Authors: Wang Yuanshuo A. , Ranti Daniel , Bieber Christine , Galsky Matthew , Bhardwaj Nina , Sfakianos John P. , Horowitz Amir
Published: June 2023

BACKGROUND:

For decades, immunotherapies have been integral for the treatment and management of bladder cancer, with immune checkpoint inhibitors (ICIs) transforming patient care in recent years. However, response rates are poor to T cell-targeted ICIs such as programmed cell death protein 1 (PD-1) and programmed cell death-ligand 1 (PD-L1) blocking antibodies, framing a critical need for complementary immunotherapies. Promising strategies involve harnessing the activation potential of natural killer (NK) cells. They quickly exert their antitumor activity via signaling through germline-encoded activating receptors and are rapidly sensitized to new tissue microenvironments via their regulation by polymorphic HLA class I, KIR and NKG2A receptors.

OBJECTIVE:

In this review, we examined the roles of currently available NK-targeted antitumor treatment strategies such as engineered viral vectors, small-molecule IMiDs, NK agonist antibodies, interleukins, and chimeric antigen receptor (CAR) NK cells, and their potential for improving the efficacy of immunotherapy in the treatment of bladder cancer.

METHODS:

Through review of current literature, we summarized our knowledge of NK cells in solid tumors and hematologic malignancies as their roles pertain to novel immunotherapies already being applied to the treatment of bladder cancer or that offer rationale for considering as potential novel immunotherapeutic strategies.

RESULTS:

NK cells play a critical role in shaping the tumor microenvironment (TME) that can be exploited to improve T cell-targeted immunotherapies.

CONCLUSIONS:

Emerging evidence suggests that NK cells are a prime target for improving antitumor functions in immunotherapies for the treatment of bladder cancer. Further research into profiling NK cells in settings of immunotherapies for bladder cancer could help identify patients who might maximally benefit from NK cell-targeted immunotherapies and the various approaches for exploiting their antitumor properties.
Disability and surveillance: Disability justice as a framework for educational technology
Authors: Pucciarelli Alexandra , May Emma
Published: June 2023

The increased accessibility of technology is often employed as rationale for data extraction and surveillance. This paper examines critical perspectives on surveillance and educational technologies from Library and Information Science (LIS) literature, as well as those from disability studies that concern technology development more broadly. This research aims to understand how a disability justice framework can interrogate both the overall expansion of surveillance technologies and justifications for increased surveillance that argue that data extraction and analytics lead to increased accessibility for disabled users. As an activist approach toward disability advocacy that underscores the connections between white supremacy, sexism and colonialism as central to ableism, disability justice recognizes surveillance technologies as embedded in systems of power that disproportionately harm people of color, immigrants, transgender people, and gender nonconforming people. Using a disability justice framework, this paper argues against the expansion of surveillance technologies – especially in the name of increasing accessibility.
Conceptual modeling of Big Data extraction phase
Authors: Mallek Hana , Ghozzi Faiza , Gargouri Faiez
Published: June 2023

As the amount of information exceeds the management and storage capacity of traditional data management systems, several domains need to take into account this growth of data, in particular the decision-making domain known as Business Intelligence (BI). Since the accumulation and reuse of these massive data stands for a gold mine for businesses, several insights that are useful and essential for effective decision making have to be provided. However, it is obvious that there are several problems and challenges for the BI systems, especially at the level of the ETL (Extraction-Transformation-Loading) as an integration system. These processes are responsible for the selection, filtering and restructuring of data sources in order to obtain relevant decisions. In this research paper, our central focus is especially upon the adaptation of the extraction phase inspired from the first step of MapReduce paradigm in order to prepare the massive data to the transformation phase. Subsequently, we provide a conceptual model of the extraction phase which is composed of a conversion operation that guarantees obtaining NoSQL structure suitable for Big Data storage, and a vertical partitioning operation for presenting the storage mode before submitting data to the second ETL phase. Finally, we implement through Talend for Big Data our new component which helps the designer extract data from semi-structured data.

