Authors: Porter Jared M. , Velten Joei , Badami Rokhsareh , Nezakatolhossaini Maryam , Lotfinejad Maryam
Published: April 2024

Introduction.
The primary purpose of the present study was to investigate whether providing knowledge of results (KR) on more accurate trials enhanced motivation and self-confidence or whether providing KR on less accurate trials reduced those variables. We also investigated whether anxiety was affected by the provision of feedback.

Material and Methods.
Participants performed a volleyball serve over four days of practice under one of two conditions: After each block of six trials, one group received feedback on the three most accurate (MA) trials, whereas the other group received feedback on the three least accurate (LA) trials. One week following practice, participants performed a retention test without feedback. Participants also completed the intrinsic motivation inventory (IMI) and the Competitive State Anxiety Inventory-2 (CSAI2).

Results.
Results indicated that the MA group had more effective learning as well as higher motivation and self-confidence scores than the LA group. Additionally, the MA group had lower scores on cognitive and somatic anxiety compared to the LA group. The MA group had higher motivation and self-confidence scores and lower anxiety compared to the values reported on the pre-test. Conversely, the LA group had lower motivation and self-confidence scores relative to the pre-test values, and tended to have increased cognitive and somatic anxiety following practice.

Conclusions.
The results of this study demonstrate that providing augmented feedback about more accurate trials facilitates motor learning and increases motivation and self-confidence whilst lowering levels of somatic anxiety.
What Links Retail to Modernity? The Future of Retail - Romanian Case Study A combined Analysis of Consumer Perceptions and AI Insights
Authors: Strătilă (Irimia) Andreea
Published: April 2024

This study examines the link between retail and modernity and bring as case study the Romanian perception of the future of the store. The research combines insights from secondary data consumer perception study with the potential applications of AI research. We explore convergences and divergences between AI-generated perspectives and actual consumer beliefs and expectations, focusing on technology integration, sustainability, and experiential retail. While both AI and the the consumer perception study highlight the importance of technology, the research reveals specific consumer concerns like affordability and cultural nuances that AI might not fully capture. The combined analysis offers valuable insights into Romanian consumer preferences and identifies potential future trends in the retail landscape. By acknowledging limitations like the scope of AI analysis and data source restrictions, we emphasize the need for further research integrating AI with diverse research methods for a comprehensive understanding of the future of retail in Romania.

Zwischen 1900 und 1936 formierte sich im damaligen Völkerkundemuseum Basel eine Sammlung europäischer Ethnologie: Dinge des Alltags, des Glaubens und Dinge der Festlichkeiten kamen zusammen – zuerst aus der Schweiz, dann immer mehr auch aus anderen Teilen Europas. Welche Prozesse haben dazu geführt, dass rund 12000 Dinge aus ihrem einstigen Kontext herausgelöst und in eine museale Sammlung überführt wurden?
Die Autorin versteht die Sammlung als Kristallisationspunkt unterschiedlicher Faktoren. Dazu gehören Zeitgeist, Weltgeschehen und gesellschaftliche Netzwerke ebenso wie Geldnot, Platzmangel und Schädlingsbefall. Sie haben im Zusammenspiel miteinander dazu geführt, dass die Dinge zusammenkamen. Das Buch geht einerseits den relevanten Faktoren nach und erzählt andererseits den Weg von 21 Einzeldingen.

Authors: Giang Dang Minh Huong , Hieu Nguyen Duc , Hue Chu Thi , Mai Pham Thi Ngoc , Huong Nguyen Thi Anh , Anh Hoang Quoc
Published: April 2024

Polycyclic aromatic hydrocarbons (PAHs)  and their derivatives are a diverse group of organic pollutants, which are relatively persistent and toxic. Simultaneous determination of unsubstituted PAHs and methylated PAHs (Me-PAHs) is necessary to provide comprehensive insights into contamination levels and sources of these pollutants. In this study, we collected surface sediment samples in Vietnamese central coast to analyze 7 PAHs and 12 Me-PAHs. The sediment samples were extracted by using a focused ultrasonic processor with acetone/hexane (1:1) mixture and toluene. The extract was purified by column chromatography technique with activated silica gel and dichloromethane/hexane (1:3) as elution solvent. PAHs and Me-PAHs were determined by a gas chromatography/mass spectrometry (GC/MS) system operated in electron impact ionization (EI) and selected ion monitoring mode (SIM). Concentrations of total 7 PAHs and 12 Me-PAHs ranged from 30 to 246 (average 92) nanograms per gram sediment (ng/g). These levels were comparable to or lower than those measured in Vietnamese river sediments and marine sediments from some other countries in the world. The accumulation profiles of PAHs and Me-PAHs indicated that their emissions are likely associated with mixed pyrogenic and petrogenic sources. Our results have provided preliminary information about the pollution degree and accumulation characteristics of these substances in Vietnamese marine environments. Additional comprehensive studies should be performed to characterize contamination characterisrics, emission sources, and ecological risks of PAHs and their derivatives in this country.
Chińskie tłumaczenia Biblii
Authors:   Uniwersytet Opolski, Wydział Teologiczny, Klejnowski-Różycki Dariusz
Published: April 2024

