The inception of the knowledge-based society around the year of 2000 began to have a great influence on the types of industry. This new trend signified that culture becomes a driving force in social development. The cultural industry constitutes a part of software which provides contents in raising and cultivating creativity. The categories of cultural industry involve cultural commodities of design and crafts. The importance of immaterial values makes the state cultivate and support cultural industry in the 21 st century. The trade of cultural commodities in the world is dominated by advanced countries which understood the importance of design and culture. The new comers like the Republic of Korea are disadvantaged in terms of resources, sales, circulation, institutions. The innate characteristics of Korean culture are to be emphasized and developed into cultural commodities in order to develop Korean cultural industry in the competitive world. The purpose of this paper is to make an offer of method of the development of cultural design industry by providing theoretical analytical data for achieving state competition in the world market, specially by analyzing the structures of market, distribution and present status in Japan.

By a development of high-advanced science technology, the area of image made inter-area's communication more actively. Such the inter-image exchange facilitated a new combination of areas. By such the development and the activation of public design, the area of image has been extended into the area of environmental design as the public meaning. According to this flow, the media art of using a light has been introduced in the environment of water-front in Korea. Hence, it enhanced the region's identity and gave a special impression to tourists. However, the study on the area of image in the Korean environmental design is still insufficient. Accordingly, the constant expression development absolutely required. For developing and researching a variety of expression techniques, the utilization of media art is expected to work as the alternative of image expression technique.

결혼이주여성의 사회참여가 생활만족도에 미치는 영향 : 연령범주별 비교분석 연구

전혜정(HaeJeong Jeon),백주희(Ju Hee Baek) 한국가족학회 2019 가족과 문화 Vol.31 No.4

결혼이주여성의 양적증가와 함께 이들의 이주기간이 길어짐에 따라 중년기에 접어든 결혼이주여성의 비중도 높아지는 추세이다. 이에 본 연구는 결혼이주여성의 사회참여가 생활만족도에 미치는 영향의 연령범주별(성인기 대 중년기) 패턴의 차이를 규명하기 위해, 2015년 전국 다문화가족 실태조사를 기반으로 성인기 10,886명과 중년기 3,124명을 포함한 총 14,010명의 결혼이주여성을 대상으로 분석하였다. 분석결과, 사회참여(비공식적, 공식적) 수준의 차이에서 성인기 결혼이주여성은 모국인친구모임 참여가 중년기 결혼이주여성보다 높은 반면 중년기 결혼이주여성은 지역주민모임, 종교활동이 성인기 결혼이주여성에 비해 더 높은 것으로 나타났다. 또한, 공식적 사회참여로 경제활동을 하고 있는 결혼이주여성은 성인기 결혼이주여성에 비해 중년기 결혼이주여성이 약 20%가량 높은 편이었으며, 최근 우리나라 여성의 경제활동 참여율과 비교해보아도 매우 높은 수준이었다. 회귀분석에서는 성인기 결혼이주여성은 비공식적, 공식적 사회참여 모든 변수가 생활만족도에 영향을 미치는 것으로 나타났고, 중년기 결혼이주여성은 통제변수인 월평균 소득만이 생활만족도에 영향을 미치는 유의한 변수로 드러났다. 이상의 결과를 바탕으로 결혼이주여성의 연령범주에 따른 의미 있는 사회참여를 발견하여 생활만족도를 향상시킬 수 있는 방안을 제안하였다. As marriage-based female immigrants increase, their local stay is increasing. Accordingly, more and more marriage-based female immigrants are coming into their middle age. So, to verify the differentiation of the age-specific influence (adulthood vs. middle age) that the social participation of those marriage-based female immigrants exert on their satisfaction with their life, this study has performed an analysis on 14,010 marriage-based female immigrants including 10,886 of them in adulthood and 3,124 of them in their middle age, based on the 2015 survey of the multicultural families. The analysis shows that as far as (official or unofficial) social participation is concerned, more of those marriage-based female immigrants in adulthood participated in the meetings of their fellow persons from their native countries than those in their middle age, whereas those in their middle age were more active in the meetings of local residents and religious activities than those in their adulthood. Also, the rate of those marriage -based female immigrants in their middle age who engaged in economic activities through official social participation was about 20% higher than the rate of those in their adulthood, which is a very high level when compared to the latest economic participation rate of South Korean women. The regression analysis showed that for the marriage-based female immigrants in adulthood, all the variables of official or unofficial social participation were significant predictor for life statisfaction, whereas for those in their middle age, the control variable of average monthly income alone significantly influenced life statisfaction. Based on these results, the study suggests a plan to increase the marriage-based female immigrants’ satisfaction with their life by discovering age-specific meaningful social participation.

