Authors: Rabelo Amanda Oliveira , Souza Fabiano dos Santos , Gomes Georgia Regina Rodrigues
Published: December 2024

This thematic call aims to bring together articles that reflect on issues related to teacher initiation during the covid-19 pandemic, in a movement of resistance and survival for the school, the teacher, and the future teacher, focusing on both the impossibilities and the possibilities realized in practice. In it, we present articles about the various programs and strategies used to adapt to the new impositions presented by the pandemic. The programs analyzed were PIBID, PRP, Teacher Residence, PID, and Teacher Initiation itself. We can conclude, from the articles presented, that the difficulties were many, but several possibilities emerged amidst reflections on initial and continuing teacher education, innovative and motivating pedagogical practices that benefited not only the students/teachers in initial education but also the teachers of basic schools and their respective students, in a partnership between university and school, in the relationship between teaching and learning, in a true theoretical-practical formation. Thus, we believe that this thematic call may contribute to reflections on the various forms of teacher education and pedagogical practices, not only in the context of the pandemic but also in the production of innovative strategies that can be developed in all educational contexts.

Published: December 2024

The sepiolite and Al2O3-doped sepiolite contents in the as-received sepiolite/epoxy systems were maintained at 2 and 4wt %, respectively. The flame-retardant capabilities and combustion behavior of Al2O3-doped sepiolite in epoxy resin were meticulously evaluated through a series of tests including cone calorimetry (CC), limiting oxygen index (LOI), dynamic mechanical analysis (DMA), and thermogravimetric analysis (TGA). Several features, including degradation kinetics, combustion characteristics, thermomechanical properties, flame retardancy, and thermal degradation were evaluated with the intention of drawing comparisons to standard sepiolite. The findings from the studies were positive. In contrast, Al2O3-doped sepiolite not only further improved the LOI values and char formation post-cone testing but also decreased the previously mentioned combustion-related parameters in the composites. A potential synergistic interaction between sepiolite and Al2O3 in augmenting the flame retardancy of the composite was suggested. The thermal degradation of composites was only little affected by addition of sepiolite, although Al2O3-doped sepiolite addition seemed to speed up the deterioration process. The epoxy composite’s glass transition temperature (Tg) was shown to increase when sepiolite or Al2O3-doped sepiolite was added, as determined by DMA. The findings presented in this research provided a practical approach to improving the fireproofing of polymers. Keywords: Al2O3-doped sepiolite; TGA, flame retardancy; DSC, epoxy; thermal properties.

Published: December 2024

With the proposal of carbon peaking and carbon neutrality and the need for environmental protection, carbon dioxide capture, utilization, and storage (CCUS) technology has become a focus of attention and brought great vitality to the corresponding industries. Many energy and chemical companies are trying to use this technology to reduce carbon emissions, and liquefied carbon dioxide carriers are an indispensable link in this industrial chain. In the process of carbon dioxide transport, both low temperature and high pressure are used to make carbon dioxide liquefied. Therefore, the material of carbon dioxide storage tanks should not only have high strength but also have good low-temperature toughness and crack resistance. In this paper, a high-strength and low-temperature steel with a thickness of 50 mm was developed. The steel is designed to be micro-alloyed by Nb and Ti, and alloy elements of Cr, Ni, and Mo are added to ensure high strength up to 690 MPa grade. The mechanical properties of the steel sheets fully meet the requirements of the standard EN10028-6. The microstructure of the steel plate is mainly tempered martensite. The ultrasonic flaw detection quality of the steel plate meets the requirements of the T1 level of standard NB/T47013.3. The mechanical properties of the steel sheets keep to a high level after PWHT. This newly developed steel meets the following requirements of a carbon dioxide transport ship storage tank.

