The Role of Prophylactic Antibiotics in Newborn Born through Meconium Stained Amniotic Fluid (MSAF)
Authors: Chaurasiya Om Shankar
Published: January 2024

Objective: The objective of the study was to evaluate the effect of administering prophylactic antibiotics on the development of neonatal sepsis in newborn born through meconium stained amniotic fluid (MSAF). Method: Total 200 babies born through meconium stained amniotic fluid were included in this study. 100 babies randomized to group a (antibiotic group) received first line antibiotics for 3 days and 100 babies to group B (no antibiotic group) in which no antibiotics were given. Both group A and B evaluated clinically and by lab parameters (sepsis screen and blood cultures) for development of sepsis. Both groups received similar supportive management. The primary outcome measure was the development of infection. Details of clinical progress during were recorded. All neonates were monitored for development of complications Result: The patient profiles were similar in both groups. The overall incidence of suspect sepsis was 9 % in the study population with no significant difference between group A and group B (7 %vs. 11 %, p=0.322). Incidence of culture-proven sepsis was also not significantly different between the two groups (5% vs. 7 %, p=0.3546). The incidence of mortality, meconium aspiration syndrome, and other complications was comparable amongst the two groups. Final outcome and duration of stay was also not significantly different in both group A and group B. Conclusion: This study shows that there was no statistically significant difference in the incidence of development of infection, complication and final outcome in neonates born through meconium stained amniotic fluid when treated with or without antibiotics.
Contemporary Sedation Training in Advanced Pediatric Dentistry Programs: Shortcomings and Unrealistic Expectations
Authors: E Nathan John
Published: January 2024

If asked to describe the extent to which pediatric dental residents and postgraduate students experience successful outcomes when using oral sedation, their responses are correspondingly low, unimpressive if not surprising. This editorial focuses on the basis of such outcomes and suggests needed updates in sedation curricula and clinical applications.
An Aberrant Position of Peripherally Inserted Central Venous Catheter in Extreme Preterm Infant
Authors: Sakharkar Sachin
Published: January 2024

The use of a Percutaneously inserted central catheter (PICC) has increased with improved survival of extremely premature infants. Catheter malposition and perforation are associated with serious complications. PICC line position always needs to be confirmed after insertion. An Anteroposterior (AP) view radiograph is commonly used to confirm catheter tip position. We report a case of an unusual PICC position despite confirmation of the PICC tip position on the AP view radiograph. It is a potentially fatal complication and timely intervention can be lifesaving. Performing lateral X-rays to confirm the PICC tip or USG-guided placement of the catheter tip can prevent untoward serious complications. In the case of ascites, upper-extremity catheter insertion should be preferred instead of lower-extremity central venous catheters.
Neonatal Withdrawal Syndrome: A Diagnosis to Keep in Mind
Authors: Vala Beatriz
Published: January 2024

During pregnancy, women are put through many challenges, sometimes facilitating the appearance of depression and anxiety symptoms, leading to the use of psychotropic drugs like benzodiazepines. We present the case of a male new born who presented breathing distress signs during the first hour of life, needing supplemental oxygen. His mother was diagnosed with depressive syndrome and anxiety and was medicated with escitalopram until six months of pregnancy and diazepam as needed until the end of gestation. He was admitted to the Neonatal Intensive Care Unit. In the first 12 hours of admission, he started with irritability, difficulty calming, and exaggerated Moro reflex. Blood tests, lumbar puncture, and cultures were performed, and antibiotics were started. During the first five days of admission, while on antibiotics, he also presented poor sucking reflexes, altered stools, hyper alert look, hyperreflexia, and jitteriness episodes, with low blood inflammatory markers. Withdrawal syndrome was considered after blood and cerebrospinal fluid cultures were negative, and no improvement of the neurological status with antibiotics. He was monitored with Finnegan’s score and improved with containment and comfort measures. This case pretends to emphasize the importance of adequate psychiatric follow-up during pregnancy and of awareness among neonatologists and pediatricians regarding the medicines that can be related to withdrawal syndrome.

