  • 낚시의 수요가 급증하고 있는 반면에 낚시 관련 연구와 정보가 부족한 실정이며 전 세계적인 어자원 분포에 대한 데이터 확보에 한계가 있다. 기존의 어자원 분포 연구 자료의 조사방법은 조사지역에 방문하여 투망 등을 이용하여 어자원 정보를 수집하므로 국토의 소류지, 강, 바다 등 전역에 걸친 데이터 수집은 거의 불가능하다. 또한 기존의 물고기의 길이를 계측하는 방법은 줄자를 사용하였으나 본 연구에서는 피싱태그 스마트 줄자를 개발하였다. 피싱태그 스마트 줄자와 함께 사진을 기록하면 물고기의 길이, 물고기를 잡았던 환경데이터가 자동으로 데이터 수집이 되며, 줄자를 따로 가지고 다닐 필요가 없기 때문에 사용자의 편의성을 높일 수 있다. 피싱태그를 이용한 글로벌 낚시 앱 개발을 통해 첫째, 전 세계의 넓은 영역의 어자원 표본 수집이 실시간, 지속적으로 가능하다. 둘째, 어자원 데이터 수집에 대한 막대한 비용을 절감할 수 있으며 생태교란 외래어종의 분포 및 확장을 감시할 수 있다. 셋째, 전 세계적인 어자원 정보를 구글 맵을 통해 시각화하여 나타냄으로써 사용자는 위치에 따른 어자원에 대한 정보를 얻을 수 있다. 실시간으로 수집된 어자원 관련 데이터를 제공함으로 인해 다양한 연구와 정책수립에 많은 도움이 될 것이라 기대한다.

  • For the deckhouse or superstructure, attention is directed to the reduction of vibration from a human susceptibility point of view. The two basic requirements for obtaining a low vibration level in the accommodation are to ensure that excitation forces from propeller and/or main engine are small and to avoid resonance excitation of the hull and superstructure. In recent years increased attention has been directed towards the problems of vibration and noise in deckhouse, which have caused major problems with regard to the environmental quality in the living quarters for crews. Accordingly, in this paper, the characteristic of the vibration of deckhouse of fishing boat, of which the length/height ratio is also relatively high, are studied systematically with regard to the shape and modelling of deckhouse based on finite element method of 1-dimensional, 2-dimensional and 3-dimensional model. This study is divided into 4-part. 1st part is the global deckhouse vibration, 2nd part is the local deckhouse vibration, 3rd part consists of the estimation for stiffness of foundational support and 4th part is the application to TUNA LONG LINER of 416 ton class. For the global vibration analysis, the severity of the vibration depends on the longitudinal shear and bending stiffness of the deckhouse, on the vertical deckhouse support(fore, aft and sides). However, even if the design is technically sound, vibration problems may arise due to vertical or longitudinal hull girder or afterbody resonances. Author applied the method of this study to the analysis of, deep-sea fishing vessel of G.T. 416 ton class with relatively low height and long deckhouse, and investigated the vibrational characteristic of the fishing vessel with earlier structural feature. According to this investigation, the vibration, response of above vessel was confirmed of which main hull and deckhouse behave as one body. It is at the bottom of vibrational trouble which a accommodation part of the fishing vessel is raised, that is the local vibration for side wall, fore-aft wall and deck plate of deckhouse rather than thief fect of fore-aft vibration of deckhouse for above fishing vessel. and the resonance of main hull, deckhouse and driving system such as the main engine, propeller in exciting source is mainly brought up as the trouble.

