This study is investigated the effect of sensitivity upon pattern of the four-digit personal identification numbers(PINs) of A-university students. Under survey 2, PINs were collected after each student had information about his PINs were used in disclose his test scores, But Under survey 1, each student didn't have. Survey 2 is viewed more sensitive situation than survey 1 to students. The rate of occurrences of most common PINs which were created by the reason of easiness to remember or to use without caution, in survey 2 is five times less than survey 1 and using rate of girl students are considerably less than that of boys. By comparing frequencies of digits used at each position, it is found that significant differences exist between two surveys in the first, second and forth position except third. PINs are represented by the polygonal graph with that X-axis shows position and Y-axis shows digits from 0 to 9 used at each position. There are many different figures between two surveys. This study shows that students are more anxious about using the PINs in survey 2 which is viewed more sensitive than survey 1.

Since the early 20th century photo based art and effort to creative experiment, to pursue the essence of creation to escape from stereotypes between form and media, expression and technology, has been continued persistently. Photomontage was born as an artistic attempt for the new representation. Basically photomontage is configured to visually emphasize the message as a work to produce new meaning by combining the various images that are intentionally selected. The photomontage as a visual art, dialectic of text and image that is to pursue a new format to be out the concept already existing, have been developed, the concept is similar to the modern multiple art. The value of photo montage is to explore of the photo, not limited to describe or reproduce as a deformation, the new possibilities for creative expression and the experience of the day-to-day operation for the implementation of the scheme.

The purpose of this thesis is to examine ontology of digital photo image based on a Simulacre concept of Gilles Deleuze & Jean Baudrillard. Traditionally, analog image follows the logic of reproduction with a similarity with original target. Therefore, visual reality of analog image is illuminated, interpreted, and described in a subjective viewpoint, but does not deviate from the interpreted reality. However, digital image does not exist physically but exists as information that is made of mathematical data, a digital algorithm. This digital image is that newness of every reproduction, that is, essence of subject 'once existing there' does not exist anymore, and does not instruct or reproduce an outside target. Therefore, digital image does not have the similarity and does not keep the index instruction ability anymore. It means that this digital image is converted into a virtual area, and this is not reproduction of already existing but display of not existing yet. This not-being of digital image changes understanding of reality, existence, and imagination. Now, dividing it into reality and imagination itself is meaningless, and this does not make digital image with technical improvement but is a new image that is basically completely different from existing image. Eventually, digital image of the day passes step to visualize an existent target, nonexistent things have been visualized, and reality operates virtually. It means that digital image does not reproduce our reality but reproduces other reality realistically. In other words, it is a virtual reproduction producing an image that is not related to a target, that is to say Simulacre. In the virtually simulated world, reality has an infinite possibility, and it is not a picture of the past and present and has a possibility as the infinite virtual that is not fixed, is infinitely mutable, and is not actualized yet.

Architectural evidence of Gaya is insignificant than any other area. In this situation, house-shaped earthenware is particularly helpful in the study of Gaya architecture. However, house-shaped earthenware is not a building, it has just the shape of buildings. So, we have to find out architectural evidence from that. In this paper, I tried to estimate the architectural characteristics of Gaya through house-shaped earthenware in detail. I also consulted historical records, archeological results, and other scholars' papers. The results are as follows. First, house-shaped earthenware can be classified into three types according to its shape, and each type has distinct architectural structural characteristics. Second, house-shaped earthenware generally has a gambrel roof, and the characteristic of architectural design with the gable side of the gambrel roof as a front is the biggest feature of Gaya architecture. Third, various types of buildings existed according to their functions in Gaya architecture, and house-shaped earthenware was showed buildings of ancient storage, pens, and residences, which are symbols of the richness among various types of buildings.

This paper is an attempt to discuss the history and the current state of 'SF theaters.' SF theater is still an unfamiliar genre to the public, and may surprise some, given that the stage is perceived as an insufficient space for stretching the scientific imagination. Since 2010 works that bring the scientific imagination into the theater have frequently been performed, and a recognition of SF theaters began to be established. Producers came to be absorbed in human psychology, and our isolation amidst the progress in technology, as well as in the absurdities of the world, while giving up the ideal of realistic descriptions. This became the foundation for SF theaters in South Korea today. Starting from the research history and the conceptual change in SF theaters, this study examined the status of SF dramas going back to the colonial period for SF theaters. Through inquiring into the history of SF theaters, we were able to derive the following implications and problems. Firstly, as they are based on future society or technical improvement without consideration of scientific probability or rationality, the scientific imagination is too absent for the work to be named 'SF theater.' Secondly, while being highly evaluated as an attempt to integrate science and stage in an era that emphasizes convergence, when we delve into the creativity of a material it is noticeable that the view of the world is still regressive. Thirdly, there are many cases in which scripts lean on SF classics or Japanese original works. Nevertheless, if young creators' diverse attempts in a genre can breathe with the contemporary audience desiring a new material, the foundation of a Korean-style SF theater may be expanded to include more significant work.

