        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.

        Gamete-associated flavobacteria of the oviparous Chinook salmon (Oncorhynchus tshawytscha) in lakes Michigan and Huron, North America

        Thomas P. Loch,Mohamed Faisal 한국미생물학회 2016 The journal of microbiology Vol.54 No.7

        Flavobacterial diseases, caused by multiple members of the Family Flavobacteriaceae, elicit serious losses in wild and farmed fish around the world. Flavobacteria are known to be transmitted horizontally; however, vertical transmission has been suspected but proven only for one fish-pathogenic flavobacterial species (e.g., Flavobacterium psychrophilum). Herein, we report on the isolation and molecular identification of multiple Flavobacterium and Chryseobacterium taxa from the ovarian fluid and eggs of feral Great Lakes Chinook salmon (Oncorhynchus tshawytscha). Identified egg- and ovarian fluid-associated flavobacteria were either well-known flavobacterial fish pathogens (e.g., F. psychrophilum and F. columnare), most similar to emerging fish-associated flavobacteria (e.g., F. spartansii, F. tructae, F. piscis, C. piscium, C. scophthalmum), or were distinct from all other described Chryseobacterium and Flavobacterium spp., as determined by phylogenetic analyses using neighbor-joining, Bayesian, and Maximum Likelihood methodologies. The gamete-associated flavobacteria fell into three groups (e.g., those that were recovered from the ovarian fluid but not eggs; those that were recovered from the ovarian fluid and eggs; and those that were recovered from eggs but not ovarian fluid), a portion of which were recovered from eggs that were surface disinfected with iodophor at the commonly used dose and duration for egg disinfection. Some gamete-associated flavobacteria were also found in renal, splenic, and neurological tissues. Systemic polymicrobial infections comprised of F. psychrophilum and F. columnare were also detected at nearly an 11% prevalence. This study highlights the potential role that sexual products of female Great Lakes Chinook salmon may play in the transmission of fish-associated flavobacteria.

        Free/Libre Open Source Software in Health Care: A Review

        Thomas Karopka,Holger Schmuhl,Hans Demski 대한의료정보학회 2014 Healthcare Informatics Research Vol.20 No.1

        Objectives: To assess the current state of the art and the contribution of Free/Libre Open Source Software in health care (FLOSS-HC). Methods: The review is based on a narrative review of the scientific literature as well as sources in the context of FLOSS-HC available through the Internet. All relevant available sources have been integrated into the MedFLOSS database and are freely available to the community. Results: The literature review reveals that publications about FLOSS-HC are scarce. The largest part of information about FLOSS-HC is available on dedicated websites and not in the academic literature. There are currently FLOSS alternatives available for nearly every specialty in health care. Maturity and quality varies considerably and there is little information available on the percentage of systems that are actually used in health care delivery. Conclusions: The global impact of FLOSS-HC is still very limited and no figures on the penetration and usage of FLOSS-HC are available. However, there has been a considerable growth in the last 5 to 10 years. While there where only few systems available a decade ago, in the meantime many systems got available (e.g., more than 300 in the MedFLOSS database). While FLOSS concepts play an important role in most IT related sectors (e.g., telecommunications, embedded devices) the healthcare industry is lagging behind this trend.
