  • This paper delineated the ecology including movement (departure from the rookery and returning to the rookery), egg-laying, and hatch of the penguins occurred in the cold years and a less cold year in the vicinity of King Sejong Station, King George Island off the Antarctic Peninsula. The years of 1988, 1991, 1992, and 1995 were selected as cold years and the year of 2001 was selected as a less cold year based on the mean annual temperature of the years. Gentoo Penguin (Pygoscelis papua) left their rookery in May, meanwhile some remained around the station. They returned in middle-September in the less cold .year, and returned in late-September to early-October in the cold years. Chinstrap Penguin (Pygoscelis antarctica) left their rookery in early-April in the cold years as well as in the less cold year without exception. They returned to the rookery in late-October to early-November in cold years, meanwhile in early-October in the less cold year. This difference in the returning of this bird seems to be related with the exposed sea water, i.e., sea ice condition to feed in the sea. The global warming will lead to the appearance of birds which breed in the Sub-Antarctic. For example, one pair of King Penguin (Aptenodytes patagonicus) was observed in the Maxwell Bay in austral summer. And a pair of snide-like bird was recently observed for the first time in November 2001 at the penguin rookery located in the Barton Peninsula, King George Island. And it will also lead to the disappearance of an Emperor Penguin (Aptenodytes forsteri) which appeared in the full winter when Maxwell Bay and Marian Cove were frozen. It seems that the behaviour of the penguins observed around the station shows the complex effects of the ecology of the birds in combination with the natural environments, which include feeding strategy and areas, animal Instincts, exposed terrain related to weather conditions, and globa1 warming. It is necessary to take further observation and carry out systematic researches on the birds including penguins around the station which show the ecology of the birds as well as the environmental changes.

  • Plasmodium spp. in domestic and wild birds are microscopic, intracellular parasitic protozoa within the blood cells and tissues cause avian malaria. A 17-month-old Magellan penguin (Spheniscus magellanicus) with a clinical signs of anorexia, depression, and respiratory distress for 3 days was submitted to the Pathology Department of Veterinary Medicine, Cheju National University in October 2005. It was born and reared in the Jeju Island. Grossly, the liver was enlarged, pale and friable. The spleen was also enlarged with dark red coloration and friable. Histopathologically, the lesions in the liver were characterized by multifocal infiltration of macrophages and lymphocytes especially in perivascular regions. The schizonts of Plasmodium spp. contained up to 30 merozoites were found in numerous infiltrated mononuclear cells. Similarly, histiocytic cells were proliferated in red pulp of spleen and the schizonts were found in these cells. Numerous dark brown pigments were widely distributed in the liver and spleen. The result of the nested polymerase chain reaction clarified the causative agent of this case was Plasmodium spp.. This is the first report for the outbreak of avian malaria caused by Plasmodium spp. in a penguin that was born and reared in Jeju Island in Korea.

  • A female, 14-year-old, African penguin (Spheniscus demersus) weighing 2.5 kg with the anorexia for one day and 22 months history of bumblefoot was found dead in aquarium. Grossly, severe bumblefoot in the central surface of the right foot, severe enlarged liver and kidneys with orange color were observed. Histopathologically, pinkish amorphous materials were accumulated in liver, spleen, kidney, and stomach. The pinkish materials in the liver, kidney, spleen, and stomach were confirmed as amyloid with typical orange color reactions using Congo red stain under the light microscope and with bright red color expressions using Congo red stain under the fluorescence microscope. Based on the typical gross and histopathologic findings and special staining, this case was confirmed as systemic amyloidosis. A long period time of moderate bumblefoot might be closely associated with the occurrence of systemic amyloidosis in the captive penguin.

  • A three years old male Jackass penguin(Spheniscus demersus) showed anorexia, depression, respiratory problem for a few days, followed by clinical treatment for 20 days resulted in death. Grossly, multiple white nodules measuring 2~3 mm in diameter were observed in the surface of and inside lung, liver, kidney, thoracic wall. Microscopically, granuloma formations were observed in the lung and liver. The margin of granuloma surrounded by connective tissue barrier and infiltrated lymphocytes, and also observed giant cell near the granuloma. By Periodic acid Schiff reaction, hyphae were detected in granuloma of lung and liver. This case was a chronic and systemic aspergillosis caused by Aspergillus fumigatus infection in a Jackass penguin at a zoo.

