In this paper, we propose digital exhibition contents for the aquarium, especially 'Gyeongpo Lagoon Ecological Museum'. We try to plan appropriate media contents that can be mixed with the aquarium storytelling. The aquarium must have special spaces that are not related with an exhibition directly but are necessary for survival of fishes such as a water circulation room. We design the special spaces using media contents and let visitors feel that the whole aquarium is in the ocean. First of all, we investigate the aquarium currently under construction. And then, we propose the appreciate media platforms and plan individual content. We suggest 3 types of media platforms, 3D water projection, interactive games utilizing Kinect, and a fog screen. Moreover, we produce 2D drawing concepts, 3D modeling images, and virtual exhibitions in virtual reality for the representation of the location in which those platforms are installed and the media contents we plan. The pre-visualization is helpful for the media platform construction and is used as a rough sketch to producing an animation shown in the exhibition.

It is worth it to properly present the behaviors of cyberspace and game characters. It is not so easy to manually supply the actions for all objects one by one, so we need to use crowd animation techniques in order to display automatically, realistically, and effectively. In this paper, we construct a ubiquitous cyber aquarium based on sensors, using the crowd behavior library, which is applied to programming crowd behavior in cyberspace and game applications. We use a sensor board to become aware of a person approaching the cyber aquarium, and according to the perceived distance, the objects in the cyber aquarium automatically react and behave accordingly.

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.

In a cyber aquarium, the behavior of fish objects is the most important factor in respect of visual effects. 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 cyber aquarium, the 3D aquarium screen saver, and the cyber fish game, and so on.

In this paper, the designed fish robots DOMI ver1.0 is researched and development for aquarium underwater robot. The presented fish robot consists of the head, 1'st stage body, 2nd stage body and tail, which is connected two point driving joints. The model of the robot fish is analysis to maximize the momentum of the robot fish and the body of the robot is designed through the analysis of the biological fish swimming. Also, Lighthill was applied to the kinematics analysis of robot fish swimming algorithms, we are applied to the approximate method of the streamer model that utilizes techniques mimic the biological fish. The swimming robot has two operating mode such as manual and autonomous operation modes. In manual mode the fish robot is operated to using the RF transceiver, and in autonomous mode the robot is controlled by microprocessor board that is consist PSD sensor for the object recognition and avoidance. In order to the submerged and emerged, the robot has the bladder device in a head portion. The robot gravity center weight is transferred to a one-axis sliding and it is possible to the submerged and emerged of DOMI robot by the breath unit. It was verified by the performance test of this design robot DOMI ver1.0. It was confirmed that excellent performance, such as driving force, durability and water resistance through the underwater field test.

The purpose of this paper is to estimate a probability to visit the Yeosu Aquarium with an ordered logit model. Ordered logit model is affordable to estimate the probability when the dependant variable represents likert-type scale. The estimated results are as follows. The more income induces the visiting-expectation. The experience for another aquarium and the visiting-expectation for the Yeosu EXPO are contributed to the visiting-expectation for the Yeosu Aquarium. The needs to visit the Yeosu Aquarium is low in Kyoungsang area and Seoul-Kyounggi-Incheun Metropolitan area. This is related to the Aquarium facilities, which were established in each area. In average level conditions regarding to all independent variables the probability to visit the Yeosu Aquarium is calculated to 15.75%. However, the probability to visit to the Yeosu Aquarium is decreasing according to the change of an admission fee.

The interest in the service of 3D mobile contents becomes larger due to the technological advance of production and services of mobile contents and the appearance of the exclusive mobile phone for 3D game. Therefore, the researches about the efficient mobile services of large 3D contents are wanted in the circumstances of the narrow bandwidth and the burden of the connection charge of wireless mobile communications. In this paper, we suggest a strategy of caching for looking up and downloading the 3D marine characters efficiently and a system model for mobile service of 3D marine characters. The suggested system is designed for serving efficiently the high-quality 3D characters through the wireless mobile communications using the database on the 3D marine objects of cyber aquarium constructed for the services through the wired internet.

A CCD camera and an LED light source were combined to fabricate a compact optical CT scanner for the therapeutic radiation dose evaluation of a polymer gel dosimeter. After the collimated beam emitted by the LED passed through aquarium, gel phantom, and telecentric lens, an image was collected by the CCD camera and reconstructed using MATLAB. By using a stepping motor and LabVIEW, the gel dosimeter was rotated at every $0.72^{\circ}$, and the time for collecting 500 slice images per a revolution was within 20 min. At a spatial frequency of 4.5 lp/mm of the optical CT scanner, the modulation transfer function value was 72%. The linear correlation coefficient of the optical CT scanner for the polymer gel dosimeter was 0.987.

Shark populations are constantly decreasing owing to environmental destruction and overfishing; thus, sharks are now at risk of extinction, with 30.5% of species classified as endangered on the International Union for Conservation of Nature's Red List. Sharks are apex predators and keystone species in balancing the marine food chain; their extinction would create an imbalance in the entire marine ecosystem. Assisted reproductive technology is a last resort for protecting animals facing extinction. Here, as a proactive effort toward building a hormone-induced artificial insemination protocol for endangered wild sharks, we identified the possibility of germ cell maturation by administration of GnRH, a commercially produced synthetic salmon gonadotropin-releasing hormone, and calculated its optimum dosage and injection timing. The experiment was conducted on one shark species, Chiloscyllium plagiosum. Injections were administered in 24 h intervals to C. plagiosum females, and 0.2 mL/kg+0.2 mL/kg were the optimal doses. These doses effectively induced maturation and, and ovulation, and oocyte release. Our results confirm that GnRH is a suitable tool for shark hormone-induced artificial insemination and indicate that this method may facilitate the conservation of endangered shark species.
