Background and Aims The COVID-19 virus is a large group of viruses identified as a public health crisis and has challenged people worldwide. The epidemic of respiratory infectious disease and quarantine, limitations, stress, and other effects of this disease have affected the health, mental well-being, and emotional adjustment of all age groups. This study aimed to investigate the effect of sport on the health and emotional adjustment of students of universities in Qazvin province during the COVID-19 virus pandemic. Methods This research method was applied, presented, and described in this area. The statistical population included students of Qazvin province who, according to Cochran’s formula, 382 students participated in this study by cluster sampling. The research tools included demographic questions and the Bell Adjustment Inventory questionnaire, which used two dimensions of Emotional and Health Adjustment with acceptable reliability. Data were analyzed in descriptive and inferential statistics sections, and the Kolmogorov-Smirnov test, t-test, two independent samples, and Leuven test were used. Results The t-test of two independent samples and Leuven showed that sport significantly affected students’ health adjustment (P≤0.05). Regarding the variable of emotional adjustment, it was found that sports activities significantly affect the emotional adjustment of the statistical population (P≤0.05). The means of both health and emotional adjustment variables for the two groups (with and without sports history) were significantly different, and this difference was statistically significant (P≤0.05). Conclusion The results showed that sport improved the emotional and health adjustment of the students studied in this research. In other words, people with a history of sport could use more adaptive methods to deal with the problems caused by the CPVID-19 pandemic because sport contributes to physical and mental health. Thus, universities can use the benefits of promoting sport and physical activities to improve the adjustment of their students at different times as well as very new, unknown, and even exhausting crises or situations.

Background and Aims The risk of falling in people increases with aging. Aquatic exercises create a secure environment for people, and they can reduce the risk of falling among elderly people. This study aimed to investigate the effect of 8 weeks of aquatic exercises on postural control and balance recovery strategies. Methods Thirty elderly people from Kerman province were selected to participate in the research, and they were randomly divided into control (Mean±SD age 63.67±2.58 years, height 169.27±4.74 cm, and weight 71.00±6.95 kg) and intervention groups (Mean±SD age 65.00±3.07 years, height 169.50±27.34 cm, and weight 71.200±4.31 kg). The postural control and balance recovery strategies during sudden movement by treadmill were evaluated using the Biodex and motion analysis system. The intervention group participated in aquatic exercises for 8 weeks (3 times with 45 minutes per week) to challenge the physical and proprioceptive acuity, while the control group lived without any interventions. Data were analyzed using the ANCOVA and Pearson correlation tests (P<0.05). Results The results showed a significant improvement in the scores of postural control and balance recovery strategies (P<0.05). Balance strategies in elderly people moved from the hip toward the ankle (P<0.05). The onset time of muscle activity and the electrical activation of muscles in elders showed significant improvement after participating in this study (P<0.05). Conclusion The results approved that water training has significantly affected the ability to control posture and balance recovery strategies in the elderly and that changing the pattern of muscle activation has increased postural stability and improved balance. It recommends using these exercises in training programs for the elderly to decrease the risk of falls and improve balance.

Background and Aims The application of principles of motor learning in children with deficit/hyperactivity disorder (ADHD) is essential. This study investigated the effect of constant and variable practice on learning soccer pass skills in children with attention deficit hyperactivity disorder and normal children. Methods For this purpose, two groups of 34 ADHD and 34 typically developing children with a mean age of (8.36±0.51) were selected by purposive sampling. Each group was randomly divided into experimental (variable practice) and control (constant practice) subgroups. At first, the Pretest of the soccer pass was performed based on the Mor-Christian General Soccer Ability Skill Test Battery. Then the training program was conducted for 8 weeks consisting of two sessions per week (20 trials per session) for 45 minutes. After the last session, Post-test, and after one week, the retention and transfer tests were performed on two consecutive days. Data were analyzed using mixed-design ANOVA and one-way ANOVA. Results The results showed a significant within-group difference in all training groups from Pretest to Post-test (P=0.001). Comparison of Post-test, retention, and transfer tests in the training groups showed no significant difference between the training groups, but comparing the means indicates that in both groups of typically developing children and children with ADHD, variable training resulted in better retention and transfer than constant training. Conclusion In general, the results of this study showed that in children with ADHD, as in typically developing children, variable practice is probably more effective in the learning of soccer pass skills than constant practice.

