Authors: Mou Yajun , Li Peiran , Li Tianyi , Qiu Bin , Jiang Dayong
Published: September 2023

Squeak and Rattle (S&R) of automotive door panels seriously affect consumers' perception of vehicle quality. In order to accurately analyze the S&R problem, BP software was used to build an S&R analysis finite element model of the interior assembly of the door interior, taking into account the pre-compression between the interior door panel and the sheet metal during installation. The excitation transmitted from the body to the door through the hinge is tested, and the modal transient analysis of the model is carried out by BP software. Combined with the S&R noise risk assessment standard, the analysis results were evaluated, and the S&R points were determined. Through the bench test, it is verified that the test risk points are consistent with the analysis results, indicating the accuracy of the S&R simulation analysis. Based on the modal contribution, the S&R risk points are optimized and analyzed. Through optimization analysis, the abnormal noise risk is reduced. The results show that in the digital model design stage, the door panel S&R risk analysis based on BP software can be carried out for abnormal noise risk prediction and optimization analysis, that greatly saves development time and reduces development costs.

Authors: Xuan Li , Jin Zhu , Qi Huang , Xiaojun Zhou
Published: September 2023

The size of the oil pipes in the factory is relatively large, making them inconvenient to handle. There are few existing oil pipe handling devices, and a 2P2R four degree of freedom manipulator device has been innovatively designed to complete the oil pipe handling work. First, the three-dimensional model of the manipulator was established using SolidWorks software, and then the improved D-H method was used to carry out the kinematics modeling of the manipulator system, and the forward and Inverse kinematics equations were derived. Then, the MATLAB software was used to carry out the kinematics analysis of the manipulator, and the manipulator workspace was calculated. The movement trajectory, as well as the displacement, speed, and acceleration curves under the trajectory were obtained using the fifth order Polynomial interpolation method, Finally, the 3D model was imported into Adams software, and an Adams virtual prototype was established for dynamic analysis. The force and torque curves of each joint were obtained, laying the foundation for further design and research in the future.
Automatic modal identification of bridges based on free vibrations and advanced signal decomposition techniques
Authors: Mazzeo Matteo , De Domenico Dario , Quaranta Giuseppe , Santoro Roberta
Published: September 2023

Free vibration tests are attractive because they can be performed by means of a network consisting of few sensors temporarily installed on the structure in such a way to limit duration and cost of the experimental campaign. Additionally, free vibration tests are usually performed by introducing an initial perturbation that can induce a structural response significantly higher than the ambient excitation. This, in turn, allows to reduce the noise-to-signal ratio in the final measurements and/or to consider less stringent requirements about the technical specifications of the sensors. Since free vibration tests can provide accurate estimates of the modal parameters while being rather cheap and easy to implement, they have been performed in many applications, such as the experimental dynamic characterization of base-isolated buildings, masonry towers, ancient tie-rods, and bridges. An efficient and automatic computational framework is thus presented for the modal identification of bridges based on their free vibrations. The novel procedure proposed in the current work combines advanced signal decomposition techniques and a robust approach for damping identification. Two advanced signal decomposition techniques are considered, namely the Variational Mode Decomposition and the Empirical Fourier Decomposition. Experimental applications are then illustrated for roadway and railway bridges.
Development of inertial piezoelectric linear actuator with asymmetric design
Authors: Čeponis Andrius , Jūrėnas Vytautas , Mažeika Dalius , Deltuvienė Dovilė
Published: September 2023

This article represents a numerical and experimental investigation of a piezoelectric linear actuator with asymmetric design. The actuator is based on a square-shaped rod with asymmetrical cut and T-shaped clamping. The cylindrical rail, with slider, is on the opposite side of the T-shaped clamping. The low-volume and mass of piezoelectric actuator allows to mount it directly to printed circuit board (PCB). The actuator operation is based on the inertial stick – slip operation principle inducted by the first longitudinal vibration mode excited by two sawtooth signals with phase difference π. Furthermore, the longitudinal vibration mode induces bending deformations of the rod, increasing the displacements of the cylindrical rail. The results of numerical and experimental investigations have validated the actuator operating principle, as well as shown that the displacement amplitudes of the guidance rail have reached 153.6 μm at the 200 Vp-p excitation signal amplitude, while the linear motion speed reached 45.6 mm/s at the same excitation signal.
Vibration and noise characteristics of an inverter for electric vehicle application
Authors: Singh Rahul , Nalawade Amogh , Pande Manish , Singh Punit
Published: September 2023

