In order to evaluation of beneficial functions for organic farming, we have divided beneficial functions as 9 sub-functions such as flooding control, fostering water resources, purifying the air, mitigating summer climate, purifying water quality, decreasing soil erosion, accumulating soil carbon, conserving biodiversity, and preventing accidents from pesticides. And they were quantified by searching related repots and statistics, and surveying fields. Organic farming, especially organic paddy farming, showed that some functions like fostering water resources, accumulating soil carbon, conserving biodiversity, and preventing accidents from pesticides were higher than conventional paddy farming, while the others were almost similaι The foste꺼ng water resources function was evaluated as 4,297 ton ha-1 year-1 to increase about 3.6% comparing with that of conventional farming. New function for accumulating soil carbon at organic paddy fields has been assessed by 4.67 ton ha-1 in terms of long periods over 10 years. Considering area of organic paddy farming in Korea and value of carbon price， it was evaluated monetary value as 22.4 to 84.1 billion won using replaced method. It could be also evaluated that flooding control, fostering water resources, purifying the air, mitigating summer climate, purifying water quality, decreasing soil erosion, and preventing accidents from pesticides were 2,980, 123.4, 482.6, 87.5, 0.9, 55.6, and 284.1 billion won, respectively. Conserving biodiversity function would be very big at organic farming though it couldn ’l be evaluated as monetary value.

최근 기능성화장품과 피부관련 의약품 분야에서 multi-lamellar와 liquid crystal의 구조가 커다란 관심을 끌고 있다. 결합수와 고정된 유상을 함유하는 multi-lamellar 구조는 피부의 세포간지질의 lamellar 구조의 재건과 보습을 유지하는 작용으로써 보습기능이나 장벽기능의 복구에 우수하며, 이 지질들은 각질층에 침투하여 유지된다. 본 연구에서 고급 지방 알코올, 레시틴, 콜레스테롤을 사용하여 제조한 bio-mimic liquid crystal emulsion (BLCE)의 피부장벽 기능을 측정하였고 일반적인 계면활성제와 세포독성을 비교하였다.
