The paper presents extensive survey and review of experimental and analytical researches on fluid film bearings and squeeze film dampers (SFDs) for turbomachinery available in open literature (major archival international journals) published recently (2018 and 2019 only). Over 60 published research works are reviewed based on the research topics and objectives, the types of bearings, size of bearings, and main design parameters with a brief summary of experiments and/or predictions in each work. Some important findings and general observations about the experimental and/or predictive data are also presented. There are several major trends observed throughout the survey. A large portion of the papers focuses on bearing surface textures and effect of operating and assembly conditions on static and/or dynamic forced performances, as well as bearing surface roughness and wear patterns. Researches on geometry of orifices and recesses in hydrostatic (or hybrid) bearings, as well as bearing system stability predictions using thermohydrodynamic analysis and computational fluid dynamics (CFD), are considered as significant topics. Studies on SFDs mainly focus on experimental identification of force coefficients for various SFD geometries and sealing conditions. Reliable experiments of fluid film bearings and SFDs along with the development of experimentally benchmarked predictive tools enable reinforcement of the path for reliable implementations of the bearing components into high performance rotating machinery operating at extreme and harsh conditions. The extensive list of sources of recent experiments in the available open literature is a welcome addition to the analytical community to gauge the accuracy of predictive tools.

Drying process in the cylindrical thin film layer of sludge with the thickness less than a few millimeters has been investigated. Thin film drying is specially designed and used to dry the viscous materials like sewage sludge. The thin film layer of sludge is dried on the metallic cylindrical surface through which thermal energy is supplied to the layer during drying. The wall temperature is assumed to be constant during drying in the present study for the simplification. In order to solve the equations, the mass transfer rate on the drying surface should be determined. The mass flux of evaporated water vapor on the surface is estimated with the formulation given in the literature. The effect of some physical parameters on drying has been examined to figure out the drying characteristics of the sludge layer.

An outsider's perspective is often illuminating and enlightening, as he or she perceives the world differently from us, and sees things that insiders tend to miss. While an outsider's views are fresh and penetrating, an insider's vision is often banal and myopic. Although outsiders' perspectives may not be quite right at times, they always shed light and provide insight, allowing us to reevaluate the conventional interpretations of our literature and folktales. In order to prevent our own understanding and knowledge from growing stale and narrow-minded, we should endeavor to consider outsiders' opinions and view all things from multiple angles. When reading literary or cultural texts, therefore, we need to read through others' eyes because it provides alternative perspectives. And we should learn to co-exist with others and see things from others' eyes. In his celebrated novel, My Name Is Red, Orhan Pamuk, the Turkish Nobel Laureate, explores the themes of clashes between the East and the West, the young and the old, and conservatism and radicalism. The confrontation between the stubborn defenders of tradition and the self-righteous innovators ultimately results in bigotry, hatred and murder. As Pamuk aptly perceives in his novel, the inevitable outcome of such uncompromising conflict is degradation of humanity and annihilation of human civilization. That is precisely why we need to embrace others who are different from us and learn to look through others' eyes. Sometimes, we fear other voices and different perspectives. As the movie "The Others" suggests, however, there is no reason for us to be afraid of others.

The copper film coated by Sn is often used in various applications such as LCD, Mobile Phone and etc. Especially, when the film is used as tape carrier package(TCP) of LCD panel, the film is repeatedly applied by mechanical or(and) thermal stress and then is often failed. Therefore, to guarantee the reliability of the electrical devices using the film, the tensile and fatigue characteristics of the film are important. In this study, to obtain the tensile and fatigue characteristics of the film, the specimen was fabricated by etching process to make a smooth specimen of 2000 ${\mu}m$ width, 8000 ${\mu}m$ length and 15.26 ${\mu}m$ thickness. The 2 kinds of specimen were fabricated by other manufacturing process. These specimens had values of Young's modulus(80.2GPa) lower than literature values(108${\sim}$145GPa) for bulk values, but had high values of the yield and ultimate strength as 317MPa and 437MPa, respectively. And fatigue test of load-control with 20Hz frequency was performed.

Zhang yimou's film "the shadow" adopts a lot of modern literary symbolic content in the story structure. The novel has been greatly modified, abandoning the setting of the original work and making up the historical background of the story, thus completing the discourse practice of aerial literature rather than historical literature. The film expresses the historical story poetically and even writes the personal mind. In this way, the audience's sense of substitution is increased, and a large number of traditional Chinese cultural symbols are adopted visually. In terms of clothing, the most traditional is sought, which advocates loyalty to history, and adds cultural connotation and depth. The audience can feel the bold and unfettered artistic creation spirit of the main creator, as well as the novel and unique visual expression style, which makes his works have both traditional visual perception and modern story content. The combination of traditional vision and modern drama forms a new visual and cultural experience.

Fashion brands communicate with consumers through the use of fashion films that are effective in the delivery of the image. This is because digital media (such as fashion films) are popular and accessible as well as effective in attracting people's attention. The reasons why fashion films have become a new fashion media among many others is becuase they are based on an existing platform. This study will examine offline platforms of fashion film: flagship store, fashion exhibition, and fashion show. The offline platform of a fashion film is a physical space where a fashion film can be exhibited and viewed as a medium that can effectively convey fashion film to consumers. As a research method, the concept of an offline platform of fashion film is established based on a literature review of fashion films and platform that is followed by an empirical case study. The study results show that the offline platform of a fashion film is in the progress of turning into an autotelic space where the consumption of such culture as cinema and theater has become possible.

The purpose of this study is to re-read the film of Dead Poets Society, specially focused on a feminist view. The film hides the strategy of recovering the traditional Patriarchal Society. At the beginning, the film resists the values of traditional society through John Keating. His unorthodox methods of teaching literature smack against the traditions of Welton Academy. Furthermore, he stresses on "Carpe Diem"—Seize the Day, the romantic values of free thinking, creativity, and individuality. The forces opposing Keating's philosophy are personified by Welton's rigid, old headmaster, Mr. Nolan, and the cruel, stubborn parent, Mr. Perry. Keating's romantic values are failed by their powerful, dominating attitudes. Effected by Keating's philosophy, Neil decides to pursue acting rather than medicine. He conflicts with his strict father. Finally frustrated by his authority, Neil commits suicide. And Keating is accused of inciting the boys to restart the Dead Poets Society, and at last he is fired. Keating and Neil are victimized by the Patriarchal society. Even though the film concentrates male characters at the all boys' school, it reveals the male angle of binary oppositions between men and women, subject and object, activity and passivity, presence and absence. In the film's dramatic conclusion, English class is now being temporarily taught by Nolan, who has the boys read from the very Pritchard essay they had ripped out at the start of the film. It symbolizes the triumph of the traditional logocentric society. However, influenced by Keating's unconventional attitudes, ultimately Welton Academy will be changed as it is embodied in its closing scene.