Noise, Vibration & Harshness (NVH) is one of the key parameters associated with comfort of an automobile. An Electric Vehicle (EV) consists of transmission driven by electric motor which ultimately gets its power or current supply from inverter. As per Electric vehicle architecture, motor ranks first followed by transmission and inverter in terms of NVH performance. The function of an inverter is to convert DC current from battery source to 3-phase AC current which goes to electric motor. Torque and speed characteristics of motor is dependent on current and voltage supply from inverter. Hence it is important to assess NVH characteristics of inverter as well. In this paper, vibration and acoustic performance of a standalone EV inverter have been studied by testing it at different vehicle operating conditions. Ideally the output 3 phase AC current from inverter should contain only electrical frequency, but it is observed that AC current contains harmonics in the form of linear combination of electrical frequency and switching frequency. From this study, observations from NVH tests on an EV inverter is highlighted in frequency range where relatively high vibration and noise levels were present.

Authors: Fuyu Guo , Jianguo She , Ning Chen
Published: September 2023

This paper mainly studies the mechanism and efficiency of ammonia-nitrogen removal from circulating sewage in closed fish tank system. According to some factors affecting the removal efficiency (ultrasonic power, ultrasonic time and water oxygen concentration). Simulated circulating sewage mixed with oxygen through a venturi tube and then entered a closed experiment box for ultrasonic experiments. Finally, the removal efficiency was determined by Knott's reagent photometry. In the experiment, the PH value of the simulated sewage was 7.5, the indoor water temperature was 20 °C, and the free ammonia was selected as 0.02 mg/L (total ammonia-nitrogen was 1.6 mg/L) according to the standard. The experiment found that when the ultrasonic power is 400 W, the action time is 2 h, and the oxygen concentration of water is 23.8 mg/L, the efficiency of removing ammonia-nitrogen in water is about 65 %. When applied on fishing vessels, increasing the power can increase the removal efficiency.

Published: September 2023

Walking is one of the most crucial activities of humans. It is very important for their everyday life, working, shopping, going to jobs, for their well-being and also for communications with friends, relatives, social contacts, and similar. Of course, when the body changes the way people are walking changes too. This is something everybody anticipates to be true and believes to be true. The question is can we quantify this and how much actually changes with age in the way we do walking? This is the main issue we try to elucidate in our article. To do that we consider two groups aged 18-25 and aged 30-40 and analyse what are the basic changes during walking. We do that by creating a biomechanical model of the human body and its computer implementations within a CAD system. The model enables computer simulation and computer design for anthropomorphic robotic applications as well as for medical applications (orthopaedics, traumatology, orthotics, and prosthetics design), among other things.

Published: September 2023

Auditor switching has become an exciting topic when the auditing environment dynamics continues to develop. This study is intended to examine the relationship between auditor switching and their influential factors by considering the company's financial problems. Using logistic regression statistical methods to examine the data, this study shows that audit fees, KAP reputation, and company growth affect auditor switching, while audit opinion has no effect. Furthermore, financial distress can only influence the relationship between company growth and auditor switching. This study provides in-depth insight into the relationship between client firm characteristics and auditor changes mediated by financial distress. This study would expand on similar studies conducted in Indonesia. Given that the audit environment is constantly evolving, it is expected that the results of this study will enrich the existing literature.

