Dans l'histoire du $th{\acute{e}}{\hat{a}}tre$ $cor{\acute{e}}en$, la position de Chae yoon-il est $tr{\grave{e}}s$ $particuli{\grave{e}}re$. Il a $consacr{\acute{e}}$, dans ses $carri{\grave{e}}res$ de la mise en $sc{\grave{e}}ne$, toute son ${\acute{e}}nergie$ au $th{\acute{e}}{\hat{a}}tre$ sans jamais $fl{\acute{e}}chir$ contre le pouvoir dictatorial. Un critique a dit que son $th{\acute{e}}{\hat{a}}tre$ est semblable au $th{\acute{e}}{\hat{a}}tre$ de la $cruaut{\acute{e}}$. Pourtant, dans la mesure $o{\grave{u}}$ il respecte le texte dramatique, et que son $th{\acute{e}}{\hat{a}}tre$ a des tendances de la politique et qu'il oriente l'engagement du spectateur, il est certain que son $th{\acute{e}}{\hat{a}}tre$ est loin du $th{\acute{e}}{\hat{a}}tre$ de la $cruaut{\acute{e}}$. Ses $proc{\acute{e}}d{\acute{e}}s$ de la mise en $sc{\grave{e}}ne$ sont $tr{\grave{e}}s$ divers et il n'y a pas de $coh{\acute{e}}rences$ au niveau des styles dramatiques. $Malgr{\acute{e}}$ cela, nous pouvons trouver son $originalit{\acute{e}}$ de la mise en $sc{\grave{e}}ne$ dans la rencontre avec Lee hyun-wha. Le metteur en $sc{\grave{e}}ne$ ${\acute{e}}tablit$ son $esth{\acute{e}}tique$ $th{\acute{e}}{\hat{a}}trale$ en montant sur $sc{\grave{e}}ne$ de cinq $pi{\grave{e}}ces$ de Lee hyun-wha. Alors, en effet qu'est-ce que $l^{\prime}esth{\acute{e}}tique$ de la mise en $sc{\grave{e}}ne$ de Chae yoon-il produite par les ${\oe}uvres$ $th{\acute{e}}{\hat{a}}trales$ de Lee hyun-wha? Dans les $pi{\grave{e}}ces$ de Lee hyun-wha, il y a beaucoup de codes symboliques de la violence sexuelle comme le sadisme et le masochisme. L'implusion sexuelle $cach{\acute{e}}e$ dans le subconscient des personnages s'entrecroise avec le $m{\acute{e}}canisme$ du pouvoir politique. Alors, les abus sexuels et les mauvais traitements sur le corps deviennent une sorte de torture. L'expression cruelle des langages $sc{\acute{e}}niques$ n'est autre que la $r{\acute{e}}volte$ contre la $r{\acute{e}}alit{\acute{e}}$ actuelle de la politique. Son $th{\acute{e}}{\hat{a}}tre$ de torture est donc une sorte de $m{\acute{e}}canisme$ de la catharsis pour dissiper le cauchemar et l'inconscient noir. La fantasie sexuelle construite par le monde inconscient de l'auteur dramatique $s^{\prime}{\acute{e}}panouit$ dans le $th{\acute{e}}{\hat{a}}tre$ de Chae yoon-il qui $r{\hat{e}}ve$ toujours l'esprit de la $libert{\acute{e}}$. Une des convictions dramatiques du metteur en $sc{\grave{e}}ne$, c'est que le $th{\acute{e}}{\hat{a}}tre$ tout d'abord doit ${\hat{e}}tre$ choquant. Il dit : "l'art doit ${\hat{e}}tre$ ${\grave{a}}$ la fois ${\acute{e}}mouvant$ et bouleversant. Cependant, dans la mesure $o{\grave{u}}$ le film ou la $t{\acute{e}}l{\acute{e}}vivion$ fait aujourd'hui une vive impression aux spectateurs, la part $donn{\acute{e}}e$ au $th{\acute{e}}{\hat{a}}tre$ est le choc." Pour donner le choc aux spectateurs, le style de la torture est $tr{\grave{e}}s$ utile. $L^{\prime}esth{\acute{e}}tique$ $th{\acute{e}}{\hat{a}}tral$ du metteur en $sc{\grave{e}}ne$ respecte essentiellement l'intention de l'auteur. $N{\acute{e}}anmois$, le respect sur l'original ne se $d{\acute{e}}range$ pas $l^{\prime}interpr{\acute{e}}tation$ de son propre $id{\acute{e}}e$. Dans l'insistance de la torture, l'analyse rituelle sous la base du choc, il projecte le symbole $arch{\acute{e}}typal$ sur $sc{\grave{e}}ne$. Bien $s{\hat{u}}r$, il renforce le $caract{\grave{e}}re$ de la politique dans le $th{\acute{e}}{\hat{a}}tre$ de torture pour inviter des spectateurs de l'engagement. D'ailleurs, il y a l'aspect d'absurde dans le $th{\acute{e}}{\hat{a}}tre$ de torture qui insiste des violences ${\grave{a}}$ travers les langages $sc{\acute{e}}niques$ comme le $m{\acute{e}}tal$ froid, parce que le metteur en $sc{\grave{e}}ne$ $consid{\grave{e}}re$ que $l^{\prime}{\hat{e}}tre$ humain vit dans l'absurde.

