        대학의 플립드러닝에 요구되는 학습자 역량 진단 도구 개발 및 타당화 연구

        이유리,이유리,이소영 한국교육학회 2020 敎育學硏究 Vol.58 No.3

        Recently higher education has paid attention to flipped learning, which required the active participation of learners. Because the pre-class should be related to the post-class, instructors’ competency and role are essential in the flipped learning instructional design. Therefore by developing a measurement tool for university learners‘ competency about flip learning, we want to provide the instructor with learner information needed for designing a flipped class. The constructs which are to achieve class goals in the university’s flipped class successfully were selected, and 34 questionnaire items were constructed based on expert group review. A survey was conducted with 203 students in the flipped class. In addition, through exploratory factor analysis, items with low eigenvalue were removed, and 19 items were finally selected. Afterward, reliability analysis and confirmatory factor analysis were conducted on the final item to validate the test tool. In the reliability, convergence validity, and discriminant validity, the learners’ competency measurement tool’s validation was secured. It is expected that the validated flipped learning learner measurement tool for the university will be used as a means of providing primary data in instructional design, which will help learners who take flipped classes in university to conduct the learning objective successfully. 최근 대학교육 현장에서는 학습자의 능동적 참여를 수반하는 플립드러닝이 주목받고 있다. 플립드러닝은 사전 학습부터 사후 학습까지 맥락적 연계와 다양한 자료원 및 수업활동이 요구되므로 수업설계에서 학습자에 대한 정보가 필요하다. 이에 본 연구에서는 대학 수업환경에서 플립드러닝을 위한 대학생용 학습자 역량 진단 도구를 개발함으로써 교수자에게 플립드러닝 수업 설계에 필요한 학습자 정보를 제공하고자 한다. 먼저 대학의 플립드러닝 수업에서 수업 목표를 성공적으로 달성하는데 기여하는 구인을 선정하고전문가 집단의 검토를 바탕으로 34개의 설문 문항을 구성하였다. 플립드러닝 수업의 수강생 203명에게 설문조사를 실시하고 그 결과를 토대로 탐색적 요인분석을 실시하여 설명력이 낮은 문항을 제거하였다. 최종 선정된 19개 문항에 대해서는 신뢰도와 탐색적 요인분석 및 확인적 요인분석을 통해 신뢰도 및 구인타당도를 확인하였다. 타당화된 대학생용 플립드러닝에 대한 학습자 역량 진단 도구는 수업설계를 위한 기초자료로 활용되어 플립드러닝을 수강하는 대학생이 성공적인 결과에 도달하는데 도움이 될 것으로 기대된다.

        초등 무용교육공간에서의 ‘리듬분석’에 관한 이론적 탐색-앙리 르페브르 이론을 중심으로-

        이유리,박은규 학습자중심교과교육학회 2018 학습자중심교과교육연구 Vol.18 No.24

        The purpose of this study is to classify the categories of rhythm analysis in the elementary dance education space based on Henry Lefebvre 's theory and to clarify which rhythms interact with linear rhythm, circulation rhythm, harmonic rhythm and irregular rhythm in space, The goal is to find a theoretical approach. Most elementary learners spend a lot of time in the school space and experience a natural experience. This should not be overlooked as a process of being understood as a daily space and embodied in the body. Therefore, Lefebvre 's rhythm analysis can provide the rationale for expanding the constrained thinking about the space of elementary school and the narrow thought about the arts subject. It is pointed out that the transition process of human behavior should be removed from the institutional and normative implications and the recognition of space should be interpreted from various cultural perspectives. Furthermore, I expect that the constraint on the space can be seen as an attractive factor of rhythm and it will be the theoretical basis for seeking the teaching strategy of dance education. 본 연구는 앙리 르페브르 이론에 기반 하여 초등무용교육 공간에서 드러나는 리듬분석 범주를 구분하고 어떠한 리듬들이 공간에서 선형리듬, 순환리듬, 조화리듬, 부정리듬으로 상호작용하는 지를 밝히고 무용교수전략 구축에 있어 새로운 이론적 접근을 모색할 수 있는데 목적을 둔다. 대부분 초등학습자들이 학교공간에서 많은 시간을 할애하고 자연스러운 체험을 하게 되는데 이를 일상의 공간으로 이해하고 신체로 체화되는 과정임을 간과해서는 안 된다. 이에 Lefebvre의 리듬분석은 초등학교라는 공간에 대한 제약적인 사고와 예술교과에 대한 편협한 사고를 확장할 수 있는데 이론적 근거를 제시할 수 있다. 이는 인간의 행위가 전이되는 과정은 제도적, 규범적으로 주입되는 차원에서 벗어나야 하며 공간에 대한 인식 또한 다양한 문화적 관점에서 해석되어야 함을 지적하고 있다. 나아가 공간에 대한 제약을 리듬이라는 매력적인 요소로 현상을 드려다 볼 수 있으며 무용교육 교수전략 모색하는데 이론적 바탕이 될 것으로 기대한다.

