As time spent in front of the computer screens increases, an increasing number of people are using natural landscapes or virtual aquariums as their desktop and screen saver that can provide them with mental comfort. A virtual aquarium is constructed by an animation work that creates a variety of fish that freely move in a random virtual underwater environment to analyze their movement. This paper suggests a method that constructs an immersive virtual aquarium, using fluid animation method that expresses changes of shape of fluid in real time and the Smart Fish technology which is capable of an interaction according to the diverse characteristics of virtual fish. The suggested method can be used in a virtual aquarium, aquarium screen saver, virtual fish-raising game, etc., which express diverse undersea environment.

Changes in nucleotide concentrations of aquarium-stored flounder, sea bass, and sea bream were studied. ATP, ADP, and AMP slowly decreased, whereas IMP, HxR and Hx slightly increased with increasing storage ported. ATP was converted into IMP at initial storage stage. Changes in concentrations of nucleotides differed depending on fish type and season. Freshness indicators, $K,\;K_{p}\;G,\;P,\;H,\;and\;F_{r}$ values during 14 days storage showed no significant differences. Changes in nucleotide concentrations during 14 days storage had no significant effect on taste of raw fishes.

The interaction between artificial fish and aquatic surroundings and the fish's realistic locomotion are very important elements to construct virtual aquariums. In general, the artificial fish in virtual aquariums used to be created by 3D modeling tools, and was repeatedly showing the simple and constant form of swimming. This paper will analyze the sorts of biological forms of fish-swimming and the propelling and turning characteristics. Then, we propose a method of the basic swimming and turning of artificial fish to generate various and natural-looking locomotion. It is possible to make a explorable virtual aquarium more immersive by using interactive interfaces together.

가족끼리 놀러 가기로 했다. 한 아이는 수족관, 다른 아이는 동물원을 가자고 조른다. 부모는 어느 쪽으로 선택해야 할지 난감하다. 이럴 때 수족관과 동물원이 한 공간에 있다면 얼마나 좋을까? 이런 부모들의 마음을 헤아려 수족관과 동물원을 한 공간에 마련한 아쿠아리움이 있다. 지난 4월에 개장한 '한화 아쿠아플라넷 일산'이다. 아쿠아플라넷 일산은 국내에서 해양생물을 관람할 수 있는 63씨월드, 코엑스 아쿠아리움, 제주, 여수에 이어 다섯 번째지만 동물원과 수족관이 결합된 단일시설로는 국내 최초이며, 수도권 최대 규모의 아쿠아리움이다. 해양생물을 관람하려면 서울로 와야 하는 수도권 이북지역의 관람객을 겨냥했으며 호수공원, 국제전시단지, 한류월드로 이어지는 매머드급 접객시설이 밀집되어 있고 일산 킨텍스, 주엽역과 일산 꽃박람회장까지 연결되는 접근성이 뛰어나 전시단지의 상징적인 랜드마크로서 자리잡을 전망이다.

The invasive red swamp crayfish, Procambarus clarkii, is native to south-central United States and northeastern Mexico. Recently, it has been being spreading in the wild in South Korea. However, its primary sources, introduction routes, establishment, and expansion in South Korea remain unclear. Here, we analyzed genetic diversity and population genetic structures of its domestic natural populations during early invasion, commercial stock from local aquaria (a suspected introduction source), and original United States population using mitochondrial COI gene sequences for 267 individuals and eight microsatellite markers for 158 individuals. Natural and commercial populations of P. clarkii showed reduced genetic diversity (e.g., haplotype diversity and allelic richness). The highest genetic diversity was observed in one original source population based on both genetic markers. Despite a large number of individuals in commercial aquaria, we detected remarkably low genetic diversity and only three haplotypes among 226 individuals, suggesting an inbred population likely originating from a small founder group. Additionally, the low genetic diversity in the natural population indicates a small effective population size during early establishment of P. clarkii in South Korea. Interestingly, genetic differentiation between natural populations and the United States population was lower than that between natural populations and aquarium populations. This suggests that various genetic types from the United States likely have entered different domestic aquariums, leading to distinct natural populations through separate pathways. Results of our study will provide an insight on the level of genetic divergence and population differentiation during the initial stage of invasion of non-indigenous species into new environments.

In a virtual aquarium, the behavior of fish objects is the most important factor in respect of visual effects. In addition to the individual behavior of fish object, the interactions between objects due to their attributes, can improve the dynamics and reality of the virtual world. In this paper, we analyze the principal habits of fish objects such as the vitality, the range of movement, the maximum depth of water they can live, and the cycle of eating. Then, we suggest a method for simulating the stable marine ecosystem with controlling the behaviors, the interaction with other species, the average span of life, and all that sort of thing based on the result of analysis. Because we can freely modify the behavior of fish object by altering the values of attributes, it can be utilized in the dynamic virtual aquarium, the 3D aquarium screen saver, and the virtual fish game, and so on.

본 논문에서는 일반적인 수족관에서 물고기를 관찰하는데 있어서 관찰자가 빠르고 효율적으로 물고기에 대한 정보를 얻을 수 있는 방법을 제안하고자 한다. 여러 종의 물고기가 살고 있는 수족관 환경에서 처음 보는 관찰자과 쉽게 물고기에 대한 정보를 얻기는 힘들다. 이러한 제약을 효과적으로 개선하기 위하여 반 투영 거울을 사용하는 공간 증강 현실을 위한 영상출력 기법을 이용한다. 이때 피사체의 위치 정보를 얻기 위해 배경인 수족관영상과 피사체인 물고기영상을 분리한 후 물고기의 깊이 정보 값을 추출하기 위하여 호모그래피 행렬을 이용하고 보정된 이미지를 계산 한다. 실험결과 본 논문에서 제안한 방법을 통해 구축한 이 시스템으로 관찰자는 각각의 물고기들에 대한 정보를 반응형 Annotation으로 쉽게 얻을 수 있었다.
