사이버 공간 및 게임 콘텐츠 상에 존재하는 수많은 캐릭터의 행동을 표현하기 위하여 개개의 움직임을 수작업으로 일일이 제작하여 제공하는 것이 거의 불가능하고 비효율적이기 때문에 이를 자동화하여 보다 사실적이고 효율적으로 표현하기 위해서는 군집 애니메이션 기술이 필요하다. 본 논문에서는 프로그래머가 가상현실이나 게임 응용 프로그램에서 군집행동을 프로그래밍 하는데 직접 활용하기 위한 군집행동 라이브러리로 사이버 아쿠아리움을 구현하고, 사람이 사이버 아쿠아리움으로 접근하는 것을 거리로 측정하는 센서 보드를 제작하여 물고기들의 능동적인 군집 행동을 유발하는 센서 기반의 유비쿼터스 사이버 아쿠아리움을 구축한다

Of 643 aquarium water samples, 374(58.2%) were less than 1.0$\times$103 SPC/ml, seasonally, were 56.7% of samples in Spring. 38.7% in Summer,84.5% in Autumn, and 57.7% in Winter, respectively. a1so 3(0.47%) were over 1.0 $\times$ 105. E.coli and V. parahaemolyticus distribution was relatively high when SPC/ml was much. At the aspect of the water quality management, 98.3%(177/181) were cleaned over once a week. 69.1%(125/181) were cleaned over twice a week.

This study was performed to analyze the fluid flow characteristics and the temperature distribution of the aquarium for fish breeding. In this study, the finite volume method and turbulence k-$\varepsilon$ model with the SIMPLE computational algorithm are used to study the water flow in the aquarium. The calculation parameters are the circulating flow rate and the basin depth, and the experiments were carried out for the water flow visualization This numerical analysis gives reasonable velocity distributions in good agreement with the experimental data. As the results of the three dimmentional simulations, the sectional mean velocity increased as the sectional mean temperature increases for constant basin depth, and the mean velocity increased more rapidly for small basin depth than that of large basin depth, The mean velocity and temperature can be expressed as the function of the circulating flow rates and the basin depth.

This paper realizes control of the motion of a swimming robot fish in order to implement an underwater robot fish aquarium. And it implements positional control of a two-axis trajectory path of the robot fish in the aquarium. The performance of the robot was verified though certified field tests. It provided excellent performance in driving force, durability, and water resistance in experimental results. It can control robot motion, that is, it recognizes an object by using an optical flow object-detecting algorithm, which uses a video camera rather than image-detecting sensors inside the robot fish. It is possible to find the robot's position and control the motion of the robot fish using a radio frequency (RF) modem controlled via personal computer. This paper proposes realization of robot fish motion-tracking control using the optical flow object-detecting algorithm. It was verified via performance tests of lead-lag action control of robot fish in the aquarium.

The results of study of the parasites of rockfishes, Sebastes spp. collected at Oregon coast aquarium during April 6 to June 30, 2002 are presented. Six species of parasites were recovered from examination of 19 rockfishes with an incidence of infection of 42.1 %. This study investigated parasitic infestation of 7 black rock-fish, Sebastes melanops ; 3 quillback rockfish, S. maliger ; 2 yellowtail rockfish, S. flavidus ; 3 canary rockfish, S. pinniger 2 yelloweye rockfish, S. ruberrimus ; 2 tiger rockfish, S. nigrocinctus. Sebastes spp. from aquarium were found to be infested with parasites: Mycrocotyle sebastis, Megalocotyle trituba, Clavella uncinata, Anisakis simplex larvae, Contracaecum sp. larvae, Pseudoterranova decipiens larvae. Prevalence and mean intensity of rockfishes were infected respectively as follows: 21.1%, 4.0 of M. sebastis, 10.5%, 55.5 of M. trituba, 21.1%, 34.3 of A. simplex larvae, 10.5%, 15.0 of Contracaecum sp. larvae, 10.5%, 8.5 of Pseudoterranova decipiens larvae and 10.5%, 5.0 of Clavella uncinata. This study reveled that gills and gastrointestinal tracts of S. pinniger were heavily infested with M. trituba and A. simplex larvae.

사이버 아쿠아리움을 구성하는 요소들 중 어류 객체의 행동방식은 사용자의 시각적인 측면에서 가장 중요한 요소이다. 본 논문은 어류 객체들의 생명력, 이동량, 분포 가능한 최대 수심 및 식성 주기 등의 주요 습성들을 분석하고, 이에 따른 움직임, 다른 어류 객체들과의 상호작용, 평균 수명 데이터를 조정함으로써 해저 생태계의 균형을 시뮬레이션 하는 방법을 제안한다. 제안 방법은 어류 객체의 고유 속성값을 자유롭게 변경시킴으로써, 다양한 해저환경을 표현하는 사이버 아쿠아리움, 수족관 화면 보호기, 물고기 육성 게임 등에 활용되어질 수 있다.

