The demand for specialists in the field of chemistry and chemical engineering capable of solving applied management tasks at industry enterprises with the aim of developing environmental protection chemical technologies became the reason for starting the training of such specialists within the walls of the Khmelnytskyi National University (KhNU). Educational program (ЕP) Chemical technologies and engineering is the only one for this specialty in Khmelnytskyi region, therefore the industry and regional contexts are the basis of the goal and objectives of training specialists in chemical technologies. One of the mandatory components of the master's training in chemical technologies and engineering is "Quality of raw materials and products of chemical technologies". As you know, the lion's share of industrial production in our country is the production and processing of agricultural products, and Khmelnytskyi region is traditionally one of the leaders in the production of grain crops throughout Ukraine. The following factors affect the quality of grain in the Khmelnytskyi region. A wide range of varieties of grain crops adapted to local conditions are grown in the region. Modern growing technologies, use of fertilizers and plant protection products contribute to obtaining high-quality grain. A favorable climate contributes to the accumulation of nutrients in grain. Fertile soils of the region ensure high yield and quality of grain. Regular control of grain quality in the Khmelnytsky region is subject to constant control with the help of laboratory tests. Grain produced in the region, as a rule, meets the requirements of state standards of Ukraine and international standards. Thus, іn order to ensure the high quality of grain indicators, it is necessary to introduce a system of ensuring and controlling the quality of raw materials and products of the agricultural industry at a sufficiently high level. For these reasons, it is expedient at the department of chemistry and chemical engineering within the educational component "Quality of raw materials and products of chemical technologies" ЕР of the master's level to participate, among other tasks, in the examination and quality control of cereals. This applies both to the study of the regulatory framework for grain quality assurance and control, and to laboratory research methods, most of which are possible with the available material and technical support of the Department of Chemistry and Chemical Engineering.

Talent shortages among skilled trades workers are a growing global concern in many of the world’s largest economies. In the United States (U.S.), these shortages could cost as much as $2.5 trillion with 2.4 million positions unfilled between 2018 and 2028. Consequences for employers and consumers include reduced competitiveness, productivity, and higher turnover. Engagement of employees in their jobs has become important in industry sectors experiencing these shortages. Several calls have been made to examine antecedent human resource development interventions, like managerial coaching, and other mediating mechanisms that might influence engagement. Feedback, often a provision of managerial coaching, may enable employees to craft their jobs. Thus, job crafting may explain how managerial coaching can help employees to craft their jobs to be more meaningful and engaging. Therefore, this study examined the mediating effect of job crafting on the relationship between managerial coaching and job engagement among electricians in the U.S. skilled trades. A quantitative, half-longitudinal survey design with two paper surveys administered at two distinct time periods in a skilled trades organization was employed. Data from 292 matched surveys were analysed. Findings support job crafting as a full mediator between managerial coaching and job engagement. Implications and future research pathways are provided.

Event Abstract Back to Event Sulfated Glycopolymers for glycosaminoglycan mimics and nanomedicine Yoshiko Miura1, Tomohiro Fukuda2 and Yu Hoshino1 1 Kyushu University, Department of Chemical Engineering, Japan 2 National Institute of Technology, Toyama college, Department of Applied Chemistry and Chemical Engineering, Japan Glycosaminoglycans (GAGs) are polysaccharides found in living systems that play key roles in biological activities and also function as polyelectrolyte. The preparation of GAGs is important in view of biomaterials development, and total syntheses have been energetically studied by many researchers. However, it is difficult to attain the total syntheses of GAGs due to the complex chemical structure and large molecular sizes. We investigated the preparation GAGs mimic polymer and application of nanomedicine via glycopolymer methods. We tried to reconstruct the function of GAGs by glycopolymers of regioselective sulfated saccharides. Glycopolymers provides the strong binding based on the multivalency. In addition, glycopolymer libraries are easily prepared by the radical polymerization. We prepared the phenyl acrylamides with sulfonated N-acetyl glucosamines (GlcNAc) of 6-sulfo-. 3-sulfo-, 4-sulfo and 3,4, 6-sulfo-GlcNAc. The monomers of sulfonated GlcNAc were synthesized by glycosylation, regioselective sulfonation of GlcNAc and condensation with acrylate. The monomers were polymerized with other vinyl monomers to prepare the glycopolymer and glyconanoparticles (Figure 1). We investigated the affinities of the GAGs mimic glycopolymers with pathogen proteins. The glycopolymers with 6-sulfo-GlcNAc exhibited the inhibitory effect on Alzheimer’s amyloid beta peptides. The inhibitory effects depended on the sugar ratio and the molecular weights of the polymers. The GAGs mimic array was prepared to analyze the interaction with amyloid beta peptides. The enzyme (b-secretase) for Alzheimer disease was also inhibited by the GAGs mimic polymers. The nanoparticle with GAGs mimic monomer was also prepared to capture the specific proteins. These results showed the usefulness of the glycopolymers comparing to the real GAGs. The glycopolymers are applicable to the many kinds of materials including synthetic polymer, particle, nanoparticles and thin layer formations, which are useful for bionanomaterial and nanomedicine fabrications.

