Authors: Ulfah Silfiyah , Zainudin Agus , Septia Erfan Dani
Published: October 2024

This study aims to obtain information on changes in the character of individual M2 generation mutant rice, similarities between individuals of the M2 generation mutant and its comparison, and correlation between variables. This research was conducted by observing the vegetative, generative, and potential yields of each individual rice mutant and its comparison. The data obtained were tested by cluster analysis and correlation analysis. The observations showed that almost all the characters of the M2 generation mutant individuals changed except for the qualitative vegetative characters. Cluster analysis based on quantitative vegetative character showed 1 different mutant individual (0% similarity), and 1 other individual with 38.83% similarity compared to other and non-mutant mutants, and commercial varieties. Based on quantitative and production generative characters, there are 2 distinct groups that differ from each other (0% similarity). The similarity range of each distinct group is 21.17-43.56%. The strong to very strong and very significant correlation that occurs in vegetative and generative characters with production is found between the number of tillers and panicles, total grain weight and dry grain weight of 98.7% each; 60.9% and 58.3%; the number of leaves is thus also between the number of panicles, total grain weight and dry grain weight respectively 91.3%; 53.3% and 53.4%; panicles with total grain weight and dry grain weight were 60.1% and 57.6%, respectively.

The main commodity of food crops is rice which has a strategic function, namely as a staple food for the people of Indonesia. Maintaining the health and quality of soil biologically by reducing dependence on synthetic fertilizers. Swamp Inbred Paddy (Inpara) are superior varieties of paddy that are well cultivated in swamp land conditions, resistant to immersion, and adaptability to acidic soil conditions. This study investigates the combination of biological and synthetic fertilizers on the growth of flood-tolerant Inpara rice using a strip plot/split block design. The treatments used were 6 combinations of biological fertilizers-synthetic fertilizers and 3 paddy varieties with 3 replications. The results obtained from the analysis of variance then conducted a further test of BNJ to determine the performance of each variable. Correlation test is performed to determine the interactions and relationships between observational variables. Soil analysis is also carried out to determine the mineral content in the soil. The effect of the combination of synthetic and biological fertilizer doses with 3 Inpara paddy varieties interacted significantly on several observational variables resulting in significantly different performance. The combination treatment with 75% synthetic fertilizer and 25% biological fertilizer showed several parameters that were higher than the treatment with 100% synthetic fertilizer so that the use of synthetic fertilizer can be reduced.
Participating—or Being Part of an Organizational Change: Narratives of Participation Related to School Closures to Reduce School Segregation
Authors: Flensner Karin K. , Svensson Ylva
Published: October 2024

The mission of all primary schools includes offering all pupils educational quality and equality. Municipalities struggle with the negative consequences of school segregation, and some local councils decide to implement extensive changes in their school organization to offer all pupils equal opportunities. This study analyzes the experiences of staff and students when a local council implemented organizational changes to reduce the negative consequences of school segregation. A narrative analysis of documentation from the education authority and interviews with pupils and school staff were used to understand the perspectives of staff and pupils. There was strong support from the staff for implementing the changes but also strong criticism of how these changes were carried out. One conclusion is that municipalities implementing similar changes need to plan for the whole process and the participation of pupils and school staff in a systematic way.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Yoon Pan-Ki , Hwang Hye-Jeong
Published: October 2024

