“I am able to have a different lens and different approach:” A Critical Examination of how Black Female Engineering Teachers Utilize and Create Counternarratives
Authors: Wright Christopher , Likely Rasheda , Allen-Handy Ayana , Flowers Alonzo
Published: June 2023

This research highlights the educational and professional experiences of three Black female secondary teachers of engineering. Using a lens of community cultural wealth, this research calls attention to the resources these teachers called upon during their navigation of engineering pathways and currently utilize to challenge their school’s normative perceptions of engineering and engineers. Findings of this work discuss how aspirational capital functioned to support the teachers’ successful matriculation through a STEM high school and undergraduate engineering and/or architecture programs, while also serving as a foundation for how they currently created opportunities for their students. Implications for future engineering education research and approaches for k-12 engineering educators acknowledging racialized and/or gendered experiences in these spaces are discussed.
Ain’t I A Woman: Black Women’s Endurance in Higher Education, the Implications of Linked Fate, and the Urgent Call for Greater Cultural Responsiveness
Authors: Butler Bettie R.
Published: June 2023

National data on Black women in higher education has typically been presented through a deficit lens. General interpretations have suggested that in ‘comparison’ to white women, the rate at which Black women enroll in college or secure faculty appointments is less than ideal. While this data is intended to highlight systemic inequities in opportunities for Black women in higher education, too often it is (mis)used to justify the intellectual inferiority of the group.  However, the same data—when examined through a critical lens—reveals something much more complex; which the present article attempts to unpack. Given the abounding obstacles Black women in academia experience due to the confluence of racism and sexism (and other interlocking systems of oppression), their perseverance, though painful at times, is rather remarkable and reason to pause and reflect; here’s why. Black women’s persistence is emblematic of our collective resistance to anti-Black structures, ideologies, and practices that are historically and deeply ingrained in institutions of higher education—namely, though not exclusively, predominately white institutions (PWIs). Beyond data points, Black women represent a collection of untold stories of struggle, advancement, and linked fate. When shared, stories provide strength, hope, and healing, and the courage to transform old systems and reimagine new academic spaces that recognize the humanity and value of Black women and their contributions to the academy. Given the importance of (counter)storytelling, the research highlighted within this current issue provides varied narrative and autoethnographic accounts of the lived experiences of Black women in higher education. Across each article are points for reflection and clear recommendations for action.  More implicit, but nonetheless present, is an urgent call for greater cultural responsiveness in higher education. A topic that is introduced and explored briefly here in this opening article.
“What Serves You”: Charting Black Girl Spaces for Wellness through Spirituality, Resistance, and Homeplace
Authors: Inniss-Thompson Misha , Butler-Barnes Sheretta , Taaffe Claudine , Elliott Taqiyyah
Published: June 2023

This qualitative study uses photovoice to illuminate 18 Black girls' (15 – 18 years old) descriptions and visualizations of mental health and wellness. Participants captured images of people, places, and symbols that represented being mentally healthy. Photos were used to elicit responses during semi-structured interviews. Data were analyzed using an iterative, flexible coding approach, which put the data in conversation with Black Girl Cartography, a conceptual framework highlighting the importance of places and spaces supporting Black girls. Our analyses suggest that participants defined mental health as dealing with emotions, feeling stable/at peace, coping with stressors, and being shaped by the external environment. Further, their wellness was facilitated by spirituality, resistance, and community. Findings suggest the intentional use of photography and participatory methodologies produce rich, grounded narratives that can contribute to a holistic understanding of Black girls' mental health and wellness.
Black Women Acting Against the Extremes of Visibility in the Academy
Authors: Roberts LaSonja , Nkrumah Tara , Migueliz Valcarlos Maria , Agosto Vonzell
Published: June 2023

Black women faculty building their academic lives can be treated as or made to feel invisible (i.e., ignored) or hypervisible (i.e., overly scrutinized). Subsequent harms can follow, such as stress, insecurity, power/voicelessness, and job attrition. Through the fusing of sister circles focus groups with Theatre of the Oppressed Forum Theatre, we explored how five Black women faculty confronted issues related to visibility utilizing this culturally informed critical arts-based methodology. Through introspection and performance, they brought in elder wisdom, and through rehearsal and performance, they left with shared knowledge on how to mediate at the extremes of visibility to improve their academic lives. We discuss the findings and their implications for academic healing via culturally responsive arts-based interventions and methodologies.

