Jusik ParkPurpose: The purpose of this study is to provide useful information on physical fitness training to improve the performance of Taekwondo demonstration majors by identifying the characteristics of physical fitness factors ac-cording to the performance level of university Taekwondo demonstration members. Method: The subjects of this study are Taekwondo demonstration members enrolled in K University located in D city. The differences in body structure, physical fitness factors, isokinetic muscle function of the knee joint, and anaerobic exercise capacity were compared and analyzed for 3 male students in the national demonstration group and 3 male students in the general demonstration group. Results: As a result of measurement of body structure, physical fitness factors, isokinetic muscle function, and anaerobic exercise capacity of the national demonstration team and general students, there was no statistically significant difference between groups. However, through the results of this study, it was confirmed that the ratio of flexor and extensor muscles needs to be improved to an ideal ratio of 55% to 65% as suggested in previous studies to prevent damage to the lower extremities of general students. In addition, the standing long jump and sargent jump, side step, eyes closed and one leg standing, and knee joint isokinetic muscle power showed a high-er tendency in the national demonstration group compared to the general students. There was no statistically significant difference between groups in the measurement results of anaerobic exercise capacity. Conclusion: Based on the results of this study, it is thought that it will be difficult to present the characteristics of the physical fitness factors according to the performance level of Taekwondo demonstration majors. However, considering the results of many previous studies and this study, it is thought that efforts to improve agility, power, and balance ability are needed to improve the performance of Taekwondo demonstration majors. It is judged that improvement of the flexion muscle/extension muscle ratio of the lower extremities is necessary to prevent addi-tional injuries.;Jihye Jeong;Jonggyu Son;Gangjun Kwon

Purpose: This study is a case study that analyzes the effects after planning and applying a functional training program to improve the performance of high school male freestyle wrestler. Methods: The subject of this study was one elite athlete in freestyle wrestling at K High School in D Metropolitan City. The contents of the applied functional training program consisted of 5 items related to flexibility, 5 items related to dynamic stabilization, 8 items related to muscular endurance, and 8 items related to muscle power improvement in consideration of the wrestling competition situation. After applying the functional training program twice a week at a frequency of 120 minutes per day for 5 weeks(10 times), changes in body composition, basic physical strength, maximal exercise load test, anaerobic exercise capacity, knee joint isokinetic strength and muscle power were analyzed. Results: Body composition, basic physical fitness, maximal exercise load test, anaerobic exercise capacity, isokinetic muscle strength and muscle power were measured before and after the application of functional training, and most of the measurement items showed positive changes after application of the program. In particular, a positive change in exercise duration and maximal oxygen intake as a result of the graded maximal exercise test indicates an improvement in cardiopulmonary endurance, and a decrease in peak drop among the anaerobic exercise capacity measurement items increases tolerance to fatigue. In addition, positive changes in knee joint isokinetic muscle strength and muscle power are very important physical factors for improving the wrestler s performance, and it is judged that the effect of the functional training program applied in this study is appropriately reflected. Conclusions: In summarizing the results of this study, the planning of the optimal functional training program taking into account the physical characteristics of the sport and individual athletes showed more developmental changes than the previous physical fitness training which depended on the intensity of training and the amount of training. This training method was considered to show the possibility of being fully utilized for the future improvement of elite athletes performance.
Toward the Aesthetics of Allegory
Jusik Park 한국비평이론학회 2009 비평과이론 Vol.14 No.1
In the history of the postwar literary criticism, no one has ever raised such a strong controversy as Paul de Man, the leading critic of the so-called Yale school. Although his name seems to have been considerably faded out from the contemporary literary scene, it still makes a haunting presence in the academy in many ways. The present study is motivated by the realization that the de Man reception of academy has taken a wrong tract by associating him with such phrases as deconstruction in America, the American counterpart of Derrida, or the modern-day inheritor of american formalism. This paper tries, in part, to serve as a corrective to such academic tendencies and instead to investigate de Man's intellectual trajectory from the standpoint of Benjamin specifically in terms of two antithetical categories of symbol and allegory. For this purpose, after reviewing the history of their reception briefly, this paper tries to practice a close reading of de Man's and Benjamin's major works which deal with this issue. Closely related to the issue is the term romanticism, romanticism not as a literary movement but as a touchstone of man's inevitable condition. For both of them romanticism becomes the very site of conflict between two modes of expression, the allegorical and the symbolic, and this motif repeatedly confers upon them a source material for their reflections upon diverse topics. More than any other essay, Benjamin's The Origin of German Tragic Drama serves as a decisive material for delving into the shadow of Benjamin in Paul de Man.

