MEDIA PLAYER CONTROLLING USING HAND GESTURES
Authors: CHOUDHARY ANSHUL , PRIYANKA R. , SINGH SHIVANSH
Published: May 2023

In the modern world, everyone prefers speedy interactions with
intricate mechanisms that guarantee a prompt response. Response time and
ease of use are therefore problems as technology continues to advance.
Here is where human-computer interaction comes into play. With the aid
of OpenCV and Python, we attempt to use hand gestures to control our
media player in this project. In linguistics, hand gestures are a
crucial part of body languages. The use of the hand as a device makes it
simple to interface with humans and computers. The importance of gesture
recognition has grown significantly. Different apps, such as Windows
Media Player, robot control, gaming, etc., are controlled by hand
gestures. Interaction is simple, practical, and requires no additional
equipment when gestures are used.
Prior self-control exertion decreases pre-frontal cortex oxygenation during a CO2 rebreathing challenge but does not affect perceptions of dyspnoea or tolerance time.
Authors: Brown James , Boat Ruth , Williams Neil , Johnson Michael , Sharpe Graham
Published: May 2023

Introduction: Recently, we showed that males high in trait self-control
experience less dyspnoea and persist for longer in a carbon dioxide
(CO2) rebreathing challenge than males low in trait self-control. As
self-control can also vary within individuals (state self-control), the
aim of the present study was to investigate whether prior self-control
exertion influenced perceptions of dyspnoea and tolerance to a CO2
rebreathing task in healthy young males. We also used functional
near-infrared spectroscopy (fNIRS) to assess haemodynamic activity of
the pre-frontal cortex as it is the primary brain region associated with
exertion of self-control. Methods: Participants completed a congruent
Stroop task (control condition) and an incongruent Stroop task (prior
self-control exertion) followed by a CO2 rebreathing challenge until the
limit of tolerance. Changes in oxyhaemoglobin (ΔO2Hb) and
deoxyhaemoglobin (ΔHHb) from baseline, were assessed continuously in the
Stroop task and CO2 rebreathing challenge. Dyspnoea intensity and
unpleasantness were rated every 30s. Results: There was no effect of
prior self-control exertion on perceptions of dyspnoea or tolerance time
in the CO2 rebreathing challenge (all P > 0.05). Average
ΔO2Hb from baseline was higher in the difficult Stroop task (prior
self-control exertion, 4.25±1.80µM) than the easy Stroop task (control
condition, 2.82±1.45µM, P = 0.011). During the subsequent CO2
rebreathing challenge, ΔO2Hb was attenuated following prior self-control
exertion.(6.47±2.87µM) compared to the control condition (7.82±2.68µM, P
= 0.012). Conclusions: Pre-frontal cortex oxygenation was lower in a
subsequent CO2 rebreathing challenge following prior self-control
exertion. There was no effect of prior self-control exertion on
dyspnoea.
European Capital of Culture Plovdiv 2019: Effects through the lens of the local community
Authors: Dogramadjieva Elka , Tylko Kalina
Published: April 2023

The paper deals with the impacts of hosting the European Capital of Culture
(ECOC) by the Bulgarian city of Plovdiv in 2019 through the lens of the
local community. Based on a survey conducted in 2021 with 444 residents, the
perceived effects of the initiative were discussed in four domains: (1)
Cultural, (2) Economic, (3) Social, and (4) Urban environment and
atmosphere. Descriptive statistics techniques and analysis of variance were
applied to interpret the data and outline the differences in the perceptions
affected by respondents? socio-demographic characteristics. The findings
indicate that in general, the ECOC impacts are perceived rather positively,
although the locals are hesitant if benefits outweigh the costs incurred.
None of the impacts is perceived as high by the survey participants, with
mean values of agreement hardly reaching four on a 5-grade scale. The most
recognized positive effects refer to the city?s cultural life and the
opportunities for local artists to perform; next come benefits for tourism
development and promotion along with improvements in urban environment and
infrastructure resulting from the ECOC implementation. Less clearly
perceived are negative effects such as the price rise and the preference
given to tourists over the locals. Significant differences in perceptions
are determined by respondents? education, personal involvement in the ECOC
organization, age, gender, and sphere of professional activity. However,
such differences are found in roughly half of all 22 statements under study,
meaning that certain perceptions depend on the socio-demographic profile
while others do not.

