Variable Vowel Adaptations of English Word-final Stops in Korean Loanword Phonology

유나영,홍성훈 한국중원언어학회 2010 언어학연구 Vol.0 No.17

This paper examines the patterns of vowel epenthesis in English loanword adaptation that occur when English loanwords that end in postvocalic word-final stops are borrowed into Korean. We then provide a variable rule analysis of the three vowel epenthesis patterns: vowel epenthesis, no vowel epenthesis and variable vowel epenthesis, according to four linguistic factor groups, the tenseness of pre-final vowel (tense vs. lax), the voicing of the final stop (voiced vs. voiceless), the place of articulation of the final stop (coronal vs. labial vs. dorsal), and the number of syllables (monosyllabic vs. polysyllabic). Our analysis reveals that ‘tense’, ‘voiced’, ‘coronal’, and ‘monosyllabic’ are, in this order, the most significant factors for vowel epenthesis, whereas ‘labial’, ‘lax’, ‘polysyllabic’, ‘dorsal’, and ‘voiceless’ are the most crucial factors for no vowel epenthesis. It is also found that variable vowel epenthesis is most likely to occur when the factors are set as ‘lax’, ‘coronal’ and ‘voiceless’.

Background: Cerebral small vessel disease (SVD) induces vascular cognitive impairment (VCI) such as subcortical vascular dementia (SVaD) and subcortical vascular mild cognitive impairment (svMCI). We compared MRI parameters between SVaD and svMCI and determined which MRI parameters best correlated with cognitive function and disability on cross-sectional and longitudinal analyses within them. Methods: Twenty-four patients with SVaD and twelve with svMCI were recruited. They underwent multimodal MRIs including fluid-attenuated inversion recovery lesion load, lacunar infarct number, and fractional anisotropy (FA) and mean diffusivity (MD) from diffusion tensor imaging (DTI), neuropsychological testing, Sum of Boxes of Clinical Dementia Rating Scale (CDR-SB), Barthel Index, and the Korean version of a Geriatric Depression Scale (GDS-K). Seventeen patients were retested after 20 months for a brain MRI and clinical evaluation. Results: There were significant differences in average MD and peak height of MD histograms within normal-appearing brain tissue (NABT) between SVaD and svMCI patients. In the cross-sectional analysis, average MD within NABT significantly correlated with the composite neuropsychology score (r=-0.80, p<0.001), the composite executive function score (r=-0.67, p< 0.001), and the CDR-SB (r=0.54, p=0.001), and the Barthel Index correlated with peak heights of the MD histograms (r=0.37, p=0.03) in NABT. Changes of CDR-SB was associated with changes of average MD within WMH (r=0.57, p=0.02), and changes of GDS-K was associated with changes of WMH volume (r=0.51, p=0.04) on a longitudinal scale. Conclusions: DTI parameters in NABT correlated with cognitive impairment and disability in VCI associated with SVD. Clinical progression of SVD was associated with some increment of WML volume and ultrastructural changes in WMH.

Universal soil loss equation (USLE) had been employed to estimate potential soil loss since it was developed from the statewide data measured and collected in the United States. The equation had an origin in average annual soil loss estimation though, it was modified or improved to provide better opportunities of soil loss estimation outside the United States. The equation has five factors, most studies modifying them to adapt regional status were focused on rainfall erosivity factor and cover management factor. While the conservation practice factor (USLE P factor) is to represent distinct features in agricultural fields, it is challenging to find studies regarding the factor improvements. Moreover, the factor is typically defined using slopes. The factor defining approach was suggested in the study, the approach is a step-by-step method allowing USLE P factor definition with given condition. The minimum condition is slope and field location to provide an opportunity for using in any GIS software and to reflect regionally distinct features. If watershed location, slope, crop type, and mulching type on furrows are given, detailed definition of the factors are possible. The approach was developed from field survey in South-Korea, it is expected to be used for potential soil loss using USLE in South-Korea.

