Purpose: The study examined the effects of the proprioceptive neuromuscular facilitation pattern exercise and protein intake on balance, gait ability, and lower extremity muscular strength for sarcopenia in the elderly. Methods: A total of 30 elderly people (65~74years) with sarcopenia were recruited and randomized to Group I (n=10), Group II (n=10), and Group III (n=10). Their balance ability was measured using the functional reach test. Group I performed the proprioceptive neuromuscular facilitation pattern exercise and protein intake. Group II performed the proprioceptive neuromuscular facilitation pattern exercise. Group III performed protein intake. Their gait ability was measured using the Timed Up and Go test. Lower extremity muscular strength was measured using the Five Times Sit to Stand test. Results: As a result of comparison within groups, Group I and Group II showed a significant difference in balance, gait, and lower extremity muscular strength after the experiment (p<0.05), and Group I showed a more effectively significant difference than either Group II or Group III in balance, gait, and lower extremity muscular strength before and after the experiment (p<0.05). Conclusion: This study showed that the proprioceptive neuromuscular facilitation patterns exercise and protein intake was effective in balance, gait ability, and lower extremity muscular strength for sarcopenia in the elderly.

The purpose of this study was to investigate the changes in walking pattern of the elderly during inclined walkway with uneven surfaces and level walking. 10 young($26.3{\pm}1.3$ years, $174.3{\pm}5.3\;cm$, $69.5{\pm}9.5\;kg$) and 13 elderly($72.4{\pm}5.2$ years, $164.5{\pm}5.4\;cm$, $66.1{\pm}9.6\;kg$) male subjects were participated in the experiment. Experiment consisted of 2 walking conditions: horizontal and inclined walkway with uneven surfaces. 3D motion capturing system were used to acquire and analyze walking motion data with sampling frequency of 120 Hz. To compare differences between conditions, kinematic variables(walking speed, stance-swing ratio, hip joint angle, knee joint angle, ankle joint angle, pelvic rotation angle) were used. Results showed that there were some changes of elderly walking pattern in inclined walkway with uneven surfaces: hip joint(adduction and rotation) and pelvic movement pattern. These changes by inclination and surface may affect gait pattern of young subjects as well as elderly subjects. However, in case of elderly it revealed more unstable gait than the young. Further study is necessary to clarify changes in walking pattern for elderly by considering various gait variables including head movement and various walkway conditions.

The purpose of this study was to compare and analyze the pants pattern of the lower body of 70-85 aged women. I tried to present excellent pants pattern that is convenient and suitable for the activities of elderly women. Through this, I tried to provide basic data necessary for making elderly women 's pants. As a result of evaluating the appearance of the pants pattern according to the body type, the fit of the type 2 was evaluated as the highest in the item except the position of the front waist line. For the objective evaluation of the 3D simulation, the air gap of the pants by the body part analysis showed that there was not much difference in the air gap around the waist circumference, hip circumference, thigh circumference, and knee circumference by applying the same drawing method and body size. However, in type 2, the air gap of thigh and knee circumference parts was larger than that of type 1 and type 3. Because type 2's legs were thin but it used same size of hemline. It was thought that it is necessary to adjust the space of front and back crotch length to 1 inch (2.54 cm) instead of 1.9 cm (3/4 inch) so that the waistline position of all three types can be set up a little to cover the abdomen. This study was conducted to investigate changes in body shape of elderly women and to develop appropriate pants patterns.

The study performed a comparison analysis of market brand patterns for slim-fit dress shirts and analyzed the body surface development figure of men in their 40s using 3D body scan data and developed slim-fit dress shirt patterns suitable for middle-aged men. The sizes of slim-fit dress shirt patterns showed a slight difference depending on brand. The overlap map of slim-fit dress shirt patterns for brands demonstrates how difference of one-dimensional sizes reflect on two-dimensional patterns. This map provides useful information for pattern design and allows and easy recognition of pattern size differences. A try-on system evaluation through 3D-Simulation allows a grasp of the fitness of neckline and size tolerance of under the arms in front, the silhouette of side lines, and overall fitness in front that also allows analysis of the front/back balance of a shirt in side, the size tolerance proportion in front/back, and the fitness of the arm-hole line. Thus, we obtained try-on results that were equivalent to wearing actual clothing. According to the drafting size suggested in the developed final pattern, the total width was 'C/2+5.5cm', and the front was set at 1cm bigger in the size difference of the front and back. The width of the front neck and the back neck was set identically at 'C/12', while the width of the front neck was set to 'C/12+1.5cm'. For the armhole depth, we added 'C/4+2cm', and '0.5cm and 1.5cm' for the width of the front and back to anthropometry. The results of the try-on evaluation through 3D-Simulation indicated that the fitness of the final slim-fit dress shirt pattern was superior to available slim-fit dress shirt patterns on the market and evaluated as superior to the types for middle-aged men.

Purpose: The purpose of this study was to compare the intramuscular activation of the scapular stabilizing muscles and the upper trapezius/middle serratus anterior (UT/MSA) ratios during shrug exercise and proprioceptive neuromuscular facilitation (PNF) scapular pattern exercise. Methods: The participants of this study were 13 young adult men who voluntarily consented to participate in this experiment after listening to its purpose and methods. All participants were instructed on maximal voluntary isometric contraction and scapular exercises. The intramuscular activation of the upper trapezius (UT), lower trapezius (LT), middle serratus anterior (MSA), and lower serratus anterior (LSA) muscles while performing scapular exercises in a side-lying position were measured using surface electromyography. To analyze the muscle activation and UT/MSA ratio between the two exercises, a one-way repeated ANOVA was performed. Post-hoc analyses were conducted using Tukey's multiple comparison and analysis. Hamstring flexibility for each group was measured by a passive straight leg raising test. Results: The shrug exercise showed significantly higher UT activation compared to PNF anterior elevation and posterior elevation scapular patterns. The PNF scapular anterior elevation pattern showed significantly higher serratus anterior activation than the shrug exercise. Additionally, the UT/MSA ratios were significantly lower in the PNF scapular anterior elevation pattern than in the two exercises. Conclusion: Although shrug exercise was effective for strengthening UT, the PNF scapular anterior elevation pattern may be effective for strengthening MSA and improving the UT/MSA ratio.