Published: June 2023

Background:

Depending on the therapy approach and disease background, the heterogeneity of muscular tissues complicates the development of targeted gene therapy, where either expression in all muscle types or restriction to only one muscle type is warranted. Muscle specificity can be achieved using promotors mediating tissue specific and sustained physiological expression in the desired muscle types but limited activity in non-targeted tissue. Several muscle specific promotors have been described, but direct comparisons between them are lacking.

Objective:

Here we present a direct comparison of muscle specific Desmin-, MHCK7, microRNA206- and Calpain3 promotor.

Methods:

To directly compare these muscle specific promotors we utilized transfection of reporter plasmids using an in vitro model based on electrical pulse stimulation (EPS) to provoke sarcomere formation in 2D cell culture for quantification of promotor activities in far differentiated mouse and human myotubes.

Results:

We found that Desmin- and MHCK7 promotors showed stronger reporter gene expression levels in proliferating and differentiated myogenic cell lines than miR206 and CAPN3 promotor. However, Desmin and MHCK7 promotor promoted gene expression also cardiac cells whereas miR206 and CAPN3 promotor expression was restricted to skeletal muscle.

Conclusions:

Our results provides direct comparison of muscle specific promotors with regard to expression strengths and specificity as this is important feature to avoid undesired transgene expression in non-target muscle cells for a desired therapy approach.

Authors: Tebaldi Letizia , Reverberi Davide , Romagnoli Giovanni , Bottani Eleonora , Rizzi Antonio
Published: June 2023

The well-known Radio Frequency Identification (RFID) technology is now evolving its applications: indeed, at the industrial level, it was firstly conceived at the pallet/case level for enhancing productivity and accuracy of logistics processes, while at present the focus is shifting towards item-level tagging applications for also managing in-store processes, including the selling experience. Due to a more technological customer, to the spread of e-commerce and the need of omnichannel sales availability, also Fast-Moving Consumer Goods (FMCG) are subject to an evolution of the way of selling, enabled by an item-level RFID tagging. Since these technologies are connected to the fourth industrial revolution, this novelty is referred to as Retail 4.0, which is still an uncommon term among the scientific community. For this reason, this paper makes an attempt to define the state-of-the-art of research and industrial projects on this topic, and it represents the first study investigating the Retail 4.0 from a practical side, closing the scientific gap regarding this issue. Eleven documents and fourteen projects focusing on item-level RFID tagging of FMCGs are examined and categorized according to a pre-existing use cases framework, and the enabled scenarios under a Retail 4.0 perspective are identified and defined. Inventory and Life-Cycle Management related use cases turned out to be the most investigated (7 scientific documents and 12 projects), while the User Experience was only considered at the industrial level (12 projects). From both sides, the Product Integrity was not perceived as relevant (2 articles and 6 projects); similarly, scarce attention was paid to the sustainability functionality of packaging with a total of 1 scientific paper and 5 projects.

Authors: Li Zhongwei , Wang Di , Hu Jiashou , Zhang Guowei , Sun Jinfeng
Published: June 2023

BACKGROUND: Juxta-papillary duodenal diverticula (JPDD) are common but are usually asymptomatic, and they are often diagnosed by coincidence. OBJECTIVE: To analyse the anatomy and classification of JPDD and its relationship with biliary and pancreatic disorders, and to explore the diagnostic value of multi-slice spiral computed tomography (MSCT) in patients with JPDD. METHODS: The imaging data of patients with JPDD, which was obtained via abdominal computed tomography examination and confirmed via gastroscopy and/or upper gastrointestinal barium enema, in our hospital from 1 January 2019 to 31 December 2020 were retrospectively analysed. All patients were scanned using MSCT, and the imaging findings, classification and grading were analysed. RESULTS: A total of 119 duodenal diverticula were detected in 96 patients, including 73 single diverticula and 23 multiple diverticula. The imaging findings were mainly cystic lesions of the inner wall of the duodenum protruding to the outside of the cavity. The thin layer showed a narrow neck connected with the duodenal cavity, and the shape and size of the diverticula were different: 67 central-type cases and 29 peripheral-type cases. There were 50 cases of type I, 33 cases of type II, 19 cases of type III and six cases of type IV. Furthermore, there were seven small, 87 medium and 14 large diverticula. The differences in the location and size of the JPDD in MSCT grading were statistically significant (P< 0.05). CONCLUSION: The MSCT method has an important diagnostic value for the classification of JPDD, and MSCT images are helpful in the clinical evaluation of patients with JPDD and the selection of treatment options.