Proof of Work (PoW) based blockchains have limitations in throughput, time consumption, and energy efficiency. In these systems, a miner will consume significant time and resources to obtain a reward for contributing to the blockchain. To overcome these limitations, recent research on blockchains are focused on accelerating the speed, scalability, and enhancing the security level. By enhancing specific procedures of blockchain system, the level of data integrity supported by the blockchain can become more robust, and efficient. In this paper, a new blockchain consensus model based on the Bryllite Consensus Protocol (BCP) is proposed to support a hyper-connected massively multiplayer online game (MMOG) ecosystem. The BCP scheme enables users to participate directly in new consensus processes through a Proof of Participation (PoP) algorithm. In this model, the consensus algorithm has a simpler form while maintaining high security level. In addition, because the BCP scheme gives users an equal chance to make a contribution to the blockchain, rewards are distributed in an equal fashion, which motivates user participation. The analysis of the proposed scheme is applied to the Bryllite consortium blockchain system (homed in Hong Kong), which is a new blockchain network developed for international game industries, gamers, and game events.
Sports Scientific Approach for Martial Arts Development
Jusik Park,Kijin Kim,Jaehoon Kim J-INSTITUTE 2022 International Journal of Martial Arts Vol.7 No.1
Purpose: Martial arts can be related to the scientificization of the sporting process in the case of the body and the scientificization of the mind in the case of the mind, considering the two major flows of training the body and mind. Method: Scientificization related to physical training can promote future-oriented sports science with activa-tion of convergence based on existing sports science, and cultivation of the mind can suggest scientificization to pursue new areas of philosophical thinking and the spiritual world. Therefore, based on the holistic training for the training of body and mind, it is made up of an academic approach for comprehensive scientificization. In the course of attempts for academic development and social contribution, various fields of science are promoting field-oriented basic guidelines, systematic review, high-level technology and qualitative evaluation, along with efforts to find evidence-based principles. Results: Martial arts activities are carried out in the form of sports activities, promoting optimization and maximization of physical fitness and technical factors, and are based on related physiology, nutrition, epidemiology, psychology, sociology, motor control and learning. In addition, the academic approach of sports science, including the physical conditioning and training theory of athletes, and industrial and environmental engineering related to efficient facilities, equipment, implement, and environment, will be the main content. Conclusion: The scientific approach for the future-oriented activation of martial arts requires the establishment of an intensive scientific support system for concrete scientificization in terms of the practical value and utilization of martial arts activities based on the establishment of academic identity. In addition, for the science of martial arts, it is necessary to promote advanced convergence science, globalization centered on trends and popularity in Korea, systematic nurturing of research personnel related to martial arts sports, establishment of a cluster of martial arts sports-related infrastructure, and popularization and industrialization of martial arts sports.

Purpose: In this study, the number of students enrolled in the practical classes is decreasing as the academic year increases due to the reduction of required courses and the expansion of major electives in order to give stu-dents voluntary class options unlike in the past for Taekwondo students. Considering that as a result, physical strength and practical skills may decrease, this study intends to compare and analyze the differences by grade level by measuring the physique and physical strength of students enrolled in the Department of Taekwondo. In addition, the results of this study are intended to be used as basic data for organizing and reorganizing the curriculum by grade level. Method: The subjects of this study were Taekwondo majors enrolled at K University in D city, 27 first graders, 26 second graders, and 26 third graders (total 79), and the characteristics of body composition and physical fit-ness factors were compared and analyzed. Results: As a result of body composition measurement, body fat percentage and body mass index were statis-tically significantly higher in second grade than in first grade. As a result of measuring the physical fitness factors, it was found that the first graders were statistically significantly higher than the third graders in the Harvard Step test, which is an evaluation item for cardiorespiratory endurance. The sound reaction time was found to be statis-tically significantly faster in the first year students than in the second year students. The stand-up long jump, which is a quickness evaluation item, was statistically significantly higher in first-year students than in third-year students. Conclusion: In conclusion, it is considered that the decrease in the frequency of use of the practical practice space and face-to-face classes in the university due to COVID-19 had a negative effect on the physical composi-tion and development of physical fitness of Taekwondo students. Based on the results of this study, it is thought that it is necessary to seek ways to improve the physical strength and practical ability of Taekwondo students.
Valperga: Mary Shelley's Search for Ungendered History
Jusik Park 19세기영어권문학회 2008 19세기 영어권 문학 Vol.12 No.2
Having in mind how she creates a topography of gender that serves as a vehicle for critiquing prevailing masculine concepts of history, this paper examines Mary Shelley’s second novel Valperga from the standpoint of the complex relationship between history and gender and tries to explore the ways in which she incorporated it into her hybrid narrative form. First, we shall see how Shelley reproduces the ideology of her literary culture by melding the conventionally masculine genre of history with the culturally feminized sentimental novel of the period and how, by rejecting both extremes, she adopts a hybrid, ungendered narrative form for her novel. We will also see, in so doing, how Shelley advocates a new feminist history that is more than a simple rejection of masculine values in favor of the feminine. Instead, the new historical model that powerfully emerges in Valperga through the combination of Euthanasia as the moral center and the hybrid form of the novel itself is one which recombines separate gender categories into a single and unified whole that retains the qualities of each. Finally, we will see how Valperga confirms itself as a text that has essentially “ungendered” its own form, especially though the interaction of history and fiction, which undercuts the gendering of these literary forms,. That is, this paper asserts that by integrating the masculine and the feminine, the hybrid text of Valperga formally reinforces the underlying ideology of the novel, which, in keeping with the ideology of many women writers of the Romantic period, resists a model of oppositional polarity.
