Published: October 2023

The association between vaccines and ocular disorders has attracted significant attention in scientific research. Numerous mainstream vaccines are associated with a range of uveitis types, including anterior, intermediate, and posterior uveitis. Additionally, they are associated with distinct ocular diseases such as multifocal choroiditis, Vogt–Koyanagi–Harada (VKH) disease, acute posterior multifocal placoid pigment epitheliopathy (APMPPE), and multiple evanescent white dot syndrome (MEWDS). These ocular conditions are often transient, with a vast majority of patients experiencing improvement after steroid intervention. To date, numerous cases of vaccine-induced uveitis have been reported. This study analyzed the correlation between antiviral vaccines, including the hepatitis B virus (HBV), human papillomavirus (HPV), measles–mumps–rubella (MMR), varicella zoster virus (VZV), and influenza vaccines, and different manifestations of uveitis. This is the first comprehensive study to offer a detailed analysis of uveitis types induced by antiviral vaccines. Through an extensive database search, we found a particularly strong link between influenza vaccines, followed by VZV and HPV vaccines. While anterior uveitis is common, conditions such as APMPPE, MEWDS, and VKH are particularly notable and merit careful consideration in clinical practice. Corticosteroid treatment was effective; however, half of the observed patients did not achieve full recovery, indicating potentially prolonged effects of the vaccine.

Published: October 2023

Copper (Cu), zinc (Zn), and nickel (Ni) are essential micronutrients for aquatic life, but they produce adverse effects on aquatic organisms when environmental concentrations exceed a certain threshold. The objective of this study was to analyze the taxon-specific sensitivities of aquatic life to the three metals and assess ecological risks at exposure levels prevalent in the Songhua River, China. The results showed that sensitivities to these metals varied among different taxonomic groups, with intra-taxon sensitivities being lower than inter-taxa sensitivities, and the consistency of intra-taxon sensitivity increased from phylum to order. The maximum detected concentrations of Cu, Zn, and Ni in the Songhua River were 52.7, 166.0, and 65.3 μg/L, respectively, which met the water quality standards set by China but exceeded the chronic criteria established by the USA. A probabilistic risk assessment based on chronic toxicity data revealed that these three metals posed an intermediate to high risk to aquatic animals, with maximum risk products of 36.4% for Cu, 14.3% for Ni, and 6.2% for Zn, respectively. These results indicate that the ecological damage of heavy metals in the Songhua River cannot be ignored.
Exploration of Applicability of Diatom Indices to Evaluate Water Ecosystem Quality in Tangwang River in Northeast China
Authors: Xue Hao , Wang Lei , Zhang Lingsong , Wang Yeyao , Meng Fansheng , Xu Min
Published: October 2023

The diatom index has been widely used in the evaluation of water ecological quality, but the applicability of the diatom index often varies in different study areas. The accuracy of the evaluation results depends on the applicability of the diatom index, especially when it is not applied to the place where it is created. In order to screen out the diatom index suitable for the evaluation of the water ecological quality of Tangwang River in northeast China, and to identify the factors affecting the accuracy of the diatom index, the community structure and water environment characteristics of 24 sample sites were investigated in Tangwang River in August 2018, and 18 diatom indices were calculated. The discriminative ability of diatom indices was analyzed using the box plot method, and the factors affecting the accuracy of the diatom index were identified by combining Pearson and Spearman correlation analyses. The results show that the discriminability of the Biological Diatom Index (BDI), Specific Pollution Sensitivity Index (IPS), Idse Leclercq (IDSE), Indice Diatomique Artois Picardie (IDAP), Diatom Eutrophication Pollution Index (EPI-D), Trophic Index (Rott TI), European Economic Community Index (CEE), and Watanabe Index (WAT) was the strongest, which could reasonably distinguish the reference group from the lightly damaged group. In general, the water ecological condition of Tangwang River Basin is good in the wet season, and the water ecological quality of about 80% of the sample sites was “moderate” or better. The main factors affecting the evaluation accuracy of the diatom index in Tangwang River Basin are the correlation strength between the diatom index and habitat quality, organic pollution, and nutrients. The coverage of diatom index species had no significant effect on the accuracy of evaluation. In order to reasonably evaluate the aquatic ecological status, it is recommended to use the diatom index, which has a good correlation with the environmental factors in the study area, or to establish a new diatom index based on the diatom community and environmental factors in the study area.
Flux Vector Splitting Method of Weakly Compressible Water Navier-Stokes Equation and Its Application
Authors: Li Heng , Huang Bingxiang
Published: October 2023

