강의 상류부에서도 사력퇴가 잘 발달한 홍천강의 상류 유역 중 하나인 두촌천 유역을 대상으로 역과 모래를 분석하였다. 이를 통해 각 구간별 사력퇴의 발달 양상과 퇴적물의 차이를 비교해 보고 상류에서 하류로 이동되는 퇴적물의 변화양상을 살펴봄으로써 소유역 내에서도 다양하게 나타나는 하천의 지형발달 특색을 파악하고자 하였다. 역 분석 결과, 하류로 갈수록 화강암과 편마암 역이 공급되면서 원마도와 편평도가 증감을 반복하는 불규칙한 변화 경향을 보였다. 모래의 입도 변화는 전체적으로 중·조립사의 비율이 매우 높았으나, 화강암 지대를 흐르는 지류 합류점이 편마암 지대 합류점에 비해 다소 입경이 증가하는 경향을 보였다. This study is an analysis on gravel and sand of sand-gravel bar that stretches variously in the Duchon stream basin, which is one of Hong-Cheon River(a well-developed sand-gravel bar in upstream river)’s upper stream basin. The purpose of this study was to understand the characteristic of the stream’s topographic development that variously occur in the small basin by comparing the differences between the aspects of development and the sediment of sand-gravel bar in each section and by examining the transition of sediments moving from upstream to downstream. Through the analysis on the roundness and flatness of gravel, we observed an irregular trend following the increase in supply of granite gravel and gneiss gravel as we traveled downstream. As for the aspect of change in sand’s grain size, the overall ratio of medium-coarse sand was very high, but the results showed no big difference in the change following the inflow of stream from the main stream section to the gneiss and granite zone.

The purpose of this research is to develop the materials for natural cosmetics that it is possible to use for the improvement of acne skin. For this, this research manufactured the skin lotion and pack including ethanol extract of Caesalpinia sappan which is a bioactive chemical and applied it to the female with acne skin. And then it tried to verify the effect of the lotion and pack by measuring melanin, erythema and the changes of pH value. The objects of this research were 16 women with acne skin in 20`s above KAGS Level II, and the changes of melanin, erythema and pH value on 3 sites of the cheek, forehead and chin on their faces were measured 4 times before and after applying the pack including 15% ethanol extract of Caesalpinia sappan to 8 women (Group A) and the skin lotion including 3% ethanol extract to 8 women (Group B), respectively. The experimental data was analyzed by repeated measures using SPSS version 12.0 program. The experimental results for the changes of melanin, erythema and pH value in accordance with improvement of acne vulgaris after applying the skin lotion and pack including the ethanol extract of Caesalpinia sappan were as followings. As a result of a human closed patch test about the ethanol extract of C. sappan in a stability test, erythema (-), allergy (-), edema (-), blister (-) and so on were not observed. So, it may deem that the skin lotion and pack are stable when applying them to a human body as cosmetics. Both the skin lotion and the pack including ethanol extract of C. sappan had a positive effect on melanin and pH value. Even though there was no large difference between two experimental groups, it showed that the skin lotion influences on erythema larger than the pack. In conclusion, the ethanol extract of Caesalpinia sappan is very meaningful for improvement of acne skin and it is expected that it will become good resource for developing functional cosmetics in future.

법인세율과 개방도의 변화가 법인세수에 미치는 영향에 대한 실증분석: Laffer curve를 이용하여

오수정 ( Su Jeong Oh ) 한양대학교 경제연구소 2013 경제연구 Vol.34 No.1

본 논문은 Laffer curve를 이용하여 법인세율과 법인세수의 관계를 실증분석함과 동시에 경제사회여건의 변화가 Laffer curve 곡선 내 적정세율에 어떠한 영향을 미치는지 살펴보고자 하였다. 분석기간 내의 OECD국가의 세수입 중 법인세수가 차지하는 비중을 비교해 보면, 개인소득세의 세수가 차지하는 비율은 감소하고 있으나 법인세수가 차지하는 비율은 증가하는 추세를 보였다. 법인세율을 인하함에도 세수가 증가하는 이러한 현상은 세율인하라는 변수 이외에 경제사회여건의 변화가 법인세수 증가에 영향을 미치고 있음을 간접적으로 나타내는 근거라 할 수 있다. 이러한 배경지식을 바탕으로 분석한 결과, 예상한 바와 부합함과 동시에 법인세율과 법인세수는양의 관계를 보였으나 경제가 성장할수록 그 상관관계는 약화됨을 보였다. 또한 Laffer curve내적정세율의 이동경로가 하방하고 감소되며 동시에 세율에 대한 기울기가 점점 가팔라짐을 확인하였다. 이는 국가의 개방도가 높을수록 그리고 자본의 이동성이 높아짐에 기인하며 이러한 현상은 계속적으로 지속될 것으로 판단된다. 따라서, 경제성장 및 개방에 따라 법인세의 비중을 낮추는 OECD국가들의 조세정책은 바람직하다는 정책적 함의를 도출하였다. This paper examines the effect on corporate tax revenue from changes of corporate tax rate and openness using Laffer curve in OECD countries over the time period 1981-2009. Corporate tax rates among OECD countries have been declining steadily while corporate tax revenue increasing speedly. This is because the change of socioeconomic such as increasing the amount of trade in GDP, decreasing unemployment rate. Moreover, OECD countries are achieving a high level of economic growth since mid 1980s To consider this variation, first hypothesis is the relation between corporate tax and revenue and explore optimal tax rate in Laffer curve. Second hypothesis is the empirical analysis what the relation between corporate tax revenue and tax rate can be changed by economic growth and openness. Empirical results indicate a strong statistical evidence of Laffer curve between tax rates and revenues similar to Clausing(2007), implying a revenue maximizing corporate tax rate of 30% for the whole sample. According to analysis, it is a positive relationship between corporate tax rate and revenue. however this relation is becoming weak as the economy grew and the amount of trade in GDP increased. Also, it is found that the optimal tax rate on Laffer curve is down and a slope is steeper. As long as time goes, economies are integrated with the world and this phenomenon on this paper would be last. Consequently, it draw a policy implication that the tax policy selected by OECD countries what cut the corporate tax rate according to economic growth and increasing openness seems to be desirable.
