Texte intégralRésumé :
In the last twenty years, studies in Afro-American slavery have given special attention to the slave community and culture. They have emphasized the slaves' control over their lives, while glossing over the brutality of the institution of slavery. Slave women have been ignored until very recently, and those few historians who studied their lives have applied the same categories of inquiry used by traditional historians with a male perspective. The topic of interracial sexual relations crystallizes this problem. This issue has been left aside in most scholarly studies and, when mentioned, addressed more often than not from a male perspective. As sexual abuse, it exemplifies the harshness of slavery.
The oral slave narratives, often referred to by the same historians, are one of the few primary sources by and on slave women. Yet, historians have not used them adequately in research on slave women, primarily because of inadequate conceptual frameworks.Master of Arts

Simendic, Marko. « Hobbes on persona, personation, and representation : behind the mask of sovereignty ». Thesis, University of York, 2011. http://etheses.whiterose.ac.uk/1986/.
Texte intégralRésumé :
This thesis explores Thomas Hobbes’s idea of a person and personation. More particularly, it aims to uncover what it means for Hobbes to (re)conceptualise political representation as “bearing” of a certain person. This is especially important because Hobbes uses this notion to describe the relationship between the sovereign and their subjects. There are three aspects to the research undertaken. Firstly, this account discusses a number of intellectual sources that Hobbes relied on in crafting his idea of a person. To this end the thesis tackles Cicero’s conception of persona as well as various legal and theological sources that have marked the medieval development of this idea. The second aspect of the thesis deals with Hobbes’s definition of a person and its relationship with his definition of the state. Here it is argued that the contemporary commentators have misread Hobbes’s definition of a person and mistakenly identified Hobbes’s commonwealth with it. In response, this thesis offers a more sophisticated definition of a person and places the Hobbesian “person of the state” in its proper place: as the defining, although not the only element of the commonwealth. The third aspect of the thesis addresses the role of Hobbes’s account of representation in his wider political theory. This role is twofold. Firstly, personation describes the relationship between a number of principal agents in Hobbes’s political philosophy: God, the sovereign(s) and the subjects. Secondly, the theatrical nature of Hobbesian personation might suggest another way of approaching Hobbes’s political theory. This is a multi-perspectival approach that conceptualises human agency and mutual interaction as inseparable from its perception. The concluding part of the thesis deals with the way in which the three dimensions of Hobbes’s account come together and form a potent argument in favour of absolute and unitary authority.

The corona pandemic has led to the implementation of non-pharmaceutical interventions by governments worldwide. The use of face masks limits the spread of the COVID-19 virus and mask mandates are a prominent tool of public health policy. However, this measure is highly politicized and abidance to mask mandates is crucial for the efficiency of face masks. Here, I present the results of an observational study on the abidance to mask mandates at tram stops in Leipzig, Germany. Based on logistic mixed effects regression models, I show that abidance to mask mandates was generally low, with a mask-wearing rate of 33%. However, mask-wearing was more prominent in situations with an increased risk of infection (high 7 day incidence and numerous people at the tram stops). My results contradict the high abidance to mask mandates of 90% found in surveys and highlights the rationality behind mask-wearing behavior

Tsiamis, Andreas. « Electrical test structures and measurement techniques for the characterisation of advanced photomasks ». Thesis, University of Edinburgh, 2010. http://hdl.handle.net/1842/4296.
Texte intégralRésumé :
Existing photomask metrology is struggling to keep pace with the rapid reduction of IC dimensions as traditional measurement techniques are being stretched to their limits. This thesis examines the use of on-mask probable electrical test structures and measurement techniques to meet this challenge and to accurately characterise the imaging capabilities of advanced binary and phase-shifting chrome-on-quartz photomasks. On-mask, electrical and optical linewidth measurement techniques have highlighted that the use of more than one measurement method, complementing each other, can prove valuable when characterising an advanced photomask process. Industry standard optical metrology test patterns have been adapted for the direct electrical equivalent measurement and the structures used to characterise different feature arrangements fabricated on standard and advanced photomasks with proximity correction techniques. The electrical measurements were compared to measurements from an optical mask metrology and verification tool and a state-of-the-art CD-AFM system and the results have demonstrated the capability and strengths of the on-mask electrical measurement. For example, electrical and AFM measurements on submicron features agreed within 10nm of each other while optical measurements were offset by up to 90nm. Hence, electrical techniques can prove valuable in providing feedback to the large number of metrology tools already supporting photomask manufacture, which in turn will help to develop CD standards for maskmaking. Electrical test structures have also been designed to enable the characterisation of optical proximity correction to characterise right angled corners in conducting tracks using a prototype design for both on-mask and wafer characterisation. Measurement results from the on-mask structures have shown that the electrical technique is sensitive enough to detect the effect of OPC on inner corners and to identify any defects in the fabricated features. For example less than 10 (5%) change in the expected resistance data trends indicated a deformed OPC feature. Results from on-wafer structures have shown that the correction technique has an impact on the final printed features and the measured resistance can be used to characterise the effects of different levels of correction. Overall the structures have shown their capability to characterise this type of optical proximity correction on both mask and wafer level. Test structures have also been designed for the characterisation of the dimensional mismatch between closely spaced photomask features. A number of photomasks were fabricated with these structures and the results from electrical measurements have been analysed to obtain information about the capability of the mask making process. The electrical test structures have demonstrated the capability of measuring tool and process induced dimensional mismatches in the nanometer range on masks which would otherwise prove difficult with standard optical metrology techniques. For example, electrical measurements detected mismatches of less than 15nm on 500nm wide features.

