The objective of this study is to contemplate both the formation and the aesthetic characteristics of the ballerina look represented in modern fashion by analyzing a ballet costume. The results of this study could be summarized as the following: the ballerina look is formed by ballet costume itself with being stick to or exposing human body line, or by casual dress mixed with a ballet costume; the materials consist of both the major materials for a ballet costume such as silk, chiffon, tulle, lace, or organza, and the usual materials for casual dress: a variety of color such as transparent, pastel etc. is also used with typically used colors like white and black: decoration is basically composed of ruffle, drape, gather and the distinctive accessory like toe shoes, ribbon tape, ankle warmer is used to show a feature of a ballet costume These formative characteristics of the ballerina look presented in modern fashion implies illusory, pure, and hybridity. traits. First, illusion of the ballerina look not only implicitly expresses a womans wish to experience a ballerina's fantastic world, but also recreates woman herself into a ballerina on a stage. Second, purity of the ballerina look makes design look feminine and smooth, which is expressed with girlish taste through materials and colors. Third, hybridity of the ballerina look suggests a standard of a new trend, which is active style, by adding comfortableness and flexibleness to romantic femininity.

The geological CO2 sequestration in underground geological formation such as deep saline aquifers and depleted hydrocarbon reservoirs is one of the most promising options for reducing the atmospheric CO2 emissions. The process in geological CO2 sequestration involves injection of supercritical CO2 (scCO2) into porous media saturated with pore water and initiates CO2 flooding with immiscible displacement. The CO2 migration and distribution, and, consequently, the displacement efficiency is governed by the interaction of fluids. Especially, the viscous force and capillary force are controlled by geological formation conditions and injection conditions. This study aimed to estimate the effects of surfactant on interfacial tension between the immiscible fluids, scCO2 and porewater, under high pressure and high temperature conditions by using a pair of proxy fluids under standard conditions through pendant drop method. It also aimed to observe migration and distribution patterns of the immiscible fluids and estimate the effects of surfactant concentrations on the displacement efficiency of scCO2. Micromodel experiments were conducted by applying n-hexane and deionized water as proxy fluids for scCO2 and porewater. In order to quantitatively analyze the immiscible displacement phenomena by n-hexane injection in pore network, the images of migration and distribution pattern of the two fluids are acquired through a imaging system. The experimental results revealed that the addition of surfactants sharply reduces the interfacial tension between hexane and deionized water at low concentrations and approaches a constant value as the concentration increases. Also it was found that, by directly affecting the flow path of the flooding fluid at the pore scale in the porous medium, the surfactant showed the identical effect on the displacement efficiency of n-hexane at equilibrium state. The experimental observation results could provide important fundamental information on immiscible displacement of fluids in porous media and suggest the potential to improve the displacement efficiency of scCO2 by using surfactants.

The animation film , which became a worldwide sensation with its theme song 'Let it go', did not only rank first in the U.S. box office - it was also the greatest box office hit in the history of Disney animation. Why did , recreated into a musical animation, become a worldwide success and what were the characteristics of its materialized hybrid visual direction technique? In order to look into this, firstly, literature on musicals and animations were studied, and secondly, analysis standards were drawn for musical characteristics of musicals and direction techniques of animations. Thirdly, analyzation and investigation will be conducted on hybrid visual direction techniques based on the research above with as the example. Through this study, it's known that realizes its musical features such as 'exaggerated acting,' 'delivering the meaning of circumstances', 'dramatic expression of emotion' and etc. through animated characters and that its background music is aided by 'narrative features' through its musical composition. Besides, its snow effect through animated VFX composing scenes along with its musical characteristics realizes hybrid image direction. It can be said that image directing effects of musical animations through hybrid grafting and the characteristics of image aesthetics generate public demands worldwide.

Genomic Southern hybridization of Frankia EuIKl strain, a nitrogen fixing symbiont of Elaeagnus umbellate root nodules, with nifH,D of K. pneumoniae as a probe, showed that 3.2 Kb and 5.5 Kb of BamHI fragments and 15 Kb PstI fragment were strongly hybridized with the probe, indicating nifH,D are located on these fragments. Using the same probe, one clone(pEuNIF) was isolated from the genomic library constructed into pWE15 cosmid vector by colony hybridization. The 3.2 Kb and 5.5 Kb BamHI fragments of this clone were hybridized with the same probe and this result corresponds to the genomic Southern hybridization data. However, using nifH of Frankia FaCl strain as a probe, only the 3.2 Kb BamHI fragment showed hybridization signal. Amino acid sequence deduced from nucleotide sequence of 3' terminus of the 3.2 Kb and 5' terminus of the 5.5 Kb fragments showed that the former was highly homologous with that of ArI3 nifD from 182nd to 240th amino acids, while the latter was from 241st to 282nd amino acids. These results show that nifH and partial nifD sequences are located on the 3.2 Kb fragment and residual sequences of nifH on the 5.5 Kb fragment which is contiguous to the 3.2 Kb fragment.

