Congenital malformations are not only a medical, but also a serious social problem, since this pathology is a leading cause of perinatal, neonatal, and infant morbidity, disability, and mortality.Purpose. To analyze the variation dynamics in the incidence of groups of congenital malformations, the structure of congenital malformations according to the average incidence, and the consistency of changes in the incidence of individual groups of congenital anomalies in children of Chelyabinsk based on the results of epidemiological monitoring in 2012–2017.Material and methods. To assess the frequencies of congenital malformations, we used the monitoring data of the Regional Medicaland Genetic Consultation Office in Chelyabinsk for the period from 2012 to 2017, for Down syndrome (T21) from 2012 to 2018. The total number of newborns over the six-year period was 102,308, of which 2101 children were registered with congenital malformations, including live-born, stillborn children, and fetuses with malformations identified through prenatal diagnostics. Clinical data on newborns was grouped into 11 congenital malformations categories based on the International Classification of Diseases. The statistical analysis of the monitoring results was carried out using methods of descriptive statistics, samples comparisons, correlation, and cluster analysis.Results. The incidence of all registered congenital malformations in newborns in Chelyabinsk was 20.7 per 1000 births (95% CI: 17.4–25.4) during the study period. In newborns of the Chelyabinsk city in 2012–2017, the prevalence of congenital malformations of the circulatory system (42.8%), chromosomal abnormalities (11.9%), and anomalies of the musculoskeletal system (10.3%) was observed. The relative frequency of Down syndrome for the period from 2012 to 2018 ranged from 1.51‰ to 2.42‰, considering both children born with this pathology and the data on prenatal diagnostics.Conclusion. The hierarchy of congenital malformations was reproduced from year to year with a predominance of circulatory anomalies, chromosomal anomalies, and musculoskeletal anomalies of the system. The overall incidence of all congenital malformations in Chelyabinsk in 2012–2017 does not exceed the average values for the Russian Federation, while the incidence of Down syndrome exceeded the average national level.

It is known that blood pressure in children at rest depends on height, but this fact has not been considered during the exercise stress test.Purpose. To determine the maximum value of blood pressure in young elite athletes, depending on the height and gender.Characteristics of children and research methods. The study examined 2313 young elite athletes, members of the national teams of the Russian Federation in 40 sports disciplines (average age — (15.5 ± 1.4) years; 45% of young men). All subjects underwent PWC170 cycle ergometry, blood pressure was measured manually at each stage of testing, and its maxima were registered throughout the testing.Results. The maximum blood pressure values in boys were higher than in girls: systolic blood pressure (195 ± 25) vs (175 ± 20) mmHg, p< 0.001, diastolic blood pressure (80 ± 11) vs (80 ± 10) mmHg, p< 0.05. There was relationship between the maximum value of the blood pressure on exercise and height (r= 0.55; p< 0.001). There were proposed normative tables for the maximum values of systolic blood pressure during exercise, depending on height.Conclusion. In the young elite athletes, the maximum value of blood pressure during stress test depends not only on the gender, but also on the height. The maximum values of systolic blood pressure during exercise in tall young elite athletes can reach 250 mmHg in boys and 210 mmHg in girls.

Islã: É possível um Diálogo Cultural?
Authors: Cidrão Taís Vasconcelos , Jorge Neto Nagibe de Melo
Published: August 2022

Este artigo propõe uma reflexão sobre a possibilidade do uso da cultura na formação da lei islâmica e sobre a existência de uma substrato cultural comum que sirva de fundamento para os direitos humanos ou, quem sabe, como caminho de diálogo entre o mundo islâmico e o mundo ocidental. Analisa-se, por meio de um estudo bibliográfico e documental, a hipótese de a cultura ter, de fato, refletido no momento histórico-social e cultural da própria criação do Islã. Os críticos não islâmicos afirmam que a cultura influenciou a formação do Alcorão e da sunna, minando, assim, a legitimidade da lei islâmica. Os estudiosos muçulmanos, por outro lado, defendem que o Alcorão contém a palavra de Deus e que a sunna é o exemplo divinamente inspirado do profeta, assim, reivindicações de influência cultural simplesmente não se aplicam. Como demonstrado, esse desacordo reduz-se a uma circularidade irresolúvel. O prognóstico aqui defendido é o de que, apesar de não se chegar a um consenso acerca da influência, os muçulmanos dispõem de metodologias necessárias e suficientes para embarcarem em um processo de reformulação da fiqh clássica, por meio da ijtihad, para refletir as realidades políticas, jurídicas e econômicas contemporâneas, sobretudo no que diz com os direitos humanos.
Respiratory Syncytial Virus is the Most Common Causative Agent of Viral
Bronchiolitis in Young Children: An Updated Review
Authors: Hon Kam L. , Leung Alexander K. C. , Wong Alex H.C. , Dudi Amrita , Leung Karen K.Y.
Published: August 2022

