The rates of the CO2 electrochemical reduction were determined on porous cathodes formed by electrochemical dealloying of CuZn under different regimes of selective anodic dezincification of brass. It was established that the formation of a porous surface proceeds in two following stages: 1) the dissolution of Zn from the CuZn mainly along the grain boundaries with the formation of submicron crevices between them, and 2) electrochemical dezincification of brass grains and formation of nanopores. The zinc content in the nanoporous copper surface is less than 1%. It was proved that anodically dezincified brass porous cathodes demonstrate a significantly higher CO2 reduction current on their surface than smooth copper and brass surfaces. For instance, in aqueous solutions, at an electrode potential of –1.5 V, the value of cathode current density on porous Cu cathodes is between 5 to 9 mAcm–2, while it is only 2.5 and 1.5 mAcm–2 on smooth Cu and CuZn cathodes, respectively. A similar trend is observed in an acetonitrile environment, where the current density of the CO2 electroreduction at the electrode potential of –3.0 V is 22 to 27 mAcm–2, 15 mAcm–2, and 18 mAcm–2 on porous cathodes, Cu cathode, and CuZn cathode, respectively. As the pore size decreases from submicron to submicron-nanosized, there is a tendency for an increase in cathodic currents by approximately 80% and 25% in aqueous and in acetonitrile solutions, respectively. Additionally, CO2 recovery on porous cathodes remains stable during long-term electrolysis at an electrode potential below –1.5 V.

To date, reactor-grade zircon is produced on an industrial scale using metallothermic and electrochemical methods. Electrolytic production of reactor-purity zirconium in a sealed electrolyzer is more cost-effective than metallothermic production, as it does not require iodide refining and the use of reducing metals (Na, Mg, and Ca). Despite the importance of this production, its features are not fully described in the literature. This study presents the results of industrial tests of the electrolysis process in a sealed electrolyzer with a current load of 10 kA from the molten electrolyte KCl–KF–K2ZrF6. Based on the achieved technological indicators, the current efficiencies of the main cathode and anode reactions were determined and the factors influencing them were evaluated. We analyzed the composition of nutrient salts and the mechanism of accumulation of potassium fluoride in the electrolyte, an increase in which concentration leads to an anode-destroying effect. We considered possible mechanisms of the electrochemical formation of freons and compiled material balances for all starting substances and reaction products. The change in the electrolyte density during electrolysis was calculated, which allowed justifying the volume of its daily drainage. Fine carbon and zirconium powder formed in the electrolyte due to the interaction with potassium metal are not separated and are removed for chemical redistribution, which reduces the productivity of the electrolysis process.

Derivatives of 1,3,4-thiadiazole are very important for medical chemistry and pharmacy as potential drug substances. In this work, we carried out molecular docking studies of amidoalkyl derivatives of 1,3,4-thiadiazole: N-(2,2,2-trichloro-1-((5-aryl-1,3,4-thiadiazol-2-yl)amino)ethyl)carboxamides and N-(2,2,2-trichloro-1-((5-(arylamino)-1,3,4-thiadiazol-2-yl)amino)ethyl)carboxamides with dihydrofolate reductase (DHFR). The AutoDock Vina program based on the PyRx 0.8 platform was used for docking. Before docking, the enzyme structure (PDB ID: 1DLS) was prepared using the Chimera 1.14 program, and the structures of potential inhibitors and reference preparations were optimized by the PM3 method in the ArgusLab 4.0.1 program. According to the results of molecular docking, the analyzed compounds effectively interact with the active site of DHFR. It is shown that the introduction of an NH group between the 1,3,4-thiadiazole and aromatic rings leads to stronger binding of ligands to DHFR. Based on the results of molecular docking, the following hit compounds were selected: 4-methyl-N-(2,2,2-trichloro-1-((5-(phenylamino)-1,3,4-thiadiazol-2-yl)amino)ethyl)benzamide and 4-methyl-N-(2,2,2-trichloro-1-((5-(p-tolylamino)-1,3,4-thiadiazol-2-yl)amino)ethyl)benzamide, which are superior to the reference compounds according to the strength of the formed complex.

