The purpose of this study is to investigate utilization of Akadama soil and evaluate its ion removal efficiency for seawater desalination. The chemical composition of the Akadama soil was Al_2O_3 0.334kg kg^<-1>, SiO_2 0.470kg kg^<-1>, Fe_2O_3 15.7kg kg^<-1> by weight. X-ray powder diffraction pattern, electron diffraction pattern and IR spectrum of Akadama soil showed that allophane was the main phase and low crystallinity kaolin was generated from the allophane. The column method was carried out to evaluate seawater desalination efficiency, the best mixture ratio of the Akadama soil (particle size was less than 250μm), aluminum silicate adsorbent, aluminium magnesium adsorbent, and magnesium oxide adsorbent was 3:1:1:1. Removal percentages of Na^+, Mg^<2+>, Ca^<2+>, K^+ and Cl^- from artificial seawater were 87.7, 84.4, 91.1, 97.3 and 90.7%, respectively. In the batch method, where the mixed adsorbent was used for removal of heavy metals from 20mg L^<-1> solution, the removal percentages of Cu^<2+>, Ni^<2+>, Mn^<2+>, Zn^<2+>, Cd^<2+> and Pb^<2+> were higher than 98%. The removal percentage of PO_4, from river water was 100%.

This study clarifies the relationship between sweet liking and personality, with a focus on snacking. In this study, sweet liking was defined as the degree of liking sweets, because we believe that sweets are often consumed as snacks between meals. Additionally, we investigated the times and situations in which sweet liking people want sweets, and the possibility of subjectively predicting a sweet-liking score using a visual analog scale (VAS) .We discuss the difference of the Big Five personality scores between the high and low sweet-liking groups. The results show that the high sweet-liking group demonstrates a marginally significant difference in consciousness score: it is lower than that of the low sweet-liking group. So, our data suggest that high sweeters are looser than non sweeters. Moreover, while men want sweets at various times and situations, women want sweets when they feel lonely or want to cheer themselves up. There is a significant correlation between the sweet-liking VAS and sweet-liking scores.
