Published: April 2021

Introduction

Frailty is a state of being vulnerable to adverse health outcomes such as falls, delirium, and disability in older people. Identifying frailty is important in a low-income setting to prevent it from progressing, reducing healthcare costs, increasing the chances of reversibility, and implementing effective interventions. The factors affecting frailty in older people living in old age homes could differ from those living in the community. This study was conducted to identify the factors associated with frailty in older people residing in old age homes and communities in Kathmandu Valley, Nepal.

Methods

This is a cross-sectional study conducted from April to June 2019 in three districts of Kathmandu Valley, Nepal. Data were collected from 193 older people residing in old age homes and 501 residing in communities aged 60 and above using convenience sampling. Frailty was measured using the Groningen Frailty Indicator. Data were collected via face-to-face interviews. Multiple linear regression analyses were used to examine the association between independent variables and frailty.

Results

Frailty was more prevalent among older people in old age homes (71.5%) compared to those in the community (56.3%). Older people who were satisfied with their living environment had lower frailty scores in both old age homes (β = -0.20, p<0.01) and the community (β = -0.15, p<0.001). Those who had self-rated unhealthy lifestyle had higher frailty scores in both old age homes (β = 0.45, p<0.001) and the community (β = 0.25, p<0.001). In the community, those over 80 years of age had higher frailty scores (β = 0.15, p<0.01) and those with higher education had lower scores (β = -0.13, p<0.05).

Conclusion

The living environment and lifestyle are key modifiable risk factors of frailty, both in old age homes and the community. The findings suggest a need for lifestyle modification and reforms in building standards, especially in old age homes, to promote age-friendly communities.

Editorial: Trafficking in Minors: Confronting complex realities, structural inequalities, and agency
Authors: Oude Breuil Brenda , Gerasimov Borislav
Published: April 2021

This Editorial introduces a Special Issue of the journal Anti-Trafficking Review of the topic of ‘Trafficking in Minors’. It argues that the urgency of the phenomena of child trafficking and related issues, such as child labour and child sexual exploitation, and the emotional responses they provoke, have often led to superficial and knee-jerk reactions that obscure the root causes of the problems and deflect attention and resources away from grounded, sustainable solutions. It presents a brief overview of the articles contained in the Special Issue and concludes that policy responses and practical interventions to address trafficking in minors need to have the best interest of the child in mind and address the underlying socio-economic and political root causes.

Authors: De Jesus Silva Themis , Carlos Soares Emerson , Navas Rafael
Published: April 2021

A apicultura é uma atividade capaz de causar impactos positivos nos aspectos social, ambiental e econômico. No Nordeste brasileiro é desenvolvida principalmente pela agricultura familiar, contribuindo para a renda das famílias e a permanência da população no campo, além de preservar o bioma caatinga. Nesse contexto, o objetivo desse trabalho foi avaliar o impacto da apicultura entre agricultores familiares do sertão de Alagoas. Foram realizadas entrevistas semiestruturadas com agricultores familiares. A produção de mel iniciou com o Projeto Arajuba, desenvolvido pelo MST e proporcionou suporte para o desenvolvimento de ações, como o início da produção, fornecimento de caixas, insumos, materiais e assistência técnica, além da formação e apoio à comercialização. A maioria dos agricultores entrevistados tem na produção de mel sua principal fonte de renda, principalmente pela limitação no acesso à água que restringe os plantios a estação chuvosa e tem o objetivo de autoconsumo e venda do excedente, associada a criação de pequenos animais. A renda é variável entre os entrevistados e é relacionada ao maior número de colmeias existentes. A falta de acesso às políticas públicas, em especial assistência técnica e crédito limitam o desenvolvimento e ampliação da atividade, bem como a adoção de novas tecnologias e inserção de novos agricultores, consolidando a atividade na região e promovendo o desenvolvimento rural, aliado a conservação do bioma. Mesmo com as limitações observadas, a apicultura mostra-se capaz de proporcionar renda para agricultura familiar e a inserção dos jovens.

Authors: Karnib Mohamad , Rhea Isaac , Elliott Robin , Chakravarty Saneka , Al-Kindi Sadeer G.
Published: April 2021

We report a rare case of benign metastasizing leiomyoma in the heart of a 45-year-old woman 2 years after a uterine leiomyoma had been discovered during hysterectomy. Computed tomograms at presentation showed a large mixed cystic mass in the pelvis and bilateral lung nodules suggestive of metastatic disease. A large cardiac mass, attached to the chordae of the tricuspid valve and later shown to be histopathologically consistent with uterine leiomyoma, was successfully resected through a right atriotomy. This case suggests that benign metastasizing leiomyoma should be considered in the differential diagnosis of right-sided cardiac tumors.

