In this paper, considering the limits of existing smart pots, we introduce the research result of the new smart pot that can easily grow various pet plants. Through Arduino control kit which is the one of the open source computing platform, electric circuit and equipment to fulfil the functions of the smart pot is newly designed and made. Especially the head of pump which is main function in smart pot and the structure of electric equipment is theoretically calculated and Finite Element Analysis (FEA) tool is used for static analysis to prevent damage to the pots. After that, new smart pot is made with the researched design materials and perform the various functional investigations to grow the indoor plants.

투수성이 높은 토양에 대한 동전기세정 제염의 영향을 평가했다. 실험토양은 많은 모래를 함유하여 수리전도도가 높은 연구 원자로 주변부지로부터 채취했다. 세정용액의 방출속도는 제염시간 경과와 함께 감소했다. 시트릭산을 사용했을 때, 세정용액의 방출속도는 78.7 ml/day로 가장 빨랐다. 세정용액으로 초산을 사용하였을 때, 토양으로부터 코발트와 세슘의 제거효율은 가장 높은 값인 95.2%와 84.2%를 나타냈다. 동전기제염 시 발생된 토양 폐액부피는 토양세척제염시보다 1/20으로 감소했다. 반면에 동전기세정방법은 토양으로부터 코발트와 세슘 제거효율을 동전기방법 보다 각각 6%와 2%로 향상시켰다. 그러므로 동전기세정방법은 투수성이 높은 토양제염 시 좀 더 효과적이다.

In order to analyze the horticultural elements expressed in fairy tale books for preschoolers, a total of 318 books were analyzed from the top 150 books borrowed at the Seoul City Children’s Public Library and the books classified at the three major online bookstores in Korea. Horticultural elements were largely classified into horticultural plants, horticultural activities, and information of authors. The result pursuant to the classification based on horticulture appeared to be highest for flowering trees 77%, and the instances in which the name of the plants appeared in writing in the stories appeared to be 36% and regarding the diversity of plants, appearance of six species or more occupied the highest ratio. As a result of analyzing the weight of horticultural elements expressed in fairy tale books, there appeared to be a total of 56 books in which the horticultural elements were expressed 100%. The horticultural elements expressed in fairy tale books mostly appeared to be highly expressed when the author had horticultural experience. According to the result of this research, the expression frequency of horticultural elements appeared to be high overall, but it has been appeared passive expressions.
