Several herbs were tested for their antimicrobial activities during preservation of soy sauces. The herbs which resulted in retarded growth of film yeasts were extracted and added to various media such as koji-extract agar, buion-peptone agar to elucidate effects on the growth of film yeasts, Aspergillus oryzae and Bacillus subtilis. The results obtained were as follows: 1) Addition of phellodendron powder resulted in retarded formation of film in fermented soy sauces. Film was produced after 2 days without addition of the phellodendron powder. However, formation of film was observed after 8 days when 0.5 per cent of the phellodendron powder was added, and after 12 days when 1.0 per cent of the powder was added to fermented soy sauce. 2) For the amino acid soy sauce, formation of film was retarded for 6 days by 0.5 per cent of the pow der and for 8 days by 1.0 per cent of the powder. 3) Repression of film yeasts by addition of helenii and camphora powder was recognized respectively, but other herbs were appeared to have no detectable effects. 4) Growth of film yeast and Asp. oryzae way, retarded for 5 days on koji-extract agar plates which contain 0.5 per cent of phellodendron extract. Bac. subtilis also showed retarded growth for 5 days on buion-peptone agar plates containing the same amount of the extract. 5) Retarded growth of film yeast for 5 days was obtained when grown on koji-extract agar plates containing 15 per cent of sodium chloride and 0.3 per cent of phellodendron powder, however, no growth of Asp. oryzae was obtained on this concentration of sodium chloride. Growth of Bac. subtilis was repressed for 5 days on buion-peptone agar plates which contain 15 per cent of sodium chloride and 0.1 per cent of phellodendron powder.

Today, the 3D character animation is easily accessible from most of the film such as an actuality film, animation, games, or advertising. However, such a smooth movement of characters is a result obtained by Key Frame operation which skilled animators worked with data obtained through expensive equipment such Motion Capture for a long time. Therefore, to modify or to give other effects is not easy. In some cases, character's action made according to the personal feeling could be different with universal expectations of audiences, because it might be not appropriate to make regulations generalized between character's action by animater's design and emotional reaction of audience. In this research, it is aimed to show the way which is easily to blend and modify 2-3 Biped animation data by offering the operation tools of 3-D rotation using 3D Studio MAX Script. By this tool E.A.M., we can have various researches for quantities relation of between walking and emotional reaction.

This research tries to interpret Montage der Assoziation shown in animations. Eisenstein's 'Montage' is "Montage der Assoziation" where a variety of Montage pieces are combined, symbolizing one aggregate image. Though influenced by Russian Formalist Film Theory and Kuleshov, Pudivkin and Rudolf Amheim, by contraries, he recognized Montage as an issue between an artist and the audience and an anti-representation apparatus. Especially, he developed the mind action issue previously advocated by Eikhenbaum and deemed the audience's role an essential part in completing a film. Montage expression implied in Eisenstein's theory can be regarded as attraction, collision, and dynamic and intellectual Montage. However, with an in-depth approach, Montage der Assoziation can be interpreted by repetitive, relative and juxtaposed analysis. The reason is that animation Montage is a visual action which takes place in a row among scenes and in the frame. This research addresses communications with the audience which are attained by Montage der Assoziation. In other words, this research makes an in-depth access to how Montage der Assoziation appears and communicates with the audience in an animation work.

It is currently well known that surface textures act as lubricant reservoirs, entrap wear debris, and hydrodynamic bearings, which can lead to certain increases in load-carrying capacities. Until recently, the vast majority of research has focused on parallel sliding machine components such as thrust bearings, mechanical face seals, piston rings, etc. However, most sliding bearings have a convergent film shape in the sliding direction and their hydrodynamic pressure is mainly generated by the wedge action. Following the first part of the present study that investigates the effect of groove position on the lubrication performances of inclined slider bearings, this paper focuses on the effects of groove depths and film thicknesses. Using a commercial computational fluid dynamics (CFD) code, FLUENT, the continuity and Navier-Stokes equations are numerically analyzed. The results show that the film thickness and groove depth have a significant influence on the pressure distribution. The maximum pressure occurs at the groove depth where the vortex is found and, as the depth increases, the pressure decreases. There is also a groove depth to maximize the supporting load with the film thickness. The friction force acting on the slider decreases with deeper grooves. Therefore, properly designed groove depths, depending on the operating conditions, can improve the load-carrying capacity of inclined slider bearings as compared to the bearings without a groove.

The materials used in the title sequence connotes a style & a content of film comprehensively. Therefore, the effect of emotional expression can be changed according to what materials are selected. Thus, the materials of which 42 title sequences are collected for the last 10 years are classified, and the category of materiality & material degree are defined with the semiotic rectangle. To investigate intensity of the material degree, the survey was done. As a result of the survey, the intensity was classified into 3 levels of material degree. The category of materiality used according to the genre of film was analyzed. As a result of the analysis, the materiality was selected according to the content regardless of genre, but there's any difference in the material degree. The intense material degree was used in a thriller and an SF mystery genre, and the medium one was used in the general genre, but, above all, drama and action genre. The weak one was used in a variety of genre, but specifically horror, SF mystery genre. It is significant that this study suggested the expression method in accordance with selection of materials in producing a title sequence to visualize film symbolically.

is a movie about the frustration and the despair of young people in Korean society today. It is different from the previous Lee Chang-dong's film in that it provides the main character's perception and feelings about the world as the ultimate cause of the protagonist's actions. Lee Chang-dong's characters begin to change from . The main character of Burning goes one step further. He seems to believe that the main character's only weapon to overcome the logic and constraints of reality is obsessive and compulsive behaviors. Unlike previous movies, the character in Burning is a person who practices awareness and proves his character through action. I will analyze characters in to suggest the change of film form. Especially I will look at how the character's actions and the writer's own voice can meet and what results it bring about in this movie. It will lead to his changes in film form and an idea on the young people in Korean society today.

