용언 어휘의미의 분석과 표상, 객관성 확보가 문제이다

박철우(Chulwoo Park)(朴哲佑) 형태론 2012 형태론 Vol.14 No.2

남(2008)은 용언 의미의 분석 방법으로 단의를 한정해 나가는 방식을 단계적으로 상정한다. 첫째, 상태성/동작성, 자동성/타동성, 물리성/정신성, 이동성/비이동성, 사동성/주동성, 피동성/능동성과 같은 범주 특성에 따라, 둘째, 유의어 혹은 반의어 대치에 의한 고유 특성을 포착함에 따라, 셋째, 논항 구조의 격틀이 다를 경우에도 단의를 구별하되 격 교체 구문인 경우에는 통합함으로써, 넷째, 논항의 의미 선택 제약을 살펴 동일한 의미 부류로 묶일 수 있는 최하위 결점을 포착함으로써 단의를 구분한다. 이어서, 이렇게 구분된 단의들을 서로 연관성이 있는 범위까지 통합하여 하나의 의소로 묶고, 유연성을 찾기 어려운 단의들은 동음의 다른 의소에 속하는 것으로 판정한다. 이 글에서는 우선 의소 설정의 효용에 문제를 제기한다. 공시적으로 이미 분화된 개념 의미를 유연성에 따라 통합하여 그 중 대표를 기본 의미로 제시하는 것이 의미 단위를 확인하거나 분화된 단의를 활용하는 데 어떤 유익이 있는지 알 수 없다는 것이다. 다음으로 남(2008)은 통사적 증거보다 의미의 차이를 확인해야 한다고 주장하지만, 이 글에서는 실제로는 직관으로 의미 차이를 확인하는 것으로는 객관성을 확보하기 어렵고 오히려 통사적 증거가 있을 때 의미 차이를 확인할 수 있음을 보였다. Nam (2008) offers four criteria for dividing presumed senses of a verbal lexeme. The first is the semantic difference between stative and dynamic, intransitive and transitive, physical and mental, locomotive and non-locomotive, causative and principal, and passive and active; the second the difference in semanticality after replacing the lexeme with a synonym or an antonym; the third the case-frame differences between them; and the fourth, the difference in the selectional restriction to the argument nouns between them. After establishing the senses of the lexeme, he suggests the incorporation of associable senses into the sememe of the lexeme and the separation of the remnantal ones from it. I doubt about the effectiveness of establishing the concept of a sememe and argue that syntactic evidence is more critical in establishing the senses of a lexeme than pure semantic criteria.

The purpose of this paper is to reveal what the correlation between the discourse unit and its meaning is. Here I tried to show what can be called as a discourse unit. I accept the criteria Grosz and Sidner(1986) suggested for, which is (a) linguistic structure, (b) intention structure, and (c) attention state. According to the criteria, a discourse unit should have a distinct intention(kind of discourse function) and internal information structures to make it cohesive, besides its linguistic units included. Though it is not easy to define a discourse unit formally, we can try to assess some hierarchical relations within a discourse. About the meaning of a discourse, we need to separate the explicit meaning and the implicit meaning of it. Utterances within a discourse are situationally constrained within the context(discourse domain) they occur. Therefore, to interpret the meaning of the discourse clearly, we need to make explicit all the meanings of utterances within the discourse first. And then, we should evaluate them considering other cognitive structures human minds have in common, e.g. plan, frame, schema, script, etc. and stretching all our inferential ability to exploit all the common knowledge available at the moment.

The air suspension system automatically controls the vehicle height. This height control has the advantage of being able to keep the vehicle height constantly regardless vehicle load variation so that it can maintain in the design height. In addition, aerodynamic advantages can be achieved by lowering the vehicle height at high speeds. When driving on rough roads, the impact from the road surface can be reduced by raising the vehicle height. In this study, we propose a method to improve R&H performance by selecting optimal vehicle height. And also propose selected the optimal vehicle height according to the driving situation by linking the air suspension system with the driving mode function of the vehicle. Finally, propose a method to improve the R&H according to the driving mode.

