Authors: Jiang Xiao-Lei , Deng Xiao-Qin , Wang Yang , Lu Yi-Fei , Li Jia-Ji , Zhou Chun , Bao Wan-Su
Published: May 2022

The ideal quantum key distribution (QKD) protocol requires perfect random numbers for bit encoding and basis selecting. Perfect randomness is of great significance to the practical QKD system. However, due to the imperfection of practical quantum devices, an eavesdropper (Eve) may acquire some random numbers, thus affecting the security of practical systems. In this paper, we analyze the effects of the weak randomness in the measurement-device-independent QKD (MDI-QKD) with finite resources. We analytically derive concise formulas for estimating the lower bound of the single-photon yield and the upper bound of the phase error rate in the case of the weak randomness. The simulation demonstrates that the final secret key rate of MDI-QKD with finite resources is sensitive to state preparation, even with a small proportion of weak randomness, the secure key rate has a noticeable fluctuation. Therefore, the weak randomness of the state preparation may bring additional security risks. In order to ensure the practical security of the QKD system, we are supposed to strengthen the protection of state preparation devices.

Authors: Gryaznevich Mikhail , Chuyanov Valery A. , Takase Yuichi
Published: May 2022

Traditionally, spherical tokamak (ST) reactors are considered to operate in a steady state. This paper analyses the advantages of a pulsed ST reactor. The methodology developed for conventional tokamak (CT) reactors is used and it is shown that advantages of a pulsed operation are even more pronounced in an ST reactor because of its ability to operate at a higher beta, therefore achieving a higher bootstrap current fraction, which, together with a lower inductance, reduces requirements for magnetic flux from the central solenoid for the plasma current ramp-up and sustainment.
A Phosphorus-Nitrogen-Carbon Synergistic Nanolayered Flame Retardant for Polystyrene
Authors: Yuan Wen-Jie , Zhao Wei , Wu Gang , Zhao Hai-Bo
Published: May 2022

Polymers are widely used in our daily life; however, most of them are highly flammable. Once modified with flame retardants (FRs), polymers always have deteriorative properties in mechanical strength aspects. As a countermeasure, a novel unified phosphorus and nitrogen-containing organic nano-layered flame retardant (BA-MA) was synthesized by the assembly of biphenyl-4,4′-diphosphonic acid (BA) and melamine (MA), which was used as an additive flame retardant for polystyrene (PS) resin. The chemical structure and morphology of BA-MA were characterized, and a possible growth mechanism of the nanolayered structure was presented in detail. The resulting BA-MA with a thickness of about 60 nm can be uniformly dispersed in the PS resin, thus maintaining the mechanical properties of the material. Remarkably, under only 1 wt% loading of BA-MA, the flammability of PS can be largely reduced with a 68% reduction in the peak heat release rate. Additionally, the smoke release was also significantly inhibited. The research on flame retardant mechanisms shows that BA-MA mainly produces incombustible gas to dilute the concentration of combustibles and promote the formation of aromatic carbon layers to isolate oxygen transmission and heat transfer.

Published: May 2022

To study the contact parameters of the tobacco strips during redrying, in this study, the funnel stacking test is used to determine the stacking angle, and the discrete element method is used to simulate the formation process of the stacking angle, to calibrate and verify the physical and contact parameters of tobacco strips. The Placket–Burman test was used to screen out the parameters that had significant effects on the stacking angle. The regression response surface model between the stacking angle and contact parameters was established by Central Composite Design using the stacking angle from physical tests as the response index. The test results show that static and rolling friction coefficients between tobacco strips have significant effects on the test results, so these two parameters must be accurately calibrated. Finally, the accuracy and validity of the calibrated tobacco strips contact parameters were verified by comparing the stacking angle and void ratio of physical and simulation experiments. The calibration results can provide basic parameters for studying the interaction and motion of the tobacco strips in the redrying process using simulation methods.
Numerical Study of the Effect of the Reynolds Number and the Turbulence Intensity on the Performance of the NACA 0018 Airfoil at the Low Reynolds Number Regime
Authors: Michna Jan , Rogowski Krzysztof
Published: May 2022

