  • The purpose of this study was in search of native plant species showing metal-resistant property and excessively accumulating heavy metals in metal-contaminated soil or abandoned mines as well as in evaluation of applicability of phytoremediation. In the study area, species showing excessively accumulating heavy metals were a shepherd´s purse, pampas grass, a Korean lettuce, a Hwansam vine, the Korean persicary, a foxtail, a goosefoot, and a water pepper. The first screened plant species in Sambo mine were as shepherd's purse, Korean lettuce and pampas grass Among them the shepherd´s purse can be excluded because it is a seasonal plant and has lower removal capacity for heavy metals. The Korean lettuce was also excluded because of having lower removal capacity for heavy metals. Pampas grass is a highly bionic plant species constantly growing from spring. However it has weak points such as little accumulation capacity for zinc as well as small values of an accumulation factor and a translocation factor. Another problem is regarded as removal of roots after the clean up if pampas grass is applied to a farmland. In Sanyang mine, wormwood and Sorijaengi were considered as adaptable species.

  • This study was performed by questionnaire to investigate current use of native local foods of adults in Gyeongju classified by age. The subjects were consisted of 421 citizens(217 males and 204 females) living in Gyeongju. The findings are summarized as follows: 'Institute' scored high as 30.6% in the main responsible body for the succession of local foods. The most emphasized points to popularize the local foods was to 'taste'(36.4%). a point to be considered to develop tourism product of the local foods was to 'development of recipes acceptable to the people of today'(24.6%). The recognition rate score of native local foods of Gyeonngju area was 'Hwangnamppang', 'Hanjeongsik', 'Ssambap', 'Haejangguk', 'Hoe(Gampo)', 'Memilmukmuchim', 'Gyodongbeopju', and 'Yugoa' in the order. On the other hand, the recognition rate score for 'Ssukgulrei', 'Borisudan', 'Dalraikkakdugi', 'Hwanggeumju', 'Baesuk', 'Gyeojachae', 'Gungjungjeongol' was very low. The preferred and intake native local foods of Gyeongju area was 'Hanjeongsik', 'Ssambap', 'Hoe(Gampo)', 'Haejangguk', 'memilmukmuchim' in that other. On the other hand, the preference for 'Ssukgulrei' 'Borisudan', 'Hwanggeumju', 'Baesuk' and 'Dalraikkakdugi' was very low.

  • Moss is used as an important material in indoor landscaping as well as outdoor landscaping. Moss is vivid green during growth and excellent in ornamental value. But when temperature drops, moss stops growth, turns brown or loses its ornamental value. In the present experiment, for the purpose of classifying native mosses according to the growth response to low temperature, the temperature of the plant growth chamber was set to 15℃/5℃ (16h/8h, day/night) and 5℃ (24h) for 8 weeks using nine native moss species. Thereafter, the temperature of the plant growth chamber was set to 20℃, and then the changes of moss block area and moss color were measured. The changes of moss block area and moss color were measured using a Photoshop program, after each moss block was photographed. As a result, Atrichum undulatum (Hedw.). Beauv., Etodon luridus (Griff.) A. Jaeger, Bachythecium plumosum (Hedw.) Schimp, Plagiomnium cuspidatum (Hedw.) T.J. Kop, and Hypnum plumaeforme Wilson showed a small decrease in moss block area at low temperature, and their recovery were the fastest at 20℃. These three species had higher green values at low temperature compared to other species, and the greenness increased rapidly at 20℃. On the other hand, Atrichum undulatum (Hedw.). Beauv., Marchantia polymorpha L., and Thuidium cymbifolium (Mitt.) A. Jaeger showed the smallest block area at low temperature and the lowest recovery even at 20℃. Their green values also decreased significantly at low temperature, and maintained low green value even at 20℃. These results showed that these three moss species are sensitive to low temperature. The remaining Myuroclada maximowiczii, Plagiomnium cuspidatum, and H. erectiusculum showed moderate responses to low temperature compared to other six species of mosses.

