The global small and mid-sized display market is changing from thin film transistor-liquid crystal display to organic light emitting diode (OLED). Reflecting these market conditions, the domestic and overseas display panel industry is making great effort to innovate OLED technology and incease productivity. However, current OLED production technology has not been able to satisfy the quality requirement levels by customers, as the market demand for OLED is becoming more and more diversified. In addition, as OLED panel production technology levels to satisfy customers' requirement become higher, product quality problems are persistently generated in OLED deposition process. These problems not only decrease the production yield but also cause a second problem of deteriorating productivity. Based on these observations, in this study, we suggest TRIZ-based improvement of defects caused by glass pixel position deformation, which is one of quality deterioration problems in small and medium OLED deposition process. Specifically, we derive various factors affecting the glass pixel position shift by using cause and effect diagram and identify radical reasons by using XY-matrix. As a result, it is confirmed that glass heat distortion due to the high temperature of the OLED deposition process is the most influential factor in the glass pixel position shift. In order to solve the identified factors, we analyzed the cause and mechanism of glass thermal deformation. We suggest an efficient method to minimize glass thermal deformation by applying the improvement plan of facilities using contradiction matrix in TRIZ. We show that the suggested method can decrease the glass temperature change by about 23% through an experiment.

With the scaling down of ULSI(Ultra Large Scale Integration) circuit of CMOS(Complementary Metal Oxide Semiconductor)based electronic devices, the electronic devices become more faster and smaller size that are promising field of semiconductor market. However, very narrow line width has some disadvantages. For example, because of narrow line width, deposition of conformal and thin barrier is difficult. Besides, proportion of barrier width is large, thus resistance is high. Conventional PVD(Physical Vapor Deposition) thin films are not able to gain a good quality and conformal layer. Hence, in order to get over these side effects, deposition of thin layer used of ALD(Atomic Layer Deposition) is important factor. Furthermore, it is essential that copper atomic diffusion into dielectric layer such as silicon oxide and hafnium oxide. If copper line is not surrounded by diffusion barrier, it cause the leakage current and devices degradation. There are some possible methods for improving the these secondary effects. In this study, TaNx, is used of Tertiarybutylimido tris (ethylamethlamino) tantalum (TBITEMAT), was deposited on the 24nm sized trench silicon oxide/silicon bi-layer substrate with good step coverage and high quality film using plasma enhanced atomic layer deposition (PEALD). And then copper was deposited on TaNx barrier using same deposition method. The thickness of TaNx was 4~5 nm. TaNx film was deposited the condition of under $300^{\circ}C$ and copper deposition temperature was under $120^{\circ}C$, and feeding time of TaNx and copper were 5 seconds and 5 seconds, relatively. Purge time of TaNx and copper films were 10 seconds and 6 seconds, relatively. XRD, TEM, AFM, I-V measurement(for testing leakage current and stability) were used to analyze this work. With this work, thin barrier layer(4~5nm) with deposited PEALD has good step coverage and good thermal stability. So the barrier properties of PEALD TaNx film are desirable for copper interconnection.

The percentage of watercore occurrence harvested on Nov. 6 (commercial harvest season) was over 80% but fruits seemed not to reach climacteric stage on the basis of ethylene evolution. The occurrence ratio and severity of watercore gradually decreased with the increase of preshipment storage for 2 months. The level of soluble solids did not show a clear tendency during preshipment storage but flesh firmness, fresh weight, and acidity gradually decreased. Although the overall quality of fruit reduced along with the increase of preshipment storage duration after exposure to retail condition at ambient temperature for 1 week, plastic film wrapping (PE 30 um) as well as plastic film wrapping plus ethylene scrubbing had a benefit on keeping freshness of fruit even after retail condition. Waxed fruit showed excellent appearance but browning disorder was developed. Results indicated that moisture barrier such as plastic film wrapping and ethylene removal have a great potential on keeping freshness of fruit during export which required long-term transport under low humidity environment.

Background: The objective of this article is to make some analysis on the process of work and accidents occurring in slaughterhouses, evidenced in the Brazilian documentary film called Flesh and Bone. As such, it was necessary to discuss an alternative theoretical concept in relation to theories about health and safety at work. This alternative discussion focuses on the concepts of biopower and biopolitics. Methods: The use of audiovisual elements in research is not new, and there is already a branch of studies with methodological and epistemological variations. The Brazilian documentary Flesh and Bone was the basis for the research. The analysis of this documentary will be carried out from two complementary perspectives: "textual analysis" and "discourse analysis." Results: Flesh and Bone presents problems related to health and safety at work in slaughterhouses because of the constant exposure of workers to knives, saws, and other sharp instruments in the workplace. The results show that in favor of higher production levels, increased overseas market sales, and stricter quality controls, some manufacturers resort to various practices that often result in serious injuries, disposal, and health damages to workers. Conclusion: Flesh and Bone, by itself, makes this explicit in the form of denunciation based on the situation of these workers. What it does not make clear is that, in the context of biopolitics, the actions aimed at solving these problems or even reducing the negative impacts for this group of workers, are not efficient enough to change such practices.

In the movie market, make-up shows various ways of make up in professional technology as the industry develops. Therefore, it is necessary to analyze the trend of making a movie with a change in the type of movie Regarding the characteristics of makeup in the early days of silent films, the stage makeup was fully used. also in the days of sound films, the realistic and concrete makeup was expressed such as straight makeup, character makeup, Special effects makeup, and digital makeup. With the development of the fourth industry, CGI special effects have become possible not only in the background of movies but also in makeup. In the movie, makeup does not use CGI makeup alone, but it is used in a combination of straight makeup, character makeup, and special effects makeup. That's why a variety of makeup needs to be taught. In the future, the domestic film industry should establish the improvement measures for educating the techniques of prosthetic/digital makeup by securing the sufficient finances to more vitalize the film industry of Korea in domestic/foreign markets.

Recently, as the problem of environmental pollution emerges, various methods of eco-friendly water treatment method are being developed. Polymer membranes, which are currently leading the market, are inexpensive, but have many problems in terms of chemical resistance and durability. Thus, ceramic membrane has been attracted great attention as high-efficiency water treatment due to excellent durability and chemical resistant. In this study, ceramic membranes were developed via pore structure, size control, and surface treatment. The pore size of the membrane was controlled through the formation of $ZrO_2$ and $TiO_2$ coating films. Tape casting and sol-gel process were used to form a ceramic coating film with nanopores on the surface of the membrane. Microstructure analysis of ceramic membrane and pore size analysis of the coating film were conducted and the change of water treatment characteristics was observed.

As the size of market for electric vehicles and energy storage systems grows, the demand for lithium-ion batteries (LIBs) is increasing. Currently, commercial LIBs are fabricated with liquid electrolytes, which have some safety issues such as low chemical stability, which can cause ignition of fire. As a substitute for liquid electrolytes, solid electrolytes are now being extensively studied. However, solid electrolytes have disadvantages of low ionic conductivity and high resistance at interface between electrode and electrolyte. In this study, Li₇La₃Zr₂O₁₂ (LLZO), one of the best ion conducting materials among oxide based solid electrolytes, is fabricated through RF-sputtering and various electrochemical properties are analyzed. Moreover, the electrochemical properties of LLZO are found to significantly improve with co-sputtered Li₂O. An all-solid thin film battery is fabricated by introducing a thin film solid electrolyte and an Li₄Ti₅O₁₂ (LTO) cathode; resulting electrochemical properties are also analyzed. The LLZO/Li₂O (60W) sample shows a very good performance in ionic conductivity of 7.3×10^-8 S/cm, with improvement in c-rate and stable cycle performance.