Initial idea to focus a plenary panel of 19th International Conference “Evolution of International Trading System: Prospects and Challenges” held in St. Petersburg State University on March 17th–19th 2022 on the issue of interaction between political and trade dimensions of international cooperation came to the organizers as early as mid-2021. Substantial escalation of the geopolitical tension by Spring 2022, on the one hand, made the selected topic much more relevant, on the other hand additionally limited the list of potential discussants. Nevertheless, despite of this obstacle programme committee managed to arrange the international team of experts giving their answers to the questions asked by moderators. The questions included necessity and possibility for the radical reassessment of the perception traditionally prevailing among social scientists. According to this perception expansion of trade has the positive impact on political relations between trading partners. Another topical issue deals with possible repercussions of economic sanctions actively imposed by some members of international community. The experts also discussed the motives behind decisions made by many foreign companies to exit from the Russian market. At the final stage of the panel its participants expressed their views on the prospects of the global governance system reforming.
International trade disputes related to fish products and Agreement on Fisheries Subsidies: Key regulatory issues and litigation outlook
Authors:   St. Petersburg State University, Wang Ruoxuan , Popova Liudmila ,   St. Petersburg State University
Published: September 2023

Fish-related trade disputes dealt with by the World Trade Organization (WTO) arise from the complexity of the fisheries industry, and the transboundary nature of fish, combined with differing national policies and interests. The Agreement on Fisheries Subsidies (AFS) aims to strengthen the role of the WTO in regulating the fish trade and curbing unsustainable fishing practices such as illegal fishing, overcapacity, and overfishing by limiting excessive fisheries subsidies. This article reveals the legal framework of the WTO to regulate the fish trade and resolve trade disputes and outlines the prospects for fish trade in light of the Agreement on Fisheries Subsidies (AFS). It has been established that general principles, quantitative restrictions, and anti-dumping measures, rather than subsidies, are the most common legal issues in trade disputes on fish products. Technical trade barriers, sanitary and phytosanitary measures, and general national exemptions are also frequent sources of disputes in the fish trade. These measures, designed for safety, health, and environmental reasons, are increasingly used for protectionist purposes by creating trade barriers. The AFS expands the legal framework for resolving trade disputes in the field of fish trade after its ratification. However, this recent international regulation combined with climate change and tightening food standards, is expected to lead to more disputes with developing countries over the fish trade.
Economic aspects of state support of Russian steel industry enterprises in the conditions of external shocks
Authors:   Russian Presidential Academy of National Economy and Public Administration, Zaytsev Yuri
Published: September 2023

The metallurgical sector of Russia has been a recipient of state support at the federal and regional levels for many years. The sector receives subsidies from more than 90 programs and indirectly benefits from pricing policies for electricity, natural gas and rail transport. However, the analysis of measures to support the sector under the conditions of Western sanctions and the coronavirus pandemic is of particular relevance. The aim of the work is to determine the role of state support for steel producers in the face of external shocks — the coronavirus pandemic and Western sanctions. The working hypothesis of the study is the assertion that direct and indirect measures related to supporting the sector in the face of sanctions and the negative consequences of coronavirus contribute to reducing the adaptation costs of producers, as well as increasing their competitiveness. The stated goal and the indicated hypothesis determine the structure of the paper. Thus, the author examines the theoretical and practical aspects of the impact of sanctions on the national economy, the Russian steel market, state policy towards the steel industry, as well as direct and indirect measures of state assistance that affect the steel production sector. The research methodology is based on a comprehensive review of indirect and direct mechanisms of state support for the industry. The study resulted in the identification of channels of state influence on the steel market in the context of the COVID-19 pandemic and sanctions. The results of the study can be used in the formation of the Russian industrial policy.

Published: September 2023

The diary of the Japanese poet Sogi (1421–1502) “Shirakawa kiko” (“Journey to the Shirakawa Barrier”, 1468) is analyzed. The sacred place, sung in the lyrics of the past, is the beginning of the song (utamakura). The diary is divided into two parts. This is the result of the development of the genre in the art of renga (connected stanzas) poets. The subject of the study is the prose part. It reveals an increased suggestiveness (yojo) of artistic speech. In the reminiscent variety, a picture of intertextual discourse is formed, the significance of the literary tradition is revealed. It makes up the latent layer of the text, covering the entire narrative. The essay is considered as a memoir diary, it is dominated by emotional content (aware), dating back to the cult of feelings of the aristocratic era. In the chronotope of the diary, a plexus of times and spaces is found, creating an illusory vision of reality as a reflection of the poet’s Zen consciousness. The journey remains unfinished, affirming the infinity of the path and recalling the rotation of the wheel of samsara — the cycle of life and death. The path in the illusory, changeable world affirms the idea of mortal existence (mujo), which has become the fundamental Zen Buddhist concept of the diary.
Representation of Zoomorphic Images in Karachay-Balkar Proverbs and Sayings Using Elements of Frequency Analysis
Authors:   Institute for Humanitarian Studies of the Kabardino-Balkarian Scientific Center of the Russian Academy of Sciences, Berberov Burkhan A.
Published: September 2023

