Purpose: This study examined the demographic and lifestyle differences between women with osteopenia and those with normal bone mineral density (BMD) to identify risk factors for osteopenia. Method: Participants comprised 381 women age 40-64 years. Data were collected using surveys, BMD measures, and anthropometric parameters. Results: Prevalence of osteopenia was 29.1%; significant differences in age group, job, age at menarche, age at menopause, and body mass index were found between women with osteopenia and those with normal BMD. Logistic regression analysis indicated that advanced age, unemployment, lower body mass index, and lack of exercise in women were significantly associated with osteopenia. Conclusion: This study suggests the need for strategies to improve bone health and continuous cohort studies to identify risk factors.

The purpose of the present study was to investigate the age-related and encoding-, or retrieval- conditions-related differences in recall and to assess any possible interaction between encoding and retrieval conditions. 108 first and fifth grade children and college adults were presented a 30 item set of pictures for recall it a 2-trial study-test procedure. The data were analyzed in 3(age) x 3(encoding condition) x 3(retrieval condition) x 2(trials) mixed analyses of variance with repeated measures on the last factor. The results indicated the age-related differences in recall and encoding conditions-related differences in recall in the fifth-graders and college adults. Also, the first and fifth grade children's recall was influenced by retrieval conditions. The fifth graders' recall was a function of the interaction of encoding and retrieval conditions.

The objective of this study is to offer some standards for the classification of Sasang Constitutions according to age groups through analyzing the characteristics of their body shape and comparing with their frontal silhouettes. The subject of this study were 192 female and 167 male patients who aged from 17 to 64 in Pusan. They were treated with Sasang Constitutional medicine. 5 Heights, 7 widths of their body were measured with modified IBS-2000. Collected 12 anthropometric data was analyzed by T-test and ANOVA. Width is more suitable than height in estimating Sasang Constitutions regardless of gender differences. W2_1, W2_2, W2_4, W2_5, W2_51 are suitable to estimate Sasang Constitutions regardless of gender differences and age groups. in case of female, H45 in 33${\sim}$64 age group is suitable to estimate Sasang Constitutions. In case of male, H12, W2_1 in 17${\sim}$32 age group and H01, W2_0, H23 in 33${\sim}$64 age group are suitable to estimate Sasang Constitutions. All Sasang Constitutions with the exception of Taeyangin female have to consider age groups, when we estimate Sasang Constitutions. From the above results, we have to consider not only gender differences but also age groups to classify Sasang Constitutions from body shape point of view.

The values of blood composition were analyzed by age, season, and sex from Chejuhorse in Korea. The results obtained were summarized as follow; 1. The values of white blood cell(WBC), packed cell volume(PCV), mean corpuscular volume (MCV), and mean corpuscular hemoglobin concentration(MCHC) were significantly different between age. The WBC value was decreased with the progress of age and the PCV value was lower in the early age of 1,2 to 3 years than in the higher age of 4 to 5, and over 6 years. 2. The mean value of MCV was increased with the progress of age but the adverse was true in MCHC. 3. In the case of seasons, the values of red blood cell(RBC), WBC, hemoglobin(Hb) PCV, MCV, mean corpuscular hemoglobin(MCH), MCHC, globulin(Glo), albumin/globulin(A/G) ratio, inorganic phosphorus(Pi), cholesterol(Chol), and chlorine(Cl) showed significant differences. The number of RBC was not varied from winter to summer but decreased in autumn. The number of WBC was high in summer and autumn, but low in winter and spring. 4. The values of MCV were high in autumn and winter, but low in spring and summer. 5. The values of MCH and MCHC were similar in spring and summer, but strikingly increased in autumn. 6. The values of Glo and A/G ratio were negatively correlated with the season; The value of A/G ratio was lowest in summer but no differences were observed in spring, autumn and winter. On the other hand, the value of Glo was highest in summer but no differences were observed in spring, autumn, and winter. 7. The values of Pi, Chol, and CI were high in summer and winter, but low in spring and autumn. 8. The values of RBC, MCV, and MCH were significantly different between sex. The value of the RBC count in male was higer than the female, but the adverse is true in MCV, and MCH.

The purpose of this study is to observe the age differences in safety perception among babyboomer, pre-elderly, and the elderly and to seek for countermeasures to overcome the risk. The data used for this study were from the 2008 Social Survey conducted by Administration on Statistics, Korea. The data were divided into three different age groups such as babyboomer, pre-elderly, and the elderly. Results showed that overall safety level of the society, safety perception of others and oneself, current social safety level compared to 10 years ago, social safety level after 10years, awareness of safety among different social fields, and the rank among the list of factors that lead to social insecurity appeared to differ according to the three different age groups. The awareness of safety for the elderly group was not higher than babyboomer and pre-elderly groups. Age differences in safety perception reflected the times and experiences the same age cohort went through. Countermeasures for security should be developed by considering the characteristics of the generations and different age groups.

The widths of upper arch increased by age both in males and females except the region of second deciduous molars. 2. The widths of lower arch increased by age significantly both in males and females. 3. The lengths of dental arches increased by age both in males and females at anterior portion. ; did not increase at Posterior portion. 4. The upper widths of males were wider than those of females at age 9, but no significant difference were present at age 7 and 8. 5. The differences of the lower widths between males and females were not present except the region of the second deciduous molars (E-E) at age 7. 6. There were few differences between the lengths of males and females except the posterior lengthes at age 7. 7. The widths and lengths of upper arches were difinitely wider and longer than lower arches.
