Educating Pediatric Nursing Students on Coping Strategies When Dealing with The Loss of a Child Patient
No full textRecord ID: 304
Program Affiliation: Capstone
Presentation Type: Poster
Abstract: Almost 75% of pediatric nurses will experience the loss of a child patient within their first year of working. No specific training is provided to nursing students coping with the loss of a patient. The purpose of this project was to provide information to students on positive coping strategies they can use with the focus on the benefits of group debrief sessions as well as individualized personal strategies. We conducted a literature search that consisted of current evidence published within the last seven years and created a PowerPoint educational session to present to a pediatric nursing class. This content outlined the purpose of our research, how the research applies to students, the various types of coping strategies, resources available, and the strategies that proved to be most beneficial when coping with the death of a patient. The pre and post-tests will assess the knowledge of students before and after our presentation. Ultimately, they will assess their confidence level when seeking support, identifying healthy coping strategies, and their understanding of bereavement. Results of this project are pending. The outcome of the education will help future nurses have a better understanding on how to cope with the loss of a patient. Students will be able to identify effective coping strategies such as group debriefing and understand the benefits utilizing this strategy will grant them rather than less effective strategies that only involve the individual alone

The goal was to test for signs of synchronization and coordination in the participants successive judgments. Previous research established entrainment in an unperson version of the task. This study was aimed at assessing the degree to which coordination is evident in a spatially distributed online version of the task. Spectral or Fourier analysis is used to test for coordination
Application of Ultrasound in Eco-friendly Fatliquoring of Leather
No full textThis article describes the effect of ultrasound on fatliquoring of leather. Preparations of fatliquor-emulsions as well as fatliquoring of leathers were carried out in presence of ultrasound. Ultrasound aids in reducing the size of fatliquor emulsion and increasing fat content of leather. It was found that the particle size of fatliquor emulsion was reduced by more than 22% and fat contents of leather were increased up to 40% due to using ultrasound. Moreover, smooth penetration and uniform distribution of fat in the processed leathers were observed. Physical properties of both ultrasoundassisted fatliquored leather and conventionally fatliquored leather were also studied in detail. Tensile strength, stitch tearing strength, tongue tearing strength, grain crack load, ball bursting load, Bauman tear strength, color fastness and perspiration of ultrasound assisted fatliquored leather were better compared to that of without ultrasound. 
Decoding Source of Leather Odor: A Quantitative Analysis with Heracles NEO
No full textLeather products are widely used in our daily life and in close contact with users, but the pleasant feeling during its usage is severely affected by the odor volatilized from the leather surface. In this study, a quantitative analysis method to investigate the differences in the odor profiles among four types of leather was proposed. The primary olfactory constituents of four leather types were examined by Heracles NEO ultra-fast gas-phase electronic nose, including Principal Component Analysis (PCA) and Discriminant Factor Analysis (DFA). In chrome-tanned cattle hide leather, the substance with the highest content was 2,4-Dinitrotoluene, while methyl dodecanoate was the predominant compound in chromefree cattle hide leather. Notably, chrome-tanned sheepskin leather exhibited higher levels of dodecanal, clopyralid, n-octylbenzene, propyl cinnamate, and 3-methylhexadecane. Similarly, chrome-free sheepskin leather contained higher levels of dodecanal, clopyralid, n-octylbenzene, propyl cinnamate, 3-methylhexadecane, and tetradecanol. These findings indicate that each of the four types of leather possesses distinctive compounds, while also sharing common compounds. Furthermore, the results indicate that radar plots along with PCA and DFA analyses can effectively differentiate between the four types of leather
Lightweight Detection Model for Animal Wet-Blue Hide Surface Defects Based on Yolov5s
No full textIn the process of animal leather processing, the surface damage of wet-blue hides restricts the quality of leather products. To ensure the efficiency and quality of animal leather processing, a lightweight model for detecting surface defects on wet-blue hides based on optimized YOLOv5s is proposed. The new model adopts the lightweight EfficientNetV2 network to extract surface defect features and incorporates a spatial pyramid pooling–fast (SPPF) structure at the end of the network to obtain features at different scales. Efficient multi-scale attention (EMA) was embedded in the bottom-up structure of the Neck section to achieve comprehensive feature extraction and retention, ensuring that spatial semantic features are adequately distributed in each feature. A dataset of wet-blue hide defects was constructed and used to verify the performance of the new model. the experimental results show that, the new model is superior to the commonly used classical detection models. The precision rates for detecting three types of leather surface defects, namely imprint, puncture, and breakage, are 86.5%, 95.3%, and 87.9%, respectively. These results can provide technical support for research of surface damage detection in other leather processing applications