In recent years, there has been an increased interest in the old NACA four-digit series when designing wind turbines or small aircraft. One of the airfoils frequently used for this purpose is the NACA 0018 profile. However, since 1933, for over 70 years, almost no new experimental studies of this profile have been carried out to investigate its performance in the regime of small and medium Reynolds numbers as well as for various turbulence parameters. This paper discusses the effect of the Reynolds number and the turbulence intensity on the lift and drag coefficients of the NACA 0018 airfoil under the low Reynolds number regime. The research was carried out for the range of Reynolds numbers from 50,000 to 200,000 and for the range of turbulence intensity on the airfoil from 0.01% to 0.5%. Moreover, the tests were carried out for the range of angles of attack from 0 to 10 degrees. The uncalibrated γ−Reθ transition turbulence model was used for the analysis. Our research has shown that airfoil performance is largely dependent on the Reynolds number and less on the turbulence intensity. For this range of Reynolds numbers, the characteristic of the lift coefficient is not linear and cannot be analyzed using a single aerodynamic derivative as for large Reynolds numbers. The largest differences in both aerodynamic coefficients are observed for the Reynolds number of 50,000.

Authors: Chang Chun-Nan , Liao Ting-Hsiu , Huang Hao-Chen
Published: May 2022

Due to its rich marine biological resources, Taiwan is a place worthy of developing marine ecotourism. This study explores the marine ecotourism intentions and marine ecotourism behaviors of tourists during the COVID-19 pandemic by using the unified theory of acceptance and use of technology (UTAUT) method. Under the UTAUT framework, this study considered the factor of environmental attitudes and issued questionnaires in four research areas, namely, Yilan Wushi Fishing Harbor, Port of Hualien, Hualien Stone Stairs Platform, and Taitung Chengfong Fishing Port. In total, 431 effective research samples were collected. First, this study verified the validity and reliability of the dimensions through confirmatory factor analysis. According to the results of structural equation modeling (SEM) analysis, performance expectancy, effort expectancy, social influence, and environmental attitude all have an influence on tourists’ marine ecotourism intentions, while facilitating conditions had no influences on tourists’ marine ecotourism intentions. Tourists’ marine ecotourism intentions further influenced their marine ecotourism behaviors. In addition, this study evaluated the mediating effect of marine ecotourism intentions by nested-model analysis. Finally, this study provided substantive policy recommendations as a reference for tourism management units and local governments.

Published: May 2022

The changes in land cover patterns in the Mongolian Plateau can reveal the regional status of sustainable development. Based on land cover data from 1990–2020, the study reveals the process of land cover change on the Mongolian plateau and integrates those changes with UN Sustainable Development Goals (SDGs) to further evaluate regional sustainable development status. Result revealed there is a stable rate of land cover change (0.16%) for the Mongolian Plateau, but with diverse shifting trends for various land cover types and SDGs indicators in past 30 years. Croplands (SDG2) showed a growth trend in the last five years, which was different from its initial obviously decreasing trend. The status of water (SDG6) showed a clear decreasing trend, which presents a major threat to this arid-to-semi-arid region. The built area (SDG11) increased continuously, but the long upward trend has slowed in recent years. The forest area (SDG15) declined, but it has recently recovered. Grasslands showed diverse changes in various steppe types (including real, meadow, and desert steppe types) while still experiencing land degradation. The expansion of sand areas presents a hidden risk of increasing sandstorms. Comparative analysis revealed that there have clear differences between Mongolia and Inner Mongolia due to the various government policies. In general, the land use degree in Mongolian Plateau increased annually. This indicated that the climate change and human activities have more and more influences, and it is still facing severe challenges for specific SDGs indicators in the region.
Exploring and Addressing the User Acceptance Issues Embedded in the Adoption of Reusable Packaging Systems
Authors: Long Yuan , Ceschin Fabrizio , Harrison David , Terzioğlu Nazlı
Published: May 2022