The article is devoted to the representation of zoomorphic images in Karachay-Balkar proverbs and sayings using elements of frequency analysis based on “AntConc” concordancer. During the analysis, we found that the images of sixty animals were reflected in the Karachay-Balkar folklore. To form a more complete picture of the world, the article further reveals the images of individual animals, including by conducting a comparative analysis with proverbs and sayings of other peoples. The author pays special attention to rare zoomorphic images, i. e. those animals that are not represented in the territory of modern residence of Karachays and Balkars (for example, elephants, lions and tigers). The analysis conducted allows to conclude that the zoomorphic images used in Karachay-Balkar proverbs and sayings are largely universal and are reflected in various cultures and languages. However, the most popular images are those that together make up the appearance of the Karachay-Balkar shepherd’s work. The identified animals can be classified into the following four categories: animals watched by the shepherd, his assistants, pests, and animals that make up his ration in the mountains. The results obtained can be used in teaching schoolchildren and students the Karachay-Balkar language, as well as become a starting point for conducting and developing similar studies in the context of other languages, including those belonging to the Turkic language group.

Published: September 2023

Reduced growth rates of working memory in pre-school children during periods of social isolation have previously been documented. However, the question of whether and how long it takes children to compensate for these deficits has remained open. The present study examined the longitudinal dynamics of verbal and visual working memory development in children between the age of 5 and 7 inclusive, taking into account home environment factors such as the duration of screen time during the pandemic and the number of children in the family. Screen time during social isolation was reported to range from 2 to 44 hours per week. The general pattern of development of verbal and visual working memory during this period was a natural increase, independent of screen time and number of children in the family. However, as the screen time increased, both the actual level of development of verbal working memory at each diagnostic cut-off and the rate of its development as the child grew older decreased. The most pronounced negative impact on verbal working memory development from extended screen time was reported among only children in the family. Continued use of digital devices led not just to a slower rate of development of verbal working memory, but to a temporary regression of it. Children in this part of the sample were able to compensate for the regression in verbal working memory development and catch up with their peers only after returning to a systematic educational process in resumed kindergartens.
Saints who sailed from the sea: «German» model of foolishness in Old Russia
Authors:   The Program Systems Institute of the Russian Academy of Sciences, Sukina Liudmila Borisovna
Published: September 2023

The article attempts to put forward and substantiate a hypothesis about the use of a special model of this feat in the formation of the cult of some holy fools of the Russian Church, borrowed not from the eastern, but from the western medieval religious culture. Some lives of Russian holy fools noticeably fall out of the Eastern Christian tradition, with which old and modern historiography links their hagiography. Despite the veneration of the Byzantine σαλος in Ancient Russia, in its religious life the practices of foolishness occupied a marginal position for a long time. In the process of formation and development of the «national» cult of holy fools in the Muscovite state, one of the options for explaining where such ascetics came from was their foreign origin. In the article this problem is considered on the material of the hagiography of Isidor of Rostov and Procopius of Ustyug. In their Lives, one can single out a topic that is common to them and unusual for Russian hagiography. Both saints are repeatedly referred to in the texts of their Lives as foreigners who previously lived in Western countries, «German land». Both found in the Orthodox faith their «spiritual fatherland» and abandoned the «Latinism». In the Lives of each of them, «foolishness» is explicated as the main religious practice. But this is not the «obscenity» of the Eastern Christian σαλος, but a desire for solitude and wandering close to the model of behavior of the saints of the Western Middle Ages. In both lives there is a motif of the sea. Based on the observations and arguments presented in the article, it can be assumed that the compilers of the hagiographies, creating the image of a holy fool-foreigner unknown to Old Russian literature before, were guided by hagiographic texts not only of Greek-Byzantine, but also of Western European origin, some of which were available in Slavic translations. The saturation of the texts with Novgorod plot details indicates that Novgorod, which had long-standing and extensive cultural ties both with the post-Byzantine world and with the countries of the Baltic region, could be the place for constructing this new model of holiness for Old Russia.
Russian saints and the struggle against Latinism in the 15th–16th centuries: Byzantium or the Baltic?
Authors:   St. Petersburg Theological Academy, Kostromin Konstantin Alexandrovich
Published: September 2023

