The purpose of this research is to explore the factors that determine the digital literacy of workers in Vietnam today. The exploratory factor analysis (EFA) used for survey information obtained from 699 employees working at many institutions and domestic enterprises showed five significant impact factors. Statistical meanings of digital capacity include: Basic and advanced digital capabilities in general and digital finance and banking in life; Learning about and with technology; Choosing the right technology; The processing and management of information on the digital economy, finance and banking; The communication and cooperation in digital economy, finance and banking; Legal and ethics of digital technology. The results of ANOVA analysis show that: there is a difference in digital competence between groups with IT majors at university level and other groups; There is a difference in digital capacity between the office level and other groups; However, no difference in digital competence was found between the group of directors and the group of employees. The policy recommendation is that Vietnam should have a policy to strengthen the digital capacity of Vietnamese workers in association with the national argument transfer program. In particular, strengthen training for management leaders (directors) to improve the acceptance of new technologies and support the digital transformation process in Vietnam.

Drilling mud is generated during exploratory drilling and oilfield development, and consists of a mixture of soil, rock contaminated with oil, chemicals, and drilling fluid. It is very difficult and expensive to treat this waste source, so the biosurfactant produced by microorganisms is considered a highly effective biological treatment method. Biosurfactant is a bipolar compound that allows the dissolution of insoluble substances in water, creates an emulsion that helps microorganisms better contact the oil and easily decompose the contaminated oil. This study was carried out to evaluate the ability to degrade oil in drilling mud using biosurfactant produced by some microbial strains. The results showed that four microbial strains selected from Cat Ba, Hue and Vung Tau areas, namely Brevibacteria celere, Oligella ureolytica, Stenotrophomonas maltophilia and Paenibacillus mancerans have the capacity of decomposing oil in drilling mud. The highest emulsification index (E24) of the four strains after 5 days culture with shaking at 200 rpm, pH = 7.5, temperature 30°C, 1% NaCl, carbon source of saraline and DO were recorded at 73, 71, 52 and 59%, respectively. This result shows that biosurfactants are an active compound group with potential in oil pollution treatment in the Petroleum industry in particular and environmental pollution treatment in general.

The rule of breaking rock has practical significance in the process of controlling the blasting for the optimization of mine production or construction of blasting works. The equations describing the particle size distribution after the explosion are established in an experimental form corresponding to the specific conditions of the blasting work. It only has the meaning of a mathematical regression function and does not reflect the characteristics of the rock type, explosive conditions and explosive results. This research has exploited the theory of rock breaking from the point of view of probabilistic energy to establish the equation of rock breaking of claystone in water. This is a form of semi-empirical equation, which contains 4 empirical coefficients reflecting rock characteristics, explosive conditions, explosive energy absorption characteristics of rocks and actual destruction volume, determined for each type of rock. Through conducting experiments, processing experimental data and solving a system of four equations, four coefficients of the equations that characterize the breaking properties of claystone under the seabed have been found. The error of the average particle size between the actual and calculated values from the equations is less than 7% to 10%. Tt is possible to confirm the accuracy of the semi-empirical equation describing the particle size distribution rule when the claystone is exploded underwater.

Rice husk ash and rice straw ash are common agricultural wastes in developing countries. Currently, utilizing these wastes in the construction sector such as soil improvement and cement concrete production is a trend in many areas around the world. In Vietnam, with a rice production of more than 40 million tons/year, millions of tons of rice husk ash and straw ash can be generated. This is an abundant and a cheap material source. This article will research and evaluate the potential of rice husk ash and straw ash for soft soil improvement in Vietnam. Research results show that straw ash and rice husk ash are materials having high pozzolan activity. Various studies in the world and some studies in Vietnam showed that rice husk ash and straw ash not only improve some physical and mechanical properties of soil but can also partially replace the amount of binder. Vietnam has different types of soft soil and construction activities are increasing, so the demand for improving soft soil is also increasing. In which, improving soil with cement binder is one of the most popular methods. Therefore, rice husk ash and rice straw ash have great potential to combine with cement in improving soft soil in Vietnam. Utilizing these wastes not only helps reduce the negative impact their causes on the environment but also helps improve construction quality and reduce construction costs.

