Education of Ho Chi Minh’s Moral Example for Students in Vietnam Nowadays

Ho Chi Minh was one of the thinkers and revolutionary activists who had special interest in morality. In anywhere or at any time, Ho Chi Minh always first spoke and wrote about morality. More importantly, Ho Chi Minh always acted and behaved in accordance with moral standards that he set. Ho Chi Minh not only left a moral ideological system but also an example of the moral standards that he raised. Ho Chi Minh's thought and moral example were not only of great value to revolutionary work of national liberation but in the current period of national development, becoming a solid spiritual foundation of life in Vietnamese society. Vietnamese students are educated youth, a source of high quality labor of society, is generation that continues the legacy of ancestor's revolution. In order to do that, to promote the strength of Vietnamese youth in the work of building and defending the country requires the family, school and society to take care of them and educate them and the formation of revolutionary moral characteristics for students is determined to be fundamental. Ho Chi Minh was the pure embodiment, the most typical of the pure and beautiful moral qualities; therefore, education of Ho Chi Minh's moral example becomes a matter of necessity. In this article, the author focuses on clarifying basic issues, namely: the concept of students and the education of Ho Chi Minh's moral example for students; Ho Chi Minh's moral example and contents of Ho Chi Minh's moral example needed to educate Vietnamese students nowadays.

Ho Chi Minh's Human Love

Ho Chi Minh was a Cultural, Great leader of the Vietnam revolution, a hero of Vietnam national liberation. Ho Chi Minh was a person who special interested in morality throughout the life of revolutionary activities. Moreover, Ho Chi Minh was also a person who thoroughly practices his moral sentiments. In which, covering all was the great love of Ho Chi Minh to the people of all circles, all sectors, all classes, which built from childhood and intact until Ho Chi Minh vented his last breath. That noble sentiment inspired Ho Chi Minh to embark on a revolutionary career with the sacrifice of hardship to get the mastery, a freedom, and happiness for the people. That sentiment was expressed naturally in Ho Chi Minh, from worries for big things like liberating people, building human development strategies to simple things associated with every human being with accomplishments specific scene. In this article, the author clarifies the love of people of Ho Chi Minh expressed through the years of revolutionary activities and by the sacred will of Ho Chi Minh left before going into eternity.

Teachers’ feelings of safeness in school-family-community partnerships: Motivations for sustainable development in moral education

This study aims to get insights into teachers' safety feelings in families, schools, and communities’ partnerships to facilitate the Vietnam context’s moral education process. We used a survey method with the instrument having 19 Likert-scale items, namely teachers' feelings of safeness in SFC partnerships (SSFC). The data from 371 Vietnamese teachers followed a simple random sampling strategy. We conduct multiple regression analyses to get insight into the relationship between four groups of variables and teachers' feelings of safeness, namely teachers’ background, collaborated actions between teachers and families, families’ mental encouragement for teachers, and collaborated actions between families and communities. These results find that the school level, collaborated actions between teachers and families, and families’ mental encouragement for teachers are statistically significant to teachers’ feelings of safety. Moreover, the variable group of collaborated actions between teachers and families records the highest positive beta value in multiple regression analyses. In other words, the improvement of collaborated actions between teachers and families is a critical motivation to leverage teachers’ feelings of safeness in SFC partnerships. These results provide valuable information for sustainable development in moral education

Effects of yeast extract and methyl jasmonate on the enhancement of solasodine biosynthesis in cell cultures of Solanum hainanense Hance

In this work, the effects of the elicitors methyl jasmonate (MeJA) and yeast extract (YE) on the growth and solasodine production of Solanum hainanense cells were investigated. The results showed that various concentrations of MeJA (50-250 µM) and YE (1-4 g/L) have different eliciting influences. The increase of solasodine content induced by the elicitation of 3 g/L of YE and 50 µM of MeJA at the beginning of cell culture was about 1.9- and 1.3-fold, respectively, as compared with that of the non-elicitated cells. In general, YE (biotic elicitor) was more effective in enhancing solasodine production than MeJA (abiotic elicitor)

REALIZATION OF BROADBAND AND INDEPENDENT POLARIZATION METAMATERIAL PERFECT ABSORBER BASED ON THE THIRD-ORDER RESONANCE

In this report, we studied numerically and experimentally the electromagnetic properties of perfect MAs using ring-shaped structures at microwave frequencies. By creating a magnetic resonance, the ring structure confines electromagnetic energy at the first- and third-order resonances. And then, we leveraged the super-cell structures, which consist of different rings in one unit cell to obtain broadband absorption. The results showed that the absorption band of MA is broaden from 1.3 to 2.17 GHz when the number of rings in the unit cell increases from four to nine-ring

