The stow net now used in the Yellow Sea, are traditional bag net with the opening held by a lighter upper and a weighted lower beams standing against the current. Such bag net anchored at the bottom are known in many countries, particularly in the estuaries of large rivers, but more rarely in sea fisheries, because they are too much affected by the weather, moreover a permanent strong current is necessary. Some scientists intended to improve this fishing gear, using the shearing devices instead of a lighter upper and a weighted lower beams in order to widen mouth of the stow net however they are unsuccessful. One-fortieth scale model net of the stow net was tested in a circular water tank with an effective volume of 5.67m×1.76m×1.00m, with a view of observing the configuration and tension of the net. Experiments were carried out under the various combination including water velocity, spherical floats and elevating floats with the shearing hoods instead of the upper beam. We found those devices offered a very low resistance per net area to current compared with the spherical floats or upper beam, and had a fairly good shearing power at any velocity and direction of the current. the total resistance (R) of the model net to which shearing hoods and floats are attached can be induced by the following formula under the condition of 0.25m/sec to 0.5m/sec, R(kg)=3.11V^1.54 The height (h) of the improved model net (m-B) is higher than traditional model net(m-A) with upper and lower beams. m-A: h(cm)=89.22-2.42(V-15). (V ≥15, cm/sec) m-B: h(cm)=89.20-0.78V (V:cm/sec) The catch efficiency of improved model net is 1.5 times traditional model net.

A fishing simulator for towed fishing gear was investigated in order to mimic the fish behavior in capture process and investigate fishing selectivity. A fish behavior model using a psycho-hydraulic wheel activated by stimuli is established to introduce Lorenz chaos equations and a neural network system and to generate the components of realistic fish capture processes. The fish positions within the specified gear geometry are calculated from normalized intensities of the stimuli of the fishing gear components or neighboring fish and then these are related to the sensitivities and the abilities of the fish. This study is applied to four different towed gears i.e. a bottom trawl, a midwater trawl, a two-boat seine, and an anchovy boat seine and for 17 fish species as mainly caught. The Alpha cluster computer system and Fortran MPI (Message-Passing Interface) parallel programming were used for rapid calculation and mass data processing in this chaotic behavior model. The results of the simulation can be represented as animation of fish movements in relation to fishing gear using Open-GL and C graphic programming and catch data as well as selectivity analysis. The results of this simulator mimicked closely the field studies of the same gears and can therefore be used in further study of fishing gear design, predicting selectivity and indoor training systems.

Swimming Characteristics of the Black Porgy Acanthopagrus schlegeli in the Towing Cod-end of a Trawl
김용해,김치영 한국수산과학회 2005 Fisheries and Aquatic Sciences Vol.8 No.3
Fishing selectivity is determined by the level of voluntary escaping behavior in accordance with decision-making based on the relationship between fish size and mesh size. This study examined movement during the swimming behavior of black porgy in a trawl’s towing cod-end and analyzed the movement components such as swimming speed, angular velocity of turning, and distance to the net over time. Most of the observed fish exhibited an optomotor response, maintaining position and swimming speed without changing direction. Others exhibited erratic or “panic” behavior with sudden changes in swimming speed and direction. The latter behavior involved very irregular and aperiodic variations in swimming speed and angular velocity, termed “chaotic behavior.” Thus, the results of this study can be applied to a chaotic behavior model as a time series of swimming movements in the towing cod-end for the fishing selectivity.

가톨릭 신앙인 안중근이 일본왕의 특사 이토 히로부미를 하얼빈에서 저격한 사건은 당시 일본과 한국은 물론 동양국가 더 나아가 국제사회에 커다란 파장을 던졌다. 100년이 지난 오늘에도 안중근은 역사에 살아서 동양평화를 이야기하는 모든 이에게 영감을 주고 있다. 본 논문은 현대 가톨릭교회의 평화론을 기준으로 그의 삶과 행동을 조명하고 평가해 보고자 한다. 현대의 기준으로 100년 전의 인물을 평가해 보려는 시도는 그가 시대를 앞서 간 위인이었음을 인정할 수밖에 없는 분이라는 것을 전제하는 것이다. 가톨릭 교회의 평화론에서는 전통적인 네 가지 원칙, 인간존엄성, 공동선, 연대성, 보조성 등의 원리를 살피고 갈등 속에서도 평화를 건설하는 프란체스코 교황의 네 가지 내적 태도를 소개한다. 그리고 이러한 원리와 태도가 안중근의 사상과 삶과 죽음 속에서 어느 정도 구현되었는지 조명한다. 이 조명작업은 그의 자서전과 재판 및 복역과정의 청취서를 참고하면서 그의 양심적 고뇌와 평화와 정의를 지향하는 마음이 가톨릭 신앙 안에서 어떻게 결합되었는지를 드러낸다. 그러고 나서 ‘좋은 삶’이란 무엇인지에 대한 물음으로서의 윤리학적 입장에서 그의 거사를 평가한다. “견리사의 견위수명(見利思義 見危授命: 이익을 보면 의로움을 생각하고, 위험을 보면 생명을 내어준다). 그가 남긴 이 글이 제국주의의 침략 속에서 백성들이 고통을 당하는 상황에서 자신의 이로움을 구하지 않고 더 평화롭고 자유로운 세상을 만들기 위해 교육과 의병활동에 투신하였고 마침내 불의에 항거했고 교수형에 처해진 그의 삶을 잘 요약한다.