Plastic in the linear consumption model is frequently manufactured and disposed of, leading to the creation of excessive plastic waste, which has significant consequences for the environment. Single-use food packaging waste is a large constituent of plastic waste that needs to be addressed urgently. The implementation of reusable packaging systems (RPSs) to close the loop of consumption appears to be promising, but the insights into consumers’ willingness to accept them are limited. This research investigates the aspect of consumers’ adoption of RPSs by identifying the particular user acceptance issues and eventually providing a set of design recommendations to address them. The data collection methods are remote interviews, engaging with 42 participants in three iterations, to evaluate three user experiences of RPSs in order to identify the user acceptance issues. After the user acceptance issues are identified in each iteration, the Theory of Attitude-Behaviour-Context is employed to advance the understanding of the acceptance issues. In order to continuously refine the user experiences, insights from design for sustainable behaviour are applied to address the user acceptance issues. The research results include three refined user experiences, four user acceptance issues—namely hygiene, usability, finance and motivation—and design recommendations to address those user acceptance issues. This research may be of interest to packaging professionals, and could be used to design and refine the RPSs to induce consumers’ adoption.
To What Extent May Transit Stop Spacing Be Increased before Driving Away Riders? Referring to Evidence of the 2017 NHTS in the United States
Authors: Wu Telan , Jin Hui , Yang Xiaoguang
Published: May 2022

With the emergence of ride-sourcing and ride-splitting services, more options are available to support shifts away from transit, where maintaining transit ridership increases requirements for transit service quality, so as to promote high-capacity and sustainable transport systems. In this endeavor, proper transit stop spacing is critical for both service accessibility and in-vehicle trip efficiency, as well as operation cost. This research explores acceptable stop spacing for three kinds of transit services from the perspective of travel behavior, drawing on the 2017 National Household Travel Survey in the United States. A stochastic frontier model is developed to infer passengers’ unobservable vertex of acceptable transit access times on the basis of observed walk time, which can be converted to the tolerance with respect to stop spacing with the average walking speed. Significant explanatory variables on the vertex of acceptable transit stop spacing are further identified with their quantified impacts, including household density, household income, wait time, trip distance, transfer, and maintenance purpose, while the inefficiency variance is significantly related to traveler age, wait time, secondary walk time, and trip frequency. Recommended response strategies follow. Findings from this study provide insights, guidelines, and implementation plans for different transit agencies when considering stop spacing redesign, to strengthen transit service appeal and to promote cooperative and sustainable multi-modal urban transport systems.
A Validated Model, Scalability, and Plant Growth Results for an Agrivoltaic Greenhouse
Authors: Evans Michael E. , Langley J. Adam , Shapiro Finley R. , Jones Gerard F.
Published: May 2022

We developed an agrivoltaic greenhouse (a ‘test cell’) that partially trapped waste heat from two photovoltaic (PV) panels. These panels served as parts of the roof of the enclosure to extend the growing season. Relative humidity, internal air temperature, incident solar radiation, wind speed, and wind direction were measured for one year. A locally 1-D transient heat and moisture transport model, as well as a shadowing model, was developed and validated with experimental data. The models were used to investigate the effects of altering various parameters of the greenhouse in a scalability study. The design kept test cell air temperatures generally above ambient throughout the year, with the test cell temperature below freezing for 36% less of the year than ambient. Plant growth experiments showed that kale, Brassica oleraceae, a shade-tolerant plant, can be grown within the test cell throughout the winter. The simulations showed that enlarging the greenhouse will increase cell air temperatures but that powering an electric load from the PV panels will reduce cell air temperatures.
A Classification Model with Cognitive Reasoning Ability
Authors: Wang Jinghong , Zhang Daipeng , Liang Lina
Published: May 2022

