Published: July 2022

One impact of the COVID-19 pandemic on education is the mandated learning from home or distance learning (DL) in both state and private education institutions to prevent the transmission of COVID-19. DL may require long periods of time in front of a computer screen, which can create ergonomic issues such as eye, shoulder or neck problems, low back pain, and fatigue or stress. This study was structured to look at the ergonomic behavior of students in the statistics department at Padjadjaran University. The data were gathered using questionnaire, and there were 146 respondents who were willing to answer and send back the questionnaire. The results of the analysis show that the majority of students do not have knowledge about ergonomics when using computers. However, students agree that wrong posture can affect health conditions, especially those related to musculoskeletal disorders. The real impact felt by students is the health condition around their neck, shoulders, waist, bottoms, and wrists.

Authors: Nataliana Decy , Fauziah Dini , Dianti Mellynda Riska
Published: July 2022

In this study, a rakaat counter tool was designed and implemented to reduce mistakes in calculating the number of rakaat during prayer. The piezoelectric is used as sensor which is placed on the top of the prayer mat. Rakaat is calculated when piezoelectric has detected twice prostration. There are four modes in this system, namely fardhu prayer with seven segment display, fardhu prayer withÂ  LED display, sunnah prayer with seven segment display, and sunnah prayer withÂ  LED display.. There is an LED indicator when the rakaat is done which should be in accordance with the prayer time using RTC. The first test of this tool was carried out with piezoelectric calibration when pressed by the load and forehead. This was accomplished to determine when piezoelectric counting proceeded as piezoelectric was connected directly to the ADC of Arduino Uno. The second test was carried out by testing the tool to be used for 3 days in 5 fardhu prayers and 1 sunnah prayer. From the results of the testing it is proven that this tool works properly, and piezoelectric can be used as a replacement button as a tool for rakaat counter.

Published: July 2022

The COVID-19 pandemic condition has changed various aspects of life, especially Muslimsâ€™ prayer activities. COVID-19 pandemic has especially affected mosques as a place for Muslims to pray five times a day and to have Friday prayer congregation. To prevent the spread of COVID-19, the Sabilussalam Mosque located at Jl. Dr. Hatta Bandung has restricted its capacity and ensured visitorsâ€™ body temperature below 37,4 C manually. However, physical contact still occured, and its capacity still exceeded 50%. Therefore, the adoption of self-check temperature and automatic capacity counter as a method of mitigating the COVID-19 pandemic in mosques was needed. This community service aims at implementing a system for controlling mosque capacity and for avoiding physical contact during praying. The Low Code-based app counts temperature data broadcasted by K3 Pro and stored in NowDB cloud-service. As a result, the system manages to control the mosque's capacity to a maximum of 50% without any physical contact because it relies on internet connection.
Mechanical Properties of Eco-friendly Concrete Made with Sugarcane Bagasse Ash

Published: July 2022

Modern concretes lay emphasis on high strength in order to reduce structural member sizes to reduce materials used; high early strength to promote fast construction; high durability to reduce maintenance costs; and the incorporation of industrial and agricultural wastes to reduce environmental degradation. The incorporation of industrial and agricultural wastes into concrete as cement replacement materials reduces the amount of cement used in the production of concrete and the CO2emissions arising from cement production. Sugarcane bagasse is a waste product from the extraction of juice from sugar cane. It is estimated that 1.7 million tons of bagasse are produced worldwide every year. Much of the bagasse is used as boiler fuel and to produce electricity, and the ash is dumped in earth fills, resulting in critical environmental pollution that requires immediate attention. Available literature shows that when burned under controlled conditions, a pozzolanic ash of high silica content can be obtained, which can be used in concrete production with several advantages. This study investigates the mechanical properties of concrete designed for high strength and incorporating processed sugarcane bagasse ash in amounts of 10–40% by weight of cement in a binary combination with silica fume. Concrete workability in the fresh state and compressive, flexural, and tensile strengths in the hardened state are investigated. Water absorption of hardened concrete is also investigated as an indicator of potential durability. The results show that the mix containing 10% SCBA has the highest mechanical strength, and increasing the SCBA percentage reduces water absorption. However, the workability of concrete in the fresh state reduces substantially with an increase in ash content. Doi: 10.28991/CEJ-2022-08-06-010 Full Text: PDF

Published: July 2022

This experimental research aims to study the use of wire mesh–epoxy composite (WMEC) as a shear-strengthening technique for reinforced concrete (RC) beams by focusing on the following parameters: (1) presence of shear reinforcement in the shear span; (2) type of strengthening technique (U-jacketing, vertical U strip, or inclined strip); and (3) number of wire mesh layers (three or six layers). Nine simply supported rectangular RC beams were tested under two monotonic point loads. The testing specimens were divided into two groups: (1) five beams without shear reinforcement and (2) four beams with shear reinforcement. Load–deflection relationship, shear ductility index, beams’ stiffness, energy absorption, crack propagation, mode of failure, and strain were studied for all testing specimens and compared with those of the control beams to measure the improvement from WMEC addition. Results showed that all WMEC types enhanced the shear capacity. Among the three shear-strengthening types, the continuous U-jacket scheme had a higher effect, increasing the shear capacity between 33.4 and 95.9% and the shear ductility index by 23% relative to those of the reference specimens. The shear capacity improvement by WMEC for the beams without shear steel reinforcement was greater than that for the beams with shear reinforcement under the same shear-strengthening configuration. When the number of wire mesh layers was doubled, the ultimate load was further increased from 33.4 to 57.8%. This research showed that WMEC is a practical and excellent shear-strengthening technique for RC beams. Doi: 10.28991/CEJ-2022-08-06-09 Full Text: PDF