Published: January 2024

English is an international language used by the global community from various countries to communicate with each other by default. However, not all people living in tourism areas, including schoolchildren, have fluent English skills. Even though school children are the next generation, who will later develop tourism potential in the area, this service provides English language training to elementary school students in potential tourism areas in Belitung Regency. The community service method is in the form of pronunciation training and short conversations in English, delivered in English games and songs. As a result, children become more proficient in vocabulary and communicating briefly in English. The results of this study indicate that children can quickly master foreign languages if their learning is in the form of fun games or songs. So that English skills can begin to be applied to children and later will make it easier for them to communicate with foreign tourists who stop at these tourist sites.

eficácia social do direito à educação na pandemia de covid-19 no brasil:
Authors: Leite Beloni dos Santos Giulia
Published: January 2024

Os direitos fundamentais são aqueles que visam a proteção e garantia da dignidade da pessoa humana. A segunda geração dos direitos humanos deu ênfase aos direitos sociais, dentre eles, o direito à educação. A Constituição Brasileira, em seu artigo 6º, deixa clara a importância que o legislador deu para a garantia desse direito. Contudo, sabe-se que a eficácia desse direito na realidade fática fica aquém do necessário, reiterando a necessidade de pesquisa sobre o assunto, pois se trata de direito previsto no documento jurídico máximo do país. A pesquisa propõe-se a analisar e conceituar os direitos sociais, a eficácia do direito à educação no Brasil antes da pandemia de COVID-19 e como a pandemia afetou essa eficácia. Utiliza-se o método hipotético dedutivo, demonstrando como a eficácia social do direito à educação ficou aquém do desejável durante a pandemia de COVID-19, no Brasil.
Direito e marxismo:
Authors: Veloso Mateus Lima
Published: January 2024

O direito como pratica humana remonta até as sociedades mais antigas, contudo, com a evolução social e o aumento da complexidade das relações de dominação entre as classes, o direito deixou sua natureza primaria como regulador social simples, para se tornar um instrumento de dominação burguesa contra o proletariado. Tal relação entre direito e a ideologia dominante é analisada desde o século XIX, chegando ao seu apogeu teórico no trabalho critico de Evguiéni B. Pachukanis e a sua critica ao modelo teórico tecnicista burguês hegemônico de Hans Kelsen, que consiste na retirada da práxis e no reforço da visão liberal de justiça.

Authors: Lagonegro Marcello , Almeida Cátia Cristina Benevenuto de
Published: January 2024

Este artigo tem como objetivo demonstrar como o compartilhamento da curatela contribui para a superação da segregação familiar. Para tanto, no Título 1º, será analisada a nomeação de curador provisório, geralmente oriundo do meio familiar. Como efeito deste acontecimento, no Título 2º, será analisada a intervenção judicial motivada por desavença intrafamiliar, como forma de se remover o curador provisório e, em seu lugar, nomear outro, um curador dativo extrafamiliar. Em decorrência destes acontecimentos (e de modo sintético), no Título 3º, será sugerido que, quando o juízo adota a curatela compartilhada, ele propicia a resolução da segregação familiar, superando estas duas modalidades precedentes de curadoria (provisória/familiar e dativa) e, desse modo, vai o compartilhamento se constituindo como fator de inovação do instituto.
Evaluation of the Percentage of Crown Effect Losses on the Whole Cameroonian Transmission Network Compared to the Joule Effect Losses
Authors: Tchado Ngueko Didier Rostan , Boukar Ousman , Ngasop Ndjiya
Published: January 2024

