  • In view of the planned NASA's and ESA's Solar Probe Plus and Solar Orbiter missions, respectively, to probe the inner heliosphere and the Sun's corona, it is timely to investigate outstanding problems associated with the solar wind. Among them is the temperature anisotropy problem. As the solar wind expands into the interplanetary space, the density and magnetic field decreases radially, thus leading to temperature anisotropy ($T_{\parallel}{\gg}T_{\perp}$). However, the measured temperature anisotropy can at times be characterized by $T_{\perp}$ > $T_{\parallel}$, while at other times the measured $T_{\parallel}/T_{\perp}$ is much milder than predicted by adiabatic theory. Physical reasons remain poorly understood. This notwithstanding, it is known from plasma physics that for $T_{\perp}$ > $T_{\parallel}$ electromagnetic ion-cyclotron (EMIC) and mirror instabilities are excited, while for $T_{\parallel}$ > $T_{\perp}$, fire-hose instability is excited. By constructing the threshold conditions for various instabilities, one may construct a closure relation that may be useful for modeling the solar wind. In the present paper we discuss theoretical construction of the anisotropy-beta relation by means of quasi-linear theories of these instabilities. The present work complements previous efforts on the basis of linear theory, hybrid simulations, and empirical fits of observations.

  • In this paper we study the theory of knotoids and braidoids and the theory of pseudo knotoids and pseudo braidoids on the torus T. In particular, we introduce the notion of mixed knotoids in S2, that generalizes the notion of mixed links in S3, and we present an isotopy theorem for mixed knotoids. We then generalize the Kauffman bracket polynomial, <; >, for mixed knotoids and we present a state sum formula for <; >. We also introduce the notion of mixed pseudo knotoids, that is, multi-knotoids on two components with some missing crossing information. More precisely, we present an isotopy theorem for mixed pseudo knotoids and we extend the Kauffman bracket polynomial for pseudo mixed knotoids. Finally, we introduce the theories of mixed braidoids and mixed pseudo braidoids as counterpart theories of mixed knotoids and mixed pseudo knotoids, respectively. With the use of the L-moves, that we also introduce here for mixed braidoid equivalence, we formulate and prove the analogue of the Alexander and the Markov theorems for mixed knotoids. We also formulate and prove the analogue of the Alexander theorem for mixed pseudo knotoids.

  • The need for designing and implementing integrated policy was further emphasized in tandem with the increase in interest concerning policy coordination and interactions. An active discussion is taking place in the field of innovation policy concerning "integrated innovation policy," which considers innovation along with financial, regional development, social, and environmental policies together in a holistic manner. In Korea since the beginning of the 2000s, there were many attempts at implementing integrated innovation policy through the restructuring of the overall S&T administration system. For the purposes of taking an integrated approach to S&T policies as well as to S&T-related human resources, industrial, and regional development policies, the Roh Administration (February 2003~February 2008) elevated the S&T Minister to the level of Deputy Prime Minister as well as launching the Office of Science, Technology, and Innovation (OSTI) (October 2004 ~ February 2008) under the Ministry of Science and Technology. This study investigates the policy coordination activities of the OSTI from the perspective of policy integration. It deals with the background of the OSTI, its roles and responsibilities, the coordination process, and its achievements and limitations while discussing the important implications for developing effective policy measures with the hope of contributing to the development of theories of integrated innovation policy.

  • The theory-the doctrine of Confucius and Mencius was an objective existance in Chinese dietary culture history, but it was ignored in the last two thousand years. In addition, some people misunderstood Confucius' and Mencius' thoughts and statements. This paper believes that the doctrine of Confucius and Mencius is Confucius' and Mencius' diet opinions, thoughts, theories and basic style in their diet experiences. Confucius' diet experience and Mencius' diet experience were alike, and Mencius' experience carried on Confuius' and theirs were the same in some sections. They all stay their diet standard to their stomach and don't persue good meal. They all thought resolving people's diet was important for a country and for the politic problems. Mencius succeeded Confucius' diet thoughts and put them to the theories-diet principle, diet standard, and diet morality. This paper deeply discusses theory, developing history condition and the affection and position in Chinese diet history of the doctrine of Confucius and Mencius.

  • In this paper, a higher order shear deformation beam theory is developed for static and free vibration analysis of functionally graded beams. The theory account for higher-order variation of transverse shear strain through the depth of the beam and satisfies the zero traction boundary conditions on the surfaces of the beam without using shear correction factors. The material properties of the functionally graded beam are assumed to vary according to power law distribution of the volume fraction of the constituents. Based on the present higher-order shear deformation beam theory, the equations of motion are derived from Hamilton's principle. Navier type solution method was used to obtain frequencies. Different higher order shear deformation theories and classical beam theories were used in the analysis. A static and free vibration frequency is given for different material properties. The accuracy of the present solutions is verified by comparing the obtained results with the existing solutions.