The Trump administration's strategies toward China and the Reagan administration's strategies toward the Soviet Union are significant in showing the transformation of America's hegemonic strategy. Therefore, this study compared Reagan's Soviet Union Strategy to Trump's China strategy with the critical official documents of the United States, dividing the strategy of the military, economic, and political system from the perspective of the grand strategy. As a result, Reagan Administration used an aggressive military strategy with alliances, an indirect retaliation economic one related to national security, and a political system strategy that encouraged liberal democracy. In the case of the Trump administration, they did a robust military strategy, a direct trade retaliation against China based on illiberal hegemony. However, they shifted their political system strategy from an appeasement approach to a more stubborn one. 레이건 행정부의 대 소련전략과 트럼프 행정부의 대중국전략은 미국 패권전략의 변화를 볼 수 있다는 측면에서 매우 중요하다. 따라서 이 연구는 미국 주요 문서를 중심으로 1981년부터 1985년까지 레이건 행정부의 대소전략과 2017년부터 2021년까지 트럼프 행정부의 대중전략을 대전략의 관점에서 군사, 경제, 정치체제 부문으로 나누어 비교하였다. 연구결과, 레이건 행정부는 봉쇄전략이라는 대전략의 원칙하 공세적 군사전략, 유럽을 통한 간접보복 방식의 경제 전략, 자유 민주주의 독려 전략을 시행하였다. 트럼프 행정부의 경우 비자유 패권주의라는 대전략의 전제하에 중국에 대한 공격적인 군사전략, 직접 무역보복 전략을 행하였다. 그러나 정치체제 부문의 전략에 있어서는 초기 유화책에서 강경책으로 선회하였다.

Universal soil loss equation (USLE) is used to estimate soil loss solely or employed in any hydrologic models. Since soil erosion has been an issue in South Korea for decades, the Ministry of Environment enacted a law to regulate soil erosion in 2012, which is the Notification of topsoil erosion status. The notification is composed of preliminary and field investigations, the preliminary investigation suggests to use USLE and provides USLE factors. However, the USLE factors provided in the notification was prepared at least 10 years ago, therefore it is limited to reflect recent climate changes. Moreover the current yearly USLE approach does not provide an opportunity to consider seasonal variation of soil erosion in South Korea. A GIS-based model was therefore applied to evaluate the yearly USLE approach in the notification. The GIS-based model employs USLE to estimate soil loss, providing an opportunity to estimate monthly soil loss with monthly USLE factor databases. Soil loss was compared in five watersheds, which were Geumgang, Hangang, Nakdonggang, Seomjingang, and Yeongsangang watersheds. The minimum difference was found at Seomjingang watershed, the yearly potential soil loss were 40.15 Mg/ha/yr by the notification approach and 34.42 Mg/ha/yr by the GIS-based model using monthly approach. And, the maximum difference was found at Nakdonggang watershed, the yearly potential soil loss were 27.01 Mg/ha/yr by the notification approach and 10.67 Mg/ha/yr by the GIS-based model using monthly approach. As a part of the study result, it was found that the potential soil loss can be overestimated in the notification approach.

This study aimed to investigate pesticide residues in 160 stalk and stem vegetables marketed in Northern Gyeonggi-do. The QuEChERS method using GC-MS/MS and LC-MS/MS was employed to analyze the residues of 341 pesticides in the samples. The maximum or lower than the residue limit was recorded in 75 samples (46.9%), while 4 samples (2.5%) exceeded the maximum residue limit (MRL). Thirty-nine kinds of residual pesticides were detected including fungicides (14), insecticides (22), herbicides (2), and plant growth regulator (1). Carbendazim and pendimethalin were the most frequelntly detected pesticides. Fenitrothion, procymidone, and diazinon exceeded MRL in garlic chives, and Welsh onion. This indicated that these vegetables along with water celery should be constantly monitored.

