Rola komitetów rewitalizacji w procesie rewitalizacji na przykładzie województwa wielkopolskieg
Authors: Dziarmakowska Natalia
Published: March 2024

Partycypacja społeczna powinna stanowić podstawę działań rewitalizacyjnych. W literaturze fachowej wyróżnia się jej różne poziomy i formy. W Polsce za najwyższą formę udziału społeczeństwa w procesie rewitalizacji należy uznać komitet rewitalizacji. Stanowi on najważniejsze ciało sprawujące społeczną kontrolę nad wszystkimi elementami procesu rewitalizacji, a także daje interesariuszom szansę na wywieranie realnego wpływu na przebieg działań rewitalizacyjnych. Liczne opracowania i raporty wykazują jednak, że ciało to jest wciąż niewystarczająco praktykowanym instrumentem partycypacji społecznej. Celem artykułu jest ocena roli oraz zakresu aktywności komitetów rewitalizacji i ich odpowiedników w procesie rewitalizacji na przykładzie województwa wielkopolskiego. W badaniu wykorzystano metodę analizy danych zastanych i badania ankietowego.
Zur Entwicklung der Interpunktion in der Luther-Bibel
Authors: Rinas Karsten
Published: March 2024

This study examines the development of punctuation in the Luther Bible in the period between 1522 and 2017 based on a passage from the Gospel of Matthew in 82 editions. The analysis is quantitative, qualitative, and at the same time hermeneutical: by repeatedly recalling the original printings, the aim is to capture all the relevant factors for historical punctuation. Among other things, aspects of the general text structure and line breaks are taken into account. From a syntactic point of view, various special cases are discussed, such as punctuation in non-sentential prepositional groups and in infinitives to block misinterpretation, but also the lack of punctuation in ›incorporated‹ main clauses. Furthermore, it is shown how the modern syntax-based punctuation since the middle of the 19th century runs counter Luther’s listener-oriented sentence construction.
Evidentialität in autochthonen altgermanischen Schriftdenkmälern im Vergleich zur deutschen Gegenwartssprache
Authors: Kotin Michail L.
Published: March 2024

The paper presents a diachronically based concept of the evidential function in the language. It is argued for a specific discourse evidentiality of the oldest autochthonic German poetry which encoded not epistemic interpretations of outer sources of information, but rather a strong guarantee for the truth of reported events. The origins of this kind of evidentiality can be found both in ontogenesis of a given language, e. g. language acquisition, and in its phylogenesis.
A new approach for heart disease detection using Motif transform-based CWT’s time-frequency images with DenseNet deep transfer learning methods
Authors: Tekin Hazret , Kaya Yılmaz
Published: March 2024

Objectives: Electrocardiogram (ECG) signals are extensively utilized in the identification and assessment of diverse cardiac conditions, including congestive heart failure (CHF) and cardiac arrhythmias (ARR), which present potential hazards to human health. With the aim of facilitating disease diagnosis and assessment, advanced computer-aided systems are being developed to analyze ECG signals. Methods: This study proposes a state-of-the-art ECG data pattern recognition algorithm based on Continuous Wavelet Transform (CWT) as a novel signal preprocessing model. The Motif Transformation (MT) method was devised to diminish the drawbacks and limitations inherent in the CWT, such as the issue of boundary effects, limited localization in time and frequency, and overfitting conditions. This transformation technique facilitates the formation of diverse patterns (motifs) within the signals. The patterns (motifs) are constructed by comparing the amplitudes of each individual sample value in the ECG signals in terms of their largeness and smallness. In the subsequent stage, the obtained one-dimensional signals from the MT transformation were subjected to CWT to obtain scalogram images. In the last stage, the obtained scalogram images were subjected to classification using DenseNET deep transfer learning techniques. Results and Conclusions: The combined approach of MT + CWT + DenseNET yielded an impressive success rate of 99.31 %.
Modeling of reaction–desorption process by core–shell particles dispersed in continuously stirred tank reactor (CSTR)
Authors: Cho Young-Sang , Nguyen Hoai-Han
Published: March 2024

