In producing anamorphic 3D advertisement projects, it is necessary to apply the principles of illusion art to distort the images output to the screen (Image Distortion) so that their display aligns with our visual perception in a real three-dimensional environment. We focuse on the methods of image distortion in the creation of content for anamorphic 3D advertisement screens in this thesis. We propose using Unity 3D's real-time rendering instead of the offline rendering method of compositing method, and employing UV grid mapping to replace the manual correction in Adobe After Effects(AE). The significance of this paper lies in simplifying the image distortion processing workflow in anamorphic 3D projects and optimizing the image distortion creation methods used in compositing method. In outdoor anamorphic 3D advertisement projects, the proposed image distortion creation method demonstrates significant advantages in terms of production time, process simplification, flexibility, and expansion possibilities. Our research provides new perspectives and methods for the creation of anamorphic 3D content, offering theoretical and methodological references for professionals working on similar contents.

Size, velocity, and time equivalence are mechanisms that allow us to perceive objects in three-dimensional space consistently, despite errors on the two-dimensional retinal image. These mechanisms work on common cues, suggesting that the perception of motion distance, motion speed, and motion time may share common processing. This can lead to the hypothesis that, despite the spatial nature of visual stimuli distorting temporal perception, the perception of motion speed and the perception of motion duration will tend to oppose each other, as observed for objects moving in the environment. To test this hypothesis, the present study measured perceived speed using Müller-Lyer illusion stimulus to determine the relationship between the time-perception consequences of motion stimuli observed in previous studies and the speed perception measured in the present study. Experiment 1 manipulated the perceived motion trajectory while controlling for the retinal motion trajectory, and Experiment 2 manipulated the retinal motion trajectory while controlling for the perceived motion trajectory. The result is that the speed of the inward stimulus, which is perceived to be shorter, is estimated to be higher than that of the outward stimulus, which is perceived to be longer than the actual distance traveled. Taken together with previous time perception findings, namely that time perception is expanded for outward stimuli and contracted for inward stimuli, this suggests that when the perceived trajectory of a stimulus manipulated by the Müller-Lyer illusion is controlled for, perceived speed decreases with increasing duration and increases with decreasing duration when the perceived distance of the stimulus is constant. This relationship suggests that the relationship between time and speed perceived by spatial cues corresponds to the properties of objects moving in the environment, i.e, an increase in time decreases speed and a decrease in time increases speed when distance remains the same.

Entrepreneurial self-efficacy is an important variable that explains people's attitudes and behaviors toward start-ups. In this study, we focused on individual psychological characteristics variables such as luck in belief and positive cognitive bias that affect entrepreneurial self-efficacy. Among these variables, we paid particular attention to luck in belief. The belief that business success depends on luck is widespread, but scientific verification about it has not been much. The reason for the academic indifference is that luck is a kind of superstition, related to precognition or extrasensory perception, and randomly caused by the external environment. The study of luck began in earnest as a measure to measure luck as an individual characteristic variable such as personality was developed. The purpose of this study is to examine the existing studies on luck in belief and to examine the effect of this luck in belief on positive cognitive bias and entrepreneurial self-efficacy through empirical analysis. For empirical analysis, this study conducted an on-line survey of 400 ordinary people and conducted a structural equation model analysis using AMOS 21.0 to verify the hypothesis. As a result of hypothesis testing, all hypotheses that luck in belief would have a positive effect on positive cognitive bias(self-enhancement bias, illusion of control bias, unrealism optimistic bias) were adopted. The hypothesis that positive cognitive bias(self-enhancement bias, illusion of control bias, unrealistic optimism bias) will have a positive effect on entrepreneurial self-efficacy was also adopted. Additional analysis was conducted to examine the mediating role of positive cognitive bias in the relationship between luck in belief and entrepreneurial self-efficacy, which showed that 'luck in belief→positive cognitive bias →entrepreneurial self-efficacy' were statistically significant. Through this, we confirmed the mediating effect of positive cognitive bias in the relationship between luck in belief and entrepreneurial self-efficacy. In the conclusion, the implications and limitations of the study were presented based on the results of this study.