This article analyzed the new changes Hong Kong director Lin Chaoxian has brought to theme films of Mainland China and the factors affecting these changes. The objects of the analysis are Lin Chaoxian's films (2016), (2018), and (2020). Compared with Mainland China directors suffering from heavy political burden, Dante Lam directed theme films based on the model from commercial films and adopted lots of elements from Hong Kong films. There, the ideology expression in these theme films was no longer rigid, but a diversified value embodiment resonating with the audience. At the same time, these theme films achieved higher commercial value, in which the stereotyped and unrealistic hero images were replaced by realistic and compound characters, and the display of cool or violent action scenes contributed to lots of visual feasts. All the changes were influenced by the audience preferences and the development of private enterprises in Mainland China.

This dissertation is considerably studied Faction Genre which is embossed as a new image content, and it is figured out practical used works' possibilities for Korea film production's varieties. Faction, a neologism, which is combined by Fiction and Fact, is a boundary as limits. If authentic history is closed to a truth, it is a record history description method. Also, if unauthorized history is closed to a fake, it is a fictitious history description method. In addition, macro history and micro history are respectively connected to social criticism's matter and personal action, and these can make various analyses, depend on a boundary's limits and personal analysis. On the other hand, history film could be remembered to audience merely history film itself without existed history's fact. However, there are Faction Genre's Genre possibility and film's attraction which indirectness experience of historic fact could be experienced through film. For Faction Genre’s developing solution, there are three cognitive switches; audience's interpretation ability about history film through watching perception, linking between the past and the present for audience through communication with history, audience's considerable decision about history first or fiction first as film writer's interpretation. Above all, hopefully filmic pressure can be shown with historical true to audience. Therefore, it would be Korea Faction Genre's attraction and hope.

This study examines the ways District 9, a film released in 2009, reworks the sci-fi genre to explore the human encounter with "other" alien populations. Like Avatar, released in the same year, District 9 addresses the tropes of conflict over land and human-alien hybridity and introduces non-humans and aliens, not as invaders, but as objects of human oppression and cruelty. Unlike many other science fiction films where the encounter between humans and non-humans occurs in an unidentifiable future time and location, District 9 crosses genre barriers to engage with urban realism, producing a social critique of contemporary urban population problems. The arrival of aliens in District 9 occurs as part of the recorded human past and the film's action is carried out in the present time in the specifically identified city of Johannesburg. A distinctly anti-Hollywood film that locates the action at the street level, District 9 plays out human anxieties about contact with others by referencing the divisions and conflicts historically attached to South Africa's sprawling metropolis and its current problems of urban poverty and illegal immigrants. Focusing on how this particular urban setting frames the film, the study investigates the ways Blomkamp's sci-fi film about extra-terrestrials presents a curious postcolonial mix of aliens and immigrants surviving in abject conditions in an urban slum and forces a realistic examination of the contemporary social problems faced by South Africa's largest city and by extension other major global cities. The paper also examines the film's representation of the human-alien hybrid and its potential as a force to resist human exploitation of the other. It also claims that though the setting is highly local, District 9 speaks to a wider global audience by making obvious the exploitative practices of profit-seeking multinationals. A sci-fi film that is keen on making a social commentary on urban population conflicts, District 9 resonates with the wider sense of insecurity and fear of others that form the horizon of the uncertain and potentially violent contemporary human world.

A mathematical model was proposed to analyze the damped motion of contact lens which is initially displaced from the equilibrium position. The model incorporates the differential equations and their numerical solution program, based on the formulations of restoring force arising from the capillary action in the tear-film layer between the lens and cornea. The model predicts the capillary action induced surface tension, time dependence of displacement of lens when it is released from the equilibrium position. It seems that the motion of lens is similar to the typical over-damped oscillation caused by the large viscous friction in the liquid layer between the cornea and lens. The effect of variables such as base curves, lens diameters and thickness of tear film layer were illustrated by the computer simulation of the derived program. The time required for the lens to return to the original position increases as the liquid layer thickness increases and it decreases as the diameter of lens increases. With the certain value of base curve the time interval is found to be minimum. The free vibrations of lenses were also simulated varying the parameters such as base curve, diameter, layer thickness. The resonant frequencies are inversely proportional to the liquid layer thickness and it increases as the lens diameter increases. The resonant frequency of lens has a maximum when the diameter is of certain value. If the external impulse or force of the same frequency as the natural frequency of contact lens acted on the cornea in vivo it may cause an excessive movement and thus it might cause the distortion 10 the lens or be pulled off the eye.
