Purpose: This retrospective study evaluated the relationship between the timing of periimplantitis diagnosis and marginal bone level after a 5-year follow-up of non-surgical periimplantitis treatment. Methods: Thirty-three patients (69 implants) were given peri-implantitis diagnosis in 2008- 2009 in Seoul National University Bundang Hospital. Among them, 31 implants from 16 patients were included in this study. They were treated non-surgically in this hospital, and came for regular maintenance visits for at least 5 years after peri-implantitis treatment. Radiographic marginal bone levels at each interval were measured and statistical analysis was performed. Results: Timing of peri-implantitis was one of the significant factors affecting initial bone loss and total bone loss not additional bone after peri-implantitis diagnosis. Patients with cardiovascular disease and diabetic mellitus were positively influenced on both initial bone loss and total bone loss. Patients who needed periodontal treatment after implant placement showed a negative effect on bone loss compared to those who needed periodontal treatment before implant placement during entire periods. Implant location also significantly influenced on amounts of bone loss. Mandibular implants showed less bone loss than maxillary implants. Among surgical factors, combined use of autogenous and xenogenic bone graft materials showed a negative effect on bone loss compared to autogenous bone graft materials. Use of membrane negatively affected on initial bone loss but positively on additional bone loss and total bone loss. Thread exposure showed positive effects on initial bone loss and total bone loss. Conclusions: Early peri-implantitis diagnosis led to early non-surgical intervention for periimplantitis treatment, which resulted in the maintenance of the bone level as well as preservation of the implant.

We collected age determination cases which were done at Yonsei university dental hospital, department of oral medicine from 1976 to 1999 to analyze it's tendency among Koreans. We analyzed 435 clients cases which were stored by age estimation program from January 1993 to December 1999. The results are as follows: 1. There were no significant difference in the sexual distribution (male : 52.0%, female : 48.0%) and more than half percent (51%) were 20's and 30's. 2. Among the age determination clients, those who wanted to decrease their age (50.3%) and those who wanted to increase their age (49.7%) shows similar in number. And the former case were predominant in the female clients, but the latter case in the male clients. Also the clients below six years of age were predominant in the former case, but the clients more than sixty were predominant in the latter case. 3. The purposes of age correction showed different distribution for ages: job or employment for 20's and 30's, marriage for 20's, registration for school for below six, welfare and other social services for 50 and older. 4. Age was estimated by Nolla's growth stage for 12 and under, calcification of the second and third molar for 12~20, and for 20 and over, Takei's tooth abrasion model was used. 5. The alleged age was in accordance with the documents and other information given by clients, but in the 20.6% of the estimation cases, the alleged age was discarded. In the results of the analysis of age determination cases in Koreans, many of the cases resulted from our historical turbulence and social distinctiveness, causing an increase in the necessity for age correction in each age group. For more accurate determination for each age group, further studies with Koreans must be done continuously.

1987년 주식시장 붕괴와 경기전망변화

장희영,김권배 인하대학교 산업경제연구소 1997 경상논집 Vol.11 No.1

투자자들의 경기전망변화가 증권가격에 영향을 줄 것이라는 것은 이론적으로 의심의 여지가 없다. 하지만, 미래경기에 대한 전망은 일반적으로 서서히 바뀌기 때문에 경기전망의 변화가 증권가격에 미치는 영향을 실증적으로 분석하는 것은 결코 용이하지 않다. 이 점에서 1987년 10월 19일에 있었던 미국을 위시한 세계각국에서의 주식시장 붕괴는 실증적 분석을 위한 귀한 기회를 제공한다. 즉, 주식가격의 폭락으로 그해 10월 19일 하루동안 미국 투자자들의 손실액이 5,000억 달러에 이르렀는데, 이러한 재산손실의 결과 향후 경기에 대한 투자자의 전망이 급변하였기 때문이다. 이 논문에서는 1987년 10월의 주식시장 붕괴 전후의 채권 및 주식의 가격변화를 조사함으로서 투자자들의 경기전망변화를 실증적으로 보이고, 경기전망변화로 인한 주식가격에의 영향을 횡단면적인 분석을 통하여 조사하였다. 실증분석 결과는 다음의 두가지로 요약된다. 첫째, 주식시장 붕괴 전후의 채권수익율변화를 등급별로 조사한 결과 주식가격이 폭락한 다음날 채권위험 프레미엄(risk premi-um)은 급등하였는데, 이는 투자자들의 경기전망이 급격히 악화되었음을 의미한다. 둘째, 주식수익율에 대한 횡단면적 분석 결과는 기업의 신용도에 의하여 대표되는 재무상태에 따라 크게 다름을 보여주고 있다. 주가가 폭락한 다음날인 10월 20일부터 7일간의 누적수익율은 기업의 재무상태와 뚜렷한 양의 상관관계를 보여주고 있다. 예를 들어, 가장 좋은 재무상태를 가진 기업들(Aaa 혹은 Aa 신용도)의 경우 누적수익율은 평균 7.38%이었던 반면 가장 나쁜 재무상태를 가진 기업들(Ba 이하 신용도)은 - 19.69%의 누적수익율을 보였다. 이러한 발견은 재무상태가 나쁜 기업들은 경기가 나빠지거나 나빠지리라 예상되는 경우 가장 큰 타격을 입는 반면 경기가 좋아지거나 좋아지리라 예상되는 경우 가장 큰 혜택을 입을 것이라는 기업부실비용에 근거한 이론을 뒷받침해 주고 있다 This study examines daily bond prices as well as daily stock prices surrounding the stock market crash of 1987. An analysis of bond prices shows sudden substantial increases in the bond risk premiums for the several days following the "Black Monday", indicating an abrupt change in investors' perception of future business conditions. On the other hand, an analysis of the stock market reveals a strong association between the post-crash stock returns and firms' financial conditions. During the seven day period following "Black Monday", the average cumulative abnormal return for firms with Aaa or Aa credit rating is 27% higher than that for firms with Ba or lower rating. These results are consistent with the notion that the impact of a perceived economic downturn on stock values is related to firms' financial conditions.

전산화 단층촬영으로 평가한 교근에 대한 보툴리눔 A형 독소주사와 교합안정장치의 효과

The purpose of this study is to evaluate the effect of botulinum toxin type A on masseter muscle atrophy and the extent of masseter muscle affected from the injection site in relation to injection dose, with and without occlusal splint therapy through computed tomographic measurement. 32 volunteers were divided into four groups - group 25U (injection dose of 25 unit), group 25Us (injection dose of 25 unit with occlusal splint), group 35U (injection dose of 35 unit), group 35Us (injection dose of 35 unit with occlusal splint). Each group consisted of 8 people. 3 positions (position 1, 2, 3 - 10mm, 20mm and 40mm from the inferior border of the mandible, respectively) were selected for the evaluation of the masseter muscle change. The following results were obtained. 1. The thickness and the cross-sectional area of the masseter muscle had reduced in all groups except for the right side thickness at position 3 of group 25U and group 25Us, and the right side thickness as well as the left side cross-sectional area at position 3 of group 35Us. In group 35Us, the thickness and the cross-sectional area of the masseter muscle had reduced significantly in all positions (P < 0.05). 2. There was no significant difference in the masseter muscle change between the injection dose of 25unit and that of 35unit. 3. The groups with occlusal splint showed greater reduction of the masseter muscle thickness than the other groups (P < 0.05). From the above results, botulinum toxin type A injection together with occlusal splint therapy in the treatment of masseter muscle hypertrophy would be clinically effective.
