It is unfair that environmental pragmatism has been regarded as a mouthpiece for industrial expediency and business boosterism. John Dewey's radical pragmatism known as 'Instrumentalism' has provoked ecological fundamentalists' criticism more vehemently than any other pragmatic philosophies. However, most of the presumptive misunderstandings of such critics as Holmes Rolston, J. Baird Calliott, Erich Katz, C. A. Bowers and many others come from their limited or reduced reading of Deweyan pragmatism. The following three aspects of Deweyan pragmatism can work out in opening up a dialogical space with those eco-centrist thinkers mentioned above. First, the concept of Dewey's 'primary experience' can articulate the foundationalist view of nature, which is often found in aboriginal cultures. Second, as Andrew Light points out, ecological essentialism can share its metaphilosophical position with the pragmatist epistemology. While Anthony Weston pursues pluralism, admitting that the foundationalism might be one of the efficient approaches to nature, Eric Katz is also clearly attracted to the metaphilosophical element in Weston's argument that anyone who attempts to claim the 'inherent value' of non-human nature never possibly avoids a pitfall of anthropomorphism. Lastly, in a more comprehensive perspective, Dewey's pragmatism shows a philosophical complexity, what Larry A. Hickman calls 'post-postmodernism.' a dynamic interaction between modernism and postmodernism. Significantly enough, the environmental version of this complexity can procure a meeting ground between foundationalist ecology and the pragmatic view of nature.

Taepyeongso was introduced from China during the end of the Goryeo period and was used widely in Daechwita (military processional music), Pungmul-nori (farmers music), Buddhist music, royal ancestral rite music, and Sinawi, the instrumental accompaniment to shaman dances. Now, It has been popular as it is used for pop music and it is easy to learn. In this paper, Taepyeongso was analyzed for electronic Taepyeongso using physical modeling. We extracted resonance properties of Taepyeongso through the analysis of Taepyeongso sound. We analyzed the bell, the bore and the mouthpiece using FFT and LPC curve. As a result, the bell could be represented 2 pole filter and reflection filter between bore and bell.

Robert Frost's poetry has generally been considered fairly readable partly because of the simplicity or down-to-earth-ness of the messages that go along with the poet's projected public image and the 'traditional' forms he used. Against the grain of such general perception, this study reads some of the early poems of Robert Frost to re-characterize the beginning of the poet's career as a modernist attempt to challenge the dominant poetic conventions of the time: the genteel conventions. In reading the poems, this study focuses on frost's strategic method of using the speaker or persona regarding the delivery of meanings. Those readers who would like to find the immediate presence of Frost's voice in the poems, fail to distinguish the speaker and the poet, readily accepting the face value of what the speaker tries to convey: those messages which are in line with liberal individualism, like self-reliance, autonomous self, work ethics, etc. Frost's speakers, however, are rarely the mouthpiece of the poet himself. Rather, they are fictional characters who, while on the surface of the text appear to be hammering out a stable theme out of their everyday experience, under a heuristic scrutiny of the textual structure, turn out to be undermining the logic or the rationality of the theme, which can be identified as a modernist textual strategy that challenges the traditional conventions regarding the stability of meaning in a poetic text.

Young Tolstoy, when he was an already well-known writer, accomplished his first overseas travel in 1857, which gave him imaginable opportunities to compare his country's social strata with others such as serfdom, monarchical Russia and industrial and capital Europe. The present story is, indeed, the work which is influenced by those experiences by young Tolstoy during his first journey into Europe. Written in the form of booklet-like-small-piece, rather than an artistic work, the text presents the writer's severe criticism on the world of nature and civilization. Close to the nature itself, narod are those common people for Tolstoy, and they represent love, while the nature creates a necessity to love, hope and bottomless happiness of life. On the contrary, the civilized or civilization itself is considered artificial, willy, reasonal, and erotic congruity among people. For the writer, the most unsafe and ugly, seamy side of the westernized society is a lack of necessity to unify people to people. Though in its early embryonic stage, young Tolstoy's worldview is reflected in this work, especially his sharp tongue on the western people and their society is also detected when the write imposes his message under the mask of a gypsy singer. In addition, the narrator who seems an obvious Tolstoy's mouthpiece delivers his own ideas and impression on the western world, history, art, and literature. For this very reason, the present work contains numerous signs from which the reader is able to interpret, understand, and figure out what young Tolstoy imposes for his work.