Published: June 2023

BACKGROUND: Undesirable effects of tooth bleaching can alter the biomechanical properties of enamel. OBJECTIVE: To determine the influence of strontium fluorophosphate bioactive glass (Sr-FPG) on color, microhardness and surface roughness of enamel bleached with 35% hydrogen peroxide. METHODS: The labial enamel of 36 extracted intact human anterior teeth were divided into 3 groups (n= 12), group 1 (HP): bleaching with 35% hydrogen peroxide only, group 2 (Sr-HP): bleaching with Sr-FPG incorporated 35% hydrogen peroxide and group 3 (HP-SrFPG): bleaching with 35% hydrogen peroxide followed by remineralization with Sr-FPG. Four consecutive eight-minute applications of the bleaching gel were done twice in all the groups. Color change (ΔE), microhardness and surface roughness were evaluated at baseline, post-bleaching and post-remineralization using spectrophotometer, Vickers hardness tester and profilometric analysis respectively. RESULTS: The mean ΔE among the groups was statistically similar (p> 0.05). Bleaching with HP significantly reduced microhardness (p< 0.05), whereas bleaching with Sr-HP and HP-SrFPG did not (p> 0.05). Post-bleaching microhardness in Sr-HP was significantly higher than HP-SrFPG (p< 0.05). An increased surface roughness was seen in Sr-HP bleached samples (p< 0.05). CONCLUSION: The addition of Sr-FPG to hydrogen peroxide significantly improved enamel microhardness than its use post-bleaching. An increase in surface roughness was seen post-bleaching with HP and Sr-HP.

Increasing the efficiency of trenchless laying machines using vibrating knives
Authors: Suponyev Vladimir , Ragulin Vitaliy , Oleksyn Volodymyr
Published: June 2023

Modern requirements for the laying of underground communications consist of a combination of high construction rates with low energy consumption. The highest rate of laying linear objects is ensured by knife-type cable and pipe-layers, which are designed for their trenchless burial - this is when a narrow slot is cut in the soil, through which a cable or pipeline is launched. A feature of this process is the need to use large traction forces, which are determined by the resistance forces of the soil when cutting it. Accordingly, the cutting resistance of the soil depends on the dimensions of the width and depth of the gap and the physical and mechanical properties of the soil. Finding ways to reduce forces for deep cutting of soils is an important problem.

One of the ways to improve the efficiency of trenchless laying machines is to equip them with vibrating knives. It is known that when the knife oscillates in the vertical direction, it leads, depending on the soil and the speed of movement, to a 30…60% decrease in traction resistance. But the use of more complex vibration movements of the knives allows reducing the traction resistance during deep cutting of soils by 70…90%. It is well-known that various designs of mechanical drive are used to implement the process of vibration of knives. These are complex devices that, together with the entire machine, require calculations. Therefore, studying the forced vibration of the knives of pipe deepeners is an urgent task, which is aimed at reducing the energy consumption of the process of soil deep cutting and improving the overall performance of knife machines for trenchless laying of underground utilities.

