도재소부전장관에서 금속이 노출되지 않고 도재만이 파절시, 구강내에서 직접 행할 수 있는 심미적 수복 방법으로서 복합성 수지를 이용한 수복 방법이 널리 이용되고 있는데 본실험의 목적은 도재와 광중합성 수지간의 접합강도를 비교 측정코저 함에 있다. 본 실험에서는 주사전자 현미경을 사용하여 도재의 부식액 (5% 불화수소산용액, Excelco's porcelain etching gel) 및 부식 시간(2.5분, 5분, 10분, 20분)에 따른 부식양상을 먼저 관찰하였다. 그다음 각기 다른 시간에서 부식 처리된 도재와 대조군으로서 미부식 처리된 도재에 광중합성 수지를 부착시킬시, 첫째 Silane coupling agent(Scotch-Prime)도포후 광중합성 수지를 결합 시켰고 둘째 bonding agent(Scotch bond)도포후 광중합성 수지를 결합시켰으며 셋째 Silane coupling agent(Scotch-Prime)에 bonding agent(Scotch bond)를 도포후 광중합성 수지로 결합 시킨후, 인장강도 측정기 (Shimadzu universal testing machine)를 사용하여 결합력을 측정한 결과 다음과 같은 결론을 얻었다. 1. 부식처리된 도재가 미부식 처리된 도재 보다 결합력이 높았다. (p<0.05, P<0.001) 2. 부식 처리된 도재나 미부식 처리된 도재에 있어서 silane coupling agent 도포후 bonding agent로 처치한 경우 가장 결합력이 높았으며 그다음 silane coupling agent로 처치한 경우, bonding agent로 처치한 경우의 순이었다. 3. 도재부식 시간의 증가에 따른 결합력의 차이는 5% HF용액으로 부식 처리된 도재와 Excelco로 부식 처리된 도재에 있어서 5분 정도 까지는 결합력의 증가를 보였으나 그 후에는 결합력에 있어서 거의 증가하지 않는 양상을 보였다. 4. Excelco로 부식 처리된 도재와 5% HF 용액으로 부식처리된 도재간의 결합력 차이에 있어서 bonding agent만으로 처치한 경우에는 두결합력 사이에 서로 유의한 차이를 보이지 않았으나 (P>0.5) silane coupling agent만으로 처치한 경우와 silane coupling agent 도포후 bonding agent로 처치한 경우에는 두결합력 사이에 서로 유의한 차이를 보였다. (P<0.05, P<0.001) 5. Excelco로 부식처리된 도재가 5% HF 용액으로 부식처리된 도재보다 부식정도가 더 현저하였다.
Demethylchlorotetracycline이 백서의 관상봉합 발육에 미치는 영향에 관한 실험적 연구

To study some informations on the morphogenesis and developmental process of the coronal suture in rats, the author performed daily oral administrations of demethylchlorotetracycline, a kind of tetracycline group, in the amount of 30mg/kg of body weight to the female rats from the 7th day of pregnancy to the time of delivery. Microscopic evaluation was undertaken on the fetal rats in the experimental group. The subject of this experiment were defined to the fetal rats of each group at 1st, 3rd, 7th and 14th day after birth. All these fetal rats were sacrificed and the heads were removed. All the tissue sections were fixed with $10\%$ formalin, Bouin' and Carnoy' solution and then stained by Hematoxylin-Van Gieson stain, or Feulgen and Rossenbeck, Periodic acid Schiff, and prepared for alcian blue reaction. The results were as follows; 1. The directions of osteogenic fibers were arranged irregulary during first 3 days, but after the 7th day they tended to change radial directions like control group. 2. The density of deep stained cells by Feulgen-Rossenbeck reaction were shown leu in the experimental group than that in the control group in first 3 days, but there was shown no significant difference between both groups after the 7th day. 3. PAS reaction in early stage was generally negative in the experimental group unlike as in the control group, but diffuse reaction was observed in the loose middle zone like as in the control group after 14th day. 4. Alcian blue reaction was negative in cambial zone, and slightly positive in uniting zone compared with control group in early stage. After 14th day, however, there was observed a tendency of moderately positive reaction.

수지상 지방종은 활액막에서 지방 조직이 융모상으로 증식하는 질환으로, 발생 원인으로 외상, 반월판 손상, 염증, 감염, 퇴행성 변화, 종양 등이 알려져 있다. 이 질환에 대한 보고는 매우 드물다. 저자들은 관절경적 수술로 양호한 치료 결과를 보인 슬관절 전 구획에서 발생한 수지상 지방종 1예를 보고한다. Lipoma arborescens is a villous proliferation of fatty tissue in the synovial membrane, and known causes are trauma, meniscal injury, inflammation, infection, degenerative change, tumor, and so forth. The reported cases are extremely rare. We report a case of lipoma arborescens developed in all compartments of the knee joint, and treated well with arthroscopic surgery.

The purpose of this study is to explore the effects of medical service quality and location of orthodontic clinic on the customer satisfaction and a subsequent intention to revisit, recommentation based on quantitative analysis. The data were gathered from outpatients who were treated by orthodontic clinic in the dental field. They were asked to assess the medical service quality, ranging from the location, customer satisfaction, intention to revisit, and recommendation. A total of 398 usable questionnaires were used for the survey. These hypothesized relationships concerning many kinds of factors were verified by covariance modeling, using SPSS15.0 and AMOS 7.0 programs. The methods for the study were confirmatory and covariant structural analyses. The results of the study are as follows First, medical service quality had a significant effect on customer satisfaction, Second, location of orthodontic clinic had a significant effect on customer satisfaction. Last, customer satisfaction had a significant effect on the intention to revisit and recommendation to other patients.