Published: April 2023

With the development of the high-end equipment manufacturing industry, the requirements for the surface performance of critical components are likewise increasing. To control the heat and mass transfer in the laser surface treatment process more efficiently and flexibly, the multiangle double laser surface treatment technology shows unique advantages. This study is focused on the experimental study of the laser surface treatment process for Ti6Al4V material. By changing the laser power and the incidence angle of the laser beam, the effects of single-laser beam surface treatment (SLST) and dual-laser beam surface treatment (DLST) on the surface morphology of the alloy were studied. The effects of laser treatment on the surface morphology, element distribution, roughness, surface chemical state, and surface structure of the alloy were emphatically analyzed. The mechanism of SLST and DLST at different incident angles of heat source and the effect of DLST on the formation of an oxide layer on the surface of the alloy were compared and analyzed. The results show that when the average power of the high-power nanosecond pulse width laser in DLST is 100 W and the incident angle is 135°, the surface oxygen content reaches the lowest, as low as 8.31%. The secondary effect of the laser makes the alloy surface remelt again, and then the best roughness after laser processing is obtained, with a roughness value of 2.801 μm. Finally, we obtain the optimal process for laser surface treatment and conclude that DLST can significantly optimize the surface state after a high-energy laser beam action.

Implementation of a Teaching Scenario for Fifth-Grade Students Using the Software “MATHEMA” as a Teaching Tool: The Phenomenon of Light Reflection
Authors: Evangelou Filippos , Kotsis Konstantinos
Published: May 2023

In this paper the implementation of a teaching scenario on the phenomenon of light reflection for 55 students of the fifth grade of primary school is analyzed in detail. The novelty of this teaching scenario lies both in the fact that it is based on the use of the teaching tool/simulation software “MATHEMA” as a cognitive tool and in the fact that the pedagogical approach used is based on the principles of the constructivist approach. This teaching scenario consists of the following two parts: a) The teaching organization guide and b) The students’ worksheets. The SOLO method - taxonomy - is used to assess the learning outcomes. Based on the learning outcomes, a significant shift in students’ responses towards the scientific model was observed after the experimental interventions. Consequently, a conceptual change was achieved, to some extent, after performing the virtual experiments. The results presented in this study support the argument for the learning value and contribution of simulation software as a teaching tool in science teaching and learning.

Published: May 2023

Biological fertilizers are a group of living organisms whose activities can improve soil fertility, fertilizers that contain microbes and are useful for helping plant growth. The purpose of this study was to analyze the growth and production of rice plants against the application of biological fertilizers. There are 7 bacterial isolates used as biofertilizers, namely, Bacillus sp., two Pseudomonas sp. strains, two Azospirillum sp. strains, and two Azotobacter sp. strains. This study used an experimental design method through a one-factor randomized block design. The treatment in the study consisted of no fertilization, compost, 100% NPK, 7 isolates enriched compost, 7 isolates enriched compost+50% NPK, 4 isolates enriched compost, and 4 isolates enriched compost+50% NPK. The results showed that compost enriched with biological fertilizers could increase the nutrient content of the soil, thereby increasing the growth and production of rice plants. Treatment of compost enriched with 7 isolates+50% NPK gave the highest yield, both for rice plants. The use of biological fertilizers can reduce the dose of inorganic fertilizer use by up to 50% in rice cultivation.

The purpose of this study was to determine the virulence genes and antimicrobial resistance patterns of Escherichia coli isolated from milk samples of cows with bovine mastitis. Forty-seven E. coli isolates from clinical mastitis milk samples, from five dairy farms in Northeast of Iran, were subjected to multiplex PCR to determine virulence genes stx1, stx2, eaeA, hlyA, sta, F4, F17, fliC, and rfbE. In addition, antimicrobial susceptibility was assessed by applying disk diffusion methods. The eaeA and stx1 genes were most frequently detected in 42 (89.3%) and 34 (72.3%) isolates, respectively. However, the least frequent gene was F41 as it was found in only one isolate (2.1%). Furthermore, 9 out of 47 isolates were hlyA positive, and four isolates harbored the sta gene. The antimicrobial susceptibility demonstrated the highest resistance against lincomycin (100%) and neomycin (91.4%). Since these bacteria represent a high-risk pathogen on farms, the emergence of multiple antibiotic-resistant and pathogenic E. coli strains should be of great concern for public health.

