Background and Study Aim. Understanding the physical condition parameters of students during physical education classes is essential in the context of modern education. This understanding contributes to the development of effective teaching strategies tailored to the specific needs of this demographic. The aim of the study is to investigate the structure and interrelations of physical condition (PC) parameters of students aged 17-19 years in the process of physical education classes.
Material and Methods. The study involved 153 students aged 17-19 years old, and their physical development, functional, and physical fitness indices were recorded. The study analyzed intra- and intergroup correlations among 55 physical condition (PC) indices. It examined the correlations among integral components of students' structure, including somatic health (SH), adaptation potential (AP), aerobic physical work capacity (APWC), and biological age (BA). The study utilized factor analysis, correlation analysis, dispersion analysis, and regression analysis to examine the relationships and patterns within the collected data.
Results. The analysis of intra- and intergroup relationships among the studied parameters revealed that the structure of physical condition (PC) is consistent between girls and boys. There are close linear dependencies, similarities, and differences in the interrelations of integral PC parameters, including somatic health (SH), adaptation potential (AP), aerobic physical work capacity (APWC), and biological age (BA), between boys and girls. The regression model coefficients indicate that for both genders, SH is influenced by APWC and AP. In girls, AP is dependent on SH and BA, while in boys, AP depends on SH, BA, and APWC.
A strong relationship between APWC and resting heart rate (HR) was identified during testing, with boys demonstrating higher levels of APWC at lower initial HR values compared to girls.
Conclusions. The study has provided valuable insights into the key components of the physical condition (PC) structure among 1st-year students. These components encompass physical development, adaptation potential, health, cardiorespiratory system functional capacities, speed-strength fitness, biological age, and degree of aging. Findings emphasize the significance of resting bradycardia as an informative marker and criterion for assessing APWC during moderate-intensity muscle activity. The developed mathematical models have proven effective in modeling and predicting students' PC, including the individual integral components (SH, AP, APWC, and BA). These models provide valuable tools for anticipating potential changes in these parameters.

Authors: Bozkurt Sinan 
Published: October 2023

Background and Study Aim. Understanding and addressing potential variations in hand dexterity among children is essential for educational strategies and interventions aimed at enhancing fine motor skills development in this age group. The study's objective was to assess hand dexterity levels among 11-12 years old secondary school students, considering variables such as gender, grade, and hand preference.
Material and Methods. Ninety-three students (41 females and 52 males) in grades 5 and 6 of the secondary school. The Grooved Pegboard Test (Lafayette Model 32025) was used as a data collection tool to determine the students' performance in hand dexterity (fine motor skills). The Mann-Whitney U-test was used to test for differences between gender, grade, and hand preference in the mean GPT scores.
Results. Results showed that both female and male 6th graders had better GPT performance in both dominant and non-dominant hands than 5th graders. On the other hand, there were no significant grade differences in GPT performance between dominant and non-dominant hands (p>0.05). There was no difference in GPT performance between 5th and 6th grade (p>0.05). There were no statistical differences between females and males in GPT performance in either the dominant or non-dominant hand (p>0.05).
Conclusions. Results highlight the importance of considering age-related changes in fine motor skills when developing educational strategies and interventions for children in the 11-12 year age group. Further research may be needed to explore the underlying factors contributing to these variations in hand dexterity.

Study purpose. Three-Cone Drill using the Ball (TCDB) High-Intensity Interval Training (HIIT) is an exercise that requires players to perform fast movements and sharp changes of direction using a ball over three cones with high intensity. This exercise is based on the application of specific training principles using the ball and the principle of overload, which aims to improve agility and dribbling skills. This study aimed to evaluate the effect of TCDB+HIIT on the agility and dribbling ability of student futsal athletes.
Materials and methods. This study used an experimental method with a One-Group Pretest-Posttest Design. The participants in this study were student futsal athletes, totaling 14 players aged 16.6±0.7 years, with body height 170.2±3.36 cm, body mass of 59±9.11 kg, and BMI 20.4±3.25. The research instruments used were the Illinois Agility Test and the futsal dribbling test. Data analysis used the Paired Samples T-Test at a significance level of 0.05; the prerequisite test used was the Shapiro-Wilk test.
Results. Based on the results of the Paired Samples T-Test test, it was found that the sig value (2-tailed) of the speed variable was 0.001 < 0.05, with an increase of 0.99 ± 0.57. In the dribbling variable, the sig (2-tailed) value is 0.001 < 0.05, with an increase of 1.88 ± 1.722.
Conclusions. This study concludes that TCDB + HIIT exercises are effectively applied to increase futsal players’ agility and dribbling abilities.

