팩트체크 뉴스 노출, 영향력 인식, 공유 행동에 대한 탐색적 연구

백영민,김선호 한국언론학회 2017 한국언론학보 Vol.61 No.6

최근 확산되고 있는 팩트체크 저널리즘은 사실보도라는 전통적 객관주의 저널리즘을 넘어 언론이 사실검증자의 역할을 수행하는 새로운 저널리즘 양식으로서 주목받고 있다. 팩트체크 저널리즘의 확산에도 불구하고 수용자의 규모와 특징, 그리고 팩트체크 기사의 영향력에 대한 경험적 연구는 아직 부족하다. 본 논문은 설문조사를 통하여 지난 19대 대통령 선거 기간 팩트체크 기사를 접했던 유권자의 특성이 무엇인지 탐색적으로 살펴보았다. 그리고 ‘제3자 효과’ 연구를 기반으로 자신에 대한 팩트체크 뉴스 영향력 인식(제1자 인식)과 다른 유권자에 대한 인식(제3자 인식)을 비교했다. 또한 제1자 인식과 제3자 인식이 담론적 정치참여라고 할 수 있는 팩트체크 뉴스 공유행동에 어떠한 영향을 미치며, 이 관계가 팩트체크 수용자의 정치성향과 가짜뉴스 심각성 인식 수준에 따라 어떻게 달라지는지 살펴보았다. 분석결과 팩트체크 뉴스를 접해본 사람들은 더 젊고, 정치지식과 정치참여도가 높으며, 뉴스를 더 자주 접하며, 정치적으로는 진보적 성향을 띄며 가짜뉴스를 더 심각하게 받아들이는 특징들을 갖고 있었다. 한편, 제3자 인식이 제1자 인식보다 강하게 나타나는 ‘제3자 효과’가 나타났지만, 제3자 인식보다 제1자 인식이 팩트체크 뉴스공유 행동에 더 큰 효과를 미치는 것으로 나타났다. 또한 상호작용 효과의 경우, 제1자 인식과 팩트체크 뉴스 공유행동의 관계는 정치적으로 보수적 응답자에게서 더 약하게 나타났다. 반면 제3자 인식과 팩트체크 뉴스 공유행동의 관계는 가짜뉴스의 심각성 인식수준이 높고 정치적 보수주의 성향이 높은 응답자에게서 더 강하게 나타났다. 연구결과를 토대로 팩트체크 저널리즘이 어떠한 학술적․실천적 함의를 갖는지 논의했다. Fact-check journalism is diffusing into newsrooms along with growing concerns about fake news. Despite its popularity and importance, empirical studies on audiences’ reception of fact-check news have been scant. This study, by analyzing national survey data of voters in the 19th Presidential Election in Korea, attempts to explore socio-economic status of fact-checking news consumers, and their perceptions of presumed influence and sharing behaviors. First, we found that fact-checking news consumers are younger and more progressive, and tend to think fake-news more threatening. Second, we found that fact-checking news consumers’ perception on presumed fact-checking news’ decision effect on other people (i.e., presumed effect on others) is smaller than that on themselves (i.e., presumed effect on self), which attests the third person effect with fact-check news. Third, our findings indicate that sharing of fact-check news is more driven by the presumed effect on self rather than the presumed effect on others. Interestingly, the positive relationship between the presumed effect on self and sharing behavior becomes augmented among those who have progressive ideology, and shrinks among those who have conservative ideology. Additionally, the positive relationship between the presumed effect on others and sharing behavior becomes stronger, when people perceive fake-news as threatening to democracy. Theoretical and practical implications of our findings are discussed.

Interfacial and Mechanical Properties of Carbon Fiber Reinforced Polycarbonate (PC) Film and PC Fiber Impregnated Composites

백영민,신평수,김종현,박하승,K. Lawrence DeVries,박종만 한국섬유공학회 2019 Fibers and polymers Vol.20 No.11

Currently, continuous polymer fibers are usually manufactured in versatile forms such as, aramid fiber. In thisstudy, continuous polycarbonate (PC) fiber having the uniform diameter was manufactured from a thermoplastic PC resinusing a twin screw extruder. Carbon nanotubes (CNTs) were uniformly dispersed in the PC resin, using a solvent dispersionmethod. The effect of CNT on the mechanical properties of PC fiber was analyzed statistically, using Weibull distribution, bysingle PC fiber tensile test. Dynamic contact angle was measured to compare the surface energies of PC fiber and PC-CNTfiber on the water droplet. The difference in the wetting patterns was also observed by injecting a solvent between two fibers. Tensile strength and Young’s modulus of the PC fiber was significantly increased by the addition of even a small amount ofCNT. This improvement can be attributed to the excellent reinforcing and stress transferring effects of the CNT filler. Composites were made of both types of PC film and PC fiber as a matrix and their impregnation properties were investigatedby inspection of photographs of their cross-sections. The mechanical properties of the two-types of composites were alsocompared by tensile testing. From the cross-sectional fractography and the permeated PC weight, PC fiber type exhibitedbetter impregnation property than the PC film type, and thus resulted in the improved tensile strength.

