Introduction: Metacognition is essential in the teaching-learning process, as students who are aware of their own thinking processes tend to be more effective in acquiring knowledge and skills.Objective: To determine if there is a relationship between metacognition and motivation in Peruvian basic education students.Methods: Quantitative research, non-experimental design with correlational scope. The sample consisted of 130 students who responded to two questionnaires characterized by adequate metric properties.Results: Preliminarily, it was found that students applied metacognitive processes efficiently and their level of motivation was high. On the other hand, it was determined that the Kendall's Tau b correlation coefficient for both variables was equal to 0.501 and the p-value was lower than the significance level (p<0.05). This implies that those students who were more aware and reflective about how they approached their academic activities, how they planned and executed learning strategies, tended to be more motivated in their studies.Conclusions: It was determined that there is a direct and significant relationship between metacognition and motivation in Peruvian basic education students. Therefore, it is suggested that teachers promote activities that develop self-reflection and awareness of thinking processes. This may include self-assessment exercises and learning journals

Introduction: Pro-environmental behavior constitutes an essential topic within contemporary environmental research. In a global context where awareness of environmental challenges is constantly growing, understanding how students relate to their environment and adopt practices that promote sustainability becomes imperative. Objective: To assess the pro-environmental behavior of fifth-grade secondary education students. Methods: A quantitative, non-experimental, and cross-sectional descriptive study was conducted. The sample consisted of 164 students of both sexes who were administered the Environmental Behavior Questionnaire, an instrument with adequate metric properties. Descriptive statistics were used for analysis, and the non-parametric Chi-Square test was employed to determine if pro-environmental behavior was significantly associated with proposed sociodemographic variables. Results: It was found that the pro-environmental behavior of 28% of students was occasional, 23.7% was uncommon, 19.5% was habitual, 18.8% was not habitual, and 10% was very habitual. When evaluating dimensions, it was also found that recycling and reusing, resource conservation, and environmental purchasing were predominantly valued at the occasional level. Likewise, a significant association was determined between pro-environmental behavior and students' sex (p<0.05). Conclusions: The pro-environmental behavior of fifth-grade secondary education students was assessed as occasional. Therefore, it is recommended that educational authorities develop educational programs and awareness campaigns to promote the adoption of pro-environmental behaviors

Digitally designed – Qatar Faculty of Islamic Studies
Authors: Lewis Ben
Published: April 2024

This paper describes the digital parametric design and fabrication optimisation that was carried out on the recently-completed Qatar Faculty of Islamic Studies building in Doha, Qatar. The processes, tools and techniques used are described, with background given about the issues and decisions that led to their development and implementation. The benefits we believe these tools brought to the project are also discussed, from the point of view of both the building’s construction and Arup's internal workflow. The paper focuses on the building's roof structure, which is completely free-form, architecturally defined by a 3D doubly-curved NURBS surface. The roof’s surface area is approximately 13 500m2 and is constructed from curved plate girders, each one unique. The roof's geometry ranges from areas with a radius of curvature of approximately 500m, therefore relatively flat, to areas of high curvature with a radius of 5m or less.

What is your structural model not telling you?
Authors: Kannan Ramaseshan , Hendry Stephen , Kaethner Chris
Published: April 2024

Finite-element analysis involves inherent approximations and numerical errors. In addition to these, the increasing size of structural models and the use of automated workflows for creating them can lead to hidden user errors in these models. In order for an engineer to have confidence in the analysis results, it is necessary to be aware of how these errors manifest themselves in models, what impact they have on analysis results and, most importantly, how they can be detected. We present novel numerical techniques that the analyst can use to 'debug' their models and verify the accuracy of their analysis results. These techniques have been implemented in software and have been successfully used by practising engineers working on real life projects.

Published: April 2024

This study set out to ascertain how work environment and stress affected productivity, with job satisfaction acting as a mediating factor. The purpose of this study was to improve the work productivity and job happiness of the nurses at Hasna Medika Hospital in Cirebon City. With the use of SmartPLS 3.0 software, this study employs quantitative data analysis techniques utilizing Structural Equation Modeling (SEM) based on Partial Least Square (PLS). At the Hasna Medika Hospital in Cirebon, 78 nurses were given questionnaires to complete in order to gather primary data. The findings demonstrated that job satisfaction was positively and significantly impacted by work stress. Furthermore, there was no discernible impact of the work environment or job stress variables on work productivity. Nonetheless, there is a sizable relationship between productivity and job satisfaction. The work environment and stress management are not the only factors that affect productivity and job happiness. Investigating additional factors that can help achieve this objective is crucial. These variables should be further investigated by researchers.

