Preclinical Efficacy Examination on Healing Practices and Experiences of Users for Pillows and Mattresses of Loess Ball Bio-products

AbstractIn Korea, loess has been known as a healthy material traditionally, and in everyday life it has been used in various fields. Korean loess ball has unique electrical and magnetic properties indispensable to survival of human being such as living-light of far-infrared radiation which has been applied to various bio-products. However, the medical investigation of its efficacy for such bio-products has remained insufficient. The purpose of this paper is to check not only chemico-physical data but also medical data on the medical efficacy for the various healing practices and effects shown in users of these products. The Korean loess ball was manufactured by several powder processes at low temperature such as aging, mild grinding, separation, granulation, and drying. The healing effects for the bio-products of the loess ball were confirmed based on the statistical analysis of user's experience for healing practices evaluated by Somatoscope microscope observations of the movement of red blood cells in living blood, the infrared thermography diagnostic equipment, the comparison of Digital Infrared Thermal Imaging, DITI photos, the survey of literature review on the loess healing including the Donguibogam edited by Jun Heo. In conclusion, when slept on loess ball bio-products such as pillows or mattresses, the congestion of red cells in the blood of the human body is relieved and the blood circulation in blood vessel is smoothly improved. The wave resonance actions of far-infrared rays radiated from the loess ball bio-products enforce the receptor and intracellular enzymes to act the interaction of a variety of pain and stress and to bring a healthy condition. Further study for clarifying medical healing mechanisms of bio-products through the clinical test in both the oriental and western hospital is requested and the upgrade of present bio-products becomes obvious

Oscillation death in coupled counter-rotating identical nonlinear oscillators

We study oscillatory and oscillation suppressed phases in coupled counter-rotating nonlinear oscillators. We demonstrate the existence of limit cycle, amplitude death, and oscillation death, and also clarify the Hopf, pitchfork, and infinite period bifurcations between them. Especially, the oscillation death is a new type of oscillation suppressions of which the inhomogeneous steady states are neutrally stable. We discuss the robust neutral stability of the oscillation death in non-conservative systems via the anti-PT-symmetric phase transitions at exceptional points in terms of non-Hermitian systems.Comment: 7 pages, 4 figure

Amplitude death in a ring of nonidentical nonlinear oscillators with unidirectional coupling

We study the collective behaviors in a ring of coupled nonidentical nonlinear oscillators with unidirectional coupling, of which natural frequencies are distributed in a random way. We find the amplitude death phenomena in the case of unidirectional couplings and discuss the differences between the cases of bidirectional and unidirectional couplings. There are three main differences; there exists neither partial amplitude death nor local clustering behavior but oblique line structure which represents directional signal flow on the spatio-temporal patterns in the unidirectional coupling case. The unidirectional coupling has the advantage of easily obtaining global amplitude death in a ring of coupled oscillators with randomly distributed natural frequency. Finally, we explain the results using the eigenvalue analysis of Jacobian matrix at the origin and also discuss the transition of dynamical behavior coming from connection structure as coupling strength increases.Comment: 14 pages, 11 figure

The Carlitz shtuka

Recently we have used the Carlitz exponential map to define a finitely generated submodule of the Carlitz module having the right properties to be a function field analogue of the group of units in a number field. Similarly, we constructed a finite module analogous to the class group of a number field. In this short note more algebraic constructions of these "unit" and "class" modules are given and they are related to Ext modules in the category of shtukas.Comment: 9 page

Time Delay Effect on the Love Dynamical Model

We investigate the effect of time delay on the dynamical model of love. The local stability analysis proves that the time delay on the return function can cause a Hopf bifurcation and a cyclic love dynamics. The condition for the occurrence of the Hopf bifurcation is also clarified. Through a numerical bifurcation analysis, we confirm the theoretical predictions on the Hopf bifurcation and obtain a universal bifurcation structure consisting of a supercritical Hopf bifurcation and a cascade of period-doubling bifurcations, i.e., a period doubling route to chaos.Comment: To appear in Journal of Korean Physical Societ

Landform recognition in granite mountains in East Asia (Seoraksan, Republic of Korea, and Huangshan and Sanqingshan

Applied research in geomorphology includes landform analysis and evaluation from a specific perspective of scientific significance and global relevance. In this paper, landform diversity of Seoraksan, Republic of Korea, a UNESCO World Heritage candidate, is compared with geomorphic characteristics of two World Heritage properties in China, Huangshan and Sanqingshan. Seoraksan represents an almost complete mountain geomorphic system of considerable contemporary dynamics, with outstanding scenery and spectacular landforms such as domes, fins, bedrock channels, waterfalls, and inherited block fields. It is argued that Seoraksan contains outstanding scientific and aesthetic values, not present at the Chinese properties, offering scope for successful nomination
