Wells, John The Korean Society Of Phonetic Sciences And Speech 1989 말소리 Vol.15 No.-
다음은 창립 10주년을 맞은 대한음성학회의 초청으로 내한한 런던대학의 음성학. 언어학과 교수인 존 웰스 교수가 1987년 9월 22일에 한글학회 강당에서 열린 창립 기념식장에서 "현대 세계의 음성학"이라는 제목으로 행한 특별강연의 초록이다. 전반부는 생략하고 후반부만을 원문과 우리말로 옮겨 싣는다. It is an honour to be speaking on phonetics at the invitation of the Phonetic Society of Korea. Through the Korean Hangout script, invented in the fifteenth century at the instigation of the great King Sejong, and the work Hunminjeongeum which describes it, this country has an important place in the world history of phonetics. Phonetics is the description and analysis of pronunciation. Spoken language can be investigated at three points: in the speaker (articulatory phonetics), in the hearer (auditory phonetics), and in the physical speech signal (acoustic phonetics)... Beginners in English who are Korean mother tongue have to learn to make the sound 'f' as in "coffee", which is a voiceless labio-dental fricative, lip on upper teeth. They also have to learn to make [\theta]sound in "think", a voiceless dental fricative.

Objective The use of pediatric length-based weight estimation tapes with precalculated drug doses is advocated by major Advanced Life Support organizations, but concerns have been raised on the accuracy of these systems. The objective of this systematic review was to collect, review, evaluate, and create a synthesis of the current literature to establish whether there is high-quality evidence for use of length-based tapes in accurate drug dose administration. A further objective was to compare these tapes with other dosing aids. Methods Eligible studies were identified and analyzed if they were peer reviewed, full text articles containing original data. Studies including any form of length-based precalculated drug dosing methodology in children aged 0 to 18 years were included. Results Eighteen studies met the inclusion criteria. The most studied of the tapes was the Broselow tape in 16 studies (88.9%). When these tapes were used on their own without additional reference material, they produced a substantial number of potentially harmful dosing errors (>20% error). No tape was superior to another. Using the tapes was better than using no dosing aid but was inferior to using both comprehensive drug dosing guides and novel color-coded medication administration systems. Conclusion There was no high-quality evidence that the use of length-based tapes with precalculated drug doses leads to accurate drug dosing. However, comprehensive drug dosing systems were more effective at reducing dosing errors than were length-based tapes on their own. The confounding effect of weight estimation accuracy on drug dosing accuracy has not been sufficiently studied.

Reinterprething The History of Life From a Design Perspective
Wells, Jonathan 선문대학교 통일사상연구원 1997 통일사상 연구논총 Vol.3 No.-
Therefore, I begin by assuming that human beings are the intended outcome of the history of life. It follows that the history of life was planned from the outset to provide a temperate environment and nourishing food for us, requiring the establishment of complex, self-sustaining ecosystems. It also follows that the first human beings were born into a world already populated by human-like mammals capable of raising them from birth. This, in turn, required other animals as precursors, implying that what Darwinists regard as a contingent pattern is actually a necessary progression, at least in general outline. Like Copernicus's shift from a geocentric to a heliocentric solar system, the shift from denying to affirming design is a conceptual change with far-reaching implications for our understanding of objective reality. A design perspective accounts for at least some of the anomalies confronting Darwin's theory, and could lead to more fruitful research programmes in biology.

Cloning Livestock from Cultured Cells Creates New Opportunities for Agriculture
Wells, D.N. 한국수정란이식학회 2003 한국수정란이식학회 학술대회 Vol.2003 No.1
It is remarkable that nuclear transfer using differentiated donor cells can produce physiologically normal cloned animals, but the process is inefficient and highly prone to epigenetic errors. Aberrant patterns of gene expression in clones contribute to the cumulative losses and abnormal phenotypes observed throughout development. Any long lasting effects from cloning, as revealed in some mouse studies, need to be comprehensively evaluated in cloned livestock. These issues raise animal welfare concerns that currently limit the acceptability and applicability of the technology. It is expected that improved reprogramming of the donor genome will increase cloning efficiencies realising a wide range of new agricultural and medical opportunities. Efficient cloning potentially enables rapid dissemination of elite genotypes from nucleus herds to commercial producers. Initial commercialisation will, however, focus on producing small numbers of high value animals for natural breeding especially clones of progeny-tested sires. The continual advances in animal genomics towards the identification of genes that influence livestock production traits and human health increase the ability to genetically modify animals to enhance agricultural efficiency and produce superior quality food and biomedical products for niche markets. The potential opportunities inanimal agriculture are more challenging than those in biomedicine as they require greater biological efficiency at reduced cost to be economically viable and because of the more difficult consumer acceptance issues. Nevertheless, cloning and transgenesis are being used together to increase the genetic merit of livestock; however, the integration of this technology into farming systems remains some distance in the future.
