Cutaneous injuries stung by jellyfish are not uncommon in human exposed to marine environments. Most of the cases occur to scuba divers, fishermen, and travelers swimming at the beach. The symptoms vary from mild dermatosis to fatal systemic reaction. Some group of jellyfish like Atlantic Portuguese man-of-war (Physalia physalis) provokes acute severe skin injuries with systemic symptoms of nausea, bradycardia, and rarely anaphylaxis. But it is unusual case that allergic dermatitis caused by Scyphistoma which is polyp stage of jellyfish (Aurelia aurita) happened to zoo keepers working at indoor dolphin pool. This case report is about dermatosis with symptoms such as painful, irritant, itching, and erupted skin lesions on the neck and face of zoo keepers working at dolphinarium in Seoul zoo, Korea.

This paper was described on the characteristics of bottlenose dolphin (Tursiops truncatus) whistle to develop a warning and attracting acoustic system which can be made friends woith environment and minimized to the fishing pollution from Cetaceans. The experiment for the acoustics of bottlenose dolphin whistle was carried out in dolphin performance hall at Seoul Grand Park during 18th~19th April, 2002. The frequency and the spectrum level of whistle a same pool were revealed 6~10KHz and 85㏈ but those revealed two harmonic waves a 6.7KHz and 21.3KHz for the frequency and 110㏈ and 94㏈ for the spectrum level, respectively, when a dolphin isolated from others. The range of frequency change of whistle was 3.86KHz and continuous time was 0.08 sec. The range of frequency change 10.20 KHz higher as 14.06 KHz and continuous time was 0.11sec longer as 0.19sec when a dolphin isolated from others. By the Mann-Whitney test for the result, there was a significant difference for the range of frequency change and continuous time between normal condition and when a dolphin was isolated from others. The pattern of whistle at the dolphin performance hall was five types and the frequency was getting increased slowly in the range of 5~10KHz at normal condition but there were pattern change of 5~20KHz at the isolated condition. Therefore it is thought that these experiments would be valuable for the development of acoustic system.
