Objectives:
Artefacts from dental implants in three-dimensional (3D) imaging may lead to incorrect representation of anatomical dimensions and impede virtual planning in navigated implantology. The aim of this study was quantitative assessment of artefacts in 3D STL models from cone beam CT (CBCT) and multislice CT (MSCT) using different scanning protocols and titanium-zirconium (Ti-Zr) and zirconium (ZrO2) implant materials.

Methods:
Three ZrO2 and three Ti-Zr implants were respectively placed in the mandibles of two fresh human specimens. Before (baseline) and after implant placement, 3D digital imaging scans were performed (10 repetitions per timepoint: voxel size 0.2 mm³ and 0.3 mm³ for CBCT; 80 and 140 kV in MSCT). DICOM data were converted into 3D STL models and evaluated in computer-aided design software. After precise merging of the baseline and post-op models, the surface deviation was calculated, representing the extent of artefacts in the 3D models.

Results:
Compared with baseline, ZrO2 emitted 36.5–37.3% (±0.6–0.8) artefacts in the CBCT and 39.2–50.2% (±0.5–1.2) in the MSCT models. Ti-Zr implants produced 4.1–7.1% (±0.3–3.0) artefacts in CBCT and 5.4–15.7% (±0.5–1.3) in MSCT. Significantly more artefacts were found in the MSCT vs CBCT models for both implant materials (p &lt; 0.05). Significantly fewer artefacts were visible in the 3D models from scans with higher kilovolts in MSCT and smaller voxel size in CBCT.

Conclusions:
Among the four applied protocols, the lowest artefact proportion of ZrO2 and Ti-Zr implants in STL models was observed with CBCT and the 0.3 mm³ voxel size.

Introduction: In recent years, there have been more and more concerns about whether wearing mobile phones near the reproductive organs, including the testicles, may cause significant health consequences, such as sperm dysfunction, decreased semen production, impaired testicular morphology, and thus become the cause of male infertility. Determining the relationship between the electromagnetic radiation of mobile phones and infertility in men may in the future reduce the male factor in the problem of infertility of couples and thus improve the quality of life.
Aim of the study: The aim of this review is to attempt to assess the impact of radiofrequency electromagnetic radiation emitted from mobile phones on male reproductive organs in the context of male fertility disorders.
Materials and methods: The work was created based on the PubMed database. Articles were searched in English using the following keywords: mobile phone, testes, male infertility, electromagnetic radiation.
Description of the state of knowledge: Changes in semen parameters, including reduced motility and changes in sperm morphology, have been reported in animal studies. Features of damage to living cells under the influence of oxidative stress generated by GSM radiation were also observed. Similar phenomena have been reported in vitro in human semen samples and in clinical trials in men.
Summary: There are not enough studies providing strong evidence for the direct negative effect of mobile phones on male fertility. It is necessary to conduct more research in order to eliminate other factors that could potentially change the results of the analyses, as well as to standardize the test methods and the test variables.
Perceptions and experiences of allied health professionals of fabric orthoses for people with joint hypermobility syndromes: a qualitative study
Authors: Snowdon Nicky , Dadla Sakina 
Published: August 2023

Background/Aims Hypermobility spectrum disorders and hypermobile Ehlers–Danlos syndrome are multisystem, connective tissue disorders, associated with problems such as joint hyperextensibility, tissue fragility, poor proprioception and pain. Fabric orthoses might improve proprioception and assist with joint protection. No previous research has investigated this possibility. This study aimed to explore the perceptions and experiences of experts with experience of fabric orthoses who have used fabric orthoses with individuals with hypermobility spectrum disorders and hypermobile Ehlers–Danlos syndrome. Methods A total of six experts in fabric orthoses and hypermobility spectrum disorders/hypermobile Ehlers–Danlos syndrome participated in semi-structured interviews. A thematic analysis was undertaken by two analysers. Themes were validated with a member checking exercise involving three of the original participants. Results Three themes were identified. The first theme, ‘it is immediate’, described the reported positive effects when the orthosis is first donned. The second theme described a proposed mechanism of effect in which improved proprioception and realignment work together to support improved joint stability. The third theme, ‘tips for success’, captured ways in which effectiveness and acceptability are maximised, with importance ascribed to collaborative assessment. Conclusions Fabric orthoses have the potential to be effective in people with hypermobile Ehlers–Danlos syndrome or hypermobility spectrum disorders. This study is to inform futher research into the use of fabric orthoses. Further research could prioritise short-term effect, using mixed methods to explore users’ experiences alongside measures of pain, joint stability and function. Crossover studies could compare custom-made orthoses vs off-the-shelf, or orthoses with directional support vs compression alone. If short-term studies support effectiveness and acceptability, longer-term studies could include the role of fabric orthoses in prevention of disability.

