The magic square is one of the number arrangements and the sums of each row, column, and diagonal are all equal. The meaning of "方" is "Square". If we don't consider the condition of 'square' then is it possible any number arrangement? There are many special number arrangements such as "magic five number circle(緊五圖)", "magic six number circle(聚六圖)", "magic eight number circle(聚八圖)", "magic nine number circle(攢九圖)", "magic eight camp circle(八陣圖)", "magic nine camp circle(連環圖)" in the ancient Chinese mathematics books such as "楊輝算法", "算法統宗". Also, there is a very special and beautiful number arrangement Jisuguimoondo(地數龜文圖) in the mathematics book "Goosuryak(九數略)" written by Choi suk jung(崔錫鼎) in the Joseon Dynasty. In this study, we introduce a various number arrangements and their properties.

The purposes of this study were to compare core muscle activities with and without the use of Pilates resistive equipment during bridging exercises and to investigate the efficacy of a Pilates device. Fourteen healthy individuals (6 males, 8 females) between 20 to 26 years of age were examined. They were engaged in a bridging exercise with and without a magic circle. Three consecutive repetitions of each exercise were performed. Surface electromyography (sEMG) was used to measure the electrical activities of the right side internal oblique, the adductor longus, the multifidus, and the gluteus maximus muscles. Normalized EMG activities were compared using a paired t-test and the level of significance was set at =.05. The results showed that the EMG activities of the internal oblique (p=.0078), the adductor longus (p=.0007), and the gluteus maximus (p=.0001) muscles were significantly higher when using the magic circle during the Pilates bridging exercise. Also, statistically significant change existed in the multifidus muscle (p=.0106). The bridging exercise, combined with hip adduction using the magic circle, may enhance core stabilization. Therefore, using a magic circle during hip adduction combined with bridging exercise may be recommended usefully for individuals wanting to strength the core muscles. Further research is needed to access the nature of motor control of the Pilates mat exercises and to deliver exercise intervention for lower back pain patients.

The purpose of this study is to identify online-game players' desire in cheating programs through Rene Girard's theory of mimetic desire. Cheating programs disrupts the magic circle of the game with denying the lusory attitude that players should have. The cheating players' desires do not go directly to victory, but are mediated by a virtual 'model player' which the rules of the game imply. They are internally mediated, so there is constant conflict in the play. Cheating players' desire to enhance skills by technology is defined as a false desire for transhuman.

The objective of this thesis is to unfold Latin American trends overlapping with Korean contemporary novels as an interesting scene in the circle of Korea literature at the beginning of the 21st century. This study was conducted largely in two directions. One is examining how long novel A Guest of Seok-yeong HWANG, a representative realist writer in Korea, and another long novel One Hundred Years Motel (Baeknyeon Motel) of Cheol-woo IM, a writer who has expressed Korean shamanic flowering as his fictitious characteristic since the 1980s, meet and interact with the world of magic realism in long novel One Hundred Years of Solitude of G. G. Marquez born in Colombia, Latin America, and the other is discussing the fictional techniques of H. L. Borges overlapping with short stories in novel collections The Age of Twenty and Fictions of Midnight by, respectively, young writers Yeon-soo KIM and PARK Hyeong-seo who displayed a unique world of fictions in the 2000s. For these purposes, we developed the points of discussion from the viewpoint of 'the meeting of two essences' for Seok-yeong HWANG and Marquez, of 'the meeting of two 'hundred years'' for Cheol-woo IM and Marquez, of 'novel writing as the finding of the original' for Yeon-soo KIM and Borges, and of 'novel writing surrounding fictions' for Hyeong-seo PARK and Borges. Around 2000, the trend of Latin American novels emerged as a phenomenon in Korean novels. It was probably a natural consequence of contemporary writers' struggling with genres and post-genres, the overturn of the center and the periphery, and blurred boundaries. Seok-yeong HWANG, Cheol-woo IM, Yeon-soo KIM, and PARK Hyeong-seo borrowed the contents and techniques of Latin American novels, but further research is required on how continuously their works internalized the characteristic properties of Marquez-style, Borges-style or polyphonic Latin American novels and, by doing so, how much they expanded or determined their own line. This is why this study has been performed productively out of vital importance. In every age throughout history, there have been the phenomena of encountering and sympathizing, and overlapping and spreading with foreign novels. This study is meaningful in that it illuminated the aspects of Korean contemporary novels in the flow of world literature through tracing the origin and reality of the trend of Latin American novels emerging conspicuously through overlapping particularly with Korean novels published in the 2000s.

This Research is focused on ancient battle formation basing on the layout drawing of Yijinchongbang (manuals of learning military formations) in a strategy book in the late Joseon dynasty. The research topic is the principles of organic composition of battle formation and battlefield operating system by reforming the basic model of ancient battle formation. The research method is comparative analysis by reforming the battlefield operating system of types of disposition such as Obangjindisposition(Bangnjin; battle formation, Jikjin; direct battle formation, Gokjin; bend battle formation, Wonjin; round battle formation, and Yejin; keen battle formation), and Hyunmoojindo; turtle battle formation, Paljindo; all-rounder battle formation, Yookhwajindo; six flowers battle formation, Gugunjindo; nine forms battle formation. From the study results, Standoff Bombing of the battle formation in the late Joseon Dynasty basically started out from magic battle formation, but was then transformed into square, rectangle, pentagon, and circle. Also, the battle array composition used a 5-linear structure and was composed of 5 systems of circulation such as rectangle, square, diagonal, curve, and circle. The research findings elucidate the battlefield of the Joseon dynasty by establishing the real battle formation, and thus have military and academic value in suggesting possible tactics that can be used by modern training of military.

This study aims to analyze remediation of games and fictions in Korean virtual reality game fictions and to derive the storytelling of virtual reality game fictions through them. The purpose of this study is to explore the possibilities that Korean game fiction based on the web can be expanded as popular literature. The main character of the fiction is a male in his twenties. In the neoliberal society, he is set as a member of the neglected class and lacking privilege. He enters the virtual world because of the deficiency experienced in the real world. It minimizes the mediation process between the real world and the interface. On the other hand, the repetitive actions performed by the protagonist belong to the category of self - destructive labor. As a result, he shows signs of narcissism. In the Korean virtual reality game fiction, the magic circle appears blurred, and the real world and the virtual world are linked. In this process, the virtual world functions as a substitute space to solve the problem of reality. The establishment of such a space, and the resolution of conflicts are merely narrative characteristics of Korean game fictions that are different from North America and Europe.
