Authors: Yari Fatemeh , Rafiei Mehdi , Golestaneh Arash , Ehrami Eilnaz
Published: July 2022

Introduction: Orthognathic surgery not only changes the appearance of the face and the occlusion, but also changes the biomechanics and force of chewing. The aim of this study was to evaluate the maximum changes in byte force after orthognathic surgery in class III patients.
Materials & Methods: In this clinical trial study, 20 class Ш skeletal patients referred to the School of Dentistry of Isfahan Azad University in the academic year 97-98 were selected and were divided into two groups before orthognathic surgery and 3 months after orthognathic surgery. The surgical technique in these patients was 2-jaw technique (Lefort 1 and BSSO). The area of the first right maxillary molar and the left maxillary first molar were measured at two intervals before surgery and three months after surgery. The sensor was first placed on one side of the first maxillary molar, then on the other side, and vice versa. The measurements were repeated three times on each side and the highest number was recorded as the patient's MBF (Maximum bite force). Data were analyzed using ANOVA and Tukey statistical tests (α = 0.05).
Results: Mean maximum dental bite force was significantly decreased 3 months after surgery (p value < 0.001); this did not lead to a significant difference between maximum bite force and gender (p value = 0.244).
Conclusion: Maxillofacial surgery in class III skeletal patients reduces the byte force in 3 months after maxillofacial surgery.

Published: July 2022

Introduction: Marginal adaptation is one of the key factors in the success of dental crowns. It is necessary to identify marginal adaptation in order to determine the spacing and prevent the onset of diseases. This study sought to use 3D and manual printing methods aiming at manufacturing heat press full-coverage extra-coronal restorations with more marginal adaptation.
Materials & Methods: This study was conducted in the year 1397-98 at the Islamic Azad University of Isfahan using descriptive-analytical and cross-sectional method with 20 samples. Ten samples were evaluated using a 3D printing method, and ten samples were assessed by manual wax-up technique. Results were analyzed using Kruskal-Wallis and Mann-Whitney tests.
Results: There was a significant difference between the restoration space and the marginal edges in eight parts of the teeth in the manual method (p value < 0.001). The marginal edge space in the eight parts of the tooth was not significantly different in the 3D print method (p value = 0.614). A significant difference was observed in restoration space and the marginal edge between 3D printing and manual techniques (p value < 0.001).
Conclusion: The compatibility of the complete outer crowns of the heat press in the 3D printing method was not significantly different from the manual waxing method.

Introduction: Evaluating the dimensions of buccal and palatal alveolar bone in the anterior maxillary teeth is very important in patients who are candidates for immediate implant replacement. The aim of this study was Assessment of buccal and palatal alveolar bone thickness in maxillary anterior teeth on cone beam computed tomography (CBCT).
Materials & Methods: In this descriptive-analytical study, 78 CBCT images of patients referred to Radiology Department of Khorasgan Dental Faculty were evaluated. The collected data included the measurement of the bone thickness of the alveolar buccal and palatal anterior maxillary teeth at three locations of the crest, the middle region of the root and apex with the Sidexis software. Then, the measurements were compared between males and females. The data were analyzed by T-test statistical methods.
Results: The mean thickness of the buccal alveolar bone in the crest region and the middle region of the central, lateral and canine teeth was less than 1 mm. The mean thickness of the buccal alveolar bone at the apex site of the central, lateral and canine teeth was more than one mm. The mean thickness of the palatal alveolar bone in the crest region of the central, lateral and canine teeth was less than one millimeters. The mean thickness of the palatal alveolar bone in the middle region of the root and apex was more than one mm. There was no statistically significant difference between the sex and thickness of the buccal alveolar bone, except at the apex of the central and lateral teeth (p value > 0.05). Between sex and thickness of palatal alveolar bone, in the crest of lateral and canine teeth and in the middle root and apex area of all three central, lateral and canine teeth in men were significantly more than women (p value < 0.05).
Conclusion: The buccal alveolar bone was present in most of the points examined at the crest and mid-root site, and the palatal alveolar bone was at the crest site at most checked points with a thickness of less than 1 mm.