Men's Po of (he Chosun period became simple and stable in shape as the nation moved from its early to late period. Re lines of the external structure of the clothing shows the beauty of the garment. Re lines generally derive their beauty from curved lines, gradually replacing the straight lines of the earlier part of the Chosun period. The linear beauty of the external structure of men's Po is found in the outline and silhouette. Generally in the early Chosun period it could be seen that H-shaped silhouettes, narrowed strips and flexible drapes descending to the ankles were still in use from the period of the Koryo dynasty And in the 17th century, or the mid Chosun period, considerable numbers of H-shaped drapes with wide sleeves and side Moo were seen. At the beginning of the 18th century, voluminous A-shaped outlines appeared. From the late Chosun period through the mid and late Chosun period, or the 18th and 19th centuries, the from silhouette changed from voluminous A-shapes to narrower H-shapes. The beauty of the lines of the external structure of men's Po is due to its harmonising with the straight body lines of men. The straight Git of the early Chosun period harmonises beautifully with the straight Baerae and Doryun and the curved Git of the later Chosun period similarly harmonises with the curved Baerae and Doryun lines. The shape of men's Po has a balance betweon right and left, centering around the Sup lines. The sleeves have the balanced beauty of vertical lines. Git and Sup have beauty through the balance of oblique and straight lines while Baerae and Doryun have similar balances through curves. Jikrung, Chulik, Dapho's side Moo, coat strings, Doryun and sleeves drape, all of which are manufactured by means of plane cutting, Pow together beautifully. Re Git, Sup, and the silhouette and drape of men's Po, which are also manufactured through plane cutting, make the wearer look tall and at the same time express the beauty of mature manhood. The linear beauty shown in men's Po during the Chosun Period have beauty through harmonizing with straight and curved lines, beauty balance, beauty of flow, beutity of emphasis and beauty of optical illusion.

This study was designed to investigate how the size perception of letters is influenced by its relation to the ground, visual angle, physical size, letter space and cognitive direction. As a stimulus, a word in the Numeral and Hangul respectively were used in Experiments I and II. Fifty four different configurations consisting of two grounds, three visual angles and nine physical sizes were used as test patterns in Experiment I, and one hundred and eight different configurations consisting of two ground, three directions, two letter spaces and nine physical sizes were used in Experiment II. Subjects were asked to make magnitude estimates for perceived size of test patterns in both Experiments I and II. The results imply that the ground and visual angle affected the perceived size of the Numeral as a focal figure. We found that in Experiment I, the perceived size of the focal letter was clearly underestimated when the rate of physical size was larger than the real size which was a hundred(as the size of standard stimulus), and it was overestimated when the rate of physical size was smaller than a hundred. It was found that the effect of Delboeuf illusion influenced the perceived size of letter. The result of Experiment II shows that the ground, physical size, letter space and the cognitive direction affected the perceived size of Hangul as a focal figure. These findings suggest that size illusion of letters is caused by the size relationship (contrast or assimilation) between a letter perceived as figure and its ground.

The film (2000) and (2016) are based on different time slips from each other. However, these two films have many common elements that make one illusion-based illusion. In the common elements, the main characters (being and thing) are traversed at different times and directed as a cyclical one. Also, among these, the movement link of the time and space has a commonality that it becomes possible through a medium ( - radio, you, there - pill). As a result, a series of scenes expressed in showed that the scene of produced in 2000 was greatly circulated. The reason why two movies have similar structure is that the basic framework of video media based on time slip is similar. Therefore, the purpose of this study is not to analyze the problem of quoting and borrowing of two films as mentioned in the paper. To add up, the material of video media is manifold which is a dynamic object of potential which is unlimited and opened, and by rearranging one media it can be created by escaping from one territory. Also, it is a study of analysis to contribute to producer or researcher as a time slip video creation reference connecting times based on the manifold arrangement from two films.

Nowdays many people using and learning 3D Software. However, like artists drawing by brush, that most of designers misunderstood that 3D Software is cover everything as a tool. This sort of situation, change of 3D Software will come to the front very seriously. It can be result about lack of understanding 3D in general and some kind of illusion about 3D Software. These were changing like training school that was teaching only function for technique. Therefore, to prevent above things, this research paper will be based on a conception, that compare with 3D which called cyber space and the real world. That is explanation of construction about 3D Software generally, that will basis how does people think about the world. It function of 3D Software will take concrete shape gradually, which is after general description and understanding and the users will be quick to understand, no need to difficult of access for beginners. In addition, higher education ay university is no longer training center. Lastly, it will be able to capability as an essentially figure. Nowdays many people using and learning 3D Software.

