  • The fish species Uraspis helvola and U. uraspis (family Carangidae, Perciformes) were collected from Korea, and described and compared based on morphological and molecular characters. Uraspis helvola and U. uraspis were clearly distinguished by differences in the beginning point of the straight lateral lines scales (dorsal fin soft rays 12th~13th in U. helvola vs. 15th~16th in U. uraspis), and in the naked area on the breast extends to the pectoral fin base (naked area half way in U. helvola vs. naked area widely connected in U. uraspis). Molecular analysis using 530 base-pairs of mitochondrial DNA cytochrome c oxidase subunit I gene strongly supported the morphological identification. We described it as the new Korean record, and proposed the new Korean name "min-jeon-gaeng-i-sok" for the genus Uraspis, and "heuk-gi-min-jeon-gaeng-i" for the species U. uraspis.

  • Even though the animation industry has been growth since 2011, there is still imitation by public stereotype which insists that animation is only able to cover the young age group and is not the proper genre of art to convey a social or a philosophical agenda. However, describes the philosophical agenda of 'social class' and 'life and death' in the limited space by expressing characteristics and background of fish through its own way. Thus, it shows how animation goes beyond aforementioned limits. Straying from traditional happy-ending, it criticizes present social problems by telling despite fishes' effort they cannot escape from structural contradictions. The drawing technique in musical expresses the character's ideology and attitude to make people think about how we will behave in the face of life and death. Therefore the purpose of this paper is analyzing director Lee Dae-hee's animation and present the genre expandability of animation.

  • To investigate the materials in the preparation of kimchi for Koreans in the Commonwealth of Independent States(CIS) a survey was completed by 199 Koreans living in Moscow, Sahalin, Uzbekistan and Jazahstan, In the way to purvey the materials of Kimchi, the frequency to get all the materials of Kimchi in the markets is 74.7% on the whole and by regional groups the frequency is relatively high in Moscow and Kazahstan, For the main ingredients most respondents use Chinese cabbage, cabbage, or turnips. In general Chinese cabbage is used most, But the respondents who live in Moxcow and Kazahstan. For the main ingredients most respondents use Chinese cabbage, cabbage, or turnips. In general Chinese cabbage is used most, But the respondents who live in Moscow and Kazahstan. 쫴 are younger, or belong to higher emigrant generation, prefer cabbage kimchi. For the additional vegetables many respondents use carrots. For the seasonings, garlic, red pepper powder, and salt are added to Kimchi, but the use of ginger, whole seasame seed, and waxy rice paste is relatively low. The coriander, which is not added to kimchi in Korea, is used in Kimchi By above 80% of the respondents living in the three regions except Sahalin. It is considered to be due to the effect of the western dining cultural area. For the animal materials, 74.4% of the respondents add lightly salted fish to Kimchi and all toe respondents in Sahalin add salt-fermented sea food, the kind of which is mainly salt-fermented croaker. The reasons given for not adding salt-fermented seafood to Kimchi in the three regions except Sahalin, 59.9% of the respondents said it was because of the difficulty to purvey, 21.1% because of the fishy taste, and 16.8% because of not considering the addition of self-fermented sea food in Kimchi. The higher the emigrant generation of respondents, the less seasonings of strong flavor like garlic, red pepper powder, and salt-fermented sea food are used, and the more coriander is used. In the salting of Kimchi preparation, 97.8% of the respondents salt the main vegetables by soaking in brine and its concentration is controlled by experience.

  • Yellowtail Seriola quinqueradiata tagged with a Pop-up Satellite Archival Tag (PSAT) was released off the coast of near the Moseulpo, Jeju Island and the ecological data during about 40 days was obtained. However, it is difficult to determine the spatial location of underwater ecological data. To improve the accuracy of estimating the Yellowtail migration route using temperature, suitable background field of the oceanic environment data was evaluated and used for input data. After developing of the tracking algorithm for migration route estimation, three experiment cases were estimated with ecological data among the surface layer, the mixed layer, and the whole water column. All tracking experiments move from western to eastern Jeju Island. Additionally, tracking experiment using 3D ocean numerical model reveal that it is possible to estimate the migration route using the fish ecological data of the entire water column. Therefore, using a large number of ecological data and a high-accuracy ocean numerical model to estimate the migration route seems to be a way to increase the accuracy of the tracking experiment. Moreover, the tracking algorithm of this study can be applied to small pelagic fishery using small archival electronic tags to track the migration route.