Introduction: The inferior alveolar canal is an important anatomical structure in the field of dentistry implants and cone beam computed tomography (CBCT) is an important diagnostic technique. The aim of this study was to evaluate the prevalence of anatomical variations of the mandibular canal observed in CBCT images.
Materials & Methods: In this descriptive-analytic study 384 inferior alveolar canals were evaluated in 192 patients, who were referred to the radiology department of Isfahan Azad University in 1396 for a cone- beam computed tomography. Radiographs were performed to assess the frequency of different left and right mandibular canal segregations by sex in terms of upper and lower position, baccolingual position, shape of the general canal. The frequency and different types of existing mandibular plug canals were also evaluated. Data were analyzed by Chi Square, independent T Test, paired t-test. (p value < 0.05).
Results: The mandibular canal was 2.1% of the lower position, 11.9% of the upper position and 86% of the middle position. Statistically significant differences were observed between the frequency distributions of canal positions and gender (p value = 0.004). The prevalence of Bifid mandibular canals was 14.8%. There was no significant relationship between the shape of the general channel path and gender. There was no significant difference between the mean distance between the mandibular canal and the buccal cortex in both Molar and Ramus with the sex of the subjects and the side of the canal (p value < 0.05).
Conclusion: The highest frequency of mandibular canal in most subjects was on the right in the intermediate position. The mean distance between mandibular canal and buccal cortex in Ramos and Molars area on both right and left sides was not significantly different between men and women.

Programs for the reconstruction of cities in the face of social, economic and environmental challenges of shaping urban areas. Purpose: The main aim of the study is to depict the characteristics of some of the most common concepts of urban reconstruction (compact city, sustainable city, smart city, as well as their hybrids), present practical aspects of the indicated urban policies and attempt to verify their implementation. Design/methodology/approach: The study is based on the presentation of selected theoretical concepts. In the empirical part, the authors use the method of case studies, presenting the effects of municipal investments and practical obstacles occurring during their implementation. They form assessments based on current media reports, articles in specialist press, as well as statements made by residents. Findings: Contemporary cities are spaces of various challenges that become sources of conflicts as well as places of unmet needs and unfulfilled ambitions. Although the decisionmakers make their decisions in connection with these challenges, their interventions are not always effective. The concepts of a compact city, a smart city and a sustainable city serve as recipes for the problems of modern cities: both the short-term ones and those which require shaping a comprehensive policy for the development of cities and urban areas. However, cities are not always properly diagnosed, and local authorities often lack specialists who could consciously and skilfully propose an optimal therapy. Originality and value: The study presents an original analysis of selected case studies which relate to the shaping of the space of Polish cities. The study focuses on the challenges of shaping urban areas in relation to contemporary trends in city planning and design determined by the importance of such issues as the quality of life of residents, the quality of space, its democratisation and sustainability, the presence of art, closed circulation or the use of modern technology and creativity in the process of managing modern cities and their space.
Koszty utrzymania mieszkań przez emerytów i rencistów na tle innych gospodarstw domowych w latach 1993-2019
Authors: Górska Anna
Published: July 2022

Housing maintenance costs for retirees and disability pensioners compared to other households in the years 1993–2019. Purpose: The aim of the study is to determine the costs of maintaining a dwelling by retirees and disability pensioners compared to other households in the years 1993–2019. Design/methodology/approach: In order to determine the amount of housing costs for retirees and disability pensioners as well as for other households, the author has collected data on the costs between 1993 and 2019 based on the publication of the Central Statistical Office (now known as Statistics Poland) entitled “Budżety gospodarstw domowych” (Household budget survey). Findings: The costs related to the maintenance of a dwelling constitute the second largest group of expenses following consumption. The cost analysis in the period between 1993 and 2019 showed a constant increase in housing costs, with the largest group of costs being those related to heating. On the other hand, the highest cost growth dynamics was related to water expenditures. The housing expenditure of retirees and disability pensioners was the highest or one of the highest among all the surveyed groups of households, which results, among other things, from the lack of adjustment of the living conditions of seniors to their needs (in terms of the number of rooms, flat area or architectural solutions), as well as from the poor technical condition of the dwellings, which also translates into higher maintenance costs. Originality and value: The issue of the cost of maintaining a dwelling by seniors is not frequently discussed in the scientific literature. The main areas of research concerning the elderly in the context of housing resources are most often related to architectural maladjustments. However, the topic of increasing housing costs in senior households is an important social problem and should be the subject of more research and analysis.