Published: June 2023

The study examined the digital self-efficacy and online learning readiness of pre-service teachers after the pandemic. Using a descriptive correlational research design, the results indicated that pre-service teachers have a high level of digital self-efficacy in several areas of technology integration, including digital usage, digital application, digital-infused learning, technology literacy, and digital-supported assessment. In addition, the results indicate that pre-service teachers are on the verge of being ready for online learning, though they still need to improve their time management and written communication skills. Age was found to be a significant factor in readiness for online learning, with those aged 25-34 demonstrating greater readiness than those aged 18-24 and 35-44. However, there was no significant difference when the participants were grouped by gender. These findings provide valuable insights into the digital self-efficacy and e-learning readiness of pre-service teachers, which can inform the development of strategies and interventions to improve their skills and, ultimately, enhance the quality of education in the post-pandemic world. Recommendations for digital education post-pandemic include providing training and resources for educators, supporting female teachers, incorporating online readiness training for pre-service teachers, tailoring programs to different age groups, and providing additional support for younger pre-service teachers to increase their digital self-efficacy.

Background and Objective- Surgical site infections are one of the most common cause of nosocomial infections and second most common cause of maternal mortality next to PPH. Surgical site infection being a relatively serious problem in our health institution, there are scanty published reports on the risk factors that are involved in SSIs in our local hospitals necessitatingfurther research to identify the indispensable factors responsible for high infection rate Methodology- Data were collected prospectively using predefined data collection forms which was developed after review of literature to identify risk factors for SSI. The form included patients demographic features, potential risk factors for SSI. A surveillance system as suggested by the CDC NHSN criteriawere used for diagnosing SSI. SSI was defined as a wound swab culture confirmed infection at the site of surgery within 30 days after an operation . SSI was defined as per NHSN criteria. Data was collected daily on all study participants after obtaining informed written consent, and followed them until discharge. The post discharge surveillance was done by actual patient visit in majority of patients (81%) or by mobile phones Results- Increasing age , increasing parity , anemia , hypertension , diabetes and poor nutrition, obesity were found to be independent risk factors for development of SSI. Conclusion- A proper assessment of identifiable risk factors that predisposes to SSI and their correction may help reduce SSI rates.

Histiocytosis is a rare systemic disease, with heterogeneous and diverse clinical and radiological presentations. Diagnosis can therefore be intriguing. Several consensus recommendations have emerged in recent years, particularly with the advent of targeted therapies, changing the management and prognosis. The authors present two cases of neurohistiocytosis. The case of Langerhans cell histiocytosis was about an adolescent with polyuria-polydipsic syndrome in whom a cerebellar biopsy was inconclusive. The patient was lost to follow-up for one year and then returned with a multisystemic neurological, bone, and dermatological presentation. The diagnosis was confirmed based on skin biopsy results. The patients condition rapidly deteriorated after chemotherapy with vinblastine and corticosteroids, leading to his death. The case of Erdheim-Chester disease was about a 53-year-old man who presented with cerebellar syndrome. His biological and radiological workup showed neurological, endocrine (diabetes insipidus) renal (hairy kidney), and bone (fibrosis) involvement. The diagnosis was confirmed by femoral biopsy and the patient was treated with Cladribine with an excellent evolution with an 18-month follow-up. This manuscript aims to report our personal experience and underline the entitys heterogeneity, non-specificity, and repercussions.

Authors: S. Suganthi , S. Birundha
Published: June 2023

The second-largest military force in the world, the Indian Defense sector, is on the verge of transformation. India is third in the world for military spending, with its defence spending making up 2.15% of the GDP of the nation. By 2025, GOI hopes to have a revenue of USD 25 billion, including an export of USD 5 billion in goods and services related to aerospace and defence. Two Defense Industrial Corridors have been developed by the government in Tamil Nadu and Uttar Pradesh. Defense Public Sector Undertakings (DPSUs) and Ordinance Factories (OFs) were gradually established to take on the role of designer and integrator of defence weapons and equipment under the purview of Department of Defence Production. Among 16 Defence Public Sector Undertakings (DPSU) the Hindustan Aeronautics Limited (HAL) is the largest DPSU and it tops the production with Rs.19911.5 crores in 2020 â€“ 2021 followed by Bharat Electronics Limited (BEL) of Rs.13947 crores to Indian Defense. In todays concern, we have competent DPSUs that are able to establish standards for the private sector in the manufacturing of defence goods because significant funds have already been invested in building competence in certain domains. Facilities, knowledge, and personnel developed by DPSU with public financing must be used to the best of the nations capacity as we move towards self-reliance and export capability in the acquisition of defence.

