Brazil-Inspired Vertical Hive Technology for the Philippine Version
Authors: Grajo Leo
Published: December 2022

The Bicol Region is the birthplace of meliponiculture in the Philippines using the native stingless bee species, Tetragonula biroi Friese. Mr. Rodolfo Palconitin of Guinobatan, Albay, started the traditional method of stingless beekeeping using indigenous material, the coconut shell, which he called bao tech or coconut shell technology. It is a form of natural hive duplication wherein coconut shell halves are gradually mounted on top of each other as the colony grows. In this technology, hive product harvesting and colony splitting are done when the stingless bees have filled up the coconut shell halves. Inspired by the visit to the University of Los Baños (UPLB) Bee Program in 2010, the Grajo's Farm started using bao technology with several experimental hives upon return to home.
Morphometric Analysis in Stingless Bee (Apidae meliponini) Diversity
Authors: Ab Hamid Suhaila
Published: December 2022

Insects occur in large numbers. Therefore, it is important to have a system to identify the different species of insects. Traditional morphological identification of insects requires an experienced entomologist while molecular techniques require laboratory expertise and involve substantial costs. Due to that, there has been a dramatic increase of studies using morphometric analysis in understanding the systematics, taxonomy, and diversity of stingless bees. Morphometric analysis is a powerful tool as it is effective with minimum technical experience. It is a simple technique because of the current availability of cheap computer technology equipped with software, and at the same time, this method preserves the physical integrity of the shape measured. Morphometric analysis makes it credible to recognise morphological disparity and lead ways to explore the causes, both within and between, the stingless bee populations.
Deep Learning-Enabled Edge Computing and IoT
Authors: Nallathambi Amuthan , Nova Kannan
Published: December 2022

Deep learning is a new approach to artificial intelligence that enables edge-computing systems to learn from data and take decisions without human intervention. Edge computing is a technique for coping with the increasing demand for streaming data. This is especially important in the case of applications that involve computationally intensive tasks such as driverless cars, autonomous drones, and smart cities. Edge computing is the provision of computing, big data analytics, and storage in such a way that the data comes to the processing power and not vice versa. It relies on a decentralized approach where computational resources are provided at the edge of networks. Edge computing is an emerging field that's getting attention from many vendors and researchers. The data generated by IoT devices is usually too large and complex for cloud-based storage and processing. That's why edge computing can handle data at the source of generation in real time, which speeds up the process of decision making.
Distributed Deep Learning for IoT
Authors: Nallathambi Amuthan , Sivakumar N.  , Velrajkumar P.
Published: December 2022

Distributed deep learning is a type of machine learning that uses neural networks to learn and make predictions at scale. This is achieved by having many different computer systems that are connected via the internet. This allows for more parallel processing and faster results. In addition, when it comes to IoT, this type of technology can be used in conjunction with sensors and other devices to create more accurate predictions about the environment around us. Distributed deep learning can be used in many ways with the IoT because it can be applied to various aspects of IoT data processing, such as image recognition, speech recognition, natural language processing (NLP), or anomaly detection. The neural net is the most computationally intensive component of the system, and it requires a significant amount of energy. To make this system more cost-effective, there are two ways to lower the number of memory accesses: by reducing the size of images (so precision decreases), or by increasing network bandwidth so that there are fewer loop iterations required for each memory access.

Published: December 2022

The potential growth of internet of things (IoT) brings people and things together to handle daily tasks in a smart way. The major advancement the IoT offers is quality data sensing and faster data analytics through hurdle-free communication. The increasing number of devices and heterogeneous network natures unwrap more challenges in terms of quality of service. Currently, the deep learning algorithm explores different dimensions of service quality gradually in IoT scenarios. In order to effectively handle a dynamic IoT environment, it is essential that the design of IoT must be supplemented with an intelligent agent for providing effective QoS. The traditional methods are not capable of utilizing historical data to find insights into service quality improvement. In this chapter, a comprehensive analysis of deep learning techniques for improving QoS of the internet of things is carried out. Deep learning solutions for improving QoS and the challenges involved are compared. The deep reinforcement learning (DRL) for improving QoS in IoT and its evaluation technique are also explored.