Background. Intraductal papilloma (IDP) is not usually considered as an obligate precancerous lesion since the cases of its progression into cancer are exceedingly rare.Aim. To analyze the impact of IDP on the risk of breast cancer in the future.Materials and methods. This retrospective study included patients aged 22–82 years operated on for IDP (n = 304) and other benign breast tumors (n = 304) between 2014 and 2022. We checked these patients in the cancer registry of Primorsky Regional Oncology Dispensary to find out whether any of them developed any type of cancer, including breast cancer. Then we calculated the odds of developing breast cancer in both groups.Results and conclusion. We found that paients with a history of IDP are 2.4 times more likely to develop breast cancer. The incidence of other cancer types did not differ significantly between the two groups. Our findings are consistent with the results of similar foreign studies and might indicate that IDP and breast cancer share the same etiological factor. They can also highlight specific characteristics of asymptomatic IDP.

Background. Individual molecular characteristics of a tumor can serve as a basis for a tailored approach to therapy, prediction of the disease course and outcome, and timely treatment correction in cancer patients. Tumor genomic profiling allows for a more precise tumor assessment in an individual manner. Accurate identification of the HER2 status of a breast tumor is crucial for clinical decisions and appropriate treatment strategy.Aim. To increase the efficacy of systemic therapy for breast cancer, reduce inappropriate prescribing, and ensure a tailored approach to systemic breast cancer therapy using the information on individual molecular characteristics of the tumor.Materials and methods. We explored the expression of 100 genes involved in breast cancer development in 106 tumor samples from patients with metastatic breast cancer. We used the nCounter technology based on direct digital target detection using color-coded molecular barcodes. We analyzed the expression of 28 genes with a high predictive value for breast cancer.Results. The nCounter technology allowed us to perform semiquantitative assessment of the expression of 28 genes in tumor tissue samples. We compared the expression of ERBB2 and HER2. The HER2 expression between 252.32 and 6000 barcodes was equivalent to HER2 (0) status; between 6000 and 9196.25 barcodes, to HER2 (1+); between 9196.25 and 15022.46, to HER2 (2+/ISH±); and 15022.46 barcodes, to HER2 (3+). In case of HER2 (3+) and ERBB2 below 6000 barcodes, the result was considered false positive. In case of HER2 (0) or (1+) and ERBB2 above 15 000 barcodes, the result was considered false negative. In 18 tumors, the discrepancies in the results meant two principally different breast cancer subtypes requiring different treatments; in 2 cases, the discrepancies were in the level of HER2 expression.Conclusion. HER2 testing should be performed on an excision sample (ideally on the same block that was used for genomic testing). Despite the correlation between the HER2-enriched molecular class and the response to anti-HER2 therapy, the final result on HER2 status in discordant cases should be based on currently approved assays after results validation.

Breast cancer (BC) occupies the second place in terms of incidence and the first ranking place in terms of mortality among oncopathology in women. The article presents the current state of the problem of the combination of BC and pregnancy, the impact of pregnancy on the course and outcome of breast oncopathology, as well as modern hypotheses for the development of breast cancer during pregnancy. It is shown that the current studies are quite contradictory and in many ways not accurate enough in methodology and materials. We present a clinical case of BC associated with pregnancy. The case is interesting from 2 positions: on the one hand, the patient’s tumor process is associated with pregnancy, on the other hand, there is a very rare combination of HER2/neu- and BRCA1-positive status.According to the presented literature data and our own data, it was concluded that the treatment of patients with BC during pregnancy is a difficult task and is often accompanied by tumor progression, despite the standard treatment regimens. Undoubtedly, this group of patients needs to develop new methodological approaches to antitumor treatment based on a deep analysis of the molecular genetic characteristics of the tumor, the hormonal background in general, and its effect on the tumor process during pregnancy. Such a personalized approach will improve the results of treatment of young patients with BC during pregnancy.