Water is a weakly compressible fluid medium. Due to its low compressibility, it is usually assumed that water is an incompressible fluid. However, if there are high-pressure pulse waves in water, the compressibility of the water medium needs to be considered. Typical engineering applications include water hammer protection and pulse fracturing, both of which involve the problem of discontinuous pulse waves. Traditional calculation and simulation often use first-order or second-order precision finite difference methods, such as the MacCormark method. However, these methods have serious numerical dissipation or numerical dispersion, which hinders the accurate evaluation of the pulse peak pressure. In view of this, starting from the weakly compressible Navier–Stokes (N-S) equation, this paper establishes the control equations in the form of flux, derives the expressions of eigenvalues, eigenvectors, and flux vectors, and gives a new flux vector splitting (FVS) formula by considering the water equation of state. On this basis, the above flux vector formula is solved using the fifth-order weighted essentially non-oscillatory (WENO) method. Finally, the proposed FVS formula is verified by combining the typical engineering examples of water hammer and pulse fracturing. Compared with the traditional methods, it is proved that the FVS formula proposed in this paper is reliable and robust. As far as we know, the original work in this paper extends the flux vector splitting method commonly used in aerodynamics to hydrodynamics, and the developed model equation and method are expected to play a positive role in the simulation field of water hammer protection, pulse fracturing, and underwater explosion.

Authors: Dziubak Kateryna
Published: October 2023

The article is devoted to the study of the organizational and legal boundaries of the provision of scientific and expert activities in administrative proceedings, as defined in the Code of Administrative Procedure of Ukraine. The possibility of involving an expert in the field of law in the administrative process through the conduct of scientific and legal expertise, one of the functional purposes of which is the doctrinal interpretation of legislation, is considered. The problem of determining the competence of an expert in the field of law is consecrated and the criteria for its evaluation are presented. The necessity of improving the norms of the specified code of Ukraine in terms of determining the procedural rights and obligations of an expert in the field of law in a trial, as well as the legal nature of his conclusion, is proved. In particular, we consider it necessary, along with the requirement fixed by the legislator to have a scientific degree and be a recognized specialist in law, to add such a requirement as a mandatory practical experience as a lawyer for at least 10 years. Proposals are provided on amending the Code of Administrative Procedure of Ukraine, which will help resolve conflicts in the current legislation regarding the legal status of an expert in the field of law and the opinion provided by him, his rights and obligations.
TOPICAL ISSUES OF PROTECTING THE RIGHTS AND LEGITIMATE INTERESTS OF THE ACCUSED IN CORRUPTION CRIMINAL PROCEEDINGS INVOLVING CONFIDANTS (REGARDING THE PROCEDURE FOR ATTRACTING A CONFIDANT BY AN AUTHORIZED ENTITY)
Authors: Malenko Oleksandr
Published: October 2023

In the scientific article, the author examines the theoretical and practical problems of the procedure for the investigator’s involvement of a person in confidential cooperation and conducting covert investigative (search) actions during the pre-trial investigation of corruption criminal proceedings. It also reveals the issue of the use by the defence side of the established violations in the algorithm of involving the relevant person in criminal proceedings in order to justify the inadmissibility of evidence obtained as a result of covert investigative (search) actions with the participation of the confidant.
Based on the analysis of the judicial practice of the High Anti-Corruption Court and the Appeals Chamber of the High Anti-Corruption Court, the author concluded that there is no uniform application of Article 275 of the Criminal Procedure Code of Ukraine in the activities of law enforcement agencies. Most often, investigators attract confidants by selecting an application for voluntary consent to confidential cooperation and participation in covert investigative (search) actions and the adoption of a corresponding resolution. There are cases of a decision on the participation of a confidant in criminal proceedings by the prosecutor when adopting a resolution on the conduct of covert investigative (search) actions – control over the commission of a crime (with the written consent of the person). The author has researched judicial practice in cases where the materials of criminal proceedings do not contain any procedural documents regarding the involvement of a confidant in covert investigative (search) actions and confidential cooperation.
The article stated the fact that the High Anti-Corruption Court and the Appels Chamber of the High Anti-Corruption Court ignored all violations of the prosecution regarding the implementation of Article 275 of the Criminal Procedure Code of Ukraine.

