  • The purpose of this study is to verify the effectiveness of the biotope model in applying and developing Korean urban forests. We found that there are 17 biotope assessment indicators, including forest layer structure, site conditions, ratio of broad-leaved trees, species richness, etc. In terms of correlation analysis between indicators, the stand ages and the period of space formation have the highest relativity(coefficient 0.684). On the other hand, indicators that have negative relativity are layer structure and risk, with a coefficient of -0.412. Ten models were developed for the multiple regression analysis. 10 variables(site conditions(X2), ratio of broad-leaved trees(X3) and so forth except layer structure(X1), species richness(X4)) were found to have a 95% significance level The results from comparing the regression model and adding-up estimation matrix, the most accurate one was Model 3, which has a 91.7% out of the 10 models. However more monitoring will be needed to improve the accuracy of models for the Korean urban forests in future.

  • According to my research about Janlgu(絶句) and Sijo(時調), they have not used the same methods to make the phrases (句) within of Sika(詩歌). In this thesis I shown that Ullsi(律詩) and Sijo have used a similar methods to make the phrases. However. the main assertion of this thesis is to show the fact that Sijo has changed into Kasa(歌辭) the same way Ullsi has changed into Baeull(排律). I have found that Ullsi and Baeull are different from Sijo and Kasa. Jaulgu and Sijo don't have any similarities except the use of their short sentences. Ullsi is similar to a poem with three lines in each verse. To separate the poem with three lines in each verse to three parts of the first stanza. the last stanza(結聯). and how the middle stanza contrasts (related to the phrase or stanza of poems which have a pair.). I have found out how the poem with three lines in verse is made. The middle phrase of Sijo is made up of complete opposites. I think that Sijo has the same relation. with Ullsi. Also. Kasa is made up opposites. Antithesis is a kind of way to make Ullsi by phrase and clause. I have found the antithesis in the middle phrase of Sijo. Kasa is made up antithesis and is the relativity of Ullsi and Baeull and the relativity of Sijo and Kasa are explained by antithesis. As Ullsi changed to BaeulL Sijo has changed to Kasa. They have the same method of making phrases. Some have insisted that Sijo was not from Hansi. I don't agree with that. Even if Ullsi is not from Sijo. this thesis has proven that the method of making phrases of Ullsi and the method of making phrases of Sijo are very similar. In this thesis. I have found out that Ullsi and Baeull are very similar with Sijo and Kasa. I think that these old types of Chinese poems have affected Korean Culture. So. in this thesis. I have tried to show just a little fact about this old type of Chinese poems and how it has affected Korean Culture.

  • We analyze the clustering of large scale structure in the Universe in a model independent method, accounting for anisotropic effects along and transverse to the line of sight. A large sample of 690,000 galaxies from The Baryon Oscillation Spectroscopy Survey Data Release 11 are used to determine the Hubble expansion H, angular distance D_A, and growth rate GT at an effective redshift of z=0.57. After careful bias and convergence studies of the effects from small scale clustering, we find that cutting transverse separations below 40 Mpc/h delivers robust results while smaller scale data leads to a bias due to unmodelled nonlinear and velocity effects. The converged results are in agreement with concordance LCDM cosmology, general relativity, and minimal neutrino mass, all within the $68{\backslash}%$ confidence level. We also present results separately for the northern and southern hemisphere sky, finding a slight tension in the growth rate -- potentially a signature of anisotropic stress, or just covariance with small scale velocities -- but within $68{\backslash}%$ CL.

  • Spatial perception and spatial structure that focus on psychological effects produce a real force through the medium of space that can control human actions, even their psychology. The job of understanding the characteristics and effects of architectural spaces that recognize the relationship between architecture and human beings, including the psychological dimension, is an alternative search for quality spaces that can increase the mutual relationship between space and human beings. This paper introduces two propositions called "space" and "psychology" in order to discover a meta-pattern connecting space and the human mind with the aim of systematizing that internal network and establishing a new architectural system concerning space and human beings. This paper also proposes a method of accessing physical spaces that can affect psychological states through a conceptual substitution called "extension," with the aim of discovering the implications inherent in such extensive relationships and proposing a methodology of organizing psychological spaces based on the characteristics of that extensive connection. The means of extensively connecting psychological spaces were classified into the three categories of memory system, sensory system, and motor system, and their corresponding extensive connection characteristics called "simultaneous relativity," "non-mediated immediacy," and "purification process" were also derived. These characteristics accelerate the changes in psychological intensity and function as principles that organize psychological space.

  • The ethnic image in modern fashion can be interpreted as a trend of post-modernism, which appeared after modernism's established style. It has relativity, pluralism and variety, and it tries to revive style of the past. This makes style that borrows and combines image and style of different era and culture as distinctive feature, and in turn is expressed by a new image that is combined with the country's clothes. Also, thanks to the customers who are tired of artificiality and convenience, gift of modern science and technology, simple and natural sensitive marketing and being 'raw' are getting popular as new trend. Today's ethnic image is not merely borrowing visual, superficial image of culture and clothes of other ethnic group, but pursuing natural as purely created by human senses rather than being polished. In terms of ethnic image's formative beauty and aesthetic value, foreign and domestic collections are compared. But for domestic image, only Korean ones are researched, and for foreign designer's fashion image, there are ethnic styles of Japan, China and Korea. Although the documents of domestic designers that I investigated is not sufficient, canonic simple being of oriental image that is seen by the westerners is summarized.

  • The purpose of this research is to develop rapid setting cement latex modified concrete (RSLMC) which will be used to overlay bridge deck for maintaining and repairing. The main experimental variables were the types of rapid setting cement and variation of latex and antifoam agent contents were selected as admixture factor, then the properties of workability and strength development and durability properties were investigated. The results of this study show that latex content give increment of a slump due to surface tension in polymer particles and reduce unit weight of water for preservation of workability. In addition, When no and 1.6~3.2% antifoam agent were mixed, 8%, 2.0~3.8% were respectively obtained. An increasing the amount of latex produced concrete with increased flexural strength, but with slightly lower compressive strength. Rapid chloride permeability and freezing-thawing test carried out. As a results, according to increment of containing ratio antifoamer, strength of RSLMC increase, permeability showed lower value than ignorable 100 coulombs. Also, in the case of more than antifoamer 1.6%, the relativity dynamic modulus is mantained more than 90%, but in case of 0, 5%, it decrease. In consequence, with the view of strength and workability of RSLMC, it is considered that appropriate content ratio of antifoam agent and latex solid are respectively 1.6% by latex weight, 15% by cement weight.
