The Function Of Information And Communication Technology In The Teaching And Learning Process During The COVID-19 Pandemic
Authors: Siahaan Chontina , Natonis Aprianer
Published: April 2022

This paper is intended to provide permanent information about learning in the era of the Covid-19 pandemic in utilizing information and communication technology. Based on the fact that most educators are not very familiar with managing information technology and communication and not all educational institutions feel the existence of technology that can support teaching and learning activities so that in the era of the Covid19 pandemic, there are still many schools that do the learning process manually, namely by providing modules or tasks to students to be done at home. This study was conducted using framing analysis of the phenomenon faced by teachers, especially teachers in Indonesia in an effort to improve competence in the era of the Covid-19 pandemic. The use of technology in the learning process can trigger increased interest and motivation for learning students until the quality of their learning increases. The use of gadgets that are commonly used by students in the present era in the teaching and learning process is expected to improve the quality of the teaching and learning process itself.

Abstract. Debris flows threaten communities in mountain regions worldwide. Combining modern photogrammetric processing with autonomous unmanned aerial vehicle (UAV) flights at sub-weekly intervals allows mapping of sediment dynamics in a debris flow catchment. This provides important information for sediment disposition that pre-conditions the catchment for debris flow occurrence. At the Illgraben debris-flow catchment in Switzerland, our autonomous UAV launched nearly 50 times in the snow-free periods in 2019–2021 with typical flight intervals of 2–4 days, producing 350–400 images every flight. The observed terrain-changes resulting from debris flows exhibit preferred locations of erosion and deposition, including memory effects as previously deposited material is preferentially removed during subsequent debris flows. Such data are critical for the validation of geomorphological process models. Given the remote terrain, the mapped short-term erosion and deposition structures are difficult to obtain with conventional measurements. The proposed method thus fills an observational gap, which ground-based monitoring and satellite based remote sensing cannot fill as a result of limited access, reaction time, spatial resolution, or involved costs.
Global coarse grained mesoscale eddy statistics based on integrated kinetic energy and enstrophy correlations
Authors: Jánosi Imre M. , Kantz Holger , Gallas Jason A. C. , Vincze Miklós
Published: April 2022

Abstract. Recently, Jánosi et al. introduced the concept of a “super vortex proxy” based on an observation of strong correlations between integrated kinetic energy and integrated enstrophy over a large enough surface area. When mesoscale vortices are assumed to exhibit a Gaussian shape, the two spatial integrals have particularly simple functional forms, and a ratio of them defines an effective radius of a “proxy vortex”. In the original work, the idea was tested over a restricted area in the Californian Current System. Here we extend the analysis to global scale by means of 25 years of AVISO altimetry data covering the (ice free) global ocean. The results are compared with a global vortex data base containing over 64 million of mesoscale eddies. We demonstrate that the proxy vortex representation of surface flow fields also works globally and provides a quick and reliable way to obtain coarse grained vortex statistics. Estimated mean eddy sizes (effective radii) are extracted in very good agreement with the data from the vortex census. Recorded eddy amplitudes are directly used to infer the part of kinetic energy transported by the mesoscale vortices. The ratio of total and eddy kinetic energies is somewhat higher than found in previous studies. The characteristic westward drift velocities are evaluated by a time lagged cross-correlation analysis of the kinetic energy fields. While zonal mean drift speeds are in good agreement with vortex trajectory evaluation in the latitude bands 30° S–5° S and 5° N–30° N, discrepancies are exhibited mostly at higher latitudes on both hemispheres. A plausible reason of somewhat different drift velocities obtained by eddy tracking and cross-correlation analysis is the fact that the drift of mesoscale eddies is only one component of the surface flow fields. Rossby wave activities, coherent currents, and other propagating features on the ocean surface apparently contribute to the zonal transport of kinetic energy.
TIGHTLY-COUPLED INTEGRATION OF BLE AND PDR USING GRAPH OPTIMIZATION FOR INDOOR PEDESTRIAN NAVIGATION
Authors: Wang X. , Zhuang Y. , Zhang Z. , Cao X. , Yang X.
Published: April 2022

Abstract. In this paper, we propose an indoor navigation method based on the tightly-coupled (TC) integration of Bluetooth low energy (BLE) and pedestrian dead reckoning (PDR) using a graph optimization model. We first utilize the Gaussian probability model to update the particle weights that considers the ranging model’s estimation performance at different distances to determine the particle weight. Moreover, the BLE walking-surveyed or crowdsourced landmarks, combined with accurate ranging of BLE at a short distance, is used to construct a graph optimization model, and the Levenberg-Marquardt (LM) algorithm is adopted to optimize this model to improve track tracking performance. The performance of the proposed algorithm has been verified in the hallway scene and another challenging room scene. The results show that compared with the standard particle filter (PF) method, the average positioning accuracy of the proposed algorithm is improved by 64.0% and 54.75%, and the error variance is significantly reduced by 76.23% and 68.60%, respectively, which is a significant improvement in both robustness and accuracy. Furthermore, the test shows that the proposed method can calculate reasonable trajectories even in complex room scenarios.