Background : Several studies have suggested that impaired mucociliary clearance plays a role in the pathophysiology of bronchial asthma. Cough productive of mucoid sputum is common, and mucous plugs in the airways are frequently observed. These clinical features are in keeping with the histologic lesions of asthma, which involve primarily the epithelial and mucous-producing structures of the conducting airways. Some studies have shown that the mucociliary clearance is impaired in adult asthma, but it has not been studied in childhood asthma. The objectives of this study were to examine whether the mucociliary clearance is impaired in childhood asthma and to estimate the degree of impairment in comparison with that of immotile cilia syndrome. Method : Thirteen children with mild stable asthma and eight patients with immotile cilia syndrome completed this study. Ten healthy children were recruited as a normal control group. The whole-lung mucociliary clearance was measured by the radioaerosol technique. Aerosols, tin colloid particles tagged with the radionuclide technetium-99m($^{99m}Tc$), were generated by means of nebulizer, and inhaled via a mouthpiece. The retention of radioactivity was measured at 30, 60, 90 and 120 minutes by gamma camera, and mucociliary clearance was calculated as percent retention at each time. Results: 1) In each subject, the percent retention decreased variably with the lapse of time. 2) The percent retention of radionuclide decreased at each time in order of normal control, bronchial asthma and immotile cilia syndrome and the percent retention of immotile cilia syndrome was significantly higher than that of normal control at each time(p<0.05). 3) At two hours, the percent retention of bronchial asthma($65.0{\pm}1.8$(SE)%) was significantly higher than that of the normal control($54.4{\pm}3.5%$, p<0.05), and significantly lower than that of immotile cilia syndrome($73.3{\pm}1.4%$, p<0.01). 4) When the percent retention was analyzed according to $PC_{20}$ in the children with bronchial asthma, they had no relationship with each other. Conclusion: Mucociliary clearance in the children with bronchial asthma was significantly lower than normal control. This finding indicates that impaired mucociliary clearance operates in childhood asthma as well, and suggests that it may be one contributing factor in the pathogenesis of asthma. The degree of impairment, however, was not so severe as immotile cilia syndrome.

Purpose: The purpose of this study is to evaluate the effectiveness of oral positioning stent, the BinkieRT^TM in radiation treatment for head and neck cancer patients in terms of tongue positions reproducibility, tongue doses and material properties. Materials and Methods: 24 cases using BinkieRT^TM during radiation treatments were enrolled. The tongue was contoured on planning CT and CBCT images taken every 3 days during treatment, and then the DSC and center of tongue shift values were analyzed to evaluate the reproducibility of the tongue. The tongue dose was compared in terms of dose distribution when using BinkieRT^TM and different type of oral stents (mouthpiece, paraffin wax). Randomly selected respective 10 patients were measured tongue doses of initial treatment plan for nasal cavity and unilateral parotid cancer. Finally, In terms of material evaluation, HU and relative electron density were identified in RTPS. Results: As a result of DSC analysis, it was 0.8 ± 0.07, skewness -0.8, kurtosis 0.61, and 95% CI was 0.79~0.82. To analyze the deviation of the central tongue shift during the treatment period, a 95% confidence interval for shift in the LR, SI, and AP directions were indicated, and a one-sample t-test for 0, which is an ideal value in the deviation(n=144). As a result of the t-test, the mean and SD in the LR and SI directions were 0.01 ± 0.14 cm (p→.05), 0.03 ± 0.25 cm (p→.05), and -0.08 ± 0.25 cm (p ←.05) in the AP direction. In the case of unilateral parotid cancer patients, the Dmean to the tongue of patients using BinkieRT^TM was 16.92% ± 3.58% compared to the prescribed dose, and 23.99% ± 10.86% of patients with Paraffin Wax, indicating that the tongue dose was relatively lower when using BinkieRT^TM (p←.05). On the other hand, among nasal cavity cancer patients, the Dmean of tongue dose for patients who used BinkieRT^TM was 4.4% ± 5.6%, and for those who used mouthpiece, 5.9% ± 6.8%, but it was not statistically significant (p→.05). The relative electron density of Paraffin Wax, BinkieRT^TM and Putty is 0.94, 0.99, 1.26 and the mass density is 0.95, 0.99 and 1.32 (g/cc), Transmission Factor is 0.99, 0.98, 0.96 respectively. Conclusion: The result of the tongue DSC analysis over the treatment period was about 0.8 and Deviation of the center of tongue shifts were within 0.2 cm, the reproducibility was more likely excellent. In the case of unilateral head and neck cancer patients, it was found that the use of BinkieRT^TM rather than Paraffin Wax or Putty can reduce the unnecessary dose irradiated to the tongue. This study might be useful to understand of BinkieRT^TM's properties and advantages. And also it could be another considered option as oral stent to keep the reproducibility of tongue and reducing dose during head and neck radiation treatments.

