Objectives: This study investigated the 24-hour ambulatory blood pressure monitoring (ABPM) and Holter parameters for evaluating their prognostic significance of cardiovascular events including stroke in population without atrial fibrillation (AF). Methods: Among 3,199 patients that underwent ABPM, 335 who also underwent Holter recordings were selected in a tertiary hospital. Seventeen patients who had been documented with AF on Holter monitoring or diagnosed with AF were excluded, and finally 318 patients were analyzed. The association between cardiovascular events and ABPM/Holter parameters was analyzed by a logistic regression model, and the risk factors were estimated by a Cox hazard model. Age, sex, and histories of cardiovascular disease were adjusted by a multivariable analysis, and the cut-off values were suggested by a Kaplan-Meyer analysis. Results: During the total follow-up (28.5±1.7 months), 13 (4.1%) stroke, 6 (1.9%) heart failure, and 12 (3.8%) acute coronary syndrome incidences were observed. In the univariate analysis of the ABPM parameters, an increment in the night systolic BP (hazard ratio=1.034, P=0.020) and night diastolic BP (hazard ratio=1.063, P=0.031) significantly elevated the risk of a stroke occurrence. According to the Kaplan-Meyer analysis, there was a significant difference in the stroke incidence between the groups divided by a cut-off value of the night systolic BP of 120 mmHg (P=0.014) and night diastolic BP of 75 mmHg (P=0.023). Conclusion: In a population without AF, the nocturnal BP was a significant predictor of a stroke incidence. At this point, the cut-off value of mean 120/75 mmHg in 24 ABPM was advisable.

Microorganisms involved in food fermentation not only improve the aroma and taste of the food, but also enhance its preservation. Thus, they are added as starter cultures to boost the final product quality of commercial fermented foods. Although these microorganisms originate from fermented foods and have a long history of consumption, the European Union recently applied the concept of Qualified presumption of Safety (QPS), which is a safety evaluation system for microorganisms used in food or feed in Europe. The QPS system is a species-level safety system and shares results with the European Novel Food System, a strain-level safety evaluation system. In the United States, microorganisms added to fermented foods are considered as food additives or Generally Recognized as Safe substance. In Korea, food microbe lists are presented at the species level. Moreover, the nation has established a strain-oriented evaluation system that applies temporary safety evaluation methods for food raw materials as well as new raw materials. However, when it comes to microorganisms isolated from traditional fermented foods and other fermented food products, there is no definition of the term “species,” and there is a lack of an evaluation system at the species level. Therefore, such an evaluation system for microbial species used in Korean fermented foods is necessary.

박소정(Sojeong Park),김지윤(Jiyoon Kim),장시연(Siyeon Jang),채태준(Taejun Chae) 한국여성커뮤니케이션학회 2021 미디어, 젠더 & 문화 Vol.36 No.1

본 연구는 최근 형성되고 있는 국내의 복잡한 다문화주의의 지형과 새로운 인종주의적 현상들을 배경으로 가나 출신의 방송 스타인 샘 오취리를 통해 한국 다문화주의의 발전과 한계를 짚어보는 것을 목표로 한다. 오취리는 국내 여러 방송 프로그램에 출연하며 스타덤을 형성했지만 블랙페이스 문제와 관련된 이른바 ‘관짝소년단 논란’을 겪으면서 활동을 중단한 인물로서, 본 연구는 그를 한국 미디어와 사회의 다문화성을 진단하는 하나의 담론적 텍스트로 바라본다. 스타 이미지란 스타 개인이 보유한 특정 성질만으로 형성되는 것이 아니라 사회 및 대중과의 관계 속에서 형성되는 것이라고 할 때, 인종적 성격과 스타로서의 성격의 접합을 통해 만들어진 오취리의 스타 이미지는 한국 사회의 다문화주의와 인종주의의 한 단면을 드러낸다. 오취리의 스타 이미지를 구성하는 홍보, 평판, 역할, 비평 영역의 미디어 텍스트들을 관찰한 결과, 오취리는 유사 한국인으로서, 한국적 정서를 매개하는 재담꾼으로서, 한국의 다문화성을 증명해줄 흑인의 대표자로서의 이미지를 통해 한국 미디어 및 사회 안에서 긍정적으로 포용될 수 있었음을 발견할 수 있었다. 그러나 관짝소년단 논란은 대중들이 이러한 이미지를 벗어난 오취리를 발견하게 된 계기였고, 오취리의 이미지는 흑인에게 부여되어 온 종래의 부정적 관념들로 대체 및 재구성되었다. 오취리의 스타 이미지가 구축 및 해체되는 일련의 과정을 통해 본 연구는 한국 다문화주의에 내재한 모순 및 한계를 다양성, 대표성, 진정성의 차원에서 개념화하여 논의한다. 이를 통해 한국의 다문화주의가 언제든 타자성을 복원할 수 있는 불안정한 담론에서 단단한 토대를 지닌 일상의 감수성으로 성장해야 함을 주장한다. Facing the current state of multiculturalism and the emerging racial issues, this study aims to examine the development and limitations of multiculturalism through the case of Sam Okyere, a Ghanaian TV star in South Korea. Appearing on various Korean TV programs, Okyere has formed stardom but discontinued his activities due to the recent controversy on blackface. We interpret him as a discursive text through which we can diagnose the multiculturality of Korean media and society. As star image is not merely formed by the specific characteristics of an individual star, but in a relation to society and the public, Okyre’s star image articulated by his racial traits and star personality reveals the current stage of multiculturalism and racism in Korean society. This study looks into various media texts that arguably function as promotion, publicity, role, and criticism in making star image. The findings show that Okyere was embraced in the Korean media and society through the star image as a ‘quasi-Korean’, ‘raconteur’ who successfully understood and mediated Korean humour, and ‘representative of black people’ that proved the advancement of multiculturalism in Korea. However, the controversy of blackface deviated his star image, and his image was thereby replaced and reconfigurated with the conventional negative stereotypes on black people. Exploring how Okyere’s star image is constructed and dismantled, this study discusses the contradictions and limitations embedded in Korean multiculturalismty. Finally, this study argues for a higher cultural sensitivity to multiculturalism and anti-racism.

