An effective method of facilitating student learning in a laboratory environment is “practice by doing”. The study of modules related to signal-processing for digital communications requires deep mathematical and theoretical foundations but the practice goal is not really emphasized in the undergraduate curriculum at the University of Mauritius. This causes the students to lose interest in the corresponding modules resulting in high rate of failures. In this work, we propose to develop laboratory experiments with a view to bridge the gap between theoretical and practical aspects in the field of Massive Multiple-Input Multiple-Output (MIMO) systems for 5G cellular networks. Various laboratory scenarios are set up that consider a Maximum Ratio Combining (MRC) receiver in the uplink with an uncorrelated Rayleigh fading channel. Moreover, from a signal processing perspective to enhance the student’s understanding, we analyze the efficiency and error performance of Massive MIMO systems with MPSK and MQAM modulation schemes as well as perfect and imperfect channel estimates. The leading industry software package MATLAB R2022 is used to develop all laboratory experiments and the codes are elaborated in this analysis. Data collected from the experiments are used to generate spectral efficiency and error performance curves which can be used for future research. The findings underscore the significance of accounting for both scenarios and illuminate promising avenues for future research in the realm of massive MIMO education and learning. The assimilation of MATLAB® flowcharts for each MRC receiver, MPSK, and MQAM with perfect and imperfect Channel State Information (CSI) adds further depth to the study, ensuring a comprehensive understanding of the intricacies of massive MIMO systems. Ultimately, this contribution helps in the nurturing of expertise such that future generations of wireless communication pioneers can be inspired.

Road projects require a lot of earthworks. Sometimes, the soil in place has an insufficient bearing capacity; hence, the need to look for soil with required specifications. When a material is too far from the construction site, its transportation costful and time spending to the project. In offshore sedimentary basins, materials mostly available are sandy clay soils. This paper focuses on the improvement of the bearing capacity of sandy clay soil for different road pavements. Two solutions were investigated: lithostabilisation of sandy clay soil with volcanic rocks and cement stabilisation at different percentage in various curing conditions. Physical, geotechnical and mechanical properties were assessed on samples. It was found that, at 25% mix with volcanic gravel, sandy clayed soils are useable for the T2-T3 subbase layer and at 35% the mix can be stabilised with cement for the T2-T3 base and T4-T5 subbase layers. 4% cement dosage is the optimum for the three pavement layers. This dosage can be reduced to 2% for the T2-T3 subbase, if the negative impacts from environmental waters are counteracted. With a close look on the respect of prescribed procedures, sandy clayed soils in offshore sedimentary basins are useable for the construction of pavement layers.

Authors:   Thuong Mai University, Vietnam, Ha Le Hai
Published: May 2024

In recent years, mixed-frequency data analysis models have received much attention and application in the fields of economics and finance, especially in forecasting national macroeconomic indicators. However, in Vietnam, there are almost no studies applying these models. Vietnam is a country with a long-standing agricultural production background and the workforce mainly makes a living from farming. There are many types of Vietnamese agricultural products with high export value, bringing a significant source of foreign currency to the country. Coffee is Vietnam's main export product, a product that earns a lot of foreign currency, contributing to the country's socio-economic development. Therefore, applying models with mixed frequency data such as MIDAS to forecast coffee export growth is a promising new research direction.

Authors:   Dai Nam University, Hanoi, Vietnam, Huong Tran Nho
Published: May 2024

