Accent-Epenthesis Interaction Revisited

Hyun-ju Kim,In Young Yang 한국언어학회 2016 언어 Vol.41 No.2

Kim, Hyun-ju and In Young Yang. 2016. Accent-Epenthesis Interaction Revisited. Korean Journal of Linguistics, 41-2, 239-265. This study investigates the lexical statistical patterning in North Kyungsang Korean accent-epenthesis interaction. Previous phonetic studies of Korean epenthetic vowels showed that inserted vowels are not phonetically distinct from corresponding lexical vowels (Kim & Kochetov 2011; H-J. Kim 2015), suggesting that complete neutralization would not help NKK speakers access underlying representations of epenthetic vowels to avoid accenting epenthetic vowels. We performed a corpus study to examine whether other informative cues are available in the lexical probabilistic patterning, which might help NKK speakers with the covert interaction of accent and epenthesis. The results show that the lexical stochastic patterns would not provide a cue for the accent avoidance of epenthetic high vowels. Rather, it is assumed that there is a clear distinction of lexical strata in Korean phonology, helping NKK speakers learn the interaction. We propose a formal analysis adopting comparative phonotactics developed by Hayes (in press), based on two lexical strata: NATIVE and FOREIGN (e.g., Ito and Mester 1999). This analysis provides a better approach to accounting for the covert interaction that does not involve the learnability problem.

Anisakiasis refers to parasitic infestation by nematode larvae that belongs to the subfamily Anisakinae, and this condition is seen in people who eat inadequately prepared or raw salt-water fish. While gastric anisakiasis is commonly diagnosed by endoscopic technique, intestinal anisakiasis is rare because it is less common and the clinical and radiologic features are poorly understood. The authors report a case of human anisakiasis involving the ileocecal valve in 62-year-old man who had the history of eating raw cuttlefish.

This study was undertaken to compare the storage characteristics between veal sausage and commercial pork and beef sausages in Korean domestic market. We manufactured 3_types of sausages and purchased 2_types of sausages in the market: T1(B-company product), T2(O-company product) and we made T3(smoked veal sausage), T4(smoked veal sausage with pepper) and T5(cooked veal sausage) products. During 20 days of storage at 4oC, T5 showed significantly higher in TBA value and VBN value (p<0.05). But TBA and VBN values showed normal range in all products. T3, T4, and T5 showed higher total microbial count than T1 and T2 (p<0.05). According to the result, beef and pork sausages in the market showed different total microbial count and VBN values from those made in laboratory. This result could be come from the different additives used and manufacturing processes. However, all products can be stored up to 20 days in the cooler.

이 논문에서는 원추형 자기베어링으로 지지된 고속 연삭기 로터의 정밀진동제어에 관한 연구를 수행하였다. 이러한 연구 목적으로 달성하기 위하여 전력증폭기와 원추형 자기베어링을 포함한 각 축에 대하여 이산시간 모델을 규명하였으며, 그 결과를 모의 제어기의 설계시 활용하였다. 또한 제어기의 입력값을 조절하여 자기베어링 공간내에 로터가 최적의 위치에 놓일 수 있도록 조정하였으며, 위치를 검출하는 센서와 전자기적 흡인력을 발생하는 액츄에이터 사이의 위치 불일치를 보정하는 방법을 개발하고 실험 대상에 적용하였다. 그 결과 front 방향과 rear 방향 사이의 연성 효과가 확연히 감소되었고, 로터 회전시의 진폭이 50,000 rpm에서 ±7㎛ 이내의 성능을 보이는 정밀 진동 제어를 수행하였다. In this paper, the precise vibration control problems of high speed grinding rotor supported by cone-shaped active magnetic bearings are investigated. Toward this end, each part of the system including power amplifiers and magnetic bearing systems are identified s discrete time models, and the results are used for controller design. In addition, the correction method of the position error between sensor and actuator are developed and implemented for the experiments. As a result, the coupling effect between front and rear axis are decreased and the amplitudes of rotor vibration are controlled within ±7㎛ at 50,000 rpm.