Enhancement of Mechanical and Thermal Insulation Properties of Polyvinyl Chloride Foam Using Leather Shavings
No full textThe global production of leather shavings (LSs) amounts to millions of tons annually, posing significant challenges in terms of resource waste and environmental pollution if not effectively managed. This study explores the utilization of LSs by fabricating modified leather fibers (MLFs) as reinforcing fillers to enhance the mechanical and thermal insulation properties of polyvinyl chloride (PVC) foams. The process involved pulverizing LSs and modifying them with a polyethylene glycol–isophorone diisocyanate (PEG–IPDI) prepolymer to create MLF. This MLF was then incorporated into PVC to produce MLF/PVC foam. The PEG–IPDI prepolymer modification aligned the surface free energy of MLF (33.82 ± 1.97 mJ/m2) with that of PVC (31.08 ± 3.65 mJ/m2), thereby improving their interfacial compatibility and imparting thermal energy storage capacity to the MLF. The resulting MLF/PVC foam exhibited enhancements in compressive strength and modulus, showing increases of 93.7% and 165.8%, respectively, compared to pure PVC foam. Furthermore, MLF/PVC foam demonstrated a slower surface temperature increase when heated using a heating plate at 110°C compared to pure PVC foam. These findings indicate that MLF enhances the mechanical and thermal insulation properties of PVC foams, primarily due to the improved foaming and thermal storage capacities imparted by the MLF
Influence of Polyurethane Binders on the Surface Properties of Finished Leathers: Part 1 – Function as a Sealing Coat
No full textFinishing is the final stage of the leather-making process, where the surface of the leather is enhanced to improve its durability, appearance, and texture. The sealing coat (used predominantly in corrected grain leathers for leather accessories and footwear industries) is the first step that forms the bottom layer of the leather finishing film before the base coat. The goal of the sealing coat is to keep the leather surface reactive and prevent the pigmented base coat from sinking completely into the grain of the leather. The chemicals used in the sealing coat provide the leather surface with a charge and condition (addition of oil/fat and/or polyurethane -PU) to ensure that the chemicals (pigments, binders, and other additives) used in the base coat of the finishing process are not completely absorbed into the grain layer of the crust leather. In the present study, the influence of PU as an additive to the sealing coat formulation was evaluated through measurement of surface properties, such as contact angle, surface energy, and work of adhesion. The values of the contact angle between the liquids (water/ dimethyl sulfoxide/ hexadecane) and the leather surface were used to evaluate the leather’s surface energy and work of adhesion. The water contact angle of the uncoated crust, cationic oil ground (COG)-coated crust, and COG-PU-coated crust was measured as 77.3, 93.6, and 109.0 degrees respectively. The increase in contact angle indicates an increase in the hydrophobicity of the leather’s surface on coating with COG and COG+PU. The surface energy component (γs) of the crust leather surface without coating, COG-coated, and COG-PU-coated leathers were 35.2, 28.3, and 24.8 m/Nm, while the work of adhesion of the above leathers for water were 88.8, 68.2, and 49.1 mJm-2, respectively. The experimental values indicated that PU plays an important role as an additive to the sealing coat and enhances the required properties in the finishing process for the desired final leather
An Alternative Natural Dyestuff for Leather Dyeing: Red Beetroot (Beta Vulgaris L.)
No full textIncreasing awareness of environment and human health, the demand/interest for using of natural products from renewable biological sources has increased in terms of sustainable production recently. In line with this idea, natural dyes are attracting more and more attention due to their advantages such as being obtained from natural/renewable resources, being less harmful to the environment and human health, and degradability in nature. In the present study, the aim was to investigate possible use of red beetroot concentrate as a natural dyestuff in leather making and evaluate its dyeing performance. For this purpose, crust leathers tanned with different tanning agents (chrome, Tara, aluminum/synthetic) were dyed with red beetroot. Furthermore, CuSO4.5H2O (copper sulfate), KAl(SO4)2.12H2O (potassium aluminum sulfate) and FeSO4.7H2O (iron sulfate) mordants were used in pre- and post- mordanting applications so as to obtain different colors and improve the fastness properties of the dyed leathers. Dyestuff consumptions, dry/wet rubbing fastness values and the colors imparted to leathers were determined. Dyestuff consumptions for Cr tanned leathers were better than other leather types as expected. However, among mordant treatments use of CuSO4.5H2O mordant resulted notably increments (59.8%-62.2%) in dyestuff consumptions of Tara and aluminum/synthetic tanned leathers. The values of dry/wet rubbing fastness of leathers were quite satisfactory. Red beetroot and mordants gained different color tones to different types of tanned leathers and the most conspicuous variation was obtained with FeSO4.7H2O mordant. It was inferred that red beetroot concentrate can be used directly as a source of natural dyestuff in leather dyeing without necessitating any extraction process
