An orthopedic device for stabilizing the thumb, i. The device comprises a base adapted for stationary mounting relative to a fluid flow generated by the ocean waves. Specifically, by attaching marks such as rectangles, characters, or lines, to an electron microscope image with software, quick navigation is performed with required minimum information. The first configuration substantially prevents fluid communication through the passage, and the second configuration permits fluid communication through the passage. According to this exemplary embodiment, the structure further comprises a UV radiation blocking layer situated directly over the interlayer dielectric layer, where the UV radiation blocking layer is selected from the group consisting of silicon-rich oxide and silicon-rich nitride. The light guide includes an input surface that receives the subject image and is provided at a front surface side; a first light reflective surface that is opposed to the input surface and is provided at a back surface side; and a second light reflective surface that extends in a thickness direction of the light guide.
