Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Park Jung-in
Published: October 2024

Objectives The purpose of this study is to provide policy implications based on the implementation of the high school credit system in the field of special education in relation to the high school credit system that will be fully introduced from 2025.
Methods This study conducted a qualitative meta-analysis on eight qualitative studies conducted on special schools and special classes in general high schools that have been designated and operated as high school credit system research and leading schools.
Results First, it was confirmed that teachers, parents, and students agreed on the purpose and significance of in-troducing the high school credit system, but were negative about the curriculum, organization, and support sys-tem for those eligible for special education. Second, regarding the implementation of the high school credit sys-tem in the field of special education, education providers and education consumers proposed the establishment of specific systems and guidelines according to the type and characteristics of disabilities and the expansion of administrative and financial support. Third, while social awareness and environment regarding disabilities are changing, there appears to be a demand for a paradigm shift in career and vocational education for students eligi-ble for special education following the implementation of the high school credit system.
Conclusions Based on these results, the high school credit system curriculum, support system, and awareness in the special education curriculum that will be implemented from 2025 were discussed and future tasks were presented.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kwoon Junghyeon
Published: October 2024

Objectives This study is about the experience of a professor who started working as a new professor in the Department of Liberal Study at a local national university and was appointed as a new professor in the process of establishing and operating the department according to the university innovation promoted by the Ministry of Education and the university's own innovation process.
Methods We explored the process of being selected and appointed as a professor in the newly established Department of Liberal Study at a local national university located in Region J. While working as a new professor in the department, which is directly related to university innovation, I sought to express in-depth my experience in adjusting admissions units, establishing new educational units, consultation processes with university members, and operating new curricula. For this purpose, the autoethnography research method, which is a research method for one's own culture, was applied.
Results By conducting this study, the following five research topics were derived. ｢① Universities’ hot potato ‘Department of Liberal Study’｣, ｢② New professors at the Department of Liberal Study who lack even the basics｣, ｢③ Establishment of new educational units facing various obstacles｣, ｢④ Survival and growth, and the life of a professor moving forward with reflection｣, ｢⑤ Department of Liberal Study moving to the forefront of change and innovation｣
Conclusions Based on these research results, we described the difficulties and adaptation problems of new professors in Department of Liberal study in relation to the non-major admission system. And We discussed ways to advance toward growth and reflection in the university innovation process, which is directly related to the sustainability and survival of the department. This study is significant in that it is the first study to reveal the work experience of a new professor in the Department of Liberal Study, and suggested follow-up research in terms of research subjects and research methods.
English learning resilience of Korean students: Using explanatory sequential mixed methods
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kim Youngmi , Kim Tae-Young
Published: October 2024

Objectives This study aims to investigate the characteristics of English learning resilience among Korean learners by using explanatory sequential mixed methods.
Methods To this end, in the first stage, a five-point Likert scale questionnaire of four constructs (social support, satisfaction, persistence, and emotional regulation) measuring English learning resilience was administered to 180 students at a university in Seoul. In the second stage, reflective essays about their English learning at each school level were collected from 52 students at a university in Seoul. The average and standard deviation for each question were calculated from the questionnaire, and episodes related to each construct were analyzed through repeated reading.
Results The analysis on the questionnaire showed the scores for ‘satisfaction’ and ‘persistence’ were high among the four constructs. Qualitative analysis revealed that teachers' support and emotional control were found across the school levels. However, emotional recovery strategies and strategic flexibility appeared with higher frequency as the school level advances.
Conclusions This suggests that interventions to promote English learning resilience reflecting the characteristics of the school level are needed to help learners overcome the challenges in learning English.
Effects of Mathematics Instruction with Universal Design Learning and Evidence-Based Instruction on Multiplication and Division Performance and Mathematical Learning Attitudes of Elementary School Students
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Yoon Keumseol
Published: October 2024

