두통으로 내원한 8세 남아에서 2세부터 시작된 안구 마비성 편두통 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Ophthalmoplegic migraine is defined as recurrent unilateral headaches associated with extraocular muscle palsies. This disorder is more common in older children, but it may begin in infancy. Neuroimaging study should be performed to rule out conditions resulting in third nerve compression, such as intracranial aneurysm or mass lesions. Early treatment with corticosteroids could shorten the duration of the ophthalmoplegia and relieve the pain. We report a 8 year old boy who had severe headache with recurrent ipsilateral ophthalmoplegia that developed at the age of 2. The pediatrician should be aware that ophthalmoplegic migraine may occur in infancy and that early systemic steroid therapy is critical to prevent permanent sequelae.

Ocean noise may be used for monitoring wind speed and rainfall rate on the sea surface, as well as for tracking whales’ migration routes. In particular, low-frequency ocean noise has recently been of concern with relation to the behavior of marine mammals. Low-frequency ocean noise has been increasing over the past few decades due to increase of ship traffic and offshore oil industry activities. Mechanical noise such as flow noise and cable strumming noise may be induced if low-frequency ocean noise is measured by cabled traditional hydrophone in high current areas. To successfully measure low-frequency ocean noise in a shallow water environment with strong current, we developed a self-recording hydrophone. This paper describes the main configurations of the self-recording hydrophone and presents some results on measured data.