The schism between the Western and Eastern churches, which formally took place in Constantinople, gave rise to a rich polemical literary tradition, but anti-Latin theme entered relatively late into hagiography as a special literary genre. This did not happen in Byzantium until the 30s of the 13th century. There is not a single hagiography completely devoted to the denunciation of the Latins in the Greek circle of writing (in Byzantium, Cyprus and Crete, Palestine and Mount Athos) of the 13th–16th centuries. This topic is associated exclusively with biographical details and is mentioned episodically in the hagiographies. None of the monuments of late Greek-Byzantine hagiography with anti-Latin fragments entered the Old Russian literature. On the contrary, there is not only an increase in interest in this topic in ancient Russian literature, but there is even a life written purposefully as an anti-Latin pamphlet — the life of the holy martyr Isidore of Yuryev. The dynamics of the emergence of anti-Latin theme in Old Russian hagiography is asynchronous with Byzantine hagiography — it became relevant in Old Russia only in the second half of the 15th century. Almost all Russian saints whose lives contain anti-Latin themes are associated with the Baltic region. This is the legendary origin of the holy fools Isidor Tverdislov of Rostov and Procopius of Ustyug, the monks Anthony the Roman and Serapion of Pskov, the military-political activity of the prince Alexander Nevsky and the holy martyr Isidor’s of Yuryev death at the hands of the Latins. The article concludes that Byzantine hagiography did not play a role in the formation of anti-Latin theme in ancient Russian hagiography.
In the service of the clergy and the world: St. Benno in the history of Saxony
Authors:   St. Petersburg State University, Prokopiev Andrei Yuryevich
Published: September 2023

Until recently, historiography has lacked major comparative studies on the phenomen of Holy in Central Europe. Meanwhile, there were very vast regions in which there were no local saints until the end of the Middle Ages. One of these historical regions was Upper Saxony. What was the way of formation of the sacral cult here? What political or socio-cultural factors played a decisive role in the emergence of the cult of saints? And what were the functions of the saints in a changing society? The problems are studied on the example of St. Benno, Bishop of Meißen, who was canonized in 1523. He became the last saint of the medieval Latin Church and the first saint for the Wettin dynasty. The article shows the instrumentalization of his memory at various stages. From the 13th century he acted in the service of the bishops of Meißen, who aspired to become imperial princes. From the 15th century the princely dynasty of the Wettins (Albertine House) was busy about the canonization of Benno in order to strengthen their own authority in the Holy Roman Empire. The decisive contribution in this direction was made by Duke George the Bearded. Two events marked the efforts of the Saxon prince in the public space: the translation into German of the Life of St. Benno, made by Hieronymus Emser in 1517 and the transfer of Benno’s relics in the cathedral of Meißen in 1524. During the Reformation, the cult of St. Benno was called upon to oppose Protestantism. Paradoxically, however, he was able to play his role as a link between the dynasty and subjects only in Bavaria from the end of the 16th century.
V. Jagić and ukrainian question: The letter to F. E. Korsch
Authors:   Institute of World History, Russian Academy of Sciences, Bukharin Mikhail Dmitrievic
Published: September 2023