Objectives The purposes of this study was to examine the effects of mathematics instruction, incorporate Universal Design for Learning(UDL) and evidence-based instruction, on the multiplication and division achievement and mathematical learning attitudes of 4th grade elementary school students with typical or low achievement in mathematics.
Methods The study involved 46 subjects, comprising students from two 4th-grade classes in a public elementary school in Seoul. The subjects were divided into experimental and control groups, with each group further subdivided based on their level of mathematics achievement. The experimental design employed a pretest-posttest control group design along with a repeated measures design. Improvements in students’ multiplication and division achievements were analyzed using a hierarchical linear growth model, while differences in attitudes towards mathematical learning were assessed using paired samples t-tests and analysis of covariance(ANCOVA).
Results First, the rate of change in multiplication and division achievement among students with typical math performance in the experimental group was statistically significantly higher than that in the control group. Second, the rate of change in multiplication and division achievement among students with low math performance in the experimental group was significantly higher than that in the control group. Third, within the experimental group, students with low math performance demonstrated a significantly greater rate of improvement in achievement compared to students with typical math performance. Fourth, students in the experimental group showed statistically significant improvement in most areas of mathematical learning attitudes. Finally, there was no statistically significant difference in mathematical learning attitudes between the two subgroups of the experimental group, except for their level of confidence in multiplication and division.
Conclusions First, mathematics instruction incorporating Universal Design for Learning (UDL) and evidencebased instruction was effective in improving multiplication and division achievement as well as mathematical learning attitudes among 4th grade elementary students. Finally, it can be inferred that this approach could be an effective method for ensuring foundational academic skills and bridging achievement gaps in general education settings with diverse student characteristics.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Lee Eun Ae , Chae Seon Ki
Published: October 2024

Objectives This study aimed to investigate the mediating effects of emotional clarity and self-compassion in the relationship between internalized shame and interpersonal problems among adults aged 18 and older.
Methods An online survey was conducted to measure internalized shame, interpersonal problems, emotional clarity, and self-compassion among adults aged 18 and older. A total of 443 participants (122 males and 321 females) were included in the analysis, which was performed using SPSS 29.0 and AMOS 26.0 statistical software.
Results First, internalized shame, interpersonal problems, emotional clarity, and self-compassion were all found to be significantly correlated. Second, emotional clarity mediated the relationship between internalized shame and interpersonal problems. However, self-compassion did not show a significant mediating effect in this relationship. Third, a dual mediation effect of both self-compassion and emotional clarity was observed in the relationship between internalized shame and interpersonal problems.
Conclusions The findings suggest that when adult clients report interpersonal problems, it is crucial to consider internalized shame and focus interventions on emotional clarity and self-compassion. Finally, the implications and limitations of this study are discussed.

Korean University Students’ Perceptions of English Idioms
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Park Hyechong
Published: October 2024

Objectives This study investigates the psychological language distance regarding types of English idioms among Korean undergraduate students to elucidate the mechanisms of language transfer, hypothesizing that the perception of semantic similarity between Korean and English idioms leads to positive transfer.
Methods A total of 82 undergraduate students in a metropolitan city participated in a questionnaire study that categorized English idioms based on semantic and formal similarity between Korean and English. The validity of findings regarding language transfer is enhanced when data on psychological perception, reflecting the process of language transfer, corroborates comprehension data, indicating the outcome of language transfer. In the questionnaire, therefore, the participants' psychological perceptions of the ease and difficulty of English idioms were measured using a Likert scale, and their comprehension of English idioms was assessed using a multiple-choice format. In addition, since idioms with prior knowledge are automatically processed and language transfer does not work, participants were asked to mark the items that they had prior knowledge of to exclude them from the data analysis.
Results Korean students' perceived ease with English idioms was in the order of cognate idioms > pragmatic idioms > L2-only idioms > false friends idioms, while the accuracy rates of idiom comprehension were ranked as cognate idioms > pragmatic idioms > false friends idioms > L2-only idioms. The results showed that semantically similar idioms (i.e., cognate idioms, pragmatic idioms) were perceived as easier and had higher accuracy rates compared to dissimilar idioms (i.e., L2-only idioms, false friends idioms), supporting the Contrastive Analysis Hypothesis concerning transfer of meaning. However, psychological perception and accuracy rate data for dissimilar idioms produced conflicting results regarding psychological language distance. Nevertheless, pragmatic idioms with similar meanings but different forms between Korean and English were perceived as easier and had higher accuracy than false friends idioms with different meanings but similar forms. This suggests that the perception of cross-linguistic semantic similarity, rather than formal similarity, triggers positive transfer.
Conclusions This study confirms the Psychotypology Hypothesis proposed by Kellerman (1983), which posits that perceived cross-linguistic similarity leads to language transfer, as supported by corroborative evidence from psychological perception and accuracy rate data. However, conflicting findings within dissimilar idioms suggest the need for follow-up studies employing various methods to measure psychological language distance, thereby validating the reality of language transfer more robustly.

