The architectural design process is consisted of the phase of programming and the phase of the design. The contemporary architectural scheme, as a datascape, a rhizome structure and a diagram, is based on the concept of modern physics. And it is applied on the phase of design by synthesizing data. Like this, the design of the architectural field is accomplished in the phase of design. For design of the architectural field, the characteristics of the architectural field is considered as the viewpoint of design in the procedure. First, according to the area which is defined by relations of environments, around architectures and so on, the net system of relations is designed as area. Second, design the linkage between building and space, building and building, space and space, according to the correspondence each other. Third, design the method or form of connecting building and space to one as a building and a space are no longer divided but are understood by one. As a result, for the design of architectural field, it is necessary to define the criteria by the characteristics of architectural field and the architectural field is designed by process.

The observation of the new biotite isograd (chlorite + chloritoid = andalusite + biotite) in the Mungyong coal field requires the modification of Harte and Hudson's (1979) metapelite grid which eliminates the stability field of staurolite + cordierite assemblages. The newly proposed metapelite grid by Ahn and Nakamura (2000) can define more properly the isograd reaction observed from nature. We discuss first topological interrelations between synthetic system (FASHO-, KFASHO-, KFMASH system) on an isobaric section at 2kbar, where phase relations are well constrained. The following discussion is concentrated on the topological relations between stable reactions. At the last, we discuss the petrogenetic significance of the Ahn's petrogenetic grid compared with theoretically computed grids. Ahn's petrogenetic grid is consistent with synthetic and natural system, and is one of the excellent example of KFMASH approximation in metapelite.

To explanin allopatric distribution of Carpinus cordata and C. laxiflora in the field the effect of soil flooding on photosynthesis and water relations was tested with field grown saplings. Under the flooding condition stomatal conductance of C. laxiflora decreased markedly from day two after flooding treatment and remanined low throughout the experiment. In contrast, flooding had no effect on stomatal conductance of C. cordata throughout the exper iment. The rate of photosynthesis of C. laxiflora was significantly suppressed under flooding conditions, whereas that of C. cordata was not affected in the flooded condition. On day seven after flooding treatment xylem pressure potential of C. laxiflora significantly decreased. Flooding, however, did not have any effect on the xylem pressure potential of C. cordata throughout the experiment. From these findings it is concluded that there is a difference in resistance to flooding between C. cordata and C. laxiflora and that one of the the factors responsible for allopatric distribution in the two species is flooding.

The manifold $^{\ast}g-ESX_n$ is a generalized n-dimensional Riemannian manifold on which the differential geometric structure is imposed by the unified field tensor $^{\ast}g^{{\lambda}{\nu}}$ through the ES-connection which is both Einstein and semi-symmetric. The purpose of the present paper is to derive a new set of powerful recurrence relations and to prove a necessary and sufficient condition for a unique Einstein's connection to exist in 5-dimensional $^{\ast}g-ESX_5$ and to display a surveyable tnesorial representation of 5-dimensional Einstein's connection in terms of the unified field tensor, employing the powerful recurrence relations in the second class.

Purpose: The definition of healing and treatment is different between the East and the West. I suppose that the different definitions of them affect the notion of healing environment in two cultural area. Therefore the aim of this study is to consider the different perspective in healing environment between the East and the West. Methods: Relevant literature review around domestic and foreign reference in fields of medicine and architecture has been conducted to consider the purpose. Results: First, the perspective that the cause of disease stems from inside of body approaches the body from standpoint of healing for recovery. Healing is the way to conquer imbalance by entering into a connection with nature around body. The concept of healing could analyze that it come from relevant perspective. Second, the healing environment in the East is the place where the flow of Qi between, human and human, and, human and environment, keep a balance. The notion of healing environment in the East is the filed of relations. In the West, the notion of healing environment is the place where arouse fine emotions through sensory stimulations. Implications: Recently the studies of healing environment focus on deducing sensory stimulation factors scientifically in the perspective of the West. But the healing environment couldn't be possible without the notion of place of relations. In the future, the notion of healing environment as the field of relations in the East has to be concerned.

