디지털 캐릭터 리깅은 애니메이션의 생동감을 높이는 중요한 기술이며, 다양하고 복잡한 방식의 리깅 시스템이 많다. 이에 자연스러운 움직임을 위한 모션 테스트를 물고기로 진행한다. 왜냐하면, 2족, 4족 캐릭터의 자료들은 더러 있으나, 물고기(0족) 움직임에 관한 연구의 자료는 많이 없다. 물고기 움직임 제작의 다양성과 복잡성이 증가하면서 비효율적인 시간과 자본도 요구된다. 물고기 특성에 맞는 골조 시스템을 어떻게 만들 것인지는, 어떻게 효율적이고 민첩한 리깅 프로세스를 만드느냐에 달려있다. 본 연구는 높은 시간비용의 리깅 기술 문제를 해결할 수 있는 어드밴스드 스켈레톤(Advanced Skeleton) 기반의 애니메이션 리깅 제작 프로세스와 Maya Rig를 비교하여, 어드밴스드 스켈레톤(Advanced Skeleton)의 장점을 활용해 최적의 자동 리깅 툴을 모색하고, 물고기 애니메이션 연구 범주를 넓힐 것에 목적을 두고 있다.

As grouting materials for ground improvement, silicate materials such as water glass, silica-sol and so forth are used worldwide. However, they may pollute underground water. In this study, fish poison test(Korean standard industrial code KS M 0111) which estimates toxicity for fish is applied to evaluate the toxic effect by grouting materials. From the test result of the sample made of LW, LC50(Median Lethal Concentration) reaches within 24 hours. In case of the silica-sol, it does not even in 96 hours. Therefore, we can conclude that the sililca-sol grouting method is more free from the danger of underground water pollution. From the result that the mortality of fish under the condition of pH 8.6 is 0% within 96 hours, the groundwater can be saved by controlling pH below 8.6 for the grouting in the field.

The main objective of this paper is to control a trajectory tracking of the fish-mimetic robot by CPG (Central Pattern Generator), which is biological approach. CPG is biological neural networks that generate rhythmic movements for locomotion of animals, such as walking, running, swimming and flying. Animals show marvelous ability of autonomous dynamic adaptation for an unsteady fluid dynamic environment or various environments. So, we propose the 3-DOF CPG controller to track the trajectory of the fish robot in plane motion. The conformity of the proposed control algorithm is validated by simulation for a fish robot model, which is made by a commercial dynamic package.

하천과 같은 생태계와 생물 서식지 들은 생물학적 요소와 무생물학적 요소간의 다양한 상호작용을 포함하는 복잡한 관계를 맺고 있다. CASiMiR 모델은 선정된 특정종의 서식지 적합도를 결정하기 위해 하천시스템의 수리학적 및 지형학적 특성을 사용하는 모듈형식의 조합으로 모의를 실시하는 프로그램으로 입력되는 자료로는 수심, 유량 등의 수리학적 자료와 하저구성물의 크기 토지피복의 종류 등의 지형학적 자료 등이 필요하다. 또한 어류의 서식지 적합도 지수를 제공하기 위해 선호도 함수를 사용하거나 Fuzzy 모형을 사용한다. 본 연구에서는 이러한 CASiMiR-Fish 모형을 이용해 피라미 종의 Fuzzy 함수로 수통 수위표 지점 상하류 3km 구간에 대한 어류 서식지 모의를 실시하였다.

Although cultured sweet smelt production recently have been rapidly increased from 89 metric tons (M/T) in 1997 to 500M/T In 1999 in Korea, wild fish have been still used as broodstock for cultured fish seed. This is considered due to having higher sperm and e99 qualify in wild fish broodstock than cultured fish. However, capturing a number of wild sweet smelt broodstock might lead to decreasing of the production of wild fish, In truth, of which production has been greatly decreased so that a number of artificial juvenile have been stocked some rivers in Korea.

This paper describes about a technique of generating music from the natural motion of fish which are detected via the running averaging background subtraction method. The motion of the fish will create musical notes on a background frame which will be analyzed and played by a music playing module that is proposed in this paper called "PhysicX". This module is also capable of interacting with the fishes. in the tank.

In the natural course of events, most human exposure to MeHg is through fish/shellfish consumption. The methylmercury exposure levels depends on the amount and species of fish/shellfish consumed daily. The developing brain in the late gestation period is known to be most vulnerable. Further, more methylmercury accumulates in the fetuses than in mothers. Therefore, efforts must be made to protect the fetuses from the risk of methylmercury, especially in populations which consume a lot of fish/shellfish.

The use of transgenic fish has so far been chiefly limited by the lack of predictable, strong, tissue specific, and position-independent expression of transgenes. For genetic analysis, expression of a marker transgene, easily screenable in the living fish, could facilitate studies of gene targeting, insertional mutagenesis, lineage, and mutational analysis.

Although flounder is one of the most important marine fish for aquaculture in Korea, feeding the flounder in commercial farms depends mainly on moist pellet in which over 70% frozen fishes (e.g. frozen horse mackerel) are incorporated in its formulation. Therefore, for further expansion of flounder farming, it is essential to employ practical formulated feeds that can support reasonable growth. Development of nutritionally balanced and cost-effective feeds is dependant on the information about nutritional requirement and feed utilization of the species. Nutrient and energy source in feed are needed for the growth and maintenance of fish. Protein is probably the most important nutrient affecting fish growth and feed cost. Therefore, it is essential to determine the optimum dietary protein level for the growth of fish, both its high proportion in the feed and because it is the main factor in determining feed cost. Dietary energy level is also critical because protein source in the feed is utilized as an energy source when the feed deficient in energy is fed to fish, whereas when the feed excess in energy is fed to fish, feed consumption decreased and resulted in growth reduction due to lack of other necessary nutrients for normal growth. Improper dietary protein, energy levels and/or their ratio will lead to an increase of fish production cost and deterioration of water quality resulting from wasted feed; thus, they are important in formulating commercial feed. Dietary lipids play important roles in providing energy and essential fatty acid for normal growth and survival of fish. Although carbohydrates are not essential nutrients for carnivorous fish, these compounds play important roles as a low-cost energy source for protein sparing and also as a feed binder. Nutrition researches for flounder have identified its requirements of protein, lipid and essential fatty acid, vitamin, and minerals for normal growth. Other studies have also been carried out to investigate the utilization of the protein, lipid and carbohydrate sources. Based on these nutritional information obtained, practical feed formulations have been studied for improve aquaculture production of flounder. The results of the researches on utilization of dietary protein, lipid and carbohydrate by flounder are discussed in this review.
