The purpose of this study is to develop Blue-Jean Design for Ideal Body Shape. The final aim of Fashion design is looks beauty of people by optical illusion. This study is based on Gestalt therapy and, is blue jeans design using optical illusion of vertical line for ideal beauty body image. Optical illusion for blue-jean design effect to achieve the ideal body shape. We can accumulate the preceding study for modern clothing from design and the related optical illusion effects. Vertical line stitches have all the advantages especially in pants design. I design blue jeans using optical illusion theory. The results of this study are as follows: First, Vertical line helps that jean has the long body shape effectively. Second, Jeans which have two or more vertical lines is more effective than simple Jean in order to make slim body shape. Third, Appropriate position of horizontal lines can be effective to make long body shape. Fourth, Top stitch, pin-tuck and pleats can be applied to vertical or horizontal lines instead of cutting lines.

Slashes, deprived from the Crusaders' military uniforms, take their places among the fashion terms in modern fashion, and they are represented with some techniques such as fraying fabrics or making holes. Slashes are also used in various ways across all the fashion areas including clothing to accessaries. Slashes, which were once used to represent a solid body and to make a body move suitably, are used not only to express the formative of clothing but also to allow wearing sensations and functionality to wearers depending on their daily lives and the movements of their activities in modern fashion design. Optical illusions of fashion, image variabilities, functionality and ornamentation, and design principles, which were once represented with materials, colors, and details mainly used in fashion designs, are represented using slashes in modern fashion.

This paper describes the general considerations and operational applications of aircraft night vision goggle(NVG). The operators should recognize the NVG characteristics, natural night light sources and interoperability between them. And they have to keep attention to the method to take steps to avoid misperceptions, illusions during flight, and the negative impact on the effectiveness and safety of the mission. The considerations based on the interoperability between NVG and night operation suggest the evaluation items of NVG field test and flight test.

Helicopter accidents due to spatial disorientation in low visibility conditions continue to persist as a major issue. These incidents often stem from human error, typically induced by stress, and frequently result in fatal outcomes. This study employs machine learning to analyze flight data and evaluate the efficacy of a flight illusion detection algorithm, laying groundwork for further research. This study collected flight data from approximately 20 pilots using a simulated flight training device to construct a range of flight scenarios. These scenarios included three stages of flight: ascending, level, and descent, and were further categorized into good visibility conditions and 0-mile visibility conditions. The aim was to investigate the occurrence of flight illusions under these conditions. From the extracted data, we obtained a total of 54,000 time-series data points, sampled five times per second. These were then analyzed using a machine learning approach.

This paper is to investigate how cognitive bias of college students and entrepreneurs relates to perceived risks and entrepreneurial opportunities that represent uncertainty, and how various cognitive bias and entrepreneurial efficacy In the same way. The purpose of this study is to find improvement points of entrepreneurship education for college students and to suggest problems and improvement possibilities in the decision making process of current entrepreneurs. This empirical study is a necessary to improve the decision-making of individuals who want to start a business at the time when various attempts are made to activate the start-up business and increase the sustainability of the existing SME management. And understanding of the difference in opportunity evaluation, and suggests that it is necessary to provide good opportunities together with the upbringing of entrepreneurs. In order to achieve the purpose of the study, questionnaires were conducted for college students and entrepreneurs. A total of 363 questionnaire data were obtained and demonstrated through structural equation modeling. This study confirms that there is some relationship between perceived risk and cognitive bias. Overconfidence and control illusions among cognitive bias have a significant relationship between perceived risk and wealth. Especially, it is confirmed that control illusion of college students has a significant relationship with perceived risk. Second, cognitive bias demonstrated some significant relationship with opportunity evaluation. Although we did not find evidence that excess self-confidence is related to opportunity evaluation, we have verified that control illusions and current status bias are related to opportunity evaluation. Control illusions were significant in both college students and entrepreneurs. Third, perceived risk has a negative relationship with opportunity evaluation. All students, regardless of whether they are college students or entrepreneurs, judge opportunities positively if they perceive low risk. Fourth, it can be seen from the college students 'group that entrepreneurial efficacy has a moderating effect between perceived risk and opportunity evaluation, but no significant results were found in the entrepreneurs' group. Fifth, the college students and entrepreneurs have different cognitive bias, and they have proved that there is a different relationship between entrepreneurial opportunity evaluation and perceived risk. On the whole, there are various cognitive biases that are caused by time pressure or stress on college students and entrepreneurs who have to make judgments in uncertain opportunities, and in this respect, they can improve their judgment in the future. At the same time, university students can have a positive view of new opportunities based on high entrepreneurial efficacy, but if they fully understand the intrinsic risks of entrepreneurship through entrepreneurial education and fully understand the cognitive bias present in direct entrepreneurial experience, You will get a better opportunity assessment. This study has limitations in that it is based on the fact that university students and entrepreneurs are integrated, and that the survey respondents are selected by the limited random sampling method. It is necessary to conduct more systematic research based on more faithful data in the absence of the accumulation of entrepreneurial research data. Second, the translation tools used in the previous studies were translated and the meaning of the measurement tools might not be conveyed due to language differences. Therefore, it is necessary to construct a more precise scale for the accuracy of the study. Finally, complementary research should be done to identify what competitive opportunities are and what opportunities are appropriate for entrepreneurs.

