Currently, methods for controlling weeds in organically produced crops have not been as effective as conventional methods. This research was carried out to determine the herbicidal effects of leaf, stem, fruit, root extracts of Trichosanthes kirilowii. The extraction methods used were water, boiling water and ethanol. The characteristics of potential herbicidal components among extraction methods were investigated by using the following solvent fractions: hexane, chloroform, ethyl acetate, butanol, and water. Generally, water extracts provided the best on inhibition of germination rate, plant height, and root length in cucumber and barley. Specifically,extractions made from fruit parts of T.kirilowii provided the greatest inhibition effect on plant growth in cucumberand barely. Inhibition of germination rate, plant height, and root length in cucumber and barley in solvent fractions was the best in water fractions, but there were no significant differences among the other fractions. Digiraria siliaris and Solanum nigrum were controlled 80-100% by 5% extractions of water fraction. However, there were no herbicidal effects from foliar treatment in cucumber, barley, black nightshade, and henry crabgrass by 5% extractions of the water fraction. These results show that extractions of T. kirilowii can be used for conrtolling some weeds in organically produced crops. 현재 유기재배에서 잡초 방제를 위한 방법은 관행방법에 비해 효과적이지 못하다. 본 연구는 하늘타리의 잎, 줄기, 열매, 뿌리 추출물 중 어느 부위에서 제초 효과가 가장 높은지를 알아보기 위해서 각 부위별로 물, 열수 그리고 에탄올로 추출하였다. 또한 위의 추출방법 중 제초활성능력이 뛰어난 것을 hexane, chloroform, ethyl acetate,BuOH, H2O로 용매분획하여 잠재적 제초 성분에 대한 특성을 조사하였다. 전반적으로 오이와 보리의 발아율, 초장 및 근장 억제는 추출방법 중 물 추출법이 가장 효과적이었고, 식물체 부위별로는 열매에서 가장 효과적이었다. Ethyl acetate, butanol, chloroform, hexane, water의 용매분획에서 오이와 보리의 발아율, 초장 및 근장 저해는 물 층에서 가장 좋았고 그 밖의 분획에서는 차이가 없었다. 5%물 층 추출물 발아전 처리에 의해 바랭이와 까마중의 생장량은 80~100% 억제되었으나, 이 추출물에 의한 오이와보리뿐만 아니라 잡초종(바랭이, 까마중 등) 경엽처리에의한 생육저해 효과는 없었다. 본 연구결과로 볼 때 하늘타리 추출물을 친환경 또는 유기농 재배에 잡초방제를 위해 사용할 수 있을 것으로 본다.

This study was carried out in order to evaluate the growth promotion effects on tomato crops and to assess the mineral nutrient concentrations of farm-made liquid fertilizers used in organic cultivation in South Korea. We hope that this study will help to develop of a standardized manufacturing technique for these organic liquid fertilizers. We collected 62 farm-made liquid fertilizers made from various raw materials including fish, seaweed, food scraps, plant and crop by-products, and other materials. Two groups of tomato seedlings were treated at different times, one at 20 days and the other at 40 days after sowing. We used both foliar and soil applications. These seedlings were treated using liquid fertilizers at various dilution rates (x1000, x500 and x100). When foliar application was used, seedlings after 20 days had a 20-30% increase in shoot fresh weight with 47-48 fertilizers and seedlings after 40 days had a 20-30% increase in shoot fresh weight with 17-32 fertilizers. When soil application was used, seedlings after 20 days had the same increase in shoot fresh weight with 30-31 fertilizers and seedlings after 40 days also saw the same increase with 6-7 fertilizers. Therefore, our studies showed that application of liquid fertilizers to seedlings 20 days after sowing was most effective and that foliar treatment was more effective than soil treatments. We also observed that the higher the concentrations of fertilizer, particularly when applied twice rather than just once, the higher the rates of growth, which promoted shoot fresh weight more than plant height. Our results imply that mineral nutrients in liquid fertilizers seem to be the probable cause for the growth promotion observed in this study. However, more study is required to determine exactly which mineral nutrients are most effective.

멀티미디어 콘텐츠에 대한 고찰 - 디지털 네트워크 중심으로
윤영범 한국공학안전보건예술학회 2010 한국공학예술학회 논문지 Vol.2 No.-
디지털 네트워크상의 멀티미디어 콘텐츠 활용은 급속히 확대되고 있으나 그 특성에 대한 연구는 부족한 실정이다. 본 연구에서는 커뮤니케이션의 측면에서 자연발생적이고 생물학적인 세대적 진화과정을 거쳐 모종의‘디자인표준’을 형성한 멀티미디어 디자인의 특징을 분석하여 콘텐츠 플래닝의 전망을 제시한다. Despite multi-media contents over the digital network has been put to practical use in many ways, The study of its attribute has been insufficient. This paper brings forward an alternative vision in terms of multi media contents planning with design standard.

본 연구의 목적은 중세시대 시각예술의 특징이었던 성상숭배와 이콘의 언어적 요소를 분석하여 시각적 표현을 위한 스 토리텔링의 본질을 탐구하는 것이다. 기독교 교리의 메시지를 보여주는 묘사와 질서의 종교적 교의(敎義)와 미술양식은 서 구예술에 많은 영향을 미치며 전승되었다. 중세시대의 서구예술에 나타나는 시각적 특성을 분석한 결과 예술작품은 언어 적 요소의 시각화를 통해 세계를 재현하고 있으며 이러한 의미는 사회학적 접근을 통해 이해될 수 있다. 예술작품은 언어 적 해석의 대상으로서 재현의 대상인 실제하는 사물과 철학적이고 존재론적인 관계를 형성하고 있다. 결론적으로 모든 시 대와 문화를 초월하여 예술의 본질은 스토리텔링이며 예술 행위는 표상을 보여주려는 상징적인 사고를 통해 이루어진다. 예술적 창작의 본질은 스토리텔링이며 스토리텔링의 목적은 설득과 소통이다. The objective of this study is for analyzing Implications of Iconophily and Icon in the Middle Ages to explore the elements of visual storytelling. In terms of figurative feature with Christian Doctrine, Iconophily and Icon are having common denominator. In particular, Style of religious messages and art forms had been effect European Art for long times since paleolithic era. According to result that analyze of visual special quality that appear in the Middle Ages. As a result of analyzing the visual characteristics, Iconophily and Icon represent the Christian Doctrine via the visualization of linguistic elements that can be understood through a sociological approach. Works of art are the subject of linguistic analysis and has formed the philosophical and ontological relationships with reality. In conclusion, transcending all ages and cultures to the nature of the art is storytelling and acts of art is to show the representations of symbolic thinking. The nature of artistic creation is storytelling for the purpose of communication and persuasion.
