"Behind a Mask" (1866) marks the new direction of Louisa May Alcott's artistic and personal life. Her European trip solidified her identity as a mature woman, most importantly as a mature American woman, one whose independence from Victorian stereotypes would, from now on, make her fortune and fame. Her sensational stories, especially "Behind a Mask," would tell truths that readers recognized but had rarely seen written. These truths would free them, and the author herself, to explore their talents as individuals. Henceforth, Alcott would embody the successful American artistic entrepreneur as one who shed the European domination of false titles and inherited wealth. These motifs of the transnational connection pervade the story, in the form of images and likenesses. Just as Alcott would soon, in two years, reach astonishing financial success with the publication of Little Women, her meteoric ascent parallels America's rise to power in the world's economy, which came about with almost alarming speed after the conclusion of the American Civil War.

Eugene O'Neill portrays Puritan values of the Mannon family inherited from their family past. Since Puritan values of the Mannons suppress the normal way of life and love, they retain only rigidity, without the charity which is the core element of the teaching of Christianity. With Puritan repression and its dissociation from the vital spring of life, the Puritan Mannons live in a world drained of life and in a world of hypocrisy between outer beauty and inner ugliness. Ironically, they think more of death itself, neglecting to feel the vitality of life. Working as a fate, Puritan values of the Mannon as 'Force Behind' in O'Neill's own term are the cause of suffering and destruction of the Mannons throughout the whole play. The mask-like house and faces are effectively used as a dramatic technique to express the distorted Puritan values.

Tension mask assembly is positioned right behind the glass-made front panels of CRT type display devices. The frame-supported thin metal sheet contains numerous slits, through which electron beams are focused to enhance definition. Pretension is imposed on the masks, especially for enlarged flat screens, in order to avoid vibration due to acoustic or mechanical impact. High temperature assembly process subsequent to pretensioning, however, degenerates the creep resistance of common mask materials, and if tensile stress is high enough, tension on the mask may be loosened substantially due to creep deformation. In this study, the assembly is modeled as a combined structure of beams and wire array, and a numerical simulation is attempted for pretensioning followed by high temperature process. According to a model study, small amount of creep strain is likely to be generated, but its adverse influence is not negligible. Some structural modification measures to reduce the creep-induced tension loosening are proposed and evaluated. Also, optimal configuration of frame structure is sought for, which maintains high tension of masks and minimizes the possible creep of frame simultaneously.

Tension mask is a part of CRT type devices, which is installed right behind glass-made front panel. Numerous slits on the thin metal sheet enable the electron beams emitted from posterior gun to be focused, resulting in enhanced definition. Flattened and enlarged displays necessitate the imposition of pretension on the masks, in order to improve the robustness of display quality against vibration or impact. High temperature assembly process subsequent to pretensioning, however, degenerates creep resistance of mask material, and common mask may become susceptible to undesirable elongation due to creep. Once tensile stress becomes high enough to induce creep deformation, pretension is substantially loosened. In this study, tension mask assembly is modeled as a combined structure of beams and wire array, and a numerical simulation is attempted for pretensioning followed by high temperature process. Based on a model study, creep occurrence is found to be probable and its adverse influence is quantified. As fur maintaining high tensile force, simply increasing pretension does not seem to be helpful. Instead, the structure of frame needs to be modified somehow, or material for mask needs to be selected properly.

This paper gives a feminist reading of Suzanne Alexander in The Alexander Plays by focusing on her performances as active reconstitutions of history and memory. A compilation of four of Adrienne Kennedy's more recent plays, The Alexander Plays revolves around a central protagonist who, behind windows and within the closed spaces of the home, waits for her missing husband to return home. Yet, the plot of the waiting wife seems to mask the hidden and more dangerous desires for political transgressions of the play. By analyzing Suzanne's interaction with various literary and historical figures, memories and events, this paper argues that her seeming approval of domesticity, femininity and intimacy serves as a cover for her more political altercations with history, race and gender.

In this paper, we demonstrate a self-imaging technique that can visualize longitudinal interference patterns behind periodically-structured objects, which is often referred to as Talbot carpet. Talbot carpet is of great interest due to ever-decreasing scale of interference features. We demonstrate experimentally that Talbot carpets can be imaged in a single exposure configuration revealing a broad spectrum of multi-scale features. We have performed rigorous diffraction simulations for showing that Talbot carpet print can produce ever-decreasing structures down to limits set by mask feature sizes. This demonstrates that large-scale pattern masks may be used for direct printing of features with substantially smaller scales. This approach is also useful for characterization of image sensors and recording media.

The global COVID-19 pandemic has transformed face masks from situational accessories to indispensable items in daily life, prompting a shift in public perception and behavior. While the relaxation of mandatory mask-wearing regulations is underway, a significant number of individuals continue to embrace face masks, turning them into a form of personal expression and identity. This phenomenon has given rise to the Fashion Mask industry, characterized by unique designs and colors, experiencing rapid growth in the market. However, existing research on masks is predominantly focused on their efficacy in preventing infection or exploring attitudes during the pandemic, leaving a gap in understanding consumer preferences for mask design. We address this gap by investigating consumer perceptions and preferences for two prevalent mask designs-horizontal fold flat masks and vertical fold flat masks. Through a comprehensive approach involving surveys and eye-tracking experiments, we aim to unravel the subtle differences in how consumers perceive these designs. Our research questions focus on determining which design is more appealing and exploring the reasons behind any observed differences. The study's findings reveal a clear preference for vertical fold flat masks, which are not only preferred but also perceived as unique, sophisticated, three-dimensional, and lively. The eye-tracking analysis provides insights into the visual attention patterns associated with mask designs, highlighting the pivotal role of the fold line in influencing these patterns. This research contributes to the evolving understanding of masks as a fashion statement and provides valuable insights for manufacturers and marketers in the Fashion Mask industry. The results have implications beyond the pandemic, emphasizing the importance of design elements in sustaining consumer interest in face masks.

