Published: June 2024

Business Education programme in Nigeria requires a proactive and effective assessment that can bridge the gap between theory and practice. This will go a long way in ensuring the correlation between skills and competency displayed by graduates of business education and the certificate they obtain to parade looking for white-collar jobs in the world of competition. This can only be achieved through a well-structured and update of business education curriculum. The curriculum development process include: curriculum content with details of what the teachers are expected to teach and each students expected to learn. Business education graduates should be able to put to practice the skills professed by their certificates. The study examines, concept of curriculum development, types of curriculum development models, principles of curriculum development, trends that will shape curriculum development. Some of the challenges in enhancing the implementation of business education curriculum are; Inadequate funding of business education programme, Poor maintenance of business education equipment, unstructured curriculum in business education and inadequate qualified lecturers. Among others, it was recommended that the university authorities should adequately fund Business education Programmes to enable them have a required facilities for effective teaching and learning and employing adequate qualified teachers to teach in business education programme

Published: June 2024

Actualmente, los sistemas de información están presentes en todos los aspectos de nuestra vida, y las pequeñas y medianas empresas no son la excepción. Sin embargo, muchas aún carecen de un sistema eficiente y confiable para administrar su información. Este trabajo se centra en la metodología Test Driven Development (TDD), con el objetivo de identificar sus ventajas en la construcción de sistemas. TDD es una metodología de desarrollo de software basada en pruebas para guiar el proceso. Los resultados muestran que TDD, integrada en el framework JUnit, no solo cubre el testing de la aplicación, sino que también promueve un diseño óptimo y eficiente. Esto mejora la codificación del software, resultando en un código más tolerante al cambio, robusto y seguro. Tras analizar las ventajas de TDD y los principios de Scrum, se desarrolló e implementó un prototipo de sistema de control de inventario utilizando Java SE y MySQL. Este prototipo permitirá optimizar los procesos de compra, venta y control de productos de cualquier PYME.

Published: June 2024

Currently, golf cars as a means of transportation vehicles have been used at large universities spread over large areas, expensive hotels and housing complexes and most recently for travel comfort, namely in the hotel industry. Theoretically, aerodynamic drag on transportation vehicles contributes around 50-60% to vehicle fuel consumption. The aim of this research is that by utilizing the upper-side inclination angle of the golf car, it can reduce aerodynamic drag and automatically reduce vehicle fuel consumption. In this paper, the effect of upper-side inclination angle on aerodynamic loads on a golf cart (i.e. total pressure, turbulence kinetic energy, velocity contour, and drag force) is investigated using 3D Computational Fluid Dynamics. The results of the research show that at the same speed, the greater the upper-side inclination angle of a golf cart the greater the drag force obtained. A tilt angle of 600 with a speed of 20 km/h produces the lowest drag force value. When compared to standard (00 tilt angle) the reduction in drag is around 38.06 %. In conclusion, that 3D Computational Fluid Dynamics can simulate the influence of the upper-side inclination angle on the aerodynamic load from the golf cart.

Published: June 2024

This research aims to examine the effects of a heat source or sink and viscous dissipation on an MHD unsteady three-dimensional Casson fluid flow across a stretched sheet. Using similarity transformations, the governing partial differential equations are transformed into coupled ordinary differential equations, which are then solved numerically in Matlab. The numerical findings for several physical parameters that impact velocity and temperature profiles are described in tables and graphs. The interesting finding are recorded as follows: When the Magnetic parameter increases, the skin friction coefficient increases along x and z directions, but when the Casson parameter lowers, it decreases. The Nusselt number increases with the enhancement of viscous dissipation parameter and heat source or sink parameter. Understanding the behavior of non-Newtonian fluids in the presence of heat transfer is crucial in a number of domains, including chemical engineering, biomechanics, and material processing. These applications might benefit from this kind of study.

