Microbiolization of soybean seeds with Trichoderma harzianum: physiological and sanitary quality
 
ABSTRACT: Soybean (Glycine max L.) contributes to the generation of foreign exchange via exports, considered the most important agricultural crop in Brazil. The objective was to analyze the use of T. harzianum for microbiolization of soybean seeds, aiming at the biological control of fungi. The seeds used were from the cultivars BRS 523 and BRS 539, where the treatments were characterized through a completely randomized design. For the sanity test, the treatments used were the control, chemical treatments (dicarboximide) and biological treatments divided into concentrations of 50, 100, 150, 200, 250, 300, 350 and 400 g of T. harzianum. 100-1 kg of seeds. In the germination test, the same sanity treatments were used, evaluating the percentage of germination, first count, dead and hard seeds, and seedling length. Regression analysis was carried out for the quantitative data with the significance of the models verified by the F test. Therefore, the application of T. harzianum at the maximum concentration (400 g) used on soybean seeds obtained greater efficiency in the reduction of Aspergillus flavus, Fusarium semitectum, Penicillium sp. and Colletotrichum truncatum. The high concentrations (350 g and 400 g) of T. harzianum provided a 2% increase in the germination of the soybean cultivar BRS 539.

Published: July 2023

This research was conducted to examine the socially responsible leadership (SRL) perceptions of university students, which are thought to be directly related to social developments. The survey method, one of the quantitative research methods, was used in the study. The sample consisted of 73 female and 134 male (Age Mean: 22.19±3.307) students studying at the faculty of sports sciences. The “Socially Responsible Leadership Scale-SRL” developed by Tyree (1998) and adapted to Turkish by Külekçi and Özgan (2015) was used as a measurement tool. Descriptive statistics, t-test, and ANOVA were used in the analysis. It was found that students' SRL perception was high. While the variables of gender, grade level, and taking social service course showed statistically significant differences, no statistically significant differences were found between other variables and sub-factors. It has been determined that as the age and grade level increase and the status of doing sports is positive, students' perception of socially responsible leadership also increases. The results obtained in this research reveal the importance of education and sports. The fact that the courses given on socially responsible awareness in universities, the number of projects, and the positive situation of individuals doing sports make us think that university students are also effective in increasing their perception of socially responsible leadership, and it is expected that the research will contribute to socially responsible leadership studies in the field of sports sciences.

Purpose. To give expert assessment of production and professional risks at plants and factories. Methodology. There are many different methods of assessing industrial and occupational risks. Among them, it is hardly possible to single out some universal method that would be suitable for all organizations. Therefore, specialists choose the method of risk assessment independently. This article considers the possibilities of applying expert assessment methods in the analysis of industrial and professional risks. Methods of expert evaluation have been briefly outlined, which can be divided into two groups: individual and collective, and it has also been shown that the methods of expert evaluation are a way of forecasting and evaluating future results as well as the actions based on the forecasts of specialists. Results. It has been indicated that occupational risk is a risk that covers each of all dangers that may exist in the company during the development of normal activities, that the prevention of these risks consists of a set of prevention plans and measures that are carried out in plants, factories and in companies to prevent risky situations. In this way, the danger or risk that the activity presents to the employee must be eliminated or reduced. Practical significance. It has been shown that the production risk is defined as the risk associated with the manufacturing of products, goods, services, and with the implementation of any type of production activity, in the process of which entrepreneurs face the problems of inadequate use of raw materials, increase in cost price, increase in loss of working time, inefficient use of new methods of production. The main reasons for the production risk of a company or of a product manufacturer have been indicated. A brief explanation of qualitative and quantitative risk assessment, requirements for the expert commission and the experts themselves has been given.