Transient responses of reaction–desorption process were predicted from mathematical solutions of modeling equations for CSTR (continuously stirred tank reactor) containing core–shell adsorbent particles. Analytical solutions on the core–shell particles were derived for core–shell spherical, cylindrical, and slab-type morphologies, assuming inert-cores. Unlike continuous adsorber, CSTRs for reaction–desorption process containing spherical particles exhibited the slowest reduction rate of concentration of adsorbate, because the amount of adsorbed component on the particles is the largest among three kinds of particle shapes. Factors affecting the transient concentration in bulk medium of reaction–desorption process were investigated by adjusting inert-core thickness, inlet flow rate, initial concentration of reactant in inflow stream, amount of adsorbent, and Thiele modulus. Concentration profile inside the particles as well as average intra-particle concentration could be also predicted for comparison with bulk concentration of CSTR. For non-linear isotherm and non-linear reaction kinetics, concentration of active component could be predicted by solving non-linear coupled differential equation using finite element method. For connected CSTRs in series, systems of reaction-diffusion equations were solved by finite element method to study the effect of number of connected reactors. When the number of reactors was sufficiently large, the reactor system could be approximated to fixed bed reactor for reaction–desorption process.
Comprehensive performance evaluation based on electromagnetic shielding properties of the weft-knitted fabrics made by stainless steel/cotton blended yarn
Authors: Li Ning , Liu Tianjiao , Tian Mengqi , Duan Junrui , Yao Mu , Sun Runjun
Published: March 2024

Electromagnetic shielding (EMS) fabric is an effective way to prevent electromagnetic (EM) radiation. However, the research about mechanism analysis of the fabrics’ structure, EM wave (EMW) incident direction, and EMW frequency on the EMS properties of knitted fabrics is discordant at present. Meanwhile, researchers are focused on improving the EMS efficiency of the fabric but rarely discussed the thermal-wet comfort of the fabric. Therefore, in this study a series of weft-knitted fabrics within stainless steel/cotton (30/70) blended yarns were knitted, and the effects of EMW incident direction, stitches, loop lengths, and frequency on EMS effectiveness (EMSE) were analyzed. Meanwhile, the EMS property, warmth retention property, air permeability, moisture permeability, and bursting strength were selected as the evaluation index to evaluate the comprehensive properties of the fabrics by fuzzy mathematics. The results showed that all factors had different degrees of influence on EMSE, and the weft inlay stitch had both the functionality and thermal-wet comfort, which was excellent EMSE in knitted fabric. These results are expected to provide a reference to the design of EMS weft-knitted fabrics.
A review of theories, pedagogies and vocabulary learning tasks of English vocabulary learning apps for Chinese EFL learners
Authors: Li Congxin
Published: March 2024

Among a growing body of mobile-assisted-language-learning (MALL) studies, vocabulary application (app) studies have comprised an unprecedented proportion. However, there has been insufficient discussion about the fundamental language learning theories and pedagogies underlying app design. This study aims to fill this gap by conceptualising and theorising the design of English vocabulary learning apps with a focused analysis of their task features with relation to vocabulary learning strategies (VLS), language learning theories and pedagogies. Four Chinese–English vocabulary learning apps were purposively sampled. The results show that the design of the four evaluated apps incorporates principles from four distinct language learning theories: behaviourism, input-based emergentism, sociocultural theory and information and cognitive processing theories. The four apps’ tasks and user interfaces were analysed to generate codes for task classification. These task-related codes were further classified under the categories of Schmitt’s VLS taxonomy and under pedagogical categories based on the definitions of pedagogies and VLS codes and the intended classroom practice. Vocabulary pedagogies were further linked with theories to shed light on the theoretical foundations for the apps’ use of learning tasks and VLS as well as on the pedagogical prospects of vocabulary learning apps.
Isotopic effects on in-plane hyperbolic phonon polaritons in MoO3