        Effects of polydimethylsiloxane coating of Ni-MOF-74 on CH4 storage

        이유리,조성민,안화승 한국화학공학회 2018 Korean Journal of Chemical Engineering Vol.35 No.7

        Ni-MOF-74 was prepared by microwave heating and coated with polydimethylsiloxane (PDMS) via vapor deposition. Both the pristine and the PDMS-coated Ni-MOF-74 samples were exposed to moisture in air (relative humidity of 75%) for different periods of time, and their methane storage capacities under 35 bar conditions were measured. The pristine sample had a Brunauer-Emmett-Teller (SBET) surface area of 1,050m2·g1, with a CH4 uptake capacity of 113.8 mg·g1 at 300 K and 35 bar. After exposure to moisture for seven days, the BET surface area and CH4 uptake capacity declined drastically, whereas the PDMS-coated sample maintained its original BET surface area (1,018m2·g1) and CH4 uptake capacity (107.7mg·g1). After exposure to moisture in air for 30 days, however, even the PDMS-coated sample lost almost 60% of its CH4 storage capacity. All the methane storage capacity data were linearly correlated with the BET surface areas of the Ni-MOF 74 samples.

      • 5세기 고구려 고분벽화에서 나타난 집안-평양 간의 교류관계 연구: 옥도리 벽화고분을 중심으로

        이유리 미술사문화비평학회 2017 미술사문화비평 Vol.8 No.-

        고구려 고분벽화는 고구려인의 생활상과 그 시대의 역사와 문화가 고스란히 담겨 있는 자료이다. 특히 5세기 평양지역 고분벽화는 4세기 이래로 지속된 漢系와 낙랑 고분의 영향에서 점차 벗어나면서 평양천도 이후에는 고구려 고유의 문화가 반영된 벽화가 제작되기 시작하였다. 본 논문에서 옥도리 벽화고분에 주목한 이유는 바로 5세기 전 반~중반 평양지역에서 이루어진 집안지역 문화의 수용과 융합이 확인되기 때문이다. 옥도리 벽화고분이 조성된 5세기 고구려의 역사적 배경을 살펴보고 427년에 단행된 평양천도에 주목하였다. 수도 천도로 인해 평양은 이제 고구려의 새로운 정치적․문화 적 중심지로서의 역할을 하게 되었으며 이후 기존 국내성의 집안 문화가 새로운 수도 평양으로 유입되며 평양에서 汎고구려적인 새로운 문화가 꽃피게 되었다. 5세기의 고분 문화에서도 평양천도를 전후로 하여 두 지역의 고분문화가 교류․융합되는 과정을 거쳐 汎고구려의 문화가 성립됨을 확인할 수 있었다. 옥도리 벽화고분은 구조상 감실이 달린 二室墓의 구조로 평양지역 벽화고분 고유의 특징을 보여준다. 고분의 구조나 생활풍속·사신의 벽화 주제와 구성은 평양과 집안 지역의 고분들과 친연성을 보여 그 제작시기를 5세기 전반∼중반까지 내려다 볼 수 있다. 옥도리 벽화고분은 감이 달린 이실묘의 독특한 구조와 생활풍속·사신·장식문 등 다채로운 벽화 내용과 구성으로 주목받아 왔다. 또한 옥도리 벽화고분에 나타나는 집안과 평양지역 고분문화의 특징들은 고구려의 평양지역 지배 및 평양천도를 전후로 하여 두 지역에서 이루어졌을 문화적 교류를 보여준다. 그러나 옥도리 벽화고분은 두 지역의 고분문화가 공존할 뿐 아직 서로 융합하는 단계까지 나아가지는 못한 양상으로 두 지역 의 문화교류 초기 양상을 보여준다. 그러므로 옥도리 벽화고분을 통해 5세기 전반~중 반에 이루어졌을 두 지역 간의 교류를 통한 고분문화의 교류를 확인할 수 있으며, 옥도리 벽화고분은 5세기 후반 고구려 고분벽화와 汎고구려 문화의 탄생을 이해하는데 중요 한 단서를 제공해 준다. Goguryeo tomb murals are materials that contain Goguryeo people’s living conditions and the history and culture of the times intactly. Especially, the fifth-century tomb murals in the Pyeongyang area gradually got out of the influences of the Han dynasty and Nangnang tombs which had continued since the fourth century, and after the transfer of capital to Pyeongyang, murals reflecting Goguryeo’s own culture started to be produced. This thesis focused on Okdo-ri mural tombs because they show the acceptance and convergence with the culture of the Jian area in the early- to mid-fifth century Pyeongyang area. First, to analyze Okdo-ri tomb murals more in depth, this study looked into the origin and developmental process of iconographies by the theme through a comparison with other tombs. As a result, they succeed the characteristics of tomb murals in the Pyeongyang area, and usually showed many traces of exchange with the Jian area tomb culture. In addition, a possibility that the iconographies which have been defined as a custom of living previously can be seen as pictures with ritualistic characteristics through historical records, forms, compositions and comparison with other tombs was found. This study suggested a possibility in that the chronology of Okdo-ri mural tombs can be seen as the early- to mid-fifth century. In addition, this study focused on the transfer of capital to Pyeongyang, in 427 related to the development of the fifth century Goguryeo mural tombs built in Okdo-ri mural tombs. Because of the transfer of the capital, Pyeongyang came to act as a new political and cultural center of Goguryeo and after that, the existing Jian culture of Gungnae-seong flowed in new capital Pyeongyang, and a new culture of Goguryeo came into bloom in Pyeongyang. Judging that a new culture that covers the entire area of Goguryeo would be established also in the tomb culture, this study compared and summarized the details of tomb cultures around the transfer of capital to Pyeongyang. Okdo-ri mural tombs have attracted attention with their unique structure, colorful mural contents and compositions. Here, it is because the characteristics of Pyeongyang and Jian area tomb murals in Okdo-ri mural tombs show cultural exchange between two areas after the transfer of capital to Pyeongyang. Through Okdo-ri mural tombs, the convergence and development of tomb culture between two areas in the early- to mid-fifth century could be understood, and they have significance in that they show the birth of Goguryeo culture where elements of two areas were combined at the end of the fifth century.