Background:

Viral bronchiolitis is a common condition and a leading cause of hospitali-zation in young children.

Objective:

This article provides readers with an update on the evaluation, diagnosis, and treatment of viral bronchiolitis, primarily due to RSV.

Methods:

A PubMed search was conducted in December 2021 in Clinical Queries using the key terms "acute bronchiolitis" OR “respiratory syncytial virus infection”. The search included clinical trials, randomized controlled trials, case control studies, cohort studies, meta-analyses, observation-al studies, clinical guidelines, case reports, case series, and reviews. The search was restricted to children and English literature. The information retrieved from the above search was used in the compilation of this article.

Results:

Respiratory syncytial virus (RSV) is the most common viral bronchiolitis in young chil-dren. Other viruses such as human rhinovirus and coronavirus could be etiological agents. Diagno-sis is based on clinical manifestation. Viral testing is useful only for cohort and quarantine purposes. Cochrane evidence-based reviews have been performed on most treatment modalities for RSV and viral bronchiolitis. Treatment for viral bronchiolitis is mainly symptomatic support. Beta-agonists are frequently used despite the lack of evidence that they reduce hospital admissions or length of stay. Nebulized racemic epinephrine, hypertonic saline and corticosteroids are generally not effec-tive. Passive immunoprophylaxis with a monoclonal antibody against RSV, when given intramus-cularly and monthly during winter, is effective in preventing severe RSV bronchiolitis in high-risk children who are born prematurely and in children under 2 years with chronic lung disease or hemodynamically significant congenital heart disease. Vaccines for RSV bronchiolitis are being developed. Children with viral bronchiolitis in early life are at increased risk of developing asthma later in childhood.

Conclusions:

Viral bronchiolitis is common. No current pharmacologic treatment or novel therapy has been proven to improve outcomes compared to supportive treatment. Viral bronchiolitis in early life predisposes asthma development later in childhood.

Published: August 2022

Cancer is a type of human cell degenerative disease that has afflicted a large number of people for years.
Cancer is caused due to the abnormal proliferation of cells in any part of the body. Most of the prescribed anticancer
drugs are synthetic in nature and have been reported with enormous adverse effects. The researchers are very much
enthusiastic about the use of natural compounds and their derivatives, which have been reported with less toxicity.
Natural compounds have emerged as promising synergistic compounds with potential anticancer effects. In vitro anticancer
activity of natural compounds with special reference to camphor and menthol has been investigated against
different cancer cell lines. It has been found that camphor and menthol derivatives have potential cytotoxic activity.
The present literature review outlines the various methods for the synthesis of camphor and menthol derivatives, which
have potential cytotoxic activity. It highlights various cancer cell lines, which are the target of these camphor and menthol
derivatives as ligands, along with structure-activity studies.

The results on measuring the I-V characteristics of the metal-semiconductor transition within the Ti(200nm)|Si@O@Al(179nm)|Ti(203nm) test structure are presented. The basis of the Si@O@Al nanocomposite is a solid solution of Al in amorphous silicon a-Si(Al). The I–V of the test structure has a form characteristic of a reverse-biased ohmic contact between a metal and a p-type semiconductor, which implies that a-Si(Al) is a substitutional solid solution. It is shown that the I-V fits well the framework of the metal-semiconductor transition model and the varistor effect of the nanocomposite. Within the framework of the percolation model, it is shown that the I–V give values of the Si@O@Al resistivity, which are overestimated with respect to the resistance of the a-Si(Al) solid solution.