INFORMATION SIGNIFICANCE OF FINANCIAL ANALYSIS OF ECONOMIC SUBJECTS
Authors: Shnayder Viktor , Gerasimova Elena
Published: July 2022

The real result of the financial analysis of an economic entity directly depends on the accuracy and quality of the information used. Undoubtedly, the quality of the analysis cannot exceed the quality of the information used. That is why different types of information are used in the analysis. In some studies, the information used in the analysis is limited to financial information only. Along with financial information, when conducting financial analysis, production, technical, social, environmental and macroeconomic information is used, as well as conditional information is necessary when interpreting the results and developing development prospects. Limiting the analysis to financial information reduces the analytical potential of an economic entity for an objective assessment of its production potential, its opportunities for intensification and various trends in the sector in which this entity operates, as well as at the regional and national levels.

Published: July 2022

In the old days, most villages and towns of states and nations in Africa are founded with or through cowrie shells (owo eyo), thereby serving as evolutionary symbols and objects. There are several arts, cultures, traditions, heritages, and economic development (ACTHED) activities, cowrie shells (owo eyo) are being used in Nigeria and Africa generally, and Ojo-Alaworo town specifically, which is the target of this study. This ACTHED does not leave out socio-cultures, religion-magical and spiritual endowments. The aforementioned artistic activities are gradually facing out in our society through civilisation. Therefore, this study focuses on appraising and refreshing our memories of the significance and vital roles that cowrie shells (owo eyo) played and still play in the sojourn of the human race in Ojo-Alaworo town of Lagos State, Nigeria. In this regard, functionalism and symbolic interactionism theory of culture were used as a theoretical framework to analyze this study. As a qualitative research design, data were collected through semi-structured interviews (SSI) with five participants. They are indigenous elders (three males and two females) ages 70 to 85 years. The reason for this purposive sampling is that elders are wiser and more experienced in ACTHED, hence the Yoruba adage “iriri lagba”. The findings were discussed extensively which shows that cowrie shells (owo eyo) are inevitable in Ojo-Alaworo town despite civilisation in the town. To this end, a conclusion was made, and recommendations were suggested to revive the values of cowrie shells (owo eyo).

Published: July 2022

Due to the fact that the practice of online learning in Islamic elementary school students is considered ineffective, the government has issued a policy to implement face-to-face learning with limiting setting (PTMT) during the outbreak. This study aims to investigate the response of parents of students at MIN 1 Kolaka Utara regarding the implementation of such policy. This study employs a descriptive quantitative approach with 160 respondents who were selected purposively. Research data was collected through using an open questionnaire by google form. The result uncovered that 95% of the parents agreed that online learning was ineffective due to students easily getting bored studying at home, the difficulty of students to understand the material, and the eagerness of students to back to school. 3.1% of the parents were hesitant to such policy because of the existing of COVID-19 cases, the questionable PTMT, the doubtful compliance with health protocols, and lack of information about covid-19. And 1.9% of the parents disagreed with the policy because there are still cases of covid-19, PTMT was carried out in shifts setting, and most citizens are still unwilling to comply with health protocols. According to parent's response, the implementation of the PTMT has advantages such as the existing of interaction between students and teacher, the ease of understanding the material, and the high motivation of students to learn. However, PTMT has drawbacks. The implementation of class learning is still limited, the learning applies a shift system, students are still learning independently, and health protocols are not optimal to comply. In general, as much 49.3% of the parents considered the PTMT should be continued, 6.9% of them agreed on the PTMT should not be implemented, and (43.8%) suggested another method like blended learning to apply.

Background

High quality is a necessary feature of healthcare delivery. Healthcare quality challenges are particularly present in conditions of extreme adversity, such as conflict settings or sustained humanitarian crises. Digital health technologies have recently emerged as an innovation to deliver care around the world in a variety of settings. However, there is little insight into how digital health technologies can be used to improve the quality of care where extreme adversity introduces unique challenges. This study aimed to identify how digital health technologies may be most impactful in improving the quality of care and evaluate opportunities for accelerated and meaningful digital innovation in adverse settings.

Methods

A phenomenological approach (Interpretative Phenomenological Approach [IPA]), using semi-structured interviews, was adopted. Six individuals were interviewed in person based on their expertise in global health, international care delivery, and the application of digital health technologies to improve the quality of care in extreme adversity settings. The interviews were informed by a semi-structured topic guide with open-ended questions. The transcripts were compiled verbatim and were systematically examined by two authors, using the framework analysis method to extract themes and subthemes.

