본 실험의 목적은 치아 회분이 입자 크기에 따라 골형성에 어떠한 영향을 주며 순수 합성수산화 apatite인 calcitite와는 어떠한 차이가 있는가를 평가하기 위하여 수행하였다. 이를 위하여 200mesh와 40mesh의 치아 회분말과 40mesh calcitite를 잡종견의 신선한 발치와에 매식후 1주, 2주, 3주, 4주에 각각 희생하여 임상, X-선상 및 현미경적으로 관찰한 바 다음과 같은 결론을 얻었다. 1. 모든 경우에 조직의 거부반응이 없었다. 2. 40mesh치아 회분의 경우가 200mesh의 치아회분의 경우 보다 골 형성 능력이 현저히 높았다. 3. 40 mesh 치아회분과 calcitite 모두 비교군에 비하여 골 형성이 지연되었다. 4. 40 mesh 치아 회분과 calcitite의 골 형성 능력은 유사하였다.

In this article, the thermosyphon type heat sink using the methanol as a working fluid has been experimentally investgated. Experimental tests on the various working fluid charging rates, input power, and the various air velocites of thermosyphon type heat sink have been carried. For the above experimental condition, the thermosyphon type heat sink using the methanol as a working fluid has evaluated in terms of the thermal resistance. The cooling performance of thermosyphon type heat sink showed superior about 30% to extrudede heat sink In this study optimized performance has been founded that the working fluid charging rates have been thirty five percent of the total volume.

In this study, ice slurry generator using air cylinder was designed and manufactured to investigate the heat transfer characteristic of the ice slurry generator. The ice slurry generator has the same shape as the shell-and-tube type heat exchanger. Refrigerant is flowing in the shell side and ethylene glycol solution in the tube side. The experiment was conducted on performance of ice slurry generator using air cylinder with standard condition and the results are plotted on the time scale. The experimental tests on the various concentration of ethylene glycol solution, the various solution velocity in the tube side and the various tube size have been carried. For the above experimental conditions, ice making characteristics of the ice slurry generator are evaluated in terms of the overall heat transfer coefficient. And the experimental results show that the overall heat transfer coefficient of the system is increased as the tube size and the concentration of ethylene glycol decreases.

In this study, ice making characteristics are experimentally investigated for the ice slurry generating system which is pneumatically operated. The ice slurry generator has the same shape as the shell-and-tube type heat exchanger. Refrigerant is flowing in the shell side and ethylene glycol solution in the tube side. The experimentations are conducted under the various test conditions such as aqueous solution concentration, flow rate of solution and frequency of cylinder stroke. For the above experimental conditions, ice making characteristics of the slurry ice generating system are evaluated in terms of the overall heat transfer coefficient and the amount of slurry ice generation. And the experimental results show that the heat transfer rate of the system is increased as the flow rate of aqueous solution increases and the concentration of ethylene glycol decreases.

Despite the development of new impression technique for complete lower dentures, the achievement of adequate retention, support, and stability still remains a devinite problem for many patients. Correct extension of the complete lower denture base is not only essential for the development of retentive forces to best advantage, but it is a prerequisite of maximum stability. But the correct design of the lingual flange of a complete denture continues to challenge the skill and imagination of the dental profession. Owing to limited mobility of the muscles, frena, and membranous attachments, the buccal and labial flanges are more easily managed. Unfortunately, the floor of the mouth rises and falls like the tides of the sea, lengthening and widening the protean lingual vestibule. Therefore, in this articlewe discussed (1) the anatomy of the lingual space and principles underlying lingual design, (2) a technoque for achieveing an optimum lingual flange. If, in the construction of difficult lower dentures, the consideration is given to the dynamic nature of the denture space, it is easier to make satisfactory lower dentures.

Authors had the patient wear the occlusal stabilization splint for 10 weeks to regain a vertical jaw relation that is consistent with the contracted length of the muscles for the patient who had a lost verical dimension caused by the severe attrition and abrasion of all teeth of the upper and lower dental arch. The purpose of this study was to know the PMS concept and its technique to provide an excellent and practical method for determining an occlusal plane that will fulfill all the requirements of a correct occlusion. Immediately afger equalizing the muscle activities of the right and left closing muscles using EM2 to the patient wearing the occlusal splint, the full mouth rehabilitation of the PMS concept and its technique was done. From this clinical study the following results were obtained. 1. The application of using EM2 was necessary to equalize the muscle activities of the right and left closing muscles. 2. The plane of occlusion of the lower posterior teeth was established by incorporating a Curve of Spee which is approximately the arc of a four inch circle using the Broadrick occlusal plane anlayzer. 3. The lingual surface of the maxillary anterior teeth was established with the long centric which had no contact at centric relation occlusion and had contact at centric occlusion without the change of the vertical dimension. 4. The occlusion of the masillary posterior teeth was established by application of the concept of a long dentric and the group functioned occlusion, utilizing a F. G. P technic in the patient's mouth. 5. There was not andy occlusal interferences between the centric relation occlusion and the centric occlusion under every mandibular movement and good results were obtained functionally and esthetically.