The publication is devoted to the scientific analysis of the criteria for evaluating the testimony of the participants in criminal proceedings at the trial stage. It has been established that the court is the only subject of evaluation of testimony of participants in criminal proceedings as an element of the proof process in the court of first instance. It was concluded that the evaluation of the evidence, in particular those contained in the testimony, from the point of view of propriety, admissibility, and reliability is carried out in relation to each investigated evidence and as a result creates a holistic perception of the circumstances of the criminal offense based on the entire volume of collected evidence.
ONE OF THE APPROACHES TO SOLVING THE PROBLEM OF ESTABLISHING THE CHRONOLOGICAL SEQUENCE OF PERFORMING ELECTROGRAPHIC AND HANDWRITTEN DETAILS IN THE ABSENCE OF PLACES OF THEIR MUTUAL INTERSECTION
Authors: Kulykovska Viktoriia
Published: October 2023

Long-term expert practice indicates that the filling of a number of documents has a strictly regulated, often violated order.
In the article, the author points out the relevance in modern technical and forensic examination of documents of solving the issue of chronological drawing of strokes of the details of the document (study of the sequence of their implementation), since most often the solution of this particular issue is the only way to establish the truth about the validity or falsification of the document. Taking into account the changes in the writing materials (the addition of new and constant improvement of existing recipes) occurring in modern production, it is necessary to constantly update existing and create new methods for solving this problem.
The author pointed out significant progress in the direction of applying a technique based on the use of modern capabilities of optical microscopes and embedded systems for visualization and digital registration of a picture that is observed under a microscope, taking into account the printing process of devices with laser printing technology, in which toner is used to transfer the image to paper. powder, laser beam and static electricity.
The article considers an approach to the application of the method of establishing the sequence of execution of the details of documents, one of which is made by the method of electrophotography in the absence of places of their mutual cross-section. The analysis of the results obtained in the course of expert studies is presented. The scheme algorithm of the conducted experimental studies is described and a logical chain of established facts is built. The illustrations of the results of the conducted research are given.
It is indicated in the article, which continues the study of the details obtained by the electrophotographic method on different brands and models of laser devices, as well as the quantitative dependence of toner microparticles within a stroke on the depth of the relief from the writing instrument assembly.
The author of the article notes that even in the presence of the instrumental base, methodically competent development of the conditions of application is required, and in general, conducting expert research requires the expert not only to have knowledge of existing research methods but also the ability to correctly evaluate the results obtained.

Authors: Prykhodko Yurii , Ivasychyn Taras , Kulchytskyi Andrii , Munchak Volodymyr
Published: October 2023

The peculiarity of the issues discussed in this article is the study of situational expertise as a type of forensic research. The team of authors consider situational forensic expertise in terms of explosives expertise because this type of research is quite specific.
Practice shows that not all participants in the criminal process equally understand the importance of studying the issue related to the situational explosive expertise. There are many examples of errors in the appointment of situational explosive technical expertise, in solving questions by experts during the performance of this type of expertise. However, the most difficult issue is the collection and provision of objects (materials) for expert research. Special attention should be paid to this because based on the results of the situational study, the court makes an important decision on the punishment of the guilty.
Carrying out the analysis of the current state of situational expert studies in the sense of appointing and conducting forensic explosive expertise will improve the quality of the investigation of crimes related to the use of explosive devices, ammunition and explosives.
The article determines that a feature of the situational explosive expertise is that by its nature, in most cases, it should be a comprehensive forensic expertise. When conducting situational explosive expertise, the results of investigative (search) actions related to the study of the situation at the scene of the incident should be taken into account. The subject of situational explosive expertise is incidents specifically related to the subject of confirmation. Situational explosive expertise is distinguished by the complex and multi-stage nature of the tasks being solved, determined by the specific features of the objects of study, which are multi-component events.
Situational explosive expertise is carried out on the basis of the versions put forward by the investigation and the court. When conducting a situational explosive expertise, the results of an inspection of the scene of the incident are used, and in most cases of other investigative (detective) actions, including an investigative experiment, the conclusions of experts regarding previously conducted forensic expertise are taken into account.

