This study aims to examine the preferences with regard to multimedia materials displayed by Korean university students, in accordance to the Myers-Briggs Type Indicator (MBTI). MBTI is a psychometric questionnaire designed to evaluate four areas of psychological preferences, including: how people are energized; how people perceive the world; how people make decisions and how people arrive at conclusions. The study focused upon 676 students, for the duration of a fifteen week period while they were attending English classes. The purpose of the study was dual. Firstly, students’ character types were examined via the Myers’ typological personality assessment. Secondly, the correlation between their personality traits and preferences towards certain multimedia materials was investigated. The results of the study indicated that students possessing certain personality characteristics, demonstrated an individual preference relating to specific multimedia material. The study suggested extroverted personality types displayed a preference for off-line activities, therefore limiting the scope of multimedia materials amongst this group of individuals. However, the investigation indicated that students of an introverted disposition preferred online activities, therefore increasing the effect multimedia materials could exhibit upon their English learning. The study also examines the pedagogical implications of the research results and highlights the limitations of the data.

최영임,Choi, Young-Im 한국문헌정보학회 2017 한국문헌정보학회지 Vol.51 No.3

본 연구의 목적은 고등학교 학교생활기록부 독서활동 기록에 대한 인식을 조사하고, 분석된 자료를 토대로 학교생활기록부 독서활동 기록 개선 방안을 모색하는 것이다. 이를 위해 고등학생 120명을 대상으로 자료를 수집하고 분석하였다. 연구 결과를 종합해보면 '독서활동상황' 기록에 대한 만족도, 독서활동 기록의 필요성, 독서활동 기록 방법 등에서 부정적인 반응이 나타났다. 고등학생들의 독서활동이 활성화되기 위해서는 현재 기록 방법을 개선할 필요가 있다. 학생들이 독서를 통해 성장한 내용을 도서명으로는 확인할 수 없기 때문에 성장과정을 이해할 수 있는 다양한 독후활동 기록, 교과교사와의 상호작용 활동 등을 기록하는 방법으로 개선할 필요가 있다. 본 연구가 대학의 학생부종합전형에서 독서평가 방법의 변화와 학교 현장의 바람직한 독서문화에 큰 역할을 할 것을 기대한다. The purpose of this study is to investigate the perception of records for reading activities in high schools and to make a suggestion for improvement of reading activities records. Data for 120 high school students were collected and analyzed for this study. This study showed negative response results in terms of the satisfaction of the 'reading activity situation' record, the necessity of the reading activity record, and the method of recording the reading activity. It is, however, necessary to improve the current recording method to invigorate high school students' reading activities. Since it is not easy to identify students' development in reading by the titles which they provides for the reading activity records, a variety of reading activities need to be recorded for understanding students' development process and interaction activities with teachers. It is expected that the findings in this study will be significant data to improve evaluation methods of reading activities for college admission and to cultivate proper reading culture in high schools.

배은경,최영임,이효신,최지원,Bae, Eun-Kyung,Choi, Young-Im,Lee, Hyoshin,Choi, Ji Won 한국식물생명공학회 2019 식물생명공학회지 Vol.46 No.3

