이 연구의 목적은 인문사회계열 학생을 대상으로 한 교양 과학 수업에서 플립러닝 적용 사례와 함께 교양 과학 교과목의 수업 설계 과정에서 필요한 과학사 내용 체계를 제공하는데 있다. 연구를 위해 기존 운영중인 대학교 교양 과학 수업 및 과학사 수업의 실태를 분석하고, 다양한 선행연구 분석을 통해 플립러닝 방식을 적용한 '과학사의 이해' 교과목을 개발하였다. 과학교양교육의 본질적 목표에 도달할 수 있는 과학사 강의 목표로 지식의 습득과 다양한 역량 강화를 포함함과 함께 과학적 태도 함양을 설정하고 이를 고려하여 15주차의 내용 체계를 설계하였다. 구성된 '과학사의 이해' 내용 체계 중 '과학의 역사' 부분에 해당하는 4개의 주제는 플립러닝으로 수업을 구성하고 온라인 영상자료와 집단 토의 활동을 포함해 교수학습활동을 구성하였다. 인문사회계열 학생을 대상으로 강좌를 개설하고 56명의 대학생을 대상으로 수업을 운영한 결과 학생들의 과학에 대한 흥미와 인식이 높아진 것을 확인할 수 있었다. 이 연구의 사례를 통해 과학사 및 교양 과학 교육에 대한 교육적 시사점을 제공하였다.

Purpose: Arts and cultural management are a field with unique meaning and significance. This study is uniquely based on the focus of arts and cultural management on social and cultural sustainability sets it apart from other related study fields. Through delving into arts and cultural management, one can quickly gain skills vis-à-vis creativity and innovation in traditional and emerging media platforms. Research design, data and methodology: The current researcher relied on the descriptive research design, arriving at and evaluating the findings. The descriptive research design was the most ideal because of the need to evaluate the various literature sources systematically and later describe them without undue influence. Results: This research's core finding of art and cultural management in the current literature may be split up four findings, such as (1) Art and Cultural Management is Fast Embracing Digital Innovations and Related Elements, (2) Data and Analytics in Art and Cultural Management, (3) Interdisciplinary Nature of Arts and Cultural Management Elements, and (4) Arts and Cultural Management Face Numerous Challenges that Define it and its Future. Conclusions: All in all, based on the literature findings, the present research concludes that It is incumbent upon the various stakeholders, such as the government, to prioritize the arts and cultural management field through adequate budgeting and allocation of money.

In the present study, nanocrystalline mixed metal oxide, $CuMnO_3$ catalyst have been synthesized by mechanochemical method with green chemistry approach. The synthesized catalyst was characterized by analytical techniques including FTIR, XRD, SEM, TEM and BET surface area. The synthesized catalyst shows high surface area is $121.06m^2/g$ with particle size 18 nm. The one pot four component synthesis of substituted 2-phenyl-4(3H) quinazolinone from the reaction of anthranilic acid, benzoyl chloride, hydrazine hydrate and substituted benzaldehyde in presence of $CuMnO_3$ nanocatalyst has been carried out. It affords the corresponding products with high yield (76-95%) in very short reaction time. All the obtained products were characterized with $^1HNMR$, $^{13}CNMR$, FTIR and EIMS.

This article highlights the importance of design in the formation of worldview paradigms in global culture. The research aims to investigate the design development as a part of the culture and its significance in the social development of society and worldview standards. The article uses general scientific methods of cognition, showing the transformation of design in the social and cultural sphere based on scientific and business literature. The research results show the chronology of design development as a factor determining the development of society and its worldview. In particular, the epoch of modernism, classical functionalism, postmodernism, post-industrialism, and digital design show their own particularities of design development. Furthermore, the article reveals the peculiarities of design development and its requirements depending on the development of society, progress, and civilization in general. The question of current and future trends in the development of design as a factor of worldview paradigms in the culture is based on digitalization, globalization, and the formation of design as an independent entity that determines man's place in the world and society.

Vanillic acid, a vegetable phenolic compound, is a strong antioxidant. The aim of the present study was to determine its effects on mitomycin C-induced DNA damage in human blood lymphocyte cultures in vitro, both alone and in combination with mitomycin C (MMC). The cytokinesis block micronucleus test and alkaline comet assay were used to determine genotoxic damage and anti-genotoxic effects of vanillic acid at the DNA and chromosome levels. MMC induced genotoxicity at a dose of $0.25{\mu}g/ml$. Vanillic acid ($1{\mu}g/ml$) significantly reduced both the rates of DNA damaged cells and the frequency of micronucleated cells. A high dose of vanillic acid ($2{\mu}g/ml$) itself had genotoxic effects on DNA. In addition, both test systems showed similar results when tested with the negative control, consisting of dimethyl sulfoxide (DMSO) in combination with vanillic acid ($1{\mu}g/ml$)+MMC. In conclusion, vanillic acid could prevent oxidative damage to DNA and chromosomes when used at an appropriately low dose.
