일본어학부에서의 『일본어알고리즘』 IT융합교과 운영을 통한 학부경쟁력 강화 사례 연구
조치영 일본어문학회 2019 일본어문학 Vol.86 No.-
本論文では、日本語学部で行われている教科目のうち「日本語アルゴリズム」の具体的な運営事例と効果について提示している。これはIT工学分野だけではなく、一般事務職の環境にまで影響が及び始めた。このような社会的な雰囲気で日本語を専攻している学生達が卒業し、無事に社会に進出できるように日本語学部にIT融合の専攻過程の計画を立てて2009年から本格的に運営している。本研究は、このようなIT融合教科目である「日本語アルゴリズム」の運営事例である。 本学部の日本IT進出のための学生教育はコンピューター言語教育を基盤として、上級問題の解決能力を養う「日本語アルゴリズム」で完成する。この科目は日本のIT企業の業務で欠かせない物であり、学生達が日本で中長期的に適応するため非常に重要である。本研究では、「日本語アルゴリズム」科目の運営内容と日本語学部内の融複合の教科目間の連携を示し、日本語学部が自立でIT融複合教育を実施する計画がある教育機関の参考資料になれるように努力した。 This is a case study on IT convergence education implemented in the Japanese department to widen the doors to entry into Japan. For this, we have taught students algorithm so that they can cultivate the high‐level problem solving skills. Algorithms are so essential a subject for Japanese IT business that the students can be made to adjust in Japan for a mid and long‐term job security. This study shows the contents of Japanese Algorithm curriculum and inter‐curricular linkage in the Japanese department. We have tried to make the Japanese department the reference for the institutes which have the plans to carry out the IT education for entry into Japan. This algorithm curriculum is proven to be an important role and this study describes the contents and administration of algorithm studies in detail. In addition, this is considered the tool that enhances the competitiveness of the Japanese department.

In this paper, the growing orientation of PMN-PT single crystal is analyzed using the Laue-Back Reflection Method. Two kinds of PMN-PT single crystals are grown using the Bridgman growing method in the [001] and [111] directions and their the Laue photographs are simulated assuming cubic crystal systems. From the comparison between simulation and test results, it can be concluded that the single crystals are grown in the desired crystal orientations.

조치영 한국언어과학회 2015 언어과학 Vol.22 No.2
By supporting of internet and development of computer system such as high-end tablet PC equipped a camera, network system, and network personal video recorder, there have been recently new approaches using computers in language education, which of them is e-Tandem system. The purpose of this study is to propose a method to make e-Tandem systems more efficient and a prototype to be a model for development of e-Tandem S/W. In this study, a new e-Tandem system based on the recognition of pattern will be presented to improve existing e-Tandem systems so that language learning might be more effective. This paper proposes a kind of e-Tandem system and its application for efficient English education. In other words, e-Tandem equipped with face detection and voice recognition can heighten the education effect. This study shows that this proposal can overcome the limits of time and space and that it is a feasible e-Tandem system employing current engineering by experiment.

압전 세라믹의 재료 정수 규명의 일반적인 방댄은 어떤 형상과 분극 방향을 가진 진동체의 동특성을 이용하는 것이다. 본 논문에서는 압전 세라리의 복소 재료 정수극 규명하는 방법을 제시하였다. 이 방법은 이론적인 이미턴스 값과 실험으로 측정된 값과의 오차가 최소화 되도록 하는 비선형 최적화 기법을 사용하여 손실이 고려된 복소 압전 재료 정수를 규명하는 것이다. 재료 정수 규명을 위하여 이미턴스(Immittance)를 공진 주파수 근처와 저주파 영역을 포함하여 측정한 값을 동시에 활용하였다. 본 논문에서 제안된 방법을 검증하기 위해 PZT4 세라믹의 복소 재료 정수를 실험적으로 규명하였다. The common practice for the identification of piezoelectric properties is based on the use of immittance of a resonator with a certain geometry and poling direction. In this paper, a new method is suggested to identify the complex-valued piezoelectric material constants. This method Is based on the minimization of differences between the analytical immittance and the experimental measurement of resonator. Non-linear minimization problems are formulated to find out the unknown properties relevant to the resonators. The immittance data used for identification are measured at a number of frequencies which cover the vicinity of resonance frequency and the low frequency region. To illustrate the proposed technique, the complex-valued coefficients are identified for a typical PZT4 ceramic composition.
조명 변화에 강인한 얼굴 검출을 위한 좌우대칭 평균화 기법

형판 정합 기반의 얼굴 검출 시스템에서 획득된 이미지에 대한 명암 정규화 및 영상 보정을 위해 히스토그램 평활화나 로그 변환 등을 사용한다. 이 방법은 조명 변화에 의해 발생한 이미지의 부분 명암 왜곡에는 효과적이지 못하다는 것이 알려져 있다. 본 논문에서는 부분적 명암 왜곡에 매우 효과적인 영상 보정을 수행하는 좌우대칭 평균화 기법을 제시한다. 실험 결과 이 기법은 기존의 방식보다 매우 효율적인 검출 성능을 보일 뿐만 아니라 얼굴 후보의 개수도 현저하게 감소하는 것으로 나타났다. In a face detection system based on template matching, histogram equalization or log transform is applied to an input image for the intensity normalization and the image improvement. It is known that they are noneffective in improving an image with intensity distortion by illumination variation. In this paper, we propose an efficient image improvement method called as a bilateral symmetry average for images with intensity distortion by illumination variation. Experimental results show that our method delivers the detection performance better than previous methods and also remarkably reduces the number of face candidates.