In this paper, we study the classification problem of large data with many features and strong feature dependencies. This type of problem has shortcomings when handled by machine learning models. Therefore, a classification model with cognitive reasoning ability is proposed. The core idea is to use cognitive reasoning mechanism proposed in this paper to solve the classification problem of large structured data with multiple features and strong correlation between features, and then implements cognitive reasoning for features. The model has three parts. The first part proposes a Feature-to-Image algorithm for converting structured data into image data. The algorithm quantifies the dependencies between features, so as to take into account the impact of individual independent features and correlations between features on the prediction results. The second part designs and implements low-level feature extraction of the quantified features using convolutional neural networks. With the relative symmetry of the capsule network, the third part proposes a cognitive reasoning mechanism to implement high-level feature extraction, feature cognitive reasoning, and classification tasks of the data. At the same time, this paper provides the derivation process and algorithm description of cognitive reasoning mechanism. Experiments show that our model is efficient and outperforms comparable models on the category prediction experiment of ADMET properties of five compounds.This work will provide a new way for cognitive computing of intelligent data analysis.

Authors: He Aaron W. J. , Ngai Shirley P. C. , Cheung Kwok Kuen , Lau Benson W. M. , Sánchez-Vidaña Dalinda-Isabel , Pang Marco Y. C.
Published: May 2022

Cigarette smoke (CS) is the major risk factor for chronic obstructive pulmonary disease (COPD) and can induce systemic manifestations, such as skeletal muscle derangement. However, inconsistent findings of muscle derangement were reported in previous studies. The aim of the present study was to consolidate the available evidence and assess the impact of CS on muscle derangement in rodents. A comprehensive literature search of five electronic databases identified ten articles for final analysis. Results showed that the diaphragm, rectus femoris, soleus, and gastrocnemius exhibited significant oxidative to glycolytic fiber conversions upon CS exposure. In contrast, the extensor digitorum longus (EDL), plantaris, and tibialis did not exhibit a similar fiber-type conversion after CS exposure. Hindlimb muscles, including the quadriceps, soleus, gastrocnemius, and EDL, showed significant reductions in the CSA of the muscle fibers in the CS group when compared to the control group. Changes in inflammatory cytokines, exercise capacity, and functional outcomes induced by CS have also been evaluated. CS could induce a shift from oxidative fibers to glycolytic fibers in high-oxidative muscles such as the diaphragm, rectus femoris, and soleus, and cause muscle atrophy, as reflected by a reduction in the CSA of hindlimb muscles such as the quadriceps, soleus, gastrocnemius, and EDL.

Published: May 2022

Early identification of adaptive mutations could provide timely help for the control and prevention of the COVID-19 pandemic. The fast accumulation of SARS-CoV-2 sequencing data provides important support, while also raising a great challenge for the recognition of adaptive mutations. Here, we proposed a computational strategy to detect potentially adaptive mutations from their fixed and parallel patterns in the phylogenetic trajectory. We found that the biological meanings of fixed substitution and parallel mutation are highly complementary, and can reasonably be integrated as a fixed and parallel (paraFix) mutation, to identify potentially adaptive mutations. Tracking the dynamic evolution of SARS-CoV-2, 37 sites in spike protein were identified as having experienced paraFix mutations. Interestingly, 70% (26/37) of them have already been experimentally confirmed as adaptive mutations. Moreover, most of the mutations could be inferred as paraFix mutations one month earlier than when they became regionally dominant. Overall, we believe that the concept of paraFix mutations will help researchers to identify potentially adaptive mutations quickly and accurately, which will provide invaluable clues for disease control and prevention.
Removal of Trichloroethylene from Water by Bimetallic Ni/Fe Nanoparticles
Authors: Liu Xiaonan , Wu Minghong , Zhao Jian
Published: May 2022