Texte intégralRésumé :
From the 1960s, through the Black Arts Movement, until her sudden death in December 2012, Jayne Cortez used her dynamic voice to fight oppression. as the first multiple-chapter study of Cortez’s musical collaborations, this dissertation adds to a growing body of critical work that examines Cortez’s radical poetry. In her “African Confluences” keynote address at Rutgers University, Cortez described herself as a member of a global community of black writers “protesting and calling for an end to self degradation, self fragmentation, self-corruption, and self-fear and selfishness… Poets using the image of Blackness to mean continuity, confidence, creativity and new possibilities.” Cortez created new possibilities through her collaborations with artists and writers across the African diaspora, including American free jazz musicians who worked alongside traditional West African master musicians. Cortez traveled extensively and cultivated lifelong relationships with musicians who challenged boundaries between artistic genres to create a distinctly kinetic form of jazz-inflected poetry that gave voices to black Americans and people displaced across the African diaspora. Cortez’s sustained collaborations with Bill Cole, Denardo Coleman, and her Firespitters band produced unparalleled multivocal cross-genre conversations that embodied the collective spirit of jazz improvisation. “‘When I Put on My Firespitter Mask’: Jayne Cortez’s (R)Evolutionary Musical Poetic Collaborations” offers a chronological analysis of selected collaborative performances and recordings with musicians. Beginning with her earliest collaborations, Cortez’s poetry blended elements of surrealism, Pan-Africanism, ecofeminism, performative poetics, and black vernacular music into dialogic calls to action that embodied diasporic community building through harmolodic improvisation and musical call and response. This dissertation applies the aforementioned theoretical frameworks to close readings and historical contextualization of multiple revisions of eleven poems, including poems published in out-of-print chapbooks, studio recordings, live recordings, unreleased live performance recordings, and uncatalogued documents such as poem drafts, journals, and handwritten performance notes located in fifteen boxes Cortez donated to the Schomburg Center for Research in Black Culture. The appendices provide the most comprehensive timeline and list of Cortez’s publications available to date, with the intention of providing points of departure for forthcoming critical explorations of Cortez’s archive of over 400 poems and more than ninety recorded musical collaborations.

