Three aged dogs, all over 15 years old, with multiple seizure events and various neurologic signs such as head turn and ataxia were brought to the referring hospital. Two cases were tentatively diagnosed with intracranial meningioma based on magnetic resonance imaging, and one case was histopathologically confirmed as meningioma at necropsy. All dogs improved after initiation of pulsed high-dose hydroxyurea (HU) treatment. Clinical sign relapses were managed by repeating high-dose HU without obvious side effects. Pulsed high-dose HU can be applied when clinical signs are refractory to the traditionally recommended dosage for intracranial meningioma in dogs.

The current study examined the relations among teachers' beliefs, behavioral self-regulation and school readiness of preschoolers. The study sample included 229 preschoolers aged 3 to 5 attending child care centers located in Seoul and Gyeonggi area of Korea. Using Structural Equation Modeling, the paths from teachers' beliefs to children's school readiness via the mediation of their behavioral self-regulation were examined. Children's self-regulation was directly assessed using Head-to-Toe Tasks. The results showed that teachers' stronger beliefs in and responsibility for children's self-regulation and interpersonal skills significantly predicted greater behavioral self-regulation among children, which in turn, significantly influenced greater social skills and work-related skills. The contribution of teachers' beliefs and behavioral regulation to social skills and work-related skills was positive and stronger for boys.

This study has two aim: one is to clarify the restructuring of English in utterance and the other is to make use of text-setting to be applied to getting accustomed to the English rhythm and pronunciation. Clitics prove to play a crucial role on the English restructuring, and are found to be attached to their previous and to their next head or host, thus forming, respectively, an on-cliticized rhythm, trochee and a pro-cliticized rhythm, iambus. En-cliticization proves to be preferred to pro-cliticization in most types of English rhythms. Accordingly, the restructuring turn out to occur all over the levels of the Prosodic Hierarchy. That is, syllables, words and clitic groups are restructured in poetry as well as in song words, which means the necessity of restructuring throughout the levels of the Prosodic Hierarchy from the syllable to the utterance. The present study suggests a good use of a rhythmic textsetting for learners of English to get accustomed to the stress-timed rhythm as well as to such changes in pronunciation as reductions, deletions, resolutions, contractions, and rhythms in English.

Vertigo is one of the common symptoms that we can see often clinically. It is hallucination to motion of oneself or surroundings. Vertigo include not only simple whirling sensation but also leaning or falling down sensation. Particularly in benign paroxysmal positional vertigo(BPPV), the principal symptom is dizziness and accompanied by nausea, lightheadness, vomiting. They are induced by positional change which like shake ones head or lay down or turn over in one' s sleep. Cause of BPPV is otoconium fragments which are released from inner ear and stimulate ampulla of semicircular canal. So in treatment BPPV, we often using the Dix-hallpike maneuver that realignment otoconium fragments. A case of vertigo patient suggested BPPV who is diagnosed oriental medically as weakly dizziness showed prominent improvement by medicate Bojungikgi-tang and operate otoconium-realignmentation (improved Dix-hallpike maneuver) maneuver so we reported.

일관된 발화를 생성함에 있어 인격데이터(persona)의 도입을 이용한 연구가 활발히 진행되고 있지만, 한국어 데이터셋의 부재와 데이터셋 생성의 어려움이 문제점으로 지적된다. 본 연구에서는 인격데이터를 포함하지 않고 일관된 발화를 생성할 수 있는 방법으로 다중 대화 시스템에서 사전 학습된 자연어 추론(NLI) 모델을 도입하는 방법을 제안한다. 자연어 추론 모델을 이용한 관계 분석을 통해 과거 대화 내용 중 발화 생성에 이용할 대화를 선택하고, 자가 참조 모델(self-attention)과 다중 어텐션(multi-head attention) 모델을 활용하여 과거 대화 내용을 반영한 발화를 생성한다. 일관성 있는 발화 생성을 위해 기존 NLI데이터셋으로 수행할 수 있는 새로운 학습모델 nMLM을 제안하고, 이 방법이 일관성 있는 발화를 만드는데 기여할 수 있는 방법에 대해 연구한다.

This research wished to risk type and examine closely driver special quality and relation of traffic accidents by occurrence type of traffic accidents and traffic accidents seriousness examine closely relation with Severity. Fractionate traffic accidents type by eight, and driver's special quality for risk group's classification did to distinction of sex, vehicle type, age etc. analyzed relation with injury degree adding belt used putting on availability for security the objectivity with wave. Used log-Linear model and Logit model for analysis of category data. A head-on collision and overtaking accident, right-turn accident are high injury or death accident and possibility to associate in relation with accident type and seriousness degree. In risk group analysis The age less than 20 years in motor-cycle driver, taxi driver in 41 years to 50 years old are very dangerous. The woman also was construed to the more risk group than man from when related to car, mini-bus, goods vehicle etc. Therefore, traffic safety education and Enforcement for risk group that way that can reduce accident that produce to reduce a loss of lives at traffic accidents appearance a head-on collision and overtaking accidents, right-turn accidents should be studied and as traffic accidents weakness class may have to be solidified.

