  • There have been researches on game continuance intention based on consumer behaviour theory of management science. Such macro access of computer game analysis might be insufficient to draw valuable results due to complex subsystem structure of recent computer games. In this paper, we choose 'Blade and Soul' game that was first published in 2012 and has been within top 20 MMORPG in Korea but known as a 'long time users' only game'among game players recently. Three user groups - long loyalty, concentrated, casual - are classified based on their play history and play time per day of Blade and Soul. The first survey with 222 subjects revealed that the real strength of the game was not the combat - Dungeon, Arena, Battleground competition - but very cohesive game community Blade and Soul has. Thus, we conduct another survey on the game community issues among 148 long time users (over 3 years playing history) and analyze their traits and behaviour patterns.

  • The study of popular music in Korea has been looked down on in terms of its academic value, which has led to the demise of research into this topic. Unlike classical music, all areas of study of pop music (history, theory, and performance) in Korea inevitably rely on curriculums and courses in foreign countries. This study focuses on the era of the Eighth U.S. Army when modern band music first arose in Korea to discuss the important role played by Shin Joong Hyun's Psychedelic music style. Shin Joong Hyun's new approach to arranging and harmonizing included the qualities of Western music, but kept the melody lines of our own traditional style. Shin Joong Hyun's music is still being played by today's musicians decades later and it definitely deserves to be praised for generations to come. Although this study only covers a limited portion of our pop music history, its purpose is to provide future generations of musicians with knowledge on the roots of our pop music culture.

  • The system-based approach is needed to select an optimal mix of weapon systems and ship platform among a variety of design alternatives with the uncertainties of the initial required operational capability. In the early-phase design, which included a feasibility study and concept design, it is possible to cause problems when a review of the operational concept, database development, and systematic design are not done, thereby producing uncertain and unstable requirements. To select the best solution without trial-and-error, the U.S. navy has applied the set-based method for the early-phase design of a new ship-to-shore connector. The ship synthesis model plays an important role in applying the set-based method, but only a few countries possess this model and have prohibited this model from being transferred to other countries. This paper suggests a set-based method using a genetic algorithm and decision-making theory through benchmarking existing ship data. The algorithm was verified using the DDG-51 class ship synthesis model to optimize the weapon system design, which has been released for research purposes.

  • GHX (Geothermal Heat Exchanger) design which determines the performance and initial cost is the most important factor in ground source heat pump system. Performance of GHX is strongly dependent on the thermal resistance of soil, grout and pipe. In general, GHX design is based on the static simulation program. In this study, dynamic simulation has been peformed to analyze the variation of system performance for various GHX parameters. Line-source theory has been applied to calculate the variation of ground temperature. The averaged weather data measured during a 10-year period $(1991\sim2000)$ in Seoul is used to calculate cooling and heating loads of a building with a floor area of $100m^2$. The simulation results indicate that thermal properties of borehole play significant effect on the overall performance. Change of grout thermal conductivity from 0.4 to $3.0W/(m^{\circ}C)$ increases COP of heating by 9.4% and cooling by 17%. Change of soil thermal conductivity from 1.5 to $4.0W/(m^{\circ}C)$ increases COP of heating by 13.3% and cooling by 4.4%. Change of GHX(length from 100 to 200 m increases COP of heating by 10.6% and cooling by 10.2%. To study long term performance, dynamic simulation has been conducted for a 20-year period and the result showed that soil temperature decreases by $1^{\circ}C$, heating COP decreases by 2.7% and cooling COP decreases by 1.4%.