  • 국내에서 수집된 인삼 자원 중에서 작물학적 특성이 우수하다고 조사된 54점(6~7년 근)을 대상으로 UPOV 조사 기준에 따라 주요 형태적인 특성들을 조사한 결과 경수는 1~4개 범위로 1개인 것이 42.6%이고, 2개인 것이 38.6%로 경수가 1~2개인 것이 전체 81.2%로 나타났으며, 경수가 5개인 것은 없었다. 장엽수는 3~6엽 범위로 5엽이 55.6%였고 4엽인 것은 25.9%였다. 경색은 자색계열이 전체 81.5%로 자색이 46.3%, 연자색이 25.9%를 차지하였다. 엽병색도 자색계열이 87%로 이 중 자색이 38.9%, 연자색은 29.6%를 차이 하였다. 잎의 주름 정도는 약간 있다가 20.4%였고, 46.3%가 강하다고 조사되었다. 잎의 거치정도는 없거나 약간 있다고 조사된 것이 51.9%였고, 29.6%가 강하다고 나타났다. 소엽모양은 넓은 타원형이 61.1%였으며, 타원형이 38.9%이였다. 풍기를 포함한 경북 지역 수집종 21점과 금산지역 수집종 29점 등을 포함한 54점의 수집종을 재료로 100개의 random primer를 이용 RAPD 분석 결과 OPA02 등 14개의 primer를 선발하였으며, 크게 금산지역과 풍기지역으로 group지워졌고, 풍기 수집종인 01-9, 01-35, 01-44는 금산지역으로 grouping되어진 반면, 금산지역 수집종 332001, 332002, 332003은 풍기 지역으로 grouping되었다. 금산지역 수집종은 65~86%로 변이가 심한 반면, 풍기지역 수집종은 73~95%사이로 금산지역 수집종의 혼계 정도가 더 심하였다. 특히 형태적 특성 면에서 두 지역간에 경수는 1~2개로 차이가 없었으나 장엽수, 경색, 엽병색, 소엽의 모양 등에서는 다소 차이를 보였다. 따라서 수집종의 유전 분석을 통해 선발된 OPA02, OPA07, OPC08, OPD11, OPD20 등 14개의 primer들은 앞으로 지역 재래종 특성 분류 등 인삼 유전자원의 특성 구분이나 품종개량에 유익하게 활용될 수 있을 것으로 사료된다.

  • 본 연구는 사건관련 fMRI를 이용하여 언어 내 및 언어 간 그림명명 과제를 수행하는 동안 모국어와 외래어 명사관련 피질 활성화 영역을 비교해 보고, 특히 외래어의 활성화 패턴이 모국어에 동조되는지를 알아보았다. 아울러 과제수행 언어가 정해지지 않은 임의적 언어전환 조건에 관여하는 활성화 영역도 연구대상이었다. 실험결과, 한 가지 수행언어만으로 제한되는 과제에서는 모국어 및 외래어 모두 좌측 하전두회(LIFG) 활성화가 일어났으나 모국어의 활성화 정도가 더 컸으며, 특히 외래어 명명 시 모국어와의 활성화 강도는 약화된 반면 영역분포는 유사한 결과를 얻었다. 이는 외래어가, 외국어가 아닌 모국어에 동조되었음을 시사한다 하겠다. 마지막으로 언어전환 조건에서의 실험에서는 좌측 하전두피질 외에 우측 중전두피 질이 관여함을 발견함으로써 실험수준이 아닌 일상수준의 다언어 사용에 있어, 의식이전의 언어 간 부호전환에 관여하는 우반구의 상대적인 기여와 역할을 시사하는 결과를 얻었다.

  • 화분의 수와 종류에 있어서 차이를 나타내며 K/Na 비율이 3.9-27.9 배로 토종꿀에서 증가한 반면, Fe, Zn, Al은 토종꿀에서 검출되지 않았다. 토종꿀과 양봉꿀은 각각의 구성성분에 있어서 미시적인 차이가 인정되었다. 토종꿀 특이적인 단백질의 전기영동적인 판별과 동시에 본 연구에서 확인한 화분의 종류, K/Na ratio, 및 Fe, Zn, Al의 검출여부 등으로 판별을 확증할 수 있으리라 기대되며 이와 같은 예비적인 특성 비교는 지역의 토종꿀의 고품질화를 위하여 필요하다고 판단된다.

  • This study was carried out to develop new varieties with early maturing and large fruit size in the Korean native dogwood (Cornus kousa) for woody landscape plants from native sites or cultivated area. The results are obtained as follows; We selected strains with early maturing and large fruit. size from the habitats from 2000 to 2003. ‘SKK 2-1’ had 4.0cm of fruit size while 2.0 cm of native variety. In addition, ‘SKK 2-2’, ‘SKK 2-3’, ‘SKK 2-4’, and ‘SKK 2-5’ with large fruit and early maturing were preliminary selected from the habitats. In the preliminary selections, ‘SKK 2-1’ was finally selected as new early maturing variety with large fruits in 2003. New early maturing variety with large fruit size, C. kousa var. ‘SKK 2-1’ was selected from 200 plants of 5-year-old seedlings in C. kousa in 5-12 Nung wean ri Goo sung myun Yong In, Kyung gi do, Korea in 2000. Their fruits were colorized in September 18, 20∼25 days earlier than October 7 of native varieties. Its fruit diameter is larger than 4cm. Its fruit weight was 5 times as heavy as native cultivars grown in Korea. This useful characters were still inherited after grafting. However, characteristics of growth, leaf, flower, and flowering period were not different from those of native varieties. Therefore, it was very promising landscape woody plant, having large fruits in early fall season. The rooting rate of Korean dogwood was high by the IBA treatment. The optimum date for softwood cutting was on June 25 ∼ July 25 when the rooting rate was more than 80%. In addition. Korean dogwood was easily propagated by grafting. Therefore, new early maturing variety with large fruits, C. kousa var. ‘SKK 2-1’ is easily propagated by softwood cutting or grafting and then is a promising cultivar as a woody landscape plant.