This essay explores the possibility of risk epistemology based on STS perspective. The starting point is the modern society's dilemma that the more technoscience has been developed, the more modern society has become riskier. The conventional risk epistemology, based on modernist dualism, has a tendency to be negligent of the relationship between risk society and technoscience, since it has only paid attention to either side of objectivity of risk or context of risk. In contrast, STS perspective on risk makes a point of focusing on the need of constructing the comprehensive risk epistemology, instead of the traditional approach based on modernist dualism. Now, this perspective goes ahead through "bridging" between objective risk(nature) and contextual risk(society) toward co-production of risk, as a result that we can no more turn our head from the emergence of new hybrids and, in turn, increase of complexity of heterogeneous networks. As such I suggest the concept of technosphere so as to reflect and display these characteristics of this perspective, and assess the potentiality of the concept.

Performance characteristics in pump mode of pump-turbines are vital for the safe and effective operation of pumped storage power plants. However, the head characteristics are different under different guide vane openings. In this paper, 3-D steady simulations were performed under 13mm, 19mm and 25mm guide vane openings. Three groups of operating points under the three GVOs were chosen based on experimental validation to investigate the influence of guide vane setting on flow patterns upstream and downstream. The results reveal that, the guide vane setting will obviously change the flow pattern downstream, which in turn influences the flow upstream. It shows a strong effect on hydraulic loss (power dissipation) in the guide and stay vanes. It is also found that the hydraulic loss mainly comes from the flow separation and vortices. In addition, in some operating conditions, the change of guide vane opening will change the flow angle at the runner inlet and outlet, which will change the Euler momentum (power input). The joint action of Euler momentum and hydraulic loss results in the change of the head characteristics.

This paper proposes a unified structural account of some instances of the English Modals and Semi-auxiliaries. The classification and the syntactic/structural description of the English Modal auxiliary verbs and verb-related elements have long been the center for many proposals in the history of generative syntax. According to van Gelderen (1993) and Lightfoot (2002), it was sometime around 1380 that the Tense-node (T) appeared in the phrasal structures of the English language, and the T-node is under which the English Modal auxiliaries occupy. Closely related is the existing evidence that English Modals were used as main verbs up to the early sixteenth century (Lightfoot 1991, Han 2000). This paper argues for a bi-clausal approach to English Modal auxiliaries with the infinitival particle 'to' such as 'ought to' 'used to' and 'dare (to)' 'need (to)', etc. and Semi-auxiliaries including 'be to' and 'have to'. More specifically, 'ought' in 'ought to' constructions, for instance, undergoes V-to-T movement within the matrix clause, just like 'HAVEAux' and all instances of 'BE', whereas 'to' occupies the T position of the embedded complement clause. By proposing the bi-clausal account, Radford's (2004, 2009) problems can be solved. Further, the historical motivation for the account takes a stance along with Norde (2009) and Brinton & Traugott (2005) in that Radford's (2004, 2009) syncretization of the two positions of the infinitival particle 'to' is no different from the 'boundary loss' in the process of Grammariticalization. This line of argument supports Krug's (2011), and in turn Bolinger's(1980) generalization on Auxiliaryhood, while providing a novel insight into Head movement of V-to-T in Present Day English.

In hard disk drives as the head to disk spacing continues to decrease to facilitate recording densities, slider disk interactions have become much more severe due to direct contact of head and disk surfaces in both start/stop and flying cases. The slider disk interaction in CSS (contact-start-stop) mode is an important source of particle generation and tribocharge build-up. The tribocharge build-up in the slider disk interface can cause ESD (electrostatic discharge) damage. In turn, ESD can cause severe melting damage to MR or GMR heads. The spindle speed of typical hard disk drives has increased in recent years from 5400 rpm to 15000 rpm and even higher speeds are anticipated in the near future. And the increasing disk velocity leads to increasing disk acceleration and this might affect the tribocharging phenomena of the slider/disk interface. We investigated the tribocurrent/voltage build-up generated in HDD, operating at increasing disk accelerations. In addition, we examined the effects with relative humidity conditions and rest time. We found that the tribocurrent/voltage was generated during pico-slider/disk interaction and its level was about $3\sim16pA$ and $0.1\sim0.3V$, respectively. Tribocurrent/voltage build-up was reduced with increasing disk acceleration. Higher humidity conditions $(75\sim80%)$ produced lower levels tribovoltage/current. Therefore, a higher tribocharge is expected at a lower disk acceleration and lower relative humidity condition. Rest time affected the charge build-up at the slider-disk interface. The degree of tribocharge build-up increased with increasing rest time.
