This study measured cardiovascular capacity, body composition, physical fitness with 191 middle-aged women between 30 and 59, living in G metropolitan city who have no abnormality as a result of physical examination with a view to health and strength factors by age and model of converting such factors into health age measures and obtained the following conclusions. 1. In VC comparison by age, there were statistically significant differences between groups and in comparison of SBP blood pressure. There were statistically significant differences in body fat% and abdominal fat% as a result of comparing body composition by age. 2. In comparison of physical fitness by age, there were statistically significant differences in grip strength, sit-up, side step, reaction time, trunk extension, sargent jump, close eyes foot balance. Vo2max, and subjects in their thirties showed higher scores in physical fitness measurement and the older they are, the lower their strength.

고습도 또는 결로시 내수성을 지니는 저항형 습도센서를 제조하기 위하여 vinylbenzyl tributyl phosphonium chloride를 포함하는 4원 공중합체를 합성하여 저습도와 고습도 범위에서 측정이 가능한 습도센서용 감습막을 제작하였다. 1,5-dibrompentane과 4차 염화 가교 반응을 통하여 최종 저항형 습도 센서를 제작하였다. 감습막은 알루미나 기판에 한 쌍의 금 paste가 인쇄된 전극을 사용하였으며, 감습막은 다양한 비율의 vinylbenzyl tributyl phosphonium chloride, 2-(dimethylamino)ethyl methacrylate, 2-ethylhexyl acrylate, 그리고 [2-(methacryloyloxy)ethyl]trimethyl ammonium chloride등을 이용하여 제조하였다. 감습막은 micro-syringe를 이용하여 도포하였으며 건조 oven에서 50 ℃에서 6 시간 동안 가교반응을 진행하였다. 습도센서의 임피던스 특성은 2-(dimethylamino)ethyl methacrylate 또는 [2-(methacryloyloxy)ethyl]trimethyl ammonium chloride의 함량이 증가할수록 감소하였다. vinylbenzyl tributyl phosphonium chloride / 2-(dimethylamino)ethyl methacrylate / 2-ethylhexyl acrylate / [2-(methacryloyloxy)ethyl]trimethyl ammonium chloride의 조성비가 4/4/1/1인 공중합체의 경우 30∼90%RH 범위에서 2.64 MΩ ∼ 3.11MΩ 의 임피던스 특성을 보였으며 우수한 직선성과 낮은 히스테리시스 나타내었다.

The purpose of this study was to investigate the effect of exercise to mentally retarded women's bone mineral density. Subjects were divided into three groups: Group A(age:27.9yr, n=8)-This group was mentally retarded exercise women, who had been doing regularly exercise for over three years. Group B(age:28.8yr, n=8)-This group was mentally retarded non exercise women, who hadn't been doing it as usual. Group C(age:29.0yr, n=8) This group was normal women, who hadn't been doing it as usual. This study analysed and compared the bone mineral density between these three groups. The results were summarized as follow. 1.The BMI of group A(Mentally retarded exercise group) was 22.8±3.28 kg/m2, group B(mentally retarded non exercise group) was 22.6±5.6 kg/m2, and Group C(normal group)was 22.0±2.2 kg/m2. There were no significant differences in BMI between three groups. 2.There were significant difference in grip strength and back strength between three groups(p〈.001). The grip strength of group A was 16.9±6.5 kg, group B was 12.2±4.0 kg, and group C was 31.8±2.1 kg. The back strength of group A was 36.9±16.1 kg, group B was 34.2±8.4 kg, and group C was 96.9±32.7. 3.These were significant difference bone mineral density of lumbar between these groups. Group A was 0.1±0.08 g/cm2, Group B was 0.888±0.10 g/cm2, and group C was 1.05±0.04 g/cm2(p〈.01). 4.These were very significant difference bone mineral density of femur between these groups. Group A was 0.91±0.09g/cm2, group B was 0.74±0.08 g/cm2, and group C was 0.97±0.14 g/cm2(p〈.0001). 5.These were very significant difference bone mineral density of Forearm between these groups. Group A was 0.6±0.02 g/cm2, group B was 0.56±0.03 g/cm2, and group C was 0.63±0.02 g/cm2(p〈.0001). 6.Group A were correlations between bone mineral density of femur(neck) and BMI, weight(p〈.05). 7.Group B were correlations between bone mineral density of forearm(MID, total) and age(p〈.05). 8.Group C were correlations between bone mineral density of lumbar(L1) and age, BMI, back strength(L4).

The purpose of this study was to explore the effect of informational intervention on coping of mother's stress in unplanned childhood hospitalization. Thirty four mothers of the hospitalized children, 24 months to 60 months old, were randomly assigned to experimental and control group. Child behavioral information and parental role information was given to experimental group by booklet and cassette tape. The state-trait anxiety was measured within 12 to 24 hours following hospitalization, the state anxiety was measured during from 24 hours to 48 hours, and the parent participation with care of children, and the parent support during invasive procedures was measured during 48 hours to 72 hours after hospitalization. The data was collected from May, 1997 to October, 1998 at B hospital in Seoul. Data was analyzed with X²-test, non paired t-test, ANCOVA test and Wilcoxon test using SAS program. Results were obtained as follows: 1. There were no difference in the state anxiety during the period of hospitalization and after discharging from hospital between experimental and control group. 2. Experimental group showed significantly higher scores on the parent participation with care of children than control group(P=0.03). 3. The parent support during invasive procedures of experimental group was significantly greater than that of control group(P=0.0167). The results suggest that information intervention regarding child behavioral information and parental role information may enhance both the parent participation with care of children and the parent support during invasive procedures.

This study was undertaken to determine (1) the usefulness of chromium intensifier to improve the dignostic quality of light radiograph; (2) the effect of chromium intensifier on density, contrast;and (3) the effect of various chemical concentrations on density. the following results obtained : 1. CHROMIUM INTENSIFIER is useful for intensifying and improving the diagnostic quality of a light dental radiograph. 2. The degree of intensification can be controlled by varying bleaching time, repeating the processing, varying the proportions of the potassium bicarbonate and hydrochloric acid solutions. 3. The image produced is black and permanent. 4. The intensifier increases density and contrast.
