Since the opening of this country in 1876, we had kept our own cultural orientation and this cultural orientation had been working as principle of our individual and community life. But this orientation became degraded through the colonial policy of Japan and the set-up of military government by U. S. A and U. S. S. R, and also came to be deformed after the division of the country. From these reasons, it follows that modern Korean Ethics must tend to creativly modify the cultural orientation, which we aimed since 1876, and that Korean Ethics must be based on this fact. This is the question at issue and the object of this paper, For the settlement of the question, this paper develops the following details. First, the concept of Korean Ethics is defined on the level of cultural specificity and universality, and the orientation of Korean Ethics is explaned with relation to that of Korean Culture. Second, we had considered the education of Korean Ethics dividing our modern history into the opeining the country, the colonization, the military government of two powers and the post-establishment of two Korea. Third, the value that Korean Ethics must aim is discussed with reference to man, society and nation. In conclusion, it is argued that with the succession of our cultural orientation, Korean Ethics must be established by way of national consensus, and that through the educative efforts it must be interiorized towards the members of our society.

The objective of this study is to predict the high risk group of coronary artery disease from body mass index, blood pressure, fasting blood sugar and serum lipids level using the method of discriminant analysis. Variables with significant difference between coronary artery disease group and normal group were HDS-C, LDL-C/HDL-C, LDL-C, and TG. But the acuity did not exceed 70% in any single variable. As the results of discriminant analysis, statistically significant discriminant variables were HDL-C, T-chol, FBS and TG. The discriminant equation was(Y) = -0.06759(HDL-C) + 0.01498(T-chol),+0.01923(FBS) - 0.01421(TG) + 0.5187, and the overall discriminant power using the above 4 variables was 79.3%
Effects of MWCNT Nucleating Agent on the Formation Reaction of Rigid Polyurethane Foams
( Won Sool Ahn ),( Joon Man Lee ) 한국고무학회 2015 엘라스토머 및 콤포지트 Vol.50 No.1
A study of the effects of MWCNT as a nucleating agent on the formation reactions of the rigid polyurethane foams (RPUFs) was carried out. Sample PUFs, formulated with grease-type master batch of MWCNT/surfactant, were fabricated by free-rising method. Temperature changes with time during foaming process were measured using a digital thermometer. RPUF foaming process was observed to undergo 2-step processes with temperature inflection around 60 sec after the start of reaction, and then reached slowly the max. temperature. While the max. temperature of neat PUF was measured as ca. 120oC, that of the samples with MWCNT were as higher value as ca. 130oC, and, even the time to reach that temperature was reduced by about 15 sec. Average cell size of PUF samples decreased from 185.1 for the neat PUF to 162.9 μm for the sample of 0.01 phr of MWCNT. As the result, it was considered that MWCNT in RPUF foaming process could play a roll both as a nucleating agent and as a catalyst.
