Authors: Loho Imelda Maria , Siregar Lianda , Iriani Dewi , Faatinah Tiyas Hasnaa
Published: May 2024

Patients with metastatic cervical cancer, particularly hematogenous metastasis, have a worse prognosis compared to those with localized cervical cancer. Gastrointestinal involvement of cervical cancer occurs in approximately 8% of cases and most lesions are located in the recto-sigmoid area due to direct extension of the disease. Here, we present a case of cervical adenocarcinoma spreading to the ascending colon as a sessile polyp and mimicking a hyperplastic polyp. Histopathological evaluation followed by immunohistochemistry analysis is needed to confirm the diagnosis.

Published: May 2024

The relationship between teacher trainees' sense of belonging and educational outputs is a crucial aspect of academic success. While we vouch that several studies have been conducted on this topic, the majority of these studies are carried out in higher education (universities) and developed countries. Sparse literature exists on teacher training colleges in emerging economies. This is the backdrop against which this research was conducted. Utilizing the correlational research design and surveys of 522 respondents, the study examined the relationship between teacher trainees' sense of belonging and educational outputs, using colleges of education of Volti Zone in Ghana as case studies. Findings revealed that there is a statistically significant relationship between a sense of belonging and educational outputs of GPA (R = .648, p = .003); students' engagement (R = .191, p = .000); retention (R= .718, p = .016); and persistence (R = .423, p = .035). The study concludes that students' perception of a sense of belonging on college campuses is positively correlated with educational outputs at a 95% confidence level. Understanding and nurturing this connection holds the potential to enhance overall educational efficacy and contribute to a more inclusive and supportive learning environment.

The Role of Fashion Illustration as a Communicative Tool in Design
Authors: James Tetteh Ademtsu  , Rita Esinam Tsenuekpor Tetteh  , Sheila Naa Tetteorkor Clottey
Published: May 2024

This qualitative study investigates fashion illustration's role as a conceptual communication tool within Ghana's developing design education landscape through interviewing 5 fashion lecturers and 10 undergraduate students. The thematic analysis uncovers multifaceted pedagogical and socio-cultural functions of illustration in nurturing students' cultural visual literacies, critical perspectives, and creative confidence during early design stages. Perspectives highlight persistent challenges balancing mainstream global aesthetics and meaningful representations of local cultural traditions and identities across the curriculum. Findings provide empirically grounded, localized insights on leveraging this visual medium to bridge modernity and tradition at the intersection of Ghana's emerging formal fashion infrastructures and dynamic transnational design flows. Foregrounding Ghanaian voices shape the understanding of how hybridity manifests through selectively integrating foreign illustration techniques to nurture local relevance. Interpretations posit illustration's capacity to strengthen pluralistic communication and identity expression anchored in indigenous visual culture yet resonating globally. This exploratory study constitutes an early step toward decolonizing African design pedagogies by elevating Ghanaian standpoints and creative-educational priorities to enrich conceptual communication functionality. Wider survey and comparative research can further generalize and contextualize findings toward this long-term goal.

Published: May 2024

The study examined an analysis of the effect of climate change adaptation measures used by cassava farmers in a central agricultural zone, Cross River State, Nigeria. A systematic sampling technique was used to select 141 Cassava farmers who participated in the study. Data collected were analyzed using descriptive statistics and a logit model. Adaptation measures and barriers to adaptation were captured using a four (4) point Likert scale, while the data on socio-economic characteristics were analyzed using descriptive statistics such as percentage and frequency, while hypothesis one was tested using a logit regression model and hypothesis two was tested using Chi-square x2. The findings show that (74.80/0) of the respondents were between the ages of 31 years and above. The majority of the respondents were males (50.10/0), while 480/0 of them were females and were mainly dominated by the married class (50.30/0). The study reveals that the major cause of climate change in the study area is bush burning, which was ranked first; using agricultural chemicals was ranked second; and deforestation was ranked third, respectively. While the climate change effects were reducing rainfall, was ranked first pest and disease outbreaks and drought were ranked second and third, respectively, as the most adverse effects caused by climate change in the study area. The study also shows that farmers have been able to carry out some adaptation measures to combat the effect of climate change, such as the use of improved cassava varieties, the use of green manure, early planting, change of planting date, change of harvesting date and tillage. It was also revealed that the barriers associated with climate change mitigation include lack of access to weather forecast technology, inadequate finance to cope with the changing climate, and lack of cassava varieties that are adaptable to low rainfall. The result of the Chi-square x2 test on the relationship between the effect of climate change and the adaptive measures used by cassava farmers in the study area shows that x2 values of 287.3 of the effect of climate change on cassava production are greater than the tabulated value of 0.0922. The result, therefore, indicates that there is a significant relationship between the effect of climate change and the adaptive measures used by cassava farmers. The positive sign associated with the variables in the logit regression model improved varieties of cassava stem, green manure, early planting, and mulching would increase cassava yield. It was recommended that policy-makers formulate policies that will strengthen climate adaptation in the study area.

