The purpose of this study was to classify lower body types of elementary school girls. The subjects for anthropometric study were 368 girls aged from 10 to 11. Factor analysis, cluster analysis, discriminant analysis, and analysis of variance were performed for statistical analysis of the data. Four lower body construction factors were extracted by the factor analysis of antropometric measurements. The factors extracted were lower body fatness factor, lower body height factor, lower body length from the waist to the crotch factor, and lower body configuration factor. On the basis of the cluster analysis, three different lower body types were categorized. Type 1 was short and small sized type and 42.4% of subjects belonged under this type. Type 2 was tall and fat type and 22.3% of subjects belonged under this type. Type 3 was the most similar to the average type having the largest waist-hip drop value and 35.3% of subjects belonged under this type. Discriminant analysis showed 7 discriminant factors that can classify the children's lower body type were Rohrer's index, height, fibulae length, waist girth, ilio cristale girth, trochanter girth, and weight.

We investigated the structural geometry of thirty-eight Korean femurs. The purpose of this study is to identify major geometrical differences between Korean femurs and others that we believe belong to Caucasians so that we would be able to get insights into the femoral component design that fits Asians including Koreans. We utilized computerized nomography (CT) images of femurs extracted from cadavers. The CT images were transformed into bitmap data by using a film scanner, and then analyzed by using a commercially available software called Image v.1.0 and a Macintosh loci computer. The resulting data were compared with already published data. The major results show that the geometry of the Korean femurs is significantly different from that of Caucasians: (1) the anteversion angle and the canal (tare Index are greater by the amount of approximately 8" and 0.5, respectively, (2) the shape of the isthmus cross section is more round , and (3) the distance between the lesser trochanter and the proximal border of the isthmus is shorter by about 15 mm. The results suggested that the femoral component suitable for Asians should be dif- ferent (rom the currently-used components designed and manufactured mostly by European or American companies.

Background : The purpose of this study was to investigate the effects of the kinesiologic factors of gait on symmetric load. Methods : The subjects were consisted normal 33 persons (10 males and 23 females). The kinds of weight of the bag was 0kg, 5kg and 7kg. The kinesiologic factors of gait measured by three dimensional motion analysis system and callibration marker. Callibration was ASIS, hip greater trochanter, knee lateral epicondyle on sagittal plane, ankle lateral malleolus on sagittal plane, toe 5th phalange. The changes kinesiologic factor were analyzed using one way ANOVA with SPSS 21.0 package program. Results : The weight of the bag was statistical significance on change of hip joint and knee joint(p<.05). The weight of the bag was no significance on change of ankle joint(p>.05). The right and left of the lower limbs was no significant(p>.05). Conclusion : This research provides weight of bag for the gait. This study showed that symmetric load does affect kinesiologic factors of gait. This indicates that there is an interaction that plays a crucial roles in the weight of bag and kinesiologic factors of gait.

The purpose of present study was to assess the change of bone mineral density(BMD) and the influences of anthroopometric indices and body composition on BMD in Korean women in Taegu. Subjects were 242 healthy female in the range of 7-67 years old, were divided into 4 age groups in order to assess the influence o factors on BMD according to age. Body composition and BMD measurements of lumbar spine, femur(neck, ward's triangle, trochanter) and total body were performed by dual energy X-ray absorptiometry. The analysis indicated that BMD of most region was positively related to body weight, BMI in all groups 4(50-67years), and closely related to femurs than lumbar spine. This study found correlations between BMD and both total fat body mass and total lean body mass in group 1, 2, 3, and correlations between BMD and only total fat body mass and in group 4. But on regression models the most significant prediction of BMD throughout the skeleton was total lean body mass in group 1(7-16years)and 2(17-34years, and total fat body mass in group 3 and 4. It is concluded that the our data can be used to screen early women of low bone mass. This study confirms that one of the most effective way to prevent osteoporosis and the fractures is to maximize peak bone mass in early life and to minimize bone loss through maintaining adequate weight.

The initial impact at foot strike is produced by a slider type mechanical model, which can be measured using a force platform to evaluate various shoes. The lower extremity and foot motion was filmed by a 16mm high speed movie camera and several points on the rear half of the shoe and those near the trochanter and the lateral epicondyle were digitized to provide the linear and angular positions and velocities during impact. With these observed kinematics, a slider type foot strike simulator composed of guide rail and sliding dummy is designed. The simulator system makes the artificial foot of the dummy with running shoe on it to follow the foot strike motion. The dummy has the relevant mass-spring-damper system modeled after McMahon's. The motion of the model is drived by the gravity force and the generated motion alone with the ground reaction forces are monitored by the same procedures afore mentioned producing the initial foot strike impact similar to the onto observed in human gait.

