The purpose of this study was to investigate the physical characteristics and instrumental activities of daily living(IADL) of the elderly (85+). The subjects were three-hundred elderly people over the age of 85, living in Kyungpook Sung-Ju area who have no problems in daily living. The survey on anthropometric measures and IADL were carried out by individual measurement and interviews using measuring devices and questionnaires. The subject group of the study was composed of 27% males and 73% females, the average age being 87 years old. Notable physical features of the subjects include considerably short statues and small physiques compared to the average Korean elder. The mean Body Mass Index(BMI) was 20.9. The average percentage of body fat in male and female was 21.7% and 29.5% respectively, and the average waist/hip ratio(WHR) was 0.9 and 0.85 respectively. The percentage of the subjects who were able to perform all the IADL was 51% in males and 25% in females. The male subjects were more capable than the females in all the IADL except for preparing meals. BMI showed positive correlations withy weight(r=699), WHR(r=0.157), body fat percentage(r=0.57), lean body mass(r=0368) and total body water(r=0.368). WHR also had positive correlation with weight(r=0.184), BMI(r=0.157), lean body mass(r=0.149) and total body water (r=0.148). Body fat percentage had a positive correlation with weight(r=0.147) and BMI(r=0.265) and total body water(r=0.265). In summary, the elderly(85+) in the Sung-Ju area had considerably smaller physiques than the average Korean elderly and showed a normal range of BMI in average. The IADL of the elderly(85+) appeared to have a positive correlation with lean body mass and total body water and a negative correlation with body fat percentage.

For the elderly, achieving a close-to-normal ambulation is important for activities of daily life. Recent researches of SE(Silver Engineering) restoring physical ability would help the elderly by developing the advanced gait assisting devices and orthoses. For the applications using the advanced technologies, the gait characteristics of the elderly must be understood. However, a few studies were performed to investigate the physiological or pathological gaits. The purpose of this study is to provide the gait analysis data and also to investigate relationships between alignment of the lower limb, foot progression angle and knee joint moments in the healthy elderly. By participating a total of 20 healthy elderly persons in this study, the following facts were found: 1) Cadence showed 114.8 steps/min, gait speed showed 1.05 m/s, time per a stride showed 1.06 sec, time per a step showed 0.53 sec, single-supporting phase was 0.41 sec, double-supporting phase was 0.24 sec, stride length was 1.04m, Step length was 0.56m; 2) The maximum knee flexion angle through swing phase showed left 46.82$^{\circ}$, right 40.19$^{\circ}$ and the maximum knee extension angle showed left -1.32$^{\circ}$, right 2.01$^{\circ}$. Knee varus showed left 26.90$^{\circ}$, right 30.93$^{\circ}$; 3) The maximum knee flexion moment showed left 0.363 Nm/kg, right 0.464 Nm/kg, The maximum knee extension moment showed left 0.389 Nm/kg, right 0.463 Nm/kg. The maximum knee adduction moment showed left 0.332 Nm/kg, right 0.379 Nm/kg. The maximum internal rotational moment showed left 0.13 Nm/kg, right 0.140 Nm/kg; 4) The subjects who had varus alignment of the lower extremity had statistically higher in knee adduction moment in mid stance phase; and 5) The subjects who had large foot progression angle had statistically lower in knee adduction moment in late stance phase.

The purposes of this study were to estimate nutritional intakes of the long-lived elderly and to obtain the data for establishing dietary guidelines that may be recommended for the general population for the sake of longevity. The subjects of the study were 300 elederly people of age over 85 years living in Kyungpook Sung-Ju area who had no problem in daily living. Four times of food consumption survey were carried out seasonally by the repeated 24-hr recall method for one year. Mean daily energy intakes and RDA percentage of energy intakes of the male and female subjects were estimated as 1222 kcal(67.9%) and 1047 kcal(65.4%) respectively. Mean daily intakes of nutrients were estimated as 38.3g for protein, 287mg for calcium, 5.8mg for iron, 314R.E. for vitamin A, 0.6mg for vitamin B1 and 0.43mg for vitamin B2 The mean RDA percentages of nutrients intake were 64.4% and 59.8% for protein in male and female, 39.8% for Ca, 48.3% for Fe, 44.9% for vitamin A, 60% for vitamin B1, and 35.8% for B2. The average PFC ratio of energy-yielding nutrients throughout the year in male and female were 15.1 : 15.2 : 69.7 and 13.8 : 13.2 : 73.0 respectively. The mean daily intakes of energy and most of nutreints were significantly high in winter season. The contribution of plant food sources to nutrient intakes were over 60% for protein and fat, 50% for calcium, and 70% for iron. Long-lived elderly people an Sung-Ju, Kyungpook showed considerably smaller physiques compared to the avergae Korean elderly, however their average BMI fell in normal range. The subjects were consuming much less energy and nutrients compared to the present Korean RDA for the elderly over age 75. The subject showed relatively good health state in spite of low intakes of energy and nutrients. Therefore it seems to be necessary to establish a set of new RDA for the elderly over age 8.5.

