The paraelectric cubic-to-ferroelectric tetragonal phase transition of the thin Pb(Zr, Ti)$O_3$ (PZT) films grown on MgO(001) substrate was investigated in a series of synchrotron x-ray scattering experiments. As the thickness of the film decreases the transition temperature and the amount of the tetragonal distortion were decreased continuously Different from only the c-domains were existent in the thinnest 25nm thick film. Based on this we propose a model for the domain structure of the tetragonal PZT/MgO(100) film that is very different from the ones suggested in literature. We attribute the suppression of the transition to the substrate field that prefers the c-type domains near the interface and suppresses the tetragonal distortion to minimize the film-substrate lattice mismatch.

The purpose of this study was to review and establish the two concepts of art film and artistic expression in Prada fashion films, through a literature review of domestic and international case studies, as a form of luxury branded content, Prada fashion films are considered to artistic film genre. For the study, aesthetic expression in art films as discussed in the previous research was divided into four types. The study method was to review fashion / art films from the founding of YouTube, specially, works that used digital images from Thunder Perfect Mind, which was introduced in Prada in 2005, to Nylon Farm in 2018, stylistic features were searched by film. In addition, for this study, fashion film was analyzed based on the typology of art films. The following conclusions regarding artistic expression were drawn from this study : First, the Prada fashion films represent a transition to advanced art through a conceptual approach. Second, the causal relationships personality psychology can be cited through the disturbed and fragmented narrative lines. Third, the films help people identity Prada's aesthetics by humanizing the luxury brand. Fourth, the films are a feature of serialization.

The purpose of this study is to examine emerging trends in fashion films and the impact of COVID-19 through analysis of Prada films produced before and after the initial spread of the COVID-19 pandemic. We selected 40 cases occurring prior to the pandemic, from June to December 2019, and 21 cases occurring since the outbreak, from June to December 2020. To identify relevant trends, we conduct a literature review and examine a range of case studies. First, travel restrictions and confronting activities currently inhibit production. Through our case study analysis, we identify nineteen cases in between before and after COVID-19. Secondly, Prada can be seen to mainly produce episodes and promotional films. Additionally, it develops content showcasing brand values in environmental, cultural, creative, and sport-related fields; intended audiences extend beyond the realm of fashion. Thirdly, a new film category began to develop after the outbreak of COVID-19, namely, narrative films utilizing virtual interactions. According to our analysis results, we expect film production that is increasingly facilitated by virtual communication, technology utilization, and online platforms to continue even after the resolution of COVID-19. New film categories will emerge, and we predict that the gap between the number of cases before and after COVID-19 will narrow.

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.

In this present work, the effect of hole shapes, orientation and hole arrangements on film cooling effectiveness has been carried out. For this work a flat plate has been considered for the computational model. Computational analysis of film cooling effectiveness using different hole shapes with no streamwise inclination has been carried out. Initially, the model with an inclination of $30^{\circ}$ has been verified with the experimental data. The validation results are well in agreement with the results taken from literature. Five different hole shapes viz. Cylindrical, Elliptic, Triangular, Semi-Cylindrical and Semi-Elliptic have been compared and validated over a wide range of blowing ratios. The blowing ratios ranged from 0.67 to 1.67. Later, orientation of holes have also been varied along with the number of rows and hole arrangements in rows. The performance of film cooling scheme has been given in terms of centerline and laterally averaged adiabatic effectiveness. Semi-elliptic hole utilizes half of the mass flow as in other hole shapes and gives nominal values of effectiveness. The triangular hole geometry shows higher values of effectiveness than other hole geometries. But when compared on the basis of effectiveness and coolant mass consumption, Semi-elliptic hole came out to give best results.

Surface and mechanical properties of thin films with submicron thickness was characterized by nanoindentation with Berkovich and Vickers tips, and scanning probe microscopy. Nanoindention was made in a depth range of 15 to 200 nm from the surface by applying tiny force in a range from 150 to $9,000 \mu$N. Stiffness, contact area, hardness, and elastic modulus were determined from the force-displacement curve obtained. Reliability was first tested by using fused quartz, a standard sample. Elastic modulus and hardness values of fused quartz measured were the same as those reported in the literature within two percent of error. Mechanical properties of ITO thin film were characterized in a depth range of 15∼200nm. As indentation depth increased, elastic modulus and hardness decreased by substrate effect. Ion beam deposited DLC thin films were indented in a depth range of 40∼50 nm. The results showed that the DLC thin film using benzene and bias voltage 0∼-50 V has elastic modulus and hardness value of 132 and 18 GPa respectively. Pure DLC thin films showed roughnesses lower than 0.25 nm, but silicon-added DLC thin films showed much higher roughness values, and the wavy surface morphology.

The essay explores the narrative structure of the classical Chinese feature animation, (a.k.a. Da Nao Tian Gong, 1964). The film is presented with a modular structure which is quite unique compared with the storytelling in feature animated films from other cultures, but could be connected with the tradition narrative structure in Chinese Zhanghui style novels in Ming and Qing Dynasty. By relating the original text of the story, the 16th century novel Journey to the West (a.k.a. Xi You Ji), with the film , the essay addresses the question of how the narrative tradition in Chinese classical literature influenced the Uproar in Heave for its segment narrative structure, character driven storytelling strategy and mirrored repetitive 2 plot lines. The subject of this essay is even more significant after the restored 3D version of was re-released in the spring of 2012 and became one of the best-selling animated feature film in the history of the country.

In this paper, we propose a numerical method to model temperature dependent threshold voltage shift observed in metal oxide thin-film transistors (TFTs). The proposed model is then implemented in AIM-SPICE circuit simulation tool. The proposed method consists of modeling the well-known stretched-exponential time dependent threshold voltage shift and their temperature dependent coefficients. The outputs from AIM-SPICE tool and the stretched-exponential model at different temperatures in the literature are compared and they show a good agreement. Since metal oxide TFTs are the promising candidate for flat panel displays, the proposed method will be a good stepping stone to help enhance reliability of fast-evolving display circuits.