Authors: Sadchenko Oleksandr , Kulchytskyi Andrii , Stepaniuk Oleksii
Published: October 2023

The article emphasizes the importance of developing, on the basis of scientific and legislative terminology, the terminology of explosive expertise and substantiates the relevance of the creation and systematization of terminologies. modern expert terminology in forensic explosive examination with subsequent representation in the DSTU (State National Standard of Ukraine) «Forensic explosives examination. Terms and Definitions».
In the process of forming terminology for explosives expertise, the identified trends are investigated, the main of which is the unconditional restoration of the terminology of the 80-90s of the last century, which does not contribute to the replacement of established terms in forensic explosives.
The second negative trend is the subjectivity and randomness in the selection of terms for the terminological system, as a result of which many necessary and important terms for explosives expertise, as well as other branches of knowledge, do not fall into them.
The proposed terminology creation technique is implemented in each algorithm:
– selection of terms in the DSTU (State National Standard of Ukraine) /glossary should be carried out taking into account the frequency of their use in scientific papers;
– the composition of the DSTU (State National Standard of Ukraine)/glossary should be formed in accordance with the needs of expert, investigative and judicial practice;
– the order of placement of terms should correspond to their convenient and quick finding;
– the method of describing expert terminology must correspond to the type of
(State National Standard of Ukraine) /glossary;
– the terminological apparatus of explosive examination should reflect the innovative processes of development of the theory and practice of forensic
examination;
– terms should reveal the essence of the concept and comply with the norms and rules of the modern literary Ukrainian language.
The experience of the terminological work of the Kyiv Scientific Research Institute of Forensic Expertise of the Ministry of Justice of Ukraine on the implementation of terminological work on various types of forensic examinations is highlighted.
As a rule, the authors combined practical work on the conclusion of a terminological standard with a theoretical understanding of the construction of terminological systems. A methodology for unified expert terminology is proposed, in which the main methodological and scientific principles for constructing a terminological standard were determined.
FEATURES OF PERFORMING EXPERT STUDIES OF MAGNETIC FIELD INDICATORS AS A MEANS OF IDENTIFYING THE IMPACT ON METERING DEVICES OF AN EXTERNAL MAGNETIC FIELD CREATED FOR THE PURPOSE OF UNACCOUNTED CONSUMPTION OF ENERGY RESOURCES
Authors: Rohalin Serhii
Published: October 2023

The study of the facts and circumstances of the unaccounted use of energy resources by consumers, primarily electric energy, natural gas, hot and cold water in the practice of conducting electrical and heat engineering types of forensic examinations, is one of the most common. The initial data in forensic research in this area, namely the data of acts on the violation of the consumption of these energy resources, including information on fixing the impact on the metering device of a constant magnetic field by magnetic field effect indicator (MFEI), which in the cases under study is usually denied by the consumer as his intentional actions to create such a field. The expert task of forensic examinations in this area requires an unambiguous definition of the operation of a MFEI from a constant magnetic field with certain power characteristics, with the exclusion of other factors of influence.
The most common modern designs of magnetic field impact indicators in use, which are installed by energy sales enterprises as fixing technical means of interfering with the operation of consumer metering devices when using energy resources as a result of exposure to an external constant magnetic field, are considered. The triggering mechanism of MFEI of different designs is analyzed. According to the constructive construction and principle of operation, the indicators of the influence of the magnetic field are divided into separate classification groups. Signs of atypical triggering of the MFEI are considered. Cases of activation of indicators of the impact of the magnetic field are determined, requiring a comprehensive study using research methods of various forensic specialties to establish the fact of interference in the operation of metering devices in order to unaccounted for the consumption of energy resources.
Recommendations are given on the application of the method of modeling a constant magnetic field with the reproduction of the conditions for the operation of the investigated MFEI to establish the fact of interference in the operation of the meter by exposing it to an external constant magnetic field in order to unaccounted for the consumption of energy resources. The necessity of performing a check of the operable state of the MFEI in expert experience in the study of the fact of the existence of the influence of a constant magnetic field on the metering device for energy consumption is substantiated.