To achieve the goal, the paper considered possible variants of the vibration oscillation of the knives and provided calculation dependencies for determining the resistance of soil cutting by active knives; also the dependence for determining the maximum average drive power of a centralized unbalanced vibrator was given. At the same time, the dimensions of the gap obtained, the physical and mechanical properties of the soil and the technical characteristics of the vibrator were taken into account.The obtained recommendations can be used when designing trenchless laying machines using vibrating knives.
Problem of plane strain state of two-layer body in dynamic elastic-plastic formulation (Part III)
Authors: Bogdanov Vladislav
Published: June 2023

Composites materials are artificially created materials that consist of two or more components that differ in composition and are separated by a pronounced boundary. The development of modern composite materials is associated with the discovery of high-strength whiskers, with the study and use of aluminides and high-strength alloys. At present, various composite materials have been developed and used: fibrous; reinforced with whiskers and continuous crystals and fibres of refractory compounds and elements; dispersion-hardened materials; layered materials; alloys with directional crystallization of eutectic structures; alloys with intermetallic hardening. There are many technologies for producing composites: imbibition of reinforcing fibres with matrix (base) material; cold pressing of components followed by sintering; sediment of the matrix by plasma spraying on the hardener, followed by compression; batch diffusion welding of multilayer tapes of components; joint rolling of reinforcing elements with a matrix, and etc. The use of composites makes it possible to reduce the weight of aircraft, cars, ships, increase the efficiency of engines, and create new constructions with high performance and reliability. The development of composites with high impact resistance is an important direction in the industry. The strength characteristics of a layered composite material are decisive under shear loads, loading of the composite in directions other than the orientation of the layers, and cyclic loading. In this paper, we study the non-stationary interaction of an absolutely rigid body on a two-layer reinforced composite material. The action of the striker is replaced by a non-stationary vertical even distributed load, which changes according to a linear function, in the area of initial contact, which is assumed to be unchanged over time. In contrast to the previous articles (Parts I and II), in this papers there is an investigation of the strain-stress state, the fields of the Odquist parameter and normal stresses depending on the material of the first (upper) layer.
Problem of plane stress state of two-layer body in dynamic elastic-plastic formulation
Authors: Bogdanov Vladislav
Published: June 2023

Composite materials are widely used in industry and everyday life. Many different methods are used to calculate and develop composite materials. Many methods of calculation and design of such materials are successfully used. In this article, for the design of composite and reinforced materials, a technique for solving dynamic contact problems in more precise an elastic-plastic mathematical formulation is used. To consider the physical nonlinearity of the deformation process, the method of successive approximations is used, which makes it possible to reduce the nonlinear problem to a solution of the sequences of linear problems. The problem of a plane stress state (PStS) of a beam made from the composite reinforced double-layered material is being solved in dynamic elastic-plastic mathematical model. The reinforced or armed material consists of two layers: the upper (first) thin layer of solid steel and the lower (second) main layer of glass. This composite base is rigidly attached to an absolutely hard half-space. Rigid adhesion of the layers to each other is assumed. Glass is a very strong and very fragile material at the same time. The fragility of glass is due to the fact that there are many microcracks on the surface, and when a load is applied to the glass surface, these microcracks begin to grow and lead to the destruction of glass products. If we glue or immobilize the tops of microcracks on the surface, we will get a strong reinforced armed material that will be lighter, stronger and not subject to degradation of material properties such as aging, corrosion and creep. The impact process was modelled as a non-stationary plane stress state problem with an even distributed load in the contact area, which changes according to a linear law. The fields of the Odquist parameter and normal stresses were studied and compared to corresponding results of plane strain (PSS) problem with the same material of layers, same their thickness and size of the contact area. The upper reinforcing layer of metal or steel can be applied to the glass surface so that metal or steel atoms penetrate deeply, fill microcracks and bind their tops. The top layer can be quite thin.

