The Queen of the Air, John Ruskin-s highly elliptical publication of 1869, elaborates a complex mythology as a way of responding to the prevalence of scientific thinking, widespread environmental degradation, the pernicious effects of political economy, and mechanistic labor. Benjamin-s desire to rescue human experience from prevailing scientific conceptions is reminiscent of Ruskin-s fear that the peculiar power that shapes the unities of the natural world is simultaneously being "beaten down by the philosophers into a metal or evolved by them into a gas" and obscured by the dreams and theories of philosophers and theologians. As a critic remarks, in Benjamin-s-and, we would add, Ruskin-s-view, "what the modern era lacked was a basis for continuity which would prevent experience from disintegrating into a desultory and meaningless series of events." Despite its frenetic hyper-associativity, then, The Queen of the Air contains a key element that Benjamin believes is necessary for "redemption": the desire for a new form of consciousness that recognizes links to the past and thus to the longings and dreams of our forebears. Thus, although Ruskin most immediately influences Proust, who in turn influences Benjamin, Benjamin-s thought is far more Ruskinian than critics have heretofore observed. Just as Benjamin helps us make sense of the ways in which The Queen of the Air is caught in the grip of the shocking associativity of modern life, so Ruskin assists us in discerning similar impulses in Benjamin-s attraction to a form of archaic consciousness that can, by altering the modern form of perception, reenchant the present.

Computed tomography (CT) is being utilized in orthopaedics and related research to estimate bone strength. These applications benefit from calibration of Hounsfield units to mineral density typical of long bone, up to $1750mg/cm^3$. This study describes a method for establishing repeatable calibration of Hounsfield units to density, and determines the effects of imaging medium on calibration accuracy. Four hydroxyapatite standards were imaged in air on 7 occasions over 19 weeks using a helical multi-slice CT scanner. Each standard was scanned 5 times in different media: porcine soft tissue, water, and air. Calibrated densities were highly repeatable (CV<3.5%). No difference in density was observed between water and soft tissue conditions (p>0.08). This work provides a model for determining repeatable scanner-specific density calibration, demonstrates that the linear relationship between Hounsfield units and density extends to values typical of cortical bone, and supports the practice of imaging calibration standards in an environment similar to that of the target bone.

This study investigates the factors that affect China's air pollution using city-level panel data and spatial econometric models. We address three air pollutants ($PM_{10}$, $SO_2$, and $NO_2$) present in 30 cities in China between 2004-2012 using global OLS and spatial models. To develop the spatial econometric analysis, we create a spatial weights matrix to define spatial patterns based on two neighborhood criteria - the queen contiguity and k nearest neighbors. The results show that the estimated coefficients are relatively consistent across different spatial weight criteria. The OLS models indicate that the effect of green spaces is statistically significant in decreasing the concentrations of all air pollutants. In the $PM_{10}$ and $SO_2$ analyses, the OLS models find that the number of buses and population density are also positively related to a reduction in the concentration of air pollutants. In addition, an increase in the temperature and the presence of secondary industries increase $SO_2$ and $NO_2$ concentrations, respectively. All spatial models capture a positive and significant effect of green spaces on reducing the concentration of each air pollutant. Our results suggest that green spaces in cities should receive priority consideration in local planning aimed at sustainable development. Furthermore, policymakers need to be able to discern the differences among pollutants when establishing environmental policies.

The time-dependent behavior of unsteady condensation of moist air through the Ludwieg tube is investigated by using a computational fluid dynamics (CFD) work. The two-dimensional, compressible, Navier-Stokes equations, fully coupled with the condensate droplet growth equations, are numerically solved by a third-order MUSCL type TVD finite-difference scheme, with a second-order fractional time step. Baldwin-Lomax turbulence model is employed to close the governing equations. The predicted results are compared with the previous experiments using the Ludwieg tube with a diaphragm downstream. The present computations represent the experimental flows well. The time-dependent unsteady condensation characteristics are discussed based upon the present predicted results. The results obtained clearly show that for an initial relative humidity below 30% there is no periodic oscillation of the condensation shock wave, but for an initial relative humidity over 40% the periodic excursions of the condensation shock occurs in the Ludwieg tube, and the frequency increases with the initial relative humidity. It is also found that total pressure loss due to unsteady condensation in the Ludwieg tube should not be ignored even for a very low initial relative humidity and it results from the periodic excursions of the condensation shock wave.

Objective: To investigate the association between functional tumor burden of peritoneal carcinomatosis (PC) derived from diffusion-weighted imaging (DWI) and overall survival in patients with advanced ovarian carcinoma (OC). Materials and Methods: This prospective study was approved by the local research ethics committee, and informed consent was obtained. Fifty patients (mean age ± standard deviation, 57 ± 12 years) with stage III-IV OC scheduled for primary or interval debulking surgery (IDS) were recruited between June 2016 and December 2021. DWI (b values: 0, 400, and 800 s/mm²) was acquired with a 16-channel phased-array torso coil. The functional PC burden on DWI was derived based on K-means clustering to discard fat, air, and normal tissue. A score similar to the surgical peritoneal cancer index was assigned to each abdominopelvic region, with additional scores assigned to the involvement of critical sites, denoted as the functional peritoneal cancer index (fPCI). The apparent diffusion coefficient (ADC) of the largest lesion was calculated. Patients were dichotomized by immediate surgical outcome into high- and low-risk groups (with and without residual disease, respectively) with subsequent survival analysis using the Kaplan-Meier curve and log-rank test. Multivariable Cox proportional hazards regression was used to evaluate the association between DWI-derived results and overall survival. Results: Fifteen (30.0%) patients underwent primary debulking surgery, and 35 (70.0%) patients received neoadjuvant chemotherapy followed by IDS. Complete tumor debulking was achieved in 32 patients. Patients with residual disease after debulking surgery had reduced overall survival (p = 0.043). The fPCI/ADC was negatively associated with overall survival when accounted for clinicopathological information with a hazard ratio of 1.254 for high fPCI/ADC (95% confidence interval, 1.007-1.560; p = 0.043). Conclusion: A high DWI-derived functional tumor burden was associated with decreased overall survival in patients with advanced OC.

