  • The very definitions of posture and balance have changed, as has our understanding of the underlying neural mechanisms, In rehabilitation science, there awe at least two different conceptual theories to describe the neural control of posture and balance : the reflex/hierarchical theory and system theory. A reflex/hierarchical theory suggests the posture and balance result from hierarchically organized reflex responses triggered by independent sensory systems. The systems approach suggests that action emerges from an interaction of the individual with the task and environment. That is to say, the systems approach implies that the ability to control our body's position in space emerges from a complex interaction of musculoskeletal and neural systems, collectively referred to as the postural control system. The specific organization of postural systems determined both by the functional task and the environment in which it is being performed, The postural control system is divided into three basic functional components for assessment : 1) musculoskeletal components, 2) motor coordination components, and 3) sensory organization components. It is proposed that a systemic functional understanding of human balance is critical to effective programs for balance rehabilitation. Thus, this article briefly reviews the basic functional components to consider in designing treatment plan and for the benefit of the balance assessment.

  • As above, it described Dr.Tanaka's Spiral Balance Theory and studied the theoretical background and the special meridian circulation system, diagnostics and treatments. Though the considered the rule of the tenseness of the body as muscle movement theory, it corresponds with tradtional meridians theory in oriental medicine. If we study and develop the traditional meridians circulaition system more, we can expect clinical development applying to any theories in the field of oriential medicine such as acupuncture therapy, moxa therapy and chiropractc therapy. etc, as well as tapaing therapy, electronic stimulation therapy and exercising therapy.

  • This study examines the distribution of power in Northeast Asia based on the balance of power theory, a representative theory of realism, assuming military capabilities as the core power of states. The results of previous studies on the balance of power and military forces are reviewed and used to analyze changes in the strength of the US, China, Russia, Japan, South Korea, and North Korea through 2020 to predict the security environment in 2030. In the balance of power theory, if the balance of power between a nation or a group of powers collapses, the possibility of war is high, and to survive in the international community with high uncertainty and distrust, the theory predicts that states must increase their powers in a self-help world and strengthen cooperation and alliance. Countries in Northeast Asia are also continuing to strengthen their military capabilities, and countries neighboring China are paying keen attention and remaining vigilant due to the rapid changes in the international security environment after the rapid rise of China. To mark the future 100th anniversary of the Chinese armed forces in the 2030s, China aims to realize 'defense and military modernization' and build a 'world-class military force' by the nation's 100th anniversary in the 2050s. The US is busy checking China's rise by strengthening international cooperation and alliances. The security environment and power dynamics in Northeast Asia are slowly changing as the US and China continue to compete for global hegemony. The changes and implications of the distribution of power in Northeast Asia after 2030 are examined based on the balance of power theory.

  • This study attempted to analyze in detail the actions used by children and to uncover the theories used by those children whilst engaged in solving balance tasks. Sixty children, aged between 3 to 6 from "H" child care center located in Seoul were selected as the subjects. The children were asked to balance 8 different blocks by putting them on a bar one by one. Two of the 8 blocks were balanced by the center of the length of the block, two were unbalanced by the center of the length because another block is glued on the side of the bottom block, three blocks were unbalanced due to the insertion of a piece of metal in the side of the blocks, and one was completely unbalanced because it consisted of three layers of blocks glued obliquely. Fifteen actions undertaken by the children in solving the tasks were analyzed and divided into 6 categories : place, turning, push, press, support, and others. Children used three theories which were 'no theories', 'length centered theory' and 'considered both length and weight theory' whilst engaged in balance tasks.

  • In this study, the prognostic model for the prediction of the road surface temperature is developed using the surface energy balance theory. This model not only has a detailed micro meteorological physical attribute but also is able to accurately represent each surface energy budget. To verify the performance, the developed model output was compared with the German Weather Service (DWD)'s Energy Balance Model (EBM) output, which is based on the energy budget balance theory, and the observations. The simulated results by using both models are very similar to each other and are compatible with the observed data.