Translating the Bible into Chinese has been a challenge for all Christian denominations for centuries. Protestants were the pioneers. Although there is evidence that there were translations of biblical texts as early as the 7th century, related to the mission of Alopen and the Church of the East, no translation texts have survived to our times. In 1822, the first complete Bible was published in Chinese. It was a translation by Hovhannes Ghazarian and Joshua Marshman. In parallel, independently, Robert Morrison and William Milne worked on translations of the Bible, and their Bible was published in 1823. In 1863, the Delegates’ Version was published, followed by the Chinese Union Version in 1919, and the Revised Chinese Union Version in 2010. Catholics paid less attention to Bible translations than Protestants. They created works directly serving the pastoral ministry. However, the translation of the Bible (Protestant and Catholic) was significantly influenced by the work of Jean Basset in the 17th century. Gabriele Allegra was of crucial importance, who led to the finalization of the complete Catholic Bible translation in 1968. Another contemporary translation is the Pastoral Bible from 1998 as an initiative Catholic Pastoral Edition. Father Alberto Santiago Rossa headed the Chinese translation work. This is the translation also used by Catholics. Orthodox Christians also undertook translation work, but they concerned only the New Testament. Among the most distinguished translators were: Archimandrite Gury Karpov, Flavian Grodecky, Innokenty Figurovsky. Each generation must re-read the Bible and translate it into the language of its time. It is a continuous work showing that the Bible is alive in the hearts, minds and language of all nations.

22 invertebrate taxons of zoobenthos were found over the entire study period in the Zimnyaya Zolotitsa River at the Lomonosov diamond deposit. The number of sampling points (stations) for monitoring period is 6. The average number of taxons per station for the entire monitoring period is 11, ranging from 3 to 16. Almost annually, larvae of chironomidae were found at all stations in samples; the frequency of them for all stations over the entire monitoring period was 94%. In addition, the mayfly larvae (89%), diptera larvae (85%), оligochaeta (82%) and hydrachna (78%) were the most common. The average value of the Shannon index as a whole on the studied part of the Zimnyaya Zolotitsa river system for the period 2000–2021 amounted to 1.87, varying from 0.76 (the Svetly Creek, 2016) up to 2.9 (the Svetlaya River). The Margalef species wealth index as a whole on the studied part of the Zimnyaya Zolotitsa River was 0.85. The Pielu equalization index averaged 0.58, indicating the presence of dominant taxons in samples. The number of invertebrates on the studied section of the Zimnyaya Zolotitsa River over the years of monitoring varied from 110 to 28375 spec/m2, averaging 5369 spec/m2. The biomass of invertebrates on the studied part of the Zimnyaya Zolotitsa River over the years ranged from 0.026 to 29.060 g/m2, on average – 4.015 g/m2. Despite the lack of negative impact on the river ecosystem, one of the dominant groups in the zoobenthos is оligochaeta, the proportion of which varied from 4.4% at 148 km from the mouth of the Zimnyaya Zolotitsa River up to 24.1% at 152 km. Taking into account the relatively high proportion of oligochetes in benthic samples, an oligochete index was used to assess water quality in the Zimnyaya Zolotitsa River. In general, the Zimnyaya Zolotitsa river system is estimated as pure – the average оligochaeta index for all sampling points for the entire monitoring period was 8%. One-time increases in the оligochaeta index to maximum values suggest a slight contamination of the river based on the index gradation. These increases are likely related to natural processes in the river system, as evidenced by high оligochaeta index values at the upper sampling points (169 km) located outside the deposit area.

