Comparison between Ankle Stretching and Self Massage for Plantar Fascia Treatments on Male and Female Posture Balance

When performing physical activity and sports, men and women are at risk of the plantar fascia that could decrease foot functions when walking, running, and jumping. Thus it requires accurate prediction results in handling it. This study aimed to determine whether clinical findings can help plantar fascia flexibility treatments and managements through ankle stretching and self-massage interventions on posture balance based on gender. This study used a quasi-experimental design with a 2x2 factorial design for male and female categories. The population of this study was 300 students, while the samples were 40 students aged 19-26 years, consisting of 20 males and 20 females. The sampling technique used stratified random sampling. Furthermore, the ankle dorsiflexion intervention was performed by stretching the ankle to overcome plantar stiffness. For self-massage, the golf ball roll relaxation gave a relaxing effect on plantar pressure. The ankle dorsiflexion and golf ball roll relaxation were performed for 45 seconds. The data collection instrument of this study was a standing stork test as a measurement reference. Data analysis used two-way ANOVA statistical test with the help of SPSS application. The results showed that the significance value of comparing ankle stretching and self-massage technique effects for plantar fascia on the posture balance based on gender was (p0.05). The significance value of posture balance in terms of gender was (p) = 0.417. Meanwhile, the difference between ankle stretching and self-massage interaction based on gender was (p) = 0.000. This study indicates that these findings can assist the treatment and management of plantar fascia flexibility through ankle stretching and self-massage interventions to balance the posture in terms of gender. Treatment for plantar fascia flexibility is more effective with ankle stretching.

CFD Analysis of Golf Ball with Various Turbulence Models.

In this research work we investigate the performance of golf ball with 256 circular arc dimples on golf ball. The turbulence characteristics and flow pattern over golf with various velocities investigated by computational fluid dynamics in suitable turbulence model, in addition that the distance covered by a ball and rotational motion characteristics also investigated with same turbulence model

Strengthening the PSO algorithm with a new technique inspired by the golf game and solving the complex engineering problem

This study has been inspired by golf ball movements during the game to improve particle swarm optimization. Because, all movements from the first to the last move of the golf ball are the moves made by the player to win the game. Winning this game is also a result of successful implementation of the desired moves. Therefore, the movements of the golf ball are also an optimization, and this has a meaning in the scientific world. In this sense, the movements of the particles in the PSO algorithm have been associated with the movements of the golf ball in the game. Thus, the velocities of the particles have converted to parabolically descending structure as they approach the target. Based on this feature, this meta-heuristic technique is called RDV (random descending velocity) IW PSO. In this way, the result obtained is improved thousands of times with very small movements. For the application of the proposed new technique, the inverse kinematics calculation of the 7-joint robot arm has been performed and the obtained results have been compared with the traditional PSO, some IW techniques, artificial bee colony, firefly algorithm and quantum PSO.