Authors: Demirtas Levent , Guclu Aydin , Erdur Fatih Mehmet , Akbas Emin Murat , Ozcicek Adalet , Onk Didem , Turkmen Kultigin
Published: December 2024

The prevalence of diabetes mellitus (DM) is increasing secondary to increased consumption of food and decreased physical activity worldwide. Hyperglycaemia, insulin resistance and hypertrophy of pancreatic beta cells occur in the early phase of diabetes. However, with the progression of diabetes, dysfunction and loss of beta cells occur in both types 1 and 2 DM. Programmed cell death also named apoptosis is found to be associated with diabetes, and apoptosis of beta cells might be the main mechanism of relative insulin deficiency in DM. Autophagic cell death and apoptosis are not entirely distinct programmed cell death mechanisms and share many of the regulator proteins. These processes can occur in both physiologic and pathologic conditions including DM. Besides these two important pathways, endoplasmic reticulum (ER) also acts as a cell sensor to monitor and maintain cellular homeostasis. ER stress has been found to be associated with autophagy and apoptosis. This review was aimed to describe the interactions between apoptosis, autophagy and ER stress pathways in DM.
Unmasking rhabdomyosarcoma: Fine-needle aspiration cytology evaluation of hand swelling in a 2-year-old girl
Authors: Sharma Raghav , Pendharkar Chinmay Shrikrishna , Singh Vikram , Venkatesan Somasundaram
Published: December 2024

Rhabdomyosarcoma (RMS) is a malignant soft-tissue sarcoma originating from primitive mesenchymal cells, typically differentiating into skeletal tissue. It is the most common soft-tissue sarcoma in children and represents 3% of childhood malignancies. Despite advances, high-risk and recurrent RMS have poor survival rates with significant long-term toxicities from current therapies. Most cases are sporadic, though some are linked to familial syndromes. This case highlights the importance of early RMS diagnosis, as timely identification can improve management outcomes. The use of fine-needle aspiration cytology (FNAC) in this young patient demonstrates a minimally invasive approach, reducing diagnostic delay and associated morbidity. We describe a case of a 2-year-old girl who presented with swelling on the dorsum of the right hand, initially suspected to be a nerve sheath tumour based on radiological findings. FNAC smears showed small round blue cells that mimicked lymphoma on MGG and PAP staining. However, a definitive diagnosis of RMS was made after detailed cytomorphological analysis, supported by immunocytochemistry (ICC) and flow cytometry. This case illustrates the precision and efficacy of FNAC, along with the critical utility of ICC in confirming the diagnosis.

Authors: Bali N. Kavitha , Reddy K. Ramakrishna , Rao Kalyan , Stanley Reshma , Bendre Rajesh
Published: December 2024

Langerhans cell histiocytosis (LCH) is an uncommon condition marked by an increase in Langerhans cells, a type of dendritic cell, with primary thyroid involvement being particularly rare, representing less than 1% of all cases. In a notable case, a 32-year-old woman exhibited an enlarged thyroid gland and underwent surgical resection, where pathological analysis confirmed the presence of Langerhans cells in her thyroid tissue. Comprehensive systemic evaluations, including imaging and blood tests, showed no signs of multi-systemic involvement, suggesting that the disease was confined to the thyroid. This highlights that primary thyroid LCH, though rare, can mimic symptoms of other thyroid disorders and emphasizes the importance of histological diagnosis over extensive systemic screening when the disease appears localized. Further research is essential to enhance understanding and management strategies for this unique condition.
Incidence of Post-operative Neuropathic Pain in Transoral Thyroidectomy Patients: A Prospective Observational Pilot Study
Authors: Kumar Sanjay , Khuba Sandeep , Banerjee Anwesha , Chand Gyan , Agrawal Ritika
Published: December 2024

Introduction:

Thyroid surgery has advanced significantly, but still choice of surgery is controversial due to the relative advantages and disadvantages of open thyroidectomy and endoscopic thyroid surgery (endoscopic thyroidectomy [ET]). This study aims to determine the incidence of post-surgical neuropathic pain after transoral vestibular ET (TOVA-ET).

Methods:

This was a single-centre prospective, observational pilot study. Sixty-five patients underwent TOVA-ET and 50 were followed till 90 days. Incidence, character and the severity of pain were measured using Douleur Neuropathique 4 (DN4) and Visual Analogue Scale (VAS) score.

