The purpose of this study is to examine factors that affect the bone mineral density of pre-menopause women by using the dual energy x-ray absorptionmetry, ultimately contributing to preventing women's osteoporosis that tends to be aggravated since menopause.Out of the subjects, 20.2% were suffering osteopenia. Age was found most important in estimating the level of bone mineral density. Meanwhile, the older women were, the significantly lower their bone mineral density was. It was found that taking exercise has a more positive effect on boss mineral density than not taking. Exercising in a suitable amount was helping women keep their bone mineral density better. Preferring meat to vegetarian diets were significantly affecting women's bone mineral density. Meanwhile, it was found that the shorter menstrual cycle is, the significantly lower bone mineral density is. A multi=regression analysis of bone mineral density and its related factors showed that the older women were, the significantly lower their bone

The purpose of this study was to investigate factors of perception by inpatients of the Primary Health Care institutions about exposure to radioactivity at the time of radioactive examination, providing basic information for making educational materials aimed to change their perception.Most of those patients, 65.5% responded that CT was a type of radioactive examination bringing highest exposure to radiosensitivity. Most of the subjects, 56.1% said that a body part most vulnerable to exposure to radiosensitivity was the genital gland at the time of radiosensitivity examination. And most of the participants, or 26.3% responded that they obtained information about radiation from TVs or newspapers.Among the surveyed patients, men were higher in scores for factors of the perception of radiation such as recognition of radiation, harmfulness of radiation, psychological state at the time of radioactive examination, prevention of exposure to radioactivity and necessity of radiation that women were, with statistically significant differences between the two groups.These findings suggest that it is urgently needed to develop an education program which helps patients better perceive exposure to radioactivity and that radiologists should be very careful to reduce the does of that exposure. If patients better perceive radiation, they would be less anxious and less exposed to radioactivity when receiving the radioactive examination.

This study is a research based on the non-equivalent control group pretest-posttest design whose purpose is to examine the effects of music therapy on the anxiety of patients who take the magnetic resonance imaging(MRI) test and their feeling of discomfort during the test."The first hypothesis that the experimental group who receive music therapy will be lower in score for anxiety during the MRI test than the control group who do not was supported because after the therapy, the experimental group was found significantly decreased in that score in comparison to the control group. "The second hypothesis that the experimental group who receive music therapy will be fewer in vital signs after the MRI test than the control group who do not" was rejected in terms of both systolic and diastolic blood pressure. But the same hypothesis was partially supported because the two groups showed a significant difference in pulse rate after the test. "The third hypothesis that the experimental group who receive music therapy will be less in the feeling of subjective discomfort during the MRI test than the control group who do not" was verified to find that the two groups were significantly different from each other in the feeling. Specifically, there was a significant difference between the two groups in only one sub-area of that feeling, that is, tension.These findings suggest that music therapy could be an alternative method which can effectively reduce the state anxiety of patients during the magnetic resonace imaging(MRI) test.■ keyword :|Music Theraphy|Anxiety|Magnetic Resonance Imaging|
