Computer applications for engineering design evolve rapidly. Many design frameworks were developed by the simulation based systems so that organizations could achieve significant benefits due to cost reduction in designing. However, today’s transient design issue requires being adaptable to more complicated and atypical problems. In this paper the Multidisciplinary Language Runtime (MLR) design framework is developed. The MLR provides flexible and extensible interface between analysis modules and numerical analysis codes. It also supports Meta Modeling, Meta Variable, and XML script for atypical design formulation. By applying object-oriented design scheme to implement abstractions of the key components required for iterative systems analyses, the MLR provides flexible and extensible problem-solving environment.

Plate tectonics, with the continental drift theory and later strongly supported by the sea-floor spreading theory with evidence of paleo-geomagnetic fields, ocean floor sediments, successfully explained the slow but continuous movements of rigid lithospheres in geological time. Initially, plate motions were described as relative movements between adjacent plates, mainly based on paleo-geomagnetic reversal data. The advent of space geodetic techniques in the 1980s enabled direct measurements of plate velocities and assessment of deformations within certain regions. In this review, early relative plate motion models are briefly summarized, the no-net-rotation frame theory and corresponding models are explained, and the characteristics of the most recent models that incorporate intraplate deformation are described. Additionally, the plate motion section of the International Terrestrial Reference Frame is introduced, and a few recent case studies of local plate motion are briefly described; for example, in South America, Europe, Antarctica, and Turkey. Finally, studies of plate motion in northeastern Asia focusing on the Korean Peninsula are introduced.

This paper's purpose is to seek to grasp how Descartes demonstrates proofs of God's existence on the basis of his works especially Meditations. To consider these points, I shall explore first, second, third proofs that are present in his works, and contents related to God. Descartes argues that there is idea of God within me, but it is God, which is first proof. On the basis of this fact, Descartes shows only God is the cause of thinking self who has idea of God(second proof), both of them are called Cosmological argument. To investigate this, at first he states that representative reality that is different from formal reality sets a kind of hierarchy, the degree of this reality is equally applied to cause and effect, consequently to the cause of my idea or existence(God). From Meditation V, third proof which is called Ontological argument, Descartes examined a supremely perfect God can't be separated from God's existence(perfection) just as surly as the certainty of any shape or number, for example triangle, namely it is quite evident that God's existence includes his essence. Through these processes I shall examine following points: the way of having Descartes' proofs of God's existence itself is not only exposed, God's existence who guarantees cogito ergo sum which is never doubted, despite doubting all things that is outside, is but also postulated; Proofs for the existence of God are an ultimate source of ensuring the clear and distinct perception of human reason, Descartes uses reason suitable for non-christians instead of faith suitable for Christians for these methods, which are similarities with the traditional views on the one hand, but nevertheless there are some of discontinuities establishing authority or power of the first philosophical principle to which God is subjected, on the other.

In religious studies, soteriology is a belief system that aims to compensate and solve the existential suffering of human beings through a doctrinal system of healing, liberation, and salvation as advocated by various religions. The purpose of this study is to understand the soteriology of Dasesoon Jinrihoe, a Korean new religion, and to understand its characteristics. The soteriology of Daesoon Jinrihoe is closely related to the theory of The Reordering Works of Heaven and Earth. The Reordering Works of Heaven and Earth is a doctrinal system in which the Supreme God, Jeungsan, was incarnated into a human body to rescue the world and creation and to achieve this, he had performed various religious works. In addition, the soteriology of Daesoon Jinrihoe is linked to the theory of orthodox lineage spanning Jeungsan to Jeongsan and lastly to Udang. The work of salvation performed by Jeungsan is settled by Jeongsan who systematized it into methods of practice. This soteriology has distinctive differences separating it from traditional religious traditions. First, it shows the characteristic of offering salvation through a supreme, personal God. Second, Jeungsan is seen as having changed the cosmic law and provided the basis for the world and creation to be saved. Finally, it proposes a theory that saving the world and creation is to be achieved through the principle of the Resolution of Grievances.