This study identifies the symbolism of cross symptoms of different classes during the modernization process based on the imagery of and , both of which are Korean films made in the same era of the 1960s. The study referred to a number of Korean family movie films in the 1960s, in particular and , which are notably different in ways of expression and in social class of the subject matter, and identifies how the films express the mixed aspects of the cross modernization period. The film uses a grotesque expressionist method to voyeuristically look into a newly emerging middle class family, and the deconstructive aspect of a family unit whose excessive desire leads to its own ruin; thus, the film presents a new perspective into the various social issues that emerge in the near future. In contrast, engages realistic depictions to describe in detail the deep conflict of pain and hope within the hardships of life from the urban poor through a deep family conflict. Ultimately, the two films expose the various social issues through the familiar and the unfamiliar that appear from the mixed aspects of the cross modernization period, in other words, the conflicting images of the traditional and the modern.

The purpose of this study was to pay attention to the increase in the frequency of expression of butterflies and insects, whose decrease in the number of individuals is symbolized as a measure of environmental pollution, among the various motifs of nature as we go through the COVID-19, when we realized the importance of nature. The scope of this study was limited to fashion collection fashion show photos and interview articles of online for fashion collections from 2019 to 2023. As a result of the study, 185 butterfly motivation fashion design appeared, and digital printing techniques were the most used as a type of plane expression method. Along with this, techniques such as quilting, embroidery, and beading have appeared a lot as techniques to express the planar motif of butterflies. As for the three-dimensional expression types, 3D printing, laser cutting, corsage techniques, and draping techniques showed similar proportion. It can be seen that the expressed butterfly motif had more realistic description the shape of the butterfly as it was than abstract expressions. In conclusion, it can be seen that the butterfly motif fashion design over the past five years contains a stronger message about the environment than the butterfly motif fashion in the past. It was confirmed that it is a motif with a great symbolic meaning that can convey an eco-friendly message beyond just the morphological beauty and colorful design elements of the butterfly.

Vampilov, who is not well known as a playwright in domestic, is acknowledged comparable to Anton Chekhov in Russia. This paper was planed in order to promote a unsatisfied study until now in domestic for works by Vampilov and studied a part of composing play to put on the stage for , a drama written by Vampilov. This paper, originated from a viewpoint that actor have to complete the final text of the play for audiences to read depending on the drama and based on work features and characters of Vampilov, established an analysis scheme according to segments of unit actions for actions of Sarafanov, the character of the play, in order to achieve a purpose under suggested situation at the drama and focused on completing purposes per units individually. We have analyzed Sarafanov and his actions referring patterns and probabilities of the characters in the other works by Vampiov and regarded it as the important item together with logical basis of actions. Lyric and humanism emphasizing works by Vampilov, affected by Anton Chekhov and Nikolai Vasilevich Gogol, are acknowledged as realistic descriptions using contingency and a play within a play outstandingly and emphasized an importance of human relation. We have selected as a primary way to compose action text that audiences would read on the stage and used it as the method to design action of the characters in order to activate natural good of Sarafanov and general absurdities that human, does creative works, never give up purposes of ideal life.

Since ChatGPT was released in 2022, the generative artificial intelligence (AI) industry has seen massive growth and is expected to bring significant innovations to cognitive tasks. AI-based image generation, in particular, is leading major changes in the digital world. This study investigates the technical foundations of Midjourney, Stable Diffusion, and Firefly-three notable AI image generation tools-and compares their effectiveness by examining the images they produce. The results show that these AI tools can generate realistic images of tomatoes, strawberries, paprikas, and cucumbers, typical crops grown in greenhouse. Especially, Firefly stood out for its ability to produce very realistic images of greenhouse-grown crops. However, all tools struggled to fully capture the environmental context of greenhouses where these crops grow. The process of refining prompts and using reference images has proven effective in accurately generating images of strawberry fruits and their cultivation systems. In the case of generating cucumber images, the AI tools produced images very close to real ones, with no significant differences found in their evaluation scores. This study demonstrates how AI-based image generation technology can be applied in agriculture, suggesting a bright future for its use in this field.

The aim of this study was to find an analytic solution to the problem of determining the optimal capacity (lot-size) of a batch-storage network to meet demand for a finished product in a system undergoing random failures of operating time and/or batch material. The superstructure of the plant considered here consists of a network of serially and/or parallel interlinked batch processes and storage units. The production processes transform a set of feedstock materials into another set of products with constant conversion factors. The final product demand flow is susceptible to short-term random variations in the cycle time and batch size as well as long-term variations in the average trend. Some of the production processes have random variations in product quantity. The spoiled materials are treated through regeneration or waste disposal processes. All other processes have random variations only in the cycle time. The objective function of the optimization is minimizing the total cost, which is composed of setup and inventory holding costs as well as the capital costs of constructing processes and storage units. A novel production and inventory analysis, the PSW (Periodic Square Wave) model, provides a judicious graphical method to find the upper and lower bounds of random flows. The advantage of this model is that it provides a set of simple analytic solutions while also maintaining a realistic description of the random material flows between processes and storage units; as a consequence of these analytic solutions, the computation burden is significantly reduced.