Published: August 2023

Abstract
This commentary highlights pervasive challenges related to the science of intellectual and developmental disabilities (IDD), which we often take for granted. We argue that social power asymmetry and entrenched patterns of epistemic injustices undermine our science and call attention to the need to maximize our efforts to undo these unfair practices to enhance future care and research in IDD.
Optical trapping based on microring resonators with a transverse slot structure
Authors: Li Zheng , Cheng Yi , Liu Jin , Peng Guanju 
Published: August 2023

Over the past few decades, optical manipulation has emerged as a highly successful tool in various fields such as biology, micro/nanorobotics, and physics. Among the different techniques, the transverse slot optical waveguide has shown remarkable potential in enhancing the field and significantly improving optical trapping capabilities. Additionally, microring resonators have demonstrated the ability to enhance the field at specific resonance wavelengths, enabling the manipulation and capture of particles. In this study, we investigated the impact of the structure on nanoparticle capture by introducing a 50 nm transverse slot in a 5 µm microring resonator. Through the integration of a transverse slot in the microring resonator, we observed a substantial increase in the maximum bound optical power for a nanosphere with a refractive index of 1.6 and a diameter of 50 nm, reaching 3988.8 pN/W. This value is 2292 times higher than the maximum optical force in a straight waveguide and 2.266 times higher than the maximum optical force in a microring resonator. The proposed structure significantly enhances the optical trapping capabilities for nanoscale particles, thus paving the way for the development of advanced micro/nanomanipulation techniques.

ABSTRACT The aim of this paper is to examine the relationship between the quality of family functioning and academic achievement in adolescents, as well as to evaluate their extent as related to gender and age. The sample consisted of secondary school students aged 14 to 19 (N = 584) from six secondary schools in Vojvodina, Serbia. Data was collected using the Family Adaptability and Cohesion Evaluation Scale (Olson et al., 1985) and the Questionnaire on Socio-Demographic Characteristics (Erdeš-Kavečan et al., 2010). Descriptive statistical methods, t-test for Independent Samples, two-way ANOVA and Linear Regression Analysis were used for data processing. The results obtained in this research paper indicate that the level of cohesion and the level of adaptability within the family are significant predictors of school success in adolescents. Concerning the respondents' gender, there were statistically significant differences in the evaluation of both dimensions of family functioning observed (i.e. cohesion, adaptability), as well as in the academic achievement in adolescents.Key words: academic achievement, school success, quality of family functioning -----SAŽETAK Cilj je rada ispitati odnos između kvalitete funkcioniranja obitelji i akademskog postignuća adolescenata, kao i procijeniti njihov uspjeh s obzirom na spol i dob.

Comic Strip Humour and Empathy as Methodological Instruments in Teaching / HUMOR I EMPATIJA STRIPA KAO METODOLOŠKI INSTRUMENTARIJ U POUČAVANJU
Authors: Lazzarich Marinko 
Published: August 2023

AbstractLaughter is an instinctive activity that facilitates social communication and can be used to enrich the education system. Taking into consideration that children are, by their nature, visually oriented, the humour and empathy of the comic strip make it an appropriate methodological instrument for the acquisition of new learning materials. The popular comic strip Alan Ford consolidates realist elements with social satire and black humour, owing its popularity and longevity to the creativity of its authors who accept self-irony as a powerful tool in their artistic expression. The author of this paper examines the possibility of applying the Alan Ford comic strip in primary and secondary school teaching as well as the influence of humorous discourse on the efficiency of the educational process. The importance of humour, as one of the most desired teacher’s characteristics, is examined in the research. A total of 14 schools of the Primorsko-Goranska County participated in the research; the sample consisted of 315 primary school pupils and senior secondary school students. Data distribution analysis points at the conclusion that humour has a significant influence on the efficiency of teaching and the quality of relationships between teachers and pupils, while the methodology of comic strips provides everyday discourse in teaching. Key words: Alan Ford; comic self-irony; humour in class; media culture. --- Smijeh je instinktivna aktivnost koja osim što olakšava društvenu komunikaciju, može oplemeniti i pedagoški sustav. Budući da su djeca po prirodi usmjerena vizualnoj percepciji, humor i empatija stripa pogodni su metodološki instrumentarij za usvajanje novih obrazovnih sadržaja. Strip Alan Ford objedinjuje realističke elemente sa socijalnom satirom i crnim humorom, a svoju popularnost i dugovječnost zahvaljuje kreativnosti svojih autora koji su samoironiju prihvatili kao moćno sredstvo slikovnog izričaja. Autor istražuje utjecaj humornoga diskursa na učinkovitost odgojno-obrazovnoga procesa te mogućnosti primjene Alan Forda u osnovnoškolskoj i srednjoškolskoj nastavnoj praksi. U sklopu istraživanja ispitana je važnost humora kao jedne od poželjnih osobina nastavnika. Istraživanje je provedeno u 14 škola Primorsko-goranske županije, na uzorku od 354 učenika osmih razreda osnovnih i završnih razreda srednjih strukovnih škola i gimnazija. Iz analize distribucije rezultata može se zaključiti kako humor bitno utječe na učinkovitost poučavanja i na kvalitetu odnosa između nastavnika i učenika, dok metodika stripa u nastavi osigurava diskurs svakodnevnice.Ključne riječi: Alan Ford; humor u nastavi; medijska kultura; samoironija; strip.