The purpose of this study was to explore the patterns of investment on children, analyze the differences in academic performance and social relations by the patterns of investment on children, and variables that influence academic performance and the social relations of children. To achieve such research objectives, the raw data from the 2012 Korean Child and Youth Panel investigation were used for the research. The analytical subjects of this research were the parents and the third-grade students of a middle school and the analytical methods used were: frequency, percentage, average, standard deviation, Chi-squared test, ANOVA, Duncan's Multiple Range test, K-mean cluster, and multiple regression analysis depending on the research purpose. The results of the research are as follows. Firstly, as a result formalizing investment pattern on children, there were five patterns of: experience oriented investment, passive experience investment, private education oriented investment, aggressive investment, and passive investment patterns. Secondly, for the patterns of investment on children, the level of academic performance was found to be the highest within the aggressive investment and the experience oriented investment types. The social relation level was found to be the highest with the experience oriented investment, with it being low in private education oriented investment and passive investment patterns. Thirdly, for the factors influencing the academic performance of the children, it was found to be higher in aggressive investment, private education oriented investment, experience oriented investment and passive experience investment compared to passive investment. Some sociological factors were also found to be influential such as mother's age, father's education, sex of children, school area of children, type of house, and income. For the social relation level of the children, the factors of the aggressive investment, passive experience investment, and the experience oriented investment as well as the sociological factors by sex of children and income level are influential.

Geopolitics or Political Geography is an essential academic field that should be studied carefully for a more comprehensive analysis of international security relations. However, because of its tarnished image as an ideology that supported the NAZI German expansion and aggression, geopolitics has not been regarded as a pure academic field and was rejected and expelled from the academic communities starting from the Cold War years in 1945. During the Cold War, ideology, rather than geography, was considered more important in conducting and analyzing international relations. However, after the end of the Cold War and with the beginning of a new era in which territorial and religious confrontations are taking place among nations - including sub national tribal political organizations such as the Al Quaeda and other terrorist organizations - geopolitical analysis again is in vogue among the scholars and analysts on international security affairs. Most of the conflicts in international relations that is occurring now in the post-Cold War years can be explained more effectively with geopolitical concepts. The post - Cold War international relations among East Asian countries are especially better explained with geopolitical concepts. Unlike Europe, where peaceful development took place after the Cold War, China, Japan, Korea, the United States, Taiwan and Vietnam are feeling more insecure in the post-Cold War years. Most of the East Asian nations' economies have burgeoned during the Cold War years under the protection of the international security structure provided by the two superpowers. However, after the Cold War years, the international security structure has not been stable in East Asia and thus most of the East Asian nations began to build up stronger military forces of their own. Because most of the East Asian nations' national security and economy depend on the oceans, these nations desire to obtain more powerful navies and try to occupy islands, islets, or even rocks that may seem like a strategic asset for their economy and security. In this regard, the western Pacific Ocean is becoming a place of confrontation among the East Asian nations. As Robert Kaplan, an eminent international analyst, mentioned, East Asia is a Seascape while Europe is a Landscape. The possibility of international conflict on the waters of East Asia is higher than in any other period in East Asia's international history.

Liquid molding processes, such as resin transfer molding, involve resin flow through a porous medium inside a mold cavity. Numerical analysis of resin flow and mold filling is a very useful means for optimization of the manufacturing process. However, the numerical analysis is quite time consuming and requires a great deal of effort, since a separate numerical calculation is needed for every set of material properties, part size and injection conditions. The efforts can be appreciably reduced if similarity solutions are used instead of repeated numerical calculations. In this study, the similarity relations for pressure, resin velocity and flow front propagation are proposed to correlate another desired case from the already obtained numerical result. In other words, the model gives a correlation of flow induced variables between two different cases. The model was verified by comparing results obtained by the similarity relation and by independent numerical simulation.

In this paper, the classical continuum mechanics is adopted and modified to be consistent with the unique behavior of micro/nano solids. At first, some kinematical principles are discussed to illustrate the effect of the discrete nature of the microstructure of micro/nano solids. The fundamental equations and relations of the modified couple stress theory are derived to illustrate the microstructural effects on nanostructures. Moreover, the effect of the material surface energy is incorporated into the modified continuum theory. Due to the reduced coordination of the surface atoms a residual stress field, namely surface pretension, is generated in the bulk structure of the continuum. The essential kinematical and kinetically relations of nano-continuums are derived and discussed. These essential relations are used to derive a size-dependent model for Mindlin functionally graded (FG) nano-plates. An analytical solution is derived to show the feasibility of the proposed size-dependent model. A parametric study is provided to express the effect of surface parameters and the effect of the microstructure couple stress on the bending behavior of a simply supported FG nano plate.