Ohlsén, Tina. « Lifting the mask on tuberculosis : distribution of notified cases in Stockholm County 1989 to 1996 ». Thesis, Karolinska Institutet, 1999. http://urn.kb.se/resolve?urn=urn:nbn:se:rkh:diva-58.
Texte intégralRésumé :
In order to investigate the distribution and burden of tuberculosis (TB) in Stockholm County during the period 1989 to 1996, a descriptive study was conducted. The TB cases registered in the central TB register during that period were studied. Demographic profiles, geographic distribution, disease presentation and diagnosis of registered TB cases were described. During 1989 to 1996, 1022 TB cases were registered in Stockholm County accounting for 23% (1022/4487) of all TB cases in Sweden during that period. The crude annual incidence was stable, oscillating between 7,1 and 8,1 per 100 000 population. Stratification by national origin showed a decrease of the annual incidence from 4,3 to 3,3 cases per 100 000 in the Swedish born population and an increase from 149,4 to 238,9 among the Africa borns. The overall age distribution of 1022 cases showed a bimodal pattern, peaking among young adults aged 25 to 44 years and among the elderly above 64 years. Stratification by age showed a declining trend in the age group above 64 years. In this age group the proportion of Swedish born was 85%. An increasing trend was observed in the age group 18 to 24 years. In this age group 91% were foreign born. The median age declined from 61 years during 1989 to 37 during 1996. The average annual incidence varied in the different municipalities between 1,3 (Ekerö) and 10,7 (Sundbyberg)per 100 000 population. The highest average annual incidence was found in Spånga parish. Due to an increased number of Africa born TB cases, the annual incidence in Spånga increased three-fold from 18,1 to 48,0 per 100 000 population. Nearly two-thirds (63) of the cases had pulmonary TB, 16% had lymphatic TB and 21 % had other extra –pulmonary lesions. The site of disease showed gender and ethnic differences. Lymphatic TB was more common in females, while pulmonary and other extra- pulmonary TB were more common in males. The highest proportion (42%) of lymphatic TB was found among Asian female cases compared to 4% in the Swedish male cases. Crude county incidence does not reveal geographic and ethnic clustering of TB cases. Clinical manifestations of TB vary depending on sex and ethnic differences. As being a low-incidence county, Sweden could be well suitable for TB eradication. To achieve such goal, the national TB control program need to be restructured in order to facilitate cluster oriented interventions.

ABSTRACT Each country has a special culture of the mask, masks bring unlimited imagination, the most prominent of the highest human achievements of the "drama" to express the story directly and presence. From five ancient culture to modern civilization, all through the use of masks to render this inhuman realm of the non-reality, the mask of culture can be said that the east-west and up and down time and space. Relative to the East to the color and shape to distinguish between good and evil, the West, Venetian masks, but by the protection of the mask to cover up the gap between the rich and the poor, the boundaries between good and evil, everyone is equal under the cover of masks. The annual Venice Mask Festival, the crowd all by opportunities for celebration, the culmination of the use of a variety of organic lines, dazzling decorations and overall shape to show creativity. This study is to understand the general public awareness and image of the mask creation, specifically to know why the general public for the mental image of the mask shape creation, as the basis for promotion of creative masks, and as a creative production enthusiasts reference. The study used a survey method, 12 researchers created creative mask works for the observed production questionnaire using semantic differential method, non-random samples were collected through a questionnaire survey, a total of 284 valid questionnaires recovered will be effective The questionnaire data entry SPSS12.0 statistical package twist to the analysis of questionnaire data. The results show that gender relates to the respondents liked the creative masks, but age is a key, age of respondents for the preferences of creative masks change, if the respondents had contact with the mask creation, different performance the more favorite creative mask-making, these findings can be used as future reference to promotion of mask-making. Key Words: mask, creation, creativity

In this study, we investigate the x-ray mask technology on SiC membrane and TaSi or TaSiN absorbers. Silicon carbide film was deposited by electron resonance plasma enhanced chemical vapor deposition (ECR-CVD). The reactive gases were silane and methane, and the carrier gas was Argon. We utilized the Taguchi Methods to analyse the parameters for depositing SiC film, and determine the optimum condition. The methane flow rate, microwave power and stage position are the main effect of the film growth rate. The as-deposited stress of membrane and absorber films were compressive, and turned into low tensile stress by thermal annealing process. The tri-layer structure of oxide/absorber/oxide can fabricate the fine pattern with 0.16μm linewidth by Cl2 gas.

Photolithography is the preferred method of micro-patterning in both electronics manufacturing and micro-electromechanical systems (MEMS). The process normally requires a customized mask to be manufactured, which is too expensive, time consuming, and flexibility limited. In order to solve these problems, a special maskless lithography system (MLS) has been developed. The MLS applies Digital Micro-mirror Device (DMD) of the digital light processing (DLP) to generate the mask pattern on the substrate. And the previous study of the MLS mainly focuses on enhancing resolution instead of mass production. Therefore, the image combination of multiple DLP has been developed in this study. With the sequential imagines and light uniformity adjusted by software, the large-area scale exposure of MLS on PCB has achieved. The results of the experiments have successfully incorporated the combination of images and improved light uniformity. With the image scaled down to one sixth, the optimal resolution of the exposure is 85 ?慆. And with two scaled-down-images combination, doubling single scaled-down area form 42.6 mm times 32 mm to 42.6 mm times 60 mm, the separate circuit patterns projected by two DLP are successfully united and exposed.

