IntroductionIn the middle of December 2022, the Chinese government adjusted the lockdown policy on coronavirus disease 2019 (COVID-19), a large number of infected patients flooded into the emergency department. The emergency medical staff encountered significant working and mental stress while fighting the COVID-19 pandemic. We aimed to investigate the workload change, and the prevalence and associated factors for depression symptoms among emergency medical staff after the policy adjustment.MethodsWe conducted a cross-sectional online survey of emergency medical staff who fought against COVID-19 in Shandong Province during January 16 to 31, 2023. The respondents’ sociodemographic and work information were collected, and they were asked to complete the 9-item Patient Health Questionnaire (PHQ-9) then. Univariate and multivariate logistic regression analyses were applied to identify the potential associated factors for major depression.ResultsNine hundred and sixteen emergency medical personnel from 108 hospitals responded to this survey. The respondents’ weekly working hours (53.65 ± 17.36 vs 49.68 ± 14.84) and monthly night shifts (7.25 ± 3.85 vs 6.80 ± 3.77) increased after the open policy. About 54.3% of the respondents scored more than 10 points on the PHQ-9 standardized test, which is associated with depressive symptoms. In univariate analysis, being doctors, living with family members aged ≤16 or ≥ 65 years old, COVID-19 infection and increased weekly working hours after the open policy were significantly associated with a PHQ-9 score ≥ 10 points. In the multivariate analysis, only increased weekly working hours showed significant association with scoring ≥10 points.ConclusionEmergency medical staff’ workload had increased after the open policy announcement, which was strongly associated with a higher PHQ-9 scores, indicating a very high risk for major depression. Emergency medical staff working as doctors or with an intermediate title from grade-A tertiary hospitals had higher PHQ-9 scores, while COVID-19 infection and weekly working hours of 60 or more after the open policy were associated with higher PHQ-9 scores for those from grade-B tertiary hospitals. Hospital administrators should reinforce the importance of targeted emergency medical staff support during future outbreaks.

IntroductionEccentric exercise has often been reported to result in muscle damage, limiting the muscle potential to produce force. However, understanding whether these adverse consequences extend to a broader, functional level is of apparently less concern. In this study, we address this issue by investigating the acute and delayed effects of supramaximal isotonic eccentric exercise on neuromuscular function and motor performance of knee extensors during tasks involving a range of strength profiles, proprioception, and balance.MethodsFifteen healthy volunteers (23.2 ± 2.9 years old) performed a unilateral isotonic eccentric exercise of the knee extensors of their dominant lower limb (4 × 10 reps at 120% of one Repetition Maximum (1RM)). The maximum voluntary isometric contraction (MVC), rate of force development (RFD), force steadiness of the knee extensors, as well as knee joint position sense and mediolateral (MLI) and anteroposterior stability (API) of the dominant lower limb, were measured pre-, immediately, and 24 h after the eccentric exercise. The EMG amplitude of the vastus medialis (VM) and biceps femoris (BF) were concomitantly evaluated.ResultsMVC decreased by 17.9% immediately after exercise (P &lt; 0.001) and remained reduced by 13.6% 24 h following exercise (P &lt; 0.001). Maximum RFD decreased by 20.4% immediately after exercise (P &lt; 0.001) and remained reduced by 15.5% at 24 h (P &lt; 0.001). During the MVC, EMG amplitude of the VM increased immediately after exercise while decreasing during the RFD task. Both values returned to baseline 24 h after exercise. Compared to baseline, force steadiness during submaximal isometric tasks reduced immediately after exercise, and it was accompanied by an increase in the EMG amplitude of the VM. MLI and knee joint position sense were impaired immediately after isotonic eccentric exercise (P &lt; 0.05). While MLI returned to baseline values 24 h later, the absolute error in the knee repositioning task did not.DiscussionImpairments in force production tasks, particularly during fast contractions and in the knee joint position sense, persisted 24 h after maximal isotonic eccentric training, revealing that neuromuscular functional outputs were affected by muscle fatigue and muscle damage. Conversely, force fluctuation and stability during the balance tasks were only affected by muscle fatigue since fully recovered was observed 24 h following isotonic eccentric exercise.
COMPOSITION AND STRUCTURE OF HYDROPHYTE COMMUNITIES IN DIFFERENT TYPES OF WATER BODIES IN THE CITY OF POLTAVA
Authors: Klepets O. 
Published: November 2023