Modelo de Cartel a partir de uma indústria típica: um recorte da economia dos anos 70
Authors: Fontgalland Isabel Lausanne , Lima Lucas Vitor Andrade
Published: April 2022

Os cartéis são formas de preservação utilizadas pelas empresas dado um grande volume de informações imperfeitas e incertezas estabelecidas ao longo de várias manobras de mercado por entrantes ou firmas estabelecidas. As mais comuns são as de fixação de preços e definição do grau de oferta de produtos essenciais ou tecnológicos.  A fim de controlar as incertezas do mercado, e obter lucros de conluio (formados em reunião com empresas definidoras da demanda de bens), se prediz uma situação conhecida como empresas em cartel.  Um desafio, contudo, é posto para os cartéis empresariais qual seja o de como organizar atividades coletivas sem a utilização de controle legislativo, ou institucional, tais como contratos jurídicos vinculativos ou arbitragem através de agências reguladoras. Embora, se possa esperar que uma falta de controle legal conduza a conflitos mútuos e a comportamentos oportunistas, o cartel se forma como única alternativa de curta duração, para que as empresas possam sobreviver, numa situação de crise, pandemia ou conflitos de interesses no que diz respeito ao establishment social. Neste estudo, observa-se a predominância da organização em cartéis nos anos 70, dada a emergência das crises postas nas agências internacionais de controle do petróleo, OPEP e pela emergência da industrialização brasileira influenciada pela política do milagre econômico e desenvolvimentista dos governos desta época. Utilizou-se o método bibliográfico e exploratório, tendo por recorte temporal os anos 70. Os resultados descrevem a franca explosão deste tipo de conduta, o que reforçou o tipo de política industrial da época.

A Case for Capital Asset Consumption Accounting: The Demand for Local Public Goods in Ontario
Authors: Eden Ron
Published: April 2022

Public policies, including those with respect to make or buy decisions, estimates of the publicness and congestibility of local public goods, and of income and tax price elasticity are affected by the measure of expenditure of local governments. This paper presents the findings of an empirical study that supports the inclusion of asset consumption on the full accrual basis in the expenditure of local governments. The study estimates capital consumption using expenditure data for the period 1977 to 1988 for Ontario municipalities, a much longer time period than typically available for this type of study. The study contributes to the Accounting literature by providing theoretical and empirical support for accrual-based accounting for capital assets in a Not-for-Profit setting.

Published: April 2022

The present work aims to depict computationally efficient, model free, singularity free, generalized, non-iterative, single pass, and exact Link Folding (LF) Algorithm to tackle inverse kinematics (IK) problem. This paper presents a ‘single scan’ numerical algorithm conceived from geometric method to offer suitable IK solution for the robots coordinated and controlled by low resource controllers like Arduino Uno. This approach will reduce computational complexities of the methods like cyclic coordinate descending (CCD) algorithm and target triangle (TT) algorithm. An IK solution is guaranteed when the position to be reached is in robots’ workspace and for kinematic structures with unconstrained joints. The method does not require forward kinematics model which is being used in majority of the inverse kinematic solution methods. Test results are provided and analyzed to illustrate the performance improvements of the presented algorithm over the other geometric methods. For algorithm development MATLAB was used, verified in custom built simulator developed by authors, and validated with prototype built and controlled using Arduino.