Bio-heavy oil for power generation is a product made by mixing animal fat, vegetable oil and fatty acid methyl ester or its residues and is being used as steam heavy fuel(B-C) for power generation in Korea. However, if the fuel supply system of the fuel pump, the flow pump, the injector, etc., which is transferred to the boiler of the generator due to the composition of the raw material of the bio-heavy oi, causes abrasive wear, it can cause serious damage. Therefore, this study evaluates the fuel characteristics and lubricity properties of various raw materials of bio-heavy oil for power generation, and suggests fuel composition of biofuel for power generation to reduce frictional wear of generator. The average value of lubricity (HFRR abrasion) for bio-heavy oil feedstocks for power generation is $137{\mu}m$, and it varies from $60{\mu}m$ to $214{\mu}m$ depending on the raw materials. The order of lubricity is Oleo pitch> BD pitch> CNSL> Animal fat> RBDPO> PAO> Dark oil> Food waste oil. The average lubricity for the five bio-heavy oil samples is $151{\mu}m$ and the distribution is $101{\mu}m$ to $185{\mu}m$. The order of lubricity is Fuel 1> Fuel 3> Fuel 4> Fuel 2> Fuel 5. Bio-heavy oil samples (average $151{\mu}m$) show lower lubricity than heavy oil C ($128{\mu}m$). It is believed that bio-heavy oil for power generation is composed of fatty acid material, which is lower in paraffin and aromatics content than heavy oil(B-C) and has a low viscosity and high acid value, resulting in inhibition of the formation of lubricating film by acidic component. Therefore, in order to reduce friction and abrasion, it is expected to increase the lubrication of fuel when it contains more than 60% Oleo pitch and BD pitch as raw materials of bio-heavy oil for power generation.

Coin cell is a basic testing platform for battery research, discovering new materials and concepts, and contributing to fundamental research on next-generation batteries. Li metal batteries (LMBs) are promising since a high energy density (~500 Wh kg^-1) is deliverable far beyond Li-ion. However, Li dendrite-triggered volume fluctuation and high surface cause severe deterioration of performance. Given that such drawbacks are strongly dependent on the cell parameters and structure, such as the amount of electrolyte, Li thickness, and internal pressure, reliable Li metal coin cell testing is challenging. For the LMB-specialized coin cell testing platform, this study suggests the optimal coin cell structure that secures performance and reproducibility of LMBs under stringent conditions, such as lean electrolyte, high mass loading of NMC cathode, and thinner Li use. By controlling the cathode/anode (C/A) area ratio closer to 1.0, the inactive space was minimized, mitigating the cell degradation. The quantification and imaging of inner cell pressure elucidated that the uniformity of the pressure is a crucial matter to improving performance reliability. The LMB coin cells exhibit better cycling retention and reproducibility under higher (0.6 MPa → 2.13 MPa) and uniform (standard deviation: 0.43 → 0.16) stack pressure through the changes in internal parts and introducing a flexible polymer (PDMS) film.