The growing population in major cities around the world requires significant development of transportation infrastructure, especially underground system. It requires the construction of more subway lines, and larger tunnel cross-sections. In underground construction, a cross-sectional shape which is a combination of circular and rectangular tunnels is an advanced trend. This shape incorporates the advantages of both forms. There are two terminologies used to classify these shapes, including sub-rectangular and quasi-rectangular tunnels. While the sub-rectangular tunnel lacks an interior column, the quasi-rectangular tunnel includes an interior column located at the center of tunnel. Recent studies focus on separately investigating the behavior of sub-rectangular and quasi-rectangular tunnels using various methods such as numerical methods, analytical methods, and experimental methods. The present study conducted a numerical comparison of these two types of tunnels. The results indicated that the presence of an interior column help to increase the stability of the lining structure. The internal forces within the quasi-rectangular tunnel with an interior column are smaller than those of the sub-rectangular tunnel and quasi-rectangular tunnel without an interior column.

The IPCC's 6th Assessment Report in 2023 highlights Vietnam's undeniable vulnerability to climate change, ranking it among the most severely impacted countries. In response, experts developed the CMIP6-VN dataset, offering high-resolution downscaled temperature and precipitation data tailored for Vietnam using the CMIP6 GCMs model. This study aims to analyze climate projections for Vietnam throughout the 21st century, incorporating data from 25 models to provide valuable insights into potential future climate scenarios. The investigation compares projected temperature and precipitation changes for the mid-term (2040÷2059) and long-term (2080÷2099) periods relative to the historical period (1980÷2014) in the six sub-climatic regions of the country. The results show a consistent upward trend in average temperature, projecting an average of 2.30C (SSP2-4.5) and 4.30C (SSP5-8.5) increases by the end of the century. The Northern regions, especially the Northwest, are experiencing the most significant temperature rise, while moving towards lower latitudes, the temperature increase becomes less severe. The Southern regions, on the other hand, are experiencing a relatively lowest temperature increase. Rainfall variability indicates a slight increase across Vietnam by the century’s end, aligned with rising temperatures, though not as pronounced as the temperature changes. This study emphasizes temperature disparities between the Northern and Southern regions, with the Northwest showing the highest increase and the Southern region displaying the least prominent rise. Policymakers and stakeholders can use these research insights to devise effective adaptation and mitigation strategies in addressing climate change challenges in Vietnam. Continued monitoring and further research are essential to enhance the accuracy and reliability of climate projections in the region, enabling Vietnam to better prepare and respond to the inevitable impacts of climate change.

Published: May 2024

Filtration is a long-standing process but the technology has changed slowly, mainly based on the increase in filtration pressure and changes in the characteristics of filter media. The problem is high moisture remains product, requiring more expensive technologies (thermal drying) and long processing times. In the mineral processing industry, not only concentrates but also tailings need to be dewatered. The test samples were Cam Duong apatite concentrated and tailing ore, Ta Phoi copper concentrated and Sin Quyen tailing ore, Cua Ong fine coal, and Dak Nong red mud. All samples’ properties have been defined by sieving analyses, SEM method, and gravitational density measurement. Then, samples were experimented with using the Nutsche high-pressure filtration in the variable operational parameters. While the sludge concentration affected the specific resistance, the filter cake height and filtration pressure did not affect as much. At the suitable condition (homogeneous filter cake, 1 bar pressure difference, and 50 grams solid weight), the specific resistance and residual moisture content of the filter cake are around 2.5x10-12÷1.5x10-13 m-2, 15÷25%, respectively. Through the test results, some recommendations are mentioned in order to perfect the process and scale up for industrial production.

