(Trans)languaging-for-learning: A perspective from the South
Authors: McKinney Carolyn , Tyler Robyn 
Published: October 2024

Background: While the concept of translanguaging has gained significant traction in education in multilingual contexts, it is also debated and contested. Claims are made about what translanguaging can and cannot do, how different it might be from code-switching, whether it arises from a single repertoire of language resources or from use of separate languages, and whether it is detrimental to or supportive of the development and inclusion of marginalised languages.Objectives: In this article we consider what these debates might mean in the South African context and how translanguaging might be different in South Africa with its particular racialised history of marginalisation of African languages. Drawing on epistemologies of the South, we align with the argument that there are multiple multilingualisms. We argue for (trans)languaging pedagogies that embrace both more fixed or monolingual uses of named languages as well as fluid, multilingual use of repertoires.Method: We will review early conceptualisations of translanguaging, showing how these are born out of different contexts as well as how translanguaging is taken up in South African research. We will draw on three examples of fixed and fluid pedagogical translanguaging to show what is possible within a South African classroom context.Results: The three examples show that (trans)languaging-for-learning goes beyond communicating bilingually in a classroom and involves planned meaning negotiation.Conclusion: In (trans)languaging-for-learning, the emphasis is on using one’s full linguistic and semiotic repertoire in order to develop and show understanding of learning, rather than to demonstrate mastery of the use of standard named languages.Contribution: The article expands translanguaging theory by theorising (trans)languaging-for-learning from a Southern perspective.
Performance improvement of microLED‐to‐microLED visible light communication using reverse bias
Authors: Kim Bo‐Guen , Kim Sung‐Man 
Published: October 2024

AbstractLED‐to‐LED visible light communication (VLC), which uses LEDs not only for the transmitter but also for the receiver, is being studied as an efficient optical wireless communication technology that uses LED lighting infrastructure. In this paper, we investigate microLED‐to‐LED VLC, which uses microLEDs as both the transmitter and receiver. In particular, we conducted a study to improve the performance of microLED‐to‐microLED VLC. For this, we measured the performance depending on the transmitter and receiver LED color combination. In addition, the effects of zero bias and reverse bias at the receiver LED were investigated. We also investigated the improvement in the reverse bias when applying a transimpedance amplifier to the receiver LED. Finally, we experimentally demonstrated a data rate of 360 kbps in the microLED‐to‐microLED VLC.

Published: October 2024

AbstractTo expand the scale of spiking neural networks (SNNs), an interface circuit that supports multiple SNN cores is essential. This circuit should be designed using an asynchronous approach to leverage characteristics of SNNs similar to those of the human brain. However, the absence of a global clock presents timing issues during implementation. Hence, we propose an intermediate latching template to establish asynchronous nonlinear connectivity with multipipeline processing between multiple SNN cores. We design arbitration and distribution blocks in the interface circuit based on the proposed template and fabricate an interface circuit that supports four SNN cores using a full‐custom approach in a 28‐nm CMOS (complementary metal–oxide–semiconductor) FDSOI (fully depleted silicon on insulator) process. The proposed template can enhance throughput in the interface circuit by up to 53% compared with the conventional asynchronous template. The interface circuit transmits spikes while consuming 1.7 and 3.7 pJ of power, supporting 606 and 59 Mevent/s in intrachip and interchip communications, respectively.

Published: October 2024

Besides being one of the causes of death in the world, adult congenital heart disease sufferers seem to be forgotten and neglected from what is called depression and anxiety. Not much has been described about depressive psychopathology in adult congenital heart disease patients. The purpose of this study was to analyze the factors associated with depressive syndrome in congenital heart disease patients. This cross-sectional study was conducted by 97 adult congenital heart disease patients recruited sequentially, consisting of 8 independent variables and 1 dependent variable. Depression scores were assessed using the BDI-II measuring instrument. Most sexes were female, with as many as 59 subjects (60.2 %). The most marital status was 66 subjects (67.3 %). The most occupations were those who worked as many as 70 subjects (71.4 %), the most previous history of surgery/intervention were those who did not have a history of prior surgery/intervention as many as 56 subjects (57.1 %), the most comorbid diseases were those who did not have a history of comorbid diseases as many as 86 subjects (87.8 %), age with a median value of 33 (18 - 45), the median value of education for adult CHD patients was 15 (12 - 18), the median NYHA grade value of adult CHD patients is 2 (1 - 4). The characteristics of patients who are highly educated, NYHA classmates, and who have jobs should be a concern because they will be more likely to experience depressive syndrome.
HIGHLIGHTS