Objectives This study was to determine the effect of interpersonal trauma experience in childhood on post-traumatic growth in adults.
Methods 266 adult men and women aged 20 to 59 in Korea were surveyed and analyzed through an Internet questionnaire. The research tool was the Korean version of childhood trauma. It was a questionnaire (Eun-jung Kim, Jin-sook Kim, 2010) and a post-traumatic growth scale (Si-hyung Kim et al., 2020). For the data, skewness and kurtosis were analyzed using the SPSS 22.0 statistical program to confirm whether the assumption of normality was satisfied, and correlation analysis and t-test for differences between major variables, One-way analysis of variance and hierarchical regression analysis were performed.
Results First, as a result of verifying the difference in post-traumatic growth according to the background variable, men were significantly higher than women in all post-traumatic growth according to gender. According to marital status, married people were significantly higher than unmarried. Depending on the age, those in their 50s were significantly higher than those in their 40s, 30s, and 20s. In addition, the difference in overall post-traumatic growth was significant according to the type of interpersonal trauma experience in childhood, sexual abuse, physical abuse, neglect, double abuse, and emotional abuse appeared in order. In addition, there was no difference in the factors of trauma perpetrator between trauma period, caregiver, and childhood interpersonal relations. Second, as a result of the correlation analysis of the main variables, it was found that there was no significant correlation between the entire childhood trauma and the entire post-traumatic growth. However, among the sub-factors, emotional neglect and post-traumatic growth were negatively correlated, and sexual abuse and physical abuse were positively correlated with post-traumatic growth. In other words, the higher the emotional neglect, the lower the post-traumatic growth, and the higher the sexual and physical abuse, the higher the post-traumatic growth. Third, it was found that interpersonal trauma experience in childhood had a significant effect on post-traumatic growth. Emotional abuse during childhood trauma was static and emotional neglect was negative. It was found to have an effect. In other words, the higher the emotional abuse among childhood trauma experiences, the more post-traumatic growth. It can be interpreted that the higher the emotional neglect, the lower the likelihood of post-traumatic growth.
Conclusions The results suggest that lowering emotional neglect is effective to increase post-traumatic growth.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Eom Yoogyung
Published: October 2024

Objectives The purpose of this study is to categorize convergence education practice methods into six types and analyze the perceptions and needs of undergraduate students at S University regarding these methods.
Methods To achieve the research purpose, the researcher classified convergence education practice methods in-to six types through literature review. Based on them, the needs analysis was conducted through the ques-tionnaire targeting the undergraduate students at S University. For the analysis, the t-test, Borich need assess-ment model, and Hershkowitz's criticality function were used.
Results Among the methods of implementing convergence education, the methods that S University under-graduate students recognize as most important were identified in the order of AI liberal arts curriculum expansion, teaching and learning innovation, and student-designed majors. Among these, regarding the operation of the stu-dent-designed major system, the current implementation level of S University was recognized as higher than the level of importance. As a result of calculating the Borich demand value, it was confirmed that the following order was innovation in teaching and learning, system for allowing major changes without division, and innovation in major curriculum content. By synthesizing the results of Hershkowitz's critical function analysis, the practice of convergence education through innovation in the teaching-learning area had the highest level of demand from S University undergraduate students.
Conclusions Based on the results of this study, first, in order to practice convergence education in university set-tings, it is important to introduce educational content and curriculum that break down the boundaries between majors, but it is also necessary to discuss educational methods to put this into practice. Second, It was suggested that strengthening the capacity of instructors to practice convergence education is also important, and thirdly, that an administrative and financial support system suitable for each university's situation to practice convergence ed-ucation should be established.
Research on creating animated materials to promote math learning: Based on the Python library Manim
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kim Hye Su , Jeon Young Ju
Published: October 2024

Objectives The purpose of this study is to propose guidelines for producing animation materials as a way to help students understand the characteristics of mathematics and mathematical concepts and principles, and to in-troduce Manim, an effective mathematics animation material production tool.
Methods We investigated animation production principles that can be helpful in the math animation production process, and applied them to already produced math animation materials to find out their suitability as math ani-mation production principles. In addition, the scope of GeoGebra's animation implementation functions, which are used in the production of mathematical materials, was confirmed, and the possibilities of supplementing the limi-tations of various functions revealed here were explored through Manim. and we looked at the process of produc-ing animation materials using Manim and the results.
Results As a result of analyzing whether the animation production principles adopted and applied are valid for the production of mathematics animation materials, we found some requirements that should be modified and sup-plemented from the perspective of mathematics education, and derived improved guidelines for the production of mathematics animation materials. GeoGebra, one of the production tools, has an animation composition func-tion, but there were limitations in its implementation functions, such as setting text condition input and repeating the target hiding operation. In comparison, although Manim requires an understanding of basic Python grammar, it was found to have great advantages in producing mathematical animation materials, such as intuitive com-mands, convenient property change function, free expression ordering, and various animation effects.
Conclusions Previous animation production research has not sufficiently considered the abstract nature of math concepts. accordingly, the need for improved guidelines that cover the expression of mathematical concepts, and the use of formulas as the main object of animation has emerged. GeoGebra has limitations in its animation com-position function, so the need for it is increasing along with the expansion of new mathematical animation material creation tools that go beyond that function. accordingly, it was confirmed that Manim, which uses simple com-mands as an alternative production tool, is a very specialized tool for creating mathematical animations.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Bang Seon-Kyeong
Published: October 2024

