  • Colin Rowe was an important historian, theorist and critic in Modern architecture. His significance in Modern architectural history lies in not only historiography which has changed our view of Modernism but deep theoretical involvement in practice. This study is a critical review and analysis on his formalist approach in Architecture. With a view that his position of formalist has indispensible relationship with liberalism from K. Popper's critical rationalism, this study try to show how his philosophical background has an influence upon his way of seeing architecture, history, form, urbanism, and meaning, etc. And this study also try to explain why the principle of architecture as an autonomous discipline which is the main point of view in Rowe's criticism has been so successful and influential. This study also explain what is the possibility and limitation of Rowe's formalist approach and way of reading buildings. His intelligent way of formal analysis can give us new understandings of how the form generates and the process of design goes on. Furthermore it guide us a new horizon of architecture as a language game. Since his early writings showed both side of formalist approach in architecture and it didn't changed a lot. We can understand his 'Collage City' was a his final answer to his formalist way of making architecture and urbanism. we can estemate it as a utopia without utopianism and an ideology without ideological color.

  • The paper deals with the flutter of a cantilevered beam subjected to a rocket thrust generated by a solid rocket motor. It is saaumed that the rocket thrust is to be a constant follower thrust, and produced by the installation of a solid rocket motor to the tip end of the cantilevered beam. The rocket motor is considered to be a rigid body having finite sizes, but not a mass point as it has been assumed so far. Governing equations are derived through the extended Hamilton's principle, and finite element method is applied to obtain the theoretical prediction for critical follower thrust. The maximum follower thrust is also calculated through the change of shear deformation parameter of the beam in the numerical simulation. The theoretical prediction for flutter or stability is verified by experiment. The experimental results show that critical follower thrust in theory agrees well with the experimental value taking account of the magnitude, rotary inertia of the rocket motor and the distance from the tip end of the beam to the center of gravity of the rocket motor.

  • Microblog is emerging as a new communication service because of its usefulness and real-time accessability. Recently, microblog services, such as twitter and me2day in Korea, are getting a great attention. Continuous use intention is critical to sustain the service. However, most recent studies are based on Technology Acceptance Model(TAM) and Expectation Confirmation Model(ECM). These models are only focused on individual factors and overlook social influence factors. Social influence has been indicated as a critical factor of technology adoption and diffusion in social context(Davis, 1989; Fulk et al., 1987). In this study, we explore factors related to social influence which effect on continuous use intention for 'me2day' that is one of the most famous microblog in Korea. The purpose of this study is to understand continuous use intention and examine the relationship among social influence factors, social presence, and continuous use intention. To understand the phenomenon of continuous use intention in microblog service, this study employed social influence theory and expanded it by adding personal network exposure and group norm as additional social influence factors. The results show that social identity, group norms, and social presence positively influences continuous use intention. Contrary to our expectation, personal network exposure does not influence on continuous use intention. Academically, this research can contribute to microblog research field through elucidating the relationship among social influence factors, social presence, and continuous use intention. Although there is not enough research which is considered social influence factors as major explanation for continuous use intention, this study can give novel point of view to understand continuous use intention of microblog. Practically, service providers could consider ways to encourage users to continually use microblog service by reinforcing social influence factors and social presence.

  • Purpose : This study aimed to examine the item characteristics of the Korean version of the intensive care experience questionnaire (K-ICEQ) using the Rasch analysis model of the item response theory. Methods : In this methodological study, the validity of the scale was examined, and a secondary analysis was conducted using cohort data of patients who were discharged from the intensive care units (ICU). Data from 891 patients who responded to the K-ICEQ upon ICU discharge were analyzed. The WINSTEP program was used to analyze item characteristics, including item difficulty, fit indices, appropriateness scale, and separation reliability. Results : The difficulty level of all 26 items of the K-ICEQ was appropriate, and the fit indices of the 25 items, except for item 18, were good. The 5-point scale of the K-ICEQ was not appropriate in the three subscales. The item separation reliability was good in all subscales, but did not meet the criteria in terms of respondents. Conclusion : The results of examining the item characteristics of the K-ICEQ revealed a good degree of difficulty, fitness, and item separation reliability. To increase the validity of the K-ICEQ, we suggest the rearrangement of the overall item order, modification of the item description of the "recall of experience" subscale, and reduction of the scale response level.

