이신동(Lee Shin Dong),원재권(Won Jae Gourn),김기명(Kim Ki Myoung) 한국영재교육학회 2007 영재와 영재교육 Vol.6 No.2

본 연구는 Kolb의 4가지 학습유형에 따라 초등학교 수학영재, 과학영재, 일반 학생의 학습유형을 비교해 보고, 학습유형에 따라 교수방법 선호도가 어떻게 달라지는지 확인하기 위한 것이다. 이를 위해 지역교육청 2곳의 영재교육원 초등학교 수학ㆍ과학영재 학생 각60명, 일반 학생은 초등학교 2곳의 6학년 120명 총 240명을 연구 대상으로 하였으며, 이들의 학습유형검사ㆍ교수방법선호도 검사의 자료를 수집ㆍ분석하였다. 검사도구로는 Kolb(1999)의 학습유형검사(LSI), Renzulli, Rizza, & Smith(2002)의 교수방법 선호도 측정 검사지를 활용하였다. 본 연구의 결과 수학영재 학생과 과학영재학생의 학습유형은 차이가 없었으나 영재학생과 일반학생의 학습유형에는 차이가 있었으며, 동화적 학습자 유형을 제외한 발산적 학습자, 수렴적 학습자, 조절적 학습자 유형은 고유하게 선호하는 교수방법들을 가지고 있었다. 또한 수학영재 학생과 일반학생은 학습유형에 따른 교수방법 선호도에 차이가 없었으나, 과학영재 학생은 학습유형에 따fms 교수방법 선호도가 다르게 나타났다. 이런 결과는 영재학생과 일반학생의 학습유형이 서로 다르고 그에 따른 교수방법도 다르다는 것을 나타낸다. 따라서 교실수업을 담당하는 교사들은 학생들의 학습유형에 맞는 교수방법을 제공하여 교수적합성을 달성함과 동시에 교수 효과를 극대화하기 위해서 각각의 학습유형과 교수방법에 대한 충분한 이해가 선행되어야 할 것이다. The purpose of this study is to compare the learning styles of the mathematics gifted, the science gifted, and general students at elementary schools by Kolb"s four learning styles, and ascertain how the preference of instructional methods become different by learning style. To achieve the purpose in this study, the four propositions were set as follows: First, what differences exist among the mathematics gifted, the science gifted and general students in terms of learning style? Second, what differences exist in terms of the preference of instructional methods by learning style among the mathematics gifted, the science gifted, and general students? To solve the abovementioned propositions, this study targeted 60 elementary school-level mathematics gifted students, 60 science gifted students at gifted students education institutes, and 120 six graders at Elementary School: this study targeted a total of 240 students. For the learning style test used in this study, ""Learning Style Inventory (LSI),"" which originally presented by Kolb in 1976, but was revised anew in 1999, and was translated by Lee, Shin-dong (2005), was used. As a test to measure the preference of instructional methods, ""Measure of Student Preference for Instructional Techniques,"" developed by Renzulli, Rizza, and Smith (2002), and translated by Lee Shin-dong (2005) was used. The confidence levels of the tests were good, respectively. The analysis of the collected test responses was tested through a confidence analysis, technical statistics, MANOVA, and Sheffe test was used for follow up test. The SPSS 12.0 Program was used for the analysis. The analytical results of the collected data are presented as follows: Firstly, there was no difference in the learning style of the mathematics gifted and the science gifted, but there was difference in the learning style of the gifted and general students. Secondly, it was identified that divergent learners, convergent learners, regulated learners, except for assimilative learners, had their preferred instructional methods. Thirdly, there was no difference in the preference of instructional methods by learning style and gender between the mathematics gifted and general students. The science gifted students had different preference of instructional methods by learning style, but they did not show any difference on the preference of instructional methods by gender. In conclusion, the divergent learners and convergent learners are judged to be more active in learning activities and have higher learning motivation. Teachers taking charge of classroom teaching should provide instructional methods in line with such learning styles so as to achieve the adequacy of instruction, and draw maximum instructional effects. Those teachers also need to pay more attention to enhancing learning motivation of the relatively passive regulated learners and assimilative learners.

Trophic importance of meiofauna to polychaetes in a seagrass (Zostera marina) bed as traced by stable isotopes

Ha, Sun-Yong,Min, Won-Ki,Kim, Dong-Sung,Shin, Kyung-Hoon Cambridge University Press [etc.] 2014 Journal of the Marine Biological Association of th Vol.94 No.1