Published: March 2024

Hyperbolic phonon polaritons (HPhPs), hybrids of light and lattice vibrations in polar dielectric crystals, empower nanophotonic applications by enabling the confinement and manipulation of light at the nanoscale. Molybdenum trioxide (α-MoO3) is a naturally hyperbolic material, meaning that its dielectric function deterministically controls the directional propagation of in-plane HPhPs within its reststrahlen bands. Strategies such as substrate engineering, nano- and hetero-structuring, and isotopic enrichment are being developed to alter the intrinsic dielectric functions of natural hyperbolic materials and to control the confinement and propagation of HPhPs. Since isotopic disorder can limit phonon-based processes such as HPhPs, here we synthesize isotopically enriched 92MoO3 (92Mo: 99.93 %) and 100MoO3 (100Mo: 99.01 %) crystals to tune the properties and dispersion of HPhPs with respect to natural α-MoO3, which is composed of seven stable Mo isotopes. Real-space, near-field maps measured with the photothermal induced resonance (PTIR) technique enable comparisons of in-plane HPhPs in α-MoO3 and isotopically enriched analogs within a reststrahlen band (≈820 cm−1 to ≈972 cm−1). Results show that isotopic enrichment (e.g., 92MoO3 and 100MoO3) alters the dielectric function, shifting the HPhP dispersion (HPhP angular wavenumber × thickness vs. IR frequency) by ≈−7 % and ≈+9 %, respectively, and changes the HPhP group velocities by ≈±12 %, while the lifetimes (≈3 ps) in 92MoO3 were found to be slightly improved (≈20 %). The latter improvement is attributed to a decrease in isotopic disorder. Altogether, isotopic enrichment was found to offer fine control over the properties that determine the anisotropic in-plane propagation of HPhPs in α-MoO3, which is essential to its implementation in nanophotonic applications.
Climate change and adaptive strategies on viticulture (Vitis spp.)
Authors: Atak Arif
Published: March 2024

Climate change has many negative effects on the viticulture sector, as it does in all sectors. In recent years, global climate change has also shown its effect in the form of sudden climatic events. There is an urgent need to develop preventive/protective activities for all plant species in order to prevent the increasing world population from being negatively affected by many negative consequences of climate change such as increasing temperatures, drought, floods, and sudden climatic events. Grape industry is among the sectors that feel the negative effects of climate change the most, and this effect is increasing every year. Along with global warming, there are also important problems in accessing water. Particularly, there is a need to develop cultivars that are more resistant to drought stress and to make applications that will protect grapevine plants from drought stress. One of the most important issues to be overcome is to develop new cultivars that can withstand different stress conditions and to use them more in production. In addition, environmental and human health awareness is increasing day by day. Adaptation strategies to be taken against the negative effects of climate change and the studies to be carried out, as well as the use of new environmentally friendly varieties (requiring less input costs) to be developed in accordance with the sustainable agriculture model, will make significant contributions to protecting both the environment and human health.
Information Content of Inflation Expectations: A Copula-Based Model
Authors: Ardakani Omid M.
Published: March 2024

This paper introduces a holistic framework that integrates copula modeling and information-theoretic measures to examine the information content of inflation expectations. Copulas are used to capture the dynamic dependence between inflation and expectations, accounting for extreme events and tail dependence. Information-theoretic measures are employed to quantify the information that expectations provide about inflation. Theoretical results establish a link between copula entropy and mutual information, propose a lower bound for copula entropy, and provide a practical tool for central banks to anchor expectations to achieve inflation targets. Empirical findings reveal higher uncertainty in the tails of the joint distribution and underscore the meaningful information carried by expected inflation for forecasting inflation, particularly with shorter-term expectations.

Published: March 2024

Due to recent progress in human-machine interaction the development of interfaces ensuring a safe collaboration between handling devices and workers is gaining in importance and impact to the industry field. For an adequate operation, combined sensing and actuation capabilities are sufficient for interaction units. Smart materials like dielectric elastomers (DEs) are predestinated for integrated multi-functional applications. DEs are lightweight, high energy density and highly stretchable transducers suitable for many different operation areas, like movement tracking, force sensing, haptic feedback and sound generation and can be used to develop highly integrated textile-based user interfaces. This paper shows first results on the development of a novel intelligent glove prototype based on DE elements. The main focus of this investigation lies on DE-based integrated joint angle and force measurement units as well on a cost-efficient and slim sensing electronic. By embedding the resulting system in an Industry 4.0 environment, an adaptive assistance tool can be developed. The resulting system can be used to monitor the desired motion of a worker and to respond with a corresponding haptic feedback, which depends on the specific interaction task. This makes the resulting system a novel, portable assistant tool for industrial environments.