The paper considers the impact of ground sulphur (S 0 ) used as a chemical ameliorant for alkali-saline soils, as well as of sulphur with mineral and organic fertilizers, on species diversity and abundance of soil phototrophic microorganisms – algae and cyanobacteria. The research was carried out in laboratory conditions through the example of alkali soil. The alkali type is automorphic, its subtype is brown semiarid. Application of ground sulphur, as well as sulphur with mineral and organic fertilizer additives to alkali-saline soil caused considerable change in its chemical and physical-chemical properties: рН decrease, and increase in conductivity and phosphorus, potassium, magnesium, and calcium content in soil extract. Soluble carbonates and hydrocarbonates content decreased. Changes in soil properties and chemical composition effected species composition and abundance of soil algocyanoflora. 16 species, including Cyanobacteria – 10, Bacillariophyta – 4, Chlorophyta – 2, were found in the control soil. 25 species of soil microphototrophs, such as Cyanobacteria – 14, Chlorophyta – 4, Bacillariophyta – 7, were found in the soil of experiment variants. Algocyanoflora species composition of control and experiment variants remains mostly the same (64%). Application of mineral and organic additives caused growth of algocyanoflora species diversity in soil. Sulphur application contributed to microphototrophs cells increasing in number. The highest species diversity of microphototrophs found in the variant with sulfur and a complex of mineral and organic fertilizers.

A study on the quality characteristics of pan bread added with Suaeda asparagoides power
Authors:   The Table and Food Coordinate Society of Korea, Hong Geum-Ju , Kim Myung-Hee
Published: April 2024

This study examined the quality characteristics of bread enriched with Suaeda asparagoides powder, including antioxidative activity, at concentrations of 0%, 1%, 2%, 3%, and 4%. Analysis of Suaeda asparagoides powder revealed a moisture content of 5.34%, ash content of 21.03%, protein content of 32.08%, fat content of 5.12%, and a DPPH-free radical scavenging ability of 90.24%. The moisture content of the bread decreased with an increase in Suaeda asparagoides powder, although the difference was not significant. Conversely, the pH of the bread increased with higher concentrations of Suaeda asparagoides powder. The addition of Suaeda asparagoides powder led to an increase in weight, while the volume, cost, and baking loss rate decreased with higher concentrations. Hardness increased with greater amounts of Suaeda asparagoides powder, whereas springiness remained unchanged between the control group and the group with added Suaeda asparagoides powder. Sensory evaluation revealed that bread with 2% Suaeda asparagoides powder received the highest scores for color, flavor, taste, and overall preference. These results suggest that 2% is the optimal concentration of Suaeda asparagoides powder for enhancing the sensory quality and functional benefits of the bread.

According to observation data in the summer period 2016-2021. The interannual variability of weather conditions, water temperature and chlorophyll (Chl) content in the Kuibyshev Reservoir was considered. Regular observations were carried out at the outlet section of the reservoir (Zhigulevsky hydroelectric complex) under conditions of complete mixing of water masses. It has been established that the main factors influencing the process of mass development of cyanobacteria (MDC) are thermal regime and weather conditions. With increasing water temperature, the interval and degree of favorable activity of cyanobacteria increases. Over a 6-year period, the average interval was 44 days, the largest was 72 days, and the smallest was 11 days. The degree of favorability varied widely: from low (23 °С ˃ t ˃ 22 °С) to extreme high (t ˃ 26 °С). The most favorable years for the MRC process were 2016 and 2021, when the Chl content during the summer period was 6.2 and 7.2 μg/dm3, respectively. The least favorable years were 2017 and 2019, when the Chl content during the summer period was 0.6 and 1.4 μg/dm3, respectively. Seasonally, the temperature optimum was observed annually in July. The Chl content in July 2021 was 12.6 μg/dm3, and in the cold July 2017 – 0.7 μg/dm3. Significant variability of the MRC process is due to synoptic cyclicity and changing weather conditions. The established influence of thermal regime and weather conditions on the content of chlorophyll suggests that in conditions of global warming, the process of mass development of cyanobacteria is expected to intensify, which will negatively affect the ecological state and water quality of the Kuibyshev Reservoir.

