Abstract	In this study, porous biochar (PBC) was prepared by acid activation of biochar derived from food waste (FWBC) and used as a suitable approach for the removal of 4-chlorophenol (CP) in wastewater. The characterization of PBC and the influent of different experimental conditions are determined. After the acid activation process, the surface area, porosity, and functional groups of PBC were developed. The removal performances of CP (1 mg/L) by PBC and FWBC were archived at 97.8 and 82.1%, respectively. Adsorption kinetics and isotherms of CP were followed by the second-order and Langmuir models, respectively. The maximum capacities of CP uptake onto mono-layer of FWBC and PBC based on the Langmuir model were determined at 79.8 and 108.7 mg/g, respectively. Besides, PBC could remove more than 89% CP from wastewater within 45 min of reaction time and it is suitable to reuse 8 times with over 60% adsorption efficiency of CP. In addition, the adsorption mechanism and environmental impact were discussed in detail. This work could bring a sustainable approach to the treatment of CP in wastewater as well as the management of food waste in Vietnam.

Abstract	Aristotle believed that objects fell at a constant velocity. However, Galileo Galilei showed that when an object falls, gravity causes it to accelerate. Regardless, Aristotle's claim raises the possibility that people's visual perception of falling motion might be biased away from acceleration towards constant velocity. We tested this idea by requiring participants to judge whether a ball moving in a simulated naturalistic setting appeared to accelerate or decelerate as a function of its motion direction and the amount of acceleration/deceleration. We found that the point of subjective constant velocity (PSCV) differed between up and down but not between left and right motion directions. The PSCV difference between up and down indicated that more acceleration was needed for a downward-falling object to appear at constant velocity than for an upward "falling" object. We found no significant differences in sensitivity to acceleration for the different motion directions. Generalized linear mixed modeling determined that participants relied predominantly on acceleration when making these judgments. Our results support the idea that Aristotle's belief may in part be due to a bias that reduces the perceived magnitude of acceleration for falling objects, a bias not revealed in previous studies of the perception of visual motion.

Abstract	Although environmental pollution affects the earth's atmosphere and increases the seawater level, these issues get little attention from policymakers and scientists. This academic paper explores the multifaceted factors contributing to environmental pollution in the member states of the Association of Southeast Asian Nations (ASEAN). Environmental pollution is a growing concern globally, and ASEAN, a region undergoing rapid economic development, faces unique challenges in mitigating its impact. Therefore, there needs to be more research in analyzing the factors that affect environmental pollution. This paper aims to test the determinants affecting ecological pollution for the green and sustainable economy in the ASEAN countries. This paper used the data from Word Bank for the period 2000–2020 in 09 ASEAN countries such as Vietnam, Laos, Cambodia, Myanmar, Indonesia, Malaysia, Thailand, Brunei and Singapore. The paper uses the unrestricted fixed and random panel data method. The STATA software 17.0 is used in the research and processes the regression model. The article reviews existing literature, statistical data, and case studies to identify and analyze key factors influencing environmental pollution in ASEAN countries. The new contribution of this research is that ASEAN countries are paying more attention to importing green products to develop a green and sustainable economy. The study considers various dimensions: industrialization, urbanization, agricultural practices, policy effectiveness, and socioeconomic factors. By understanding these factors, policymakers and stakeholders can develop targeted strategies to address and mitigate the environmental pollution crisis in the ASEAN region.

Abstract	Purpose – This study aims to estimate the pass-through rate of the increases in the excise tax and TCF tax on tobacco in Vietnam. This study seeks to shed light on how the tax burden is split between consumers and producers and inform policy discussions in the country. Using panel micro-level data collected from three waves of a nationwide retailer's survey, this study provides an evidence-based pass-through estimation for tobacco tax in Vietnam and contributes to the understanding of tax policy on smoking and smoking-related issues. Design/methodology/approach – Following increases in the excise tax and TCF tax on tobacco in 2019, the differential effect of the tax hike on the “treatment group” (domestic cigarettes) versus the “control group” (illicit cigarettes) using a difference-in-difference (DID) analysis has been studied. The study utilized unique longitudinal retailers’ data on cigarettes prices in Vietnam from 2018 to 2019 to estimate the tax pass-through rate for some of the most popular factory-made cigarette brands. Findings – This study found evidence of an over-shifting of cigarette taxes on smokers. Specifically, it discovered that the tax increase is absorbed more by low-priced brand smokers compared to premium brand users due to (1) the limited increase in prices under a pure ad valorem system and (2) the way the Vietnamese currency is denominated. Additionally, there is evidence of cushioning to mitigate price shock on consumers as the real prices increase gradually over the period of one year after the tax change. Originality/value – To the best of the authors’ knowledge, this study is the first to collect and analyze a unique panel micro-level data from three waves of a nationwide retailers’ survey, which captures the changes in marketing and pricing strategies of the tobacco industry in Vietnam before and after an increase in excise tax in 2019. The results of this study could be used as a reference for future policymakers in considering increasing taxes on tobacco.

Abstract	Introduction: The purpose of this study was to evaluate the effectiveness of dual light-emitting diode (LED) blanket phototherapy compared with combination LED phototherapy on the rate of total serum bilirubin (TSB) decline and treatment duration among full-term neonates with hyperbilirubinemia. Methods: A retrospective chart review of 255 newborns with hyperbilirubinemia admitted to a free-standing, university-affiliated, nonprofit, tertiary care Children's Hospital was conducted. Phototherapy type, duration, and rate of TSB decline were compared. Results: The rate of TSB decline was significantly higher among neonates treated with combination LED phototherapy than neonates treated with dual-blanket phototherapy (p <.0001). There was no significant difference in phototherapy duration. Discussion: Combination phototherapy resulted in a more rapid decline in TSB but did not shorten phototherapy duration compared to dual-blanket phototherapy. Phototherapy duration may have been confounded by variability in the timing of TSB laboratory draws. Further comparative effectiveness studies are recommended.

Abstract	In many studies in Vietnam, the scientists only focus on economic growth and attracting foreign direct investment. Environmental pollution has not been paid much attention in Vietnam. Therefore, this paper aims to identify the factors affecting environmental pollution in Vietnam. The author gathered the annual information based on World Bank data from 2000 to 2022. Data were processed via STATA 16.0; linear regression was used in this research. The results show that renewable consumption, economic growth and foreign direct investment inflow positively affect environmental pollution in Vietnam. Renewable consumption, foreign direct investment and economic growth have a strong effect on Vietnam’s environmental pollution. The empirical results show that if renewable consumption increases 1% then CO 2 emission will increase 1.19%; if FDI inflows increase 1% then CO 2 emission will increase 1.39%; and if GDP increase 1% then CO 2 emission increase 1.26%. This research also gives some solutions with which Vietnam could develop a green and sustainable economy in the future.