  • The main aim of this study is to identify the role of information dissemination on urban and rural citizens of Bangladesh during the COVID-19 pandemic and the role of misinformation in this process. The study also aimed at finding appropriate counter misinformation strategies regarding COVID-19. An online questionnaire was prepared to collect the viewpoints of the urban and rural citizens of Bangladesh regarding dissemination of information during COVID-19, misinformation regarding COVID-19, and counter misinformation strategies. Along with demographic and general information, a five-point Likert scale was used to measure COVID-19 related misinformation beliefs and how to counter them. Chi square tests were used to determine the association between current residency, information sources, the importance of information dissemination, reactions after getting COVID related information, and evaluative steps after getting information and before disseminating it. Additionally, nonparametric Mann-Whitney U and Kruskal-Wallis tests were conducted to know the significance of difference in respondents' assessment on COVID-19 related misinformation in terms of their demographic characteristics. Cronbach's alpha score was obtained to see the reliability of the questionnaire items. The current study reveals that both urban and rural citizens of Bangladesh are influenced by information dissemination regarding COVID-19 and they have lower level of misinformation belief. The respondents have differences in misinformation belief by different demographic groups. Respondents' educational status, information literacy, sources of getting information, and evaluative steps after getting information have significant differences in misinformation belief. The study also noticed the support of respondents for countering misinformation strategies regarding COVID-19.

  • Ian Watt, author of The Rise of the Novel, maintained that the novel originated in modern England, came from prose discourses such as the news, political essays and journalistic writing which propagated the Enlightenment, and the novels represent formal realism. The main point of this paper is to examine Watt's theory of the rise of the novel on the basis of the criticism of antinomy of the Enlightenment and "the public sphere" in Habermas' terms. At first, I will criticize formal realism, which is not a new literary species, but a formally renovated realistic form that represented capitalism and protestantism. And, then, I will show that formal realism is a kind of antinomy because it turned away from the voices and reality of the low-class and women though the novel concentrated on common people, not the aristocrats. Secondly, I will inquire into the antinomy of the Enlightenment in the aspects of reason, freedom, individualism and women. In my view, as soon as the high-middle class acquired their political rights, these values were no more encouraged and the result revealed antinomy of the Enlightenment more explicitly. Thirdly, I'd argue that "the public sphere" had positive meanings to everyone when the bourgeosie were fighting against the Absolutism and the aristocracy. I'll also insist that the high-middle class and the intellectuals were in "the public sphere" in which Habermas argues that rationality and equality were thought to have been realized, while the low-middle class and most women were de-enlightened and disciplined by reading the novel privately. In conclusion, formal realism is not the rise of the novel, but the opening of the novel peculiar to bourgeosie parliamentarism from the middle-eighteenth century to the middle-twentieth century.

  • The essay discusses the way in which the aesthetic of Pre-Raphaelites reformulates the habitual system of knowledge in the Victorian age by adapting $Ranci{\acute{e}}re^{\prime}s$ concept of aesthetics. $Ranci{\acute{e}}re$ develops an original theory of aesthetics, a regime of knowledge which enables to perceive and reflect art as such. In this way, aesthetics turns to be the logical system by which the consensus idea of the beautiful comes to exist. For $Ranci{\acute{e}}re$, aesthetics is an agreed system of the sensible and reproduces the habitual knowledge of the world. Therefore, a new aesthetic movement means an attempt to break the given aesthetics and reorients the new distribution of the sensible. The important point of $Ranci{\acute{e}}re^{\prime}s$ argument is that he does not presuppose the dimension beyond the present unlike Frankfurt School. What $Ranci{\acute{e}}re$ claims is that there is no such the aesthetic which can correct the instrumental reason, but rather an indifferent moment in which a worker finds out himself as a creator who can give rise to the new regime of the sensible and feels free from what he must work for. From this perspective, the essay explores the aesthetic of Pre-Raphaelites and its meaning in nineteenth century Britain. Pre-Raphaelites was an artist group who railed against a so-called academic style of paintings and created a new aesthetic criterion to describe the truth of the natural world. The essay examines the interrelationship between Pre-Raphaelites and photography that would enable them to re-distribute the sensible and produce a new way of seeing the order of things. This is related to the birth of a modern gaze as in the case of landscape paintings. What is crucial is that the distribution of the sensible is always-already doubled with the political. In short, Pre-Raphaeltes is not only an aesthetic movement but also a political pursuit to achieve a disenchanted perception of nineteenth century industrial capitalism.

"Gerontion" and The Waste Land: Why Did Eliot Intend to Make "Gerontion" a Preface to The Waste Land? (『황무지』와 「게론티온」-왜 엘리엇이 「게론티온」을 『황무지』 서시로 사용하려 했었나?)

