Environmental sciences ,GE1-350 - Abstract
A scientific and reasonable assessment of port competitiveness will facilitate a comprehensive understanding of the current development of Chinese container ports along the Maritime Silk Road. Considering the network attributes of ports and the repetitive information among indicators, this paper proposes a novel port competitiveness evaluation and grading model based on entropy-improved catastrophe progression method. On the basis of a directed and weighted shipping network, the “dominance” indicator is innovatively introduced. The evaluation system including land-oriented competitiveness, sea-oriented competitiveness, hinterland support capacity and production and operation capacity provides a comprehensive assessment of port competitiveness. It is found that: land-oriented and sea-oriented competitiveness have the greatest influence on port competitiveness. A pattern of “One core, two wings, and four ports’ coordination” has been developed among coastal ports in China. The competition among ports in the Bohai Rim region is fierce, and production and operation ability of ports in the southeast coast needs to be strengthened. Fuzhou port and Rizhao port have high hinterland support and high development potential. The results of this paper can provide decision support for the development and upgrading of China’s coastal ports under the Maritime Silk Road initiative.

The science of ecology is incorporated into farm development and operation through agroecological techniques. A paradigm shift in agriculture is essential to combat hunger, adapt to climate trade, and mitigate environmental degradation. By doing this, researchers may further acknowledge the interdependence of farmed and nonfarmed landscapes and the variety of products and services that robust ecosystems offer, including resilience, nutrient cycling, and pest control, all of which can help sustain yields. Agro-ecology relies heavily on the knowledge and experience of farmers since it fosters independence and decreases reliance on costly outside resources. The concepts of sustainable intensification and agroecology are examined in this paper as additional strategies to address the global issue of increasing food production while lowering environmental impacts. Also, this study evaluates how effectively these approaches boost crop yields, lower environmental costs, and build resilience to climate unpredictability by closely examining existing programs, integrated management strategies, and field experiments. Supporting the findings is a comparative table that shows several techniques of sustainable intensification and how they have an effect on yields and environmental costs. In order to expand resilient, sustainable, and equitable food systems, a discussion of the necessity of a paradigm shift towards agroecological strategies is addressed in the paper's conclusion.

System evaluation research on user experience applied in using mobile applications. Systematic review of papers taken from the last 6 years, papers published in conference publications or journals, and papers available in English. The strategy used in searching for 30 articles was to create research questions, search for keywords appropriate to the topic, carry out inclusion and exclusion and ensure the quality of the paper assessment. From various studies that evaluate application user experience, I found that there are many factors that have not been fully successful, so researchers use the questionnaire method more because they think this method is easier to reach users widely. This literature review aims to explore users’ experiences with system services, and why users who are experienced with mobile applications are likely to continue using those applications. This systematic review is a methodology for identifying, evaluating, and defining relevant research on this topic answering several research questions and using a replicable and verifiable process that aims to find out what has not met user expectations. The main findings of this literature review are the percentage results of factors that influence user experience, techniques used to evaluate user experience and the benefits of evaluating user experience.

Environmental sciences ,GE1-350 - Abstract
According to WHO (2022), tuberculosis (TB) is the primary cause of ill health and the leading cause of death globally. It is estimated that approximately a quarter of the world’s population has been infected. With 372,367 cases of tuberculosis in 2022, the Philippines is among the top eight countries that accounted for more than 66% of all TB cases worldwide. Region III, along with NCR and Region IV-A, is one of the regions in the Philippines with the highest incidence of TB. This paper utilized the geographical information system (GIS) for easier visualization, and Getis-Ord Analysis, a type of spatial analysis tool for quick interpretations to provide an evidence-based framework for TB response. The spatial analysis was conducted to (1) determine if there are clusters of TB cases in the region across various periods and (2) determine if there are hot spots of TB cases in the most recent TB data covering 2019, 2020, and 2021. The results indicate that only the 2019 TB cases exhibit significant non-random clusters. It is recommended that further investigation be conducted to determine if the spatial clustering in 2019 is associated directly or indirectly with the El Niño event that occurred that year. On the other hand, the non-significance of the results for the years 2020 and 2021 may be attributed to the underreporting due to the implemented health protocols implemented to minimize the spread of COVID-19 which affected the accuracy of the reported cases. The results of the paper may be used for optimal resource allocation in addressing the spread of the disease.