Fiber Bragg gratings (FBGs) are the most compact and reliable method of suppressing atmospheric emission lines in the infrared for ground-based telescopes. It has been proved that real FBGs based filters were able to eliminate 63 bright sky lines with minimal interline losses in 2011 (GNOSIS). Inscribing FBGs on multi-core fibers offers advantages. Compared to arrays of individual SMFs, the multi-core fiber Bragg grating (MCFBG) is greatly reduced in size, resistant to damage, simple to fabricate, and easy to taper into a photonics lantern (PRAXIS). Multi-mode fibers should be used and the number of modes has to be large enough to capture a sufficient amount of light from the telescope. However, the fiber Bragg gratings can only be inscribed in the single-mode fiber. A photonic lantern bi-directionally converts multi-mode to single-mode. The number of cores in MCFBGs corresponds to the mode. For a writing system consisting of a single ultra-violet (UV) laser and phase mask, the standard writing method is insufficient to produce uniform MCFBGs due to the spatial variations of the field at each core within the fiber. Most significant technical challenges are consequences of the side-on illumination of the fiber. Firstly, the fiber cladding acts as a cylindrical lens, narrowing the incident beam as it passes through the air-cladding interface. Consequently, cores receive reduced or zero illumination, while the focusing induces variations in the power at those that are exposed. The second effect is the shadowing of the furthest cores by the cores nearest to the light source. Due to a higher refractive index of cores than the cladding, diffraction occurs at each core-cladding interface as well as cores absorb the light. As a result, any core that is located directly behind another in the beam path is underexposed or exposed to a distorted interference pattern from what phase mask originally generates. Technologies are discussed to overcome the problems and recent experimental results are presented as well as simulation results.

In the twenty-first century, one of the most controversial issues concerns neoliberal policies and its results. In particular, since the mid-1980s, the United States and international financial institutions have imposed their programs on Latin American countries. The result is a deepening social inequality in Latin America that puts an emphasis on financial stability instead of social security. Consequently, social inequality is worsened and an imbalance in income distribution took place. Because of the flexibility of labor, the middle class is destroyed. For the poor person deprived of the opportunity to rise, violence is a common occurrence in daily life. Thus, in this context, Eduardo Galeano raises the necessity of a critique concerning the values that neoliberalism regards as important. Furthermore, Galeano is also wary of the "militarization of neoliberalism." This is because the neoliberal multinationals motivate a war without borders under the guise of peace. Neo-liberal policies also contribute to environmental pollution. However, environmental vandalism, which happens in partnership with large and international organizations, is not readily apparent to the public because those perpetrators wore a "green mask." Hence, Galeano assiduously endeavors to undercover the false consciousness hiding behind the green mask. Thus, in brief summary, Galeano represents in his works a depiction about Latin America where violence often happens in daily life.

This study was a descriptive research on the level of self-care available to continous ambulatory peritoneal dialysis patients (hereinafter referred to as 'CAPD patient') related to the specific area of infection management. The method employed for the collection of data was a modified instrument of the self-care survey essentially based on Young Sook Choi's instrument. The relevant data was collected from september 1, 1996 to september 30, 1996. The subjects were provided with an open-ended question regarding the reasons behind why they did not seek self-care. The answers provided about self-care compliance were analyzed by SPSS for frequency, percentage, mean, t-test, ANOVA. Reasons for non-compliance were analyzed by content analysis. The results of the study were as follows : 1. The percentage of patients engaging in self-care were according to the following self performed tasks : preparation of dialysis : 30.58 points Dialysate exchange procedures : 49.40 points - Two bag type : 50.50 points - Spike type : 48.80 points - Neo type : 48.90 points Catheter exit site care : 25.13 points More specifically, in relation to the preparation of dialysis as referred to above, those patients engaging in self care was relatively high with respect to the cleaning of the dialysis before use and for the preservation of peritosol. However, in dialysate exchange procedures, data revealed that those patients engaging in self-care are relatively low with respect to putting on a mask during the performance of peritosol exchange. Similary in peritosol exchange procedure and catheter exit care, low levels of self-care performance were found in the area of putting on a mask during the peritosol exchange procedures and catheter line testing procedures, respectively. 2. In general characteristics, there appeared to be no distinction in self-care compliance among CAPD patients. 3. The main reasons for non-compliance were based in the following factor : intellectual, attitude, enviromental surrounding and physical. As a result of the foregoing finding, nurses should provide adequate assistance to promote self-care compliance by CAPD patients by checking the preparation of dialysis, dialysate exchange procedure, and catheter exit site care which recieved low point in this research.