The corrosion resistance of metallic implants is essential for successful implant osseointegration. Moreover, the implant surface should have appropriate surface roughness for the attachment of the osteoblast and collagen fibrils. When titanium is exposed to air a thermodynamically very stable oxide film is formed at once. This oxide is very thin and yet it protects the metal from corrosion instantaneously. However, the oxide would not be ideal, and it would be supposed that the state of oxide film would be various by the different conditions when it is formed. The objective of this study was to evaluate the electrochemical properties and surface microstructural changes of titanium after passivation treatment or exposure to high heat (in vacuum or in air). ASTM grade 2 commercially pure titanium (Ti) disks of 10㎜ diameter were wet ground and polished with 240 and 600 grit SiC, and then ultrasonically cleaned with distilled water and ethanol. Cleansed as-received samples (As-R group) were passivated with 30% nitric acid solution at 50℃ for 15 minutes to make the Pas group. The Std-V samples were made by treating the Ti disks in vacuum quartz tube (10^-8 Torr) at 530℃ for 40 min for stress relieving, followed by annealing at 700℃ for 90 min, and then slow cooling to room temperature. The Std-A samples undergo identical procedure as the Std-V group except that it is done in air. For 530℃-V samples, Ti disks were heated at 530℃ for 40 minutes and slow cooled to room temperature. The 1000℃-V samples were produced by heating Std-V specimens again at 1000℃ for 2 hr, followed by cooling to room temperature. 530℃-A and 1000℃-A samples were also prepared. Potentiodynamic anodic polarization measurement, SEM, AFM and XRD analysis were performed to evaluate the effects of the various treatments. The difference in the mean values of E_corr between groups showed statistically significant difference (P<0.05), but that of I_corr did not show significance (P>0.05). When Ti surface was passivated there was a shift of corrosion potential (E_corr) in the noble direction and a lower corrosion current density (I_corr) value. Std-A samples showed most noble E_corr value among the tested groups. 530℃-V samples showed more noble E-corr than other tested groups except Std-A group. 1000℃-V samples showed more noble E-corr than those of Std-V sample. In the case of Std-, 530℃- and 1000℃-groups, -A sub-groups showed better corrosion resistant characteristics than -V sub-groups in regard to E-corr and I_corr values. In the SEM observations, the surfaces of the As-R samples showed only scratch line on smooth surface. In Pas samples, thick oxide layer covered the surface under high magnification observation. 530℃-A samples were covered by oxide granules, and Std-A samples had 25~50 nm-thick acicular oxides. The 1000℃-A samples were covered by coarse oxide crystals with a granule diameter of 0.1~0.6 μm having a gross appearance of milky white color, which was identified by XRD as a rutile. On the other hand, 1000℃-V samples showed an Widmansta¨tten structrue of which the orientation of the lattice is formed along crystallographic planes of the parent crystals. On the AFM observation, 530℃-A samples showed RMS roughness of 79.38 nm which is 5 times rougher than those of the As-R samples. Std-A sample had a roughness of 330.47 nm which is about 20-times rougher than that of the As-R sample. 1000℃-A samples were covered by coarse granular oxides and the roughness were about 0.56 μm. Vacuum sub-group samples showed a more smooth surface than air sub-group samples, and the oxide film was more dense. Due to variability of the surface treatment and heat treatment conditions, the process of the oxide formation seems to be affected thereby making the corrosion properties and surface micro-morphology different. However, more various electrochemical analysis together with surface analysis, and an investigation for the effects of those on the osteoblast cell adhesion and calcium phosphate apposition are needed for the improvement of the osseointegration rates of the titanium implants.

Objectives: The purposes of this study were to investigate nursing students' knowledge and attitudes toward the elderly, to examine the correlation between knowledge and attitudes, and to identify predictors of nursing students' attitudes toward the elderly. Method: Study participants were 195 nursing students who enrolled in a university located in Gwangju. Data were collected using structured questionnaires. Results: The average FAQ Ⅰ score for nursing students in this study was 50.2%. The level of nursing students' knowledge was relatively low compared to knowledge of Western nursing students in previous studies. Moreover, the average scores of psychological dimension and family/sociological dimension were lower than those of physical/physiological dimension. Negative biases were prevalent when the biased scores were computed. Nursing students also reported a little preference for working with older patients after graduation. Although the average attitude score was in a neutral range, the number of items in a negative attitude score range were more than those in a positive attitude score range. Contrary to expectation, the correlation between knowledge and attitude was not statistically significant. Nursing students who have clinical experiences with the elderly reported higher scores on FAQ Ⅰ than their counterparts. A current relationship with elderly living in their household was a significant predictor of nursing students' attitudes toward the elderly. Conclusion: Results from this study suggest that nursing education should be directed to increase the nursing students' knowledge and positive attitudes toward the elderly. Exposure to well elderly as clients before they are hospitalized or institutionalized may be helpful to increase nursing students' positive attitudes toward the elderly.
