The aim of thesis is to analyze dress phenomena, the semantic function and meaning of clothing were respectively on the basis of Semantics and Society by Geoffrey Leech and mentalistic semantics. To comprehend the actual clothing behaviour better, the pictures taken on the streets were used, including all kinds of the western-style and the traditional Korean costumes in Korea. The followings are the findings of the analysis. A in language, the semantic functions of the clothing are the informational, the expressive, the directive, the aesthetic, and the phatic functions. They communicate operating simultaneously. The clothing is the mentalistic semantics.

최근 자연어 및 정형언어 처리, 인공지능 알고리즘 등을 활용한 효율적인 의미 기반 지식모델의 생성과 분석 방법이 제시되고 있다. 이러한 의미 기반 지식모델은 효율적 의사결정트리(Decision Making Tree)와 특정 상황에 대한 체계적인 문제해결(Problem Solving) 경로 분석에 활용된다. 특히 다양한 복잡계 및 사회 연계망 분석에 있어 정적 지표 생성과 회귀 분석, 행위적 모델을 통한 추이분석, 거시예측을 지원하는 모의실험 모형의 기반이 된다. 하지만 대부분의 지식 모델은 특정 지표나 정제된 데이터를 수동적으로 모델링하여 분석에 활용한다. 본 논문에서는 텍스트 마이닝 기술을 통해 방대한 비정형 정보로부터 지식 모델을 구성하는 토픽인자와 관계 노드를 생성하고 이를 통합하는 방법과 정형적 알고리즘을 제시한다. 이를 위해 먼저, 텍스트 마이닝을 통해 도출되는 키워드 맵을 동치적 지식맵으로 변환하고 이를 의미적 지식모델로 통합하는 방법을 설명한다. 또한 키워드 맵으로부터 유의미한 토픽 맵을 투영하는 방법과 의미적 동치 모델을 유도하는 알고리즘을 제안한다.

서술형 문항은 수준 높은 사고능력 평가에 적합하나 채점이 쉽지 않다. 동일한 채점기준을 적용하더라도 채점자마다 서로 다른 채점을 할 수 있으므로 객관적인 채점 시스템이 필요하다. 그렇지만 채점 시스템을 구축하기 위해서는 표현 언어인 한국어 분석이 전제되어야 한다. 특히 서술형 문항의 답변은 단문형태가 아닌 복문이 내포된 복합 문장으로 표현되기 때문에 복합문의 한국어 분석이 이루어져야 한다. 본 연구는 이와 같은 서술형 문항의 자동 채점을 위해 한국어의 복합문을 구문의미 분석하는 시스템을 개발하고 시스템의 성능을 분석하였다. 이 시스템은 의미속성 사전을 활용하여 대상 구문의 의미적 제한조건을 검사하고 적합한 피수식 대상을 선별하여 구문의미분석을 실행한다. 실험 데이터에 대해 93%의 정확률을 얻어 제안한 시스템이 효과있음을 알 수 있었다. 본 연구의 시스템은 서술형 문항 채점에 활용할 수 있고 한국어 처리의 응용영역에 활용할 수 있을 것으로 기대된다.

This study aims to investigate how pre-service elementary school teachers understand 'something scientific', 'being scientific', 'scientific events' and 'scientific questions' through semantic network analysis. To achieve this purpose, this study carried out a central analysis of the frequency and density of words and the degree of connection between key words, a concentric analysis, a click analysis and a common network analysis through text semantic network analysis by using NetMiner 4.0 Program. Based on the results of these analyses, this study came to the following conclusions. Firstly, in perceiving 'something scientific', pre-service elementary school teachers recognized 'verification', 'objective' and 'experiment' as most important words. In other words, they perceived that main grounds for something scientific should be provided through clear facts, possible to be verified and accompanied by an exact and logical theoretical system. In regard to 'being scientific', they perceived 'explanation', 'objective' and 'verification' as most important words, while having a traditional point of view that science is a set that can be explained objectively. Secondly, in regard that the term, 'observation', is contained in 'scientific events', they showed a high rate of understanding it as a scientific event. In regard to scientifical reasons, they showed the highest frequency of 'observation', and for unscientific reasons, they showed the highest frequency of 'behavior'. In perceiving 'scientific questions', they showed the highest frequency of determining bacteria-related questions as scientific. As a reason why they thought as scientific, they mentioned 'observation' most frequently like 'scientific events', while mentioning 'value judgement' as a reason why they thought as unscientific most frequently. From the results of integrated network analysis, this study found out that words pre-service teachers commonly used in stating scientific events or scientific questions were overlapped with words they mentioned for scientific events or scientific questions. As a result, it was found there were many pre-service teachers having interpreted scientific words without clearly distinguishing scientific events or scientific questions.

