구석기시대 설치류 화석과 고환경 : 정선 매둔 동굴유적을 중심으로

박지효(Jihyo Park) 한국구석기학회 2021 한국구석기학보 Vol.- No.43

강원도 정선군 남면 낙동리에 위치한 매둔 동굴유적은 연세대학교박물관에 의해 2016년부터 현재까지 발굴조사가 진행되고 있는 곳이다. 약 3m의 퇴적층에서 구석기·신석기·청동기시대에서부터 근·현대까지 이르는 다양한 유물과 동물화석 등이 확인되었다. 특히 동물화석 분석에서는 대형포유류 동물상에 대한 연구는 진행되었으나, 소형포유류 화석은 체계적으로 다루어지지 못하였다. 이러한 이유로 인해 매둔 동굴유적에서 수습된 소형포유류에 주목하였으며, 이 가운데 고환경 복원에 유용한 설치류 화석을 분석대상으로 하였다. 학위논문에서는 구석기·신석기·청동기층 설치류 화석을 전반적으로 관찰하였으나 본 글에서는 2구획의 구석기층 출토 화석을 중점적으로 살펴보았다. 2구획 구석기층에서 확인된 설치류 화석은 총 2과 10속 13종으로 구성되어 있으며 최대뼈대수(NISP)를 토대로 한 최소마리수(MNI)는 약 34마리로 산출되었다. 세부 층위별로 나누어 보면 구석기 1층(P-1)에서는 2과 8속 10종(최소마리수 18마리), 구석기 2층(P-2)에서는 2과 7속 9종(최소마리수 16마리)의 설치류 화석이 확인되었다. 이러한 종적 구성을 해석하기 위하여 설치류 종별 생태유형 및 한반도 내 설치류 화석 출토 유적을 정리하였다. 분석 결과, 매둔 동굴 유적 구석기층의 설치류 동물상은 북한의 황주 청파대 동굴 및 한국의 제천 점말용굴과 가장 유사한 것으로 나타났다. 또한 다양한 종 가운데 산쥐, 간단이빨쥐, 라티셉갈밭쥐 등을 통해 퇴적층 형성 당시 유적 주변이 현재보다 서늘하고 건조한 기후였음을 알 수 있다. 그러나 특정한 서식환경에 대한 제약 없이 대부분의 환경에 잘 적응하는 등줄쥐, 비단털들쥐 등이 같이 출토하기 때문에 설치류 종적 구성은 ‘생태학적 다양성’을 반영하는 것으로 해석된다. This study attempted at analysis of paleolithic rodent fossils and paleoenvironment using fossils from Maedun cave site in Jeongseon, Korea. Excavation led by the Yonsei University Museum is still underway in Maedun cave site located at Nakdong-ri, Nam-myeon, Jeongseon-gun, Gangwon-do Province since 2016. A variety of relics were identified on about three-meter sedimentary layers Maedun cave site in which people had long inhabited and settled from the Paleolitic·Neolithic·Bronze Age to the modern time. In particular, a study on macro-mammal fauna was settled into shape but, unfortunately micro-mammal fauna were not systematically observed and further analyzed. In this light, this article analyzed rodent fossils good for paleoenvironmental reconstruction among micro-mammals gathered at this cave site. In spite of observing and analyzing all of rodent fossils unearthed from Paleolitic·Neolithic·Bronze Age layer in master’s monograph, I have observed rodent fossils excavedted from Paleolithic layer in ‘Second section’ closely. As a result, the number of rodent fossils at the Maedun cave site’s paleolithic level revealed that there were a total of 71. And that fossils were classified into 2 families 10 genera and 13 species. Also the Number of Identified Specimens(NISP) and the Minimum Number of Individuals(MNI) were calculated based on the species composition. The species composition of Paleolithic-1 layer turned out 2 familes 8 genera 10 species (MNI: 34 consisting of 18), and 2 familes 7 genera 9 species (MNI: 34 consisting of 16) in Paleolithic-2 layer. In order to comprehend composition of rodent fossils, each rodent’s ecological type and the excavtion list of fossils founded in the Korean Peninsula was organized. Maedun cave site’s rodent fauna was similar with Cheongpadae cave site(North Korea) and Jeommal cave site(South Korea). Furthermore, representative rodent fossils in the Paleolithic layer pertaining to the Quaternary-Pleistocene Period include Alticola, Pitymys simplicidens and Microtus ratticeps from which it can be said that there had been cold and dry weather in the time when sedimentary layers were formed. However, it can be explained that the species composition was reflected on ‘ecological diversity’ account for unearthing Apodemus and Eothenomys regulus which adapted themselves to any natural environment.