In this paper, we have estimated the losses on the electric transmission lines of the Cameroonian Southern Interconnected Network (RIS) and Northern Interconnected Network (RIN) by collecting data on the network and line parameters for the 225 kV circuit of the RIS and 110 kV circuit of the RIN from Energy of Cameroon (ENEO) on the one hand; on the other hand, we have carried out simulations while studying the influence of the different parameters such as the transported power, the meteorological conditions, the characteristics of the network and the transport distance on the electric losses in our different transmission lines. This was achieved through a thorough review of technical loss analysis methods, conducting power loss studies on each 225 kV RIS and 110 kV RIN line, using appropriate mathematical models for power line loss assessment, graphical interpretation of the various simulated models, and quantitative loss assessment. It was found that crown losses are about 2.55 times higher in the RIS than in the RIN; poor weather conditions and the level of voltage carried favour crown discharge, thus increasing losses. As for the Joule effect losses, they are about 6.54 times higher in the RIS than in the RIN. From this study, we can see that on the whole of the Cameroonian electricity network, crown losses are negligible compared to joule losses.

Authors: Caramori Gabriel Moura , De Almeira Lucas Martins Miranda , Da Costa Cesar
Published: January 2024

This study proposes an enhanced method for estimating the position of a permanent magnet synchronous motor (PMSM) using the Luenberger observer and phase-locked loop (PLL) algorithm. The main contribution to this research is the use of two low-pass filters (LPF) at the input of the PLL, which results in softer position reconstruction compared with conventional PLL. The proposed method is designed and simulated using the MATLAB/Simulink platform. The performance of the proposed method was evaluated and compared with conventional PLL and PLL with one LPF using several performance metrics such as estimation accuracy, convergence time, and stability. Simulation results show that the proposed method achieves better estimation accuracy and higher stability compared with the other methods. Additionally, the proposed method is robust to various disturbances such as load torque and parameter variations. Overall, the proposed method offers an effective and efficient solution for estimating the position of PMSM in various industrial applications.

JOB BURNOUT AND SATISFACTION AMONG SECONDARY TEACHERS: REGRESSION AND K-MEANS CLUSTERING ANALYSIS
Authors: Casinillo Leomarich F , Malquisto Irene R , Salabao Analita A , Tavera Ginna F
Published: January 2024

Burnout on a teaching job refers to exhaustion that leads to depression which can affect the teacher’s well-being and satisfaction. This article looks into the level of job burnout and satisfaction of high school teachers during modular distance learning and determines its association at different levels. Cross-sectional primary data were gathered from a random sample of secondary teachers in Ormoc City, Leyte, Philippines. The gathered data were job burnout and satisfaction scores and described using standard statistical metrics. Moreover, correlation and regression analysis were employed to analyze its association, and K-means clustering was used to identify homogeneous categories of job burnout and satisfaction scores with similar characteristics. On average, results showed that the high school teachers were still  “satisfied” despite the “high burnout” they were facing during the modular distance learning amid the pandemic. Using the correlation analysis, it is revealed that teachers’ satisfaction and burnout are significantly and inversely correlated to each other. This implies that the burnout level adversely affects the satisfaction in teaching. Based on regression analysis, there is a decrease of 0.653 units in the satisfaction perception score for every 1 unit increase in the burnout perception score and it is significant at a 1% level. It is depicted in K-means clustering that teachers’ satisfaction and burnout levels are compact and converge to the interpretation that they were highly burnout yet satisfied in modular distance learning. Hence, the study suggests that teachers' tasks during distance education must be lessened to increase their well-being as educators.

Journey to the East. What is happening in the Chinese audio description (AD) world? An interview-based study
Authors: Liu Yuchen
Published: January 2024

