The Titles of Monarchs in Medieval Japan
Authors:   The Korean Association For Japanese History, Kim Hyunkyung
Published: January 2025

In previous studies, it has been widely accepted that after the title tennō 天皇 first appeared for the Japanese monarch, it was no longer commonly used in the middle Heian period. However, this view is inaccurate because the distinction between titles for deceased or retired monarchs and those for reigning monarchs was not clearly made in those discussions. This paper analyzes the titles used by the nobility for the monarch after the middle Heian period, based on historical sources, and examines the differences in authority and roles associated with those titles.
Titles such as tenshi 天子, tennō, and kōtei 皇帝, which had been prescribed in the ritsuryō 律令 codes, were already being used interchangeably by the 8th and 9th centuries. By examining the diaries of the nobility from the 10th to the 15th centuries, it is found that, in the 10th century, reigning monarchs were often referred to with terms like jō 上, kinjō 今上, and shujō 主上. In many diaries, shujō appears far more frequently than tennō. However, tennō also appears with considerable frequency in other diaries, so it would be incorrect to claim that the title tennō was never used, or was rarely used, during the medieval period.
Examining several examples, it seems likely that the title tennō was used for the Japanese monarch in the sense of a formal, institutional figure overseeing state affairs and ceremonies, a role that has existed since ancient times. Expressions such as kōke or kuge 公家, kokuō 國王, and kokushu 国主 also emerged in the late ancient period and early medieval period, reflecting the monarch's role as a ruler. However, after the establishment of the Kamakura shogunate, the term kōke evolved to represent the aristocratic or non-military nobility, in contrast to the buke 武家 or jike 寺家. Terms like kokuō and kokushu began to be used more specifically to refer to the Emperor Emeritus or the de facto rulers, such as the Hōjō clan 北条氏, who held power in the shogunate. As a result, the title tennō continued to be used to refer to the monarch's abstract, fundamental role and position as the sovereign ruler.
El nuevo régimen de habilidades del empleado público. Desde los deberes éticos a los factores críticos para la eficacia
Authors: Cabrera-Domínguez José María
Published: January 2025

Objetivos: el objetivo de este trabajo es verificar que las sucesivas tentativas de reforma administrativa no alteran los deberes tradicionales, lo que no es incorrecto, pero parece insuficiente para alcanzar la eficacia que demanda el entorno actual. Para obtener esa eficacia, hay que orientarse a algunas llamadas habilidades blandas: el liderazgo, la comunicación, la negociación y la innovación. Ese resultado de eficacia debe girar sobre las competencias de la persona, poniendo el acento en los tres subsistemas más importantes: la selección, la  formación y la dirección pública profesional, es decir, el liderazgo interno. Metodología: para llegar a esa conclusión, el enfoque de este trabajo es la recopilación de opiniones doctrinales que indican las carencias del modelo actual y que orientan el objetivo central de la renovación hacia las competencias de la persona que ocupa el empleo público, en especial, las indicadas previamente. Resultados: el trabajo limita su opinión, en forma de resultados, a la definición de criticidad de tres elementos en el resultado final: la selección, la formación y el liderazgo interno (a través de la dirección pública profesional). Conclusiones: las conclusiones reclaman agregar nuevas habilidades para el empleo público del siglo XXI, sin perder su componente tradicional (sistema de valores públicos). En un contexto de gobernanza, determinados subsistemas del empleo público (selección, formación y dirección pública profesional) deben ser los protagonistas esenciales de las reformas del empleo público.

Suggestions for the Musical Use of Edutech for Korean Traditional Music Education
Authors:   Gyeongin National University of Education, Lee Jeong-Min
Published: January 2025

This study proposes ways to use Edutech for the purpose of traditional Korean music education. First, the teaching and learning methods presented in the music and education curriculum were structured to select Edutech that reflects the characteristics of Korean traditional music education. Moreover, the large number of digital tools used in music education were categorized into three types: “interaction and collaboration,” “Western music activities,” and “traditional Korean music activities.” Among them, we examined the characteristics of traditional Korean music education media in detail and used Edutech in traditional Korean music classes. In particular, in the areas of singing and creation, we sought strategies for using Edutech to enhance students’ musical abilities through experiences that reflect traditional Korean music elements (e.g., “gayageum app byeongchang,” “tori garak performance and creation,” and “jangdanggol creation”) using digital tools. We hope that through this article, Edutech that focuses on the essential goals of traditional Korean music education will be activated and help carry out meaningful traditional Korean music activities.

