  • We researched the change of astigmatism power when the fixation point moved from far distance to near distance. Astigmatism power was measured by using both eyes open-view auto-refractometer. We divided the ages between 5 and 67 years old into 12 groups with 1,598 healthy eyes(male-698 eyes and female-900 eyes) without eyes problems and experiences of eyes operations. The mean power in far astigmatism showed that with-the-rule of the total astigmatism: -0.79D, with-the-rule of the corneal astigmatism: -1.07D and against-the-rule of the residual astigmatism : -0.79D were found most respectively. The correlation between cornea astigmatism and total astigmatism was y=0.7493 x + 0.5661 r=0.6510, residual astigmatism and total astigmatism was y=0.248 x - 0.5926 r=0.2598 and corneal astigmatism and residual astigmatism was y=-0.4439 x - 0.1813 r=-0.5551 in the far distance. The mean power in near astigmatism showed that with-the-rule of total astigmatism : -0.92D, with-the-rule of corneal astigmatism : -1.12D, against-the-rule of residual astigmatism : -0.87D were found most respectively. In the near distance, The correlation between corneal astigmatism and total astigmatism was y=0.6872 x + 0.5934 r=0.6204, residual astigmatism and total astigmatism was y=0.303 x - 0.6066 r=0.3165, corneal astigmatism and residual astigmatism was y=-0.46 x - 0.0626 r=-0.5322. When the fixation point moved far distance to near distance, the differences of power according to the type of astigmatism were total astigmatism: $-0.07D{\pm}0.44D$, corneal astigmatism: $-0.04D{\pm}0.54D$ residual astigmatism:$0.01D{\pm}0.53D$. Most of astigmatism refractive power was increased except for oblique-the -astigmatism. When the fixation point moved far distance to near distance, the change of astigmatism refractive power showed total astigmatism: 540 eyes(33.7%), corneal astigmatism: 638 eyes(39.9%), residual: 841 eyes(52.6%).

  • This paper is examining the ideological underpinnings of Park Jin-young[朴震英]. He was intellectual activity is based on Haman[咸安] Gyeongsang-namdo[慶尙南道]. And He was causing the Righteous Army[義兵] saved the country from the crisis of Imjin War[壬辰倭亂, 1592~1598] and the Byongja War[丙子胡亂, 1636~1637] in Mid-Joseon[朝鮮] Dynasty. Therefore, he had to practice patriotism and love people. The purpose of this paper is centered on the acts of Park Jin-young to focus on its ideological foundation to be sure. A cause[大義名分] was laying on the side and the real meaning of the terms of participation and his a far-sighted view [達觀] ever conduct of life[處世] divided into such discussions were developed. In addition, the formation of his ideas around the Jung gu[鄭逑] influenced correlating it with the teacher and student relationships were investigated. Park Jin-young is Im-Byeong War[壬丙兩難] since emerged on the Joseon [朝鮮] Social Jon-ju[尊周] thought was one of the representative figures. His mentor Jung gu was the cause, seriously. And he cause, the influence of the teacher very seriously here was typical of that era. The people loved teacher. And his disciples to overcome difficulties that influence the Righteous Army sought to raise the country. His teachers have taught him Confucian influence. And behave appropriately when life. Park Jin-young acted appropriately when affected by such a life. Consequently, he was a true intellectual in those times.

  • This article addresses how the British Empire administered the discipline of space in nineteenth century Ireland. Space control is a part of modern disciplinary practices. I approach this issue in light of the two modern mapping of space: the geometric mapping of space and the Romantic mapping of space. The former, as seen in map-making, is characterized by imposing a standardized, stratified grid on space by eliminating local characteristics of nature. On the other hand, the latter, as shown in picturesque landscaping, aims to balance a close-up observation of nature and a far-sighted view of it, with the result of creating an ironic tension of local diversity and perspectival totality. These modern disciplinary projects of space repeat themselves in the British management of the colonized Irish territory. As the British conquer other lands, they put to good use both geometric and Romantic disciplinary methods of space. Supervising the Ordnance Survey of Ireland from 1824 to 1846, Thomas Frederick Colby, British Director of Ordnance Survey, made a mathematically strict and scientific mapping of Ireland as a scale of six inches to one mile. Parallelled to this geometric colonization of space, the Romantic colonization of space is efficiently used for the Empire's management of Ireland as well. British tourists and pro-unionist Anglo-Irish landed gentries transform it into the nature of picturesque beauty; Ireland's wild boglands turn aesthetically into desolate but beautiful scenery. Picturesque landscape in England is reborn as an aesthetics of desolation in Ireland.

Effects of Foliar Treatment of Underground Water, Chitosan Solution, and Wood Vinegar Solution on Residual Procymidone Removal in Altari Radish (지하수, 키토산 및 목초액의 엽면살포에 의한 알타리무 체내의 잔류 Procymidone 제거효과)

  • For this study, Smilex powder, a pesticide, was sprayed on the Altari radish, and then underground water, Chitosan solution (${\times}$500), and wood vinegar solution (${\times}$1000) were evenly sprayed on the Altari radish respectively. Samples of Altari radishs for residual pesticide analysis were taken two hours, 1 day, 7 days, and 15 days after treatments, and the detectable concentration and degradability of procymidone, the pesticide residue, were measured. The results obtained are as follows: 1. When detectable concentration of procymidone within the altari radish was measured, treatment plots sprayed with underground water, Chitosan solution (${\times}$500), and wood vinegar solution (${\times}$1000) were found to show lower detectable concentration than the non-treatment plot which was sprayed with pesticide only. Especially, the treatment plots sprayed with Chitosan solution (${\times}$500), and with wood vinegar solution (${\times}$1,000) showed lower values than the average. 2. When the degradability of procymidone within the Altari radish was measured, the plot treated with Chitosan solution (${\times}$500) and the plot treated with wood vinegar solution (${\times}$1,000) were found to have relatively higher degradability of procymidone. There were not much differences among testing materials in the degradability of residual pesticides. However, the plot treated with Chitosan solution (${\times}$500) showed higher degradability. In terms of average degradability with time, degradability increased sharply 7 days after the foliar application of testing materials. 3. When the daily far-sighted view survey was conducted in order to find out growth disorder and damage on the Altari radish plants by the treatment of un-derground water, Chitosan solution (${\times}$500), and wood vinegar solution (${\times}$1,000), no symptomatic physiological disorders was observed on all the plants tested during the whole growing season at the tested concentration level.