옥신은 식물의 생장과 발달 과정에서 중요한 조절자로서 기능한다. 옥신 신호전달 과정은 3개의 주요 옥신 반응 전사인자인 Auxin/indole-3-acetic acid (Aux/IAA), Gretchen Hagen 3 (GH3), 그리고 small auxin up RNA (SAUR) 유전자에 의해 조절된다. 특히, Aux/IAA는 옥신 신호에 반응하여 빠르게 축적되는 수명이 짧은 핵 단백질이다. 이 실험에서 우리는 현사시 나무(Populus alba ${\times}$ P. glandulosa)로 부터 PagAux/IAA1 유전자를 분리하고 발현 특성을 분석하였다. PagAux/IAA1 cDNA는 4개의 보존된 도메인과 2개의 nuclear localization sequence (NLS)을 포함한 200개의 아미노산을 암호화하고 있다. Southern blot 분석으로 현사시나무 genome에 PagAux/IAA1 유전자가 single copy로 존재하는 것을 확인하였다. PagAux/IAA1 유전자는 잎과 꽃에서 특이적으로 발현되었다. 그리고 PagAux/IAA1 유전자는 현탁배양세포의 생장 과정에서 초기 지수생장기에 발현되었다. PagAux/IAA1 유전자의 발현을 분석한 결과, 건조와 염 스트레스 및 식물호르몬인 ABA 처리에 의해 발현이 감소된 반면 저온 스트레스, 형성층의 세포 분열 과정 그리고 식물호르몬인 GA와 JA 처리에서 발현이 증가하였다. 따라서 PagAux/IAA1 유전자가 현사시나무에서 저온 스트레스 반응뿐 아니라 생장 과정에 관여할 것으로 판단된다. Auxin plays a crucial regulatory role in plant growth and development processes. Three major classes of auxin-responsive transcription factors controlled by the Auxin/indole-3-acetic acid (Aux/IAA), Gretchen Hagen 3 (GH3), and small auxin up RNA (SAUR) genes regulate auxin signaling. Aux/IAA, in particular, encodes short-lived nuclear proteins that accumulate rapidly in response to auxin signaling. In this study, we isolated a PagAux/IAA1 gene from poplar (Populus alba ${\times}$ P. glandulosa) and investigated its expression characteristics. The PagAux/IAA1 cDNA codes for putative 200 amino acids polypeptide containing four conserved domains and two nuclear localization signals (NLSs). Utilizing Southern blot analysis, we confirmed that a single copy of the PagAux/IAA1 gene was present in the poplar genome. The expression of this gene is specific to leaves and flowers of the poplar. PagAux/IAA1 expressed in the early exponential growth phase of cell-cultured in suspension. PagAux/IAA1 expression level reduced in drought and salt stress conditions, and the presence of plant hormones such as abscisic acid. However, expression enhanced in cold stress, cambial cell division, and presence of plant hormones such as gibberellic acid and jasmonic acid. Thus, these results suggest that PagAux/IAA1 participates in cold stress response as well as developmental processes in the poplar.

In this study, we report the generation and analysis of 1,392 expressed sequence tags (ESTs) from Korean Stewartia (Stewartia koreana Nakai). A cDNA library was generated from the young leaf tissue and a total of 1,392 cDNA were partially sequenced. EST and unigene sequence quality were determined by computational filtering, manual review, and BLAST analyses. Finally, 1,301 ESTs were acquired after the removal of the vector sequence and filtering over a minimum length 100 nucleotides. A total of 893 unigene, consisting of 150 contigs and 743 singletons, was identified after assembling. Also, we identified 95 new microsatellite-containing sequences from the unigenes and classified the structure according to their repeat unit. According to homology search with BLASTX against the NCBI database, 65% of ESTs were homologous with known function and 11.6% of ESTs were matched with putative or unknown function. The remaining 23.2% of ESTs showed no significant similarity to any protein sequences found in the public database. Annotation based searches against multiple databases including wine grape and populus sequences helped to identify putative functions of ESTs and unigenes. Gene ontology (GO) classification showed that the most abundant GO terms were transport, nucleotide binding, plastid, in terms biological process, molecular function and cellular component, respectively. The sequence data will be used to characterize potential roles of new genes in Stewartia and provided for the useful tools as a genetic resource.

현사시나무 Gibberellic Acid-Stimulated Arabidopsis (GASA) 유전자의 발현 특성 및 건조 스트레스 내성 구명

최현모,배은경,최영임,윤서경,이효신,Choi, Hyunmo,Bae, Eun-Kyung,Choi, Young-Im,Yoon, Seo-Kyung,Lee, Hyoshin 한국식물생명공학회 2017 식물생명공학회지 Vol.44 No.1