Soil erosion has been issued in many countries since it causes negative impacts on ecosystem at the receiving water bodies. Therefore best management practices to resolve the problem in a watershed have been developed and implemented. As a prior process, there is a need to define soil erosion level and to identify the area of concern regarding soil erosion so that the practices are effective as they are designed. Universal Soil Loss Equation (USLE) were developed to estimate potential soil erosion and many Geographic Information System (GIS) models employ USLE to estimate soil erosion. Sediment Assessment Tool for Effective Erosion Control (SATEEC) is one of the models, the model provided several opportunities to consider various watershed peculiarities such as breaking of slope length, monthly variation of rainfall, crop growth at agricultural fields, etc. SATEEC is useful to estimate soil erosion, however the model can be implemented with ArcView software that is no longer used or hard to use currently. Therefore SATEEC based on ArcView was rebuild for the ArcGIS software with all modules provided at the previous version. The rebuilt SATEEC, ArcSATEEC, was programmed in ArcPy and works as ArcGIS Toolset and allows considering monthly variations of rainfall and crop growth at any watershed in South-Korea. ArcSATEEC was applied in Daecheong-dam watershed in this study, monthly soil erosion was estimated with monthly rainfall and crop growth variation. Annual soil erosion was computed by summing monthly soil erosion and was compared to the conventional approach to estimate annual soil erosion. The annual soil erosion estimated by the conventional approach and by summing monthly approach did not display much differences, however, ArcSATEEC was capable to provide monthly variation of soil erosion.

명사-명사 결합 개념의 이해에서 마음 갖춤새와 이야기맥락의 효과

유나영,신현정 심리과학연구소 2005 심리과학연구 Vol.4 No.-

맥락의 다의성을 갖는 명사-명사 결합개념의 이해에 미치는 효과를 알아보기 위해서 2개의 실험을 수행하였다. 실험 1에서는 지시문과 연습 시행을 통하여 결합개념을 관계적이거나 속성적으로 해석하도록 실험참가자의 마음갖춤새를 유도하였으며, 두 실험 모두에서 중성조건에서 해석이 관계적이거나 속성적으로 심하게 편향된 결합개념의 해석 패턴과 이해 시간을 측정하였다. 그 결과 마음갖춤새는 결합개념의 해석패턴에는 별 영향을 미치지 않았으나, 이해 시간에서는 영향을 주었다. 즉, 마음갖춤새에 따라서 편향결합개념의 해석 패턴이 바뀌는 경우는 소수에 불과하였으나, 마음갖춤새와 개념 해석 편향성이 일치할 때는 이해시간이 빨라지고 불일치할 때는 느려지는 결과가 나타났다. 한편 이야기맥락은 편향결합개념의 해석 패턴에는 상당한 영향을 미쳤으나 이해시간에서는 차이를 초래하지 않았다. 즉, 편향결합개념임에도 불구하고 이야기백락에서는 대부분이 그 맥락에 적절한 의미로 해석되었지만 이해시간을 촉진하거나 억제하는 결과는 나타나지 않았다. 연구의 결과를 개념적, 방법론적인 문제점들과 연계하여 논의하였다. Two experiments were conducted to investigate the effects of mental set and story context on the comprehension of ambiguous noun-noun combined concepts that are biased to thematic relation or property interpretations in the neutral condition. In Experiment 1. participants' mental set was induced through the instruction and the practice trials. and the short stories consisted of 4 sentences were used as context in Experiment 2. In both experiments, interpretation patterns and comprehension times were measured. The results of Experiment 1 showed that the mental set has not so much effect on the interpretation patterns but has significant effect on the response times. Response times were shortened when the mental set was consistent with the interpretation bias of the combined concepts and were lengthened when they were inconsistent with each other. On the other hand, story context in Experiment 2 showed the reversed results. That is, the combined concepts were interpreted according to the story context in spite that they are severely biased in interpretation in the neutral condition. whereas the response times did not show any differences. The results of this study were discussed with relation to the conceptual and methodological problems.