Published: March 2024

In this research project, a computational assessment of the molecular structure of Ipriflavone (IP) in the gaseous phase was done based on density functional theory (DFT). In the realm of theory, the standard basis set B3LYP is a collection of functions used with linear combinations to produce molecular orbitals, making it simple to compute the molecular structure related to the given compound. With the time-dependent DFT approach, the UV spectra obtained for various solvents were used for examining the electronic transport features. A three-dimensional representation of the molecules that shows the charge distributions and charge-related characteristics of the molecule has the acronym the electrostatic potential map. The frontier molecular orbitals (FMO) confirmed the compound’s stability and good reactivity. Hyperpolarizability calculations were performed with good non-linear optical (NLO) potent. Natural bond orbital (NBO) analysis was used to explore charge delocalization and the compound’s stability. Topological investigations have been identified to clarify the bonding zones, weakest contacts, and electron energy density. Drug likeness studies were used to promote bioactivities. The outcome of docking tests shows that the ligand under investigation is beneficial at preventing bone loss-osteoporosis. To sum up, this work provides a comprehensive analysis that combines spectroscopic and quantum computational techniques to assess the effect of specific medicinal compounds on solvation and metabolic activity. Strategies for subsequent studies can thus greatly benefit from the knowledge obtained.

Encoding of visual objects in the human medial temporal lobe
Authors: Wang Yue , Cao Runnan , Wang Shuo
Published: March 2024

The human medial temporal lobe (MTL) plays a crucial role in recognizing visual objects, a key cognitive function that relies on the formation of semantic representations. Nonetheless, it remains unknown how visual information of general objects is translated into semantic representations in the MTL. Furthermore, the debate about whether the human MTL is involved in perception has endured for a long time. To address these questions, we investigated three distinct models of neural object coding—semantic coding, axis-based feature coding, and region-based feature coding—in each subregion of the MTL, using high-resolution fMRI in two male and six female participants. Our findings revealed the presence of semantic coding throughout the MTL, with a higher prevalence observed in the parahippocampal cortex (PHC) and perirhinal cortex (PRC), while axis coding and region coding were primarily observed in the earlier regions of the MTL. Moreover, we demonstrated that voxels exhibiting axis coding supported the transition to region coding and contained information relevant to semantic coding. Together, by providing a detailed characterization of neural object coding schemes and offering a comprehensive summary of visual coding information for each MTL subregion, our results not only emphasize a clear role of the MTL in perceptual processing but also shed light on the translation of perception-driven representations of visual features into memory-driven representations of semantics along the MTL processing pathway.

Significance StatementIn this study, we delved into the mechanisms underlying visual object recognition within the human medial temporal lobe (MTL), a pivotal region known for its role in the formation of semantic representations crucial for memory. In particular, the translation of visual information into semantic representations within the MTL has remained unclear, and the enduring debate regarding the involvement of the human MTL in perception has persisted. To address these questions, we comprehensively examined distinct neural object coding models across each subregion of the MTL, leveraging high-resolution fMRI. We also showed transition of information between object coding models and across MTL subregions. Our findings significantly contributes to advancing our understanding of the intricate pathway involved in visual object coding.

Published: March 2024

This research investigates the effects of using rosehip infusion as a marinade on the physicochemical, technological, textural properties, and oxidative stability of turkey breast meat. The chemical composition, technological properties, color and textural parameters, pH, and lipid oxidation of marinated turkey samples were determined. Marinades used in reformulated groups were prepared with rosehip at different concentrations (10 g (R1), 15 g (R2), and 20 g (R3)/150 mL). Rosehip-infused marinated samples exhibited lower pH, altered color parameters, enhanced water holding capacity and cooking yield, and increased marinade uptake (especially in R3). In texture analysis, it was observed that the hardness of the samples decreased, while the values of cohesiveness and springiness increased. Notably, rosehip infusion demonstrated antioxidative effects, lowering TBARS values compared to the control. In summary, marination with rosehip infusion presents a promising method to improve the technological and textural qualities of turkey breast meat while protecting against lipid oxidation.
IGF-2-mediated hypoglycemia: a case series and review of the medical therapies for refractory hypoglycemia
Authors: Vu Albert , Chik Constance , Kwong Sarah
Published: March 2024

