다문화가정청소년의 이중문화수용태도에 따른 잠재집단 분류 : 영향요인 탐색 및 집단에 따른 우울과 학교적응의 차이

정옥,이수경 한국청소년시설환경학회 2024 청소년시설환경 Vol.22 No.3

This study was conducted to classify latent groups according to the bicultural acceptance attitude of adolescents from multicultural families, to search for influencing factors, and to find out differences in depression and school adjustment according to groups. Using the 9th data from the Multicultural Youth Panel Survey by the National Youth Policy Institute in 2019, latent profile analysis was conducted using the M-plus 8.8 program. Subsequently, Multinomial logistic regression analysis and cross-analysis were used to exam differences in influencing factors, depression, and school adjustment. As a result of the study, the bicultural acceptance attitude latent group was classified into three groups. They were named as the intermediate bicultural acceptance group, high Korean cultural acceptance group, and high bicultural acceptance group. Factors such as self-esteem, maternal parenting attitude, nationality, and child's gender were identified as influencing factors in the latent profile classification. In addition, as a result of analyzing the differences in depression and school adjustment according to the bicultural acceptance attitude latent group, statistically significant differences were found in both depression and school adaptation. Adolescents in the intermediate bicultural acceptance group exhibited higher levels of depression, while school adjustment scores followed the order of high bicultural acceptance, high Korean cultural acceptance, and intermediate bicultural acceptance groups respectively. This study is expected to provide academic help to research on bicultural acceptance of adolescents from multicultural families and contribute to the preparation of educational and counseling measures.

In order to determine the effect of tomato(Lycopersicon escylentnm mill ssp.) on the yogurt quality, skim milk powders were added with tomato juice of 0%, 1%, 3%, 5% and fermented by mixed culture(Streptococcus salivarius subsp. thermophilus and Lactobacillus delbrueckii subsp. bulgaricus. The results were summarized as follows: 1. Addition of tomato juice in skim milk decreased pH(4.3) and increased acidity(0.93%) more than control did(pH 4.6, titratable acidity 0.85%). By the addition of tomato juice, acid production was increased and pH was decreased in proportion to concentrations of tomato juices added to skim milk. 2. The number of lactic acid bacteria in yogurts added with tomato juice (4.59×10^12cfu/ml) more increased than those in control yogurt(8.96×10^11cfu/ml). By the addition of tomato juice, the number of lactic acid bacteria counts increased in proportion to concentration of tomato juices added to skim milk. 3. As fermentation time goes by, the Brix degree sugar content in skim milk were decreased more rapidly than control. 4. The pH, titratable acidity, Brix degree and lactic acid bacteria were not significantly changed for all yogurts for the storing at 5℃ for 14 days. 5. In yogurt fermentation, addition of tomato juice with glucose (1% tomato juice + 4% glucose, 3% tomato juice + 2% glucose, 5% tomato juice + 0% glucose) decreased pH and increased acidity than control(5%glucose) did. In addition of tomato juice, acidity was increased and pH was decreased in proportion to concentration of tomato juices added to skim milk. 6. In yogurt fermentation, the number of lactic acid bacteria of yogurt added with tomato juice(1% tomato juice+4% glucose, 3% tomato juice+2% glucose, 5% tomato juice+0% glucose) increased than control(5% glucose). In addition of tomato juice, the number of lactic acid bacteria increased in proportion to concentration of tomato juices added to skim milk. 7. As fermentation time goes by, the Brix degree were decreased more rapidly than control(5% glucose). By the change of pH, titratable acidity, Brix degree and lactic acid bacteria, in yogurt fermentation, we definited that the promotive effect of tomato(Lycopersicon escylentnm mill ssp.) on the yogurt.