Published: April 2021

During the big data era, there is a continuous occurrence of developing the learning of imbalanced data gives a pathway for the research field along with data mining and machine learning concepts. In recent years, Big Data and Big Data Analytics having high eminence due to data exploration by many of the applications in real-time. Using machine learning will be a greater solution to solve the difficulties that occur when we learn the imbalanced data. Many real-world applications have to predict the solutions for highly imbalanced datasets with the imbalanced target variable. In most of the cases, the target variable assigns or having the least occurrences of the target values due to the sort of imbalances associated with things or events strongly applicable for the users who avail the solutions (for example, results of stock changes, fraud finding, network security, etc.). The expansion of the availability of data due to the rise of big data from the network systems such as security, internet transactions, finance manipulations, surveillance of CCTV or other devices makes the chance to the critical study of insufficient knowledge from the imbalance data when supporting the decision making processes. The data imbalance occurrence is a challenge to the research field. In recent trends, there is more data level and an algorithm level method is being upgraded constantly and leads to develop a new hybrid framework to solve this problem in classification. Classifying the imbalanced data is a challenging task in the field of big data analytics. This study mainly concentrates on the problem existing in most cases of real-world applications as an imbalance occurs in the data. This difficulty present due to the data distribution with skewed nature. We have analyses the data imbalance and find the solution. This paper concentrates mainly on finding a better solution to this nature of the problem to be solved with the proposed framework using a hybrid ensemble classifier based on the Binary Cross-Entropy method as loss function along with the Gradient Boost Algorithm.
Resolving Interoperability Issues of Date with Null Value and Collection of Complex Data Types by Using JADE-WSIG Framework
Authors: Chawla Jaspreet , Ahlawat Anil Kr.
Published: April 2021

In today’s world, the internet and distributed computing make things so convenient that web services can be easily built and fetch from any platform. Web services are loosely coupled, interoperable, and heterogeneous hence they help to connect web applications of different languages. Interoperability is the major factor while transferring web services from one platform to another platform.WS-I basic profile 1.0/1.1 organization provides guidelines to achieve interoperability of web services at a basic level but still, issues arise at a complex level. In this paper, we have discussed and shown the result of two interoperability issues i.e. Date with Null value and Collection of Complex data types of web services using JAVA and.NET environment. In the first issue.NET treat NULL as a value type and JAVA treats NULL as reference type in date-time data type. So, whenever a JAVA client fetches a web service built in.NET it will show a parsable error. In the second issue, a web service data structure contains elements of any type. Whenever, a web service built with the ‘ArrayOfAnyType’ data structure, it can be easily mapped to a.NET client but not to JAVA client. Hence, a data type mismatch issue arises here. To resolve these inter-platform issues, we have used JADE-WSIG as middleware between web services and agent-technology.

Authors: Sujatha G. , Raj Dr. Jeberson Retna
Published: April 2021

Data storage is one of the significant cloud services available to the cloud users. Since the magnitude of information outsourced grows extremely high, there is a need of implementing data deduplication technique in the cloud storage space for efficient utilization. The cloud storage space supports all kind of digital data like text, audio, video and image. In the hash-based deduplication system, cryptographic hash value should be calculated for all data irrespective of its type and stored in the memory for future reference. Using these hash value only, duplicate copies can be identified. The problem in this existing scenario is size of the hash table. To find a duplicate copy, all the hash values should be checked in the worst case irrespective of its data type. At the same time, all kind of digital data does not suit with same structure of hash table. In this study we proposed an approach to have multiple hash tables for different digital data. By having dedicated hash table for each digital data type will improve the searching time of duplicate data.