A pesar de la existencia de la audiodescripción (AD) en China desde 2005, se sabe poco sobre cómo se lleva a cabo la AD en China debido a la escasez de estudios sobre este tema. Este artículo, basado en entrevistas semiestructuradas con seis proveedores chinos de AD de Shanghái, Wuxi y Guangzhou, tiene como objetivo reducir esta brecha de conocimiento y presentar cómo se realiza la AD en la China continental, de acuerdo con la opinión de algunos de los agentes clave involucrados. Las entrevistas se realizaron entre el 30 de abril y el 13 de julio de 2020 a través de llamadas de voz por WeChat. Los resultados se pueden agrupar en las siguientes tres temáticas: el estado actual de la AD en China, cómo se lleva a cabo AD en China y la viabilidad de la traducción de la AD del español al chino. Este estudio ha llegado a dos conclusiones principales. Primero, la AD en China está, en este momento, llena de oportunidades y desafíos, con el tema de los derechos de autor como su principal problema y la dicotomía objetividad frente a subjetividad como una de las cuestiones más debatidas en la elaboración de los guiones. En segundo lugar, casi todos los entrevistados mostraron una actitud positiva hacia la propuesta de traducir la AD, en nuestro caso particular del español al chino, como forma alternativa de promover este servicio en China.

Published: January 2024

Information seeking leads to interactions within a system. At the same time, interaction patterns can potentially lead to a behavioral tendency and form a unique behavioral pattern. This research aimed to find out how information search behavior was carried out by students of the Library and Information Science Study Program in conducting literature searches on the Google Scholar platform by applying the stages of the Ellis Model. The research method used quantitative with a survey method. The results showed that at the starting stage, the correlation coefficient was moderate; at the chaining stage, the correlation coefficient was moderate; at the browsing stage, the correlation coefficient was below moderate; at the monitoring stage, the correlation coefficient was below moderate; at the differentiating stage, the correlation coefficient was moderate; and at the extracting stage, the correlation coefficient was below moderate. This study concludes that students know the topic they want to search before using Google Scholar. Chaining, browsing, and monitoring are done alternately at almost the same time. Students have observed the correlation coefficient numbers at the chaining, browsing, and monitoring stages; students pay more attention to the chaining stage, namely obtaining keywords. At the differentiating stage, students have begun to filter incoming information and use their ability to distinguish the sources of information obtained, and at the extracting stage, students work through the selected sources to identify all relevant materials.

Authors: Ejeta Lucky Ogheneakpobo , Elimian Ehiaghe Agbovhimen
Published: January 2024

Solid waste has become a major environmental concern globally in recent years due to the tremendous increase in waste generation. However, these wastes (e.g., plastics and agro-residues) can serve as potential raw materials for the production of value-added products such as composites at low cost. The utilization of these waste materials in the composite industry is a good strategy for maintaining the sustainability of resources with economic and environmental benefits. In this report, the environmental impacts and management strategies of solid waste materials are discussed in detail. The study described the benefits of recycling and reusing solid wastes (i.e., plastic and agro-waste). The report also reviewed the emerging fabrication approaches for natural particulate hybrid nanocomposite materials. The results of this survey reveal that the fabrication techniques employed in manufacturing composite materials could significantly influence the performance of the resulting composite products. Furthermore, some key areas have been identified for further investigation. Therefore, this report is a state-of-the-art review and stands out as a guide for academics and industrialists.

Koizumi Yakumo: Traducción de "El devorador de sueños"
Authors: Perdomo Morales Juan Camilo
Published: January 2024

"El devorador de sueños" es un cuento de Lafcadio Hearn, Koizumi Yakumo, publicado en 1903 en Kott?, una colección de leyendas del folclore japonés recopiladas a partir de fuentes orales y libros tradicionales. Aquí, Hearn nos presenta la criatura del Bakú, un ser mitológico creado por los dioses con las partes sobrantes de otros animales tras la Creación. Su origen se remonta a China, donde se creía que se alimentaba de malos espíritus. Al llegar a Japón, mantuvo esta función, mutando, poco a poco, en un devorador de sueños malignos, de pesadillas, que protegía a los soñadores de la mala fortuna. El Bakú es un yokai cuya clara impronta en la cultura japonesa aún es visible, por ejemplo, se cantan canciones de cuna sobre él antes de dormir o es posible encontrar amuletos tallados con su figura. No siendo más, presentamos esta destacada historia de Hearn cuyo propósito fue presentar al lector occidental la sacralidad del Bakú, su relevancia e influencia en la vida cotidiana nipona y la profunda conexión espiritual de los japoneses con dioses, espíritus y seres sobrenaturales.