CONDUCTING A PSYCHOLOGICAL RESEARCH OF PRISONERS
Authors: Zhuravlova Marharyta , Rudakova Viktoriia
Published: October 2023

The article is devoted to the analysis of difficulties arising in the work of expert psychologists when conducting research on persons serving sentences in prisons or in pre-trial detention centres (prisoners). The ways to overcome such difficulties are proposed in order to minimize the possible risks in the process of interaction between an expert psychologist and prisoners, which may cause significant psychological barriers during the process of their communication and create obstacles in the expert examination by psychologists with little experience in this very work.
The article outlines the psychological tools and steps that an expert psychologist can use in their work, such as:
1) informing the examinee about what exactly will happen during the
psychological examination
2) take into account the conditions of arrival (escort) of the prisoner for
psychological examination
3) using the open position of the expert
4) using interest to get the person under investigation motivated
5) taking into consideration the prisoner’s attempts to influence and form an
appropriate role position from the side of the psychologist
6) Using atypical diagnostic tools during the process of testing a prisoner’s person.
It is considered that the examination of persons with a certain criminal experience and who are in prison differs significantly from the examination of other examinees in terms of the conditions of diagnostic interview and testing. The negative position of a prisoner to the test, the conditions of arriving for the examination, and the reluctance to open up in the situation of the test can greatly complicate the work of a psychological expert.
The article highlights and identifies the issue that the decisive factor in conducting a psychological examination of prisoners is not the general training of the expert or the ability to use diagnostic tools, but the capacity to get the prisoner’s trust even in difficult conditions, to make the prisoner feel safe in communicating with the psychologist, and to maintain the sub-expert’s interest in undergoing the examination throughout the entire process of diagnostic interaction.

Authors: Stadnik Iryna
Published: October 2023

Judicial consideration of family disputes, in which the interests of the child are affected, is particularly difficult, since in its course not only controversial issues between parents and other persons are resolved, but also the fate of the child is determined. The key in expert practice in this matter remains the reluctance or inability of parents to understand the full depth of the traumatic situation in which their child falls, reacting to the emotions and actions of their parents.
In the process of writing the article, general scientific methods of analysis, synthesis, grouping and logical generalization were used in order to theoretically study the existing practices and own experience of expert research and to form the key directions of the work of a forensic expert in family conflicts.
The current experiences, feelings and emotions of children who, after the divorce of their parents, remain living with one of them, but constantly suffer from the unsatisfied ambitions of the other parent with whom the child does not live, are considered. In the example of specific children and the family situations in which they found themselves, the negative impact of factors and situations, in particular, questioning of children within the framework of a court session, forcibly depriving a child of the opportunity to choose a place of residence, limiting contacts and meetings with one of the parents on the psychological development of the child, was analyzed, formation of the child’s attitude towards himself and the surrounding world, determination of the direction of his social contacts in the future. Established regularities of children’s behavioural characteristics, in accordance with modern ideas about the driving forces, sources and conditions for the development of the psyche of the individual – the child’s mental development is mediated by communication and interaction with adults, and first of all, with parents. The child’s emotions, feelings and attachment to his parents, his real desire to live with one of them, taking into account the child’s opinion and inner desire when choosing a place of residence are determined. It is established that a differentiated approach should be used when choosing a place of residence, the child should not experience traumatic experiences and feelings of guilt, choosing one of the parents to whom he feels more attached at the moment.

