김맹진,정상철,송춘복 한국어류학회 2004 韓國魚類學會誌 Vol.16 No.1

지하 해수나 저염분의 해수가 넙치(Paralichthys oliv-aceus)성장에 어떠한 영향을 주는지 알아보기 위해서 14주 동안 염분에 따른 넙치의 성장과 생존율을 조사하였다. 실험 조건은 5‰, 20‰, 35‰ 이며 실험어는 평균 체중 13.9±0.2g, 평균 전장 11.5±0.6 ㎝인 치어 240마리를 사용하였다. 실험 종결시, 전장과 체중의 성장은 35‰ 〉20‰ 〉5‰ 순으로 나타났으나 35 과 20 사이에서는 성장의 유의한 차이가 없었고(P〉0.05), 이들 염분과 5‰ 사이에서는 유의한 차이가 관찰되었다(P〉0.05). 그러나, 12주까지는 이들 염분조건 사이에 성장의 유의한 차이는 관찰되지 않았다(P〉0.05). 사료공급에 따른 사료섭식량은 35‰에서 가장 많았지만 염분간에 유의한 차이는 없었다(P〉0.05). 사료전환효율은 20‰에서 가장 높았지만 염분간 유의차는 없었다(P〉0.05). 생존율은 실험 후 14주까지 35‰에서는 97.5%, 20‰에서는 88.8%, 그리고 5‰ 에서는 86.2%를 나타내어서 5‰과 20‰ 염분에서 큰 차이를 보이지 않았다. 이러한 결과를 종합해보면, 20‰ 의 염분에서 사육된 넙치의 성장은 35‰ 의 일반해수의 결과와 유사하였으며, 일간성장률이나 먹이전환효율은 오히려 20‰ 의 염분 조건에서 높게 나타났다. 그리고, 5‰ 에서는 실험 종결시인 14주째에 약간의 성장 저하가 관찰되었으나(P〈0.05), 생존율은 20‰ 과 유사하게 나타났다. 따라서 제주도 넙치 양식 산업에서 다양한 목적으로 저염분 지하해수를 사용할 수 있을 것으로 생각된다. This experiment was conducted to learn the effects of salinity on growth and survival of juvenile olive flounder, Paralichthys oliuaceus. Fish were reared in completely recirculating fish tanks for 14 weeks. Six tanks (250 L/tank) were established with three different salinities (5,20 and 35‰), and thus a pair of tanks was assigned to each salinity. Water temperature was maintained at 20 to 22 C throughout this study. The results showed that growth of the fish was best at 35‰, less at 20‰, and least at 5‰. However, growth differences in total length and body weight of fish in 5, 20 and 35‰ were not statistically significant until the 12th week (P>0.05). Growth at 5‰ became significantly slower than at 20 or 35‰ on the 14th week(P<0.05). Although specific growth rate at 20‰ was slightly greater than at 35‰, the difference was not obvious (P> 0.05). However, significant differences in specific growth rate existed between 5 and 20‰, or 5‰ and 35%. When considering three food-related factors, such as condition factor (CF), feed intake, and food conversion rate (FCR), there were no meaningful differences among all salinities (P>0.05). At the end of this experiment, survival rate at 35‰ was 97.5%, and those at 20‰ and 5‰ were 88.8% and 86.2%, respectively. These results indicate that low salinity underground seawater is worth to be utilized for flounder farming industry in Jeju Island.

First record of Snyderina yamanokami (Pisces: Scorpaeniformes) from Korea

김맹진,황의욱,송춘복 한국수산과학회 2010 Fisheries and Aquatic Sciences Vol.13 No.3

This is the first report of Snyderina yamanokami, from the subfamily Tetraroginae of the family Scorpaenidae, collected in Korea. The specimen (175.3 mm long) was caught in the coastal waters of Jeju Island on a commercial longline hook on 9 September 2009. This species is characterized by the following morphological traits: 9-11 dorsal fin rays, 5-6 anal fin rays, 13-15 pectoral fin rays, 5 ventral fin rays, pectoral fin tip reaching or extending past the origin of the anal fin, palatines toothless, and four dark spots on the middle of the body. We suggest a new Korean name, “Keun-mi-yeok-chi,” for S. yamanokami.