Results:

On the post-operative day 15, day 30 and day 90, incidences of DN4 pain are 70%, 40% and 24% with median DN4 pain score 5, 3 and 2, respectively, which were also evident to a significant reduction in DN4 pain score between day 15 and day 30, day 15 and day 90 and day 30 and day 90. The mean VAS pain score was 37.8 (day 15), 20.8 (day 30) and 9.7 (day 90). Median VAS pain score was 40 (day 15), 20 (day 30) and 10 (day 90) and difference between time points was statistically significant (P < 0.001), followed by multiple comparisons indicated a significant reduction in pain score between day 15 and day 30, day 15 and day 90 and day 30 and day 90 (each P < 0.05).

Conclusion:

TOVA-ET has a significant incidence of post-surgical neuropathic pain, commonly brushing, pins and needle sensation in the mouth, affecting quality of life. Although pain scores reduce significantly over time, these complaints are often ignored in the shadows of other seemingly important post-operative concerns. This study will delineate the alarming complication that needs adequate attention.
An Integrated and Miniaturized Multi-Channel Distributed Cooperative
Spectrum Sensing Technology Based on Zynq
Authors: Chen Wangjie , Yang Jian , Zhu Weiqiang , Shi Songhua , Zhou Mingyu , Fan Zhenhong
Published: December 2024

In response to the escalating demand for high-performance, miniaturized, and
integrated radio frequency (RF) systems, this research explores the application
of the Zynq UltraScale+ RFSoC XCZU47DR chip in the realm of integrated RF
transceiver technology. An 8-channel, 4.8Gsps multi-channel distributed
collaborative spectrum sensing architecture has been designed, incorporating
lightweight IQ neural network, which comprises a convolutional layer, three
Bottleneck Units (BNU), a Global Average Pooling (GAP) layer, and a Fully
Connected (FC) layer. Notably, each BNU encapsulates one or two inverted
bottleneck residual blocks that integrate the concepts of inverted residual
blocks and linear bottlenecks. The parameter counts and computational complexity
associated with the convolution operation are significantly reduced to merely
11.89% of those required by traditional networks. The performance metrics of the
hardware circuit were validated through a constructed test system. Within a 2GHz
instantaneous bandwidth, the amplitude consistency between Analog-to-Digital
Converter (ADC) channels is less than 1dB, and the effective number of bits
exceeds 7.3 bits. Simulation results demonstrate that, at a Signal-to-Noise
Ratio (SNR) of -10dB with a false alarm probability of 0.5%, the detection
probability of the collaborative spectrum sensing algorithm reaches 91.13%,
marking a 6dB enhancement over conventional energy detection methods. This
achievement underscores the technology’s substantial advantage in boosting
spectrum sensing capabilities, providing novel perspectives for the design of RF
systems and the evolution of wireless communication technologies.
There are no words

This study partially remedies the neglect in current Translation Studies research on artistic or invented languages, and interlinguistics more broadly. The work investigates the drama of translatorial sense-making, and how radical difference is encoded as (mis)translation phenomena in many literary works. I consider limit cases (asemia, glyptolalia, pataphilology) and scrutinize the apparent untranslatability posed by others (musical or pictographic languages), and even entertain works translated into diagrammatic images or “ekphrastic translations”. However, the “cryptographic-translation idea” of languages as mutually decodable makes for pseudo-invented languages in those cases in which a posteriori constructed languages are in fact existing natural languages in disguise. At bottom, the study is a meditation on how invented languages are used in transfiction. To name but four functions: 1) as a poetics of defamiliarization of the everyday, 2) as a vehicle of ideological ends (e.g. preventing understanding), 3) as parody (for example, of academic discourse), and 4) as metacommentary on translation. Embracing translation as multi-sensorial, multimodal, and interrelational between form, sound, and text, and works actively or ostensibly defying or transcending translation, I utilize illustrative microcases from linguistic fantasies (linguistic fiction), parables, poetry, concrete poetry, and text-based art.
Advertising in the Latvian press: From early editions to modern times
Authors: Ločmele Gunta
Published: December 2024

The publication of Latviešu Avīzes, the first Latvian newspaper, on January 5, 1822, marked the birth of Latvian print advertising. In the early days of Latviešu Avīzes, advertising emerged from news articles that incorporated promotional elements and from classified advertisements. Since its formative years in the early 19th century, Latvian advertising has undergone several notable transformations. The contrast with modern-day advertising in popular magazines is showcased in various examples of changing values, foreign language influence in translations, brands, terminology and multimodality. The analysed examples show that advertising, in particular translated ads, has influenced and continues to influence the development of the Latvian language.