Abstract: One of the most significant processes currently underway in the modern economic system is the digital transformation, which results in the digitization of all economic sectors and creates the digital economy. This represents the current stage of economic development that affected all areas of human life and changed the way the economy functions and the way people live. The production processes, organizational relationships, distribution networks, marketing strategies, customer communication forms, and the way in which customers get goods and services have all undergone substantial change as a result of digital transformation. Consequently, the economic system is shifting from traditional markets to interconnected networks, from traditional consumers to active prosumer, from ownership-based models to access-based models, and from a consumer-driven economy to a sustainable economy (Rifkin, 2015).
It should be mentioned that unlike traditional industries, which lack access to digital technologies, digital business and entrepreneurship can raise the rate of economic growth and create jobs in a short period of time. The digital economy has risen 2.5 times faster than the global GDP over the last 16 years (Huawei and Oxford Economics, 2017). Today, we are living in the process of the digital revolution, or the fourth industrial revolution, which has put a strong demand on individual countries to start digital transformation. This is critically important for small countries that are not rich in natural resources.
As a result, it's critical to evaluate the current stage of digital business growth, trends in the emergence of digital business models and entrepreneurial initiatives, as well as the difficulties associated with the digitization of traditional industries.
The study highlights the benefits of digital entrepreneurship and business over traditional ones.  The stages of traditional businesses' digital transition are discussed, along with the models of digital business and entrepreneurship that are currently in use.

Abstract. Financial markets have become a center of attention and a field of study for over a century, especially nowadays when there is an abundance of data about them, however, behavior of financial markets still stays as mystery and a field that is rife with unpredictability and uncertainty. There are many methods and techniques for analyzing time series data. Due to the fact that prices are formed by decisions made by millions of people across the planet the price in itself holds the reflection of all of those decisions which itself is a natural process. Therefore, we can look at the financial data as a fractal object and analyze them. Method that has been primarily used to analyze time series is fractal dimension which we can use to measure of the time series, in other words, we can measure how correlated is the time series and thus have an opinion about its future behavior. As we later find out, fractal dimension provides interesting insights into the time series and most importantly, it is a method that can analyze pictures and thus it is not restricted by data formats.

Abstract: Consumer brand preference (CBP) is a precursor to a consumer’s final purchase decision of a product, and is an important area in the field of consumer buying behaviour. This is particularly so owing to the multitudinous array of competing products in the market place. Thus, the purpose of this study is to investigate the variables that influence consumers' brand preferences for powdered milk in the study area. In order to realise the objectives of the study, data were drawn from a sample of 381 milk consumers in Delta and Edo States in Southern Nigeria, using stratified and purposive sampling methods. The data generated were analysed with descriptive and inferential statistics including frequency tables, cross tabulation, ANOVA and multiple regression. The results of the cross-tabulation of monthly income and milk brands reveal that ‘Dano’is the most preferred (17.3%) powdered milk brand, while ‘Milksi’ is the least preferred (5.8%) by consumers across all income groups. The multiple regression results indicate that CBP for milk powder is significantly influenced by consumers’ attitude, reference groups, product quality, consumption emotions, television advertisement and product price, with positive consumption emotions as the dominant predictor. The study also found significant variation in CBP with respect to educational status, household size and income. Therefore, milk producing companies should adopt pragmatic pricing and marketing strategies to reach desired target segments in order to sustain customers’ patronage and ensure they remain loyal to their brands.

Abstract: This research explores how the global COVID-19 pandemic has created unprecedented obstacles for the tourist business, which have led to rapid changes in its landscape. Specifically, it looks at how tourism organizations have adopted technology and changed their marketing methods. The study examines the complex links between technology adoption, organizational dynamics, and external environmental factors using the Technology-Organization-Environment (TOE) paradigm as a conceptual lens. The research posits and empirically tests four hypotheses: (1) the pandemic significantly influences a shift from classical to digital marketing strategies, (2) organizational dynamics play a crucial role in the successful integration of digitization efforts, (3) external environmental factors, particularly the pandemic, shape the urgency and nature of digitization strategies, and (4) effective analysis of various indicators, feedback mechanisms, and sales metrics significantly contributes to the success of digital marketing strategies. In order to obtain valuable insights, the study uses statistical techniques such as logistic regression, multiple regression analysis, correlation evaluation, Chi-Square tests, and logistic regression that were carefully designed and distributed to eighteen tourism companies affiliated with Georgia's national tourism agency. Results highlight the paradigm shift towards digital marketing brought about by the pandemic, the critical role played by organizational dynamics, the impact of external environmental factors, and the critical importance of data-driven analysis in augmenting the effectiveness of digital marketing in the tourism industry. In order to help stakeholders in the tourism industry navigate the possibilities and difficulties provided by the post-pandemic digitally altered landscape, this research adds a nuanced understanding of the complex dynamics surrounding technology adoption, digital strategies, and organizational responses.