Published: December 2022

We can perceive, analyse, control, and optimise the conventional physical systems thanks to pervasive IoT applications. Numerous IoT apps have recently had security breaches, which suggests that IoT applications could endanger physical systems. Numerous security issues in IoT applications are mostly caused by two factors: severe resource restrictions and inadequate security architecture. Edge-based security designs for IoT applications are still in their infancy, despite some research efforts in this direction. In addition to providing an in-depth analysis of current edge-based IoT security options, this study seeks to provide inspiration for new edge-based IoT security designs. A significant deal of progress in artificial intelligence (AI) opens up a number of potential avenues for addressing the security challenges in the setting that privacy preservation and security have become essential issues for EC. This chapter addresses issues with edge computing-based internet of things at the computation and security levels.

Sustainable Engagement in Open and Distance Learning With Play and Games in Virtual Reality
Authors: Mystakidis Stylianos
Published: December 2022

Open and distance learning became a global household term as it came to the forefront of education and work due to the proliferation of remote emergency teaching imposed by the pandemic's social distancing. Virtual reality (VR) is a technology that can transform distance education by overcoming the shortcomings of 2D web-based systems such as learning management systems and web-conferencing platforms. VR-powered teaching can support educators in implementing game-based methods, such as playful design, gamification, and serious games (e.g., educational escape rooms that promote intrinsic motivation towards sustainable engagement for durable, deeper learning). However, a transition from 2D to 3D teaching in the context of the Metaverse is not straightforward or intuitive as it requires a mental and paradigm shift. This chapter presents practical examples of applications and recommendations for practitioners.

Published: December 2022

Immersion in virtual worlds presented opportunities for simulating the qualities valued in face-to-face classes with the flexibility afforded by online learning. Immersive learning engaged educators, curriculum designers, campuses, conferences, and educational community groups to devise new ways to collaborate and engage learners. Dreaming of opportunities that were not possible in the online classroom, educators saw the potential of building communities in virtual worlds. They gathered to share their and to employ novel approaches to address educational challenges. This chapter explores the phenomenon of selfhood and society integral to the development of a vibrant educational community. At the heart of virtual world education is an ecosystem of institutions, groups, and conferences comprised of the early adopters and pioneers who stimulated their imagination and pooled their resources to encourage and strengthen the community and cast their eye to the future.
Avatars for Clinical Assessment
Authors: Triberti Stefano , Sebri Valeria , Savioni Lucrezia , Gorini Alessandra , Pravettoni Gabriella
Published: December 2022

Avatars are an important feature of digital environments. Existing both in social networks and webchats (usually as static images) and in single-player and online video games (as dynamic characters, often humanoid), avatars are meant to represent users' action and communication within digital environments. Research has shown that, when they are customized by users, avatars are not created “randomly,” rather they maintain some kind of relationship with users' actual self-representation and identity. However, more recent studies showed that users may have multiple digital representations: the same person could create multiple avatars depending on which facet of the self is primed by an experimental manipulation, or on which aims they have to pursue in the given virtual environments (e.g., to seduce, to play, to work). With this background, this contribution explores the possibility to use customized avatars within psychological assessment, as adjunctive assessment tools useful to get information on patients' self-representation(s) and communicative intentions.

Authors: Thomas Michael , Cinganotto Letizia
Published: December 2022

This chapter explores data form two online language teacher training courses aimed at providing participants with the skills to create and use games in 3D immersive environments. Arising from a two-year project which explored how game-based learning and virtual learning environments can be used as digital tools to develop collaborative and creative learning environments, two training courses were developed to support teachers to use two immersive environments (Minecraft and OpenSim). The first course was self-directed and the second was moderated by facilitators. Both courses provided a variety of games and resources for students and teachers in different languages (English, German, Italian, and Turkish). This chapter explores feedback from the teacher participants on both courses arising from a questionnaire and interviews with teachers and provides recommendations about the technical and pedagogical support required to develop immersive worlds and games for language learning.

Authors: Hassan Mohamed E. , El Bhery Mohamed B.
Published: December 2022

Ancient textiles can suffer from aging, deterioration, and events that deeply influence their original beauty and ethnological and economic value. The environmental conditions (temperature, humidity, light exposure, microbial contamination) that artifacts encounter during their lifetime strongly influence the value of the item, including those in the exhibition rooms of the museum, which are essential for proper preservation. Therefore, it was necessary to find an effective and safe method to clean these important archaeological materials. This method depends on enzymes, especially in their immobilized form, so that this method is economical, as the immobilized enzyme can be reused several consecutive times.

