Taxes play an essential role in state funding. As something that is not profitable for the company, it usually encourages efforts to reduce taxes by doing a tax avoidance. This study aims to determine the effect of environmental uncertainty on tax avoidance and to determine the managerial ability to weaken the effect of environmental uncertainty on tax avoidance. This study using SPSS, 458 samples used in this study are manufacturing companies listed on the Indonesia Stock Exchange in the period 2016 – 2020. The results of this study indicate that environmental uncertainty affects tax avoidance and managerial ability strengthens the effect of environmental uncertainty on tax avoidance. The result may be due to the large influence of environmental uncertainty in the company so that the risks obtained are difficult for managers to overcome.
Reviewing the Role of Investment in the West Kalimantan Border
Authors: Rahim Dian Anggraeny
Published: May 2023

The development of border areas that is rampantly carried out by the government, in addition to reducing regional disparities, also improves regional economic performance as one of the efforts made by the government is through PMA (foreign direct investment) and PMDN (domestic investment). Furthermore, the role of this investment is evaluated to see the extent of its success in the area's economic performance. The study had two objectives; first, to know what variables affect the reduction of the poverty rate and increase in GDP per capita in the border area of West Kalimantan covering five districts, namely Sambas, Bengkayang, Sanggau, Sintang, and Kapuas Hulu. The independent variables used in this study are the realization of PMA and PMDN investment, the number of industries, and the absorption of labor in the industrial sector. Using secondary data for 2019-2021 and Panel Data Regression analysis, it can be seen that only employment in the industrial sector influences increasing GDP per capita and decreasing poverty rates. Meanwhile, the realization of PMA and PMDN investment, as well as the number of industries, did not significantly influence. The second objective of this study is to determine which investment is better based on the Forecasting Method. The Naive Method shows that PMDN investments have a smaller MSE value and a lower MAPE value than PMA investments. It means that PMDN investment is more feasible to be used as an option for future funding development in border areas.
Predictive Model to Identify College Students with High Dropout Rates
Authors: Hoyos Osorio Jhoan Keider , Daza Santacoloma Genaro
Published: May 2023

Decreasing student attrition rates is one of the main objectives of most higher education institutions. However, to achieve this goal, universities need to accurately identify and focus their efforts on students most likely to quit their studies before they graduate. This has given rise to a need to implement forecasting models to predict which students will eventually drop out. In this paper, we present an early warning system to automatically identify first-semester students at high risk of dropping out. The system is based on a machine learning model trained from historical data on first-semester students. The results show that the system can predict “at-risk” students with a sensitivity of 61.97%, which allows early intervention for those students, thereby reducing the student attrition rate.

Indonesia is a country that has the most energy sources in the Southeast of Asia and the fifth in Asia-Pacific subsequent to China, India, Japan and South Korea. Energy usage in Indonesia in 2016 was still dominated by 47% fuel oil. If the energy usage increases continuously, energy sustenance and resilience in Indonesia will be plagued. Therefore, there is a necessary to utilize the alternative energy sources that would be earth-friendly as well New and Renewable Energy (EBT) like bioethanol. Bioethanol can be produced by organic wastes, pseudostem of Musa Balbisiana (Pisang Klutuk) as the example. This research is focused on the study of delignification and adsorption of the process of bioethanol using pseudostem of Musa Balbisiana as the blending raw material to gasohol. The process started with the pre-treatment and delignification of the pseudostem of Musa Balbisiana with the sorts of NaOH concentration including the following of 10%, 20%, 30% and 100oC, 125oC, 150oC, 175oC, dan 200oC for the heating temperatures. In delignification, it can be stated that the concentration of 10% NaOH on 150oC temperature produced the finest cellulose and lignin content with the amount of 81,3% cellulose and 10,1% lignin. The pseudostem fibers that have passed the process of delignification, was done to the process of hydrolysis and fermentation for producing bioethanol. The result of Bioethanol was carried out to the process of distillation for separating bioethanol and water. Continuing the process, bioethanol was purified in adsorption and distillation process. In adsorption, the 5gr, 10gr, 15gr, 20gr, and 25gr adsorbent alloyed to the purified bioethanol, and it can be claimed that the highest rate of purified bioethanol is 20gr with the 99,11% bioethanol content. The 99,11% bioethanol content was blending with Pertalite with the ratios of 5:95, 10:90, 15:85, 20:80, and 25:75, thereafter it was analyzed the RON content which obtained the highest point that is 97,48 on 25:75 ratio.