In recent years, science and technology changes rapidly, the development of computer technology has been used in the manufacture for many years. In the manufacturing sector is increasingly widely used. The advantage is that it simplifies the production of complex workpieces, and no additional molds are required, greatly reducing the time and cost of product design. Designers use computer software to design object models, after the software output image file, and then enter the image file to the machine can directly produce the design of objects. This production process facilitates the design or modification of the model and is therefore responsive to in all areas the rapid development of molding requirements. This research focuses on the development of additive manufacturing software, suitable for DLP (Digital Light Processing) manufacturing of the 3D printer. DLP technology belongs to the additive manufacturing, the higher precision of a manufacturing forming mode. The first step for the production processes is using of CAD software design object model, through the additive manufacturing software for layering. The second step is by the 3D solid model into a two-dimensional profile and further converted into a mask. The final step is input to the DLP form of the 3D printing machine for object forming print. The design of the model is composed of many triangular meshes on the surface of the object, so the grid density of the model will directly affect the accuracy of the product. When the grid of the model is denser, the precision of the printed products is closer to the original design the model. In this research, we use the compensation of the mask to print the missing parts of the forming object, and the files read by the DLP machine are printed for the picture file. This study also uses pixel different gray value processing for object printing analysis, can make the object edge smoother. In this research, the five average dimension error percentages of the square 5 * 5, 10 * 10, 15 * 15, 20 * 20, 25 * 25 (mm) are reduced by about 1.5%. In the hollow object, the 20 * 20 mm object is discussed in detail, and the dimensional error is reduced by about 2%. In the edge smoothness of the object, the Ra. value is reduced by about 1.2um.

This study employees fractals to inspect the defects of cloth masks. Since the surface textures of the cloth mask and its defects are different, the use of fractals is a suitable approach to detect defects on masks. The mask image is firstly captured by a CMOS vision system. Next, we develop image preprocessing techniques to filter out noises and search for the mask counter, including color space transformation, two-dimension Gaussian filter, region growing method and image thinning method. The color space transformation is used to obtain luminance of the mask image. The cooperation of the one-dimension Gaussian filter and the region growing method is used to make the mask counter smooth and continuous. The cooperation of the Otsu’s two-level method and the image thinning method is employed to search for the coordinates of the mask counter. Based on the fractal geometric theory, we develop a differential box-counting method to detect the defects of cloth masks. Finally, experiments on practical masks show effectiveness of our proposed methods.

There are diverse visual designs of commodity package in the current market. Package design has become the most effective tool in the marketing strategies of products. With the main intention to attract consumers, the package design of masks is considerably important. Designers keep creating new packages to highlight the characters of products by the differentiation of package design, so as to show the vitality of products and trigger the consumption desire. Therefore, the key of marketing and designing is how to impact consumers favorably by packages. The study aimed to explore the information related to the visual design of mask package by literature review and current situation survey, and provide reference for the further studies on visual image of mask package and for the marketing and designing practitioners in the relative application. Through the method of semantic differential, the study explored and analyzed the current demands and impressions of consumers on the product packages based on the statistical results of questionnaire survey, and collected packaged of various brands as the researching samples. It found that the students, workers and housewives averagely spend less than NT$ 500 on masks every month. As for the purchasing channel, most of the consumers prefer the living house, followed by pharmacy. What’s worth mentioning is the online shopping has gradually become a main channel of mask purchase. It’ s also found from the color research that hydrating masks are commonly in blue, brightening masks are in white or pink, and firming masks are in yellow.

The facial mask is booming in Taiwan market, and the trend is tent to use natural plant extraction as ingredient. Therefore, this study selects Plectranthus amboinicus Lour., a Taiwan traditional plant which is usually used to treat inflamed skin or relieve redness and swelling of the skin, to be used in the product ingredients, adopting dosage type of facial mask agent as the main idea of the research. The experiment was used through extracting different water source, comparing the difference of the activity among the extract liquor, and performing the antioxidant experiments, such as the clearance rate of DPPH, antioxidant capacity of ABTS and cation, and the measurement of total phenols content. This study used the method of patch test to test the safety of extract liquor on human bodies, and stimulated the phenomenon of the erythema on skin by using cinnamon essential oil to test the effect of eliminating erythema of the extract liquid. The ingredient was applied in the products to create two products with different dosage types of mask agents, combining grease and pure water in proportion to create two emulsion masks with high moisture degree, and adding the polymeric thickener with pure water base to create a refreshing water mask. Comparing two kinds of masks and integrating the detector being used for detecting the skin type of full face, the detector for whitening the skin, the detector for detecting skin moisture, and questionnaires about sense for products into validity evaluation for products. According to the activity evaluation, total phenol content and the effect of eliminating erythema of extract liquid, it is found that different extract liquids with different solvents can make different activity effects, and the capacities of erythema elimination varied in different solvents also can produce different effects. It is found from product effectiveness evaluation that emulsion mask include the extract liquor has significant improvements on porse, texture, red areas and moisturizing degree; The while water mask include the extract liquor has better efficiency on porphyrins and brightness degree of full face, and the result of sensory test of emulsion mask is close to that of water mask. According to the results of this study, it is shown that using appropriate dosage forms of mask agent aiming at different types of skin condition could promote the efficiency of products.