Authors:   Gyeongin National University of Education, Yun Sung-Jun , Ahn Ji-Hoon
Published: January 2025

This study aimed to confirm the influence of pre service teachers’ physical self-concept on physical education teaching efficacy and to verify the moderating effect of teacher efficacy for teacher–student relationships perceived by preservice teachers in this relationship. To this end, a survey was conducted on 121 preservice teachers at universities of education located in the metropolitan area. Descriptive statistical and correlation analyses were conducted in consid eration of the study’s purpose, and the moderating effect was verified through hierarchical regression analysis. The following results were obtained: First, preservice teachers’ physical self-concept and teacher efficacy for teacher–student relationships showed a positive correlation with physical education teaching efficacy. Second, the teacher efficacy for teacher–student rela tionships of pre service teachers exerted an independent influence on the physical education teaching efficacy even when the description of physical self-concept was controlled. Third, the teacher efficacy for teacher–student relationships of preservice teachers statically moderated the relationship between physical self-concept and physical education teaching efficacy. This study found that physical self-concept and teacher efficacy for teacher–student relationships are meaningful psychological variables to enhance physical education teaching efficacy.

Предлагается метод тепловой диагностики трения, позволяющий определять момент трения в самосмазывающихся подшипниках скольжения по температурным данным с учетом вращающего движения вала. Температурный режим в узле трения описывается в неподвижной цилиндрической системе координат двумя уравнениями теплопроводности. Уравнение для вала содержит конвективный член, учитывающий вращение вала с известной скоростью. Приводится методика определения временного шага при численном решении уравнений, обеспечивающего сходимость приближенного решения с точностью, пригодной для практического использования. Сопоставлением расчетных и экспериментальных температур показана адекватность модели реальному тепловому процессу в подшипнике скольжения. Момент трения в подшипнике скольжения определялся по температурным данным путем решения обратной задачи теплопроводности. Сравнением расчетных и экспериментальных значений момента трения установлена эффективность тепловой диагностики трения.

A method of thermal diagnostics of friction is proposed, which makes it possible to determine the friction torque in self-lubricating sliding bearings using temperature data, taking into account the rotating motion of the shaft. The temperature regime in the friction unit is described in a fixed cylindrical coordinate system by two heat conduction equations. The equation for the shaft contains a convective term that takes into account the rotation of the shaft at a known speed. A technique is presented for determining the time step in the numerical solution of equations, ensuring the convergence of the approximate solution with accuracy suitable for practical use. A comparison of calculated and experimental temperatures shows the adequacy of the model to the real thermal process in a sliding bearing. The friction torque in the sliding bearing was determined from temperature data by solving the inverse problem of thermal conductivity. By comparing the calculated and experimental values of the friction moment, the effectiveness of thermal diagnostics of friction was established.

Цель: Исследование и выявление специфических особенностей особых экономических зон регионов России и стран мира в части их направленности на научно-технологическое развитие. Задачами исследования являются выявление особенностей развития различных видов особых экономических зон в России и зарубежных стран; выявление особенностей развития особых экономических зон в регионах России. Проведение исследования базировалось на использовании методов сравнительного анализа законодательства и экономической политики применения ОЭЗ различных стран мира и регионов России, а так же их государственной научно-технологической политики, что позволило выявить проблемы и методы их решения в развитии ОЭЗ в части реализации государственной научно-технологической политики. В регионах России необходима корректировка экономической политики в реализации проектов особых экономических зон в части добавления процессов абсорбции объектов интеллектуальной собственности академическим сектором регионов с целью создания собственных результатов интеллектуальной собственности через интенсификацию научно-технологической политики по модели догоняющего развития. Происходящие изменения внешней среды России вызвали необходимость технологической независимости в ее экономике. Особые экономические зоны, прежде игравшие роль привлечения инвестиций в регионы в новых условиях, должны стать основой технологического развития регионов. Переход от глобализации к деглобализации актуализирует в особых экономических зонах реализацию активной научно-технологической политики государства по модели догоняющего развития. Данный переход актуализируется в целом ряде уже действующих документов: в Указе Президента Российской Федерации от 28.02.2024 г. №145 "О Стратегии научно-технологического развития Российской Федерации", в Постановлении Правительства РФ от 17.06.2022 №1101 (ред. от 29.09.2023) предоставляющей субсидии федерального бюджета для автономной некоммерческой организации "Платформа Национальной технологической инициативы" для создания "Предпринимательских точек кипения" в вузах по "Платформе университетского технологического предпринимательства" согласно государственной программы РФ "Научно-технологическое развитие РФ".
Analysis of successful practices and determination of promising directions for implementing innovations in the sphere of housing and communal services in Russia
Authors: Mutolapov R. Kh.
Published: January 2025

Since the key direction of modern development is the introduction of digital technologies in order to optimise all the aspects of economic activity, the main focus of the work is aimed at analysing the current state and prospects for the introduction of innovations in the housing and utilities sector (here-inafter referred to as HUS) from the point of view of digitalisation of the industry.