Published: April 2024

Objectives: To determine serum leptin levels and its correlation with pre-pregnancy BMI, BMI, and insulin resistance at 24 - 28 weeks of gestation and before delivery in subjects with gestational diabetes mellitus (GDM). Methods: A cross-sectional descriptive, longitudinal follow-up study with a control group on 115 pregnant women with GDM and 115 pregnant women with normal glucose tolerance (NGT) enrolled at 24 - 28 weeks of gestation and completed the study. The subjects' serum leptin levels were measured using the enzyme-linked immunosorbent assay (ELISA) method at 24 - 28 weeks of pregnancy and before delivery. The clinical characteristics, serum insulin levels, and homeostatic model assessment of insulin resistance (HOMA-IR) were also performed at both study time points. Results: Serum leptin levels in subjects with GDM were significantly higher than those in normal pregnant women at 24 - 28 weeks of gestation and before delivery (p < 0.001). At both study time points, there was a positive correlation between serum leptin levels and pre-pregnancy BMI, maternal weight, serum insulin levels, and HOMA-IR index in subjects with GDM (p < 0.05). Multivariable logistic regression showed that pre-pregnancy BMI and serum insulin levels were associated with hyperleptinemia       (p < 0.05). Conclusion: Serum leptin levels were higher in GDM and had a positive correlation with pre-pregnancy BMI, BMI, and insulin resistance at the time of the study. Pre-pregnancy BMI and serum insulin levels were independent factors related to increased serum leptin levels.

Authors: Nguyen Xuan Phuong , Nguyen Thanh Bac
Published: April 2024

Neurinoma is the most common benign nerve sheath tumor originating from Schwann cells. Most benign neurinomas are single. Patients with multiple tumors can be seen in conditions such as neurofibromatosis (NF) type 2, whose typical sign is bilateral vestibular schwannomas. Some authors have described it as a form of schwannoma, which presents multiple schwannomas without associating with NF factors. Studies have recognized this condition as the third major form of NF [1, 2, 3]. We describe a case of multiple schwannomas in the spine associated with schwannomas by imaging and surgical features to clarify the characteristics of this disease.

Published: April 2024

Blockchain technology is a revolutionary concept that has transformed various industries, offering decentralized and secure solutions for data management. At its core, a blockchain is a distributed and immutable ledger that records transactions across a network of computers. One of the key features of blockchain is its transparency, as each participant in the network has access to the same information. The application of blockchain technology extends across diverse sectors, with finance being the most promising and well-known application domain. Cryptocurrencies, like Bitcoin and Ethereum, rely on blockchain to facilitate secure and transparent transactions. The decentralized nature of blockchain eliminates the need for intermediaries, reducing transaction costs and increasing efficiency. Beyond finance, blockchain is making significant strides in supply chain management. The emergence of blockchain technology has paved the way for a transformative innovation in the realm of digital transactions: smart contracts. These self-executing contracts encoded in blockchain have garnered significant attention for their potential to revolutionize the way agreements are made, executed, and enforced. This paper explores the concept of smart contracts, delving into the underlying technology, finding applications across various industries, legal implications, and future prospects.
Exponential stabilization of the class of the switched systems with mixed time varying delays in state and control
Authors: Hoang Hoai-Nam , Duong Thi-Hong
Published: April 2024

This paper presents the problem of exponential stabilization of switched systems with mixed time-varying delays in state and control. Based on the partitioning of the stability state regions into convex cones, a constructive geometric design for switching laws is put forward. By using an improved Lyapunov–Krasovskii functional in combination with matrix knowledge, we design a state feedback controller that guarantees the closed-loop system to be exponentially stable. The obtained conditions are given in terms of linear matrix inequalities (LMIs), which can be effectively decoded in polynomial time by various computational tools such as the LMI tool in MATLAB software. A numerical example is proposed to illustrate the effectiveness of the obtained results.