The single electron capture process from adenine molecules by H+, 3He+, N+, O+, and Ne+ ions with an energy of 6.3 keV has been studied. It was found that when one electron is captured by He+ and Ne+ ions, the dissociative capture process is dominant, which is fundamentally different from the processes of capture by singly charged ions of atoms with a lower ionization potential and multiply charged ions, as well as from the process of electron impact ionization. This effect is qualitatively explained within the framework of a quasimolecular model.

Background

Chronic pelvic pain is a common and disabling condition in women living with endometriosis. Pharmacological and surgical treatments are not always effective at controlling pain and present important restrictions. Digital therapeutics (DTx) are emerging as major nonpharmacological alternatives that aim to extend the analgesic therapeutic arsenal of patients.

Objective

In this randomized controlled trial (RCT), we aimed to measure the immediate and 4-hour persisting effects of a single use 20-minute DTx (Endocare) on pain in women experiencing pelvic pain due to endometriosis.

Methods

A total of 45 women with endometriosis participated in a randomized controlled study comparing the analgesic effect of a single use of a virtual reality digital treatment named Endocare (n=23, 51%) to a 2D digital control (n=22, 49%). Perceived pain and pain relief were measured before the treatment and 15, 30, 45, 60, and 240 minutes after the end of the treatment.

Results

The clustered posttreatment pain was significantly reduced compared to the pretreatment for both Endocare and the control group (all P<.01). Endocare was significantly more effective than the control group (all P<.01). Endocare decreased the mean pain intensity from 6.0 (SD 1.31) before the treatment to 4.5 (SD 1.71) posttreatment, while the control only decreased it from 5.7 (SD 1.36) to 5.0 (SD 1.43). When comparing each posttreatment measures to the pretest, Endocare significantly reduced pain perception for all points in time up to 4 hours posttreatment. The differences did not reached significance for the control group. Moreover, Endocare was significantly superior to the control group 15, 30, and 45 minutes after the treatment (all P<.001). The mean perceived pain relief was significantly higher for Endocare at 28% (SD 2%) compared to the control, which was 15% (SD 1%) for all the posttreatment measurements (all P>.05).

Conclusions

Our study aimed to test the effects of a single use of a DTx treatment on reported pain at different time points in women diagnosed with endometriosis experiencing moderate-to-severe pelvic pain. Importantly, our results support that Endocare, a virtual reality immersive treatment, significantly reduce pain perception compared to a digital control in women living with endometriosis. Interestingly, we are the first to notice that the effect persisted up to 4 hours posttreatment.

The Influence of Eco-friendly Ash on Sustainable Construction Material: A Review
Authors: Prabagar Subramaniam , Thuraisingam Suganja , Prabagar Jasotha
Published: August 2022

Nowadays climate change is one of the major concerning factors due to increasing temperature throughout the world. Carbon dioxide is a significant gas in the greenhouse effect which leads to global warming. The construction industries released 40% carbon emissions from thermal calcium carbonate decomposition especially in cement production and combustion of fossil fuels of non-renewable energy. Renewable energy acts a vital part in the evolution of sustainability. Bioenergy has been deliberated carbon neutral as the released carbon is absorbed by flora. This paper presents a comprehensive review of the pozzolanic properties of waste ash and the performance of concrete. Ash is a by-product produced from various resources such as rice husk, wood, coal, sawdust combustion, etc. Waste ash is reused as supplementary material in eco-friendly concrete production. This helps for the disposal of waste as well as contributes the sustainability by reducing carbon emission into the environment.
An Acoustic Study of Emphasis Spread in Najdi Arabic
Authors: Alsuhaibani Alwaleed A.
Published: August 2022

