본 논문은 창극 <서편제>에서 자기반영성을 드러내는 장면들을 분석하였다. 이 작품은 판소리와 소리꾼의 이야기를 다루고 있으며, 창작 창극임에도 불구하고, 작창 없이 기존 판소리의 눈대목들을 짜깁기한 작품이라는 점이 독특하다. 이러한 특성들은 작품 속에서 다양한 자기반영적 장면들과 관련된다. 판소리에 대한 나르시시즘적 언급은 이 작품이 전통 판소리의 예술성을 계승한 것처럼 보이도록 만들고, 극중극과 역할놀이는 실제극과 실제 등장인물이 더 사실적으로 보이도록 해준다. 또한 <심청가>의 서사와 음악을 끌어 들여서, 관객 스스로 적극적으로 이 작품과 기존 판소리의 연결고리를 찾도록 한다. 즉 창극 <서편제>의 자기반영성은 환영을 파괴하기보다는, 새로운 환영을 낳기 위해 환영의 속임수 장치의 일부를 공개하는 방식으로, 보수적 자기반영성을 드러낸다.

Objective: This study aimed to investigate the effects of fluoride-containing acidic tea beverages on bovine teeth surfaces. Methods: The pH values and fluoride concentrations of 11 kinds of mineral water and 23 kinds of tea were measured. The fluoride-containing Seopyenje black tea beverages with pH 3.48 were chosen for the experimental group. Distilled water that did not contain fluoride and had the same pH value as that of the Seopyenje black teas served as the positive control. The Jeju Samdasoo mineral waters with neural pH (pH 7.52) and no fluoride were chosen as the negative control. Bovine teeth in each group were submerged for 10 minutes. Thereafter, surface microhardness of each bovine teeth was measured and the results were analyzed. Results: The pH value range was 6.94-8.09 ($mean=7.37{\pm}0.08$) for the 11 kinds of mineral water and 3.48-6.74 ($5.62{\pm}0.05$) for the 23 tea beverages. Titratable acidity of the Seopyenje black tea beverages was higher than that of the distilled water mixed with citric acid, and the pH was 5.5 and 7.0, respectively. The fluoride content of the 11 kinds of mineral water was 0-1.09 ppm ($mean=0.44{\pm}0.02ppm$) that of the 23 tea beverages was and 0-0.74 ppm ($0.64{\pm}0.06ppm$). In terms of enamel microhardness reduction of the bovine teeth, the tea beverages had the largest effects. There was no significant difference in microhardness reduction between the tea beverages and distilled water mixed with citric acid (P>0.05). Conversely, a significant difference was found between the kinds of mineral water and tea beverages, and also between mineral water and distilled water mixed with citric acid (P<0.05). Conclusions: Acidic tea beverages appeared to erode the surfaces of bovine teeth. The amount of fluoride in the tea beverages was not enough to inhibit erosion. Therefore, frequent intakes of acidic tea beverage are likely to increase erosion on the surfaces of bovine teeth, by affecting the enamel microhardness of teeth.