  • This study applied a metagenomic analysis of the penguins' gut microbiome from fecal samples of Adélie Penguin (Pygoscelis adeliae) and Emperor Penguin (Aptenodytes forsteri) living along the Ross Sea, Antarctica. As a result of taxonomic analysis, 7 phyla and 18 families were mainly present in the gut microbiome of Adélie and Emperor penguins. To assess microbial diversity, we performed alpha diversity and OTU abundance analyses. It was confirmed that the Adélie Penguin's gut microbial species had a higher diversity than Emperor Penguin's. Based on the Beta diversity analysis using PCoA, differences were observed in the clustering between Adélie and Emperor penguins, respectively. Through the KEGG pathway analysis using PICRUSt, the nucleoside and nucleotide biosynthesis pathway was the most prevalent in Adélie and Emperor penguins. This study enabled a comparison and analysis of the composition and diversity of the gut microbiome in Adélie and Emperor Penguins. It could be utilized for future research related to penguin feeding habits and could serve as a foundation for analyzing the gut microbiomes of various other Antarctic organisms.

  • This study was designed to investigate and analyze children's preference on animation characters according to age and gender of the subjects, by surveying 255 children aged from 3 to 5. The animation characters were represented in pictures, and the reasons of preference were collected through individual interview with the children. The $x^2$ verification of SPSS 18.0 Window statistic program was used to verify the difference in preference. As a result, children aged from 3 to 5 showed higher preference on animations produced in foreign countries than the ones produced in Korea, as Korean animations and foreign-country animations had preference rate of 35.7% and 64.3%, and Korean characters and foreign-country characters had preference rate of 22.4% and 77.6% respectively. Depending on the age of children, there was significant difference among animation characters that the children prefer ($x^2=302.474^{***}$, P<.001), and it was shown that children at the age of 3 showed preference on 'Pororo' of Pororo the Little Penguin, children at the age of 4 on 'Tayo' of Tayo the Little Bus and 'Amu' of Shugo Chara, and children at the age of 5 on 'Shin Chan' of Crayon Shin Chan. It was also revealed that there was significant difference among animation characters according to the gender of children ($x^2=120.864^{***}$, P<.001); boys preferred 'Pororo' of Pororo the Little Penguin the most, followed by 'Doraemon' of Doraemon, 'Thomas' of Thomas and Friends and 'Tayo' of Tayo the Little Bus, and girls preferred 'Pororo' of Pororo the Little Penguin the most, followed by 'Apple' of Little Princess, 'Amu' of Shugo Chara and 'Loopy' of Pororo the Little Penguin. Through this study, it is hoped that the development of children animation would advance further, and that this study could be used as the preliminary resource.

  • Penguins are one of the key constituent organisms in the Antarctic ecosystem. A total of 18 species of penguins occur only in the southern hemisphere from the Galapagos Archipelago to southern area off Australia and New Zealand, South Africa, South America, and the islands scattered in the Southern Ocean to the coast along the Antarctic Continent. In the Antarctic Treaty area, there are only 5 species of penguins such as Emperor (Aptenodytes forsteri), Gentoo (Pygoscelis papua ellsworthi), Adelie (P. adeliae), Chinstrap (p. antarctica), and Macaroni (Eudyptes chrysolophus) penguins. Two additional species, the King (Aptenodytes patagonicus patagonicus) and Rockhopper (Eudyptes chrysocome) penguins, however, are distributed within the Antarctic Convergence. In the vicinity of king Sejong Station located in King George Island, the South Shetland Islands off the Antarctic Peninsula, 5 species are observed, among which 2 Pygoscelis species such as the Gentoo and Chinstrap penguins hatch their eggs and raise their chicks at the rookery 2km south offing Sejong Station in summer. Adelie penguins hatch their chicks in other place in King George Island. One Emperor penguin roamed on the frozen Maxwell Bay which has been frozen every two or three years with the approximate thickness of 60cm. And one Macaroni penguin also visited the rookery in summer. We should carry out researches on the penguins occurring in the vicinity of King Sejong Station to monitor the environmental changes around King Sejong Station and the South Shetland Islands.