K-뷰티산업의 피부색주의

박소정(Sojeong Park) 한국언론학회 2020 한국언론학보 Vol.64 No.6

While K-Beauty is globally recognized as a burgeoning industry, this study explores and analyzes the colorism of the K-Beauty industry. Colorism, or discrimination based on skin colors, can be found in the discourse of hierarchies formed by the culmination of idealized skin called ‘mibaek’ in Korean society. And K-Beauty industry which is the Korean media-beauty complex mediates this discourse to overseas audiences. As the imagery of impeccably fair skin of Korean stars is epitomized as a new beauty model in East Asia, K-Beauty produces new norms and hierarchies that require critical exploration. What cultural significance does K-beauty have in the global media-beauty scene? And what hegemonic power does it exert? In order to answer these questions, this study explored various images and texts on K-beauty online and conducted focus group interviews in Thailand and Vietnam. The findings reveal that Korea is being perceived as a ‘country of white skin’ by overseas K-Beauty consumers. In particular, K-beauty provides Southeast Asian people with an attainable beauty model or relatable ideal, replacing Westernized beauty norms. However, on the other hand, colorism is produced in the process of K-beauty being circulated as a transnational product, and this study aims to provide a critical perspective on this. K-Beauty reveals its imperial power through the exclusivity of Korean stars’ bodies, the formation of a hierarchy between Northeast Asia and Southeast Asia, and its barrier to racially otherized bodies. First of all, K-pop idols who are the main mediators of K-beauty mostly conform to a specific visuality. This implies the confined Koreanness of K-beauty, which is not free from colorism as it excludes other racial visualities. Second, several quasi-K-beauty products in Southeast Asian countries regards the Northeastern look as a beauty model, highlighting a lighter complexion. And this produces and reproduces the hierarchy between Northeast Asia and Southeast Asia. Lastly, this study pays attention to black beauty YouTubers who have tried K-beauty make-up. Their content and perceptions of some audiences reveal that the diversity and inclusivity of the K-beauty industry is highly limited or nothing more than a marketing rhetoric. As such, in the realm of K-Beauty, where the ‘K’ strongly signifies a certain power related to nationalism, it tries to secure a territory exclusive to a specific skin color. Based on all these findings, this study argues for the necessity of cultivating sensitivity to the matter of race, ethnicity, and skin color that have long been overlooked in Korean society, and suggests further inquiries for Korean media studies.

PMN-PZT/Ni 자기-전기 복합체에서 단결정 압전 모드에 따른 자기장 감도 특성

박소정 ( Sojeong Park ),( Mahesh Peddigari ),류정호 ( Jungho Ryu ) 한국센서학회 2020 센서학회지 Vol.29 No.1

Magnetoelectric (ME) composites were designed using the PMN-PZT single crystal and Ni foils; the properties and magnetic-field sensitivities of ME composites with different piezoelectric vibration modes (i.e., 31, 32, and 36 modes that depend on the crystal orientation of the single crystal) were compared. In the off-resonance condition, the ME coupling properties of the ME composites with the 32 and 36 piezoelectric vibration modes were better than those of the ME composites with the 31 piezoelectric vibration mode. However, in the resonance condition, the ME coupling properties of the ME composites were almost similar, irrespective of the piezoelectric vibration mode. Additionally, in the off-resonance condition (at 1 kHz), the magnetic-field sensitivity of the ME composites with the 36 piezoelectric vibration mode was up to 2 nT and those of the ME composites with the 31 and 32 piezoelectric vibration modes were up to 5 nT. These magnetic-field sensitivities are similar to those offered by conventional high-sensitivity magnetic-field sensors; the potential of the proposed sensor to replace costly and bulky high-sensitivity magnetic field sensors is significant.

