The "Sound Classification System on Floor Impact Sound Insulation Performance" is being studied in Korea. For that study, vocabularies appropriate for evaluation and reporting are needed. In this study, adequate words for evaluating floor impact sound have been extracted by reviewing the existing vocabularies and augmenting this with the results of a questionnaire prepared especially for apartment dwellers. As a result of this study, followings are suggested. 1) The heavy impact sound sources are more highly ranked than light impact ones. And the louder sound sources are the more accumulated points. 2) Highly ranked vocabularies are different for each source. 3) Floor impact sound evaluating words such as ‘Annoying’, ‘Disagreeable’, ‘Strident’, ‘Disturbed’, and ‘Dissonant’ are highly ranked. ‘Annoying’ is the word most accurately expressing the subjects' unpleasant feeling of domestic floor impact noise. 4)‘Unpleasant’, ‘Noisy’, ‘Irritating’, ‘Annoying’ are main unpleasant factors to floor impact sounds occurring in our domestic apartment houses.
한국의 잉여가치율: 1980-2011년 - ‘노동시간의 화폐적 표현’ 모형이 지니는 약점과 그 보완
정구현(Jeong Gu hyeon) 한국사회경제학회 2016 사회경제평론 Vol.29 No.2
잉여가치율 계산에 이용하는 표준적 모형 중 하나로 국민소득계정을 이용한 노동시간의 화폐적 표현 모형을 들 수 있다. 이 모형은 몇 가지 뛰어난 강점이 있지만, 결정적으로 잉여가치율을 과소평가하게 하는 약점을 지닌다. 본 연구는 이 약점의 원인을 분석하고, 마르크스의 가치론에 부합하도록 노동시간의 화폐적 표현 모형을 보완하는 것을 목적으로 한다. 또한, 보완된 모형을 바탕으로 1980년에서 2011년까지 한국의 잉여가치율을 계산할 것이다. The ‘Monetary Expression of Labor Time(MELT)’ model using National Income-and-Product Accounts(NIPA) is one of the standard methods used to calculate rate of surplus value. Although, MELT model has several important advantages, its weakness is fatal because this model underestimates the rate of surplus value. The purpose of this paper is to analyze the cause of this underestimate, and to improve the MELT model so that it corresponds to Marx's value theory. This argument will be supported by the empirical evidence, the rate of surplus value in South Korea, 1980-2011.
Pharmacokinetic and Pharmacodynamic Interaction between Metformin and (-)-Epigallocatechin-3-gallate

(-)-Epigallocatechin-3-gallate (EGCG), a major flavonoid in green tea has multiple health benefits including chemoprevention, anti-inflammatory, anti-diabetic, and anti-obesity effects. In connection with these effects, EGCG can be a candidate to help the treatment of metabolic diseases. Metformin is a widely used anti-diabetic drug regulating cellular energy homeostasis via AMP-activated protein kinase (AMPK) activation. Therefore, the combination of metformin with EGCG may have additive or synergistic effects on treatment of type 2 diabetes. Nevertheless, there is no report for the pharmacokinetic and/or pharmacodynamic interaction of EGCG with metformin. Here, we evaluated the pharmacokinetic and pharmacodynamic interaction between metformin and EGCG in rats. Pharmacokinetics parameters of metformin were measured after oral administration of metformin in rats pre-treated with EGCG (10 mg/kg) or saline for 7 days. The results showed that there is no significant difference in pharmacokinetic parameters between saline control and EGCG-treated group. In addition, the hepatic AMPK activation by metformin in EGCG-treated rats was also similar to the control. The lack of additive effects of EGCG on AMPK activation or intracellular uptake of metformin was also evaluated in cells in the presence or absence of EGCG. Treatment of HepG2 cells with EGCG inhibited the metformin-induced AMPK activation. Combined results suggested that EGCG has no effect on the pharmacokinetics of metformin but may contribute to metformin action.
『요강』에서의 ‘가치법칙의 위기’와 『자본론』에서의 ‘노동자투쟁’

Autonomist, including Negri, derive directly from "the Crisis of the Law of Value" mentioned in "Fragment on Machines" to communism "as transition". Therefore, Autonomist evaluate that Grundrisse is more important literature than Capital which does not include substance like "the Crisis of the Law of Value" as transition mediation. However, this Autonomist Reading about "Fragment on Machines", which predicates that "the Crisis of the Law of Value" already means foundation of communism itself, not just necessary condition of communism, be biased to the "politisme". This paper argue that "Workers` Struggle" is the mediation which turns condition of communism into actual foundation of it, and that what includes this implication of "Workers` Struggle" is the Capital. While the Crisis of the Law of Value creates Universal Worker limited to capitalism, Workers` Struggle becomes transition mediation, as direct representation such as "Factory Act" beyond indirect representation of relationship between labor and capital. In this perspective, it can emerge that excellence of Marx`s "the Critique of Political Economy" which expain transition to communism with dialectical relationship between labor and capital.