Authors: Nur Fatinhanani Fatimah Norsham  , Istikamah Subuki
Published: June 2024

Polymorphic zirconia is economically attractive in various applications due to its low reactivity, high strength, and stability. Zirconia can be synthesized from locally available Amang zircon sand as an inexpensive green alternative as it has a high zirconium content as reported by previous report. Unfortunately, the study was only focused on the formation of zirconium oxychloride despite of high zirconium content from the improved alkali fusion method proposed. Therefore, a further study on zirconia powder calcined in varied temperatures from Amang zirconium oxychloride precursor was done. Amang zirconia powder was then characterized in order to study the effect of temperature on Amang zirconia powder. Elemental analysis showed that zirconium composition was affected by temperature and increased as the temperature increased with the highest zirconium content of 81.28 wt.% with low impurities after calcined at 800 °C for 4 hours. The phase analysis satisfied monoclinic zirconia with minor tetragonal and cubic phase with sharper peaks as calcined temperature increased. Increased tetragonal and cubic phase was observed as the temperature was increased. Morphology analysis showed zirconia powder was angular and pyramidal with large crystal size which led to high tendency of monoclinic phase. Calcination temperature of 800 °C was determined to be the most suitable temperature to calcine high purity zirconia powder using Amang zirconium oxychloride precursor.

Published: June 2024

The relationship between individuals and their thermal environment is pivotal not only for comfort but also for health and productivity. Thermal comfort, as defined by ASHRAE, reflects an individual's satisfaction with their ambient thermal conditions and can be gauged using the ASHRAE scale. In the past, traditional thermal comfort prediction models such as the Predicted Mean Vote (PMV) were used to evaluate thermal comfort. Nevertheless, the emergence of machine learning provides a more dynamic approach to predict thermal comfort of occupants. However, the subjective nature of thermal comfort introduces data ambiguities challenge which lead to the existence of outliers. Moreover, data imbalances within the dataset can cause the machine learning models to not learn the minority class effectively, resulting in the deterioration of the model. This research has developed an enhanced thermal comfort prediction model to predict the occupant’s thermal comfort by leveraging the outlier detection technique and synthetic data generator, particularly the Isolation Forest and SMOTE. The experiment showed that the proposed model is able to achieve an accuracy of 74.94%. This exhibited a slight improvement compared to the findings in prior research of using Random Forest prediction model.
A catalogue and redescription of type specimens of fireflies (Coleoptera, Lampyridae, Luciolinae) deposited in Naturalis Biodiversity Center, Leiden
Authors: Jusoh Wan F. A. , Ballantyne Lesley
Published: June 2024

Type specimens of flashing fireflies (Coleoptera, Lampyridae, Luciolinae) in the Naturalis Biodiversity Center, Leiden (RMNH) collection were documented. Specimens explicitly marked or indicated as types belonging to the lucioline fireflies were investigated with each specimen and its accompanying labels photographed, and its morphological characters analysed and compared with the original species description. The genitalia dissections of selected types enabled redescription and clarification of the taxonomic status of seven name-bearing type specimens. This study provides the first redescriptions of holotypes, designation of lectotypes for five species, and confirmation that two of these belong in the genus Luciola s. str. A lectotype and paralectotype were designated for two specimens of Luciola cerea Gorham, 1882 which is confirmed to belong to the genus Curtos Motschulsky, 1845. Atyphella testaceolineata Pic, 1939 was redescribed and figured based on the holotype (an incomplete specimen). We assigned Luciola laticollis Gorham, 1883 and Luciola nicollieri Bugnion, 1922 to Luciola sensu stricto and Luciola picea Gorham, 1882 to species inquirenda. The identity of Pteroptyx decolor Olivier, 1911 is finally confirmed as a close Indonesian relative of Pteroptyx valida Olivier,1909 and a lectotype is designated. In addition, we take the first opportunity to present pictures of the original holotype of Pygoluciola stylifer Wittmer, 1939. We also discuss the challenges taxonomists face in identifying specimens and how detailed dissections allow us to present descriptions of certain male features not previously addressed.

Published: June 2024

Digital transformation in public administration needs to be accompanied by more dynamic and intelligent strategies, which effect cultural change. Inspired by the business culture of startups, in 2021 the Brazilian government created the StartUp GOV.BR program to develop and accelerate the development of digital transformation projects within the Federal Government. This program aims to make digital transformation processes more proactive and flexible and generate more profitable operations. In this work, we investigated the perception of ICT practitioners (members of startups) about the program and the issues that surround it. Our goal was to identify relations, potentialities and restrictions of this program to contribute to outlining growth strategies, as well as the assets and capabilities needed to successfully transform digital public services in a startup-based environment. For this purpose, we conducted 23 focus groups with up to 12 people, totaling 175 participants. Then, we fully transcribed and qualitatively analyzed the data from each of the focus groups based on Grounded Theory. As a result, we developed maps of relationships between categories, along with narratives that help explain and understand the members’ perception of the StartUp GOV.BR program. We also listed 34 points for improvement and 62 actions to be taken to improve the program. The results achieved in this work can contribute to a research agenda of initiatives towards the Digital Transformation of public services in governments around the world combining innovative digital strategies based on the perspective of professionals.

