  • We surveyed the distribution of exotic weeds in Korean paddy fields, uplands, orchards and pastures from 12,568 sites during 3 years, 2013, 2014 and 2015. As a result, 166 species in 28 families were identified and 7, 130, 126, and 80 species were surveyed from paddy fields, uplands, orchards, and pastures, respectively. Among the 166 species, 128 species were annual weed and 38 species were perennial weed. Especially, winter annual exotic weeds were 63 species (37.8%). 46, 16, and 104 exotic weeds were classified to their introduction period of $1^{st}$ (1876-1921), $2^{nd}$ (1922-1963), and $3^{rd}$ (1964-now) period, respectively. The exotic weeds introduced in $2^{nd}$ and $3^{rd}$ period, included 12 Invasive Alien Species. The weeds from $1^{st}$ period, however, could be grouped into native weeds as the 'naturalized weed' and managed the same as the native weeds. Especially, some exotic weeds such as common groundsel were widely distributed in Korean crop lands, and they will become more problematic in near future. Therefore, systemic research from the biology to management should be conducted and the results from the studies should be applied practically.

  • The exotic ox-warble fly, Hypoderma bovis has been established its life cycle at the high mountain region on the middle part of Korea. Milk cattle and Korean cattle of S pasture, H pasture and farms were infested with the third stage larva of the flies. Infection rates were 54.5% in S pasture and 30.4% in H pasture or farms. The second or third stage larve were detected from the back side of cattle and the muscle around epidual fat at autopsy. The grubs of ox-warble fly were throughly identified as Hypoderma bovis by the characteristics of spines or tubercles on the segments and stiginal plates.

  • Presenting desirable direction of Korean interior landscape, the present studies were performed to survey the status of interior landscape of the Korean traditional and modern house in order to compare each other about the landscaping characteristics. The results were as follows: 1. Interior landscape of traditional houses put emphasis on mental aspects through furnitures, decorative elements, symbolic signs, paintings, writings, and moderate plants. 2. Interior landscape of modern house accentuated visual beauty by using westernized furnitures and decorative elements, and exotic plants. 3. These days we abundantly use exotic interior plants, but we need to develop native plant materials which have visual values and are well grown. 4. It is suggested that we should make effects to find and develop Korean interior landscape style which succeed from traditional interior landscape that has more accentuated on mental aspect.

  • This study was carried out to survey the fauna of some parks around Kunsan-city and to establish biological impact on the development of those parks. Among the fauna surveyed, insects consist of 74 species in 49 families and 13 orders. The insect fauna was poor, because the environment was made of simple flora and mostly farmland. Fish in the reservoir of Wolmyong-Park consist of 7 species. Among them, Ctenopharyngodon idellus is an exotic species and characterized with its voracious plantfeeding. This fish severely destroyed the habitats and spawning sites of other sympatric fish. For the conservation of non-exotic fish, birds, and mammals in the area, the integrated biological direction would be needed.

  • This study found through that Fortuny's art world with design aesthetics was devided into historicism, purism, exoticism and mysticism of color. \circled1 Fortuny's aesthetic observation dazzled at that time and he apply well-grounded opinion in historicism of his all creation and then accomplish on the whole mysticism of art and technique dwelled creativity, \circled2 Fortuny's Delphos gown realized new creation of beauty intact by that the simplicity and contingency was inquired into the art at that time. He revived that aesthetic was included in the drapery of ancient Greece, so indirectly express outline of the human body and realized pure image used a natural curved line of the human body. \circled3 Fortuny's creations included a exotic special quality. His clothes expected so many characteristics of 20C fashion and exotic, visionary fashion revolution in addition influenced on stage costume. ㉧ Fortune created new color specially "Tempera" and expressed mysticism of color that found a harmonious color character and texture through the ancient techniques included experimental mind of a multilateral try.teral try.

  • Feed conversion efficiency contributes directly or indirectly on the cost benefit ratio of silkworm rearing and is considered to be an important physiological criterion for evaluating the superiority of silkworm breeds/hybrids. Food intake, assimilation and conversion of indigenous as well as exotic silkworm races are well studied by many researchers. In this review, an attempt has been made to consolidate works on feed conversion aspects of indigenous and exotic silkworm races. The paper also deals with the effect of various factors viz., nutritional, environmental and feeding on food assimilation and conversion parameters of mulberry silkworm.
