        2년마다 실시되는 UN의 전자정부시스템 평가에서 한국의 전자정부 시스템은 2010, 2012, 2014년 3차례 걸쳐 1위로 평가되었다. 1978년 시작되어 이제는 해외로 수출까지 되는 한국 전자정부 시스템의 진화에 있어서 표준의 역할에 대해서는 그다지 알려진 바가 없 다. 한국의 전자정부 시스템 발전에 어떠한 표준들이 어떠한 역할을 수행했으며, 이러한 표 준이 제대로 기능하기 위하여 어떠한 제반 환경이 필요하고, 어떠한 노력이 경주되었는지 사 례 연구를 수행하여 밝히고자 한다. 행위자 연결망 이론(Actor Network Theory)과 구조화 이론(Structuration theory)을 이론적 기반으로 하여, 표준이 행위자 연결망 이론 관점에서 어떠한 역할을 수행해 왔는지를 전자정부 시스템 발전에 직접 관여되었던 행정자치부 전자 정부담당 현/전직 관리자급 공무원, 표준담당관, NIA 표준 담당관, 민간 SI 업체 등 관련 전 문가(관리자급)분들과의 인터뷰와 문헌 연구를 바탕으로 사례 분석을 실시하고자 한다.

        Background : This study was conducted to serve as a basis for the production of high quality organic cultivation Platycodin grandiflorum Ridix roots by analyzing the content of saponins according to organic fertilizer for organic farming. Methods and Results : Platycodin grandiflorum Ridix was treated by with biodegradable film, rice husks, and sawdust, non-mulching (hand weeding). A root of Platycodon grandiflorum were analyzed saponins using HPLC harvested on October. Content of Plantycodin D3 was an average of 68.5 ㎎/100g, which appeared as 111.2 ㎎/100g highest content in the sawdust treated. Deapioplatycodin D showed the highest 48.1 ㎎/100g in the sawdust treated. The content of Platycodin D was shown to 246.2∼373.8 ㎎/100g, the highest values were observed in non-mulching, it showed the lowest value in the rice husks treated. The content of Polygalacin D showed up to 156.0 ㎎/100g in the non-mulching as the biggest difference, the lowest value were 30.1 and 32.2 ㎎/100g in sawdust and rice husks treated. Large differences between fertilizers was not showed, but the overall saponin content of Platycodin grandiflorum Ridix were low in value compared to the control than organic fertilizers. Conclusion : Large differences between mulching materials was showed, thus the overall saponin content of Platycodin grandiflorum Ridix was highest in value compared to non-mulching than sawdust treatment. Mulching Platycodin grandiflorum Ridix with sawdust was an effective method for improving saponin contents.

        Background : The root of Platycodin grandiflorum has been widely used as a crude drug or a dependent on the cultivation area and cultivation method. Therefore, this study was conducted to know the effect of organic fertilizer on the changes of antioxidents and antioxidant activity of Platycodin grandiflorum Ridix. Methods and Results : As basal fertilizer were treated before transplanting Platycodin grandiflorum Ridix with chemical fertilizer(Super21, 21-17-17, Namhae Chemical), mixed organic fertilizer, bacterial culture, fermented oil cake and manure in each trial of nitrogen based on 3㎏/10a criteria. The total polyphenol content was highest values were 15.5mg/g appear in the mixed organic fertilizers, the lowest were 9.1mg/g appeared in the manure and control. Flavonoid content showed the highest 15.3 mg/g in the mixed organic fertilizer, and investigated at the lowest 5.0 mg/g in the fermented oil cake. ABTS radical scavenging activity was the highest in was 65.7 mgTE/g in the chemical fertilizer, showed the lowest value in the control to 13.0 mgTE/g. Therefore, both flavonoid and polyphenol content showed a high value on organic fertilizers. Conclusion : Therefore, both flavonoid and polyphenol content showed a high value on organic fertilizers. It is determined that to have researches for a variety of antioxidants by the organic fertilizers made in the future.