У статті подано результати порівняльного емпіричного дослідження, присвяче- ного виявленню відмінностей та особливостей сприйняття керівниками закладів загальної се- редньої освіти того, наскільки трудним для них є здійснення об’єктивної оцінки різноманітних характеристик і результатів перебігу освітніх і управлінських процесів як передумови успішно- го впровадження у діяльність закладу освіти внутрішньої системи забезпечення якості освіти. Дослідження проводилося методом анкетування. Внутрішня узгодженість запитань анкети, визначалась за допомогою α-критерію Кронбаха і склала 0,848. Було проаналізовано відповіді 199 керівників залежно від їх посадового статусу (директора або заступника директора). Результати статистичного аналізу підтвердили на рівні r = 0,05 наявність відмінностей між різними категоріями керівників закладів освіти (директорами і заступниками директорів) у ставленні до ступеня трудності дотримання ними об’єктивності в оцінюванні. Виявлено, що директорам шкіл в процесі ранжування властиво надавати у цілому більш високі оцін- ки власним відчуттям трудності дотримання об’єктивності при оцінюванні, ніж заступникам директорів. Величина ефекту відмінності склала у цілому d = 0,49, що відповідає приблиз- но середній величині відмінності результатів ранжування оцінок. Найвища величина ефекту (d = 1,13007) виявлена у сприйнятті очільниками закладів освіти ступеня трудності об’єктив- ного оцінювання параметрів аналітико-оцінювальної діяльності, найнижча (d = 0,06748) – параметрів самооцінювання керівниками власної компетентності та результативності профе- сійної діяльності. Обґрунтовано та за допомогою факторного аналізу підтверджено, що вияв- лені відмінності в оцінках керівниками закладів загальної середньої освіти сприйняття ступеня трудності оцінювання складових і характеристик освітніх та управлінських процесів можуть бути зумовлені специфікою професійної діяльності та відмінностями у посадових обов’язках цих категорій керівників.
ДОСЛІДНИЦЬКА ДІЯЛЬНІСТЬ СТУДЕНТІВ ПЕДАГОГІЧНОГО УНІВЕРСИТЕТУ ЯК ЗАСІБ ЇХНЬОГО ПРОФЕСІЙНОГО СТАНОВЛЕННЯ
Authors: КУДЛА Марія
Published: June 2023

У статті здійснено обґрунтування дослідницької діяльності студентів педагогічного університету як засобу їхнього професійного становлення. Сучасний етап розвитку вищої освіти вимагає перегляду методологічних, теоретичних та технологічних підходів до підготовки фахівця у педагогічних закладах вищої освіти. У зв’язку з цим перед педагогічною наукою та системою підготовки педагогічних кадрів постає завдання не лише формування педагога, який знає свій предмет, а й розвитку його професійних якостей, умінь аналізувати педагогічний процес, використовуючи прийоми та способи розумової діяльності через організацію самостійної роботи, володіти сучасними технологіями. У свою чергу педагогічний університет має вирішувати завдання професійної підготовки майбутнього педагога, вчити студента планувати свої дії з позиції дослідницького підходу, формувати особистість майбутнього педагога-дослідника. Дослідницька робота студентів сприяє формуванню навичок поглибленої самостійної роботи, розвитку наукового мислення, творчих здібностей, готує їх до безперервної освіти, орієнтує на ефективну самоосвіту, дозволяє проєктувати свою майбутню педагогічну діяльність. Теоретико-методологічний аналіз проблеми дозволив виявити та обґрунтувати умови, що сприяють розвитку дослідницьких вмінь майбутніх фахівців. До них належать: організаційно-педагогічні (оптимізація навчального процесу, інтеграція предметних дисциплін, створення творчої лабораторії та «креативного поля» для студентів та викладачів педагогічного університету) та психолого-педагогічні (діагностика рівня готовності до педагогічної діяльності, створення «перспективних ліній», психолого-педагогічна підтримка студента; забезпечення діалогічної взаємодії суб’єктів освітнього процесу на різних рівнях). Професійне становлення майбутнього фахівця є більш ефективним при застосуванні засобів дослідницької діяльності, якщо: метою професійної підготовки майбутнього фахівця є становлення особистості, здатної до самореалізації та саморозвитку власних творчих можливостей; реалізується цілісна система дослідницької діяльності студентів; упровадження поетапного професійного становлення майбутнього фахівця через дослідницьку діяльність, засновану на потребі самовираження та самореалізації особистості студента.
«СУСПІЛЬСТВО ВЕДУТЬ ВПЕРЕД НЕ ВИКОНАВЦІ, А ТВОРЦІ»: ЮЛО ВООГЛАЙД ПРО ОСВІЧЕНІСТЬ, ЯКІСТЬ ОСВІТИ ТА ПОВАГУ ДО ПЕДАГОГА

