( Eunjoo Cho ),( Euna Lee ),( Eun Young Kim ) 생화학분자생물학회(구 한국생화학분자생물학회) 2016 BMB Reports Vol.49 No.11

The circadian clock system enables organisms to anticipate the rhythmic environmental changes and to manifest behavior and physiology at advantageous times of the day. Transcriptional/ translational feedback loop (TTFL) is the basic feature of the eukaryotic circadian clock and is based on the rhythmic association of circadian transcriptional activator and repressor. In Drosophila, repression of dCLOCK/CYCLE (dCLK/CYC) mediated transcription by PERIOD (PER) is critical for inducing circadian rhythms of gene expression. Pacemaker neurons in the brain control specific circadian behaviors upon environmental timing cues such as light and temperature cycle. We show that amino acids 657-707 of dCLK are important for the transcriptional activation and the association with PER both in vitro and in vivo. Flies expressing dCLK lacking AA657-707 in Clkout genetic background, homologous to the mouse Clock allele where exon 19 region is deleted, display pacemaker-neuron-dependent perturbation of the molecular clockwork. The molecular rhythms in light-cycle-sensitive pacemaker neurons such as ventral lateral neurons (LNvs) were significantly disrupted, but those in temperature-cycle-sensitive pacemaker neurons such as dorsal neurons (DNs) were robust. Our results suggest that the dCLK-controlled TTFL diversify in a pacemaker-neuron-dependent manner which may contribute to specific functions such as different sensitivities to entraining cues.

DO YOUNG CONSUMERS CARE ABOUT COUNTRY-OF-ORIGIN OF LUXURY FASHION BRANDS?

Eunjoo Cho,Steven W. Kopp,Sabrina Heix 글로벌지식마케팅경영학회 2020 Global Marketing Conference Vol.2020 No.11

The luxury market has become a prevalent global economic sector which is estimated to reach $442 billion by 2025 (Arienti, Levato, Kamel, & Montgolfier, 2018). Sales revenue in the luxury market has grown not only in the US and EU, but also in emerging economies with rapid economic expansion, such as China and India (Shukla, 2010; Tynan, McKechnie, & Chhuon, 2010). Young consumers (i.e., millennials and Gen Z) comprise the fastest growing group of purchasers of luxury goods (D’Arpizio, Levato, Prete, Del Fabbro, & de Montgolfier, 2019). Subsequently, marketers are interested in factors that affect young consumers’ decision-making process in luxury fashion goods consumption. It is a challenge for marketers to appeal to young consumers because abrand or brand name is less important to them than it has been for older generations (Forte, 2019). Country-of-origin (CoO) is relatively important for luxury purchase compared to non-luxury purchase (Godey et al., 2012). In the context of luxury brand consumption, research suggests that attitude functions (social-adjustive, value-expressive, hedonic, and utilitarian) also have an impact on luxury purchase intentions (Schade, Hegner, Horstmann, & Brinkmann, 2016). This study thus investigates significant factors influencing luxury brand purchase among young consumers. Specifically, we draw from “Functional Theories of Attitudes” (Grewal, Mehta, & Kardes, 2004) as a framework to investigate the effects of CoO on consumers’ attitude functions and luxury brand purchase intentions.

The effect of social connectedness on consumer adoption of social commerce in apparel shopping

Eunjoo Cho,Jihyeong Son 한국의류학회 2019 Fashion and Textiles Vol.6 No.1

The purpose of this study is to examine the effect of social connectedness on social media users’ attitudes and intentions towards adopting social commerce in the technology acceptance model (TAM). Data collected from young adult social media users (n = 446) in the US support the proposed model. A structural equation model shows that social connectedness positively influences social media users’ perceptions of ease of use, usefulness, and enjoyment, which in turn, influence their attitudes and intentions towards adopting social commerce in apparel shopping. The impact of social connectedness is stronger on perceived ease of use than other TAM variables. Perceived enjoyment has the strongest impact on attitudes, and attitudes strongly influence consumer intentions for adopting social commerce for apparel purchases. Results of this study reveal that social connectedness enhances social media users’ perceptions of social commerce and positively leads to the adoption of social commerce in apparel shopping. Findings indicate that social connectedness has an indirect effect on attitudes towards social commerce through utilitarian (i.e., ease of use and usefulness) and hedonic (i.e., enjoyment) perceptions of social commerce. These findings highlight the importance of social connectedness through utilitarian and hedonic perceptions in enhancing consumers’ adoption of social commerce for purchasing apparel products.