Authors: Diabaté Ibrahima , Malick Diaw El Hadji , Diallo Ismaïla
Published: December 2024

Context and objective. Perineo-scrotal gangrene (PSG) is a necrotizing fasciitis of the scrotum, which may extend to the perineum or beyond. Its surgical management leaves a loss of perineo-scrotal substance, which sometimes needs to be reconstructed. The aim of this study was to evaluate scrotal reconstruction by testicular transposition in our practice. Methods. Retrospective study of patients who underwent scrotal reconstruction by testicular transposition for a PSG in the Urology Department of the CHRASM in Louga (Senegal). The surgical techniques used were as follows: Step 1: Testicular burial on the anteromedial aspect of the thigh, under the skin; Step 2: Transposition of the skin-covered testicles to their anatomical position. Results. Ten patients were operated on using this technique. The PSG were of urogenital origin (4 cases), anal origin (2 cases) and of an unidentified origin (4 cases). Post-operative care was straightforward. Two patients did not present for the second operation. The cosmetic and anatomical result was considered good in terms of body image restoration in 8 patients. Conclusion. Scrotal reconstruction after PSG is challenging. Testicular transposition, performed in 2 stages, is a simple technique with good results.

Hemophilia is a constitutional disease, inherited in an X-linked recessive mode. We report a case of superinfected hemarthrosis revealing moderate hemophilia A in an adolescent. This was a 17-year-old patient hospitalized with a painful swelling of the left knee that had been evolving for 3 weeks. Examination revealed a fever of 39.8ºC, a respiratory rate of 28 cycles/min, and monoarthritis of the left knee. Biological tests revealed a prolongation of the activated partial thromboplastin time (APTT) to 2.91. Coagulation factor VIII levels were found to be 2.4%. A puncture of the knee yielded 75 cc of sero-haematic fluid. A cytobacteriological examination of the joint fluid revealed staphylococcus. Magnetic resonance imaging (MRI) revealed extensive hydarthrosis. A 15-day course of injectable factor VIII was combined with antibiotic therapy. The evolution was favorable, with a regression of symptoms. The treatment of superinfected hemarthrosis is an emergency, and multiple skills are required to provide appropriate management.

Context and objective. Urinary screening is a useful and inexpensive tool for the early detection of urinary abnormalities in asymptomatic children. This might contribute to the prevention of chronic kidney disease later in life. This study aimed to determine the prevalence of urinary abnormalities among school children in the town of Kisantu. Methods. In a cross-sectional study, apparently healthy children aged 6 to 16 years were randomly recruited from 7 schools. Using dipstick test, recorded parameters of interest were proteinuria, hematuria, urinary tract infection (defined as nitrite positive and/or leukocyte positive). Logistic regression was used to assess the determinants of urinary abnormalities in this population. Results. Out of 253 children, the prevalence of urinary abnormalities was 51.8% (131/253). Twenty-four (9.5%) presented with hematuria and only 1 (0.4 %) presented with proteinuria on dipstick. Urinary tract infection was found in 123 children (48.6 %).  In multivariate regression analysis, female sex emerged as the major determinant of urinary tract infection (OR 2.79, CI 95 % 1.67 – 4.65). Conclusion. This campaign showed the significant presence of urinary abnormalities and more particularly urinary tract infection in apparently healthy children in a rural school setting. Hence the importance of urine screening for prevention and early management of kidney diseases.

Context and objective. Pursuing medical training is a well-established cause of depression in students, which increases with the number of years of study. This study aimed to explore the association between academic performance and depression among students. Methods. A pilot cross-sectional study was conducted among students enrolled in the fourth- to seventh-year faculty of Medicine at the University of Goma, Democratic Republic of Congo (DRC). Multivariate logistic regression models were performed to explore the association between academic performance and depression using the Beck Depression Inventory-II (BDI-II). Results. In total, 497 students were interviewed. The prevalence of depression was 60 % with 10.6 % of participants having severe depression. Participants who never repeated an academic year were 1.22 times more likely to have depression compared to those who had ever repeated an academic year during their medical training. Having a history of chronic headaches and using alcohol were the factors associated with depression, while being in the last year of medical training showed a protective effect on depression in medical students. Conclusion. Depression is highly prevalent among fourth- to seventh-year medical students enrolled at the University of Goma. Depression is more likely to be reported in medical students who never repeated an academic year in their academic journey. The present study emphasizes a need of educational interventions targeting the student’s mental health well-being regardless their academic performance during the previous academic years.

