Problems of Expressiveness in Geoaesthetics  [PDF]
Kwang Myun Kim
Open Journal of Philosophy (OJPP) , 2014, DOI: 10.4236/ojpp.2014.44061
Abstract: Facing in the prospect of geo-environmental activities like volcanic explosions, earthquakes, floods, landslides, subsidence issues, tsunamis, etc., we have to reconsider a sustainable harmony between human beings and nature. Approaching the reality of the changing patterns of the earth’s surface and geological processes geoaesthetically will be helpful in establishing a more desirable relationship between human beings and nature. In this paper the author attempts to consider the meaning of expressiveness in relation to geoaesthetics, and further the author intends to reveal expressiveness through various phenomena of the earth. Expressiveness can evoke emotion as one experiences the aesthetic object. Empathy plays a role in drawing expression from expressiveness. One can find geoaesthetic expression through looking deeply into the expressiveness the earth presents. Earth itself is inanimate, but owing to its plentiful expressiveness it can restore the organic, animate world.

Abstract: Background Natural cytotoxicity, mediated by natural killer (NK) cells plays an important role in the inhibition and elimination of malignant tumor cells. To investigate the immunoregulatory role of NK cells and their potential as diagnostic markers, NK cell activity (NKA) was analyzed in prostate cancer (PCa) patients with particular focus on NK cell subset distribution. Methods Prospective data of NKA and NK cell subset distribution patterns were measured from 51 patients initially diagnosed with PCa and 54 healthy controls. NKA was represented by IFN-γ levels after stimulation of the peripheral blood with Promoca?. To determine the distribution of NK cell subsets, PBMCs were stained with fluorochrome-conjugated monoclonal antibodies. Then, CD16+CD56dim and CD16?CD56bright cells gated on CD56+CD3? cells were analyzed using a flow-cytometer. Results NKA and the proportion of CD56bright cells were significantly lower in PCa patients compared to controls (430.9 pg/ml vs. 975.2 pg/ml and 2.3% vs. 3.8%, respectively; p<0.001). Both tended to gradually decrease according to cancer stage progression (p for trend = 0.001). A significantly higher CD56dim-to-CD56bright cell ratio was observed in PCa patients (41.8 vs. 30.3; p<0.001) along with a gradual increase according to cancer stage progression (p for trend = 0.001), implying a significant reduction of CD56bright cells in relation to the alteration of CD56dim cells. The sensitivity and the specificity of NKA regarding PCa detection were 72% and 74%, respectively (best cut-off value at 530.9 pg/ml, AUC = 0.786). Conclusions Reduction of CD56bright cells may precede NK cell dysfunction, leading to impaired cytotoxicity against PCa cells. These observations may explain one of the mechanisms behind NK cell dysfunction observed in PCa microenvironment and lend support to the development of future cancer immunotherapeutic strategies.
The Aesthetic Turn in Everyday Life in Korea  [PDF]
Kwang Myung Kim
Open Journal of Philosophy (OJPP) , 2013, DOI: 10.4236/ojpp.2013.33054
Abstract: We are living in the transitional age from the rational, analytical, and scientific to the cultural, sensitive, and aesthetic. The aesthetics of everyday life lies at the center of this age. There is no boundary between art and life in contemporary art. Almost all the contents and objects of everyday life became a work of art in the condition of searching for the aesthetic. Since aesthetic theory was shifted from the artist-centered or a work of art-centered to the audience, spectator or beholder-centered, art and everyday life were more closely related to each other. So aesthetic attention or attitude is not specific to art, but pervasive broadly in everyday life. We can embrace the aesthetic concerns in everything we make and use every day. In the long tradition of Korean art, it can be seen that aesthetic consciousness is steeped in day-to-day life as well as the arts. I want to consider the problems of everydayness, Korean aesthetic consciousness in daily life, and contemplation in the aesthetic consciousness. Korean art was characterized by its “lack of refinement” and “nonchalance”. The characteristics of Korean art as the qualities of “technique without technique”, “Planning without plan”, “asymmetrical symmetry” have dominated the everyday consciousness of Korean people as well as Korean art. The extension of aesthetic emotion through experimentation shows us the change of aesthetic consciousness as a new possibility of interpretation. We stand in an urgent situation of the need for a new theory of art. It will be related to the future of aesthetics. For this reason, I think we have to consider the meaning of the aesthetic turn in everyday life.
Problems and Prospects of Geoaesthetics  [PDF]
Kwang Myung Kim
Open Journal of Philosophy (OJPP) , 2015, DOI: 10.4236/ojpp.2015.51001
Abstract: Geoaesthetics is the project of making aesthetic sense of nature through geological phenomena. The aesthetic appreciation of nature has recently become urgent because of the serious influence of the natural environment on human beings. The author’s geoaesthetical research is categorized into three problems: art in geology or geology in the arts as the close relationship between art and geology, geological cognition of nature and natural cognition in environmental aesthetics, and the geoaesthetical approach through works of art. Geologic forces and processes have become significant materials for aesthetic sensations. Based on the geoaesthetic perspective, the author explores the ultimate purpose of art as a return to natural order. It seems partly to be related to the ontological problem of art. Here we can feel earthly dynamics, universal calmness, and the contemplative atmosphere simultaneously.
Double tailgut cysts (presacral and precoccygeal hamartomas) with CA 19-9 elevation  [PDF]