One of the key-points of the socio-political discourse in the Russian Empire in the XIX ‒ early XX centuries was Slavic question. Ukrainian question was its particular manifestation. The aggravation of discussions on the Slavic issues, as a rule, followed the dynamics of foreign policy. Interest in the Ukrainian issue increased due to the adoption of censorship measures by the Russian state, which varied from tightening to softening of the censorship regime. The Ukrainian question in Russian socio-political thought was debated mainly in the discussion, if the Ukrainian («Little Russian») people represent an independent ethnic group or is a local version of the «Great Russians». Depending on the answer to this question, the ideal structure of the Russian state was going to be worked out. The Imperial St. Petersburg Academy of Sciences took an active part in the discussion of the Slavic question in general (and that of Ukrainian in particular) and in the adoption of appropriate measures, acting as an expert body. Discussions were conducted not only at the institutional level, but also at the private one. In research literature, the scholarly world on this issue is divided into two camps, one of which (liberal-nationalist) was represented mainly by P. B. Struve, and the other — by his numerous opponents (for example, by F. E. Korsh). As documents from the Archive of the Russian Academy of Sciences show, the history of discussion on the Ukrainian issue before the First World War was broader, more scholars, also representing the Academy of sciences were involved. In particular, the position of one the most prominent European Slavist of the late XIX ‒ early XX centuries I. V. Jagić deserves attention. His position on the Ukrainian problem, which worried Jagić for several decades, is especially pronounced in the last letter to F. E. Korsh dated April 9 (22), 1912.
Representation of the Council of ambassadors of the Russian diaspora in Bulgaria (1919–1940)
Authors:   Institute of World History, Russian Academy of Sciences, Mironova Elena Mihaylovna
Published: September 2023

The article is based on materials previously not used in the scientific circulation and highlights the dramatic history of the creation, activities, and closure of the Russian non-bolshevik representation in Bulgaria. The Russian Foreign Diplomatic Corps was the only remnant of the old state apparatus that survived the October Revolution in Russia (1917). The embassy in Sofia became a part of it at the end of 1919, after Bulgaria’s withdrawal from World War I. The article clarifies the circumstances and personal composition of the Representation. The embassy played an important role in the formation of the Russian refugee colony and was closed at the very beginning of 1923. The article identifies the causes of the crisis in relations between the Bulgarian authorities and the embassy, its development, assesses its collapse and shows the hard work that was aimed at preserving the informal non-bolshevik representation. The new representative of the Council of Russian Ambassadors in Bulgaria was B. S. Serafimov. Over two decades he defended the interests of the Russian colony there.

Authors: Henke Ilaria , Pagliara Francesca , Cartenì Armando , Coppola Pierluigi
Published: September 2023

Introduction:

The COVID-19 outbreak has not only had a fatal impact on people's lives, but it has also threatened the entire world of transportation. The number of trips, the mobility habits and the users’ mode choices from the beginning of the pandemic has changed significantly over the last year.

Objective:

This manuscript analyzed the effects of the COVID-19 pandemic on the users’ mobility choices following the pandemic phases during “new normality” was analysed. The objective of this research is twofold: i) to estimate and evaluate the changes in user's mode choices and environmental impact; ii) to identify mobility policies aimed at fostering the use of local Public Transport (PT).

Methods:

A Stated Preference survey was carried out during the COVID-19 pandemic in the city of Naples (South of Italy): i) to assess users’ mobility habits before the COVID-19 pandemic; ii) to evaluate users’ choice of Public Transport after the COVID-19 pandemic period; iii) to identify the attributes related to users’ reluctance (e.g., fear of contagion, service uncertainty) to continue using public transport and the main characteristics that Public Transport should have to be perceived as a safe transport alternative.

Results:

The results show that 56% of users would be willing to wait up to 20 minutes longer for the bus and train to ensure social distancing, especially on reliable info mobility.

Conclusion:

Moreover, 6% of the users, who previously travelled with local PT, would shift to private transport. This means that in the province of Naples, there would be more than 54 million trips by private car with the subsequent effects on congestion and environmental pollution in one month.

Exploring patterns of collaboration among professionals, organisations, patients and communities that meet complex challenges and promote patient well-being
Authors: Haruta Junji
Published: September 2023

Managing the well-being of a super-ageing society requires effective collaboration and communication between professionals, organisations, patients and families. Alongside education and training, the importance of a comprehensive understanding of interprofessional competencies cannot
be understated. Professor Junji Haruta is building on his personal experience as a physician dealing with family illnesses to conduct research that promotes a holistic approach to medicine. He believes primary care professionals will play a crucial role in providing optimal care for the elderly
population in communities for the next 20 years. Haruta is developing resources, including models and theories linked to education on complex issues in primary care, to promote effective interprofessional education. These can be utilised by individuals, universities, organisations and the
wider community as a comprehensive system and facilitate the development of solutions to the increasingly complex challenges associated with healthcare, promoting individual and societal well-being. Haruta employs empirical generalisation, which explores relationships between two or more variables
observed across different conditions and involves collecting findings from various cases and specific contexts to identify patterns. In one study, he and his collaborators investigated the learning process of medical students in an online community diagnostics programme using a realist approach,
which involves theory-driven evaluation, to identify patterns of learning within this programme using the Context (C), Mechanism (M) and Outcome (O) framework. They found that the students acquired knowledge about communities through four distinct learning patterns, and the community diagnosis
programme facilitated a deeper understanding of communities through the application of discovery learning, variation theory and cognitive flexibility theory.

