  • This paper proposes geographical name denoising by machine learning of event detection based on twitter. Recently, the increasing number of smart phone users are leading the growing user of SNS. Especially, the functions of short message (less than 140 words) and follow service make twitter has the power of conveying and diffusing the information more quickly. These characteristics and mobile optimised feature make twitter has fast information conveying speed, which can play a role of conveying disasters or events. Related research used the individuals of twitter user as the sensor of event detection to detect events that occur in reality. This research employed geographical name as the keyword by using the characteristic that an event occurs in a specific place. However, it ignored the denoising of relationship between geographical name and homograph, it became an important factor to lower the accuracy of event detection. In this paper, we used removing and forecasting, these two method to applied denoising technique. First after processing the filtering step by using noise related database building, we have determined the existence of geographical name by using the Naive Bayesian classification. Finally by using the experimental data, we earned the probability value of machine learning. On the basis of forecast technique which is proposed in this paper, the reliability of the need for denoising technique has turned out to be 89.6%.

  • Purpose: Scalp avulsion is a life-threatening injury that may cause trauma to the forehead, eyebrows, and periauricular tissue. It is difficult to treat scalp avulsion as it may lead to severe bleeding. Therefore, emergency scalp replantation surgery is necessary, and we must consider the function, aesthetics, and psychology of the patients. A case of scalp avulsion leading to massive bleeding was encountered by these authors, which led to a failure to achieve the proper operation conditions in an adequate time period. Methods: A 49-year-old female was hospitalized due to having had her head caught in a rotatory machine, causing complete scalp avulsion which included the dorsum of the nose, both eyebrows, and ears. Emergent microsurgical replantation was performed, where a superficial temporal artery and a vein were anastomosed, but the patient's vital signs were too unstable for further operation due to excessive blood loss. Three days after the microanastomosis, venous congestion developed at the replanted scalp, and a medicinal leech was used. Leech therapy resolved the venous congestion. A demarcation then developed between the vitalized scalp tissue and the necrotized area. Debridement was performed 2 times on the necrotized scalp area. Finally, split-thickness skin graft with a dermal acellular matrix (Matriderm(R)) was performed on the defective areas, which included the left temporal area, the occipital area, and both eyebrows. Results: The forehead, vertex, right temporal area, and half of the occipital area were successfully replanted, and the hair at the replanted scalp was preserved. As stated above, two-thirds of the scalp survived; the patient could cover the skin graft area with her hair, and could wear a wig. Conclusion: Complete scalp avulsion needs emergent replantation with microsurgical revascularization, but it often leads to serious vital conditions. We report a case with acceptable results, although the microanastomosed vessel was minimal due to the patient's unstable vital signs.

  • Type 1 diabetes mellitus (T1DM) is a pathological condition associated with osteopenia. WNT/β-catenin signaling is implicated in this process. Trabecular and cortical bone respond differently to WNT/β-catenin signaling in healthy mice. We investigated whether this signaling has different effects on trabecular and cortical bone in T1DM. We first established a streptozotocin-induced T1DM mouse model and then constitutively activated β-catenin in osteoblasts in the setting of T1DM (T1-CA). The extent of bone loss was greater in trabecular bone than that in cortical bone in T1DM mice, and this difference was consistent with the reduction in the expression of β-catenin signaling in the two bone compartments. Further experiments demonstrated that in T1DM mice, trabecular bone showed lower levels of insulin-like growth factor-1 receptor (IGF-1R) than the levels in cortical bone, leading to lower WNT/β-catenin signaling activity through the inhibition of the IGF-1R/Akt/glycogen synthase kinase 3β (GSK3β) pathway. After β-catenin was activated in T1-CA mice, the bone mass and bone strength increased to substantially greater extents in trabecular bone than those in cortical bone. In addition, the cortical bone of the T1-CA mice displayed an unexpected increase in bone porosity, with increased bone resorption. The downregulated expression of WNT16 might be responsible for these cortical bone changes. In conclusion, we found that although the activation of WNT/β-catenin signaling increased the trabecular bone mass and bone strength in T1DM mice, it also increased the cortical bone porosity, impairing the bone strength. These findings should be considered in the future treatment of T1DM-related osteopenia.