Results

The participants identified several areas in which digital health technologies could be most impactful, which include engagement in care, continuity of care, workforce operations, and data collection. Opportunities for accelerated digital innovation include improving terminology, identity, ownership, and interoperability, identifying priority areas for digital innovation, developing tailored solutions, coordination and standardisation, and sustainability and resilience.

Conclusions

These results suggest that there are conditions that favour or challenge the application of digital health technologies, even in specific areas in which they could be useful. A better understanding of the drivers and barriers to digitally driven quality improvement in settings of extreme adversity could inform international policies and optimisation strategies for the future.
The relationship between frontal QRS-T angle and premature ventricular contraction burden in ambulatory 24-hour Holter

Aim: Frequent premature ventricular contractions (PVCs) can cause impaired ventricular function or dilatation of ventricular cavities. The frontal plane QRS-T [f(QRS-T)] angle is an indicator of instability in the electrophysiological properties of the myocardium and is associated with arrhythmias. The present study aimed to investigate whether f(QRS-T) angle, as a marker of ventricular repolarization heterogeneity, predicts premature ventricular contraction burden in ambulatory 24-hour Holter.Methods: The study included 100 patients. The patients were divided into two groups as ‘frequent PVC’ and ‘seldom PVC’ according to their PVC burden in 24-hour Holter monitoring. Laboratory and some ambulatory electrocardiography parameters, including frontal plane QRS-T angle, were compared between the two groups.Results: Frontal QRS-T angle (63.34±37.86° vs 23.46±14.29° p<0.001) was found to be wider in the Frequent PVC group. F(QRS-T) angle of ≥ 34° had a sensitivity of 82.2% and a specificity of 80% in indicating PVC load (AUC: 0.887 (0.824-0.950). In addition, a positive correlation was found between PVC burden and f(QRS-T) angle (r:0.429 p<0.001).Conclusion: The widening of f(QRS-T) angle could perhaps be considered as a surrogate marker of increased PVC burden in 24-hour Holter monitoring. Measuring f(QRS-T) angle in 12-lead ECG in patients with PVC may be a warning sign for increased PVC burden.

Aim: This study aims to determine the effect of individual breastfeeding training on breastfeeding behaviors and traditional practices.Materials and Methods: The research was of randomized controlled design. The study was conducted at the family health centers in Kütahya, Turkey. A total of 304 mothers were recruited into the study, 152 in the intervention group and 152 in the control group. The Chi-Square Test, Mann-Whitney U Test and Kruskal-Wallis Test and Multinomial logistic regression were performed. Results: After the training, the rates of the mothers whose breastfeeding duration and frequency were sufficient, who breastfed their babies in the correct position, who did not have any breastfeeding problems, and whose babies latched onto the breast correctly were significantly higher in the training group than were the rates of the mothers in the control group (p<0.05). Conclusion: The individual breastfeeding training had an implication in improving breastfeeding behaviors and reduced harmful traditional practices.

Práticas culturais como o ajuste da densidade de semeadura da soja tem contribuído significativamente na prevenção e manejo de doenças foliares, por meio de alterações provocadas no crescimento de plantas, fechamento de entrelinhas e na taxa de penetração de agrotóxicos no dossel da cultura. Objetivou-se quantificar a severidade de doenças fúngicas foliares e o nível de desfolha ao longo do ciclo produtivo de cultivares de soja submetidas a densidades de semeadura. Para tal, foram utilizadas duas cultivares, dispostas em cinco densidades de semeadura. Durante o período reprodutivo da cultura, foram realizadas avaliações visuais, por meio da utilização de escalas diagramáticas propostas para quantificar a severidade de doenças foliares na cultura e grau de desfolha de plantas. De modo geral, o aumento da densidade de plantas proporcionou maior severidade de doenças de final de ciclo, intensificando a desfolha de plantas em ambas as cultivares de soja.

Understanding trigonometry relational system is a school mathemat-ics demanding topic. The angle, the unit circle and the trigonometric functions are its foundational notions. Trigonometric contents mean-ing and their understanding involve these three concepts and their re-lationships. This research aims to deepen in the pre-service teachers’ understanding about the angle, the unit circle and the trigonometric function when converting notions between two trigonometric repre-sentation systems based on the unit circle and the trigonometric func-tions. The results indicate that pre-service mathematics teachers’ pre-sent a lack of connections between the goniometric and the analytical representation system.
Pre-service teachers’ challenges in implementing mathematical modelling: Insights into reality
Authors: Guerrero Ortiz Carolina , Borromeo Ferri Rita
Published: July 2022

Modelling has become mandatory in the school curricula in many countries across the globe, often without providing teachers the training needed to address this challenge. With a qualitative case study, we analyzed the tasks designed by secondary mathematics pre-service teachers. We recognized how participants manage their knowledge for teaching modelling in the absence of training. Elements of knowledge for teaching such as translation between languages, recognizing unknown data, covariation, and usefulness of representations for understanding and solving problems, were identified. Our results also reveal that future teachers have a tendency to create word problems when first attempting to teach modelling.
