Marine fish aquaculture has been introduced on the East sea since 1964. The production volume of the marine aquaculture has been increasing drastically since 1990 with the technological improvements and the introduction of new species. However, the increasing costs of feed, seedlings and medical supplies and the decreasing prices due to the increase in the imports and domestic production have decreased the profits in the aquaculture business. Futhermore, the damage from the natural disasters such as red tides and typhoons has accelerated the exit from the business. Even though managing abilities to overcome the business crisis caused by the above factors are required, business managers based on the small scale family businesses do not have enough managing abilities to deal with the difficulties in the business. On the other hand, advanced countries in the marine aquaculture such as Norway have reached the stage where the managing abilities of marine aquaculture are similar to those in the manufacturing industry. And the number of large scale aquaculture farms with developed technologies and advanced marketing strategies in those countries is increasing. Considering that the marine aquaculture in Japan under the similar fishery systems of Korea has developed the state-of-the-art management skills or lead to large scale management, it is difficult to expect the decrease in the production costs under the small scale family business in Korea and this will lead to the decreasing competitive advantage over the imported seafood. Therefore marine aquaculture in Korea needs to increase the economy of scale to acquire the competitive advantage. This study addresses the possibility of introducing the large scale aquaculture system in Korea by analysing the factors and process of leading to large scale businesses in the aquaculture in Japan.

Keeping qualities of crude proteases (CP) and fractionated proteases (FP) sedimenting with $30\~80{\%}$ ammonium sulfate from four kinds of fish viscera as a seafood processing waste were examined. Azocaseinolytic activlties (pH 6 and 8) of CP from anchovy (Engraulis japonica), mackerel (Scomber japonicus), bastard flatfish (Pararlichthys olivaceus) and red sea bream (Chysorphys major) were stable without activity loss at $4^{\circ}C$ for 7 months. Activities of NaCP (CP containing $30{\%}$ sodium chloride) on azocasein were approximately $30{\%}$ lower than those of CP. FP activities Increased 3.4-16.1 folds compared to those of CP and NaCP Powdered crude protease (PCP) and fractionated and powdered protease (FPP) containing various sugars (lactose, sucrose, glucose and dextrin) were prepared by freeze drying. Activities of PCP and FPP containing sucrose were higher and more stable than those of PCP and FPP containing other sugars at $30^{\circ}C$ for whole keeping periods. PCP and FPP from mackerel viscera showed the highest proteolytic activity among four kind of fish vlsceras. The Optimum conditions and stabilities of FPP from mackerel viscera were pH 9 and $50^{\circ}C$, and pH 5-10 and $20-45^{\circ}C$, respectively. The results of this study suggest that FPP from seafood processing waste may be used as processing aids.

앙골라분지 심해시추연구(DSDP) 정점 530에서의 중기 백악기층은 유기탄소의 함량이 풍부한 흑색셰일과 유기탄소의 함량이 빈약한 적색 및 녹색의 점토암이 주 기적으로 교호한다. 이들 흑색셰일층의 퇴적환경을 밝히기 위하여 이들 중에 함유 된 불용성퇴적 유기물(Kerogen)의 종류 및 그 분포에 관하여 분석하였다. 앙골라분 지 백악기 흑색셰 일층에 함유된 유기물의 종류는 대부분 무정형유기물(Amorphous Organic Matter)로서, 이들의 주된 기원은 부유성 해양 조류. 즉 화석화되지 않은 해양 부유성 쌍편모충류로 추정되었다. 이들 부유성 조류는 환경의 변화에 따라 주 기적으로 다량 번식하여 앙골라 심해저로 공급됨으로써 , 백악기 당시 용존산소의 농도가 현재보다 훨씬 낮고 폐쇄된 환경의 앙골라 심해저에 환원환경을 주기적으로 야기시켜 유기물의 집적을 용이하게 함으로써 흑색셰일층이 형성되었음이 추측된 다.