Context and objective. Thyroid nodules are a common diagnostic problem in resource-limited countries. The aim of the present study was to evaluate the diagnostic performance of the European Thyroid Imaging Reporting and Data System (EU-TIRADS) using ultrasound score. Methods. A series of cases of thyroid nodules (isolated or atypical within a multinodular goiter) diagnosed by ultrasound and operated on, between January 2017 and December 2021, in the ENT Department of the Sylvanus Olympio University Hospital in Lomé was retrospectively analyzed. The diagnostic value (sensitivity, specificity, positive predictive value, negative predictive value and accuracy) of thyroid ultrasound was investigated, taking the anatomopathological finding as a reference. Results. A total of 134 medical records were collected. The mean age was 42.28 ± 12.93 years. Females predominated (94 %). The frequency of thyroid cancer was 8.9 %, with papillary carcinoma predominating, accounting for 91.6% of cancers. On ultrasonography, 24 nodules (18%) were classified EU-TIRADS 2, 72 nodules (54%) EU-TIRADS 3, 19 nodules or 14% EU-TIRADS 4 and 19 (14%) EU-TIRADS 5 nodules. Nodule malignancy increased progressively with EU-TIRADS score. The combination of EU-TIRADS scores 2 and 3 considered benign and the grouping of scores 4 and 5 suggestive of malignant gave a sensitivity, specificity, positive and negative predictive values and accuracy of, respectively, 67% (40-93.3%), 75% (67.7-83.0%), 21% (8.0-34.0%), 96% (91.8-99.8%) and 74.6% with p < 0.004. Conclusion. Thyroid nodules are common, but thyroid cancer remains rare. In the present context, the EU-TIRADS score would be a good tool for recognizing benign nodules, as it would rule out thyroid cancer rather than confirm it.

Is pursuing a PhD without theoretical and conceptual framework a journey without roadmap?
Authors: Oyewobi L.O. , Okanlawon T.T. , Medayese S.O. , Ogunbode E.B. , Jimoh R.A.
Published: December 2024

Theoretical and conceptual frameworks are essential components of the research process, although they are often misinterpreted by doctorate candidates during the development of their dissertation study. The purpose of this paper is to emphasise the critical role that theoretical and conceptual frameworks play in enhancing the rigour and clarity of research. This is an argumentative paper that uses information as evidence to back up its claims. The authors used this methodological framework to espouse the need that doctoral research should have a valid theoretical framework to justify the importance and significance of the work in order to contribute to knowledge in their field of study. The study clarifies two sometimes misinterpreted terms: conceptual and theoretical frameworks. According to the authors, the decision to use a theoretical or conceptual framework is influenced by the research goals, study characteristics, and available literature. Conceptual frameworks are typically used in qualitative and mixed methods research, although theoretical frameworks are used more frequently in quantitative and mixed methods research. Mastery of conceptual and theoretical knowledge in construction management research allows researchers to develop clear, well-structured enquiries, improve methodological rigour, and successfully integrate theory to practice, resulting in innovative ideas in the field. The paper discusses the importance of including a theoretical and/or conceptual framework in a doctoral thesis focussing on construction management research. It states that these frameworks are critical for defining the student's research direction. The study emphasises that understanding 'concept' and 'theory' allows for the successful use of conceptual and theoretical frameworks to provide direction and coherence throughout the research proce