Abstract Culture is something that is unique and can be a characteristic or identity of an area that is formed from daily habits. Without realizing it, culture is closely related to education, one of which is mathematics. Because culture can be used as a learning media associated with realistic learning styles, culture as a learning medium can be used by educators in the learning process, especially in mathematical concepts. Learning mathematics that is done with a cultural approach is called ethnomathematics. Ethnomathematics is a realistic mathematics learning approach that bridges mathematics learning through local culture. The purpose of this research is to explore Trenggalek's Turonggo Yakso Batik Motif and to describe the mathematical concepts in Turonggo Yakso's Typical Batik elements Trenggalek. This research is a type of qualitative research using an ethnographic approach. The results of this study indicate that the characteristics of the Turanggo Yakso Typical Trenggalek Batik Motif can be implemented as a medium for learning mathematics in the following materials: flat shape, folding symmetry, rotational symmetry, angles, reflection, congruence, and congruence. AbstrakBudaya adalah hal yang unik dan dapat menjadi penciri atau identitas dari suatu daerah yang terbentuk dari kebiasaan sehari-hari. Tanpa disadari budaya berkaitan erat dengan pendidikan, salah satunya dengan mata pelajaran matematika. Hal tersebut karena budaya dapat dijadikan sebagai media pembelajaran yang dikaitkan dengan gaya belajar realistik. Budaya sebagai media pembelajaran dapat digunakan pendidik dalam proses pembelajaran terutama pada konsep matematika. Pembelajaran matematika yang dilakukan dengan pendekatan budaya disebut dengan etnomatematika. Etnomatematika merupakan pendekatan pembelajaran matematika realistik yang menjembatani pembelajaran matematika melalui budaya setempat. Tujuan dari penelitian ini adalah mengeksplorasi Batik Motif Turonggo Yakso khas Trenggalek dan mendeskripsikan konsep matematika yang ada pada unsur Batik Motif Turanggo Yakso Khas Trenggalek Penelitian ini merupakan jenis penelitian kualitatif dengan menggunakan pendekatan etnografi.

WHICH IS MORE RELATED TO LITERACY SKILLS, COMPETITION OR COOPERATION? EVIDENCE FROM PISA 2018 RESULTS
Authors: Rasmuin Rasmuin
Published: May 2023

Although previous research has demonstrated that school climate (leading to a climate of competition or cooperation) is related to student achievement, including their literacy skills, there is still insufficient evidence which of the two school climates is more related to literacy skills. Therefore, this study examined the relationship between the two sets of variables in the PISA 2018 Results data: students’ perceptions of school climate (PERSCHL) and literacy skills (LITERACY). The PERSCHL set consists of perceptions of the level of competition (PERSCOMP) and cooperation (PERSCOOP) in schools, while LITERACY set consists of mathematical literacy (MATH), reading (READ), and science (SCIE). The research was conducted to answer the questions: (1) is there a relationship between a student’s perception of competition and cooperation with students’ literacy skills? and (2) which one of the two PERSCHL variable sets has the most influence on students’ literacy skills? The level of perception in the PERSCHL set was estimated using the Graded Response Model (GRM), while literacy skills was calculated from the average of 10 Plausible Value (PV) that has been available in the data of PISA 2018 Results. The research hypothesis was tested using canonical correlation analysis. The results of the data analysis showed that the positive students’ perceptions of competitive and cooperative school climate had a positive and significant association with literacy skills although with a small correlation index. Second, perceptions of competition have a higher relationship with literacy skills than perceptions of cooperation in schools but the difference between the two is small. Both competition and cooperation in schools still need to be developed to facilitate the improvement of student literacy skills individually and collectively.