Published: April 2024

Mukbang is an interesting form of entertainment. It has been attracting millions of viewers around the world. With wide coverage, Mukbang videos have a strong influence on viewers. Unlike previous studies, which only focused on the motivations to watch Mukbang videos or considered the negative consequences of excessive use, the present study is conducted to explore the positive impact of watching Mukbang videos on viewers’ mental health and eating habits. After conducting a literature review, we propose the relationship among variables based on the source attractiveness model, the compensatory Internet model, and the uses and gratification theory. The research uses both qualitative and quantitative methods. Research data was collected based on survey questionnaires from 192 Gen Z in Vietnam. The findings show that there are two factors that positively affect “Decision to watch Mukbang” in ascending order: “Entertainment” and “Indirect satisfaction”. Furthermore, the study results also indicate that the factor “Decision to watch Mukbang” has a positive relationship with both “Eating habits” and “Mental health”. Proposing solutions based on research results has contributed to helping Mukbang viewers explore the positives of this type of entertainment. Simultaneously, it helps a Broadcast Jockey know what factors viewers are interested in, thereby creating attractive videos.
Comparative analysis of the impacts of CPTPP and EVFTA on Vietnam’s textile export activities
Authors: Thanh Tran Thi Mai , Ba Duy Vu , Minh Ngoc Luong , Thanh Thao Nguyen , Thi Thu Duong
Published: April 2024

This paper presents a comprehensive comparative analysis of the impacts of two significant Free Trade Agreements (FTAs) – the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) and the European Union-Vietnam Free Trade Agreement (EVFTA) – on Vietnam’s textile industry. Utilizing a quantitative research methodology, the study systematically examines trade data to assess the relative effects of these agreements. The findings reveal that the CPTPP exerts a more substantial influence on Vietnam's textile exports compared to the EVFTA. This is primarily attributed to the CPTPP's more comprehensive market access and more advantageous tariff reduction schedules, which have significantly enhanced Vietnam’s export potential in key markets like Canada, Japan, and Mexico. On the other hand, the EVFTA, while contributing to a steady increase in exports to European markets, demonstrates a less varied impact. The paper’s unique contribution lies in its in-depth analysis of the differential impacts of these FTAs, providing critical insights into their role in shaping Vietnam’s position in the global textile market. The results of this study are particularly valuable for policymakers and trade strategists in developing and fine-tuning trade policies, highlighting the nuanced effects of different trade agreements on export dynamics in an increasingly interconnected global economy.
Drivers of sustainable entrepreneurship education: An analytic hierarchy process
Authors: Thi Thanh Hang Pham , Thi Hue Truong
Published: April 2024

This research aims to explore the drivers of sustainable entrepreneurship (SE) education for university lecturers and their hierarchy of prioritization. An Analytic Hierarchy Process (AHP) method was applied to analyze data collected from nine entrepreneurship-education experts based in eight universities in Vietnam. The results show that there are several identified key drivers, ranked based on descending prioritization, namely: encouraging youth, social problems, talent shortage, and connection with practitioners. Several sub-factors may also be ranked as having relative importance to SE, with the top five being “encourage students to engage in social enterprises”, “venture creation is our responsibility”, “students age group drives the educators’ interest”, “students engage in heated discussions”, and “failure of the established institutions”. This could be the first endeavor to assess and rank the drivers of SE education, thereby offering some meaningful contributions to both academia and practice.
Global bank linkages and foreign direct investment
Authors: Manh Ha Tran , Ngoc Thang Doan
Published: April 2024

This study explores the impact of bank networks on foreign direct investment (FDI) using data on country pairs. Global bank linkages are quantified by the number of connected bank pairs engaged in international lending between the source and host countries. The empirical analysis reveals a positive correlation between bank linkages and bilateral FDI stocks. We interpret this relationship as indicating that bank connections facilitate FDI by addressing information asymmetry stemming from factors such as uncertainty, global financial crises, or host country shocks. Our findings remain robust across various robustness checks. This research suggests that governments should promote cross-border bank investments to attract FDI.
The relationship between work environment and employees’ innovative work behaviours: A proposed model
Authors: Thi Thu Hai Tran , Thanh Lan Mai , Thi Minh Ngoc Luu
Published: April 2024

Employees’ innovative work behaviours (IWB) emphasize the multifaceted nature of employee contributions to organizational innovation, encompassing both the ideation stage and the necessary implementation behaviours that translate innovative ideas into tangible performance improvements. Fostering a work environment that encourages and celebrates IWB becomes crucial for organizations seeking to maximize their innovation potential. This study delves into the intricate relationship between work environment, encompassing both its social and physical facets, and IWB. Building upon theoretical foundations in innovation, innovative behaviour, and work environment research, the article presents an analytical framework to unravel the influence of these factors. The proposed framework leverages an integrated approach by combining insights from Affective Events Theory (AET) and Expanded Person-Environment Fit (PEF) theory. This integrated lens posits that IWB are shaped by both the social and physical environment, mediated by innovation trust, with personal innovativeness acting as a moderator. This framework paves the way for further research in the fields of innovation management.