Published: May 2024

This study examines human interaction with artificial intelligence technology, focusing on the implementation of ChatGPT, a chatbot developed by OpenAI. Through the Human-Machine Communication (HMC) approach, the research describes human-like attributes in ChatGPT, exploring emotional responses and utility in educational, professional, and personal contexts. Qualitative research methods with triangulation techniques were used for a holistic understanding, involving interviews, observations, and document analysis. The results indicate that ChatGPT can provide adaptive responses, adjusting language style, and presenting information with self-awareness. Comparisons between human-to-human and human-to-machine interactions, particularly through ChatGPT, reveal significant differences. In human-to-human communication, the primary role is given to humans as message sources, while in machine communication, ChatGPT becomes an interactive partner, especially in text messages. Despite similarities in interpersonal communication features, such as feedback, personal relationship cues are more pronounced in human-to-human interactions. Factors like self-concept, openness, and confidence are dominant in human-to-human communication, while AI literacy becomes crucial in interactions with machines.

Sexual Objectification of Girls in Anime Series: Sara Mills’ Critical Discourse Analysis
Authors: Hutagalung Sandra , Maryani Eni , Setiaman Agus
Published: May 2024

The "sex sells" marketing strategy is still used by anime, a form of entertainment that is becoming more and more popular worldwide, and one of them is Mushoku Tensei: Isekai Ittara Honki Dasu anime series. Due to the main character's vulgarity against girls, this anime series sparked debate among anime viewers. For a number of reasons, such as the freedom to work for artists and the fact that sexual objectification done through animation does not damage real girls, objections to this topic are frequently refuted. The goal of this study is to identify the various ways that girls are sexually objectified in anime, which could affect viewers' attitudes and actions. A qualitative approach is used through critical discourse analysis by Sara Mills. Discourse is utilized methodologically to dismantle forms of sexual objectification of women in anime series. It is revealed how women are portrayed as sexual objects in anime fan service through the male gaze through discourse analysis of characters, focalization, fragmentation, and cinema schemata. Findings from this study indicate that there existed instances of sexual objectification of women in the anime series Mushoku Tensei: Isekai Ittara Honki Dasu, particularly in relation to the love interest of the main male character. This study critically makes us aware that the growth of digital media, which can provide a wide range of content and depict a variety of male and female characters, nevertheless reinforces patriarchal value. Even in the digital age, animation—a creative form of entertainment—continues to treat girls as just objects of desire for men. This serves as a reminder that the conventional entertainment industry, which frequently makes fun of sexual harassment of women, still exists in the internet sphere. In light of this anime series, women participation in the digital sphere ought to be promoted in order to change people's perceptions of women. It has been proven that the freedom that many advocate in the digital age yet imposes restrictions on the presence of girls as a subject. Keywords: anime; digital; girls; objectification; male gaze;

Published: May 2024

Исследуется структура пограничного слоя на плоской поверхности в условиях посадки на Марс. Вводится двухтемпературная модель колебательно возбужденной диссоциирующей трехкомпонентной газовой смеси CO2, CO, O, позволяющая адекватно воспроизвести основные характеристики гиперзвукового полета в атмосфере Марса. Для двух точек траектории посадки на Марс выполнены расчеты плоского пограничного слоя на пластине с изотермической некаталитической поверхностью. Выполнено сравнение профилей газодинамических величин, рассчитанных на основе локально автомодельных уравнений с профилями, полученными конечно-разностным методом на основе полных уравнений пограничного слоя. Показано, что с точностью, приемлемой для последующих расчетов устойчивости, имеет место выход профилей, полученных из полных уравнений, на локально автомодельные решения. Проведено сравнение фазовых скоростей нейтральных (растущих) возмущений, вычисленных на основе известного критерия обобщенной точки перегиба и соответствующего обобщения, явно учитывающего условия развитой диссоциации.