This study aims to clarify the formal and functional criteria for forming noun phrase conjunction constructions and to classify them according to their semantic features based on such criteria. While many previous studies have focused primarily on formal criteria such as noun particles, i.e., josa, this study considers the conjunction of noun phrases resulting from juxtaposition of noun phrases that share equal syntactic and semantic statuses, as is required by their common predicate. The study views previously identified indicators of noun phrase conjunction as adding not only to the formal domain of noun phrase conjunction constructions, but also to differences in meaning and other subtle semantic nuances such as modality. Based on these criteria, the study examines previously identified examples of noun phrase conjunction constructions and classifies them into logical conjunctions or logical disjunctions in accordance with our criteria for noun phrase conjunction constructions. The study also introduces logical conjunction of two negatives and the logical conjunction of a positive antecedent and a negative postcedent in the process.

There has been different traditions in analysing Korean sentences in terms of information structure, and the basic terms of a name have been used differently depending on the different assumptions about their syntactic statuses. In this paper, I offer a perspective of viewing information structure as formal phenomena in the level of discourse and thus define the basic terms of information structure in Korean systematically. On the other hand, information units in a sentence have their own information statuses in their textual or situational contexts. In this research, I review the preceding approaches of similar perspectives and reclassify the expressional instantiations of the Korean information units. In this approach, I argue that in analysing sentences in terms of information structure it is desirable to see them function as constraints to the information structure in general, because they are not encoded formally and affect distributional realizations of topic and focus separately. On the basis of the system above, I discuss the four issues in demarcating the border between information units in Korean: the linguistic encoding of topic and focus each, interactions between the scope of information structure, which is the same as the one of speech act, and the ones of other functional categories, and lastly, the interrelation between the case-markers ellipsis and focus realization. Meanwhile, I suggested that, firstly, the ratified topic in Korean can be realized only by word order without the topic marker neun, secondly, neun-marked nominals preceding a verb can be interpreted as an event topic, together with the verb as a whole and it has [+verum] feature as its matching focus unseen. Thirdly, I showed that the scopes of foci separate them from the presuppositions of the utterances they are in and, therefore, the semantic interpretation of each sentence should be interpreted as the dynamic conjointness of its presupposition and its assertion(the speech act). Finally, I made a counterargument to the pervasive idea that case-markers in Korean mark focus and pointed out that we need to see the same data with a different angle, that is to say, the case-markers within a focus is difficult to be omitted.

CDN(Content Delivery Network)은 사용자의 콘텐츠 요청에 대해 캐쉬 서버의 부하를 줄이기 위해 사용자와 가장 인접한 캐쉬 서버를 통하여 사용자에게 보다 빠르게 콘텐츠를 제공 하도록 되어있다. 현재까지의 연구는 대용량 콘텐츠 스트리밍 서비스를 위한 속도적 측면만 고려하고 있으며 콘텐츠를 빠르게 제공하기 위하여 같은 콘텐츠를 여러 캐싱서버로 분산하여 보안성이 충분하지 못한 단점이 있다. 하지만 사용자에게 충분한 보안성을 갖춘 대용량 콘텐츠를 제공하려면 암호화 연산의 증가로 인하여, 속도적 측면이 감소하므로 CDN의 본연의 기능을 잃을 수 있다. 그러므로 본 논문에서는 해시기반 스크램블링을 이용한 암호화 기법의 보안의 취약성을 분석하고 이를 극복하기 위해 보안성을 향상시킨 RECOS(Robust Encryption for COntent Secure)기법을 제안한다. 제안 기법은 시뮬레이션에서 기존 기법과 제안 기법의 속도를 비교하였으며, 기존 기법의 취약성 분석을 통하여 제안 기법의 향상된 보안성을 보였다. 결과적으로 기존의 해시기반 암호화 기법과 비교하여 속도에 차이가 거의 없음에도 불구하고 향상된 보안성을 보였다.
