In this study, five cases of post-stroke vision disorders are presented. The patients had no distinctive change in vision disorders before Korean medical treatment, which included herbal medicine, acupuncture, and electroacupuncture. After 11 to 28 days of Korean medical treatment, the patients experienced the first improvement of vision disorders after stroke. Also, patients who received Korean medical treatment after 30 days from onset, the duration in which the most improvement of post-stroke vision disorders occurs, progressed their vision disorders by the start of Korean medical treatment. Korean medical treatment might be effective in treating vision disorders after stroke.

A 70-year-old Korean female with diplopia and left ptosis due to oculomotor nerve palsy presented to the hospital. The patient was treated with electroacupuncture, sweet bee venom pharmacopuncture, and moxibustion. She also received acupuncture and herbal medicines Siryeng-tang and Boikyangwi-tang. The change in length (mm) from the medial canthus to the lateral iris was measured to evaluate limitation of eye movement, and Numeric Rating Scale (NRS) for diplopia. Limitation of eye movement and diplopia was used to determine diplopia. The limitation of eye movement and diplopia were improved after the administration of the Korean medicines. Korean medicine may be effective in treating limitation of eye movement and diplopia due to oculomotor nerve palsy.

The purpose of this case report is to evaluate the effect of electroacupuncture on Pal-sa (EX-UE9) for unilateral motor disturbance of the hand after cerebral infarction.Methods: One patient with unilateral motor disturbance of the hand following cerebral infarction (right basal ganglion and corona radiata) was treated with acupuncture, herbal medication, and electroacupuncture on Pal-sa (EX-UE9) once daily from June 30, 2016 to July 4, 2016. We evaluated improvement using the Box and Block Test (BTT) and 10-seconds Test, including the Finger Individual Movement Test (FIMT), the Hand Pronation and Supination Test (HPST), and the Finger Tapping Test (FTT).Results: After five days of treatment, increase of FIMT and FTT scores was observed after electroacupuncture on Pal-sa (EX-UE9). However, no increase was observed in BBT or HPST scores. Conclusions:This study suggests that electroacupuncture on Pal-sa (EX-UE9) can help treat motor disturbance of the hand after cerebral infarction.

The anti-cavitation performance and damage characteristics of polyurethane coatings containing carbon nanofibers (CNF) as reinforcement were investigated using the ultrasonic vibratory method in seawater (ASTM G32-10). Two commercial anti-cavitation coatings, glass flake-reinforced vinyl esther and urethane-modified epoxy, were used for comparison. During the cavitation tests, the cumulative mean depth of erosion (CMDE) was determined, and damage development against exposure time was evaluated for each coating using optical microscopy. A significant difference was found in the performance of the four polyurethane coatings. The polyurethane coating without CNF provided the least protection against cavitation attack, suggesting the added CNF improved and reinforced the resilience of the coating against impact pressure produced by cavitation bubble collapse. Excellent cavitation resistance was also exhibited by the polyurethane coating composition when fluorine was added, an improvement that may be attributed to the synergistic effect of CNF and fluorine on the polyurethane structure.
