코로나19 시기 아동·청소년의 교육환경 변화와 경험에 관한 질적 연구
장혜림 ( Chang Hae-lim ),이세원 ( Lee Sewon ) 한국가족사회복지학회 2022 한국가족복지학 Vol.69 No.2
본 연구의 목적은 코로나19 이후 언론기사에서 보도된 아동·청소년의 교육환경의 변화를 살펴보고 취약계층 청소년의 경험을 심도 있게 고찰하는 것이다. 이를 위해 뉴스기사분석과 개별심층면접을 활용한 질적연구를 수행하였다. 뉴스 헤드라인 분석 결과 ‘코로나19, 모두에게 같지 않은 시간-학교가 텅 빌 때 누군가는 전진했고, 누군가는 멈춰있었다’라는 주제가 도출되었고, 개별심층면접 분석결과 ‘코로나19가 만들어준 터 안에서 제자리걸음’이라는 주제가 도출되었다. 이러한 분석결과를 바탕으로 코로나19와 같은 재난상황에서 아동·청소년의 교육 및 돌봄 환경 개선을 위한 사회복지실천과 정책을 제언하였다. The purpose of this study is to examine the changes in the educational environment of children and adolescents reported in media articles during the COVID-19 and to examine the experiences of vulnerable youth in depth. For this purpose, a qualitative study was conducted using news big data analysis and individual in-depth interviews. As a result of the news headline analysis, the topic ‘Corona 19, times not the same for everyone - Some moved forward when the school was empty, and some stopped’. In addition, as a result of the individual in-depth interview analysis, the topic of ‘Staying in place in the field created by COVID-19’ was derived. Based on these analysis results, social work practices and social welfare policies were proposed to improve the education and care environment for children and adolescents in disaster situations such as COVID-19.

<P><B>Purpose</B></P><P>The human <I>CAV1</I>-<I>CAV2</I> locus has been associated with susceptibility to primary open-angle glaucoma in four studies of Caucasian, Chinese, and Pakistani populations, although not in several other studies of non-Korean populations. In this study with Korean participants, the <I>CAV1</I>-<I>CAV2</I> locus was investigated for associations with susceptibility to primary open-angle glaucoma accompanied by elevated intraocular pressure (IOP), namely, high-tension glaucoma (HTG), as well as with IOP elevation, which is a strong risk factor for glaucoma.</P><P><B>Methods</B></P><P>Two single nucleotide polymorphisms (SNPs) were genotyped in 1,161 Korean participants including 229 patients with HTG and 932 healthy controls and statistically examined for association with HTG susceptibility and IOP. One SNP was rs4236601 G>A, which had been reported in the original study, and the other SNP was rs17588172 T>G, which was perfectly correlated (<I>r</I><SUP>2</SUP>=1) with another reported SNP rs1052990. Expression quantitative trait loci (eQTL) analysis was performed using GENe Expression VARiation (Genevar) data.</P><P><B>Results</B></P><P>Both SNPs were associated with HTG susceptibility, but the rs4236601 association disappeared when adjusted for the rs17588172 genotype and not vice versa. The minor allele G of rs17588172 was associated significantly with 1.5-fold increased susceptibility to HTG (p=0.0069) and marginally with IOP elevation (p=0.043) versus the major allele T. This minor allele was also associated with decreased <I>CAV1</I> and <I>CAV2</I> mRNA in skin and adipose according to the Genevar eQTL analysis.</P><P><B>Conclusions</B></P><P>The minor allele G of rs17588172 in the <I>CAV1</I>-<I>CAV2</I> locus is associated with decreased expression of <I>CAV1</I> and <I>CAV2</I> in some tissues, marginally with IOP elevation, and consequently with increased susceptibility to HTG.</P>

<P><B>Abstract</B></P> <P>The dissolution of CO<SUB>2</SUB>, a greenhouse gas most responsible for global warming, in seawater lowers its pH and increases its ionic strength. <I>Sulfurovum lithotrophicum</I> 42BKT<SUP>T</SUP>, a deep-sea chemolithotrophic bacterium, can fix high concentration CO<SUB>2</SUB>. In this study, we investigated the effect of pH and ionic strength variation of seawater on CO<SUB>2</SUB> fixation by this bacterium. For a stable and continuous fixation of high concentration CO<SUB>2</SUB> by <I>S. lithotrophicum</I> 42BKT<SUP>T</SUP>, the pH and ionic strength of the seawater-based medium should be 6.1–6.8 and <0.8M, respectively. The deviation of pH and ionic strength from these ranges was indicated by the appearance of lengthened and fattened cells whose length and diameter increased by 70–90%. These results imply that the harmful effect of dissolved CO<SUB>2</SUB> on marine ecosystem is due to the increase in ionic strength and decrease in pH of seawater.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