Event Abstract Back to Event A mechanically robust injectable hydrogel scaffold for adipose-derived stem cell delivery for the treatment of peripheral arterial disease Stuart Young1, Lauren E. Flynn2 and Brian G. Amsden1 1 Queen's University, Department of Chemical Engineering, Canada 2 University of Western Ontario, Department of Chemical and Biochemical Engineering, Canada Introduction: Peripheral arterial disease can lead to critical limb ischemia with high risks of amputation and mortality. A promising treatment involves delivering adipose-derived stem cells (ASCs) to stimulate revascularization and functional recovery. However, when delivered via intramuscular injection in saline, substantial ASC loss occurs. To improve ASC retention and survival, a modular delivery gel was developed composed of: i) methacrylated glycol chitosan (MGC) functionalized with GGGGRGDS, and ii) a diacrylate triblock copolymer of poly(ethylene glycol) (PEG) and poly(trimethylene carbonate) (PTMC) to improve mechanical robustness. A thermal initiator system of ammonium persulfate (APS) and N,N,N′,N′-tetramethylethylenediamine (TEMED) was optimized for in situ gelation following injectable delivery. Methods: MGC was prepared as previously reported[1]. The N terminus of GGGGRGDS peptide was acrylated and conjugated to MGC via Michael addition. Acrylated PEG-PTMC of varying block lengths was prepared by ring-opening polymerization of TMC initiated by PEG (4, 10, or 20 kg·mol-1) (TMC:PEG MW = 1:10 – 1:2)) using HCl as a monomer activator, followed by reaction with acryloyl chloride. Polymer structure and functionalization were confirmed by 1H NMR and GPC. To form gels, APS and TEMED (2.5 to 10 mM) were added to solutions of MGC and PEG-PTMC. Initiation sensitivity and crosslinking time were assessed by rheometry at 20 °C and 37°C. Gels were equilibrated in PBS, after which the swelling ratio and mechanical properties were measured. Isolated bovine ASCs[2], expanded to passage 2, were suspended in the pre-polymer solutions. APS/TEMED was added, and the suspension injected via 25G needle into molds and crosslinked by heating (37°C). ASC viability (LIVE/DEAD staining) and metabolic activity (MTT assay) were monitored over 7 days. Results: The MGC had a 5% degree of methacrylation and 5% degree of peptide functionalization, while the PEG-PTMC had > 99% acrylation. Pre-polymer solutions showed no gelation over 10 min at 20 °C (Fig. 1a). Upon heating, gelation time was directly related to initiator concentration (Fig. 1b). The swelling, equilibrium compressive modulus, and maximum strain of PEG-PTMC hydrogels was dependent on the overall molecular weight and PEG/PTMC ratio (Fig. 2). By blending MGC with PEG-PTMC, gel stiffness was significantly reduced to the range of native tissue (~10-15 kPa), while improving elastic resiliency under dynamic loading. Further, the metabolic activity of encapsulated ASCs was maintained over 7 d of culture. Discussion: Blending of MGC with PEG-PTMC facilitated adjustment of gel mechanical properties while improving resiliency under dynamic loading. The APS/TEMED crosslinking approach provided an injectable delivery method with high stimuli sensitivity. Sustained ASC metabolic activity in culture suggests the gel could promote ASC survival and retention, thereby promoting their regenerative effects in ischemic regions.

Skilled trades play a pivotal role in industrial productivity and craftsmanship, yet workers in these professions face occupational hazards, including traumatic amputations. Existing prosthetic solutions often inadequately address the needs of trade workers, leading to challenges in returning to work effectively. This paper explores the development of an Electromyography (EMG) wire feeder designed to assist hand amputees in TIG welding, emblematic of the broader investigation into prosthetic technology. Recognizing the critical gap in current prosthetic solutions for trade workers, this research aims to develop solutions tailored to the demands of labor-intensive industries. By exploring alternative control methods such as force myography, which offers robust control mechanisms less susceptible to environmental factors, this study seeks to enhance prosthetic usability in skilled trades. Additionally, efforts are directed towards simplifying prosthetic control systems, ensuring reliability and adaptability to task-specific needs. Through the convergence of engineering ingenuity and prosthetic rehabilitation, this research endeavors to transform the lives of individuals in skilled trades, enabling them to reclaim their livelihoods effectively.