Осмислення можливостей та потенціалу освіти як індикатора та каталізатора суспільних змін актуалізує проблему пошуку нових світоглядно-теоретичних, методологічних засад її розвитку й модернізації. Безумовно, без якісної освіти майбутнє важко збудувати, оскільки вона йде в авангарді суспільних змін й задає тон суспільним змінам. Стан освіти є показником якості життя суспільства й людини зокрема. У цьому зв’язку актуалізується питання, осмислення, аналізу й можливості використання у практиках модернізації української освіти продуктивних напрацювань зарубіжних дослідників. Естонський науковець та освітянин Юло Вооглайд презентує своє бачення розвитку суспільства й відповідно освіти як рушія суспільного життя. Він переконує, що освіта є лише середовищем для розвитку й навчання людини. Освітній заклад – це лише оазис розвитку дитини, а освіта – ресурс. Її цінність саме у тому, щоб підготувати дітей до самостійного життя, а не оцінити їх. Людина отримує нові знання, уміння й досвід, розвиває світ духовності тощо упродовж усього життя. Вчителем у цьому процесі є саме життя, люди, ситуації й досвід. Засадничим завданням педагога є формування прагнення до пізнання, мотивація людини до розуміння світу та його осмислення, розкриття творчого потенціалу людини. Знання не мають цінності без їх розуміння та практичного застосування, тому важливим індикатором освіченості є досвід людини. Це те, що залишається на все життя. Інноваційні зміни в освітньому середовищі є доцільними тоді, коли ця система ще добре функціонує, але вже відчутні перші ознаки її кризовості. Йдеться про те, що інновації це не стільки порятунок системи від системної кризи, а неодмінний атрибут й ресурс її розвитку й функціонування. Життєві практики людини слугують освітнім середовищем, яке формує потреби до набуття нового досвіду й знаннєвого ресурсу, постійного його перегляду та є середовищем, де вона постійно навчається. Людина навчається скрізь, її знання й досвід формуються у практиках життя. Результатом цього процесу є рівень освіченості людини. Освіченість як здатність людини до самостійних рішень, уміння мислити, комунікувати, розуміти – це уміння сучасної епохи, а ще бути творцем свого життя.

Ukrainian pop song: development trends
Authors: Ovsyannikova Natalia
Published: June 2023

The purpose of the article is to determine the peculiarities of the formation and development of the Ukrainian pop song. Methodology. In achieving this goal, the following research methods were applied: comparison, systematization, analysis, and generalization of the problem studied.  The scientific novelty of the research lies in highlighting the main trends in the development of the modern Ukrainian pop song. Conclusions. Analysis of modern scientific literature devoted to the problem of the development of Ukrainian pop songs has shown an insufficient amount of systemic research in the field of national culture and art history.  As for the modern Ukrainian song stage, it is not reflected in scientific research, although it is popular now. It has been proven that in Ukraine over the past few years, quite favorable conditions have been created for the development of young performers, and the Ukrainian pop song takes leading places in the European musical space. The article does not exhaust all issues related to Ukrainian songwriting. Further research on this topic can be  aimed at studying the activities of individual modern Ukrainian pop performers, their creativity.