  • With the fast development of complex science, lots of social networks are studied. We know that the social network is widely applied in analyzing issues in human culture, economics and web sciences. Recently we witness that some researchers began to compare the social network constructed from fiction literatures(literature social network) and the real social network obtained from practice. But we point that previous approaches for literature social network have some drawbacks since they completely depend on the biographical dictionary constructed for a designated literature. So since the previous approach focus on the few important characters and peoples around them, we can not understand the global structure of all characters appeared in the literature at least once. We propose one method to extract all characters appeared in the literature and how to make the social network from that information. Also we newly propose K-critical network by applying frequency of the named characters and the strength of relationship among all textual characters. Our experiment shows that the K-critical measure could be one crucial quantitative measure to compute the relationship strength among characters appeared in the object literature.

  • The purpose of this thesis is to understand Henry Jame's theory of the novel and to clarify the importance of him as a theorist. He developed many literary techniques through his dozens of works. But it is more important that he is a theorist who established the unique theory of novel through his critical essays. I arranged Jame's early theories, focusing on "The Art of Fiction" that was one of his major essays written in 1884. His main idea was that the purpose of novel was to represent life. The "experience" that James emphasized was composed of characters, impression and consciousness. "Psychological Realism", which is Jame's unique realism, reflected his interests in the inner mind of man. James believed in the capacity of human imagination as the source of creative inspiration and its ability to perceive reality in a manner that is more intense and comprehensive and transform it into a more balanced and orderly ideality. Henry James always insisted on the importance of writer's imagination. Another important imagination in Henry Jame's novel is the character's imagination. It is closely related with the consciousness, the heart of the Jame's literary world. James devised the new form of novel as well as the possibility of representation of mind. At this point, it is said that James was the pioneer of literary criticism. He evoked the trend of the early 20th century.

  • Two thermodynamic models were used to predict the partial molar volumes of solutes in supercritical carbon dioxide at infinite dilution: (1) the Peng-Robinson equation of state with various mixing rules including those based on $EOS/G^E$ (2) the Kirkwood Buff fluctuation integral with the hard sphere expansion (HSE) method. The Kirkwood-Buff fluctuation integral method, in which an equation of state for pure component and molecular parameters are required, produced better results especially near the critical point than the Peng-Robinson equation of state with the several mixing rules based an $EOS/G^E$. When the $EOS/G^E$ mixing rules were used, poorer results were obtained compared with the classical mixing rule and Kirkwood-Buff model.

  • Wang-ch'ung(왕충) negated the theory of efficacy between the Heaven and a Man(천인감응) based on Yin Yang(음양) and Five Elements(오행) that was popular at that time. The Heaven is just solid one without a mouth and ears. The order of nature is circling in its own way regardless of the will of human being. Jung classified psychological types of the human being into the introversion and extroversion. From this point of view, Wang-ch'ung(왕충) is belong to extroversion philosophy. He criticized modern society by using effect and evidence, and expressed it as critical moral philosophy and political ideal.

