The $21^{st}$ century is the age when the revolution of digital technology enables two-way communication and when emotional values are emphasized. Thus, it exerts influence on the fashion industry and fashion communication. Along with fashion shows, advertising and displays, many fashion brands have increased the use of fashion films. For that reason, this study examines the characteristics of fashion films made by fashion brands, based on the frame work of persuasion communication. For the research, literature reviews and internet website research were done and films of Chanel, Prada, Kenzo and Alexander Wang were analyzed. The definition and types of fashion films were redefined as terminology varied throughout previous studies prior to analyzing each case. As a result, a fashion film would be redefined as 'a digital image which a fashion brand publishes to consumers for the promotion of brand comprehension'. Also, five fashion film types, 'short film', 'campaign film', 'animation film', 'brand film' and 'show film' were redefined. The analysis provided three communication characteristics: reliability, engagement and intuition. First, reliability is attained when a fashion brand (sender) delivers brand message to consumers (receiver) consistently and unitedly. Second, engagement is attained when the type of fashion film (channel) delivers creative image features such as format, music, video technique to attract consumers' interest. Lastly, intuition is attained when a fashion brand (sender) delivers a message akin to brand identity and deepens consumers' understanding. In addition, this study tried to identify the unique usage tendency of brands that could serve as practice guidelines for other fashion brands.

The r.f. power effect for Pt doping is investigated on structural and electrochemical properties of amorphous vanadium oxide(V$_2$O$_{5}$) film, grown by direct current (d.c.) magnetron sputtering. Room temperature charge-discharge measurements based on a half-cell with a constant current clearly indicated that the Pt doping could improve the cyclibility of V$_2$O$_{5}$ cathode film. Using glancing angle x-ray diffraction(GXRD) and high-resolution transmission electron microscopy (HRTEM) analysis, we found that the Pt doping with 10W r.f. power induces more random amorphous structure than undoped V$_2$O$_{5}$ film. As the r.f. power of Pt target increases. large amount of Pt atoms incorporates into the amorphous V$_2$O$_{5}$ film and makes $\alpha$-PtO$_2$microcrystalline phase in the amorphous V$_2$O$_{5}$ matrix. These results suggest that the semiconducting $\alpha$-PtO$_2$ microcrystalline phase in amorphous matrix lead to a drastically faded cyclibility of 50W Pt doped V$_2$O$_{5}$ cathode film. Possible explanations are given to describe the Pt doping effect on cyclibillity of the amorphous V$_2$O$_{5}$ cathode film battery. film battery.

Transparent TiO$_{2}$ sols were prepared by hydrothermal synthesis to heat Ti precursor solutions, from Ti hydroxides obtained with neutralizing aqueous TiOCl$_{2}$ solutions having various concentrations of NaCI by aqueous NaOH solution, in the autoclave at 120$^{\circ}C$ The photocatalytic abilities of glass beads coated with the sol for gaseous benzene were evaluated. As a result, it was found that due to the increase of brookite phase in TiO$_{2}$ by controlling the concentration of Na ion the optical absorption of TiO$_{2}$ increases toward long wavelength but that in the area of short wavelength becomes relatively low and consequently the photocatalytic performance of TiO$_{2}$ thin film for benzene gas rather decreases, compared to that of composite film of anatase and brookite phases. These results suggest that in order for coated TiO$_{2}$ thin film to have high dissociation performance for benzene gas it is effective to form anatase and brookite phases compositely in TiO$_{2}$.

Lanthanide diphthalocyanines have interesting properties on electrochemical and chemical redox reactions. It is however, difficult to use because of thier short device life. Plasma-polymerization attends to improvement thier device life. Yb-diphthalocyanine ($YbPc_2$) polymer film was deposited in a parallel plate electrodes-type RF plasma reactor. $YbPc_2$ was sublimed into the argon plasma, and polymer film was obtained on a substrate. Radio frequency was constant of 13.56MHz. Pressure of argon gas, sublimation rate of $YbPc_2$ and RF power were variable parameters depending on film quality. Surface of polymer films include a lot of sub-micron order lumps. It was indicated that size of lumps depends on polymerization degree controled by parameters. Size of lumps and polymerization degree are increased with RF power. However, by the high RF power over 40W, polymerization degree is decreased with RF power and surface of film is rough. In condition of RF power is high, polymerization will compete with etching of film. We obtained good films for electrochromic display with RF power of 20W, argon gas pressure of 8.0 Pa and sublimationrate of $1.2 \times 10$ mol/min, and good films for gas sensor with RF power of 30W, argon gas pressure of 10.6Pa and sublimation rate of $1.2 \times 10$ mol/min.