Authors: Prasad Bhatt Ramesh
Published: May 2024

During the exploration, loss of global forest and biodiversity, climate changes and emissions were evaluated and determined the best ways to restore the world's ecosystem using green energy. The suggested primary land use data were collected and collated forest resources were assessed. Ways of biodiversity conservation strategies and status were evaluated. The GHG emission was inventoried and calculated. Author inferred that primary forest loss in the tropics increased by 10% in 2022, with the Amazon destroyed in 2020. The world's forest cover is decreasing, with significant losses in sub-Saharan Africa and Latin America. The world's total 3 3 growing stock of trees fell slightly from 560 billion m in 1990 to 557 billion m in 2020, with 606 Gt of living biomass and 59 Gt of dead wood. However, biomass per unit area has increased. During the period of incidence of COVID, reduced emissions by 5.2% was noticed. With a mean temperature of 1.11°C, 2021 was one of the seven warmest years on record. The main source of worldwide total GHG emissions from exclusive land use are CO , CH , and N , which account for 2 4 2 72%, 19%, and 6% of emissions respectively while F gases from other sources contribute only 3%. The forest ecosystems absorb 2 billion tons of CO per year, and emissions can be reduced through 2 natural synergies between climate preservation and development, such as increased energy demand and renewable energy

Authors: Dwivedi Sneha , Singh Balwant , Kumar Singh Alok , Kumar Singh Vinay
Published: May 2024

The cultivation of Pleurotus is gaining momentum due to its nutritional value and economic potential. The preparation of mushroom spawn on grain media involves inoculating them with pure cultures of certain mushroom species under sterile conditions, yet contamination of the spawn is a significant barrier to the growth and spread of mushroom farming in underdeveloped nations. In this study, the spawn growth of Pleurotus species on various grain substrates including maize, wheat, sorghum and bajra was explored. The results revealed significant differences in spawn growth duration among the substrates. Maize substrate exhibited the longest duration for spawn growth, requiring 19 days, while wheat, sorghum and bajra substrates displayed shorter duration of 15, 10 and 11 days respectively. Furthermore, each substrate demonstrated distinct characteristics influencing spawn growth, highlighting the importance of substrate selection in Pleurotus species cultivation. These finding provide valuable insights for optimizing spawn production process and enhancing the efficiency of Pleurotus species cultivation practices.
Hiding in plane sight: the unrecognised impact of aviation on the Maltese landscape
Authors: Burgess Anthony
Published: May 2024

In many ways, the impact aviation has had upon Malta is obvious; one only has to see how its airport dominates Malta’s landscape, the importance of tourism to its economy (an industry almost wholly reliant upon civil aviation) or even walk into its capital to be confronted by the bombed remains of the Royal Opera House to evidence this. In this paper, in addition to briefly outlining some of the ways aviation has directly impacted upon the archaeology of Malta, its other more subtle, hidden and unacknowledged impacts will also be examined. In doing so, new information and insights are revealed to uncover the true depth of Malta’s aviation archaeological heritage, and how it continues to influence and shape Malta to this day.

The dynamic response of the grid to any change in its transmission power is always fluctuating. In the past, only thermal power plants were used to supply the power required by the demand, but nowadays renewable energy resources have taken a significant share. Due to the inherent intermittent of this type of renewable energies, the dynamic responses of the network have also become more intense, and therefore it is necessary to use special equipment and control strategy to improve stability and maintain normal condition in generating the required power, especially in the fault conditions. In this project, a microgrid including a wind power plant with a capacity of 2 MW is used, which is connected to the main grid. To maintain the stability of the microgrid, a device called STATCOM is used, which can maintain the voltage level of the network at the desired value by injecting reactive power. In order to evaluate the efficiency of the proposed system, four different operating conditions including normal status, single phase to ground fault, two phase to ground fault and three phase to ground fault are modeled and the obtained results show that the use of STATCOM can play a major role in improving the stability level of the network.

