNC and LMC samples. Lactic acid, through esterification, reacted with starch hydroxyl groups, boosting RS levels and lowering rapidly digestible starch compared to citric and malic acids, acting as crosslinkers. The lack of peaks in the RVA pasting profiles confirmed successful crosslinking or esterification, significantly altering the starch's pasting characteristics. Hydrodynamic cavitation provides multiple benefits for physically modifying starch and providing a reaction medium for esterification or cross-linking. These include minimizing chemical input, reducing processing duration, and offering high selectivity and product quality, further enhancing its environmental sustainability.

Real-time monitoring of small changes in powder blends and ejected tablets in a low-dose formulation with 1 %w/w of active pharmaceutical ingredient using Raman and near-infrared spatially resolved spectroscopy within a tablet press.

This study used Raman and near-infrared (NIR) spectroscopy to monitor small real-time changes in powder blends and tablets in low-dose pharmaceutical formulations. The research aims to enhance process analytical technology (PAT) in pharmaceutical manufacturing, ensuring high-quality and uniform products with applications to produce drugs with narrow therapeutic indices (NTI). The study utilizes Raman and NIR spatially resolved spectroscopy (SRS) techniques to monitor a moderate cohesive material's active pharmaceutical ingredient (API) concentrations during manufacturing. The sampling locations were a bin blender for the batch blending procedure where the powder heterogeneity plays a significant role in product homogeneity, a feed frame of a tablet press where powder blend dynamics is critical to final product quality, and the outlet port of the tablet press where tablets immediately after ejection can be monitored in real-time. The study used semifine acetaminophen (APAP) as the API. Results indicated that Raman and NIR SRS could detect small API concentration changes as low as 0.50%w/w, demonstrating their sensitivity and utility in real-time monitoring. The findings support the feasibility of these techniques in ensuring tight process control and highlight the performance of reducing waste and optimizing manufacturing processes in line with quality by design principles. The results highlight the importance of residence time distribution (RTD) in understanding the flow of the materials and powder behavior within the tablet press feed frame. RTD analyses showed that both Raman and NIR SRS techniques could effectively track concentration changes and ensure uniformity in the powder blends and tablets with signal-to-noise ratios higher than 3, demonstrating the sensitivity of the methods to small API changes. The %RSD during a steady state of 250s (corresponding to 1.04kg of material at 15kg/h) for the step changes presented values of 6.74% at 0.50%w/w, 5.39% at 1.00%w/w, and 2.99% at 1.50%w/w for Raman predictions in powder blends within the feed frame and 15.46% at 0.50%w/w, 9.64% at 1.00%w/w, and 5.68% at 1.50%w/w for NIR SRS predictions of tablets ejected at the outlet port of the tablet press. In conclusion, this research demonstrates the potential of advanced spectroscopic techniques and data analysis in pharmaceutical manufacturing. By enabling precise real-time monitoring and control, these techniques contribute to higher-quality drug products, particularly NTI drugs, aligning with modern regulatory expectations and advancing pharmaceutical production technology.

Towards a digital twin of primary drying in lyophilization using coupled 3-D equipment CFD and 1-D vial-scale simulations.

A digital twin of lyophilization units was developed to facilitate the scale-up of the lyophilization process from the laboratory to the commercial scale. Our focus was on ensuring successful technology transfer for manufacture of high-quality drug products. Traditionally, lyophilization models have been specific either to the equipment or to the vial. In this study, we integrated the equipment and the vial models in a way that they mutually influenced each other via boundary conditions (two-way coupling). We conducted two sets of calculations. Firstly, we performed steady-state simulations using Computational Fluid Dynamics (CFD) to simulate an ice slab test, which helped determine the equipment capability curve. Secondly, we carried out transient, coupled simulations using a coupled 3-D CFD and 1-D vial scale simulation model to mimic the primary drying phase in a lyophilizer. Using the coupled 3-D CFD and 1-D vial scale model, we were able to determine the product temperature, the sublimation rate and the cycle time based on the temporal and spatial conditions in the lyophilizer. The coupled approach was then applied to capture the effects of process disturbances and failure conditions in the lyophilizer, which enables a more robust process design.

Fresh Pineapple Agronomy in the Republic of Benin: Recent Trends in Calcium Carbide Use and Producer Perceptions.