This study explores the perceptions of dopamine-stimulating activities among students and the challenges faced by teachers in implementing these activities in language education at Dai Nam University. A mixed-methods approach was employed, involving surveys and semi-structured interviews with 220 non-English major students and language teachers. The surveys assessed students' perceptions of various dopamine-stimulating activities, including gamified vocabulary acquisition courses, interactive language games, reward-based speaking activities, physical activity breaks, and project-based learning with rewards. Results indicate varying perceptions across academic years, with first-year students expressing the highest perceptions of effectiveness, followed by a decreasing trend in perceptions among higher-year students. Teachers reported challenges such as balancing novelty with meeting specific learning objectives, resource constraints, and classroom management difficulties. Qualitative data from semi-structured interviews with language teachers provided additional insights into the challenges and strategies encountered in implementing dopamine-stimulating activities. Themes emerged around the excitement and perceived effectiveness of these activities, specific activities utilized by teachers (such as interactive games, multimedia presentations, and real-world simulations), challenges faced, positive outcomes observed (including enhanced student engagement, participation, and language proficiency), and the need for flexibility and creativity in overcoming challenges. The study highlights the importance of considering students' perceptions and challenges faced by teachers in optimizing the effectiveness of dopamine-stimulating activities in language education. Tailored approaches to address varying perceptions and challenges are necessary to ensure meaningful engagement and promote effective language learning experiences. The findings contribute to the ongoing discourse on innovative pedagogical approaches in language education and offer practical implications for educators seeking to enhance student engagement and learning outcomes.

Trafficking in persons is an intrinsic form of an act that violates human dignity and dignity. Therefore this form of act, in addition to violating the law, also violates the principles of human rights. It can be concluded that human rights are the inherent essence of human beings which are natural and fundamental as God's gift that must be respected, maintained and protected by every individual, society or state. The method used in the study is a normative juridical approach. The normative juridical approach is an approach carried out based on secondary data in which there are legal materials including primary, secondary and tertiary legal materials related to one another with research studies. The results of this study know the construction of law enforcement as a series of processes to apply legal values, ideas, and ideals. The provision of criminal sanctions by the Indonesian state is implemented into the Criminal Code (KUHP) and must also refer to specific criminal law, Number 21 of 2007 concerning the Eradication of Trafficking in Persons. Meanwhile, efforts to combat trafficking in persons can be carried out by preventive measures, repressive countermeasures and preemptive countermeasures.
Are Artificial Sweeteners A Public Health Hazard?
Authors: Bansal Rahul
Published: May 2024

It was a shocking news for all of us in India that a 10 year old Patiala girl Manvi died after consuming a cake on her birthday ordered from a local bakery through a food delivery app. Some media reports have blamed high level of saccharine in the cake.(1) According to another media report Health Minister of Punjab has ordered enquiry on her death.
Whatever may have been the reason for this unfortunate event one thing is for sure that there is going to be a review/debate about the safety of these artificial sweeteners which are routinely added to various fast foods to enhance their taste including many soft drinks. Some of the commonly used artificial sweeteners are – aspartame, saccharine, sucralose, neotame, acesulfame-K, and stevia.
Recently a news was published in Times of India - ‘Artificial Sweetener in sodas possibly carcinogenic: WHO’.(2) In this article it was written that – “World Health Organisation agency declared on Thursday that aspartame, an artificial sweetener widely used in diet drinks and low sugar foods could possibly cause cancer. The declaration by WHO agency of a cancer risk associated with aspartame reflects the first time the prominent international body has weighed in publicly on the effects of nearly ubiquitous artificial sweetener. Aspartame has been a contentious ingredient for decades.”

Published: May 2024

Background: Out-of-pocket expenses (OOPE) are the primary means of funding healthcare costs in developing nations, and when the cost is too high, it leads to catastrophic healthcare expenditures (CHE). Aim & Objective: This study aimed to assess the proportion of households that faced CHE and also examined the associated factors that determine CHE at the household level. Methods and Material: Between September 2020 and February 2021, a cross-sectional study covering a sample of 771 households was conducted in four districts of Assam. A multistage sampling design was employed to select the sample households. Statistical analysis used: Binary logistic regression analysis has been performed to ascertain the factors that could determine household CHE. Results: 23% households had experienced CHE, high dependence on the private healthcare system. Monthly household income, duration of illness, presence of children under five years of age and elderly members, education of household head, and health insurance were the significant factors influencing CHE. Conclusions: The study identified the growing use of private healthcare services as a major concern that contributes to the prevalence of CHE. To make all healthcare services accessible and affordable and to lower OOP on healthcare, it is also crucial to improve the infrastructure and quality of the public healthcare system in rural and remote locations.

