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.

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.

도교적 상상력의 현대적 활용 가능성 고찰

강민경(Kang Min-kyoung) 한국도교문화학회 2008 道敎文化硏究 Vol.28 No.-

본고는 타자의 위치를 벗어나지 못했던 도교의 현대적 활용 가능성을 모색하기 위해 마고할미를 다루었다. 마고는 중국에서는 여신 혹은 여선이었다. 신성성과 숭고함을 지녔던 마고는 우리나라로 들어와 거인 할미가 된다. 견고한 가부장적 제도는 여성으로서 신성성과 초월적 능력을 가진 마고 할미를 거부한 것이다. 마고할미의 권위는 깎이고, 마고할미의 신이한 능력은 제 구실을 못하고 웃음거리로 전락하고 말았다. 그러나 오늘날, 포스트 모던 사회의 도래와 더불어 마고할미는 다시 부활하기 시작했다. 마고할미 이야기는 동화와 연극, 뮤지컬, 영화, 음악 등 여러 분야에서 다양한 콘텐츠로 활용되고 있다. 문학과 예술을 막론하고 모든 작품에서 마고할미는 거인신이자 천지창조의 여신으로 표현되었다. 마고할미가 다시 살아난 이유를 살펴보면 첫째, 중세기에 부정적으로 인식된 여성성이 오늘날엔 따뜻하고 부드러운 속성으로 긍정되고 있다. 둘째, 마고할미의 신이한 능력과 자유분방한 행동은 오늘날의 환상과 연결된다. 셋째, 마고할미가 만든 세상은 도교가 추구하는 이상향의 모습과 닮아 있다. 오늘날은 상상력이 지식의 원천이고 힘이 되는 시대다. 따라서 동양 문화의 뿌리인 도교적 상상력을 복원하여 문화콘텐츠의 풍부한 원천을 제공해야 할 것이다. This study treated Mago grandma to seek A possibility of practical application in Taoistic imagination. Taoism couldn't get out of the marginal location. Mago was a goddess or a female hermit in China. Mago with the sanctity and the sublime was changed to a giant. A patriarchal system rejected Mago grandma because she was a female with the sanctity and transcendental power. Mago grandma's authority was disgraced and her ability degenerated into a laughingstock. But Nowadays, with a coming of post-modern society, Mago grandma was started to resurrect. The story of Mago grandma is used as various contents in juvenile stories, theater, musical dramas, music, films, dancings. Without distinction of literature or art, Mago grandma was expressed as a giantic goddess and the Creator. Why did Mago grandma resurrect? The reasons are as follows. First, the character of female that was regarded as negative one is affirmed for broad-mindedness and gentle-heart. Second, Mago grandma's ability and liberal acts are connected the present fantasy. Third, Mago grandma's world resembles the Utopia in Taoism. Now imagination is the source of knowledge and power. Therefore the resurrect of Taoistic imagination can be the source of cultural contents.

본 연구는 2015 개정 교육과정에서 고등학교 선택 과목으로 신설된 ‘언어와 매체’의 평가 방안을 모색하기 위한 기초 연구이다. 연구의 목적은 대학수학능력시험 등과 같은 국가 수준에서의 평가 상황을 전제로 하여 2015 개정 교육과정 적용으로 인해 처음 실시되는 ‘매체’ 영역의 평가에 대비하는 것이다. 이를 위해 2015 개정 국어과 교육과정, 국어과 교육과정 관련 연구, 검정 교과서 등을 분석하여 국가 수준에서의 ‘언어와 매체’ 과목 평가, 특히 ‘매체’ 영역과 관련된 평가에서 예상되는 쟁점을 도출하였다. 2015 개정 교육과정 분석을 통해서는 과목의 성격, 내용 체계 및 학습 범위, 성취기준에 대한 해석과 관련된 쟁점을 도출하였으며, 교과서에 대한 1, 2차 분석을 통해 내용 영역별로 예상되는 쟁점을 분석하였다. 본 연구는 ‘언어와 매체’ 과목에서 타당도 확보와 선택 과목 간유불리 문제 방지라는 평가상의 난제에 대한 논의의 출발점이라는 점에서 의의가 있다. This study is basic research into assessment for the subject, Language & Media, which was newly created as a high school elective in the 2015 revised national curriculum. The study aims to investigate assessment for the Media area of Language & Media for a national-level test such as the College Scholastic Ability Test, not for the fundamental and ideal assessment of the media literacy for classroom assessment. To this end, the researcher analyzed the 2015 revised Korean Language National Curriculum and investigated literature on the Korean Language Curriculum and five high school textbooks to determine what issues, particularly in the area of Media, could potentially arise when Language & Media was implemented in a national-level test. From the analysis of the 2015 revised curriculum, issues related to the characteristics of the subject, the content system and learning elements, and the interpretation of achievement standards were identified as potential issues. Through analyses of five textbooks, the possible issues according to each content area were discussed. This study is meaningful in that it is a starting point for discussion on the challenges in relation to securing validity and maintaining equality between elective subjects in national-level testing.