Chlorinated organic solvents (COSs) are a significant threat to human beings. In this study, nanoscale bimetallic Ni/Fe particles were synthesized from the reaction of sodium borohydride (NaBH4) with the reduction of Ni2+ and Fe2+ in an aqueous solution. The synthesized nanoscale zero-valent iron (nZVI) and Ni-nZVI were characterized by SEM (scanning electron microscopy), XRD (X-ray diffractometer), Brunauer–Emmett–Teller (BET), and transmission electron microscopy (TEM). The removal performance of trichloroethylene (TCE) over the nZVI catalyst and Ni-nZVI was evaluated. Ni-nZVI with different Ni contents exhibited good reactivity towards the dechlorination of TCE over a 1h period, and the pseudo-first-order rate constant for TCE dechlorination by Ni-nZVI was 1.4–3.5 times higher than that of nZVI. Ni-nZVI with 5 wt% Ni contents exhibited the best dechlorination effect; the removal rates of TCE and its by-product dichloroethylene (DCE) were 100% and 63.69%, respectively. These results indicated that the Ni nanoparticles as the second dopant metal were better than nZVI for TCE degradation. This determination of the optimal Ni-NZVI load ratio provides a factual and theoretical basis for the subsequent application of nano-metal binding in the environment.
Simplified Uncertainty Bounding: An Approach for Estimating Flood Hazard Uncertainty
Authors: Stephens Tim , Bledsoe Brian
Published: May 2022

Deterministic flood hazard estimates neglect the inherent uncertainty associated with model estimates and can substantially underestimate flood risk. Monte Carlo simulation (MCS) has been a valuable tool for conducting uncertainty analysis. However, its application has primarily been limited to a single research setting. Recent development of a point approximation method, simplified uncertainty bounding (SUB), simulated the uncertainty from MCS with high accuracy (e.g., a critical success index of 0.75). However, an evaluation of additional flood hazard metrics and hydro-climate settings that impact the distribution of uncertainty is required. We evaluated SUB at two contrasting study sites by comparing their results with MCS and identified scenarios where performance increased and decreased. The SUB method accurately matched aerial inundation metrics, but performance was reduced for relative errors in flood depth and top width. Hydraulic structures had a heterogeneous impact on accuracy, and the confinement ratio had a positive relationship with the top width error. While SUB generally performed well with relative errors of approximately ±10% for a 90% confidence interval, some outliers did exist. The acceptability of the approach will depend on the specific application. Though SUB overestimated uncertainty, it provides a conservative estimate and is a cost-effective alternative to MCS.

Published: May 2022

Rapid urbanization and economic development in coastal regions have significantly increased coastal nutrient pollution and remarkably changed the phytoplankton community and developed some species into bloom, resulting in large economic losses and serious threats to public health. Therefore, it is indispensable to reveal the shift in the phytoplankton community and phytoplankton abundance, and phytoplankton’s environmental drivers. However, previous studies could not present the details of the environmental drivers of phytoplankton due to samples being collected with low temporal resolution. Here, high-temporal-resolution (daily) samples were collected to investigate the influence of environmental factors on phytoplankton in Qinhuangdao for 44 days. Phytoplankton communities showed a rapid succession, with predominant genera changing in the order Skeletonema–Chaetoceros–Skeletonema–Thalassiosira. Similarly, Thalassiosira pacifica, Skeletonema costatum, Chaetoceros tortissimus, and Chattonella marina were identified as the dominant species and were abundant in 0–1.27 × 107 cells·L−1, 0–9.34 × 106 cells·L−1, 0–6.49 × 106 cells·L−1, and 0–3.64 × 106 cells·L−1, respectively. Moreover, inflows facilitate the rapid succession of the phytoplankton community. Dissolved inorganic phosphorus (DIP) was found to remarkably influence the succession of phytoplankton communities and the bloom of the top three dominant species, i.e., Thalassiosira pacifica, Skeletonema costatum, and Chaetoceros tortissimus. Overall, our results provide high-temporal-resolution observations of phytoplankton community succession and reveal its environmental drivers. This contributes to our current understanding of the occurrence of algae blooms and supports the development of management strategies to control algae bloom in coastal waters.

