마이그레이션 이론을 적용한 유튜브로의 소비자 정보채널 전환에 관한 연구

백지연,이진명 한국소비자학회 2023 소비자학연구 Vol.34 No.4

The purpose of this study is to identify the current status of YouTube use as a consumer information search channel and to identify the behavior of switching information channels from portal sites to YouTube. By applying migration theory as a theoretical framework, the perceived benefits of YouTube were adopted as pull factors, the perceived risks of portal sites were adopted as push factors, and conversion costs were adopted as mooring factors to predict consumers' information channel switching behavior. An online survey was conducted on adults in their 20s to 50s who had experience using YouTube within the last month, and a total of 312 data were collected and analyzed by applying t-test, ANOVA, and multiple regression analysis. The main results of this study are as follows. First, YouTube was found to be the most used information channel by consumers in the purchasing process. It was followed by portal sites, online price comparison sites, manufacturer sites, and SNS in that order. Second, as a result of surveying consumers' perceptions of online information channels, the level of commerciality of portal site contents was high. This suggests that consumers perceive portal sites as a source of commercial information due to C2C information generated by many online advertisements and corporate sponsorship. The usability of YouTube's content and the level of personalization were high, which can be seen as a relative advantage of YouTube as a source of consumer information. Third, as a result of multiple regression analysis, it was found that YouTube's content usefulness and information source trust, as well as portal site's platform distrust and content commerciality, had a significant positive effect on the consumer information channel conversion from portal site to YouTube. The effect of conversion cost was found to be negative, indicating that time and effort costs impede the conversion of information channels from portals to YouTube. This study is meaningful in that it demonstrates the importance of YouTube as a consumer information channel and provides useful implications for improving information channels by identifying factors that affect consumers' conversion of information channels from portal sites to YouTube.

백지연,나경희 한국외국어교육학회 2018 Foreign languages education Vol.25 No.2

The purpose of this study is to investigate error patterns in EFL college students’ English writing as well as their change over time, based on the teacher’s feedback. In order to accomplish this purpose, two research questions were constructed; first, what are the characteristics of Korean EFL students’ writing based on the maturity of English sentence by the T-unit analysis? Second, what types of error patterns are produced in Korean EFL students’ writing? Also, how do the error patterns change based on the teacher’s feedback over time? The participants were four Korean EFL college students, and they were asked to pre-write, draft, revise and edit until they completed their final draft. The results of pre- and post-writing test were also analyzed. The major findings are as follows: 1) The mean number of T-unit among participants was 42.25 units, and the mean number of words per T-unit was 10.95 words. 2) The most frequently committed errors were found out as lexical and morphological errors. Moreover, the rate of lexical and sentence structure errors has been dropped, whereas the rate of punctuation errors has increased as the teacher’s feedback progressed over time. Pedagogical and practical suggestions are also made on the effective teaching of English writing in Korean classroom settings.

메모리얼 공간에서의외상 후 성장(PTG) 경험 분석 연구-세월호 참사와 4.16기억전시관 기증자를 중심으로-

백지연,권지연 한국박물관학회 2022 博物館學報 Vol.- No.44

Unforeseen natural and social disasters are increasing every year with the advent of climate change, armed conflicts, and social disruptions in the world. The Global Assessment Report (GAR2022) by the UN Office for Disaster Risk Reduction (UNDRR) revealed that 350 to 500 disasters took place every year over the past two decades. In this light, memorials are becoming increasingly important public spaces where the community can partake in the pain of the tragedy, heal from the trauma experienced by the community, and recover from the divided society to build a healthier future. This study focuses on the April 16 Memorial Exhibition Hall that commemorates the victims of the Sewol Ferry Incident of 2014. 304 among 476 on board were lost during this incident, the majority being highschool students in their teenage years. This tragedy shook the nation in its entirety, and many who witnessed the event suffered from indirect posttraumatic symptoms such as insomnia, anxiety, depression, and helplessness. An in-depth interview of five donors of artworks to this memorial hall revealed that all of them experienced positive changes as the result of their social interaction with other participants, families of victims, and visitors at the exhibition hall. Through self-disclosure and social support, the donors experienced positive changes in self-perception, life outlook, and relation to others. These changes ultimately correspond to the model of posttraumatic growth proposed by Tedeschi and Calhoun. As such, interactive memorial spaces can provide posttraumatic growth for the community that experienced trauma. 현대 메모리얼 뮤지엄은 비극적 사건으로 인해 발생한 희생자에 대한 기억의 보존과 추모, 공동체가 겪은 외상의 치유, 나아가 균열된 사회의 복구 및 건강한 미래사회 건설 등을 목적으로 운영되는 공적의미를 지닌 공간이다. 이런 메모리얼 공간은 전 지구적으로 빈번해지고 있는 자연재해와 사회재난을 극복하고 더 건강한 미래사회 건설을 위한 공간으로 그 필요성이 증가하고 있다. 2014년 세월호 참사는 우리나라에서 사회적 후유증이 컸던 근래 최대의 재난사건이었다. 본 연구는 세월호 참사의 희생자들을 기리기 위해 조성된 4.16기억전시관을 중심으로 메모리얼 참여자들이 경험하는 현상의 본질을 밝혀내고 메모리얼 참여를 통한 외상 치유 및 외상 후 성장의 가능성을 탐색하는 것을 목적으로 한다. 대규모 사건을 목격하고 간접외상을 겪은 공동체가 재능기부와 전시물 기증을 통해 어떻게 자기지각의 변화와 대인관계의 변화, 그리고 인생관의 변화를 이루어냈는지 Tedeschi & Calhoun의 외상 후 성장(posttraumatic growth) 이론을 기반으로 참여자의 경험을 분석하였다. 결과적으로 자기노출(self-disclosure)과 사회적 지지(social support)의 경험이 가능한 상호작용 환경을 기반으로 참여자들이 외상 후 성장 경험을 이루어냈음을 확인하였다.

An Analysis of Semantic Errors in Machine-Translated English Compositions by Korean EFL College Students

백지연 국제문화기술진흥원 2022 International Journal of Advanced Culture Technolo Vol.10 No.3

The purpose of this research is to investigate the types of semantic errors made by MT in translating EFL college students’ original drafts written in Korean into English. Specifically, this study attempts to find out 1) what types of semantic errors are most frequently committed by MT? and 2) how students feel about the quality of the MT-produced output? The findings from this study indicated that MT produced the errors related to accuracy (47%) the most, followed by the errors related to fluency and ambiguity (14.6% respectively). Students were well aware of the errors with accuracy and fluency but had limited ability to check the errors with ambiguity. Based on the findings, this study suggests pedagogical implications which can be implemented in L2 writing classrooms.