Objective: The purpose of this study is to develop new balance evaluation index that can discriminate fall risk factors and provide effective interventions for healthy elderly. In order to conduct this study, the balance assessment tools (TUG, mCTSIB, OLST, FRT and BBS) currently used in clinic were re-evaluated using biomechanical analysis. Method: The participants were healthy elderly people over 65 years old, n=26, age: 69.31±3.13 years; height: 154.00±4.12 cm, body weight: 56.13±6.04 kg. The variables are length of CoM-BoS, length of CoP-BoS, range of CoP, mean distance of CoP, mean frequency of CoP, root mean square of CoP, joint angle, ASM (%SL), CoP-CoM angle. Results: As a result of this study, the following items were included in the list of new balance evaluation index for the healthy elderly, showing differences in the biomechanical evaluation based on the clinical evaluation (Inclusion list: TUG, OLST, 8th assessment item of BBS (reaching forward with outstretched arm), 11th item (turning 360 degrees), 13th item (standing with one foot in front), 14th item (standing on one foot)). Conclusion: Based on the results, the new balance evaluation index for the healthy elderly determined through this study can be used to prevent the fall by evaluating the balance ability in various situations that can be experienced in the normal daily life of the healthy elderly.

Purpose: The purpose of the study is to explore the socio-psychological coping process and experiences of families before and after institutionalization by applying the Corbin and Strauss ground research method. Method: Data collection from 9 participants with elderly institutionalized dementia with approval from directors of the institute was done by in depth interviews during a seven month period from May, 2003 to December, 2003. Data analysis was done by repeated reading of the transcribed interviews, and 344 concepts and 39 subcategories were generated. Results: Family members of the dementia elderly experienced various degrees of exhaustion, physically, mentally, and socially. The degree of their exhaustion was related to the severity of the family member's symptoms, and length of the dementia. Coping strategies were effected by economic status, social support from blood related families or neighbors, depth of their relationship with elderly institutionalized dementia. They were even affected by the elderly family members institutionalization. Conclusion: After institutionalization participants felt some guilt from not assuming their responsibilities as children. On the other hand they regained privacy, freedom, security, and comfort, so that their life returned to normal. They even felt more comfort because their elderly were living in a safer environment, and received a better quality of care. Participants had better composure, so that they could even take care of neighbors in need. They hope that there is more governmental involvement in terms of subsidy and numbers of institutes. Findings of the study will be a ground for the development of a coping program for families with elderly institutionalized dementia. Further studies are recommended to explore types of family, and to develop programs for the families to help them interact with each other.

The purpose of this study is provide reference data for anthropometry and body composition and also to compare body fat estimation among skinfold thickness, BIA and NIR methods. Anthropometric measurements of height, weight, eight sites of skinfolds and six sites of circumferences were taken from 76 elderly male and 153 elderly female. Skinfold thicknesses, body composition and circumferences except waist were lowered with advancing age in elderly females and males. The degree of change with age vaired among parameters but was consistently and significantly(p<0.05) greater in elderly females than I males. Although sum of skinfold thicknesses and the amount of central and peripheral fat were significantly higher in females than that of males, the ratio of central fat to peripheral fat was significantly greater in males than in females. WHR is also significantly higher in males than that of females. This indicates that fat distribution of males tend to be centralized toward the trunk of the body than females. Estimation of body fat from skinfold thickness(male : 18.5$\pm$4.1$\%$, female : 29.7$\pm$4.0$\%$) and BIA(male : 19.5$\pm$7.3$\%$, female : 29.6$\pm$6.7$\%$) were similar but were significantly different from NIR method(male : 24.7$\pm$5.6$\%$, 34.8$\pm$4.9$\%$). Estimation of body fat by NIR measurement seemed to be more overestimated. Understanding the normal changes in body composition with increasing old age, and the ability to measure these changes and compare them with appropriate reference data are important for the health of the elderly.

This study intended to evaluate the validity of the simple nutrition screening test that had been developed with the elderly living in Cheongju as a subject. Nutrition screening score(NSS) and reference standards for nutritional and health status(nutrient intakes, mean adequacy ratio, perceive health, and serum albumin, hematocrit, and hemoglobin) were estimated by using the date obtained in 1996 from the 174 elderly living in Taejon, Statistical analysis showed significant correlations between mean adequacy ratio(MAR) and NSS(r=0.341) and also between NSS and biological indices such as albumin and hematocrit, Around 65-75% of the elderly with perceive health and low level of serum albumin, hemoglobin and hematocrit had NSS$\leq$ll. Sensitivity, specificity, and positive predictive values(PPV) were calculated from the crosstabulation of the three categories of NSS(high, moderate, and low nutritional risk) and low categories MAR(< 0.75, undernutrition;$\geq$0.75, normal) to validate the cut-off point for high or low nutritional risk by NSS. It was suggested that point l1 was appropriate as a criterion to determine high risk of undernutrition, but point 16 was better than 17 as criterion to determine low nutritional risk in the Taejon elderly. When point ll was used as a criterion of high nutritional risk, sensitivity, specificity, and PPV are 59.5, 60.5 and 82.1 respectively. When point 16 was used as a criterion of low nutritional risk, sensitivity, specificity, and PPV are 25.6, 95.4, and 64.7%, respectively. In conclusion, nutrition screening test that had been developed can be a simple, easy, and proper instrument to classify the high risk group of undernutrition. A further validation study seems to be required among other groups of individuals for the screening test to the finalized as a more valid instrument identifying Korean elderly at nutrition and health risk(Korean J Nutrition 33(8) : 864-872, 2000)