Non-islet cell tumour hypoglycemia (NICTH), typically mediated by insulin-like growth factor 2 (IGF-2), is a rare but highly morbid paraneoplastic syndrome associated with tumours of mesenchymal or epithelial origin. Outside of dextrose administration and dietary modification which provide transient relief of hypoglycemia, resection of the underlying tumour is the only known cure for NICTH. Available medical therapies to manage hypoglycemia include glucocorticoids, recombinant growth hormone, and pasireotide. We report two cases of IGF-2 mediated hypoglycemia. The first was managed surgically to good effect, highlighting the importance of a timely diagnosis to maximise the likelihood of a surgical cure. The second patient had unresectable disease and was managed medically, adding to a growing number of cases supporting the efficacy of glucocorticoids and recombinant growth hormone in NICTH.

Learning points

Recurrent fasting hypoglycemia in the setting of a malignancy should raise suspicion of non-islet cell tumour hypoglycemia (NICTH), which is typically mediated by IGF-2.

The initial workup for NICTH should include a serum glucose, C-peptide, insulin, insulin antibodies, beta-hydroxybutyrate, IGF-2, IGF-1, and sulphonylurea screen during a spontaneous or induced hypoglycemic episode.

An IGF-2/IGF-1 ratio above 10 is highly suggestive of IGF-2-mediated hypoglycemia if the IGF-2 level is normal or elevated. False positives may be seen with sepsis and cachexia as both IGF-2 and IGF-1 are subnormal in these cases. A low IGF binding protein 3 (IGFBP3), such as in renal failure, may also result in a falsely normal or low IGF-2/IGF-1 ratio.

Surgical resection of the associated tumour is curative in most NICTH cases.

When the tumour is unresectable, moderate-dose glucocorticoids, low-dose glucocorticoids in combination with recombinant growth hormone, and pasireotide are medical therapies with promising results in controlling NICTH.

Clay or other minerals are coated onto fibrous paper to improve print and optical properties. The minerals are fixed to the fibrous substrate with a binder, either latex or starch. The coated paper is dried during manufacture, and if the binder migrates during this drying, there can be a deterioration in properties. Not only are there manufacturing considerations as to the choice of binder, but also environmental ones with regard to factors such as the energy used in drying. This work reveals new perspectives on binder migration which have been gained by a variety of approaches. Firstly, a critique is presented of the experimental methods which have been used by other workers. Then a comprehensive series of experiments is described. For ease of study, and because any effects are likely to be exaggerated, most of the experiments were carried out on samples which were 1.4 mm thick, some two orders of magnitude thicker than commercial coatings. However, the results were also replicated in less extensive tests on samples of thickness 55 μm. The experiments show that under a very wide range of conditions, including different coating thicknesses and drying temperatures, no latex migration is observed. Migration of starch was observed, however, and caused an increase in starch concentration at the surface during drying. If the sample was covered during the experiments, the system relaxed back and the concentration enhancement was reduced. The relationship between the particle size of the latex and starch, and the extent to which these particles might percolate through the void structures, was investigated by the application of the “Pore-Cor” software to mercury intrusion experiments. Also presented are the results of a mathematical continuum model, which accurately describes the migration of starch binder in terms of only two parameters, namely the evaporation efficiency and the diffusion coefficient of starch.
Dynamics analysis of a nonlinear controlled predator–prey model with complex Poincaré map
Authors: Cheng Huidong , Zhang Xin , Zhang Tonghua , Fu Jingli
Published: March 2024

In this paper, we propose a class of predator–prey models with nonlinear state-dependent feedback control in the saturated state. The nonlinear state impulse control leads to a diversity of pulse and phase sets such that the Poincaré map built on the corresponding phase sets behaves like the single-peak function and multi-peak function with multiple discontinuities. We start our study by analyzing the exact pulse and phase sets of models under various cases generated by the dependent parameter space of nonlinear state feedback control, then construct the Poincaré map that is followed by investigating their monotonicity, continuity, concavity, and immobility properties. We also explore the existence, uniqueness, and sufficient conditions for the global stability of the order-1 periodic solutions of the systems. Numerical simulations are carried out to illustrate and reveal the biological significance of our theoretical findings.