Objectives The present study aimed to examine the relationship between irrational beliefs (demandingness, cat-astrophizing, low frustration tolerance, and self-downing) and depression and the mediating effect of negative automatic thoughts on the relationship between them.
Methods We conducted an online survey of 464 adult men and women (205 males and 2,259 females) and used structural equation modeling analysis to examine whether catastrophizing, low frustration tolerance, and self-deprecation sequentially mediate the relationship between demandingness and depression through negative automatic thoughts .
Results The findings are as follows: First, demandingness had a positive effect on catastrophizing, low frustration tolerance, and self-downing. Second, the relationship between demandingness and depression was fully medi-ated by low frustration tolerance and negative automatic thoughts sequentially. Third, the relationship between demandingness and depression was sequentially fully mediated by self-downing and negative automatic thoughts. Fourth, catastrophizing and negative automatic thoughts did not sequentially mediate the relationship between emandingness and depression.
Conclusions Based on these findings, we discuss the significance of the present study, psychotherapeutic im-plications for effective interventions with clients who complain of depression due to irrational beliefs, and sugges-tions for future research.
A Study on Changes of Teacher’s in Early Child care in the Viewpoints on Kid Plays by Reviewing the Play Records
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, You Ji-Hye , Oh Chai-Sun
Published: October 2024

Objectives The research objectives of this study is to find out the reflection that the researcher as kindergarten early- child care teacher has, in the course of reviewing the individual play records, and changes in the viewpoints of teachers in early-child care on kid plays.
Methods In order to achieve this goal, self-study among qualitative research methods is conducted in that one can re-see and reflect on one's beliefs, values, and play records through self-reflection. To achieve such ob-jectives, the researcher collected and analyzed the play records that were prepared through author's own ob-servation in class, the author's self-reflection journal, and any other materials.
Results This research has classified changes in the viewpoints of teachers in early-child care on kid plays into six sub-factors, say, understanding kids from a new perspective, expanding and supporting kid plays, participating in plays from a spectator to a player, reestablishing the educational belief system of teachers in early-child care as a supporter, connecting the curriculum in plays, and learning outside. For the final factors as to it, this study has classified into three top factors, namely, understanding plays from the perspective of kids, reestablishing the edu-cational belief system teachers in early-child care, and the operation of play-centered curriculum.
Conclusions By reviewing the play records, it was found that changes in the viewpoints of teachers in early-child care on kid plays brought about the significant change in actual kid plays. Given the research results, the play records that are being prepared in the current educational field would be instrumental. It is anticipated that this would con-tribute to implementing the kid play-centered curriculum which requires reinforcing plays, with the focus on kids.
Qualitative Study on the clinical Practicum, Supervision, and Undergraduate Experiences of Art Therapy Majors
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Park Yun-Mi , Jeon Su-kyung
Published: October 2024

Objectives The purpose of this study is to explore through qualitative research the experiences of undergraduate students majoring in art therapy in clinical practice, supervision, and undergraduate courses, and to analyze the intrinsic meaning of these experiences.
Methods Data were collected through two in-depth interviews with six undergraduate students majoring in alco-hol treatment. The interviews used a semi-structured questionnaire to encourage undergraduate students to talk freely about their experiences in clinical practice, supervision, and undergraduate courses. The collected data were analyzed using open coding according to qualitative research methodology, and themes were derived inductively. Through this, the main themes and subcategories experienced by the participants were identified and the research results were derived.
Results As a result of the analysis, 6 main areas, 14 categories, and 37 subcategories were derived. In clinical practice, external factors such as conditions of the practice institution, workload, communication between thera-pists, and changes in clients, and internal factors such as self-criticism, tension while performing roles, and sense of accomplishment after practice were identified. The supervision experience consisted of process aspects such as close supervision and shared experiences with colleagues, as well as academic and emotional support from the supervisor. During the bachelor's course, self-exploration, anxiety and burden about art work, and interaction with classmates served as factors that promoted improved future vision and psychological growth.
Conclusions These findings provide significant implications for establishing criteria for selecting clinical practice institutions, improving supervision education, and enhancing the role of school education in undergraduate pro-grams aimed at training art therapists.
A Study on Understanding the Title of Newspaper by Chinese Learners: Focusing on the vocabulary knowledge of advanced learners
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, LI CHUN
Published: October 2024