사회정체성 불확실성과 자기-해석이 내집단 동일시 및 집단 이탈의도에 미치는 영향: 조절된 매개모형 검증

정옥아,최훈석 한국사회및성격심리학회 2024 한국심리학회지 사회 및 성격 Vol.38 No.2

본 연구는 사회정체성 불확실성(정체성-불확실성, 소속감-불확실성)과 자기-해석의 상호작용이 내집단 동일시를 매개로 내집단 이탈의도를 예측하는 모형을 검증하였다. 내집단을 ‘한국인’으로 제시하여 한국 대학생(N = 121)을 대상으로 조사한 결과, 내집단의 전형적 특징이 모호함에 따라 발생하는 정체성-불확실성은 상호의존적 자기-해석보다 독립적 자기-해석이 우세한 경우 내집단 동일시를 부적으로 예측했고, 내집단 동일시가 약할수록 내집단 이탈의도가 강하게 나타나서 조절된 매개효과가 관찰되었다. 반면에 자신이 내집단의 전형적 구성원인지가 불확실할 때 경험되는 소속감-불확실성에서는 유의미한 결과가 관찰되지 않았다. 사회정체성 불확실성과 관련하여 본 연구가 지니는 함의와 장래 연구 과제를 논의하였다. The present study examined a moderated mediation model that stipulates an interaction of the two subcomponents of social identity uncertainty (identity-uncertainty and membership-uncertainty) and individuals’ self-construal in predicting ingroup identification (i.e., national identification), which in turn predicts intention to leave the ingroup (i.e., South Korea). We surveyed a total of 121 South Korean undergraduates and found that identity-uncertainty predicts the exit intention via ingroup identification only among individuals with an independent self-construal. By contrast, no significant relationships were found when the model included membership-uncertainty as a predictor. Implications of these findings and directions for future research on social identity uncertainty are discussed.

블록 코딩을 활용한 동역학 수업에서 나타나는 물체의 운동 개념 변화 과정

정옥(Ok Jeong),오원근(Wonkun Oh) 한국물리학회 2022 새물리 Vol.72 No.11

본 연구는 블록 코딩을 활용한 수업을 통해 동역학의 기초라고 할 수 있는 위치와 변위, 속도, 가속도의 개념이 학생에게 어떤 형태로 형성되어 있고 어떻게 변화되어 가는지, 이 과정에서 어떠한 메타인지적 과정이 이루어지고 있는지 알아보는 데 목적이 있다. 이를 위해 5명의 학생들과 1:1로 수업을 진행하면서 학생들에게 형성되어 있는 개념을 확인할 수 있도록 코딩을 유도하는 질적 연구를 진행하였다. 그 결과 학생들에게 형성되어 있는 동역학 관련 오개념이나 개념적 어려움을 확인하였으며, 학생 스스로 경험하는 인지적 갈등과 갈등 해소 과정에서 나타나는 메타인지적 과정을 확인할 수 있었다. This study examines how students concepts of position, displacement, speed, and acceleration, which can be said to be the basis of dynamics, are formed and changed through the teaching of dynamics by using block coding and how metacognitive processes are enhanced in this process. A qualitative study was conducted on five students who engaged in a teaching class that introduced the block coding method to enable the students to check their own concepts. As a result, it was possible to discover misconceptions or conceptual difficulties related to dynamics that were formed in students, and to observe the cognitive conflicts experienced by the students themselves and the metacognitive process that appeared in the conflict resolution process.

Cervical cancer is one of the leading causes of female death from cancer worldwide with about 500,000 deaths per year. A strong association between certain human papilloma viruses (HPV types 16 and 18) and cervical cancer has been well known. An extract of natural products, named as Somatid, has been used to investigate whether this agent has the ability of inhibiting the oncogenes E6 and E7 of HPV type 16. This Somatid inhibited the proliferation of human cervical cancer cell lines (C-33A, SiHa, CaSki) and HaCaT keratinocytes in a dose response manner. In vitro binding assay and ELISA showed that Somatid inhibited the in vitro biding of E6 and E6AP which are essential for the binding and degradation of the tumor suppressor p53. In addition, Somatid inhibited the in vitro binding of E7 and Rb which is essential tumor suppressor for the control of cell cycle. The levels of mRNA for E6 and E7 were also decreased by Somatid. Our data suggested that Somatid inhibited the oncogenecity of E6 and E7 of HPV 16 type, thus can be used as a putative anti-HPV agent for the treatment of cervical carcinomas caused by HPV.

Prosody Generation Based on C-ToBI Representation for Text-to-SpeechSeungwon Kim, Yu Zheng, Gary Geunbae Lee, Byeongchang KimProsody modeling is critical in developing text-to-speech (TTS) systems where speech synthesis is used to automatically generate natural speech. In this paper, we present a prosody generation architecture based on Chinese Tone and Break Index (C-ToBI) representation. ToBI is a multi-tier representation system based on linguistic knowledge to transcribe events in an utterance. The TTS system which adopts ToBI as an intermediate representation is known to exhibit higher flexibility, modularity and domain/task portability compared with the direct prosody generation TTS systems. However, the cost of corpus preparation is very expensive for practical-level performance because the ToBI labeled corpus has been manually constructed by many prosody experts and normally requires a large amount of data for accurate statistical prosody modeling. This paper proposes a new method which transcribes the C-ToBI labels automatically in Chinese speech. We model Chinese prosody generation as a classification problem and apply conditional Maximum Entropy (ME) classification to this problem. We empirically verify the usefulness of various natural language and phonology features to make well-integrated features for ME framework.
