김희란(金喜蘭) 서울대학교 교육연구소 2021 아시아교육연구 Vol.22 No.2

본 연구의 목적은 대학생을 대상으로 R을 이용하여 모형 기반 잠재프로파일 분석방법(model-based latent profile analysis)을 적용하여 대학생들의 학습참여(student engagement)를 유형화함으로써 대학생 학습활동을 이해하는 것이다. 전국 4년제 일반대학에 재학 중인 학생을 대상으로 K-NSSE(Korea-National Survey of Student Engagement) 측정도구를 이용하여 온라인 설문조사를 통해 수집된 1,178명의 표본을 분석하였다. 분석결과, 3개의 학습참여 유형이 추출되었으며, 잠재집단들은 표본 수에서는 차이가 나지만 유사한 축을 가지는 타원형 분포를 띄는 모형(VEE, Ellipsoidal, Variable volume, Equal shape, and Equal orientation)이 가장 적합한 것으로 나타났다. 학습참여 유형은 특징에 따라 ‘적극형’, ‘보통형’, ‘소극형’으로 명명되었다. ‘교수와 상호작용’ 변인이 유형 분류에 중요한 역할을 하고 있음이 밝혀졌다. 뿐만 아니라, ‘적극형’ , ‘보통형’, ‘소극형’ 순으로 대학생활을 통한 역량 함양 정도, 교육만족도, 대학몰입도를 높게 보고하였다. 본 연구 결과는 대학생들이 학습참여에 적극적일수록 학습성과가 높다는 선행연구결과를 지지하였으며 인지적 학습성과뿐만 아니라 정의적 학습성과 또한 학습참여의 적극성 정도와 관련되어 있음을 입증하였다. 대학생의 학습지원과 관련하여 본 연구결과의 시사점이 논의되었다. The purpose of this study is to understand learning activities of undergraduate students by applying the model-based latent profile analysis and classifying the typology of student engagement in learning. 1,178 data were collected from 4-year undergraduate students who had responded to the K-NSSE assessment via online survey. Results showed that three types of learning engagement were developed. The fittest model of latent groups was the ellipsoidal model with variable volume, equal shape and orientation among groups. The learning engagement was classified into active, ordinary, and passive types. The participants of active type showed higher scores on GPA, perceived competencies, educational satisfaction, and immersed level in college activities than other types. The results supported previous study outcomes that the more undergraduate students are active in their learning engagement, the higher their achievements are, and that the level of active engagement is associated with emotional learning outcomes as well as cognitive outcomes. Implications of study results were discussed regarding supports for learning of undergraduate students.

In this study, In the era of corona pandemic the types of customers who visit Chinese restaurants are classified according to the personal opinions of customers. In order to understand the subjective characteristics of consumer needs and consumption behavior, 119 adults were set up and analyzed according to the Q methodology analysis. The first type is “management know-how”. The second type is “the atmosphere-seeking type of a Chinese restaurant”, and it appears that the hygiene and atmosphere of a Chinese restaurant are judged by the value of the Chinese restaurant. The third type is “the type that seeks the essence of Chinese food”, and they want traditional food, seek diversity in Chinese food menus, and want to provide basic services.

To elucidate the antimutagenic action mechanism of flavonoids against benzo(a)pyrene induced micronucleated polychromatic erythrocytes (MNPCEs), alterations of benzo(a) pyrene metabolism were studied. Galangin, a potent antimutagen and (-)-epicatechin, a weak one, were selected and orally administered to ICR mice to compare the liver metabolic enzyme activities, arylhydrocarbon hydroxylase (AHH) and glutathione-s-transferase (GSH-T). These enzyme activities were not significantly changed between the flavonoid-treated groups and the control group. However, direct addition of galangin to the incubation mixture clearly inhibited arylhydrocarbon hydroxylase activity. These results were well correlated with the findings of the reduced metabolic conversion of [³H]-benzo(a)pyrene in vitro.

주지하듯이 신라사회는 골품제사회이며, 골품제도의 정치적 기능 가운데서 가장 중요한 것은 일정한 官職에 나갈 수 있는 자격을 규정한 官等에 대한 규제이다. 다시 말해 官等制度는 일면에 있어서 신분계층을 구분하는 제도적 장치였으나, 다른 면에 있어서는 官職的기능을 대행하는1) 것이기도 하다. 이는 관등과 관직의 성격이 상호 밀접한 연관관계 아래에서 작용하였던 점을 말해주는 것이기도 하다.