조개와 수컷의 유무, 암컷 단독, 수조의 크기, 수조당 개체수 등과 같은 조건 하에서 각시붕어 (Rhodeus uyekii)의 산란관의 신장에 대하여 조사하였다. 각시붕어 암컷의 산란관은 조개, 조개+수컷, 수컷의 조건에서 모두 산란관이 주기적으로 신장하였으며, 암컷 단독으로 존재하는 상황에서도 신장되는 경우가 많았다. 조개와 수컷 없이 암컷만 사육하였을 때 큰 수조에 1개체를 넣은 경우에는 산란관이 신장되지 않았지만 작은 수조에 1개체 혹은 큰 수조에 여러 개체를 넣은 경우에는 신장이 일어났다. 신장된 상태의 지속기간은 1~3일 (평균 1.2~2.5일)이었으며, 신축주기는 4~15일 (평균 6.4~11.9일)로 나타났다. 신장되었을 때의 산란관의 길이는 68~100% (평균 78.5~98.8%)이었다. 주기적 신축기의 축소시기에 산란관의 길이는 20~51% (27.3~33.1%)이었으며, 더 이상 신축하지 않는 시기의 산란관의 길이는 3-30% (평균 11.1~19.9%)이었다. 수조의 크기와 개체수가 산란관의 신장에 미치는 영향 및 기존에 보고된 다른 종의 산란관의 신장과의 관계를 논의하였다.

This research has been performed by our own investigation, also cooperated with Health and Sanification Division and each of district offices in Busan metropolitan city. After choosing, we collected water samples five times for microbiological examination. As a result of investigating in 160 water samples from urban areas, we could detect 88 cases of Vibrio spp. Furthermore, there were four cases exceeding the acceptable limit of aquarium water (100,00/mL) and another four cases exceeding the limit of Coliform group (1,000 below/100 mL). As a result of investigating that we performed for 271 cases of water samples from coastal areas from April to November, we could detect 130 cases of vibrio species and 10 cases of Coliform group. After performing 17 kinds of antibiotic susceptibility test for 41 cases of isolated Vibrio parahaemolyticus, 27 cases showed tolerance to Amplicllin (AM), all of 31 cases showed intermediate resistance only to Cefazolin (CF) but had sensitivity to the rest of them. As a result of performing antibiotic susceptibility test, serum test and PFGE gene analysis on each 10 pair of Vibrio parahaemolyticus detected concurrently from intake-pipe water and, aquarium water, we couldn't get data showing that they are clearly same species in three kinds of test. In addition, UV sterilization, Ozonization and so on. Based on our research, intake pipe didn't have a problem with microbiological contamination so we are sure that the germ came from supplied fish had caused that kind of contamination. For effective management, UV sterilization or Ozonization which can be handled consistently should be adopted in aquarium.

가상수족관을 구성하는 요소들 중 어류 객체의 행동방식은 사용자의 시각적인 측면에서 가장 중요한 요소이다. 어류 객체의 개별 동작이나 행동뿐 아니라 객체의 속성을 통한 객체들 간의 상호작용은 가상세계의 역동성 및 사실성을 증대시킬 수 있다. 본 논문은 어류 객체들의 생명력, 이동량, 분포 가능한 최대 수심 및 식성 주기 등의 주요 습성들을 분석하고, 이에 따른 움직임과 다른 어류 객체들과의 상호작용, 평균 수명 데이터를 조정함으로써 해저 생태계의 균형을 시뮬레이션 하는 방법을 제안한다. 제안 방법은 어류 객체의 고유 속성값을 자유롭게 변경하여, 다양한 해저환경을 표현하는 가상수족관, 수족관 화면 보호기, 물고기 육성 게임 등에 활용되어질 수 있다.

The purpose of this study is to analyze the nutrition composition and physiological changes, and to evaluate the food quality of live fish in cultured and wild fishes which have been kept in an aquarium tank. The moisture and lipid content of wild and cultured fishes when kept in an aquarium tank for seven-days storage was found to be lower than those of the initial stage storage(zero day). The breaking strength was also rapidly decreased in all of live fishes tested in this study as the periods of storage extended. The protein content did not differ significantly. However, the content of cortisol, which is a indicator indicating a stress reaction in tissues, was apt to increasing as the periods of storage extended. The cortisol content of wild fishes were higher than those of cultured fishes. On the other hand, the activity of activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), which is also a indicator indicating a stress reaction, were not changed in the serum of wild and cultured fish, suggesting the ALT and AST activity dose not directly related with a healthy loss originated from stress. The death ratio of wild fishes were higher than cultured ones due to limited activity and stress during the storage in a aquarium tank.
