정영미 한국항공경영학회 2023 한국항공경영학회지 Vol.21 No.5

코로나 팬데믹으로 전 세계가 사상 초유의 비상사태를 겪으며 교육 현장은 혼란 속에서 어려움에 직면하였다. 특히 일반 교육기관에서 쉽게 접할 수 없었던 비대면 수업으로 교육과정을 운영하면서 학생들의 자기주도학습(self-directed learning)에 대한 중요성이 더욱 높아졌다. 교육부가 2022년 교육과정 개정을 앞두고 창의력, 인성, 자기주도성을 미래 사회의 핵심 인재 역량으로 제시하였다. 또한 코로나 팬데믹과 4차 산업혁명으로 교육 환경이 급격히 변화하고 있으며 미래 사회로 나아가기 위한 학습자의 역량을 강화하는 방안이 요구되고 있다. 특히 코로나 엔데믹으로 항공산업도 재도약을 준비하며 지식, 정보, 기술을 바탕으로 스스로 지식을 창조하는 능력을 갖춘 인재가 요구된다. 새로운 변화의 자각은 학습자 스스로 학습에 책임을 지고 학습을 주도하는 자기주도학습능력이 주목받고 있다. 자기주도학습은 타인의 도움 없이 스스로 학습 목표를 설정하고 학습 실행 및 결과를 평가하는 과정을 의미하며 21세기 평생학습 시대에 갖추어야 할 핵심역량이라 할 수 있다. 이러한 점에서 자기주도학습능력을 향상시키기 위한 구체적 방안을 검토하고 자기주도학습에 영향을 주는 변인에 대한 연구의 필요성이 대두되고 있다. 본 연구에서는 항공관광전공 대학생들을 대상으로 성장마인드셋, 그릿과 자기주도학습능력 간의 영향 관계와 그릿의 매개효과를 검증하고자 한다. 연구대상은 충남소재 H대학교 항공관광전공 대학생 219명을 대상으로 하였으며, 통계분석은 SPSS 25.0을 활용하였다. 분석결과는 첫째, 항공관광전공 대학생의 지능-성장마인드셋과 성격-성장마인드셋이 그릿의 구성요소 관심의 일관성과 노력의 꾸준함에 유의미한 정(+)의 영향을 미치는 것으로 나타났다. 둘째, 항공관광전공 대학생의 지능-성장마인드셋과 성격-성장마인드셋이 자기주도학습능력의 구성요인 인지적 능력, 정의적 능력, 행동적 능력에 유의미한 정(+)의 영향을 미치는 것으로 나타났다. 셋쩨, 항공관광전공 대학생의 그릿 관심의 일관성과 노력의 꾸준함은 자기주도학습능력 구성요인 인지적 능력, 정의적 능력, 행동적 능력에 유의미한 정(+)의 영향을 미치는 것으로 나타났다. 넷째, 항공관광전공 대학생의 성장마인드셋이 자기주도학습능력에 미치는 영향에서 그릿의 매개효과는 성장마인드셋과 자기주도학습능력의 인지적 능력, 정의적 능력, 행동적 능력에서 그릿 관심의 일관성은 부분매개하는 것으로 나타났다. 또한 성장마인드셋과 자기주도학습능력의 인지적 능력에서 그릿 노력의 꾸준함은 부분매개하는 것으로 나타났다. 성격-성장마인드셋과 자기주도학습능력의 정의적 능력과 행동적 능력에서는 그릿 노력의 꾸준함은 부분매개하고, 지능-성장마인드셋과 자기주도학습능력의 정의적 능력과 행동적 능력에서 그릿 노력의 꾸준함은 완전매개하는 것으로 나타났다. 본 연구 결과는 항공관광전공 대학생의 자기주도학습능력에 그릿을 매개로 성장마이드셋이 긍정적인 영향을 미치는 것을 알 수 있다. 따라서 항공관광전공 대학생의 자기주도학습능력 제고를 위해 성장마인드셋과 그릿에 대한 이해를 바탕으로 교육과정 운영과 교수법 활용이 요구된다. As the world experienced an unprecedented emergency due to the COVID-19 pandemic, the education field faced difficulties amidst chaos. In particular, the importance of students’ self-directed learning has increased as the curriculum is operated as non-face-to-face classes that are not easily accessible in general educational institutions. Ahead of the curriculum reorganization in 2022, the Ministry of Education has proposed creativity, character, and self-direction as key talents in the future society. In addition, as the educational environment is rapidly changing due to the COVID-19 pandemic and the 4th industrial revolution, measures to strengthen learners’ capabilities are required to advance into the future society. Awareness of new changes is drawing attention to the ability of self-directed learning in which learners take responsibility for learning and lead learning. Especially as the aviation industry prepares for a leap forward due to the coronavirus endemic, talent with the ability to create knowledge on their own based on knowledge, information, and technology is required. Self-directed learning refers to the process of setting learning goals and evaluating learning practices and results without the help of others. It can be said that it is a core competency to be equipped in the era of lifelong learning in the 21st century. In this regard, the necessity of reviewing specific measures to improve self-directed learning ability and researching variables that affect self-directed learning is emerging. This study aims to verify the relationship between growth mindset, grit and self-directed learning ability and the mediating effect of grit for college students majoring in aviation tourism. The subjects of the study were 219 university students majoring in aviation tourism at H University in Chungnam, and SPSS 25.0 was used for statistical analysis. As a result of the analysis, first, it was found that the intelligence-growth mindset and personality-growth mindset of college students majoring in aviation tourism had a significant positive (+) effect on the consistency of interest and persistence of effort. Second, it was found that the intelligence-growth mindset and personality- growth mindset of college students majoring in aviation tourism had a significant positive (+) effect on the cognitive ability, affective ability, and behavioral ability, which are components of self-directed learning ability. Third, it was found that the consistency of interest and persistence of effort of college students majoring in aviation tourism had a significant positive (+) effect on cognitive, emotional, and behavioral abilities, which are components of self-directed learning ability. Fourth, the mediating effect of grit in the effect of growth mindset on self-directed learning ability of college students majoring in aviation tourism is the consistency of interest in grit in cognitive ability, affective ability, and behavioral ability of growth mindset and self-directed learning ability. It has been shown to be partially mediated. Also, in the cognitive abilities of growth mindset and self-directed learning ability, the persistence of grit efforts was found to partially mediate. Perseverance in grit efforts partially mediates the affective and behavioral abilities of the personality- growth mindset and self-directed learning ability. It was found that persistence of grit effort completely mediated in the affective and behavioral abilities of intelligence-growth mindset and self-directed learning ability. The results of this study show that the growth mindset has a positive effect on the self-directed learning ability of college students majoring in aviation tourism through the medium of grit. Therefore, in order to improve the self-directed learning ability of college students majoring in aviation tourism, it is required to operate a curriculum and use teaching methods based on an understanding of growth mindset and grit.