Pineapple (Ananas comosus (L.) Merrill) is among the main fruits produced in West Africa. This is also the case for the Republic of Benin, where pineapple fruit is regarded as an important crop for numerous producers in the Southern part of the country. However, crop production is constrained by various issues, the major one being poor yield caused by current agronomic practices. This has become a bottleneck that affects high-quality fruit production. The objective of this research was to (i) conduct a comprehensive analysis of the current fresh pineapple production system with a focus on trends over a decade and (ii) explore the compounds used to artificially induce flowering of pineapple plants, along with the perception of fresh pineapple producers on the use of calcium carbide (CaC2) on their health. Semi-structured interviews were conducted with 308 producers. Our results indicate that agronomic practices were diverse, with the involvement of more women in pineapple production over the last decade. A decrease in the involvement of young people was also observed. Cv. Sugarloaf remains the main cultivar grown, with a slight increase in cv. Smooth Cayenne. Increasing numbers of pineapple producers applied chemical fertilizers, with an increase in the use of potassium sulphate (K2SO4). Artificial flowering induction practices such as adding (i) petroleum/motor oil, (ii) cooking salt, (iii) liquid fertilizer ("Super Gro"), or (iv) urea to calcium carbide were reported, as well as health issues related to the use of calcium carbide. The research highlights the need for further studies on the use of alternatives to calcium carbide for artificial flowering induction in pineapple production in Benin.

This study explores the partnership experiences of patient and health care professional (HCP) subject matter experts (SMEs) in cocreating educational content and examines their reflections on how to better support educational partnerships in future initiatives. In this qualitative, exploratory study, semistructured interviews of patient and HCP SMEs were conducted between February and August 2022. Interviews were conducted with videoconferencing software, audio recorded, and transcribed verbatim. Interviews were analyzed using an iterative, inductive approach informed by reflexive thematic analysis. Eight patient SMEs and 6 HCP SMEs were interviewed. Three themes and 8 subthemes were developed to represent SMEs' experiences. The overarching themes included (1) building authentic partnerships, (2) developing equitable partnership processes, and (3) setting the stage for successful cocreation. Authentic partnerships were conceptualized as relationships that foster meaningful engagement, provide opportunities for learning and growing together, and require navigation of tensions and constraints. Equitable partnership processes included creating shared expectations and facilitating open and clear communication among partners. Participants discussed how future partnerships can benefit by embracing diversity and innovation, encouraging sustained engagement, and facilitating high-quality processes and products. The findings of this study highlight that positive cocreation experiences are characterized by building authentic partnerships, developing equitable partnership processes, and setting the stage for successful cocreation. Future work can build on these findings to further explore how to best foster cocreation within educational partnerships.

The relationship of some indicators of composition and quality of meat of the Angus bulls

The study of the formation of the composition and quality of livestock products is of scientific and practical importance. In this regard, the aim of the research was to determine the biological markers characterizing the quality indicators of muscle tissue of the Angus cattle. The object of the study was muscle samples of the rib eye of the Angus bulls (n = 157). The indicators of chemical, mineral, amino acid composition, quality indicators of meat were determined and correlations between them were calculated. pH 24 positively correlated with the content of chromium in meat. Positive correlations of water-holding capacity of meat (WHC) with the content of moisture, protein, ash, calcium, phosphorus, chromium, phenylalanine and negative ones with the content of fat and arginine were noted. Total amount of water-soluble antioxidants (TAWSA) positively correlates with the content of moisture, ash, macro- and microelements, cysteine, proline and negatively with the content of fat and some amino acids. The obtained results allow us to draw a conclusion about the formation of quality indicators of raw materials, which will help in developing methods for regulating and intravital formation of high-quality products of domestic cattle breeding.

A Study on Guidelines for Constructing Building Digital Twin Data

In South Korea, to systematically share and operate data related to the national level of the digital twin, a reference model standard for the National Digital Twin (NDT) concept was established in 2021. This was followed by the Korean Industrial Standards (KS) for buildings. Despite these efforts, the implementation of digital twin projects faces challenges owing to a low level of understanding of the standards and the absence of a standardized data construction process. Consequently, data construction that adheres to these standards is not being accomplished. Additionally, a lack of understanding of data models, semantic elements, and GML editing methods has led to the creation of appearance-focused data. To address these issues, this study proposes a digital twin data (building domain) construction guide that organizes geometric information, semantic information, and attribute information for building-related digital twin data components. This study aims to enable stakeholders to easily construct fundamental digital twin data in accordance with the standards, ensuring high-quality product creation that meets the requirements. Furthermore, the detailed data construction requirements defined in this guide will allow it to serve as a manual usable by both the public and private sectors. However, the proposed data model currently operates at a conceptual and logical level, which may limit its immediate applicability. Therefore, future research should include expert evaluations of the model and its transformation into a physical model that can be implemented and deployed on the relevant platform.
