The architectural space is the involuntary place where man lives and experiences, and as a 3 dimensional space through the continuous experience with the concept of 4th dimension of time, it provides the observers with the dramatic space imagery. These kinds of space experiences are experienced mentally and perceptively through the physical elements of inner and outer space of the architectural buildings, and this space imagery is created here by all the space composing elemensts of the building. These space experiences are caused by the changing processes of the space characteristics, and the observers perceive the changes in space characteristics. These changing processes of inner and outer space, space versus space, and unit space, which are perceived by the observer, could be called as 'the transition' and thd changes of the space characteristics as 'the transition characteristics'.

Earth's bow shock is a transition layer across which properties of plasmas change irreversibly. Although some features of the bow shock are well described by continuities of fluxes of various macroscopic quantities, particle dynamics across the transition layer is very complicated. Observed phase space distributions show multiple ion beams and partially thermalized ions around the transition layer. In some cases, both hot magnetosheath ions and cold solar wind ions simultaneously exist in the magnetosheath. Electrons around the transition layer usually have flat-top distributions with temperature anisotropy. From the observed properties of the phase space distributions we will discuss thermalization processes that occur across the shock transition.

Recently, a lower levels space has turned into a mediating space where people can experience urban spaces directly and it has revitalized communication between the city and company and also it has changed itself newly. In addition, this space which is connecting interior and exterior spaces of company's buildings can attract people living in the downtown as shock-absorbing and transitional space and it is getting more important part in urban context these days. Through case studies of corporate office space planning characteristics derived lower levels and to provide direction for the lower levels of the corporate office space planning purposes of the present study. Therefore, I establish the concept of the public good corporate office space and transition space, the concept of transition through the first Theoretical Methods. I investigate the properties of the transition area is used as the target for completion of the current construction culture destination since 2000, winning the corporate office, I have been talking about the characteristics of the corporate office along the lower part of the last PPS assessment criteria to apply to the building. PPS by applying an assessment factor can be derived for building enterprise case studies and analysis of the results the following conclusions about the use of publicity and transition space. First, lower levels of corporate office space had been applied to the use and activity in a very important project characteristics. Second, corporate office space, lower levels of access and linkages are important. Finally, in terms of public characteristics transition space is a important characteristic for low-rise space of headquarter buildings.

Mugiyeondang(舞沂蓮塘) is the garden that the provincial noble family in Yeongnam(嶺南) has constructed since the late Joseon period. Mugiyeondang is well known as a typical case of traditional garden in Joseon period. But it is also an exceptional case because of its informal layout that infers gradual space transition. This study aims to establish the historical story of the garden beyond the superficial description about existing spatial status and literature materials. Mugiyeondang had been constructed by seven generations of the family during two hundred years, and there were significant events at every transition points. The figure and name of elements reflects each historical change of the family. Mugiyeondang is an important case to notice that a garden was not just a subsidiary space for mere leisure life of the gentry of Joseon period, But it was an important for some families as their representative and symbolic space.

Properties of plasmas that constitute the plasma sheet in the near-Earth magnetotail vary according to the solar wind conditions and location in the tail. In this case study, we present multi-spacecraft observations by Cluster that show a transition of plasma sheet from cold, dense to hot, tenuous state. The transition was associated with the passage of a spatial boundary that separates the plasma sheet into two regions with cold, dense and hot, tenuous plasmas. Ion phase space distributions show that the cold, dense ions have a Kappa distribution while the hot, tenuous ions have a Maxwellian distribution, implying that they have different origins or are produced by different thermalization processes. The transition boundary separated the plasma sheet in the dawn-dusk direction, and slowly moved toward the dawn flank. The hot, tenuous plasmas filled the central region while the cold, dense plasmas filled the outer region. The hot, tenuous plasmas were moving toward the Earth, pushing the cold, dense plasmas toward the flank. Different types of dynamical processes can be generated in each region, which can affect the development of geomagnetic activities.

The society changes very fast from the extended family system to the nuclear family system, as increasing a one-child family for the low birth-rate. Thus, it causes that the education, having been performed inside of the family group, is performed outside of the family nowadays such as an infant educational institution. Fundamentally, the space of educating infants must be considered their behavior and meet their needs. For infants, playing is not only studying, but also is related to physical, intellectual and emotional development. Therefore infants in a qualifiedly good playing environment, are easy to focus on their playing. But, variety of playing activities can help improve infants' development physically, socially, emotionally, linguistically and intellectually. So far, an infant educational institution has provided a general education than a special educationally considering their age and status of a development. However, it is necessary to provide an integrated and well-organized place for each infant because their playing is a studying and education that will be based of individuals' character when they are grown up. The objective of this thesis is to study on the new transition space for infants of their physical activities. For this study, at first, it is important to understand what are the points of well-built kindergarten around the world. They have the flexible space in common. The transition(flexible) space will be a solution for space for infants' development.

This paper presents an improved guidance algorithm for autonomous underwater vehicles (AUV) in 3D space for generating smoother vehicle turn during the course change at the way-points. The way-point guidance by the line-of-sight (LOS) method has been modified for correcting the reference angles to achieve minimal calculation and smoother transition at the way-points. The algorithm has two phases in which the first phase brings the vehicle to converge to a distance threshold point on the line segment connecting the first two way-points and the next phase generates an angular path with smoother transition at the way-points. Then the desired angles are calculated from the reference and correction angles. The path points are regularly parameterized in the spherical coordinates and mapped to the Cartesian coordinates. The proposed algorithm is found to be simple and can be used for real time implementation. The details of the algorithm and simulation results are presented.
