As the 4th Industrial Revolution emerged as a key to improving national competitiveness, OCR technology, one of the major technologies in the 4th industry is in the spotlight. Since characters in various images contain a lot of information, OCR technology for recognizing these characters has evolved into technology used in many industries. In this paper, trends in OCR technology were identified and predicted using thesis data published in 'RISS' and patent data by International patent classification (IPC) under the theme of Optical character recognition (OCR). For patent data 20,000 patents related to OCR technology from 2002 to 2020 were used as data, and 432 papers from 2012 to 2022 were used as data. Through time-series analysis, each patent data and thesis data were investigated since when OCR technology has developed, and various keyword analysis predicted which technology will be used in the future. Finally, the direction of future OCR technology development was presented through network association analysis with patent data and thesis data.

This thesis shows controlling the mobile robot with distance information gotten with ultrasonic sensors, and analysis of captured image. The ultrasonic sensors supplies more accurate distance data in limited area but shows unstable data unlimited area while image data generally shows stable data, but this requires so much time because of amounts of calculation. So this thesis considers the merits of ultrasonic sensors and image to implement robot system .

This reach is to comprehend the trend of father-related studies in Korea. The result of analyzing 161 father related thesis published from first issue until 2015.12 issue on 9 journals came out as below. First, father-thesis have increased. But the proportion of it remains for only 1~2% out of total 9 academic journals. Also the increased amount is very small considering the increasing rate of mother-thesis. In other words, the increased number of father-thesis is due to increased number of total amount of academic journals, which cannot be interpreted as the academic interest about fathering has grown. Second, almost of father-thesis were the empirical research and quantitative approach took the most part. Also father-thesis focus on 'what father's role is' and 'how much he does it'. Due to generalization of double-income family and an increase of interest about fathering, operational definition and a measurement issue is growing. Third, the topic of research which handles influence of father to child ranges from social relationship to social and emotional development. Also an interest of awarness development is growing. Meanwhile, research of father's influence to child development depends on cross-sectional data. Only few used vertical material.

이 글은 1970년대 이후 서유럽 선진산업국가들에서 새로운 사회정치적 갈등으로서 재흥한 지역주의를 그 전개양상과 유형, 성격을 중심으로 살펴보고, 그에 대한 논리적 설명들을 개념적 차원에서 분류 서술한 것이다. 특히 사회과학에서 사회발전론으로서 지배적 위상을 지닌 근대화론을 개괄하고, 그 논의를 바탕으로 지역주의를 둘러 싼 제반 테제들을 분화론, 지속론, 과정론, 수렴론 그리고 탈분화론으로 나누어 발견론적이로 구성적 관점에서 접근하였다. 이들 테제를 실증적 자료에 의거하여 모두 구체적으로 검토하기에는 여전히 어려움이 있으나 지역주의가 사회과학 일반에서 이론적으로 주목받을 만한 가치가 있으며, 또한 지역에 대한 상이한 메타이론적 개념구성은 사회지리학에서 지역개념을 정교화하는 데에도 시사점을 줄 것으로 생각된다.

The first part of this thesis discusses the types and the properties of errors, one of which makes up systematic errors of measurements, removable by detecting their causes, the other errors of accidental causes which can not be removed. The final part of this thesis deals with the historical background of the Gaussian distribution by Hershel, Hagen, Laplace and Gauss from the late 18th century to the early 19th century. It can be concluded that the accidental idea and the treatment of accidental error distribution by Gauss Is the best one based on the assumption that the most probable value of true value is the arithmetic mean of data, obtained by repeated measurements of a given quantity.

본 논문에서는 개념망을 이용한 효율적인 정보검색을 위한 방법을 제안한다. 본 논문은 일반적인 개념망을 기반으로 시스템을 설계하였기 때문에 온톨로지와 접근 방식은 같지만 사용자가 보다 효율적으로 정보검색을 하고자 하는 객체와 개념사이의 협업 관계를 구축하여 사용할 수 있도록 개념망을 제안한다. 제안한 시스템은 다음과 같다. 첫 번째, 입력 키워드 중심의 키워드 개념망과 전문가 그룹이 추천한 전문가 개념망 그리고 테마 개념망 이러한 세 종류의 개념을 이용하여 협업적 검색을 하며, 이를 기반으로 사용자가 원하는 정보를 검색할 수 있는 효율적인 검색 시스템을 제안한다. 그리고 전문가 개념과 키워드 개념이 결합되어 키워드의 빈도 및 카테고리의 빈도를 제공함으로써, 사용자가 입력한 검색어와 관련된 키워드를 추천하는 역할을 할 수 있다. 그리고 테마 개념망을 이용하여 사용자의 관심 테마에서 사용되는 키워드 또는 카테고리를 알려주는 기능도 제공한다. 두 번째, 사용자가 입력한 키워드가 없을 경우 2차 검색을 통해 입력 키워드와 관련 있는 키워드를 제공해줌으로써 관련키워드를 이용하여 검색의 목적달성이 가능하다. 세 번째, 이러한 정보들은 대부분 분산되어 관리되고 있기 때문에 이렇게 분산되어 관리되는 정보는 표현방식이 다를 뿐만 아니라 시간에 따라 정보가 변하게 된다. 따라서 분산된 정보의 효율적 데이터 접근 및 통합을 위해 XMDR(eXtended Mata-Data Registry)을 이용하였고, 본 논문에서는 분산된 데이터를 통합하기 위한 기법 및 검색 시스템을 제시한다.
