본 연구는 역사적, 사회적 맥락에서 사회적 '장치’로서 개인의 몸이 가지는 의미를 연구하고, 그것이 동시대 시각예술작품에서 비판적으로 드러나는 양상에 대해 살펴보는 것을 목적으로 한다. 이러한 시도를 통해 예술이 사회를 바라보는 방식에 대해 생각해보고자 한다. 미셸 푸코는 생체 권력과 유순한 몸에 대해 논의하면서 근대 이후 개인의 신체는 그 자체가 권력이 작동하는 공간으로 개개의 신체는 훈련받아야 하는 개체로 여겨져 왔다고 언급한다. 다양한 방식으로 미시적인 훈육 과정을 거친 개인의 몸은 개인의 특성에 따라 미세하게 다르지만, 당대의 사회 권력을 담는 개체가 된다. 나아가 몸은 타자에게 권력을 전파하는 장치로 작동하게 된다. 이러한 몸은 기억의 장소로 변모하여 내재된 권력이 그 안에서 더욱 쉽게 영향력을 행사할 수 있도록 한다. 2000년대 이후로 넘어오면서 개인의 몸에 대한 통제는 더욱 미시적이고 은밀하게 이루어지고 있다. 개인의 행동에 대한 관찰은 행동 하나하나를 일련의 패턴으로 변형되어 기록되는 것으로 연결되고, 이는 권력과 사회에 필요한 특정한 행동 양식으로 도출된다. 이렇게 만들어진 행동 패턴은 다시 개인의 편의라는 이름으로 훈육된다. 본 연구에서는 미셸 푸코와 조르주 아감벤의 개인의 몸과 권력 그리고 장치와의 관계에 대한 이론을 바탕으로 알라이다 아스만 등이 언급한 정치·사회적 기억 공간인 몸에 대한 이론적 고찰을 시도한다. 이를 바탕으로 옥인 콜렉티브, 자크 블라스, 줄리앙 프레비유의 작품분석을 시도한다. 가장 은밀한 공간인 개인의 몸을 사회적 맥락 안에서 고찰하고, 관련 예술작품을 분석해보는 것을 통해 개인적이고 일상적인 것을 비판적으로 고려해볼 수 있는 시도를 하였다는 점에서 본 연구는 의의를 가진다. 예술작품이 사회 담론들을 비판적으로 표현하는 것을 분석해보는 것을 통해 예술이 동시대를 바라보는 방식에 대해 생각해 볼 수 있었다. 앞으로 이를 확장하여 논의를 이어갈 수 있는 계기가 될 수 있기를 기대한다. This study explores the meaning of the individual body as a social ‘dispositif’ in the social context to discuss the ways by which its meaning is critically manifested through contemporary visual artworks. While Michel Foucault argues about the ‘bio power’ and ‘docile body’, he theorizes the docile body as a malleable object on which disciplinary force is acted, a node in the complex field in which power is organized and arranged. The body encompassing micro-disciplines in various aspects defines a certain mode of detailed political power and a social dipositif that conveys its power to others. The body upon discipline transforms into storage of memory that facilities the operation of embedded force. The regulation of individuals has been reinforced at a more microscopic and private level after the 2000s. The behavior of individuals is analyzed and collected into data that contains a series of patterns that reveals a certain behavior pattern adequate for the purpose of power and society. Thus, the behavior pattern is disciplined to serve the convenience of individuals. This study considers the theoretical concept of the body constituting a collective memory of policy and society suggested by Aleida Assmann with the background premise of the relation of individual body, power, and dispositif stated by Michel Foucault and Giorgio Agamben. The works by Okin Collective, Zach Blas, and Julien Prévieux are profoundly examined based on the theoretical foundation through which this study focuses on the social meaning infused in the art that embraces a critical outlook on society.

Objectives: It is well-known that post-traumatic stress disorder (PTSD) among firefighters contributes to their job-related stress. However, the relationship between burnout and PTSD in firefighters has rarely been studied. This study therefore explored the association between burnout and its related factors, such as trauma and violence, and PTSD symptoms among firefighters in Korea. Methods: A total of 535 firefighters participated in the Firefighter Research on Enhancement of Safety & Health study at 3 university hospitals from 2016 to 2017. The 535 participants received a baseline health examination, including questionnaires assessing their mental health. A Web-based survey was also conducted to collect data on job-related stress, history of exposure to violence, burnout, and trauma experience. The associations among burnout, its related factors, and PTSD symptoms were investigated using structural equation modeling. Results: Job demands (${\beta}=0.411$, p<0.001) and effort-reward balance (${\beta}=-0.290$, p<0.001) were significantly related to burnout. Burnout (${\beta}=0.237$, p<0.001) and violence (${\beta}=0.123$, p=0.014) were significantly related to PTSD risk. Trauma (${\beta}=0.131$, p=0.001) was significantly related to burnout; however, trauma was not directly associated with PTSD scores (${\beta}=0.085$, p=0.081). Conclusions: Our results show that burnout and psychological, sexual, and physical violence at the hands of clients directly affected participants' PTSD symptoms. Burnout mediated the relationship between trauma experience and PTSD.