정영미,김용광 한국정보관리학회 2008 정보관리학회지 Vol.25 No.4

This study investigates an event detection method with the aim of generating an event-focused news summary from a set of news articles on a certain event using a multi-document summarization technique. The event detection method first classifies news articles into the event related topic categories by employing a SVM classifier and then creates event clusters containing news articles on an event by a modified single pass clustering algorithm. The clustering algorithm applies a time penalty function as well as cluster partitioning to enhance the clustering performance. It was found that the event detection method proposed in this study showed a satisfactory performance in terms of both the F-measure and the detection cost. 이 연구에서는 사건중심 뉴스기사 요약문을 자동생성하기 위해 뉴스기사들을 SVM 분류기를 이용하여 사건 주제범주로 먼저 분류한 후, 각 주제범주 내에서 싱글패스 클러스터링 알고리즘을 통해 특정한 사건 관련 기사들을 탐지하는 기법을 제안하였다. 사건탐지 성능을 높이기 위해 고유명사에 가중치를 부여하고, 뉴스의 발생시간을 고려한 시간벌점함수를 제안하였다. 또한 일정 규모 이상의 클러스터를 분할하여 적절한 크기의 사건 클러스터를 생성하도록 수정된 싱글패스 알고리즘을 사용하였다. 이 연구에서 제안한 사건탐지 기법의 성능은 단순 싱글패스 클러스터링 기법에 비해 정확률, 재현율, F-척도에서 각각 37.1%, 0.1%, 35.4%의 성능 향상률을 보였고, 오보율과 탐지비용에서는 각각 74.7%, 11.3%의 향상률을 나타냈다.