The application of electro coagulation process for decolorization of reactive dyeing wastewater

In this study, the application of bipolar electro coagulation (EC) using iron electrode has been assessed for the removal of Remazol Black B in the simulated dye wastewater. The influence of different parameters involving pH, initial dye concentration, sodium sulfate concentration, electrolysis time, and electric current was investigated. According to the results, the anode dissolution rate can be significantly affected by the electric current and it can be found that at high sulfate concentration, the decolorization process cannot be improved. The best color removal efficiency was obtained was 98.8 ± 0.9% at pH of 10, dye concentration of 30 mg/L, and electrical current of 6 A during electrolysis time of 8 minutes. This result indicates that EC can be used as an efficient and “green” method for color removal from reactive dye solution

All-dielectric Metamaterial for Electromagnetically-induced Transparency in Optical Region

Metamaterial (MM) is emerging as a promising approach to manipulate electromagnetic waves, spanning from radio frequency to the optical region. In this paper, we employ an effect called electromagnetically-induced transparency (EIT) in all-dielectric MM structures to create a narrow transparent window in opaque broadband of the optical region (580-670 nm). Using dielectric materials instead of metals can mitigate the large non-radiative ohmic loss on the metal surface. The unit-cell of MM consists of Silicon (Si) bars on Silicon dioxide (SiO$_{2}$) substrate, in which two bars are directed horizontally and one bar is directed vertically. By changing the relative position and dimension of the Si bars, the EIT effect could be achieved. The optical properties of the proposed MM are investigated numerically using the finite difference method with commercial software Computer Simulation Technology (CST). Then, characteristic parameters of MM exhibiting EIT effect (EIT-MM), including Q-factor, group delay, are calculated to evaluate the applicability of EIT-MM to sensing and light confinement

Isolation an agar degradation Bacillus sp. AT6 and preliminary application for seaweed saccharification

Background: Agar is a common polysaccharide found in nature. However, agar is strongly resisted to the degradation processing, leading to limitation of its application in various areas. Thus, finding an effective solution for agar saccharification significantly improves the economically effects of agar based substrates.Methods: Soil samples were collected from TienPhong Forestry Ltd. Company, ThuyXuan District, ThuaThien Hue province, Vietnam. Potential agar degrading bacteria were screened on a mineral salt agar medium. The isolate was identified based on 16S rRNA nucleotide sequence, morphological, physiological, and biochemical characteristics. Agarase production was evaluated by modification culture conditions including incubation time, shaking speed, and initial inoculum size. Molecular mass of extracellular agarase was determined by native SDS-PAGE. The effect of pH, temperature, metal ions, and organic solvents were conducted for enzyme characterization. Application of enzyme was investigated on seaweed saccharification.Result: An agar degrading bacterial strain was isolated from soils and identified as Bacillus sp. AT6. Maximal agarase accumulation obtained in the culture containing an inoculum size of 10% (v/v), shaking speed of 210 rpm, and 96 hours incubation. The agarase revealed a single band on zymogram analysis with an apparent molecular weight of 180 kDa. The optimal temperature and pH were 40°C and pH 8.0, respectively. All tested metal ions and organic solvents partially decreased enzyme activity. Treatment seaweed by agarase resulted in reducing sugars release present in the reaction, indicating the saccharification of seaweed was succeeded.Conclusion: Bacillus sp. AT6 is a new report of agarolytic bacteria that produces extracellular agarase enzymes. The present results promise strain AT6 is a great candidate for agar saccharification for industrial application

RESEARCH AND PRODUCTION OF PERMEABLE CONCRETE AS A SUSTAINABLE SURFACE LAYER FOR URBAN INFRASTRUCTURES AND THE EFFECT OF MAINTENANCE METHOD ON ITS INFILTRATION CAPACITY

Recently, permeable concrete has been considered one of the "Best Management Practices" in rainwater collection and cleaning. The outstanding properties of this type of concrete are its relatively high porosity (typically 15 ÷ 30% in volume) and the linking/connection of the internal pore system resulting in high water permeability and retention. However, one of the limitations to the widespread application of this eco-friendly material is the decrease of permeable capacity over time due to the clogging materials and the lack of regular maintenance. This paper performs an experimental approach for manufacturing permeable concrete that has both high water permeability and meets the strength requirement (1). At the same time, the influence of clogging sand and typical maintenance methods on the infiltration rate of permeable or pervious concrete is presented (2). Based on the literature review and obtained experimental results in this study, maintenance measures to ensure the required permeability for urban surface structures and sustainable surface water drainage are also proposed (3)
