In this paper, we developed to artificial neural network for load characteristic identification of power system. We can acquire active power and reactive power of individual load depending on the variation of voltage and frequency from the experimentation of a dynamic characteristic of load. The data of the experimental results were be used in learning of ANN. A proposed ANN model is applied to analyze the transient stability. To demonstrate the propriety of the power system transient stability with load model using ANN, the simulation of the two-machine five-bus system is carried out.

This study was carried out to investigate the ecological characteristic of native Lithospermum erythrorhizon population in Korea. The survey quadrates were located in the middle of native L. erythrorhizon habitats. As the result of the research, the ecological patterns of native habitats were found to be divided into inclined plane type, ridge type, mountain-roadside type, and rock bed type. The research revealed 90 taxa in total, in which 37 families, 63 genera, 23 varieties, 6 forma, 1 sub-species and 60 species were checked in the flora of native L. erythrorhizon habitats.

Statistical interpretations in a bioequivalence trial are considered and studied when the missing observations occurred in $2\;{\times}\;2$ crossover experiment. Patel (1985) suggested the approximate test procedures for carryover effect and drug effect in $2\;{\times}\;2$ crossover design when some of data are missing in the second period. A modified Patel method is newly proposed to the bioequivalence trial and it is compared with the current method through the simulation study.