Urban rail transit systems consume significant electrical power, with traction accounting for 50% of the total energy (from China Urban Rail Transit Association [1]). As operational mileage and vehicle counts rise, so does energy consumption, underscoring the importance of vehicular energy conservation. This study evaluates the impact of on-board energy storage devices on train energy efficiency. Using operational data from Changsha Metro Line 5 and incorporating literature reviews and simulations, the energy-saving potential was assessed. Integrating these storage devices with vehicle energy monitoring systems shows promising potential for energy conservation and operational efficiency. This research presents a viable strategy to reduce energy consumption in urban rail vehicles, enhancing system competitiveness.

The future of BIM is exciting and full of challenges, but there are several obstacles to implementing BIM effectively in the construction sector in Indonesia. Thus, the aim of this research is to examine the challenges of implementing BIM on construction projects, especially in Indonesia. Data was obtained from 45 respondents who answered questionnaire questions, including owners, consultants, contractors/subcontractors, private companies and state-owned enterprises representing construction parties in Indonesia. Empirical analysis using the Correlation Coefficient-A Measure of Linier method states that there are seven variables which are challenging variables in implementing BIM in construction projects. The seven challenge variables are BIM technical readiness, organizational paradigm changes regarding BIM, work environment awareness of BIM, compliance on BIM rules, increased competency and skills, consistent application of effective leadership, maturity of BIM utilization. These seven challenge variables have a linear relationship with the application of BIM in Indonesian construction projects. In conclusion, construction project parties in Indonesia must responses positively to these seven challenges to ensure that the implementation of BIM in construction projects in Indonesia is in accordance with the regulations released by the government.

With the provisions of the Fourth Dictum of the UUPA, regarding the position of the Surakarta Kasunanan Palace as a cultural heritage area, there are still differences of opinion regarding its ownership status. This research aims to examine the position of the Surakarta Kasunanan Palace after the enactment of the UUPA, as well as to analyze the ownership status of the Surakarta Kasunanan Palace as a cultural heritage area. The research method is normative juridical. The type of data used is secondary data. Data analysis techniques using deductive reasoning presented descriptively. The results of this research are: first, the position of the Surakarta Kasunanan Palace after Indonesian Independence, based on: Law Number 10 of 1950 was designated as part of Central Java Province; and based on Law Number 18 of 1965, de jure Swaraja Surakarta was abolished. Then, after the UUPA came into force, the position of the Surakarta Kasunanan Palace should have shifted to the State. However, in reality, currently the Surakarta Palace Sultanate still has and exercises authority over the lands it owns and owns based on Presidential Decree Number 23 of 1988. Second, the ownership status of the Surakarta Kasunanan Palace as a cultural heritage area is stipulated in the Regulation of the Minister of Culture and Tourism Number PM.03/PW.007/MKP/2010 belongs to the Surakarta Kasunanan Palace as an indigenous community in accordance with Article 13 of the Cultural Heritage Law. The Surakarta Kasunanan Palace is a traditional community, because the King is the traditional leader who still has the same territorial area and lineage and has authority within and outside his traditional area. If the Kasunanan Surakarta Palace is interpreted as a traditional institution, and ownership of the land of the Surakarta Kasunanan Palace becomes a customary right for the Surakarta Kasunanan Palace, then as a consequence the Government in taking over the land of the former Surakarta self-government must also pay attention to the principle of recognizing these customary rights.

This paper presents a novel approach to harness energy from human footsteps using piezoelectric sensors. With a focus on addressing the energy needs of densely populated regions such as China and India, where foot traffic is abundant, this work endeavours to convert mechanical energy from footsteps into electrical energy.  A prototype hardware model has been designed and presented to generate power through human foot movement, employing piezoelectric sensors arranged in series and connected via a rectifier diode to charge a battery. Additionally, a voltage booster is integrated to amplify voltage output, while an inverter facilitates the conversion of DC to AC power. Experimental investigations were conducted by varying the weights of individuals to establish a correlation between weight and resulting voltage outputs, culminating in a graphical representation of the data. The outcomes of our study showcase the feasibility of tapping into untapped energy reservoirs from foot traffic, thereby presenting promising applications for urban settings. This work contributes towards addressing energy challenges prevalent in densely populated areas and underscores the potential of piezoelectric energy harvesting technology as a sustainable energy solution.
