문화자본, 사회자본 및 학업성취도 간의 구조적 관계 -교직이수자를 중심으로-
김종학 한국미래교육학회 2021 미래교육연구 Vol.11 No.4
The present study attempted to verify the mediating effect of social capital in the relationship between cultural capital and academic achievement for university students. Toward this end, the study included survey data collected from 270 students from national universities in the analysis. The collected data was analyzed using the SPSS 22.0 and AMOS 22.0 statistical programs. The results of the present study can be summarized as follows. First, there was a significant positive correlation between the overall variables of cultural capital, social capital, and academic achievement. In particular, the greatest correlation was exhibited between social capital and academic achievement with regard to the relationship between dependent variables. Second, social capital appeared to fully mediate the relationship between cultural capital and academic achievement. This implies that students can increase their academic achievement by increasing their level of social capital, which is slightly more fluid than cultural capital in an embodied state, which is acquired while being naturally exposed to such a culture since childhood.

Renin-angiotensin-system(RAS) has been thought to have a pivotal role in renal injury mechanism. Many reports state that the inhibition of RAS prevents the progression of renal disease in 5/6 nephrectomized rats as a typical chronic renal failure model. Angiotensin converting enzyme inhibitor blocks the conversion from Angiotensin I to Angiotensin Ⅱ (A-Ⅱ ), and ATI RA inhibits the action of A-Ⅱ at the level of AT1 receptor. Therefore the PRA and A-Ⅱ level may be influenced independently by each treatment modality with these drugs. In this study, the influence of long term treatment with ACEI or AT1RA in these models on systolic blood pressure, PRA, and A-Ⅱ level was evaluated. Male Sprague-Dawley rats weighing 270-300 grams were anesthesized with thiopental sodium(50 mg/kg) and underwent right nephrectomy and partial(approximately two thirds) infarction of the left kidney by ligation of two-three segmental arterial branches. The rats were divided into four groups : sham group, control group, 5/6 subtotal nephrectomized and ACEI treated group (enalapril 100 mg/L in drinking water), 5/6 subtotal nephrectomized and ATIRA treated group (losartan, 200 mg/L in drinking water). They were treated for twelve weeks. In the twelve weeks, both groups treated with ACEI and AT1RA ingestion demonstrated a significant decrease in systolic blood pressure(165±23 vs. 132±9, mmHg, control vs. ACEI, M±SEM, p<0.05, 165±23 vs. 124±7 mmHg, control vs. ATIRA, M±SEM, p<0.01) compare to the control group. In both group treated with ACEI and AT1RA showed a significant increase in PRA(ACEI ; 7.2±2.9, AT1RA ; 4.7±0.4, control ; 2.7±1.1, sham ; 2.7±1.4, ng/ml/hr, ACEI vs. control and sham, M±SEM, p<0.05). However no significant differences were found in the sham vs. control(p>0.05), and in ACEI vs. control. The plasma A-II level was significantly increased in AT1RA treated group compared to sham and ACEI treated group(2,753±543 vs. 484±169.3, ng/ ml, AT1RA vs. Sham, p<0.01). In conclusion, treatment with ACEI and AT1RA for twelve weeks normalized systolic blood pressure, proteinuria and increased PRA compared to the control group; whereas plasma A-II level was increased only by AT1RA treatment.

A cDNA clone (GenBank accession no. CF924621) homologous to aluminum inducedprotein gene was isolated and characterized from Codonopsis lanceolata(ClAIP). The ClAIPis 906 nucleotides long and has an open reading frame of 711 bp with a deduced amino acidsequence of 236 residues. The ClAIPshows high homology to A. marina(84%), G. hirsutum(83%), V. radiata(83%), A. thaliana(80%), B. napus(78%) and T. aestivum(68%). Thededuced amino acid sequence of ClAIPalso has homology to the N-terminal end of plant Asnsynthetase. This region does not contain the active sites of the enzyme and the significance ofthis conservation is currently not clear. To investigate the expression of ClAIP againstseveral heavy metal stresses, we treated the sliced tap root of C. lanceolatawith variousheavy metals. The expression of ClAIPwas increased by 25 uM Al2(SO3)4 in proportion toincubation time and also increased by 50 uM CdCl2.
