  • 이 글은 시가의 편법을 한시와 비교한 것이다. 지금까지 시조는 주로 한시 절구의 편법과 흡사하다고 알려져 있으나, 실제는 절구와 시조는 그 형식이 짧다는 것 말고는 별로 관련성이 없다. 그보다는 율시의 수련과 미련을 제외한 가운데 대우가 되는 연, 이렇게 나누어 놓고 보면 3항시의 편법임을 알 수 있다. 이는 시조의 중장이 대우로 되어 있어 서로 깊은 상관성을 보이는 것이다. 또한 율시와 배율의 편법의 관계는 시조와 가사의 편법의 관계와 흡사하다. 가사의 편법은 시조의 중장이 길어진 것이기 때문이다. 이렇게 해서 율시와 배율, 시조와 가사에 흐르는 공통점이 발견된다.

  • 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.