This study investigated the effects of conventional predrying and modified atmosphere (MA) on the head quality and storability of Chinese cabbage 'Norang' cultivar. Immediately after harvest, heads were predried for 2 days and MA stored in $50{\mu}m$ PE film packages at $4^{\circ}C$. MA packaging restrained Hunter L and b values of Chinese cabbage more effectively than non-packaging during storage at $4^{\circ}C$. But there was little change between the two treatments. Fresh weight decreased less in heads treated with predrying and MA than non-treatment during storage. Predried Chinese cabbage heads kept a high level of soluble solids in 4 weeks of storage, while non-packaging maintained high contents of soluble solids for 6 weeks of storage period. Chinese cabbage heads contained 7.0 mg/gFW glucose, 6.3 mg/gFW fructose, and 0.6 mg/gFW sucrose as major soluble sugars at harvest. The content of sugars decreased immediately after predrying and increased steadily after 2 weeks storage. It was found inappropriate to assess head quality of Chinese cabbage by investigating was investigated by Hunter a, firmness, dry matters content, pH, and soluble sugars after predrying and MA package. Marketability of Chinese cabbage was lost when heads were stored at room temperature in 2 weeks. It showed poor appearance of heads stored at $4^{\circ}C$ in 7 weeks. Decay occurred in Chinese cabbage stored in MA under excessive relative humidity. Predried head showed good appearance during storage at $4^{\circ}C$ for 7 weeks. As a result, Chinese cabbage heads can be successfully stored for at least 7 weeks with predrying and MA storage.

The efficiency and applicability of the solid phase extraction disk method in a ²²⁶Ra analysis were examined by the gamma ray spectrometer (GRS) method using a Marinelli beaker and the liquid scintillation counter (LSC) method for groundwater. The recovered ²²⁶Ra, which was filtered by the solid phase extraction disk, was analyzed using gamma ray spectrometer The disks, which were pretreated for caulking the daughter nuclide, were sealed with polyethylene film. Distilled water was used for the blank value of the ²²⁶Ra activity. The recovery values of ²¹⁴Bi and ²¹⁴Pb in the solid phase extraction disk, which used ²²⁶Ra standard material, were 80% (295.21 Kev) and 104% (351.92 Kev), respectively, which were higher than 75% determined by the LSC. The injection of nitrogen gas into the measuring chamber reduced the interference values by about 10%. The detection limits of the ²²⁶Ra activity in a blank sample of 5 L were 0.17~0.40 pCi/L after 80,000 seconds of measuring time. The relationship of the ²²⁶Ra activity in the solid phase extraction disk method and in the LSC method in seven groundwater samples showed a correlation coefficient value 0.987, which implies the applicability of the solid phase extraction disk method. The results showed that ²²⁶Ra activity in groundwater using the solid phase extraction disk method has the following benefits: simple pretreatment, time saving, high recovery values, a low detection limit, and so on. Compared with the LSC method and the GRS method using the Marinelli beaker for the ²²⁶Ra analysis, the solid phase extraction disk method could be useful in groundwater samples with low levels of activities of radionuclides because the method is not restricted by the volume of the sample.

There are many cases that messages of boring contents of most contents with public interests appear on the surface. Audiences don't think these contents are interesting. It is true that animations cannot be generally boring when delivering messages of public interests. was produced to focus on making audiences experience that a global warming story, the boring and textbook contents is interesting. And it was composed by the multiform story to realize narration through audiences' participation by utilizing the characteristics of live windows, not just watching the animation. This paper examines the differences between theaters and live window through the case that was produced and examples which utilized interaction for audiences' participation based on this. It analyzes the differences between environments according to characteristics of places and audiences in the differences between the theaters and live window, examines the examples to utilize interaction focusing on the process that narration is gradually changed as response to user environment design and interaction for unspecified individuals, and suggests direction that animation should move forward as public art based on the results to show the animation in Millano Piazza. According to the characteristics of live windows, the audiences of are people in the streets who are heading for different destinations, not the ones who come to theaters to watch the animation. Showing the animation with narration to them was a new attempt. When it began to show it in Millano Piazza, the audiences were very satisfied with the experiences that the stories were changed as they participated in it by themselves and naturally thought of global warming problems. You cannot know how the message of change people's habits and thoughts for the present, but this attempt was an opportunity that animations play the social role. Many animations are being produced in the world. Most of them are being done to aim at theaters, TVs, and film festivals. They should meet audiences through more various methods. One of them is animations as public art. And can be the new attempt in this sense. And in the future, animations as public art should make efforts to show you interesting experiences that you can share thoughts to be able to live together. As art of various media is changing to the one which considers public interests, animations can be new types of public art by integrating them with various technologies.