Sulawesi Island has fairly high economic growth but is not followed by a significant decrease in income inequality. Therefore, a new strategy is needed to overcome these problems, one of them by increasing the role of the financial sector through financial inclusion. This study aims to analyze the relationship between financial inclusion, economic growth, and income inequality, as well as the factors influencing them in Sulawesi Island from 2011 to 2019. The analytical method used is the simultaneous equation model with panel data using the EC2SLS model. The results show that there is a simultaneous relationship between financial inclusion and economic growth and also between economic growth and income inequality. Economic growth has a positive and significant effect on financial inclusion. Financial inclusion, foreign direct investment, and government spending have a positive and significant effect, while income inequality has a negative and significant effect on economic growth. Financial inclusion and inflation have a positive and significant effect, while economic growth has a negative and significant effect on income inequality. Thus, this study can show that financial inclusion can reduce income inequality by promoting economic growth.

This paper investigates the relationship between economic growth and CO2 emissions from 1994 to 2018 using a panel approach from eight ASEAN countries. We found an established result using the Panel ARDL Pooled Mean Group method. First, the panel Cointegration analysis shows a significant long-term relationship between GDP and CO2 emissions. Second, the error correction mechanism shows a stable and consistent value. Third, we found that GDP has a significant long-term effect on CO2 emissions in ASEAN countries. Fourth, our results also show that GDP significantly impacts CO2 emissions in the short term for four countries: Indonesia, Malaysia, Thailand, and Cambodia. Based on these empirical results, implications and policy recommendations are presented. ASEAN countries should implement green growth policies by encouraging economic development which does not suppress the environment.

Published: May 2024

We developed an extension project at the Universidade Federal do Rio Grande do Norte (UFRN), and includes students, teachers, other servers and the external community. Our goal with this article is to present the reports of our project members and discuss about the contributions of the practice of aikido in relation with health as an existential phenomenon and with the care of the self. Methods: Questionnaires were applied to collect data about the following information: 1) if you are part of the internal community (server, student or professor) or external to the university; 2) age; 3) practice time; 4) your opinion about what health is; 5) the impact of aikido practice on the practitioner's health; 6) whether aikido can be understood as a health practice. and were analyzed by theme content. Results: 34 practitioners volunteered to fill out our questionnaire. From the external community, 14 members answered the questionnaire, and from the internal community, one is a teacher, two are employees, and seventeen are students. From the reports, we are allowed to perceive health as a dynamic phenomenon made up of social, cultural, biological, emotional, and spiritual aspects, among others. Conclusion: Aikido addresses many of these spheres and promotes selfknowledge and caring for oneself and others, reflecting about their experiences and their health through interpretative elaborations of their own condition. Such attitude strengthens the idea that there is a hermeneutic dimension of health that has elements that can be narrated and analyzed.

US National Park Service and concession staff perceptions regarding waste management in Yosemite, Grand Teton, and Denali National Parks
Authors: Taff B. Derrick , Lawhon Ben , Freeman Stephanie , Pitas Nick , Newman Peter
Published: May 2024

Each year, over 45,000 metric tons of waste are generated in US national parks through a variety of means, including park operations, visitation, and other sources. In an effort to address these impacts, the National Park Service (NPS) has partnered with commercial and non-profit organizations to implement the Zero Landfill Initiative (ZLI). The goal of the ZLI is to realize a steady decrease in waste generated in parks, and an increase in materials being sent for recycling. Through this initiative and aligning research, efforts to mitigate waste and recycling issues with visitors is underway; however, to date there have been no attempts to understand the perspectives of those individuals who manage these parks on a daily basis. This study explored Theory of Planned Behavior-based constructs regarding disposal of waste and recycling using surveys with NPS employees and park concession staff in Yosemite, Grand Teton, and Denali National Parks. Results indicate that perceived difficulty and moral norms related to disposal of waste and recycling are significant drivers of self-reported behavior and intent with NPS and concession staff. Generally, concession staff perceptions align with the goals of ZLI more than those of NPS staff. This research adds to the limited understanding of land mana­ger perceptions, and results provide justification for future messaging and trainings that could improve sustainable management of these and other NPS units in the future.