Authors: Arifin Nadirah , Yet Zaida Rahayu , Abdul Rahim Mohd Zulkhairi
Published: December 2022

This research is about the fabrication and properties study of the alginate bio-composites film for potential use in food sensing applications. A response surface methodology (RSM) was employed to optimize the concentration of sodium alginate (1 to 5% w/v), glycerol (0.4 to 0.8% w/v), and maltodextrin (0.4 to 0.8% w/v) as a function of the tensile strength (TS) and elongation at break (EB) and toughness (T) of the biofilms. The coefficientdetermination (R2) result obtained for TS against alginate, glycerol and maltodextrin is 81.05%, while for EB and T are 32.07% and 64.70% respectively. It showed that the addition of sodium alginate, glycerol and maltodextrin at different concentrations had significantly affected the TS but no effect on EB and T was observed. The optimization study of the film produces two conditions which are conditions 1 and 2. The optimum conditions parameter for condition 1 is a film with 3.0% alginate concentration, 1.0g/g of glycerol content, and 1.50g/g of maltodextrin content while condition 2 was 1.0% of alginate concentration, 1.0g/g of glycerol content and 0.0g/g maltodextrin content. The values of the TS obtained at the optimized condition were 4.75 MPa and 22.99 MPa which is lower than the predicted value of condition 1 (7.0 MPa) or the maximized TS at condition 2 respectively. The thickness value of edible films in this study had an average of 0.54 mm which was higher than the maximum standard thickness of edible films according to the Japanese Industrial Standard (JIS) which is 0.25 mm. Water Vapour Permeability (WVTR) study indicated that all alginate films in this study had a value higher than the JIS 1975 standard of WVTR for edible films which is at a maximum of 10 g/m2/24 hours. The natural colour from Clitoria Ternatea was successfully immobilized into the alginate-based film and the film become dark purple. Based on the result obtained, prediction equations for responses studied are adequate to describe the experimental data on tensile strength, elongation at break, and toughness. However, further modifications are necessary for improvements in mechanical characteristics in the future.
Twelve roles of a medical teacher: how this model can benefit physicians in Sri Lanka
Authors: Ariyananda P. L.
Published: December 2022

Although the main duty of physician is to heal the patient, they need to realise that they have to serve another important responsibility, as clinicianeducators. In many non-industrialised countries, physicians devote most of their time and energy to patient-care and pay little attention to their role as teachers. This has been overcome to some extent in industrialised countries by maintenance of teaching portfolios and regular performance appraisals. In 2000, Harden and Crosby suggested that a good teacher is more than a lecturer and has six main roles: information provider; role model; facilitator; assessor; planner; resource developer. Each of these six main roles has two subsidiary roles resulting in a total of 12 roles. Although this paper was published more than 20 years ago, it addresses some fundamental aspects of teaching, learning and assessment. Therefore, it can be adopted as a framework to develop teaching portfolios of physicians, even in today’s context, and is applicable in enhancing the role of teaching by physicians in Sri Lanka.