Case Reports in Clinical Medicine (CRCM) , 2013, DOI: 10.4236/crcm.2013.21002
Abstract:

Tailgut cyst, also called retrorectal hamartoma, is a rare congenital lesion and is usually located anterior to the sacrum and posterior to the rectum. We report a case of double tailgut cyst (presacral and precoccygeal hamartoma). A 62-year- old female visited the hospital complaining of anal pain and pressure in the perianal area for one month. Digital rectal examination revealed a round mass with hard consistency in the lateral and posterior part of rectum 5 cm from the anal verge. Pelvic magnetic resonance imaging showed two cystic and solid presacral masses (lateral and posterior part of rectum) compressing the rectum. The patient underwent surgical resection for pathologic diagnosis. At operation, two masses were located in the left presacral space without invasion to adjacent organs and soft tissue. Pathologic examination revealed double tailgut cysts without malignant transformation. A differential diagnosis of perirectal cystic hamartoma includes epidermal cysts, cystic teratomas, dermoid cysts, anal gland cysts, sarcoma and rectal duplications. Regional inflammatory process frequently complicates this lesion and perirectal fistula can develop. Tailgut cyst also has a malignancy potential, with development of adenocarcinomas. To establish a definite diagnosis and prevent complication, complete surgical resection is recommended.

Anterograde jejunojejunal intussusception resulted in acute efferent loop syndrome after subtotal gastrectomy
Jung Myun Kwak, Jin Kim, Sung Ock Suh
World Journal of Gastroenterology , 2010,
Abstract: Postoperative intussusception is an unusual clinical entity in adults, and is rarely encountered as a complication following gastric surgery. The most common type after gastric surgery is retrograde jejunogastric intussusception, and jejunojejunal intussusception has been rarely reported. We report a case of anterograde jejunojejunal intussusception after radical subtotal gastrectomy with Billroth II anastomosis in a 38-year-old Korean woman with early gastric cancer, and include a review of the literature on this unusual complication.

Mathematics , 2004, DOI: 10.1214/009053604000000175
Abstract: Finite sample properties of multiple imputation estimators under the linear regression model are studied. The exact bias of the multiple imputation variance estimator is presented. A method of reducing the bias is presented and simulation is used to make comparisons. We also show that the suggested method can be used for a general class of linear estimators.
Isolation Enhancement between Indoor Repeater Antennas with Chip Resistor Embedded FSS
Jae-Yeong Lee,Byeongkwan Kim,Myun-Joo Park,Byungje Lee
International Journal of Antennas and Propagation , 2012, DOI: 10.1155/2012/307616
Abstract: The isolation enhancement between the donor antenna and the service antenna for indoor repeater systems is presented by using a frequency-selective surface (FSS). A unit cell of the proposed FSS consists of a quarter-wavelength resonator, a chip resistor, an FR4 substrate, and a ground plane. Applying the unit cells of the proposed FSS embedded a chip resistor on the side walls of each reflector for indoor WCDMA repeater antennas and aligning them along with the cross-polarization of each antenna, the isolation is improved by about 13 dB at the WCDMA band.
Metronidazole neurotoxicity: Sequential neuroaxis involvement
Park Kyung-Il,Chung Jae-Myun,Kim Ji-Young
Neurology India , 2011,
Abstract: Neurological manifestation of metronidazole toxicity include neuropathy and encephalopathy. We report a 67-year-old man with progressive painful paresthesias involving all the four limbs of 3 weeks′ duration before admission. He had been treated with metronidazole and cephalosporin for 10 weeks for a hepatic abscess. Five weeks after the symptom onset, he complained of dysarthria and limb ataxia. Magnetic resonance imaging revealed signal abnormalities in the splenium of the corpus callosum and bilateral dentate nuclei. A few hours after brain imaging, the patient exhibited excessive diaphoresis and fluctuation in blood pressure, which resolved within several hours after discontinuation of metronidazole. Whereas his speech returned to near normal within approximately 1 week, a burning sensation was not completely relieved, even 6 months after discharge.
On the Security of Lee, Kim, Kim, & Oh Key Agreement Protocol
Kim-Kwang Raymond Choo
International Journal of Network Security , 2006,
Abstract: In ICCSA 2005, Lee, Kim, Kim, & Oh proposed a new (two-party) ID-based key agreement protocol, which they claimed to provide known key security resilience, forward secrecy, key compromise resilience, unknown key share resilience, and key control, however, without providing any security proofs. In this work, we demonstrate that their claims of known key security resilience and key control are flawed by revealing previously unpublished flaw in the two-party ID-based key agreement protocol. We may speculate that such (trivial) errors could have been found by protocol designers if proofs of security were to be constructed, and hope this work will encourage future protocol designers to provide proofs of security. We conclude with a countermeasure due to Choo, Boyd, & Hitchcock (2005).
