1) In southern part of Japan, the time of flowering of Artemisia princeps Pamp. is late september to early october. As the results of experiments the flowering was observed under short day (8 hours light), and did not under long day condition (continuous light). 2) Number of head per plant was 2,000〜14,000, and a head consisted of about 15〜17 florets. On the other hand, the rate of fructification of the florets was about 2〜40 per cent, averaged about 20 per cent. From the results, number of seeds per plant was about 5,000〜40,000. 3) About 20 days after flowering, the seeds had an ability of germination, and it reached maximum after about 50 days. This result showed that the seeds had no dormancy. From our observations, it seemed that the seeds germinate from late autumn to early winter and pass through winter season with cotyledonary plants. 4) Effect of temperature on germination of the seeds was as follows: minimum temperature O〜5℃, optimum temperature ; 20〜30℃, maximum temperature ; 35〜40℃. 5) The rate of emergence of cotyledonary plants war good under the soil of 10〜20 per cent soil moisture content, and it decreased with the increase of soil moisture content. However, the seeds were able to germinate in boiled water, and it grown up to 6 leaf stage under the water. 6) The rate of emergence was also affected by the depth of seeding, and it decreased with the increase of the depth of seeding. As the effect of soil compaction of cover soil after seeding, in the plot of 0.1kg/cm^3-compaction 30 per cent of seeds emerged at O. 5 cm-seeding depth and did not emerge at 1.0cm-seeding depth. In the plot of 0.2kg/cm^3-compaction no emergence occured even at the plot of 0.5cm-seeding depth.

A mixed solution of 28% of ammonia and pyridine (9 : 1 (v/v)) was used to extract dye ink from counterfeit paper money printed by an ink-jet printer. The counterfeit paper money was fixed on a vacuum filtration device instead of a membrane filter. The extracted solution was collected in a test tube and was evaporated to dryness under reduced pressure in a 40°C water bath. The extract was dissolved by 10 μl of the extraction solution and spotted on a silica gel plate. The silica gel plate was developed by iso-propanol : 28% ammonia : pyridine (2 : 9 : 1 v/v/v). By comparison with TLC patterns, we could clearly distinguish among the various printer companies. Furthermore the TLC pattern was discriminated between the machine types to some extent.

過疎農山村地域の独居後期高齢者の現在・今後の生活への思いを明らかにすることを目的にA町の6名に半構成的面接を行った。【猿や猪が農作物を喰い荒らして困る】【欲を言えばもう少し交通の便を良くして欲しい】と山間部特有の問題【年々歳をとってこのまま元気でいられるかどうか先のことはわからず不安だ】【みんな歳をとり昔のようにいかなくなり悔しい】【災害や跡継ぎがないことが心配だ】等の加齢変化の実感と不安を抱えていた。これらに【みんなとの交流は楽しみだ】【みんなが支えてくれてるので安心して生活できる】と田舎ならではの良さが勝り【ここでの今の生活は幸せだ】【子供の所へ行くより住み慣れたここに最期までいたい】と自ら今の生活を選択し【今の生活を維持する為にいろんなことを心掛けている】と日々努力をしていた。鳥獣被害対策、交通サービスの充実、現存の住民支援ネットワークの活用、役割保持の支援の必要性が示唆された。
