This paper focused on documentaries and for specific places and described the documentary shooting methodology from the perspective of a Cinematographer. 'Old Seoul Station' and 'DSME' (DAEWOO Shipbuilding & Marine Engineering Co., Ltd.) are monumental spaces that reflect the value of Korea modernization and are shared by Koreans' collective memories, unconsciousness, and unique feelings for the place. 'Old Seoul Station' has changed its place identity to a new space called "Culture Station Seoul 284." 'DSME' is a large-scale industrial complex that still functions actively, and it is like an organism that seeks to change according to changes in its industrial structure. and observe and record images of space related to place identity and the people related to it. It shows the construction of staring into a space in a particular place and continuously recording and placing moments of experience, such as the appearance of people working and resting. If it is not recorded through this, it allows us to see intangible narratives related to volatile place identity, and enables specific place experiences through theaters. This study focuses on production theory based on examples of documentary filming methods for these specific places.

The new preparative separation techneque of dihydroquercetin (2, 3-trans-dihdroxy-3, 3', 4', 5, 7-pentahydroxydihydroflavonol) was investigated by liquid chromatography. Also some typical coniferous wood bark were examined for the sources of dihydroquercetin. The good sources of dihydroquercetin were Douglas-fir[Pseudotsuga menziesii] bark and pitch pine [Pinus rigida] bark. There is no dependance the produced place and species dihyroquercetin which is separated by silica-gel column chromatography was taken with white needle-like crystals. This crystals were very stable in the humidity and on the light. It also can stored very long without derivatives.

Various methods have been proposed for the time series prediction. Most of the conventional methods only optimize parameters of mathematical models, but to construct an appropriate functional form of the model is more difficult in the first place. We employ the Genetic Programming (GP) to construct the functional form of prediction models. Our method is distinguished because the model parameters are optimized by using Back-Propagation (BP)-like method and the prediction model includes discontinuous functions, such as if and max, as node functions for describing complicated phenomena. The above-mentioned functions are non-differentiable, but the BP method requires derivative. To solve this problem, we develop ...

This is a study on Sil-Sil and Chun. Sil-Sil is a kind of turquoise. According to its burial place and use its identity was fixed, It was discovered in the Middle-East Asia like Iran and Tibet, Ancient China imported turquoise from these countries,. Korea also imported it in Shilla period. It was the empresses only who had the priviledge of using Sil-Sil for their ornaments such as hair-pins headdresses and combs. Chun was a sort of metal ornaments. Chun required a high-skilled work' and it showed how advanced its skill at that time.

We studied the trend change of failure rate function and uncertainty of residual life function in terms of location of their trend change points. It is shown that the trend change of uncertainty of residual life takes place before the failure rate changes its trend. Like DIFR(IDFR) does not necessary implies IDMRL(DIMRL), we find the fact that DIFR(IDFR) does not always imply IDURL(DIURL) under certain conditions, through the exponentiated-weibull distribution.

At present, information processing by computer is greatly concerned in our society. And robots controlled by computer are much introduced in a factory´s production line and so on, robot abilities develop robot obtain good results. And recently, robots greatly take part in not only limited place, for example a factory and so on, but also general a household. Some robots pleased people, others help humans task. Robots are sure to be great useful in nursing that as regarded our society as questionable. In this situation, we request that robots can take vision like human´s eyes ...

Thermodynamic and electrical functions of aminophenol and anthranilic acid complexes with Mn(Ⅱ), Fe(Ⅱ), Co(Ⅱ), Ni(Ⅱ) and Cu(Ⅱ) were determined. ΔG°, ΔH° and ΔS° were calculated with the help of stability constant values at different temperatures. It was found that the complexing processes have an exothermic nature. The studied complexes behave like semiconductors. The conduction takes place according to hopping mechanism. To show the composition of complexes conductometric and photometric titrations, IR spectra, thermal analysis and X-ray diffraction techniques were employed.

I will present the Sejong Suite, an extensive collection of state-of-the-art high-resolution cosmological hydrodynamical simulations spanning a variety of cosmological and astrophysical parameters, primarily developed for modeling the Lyman-Alpha forest. Adopting a particle-based implementation, we follow the evolution of gas, dark matter (cold and warm), massive neutrinos, and dark radiation, and consider several combinations of box sizes and number of particles. Noticeably, for the first time, we simulate extended mixed scenarios describing the combined effects of warm dark matter, neutrinos, and dark radiation, modeled consistently by taking into account the neutrino mass splitting. Along the way, I will also highlight some new results focused on the matter and flux statistics.

After 1960s, a radical change was taken place in the modern urban theories which were developped by many architects and planners like Ebenezer Howard, Tony Garnier, Le Corbusier, Ludwig Hiberseimer, and Patrick Abercrombie. Many contemporary architects like Kevin Lynch, Aldo Rossi, Christopher Alexander, Colin Rowe, Rem Koolhaas, and Bernard Tschumi have a view that modern urban theories lost their abilities to organize and control new realities so that new urban theories was needed in order to cope with urban problems in the 1960s. In this study, we are to examine contemporary urban theories in comparison with modern urban theories and to clarify the role of discourse of language in its emergence. In consequence we can detect four main themes in the process of transformation from modern urban theories to contemporary urban theories : from functionalism to formalism, from historicism to archeology, from space to placeness, and from hierarchical organization to network. And we can prove that such themes basically depend on the discourse of language.

This article presents a method to calculate the sound radiation of transmission gearbox housing by using Helmholtz integral. Rayleigh integral is used to verify the method. Half-space radiation is considered because the actual gearbox housing is on hard place like concrete. For optimization, orthogonal array is used as a fractional factorial design method. Sound Radiation is calculated with simple source like plate and sphere shape, then actual gearbox BEM model is applied to the method.
