Системний цикл людські ресурси-знання-капітал для інновацій: поняття, основні складові та особливості
Authors: Нечаєва Ірина
Published: October 2024

У представленій роботі досліджено критичні аспекти інноваційного процесу, зокрема роль людського капіталу, знань та інвестицій у забезпеченні ефективного розвитку інновацій. Попри значні досягнення в цій галузі, наявні дослідження мають суттєві недоліки, оскільки лише людський капітал та обмін знаннями не гарантують успішного інноваційного результату. Ключовою умовою є залучення капіталу. Аналіз наукових джерел демонструє важливість інвестицій у процес інновацій, підкреслюючи їх значення для конкурентоспроможності та сталого економічного зростання. Зокрема, інвестиції в дослідження та розробки (R&D) є важливими для створення нових продуктів і послуг, а венчурний капітал сприяє фінансуванню інноваційних проєктів, незважаючи на високі ризики. Цифрові технології також відіграють значну роль у підвищенні ефективності бізнесу, скороченні витрат та підвищенні задоволеності клієнтів. Важливою є і державна підтримка інноваційної політики, що стимулює інвестиції та сприяє розвитку конкурентних ринків. Дослідження доводить необхідність системного підходу, де людські ресурси, знання та капітал взаємодіють і взаємопов'язані, забезпечуючи циклічний процес інновацій. Це включає мобілізацію і управління критичними ресурсами для підтримки безперервного інноваційного циклу. В роботі проведено порівняння концепції “інноваційної екосистеми” та “системного циклу людських ресурсів, знань та капіталу для інновацій”. Інноваційна екосистема включає взаємодію між різними організаціями та інститутами, що сприяють інноваціям, тоді як системний цикл фокусується на внутрішніх процесах і управлінні ресурсами в організаціях. Висновки дослідження наголошують на важливості обох підходів для розуміння та оптимізації інноваційних процесів.

Examining the School Climate Influence on Jamaican Secondary School Students: A Comprehensive Literature Review
Authors: Small Bartley Michele
Published: October 2024

This article synthesises the literature on the socioecological factors within the school climate - quality and character of school life (Cohen, 2009) influencing adolescents’ resilience. The review focuses on social relationships and the mechanisms used for teaching and learning practices. Resilience is a positive development outcome resulting from a triadic interactive process between the adolescent, the internal capacity, and the socioecological factors within the environment (Ungar, 2008). Changes imposed by COVID-19 on teaching and learning practices assumedly altered the school climate and are known to impact adolescents’ psychosocial well-being. Transforming the school climate at its minimum will require improving social relationships, communicating expectations, and creating a school environment where students will feel safe. Giving students autonomy through active and productive engagement in decisions that affect their developmental outcomes is critical for success. Expansion of this study requires applying a methodological approach that allows for students’ perspectives of the school climate, careful measurement of their resilience levels and lived experiences of students and other school personnel.

Published: October 2024

The growing animal welfare concerns regarding poultry production have led to the rearing of slow-growing meat type chickens also known as free-range chickens. In Zimbabwe these slow-growing chickens are gaining popularity as an alternative to the commercial broiler chickens owing to their preferred sensory attributes comparatively. Little is known regarding the quality of the meat versus that of the conventional broilers. We evaluated the physical characteristics and nutritional composition of meat from dual purpose slow-growing hybrids, Sasso C431 and TR51 in comparison with the commercial broiler breed Ross 308, under intensive feeding conditions. Birds were fed the standard commercial chicken feed produced by Hamara, a local chicken and chicken feed producing company. Birds were slaughtered on days 42, 56 and 70 of life where carcass and breast yield were measured. The pH, drip loss and cooking losses were determined for all carcasses. Proximate composition (dry matter, ash, protein, fat, carbohydrate) and mineral composition (iron, zinc and phosphorus) were determined for all the meat samples. The fast-growing broiler breed had a higher breast yield; than the slower-growing breeds, Sasso C431 and TR51 breeds (P<0.05). The highest cooking and drip loss were observed in the faster growing breed Ross 308 and the lowest ones for Sasso C431 and TR51 breeds (P<0.05). Shear texture values were higher in the Sasso C431 and TR51 than the Ross 308 breed (P<0.05). The Sasso C431 and TR51 breeds can produce more meat with a lower fat and a higher protein compared to the Ross breeds.

