최근 서해안을 중심으로 한 한반도 주변해역에서 하계에 해파리류가 급증하면서 연안어장 및 생태계에 심각한 영향을 미치고 있는 실정이다. 우리나라 연안에서 우점하는 물해파리(Moon jellyfish: Aurelia aurita)는 전세계적으로 분포하는 종이며, 인체에 해를 미치는 유해한 종은 아니나 멸치와 같은 소형어류의 어장에 막대한 영향을 미치고 있는 실정이다. 물해파리는 소형일 때는 동물플랑크톤 중 요각류나 소형 갑각류를 먹다가 성장하면서 소형어류를 먹는 것으로 밝혀져있다( Purcell, 1985; sullivan et al., 1994).

The Oceanic ecosystem destruction caused by Water-Bloom, Jellyfish development, and Oil contamination in nation's waters becomes serious problem. For these reasons, the oceanic conditions are observed in air and on the water using helicopters and vessels. But, employing helicopters and vessels are limitted on a budget, and weather conditions. To overcome these problems, an unattended automated monitoring system not only gather all sorts of the oceanic condition in spite of bad weather, but save labor and oil costs. For each sensor connected in network and radiodetermination, location of sensors are verified in the tidal water to improve gathering informations.

This study was aimed to investigate skin whitening effects of Nomura's jellyfish (Nemopilema nomurai) hydrolyzed extracts (NHE). The extracts were prepared through the hydrolysis of N. nomurai using commercial proteolytic enzymes such as Protamex, Alcalase, Flavourzyme and Neutrase with optimum pHs (pH 5-8) at $55^{\circ}C$. Their whitening activities were examined from the inhibition of melanin synthesis using B16-F1 cell lines. Among the examined samples, Neutrase-treated extract (N-NHE) showed the most significant inhibition effect on melanin synthesis by 89.9% at a concentration of $100{\mu}g/mL$. This sample decreased the expression of tyrosinase and TRP-1 (tyrosinase related protein-1) proteins as well. These results suggested the potential application of NHE as whitening ingredients in cosmetic preparation.

This study presents the molecular phylogenetic analysis of Korean Aurelia aurita Linnaeus collected from Yeosu in the southern waters of Korea using nuclear ITS1 region and mitochondrial COI gene sequences. The use of oligonucleotide primers F5 (forward) and R5 (reverse) targeted to ITS1 and LCO1490 (forward) and HCO2198 (reverse) targeted to COI amplified 267 bp and 643 bp fragments, respectively. The shortest genetic distance towards the ITS1 region is estimated at 0.023 when comparing Korean A. aurita to Aurelia sp. collected from California, USA. In particular, Korean and American/Swedish A. aurita were located far away in terms of genetic distance, ranging from 0.393 to 0.395. On the other hand, the genetic distance between Korean and English/Turkish/Swedish/American A. aurita regarding the mitochondrial DNA COI gene ranged from 0.201 to 0.205. However, a sister-ship with Korean and American A. aurita showed an extremely high bootstrap value (100%). The predicted secondary RNA structure of the mitochondrial DNA COI gene showed many different folding structures with a similar energy between Korean and American A. aurita. These results suggest that ITS1 and the mitochondrial DNA COI gene could be used as genetic markers for identification of the biogeographic populations.