As with other varieties of Arabic, Najdi Arabic (NA), spoken in central Saudi Arabia, contains a set of emphatic consonants, /? – ? – ð?/, which have an uncontrollable phonological effect on neighboring segments whereby the presence of an emphatic in a word entails “emphasis spread” to the adjacent non-emphatic segments. Acoustically, emphasis is manifested by lowering the frequency of the second formant (F2) of vowels in the vicinity of an emphatic. The purpose of this study is investigate the domain and directionality of emphasis spread in NA and whether it is blocked by any opaque phonemes by measuring and comparing the F2 frequencies of vowels in minimal pairs contrasting on the basis of the presence/absence of emphatics. The results show that the domain of emphasis spread in NA is the entire phonological word consisting of the stem plus any inflectional/derivational affixes. In addition, emphasis spreads rightward and leftward throughout the phonological word in a gradient manner in an inverse relationship, where emphasis peaks in the syllable containing the emphatic and gradually decreases as it moves into the following/preceding syllables. Finally, the high front phonemes /y – ? – ?/ act as opaque segments as they block rightward spread but not leftward spread.
Yombil “Puesta su flor en el altar”. Una mirada a la etnomedicina en Oxchuc, Chiapas, a partir de los j-poxtawanejetik organizados

Published: August 2022

La investigación que tiene ante sí pretende dar cuenta, desde la perspectiva de la determinación histórica de los fenómenos sociales, del devenir de las formas particulares de cosmovisión y etnomedicina que han estado presentes entre los tseltales de Oxchuc. En el proceso que se suscitó como resultado de la colonización, los “pueblos de indios” de Los Altos de Chiapas fueron conformados con población de distintos orígenes. Lo cual tuvo como meta romper los fundamentos socioculturales y organizativos prehispánicos y con ello lograr el control social, vencer resistencias, así como facilitar la expoliación de la población originaria. Dentro de este contexto, los tseltales de Oxchuc se distinguieron enormemente de sus vecinos hablantes de la misma lengua porque no fueron capaces de preservar suficientes elementos de la religiosidad prehispánica, tampoco de reelaborar con suficiencia los de proveniencia católica, en la conformación de sus representaciones como para darse una cosmovisión y una religión tan elaborada como la del resto de los pueblos de Los Altos de Chiapas, dando como resultado dos ámbitos, llamémosles sobrenaturales, claramente delimitados, mismos que también aparecen en este volumen.

Authors: Muhammad Sya'dullah Fauzi  , Adik Laila Fitri Nawangsari  , Rosyada Moh. Faza
Published: August 2022

This article aimed to find out what the role of behaviorist language acquisition theory in learning Arabic online from the perspective of BF. Skinner. This research was a literature review that explores information about the role of language acquisition theory in learning Arabic, especially the idea of behaviorism according to BF Skinner's view. This research showed that the theory of BF Skinner's language acquisition plays a role in learning Arabic because it can help teachers determine what kind of technology media and methods will be used by teachers in learning Arabic. In selecting technology media and learning methods, Arabic teachers should use Synchronous Learning-based media and techniques as much as possible. Synchronous Learning is online learning with direct communication, such as using the Zoom cloud meeting application. Because the purpose of learning Arabic can be achieved if there is habituation in the four language skills, the teachers can also determine the reward or reinforcement for Arabic language learners according to the learners' psychological condition so that learners will be encouraged to improve their language skills even in online learning conditions continuously.

Published: August 2022

Objectives The purpose of this study is to explore ways to revitalize democratic citizenship education emphasized in the general outline of the 2022 revised curriculum. To this end, the meaning, domain, and principle of democratic citizenship education were examined, and concrete practice cases were presented through the reorganization of the integrated social curriculum in the Department of Social Studies.
Methods The concept, domain, and principle of democratic citizenship education, the goals and content elements of democratic citizenship education in the social studies curriculum, and methods of democratic citizenship education in social studies were theoretically explored. For the application of democratic citizenship education in the high school integrated social studies department, a core topic was extracted from the textbook , a textbook approved by the Gyeonggi Provincial Office of Education, and practiced research was conducted.
Results Three examples of classes were presented by reorganizing the curriculum according to the core themes and elements of an integrated society. First, social issues as a controversial issue, second, the 2.28 movement as a place-based learning, and third, examples of peace and unification classes linked with creative experiences for fostering peace sensitivity were presented as discussion learning and project learning.
Conclusions As emphasized in the general summary of the 2022 revised curriculum, in order for democratic citizenship education to be reflected in all subjects, it is necessary for teachers to design the curriculum for school curriculum design through subjects and non-curricular activities. In addition, various methods need to be explored, such as training to strengthen teacher competency, accompany democratic practices and values, prepare standards such as ordinances and laws, and establish a democratic school culture and self-government activities.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Choi Soonri , Kang Soomin , Song Jihoon
Published: August 2022

