God for Catholicism : 캐도��의 신관
Thomas 이화여자대학교 기독교학회 1966 포도나무 Vol.- No.3
Thomas's는 다음과 같이 신의 존재를 증명한다. 신의 존재를 다음의 다섯가지 방법으로 증명할 수 있다고 답변한다. 첫번이고 가장 명백한 방법은 "운동(motion)"에 관한 토론이다. 무엇이 움직이고 있다는 것은 우리가 분명히 명백하게 느낄 수 없다. 움직이는 것은 모두 다른 사물에 의해 움직여 지고 있는 것이다. 왜냐하면 사물이 어떤 것을 향해 움직이고 있는 잠재력을 가지고 있기 전에는 움직일 수가 없기 때문이다. 즉 행동을 하고 있으므로 움직이는 것이다.
Incipient Cavitation in a Bulb Turbine: Model Test and CFD Calculation
Necker, Jorg,Aschenbrenner, Thomas Korean Society for Fluid machinery 2011 International journal of fluid machinery and syste Vol.4 No.1
For a certain operating point of a horizontal shaft bulb turbine (i.e. volume flow, net head, blade angle, guide vane angle) the efficiency for different pressure levels (i.e. different Thoma-coefficient ${\sigma}$) is calculated using a commercial Computational Fluid Dynamics (CFD-)-code including two-phase flow and a cavitation model. The results are compared with experimental results achieved at a closed loop test rig for model turbines. The comparison of the experimentally and numerically obtained efficiency and the visual impression of the cavitation show a good agreement. Especially the drop in efficiency is calculated with satisfying accuracy. This drop in efficiency in combination with the visual impression is of high practical importance since it contributes to determine the admissible cavitation in a bulb-turbine. It is seen that the incipient cavitation in Kaplan type turbines has no major importance in determing this admissible amount of cavitation.
An Economic Evaluation of the European Union’s 2030 Climate Policy Plan
Thomas R. Sadler(Thomas R. Sadler ) People&Global Business Association 2023 Global Business and Finance Review Vol.28 No.1
Purpose: The purpose of the study is to evaluate the European Union’s “Fit for 55” plan, announced in 2021, which intends to meet a 2030 goal of reducing carbon emissions by 55 percent from 1990 levels. Design/methodology/approach: An analytical model is used to assess the impact of the EU environmental policies, including the carbon border tax, emissions trading system, energy efficiency, and emission standards. Findings: The study finds that the environmental policies achieve different policy criteria, including cost minimization, equalization of marginal abatement cost, minimization of general equilibrium cost, political feasibility, and minimization of inequitable impacts across income groups. But no single policy instrument is necessarily superior to the others. The paper finds that a revenue-neutral carbon border tax and an emissions trading system with auctioned permits satisfy the most evaluation criteria. Research limitations/implications: For the purpose of simplification, the model ignores dynamic extensions. That is, the adjustments of businesses to policy measures and the effects on emissions are beyond the scope of this analysis. Originality/value: The study develops a model that evaluates the European Union’s environmental policies in a unifying perspective, assessing the tradeoffs of policy design.

Prospects for Canada’s Federalism in the 21st Century
Thomas R. Klassen(Thomas R. Klassen ) 한국캐나다학회 2007 Asia-Pacific Journal of Canadian Studies (APJCS) Vol.13 No.1
When Canada was created in 1867 it was a union of essentially equal provinces, with federal powers balanced between the House of Commons and the Senate. The new country was closely tied to Great Britain, and Aboriginal peoples were excluded from the governance of Canada. Developments in the past 140 years including the increase in the scope of provincial activities call for reforms to Canada’s governance structures especially with regard to: 1) the head of state; 2) the Senate; 3) the Atlantic provinces; 4) the role of Aboriginal peoples; and 5) education policy. Reforms in these areas, including a “made-in-Canada” head of state, a transformation of the Senate, a review of how the Atlantic provinces might better collaborate, the inclusion of Aboriginal peoples in governance fora, and a greater federal role in education policy will prepare Canada for the challenge and opportunities of the 21st century.
폐기물 소각 잔류물의 매립 : 새로운 접근 방법에 대해
( Thomas H. Christensen ),( Thomas Astrup ),( Zuansi Cai ),( Dezhen Chen ) 한국폐기물자원순환학회 2002 APLAS Vol.2002 No.2
폐기물 소각시설로부터의 잔류물은 대표적으로 바닥재와 비산재를 포함한 대기오염방지시설에서 나오는 잔류물이다. 이러한 재로부터 상당량의 중금속과 염이 용출되며, 다양한 용출실험을 통하여 비산재 및 바닥재의 매립 규제를 위한 기준이 제안 되어왔다. 그러나 실제 처분하는 현장과 동일하게 정보를 제공 및 매립하기 전에 잔류물들의 전처리의 이익평가를 하기 위해서 용출실험은 주의 깊게 선택 되어야만 한다. 본 논문은 매립된 잔류물에서의 pH-변화 및 Cr 용출능에 대한 용출실험의 영향과 FeSO<sub>4</sub> 를 이용한 전처리의 효과를 서술하였다. Residues from waste incineration are bottom ashes and air-pollution-control (APC) residues including fly ashes. The leaching of heavy metals and salts from the ashes is substantial and a wide spectrum of leaching tests and corresponding criteria have been introduced to regulate the landfilling of the ashes. Leaching test, however, must be selected carefully to provide information relevant for the actual disposal scenario and for evaluating the benefits of pre-treating the residues prior to landfilling. This paper describes research at the Technical University of Denmark addressing some of these issues focusing on pH-development in landfilled residues, effects of leaching test conditions on Cr leaching and effects of pre-treatment with FeSO<sub>4</sub>.