Notes on its distribution, ecology and conservation status are included. The new species is known from an area with ca. 45 individuals, where it is restricted to the remote central windward region of Kaua‘i in open bogs and along open windy ridges. Suggested IUCN Red List status is CR (Critically Endangered). It differs from its Kaua‘i congeners by its longer petals and narrowly elliptic leaves with strongly undulate margins and tendril-like apex. Phylogenetic analysis using RADseq data supports the recognition of this new species.
Integrative taxonomy of a new giant deep-sea caudofoveate from South China Sea cold seeps
Authors: Chen Chong , Liu Xu , Gu Xinyu , Qiu Jian-Wen , Sun Jin
Published: June 2024

Caudofoveata is a class of worm-like molluscs (aplacophorans) that typically have an infaunal lifestyle, burrowing in soft bottoms in a wide range of marine habitats from shallow to deep waters. Here, we describe a very large new species of caudofoveate from South China Sea methane seeps growing up to 154 mm in length: Chaetoderma shenloongsp. nov. It is the first caudofoveate to be named from a chemosynthetic ecosystem and the first aplacophoran mollusc associated with seeps. Our new species stands out from other Pacific Chaetoderma species by its large size, a wide body relative to its length, a barely sclerotised radula, and the presence of isosceles-triangular sclerites. Phylogenetic reconstruction using the mitochondrial cytochrome c oxidase subunit I (COI) gene placed it within a paraphyletic clade comprising Chaetodermatidae and Limifossoridae, in line with a previous phylogenetic analysis. This also revealed that C. shenloongsp. nov. is conspecific with a Chaetoderma sp. whose whole genome was recently sequenced and assembled but remained undescribed until now. The most closely related species with an available COI sequence was C. felderi, the largest caudofoveate species recorded. Our discovery suggests caudofoveates may be present in other seeps globally but so far neglected; a potential example is C. felderi from the Gulf of Mexico, where seeps are abundant but whose exact habitat remains unclear.
Unveiling the impact of design methods on problem-solving performance in STEM education
Authors: Duran-Novoa Roberto , Torres Felipe
Published: June 2024

Problem-solving is at the core of engineering design, being fundamental for systematic innovation. During their education, students are taught numerous methods and tools, despite that literature shows debatable results regarding their real impact. Consequently, our study aims to quantify the relative impact of design methods on students' problem-solving performance and determine if this influence goes beyond their background and the problem's complexity. Utilising novelty, variety, and quality as criteria, we evaluated the work done by 144 students, solving two problems using three methods. Our results show a performance improvement of up to 46% when working with methods that guide solution development through design principles. The context and the student method preference did not affect their performance, while the increment in the problem's difficulty improved novelty and variety (15% and 11%) but reduced quality (34%). Surprisingly, the best-performance method was the least preferred, indicating the need of exploring the relationship between performance and actual use.Our results validate the work invested in teaching design methods, indicating the characteristics of the most efficient ones, beyond expert opinion. The structure of our study allows replication and could help future comparison of results.

Published: June 2024

Pedagogical renewal is a concept loaded with a historical-pedagogical trajectory linked to reflection, social justice, educational improvement, teacher commitment and the questioning of the educational model, with personalised education being a key aspect. The aim of this paper is to analyse how learning is personalised in primary education centres that promote processes of pedagogical renewal. A qualitative methodology is used, based on a case study. Two schools with a high intensity of pedagogical renewal were selected and in-depth interviews were conducted with the management team and teachers, focus groups with families and students, and participant observation. The information derived is analysed with the ATLAS.Ti 22 programme, after coding and categorisation. The results reveal a number of common elements and processes of personalisation of learning which are structured in three dimensions. In the first dimension, school characteristics, the following stand out: student autonomy, individualisation of learning and freedom of choice of learning pathways. As for the second dimension, educational project, the following elements stand out: flexible curricular organisation, active methodology where group work is a key element, organisation of timetables without previously established patterns, the role of accompanying teachers, student focus and active participation of families in daily school life. Finally, from the third dimension, inclusion, the following can be extracted: daily educational work where diversity is not a limitation, but a source of learning of great didactic value.