Published: October 2023

Abstract
We aim to compute macroseismic parameters (location and magnitude) using the BOXER code for the first time on the citizen testimonies, that is, individual intensity data points (IDPs) at the global scale collected and made available by the LastQuake system of the European–Mediterranean Seismological Centre (EMSC). IDPs available for different earthquakes are selected to eliminate those that are geographically inconsistent with most data; then they are clustered spatially based on various methods. For each cluster with at least three IDPs, a macroseismic data point (MDP), corresponding to an intensity value assessed for given localities as in classical macroseismic studies, is computed by various central tendency estimators (average, median, and trimmed averages). Finally, macroseismic parameters are obtained by MDP distribution using two location methods of BOXER code. For each earthquake, we used raw and corrected intensities and 132 different combinations of grouping methods, estimators, and BOXER methods. We assigned a ranking to the combinations that best reproduce instrumental parameters and used such a ranking to select preferred combinations for each earthquake. We analyzed retrospectively the reliability of the parameters as a function of time and space. The results are essentially identical using original and corrected intensities and show higher reliability for BOXER’s method 1 than for method 0; they are dependent on the geographical area, and generally improve over time and with the number of IDPs collected. These findings are useful for the future real-time analyses, and for evaluating the location and magnitude of earthquakes whenever a sufficient number of IDPs are available and with a distribution such that MDPs can be derived and the BOXER method applied.

Published: October 2023

Background: Adjuvants are added to intraperitoneal local anesthetics to prolong analgesia however no study compares Dexmedetomiditine with Ketamine as adjuvant to Ropivacaine for laparoscopic cholecystectomy.
To compare efficacy of intraperitoneal instillation of Ropivacine with Dexmedetomidine versus Ropivacaine with Ketamine for postoperative pain relief following laparoscopic cholecystectomy.
Methods: Sixty patients ASA I and ASA II undergoing laparoscopic cholecystectomy were randomly allocated in three groups and received Ropivacaine 0.2 % (group R), Ropivacaine 0.2 % alongwith Dexmedetomidine 0.7 micogrms/ kg (group RD) and Ropivacaine with Ketamine 0.5 mg/kg (group RK) to a total volume of 40ml.The primary outcome measured was time to request of rescue analgesia while secondary outcomes were post op numeric rating scale, total dose of rescue analgesia required in 24 hours and haemodynamic parameters in postoperative period.
Results: The median time to request of rescue analgesia was shortest in R group 55 [42.5-70] minutes followed by RK group 60 [50.50-72.50] and maximum in the group RD the time being 900 [86.25 -1440] minutes while haemodynamics remained stable in all the groups. Similar findings were seen for total demand of analgesia in 24 hours as well as NRS scale both static and dynamic which was measured periodically in the first 24 hours.
Conclusion: Dexmedetomiditine 0.7 micrograms per kg when used as adjuvant with Ropivacine is effective combination that prolongs duration than Ropivacaine alone or when used with Ketamine 0.5 mg per kg body weight however total dose of rescue analgesia was significantly less in Ketamine group compared to Ropivacine alone and least when Dexmedetomiditine is used as adjuvant.

Authors: Ndou Adam 
Published: October 2023

The moderating effect of parental income on parental financial communication and financial literacy is increasingly becoming important. The objective of this study was to determine whether the relationship between parental financial communication of young adults and their financial literacy is moderated by parental income. Financial literacy was measured through financial knowledge, financial behaviour, financial attitudes, and financial decision-making. Quantitative research approach was adopted for this study. Self-administered questionnaire was used to collect data among young adults in South Africa. Moderated regression analysis was used to analyse data. Four hypotheses were tested. The results showed that parental income moderated the relationship between parental financial communication with financial knowledge, financial behaviour, financial attitude, and financial decision-making. Therefore, the overall results indicated that the relationship between parental financial communication and financial literacy is moderated by parental income. This study is amongst the first to investigate whether the relationship between parental financial communication and financial literacy is moderated by parental income. This study concluded by providing recommendations and suggestions for future research.