Introduction: Screening can facilitate early detection and management of obstructive sleep apnoea (OSA) during pregnancy and improve pregnancy outcomes. Our aim was to determine the validity of the Sinhala translation of the Berlin and STOP-Bang questionnaires to detect the OSA risk among Sri Lankan antenatal women.
Methods: Berlin and the STOP-Bang questionnaires were translated to Sinhala language using the standard translation/ back-translation method. Face, content, and consensual validity of the Sinhala versions of Berlin (Berlin-S) and STOP-Bang (STOPBang-S) questionnaires were determined through a modified Delphi process conducted among respiratory physicians. These validated versions were administered to 200 antenatal women at selected antenatal clinics. The exploratory and confirmatory factor analyses (EFA and CFA) were performed. Internal consistency was assessed. Test-retest reliability and Inter-interviewer reliability for these questionnaires were assessed using Cohen’s kappa (k) and intra class correlation coefficient (ICC) values, respectively.
Results: Berlin-S and STOP-Bang-S showed good content, consensual and face validity. The EFA for Berlin-S confirmed a three-factor model compatible with the original instrument but CFA confirmed a one-factor model. The EFA for STOP-Bang-S confirmed a two-factor model. The CFA confirmed a one-factor model that was compatible with the original factor structure. The internal consistency of Berlin-S and STOP-Bang-S were satisfactory. Testretest reliability of Berlin-S and STOP-Bang-S were high for Berlin-S categories (k 0.828 [95% CI: 0.65-1.00]) and STOP-Bang-S score (ICC 0.982 [95% CI: 0.954-0.993]) respectively. The Cohen’s kappa value for the Inter-interviewer reliability of Berlin-S categories was 1.00 (95% CI: 1.00-1.00) and the ICC of STOP-Bang-S total score were 0.992 (95% CI: 0.960-0.994).
Conclusions: The Sinhala versions of Berlin and STOP-Bang questionnaires are valid and reliable tools to screen for OSA risk among antenatal women in Sri Lanka.
A Study of Electrolyte Imbalance in Coronavirus Disease-2019 at a Rural Tertiary Health Care Center
Authors: Sheeba R. , Vishwanathan Dinesh Kumar , Kamath Vasantha
Published: December 2022

Background:

With the ongoing onslaught of coronavirus disease-2019 (COVID-19) pandemic, identifying factors predicting the disease course and outcome become immensely important. Although globally reported, a potential association between electrolyte disturbance and COVID-19 disease has not been well researched. Dyselectrolytemia not only impacts patient care but also provides insight into the pathophysiology of COVID-19.

Aims and Objectives:

Our aim was to study electrolyte disturbances among COVID-19 patients and its impact on the disease outcome.

Materials and Methods:

This was a retrospective observational study conducted in a total of 397 patients detected to have electrolyte abnormalities among 2914 adult inpatients, diagnosed with COVID 19 infection in a tertiary care center over a period of 10 months (July 2020–December 2020 and April 2021–July 2021).

Results:

A total of 2914 patients were diagnosed with COVID-19 of whom 397 (13.62%) patients were found to have an electrolyte imbalance. Hyponatremia (n = 199) 51% was the most common electrolyte disturbance followed by hypokalemia (n = 94) 24.3% and mixed electrolyte abnormality (n = 81) 20.4%. Electrolyte imbalance was directly related to the clinical outcome of the disease which was statistically significant P = 0.0001.

Conclusion:

Hyponatremia has a significant direct correlation with mortality in patients with COVID-19. However, hypokalemia, hyperkalemia, and hypernatremia also influence the disease outcome. We recommend that the estimation of electrolytes should be done routinely for all hospitalized patients with COVID-19 as it adds to the prognostication of these patients.

Authors: Bhattacharyya Kali Sankar , Paul Pritama , Era Nikhil , Paul Sritama , Paul Uttam Kumar
Published: December 2022

Labial adhesion is a common condition found in girls before puberty. All the patients (n = 15) in this series were diagnosed clinically, and routine blood and urine examinations were normal. Mometasone cream was applied topically over the labial adhesions with a positive therapeutic response within 3–8 weeks of treatment. Recurrences of adhesions were found only in two patients who discontinued the treatment after recovery, and repetition of the treatment for 8 weeks solved the issue. Nonsignificant side effects were seen only in two patients. Hence, it can be concluded that mometasone cream is an effective method of treatment for labial adhesions.

Authors: Basu Keya , Karmakar Subhrajyoti , Bhunia Abhirup , Addya Soma , Sengupta Moumita , Chowdhury Arpita Roy
Published: December 2022

Context:

Up to 60% of patients with systemic lupus erythematosus develop lupus nephritis (LN). Tubulointerstitial nephritis (TIN) includes interstitial inflammation, tubulitis, tubular atrophy (TA), and interstitial fibrosis. These are considered independent risk factors for renal outcome.

Aims:

To evaluate the occurrence of TIN in LN and to correlate it with clinical and histopathological variables and renal outcome.

Settings and Design:

It was a prospective, single-center study.

