  • 본 연구에서는 멸종위기 야생생물 II급이자 천연기념물(453호)인 한국산 남생이 Mauremys reevesii가 집단으로 발견된 경북 경주시 내 저수지의 특성을 파악하였다. 또한 서식지 내에서 남생이의 생존에 직 간접으로 위협이 되는 생물 및 비생물적 요인들을 조사하였다. 남생이가 집단으로 발견된 지역은 농업용으로 관리 중인 저수지이다. 서식지 주변에는 수몰나무 지대, 석축, 산림, 갈대밭, 농경지(논)가 형성되어 있었다. 저수지 내 모든 남생이들은 저수지 북면에 형성되어 있는 수몰나무지에서만 발견되었다. 2018년 5월 10일과 8월 9일에 걸친 현지 조사에서 발견된 남생이의 수는 각각 28 개체와 21 개체였다. 남생이에게 위협이 되는 붉은귀거북과 황소개구리가 서식지 주변에서 다수 발견되었다. 문화재 발굴 작업, 화학 비료 그리고 생활 쓰레기가 저수지 곳곳에서 발견되었으며, 이는 남생이에게 큰 위협요인이 될 것으로 추정된다. 당해 연도 태어난 개체들은 확인되지 않았지만 아성체들이 다수 발견된 것을 고려하면 자연 번식이 충분히 이루어지고 있는 것으로 추정된다. 하지만 경쟁종인 붉은귀거북의 아성체 역시 발견되었기 때문에 남생이에게는 지속적인 문제가 될 수 있다. 연구의 결과를 종합하면, 국내 최대 규모의 남생이 개체군을 보호하기 위한 방법으로는 서식지 내 보전 방법이 적극적으로 고려되어야 할 것으로 판단된다.

  • Invasive species are organisms that are introduced into places outside of their natural distribution range. The global pet trade is facilitating the introduction of invasive species into new countries and areas. Among the introduced alien species, turtles are one of the most common animal groups whether lives in wetland ecosystems, such as wetlands or reservoirs. Like other countries around the world, exotic turtles is becoming a growing concern for the wetland ecosystem in South Korea. In this study, we report new reports of subspecies of Painted turtle (Chrysemysspp.): Chrysemys picta marginata, C. p. bellii and C. dorsalis, from the reservoirs in downtown Cheongju and Gwangju, South Korea. We used morphological features, such as the characteristics of the legs, plastron, and carapace, to identify the turtles. It is assumed that all turtles were artificially released into nature. Considering the increasing number of reports on the introduction of alien invasive turtles in Korean wetlands, we recommend the formulation of an immediate and systematic management plan for pet trades and organized continuous monitoring programs.

  • We conducted field surveys of amphibians and reptiles over a two-year period in 16 lagoons along the eastern coastline of South Korea, and determined the habitat characteristics correlated with the number of amphibian and reptilian species and individuals. We documented 11 amphibian species and 8 reptilian species. The dominant amphibian species was the black-spotted pond frog (Rana nigromaculata), and the dominant reptilian species was the red-eared turtle (Trachemys scripta elegans), an invasive species. Among the 14 habitat characteristics, connectivity to mountainous area significantly affected the number of amphibian and reptilian individuals. Other factors, including emerged plant cover, salinity, pH, the number of birds for amphibians and connectivity to agricultural land, lagoon perimeter length for reptiles also influenced the number of species or individuals of them. Our results demonstrate that these lagoons are home to more amphibians and reptiles than has been previously known. To effectively conserve herpetofauna in the lagoon ecosystem, lagoons as well as surrounding wetlands, grasslands, and mountainous areas should be protected.

  • Migratory birds, by crossing significant ecological barriers, carry and may subsequently introduce exotic seeds into new ecological zones during period of migration. The study of epizoochory, which includes seed dispersal by adhesion to bird feathers, has been relatively neglected compared to the study of seed dispersal by frugivores. To determine whether exotic seeds are being imported to stopover islands by migrating birds, and to estimate the quantity of seeds of exotic species being introduced, we examined migratory birds that were captured in mist nets for attached exotic plant diaspores in 2008 and 2009 on Hongdo Island, Korea. From a total of 3,947 birds examined, we found exotic seeds of Japanese Chaff Flowers (Achyranthes japonica) attached to three species of migratory birds (0.08%; Eurasian Bittern Botaurus stellaris, Swinhoe's Rail Coturnicops exquisitus and Oriental Turtle Dove Streptopelia orientalis). Despite the low occurrence of A. japonica seeds on the external parts of birds, the results suggest that migratory birds may be potential dispersing agents for A. japonica, a species that is currently threatening native ecosystems on many islands in Korea.

  • In this study, the pattern of texture was developed by applying the pattern shown in the Amita Yeoraebul and the Avalokitesvara with symbolism suitable for children's clothing. In addition, the design and the manufacturing of a children's wearable Hanbok were attempted, and the results are as follows: Amitha Yeoraebul is a Buddha who oversees paradise in Buddhism, and Avalokitesvara controls both paradise and the real world and provides mercy. Applying the various patterns in the Buddhist paintings, four daily hanboks for children were produced using patterns featuring symbolic the meanings of large round original patterns chrysanthemums, turtles, and lotus patterns. The lotus symbol represents love, nobility, and wealth, while the turtle symbol represents longevity, the chrysanthemum pattern symbolizes auspiciousness, and the large round original pattern means a constant continuation. To maintain the traditional hanbok form but allow convenient wear it in daily life, it is made in the jeogori + shorts, vest + long pants, and one-piece + jacket style. Currently, the daily dress of Hanbok and the modernization of traditional Korean clothes are being promoted. At this point, the study developed Hanbok fashion products that contain symbolic stories suitable for children are trying to maintain the image of traditional culture as much as possible.

  • This paper intends to improve caddies' vocational efficiency, to increase the quality of caddies' services for customers, and further, to widen the application of smart clothes by proposing prototypes of smart uniforms in which caddies' vocational characteristics are reflected. The smart uniforms proposed by this study were restricted to those for spring and fall seasons and three types for a jacket, a turtle neck shirt, pants, and a jumper were proposed. Each design was developed to contain functionality and aesthetic, and also to be transformed subject to weather or other conditions. In addition, the uniforms were designed to carry not only a two-way radio and a remote controller for a cart that caddies necessarily carry, but also i-Pod, a distance meter, and other digital tools by use of solar cells. That is, this paper proposed the designs that can meet with caddies' vocational characteristics and different conditions. This paper is regarded meaningful in that smart clothes, which are forecasted as a future high value-added business, are applied to the uniforms of various job types so they can expand me existing functions of uniforms and further, think about the ways of being used for higher value-added products through the fusion with technologies.