Authors: Prasetyo Freddy , Suhendra Suhendra , Turmudi Turmudi
Published: May 2023

Over the last few decades, many studies have placed attention on math anxiety in students, but math teachers can also experience anxiety that requires the attention. Math teachers can experience the anxiety in the form of math anxiety and math teaching anxiety, which can affect the learning process of mathematics. The purpose of this study is to identify the factors that cause math anxiety and math teaching anxiety in teachers. The method used in this research is Systematic Literature Review (SLR) with a survey-based descriptive approach through analysis the articles that fulfilled the inclution criteria, namely (1) published during the last ten years (2013-2022), (2) written in Indonesian or English, (3) indexed by Scopus or Sinta, which are browsed on the Google Scholar, ERIC, and Garuda database using the keywords “teachers’ math anxiety" and “teacher’s math teaching anxiety”. The results showed that mathematics teachers who experience mathematics anxiety in the form of feelings of worry and discomfort when thinking or doing something related to mathematics, this is caused by a low level of mathematics knowledge and self-confidence, while mathematics teaching anxiety causes worry and feeling uncomfortable when going to or teaching mathematics, this is caused by several factors such as experiencing mathematics anxiety, low mastery of learning technology, low levels of self-confidence, and unsupportive learning infrastructure.

Published: May 2023

Learning mathematics is frequently regarded as difficult by students, resulting in a lack of problem-solving ability. This problem occurred at SMPN 8 Jember, where, based on the results of observations, grade VII students have low problem-solving skills due to the conventional learning model used. If the problem is not addressed immediately, it is feared that it will continue with the next generation of students. This study aims to determine the effectiveness of PBL model of the peer tutor method assisted by card problems on mathematics learning outcomes in seventh-grade junior high school students with quadrilateral material. This research includes a quasi-experimental design. The data collection technique uses pretest and posttest tests to be tested with the paired samples T test and regression test (ANOVA) on the SPSS application. The results of the paired samples T test in the experimental class gave a sig value of 0.000, while in the control class it was 0.003. The sig value for the regression test for the experimental class is 0.014, while the sig value for the control class is 0.033. These results show that the PBL model of the peer tutor method assisted by card problems is more effective and influential than the PBL model of the peer tutor method to improve student mathematics learning outcomes. The study concludes that incorporating card problem learning media into the PBL model of the peer tutor method produces effective results in terms of quadrilateral material mathematics learning outcomes.
Dynamics of the development of choreographic culture and education
Authors: Kyrylenko Inesa
Published: May 2023

Relevance of research. Under conditions related to the reformation of the national education system in general and in the field of art in particular, when priority cultural values and ideals are being reassessed and rethought, it is becoming necessary to turn to those historically formed pedagogical traditions of choreographic education and culture, which, on the one hand, must be preserved, and on the other hand, adapted to the new conditions of the Ukrainian cultural, economic and political reality. The purpose of the article is to analyse the peculiarities of the development dynamics of the Ukrainian choreographic culture and education. These research methods are used: general scientific (analysis, synthesis, systematisation, comparison, generalisation, comparison) in order to clarify the historiography of the problem under study; historical (historical-structural, historical and genesis-based, historical-diachronic, criterial-complex) ensured the development of the research structure; made it possible to reveal the origins of the development of choreographic education and culture. The content of the study and its results. The article examines the peculiarities of the development of the Ukrainian choreographic culture and education in the context of general cultural trends of a certain era. Special attention is paid to the national cultural tradition, the spiritual sphere of society, the change of the general cultural paradigm, the functions of choreographic education and culture. It is noted that the problem of the dynamic development of modern dance art is closely related to the incessant civilisational and socio-cultural progress, the change in the format of psychological and pedagogical approaches, methods and means of choreographic education. The domestic system of choreographic education was formed in the process of long-term acculturation. The specificity of dance education lies in its bicentricity: it is equally closely connected with the educational sphere and with the artistic and performing practice of art. The reformation and development of modern stage choreography took place through the dialectical denial of academic traditions and the construction of new choreographic forms. Under conditions of the cultural and philosophical era of postmodernism, the phenomenon of modern stage choreography is considered as a stylistic reflection of the artistic trends of synthesis.

Published: May 2023

OBJECTIVE

To report the outcome of locally administered antibiotic-impregnated poloxamer 407 (P407) hydrogel in dogs diagnosed with orthopedic surgical site infections (SSIs) and to identify risk factors for treatment failure.

ANIMALS

34 client-owned dogs diagnosed with an orthopedic surgical site infection treated with local antibiotic-impregnated P407 hydrogel.

PROCEDURES

Medical records were reviewed of dogs receiving antibiotic-impregnated P407 hydrogel for an active orthopedic SSI between March 2018 and December 2020. The rate of successful infection clearance was calculated. Risk factors for failed treatment were evaluated with statistical analyses.