Objectives This study observed the relationship between the Kolb’s experiential learning theory according to the learning styles and experiential learning steps to understand the changes in learning styles and experiential learning steps during an co-curricular program progressed online during COVID-19 pandemic.
Methods The data for this study has been collected during 3 semesters (Semester 1 of 2020 to Semester 1 of 2021) in the University in Gyeonggi-do province, South Korea. The collected data for the study are 111 essays used for a document analysis during this five-semester period. To analyze the learning styles on this online co-curricular program, two methods were employed. First, a categorization was performed according to the Kolb’s learning type using constant comparison, then the categorized data is expressed in a scatter plot based on the steps of Kolb’s experiential learning theory. Then, the characteristics of each learning type is presented according to the contents of the categorized data. Second, the categorized data that was analyzed to understand the experiential learning steps was then reconstructed to elucidate the relationship among the factors making up the leaning steps.
Results There were high percentages of “divergers” and “accommodators” among the students in this online co-curricular program, but less of the “convergers” and “assimilators” in the student group. In the experiential learning steps, it is shown that a concrete experience stage allowed the students to experience positive learning through a negative learning experience, and a reflective observation stage allowed the students to modify their behaviors and refresh their negative emotions related to the studies. Additionally, students were able to utilize supporting resources to effectively use the program as well as applying them during an abstract conceptualization, and ultimately learn to generalize their study strategy during the active experimentation stage.
Conclusions Current study elucidated that emotional support and other supporting resources on the learning material facilitated positive learning experiences in an online co-curricular program, and some theoretical implications as well as real-life applications are discussed in this article.
Effect of University Students self-efficacy in career decision-making on career-involved thinking and career stress: mediating effect of career adaptability mediating Effect
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Lee Soon Hee
Published: August 2022

Objectives This study was conducted with the purpose of examining how college students' career decision self-efficacy affects dysfunctional career involvement thinking and career stress, and whether there is a mediating effect on career adaptability in this process.
Methods For data collection, 248 university students from city D were sampled and a survey was conducted. In the process where the independent variable, career decision self-efficacy, affected the dependent variables, dysfunctional career thinking and career stress, the effect of career adaptability, a mediating variable, was verified. To analyze the mediating effect of career adaptability, SPSS 21.0 and AMOS 21.0 were used to analyze the data, and Hayes' Bootstrapping method was used to verify the mediating effect.
Results The self-efficacy of career decision-making of college students showed a negative correlation with dysfunctional career involvement thinking and career stress, and a positive correlation with career adaptability. It was confirmed that the higher the career decision self-efficacy, the lower the level of dysfunctional career involvement thinking and career stress. It was confirmed that there was a mediating effect of career adaptability on career stress. As a result of analyzing the gender difference between male and female students on the mediating effect of career adaptability, it was found that male students had a higher mediating effect than female students.
Conclusions Career experts should explore strategies to reduce dysfunctional career involvement thinking and career stress that hinder college students from displaying their career competencies. In the career education department and career counseling field of college students, it is necessary to try to change the cognitive factors suitable for the developmental stage of college students, and a microscopically differentiated career counseling approach should be taken in consideration of gender differences. In the current difficult and complex career environment, the direction of assistance from career experts was suggested so that college students can maximize their career adaptability and improve their sense of career efficacy.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kim hyunjun , Kim jinah , Lee sangsoo
Published: August 2022

