Opis:
M-learning is usually thought of as based on videos, digital materials, and high technology. Nonetheless, it is not a complete perspective of this new educational trend. Mobile devices with many functions can be an effective tool to support learning. Furthermore, learners nowadays, who were born in the 4.0 movement, are more familiar with mobile devices than notebooks. They spend much time on their mobile phones interacting on social media and playing mobile games. Hence, if educators can integrate those interests into traditional lesson plans, added value would appear for learners’ academic performance and learner autonomy. This paper proposes the idea of combining m-learning, gamification, and other factors influencing learning motivation into a mobile application to reinforce students’ learner autonomy. With a case study at Nguyen Tat Thanh University, we take a closer look at the effectiveness of the application on students’ language acquisition and a detailed description of how to best use the application along with lessons at schools. Using experimental methods with surveys and tests, this paper draws a bonding connection between students’ personal interest in the subject and their performance. The study provides thoughtful insights into utilizing m-learning and gamification to improve students’ learner autonomy and modernize language learning classrooms in this technological context.

Opis:
Działania na rzecz włączenia finansowego mają na celu zapewnienie wszystkim podmiotom funkcjonującym w gospodarce dostępu do odpowiednich usług finansowych i możliwości ich efektywnego wykorzystania. Zwiększenie włączenia finansowego stało się poważnym problemem zarówno dla krajów rozwiniętych, jak i rozwijających się. Istnieje wiele wskaźników włączenia finansowego, z których najbardziej podstawowym jest posiadanie konta w instytucji finansowej. Niniejszy artykuł ma na celu ocenę wpływu wskaźników włączenia finansowego na rozwój gospodarczy. Wyniki badań pokazują, że istnieją korelacje między dużą liczbą oddziałów banków, bankomatów, kredytu krajowego w sektorze prywatnym a wzrostem tempa rozwoju gospodarki. Rozwój ten umożliwi wzrost poziomu życia ludności. W artykule przedstawiono także zalecenia dla rządów krajów rozwijających się służące zwiększeniu włączenia finansowego.
Financial inclusion efforts seek to ensure that all members of an economy can have access to and effectively use appropriate financial services. Improving financial inclusion has become a significant concern for developed and developing countries alike. There are many indicators of financial inclusion, the most elementary of which includes having an account in a financial institution. This paper will evaluate the impact of indicators of financial inclusion on economic development. The result shows that correlations exist between large numbers of bank branches, ATMs, domestic credit in the private sector and the increased rate of development in the economy. People will gain a more prosperous life due to this development. The paper also provides recommendations for the governments of developing countries to improve financial inclusion.

Opis:
In this research, the weld track geometry in wire-arc DED (directed energy deposition) of ER308L stainless steel was predicted and optimized. The studied geometrical attributes of weld tracks include weld track width (WTW), weld track height (WTH), and contact angle (α). The experiment was designed based on Taguchi method with three variables (current I, voltage U, and weld velocity v) and four levels for each variable. The ANOVA was adopted to evaluate the accuracy of the models and impact levels of variables on the responses. The TOPSIS method was utilized to predict the optimal variables. The results indicated that the predicted models were built with high accuracy levels (R2 = 98.92%, 98.77%, and 98.91% for WTW, WTH, and α, respectively). Among the studied variables, U features the highest effects on WTW and α with 78.56% and 69.90% of contribution, respectively, while v is the variable that has the most impact on WTH with 39.82% of contribution. The optimal variables predicted by TOPSIS were U = 23 V, I = 140 A, and v = 300 mm/min, which allows building components with stable and regular geometry.

