Nomophobia is rising among high school students, especially in light of the Covid-19 pandemic, such as social distancing, longterm online learning, and lack of social support. Many studies have also shown that students with high levels of nomophobia have a higher risk of stress. However, very few researchers are interested in studying loneliness as a mediation factor for the relationship between nomophobia and stress. This study investigated whether the loneliness factor is a mediator in the relationship between nomophobia and stress in Vietnamese high school students. Participants include 556 Vietnamese high school students. Participants completed the Nomophobia Scale, Depression Anxiety Stress Scales 21, The UCLA loneliness scale version 3. In this research, to test variable relationships, the mediation analyzing method by the PROCESS macro 3.5 will be applied. The research concludes that for Vietnam high school students, the mediating role of loneliness was identified in the relationship between nomophobia and stress. It is a suggestion through this research that nomophobia preventive and mitigating measures should reduce loneliness in students.

Objective: The aim was to examine the association between heterocyclic amines 2-amino-1-methyl-6-phenylimidazo pyridine (PhIP) and the risk of colorectal cancer (CRC) in Viet Nam. Methods: We performed a case-control study for 512 colorectal cancer patients with the histopathological confirmation and 1,096 hospital controls. We collected information on lifestyle, diet, and cooking methods from participants by trained interviewers using the validated questionnaires. We used data of PhIP concentration in cooked beef analyzed by the LC/MS/MS and cooking questionnaire to estimate the daily intake of PhIP. We divided the estimated amount of PhIP (ng/person/day) into three levels of non-intake (the reference), medium, and high to estimate the Odds ratio and 95% confidence interval (OR, 95%CI). Results: The median intake of PhIP (ng/person/day) was 18ng and 102.8ng for medium and high PhIP intake, respectively. There was a significant association between PhIP intake and the risk of colorectal cancer. The adjusted OR (95%C), high intake vs. non-intake, were 4.89 (3.03, 7.89), p_trend<0.01 for all participants, for men OR (95%C): 5.27 (2.83, 9.81), p_trend<0.01, for women OR (95%C): 4.58 (2.10, 10.01), p_trend<0.01. The significant positive association was also observed for the sub-sites of the colon (proximal and distant) and rectum cancers. Conclusions: We observed the positive association of PhIP contributed from cooked-beef and the development of CRC. Cooking methods related to the occurrence of PhIP and other types of heterocyclic amines in cooked-beef and other meats would be significant investigations.

The English language is one of the international languages used for communication and learning worldwide. In Vietnam, English is taught as a second language in schools from elementary to advanced levels. In learning a certain foreign language, the autonomy of learners has become a vital subject for the past 30 years. This research surveys the autonomy of non-language-majorstudents in learning English in Ho Chi Minh City University of Education. The quantitative research method uses descriptive statistics and T-test. A group of 258 students (61 males and 197 females) took part in answering two questionnaires on learners' autonomy in learning English and the roles of lecturers and students in developing learner-autonomy in learning English. The results showed that the students were not familiar with the term learning autonomy. However, students were aware that they played a fundamental role in improving this ability. They also believed that the lecturers determined their English learning process. Thence, we propose solutions for the non-language-majors to improve their autonomy in learning English.

The article discusses the correlation of the social emotional learning (SEL) components perceived by secondary school students in Ho Chi Minh City, Vietnam. The study results show that there is a close correlation among SEL components. Based on the findings, it is implied that the development of SEL competences for secondary school students is an integrated process requiring interactions among different components of the SEL model and forming the model itself via the changes of each component. Moreover, when one component is affected, the influence does not merely happen on that specific component, yet on the entire SEL model as it was a case for the participating secondary school students in this study.