She has written two books providing critical advice on LGBTQ+ issues to educators and counsellors and is transforming how counsellors and educators in Japan view their clients and students. Kasai is currently developing an LGBTQ+ support programme and guidelines for healthcare providers with a view to train counsellors and teachers to be LGBTQ+ sensitive and affirming and, in doing so, create a school environment where children who are struggling with sexuality and gender identity can feel safe. Kasai has developed a novel concept of inter-minority empathy that makes it possible to connect various minorities and resolve conflicts between minorities. The idea is that by improving their familiarity of individuals from sexual orientation and gender identity (SOGI) and other minority groups, people can find connections and similarities with them and better understand other people's experiences and feelings. She found that those who had experienced aggression and negative attitudes were more likely to feel empathy for other minorities who also encountered similar discrimination. Kasai has developed the minority perception scale, which is designed to measure the degree to which people perceive themselves as a minority, and the inter-minority empathy scale, which is designed to measure the degree to which people aware of their own minority status and motivate to support other minorities. Participants were surveyed to discover if they identified with any of 19 demographic categories and found a positive relationship between positive experiences as a minority and inter-minority empathy.
Research on novel HDL cholesterol excretion mechanism
Authors: Tsujita Maki
Published: September 2023

Too much cholesterol can lead to health problems but cholesterol on high-density lipoprotein (HDL-C) is sometimes referred to as `good´ cholesterol because it is inversely related to cardiovascular disease risk. Junior Associate Professor Maki Tsujita, Department of Biochemistry, Nagoya City University, Japan, is leading a team of researchers conducting studies on the novel high-density lipoprotein (HDL) cholesterol excretion mechanism with a view to obtaining new insights on the link between lipid metabolism and diet. Cholesterol biosynthesis involves more than 30 biosynthetic steps and the body has an efficient absorption mechanism to acquire it from the diet via NPC1L1 in the small intestine. The cholesteryl ester transfer protein (CETP) acts as a key recycling mechanism for cholesterol that mediates the equilibrium of cholesteryl esters (CE), limiting cholesterol excretion. The focus of Tsujita's research is on the movement of free-cholesterol molecules and examining its excretion from the body. Tsujita' wants to clarify whether it is CE or free cholesterol that the SR-B1 receptor takes into the cell when it binds HDL, in order to better understand the details of the metabolism of cholesterol. In her current study, she is using a new approach to investigating the origin of free cholesterol in plasma and has found that radiolabelled FCs are increased in SR-BI deficient mice compared to wild-type mice, suggesting that the conversion of CE to FCs is occurring in the blood.
Research and development of demineralised dentin-derived collagen granule bone regeneration materials using animal teeth
Authors: Okubo Naoto
Published: September 2023

The enamel that forms the outer layer of a tooth is the hardest substance in the human body and the structure of the teeth present an opportunity for investigation. For example, Dr Naoto Okubo, who has expertise in dentistry, is interested in the raw material from which the teeth are composed ‐ dentin. Dentin has a special structure known as ` tubules´ that only exists in teeth and can be said to be a communicating porous structure. There is potential that it could be used in the development of new implantable biomaterials. Okubo's current research is exploring whether dentin can be used as a material for building bioregenerative scaffolds. He is based in the Faculty of Pharmaceutical sciences, Department of Molecular and Cellular Medicine, Hokkaido University, Japan, and is Project Leader of the Bovine Demineralized Dentin Matrix (B-DDM) projects. One of the reasons that dentin is suitable as a material for bioregenerative scaffolds is because the most important quality for bioregenerative scaffolds is that they do not interfere with the blood supply when they have been implanted. In addition, it has the strength needed to be used for bioregenerative scaffolds. In their work to use dentin and its tubule structure for the development of bioregenerative scaffolds Okubo and the team are using dentin in such a way that enables them to remove some or all the inorganic components at the same time as maintaining the tissue structure. This means the foundation of the scaffold is mainly composed of type 1 collagen, which has excellent blood permeability and high natural strength.
Impact of neck percutaneous interferential current sensory stimulation on swallowing function in patients with Parkinson's disease
Authors: Nakamori Masahiro
Published: September 2023