Acquired resistance to inhibitors of anaplastic lymphoma kinase (ALK) is a major clinical challenge for ALK fusion-positive non-small-cell lung cancer (NSCLC). In the absence of secondary ALK mutations, epigenetic reprogramming is one of the main mechanisms of drug resistance, as it leads to phenotype switching that occurs during the epithelial-to-mesenchymal transition (EMT). Although drug-induced epigenetic reprogramming is believed to alter the sensitivity of cancer cells to anticancer treatments, there is still much to learn about overcoming drug resistance. In this study, we used an in vitro model of ceritinib-resistant NSCLC and employed genome-wide DNA methylation analysis in combination with single-cell (sc) RNA-seq to identify cytidine deaminase (CDA), a pyrimidine salvage pathway enzyme, as a candidate drug target. CDA was hypomethylated and upregulated in ceritinib-resistant cells. CDA-overexpressing cells were rarely but definitively detected in the naïve cell population by scRNA-seq, and their abundance was increased in the acquired-resistance population. Knockdown of CDA had antiproliferative effects on resistant cells and reversed the EMT phenotype. Treatment with epigenome-related nucleosides such as 5-formyl-2′-deoxycytidine selectively ablated CDA-overexpressing resistant cells via accumulation of DNA damage. Collectively, our data suggest that targeting CDA metabolism using epigenome-related nucleosides represents a potential new therapeutic strategy for overcoming ALK inhibitor resistance in NSCLC.

뉴노멀 시대의 건강관리 가전제품 개선점 제안; 정화 시스템 관련 제품 사례 중심으로

박해정 ( Haejeong Park ),김은영 ( Eunyoung Kim ) 한국산업디자이너협회(한국인더스트리얼디자인학회) 2021 산업디자인학연구 Vol.15 No.1

연구배경 최근 코로나 19로 인해 바이러스 위협을 느낀 사람들은 라이프스타일을 변화하기 시작했고 그 변화가 표준이 되며 이를 뉴노멀 시대라고 한다. 새롭게 시작된 뚜렷한 변화 중 하나는 살균 및 소독하는 것이 일상화된 것이다. 이러한 변화를 보아, 향후 위생 관련 인식의 고조로 가전제품 산업에 살균 기능의 필요성이 대두될 것으로 예측된다. 연구방법 먼저 코로나 팬데믹의 심각성에 대해 이론적 고찰을 한다. 다음으로 바이러스로부터 사람들의 건강을 보호하고자 구매하는 건강관리 가전제품과 오염된 공기를 정화하는 시스템에 대한 문헌적 조사를 한다. 이를 통해 건강관리 가전제품들 중 정화 시스템이 접목된 사례를 중심으로 비교 및 분석하여 한계점을 도출한다. 연구결과 현재 판매되는 제품들은 강력한 살균을 위해 사물을 소독하는 제품으로 국한되어 있으며, 에어로졸의 위험성이 있는 공간 소독이 필요하다. 또한, 오염된 공기 정화 시스템은 필터를 통해 유해 물질을 제거하는 청정 방식이 대부분이며 바이러스 제거 목적이라 보기에는 어렵다. 그리고 인력으로 이동시키거나 빌트인이며 수동적이다. 마지막으로 사용성에 있어 건강 보호를 위한 제품인 만큼 신체적 피해가 없어야 한다. 결론 앞서 언급된 한계점에 따르면 향후 중요시될 부분은 공간(Space), 살균(Sterilization), 자력(Self), 안전성(Safety)이 향후 중요시될 방향이며, 이를 ‘4S’라고 축약한다. 4S 개선점을 제안하며, 향후 뉴노멀 시대에 개선되어야 할 건강관리 가전제품의 기초 자료로 활용될 수 있을 것이다. Background Recently, people threatened by COVID 19 have started changing their lifestyle and this change became the norm which is called the Newnormal era. One of these new and changes is that sterilization and disinfection became a routine. Based on this trend, it is predicted that the emerging concern about hygiene will require the need for disinfection function in the home appliance industry. Methods First, a theoretical review of the seriousness of the COVID pandemic was conducted. Next, a literal survey was performed on well-being products purchased to protect people's health from virus and systems that purify contaminated air. Through this, the limitations are drawn by comparing and analyzing the cases of healthcare home appliances that are applying the purification system. Result Currently sold products are limited to products that disinfect objects for a complete sterilization, and disinfecting the areas where contain the risk of aerosol is required. In addition, purification systems for contaminated air mostly remove the harmful substances through a filter, which makes it difficult to say that it is to get rid of the viruses. Also, it's either controlled by human or it’s a built-in and passive. Lastly, as it is for healthcare, there shall not be any physical damages. Conclusion Space, Sterilization, Self, and Safety are mostly the focal points that will be considered as important in the future, and this is abbreviated as '4S'. 4S improvement points are proposed. This could also be used as basic data for the well-being product that will have to be improved in the newnormal era.