보 설치가 퇴적물 특성에 미치는 영향에 관한 연구

본 연구에서는 보의 설치가 하천 퇴적물에 미치는 영향을 알아보고자 남한강 하류에 설치된 강천보, 여주보, 이포보에 대하여 보의 영향을 잘 대표할 수 있다고 생각되는 9개 지점을 선정해 퇴적물 분석을 진행하였다. 채취한 퇴적물의 물리적, 화학적 특성을 분석하기 위해 입도, 함수율, 완전연소가능량, COD, TOC, TP, SRP, TN 항목을 선정하여 분석하였다. 분석결과 퇴적물의 입도 분포는 전 구간에 걸쳐 같은 Sandy loam의 토양분류를 나타내어 준설이 퇴적물의 입도 분포에 영향을 주었다고 판단된다. 입도, 함수율, 완전연소가능량, COD, TOC, TP, SRP, TN 항목에서 보 설치지점의 상류 농도가 하류보다 높게 나타나는 것으로 보아 남한강 하류 유역에 설치된 보가 퇴적물 흐름에 영향을 미쳐 보의 상부에 퇴적양상을 나타내었다고 생각한다. 하지만 SRP 및 C/N 비율 분석 결과에서는 지역에 따른 퇴적물 특성의 차이가 크지 않고, 퇴적물의 유기물 기원 분석의 경우에는 과거 퇴적물의 특성이 나타나는 점으로부터 연구가 수행된 시점에서는 보의 설치가 퇴적물의 특성에 미치는 영향이 크지 않다고 판단된다. 하지만, 남한강 수계에 설치된 보는 강우에 의해 외부에서 유입되는 토사의 이동 및 퇴적에 영향을 줄 수 있고, 이는 수층으로의 오염물질의 확산 및 재부유를 발생시켜 수질 및 수생태계에 영향을 미칠 수 있으므로 보 설치구간 퇴적물의 물리적 화학적 특성 변화에 대한 지속적인 모니터링이 필요하다고 생각한다. To investigate the effects of weir construction on sediment characteristics of river bed, we conducted sediments sampling on the 9 locations near the weir, Kangchun, Yuju and Ipo in Namhan-River. Physical and chemical characteristics of sediments were analyzed by measuring particle size distribution, water content, Ignition loss, COD (Chemical Oxyzen Demand), TOC (Total Organic Carbon), TP (Total Phosphorus), SRP (Soluble Reactive Phosphorus) and TN (Total Nitrogen). Particle classification of all three weir sediments showed sandy loam that was caused by the river bed dredging. Due to the presence of weir, Ignition loss, COD, TOC, TP, SRP and TN showed similar trend such as the concentrations of upward weir had higher than those of downward weir. For the case of SRP concentration and C/N ratio, however, there is not much difference in the sediment characteristics compared to the those of sediments before weir construction. Therefore, It can be predicted that there are little effects of weir construction on sediment characteristics. However, weir construction could influence water quality of the river by controlling the transport and the accumulation of suspended materials from rainfall. Therefore, more intensive monitoring is required to examine the magnitude and patterns of sediment accumulation which could influence overlying water quality.

고려 지배층의 신라 출자의식과 그 사회적 성격

강민경(Kang Min-kyeong) 한국역사연구회 2019 역사와 현실 Vol.- No.112

After the fall of Silla(新羅), the royalty and nobility of Silla were resettled in Kaegyeong(開京) and became the bureaucrats of Goryeo(高麗) or remained in Gyeongju(慶州). Their status was classified by their strengths, while being raised and dropped depending on political and social changes. Of course, they were claim to able the “Silla origin consciousness(新羅 出自意識)”. the cultural influence of Silla, which traditionally descended, did not disappear. But, until the 11th century, the ruling class of Goryeo did not boast much of their ancestors, so it was quite rare for the descendants of Silla to reveal it. In the 12th century, the Silla origin consciousness began to attract attention from some ruling class of Goryeo who used Silla-style family name. It was a result of a combination of self-identity as a clan(門閥) who settled in Goryeo. Such movements were possible because there were the households of the Silla royal or noble families that led to the clan. However, this was the only means of decorating himself by emphasizing that his genealogy that to Shila’s royalty or nobility, and it was expressed by a part of the clan. After the late 12th century, Silla origin consciousness could still be the pride of the bureaucracy over the generations. But, in the 13th and 14th centuries, the new generation of bureaucrats also showed a connection to the ancestor of Silla. This was in accordance with the needs of the ruling class. At that time, there were a great change in the Goryeo class society such as the entry of people with lower status into central political arena. Then, introduction of neo-confucianism has affected many of that phenomenon. It is important to point out the fact that some ruling class was descendants of Silla over almost the entire period of Goryeo were purely due to the needs of the Goryeo rulers. Soon, “Silla origin consciousness” was a means to establish self-identity as Goryeo rulers. However, even though a man who was a high official in Goryeo was actually an ancestor of Silla, he was not a real Silla person. He is a Goryeo person.