Objectives The purpose of this study is to measure how vocabulary knowledge(both quantitative and qualitative) affects Chinese advanced learners when they understand the newspaper title.
Methods To this end, a preliminary experiment was first conducted with four advanced learners (2 at Level 5 and 2 at Level 6). The preliminary experiment was used to address any ambiguities in the test materials and to adjust the number and order of the presented items. Based on the results of the preliminary experiment, a formal experi-ment was carried out with 60 advanced Chinese learners, divided into two phases: the first phase and a second phase involving post-experiment interviews. Additionally, this study conducted a statistical analysis of the col-lected data using SPSS 24.0, employing independent sample t-tests and paired sample t-tests.
Results As a result, since advanced learners already have a certain quantitative vocabulary knowledge, there is little obstacle to understanding the title of newspaper without specific vocabulary. Conversely, it was found that a lack of qualitative vocabulary knowledge made it difficult to understand the title of newspaper with specific vocabulary. In particular, in the case of ‘vocabulary with figurative meaning’ and ‘the idiomatic phrases’ of the newspaper title, it was found that learners had more difficulty understanding the newspaper title.
Conclusions Therefore, in order to improve the skilled vocabulary and practical vocabulary use of foreign learners, it is necessary to devise educational methods for these vocabulary in the future.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Park Ga-hee , Kim Eun-Kyung
Published: October 2024

Objectives This study aimed to determine the variation in the level of awareness and knowledge of young children with atopic dermatitis in kindergarten and nursery teachers and give basic data to support preschoolers in a healthy living environment.
Methods A survey was conducted in 250 incumbent teachers at early childhood education centers in Seoul and Gyeonggi Province; then, with the exception of insincerely completed questionnaires, 226 copies went through frequency analysis, t-test, and one-way ANOVA using an SPSS 26.0 program.
Results The main results of this study are as follows: First, both kindergarten and nursery teachers were poorly aware of young children with atopic dermatitis; both types of centers had homeroom teachers mostly take charge of guidance and management of young children with atopic dermatitis and generally accepted their parents' needs and wanted them to be trained and supported by external professionals. Second, kindergarten teachers had a be-low-average level of knowledge of young children with atopic dermatitis and an above-average level of relevant management. For nursery teachers, the knowledge was at the above-average level and the management was at a high level. Third, as for the differences in the level of knowledge and management of young children with atopic dermatitis between kindergarten and nursery teachers, both variables were at a higher level for the latter.
Conclusions It is necessary to expand the target population of research into kindergarten-related infrastructures as well as nurseries and give teacher education about atopic dermatitis in diverse ways so that young children with atopic dermatitis can get positive support in a healthier environment.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, ZHENG DAIRAN , WU ZIYING
Published: October 2024

Objectives This study aimed to analyze the realization patterns of interpersonal functions in dialogues of inter-mediate Korean language textbooks from the perspective of Systemic Functional Linguistics.
Methods This study analyzed the interpersonal functions and their realization patterns in dialogues from Korean intermediate integrated textbooks published in the late 2000s. By establishing two main analytical categories—mood system and mood metaphor—and conducting distribution and realization pattern analyses for each cat-egory, we explored the linguistic characteristics of textbook dialogues from the perspective of Systemic Functional Linguistics.
Results In the textbook dialogues, declarative sentences were most frequent, followed by interrogative, imper-ative, and suggestive sentences. For honorific forms, the combination of ‘하십시오체+해요체’ was most common, followed by ‘해라체+해체’, with the ‘하게체’ being least frequent. For mood metaphors, interrogative forms func-tioning as statements or commands were most frequently observed.
Conclusions The study confirmed that the analyzed Korean textbook dialogues accurately reflect the language us-age patterns of native Korean speakers, and demonstrated the effectiveness of the Systemic Functional Linguistics approach in textbook analysis.
A study of private tuition inequality: focusing on the private tuition Gini coefficient, the Hoover index and the Palma ratio
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Park Kyungmee , Kim Hwa Kyung
Published: October 2024