The article is devoted to topical problems of the application of the norms of the institution of material responsibility. It is especially important to draw the legislator's attention to the need for greater protection of the employer's property rights, since in the current Labor Code of the Russian Federation, most of the rules governing material liability are aimed exclusively at protecting the interests of the employee, which is due to his dependent position in labor relations. But the employer must be fully protected, otherwise, this will lead to ignoring the tasks of labor legislation by the law enforcement officer. The purpose of this study is to formulate proposals for changes in legislation that would equally protect the rights of workers and employers.

Programs of preventive measures of Rostrud: state and prospects of exercising powers to prevent violations of labor rights
Authors:   Kuban State Agrarian University, Krasnodar, Sapfirova A.A.
Published: May 2022

Modern legislation on the implementation of the supervisory function by Rostrud is aimed at preventing violations of labor rights. It is proved that these measures constitute the main purpose of state supervision, that is, the prevention of violations of labor rights and their subsequent protection, and not only the protection of labor rights on the revealed facts of their violation. Preventive measures are carried out by Rostrud in accordance with the Harm Risk Prevention Programs. The article analyzes the data of the program for 2018–2021, in which the main direction of preventive work is to increase the awareness of the population in the field of protection of labor rights and compliance with labor legislation. The author investigates the ways of informing employers and employees about the observance of mandatory labor requirements. An analysis of the new Federal Law “On State Control (Supervision) and Municipal Control in the Russian Federation” allowed the author to propose a classification of Rostrud's preventive measures into mandatory and additional measures.

Published: May 2022

The author considers extrajudicial forms of protection of the employee's labor rights, not provided for in Art. 352 of the Labor Code of the Russian Federation. Analyzing the title of the article and its content, the author concludes that the title of the article does not correspond to its content, and therefore a change in the title of the article is proposed. Analyzing such a form of protection of the employee's labor rights as direct negotiations with the employer, the author draws attention to gaps in the legislation regarding the timing of their implementation and the legal mechanism for fixing them, in this regard, proposals are made to supplement the Labor Code of the Russian Federation. As the main reason for the low number of referrals to mediation in individual labor disputes, the author identifies her compensation for the employee, and therefore proposes to exempt the employee from the costs of paying for the mediation procedure. The article also considers the prospects for using the “complex” as a form of protection of the employee's labor rights.

Authors:   National Research University ", Pavlovskaya O.Yu. ,   Higher School of Economics",   , Moscow
Published: May 2022

The article is devoted to the issue of ensuring the right to representation and the right to unite employees by creating digital trade unions. The analysis of the practice of the Trade Union of Public Education and Science Workers of the Russian Federation on the transition to a single electronic database (platform) leads the author to the conclusion that the digital trade union in modern conditions is an effective means of implementing the statutory functions and protecting the social and labor rights of trade union members. The article also reflects the problems of creating digital trade unions at enterprises using non-standard forms of employment: the majority of non-standard employees are not members of a trade union, which deprives them of the opportunity for appropriate protection from trade union organizations. And with the growth of non-standard forms of employment, there is a reduction in solidary participants in labor relations, and a reduction in subsidiary ones. In addition, there is a tendency to reduce the total number of trade union organizations, as clearly evidenced by trade union statistics.