Inthe study, a method to evaluate the door closing sound has been developed. Based on the factor analysis, various adjective pairs which describe meaning of the door impact sound have been differentiated. This approach, called Semantic difference(SD) method, was originally developed in linguistics research on order to compare diverse mother tongue. This paper introduces at first how the door sound os generated and transmitted. After that, a factor analysis which is a tool of SD method is implemented to door closing sound for 12 domestic and 1 foreign car models. During investigation, the examined models are categorized into small, medium and luxurious size automobiles. The adjective pairs which attritbute to the door quality have been factorized into three group : expensive/ smooth, powerful/ heavy, and modern/dull. It turns out that the first factor : expensive/ smooth plays the most important role in door closing sound quality.

This study is to design a Semantic Navigation Retrieval System for Oriental Medicine Articles based on a XTM so that people can search and use them more effectively than before. Keywords extracted from articles are categorized 4 topics : herbs, prescription, disease, and action. Keywords analysis Ontology is modeled based on 4 topics and their relations, and then represented Topic maps. Next, Article analysis Ontology is consist of title, author, keywords, abstracts and organization Topics from metadata. Keywords and Article analysis Ontology were integrated through Keywords Topic. Korean Medical Article Retrieval System is optimistic in terms on search results supporting semantic navigation in the information service aspects and easier accessibility because all related information are semantically connected with each different DBs.

In this study, soundscape was analyzed through physical measurement and social surveys. The results showed that, soundscape components were related to functional partitions and tourist activities, at the same time influenced by ambient noise. The sound pressure levels showed daily regular changes. Semantic differential analysis showed that the evaluation of the soundscape in urban park was rather complicated. It was still possible to identify major factors including relaxation, spatiality and environment. The results provided theoretical basis for improving urban park soundscape, and called attention to this problem.

Acute myocardial infarction (AMI) is one of the three emergency diseases that require urgent diagnosis and treatment in the golden hour. It is important to identify the status of the coronary artery in AMI due to the nature of disease. Therefore, multi-modal medical images, which can effectively show the status of the coronary artery, have been widely used to diagnose AMI. However, the legacy system has provided multi-modal medical images with flat and unstructured data. It has a lack of semantic information between multi-modal images, which are distributed and stored individually. If we can see the status of the coronary artery all at once by integrating the core information extracted from multi-modal medical images, the time for diagnosis and treatment will be reduced. In this paper, we analyze semantic relations between multi-modal medical images based on coronary anatomy for AMI. First, we selected a coronary arteriogram, coronary angiography, and echocardiography as the representative medical images for AMI and extracted semantic features from them, respectively. We then analyzed the semantic relations between them and defined the convergence data model for AMI. As a result, we show that the data model can present core information from multi-modal medical images and enable to diagnose through the united view of AMI intuitively.

말뭉치를 이용하여 통계적으로 의미역 결정(semantic role labeling)을 하기 위해서는, 의미역을 태깅하는 작업이 필수적이다. 그러나 한국어의 경우 의미역이 태깅된 대량의 말뭉치를 구하기 힘들며, 이를 직접 구축하기 위해서는 많은 시간과 노력이 필요한 문제점이 있다. 본 논문에서는 비지도 학습의 하나인 self-training 알고리즘을 적용하여, 의미역이 태깅되지 않은 말뭉치로부터 의미역을 결정하는 방법을 제안한다. 이를 위해, 세종 용언 전자사전의 격틀 정보를 이용하여 자동으로 학습 말뭉치를 구축하였으며, 확률 모델을 적용하여 점진적으로 학습하였다. 그 결과, 4개의 부사격 조사에 대해 평균적으로 83.00%의 정확률을 보였다.
