This study evaluated the effect of the music type (analog and digital) on the grip strength. Five male and five female healthy college students participated in the experiment. The independent variables were music type (analog, digital, no music) and listening time (5 min., 10 min., and 15 min.). The classic LP disc was used as the analog music and the LP was converted to mp3 to make the digital music source. Grip forces were measured every 5 minutes until 15 minutes using Jamar strain guqge. Mean forces and peak forces were used as dependent variables. The analysis of variance showed that there was no difference between analog and digital music (p>0.05). Only, the gender effect was statistically significant (p<0.05). These results should be verified using different types of music (not only classical music) or preferred music, during different listening time duration (>15 minutes).

This study investigated differences in university students’ creative self-efficacy by gender and major to evaluate the educational efforts applied to increase their positivity. The general mandatory course Action, Communication, Teamwork (A.C.T.) from C University of Seoul is a student-centered class that applies art-based learning materials. During A.C.T. classes, students participate in artistic and creative activities in teams. Through the process, it was revealed that students enrolled in such classes improved their creative self-efficacy. The study investigated 812 students from 22 classes to survey changes by individual characteristics. Three trends were identified. First, there was a difference in creative self-efficacy by gender: male students had higher scores than female students in both pretests and posttests. Second, the College of Arts had the highest levels of creative self-efficacy. Third, the greatest differences in creative self-efficacy levels were found in Business and Economics majors, followed by Social Sciences, Arts, and Engineering majors. Interestingly, majors with the greatest differences in creative self-efficacy scores were not limited to those with higher pretest scores. The results of the study are provided with the aim of contributing to further development in creativity education.

최민지 ( Choi Min Ji ) 한국예술교육학회 2020 예술교육연구 Vol.18 No.2

The purpose of this study is to determine whether the grading method of creativity education provided as a university course causes change to creative self-efficacy. The subjects were 787 university students divided into 19 classes during four semesters who took the common liberal arts course Action Communication Teamwork (A.C.T.) from the first semester of 2018 to the second semester of 2019 at Seoul’s C University. Previous studies proved that participating in artistic activities in A.C.T. increases creative self-efficacy. To explore the characteristics and formation system of creative self-efficacy in more detail, two groups with different grading methods were examined: Group A was graded by Type A, a theory-based assessment method, and Group B was graded by Type B, a practice- based assessment method. Data from the pretest-posttest surveys were collected using the creative self-efficacy scale. SPSS/WIN Statistics 22.0 was used for data analysis, and an independent samples t-test was conducted to determine homogeneity between the groups. ANCOVA was conducted to determine the difference between the groups, and Cohen's was used to verify the size of the difference. The results showed that the difference in the grading method affected creative self-efficacy. The difference between the two groups existed throughout the pretest and posttest; Group B showed a smaller level of difference than Group A.