This study aims to embed watermark based on the dot gain properties of outputted halftone images. Digital halftoning reduces the gray levels by quantizing contone images into binary images affecting the robustness and security of watermark embedding. In addition, the capacity of information hiding in halftone image is limited. The blue noise mask (BNM) is the state of art of digital halftone technique, which employs the characteristics of higher cut-off spectrum frequency to meet the perceptional quality of human visual system. However, images halftoned by BNM causes larger dot gain because of its frequency modulation distribution, which may result in outputted image darker and less pleasant in visual perception. Moreover, the green noise mask (GNM) inherited not only from BNM’s spectrum characteristic but also from dot gain aspect of the printer model by varying the dot size where provide the possibility of positions for watermark to be embedded in images halftoned by GNM. The study attempts to embed watermark by toggling the value of pixels in halftone image. The embedding positions are decided depend on the degrees of dot gain compensation. The performance of the method is demonstrated by a number of experiments that can keep embedded images’ visual qualities and watermarks’ security, robustness and imperceptibility.

Extreme ultraviolet lithography (EUV) is one main technology of the new generation lithography. Because of the fast development of integrated circuits, the width dimension required in processing is smaller and smaller. EUV lithography is considered as one of the great methods for the new generation. However, in the process of semiconductors, it will cause the printing errors and increase the costs with any defect in the mask. Therefore, an inspection system of mask defect should be build. In this study, we try to build the inspection system in National Synchrotron Radiation Research Center in Hsinchu and use the beamline19A1 in that place for this system light source. We design and build an EUV mask inspection in a vacuum chamber at the end-station for providing detection defects in the mask.

Skincare products have traditionally been seen as a beauty aid and focused primarily on the female consumer. However, in today’s modern times women are no longer the only ones concerned about how they look. Men realize that their individual appearance can dramatically alter their self-image as well as impact other people’s perception of them. As men become more cognizant of these realities regard- ing appearance they begin search for ways to improve or enhance their facial features. Although there is a heightened awareness and emphasis on appearance by males, there are very few male-specific skincare products in the marketplace. Along with a lack of products there is a lack of male oriented skincare information. As a result, it is commonplace for a man concerned with his appearance to use skin care products that were originally intended for females. This is an incorrect approach to male skincare because there are numerous gender specific differences in male and female skin types. This makes a male’s skin more prone to sweating and oilier than a female’s. Also, skin issues that confront men and women are vastly different. As noted by one entrepreneur, this gender gap in skincare products has created a demand and is an excellent opportunity for companies in the cosmetic and skincare industry. It is time for these companies to invest in research and development of Products that cater specifically to a man’s special needs. This study looks at the facial mask industry from a manufacturer’s perspective and applies Blackwell, Miniard, & Engel’s CDP model as the foundation of the research. The findings are analyzed to determine male facial mask purchase behavior, motivation, information sources, purchase considerations, and consumer demographics. This data can be used by facial mask manufactures to help them develop an understanding of the factors men consider important when making a purchase decision. This newfound understanding can be applied to create more effective future sales and marketing strategies by the manufacture.

