A large number of divers that are engaged in a diving apparatus fishery (DAF) have been experienced a decompression sickness. This study has two purposes. One is measurement of the diving patterns and respiration rate. The other one is to research the institutional improvement plan of the DAF. In the experiments, the diving depth, the diving time, the total ascent time and the ascent rate were about 12.4 m, 22 min, 28 s and 28.1 m/min, respectively, in Tongyeong. In the case of Geoje the diving depth, the diving time, the total ascent time and the ascent rate were about 20 m, 64 min, 17 min and 1.3 m/min, respectively. In a questionnaire survey, the diving depth was 20~29 m (56.4%) in Tongyeong and Geoje, the diving time was 50~59 min (42.9%) in Tongyeong and 70~79 min (35%) in Geoje and all of the divers experienced decompression sickness. In the investigation related to a institutional issue, both of the diving apparatus fisheries had adopted the share system. And the laws and the system for the safety of the divers were not enough in Korea. This study suggests that the license and the diving time for diver of the DAF are needed and diver protection for decompression sickness is needed in the law. And the wage payments should change from full sharing to partial sharing included a regular pay to enhance the safety of the divers.

Korean traditional mask play was done at outdoor to let spectators join the play and take mask at performance and to have disadvantage of poor transfer of dialog to the spectators. Performers transferred dialog directly and/or indirectly by using visual costume, and Tongyeong Ogwangdae with many dialogue expressions concerning the costume made use of proper intention to help spectators understand. In this study, the author watched performance of Tongyeong Ogwangdae to collect and investigate not only image material but also photograph material and to classify intention of the costume into three: First, contents of the dialog were intended to make shape. The costumes of Hongbaek Yangban, Meoktal Yangban and Jorijung of the 2nd section gave spectators contents of the play, and the costume of Halmi Yangban of Nochangtal of the 4th section described dialog of Halmi. Second, dialog had connotative metaphor. The costume of Yeongno of Yeongnotal of the 3rd section symbolized an unfinished dragon, while that of Halmi of Nongchangtal of the 4th section did sacred of Halmi. And, Nongchagtal Ai's costume of the 4th section prayed for value of Ai, richness of the life and fecundity. Third, conflict between characters was intended by indirect media. The costume of Maltukee of metaphor mask of the 2nd section became base of the assertion supporting that Maltukee had better birth history than Yangban had, and the costume of Yeongnoyangban of Yeongnotal of the 3rd section produced conflict at disclosure of identity.

본 연구는 해양 식물플랑크톤의 개체수 및 생체량과 chlorophyll $a$ 농도간의 연관성을 파악하기 위하여 2000년부터 2010년까지 인천, 통영, 울산 해역의 34개 정점에서 1160개 시료를 분석하였다. 연구결과 개체수와 chlorophyll $a$ 농도가 생체량과 chlorophyll $a$ 농도보다 높은 상관성을 보여 우리나라 연안해역에서는 1차 생산의 분석에 있어서 개체수 지표를 사용하는 것이 생체량을 사용하는 것보다 더 효율적일 것으로 판단된다. 그러나 좀 더 자세한 결과를 도출하기 위해서는 시기별로 보다 많고, 정확한 생체량 데이터를 확보하고, 시기별 chlorophyll 함량 자료의 축적과 함께 국내 연안에서 적용 가능한 모델 구축이 반드시 필요하다.

The diet composition of Takifugu niphobles was studied with 587 specimens collected in the eelgrass bed of Jangpyeong-ri, Tongyeong, Korea, using a seine net, monthly from May 2016 to April 2017. The standard length (SL) of the specimens ranged from 0.7 to 9.0 cm. The stomach contents analysis indicated that T. niphobles consumed mainly amphipods (%IRI: 91.0 %). In addition, T. niphobles fed on small quantities of copepods, polychaetes, insects, bivalves and crabs. T. niphobles consumed mainly amphipods over all size class. Smaller individuals (less than 4 cm SL) fed mainly on amphipods and copepods. The proportion of copepods decreased, as body size increased, whereas the consumption of polychaetes increased gradually. The seasonal variation in the diet composition of T. niphobles was significant. Amphipods were most common prey in all seasons. Copepods decreased from summer to spring gradually whereas the consumption of polychaetes increased in autumn.