Authors: Hamid Nur , Savitri Fania Mutiara , Perwita Atika Dyah , ab Wah , Purandina Yoga
Published: April 2021

The concept of entrepreneurship is an important factor for increasing economic growth in Indonesia. Moslempreneur is an actor in entrepreneurship, who has and shows an identity with a distinctive personality and characteristics as a Moslem, who is able to carry out Islamic business ethics. Business competition in the global era demands a competitive advantage. The phenomenon that arose from the formation of a university graduate’s entrepreneurship is laymen. The construction of entrepreneurship from moslem workers who have a professional background and feel bored in the organization can increase the amount of entrepreneur effectively. This study used a behavioral and organizational approach in forming professional moslempreneurs, so this study examined individual, organization, market factor, and professional skills that affect moslempreneur intention and behavior by using the Structural Equation Model (SEM) in executing data analysis on this quantitative research. Sampling was collected by a purposive snowball sampling method on 108 moslempreneur respondents in Indonesia who have a professional background. The results showed that 1) entrepreneurship intention reflected through individual factors, market factor, and professional skill; 2) organizational factors affect professional skill; 3) entrepreneurship intention affects entrepreneurship behavior; 4) the contextual elements (entrepreneurial instruments) do not moderate the relationship between the entrepreneurship intention to entrepreneurship behavior. The managerial implication suggests potential experienced moslem workers who are still in the organization and intend to be entrepreneurs can be moslempreneurs without any hesitation in making entrepreneurial decisions. This research finding revealed new mini theory named a "Signaling Moslempreneurship".

Given COVID19 has caused many institutions to consider a similar shift the UNE exams team present an account of this project and advice for other institutions on this transition.
Transforming assessment – Critical reflections around resolving tensions between assessment for learning and of learning
Authors: Cerimagic Sabina , Khanna Priya
Published: April 2021

Current assessment and progression policies and practices in higher education are largely dominated by dichotomy between formative and summative assessments. Given assessments are major drivers of learning, such as dichotomous assessment systems which promote the learning that can only be tested via summative assessments and falls short in fostering complex graduate attributes - such as interdisciplinary competencies. Medical programs, across the globe are now embracing emerging concepts such as programmatic assessment that allows the assessments to serve ‘for, of and as’ learning. Given the most challenging curricular reform in any field, including Business is reforming assessments, this paper critically reflects on how emerging concepts such as programmatic assessment are promising in resolving the tensions created by dichotomy of assessment for vs as learning. The reflections are based on rapid scoping review of programmatic assessment in Medical education, as well as authors’ familiarity with implementation of programmatic assessment in the Sydney Medical School renewed curriculum. There are many lessons that can be learned and carried over from the University of Sydney Medical curriculum to the Business education space.
Revisiting the Intelligent Book: Towards seamless intelligent content and continuously deployed courses
Authors: Billingsley William
Published: April 2021

In the early 2000s, colleagues and I developed The Intelligent Book – a suite of technologies for adaptive materials, that let students work with smart graphical exercises as if the AI was their partner rather than their marker. We envisaged a future where online content would be brimming with interactive models, lettings students explore and tinker with problems alongside AI that would guide students in their thinking. The browsers of the day were technically limited, but since then, the technological landscape of the web has transformed. Meanwhile, online education (especially during the Covid-19 pandemic) has grown the need for interactive materials that “understand what they teach” and can make explanations explorable and “proddable”. In online education, physical group activities (e.g., programming robots) are not available to us, and we see a growing need for digital experiences and models to replace the responsiveness that comes from tangible interaction with a device or experiment. Over the last two years, I have begun revisiting the ideas of the Intelligent Book for the modern technology landscape. This paper gives an early overview of the project, working once again towards infrastructure for self-publishable courses that can be full to overflowing with proddable and explorable models.

Adaptation to driver-assistance systems depending on experience
Authors: Ucińska Monika
Published: April 2021

Many tasks that until recently could only be performed by humans are now entrusted to machines. Automation plays an increasingly important role in many areas of life, and its special role is observed in broadly understood transport, affecting the mobility, behaviour, and safety of drivers. Faced with the threat of a large number of accidents, deaths, and injuries, vehicles equipped with driver-assistance systems, the so-called ADAS (advanced driver-assistance system), are a significant support for the driver in reacting to the unexpected situations. The studies conducted so far indicate that the experience of using these systems may increase not only the comfort but most of all the safety of road users. In Poland, such analyses are still a challenge. The aim of the study designed by scientists from the Motor Transport Institute was to analyse the impact of the experience in using a vehicle equipped with systems on the speedy adaptation to the use of new driver-assistance systems. The adaptation process for the use of three systems was taken into account: adaptive cruise control, blind spot detection system, and lane keeping assistant. The research was carried out in real traffic. Particular attention was paid to the reactions of people who have no experience with the use of driver-assistance systems in vehicles, compared to those who have used these systems before. Proprietary questionnaires on the drivers’ feelings were used for the analyses. As expected, the analyses showed that experience with driver-assistance systems is an important factor influencing the speed of adaptation and the sense of comfort in using the systems.
Analysis of effect of modification of silica and carbon black co-filled rubber composite on mechanical properties
Authors: Wang Xuefei , Wu Lingling , Yu Haiwen , Xiao Tongliang , Li Huaming , Yang Jun
Published: April 2021