Authors: Vasilchenkо A. V. , Prakh S. V. , Podgornaya M. E.
Published: July 2023

The long-term analysis of the entomocomplex of plum orchards, carried out in Krasnodar Territory, revealed variations in the quantitative composition of entomofauna of harmful species and the level of their harmfulness. It was established that, in the period from 2005 to 2021, the rotation of dominant and secondary species occurred. The main species included plum Grapholitha funebrana Treitschke and oriental Grapholitha molesta Busck fruit moths, plum black Haploca minuta Christ. and yellow Hoplocampa flava L. sawflies, plum aphid Hyalopterus pruni Geoffr. and twospotted spider mite Tetranychus urticae Koch. Associated species included plum gall Acalitus phloeocoptes (Nal.) and hawthorn Tetranuchus viennensis Zacher. mites, fruit-tree Tibicina haematodes Scopoli and citrus flatid Metcalfa pruinosa (Say) planthoppers and leaf roller moths of Tortricidae family. The group characterised by a limited distribution area includes the Californian Quadraspidiotus perniciosus Comst. and Turanian Diaspidiotus prunorum Laing. scales, plum Sphaerolecanium prunastri Fonsc and European brown Parthenolecanium corni Bouche. scales, seed wasps Eurytoma amygdali End., brown marmorated stinkbug Halyomorpha halys (Stål) and secondary insects (unequal bark beetle Xyleborus dispar F., fruit tree bark beetle Scolytus rugulosus (P.W.J. Müller), wood leopard moth Zeuzera pyrina L). When considering the structure formation of phytophage complex according to phylogenetic specialization, taking into account trophic relationships, it was established that the proportion of polyphages is 2.5 times higher than that of oligophages and 8.5 times higher than that of monophages from the total number of registered pest species. In the past decade, a reduction of pesticide load in plum agrocenoses has been observed due to the wider use of agrotechnical methods and the inclusion of bioregulatory and biological insecticides into protection systems, which contributed to the preservation and increase of beneficial fauna. Entomophages constitute 7–10% of the total number of entomoacrocenosis dominated by Hymenoptera and Coleoptera classes and mites of Acari subclass. The long-term monitoring of species composition, rotation of dominant and secondary pest species and entomophages, variations in their number and harmfulness, seasonal dynamics, trophic relationships of plum entomoacrocenosis under varying environmental conditions and increasing intensification of agricultural production expand the possibility of phytosanitary optimisation strategy of perennial agrocenoses in the south of Russia. This contributes to the preservation of regional biodiversity, as well as to the stable production of high-quality ecologically safe products with minimal negative impact on the environment.

Un paradigma en potencia: los verbos de ascenso evidenciales y admirativos en la historia del inglés
Authors:   Universidad Complutense de Madrid, Serrano Losada Mario
Published: July 2023

A partir de dos estudios de caso concretos –la obsolescencia de chance y el surgimiento de turn out– el presente estudio aborda, por un lado, la creciente paradigmatización de los verbos de ascenso evidenciales y admirativos del inglés y, por otro, explora los distintos procesos cognitivos involucrados en el surgimiento y obsolescencia de los miembros de esta categoría incipiente. Así, los datos diacrónicos revelan que este conjunto de verbos ha desarrollado características y patrones construccionales comunes que permiten considerarlos un paradigma emergente. De hecho, la obsolescencia y surgimiento de los verbos analizados apuntan a una compleja evolución en la que las diferentes construcciones están sofisticadamente imbricadas: a medida que han surgido nuevos verbos evidenciales y admirativos, los miembros preexistentes de esta categoría han sufrido importantes modificaciones para dar cabida a los recién llegados. Así, la incorporación de turn out en el siglo xviii como nuevo miembro a la clase tuvo importantes repercusiones en el sistema que resultaría en la desaparición de chance. El estudio de esta red de expresiones desde un punto de vista construccional nos permite rastrear su compleja historia desde una perspectiva amplia, además de arrojar luz sobre procesos como la analogización, la construccionalización y la paradigmatización. El artículo se basa en datos de diversos corpus de inglés, sincrónicos y diacrónicos, incluyendo COCA, EEBOCorp o CLMET, entre otros.