Objectives This study aims to find a way to measure the degree of inequality in private education expenditures in Korea and to analyze trends in inequality.
Methods We analyzed the private education expenditures survey conducted by the Ministry of Education to find an index that indicates the inequality of private education expenditures, and obtained each index by year to under-stand the trend.
Results The average private education expenditures per person is increasing, and the analysis of private education expenditures inequality using the Gini coefficient, the Hoover index, and the Palma ratio shows that inequality is increasing, especially in elementary schools. In 2020, during the COVID-19 situation, the private education Gini coefficient increased rapidly as the private education participation rate decreased in elementary and middle schools, but this phenomenon was not found in high schools.
Conclusions The Gini coefficient, Hoover index, and Palma ratio, which indicate the degree of inequality in private education, can be obtained for the entire population and participants, but considering that the case where private education expenditures are 0 has a significant impact, it may be more appropriate to limit it to participants. The Gini coefficient, which indicates income inequality, is on the decline, but the Gini coefficient for private education expenditures for participants is increasing, and since private education is linked to the problems of low birth rate and local extinction that our society faces, special measures are needed to reduce private education.

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

Objectives The purpose of this study is to empirically analyze the growth mindset related to learning outcomes of adult learners participating in lifelong education programs, the structural relationship between self-directed learning ability, and the partial mediating effect of self-directed learning ability in the relationship between growth mindset and learning outcomes.
Methods In order to solve the research purpose and research problem, 308 adult learners who are taking lifelong education program in university located in G city of Gyeongsangbuk-do were selected as research subjects. A sur-vey was conducted by selecting growth mindset as an independent variable, self-directed learning ability as a me-diating variable, and learning outcomes as a dependent variable. The collected data were analyzed using SPSS & AMOS 29.0 program for reliability verification, correlation, multiple regression analysis, confirmatory factor analy-sis, and covariance structure analysis.
Results The potential variables of growth mindset, self-directed learning ability, and learning outcome perceived by adult learners showed a significant positive relationship, and the structural relationship between growth mind-set, self-directed learning ability, and learning outcome was also significant. In addition, it was confirmed that self-directed learning ability has a significant effect as a partial mediator in the relationship between growth mind-set and learning outcomes.
Conclusions Growth mindset and self-directed learning ability are core competencies that adult learners should cultivate. Therefore, in order for adult learners who have accumulated life experiences for a long period of time and whose learning tendencies are fixed to adapt to the changing times and live a successful second life, it is neces-sary to find ways to strengthen growth mindset and self-directed learning ability.
Analysis and Direction of the ‘classical poetry’ of the Korean language secondary school teacher appointment test(2002-2024)
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Cho Seong Yoon
Published: October 2024

Objectives The purpose of this study was to analyze the questions in the ‘classical poetry’ area in the Korean Language Department Secondary Teacher Appointment Test (2002-2024), and to suggest what direction to proceed in the future.
Methods Questions in the classical poetry area were extracted from the Korean language department secondary teacher appointment test questionnaire and analyzed ‘tendency’ and ‘type of question’ based on the direction and principles of questions provided by the Korea Institute for Curriculum and Evaluation.
Results The tendency of the questions could be divided into three main categories. First, there was a great tendency to consist of 2-3 passages only within the classical poem. Second, there was a bias in the classical poem section that is presented every year. Third, there were many cases where the works that were presented reappeared in different forms with similar content. The types of questions were analyzed by dividing them by period. First, in the 2000s, there was a great tendency to write questions by memorizing knowledge or content about the work. Second, questions before and after 2010 were presented focusing on knowledge of literary history and understanding and analysis of works. Third, the written questions from 2014 to the present are presented to allow objective evaluation as much as possible, and the narrative questions are presented in the direction of analysis, reasoning, synthesis, and evaluation based on data.
Conclusions Based on the analysis results, four directions for the future classical poetry appointment test are proposed. First, it is necessary to expand the scope of complex passages in classical poetry. Second, reduce the deviation of the frequently asked branches, and evenly present the branches of oral literature, Korean literature, and Chinese literature. Third, develop questions to measure more diverse and higher-order thinking. Fourth, the questions are presented so that the essence of the classic poem, “a poem” and “a song (歌)” can be confirmed or realized.
UKRAINIAN HISTORICAL THOUGHT AT THE PRESENT STAGE (ABOUT A. PALIA'S BOOK «A SHORT COURSE IN THE HISTORY OF UKRAINE»)
Authors:   Academician I.G. Petrovskii Bryansk State University (Russia), Dubrovskii A.M.
Published: October 2024