Molecular Identification and Morphological Characteristics of the Longjaw Bonefish, Albula argentea Collected in Korea

김맹진,김병엽,송춘복 한국어류학회 2019 韓國魚類學會誌 Vol.31 No.4

One specimen of Albula argentea (296.3 mm in standard length), belonging to the family Albulidae, was collected in a set net in the coastal waters of Jejudo Island, Korea. As the adult A. argentea has not been caught from Korean waters, we described its morphological characters based on the collected specimen and compared them with those of the previous reports on A. argentea and A. koreaus. As a result, the present specimen was characterized by having 68~73 pored lateral line scales (vs. 77~78 for A. koreana), 72~73 vertebrae pored lateral line scales (vs. 77~80) and none streak on the check (vs. yellowish streak). Molecular analysis using the mitochondrial cytochrome b DNA sequences was also conducted to confirm the correctness of species identification and taxonomic status of the sample.

First Record of the Annular Sole, Brachirus annularis (Soleidae, Pleuronectiformes) from Korea

김맹진,고수진,윤병선,김성태,송춘복 한국어류학회 2019 韓國魚類學會誌 Vol.31 No.3

This is the first report of Brachirus annularis (Pleuronectiformes: Soleidae) from Korea. A specimen of B. annularis (229.0 mm standard length) was firstly collected by drift gill net at a fishing ground locating between Jejudo and Geomundo Islands, the southern coast of Korea on 31 March, 2019. This species was characterized by having five large, deep colored patches on the ocular side of body, each patch outlined by dark brown ring, united dorsal and anal fins jointed with caudal fin, and short pectoral fin. We add this species to the Korean fish fauna and propose its new Korean names, “Eol-luk-seo-dae-sok” and “Eol-luk-seo-dae” for the genus and species, respectively.

First Record of the Doublespotted Queenfish, Scomberoides lysan (Perciformes: Carangidae) from Korea

김맹진,김준상,송춘복 한국어류학회 2018 韓國魚類學會誌 Vol.30 No.4

This is the first report of Scomberoides lysan (Perciformes: Carangidae) from Korea. Two specimens (334 and 354 mm standard length) were collected by a set net from the coastal waters of Jejudo Island on 30 September, 2010. This species is characterized and distinguishable from a morphologically similar Scomberoides tol as follows. It has the posterior end of maxilla reaching to the posterior margin of eye (vs. not reaching in S. tol) and two rows of 5~8 small blotches on both sides of body (vs. one row of blotches). We add S. lysan to the Korean fish fauna and propose a new Korean name, “Du-jeom-jul-ga-si-jeon-gaeng-i” for the species because it has two series of dusk blotches on both sides of body.

김맹진 한국외식경영학회 2010 외식경영연구 Vol.13 No.4

The purpose of this research was to investigate the effect of consumer ethnocentric tendency and foreign culture acceptance on preference of traditional alcoholic beverage: Korean Makgeolli and Japanese Sake. Data were collected from undergraduate students and salaried men who have drinking experience in Seoul by trained interviewers. The result of the present study indicate that ethnocentric tendency was significant on the preference of Makgeolli and Sake.; positive on Makgeolli, negative on Sake. Foreign culture acceptance was not significant on the preference of Makgeolli, by contrast, significant on the preference of Sake; ineffective on Makgeolli, positive on Sake. This empirical study carries an important meaning to investigate the influence of consumers' ethnocentrism and foreign culture acceptance on the Korean and Japanese traditional alcoholic beverage.

The purpose of this study is to examine the effect of job training on job performance ability and organizational commitment in travel agencies. A survey for empirical research was conducted on travel agency employees who sell package travel products in the top 10 outbound transmission performances. 200 questionnaires were distributed and 171 questionnaires were collected. 158 questionnaires were used for the empirical analysis, except for the 13 questionnaires that responded unfairly. For the analysis of the questionnaire, frequency analysis for demographics, Cronbach's α for reliability verification, factor analysis for validity verification, and regression analysis for verifying the relationship between variables were performed using the SPSS 22.0 statistical program. Result of factor analysis, job training of travel agency consisted of lecturer ability, training contents, training environment, and job performance ability and organizational commitment consisted of single dimension. Result of the hypothesis test, lecturer ability, training contents, and training environment have a significant effect on the job performance ability. And the training contents, training environment have a significant effect on organizational commitment of employees. However, lecturer ability did not affect the organizational commitment of employees.

First Record of Epinephelus areolatus (Perciformes: Serranidae) from Korea

김맹진,송춘복 한국수산과학회 2010 Fisheries and Aquatic Sciences Vol.13 No.4

One specimen of Epinephelus areolatus, belonging to the subfamily Epinephelinae of the family Serranidae, was collected by a hook from commercial longline fisheries in the coastal waters of Jeju Island, Korea. This species is mostly similar to E. chlorostigma, but the former is distinguished from the latter by having larger brown spots and a white posterior margin on the caudal fin. We propose a new Korean name “Dae-moon-ba-ri” for E. areolatus.
