도라지, 콩 등 작물뿐만 아니라 도로변의 코스모스 등의 화훼류에도 피해를 준다. 발생된 포기를 직접 손으로 제거하고 불로 태우는 것이 확실하나 발생면적이 넓을 경우에는 밭작물에 등록된 토양처리형 제초제로 방제한다.

Top parts of $Dendranthema$ $zawaskii$ var. $yezoense$ (DZY) and $Cosmos$ $bipinnatus$ (CB) are believed to contain substances with antioxidant effects and activity. Present experiments were undertaken to investigate an adequate and efficient extraction method which ensures the highest yield of antioxidant components. Extraction yield was 1.11-1.92 times higher by ultrasonic method than other methods in both species. By 45 minute ultrasonic extraction, total polyphenol contents reached the highest level, $80.70mg{\cdot}g^{-1}$ tannic acid equiv./DW in $Cosmos$ $bipinnatus$ and total flavonoid contents $50.41mg{\cdot}g^{-1}$ naringin equiv./DW in DZY. DPPH radical scavenging activity was almost the same among extraction methods or slightly higher in reflux extraction. The highest DPPH radical scavenging was observed by reflux extract in CB ($RC_{50}=0.135mg{\cdot}mL^{-1}$). ABTS radical scavenging activity was the highest by 15 minute ultrasonic wave in DZY and CB, $RC_{50}=0.159mg{\cdot}mL^{-1}$ and $RC_{50}=0.139mg{\cdot}mL^{-1}$, respectively. High ferrous ion chelating effects were obtained by 30-minute ultrasonic wave in DZY ($RC_{50}=0.803mg{\cdot}mL^{-1}$). Extracts of top parts of DZY obtained by reflux method showed the highest inhibition effect against peroxidation of linoleic acid, and extract of CB obtained by ultrasonic for 45 minutes showed the highest inhibition effect. In conclusion, optimum extraction method should be adjusted according to plant species and antioxidant substances.

Landscape crops have decorated its surrounding landscape by being cultivated from spring to late fall. Recently, landscape crops are starting to get the limelight as crops that can be cultivated in large area farmlands. Therefore, we examined the growth characteristics of landscape crops, green manure yield and nitrogen production of crops that are cultivated during summer, which are sunflower, cosmos, sunnhemp and sesbania, in order to select crops that can be utilized as landscape crops and green manure crops. The height of landscape crops increased when the harvest time was later. Especially, sunnhemp, cosmos, sunflower and sorghum grew over 100cm. The days to flowering of sunnhemp and cosmos were 50 and 53 days each, and their flowering period of more than 50 days were long. The days to flowering of sunflower, which was 52 days, was short, and its flowering period, which was 21 days, was also short. When the harvest time was later, the green manure yield and nitrogen production of all crops increased. Individually, the green manure yield was higher in sunnhemp, sorghum, sunflower, with $7.2{\sim}7.5Mg\;ha^{-1}$, and was lowest in sesbania. The nitrogen production was higher in sunnhemp, with $168.1kg\;ha^{-1}$ Therefore, as seen in its flowering characteristics, green manure yield and nitrogen production, sunnhemp had the best green manure and landscape effects among the landscape crops for summer.

The flowers of Cosmos bipinnatus were extracted with solvent made with methanol:water (4:1) and the concentrates were partitioned into ethyl acetate (EtOAc), n-butanol (n-BuOH), and water (H₂O) fractions. The octadecyl silica gel (ODS) and silica gel (SiO₂) column chromatographies were repeated for the EtOAc fraction to isolated of two phenolic compounds. The chemical structure of the isolated compounds were identified as benzyl O-β-ᴅ-glucopyranoside (1), and 2-phenylethyl O-β-ᴅ-glucopyranoside (2) through spectroscopic datas such as nuclear magnetic resornance, infrarad spectroscopy, and mass spectroscopy. These two compounds were first isolated from C. bipinnatus flowers through this study. To evaluate the anti-atopic activity of the two isolated compounds using a HaCaT cell line induced by ultraviolet light, several experiments were conducted and neither both compounds showed toxicity in the concentration range of 1 to 1,000 ㎍/mL. In the results of anti-atopic activity through Thymus and activation regualted chemokine (TARC) assay, both compounds showed dose-dependent TARC inhibitory activity. In particular, compound 1 showed significant activity even in a low concentration range of 10 ㎍/mL, and in different concentration ranges. Also compound 1 showed higher inhibitory activity than other compound, confirming that the anti-atopic activity was the most excellent. Based on these results, it is considered that it can be used as a functional cosmetic material.

This study investigated the flora and the main vegetation of naturalized plants in order to compare the change of distribution in Limja Island, South Korea from 1999 to July, 2005. Flora of naturalized plants in surveyed site were the 1st survey 1999 year, 14 families 45 taxa, the 2nd survey 2005 year, total 14 families 54 taxa including 53 species 1 variety. which new 9 taxa included as Eragrostis curvula, Festuca myuros, Panicum dichotomiflorum, Atriplex hastata, Abutilon avicennae, Aster subulatus, Coreopsis lanceolata, Cosmos sulphureus, Cerastium glomeratum, etc. By the community table, the main vegetation communities in the surveyed sites were classified as Phytolacca americana, Rumux crispus, Bromus catharticus, Erigeron annuus - Erigeron canadensis, Oenothera odorata, Paspalum distichum, Festuca myuros, Cosmos sulphureus community. it is believed that the species of naturalized plants have increased compared to other areas due to their close location to the living habitation.

빅 히스토리(거대사)는 빅뱅부터 생명과 인류의 등장, 그리고 문명에 이르기까지 인문학과 자연과학을 모두 아우르는 융합 학문분야로, 최근 들어 중등 및 고등 교육기관 교육자들의 관심을 차츰 받고 있는 분야이다. 미국에서는 현재 빌 게이츠의 지원 아래 '빅 히스토리 프로젝트'를 운영하며 중등학교 교사들이 이용할 수 있는 자료를 구축하고 제공하는 등 활발한 교육 및 연구가 이루어지고 있지만, 아직 우리나라에서는 관련 연구가 교육이 활발히 이루어지고 있지는 않다. 이번 연구에서 우리는 1) 빅 히스토리 프로젝트, 2) 새로운 모습으로 올해 소개된 다큐멘터리 '코스모스', 3) 빅 히스토리 관련 서적들의 콘텐츠를 정리하고, 이들을 시대별, 주제별, 그리고 소주제별로 분류하여 얼마나 다양한 방법으로 접근할 수 있는지 보일 것이다. 향후에는 이 콘텐츠를 대학의 교양교육과정에서 어떻게 이용할 수 있는지를 제시하는 것이 목표이다.

생태방음벽의 적합한 식물종은 최소한의 유지관리만을 통해 성장할 수 있는 식물을 선정하는 것이 매우 중요하다. 지상부의 성장이 억제되고, 지하부의 성장이 활발해야 하기 때문에 레볼센트리, 소나타, 페난트 등이 가장 적합한 식물종으로 판단된다. 코스모스의 경우는 발아율, 생명력, 번식력 등이 매우 좋으나 지하부의 성장이 다른 품종에 비해 약 35%이상 크게 성장하고 지하부의 성장이 50%미만이기 때문에 식생방음벽으로서는 적합하지 않다. 그리고 여러 조건을 충족할 수 있는 추후 실험이 이루어져야 할 것으로 사료된다.