Background and Aims The intelligibility context scale (ICS) is the first screening tool for the intelligibility of speech. The ICS assesses parents’ perceptions of their child’s speech clarity in real situations when talking with different people and has been adapted into more than 60 languages. The purpose of the current study was to evaluate the psychometric properties of the ICS-Persian in preschool Persian-speaking children. Methods This is a validation and instrumentation research study. The parents of 118 children aged 4 to 6 years with and without speech sound disorders (SSD) from 10 kindergartens in Isfahan were recruited to the study through a clustered randomized sampling method. A speech therapist evaluated all children to confirm their overall health. Their parents completed the ICS-Persian, and the Ages and Stages Questionnaire (ASQ) was completed for each child to determine the convergent validity of the ICS. In the test-retest study, 54 parents re-filled the ICS-Persian after 3 weeks. Statistical methods included Cronbach’s alpha coefficients, Pearson correlation, intraclass correlation coefficient (ICC), and paired t-test. Results Internal consistency and test-retest values were good and calculated as 0.89 and 0.82, respectively. The mean scores of children with and without SSD were statistically significant (P0.001). In addition, a significantly higher score obsereved in children who spoke similarly to their peers and children who did not talk identically on the ASQ, documenting good construct validity. Conclusion The ISC-Persian showed good psychometric properties for the population of persian-speaking preschool children. Iranian speech therapist can reliably use it with persian-speaking children for clinical and research purposes.

Background and Aims Genu valgus malalignment is associated with altered lower limb muscular activities during running. The study aimed to evaluate the effect of using a brace in three different knee flexion angles on the frequency of muscular activity during running in people with genu varus. Methods The statistical sample of this study consisted of 30 soccer students. Fifteen persons with genu varus and 15 healthy persons were selected to participate in this study. The electrical activity of the muscles, including medial gastrocnemius, tibialis anterior, vastus medialis, rectus femoris, vastus lateralis, biceps femoris, and semitendinosus, were recorded by electromyography system during running with four brace conditions (without a brace, knee brace at 15˚, 30˚, and 60˚ knee flexion). Results The results showed that the main effect of “brace” on the frequency spectrum of the biceps femoris during the loading phase was increased statistically. During the loading phase, the most significant median frequency of the biceps femoris was running with a brace with 30˚ knee flexion. The main effect of “brace” on the frequency spectrum of semitendinosus during the push-off phase was statistically significant. The lowest value of semitendinosus muscle was during running with a brace with 15˚ knee flexion. Conclusion The most significant effect of a knee flexor brace is on the frequency content of biceps femoris and semitendinosus muscles with a mount at 30˚ knee flexion. This may be due to the passive support role of the brace and possibly could prevent biceps femoris and semitendinosus injuries.

Background and Aims The study aimed to evaluate the effects of motion control shoes on knee joint co-contraction in overweight individuals with flat feet. Methods 15 overweight females with a navicular drop greater than 10 mm were selected with available sampling. Demographic characteristics of participants include Mean±SD age: 26.8±2.5 years, height: 1.7±0.1 m, weight: 82.5±3.2 kg, and Body Mass Index: 28.2±1.1 kg/m2. This study was done during running with both control (Supernova control, Adidas) and motion control (Supernovacushion, Adidas) shoes. An electromyography system recorded selected muscles’ electrical activity and then computed co-contraction values. Paired sample t-test was used for statistical analysis. Results Finding demonstrated that during the loading phase, the directed co-contraction of vastus medialis/lateral while using motion control shoes was greater than control shoes (P=0.035). Also, mediolateral-directed knee joint co-contraction while running with a motion control shoe was greater than the control shoe during the push-off phase (P=0.020). Conclusion Motion control shoes improved directed co-contraction in overweight individuals with flat feet, especially in the frontal plane that could modify imposed knee joint loads.

Published: August 2022

El Servicio Geológico Colombiano cuenta con la única Instalación licenciada para gestionar desechos y fuentes  radiactivas en desuso en el país: Instalación Centralizada  para la Gestión de Desechos Radiactivos (ICGDR). Entre las  prácticas de procesamiento de desechos radiactivos se encuentra el tratamiento previo y el acondicionamiento  como preparación para la disposición final; en ocasiones, se  reciben unidades de desecho que deben someterse a reducción de volumen y segregación para facilitar que lo  que vaya a permanecer en la zona controlada de  almacenamiento transitorio de la ICGDR esté constituido  exclusivamente por material radiactivo. En la actualidad,  dentro de las unidades almacenadas a la espera de su acondicionamiento, se destacan varios colimadores que  ocupan alrededor del 15 % de esta área y que contienen en  su mayoría material no radiactivo. Con el objetivo de  minimizar la ocupación de estos, y debido a la falta de un  procedimiento para su procesamiento, se propone elaborar  un protocolo para la reducción de volumen de unidades de  desecho de este tipo, que incluye una guía para la  segregación a través del desensamblaje y retiro de las  piezas radiactivas. La identificación experimental de las  partes de uranio empobrecido (U-238) fue posible a través  de la implementación de técnicas in situ y portátiles: espectrometría de rayos gamma de alta resolución y  fluorescencia de rayos X. Gracias a esta metodología, se determinaron las piezas y características del material radiactivo que conformaban el colimador, y representaban un 10 % del volumen de la  unidad de desecho inicial, y así proceder a su  acondicionamiento y almacenamiento temporal. Por su parte, el armazón restante fue dispuesto fuera de la ICGDR  como material aprovechable o residuo peligroso, de  acuerdo con las características de peligrosidad de cada  parte segregada.