Subjects and Methods:

One hundred and thirty-two LN cases were evaluated. Light microscopic scoring of interstitial inflammation, fibrosis, and TA was done as follows: 0 (nil); 1+ (mild - <25% of the area of observed cortex); 2+ (moderate - >25% to 50% of the area of observed cortex); 3+ (severe - >50% of the area of observed cortex). For direct immunofluorescence study, fluorescein isothiocyanate-conjugated polyclonal rabbit antisera against human IgG, IgA, IgM, C3c, C1q, kappa, and lambda antibodies (DAKO, Germany) were used.

Statistical Analysis Used:

Statistical software GraphPad Prism version 6.1.

Results:

Significant TIN was present in 6% of cases associated with high National Institutes of Health activity and chronicity indices irrespective of the modified International Society of Nephrology and Renal Pathology Society class of LN. In the cases where inflammation and fibrosis are marked, significantly raised serum creatinine, low estimated glomerular filtration rate, high 24-h urinary protein excretion, and reduced survival without any complete remission were seen. Severe interstitial and tubular inflammations without chronicity were also associated with low survival rate due to frequent relapse and significant hypertension.

Conclusions:

Activity and chronicity indices describing TIN components become essential to predict the survival, therapeutic response, and disease prognosis in LN.

Monkeypox: Current trends and therapeutic challenges
Authors: Paul Pritama , Singh Ritika , Era Nikhil , Paul Sritama , Paul Uttam Kumar
Published: December 2022

Monkeypox is a viral zoonotic disease that mostly affects tropical rainforest regions of Central and West Africa, with infrequent exportations to other parts of the world. The cause of monkeypox is the monkeypox virus, a species of the Orthopoxvirus genus in the family Poxviridae. Monkeypox often has symptoms that last between 2 and 4 weeks and is a self-limiting condition. Severe cases could exist. Monkeypox can be spread to humans by close contact with infected animals or people, as well as through coming into contact with contaminated materials. By coming into intimate contact with lesions, bodily fluids, respiratory droplets, and contaminated things like bedding, the monkeypox virus can be transferred from one person to another. The smallpox immunizations used in the smallpox eradication campaign also provided immunity to that illness. One of the more recent vaccinations, which is now accessible, is approved for the protection of monkeypox. Hexadecyloxypropyl-cidofovir (CDV) has superior oral bioavailability, less toxicity, and improved cellular penetration compared to CDV, administered intravenously. The European Medicines Agency authorized tecovirimat, an antiviral medicine developed to treat smallpox, to treat monkeypox in 2022 on the basis of data from both animal and human testing. It is still not readily accessible.
To ascertain the plasma concentration of propofol to achieve bispectral index-guided sedation using a target-controlled infusion in patients undergoing elective surgeries under neuraxial anaesthesia
Authors: Chhabra Deepak , Bhatia Pradeep , Sethi Priyanka , Kaloria Narender , Kumar Mritunjay , Kaur Manbir
Published: December 2022

Background and Aims:

Sedation improves patient satisfaction, comfort and acceptance of regional anaesthesia. Propofol using bispectral index (BIS)/target-controlled infusion (TCI) system can be an optimal method of sedation, as it combines objective measurement of sedation using BIS along with maintenance of a steady plasma concentration of propofol with the TCI device. The aim of this study was to ascertain the dose and safety of propofol using BIS/TCI system for sedation in patients undergoing surgeries under neuraxial anaesthesia.

Methods:

One hundred and seven adult patients, undergoing elective surgical procedures under spinal or combined spinal epidural anaesthesia, were recruited. Propofol infusion was started with TCI at an initial target plasma concentration (Cpt) of 1.2 μg/mL, and after equilibration between Cpt and effect site concentration (Ce), propofol was then adjusted in increments and/or decrements of 0.2 μg/mL in order to maintain a BIS value between 60 and 80. The average time to reach BIS = 80 after starting infusion was 7.32 ± 3.13 minutes. The objective was to calculate mean Cpt value maintaining BIS between 60 and 80 and to observe recovery time and complications.

Results:

Mean Cpt value was 1.13 ± 0.17 mg/mL with 95% confidence interval (1.10–1.16 μg/mL). In 85% of patients, a BIS value of 60–80 was maintained at Cpt ≤ 1.2 μg/mL. No patient had severe complications requiring stoppage of infusion.