POST-FITTING PRACTICES AMONG TRANSFEMORAL AMPUTEES AT ARUA REGIONAL REFERRAL HOSPITAL. A PROPOSED STUDY.
Authors: Asianzu Sylvia Cynthia , Katende Joseph
Published: May 2024

Background
Prosthetic fitting aims to enable the patients to achieve maximum functional independence considering the patient’s pre-amputation lifestyle, their expectations, and limitations. Activities to maximize independence in everyday life include self-care like dressing, feeding, bathing, and toileting among others with or without prostheses. Post-fitting management refers to follow-up activities performed by the rehabilitation team after the amputee has been fitted and discharged with a prosthesis to ensure maximum functional independence amidst the gait training and the accurate static and dynamic alignments done by the orthopedic technologists, patients have continued to present with these problems. Post-fitting management is essential to achieve the functional independence of the amputee. And it needs to be a continuous process. A person with an amputation in the prosthetic phase can continue to improve greatly if he is taught about the major goals of the post-fitting stage Therefore, post-fitting management needs to be reinforced and made continuous to prevent such occurrences among transfemoral amputees. The study aims to assess fitting practices among transfemoral amputees at Arua Regional Referral Hospital.
 Discussion
There is a a need for continued studies about prosthetic fitting whose aim is to enable patients to achieve maximum functional independence considering the patient’s pre-amputation lifestyle, expectations, and limitations. Proper assessment of post-fitting practices among transfemoral amputees will shed more light on the progress of management amputees and establish the existing challenges and areas of concern that may need to be addressed by both the patients and health workers. The findings of the assessment may contribute to the overall prognosis of current and future post-fitting patients and offer a foundation for further research.

Đặt vấn đề: Tăng huyết áp là một bệnh lý mạn tính phổ biến, nổi bật trong chăm sóc sức khỏe cộng đồng, gây ra nhiều biến chứng, gánh nặng cho gia đình và xã hội. Việc tuân thủ trong điều trị dùng thuốc và tuân thủ thay đổi lối sống ở người bệnh tăng huyết áp sẽ góp phần giảm biến chứng và gánh nặng do bệnh gây nên. Mục tiêu nghiên cứu: Xác định tỷ lệ tuân thủ điều trị tăng huyết áp và một số yếu tố liên quan đến đến tuân thủ điều trị tăng huyết áp của người bệnh đang được quản lý điều trị tại xã Yên Sơn - huyện Lục Nam - tỉnh Bắc Giang. Phương pháp nghiên cứu: nghiên cứu mô tả cắt ngang có phân tích trên 290 đối tượng đang được quản lý điều trị bệnh tăng huyết áp. Kết quả: Tỷ lệ tuân thủ điều trị không dùng thuốc chiếm 68,6%, tuân thủ dùng thuốc theo Morisky chiếm 73,8% và tuân thủ chung chiếm 54,1%. Kết quả phân tích hồi quy logistic đa biến cho thấy có mối liên quan có ý nghĩa thống kê giữa nhóm tuổi dưới 60, nam giới và mối quan hệ không tốt với thầy thuốc với tuân thủ điều trị chung (p<0,05). Kết luận: Tỷ lệ tuân thủ điều trị chung ở bệnh nhân tăng huyết áp còn chưa cao. Tỷ lệ này bị ảnh hưởng bởi tuổi, giới tính và mối quan hệ bệnh nhân với thầy thuốc