A Study on the Correlation between Changes in North Korea's Power Structure and Constitutional Amendments
Authors:   Korea Society of Unification & North Korean Law Studies(North Korean Law Society), Cho Jae Hyun
Published: July 2023

The Constitution of North Korea was enacted and promulgated on September 8, 1948 as the People's Democratic Constitution, and the Socialist Constitution of the Democratic People's Republic of Korea was newly adopted on December 27, 1972, including the 2019 Constitution, which did not guarantee basic human rights such as life, liberty, and property of all people, or operate as a norm to control and limit the supreme power of the state. From a legal normative perspective, North Korea's supreme authority exists beyond the constitution and is not bound by the law, and he has no real limits to the exercise of his constitutional powers. It can be said to be a state system in which the policies of the party and the state and the state's official governance system, such as the constitution, must coincide with the will of the leader, the sole leader. Likewise South Korean rulers in the past amended the Constitution with political intentions to prolong the regime, this paper attempted to examine what the political implications of the supreme power in North Korea's constitutional amendment there were, and find out what role the Constitution played in establishing the hereditary system leading to Kim Il-sung, Kim Jong-il, and Kim Jong Un. In addition, it was a question about the North Korea system, how it gave legitimacy to the power succession by using the constitutional normative power for the unique national hereditary succession by blood in the socialist system. For this purpose, in particular, this paper employed North Korea's 1992 constitutional amendment, Kim Jong-il's succession to power, Kim Il-sung's posthumous rule and 1998 constitution, and Kim Jong-il's posthumous Kim Il-sung--Kim Jong-il's constitution as the main subject of research. To understand the correlation between changes in the power structure of North Korea and the constitution, this paper tried to investigate first of all, what there are in the contents of the constitutional paving stone for the succession of Kim Jong-il and Kim Jong Un, and find out Kim Jong-il's posthumous rule developed after Kim Il-sung's death and the intention of constitutionalization work for the deceased Kim Il-sung, and examine how the constitutional acceptance of the newly emerged state guidance guidelines was along with the hereditary succession of state power, and what intention there was in the constitutional reflection of the governing philosophy by deleting the previous highest state position and changing the new state position. It was because of the political intention shown in the amendment of the North Korea Constitution and the desire to approach the practical legal and normative environment of North Korea.
Analysis and Evaluation of North Korea’s Human Rights Policy around 2020: focused on enactment and revision of social control laws
Authors:   Korea Society of Unification & North Korean Law Studies(North Korean Law Society), Lee Kyu Chang
Published: July 2023

North Korea enacted a Countermeasure Act that could respond by considering the international community’s accountability activities and human rights sanctions as defamation against North Korea and that established a crime of defamation on DPRK in the criminal law. In response to COVID-19, North Korea revised the Law on Prevention of Infectious Disease and enacted the Emergency Quarantine Law. By enforcing these laws, North Korea excessively regulated and punished North Koreans. Also North Korea strengthened controls and rules by tightening discipline within the WPK through punishment and reshuffles of officials. Especially North Korea strengthened ideological, information and culture control through enacting Public Report Act, Reactionary Ideology and Culture Rejection Act, Youth Education Security Act, Pyongyang Standard Language Protection Act and Law on the Administration of Revolutionary Relics. And control and punishment of drugs was strengthened through the revision of the Criminal Law and enactment of the Drug Crime Prevention Act. Meanwhile, North Korean authorities have continuously issued an order to ban human rights violations since COI establishment and then enacted Act on Prevention of Batteries. This indicates that international community’s consistent human rights policy toward North Korea can draw reality change and legislative change. Also in order to drawing North Korea’s change, international community continue information and culture dissemination activities.
The Effects of Subthalamic Nucleus Deep Brain Stimulation and Retention Delay on Memory-Guided Reaching Performance in People with Parkinson’s Disease

Published: July 2023

Background:

Subthalamic nucleus deep brain stimulation (STN-DBS) improves intensive aspects of movement (velocity) in people with Parkinson’s disease (PD) but impairs the more cognitively demanding coordinative aspects of movement (error). We extended these findings by evaluating STN-DBS induced changes in intensive and coordinative aspects of movement during a memory-guided reaching task with varying retention delays.