Published: December 2024

Foamed concrete (FC) is a relatively new construction material that has recently gained attention due to its unique properties, such as density and strength-to-weight ratio. This lightweight material makes it easy to form into different shapes and sizes. Its excellent thermal insulation makes it popular for building walls, roofs, and floors. This study investigates the fire resistance and ultrasonic testing of rice husk ash modified foamed concrete. The study adopted a design density of 1600 kg/m3 and a 0.5% water-cement ratio. The concrete was cured in ambient conditions at 7,14, 28, 56, and 90 days. A cube specimen of 100 mm size was used to determine compressive strength, density, fire resistance, and ultrasonic pulse velocity (UPV). The control achieved the maximum compressive strength at 28 days, which achieved 15.85 N/mm2. The fire resistance of FC is reduced as temperature increases. The strength of FC at an elevated temperature of 4000C is minimally reduced. The results proved that the UPV was efficient in proving that the various samples of FC come from the same material (uniform and homogeneous structure) and are classified as good-quality concrete. The findings of this study show that FC with rice husk ash percentage up to 10% did not have a significant difference from the control concrete, while a higher percentage replacement level shows reduced strength. FC is recommended for application in structural lightweight insulating material. RHA is a good pozzolana and can reduce overburden on cement by reducing the quantity of cement used for FC production.
Media Business Ownership and Control in Ghana’s democracy
Authors: Dzisah Wilberforce , Diedong Africanus , Asante James , Asare Kofi
Published: December 2024

The paper examines the problem of media ownership, its control imperatives and the overarching partisanship in Ghana’s democracy. It explicates the challenges posed by media concentration, manipulation, and interference by political actors on the health of Ghana’s democracy. This is a conceptual paper and complemented by theoretical arguments with the findings drawn from analysis of secondary material. Media business ownership and control has a bearing on its operations in both liberal and illiberal democracies. Conceptual and theoretical arguments underlined the study from the standpoint of democratic theory, pluralist media and Marxist media ownership theories. These concepts and theories were engaged to address the state/public and private ownership imperatives in the Ghanaian media ecology. From the study, two findings emerged. First, media business ownership and control are promoting more partisanship and polarization of the citizenry. Secondly, evidence of state control, interference and manipulation in the Ghanaian media space have been reported in this paper. The study concludes that a deliberate policy is required about creating an enabling environment for more entrepreneurs to invest in the media rather than politicians in order to prevent unbridled partisanship and bias. It noted that all stakeholders strive for policy changes which will give true meaning to media independence.

Effective aspects of semiperfect rings
Authors: Wu Huishan
Published: December 2024

This paper studies effective aspects of semiperfect rings from the standpoint of reverse mathematics. Based on first-order Jacobson radicals of rings, we define a ring R with the Jacobson radical Jac(R) to be semiperfect if the quotient ring R/Jac(R) is semisimple, and idempotents of the quotient ring can be lifted to R. Using elementary matrix operations in linear algebra, we show that RCA0 proves a characterization of semiperfect rings in terms of idempotents of rings. Semiperfect rings are generalizations of semisimple rings and local rings, and semiperfect rings R with R/Jac(R) simple are isomorphic to matrix rings over local rings. Based on the effective characterization of semiperfect rings via idempotents, we prove the structure theorem of semiperfect rings R with R/Jac(R) simple in RCA0. Left perfect rings or right perfect rings are always semiperfect. Finally, we provide a proof for the structure theorem of one-sided perfect rings R with R/Jac(R) simple in WKL0.

Feminismo interseccional en el currículo de la educación obligatoria española
Authors: Neubauer Adrian
Published: December 2024

Este trabajo tiene dos objetivos: (1) analizar cómo integra la perspectiva interseccional la LOMLOE a la hora de abordar la igualdad de género y, también, (2) identificar cómo los Reales Decretos de enseñanzas mínimas de la educación obligatoria española relacionan la igualdad de género y la diversidad con el logro de los Objetivos del Desarrollo Sostenible (ODS). Para ello, este trabajo ha realizado un Análisis Documental empleando MAXQDA Analytics Pro 2024 de estos Reales Decretos. En el proceso de codificación se establecieron cinco familias: asignatura, elementos curriculares, igualdad de género, diversidad y factores de riesgo, diferenciando estos últimos en estructurales y en individuales. A su vez, se llevó a cabo un análisis lingüístico mediante el programa Sketch Engine para identificar las relaciones gramaticales y de los patrones lingüísticos de los dos conceptos que vertebran la investigación: diversidad y género. Los resultados muestran cómo la LOMLOE integra la perspectiva de género, aunque se centra en los factores individuales (ej. etnoculturales, corporales) sobre los estructurales, aunque las referencias a los ODS vinculados con la diversidad y el género son escasas. Como conclusión, la incorporación de la perspectiva interseccional a la educación obligatoria española permite visibilizar la opresión sufrida por colectivos vulnerables.

