한국어의 어휘 의미 정보를 명확히 파악하기 위해서는 어휘 의미 체계를 구축해야 한다. 본 논문에서는 어휘 의미 체계 구축의 단계 중 하나인 용언의 의미 군집화를 연구하였다. 용언의 하위범주화 논항(주어 및 목적어)과 선택 제약정보, 부사의 결합정보를 이용한 이전의 연구와는 달리 의미태그가 부착된 사전 뜻풀이의 용언정보를 이용하여 용언의 의미 군집화를 시도하였고, 표제어와 뜻풀이 용언 사이 관계의 종개념과 유개념 관계를 이용하여 계층적 의미 군집화를 시도하였다. 그리고 특정 범주의 일반 샘플을 이용했던 특정 용언의 부류가 아닌, 사전에 존재하는 대부분의 용언들을 대상으로 연구를 진행하였다. 본 논문에서 다의어 수준에서 구분된 총 106,501개의 용언(85,754개의 동사와 20,747개의 형용사)을 대상으로 한국어 용언 의미계층 군집 2,748개를 생성하였다. 이 중 순환정의 군집은 130개가 나타났으며, 중간 계층의 서브군집으로 261개가 나타났다. 군집 내 계층의 최대 깊이는 16단계였다. 그리고 용언 의미 군집 평가를 위해 세종사태의미부류와 비교해 보았다. 그 결과 70.14%의 응집도를 보였다.

The department of education developed editing data of fisheries and shipping high school subject in 1987. But as change to informational society, the new term and predicate were built on a textbook of fisheries and shipping that was not in the past. Terms came into being in this way, it was used indiscreetly by spending a different expression on a textbook. In this study based on currently subject of fisheries and shipping high school 36books, examined an elementary school junior high school and a definition related term in order to solve these problems. Specialist on each field selected term and the predicate which is objective and proper. Especially field of fisheries and shipping uses a japanese term as it is. So there are a lot of the terms that is hard for students. Using these terms yet, the term that meaning delivery is uncertain and hard expression is going to carry out role to convert to a clear and easy term through this study.

This study focuses on the behavioural lexical classification for extracting animation character actions and the analysis of the character's upper and lower body movements. The behaviour and state of characters in the animation industry are crucial, and digital technology is enhancing the industry's value. However, research on animation motion application technology and behavioural lexical classification is still lacking. Therefore, this study aims to classify the predicates enabling animation motion, differentiate the upper and lower body movements of characters, and apply the behavioural lexicon's motion data. The necessity of this research lies in the potential contributions of advanced character motion technology to various industrial fields, and the use of the behavioural lexicon to elucidate and repurpose character motion. The research method applies a grammatical, behavioural, and semantic predicate classification and behavioural motion analysis based on the character's upper and lower body movements.

한국어의 어휘의미 정보를 명확히 파악하기 위해서는 어휘 의미 체계를 구축해야 한다. 본 논문에서는 어휘 의미 체계 구축의 단계 중 하나인 용언의 의미 군집화를 연구하였다. 주어 및 목적어의 논항 구조와 선택 제약정보, 부사의 결합정보를 이용한 이전의 연구와는 달리 의미태깅이 된 사전 뜻풀이의 용언정보를 이용하여 용언의 의미 군집화와 간단한 계층화를 시도하였다. 그리고 특정 부류의 일반 샘플을 이용했던 특정 용언의 부류가 아닌 사전에 존재하는 대부분의 용언들을 대상으로 연구를 진행하였다.

This study examines the millennial generation, who express themselves and share information on social media after experiencing constantly changing 'hot places' (places of interest) in contemporary cities, with the goal of analyzing space consumption behaviors. Data were collected via an Instagram crawler application developed with Python 3.4 administered to 19,262 posts using the term 'hot places' from November 1 and December 15, 2019. Issues were derived from a text mining technique using Textom 2.0; in addition, semantic network analysis using Ucinet6 and the NetDraw program were also conducted. The results are as follows. First, a frequency analysis of keywords for hot places indicated words frequently found in nouns were related to food, local names, SNS and timing. Words related to positive emotions felt in experience, and words related to behavior in hot places appeared in predicate. Based on importance, communication is the most important keyword and influenced all issues. Second, the results of visualization of semantic network analysis revealed four categories in the scope of the definition of "hot place": (1) culinary exploration, (2) atmosphere of cafés, (3) happy daily life of 'me' expressed in images, (4) emotional photos.

In recent years, the skyline query paradigm has been established as a reliable method for database query personalization. While early efficiency problems have been solved by sophisticated algorithms and advanced indexing, new challenges in skyline retrieval effectiveness continuously arise. In particular, the rise of the Semantic Web and linked open data leads to personalization issues where skyline queries cannot be applied easily. We addressed the special challenges presented by linked open data in previous work; and now further extend this work, with a heuristic workflow to boost efficiency. This is necessary; because the new view on linked open data dominance has serious implications for the efficiency of the actual skyline computation, since transitivity of the dominance relationships is no longer granted. Therefore, our contributions in this paper can be summarized as: we present an intuitive skyline query paradigm to deal with linked open data; we provide an effective dominance definition, and establish its theoretical properties; we develop innovative skyline algorithms to deal with the resulting challenges; and we design efficient heuristics for the case of predicate equivalences that may often happen in linked open data. We extensively evaluate our new algorithms with respect to performance, and the enriched skyline semantics.

Objectives : The Oriental medical device industry is expected to continue to experience significant growth. It should increase its global market share rather than focusing on the domestic market. Countries around the world self-regulate their domestic market, so this study aims to aid in the development of a particular overseas market by introducing the U.S.(the largest market) medical device registration and approval process. Methods : For an understanding of the US medical device licensing process, we researched the relevant regulatory organization (FDA), the history, definition and classification of medical devices, the approval and 510(k) submission process related to substantial equivalence, IEC 60601-1 Edition 3, usability tests, and so on. Results : Medical devices in the United States are assigned to one of three regulatory classes: Class I, Class II and Class III, based on the level of control necessary to assure the safety and effectiveness of the device. If a company's device is classified as Class II and if it is not exempt, a 510k will be required for marketing. 1) A 510(k) is a premarket submission made to the FDA to demonstrate that the new device to be marketed is "substantially equivalent" to a legally marketed device (predicate device) 2) The IEC 60601-1 Edition 3 preparation process, which contains information related to usability, is expensive and time-consuming but a critical requirement. Conclusions : Although the U.S. market has high barriers to entry, access to this, large overseas market will encourage development of the Oriental medical device industry and commercial value enhancement is expected.
