패시브하우스는 주거공간에 필요한 공기량을 단지 신선한 외부의 공기만을 데우거나 식힘으로 실내 열적 쾌감을 만족 시킬 수가 있는 건물을 말한다. 이 정의는 단지 기능적인 표현이며 어떠한 절대적 수치를 포함하지 않으며 어떤 기후에도 적용된다. 패시브하우스 용어의 선택은 임의적으로 지어진 것이 아니라 건물의 계획과 사용에 있어서 최대한 간접적인 수단으로 열적 쾌적함이 이뤄 질수 있도록 노력하는 것이며, 직접적인 수단은 최소화 시키는데서 이루어진 것이다. 직접적인 수단은 단지 꼭 필요한 것과 필요한 곳에 한정해 최소화 시키는 것이 궁극적인 목적이다. 이러한 패시브하우스 도입은 온실가스 감축, 고유가 등 환경변화에 대응하기 위한 것으로 디자인에서부터 자재사용까지 전 과정에 걸쳐 이뤄지고 있다. 본지는 국내에 적용 중이거나 적용할 예정인 패시브하우스에 대해 알아본다.

앞으로 환경문제에 대한 대책은 더욱 급속한 스피드로 진행되어 갈 것이다. 그 가운데 품질과의 양립이 중요해지지만, 사용하는 인쇄기의 성능을 최대한 끌어올려 높은 인쇄품질을 실현하려면 사용하고 있는 자재의 밸런스가 좋은 상태를 유지해야 한다. 오존층의 파괴 등 지구 온난화를 비롯한 지구 규모에서의 환경보호에의 대책은 기업이 솔선수범하여 도전할 테마다. 동시에 인체에도 영향이 적은 제품개발이 무엇보다 중요하다. 일반적으로 인쇄는 잉크 또는 롤러와 밀접한 관계를 가지고 있다. 잉크의 특성으로 인해 인쇄물의 건조가 되지 않거나 잉크의 지지도가 나쁘게 되며 세척에 많은 시간을 요구하게 된다면 인쇄 품질을 기대하기는 어려울 것이다. 또한 롤러를 반복적으로 세척하고 새로운 것으로 교체하는 경우에도 작업 능률의 저하를 가져 올뿐만 아니라 작업자의 피로를 유발하여 안전사고 위험에도 쉽게 노출될 수 있다. 이에 이러한 문제점들에 대해 알아보았다.

This study was conducted to investigate foliar treatment effects of organic agricultural materials for the environmentally-friendly cultivation of grape. The organic materials applied were chitosan, wood vinegar (pyroligneous acid), amino acid solution, and ginkgo leaf extract. All the organic materials were relatively strong acidic ranging lower than pH 4.6. when comparing with other organic materials, amino acid solution contained relatively high contents of selected plant nutrients, such as N, P, K, Ca, Mg, Cu, Fe, Mn, and Zn. As comparison of selected soil properties in the grape cultivating field, soil pH values were lower at the harvest stage than at the first stage of grape growing (before treating the organic materials), and electrical conductivity (EC) and soil organic matter content were higher at the harvest stage in the all plots. The concentrations of available phosphorus increased in most of the plot soils except in control plot (conventional treatment). The concentrations of exchangeable K decreased in the plot treated with ginkgo leaf extract and the control plot. The exchangeable Mg concentrations decreased in soils of all the plots. On the other hand, the concentrations of N and K in the grape leaves were higher with the treatments of chitosan and amino acid solution, P concentrations were higher with the applications of chitosan, wood vinegar and amino acid solution, and Ca and Mg concentrations were higher with chitosan and amino acid solution treatments, respectively, than with others. The yields of grape were higher, $1,581{\sim}1,583kg\;10a^{-1}$, in the control and wood vinegar treatment plots than others. Sugar contents of grape were not different among all the plots.

Coming with the well-being era, consumer's demand for safe agricultural products is increasing. So, it is urgent to develop an environment-friendly rice production system. Accordingly, this study was conducted to develop an environment-friendly rice production system by using Amo known as EM(effective microorganisms) and also known as being effective in environment-friendly rice production with several other environment-friendly agricultural materials. The highest number of tillers per hill was obtained from level 2 of EM treatment (48.8 tillers per hill), while the lowest was obtained from the control plot (41.0 tillers per hill). Leaf area per hill at heading stage was the highest in level 3 of EM treatment $(3228.5cm^2)$, while control was the lowest leaf area $(2264.7cm^2)$, which is 70.2% compared to the level 3 of EM treatment. The highest effective tillers was obtained from the control (63.7%), while the lowest effective tillers was obtained from the level 3 of EM treatment (55.4%), which were treated with higher amounts of environment-friendly agricultural materials. Level 3 of EM treatment showed the highest number of panicles per hill (20.9), while the control showed the lowest number of panicles per hill (19.3). In the spikelets per panicle, level 2 of EM treatment showed the highest number of spikelets (85.2), while the control showed the lowest number of spikelets (81.9) and there was a statistically significant difference among the three levels and control. The highest grain filling ratio was obtained from the control (85.0%), while level 3 of EM treatment was the lowest grain filling ratio and there were no great difference between treatment levels. Regarding the 1000 grain weight, the control showed the highest 1000 grain weight (21.7g), which is heavier by about 1g compared to treatment levels. Level 2 of EM treatment showed the highest rough rice yield per 10a, while level 3 of EM treatment was the lowest and they also showed a statistically significant difference among treatment levels.

This study was performed to test the insecticidal and antimicrobial activity of plant extracts from clove, Sophora flavescens Aiton and neem. As the result of antimicrobial activity test, clove extract showed the strongest activity against Botrytis cinerea. In insecticidal activity test, the extract of Sophora flavescens Aiton was the highest against Nilaparvata lugens. The pyroligneous liquor (10%) and emulsified spreader (10%) were added to the extracts of clove and Sophora, respectively, to apply the environment-friendly rice field. In the field treated clove extract, disease damage occurred 49.1% and insect damage occurred 29.5% compared to control plot (100%). In the field treated Sophora extract, disease damage was 56.7% and insect damage was 21.0% compared to control plot (100%). In conclusion, plant extracts from Sophora and clove could control about 50% of disease and about 70% of insect damage that they could be used as environment-friendly resources to control disease and insect in rice farming.