SOVIET-BULGARIAN MILITARY COOPERATION AT THE FINAL STAGE OF THE GREAT PATRIOTIC WAR
Authors:   The Institute of General History of the Russian Academy of Sciences (Russia), Kondratenko S.Yu.
Published: October 2024

The article reveals the features of Soviet-Bulgarian military cooperation in the last months of the Great Patriotic War. In September 1944, the government of the Fatherland Front came to power in Bulgaria, which broke off relations with Nazi Germany and went over to the side of the Anti-Hitler coalition. The Soviet military-political leadership was interested in the participation of Bulgarian troops in hostilities against Germany and as soon as possible began to establish military cooperation with the new Bulgarian government. Cooperation between the two countries in the military field had a number of significant features that were taken into account by both sides when making decisions. In the fall of 1944, the Soviet command planned to quickly involve Bulgarian troops in combat operations in Yugoslavia, so it sought to limit the scale of military reforms of the Fatherland Front government. After the liberation of most of Yugoslavia, it was decided to limit the participation of Bulgarian troops in hostilities, which contributed to the deployment of a large-scale reorganization of the Bulgarian armed forces with logistical and organizational assistance from the Red Army.
«MODUS VIVENDI» OF GERMAN SHIPBUILDING COMPANIES IN THE RECEIPT OF RUSSIAN MILITARY ORDERS AT THE BEGINNING OF THE 20th CENTURY
Authors:   University of Tyumen, (Tyumen, Russia), Sinegubov S.N. , Shilov S.P. , Zavorokhina N.S.
Published: October 2024

The article is devoted to considering the issue of using complex tools for obtaining profitable orders from the Russian authorities by German shipbuilding companies, and primarily by the Schichau company. First of all, legal “gaps” in the Russian legislation of the early 20th century (which generally protected and stimulated the development of domestic military shipbuilding) were very skillfully used by the Germans. Based on an analysis of original and published German and Russian archival materials, published memoirs, as well as research literature, the authors came to a number of conclusions. Formally, already from the second half of the 90-ies of the 19th century there existed legal norms that outwardly protected and strengthened Russian shipbuilding. At the beginning of the 20th century they were supplemented by decisions of the Committee of Ministers and then the Council of Ministers, respectively, in 1901, 1902 and 1907, which, however, did not work perfectly. The main reason for such a state of affairs was the de facto and de jure deviations from the prescribed rules. The authors consider another significant motivating factor for this process: the “price rush” of Russian shipyards for their products and, on the contrary, the “soft dumping” of German manufacturers and their strict adherence to deadlines for fulfilling their obligations. The political calculations of official authorities in St. Petersburg and the corruption of Russian authority representatives played a certain role as well.
LABOR LEGISLATION IN RUSSIA AND GREAT BRITAIN IN THE LATE 19TH - EARLY 20TH CENTURIES: COMMON AND DIFFERENT FEATURES (ON THE EXAMPLE OF CHILD LABOR LAWS)
Authors:   Orel State Institute of Culture (Russia), Stepanova V.V.
Published: October 2024

The focus of this study is labor legislation in Russia and Great Britain. The period of the late XIX - early XX centuries became a time of transition of new labor standards, which had both positive and negative consequences for the working class, but at the same time reflected interests of big capital. The laws discussed in the article (the Russian law «On minors working in factories, factories and manufactories», the English law «Factory and Workshop Act 1878» and others) haven’t only historical, but also social significance, since they raise important issues of ensuring rights of children and young people, and also lay the foundation for the further development of legislative initiatives. The development of the legislative framework on child labor in England begins somewhat earlier than in Russia. However, further changes made to the regulatory framework of the two countries have a general tendency to increase the age threshold for children’s involvement in labor activity and the requirements for primary education. At the same time, the legislations of these countries also have common problems associated with numerous exceptions for the use of child labor in production. The author of the article proposes a new approach to the analysis of comparative aspects of the legislation of Great Britain and Russia, which will allow us to identify and generalize the factors and conditions that shaped the labor legal environment during the transition period. The results of this article contribute to a better understanding of the processes that underlie the development of modern labor law and can be used for further research in the field of labor law in the 21st century.
THE 2007 ANNAPOLIS CONFERENCE: UNREALIZED POTENTIAL
Authors:   Moscow State Institute of International Relations (University), Ministry of Foreign Affairs of Russia, Abdullayev H.P.
Published: October 2024