In the case of Korea, the reason why the public is very interested in the education system related to the university entrance exam is that the university entrance exam is evaluated as a big factor influencing life, such as those who graduated from prestigious universities occupying a superior position in society in terms of employment. On the other hand, in Canada, the university entrance policy is not discussed in the public debate. This is because the goal of Canadian school education is to strengthen students’ competencies and vocational training for social advancement. Therefore, in this study, the characteristics of Canada’s education system and university entrance examination were examined, and through this study, the implications for the improvement of our university entrance examination system were investigated. This study emphasizes the universality of Korea’s university education as in the case of Canada at a national quality level.

In this study, Korean immigrants' participation in ethnic religious institutions was examined within the multilingual context of Montreal, Canada in order to understand the role of ethnic community institutions for Korean immigrant parents’ attitudes toward their younger generations’ Korean language and cultural identity preservation. The present study focuses particularly on the parent participants’ attitudes toward their children’s majority languages (i.e., English & French) and Korean language learning in general, and on their attitudes toward the role of the religious ethnic institution in their lives, particularly related to the linguistic and cultural responsibility of the church for Korean immigrants. In this study, total 23 Korean immigrant parents participated. All of them live in the Montreal area and actively participate in a Korean immigrant church. For this study, qualitative interviewing and participant observation were conducted. Interviews were conducted only in Korean for less than one hour on the average. Observations were conducted in the church where all the participants attended for a five-week of period in 2019. Field notes were taken in full detail during the observation period for analysis. Overall, the findings of this study confirm the socio- cultural and linguistic role of ethnic religious institutions for Koreans abroad, and also for their integration to the multicultural society.

(Purpose) One of the goals of learning English as a foreign language (EFL) is to communicate properly but EFL anxiety has been found to be one of obstacles to EFL learning. Since listening and speaking language are interactive processes, listening anxiety is possibly related to speaking anxiety, resulting in poor performance when learning English. Moreover, as language is used as a communicative tool, anxiety in social interaction might have an effect on EFL anxiety. The purpose of this study, thus, was to examine whether and how social anxiety and interpersonal orientation were associated with English listening and speaking anxiety. (Design/methodology/approach) 94 freshmen who enrolled in college English classes participated in the survey of this study. We used a Foreign Language Listening Anxiety Scale to measure English listening anxiety and Public Speaking Class Anxiety Scale to measure English speaking anxiety. In addition, Social Avoidance Distress Scale was used to measure social anxiety and Fundamental Interpersonal Relation Orientation-Behavior short version was used to measure interpersonal orientation of EFL learners. (Findings) This study has shown that social anxiety was strongly associated with English speaking anxiety and the relationship between social anxiety and English speaking anxiety was mediated by English listening anxiety. Moreover, interpersonal orientation moderated the relationship between social anxiety and English speaking anxiety. It was shown that the learners with a high interpersonal orientation showed high English speaking anxiety even though their social anxiety was low. (Research implications or Originality) The findings of this study imply that it is important to reduce social anxiety when learning English because social anxiety is strongly related to English listening and speaking anxiety. Furthermore, since individual characteristics such as interpersonal orientation also has an effect on anxiety when learning English, characteristics of learners should be considered. Since Virtual Reality(VR) systems could be useful in considering learner’s attributes as well as reduce anxiety, we suggest that it is necessary to develop a VR environment for learning a foreign language(FL).