<P> Stable carbon and nitrogen isotope ratios of benthic invertebrates and their potential food sources, such as suspended particulate organic matter (POM), benthic microalgae, attached algae and seagrass, were identified in Dong-dae Bay during the winter. The carbon stable isotope ratios demonstrate that filter feeders, such as oysters (?19.5 ± 1.0‰), use benthic microalgae (?21.2 ± 0.2‰) as a major food, and polychaetes such as Glycera spp. (?14.0 ± 0.6 ‰) preferentially use meiofauna, such as nematodes (?14.0 ± 0.4‰) and copepods (?13.3 ± 1.0‰). These meiofauna may feed on mixed resources (including bacteria) with the isotope ratios between benthic microalgae (?21.2 ± 0.2‰) and seagrass (?9.3 ± 01.0‰). These findings are consistent with the trophic enrichment in the nitrogen isotope ratios (by 3?4‰) between consumers and food sources. Moreover, the results of the MixSIR model based on the observed isotope ratios suggest a large seagrass contribution to the food sources of benthic organisms such as meiofauna (~53.7?62.6%) and macrobenthos (~41.1?68%) through the food web. This model additionally suggests a relatively large contribution of benthic microalgae to the food sources of filter feeders (i.e. 26.4% for oysters). </P>

김동찬 ( Dong Chan Kim ),김신원 ( Shin Won Kim ),김미래 ( Mi Rae Kim ) 한국전통조경학회 2012 한국전통조경학회지 Vol.30 No.2

본 연구는 북촌의 가로 중에서도 특히 한옥밀집지역인 가회동을 중심으로 가로경관에 대한 이론적 고찰과 북촌 가로경관의 대한 시각적 특성에 따른 선호도의 상관관계를 밝히고자 하였다. 이에 북촌의 가장 대표적인 경관 삼청동 35번지, 가회동 31번지, 11번지를 대상으로 가로경관의 시각량과 선호도의 관계를 기술분석하였다. 또한 요인분석을 통하여 북촌가로경관의 이미지 특성의 공통요인을 추출하였고, 회귀분석을 실시하여 이미지평가와 선호도간의 관계를 파악하였다. 이에 따른 연구결과로는 첫째, 시각량과 선호도 관계에서 가회동 31번지의 가로경관이 가장 선호도가 높게 나타났으며, 북촌가로경관의 천장면과 식재의 시각량이 높을수록 높은 선호를 보이고 있었다. 둘째, 심리적인 측면에서는 북촌의 가로경관은 ``심미성``, ``쾌적성``, ``정연성``의 특성으로 설명되었으며, 가장 선호가 높게 나온 가회동 31번지와 낮게 나온 삼청동 35번지는 ``심미성`` 항목에서 많은 차이를 나타내고 있었다. 셋째, 심리변수 요인에 대한 요인점수와 선호도에 대해 회귀분석을 실시한 결과, ``심미성``을 설명하는 인자가 선호도에 가장 많은 영향을 미치고 있는 것으로 나타났다. 이에 따라 전체 경관과 조화를 이루어 지역적인 특성을 잘 살린 이용자가 만족할 수 있는 북촌의 가로 정비 방안이 체계적으로 발전되어야 할 것으로 판단된다. This study aimed to research theoretical reviews of streetscape and to analysis the correlation between visual properties and preference of streetscape in Bukchon around Gahoe-dong which is a dense Hanok area. Therefore we analyzed a relation between visual quantities and preference intended Samcheong-dong 35 street, Gahoe-dong 31 street and Gahoe-dong 11 street the representative streetscape in Bukchon. Also we extracted common factors of images of the streetscape in Bukchon and figured out a relation between the visual image evaluation and the preference by regression analysis. The result of the analysis is as follows. First, it was the streetscape of Gahoe-dong 31street which get more scores than any other streetscape in preference. And we figured out that the higher the ceiling and the visual quantities of planting the more preference. Second, streetscape in Bukchon was explained by ``aesthetics``, ``amenity`` and ``orderliness`` in psychological view. And there was noticeable difference in aesthetics aspect between Gahoe-dong 31 street the highest preferred place and the Samcheong-dong 35 street the lowest preferred place. Third, as a result of regression analysis on preference and factor scores about psychological variables, we figured out that the factor which explains aesthetics effects most on the preference.

Dong Yeok Shin,이원섭,Seok Hyun Kim,Min Jeong Kim,Jeong Won Yun,Jing Nan Lu,Sung Joong Lee,Irina Tsoy,김혜정,류충호,Gi Young Kim,강호성,신성철,Yung Hyun Choi 한국식품영양과학회 2009 Journal of medicinal food Vol.12 No.5

We investigated anti-invasive effects of the anthocyanins from fruits of Vitis coignetiae Pulliat (known as meoru in Korea) on human hepatoma Hep3B cells. The anthocyanins inhibited cell invasion in a dose-dependent manner as measured by Matrigel™ (BD Biosciences, San Jose, CA, USA) invasion assays. They also inhibited expression of matrix metalloproteinase (MMP)-2 and MMP-9 and activation of nuclear factor κB (NF-κB) stimulated by tumor necrosis factor α. Taken together, the results of this study indicate that the anthocyanins isolated from fruits of V. coignetiae Pulliat have anti-invasive effects on human hepatoma Hep3B cells and inhibit MMP-2 and MMP-9 gene expression at least in part through the inhibition of NF-κB activation.