Periodontal disorders are a group of inflammatory conditions that induce degeneration of the Periodontium and damage the supporting components of the teeth, including gingiva, periodontal ligament, cementum, and alveolar bone, leading to tooth loss. According to WHO, approximately 10-15% of the worlds population suffers from severe periodontal diseases. Periodontal disease pathophysiology is linked to microbial biofilm development,dental plaque, and host cell immunogenicity. The severity of this condition is determined by risk factors and stage of development. Low-Level Laser Therapy (LLLT) is a light source treatment that generates light of a single wavelength. The low-level lasers do not cause temperature elevation within the tissue, but rather produce their effects from photo bio stimulation effect within the tissues.Low-level laser is capable of reducing inflammation and appearance of MMP8 (Matrix Metallopeptidase8) following scaling. LLLT apart from pain reduction is also known to help in repair process and thus subsequently accelerating the wound-healing process. The primary goal of this article is to offer a holistic update on periodontal disease in terms of its occurrence ,stages, pathogenesis, diagnosis, therapy, and management.

Published: June 2023

The COVID-19 pandemic since March 2020 has forced Indonesians to practice physical distancing and carry out their personal and professional activities from home. However, not everyone is ready to conduct their regular activities remotely. The issue is the readiness for digital technology. The research aims to analyze the Indonesian people’s readiness for digital technology during the pandemic. The research also investigates the impact of optimism and technology adoption on behavioral intention mediated by perceived ease of use. The research applies a quantitative study using an online questionnaire. The population of the research is people who use Internet technology for online learning, working from home, online shopping, and social activities during the COVID-19 pandemic. The research successfully gathered 327 respondents using purposive sampling. The research uses Structural Equation Model (SEM) method via SPSS AMOS software to analyze the data and generate findings. There are several findings. First, optimism has a positive relationship with perceived ease of use. Second, technology adoption relates with perceived ease of use positively. Third, perceived ease of use has a positive relationship with behavioral intention. Last, the empirical evidence for the mediation roles of perceived ease of use is inconclusive. The research also offers some managerial implications.
Relações de gênero e sexualidade: Uma análise do discurso dos livros didáticos
Authors: Gimenes Garcia Ronaldo Aurélio , De Barros Cristina Terezinha Borges
Published: June 2023

O livro didático é, muitas vezes, a única referência para o trabalho dos educadores, assumindo um papel central nas definições de estratégias de ensino. Além de interferir na organização pedagógica das escolas, tem peso na cultura dos cidadãos, por influenciar nos valores das sociedades, pela forma que apresenta os fatos e pelo próprio processo de veiculação do conhecimento. Em virtude de seu frequente uso nas instituições escolares, se faz necessário averiguar como e de que forma são abordadas as questões de gênero e sexualidade nos livros didáticos. Neste trabalho, procuramos identificar se os livros em circulação estão livres de preconceitos e estereotipagem. Para tal, a metodologia utilizada foi a de ATD (Análise Textual Discursiva). Foram examinados os livros didáticos do oitavo ano do Ensino Fundamental de uma escola do Sudoeste do Estado do Paraná. É possível argumentar que alguns dos livros analisados deixam a desejar na abordagem dos temas transversais gênero e sexualidade, e que os mesmos ainda contêm informações equivocadas e desatualizadas, predominando uma visão heteronormativa.