The selected agrotechnical factors affecting the occurrence of black grass Alopecurus myosuroides in winter wheat crops in north-western Poland
Authors: Wróbel Mariola , Jaroszewska Anna , Podsiadło Cezary , Sobolewska Magdalena
Published: January 2024

Alopecurus myosuroides of the family Poaceae is a highly competitive species for winter cereal crops, particularly for barley and wheat, less frequently for root vegetables or rapeseed. This study aimed to determine the predominant factor or group of factors affecting the cover of A. myosuroides in winter wheat field depending on the tillage systems, time, and amounts of herbicides used. The following variables differentiating the quantitative contribution of A. myosuroides in the analyzed fields were assumed: plough or no-plough tillage, date of biocidal application, and the total amount of herbicides (active substances) used. When spring-only herbicide was applied, the lowest A. myosuroides cover, not exceeding 25%, was observed in the margins of winter wheat fields. The coverage of A. myosuroides, reaching 25–100% of the winter wheat area, regardless of the tillage system, was found when the herbicides from the group of sulfonylurea derivatives (acetolactate synthase ALS inhibitors) were frequently used. Winter wheat infestation with A. myosuroides was significantly lower when ploughing was applied. The highest cover of A. myosuroides, reaching 50–100% of the area, was observed only in the central part of the analyzed winter wheat fields, following the application of herbicides in autumn and spring or in autumn only.

Published: January 2024

Badania polowe przeprowadzono w latach 2018–2020, w Rolniczej Stacji Doświadczalnej w Zawadach, należącej do Uniwersytetu Przyrodniczo-Humanistycznego w Siedlcach. Eksperyment prowadzono w trzech powtórzeniach, w układzie split-plot, na lekko kwaśnej glebie należącej do kompleksu żytniego bardzo dobrego. Badania obejmowały dwa czynniki. Pierwszy czynnik (I rzędu) – dwie odmiany ziemniaka jadalnego: Oberon i Malaga. Obie odmiany należą do średnio wczesnych, o pokroju liściowo łodygowym. Drugi czynnik (II rzędu) – pięć sposobów pielęgnacji ziemniaka z wykorzystaniem zabiegów mechanicznych, herbicydu, biostymulatorów oraz z zastosowaniem herbicydu i biostymulatorów. Celem pracy było zbadanie wpływu stosowania herbicydu oraz jego kombinacji z biostymulatorami na skład gatunkowy i liczbę chwastów. Przy wykorzystaniu metody ramkowo-wagowej określono średnią liczbę chwastów na 1 m2 oraz ich skład gatunkowy. Herbicyd Avatar 293 ZC i biostymulatory Agro-Sorb Folium oraz PlonoStart istotnie zmniejszyły zagęszczenie chwastów na 1 m2 w dwóch terminach oznaczeń, w porównaniu z obiektem kontrolnym. Zastosowanie herbicydu Avatar 293 ZC i biostymulatora Agro-Sorb Folium w największym stopniu ograniczyło występowanie takich gatunków chwastów, jak: Echinochloa crus-galli (chwastnica jednostronna), Chenopodium album L. (komosa biała), Polygonum aviculare (rdest ptasi) oraz Viola arvensis Murr. (fiołek polny). W pierwszym terminie oceny zachwaszczenia, tj. przed zwarciem rzędów, odnotowano większą liczbę chwastów niż tuż przed zbiorem bulw ziemniaka. Odmiany ziemniaka nie miały istotnego wpływu na zachwaszczenie uprawy.
Extended septal myectomy for obstructive hypertrophic cardiomyopathy and its impact on mitral valve function
Authors: Lio Antonio , D’Ovidio Mariangela , Chirichilli Ilaria , Saitto Guglielmo , Nicolò Francesca , Russo Marco , Irace Francesco , Ranocchi Federico , Davoli Marina , Musumeci Francesco
Published: January 2024

Aims

Septal myectomy is the treatment of choice for hypertrophic obstructive cardiomyopathy (HOCM). Around 30–60% of patients with HOCM have a secondary mitral valve regurgitation due to systolic anterior motion (SAM). We report our experience with extended septal myectomy and its impact on the incidence of concomitant mitral valve procedures.