Authors: Jane Egbo Nwakaku , Chukwudi Ugoh Sylvester , Sunday Olisa Babafemi
Published: October 2024

This study investigated the efficacy of some fungicides activities on fungal seed borne pathogens of two commercial maize seeds (Sammaz 15 and Sammaz 52). A total of 2500 seeds were randomly picked for each variety to represent a working sample from the seed reference collections. Out of the 2500 seeds, 400 seeds were surface–sterilized with 10% sodium hypochlorite solution, cultured and examined microscopically for the presence of fungal pathogens. Molecular analysis confirmed that all isolated pathogens matched with the reference accession from NCBI molecular database. Seeds were treated with different dosages of fungicides viz Thiram and Metalaxy + Tebuconazole and incubated for 5 days. The effect of the various fungicides on the incidence of seed- borne fungi, effect on seed germination and interaction of the fungicide were evaluated and analyzed. Percentage occurrence of the fungal pathogens revealed that Sammaz 15 have F. solani (29.0%), A. flavus (20.3%), A. niger (19.0%) and Rhizpus stolanifera (15.0%). In Sammaz 52, A.niger (40.0%), A. flavus (19.7%) and F. solani (27.0%). It was observed that F. solani was predominant in sammaz 15 while A. niger was predominant in Sammaz 52. Thiram (45.88 mm) at all doses showed greater inhibitory effects on mycelia growth than Metalaxyl + Tebucanozole (24.25 mm). The correlation analysis performed  on the data set reveals that  there is a  negative significant  correlation between  zone of  inhibition  and percent  disease  incidence  (r = -0.99***), but the relationship was positive with number of non-infected seeds (r = 0.99***). This shows that increasing the zone of inhibition will increase the number of non-infected seeds and the normal seedling (germination percentage). Thiram fungicides observed to be more effective in reducing the disease incidence than Metalaxyl fungicides.

Published: October 2024

Ensuring food security by Indonesia's Golden Year in 2045 presents a formidable challenge, with advancements in agricultural technology anticipated to play a crucial role in attaining this goal. Rice is the major food crop in Indonesia, and its consumption is still considerably high, indicating that daily nutrient uptake relies on its grain. However, the current population of Indonesia demanding rice is 31.2 million tons and this number of populations will grow at the rate of 0.41 percent. The rice consumption of the Indonesian people is quite high, namely 114.6 kg per person per year. The rice harvest area in 2023 decreased by 2.45%, from 10.45 million hectares to 10.20 million hectares, resulting in rice production which also decreased from 31.54 million tons to 30.90 million tons. The average conversion of paddy fields to non-harvest areas in Indonesia reached 100,000 hectares per year. Meanwhile, the average ability to print rice fields is only 60,000 hectares a year. This means that there is a difference in the conversion of paddy fields of around 40,000 hectares per year. Therefore, the purpose of this study is to elucidate how agricultural technology can enhance rice production across different land types in Indonesia, thus supporting food security efforts. To achieve the objectives of this research, a systematic literature review method was used. The result of this study shows that the amalgamation of diverse technological advancements and innovative practices in rice cultivation holds immense promise in bolstering productivity, bolstering sustainability, and tackling nutritional deficiencies. Prospectively, the use of cutting-edge technology offers some insights that can be input for policy formulation, technological innovation, and community engagement strategies aimed at creating a safer, fairer, and more sustainable food future for Indonesia to achieve food security by 2045.

Published: October 2024

Optimizing agricultural crop production involves utilizing proper irrigation and fertilization techniques. A two-year experiment conducted in the Tselemty district during the off seasons of 2019 and 2020 aimed to assess the impact of varying irrigation levels and nitrogen fertilizer application rates on the growth, yield, and crop water productivity of pepper. The study included three irrigation levels (75%, 100%, and 125% of the required irrigation) and three nitrogen fertilizer application rates (75%, 100%, and 125% of the recommended amount). Analysis of the results using Gen-Stat software revealed that most pepper yield attributes were not significantly affected by the different irrigation and fertilizer levels. However, the marketable yield showed significant variation based on the combined application rates. The research indicates that, under ideal circumstances, the optimal approach for pepper growers is a combination of meeting 100% of the irrigation requirement and applying 100% of the recommended nitrogen fertilizer rate. Nevertheless, in scenarios where water resources are limited and fertilizer expenses are high, a reduced irrigation level of 75% of the requirement coupled with 75% of the recommended nitrogen fertilizer rate could be a viable alternative that does not lead to a substantial decrease in yield.

