Post-modernism which was generally spread western civilization after World war II and used to a wide area in many fields reflects an aspect of the social and cultural as representative the spirit of the age in the late 20th century The most phenomenon that was appeared a sign of Post-modernism is the spread of popular culture. Animation which is the aim of communicating the entertainment and pleasure has a peculiar position in the result of the popular culture. Neon Genesis Evangelion can be discriminated the existing commercial animation because the process of the story, the characteristic of the work and the expression of an author are demonstrating sufficiently the Post-modernistic characteristic.

In this paper, Ive investigated algebraic concepts which are contained in Euclid's Elements. In the Books II, V, and VII∼X of Elements, there are concepts of quadratic equation, ratio, irrational numbers, and so on. We also analyzed them for mathematical meaning with modem symbols and terms. From this, we can find the essence of the genesis of algebra, and the implications for students' mathematization through the experience of the situation where mathematics was made at first.

palaeomagnetism is a major implement to define tectonic provinces and to estimate their past relative position quantitatively. In this sort of investigation it is tacitly assumed that the magnetization of the rocks under study was acquired at the time of their formation. However, because of the possibility of secondary alteration and/or replacement of magnetic minerals, this assumption is not always legitimate. To secure reliable palaeomagnetic data it is therefore fundamental to identify the carrier mineral of magnetization. This paper reviews magnetic mineralogy relevant to palaeomagnetism of terrestrial rocks. Under the heading of each mineral its genesis, crystal structure, magnetic properties, criteria for ore microscopic determination and secondary alteration are summerized. This paper should also be helpful in application of magnetic mineralogy to geothermometry and oxygen barometry in igneous petrology, diagenesis and provenance study in sedimentary petrology, metamorphic temperature determination and genesis study of ore deposits.

The goals of this papper are not only to maximize of performance but also to reduce the response time for the real-time printed alphabets recognition system using the backpropagation algorithm in the artificial neural network. The Genesis board and MIL(Matrox Image Library) package were used to real-time acquisition, processing and display of images. Through this experiment proved the possibility of real-time recognition processing by comparing response times of the system and proposing the method to reduce of order of the output vectors.

Recent studies reveal that grip forces due to repeated mechanical vasocompressions are most significant for the genesis of vibration-induced which finger syndrome (VWF). Therefore, exerted grip force was regarded as a dependent variable in 2 experiments and the effects of noise and vibrations of different weighted acceleration levels were studied. Neither grip forces nor peripheral blood flow as indicated by finger skin temperature were influenced by noise or vibrations. the cause of VWF is therefore presumed to be a concomitant variable which correlates with weighted accelerations and with grip forces as well. A possible factor is the weight of hand-held vibrating tools.

Analyzing the typhoon wind hazards is crucial to determine the extreme wind load on engineering structures in the typhoon prone region. In essence, the typhoon hazard analysis is a high-dimensional problem with randomness arising from the typhoon genesis, environmental variables and the boundary layer wind field. This study suggests a dimension reduction approach by decoupling the original typhoon hazard analysis into two stages. At the first stage, the randomness of the typhoon genesis and environmental variables are propagated through the typhoon track model and intensity model into the randomness of the key typhoon parameters. At the second stage, the probability distribution information of the key typhoon parameters, combined with the randomness of the boundary layer wind field, could be used to estimate the extreme wind hazard. The Chinese southeast coastline is taken as an example to demonstrate the adequacy and efficiency of the suggested decoupling approach.