ENERGIAS RENOVÁVEIS E TERRITÓRIOS NA BACIA HIDROGRÁFICA PIANCÓ-PIRANHAS-AÇU NO NORDESTE BRASILEIRO
Authors: Maria Marinho Sales Ricélia , Gustavo de Lima Sales Luís
Published: July 2022

O ponto de partida deste trabalho consiste no compromisso mundial firmado em 2015 e que fi cou conhecido como o Acordo de Paris, chegando até a COP26 (2021) que a apresenta as energias renováveis como um caminho para combater a emissão dos gases de efeito estufa, mas sem discutir modelos e impactos socioambientais nos territórios. Assim, o objetivo geral deste artigo é dar luz à modelos de energias renováveis com fins de geração para distribuição de energia elétrica, evidenciando as especifi cidades dos territórios do Semiárido brasileiro, partindo assim do recorte espacial de uma bacia hidrográfica nacional denominada Piancó-Piranhas-Açu, que percorre os estados da Paraíba e do Rio Grande do Norte. As situações-problema constatadas possibilitou o interesse em levar a cabo uma discussão que inclua os riscos a que diferentes populações estão expostas, que, impulsionou buscar reflexões a partir da imersão teórico prática, visando o acesso às ideias e pensamentos que melhor se adeque a realidade e abordagem de modo integrado. Os resultados preliminares apontam que os elementos geoeconômicos, apesar de aparentemente isolados, podem influenciar na resiliência energética a partir dos sistemas socioecológicos e do processo adaptativo, mediante sua interconectividade direta com o funcionamento dos sistemas naturais, sejam eles vinculados aos ciclos da água, do solo e/ou do ar, mas que também despontam fatores socioculturais. Considera-se ser necessário a democratização do debate sobre o tema, da inclusão das comunidades tradicionais e da elaboração de um projeto técnico e político que tenha capacidade de reduzir as emissões dos gases de efeitos estufas, mas sem gerar novas dinâmicas territoriais de espoliação, novas cercas aos espaços vividos, sem perpetuar as injustiças socioambientais e, sem reduzir a natureza à mera prestadora de serviços para o proveito de empresas e mercados.

Published: July 2022

Este estudo tem por escopo analisar como os docentes de Geografia que atuam no Ensino fundamental do munícipio de Dois Irmão do Buriti/MS, contemplam o ensino da Geografia da Saúde, considerando os marcos legais consubstanciados na LDBEN, na BNCC e no Currículo Referência do Estado de Mato Grosso do Sul, bem como nos livros didáticos. Para tanto, elaborou-se um instrumento “online”, composto por questões relacionadas à Geografia da Saúde e ao livro didático de Geografia. Após as análises realizadas, constatou-se que apesar da Geografia da Saúde não integrar o conhecimento do professor de Geografia, se apresenta nos documentos oficiais, no currículo, bem como nos livros didáticos, sendo que na prática, não é trabalhada a contento, talvez por falta de formação continuada. Portanto, a Geografia da Saúde precisa ser trabalhada de maneira mais explícita, sob a ótica da Geografi a crítica e de forma interdisciplinar.

Chapter 17. Transforming Failure into Joyful Resilience: Discovering Fun in Failure through the Play of Theatrical Clowning
Authors: Yorke Jerome
Published: July 2022

This chapter aims to establish the possibility and necessity of the high-impact practice of theatrical clowning to be used as a tool for developing failure resiliency in undergraduate researchers. The author shows how theatrical clowning directly engages with failure stimuli through an authentic engagement with fear, play, and laughter. Pulling from theory, pedagogy, and student auto-ethnographic analysis of two case studies from the author’s course, the chapter demonstrates how clowning can be used to develop an awareness of a playful response to fear and confront failure with more resiliency.

Authors: Townsend Heather M.
Published: July 2022

This case study highlights a first attempt at implementing a course-based undergraduate research experience (CURE) and the challenges that occurred surrounding the concept of failure. It describes an introduction to the importance of CUREs, what failure is, possible solutions to confronting failure, and a brief reflection. High-impact practices such as CUREs are unique opportunities that introduce students to realistic experimental scenarios (what it feels like to be a scientist), including the potential failure inherent in the scientific process. In this case study, the author discusses her experiences with student failure and the actions taken to further prepare students for this unintended yet beneficial outcome.
Silent Spring: Landscape after sixty years
Authors: Darvas Béla
Published: July 2022

The Silent Spring is now the zero-kilometer stone of environmental movements related to plant protection, a fundamental piece of work that projects visions for us in literary English. Compared to Carson’s era, the number of pesticides that can be used has increased by sixfold. It grew from 50 pesticide active ingredients in the 1960s to over 350 in 2001-2002 and stabilized at around 250 compounds in 2008 because of the EU’s re-registration activities. Based on the findings of the Rapid Alert System of Food and Feed of the EU, more than 400 actions per year were required between 2012 and 2015 on the EU import food market due to pesticide residues. We live in the Plastic Age, and we made the planet so much lame. A catch-22 if all this is projected on overpopulation. The balance between resources and consumers is fatally damaged, pollution has caused global warming, as well as a shortage in energy and raw materials.
The importance of biological vision in the control of plant pests
Authors: Nagy Barnabás
Published: July 2022