   To achieve this goal, we have used the analysis of statistical data in the context of the economic activities to determine the current level of innovative development of the HUS of Russia as well as individual indicators of the distribution and effectiveness of applying digital solutions in the industry. In the course of the work, it has been found that it significantly lags behind the average Russian indicators of innovation of innovative activity of companies, expenses on innovations as well as of modern products, works, and services. In the formation of the Russian “industry 4.0”, the HUS also demonstrates a significant lag in the development. The use of the most advanced and promising digital technologies is at an extremely low level, and the digital solutions applied in the activities of companies in the industry demonstrate extremely low efficiency rates, and most of them have virtually no significant impact on the work of the organisations. We believe that the negative experience of investing in the digital infrastructure is the reason for low involvement of the HUS companies in the fourth industrial revolution and low indicators of the innovative development on a national scale.

Authors: Groshev I. V. , Menin He
Published: January 2025

The article considers the processes of organisational culture management in the conditions of digitalisation. It is indicated that its digital transformation in the modern global market is one of the conditions for the survival of companies, the main components of which are presented by the authors in the form of a model. The advantages of the digital organisational culture and difficulties of the process of its digital transformation are considered separately. The key elements of the digital organisational culture and the arisen processes of change and transformation are analysed in detail. The latter affect the strategy, structure, and management processes of the organisation, and are aimed at optimising the management system, ensuring a balance between personnel and technology. At the same time, the authors emphasise that it is extremely difficult to formulate a general systemic picture of the digital organisational culture. As a conclusion, it is noted that at the present stage of the development of the Russian economy, the digital organisational culture provides certain advantages by influencing the formation of the organisational structure, creates a positive and constructive working environment, forces companies to set new goals and change their activities. As a result, the digital transformation of the organisational culture of companies can help reduce operating costs, promote the creation of new products and services or improvement of the existing ones, and improve the quality of interaction with customers and employees.
Formation Accelerated Stress Test (FAST): A New Technique to Study Anode Passivation in Lithium-ion Cells using Differential Capacity, Low Salt Concentration and Low Temperature.
Authors: Gauthier Roby , Lin Hongyi , Chen Haotian , Viswanathan Venkatsubramanian , Whitacre Jay
Published: January 2025

This study investigates the formation and properties of the solid electrolyte interface (SEI) in lithium-ion batteries under varying salt concentrations (0.4M, 0.8M, 1.2M) and low formation temperatures. This method was used as a formation accelerated stress test (FAST) to evaluate the impact of different solvent blends and additives on anode passivation using the reduction rate of ethyl methyl carbonate (EMC) seen in the differential capacity of cells containing them as a performance metric. Electrolytes containing a mixture of vinylene carbonate and ethylene sulfate showed superior passivation, while a 3:7 mixture of fluoroethylene carbonate and ethyl methyl carbonate proved to be the most effective at passivating. Furthermore, the low-viscosity solvents methyl acetate and acetonitrile significantly enhanced SEI passivation during formation at the anode due to lower graphite exfoliation. We also show that the differential capacity data correlate with long-term cycling performance for some of the chemistry studied here. These results provide valuable insights for the efficient design of a new formation accelerated stress test (FAST) that could accelerate the discovery of high-performance electrolytes through rapid monitoring of SEI passivation during formation.
Identifying driving and spectator phonon modes in pentacene exciton transport
Authors: Lynch Pauline , Frontiera Renee
Published: January 2025

In organic semiconductors, crystal packing motif is known to modify electronic properties, like exciton transport dynamics. Phonon vibrations can drive or hinder exciton transport and understanding the role of these intermolecular vibrations can aid in the rational design of materials for improved solar cell efficiency. In this paper, we use a double pulse spatially offset femtosecond stimulated Raman spectroscopy (SOFSRS) to identify the functional role of phonon modes in pentacene exciton transport. In SOFSRS, we photoexcite our sample at a spatially offset position relative to the Raman pump and probe, which allows us to track changes in the excited state structure over micron length scales and femtosecond timescales during exciton transport. We first measure the phonon modes in a single crystal and then use optical pulse shaping to selectively amplify each mode and measure the resulting exciton transport dynamics along the fast and slow transport axes using SOFSRS. We compare the resulting dynamics with a single pulse excitation SOFSRS to unambiguously assign driving and spectator phonon modes. We find that a 91 cm-1 phonon mode drives exciton transport preferentially along the slow transport axis. We also find two modes at 161 and 176 cm-1 that drive an increase in the overall excited state population and use computations to assign a plausible mechanism. This study presents a new experimental method that is capable of determining the functional role of phonon vibrations in mediating exciton transport.