Authors: Khemthong Suree , Charnkit Puripat
Published: April 2022

The aim of this study is to identify the influence of food attributes, perceived value, consumer trust and nutritional health behavior that contribute to consumer repurchase intention of foods with health claims. Descriptive Statistics was used to analyze the demographic profile of the 313 sample of respondents. Path analysis was conducted for analyzing the causal and effect relationship between variables expressed by means of a path coefficient. The results showed that there were only indirect effects between food attributes and Intention to repurchase. However, perceived value was shown to have both positive direct and indirect effects on intention to repurchase, which were significantly mediated by nutritional health behavior and consumer trust. Research results suggest food managers develop the value of food products and monitor the customer trust and the changes of market on the food with health claims for the competition in a current environment.
Determination of the natural disaster insurance premiums by considering the mitigation fund reserve decisions: An application of collective risk model
Authors: Sukono Sukono , Kalfin Kalfin , Riaman Riaman , Supian Sudradjat , Hidayat Yuyun , Saputra Jumadil , Mamat Mustafa
Published: April 2022

In Indonesia, natural disasters cases have significantly increased from time to time and have the largest impact on economic losses. To avoid losses in the future due to natural disasters, the insurance company needs to estimate the risk and determine the rate of premium that would be charged to the policyholder. In conjunction with the present issue, this study seeks to determine the premium rate and estimate the size claim of insurance by considering the mitigation fund reserve decisions using The Collective Risk Model (CRM). The data was analyzed using the Poisson process with Weibull distribution to determine the natural disaster frequency and losses. The distribution of losses is estimated using Maximum Likelihood Estimation (MLE), and the magnitude of losses was estimated using the CRM. Also, the mean and variance estimators of the aggregate risk were used to estimate the premium charged. The results indicated that expectation and variance of the frequency of incident claims have the same value, i.e., 2562. Also, the loss claims follow the Weibull distribution with the expected value and variance of 5.81309×1010 and 2.5301×1022, respectively. The mean and variance of the aggregate (collective) claims are 148,931,365,800,000 and 7.35×1025, respectively. In conclusion, this study has successfully determined the efficient pure premium model through the Standard Deviation Principle (SDP). SDP provides a much cheaper premium than the Expected Value Principle with the same loading factor. In addition, SDP considers the standard deviation of the collective risk of natural disasters. The implications of the results of the premium determination are expected to be the basis for decision-making for insurance companies and the government in determining insurance policies for natural disaster mitigation.

Published: April 2022

In order to identify the determinants that influence the credit risk of Peruvian municipal savings banks, this quantitative research uses a nonexperimental design and a longitudinal sample to analyze monthly data corresponding to macroeconomic variables and microfinance institutions’ internal variables from 2011 to 2020. Using multiple linear regression, the results show that the interest rate, unemployment rate, and liquidity ratio positively influence the credit risk of Peruvian municipal savings banks; the study also shows that gross domestic product, efficiency of administrative expenses, solvency, and coverage of provisions exert a negative influence on credit risk. It is concluded that seven of the eight independent variables studied influence the credit risk of Peruvian municipal savings banks; only the inflation variable does not significantly influence credit risk.
A hybrid matheuristic approach for the vehicle routing problem with three-dimensional loading constraints
Authors: Rodríguez Diego Alejandro Acosta , Martínez David Álvarez , Escobar John Willmer
Published: May 2022

This paper proposes a matheuristic algorithm based on a column generation structure for the capacitated vehicle routing problem with three-dimensional loading constraints (3L–CVRP). In the column generation approach, the master problem is responsible for managing the selection of best-set routes. In contrast, the slave problem is responsible for solving a shorter restricted route problem (CSP, Constrained Shortest Path) for generating columns (feasible routes). The CSP is not necessarily solved to optimality. In addition, a greedy randomized adaptive search procedure (GRASP) algorithm is used to verify the packing constraints. The master problem begins with a set of feasible routes obtained through a multi-start randomized constructive algorithm (MSRCA) heuristic for the multi-container loading problem (3D–BPP, three-dimensional bin packing problem). The MSRCA consists of finding valid routes considering the customers' best packing (packing first-route second). The efficiency of the proposed approach has been validated by a set of benchmark instances from the literature. The results show the efficiency of the proposed approach and conclude that the slave problem is too complex and computationally expensive to solve through a MIP.
Search for ways to improve the effectiveness of treatment of pulmonary tuberculosis patients with multiple resistance of mycobacterium tuberculosis to anti-tuberculosis drugs
Authors: Abdurakhimov A. A.
Published: April 2022

Aim. To conduct a comparative study of the effectiveness of treatment of MDR-TB patients by using short-term and individual chemotherapy regimens and including the drug Cholecalciferol in the treatment complex.

Material and methods. The group of MDR-TB patients with a short-term treatment regimen included 40 patients, and 40 patients were included in the group of MDR-TB patients with an individual treatment regimen. Both observation groups were divided into two subgroups of patients with MDR-TB of the lungs (20 people from each group). In one group treatment included Cholecalciferol 300,000 U intramuscularly weekly (6-8 times in total) in the complex of the above treatment; comparison groups: patients with MDR-TB of the lungs (20 people from each group) received a complex of the above chemotherapy without the drug Cholecalciferol.