Authors: Lee Kyung Suk , Shin Jae Bong , Kim Jun Sik , Do Gi Cheol , Kim Min Hyung , Kim Nam Gyun
Published: June 2023

Angiosarcoma is a very rare subtype of sarcoma. It mainly occurs in the head and neck, and cutaneous angiosarcoma in this region seems to be a distinctive neoplasm with characteristic clinicopathologic features that differ from those of angiosarcoma in other anatomical locations. The prognosis of angiosarcoma in the head and neck region is poor, and the risk of local recurrence and metastasis is high. We reconstructed an atypical angiosarcoma that presented as a solitary nodule with a shape suggestive of hemangioma on the cheek using a modified bilobed local flap. At a 12-month follow-up visit, the patient in this case showed successful recovery after radiation therapy.

Published: June 2023

La producción de tomate mini en invernadero ha aumentado en las últimas décadas, sin embargo, el uso eficiente de los fertilizantes y el efecto en la calidad de los frutos, con frecuencia se pasan por alto. En este trabajo se determinaron los rangos de concentración iónica, así como la relación entre los iones (NO3-, K+, Ca2+, y Na+), el pH, conductividad eléctrica de la solución nutritiva, los sólidos totales solubles (TSS) del extracto celular de peciolo (PCE) y el extracto celular de fruto (FCE) en tomates mini (Grape, Savantas, y Tov) en el ciclo verano-invierno. Se registraron altos rangos de concentración iónica. El Na+ y K+ colectados en los emisores, mostraron fuerte correlación con los mismos iones registrados en el PCE. El mapa de calor de las correlaciones mostró agrupaciones entre el K+ y Ca2+ de la solución nutritiva, los cuales se encontraron en alta correlación con el contenido en PCE y FCE en la temporada de invierno. El análisis de componentes principales mostró que el NO3- y Na+ distan del contenido de K+ y Ca2+ del PCE y FCE. Los rangos de concentración encontrados, sugieren suficiencia iónica para los genotipos de tomate mini producidos en invernadero de alta tecnología.

Authors: Osorio González Rebeca , Jaimes Garrido Rosa Isabel , Castro Ricalde Diana
Published: June 2023

El propósito de este artículo es realizar un análisis desde la perspectiva feminista sobre los significados de la visita turística en cuatro espacios geográficos de México. Se hará uso de la propuesta conceptual del espacio público y privado postulada por las autoras Celia Amorós, Michelle Rosaldo y Consuelo Banda Cárcamo, con el fin de explicar cómo social, cultural e históricamente se ha construido la idea de tales espacios y comprender la importancia de la apropiación del espacio público turístico por parte de las mujeres. Para ello, se plantearán preguntas como: ¿qué consideraciones hacen las mujeres al momento de visitar o no un lugar turístico?, ¿qué percepciones tienen sobre los lugares visitados?, ¿cómo se apropian de ellos? Se aplicó un enfoque mixto de investigación a través de técnicas de entrevista en profundidad y la aplicación de cuestionarios de encuesta, basados en cinco categorías de análisis: diversión-recreación, pernocta, traslados, gastronomía y acompañantes. Entre los principales resultados, se identifica que existe una percepción de inseguridad en algunos espacios públicos, y que predominan lugares y horarios exclusivos para hombres.
Trophic status estimation of case-2 water bodies of the Godavari River basin using satellite imagery and artificial neural network (ANN)

Published: June 2023

The dynamics of trophic status estimation of case-2 water bodies on a synoptic mode for frequent intervals is essential for water quality management. The present study attempts to develop trophic status estimation approaches utilizing Landsat-8 and Sentinel-2 images as inputs. The chlorophyll-a concentration, a proxy parameter for trophic status, was estimated using the empirical method, fluorescence line height (FLH) method, and artificial neural network (ANN) approaches using spectral reflectance values as inputs. The outcomes following the empirical approaches revealed the scope of kernel normalized difference vegetation index (kNDVI) (R2 = 0.85; RMSE = 2 μg/l) for estimating the chlorophyll-a concentration using Sentinel-2 images of the Godavari River basin. Though the performance of the FLH method (R2 = 0.91; RMSE = 1.6 μg/l) was superior to kNDVI-based estimation, it lacks the capability to estimate chlorophyll-a concentration above 20 μg/l. Due to the existence of eutrophic regions within the Godavari basin (28%), adopting better approaches like ANN for trophic status estimation is essential. To accomplish the same, the Levenberg–Marquardt algorithm-based ANN was developed using non-redundant bands of Sentinel-2 as inputs, and Sentinel-3 derived chlorophyll-a values as output. The developed architecture was successful in estimating trophic status estimations at all levels.
Toward establishing a knowledge graph for drought disaster based on ontology design and named entity recognition
Authors: Fang Yihui , Zhang Dejian , Wu Guoxiang
Published: June 2023

