Ceramic femoral heads in the total hip replacement have been developed to reduce the polyethylene liner wear, Alumina and zirconia (3Y-TZP) having the excellent tribological properties are coupled against acetabular cups of polyethylene and are used in clinical application worldwide. However, alumina has a risk of catastrophic failure, and zirconia has the low temperature degradation in spite of enhanced fracture toughness. Recently, novel zirconia/alumina composite is very attractive due to the low temperature degradation (LTD)-free character and high fracture toughness. In the present study, we focus on the wear of ceramic on ceramic, which are able to be used as femoral heads and acetabular cups. Therefore, LTD-free zirconia/alumina composites with three compositions are made in a form of disk and cylinder, and the wear of the composites is performed on pin-on-disk type wear tester. The wear is conducted with or without lubricant. All the composites fabricated with the different composition show the good wear resistance.

Objective : The purpose of this study is to assess treatment of children's bell's palsy based on physiological and pathological character. Methods : At the age of 0 to 15, 30 bell's palsy out-patients who visited and treated more than 3weeks at the Department of Acupuncture & Moxibustion, Dong-indang Oriental Medicine Hospital, from 07-01-2001 to 06-30-2002. They were treated with Acupuncture, Herb, Aqua-acupuncture, Physical therapy and measured by HBGS(House-Brackmann Grading System) and DEFS(Detailed of Facial Symmetry of Phillsbury and Fisch) at visit and 3 weeks after. Result and Conclusion : Children's bell's palsy is mostly caused by recent upper respiratory infection and developed most frequently on March, September, seasonally in Spring, Autumn. A group of children's bell's palsy was marked much higher than a group of adult's bell's palsy conducted by Kim's report with oriental medicine in treatment outcome. But we discovered that there was not the signifcant difference between two groups.

Purpose: The purpose of this study was to examine the puncture incidence of surgical gloves in an operational setting. Methods: The 277 surgical gloves were used collecting at one general hospital located in Seoul from February 1, 2011 to April 3. The data were analyzed by $x^2$ test, Fisher's exact test, and multiple logistic regression. Results: In the dental and orthopedic department, the puncture incidence were significantly higher than others. The time of wearing gloves demonstrated significant difference: The group 181-240 minutes had a significantly higher than those with under 90, 91-180, or over 240 minutes. The influencing factors were as follows. Compared to that of the 2nd assistants, the puncture incidence rates of the surgeons were 9.91 times, scrub nurses were 8.39 times higher respectively. The participants in work experience under 1 year showed a 4.58 times higher than those with over 7 years. In addition, compared to the puncture incidence rate of neurosurgery department, the 17.41 times in cardio-thoracic surgery, 13.89 times in dental surgery, 4.93 times in gynecology, and 4.97 times in orthopedics higher respectively. Conclusion: There is a need for training operational room personnels to occasionally exchange the gloves even during the procedure and to use double surgical gloves.

Generally, Hwabyung is more commen in older women, in low educational group. Many psychiatrists explain it as the illness originated from a series of psychological stresses. And they think that Hwabyung patients have somatization disorder, anxiety disorder, and, major depression. But, many of oriental medical doctors explain it as symptoms having the character of fire. In order to investigate the clinical aspects of Hwabyung, this study was carried out in department of oriental neuropsychiatry at Kyung Hee Medical Center. The subject was 34 year old female who was an inpatient in K.M.C from Aug. 14 Aug 26, 1996.The results of the study showed that familial problem and long-termed(about 10 years) stressed situation drove her to Hwabyung. This seems to be related to Korean traditional culture. That is, Korean women were exposured to familial problem(related to mother-in-law, and, her husband), and, poverty, etc. But they had to be patient of this situation. Nowadays, though this situation is rather improved, Hwabyung remains a problem with us, because many people still suffer from Hwabyung.

Ceramic femoral heads in the total hip replacement have been developed to reduce the polyethylene liner wear. Alumina and zirconia (3Y-TZP) are using in clinical application worldwide and there are many good test reports. However, alumina has a risk of catastrophic failure, and zirconia has the low temperature degradation in spite of enhanced fracture toughness. Recently, novel zirconia/alumina composite having low temperature degradation-free character and high fracture tough . was developed and it leads the lower wear 3f polyethylene than alumina and zirconia. In the present study, in order to optimise the microstructure of low temperature degradation (LTD)-free zirconia/alumina composite for the best wear resistance of polyethylene, various compositions of (LTD)-free zirconia/alumina composites were fabricated, and the sliding wear of UHMWPE against these novel composites were examined and compared with that against alumina and zirconia ceramics used for total hip joint heads.