Relationship between NYHA class and depression syndrome: Patients with higher NYHA grades are prone to depression. This indicates that the more severe the heart condition, the greater the level of depression.
The role of education in depression: The higher the education of heart patients, the more likely they are to develop depression.
Effect of work on depression: Patients without work are more prone to depression than patients who work, demonstrating the importance of job stability for inner well-being.
Use of BDI-II tool: Depression measurement is carried out using BDI-II, a screening tool that effectively measures depression.

Alpha(α)-mangostin (Xanthone of Garcinia mangostana L.): Augmenting Macrophages Activity for an Effective Diabetic Wound Healing
Authors: Patrick Melonney , Mohd Zohdi Wan Najwa Wan , Abd Muid Suhaila , Omar Effat 
Published: October 2024

Diabetic wounds are particularly difficult to treat medically because they heal at a slower pace than regular wounds. Macrophages are essential in all stages of normal wound healing, including inflammation, proliferation and rem odelling. When wound healing is affected, macrophages can reduce the level of growth factor and increase the level of interleukin-6 (IL-6), disrupt the balance between tissue inhibitors of metalloproteinase (TIMPs) and matrix metalloproteinase (MMPs), which can slow down healing. Alpha(α)-mangostin, a natural xanthone derived from the pericarp of the mangosteen, has gained considerable attention due to its anti-inflammatory properties, suggesting its potential to promote wound healing. However, its exact role in healing diabetic foot ulcers, common in diabetes, remains unclear. Hence, this study aims to explore how α-mangostin might affect diabetic wound healing by evaluating its impact on PDGF, CTGF, BFGF, VEGF, TGF-β, MMP-9, TIMP-2 and IL-6 secretion in macrophage cells. Human monocytic macrophages (THP-1) were incubated with a 35 mM glucose solution for 72 h to create a glucose-enriched medium. The cells were then incubated with α-mangostin (0.15, 2.5 and 5 µg/mL) together with 35 mM glucose. Carboxymethyl cellulose (CMC) served as positive controls; glucose-enriched media and media-alone served as negative controls. Protein expression was measured using ELISA. α-mangostin (2.5 µg/mL) increased the levels of PDGF and VEGF and decreased the level of MMP-9 compared to glucose controls. There was no significant difference in other growth factors, TIMP-2 and IL-6 protein levels across any of the treatment groups compared to glucose controls. In conclusion, α-mangostin particularly at 2.5 µg/mL demonstrated a significant increase in PDGF and VEGF levels while simultaneously reducing MMP-9 in macrophage cells under glucose-induced conditions. These findings suggest that α-mangostin holds the potential for enhancing the healing of chronic wounds in diabetic conditions.
HIGHLIGHTS

Treatment of macrophages (THP-1 cells) with 2.5 µg/mL Alpha (α)-mangostin in a high glucose medium led to a significant increase in PDGF and VEGF secretion compared to glucose control.
Treatment of the cells with 2.5 µg/mL Alpha (α)-mangostin in a high glucose medium led to a significant reduction of MMP-9 secretion compared to glucose control.
There is no significant effects of Alpha (α)-mangostin on IL-6 and TIMP secretion compared to controls
This study suggests that Alpha (α)-mangostin may be beneficial in promoting diabetic wound healing via stimulation of PDGF and VEGF secretion and reducing MMP-9 levels.