Opis:
This study investigated the effects of various maltodextrin contents (0, 6, 7.5, 9, and 10.5 g/100 g of pulp) on the drying rate and powder quality of avocado pulp dried by refractance window technique. Increasing the maltodextrin addition level significantly decreased the drying rate and prolonged the drying time. The maltodextrin considerably affected the drying rate of pulp when its moisture content was higher than 1.0 g/g dry weight. A significant improvement was found in the retention of total contents of phenolics and chlorophylls, antioxidant capacity, and color in avocado powder obtained from pulp with maltodextrin. The addition of 9 g maltodextrin/100 g of pulp allowed to retain 85.60% TPC, 78.78% total chlorophyll content, 83.48% DPPH radical scavenging activity, and 78.89% ferric reducing antioxidant power. However, maltodextrin in the amount of 10.5 g/100 g of pulp had a negative impact on moisture removal and deteriorated the quality of the dried avocado. These findings may have practical application for the production of dried avocado and other fruits.

Opis:
Mango powder is a nutrient-dense substance that can be used directly or as a supplement in food items. However, due to the high sugar content, the removal of moisture from mango was difficult. This study investigated an infrared drying technique for removing moisture from mango pulp to produce powder products. The experiment was designed in a three-factor full factorial design with the following variables: drying temperature (70, 75, and 80°C), maltodextrin content (0, 6, and 9 g/100 g pulp), and total soluble solid content (11 and 16°Brix). The findings indicated that the Weibull model was the most appropriate for describing the moisture removal of mango pulp during infrared drying. Higher temperature and maltodextrin content, along with reduced total soluble solid content, resulted in improved quality of the mango powder. Furthermore, the optimal drying conditions for mango powder were found as 11°Brix, 80°C, and 9% maltodextrin content, which could ensure the highest retention of total phenolics (59.874%), retention of reducing sugars (71.044%), total acidity (10.141%), and retention of DPPH radical scavenging activity (65.051%). To fully benefit from the rewards of infrared drying, it is essential to establish suitable pretreatment conditions or use additives to preserve component quality.

Opis:
Refractance window drying is an innovative technology belonging to the fourth generation of drying technologies that could enhance the quality of the dried product and improve the drying process. In this study, two factors with the type of fruit pulps (avocado and mango) and drying temperature (ranging from 80 to 95°C) were investigated. Results showed that in refractance window drying, the evaporation process rapidly occurred, mainly in the falling-rate period with undetectable constant-rate period. The Weibull was the best fit model among eight investigated mathematical models that could determine the drying behavior. The effective diffusivity was found to be from 4.2510-10 m2/s to 7.2410-10 m2/s for avocado pulp, and from 4.5010-10 m2/s to 10.6710-10 m2/s for mango pulp when the drying temperature was changed from 80 to 95°C. Moreover, the corresponding activation energy was 32.06 and 66.03 kJ/mol for avocado and mango pulp moisture evaporation, respectively, and the highest quality of powders of both dried pulps was obtained after processing at 90°C. The refractance window drying revealed a high potential in the production of fruit powders from avocado and mango due to the high retention of more than 80% of total phenolic content (TPC) and antioxidant activity. TPC could be used as a useful criterion for the evaluation of the drying process in terms of dried product quality.

Opis:
Nowadays, self-climbing formworks are commonly used in the construction of concrete buildings with a great height, such as high-rise buildings, silos, and bridge piers. A regular formwork can be improved to have more functions, e.g., the formwork itself can climb to the desired construction site. Climbing characteristics of the formwork as well as opening and closing characteristics of the formwork shell are essential criteria for evaluating the performance of a self-climbing formwork. The effective ones were mentioned in different studies, where most of them were published in patents of countries, e.g., the United States and China. Dissimilar from these studies, this paper presents several improvements for some certain groups to enhance the features of a hydraulic self-climbing formwork. Based on the analysis of the composition and the working principle of the actual climbing formwork types, a new opening and closing method of the formwork shells and a new rail clamping device are suggested. They are applied to design a self-climbing formwork with the shell’s working size of 4 m × 3 m. Their load capacity, as well as the flatness of the concrete surface after casting, are assessed. The proposed solutions can result in various advantages, e.g., the shorter initial alignment time, the increase of the quality concrete surface, and the maximal automation for construction operations.