Objective: To study the association of X-ray repair cross-complementing group 1 (XRCC1) gene polymorphisms with increased laryngeal cancer risk. Methods: A total of 120 individuals, comprising 60 patients with laryngeal squamous cell carcinoma (LSCC), and 60 healthy volunteers participated were selected. Blood samples were taken and analyzed, and 4 XRCC1 polymorphisms (rs145135970, rs1799780, rs25489, and rs72484243) were genotyped. Results: Gender, age, body mass index (BMI), and smoking habits were shown to be the high-risk factors for LSCC. Genotype and allele distributions for the 4 polymorphisms differed significantly between both groups (P < 0.05). Furthermore, carriers with the rs72484243GTGT- allele exhibited an increased risk of LSCC relative to those who had the rs145135970 GTGTGTGTGTGTGT- allele, the rs1799780 G-A allele, or the rs25489 C-T allele, as determined by binary logistic regression analysis (OR = 2.74, 95% CI: 1.27–5.91, P = 0.01), after accounting for possible co-factors like sex, age, BMI, drinking and smoking behavior, and special diet requirements. In addition, a TA haplotype and a GTGTGTGTGTGTGTTG haplotype were linked to LSCC in Chinese populations in a haploid association study of 4 SNP loci in the XRCC1 gene (P = 0.05 OR = 1.36, 95% CI = 1.1228–1.6406). Conclusion: Genetic polymorphisms of the XRCC1 gene at the rs72484243 site were correlated with an elevated risk of LSCC among the Xinjiang population.

Recently, they have been integrated into automated process lines for manufacturing automobile interior components. Consequently, with the advancement of water-jet robot processing technology, a dedicated fixture is required to support the product shape for processing complex-shaped automobile interiors. The existing water-jet processing fixtures were produced through a wet lay-up process using glass fiber to reduce manufacturing costs; however, recently, water-jet fixtures employed in automated lines have experienced deformation over prolonged usage, resulting in shape-processing errors and an increased the defect rate. Therefore, this study explores the use of carbon fiber and the VARTM vacuum bagging process to enhance the quality of water-jet dedicated fixtures, refine the manufacturing process, alleviate shape strain, and bolster the structural integrity of the fixtures compared to the conventional wet lay-up method typically employed for composite fixtures. A study was conducted on.

In this investigation, we developed the hardware for a low-latency low-density parity check (LDPC) decoder and validated its error-correction performance. The LDPC code was chosen as the error-correction code conforming to the international portable Internet standard IEEE 802.16e. The LL-LDPC code, implemented in this study, efficiently minimizes the number of coded calculations through the utilization of a type of Structured-LDPC code defined by the physical layer description in IEEE 802.16e. The low-delay LDPC decoder employs a parallel decoding method to mitigate the decoding delay associated with repetitive decoding. Comprising four SISO modules based on four coding repetitions in the coder, the low-delay LDPC decoder significantly reduces delay times. The four SISO modules operate in parallel, enabling simultaneous decoding and thereby decreasing the delay time by 1/4 compared to alternative approaches.

Higher order thinking skills are one of the competencies developed in learning, especially in mathematics. One of the effective learning models to improve higher order thinking skills is Problem-Based Learning (PBL). In this study, a meta-analysis method was used, which involved analyzing various articles that had been collected. Search procedures through Google Scholar and Garuda Portal and found 99 articles that discuss the effect of PBL implementation in Indonesia on students' higher order thinking skills. Of these 99 articles, only 11 articles met the inclusion criteria and were then analyzed using the meta-analysis method. This meta-analysis method provides results in the form of a combined effect size that describes the extent of the influence of PBL implementation on students' higher order thinking skills. Based on the interpretation of the combined effect size, it can be concluded that overall, the application of PBL has a moderate effect on students' higher order thinking skills. In other words, PBL has a positive impact in improving students' ability to think critically, analytically, creatively, and think reflectively. In addition, this study also considered study characteristics, such as education level and year of study. The statistical analysis showed the effect of PBL implementation in improving students' ability to think critically, analytically, creatively, and reflectively.

The effect of the initial size of alumina particles on the density, microstructure, hardness, and fracture toughness of ceramics obtained by conventional and spark plasma sintering (SPS) has been studied. We studied ceramics obtained from commercial Al2O3 powders with an initial particle size of 40 – 50 nm, 0.2 mm, and 1 mm, and domestic fine powders with an initial particle size of 0.2 – 3 mm, and Al2O3 + 0.25 vol. % MgO and Al2O3 + 10 vol. % ZrO2. It is shown that the density of alumina ceramics nonmonotonically depends on the initial size of Al2O3 powder particles. It has been established that an increase in the grain size leads to a nonmonotonic change in the hardness of alumina ceramics. It has been established that the addition of 0.25 vol. % MgO accelerates the sintering of alumina. The addition of 10 vol. % ZrO2 makes it possible to provide an optimal combination of hardness and fracture toughness. It is shown that fine-grained ceramics obtained by the SPS method have a higher hardness. It has been suggested that SPS of submicron alumina powders with an amorphous layer on the surface, additionally stabilized by zirconia particles, is promising for further increasing the hardness of alumina ceramics.

