There is no definite criteria for the determination of the level of amputation in ischemic limb or diabetic foot. So, We propose our update criterias for this problem as another good method, which are color doppler sonography as a noninvasive method and angiographic imaging as a more accurate but invasive method for the vascularity and its supplimentation in ipsilateral lower extremity as well as Wagner's ischemic index. We are concluded from our experience, as these; 1. Color doppler imaging is a kind of a good method for the determination of the level of amputation in ischemic limb or diabetic foot of lower extermity, even than Wagner's ischemic index. 2. The wound healing of diabetic foot is more difficult than any other foot disease such as Buerger's disease or atherosclerotic vascular disease in our experience.

The purpose of this study was to assess relative tooth abrasivity and to measure effective fluoride concentration of dentifrices selling in Korea for help consumer's selection of suitable dentifrice. Assessment of the abrasion on tooth produced by different dentifrices were carried out on bovine teeth in the laboratory and tested by radioactive dentin abrasion method. And total soluble fluoride concentrations within the dentifrices was determined using fluoride ion selective electrode with standard curve obtained from standard solutions of known fluoride concentration. 10 dentifrice samples were stored at 49t for 15 weeks and the measurements were made for each dentifrice in 1 week, 2 weeks, 3 weeks, 13 weeks and 15 weeks and 11 dentifrice samples were stored at 40.6C for 3 weeks and the measurements were made for each dentifrice in 1 week and 3 weeks. Tooth abrasivity of selling dentifrices is suitable for toothbrushing but dentifrice which recommended for patient who have tooth abrasion or erosion was somewhat high abrasivity level. Effective fluoride concentrations of selling dentifrices were maintained generally optimal level. But some dentifrices contaning CaCO_(3), as abrasive were decreased as time elapsed. It was suggested that relative tooth abrasivity must be marked on package and fluoride level should be maintained acceptable level in dentifrices for consumer's selection of suitable dentifrice.

It is generally agreed the best clinical results in treatment of injuries of the ankle are obtaind by anatomical restoration of the joint. For objective measurements of tibiotalar joint, some investigators used different criteria and defined the specific reference points under variable angle of internal rotation Ant- Post. Projection. But, occasionally we didn't acquire the accurate roentgenographic finding that was suggested by investigators. so, we check the varible angle of internal rotation film in addition to angle suggestion by investigators and compare the criteria between them. 1. There was no significant difference to measure the accuracy of medial clear space in according to variable rotation angle. 2. The overlapping distance of tibiofibula syndesmosis decreased by increasing internal rotation angle, but was not under 1mm(ie, index of injury) 3. To measure the weber's 3 criteria, we need to check the variable internal rotation ankle, if necessary. 4. We acquired the normal range of measurement about Tile's 2 criteria by variable internal rotation angle.

KS and ISO have proposed several evaluation methods of conventional machine tools. Even though the accuracy of the tools can be evaluated with those methods, there are still no proper evaluation methodsofhigh speed machining. Because it is hard to evaluate characteristics of high speed machining such as decrease of cutting temperature, cutting force, and reduced machining time. Therefore, new evaluation method for high speed machine should be developed. In this paper, several shapes of model have been proposed to evaluate cutting accuracy of high speed machine.

경골 Pilon 골절의 수술적 치료 : 제한적 내고정술을 겸한 외고정술과 관혈적 정복 및 내고정술의 비교 Comparison of Limited Open Reduction and External Fixation with Open Reduction and Internal Fixation

The pilon fracture result from axial compression and rotational forces causing variable degrees of metaphyseal disruption, articular damage and malleolar displacement. It's managements are closed reduction and plaster immobilization, skeletal traction, fibular stabilization alone, limited open reduction and external fixation, open reduction and internal fixation, primary arthrodesis, and even immediate amputation. Recently limited open reduction and external fixation has been proved to provide good clinical results for the severely comminuted or open pilon fractures. Authors reviewed eighteen cases of the pilon fractures from March 1991 to February 1997. Among them eight cases were treated with limited open reduction and external fixation, and ten cases were treated with open reduction and internal fixation. In conclusion, limited open reduction and external fixation has shown better results than open reduction and internal fixation in severely comminuted or open pilon fractures for wound healing and preventing of other complications.