Published: April 2024

Objective: The objective of the current study was to find out the independent and interactive effects of prilled fat supplementation with protein on the production performance of early lactating Nili Ravi buffaloes.Methods: Sixteen early lactating buffaloes (36.75±5.79 d in milk; mean±standard error) received 4 treatments in 4×4 Latin-square design according to 2×2 factorial arrangements. The dietary treatments were: i) low protein low fat, ii) low protein high fat, iii) high protein low fat, and iv) high protein high fat. The dietary treatments contained 2 protein (8.7% and 11.7% crude protein) and fat levels (2.6% and 4.6% ether extract) on a dry matter basis.Results: The yields of milk and fat increased with increasing protein and fat independently (p≤0.05). Energy-, protein-, and fat-corrected milk yields also increased with increasing protein and fat independently (p≤0.05). Increasing dietary protein increased the protein yield by 3.75% and lactose yield by 3.15% and increasing dietary fat supplies increased the fat contents by 3.93% (p≤0.05). Milk yield and fat-corrected milk to dry matter intake ratios were increased at high protein and high fat levels (p≤0.05). Milk nitrogen efficiency was unaffected by dietary fat (p>0.10), whereas it decreased with increasing protein supplies (p≤0.05). Plasma urea nitrogen and cholesterol were increased by increasing protein and fat levels, respectively (p≤0.05). The values of predicted methane production reduced with increasing dietary protein and fat.Conclusion: It is concluded that prilled fat and protein supplies increased milk and fat yield along with increased ratios of milk yield and fat-corrected milk yields to dry matter intake. However, no interaction was observed between prilled fat and protein supplementation for production parameters, body weight, body condition score and blood metabolites. Predicted methane production decreased with increasing protein and fat levels.

Objective: The objective of this study was to determine internal structure spectral profile of by-products from coffee processing that were affected by added-microorganism fermentation duration in relation to truly absorbed feed nutrient supply in ruminant system.Methods: The by-products from coffee processing were fermented using commercial fermentation product, consisting of various microorganisms: for 0 (control), 7, 14, 21, and 28 days. In this study, carbohydrate-related spectral profiles of coffee by-products were correlated with their chemical and nutritional properties (chemical composition, total digestible nutrient, bioenergy values, carbohydrate sub-fractions and predicted degradation and digestion parameters as well as milk value of feed). The vibrational spectra of coffee by-products samples after fermentation for 0 (control), 7, 14, 21, and 28 days were determined using a JASCO FT/IR-4200 spectroscopy coupled with accessory of attenuated total reflectance (ATR). The molecular spectral analyses with univariate approach were conducted with the OMNIC 7.3 software.Results: Molecular spectral analysis parameters in fermented and non-fermented byproducts from coffee processing included structural carbohydrate, cellulosic compounds, non-structural carbohydrates, lignin compound, CH-bending, structural carbohydrate peak1, structural carbohydrate peak2, structural carbohydrate peak3, hemicellulosic compound, non-structural carbohydrate peak1, non-structural carbohydrate peak2, nonstructural carbohydrate peak3. The study results show that added-microorganism fermentation induced chemical and nutritional changes of coffee by-products including carbohydrate chemical composition profiles, bioenergy value, feed milk value, carbohydrate subfractions, estimated degradable and undegradable fractions in the rumen, and intestinal digested nutrient supply in ruminant system.Conclusion: In conclusion, carbohydrate nutrition value changes by added-microorganism fermentation duration were in an agreement with the change of their spectral profile in the coffee by-products. The studies show that the vibrational ATR-FT/IR spectroscopic technique could be applied as a rapid analytical tool to evaluate fermented by-products and connect with truly digestible carbohydrate supply in ruminant system.

Philosophie des Leidens
Authors: Wandruszka Boris
Published: April 2024

‘No human being lives without suffering, suffering is everywhere,’ says Euripides. And yet no one could say what suffering is exactly and what happens when we suffer. Therefore, it is worthwhile to pursue the ‘inner life’ of suffering and uncover its basic structure or basic dynamics, its being, its essence, its sense or nonsense and its value or lack of value. In doing so, we can show that suffering conceals much more than one would expect, for it contains the whole human being, his/her world position, his/her fundamental fate of existence and thus the ‘meaning of the world’. And finally: Whoever understands suffering, really understands it deeply down to its last reasons and has the chance to deal with it in the right way, i.e. in a way that promotes life.