Currently, it is very expensive or hard to produce a full stage “golden plate” for large area mask fabricators to calibrate their stage of the exposure tool. Furthermore, it is lack of recessive calibration data or theoretical information for implementing calibration processes for the metrology tool to measure large area mask to meet the requirement of customers in semiconductor industry. Roughly, there are 2 reasons: First, it is very difficult to order or get the suitable “golden plate”. The price is too high. Second, the technology generation is pushed faster and faster. The lifetime of each generation becomes shorter and shorter. The “golden plate” of former generation tool is no lounger larger enough in full stage calibration for current generation tool to meet the requirements of large area mask customers. The research proposes a simple and practical methodology of metrology and calculation for large area mask exposure machine. The proposed innovative methodology was generated by many series of experimental tests and supported by least squcure statistical method. The metrology and verification software has been developed and evaluated based on large amount of measured data from on line metrology machine for about a year. Applying this methodology, the expected calibration performance shows that it is no longer limited by full stage “golden plate” for large area mask exposure machine. The big advantage is that the expensive metrology tool is not necessary the only choice for the calibration of large area mask exposure tool. Several experiment data results demonstrate and prove the methodology is accurate, reasonable and suitable on current higher accuracy exposure and metrology tools for IC masks. The proposed methodology has been applied to on line large area mask fabrication. The practical performance and the customer’s appreciated feed back have also demonstrated the efficiency and usefulness of the innovative metrology and calibration methodology.

In this paper, computational fluid dynamics (CFD) method is used to simulate a global flow field in the military protective mask and to explore aerodynamic characteristics of the flow field inside the military respirator. Identify the impact factors that influence the internal flow field in the overall pressure drop and flow structure of the masks. As the reference of configuration improvements and reach the lower respiratory piezoresistive enhance wearing comfort. The simulation of the entrance inlet flow is set to the conditions 15, 30, 80, 85, 110 and 135L/min. The governing equation is the three-dimensional steady state Reynolds average Navier-Stokes equation, and the low Reynolds number - turbulence mode is embedded in the governing equations for the average air age in order to determine the standard space dead zone and the air age. The results show that the most important parameter impacts the respirator's aerodynamical characteristics is the distribution and number of the inlet holes. In the Model D, the average flow of inlet air is 85L/min, the pressure drop in the nasal cavity is 176Pa, compared with the one of Model A, which is under the same inlet conditions, is 691Pa, 515Pa is reduced and the decline is up to 75%. The purpose of breathing comfort is achieved by the lower nasal respiratory pressure drop than the one designed with the jaw at a single inlet mask. On the other hand, study results of Model A and Model B show that in the same kind of respiratory conditions, the Model B with 97 canisters has the more maximum voltage drop value of the canister and the additional work of breathing than the Model A with 62A type. The decline is up to 40%. To take the safety of personnel into consideration, the 97 type of the canister can be replaced the 62A-type canisters serving in the military right now.

In this study, we examined the adsorption and release of oleuropein (OLE) against silk fibrion mask in three different solutions( deionized water, 50% methanol, and methanol) by high performance liquid chromatography (HPLC) method. In the first part¸ we prepared the oleuropein standard solution. A standard curve of oleuropein accordig to the detected data of HPLC was constructed. Next, we prepared the crude OLE extract from the oleuropein powder extracted by methanol. The purity of OLE was determined as about 9.97%. In the second part, we examined the the stability of oleuropein in various solutions. Two acidic solution, formic and acetic acid in a different concentration (0.1M, 1M solution and pure acid), were prepared to undergo oleuropein hydrolysis under three temperature conditions of 95、65 and 35±2℃. The result showed that the highest stability of oleuropein is in the conditions of lower concentration and lower temperature of acetic acid solution.; In the third part, we examined the adsorption of oleuropein on the silk fibroin paper-like mask(SFPM) under different solutions. Three different solutions (deionized water, 50% methanol, and methanol) and each with three different concentrations of OLE extract(50、30 and 10mg／mL)were prepared. SFPM cut into each piece of 1 c㎡size and weighted 4.2 ± 0.2mg of every small piece was subjected to batch immersion at room temperature. The resultant SFPM piece and the remaining solutions were checked for the amounts of oleuropein by HPLC. The result showed that the best adsorption was in the condition of higher concentration and longer immersed time in deionized water. Conversely, lower concentration and shorter immersed time in methanol showed the poorest adsorption; In the fourth part, we examined the released amount of oleuropein by a simulated control release method. 1.0mg of dried SFPM after adsorption was homogenized into small pieces, and put into 1mL of eppendorf tube. The release of OLE in three different solutions ( pH = 5.6 buffer, 95% ethanol, and 1:1 mixture of buffer and ethanol) was detected in water bath at 37 ± 2 ℃, for short and medium-range of time. The results indicated that the release of OLE reached the maximum amount after three hours of incubation in the three solutions. By comparing the ratio of released/adsorbed OLE under each condition, it is indicated that the release efficiency exhibited the best in the buffer solution, while the least in 95% of ethanol solution.