Published: June 2024

Computer engineering students should develop competences related to the contents of databases design and SQL queries. For this purpose, the recommendations on the convenience of changing the traditional teaching methodology to the flipped classroom are followed. In this article we present a quantitative study in which we compare the potential for the development of engineering students' competences in the design and use of databases of the flipped classroom methodology and the traditional teaching methodology. The results obtained in the evaluation of the subject in two different courses are compared. In the first course, traditional teaching methodology was used. In the second one, flipped classroom was used when its implementation had already been tried and tested. The results of the content blocks of database design and SQL queries are compared, according to the type of learning promoted. In this article we show evidence that the implementation of the flipped classroom teaching methodology provides different results depending on the learning promoted and on the specific contents in the subject of relational databases. The benefits of implementing the flipped classroom depend on the content and type of learning promoted. We have found evidence that they improve theoretical learning outcomes for database design and in the resolution of non-reproductive activities in the SQL queries block. No conclusive benefits are reported for students’ competency development for either of the two content blocks.
Resignifying pedagogical renewal today: Pedagogical benchmarks and singularities in secondary schools
Authors: De Castro-Calvo Ana , Carrete-Marín Núria , Simó-Gil Núria
Published: June 2024

Understanding what is meant by pedagogical renewal today, based on the transformative processes that are being carried out, poses a challenge, one that is even greater if the aim is to elucidate the pedagogical benchmarks and hallmarks of secondary schools. This article, which takes the form of a multiple case study, aims to bring to the fore those unique and defining elements of the selected schools, considered renewal schools, from five Spanish regions. During the fieldwork, semi-structured interviews, in-depth interviews and discussion groups were held with members of the management teams, teachers, families and students. The analysed results show that the elements highlighted by the schools linked to pedagogical renewal are unique features of them, with the school project being the tool used to construct the educational meaning of of its practices, aiming to ensure that these practices form a coherent whole with its discourse. Thus, for example, it highlights the central role of students in decision-making in their learning process or reflection with the teaching team in improving educational practice. It should be noted that they do not define themselves with the same term, and they add more current and recent pedagogical benchmarks to the classic ones. In short, this study seeks to provide a novel contribution to the study of contemporary pedagogical renewal, given the lack of such studies in secondary school education.
Classification of irreducible based modules over the complex representation ring of $ S_4 $
Authors: Wu Wenxia , Li Yunnan
Published: June 2024

The complex representation rings of finite groups are the fundamental class of fusion rings, categorified by the corresponding fusion categories of complex representations. The category of $ \mathbb{Z}_+ $-modules of finite rank over such a representation ring is also semisimple. In this paper, we classify the irreducible based modules of rank up to 5 over the complex representation ring $ r(S_4) $ of the symmetric group $ S_4 $. In total, 16 inequivalent irreducible based modules were obtained. In this process, the MATLAB program was used in order to obtain some representation matrices. Based on such a classification result, we further discuss the categorification of based modules over $ r(S_4) $ by module categories over the complex representation category $ {\rm Rep}(S_4) $ of $ S_4 $ arisen from projective representations of certain subgroups of $ S_4 $.
Financial assets against inflation: Capturing the hedging properties of gold, housing prices, and equities
Authors: Almeida Alejandro , Feria Julia , Golpe Antonio , Vides José Carlos
Published: June 2024

In this study, we employed a developed Fractional Cointegrating Vector Autoregressive (FCVAR) model to analyze the relationship between three different securities, i.e., housing prices, S&P500 stock prices and gold, and inflation rate, to determine the hedging properties of each type of asset against inflation shocks. Our analyses covered seven decades; ranging from January 1953 to January 2023. Our results suggested that housing prices and S&P500 performed partially against inflation and gold did not have hedging properties when attending to the full sample. Accounting for structural breaks, we discovered that these results changed. We found that housing prices and the S&P500 showed a superior hedging performance against inflation since the second regime. On the other hand, when we studied the behavior of gold, this security showed the inverse results, i.e., it showed no hedging performance in the second regime. Finally, these results were important for an optimal investment strategy, risk diversification, and monetarism.
Women, Children, and Enslaved People in the Portuguese Empire in Asia: Introduction
Authors: Vigas Rozely , Ehalt Rômulo
Published: June 2024