  • Eliot's The Waste Land represents the last century in many respects. While working on the poem in cooperation with Pound, Eliot intended to make "Gerontion" a prelude in The Waste Land. But, as we read in his letter to Eliot, Pound advised him against it. As a result, Eliot had excluded it from The Waste Land. "Gerontion" was published separately, as an independent poem. Between "Gerontion" and The Waste Land, we find that the theme and the techniques are very much alike. However, for this very reason Eliot and Pound must have had thought differently. Eliot must have thought that "Gerontion" would serve well as a preface to the long poem, The Waste Land. It will provide a good introduction to the long poem, he may have thought. In the meantime, Pound must have thought that such similarities in theme and techniques would weaken both works, which would be redundant. To Pound, it would be too much to have the summary of everything that is to be repeated in The Waste Land. Eliot intuitively followed Pound's judgment. Both "Gerontion" and The Waste Land have similarities in theme and techniques. The theme of both works is "aimlessness, spiritual sterility, barrenness" in modern man living in the waste land. For example, in "Gerontion," there appear an old man Gerontion, Mr. Silvero, Hakagawa, Madame de Tornquist, Fraulein von Kulp, who are representative of spiritual barrenness of modern world; in the same context, in The Waste Land those who are most representative of modern world are the Typist, clerk, Thames's daughters, Madamn Sosostris, Tiresias, Phelabas. And in terms of techniques, "Gerontion" and The Waste Land both use dramatic monologues, allusions, and the techniques of modern art, such as montage and mosaic. Here in these works Eliot in fact practises his theory of the "Objective Correlative" that he has invented.

  • The discovery of biomarkers related to pattern identification (PI), the core diagnostic theory of Korean medicine (KM), is one of the methods that can provide objective and reliable evidence by applying PI to clinical practice. In this study, 40 diabetic patients and 41 healthy control subjects recruited from the Korean medicine clinic were examined to determine the human electrical response related to the deficiency pattern, a representative pattern of diabetes. Qi-Blood-Yin-Yang deficiency pattern scores, which are representative deficiency patterns for diabetes mellitus, were obtained through a questionnaire with verified reliability and validity, and the human electrical response was measured non-invasively using a bioimpedance meter. In ANCOVA analysis using gender as a covariate, the 5 kHz frequency resistance and 5-250 kHz frequency reactance were significantly lower in the diabetic group than in non-diabetic control group. In addition, the multiple regression analysis showed a positive correlation (R2=0.11~0.19) between the Yang deficiency pattern score and resistance value for the diabetic group; the correlation was higher at higher frequencies of 50kHz (R2=0.18) and 250kHz (R2=0.19) compared to 5kHz(R2=0.11). In contrast, there was no such significant association in the control group. It implies that bioimpedance resistance measured at finite frequencies may be useful in predicting Yang deficiency, which is closely related to diabetic complications by reflecting the decrease in body water content and metabolism. In the future, large-scale planned clinical studies will be needed to identify biomarkers associated with different types of PI in diabetes.

  • Earthquake Resistant Design Philosophy seeks (a) no damage, (b) no significant structural damage, and (c) significant structural damage but no collapse of normal buildings, under minor, moderate and severe levels of earthquake shaking, respectively. A procedure is proposed for seismic design of low-rise reinforced concrete special moment frame buildings, which is consistent with this philosophy; buildings are designed to be ductile through appropriate sizing and reinforcement detailing, such that they resist severe level of earthquake shaking without collapse. Nonlinear analyses of study buildings are used to determine quantitatively (a) ranges of design parameters required to assure the required deformability in normal buildings to resist the severe level of earthquake shaking, (b) four specific limit states that represent the start of different structural damage states, and (c) levels of minor and moderate earthquake shakings stated in the philosophy along with an extreme level of earthquake shaking associated with the structural damage state of no collapse. The four limits of structural damage states and the three levels of earthquake shaking identified are shown to be consistent with the performance-based design guidelines available in literature. Finally, nonlinear analyses results are used to confirm the efficacy of the proposed procedure.