The Annapolis Conference plays an important role in the study of the evolution of the Palestinian-Israeli conflict and peace efforts in the Middle East. The relevance of the study is due to the significant impact of the 2007 conference on the course of the peace process in the region, as well as the failure to fulfill its main goals. The study aims to analyze the reasons why the Annapolis Conference failed to achieve its key objectives, thereby highlighting the broader problems of peaceful settlement in the region. The purpose of this study is to gain a deep understanding of the factors that hindered the successful peaceful dialogue and the fulfillment of the commitments made at the conference. The research methodology, based on historical and systematic approaches, includes an analysis of historical documents, political context, as well as international relations and their impact on the peace process. An important aspect of the research is to study the role of key participating States, including the United States and the countries of the Middle East, in the dynamics of negotiations. The results of the study show that the main obstacles to the success of the Annapolis Conference were political instability in the region, inconsistency between the parties to the conflict, as well as insufficient support from the international community. The key conclusions are the need for a deeper understanding of the international dynamics of the conflict, as well as the development of more effective strategies to ensure long-term peace in the region.
RUSSIA'S SMO ON UKRAINE IN THE PUBLICATIONS OF THINK TANKS IN SUB-SAHARAN AFRICA
Authors:   Moscow State Institute of International Relations (University), Ministry of Foreign Affairs of Russia, Anfaylov O.S. , Loshkariov I.D.
Published: October 2024

The article analyses the publications of three key think tanks in Sub-Saharan Africa on the causes, consequences, global and regional context of the Ukrainian conflict, as well as its impact on African countries and their political course. The authors examine the publications of think tanks that can influence foreign policy decision-making in African states in order to assess the potential for changing their position on the Russian SMO, as well as the dominant perceptions in the African expert community about the impact of the Ukrainian conflict on international relations. In their publications, the think tanks focus on three key topics: the global context of the Ukrainian conflict and its implications for world politics, the impact of the Ukrainian conflict on the situation in Africa, and the position of some Sub-Saharan African countries on the Ukrainian conflict. African experts see the Ukrainian conflict as a manifestation of great-power competition and see it as a starting point for future changes in the world order. At the same time, they clearly see its negative consequences for the economic situation in African countries.
THE STATUS OF A. DEMIDOV’S MINING COMPLEX IN ALTAI IN THE ADMINISTRATIVE LEGAL FRAMEWORK OF SIBERIA IN THE SECOND QUARTER OF THE XVIII CENTURY
Authors:   The National History Department of Altai State University (Barnaul, Russia), Bobrov D.S.
Published: October 2024

Russia's transition to the early Imperial state model in the first quarter of the XVIII century required qualitative changes in the management model, for example realization of departmental and sectoral distinctions, incorporating of large private economic units in the regional and national structure. The purpose of the article is to analyze the formation and key parameters of the status of the Kolyvan-Voskresensk plants (Kolyvan-Voskresensk mining department) in the administrative legal system of Siberia during the period, when the industrial complex belonged to A. Demidov. The research was based on the materials of the collections of the Russian State Archive of Ancient Documents and the State Archive of the Sverdlovsk Region, as well as some published documents. The author shows that the formation of the Demidov’s industrial district in Altai at the initial stage the level and nature of the realization of institutional and functional distinctions did not allow to completely overcome the legal unsettled situation in this area. Most of the critical problem of intersectoral cooperation in relation to the Kolyvan-Voskresensky plants were regulated in the early 1730s. The civil authorities made attempts to covertly resist the strengthening of the influence of A. Demidov's private ownership structures and his mining complex in the administrative system of Siberia in second quarter of XVIIIth century.
THE DEVELOPMENT OF THE CONCEPT OF «SOCIALIST RECONSTRUCTION» OF SARATOV IN THE MASTER PLANS OF THE 1930S – EARLY 1950S.
Authors:   Saratov State University (Russia), Vanin A.A.
Published: October 2024