Jusik Park,Wookwang Cheon J-INSTITUTE 2020 Kinesiology Vol.5 No.2
Purpose: This study compared the characteristics of body composition, physique, physical fitness factors, and isokinetic muscle function by grade in middle school soccer players. Method: The results of analyzing differences in body composition and physique, physical fitness factors, and isokinetic muscle function by grade(38 in 1st grade, 46 in 2nd grade, 21 in 3rd grade) targeting 105 soccer players in S city middle school are as follows. Results: Body composition and physique factors there were significant differences by grade in height, weight, upper limb length, lower limb length, sitting height, and arm span. The post-verification of the main effects showed that height and weight were significantly higher for the second and third graders than for the first graders. For upper and lower limb length, the third graders were significantly longer than the first graders, while for sitting height, the second and third graders were significantly higher than the first graders. Fingertips were found to be significantly longer in the third graders than in the first and second graders. In physical strength factors, back muscle strength, grip strength, push-ups, sargent jump, standing long jump, side steps, shuttle run, and trunk forward flexion, trunk backward flexion, visual perception reaction, lung capacity showed significant differences by grade. As a result of post-hoc verification of the main effects by grade, the second and third graders were significantly higher than the first graders in back strength, grip strength(left, right), push-ups, and standing long jump. Sargent jump and side steps were found to be significantly higher as the grade increased, and shuttle run, visual perception reaction, and lung capacity were significantly higher for the third graders than for the first graders. Com-pared to the first and second graders, the third graders were significantly higher in trunk forward and backward flexion. In isokinetic muscular functions measured at 60 degrees of angular velocity, there were significant differences by grade in left extensor per weight(%BW), right extensor(Nm), left extensor(Nm), left flexor per weight(%BW), right flexor(Nm), and left flexor(Nm). As a result of the post-hoc verification of the main effects by grade, the third graders were significantly higher than the first graders in left extensor per weight(%BW), and the second graders were significantly higher than the first graders in right extensor(Nm), left extensor(Nm), left flexor per weight(%BW), right flexor(Nm), and left flexor(Nm). Conclusion: Based on the results of this study, the body composition, physique, physical strength factors, and isokinetic muscle function of middle school soccer players differed by grade, and considering that the less than four years of their career during the fast-growing period, the results of this study should be fully reflected in the planning of the training program.
DNA polymerase β deficiency in the <i>p53</i> null cerebellum leads to medulloblastoma formation
Kim, Jusik,Kim, Jaemi,Lee, Youngsoo Elsevier 2018 Biochemical and biophysical research communication Vol.505 No.2
<P><B>Abstract</B></P> <P>Defects in DNA damage response or repair mechanisms during neurogenesis result in genomic instability, which is causative for several neural defects. These include brain tumors, particularly medulloblastoma, which occurs in the cerebellum with a high incidence in children. We generated an animal model with defective base excision repair during brain development through selective inactivation of DNA polymerase β (<I>Polb</I>) in neuroprogenitor cells. All of <I>Polb</I> conditional knockout mice developed medulloblastoma in a <I>p53</I> null background, similar to the <I>Xrcc1</I> and <I>p53</I> double deficient animal model. XRCC1 is a scaffolding protein which is involved in DNA damage repair and binds to POLB. In both animal models, the histopathological characteristics of the medulloblastoma were similar to those of human classic medulloblastoma. Brain tumor development was slower in the <I>Polb</I> and <I>p53</I> double null animals than in the <I>Xrcc1</I> and <I>p53</I> double knockout animals. Molecular marker analysis suggested that <I>Polb</I>- and <I>Xrcc1</I>-deficient medulloblastomas belonged to the SHHα subtype, underscoring the important role of genomic stability in preventing this devastating pediatric cerebellar tumor.</P> <P><B>Highlights</B></P> <P> <UL> <LI> DNA polymerase β inactivation leads to medulloblastoma formation in the <I>p53</I> null cerebellum. </LI> <LI> The DNA polymerase β null medulloblastoma is histopathologically similar to human medulloblastoma. </LI> <LI> DNA polymerase β and <I>Xrcc1</I> null medulloblastomas show the characteristics of the SHHα subtype. </LI> </UL> </P>