The purpose of the study was to provide good fitting of ready-to-wear pants for adult women. To pursue this purpose, the anthropometric data of Korean in 1992 (ADaM(R) 1.0) were analyze. The subjects were 1,580 women aged from 18 to 50 years. The body measurements of six age groups were compared. The results of data analysis showed that the height measurements( waist height, trochanter height, glutial height, perinneum height) of the late 40's were about 3cm shorter than those of the early 20's. The waist circumference of old subject group was 14.1cm larger than those of the young subject group. With rapid growing of waist circumference, the difference of hip and waist circumference was getting smaller with aging. The average difference between hip and waist circumferences of young adult group (18 to 24 yrs) was 24.3cm (SD 3.6cm) and the meaurement of old adult group (45 to 50 yrs) was 15.0cm (SD 5.6cm). The size of the women's pants which were manufactured by the top 50 manufacturers in Korea were compared. The difference between hip circumference and waist circumference listed on the size tag ranged from 12cm to 32cm. The body measurements of subjects and the standard size categories for pants were compared. The results showed that larger size categorise needed to be added to give better fits for older adult group.

The relationships between nutrients intake, physical activity and bone mineral density were investigated in 19 elderly men aged 71-80 years. A trained nutritionist interviewed usual dietary intake and daily activity with a questionnaire, and bone mineral density was measured at the lumbar spine and three regions of the proximal femur (femur neck, Ward's triangle and trochanter) with a Luna DP3 dual photon absorptiometry. The correlations between dietary calcium intake and bone mineral density at the lumbar spine and trochanteric region were significant at P<0.05 and P<0.01 level respectively. the significant correlations were also found between vitamin A(P<0.005), riboflavin(P<0.01), and ascorbic acid(P<0.05) intake and bone mineral density at these sites. Higher physical activity was associated with greater bone mineral density of four sites, but this was not significant. But there were significant relationships between total energy expenditure and bone mineral density of the lumbar spine(P<0.01), femur neck (P<0.05) and Ward's triangle(P<0.05). In this study the results revealed that bone mineral density of the lumbar spine and trochanteric region were associated with dietary calcium intake. And bone mineral density of the femur neck and Ward's triangle were related to physical activity but not to nutrients intake. In conclusion, dietary calcium intake seems to be a important factor for greater bone mineral density. Further evidence will be needed that physical activity protects against bone fracture and osteoporosis in the edlerly.

Two standard methods of cane length measurements were compared to find which methods really achieve the elbow flexion of 20 degrees to 30 degrees Twenty-four patients with hemiplegia who were ambulatory participated in this study. Method I : Length of the cane measured from the floor to the top of the greater trochanter. Method II : Length of the cane measured from the floor to the distal wrist crease with the arm at the side. Using an adjustable cane, each individual was fitted according to the two methods, and elbow angle was measured after each adjustment. The elbow angle according to Method I and Method II was $46.4{\pm}20$, $44.3{\pm}12.2$, respectively. No significant difference was found in the elbow angle or the cane length between the two methods. Of the 24 participants, 5(20.8%) measured according to method I and 3(12.5%) measured according to method II showed the elbow angle between 20 degrees and 30 degrees. These low predictive rates of agreement between ideal cane length and actually achieved elbow angle showed that these two methods which have conventionally been accepted as a standard to measure ideal cane length need to be revised through further research.

The purpose of this study was to determine the effect of compression clothing on the body shape of the human subjects. Thirty seven healthy females being overweighted with local adiposity on the buttocks and legs between the ages of 20's to 50's were used as the human subjects for the study. The selected subjects wore the compression clothing during 60 days by 8 hours a day. At the start(T0), after 30(T30) and after 60 days of treatment(T60), a cutaneous echography was measured on the right trochanter area of each volunteer in order to assess the thickness of the subcutaneous fatty tissue. At the start(T0), after 30(T30) and after 60 days of treatment(T60), the body weight of each volunteer was taken and the instrumental variations of skinfold measurements of the abdominal fold and inner thigh circumference of the waist, hips and thigh were conducted. The results show that the echography and weight loss of subjects were reduced to 8.34% and 2.08% after 60 days, respectively. Moreover, the skinfold of subjects was also reduced. Finally, skin elastometry of subjects increased.