한국인과 한국어 학습자의 인사 화행 연구

조은주 ( Eunjoo Cho ),고은정 ( Eun Jung Ko ) 이중언어학회 2015 이중언어학 Vol.60 No.-

The speech act of greeting performs a phatic function and, therefore, is crucial in fluent communication. For that reason, it is important for L2 learners who study a foreign language to fully understand the subject. However, so far, no systematic research has been conducted with respect to the speech act of greeting in Korean language education. Both the speech act of greeting among Korean language learners and that among Korean native speakers have been rarely studied. While many researchers have attempted to classify and analyze expressions of greeting in Korean language, the majority of them relied on their intuition or unreliable data such as TV shows, and, even if authentic materials were used as data, the studies rarely involved a reliable analysis framework. The purpose of this study was to classify types of strategies used in the speech act of greeting among Koreans, and examine specific expressions in each type of the strategies, which were, then, compared to similar data collected from Korean language learners in order to demonstrate the difference in the speech act of greeting between the learners and Korean native speakers. This study is valuable in that it provides systematic classification and examination of strategies and specific expressions used in the speech act of greeting in Korean language, which did not receive much attention in previous research, and also collected authentic data based on a survey. In addition, it demonstrated that there is difference in using the greeting strategies between Korean language learners and Korean native speakers, and that some specific expressions used by the former include elements that are potentially problematic.

박태원 초기 단편의 ‘환상성’ 연구 - 소외 극복의 방법으로서의 환상성을 중심으로

조은주(Cho, Eunjoo) 순천향대학교 인문학연구소 2020 순천향 인문과학논총 Vol.39 No.4

박태원의 초기 단편에서 주체는 ‘이상화된 자아상’을 설정하고 그와의 ‘동일시’를 통해 파편화된 자아의 모습을 재구성한다. 때로는 극도의 외로움과 고독 속에서 자신과 똑같은 처지에 놓인 위무자로서의 ‘분신’을 불러내어 현실에 대응하기도 한다. 분신이 소유한 특별한 ‘놀이’의 세계는 억압적인 현실을 전복하는 기능을 담지하고 있으며 은유적으로는 ‘글쓰기’를 의미한다. 한편 주체가 소외 상황을 타자를 향한 욕망을 통해 극복하려 할 경우, 이때 타자는 대부분 ‘여성’으로 제시된다. 욕망의 대상인 여성이 주체의 세계로 편입되지 않고 주체의 욕망에 응하지 않을 경우, 여성은 악마적 존재로 표상되는 경향을 보인다. 주체는 타자를 ‘악’으로 규정함으로써 자신의 세계를 확고히 구축하려 시도한다. 박태원의 초기 단편에서 ‘환상성’은 소외된 주체가 자신의 한계 상황을 극복하기 위해 택한 하나의 전략이며 주체의 욕망에 의해 기획된 것들이다. ‘환상성’은 무엇보다도 박태원이 글쓰기를 통해 세계를 인식하는 하나의 방법론의 차원이자 언어를 통해 세계를 구성하는 시도와 연결되어 있다는 점에서 중요하다. 이러한 관점은 박태원의 초기 모더니즘적 경향과 후기 역사소설의 창작을 총체적으로 이해할 수 있는 중요한 계기가 될 수 있을 것이다. In the early-year short stories written by Park Taewon, the protagonists imagine an “idealized self” and reconstruct their fragmented self by identifying with their idealized self. At times of extreme loneliness and solitude, they summon their “alter ego” who is put in the same situation to act as a comfort to overcome their present reality. The special ‘amusement’ world held by these alter egos subverts the oppressive reality, and it can be seen as a metaphor for the act of writing. When the protagonists try to overcome their isolated state with a desire for others, in most cases, the object of this desire is women. When these women are not bought into the protagonists’ world and refuse to respond to their desire, they are seen as demonic. Moreover, the protagonists see others as evil in an attempt to establish their own worlds more firmly. In the author’s stories, fantastic elements work as a strategy for marginalized protagonists to overcome their critical situations and, as such, are conjured based on the protagonists’ desires. Above all, fantastic elements can be seen as one of the author’s ways of perceiving the world through writing, and they are important as they are tied to the author’s attempt to construct a world based on language. Moreover, such fantastic elements provide an important tool to broadly understand the works of Park Taewon, including both his early-year modernist novels and later historical novels.