The article highlights the results of studying the composition and structure of the true aquatic plant communities in different types of water bodies of the city of Poltava (artificial and natural reservoirs, the urban section of the middle River Vorskla), where, according to the ecological and floristic classification, 21 associations (including 8 subassociations) of eight alliances, three orders and two classes were identified. Of these, only association Ceratophylletum demersi is the most typical in urban area. The class POTAMETEA differs in the relatively higher coenotic diversity (13 associations), and the class LEMNETEA differs in the lower diversity (8 associations).
The studied plant associations are characterized by a low species richness, the absolute majority of them represents a simplified version of the original natural associations. Communities of class POTAMETEA, observed in urban reservoirs, are especially depleted (1–3 species in the descriptions). There is a general tendency to increase the coenotic activity of the floristic elements that are tolerant to anthropogenic load and eutrophication.
In the rank of associations there are 18 communities in urban lentic water bodies and 9 communities on the urban section of the middle river. Most of the identified associations (12) are confined exclusively to urban reservoirs, while only 3 associations are specific to the urban section of the river. Of those 6 associations found both in urban reservoirs and in the urban section of the middle river, it is the river coenoses that are more diverse and better developed.
In the conditions of an urbanized environment, the middle river ecosystems show a higher resistance to anthropogenic influence compared to ecosystems of artificial urban water bodies, which is evidenced, in particular, by a more complex coenotic structure of common associations, as well as the presence of sozologically valuable communities specifically in the river hydroecotopes.
PECULIARITIES OF THE STRUCTURE OF THE INTRAHEPATIC BILE DUCTS OF HERBIVOROUS MAMMALS

Published: November 2023

Pathology of the organs of the hepatobiliary system, which happens in the form of calculous and non-calculous cholecystitis, cholangitis of various etiologies and other diseases of the biliary system, occupies one of the first places among surgical interventions on the organs of the abdominal cavity.
Among the adult population, about 10% of those able to work suffer from gallstone disease. This disease is spreading in all countries of the world, and the tendency to its increase is growing. Such an increase in the pathology of the biliary tract is also observed in economically developed countries. Observations show that men suffer less often than women.
The structure of the wall of the intrahepatic ducts is represented by the inner mucous membrane and the outer adventitia membrane. But the structure of their wall in different parts of the liver has its own characteristics. At the beginning of the intraciliary system of the liver, the mucous membrane is represented by epitheliolytic, which have a cubic shape.
The outer shell is represented by cells of the fibroblastic series. In the average department of the internal biliary system of the liver, there is an increase in the size and number of cells in the inner lining of the ducts. Nuclei in the initial division change shape to a bean-like one. Changes in the inner membrane are observed in the terminal part of the intraciliary system of the sheep’s liver. Cells become prismatic and folds can be observed on their apical surface. Nuclei are localized on the basal surface and have a bean-like shape.

Published: November 2023

This article deals with the publication and the comparative analysis of the 17th – 18th cent. female cranial series from town of Baturyn found during excavations by V. Kovalenko, O. Kovalenko, Yu. Sytyi, V. Mezentsev, V. Skorokhod during 2005–2015 on the territory of the Fortress (the Cathedral of the Life-Giving Trinity) and in resedimentation. Computer software designed by B. Kozintsev and O. Kozintsev in 1991 has been applied in the research. 14 craniometric traits defined by R. Martin have been involved into the analysis.
The objective of this paper is to introduce a new material into scientific domain and define the place of the cranial series among famous anthropological types. To achieve this goal, it is necessary to provide the general morphological description of female group from Baturyn of the 17th – 18th cent. on the background of neighbouring ethnic groups from Ukraine and Eastern Europe (synchronistic and diachronic methods), determine the distance between separate cranial series of the 14th – 19th cent. with the help of multidimensional canonical and cluster analysis, and to find out the place of female population from Baturyn in the system of craniological types of Eastern Europe.
For the first time, the general female series from Baturyn of the 17th – 18th cent. including 33 skulls has been created. After comparison of square divergence of 69 basic traits and indexes of Baturyn female skulls with the standard ones, one can conclude that the researched selection is heterogeneous by its structure. The multidimensional canonical and cluster comparative analyses of the studied female group of the 17th – 18th cent. with the synchronic and earlier series from the 14th – 19th cent. from Eastern Europe (except the Caucasus) have demonstrated its closest similarity to the urban skulls from Podillia.
The comparison of 37 studied groups of the 14th – 19th cent. with the method of multidimensional canonical analysis in three-dimensional space has demonstrated the connection of the female skull sample from the town of Baturyn with two urban groups from Podillia.