Silica and carbon black (CB) co-filled rubber composite was widely used for tire tread and other rubber products because of combined advantages of binary fillers, such as low hysteresis, good abrasion resistance, and reinforcement. Numerous studies have been focused on the filler–rubber interaction with the aim of obtaining optimum performances. To investigate the effect of modification on properties of rubber composite, modified silica and CB co-filled rubber composite was prepared with a multi-functional silane coupling agent, 2-aminoethyl-2-(3-triethoxysilylpropyl)aminoethyl disulfide (ATD). Such modification significantly enhanced the filler–rubber interaction and improved the filler dispersion. For the modified composites, the state of cure, hardness, tensile strength before and after aging, stress at 300% elongation, tear strength, abrasion resistance, rebound resilience, compression set, temperature rise, and the value of dynamic loss coefficient ranging from −20°C to 80°C were significantly improved, especially with low ATD dosage (3.0 phr). This modification provides an effective route to prepare silica and CB co-filled rubber composites with improved mechanical properties and dynamic mechanical properties.

Published: April 2021

Advanced materials were used and are being implemented in structural, mechanical, and high-end applications. Contemporary materials are used and being implemented in structural, mechanical, and high-end applications. Composites have several major capabilities, some of them being able to resist fatigue, corrosion-resistance, and production of lightweight components with almost no compromise to the reliability, etc. Nanocomposites are a branch of materials within composites, known for their greater mechanical properties than regular composite materials. The use of nanocomposites in the aerospace industry currently faces a research gap, mainly identifying the future scope for application. Most successes in the aerospace industry are because of the use of suitable nanocomposites. This review article highlights the various nanocomposite materials and their properties, manufacturing methods, and their application, with key emphasis on exploiting their advanced and immense mechanical properties in the aerospace industry. Aerospace structures have used around 120,000 materials; herein, nanocomposites such as MgB2, multi-walled carbon nanotubes, and acrylonitrile butadiene styrene/montmorillonite nanocomposites are discussed, and these highlight properties such as mechanical strength, durability, flame retardancy, chemical resistance, and thermal stability in the aerospace application for lightweight spacecraft structures, coatings against the harsh climate of the space environment, and development of microelectronic subsystems.

Published: April 2021

This article endeavors to present the impact of conducting robot-assisted music-based intervention sessions for children with low-functioning (LF) autism. To this end, a drum/xylophone playing robot is used to teach basic concepts of how to play the instruments to four participants with LF autism during nine educational sessions. The main findings of this study are compared to similar studies conducted with children with high-functioning autism. Our main findings indicated that the stereotyped behaviors of all the subjects decreased during the course of the program with an approximate large Cohen’s d effect size. Moreover, the children showed some improvement in imitation, joint attention, and social skills from the Pre-Test to Post-Test. In addition, regarding music education, we indicated that while the children could not pass a test on the music notes or reading music phrases items because of their cognitive deficits, they showed acceptable improvements (with a large Cohen’s d effect size) in the Stambak Rhythm Reproduction Test, which means that some rhythm learning occurred for the LF participants. In addition, we indicated that parenting stress levels decreased during the program. This study presents some potential possibilities of performing robot-assisted interventions for children with LF autism.

Authors: Hacioglu Mayram , Oyardi Ozlem , Kirinti Alpcan
Published: April 2021

Candida spp. can form biofilms on mucosal surfaces and epithelial cells as well as on devices implanted in the body such as catheters and dentures, which are thought to underlie the most recalcitrant infections. It was aimed to show antifungal and antibiofilm activities of oregano oil (Origanum onites). The antifungal activities of some essential oils were investigated against C. spp. and among them, oregano oil was found to be the most effective oil and further biofilm studies were conducted with it. Oregano oil inhibited biofilm adhesion and formation of C. spp. and mature biofilms and also displayed the ability to reduce biofilm formation when they were allowed to form on surfaces previously coated with oil (up to 50% inhibition rates). In addition, oregano oil was found to be effective against dual biofilms of Candida albicans + Staphyloccocus aureus at different concentrations. This study suggests that O. onites essential oil has useful antibiofilm effects against C. spp. The inhibitory effects of O. onites essential oil, against C. spp., were demonstrated for the first time. It also had antifungal effect on biofilm formation and established biofilm even at MIC level.
A Hollow Cylinder Torsional Shear Device to Explore Behavior of Soils Subjected to Complex Rotation of Principal Stresses
Authors: Prasanna R. , Sivathayalan S.
Published: April 2021