The structure of the boundary layer on a ѕat surface under conditions of landing on Mars is studied. A two-temperature model of a vibrationally excited dissociating three-component gas comprising of CO2, CO and O mixture is introduced, which allows adequately reproducing the main characteristics of hypersonic ѕight in the Martian atmosphere. For two points of the landing trajectory on Mars, calculations of a ѕat boundary layer on a plate with an isothermal non- catalytic surface were performed. The profiles of gas-dynamic quantities obtained on the basis of locally self-similar equations are compared with the profiles obtained by the finite-difference method based on the complete equations of the boundary layer. It is shown that, with acceptable accuracy for subsequent stability calculations, the profiles obtained from the complete equations yield locally self-similar solutions. A comparison is made of the phase velocities of neutral (growing) perturbations obtained on the basis of the well-known criterion of the generalized inѕection point and the corresponding generalization, which explicitly takes into account the conditions of developed dissociation.

Published: May 2024

Workflow managers play a critical role in the efficient planning and execution of complex workloads. A handful of these already exist within the world of computational materials discovery, but their dynamic capabilities are somewhat lacking. The PerQueue workflow manager is the answer to this need. By utilizing modular and dynamic building blocks to define a workflow explicitly before starting, PerQueue can give a better overview of the workflow while allowing full flexibility and high dynamism. To exemplify its usage, we present four use cases at different scales within computational materials discovery. These encapsulate high-throughput screening with Density Functional Theory, using active learning to train a Machine-Learning Interatomic Potential with Molecular Dynamics and reusing this potential for kinetic Monte Carlo simulations of extended systems. Lastly, it is used for an active- learning-accelerated image segmentation procedure with a human-in-the-loop.
Statistical Mechanics of Kevlar® KM2® Plus Nanostructure: Deformations and High-Rate Impact
Authors: Ploch Michael , Roenbeck Michael , Pretko Jacob , Seay Christopher , Strawhecker Kenneth , Lustig Steven
Published: May 2024

A detailed understanding of all phenomena that determine high-rate impact response of woven polyaramid systems is needed to design more effective materials and save lives. This study investigates the detailed nanostructures of Kevlar® KM2® Plus fibers from woven systems subjected to controlled rheometric deformations and high-rate impact. The rheometric tension, axial compression following tensile failure, and transverse compression are basic deformations not previously studied by our methods and hypothesized in high-rate impact. The impact of a high-rate object causes significant, layer-dependent nanostructural changes to woven systems. Multichannel AM-FM atomic force microscopy characterizes interior fiber nanostructure with spatially-resolved topological and viscoelastic property measurements of pleat lengths, crystal misorientation angles, fibril widths, and void widths. Statistical analyses were developed to assess convergence of nanostructure feature measurement distributions and compare the correlated nanostructure feature distributions between samples. The data and analyses indicate that tension is not the only mechanism of energy transfer from the impact of a high-rate object and that compressions, both in the axial and transverse directions, are also significant. The varying localized responses to high-rate impact and the presence of both tension and compression imply better systems can be created by improving tensile and compressive properties, tailoring fabric layers to perform to specific types of mechanical deformations.

Authors: Kuehl Silke , Freeland Abigail , Stanley James , Cunningham Ruth
Published: May 2024

aim: Mental health-related emergency department (ED) presentations are steadily increasing, including presentations for both mental health and non-mental health concerns by existing clients of mental health services. The study aim was to examine and compare mental health clients and non-clients’ ED presentations, identify data and clinical gaps and make recommendations for improvement. method: De-identified 2017/2018 ED data were used to describe presentations for current and recent (within last 5 years) clients of specialist public mental health and addiction services, compared to presentations of non-mental health clients. results: Of 49,170 presentations, 18% were by clients of mental health services. Compared to other ED presenters, mental health clients were often younger, female and Māori, required more urgent care and waited longer. Mental health-related International Classification of Diseases (ICD) codes/referrals were most common for presentations by current mental health clients, whereas pain and trauma were often the reason for prior mental health clients’ presentations. Discharge diagnoses rarely included self-harm behaviour, and admissions for these clients were more commonly by ED rather than mental health services. conclusion: Mental health clients are common in ED. Enhanced mental health data capture and improved systems and processes are needed to ensure that ED staff can better meet their often-complex needs.