The article discusses the content of A. Palia's book "A Short course in the History of Ukraine". Paliy is the author of a number of books about Ukraine. His "Short Course" is addressed to a wide range of readers. In 2018, the third edition of this work was published. A. Palia's book consists of 80 essays. There are no new facts, new ideas in the book. In the essays, certain topics are covered in great detail, others are wrongfully given much less attention by the author. Covering the history of Ukraine, A. Paliy does not use falsification. He prefers the method of silence, in which the reader learns a partial truth that is convenient for the author. Incomplete but reliable information looks convincing to the reader, but he cannot find out the true story. An important feature of A. Palia as a researcher is the desire to put forward the great ancestors of the Ukrainian people, simplistically linking the origin and achievements of this people with various other ancient peoples. The book often compares Ukraine with Russia, and Russia is always represented as a backward country, its people are less talented than Ukrainians. Humiliating Russia, the author glorifies Ukraine. Russia is shown in the book as a country that is constantly hostile to Ukraine.
THE MOTIVES OF THE OFFICIALS IN THE CONQUESTS OF THE SMALLHOLDERS LAND IN THE XVIII-TH CENTURY, AS AN INDICATOR OF CAPITALISM
Authors:   The Kursk branch of the ROIA (Russia), Kudlanov K.B.
Published: October 2024

Bureaucratic involvement in capitalist relations is a topic that is relevant to the present day. The researcher is trying to identify this on the basis of the intention of the government officials in the redistribution of the land fund to one-courtyard people. The purpose of the article is to identify the level of penetration of the «spirit of capitalism» into the thinking of the officials on the basis of the motives with which they seized the smallholder's land of the Central Chernozem region in the XVIII-th century. The objectives are: a comprehensive study of bureaucratic seizures of one-courtyard people's land for settlement and sale; determining the level of involvement of those in power in capitalist relations based on a comparison of two types of motives. In the process of the work, analytical-synthetic and comparative-historical methods, as well as retrospective and historiographical analyses. In the study, the author alternately describes two groups of motives for the seizure of one-courtyard people's land. The first corresponded to the feudal era, and the second to the capitalist era. Each of them was subdivided into adjacent and root subgroups. The latter, in both cases, was the most structured and was divided into three types. Among the supporters of subsistence farming, the division took place according to the principle “who settled what was captured”, and among the capitalists, according to the duration of contact of the official with the selected land. The whole structure is based on historical examples. In the course of working on the article, the researcher concludes that in the minds of the bureaucracy in the second half of XVIII-th century, there was a clash of opinions from different socio-economic formations, with a distinct presence of essential signs of the capitalist way of life. At that time, capitalism did not yet occupy in public opinion an absolutely dominant position. However, it was its wide distribution in the future that led to visible tectonic shifts in the middle of the XIX century. Consequently, the full-fledged establishment of one way or another is preceded by the gradual growth of the social narrative of the era, to which the majority of the active population subsequently inclines.
THE JESUITS AND THE FUR TRADE IN THE 17th CENTURY NEW FRANCE
Authors:   Academician I.G. Petrovskii Bryansk State University (Russia), Fedin A.V.
Published: October 2024

The issue of material support for the missionary activities of the Society of Jesus in New France remained one of the most painful throughout its history of the XVII-XVIII centuries. According to many researchers, it was the financial and economic activities of the order in the missionary territories that served as one of the main reasons (and reasons) for its prohibition in the second half of the XVIII century. During the previous century, especially the first half of it, most of the difficulties and problems faced by Jesuit missionaries in Canada were caused by insufficient, or even completely absent, material base of their activities. The participation of Jesuit missionaries in North America in the fur trade has been the subject of intense debate since their appearance in New France and up to the present day. It seems that the representatives of the order were indeed involved in the fur trade, which was caused by the need for material support for their main, missionary, activities. Throughout the period under review, furs continued to be, first of all, the main monetary equivalent in the colony, along with gifts of various kinds, and in this form were used by Jesuit missionaries, as well as by other persons and organizations on its territory and even more so beyond its borders, in the native environment.

