        Translation Universals: Do They Exist?

        Eddie Ronowicz 한국외국어대학교 통번역연구소 2009 통번역학연구 Vol.13 No.1

        본 연구는 사고발화법(TAP, Think-Aloud Protocols), 원천언어와 번역 코퍼스연구, 병행텍스트, 설문조사 등 최근 번역학 연구에서 주로 활용되고 있는 일련의 연구방법론을 비판적인 시각에서 검토하고자 한다. 현재 이론으로서의 번역학 연구는 가설을 수립하고 실험을 진행하는 연역적 연구보다는 번역 현상을 귀납적으로 파악하는 실증적 연구 단계에 있다. 그리고 지금까지 나온 보편 이론에 대한 규명은 가능할 수도 있지만 이론과 가설을 검증하기 위해 필요한 연구방법론이 제대로 확립되어 있지 않은 상황이다. 이에 대해 본 연구에서는 현재의 연구 상황을 감안할 때 번역의 보편 이론 찾기는 어떤 측면에서는 비효율적일 수도 있음을 지적하면서 번역텍스트의 현상을 규명하는 데 번역학 연구의 초점을 맞추는 것이 보다 효율적임을 주장하고자 한다.

        A SENSITIVITY STUDY OF THE DISTORTED INLET FLOW IN AXIAL TURBOMACHINERY WITH NOVEL INTEGRAL SCHEME

        Eddie Yin-Kwee Ng,Ningyu Liu,Hong Ngiap Lim,Daniel Tan 한국전산유체공학회 2005 한국전산유체공학회지 Vol.10 No.1

        For proper installation, operation and performance of axial flow jet engines in aircrafts, the impacts and effects of inlet flow distortion in axial compressors have to be understood. Inlet distortion conditions may cause component-mismatch and instability problems known as rotating stall, and severe oscillations of mass flow rate called surge or a combination of both. Typical effects of this phenomenon include stresses and wear on the compressor blading, destruction of entire jet engines due to the failure of airfoil and mechanical failure or interruption of the combustion process. Therefore, it is important to study inlet flow distortion and its propagation effects to minimize and hence to prevent the occurrence of such calamity.<br/> The current novel integral method with parametric analysis signifies its validity to this field of research and offers much potential for further improvements. The present effort further indicates that this simple method may be flourishing in the problems of strongly distorted flow and propagating stall in axial compressor. It is therefore believe that using a more realistic and flexible velocity and pressure profiles could develop this approach further.

        Effect of Scoria on Various Specific Aspects of Lightweight Concrete

        Eddie Franck Rajaonarison,Alexandre Gacoin,Roger Randrianja,Velomanantsoa Gabriely Ranaivo,Bam Haja Nirina Razafindrabe 한국콘크리트학회 2017 International Journal of Concrete Structures and M Vol.11 No.3

        Experimental research on the technical characteristics of lightweight concretes incorporating scoria was conducted. The objective of this research is to investigate the feasibility and effectiveness of the use of scoria, in lightweight concretes. Coarse scoria of 5/10 and 10/20 mm were used. A portion of the aggregate mixtures had an average particle size ≤100 ㎛. Scorias are often used as the constituents of structural concrete and insulating materials. The usability of the concretes tested in this study broadens as the porosity of the mixtures decreased and the cement dosage increased. According to the cement dosage and frequency types, the absorption coefficients of concretes ranged from 0.14 to 0.47. A compressive strength of 19 MPa corresponded to a density of 1800 kg/m³; compressive strengths from 10 to 18 MPa mapped to densities ranging from 1300 to 1700 kg/m³. The thermal conductivity of mixed concretes without scoria reached a maximum value of 0.268 W/m K. The thermal conductivity values of the concretes mixed without sand were below 0.403 W/m K. As sand content increased, the conductivity evolved from 0.565 to 0.657 W/m K. Freeze-thaw stability tests were conducted for 400 cycles or until specimens deteriorated. The experimental results helped in determining the optimum mixing conditions for the inclusion of scoria in cement to produce lightweight concretes.

        A bioassay for natural insect repellents

        Eddie Hang Chio,En-Cheng Yang 한국응용곤충학회 2008 Journal of Asia-Pacific Entomology Vol.11 No.4

        A practical bioassay for natural product insect repellents was developed and validated. The Asian tiger mosquito (Aedes albopictus) was used in this study. Djulis (Chenopodium spp.), an indigenous plant from Taiwan, provided better insect repellency than neem tree (Azadirachta indica) oil, a well-known insect repellent. The % repellency of each test material was converted to 50% effective dosage (ED50) by probit analysis for better comparison between test materials. The ED50 for insect repellency in descending order was djulis leave extract (0.532%), neem oil (0.579%); djulis seed extract (0.930%) and sea lily (Crinoid spp.) (1.022%).

        Application of Image Analysis for Precise, Noninvasive Measurement of Plant Culture Growth

        James, Eddie,Yoo, In Sang,Lee, James M. 한국화학공학회 2004 Korean Journal of Chemical Engineering Vol.21 No.1

        Accurately measuring the growth of solid cultures is important for evaluating regrowth following low temperature storage, cell screening on selective media, or the suitability of different media formulation. However, current procedures are inadequate to provide precise, quantitative data non-invasively. This paper describes the development of an image analysis technique to provide quantitative growth data for callus cultures. Various properties obtained from image analysis, such as area, perimeter, diameter, and integrated density valued, were correlated with the observed mass of plant callus. Based on this data, a predictive linear model was developed. The image analysis method was used to estimate cell mass as a function of various media components and growth conditions. This work demonstrates that image analysis is a flexible and useful tool for monitoring cultures.

        Comparing Plant Species Diversity of Mountainous Deserts - Successes and Pitfalls

        Van Etten, Eddie J.B. The Ecological Society of Korea 2004 Journal of Ecology and Environment Vol.27 No.2

        An extensive study of the vegetation characteristics of the Hamersley Ranges, a mountainous desert area of north-west Australia, facilitated the comparison of plant species diversity measures with mountainous deserts of other parts of the world. Alpha diversity was defined as the number of species co-existing at local scales and was found to average 18 species per 0.1 ha for the Hamersley Ranges. This was found to be similar to seven other mountainous deserts in North and South America, and southern Africa. Variation in alpha diversity between these deserts was found to considerably lower than within deserts, suggesting that local processes control species richness at local scales. Beta diversity, defined here as turnover in species composition at various spatial scales, can be measured in many ways. For the Hamersley Ranges, Wilson's β ranged from 1.2 to 1.6 for five sites along a topographic gradient, whereas Whittaker's β between different plant communities was found to average 0.93. Comparable data was not found for other desert areas, but comparisons to non-desert areas suggest beta diversity within landscapes is relatively high and is likely to reflect the considerable landform heterogeneity of the Hamersley Ranges. 55∼70% of species were shared between different landscapes of the Hamersley Ranges; comparisons to other regions suggest beta diversity at this scale is relatively low. Gamma diversity, the number of species over large spatial extents, was successfully compared using regression analysis of the log-log species - area relationship. This revealed that the northern Sonoran desert has significantly less species than the Nama (inland) Karoo and Hamersley Ranges over medium spatial extents, but species numbers were similar at a regional scale. Several constraints to the valid comparison of species diversity were identified, including lack of standardisation of sampling techniques, the wide range of measures employed, general lack of published data, and the influence of the various components of spatial scale on most diversity measures. Recommendations on how to improve future comparative work are provided.
