Background & Aims: In patients with patellofemoral pain syndrome, the presence of pain, proprioception, and neuromuscular disorders leads to posture control disorder, which causes abnormal distribution plantar pressure. The aim of the present study was to investigate the effect of twelve weeks of sensorimotor exercises on distribution plantar pressure variables and symmetry index in patients wi...
[Purpose] The aim of this study was to investigate whether gaze stabilization exercise derives sensory reweighting of vestibular for upright postural control. [Subjects and Methods] Twenty-three healthy volunteers participated in this study. The center of pressure of the total trajectory length was measured before (pre), immediately after (post), and 10 min after (post10) gaze stabilization exe...
Abandonment of agricultural land is a global issue and a waste of resources and brings a negative impact on the local economy. It is also one of the key contributing factors in certain environmental problems, such as soil erosion and carbon sequestration. In order to address such problems related to land abandonment, their spatial distribution must first be precisely identified. Hence, this stu...
The geometric configuration and mechanical properties of the integral elements of the respiratory system, as well as the modus operandi of the interacting parts in the ventilation process, comprise a hard-to-visualize system, making the mechanics of pulmonary ventilation a really confusing topic for students and a difficult task for the teacher (1, 9, 10, 13). To clarify, consolidate, or even g...
An elastomer is a polymer with the property of viscoelasticity, generally having notably low Young's modulus and high yield strain compared with other materials. Elastomers, in particular rubbers, are used in a wide variety of products ranging from rubber hoses, isolation bearings, and shock absorbers to tires. Rubber has good properties and is thermal and electrical resistant. We used carbon ...
With the increased use of condoms, contact dermatitis to rubber is being seen more often. To develop a rubber condom suitable for use by rubber sensitive people, a "hypoallergenic" condom, which is washed in ammonia to reduce the residues of rubber accelerators, has been manufactured. Fifty patients allergic to various rubber accelerators were patch tested with an ordinary condom and the new wa...
A model of the chest and lungs can be easily constructed from a bottle of water, a balloon, a syringe, a rubber stopper, glass and rubber tubing, and clamps. The model is a more exact analogue of the body than the classic apparatus of Hering in two respects: 1) the pleurae and intrapleural fluid are represented by water rather than air, and 2) the subatmospheric "intrapleural" pressure is creat...
Open structure compressor is used for the compressor of automobile air-conditioner due to the drive by engine. This means shaft seal should be necessary for sealing of oil & freon gas of compressor inside. Now, lip type seal with elastic rubber lip and PTFE lip takes the high market share instead of mechanical seal and gains popular favor. More high speed , temperature and pressure are recently...