The structural and phase composition of TiZr50, AlZr50, TiAl49Zr2 composite materials obtained by the hydride technology was investigated. A model three-component phase diagram was constructed for Ti–Al–Zr at a temperature of 1150°C. The structural state of TiAl49Zr2 alloys was predicted based on reference lattices (USPEX code with VASP interface), quantum-chemical calculations of the energy of TiAl49Zr2 were carried out in the CASTEP code. Solid solutions dominate in TiAl49Zr2, in the composition of which the main elements are predominant: Al10–Ti9Al23–Ti8. Zr atoms can be introduced into the interstitial sites [– 0.257 0.042 0.2545] (St–Zr–27), [0.0053–0.0120–0.0765] (St–Zr–143), [–0.3251–0.3983 0.4880] (St–Zr– 75). The introduction of Zr into the specified lattice sites does not violate the stabilizing effect in the TiAl49Zr2 systems. All reference lattices are stable. In the TiAl49Zr2 alloy, the main phases are Al10Ti9Zr, Al23Ti8Zr, the contributions of which to the theoretical intensity are 78.57 and 21.43%. In the AlZr50 sample, the phases ZrAl, Zr2Al3, ZrAl2.
Comparison of composition, properties and modifying effect in epoxy compositions of natural and synthetic diopside-containing fillers
Authors: Gabdulkhaev K. R. , Valeeva A. R. , Tverdov I. D. , Gottlieb E. M.
Published: October 2024

Diopside is one of the key components in various construction materials and can also be used as a filler for epoxy compositions. However, due to the complexity and labor intensity of developing domestic deposits of this calcium magnesium silicate, it is rational to synthesize diopside based on rice husk ash and dolomite and compare its phase composition and properties with diopside concentrate mined in nature.

It has been established that the synthesized calcium-magnesium silicate, compared to the natural mineral, contains 10 times more diopside, has a 3 times smaller pore volume and an almost 5 times smaller average particle size, i.e. they differ significantly in both phase and granulometric composition, as well as in porosity.

At the same time, both natural and synthetic diopside-containing fillers increase the hardness, wear resistance and viability of epoxy compositions. A filler synthesized on the basis of rice husk ash is more effective in terms of increasing the performance characteristics of epoxy materials.
Effect of lanthanum, ce- rium, praseodymium on corrosion-electrochemical behavior of aluminum conductor alloy AlTi0.1 in NaCl electrolyte
Authors: Ganiev I. N. , Amirov A. Dzh. , Dzhailoev Dzh. Kh. , Zokirov F. Sh. , Amonzoda I. T.
Published: October 2024

The article presents the results of studying the effect of lanthanum, cerium and praseodymium additives (0–1.0 wt.%) as structure modifiers on the anodic behavior of the aluminum conductive alloy AlTi0.1 in the NaCl electrolyte medium. The studies were carried out using the potentiostatic method with a potential scan rate of 2 mV/s. It was found that over time, the free corrosion potential of the alloys shifts to the positive side and acquires a positive value with an increase in the modifier concentration (lanthanum, cerium, praseodymium) in the aluminum conductive alloy. The addition of lanthanum to the aluminum conductive alloy AlTi0.1 by 12–23%, cerium by 20–30% and praseodymium by 25–35% increases its corrosion resistance. An increase in the corrosion rate of the alloys with an increase in the NaCl concentration in the solution, regardless of their composition, was noted. An increase in the concentration of chloride ion in the NaCl electrolyte leads to a decrease in the potentials of free corrosion, repassivation and pitting of alloys.