Published: August 2023

AbstractThe paper presents the results of the investigation of gender differences in motor abilities of preschool boys (n=106) and girls (n=121), 6-7 years of age. Eighteen composite motor tests adapted for preschool children, three for each hypothetical latent motor dimension (coordination, flexibility, strength, agility, accuracy and balance) were used to measure motor performance of the subjects. Statistically significant gender differences in motor variables were established. In the majority of variables better results were achieved by boys, except for the variable assessing flexibility – straddle seated forward bend, in which girls performed better. The results showed that this set of variables had a relatively high discriminant power. The measures influenced by the motion regulation mechanism had the greatest contribution to the discriminant function. The results indicate occurrence of sexual dimorphism in children’s motor abilities even at the age of six and half years. Key words: preschool age; sexual differences; sexual dimorphism *****SažetakU radu su ispitane moguće razlike po spolu u motoričkim obilježjima dječaka (n=106) i djevojčica (n=121) predškolske dobi, starosti od 6 do 7 godina. U istraživanju je korištena baterija od osamnaest modificiranih testova za uzrast predškolske dobi, od kojih su za svaku latentnu dimenziju motoričkih sposobnosti bila predviđena po tri testa (koordinacija, fleksibilnost, snaga, agilnost, preciznost, ravnoteža). Utvrđene su značajne razlike po spolu između dječaka i djevojčica u mjerenim varijablama motoričkih sposobnosti. U većini varijabla bolje rezultate postizali su dječaci, osim u jednoj varijabli iz skupine procjene fleksibilnosti – pretklon u sjedu, u čemu su djevojčice bile bolje. Rezultati diskriminacijske analize potvrdili su kako taj skup manifestnih varijabli za procjenu motoričkih sposobnosti dobro razlikuje dječake i djevojčice. Najveći doprinos mogućem razlikovanju djece s obzirom na spolnu pripadnost pokazale su one varijable koje su pod utjecajem mehanizma za regulaciju kretanja. Rezultati ukazuju na to kako je već kod djece od šest i pol godina došlo do pojave spolnog dimorfizma u motoričkim sposobnostima. Ključne riječi: predškolska djeca; spolni dimorfizam; spolne razlike

AbstractWe can perceive environmental education also as an education for a nicer and better life. We know for the latter one that we will have to change it drastically if we want to preserve our planet for future generations. In this article we firstly introduce the concept of environmental education and stress the importance of environmental literacy. Secondly, we present the results of the research that has been carried out on a sample of 56 teachers of the first triad and their 823 pupils. We identify the presence of environmental education in the process of planning annual school action plans, of performing environmental education and the willingness of younger pupils to cohabitate with nature. Finally, our results show that the more the teachers plan their environmental activities, the more they perform them. The more they perform positive environmental activities, the more pupils are environmentally active in their own free time. Key words: cohabitating with nature; environmental education; first school triad; process of planning; process of performing. ---SažetakObrazovanje za okoliš možemo poimati kao obrazovanje za ljepši i bolji život.

