This study analyzed the characteristics of masculineness reproduced in Korean cop films and their deep meaning, mainly in the 2010s. This analysis work will be a work that embodies the masculine ideal type and true masculinity recognized in Korean society. Also, through this, we will be able to approach the ideals and operations of Korean society. As a result, Korean cop films are mysteriously obsessed with masculinity and masculinity behavior through the main character in the film, which shows off masculinity with mental and physical superiority. Korean cop films also show a desire for patriarchal normality through an ending that shows the moment of masculine recovery through the physical victory of a rough and strong man. And the Korean cop film includes the claim that the implementation of social justice requires the existence of masculineness, which is essential, and that the implementation of social justice must be sacrificed to some extent.

With the deepening cooperation between China and South Korea in the field of film, the ways of cooperation between China and South Korea are becoming more and more diversified. "One text, two productions" film cooperation mode refers to the filmmakers of two countries sharing script resources, using the same script to create films separately. South Korean Extreme Job(극한직업) and Chinese Lobster cop(龙虾刑警) are the products of this cooperation model. The scripts of the two films originated from the China and South Korea story joint development plan(중한시나리오공통개발프로젝트) in 2015. After winning the award, the script were filmed by Korean and Chinese filmmakers. Filmmakers in two countries adapted the script to different degrees according to their respective cultural backgrounds and aesthetic characteristics. The film cooperation mode of "One text, two productions" promotes the development of transnational cooperation and opens up a new way of film cooperation.

In general a thermoelectric cooler (TEC) consists of a series of P type and N type thermoelectric materials sandwiched between two wafers. When a DC current passes through these materials, three different effects take place; Peltier effect, Joule heating effect and heat transfer by conduction due to temperature difference between hot and cold plates. In this study we have developed a micro TEC using $Bi_2Te_3$ (N type) and $Bi_{0.5}Sb_{1.5}Te_3$ (P type) thin films. In order to improve that performance of a micro TEC, we made 10 um height TE legs using special PR only for lift-off. We measured COP (coefficient of performance) and temperature difference between hot and cold connectors with current.

Coptp films with the additive elements (X=Fe, Mn) of varying concentrations were prepared by in-situ electrodeposition, to tailor their magnetic properties. Alloys of CoPtP-X (X=Fe, Mn) were synthesized by changing the solution concentrations of Fe and Mn for electrodeposition. In the electrodeposited CoFePtP alloys, preferred orientation of the electrodeposited films changed from hexagonal (001) to (100) direction with increasing iron contents as revealed by X-ray diffraction, and these films exhibited various magnetic properties ranging from a typical hard magnetic to a soft magnetic property in accordance with microstructural variations. In the case of Mn addition, excellent hard magnetic property was observed at a specific Mn concentration of 0.0126 M in the electrolyte, with the coercivity of 4630 Oe and squareness of 0.856 and this was attributed to the fact that magnetization easy-axis (hexagonal c-axis) coincides with the preferred growth orientation of the film confirmed by transmission electron microscopy.

The mort commonly available substrate material is glass in the display fibrication process. However, glass is not desirable due to its heaviness and fragility. Recently, plastics such polysulfone (PSF), polyethesulfone (PES), polycarbonate (PC), polyethylene terephthalate (PET) and cyclic olefin polymers (COP) have been investigated to replace glass as a substrate material for display fibrication. Plastic substrates are advantageous in that they are lightweight, huh impart resistance, flexibility, and ability for roll to roll manufacturing process. But many plastics have poor chemical resistance in organic solvent. The chemica resistance is also lequired because they are exposed to solvents for various chemical treatments din the manufacturing process. So, we have an interest in the chemical modification of PSF to improve chemical resistance. We introduced crosslinkable imide moieties using chloromethylation method for the modification of PSF which could be overcome above shortcomings for display substrate based on plastic film. We prepared the cross-linked polysulfone films which were represented chemical resistance in HeOH, THF, DMSO and NMP. The thermal properties were measured by TGA, DSC and TMA. As the results, we have confirmed to enhance of the thermal property. They had low coefficient of thermal expansion (CTE) which decreased to 15% and had increased $T_g\;from\;180^{\circ}C\;to\;252^{\circ}C$. Cross-linked polysulfone films with imide side-chain had good optical properties and chemical resistance so that they could be used as flexible display substrate.