Concert of J. Brahms for violin and orchestra in the embodiment of the ideas of protoneoclassicism
Authors: Bay Liu
Published: June 2023

The purpose of the article is to study the stylistic phenomenon of proto-neoclassicism in the post-romantic art of the last third of the XIX century and to recognize those stylistic features in the Brahms Violin Concerto. The methodological basis of the work is the intonation approach of B. Asafyev's school in Ukraine, which proceeds from the sacred unity of music and words, giving birth to historical-comparative, hermeneutic, bibliographic research methods, presented in the works of O. Markova, O. Muravska, O. Roschenko. etc. The scientific novelty of the work is due to the originality of the problem of proto-neoclassicism in the art of the post-Romantic era, as well as the fact that for the first time in the musicology of Ukraine and China in this stylistic perspective considered Violin Concerto J. Brahms. Conclusions. Baroque borrowings, natural for Romanticism, are filled with superpersonal lyricism and polyphonic texture in the post-romantic space of the second half of the nineteenth century, provoking the genre solution of parts of the cycle and separation from drama and elaboration in sonata indicators of composition. These features of the interpretation of the concert can be found in the analyzed work of J. Brahms, which we terminologically distinguish as the proto-neoclassicism of J. Brahms.

Key words: J. Brahms' proto-neoclassicism, twentieth-century neoclassicism, Biedermeier, romanticism, style in music.

Migrant workers constitute a relatively large proportion of the total population in general and the labor force in particular in Ho Chi Minh City. Research on social security for this group is an issue that needs to be paid attention to, in which health insurance is one of the important policies in the social security system being applied in our country. This article will study the issue of health insurance for migrant workers. By deploying the qualitative research method, the author researches the opportunity of accessing health insurance of migrant workers in Ho Chi Minh City, in particular, using the expert method to collect opinions on the questionnaire, using the direct survey method on 512 workers to build a database for the analysis in the article. The study results show that 93% of the surveyed migrant workers have health insurance, 73% of which have access to policy benefits. However, some barriers inhibit the opportunity of participating in and benefitting from health insurance of migrant workers, such as (i) proper perception of enterprises greatly affects the participation in health insurance of employees; (ii) ignorance and lack of information of employees on the health insurance policy; (iii) inconvenience of regulations about where participants access the healthcare system; (iv) time for medical examination and treatment associated with health insurance has not created favorable conditions for employees; (v) the overcrowding of public hospitals is accompanied by a poor-quality service, diminishing the participant's trust. Specifically, the article indicates that household registration is not a factor affecting the access to health insurance of migrant workers, which is different from other studies on the same topic. That is, household registration in Ho Chi Minh City makes no difference in accessing health insurance.

Labor productivity is an important indicator to evaluate business performance. This study aims to determine the factors affecting labor productivity of workers working at Ca Mau Petroleum Fertilizer Joint Stock Company (DCM). Research data was collected through a survey of 245 workers working at Ca Mau Fertilizer and the research model was tested by the quantitative method. The research results show that all four factors affecting the labor productivity of workers, consisting of personal capacity, production management system, human resource management and internal relationships. Of the factors, the internal relationship and the production management exert the strongest influence while the individual capacity and human resource management have less impact on performance. As a result, management implications are proposed such as training and developing skills by the specificity of the industry, the development of standards to evaluate job results suitable for each job position and compensation policies, communication activities, corporate culture to improve labor productivity of workers at Ca Mau Fertilizer.
Assessment of Vietnam’s public debt in the current period
Authors:   Vietnam National University of Forestry – Dong Nai Campus, Vietnam, Tran Hung Van
Published: June 2023

The article is based on secondary data collected from the Financial Statistical Yearbook of the Ministry of Finance and utilizes descriptive statistical methods to assess the current state of Vietnam's public debt in the current period on three aspects consisting of government debt, governmentguaranteed debt, and local government debt. On that basis, the author employs indicators to evaluate the level of the public debt of Vietnam over the period 2006-2019, and assesses the sustainability and safety of Vietnam's public debt compared to those of other countries in the ASEAN region. Research results show that although public debt in Vietnam is still within the allowable ceiling, it has shown signs of increasing in recent years, and the Government has failed to reach the target of maintaining government debt at less than 50%/GDP. The main reason for the increase in government debt stems from the budget deficit, inefficient public spending and public investment, causing loss and waste of investment capital, putting Vietnam into a double deficit of high public budget deficit and spending deficit in recent years. More importantly, the public debt ratio of Vietnam is also relatively high compared to other countries in the ASEAN region, indicating that public debt is posing potential risks to the economy. On that basis, the article also analyzes the causes of high public debt, from which a number of recommendations are proposed to help control the issue in Vietnam.