The paper considers one of the insufficiently explored methods for the synthesis of compounds of the homologous series TinO2n–1, in particular the method of hydrogen reduction. A series of samples (n = 2–8) were obtained from initial TiO2 powders of various chemical purities (99.0–99.99%) with modification with rutile in a wide range of temperatures and reduction times in a hydrogen environment. The influence of the purity of the initial samples, temperature and recovery time on the structure of the resulting compounds was established. Differences in the crystal structure of compounds of the homologous series TinO2n–1, as well as β- and λ-polymorphic modifications of Ti3O5, are shown. An approach to selecting the temperature and time of reduction of TiO2 powders to obtain a specific phase in compounds of the homologous series TinO2n–1 is substantiated.

AlMgB14 ceramics is known as a material characterized by increased hardness in combination with a low friction coefficient. Composite structures based on this ceramics have even higher strength characteristics. In the present work, we investigate the structural-phase states and physicomechanical properties of composite ceramics of the AlMgB14–TiB2 system with a variable TiB2 content, obtained by hot pressing the initial batch based on AlMgB14 and TiB2 ceramic powders preliminarily synthesized by the method of self-propagating high-temperature synthesis. It was found that the resulting materials are characterized by a composite structure represented by TiB2 inclusions distributed in the AlMgB14 matrix. The phase composition of the resulting composites is similar to the phase composition of the initial batch, with 5 to 9 wt. % of the MgAl2O4 spinel phase being formed. The microhardness of AlMgB14–TiB2 composites is up to 19.9 GPa (the hardness of AlMgB14 ceramics obtained by a similar method without additives is 7 GPa). The three-point bending strength of AlMgB14–TiB2 composite materials is 309 MPa.

The paper studies coatings of the Ni–W system alloyed with molybdenum and cobalt obtained by electrodeposition. The effect of the concentration of salts of the alloying element in the electrolyte on the chemical composition of the coatings was studied under various synthesis conditions. All the obtained coatings are nanocrystalline or amorphous solid solutions of tungsten, molybdenum or cobalt in nickel with a FCC crystal lattice. Polarization measurements made it possible to establish that the most resistant to corrosion in a 3.5% NaCl solution is a coating containing 35% W and 8% Mo.

Electroencephalography (EEG) is a valuable tool for studying brain function and identifying neurological disorders. This study aimed to analyze EEG data using various techniques for feature extraction and classification. The data was preprocessed by applying filters and dividing it into epochs. Feature extraction techniques, including Fast Fourier Transform (FFT) in the frequency domain and Continuous Wavelet Transform (CWT) in the time-frequency domain, were applied to convert the EEG signals into scalograms and spectrograms. The primary objective was to classify individuals with Mild Cognitive Impairment (MCI) and Healthy Controls (HC) using the scalograms and spectrograms with 2D Convolutional Neural Networks (CNN) and 2D Convolutional Recurrent Neural Networks (CRNN). The classification results obtained from epochs of different durations (5 seconds and 2 seconds) were compared. The analysis revealed that the 2D CRNN model incorporating scalograms achieved the highest classification accuracy of 87.79% for 5 sec epochs and 88.25% for 2 sec epochs. This demonstrates the effectiveness of using scalograms and spectrograms in combination with deep learning models for accurately classifying individuals with MCI and HC with EEG data.

Injury of the sagittal band, a crucial component of the extensor hood, can occur in various situations, including spontaneous events, trauma, and rheumatic diseases. This case presents a rupture of the sagittal band resulting from chronic irritation caused by a metacarpal head osteoma. A 22-year-old female presented with ulnar subluxation of the extensor tendon at the left third metacarpophalangeal joint, without any history of trauma or pain. Ultrasonography and computed tomography revealed a 1.7 mm-sized bony lesion on the radial side of the metacarpal head, accompanied by a partial tear of the radial sagittal band. Our hypothesis that chronic irritation of the sagittal band by the adjacent bony lesion led to the partial tear was confirmed by intraoperative findings. The lesion was excised, and the radial sagittal band was reconstructed. Histopathological examination confirmed a diagnosis of osteoma. To our knowledge, this is the first reported case of sagittal band rupture caused by an osteoma of the metacarpal head. This case underscores the importance of considering an underlying metacarpal head osteoma in patients with non-rheumatoid joints presenting, in the absence of a traumatic history, with a sagittal band rupture due to chronic irritation.
