익산지역에서 자동 및 수동채취방식에 따른 강수의 화학적 특성 비교

강공언 한국대기환경학회 2004 한국대기환경학회지 Vol.20 No.3

In order to understand the precipitation acidity and chemical composition of ion species in Iksan area as well as to know the difference of chemical characteristics in precipitation samples from the viewpoint of precipitation sampling method, precipitation samples were collected by wet-only automatic precipitation sampler and hulk manual precipitation sampler in Iksan, from March 2003 to August 2003. The mean pH of precipitation was 5.0. There was a little significant difference in the mean value of pH between automatic and manual sampler. However, pH values of some precipitation samples were lower in automatic sampler than in manual sampler, especially in case of precipitation samples with small rainfall for March 2003. The mean concentrations of each ions in precipitation were generally a little higher in precipitation samples collected by the manual sampler than in those collected by the automatic sampler because of accumulation of dry deposition on the surface of glass funnel installed at the manual sampler during the sampling period of no rainfall. Dominant species determining the acidity of precipitation, were NH₄+ and nss-Ca^(2+) for cations and nss-SO₄^(2-) and NO₃- for anions. The mean concentration of NH₄+ and nss-Ca^(2+)j were 31 μeq/L and 9 μeq/L for the automatic sampler and 40 μeq/L and 16 μeq/L for the manual sampler, respectively. In addition, nss-SO₄^(2-) and NO₃- were 27 μeq/L and 13 μeq/L for the automatic sampler and 32 μeq/L and 17 μeq/L for the manual sampler, respectively. Although the concentrations of the acidifying ions of nss-SO₄^(2-) and NO₃- were about 3 times higher than those for foreign pristine sites, precipitation acidity were estimated to be natural due to the neutralization reaction of the alkaline species of NH₄+ and nss-Ca^(2+) with its higher concentrations. Considering the ratios of nss-SO₄^(2-)/NO₃- and NH₄+/nss-SO₄^(2-), it was found that ammonium sulphate was dominant in Iksan precipitation. The major non-sea salt ions were maximum concentrations for March, but decreased with increasing of precipitation amount.

漱石作品における文體の變遷について : 「如し」を例として

羅工洙 全南大學校 人文科學硏究所 2001 용봉인문논총 Vol.30 No.-

근대 일본 소설의 거장인 나쓰메 소세키(夏目漱石)의 작품을 통해서 그 문체의 변화를 고찰하였다. 지금까지의 연구와는 다른 방법으로 「如し」를 통해서 고찰하였다. 그 내용을 정리하면 다음과 같다. ① 「如し」 와 「 樣だ」 의 사용률을 볼 경우, 초기작품에 비교적「如し」 의 비율이 높고, 후기작품으로 갈수록 점점 줄어든다. ② 「如し」의 활용을 볼 경우, 초기작품에 훈독문에서 많이 사용되는 종지형이 보이지만 후기 작품에는 사용되고 있지 않다. 그리고 동사 연용형과 접속할 경우, 훈독문에서 많이 사용되는 격조사 「が」 가 초기작품에 많이 있지만, 후기작품에는 사용되지 않는다. ③ 「みたやうだ」「みたいだ」를 볼 경우, 전 작품에서 「みたやうだ」가 보이지만, 후기작품에서 신 어법인「みたいだ」가 사용되고 있다. 이러한 결과가 나온 배경은 소세키는 어릴 적부터 한문을 배웠고, 기본적으로 한문의 소양이 깊었기 때문이다. 많은 한시를 남긴 것으로도 그 능력이 있음을 알 수 있다. 소세키는 작가활동을 타인보다 늦게 시작하여, 이미 언문일치의 확립.성립의 시기에 출발하였고 작가자신도 언문일치에 지대한 관심을 갖고 있었다. 그러나, 한문에 소양이 깊었던 소세키는 언문일치의 문장에 한문맥과 같은 문어적 표현을 써 넣고 있다. 그것이 특히 초기문장에 그 빈도가 높고, 후기작품에 갈수록 작아지는 것이다. 짧은 작가생활이었지만, 점점 구어화 할려고하는 움직임이 있었다.