Until recently, the treatment of tibia shaft fractures become one of the most controversial subjects in orthopaedic surgery. One groups insisted that this fractures should primarily be treated with conservative methods, the other groups open reduction & internal fixation has been recommended. Among the nature of fracture patterns, displaced closed or grade 1 open, spiral, oblique and transverse fractures(types Al, A2 and A3 according to Johner's and Wruhs's classification) are still controversial about treatment method. Some auther's have been compared both methods of treatment without detailed criteria. Recently Den Outer compaired both treatments with detaliled criteria and reported that conservative treatment are more preferable. We also compaired retrospectively both treatment methods and the obtained results were, except more complications with conservative treatment, encouraging to us for choosing operative treatment. That is, less malunion and shortening, less delayed union and less disability after fracture healing.

論語의 藝術觀

The Analects are basic documents of the classical aesthetics in the Far East. The Confucius's viewpoint described in his Analects is based on the intellectuality and human philosophy by which reverence towards tradition and the restrictive incompleteness of human mind as well as the insight, distinguishability, controlability and realizability of human mind are framed. Therefore, the aesthetics included in the Analects is the principle of moderation, harmony and control. This, as the classical aesthetics, can correspond with the classical aesthetics of Europe. This aesthetics is based on Confucius's reverence towards tradition, his philosophy on human being as well as his intelligence. Also it can be said that Confucius's viewpoints on poetry, music and the fine arts are based on the aesthetics of moderation, harmony and control. The idea on arts of Confucius are not only to be recognized as the correspondence of behaviour and letter or morality first and letter socond but also to be recognized as pursuing of harmony between artisticality and utility.

The purpose of this study was to comparing the speech of openbite patients with normal adults and taking the fundamental data for comparing changes in post-orthognathic surgery state. Studies in speech changes of orthognathic surgery have been examined by subjective evaluation. Thus we were taken the objective results using a digital sound spectrogaph with computer-based speech analysis system. One experimental group and one control group were used for this study. They were respectively composed of six openbite patients and ten normal adults with Angles' classification Ⅰ. The results were as follows : 1. In openbite patients, Articulatory positions are formed posteriorly in pronouncing the vowel sounds. 2. Low articularoty sounds were shown in tone color(bandsidths of the first, second formants) of speech of openbite patients. 3. There was no forming the pronouncing constriction remarkable in fricative sound of openbite patinets. 4. There was the delay appearance of articulation reaction time to enlargement of total duration, vowedl duration in openbite patients.

The main purpose of a classification system is to provide a mental picture of the injury and also information as to treatment a prognosis. At present, Lauge-Hansen classfication has improved the results of conservative treatment, and Danis-Weber classification which was taken by the AO(ASIF) group was designed for application to operative treatment. But, both system have dificiencies, Recently, the proposed classification system by M. Tile which was based on the ankle stability was interesting. So, compared among the system for identification that these systems are synonymous or if not, one system has a distinct advantage over the other. Total 135 patients, 135 cases have been reviewed at CNUH from January, 1983 to December, 1988. The results were as follows: 1. We considered that it was very difficult to classify the ankle fractures by Lauge-Hansen system because of complexity and variable fracture patterns. But, we have been classified the fractures abut 98.5% by simplification of medial malleolar frecture patterns. 2. Danis-Weber classification was simple and easily applicated, but it was not helpful for decision of the amount of injury, treatment and prognosis. 3. The proposed M. Tile classification added to a aspect of the stability, so it was helpful for descision of the treatment methods. Also, this system classified the isolate medial malleolar freature that was not by Danis-Weber classification. 4. From the above results, we consider that by Lauge-Hansen classification, can be identify the occult ligament injuries, and by M. Tile classification, deside the treatment methods.
