1. 五運六氣學根干皇帝內經素問的運氣篇. 五運六氣學由木火土金水五運和風寒暑濕燥火六氣構成. 對傷寒論, 金元四大家醫論, 直至東醫寶鑑, 在診斷和治療人體疾病方面, 作爲核心原理所被應用. 僅用五運六氣, 學說形成醫學理論的學派有朝鮮時代尹東里先生的草窓訣, 日帝時代趙元熙先生的五運六氣醫學賣鑑等. 2. 運氣學的有限性在干把天地自然的普遍變化原理適用干人體, 使其一般化, 而疏忽了人間自身體質的特性. 3. 四象醫學是19世紀末李濟馬先生所創, 幷通過東醫壽世保元發表干世的體質醫學. 李濟馬先生的東醫壽世保元的內容爲人體具有固有的體質特性和性情的差異, 因此, 應根據適些來診斷和治療疾病. 從飮食到養生, 以體質來分類. 根據個人的體質來調節相應的獨特的理論體系. 4. 以前內經的運氣學以天地自然的原理爲中心內掌據人體, 而疏忽了人體自身爲主體的原理, 因此具有一定的有限性. 李濟馬先生的東醫壽世保元也一樣, 以人體爲中心的原理來掌갈人而疏忽了天地自然的變化原理, 卽, 四象醫學的問題재干重視人體自身的體質特性, 而疏忽了天地自然的變化原理. 5. 五運六氣學是硏究天地原理的理論體系, 四象醫學是以人體爲主, 來硏究人體的體質醫學. 因此, 根據天地人相應的原理, 以五運六氣掌握天地的狀態, 用四象醫學內掌握人體自身的特性, 把這兩者相互融合, 就會體現出明願的人形象. 所以, 根據天地人相應的原理, 韓醫學的基本原理可以通過以天地自然爲原理的 五運六氣學和以人體爲原理的四象醫學的硏究, 應綜合天地人原理, 將其適用干韓醫學. 6. 五運六氣和四象醫學對人體的定義, 期待以後有更多角度的硏究
3.5% NaCl 水溶液의 溫度變化가 SS41鋼의 腐蝕疲勞破壞에 미치는 影響
吳世旭,姜鎬珉,金廣泳,都映旼 東亞大學校 海洋資源硏究所 1988 硏究論文集 Vol.1 No.1
Corrosion fatigue test was performed under rotary bending in 3.5% NaCl aqueous solution having a temperature from 278°K to 318°K in order to investigate the effects of aqueous solution temperature on the corrosion fatigue fracture of SS41 steel. Fatigue life was remarkebly decreased with an increase in aqueous solution temperature. Fatigue life reductions for high stress level were somewhat smaller than those for low stress level, but S-N curves were nearly become parallel lines. Corrosion fatigue crack propagations were accelerated with an increase in aqueous solution temperature. The corrosion fatigue result at aqueous solution temperature of 303°K was showed about the same behaviour as those at 318°K in both S-N curve and da/dN-ΔK curve, which was considered as consequence of limiting diffusion current density(??). As aqueous solution temperature was increased, corrosion was gradually activated in view of fractured surface.

『在『黃帝內經』中「陰陽應象大論」與「五運行大論」所言及的"東方生風 風生木 木生酸 酸生肝", 是說明關於肝發生的文章. 肝臧血是肝之發生學特性中屬酸生肝, 卽從飮食所供應的陰形物質轉化爲陽氣的生理現象, 肝的貯藏血液功能可視爲水穀之氣的酸味的作用. 肝的發生論說明天地之調合作用是人類的生成根本因素. 說明在天之六氣和地之五行中介入五味, 旣可生成人類. 從而再次可以確認關于人類發生之"天地合氣命曰人"的含意. 肝的發生原理說明了肝是通過無極, 太極, 陰陽及所生成的六氣和五行相組合而生成的, 這一點確認了此爲陽化氣, 陰成形的過程, 是說明宇宙萬物和人類生成的根本原理.
페라이트-마르텐사이트 이상조직강의 피로파괴거동에 미치는 노치효과
도영민 한국안전학회 2003 한국안전학회지 Vol.18 No.3
For the tensile tests of the F.E.M., microvoids are created by the boundary separation process at the martensite boundary or neighborhood and at inclusions within the ferrite, to grow to the ductile dimple fracture. For the case of the M.E.F., microvoids created at the discontinuities of the martensite phase which exists at the grain boundary of the primary ferrite are grown to coalescence with the cleavage cracks induced at the interior of the ferrite, which as a result show the discontinuous brittle fracture behavior. In spite of their similar tensile strengths, the fatigue limit and the notch sensitivity of the M.E.F. is superior to those of the F.E.M. The M.E.F. is much more insensitive to notch than F.E.M. from the stress concentration factor( a). Key Words : Martensite Encapsulated islands of Ferrite(M.E.F.), Ferrite Encapsulated islands of Martensite(F.E.M), notch, stress concentration factor, fatigue strength, fatigue limit
SS41 강의 F. E. M. 복합조직강에서 노치변화가 부식피로파괴에 미치는 영향

The rotated bending fatigue test was conducted in air and in 3.5% NaCl salt solution to investigate the fatigue fracture behaviour of raw material and F.E.M dual phase steel made from raw material(SS41) by a suitable heat treatment. This study has the initial microcrack creation of material by tensile test with that by fatigue test. And the rotated bending test of cantilever type under the condition of 3.5% NaCl salt solution and air has investigated the corrosion fatigue fracture behaviour with the variation of stress concentration factor determined by each of notch shapes. The initial microcrack have been developed in fragile grainboundary with general corrosion occurring in raw material ; in the pits built up by corrosion in F.E.M. dual phase steel because pits bring out stress concentration. It is small that the degree of decrease in corrosion fatigue life for F.E.M. dual phase steel compared with raw material because the notch sensitivity of F.E.M. dual phase steel is lower than raw material in reason of characteristics with two-phase construction.

In this numerical study, characteristics of swirl generation by the fan and selection of the location of the fan was studied theoretically by the modified TEACH code. The governing equation for the system are solved by means of the three dimensional version of the SIMPLE method and STAGGERED grid. From the present results, the optimal position of the fan is 0.625(h/H).