원주지역 공동체문화 실천과 민속학적 사유의 구상

최민지(Choi, Min-ji) 안동대학교 민속학연구소 2021 공동체문화와 민속 연구 Vol.2 No.-

사회적경제는 신자유주의적 자본주의로부터 야기되는 위기에 대한 대응 혹은 대안으로 인식되고 있고, 그러한 인식 속에서 현재의 실천지형이 그려지면서‘사회적인 것’혹은 ‘공동체적인 것’이 결국은 기존의 정치와 경제의 체제에 포획되고 있다는 진단이 가해지고 있다. 본 연구는 이처럼 ‘사회적경제’에 가해지고 있는 비판적 물음들과 현실적 모순들로부터 벗어난, 다른 논의의 가능성들을 발견하기 위한 기획이다. 사회적경제라는 개념과 현상이 지시하고 있는 현재적 의미를 민속학적으로 재구성하여 다른 해석의 가능성을 발견하는 작업을 제안하고자 한다. ‘사회적경제’가 제도와 담론에 국한된 대상이 아닌, 매우 다층적인 실천과 역사적 층위에서 생성하고 있다는 점에 대한 강조로부터 새로운 인식의 지점이 마련될 수 있을 것이다. 그 사례로, 민간 주도 협동운동의 역사성과 현재성을 두루 갖추고 있고, 사회적경제 실천을 통한 지속가능한 삶의 모색이 적극적으로 이루어지고 있는 강원도 원주를 주목한다. 현재 수행되고 있는 원주지역의 사회적경제의 실천에서는, 명시적인 개념으로 확립될 수 없는 공동체문화적 관계와 민속의 변환을 발견할 수 있다. 그러한 관계들의 존재성을 민속학적 차원에서 접속 해봄으로써, 사회적경제라는 개념의 명시적이고 지식적인 차원의 비대칭적 보완, 즉 변환 혹은 생성의 민속적 보충을 지적해보고자 한다. 이는 사회적경제의 생성적 의미를 민속적으로 규명해보는 하나의 시도로서, 지배문화가 제대로 인식하기 어려운 틈새에 배치되는 사회적경제 실천의 의미와, 실천 자체로 명명될 수 없는 잠재태(혹은 여전히 생성적이라는 의미에서 잠정적)에 대한 사유라고 할 수 있다. The Social economy is perceived as a response or alternative to the crisis caused by neoliberal capitalism, and the present practice landscape is portrayed in such awareness, and it is diagnosed that “social” or “communal” is eventually captured by existing political and economic systems. This study is designed to discover other possibilities of discussion, away from the critical questions and realistic contradictions posed to the ‘social economy’. We would like to propose a work to discover the possibility of different interpretations by folklore reconstructing the concept of a social economy and the present meaning that the phenomenon dictates. A new point of perception could be established from the emphasis that the ‘social economy’ is not limited to systems and discourse, but is generating from very multilayered practices and historical strata. As an example, Wonju, Gangwon Province, which has both the historical and present nature of a private-led cooperative movement and actively seeks sustainable life through social and economic practice, pays attention to it. In the practice of the various social economies currently being carried out, a transformation of community cultural relations and folklore that cannot be established by explicit concepts can be found. By accessing the existence of these relationships at a folk level, we would like to point out the asymmetric complement of the explicit and intellectual dimension of the concept of social economy. This is an attempt to folklore understand the latent state (or provisional) of the social economy, which is in the midst of difficulty in recognizing the culture of domination, and which is not in practice itself.

The purpose of this study was to compare the characteristics and irritation potentials of three commercially available 3D skin models (EpiDerm^TM SIT, LabCyte EPI-24 and KeraSkin^TM-VM) that use human keratinocytes as an alternative means of testing skin irritation. The test substances were applied on the surface of insert cells after pre-incubation (24 h). The test substances were completely washed, and then models were incubated for 48 h. Cell viability was measured using the MTT assay to measure levels of skin irritation. Quality control indices, such as barrier function (TEER), absorbance of negative control, cell viability of positive control, absorbance of extraction buffer used in MTT assay, acceptability range (upper and lower limit), and results range and consistency between inserts, were in agreement with the acceptance criteria. With the exception of 4-methylthio-benzaldehyde (negative substance in globally harmonized system (GHS)), which led to false positives in all 3 models of the preliminary study, other test substances showed consistent results with the GHS for classification standards in OECD Guideline 439. Taken together, results for sensitivity, specificity, and accuracy of the three models were 100, 67, and 83%, respectively; these values are on par with OECD Guidelines.