RESULTS

34 dogs met the inclusion criteria. Vancomycin-impregnated P407 hydrogel (20 mg/mL) was implanted in all dogs. The rate of infection clearance was 77%. Each unit increase in the number of surgeries performed at a site before gel implantation decrease the chance of successful infection clearance by 25% (P = .005; unit OR, 0.25; 95% CI, 0.08 to 0.81). Presence of multidrug or methicillin resistance increased risk for treatment failure by 7.69 times (P = .042; OR, 0.13; 95% CI, 0.01 to 1.14). No adverse events related to gel administration were seen.

CLINICAL RELEVANCE

Treatment outcomes were negatively impacted by the presence of multidrug or methicillin resistance and by an increased number of surgeries before gel implantation. Local administration of antibiotic-impregnated P407 hydrogel had a high success rate with no adverse effects in this population. Local antibiotic gel administration may improve treatment outcomes in dogs with complicated SSI.
Ponding time, hydraulic conductivity, and sorptivity – experimental and numerical determination
Authors: Kalibová Jana , Petrů Jan , Luca Melorio , Štibinger Jakub
Published: April 2023

Determination of actual soil sorptivity becomes one of the research preferences in the field of soil management and flash-flood protection. This Note presents an innovative approach to soil sorptivity determination. A single ring infiltration method, along with a simulation of rainfall of constant intensity, was used to measure ponding time t
p. Hydraulic conductivity K was approximated from the analysis of the time series of the process of vertical non-steady cumulative infiltration appearing after the ponding time. Based on Philip's infiltration theory, a simple equation was derived in order to calculate sorptivity S from ponding time, rainfall intensity, and saturated hydraulic conductivity. Numerically determined results of S show to closely correspond with theoretical values published in the literature. To the best of our knowledge, this process of numerical determination of K and S has not been published so far. Moreover, unlike the traditional methods, e.g. single or double-ring in filtration experiments, this method provides more precise and representative values of S, verified by ponding time, as the results refer to the original soil sorptivity, not the sorptivity determined after the ponding time (meaning sorptivity of the fully saturated environment) which tends to reach zero. Our assumption was definitely confirmed by field experimental determination of ponding time and selected soil hydrology characteristics.
A comparative corpus-based investigation of results sections of research articles in Applied Linguistics and Physics
Authors: Parviz Muhammed
Published: May 2023

The present study sought to identify the generic structures of the results sections of scientific research articles (RAs) between Applied Linguistics and Physics. Following a manual search approach, a total of 200 RAs in the field of Applied Linguistics and Physics from different top prestigious journals randomly were singled out and analyzed. In addition to offering a tentative template for the rhetorical organizations of results sections, the findings revealed shared and non-shared rhetorical units as well as obligatory and optional steps in the results sections (RSs) of research articles between the disciplines. The findings also indicated that RA writers organize the contents of the RSs around certain rhetorical resources (i.e., M1, M2, M3, M4, and M5) to present key experimental and factual analytical results of their studies. The findings further suggested the existence of common core of rhetorical resources in writing RSs between the disciplines, albeit there are a set of certain steps playing an essential part in distinguishing textual features of each discipline as well as depicting how RSs of individual discipline are developed. The findings generated from the study can offer a number of important pedagogical implications for teaching EAP and ESP courses, especially for Applied Linguistics and Physics teachers and students.

“Teaching old dogs new tricks” – POCUS Education for Senior Faculty
Authors: Restrepo Daniel , Heyne Thomas , Schutzer Christine , Dversdal Renee
Published: April 2023

Point of care Ultrasound (POCUS) is a growing diagnostic modality across a variety of specialties and is increasingly being taught in undergraduate medical education. Uptake within internal medicine has been slow but is becoming more commonplace. Training of extant hospital medicine faculty, including senior members, in POCUS is an unmet need in graduate medical education with significant pedagogical and patient safety implications. With this in mind, we created a training program for the core teaching faculty at our academic internal medicine residency program. The experiential, hands-on curriculum explored the reasoning behind concepts and emphasized psychological safety for senior faculty learners and was successful and well-received. In our piece, we aim to explore the existing literature around training this unique population in POCUS and report on our single-center experience. We also provide a framework for how our program succeeded, collate tips derived from the expert ultrasound teachers and list pearls learned while teaching these experienced educators. Although this worthwhile effort requires planning and support, it was appreciated even by senior faculty.