Published: May 2024

Background: Methotrexate is a highly effective systemic treatment for moderate to severe psoriasis, but drug toxicity may limit its use. Recent evidence suggests that it is necessary to take into account the individual characteristics of methotrexate pharmacokinetics, which are determined by the presence of polymorphisms of genes encoding methotrexate carrier proteins, to predict the risk of methotrexate-induced toxicity. Aim: The research aims to assess the associations of ABCB1 rs1045642 (3435C>T) polymorphism with methotrexate safety for patients with moderate and severe psoriasis. Methods: The study included 75 psoriasis patients treated with methotrexate with 21 days of follow-up duration. Data on adverse drug reactions (ADR) were collected using a clinically structured questionnaire, and complete and biochemical blood tests, and urinalysis were performed. The severity of ADR was assessed using visual analog scales and the CTCAE toxicity scale. The severity of gastrointestinal ADR was assessed using the GSRS questionnaire. Genotyping was carried out by real-time PCR. Results: Gastrointestinal toxicity was detected in 38 patients (50.67%). The mean GSRS score was 7.97 ± 9.18. Analysis of differences in the ADR incidence showed the presence of statistically significant differences in the frequency of ADR in the gastrointestinal tract: the toxic effect of methotrexate was more often observed in carriers of the T allele of the ABCB1 rs1045642 polymorphism (3435C>T), (CC: 2 (14.3%), TC: 18 (52.9%), TT: 18 (66.7%), P = 0.006). Binomial regression demonstrated the presence of a statistically significant effect of the rs1045642 single-nucleotide polymorphism of the ABCB1 gene on the incidence of ADR from the gastrointestinal tract (OR = 8.64, P = 0.008). Conclusion: An association of ABCB1 rs1045642 single-nucleotide polymorphism with the safety of methotrexate therapy in patients with moderate and severe psoriasis was revealed. The data obtained can be used to personalize the prescription of methotrexate to psoriasis patients.

Objective: To investigate the clinical efficacy of intense pulsed light combined with doxycycline in the treatment of rosacea. Methods: A sample of 60 patients with rosacea admitted to our hospital from January 2021 to December 2023 were selected and grouped into the observation group (n = 30) and the control group (n = 30) by using the randomized numerical table sampling method. The patients in the control group were treated with doxycycline, and the patients in the observation group were treated with intense pulsed light combined with doxycycline. The clinical effective rate and recurrence rate, clinical symptom score, skin barrier function indexes, and the incidence of adverse reactions in the two groups were compared. Results: The clinical effective rate of the observation group was higher than that of the control group, and the recurrence rate was lower than that of the control group (P < 0.05); the clinical symptom score of the observation group was lower than that of the control group after treatment (P < 0.05); the water content of the stratum corneum of the observation group was higher than that of the control group after treatment, and the amount of transepidermal water loss was lower than that of the control group (P < 0.05); the incidence of adverse reactions of the two groups did not have any significant difference in comparison (P > 0.05). Conclusion: The treatment effect of intense pulsed light combined with doxycycline in rosacea patients is remarkable. It can alleviate clinical symptoms and improve the skin barrier function, with a lower recurrence rate after treatment and higher therapeutic safety, which is suitable for popularization and use in healthcare institutions.

Published: May 2024

Listening is the primary method to access language information. It is an essential part of L2 (second language) teaching but also the most difficult skill to master for L2 learners. Based on this, it is necessary to analyze learners’ needs in listening. This article aims to conduct a needs analysis of a selected learner from Iraq and describe course material selection and design. Methods including questionnaires, interviews, and observation were used to collect data. Additionally, targeted 60-minute online listening activities were designed. It was found that listening activities can improve both listening and speaking skills. Thus, language teaching should be student-oriented, and subsequent course materials and activity design should be selected based on the analysis of students’ needs.