The present study examined the variations in personality variables according to different types for the Korean view of the afterlife, including 'extinction type', 'the other world-oriented transmigration type', 'heaven/hell type' and 'obscurity type'. The results may be summarized as follows: (1) 'the other world-oriented transmigration type' and 'heaven/hell type' showed significantly stronger belief in a just world than 'extinction type', (2) 'extinction type' and 'obscurity type' showed more external attribution for accidents than 'heaven/hell type', (3) there was no difference in unrealistic optimism levels, (4) depending upon the types for the view of the afterlife, not only preferred self-enhancing biases but also positive illusions which related to life satisfaction were different, (5) 'extinction type' showed stronger risk-taking tendency than 'heaven/hell type'. These results were explained in terms of features that belong to each afterlife view. Finally, we discussed the limitation of this study and the directions for future study.

The purpose of this study is to analyze the characteristics of current fashion illustrations within the framework of Multi-space method. Multi-space means being piled up one moment & space on others, and being amassed in a scene. This method is related with Dadaism, Surrealism and Postmodernism, and also influences on the current fashion illustration. In this study, the types of Multi-space method could be classified into 4 types; Repetitive Time Mixture in Multi-space, Juxtaposed Time Mixture in Multi-space, Reiterated Space Mixture in Multi-space, Projected Space Mixture in Multi-space. The characteristics of Multi-space were analyzed and the results are as followed. The distinctive methods for Time Mixture in Multi-space are repetition and juxtaposition in a scene. Time Mixture in Multi-space can make the nonlinear narration and unreal illusory space in fashion illustrations more effectively. Reiterated Space Mixture in Multi-space can be related with the heterogeneous, surrealistic illusions in current fashion illustrations. Projected Space Mixture in Multi-space can be characterized into inter-penetration. It can derive spectators to mix the projected & transparent images in a scene for their own imaginary stories. The final imagination can be made differently according to the personal experiences of spectators.

The purpose of this study was to survey Navajo's textiles of the transitional period(1868-1890) and to examine appearance background of those textiles. The two study questions were central to the project. 1) What were characteristics of eye-dazzler and pictorial in the transitional period? 2) How developed was the American trader's role? To perform the purpose, literatures on this subject were surveyed, investigation of textiles in Arizona State Museum and Historical Museum of Arizona were accomplished. The results of this study were as follows: 1. Eye-dazzler is called because of their small, serrate triangle and diamond patterns in intense, contrasting colors. Eye-dazzler mostly used Germantown yam and wedge-weave technique. Germantown was a plied yam colored with synthetic dyes. Wedge-weave technique used optical illusions and an undulating technique to create an effect of motion and rhythmic symmetry. 2. The Americans began to intern Navajos at Bosque Redondo, New Mexico in 1863. During their stay at Bosque Redondo, the Navajo came into greater contact with Rio Grande blankets. The influence of designs of these becomes increasingly important in the eye-dazzler. 3. Pictorial materials included rich new sources the railroad provided and living environment of animals, plants, hogans, neighbors, deities that interested the Navajo. Also, sandpainting textiles were a pictorial. Three types of textiles utilized: yei, yeibichai, and sandpainting tapestry. 4. The arrival of the railroad caused many changes for the lives and textiles of the Navajos. The railroad brought a new client into the Navajo, and the Navajos attempted new textiles with design-inspiring fresh materials to adjust taste of the eastern purchasers.

When a human-being gets a wrong perception about any object is a misunderstanding and what they feel through sense of sight is an optical illusion. The study about those illusions have been given out to not only the fields of fine art, design, and animation but also psychology First, this paper puts in order an op art, influenced in fine art and design, and animation using persistence of vision, relating an optical illusion. Second, it analyses the theory of art form using an optical illusion about brightness, saturation, contrast and luminosity of color. Finally, it makes an experiment of standard of perception on students. The study of art form using an optical illusion is another way to represent fine art comparisons and visual image including animation.
