Odontobutis platycephala were caught at Bosung River, Jeollanam-do and morphological development of eggs, larvae, and juvenile investigated in the laboratory at Chonnam National University. Fertilized eggs were oval in shape, demersal, and adhesive. The length of the fertilized eggs were 4.77~5.22 ㎜ of the major axis and 1.93~2.26 ㎜ of the minor axis. The first hatching was occurred in 428 hours 6 minutes after fertilization in water temperature 18.0~20.0℃. Newly hatched larvae attained mean 5.23 ㎜ in total length(TL), and the caudal notochord was flexed 45° upward. On the 15 days after hatching, the larvae attained mean 5.94 ㎜ in TL and had a dorsal fin and anal fin. On the 20 days after hatching, the larvae attained mean 7.53 ㎜ in TL and the feeding activity became active. On the 29 days after hatching, the larvae attained mean 8.21 ㎜ in TL and reached the juvenile stage.

한경호,황동식 한국어류학회 2003 韓國魚類學會誌 Vol.15 No.1

본 연구는 2001년 5월부터 10월에 광양만, 가막만 및 여수시 돌산도 연안에서 채집한 Scartella cristata의 발육단계에 따른 자치어의 형태를 관찰하였다. 채집돈 Scartella cristata 자치어는 총 235개체로 주로 7월과 8월에 각각 78개체, 93개체가 채집되어 가장 많았고, 체장범위는 2.53~15.85㎜였다. 본 종의 자치어들은 몸의 형태, 체형, 계수형질 및 흑색소포의 분포 상태가 Okiyama(1998)가 보고한 Scartella cristat의 결과와 일치하였다. Scartella cristata는 한국 미기록 어종으로 머리부분에 여러갈래의 피질돌기가 갈기 모양으로 형성되어 있는 특징에 근거하여 “갈기베도라치”로 국명을 신칭하였다. 평균 체장 2.57㎜의 자어는 난황이 완전하게 흡수되어 있고, 근절은 28~30개였다. 평균 체장 5.95㎜ 이상의 개체에서 완전하게 위로 굽어져 있었다. 평균 체장 10.50㎜ 전후의 개체들은 모든 지느러미 줄기가 정수에 달하여 치어기가 이행하였고, 평균체장 12.20㎜ 치어들은 코 부분과 눈 윗부분에 갈기모양의 피질돌기가 형성되기 시작하였다. The development of larvae and juveniles of the blenniid fish, Scartella cristata were studied based on the specimens collected in coastal waters of Yosu, Korea from May to October, 2001. 235 individuals of the species were collected during the study, which were 2.53-15.85㎜ in standard length. Body form, meristic characters and distribution of melanophores coincided with those of Scartella cristata described by Okiyama (1988), which was not revealed from Korean. Therefore, we proposed it's new Korean name as "Gal-gi-be-do-ra-chi". Yolk was completely absorbed when the larvae was about 2.57 mm in average standard length (ASL), with 28-30 myomeres. Flexion of the notochord started when the postlarvae was about 5.12 ㎜ in ASL and finished about 5.95 mm in ASL, respectively. The larvae had reached at the juvenile stage when 10.50㎜ in ASL and all the fins were completed. The cirri and fleshy crests were begun to appear on the snout and upper region of eye respectively when 12.20㎜ in ASL.

