"난경(難經)"의 오유혈(五兪穴) 이론(理論)이 가장 많이 제기되는 문제는 '육십팔난(六十八難)'의 오유혈(五兪穴)의 주치작용(主治作用)이다. "영추 본수편(靈樞 本輸篇)"에서는 다만 오유혈(五兪穴)의 명칭과 위치에 대해서 소개하고 있지, 계통적인 주치에 대한 설명이 없고, '육십팔난(六十八難)'에서 명확히 5가지 종류의 질병에 대해서 귀납(歸納)하고 오유혈(五兪穴)이 주관하는 병증(病證)을 분별하여 후세의 모범이 되고 있다. 그러나 "난경(難經)"에서 오유혈(五兪穴)에 대해서 물이 흐르는 형상을 비유하여 사지(四肢)에서 체간(體幹)으로 향하는 노선으로 설명하고 있는데, 이는 "내경(內經)"의 십이경맥(十二經脈)이 여환무단(如環無端)하는 체계와 전혀 부합하지 않아서 학문과 임상에 있어서 지금까지도 혼란을 야기하고 있다. 그동안 "갑골문자(甲骨文字)"를 해독하기 위한 심도 있고 다양한 연구가 진행된 결과 고문자(古文字)의 해독(解讀)잘못된 계산식을 위한 공구서(工具書)들이 많이 개발되었는데, 본 논문은 그러한 고문자(古文字) 해독(解讀)의 연구방법(硏究方法)을 통해 "난경(難經)"의 오유혈(五兪穴) 이론(理論)의 난제(難題)를 해결하고자 한 것이다. 예를 들어 정형수경합(井滎輸經合)에 대해서 "난경(難經)"의 '육십팔난(六十八難)'에서 "소출위정(所出爲井), 소류위형(所流爲滎), 소주위유(所注爲兪), 소행위경(所行爲經), 소입위합(所入位合)"이라고 설명한 그 것 중에서 출(出), 류(流), 주(注), 행(行), 입(入)과 정(井), 형(滎), 유(兪), 경(經), 합(合)의 글자를 고문자(古文字) 해독(解讀)의 측면에서 재해석함으로써 이를 의학적(醫學的)으로 활용할 수 있도록 그 실마리를 제공하였다.

Korea and China should come up with a mutually beneficial FTA proposal at an early date and thus lead the way towards the FTA. An FTA with China is a key issue of economic cooperation in order to confront soaring Chinese competitiveness in international markets. The purpose of this research paper is to analyze the overall Busan regional economy impacts of the Korea-China FTA. We analyzed the quantitative effects of an FTA by using microeconomic concept. The Korea-China FTA will have positive effects on the overall industry in Busan. Therefore, Busan regional industries exports and imports are expected to grow. Busan is worried the deal would pave the way for imports of cheap Chinese agricultural products, hurting the nation's already fragile agricultural sector. In contrast, Busan's manufacturing sector is expected to see its surplus rise. In sum, we think the FTA will bring benefit to the whole industry in Busan Regional economy because it accelerates development of the industries by trade and investment along with comparative advantage.

Sulfate adsorption in forest soils is a process of sulfur dynamics playing an important role in plant uptake, cation movement, acid neutralization capacity and so on. The relationship between sulfate adsorption and some physicochemical properties of four forest soils was investigated. Extractable sulfate contents and sulfate adsorption capacity (SAC) in the forest soils varied much among study sites. Extractable sulfate contents were more in sub-surface soils with lower organic matter and greater Al and Fe oxides than in surface soils. The average contents of $Al_d$ and $Fe_d$ in the sub-surface soils were 8.49 and $12.45g\;kg^{-1}$, respectively. Soil pH, cation exchange capacity and clay content were positively correlated with the extractable sulfate contents and SAC. Organic carbon content, however, was negatively correlated with the extractable sulfate contents, implying the competitive adsorption of sulfate with soil organic matter. Considerably significant correlation was found between inorganic + amorphous Al and Fe oxides and the sulfate adsorption, but crystalline Al and other fractions of Fe oxide showed no correlation. Relatively close relationship between the adsorbed sulfates and soil pH, cation exchange capacity, or amorphous Al oxides indicates that the accelerated soil acidification may substantially reduce the potential for sulfate adsorption contributing to sulfur flux in forest ecosystems.