Methods

This is a retrospective study on 84 patients who underwent SM from January 2008 to February 2022. Surgical procedure was performed according to the concept of ‘extended myectomy’ described by Messmer in 1994. Follow-up outcomes in terms of survival, hospital admissions for heart failure or MV disease, cardiac reoperations, and pacemaker (PMK) implantation were recorded.

Results

Mean age was 61 ± 15 years. Mitral valve surgery was performed in seven cases (8%); particularly only one patient without degenerative mitral valve disease underwent mitral valve surgery, with a plicature of the posterior leaflet. In-hospital mortality was 5%. Mitral valve regurgitation greater than mild was present in four patients (5%) at discharge. Twelve-year survival was 78 ± 22%. Cumulative incidence of rehospitalization for heart failure and rehospitalization for mitral valve disease was 10 ± 4 and 2.5 ± 2.5%, respectively. PMK implantation was 5% at discharge, with a cumulative incidence of 15 ± 7%. Freedom from cardiac reoperations was 100%.

Conclusion

Septal myectomy for HOCM is associated with good outcomes. Although concomitant surgery on the mitral valve to address SAM and associated regurgitation has been advocated, these procedures were needed in our practice only in patients with intrinsic mitral valve disease. Adequate myectomy addresses the underlying pathophysiology in most patients.
Genetics of Tooth Size
Authors: Townsend Grant C.
Published: January 2024

This paper summarises the findings of a genetic study of tooth size in a group of Australian Aboriginals. Measurements were obtained from a total of 392 dental casts collected as part of a longitudinal growth study of Aboriginals living at Yuendumu, a settlement town in the Northern Territory of Australia. Family data were compiled from genealogical records gathered over a number of years. The custom of polygyny practised by the Yuendumu people enabled the analysis of associations between both full-siblings and half-siblings.

Similarities between related individuals were expressed in terms of correlation coefficients. Values of average correlations for both mesiodistal and buccolingual dimensions conformed with the theoretical correlations expected assuming autosomal polygenic inheritance. No evidence of sex chromosomal involvement was found. Heritability estimates for permanent tooth size were derived and the contribution of common environment to the observed phenotypic variability estimated. Results obtained from full-sibling, half-sibling and parent-offspring data suggested that approximately 50 to 60 per cent of the total variability of permanent tooth size could be attributed to additive genetic effects, while an additional 14 per cent was due to common environment.

Although the genetic contribution to tooth size variability is high, the findings have indicated that non-genetic factors also play an important role in the determination of this metric character.
Cephalometric appraisal for craniofacial Imbalances in orthodontic & surgical anomalies
Authors: Darryle Bowden B.
Published: January 2024

The clinical application of a cephalometric analysis developed to define the areas of craniofacial imbalance is described. Data was derived from computer analysed serial data from lateral radiographs of 60 boys and 64 girls from 2 to 20 years of age and from other surgical and orthodontic cross sectional data. The cephalometric analyses are illustrated on a “normal” 18 year old female and on a 24 year old male with a maxillary deficiency and with severe mandibular overclosure, pre and post operatively. The methodology determines variations in cranial base, orbit and zygoma positions, craniofacial divergence, maxillary and mandibular positions, relations and size, dental arch size and position and the effects of the combined parameters on the soft tissues of nose and lips.