Animal populations living on one or more plants, as well as the parasitic and predatory populations built around them, and those living from the carcass, waste, and other populations of all these plants constitute a life-changer held together by specific laws. It is therefore essential that the ratio between plant protection products, on the one hand, and entomological ecological research, on the other hand, should very soon change. Only agrocoenologists are capable to carry out the research task, which is very closely related to plant protection already that examines the immediate and more distant effects of the broad variety of protection methods, particularly those by chemical control. We allude to the agronomist, familiar with biology and not changing his farmland exceedingly often; who can gradually, year after year, compile the building blocks of experience; who can keep an eye on the major alterations in wildlife upon the anthropogenic activities that transform nature; who can record changes in the bulk of pests, their disappearance and reemergence; and who could observe the impacts of plant protection work with a critical eye. We must strive to find processes based on biological-ecological research, practically pest by pest, that allow the greatest use of natural limiting factors by restraining chemical treatments to the narrowest and most appropriate schedule. In our article, we describe some methods and principles of the implementation of a biological approach and ecological plant protection.
Examining Prospective Teachers' Ideological Beliefs and Preparation for Diversity
Authors: AÇAR Abdullah , YÜKSEL Sedat
Published: July 2022

This study aims to examine prospective teachers' ideological beliefs affecting their preparation for diversity in initial teacher education (ITE). The study was designed as qualitative phenomenology around two phenomena experienced by prospective teachers in ITE. The participants determined based on the criterion and maximum variety sampling are six senior students of an ITE program. The researchers collected via individual interviews with a semi-structured interview form. In the study, the interview questions referred to political, gender, and religious ideology categories to make participants state their views more comprehensively and concretely. The data analyzed is based on conventional content analysis in which an inductive approach takes place. The codes were created from data and hierarchized in a constant comparison process. Results showed that prospective teachers have ideological beliefs. Family, school, and social circle seem to be essential factors in building these beliefs. Although the participants indicate university as a critical factor, they emphasize that ITE does not affect their ideological beliefs. In terms of preparation for diversity, the participant has promising intentions like respecting diverse individuals; teachers need to prepare for diversity, and ITE should contribute to this preparation. However, apparent and latent barriers seem to affect their preparation negatively: prospective teachers' conditional respect attitude, being neutral concerns and some latent ideological beliefs on differences, and ITE's current no effect on preparation for diversity. Lastly, suggestions for ITE and further study are provided.
Flexible Work Arrangements and Financial Performance in Korea
Authors:   IAGBT, Choi Hyang-Mi , Park Hyun-Jung
Published: July 2022

Purpose - The purpose of this paper is to verify the effectiveness of various types of flexible work arrangements and to provide implications on financial performance. This study further examined the effects of flexible work arrangements on firm performance depending on the size of firms.
Design/Methodology/Approach - Using the panel data collected from 2016 to 2018, the study performed multiple regression analyses to analyze the effects of introduction and practical utilization of flexible work arrangements on firm performance, respectively. This study used the panel data of flexible work arrangements from the Korean Women Manager Panel Survey by the Korean Women's Development Institute.
Findings - We found that firm performance was not enhanced by mere introduction of flexible work arrangements. The empirical results provided evidence that the utilization of work from home positively affected firm performance, while the other flexible work arrangements did not have significant effects on firm performance. The findings were more evident in smaller companies, where the utilization of work from home was positively related to firm performance, and flexi-time was negatively related. For larger companies, flexible working hour utilization was positively related to firm performance.
Research Implications - The use of flexible working hours could be of help for larger companies with relatively more rigid culture. Flexi-time utilization could sacrifice financial performance for smaller firms, implying that having core hours might be more crucial for these companies to prevent potential communication problems. The use of work from home may benefit smaller companies with relatively more compact teams or a simpler structure.

The effects of cold rolling and subsequent annealing on the microstructures and mechanical properties of Fe40Mn20Cr20Ni20 high-entropy alloys (HEAs) are investigated. The Cr-rich secondary phases with a tetragonal structure (σ phases) in the Fe40Mn20Cr20Ni20 HEAs are precipitated upon annealing at 600 °C-900 °C for 2 h. The prepared Fe40Mn20Cr20Ni20 HEA annealed at 800 °C for 2 h after cold rolling has a good combination of strength and elongation, with a high yield strength of 438 MPa, a high ultimate tensile strength of 676 MPa, and an excellent elongation to fracture of 32%. The mechanical properties at cryogenic temperature are better than those at room temperature. Typically, for the incompletely recrystallized alloy annealed at 700 °C, the yield strength, tensile strength, and elongation after fracture are increased by 26%, 22%, and 100%, respectively. This trend mainly depends on dislocation and twinning strengthening. The σ phases also improve the cryogenic tensile properties. Furthermore, the recrystallization kinetics of the Fe40Mn20Cr20Ni20 HEAs are explored to correlate with the deformation behavior.