Recent studies on the Portuguese empire in Asia during the sixteenth to eighteenth centuries have highlighted the role and relationships of resistance and sociability among women, children, and enslaved individuals in that context. Often tied to institutional histories, these themes are traditionally understood through the framework provided by legal restrictions and privileges. The studies gathered here aim to emphasize the stories of women, children, and enslaved individuals, incorporating perspectives that shed light on narratives of resistance, tactics, negotiations, solidarities, and disputes led by these agents in the Portuguese empire in Asia. This text serves as the introduction to the special theme section on Women, Children, and Enslaved People in the Portuguese Empire in Asia, 16th-18th centuries, organized by the authors.
Kirishitan Women in Bondage Defying Persecution in Japan, 1625-1630
Authors: Ward Haruko Nawata
Published: June 2024

This article inspects cases of three Kirishitan (Christian) women servants in the Jesuit accounts of Shimabara, Japan, between 1625 and 1630, arguing that global and national changes resulted in the worsened enslaving conditions for servant-class women in Japan. The arrival of Portuguese traders and the Jesuit mission in the mid-sixteenth century, the Jesuits’ initial engagement in the slave trade, the ongoing civil wars, Japan’s invasion of Korea, the shogunate’s total ban of Christianity and Iberian commerce, and its consolidation of patriarchal structures by the 1640s accelerated the decline of women’s status. The sources, read in this context, show that under severe religious persecution, these women’s Kirishitan identity was crucial in their resistance to the multiple systems of oppression. This article is part of the special theme section on Women, Children, and Enslaved People in the Portuguese Empire in Asia, 16th-18th Centuries, guest-edited by Rozely Vigas and Rômulo Ehalt.
La construcción naval en la Galicia autonómica (1980-2023)
Authors: Gómez Alén José
Published: June 2024

A comienzos de los años ochenta la construcción naval en Galicia se encontraba en una profunda crisis que había comenzado a desarrollarse en el segundo lustro de la década anterior como consecuencia del alza de los precios del petróleo de los años 1973-74. En este trabajo se presentan los rasgos generales que han caracterizado el proceso de transformación del naval y sus repercusiones sociales para hacer frente a los efectos negativos de la crisis y a los problemas estructurales que arrastraba desde los años setenta. Condicionado por el inestable contexto político de la Transición y la consolidación de la democracia y por la posterior adaptación al marco jurídico y económico de la Comunidad Económica Europea, el sector se vería inmerso en una profunda reestructuración hasta finales del siglo XX. Los cambios en la titularidad de los astilleros y en su orientación productiva, así como las negativas consecuencias para el empleo que tradicionalmente había generado, originarían la intensa conflictividad sociolaboral que acompañaría el proceso de transformación del naval que alcanzaría cierta estabilidad a comienzos de la segunda década del siglo XXI.
Fédéralisme et nationalisme dans la Galice du Sexenio Revolucionario (1868-1874)
Authors: Cagiao y Conde Jorge
Published: June 2024

Mon objectif dans cet article est d’éclairer la problématique fédérale dans l’Espagne du XIXe siècle à la lumière de la littérature spécialisée dans le nationalisme. Il importe en ce sens d’accepter de voir les projets politiques de modernisation qui émergent à cette époque comme étant des versions différentes et concurrentes au sein du nationalisme espagnol. Le cas d’étude choisi est celui de la région de Galice pendant le Sexenio Revolucionario (1868-1874). Elle a ceci de particulier et d’intéressant que deux discours fédéralistes s’opposent : le discours majoritaire, qui est fondamentalement un discours nationaliste espagnol, et un discours minoritaire, qui semble intégrer l’héritage du premier galicianisme. L’analyse montre que l’idée de nation est fondamentale dans les deux cas.
A “Democrat” from the Start: Theobald Wolfe Tone, Emblematic Founder of Irish Republicanism, Anti-Monarchism, and the “Baneful Influence of England”
Authors: Kleinman Sylvie
Published: June 2024

Theobald Wolfe Tone (1763-98), an Irish radical and revolutionary remembered in collective memory as the founding father of Irish republicanism, left behind more writings than all his radical associates combined. A founder of the Society of United Irishmen in 1791, he helped drive their democratic campaign to end religious discriminations in Ireland through a total reform of electoral representation in the Irish parliament. Tone’s adolescence and national identity had been shaped during the American War of Independence, when Irish patriotic culture began to truly question the connection to Britain. When reform campaigns failed, Tone became a separatist first, and a democrat inspired by the French Revolution and Painite republicanism. He conspired with France for a military invasion of Ireland that would support a revolution and achieve independence. The Irish republic he imagined would be free from the “baneful influence of England”, as would be its national symbols which he reconfigured to subvert British dominion. Yet his political language, only recently analysed by scholars, is not driven nor dominated by anti-monarchism. This essay explores that paradox, and how Tone’s vocabulary, in his private writings included, inspired future generations, particularly during the 1916 Rising.