Published: March 2024

BACKGROUND AND OBJECTIVES

Approximately half of youth suicides involve firearms. The promotion of safe firearm storage in the home through lethal means counseling reduces suicide risk. We aimed to increase the documentation of firearm access and storage among children presenting to the emergency department (ED) with suicidal ideation or self-injury to 80% within 13 months.

METHODS

We conducted a multidisciplinary quality improvement initiative to improve the documentation of firearm access and storage among children <18 years old seen in the ED for suicidal ideation or self-injury. The baseline period was February 2020 to September 2021, and interventions occurred through October 2022. Interventions included adding a templated phrase about firearm access to psychiatric social work consult notes and the subsequent modification of the note to include all firearm storage elements (ie, locked, unloaded, separate from ammunition). Statistical process control and run charts were generated monthly to monitor the documentation of firearm access and storage, which was measured through a review of keyword snippets extracted from note text.

RESULTS

We identified 2158 ED encounters for suicidal ideation or self-injury during the baseline and intervention periods. Documentation of firearm access increased from 37.8% to 81.6%, resulting in a centerline shift. Among families who endorsed firearm access, the documentation of firearm storage practices increased from 50.0% to 78.0%, resulting in a centerline shift.

CONCLUSIONS

The modification of note templates facilitated increased documentation of firearm access and storage practices for children with suicidal ideation in the ED. Future studies should assess whether improved documentation is associated with improved storage practices and reductions in firearm suicides after ED encounters.

La incorporación de biocarbono para mejorar los suelos agrícolas está ganando popularidad, pero hay poca información sobre las propiedades del biocarbono derivado de los restos de la cosecha de cacao. En la investigación se determinó varias características del biocarbono obtenido a través del proceso de pirólisis de la cáscara de las mazorcas de cacao. Los análisis realizados fueron: porcentajes de fibra lignocelulósica, análisis proximal, estructura microscópica y grupos funcional. También se realizó con el biocarbon un ensayo de adsorción con Cd+2 mediante un sistema de recirculación con agua, con el fin de obtener las isotermas de Langmuir y Freundlich. Los contenidos fibrosos abarcaban 56,2% celulosa, 27,07% lignina y 3,15% hemicelulosa. Con 8,15% de humedad y pH 9,86, se obtuvo un promedio de 35,58% de biocarbón. La forma de los poros fue irregular, se confirmó la presencia los grupos hidroxilo, carboxilo y carbonato. Los modelos de absorción indicaron una capacidad de adsorción máxima de 0,280 mL/g en Langmuir y una intensidad de absorción de Cd+2 de 0,06 en Freundlich. Si bien el biocarbón demostró propiedades adecuadas para suelos ácidos, su capacidad de adsorción resultó limitada en las condiciones evaluadas.

Angiogenesis is the process of formation of new blood vessels in tissues and organs, which occurs with the participation of many factors. Angiogenesis can be influenced by various factors, such as mechanical tissue stretching, hypoxia, infections, inflammation, and others. Understanding these mechanisms can be important for the development of new approaches to the treatment of various diseases associated with angiogenesis disorders. The process of angiogenesis plays an important role in various physiological and pathological conditions, such as wound healing, tissue regeneration, tumor development, and others. Regulation of angiogenesis can be used for the treatment of diseases associated with a lack of blood circulation. Knowledge about angiogenesis can also be useful for planning and conducting surgery, to increase the efficiency of the surgery, which can help significantly reduce the risk of complications, and avoid repeated interventions. Purpose - to search and analyze the recent publications to identify trends in the direction of influence on vascular growth. The search for publications was carried out in well-known global scientometric databases, the range of which spanned more than 10 years. Published results of many years of research, factors and methods of influence on angiogenesis were found and analyzed. To date, the questions of the impact on angiogenesis remain open, which calls for further research and study of new methods and improvement of existing ones, since knowledge about the mechanisms of angiogenesis can help to develop new methods of treatment and prevention of various diseases.

