Objectives : Osteoporosis is the most common metabolic disease of the bone, and one of the most important public health problems around the world. Obesity rate gradually increases as women grow older. The purpose of the study was to investigate the changes between bond mineral density(BMD) and body mass index(BMI) according to sex and age. Methods : We measured the bone mineral density(BMD) of lumber spine(L2-L4) and femoral neck in 10000 normal adult, using dual energy X-ray absorptiometry (DEXA; DPX-alpha). and also measured the body mass index(BMI) in 9810 normal adult. then we analysed the changes of BMD and BMI according to sex and age. Results : 1. As getting older, male's T-score of lumbar spine(L2-L4) was slowly decreased. On the other hand, female's T-score of lumbar spine was sharply dropped after 46 years old. 2. As getting older, male's T-score of femoral was slowly decreased. On the other hand, female's T-score of femoral was sharply dropped after 49 years old. 3. Irrespective of age, male's BMI keep up the extent within a definite period of numerical value. As getting older, female's BMI continued its upward trend. Conclusions : Much more attention should be needed for female patient suffering from osteoporosis and obesity than male.

Purpose: The purpose of this study is to evaluate the synergic efficacy of oriental herb medicine for osteoporosis patients by examining whether there is any change in BMD. Osteoporosis patients are classified into a group having taken Fosamax and the other group having taken Fasamax and Samgieumgamibang in this study. Methods: Mean BMD and T-score are measured in all patients before and 3 months after treatment. Results: 1. The group having taken Fosamax showed no statistically significant mean BMD change before and after treatment. 2. The group having taken Fosamax showed no statistically significant T-score change before and after treatment. 3. The group having taken both Fosamax and Samgieumgamibang showed increase in mean BMD, which does not bear statistically significant change. 4. The group having taken both Fosamax and Samgieumgamibang showed statistically significant T-score change before and after treatment(p<0.05). Conclusions: After treatment, BMD in patients having taken Fosamx did not change significantly, but in patients having taken both Fosamax and Samgieumgamibang increased, which proves the efficacy of oriental herb medicine for osteoporosis patients.

The relationship between copper and mercury contents in the scalp hair and chronic schizophrenia was investigated. The samples of scalp hair were collected from 80 male chronic schizophrenic patients at the age from 20 to 29, who were hospitalized in the National Psychiatric Hospital in Seoul. As the control group, 69 males were collected from general population. Hair samples were taken from the napes and the Minnesota Multiple Personality Inventory (MMPI) was performed also. The copper and mercury contents were determined by an atomic absorption spectrophotometer. Significantly higher T-score of MMPI was seen in patients group for Hypochondriasis Scale (Hs), Depression Scale (D), Psychopathic Deviate Scale (Pd), Paranoia Scale (Pa), Psychasthenia Scale (Pt), Schizophrenia Scale (Sc) subscales than control group, and the frequency distribution by T-score was also significantly different between the patient and the control group for above scales. The content of copper in the hair of patient group was significantly lower than the control group. In the case of mercury, the mean value of patient group was significantly higher than control group. Between the value of copper and mercury, statistically significant negative correlation (r=-0.25) was found. When grouped by the T-score of MMPI, there was no difference of copper contents between T-score subgroup at all MMPI scale. But the mercury contents showed significant difference between T-score subgroup at Pt, Sc scale. When compared between the group of above 70 T-score and the group of less than 70, the mercury contents of Pa, Pt, Sc scale of above 70 T-score group were significantly higher than the group of less than 70. In other scales, the mercury content of the above 70 group were higher than the group of less than 70 except Mf scale, although there were no statistscally significances. In D, Pa, Sc scales, as the T-score of MMPI increased, the contents of mercury also increased. When divided into the patient group and the control group, the copper contents of the patient groups were significantly lower than the control group at each T-score scale in most MMPI scales. In the case of mercury, the value of patient group were significantly higher than the control group in the less than 44 scale of D, in the $60{\sim}69$ scale of Pd, in the $45{\sim}59$ scale of Mf, in the $60{\sim}69$ scale of Ma, in the less than 44 of Si. These results suggest that the effects of the deficiency of copper or high intake of mecury on schizophrenia and personality may be of possible value. Thus further studies are necessary to determine whether schizophrenia and personality formation would be attributed to copper deficiency or mercury intake.

The purposes of this study are to develop 'Squat Scoring Scale' and identify relationship between squatting score and flexibility of the lower extremity muscles such as quadriceps femoris and soleus in terms of relationship between squatting and functions of lower extremity. Subjects have normal gait patterns only with or without musculoskeletal problems of lower extremities, lumbar and pelvis and gender. There are sixty subjects who participated in this study. The scoring are checked after squatting posture according to 'Squat Scoring Scale', and measured ROM of the ankle dorsiflexion and knee flexion for flexibility of the soleus and quadriceps femoris, respectively. Fourteen of sixty subjects have 10 score, seventeen subjects have 9 score, seven subjects have 8, 7 and 6 scores, three subjects have 5 score, and five subjects have 4 score. The gap between 10 to 9, 9 to 8 and 8 to 7 score in all values of angles has the statistical significance for t-test(p<.05). This information indicates that flexibility of quadriceps femoris and soleus acts as important factors in squatting.

The purpose of this study is to measure the impact of Korean speakers' English stop pronunciation on their general pronunciation proficiency. For these purposes, 20 Korean speakers read English sentences and their pronunciations were rated by native English speakers. The Korean speakers' VOT values of English stops in sentences were then measured and the relation between the VOT values and native speakers' pronunciation rating was compared. Here, the relation between (1) the proficiency score of each speaker and VOT values; and (2) the proficiency score of each sentence and VOT values were analyzed. The results show that there is a relation between the proficiency score of each sentence and VOT values of /t, b, d, g/; and there is a relation between VOT values of /t, b, d, g/ and proficiency scores of each speaker while these is a weak relation between VOT values of /p, k/ and proficiency scores of each speaker.

Objectives : The purpose of the study is to investigate Korean scaling fear (KSF)-1.1 and related factors in scaling patients. Methods : The subjects were 314 scaling patients in 7 dental clinics in Daegu from April to June, 2013. Data were analyzed for simple frequency rate, t-test and ANOVA(Sheffes's post hoc) for the identification of the differences between KSF-1.1 and variables. Multiple regression was analyzed for the impact of independent variable on the score of KSF-1.1. Results : Mean score of KSF-1.1 in 314 scaling patients was 2.60. Female patients (2.71) had a higher score than male (2.47) (p<0.01). Those who didn't get a regular dental check up(2.87) tended to have higher fear level than those who had regular checkup (2.46) (p<0.001). Those who experienced dental pain (2.90) had significantly higher score than those who had not (2.46) (p<0.001). There was a significant difference between three groups (yes 3.03, ordinary 2.79, and no 2.42) in scaling (p<0.001) and financial burden (p<0.001). Variables associated with score of KSF-1.1 were gender(${\beta}$=0.21, p<0.05), waiting time for scaling(${\beta}$=0.24, p<0.01) and financial burden (${\beta}$=0.22, p<0.02) by multiple regression analysis. Conclusions : The influencing factors of scaling were gender, financial burden, waiting time for scaling that may effect on a score of KSF-1.1.