Impact of Cloud-based Infrastructure on Telecom Managed Services Models
Authors: Anicho Ogbonnaya , Tariq Abdullah
Published: August 2022

This paper examines how cloud-based infrastructure is impacting classical implementations of telecom Managed Services (MS) models with focus on network operations and maintenance (O&M). The migration of legacy network assets to the ‘cloud’ has altered traditional telecom network configuration. This work explores how cloud-based network infrastructure may alter MS models in the telecom network domain. It is expected that the unique offerings of cloud-based solutions will impact existing MS models and may require redesigning or adjusting operation and maintenance processes and frameworks. As network infrastructure migrates to the cloud, telecom MS delivery models must evolve as well to satisfy new requirements. This paper lays out essential aspects of traditional MS models that may be impacted as a result of cloud-based infrastructure. It further proposes a framework, and conceptual software design for systematically analysing the gaps in current MS models in order to identify requirements for improved MS delivery in the cloud era.

Indonesia is currently experiencing its fourth industrial revolution in the 21st century. With the introduction of the internet, Indonesia is expected to gain more than a hundred billion US Dollars and twenty-six million job openings by 2030. The rising usage of information technology prompts regulators to develop The Electronic Information Transaction Act to protect the populace from cybercrime. However, the law attracts numerous criticism due to its vague interpretation. This resulted in numerous arrests of innocents throughout Indonesia. Thus, the public is trying to voice their opinions on social media for the sake of preventing any more cases in the future. The usage of Latent Dirichlet Allocation could provide numerous benefits for this research. The separation between latent topics among random mixtures helps to identify the common ground and correlation between each post. These latent topics will be elaborated with a sample post to provide insights and expectations of the public towards the law.

Authors: Harry Patria
Published: August 2022

Petroleum investment decision remains subject to economic and financial research for decades. Due to capital intensive and higher risk on oil exploration, the investment decision has become more important than ever before.  This study aims to shed some light on this issue by conducting four machine learning algorithms to predict the decision applying the dataset from 2007-2019. This study includes the Decision Tree, Random Forest, Naïve Bayes, and Support Vector Machine. A comparative performance analysis is the illustrated using confusion matrix, Cohen’s Kappa value, and the accuracy of each model and Area under the ROC Curve. In this study, a machine learning approach was carried out on the oil exploration data. The findings demonstrate that Naïve Bayes has the most accurate performance for the classification (94.5%), followed by Decision Tree (92.9%), Random Forest (90.9%), and Support Vector Machine (89.6%). In practice, the selected Naïve Bayes model was applied to assess the decision using a new data test. The findings can diminish the subjective blindness and confirmation bias in the investment decision and bring about a reasonable and orderly exploration and development of petroleum reserves.

Authors: Chi Yeong Nain
Published: August 2022

The primary purpose of this study was to apply the nonlinear autoregressive neural network to model the long-term records of the monthly mean sea level from January 1978 to October 2020 at Grand Isle, Louisiana, as extracted from the National Oceanic and Atmospheric Administration Tides and Currents database. In this study, the empirical results revealed that the Bayesian Regularization algorithm was the best-suit training algorithm for its high regression R-value and low mean square error compared to the Levenberg-Marquardt and Scaled Conjugate Gradient algorithms for the nonlinear autoregressive neural network. Understanding past sea levels is important for the analysis of current and future sea level changes. In order to sustain these observations, research programs utilizing the existing data should be able to improve our understanding and significantly narrow our projections of ffuture sea-level changes.

Authors: Bagas Adhim , Supraptono Eko
Published: August 2022

Cases of sexual violence and harassment have recently occurred among the public. Many print and non-print media report on issues of sexual violence and harassment. The PPP case is an abuse of the relationship between women and men which harms one of the parties because they are harassed or degraded in dignity, either verbally or non-verbally. Semarang was the highest rank in cases of sexual violence in Central Java in 2018. The PPP case reporting mechanism requires victims to go to a service center. Many risks make victims reluctant to report the incident that occurred because they are embarrassed in society and afraid that perpetrators will intimidate them. This paper aims to develop an android-based application to summarize the reporting mechanism by reporting PPP incidents experienced by victims using gadgets. Several menus provided include reporting menu, counseling menu, article menu, and Robo menu to identify categories of forms of harassment based on user input. The application is developed by using a customized waterfall method. Several testing has been developed to evaluate the application, such as Blackbox testing (achieves 100%), usability testing (achieves 79%), and media content testing (achieves 85.45%).