The high density of silicon carbide ceramics is a prerequisite for obtaining materials with high strength. A promising technology for preparation of such materials at relatively low temperatures is the use of glass crystal bonds. The paper presents the results of studies on ceramic materials based on silicon carbide using glass in the pseudoternary system MgO–Al2O3–SiO2 as a glass binder. The composition of the glass corresponds to a ternary eutectic with a temperature of 13650C, which is located at the boundary of the primary crystallization fields, where one of the phases is cordierite. It has been determined that it is necessary to mechanically activate the components of the raw material mixture to obtain densely sintered ceramics. In this case, the most rational ratio between SiC filler and glass binder, which provides the maximum mechanical compressive strength (up to 700 MPa), is 60:40. It has been established that the crystallization of the glass binder plays a decisive role in determining the formation temperature of dense silicon carbide materials. The compaction occurs due to the movement of dispersed silicon carbide particles in the softened glass melt under the influence of thermal vibrations. The subsequent process of fine-dispersed crystallization of the glass binder during cooling during firing provides strengthening of the structure of the synthesized materials. The proposed integrated approach to the intensification of the sintering process is promising for obtaining durable silicon carbide ceramics with low synthesis temperatures (up to 16000C). A sufficiently high strength of the experimental ceramics will ensure its competitiveness with respect to traditional materials, including those used as wear and impact resistant.

Authors:   Ho Chi Minh City Open University, Đoàn Bảo Sơn
Published: October 2023

Green human resource management is critical to enhancing the ability of the companies’ green innovation, but this link is rarely explored in the literature. There are inadequate studies investigating the green innovation when firms implement organizational policies, which may play a critical role in this process. Adapted from Natural-Resource-Based View (NRBV) theory, this study develops the model of the relationship between green human resource management (GHM) and green innovation (GI) in manufacturing small and medium-sized enterprises (SMEs) with the mediation role of green intellectual capital (GIC), which includes 3 dimensions: green human capital (GHC), green structural capital (GSC) and green relational capital (GRC). The author tested the research hypotheses using a structural equation modeling (SEM) with survey data from 393 top manager of manufacturing SMEs in Ho Chi Minh city. Structured questionnaires were designed to collect data and snowball sampling technique was used. The empirical findings demonstrate that GHM positively impacts on GHC, GSC, GRC and GI. At the same time, GI is driven by the three dimensions of GIC. The research results suggest that SMEs’ top managers should have appropriate strategies to promote GI through GHM and GIC.
Public investment project audit: Vietnam state audit case study
Authors:   Faculty of Accounting and Auditin, Industrial University of Ho Chi Minh City, Vietnam, Đặng Anh Tuấn
Published: October 2023

Public investment project audits aim to confirm the completed settlement report and point out shortcomings and limitations in managing and implementing public investment projects to help the audited entity exercise accountability and improve management efficiency. The study aims to explore the priority strategy of the State Auditor's approach to audit investment projects. The study used document analysis, interviews, and data analysis of 362 public investment projects from 2016-2020. Research results indicate that state auditors pursue a results-oriented audit approach instead of confirming financial information of investment projects. The primary motivation of the auditors is to detect deviations in investment projects instead of ensuring the overall information of investment projects to provide more reliable information to users. This motivation mainly depends on the characteristics of the investment project, the size of the investment project, and the level of interest of the owner and the user of the audit report. In addition, the research results provide a more scientific basis to help users of investment project audit reports understand whether the purpose of the audit report is to provide a degree of confidence in the information or to contribute to increased accountability.