The intensifying plastic production and poor management of its waste have led to a tremendous rise in the dumping into aquatic ecosystems, thus resulting in harmful effects on living organisms as well as biodiversity loss and wetland threat. The study aims to assess the availability of microplastics in a freshwater environment (the Joumine stream, Northern Tunisia) by determining their abundance, shape, type, color, and size in both water and sediment. Thirty samples were collected from five sites and analyzed for MPs using stereomicroscopy and FTIR spectroscopy. The average value of microplastics was found to be 8.87±3.94/L (in water) and 18.2±8.27/50g dry weight (in sediment). The most dominant form in all samples was fibers, while the color category varied according to the two considered matrices and sites. Microplastic particles in the samples ranged from 0.24 to 1.45 mm in length. Polypropylene and polyethylene were the identified types of polymers. Overall, the level of microplastic pollution along the Joumine stream was found to be relatively average compared to the global pollution level. It underlined the fact that MPs are widespread even in freshwater environments and provides a baseline for future surveys and management sustainable decisions.

Authors: Santoso Indriyani , Kurniawan Rizal , Sartana  , Suryani Cahya
Published: January 2025

Individuals frequently seek information and then share that information. The research looks into the dynamics of these two behaviors on the social networking site Facebook. The study included 260 students, the average age of whom was 20. The Information Seeking in Facebook Scale (ISFS) categorizes information seeking behavior on Facebook into five types: social searches, social browsing, hedonic productivity, consumer trends, and general erudition. Meanwhile, students' information-sharing behavior was examined based on the frequency with which they shared information links via the Facebook network in the previous three months. The data obtained was analyzed using logistic regression. As a result, it was discovered that social search and social browsing are important types of information searches to determine the likelihood of someone sharing information. The findings of this study contribute to the flow of searching and sharing information, which can change thought patterns and attitudes and create behavior in the general public, particularly students.

The smoking behavior scale, the academic stress scale, and the smoking self-efficacy scale were the tools used in this investigation. Multiple regression analysis was used to examine the data. Multiple linear regression analysis results indicated that smoking self-efficacy and academic stress have a significant predictive relationship with smoking behavior. This variable has a coefficient of determination of 28.8%. Stress from school has a lower contribution than smoking self-efficacy. Therefore, increasing smoking self-efficacy through improved emotional regulation skills and assertiveness when declining offers to smoke can help reduce adolescent smoking behavior. In addition, teaching teenagers how to adaptively handle their academic stress will prevent them from turning to smoking or cigarettes as a coping mechanism.

Introduction. Currently, in road construction, in order to reduce energy costs and harmful emissions, warm asphalt concrete mixture technologies are being increasingly used. One way to reduce the temperature of asphalt concrete mixture prepared is to use additives based on natural and synthetic waxes. In this regard, it is important to study the influence of wax additives on the properties of bitumen binder as a basic component of asphalt concrete mixture. The adhesion between the binder and the mineral filler is the most important property that determines the durability of an asphalt concrete pavement. The purpose of this article is to study the effect of synthetic wax additives on the adhesive properties of bitumen.

Materials and methods. The characteristics of the studied synthetic wax additives Viskodor PV-2, Sasobit and Licomont BS-100 have been presented. To simulate binder aging, the heating method in a thin layer, according to GOST 18180, was used with the temperature control time increased to 9 hours. To assess the adhesion between original and modified bitumen binder, as well as the aged binder, the method of boiling stone material coated with bitumen was used, and the assessment of its appearance in accordance with GOST 11508 was made. The study of the adhesion mechanism for the bitumen binder and the mineral filler was carried out by means of spectral analysis.

Results and discussion. The influence of synthetic wax additives on the adhesion between bitumen binder and mineral material was analyzed. A change in the adhesive properties of bitumen modified with the studied additives during thermal-oxidative aging was revealed. A comparison was made of the IR spectra of the original and modified bitumen before and after interaction with stone material and the differences in the mechanisms of affecting the adhesion to the mineral filler by the introduced additives were determined. It has been established that the Viskodor PV-2 additive significantly improves bitumen adhesion. Moreover, the effect of improved bitumen adhesion with this additive remains after thermal-oxidative aging, though slightly reduced. Imported additives Sasobit and Licomont BS-100 have a significantly less impact on the adhesive properties of bitumen.