‘아재’라는 호명의 독

박소정(Sojeong Park) 한국여성커뮤니케이션학회 2017 미디어, 젠더 & 문화 Vol.32 No.3

본 연구는 최근 대중문화 속에서 ‘아재’ 코드가 헤게모니적 남성성을 구축 및 회복하는 과정을 살펴본다. ‘아저씨’의 방언이라는 사전적 의미를 지닌 아재는 최근 2∼3년 사이 온라인상에서 특정한 정체성과 코드를 포괄하는 말로 전유 및 확산되더니, 이제는 지상파 TV 프로그램에서까지도 공공연히 사용하는 유행어가 되었다. 그 과정에서 아재가 의미하는 바를 둘러싼 호명의 정치가 이루어졌고, 결과적으로 아재는 단순히 인구통계학적인 차원에서의 중년 남성(man)을 일컫는 것이 아니라, 여러 가지 의미가 뒤섞여 인식되는 특정한 형태의 남성성(masculinity)을 지칭하게 되었다. 그 남성성을 본 연구에서는 세대와 젠더의 교차점에서 고찰되어야 할 교차적 정체성으로 주목한다. 헤게모니적 남성성이 위기를 맞이하고 저항적 청년문화의 공백이 문제시되는 가운데, 과거의 남성 청년이던 아재는 헤게모니적 남성성을 소환해낸다. 더욱이 문제가 되는 것은 아재가 소환해낸 구시대의 남성성에 청년들이 의식적으로든 부지불식간에든 동의하는 움직임이 나타나고 있다는 점이다. 아재라는 호명은 오래된 헤게모니적 남성성을 친근하고 안전한 방식으로, 그리고 새로운 코드인 마냥 향유하게 만듦으로써 한국의 남성 동성사회성과 젠더 위계를 공고화한다. 그 과정에서 나타나는 젠더역학과 윤리적 결함에 대해 해석하고 비판하는 것이 본 연구의 궁극적 목적이다. This study examines how ‘Ajae’ code of popular culture constructs or restores hegemonic masculinity. ‘Ajae’ originally means ‘middle-aged man’, but it has been appropriated by young people of online subculture with the intention of satirizing middle-aged men. As it became a fad word, mainstream media such as terrestrial TV programs have re-appropriated the term to include different aspects of masculinity. As a result, Ajae has become a multidimensional term that requires explanation. Ajae is not just a middle aged ‘man’, but a ‘masculinity’ which should be explored at the intersection of gender discourse and generation discourse. While hegemonic masculinity is at stake and the absence of resistant youth culture is questioned, Ajae, who was a male youth in the past, summons hegemonic masculinity. What is more problematic is that there is a movement in which young people either consciously or unknowingly agree with that masculinity. The interpellation of Ajae makes old hegemonic masculinity spread as a new identity code in a friendly and safe way, thereby consolidating the homosociality of Korean men and gender hierarchy between men and women. The ultimate goal of this study is to examine and criticize gender dynamics and ethical flaws in this discursive process.

일본 내 글로벌 SVOD 서비스를 통한 한국 드라마 수용

박소정(Sojeong Park),장인희(Inhee Jang),홍석경(Seok-Kyeong Hong) 한국언론학회 2021 한국언론학보 Vol.65 No.3

The current popularity of Korean dramas in Japan—including Crash Landing on You (tvN, 2020), which ranked first place in the 2020 rankings of Netflix Japan—is suggesting the emergence of a 4th Hallyu in Japan, implying a change in the reception of Korean dramas among the Japanese audience. This study seeks to understand the specific aspects of this change by focusing on the experiences of the Japanese audience who watch Korean dramas on Netflix. What is new about the current Hallyu phenomenon in Japan, where global SVOD platforms mediate Korean dramas? Furthermore, what significance can we interpret from this? To answer these questions, this study conducted in-depth interviews with 8 Japanese viewers of different ages and gender and observed Japanese news articles on the 4th Hallyu or Crash Landing on You. Our findings reveal that Netflix plays a significant role in attracting Japanese viewers to Korean dramas as it provides the latest Korean dramas in real-time and its recommendation system prompts the audience to explore more Korean dramas. Secondly, another remarkable reason that the Japanese audience chooses Korean dramas among other various global content is the growing quality of Korean dramas. With the qualitative turn in the 2010s, Korean dramas have been gradually growing in scale and in quality through changes in production systems and with the production of Korean Netflix Originals. These changes have shifted the preconceived notion that Japanese people have had of Korean dramas, that they mostly show old-fashioned melodramatic stories or light romantic comedies aimed primarily at the female audience. All of the interviewees had a high opinion of the current Korean dramas, saying that they are a good blend of sophisticated stories and spectacular scenes. Therefore, among Japanese viewers, Korean dramas are regarded as an outstanding form of global content rather than the content that Japanese people consume based on nostalgia or cultural proximity. Lastly, this study discusses the political implications of the reception of Korean dramas by the Japanese audience. While political relations between Korea and Japan have not met a positive moment for the last several years, the reception of Korean dramas seems to promote cultural exchanges and mutual awareness in terms of cultural politics. In particular, it is noteworthy that the narratives and characters of recent Korean dramas provide progressive milestones for feminism and gender discourse in Japanese society. In conclusion, Korean dramas are shifting to a more high-quality global content that represents the future of drama production in Japan, beyond the nostalgic or romcom-style content consumed based on cultural proximity.
