북한의 외국인 대상 조선어교육 운영 실태 분석 연구-김일성종합대학교 연수자의 경험을 중심으로-

The purpose of this study is to examine the Korean language education curriculum for foreigners in North Korea. We focused on interviews with Chinese international students who participated in the ‘Chosun Exchange Scholarship Program’ from April to October 2016 at Kim Il-sung University. To this end, two written interviews and three in-depth interviews were conducted to secure the validity and reliability of the study. Through interviews, it was found that in 2016, a total of 35 foreigners received Korean language education at Kim Il-sung University. In addition, it was found that the Korean language education curriculum for foreigners in North Korea is divided into 'Korean language education as a foreign language' and 'general Korean language education'. Compared to the Korean language curriculum as a foreign language, it was found that the general Korean language education curriculum had about two hours more class time per week and the number of subjects was also four more. Also, the textbooks used in the general Korean language education curriculum were different from the textbooks in the Korean language curriculum as a foreign language. However, the observation activities were carried out in the same way as the Korean language curriculum as a foreign language, and through this, the system propaganda effect was being promoted. Lectures were mainly centered on teachers, and achievement evaluation was conducted once at the end of the term. The interviewer evaluated that this experience in North Korea had a positive influence on interviewer’s career choice. (Yonsei University)

학위 논문 감사의 글 장르분석 연구 -중국인과 한국인의 텍스트 비교를 중심으로-

The purpose of this study is to identify the differences between the two groups through genre analysis on the articles of dissertation acknowledgements that appeared in the thesis of Chinese and Koreans. To this end, research was conducted on master’s and doctoral thesis altogether 80 related to Korean language education. Specifically, the composition patterns of the two groups’ dissertation acknowledgements were examined, and the ‘moves’ measures and ‘steps’ composition of each text were analyzed. Besides, we looked at the differences in the rhetorical structure. According to the analysis results, there was no significant difference overall in the text composition patterns of the two groups, and similar results were also shown in the appearance of move nodes and steps. However, at the level of the steps, there was a significant difference in the frequency of ‘reflecting’ and ‘providing resources and helping technical support’ as the Chinese’s international student status was reflected. Also, at the step of ‘Blessing’, both groups were able to confirm the common cultural perception of the Eastern world by composing texts with forward-looking speech actions, and it is also known that Koreans list in detail the objects to express their appreciation compared to Chinese. This study is meaningful in that it examines differences in writing between Chinese and Koreans, targeting the writings of dissertation acknowledgements that have not been well handled so far.

키토산의 항균활성에 미치는 염화나트륨 및 유기산의 영향
홍의범 ( Yi Fan Hong ),김한근 ( Hangeun Kim ),방면호 ( Myun Ho Bang ),김현수 ( Hyun Su Kim ),김태락 ( Tae Rack Kim ),박윤희 ( Yun Hee Park ),정대균 ( Dae Kyun Chung ) 한국미생물생명공학회(구 한국산업미생물학회) 2014 한국미생물·생명공학회지 Vol.42 No.4
식품용 방부제로써의 가능성을 평가하기 위하여 염화나트륨, 아세트산, 젖산, 구연산이 포함된 배지를 사용하여 대장균 및 황색포도 상구균에 대한 키토산의 항균성을 조사하였다. 키토산의 억제활성은 100 ppm의 키토산(분자량 3,000)이 포함된 배양배지에 염화나트륨을 첨가시킴으로써 미세하게 감소하였다. 반면, 아세트산, 젖산, 구연산 등은 세균의 성장에 대한 키토산의 억제활성을 증가시켰다. 이러한 결과는 염화나트륨, 아세트산, 젖산, 구연산과 같은 식품 첨가 성분이 키토산의 항균활성에 심각한 영향을 미칠 수 있다는 것을 보여준다. The antibacterial activity of chitosan against Escherichia coli and Staphylococcus aureus was investigated in the presence of NaCl, acetic acid, lactic acid, and citric acid to assess its potential use as a food preservative. The inhibitory activity of chitosan decreased slightly upon adding NaCl to culture broth containing 100 ppm of chitosan (MW 3,000), while adding acetic acid, lactic acid, or citric acid enhanced the inhibitory activity of chitosan on growing cells. Our results indicate that food components, such as NaCl, acetic acid, lactic acid, and citric acid, can significantly affect the bactericidal activity of chitosan.

구조물의 6자유도 변위 측정을 위한 비주얼 서보잉 기반 양립형 구조 광 로봇 시스템
전해민(Haemin Jeon),방유석(Yuseok Bang),김한근(Hangeun Kim),명현(Hyun Myung) 제어로봇시스템학회 2011 제어·로봇·시스템학회 논문지 Vol.17 No.10
This study aims to demonstrate the feasibility of a visual servoing-based paired structured light (SL) robot for estimating structural displacement under various external loads. The former paired SL robot, which was proposed in the previous study, was composed of two screens facing with each other, each with one or two lasers and a camera. It was found that the paired SL robot could estimate the translational and rotational displacement each in 3-DOF with high accuracy and low cost. However, the measurable range is fairly limited due to the limited screen size. In this paper, therefore, a visual servoing-based 2-DOF manipulator which controls the pose of lasers is introduced. By controlling the positions of the projected laser points to be on the screen, the proposed robot can estimate the displacement regardless of the screen size. We performed various simulations and experimental tests to verify the performance of the newly proposed robot. The results show that the proposed system overcomes the range limitation of the former system and it can be utilized to accurately estimate the structural displacement.