  • The theories of Korean Public Art originated by the artists who were against dictatorship and they associated with democratic politicians. They criticized the Fine art that were supported by the dictatorship and gave their efforts for restoration of 'resistance paintings(against dictatorship)', 'proletarian painting', 'realism painting'. In addition, they participated new social ideology(democracy) movement and demonstrated for their rights in arts. These became the main kernel the public art theory was initiated. The public artists splitted into several different parts and participated in the democratic social movement as well as the art movement for freedom. They opened various art exhibitions within different genre, diverse space for various art section such as an exhibition hall, a factories, a university, or a congregation square. Furthermore, the public art theorists published their divergent views through newspaper/broadcasting or unauthorized printed materials. Most of the public artist and the theorists kept their relationship strongly until 1985, the time when 'National Arts Association' started. In 1983 and 1984, they were clearly separated into two parts; artists(move only in art museums) and activists(move in public spaces like school, convention square etc). Their ideological separation also took out national problems. The division; professional artists and armatures, became the social issue as a social stratification matter. And in creating method, there are also other conflicts; critical realism, and public realism as well as western painting and traditional one. These kinds of separation and conflicts made different Public artists associations, under divergent names; 'Reality and Speak'(R&S), 'KwangJu Art Association', 'Durung', 'Dang(Land)', and 'Local Youth Students Association'. In addition, their ideology and pursuit toward art movements were very difference. However, the differences and conflicts weakened When the oppression of democratic education from new dictatorship(Pres. Jun, Doo Hwan) came out. In August. 1985 the government opened to the public so called, 'The draft of School stabilization law'(Hankwon Anjung Bup) to control the teachers' rights and that initiated bigger street demonstration and conflicts between police and educators. In November.1985, assembly meeting of National Arts Association in democracy opened as 'ONE' combined organization. In this presentation, I'd like to summarize the stream of art movement until 1984, and clarify the main art theories that lead the Public Art Movements in 1980s. The main theories in 1980s are crucial because they become the origin of public art theories. This presentation started with O,youn's "Hyunsil Dong In the first declaration" and explained the absent of practice in 1970s. In addition, Won, Dong Suk 's theory was mentioned as all over struggles in theories before 1980s. GA and R&S 's founding declarations in 1970s were the start of public art theorists' activities and this article reported the activities after the declarations. First, realism base on the consciousness of reality. Second, practice art democratization based on the ideology. Third, the subject of public art movement based on understanding people's social stratification structure. Fourth, the matters of national forms and creative ways in arts based on showing reality. Fifth, the strong points in arts that the practitioners accepted. About the public art theories around 1984, I discussed the dividing point of public art theories that were shown in 'generation theory', 'organization theory', and 'popularization theory' by the practitioners. The public realism theory that subjects the contradiction of reality and point out the limits of critical realism not only showing the new creative ways but also giving the feeling of solidarity to the public art activist groups. After that, public art movements expressed 'Dismentlement of Capitalism' and 'Public revolution'. In addition, the direction of public art movements were established strongly. There were various opinions and views during the start and formation of the public art theories. The foundation of theorists activities derived from the practitioners who had the concept based on stratification and nationalism. The strong trend of group division spreaded out by practitioners who opened art work together in factories, universities, squares and rural areas. Now many lively active practitioners are gone to the other field not related with arts, and others join into professional art field not public art one with unknown reason. The theorists have the same situation with the practitioners. It means to me that theory always have to be based on the practice.

  • The advancement of medical technology has made it possible to treat various incurable diseases. Especially organ transplantation can give another life to the patients who have organ failure and could not find any other ways to treat their diseases. According to the development of medical technology and immunosuppressive drugs, the rate and extent of organ transplantation is increasing these days. New medical technologies like organ transplantation brought on critical issues and these have changed the way of thinking and morals that has been the fundamental rules in our society. Bioethics is already an important field of medicine and oriental medicine should investigate the problem caused by the development of medical technology and life science and should form a view of life in oriental medicine. Oriental medicine is East Asian traditional medicine based on "Huangdi-Neijing", constructed by the system of Jangfu and meridian. The traditional therapies of oriental medicine have completed a scientific system on the point of view that looks on human and nature equally. This process continued to form a new medical theory as the environment was changed and the new diseases were appeared since "Huangdi-Neijing" and "Shoganron" showed a new scope to investigate human and diseases. Therefore, it is important to develop the point of view of oriental medicine as the medical situation was changed. Oriental medicine has a holistic view that considers human as a little cosmos resonated by a big cosmos and regards the possibility to recover and to regulate the energy in our body. This theory is a basic idea of oriental philosophy. Oriental medicine focuses on the balance of yin and yang of the body and tries to harmonize the imbalance of yin and yang caused by the life style and environment. This can solve many problems that cannot be settled by modern medicine and this can accomplish the new paradigm of oriental medicine that is needed these days.