Authors: KOLDAMCA YILMAZ Merve , KELEŞ Nurseza , ŞENYILDIZ Anastasia
Published: October 2023

Die vorliegende Arbeit setzt sich zum Ziel, die Vorstellungen türkischer DaF-Studierender von der Lehrkraftrolle im digitalen Zeitalter anhand von Metaphern zu analysieren. Es handelt sich um eine Fragebogenuntersuchung mit 57 Studierenden des dritten und vierten Studienjahres der DaF-Lehramtsabteilung an einer türkischen Universität. Erkenntnisleitend waren dabei die Fragen, welche Metaphern die Studierenden zur Beschreibung von Lehrkräften mit entwickelten digitalen Kompetenzen benutzen und welchen Kategorien die von ihnen verwendeten Metaphern zugeordnet werden können. Im Fragebogen füllten die Probanden und Probandinnen den Satz „Eine mit digitalen Lernanwendungen arbeitende DaF-Lehrkraft ist wie …, weil …” aus. Außerdem wurde eine Frage vom Likert-Typ zur Relevanz des Einsatzes digitaler Lernanwendungen benutzt. Die Analyse der Antworten ergab, dass eine überwiegende Mehrzahl der Befragten die Verwendung von digitalen Lernanwendungen für sehr wichtig (70,2 %, n = 40) und wichtig (24,6 %, n = 14) hielt. Des Weiteren nutzten 16 von den 57 Teilnehmenden in ihren Antworten keine Metaphern, deswegen konnten nur 41 Antworten bei der Auswertung von Metaphern berücksichtigt werden. Insgesamt wurden 33 unterschiedliche Metaphern zur Umschreibung von einer mit digitalen Lernanwendungen arbeitenden DaF-Lehrkraft benutzt. Die qualitative Inhaltsanalyse der Daten führte zur Bildung folgender Kategorien: „Innovator“, „Entertainer“, „wertvolles Objekt“, „Unterrichtsmanager“, „Motivationstrainer“ und „Aufmerksamkeitslenker“. Im Vergleich mit den Metaphern-Untersuchungen zum traditionellen Lehrkraftbild verdeutlichen unsere Kategorien die sich verändernde Lehrkraftrolle im digitalen Zeitalter, in der nicht mehr die Wissensvermittlung, sondern Innovation, Lernen mit Spaß sowie Motivation im Vordergrund stehen.

Authors: ŞİMŞEK Yücel
Published: October 2023

The main aim of this research is to examine the role of smartphone addiction in the relationship between perceived parental and teacher academic involvement and academic procrastination behavior among middle school students. The data for the research were collected from 590 students who study in middle schools in Odunpazarı district of Eskişehir through personal information forms and scales. The scales used in the study consist of items that inquire about the levels of perceived parental and teacher academic involvement, academic procrastination behavior and smartphone addiction of the students. In line with the aims of the research, the data were analyzed using the SPSS 22.0 package program. Descriptive statistics, correlation analysis and regression analysis were used to answer the research questions. According to the results obtained from the study, it was determined that middle school students’ levels of perceived parental and teacher academic involvement were above average, their levels of smartphone addiction were below average and finally their frequency of academic procrastination behavior was below average. As a result of the study, it was determined that there were negative and statistically significant relationships between perceived parental and teacher academic involvement and the academic procrastination behavior of students. As a result of the regression analyses conducted for the main purpose of the research, it was revealed that smartphone addiction partially mediated both the effect of perceived parental academic involvement on academic procrastination behavior and the effect of perceived teacher academic involvement on academic procrastination behavior. Within the scope of the study, it was suggested to examine other possible variables that may cause academic procrastination behavior, which is one of the most important factors that negatively affect student success.

Published: October 2023

Background: This study was to describe the magnetic resonance imaging (MRI) features of cervical spondylosis, to evaluate the relation between MRI images and other factors.

Materials and Methods: This is a cross-sectional study with convenience sampling and was carried out at Hue University of Medicine and Pharmacy Hospital between June 2019 and November 2022. We recruited 184 patients who were diagnosed with cervical spondylosis by clinical symptoms, X ray and MRI images.

