TRADITIONAL THERAPY AND WESTERN MEDICINE FOR TREATING INSOMNIA

Objective: The herbs that have been used in Vietnam since ancient times for many different uses but not everyone recognize its great value. The paperaims to discover the preferred medicinal plants and the reasons why patients choose them. Although Western medicines play an important role intreatment and bring immediate effect, however, to treat insomnia in the long term, natural herbs account for significant importance. The paper wasconducted in early 2019 in different regions in South Vietnam to once again determine the role of medicinal plants use.Methods: This paper is completed with the support of 100 respondents who are from some places of Ho Chi Minh city and are suffering from insomnia.With the form of direct interviews, some questions are designed to examine patients’ opinions about the strategies that can to treat insomnia.Results: The results showed that herbal treatment still plays a rather important role even though people tend to choose Western medications in busydays because this medications are less time consuming. The paper also mentions that the importance of herbs in the treatment of insomnia needsmore attention.Conclusion: In the current medical methods, traditional methods are being trusted and used by many people because this therapy brings many healthbenefits, helps patients treat their illnesses well as well as improve their health much better. Traditional remedies which are all derived from naturalherbs are very good for health

The Importance of Experiential Activities for Students: A case of Ho Chi Minh City, Vietnam

Experiential learning is a process that begins with practice, experimentation, and then the learner analyzes and reflects on the experience and the results of that experience. This process helps students consolidate knowledge, form and develop new competencies, skills, behaviors, and even new ways of thinking. This approach is considered to have many advantages compared to the traditional educational method. This research is completed based on analysis and assessment from survey activities and understanding the study habits of students, and the teaching methods of elementary, middle and high school teachers in Ho Chi Minh City. Through research, some schools in the city are still teaching and learning by traditional methods, the experiential activities alternating with classroom lessons are still rather new. Most of the students feel quite boring and monotonous when every day when they come to class, they listen to lectures, copy lessons, return lessons without any experiential activities. The inclusion of practical activities in the above lessons is very necessary to change the atmosphere in the classroom as well as help students to absorb knowledge in an intuitive and vivid way. And this research shows the benefits of practical experiences for learning and teaching in schools today. Methods of face-to-face interviews and questionnaires were used and then analyzed using a fivepoint Likert scale. The research results confirm the role of experiential teaching and clarify the question of how to help improve the quality of teaching in today's smart and modern society

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≤ 18 years: 69, 48, 23; 85%), older adults (≥ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P < 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men

Research on Experiential Japanese Training Methods At Universities in Ho Chi Minh City

In the context that Vietnam and Japan are maintaining and strongly developing a good and comprehensive relationship in all fields, it is required that the Japanese-language workforce must have high professional qualifications and be able to compete with other markets from other countries in Vietnam in general and in Ho Chi Minh City in particular. The problem is that it is necessary to have new educational methods to help Japanese language students become interested in theoretical professional knowledge, create interest in learning, and above all, create opportunities to experience with future jobs so that students can have the right orientation later. The survey was conducted at two universities offering Japanese language training in Ho Chi Minh City. Research results show that this method is gradually being applied to training programs at the above schools, but it still does not bring the spirit of an experiential class due to difficulties in choosing content and form of training appropriate to the situation. This study aims to research on experiential Japanese training methods and propose some measures to apply to training programs of students studying Japanese language at universities in Ho Chi Minh City

Environmental education for the sustainable development of suburban communities in Ho Chi Minh City

Rapid urbanization contributes to a widening gap between the rich and the poor, which also increases the pressure on natural resources and the environment. Many industrial establishments emit uncontrollable hazardous substances and a lot of the waste belongs to the municipalities. Some of municipal waste is discharged into rivers and canals. In Ho Chi Minh City, the issue is not only a pressing issue of the city government but also affects the health of the people and the urban beauty. And as a result, it is currently the most polluting source for the city's canals. This study focuses on the assessment of environmental issues, environmental awareness and its impact on the livelihoods of suburban residents. By carrying out a survey, the research results show that many environmental problems have appeared quite serious and complicated developments. The article proposes some environmental education solutions for sustainable development with the people-focused principle in order to promote the responsibility of the people

Scheduling for a container supply chain to minimize costs using the meta-innovation approach

In this study, a problem of scheduling shipping lines for a container supply chain is addressed in order to minimize the costs of charging ships and the cost of maintaining the inventory of empty containers in the port by considering the time window of the port and the amount of fuel. This is a hard-NP problem and cannot be solved on a large scale with precise methods in a logical time. Therefore, to solve and optimize the model, a meta-innovative algorithm, genetic algorithm, has been used. Also, to increase the effectiveness of the genetic algorithm, the parameters of the algorithm are adjusted using the Taguchi method. Finally, a number of problems have been solved to show the performance of this algorithm and its computational results have been compared with the results obtained from GAMS software

Thermal conductivity and dynamic viscosity of highly mineralized water

Further development in the field of geothermal energy require reliable reference data on the thermophysical properties of geothermal waters, namely, on the thermal conductivity and viscosity of aqueous salt solutions at temperatures of 293–473 K, pressures Ps = 100 MPa, and concentrations of 0–25 wt.%. Given the lack of data and models, especially for the dynamic viscosity of aqueous salt solutions at a pressure of above 40 MPa, generalized formulas are presented here, by which these gaps can be filled. The article presents a generalized formula for obtaining reliable data on the thermal conductivity of water aqueous solutions of salts for Ps = 100 MPa, temperatures of 293–473 K and concentrations of 0%–25% (wt.%), as well as generalized formulas for the dynamic viscosity of water up to pressures of 500 MPa and aqueous solutions of salts for Ps = 100 MPa, temperatures 333–473 K, and concentration 0%–25%. The obtained values agree with the experimental data within 1.6%