한경호,오성현,황동식,조영현,서대철 한국어류학회 2002 韓國魚類學會誌 Vol.14 No.2

본 연구는 2000년 8월 19일 전라남도 신안군 임자도 연안에서 2각망으로 어획된 민어 어미를 인위적인 방법으로 수정하여 부화 사육하면서 관찰한 卵發生 過程 및 仔稚魚 형태변화는 다음과 같다. 1. 민어의 受精卵은 구형의 분리 부성난으로 알의 크기는 0.96~1.08㎜(평균 1.01㎜, n=50)였고, 크고 작은 油球가 1~5개(0.06~0.34㎜) 존재하였다. 2. 사육수온 25.2~28.4℃에서 受精 후 17시간 10분에는 배체가 卵膜을 뚫고 머리부터 孵化하기 시작하였다. 3. 孵化 직후 仔魚의 전장은 2.36~2.63㎜(평균 2.48㎜, n=10)로 전장의 45.0~47.0%에 달하는 큰 卵黃(장경 1.11~1.20㎜, 단경 0.92~0.96㎜)을 가지고 있으며 筋節은 7~8+ 17~19=24~27개였다. 4. 孵化 후 3일째 仔魚는 전장 3.98~4.32㎜(평균 4.16㎜, n=10)로 입은 열려있었고, 이 시기에 섭이활동이 활발하게 관찰되면서 卵黃이 완전히 흡수되어 後期仔魚期로 이행되었다. 5. 孵化 후 10일째 後期仔魚는 전장이 5.88~6.74㎜(평균 6.30㎜, n=10)로 꼬리의 말단이 굽어지기 시작하는 시기로 黑色素胞가 기저후두골 뒷부분의 체측에서 점모양 및 나뭇가지모양 으로 출현하였다. 6. 孵化 후 31일째 개체의 전장은 9.62~12.76㎜(평균 11.12㎜, n=10)로 모든 지느러미가 정수에 달하였고, 체형이나 반문이 成魚와 닮아 種魚期로 이행하였다. Egg development and morphological change of larvae of the brown croaker, Miichthys miiuy, were investigated after obtaining samples by artificial insemination. The spawning season extends from the middle to the end of August in the seas off Lim-ja Island, Cheollanam-do. The fertilized eggs were transparent, spherical, separate and they floated. Egg diameter ranged 0.96~1.08㎜ with several oil globules of 0.06~0.34㎜. Hatching occurred 17 hours 10 minutes after fertilization in 25.2~28.4℃ water temperature. The newly-hatched larvae were 2.36~2.63㎜(mean:2.48㎜, n=10) in total length(TL), had a large yolk, and 7~8+17~19=24~27 myotomes. Melanophores were distributed on the eye lens. Three days after hatching the larvae had attained 3.98~4.32㎜ in TL(mean:4.16㎜, n=10), the yolk sac was completely absorbed, and they had transformed into the postlarva stage. The larva reached the juvenile stage with all fins formed and with a complete set of fin rays(D.Ⅹ-28~31;A.Ⅱ-7~8;P. 21~23;C. 19~21;V. 25~26) on the 31st day after hatching. The juveniles were 9.62~12.76㎜(mean:11.12㎜, n=10) in total length. At this point the juvenile was similar to the adult in body form and pigmentation pattern.

Fishes were collected by trammel net to determine seasonal species composition and biomass in coastal waters of Seokbyeong, Pohang, Gyeongsangbuk-do from January to December, 1998. A total of 607 fishes(93,427g) was sampled and classified into 58 species belonging to 27 families and 7 orders. The most dominant orders were Scorpaeniformes and Perciformes, which together accounted for 70.7% of the total. The most dominant family Scorpaenidae was represented by eight species. The dominant species were Ditrema temmincki, Hexagrammos agrammus, H. otakii, Halichoeres poecilopterus, Stephanolepis cirrhifer, Sebastes inermis, Sebastes pachycephalus, Engraulis japonicus and Pleurogrammus azonus; they accounted for 62.9% of the total fishes collected. The dominant species in biomass were Ditrema temmincki, Hexagrammos agrammus, H. otakii, Halichoeres poecilopterus, Sebastes inermis and Pleurogrammus azonus. Those species accounted for 58.4% of the total biomass. The number of individuals and the biomass were much higher in summer and autumn than in winter and spring, and closely correlated with water temperature. Monthly number of species was highest in May, with 24 species and lowest in January, with 10 species. The highest diversity index was in June(H'=2.594), and lowest in January(H'=1.640). The diversity index was 1.640~2.594, with little monthly fluctuation. The diversity index in coastal waters of Seokbyeong was higher than that in other coastal waters. It suggest that the cluster structure may be stable.

