러시아어 시간표현에서 시간의 이동과 방향성 연구

권용재 한국슬라브어학회 2015 슬라브어연구 Vol.20 No.2

This study, first of all, investigates several different approaches to nature of the conceptualization of time as well as three fundamental cognitive models of temporality, based on movement metaphorically. The researcher of this study is exploring the possibility of determination of direction of temporal movement in Russian worldview to reach our ultimate aim. The present problem is solved by analysis of temporal metaphoric expression of modern Russian. Consequently, the problem of defining the direction of temporal movement in Russian is confined to a separate fraction of time that is in a state of movement or located in a space. In the metaphorical model of temporal movement, the future to the past and vice versa, both of the directions of temporal movement are taken into account in reference to Russian worldview. Nonetheless, of the two, the former(from the future to the past) direction of temporal movement can be considered more dominant. 러시아어 시간표현에서 시간의 이동과 방향성 연구 105 The direction of temporal movement depends on movement subjects, i.e. Time, Person(Observer), or Time(Person) to move with person(time). Thus the principle to separate directional models of temporal movement according to movement subjects consists in a mode of the conceptualization of time designed by a language user, who, engaging the world through his thoughts and views, forges a relationship between ego and the world around him, and interprets it on his own cultural background.

This paper conducted a study on the selection of control techniques and sensors to improve the driving stability of multi-degreeof-freedom spherical motors. The spherical motor is based on the induction motor operating method and has the characteristic of being capable of driving and steering at the same time. However, due to the structural characteristics of the spherical motor, vibration is severe during driving, and it is difficult to attach a sensor for estimating the rotor angle during rotating and steering. Therefore, through the experiment, a structure formed of steel was installed in the axial direction during driving, and A technique of generating and controlling magnetic poles was applied. During steering, a sensor considering the structure of a multi-degree-offreedom spherical motor was selected to estimate the rotor angle. Finally, a technique for obtaining rotor angle information was studied, and its applicability was reviewed.

러시아어 동사 의미구조의 다상황적 분석- рисовать 동사를 중심으로 -

The polysituational approach proposed by N. B. Lebedeva for verb semantic analysis presupposes the possibility that the verbs indicate a dynamic situation that changes over time, and that there are potential objects involved. According to the analysis of a “situateme” (ситуатема), which is the cognitive unit that includes several situations realized both explicitly and implicitly, the semantics of verbs is structured in the form of a field divided into lexicalized situations and peripheral propositions (retrospective, perspective). This polysituational approach not only reveals and describes the deep structures of verbal meanings, but also allows them to be expressed in terms of the dynamics of the situation. The polysituational analysis of semantics of the verbs shows that it is an efficient way to study the semantic derivation of verbs that mean to depict by such lines and colors, such as рисовать-1, писать, зарисовать, рисовать-2. In other words, by comparing and contrasting the situateme of the basic verb (рисовать-1) representing the typical situation of the lexical semantic group and the polysituational structure of the derivational verbs, it is possible to explore the mechanism of how the lexical semantics of the verbs is developed in various forms of derivation. .

기상변화가 총요소생산성과 국내 경제에 미치는 영향에 관한 연구

We analyzed firm-level data to figure out how the meteorological change affects the Korean economy. Using the Mining and Manufacturing survey, we calculated total factor productivity (TFP hereafter) based on the methodology proposed by Good et al.(1999). We ran panel fixed effect regression of TFP on meteorological variables such as precipitation, standard deviation of precipitation, HDD and CDD. From the analysis, we found that meteorological changes significantly affect TFP in several industries. Based on the findings from the TFP study, we estimated dynamic computable general equilibrium(CGE hereafter) model to examine the effect of meteorological change on GDP. Estimating dynamic CGE model, we found first that there is a positive relationship between GDP and TFP and second that changes in TFP affect GDP by-1.39 to 5.16 percent. 본 연구는 기업단위 미시자료를 이용하여 기상변화가 총요소생산성과 우리나라 경제에 미치는 영향을 분석하였다. 우선 통계청의 광업제조업통계조사의 패널자료를 이용하여 Good et al.(1999)이 제안한 방식에 기초하여 총요소생산성을 계산하였다. 그리고 강수량, 냉난방도일 등 기상변수를 활용하여 패널회귀분석을 실시함으로써 기상변화가 총요소생산성에 미치는 효과를 분석하였다. 분석 결과 여러 산업에서 기상변화가 총요소생산성에 통계적으로 유의한 영향을 미치는 것으로 나타났다. 더불어 기상변화가 국민경제에 미치는 영향을 파악하기 위해 기업단위분석 결과를 기초로 동태적 CGE 모형을 추정함으로써 GDP에 대한 기상변화의 중장기 파급효과를 분석하였다. 분석 결과 실질GDP는 총요소생산성이 증가한 경우 대체로 증가하고 반대의 경우 부정적인 영향을 미치는 것으로 나타났으며 기상변화는 장기적으로 GDP를 약 -1.39%에서 5.16%사이의 수준으로 변화시키는 것으로 나타났다.

In this study, an additive manufacturing (AM) optimization process experiment was conducted using high-hardness metal powders (AISI M4) that can be used for mold repairs. The process variables applied in the experiment were the laser power, laser head moving speed, and powder feed rate, and the manufacture cross section was analyzed through one-pass manufacturing. The AM efficiency was evaluated for each process with respect to the layer height, dilution ratio, and global energy density. In the case of the layer height, the AM efficiency was good under the condition of the laser output of 500 W. In the case of the dilution ratio, the AM efficiency was good under the conditions of a powder feed rate of 6 g/min and laser head moving speed of 500 mm/min. Finally, the GED values of the process variables applied in this experiment were calculated, and the AM efficiency was excellent at values between 60 and 108 J/mm2.

Variation of photoluminescence spectral line shape of monolayer WS2

권용재,김강원,김원택,류순민,정현식 한국물리학회 2018 Current Applied Physics Vol.18 No.8

The origin of the variation of photoluminescence (PL) spectra of monolayer tungsten disulfide (WS2) is investigated systematically. Dependence of the PL spectrum on the excitation power show that the relatively sharp component corresponds to excitons whereas the broader component at slightly lower energy corresponds to negatively charged trions. PL imaging and second harmonic generation measurements show that the trion signals are suppressed more than the exciton signals near the edges, thereby relatively enhancing the excitonic feature in the PL spectrum and that such relative enhancement of the exciton signals is more pronounced near approximately armchair edges. This effect is interpreted in terms of depletion of free electrons near the edges caused by structural defects and adsorption of electron acceptors such as oxygen atoms.

The article analyzed elements of spoken language found in the syntax of Russian mass media text. The study shows that parceled construction as the elements of analytism in a sentence structure, parenthetical construction, incomplete sentences, dialogical elements (including question-answer constructions, rhetorical questions, responding, and imperative sentences), exclamatory sentences and sentences with interjections, i.e., elements of spoken language in the syntax permeate sentence structure in the mass media texts, that is believed to have formal properties of the written language style. Elements of spoken language listed above heighten affective involvement of the readers, enhance reliability of information provided from the media. In consequence, the fields in which a standard, normative written language on complete structure might be compatible with informal spoken language are formed in the language of modern Russian mass media.
