In the history of cinema, Sergei Eisenstein is always considered as a pioneer to conceive of cinema primarily as a form of expressing thought rather than as a representation of reality. For him, montage is the indispensable method to construct an open totality of thought and image in movement. It functions as a basic thread running through two poles of filmic composition, that is, the organic and the pathetic. The organic is concerned with the composition of the film structure as a whole, while the pathetic is involved in an ongoing process of registering a leaping point in various filmic sequences. The ultimate goal of montage for Eisenstein is to create the cinema of ideas which can synthesize both emotional and intellectual elements in the filmic composition. In his system of intellectual cinema, the identity of image and thought externalizes the sensory-motor unity of nature and man along the ascending spiral of centrifugal force of the film. Indeed, in both theory and practice, Eisenstein firmly argues that nature not only provides basic laws for the organic composition of the film, but also expresses itself in the form of the whole which brings out the experience of totality in the film text, the audience, and surely Eisenstein himself.

This paper has been presented the hydrodynamic effect by the journal speed, eccentricity and source positions in order to overcome the defects of air bearing such as low stiffness and damping coefficient. Choosing the two row source position of air bearing is different from existed investigations in the side of pressure distribution of air film because of the high speed of journal and the wedge effects by the eccentricity. These optimal chooses of the two row source positions enable us to improve the performance of the film reaction force and loading force as making the high speed spindle. In this paper, The pressure behavior in theory of air film according to the eccentricity of journal and the source positions analyzed. The results of investigated characteristics may be applied to precision devices like ultra-precision grinding machine and ultra high speed milling.

Experiment on the modal balancing of a flexible rotor supported on two kinds of fluid film bearings is performed to verify the modal balancing theory. The fluid film bearings are a tilting pad bearing and a two axial grooved journal bearing. One is inherently stable, but the other is not. The experimental result shows that the modal balancing method is effective for balancing of a high speed flexible rotor system. Besides, the critical speeds and mode shapes measured experimentally are in good coincidence with the results of rotordynamic analysis. Oil whip, which is the instability phenomenon due to fluid film force, is also observed during the experiment.

Lacan's Identification theory has been applied to various cultural genres such as literature, film, media so on. Especially, Identification theory in Film Theory gives game researchers who try to apply identification theory to the game, a concrete base. This paper aims to explain the gamer's action through identification theory. Thus, we divide identification into the level of the gamer's point of view and that of the character in game text. While point-on-view of identification, the primary identification, in film has been explained that the audience identifies with camera's point-of view, in game one identifies with various point-of-views. There are two aspects of Identification of characters in game. First, gamers identify themselves with moving images on screen. Second, They identify with the roles given to themselves. The factors which allow them identification are suppression of false statement system, interpolation and process of selection, arrangement, a cursor, colours on screen.

Radioactive iodine is a representative fission product to be quantified for the safety assessment of nuclear facilities. In integral severe accident analysis codes, the iodine behavior is usually described by a multi-physical model of iodine chemistry in aqueous phase under radiation field and mass transfer through gas-liquid interface. The focus of studies on iodine source term evaluations using the combination approach is usually put on the chemical aspect, but each contribution to the iodine amount released to the environment has not been decomposed so far. In this study, we attempted the decomposition by revising the two-film theory of molecular-iodine mass transfer. The model involves an effective overall mass transfer coefficient to consider the iodine chemistry. The decomposition was performed by regarding the coefficient as a product of two functions of pH and the overall mass transfer coefficient for molecular iodine. The procedure was applied to the EPICUR experiment and suppression chamber in BWR.

This research is a study of the documentary film entitled "Korean War." My research focuses on the collective trauma and amnesia of the Korean War among the people of the U.S. in an effort to understand ongoing tensions between the U.S. and the two Koreas, both North and South. A study of the film also gives a way to read the hidden meaning of the film through deconstructing the film with Peircian semiotics, and scrutinizing its artistic choices of visual language. This study provides a review of the theory of trauma. It also gives insight into understanding the perceptions of the Korean War in the U.S.

Numerical calculation for temperature dependence of galvanomagnetic properties of thin bismuth films is pursued. The quasi-two dimensional system is treated in the perturbation formalism of previous study, where realistic screened potential due to impurity is assumed to be the only scattering channel. The potential is separated into pure two dimensional part and the remaining presumed perturbation part. Relaxation time and mobilities for both electron and hole are evaluated, then temperature dependence of the Hall coefficient and magnetoresistance is obtained. The broad minimum of magnetoresistnace is manifested, and the interpretation under the kinetic theory is made. Thickness dependence of the quantities are also shown, which are in good agreement with the expected quantum size effect.
