The purpose of this study is to find out the distributional properties of case marker ‘uy’ by genre, focusing on the construction of the noun phrase ‘N1-uy N2.’ For this, nouns preceding and following ‘uy’ were classified into ‘the noun for a person,’ ‘the noun for a thing,’ ‘the noun for an event,’ ‘the noun for a state,’ ‘the noun for an abstract object,’ and ‘the noun for a location.’ And the distribution of each nominal type and differences in the use of ‘N1-uy N2’ construction in novels, newspapers, and academic articles were examined. As a result, it was found that the noun for a person accounted for the largest portion for the position of N1 in novels, the noun for a thing in newspapers, and the noun for an abstract object in academic articles, respectively. At the position of N2, the noun for a thing was most frequently found in novels and the noun for an abstract object in newspapers and academic articles, respectively. Lastly, to look at the ‘N1-uy N2’ construction, the construction of ‘[the noun for a person]-uy [the noun for a thing]’ was found to be used most in novels, the construction of ‘[the noun for a thing]-uy [the noun for a thing]’ in newspapers, and the construction of ‘[the noun for an abstract object]-uy [the noun for an abstract object]’ in academic articles, respectively. Besides, it was found that characteristic figures of speech or idiomatic expressions were used according to genres. This reveals that the distribution of case marker ‘uy’ differs according to the genres of texts, and shows that grammatical description considering genres from the aspect of language use is necessary since this distributional difference can be explained by linguistic tendencies.

의류 상품평 텍스트에 나타난 ‘좋다’ 구문의 의미와 극성 연구

This study aims to assess the meaning and polarity of ‘johta’ constructions as occurring in clothing product reviews. Twelve types of constructions were identified and analyzed: -i johta, -ko johta, (N-i) johta, -ase johta, -ki(ey) johta, -myen johta, -ni(kka) johta, -ato johta, -nun key johta, -nuntey johta, -konun johta, -ciman johta. Each construction has its own particular meaning, which is closely linked to the semantic function of the connective ending that partly composes the construction. Findings reveal that ‘johta’ constructions in clothing product reviews are not always used to convey an ‘evaluation’ but can also express ‘advice’, ‘wish’, ‘request’ depending on the construction. Moreover, the polarity of each construction was identified based on the analysis of the examples extracted from the Clothing Product Review Corpus. As a result, most ‘johta’ constructions indicate a [+positive] polarity; nevertheless, the construction ‘-myen johta’ tends to be [-positive] while the construction ‘-konun johta’ always occur with both negative and positive evaluations.

Lane keeping assist and departure prevention system are the key functions of ADAS. In this paper, we propose lane detection method which uses Gaussian function based RANSAC. The proposed method consists mainly of IPM (inverse perspective mapping), Canny edge detector, and Gaussian function based RANSAC (Random Sample Consensus). The RANSAC uses Gaussian function to extract the parameters of straight or curved lane. The proposed RANSAC is different from the conventional one, in the following two aspects. One is the selection of sample with different probability depending on the distance between sample and camera. Another is the inlier sample score that assigns higher weights to samples near to camera. Through simulations, we show that the proposed method can achieve good performance in various of environments.

지일용(Illyong Ji),고영욱(Youngwook Ko),서은영(Eunyoung Seo),정재용(Jae-Yong Choung) 한국기술혁신학회 2011 기술혁신학회지 Vol.14 No.2

한국 영화는 개화기에 도입된 이후 현재 세계적으로 호평 받는 수준으로 발전하였으며 산업적으로도 큰 성장을 이루었다. 그러나 최근 디지털시네마 및 입체영화의 등장 등 급진적 기술이 등장함에 따라 해외 기술의 도입 위주로 진행되던 기술 전략?정책에 변화가 요구되고 있다. 이에 본 논문은 영화산업의 기술혁신에 초점을 두고 한국 영화산업의 기술혁신체제를 분석한다. 영화산업 관련 기존 문헌 분석과 전문가 인터뷰를 통해 한국 영화산업의 기술 및 지식, 제도, 혁신주체와 네트워크를 조망해 보며, 이를 통해 한국 영화산업 기술혁신체제의 특징과 문제점을 규명하는 것이 본 논문의 목적이다. 연구 결과 영화산업 기술혁신의 한국적 특징을 규명하였으며, 지식 축적 과정의 단절, 영화산업 특수적 연구 개발 활동의 부재, 혁신주체의 전문성 결여 등과 같은 문제점도 도출할 수 있었다. 이를 바탕으로 본 논문에서는 영화산업 기술혁신을 위한 정책적 함의를 제공한다. 또한 본 논문은 기술혁신연구 분야에 영화산업을 소개함으로써 새로운 연구 기회를 제공한다는 의의도 갖는다. Since the introduction of motion picture in the early 20th century, Korean motion picture industry has gradually evolved as one of the world leaders. However, due to the rapid technological change as exemplified by the emergence of the new digital and 3D cinema technologies, there is a need to re-consider the existing technology policy and strategy designed for the adoption and effective use of new technologies. In this paper, the authors address this issue by emphasizing the technological development side rather than the use/adoption side. In order to provide policy makers with critical information on the current status of the sector, we analyzed the sectoral innovation system of the Korean motion picture industry. In order to conduct this analysis, we re-visited previous literature and interviewed experts in the motion picture sector. Then, the authors attempted to identify the characteristics and problems of the current Korean motion picture industry. Based on the insights gained from this research, we draw policy implications for technological innovation in this sector. However, the implications from this paper are not limited to the motion picture industry. As the motion picture industry is a new case for innovation studies, our paper may provide new research opportunities to the academia.