Function and Role of Ancient Japanese Doctors
Authors:   The Korean Association For Japanese History, Chung Ki-Ung
Published: May 2023

In this paper, the role of doctors who worked in ancient Japan was examined in detail by dividing them into domestic and overseas. First of all, the Tengyoryo doctor was in charge of the treatment and examination of the imperial family and management, and was dispatched to Daigakuryo and Kuraryo. In addition, doctors were installed in departments that escorted the emperor or defended the palace, and strategic points such as Dazaifu and Tsushima. In addition, doctors were trained in the provinces to treat the people affected by the epidemic. Looking at this, it can be seen that domestic doctors faithfully performed the role of “examining and treating all diseases” as stipulated in the Ritsuryo.
Subsequently, Engishiki lists the combination drugs and herbal medicines paid to the envoys, and the doctors in the envoys judged that they would have used these drugs to treat other envoys who were sick. Doctors dispatched to Bokkai took a lot of medicine compared to doctors dispatched to Tang and Silla because the voyage between Japan and Bokkai was so rough. And it could be seen that it was the doctor's main job to treat a group of envoys suffering from various diseases caused by a rough voyage. And it was found that the doctor's medical skills at the time were very excellent in that even highly toxic herbicides were used.
In conclusion, ancient Japanese doctors were very active in various ways, not only in the central government and provinces but also abroad, and were very actively engaged in treatment.

Authors: Massó Salazar Lenin , Oquendo Llorente Vilma , Muñoz Alfonso Marta Elena
Published: May 2023

La violencia escolar en el contexto de la educación inclusiva constituye una problemática con limitado tratamiento teórico-metodológico en la pedagogía actual. En los últimos años han destacado los estudios teóricos sobre la violencia escolar, que apuntan a visibilizar las manifestaciones entre los miembros de la comunidad educativa desde una perspectiva unilateral. Constituye objeto de análisis de este estudio el incremento de las investigaciones teóricas acerca de las insuficiencias del proceso de inclusión en el contexto educativo y su relación con la violencia escolar como fenómeno que genera exclusión, en particular de los educandos con trastornos de conducta; asimismo, se revisa la participación de la comunidad educativa en esta dinámica. En este sentido, se analizan los nexos teóricos y prácticos entre violencia escolar y las insuficiencias en el proceso de educación inclusiva en contextos con educandos con trastornos de conducta. Se toman como referentes los estudios teóricos de Galtung (2003) que permiten abordar la problemática desde su complejidad y se complementan con los resultados de investigaciones realizadas con miembros de la comunidad educativa que participan en la atención a los trastornos de conducta.

Published: May 2023

Objetivo: Analisar os benefícios do uso de ômega 3 na melhoria clínica e melhoria cognitiva da pessoa com Alzheimer. Métodos: Foi realizada uma Revisão Integrativa da Literatura (RIL), sendo formulada a pergunta norteadora da pesquisa. Posteriormente, os Descritores em Ciência da Saúde (DeCS), “suplementação”, “ômega 3” e “Doença de Alzheimer” foram cruzados nas seguintes bases de dados: SCIELO, PUBMED e LILACS, com o operador boleano ´´AND``, utilizando critérios de inclusão e exclusão para seleção dos artigos. Resultados: Os estudos mostraram evidências que corroboram com a prerrogativa de que a suplementação com ômega 3 tem efeitos benéficos para função cognitiva de pessoas com comprometimento cognitivo leve ou até mesmo de leve a moderado, sobretudo quando tal suplementação é feita em estágios inicias de declínio cognitivo. No entanto, há trabalhos científicos que relatam a necessidade de estudos mais prolongados, com maior amostra e padronização da dose de Ácido Docosahexaenóico (DHA) e Ácido Eicosapentaenóico (EPA) aos participantes. Considerações finais: Considera-se, portanto, que a suplementação com ômega 3 melhora a função cognitiva do paciente com DA e até mesmo auxiliam na prevenção do Alzheimer. Contudo, há necessidade de estudos mais prolongados e com amostra maior e com padronização da suplementação do ômega 3.