Drought disasters have caused serious impacts on the social economy and ecological environment, which are continuously and increasingly exacerbated by climate warming and other factors. Drought disaster management usually involves processing a mass of isolated data from many fields expressed in different terminologies and formats. These heterogeneous data or so-called data silos have greatly hindered drought disaster management in an information-rich manner. Establishing a drought disaster knowledge graph can facilitate the reuse of these heterogeneous data and provide references for drought disaster management, and ontology design and named entity recognition are the two major challenges. Therefore, in this study, we first designed a drought disaster ontology by recognizing the major concepts in the drought disaster field and their relationships, which was implemented with an ontology modeling language. We next constructed a drought disaster corpus and an integrated entity recognition model that was built by integrating multiple deep learning methods. Finally, we applied the integrated entity recognition model to extract information from the CNKI literature database. The integrated model shows satisfactory results in drought disaster named entity recognition. We thus conclude that combining ontology and deep learning technology toward establishing a knowledge graph for drought disasters is promising.

Published: June 2023

Background:

Trichobezoar is a condition characterized by the accumulation of undigested hair and or other foreign bodies in the stomach. The reported occurrence is uncommon in the Middle East and usually affects female adolescents and young children. Rapunzel syndrome, which almost exclusively affects young women, is a rare form of trichobezoar in the stomach that spreads to the intestine and is associated with psychiatric disorders such as trichotillomania and trichophagia

Case Presentation:

This report describes a rare case of giant trichobezoar complicated with acute pancreatitis in a young patient which was ultimately treated with the removal of trichobezoar by surgical gastrotomy.

Conclusion:

Trichobezoar is an underdiagnosed and rare disease that should be addressed in adolescents with trichotillomania and trichophagia with delicate clinical symptoms, especially in females. Endoscopy can help with a definitive diagnosis and surgery remains the gold standard for the treatment of this condition.
Atorvastatin Calcium Ameliorates Cognitive Deficits Through the AMPK/Mtor Pathway in Rats with Vascular Dementia

Published: June 2023

Aim:

In this study, the protective effects of atorvastatin calcium (AC) on nerve cells and
cognitive improvement in vivo and in vitro were investigated by establishing cell models and vascular
dementia (VD) rat models.

Background:

VD is a neurodegenerative disease characterized by cognitive deficits caused by
chronic cerebral hypoperfusion. AC has been studied for its potential to cure VD but its efficacy
and underlying mechanism are still unclear.

Objective:

The mechanism of action of AC on cognitive deficits in the early stages of VD is unclear.
Here, the 2-vessel occlusion (2-VO) model in vivo and the hypoxia/reoxygenation (H/R) cell
model in vitro was established to investigate the function of AC in VD.

Methods:

The spatial learning and memory abilities of rats were detected by the Morris method.
The IL-6, tumour necrosis factor-α (TNF-α), malondialdehyde (MDA) and superoxide dismutase
(SOD) in cell supernatant was tested by ELISA kits. After behavioural experiments, rats were
anaesthetized and sacrificed, and their brains were extracted. One part was immediately fixed in
4% paraformaldehyde for H&E, Nissl, and immunohistochemical analyses, and the other was
stored in liquid nitrogen. All data were shown as mean ± SD. Statistical comparison between the
two groups was performed by Student’s t-test. A two-way ANOVA test using GraphPad Prism 7
was applied for escape latency analysis and the swimming speed test. The difference was considered
statistically significant at p < 0.05.

Results:

AC decreased apoptosis, increased autophagy, and alleviated oxidative stress in primary
hippocampal neurons. AC regulated autophagy-related proteins in vitro by western blotting. VD
mice improved cognitively in the Morris water maze. Spatial probing tests showed that VD animals
administered AC had considerably longer swimming times to the platform than VD rats.
H&E and Nissl staining showed that AC reduces neuronal damage in VD rats. Western blot and
qRT-PCR indicated that AC in VD rats inhibited Bax and promoted LC3-II, Beclin-1, and Bcl-2 in
the hippocampus region. AC also improves cognition via the AMPK/mTOR pathway.