Results. In the group of patients with the inclusion of Cholecalciferol in a short-term treatment regimen, a favorable treatment outcome was noted in 100% of cases, while in the group of patients without Cholicalciferol - in 80% of cases. With an individual treatment regimen in the group of patients with the inclusion of Cholecalciferol, conversion by sputum culture also occurred in 100% of cases, while in the group of patients without Cholicalciferol - in 70% of patients.

Conclusion. Thus, the introduction of a new short-term chemotherapy regimen for MDR-TB patients has increased the effectiveness of their treatment. In two subgroups of MDR-TB patients with different chemotherapy regimens, who received injections of Cholecalciferol in the chemotherapy treatment plan, the effectiveness of treatment based on the results of the timing of the development of conversion by sputum culture was assessed as significantly higher than in the subgroups that did not receive vitamin D3.

Published: April 2022

Aim. To conduct a clinical test of the unguent form of human leukocyte interferon in somatic patients with relapsing of herpetic stomatitis.

Material and methods. 98 somatic patients with viral pathology of the oral mucous at the age of 20 to 60 years and older were studied to identify the clinical efficiency of the leukocyte interferon. The order of the clinical studies was specified by a special program: preparations were decrypted, decryption was conducted after the analysis of the results of the clinical study. Preparation 1 – placebo (2% emulsion of lidocaine on vinilin), preparation 2 – interferon’s unguent, preparation 3 – 0.5% oxoline unguent. After active implementation of the complex treatment of patients with mucologic pathology were divided into 3 groups: 1st group included 31 patients who got a course of the treatment by preparation 1; 2nd - 34 persons, 2 have taken preparation; 3rd - 33 patients, 3 used preparation.

Results. The most expressed clinical effect in the treatment of relapsing of herpetic stomatitis in somatic patients with combined dentistry pathology was shown by preparation 2, which had local anesthetic and anti-inflammation action. Indicators of the recovery of patients who got this preparation in contrast with patients of the third group decreased on average by 2 days, the 1st groups - by more than 1 day.

Conclusion. Using oxolin’s unguent and preparation 1 in course of the treatment of herpetic stomatitis did not prevent the development of secondary elements in the oral mucous (24.0% and 44.0% accordingly) in most of the patients. Using preparation 2, new elements on oral mucous were observed only in 6.0% of cases, which shows it good antiviral effect.

Authors: Faizulloev A. I.
Published: April 2022

Aim. To present clinical and functional characteristics of chronic heart failure in association with diabetes mellitus type 2.

Material and methods. 105 patients with a verified diagnosis of chronic heart failure in association with diabetes mellitus type 2 who were hospitalized at the cardiology department of State Institution “RCRC” of Ministry of Health and Social Welfare of RT during the period 01.09.2020 - 01.08.2021 were examined. Of them, men were 48 (45.7%), women 57 (54.3%). All patients underwent general clinical, laboratory, instrumental, as well as functional examinations.

Results and discussion. Complex evaluation of patients with chronic heart failure in association with diabetes mellitus type 2 (n=105) showed that the majority of patients (96,2%) had metabolic subcompensation of carbohydrate metabolism - HbA1c>7%. The results of assessing the severity of clinical symptoms according to the clinical evaluation scale, indicators of renal function, and hemodynamic parameters of the heart in the group of patients with chronic heart failure in association with type 2 diabetes mellitus with arterial hypertension + coronary heart disease were significantly different from the group of patients with chronic heart failure in association with type 2 diabetes mellitus also with arterial hypertension and chronic heart failure in association with coronary heart disease.

Conclusion. The etiology of chronic heart failure in our study group is CHD and arterial hypertension, which have distinctive features depending on gender and age. The degree of clinical symptomatology manifestation is directly dependent on the functional class of chronic heart failure. The most frequent companions of chronic heart failure in association with type 2 diabetes mellitus are obesity and chronic kidney disease. Left ventricular hypertrophy is considered to be one of the unfavorable predictors of cardiovascular complications, and its fluctuations were observed in our patients.