Purpose: The presence of alcoholic stool in biliary atresia (BA) patients is the basis of a stool color card (SCC), a screening tool that has led to more patients receiving Kasai portoenterostomy earlier. This study aimed to evaluate the color image processing of stool images captured using smartphones. We propose that measuring digital color parameters is a more objective method for identifying BA stools and may improve the sensitivity of BA screening. Methods: A prospective study was conducted in five hospitals in Thailand between October 1, 2020, and December 31, 2021. Stools from infants presenting with jaundice, acholic stool, or dark-colored urine were photographed. Digital image color analysis was performed, and software was developed based on the color on the original SCC. Sensitivity and specificity for predicting BA stools were compared between the SCC and the software. Results: Of 33 infants eligible for data collection, 19 were diagnosed with BA. Saturation and blue were two potential digital color parameters used to differentiate BA stools. The receiver operating characteristic curve was used to determine the optimum cutoff point of both values, and when saturation ≤56 or blue ≥61 was set as a threshold for detecting BA stool, high accuracy was achieved at 81.8% and 78.8%, respectively. Conclusion: Digital image processing is a promising technology. With appropriate cutoff values of saturation in hue, saturation, value and blue in red, green, blue color models, BA stools can be identified, and equivocal-colored stools of non-BA patients can be differentiated with acceptable accuracy in infants presenting with jaundice.

본고는 일본 현대연극이 가타리모노 셋교부시를 수용하여 어떻게 현대화했는가에 주목하여 작품을 분석하였다. 아울러 이를 통하여 '셋교부시에 의한 미세모노(見せ物)오페라' 장르로 탄생하는 과정을 밝히고자 하였다. 이와 관련해서는 중세의 스토리텔링 셋교부시를 현대적 '미세모노 오페라'로 재탄생시켰다는 점에서, 데라야마가 언그라 1세대들과 확연히 다른 점에 대해 논했던 종래의 평가들과는 또 다른 시각을 제시하고자 한다. 60년대 일본 언그라운동 1세대 데라야마 슈지(寺山修司)의 <신토쿠마루(身毒丸)>(1978년)는 서사적 이야기에 가락을 붙여 음송하는 가타리모노(語り物) 셋교부시(說經節) <신토쿠마루(俊德丸)>를 소재로 한 작품으로서, 동아시아 스토리텔링의 현대적 유산이라고 할 수 있다. 셋교 <신토쿠마루>는 계모의 저주로 나병에 걸린 신토쿠마루가 텐노지(天王寺)에서 약혼자 오토히메(乙姬)라는 여성의 헌신적인 사랑과 관음(?音)의 영력(?力)에 의해 구원되는 이야기이다. 데라야마 슈지는 셋교부시의 서사적 형식에 J.A.시저(シ?ザ?본명 寺原孝明)의 주술적인 락(rock)음악을 결합시키고 부제를 '셋교부시에 의한 미세모노 오페라(說敎節による見世物オペラ)'라고 하였다. 근원소재인 모자신 신앙(母子神信仰)의 원리로 보이는 '모도리(もどり; 회귀)' 본능의 중세적 종교 세계를 데라야마 슈지는 모자상간의 세계로 변화시킨다. 그리고 셋교부시에서 나타나는 보편적인 복수장면은 신토쿠마루가 계모인 나데시코(撫子)의 복장과 가면을 쓴 드래그 퀸(drag queen: 여장)의 모습으로 이복동생 센사쿠(せんさく)를 근친상간하는 것으로 복수한다. 이 작품은 셋교부시의 전형적인 인과 구조를 따르고 있고, 작품 전반에 개입하여 전체적 서사를 진행시키는 이야기꾼(語り手, 카타리테)과 야나기타 구니오(柳田國男)박사의 등장은 서사 장치인 자기소개 기법과 코러스의 현대적 활용을 보여준다. 특히 코러스 가사에서 데라야마 슈지의 불행한 어린 시절의 기억, 즉 아버지의 부재, 아오모리현(?森?)의 대공습 경험이 자동기술법처럼 묘사되어 내용을 심층화하고 있다. 이후 니나가와 유키오(?川幸雄)의 연출 버전은 초연 때부터의 공동 극작가였던 기시다 리오(岸田理生)가 데라야마의 사후 17년을 경과해 다시 쓴 개정판으로 데라야마 슈지의 원작 <신토쿠마루>를 널리 알렸다. 그러나 그의 연출 버전에서는 데라야마가 이 작품에 붙인 부제의 요소가 전부 삭제됨으로써 극단 연극실험실 '덴조사지키(天井?敷)'가 시도한 다양한 실험연극의 줄기와 본질로부터 벗어나 있다. <신토쿠 마루>는 현대연극의 서사구조를 갖고 있지만 각 단락이 독립적인 이야기를 구성하면서도 서로 유기적인 결합이 가능하도록 한 구조를 갖고 있다.
