Objectives: The main objective of this study is to investigate domestic usage amount of insecticide for vegetable cultivation to provide fundamental data for establishing job-exposure matrix(JEM) related to farmers treating agricultural insecticide. Materials and Methods: The survey on domestic usage amount of insecticide for vegetable cultivation was conducted by two research methods. The first method is to utilize agricultural pesticides published annually from Korea Crop Protection Association(KCPA). The second method is to apply cultivation area of vegetable announced officially from Statistics Korea(SK). An estimation of domestic usage amount of insecticide for vegetable cultivation through the second method was done by multiplying total cultivation area of vegetable($m^2$) with optimal spray amount of insecticide for vegetable cultivation per unit cultivation area of vegetable ($kg/m^2$). Results: As a result of analysis of public data related to insecticide for vegetable cultivation, it was found that its domestic usage amount has decreased gradually from the first sale year(1969) to current year(2012). There is, however, a considerable difference of annual usage trend of insecticide for vegetable cultivation between shipments and estimation. The annual usage trends of insecticide for vegetable cultivation based on regional classification were different from those based on total aspect. Conclusions: The region which used insecticide for vegetable cultivation the most in Korea was Jeolla-do, followed by Gyeonsang-do, Chungcheong-do, Seoul/Gyeonggi-do, Gangwon-do and Jeju-do. Substantially, mean ratio of usage amounts of insecticide based on shipments and those based on estimation by cultivation area was $281{\pm}115%$, which indicates that usage amounts of insecticide estimated by cultivation area are three times lower than those based on shipments.

인삼은 우리나라를 대표하는 약용작물로 남한뿐만 아니라 북한에서도 매우 중요하게 취급되고 있다. 그러나 북한에 대한 정보 접근이 어렵기 때문에 실제 북한에서 인삼의 재배, 연구와 개발 동향, 관련 산업 현황에 대해서는 잘 알려지지 않고 있다. 본 논문에서는 비록 제한적이긴 하나 구할 수 있는 서지 자료를 통해 북한에서의 인삼 산업 현황과 연구 동향을 파악하고자 하였다. 북한약전에는 인삼이 "고려인삼"으로 수재되어 있으며 '개성지방에서 재배한 6년생 인삼의 뿌리'로 정의하고 있다. 또한 북한약전에는 22종의 인삼제제가 수재되어 있다. 북한에서는 필수약품(2002) 중 건위소화약, 지사약, 보약 등 10개 약품에 인삼이 들어가고, 그 외에도 다양한 건강보조식품과 화장품, 치약 등이 개발되어 유통·판매되고 있다. 2014년 이후 북한에서 인삼 산업과 연구가 전반적으로 활발해지고 있다. 이때 개성의 인삼재배지역을 대폭 확장하고 설비를 보수하였다. 2016년, 개성고려인삼가공공장을 무균화, 현대화, 무진화된 설비로 정비하여 가동 중이라고 한다. 2017년 이후 품질관리 연구에 관심을 돌려 2019년 품질관리규정과 인증제를 도입하기에 이르렀다. 1990년대에 인삼 제품개발 연구가 많았고 2000년부터 인삼의 약리작용 및 치료·임상연구에 대한 연구가 보고되었다. 또한, 수확량을 높이기 위한 인삼재배와 인삼가공업 관련 연구가 중시되고 있다. 인삼은 우리나라를 대표하는 약용작물이라는 점, 남과 북이 모두 중요시하고 있다는 점, 남과 북이 상호 협력하면 큰 시너지 효과를 얻을 수 있다는 점에서 남북 교류협력에 있어서 매우 적합한 소재이다.

Microalgae are aquatic microorganisms capable of photosynthetic growth using water, carbon dioxide and sunlight, and can replace petroleum for transportation. It is receiving great attention as a potential next-generation biological resource. The microalgae biodiesel production process is largely based on the development of highly efficient strains and mass production. It consists of cultivation, harvesting, oil extraction, fuel conversion and by-product utilization. Currently, microalgae diesel is 3-5 times more expensive than petroleum diesel. However, with the optimization of each element technology and the development of integrated systems, not only biofuels, but also industrial materials, wastewater treatment, and greenhouse gases As application expands to various fields such as abatement, the timing of commercialization may be brought forward. Oil prices have recently fallen due to the influence of sail gas. Although there has been a significant drop, global warming is an urgent challenge for current and future generations. In particular, Korea, which does not have oil resources, We must always prepare for political environmental changes, high oil prices, and energy crises. In this paper, the need for eco-friendly biofuel for carbon dioxide conversion. In addition to research trends, domestic and international research trends, and economic prospects, the concept of microalgae and the element technologies of the biodiesel production process are briefly discussed introduced.
