Central bank intervention and exchange rate volatility in the inflation-targeting regime
No full textThis paper examines the impact of central bank intervention on the exchange rate fluctuations within the framework of inflation-targeting. Focusing on Indonesia, the Philippines, and Thailand from 2005(7) to 2022(12), empirical analysis using quantile regression demonstrates that the central bank intervention mitigates real exchange rate volatility. However, there is a discernible upward linear trend in the coefficient related to market intervention. While overall behavior tends to be symmetrical, selling intervention and interventions during depreciation periods differently affect real exchange rate volatility across quantiles. Those results underline the importance for monetary authorities to consider shifts in exchange rate expectations over the medium term. Accordingly, the selective implementation of market intervention, tailored to the dynamics of real exchange rate volatility, is essential for upholding the credibility of inflation-targeting monetary policy

The proliferation of MDA-MB-231 cells is repressed by mesenchymal stem cell-mediated macrophage activation conditioned medium through the inhibition of AKT1 and YKL-39 genes
No full textBackground: Triple-negative breast cancer (TNBC) is characterized by a substantial presence of tumor-associated macrophages (TAMs) exhibiting an M2-like phenotype, which plays a crucial role in promoting tumor cell stemness and invasiveness. Mesenchymal stem cells (MSCs) have the ability to induce the transformation of naive macrophages (M0) into M1-like macrophages. This study delves into the interplay between MSCs and macrophages within the context of breast cancer (BC) progression using a TNBC cell line, as reprogramming of TAMs into M1-like macrophages may emerge as a promising therapeutic strategy for BC. Methods: THP-1 cells were induced into M0 macrophages and co-cultured with UC-MSCs, subsequently analyzing CM for M1- and M2-type macrophage-related cytokines. Total RNA from co-cultured cells was used to assess IRF-4 and IRF-5 mRNA gene expression via qRT-PCR. MDA-MB-231 cells were exposed to CM and co-cultured cells to evaluate cell viability through MTT assay over 24, 48, and 72 hours, with qRT-PCR used to examine breast cancer-related gene expression. Results: The results indicate that co-culturing M0 macrophages with MSCs promotes M1-like macrophages, as evidenced by upregulated IRF-5 and suppressed M2 macrophage-related genes. Treatment with CM from M0/MSCs co-culture significantly inhibits MDA-MB-231 cell proliferation at 72 hours, accompanied by reduced TNF-α levels. Notably, CM treatment downregulates AKT1 and YKL-39 genes in MDA-MB-231 cells, suggesting potential anti-cancer effects. Direct co-culture with M0/MSCs, however, shows no significant impact on TNBC cell growth. Conclusion: This study highlights MSCs' ability to induce M0 macrophages to a M1-like phenotype and suggests that CM from M0/MSCs co-culture may contain anti-cancer factors targeting AKT1 and YKL-39 genes, underscoring the potential of MSC-mediated macrophage activation as a strategy to enhance BC treatment, especially in the context of TNB

Comparative analysis of segmented correlation trimmed mean algorithm for locating random and static partial discharges in power cables
No full textPower cable monitoring for partial discharge (PD) source is a crucial act to identify the cable’s insulation weakness before the cable breakdown. Recently segmented correlation trimmed mean (SCTM) algorithm had been applied to double-end PD measurement method. The algorithm showed significant improvement in performance when applied to PD source localization on power cables. However, the previous research study only focuses on the performance of the SCTM algorithm for static PD localization. This paper employs a random PD model to evaluate the accuracy of the SCTM algorithm in detecting PD sources. MATLAB simulations compared SCTM algorithm's performance for random PD generation and static PD sources in doubleend PD measurements. Results showed signal-to-noise (SNR) significantly influenced localization accuracy. Maximum PD estimation error ranged from 0.0539 to 0.0891 for random PD scenarios, while for static PD, it remained consistently at 0.0102 across all SNRs. The average PD estimation error was consistently lower for SCTM with static PD locations. As SNR improved, average errors converged to 0.0102 for both scenarios, indicating increased accuracy with lower noise levels. In conclusion, the SCTM algorithm is more effective when used with static PD locations for power cable monitoring, leading to more accurate PD estimations. This research enhances the reliability and efficiency of PD source localization, vital for preserving power cable integrity and preventing breakdowns
Causes of poor supervision in malay language teaching in primary schools
No full textThis study examines the teaching practices of Malay Language in primary schools within the Tenom district, focusing on teachers who did not achieve outstanding scores in their Teaching and Learning Practice supervision. The research aims to explore this phenomenon by analysing teaching practices and identifying the factors contributing to these unsatisfactory supervision scores. Consequently, the study proposes recommendations to improve Malay Language teaching practices, helping teachers enhance their teaching and learning implementation. The study is grounded in Danielson's 1996 Framework for Teaching, which includes key components such as planning, classroom environment, instructional approaches, and teachers' professional responsibilities. A qualitative research design with a phenomenological approach was employed. Participants comprised Malay Language teachers selected via purposive sampling based on their teaching supervision scores. Data collection involved interviews, observations, and document analysis, which were subsequently transcribed and analysed using content analysis techniques, aided by Atlas Ti version 22 software. The findings indicate that teachers often plan lessons inadequately, focusing primarily on teaching objectives without considering the diverse knowledge levels of their students. Additionally, they rarely utilize diverse digital teaching materials and infrequently adopt modern instructional approaches, such as 21st-century activities, differentiated learning, digital learning, and edutainment elements