This study was conducted to determine the impact of foreign direct investment on economic growth in Vietnam. The dataset used in this study was collected from the Statistical Yearbook of the General Statistics Office of Vietnam (GSO, 2014, 2017, 2019). Data is taken from 63 provinces/cities in Vietnam in the period from 2010 to 2019 to examine the impact of FDI on growth in the last 10 years. The study uses quantitative research methods to assess the impact of factors on economic growth. Research results show that the variable FDI has a positive impact on economic growth in the short and long run. In the three economic sectors considered, FDI has a positive impact on the state sector and the foreign invested sector in the short and long term. In the non-state sector, FDI only has a positive effect in the short term, but no long-term effect is found in this sector. Besides, the export variable and the 1-year lagged variable of the dependent variable have the effect of increasing the economic growth, especially export is the factor that has the strongest influence on growth. Lower inflation will cause economic growth to increase. In addition, the human capital variable does not affect economic growth in general, but when considering each sector human capital has both positive and negative effects on economic growth.

Stock price manipulation is a widespread issue globally, but it becomes particularly acute in emerging markets due to severe information asymmetry. This harmful practice has significant adverse effects on society, the economy, and investors, driven primarily by the pursuit of economic gain. Stocks of small companies with limited liquidity and transparency are particularly vulnerable to manipulation. Although institutional investors may engage in stock price manipulation at times, they also have the potential to enhance transparency and reduce such activities in the market. To identify instances of manipulation, economists have developed advanced models utilizing machine learning, artificial neural networks, support vector machines, and decision trees. In light of previous studies, the author proposes several solutions to curb stock price manipulation in Vietnam. These include raising awareness among investors, providing professional ethics training for employees in the financial industry and government, enhancing market transparency and integration, strengthening supervision, and imposing strict sanctions on individuals and organizations violating securities regulations.

Published: October 2023

The article is based on secondary data collected from sectors and agencies in the period 2006-2021, and based on the socioeconomic context and growth characteristics of Vietnam to evaluate the comprehensive growth situation of the country. Research results show that Vietnam has achieved remarkable comprehensive growth since its joining the WTO. Specifically, through indicators such as GDP scale, GDP per capita increasing day by day, increasing access to basic infrastructure facilities and services, more opportunities for people to socialize to ensure close equality with economic opportunities through education, health care, health care, stable jobs with increasing wages, people's living standards are increasingly improved through increased income levels and access to basic services such as electricity and clean water. In addition, gender equality and social security work are increasingly being actively promoted by the Government and society. However, besides the already achieved results, comprehensive growth in Vietnam still has certain limitations, in particular gender inequality, income inequality, persisting underemployment, unsustainable poverty reduction work, high income disparity among population groups and between regions, there is still a shortage of jobs and limited resources to implement social security. Therefore, people are not really happy and fair.

Purpose: This study aims to investigate the impact of neuromuscular exercises (NE) and local-indigenous games (LIG) on the static and dynamic balance of obese children. Methods: Thirty obese children were randomly assigned to NE (n=15, mean age 10.47±2.1 years, body mass index (BMI) 29.15±3.01 kg/m2) or LIG (n=15, mean age 10.67±1.52 years, body mass index (BMI) 29.45±3.41 kg/m2) groups. Both groups underwent 12 training sessions, during which dynamic and static balance were measured with the Biodex device before and after training. Analysis of covariance (ANCOVA) and independent t-test were used to compare balance indices between the two groups. Results: No significant differences were observed in static anterior-posterior balance between NE (0.82±0.10) and LIG (0.68±0.09). Similarly, no significant differences were found in static lateral-medial balance (NE: 0.82±0.10; LIG: 0.68±0.09) (P>0.05). Moreover, the dynamic anterior-posterior balance did not differ significantly between NE (0.79±0.08) and LIG (0.97±0.26) as well as the dynamic lateral-medial balance did not differ significantly (NE: 0.74±0.10; LIG: 0.93±0.15) (P>0.05). Conclusion: This study suggests that both NE and LIG are effective in improving balance indices in obese children. However, no significant differences were observed between the two interventions.

