This study compared the short-term(4 months) clinical results of regenerative therapy with bioabsorbable membranes($BioMesh^{(R)}$) and bone allograft for the treatment of periodontal(intrabony and furcation) defects in smokers and nonsmokers.(16 smokers) 32 subjects with 92 defects participated in the study(46 in smokers and 46 in non-smokers). This study also evaluated a bioresorbable barrier with and without decalcified freeze-dried bone allograft(DFDBA). The 92 periodontal defects were randomly treated with either the resorbable barrier alone or resorbable barrier in combination with DFDBA following thorough defect debridement and root preparation with tetracycline. Each patient received both types of treatment modalities. Clinical examinations(probing depth, gingival recession, clinical attachment level, plaque index and gingival index) were carried out immediately before and 4 months after surgery. Significant(p<0.001) gains in mean attachment level were observed for both smokers(2.93mm) and non-smokers(3.30mm) but there were not significant difference between two groups. Similarly, significant reductions in mean probing depthshowed for smokers(4.52mm) and non-smokers(4.26mm). However, when comparing gingival recession, smokers were found to exhibit significantly poorer treatment results(1.59mm vs 0.96mm, p<0.05). Using the split-mouth-design, no statistically significant difference between the two modalities could be detected with regard to pocket depth reduction, gingival recession, or attachment gain. These results illustrate that the attachment gain is better in the non-smoker and the best in the non-smoker with the combination therapy of resorbable barrier and DFDBA than with resorbable barrier alone but smoking had no significant effect on clinical treatment outcome, even though smokers show more significant gingival recession. In addition, both treatments, either resorbable barrier plus DFDBA or resorbable barrier alone, promoted significant resolution of periodontal defects but the addition of DFDBA with a bioabsorbable membrane appears to add no extra benefit to the only membrane treatment.

The purpose of present study is to assess the effects of capsaicin topically applicated to the chronic periodontal pain suffering area. In the First study, twenty patients with chronic pain caused by mild periodontal disease were selected, and periodontal pack containing capsaicin(PPC) was attached to these patients gingiva around pain suffering area. Then the presence of discomfort had been recorded every ten minutes for the first 1 hour. After 1 hour again, It had been recorded according to the presence of pack and to the existence of pain. In the second study, twenty moderate periodontitis patients were selected. After subgingival curettage of two quadrant area, non-euginol periodontal pack or PPC were attached to the curetted gingival margins of them (Non-euginol pack bearing area and capsaicin pack bearing area is supposed to control group and test group respectively.), and the degrees of pain with time had been recorded eight times with 1 hour interval (at that day) or recorded once in a day (from the next day to the next appointment day). The results are as follows : 1. PPC has caused discomfort accompanied by burning sensation to the mild periodontitis patients with chronic pain. 2. PPC has given little effects to improve the pain after subgingival curettage of moderate periodontitis patients.

이 연구에서는 제주도의 관광관련 산업이 다른 지역에 비해 외부 충격에 더욱 취약한 속성을 갖고 있는지 여부를 검토하였다. 아울러 이와 같은 취약성으로 인해 외부 충격시 제주경제가 추가적으로 경험한 피해의 규모를 추정하였다. 최근 발생한 세월호 사건, 사드 사태 및 COVID-19 사태를 외부 충격으로 정의하고 분석한 결과, 제주도의 관광관련 산업은 이와 같은 외부 충격 발생시, 타 지역에 비해 추가적인 충격을 경험하는 것으로 나타났다. 이 분석결과는 제주도의 관광관련 산업이 여타 시도에 비해 전반적으로 외부 충격에 취약한 성격을 가지고 있음을 시사한다. 또한 이러한 관광산업의 취약성에서 기인하는 제주경제에의 추가적인 부담 규모를 지역산업연관표의 각종 유발계수를 이용하여 분석하였다. 그 결과 제주도 관광산업의 외부 충격에 대한 취약성으로 인해 실질 총산출, 부가가치 및 고용은 전국 평균에 비해 큰 폭으로 하락하는 것으로 나타났다. 대표적으로 제주도의 추가적인 실질 부가가치의 감소 규모는 충격의 종류에 따라 -0.48%에서 -2.91% 사이로 추정된다. 이 연구 결과는 제주도 관광산업의 충격에의 취약성을 실증적으로 검증하였다는 데 의의가 있다. 또한 이러한 제주도 관광관련 산업의 특성상 충격 발생시, 충격을 완화하고 관광관련 산업이 복원력을 가질 수 있도록 관광정책의 방향을 정립할 필요가 있음을 시사한다. This study examines whether the tourism-related industries in Jeju island are more vulnerable to external shocks than the other regions. In addition, we estimate the additional impacts that Jeju economy experiences during the shocks. Adopting three external shocks such as Sewol ferry accident, THAAD incident, and COVID-19 diffusion, we find that Jeju's tourism-related industries are generally more fragile to external shocks than the other regions. We also measure the additional declines in output, value added, and employment of Jeju island due to the shocks, using the regional input-output tables. The results of this study imply that the tourism-related industries in Jeju island are more vulnerable to external crisis shocks. Thus, policy makers in Jeju island need to prepare tourism-related policies that help mitigate the external impacts and recover from the shocks.