Published: June 2023

Vietnam's economy, over the past 30 years, has gained great achievements, rapidly transforming Vietnam from one of the poorest countries in the world to a low-middle-income country. In 2020, although Vietnam's economy was heavily affected by the Covid-19 pandemic, natural disasters, the average economic growth rate in the five years 2016-2020 is still among the fastest-growing countries in the region and the world. The economic structure has changed with a plunge in the proportion of agriculture, forestry and fishery sector along with the increasing proportion of the service sector. This paper uses the ARIMA model to forecast the economic structure of Vietnam in 2025. The research data is the production value of the agriculture, forestry and fishery sector; the technology and construction sector and the service sector from 1987 to 2019 do not include the value of the product tax with the subtraction of product subsidies area. The steps to perform the forecast include: checking the stationary of the time series, analyzing the correlation diagram, estimating the ARIMA model, testing the hypotheses and finally forecasting the value in the year 2025 of economic sectors. The forecast results show that from 2020 to 2025, the economic structure has a strong shift from the agriculture, forestry and fishery sector along with a part of the industrial and construction sector to the service sector. Specifically, the proportion of the agriculture, forestry and fishery sector will decrease from 16% in 2019 to about 12% in 2025. The proportion of the industrial and construction sector reduces from 38% in 2019 to 36% in 2025. The service sector will increase its proportion from 46% in 2019 to 52% in 2025. Research results contribute to a quantitative basis in policy enactment and implementation at the macro and micro levels.

The explosion of information technology in general and social networks in particular has brought many choices for online users. Understanding what drives intention to continue using a social network is an important discovery. This study aims to explore the critical personal motivations that influence Gen Z's intention to continue using TikTok in Ho Chi Minh City. The research model is based on The Uses and Gratifications Theory with 5 proposed research hypotheses. In particular, social interaction motivation, archiving motivation, self-expression motivation, peeking motivation and escapism motivation has a positive effect on the intention to continue using TikTok of Generation Z users respectively. With data collected from 295 respondents, after testing for unidimentionality, reliability, and validity of measurement scales, the SEM results show that 4 out of 5 motives including motivation for social interaction, archiving, self-expression, and escapism have a statistically significant influence on the intention to continue using TikTok platform. Among these motivations, social interaction motivation is the most important factor. These results suggest helpful managerial implications not only for TikTok developers but also for companies that use TikTok as a channel to communicate with their customers.

The main regularities of the process of forming on refractory metals the single-phase, multi-phase, multi-layer composite coatings with high heat resistance and durability are examined in the article. A study of boride coating on refractory metals was conducted, which showed that a single-phase coating is formed on metals that possesses good adhesion to the base. Based on the results of X-ray phase and micro-X-ray spectral methods of analysis, the formation of a monoboride phase on molybdenum and tungsten and a boride phase on niobium and tantalum was revealed. A study of the effect of temperature on the process of diffusion silicification of refractory metals was carried out, which showed that in the range of 950–1100 0С, a single-phase coating is formed, which consists of disilicides of МеSi2 metals. A further increase in the temperature of the saturation process was found to lead to a sharp increase in the thickness of the silicide layer. It was proved that an effective diffusion barrier is the boride phases of refractory metals, which ensure the stability of the diffusion part of the multicomponent coating. The boride phases were determined to be more stable than silicide phases in relation to the metal base. Due to the formation of silicoboride phases at the border of boride and silicide layers, high stability of the borosilicide coating is ensured. The presence of penetrating impurities in the metal matrix leads to poor protection of the oxide film of the diffusion coating and, as a result, to low durability. A mechanism for the transfer of penetrating impurities from the depth of the metal to the boundary of the powder medium is proposed. The obtained borosilicate-saturated metal technological parameters allow forming a diffusion coating with a fine-grained structure on refractory metals. To ensure high protective characteristics, the formation of the layered part of the coating should be further researched.