Published: October 2023

Continuing Professional Teacher Development (CPTD) refers to the ongoing learning and development of teachers throughout their careers. It involves a range of activities, programs, and initiatives designed to help teachers improve their knowledge, skills, and effectiveness in the classroom. CPTD programs can take many different forms, such as workshops, seminars, mentoring programs, online courses, and peer networks. This desktop review paper examines the role of CPTD on teachers' and learners’ achievement. The paper reviews among others the following; the nature and concept of CPTD, the importance of CPTD, South African teacher education policy framework and CPTD, the educational achievement and CPTD, school effectiveness and CPTD, learner and teacher learning and CPTD. The paper uses social learning theory as a theory that underpins the paper and makes some plausible recommendations.
TAPHONOMY OF TINY TETRAPOD TRACKS IN AN EXAMPLE FROM THE LOWER PERMIAN (CISURALIAN) SŁUPIEC FORMATION (SW POLAND)
Authors: SADLOK GRZEGORZ 
Published: October 2023

Abstract
The continental Lower Permian Słupiec Formation (the Sudetes Mountains, southwestern Poland) is well known for the occurrence of fossilized tracks of Early Permian tetrapods. Previous reports have focused on the taxonomy of tracks and their producers. The track assemblage was apparently missing the footprints of amphibians and thus such tetrapods were thought to be truly absent in the Słupiec Early Permian paleohabitat. The present paper utilizes the results of experiments and field surveys in order to test a possibility that tracks of tiny tetrapods (e.g., with body mass &lt; 9 g), including amphibians, could be missing due to taphonomic filtration. The experimental tests were performed to investigate the following: (1) the interplay between the sizes of the penetrator (representation of trackmaker’s pes and manus) and the particles within the substrate, with emphasis on how the size interplay affects the lamina-modification mechanism, e.g., lamina-piercing by sand versus lamina compaction/displacement by sand or clay; (2) undertrack production in laminated sandy substrates by tiny tetrapods; and (3) the taphonomic impact that biofilm may have on the occurrence of tiny tetrapod tracks in clay. The results of experimental tests and the field survey suggest that tiny tetrapod tracks (e.g., amphibians) may be underrepresented in the Słupiec Formation track assemblage due to negative taphonomic filtration.
Geochemical Composition Variations and Tectonic Implications of the Baoligaomiao Formation Volcanic Rocks from the Uliastai Continental Margin, Southeast Central Asian Orogenic Belt
Authors: Tang Jianzhou , Zhang Zhicheng , Ji Zejia 
Published: October 2023

Abstract
The Permo-Carboniferous tectonic evolution in the Uliastai continental margin (UCM), north of the southeast central Asian Orogenic Belt, remains controversial. This work examined the geochemical composition of the felsic volcanic rocks from the lower and upper part of the Baoligaomiao Formation in the UCM. Zircon U-Pb ages reveal that the Baoligaomiao Formation has a long-lived eruption duration, from ca. 285 to 328 Ma. The lower part (ca. 328–310 Ma) of the Baoligaomiao Formation is dominated by clastic and pyroclastic rocks with subordinate intermediate-felsic volcanic rocks, whereas the upper part (ca. 307–285 Ma) mainly consists of felsic volcanic rocks and pyroclastic rocks. Calculations reveal that the felsic volcanic rocks from the lower part have low zircon saturation temperatures (TZr = 747℃–795℃), whereas those from the upper part exhibit high TZr (ca. 793℃–930℃). Zircons from the lower part exhibit high εHf(t) values and 176Lu/177Hf ratios, in contrast to the low εHf(t) values and 176Lu/177Hf ratios of zircons from the upper part. Those petrogeological and geochemical shifts might support the tectonic switch model in the UCM at the end of the Carboniferous, providing new constraints on the Late Carboniferous closure of the Hegenshan Ocean.
