?康과 向秀의 養生 논변

이진용 한국도교문화학회 2005 道敎文化硏究 Vol.22 No.-

혜강과 향수의 철학체계는 위진현학의 주된 흐름을 서로 다른 입장에서 수용한다. 양생논변은 바로 인간의 생명, 본성 및 이상적 경계에 대한 그들의 상이한 이론을 중심으로 전개된다. 양자의 관점은 인간 본성의 자연스러운 욕구를 인정하는 동시에 이를 적절히 제어해야 한다는 점에서 일치한다. 그러나 혜강이 인간의 본능적 욕구만을 인정한 반면 향수는 일체 욕구와 정감을 긍정하고, 구체적 욕구의 절제 방식과 양생의 방법에서도 입장을 달리한다. 이러한 인간본성에 대한 상이한 입장 차이는 위진현학의 주제를 반영한다. 자연과 명교의 관계 문제에서 혜강은 자연을 위주로 하는 체계를 세운 반면, 향수는 양자를 동등하게 합일하려는 입장에 섰다. 혜강은 일체의 인간의 자연스러운 본성을 해치는 욕구를 부정하나, 향수는 사회라는 테두리 안에서 인간의 욕구와 가치추구를 긍정한다. 또한 혜강은 ‘내성’의 중요성을 강조하고, 향수는 ‘외왕’의 정신을 ‘내성’과 동일시한다. 따라서 양자의 논변은 양생을 통해 위진시기의 시대정신을 새로운 각도에서 반영하는 중요한 자료라 할 수 있다.

Objective : This experimental study was performed to examine the anti-allergic infiammatory effects of Mori Folium. Method : Macrophage 264.7 cells were pretreated for 1hour with Sangyup. After pretreatment, macrophage were incubated with lipopolysaccharide(LPS) $100ng/m{\ell}$ 12h and media collected and $TNF-{\alpha}$, $IL-1{\beta}$, IL-6, IL-10 concentrations in supernatants were measured each by Enzyme linked immuno-sorbent assay. Sangyup were used $1mg/m{\ell}$, $500{\mu}g/m{\ell}$, $250{\mu}g/m{\ell}$, $100{\mu}g/m{\ell}$, $50{\mu}g/m{\ell}$. Hydrocortisones were used $10^{-4}M,\;10^{-5}M,\;10^{-6}M,\;10^{-6}M,\;10^{-6}M$. Results : Macrophage 264.7 cells were pretreated with Hydrocortisones and Sangyup. After pretreatment, macrophage were incubated with lipopolysaccharide(LPS). To investigate the anti-inflammatory effect of Sangyup, we measured the amount of cytokines, and the results are as follows; 1.

Combined performance of pumping and tracer tests: A case study

이진용,김정우,천정용,이명재,이강근 한국지질과학협의회 2003 Geosciences Journal Vol.7 No.3

A combined pumping and tracer test was conductedat a highly fractured aquifer system. The hydrogeologic unitsunderlying the test site are reclamation soil, weathered rock layer,and fractured layer. The fractured layer is the main aquifer forthis site. Prior to pumping and tracer tests, slug tests were con-ducted at four test wells. The test data revealed existence of a lowpermeability zone near wel OB-1. Generally the estimated hydraulicconductivities are in the order of 10-4 cm/sec. A pumping test witha discharge rate of 57 m3/d was performed for 1,230 min. Thepumping test data analysis yielded coherent hydraulic conductiv-ity values with those of the slug tests. However, the separate analysisfor each monitoring wel based on conventional analytical solutionswith highly strict boundary conditions and homogeneity assump-tion cannot efficiently show the potential existence of the low per-meability zone. During the pumping test, when the water levels ofthe pumping and monitoring wells are stabilized, a convergent radialtracer test was conducted. From the observed tracer concentration,a longitudinal dispersivity of 0.3 m was obtained, which is wel con-sistent with the values in the prominent literature considering thetest scale. This study excellently demonstrated a method complet-ing a combined pumping and tracer test at one time. A combined pumping and tracer test was conducted at a highly fractured aquifer system.