Conclusion:

Propofol sedation using BIS/TCI system can provide safe and convenient sedation during neuraxial anaesthesia at very low plasma concentration, Cpt ≤ 1.2 μg/mL in majority of patients. There were no periprocedural complications, and recovery was rapid.
Sea buckthorn against periodontitis
Authors: Santosh Susmitha , Babitha GA , Holla K Shashanka , Prakash Shobha , Suresh K , Bhat G Kishore
Published: December 2022

Background:

Sea buckthorn (SBT) (Hippophae rhamnoides, L., Family Elaeagnaceae) is a small orange yellow-to-red–colored fruit, found on high altitudes in several Asian and European countries. SBT is referred to as “wonder plant” as seed oil is rich in Vitamins A, E, K, carotenoids, and phytosterols. SBT pulp is an excellent source of omega-7 fatty acids, while seed oil has high content of omega-3, 6, and 9 fatty acids. There are limited studies to evaluate its effects on periodontal pathogens.

Objectives:

(i) To evaluate the effect of SBT on clinical parameters (plaque index, gingival bleeding index, pocket depth, and clinical attachment level) in periodontitis patients. (ii) To evaluate the effect of SBT on microbiological parameters, i.e., anaerobic culture for Aggregatibacter actinomycetemcomitans (Aa) levels before and after nonsurgical therapy in chronic periodontitis patients. (iii) To compare the efficacy of SBT as an adjunct to nonsurgical therapy and nonsurgical therapy alone on Aa.

Materials and Methods:

A total of 24 patients were randomly allocated to control group (12 patients) that underwent scaling and root planing (SRP alone) and test group (12 patients) that underwent SRP along with intrasulcular SBT thixotropic solution delivery as local drug delivery (SRP + SBT). Clinical and microbial parameters are assessed at baseline and after 1 month.

Results:

The treatment modality used showed statistically significant improvement in both clinical and microbial parameters in test group compared to the control group.

Conclusion:

SBT was an effective adjunct in improving the clinical and microbial parameters compared to SRP alone in periodontitis patients.
Vestibular incision subperiosteal tunnel access and multilayered advanced platelet rich fibrin membrane for management of multiple gingival recessions
Authors: Raj Rishi , Gowda Triveni Mavinakote , Shah Rucha , Pooja N
Published: December 2022

Treatment of multiple recession defects on the lingual is challenging owing to the site-specific anatomical features of this region. Surgical approaches based on the use of subepithelial connective tissue grafts are considered the “gold standard” for the treatment but represent various complications and morbidity. Various techniques have been suggested for the treatment of multiple adjacent recessions with less patient discomfort and enhanced esthetics. Advanced platelet-rich fibrin (A-PRF) has been shown to promote soft-tissue healing. A-PRF is a fibrin matrix network, in which platelets are trapped and release a high amount of growth factors which take part in soft tissue and hard tissue repair and regeneration. The current case report introduces a novel, minimally invasive predictable approach applicable for both isolated as well as multiple defects with the use of the (vestibular incision subperiosteal tunnel access) technique in combination with a multilayered A-PRF membrane.

In Group I, after SRP, chlorhexidine gel (chlosite) was inserted up to the base of the pocket. In Group II and III, doxycycline gel and hyaluronic acid gel, respectively, were inserted up to the base of the pocket after SRP, and Group IV was used as a control. The clinical parameters such as probing pocket depth (PPD), relative attachment level (RAL), and gingival index (GI) were recorded at baseline, 6 weeks, and 3 months.

Results:

There was statistically highly significant improvement in all the clinical parameters at 6 weeks and 3 months when chlorhexidine, doxycycline, and hyaluronic acid gel were used as an adjunct to SRP. Chlosite group showed statistically significant improvement in PPD and RAL as compared to other groups. With regard to GI, Group I showed a statistically significant reduction when compared to Group III (hyaluronic acid group) and IV (control group). However, the reduction was not statistically significant when compared to Group II (doxycycline group). When doxycycline and hyaluronic acid gel were used as an adjunct to SRP, it resulted in greater improvement in clinical parameters as compared to SRP alone, but the results were not statistically significant. Results were comparable for both drugs.
Estructura simbólica de ajuste. Una propuesta descriptiva a través de 6 casos de migración mediatizada
Authors: Diz-Casal Javier , Riffo-Pavón Ignacio
Published: December 2022