ESD-based self-learning tools are currently not widely available in elementary schools. The purpose of this study is to find out the existence of ESD-based virtual field trip learning media that can be used independently by students in elementary school. This study uses a descriptive qualitative approach. The data collection technique was through a preliminary study with interviews with several elementary school teachers, observations, questionnaires, and literature studies. Based on the data obtained most of the implementation of ESD learning in elementary schools has not been carried out optimally and not many teachers in elementary schools use applications that contain virtual field trip videos in the learning process, especially on natural resource conservation materials. Based on observations on the Google Play Store, there are not many Android applications as independent learning media for students in ESD-based elementary schools, especially on the topic of natural resource conservation (hydroponics). This research implies that it can be a source of data from the availability of independent learning media for elementary school students today.

Immunopathogenesis of Silicotuberculosis: A Literature Review
Authors: Esha Indi , Simatupang Elvando Tunggul Mauliate 
Published: November 2023

Silicotuberculosis is a tuberculosis infection that emerges as a silicosis complication. A silicosis patient is 2.8 to 39 times more likely to develop pulmonary tuberculosis (TB). Moreover, the fibrotic condition caused by silicosis may exacerbate the symptoms and worsen the clinical outcome of silicotuberculosis patients. The current report suggests that the immune system plays an important role in the pathogenesis of this disease. Silicosis or silica exposure might interfere with the immunological response, especially the macrophages, which permit the Mycobacterium tuberculosis to infect the host. In this literature review, we will discuss the definition, epidemiology, and immunopathogenesis of silicotuberculosis.
Information Disorders and Civil Unrest
Authors: Petla Vhonani 
Published: November 2023

Various scholars in the global north have explored information disorders and have been able to present findings on them and their implications on various sectors; unfortunately, this has not always been the case for the global South. This desktop study explores information disorders in South Africa during the July 2021 unrest in Gauteng and KwaZulu Natal between the 7-19 July. This paper demonstrates that information disorders on social media have been used as a catalyst for unrest; they are used to mobilize both those online and offline. This work shows how politicians and influential individuals used these disorders to facilitate and instigate civil unrest during July 2021. This work argues that people in political office and influential individuals should be aware of the responsibility of being influential and the consequences of their social media posts. The work further argues that despite various ways to counter these information disorders, the digital divide and literacy rate in South Africa make this challenging.

Extended Habitability of Exoplanets Due to Subglacial Water
Authors: Wandel Amri 
Published: November 2023

Abstract
Considering subglacial liquid water, a significant extension of the classical Habitable Zone is obtained. Elaborating on the model of Wandel it is shown how an atmosphere and liquid water could survive on tidally locked planets closely orbiting an M-dwarf host, extending the Habitable Zone boundary inwards. In addition, subglacial liquid water could extend the Habitable Zone beyond the outer boundary of the conservative Habitable Zone as well. These two results enhance the circumstellar region with a potential for liquid water well beyond the conservative boundaries of the classical Habitable Zone. It is argued that the probable recent JWST detection of atmospheric water vapor on the rocky Earth-sized exoplanet GJ 486 b, along with earlier detections of water on other planets orbiting M-dwarf stars, gives an empirical answer to the much-argued question of whether such planets can support liquid water, organic chemistry, and eventually life. It is shown how water on terrestrial planets closely orbiting M-dwarf stars may sustain in a subglacial melting layer. Finally, the model is applied to a few exoplanets demonstrating how water detection may constrain their atmospheric properties.