Pathophysiological and Diagnostic Aspects of Sarcopenia in Hemodialysis Patients
Authors: Sitaš Zvonimir , Mihaljević Dubravka
Published: May 2023

Chronic kidney disease and renal replacement therapy, particularly hemodialysis, contribute to the development of negative protein balance and muscle dysfunction in dialysis patients, from the development of protein-energy malnutrition to sarcopenia. Due to multifactorial etiology and complex pathophysiological patterns, sarcopenia has proven to be a significant predictor of cardiovascular events and is associated with a higher risk of overall mortality. Screening methods of chronic kidney patients and patients on hemodialysis who are at higher risk of developing sarcopenia, as well as diagnostic methods for this group of patients are not clearly defined, hence methods used for the general population of elderly patients, especially based on the revised European consensus on definition and diagnosis of sarcopenia of the European Working Group on Sarcopenia in Older People (EWGSOP2), are utilized in this subpopulation as well. Therefore, there is a need to define new biomarkers of sarcopenia such as the existing 24h urine excretion of creatinine, a product of estimated glomerular filtration of cystatin C and creatinine or myostatin and their use in routine work with dialysis patients to identify this condition among them and reduce morbidity and mortality.

Lockdown measures to control disease transmission were implemented at the start of the COVID-19 era, worsening the already existing sedentary lifestyle. Reduced physical activity (PA) and unhealthy eating habits have a negative impact on mental health in chronically ill patients, including diabetes patients. Mental illness, on the other hand, encourages a sedentary lifestyle, exacerbating all components of metabolic syndrome. While well-controlled diabetic patients with an HbA1c of less than 7% had a less severe clinical presentation and COVID-19 mortality rates, the favorable effect of PA on immunomodulation and immunoregulation should not be neglected. Given recent data indicating that a sedentary lifestyle is the third independent risk factor for COVID-19 complications and death (after advanced age and organ transplant), including regular PA has never been more vital. Since PA has a major impact on both glycemic control and mental health, implementing structured home-based activity programs could improve glycemic control and psychological well-being, hence positively impacting COVID-19 outcomes.
Computer Vision Solutions for Range of Motion Assessment
Authors: Aleksić Jelena
Published: May 2023

Joint range of motion (ROM) is an important indicator of physical functionality and musculoskeletal health. In sports, athletes require adequate levels of joint mobility to minimize the risk of injuries and maximize performance, while in rehabilitation, restoring joint ROM is essential for faster recovery and improved physical function. Traditional methods for measuring ROM include goniometry, inclinometry and visual estimation; all of which are limited in accuracy due to the subjective nature of the assessment. With the rapid development of technology, new systems based on computer vision are continuously introduced as a possible solution for more objective and accurate measurements of the range of motion. Therefore, this article aimed to evaluate novel computer vision-based systems based on their accuracy and practical applicability for a range of motion assessment. The review covers a variety of systems, including motion-capture systems (2D and 3D cameras), RGB-Depth cameras, commercial software systems and smartphone apps. Furthermore, this article also highlights the potential limitations of these systems and explores their potential future applications in sports and rehabilitation.

The emergence of life remains one of the most intriguing scientific questions, and understanding the chemical processes that led to it is essential. Recent discoveries of C3H2NO isomers in the interstellar medium have motivated further exploration of this molecular formula. Here, we use density functional theory to explore the potential energy surface of C3H2NO isomers, including acyclic and cyclic structures, and identify twelve low-lying isomers. We then investigate bimolecular reaction with HCN and H2CO using an artificial force-induced automated search and transition state search for the minimal energy routes. Our results predict the formation of Oxiran- 2-ylazanide and (Z)2-aminoacetaldehyde as the kinetically and thermodynamically controlled products, respectively. These results provide insights into the potential formation of biomarkers such as N-methyleneformamide in the interstellar medium, which have been found in recent years. Our study contributes to prebiotic chemistry and offers a critical step toward understanding the chemical processes that led to the emergence of life in the universe.