  • While there were separation, confrontation and conflicts in Yungnam confucian group in seventeenth century, Nampa Jang Hak(1614~1669), was one of the representative figure among Yeoheon's pupils in doing the project of Yeoheon's enshrinement and strengthening the solidarity of Yeoheon's students. His family had close relationship with Yeoheon, and he started to receive instructions from Yeoheon in his early ages. Owing to the close relationship with Yeoheon, Nam pa did the leading role in the memorial projects, such as publishing the collection of works, and enshrining Yeoheon's tablet in Seowon, a private academy. Especially, he defined Yeoheon's scholarstic mantle as 'assertion that does not come from the teacher whom specifies(不由師承論)' and tried to link Yeoheon's work with other confucian saints' works. This linkage functioned as a stepstone for the projects of enshrining Yeoheon in the memorial hall of their private school, Seowon. Accordingly, in this paper, Nampa's life and academic activities are investigated, considering he was in the middle of the turmoil of separation and conflict of Yeongnam confucian group. Specifically, Nampa was most actively involved in the project of enshrining Yeoheon, and he defined Yeoheon's scholaristic mantle as 'assertion that does not come from the teacher whom specifies(不由師承論)'. Basing on this understanding, he pushed ahead the controversial project of enshrining Yeoheon's tablet in Imgo Seowon(臨皐書院). Although Nampa's scholaric key concepts cannot be found clearly, he tried to diffuse Yeoheon's academic thought over other regions, and by this activity, he tried to solidify Yeoheon's scholarstic achievement and status. His activity confirms that he was most distinctive student of Yeoheon. Ultimately, He was the central figure of late times of Yeoheon school, comparing to the most prestigious fifteen scholars(樑頌十五賢) and ten scholars(旅門十哲) who represented the early times of Yeoheon school.

  • Harold Pinter's One for the Road(1984) is a play about violence. Nicholas, who appears to be the manager of a place, interrogates Victor, Nicky, and Victor's wife Gila in a room for one day from morning to night. There is no direct physical violence in this play. But hints about the atrocities that took place outside the stage make the audience guess the violence and cruelty. Violence, which is not seen as such, is the central theme of the play. One for the road is worth reading as a resistance to breaking the mirror of global ideology, not as it deals with violent events confined to Turkey. The problem which Pinter had in mind, in particular, is that the United States plays a leading role in producing world-class ideologies, and that Britain is involved in collusion with the United States in cultivating such ideological fantasies, both abroad and at home. This thesis analyzes the contrasting reactions of each character in the play based on this social context. In particular, the conflicting reactions of the characters on the system are the most important conflict in the drama. Nicolas is a manager who moves on the system without seeing the truth. Victor and his family, on the other hand, do not move within the same ideology as Nicholas. This paper will take a look at what their strategies of resistance is and how they are revealed in the work. In fact, Nicholas appears split. Nicholas seemingly reacted decisively to the interpellation of the system. He expresses his belief and respect for the legitimacy of his actions. However, he has repeatedly sought the respect and love of Victor. Nicholas is now swaying. The theme that Nicholas presents consciously by grabbing at his own sway is 'Patriotism.' But this fantasy splits through Victor's silence and death demands. Therefore, the questions to be answered are: So why does Nicolas appear to be torn apart in a system that directs violence? But why is he forced to assimilate into the system? What other figures imply? To answer these questions, this thesis will take Slavoj Zizek's view of ideology. On the other hand, there are previous studies that read the system of violence in One for the road from the Althusser's perspective. Surely, this play explores the role of Ideological State Apparatus. However, from the point of view of Althusser, it is not possible to read Nicholas's division and the point of resistance seen by Victor's family. Pinter does not limit the scope of the ideological system as a closed one that regenerates ideologies, but secures the domain of main body resistance and struggle. On the other hand, there are already several domestic theses that read Pinter's work in Zizek's perspective. But these theses are mainly focused on analysis of Mountain Language. What this thesis would suggest is that there is a potential for an ethical figure of Zizek to be considered in One for the Road.