Kết quả nghiên cứu: (i) Thuế Thu nhập Doanh nghiệp cao liên quan đến vốn vay sẽ làm giảm giá trị công ty; và thuế Thu nhập cá nhân thấp thì chính sách cổ tức cao-lợi nhuận giữ lại thấp khi đó công ty sẽ đi vay và giá trị công ty tăng; (ii) Quyết định tài trợ vốn vay và chính sách cổ tức của các công ty niêm yết trên HOSE không ổn định trong giai đoạn nghiên cứu. Điểm mới của nghiên cứu này so với các nghiên cứu trước ở Việt Nam là áp dụng mô hình của Fama-French (1998) để phân tích một cách gián tiếp tác động của chính sách thuế thuế thu nhập doanh nghiệp và thuế thu nhập cá nhân đến quyết định tài trợ thông qua giá trị của các công ty Việt Nam niêm yết trên HOSE.
Risk Culture and Strategic Planning Roles on Enterprise Risk Management and Firm Performance in Selected African Countries
Authors: Kanu Mohamed Santigie
Published: April 2022

Enterprise risk management (ERM) research has mostly been limited to factors determining its implementation and its effects on firm performance. Despite a clear need for its establishment in sound risk culture and its integration with strategic planning, organisational leaders continue to implement these management concepts in isolation. Academic research into these conjoint relationships has also received less attention in the literature. This study investigates whether ERM's effect on firm financial performance, measured by return on assets, is mediated by risk culture and strategic planning. The study provides empirical evidence that adopting ERM solely does not enhance a firm's financial performance. The ERM, risk culture, and strategic planning constructs are empirically determined to be correlated. Strategic planning has a direct and positive relationship with firm performance. The study further provides empirical evidence that the positive effects of ERM implementation on firm financial performance are mediated by risk culture and strategic planning. The size of a firm and its financial leverage are remarkable determinants of firm performance, while firm age and growth rate are not. The pieces of evidence have been presented from an under-investigated context in Africa with other contributions to the literature, such as, providing comprehensive measures of ERM and risk culture and responding to calls to synthesise risk and strategic management. This study also advances multiple mediation analysis and the use of PLS-SEM in the ERM literature.

Published: April 2022

The present study was conducted to test the theory of ‘the younger the better’ (Lenneberg, 1967; Penfield, 1959) by examining Tunisian EFL public primary school teachers’ perceptions of lowering the age of teaching English in elementary schools. In doing so, a quantitative method approach was used to collect data from a sample of 30 teachers working at public primary schools in Tunis and an interview for 5 inspectors of English from different regions of Tunis. They were asked to express their views concerning lowering the age of teaching English and the ability of children to learn more than one foreign language in academic situations. The purpose of this study is to to investigate the influence of age on language learning in Tunisian public educational system focusing on children’s ability to learn English effortlessly at a younger age.The data analysis revealed that a considerable percentage of Tunisian primary school teachers in the schools visited claim to be aware of the importance of lowering the age of teaching English and of the crucial role that English plays in the curriculum as well as the ability of children to learn foreign language with great enthusiasm. However, this awareness is not met by major efforts toward educational reforms by the ministry of education. Another finding of this research was that all the respondent teachers agreed on the best age for children to learn English in academic situations yet they disagreed with the fact that it is impossible to achieve proficiency in second languages in the second decade of life.This study provides evidence that English is important in Tunisian schools and teachers as well as policy makers perceive that lowering the age of teaching English provides longer exposure to the target language and is advantageous for children starting L2s at a younger age. Obviously, the age of teaching English in public schools is gaining importance, which suggests that it is going to be an influencing factor in any future educational reforms in public Tunisian schools.

Caracterizada como uma doença inflamatória, progressiva e neurodegenerativa com caráter desmielinizante, e frequentemente incapacitante do sistema nervoso central, a esclerose múltipla afeta cerca de 40 mil pessoas no Brasil e aproximadamente 2,8 milhões de pessoas no mundo. Dentre a gama de sintomas, problemas com a mobilidade, os quais, podem se manifestar já no início da doença, são bastante frequentes na esclerose múltipla. O presente capítulo tem por objetivo listar e descrever importantes testes de performance funcional (i.e., mobilidade) recomendados para pessoas com esclerose múltipla, que são utilizados para monitoramento da progressão e nível de incapacidade da doença. Tais testes são também recomendados em pesquisas envolvendo intervenções com exercício físico nessa população. No total, descrevemos seis testes, os quais focam na mobilidade funcional (Timed Up and Go), velocidade rápida do caminhar (Timed 25-foot Walk), capacidade de trabalho e fatigabilidade (Teste de Caminhada de 6 Minutos), função de membros inferiores (Short Physical Performance Battery), equilíbrio dinâmico e coordenação (Four Square Step Test) e, coordenação de membros inferiores (Six-Spot Step Test).