With the era of big data, the big data has been expected to have a large impact in the NPP safety areas. Although high interests of the big data for the NPP safety, only a limited researches concerning this issue are revealed. Especially, researches on the logical/physical structure and systematic design methods for the big data platform for the NPP safety were not dealt with. In this research, we design a new big data pilot platform for the NPP safety especially focusing on health monitoring and early warning services. For this, we propose a tailored design process based on SE approaches to manage inherent high complexities of the platform design. The proposed design process is consist of several steps from elicitate stakeholders to integration test via define operational concept and scenarios, and system requirements, design a conceptual functional architecture, select alternative physical modules for the derived functions and assess the applicability of the alternative modules, design a conceptual physical architecture, implement and integrate the physical modules. From the design process, this paper covers until the conceptual physical architecture design. In the following paper, the rest of the design process and results of the field test will be shown.

한경호,이성훈,조재권,황동식,유동재 한국어류학회 2001 韓國魚類學會誌 Vol.13 No.3

Spawning behavior of the Takifugu pardarlis(Temminck et Schlegel) was observed on the Jook-do coast in Tongyong from March 1997 to June 1999. The spawning ground was locted in the intertidal zone between Tongyong and Koje-do. Its bottom was mainly gravels and stones, and its depth was 0.5∼1.0m. Spawning season was from the end of the March to the middle of May. During the spawning season, the mature fishes formed school a of 10∼30 individuals, then moved to the spawning ground together. When a mature female spawned eggs, the attendant males fertilized them at the same time. The fertilized eggs obtained from the parent fishes caught at the spawning ground were adhesive, opaque and spherical, measuring 1.14∼1.24㎜ (mean 1.19㎜, n=50) in diameter with numerous tiny oil globules. Hatching period was about 205 hours after fertilization at water temperature of 18.0±0.5℃. The newly hatched larvae were 2.92∼3.10㎜ (mean 3.01㎜, n=20) in total length (TL), had a large yolk, and 11∼13+14∼15=25∼28 myomeres. At 5 days, the larvae had attained 3.79∼3.85㎜ (mean 3.82㎜, n=20) in TL and had transformed into the postlarval stage. At 15 days, the postlarvae had attained 7.78∼7.90㎜ (mean 7.84㎜, n=20) in TL. At 21 days, had larvae attained 10.15∼10.27㎜ (mean 10.21㎜, n=20) in TL and had reached the juvenile stage. All fins were formed with a complete set of fin rays having the following counts: dorsal fin rays 11∼12; anal fin rays 9; pectoral fin rays 14∼15; caudal fin rays 11∼12.

The egg development and morphological development of larvae and juveniles of crucian carp, Carassius auratus (Linnaeus) caught at Bosung River, Chollanam-do, in April to June, 1999 were investigated in the laboratory, Yosu National University. In the spawning season, the nuptial organ was appeared on the opercular region and under region of eye, pectoral fin, ventral fin and lateral line. The egg was transparent of yellowish brown color, demersal of adhesive and sperical in shape, measuring 1.49∼1.63㎜ (mean 1.57㎜, n=50) in diameter. The first hatching was occured in 75 hours 10 minutes after fertilization in water temperature 18.3∼21.7℃. Newly hatched larvae attained mean 4.28㎜ had a big yolk sac and their mouth, and anus were not opened yet. At 5 days after hatching, the larvae attained mean 5.34㎜ and the yolk sac was almost absorded. At 13 days after hatching, the larvae attained mean 7.21㎜. The caudal notocord was flexed 45°upward, and they reached post larvae stage. At 31 days after hatching, the larvae, mean 14.68㎜ in TL reached the juvenile stage with all of the fins formed with complete set of the fin rays (D. ⅩII-11∼15; A. Ⅲ-5∼6; P. 15∼16; V. 1-8).