GASA는 GA에 의해 조절되는 식물 유전자로서, 여러 식물에 보존되어 있고 다양한 조직에서 식물의 생장과 발달 및 스트레스 반응에 관여하는 것으로 알려져 있다. 본 연구에서는 GASA 유전자를 현사시나무(Populus alba ${\times}$ P. glandulosa)에서 분리하여 이를 PagGASA라 명명하고, 유전자의 구조와 발현특성을 조사하였다. PagGASA 유전자는 95개의 아미노산으로 구성된 단백질을 암호화하며, 아미노 말단에 시그널 펩티드 영역과 카르복시 말단에 12개 시스테인 잔기가 보존되어 있다. PagGASA는 현사시나무의 염색체에 1 ~ 2 copy 존재하며, 꽃과 뿌리에서 높게 발현하였다. 또한 PagGASA는 GA 뿐 아니라 ABA와 JA, SA와 같은 스트레스 관련 식물 호르몬의 처리에 의해서 발현이 증가하는 것으로 나타났다. 현사시나무에 형질전환하여 PagGASA를 과발현시킨 결과 건조 내성에 효과가 있음을 확인하였다. 따라서 PagGASA는 스트레스 관련 식물 호르몬 신호전달과 연결되어 건조 스트레스 방어기작에서 중요한 역할을 할 것으로 생각된다. Gibberellic Acid-Stimulated Arabidopsis (GASA) genes are involved in plant hormone signaling, cell division and elongation, as well as in responses to stress conditions in plants. In this study, we isolated a GASA gene from hybrid poplar (Populus alba ${\times}$ P. glandulosa) and analyzed its physiological phenotype and molecular functions in poplar. PagGASA cDNA encodes a putative protein composed of 95 amino acids containing an N-terminal signal peptide and a conservative cysteine-rich C-terminal domain. Southern blot analysis revealed that one or two copies of the PagGASA are present in the poplar genome. The PagGASA transcripts were highly detected in flowers and roots. Moreover, the expression of PagGASA was induced by growth hormone (gibberellic acid) and stress hormones (abscisic acid, jasmonic acid, and salicylic acid). By using transgenic analysis, we showed that the upregulation of PagGASA in poplar provides high tolerance to drought stress. Therefore, our results suggest that PagGASA plays an important role in drought stress tolerance via stress-related plant hormone signaling in poplar.

현사시나무에서 MYC2 유전자의 분리 및 노화 지연에 관한 특성 구명

최현모,배은경,조진성,이효신,최영임,Choi, Hyunmo,Bae, Eun-Kyung,Cho, Jin Seong,Lee, Hyoshin,Choi, Young-Im 한국식물생명공학회 2017 식물생명공학회지 Vol.44 No.4

The vegetation period of trees might be prolonged by the delay of the leaf senescence in autumn. Thus, we focused on the generation of senescence-delayed transgenic trees to enhance biomass production. The PagMYC2, a gene containing the basic helix-loop-helix domain, was selected as a candidate for a senescence-delayed transgenic tree. The PagMYC2 gene was specifically induced after treatment with phytohormone jasmonic acid, and upregulated by abiotic stresses such as salinity, osmotic pressure and a low temperature. The constitutive overexpression of the PagMYC2 delayed the leaf senescence and inhibited chlorophyll degradation in the transgenic poplars. Leaf senescence analysis was performed in the leaf tissues of the PagMYC2-over-expression transgenic poplars. The transgenic poplars exhibited higher photochemical efficiency than did a wild type plant under a short-day condition (6 hours light/18 hours darkness) or a low temperature condition ($15^{\circ}C$) that was similar to the weather conditions of autumn. These results suggest that the PagMYC2 is a useful genetic resource to improve biomass production, which is able to sustain growth with senescence-delayed leaves for a long time in autumn. JA는 병원균과 곤충에 대한 방어기작 뿐만 아니라 식물 노화에도 관여하는 식물 호르몬이다. Basic helix-loop-helix 전사인자인 MYC2는 JA의 신호전달반응의 핵심조절자 역할을 하는 것으로 알려져 있다. 본 연구에서는 현사시나무에서 MYC2 유전자를 분리하고 발현특성을 조사하였으며, 다양한 환경 스트레스에 대한 내성을 갖는 임목을 생산하기 위하여 MYC2를 과발현시킨 현사시나무를 개발하였다. 포트에 식재된 MYC2 과발현 현사시나무는 대조구에 비해 잎 노화 표현형이 지연되는 특징을 보였으며, 엽록소 손실이 적은 것으로 나타났다. 또한 가을의 온도 및 광 주기 조건에서 MYC2 과발현 현사시나무의 광화학 효율을 측정한 결과 대조구보다 높은 특징을 보였다. 따라서 현사시나무의 MYC2 유전자가 낙엽이 지는 가을 동안에도 지속적인 생장을 가능하게 하여 임목의 바이오매스를 증진시키는데 기여할 수 있을 것으로 판단된다.