Recurrent enhancements of relativistic electron events at geosynchronous orbit (GREEs) were observed in 2006. These GREE enhancements were associated with high-speed solar wind streams coming from the same coronal hole. For the first six months of 2006, the occurrence of GREEs has 27 day periodicity and the GREEs were enhanced with various flux levels. Several factors have been studied to be related to GREEs: (1) High speed stream, (2) Pc5 ULF wave activity, (3) Southward IMF Bz, (4) substorm occurrence, (5) Whistler mode chorus wave, and (6) Dynamic pressure. In this paper, we have examined the effectiveness about those parameters in selected periods.

In Laozi Tao(道) is not only the universal law of all existence but the eternal law of morality. In Laozi Tao as the eternal law of morality is the absolute criteria of value-judgement. In this respect in Laozi Tao is the perfect value or the absolute criteria of value-judgement. And so someone can evaluate Laozi's perspective on the theory of value is value-absolutism. Nonetheless, Laozi allows all theories of value in Laozi. Laozi's thought on the value is indifferent to what kind of value one has. But Laozi's ideal of the theory of value is value-universalism through Tao as the absolute criteria of value-judgement. So in Laozi the perspective on value is the universalization of value-absolutism. In Laozi, the medium of value-universalism is being of Sage(聖人) and all human's inpersonation of Teh(德). If this two conditions fulfilled, all human beings can reach the state of "subtle identification(玄同)" and can be sages, and value-universalism take the form of valuelessism.

Whitehead's metaphysics and philosophy of nature rest on his awareness of the metaphysical problem of the relation between "I", the "creative advance" and forces of the universe. Whitehead attempted to systematize human experience of the world based on logical explorations. In this context it is important to note that his discussion of proposition and language is closely connected with his works on a systematic theory of nature. Whitehead proposes a metaphysical concept of proposition also based on the creative advance of the universe. His theory of proposition is designed to show that human language is constructions of the relations between logical and real events in the creative universe which refer to a particular point of view. In this view, a variety of verbal possibilities in the multiple worlds can be realized in the same proposition. For Whitehead the emergence of novelty in the function of proposition is an essential property of the creative universe. This paper will try to give a discussion to Whitehead's theory of proposition with regard to the emergence of nature. Especially I emphasize in this paper Whitehead's idea and meaning of proposition for the development of the creative advance of nature as one aspect of particular importance.

The regulation of satellite remote sensing is generally included with the scope of statutes governing outer space activities. But not all states opted for dedicated satellite remote sensing regulation. The decision whether to do so depends in part on the specific capabilities of national satellite remote sensing programs. Five states that have dedicated statutes governing operations with remote sensing data are the United States, with its developed Landsat regime (the Land Remote Sensing Policy Act of 1992, LRSPA), Canada, with its Remote Sensing Systems Act, Germany, with its Satellite Data Securities Protection Act (SatDSiG), France, with its Law on Space Operations (LOS), Japan, with its Act on Ensuring Appropriate Handling of Satellite Remote Sensing Data. The major purpose of this article is to shed light on some legal issues surrounding remote sensing activities by comparative review. The paper analyzes international conventions or soft law and national law and policies relating to satellite remote sensing. It also offers some implications and suggestions for regulations of satellite remote sensing operations and satellite data.

Dynamic analysis of laminated beams with a embedded damping layer under tension or compression axial load is investigated. Improved Layer-Wise Zig-Zag Beam Theory and Interdependent Kinematic Relation using the governing equations of motion are incorporated to model the laminated beams with a damping layer and a corresponding beam zig-zag finite element is developed. Flexural frequencies and modal loss factors under tension or compression axial load are calculated based on Complex Eigenvalue Method. The effects of the axial tension and compression load on the frequencies and loss factors are discussed.

Low-speed gas flows around a micro-scale flat plate are investigated using a kinetic theory analysis. The Boltzmann equation simplified by a collision model is solved by means of a finite difference approximation with the Discrete Ordinate method. Calculations are made for flows around a 5% flat plate with a finite length of 20 microns. The results are compared with those from the Information Preservation method and a continuum approach with slip boundary conditions. It is shown that three different approaches predict a similar basic flow patterns, while the results from the present method are more accurate than those from the other two methods in details.
