Objectives : Osteonecrosis is a disease where there is the cellular death of bone components due to interruption of the blood supply. In these days, the clinical study and research about osteonecrosis are increased, however the study on osteonecrosis in oriental medical way is hardly studied yet. Thus, we report the significant effect of acupotomy and oriental medicine on osteonecrosis which occurred in femur and tibia. Methods : We observed recovery of symptoms and decrease of osteonecrosis region in femur and tibia by MRI. Results : During five times of acupotomy, pain on right side thigh in rest time and knee joint pain during walk were decresed after 1st, 2nd, and 3rd acupotomy. In MRI, we observed decrease of osteonecrosis region in femur and tibia, that made the patient could return to daily life. Conclusions : Acupotomy and Oriental medicine have an significant effect on osteonecrosis by pain relief and osteonecrosis region decrease.

Objectives: The purpose of this study is to investigate the effect of herbal medicine during the Western medicine therapy in adenomyosis. Methods: The author searched 5 electronic databases and search keywords were 'Adenomyosis' and 'Herbal Medicine'. We included randomized controlled clinical trials (RCTs) using herbal medicine therapy combined Western medicine for adenomyosis patients. Results: The author selected 12 studies. The systematic review of the 12 trials indicated that herbal medicine therapy integrated Western medicine therapy was more effective than Western medicine therapy alone. Conclusions: The herbal medicine therapy combined Western medicine for adenomyosis patients seems to improve pain relief and improvement of illness from this research. However, this result should be taken cautiously by unclear risk of bias. More clinical research will be needed to standardize the results of this study through herbal medicine.

A heat-treatment method of pre-annealing and then flash annealing(FA) has been used to improve the soft magnetic properties of nanocrystalline $Fe_{76}CuSi_{13}B_{10}$ and $Fe_{74}CuNb_{3}Si_{12}B_{10}$ alloys. Outstanding magnetic properties of nanocrystalline $Fe_{74}CuNb_{3}Si_{12}B_{10}$ alloy were attained by flash-annealing in air after annealed at $500^{\circ}C$ for 0.5hr below the crystallization temperature. The same results were obtained for $Fe_{74}CuSi_{13}B_{10}$ alloy. The measurment of relief of stress and X-ray diffraction were used to analyze the effect of flashannealing.

Purpose: The purpose of this study was to verify the effect of aromatherapy massage on constipation in the elderly. Method: This study for 10 day, employed a randomized control group pretest-posttest design. The experimental group received abdominal massage using essential oils with Rosemary, Lemon, and Peppermint, and the control group received a placebo massage. To evaluate the effect of aromatherapy, the degree of constipation was measured using the CAS (constipation assessment scale) and the number of bowel movements per week. Data was analyzed by repeated measures of ANOVA using the SPSS program. Result: The score of CAS of the experimental group was significantly lower than that of the control group. In addition the average number of bowel movements in the experimental group was higher than that of the control group. The effect of aromatherapy lasted 2 weeks after treatment, while the placebo effect lasted 7~10 days after treatment. Conclusion: The finding of this study showed that aromatherapy helps relieve constipation in the elderly.

This study was performed to determine the optimal doses of alfentanil or remifentanil (effect-site concentrations) required to prevent pain and other suffering after abdominal general surgery in ICU patients. A total of 52 general abdominal surgical patients (ASA IIIII) requiring artificial ventilatory care in the ICU were provided with either alfentanil (24 patients) or remifentanil (28 patients) through target controlled infusion (TCI). Alfentanil and remifentanil concentrations were titrated up and down until the pain score became less than 3 (VAS; Visual Analogue Score < 3). The effect-site concentrations (ng/ml) of alfentanil or remifentanil required to adequately control postoperative pain in the ICU were 64 +/- 12 and 1.9 +/- 0.5 for intubation with artificial ventilation, 57 +/- 9 and 1.7 +/- 0.7 for intubation with spontaneous ventilation, and 41 +/- 10 and 1.2 +/- 0.5 after extubation, respectively. Pain scores and the corresponding opioid concentrations were independent from respiratory condition. The three effect-site concentrations of alfentanil and remifentanil obtained from this clinical trial using the TCI technique can be a guideline in the administration of the same opioids to relieve the discomfort of ICU patients who have undergone abdominal general surgery.

This study was carried out to investigate the effect of deformation induced martensite on the damping capacity of Fe-26Mn-4Co-2Al damping alloy. ${\alpha}^{\prime}$ and ${\varepsilon}$-martensite were formed by cold working, and; deformation induced martensite was formed with according to the specific direction and the surface relief. With an increasing degree of cold rolling, the volume fraction of ${\alpha}^{\prime}$-martensite increased rapidly, while the volume fraction of ${\varepsilon}$-martensite decreased after rising to a maximum value at a specific level of cold rolling. Damping capacity was increased, and then decreased with an increasing of the degree of cold rolling. Damping capacity was influenced greatly by the volume fraction of ${\varepsilon}$-martensite formed by cold working, but the effect of the volume fraction of ${\alpha}^{\prime}$-martensite have a actually on effect on the damping capacity.

Nickel titanium shape memory alloys (NiTi) have been investigated for applications in the biomedical industry. However, little is known about the influences of surface modifications on the propertise of these alloys. The effect of electropolishing and heat treatments was found to exhibit significant surface roughness. Change of phase was B2, r-phase and B19' by heat treatments. In this study, effect of the electropolishing conditions on surface roughness is investigated in Ni-Ti alloys (Nitinol). Variation in phases with heat treatment temperature is investigated for a Ni-Ti alloy by X-ray diffraction and DSC. Characteristic of the microstructure have been observed by SEM. Surface roughness have been measured by AFM. The results clearly show that significant different in surface property to heat treated at $500^{\circ}C$ (R-phase). $TiO_2$ phases preciritated all of the specimens. It is not good effect of surface roughness because made to surface relief. The surface roughness appears to be important in the property of Ni-Ti alloys for biomedical applications.