The current investigation presents the state and prospects for the development of the American paddlefish aquaculture in the world and Russia. The history of American paddlefish culture as a promising invasive species was recorded outside its native ranges in Russia and around the world, especially, Eastern Europe and China. The leading role of the successful Russian trials during the Soviet Union era in the central and southern regions of the country had a significant impact in preserving this species off extinction and even developing the prospects for its cultivation. The historical data on the first three shipments of paddlefish planting material in the 1970s from the United States to the Soviet Union, the stages of acclimatization of this species and the issuance of Russian scientists who made a significant contribution to the development of this fish breeding object are described in detail. The article presents the current state of paddlefish aquaculture, it is indicated that in the presence of a number of restrictions for the large-scale development of paddlefish aquaculture in the country, there are currently about 20 farms engaged in this fish farming object, both for the purpose of experimental and breeding activities, and for obtaining marketable products. But at the same time, it is extremely difficult to judge the state of paddlefish aquaculture due to the lack of statistical data on production volumes from farms, private ownership, which makes it difficult to assess the main fish-breeding indicator — fish productivity of pond areas. Unfortunately, despite a number of advantages of paddlefish for cultivation in water bodies of Russia, aquaculture of this fish species still does not receive proper development for many reasons, and primarily due to the lack of effective technologies for processing marketable fish for the production of gourmet products and extremely weak marketing and advertising activities.

Published: May 2022

Purpose: Traditional therapeutic approaches to the surgical management of hemorrhoid disease such as hemorrhoidectomies are plagued with severe postoperative pain and protracted recovery. Our pilot study aims to the laser hemorrhoidoplasty (LH) patients with symptomatic hemorrhoid disease that have failed conservative management for the first time in an Australian population. Methods: Thirty patients were prospectively enrolled to undergo LH. Postoperative pain, time to return to function, and quality of life (QoL) were determined through the Hemorrhoid Disease Symptom Score and Short Health Scale adapted for hemorrhoidal disease and compared to a historical group of 43 patients who underwent a Milligan-Morgan hemorrhoidectomy by the same surgeon at 3, 6, and 12 months. Results: The LH group had significantly lower mean predicted pain scores on days 1 and 2 and lower defecation pain scores and lower opioid analgesia use on days 1, 2, 3, and 4. The median time to return to normal function was significantly lower in the LH group (2 days vs. 9 days, P<0.001). Similarly, the median days to return to the workplace was significantly lower in the LH group (6 days vs. 13 days, P=0.007). During long-term follow-up (12 months), hemorrhoid symptoms and all QoL measures were significantly improved, especially among those with grade II to III disease. Conclusion: This pilot study demonstrates low pain scores with this revivified procedure in an Australian population, indicating possible expansion of the therapeutic options available for this common condition. Further head-to-head studies comparing LH to other hemorrhoid therapies are required to further determine the most efficacious therapeutic approach.

Method: Cross-sectional descriptive research, combined use of the method of dosing and dosing; desk study combined with a field study of 543 workers in private health facilities established and not yet established trade unions in Hanoi, Ho Chi Minh and Da Nang. Result: in 2019, private health facilities tended to increase by 14.5% compared to 2018, but only 0.65% of trade unions were established. Statistics of private health facilities have not been agreed upon between the Department of Health and the Confederation of Labor. Employees participating in trade union organizations benefit more than workers in organizations that have not participated in trade unions on social insurance, health insurance, accident insurance and toxic benefits and liability benefits. Of the interviewees 74.9% wanted workers’ representative organizations to better protect workers; 71.9% said they did not want an organization representing non-union workers in private health facilities and 22.7% did not know their position or views. Regarding the method of gathering trade union members, more than 70% of the candidates said that they must combine two methods from the bottom up and from the top down. Conclusion: the innovation of the method of gathering workers in private health facilities is an urgent requirement for trade unions at all levels.
National vocal tradition as a synthesis of composers’ and performance art (on the example of A. Ginastera’s creativity)
Authors: Wang Sige
Published: May 2022

