“Support /səpɔˊ:rt/” may be pronounced as follows: [səpʰ ɔˊ:rt] or [spʰɔˊ:rt]. In English phonology the latter [spʰɔˊ:rt] has more phonologically critical problems than [ə] is deleted, because [pʰ] shouldn t normally appear after [s]. Although [pʰ] is an allophone of /p/, it even distinguishes [spʰɔˊ:rt] “support”and [spʼɔˊ:rt] “sport”in meaning. This phonological inconsistency, which is not explained in rule-based phonology, is neatly explained in Optimality Theory. As Optimality Theory is a constraint-based phonology, misdistributed allophones can be also optimal forms, because optimal forms can violate constraints, which are lower than decisive ones in ranking, and be chosen by ranking constraints differently.

영어 명령표현에 나타나는 완곡어법의 정도성

The diversity of euphemistic command in English is worth studying if the aim of linguistics is to fully understand the human mind. It is clear that some euphemistic degrees are found among various command-expressions with semantic and syntactic differences although they bear the same message and usage. Euphemism is a generally innocuous expression used instead of offensive or unpleasant one. That is, the aim of euphemism is to alleviate hearers offensive and unpleasant feelings of something, and the way of euphemism, to express those indirectly. Thus, degrees of euphemism from speakers attitudes can not but be expressed in various indirect expressions. Syntactic differences show that euphemistic degrees are gradually raised or lowered in accordance with (in-)directness of expressing the same message: questions > statements > directives. And speakers attitudes also produce the euphemistic degrees of tense and mood: past > present, and subjunctive > indicative > imperative, respectively.

NiAl3 첨가가 (W,Ti)C 초경재료 소결 및 기계적 성질에 미치는 영향

박나라 ( Na Ra Park ),나권일 ( Kwon Il Na ),권한중 ( Han Jung Kwon ),임재원 ( Jae Won Lim ),손인진 ( In Jin Shon ) 대한금속재료학회(구 대한금속학회) 2013 대한금속·재료학회지 Vol.51 No.10

Co or Ni was added to cemented (W,Ti)C as a binder for forming composite structures. The high cost of Co or Ni and the low corrosion resistance of (W,Ti)C-Co or (W,Ti)C-Ni cermet have generated interest in recent years in the search to find alternative binder phases. It has been reported that aluminides have a higher oxidation resistance, a higher hardness and are cheaper materials than Co and Ni. Using a pulsed current activated sintering (PCAS) method, the densification of (W,Ti)C and (W,Ti)C-NiAl3 hard materials were accomplished within 3 minutes. The advantage of this process is not only rapid densification to near theoretical density but also the prohibition of grain growth in nano-structured materials. Highly dense (W,Ti)C and (W,Ti)C-NiAl3 with a relative density of up to 99% were obtained within 3 minutes by PCAS under a pressure of 80 MPa. The average grain sizes of the (W,Ti)C was lower than 100 nm. The hardness and fracture toughness of the dense (W,Ti)C and (W,Ti)C-NiAl3 produced by PCAS were also investigated.

메밀의 지방산 및 페놀화합물 생합성과 tyrosinase 저해 활성에 대한 몇가지 비료의 영향을 조사한 결과 다음과 같다. 메밀 식물체중의 지방산 함량은 곡류중의 지방산 함량 보다 작으며 메밀 식물체와 곡류중의 지방산은 포화지방산과 불포화지방산으로 구성되어 있으며 불포화지방산이 포화지방산보다 많은 것으로 나타났다. 메밀중의 페놀화합물은 $682.6{\sim}1822.0mg\;kg^{-1}$이며 석회 시용구의 메밀중 페놀화합물이 $1822.0mg\;kg^{-1}$로 다른 비료 시용구보다 높았다. 한편 석회가 시용된 메밀 곡류중의 sediment c의 tyrosinase 저해활성은 92.8%로 같은 처리내의 sediment c의 compound A, B, C 보다 높았다. 그러나 붕사가 처리된 메밀 곡류중의 compound C의 tyrosinase의 저해활성은 80.9%로 같은 처리구 내의 sediment나 다른 compound보다 높은 것으로 나타났다. In order to investigate the change of physiological active compounds in buckwheat with soil chemical properties and soil conditioners, we cultured buckwheat at an experimental open field station, Chonnam Provincial Agicultual Reserch and Extension Service. Fatty acids, phenolic compounds and tyrosinase inhibitory activity (TIA) from buckwheat grains and plants were analyzed. The contents of fatty acids in buckwheat plants was less than that of buckwheat grain. The fatty acids of buckwheat plants and grains were composed of saturated and unsaturated fatty acids. The contents of unsaturated fatty acids were more than saturated fatty acids. The phenolic compounds in buckwheat were from $682.6mg\;kg^{-1}$ to $1822mg\;kg^{-1}$. The phenolic compounds in buckwheat with addition of applied lime were $1822mg\;kg^{-1}$. It was higher than any other plot. The tyrosinase inhibitory activity (TIA) of sediment c in buckwheat grain with addition of applied lime was 92.8%. It was more than that of sediment a, b or compound A, B, C within the same treatment. But the TIA of compound C in buckwheat with application of borax was 81.0%. It was highest of all sediments and compounds within the same treatment.