On the Variability of Benthic Foraminiferal Species of the Genus Ramulina in the Tethys
Authors: Anan Haidar Salim
Published: July 2022

Eight small benthic foraminiferal species of the Lagenid genus Ramulina are common in the Late Cretaceous and Paleogene from some Tethyan localities: North Atlantic (USA, Mexico, Caribbean); Europe (France, Germany, Czech Republic, Bulgaria, Ukraine); Northeast Africa (Egypt); Southwest Asia (Jordan, UAE, Iran, Turkmenia); and South Asia (Pakistan). These species are: Ramulina arkadelphiana, R. elkhoudaryi, R. elongata, R. futyani, R. globulifera, R. navarroana, R. ornata, and R. pseudoaculeata. Another four identified species are believed here to be new: Ramulina ismaili, R. orabii, R. plummerae, and R. salahii.
Western to Central Equatorial Pacific Planktic Foraminiferal Fluxes: Implication for the Relationship Between Their Assemblage and Warm Pool Migration from 1999 to 2002

Published: July 2022

Time-series sediment trap experiments were carried out in the western to central equatorial Pacific (Sites MT3, MT4, MT5, and MT7) from 1999 to 2002, over the transitional time period from La Niña to El Niño conditions, in order to evaluate temporal variability in planktic foraminiferal fluxes and their assemblages. The foraminiferal test flux follows a trophic gradient from higher fluxes in the Equatorial Upwelling Region (EUR) and lower fluxes in the Western Pacific Warm Pool (WPWP) region. Globigerinoides ruber commonly dominates in all sites through the experimental period. Trilobatus sacculifer, Globigerinita glutinata, and Neogloboquadrina dutertrei occurred especially in the WPWP. In contrast, Globigerina bulloides and Pulleniatina obliquiloculata characterized the fauna in the EUR.

A change in hydrologic conditions from La Niña to El Niño was documented along the sites during the sampled time interval. Simultaneous with an eastward advancement of the WPWP, the EUR retreated to the east. Rapid decreases in the fluxes of G. ruber, G. bulloides, and P. obliquiloculata were recognized immediately after the more oligotrophic WPWP conditions prevailed at Sites MT4, MT5, and MT7. Fluxes of the total planktic foraminifer assemblage increased both in the EUR and in the western side of the WPWP under full El Niño conditions during the second half of 2002. Such increases in test fluxes in the western side of the WPWP were mainly attributed to G. ruber and N. dutertrei, suggesting inputs of eutrophic waters from the northern coastal area of Papua New Guinea. Test fluxes under El Niño conditions in the WPWP were at the same level as those in the EUR, giving rise to strongly increased carbonate fluxes in the western equatorial Pacific.

Studying variation in genes responsible for physiological characters is important to enhance goat productive and reproductive efficiency. This study aimed to detect specific nucleotide polymorphisms in Prolactin receptor (PRLR), Insulin like growth factor (IGF1) and Leptin (LEP) genes and their correlation with milk production (MP) and litter size (LS) traits in Zaraibi goat. PCR-SSCP products of different patterns of each gene were sequenced and aligned to reveal two single nucleotide polymorphisms (SNPs) (T > C) and (G > A) in 3’UTR of PRLR gene and registered on NCBI with accession numbers OM418863 for TT and OM418864 for CT, while (G > A) SNP was registered as OM418861 for GG and OM418862 for AG in exon 10. TT, CT, AG and GG genotypes were distributed in the studied animals with frequencies 0.43, 0.57, 0.65 and 0.35, respectively. While alleles C, T, A and G frequencies were 0.28, 0.72, 0.32 and 0.68, respectively. CT and AG genotypes associated significantly (P < 0.05) with higher MP and LS respectively. By studying the haplotypes of PRLR, C-A and T-A were associated with the highest and the lowest level of MP respectively. For LS, T-A and C-G showed significant correlation with the highest and the lowest rate respectively. Regarding IGF1 gene, two SNPs were detected; T74C at exon 4 which registered on NCBI as (OM418860), and combined SNPs as ins. G470, A531G and T534C (PP genotype) at 5’ flanking region that registered as (OM418859). For LEP, only one SNP was found in intron 2 (G281A) which submitted to NCBI as (OM418855). All detected SNPs have shown to be involved in regulating the MP or LS as reproductive traits in goat.