Environmental sciences ,GE1-350 - Abstract
Energy poverty is an issue, which is new to the scientific field and often omitted from the research. The contemporary approaches to it are various, still the major of them points that energy poverty exists in case the national energy sector and the economy in general lack the possibilities to provide sufficient, safe, reliable, and affordable energy to the consumers. This paper examines the energy sector of Pakistan to prove or refute the idea of energy poverty existence in the country. In addition to that the energy poverty in Pakistan, in case it exists needs to be defined, its reasons are to be examined and the possible solutions for its alleviation provided. The paper proves the mentioned idea with the help of the approach from the side of international infrastructure construction. The proposed approach includes the examination of the role of BRI in energy poverty alleviation in Pakistan. While the Initiative has a significant impact on the economy of the country, its energy sector isn’t directly affected by BRI. The major results of the study encompass the following: the energy poverty measurement through index method is developed, based on demand for energy and its supply and imports’ changes; the energy poverty in Pakistan persists and can’t be alleviated by the international institutions; the effects of economic growth aren’t automatically distributed in the economy, especially in the energy sector of the country and have limited effects on energy poverty.

Environmental sciences ,GE1-350 - Abstract
Large steel silos are typically thin-walled structures, widely used in agriculture and industry to store large quantities of bulk materials. In the presence of steel solids in cylindrical shells the stiffness of the contents has a positive influence on the Silo walls, similar to internal pressure. In order to clarify the influence of the interaction between steel silos and bulk materials, the paper establishes a model for the interaction between steel silos and bulk materials using finite element simulation based on the European steel silo specification, and applies the theoretical analysis of mathematical modelling. The results of the study showed that: Wheat storage material and steel silos interaction stiffness values range from 0.0025 to 0.01 N/mm3 and 0.003 to 0.015 N/mm3; the value of the lateral pressure on the wall of the silo will be reduced as the radial displacement of the wall of the silo wall increases with the movement outwards; and the wheat storage stiffness of this paper was verified by literature test results. Provides a reference for the stability of steel silos containing wheat storage material in realistic situations.

Climate change as a challenge imposes an obligation on nations to indicate that climate change mitigation is at the core of their domestic policymaking. As a responsible stakeholder in climate change mitigation, India responded by announcing constitutional protection for the environment under the constitution. Since then, India has enacted several legislations to protect and conserve the environment. In 1994, the Environmental Impact Assessment (EIA) was one such attempt to forecast and mitigate possible harm to the environment. Recently, the Government of India has amended the EIA process by introducing changes to the law through the EIA Notification 2020. The paper identifies the problems associated with recent changes and produces empirical evidence to substantiate the study. It further attempts to appraise the Sustainable Development Goals and the importance given to environmental impact assessment by international organizations including the World Bank and the Asian Development Bank. The paper further studies several best practices in the European Union and concludes by suggesting law reforms in Indian law.

Machine learning algorithms have quickly risen to the top of several fields' decision-making processes in recent years. However, it is simple for these algorithms to confirm already present prejudices in data, leading to biassed and unfair choices. In this work, we examine bias in machine learning in great detail and offer strategies for promoting fair and moral algorithm design. The paper then emphasises the value of fairnessaware machine learning algorithms, which aim to lessen bias by including fairness constraints into the training and evaluation procedures. Reweighting, adversarial training, and resampling are a few strategies that could be used to overcome prejudice. Machine learning systems that better serve society and respect ethical ideals can be developed by promoting justice, transparency, and inclusivity. This paper lays the groundwork for researchers, practitioners, and policymakers to forward the cause of ethical and fair machine learning through concerted effort.

These manuscripts present a closed-loop IGBT-based fourquadrant chopper drive system for DC motors. This paper intends to improve DC motor control’s accuracy, effectiveness, and adaptability in a variety of applications. In this paper, we build and put into practice a closed-loop control system that incorporates IGBT in order to manage the speed and torque of DC motors in both directions. A feedback system with sensors for measuring motor speed and current is used in the closed-loop control scheme to ensure perfect regulation of motor parameters. The IGBT-based chopper drive architecture allows for smooth switching between forward and reverse motor operation as well as dynamic braking, making it appropriate for applications requiring four-quadrant operation. The main benefits of our suggested system are greater motor protection through fault detection and quick responses to external disturbances, improved speed and torque management, and lower energy consumption. We show experimental data that demonstrate our design’s capacity to maintain stable motor functioning across a variety of operating situations, validating its usefulness in real-world applications. The presented system simulation result is verified in MATLAB/Simulink software. The demonstrated results are motor speed, torque, current and voltage.