Objective : This experimental study was designed to determine the effects of BPT on obesity in vivo and in vitro. Methods : in vitro, BPTn extracts of various concentration(50, 100, 200 ${\mu}g/m{\ell}$) were added in 3T3-L1 cell. Adipocyte differentiation was measured by Oil Red O staining and Morphological examination. The expression of $C/EBP{\alpha}$ and $PPAR{\gamma}$ receptor was measured by western blot assay and RT-PCR in vivo, Rats were orally administered BPT daily for consecutive four weeks before poloxamer-407 induced hyperlipidemic state. The rats were sacrificed 24 hrs later for poloxamer-407 treated and then serum triglyceride, total cholesterol were measured ; Rats were orally administered BPT daily for consecutive four weeks before triton WR-1339 induced hyperlipidemic state. The rats were sacrificed 40 hrs later for triton WR-1339 treated and then serum triglyceride, total cholesterol were measured ; Rats with obesity were induced by the high fat-diet for six weeks and then serum triglyceride, total cholesterol, LDL-cholesterol, triglyceride, HDL-cholesterol, hydroxy radical, superoxide dismuatse activity were measured. Results : In vitro, The 3T3-L1 cells' differentiation was significantly decreased by BPT. The expression of $C/EBP{\alpha}$ and $C/EBP{\beta}$ was decreased by BPT. In vivo, BPT significantly reduced serum triglyceride, total cholesterol contents in poloxamer-407 treated rat. BPT significantly reduced serum triglyceride contents in Triton WR-1339 treated rat. Total cholesterol also reduced but did not show a significant change. BPT significantly reduced body weight gain of rat and adipose tissue mass of rats and serum triglyceride, LDL-cholesterol contents and significantly increased HDL-cholesterol, HTR(HDL-cholesterol/Total-cholesterol) in rats with obesity induced by the high fat-diet. BPT reduced blood lipid peroxide, hydroxy radical and increased superoxide dismuatse(SOD) activity.

폴리머가 프리믹스 타입의 보수용 모르타르의 성질에 미치는 영향

송형수,이진용,민창식 한국구조물진단유지관리공학회 2006 한국구조물진단유지관리공학회 논문집 Vol.10 No.4

현재, 폴리머는 보수용 모르타르의 혼화재료로 주로 사용되고 있으며, 이러한 보수용 모르타르에는 폴리머 이외에 각종 혼화재료가 첨가되어 있다. 본 연구에서는 폴리머의 배합비율에 따라 보수용 모르타르에 미치는 영향과 동일한 EVA계 폴리머가 제조사가 다른 제품에 따라 미치는 영향을 비교하고자 모르타르의 굳기 전 특성 및 역학적 특성에 대하여 시험을 통하여 분석하였다. 시험결과 보수용 모르타르에 폴리머의 배합비율이 증가될수록 역학적 특성(압축강도, 휨 강도, 부착강도)이 개선되었으며, 또한 건조수축도 증가하였다. Recently, the polymer is used as an admixture in the repair mortar, which contains various admixtures and mineral admixtures. In this study, the fresh and mechanical properties of repair mortar influenced by the types of polymers(classified as E.V.A.) and the range of polymer ratio were investigated. It was found that with increasing the ratio of polymer, mechanical properties(compressive strength, flexural strength, adhesive strength) of repair mortar is improved and drying shrinkage is increased.

$Na_2SO_4$가 시멘트-플라이애쉬 페이스트 및 콘크리트 강도에 미치는 영향

이진용,배성용,송종택,Lee, Chin-Yong,Bae, Sung-Yong,Song, Jong-Taek 한국콘크리트학회 1999 콘크리트학회지 Vol.11 No.2

플라이애쉬 대체량에 따른 변화, 양생방법이 미치는 영향 그리고 조기강도를 높이기 위해 첨가된 화학 혼화제가 시멘트-플라이애쉬 페이스트의 특징 및 콘크리트 강도에 미치는 영향을 알아보았다. 시멘트-플라이애쉬 페이스트의 압축강도는 시멘트로만 만들어진 페이스트보다 낮았으며, 플라이애쉬의 대체량이 증가할수록 강도차이가 증가하였다. 그러나 증기양생시 시멘트-플라이애쉬 페이스트는 수중양생시보다 압축강도가 증가하였으며, 특히 조기강도가 크게 향상되었다. 조기강도 증진을 목적으로 혼입한 활성화제($Na_2SO_4$)의 첨가는 시멘트-플라이애쉬 페이스트 조기강도를 증진시켰으며, 또한 $Na_2SO_4$와 플라이애쉬를 30% 함유한 플라이애쉬 콘크리트의 강도도 월등히 향상되었다. It was investigated to evaluate the characteristics of cement-flyash paste which was affected the replacement level, curing method and chemical admixtures. The strength of cement-flyash paste was lower than that of cement paste only and the differences increased with increasing the replacement level. However, in steam curing, the strength of cement-flyash pastes was improved and specially, the early strength was effectively increased. The inclusion of $Na_2SO_4$ increased the early strength of cement-flyash paste. In addition, the strength of concrete including 30% of fly ash and $Na_2SO_4$ has improved and obtained the highest strength compared to other concrete mixes.