  • Background: Since open Wiltse approach allows limited visualization for foraminal stenosis leading to an incomplete decompression, we report the short-term clinical and radiological results of unilateral biportal endoscopic foraminal decompression using 0 or 30 endoscopy with better visualization. Methods: We examined 31 patients that underwent surgery for neurological symptoms due to lumbar foraminal stenosis which was refractory to 6 weeks of conservative treatment. All 31 patients underwent unilateral biportal endoscopic far-lateral decompression (UBEFLD). One portal was used for viewing purpose, and the other was for surgical instruments. Unilateral foraminotomy was performed under guidance of 0 or 30 endoscopy. Clinical outcomes were analyzed using the modified Macnab criteria, Oswestry disability index, and visual analogue scale. Plain radiographs obtained preoperatively and 1 year postoperatively were compared to analyze the intervertebral angle (IVA), dynamic IVA, percentage of slip, dynamic percentage of slip (gap between the percentage of slip on flexion and extension views), slip angle, disc height index (DHI), and foraminal height index (FHI). Results: The IVA significantly increased from 6.24±4.27 to 6.96±3.58 at 1 year postoperatively (p = 0.306). The dynamic IVA slightly decreased from 6.27±3.12 to 6.04±2.41, but the difference was not statistically significant (p = 0.375). The percentage of slip was 3.41 preoperatively and 6.01 at 1-year follow-up (p = 0.227), showing no significant difference. The preoperative dynamic percentage of slip was 2.90; at 1 year postoperatively, it was 3.13 (p = 0.720), showing no significant difference. The DHI changed from 34.78 preoperatively to 35.05 postoperatively, which was not statistically significant (p = 0.837). In addition, the FHI slightly decreased from 55.15 preoperatively to $54.56%{\pm}9.86%$ postoperatively, but the results were not statistically significant (p = 0.705). Conclusions: UBEFLD using endoscopy showed a satisfactory clinical outcome after 1-year follow-up and did not induce postoperative segmental spinal instability. It could be a feasible alternative to conventional open decompression or fusion surgery for lumbar foraminal stenosis.

  • This research starts based on the assumption that the changes of educational system in China which had been caused by accepting western educational system in the late Qing Dynasty and the early Republic of China are indeed considered as a paradigm shift of educational system in China, This research aims first to investigate what kinds of problems and changes Chinese educational system confronted at that time and second to examine what kinds of implications such changes and problems of paradigm shift may have today in China. In order to achieve the goals of this research, I first researched changes and characteristics of educational paradigm shift occurred in the history of China. On the basis of those findings, I tried to analyze acculturation problems of Chinese educational system for that of western countries at that time, their implications in present time Chinese educational system, and the possibility of further paradigmatic shift in present Chinese education. In this paper, I assumed three historical paradigmatic shifts in educational system in China which had big influences on the foundation of Chinese education, such as the introduction of Confucian Thoughts, the introduction of Civil Examination System in Sui Dynasty, and lastly the introduction of western educational system in the late Qing Dynasty. The last paradigmatic shift occurred by the introduction of western education system into China was very different from the previous two paradigmatic shifts in China in that it was literally initiated by the world with cultures different from those of China, and that's why it is called Spatial Collision. It was also one of the many changes China had been forced to confront unvoluntarily. It was done for many other complicated factors such as the greed of western imperialistic countries, spreading of Christianity and missionary education, domestic resistance against long feudal reigning of Qing Dynasty, and lastly the intellect's eagerness for new knowledge and new ways of thinking. What is surely regretful for the paradigmatic shift of Chinese educational system was that it had been triggered by those many heterogeneous factors, thereby leading to such a sudden, entire and complete shift of Chinese education system. In addition, it was done without a deeper and further consideration of Chinese education system with thousand years of tradition. This situation could be understood to be an impetus strong enough to encourage the advent of a new paradigm propelled by rapid economic growth of China, many problems of western education system, reconsideration of Chinese tradition, and strengthening of women power in China, etc.