  • The decomposition reaction mechanism of $CH_3CF_2O$ radical formed from hydroflurocarbon, $CH_3CHF_2$ (HFC-152a) in the atmosphere has been investigated using ab-initio quantum mechanical methods. The geometries of the reactant, products and transition states involved in the decomposition pathways have been optimized and characterized at DFT-B3LYP and MP2 levels of theories using 6-311++G(d,p) basis set. Calculations have been carried out to observe the effect of basis sets on the optimized geometries of species involved. Single point energy calculations have been performed at QCISD(T) and CCSD(T) level of theories. Out of the two prominent decomposition channels considered viz., C-C bond scission and F-elimination, C-C bond scission is found to be the dominant path involving a barrier height of 12.3 kcal/mol whereas the F-elimination path involves that of a 28.0 kcal/mol. Using transition-state theory, rate constant for the most dominant decomposition pathway viz., C-C bond scission is calculated at 298 K and found to be 1.3 ${\times}$ 10$^4s{-1}$. Transition states are searched on the potential energy surfaces involving both decomposition channels and each of the transition states are characterized. The existence of transition states on the corresponding potential energy surface are ascertained by performing Intrinsic Reaction Coordinate (IRC) calculation.

  • Buin-daejeon-yangbang is one of the special book on the traditional eastern medicine(T.E.M) Ob&Gy in Song dynasty. It remains very important book of the department of the Ob&Gy in today's T.E.M. There are a good deal of the useful theories and prescriptions about clinical Ob&Gy in it. Chen-zi-ming(陳子明) was a very famous Ob&Gy doctor and professor on T.E.M who came from Lincuan Jingxi(江西 臨川) province China in the South-Song dynasty. He was born in AD 1190, was died in AD 1270. Buin-daejeon-yangbang was written by him in AD 1237 and remained several kinds of edition now. It takes form total 8 volumes, 24 chapters. There are more than 260 medical references and 1500 prescriptions in it. And the formation of the book which the arrangement of theories and prescriptions is to keep in order. But it has some unreasonable and superstitious contents too. It performed as a bridge which link the results of pre-Song dynasty about clinical T.E.M Ob&Gy and after-Song dynasty about that. So it is a grandfather of a book for about clinical T.E.M Ob&Gy as following books like Gyoju-Buin-daejeon-yangbang, Yeougwa-Jeungchi-Junsung and Jeieum-Gangmock.

  • The most distintive features on the Thinking Structure of the Views of the Nature and the Theories of the Medicine of the ancient Chinese are a Comprehensions to the System of the Nature which reveals in the Natural Phenomena. Nothing doesn't changed in the Nature and man also. These Changes are inevitable to the man. So it isn't easy to grasp the Essence of the Natural Phenomena which always be changed. I-Ching (易經, Book of Changes), Chung-Yung (中庸) and many other books are that has a theories about the Changes, the ancients could recognized the unchangeable constancy from the ever changeable Natural Phenomena. The unchangeable constancy on the Oriental thinking means as same as an 'Idea' on the Western thinking. These process made them shape up the Views of the Nature and the Medical theories. And Chi (氣), Yin-Yang (陰陽) and Wu-Hsing (五行) are the most important concepts of their views and theories. In the concepts of Chi as an epistemological meaning; the Nature and the Han can be appreciated as a one System, because his being is within the Changes of the Nature and should be in accord with those Changes. He was going to believe that all beings are exist as an existential rules of himself. So Chi can be thougt as an epistemological system to all beings' existence. Thinking of Yin-Yang as a existential meaning; all beings are exist having a contrary and a complementary to each other. Birth and Death, Be ginning and Finishing in a series of the process occurs in all beings are the two sides of their existential and intrinsic tendencies. That can be condensed to the Yin-Yang concepts. In the consideration of Wu-Hsing;all beings are observed and explained more deliberatively by it's own rules. By the way the concepts of Chi, Yin-Yang and Wu-Hsing which derived from the processes of the recognition to the Changes of the Nature are practiced actually by the thoughts of Harmony. And it is represented by the accordance to the Time of the Natural Changes, that is, Shiling (時令). It means a adjustments to the Time and Changes of the Nature. The health of all beings that is an aim of the Medicine can be maintained by their practical thoughts or the concepts of Shiling.