The article is devoted to understanding the essence of fiscal policy by comparing it with budget and fiscal policies. After all, the lack of unity in scientific circles on the content of the above terms causes an insufficiently comprehensive approach in the scientific substantiation of domestic practice of formation and implementation of fiscal policy in Ukraine. The aim of the article is to clarify the semantics and content of the concept of "fiscal policy". To achieve this goal, the following research methods were used: analysis, synthesis, comparison, logical generalization. The article proves that the concepts of "fiscal policy" and "fiscal policy" are essentially synonymous. The incorrectness of the use of the term "fiscal policy" is substantiated. The semantics of fiscal policy as an integral part of financial policy, which: is carried out in the process of financial relations for the formation and use of the budget fund; is realized with the help of technology of achievement of target landmarks through performance of functions; provided through the budget process and the process of managing financial relations; identified with the use of functional-target approach The content of fiscal policy is studied through the prism of functional and target approaches. This allowed to reveal the essence of fiscal policy through the activities of the state on: 1) substantiation of the concept, identification of goals and definition of tasks outlining the methods of their solution in the field of formation and use of the budget fund; 2) practical implementation of measures to ensure the achievement of the goal of managing budgetary relations through the budget process. It is proposed to understand fiscal policy as an integral part of financial policy, which: is carried out in the process of financial relations for the formation and use of the budget fund; is realized with the help of technology of achievement of target landmarks through performance of functions; provided through the budget process and the process of managing financial relations; identified using a functional-target approach. The expediency of further research in focusing on the studied history of the formation and development of fiscal policy in terms of functional and targeted approaches is substantiated.

The article defines the essence of banking institutions and insurance companies as leading financial intermediaries in Ukraine, whose legal status is determined by special laws of Ukraine. Emphasis is placed on the new Law of Ukraine "On Insurance" adopted last year, which takes into account changes in the legal regulation of the insurance market associated with the creation of a mega-regulator in the form of the National Bank of Ukraine. It is shown that the specified normative legal acts of Ukraine provide for the possibility of creating banking groups and insurance groups. It is proven that the integration of banks and insurance companies is due to the following factors: methods of interaction – transfer of banking risks to the insurance company and active sale of insurance products in bank branches; functions – capitalization and risk hedging; forms of integration – merger and acquisition; agreement on joint sale of financial products, use of each other's financial services; sales methods – creation of joint products of banks and insurers (bancassurance). The factors of disintegration of banks and insurers are identified: limited captive interests, insufficient financial culture, lack of common standards, imperfect legislation on cooperation and interaction between banks and insurers, insufficient motivation of bank employees when selling insurance products. The contents of the special adopted normative acts of the National Bank of Ukraine, which stimulate the integration of banks and insurers, are summarized, including: Regulations on the organization of the risk management system in banks of Ukraine and banking groups, Regulations on the procedure for regulating the activities of banking groups. Ways to develop bancassurance in Ukraine are proposed: termination of martial law, the arrival of branches of European banks and insurers in Ukraine, an increase in the volume of sales of insurance protection through the mediation of the bank, a decrease in the cost of credit resources; strengthening the financial condition and status of banks and insurance companies, increasing their capital; improving the transparency and openness of the financial market.

The article analyzes the prerequisites for the formation of performance auditing. Its role in ensuring the efficiency of budget management is determined. It was revealed that the widespread use of performance audit in the world is associated with such factors as the expansion of the scope of governments, the activation of their role in socio-economic development, the increase in public spending and the scarcity of resources, the development of democratic institutions and the growth of public consciousness. Scientific approaches to the interpretation of the nature of performance auditing are considered. It was found that in developed countries, performance audits have long gone beyond the public sector, audit companies perform it for clients regardless of their ownership. At the same time, in Ukraine, performance audits are conducted only for the state organizations, enterprises and institutions and are practically not considered by audit companies or their clients as a promising direction. Domestic scientists also mostly consider it only for the budget sphere, which is due to the relevant requirements of Ukrainian legislation. The expediency of conducting performance audit for the private sector is substantiated. The performance audit principles, which belong to the «3E's» concept and are described in ISSAI – economy, efficiency and effectiveness – are characterized. The authors analyzed modern approaches to including the principles of environment, equity, ethics, economic welfare into the list of performance audit principles. The authors proposed and characterized the principles of expediency and evolution. It was determined that conducting performance audit can become a kind of tool for achieving the goals of sustainable development and at the same time help the enterprise to improve the results of its activities. Trends in the further development of performance auditing are revealed, which is proposed to be defined as a form of audit that aims to analyze and assess how economically, efficiently and effectively the entity uses its resources in accordance with the goals of sustainable development and ethical values.