„Wo alle Herzen heldenmüthig schlugen“
Authors: Minelli Kelly
Published: April 2024

This historiographical study deals with the transformation of heroic images of German and French soldiers and officers during the Seven Years' War and the Revolutionary and Napoleonic Wars. A culture of sensitivity, levée en masse and intensive forms of opinion management on the part of governments and military leaders led to a change in heroic-military role models, which was reflected in personal military testimonies. Following an interdisciplinary approach, the monograph uses narratives and self-portrayals to examine the heroization processes of military personnel and shows how combatants influenced and helped shape the culture of remembrance through their self-heroization.
Local Governments in Türkiye and Azerbaijan in the Context of the European Charter of Local Self-Government: Contradictions and Incompatibilities
Authors: Çolak Çağrı , Yıkıcı Abdulgazi
Published: April 2024

The Council of Europe (CoE) has attached great importance to local governments and local self-government in constructing an integrated Europe and, as a sign of this, has created an international convention entitled “the European Charter of Local Self-Government (ECLSG)”. The core aim of this investigation is to evaluate the local government legislation of Türkiye and Azerbaijan, which are contracting parties, within the framework of the principles and standards of the ECLSG. The assessment found that some of the articles/sub-articles on which both countries had made reservations have disappeared in practice, while some approved articles/sub-articles have yet not been incorporated into domestic legislation. Ultimately, Türkiye accepted twenty sub-articles (the minimum number required to accept the Charter) and made reservations for ten sub-articles. However, Türkiye is not applying the three articles it accepted and is actually applying nine of the ten articles for which it made reservations. On the other hand, Azerbaijan accepted twenty-six sub-articles and made reservations to four sub-articles. Like Türkiye, Azerbaijan does not apply the four articles it accepted, but actually applies three of the four articles to which it made reservations.

Wetland ecosystems play the most important role but are also vulnerable under economic evelopment activities in estuarine and coastal areas. The quality of the soil environment is an important parameter to assess human impacts on this ecosystem environment. In this study, 28 soil and sediment samples of different types of land use were collected and analyzed with physical indicators (mechanized action, pH, salinity), nutrient indicators (N total, P total, OC, Ca2+, Mg2+) to assess the current state of the soil environment in Dong Rui commune. The results showed a large difference in land indicator groups between 2 groups of land use types distributed inside and outside the levee. For the quality of soil environment in the group of types outside dikes such as river sediments and mangrove soils, the pH value is at a less acidic level, the composition is mainly sand, organic content, high exchange cations. For the group of land use types located inside the dike, the pH value is at the acidity level, the grain level composition is more balanced, the organic content and the ability to exchange cations is low. This difference shows the extent of human impact on these wetlands as well as their natural resilience, particularly in restored forest areas in abandoned shrimp lagoons. This is an important solution in the management and restoration of wetlands in Dong Rui commune.

Polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF) are the most toxic substances among the group of unintentional persistent organic pollutants (U - POP) generated from many sources, in which domestic and industrial waste incinerators are the highest emission risk. Assessment of pollution potential and dioxin/furan emissions from incinerators in developing countries, including Vietnam, is still limited; especially in-depth studies on the content and characteristics of PCDD/PCDF emitted into the atmosphere. Therefore, the research team evaluated the emission potential and characteristics of 07 PCDD and 10 PCDF, those are considered to be the most toxic isomers and congeners, from stack gas samples collected from incinerators at 33 facilities in 11 provinces in Vietnam. The total concentration of PCDD/PCDF in the industrial incinerators’ emission ranged from 37.3 to 3348.6 pg TEQs/m3 and domestic waste incinerators had lower total concentrations and fluctuated within about 37.3-1323.8 pg TEQs/m3. The characteristic of incinerator emissions is that the proportion of 2,3,7,8- TCDD accounts for 2.9 to 9.04%. The highest contributing concentrations were congeners 1,2,3,7,8-PeCDD, with its contributing percentage from 22.95-32.42%. The second largest contributor is congeners 2,3,4,7,8- PeCDF, accounting for 20.94- 21.50% of the total toxic congeners of PCDD/PCDF in both types of incinerators. However, in terms of toxic equivalency (TEQ), the concentration of industrial waste incinerators is much higher than that of domestic waste incinerators. The results of stack gas samples showed that the PCDD/PCDF content for domestic waste incinerators has 5/17 establishments that exceeded the permissible standard threshold: 0.6 ng/Nm3, according to QCVN 61-MT:2016/BTNMT. Industrial waste incinerators have 5/16 establishments that exceeded the permissible standard threshold: 0.6ng/Nm3 for furnaces with a capacity of 300kg/hour according to QCVN 30:2012/BTNMT.