황혜정(Haejeong Hwang),유선아(Suna Ryu) 학습자중심교과교육학회 2024 학습자중심교과교육연구 Vol.24 No.2

Objectives The purpose of this study is to analyze research trends in software-enhanced science instruction and to draw implications for teachers' roles and challenges in improving the quality of software-enhanced science instruction. Methods A total of 84 domestic KCI-level academic studies related to software-based science teaching were ex-tracted from RISS, and research trends were analyzed by publication year, research purpose, research subjects, class type, and research topic. Then, we reviewed the role of science teachers in each study and analyzed their roles in the process of planning and running lessons using software and in identifying and solving students' difficulties. Results In the analysis of research trends in science classes utilizing software, studies focusing on the effective-ness of programs and targeting high school students were predominant. In terms of the teacher's role, it was found that teachers play a central role at various stages of the lesson. Teachers are responsible for critical tasks such as designing lessons linked to software use, overcoming technical barriers, anticipating difficulties and providing feedback, as well as monitoring and coaching student achievement. These studies highlight the importance of the teacher's role in science lessons using software, yet reveal a lack of systematic research on specific roles and sup-port methods. Conclusions Teachers' technical skills, understanding of the subject matter, and ability to operate the classroom play an important role in the success of the class. In this regard, teacher training programs should be realistic in terms of content and level, and reflect a deep understanding of the role and support of teachers in order for them to effectively implement software-enhanced lessons. More research is needed to analyze the difficulties teachers face in actual classrooms and the challenges they face in designing lessons. 목적 이 연구의 목적은 소프트웨어를 활용한 과학 수업의 연구 동향을 분석하고, 소프트웨어를 활용한 과학 수업의 질을 향상시키기 위한 교사의 역할과 과제에 대한 시사점을 도출하는 것이다. 방법 RISS에서 소프트웨어를 활용한 과학 수업과 관련된 국내 KCI급 학술 연구 총 84편을 추출하고, 발행 연도, 연구 목적, 연구 대상, 수업 유형, 연구 주제별로 연구 동향을 분석하였다. 이후, 각 연구 내용에서 과학 교사의 역할에 대해 검토하고, 소프트웨어를 활용한 수업을 계획하고 운영하는 과정과 학생들의 어려움을 파악하고 해결하는 과정에서 교사의 역할을 분석하였다. 결과 소프트웨어를 활용한 과학 수업의 연구 동향 분석에서 프로그램 효과와 고등학생 대상 연구가 주를 이루었다. 교사의 역할에 관한 검토에서는 교사가 수업의 다양한 단계에서 중추적인 역할을 수행하는 것으로 나타났다. 교사는 소프트웨어 활용과 연계된 수업 설계, 기술적 장벽 해소, 어려움 예측 및 피드백 제공, 학생 성취 모니터링 및 코칭 등에서 핵심적인 역할을 담당해야 한다. 이러한 연구들은 교사가 소프트웨어를 활용한 과학 수업에서 중요한 역할을 수행해야 함을 제시하면서도, 구체적인 역할과 지원 방법에 대한 체계적인 연구는 부족함을 드러냈다. 결론 소프트웨어를 활용한 과학 수업의 중요성이 증가함에 따라, 교사의 역할도 그 중요성을 더해가고 있다. 교사의 기술적 소양, 교과에 대한 이해 및 수업 운용 능력은 수업의 성공에 중요한 요소이다. 따라서 실제 수업 현장에서 교사가 직면하는 어려움 및 수업을 설계하는 과정에서 겪는 어려움에 대한 분석 연구가 요구되며, 현장 내용과 수준을 현실적으로 반영한 교사 연수 프로그램 등 다양한 지원이 필요하다.