Published: October 2024

In our study, the biological activity of Hylocereus polyrhizus obtained from Türkiye was determined. Firstly, antimicrobial activity of methanol extracts obtained from H. polyrhizus against test microorganisms was determined by disc diffusion susceptibility assay, minimum inhibition concentration (MIC) and minimum fungicidal or bactericidal concentration (MFC or MBC) tests. Then, viable cell counting against Limosilactobacillus fermentum MA-7 using the macro-dilution method was used to determine the probiotic-promoting effect of the fruit extracts. Finally, the photo-protective activity of the extracts and extract-cream mixtures was obtained spectrophotometrically. The inhibition zone diameter of the peel extract against the test microorganisms is in the range of 9.60-12.37 mm and the fruit extract is in the range of 7.85-12.00 mm. MBC values ranged from 40 µg/µl to 80 µg/µl in peel extract and between 10 µg/µl and >80 µg/µl in the fruit extract. The inhibition zone diameters of the extracts against probiotics were determined as 6.10 -10.25 mm. As a result of the viable cell count, the viability rate of L. fermentum MA-7 increased as the fruit methanol extract concentration and time increased. The photoprotective activities of the peel and fruit extracts were determined as 13.17 and 12.26. It was determined that the extracts increased sun protection factor (SPF) value of the cream. The results indicated that H. polyrhizus extracts may have potential for use in the nutraceutical products, cosmetic and pharmaceutical industries.

Bioplastic technology is one of the efforts made to address the problem of plastic packaging which can pollute the environment. Environmentally friendly plates, bioplastic products made from tapioca, glycerol and sugar cane bagasse. This research aims to determine the effect of variations in the size of bagasse on tensile strength, elongation at break, water resistance and biodegradability of environmentally friendly plates and to obtain the best formulation of varying sizes of bagasse as raw material for making environmentally friendly plates. This research used a Completely Randomized Design (CRD) with one factor, namely variation in the size of the bagasse. The results of this research show that there is a real influence between tensile strength, water resistance and biodegradability, however, in the elongation test, variations in bagasse did not have a significant effect. Tensile strength values range from 20.00 N/mm2 to 47.72 N/mm2. The largest elongation value is 4.08%. The highest water resistance is at room temperature, namely 88.86% with a degree of curvature of 16⁰ and in water with a temperature of 60⁰C, namely 85.02% with a degree of curvature of 18.75⁰. Variations in the size of bagasse also affect the biodegradability of environmentally friendly plates which ranges from 11.77% to 14.65%. The best treatment is a sample with a variety of bagasse sizes of 60 mesh, because it has high strength compared to other samples.

Lightweight metal matrix composites made of aluminium are now essential in several fields, including aerospace and automotive. An important factor determining the quality and properties of the composite material is the ease or difficulty of evenly dispersing the reinforcement throughout the matrix. The goal of this research is to find out the impact of 40 and 90 µm varying- sized boron carbide (B4C) particles in A356 alloy composites. Using the liquid stir casting technique and K2TiF6 as the wetting flux, A356 alloy with 9 wt.% of B4C composites were prepared. SEM and EDS images were used to study the material’s microstructure. ASTM-approved methods were used to measure the material’s mechanical properties. Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) confirmed that B4C particles were evenly distributed throughout the A356 alloy. The addition of B4C reinforcement to the A356 alloy matrix increased the hardness, ultimate, yield, compression, and impact strength of composites with a reinforcement size of 40 μm. The hardness of A356 alloy was enhanced by 40.7% and 34.6%, respectively, when 9 wt. % of 40 and 90 μm B4C were added. Similarly, there was a 34% increase in ultimate strength and a 31% improvement in yield strength. Both cases showed a little decrease in the ductility of the composites. Scanning electron micrographs were used to examine the morphologies of tensile fractured surfaces.

This research paper presents an approach for predicting student academic success using Hidden Markov Models (HMMs). Leveraging a comprehensive dataset encompassing students’ demographics, academic performance, attendance records, and course engagement, the study employs an HMM framework to model levels of student academic success. Observable emissions derived from the data, such as grades and interaction patterns, are utilized to train the HMM and infer the most likely sequence of hidden states for new students. Evaluation of the proposed model demonstrates promising predictive accuracy. Through rigorous assessment using standard metrics including state prediction accuracy and state transition accuracy, the effectiveness of the HMM in capturing diverse student trajectories is demonstrated, underscoring the potential of HMMs as a powerful tool for understanding and predicting student outcomes, offering valuable insights for educational interventions and support systems.