An analysis of the crystal structure and composition of Co – Ni – Fe films was carried out and the influence of the deposition rate on the conversion of a weak magnetic field into a magnetic induction dB/dH was established. The presence of oxygen on the surface of the films indicates the porosity of the structure of the Co – Ni – Fe films, which is confirmed by the roughness of the morphology. Electrochemical deposition from a chloride electrolyte showed the possibility of controlling the magnetic properties of films while improving the deposition method. Chloride electrolyte with filtration, additives of boric acid, saccharin and hydrochloric acid at a ratio of concentrations CCo:CNi:CFe = 1: 1: 1 with a temperature of 70 °C provides reproducible electrochemical deposition of Co – Ni – Fe films with low mechanical stresses, with a uniform structure and with a high gain of a weak magnetic field in magnetic induction.

An original technique for modifying graphene oxide with iodine has been developed. It is shown that when graphene oxide is treated with iodine, oxygen-containing groups are removed from the surface of graphene planes, which improves the electrically conductive properties of the material. The change in the structure and electrical conductivity of the modified graphene oxide, depending on the concentration of iodine, has been studied. According to Raman spectroscopy data, it can be seen that the composition of the modified materials includes molecular complexes of iodine I3– and I5–. Changes in the structure of the crystal lattice of iodine-modified graphene oxide films were studied using X-ray phase analysis. According to IR spectroscopy, the effect of iodination on the change in the qualitative composition of functional groups in the material was analyzed. The specific electrical conductivity of graphene oxide as a result of modification increases from 9.6·10–10 S/cm for the original material to 3.3·10–7 S/cm for the material treated with an isopropanol solution containing 1 wt. % I2 relatively dry graphene oxide. The additionally modified films were heat treated at 80 °C for 2 hours. The resulting changes in the structure of the material are analyzed and an increase in electrical conductivity by one or two orders of magnitude is shown.

The method of self-propagating high-temperature synthesis (SHS), combined with pressing, for the first time obtained a metal-intermetallic material based on gorenje products of the layered system (Ti – Al – Mg)/Ti. Exothermic synthesis from elementary powders was carried out at a pressure of 10 MPa, and pressing of the hot synthesis product at a pressure of 250 MPa. The paper demonstrates that as a result of SHS-pressing, an integral connection of the “intermetallic/metal” layers is formed. The main features of microstructure formation, phase composition and strength properties of transition zones at the boundary between reacting SHS compositions Ti – Al – Mg and Ti-substrate are investigated. The thickness of the transition zone between the layers was at least 15 µm. The results of energy dispersion analysis (EDA) showed that magnesium Mg in the synthesized alloy is mainly in the intergranular layers, in the form of a small amount of Ti – Al – Mg compound, which indicates incomplete reaction diffusion between Ti – Al and Al – Mg layers. The microhardness of Ti – Al grains in the synthesized alloy has an average value of 5820 MPa, and the matrix based on Al – Mg is 3980 MPa. The hydrostatic density is 3.3 g/cm3, with a porosity of less than 13 %. As a result, the method of SHS-pressing turned out to reduce the porosity of the resulting Ti – Al – Mg-based alloy by 3 times.

New technologies of microelectronics are emerging to reduce the size of devices and combine them into more compact ultra-low power systems. Betavoltaic power sources (BVPSs) can serve as power generators of such order. BVPSs consist of a combination of betavoltaic cells (BVCs) based on long-lived radioisotopes of beta radiation and semiconductor converters (SCs). One of the key tasks for increasing the power of BVC is the selection of SCs that can efficiently convert the energy of beta particles into electricity. Currently, semiconductor structures with a developed surface and a high band gap are considered to be perspective SCs. In present work, arrays of titanium dioxide nanopores (TiO2 NPs) synthesized by common electrochemical anodization was chosen as a SCs. These SCs were part of BVCs based on nickel-63 with an activity of ~ 10 Ci/g. TiO2 NPs with an amorphous structure in the composition of BVC demonstrated low electrical parameters. To increase them, we modified TiO2 NPs by the hydrothermal method in a solution of Sr(OH)2 with a concentration of 0.05 mol/l at various times. These experiments were carried out in order to convert TiO2 (anatase) into structure-like SrTiO3. We found that the electrical parameters of the SCs increased with the duration of the modification time. The best result was obtained in case of 3 h modification — the BVC generated a short circuit current 2,9 nA, open circuit voltage 0,8 V and had a maximum power 0,8 nW at 0,45 – 0,5 V. The obtained electrical parameters in combination with the miniature dimensions of the BVCs open up the potential possibility of creating a BVPS with an increased power density.