영어 명령의 공손표현에 대한 적절성 판정

Although various kinds of sentences are employed to express command, their graded appropriateness in politeness is based on mutually exclusive language-used situations. A lot of evidences show cross-linguistic variance in expressing politeness in alliance with the cultural differences. Especially, when speaking politely in English command, indirect and respectful expressions are preferred to direct ones. Also it is reported that past tense is used for less direct and more polite expressions. By making these usages constraints and setting their rankings differently in Optimality Theory, it can be systematically explained to judge graded appropriateness of various polite expressions used in English command.

Soil Environmental Investigation of Plastic Film House in Chonnam Area

김희권,박인진,김정근,김상철,Kim, Hee-Kwon,Park, In-Jin,Kim, Joung-Keun,Kim, Sang-Chul 한국토양비료학회 2000 한국토양비료학회지 Vol.33 No.1

The investigation and the analysis of soil chemical properties, microbial flora and cultural practices in plastic house of 60 farms (pepper 20, cucumber 20, oriental melon 20) were conducted in Chonnam area film. An amount of fertilizer application of farms was more than that of standard fertilizer application. That was phosphate at two and a half times, potassium at twice and manure at three times the amount of standard application. It was inferred that excessive fertilizer application would lead to salts accumulation in soil. Continuous cropping injury would be incurred by excesive salts accumulation in soil. Even if inorganic elements in soil culturing peppers, cucumbers and oriental melons were greater than optimum level, base-saturation degree of soil culturing peppers, cucumbers and oriental melons was 40:18:12, 55:16:14 and 40:27:11 respectively. That was lower than the optimum levels (60:15:5). Therefore, crops would be affected by uptake inhibition by nutrition imbalance. Density of Fusarium is related to plant decease in soil i.e. pepper $26.2{\times}10^2\;cfu\;g^{-1}$, cucumber $75.8{\times}10^2\;cfu\;g^{-1}$ and oriental melon $6.5{\times}10^2\;cfu\;g^{-1}$. B/F of soil planted with pepper, cucumber and oriental melon was 91.2, 80.4 and 18.8, respectively. 시설재배 토양의 화학성, 미생물상 및 경종방법을 조사분석하여 시비관리 개선 및 연작장해의 사전 방지책 마련을 위한 자료를 얻고자 고추, 오이, 참외 재배지 60농가를 조사한 결과는 다음과 같다. 고추, 오이, 참외 재배농가의 시비량은 표준보다 인산은 2~2.5배, 칼리 2배였으며, 퇴비는 오이재배 농가에서 3배정도 많이 시용한 것으로 조사 되었으며 토양중 무기성분 함량이 대부분 적정치 이상이라 할지라도 고추, 오이, 참외 토양의 염기포화도가 40:18:12, 55:16:14, 40:27:11로 적정치의 60:15:5에 미치지 못하였을 뿐만아니라 양분 불균형으로 작물의 흡수 장해가 있었을 것으로 추정 되었다. 시설 하우스 토양의 미생물 B/F 값은 고추 91.2, 오이 80.4, 참외 18.8로 연작 년수가 긴 것으로 조사된 참외 재배토양의 미생물상이 열악한 것으로 나타났다. 토양 pH가 증가할수록 곰팡이와 Fusarium의 밀도는 감소 하고 방선균은 증가 하였으며, 토양 유기물 함양이 증가 할수록 모든 미생물의 밀도가 증가 하였으며 세균은 유의성이 안정 되었다. 세균, 곰팡이, 및 Fusarium의 밀도는 EC가 증과 할수록 감소 하였다. 따라서 시설하우스 재배시는 토양분석후 시비처방에 의해 인산과 칼리를 감비하고 염기포화도를 조절할 수 있도록 시비해야 할 것으로 사료되었다.