This study analyzed the type of format and content expression of fashion films, from the perspective of promotion and advertisement. For the analysis, a reference research and case study were employed. Our results showed that the format type of fashion films are categorized as movie type; films that convey a story through lines and provide an interesting element as well as artistic value;, video clip films which consist of intriguing sections in a short-length film;, animation type; films that deliver a message through the virtualized world and a created character;, and music video fashion films that use the musical technique to convey how the story of fashion film is structured. The type of content expression of fashion films are divided into direct expression, which exposes the collection of clothes and accessories directly in fashion films;, metaphorical type; which visually delivers the brand image and product;, and the documentary type; that delivers the brand story and historical facts related to the brand. The study on the analysis of fashion films through type of format and content expression shows how fashion brands effectively and strongly promote their products, enhance their brand values, and increase an interest among the customers.

Molecular dynamics simulations were performed to study interface structures between an $Al_2O_3$ crystalline phase and a interface phase of $CaAl_2Si_2O_8$. We calculated atomic structures and excess interface energies in systems with different thicknesses of the interface film. It was found that excess interface energies at first readily decreased with increasing film thickness, but increased for larger thicknesses of more than 2 nm. The excess energies of $Al_2O_3/CaAl_2Si_2O_8$ interfaces exhibit a minimum at a thickness around 1 nm. In this range of film thicknesses, the atoms in the interface film show a short-range ordered structure and slow diffusion rather than the random structure and rapid diffusion expected to an observation of an equilibrium thickness for interface films in ceramics.

In this study, the performance of dye-sensitized solar cells with different thickness of the photelectrode film was simulated by using the electron-diffusion differential model. Through this simulation, the relationships between the thickness of the photoelectrode film and the performances (open-circuit voltage, short-circuit current density, and overall photoelectric-conversion efficiency) of cells were understood and the performances with different thickness of the photoelectrede film were also examined. For considering the refractive index in the liquid electrolyte and exploring the scattering effect of titanium dioxide particles with different sizes using the Mie light-scattering theory, the highest scattering effect of each particles was found out and the optimal size of the titanium dioxide particle was determined for light scattering in the photoelectrode film of dye-sensitized solar cell. Through experiment, the mixed titanium dioxide cell was better than the single titanium dioxide cell and generated a higher overall conversion efficiency because the optimal titanium dioxide particles in the phoelectrode film as light scattering.

In this study, RF magnetron sputtering was used to investigate the relationship between oxygen vacancy and carrier concentration in a GZO film on an amorphous structure. RF power was fixed at 50W and Ar flow was changed on a glass plate to create a thin film at room temperature. The transmittance of Al-adopted amorphous GZO was measured at 85% or higher; therefore, the transmittance was shown to be outstanding in all films. The hall mobility was also shown to be higher at the film showing the high transmittance at a short-wavelength, whereas the optical energy gap was shown to be higher at the film with high oxygen vacancy. The oxygen vacancy at the amorphous oxide semi-conductor increased the optical energy gap while it was not directly involved in increasing the mobility. The oxygen vacancy increases the carrier concentration while lowering the quality of amorphous structure; such factor, therefore affected the mobility. The increase of amorphous property is a direct way to increase the mobility of amorphous oxide semi-conductor.

A ferroelectric $(Bi,La)_4Ti_3O_{12}$ (BLT) thin film fabricated by the pulsed-DC sputtering method was evaluated on a cell structure to check its compatibility to high density ferroelectric random access memory (FeRAM) devices. The BLT composition in the sputtering target was $Bi_{4.8}La_{1.0}Ti_{3.0}O_{12}$. Firstly, a BLT film was deposited on a buried Pt/$IrO_x$/Ir bottom electrode stack with W-plug connected to the transistor in a lower place. Then, the film was finally crystallized at $700^{\circ}C$ for 30 seconds in oxygen ambient. The annealed BLT layer was found to have randomly oriented and small ellipsoidal-shaped grains (long direction: ~100 nm, short direction: ~20 nm). The small and uniform-sized grains with random orientations were considered to be suitable for high density FeRAM devices.