인구의 자연성과 통치 테크놀로지

조은주(Eunjoo Cho) 한국인문사회과학회 2014 현상과 인식 Vol.38 No.4

이 글은 1968년에 대한가족계획협회의 주도로 조직된 후 1977년 새마을부녀회로 통합되기까지 9년간 지속된 가족계획어머니회에 관한 연구이다. 가족계획어머니회는 가임여성들의 피임실천을 조직하기 위해 법정 리·동 단위에 만들어진 전국 규모의 지역 여성조직이었다. 대한가족계획협회의 공식간행물 및 주요 인물들의 회고에서 가족계획 사업의 성공을 가져온 핵심 요인으로 지목될만큼 가족계획어머니회는 가족계획 사업의 주요한 일부였다. 가족계획어머니회의 조직 및 운영, 각종 조사사업에 대한 분석을 통해 이 연구는 1960-70년대 한국에서 전개되기 시작한 통치의 테크놀로지에 주목한다. 가족계획어머니회를 둘러싼 다기한 통치의 실천들은 인구집단에 내재된 변수와 속성들을 보다 정확하게 계측하고 분석함으로써 이를 변형시키는 요인과 기술을 찾아내는 문제가 이 당시 중요하게 부상하였음을 드러낸다. 이는 주권자-신민의 관계로 환원되지 않는 통치 대상으로서 인구의 등장, 그리고 주권자의 권력으로 완전히 환원되지 않는 이른바 통치성의 등장이 이 시대에 이루어졌음을 보여주는 것이다. This study focuses on the family planning Mothers’ Clubs, which had been organized by the Planned Parenthood Federation of Korea (PPFK) in 1968 and operated until 1977 when the Clubs were integrated into Saemaul Women’s Clubs. The Mothers’ Clubs were local organizations of childbearing-aged women at the legal Li and Dong levels, and aimed at stimulating and encouraging the practice of contraception by women in rural areas. The Mothers’ Clubs were essential for the Family Planning Program; official publications of the PPFK as well as main leaders of the program pointed it out as a core factor that brought about the successful outcome of the program. This study pays special attention to South Korea’s technological advances during the program while analyzing the organization, operation and various research projects of the Mothers’ Clubs. Various governmental practices surrounding the Mothers’ Clubs reveal that it emerged as an important issue?finding out technologies and mechanisms to transform the population through measuring and analyzing accurately. This shows the emergence of the population as the target of government/governing, which cannot be reduced to the relationship between sovereign and subjects. It also shows governmentality appeared in the era, which is not to be reduced sovereign power.

발전국가와 젠더 ―통치의 성별화, 성별화된 주체화

조은주(Eunjoo Cho) 역사비평사 2021 역사비평 Vol.- No.134

The theory of the developmental state that explains the economic development of South Korea has made the state an entity separate from society. However, the state is not an actor with a conscious intent, but is rather an effect of multi-layered practices and actions. This essay approaches the state as power that structures the field of possible actions and demonstrates that gender is the pivot in the developmental state regime in South Korea. The governmentality of the developmental state subjectified individuals as entirely gendered beings, in which women pursued the accomplishment of modern life via their family. The gendered division of labor was the basis of the developmental state, which has dissolved as gendered subjects are transformed into degendered subjects in a neoliberal society.

인구통계와 국가형성

조은주(Eunjoo CHO) 한국사회학회 2014 韓國社會學 Vol.48 No.5

이 논문은 1960년대에 시행된 두 차례의 인구센서스를 통해 한국의 국가형성 과정에 접근한다. 인구센서스는 통치에 필수적인 앎의 장치이자 근대적 행정체계의 일부로서 국가형성의 중요한 요소다. 특정 시점에 완료되는 것이 아닌 과정으로서의 국가형성은 근대적 국가통계로서 인구센서스가 체계화되고 제도화되는 역사적 과정과 긴밀히 결합된다. 1960년과 1966년의 인구센서스는 발전된 통계기법과 자료처리 기술의 도입, 통계업무를 관장하는 강력한 중앙집중적 행정기구 등 근대국가의 통치 테크놀로지와 결합하면서 발전하였다. 이 과정은 일제 식민 지배가 남긴 잔영 위에서 미국과 국제 원조기구의 개입을 통해 전개된 것이었으며, 당시 대한민국에 가해지던 인구조절의 압력과 결합되어 있었다는 점에서 한국 국가형성의 포스트식민성(postcoloniality)의 측면을 드러낸다. 신생독립국인 대한민국은 1960년대를 지나면서 비로소 하나의 완결적 정체(polity)로 인식되기 시작했고, 인구센서스는 정치적 공동체 및 그 구성원의 범주에 대한 상상을 반영하는 동시에 이에 영향을 미쳤다. 1960년대 센서스는 인구를 노동력의 차원에서 포착함으로써 경제발전 및 근대화와 인구를 결합시켰고, ?풍부한 인구?가 아닌 정확한 계측의 차원에서 인구를 국력의 원천으로 사유하도록 이끌었다. 인구센서스를 비롯한 근대적 국가통계의 확립은 ?읽히는? 대상인 사회와 ?읽는? 주체인 국가의 분리를 가져왔다. 국가와 독립적인 ?사회?, 사회의 실제를 파악하고자 하는 ?국가?를 실재적 실체로 인식하는 것은 인구센서스를 비롯한 통치화의 효과이며, 이런 점에서 인구센서스는 근대국가의 통치와 테크놀로지를 결합시켰을 뿐만 아니라 국가-사회의 관계에 대한 자유주의적 사고를 구성하는 중요한 요소가 되었다고 할 수 있다. This paper analyzes the development of South Korean population statistics that is connected to state formation, with the cases of population censuses that were implemented in the 1960s. The modern state, which is centralized, exercises coercion and has hegemony in a given territory, is not completed at a specific moment. It is formed through a continuing structural transformation. The population census is a crucial factor that constitutes a part of the modern administrative and knowledge systems necessary for government. Population censuses in 1960 and 1966 show the historical process in which modern governmental statistics was systemized and institutionalized. They also show the process and the characteristics of establishment as a complete polity of the Republic of Korea that experienced liberation from colonial rule, division, government establishment and the Korean War. The population began to be approached as a labor power for economic activities and recognized as the root of state power, not through the quantitative property of ‘populousness’ but through the accuracy of a ‘precise’ population. Contributing to bureaucratic practices of a modern state and the establishment of organizations and institutions, the population census was combined with introducing and implementing modern technology. It was deployed on the traces of colonial history and, moreover, involved with direct and indirect intervening of the West, especially the US, on which appeared the characteristics of postcolonial state formation.