The article discusses the process of development of urban planning in Saratov during the reign of I.V. Stalin. The problems of development of urban space that faced the city planners of Saratov at that time, the general plans of the city and their variants developed in the 1930s - early 1950s, as well as the factors that influenced the process of their development are analyzed. The study is based on the use of a set of methodological techniques, including such special methods of historical science as historical-genetic and problem-chronological, as well as an interdisciplinary approach, in particular, the methods of urban studies and semiotics. The current development of the city strongly contradicted the city planning plans, which entailed constant and very significant adjustments in design development throughout the entire period of the 1930s - early 1950s. In addition, constant changes in project documentation were also caused by some adjustments in the plans for major construction projects of all-Union significance, such as the construction of hydroelectric power stations. However, despite the fact that the master plans were constantly cut back, the scale of these developments remained quite large. All of them rather weakly correlated with the real economic situation and opportunities of the city and, paradoxically, with the economic and political priorities of the state as a whole. The implementation of these plans was started, however, under the conditions of the extensive development of the Soviet economy in the first five-year plans, and then in the difficult conditions of the war and post-war years, and with the low level of development of the construction industry, it could not take place in full.
THE REPRESSIVE PRACTICE OF STALINISM IN THE STUDIES OF SMOLENSK HISTORIANS
Authors:   Smolensk State University (Russia), Kodin E.V. , Graf Ya.Yu.
Published: October 2024

The article discusses the process of forming a research direction for the study of the repressive practice of Stalinism in the Smolensk region. It is noted that for historians, repressions became an object of study only in the 1990s, when it became possible to work with archival materials. Access to the archives and the opportunity to get acquainted with various methodological approaches to the problems of repressions allowed Smolensk researchers to take up the development of certain areas of the repressive practice of Stalinism in the region. Initially, O.V. Kobets and R.V. Shamshin analyzed the practice of collective farm construction and dekulakization in the Smolensk region, identifying the reasons for the insignificance of peasant resistance to state policy in the village at the turn of the 1920s-1930s. Makeev, having gained access to the documents of the archive of the FSB in the Smolensk region, showed the activities of the prosecutor's office and the court for the consideration of criminal cases of counter-revolutionary crimes in 1937-1938. In the works of O.V. Kornilova, the theme of the GULAG was developed on the example of the Vyazemlag for the construction of the Moscow-Minsk highway. The most significant result of the long-term work of Smolensk historians on the repressive practice of Stalinism in the region was the formation and publication of the multi-volume Smolensk martyrology "Book of Memory of Victims of Political Repressions" and the creation on its basis of an electronic file of victims of political repressions for 1917-1953.

Published: October 2024

The second part of the paper presents the results of uniaxial tension testing of smooth round bars of 2Cr–Ni–Mo–V steel in the thermally-embrittled state and St3 steel in the initial state. SEM examination of the fracture surfaces is carried out. The brittle fracture probability is calculated using the Prometey model presented in the first part of this article. It has been found that the plastic strain effect on the microcrack propagation probability is caused by two reasons: (1) the critical brittle fracture stress increase due to formation of new barriers for microcrack under plastic deformation, and (2) the working volume decrease due to the neck formation in tensile round bar. A unified set of parameters has been proposed to take into account the plastic strain effect on cleavage microcracks propagation probability for WWER-1000 RPV steel and low-alloyed low-strength steel.
Influence of highly dispersed phase of titanium carbide on physical and mechanical properties of alloys AM4.5Kd and AK10M2N
Authors: Sherina Yu. V. , Luts A. R. , Minakov E. A.
Published: October 2024

Dispersion-strengthened composite materials belong to the group of promising structural materials characterized by a diverse combination of properties. The work presents examples of the creation and heat treatment of composite materials based on aluminum alloys, strengthened by a dispersed phase of titanium carbide, and characterized by high hardness, elastic modulus and good wettability by the melt. The most accessible, inexpensive and effective way to obtain them is self-propagating high-temperature synthesis (SHS).

The work shows the possibility of obtaining new aluminum matrix composite materials based on industrial aluminum alloys AM4.5Kd and AK10M2N by reinforcing them with 10 wt.% highly dispersed titanium carbide or AM4.5Kd–5.95 vol.% TiC and AK10M2N–5.78 vol.% TiC. The reinforcing phase is formed in alloy melts using the technology of SHS from the initial elemental components—titanium powder and carbon black. Using the obtained samples, an assessment was made of the uniformity of the ceramic phase distribution over the volume of the matrix alloys, which amounted to 0.15 and 0.12 for the samples AM4.5Kd–10%TiC and AK10M2N–10%TiC, respectively, which constitutes a high degree of uniformity.