        비알콜성 지방간질환의 한방치료에 대한 체계적 문헌고찰

        이유리,조나경,최홍식,김승모,김경순 대한한방내과학회 2019 大韓韓方內科學會誌 Vol.40 No.1

        Objectives: The purpose of this study was to assess the effects of Korean medicine for non-alcoholic fatty liver disease (NAFLD). We analyzed the result of randomized controlled trials (RCTs) that applied Korean medicine to NAFLD patients through meta analysis and systematic review. Methods: The key question was to the effects of Korean medicine for NAFLD patients according to the PICO-SD (participants, intervention, comparison, outcome, study design) and we included only RCTs. We searched 10 databases including NDSL, KMBASE, KISS, KISTI, KoreaMed, Koreantk, OASIS, Cochrane, Pubmed, EMBASE without a language restriction. We assessed risk of bias by Cochrane group's Risk of Bias tool. Results: The finally selected 12 RCTs were analyzed. Total number of participants was 1189 (male 719, female 470) as 684 and 505 in the oriental medicine group (i.e. herbal drugs, acupuncture, acupoint embedding therapy) and control group (conventional drugs, placebo), respectively. The meta analysis results of examining 7 RCTs comparing the therapeutic efficacy of herbal medicine with that of Western medicine showed statistically significant (p<0.05) differences in the efficacy evaluation, liver function test results, blood lipids, and TNF-α. Furthermore, the meta analysis results of investigating 3 RCTs comparing the therapeutic efficacy of herbal medicine with that of a placebo showed statistically significant (p<0.05) differences in the liver function test results, blood lipids, and waist circumference. Conclusions: The research showed that Korean medicine for NAFLD can be effective treatment. But more studies are required to enhance the level of evidence and we should report on safety.

        고혈당으로 유도된 제브라피쉬 당뇨망막병증 모델에서 약용식물의 효능 평가

        이유리,정승현,이익수,김주환,김영숙,김진숙 한국생약학회 2019 생약학회지 Vol.50 No.1

        The zebrafish (Danio rerio) is an established model organism for several pathophysiological conditions which are related to human diseases. In this study, we tested the preventive effect of eight herbal extracts, which show the inhibitory effect of advanced glycation end products (AGEs) or aldose reductase (AR) in our previous study, on high glucose (HG)-induced retinal vessel dilation in larval zebrafish and analyzed the change of hyaloid vasculature. HG-induced zebrafish hyaloid vasculatures were significantly increased in the thickness compared to untreated zebrafish (P<0.001, n=6~10). Eight herbal extracts were found to have significant retinal vessel dilation on the inhibitory activity. Particularly, Brandisia hancei (twigs and fruits), Castanopsis orthacantha (leaves and twigs), Litsea japonica (leaves and twigs), Spenceria ramalana (whole plant), and Synedrella nodiflora (leaves and stems) showed potent inhibitory activity against retinal vessel dilation in HG-induced larval zebrafish.

        한방병원에 입원한 환자 147명의 간기능 검사에 대한 후향적 관찰

        이유리,조나경,김경순,최홍식,김승모 한의병리학회 2018 동의생리병리학회지 Vol.32 No.6

        The purpose of this study was to evaluate the changes of liver function test before and after treatment in patients admitted to Korean medicine hospital. We checked liver function test level (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total bilirubin, direct bilirubin) of 147 patient who admitted in Korean medicine hospital from July 1, 2015 to June 30, 2018. The subjects were selected those who took herbal medicine continuously during the admission period and who performed liver function test on admission and before discharge. And the subjects were excluded those who had a history of liver and biliary disease at the time of admission or who took hepatoprotectants. Aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase significantly decreased compared with the values of admission(p<0.05), but total bilirubin and direct bilirubin were not significantly changed(p>0.05). On admission 31 patients(21.1%) had abnormal liver function and 6 patients(4.1%) had liver injury while 19 patients(12.9%) had abnormal liver function and 6 patients(4.1%) showed liver injury before discharge. This study suggests that herbal medicine may not injure liver function.
