현재 대다수의 국내 온실농장관리자는 온실내 작업자들의 농작업을 농가경영기록장(농장일지)을 이용하여 수기로 기록하고 있다. 이런 방법은 농작업 기록의 실수, 기록 후 분석을 위한 컴퓨터입력에 어려움, 작기별 비교분석의 어려움 등으로 농가경영기록장의 활용성이 매우 떨어지고 있다. 이에 본 연구에서는 NFC 기능을 이용하여 작업자들의 작업위치, 작업시간, 작업내용 등을 자동으로 기록하고 분석할 수 있는 스마트농작업관리시스템을 제안한다.

Liriope platyphylla has been though as an useful medical plant to improve the cough, sputum, neurodegenerative disorders, obesity, and diabetes in Korea and China from old times. In order to investigate the effects of Liriope platyphylla on expression and secretion of nerve growth factor (NGF), the mRNA expression and protein secretion were detected in the neuronal cell (B35) and neuroglial cell (C6) cultured with three differences concentration (5%, 10%, 15%) of Liriope platyphylla. In MTT assay and FACS anslysis, the some death of some B35 and C6 cells were observed in 15% extract-treated group, while other groups did not induce the death. Also, the mRNA expression of NGF were significantly increased in 5% and 10% extracts treated-group. Furthermore, the NGF protein concentration in supernatant collected from cultured cells showed the very similar pattern with mRNA expression. In order to verify the activity of secreted NGF, the culture supernatant collected from B35 and C6 cells cultured with Liriope platyphylla extracts for 24 hrs were treated into undifferentiated PC12 cells, and the differentiation level of PC12 cell were also observed with microscopes. The differentiation level of PC12 cell were significantly increased depend on the dose of extract. Therefore, these results suggested that the water extracts of Liriope platyphylla may contribute the regulation of NGF expression and secretion in the neuronal cell and be considered as an excellent candidate for a neurodegenerative disease-therapeutic drug.