Results: MRI images of cervical spondylosis were seen most frequently at C4, C5, C6. Approximately 84% of patients had spinal cord stenosis, the ones who had compression images accounted for 50.7%. Cervical neural foraminal stenosis (CNFS) with compression (48.4%) and herniated disc (75%) were found most common at C5-C6 level. There were statistically-significant relations between cervical radiculopathy syndrome and the root compression images on MRI, between cervical myelopathy syndrome and spinal cord signal changes on MRI.

Conclusion: Patients with cervical spondylosis symptoms should undergo X-ray and MRI of the cervical spine to get a comprehensive morphological assessment of lesions.

Backgrounds: Candida is the most common causative agent of oral thrush, especially in patients with chronic diseases.

Objectives: 1. To determine the prevalence of oral Candida infection in patients undergoing internal medicine treatment. 2. To survey clinical symptoms and associated factors of oropharyngeal candidiasis.

Materials and methods: A cross-sectional study of 213 patients was performed. Patients with oral candidiasis were assessed and recorded for clinical symptoms and associated factors. Oral mucosal swabs were collected and examined with KOH 20% for determining yeast-positive samples. The positive samples were subsequently cultured on chromogenic agar to identify fungal species.

Results: The rate of oral Candida infection was 16.9%. The prevalence of C. albicans and C. non albicans was 55.6% and 44.4%, respectively. Clinical signs of oropharyngeal candidiasis were dysgeusia and anorexia (47.2%), burning sensation (5.6%), creamy-white plaques (30.6%), and angular cheilitis (2.8%). Factors that favor fungal infection included: Age 60 or older, saliva pH < 7, inability to self-care, brushing teeth less than twice daily, underweight, chronic obstructive pulmonary disease, respiratory and urinary tract infections, use of inhaled corticosteroids, antibiotic therapy, combination of antibiotics, antibiotics therapy of more than seven days.

Conclusion: Oral thrush should be considered in hospitalized patients with risk factors in clinical practice so that patients can be diagnosed and treated early

A Friction-Driven Strategy for Agile Steering Wheel Manipulation by Humanoid Robots

Published: October 2023

Vehicle driving can substantially enhance the maneuverability of humanoid robots. Agile steering wheel manipulation requires rapid rotation in narrow spaces such as a cab, serving as the foundation for increasing driving speed, especially in an obstacle avoidance scenario. Generally, there are 3 human driving strategies, “Hand-to-Hand,” “Hand-over-Hand,” and “One-Hand.” Based on the human driving motion data, we quantitatively analyze these strategies from 3 aspects, motion range of joint combination, motion region of the shoulder, and velocity of the manipulation. Then, a friction-driven manipulation strategy using one hand is proposed utilizing the similarity between a humanoid robot and a driver (human). It effectively addresses the requirements of both a small range of motion and rapid manipulation. To prevent the deformation of the steering wheel caused by excessive force, we construct an operating force model specifically for the steering wheel. This model accurately describes the relationship between the rotation resistance and the state of the steering wheel. In addition, we propose a quadratic programming (QP)-based control framework to servo the robot to track the end-effector position and target wrench output by this model. Finally, the effectiveness of this paper is evaluated through an obstacle avoidance scenario, achieving a maximum rotation velocity of 3.14 rad/s.

Brain–computer interface (BCI) decodes and converts brain signals into machine instructions to interoperate with the external world. However, limited by the implantation risks of invasive BCIs and the operational complexity of conventional noninvasive BCIs, applications of BCIs are mainly used in laboratory or clinical environments, which are not conducive to the daily use of BCI devices. With the increasing demand for intelligent medical care, the development of wearable BCI systems is necessary.
Highlights:
Based on the scalp-electroencephalogram (EEG), forehead-EEG, and ear-EEG, the state-of-the-art wearable BCI devices for disease management and patient assistance are reviewed. This paper focuses on the EEG acquisition equipment of the novel wearable BCI devices and summarizes the development direction of wearable EEG-based BCI devices.
Conclusions:
BCI devices play an essential role in the medical field. This review briefly summarizes novel wearable EEG-based BCIs applied in the medical field and the latest progress in related technologies, emphasizing its potential to help doctors, patients, and caregivers better understand and utilize BCI devices.
