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.

신자유주의 한국 사회에서 연애하기

박소정(Sojeong Park) 한국여성커뮤니케이션학회 2016 미디어, 젠더 & 문화 Vol.31 No.3

최근 한국 사회에는 연애 욕구를 생성해내는 분위기가 존재하면서도, 한편으로는 연애에 대한 담론이 삼포 세대를 중심으로 한 세대론에 포섭되어 있는 경향이 있다. 본 연구는 연애정상화 담론이나 연애불가능 담론이 지닌 단면성에 대한 문제의식을 바탕으로, 오늘날 신자유주의 한국 사회에서 연애하기의 구체적이고 실천적인 측면을 분석하는 것을 목표로 한다. 그리고 낭만적 사랑 복합체에서 유동적인 합류적 사랑 담론으로 이어지는 서구의 연애 담론에 대한 답습이나 통계상으로 파악되는 친밀성 영역의 변화로는 미처 다 설명되지 못하는, 한국 사회에서의 연애하기의 특수성을 포착하기 위해 한국 로맨틱 코미디 영화의 재현에 주목한다. 최근 한국 로맨틱코미디 영화는 종래의 로맨틱 코미디 문법에서는 조금씩 벗어난 특징들을 보여주고 있으며, 이로부터 신자유주의 한국 사회에서 연애하기가 어떠한 사회경제적 맥락 하에 특수한 양상을 지니고 실천되고 있는가를 읽어낼 수 있다. 오늘날의 연애주체는 신자유주의에 의해 형성된 물적 조건 위에서 상충하고 유동하는 가치체계 속에 놓여있다. 그로 인해 연애관계 속에는 도구적 연애관, 썸과 같은 새로운 관계의 문화, 첫사랑에 대하 노스탤지어, 남성성의 변화 등 다양한 면모가 존재한다. 이로부터 삼포세대나 연애불가능 세대라는 비관적 호명을 벗어나 젊은 세대가 친밀성 영역에서 보여주는 감수성과 실천에 대한 구체적 논의를 모색해보고자 한다. This study analyzes the aspects and meanings of romantic relationship in neoliberal Korean society. In South Korea, ‘love’ carries a distinguished meaning, as Korean society’s particular context should be considered. The term ‘N-po generation’ is a striking example that reflects the structural poverty of contemporary Korea’s young generation, which leads to the formation of the discourse on the impossibility of love. On the other hand, society encourages the youth to engage in romantic relationship as the media actively deals with romance and sexual issues. This paradox between the impossibility of love and the normalization of love in today’s Korean youth culture is the starting point of this study. To grasp the particularity of romantic relationship in contemporary Korean society, this study analyzes the representation of romantic relationship in Korean romantic comedy movies since 2008, which show different characteristics from conventional romantic comedy movies. Through text analysis and discourse analysis, we can find out that the recent socioeconomic structure situates romantic relationship in the fluctuating and contradictory values, resulting in new practices, norms, and sensitivities in romantic relationship. The subjectivity of the individual in romantic relationship implies a silver lining against all the superficial and pessimistic discourses that surround the contemporary Korean society.

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.
