The purpose of this paper is to verify the spatial distribution difference between formation and dissolution of start-up firms related to life-cycle. For this purpose, a Korean business directories and information on business closures were used, and location information, starting time, and closure time of start-up firms in the Seoul metropolitan region from 2007 to 2009 were generated in this study. It applied The spatial distribution analysis methods on the formation and dissolution of the start-up firms included Barcki measurements and global spatial autocorrelation. The total number of start-up firms was 5,810, and their five-year survival rate was 77.25%. The dissolution pattern of the start-up firms was dispersed more than their formation pattern in each of the Seoul metropolitan regions, the city of Seoul, and the city of Incheon-Gyeonggi province. In addition, differences between the formation and dissolution patterns according to size and industry category of the firms were confirmed.

A traditional settlement, in a long history establishment, is appeared to be configured of the people and their life in the areas. This is, a positive aspects, compared to most of the city in these day which is monotonous aspects. The purpose of this research deals what is the formation process and spatial character in urban settlement of Naju city, and how to applicate in a modern city context. For the research goals, it analyse an old Naju Castle area, transformation of the land use through the cadastral survey, and spatial character through step by step in chronical approach. The process of change can be seen in the devide pattern in a lot, formation and extension of a private road, and formation and change of the road; This shows how to changes traditional settlement in a old urban areas of Naju city. A now road system in old area, as a conflict, push the change of the spatial organization, and the balance of the identity of a traditional settlement and a new change as a convenient needs, it is a key point to get ideal settlement.

The results of the research were as follows: The entire space of the village was based on natural formation in its initial formation stage. The traditional location conditions and environment were equipped with the possibility and conditions for the development of the village. Spatial boundaries were mostly divided by natural topography. The quantify of lots diminished in spatial structural factors, while the division of roads by hierarchy in terms of size became explicit. Alleys, as the minimum hierarchial nit, were degraded. The residence unit was focused on economic efficiency. Communal use facilities showed an external relations trend as central facilities. The land, unit residence and communal facilities approached the high hierarchial roads. The communal facilities showed relatively higher independence compared to the residence units. The spatial structural changes followed traditional life style in the initial stage of village formation; however, social elements mainly impacted on the changes. Since reform opening, economic elements were major causes of changes, while construction conditions, life style, and awareness of structures impacted upon the changes. Thus, the economic element is the major change element in the Korean Villages, even though other elements will also become diverse.

This paper presents a modified track guidance algorithm for formation flight of multiple UAVs. The suggested guidance algorithm is the spatial version of the first order dynamic characteristics for a time-dependent system so the algorithm is able to generate a path without overshoot to track the desired line. A crucial design parameter is a spatial constant that controls the shape of the convergence to an assigned flight path similarly to a time constant. Reference flight trajectories are designed based on a two-dimensional vehicle model, and the performance of the proposed guidance law is verified by numerical simulation using rigid body UAV dynamics with MATLAB/Simulink Aerosim Blockset.

We present Palomar/SWIFT integral field spectroscopy of z~0.2 strong $H{\alpha}$ emitters identified in the Sloan Digital Sky Survey. The large Halpha equivalent widths as well as the huge specific star formation rates of these galaxies are comparable with that of z>4 Lyman break galaxies, thus understanding the gas kinematics and the distribution of massive stars in these systems will help to obtain a better understanding of high-redshift star forming environments and the growth of massive galaxies. We measure the velocity dispersion across the entire galaxy, estimate the number density and the spatial distribution of massive stars from the emission line morphologies. The role of minor mergers in powering star formation is investigated as an alternative to cold flow driven star formation.

Tension members is a type of effective structural member, which is often used in large span structures. The structure systems composed with tension members are combined in various way and specific formations. So, there are need to research into the formations of tension structure and the type of adaptation in tension structure architectures. The structure systems with tension members were considered as tension main system, vector system and tension supported bending system, comprehensively. And tension structures were classified into the formation of tension structure with uniaxial or multiaxial line tension member, with surface member, with hybrid member of line and surface, concerning the flow of tension force. In each the formation of tension structure, the typical adaptations to architecture were also investigated through architecture examples. The type of the formation can be used to plan an architecture with respect to the flow of tension force and structural feature.

User and media are in close coalition with each other in the 21st century's era of New-Media. The new users exposed to the New-Media environment have a complete understanding of the digital media environment, and are also taking on the role of an active identity in the formation of culture in new media. In the field of spatial design, creative spatial interfaces designed through various methods derived from the New-Media environment and technology that weren't even imaginable in the past ultimately came to exist in a mutual relationship with the user, the people. This study is in the same context as studies looking into the establishment of design in media art and digital media space in the New-Media environment. Media art is an outcome arising from the demand towards new art combined with the attempts towards accepting various media as a means for artistic expression. Media art seizes to being a mere part of art, but more. This study aims to look into the theoretical basis of New-Media and define the design process through the expressional characteristics and triggered thoughts thereof. Lastly, the results of the research will be put together to produce the final results. Such analysis process will be the basis of the creation of a new paradigm and spatial thought, and allow people to be concerned about the various changes in spatial formation.

In this work, we analyze the spatial patterns of a predator-prey system with cross diffusion. First we get the critical lines of Hopf and Turing bifurcations in a spatial domain by using mathematical theory. More specifically, the exact Turing region is given in a two parameter space. Our results reveal that cross diffusion can induce stationary patterns which may be useful in understanding the dynamics of the real ecosystems better.
