To examine the inhibition effects of different industrial waste-based sorption materials on cesium transfer from contaminated forest soil to vegetation and penetrated water, pot experiment for growing Napier grass was conducted in a greenhouse by using forest soil adjusted in advance for three different cesium contamination levels with 133Cs (0, 25 mg kg−1, 50 mg kg−1) as the soil media and biochar, incinerated sewage sludge ash and carbonized sludge as the sorption materials added separately to the soil media at three different rates (0, 5%, 10%, w/w). The obtained results showed that all these three sorption materials had the capability to reduce the amount of cesium accumulated in Napier grass and that transferred to the penetrated water under the experimental conditions with cesium addition. The most obvious inhibition effect was found for the condition with the addition of 10% biochar, suggesting the possibility of using this material as an effective sorbent to inhibit the transfer and diffusion of cesium in the contaminated forest soil.
In order to realize a sustainable and subjective well-being in lifestyle, a globally optimal service, technology or social system that is entirely conceived from a subjective well-being in lifestyle is effective. Using action decomposition trees of lifestyle samples, we analyzed the relationship between various elements of human activities, social context, cultural background, environmental constraints and lifestyle, and obtained various concepts of lifestyle. These concepts in common vocabulary enables you to reuse knowledge included in lifestyle. To achieve this, we extracted the vocabulary (surface layer vocabulary) consisting of 2395 terms commonly used in 40 action decomposition trees, and examined LS standard vocabulary for each term. As a result, we finally obtained the LS standard vocabulary composed of 218 terms.
This LS standard vocabulary was evaluated in two respects. The first point is whether or not the LS vocabulary covers the terms appearing in a new action decomposition tree, and we confirmed the coverage rate was 96.9%. The second point is whether or not a new lifestyle can be designed using other action decomposition trees by replacing goal-achieving ways via the LS standard vocabulary. And we also confirmed that a few interesting lifestyles that could not be thought of by humans were created.