Objective:

We evaluated the effect of STN-DBS on motor control during a memory-guided reaching task with short and long retention delays in participants with PD and compared performance to healthy controls (HC).

Methods:

Eleven participants with PD completed the motor section of the Movement Disorder Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS III) and performed a memory-guided reaching task under four different STN-DBS conditions (DBS-OFF, DBS-RIGHT, DBS-LEFT, and DBS-BOTH) and two retention delays (0.5 s and 5 s). An additional 13 HC completed the memory-guided reaching task.

Results:

Unilateral and bilateral STN-DBS improved the MDS-UPDRS III scores. In the memory-guided reaching task, both unilateral and bilateral STN-DBS increased the intensive aspects of movement (amplitude and velocity) in the direction toward HC but impaired coordinative aspects of movement (error) away from the HC. Furthermore, movement time was decreased but reaction time was unaffected by STN-DBS. Shorter retention delays increased amplitude and velocity, decreased movement times, and decreased error, but increased reaction times in the participants with PD. There were no interactions between STN-DBS condition and retention delay.

Conclusion:

STN-DBS may affect cognitive-motor functioning by altering activity throughout cortico-basal ganglia networks and the oscillatory activity subserving them.

Published: July 2023

Background:

Multiple system atrophy (MSA) is an intractable neurodegenerative disorder with poorly understanding of prognostic factors.

Objective:

The purpose of this retrospective longitudinal study was to explore the main predictors of survival of MSA patients with new clinical subtypes based on cluster analysis.

Methods:

A total of 153 Chinese MSA patients were recruited in our study. The basic demographic data and motor and nonmotor symptoms were assessed. Cluster and principal component analysis (PCA) were used to eliminate collinearity and search for new clinical subtypes. The multivariable Cox regression was used to find factors associated with survival in MSA patients.

Results:

The median survival time from symptom onset to death (estimated using data from all patients by Kaplan-Meier analysis) was 6.3 (95% CI = 6.1–6.7) years. The survival model showed that a shorter survival time was associated with motor principal component (PC)1 (HR = 1.71, 95% CI: 1.26–2.30, p < 0.001) and nonmotor PC3 (HR = 1.68, 95% CI: 1.31–2.10, p < 0.001) through PCA. Four clusters were identified: Cluster 1 (mild), Cluster 2 (mood disorder-dominant), Cluster 3 (axial symptoms and cognitive impairment-dominant), and Cluster 4 (autonomic failure-dominant). Multivariate Cox regression indicated that Cluster 3 (HR = 4.15, 95% CI: 1.73–9.90, p = 0.001) and Cluster 4 (HR = 4.18, 95% CI: 1.73–10.1, p = 0.002) were independently associated with shorter survival time.

Conclusion:

More serious motor symptoms, axial symptoms such as falls and dysphagia, orthostatic hypotension, and cognitive impairment were associated with poor survival in MSA via PCA and cluster analysis.

Authors: Yadav Sugandha , Mittal Poornima , Negi Shubham
Published: July 2023

In consumer electronics, Organic LED (OLED) has become mainstream display technology. Using organic materials, opto-electronics devices have become extensively desirable for various reasons. One of the fundamental properties i.e., flexibility permits to fabricate electronic circuits on flexible substrates to make these devices bendable and stretchable. This paper provides a review on various terms of OLED like fabrication methods, operation of OLED, its categorization, few OTFT driven OLEDs, stability issues of white OLED and various applications of OLED based on sensors, display, and lighting. Different lighting devices like incandescent bulb, tube light, CFL, LED and OLED are compared on the basis of their efficiency and lifetime. The comparison highlights that the LED provides good lifetime, however, for OLED it depends on the organic semiconducting materials responsible for emission. Different layers such as charge injection layers, transport layers and blocking layer to refine the properties of organic LEDs are also studied and compared. Addition to this, a low-cost methodology is also incorporated for the fabrication of flexible devices.

