Social-emotional capacity is considered a fundamental capacity for personal development of each person and each age group. For students of early childhood education, social - emotional capacity not only helps students have many advantages in learning but also creates good conditions to develop their careers in the future. The article presents the current state of social-emotional capacity of 448 first - year students majoring in Preschool education in the provinces of Lang Son, Nghe An, Hue, and Da Nang. The study used the social - emotional capacity questionnaire developed by Zhou and Ee (2012). The results show that the social - emotional capacity of first-year students of early childhood education is quite low and uneven among the components of this capacity. At the same time, the current study proposes three solutions to improve students' social - emotional capacity.

In this study, we synthesized 5-alkyl/arylidene-2-(morpholin/thiomorpholin-4-yl)-1,3-thiazol-4(5H)-one through a one-pot reaction using all starting materials in a microwave oven. The presence of the solid base MgO catalyzed the reaction in the eco-friendly solvent of ethanol as a green chemistry approach owing to the noticeable advantages of short reaction times to save energy and less toxic starting materials for environmental friendliness. This indicates that the one-pot reaction makes the process simpler, in which the reaction time (1 h) is shorter than that of conventional methods (10 h). The yield of the reactions reached 55–76% for 18 final products consisting of 17 derivatives of morpholine or thiomorpholine with various aldehydes and one extended moiety of the primary amine, of which 13/18 final compounds were new. The purification procedure was performed without using polluting solvents. The structures were confirmed using IR, 1H-NMR, 13C-NMR, and MS analyses.

Trong các nghiên cứu này, 16 nguyên tố: Mg, Ca, Mn, Cu, Na, K, As, Sc, Fe, Co, Zn, Se, Rb, Cs, Hg trong bảy loại cá biển và bảy loại cá nước ngọt phổ biến thu thập tại Nha Trang, Phan Rang và Đà Lạt đã được xác định bằng phương INAA. Tỷ lệ dinh dưỡng của các nguyên tố dinh dưỡng được tính toán so sánh với chế độ dinh dưỡng tham khảo (RDA), lượng tiêu thụ vừa đủ (AI) của IOM và tỷ lệ độc hại của các nguyên tố As và Hg được tính toán so sánh với tỷ lệ tiêu thụ chấp nhận được của WHO. Kết quả cho thấy tỷ lệ dinh dưỡng và độc hại trong các loại cá là thấp hơn so với các tiêu chuẩn của IOM và WHO ngoại trừ tỉ lệ độc hại của as trong một số loại cá. Tỷ lệ độc hại của Hg trong các loại các ngừ, cá lóc cao hơn các loại cá khác nhưng vẫn thấp hơn giới hạn tiêu thụ của WHO.

Introduction: Autosomal recessive renal tubular dysgenesis (ARRTD) is a rare genetic disorder with a very high mortality rate. The typical symptoms of the disease during pregnancy are oligohydramnios, anhydramnios, and nearly all affected fetuses die after birth or have a stillbirth in late gestation, which can adversely increase maternal risks., Methods: Oligohydramnios/anhydramnios can make both amniocentesis for diagnostic testing and morphological evaluation via ultrasound more difficult. In cases of oligohydramnios/anhydramnios suspicious for urinary tract anomalies, amnioinfusion is a meaningful technique that facilitates sampling of amniotic fluid for genetic diagnosis., Results: We report two cases of fetuses with anhydramnios and invisible urinary bladder. Clinical exome sequencing from amniotic fluid revealed a biparentally inherited homozygous pathogenic nonsense ACE variant c.2503G 〉 T [p.Glu853Ter] in proband 1 and a biparentally inherited homozygous pathogenic nonsense ACE variant c.2992C 〉 T [p.Gln998Ter] in proband 2. The prognosis was poor and the patients elected to terminate the pregnancies. Additional post-mortem histopathological examination from the renal tissue of the second fetus showed renal tubular hypoplasia., Conclusion: To our knowledge for the first time, we describe the prenatal diagnosis of ARRTD in Vietnam, and highlight the benefit of detecting ACE variants associated with ARRTD in fetuses with oligohydramnios/anhydramnios through amnioinfusion and amniocentesis, which improves genotype-phenotype correlations and provides valuable information for reproductive counseling., (© 2023 The Authors.

Antibiotics like rifampicin are often persistent in the environment. When entering the water, it causes antimicrobial resistance that affects the ecosystem and accumulates in the aquatic organisms and affects human health through the food chain. In this study, titanium dioxide was doped with neodymium (0.01 to 0.8%) using the sol-gel hydrothermal method. TiO 2 /Nd was then coated on rice husk ash to produce a modified TiO 2 /Nd/rice husk ash material containing 0.36% (w/w) Nd. The structural characteristics and photocatalytic properties of the materials were analyzed by X-ray diffraction, energy dispersive X-ray, transmission electron microscopy, scanning electron microscopy, forbidden zone energy, and specific surface area. The TiO 2 /Nd material exhibited a higher photocatalytic decomposition capacity than TiO 2 and depended on the Nd content. The rifampicin removal efficiency of TiO 2 /Nd materials with 0.36 to 0.80% Nd contents was approximately 40% higher than that of TiO 2 /Nd containing 0.01 to 0.28% Nd. A new photocatalytic TiO 2 /Nd/rice husk ash material was developed to decompose rifampicin. The rifampicin-degrading efficiency of TiO 2 /Nd and TiO 2 /Nd/rice husk ash material reached approximately 86 and 75%, respectively, within 90 min under sunlight. Although a lower efficiency was obtained, the TiO 2 /Nd/rice husk ash material was selected to degrade rifampicin residue in water via the photocatalytic process (under sunlight) because of its advantages such as requirement of a small amount and easy recovery. In the rifampicin removal process, k values were found to match the zero- and first-order kinetics. In particular, for TiO 2 /Nd and TiO 2 /Nd/rice husk ash under solar irradiation, R 2 values reached approximately 0.98.