Nickel-manganese-cobalt (NMC) transition metal oxide-based layered structural materials are evaluated a promising material for applications as cathode in lithium-ion batteries. In this study, we have successfully synthesized nickel-rich NMC material LiNi0.9Mn0.05Co0.05O2 by solid-state reaction method (NMC9.5.5- PR). The CR2032-type lithium-ion battery is also successfully fabricated from NMC material to serve the study of electrochemical properties. The NMC9.5.5-PR material exhibits outstanding discharge specific capacity when providing a maximum specific capacity of up to 212.4 mAh/g at a current density of 10 mA/g. However, the cycle efficiency survey results show that the NMC9.5.5-PR material has some disadvantages (only maintaining 81.6% of the discharge specific capacity after 50 continuous charge-discharge cycles at current density of 10 mA/g). These electrochemical properties indicate that it is necessary to further improve the cyclic efficiency of NMC9.5.5-PR material but preserving its outstanding electrical energy storage capacity. Successfully accomplishing this goal, we believe that NMC-9.5.5-PR or a material based on NMC9.5.5-PR will be one of the suitable materials to fabricate positive electrodes used in lithium-ion batteries.

On this research, the development of a simple, cost-efective and highly sensitive spectrophotometric method for acetamiprid detection based on the localized surface plasmon resonance of polydiallyldimethylammonium chloridestabilized gold nanoparticles. By naked eyes, one can detect acetamiprid by the visual change of gold solution color from red to purple, corresponding to the shift of maximum absorbance wavelength in the UV-Vis spectrum. Quantification of acetamiprid is possible through a linear relationship between the maximum absorbance wavelength and the acetamiprid concentrations in the range of 8×10-8 -2×10-6 M. Under the optimum conditions including pH 5, NaCl concentration of 0.02 M and incubation time 20 min, the present method has high precision (RSD < 5%), very low limit of detection (LOD) of 2.7×10-8 M, limit of quantification (LOQ) of 8.2×10-8 M. This method has been successfully applied to determine acetamiprid in several pesticide samples and vegetable samples. The measurement results of acetamiprid in the pesticide samples of the research method with the HPLC-UV method showed a difference of < 2%, while for the vegetable sample, the difference between the research method and the LC-MS/method method/ MS < 5% shows that the method has high accuracy and reliability.

This study was conducted in 2020-2021 to investigate several epidemiological factors and parents' knowledge of antibiotic use in children in Thai Nguyen and Ha Giang. Methods: 459 eligible subjects were investigated for epidemiological information and knowledge of antibiotic use. 275 bacterial culture were successfully done from nasopharyl swabs of participants. Results: Some epidemiological factors such as parents' smoking, a high percentage of pipe tobacco smoking (21.6%), and up to 30.7% of relatives living in the same house (including Ha Giang at 31.4% and Thai Nguyen at 30.0%). In children, medical history of tonsillitis accounted for 37.3%, with otitis media accounting for 11.5%. The average influenza incidence was 1.7 times per year in Ha Giang and 1.9 times per year in Thai Nguyen. The proportion of children with antibiotic consumption over the past year was 47.3% in Thai Nguyen and 34.7% in Ha Giang. Commonly used antibiotics were amoxicillin and cephalexin, and most parents did not remember or knew the names of the antibiotics their children were taking. There were 42.0% of parents who knew about the use of antibiotics that the effects of antibiotics could treat bacteria. This rate was 46.9% in Ha Giang and 36.8% in Thai Nguyen, both statistical significance with p< 0.05. Of those 275 bacterial culture from nasopharyl swab, 78 (28.4%) was detected S. pneumoniae, which concordance with previous literature review. Recommendations: Conduct communication and education programs to better understand the use of antibiotics and reduce risk factors for respiratory infections. Further investigation, intervention may needed to reduce risk in S. pneumoniae carriers.