Refractory Axillary Web Syndrome Successfully Treated with Steroid Injections: A Case Report
Authors: Munayco Maldonado Gloria , Adepoju Omotinuwe
Published: October 2023

Background: Axillary Web Syndrome (AWS) manifests after breast cancer surgery as 1mm wide, singular, or multiple cords that can extend from the ipsilateral axilla to the antecubital fossa and further into the forearm and wrist. These cords can be painful and cause diminished range of motion. Even though there is no current standard treatment for AWS, physical therapy is recommended as the first approach in management. In refractory cases, no management has been proposed. 
Case Presentation: We present a case of a 59-year-old female with right-sided breast pain and a palpable cord, refractory to one year of physical therapy, which began at the inframammary fold up towards the lumpectomy scar and further towards the axilla. Cord developed post-lumpectomy and post-radiation for a right-sided stage I invasive ductal carcinoma with negative sentinel lymph node biopsy. Based on the refractory nature of the cord, the patient underwent three treatments of steroid injections which made the cord less palpable and improved the pain. Due to persistent diminished range of motion and tenderness, the patient underwent a percutaneous needle cord disruption procedure with a last round of corticosteroid injection to prevent adherence of the cord pieces. At a 7-month follow up post-procedure, the breast cord was no longer present, and range of motion had been restored.
Conclusion: We found that percutaneous cord disruption with concurrent steroid injections can be an effective treatment for AWS refractory to physical therapy.

Jenis penelitian merupakan penelitian deskriptif kuantitatif. Data menggunakan data sekunder berupa data runtun waktu (time series) yaitu Laporan Keuangan Pemerintah Daerah Kabupaten Trenggalek periode tahun 2017-2021 yang diperoleh dengan menggunakan teknik dokumentasi. Metode analisis data yang digunakan adalah analisis proporsi, statistik deskriptif - Cosstab dan analisis rasio keuangan.. Hasil penelitian ini menunjukkan bahwa selama periode 5 (lima) tahun 2017-2021 hanya memberikan kontribusi selama tahun 2017-2020 sedangkan tahun 2021 presentase konstribusi PAD dan Dau berada dibawah presentase kontribusi rata-rata. Penelitian ini tidak menemukan adanya Flypaper Effec pada pemerintah kabupaten Trenggalek. Analisis Kinerja keuangan Kabupaten Trenggalek dalam kategori masih belum optimal, meskipun dalam pengelolaan Pendapatan Asli Daerah sudah efektif dan efisien, akan tetapi tingkat kemandirian daerah masih rendah. Hal dibuktikan dengan lebih besarnya bantuan dana dari pusat dan provinsi dibandingkan dengan pendapatan asli daerah Kabupaten Trenggalek sendiri. Penggunaan dana juga masih belum berimbang karena sebagian besar dana digunakan untuk belanja operasi daripada belanja modal.
ARTIFICIAL INTELLIGENCE AS A METHODOLOGICAL INNOVATION IN THE TRAINING OF FUTURE DESIGNERS: MIDJOURNEY TOOLS