Primary dysmenorrhea (PD) is a prevalent problem in gynecology affecting the quality of life for young women. This medical condition is often responsible for the absence of young women from school or work, increasing the risk of developing hyperemesis gravidarum in the future. Furthermore, PD causes pain due to the activation of the local PGF2α pathway in the endometrium, which triggers oxidative stress processes, uterine ischemia and spasmodic uterine contractions. The first-line therapies for PD, Nonsteroid anti-inflammatory drugs (NSAIDs) and oral contraceptives, can cause side effects such as headache, nausea, intestinal ulcers and platelet abnormalities. To overcome the impact of PD, cupping has been proven effective as an alternative pain therapy with minimal side effects. Therefore, this study aimed to evaluate the effects of cupping on writing latency threshold time, PGF2α levels and FP receptor expression in PD model rats. The experiment was conducted using female Sprague Dawley rats to analyze the effects of wet cupping therapy (WCT) on inflammatory repair in the uterus. The method used was a pre- and post-test control group design, with 35 female rats randomly divided into 5 groups. These consisted of normal control (NC), negative control (C−), positive control (C+) + ibuprofen 7.2 mg, as well as treatment groups, comprising dry cupping (DC) and WCT. The results showed that writhing time threshold of WCT was the same as C+ (p = 0.368), while PGF2α decreased in DC (43.43 pg/mL, p = 0.008) and WCT (189.25 pg/mL, p = 0.0154). Similar to C+, WCT significantly decreased serum PGF2α levels compared to C−. WCT also influenced the expression of PTGFR subunit similarly to NC, showing the capacity to control the inflammatory pathway. The study suggested that WCT was a promising therapeutic strategy for PD by decreasing PGF2α and PTGFR expression.
HIGHLIGHTS
Previous investigations conducted on experimental animals using wet cupping therapy (WCT) have shown histopathological results associated with primary dysmenorrhea (PD) caused by estradiol benzoate and oxytocin. Moreover, this study shows the potential of WCT in reducing inflammation-induced PD pain by inhibiting the expression of PGF2α and PTGFR in the cyclooxygenase pathway, potentially increasing the pain threshold. The results show that WCT offers a potential alternative therapy for PD caused by estradiol benzoate and oxytocin.

Published: October 2024

This study addresses the challenge of processing undersized or overripe mangoes by integrating microwave heating with traditional foam-mat drying technique. The study aims at investigating drying kinetics coupled with thin-layer drying modeling and influences of microwave power (300 - 600 W) and hot-air temperature (55 - 75 °C). Among ten drying models, the so-called Midilli equation fitted well with experimental data. Results showed enhanced drying process associated with microwave heating, providing reduced drying time from 600 - 700 min (for conventional hot-air mode) to 30 - 100 min (for microwave-assisted mode). Standard deviations of moisture content and dried foam thickness measured at various points revealed uneven heat distribution when using high microwave energy, evidenced by burnt spots at 600 W. Additionally, foam collapse was observed under the mild process with low microwave powers, possibly due to prolonged drying periods. Response surface methodology demonstrated that microwave power was more important factor, positively affecting effective diffusivity coefficient (Deff) while inversely influencing specific energy consumption (SEC) and color difference (DE). Deff value increased from 5.41´10-6 m²×s-1 at 300 W and 55 °C to 18.43´10-6 m²×s-1 at 600 W and 75 °C, confirming enhance drying performance. As assisted with microwave heating, drying foamed mango sample consumed less energy up to 92 %. Optimal drying parameters were determined based on balancing the enhancement of drying performance and color alteration, suggesting drying the thick foamed mango pulp at temperature of 55 °C combined with microwave heating at 520 W, which can be served as a basis for further industrial scale-up.
HIGHLIGHTS

Novel method for thick mango pulp snacks.
Reduced drying time from 600 - 700 to 30 - 100 min.
Lowered energy use to 5.83 kWh×kg-1.
Optimal conditions at 520 W, 55 °C, desirability 0.669.
Applied Midilli model with 99 % accuracy.
