As emission gas regulation of deisel vehicles is strengthened to Euro-6, It becomes difficult to deal with NOx regulated value mainly by EGR without additional after-treatment system. In addition, RDE(Real Driving Emissions) test will be introduced after september 2017. Therefore, It is essential to develop the after-treatment of diesel vehicles which reduce NOx emissions. It is possible to use DOC, DPF, LNT or DOC, DPF and SCR as a after-treatment system for reducing NOx. However, It is expected that the SCR will be applied widely because LNT alone does not have sufficient NOx purification efficiency. In this study, It tried to analyze the efficiency of reducing NOx emissions during the mode test by attaching a NOx sensor to test vehicle. As a result, It was confirmed that NOx emissions was significantly reduce through the after-treatment system from engine. And the NOx reduction efficiency of SCR was about 4.5 times better than DOC, DPF.

Emissions of diesel vehicles have been regulated by NEDC mode for a long time. However, the NEDC mode has been known the control of emission reduction is not reflected properly on actual road conditions. For these reasons, diesel vehicle emissions are regulated in both NEDC mode and WLTC mode from 2017 to 2020, from 2020 onwards, the emissions of diesel vehicles will measure in WLTC mode only and will not be able to exceed 1.5 times the regulated value. The purpose of this study is to analyze the development trend of diesel vehicle after-treatment system in order to comply with the future regulations on diesel vehicle. As a result, it is essential to reduce the NOx emissions of diesel vehicles for Euro 6, the NOx emissions of the test vehicle equipped with SCR were 30% to 50% loss than the test vehicle equipped with LNT despite the higher curb weight and engine displacement.

The waste from beer fermentation broth (WBFB) has been found an excellent and inexpensive resource for bioethanol production. We tried to evaluate the saccharification and fermentation capabilities of WBFB to confirm its effectiveness for bioethanol production. The saccharification potentials of the WBFB were evaluated at various temperatures (30, 40, 50, 60and 70 ℃). It was found that the saccharification capabilities increased with temperature and highest reached maximum at 60 ℃ and 70 ℃ after 4h. Ethanol production from a mixture of WBFB and chemically defined media (CDM) without addition of any microbial species confirmed the fermentation capabilities of WBFB. Simultaneous saccharification and fermentation were performed using WBFB, starch solution and CDM as culturing media. The maximum yield of bioethanol production was obtained at 30 ℃. The saccharifying enzymes and the yeast cells present in WBFB were essential factors for the production of bioethanol from WBFB without any additional enzymes or microbial cells.

설명적 텍스트 쓰기 양상 분석을 통한 쓰기 윤리 교육 내용 탐색

강민경 ( Min Gyeong Kang ) 국어교육학회 2011 國語敎育學硏究 Vol.42 No.-

쓰기 윤리 교육의 목표는 ``윤리적으로 글을 쓰는 것``이다. 그러나 쓰기 윤리에 대한 규범의 강조, 쓰기 규범의 내면화, 규제의 강화만으로 이러한 목표가 달성되기는 어렵다. 쓰기 윤리는 일종의 규범이지만, 윤리적으로 글을 쓰기 위해서는 쓰기 능력이 필수적이기 때문이다. 따라서 쓰기 윤리에 대한 내용을 독립적으로 다루기보다는, 쓰기의 실제와 통합하여 쓰기 과정에서 윤리적인 문제를 해결하기 위한 지식과 기능을 지도할 것을 제안하였다. 본고에서는 설명적 텍스트 쓰기에서 쓰기 윤리 문제가 어떻게 드러나는지, 그러한 문제를 해결하기 위해서는 어떠한 교육 내용이 필요한지에 대해 탐색하였다. 쓰기 과제는 ``참고 자료를 활용하여 소개하는 글 쓰기``이다. 참고 자료는 두 가지 유형―출력본과 하이퍼텍스트-으로 제시하였다. 학생들의 쓰기 과정을 녹화한 동영상, 학생이 작성한 글을 분석하였으며, 두 가지 표절 검색 프로그램을 활용하여 표절 정도에 따라 어떠한 특성이 나타나는지 살펴보았다. 분석 결과를 바탕으로 ``설명적 텍스트 윤리적으로 쓰기``에 대한 교육 내용을 ``지식``, ``기능``으로 구성하였다. The typical solutions to ethics of writing` problem are strengthening ethics of writing and tightening regulations on plagiarism. But in the middle or high school, the objective of teaching ``ethics of writing`` is that students can write ethically. So the effective solution to the problem of ethical writing is to integrate ``ethics of writing`` as a kind of ``standards`` with writing process as a kind of ``practice``. This paper aims to concretize ``writing expository text ethically``. I analysed student`s writing process and products. And I used two plagiarism detection programs to describe the characteristics of writing process according to degree of plagiarism. As the students wrote expository text from sources, their compositions were similar in text structure, contents, and expressions. But some students tried to avoid plagiarism by using some strategies-classification, summarizing, defining, adding contents. On the basis of these analysis, I organized writing knowledge and writing strategies to help students to write expository text ethically.

외래 도서가 한국한문학의 발전에 끼친 영향의 탐색 『태평광기(太平廣記)』의 국내 유입과 그 영향-유선시(遊仙詩)를 중심으로-

강민경 ( Min Kyoung Kang ) 동방한문학회 2016 東方漢文學 Vol.0 No.66

『Taip`ingkuangchi(太平廣記)』, which contains an extensive narrative aroused intellectual interest to domestic intellectuals. 『Taip`ingkuangchi』 was accepted positively in terms of broadening the knowledge. In particular, 『Taip`ing-kuangchi』 had translation, so it could achieve as well as the expansion of the common people and to women readership hierarchy. 『Taip`ingkuangchi』 had played an important role in the development of Korea by offering the classic novel materials and new techniques of creative fiction literature in the country. But 『Taip`ingkuangchi』 was likely to affect a wide range of Korean Chinese poetry. Many poetry authors were taking advantage of a person or event featured in the 『Taip`ingkuangchi』 as customary. Poets were strongly attracted the height of the 『Taip`ingkuangchi』 in wriying poetry process. Especially the author of Yusun literature had an enormous influence of 『Taip`ingkuangchi』. They used 『Taip`ingkuangchi』`s words in the part of the work or full. They also wrote created the book report format. Among 『Taip`ingkuangchi』, they used the hermits and women hermits of 『Taip`ingkuangchi』`s front. In this context, Heo Nanseolheon(許蘭雪軒)`s Yusun poetry needs to be approached carefully again in association with 『Taip`ingkuangchi』. If we understand fully the background of poetry, we will be able to feel more accurately nanseolheon`s Yusun poetry. In particular, the background of reading 『Taip`ingkuangchi』 - which was regarded as heresy - was understood as well knowledgeable persons, Tongyu(通儒). 『Taip`ingkuangchi』 that was recorded as novel of the sea, has vast and diverse narratives, so it might help to equip the erudition and to broaden the knowledge of Confucian scholars. 『Taip`ingkuangchi』 has the theme of retribution, contains strange and interesting stories were attractive factors for a Confucian scholars. Especially hermit stories gave a surrogate satisfaction for the reader who wanted to escape from the cramped reality. So artists dreamed to fly freely away from the reality of redemption through writing hermit`s wold. 『Taip`ingkuangchi』 helped people who were accustomed to the system and order to remind the value of freedom and to be able to dream.