Conclusion:

This study found that AC may relieve learning and memory deficits as well as neuronal
damage in VD rats by changing the expression of apoptosis/autophagy-related genes and activating
the AMPK/mTOR signalling pathway in neurons.
Wikstroemia: A Review on its Phytochemistry and Pharmacology
Authors: Huan Duong Quang , Hop Nguyen Quang , The Son Ninh
Published: June 2023

Background:

Wikstroemia (the family Thymelaeaceae) consists of medicinal plants
which established great value in traditional medicines for many years. For instance, W. indica is
always recommended for treatments of syphilis, arthritis, whooping cough, and cancer. No systematic
review of bioactive compounds from this genus has been recorded to date.

Objective:

The objective of the current study is to review phytochemical investigations and
pharmacological effects of Wikstroemia plant extracts and isolates

Methods:

By searching on the internet, the relevant data about Wikstroemia medicinal plants were
retrieved from internationally renowned scientific databases, such as Web of Science, Google
Scholar, Sci-Finder, Pubmed, and so on.

Results:

More than 290 structurally diverse metabolites were separated and identified from this
genus. They include terpenoids, lignans, flavonoids, coumarins, mono-phenols, diarylpentanoids,
fatty acids, phytosterols, anthraquinones, and others. Pharmacological records indicated that Wikstroemia
plant crude extracts and their isolated compounds bring out various beneficial effects,
such as anticancer, antiinflammatory, anti-aging, anti-viral, antimicrobacterial, antimalarial, neuroprotective,
and hepatoprotective activities.

Conclusion:

Wikstroemia has been regarded as a worthy genus with numerous phytochemicals
and various pharmacological potentials. Modern pharmacological studies have successfully provided
evidence for traditional uses. Nonetheless, their action mechanisms need to be further investigated.
Although various secondary metabolites were identified from Wikstroemia plants, the
current pharmacological research mainly concentrated on terpenoids, lignans, flavonoids, and
coumarins.
Improved Bioavailability and Hepatoprotective Activity of Baicalein Via a
Self-assembled Solutol HS15 Micelles System
Authors: Zhang Shuna , Wang Ying , Shan Jiaojiao , Qi Xueju , Liu Qun
Published: June 2023

Background:

Baicalein (BA) is a flavonoid extract from the root of Scutellaria baicalensis
Georgi with excellent biological activities, such as antioxidant and anti-inflammatory activities. However,
its poor water solubility limits its further development.

Objective:

This study aims to prepare BA-loaded Solutol HS15 (HS15-BA) micelles, evaluate the bioavailability,
and explore protective effects on carbon tetrachloride (CCl4) induced acute liver injury.

Methods:

The thin-film dispersion method was used to prepare HS15-BA micelles. The physicochemical,
in vitro release, pharmacokinetics, and hepatoprotective effects of HS15-BA micelles were studied.

Results:

The optimal formulation showed a spherical shape by characterization of the transmission electron
microscope (TEM) with an average small size (12.50 nm). The pharmacokinetic results illustrated
that HS15-BA increased the oral bioavailability of BA. The in vivo results showed that HS15-BA micelles
significantly inhibited the activity of the CCl4-induced liver injury marker enzymes aspartate
transaminase (AST) and alanine transaminase (ALT). Also, CCl4 induced oxidative damage to liver
tissue, leading to increased L-glutathione (GSH) and superoxide dismutase (SOD) activity and decreased
malondialdehyde (MDA) activity, while HS15-BA significantly reversed the above changes.
Moreover, BA also had a hepatoprotective effect through anti-inflammatory activity; the results of ELISA
and RT-PCR revealed that HS15-BA pretreatment significantly inhibited the increase in the expression
of inflammatory factors induced by CCl4.

Conclusion:

In summary, our study confirmed that HS15-BA micelles enhanced the bioavailability of
BA, and showed hepatoprotective effects through antioxidant and anti-inflammatory activities. HS15
could be considered a promising oral delivery carrier in treating liver disease.