Objectives This study intends to suggest the development and follow-up research direction of blended learning research by analyzing the trends and representative research topics of each period of blended learning related papers.
Methods Keywords were collected and refined for papers related to blended learning from 2011 to October 2021 in the journal database. The keywords included in the study before and after COVID-19 were analyzed for frequency and degree centrality, and the results were visualized.
Results As a result of quantitative change trend analysis, it was confirmed that there is a rapid increase after COVID-19. As a result of keyword analysis, the frequency and importance of keywords related to experimental research verifying the effectiveness of blended learning itself were high in the research prior to COVID-19. In research after COVID-19, it was confirmed that the frequency and importance of keywords related to development research such as class model development in non-face-to-face class situations were high. ‘Effectiveness Verification’ and ‘Experimental Research’, ‘Instructional Model Development’ and ‘Development Research’, ‘Experimental Research’ and ‘Academic Achievement’, ‘COVID-19’ and ‘Non-face-to-face Class Situation’ was confirmed to have a high relevance. As a result of the centrality analysis, before COVID-19, research was being conducted centered on the keywords of ‘Effectiveness Verification’, ‘Experimental Research’, and ‘University’. After COVID-19, research has been focused on the keywords of ‘Development Research’, ‘Mixed Learning Environment’, and ‘University’. In addition, it was confirmed that the keywords were grouped into four themes.
Conclusions Although blended learning related papers have achieved steady quantitative growth over the past 10 years, previous studies have a limitation in that the proportion of microscopic studies focused on effectiveness verification and instructional model and program development was high. For the balanced development of blended learning research, it seems necessary to understand blended learning from a more macroscopic point of view in future research and field application, and to approach systematically from the instructional design stage, which is the basis of class operation.

Published: August 2022

Objectives The purpose of this study is to test the moderated mediating effects of communication with parents and school life on relations between adolescents' discrimination experiences and suicidal ideation.
Methods The study analyzed the data of 6,291 middle and high school students from “2019 Survey on the Human Rights of Children and Adolescents” by the National Youth Policy Institute and set discrimination experiences as an independent variable, suicidal ideation as a dependent variable, communication with parents as a parameter, and school life as a moderating variable in the research model.
Results The analysis results show that adolescents' discrimination experiences had positive effects on their suicidal ideation and that communication with parents played a mediating role between them. School life had moderating effects between discrimination experiences and communication with parents and also between discrimination experiences and communication with parents and suicidal ideation.
Conclusions School life had moderated mediating effects as the positive school life of adolescents alleviated the mediating effects of discrimination experiences increasing suicidal ideation via communication with parents. Based on the findings, the study proposes to refrain from hierarchical and one-sided communication at home and school and reinforce whole person education based on connections between school and home so that adolescents can ultimately suffer less damage from discrimination experiences.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Heo Haeja , Kim Soomi
Published: August 2022

Objectives It is to examine the mathematical mindsets of pre-primary and secondary school teachers in Korea and the mathematical beliefs that affect them.
Methods A survey was conducted on 108 pre-service teachers who will be elementary, middle or high school teachers in the near future and verification of differences between groups was verified using SPSS's t-test and ANOVA. In addition, the correlation between the mathematical mindset and other factors was analyzed.
Results The average math beliefs and math mindsets of pre-service teachers were slightly above 3 on a 5-point scale, respectively. In addition, there was a tendency for mathematical beliefs and mathematical mindsets to change negatively as the grade rises. However, although there were no differences by university, gender, and high school, the interaction effect of gender by university was significant in math self-concept, and male students in both universities had higher math self-concept than female students. In addition, math mindsets were found to be correlated with self-concept, mastery orientation, and belief in mathematics.
Conclusions As the existence of preliminary teachers with fixed mindsets has been confirmed, teacher education institutions should devise measures to explicitly guide preliminary teachers to the theory of growth.

Published: August 2022

Objectives The purpose of this study was to analyze error types in the connection between concepts and representations used by high school students in solving the meiosis problem, and to analyze the difference in the frequency of error types between science high school and general high school students.
Methods The subjects were 75 science high school and 93 general high school, a total of 168 students. The connection between concepts and representations used by students in solving the meiosis problem was analyzed. First, errors in each stage of meiosis were classified by Masnick & Klahr(2003), and then error types were analyzed in terms of the connection between concepts and representations by Kang, Lee, & Noh(2008).
Results As a result of the study, error types in the connection of concepts and representations that appeared in solving the meiosis problem could be divided into 10 types. As a result of analyzing the frequency of error types, it was confirmed that the level of understanding of meiosis was not relatively high because each study subject had an average of 2.3 error types. The most common types of connection errors between concepts and representations were ‘failing to connect’, ‘impossible connection’, and ‘insufficient connection’. The error types of science high school and general high school students showed a significant difference only in ‘impossible connection’, but there was no significant difference in the other types.
Conclusions Through the causes and solutions of connection errors between concepts and representations, it will be possible to help students prevent errors in genetic learning as well as in meiosis learning. In addition, it is expected that the wrong use of representations will be prevented, and students' connection errors will be reduced and used in learning strategies to improve the understanding of scientific concepts.

