        모성의 의료화 : 맘카페의 모유수유 담론을 중심으로

        왕혜숙(Wang, Hye Suk),송민이(Song, Minyi) 동양사회사상학회 2021 사회사상과 문화 Vol.24 No.3

        모성에 대한 기존 연구들은 주로 양육과 가사노동의 합리적 통제를 통해 모성이 과학화되고 있음을 주장한다. 이 논문은 맘카페의 모유수유와 관련된 게시글들에 대한 분석을 통해, 모성의 과학화에 대한 기존 논의를 확장하여 모성의 의료화가 심화되어 나가고 있음을 확인해본다. 기존 논의에서 과학화의 대상은 주로 육아나 가사노동에 한정되어 있던 것에 반해, 논문의 분석 결과는 의료화의 대상이 어머니의 몸 자체로 확장되고 있음을 보여준다. 나아가, 분석 결과를 토대로 이 논문은 모성의 의료화 현상을 이끄는 주체와 방식에 대한 질문을 던진다. 기존 연구들에서 모성의 과학화를 주도하는 주체는 근대국가(인구통치)의 생체권력과 결합한 의료전문가들로 지목된다. 여기서 어머니들은 거시적인 주체들의 논리를 실천하는 역할만을 담당하는 수동적 존재이다. 이에 반해 분석 결과는 어머니들이 의료전문가들의 의료지식과 전문용어에 절대적으로 의존하기보다는 자신들만의 경험과 지식에 더욱 의존하는 영향을 보여준다. 특히 이 논문은 어머니들이 자신들만의 주관적인 경험과 지식을 표현하고 공유하기 위한 독자적인 용어들이 생산되는 장으로서 온라인 커뮤니티의 역할에 주목한다. Existing Literature on motherhood claims the advance of scientific motherhood mainly based on the increasing control on child-care and house-keeping. To extend this claim, this article examines how the motherhood is scientificated or medicalized. It identifies key terms and topics in posts on an online forum, called “Mom cafe.” Based on the analysis on 4,947 online posts that mention related to “baby feeding,” this article highlights the two finding regarding the medicalized motherhood. First, the area of medicalization is extend beyond child and house-keeping to mother’s body. The earlier process of scientific and rational control on babies’ bodies continue. At the same time, mothers actively find problems in their breasts and try to correct them in order to feed their babies properly. It shows that mothers conceive their bodies as medical or bio-resourse to be fully utilized. Secondly, the process of medicalization is geared not by medical professionals but by mothers. Moreover, mothers play a leading role in medicalization and scientification by constructing their own languages and terms to describe and deliver their experiences and subjective knowledge. It critically examines the conventional hypothesis on the hierarchical relationship between medical and academic professionals and mothers as patient in the medical sociology.

        Effect of freezing on electrical properties and quality of thawed chicken breast meat

        Ran Wei,Peng Wang,Minyi Han,Tianhao Chen,Xinglian Xu,Guanghong Zhou 아세아·태평양축산학회 2017 Animal Bioscience Vol.30 No.4

        Objective: The objective of this research was to study the electrical properties and quality of frozen-thawed chicken breast meat and to investigate the relationship between these parameters at different times of frozen storage. Methods: Thawed samples of chicken breast muscles were evaluated after being kept in frozen storage at –18°C for different periods of time (1, 2, 3, 4, 5, 6, 7, and 8 months). Results: The results showed that water-holding capacity (WHC) and protein solubility decreased while thiobarbituric acid-reactive substances content increased with increasing storage time. The impedance module of samples decreased during 8-month frozen storage. Pearson correlation coefficients showed that the impedance change ratio (Q value) was significantly (p<0.05) related to pH, color, WHC, lipid oxidation and protein solubility, indicating a good relationship between the electrical properties and qualities of frozen-thawed chicken breast meat. Conclusion: Impedance measurement has a potential to assess the quality of frozen chicken meat combining with quality indices.

        A Parallel-Structure-Based Sliding Mode Control for Trajectory Tracking of a Quadrotor UAV

        Yu Hei-Pei,Wang Minyi,Yang Jiaqianhao,Xiong Jing-Jing 대한전기학회 2023 Journal of Electrical Engineering & Technology Vol.18 No.5

        In this paper, aiming at the problem of incomplete yaw angle working range in a class of sliding mode control for quadrotor unmanned aerial vehicle (UAV), a parallel-structure-based sliding mode control (PSMC) method is proposed. Firstly, the dynamic model of the quadrotor UAV is considered to be composed of fully actuated subsystem and underactuated subsystem. For the fully actuated subsystem, the regular sliding mode manifold is used to design the controller. For the underactuated subsystem, the coordinate transformation of the error is taken into account in the sliding mode manifold. The coefficients of the sliding mode manifold can be obtained by the Hurwitz stability analysis. In addition, the stabilities of two subsystems are demonstrated by Lyapunov theory. Finally, comparative simulation results show that the PSMC not only improve the working range of yaw angle, but also illustrate the effectiveness of the proposed control method.

        Analysis of Tau Protein Expression in Predicting Pathological Complete Response to Neoadjuvant Chemotherapy in Different Molecular Subtypes of Breast Cancer

        Chuqian Lei,Ciqiu Yang,Bin Xia,Fei Ji,Yi Zhang,Hongfei Gao,Qianqian Xiong,Yufeng Lin,Xiaosheng Zhuang,Liulu Zhang,Teng Zhu,Minyi Cheng,Mei Yang,Kun Wang 한국유방암학회 2020 Journal of breast cancer Vol.23 No.1

        Purpose: Tau is a microtubule-associated protein that can be found in both normal and abnormal breast cells. Whether the expression of Tau protein can predict the response to neoadjuvant chemotherapy (NACT) is still unclear. In this study, we assessed the role of Tau protein expression in predicting a pathological complete response (pCR) to NACT for different subtypes of breast cancer. Methods: Four hundred and sixty-eight eligible patients were retrospectively recruited in our study. The relationship between clinicopathologic factors, including Tau protein expression, and pCR in different subtypes was evaluated using logistic regression analysis. Correlation between Tau and disease-free survival (DFS) and overall survival (OS) was performed using Kaplan–Meier analysis. Results: The expression of Tau protein was negatively correlated with pCR, especially in triple-negative breast cancer (TNBC). No significant difference was observed in the luminal human epidermal growth factor receptor-2 (HER2)-negative subtype and HER2-positive subtype. Patients with pCR were associated with better DFS and OS (p < 0.05). However, Tau protein expression had no association with either DFS or OS (p > 0.05). Conclusion: Tau protein expression can predict pCR before NACT in TNBC, but there was no correlation between Tau expression and DFS or OS.