A hollow cylinder torsional shear device that is modified to simulate more generalized earthquake loading, involving simultaneous compression and shear wave loading in situ, is presented. The nature and degree of stress rotation due to coupled action of compression waves and shear waves are discussed, and illustrative experiments conducted to simulate different loading scenarios in the laboratory are presented. The stress rotation due to this coupled loading is significantly influenced by the initial consolidation stress state and shearing parameters such as the ratio between shear stress and normal stress increments (ΔS/ΔN) and the phase shift (ϕ) between the waves. The representative (ΔS/ΔN) ratios were obtained from the numerical simulations and used in hollow cylinder torsional shear apparatus to investigate the cyclic response of Fraser River sand under the simultaneous action of normal and shear stresses. Typical cyclic test results demonstrating the capability of a hollow cylinder torsional shear apparatus commissioned at Carleton University in following complicated cyclic loading paths are presented in this paper. It is noted that loading under such nonconventional stress paths, such as elliptical and circular paths, could be initiated along different pathways. Cyclic test results along these pathways demonstrate that soil response is dependent on the overall path including the initial stress state. Test results also highlighted the significance of stress rotation and cyclic stress paths in affecting the liquefaction susceptibility of sands.
Sometimes It’s Necessary to Break a Few Rules

In October of 2020, the University of Arizona’s College of Social and Behavioral Sciences hosted a lecture series called Womanpower. The final lecture was an interview between Michelle Téllez and Yalitza Aparicio—an Indigenous woman, actress, and activist. This interview transcript (originally conducted in Spanish) discusses Aparicio’s childhood, her experiences with discrimination, her role in the groundbreaking film Roma, and her activism on behalf of domestic workers and Indigenous peoples. In this interview, Téllez highlights issues of Indigenous rights, recognizing how Aparicio’s platform can bring visibility to the O’odham land defenders fighting for their sacred lands today, but also to Indigenous peoples fighting for their territories in Mexico, as alluded to in Roma. Téllez wanted to recognize the power that is ever-present in the bodies and minds of women workers who create possibilities despite their circumstances, and who maneuver between space and place, languages and cultures as they center homes, both their own and others. She points us to Aparicio’s role as a domestic worker to remind us of the silent but ever-present power of women. Téllez connects the interview with her own research and personal experiences growing up along the U.S./Mexico border in the cities of San Diego/Tijuana – where she was witness to the racial, gendered, and classed dynamics of power and exclusion.
The Myanmar-Rohingya Crisis, Civilian Protection, and the Dilemma of the Responsibility to Protect Norm Institutionalization
Authors: Erameh Nicholas Idris , Ojakorotu Victor
Published: April 2021

Existing studies on the Myanmar-Rohingyan crisis have explored the contending issues from a narrow perspective. This underscores the need for broader engagement by interrogating the veracity of the claims of mass atrocities against the Rohingyans, nonauthorization of the Responsibility to Protect (RtoP), and implications for consolidating and internalizing the RtoP norm. This study argues that, while the acts of genocide, crimes against humanity, war crimes, and ethnic cleansing against the Rohingyans satisfies four of the crimes upon which RtoP can be authorized, its nonauthorization suggests that in spite of its commitment to “Never Again,” the international community is yet to come to terms with issues bordering on mass atrocity and civilian protection. This inaction amidst widespread atrocities against the Rohingyans explains why the RtoP is not only contested, but also risks the chances of further nonutilization and institutionalization. Thus, the possibility that the RtoP would remain valuable depends on how the international criminal court and the global community prosecute those culpable of atrocities against the Rohingyans, adopt a clear rule of establishing when mass atrocity has been perpetuated and demand RtoP intervention, and ensure that these interventions are guided by the principle of Jus in Bellum and Jus ad Bello.
Rare presentation of collapse and cardiomyopathy in phaeochromocytoma
Authors: Singh Rajiv , Mohandas Cynthia
Published: April 2021