  • This study began to confirm or review the balance of power theory by applying scientific methods through experiential cases. Though there are several kinds of national power, this study supposes military power as a crucial power when it comes to war and peace. This research covered balance and imbalance through comparing relative military power between nations or nations' group. Comparison of relative military power can be achieved by statistically processing the values of which has been converted into the standard variables in same domain, then calculating the values of nation's power which has been synthesized different experiential factors. In addition, the criteria of experiential experiment is highly dedicated to European countries, USA, Japan prior to 1st and 2nd World War, as well as USA, Soviet Union and North East Asia during Cold War era. In addition, the balance of power theory has been redefined to review the action of the state upon the changes of power as mentioned in the theory. To begin with, the redefined theory states that relative level of military power between nations defines the consistency of peace and balance of power. If military power is enough to be on the range of level required to keep the power in equilibrium, peace and balance can be achieved. The opposite would unbalance the military power, causing conflicts. While the relative military level between nations change, nations seek to establish 'nations group' via military cooperation such as alliance, which also shift relative military power between nations group as well. Thus, in order to achieve balance of power, a nation seeks to strengthen its military power(self-help), while pursuing military cooperation(or alliance). This changes relative military power between nations group also. In other words, if there exists balance of power between nations, there is balance of power between nations group as well. In this theory, WWI and II broke out due to the imbalance of military force between nations and nations group, and reviewed that due to the balance of military force during the Cold War, peace was maintained. WWI was resulted from imbalance of military cooperation between two powerful states group and WWII was occurred because of the imbalance among the states. Peace was maintained from cooperation of military power and balance among the states during the Cold War. Imbalance among continental states is more threatening than maritime states and balance of power made by army force and naval force also is feasible. Also the outcomes of two variables are found military power balanced ratio of military power for balance is 67% when variable ratio of balance is 100% and standard value for balance is 0.86. Military power exists in a form of range. The range is what unstabilized the international system causing nations to supplement their military powers. These results made possible the calculation and comparison between state's military power. How balance of power inflicted war and peace has been studied through scientific reviews. Military conflict is highly possible upon already unbalanced military powers of North East Asian countries, if the US draws its power back to America. China and Japan are constantly building up their military force. On the other hand, Korean military force is inferior so in accordance to change of international situation state's survival could be threatened and it is difficult to achieve drastic increase in military force like Germany did. Especially constructing naval force demands lots of time; however but has benefit that naval force can overcome imbalance between continental states and maritime states.

  • Objectives : The purpose of this paper is to examine Zhang Zihe's reinforcement method based on the theory of keeping balance(以平爲期). Methods : Based on his arguments in the Rumenshiqin and formula compositions, Zhang Zihe's reinforcement method was examined. Results & Conclusions : 1. Despite preconceptions that Zhang Zihe must have been critical of reinforcement methods due to his alliance to the offensive purgative group, in reality his criticism was not aimed at reinforcement methods entirely, but rather at warming and tonifying. 2. Zhang Zihe's criticism of warming and tonifying was based on his research of the Neijing, in which he realized the pathogenic effects of fire-heat and the side effects of warming and tonifying in clinical practice. This is a common conception among the Four Great Doctors of the Jin-Yuan period. 3. Zhang Zihe focused on eliminating pathogenic qi so that the body's qi would circulate smoothly to slowly restore the source qi. The theory of keeping balance was emphasized to achieve this goal. 4. Based on the theory of keeping balance, Zhang Zihe used various medicinals with different properties and flavors to allow for the medicinals in each of the sovereign, minister, assistant and courier positions to co-operate with each other, while using food reinforcement to restore the source qi.

  • This paper investigates the source of bilateral trade imbalance at industry level. We build a simple model based on gravity theory and derive the prediction that the bilateral trade balance in an industry is increasing in the difference between trading partners in the output share of the industry. We test this prediction and find that the difference in industry share is highly significant in predicting both the sign and the magnitude of trade balance at industry level. We also find that FTAs tend to enlarge trade imbalance at industry level. However, the overall predictive power of the model is rather limited, suggesting that factors other than production specialization are important in determining trade balance at industry level. Another finding of the paper is that the influence of the difference in industry share on trade balance increases as we move to industries that produce more homogeneous products. This finding calls into question monopolistic competition as the main driver of gravity in international trade.

  • Objectives : Functional Cerebrospinal Therapy (FCST) is a new physiologic therapeutics developed in Korea as a meridian yinyang balance approach. The theory of yinyang balance has been at the core of health enhancement approach of meridian and acupuncture medicine ever since its start. Methods : Introductory overview of FCST is presented in relation with meridian yinynag balance theory. Results : As the temporomandibular joint (TMJ) and related tissues have direct interconnection with brainstem proprioceptive or motor systems and the face is where all the meridians converge, FCST applies a fine adjustment of the posture of TMJ as a treatment tool for neurologic conditions or meridian imbalances. Conclusions : Highly sophisticated diagnostic and therapeutic techniques to adjust various subset aspects of yinyang balance are developed within FCST, which is supposed to be one of major contributions to natural healing.

  • This study focuses on the limit cycle oscillations (LCOs) of cantilever swept-back wings containing a cubic nonlinearity in an incompressible flow. The governing aeroelastic equations of two degrees-of-freedom swept wings are derived through applying the strip theory and unsteady aerodynamics. In order to apply strip theory, mode shapes of the cantilever beam are used. The harmonic balance method is used to calculate the frequencies of LCOs. Linear flutter analysis is conducted for several values of sweep angles to obtain the flutter boundaries.
