The need for values education programs for both pre-service teachers and in-service teachers in Vietnam

This paper investigates the perceptions of pre-service teachers and in-service teachers regarding the concept of 'values education' and the preparation of values education in professional programs in Vietnam. Furthermore, the pedagogical strategies employed by teachers in addressing values education situations in their classrooms are explored. A qualitative research design was employed, involving interviews with forty-three pre-service teachers from a university. Additionally, eighteen teachers from two different high schools were interviewed, and their teaching sessions, along with school assemblies, were observed. The findings reveal that values education is primarily understood as the instruction of living skills and moral education. There is a lack of conceptualization and knowledge regarding values education among the participants. Both pre-service teachers and in-service teachers did not receive formal values education programs during their university education, and the support provided by schools in this regard was limited. Teachers tended to integrate values education into subjects randomly and subjectively, without employing advanced strategies. Inconsistencies in implementation and challenges associated with teaching values were observed. Highlighting an urgent necessity, this article emphasizes the imperative need for values education programs tailored for both pre-service and in-service teachers in Vietnam. It underscores the significance of adequately equipping teachers to effectively address values education in their classroom

Ambient-temperature conversion of metakaolin to sub-micron LTA zeolite and its copper ion removal efficiency

Nowadays “green” processes such as room temperature processes are interested in new researches for production of practical-important solid materials. Zeolitic LTA materials are commonly prepared by hydrothermal transformation using sodium hydroxide (NaOH), sodium aluminate (NaAlO2), and sodium metasilicate (Na2SiO3) at high temperatures (95 – 100 ◦C). In this study, sub-micron zeolite LTA was prepared at ambient temperature from metakaolin which is easily obtained from kaolin mineral. The prepared materials were characterized using various methods, including XRD to identify their structure, SEM and EDX to analyze the shape and proportional components of the elements, and the N2 adsorption–desorption method to determine the surface area and pore volume. Regarding the Cu2+ ion adsorption capability of the synthetic zeolite, the experimental results revealed that the sub-micron zeolite LTA has potential applications in practice because its adsorption rate exceeds that of the commercial zeolite and the rate constant of the second–order kinetics model of the prepared zeolite was 1.7 times higher than that of the commercial zeolite

ĐẶC ĐIỂM HÌNH THÁI VÀ ĐẶC ĐIỂM VI HỌC CỦA LOÀI BA KÍCH TÍM (Morinda officinalis How.) THU HÁI TẠI TỈNH THỪA THIÊN HUẾ

Morinda officinalis How. is a medicinal plant that has been studied and used for a long time. Previous studies on M. officinalis primarily focused on the source in the northern provinces of Vietnam. This study is the first one on the botanical characteristics, including morphology, anatomy, and powder microscopy of M. officinalis in Thua Thien Hue province. Morphological and microscopic characteristics were determined by comparing the shape and double-staining and observing under a microscope through 10× and 40× objective lenses. The results show the similarities and differences of M. officinalis in Thua Thien Hue and other regions of Vietnam. Particularly, the root of M. officinalis in Thua Thien Hue has a higher percentage of usable parts than other M. officinalis species in northern regions. Furthermore, the results of the study provide scientific data for learning and investigating the morphological and microscopic characteristics of M. officinalis in Thua Thien Hue.Ba kích tím (Morinda officinalis How.) là một loài dược liệu quý được nghiên cứu và sử dụng từ rất lâu đời.

Successful Psoriasis Treatment Using NB-UVB with Methotrexate: The Vietnamese Experience

AIM: To compare the effectiveness of narrowband ultraviolet B (NBUVB) and oral methotrexate (MTX) to oral MTX alone in Vietnamese psoriasis patients, from May 2016 to May 2018. METHODS: We conducted a non-randomized trial on 70 patients with plaque-type psoriasis of moderate to severe. Thirty-five patients apply NBUVB once/day in 5 days/week for 4 weeks plus oral MTX 7.5 mg/week and 35 patients oral MTX 7.5 mg/week and both two groups treatment for 3 months. The extent of the lesion was assessed by the Psoriasis Area and Severity Index (PASI). RESULTS: The proportion of decreasing PASI was comparable (68.49% in NBUVB and MTX versus 57.62% in MTX alone); p &lt; 0.05. Inside, good 28.58%, moderate 68.57% and poor 2.85% in NBUVB and MTX better than good 2.85%, moderate 71.4% and poor 25.72% in MTX alone; p &lt; 0.05. The recurrence rate after 24 months of the NBUVB and MTX group (42.9%) was lower than the MTX alone group (71.4%); p &lt; 0.05. CONCLUSION: NBUVB and oral MTX have affected treatment with chronic plaque psoriasis better than oral MTX alone

Antibiotic use and prescription and its effects on Enterobacteriaceae in the gut in children with mild respiratory infections in Ho Chi Minh City, Vietnam. A prospective observational outpatient study.

BACKGROUND AND OBJECTIVES: Treatment guidelines do not recommend antibiotic use for acute respiratory infections (ARI), except for streptococcal pharyngitis/tonsillitis and pneumonia. However, antibiotics are prescribed frequently for children with ARI, often in absence of evidence for bacterial infection. The objectives of this study were 1) to assess the appropriateness of antibiotic prescriptions for mild ARI in paediatric outpatients in relation to available guidelines and detected pathogens, 2) to assess antibiotic use on presentation using questionnaires and detection in urine 3) to assess the carriage rates and proportions of resistant intestinal Enterobacteriaceae before, during and after consultation. MATERIALS AND METHODS: Patients were prospectively enrolled in Children's Hospital 1, Ho Chi Minh City, Vietnam and diagnoses, prescribed therapy and outcome were recorded on first visit and on follow-up after 7 days. Respiratory bacterial and viral pathogens were detected using molecular assays. Antibiotic use before presentation was assessed using questionnaires and urine HPLC. The impact of antibiotic usage on intestinal Enterobacteriaceae was assessed with semi-quantitative culture on agar with and without antibiotics on presentation and after 7 and 28 days. RESULTS: A total of 563 patients were enrolled between February 2009 and February 2010. Antibiotics were prescribed for all except 2 of 563 patients. The majority were 2nd and 3rd generation oral cephalosporins and amoxicillin with or without clavulanic acid. Respiratory viruses were detected in respiratory specimens of 72.5% of patients. Antibiotic use was considered inappropriate in 90.1% and 67.5%, based on guidelines and detected pathogens, respectively. On presentation parents reported antibiotic use for 22% of patients, 41% of parents did not know and 37% denied antibiotic use. Among these three groups, six commonly used antibiotics were detected with HPLC in patients' urine in 49%, 40% and 14%, respectively. Temporary selection of 3rd generation cephalosporin resistant intestinal Enterobacteriaceae during antibiotic use was observed, with co-selection of resistance to aminoglycosides and fluoroquinolones. CONCLUSIONS: We report overuse and overprescription of antibiotics for uncomplicated ARI with selection of resistant intestinal Enterobacteriaceae, posing a risk for community transmission and persistence in a setting of a highly granular healthcare system and unrestricted access to antibiotics through private pharmacies. REGISTRATION: This study was registered at the International Standard Randomised Controlled Trials Number registry under number ISRCTN32862422: http://www.isrctn.com/ISRCTN32862422