Se propone elaborar una reflexión descriptiva de naturaleza cualitativa donde se busca establecer elementos de convergencia sobre ciertos discursos en torno a contextos migratorios desde uno de los conceptos planteados por el sociólogo Manuel Antonio Baeza: estructura simbólica de ajuste. Se determina la profundización en la irrupción de nuevos discursos e ideaciones en torno a las migraciones desde la divulgación de los medios de comunicación y su impacto en la intersubjetividad. Los mass medias fungen como transmisores de las significaciones sociales, brindando representaciones de la realidad que emanan desde el imaginario compartido socialmente. Así, esta propuesta se interesa por la pertinencia del concepto de estructura simbólica de ajuste para la investigación del fenómeno social de la migración, a partir de los planos de significación social -representaciones e imaginarios- transmitidos en la prensa. Los objetivos principales son la detección de representaciones e imaginarios y la propuesta de la estructura simbólica de ajuste para explicar la realidad social migratoria. Este artículo, de carácter cualitativo, se focaliza en seis casos que han sido tratados en las plataformas mediáticas. Se recurrió a medios y agencias de comunicación escrita iberoamericanas, norteamericanas y europeas, donde se seleccionó una muestra de noticias que fueron analizadas mediante la operacionalización de la teoría del framing, mediante un análisis con MAXQDA y un análisis de contenido. Se obtuvo, principalmente, que la estructura simbólica de ajuste en relación a la temática de la inmigración se constituye a partir del imaginario de la migración noticiada y el imaginario del miedo e inferioridad de la otredad; a la vez que estos imaginarios nutren seis representaciones sociales que significan a las personas migrantes con la negatividad, los problemas y la irregularidad.
El Caso Andrés Pereira Salsberg: La Presencia de la Ausencia de las Desapariciones Forzadas en Chile
Authors: Lira Elizabeth , Rojas Hugo
Published: December 2022

Este artículo ofrece un análisis en profundidad del caso judicial de Andrés Pereira Salsberg. Describe los obstáculos y dificultades de la larga y compleja búsqueda de sus familiares para dar con su paradero. Las numerosas acciones ante los tribunales, iniciadas en 1973, finalmente concluyeron con la sentencia condenatoria dictada por la Corte Suprema el 14 de junio de 2022. Los familiares de las víctimas de desaparición forzada convirtieron su ausencia en una búsqueda activa y sostenida para alcanzar verdad, justicia y reparación a través de los tribunales. Este caso muestra el cambio de paradigma en el tratamiento del pasado conflictivo, transitando desde la impunidad de la amnistía a la sanción judicial de los responsables. Ilustra los cambios en el rol del poder judicial desde los inicios de la transición a la democracia en 1990 hasta el presente, y el reconocimiento progresivo de los derechos de las víctimas.
Beyond aesthetics and appearance: Ẹpa masks of Iyah Gbẹdẹ
Authors: Ayinmode Stephen Ayodele
Published: December 2022

Ẹpa masks are produced in order to enable the spirit of Ẹpa deity (Elela in Iyah Gbede) to be felt and appreciated by the society and to appear as a visible form or dramatic representation of mythical actions. However, there are substantial differences between some of the most spectacular and complex Ẹpa masks ever carved as far back as early to mid-20th century by some notable Yorùbá woodcarvers in southwestern Nigeria with those found nowadays in Iyah Gbede and some other Ẹpa practicing communities. Craftsmanship and form were considerations in the aesthetic judgment of the masks and headdresses among the masqueraders and the devotees of Ẹpa deity, but not necessarily the primary ethos. This paper therefore focused predominantly on visual element qualities and morphological presence in all Ẹpa masks and headdresses found in Iyah Gbede. The paper explored brief history and proceedings of Ẹpa masquerade tradition in Iyah Gbede as well as examining the visual content (thematic analysis) of the masks and headdresses to reveal a nexus between various creative traits and styles displayed by carvers in Iyah Gbede. Fourteen (14) major mask types found in the Iyah Gbede were identified from both conventional and unconventional (plastic) point of view. This paper concluded and affirmed that some new Ẹpa headdress were reproduced in Iyah Gbede when some of the ancient headdress was stolen; while some other headdresses were refurbished with paint.
Dikdörtgen Geometriye Sahip Kapların Soğuk Derin Çekilmesinde Kalıp Geometrisinin Kap Hasarları Üzerindeki Etkisi
Authors: ÖZEK Cebeli
Published: December 2022

