Triple-negative breast cancer (TNBC) has a higher risk of death within 5 years of being diagnosed than the other forms of breast cancer. It is the second leading cause of death due to cancer among women. Currently, however, no diagnostic blood-based biomarker exists to identify the early stages of TNBC. To address this point, we utilized a human protein microarray system to identify serum autoantibodies that showed different expression patterns between TNBC and normal serum samples, and identified five autoantibodies showing TNBC-specific expression. Among them, we selected the thioredoxin-like 2 (TXNL2) autoantibody and evaluated its diagnostic relevance by dot blot analysis with the recombinant TXNL2 protein. We demonstrated that the TXNL2 autoantibody showed 2- to 6-fold higher expression in TNBC samples than in normal samples suggesting that serum TXNL2 autoantibodies are potential biomarkers for TNBC.
Korean university EFL students’ motivation, demotivation, and attitudes toward learning English
정지민,변지현 한국언어연구학회 2020 언어학연구 Vol.25 No.1
This study investigated Korean university EFL students’ motivation, attitudes and demotivation in relation to their perceived English proficiency, using 11 variables. A total of 279 EFL students, enrolled in 1st-year English, participated in this study. Overall, the students showed high levels of internal motivations, which are assumed to be stronger motives than instrumental motives, and relatively low levels of demotivation, implying that the participants already have potential to be successful foreign language learners. Affect-related variables showed significant and positiv e correlations with the students’ perceived English proficiency levels and cognition-related variables did not show or had very small impact on the students’ perceived English proficiency. Regression data showed that Ideal L2 self explained about 30% of the perceived English proficiency. Thus, students in this study who had higher levels of internal motivation and more positive attitudes to English speakers and English language learning tended to consider their level of English proficiency to be higher and vice versa.

이 연구의 목적은 현대무용 관람에 대한 일반인 관람객들의 유형과 특성을 파악하기 위해 공연선택요인의 주관 적 특성을 분석함으로써 공연소비패턴에 대한 상세한 관점을 이해하는데 목적을 두고 주관성 연구로 대표적인 Q 방법론 (Q-method)을 사용하여 분석하였다. 이상의 과정을 통해 도출된 유형별 분석결과는 다음과 같다. 첫째, 현 대무용 공연선택요인은 최종적으로 다섯 가지 유형으로 분류되었으며, ‘제 1유형’은 다양성경험을 통한 영감추구 아티스트형(N=16)', '제 2유형‘은 ’지인출연이나 권유를 통한 공연경험형(N=11)', '제 3유형‘은 ’무용가의 능력추구 형(N=6)', '제 4유형‘은 ’지적호기심을 가진 공연입문자형(N=2)', '제 5유형‘은 홍보를 통한 공연경험형(N=5)’ 으로 유의미하게 분류되었다. 이상과 같이 도출된 결과는 실제 공연장을 방문하는 일반인 공연관람객의 공연관람경로 파악과 개인적 특성에 따른 공연선택요인을 제시함으로써 점진적이고 지속적인 마케팅 방법을 마련할 수 있을 것이다. The purpose of this study is to understand performance consumption patterns by analyzing the subjective characteristics of performance selection factors in order to understand the type and characteristics of the audience about the modern dance. Therefore, we looked at detailed aspect of the consumption patterns that are missing in the previous researches, and analyzed by using representative Q-method as the subjectivity study in order to supplement those factors. The results of the analysis by these processing are as follows. First, the selection factors of contemporary dance performances were finally classified into five types. The first type is 'inspiration pursuing artist type through experience of diversity'(N=16)', The second type is performances experiencing type based on acquaintance (N=11)’, The third type is Dancer's ability-pursuing type (N=6)’, The fourth type is performance beginner type with intellectual curiosity(N=2), The fifth type is performances experiencing type through the promotion (N=5). As a result, it is possible to establish a gradual and sustainable marketing method by presenting the selection factors of performances according to individual characteristics, and grasping the paths of performances of public performance watchers . This will provide basic data for activating the dance performance market by deriving the popularity and appropriate consensus without fading the essence of modern dance as a fine art.