Published: May 2023

This study analyses locus equations and regression lines relating to second and third formants as a measure of co-articulatory influence of vowels following stop consonants in EkeGusii. Coarticulation can be represented statistically using a schematic representation of locus equations by tracking consonant-vowel (CV) transition as a useful tool in the discrimination of place of articulation. Acoustic data was collected using Praat version 6.0 from four males and four females, native speakers of EkeGusii. Locus equations for the eight speakers were derived from CV words with intervocalic voiceless bilabial /p/, voiceless alveolar /t/ and voiceless velar /k/ preceding vowel /i/, /a/ and /o/ contexts. Scatter plots of locus equation of F2 and F3 onsets-F2 and F3 midpoints revealed patterns for each of the three voiceless stops in EkeGusii. The strongest degree of coarticulation is reported for velars then bilabials and the least degree of coarticulation with alveolars.

ABSTRACT. Worldwide, there are about 466 million people (6.1%) with hearing loss and approximately 34 million of them (7%) are children, two-thirds of whom live in developing countries. In the course of research, it has been proven that in 60% of cases, sensorineural deafness is combined with vestibular disorders, which can be both obvious (rarely in children) and hidden. Timely detection of vestibular disorders in young children, especially hidden ones, prevents delay in the child’s motor development and significantly reduces the risk of vestibular dizziness development in older age. The aim of the article was to study modern instrumental methods of balance function research in children based on scientific analysis of contemporary literary data. Materials and methods: A comprehensive search of relevant literature sources was conducted in December 2021 using electronic databases RubMed, EMBASE, MEDLINE, U.S. National Library of Medicine Clinical Trials, Research Gate and Cocharane Library. The results: Despite highly developed technological diagnostic capabilities of present-day medicine, the study of etiology, prevention and correction of various balance and hearing disorders in children of different ages is one of the most acute issues to be solved by modern medical community. Up-to-date improvements in the diagnostic methods of the auditory and vestibular analyzer expand the possibilities of interpreting their results and allow a deeper understanding of the degree of the stato-acoustic analyzer damage. To investigate the vestibular function, vestibulometry and otoneurological examinations are usually carried out, which are the same tests that are used in adults. However, such examinations require more patience from the child and they should be conducted in a playful manner. Detection of hidden vestibular dysfunctions ought to be comprehensive, in particular, using instrumental methods, one of which is static computer stabilometry, that creates an opportunity to determine translational and motor disorders. The conclusion. Long-term problems with balance in children can lead to a delay of motor functions development, which can further slow down the child's achievement of age-appropriate psychomotor stages and have a negative impact on school performance, and in general, on social, speech and intellectual development. Therefore, detection of vestibular dysfunction at an early age is of great medical and social importance. Acute otitis media is currently a curable disease in most cases, if undesirable consequences are prevented during the period of examination and treatment. Vestibular function can be adequately assessed using reliable instrumental tests. In this sense, static stabilometry is a very useful method for the objective determination of vestibular deficits in children, regardless of the presence or absence of any subjective complaints.
Estimation of dependable flow in river baspa at kuppa barrage using flow duration curve
Authors: Vivekanandan N.
Published: May 2023

Estimation of dependable flow at different levels is considered one of the important parameters for planning, designing, and managing water-related projects, including hydropower generation, irrigation systems, water use, and river and reservoir sedimentation. For this purpose, the Flow Duration Curve (FDC) is developed by analyzing the available stream flow data at the site when adequate length of observed data are not available. The FDC is a valuable tool for determining the flow patterns of a river and estimating dependable flow. The FDC provides the percentage of time duration during which a stream flow (monthly, seasonal, or annual) is exceeded over a recorded period for a particular river or stream, which can be constructed by adopting the empirical method. By analyzing the FDC, the flow patterns of the Baspa river at the Kuppa barrage were determined, and the dependable flow was estimated. This paper presents a study on the assessment of monthly, seasonal, and annual dependable flow through the FDC by adopting an empirical method for the river Baspa at Kuppa barrage. The study suggests the dependable flow at different percentage levels like 75%, 90%, and 100% obtained from FDCs could be used for planning irrigation, hydropower, and drinking water projects in the study area.
