Korean male college students are found to prefer using the trend of ‘core discourse’ after judging damage situations by ‘negotiation discourse’ and less by ‘successive core discourse,’ which continuously uses ‘apologies’. In contrast, Japanese male and female college students show the trend of continuing the interaction to solve the problem by ‘negotiation discourse’ after using ‘apologies’ first by ‘core discourse’ or ‘successive core discourse’. Moreover, it was observed that Korean female college students show almost the same rate of using ‘core discourse’ after judging the situation by ‘negotiation discourse’ and continue to use ‘negotiation discourse’ after using ‘core discourse’; they also use slightly more ‘successive core discourse’ than Korean male college students.

PI3K/Akt/mTOR Mediated Anti-proliferation by the Extract of Fungus Chaetomium sp. in SK-Hep1 Human Hepatocellular Carcinoma Cells

정현일,김군도,손병화 대한암예방학회 2012 Journal of cancer prevention Vol.17 No.1

The marine environment has immeasurable diversity of the chemical and the biological compounds and is an extraordinary resource for the discovery of new anti-cancer drugs. In this study, we investigated the anti-cancer effect of the extract of marine algae-derived symbiotic fungus Chaetomium sp. on SK-Hep1human hepatocellular carcinoma cells. The extract exhibited inhibition of cell proliferation by inducing apoptosis, cell cycle arrest at G1/S phase and autophagic cell death. The results showed that apoptosis resulted from the activation of pro-apoptotic proteins (tBid, Bad, PUMA) and caspases (-3 and -8). We identified that the extract arrested cell cycle at sub-G1 phase and increased expression of p21CIP1/WAF1while reduced expression of cdc25A and E2F-1. The extract also inhibited the activation of PI3K regulatory subunit (PI3K p110α) and downstream targets such as Akt, mTOR and p70S6K. The cells treated with the extract finally showed autophagy by the up-regulation of Atg5, 7, 12 and LC3B. The results suggested that the extract of fungus Chaetomium sp. has a potential anti-cancer effect on SK-Hep1cells.

Computer Graphics in Art and Design Education - Exploring History, Characteristics, and Applications -

정현일 한국교원대학교 교육연구원 2010 敎員敎育 Vol.26 No.4

Over the fifty-year history of computer graphics, there have been continuous changes and advances that have significantly affected our daily lives and education. The field of art and design education has been especially influenced by computer technologies, long considered one of the most powerful resources for teaching and learning in visual arts. However, many art educators and administrators in higher education are struggling with how to incorporate new computer graphics programs into art and design education, and how to develop an interdisciplinary curriculum associated with computer graphics in order to teach students effectively. Therefore, this article first examines the history of computer technologies and secondly discusses the five important characteristics of computer graphics to help us understand how these interdisciplinary teaching programs originated and why computer graphics is regarded an art medium comparable to other traditional media. Finally, this article explores two separate interdisciplinary curricula to give an idea how we incorporate computer graphics coursework into art and design programs in higher education.