Bupleurum falcatum has been used for treatment of inflammation, jaundice, influenza and hepatitis as a traditional orient folk medicine. This experiment was carried out to evaluate the effect of B falcatum extract on cellular immune responses in vivo and in vitro. Antigen binding cell(ABC) assay, antibody production, Arthus and delayed-type hypersensitivity(DTH) reaction against sheep erythrocytes(SRBC) were very depressed in B falcatum extract treated group in vivo. The growth of Staphylococcus aureus in brain heart infusion(BHI) broth containing B falcatum extract was remarkably inhibited. Otherwise, that of Salmonella typhyimurium was not significantly increased in vitro. When B falcatum extract pretreated mice were intraperitoneally(IP) injected S typhimurium and S aureus, respectively, the number of bacteria in peritoneal exudates were time dependent declination compared with those of control, and the weight of spleen and the number of macrophage migration into peritoneal cavity have no difference from those of untreated control. B falcatum extract gradually increased phagocytic activities of peritoneal macrophage against Candida albicans time and dose dependently, and was not significant production of migration inhibiotory factor(MIF). But migration abilities of normal leucocytes in B falcatum extract pretreated group were decreased dose dependently. When B falcatum extract was IP administered, these data indicate that B falcatum extract increases level of serum coticosterone. Therefore, B falcatum extract was indirectly mediated in immune system by serum coticosterone having relation to immunosuppression. These results lead to the conclusion that B falcatum extract acts as a trigger or regulator of cellular immune responses in immune system.

정영미(鄭榮美) 한국일본어학회 2014 日本語學硏究 Vol.0 No.41

This study is to find out the relationship between the topic selection and politeness in Korean and Japanese conversation. The subjects were female undergraduates who took part in the invitation conversation. The results of the study are summarized as follows. (1) Both Korean and Japanese speakers tend to prioritize their active communication through being considerate of their partners rather than aim to take part in the conversation. (2) When they select their topics, both Korean and Japanese speakers tend to talk about the subjects which they share each other. Therefore, these findings indicate that the mechanism of positive politeness strategies can be affected when female speakers, who are in close relationship, select their topics in the conversation. (3) When they introduce their topics, both Korean and Japanese speakers tend to develop new topics by mentioning parts of previous contents on speech acts. These tendencies were more obvious in Japanese than Korean. Both Korean and Japanese speakers tend to introduce topics by mentioning the contents of proposition by themselves rather than introduce new topics by requesting some information about their partners. As the results of this study show, the findings provide that the participants had a cooperative attitude in this conversation, thus this conversation had an effect on satisfying their partners’ positive face.

誘い発話文の述部の表現に関する一考察 - ポライトネス理論の観点から -

정영미 일본어문학회 2011 일본어문학 Vol.55 No.-

本稿では準自然会話における誘い発話文の述部の表現を取り上げ、ポライトネス理論の観点から考察した。韓国語では計26の誘い発話文の中で、「~자」と「~ㄹ까」の使用が圧倒的に多かった(計約88%)。その他に「~아야지」、「~잖아」、「~ㄴ거야」が用いられている。この中で「~자」、「~잖아」、「~는거야」は相手のポジティブ․フェイスへの配慮行動として働き、「~ㄹ까」と「~아(어)야지」は相手のネガティブ․フェイスへの配慮行動として働くことが明らかになった。日本語では計17の誘い発話文が抽出でき、「~シヨウ」、「~シナイ(カ)」、「~シタクナイ(カ)」、「~シタイ」、「~スル(カ)」、「時間の表現+アル(カ)/ナイ(カ)」、「~シニオイデ」の8種類の表現が抽出できた。その中で、「~シヨウ」が半数近くの使用割合を占め、残りの表現はほぼ均等な使用割合を占めていた。「~シヨウ」と「~シニオイデ」は相手のポジティブ․フェイスに向けられた配慮行動であり、「~シナイ(カ)」、「~スル(カ)」、「~シタクナイ(カ)」、「時間の表現+アル(カ)/ナイ(カ)」は相手のネガティブ․フェイスに向けられた配慮行動であることが分かった。そして、「~シタイ」は配慮の度合いが最も大きいほのめかしに該当することが分かった。
