The worldwide abundance of various jellyfish appears to have increased in coastal ecosystems in recent years. The enormous jellyfish blooms cause a variety of problems for the local ecology, fisheries, and aquatic-sports in coastal locations. In this study, jellyfish sting protection net was installed to ensure the safety and reduction of the inflow into the Haeundae beach. In order to confirm the stability of the protection net, the tension for protection net was measured from variation of current speed. The periods for maximum tension were observed correspond to the periods of maximum current speed. The maximum tension for protection net was measured up to 4,100 kg. From field evaluations, the jellyfish sting protection net has demonstrated to stability from the current and tide in the Haeundae beach.

풍동시험에서 지지 장치는 모델을 고정하고 원하는 받음각을 구현하기 위해 사용되지만, 지지 장치가 모델에 작용하는 유동에 간섭효과를 발생시키게 되므로 이에 대한 평가와 보정이 수행되어야 한다. 본 연구에서는 스포츠급 경항공기 1/5 축소 모델의 전기체와 동체 형상에 적용된 배면스팅-반달형 지지장치의 유동간섭 효과를 더미 스팅 방법을 이용하여 공력의 변화를 측정하여 정량적으로 분석하였다. 풍동실험 결과, 하방 스팅의 유동간섭은 전기체 형상의 경우 양력계수에는 2.8%, 항력계수에는 3.4%의 영향을 끼치는 것으로 확인되었다.

The author has examined the response of sting fish, Sebastes inermis and black porgy, Acanthopagrus schlegelii to the attraction lamps(1 W) line in an experimental water tank(550 L× 58 W × 73H cm). Attraction lamp was set up at intervals of 55 cm for each section. The frequency rate was investigated at the illuminated section in accordance with the intervals of lighting on and putting out that was 1, 3 and 5 minutes under two conditions of light stimulus. The results are as follows: 1. Frequency rate at the last section when each of the attraction lamps was gradually switched on and off: (1) Sting fish was 27.2 % in case of 3 minutes interval, and 17.4 % in 1 minutes interval, and 15.8 % in 5 minutes interval. (2) Black porgy was 28.5 % in case of 5 minutes interval, and 25.8 % in 3 minutes interval, and 12.0 % in 1 minutes interval. 2. Distribution of fish at the illuminated section when each of the attraction lamps was gradually switched off after they were switched on all at once: (1) Sting fish was much gathered in the section adjacent to the extinguished section under the condition of 1 and 3 minutes interval, and not regular trend under 5 minutes interval. (2) Black porgy was much gathered last section under the condition of 1 and 3 minutes interval, and almost evenly distributed under 5 minutes interval. 3. Each of the attraction lamps was gradually switched off after they were switched on all at once, and only the last one was on: (1) The frequency rate of Sting fish was 27.2 % in case of 5 minutes interval, and 16.0 % in 1 minute interval, and 8.0 % in 3 minutes interval. (2) The frequency rate of Black porgy was 10.7 % in case of 1 minute interval, and 8.9 % in 3 minutes interval, and 0.8 % in 5 minutes interval.

대중음악은 오늘날 탈장르, 크로스오버의 조류를 타면서 다채로운 시도를 통해 클래식음 악으로의 접근을 꾀하고 있다. 그러한 시도들을 발군의 면면들로 대표하는 스팅의 음악은 진 지하고 다각적이며 논리적 구성력을 갖추고 있고, 창작 및 편곡, 연주실제의 여러 범주를 포 괄한다. 그리하여 클래식음악과의 섞임에 있어 노골성과 교묘함, 정교함을 넘나들면서, 동시 에 대중음악 고유의 음악언어와 악기, 음향(기술)을 비롯해 자신의 작업방식, 작업의도, 창작 이상을 보존함으로써 본질적, 시대적 간극을 두고 있는 두 음악장르가 서로 녹아들고 어우러 지게 한다. 이로써 다른 한편으로는 클래식음악이 다소 폐쇄적인 자기 영역을 넘어 새로운 예술적 가치와 의미를 얻어낼 뿐 아니라, 시대를 초월해 현재에 생동하는 음악으로 거듭난 다. 대중음악에 뿌리를 둔 자신의 음악적 자아를 예술음악 작곡가들의 산물에 비춰보고 또 이것들과 어우러뜨림으로써 스팅은 현대의 음악문화사에 뚜렷한 족적을 남기고 있다.