Derin çekme, zımba kuvveti uygulanarak sac malzemenin kalıp boşluğuna akışıdır. Derin çekmede, düz ince tabakalar arasında sacı istenen şekle getirmek için zımba kullanılarak sacı merkez kısmından kalıp boşluğuna iterek kaplar üretilmektedir. Derin çekilmiş kaplarda kabın köşe yarıçaplarında boyun oluşumu veya çatlamaların oluşması nedeniyle daha yüksek çekme oranları elde edilememektedir. Bunun için derin çekme işleminin başarılı olmasında uygun işlem parametrelerinin doğru seçilmesi önemlidir. Bu makalede, dikdörtgen geometriye sahip kapların derin çekilmesinde matris üst yüzeyine ve pot çemberinin alt yüzeyine açılar verilerek matris geometrisinin, kap kesit incelmeleri ve hasarları üzerinde olan etkileri tespit edilmiştir. Bunun için matris üst yüzeyine/pot çemberi alt yüzeyine 0°, 3°, 6° ve 9°’lik açılar verilmiştir. Pot çemberi kuvveti sabit 1800 daN ve stampa hızı da sabit 4 mm/s olarak uygulanmıştır. Derin çekme işlemlerinde, matris/stampa arası boşluk 1.2 mm, stampa uç ve kenar radyüsleri ile matris ağız yarıçapları 6 mm alınmıştır. Çalışmada kalınlığı 1 mm olan St37 çeliği kullanılmıştır. Cidar kalınlıkları Mitutoyo LH-600E hassas lineer ölçüm cihazında 0.001 hassasiyetinde nokta temaslı olarak ölçülmüştür. Kap yükseklikleri artıkça kaplardaki cidar incelmelerinin arttığı, maksimum incelmenin kabın alt kısımlarındaki köşelerde meydana geldiği ve bu değerin 0,373 mm olduğu tespit edilmiştir. Plastik deformasyonun en çok etkilediği bölge kap alt bölgesidir. Bu bölgede deformasyon sertleşmesi nedeniyle maksimum basma ve çekme kuvvetleri oluşmakta ve dolayısıyla maksimum gerilme ve sertlik bu kısımda meydana gelmiştir. Maksimum sertlik kabın tabanının olduğu bölgede ve 61.4 HRC olarak ölçülmüştür. Minimum sertlik kap üst bölgesinde ölçülmüştür. Kabın üst ağız kısımlarına doğru sertliğin daha da düştüğü ve 43.8 HRC olduğu görülmüştür. Ortalama sertlik değeri ise 53.1 HRC olarak tespit edilmiştir. Sonuç olarak, dikdörtgen geometriye sahip kapların soğuk derin çekilmesinde, matris üst yüzeyine ve pot çemberinin alt yüzeyine açılar verilerek kalıp geometrisinin, kap cidar kalınlık değişimleri ve kap hasarları üzerinde önemli bir etkisinin olduğu tespit edilmiştir.
Quanto vale o Vale: as dinâmicas urbanas da reforma do Vale do Anhangabaú frente à prática do skate de rua
Authors: David José Vitor Carignato
Published: December 2022

O Vale do Anhangabaú, espaço histórico do centro de São Paulo, passou por uma reforma recentemente, inciada em 2019 e finalizada em 2021. Uma intervenção urbana que gerou muitas polêmicas. Discutiu-se a real necessidade de tal intervenção, orçada em cerca de 100 milhões de reais, numa São Paulo cada vez mais segregada e desigual. Dentro deste contexto urbano, um grupo que ocupa o Vale do Anhangabaú por mais de 30 anos se levantou contra a destruição de um espaço tão caro à eles: os skatistas de rua. Neste trabalho, se faz um panorama geral e análise da ocupação skatista no Vale do Anhangabaú e um balanço do movimento organizado por eles, o “Salve o Vale”, que acarretou em mudanças no projeto de reforma. Análise feita trazendo importantes autores do debate urbano, como David Harvey, Henri Lefebvre, Jane Jacobs, Heitor Frúgoli Jr, entre outros.