The weight of an object is an important research topic in terms of sense, and objects have size-weight, color-weight, and material-weight illusions due to the influence of size, color, and material and the weight of the object. Although temperature is a very important environmental factor in our daily life, there is a dearth of studies on how the temperature of an object affects its perceived weight. This study analyzed the effect of an object's temperature on the perceived weight. A stainless steel cup, in which weight and temperature are easily adjustable, was selected as a perceived weight measurement object; 5 temperature levels (0, 9, 20, 40, 70 degrees) and 2 weight levels (250, 400 g) were set. A total of 40 healthy men and women in their 20s participated in the experiment. The weight of the given cup compared to the reference cup was evaluated according to the modulus method. The study revealed that both temperature and weight significantly affected the perceived weight. The effect of temperature on the weight was different depending on the weight of the object. When the cup's weight was small (250 g), the temperature of the cup did not affect the weight. However, the perceived weight of a large cup (400 g) increased at a low temperature. This result suggests that the effect of temperature on the weight of an object depends on the size-weight illusion.

This study empirically analyzes whether bank capital channel and risk-taking channel for monetary policy work for domestic banks in South Korea by analyzing the impact of the expansionary monetary policy on the rate spread between deposit and loan, capital ratio, and loan amount. For the empirical analysis, the Uhlig (2005)'s sign-restricted SVAR(Structural Vector Auto-Regression) model is used. The empirical results are as follows: the bank's interest rate margin increases, the capital ratio improves, risk-weighted asset ratio increases, and the amount of loans increases in response to expansionary monetary shock. This empirical results confirm that bank capital channel and risk-taking channel work in domestic banks, similar to the previous research results. The implications of this study are as follows. Although the expansionary monetary policy has the effect of improving the bank's financial soundness and profitability in the short term as bank capital channel works, it could negatively affect the soundness of banks by encouraging banks to pursue risk in the long run as risk-taking channel works. It is necessary to note that the capital ratio according to the BIS minimum capital requirement of individual banks may cause an illusion in supervising the soundness of the bank. So, the bank's aggressive lending expansion may lead to an inherent weakness in the event of a crisis. Since the financial authority may have an illusion about the bank's financial soundness if the low interest rate persists, the authority needs to be actively interested in stress tests and concentration risk management in the pillar 2 of the BIS capital accord. In addition, since system risk may increase, it is necessary to conduct regular stress tests or preemptive monitoring of assets concentration risk.

The Byungsan Neo-Confucian Academy, a 17th-century World Heritage Site in Korea, is being praised as a manifestation of naturalness or non-artificiality of the traditional Korean borrowed scenery technique (借景, chagyeong). This study, however, aims to reinterpret the chagyeong of the Byungsan Academy (hereafter the Academy) as a device of illusion evoking an idealized vision of nature. In the process of interpretation, 'picture and frame'-a widely accepted expression that represents the chagyeong of the Academy-will be foregrounded as the pivotal concept mediating the change of perspectives from naturalistic to ideological. This study consists of the following three parts. First, it shows that 'picture and frame' represent a modern way of seeing the Academy as an architectural heritage in harmony with nature; it denotes pristine nature and the empty architectural frame that safely circumscribes the innate beauty of the natural landscape. Second, departing from the naturalistic perspective, this study argues that the architectural framework of the Academy composes scenography enticing the viewer to imagine the idealized, Confucian image of nature that compares to the landscape imagery found in the landscape poetry and paintings that were produced and appreciated by the 17th-century Confucian literati. Lastly, based on the above interpretation, this study stresses that the 'picture' one encountered at the Academy in the 17th century was not the framed scene of a natural landscape but the illusion it caused; the architectural 'frame' worked not as a symbol of naturalness but as an institutional apparatus of vision manipulating the way one sees-and therefore imagines-the landscape.