The Begg-Edgewise Diagnosis Determined Totally Individualized Orthodontic Technique was developed in an attempt to assimilate and enhance the best aspects of the Begg and various Edgewise techniques, and to eliminate their deficiencies. The appliance is a combination of six different narrow brackets with horizontal slots (.022″ × .028″) and 0°, 3°, 7°, 11°, 17° and 22° degrees of torque. The brackets have a vertical, slot (.020″ × .020″) for auxiliary springs. In some cases double Edgewise buccal tubes (.022″ × .028″) on molar teeth are used with about 24° of angulation between the two tubes; triple tubes may be employed if required in the upper arch for extra-oral force. The appliance is illustrated with the records of seven cases presented, including non-extraction and extraction treatment plans. The cases illustrate the technique’s utilization in minimum, moderate and maximum anchorage situations, and various combinations of elastics, together with sectional Edgewise wires. The use of square and ribbon arch wires in preference to Edgewise configurations is also discussed.

Orthodontic silver brazing alloys suffer from the presence of cadmium, excessive flow temperatures, and crevice corrosion on stainless steel. Seven alloys were examined. Two alloys contained cadmium. The lowest flow temperature observed was 629°C for a cadmium alloy and 651 °C for two cadmium free alloys. Three alloys had corrosion resistance superior to the other solders. Addition of low melting temperature elements gallium and indium reduced flow temperature in some cases but produced brittleness in the brazing alloy.
Early relapse following sagittal split advancement
Authors: Richard Hing N.
Published: January 2024

Early relapse following bilateral sagittal split advancement (BSSA) was assessed by evaluating the cephalograms of 47 patients. The records were assigned to either screw fixation (SF: n=25) or wire osteosynthesis (WF: n=22) groups and subdivided if additional Le Fort I osteotomy was performed. 9 skeletal parameters were evaluated. The results showed that there were relatively minor differences between the screw and wire osteosynthesis groups in the first 6 weeks following surgery. Relapse of 11 percent and 22 percent was recorded respectively but this difference was not statistically significant.

Relapse was not correlated with the preoperative mandibular plane, altered posterior facial height, gonial angle or changes in gonial arc radius in either group. A clear association between condylar displacement and relapse tendency was not expressed. This suggests that whilst condylar position remains important, early postsurgical relapse is due to multifactorial influences.

Published: January 2024

An in vitro evaluation of bond strength of a glass polyalkenoate cement to human dental enamel and stainless steel is reported. Shear testing of adhesive strength was measured over time at 23°C following a one minute mixing time.

It was found that there is a significant difference in bond strengths between enamel and stainless steel with strength to enamel the greater. Bond strength increases with time with very low strength measured within 30 minutes from commencement of mixing.
Intrusion and apical resorption of mandibular incisors in Begg treatment: anchorage bend or curve?
Authors: Lew Kenneth
Published: January 2024

A statistical evaluation of the apical root resorption in mandibular incisors following Begg treatment in one group with anchorage bends and another group with anchorage curves showed no statistical difference. Although the overbite reduction in both groups were similar, the anchorage curve group was statistically more efficient in incisor intrusion when compared to the anchorage bend group (p<001).
Towards a revised undergraduate orthodontic curriculum

Published: January 2024

The undergraduate curriculum in Dentistry at the University of Queensland, as elsewhere, is under scrutiny. Developments in the tertiary education system, and changes in the profession of dentistry have to be taken into account. Orthodontics is a specialty area which is particularly affected by these pressures.

This paper describes the conduct, results and implications of a survey undertaken to ascertain the attitudes of practising dentists towards their own orthodontic education and their perceived needs in continuing education. Data was obtained from a substantial sample of those present practitioners who are registered and are practising in Queensland, the majority having graduated from the University of Queensland.

In business, quality has demonstrated to be troublesome to characterize. Numerous people relate quality with a few degrees of enormity or common prevalence, whereas others see it as basically the nonattendance of fabricating blemishes. The American National Benchmarks Established (ANSI) and the American Society for Quality Control (ASQC) built up the official definition of quality in 1978.