Background/Aims: During viral infection, tissue damage is caused not only by direct cytopathic effects of virus but also by host immune responses. We investigated activation status and functions of CD8+ T cells and the mechanism of CD8+ T cell-mediated host injury in acute hepatitis A (AHA), which is caused by hepatitis A virus (HAV) infection and manifested by severe liver injury in adults. Methods: The study population was AHA-diagnosed 56 patients, hospitalized in Chung-Ang University Hospital. All patients were seropositive for anti-HAV IgM and had clinical and laboratory features of acute hepatitis. The whole blood and serum were obtained, and peripheral blood mononuclear cells were isolated by Ficoll density-gradient centrifugation and cryopreserved. Direct ex vivo IFN-γ ELISpot assay of peripheral blood lymphocytes was performed by stimulating them with overlapping peptides for HAV VP2 and 3C proteins in order to assess comprehensively HAV-specific IFN-γ response. Results: Total IFN-γ response against VP2 and 3C did not show positive correlation to serum ALT level, corroborating that the liver injury of AHA is not associated with HAV-specific T cell response. Activation of unrelated virus-specific CD8+ T cells significantly correlated with the percentage of CD38+HLA-DR+ cells in total CD8+ T cells, which was a correlate of the liver injury. In a prospective analysis, the percentage of CD38+ HLA-DR+ cells in total CD8+ T cells or that in unrelated virusspecific CD8+ T cells decreased along with the decrease in serum ALT level at the time of discharge, but that in HAVspecific CD8+ T cell population did not. Conclusions: We demonstrate that unrelated virus-specific CD8+ T cells, which are not specific to HAV, are activated and proliferating in AHA, the severity of liver injury correlates with the activation of non-HAV-specific CD8+ T cells, not to that of HAV-specific T cells.

Dong Young Hwang,InJi Heo,Ji Won Jang,Seo jin Moon,SeulKi Kim,Young Seo Hong,Tae Young Shin 한국응용곤충학회 2024 한국응용곤충학회 학술대회논문집 Vol.2024 No.04

Mycoviruses are a group of viruses that infect filamentous fungi. While most hosts infected with mycoviruses do not show any symptoms. In some cases, mycoviruses induce various phenotypic changes include alterations in morphology, drug resistance, pathogenicity, virulence, sporulation, and growth. Entomopathogenic fungi are one of the integrated pest management agents as an alternative to conventional insecticides. Mycoviruses have the potential as supportive agents, enhancing the efficiency of the insecticidal activity of the fungi. Studies about mycoviruses themselves and their interaction with their hosts, especially entomopathogenic fungi, are needed to realize their full potential. In this work, the sequence of the dsRNA element isolated from the entomopathogenic fungus Metarhizium pinghaense 4-2 strain was determined. Through this study, we report the sequence of a dsRNA virus isolated from the Metarhizium pinghaense for the first time. In further studies, the ORF of the mycovirus that induces a phenotype change in the host will be researched.

A Study on Using U-Service to Strengthen Urban Competitiveness

Shin, Jin-Dong,Lee, Jae-Won,Lee, Sang-Hun,Kim, Hyong-Bok Korea Spatial Information Society 2009 한국공간정보학회지 Vol.17 No.4

본 연구에서는 유시티의 U-서비스와 도시경쟁력 평가지표의 상호 연관성을 찾고 있다. 연구결과 U-서비스가 빈도에 차이를 보이지만 6개의 도시유형별로 도시경쟁력 강화 수단으로 활용되고 있다. 특히 안전 건강, 활력(경제)도시형에서 적절한 U-서비스 활용은 도시경쟁력 강화에 기여할 수 있는 빈도가 높다. 다음으로 도시경쟁력 평가항목 중 공동항목과 문화도시형에서는 U-서비스가 도시경쟁력 강화에 상대적 기여도가 낮다. 이는 도시의 정책을 평가하는 항목으로 구성되어 있는 공동항목이 도시의 물리적 시설 지능화를 통해 U-서비스를 구현하는 유시티 성격에 부합되지 않는 것이다. 반면 문화도시형과 관련된 U-서비스는 상대적으로 서비스개발이 미약하기 때문이다. 본 연구를 통해 U-서비스는 도시 경쟁력 강화에 활용될 수 있음을 확인할 수 있었다. This study examined correlations between U-Service for U-City and assessment indicators for urban competitiveness. The results of this study show that U-Service is used as a means of strengthening urban competitiveness in six types of cities, despite the differences in degree of contribution. The proper use of U-Service in Safety & Health City and Vitality (Economy) City has significantly contributed to strengthening the competitiveness of such cities. Of the assessment items for urban competitiveness, common items and Culture City type show that U-Service has not contributed much to strengthening urban competitiveness. The analysis shows that because common items are part of the assessment items for urban policies, these items are not suitable to the character of a U-City that implements U-Service through intelligent physical facilities. On the other hand, U-Service related to the Culture City type is relatively less developed. This study found out that U-Service could be used to reinforce urban competitiveness.