Сonclusion. The results obtained show that the use of synthetic wax additives improves the adhesive properties of bitumen, which can positively affect the durability of the road surface. Since the domestic additive Viskodor PV-2 is superior in the effect of improving the adhesive properties of bitumen compared to the studied additives Sasobit and Licomont BS-100, the introduction of this additive into production instead of expensive imported additives will provide both improvement in the quality of asphalt concrete pavement and reduction of costs.

Salmonellosis is a common digestive infection of the food chain, so it is important to provide bio-logical protection of poultry farms to exclude economic losses and prevent horizontal transfer of Salmo-nella bacteria through chicken products (eggs, meat) to humans. The aim of the study was to conduct comprehensive monitoring and study the resistance of industrial chicken farming in some poultry farms in Almaty region of Kazakhstan to bacteria of the genus Salmonella. The research methodology was based on weekly sampling from the environment of poultry farms in Almaty region of Kazakhstan and determination of the presence of bacteria of Salmonella genus in the selected samples by culture and biochemical methods. Samples from the technological facilities of poultry farms were taken from the entire calendar year. A total of 5672 samples were collected for testing, including 537 samples of litter, 3838 samples of flushes, 1024 samples of eggs, 181 samples of dust, 43 samples of straw, 49 samples of transport crates, litter paper and cardboard used for transport crates. Of the 5672 samples tested, the presence of Salmonella bacteria was recorded in 24 samples (0.5% of all samples tested). The results of these studies showed that detection of Salmonella bacteria in the tested samples is an effective method of biosecurity management for poultry farmers and allows them to quickly find sanitary and zoohygienic solutions in order to prevent the threat of Salmonella bacteria in chicken farms. Therefore, the efforts of poultry farms to reduce the transmission of Salmonella bacteria through chicken products should be realized on the scale of Kazakhstan.

The article was written as part of the Ministry of Science and Higher Education of the Republic of Kazakhstan’s project AP 23486220, titled “Study of the important organ systems reactivity in the main commercial fish species of the Ile-Balkhash basin under anthropogenic load.” (2024-2026). The article represents the study investigating the long-term effects of polyethylene terephthalate (PET) microplastics on zebrafish (Danio rerio). Zebrafish exposed to PET microplastics at concentrations of 1.9 mg/l and 5.64 mg/l exhibited significant kidney and gill damage. This included necrosis, circulatory disorders, and tissue damage. Histological analysis revealed specific pathological changes such as vacuolization and hyaline-droplet degeneration in kidneys, and destruction of epithelium and lamellae in gills. Notably, no compensatory-adaptive reactions in gills were observed, indicating a lack of adaptation to prolonged exposure. These findings suggest that microplastics may migrate through the bloodstream, disrupting normal kidney and gill structures. The study highlights the severe impact of microplastic pollution on fish organs, emphasizing the urgent need for further research to develop strategies for mitigating microplas-tic pollution in aquatic ecosystems. Additionally, the observed lack of adaptive responses underscores the potential for significant ecological consequences, urging immediate attention to address this critical environmental issue.

Background: Histological processing encompasses the steps of acquiring fresh tissue, preserving it through fixation to maintain its natural appearance, slicing it into thin sections, placing the sections on glass slides, and subsequently staining them. This enables the observation of various histological components within the tissue using a microscope. The objective of this study was to ascertain the microscopic characteristics of heparin preparations and the kidneys of mice (Mus musculus) through fixation using a formalin buffer solution.Method: This kind of research encompasses experimental research. The study employed a purposive sample methodology in its research design. This study concludes that preparations containing images provide a representative depic-tion of the cell nucleus, cytoplasm, and exhibit consistent coloration with different cutting thicknesses. The standard thickness for cutting the mice hepatic tissue using a microtome is 5 μm.Result: This thickness yields good microscopic results overall, with 25 field views from 5 preparations. The percentage of high-quality microscopic images obtained at this thickness is 100%. The statistical analysis revealed significant differences (p<0.05) between the 2 μm and 5 μm groups, as well as between the 5 μm and 8 μm groups. There was no statistically significant difference (p>0.05) observed between the 2 μm and 8 μm groups in terms of many aspects including structural, nucleolus, cytoplasm, color uniformity, and total structure scores.Conclusion: The optimum thickness in this research was 5 μm. Additional investigation is required to examine the microscopic characteristics of tissue samples by varying the duration of staining on the samples.