Concurring to the overview, either the administration and parent company inside or the client remotely give these businesses with the inspiration to execute quality control. Due to a need of specialized understanding, the businesses are not utilizing six sigma strategies or capability ponders. The capacity to degree item determination satisfaction, the comfort of utilize of the procedure, and the capacity to address squeezing quality and efficiency issues are the three contemplations that these companies consider when choosing a quality control approach.
Finite Difference Method for Solving the Two-Dimensional Laplace Equation in Curvilinear Coordinates
Authors: Tcaciuc Gabriel-Dumitru , Popescu Aristotel
Published: January 2024

This paper presents a numerical method for solving the two-dimensional Laplace equation in curvilinear coordinates using a finite difference scheme. Laplace equation is a differential equation used to describe various physical phenomena studied within different branches of engineering. The two-dimensional Laplace equation has analytic solutions only for simple shaped domains and simple boundary conditions (first and second kind). Even so, the results are usually complicated to interpret and use. The present paper proposes a method to solve the equation for domains bounded by complex inner and outer curves. The boundary curves are defined by a set of points from which the equations of curves are approximated by using Fourier series. The domain is generated by blending the two curves using a blending function. The results are a set of continuous parametric equations which are defining the domain in angle and radius variables. Following a method presented in the literature, the Laplace equation is transformed from Cartesian coordinates to curvilinear coordinates, as the Fourier series is easily differentiable. Next, the new Laplace equation is approximated using the finite difference method and a MATLAB code is developed to solve the system of linear equations using successive over-relaxation method (SOR). The presented method is used to simulate steady two-dimensional heat conduction in a polygonal shape domain, with uniform and non-uniform Dirichlet boundary conditions. Results are analyzed in order to determine the model’s precision, speed and convergence criteria.

Published: January 2024

This research in progress paper investigates the multifaceted factors shaping the work-related attitudes of top managers in organizations with a focus on Germany. Through in-depth interviews with seasoned experts, it reveals crucial work attitudes, examines the impact of interpersonal and procedural factors, and evaluates information’s role in the principal-agent relationship at top management levels. The findings challenge conventional assumptions, providing different perspectives on leadership and highlighting the evolving nature of management practices in the digital age. The study also explores potential differences between top IT managers and other C-level roles, investigating their implications.

The results of this research based on expert interviews are used in a broader context of research to triangulate literature analysis findings and quantitative surveys in order to develop a comprehensive understanding of factors influencing top managers’ work attitudes. Semi-structured expert interviews were conducted to gain a comprehensive perspective on the influencing factors of work attitudes in top management functions. Six German experts participated, bringing diverse backgrounds and affiliations with professional associations. Despite varied perspectives, universal importance was identified in key work attitudes, challenging assumptions of significant differences between employer and employee representatives. A novel contrast between hierarchical and broader perspectives within owner and worker associations emerged, suggesting a need for a more comprehensive understanding of management approaches. Additionally, interpersonal factors in leadership, information flow, trust-building, were highlighted as contributions. Furthermore, distinctions and commonalities between IT management and other top managerial roles were identified. This study both confirms existing knowledge and introduces valuable insights to management science, potentially shaping future research and practices.
IMPLICATIONS OF VIRTUAL REALITY IN D„EVELOPING TOURISM - THE CASE OF TRANSYLVANIA, ROMANIA
Authors: Ticau Iulia Ruxandra
Published: January 2024

Technological advancements are constantly changing developing industries and impacting all players in the field. Among the most well-known revolutionary technologies is virtual reality (VR), a three-dimensional concept that offers its users the possibility to simulate new environments by visualizing the real world from their own location. This research article raises the question of the extent to which such technologies can influence the tourism potential of a much-discussed region in Romania, namely Transylvania. As a result, case study research with qualitative data was conducted, leading to an extended analysis of the current topic. By adopting a threefold division of VR’ potential destination: marketing tool, planning and managerial and entertainment tool, the study aimed at providing relevant insights upon the importance of VR for both service providers in the field, but also potential beneficiaries of touristic services. The results show that VR is of great benefit to the development of the tourism industry, but that factors such as costly implementation costs and "resistance" to innovation can occur. The research findings have implications for researchers in the field, but also for stakeholders in the tourism and technology sectors.