In this paper, I examine the development of the second stage of Chicano muralism and compare it with the first stage of the Chicano Mural Movement that was born out of the Civil Rights Movement. I then discuss the different aspects of the first stage in relation to the birth of institutionalized public art and question how Chicano murals influenced public art and, conversely, how mainstream public art transformed some of the attitudes and practices of Chicano muralism. Chicano murals initially functioned as a political mouthpiece for Chicano's human rights and as a tool to recover the Chicano people's cultural pride and legacy. However, the murals gradually developed into public art projects supported by the city or federal governments, who regarded them as an economic way to effectively communicate with the community. In this process of institutionalization, muralists became increasingly concerned with aesthetic quality and began to work more systematically. For example, amateur artists or community participants who produced the earlier murals were transformed into mural experts. Chicano essentialism and the politically volatile themes used previously were phased out and the new murals began to incorporate diverse subjects and people, for example, native culture, Blacks, and women. This phenomenon reflected the changing emphasis on multicultural understanding. This kind of institutionalization did not always draw positive results. Inadequate funds were the primary concern over the actual subject and creation of the mural work. Artists reduced the strong political metaphors and aestheticized the mural forms. However, their work was productive as well: thorough research on wall conditions and painting techniques was conducted and new processes and designs were developed. This paper examines the murals created for the 1984 Los Angeles Olympic Games, Judy Baca's works, and the Balmy Alley Mural Environment project in San Francisco's Mission District. Works by Las Mujeres Muralistas in Mission District, in particular, show case colorful patterns and the Latin American indigenous culture, exploring new interpretations of old icons and design. They challenged the stereotypical depictions of females and presented alternative visual languages that revised the male-centered mural aesthetics and elaborated on the aesthetics of Rasquachismo.

The oral hygiene of patients admitted to the ICU (Intensive Care Unit) is very important. Critically ill patients are basically immunocompromised ones because of the high risk of infection by various pathogenic bacteria. The mouth is not only the primary site of infection, but also the site of systemic infections. The purpose of this study was to design a mouthpiece type vacuum oral cleaner for the oral care of seriously ill patients. A 3D CAD modeling and flow analysis model were established for a double structure type cleaner and standard tooth model, and their pressure and flow characteristics were analyzed. The pressure inside the oral cleaner was almost constant, but the velocity distribution showed a large difference between the inside and outside of the teeth. The velocity at the center region inside of the teeth was the highest, and the speed decreased as the distance from the center increased. In the analysis of the case where the suction tube was replaced by the drainage tube, the velocity at the center of the outer portion of the teeth was the highest. In order to increase the effectiveness of the oral cleaner, alternating between suction and drainage is proposed, and a design complement to increase the speed of the molar region is required.
