Building Resilience and Social-Emotional Competencies in Elementary School Students through a Short-Term Intervention Program Based on the SEE Learning Curriculum.

This study explored the positive effects of a six-week Social-Emotional and Ethical Learning (SEE Learning) program on resilience and social and emotional competences, adapted for elementary students in Daegu, South Korea, a region strongly affected by the first outbreak of COVID-19. A total of 348 third- and fourth-grade students from 15 elementary schools participated, and the curriculum was tailored, emphasizing key areas such as resilience, attention, kindness, attention training, and compassion. Repeated measures analysis of variance (RMANOVA) tests showed statistically significant improvements between pre- and post-tests in resilience and its subscales, including self-efficacy, tolerance of negative affect, positive support relations, power of control, and spontaneity, as well as in social and emotional competencies, including emotional regulation, social skills, empathy, and social tendencies.

Enhanced production of carboxymethylcellulase of a marine microorganism, Bacillus subtilis subsp. subtilis A-53 in a pilot-scaled bioreactor by a recombinant Escherichia coli JM109/A-53 from rice bran.

A gene encoding the carboxymethylcellulase (CMCase) of a marine bacterium, Bacillus subtilis subsp. subtilis A-53, was cloned in Escherichia coli JMB109 and the recombinant strain was named as E. coli JMB109/A-53.

Purification and characterization of cellulase produced by Bacillus amyoliquefaciens DL-3 utilizing rice hull.

A microorganism hydrolyzing rice hull was isolated from soil and identified as Bacillus amyloliquefaciens by analysis of 16S rDNA and partial sequences of the gyrA gene, and named as B. amyloliquefaciens DL-3. With the analysis of SDS-PAGE, the molecular weight of the purified cellulase was estimated to be 54kDa.