대학생의 부전공, 복수전공 만족도 결정요인에 관한 연구

정현일,류영진 한국콘텐츠학회 2019 한국콘텐츠학회논문지 Vol.19 No.4

본 연구의 목적은 대학생의 부전공, 복수전공 만족도 결정요인을 탐색하는 것이다. 이를 위해 대학의 조교들과 F.G.I를 수행하여 설문지를 제작했다. 설문조사는 부전공, 복수전공을 이수하는 총 239명의 대학생들을 대상으로 진행했다. 자료분석은 통계 프로그램 (SPSS)를 사용했으며 요인분석, 신뢰도검정, 다중회귀분석을 실시하였다. 먼저 부전공, 복수전공 관련 설문문항에 요인분석을 실시하여 필요-성취, 수업차별, 수강신청차별이라는 3가지 주요 요인을 도출했다. 다음으로 주요 요인들의 영향을 확인하는 다중회귀분석 실시하였다. 분석 결과 주요 요인들이 유의미하게 나타났다. 영향의 정도는 필요성취, 수업차별, 수강신청차별 순으로 높게 나타났다. 결론에서는 부전공, 복수전공의 긍정적 기능과 가능성을 제안하였다. The purpose of this study was to explore the determinants of minor and double major satisfaction of university students. To achieve this, F.G.I. was performed with the university teaching assistants to create a questionnaire. The survey was performed to the subject of 239 university students completing minor and double major. A statistical program (SPSS) was used for data analysis and factor analysis, reliability analysis, and multiple regression analysis were conducted. First, it drew three principal factors including need-achievement, class discrimination, and course registration discrimination by conducting factor analysis regarding survey questions on minor and double major. Next, the multiple regression analysis identifying the effects of the three principal factors was conducted. The results indicated three principal factors to be statistically significant. The degree of influence over satisfaction marked the highest in the order of need-achievement, class discrimination, and course registration discrimination. In the conclusion, the positive function and possibilities of minor and double major are proposed.

물질적인 피해상황에서의 사죄행동의 한일대조 - 상호작용의 특징을 중심으로 -

정현아(鄭賢兒) 한국일본어학회 2019 日本語學硏究 Vol.0 No.62

The purpose of this study is to qualitatively analyze, on the basis of actual conversational data, the kinds of language strategies Korean and Japanese male and female university students use in order to interact with each other when restoring their relationships. When Korean and male and female students had positive and smooth conversations, apologizers uttered expressions of apology (미안하다), acceptance of responsibility, and damage reimbursement in order to actively solve the problem. The opponent of the apologizer also utilized utterances of acceptance and accepted the apologizer’s apologetic behavior when there was the possibility of problem-solving. However, when Korean male students faced negative and unsmooth conversations, the opponent of the apologizer continuously and directly blamed the apologizer, and the apologizer tended to show avoidance of responsibility and utterances of complaint expressions to reject the apologizer’s apologetic behavior. Korean female students utilized words showing friendliness such as ‘friend’ to alleviate damage somewhat when blame between friends or other situations of losing face occurred. When Japanese and male and female students had positive and smooth conversations, the apologizer continuously used expressions of apology (ごめん、すまない、申し訳ない) and uttered acceptance of responsibility and damage reimbursement to solve a problem. The opponent of the apologizer also tended to use concession and utterances of acceptance, rather than utterances of the clear demand for damage reimbursement. In negative and unsmooth conversations, Japanese male student apologizers tended to politely express ending words when the willingness for damage reimbursement was uttered even between friends. When opponents of apologizers are Japanese female students, they tended to use indirect blame more frequently compare to other groups, to avoid linguistic behaviors that could cause the other to lose face.

This study analyzed the knowledge production mechanism and research trends of domestic area studies through text mining. The research method utilizes network analysis and topic modeling analysis, and the subject of the study is an academic journal as a knowledge production mechanism. First, using KCI’s database, an academic journal corresponding to area studies of broadness was selected as a object of analysis.. The research status of these journals, the subject of production of area studies knowledge, and the composition of each academic field were confirmed. Next, using the selected academic journal as a sample, data were collected with the title and major keywords of the paper published in the journal, and text mining was conducted. First of all, as a result of network analysis, keywords related to East Asian and social science concepts were major. Finally, the main topics and characteristics of area studies were identified through topic modeling analysis. Through topic coherence analysis, It was confirmed that six topics are the optimal number of topics. In order to understand the characteristics of the topics well, we analyzed it by setting lambda(λ) to 0 or 1. The discussion pointed out that domestic area studies are being conducted mainly in East Asia, especially the Trans-Pacific, and that humanities-based area studies have a large proportion under the influence of the sub-disciplinary field. Considering this trend, this study proposed “global area studies” as “area studies 3.0,” including “variations in globality,” comparative area studies, and research on mega-regions as the direction of future area studies.
