Nitrogen dynamics in mineral soils of an alder (Alnus maximowiczii) stand established on volcano Mt. Showa-Shinzan were measured by laboratory incubation method in order to clarify characteristics of $NH_{4}^{+}$ mineralization and nitrification rate, from August 1994 to July 196. Contents of total N and organic matter were relatively low, but increased in May-July. Extractable $NH_{4}^{+}$ concentrations and $NH_{4}^{+}$ mineralization were high in June and July, and decreased in midsummer and fall. Extractable $NO_{3}^{-}$ concentrations did not vary seasonally. Negative values at $NH_{4}^{+}$ mineralization and nitrification rate were observed in August and September. $NH_{4}^{+}$ mineralization was positively correlated with soil organic matter, and nitrification rates were influenced by extractable $NH_{4}^{+}$ concentration and $NH_{4}^{+}$ mineralization.

To clarify the soil N dynamics, the relationship between soil N and vegetation recovery after volcanic eruptions was investigated in two stands dominated by black locust(Robinia pseudo-acacia L.) on volcano Mt. Showa-Shinzan, northern Japan, from August 1999 to July 1996. No significant differences were observed between the two stands with respect to soil chemical properties and soil extractable N. At both stands, total N concentration were high in spring and declined through the summer and fall. The peaks in concentrations of extractable $NH_4{^+}$ and $NO_3{^-}$ occurred in July at both stands. $NH_4{^+}$ mineralization showed a conspicuous peak in June and July throughout the study period. Extractable $NO_3{^-}$ concentration and nitrification rates at the two stands during the study period were relatively high. Negative values for $NH_4{^+}$ mineralization at both stands were found in August. Extractable $NH_4{^+}$ and $NO_3{^-}$ concentrations were correlated positively with soil organic matter, and nitrification rates were controlled by $NH_4{^+}$ mineralization and extractable $NH_4{^+}$ concentration at both stands.

The paper holds its purpose to analyze the descriptive function and meaning of first person animation which the focalizer, character, and all narrators are indicated as 'I', For the purpose, the following was reviewed; the relation between 'I' as child memorizing the days of childhood as adult and the current 'I' as adult, and the aesthetic effect of experience and sense of the child on the audience reading the narration. The retrospective narrating situation of the adult narrator brings descriptive effect which comes from 'the tension between the experiencing self (self as child) and the narrative self (self as adult). The works focus on the content of child experience through the confession of the adult narrator, but the view of the adult always heading towards 'the present'. That is, the aesthetics contained by the first person narrator is related to endless arousal of the values of hidden and forgotten things. In addition, the descriptive method of child focalizer as 'the subject of experience' brings qualitative change which enables reasoning of the subject as itself, which is free from the view tamed by rational system. Becoming an adult, the lost ability of mimesis brings qualitative change by meeting with the generality of childhood sense. Therefore, it can be known that the meaning the narrator contains in the first person narrator condition of animation links with the degree of aesthetic completion of the work, but also, it is a highly strategic descriptive device which determinately affects even the acceptance of audiences regarding the work.
