부산 수영강 하구에서 채집된 점성어, Sciaenops ocellatus의 첫기록
김태주,김진구 한국어류학회 2025 한국어류학회지 Vol.37 No.2
2024년 8월 6일과 9월 24일에 부산광역시 수영강 하구에서 낚시로 점성어 2개체 (체장 581.0 mm, 체장 240.7 mm)가 채집되 었다. 야생에서 포획된 점성어를 공식적으로 보고하는 것은 이번 이 처음이다. 점성어 2개체는 D. XI, 23~24; A. II, 8~9; P1. 16; P2. I, 5; 꼬리자루에 1~2개의 큰 둥근 검은 반점을 가지는 특징 에 의거 점성어로 확인되었다. 우리의 발견은 양식장에서 탈출한 점성어가 야생에서 생존하고 번식할 수 있음을 시사하며, 본 종 이 활발한 포식자에 속하기 때문에 해양생태계에 미치는 영향에 대한 추가적인 모니터링이 필요하다. Two individuals (240.7 mm and 581.0 mm in standard length) of red drum (Sciaenops ocellatus) were caught by angling in Suyeonggang River estuary, Busan, Republic of Korea on 6 August and 24 September 2024. This is the first official record of an introduced red drum being caught in the wild of Korea. The specimens were well matched with characteristic of red drum in terms of morphological traits: D. XI, 23~24; A. II, 8~9; P1. 16; P2. I, 5; 1~2 large black rounded spots present in the caudal peduncle. Our findings suggest that the red drum escaped from aquaculture farms can survive and reproduce in the wild, and since this species belongs to active predators, further monitoring of its impact on marine ecosystem is required.
어음上의 權利義務의 成立과 어음의 交付에 관한 學說 比較
金泰柱 慶北大學校 1977 論文集 Vol.23 No.-
How is the right and obligation in a bill of exchange? Does the making of the paper alone suffice, or does it require delivery of the instrument, following its making? The creation theory says that the right and obligation is already effectually created by making the paper alone even before its delivery to the other party. The issuance theory on the other hand says that the right and obligation in the paper is completely created by the making of it alone as asserted by the creation theory, however that the paper must be put in negotiation to someone at the maker's intention. The contract theory asserts that delivery of the paper is agreed among the parties and actually delivered more than the making of the paper. According to the contract theory, however, the maker of paper is held not liable, when the paper is lost or stolen and in due course come into the hand of bona fide purchase. I am in agreement contract theory that constitution of obligation in a bill of exchange is completed by delivery of paper to the party and the maker of paper should be help liable by 'Rechtsscheintheorie' (estoppel), when the paper is lost or stolen and in due course come in to the hand of b. f. p. The reason is that contract theory is most suitable on actuality of delivery of commercial paper. This problem has been one of the most contravercial ones among Scholars of commerial papers. This article has seriously reviewed the theories concerning the constitution of right and obligation in a bill of exchange, and in addition thereto, the liability of the signer as arisen in case of lack of its delivery is discussed.