Surrealism with the excavation of unconsciousness, seeking for the infinity etc. has established views on aesthetics that conflict traditional western rationalism. The main concern of surrealism is problem of identity and difference. They attempted their own mysterious concept such as 'the marvelous', 'convulsive beauty', 'object chance' etc. These unique views on aesthetics was expressed as various style of art. It is the d$\acute{e}$paysemant that exists one of the typical style in surrealism. D$\acute{e}$paysemant means that objects are taken from be originally place. Therefore, The real world's objects is to leave and change environment from real space as use, ability, meaning of origin. or it is the technique to create surreal illusion that combined to a strange place where relates to extraneous attribute of objects. Namely, objects are newly arranged in expression space. Reconstitutive objects by positioning object over the time and space have given us the marvelous and psychological shock and get unfamiliar meaning and feeling over. This paper is tried to look at the way to use the d$\acute{e}$paysemant which applicated in the media, Especially, focusing on animation. Unlike the other media, animation has its unique artistic characters. First, One of the media characteristics of the animation is creativity images of the hand drawn animation by shooting of frame by frame. The animation image which is created through arrangement obtain life force by unique motility. Works of Norman McLaren and Harry Smith are very interesting that the structural characteristics of the d$\acute{e}$paysemant. It consists with abstract forms and various moving images to let audience the feel characteristics of film. We can experience from these cases, numerous illusion fantasy like change over from creature to inanimate object, space and time, creation and extinction, repetition and metamorphosis etc. One of the main apparat is the emphasis of d$\acute{e}$paysemant in space of frame. In conclusion, d$\acute{e}$paysemant is one of the most characteristic expression technique of surrealism while having inevitable linkage with animation.

A stoichiometric mixture of evaporating materials for $MgGa_2Se_4$ single crystal thin films was prepared from horizontal electric furnace. To obtain the single crystal thin films, $MgGa_2Se_4$ mixed crystal was deposited on thoroughly etched semi-insulating GaAs(100) substrate by the Hot Wall Epitaxy (HWE) system. The source and substrate temperatures were $610^{\circ}C$ and $400^{\circ}C$, respectively. The crystalline structure of the single crystal thin films was investigated by double crystal X-ray diffraction (DCXD). The temperature dependence of the energy band gap of the $MgGa_2Se_4$ obtained from the absorption spectra was well described by the Varshni's relation, $E_g(T)=2.34 eV-(8.81{\times}10^{-4}eV/K)T^2/(T+251K)$. The crystal field and the spin-orbit splitting energies for the valence band of the $MgGa_2Se_4$ have been estimated to be 190.6 meV and 118.8 meV, respectively, by means of the photocurrent spectra and the Hopfield quasicubic model. These results indicate that the splitting of the ${\Delta}so$ definitely exists in the ${\Gamma}_5$ states of the valence band of the $MgGa_2Se_4$/GaAs epilayer. The three photocurrent peaks observed at 10 K are ascribed to the $A_{1^-}$, $B_{1^-}$exciton for n = 1 and $C_{27}-exciton$ peaks for n = 27.

A stoichiometric mixture of evaporating materials for $ZnIn_2Se_4$ single crystal thin films was prepared from horizontal electric furnace. To obtain the single crystal thin films, $ZnIn_2Se_4$ mixed crystal was deposited on thoroughly etched semi-insulating GaAs(100) substrate by the Hot Wall Epitaxy (HWE) system. The source and substrate temperatures were $630^{\circ}C$ and $400^{\circ}C$, respectively. The crystalline structure of the single crystal thin films was investigated by the photoluminescence and double crystal X-ray diffraction (DCXD). The carrier density and mobility of $ZnIn_2Se_4$ single crystal thin films measured from Hall effect by van der Pauw method are $9.41\times10^{16}cm^{-3}$ and $292cm^2/v{\cdot}s$ at 293 K, respectively. The temperature dependence of the energy band gap of the $ZnIn_2Se_4$ obtained from the absorption spectra was well described by the Varshni's relation, $E_g(T)=1.8622eV-(5.23\times10^{-4}eV/K)T^2/(T+775.5K)$. The crystal field and the spin-orbit splitting energies for the valence band of the $ZnIn_2Se_4$ have been estimated to be 182.7 meV and 42.6 meV, respectively, by means of the photocurrent spectra and the Hopfield quasicubic model. These results indicate that the splitting of the ${\Delta}so$ definitely exists in the ${\Gamma}_5$ states of the valence band of the $ZnIn_2Se_4/GaAs$ epilayer. The three photo current peaks observed at 10 K are ascribed to the $A_{1}-$, $B_{1}-exciton$ for n = 1 and $C_{27}-exciton$ peaks for n = 27.