이 글은 홍콩 출신 감독 린차오셴(林超賢)이 중국의 주선율 영화에 어떤 변화를 가져왔는지, 그리고 이러한 변화에 영향을 미친 요소들을 분석하기 위한 것이다. 분석의 대상은 린차오셴(林超賢)의 영화 <오퍼레이션 메콩>(湄公河行動, 2016), <오퍼레이션 레드 씨>(紅海行動, 2018), <긴급구원>(緊急救援, 2020)이다. 린차오셴은 중국 대륙 감독들에 비해 정치적 부담이 크지 않아 상업영화의 모델을 이용해 주선율 영화를 만들고 홍콩영화의 요소를 주선율 영화에 최대한 활용하고 있다. 그 결과 주선율 영화의 이데올로기는 딱딱한 표현이 아니라 관객의 공감을 불러일으킬 수 있는 다원화된 가치를 보여준다. 사실적이고 복합적인 인물은 과거 고정 천편일률적이며 비현실적이었던 영웅의 이미지를 대체한다. 스펙터클한 액션 장면과 폭력적인 장면의 응용이 시각적 진풍경을 만들어낸다. 그 결과 주선율 영화는 더 높은 상업적 가치를 얻었다. 린차오센의 영화는 새롭게 변화하는 관객의 취향이 영화산업에서 중요한 요인임을 확인시켜주었으며 높아진 제작비와 더불어 민영영화사의 역할을 키우고 있다.

COVID pandemic has reshaped the world as it has been known to us and the education system is one of the most affected by it. Due to social distancing, quarantines and isolations have made it impossible for the knowledge transition to the masses using conventional methods. For cope with pandemic, the only other way available for some of the fortunate countries is the use of E-learning having somewhat the same traditional teaching method. This paper is concerned with the study of the preparedness of the learning system in some Sudanese universities due to the impact of the COVID-19 pandemic. Critical analysis has been performed to evaluate the current developing scenario, usage of the facilities available in open-source platforms, and the interaction of the universities folks with e-learning systems. The impact of such measures has been thoroughly investigated in this paper for Sudan which is already deprived of a proper education system. The investigation shows that the interact of the staff and the students with the system was acceptable where more than 85% of those enrolled to the system were interact properly and efficiently. The lecturers conducted through the platform were attended with more than 75% of the students. We also found that most of the lecturer were avoid to exam students by utilize the platform; where only 45% of the uploaded courses were conducted exams over Moodle platform. As Moodle is an open source and still need to be improved to be used for high examination credibility.

As a series of basic research to draw the pilot design measures for developing the habitat apparatus of Sulculus diversicolor supertexta inhabiting the coastal area of Jeju island, this study conducted a water tank experiment to understand the habitat marine environment of Sulculus diversicolor supertexta and the preference of habitat space focusing on the research fisheries performing the discharge of marine products. In the composition degree of marine algae in both fisheries, Donggwi-ri showed the highest gulfweed (79.3%) as brown algae and there were some coralline algae (17.2%) as red algae. Hansu-ri yielded the highest gulfweed (48.1%) as brown algae, which was followed by sea lettuce (10.4%) as green algae. In the preference of habitat space, the shelter angles 40° showed the highest adhesion as number of 82.9, which was followed by 60° and 70° as 69.2 and 68.2 respectively (P<0.05) by reviewing the environmental characteristics of habit of Salculus diversicolor supertexta in the coastal fishery of Jeju Island, when considering the adhesion rate in each of five shelters with different angles. In the future, there should be continuous research and monitoring for designing the fish shelters suitable for the coastal fisheries of Jeju island, and it would be also necessary to add the field-centered sustainable concrete research.

본 연구는 울릉도 수산자원 감소 문제를 해결하기 위한 방안 중 하나로서 정치성 구획어업의 도입을 위한 시험 연구를 수행하였다. 시험용 어구인 삼각망은 울릉도 해역의 환경, 운영 및 관리 비용, 소형 어선 및 인력이 운영할 수 있는 조건을 고려하여 선정하였다. 2017년 4월부터 5월까지 삼각망을 이용하여 11회 어획 조사한 결과, 총 개체수는 2,735개체, 중량은 983.4 kg으로 계측되었으며, 우점종은 참돔, 방어, 넙치, 한치, 전갱이, 쥐치류 등으로 조사되었다. 조사기간 중 유용 수산자원은 어류의 경우 조피볼락(Sebastes schlegelii), 볼락(S. inermis), 개볼락(S. pachycephalus), 쑤기미(Inimicus japonicus), 노래미(Hexagrammos agrammus), 농어목 어류 붉바리(Epinephelus akaara), 참돔(Pagrus major) 그리고 말쥐치(Thamnaconus modestus)로 분류되었으며, 두족류인 한치(Uroteuthis chinensis)의 어획량이 많은 것으로 분석되었다. 울릉도의 주요 수산자원 중 하나인 살오징어의 생산량이 지속적으로 감소할 경우, 삼각망과 같은 소형 정치성 구획어업의 도입은 어민 수입 창출의 대체 수단으로 유용할 것으로 판단된다.