The elution behavior of polystyrenes(PS), polymethylmethacrylates (PMMA), polybutadienes(PB), PS-PMMA(SM) block copolymers and PS-PB star shaped copolymers on the cross-linked polystyrene gels was studied. An interpretation was proposed for the plots of log hydrodynamic volume versus retention volume of solutes in the mobile phases such as tetrahydrofuran, toluene, chloroform, methylene chloride and tetrahydrofuran-cyclohexane mixture. In order to predict the retention of solutes from their physical properties, multiple stepwise regression analysis was applied to obtain the correlation. The distribution coefficients($K_p$) of solute-gel interactions in GPC for homopolymers and PS copolymers were also obtained in terms of network-limited separation mechanism. In the cases of PS and PB, $K_p$ values approach unity, while $K_p$ values for PMMA decrease as MW increase in the good solvent, but in poor solvent, $K_p$ values increase as MW increase. $K_p$ values of PS copolymers are dependent on their MW and composition, therefore, morohology of SM block copolymer is predicted to be random phase.

In this paper, we propose an efficient image processing system to detect and track the movement of specific objects such as patients. The proposed system extracts the outline area of an object from a binarized difference image by applying a thinning algorithm that enables more precise detection compared to previous algorithms and is advantageous for mixed-mode design. The binarization and thinning steps, which require a lot of computation, are designed based on RTL (Register Transfer Level) and replaced with optimized hardware blocks through logic circuit synthesis. The designed binarization and thinning block was synthesized into a logic circuit using the standard 180n CMOS library and its operation was verified through simulation. To compare software-based performance, performance analysis of binary and thinning operations was also performed by applying sample images with 640 × 360 resolution in a 32-bit FPGA embedded system environment. As a result of verification, it was confirmed that the mixed-mode design can improve the processing speed by 93.8% in the binary and thinning stages compared to the previous software-only processing speed. The proposed mixed-mode system for object recognition is expected to be able to efficiently monitor patient movements even in an edge computing environment where artificial intelligence networks are not applied.

This work explores the historical transformation of manual landscape architectural drawings in terms of hybridization to uncover their inherent creative aspect. Landscape architectural drawing has duel functions; namely, scientific instrumentality and artistic imagination, which are relative, interchangeable, and transformable. These characteristics have been embodied in the forms of particular types of drawing, projections, perspective views, and diagrams, which are not so much clearly distinguishable as rather mutually complementary and hybridized. In particular, the pictorial views of plants in the forms of a perspective view or elevation were frequently hybridized to projection drawings of grounds and architectural structures, which is called planometrics. Particular drawing types have often emerged as suitable and thereby dominant forms, depending on the particular historical styles of landscape design. Sixteenth-century Italian Renaissance gardens and seventeenth-century French formal gardens were generally visualized in the form of projections. Eighteenth-century and early nineteenth-century English landscape gardens were frequently represented in a pictorial perspective view. In nineteenth-century America, different drawing techniques such as competition drawing, photography, and map overlay were specialized depending on their respective functions. Twentieth-century American modernists began to explore the diagram to deploy design strategies. In such transformation, however, the planometric, which considers both the ground plane and plant's frontal identities simultaneously and thereby is suitable to landscape design, was frequently used as a hybridization technique. In the mid-nineteenth century, a top view of plants replaced the planometric, and then, in the twentieth century, plants were no longer represented artistically, instead reduced to the forms of standardized flat symbols. The use of instrumental visualizations thereby gradually increased rather than the use of an imaginative representation for landscape architectural drawings.

To improve the optical characteristics and antifouling of anti-reflective coating (AR) films, various AR coating films were prepared by varying the mixing ratio of tetraethylorthosilicate (TEOS)/base and methyltrimethoxysilane (MTMS)/acid hybrid solution. Prepared AR coating films were characterized by UV-Vis spectroscopy, contact angle analyzer, atomic force microscope (AFM), FT-IR and pencil scratch hardness test. In an AR coating film that prepared from the hybrid solution with a 10 wt% MTMS/acid solution, the glass substrate showed an excellent optical property (97.2% transmittance), good antifouling ($121^{\circ}$ water contact angle and $90^{\circ}\;CH_2I_2$ contact angle) and moderate mechanical strength (pencil hardness of 4 H). In particular, it is considered that the good antifouling was due to the well dispersion of the methyl group ($-CH_3$), derived from a small amount of MTMS/acid solution in the hybrid solution, on the substrate surface. From results of the pencil hardness test, the mechanical strength of AR coating film was improved as the content of MTMS/acid solution increased.