외신보도노출은 어떻게 한국인의 국가자부심을 고양시키는가? : 한국에 대한 해외관심인식의 매개효과를 중심으로

백영민 한국정치커뮤니케이션학회 2024 정치커뮤니케이션 연구 Vol.0 No.73

본 연구에서는 국내 언론수용자의 한국관련 외신보도노출에 따라 한국에 대한 해외의 관심수준을 어떻게 다르게 인식하며, 이에 따라 수용자의 국가자부심이 어떻게 고양되는지 살펴보았다. 외신보도 관련 국내외 선행연구 결과를 토대로, 본 연구에서는 한국관련 외신보도노출을 ‘국내언론을 통해 간접적으로 접한 외신보도노출’(간접노출)과 최근 새롭게 등장・확산한 ‘수용자 스스로 찾아본 외신보도노출’(직접노출)로 구분하였으며, 두 가지 경로의 외신보도노출 수준에 따라 해외국가들이 얼마나 한국을 주목하며, 이에 따라 정치・경제・사회・문화 등을 아우르는 12개 영역에서 한국을 얼마나 자랑스럽게 생각하며, 전반적으로 한국에 대한 긍정적 감정수준은 어떠한지 살펴보았다. 연구결과 국내 언론수용자의 직접 외신보도노출이 빈번할수록 해외국가에서 한국을 주목한다는 인식이 강하게 나타났으며, 이러한 인식은 국가자부심 고양으로 이어졌다. 그러나 간접 외신보도노출에서는 별다른 효과가 발견되지 않았다. 본 연구에서는 해외 언론보도가 국내 언론수용자에게 어떠한 영향을 미치는지 살펴봄으로써 미디어효과 발생의 범위를 확장하였고, 한국인의 국가자부심 형성과정에서 한국에 대한 해외평가가 중요한 역할을 수행한다는 점을 실증적으로 확인할 수 있었다. This study investigates how Korean news audience's exposure to foreign news report on Korea influences their presumed foreign attention on Korea, which, in turn, affects their national pride. Based on a critical literature review of foreign news media usage, foreign news exposure is classified into both direct exposure (i.e., the audience's exposure to foreign news based on their own selection) and indirect exposure (i.e., the audience's exposure to foreign news cited by local media). Additionally, this study divides national pride into two types: domain-specific national pride, which pertains to politics, economics, culture, and other domains, and general national pride. Results revealed that the Korean news audience's direct exposure to foreign news reports on Korea increases their presumed foreign attention on Korea, which in turn influences both domain-specific and general national pride. However, the audience's indirect exposure to foreign news does not affect their presumed foreign attention on Korea, nor does it influence either domain-specific or general national pride. This study expands the scope of journalism studies by examining how foreign news media influences the perception of the local news audience regarding their own country. It empirically supports the notion that Korean perceptions of foreign attention on Korea serve as an important factor contributing to national pride in Korea.

Mucormycosis is a rare opportunistic infection caused by fungi of the order Mucorales that typically occurs in patients with diabetes or immunocompromised state. Rhino-orbital-cerebral mucormycosis is the most common type, often has a life-threatening outcome. Mucormycosis has specific vascular tropism complicating mucorthrombosis or mycotic aneurysm. We report a diabetic patient presenting with ophthalmoplegia, orbital necrosis, and contralateral hemiparesis, who suddenly progressed to coma and died of subarachnoid hemorrhage due to the rupture of mycotic aneurysm in distal internal carotid artery.

Investigation of Interfacial and Mechanical Properties of Various Thermally-Recycled Carbon Fibers/Recycled PET Composites

백영민,신평수,김종현,박하승,권동준,K. Lawrence DeVries,박종만 한국섬유공학회 2018 Fibers and polymers Vol.19 No.8

The mechanical and interfacial properties were evaluated for carbon fiber reinforced composites (CFRC) manufactured using thermally recycled waste carbon fiber and recycled polyethylene terephthalate (PET). The mechanical properties of the recycled fiber were determined and compared to those of neat fibers using the single-fiber tensile test. The surfaces of the recycled and neat carbon fiber were examined and compared using FE-SEM and dynamic contact angle measurements. A goal of the study was to determine the applicability of industrial use of recycled CF and/or recycled PET in CFRC. Mechanical properties were measured using short beam and tensile tests. These properties were observed to be correlated with crystallinity. The interfacial properties between the recycled carbon fibers and recycled PET were evaluated using the microdroplet test. At low temperature residual resin remained on the recycled CFs surface resulting relatively the low interfacial properties. At excessively high temperatures, oxidation occurred, on the CFs surface, which also resulting in relatively poor low mechanical properties. The optimal treatment condition was 500 oC, where the surface was relatively clean and the reduction in mechanical properties was minimized.

Korean-Americans in Transition - Decade of Rationality, Plurality, Economic Growth, and Korean Wave -

백영민 한국실천신학회 2014 신학과 실천 Vol.0 No.40

This article explores the radical changes that South Korea have gone through in the last decade, and how these changes, in turn, have influenced and reshaped Korean American communities in the United States of America, especially within Korean-American immigrant churches and their views, and understanding of the new generations. It examines what is needed within Korean American immigrant communities and their churches in three-fold dimensions. First in the philosophical aspect, the emphasis of rationality and postmodern plurality becomes evident and challenges irrationally-enforced Christian belief in the traditional immigrant churches. New generations educated by critical rationality and pluralistic inclusiveness will not honor the current exclusiveness. Second, the transitions of the Korea’s rapid economic developments and the upgraded economic status of Korean-American immigrants challenge the ultimate goal and meaning of people’s spiritual life. The traditional and typical message of church focusing on individual survival and prosperity needs to be transformed with the message of community service and responsibility. Third, the cultural transition of the Korean wave, called Hallyu, unexpectedly but powerfully changed the Korean-American identity, especially the view their own Korean heritage. Postmodern anti-authoritarianism requires that the traditional single, authoritative, and top-down leadership paradigm needs to be transformed into mutual, inclusive, and communal leadership. The new paradigm of digital communication accelerates and actualizes these transitions into the physical lives of Korean-Americans. The churches are required to be contextually relevant to and responsible for these powerful transitions and to claim the meaning and mission of its existence for the Korean-American immigrant community.