Nadalje, predstavit ćemo rezultate istraživanja koje je provedeno na uzorku od 56 nastavnika u prvoj trijadi s ukupno 823 učenika. Identificirali smo prisutnost obrazovanja za okoliš u procesu godišnjeg akcijskog planiranja škola, realizacije obrazovanja za okoliš i spremnost mlađih učenika da kohabitiraju s prirodom. Napokon, naši rezultati ukazuju na to da što učestalije nastavnici planiraju aktivnosti vezane uz okoliš, da ih više i izvode. Kod brojnijeg izvođenja aktivnosti u okolišu, učenici postaju svjesni okoliša i u slobodno vrijeme.

Background and Study Aim. Understanding and assessing functional asymmetry among athletes is pivotal, as it has the potential to reveal hidden strengths and weaknesses that can profoundly influence competitive performance. Study Aim: to perform a comparative analysis of functional asymmetry indicators among athletes in cyclic sports (short track), martial arts (karate, taekwondo), and esports (CS:GO).
Material and Methods. The study involved athletes of martial arts (n=10, age 18.9±0.12, experienced athletes), elite players of semi-professional CS:GO teams (n=10, age 19.2±0.50), and short track athletes (n=10, age 19±0.09, experienced athletes). The functional asymmetry was determined using a specialized program for iOS tablets.
Results. Esports athletes a higher number of taps during the test within a given unit of time. They also exhibit shorter reaction times and have briefer tap durations using both their right and left hands, in comparison to athletes specializing in other disciplines. Across all three specializations, athletes display minimal disparities between their right and left hands regarding tap count, reaction time, and tap duration at each of the six test stages. The variance in tap count ranges from 0 to 1.40 times, while reaction time differs by 0 to 2.33 milliseconds, and tap duration varies between 1.53 to 8.69 milliseconds.
Conclusions. The exploration of motor functional asymmetry holds significant importance in analyzing the motor skills and perceptual-motor capabilities of athletes across diverse sports and proficiency levels. A comparison of functional asymmetry metrics among athletes from three distinct specializations affirmed the similarity in outcomes across all measures. This suggests that elite athletes possess a heightened level of movement coordination and symmetry in their execution between their right and left hands. The advanced level of sports training contributes to the balanced enhancement of intermuscular coordination, further positively impacting visual-motor reaction times.
Water Gymnastics as a Therapeutic Method to Improve Motor Planning in Children with Intellectual Disability
Authors: Georgieva Diyana , Ivanova Veselina 
Published: August 2023

Study purpose. This paper is devoted to an experimental study aimed to identify the effects of water gymnastics as a therapeutic method for improving motor planning in children with intellectual disability studying in general and special education institutions.
Materials and methods. Twenty-three children (13 boys and 10 girls) aged from 6 to 11 years (x̅ = 8.61) participated in the study. Three neuropsychological tests were used to study motor function: Sequential alternation of fist-palm-side, Graphic test “Fence”, and Fist-palm. Data were collected before and after participation in an 11-month therapy course conducted in a water environment. Descriptive analysis and One-way analysis of variance (ANOVA) were applied to process the empirical material. Cohen's η was used to interpret the effect size attributed to the therapeutic intervention.
Results. Programming, regulation, and control, as the main components of motor planning, showed improvement after the children participated in the organized sessions, as evidenced by the large or larger than typical effect size η=[0.37:0.45+] recorded and the nonsignificant differences between groups differentiated by level of intellectual disability, age, and gender at the control measurement stage (p > 0.05).
Conclusions. The results lead to the generalization that at the final stage of the study, all three factors (level of intellectual disability, age and gender) had no significant influence on the development of motor planning, confirming the effects of water gymnastics as a technology for its improvement.

Abstract
The 2022 eruption of Mauna Loa Volcano, Hawai’i, was accompanied by continuous seismic tremor that began about 30 min before and ended several days after the eruption. We characterize the amplitude history and frequency content of the tremor, and we use a network covariance-based method to estimate its source location. The tremor exhibits multiple narrow spectral peaks between 1 and 3 Hz, and its amplitude varies through time in a spasmodic manner. Our location results track a northeast migration of shallow sources through the summit region in the first few hours of the eruption. For the remainder of the eruption, source locations cluster in the vicinity of the erupting vent in the northeast rift zone. We attribute the tremor source to gas dynamics in the upper reaches of a basaltic dike. However, limitations in instrumentation and knowledge of the subsurface velocity structure may preclude an assessment of the source mechanism. Our results illustrate the value of characterizing and locating tremor for tracking magma movement, and demonstrate a use for dense and calibrated seismic instrumentation on active volcanoes. The location method we use requires substantial parameter testing, reflecting the potential benefit of developing more flexible approaches toward real-time automated assessment of tremor at volcanoes.