The achievements of contemporary medicine, application of advanced technologies and comprehensive therapeutic and diagnostic investigations are not limited to broadening the range of professional opportunities for pediatric surgeons but also require further rationalization of the axiological discourse of medical deontology. Purpose. The article aims at theoretical and methodological substantiation of the axiological principles of medical deontology in pediatric surgery. The theoretical and methodological foundation of the scientific research includes the theory of creative development and self-improvement of an individual, the theory of education and personal development in changing socio-cultural conditions, concepts of humanization of education, conceptual approaches to the general theory of activity and philosophical theories of values. The professional activities of medical workers in pediatric surgery inevitably include the process and result of a deontological dominant, manifested in the profound understanding by the medical experts of their professional and human duties, and in a high moral and ethical responsibility for the quality of their professional activities. Conclusions. Philosophy and axiology constitute the worldview and methodological basis of medical deontology, particularly in surgery. The genesis of knowledge about moral and ethical principles and the professional duty of a pediatric surgeon is presented in the form of a logical chain: philosophy - axiology - deontology - medical deontology - deontology in surgery - deontology in pediatric surgery. The process of forming the deontological competence of medical professionals in pediatric surgery will be successful if the organization of deontological training for future healthcare providers is based on principles of humanism, in compliance with the requirements of the social environment, and implemented in the educational process through a productive mechanism.

Internship training in surgery is carried out according to individual curricula developed on the basis of the internship training program. A comprehensive approach to solving topical issues of internship training will allow to raise the professional level of future doctors and surgeons. Purpose - to show the specifics of the training of interns of the 1st year of study in accordance with individual curricula and the program of training in an internship in surgery. 11 interns are completing the 1st year of training in the educational part of the surgical internship at the Department of Surgery of Odesa National Medical University. During the 1st year of internship in surgery, interns are trained in the educational part of the internship for 3 months (15.6 credits / 468 hours) from the following courses: Course 1. Organization of surgical services to the population. Course 3. Abdominal surgery. Course 7. Purulent surgical diseases. Course 8. Ambulatory surgery. Course 9. Thoracic surgery. Simulation training of surgical skills is an integral part of the surgical curriculum to acquire the necessary skills. The practical part of the internship takes 8 months (1248 hours). Acquired competencies / practical skills are reflected in the “Practice Diary”. The structure of the practical part of the internship determines the mastery level for each competency, practical skill, which is determined in the range from “A” to “C”: A: Has knowledge, describes. B: Assists. C: Performs under supervision. Conclusions. During the first year of training in a surgery internship, the intern’s activities must be carefully monitored. The level of independent practice of an intern surgeon of the 1st year of training is based on active involvement in providing assistance, providing formative feedback between clinical supervisors and supervisors.

Metabolic disorders caused by chronic hyperglycemia in the gastrointestinal tract of patients with type I diabetes mellitus (T1DM) not only affect natural course of this disease but also modify clinical course of concomitant abdominal purulent-inflammatory diseases in children due to changes of the internal intestinal wall. Purpose - to analyze pathomorphological and morphometric features of acute appendicitis in children with T1DM. Materials and methods. We carried out a pathomorphological and morphometric case-control study of the surgical specimens (appendices and fragments of the peritoneum). Two groups were created: the Group I (n=11) - patients with acute appendicitis, peritonitis and T1DM; the Group II (n=24) - patients with acute appendicitis, peritonitis but without T1DM. Statistical analysis was performed using software package STATISTICA v.10.0 (StatSoft, USA). Results. There were signs of diabetic angiopathy in the Group I and a significant number of inflammatory cells, represented by a large number of segmented nuclear leukocytes - 431±18.2 in 1 mm2, plasma cells - 146±11.13 in 1 mm2, lymphohistiocytic elements - 196±23,32 in 1 mm2. The density of the inflammatory cell infiltrate was 773±36.2 cells in 1 mm2. Morphometric features of the Group II are as follows, number of segmented nuclear leukocytes - 228±15,7 in 1 mm2, plasma cells - 112±10,41 in 1 mm2, lymphohistiocytic elements - 132±21,2 in 1 mm2. The density of the inflammatory cell infiltrate was 773±36.2 cells in 1 mm2. Conclusions. There is an increase in the density of the inflammatory cell infiltrate, the number of neutrophils, plasma cells, and lymphohistiocytic elements in samples of appendices and peritoneum in children with acute appendicitis and T1DM in comparison with the Group II (p˂0.001). Furthermore, those specimens feature presence of hyalinosis, thickening of the vascular wall and partial obliteration of small caliber vessels. In the Group II (patients without T1DM), the parietal and visceral peritoneum had a large number of inflammatory elements and presence of macrophage elements upon normal histological structure of the microcirculatory vessels. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of participating institution.

