State borders are the areas that are vulnerable to the degradation of national identity. The purpose of this study was to investigate the attitudes and the behavior of language use among the multi-ethnic Indonesian of predominantly Dayak, Malay, and Chinese who resided on the Indonesia-Malaysia border. The present research applied a qualitative ethnographic approach to document and to describe how a group of multi-ethnic communities participated in building their awareness, attitudes and practices of language as a national identity. The data were taken from 20 informants. They were teachers, students, local people, entrepreneurs, and state civil apparatus. The research found out that the ethnic groups on the border were highly aware of using Indonesian language as evidenced through a form of community involvement, volunteerism and social attitudes in civilizing Indonesian as the dominant language at the border. Their awareness was shown through their involvement, volunteerism, and social attitudes in developing Indonesian language as the dominant language in the border. It is argued that the involvement of all ethnic groups on the border affects positively on strengthening their attitudes and awareness in using Indonesian language.
The case of coronavirus disease (COVID-19) has become a global crisis. In addition, more variants of the virus have been discovered with easier transmission and more harmful effects. Thus, understanding the risk factors associated with the susceptibility and severity of COVID-19 is critical for disease control. This review article aims to describe the risk factors associated with the severity of COVID-19. This study uses the article review method from research results obtained through searching the journal sites Google Scholar, PubMed, ProQuest and ScientDirect in the 2020-2021 period. To find articles that match the inclusion criteria we used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) strategy. A total of nine studies met the inclusion criteria for this review. These nine studies were assessed for quality, data extraction and synthesis. Risk factors that contribute to the severity of COVID-19 are age, gender, chronic comorbidities, cardiovascular disease, diabetes, hypertension, kidney failure, cancer and a history of smoking. New findings, unvaccinated patients are at higher risk of severity. Risk factors associated with the severity of COVID-19 include a person's individual characteristics, co-morbidities, smoking history and unvaccinated.