Published: June 2024

This paper examines the Management of Faecal Sludge and Septage in Urban Areas. Over 80% of all wastewater ends up going right away into ponds without treatment, which cannot be overlooked. In this context, FSSM alludes to a decentralised sludge and the septage management method that consists primarily of five components that comprise a faecal sludge value chain. In comparison to centralised sewerage systems, FSSM is the only affordable and sustainable technique that can be implemented quickly to make cities clean and healthy. Thus Ramdas, a fourth-class town, was chosen for study, and no systematic drainage facilities were built. Currently, the bulk of the town's houses rely on on-site sanitation systems such as septic tanks and pits to contain and partially treat generated black water. As a result, this town has been chosen to improve the existing sanitation conditions. It reveals that in the town 26 % of the household do not have septic tanks which are a main issue and 26% of the households are still practicing open defecation. Some houses have septic tanks, but are not well maintained and cleaned on time. Urgent attention is needed.

Steven Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) occur frequently with carbamazepine among the carriers of HLA-B*1502 allele. The study evaluated the clinical course and strength of this association in Sri Lanka.Twenty four consecutive patients with SJS/TEN from multiple dermatology centres were assessed for demographics, history and clinical course. Carbamazepine induced cases with a group of healthy control (10) were tested for HLA-B*1502 using multiplex PCR with sequence specific primers.The sample had a mean age of 41.6 years; female: male ratio of 3:1. Antiepileptics were the aetiological cause in 12 (50%), amongst 9 (37.5%) taken carbamazepine. The HLA-B*1502 allele was positive only in one patient but none in the control group (10). The mucosal involvement was common (95.8%).Carbamazepine is the commonest single therapeutic agent implicated in SJS/TEN, although the association with the HLA-B*1502 allele is weak in our sample. Early mucosal involvement is a reliable clinical sign useful for the diagnosis.

Pyoderma gangrenosum (PG) is a cutaneous condition characterised by the presence of a painful cutaneous ulcer showing rapid progression. PG is associated with a concomitant systemic disease in 50 to 70% of cases1.Herein, we report a 7-year-old patient, with a history of Burkitt lymphoma in remission, who presented with PG, and was treated successfully with corticosteroid and azathioprine.
The assessment of therapist responsiveness in psychotherapy research: a systematic review
Authors: Esposito Giovanna , Cuomo Francesco , Di Maro Angela , Passeggia Raffaella
Published: June 2024

Therapist responsiveness is an emerging construct in psychotherapy research that still lacks a clear definition and, consequently, a unique operationalization. Indeed, there is a great overlap between therapist responsiveness and other variables, such as attunement, flexibility, and empathy. This overlap inevitably hinders the assessment of the therapist’s responsiveness, although it is crucial for the effectiveness of the treatments. Therefore, the current systematic review aims at exploring the different methodologies of measurement and analysis of therapist responsiveness, including both direct and indirect instruments. The results confirmed difficulties and divergences in the operationalization of the construct, as shown by the great heterogeneity found in the choice and use of the tools. Furthermore, this review provides guidance for future research, clinical practice, and training of therapists.
A dumbbell-shaped peripheral obturator nerve sheath tumor
Authors: Sharma Aditya , Ansari Mumtaz Ahmad , Srivastava Vivek
Published: June 2024

Peripheral nerve sheath tumors are very rare to arise from the obturator nerve. As such, they are usually not considered one of the imaging diagnostic possibilities for a cystic-solid pelvic mass. The present case involves a 32-year-old man with a known pelvic mass who complained of increasing discomfort in his pelvic region along with swelling over his left inguinal area. The tumor was reported to exhibit mixed solid and cystic components after being tracked with serial imaging for 5 years.
Aprocitentan (TRYVIO)
Authors: Thomas Shalini
Published: June 2024