점등 효과에 따른 동물플랑크톤 군집동태의 변화를 관찰하기 위하여 통영 바다목장 해역내 한국해양연구원 가두리 설치 지역에서 2004년 7월부터 2004년 8월까지 채집을 실시하였다. 점등 효과를 알아보기 위한 시료 채집은 야간에 점등구간에서 또한 자연상태의 동물플랑크톤 군집과 비교분석을 위하여 같은 시간에 인접 지역에서 점등에 영향을 받지 않는 장소를 선정하여 점등 시료와 동일한 방법으로 채집하여 비교 분석하였다. 조사기간 중 출현한 동물플랑크톤은 종 수준까지 동정한 21종을 포함하여 총 43개 분류군이었다. 불을 밝힌 점등구에서의 출현 분류군수는 비점등구에 비해 많은 개체수가 나타났으며, 두 구간에서의 동물플랑크톤 평균 출현량에서도 비점등구에 비해 점등구에서 약 $3\sim166$배 높은 출현량을 나타내었다. 본 연구에서 점등(불빛)으로 유집되는 동물플랑크톤 군집의 반응양상은 2개로 대별하여 특정지을 수 있는 것으로 나타났다. "A"그룹은 조사시기별 높은 출현 빈도를 나타낸 종들로 불빛에 명확한 양주광성(photo-positive)종들로 구성됨을 알 수 있었다. "B"그룹에 속하는 종들은 약간의 차이는 있으나, 대부분이 점등(불빛)에 소극적으로 반응하는 음주광성(photo-negative)으로 나타났다.

이 연구는 경남 통영시 도산면에서 진주조개 (Pinctada fucata) 를 1년간 양성한 시료에서 원주를 2005년 11월에 구입하여 전문가의 육안에 의해 품질.등급별로 White 컬러, Natural blue 컬러, Yellow gold 컬러로 구별하였다. 원주의 일반성분 특성은 저급의 원주일수록 Protein 함량이 높았다. 중금속의 경우, 모든 시료에서 Cr, Cu, Fe, K, Mn, Pb, Zn 등이 검출되었다. White계 원주에서 Cr, Mg, Zn, Mn 등이 낮은 등급에서 높았고, K, Fe 등은 높은 등급 원주에서 높은 경향을 확인 할 수 있었다. Zn의 경우 Natural blue와 Yellow gold 컬러에서는 높은 등급에서 함량이 높게 나타났다. 그리고 원주의 진주층 결정의 길이는 컬러에 상관없이 3-4 ${\mu}m$였고, 두께 범위는 0.28-0.34 ${\mu}m$이었다.

Ground seawater quality was investigated, and the algal growth potential (AGP) tests were performed along the Tongyeong coast to examine the inflow of materials, which is needed for the red tide species Cochlodinium polykrikoides to grow. The study was conducted to determine the mechanism for C. polykrikoidesred tides. Water temperature, salinity, pH, and dissolved oxygen (DO) ranged from 16.05 to $20.74^{\circ}C$, 18.20 to 32.11 psu, 6.00 to 7.61, and 3.41 to 7.91 mg/L (41.4-96.1%), respectively. No seasonal variation was observed in water temperature. The salinity, pH, and DO saturations at most stations were lower than those of coastal seawater at Tongyeong. The ${NH_4}^+$-N, ${NO_{2+3}}^-$-N, ${PO_4}^{3-}$-P concentrations ranged from 0.43 to 16.00 ${\mu}M$, 1.50 to 132.38 ${\mu}M$, and 1.30 to 6.29 ${\mu}M$, respectively; the values at some stations were much higher than observed in Tongyeong coast seawater. Using seawater from station B, C. polykrikoides grew consistently, with a high growth rate, similar to the red tide in nature. This seawater appeared to contain materials needed by C. polykrikoides to grow. Therefore, C. polykrikoides red tides seem to occur wherever the ground sea water contains materials that are needed for its growth.