  • Addressing the environmental impact of textile waste, this study explores upcycling as a sustainable fashion solution, particularly focusing on the upcycling of discarded fishing nets, which are a significant source of marine pollution. In 2018, South Korea alone produced 193.3 tons of clothing waste, refelcting a global trend, where textile waste exceedsed 92 million tons. The research methodology involved a literature review and case studies on upcycled fashion, focusing on discarded fishing nets. Designs for three outfits targeting women in their twenties were proposed and a survey was carried out to assess the their perception of upcycled fashion and the design's appeal and practicality. Under the theme, 'Marine Spirit,' the study aimed to raise awareness of marine pollution, drawing inspiration from the ocean's vibrant life. The designs diverge from the monotonous 'Casual Glam' trend, and incorporate vivid colors and asymmetrical structures for visual appeal. The practical application of fishing nets varied across the pieces, serving as fillers in transparent PVC padded coats and decorative elements in skirts and puff dresses. The distinctive properties of fishing nets provide a unique aesthetic, which resonated well with the target audience. Despite challenges in adopting eco-friendly dyeing methods and assessing mass production feasibility, the study underscores the need for continued research in sustainable textile processing. The study reaffirms the importance of sustainable fashion, highlighting the creative potential of fishing nets as a material.

  • This study has analyzed applicable characteristics on big data of the meteorology and climate depending on press releases in the media. As a result, more than half of them were conducted by governmental departments and institutions (26.9%) and meteorological administration (25.0%). Most articles were written by journalists, especially the highest portion stems from straight articles focusing on delivering simple information. For each field, the number of cases had listed in order of rank to be exposed to the media; information service, business management, farming, livestock, and fishing industries, and disaster management, but others did rank far behind; insurance, construction, hydrology and energy. Application of big data about meteorology and climate differed depending on the seasonal change, it was directly related to temperature information during spring, to weather phenomenon such as monsoon and heat wave during summer, to meteorology and climate information during fall, and to weather phenomenon such as cold wave and heavy snow during winter.

  • UN adopted the 2030 Agenda for Sustainable Development and the Sustainable Development Goals (SDGs) in 2015, a set of 17 objectives with 169 targets expected to guide actions over the next 15 years (2016-2030). One goal expressly focuses on the oceans, that is, SDG 14 'Conserve and sustainably use the oceans, seas and marine resources for sustainable development'. More than 30% of fish stocks worldwide were classified by FAO(2016) as overfished. Globally, world capture fisheries are near the ocean's productive capacity with catches on the order of 80 million metric tons. Aquaculture production is increasing rapidly and is expected to continue to increase, but aquaculture encounters some environmental challenges, including potential pollution, competition with wild fishery resources, potential contamination of gene pools, disease problems, and loss of habitat. Accordingly, there have been a variety of world organization and conferences stressing the importance of the implementation of the ecosystem-based fisheries management(EBFM) to overcome these problems. Annual catch of Korean fisheries have shown continuously declining patterns since late 1990s. Most fish stocks are currently known to be over-exploited, and some stocks are depleted due to the increase in fishing intensity and over-capitalization of fishing fleets. Other reasons for the depletion are land reclamations and coastal pollution, which destroy spawning and nursery grounds along the coastal regions. Aquaculture production is also increasing rapidly in Korea. However, several important issues such as gene pool and interaction with capture fisheries should be considered. The EBFM approach should use the best available information coupled with a reasonable application of the precautionary approach. The EBFM has global relevance, and so the real challenge will be to develop and use reliable, robust and cost-effective means of assessing and monitoring the status of ecosystems and their resources, and rapid means of detecting any undesirable and excessive impacts that threaten sustainable use. Future fisheries education should take into account UN's SDGs, which were adopted to achieve the global 2030 agenda. However, there are some difficulties in the current fisheries education system in Korea. First, the current education organizations are limited within the old frame of traditional fisheries sciences. Second, the fisheries education is currently lack of the future-oriented education system and of customized schools or departments. Third, the on-going fisheries education has been based upon few educational policies which are sufficiently relevant to holistic SDGs of the global standard. Accordingly, directions to modern fisheries education for achieving SDGs would be, first, the transition of fisheries education structure into the future-oriented and customized education system. Second, fisheries education needs to shift to the new paradigm, which combines traditional fisheries science education with related fields such as oceanography and environmental sciences to adopt the concept of EBFM. Lastly, fisheries education should accompany relevant policies for effectively achieving SDGs.
