Objectives : This study was designed to investigate the association between the dopamine D2 receptor (DRD2) genetic polymorphism [TaqIB (rs17294542) and TaqID (rs1800498)] and patients with schizophrenia. Methods : TaqIB (rs17294542) and TaqID (rs1800498) polymorphism of the DRD2 gene were typed in 100 patients with schizophrenia and 109 normal controls. Results : There were no statistical differences in genotype and allele distribution of TaqIB (rs17294542) and TaqID (rs1800498) genetic polymorphism between patients with schizophrenia and normal controls. Conclusions : These results suggest that the TaqIB (rs17294542) and TaqID (rs1800498) polymorphisms of the DRD2 gene may not be associated with schizophrenia in the Korean population.

현금흐름할인모형에 따르면 기업가치는 미래현금흐름의 크기, 시기, 불확실성에 따라서 달라진다. 투자자 및 채권자들이 기업의 자원을 제공할지 여부를 결정할 때 해당기업의 내재가치를 알고 싶어한다. 그러므로 회계정보는 기업내재가치 추정에 필요한 미래현금흐름에 관한 예측가치를 제공하여야 한다. 또한 자산은 미래현금 창출능력이 있다. 현금흐름은 당기순이익의 구성요소로서 현금흐름 추정하기 위해서 이익예측이 우선되어야 한다. 따라서 자산이 미래이익을 창출할 능력을 알아보기 위해 자산수익률을 단순차원과 변화차원으로 분해하여 고찰하여 보았다. 재무제표분석 교재는 재무제표분석을 위해 자산수익률을 자산회전율과 매출액이익률로 분해하여 볼 것을 제안한다. 이런 기법의 탁월성에도 불구하고, 시계열적 예측에 대한 이 기법의 유용성을 증명하는 연구가 없다. 본 논문은 당기 자산수익률을 당기 자산회전율과 당기 매출액이익률로 분해하는 것이 차기 자산수익률 변동에 대한 추가적인 예측정보는 주지 않지만, 당기 자산수익률의 변동을 당기 자산회전율의 변동과 당기 매출액이익률의 변동으로 분해하는 것이 차기의 자산수익률 변동을 예측하는데 보다 유용하다는 것을 가정하여 실증분석하였으나, 통계적인 유의성이 낮은 것으로 나타났다. According to discounted cash flow model, enterprise value can vary based on future cash flows’ volume, time, and uncertainty. Investors and creditors seek for intrinsic value from a company in deciding whether to provide company resources or not. Accordingly, the account report should provide expected value of future cash flows required for estimating intrinsic value. Given that the cash flow is the component of net income, expected revenue should be prioritized to estimate the cash flow. Thus, in order to examine the ability of one’s assets can generate future profits, the return on assets were divided into simple and changeable dimensions. The financial statement analysis textbook suggests that asset return should be broken down into asset turnover and sales margin. Despite the excellence of the technique, there is no research demonstrating the usefulness of this technique for time-series prediction. This paper may not provide additional forecasting information on future asset return changes by decomposing the current asset return into asset turnover and current sales margin, it is assumed that decomposing changes in current asset return into changes in asset turnover and changes in current turnover are more useful for predicting future changes in asset returns. Empirical analysis showed that the statistical significance was low.

The purpose of this study was to measure and analyze the residual particles in the epitaxial growth chamber that can affect the process and the particles generated during the PM(preventive maintenance), which is the process of inspecting and replacing equipment parts. First, we devised a method using an ELPI(electric low pressure impactor) that can conduct real-time measurement of particle number, mass concentration and enable further analysis of chemical component by collecting the particles on the impactor substrates. Based on the result, it was confirmed that there are few particles in chamber before preventive maintenance and it is possible that amount of particles were generated or flowed from outside during the preventive maintenance work. Additionally, the components of the collected particles were analyzed through SEM-EDS analysis.