Published: July 2023

BACKGROUND:

The Mediterranean diet (MedDiet) has been linked with better cognitive function and brain integrity.

OBJECTIVE:

To examine the association of modified Mediterranean diet (mMedDiet) scores from early through middle adulthood in relation to volumetric and microstructural midlife MRI brain measures. Assess the association of mMedDiet and brain measures with four cognitive domains. If variables are correlated, determine if brain measures mediate the relationship between mMedDiet and cognition.

METHODS:

618 participants (mean age 25.4±3.5 at year 0) of the Coronary Artery Risk Development in Young Adults (CARDIA) study were included. Cumulative average mMedDiet scores were calculated by averaging scores from years 0, 7, and 20. MRI scans were obtained at years 25 and 30. General linear models were used to examine the association between mMedDiet and brain measures.

RESULTS:

Higher cumulative average mMedDiet scores were associated with better microstructural white matter (WM) integrity measured by fractional anisotropy (FA) at years 25 and 30 (all ptrend <0.05). Higher mMedDiet scores at year 7 were associated with higher WM FA at year 25 (β= 0.003, ptrend = 0.03). Higher mMedDiet scores at year 20 associated with higher WM FA at years 25 (β= 0.0005, ptrend = 0.002) and 30 (β= 0.0003, ptrend = 0.02). mMedDiet scores were not associated with brain volumes. Higher mMedDiet scores and WM FA were both correlated with better executive function, processing speed, and global cognition (all ptrend <0.05). WM FA did not mediate the association between mMedDiet scores and cognition.

CONCLUSIONS:

The work was carried out with the aim of disseminating the results obtained for producers in the reproductive sphere in the south of the state of Maranhão. Three rural properties with a semi-intensive production system were studied. Weight, age, race, Body Condition Score (BCS) and reproductive fitness response were collected. The evaluated animals had a weight greater than or equal to 280 kg/bw and aged over 12 months. The animals were divided according to age: group I- Animals between 12/24 months of age and group II- Animals between 24/36 months of age. The sexual maturity of the animal is totally linked with its age and weight.

Inbreeding and selection are forces that affect heritability, important to selection in livestock species. So, this study aims to relate those forces in a Holstein population under selection for superior milk production. Inbreeding coefficients was calculated considering 3 generations, after the individual inbreeding coefficient was calculated, inbred (7.92±2.72) and non-inbred group (0.46±0.38) were formed. The genetic variance was higher for the inbred group and for the residual variance was lower. As result, those variance changes resulted in higher heritability for all traits analyzed for the inbred group. For the levels of inbreeding observed in this study, the selection for higher productions possibly masked the effects of inbreeding.
Factors affecting dividend payment policy: Differences between consumer goods and consumer staples in Vietnam
Authors:   Ho Chi Minh City Open University, Vietnam, Nguyen Kim Phuoc
Published: July 2023

The factors affecting the dividend distribution policy of companies listed on the Ho Chi Minh Stock Exchange are investigated using the signal theory and agency cost theory (HOSE). To generate empirical evidence, the study collects data from publicly traded and dividend-paying consumer companies over a 12-year period (2009-2020). At the same time, in order to better understand the research problem, the study examines the variations in factors affecting the dividend payment policies of two kinds of consumer companies (consumer staples and consumer discretionary). The findings of the FGLS regression analysis demonstrate that the following factors always affect dividend payment policy, consumer services, and consumer goods companies: earnings per share, debt-to-equity ratio, form of cash, and stock dividend payment. Consumer staples and consumer discretionary corporations' dividend policies are influenced by distinct factors. Consumer products companies have a greater dividend payout ratio than that consumer service companies. The findings provide a scientific foundation for consumer service and consumer products companies to implement more appropriate dividend distribution policies and raise funds through the stock market.

