Since 1997, Korean Ministry of Knowledge Economy and Ministry of Environment have established data on some 400 basic raw and subsidiary materials and process like energy, petro-chemical, steel, cement, glass, paper, construction materials, transportation, recycling and disposal etc by initiating establishment of LCI database. Regarding agriculture, Rural Development Administration has conducted establishment of LCI database for major farm products like rice, barley, beans, cabbage and radish etc from 2009, and released that they would establish LCI database for 50 items until 2020 later on. The domestic LCI database for seeds, seedling, agrochemical, inorganic, fertilizer and organic fertilizer etc is only at initial stage of establishment, so overseas LCI databases are brought and being used. However, since the domestic and overseas natural environments differ, they fall behind in reliability. Therefore, this study has the purpose to select organic farming materials, survey the production process for various types of organic farming materials and establish LCI database for the effects of greenhouse gas emitted by each crop during the process. As for selecting methods, in this study organic farming materials were selected in the method of direct observation of material and bottom-up method a survey method with focus on the organic farming materials admitted into rice production. For the basic unit of carbon emission amount by the production of 1kg of organic farming material, the software PASS 4.1.1 developed by Korea Accreditation Board under Ministry of Knowledge Economy was used. The study had the goal to ultimately provide basic unit to calculate carbon emission amount in executing many institutions like goal management system and carbon performance display system etc in agricultural sector to be conducted later on. As a result, emission basic units per 1kg of production were calculated to be 0.04968kg-$CO_2$ for oystershells, 0.004692kg-$CO_2$ for expanded rice hull, and 1.029kg-$CO_2$ for bordeaux mixture liquid.

우리나라의 미기록 병인 Rhizoctonia solani Kuhn에 의한 배추 밑동썩음병(Bottom rot)에 대한 남부지방파로재배 시의 발병소장과 방제방법을 검토하였다. 본 병의 발병은 정식 20여일 경과후, 배추의 생육중기부터 발병되기 시작하여 결구기에 증가하는 경향이고, 수확기의 발병주율은 평균 $52\%$ 정도였다. 그 피해는 추파로지재배보다 비닐하우스를 이용한 반촉성재배에서 심하였고, 초기에 심엽까지 감염된 이병주는 위축되어 생육이 극히 불량하여 결구가 되지 않았다. 병주에서 분리한 R. solani의 PDA배지상에서 균사 생육적온은 $20\~25^{\circ}C$였고, 균사융합군은 제II군 제1형으로 분류되었다. 배추, 무, 참깨 및 유채의 유묘에 접종했을 때 입고율이 매우 높았고 상치, 토마토, 오이에서는 입고율은 낮았으나 발아가 $2\~3$일 지연되었다. 방제약제는 발병초기부터 pencycron Wp.를 10일간 3회 처리한 것이 방제가가 $80\%$로 우수하였다.

Therefore, this study has the purpose to select organic farming materials, survey the production process for various types of organic farming materials and establish LCI database for the effects of greenhouse gas emitted during the process in order to select carbon basic units for agricultural production system compliant in domestic situation instead of relying on overseas data and apply life cycle assessment of greenhouse gas emitted by each crop during the process. As for selecting methods, in this study organic farming materials were selected in the method of direct observation of material and bottom-up method a survey method with focus on the organic farming materials admitted into rice production.

As a result, emission basic units per 1kg of production were calculated to be 0.0088kg-$CO_2$ for charcoal, 0.1319kg-$CO_2$ for grass liquid, and 0.2804kg-$CO_2$ for microbial agent.

본 연구는 기능성을 가진 무말랭이 김치를 개발하기 위하여 당귀잎을 물과 70% 에탄올로 추출하여 추출물의 전자공여능, 아질산염 소거능 및 항암활성을 검토하고 당귀잎을 0-3% 첨가한 무말랭이 김치의 품질특성을 조사하였다. 당귀잎 추출물의 전자공여능은 물 및 에탄올 추출물 모두 추출물의 농도가 증가함에 따라 전자공여능도 증가하였으며 100${\sim}$1,000 ppm에서 물 추출물은 40-80%, 에탄올 추출물은 37-81%로 우수한 항산화능을 나타내었다. 추출물의 아질산염 소거능은 pH가 낮아짐에 따라 증가하여 pH 1.2에서 가장 높았고 동일 pH에서는 농도의존적으로 증가하였다. 당귀잎 추출물의 아질산염 소거능은 pH 1.2, 1,000 ppm 농도에서 물 및 에탄올 추출물은 각각 29%, 35%였다. 당귀잎의 물과 에탄올 추출물 1,000 ppm의 유방암세포(MDA cell)에 대한 증식 억제율은 각각 35%, 32%, 폐암세포(A549 cell)에 대한 증식 억제율은 각각 27%, 23%였다. 무말랭이 제조를 위하여 무를 햇볕에서 15시간 동안 자연건조 시켰을때 수분함량은 여름무(39.5 %)가 가을무(32.6%)에 비하여 높고, 여름무는 건조과정에서 갈변현상을 나타내었다. 당귀잎을 1-3% 첨가한 무말랭이 김치를 20$^{\circ}C$에서 4주간 저장하였을 때 당귀잎 첨가량이 많을수록 효모수가 낮았으며 당귀잎 첨가에 의하여 무말랭이 김치의 저장성이 향상되었다. 무말랭이 김치의 관능검사 결과, 맛, 색상, 물성, 향, 뒷맛, 종합적인 기호도에서 당귀잎 2% 첨가한 김치가 가장 높은 점수를 얻었다. 특히 맛과 종합적인 기호도는 당귀잎 2% 첨가구에서 유의적으로 높은 기호도를 나타었다(p<0.05).