This paper explores the application of artificial intelligence (AI) in education to improve teaching processes. Through the analysis of relevant literature, various aspects of the application of AI technologies in the educational sector are explored. It has been found that AI can provide a personalized academic experience and more efficient information retrieval; however, AI answers are perceived as often lacking in accuracy and correctness and should not be unquestioningly trusted. The research instrument was an online survey given to 105 university students with several types of questions to discover whether our students were familiar with the concept of AI tools. Through the analysis of the available literature and the student’s response, it is concluded that a viable option to improve the learning and teaching process is a balance between traditional teaching methods and the application of AI technologies, where AI could support teachers through dynamic and interactive lessons and provide additional resources tailored to individual student needs. At the same time, the need for careful development and use of AI technologies concerning ethical principles and continuous expert supervision is strongly emphasized, underlining the crucial role of educators, researchers, and policymakers in ensuring responsible AI use in education.

Investigation Of Dielectric Properties For SnO2-PVA/n-Si Schottky Barrier Diode
Authors: Bilkan Çiğdem
Published: October 2024

The dielectric properties of SnO2-PVA nanocomposite films were examined graphically using capacitance (C) and conductivity (G/w) data obtained over a wide frequency and voltage range at room temperature. For SnO2-PVA/n-Si, some dielectric parameters (dielectric constants (ε', ε'') and electrical modulus (real M' and imaginary M'' parts), loss tangent (tan δ) and ac electrical conductivity (σac) frequency and voltage dependence were calculated. As the frequency increased for each applied bias voltage, the ε', ε'' and tan δ values decreased, and it was observed that the changes in these parameters were more effective at low frequencies due to the additional loads on the interface states. While M' increases as the frequency increases due to the short-range mobility of charge carriers and has low values in the low-frequency region. The value of M'' decreases as the frequency increases due to the decrease in polarization and the density of interface states (Nss) effects. While the value of electrical conductivity is almost constant at low frequencies, it increases almost exponentially at high frequencies.

Published: October 2024

Interest in H2 energy, which is one of the alternative energy sources that can meet the energy needs of the increasing world population, is increasing day by day. However, dangerous properties of H2 gas such as high flammability and explosiveness require sensitive detection of this gas. For this purpose, intensive research is being carried out on the detection of H2 gas with high response values at low gas concentrations. In this study, the structural, morphological and H2 gas sensing characteristics of NiO thin film, which grown on quartz substrate by RF sputtering. XRD results of the produced film revealed that the NiO film has a polycrystalline cubic structure with (101), (012), (110) and (113) diffraction planes. The lattice constant of the film was obtained as 4.226 nm, which differed by 1.274% from the theoretical values presented in the literature. From the special scanning XPS spectrum of the Ni element, the presence of peaks corresponding to Ni+2, Ni+3 and NiOOH on the film surface was detected. SEM images revealed the existence of a homogeneous structure on the film surface consisting of structures with grain sizes of 10-20 nm. Current changes obtained at 100, 500 and 1000 ppm H2 concentrations at 300°C showed that the produced film was sensitive to H2 gas and the current value increased as the ppm value increased. For 1000 ppm H2, the response value was 11.49, the response and recovery times were 239 and 286 seconds, respectively. Gas sensor measurements have also shown that the NiO film produced may have p-type conductivity.

Published: October 2024

Background. Gastrointestinal stromal tumors localized in the duodenum are very rare and account for only 4–5%. They can be asymptomatic, while reaching large sizes and causing dangerous complications. Gastrointestinal stromal tumors of the duodenum are a special problem for diagnosis and treatment. Therefore, it is relevant to highlight the issue of their detection and treatment on the example of the presented clinical case.
Purpose – present a description of the literature and present a rare clinical case of gastrointestinal stromal tumor of the duodenum.
Material and methods. The patient, a 49-year-old woman, was diagnosed with a tumor of the abdominal cavity during a routine preventive ultrasound examination. The patient underwent a laboratory and instrumental examination, which included determination of blood and urine parameters, video esophagogastroduodenoscopy, contrast x-ray examination of the gastrointestinal tract, contrast-enhanced computer tomography and contrast-enhanced magnetic resonance imaging of the abdominal cavity.
Results. The patient underwent surgical resection of the tumor of the duodenum. During the immunohistochemical study, the tumor cells were positive for markers DOG-1, CD117. As a result, «Gastrointestinal stromal tumor of the wall of the duodenum of a low degree of malignancy pT2N0M0R0» was diagnosed. During the six-month follow-up of the patient, no data on tumor recurrence were found. The relatively rare frequency of gastrointestinal tumors of the duodenum leads to difficulties at the diagnostic stage. In this clinical case, the tumor was asymptomatic, was not visualized during video esophagogastroduodenoscopy and was suspected during ultrasound examination. This indicates the importance of preventive examinations. Oncological awareness of doctors is extremely important for early diagnosis of oncology.
Conclusion. Based on the analysis of the literature, the data on the epidemiology, clinical picture, methods of diagnosis and treatment of this rare pathology are displayed.