<P>Analysis of protein dynamics using single-molecule fluorescence resonance energy transfer (smFRET) is widely used to understand the structure and function of proteins. Nonetheless, site-specific labeling of proteins with a pair of donor and acceptor dyes still remains a challenge. Here we present a general and facile method for site-specific dual labeling of proteins by incorporating two different, readily available, unnatural amino acids (<I>p</I>-acetylphenylalanine and alkynyllysine) for smFRET. We used newly evolved alkynyllysine-specific aminoacyl-tRNA synthetase/tRNA<SUB>UCA</SUB> and <I>p</I>-acetylphenylalanyl-tRNA synthetase/tRNA<SUB>CUA</SUB>. The utility of our approach was demonstrated by analyzing the conformational change of dual-labeled calmodulin using smFRET measurements. The present labeling approach is devoid of major limitations in conventional cysteine-based labeling. Therefore, our method will significantly increase the repertoire of proteins available for FRET study and expand our ability to explore more complicated molecular dynamics.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ancham/2013/ancham.2013.85.issue-3/ac303089v/production/images/medium/ac-2012-03089v_0008.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ac303089v'>ACS Electronic Supporting Info</A></P>

신재생에너지 전력의 지불의사액 추정모형 연구

김지효(Kim, Jihyo),박주영(Park, Jooyoung),김해연(Kim, Haeyeon),허은녕(Heo, Eunnyeong) 한국신재생에너지학회 2010 한국신재생에너지학회 학술대회논문집 Vol.2010 No.06

우리나라는 제 3차 신재생에너지 기술개발 및 이용 보급 기본계획을 통해 2030년까지 111.5조 원을 투자하여 전체 에너지의 11%를 신재생에너지로 공급한다는 목표를 설정하였다. 그러나 신재생에너지는 기존의 원자력이나 화석에너지에 비하여 생산비용이 높아 보조나 융자 등의 정부지원에 의존하여 보급이 이루어져왔다. 신재생에너지 보급확대 및 산업발전을 위한 보급정책의 일환으로 정부는 2012년부터 RPS(Renewable Portfolio Standard, 신재생에너지 공급의 무화제도)를 도입키로 확정하였다. RPS의 도입은 일정규모 신재생에너지 시장수요를 창출함과 동시에 신재생에너지원간 가격경쟁 구도 형성의 유인이 될 수 있다. 이는 전력가격 일괄상승 및 녹색가격제도(Green Pricing) 등의 정책적 논의로 이어질 수 있다. 따라서 소비자 측면에서 신재생에너지 전력의 가치를 어떻게 평가하는지를 분석하여 RPS 시행제반의 정책적 논의의 기초자료를 마련할 필요가 있다. 특히 RPS는 신재생에너지원 간의 경쟁을 가능하게 하므로 개별 신재생에너지원에 따라 소비자 선호의 차이가 어떻게 나타나는지 연구되어야 한다. 이에 본 연구는 환경재 혹은 비시장재화의 가치추정에 가장 널리 활용되고 있는 조건부가치평가법(Contingent Valuation Method; CVM)을 적용하여 풍력, 태양광, 수력으로 생산한 전력에 대한 소비자의 지불의사액(Willingness to Pay; WTP)을 분석하는 모형을 수립하였다. 이를 위해 Zografakis et al.(2010), Yoo and Kwak(2009), 이창훈 황석준(2009), Nomura and Akai(2004), Bately et al.(2001) 등의 선행연구를 참조하여 신재생에너지 전력 가치의 설문에서 고려되어야 하는 요인들을 선정하였다. 이를 토대로 설문 시나리오를 작성하여 각 요인들이 신재생에너지 전력에 대한 지불의사액 결정에 어떠한 영향을 미치는지 분석가능한 모형을 설정하였다. 뿐만 아니라 기존 연구들이 신재생에너지로 생산된 일반적인 전력에 대한 지불의사액을 질문하는데 그쳤다면, 본 연구에서는 각 원별로 지불의사액의 차이를 도출할 수 있는 설문모형을 구축하는데 중점을 두었다. 본 연구결과는 향후 설문수행을 통하여 신재생에너지원별로 소비자의 선호를 분석할 수 있는 연구로 발전될 수 있으며, 이는 RPS 도입으로 인한 전력가격 정책 수립의 기초 연구자료로 활용될 수 있다 하겠다.