Using this signature, we developed a prognostic predictor that can identify patients at high risk of late recurrence, and tested and validated the robustness of the predictor in patients (<I>n = </I>396) who underwent surgery between 1990 and 2011 at four centers (210 recurrences during a median of 3.7 y of follow-up). In multivariate analysis, this signature was the strongest risk factor for late recurrence (hazard ratio, 2.2; 95% confidence interval, 1.3–3.7; <I>p</I> = 0.002). In contrast, our previously developed tumor-derived 65-gene risk score was significantly associated with early recurrence (<I>p</I> = 0.005) but not with late recurrence (<I>p</I> = 0.7). In multivariate analysis, the 65-gene risk score was the strongest risk factor for very early recurrence (<1 y after surgical resection) (hazard ratio, 1.7; 95% confidence interval, 1.1–2.6; <I>p</I> = 0.01). The potential significance of <I>STAT3</I> activation in late recurrence was predicted by gene network analysis and validated later. We also developed and validated 4- and 20-gene predictors from the full 233-gene predictor. The main limitation of the study is that most of the patients in our study were hepatitis B virus–positive.

If hepatocellular cancer (HCC; the most common type of liver cancer) is diagnosed in its early stages, it can be treated by surgically removing part of the liver (resection), by liver transplantation, or by local ablation, which uses an electric current to destroy the cancer cells. Unfortunately, the symptoms of HCC, which include weight loss, tiredness, and jaundice (yellowing of the skin and eyes), are vague and rarely appear until the cancer has spread throughout the liver. Consequently, HCC is rarely diagnosed before the cancer is advanced and untreatable, and has a poor prognosis (likely outcome)—fewer than 5% of patients survive for five or more years after diagnosis. The exact cause of HCC is unclear, but chronic liver (hepatic) injury and inflammation (caused, for example, by infection with hepatitis B virus [HBV] or by alcohol abuse) promote tumor development.</P><P><B>Why Was This Study Done?</B></P><P>Even when it is diagnosed early, HCC has a poor prognosis because it often recurs.

<P>Here we introduce the electromagnetic shielding effectiveness (SE) of reduced graphene oxide (RGO) sheets interleaved between polyetherimide (PEI) films fabricated by electrophoretic deposition (EPD). Incorporating only 0.66 vol % of RGO, the developed PEI/RGO composite films exhibited an electromagnetic interference shielding effectiveness (EMI SE) at 6.37 dB corresponding to ∼50% shielding of incident waves. Excellent flexibility and optical transparency up to 62% of visible light was demonstrated. It was achieved by placing the RGO sheets in the localized area as a thin film (ca. 20 nm in thickness) between the PEI films (ca. 2 μm) to be an interleaved and alternating structure. This unique interleaved structure without any delamination areas was fabricated by a successive application of cathodic and anodic EPD of both RGO and PEI layers. The EPD fabrication process was ensured by an alternating deposition of the quarternized-PEI drops and RGO, each taking positive and negative charges, respectively, in the water medium. We believe that the developed facile fabrication method of RGO interleaved structure with such low volume fraction has great potential to be used as a transparent EMI shielding material.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/aamick/2014/aamick.2014.6.issue-20/am503893v/production/images/medium/am-2014-03893v_0009.gif'></P>

Kim Woojin,Kim A Ram,Ock Minsu,Jeon Young-Jee,Lee Heun,Kim Daehwan,Kim Minjun,Yoo Cheolin 대한직업환경의학회 2023 대한직업환경의학회지 Vol.35 No.1
Background: This study was conducted to identify the success rate for smoking cessation over time after participation in a therapeutic smoking cessation camp, and to identify how participant characteristics, including a supportive workplace environment for smoking cessation (SWESC), affect the success rate for smoking cessation. Methods: In all, 296 participants at smoking cessation camps in Ulsan between 2015 and 2020 were investigated. The success rates of smoking cessation after weeks 4, 6, 12, and 24 at camp were investigated. The participants were grouped as workers with an SWESC, and workers without an SWESC, and variables (age, education, household income, marital status, drinking, exercise, body mass index, morbidity, job, number of counseling sessions, cigarettes smoked per day and smoking initiation age) were investigated. Multiple logistic regression analysis was conducted at each time point. In addition, Cox regression analysis was performed to evaluate the variables affecting the success rate for smoking cessation over time. Results: The smoking cessation success rate of workers with an SWESC at week 24 (90.7%) was higher than that for workers without an SWESC (60.5%). Multiple logistic regression was performed to determine the relationship between each variable and the success rates for smoking cessation at week 6, 12, and 24. SWESC was confirmed as significant (p < 0.05) variables for increased success rate for smoking cessation at all 3 time points. After adjusting for all variables, the Cox proportional hazards survival analysis showed a hazard ratio of 6.17 for SWESC (p < 0.001,; 95% confidence interval: 3.08–12.38). Conclusions: At a professional treatment smoking cessation camp, participants with an SWESC showed a significantly higher success rate for smoking cessation. Supportive workplace environment for workers’ health is expected to be an important factor for smoking cessation projects as well as other health promotion projects at workplace.

In recent years, the utilization of geothermal energy for buildings has increased significantly. Among the existing geothermal energy systems, open loop systems show better efficiency than closed loop systems because of the direct heat exchange with groundwater or surface water. On the other hand, there are a lack of technical and institutional standardized procedures for the design of open loop systems. Therefore, this study proposes an improved design method of an open loop geothermal system using the borehole thermal resistance based on the result of a numerical study using a commercial finite element program (COMSOL Multiphysics). The borehole thermal resistance obtained using the numerical study was 43% lower than that calculated using the existing method. Consequently, the proposed design method can reduce the design length of a ground heat exchanger by approximately 5%. Similar trends of a lower borehole thermal resistance (42%) and shorter design length of the ground heat exchanger (2%) were also observed in the application of the proposed design method to the open loop system in a military facility.