A phaeochromocytoma is a rare neuroendocrine tumour derived from the chromaffin cells of the adrenal medulla. Tumours can produce excessive amounts of catecholamines. The presenting symptoms can vary but often include the classic triad of episodic headaches, sweating and palpitations. Due to catecholamine excess, patients can develop cardiomyopathy. Bradycardia and collapse could be the result of sinus node dysfunction or transient dysregulation of the autonomic nervous system. Patients with co-existing diabetes can have improvement or resolution of their diabetes after successful adrenalectomy. We report a case of an 87-year-old lady who initially presented with sweating, palpitations and collapse, resulting in a permanent pacemaker insertion. She was later found to have a large adrenal incidentaloma with subsequent markedly elevated plasma metanephrine levels. She later presented with chest pain and in acute pulmonary oedema with normal coronary arteries visualised on coronary angiogram. After surgical excision of her phaeochromocytoma, her diabetes resolved with her HbA1c improving from 68 to 46 mmol/mol, with no further requirement for diabetic medications. Her pulmonary oedema improved with no ongoing need for diuretic therapy. This case highlights that phaeochromocytomas can affect multiple systems and there should be a very high index of suspicion in patients presenting with sweating, palpitations, hypertension and a history of diabetes and even in those with collapse.

Learning points

There should be a high index of suspicion for phaeochromocytomas in patients with palpitations, diaphoresis, anxiety, hypertension and diabetes.

Rarely phaeochromocytomas can present as bradycardia and collapse due to sinus node dysfunction or transient autonomic dysregulation and that should be considered in older patients.

Catecholamine cardiomyopathy can occur in phaeochromocytoma with potential resolution after successful surgical excision.

Diabetes can resolve after successful surgical treatment of a phaeochromocytoma.

Published: April 2021

La presente investigación tiene por cometido proponer una alternativa a la autoevaluación de los estilos de enseñanza en educación superior. Para lograr lo anterior se realiza una revisión sobre la autoevaluación de los docentes como elemento de evaluación de la docencia, así como sus principales instrumentos. El proyecto opta por la evaluación de los estilos de enseñanza que son analizados y definidos especificando dos perspectivas para su evaluación: funcionalista y pedagógica reflexiva. Finalmente se discuten los retos del análisis psicométrico de este tipo de instrumentos y de la pertinencia del uso de coeficientes de consistencia como el Alfa de Cronbach. Con base en lo anterior, se desarrolla un instrumento en 6 fases que contempla la exploración y posterior definición de estilos de enseñanza que emergen de los datos y que no son dicotómicos ni conceptualizados desde una lógica de eficacia docente. Al calcular la consistencia interna se encuentra como alternativa al Alfa de Cronbach el coeficiente Omega. Se plantea la posibilidad de discutir la estabilidad de los estilos de enseñanza encontrados.

Published: April 2021

En el contexto académico actual el aprendizaje por competencias implica la renovación a metodologías más activas que se acerquen a la realidad profesional, y cambios en la forma de evaluar. El presente estudio, realizado durante los cursos 2017/2018 y 2018/2019, trata de valorar la eficacia de una experiencia de innovación docente en la adquisición de competencias específicas, el rendimiento académico y la autoevaluación de 44 estudiantes del Máster de Psicología General Sanitaria (MPGS). En concreto, el alumnado participó en el diseño y desarrollo de un programa de entrenamiento de habilidades sociales (HHSS) para pacientes, actuando como terapeuta-coterapeuta (participación directa), y/u observador-registrador (participación indirecta). Asimismo, se incorporó a la experiencia a dos alumnas invidentes para determinar qué tipo de adaptaciones se podrían llevar a cabo. Los resultados muestran que el alumnado ha adquirido las competencias específicas evaluadas y se ha producido una mejora del rendimiento académico, así como de la autoevaluación global y por competencias. A este respecto, no se encontraron diferencias entre el alumnado en función de su participación. Por otro lado, se hallaron diferencias entre la evaluación y autoevaluación, aunque con un tamaño del efecto bajo al concluir el programa. Finalmente, se discuten los hallazgos y las adaptaciones curriculares.

The penetration of foreign objects is one of the leading causes of maxillofacial infection following trauma. Failure to detect such objects at initial stages can lead to complications like abscess formation, cellulitis, or space infections. Detection is even more complicated if the patient presents to the maxillofacial center after a delay of days or weeks following trauma. Sole reliance on radiographs or CT can be inconclusive as most of these objects are radiolucent and can be difficult to detect even by the experienced radiologists. We report the case of a patient who had an unwitnessed trauma and presented to our center 7 days after the incident, with signs of buccal space infection. Failure to detect the embedded intra-oral wooden object at an earlier stage led to the propagation of infection to superficial temporal space. The management strategy and pitfalls associated with conventional imaging in detecting wooden object are discussed.