Published: October 2023

Applications of artificial intelligence are used in almost all spheres of human activity. Their use in the educational process at all levels of education is no exception. The article discusses the possibility of using a new generation of artificial intelligence Midjourney tools in the process of training future designers. A review of 2022 releases for creating complex, abstract or photorealistic images Stable Diffusion, DALL-E 2 and Midjourney. The analysis showed that Midjourney is most suitable for using artificial intelligence tools as a methodological innovation in training. The presence of an extended instruction on the formation of a prompt for the generation of an image stimulates non-standard new ways of thinking and allows you to expand the imagination of future design specialists. Midjourney developers recommend structuring the prompt by Subject, Medium, Environment, Lighting, Color, Mood, Composition. You can also use images from the Internet or add your own images. Any subscriber gets access to the gallery of Midjourney members. A survey of art students was conducted regarding the formation of a description of the proposed images. The result of image generation according to the students’ description using the Midjourney tool is given. The analysis of the answers confirms our assumptions about the need to form fundamental knowledge of the principle of operation of the image generation application; insufficient knowledge in visual arts as such; low ability to integrate knowledge of, one might say, opposite fields - art and exact sciences (mathematics, artificial intelligence, etc.); the lack of skills in formulating a description of images through the expression of the main categories of visual art through the linguistic means of language, whether in English or in the mother tongue. Such a situation prompts the selection of methods and means for developing the ability to carry out a qualitative verbal description of images and the surrounding reality in order to popularize the possibility of using artificial intelligence technologies in the process of training future designers.
Effects of hydroxyapatite-coated porous titanium scaffolds functionalized by exosomes on the regeneration and repair of irregular bone

Published: October 2023

As a traditional bone implant material, titanium (Ti) and its alloys have the disadvantages of lack of biological activity and susceptibility to stress shielding effect. Adipose stem cells (ADSCs) and exosomes were combined with the scaffold material in the current work to effectively create a hydroxyapatite (HA) coated porous titanium alloy scaffold that can load ADSCs and release exosomes over time. The composite made up for the drawbacks of traditional titanium alloy materials with higher mechanical characteristics and a quicker rate of osseointegration. Exosomes (Exos) are capable of promoting the development of ADSCs in porous titanium alloy scaffolds with HA coating, based on experimental findings from in vitro and in vivo research. Additionally, compared to pure Ti implants, the HA scaffolds loaded with adipose stem cell exosomes demonstrated improved bone regeneration capability and bone integration ability. It offers a theoretical foundation for the combined use of stem cell treatment and bone tissue engineering, as well as a design concept for the creation and use of novel clinical bone defect repair materials.

Late balloon valvuloplasty can be used to treat under-expansion-related transcatheter heart valve (THV) dysfunction. Whether this can be performed following redo-THV implantation is unknown. Herein, we report a case of a 72-year-old male presenting with symptomatic gradient elevation following redo mitral valve-in-valve implantation. The patient was successfully treated with late balloon valvuloplasty with gradient improvement. In conclusion, late valvuloplasty is effective even with several layers of valves. However, larger studies are required to clarify the role of this approach further.
Soil extracellular enzyme activity reflects the change of nitrogen to phosphorus limitation of microorganisms during vegetation restoration in semi-arid sandy land of northern China

Soil extracellular enzyme activity (EEA) and enzyme stoichiometry are indicators of soil nutrient availability and microbial substrate limitation. However, the patterns in soil enzyme activities and stoichiometry, and their key drivers remain unclear during vegetation restoration in degraded sandy land. Here, soil ecosystems at five restoration stages of degraded sandy land were selected for investigation and we quantified the microbial nutrient limitation using EEA stoichiometry. The average C:N:P ratio for the nutrient-acquisition enzymes was 1:0.88:0.86, which differed from the global ratio of 1:1:1, indicating stronger microbial C limitation than N or P limitation. With vegetation restoration, the enzyme N:P ratio decreased, but the angle term used in vector analysis increased, indicating that the restored grassland transitioned from N-restricted (angle < 45°) to P-restricted (angle > 45°). Plant C inputs increased the soil nutrient content and significantly decreased the microbial C and N limitation but increased P limitation due to nutrient competition between plants and soil microorganisms. Decreased soil water levels caused by vegetation transpiration may have shifted the microbial limitation from N to P. The decreased fungi:bacteria ratio strengthened the microbial C and N or P limitations. On the basis of these findings, as measures to alleviate the associated nutrient limitations, we would recommend supplementation with phosphorus in the potential and slight stages of rocky desertification and the supplementary application of nitrogen in the moderate and severe stages during the restoration of degraded sandy ecosystems.