In order to investigate the statistical analysis of ambient suspended particle at Seoul in Korea, airborne particulate matters were collected by High-Volume Air Sampler from April 1988 to May 1991, and size distribution of the aerosols were measured by filters on nine stages Andersen Air Sampler from January 1990 to December 1990. And with respect to seven components in the total suspended particulate, the factor analysis was performed. As a result of factor analysis by using the varimax rotation method, the chemical components in the TSP were able to characterize with two principal factors. The first factor (Factor 1) was considered to be a factor indicating the contribution of natural sources and the second factor(Factor 2) was a factor indicating the contribution of anthrophogenic sources. For concentration of size distribution measured by Andersen Air Sampler, tne factor analysis was also performed. As a result of factor analysis by using the varirnax rotation method, particle size distribution of atmospheric particulate was divided into two groups, coarse particle group was made by particles lager than 2.1㎛ in diameter and fine groups smaller than 1.1㎛ in diameter.

韓方藥의 藥理

김공수,유광석,한종현 圓光大學校 韓醫學硏究所 1993 원광한의학 Vol.3 No.1

Western medical science places the highest priority on scientific analysis and research. Therefore, Western medicine has obtained good results by estabilishing specific countermeasures against individual diseases, with causes thoroughly analysed and positively diagnosed. On the other hand, Oriental medical science has been particular about intergrating the part into the whole, in general. The superiority and/or inferiority of one approach over the other cannot be determined by either of the two medical sciences, due to the fundamentally different bases. Therefore, the two medical schools must now be combined, by distinguishing and isolating the respective characteristics in treatment, first seperatly and then combined, during a transition period. If Western medical science may be likened to a piece of brick, as its substance can be easily defined, Oriental medical science may be likened to cement. If one were to build a medical science house for the 21st century, a comfortable house could be built using either to the medical sciences as building material, Western medical science, corresponding to brick, or Oriental medical science, corresponding cement. Bricks are easily dimensioned and standardized, whereas cement is not only fixed in from, but requires a great deal of experience for its successful use. Howerever, both items are essential as building materials. It may be held that we can successfully treat the complicated pathogens of diseases afflicting the aged and chronically ill patients by making full and intelligent use of both medical sciences.

Spandex is man-made elastomer fiber. Chemically, polyurethane is produced by interaction of Glycol and Diisocyanate. From a physical point of view, these Spandex fibers owe their elasticity to the same thermodynamics as rubber, therefore, the high degree of fabric stretch availability permits its use in a wide range of textile fabrics. Particular interests are to improve the dyeing properties and to find out the dyeing mechanism. So, it is the purpose of this paper to present technology which will permit these yarn to be dyed with selected dyes and to describe the dyeing mechanism.

수학 모델을 이용한 체조 선수의 인체 분절의 관성 특성

尹恭和,朴宇奎 慶一大學校 1997 論文集 Vol.14 No.2

This study was conducted to determine the inertial charactristics of the body segment such as mass, mass center, and moments of inertia with respect to the three principal axes of rotation passing through the mass center of Korean male gymnasts using a mathematical model. The subjects chosen for this study were 7 male university gymnasts of 18-21 years of age. Two 35mm cameras enabled simultaneous photographs of the body to be made. The optical axes of the cameras were horizontally aligned to provide anterior and lateral views of the body. The photographic records were analyzed by reading the image using the scanner, defining the contours and required points of the segments using the mouse, and computing the inertial charactristics. The model of the human body described in this study was an advancement over previous mathematical models in that a representation of the segments by elliptical disc 5 mm wide followed the shape fluctuation of the body more closely. The accuracy of the method was evaluated by comparing the estimates of total body mass with the mass as measured on weigh scale. Table 2 provides the results of this study as mass, mass center, and moments of inertia of male gymnast body segment.