The problem of surgical treatment of perforation of gastroduodenal ulcers (GDU) remains relevant and difficult, despite the introduction of new schemes of anti-ulcer and eradication therapy. Algorithms of surgical approaches and tactics of surgical treatment of patients with perforated GDU in combination with other complications in various combinations have not been developed. Purpose - to improve the results of surgical treatment of GDU with associated complications. Materials and methods. The results of surgical treatment of patients with complicated GDU for the period from 2000 to 2022 are presented. In total, 353 (100%) patients with perforated GDU in combination with other complications (a combination of two or more complications) were operated on. There were 52 (14.7%) patients with gastric ulcer perforation, and 301 (85.3%) patients with duodenal perforation. There were 267 (75.6%) patients with a combination of two complications; with a combination of three complications in 78 (22.1%) patients; four - 8 (2.3%) patients. The combination of perforation with gastrointestinal bleeding was observed in 138 (39.1%) patients. Results. The vast majority of patients (267 (75.6%)) had a combination of two complications. The number of patients with a combination of three complications was 78 (22.1%). The number of patients with a combination of all complications was insignificant - 8 (2.3%) people. The implementation of the developed algorithm made it possible to reduce the number of postoperative complications and mortality from 12% to 6.5%. The highest rate of complications and mortality was observed among patients with a combination of multiple (three and four) complications who underwent gastric resection - 3 (33.3%) patients, and the lowest mortality rate was observed among patients who underwent organ-preserving operations - 6 (2.8%) patients. Conclusions. In patients with perforated GDU in combination with bleeding, the use of endoscopic hemostasis made it possible to stabilize the patient and better prepare him for surgical intervention, and reduce the number of postoperative complications and mortality rates by almost 2 times. The use of resection techniques was extremely limited and had the highest rate of complications and mortality. Implementation of the developed algorithm made it possible to optimize surgical tactics when combining perforation with other complications of GDU. The research was carried out in accordance with the principles of the Declaration of Helsinki. The research protocol was approved by the Local Ethics Committee of the institution mentioned in the work. Informed consent of the patients was obtained for the research.

Despite the achievements of modern pediatric surgery, to date there is no single comprehensive approach to the treatment and prevention of adhesive intestinal obstruction (AIO), both primary (prevention of adhesions formation after primary surgery) and secondary (prevention of recurrence). Purpose - to study the clinical effectiveness of treatment, primary and secondary prevention of postoperative intestinal adhesive obstruction in children. Materials and methods. An examination and analysis of medical records of 119 children aged 5 months to 17 years who were treated at the Pediatric Surgery Clinic of Ivano-Frankivsk National Medical University over the past 10 years for post-operative AIO was carried out. In 35 (29.41%) children a positive effect was achieved from conservative treatment. The remaining 84 (70.59%) children were operated on. Two groups of patients were formed: the comparison group - 38 (45.24%) children, who received traditional treatment, and the main group - 46 (54.76%) children, who were intraoperatively applied anti-adhesive gel to prevent recurrence of postoperative AIO. Results. It was established that postoperative AIO occurred in only 1 (1.19%) child after laparoscopic intervention, in the rest of the children primary surgical interventions were performed by an open method. In the comparative assessment of the postoperative course in two groups of patients, we drew attention to a more favorable course in the children of the main group, which was manifested by a faster recovery of peristalsis, a decrease in the duration of gastric stasis, a faster appearance of independent defecation, and a shorter period of inpatient treatment. When comparing the results of treatment between groups of patients, it was established that the frequency of recurrences of AIO in the main group of patients was 5.44 times lower than in children of the comparison group, and the frequency of relaparotomy for recurrent AIO was 7.28 times lower than in patients of comparison group. We did not observe complications associated with the use of anti-adhesive gel. We did not notice a significant difference in the results of treatment between patients who were treated with anti-adhesive gel of different composition (based on carboxymethylcellulose and sodium hyaluronate). Conclusions. The most effective method of primary prevention of postoperative adhesive intestinal obstruction is the use of laparoscopic primary surgical interventions. Intraoperative application of anti-adhesive gel is a highly effective and safe recurrence prevention method of adhesive intestinal obstruction in children. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.
