The Chinese reports of the 1930s always show propaganda characteristics. First, at the that times the Chinese reports had a clear aim; second, the reports recorded social facts, and a turbulent situation provided right chance for the propaganda; third, the reports really knew how to grasp anopportune moment to pass on their idea . The last , the reports mastered a good propaganda ways.

The purpose of this study was to analyze the features of the avant-garde architecture in the end of the 20th Century based on the ontology as a metalanguage. In view of the results so for achieved, it is possible to say that the thought of becoming, topology, rhizome thought and the Deleuze's concepts of the fold and the event as ever-changing and evolving at any given time are found in the avant-garde architecture, and the introduction of ontological thought into architectural design encourage hopes for a more natural and existential quality in architecture. However, the avant-garde architecture in the end of the 20th century disclosed the limitation in the architectural expression of ontological thought due to the lack of fully understand on ontology. In conclusion, the ontological approach in architecture offers a new morphological methodology and a new way of programming considering the existential aspect of space through the bricoleur's means leaving the ontological meaning of architecture itself.

Dense -20vol.%SiC composite was synthesized by high-frequency induction-heated combustion synthesis(HFIHCS) method within 2 minutes in one step from elemental powder mixture of W, Si and C. Simultaneous combustion synthesis and densification were accomplished under the combined effects of an induced current and mechanical pressure. Highly dense -20vol.%SiC with relative density of up to 97% was produced under simultaneous application of 60MPa pressure and the induced current. The average grain size of was about 5.2. The hardness and fracture toughness values obtained were 1700kg/ and , respectively.

The purpose of this study was to offer the basic data that are necessary for us to seek for the concretized direction of the Korean physical education in the 21st century by comparing the purposes and characteristics of physical education of Korea with th

In this study, bottom-up type powder processing and top-down type SPD (severe plastic deformation) approaches were combined in order to achieve both full density and grain refinement of Al-20 wt% Si powders without grain growth, which was considered as a bottle neck of the bottom-up method using the conventional powder metallurgy of compaction and sintering. ECAP (Equal channel angular pressing), one of the most promising method in SPD, was used for the powder consolidation. The powder ECAP processing with 1, 2, 4 and 8 passes was conducted for 10 and 20 It was found by microhardness, compression tests and micro-structure characterization that high mechanical strength could be achieved effectively as a result of the well bonded powder contact surface during ECAP process. The SPD processing of powders is a viable method to achieve both fully density and nanostructured materials.

In this paper processing and mechanical properties of Al-20 wt％ Si alloy was studied. A bulk form of Al-20Si alloy was prepared by gas atomizing powders having the powder size of 106-145 and powder extrusion. The powder extrudate was subsequently equal channel angular pressed up to 8 passes in order to refine grain and Si particle. The microstructure of the gas atomized powders, powder extrudates and equal channel angular pressed samples were investigated using a scanning electron microscope and X-ray diffraction. The mechanical properties of the bulk sample were measured by compressive tests and a micro Victors hardness test. Equal channel angular pressing was found to be effective in matrix grain and Si particle refinement, which enhanced the strength and hardness of the Al-2OSi alloy without deteriorating ductility in the range of experimental strain of 30％.

In the early twentieth century, many eastern European composers show the pervasive absorption of structural melodic characters of folk sources into more abstract contemporary music idioms. Pitch structure in that century music has become more explicit in recent analytic writings. Scriabin derived his compositional materials from more abstract sources that were identical to those found in the folk sources. Scriabin moved towards an increasingly systematic handing of pitch set constructions. This paper proposes a theoretical model for a study of collection in post tonal music. It is the aim of this paper to focus on collection in Scriabin's Op. 58, Feuillet d'album(1909). His output is often split into three periods. : Op. 1-29, Op. 30-57, and Op. 58-74. Op. 53-58 pieces are of primary importance in Scriabin's transition to atonality. It is precisely between the second and third periods that something very important happened in Scriabin's musical mind. In particu]ar, his Op. 58 was written while Scriabin was composing Prometheus. The composition employs 6-34 : in a sense the piece is a study of the properties of 6-34, with which Scriabin wad the preoccupied. The most famous variety of this chord is known as the Mystic, or also as the Prometheus as it is ubiquitous in that work. It should be emphasized that Scriabin's small pieces stand in a special relationship to his larger works. Thus the links between his last are strong, as will be seen in the course of this paper.