  • The article is a research about the Belle Epoque era and Dadaism in the modern culture as a whole and separate. The years from 1890s to 1914, is known as the Belle Epoque era, in which the European continent including France had developed the climax of the modern culture after the Renaissance. At the same time, it was the period where the postmodern developments were being spread, leading to the present days. Moreover, the main ideologies in art that led to the cultural advancement of the time were impressionism, cubism, art nouveau, evolutionized painting category, symbolism and futurism. It was a literature category that was maintained to present Dadaism and surrealism. Dadaism began since the magazine, Bulletin Dada was published, originating in 1916 by Tristan Tzara of Zurich, Switzerland during the WWI. The extreme motto that the Dadaists supported was a contradiction, as they had to dissolve from their own art movements and expression techniques. However, until Andre Breton introduced 'Manifeste du Surrealisme' in 1924, the "Dada group" had a tremendous influence in France as an epicenter and rejected the modern cause and art that continued during the time, thus attempting its dissolution. First, they rejected the ideology, ethics and customs of rationalism from the previous system and demonstrate an anarchical and anti-bourgeoisie characteristic. They also reject the French lucid thoughts and the artistic techniques. They strongly emphasized on their motto "The idea is created from the mouth", while reframing from the philosophical ideology and at the same time, attempting to express the psychical unconsciousness. Second, the most important catchphrase that the Dadaists supported was the theory of negation. The question "Why do you write?" connotes the negative consciousness about the artistic value and the stereotyped method of the preexisting writing and drawing. Third, the Dadaists bring forward a radical query about all of the former esthetic and morals, and reveal an admirable resistance spirit. They emphasized on the slogan "Dada, means nothing" and insist on 'the anti-literal Dada, anti-artistic Dada, anti-musical Dada'. The Dadaist movement manifested their resistant spirit and the new artistic spirit through the publication of , , and most importantly through the magazine . Fourth, the Dadaists embodied the volume, density, and quality into an image through the auto-technical, cubistic writings and drawings. They ignored the fixed form of arrangements, verses, and rhymes of a poetic diction. The Dadaists utilized an unfamiliar and inversed expression method of applying the combination of the size of print, or capital letters and lowercase letters, even combining printed and handwritten writings. As presented, the auto-technical and cubistic characteristic of expressing the auto-psychical ideology into writing is called as the radical aesthetic and moral and can be considered as the most essential cause of the Dadaists' avant-garde features. As a conclusion, Dadaism demonstrated dual characteristics of consuming the nutritive elements of the modern culture through the most powerful resistance and liberation of the artistic movement of the Belle Epoque era, where at the same time, it deconstructed the modern art. By revolting against the former grounds and expression techniques, and dominating the era with the new artistic spirit, their resistant actions were artistic movements that symbolized the dissolution of the modern times. Moreover, the Dada's expressionism and resistance of saying "There's nothing" can be evaluated as postmodernity's initiative of outweighing the modern history and opening the door for new period of nowadays.

  • In the early 20th century, Japan built theaters to take possession of colonial culture while establishing the Imperial University, libraries, and museums to accumulate and spread the knowledge of "imperial" Japan. Many different genres made a hit in theaters including theatrical troupes, theatrical companies, and motion pictures. One of the various features of expositions was "spectacles" or unusual events. They were integrated with a national festival in celebration of "5th anniversary of political commencement." In 1915, the longest hit series in Keijo (Seoul) was the dance performance by professional Japanese beauties and entertainers, whose songs delivered the legitimacy of governance. This study focused on the performance in the space of "cultural" spread called theaters, thus examining the "imperial" cultural waves they were in charge of. The study also focused on the tensional relations of Hierarchie along those cultural borders. The performance at the theater Engeikan(演芸館) in 1915 was especially an epoch-making event in the Japanese theatrical community of Keijo (Seoul): first, it marked the emergence of large-scale performance hall called Engeikan(演芸館); secondly, the performance kept its ongoing, stable streak for about 50 days; and it led to the appearance of leading troupes including Geijutuza(芸術座), which put on a show in Keijo (Seoul) in November, 1915. The study examined the issues of theater Engeikan(演芸館) performance in 1915 involving the art company, performance genre, and audience composition, showed that there was the coexistence of entertainment and governance through cultural ruling while securing amusement and entertainment, and found it was accompanied by the organized operation of "Keijo Sponsorship Council(京城協贊會)" which brought together the cultural capabilities of Japanese people living in Joseon. The performance at theater Engeikan(演芸館) in Keijo (Seoul) in 1915 fully reflected the issues involving the tensional relations between different artistic genres, the competing relations between the subjects of performance, and the cultural power.

  • This study provides a comprehensive survey of Post Keynesian economics. The global financial crisis 2008-2009 has triggered an important debate concerning economic theory, policy and methodology. The most important thing that this economic crisis has done for economics is that it revealed mainstream economics was wrong. Mainstream economics has been unable to offer clear answers for the crisis. The economic crisis, at the same time, brought about a crisis in the field of economics. This study suggests that economics needs to be altered into a new form that can explain the real world economy. In this paper, it is argued that Post Keynesian economics can be understood as the alternative economics. The paper begins with the vision and the origins of several Post Keynesian ideas, leading to an examination of certain features of the various groups, including their methodology and their approaches to uncertainty, their pricing theories and their growth theories. The focus, however, is on the stage reflected in Post Keynesian economics which is concerned with the conception of Lakatos's 'Scientific Research Programmes'. It is recognized that more research is necessary in order to complete the post keynesian economics as a standard science or as a progressive Scientific Research Programmes in economics.