Aprocitentan (TRYVIO), is the first and only endothelin receptor antagonist for the treatment of high blood pressure not adequately controlled in combination with 3 combined antihypertensive class drugs. Aprocitentan is a dual endothelin receptor antagonist that inhibits the binding of ET-1 to both ETA and ETB receptors. Aprocitentan tablets are available as 12.5 mg orally once daily. It can be administered to subjects with mild and moderate hepatic impairment without the need for dose adjustment. The most frequently reported adverse reactions to during the 4-week double blind placebo-controlled treatment period (part 1) of the PRECISION study is edema and anaemia. Others include embryo-fetal toxicity, hepatotoxicity, fluid retention, hemoglobin decrease, decreased sperm counts. Aprocitentan is contraindicated in pregnancy and in patients who are hypersensitive to aprocitentan or any of its excipients.
A retrospective study about cancellation of elective surgeries in a tertiary care hospital
Authors: Raghavan Bhagyasree , Menon Ajoy , Velayudhan Ambily Kaiparambil
Published: June 2024

Introduction:

Operation theaters (OTs) are one among the core functionalities in a health care institution that require a considerable amount of 5 Ms—man, machine, money, material, and management. Any idle time or underutilization in the OT creates a huge loss of these resources and is also inconvenient to patients and those on the waiting list. Thus, a planned and well-conceived operational method has to be followed to reduce the cancelations of scheduled cases and to optimally utilize the OTs so that they become more efficient. This study has been done to understand the basic reasons for the cancelation of elective surgeries at a tertiary care hospital and to effectively tackle them by suggesting suitable solutions to overcome these challenges.

Objectives:

Primarily, to understand the reasons for the cancelation of surgeries in OTs, and secondarily, to put forward suggestions for optimal usage of OTs.

Materials and Methods:

This was a retrospective study, with Pareto analysis and root cause analysis (RCA) as the tools. Records were obtained from the Central Scheduling Department of the Hospital between January 2020 and November 2022 (35 months).

Results:

During the study period, 53,177 surgeries were performed in the main OTs. There were 2289 (4.3%) cancelations. Nearly 84% of canceled surgeries were canceled within 24 h. Cancelations were 63% in males and 37% in females. Seventy-nine percent were of Indian nationality, and the rest were of various nationalities.

Conclusion:

The reasons for the cancelation of elective surgeries were multifactorial. Controlling these, and thus preventing cancelations, is imperative in the effective functioning of the institution as a whole. We recommend thorough evaluation, early preanesthetic checkup (PAC) and well-planned scheduling without haste as some of the measures to reduce the chances of cancelation.
Morphometric Variations of Sphenoidal Air Sinuses in Human Cadavers
Authors: Syed Sadiqali Abbasali , Joshi Rajani Anil
Published: June 2024

Background:

The sphenoid sinuses are difficult to approach directly, so a transnasal approach is preferred. Due to the variable extent of pneumatization, there are variations in the size and shape of sphenoid ostium. These sinuses are related to many important structures, and they produce surface impressions on sinus walls. There are very few cadaveric studies that describe sphenoid sinuses morphometrically and their relation to nearby important structures. Hence, this study was undertaken to study the morphological variations of sphenoid sinuses; to measure the dimensions of the sphenoid sinuses; to classify the sphenoid sinuses and to study the variations of relation of important structures along the walls of the sphenoid sinuses.

Methodology:

The present study was performed on 25 formalin-fixed cadavers (50 hemisections). The morphometric anatomy of the sphenoid sinuses was studied by taking midline sagittal sections of the head, neck, and face regions in cadavers. Anteroposterior depth (infrasellar) and vertical height (presellar) of the sinus were measured. Based on the morphology of the sinus, they were grouped into conchal, presellar, sellar, and postsellar types. Surface impressions made by the carotid artery and optic nerve on the lateral wall of the sinus were observed.

Results:

The most common type of sphenoid sinuses was the sellar variety (68%), with conchal being the least common (0%). Most of the sinuses (88%) were divided by the intersinus septa. A round-shaped ostium of the sphenoid air sinus was found to be common (56%). Impressions of the internal carotid artery and optic nerve into the lateral wall of the sinus were prominent in highly pneumatized sphenoid sinuses.

Conclusions:

Variations observed are mainly due to variable pneumatization of the sphenoid bone. The degree of pneumatization will result in protrusion of the surrounding structures such as internal carotid artery and optic nerve into the sinus wall. The extent of pneumatization will determine the degree of protrusion of surrounding structures.