An assessment was made of physical properties such as porosity, density, electrical conductivity, as well as the coefficient of thermal linear expansion. Analysis of the data allows us to say that the final composite materials AM4.5Kd–10%TiC and AK10M2N–10%TiC have a slightly higher density (↑~4%) than the matrix alloys, due to the presence of a ceramic phase, low porosity values (~1%), lower TCLE (↓~6%) than matrix alloys and low electrical conductivity (~25% IACS). This article also presents data on the values of the mechanical properties of composite materials AM4.5Kd–10%TiC and AK10M2N–10%TiC. It has been shown that reinforcement with a ceramic phase contributes to a significant increase in hardness by 15 and 42 HB, as well as higher values of the compressive yield strength by 31 and 17 MPa, respectively, while maintaining a high level of relative deformation. The results obtained allow us to conclude that the developed composite materials can be recommended for products used under conditions of elevated temperatures and significant wear.

The results of plastic compression of steels and alloys of different chemical compositions at temperatures and rates of plastic deformation corresponding to common thermomechanical treatment (TMT) regimes are considered. The features of the diagrams σ (ε, έ, Т) are revealed. The processes of strain accumulation and thermal dissipation are accompanied by structural rearrangements. Depending on the chemical composition and hot compression modes, structural transformations occur self-organized, with the possibility of excitation of oscillations and the formation of dissipative solitons.
Balancing Cost and Environmental Impact: A Linear Programming Approach to Sustainable Shopping
Authors: Tüsün Sapan Beyhan Seren , Paç Ahmed Burak
Published: October 2024

A linear programming model is devised for consumer purchasing decisions minimizing weighted cost and environmental impact using real-world data.  Minor shifts towards environmental preferences can greatly reduce impact with minimal cost increase. Spending slightly more on the bundle than the cheapest option can cut environmental impact by a third. Conversely, less than 10% compromise in impact yields over 15% cost savings. Consumers can find efficient midpoints—cost-effective and environmentally sustainable options—through strategic decisions. Additionally, a synthetic dataset, modeling different societal dispositions through Beta distributions of cost-environment orientation parameters, simulates societal attitudes, showing that a 10% reduction in environmental impact is possible with a 23% higher economic burden, while 60% of this reduction can be achieved with only 3.1% increase in cost when maintaining a balanced societal disposition.  This demonstrates the potential of optimization-based strategic purchasing decisions to achieve significant economic and environmental efficiencies when accompanied by increased environmental awareness.

Published: October 2024

Background: Povidone-iodine (PVP-I) is an antiseptic that is commonly used as an alternative to alcohol in clinical settings, including for perioperative skin disinfection. However, the presence of iodine in PVP-I can result it adverse effects on thyroid function. This study explored the effect of PVP-I on thyroid function and assessed its safety profile.Methods: We assessed thyroid function in patients before and after treatment with Repigel (topical liposomal hydrogel with 3% PVP-I) between January 2017 and January 2023, for a period of at least 2 weeks. Patients were stratified by age, sex, and previous history.Results: No significant changes in thyroid function were observed in the 61 patients enrolled until 2 weeks after application of Repigel. Significant increases in T3, T4, and free T4 levels were detected 4 weeks after Repigel application. A comparison of the initial thyroid function test (TFT) and TFT 4 weeks post-application found that the mean T3 levels were 71.12 ± 17.55 ng/dL and 59.84 ± 18.60 ng/dL and mean T4 levels were 6.48 ± 1.49 µg/dL and 5.50 ± 1.36 µg/dL, respectively. The mean free T4 levels were 1.08 ± 0.39 ng/dL and 0.90 ± 0.19 ng/dL, respectively.Conclusion: Changes in thyroid function during the application of Repigel were observed. We conclude that thyroid function should be examined at regular intervals before and after topical application of Repigel. Additionally, clinicians should exercise caution when administering iodine-containing substances such as Repigel to patients with abnormal thyroid function, and schedule follow-up TFTs at 4 weeks.
Las prácticas preprofesionales en la formación psicopedagógica ¿Revisión, supervisión o covisión?
Authors: Barilá María Inés
Published: October 2024

This paper arises from a research that aims to build knowledge about learning experiences, paths, and psychopedagogical interventions in pre-professional training practices. The strategy to approach the study is the open qualitative interview, administered to students and graduates, to analyze a category constructed from the repeated reading of the field records: Pre-professional practices in psychopedagogical training, with emphasis on the sub-axis referring to the accompaniment and the possibilities of reviewing these practices. Focusing on practices means addressing complex events that confront students with decisions characterized by the uniqueness of their journeys. Follow-up and accompaniment require a space to listen to obstacles, advances, and setbacks, failed and accurate interventions: the review -supervision or co-vision- of the psychopedagogical practices that are carried out individually or in groups in the context of institutions.