Point of care ultrasound (POCUS) in Canadian undergraduate medical education (UGME) is limited. To address this paucity, the inaugural Seguin Canadian POCUS Education Conference hosted 14 of the 17 Canadian medical schools to develop a list of recommendations for POCUS education in Canadian UGME. Attending schools were divided into delegations consisting of a pre-clerkship student, a clerkship student and a staff physician. Recommendations were developed via a modified consensus development panel. Delegations submitted school-specific POCUS education summary documents for roundtable discussions, which yielded an initial set of recommendations. These were then summarized in a large group setting and voted upon for adoption with an a priori agreement threshold of 80%. Conference attendees developed 14 recommendations which 87% of participants agreed to adopt. Conference recommendations reflect the opinions of Canadian trainees and POCUS education experts thus serving as a framework for UGME POCUS education in Canada.

Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response to infection with a high mortality rate. Septic shock is a subset of sepsis with manifest circulatory dysfunction (use of vasopressors and persistent elevation of lactic acid). As stated in literature, in addition to the use of empiric antibiotics and control of the infectious focus, intravenous fluid therapy is an essential intervention to promote hemodynamic stabilization. However, the literature also describes harmful outcomes related to fluid overload. Hemodynamic management in critically ill patients has traditionally focused on maintaining adequate cardiac output and arterial blood pressure by relying on fluid administration and/or vasopressor/inotropic support. However, organ perfusion is affected by other important factors, such as venous pressure, which can be overlooked. The evaluation of lung congestion with point of care ultrasound (POCUS), as a signal of extravascular fluid, and, more recently, a venous excess Doppler ultrasound (VExUS) grading system, are parameters for the assessment of the fluid status of the patient and organ congestion. Our main hypothesis is that adding a modified lung ultrasound score to the VExUS protocol could provide higher sensitivity and earlier identification of fluid overload, guiding the clinician in the decision of fluid administration in patients with sepsis.

Dental health is a common problem in society. Traditionally, siwak is used to prevent bleeding gums and has antimicrobial effects. In this study, a tooth serum was made from ethanol extract of siwak and its preparations were evaluated and its antibacterial effect was tested. The method used in this research was experimental and three formulations were made with different concentrations of ethanol extract of siwak, formulation 1 (21%), formulation 2 (42%), and formulation 3 (63%). The results of the preparation evaluation showed that the three formulations were not significantly different compared to the control based on organoleptic test, viscosity, pH, dispersion, and stability test. The antimicrobial effect test showed that the three formulations were able to inhibit streptococcus mutans. After the research, the conclusion that can be taken is that the three formulations of the tooth serum ethanol extract of siwak are pharmaceutically stable and formulation 3 showed the best antibacterial effect.

The control loop in the industry is a component that must be maintained because it will determine the plant's performance. Most industrial controllers experience oscillations with various causes, such as noise, oscillation, backlash, dead band, hysteresis, random variation, and poor controller tuning. The oscillation diagnosis system, which can understand the oscillation type characteristics, is built based on machine learning because it is dynamic and not based on specific rules. This study developed an online oscillation diagnosis program using the extreme gradient boosting (XGBoost) method. The data was obtained through the simulation of the Tennessee Eastman process. The data is segmented on specific window sizes, and then time series feature extraction is performed. The extraction results are then used to build an XGBoost model capable of performing oscillation diagnosis tasks. There are seven types of oscillations tested in this study. The model that has been made is implemented online with the help of sliding windows. The results show that the XGBoost model performs best when the data window size is 100, with the accuracy performance and the F1 score of the model in classifying the type of oscillation being 0.918 and 0.905, respectively. The model can detect the type of oscillation with an average diagnosis time of 712 seconds on diagnostic tests.

This research work is based on the realization of a prototype of a mobile app for the learning of algorithms for university students applying the methodology of design thinking because nowadays, this methodology is becoming more popular and used by many companies for its iterative processes in which we seek to understand the user and redefine problems in an attempt to identify strategies and solutions alternatives that might not be instantly apparent with an initial level of understanding. Using this methodology, we identified and designed what users needed, focusing on UI and UX with the info we recollected from the many interviews and forms we made. The results of this research were the complete prototype for the subsequent development of the mobile app on future projects and much feedback that we will consider from the final users to improve the app. Thanks to this app, many students can practice and learn about different algorithms and expand their minds to generate solutions to one problem.