Culture has a core position and role in human life. This study aims to analyze the representation of Javanese culture through the character Jeng Yah in the novel Gadis Kretek by Ratih Kumala. The novel portrays the lives of Javanese people with traditional values such as politeness, local wisdom, strong spirituality, and the dilemma of preserving tradition. This study uses a qualitative descriptive approach, with data collected through reading and note-taking. The data collection procedure in this study follows the model developed by Miles and Huberman: (1) data collection, (2) selection to focus and refine the information, and (3) conclusion drawing. The study examines how the character Jeng Yah reflects social norms, communication ethics, and roles within Javanese culture. The results reveal that Jeng Yah not only represents Javanese women who uphold customs and manners but also shows an adaptation to social changes without losing her cultural identity. These findings illustrate that Javanese culture in this novel remains relevant and continues to evolve amidst modernization challenges while maintaining values that shape societal life. This journal is expected to provide new insights into how literature can play a role in reflecting and preserving local cultural values in the era of globalization.

Coral transplantation is the grafting or cutting of live coral to be grafted elsewhere or in places where the coral has been damaged, with the aim of restoring or forming natural coral reefs. Coral transplantation plays a role in accelerating the regeneration of damaged coral reefs, and can also be used to build new coral reef areas that did not previously exist. While the objectives of the study are: To describe the initial conditions, artificial coral transplantation in Tawara, at the Bunaken National Park location; Analyze the number of transplanted corals that survived for 7 years; Analyze the condition of transplanted corals by measuring the length and number of coral branches that survived for 7 years. Transplantation was carried out in 2018, after a year of measuring coral growth, namely in 2019. Data from the results of the study from 77 transplanted coral fragments, there were 3 dead coral modules, and those that survived were 74 coral fragments or 96% success in survival, while those that died were 4%.
Advanced Integration of Java EE Capabilities within CICS Liberty JVM Architecture
Authors:   Software Development Engineering - Sr Advisor 2, USA, Yalamanchili Chandra Mouli
Published: December 2024

With the introduction of Liberty JVM within CICS (Customer Information Control System), IBM has enabled the deployment and execution of modern
computing or APIs straight in CICS and executed them next to legacy applications written in COBOL, HLASM, and other languages. Using Java EE
features brings enterprise-level capabilities like scalability, transactionality, security, and manageability. This integration of Java EE features also enhances
the performance of Java applications deployed in CICS environments.
This paper explores different Java EE features, such as Context and Dependency Injection (CDI), Enterprise Java Beans (EJB), Java Persistence API (JPA),
Java Transaction API (JTA), Java Message Service (JMS), and more, available to Java applications deployed into the CICS Liberty JVM environment. It
also explores how the Liberty JVM supports each feature and how the integration with CICS works in each case.

Published: December 2024

Diabetic Retinopathy (DR) is a disorder of the eye and refers to the damage to the blood vessels of the retina as a result of high blood sugar levels in the body. This condition is the most common cause of blindness among working-age people. Vision impairment may result from DR and is regarded as a serious diabetes complication all over the globe. This paper evaluates the efficacy of two deep learning models, DenseNet-121 and ResNet-50, which have a widespread application in performing automated analysis of retinal images and detecting the presence of DR. DenseNet utilizes dense connectivity in order to efficiently reuse features, while ResNet uses residual connections to enhance the training of deep networks. The experiments were conducted on both models using an open-sourced DR dataset and their performance was evaluated with respect to accuracy, sensitivity, specificity and computational efficiency. The results of the analysis suggest that DenseNet is superior to ResNet in terms of accuracy and parameter efficiency, and therefore it is the best method in dealing with DR in a clinical setting. This information may assist the physicians in determining the appropriate models which should be employed for diabetic retinopathy detection in clinics.