Statement of the problem. The study of the processes of synthesis of composers’ and performance arts is one of the relevant areas of modern music science. An important aspect of their manifestation is the national tradition, which has its own characteristics in different historical and cultural conditions. This is especially true of national music representing countries that are far from the European continent. These include Argentine music, in particular, the vocal one. The analysis of publications on the chosen topic shows that the issue of national manifestations in the art of music remains acute. In addition to academic musicological research (Lyashenko; Romaniuk), there are scientific works on the border of science and journalism (Gottlieb; Kelly & Mantere & Scott; Knox), where the context is modern cultural and civilizational processes. The study of national traditions, including vocal ones, in A. Ginastera’s music (Brakhman & Kononets; Dotsenko; Kryazheva; Chase; Schwartz-Kates; Carballo; Wylie) is mostly based on the analysis of the composer’s creative work, while the performance component is insufficiently studied. All the above determines the scientific novelty of the presented research, which has the purpose to reveal the composers’ and performance principles of A. Ginastera’s vocal creative work in the context of the specifics of the Argentine national vocal tradition. The methodological basis of the research units several thematic areas:the researches devoted to Argentine music (Kryazheva; Riggs; Schwartz-Kates), to the life and creative work of A. Ginastera (Brahman & Kononets; Dotsenko; Kryazheva; Carballo; Chase; Schwartz-Kates; Wylie), and to the issues of national traditions in composer and performance creativity (Lyashenko; Romaniuk; Kelly & Mantere & Scott), in particular, in the perspective of performance analysis (Nikolaievska). Results and conclusions of the research. In vocal music, national specificity reveals at several levels – the author-composer’ one (intoning, means of expression, stylistics), the stylistic one (historical, national, and musical style), the figurative-content one (more broadly – the cultural-mental one), and the phonic-articulatory one. A. Ginastera’s vocal creative work is a special synthesis of composer and performance rethinking of traditional Argentine music at the intonation and image level, which became the core of the Argentine national vocal tradition as a manifestation of the national “picture of the world”.

The observation results show that there is no teaching material in the form of modules used by mathematics teachers at SMAN 1 Painan. Based on the problems and research objectives, this type of research is a quasi experiment. This research was conducted on two groups, namely the experimental class using guided inquiry-based modules and the control class using conventional learning. The population in this study were all students of class X MIA SMAN 1 Painan for the academic year 2020/2021 which consisted of 5 classes. To get the sample class, namely the experimental and control classes, the random sampling technique was used. Class X.MIA 4 was chosen as the experimental class and class X.MIA 3 was chosen as the control class. The instrument used was a test consisting of 5 questions on concept understanding tests. The data analysis used the t test because the data were normally distributed and homogeneous. Based on the results of the hypothesis test, a significance level of 0.0035 was obtained. It means that Ho is rejected, this means that the understanding of students' mathematical concepts taught by using guided inquiry-based modules is better than conventional learning

This study originated from the findings of researchers who indicated that there were problems in the implementation of inclusive learning in 91 SMA and SMK in West Sumatra. This study aims to examine the suitability of Permendiknas Number 70 of 2009 with the implementation of learning in schools. This study uses a qualitative method. Data collection techniques in the form of observation, interviews and documentation. The research setting was at 4 SMA and SMK in West Sumatra, with informants consisting of 10 people, 1 principal, 2 curriculum representatives, 3 subject teachers, 2 BK teachers, and 2 GPK people from four different SMA and SMK. The results of the study found three general findings and four specific findings. Namely the implementation of identification, assessment, PPI, flexible curriculum, evaluation and assessment of learning outcomes. The obstacles encountered are grouped into four sections, from the government, from school leaders, from teachers, and from students. The government has issued guidelines containing guidelines and regulations. It turned out that the results were not in accordance with the phenomena in the field, and there was a paradox (the expectations were not matched with the reality that had happened). Therefore the researchers suggest that the implementation of inclusive learning in SMA and SMK consistently implement the Minister of Education Regulation Number 70 of 2009. If the organizers of inclusive learning are not consistent, the implementation of inclusive learning is just wishful thinking.
