  • The objective of this study is to investigate the flexural behavior of reinforced concrete columns confined by lateral ties. This test was carried on the twelve reinforced concrete columns, 200$\times$200$\times$800mm size. objected to flexure and constant axial loads. The main variables are concrete strength, the configuration of lateral ties and the amount of lateral ties. Test results indicated that steel configuration plays an important role in column behavior, and a proper configuration of lateral ties can be more ductile than the reduce of the space of lateral ties. By this experiment, the ductility of high-strength concrete columns designed on A.C.I Code is not adequate, and are concluded that the design of high-strength concrete column is executed by more lateral ties under high axial loads.

  • Research and development studies in internal combustion engines are set on a turning point due to requirements mostly purify the polluted environments. Naturally, basic studies concerned about engines are objected to elucidate formation mechanism of harmful matters, such as nitric oxide $(NO_x)$ and particulate matters. And for diesel engines, phenomenon in combustion chambers are analyzed in several approach ways in order to obtain detail understandings in closed and hardly observing space. In this article. it is discussed that the formation mechanism of diesel fuel sprays, mostly non-evaporating free diesel sprays. From that it would be promoted some new innovations in internal combustion engines of next generation.

  • After 1995, as a part of national geographic information system project, there are a lot of researches about combinations and connections of national geographic information system. However, systematic standard for combinations and connections of geographic information is uncertain, and each organization has different identification system which leads to difficulties in connection of geographic information system. This study suggests repeating method about geographic information objects to grant UFID based on national standards of geographic information system, and analyzes the repeating rate.

  • Many studies on internal data expression to process logic functions efficiently on computer have been doing actively. In this paper, we propose an efficient logic function manipulation system made on the Objected-Oriented manner, where Binary Decision Diagrams(BDD's) are adopted for internal data espressionof logic functions. Thus it is easy to make BDD's presenting combinational problems. Also, we propose a method of applying filtering function for reducing the size of BDD's instead of attributed bits, and add it to the mainpultion system. As a resutls, the space of address is expanded so that the number of node that can be used in the mainpulation system is increased up to 2/sup 27/. Finally, we apply the implemented system to One-Shot state assignment problems of asynchronous sequential circuits and show that it is efficient for the filtering method to reduce the size of BDD's.

  • This study set out to figure out the tendencies of the staff members participating in the space design of Blade Runner and compare and analyze its set and location characteristics with its narrative based on Gilles Deleuze' Simulacrum, one of the basic theories of Post modernism, thus identifying the characteristics of postmodern space inherent in it. The findings were as follows: first, the spaces in a Late modernism tendency in Blade Runner seem to have been created by the cinematic imagination of Syd Mead and Douglas Trumbull rather than being influenced by the old Late modernism architecture. Second, the postmodern spaces of the movie were designed to depict a more realistic future by reinforcing the old ornamental elements or adding the mechanical aesthetics of Late modernism based on a prediction of future cities. Third, the characters representing Late modernism and Post modernism in the narrative of the movie embrace the tendencies of the parties objected by Model and Simulacrum in the scenes where they deny the tendencies of the spaces to which they belong, thus exhibiting a dual trend. Fourth, the dual narrative of Model and Simulacrum holds duality even in the space and architecture of the movie, which is the reason why the movie chose postmodern spaces reflecting historical contexts instead of inner spaces in the tendency of minimalism, which was in vogue when SF movies were made those days. Finally, the spaces of the movie can be categorized according to the Late modernism and Post modernism tendencies from the perspective of the 1980s and be understood to show the architecture and space of future Post modernism feasible through the layering of historicity, locality, and mechanical aesthetics from ancient Maya to a future city in Los Angeles, the background of the movie, from the perspective of 2019.

  • This study* 1) historically considered the meaning of light which has frequently wed as the subject of artistic expression since Renaissance, in order to grasp an artistic atmosphere about light and rays before the allusion of Rayonism. non it inspected closely the course of changes of light as a result of historic circumstances and intended to understand how Rusian Rayonism of the 20th, which maintained these effects of light more rationally, had an influence on modern fashion. It was created by Mikhail Larionov and developed by his wife, N. Goncharova. The main special feature of Rayonism wag the crossing of reflected ras, emerging from various objects. Most of these things depended on line and color. Re purpose of Rayonism paintings was to create a new space from arising from which reflected rays from various selected objected crossed one another. Namely, artists maintained that they should give up various objects of visible world and express rays which were reflected objects and crossed in complex. Rayonists were affected by Cubism and Futurism and came to fake an interest in relations whose rays of parallel or convergent color made, also in expression of themes. Since that, Rayonsim affected Supermatisme and Constructivism. Re pursuit of light and rays from the 19th until the early 20th came to appear in fashion as well as in art as it was. As Rayonists created a new space from which reflected rays from selected objects crossed one another, they used line and color as the main techniques of expression. in this way the attempt which intended to express rays, using itself of the line and color, appeared as futile design of tots of designs like Donna Karan, Cianni Versace and Rococo Barocco and so on of Modem fashion. This was designed for essential elements of pure art to express the new aestheic consciousness through fashion.

  • Advanced Life Support Systems(ALSS) are being studied to support human life during long-duration space missions. ALSS can be categorized into four subsystems: Crew, Biomass Production, Food Processing and Nutrition, Waste Processing and Resource Recovery. The System Studies and Modeling (SSM) team of New Jersey-NASA Specialized Center of Research and Training (NJ-NSCORT) has facilitated and conducted analyses of ALSS to address systems level issues. The underlying concept of the SSM work is to enable the effective utilization of information to aid in planning, analysis, design, management, and operation of ALSS and their components. Analytical tools and computer models for ALSS analyses have been developed and implemented for value-added information processing. The results of analyses heave been delivered through the internet for effective communication within the advanced life support (ALS) community. Several modeling paradigms have been explored by developing tools for use in systems analysis. they include objected-oriented approach for top-level models, procedureal approach for process-level models, and application of commercially available modeling tools such as $MATLAB^{R}$/$Simulink^{R}$. Every paradigm has its particular applicability for the purpose of modeling work. an overview is presented of the systems studies and modeling work conducted by the NJ-NSCORT SSM team in its efforts to provide systems analysis capabilities to the ALS community. The experience gained and the analytical tools developed from this work can be extended to solving problems encountered in general agriculture.