Dysphagia is the clinical name for difficulty with swallowing. It can occur with some neurological diseases such as Parkinson's disease and, given the rapidly ageing population, the numbers of patients with Parkinson's disease and dysphagia is on the rise. Despite being quite commonplace, the complex mechanisms of dysphagia mean that the condition is not well understood. Assistant Professor Masahiro Nakamori is a clinical neurologist investigating the mechanisms of neurological disease, with a focus on neurodegenerative diseases and dysphagia. A current focus is on dysphagia and silent aspiration in people with Parkinson's disease. He is based in the Department of Clinical Neuroscience and Therapeutics, Graduate School of Biomedical and Health Sciences, Hiroshima University, Japan. So far, Nakamori has explored several different techniques, including tongue pressure measurement and tongue ultrasonography, which are both used in swallowing evaluation. He is interested in non-invasive techniques that are simple to implement and wants to develop new creative instruments and techniques. In his current research, Nakamori and his collaborators are experimenting with multichannel surface electromyogram to gain a comprehensive understanding of neuromuscular activity. The goal is to develop new techniques and instruments that will help advance clinical neurology and dysphagia research and, of course, benefit patients; improving outcomes and quality of life.
Detailed muscle state analysis method based on real-time wavelet analysis of surface myoelectric potential
Authors: Nagai Hidetoshi
Published: September 2023

Myoelectric refers to the use of electricity generated by muscles and is harnessed in the development of electrically powered prostheses, which are controlled by electromyographic (EMG) signals created in the residual musculature. Assistant professor Hidetoshi Nagai, Department of Artificial
Intelligence, Kyushu Institute of Technology, Japan, is interested in surface myoelectric signals and is working on a project to develop technology that can advance their use. Nagai will capture motor unit activities using surface electromyography, which is easy to measure during exercise,
and use this as the basis for more detailed muscle activity analysis. The methods Nagai has developed require no special equipment, other than the ability to sample at frequencies of several tens of kHz, and only require a single channel, which indicates the potential for more sophisticated
analysis when multiple channels of information are present. It is also a simple and lightweight process that can be executed in real time. Conventional analysis and evaluation of muscle activity cannot be performed from the perspective of motor unit activity but Nagai has built on the basic
premise that given that muscle activity is the sum of motor unit activities, the analysis of muscle activity should be based on the analysis of motor unit activity. He will analyse the surface EMG signal from the viewpoint of its component waveform the motor unit waveform so that muscle activity
analysis can be performed as it should be.
Site determination and application of LTBP-1, a molecule related to atherosclerosis, involved in cell migration
Authors: Mimori Seisuke
Published: September 2023

The two strands of treatment available for coronary artery disease and associated pathologies are pharmaceutical and physical. However, these treatments are typically only available too late to help tackle the early underlying processes. Better understanding of the underlying processes
is key to the development of preventative solutions. One of the key processes understanding coronary problems is atherosclerosis, which is when arteries lose elasticity. Associate Professor Seisuke Mimori, Department of Clinical Medicine, Chiba Institute of Science, Japan, is examining the
underlying biochemistry of atherosclerosis. Professor Tetsuto Kanzaki has succeeded in cloning a protein called LTBP-1 and, under his direction, Seisuke has created a mutant of the protein and is analysing it. He intends to produce variants of LTBP-1 in order to investigate the function of
various domains of the protein. This will involve firstly producing and isolating the protein and its variants in sufficient quantities. Then, he will test cell migration rates through an assay that he and the team have designed. This will enable the researchers to clarify exactly how LTBP-1
functions. In the future, Seisuke and the team will investigate the exact mechanism of action of the domains involved and explore the impact of LTBP-1 on the relevant organs and cells.