인구의 출현과 사회적인 것의 구성

조은주(Cho, Eunjoo) 비판사회학회 2015 경제와 사회 Vol.- No.105

이 논문은 인구 개념을 중심으로 사회 혹은 사회적인 것(the social)의 인식에 접근하는 연구다. 인구는 18세기 서구에서 사회(적인 것)에 대한 특정한 사유방식과 결합하면서 등장한 개념이었다. 또 다른 근대적 개념인 시민과 마찬가지로 인구는 인간을 추상화하지만, 추상화를 통해 이질적 존재들인 개인들 사이의 등가성을 확립하고 이 등가성에 기반을 두고 개인적 변이들을 넘어서는 규칙성을 포착하고자 한다는 점에서 특징적이다. 고유의 리듬과 규칙성을 가진 통계적 구성물로서 인구는 사회(적인 것)의 인식에 자연(nature)을 도입하는 중요한 기제가 되었다. 인구는 외재적 개입을 통해 강제할 수 없는 내재적 동인을 가지는 것으로, 역사 전개의 법칙에 따라 사회가 진보한다는 사유와는 완전히 이질적인 사회인식을 가져왔다. 특히 인구에 내재된 자연성을 포착하고 이를 조절하는 문제가 긴요해지면서 인구 변동의 요인과 기술에 대한 앎의 중요성이 부각되었고, 이로써 사회(적인 것)에 대한 전문적이고 과학적인 지식체계는 사회(적인 것) 자체를 구성해내는 실천의 영역이 되었다. 근대 정치에 대한 비판적 논의를 지배해왔던 ‘지배-시민-주권’의 계열에서 사회 혹은 사회적인 것은 국가 대 사회, 국가-사회-시장과 같은 지형학적 범주로 인식되지만, 이와 이질적인 근대 정치의 계열로서 ‘통치-인구-안전’의 계열은 사회 혹은 사회적인 것이 지식과 실천을 통해 지속적으로 구성되는 것임을 보여준다고 하겠다. This paper approaches a stream of recognition of the social through the concept of population. The concept of population began to appear in the West in the eighteenth century, combined with the emergence of a specific form of thinking of the social. Like another modern concept of citizens, population makes people into abstract entities. But the concept of population is distinctive in that through this abstraction, it establishes equivalences among individuals who are heterogeneous and aims to grasp its regularity beyond individual variations. As a statistical construction with its own rhythm and regularity, population became an important instance of introducing nature into the recognition of the social. Operating according to an inherent natural mechanism that cannot be forced by external intervention, the concept of population brought about a substantially different way of thinking about society, compared to thinking of it as progressing along with the law of history. Particularly as it became important to grasp and analyze the inherent agents and techniques of population transformation in order to regulate or modify the naturalness of population, the importance of scientific and professional knowledge has been magnified. Contrary to the series of ‘rule-citizen-sovereignty’ on which discussion about modern power and politics has almost exclusively focused, and in which the social was approached in a topographical way of state vs. society, the series of ‘government-population-security’ which has been deployed in mundane administrative reality shows how the social is constructed through various practices, including knowledge production.