Published: July 2023

Cross-border mergers and acquisitions transactions have increased dramatically around the world over the past several decades and have become one of the most important types of commercial transactions. In the process of performing cross-border mergers and acquisitions transactions, disputes will occur with certain characteristics at different stages. As a result, when a dispute occurs, the parties must use various dispute settlement methods such as negotiation, conciliation, court, arbitration. Combining the aforementioned ways is a prioritized choice for having an adequate mergers and acquisitions dispute resolution mechanism by leveraging the benefits while also eliminating the limitations of given methods. This article will analyze cross-border mergers and acquisitions disputes and some issues in dispute resolution by arbitration, such as joinder and consolidation procedure, expert participation and confidentiality in arbitration. Thereby, the Arbitration - Mediation - Arbitration (Arb-Med-Arb) model is proposed to be applied in resolving cross-border mergers and acquisitions disputes in Vietnam.

Climate change, mainly originating from CO2 emissions, has adverse impacts on the social-economic development of Vietnam. Forestation is one of the solutions to reduce CO2 emissions. Thus, this paper investigates the possible impact of reforestation on CO2 emissions in Vietnam during 1990-2019. Data in the study is collected from the World Bank. The study uses a Vector Auto Regression model (VAR) to analyze the relationship between reforestation and CO2 emissions. The research results show that forest coverage has a negative impact on CO2 emissions in Vietnam. On the other hand, the results also suggest that there is a two-way relationship between urbanization and CO2 emissions in Vietnam. Based on the findings, the Vietnamese government can reduce CO2 emission by increasing forest coverage, harmonizing between urbanization and economic growth toward green development and forest protection. This study is significant to the solutions of tackling climate change by providing evidence of the effects of reforestation on CO2 emissions in Vietnam.

The aim of this study is to explore the impact of Corporate Social Responsibility (CSR) activities in building customer trust and company reputation with limited resources in the Covid-19 pandemic context. Data was collected through questionnaires sent from August 2021 to November 2021 in major cities of Vietnam, then we evaluated hypotheses in the research model by using the SEM technique. The results show that CSR activities including four facets: economic responsibility, legal responsibility, ethical responsibility, and philanthropic responsibility have positive impacts on customer trust as well as influences directly and indirectly on corporate reputation. Simultaneously, three dimensions of trust including expertise trust, integrity trust, and social benevolence trust also have strong impacts on corporate reputation with different levels, therein social benevolence trust has the strongest impact on corporate reputation. Based on this finding, some management implications are also discussed to show how corporations can allocate appropriate resources for different CSR activities so that they could leverage the benefits from the CSR strategy in their business.

To enhance the smart Cloud Service System for diverse user requirements in 5G and other service networks, this study leverages resource utilization and multi-tenancy network slicing operation costs. Specifically, we propose a multi-tenancy network resource allocation strategy based on the Chaos Particle Swarm Optimization (CPSO) algorithm. In a multi-tenancy network (MTN), we lease the wireless spectrum resources of the infrastructure provider’s base station, construct access service slices as network slice services, and offer network access services to users. Introduce detailed formulation of the relationship between MTN and users, represented as a multi-master and multi-slave construct that defines the strategy space and profit function after MTN decision-making. Reverse induction is used to analyze the proposed model, and a distributed iterative algorithm is proposed to obtain the optimal throughput demand of users and the optimal slice cost of MTN. Simulation results demonstrate that the proposed strategy can effectively enhance resource utilization and user satisfaction while reducing energy consumption.