Published: August 2022

Objectives The purpose of this study is to explore the direction of music class based on the distribution of situation-related elements in music curriculum documents and music textbooks by considering situational learning.
Methods To this end, the situational learning theory was examined, and then the patterns and ratios of the discovered key elements were analyzed in the music curriculum documents and music textbooks. Music curriculum document, the distribution patterns of the relevant elements were analyzed with a focus on personality, objective, and achievement standards. Textbooks were analyzed by selective sampling 6th grade music textbooks. The curriculum focused on personality, goals, and achievement standards, and textbooks were selectively sampled and analyzed from music textbooks in the 6th grade of elementary school.
Results As a result, first, it is necessary to consider a long-term learning plan for a continuous musical situation, second, constructing a contextual activity that can form a musical identity, and third, musical interaction through a situation in which music is connected was discussed.
Conclusions It was concluded that praxis music learning through situations requires efforts to improve the learning conditions by accompanying outside classroom conditions between subjects, teachers, and departments.

Published: August 2022

Objectives This study was conducted to verify the effect of applying a psychonursing simulation program using standardized patients to nursing students.
Methods This is a single-group pre- and post-experimental design study conducted on 49 third-year nursing students. The research procedure consisted of the formation of a psychiatric nursing practice simulation team, program development, standardized patient selection and training, program application and effectiveness verification.
Results Learner self-efficacy(t=4.81, p<.001), learning satisfaction(t=3.95, p<.001), and transfer motivation(t=5.44, p< .001) were significantly improved compared to before the implementation of the program, and there was a quantitative correlation between learner self-efficacy, learning satisfaction, transfer motivation, and self-efficacy in communication.
Conclusions Since simulation education using standardized patients was useful in mental nursing practice education, it is expected to help improve the quality of mental nursing practice and clinical practice education.

We introduce Mitiq, a Python package for error mitigation on noisy quantum computers. Error mitigation techniques can reduce the impact of noise on near-term quantum computers with minimal overhead in quantum resources by relying on a mixture of quantum sampling and classical post-processing techniques. Mitiq is an extensible toolkit of different error mitigation methods, including zero-noise extrapolation, probabilistic error cancellation, and Clifford data regression. The library is designed to be compatible with generic backends and interfaces with different quantum software frameworks. We describe Mitiq using code snippets to demonstrate usage and discuss features and contribution guidelines. We present several examples demonstrating error mitigation on IBM and Rigetti superconducting quantum processors as well as on noisy simulators.
Notas sobre la fisiocracia en el mundo ilustrado: características, alcances y reflexiones en la sociedad del siglo XVIII
Authors: Mendoza Manotas María Angélica Del Mar
Published: August 2022

Las escuelas de pensamiento económico preclásico han sido una base fundamental para entender los procesos económicos a través del tiempo, así como la evolución de las teorías y postulados que la economía ha desarrollado desde su análisis e interpretación. La fisiocracia es una corriente liderada en su mayoría por franceses en el siglo XVIII, donde se instalaron unas bases propias de rentas y utilidades a partir de las actividades agrícolas. No obstante, durante este periodo Europa vivía grandes cambios a razón de la Ilustración y otros fenómenos asociados a la reestructuración social durante ese periodo. Este documento presenta un análisis de las características esenciales de la fisiocracia y el impacto frente a la formación y estructura de la Europa del siglo XVIIII. Las fuentes empleadas son secundarias para la interpretación y análisis de estos hechos dado el estudio y aportaciones de autores, con ello se buscará reflexionar en torno a esta corriente y su incidencia dentro de la trayectoria económica. Como principales resultados se evidencia la presencia de los modelos instalados a partir de los procesos productivos que sirvieron como base a las estructuras de comercio y las dinámicas de mercado agrícolas.