COVID-19로 인한 비대면 창의성 계발 수업의 창의적 자기효능감 변화와 대면 수업과의 차이 탐색

최민지 ( Choi Min Ji ) 한국예술교육학회 2021 예술교육연구 Vol.19 No.3

This study seeks to explore how non-face-to-face creativity education at universities influences learners' creative self-efficacy. As society, as a whole, changed in response to COVID-19, the education community began to shift to non-face-to-face methods, but various concerns and problems were faced. Unfortunately, the unprecedented crisis is continuing, and the possibility of another crisis cannot be ruled out. Accordingly, the aim of this study is to identify examples, processes, and effects of non-face-to-face creativity education that can respond to crises and is sustainable, as well as to propose potential solutions. To attain this objective, a total of 473 students at C University in Seoul, including 194 students who participated in face-to-face classes and 279 students who participated in non-face-to-face classes, were studied to measure their creative self-efficacy before and after the classes. A response sample t-test was conducted for the analysis of in-group effectiveness, while an independent sample t-test was used to determine whether there were significant differences between groups. The subfactors of creative self-efficacy, namely self-efficacy in creative thinking and self-efficacy in creative performance, were also examined in all processes. The results of the study are as follows. First, in both face-to-face and non-face-to-face groups, creative self-efficacy based on creativity classes, as well as its sub-factors, showed significant increases. Second, there was no statistically significant difference in creative self-efficacy and its subfactors between face-to-face and non-face-to-face groups following the creativity classes. The study demonstrated that even if the creativity classes are conducted in a non-face-to-face environment, they could be as effective as face-to-face classes, which suggests that non-face-to-face classes may have potential for creativity education.

관료제 권력 측정: 문재인 정부의 중앙부처를 중심으로

최민지(Min Ji Choi),오재록(Jae Rok Oh) 한국국정관리학회 2024 현대사회와 행정 Vol.34 No.4

본 연구는 관료제 권력 현상을 분석하기 위해 문재인 정부의 44개 중앙행정기관의 상대적인 권력의 크기와 순위를 측정한 결과를 제시하고 있다. 관료제 권력지수(BPI) 측정결과, 기획재정부, 국방부, 교육부, 국토교통부, 산업통상자원부 등의 순으로 그 상대순위가 높게 나타났고, 농촌진흥청, 통계청, 방위사업청, 조달청, 병무청 등의 순으로 낮게 나타났다. 선행연구의 노무현・이명박・박근혜 정부를 대상으로 한 측정결과와 본 연구의 결과를 대조해 보면, 4개 정부 공통으로 기획재정부, 검찰청, 국방부, 국토교통부, 산업통상자원부, 교육부, 국가정보원, 행정안전부 등의 상대순위가 높았고, 법제처, 병무청, 농촌진흥청, 국가인권위원회, 국가보훈처, 조달청, 문화재청 등의 상대순위가 낮게 나타났다. 특히, 진보 정부인 노무현・문재인 정부보다 보수 정부인 이명박・박근혜 정부에서 기획재정부, 검찰청, 경찰청, 국가정보원 등 이른바 ‘권력기관’의 관료제 권력지수와 상대순위가 높게 나타났다. 본 연구의 이론적・실천적 공헌은 관료제 권력기관에 대한 견제와 민주적 통제의 필요성을 일깨워준다는 데 있다. This study presents the results of measuring the relative size and ranking of bureaucratic power among 44 central administrative agencies during the Moon Jae-in administration to analyze the phenomenon of bureaucratic power. The results of the Bureaucratic Power Index (BPI) measurement indicate that the Ministry of Economy and Finance, Ministry of National Defense, Ministry of Education, Ministry of Land, Infrastructure, and Transport, and Ministry of Trade, Industry, and Energy ranked high in relative bureaucratic power, in that order, while the Rural Development Administration, Statistics Korea, Defense Acquisition Program Administration, Public Procurement Service, and Military Manpower Administration ranked low in that order. When compared with the results of previous studies measuring the administrations of Roh Moo-hyun, Lee Myung-bak, and Park Geun-hye, the Ministry of Economy and Finance, Supreme Prosecutors' Office, Ministry of National Defense, Ministry of Land, Infrastructure, and Transport, Ministry of Trade, Industry, and Energy, Ministry of Education, National Intelligence Service, and Ministry of the Interior and Safety consistently ranked high in relative standing across all four administrations. Conversely, the Ministry of Government Legislation, Military Manpower Administration, Rural Development Administration, National Human Rights Commission, Ministry of Patriots and Veterans Affairs, Public Procurement Service, and Cultural Heritage Administration consistently ranked low in relative standing. Notably, the so-called “power agencies,” such as the Ministry of Economy and Finance, Supreme Prosecutors' Office, National Police Agency, and National Intelligence Service, exhibited higher BPI scores and relative rankings under the conservative administrations of Lee Myung-bak and Park Geun-hye compared to the progressive administrations of Roh Moo-hyun and Moon Jae-in. The theoretical and practical contribution of this study lies in emphasizing the necessity of checks and democratic control over bureaucratic power institutions.