Stability and comfort of CPAP nasal mask is very important for obstructive sleep apnea(OSA) treatment. Wearing nasal mask with CPAP machine can provide oxygen supplement, positive pressure, humidifier, and atomizing air. In addition, nasal mask is simpler and more convenient for using and promotion. Although there are so many strengths of nasal masks, skin tissue ulceration and pressure sore around the bridge of the nose are often heard among CPAP users. This article defines criteria of good nasal masks which reduce the shearing force and friction on the skin while wearing, and decrease the chance of air leakage and getting red marks or occurrence of pressure sores on your face. Therefore, a well-designed nasal mask not only improve compliance of using CPAP but also enhance OSA treatment. The burden and waste of medical resources can be reduced at the same time if pressure sores are not happened. This research method is divided into three stages. The first stage is evaluating the existing good-selling masks. The second stage is to define the greatest innovative design for Taiwanese. Through the design analysis and integration, combined with the test and the discussion in the second chapter, the innovative nose mask design can be defined. The third stage is mask testing. The tester will have few different pressure test points where the silicone pads contact the tester’s face and come out an assessment analysis. Through the third stage of comparison between innovative design nasal mask and current best-selling nasal masks, innovative design mask can significantly reduce pressure and treatment improvement. Meanwhile, there are no difference between male and female testers, so there is no need to create different sizes among genders. The result of 30 testers’ questionnaire about nasal mask’s usage and comforts shows this new design mask’s operation is simple and intuitive. The adjustable headband is smooth and effective. For comfort assessment, it has good stability and no excessive pressure on the face. The innovative nasal mask can improve the compression and comfort of wearing.

In recent years, under the rapid development of the integrated circuit manufacturing industry, the scale miniaturization of the lithography process has become one of the most important issues. In modern semiconductor process technology, people develop resolution enhance techniques continually, and optical proximity correction has also received attention. However, the actual process steps will interactively affect the final appearance of the model. For this reason, we use an artificial neural network to analyze the results and use nonlinear dimensionality reduction to reduce the amount of model training, thus reducing the model training time. Using Isometric Mapping (ISOMAP) and Uniform Manifold Approximation and Projection (UMAP) to reduce the dimension of the input mask data, the computation time of the artificial neural network reduced from 4803 s to 68 s, and the mask pattern is used to predict the etching result by the model. The model facilitates the design of the mask for this structure in the future. However, the use of dimensionality reduction will make a little distortion. Therefore, the co-ranking matrix is used to quantify the amount of distortion, and the local continuity meta-criterion is calculated to evaluate the difference between different dimensionality reduction methods. The data of the same mask pattern is simplified by different methods, and the UMAP distortion is lower than ISOMAP.

There are several works of Mishima Yukio which are telling about homosexuality, such as “Confessions of a Mask”. When describing a man to another man’s secret love, the narrator “I” described sharply the conflicts among men’s society. Although “Confessions of a Mask” is related to homosexuality, it didn’t have any intercourse scene. In this work, the narrator used “bad habit” to describe the pleasant feeling from imaging men’s body, but used “love” to describe the feeling of Kiss with women. It is interesting about the difference between the thought to men and women, and this kind of story could be saw in Mishima Yukio’s other works. Especially the work “Forbidden Colors” was thought as the sequel to “Confessions of a Mask”, the relationship between these two works is also an important key point. Hence, this thesis would use the work “Confessions of a Mask” and “Forbidden Colors” to analyzing the narrator’s thought between men and women, and find out the relationship between the narrator and Mishima Yukio. Furthermore, there are several issues would be analyzed in this thesis. In Hashimoto Osamu’s thesis, he thought “Shunsuke” and “Yuichi” could be seen as the same person. What is the reason? Mishima Yukio’s works often wrote about the change of relationship between homosexual and women (to rely on and be relied on). Therefore, how the female characters of “Forbidden Colors” could change their role from relier to be relied on in the Patriarchy society is a topic in this thesis. The difference between homosexual and men would be mentioned as well. I would analyze these issues above and discover that Mishima Yukio’s works have what kind of influence to his sequel works.

Texte intégralRésumé :
It has only been within recent decades that the complexity and heterogeneity of the biofilm mode of bacterial existence has been widely appreciated. Biofilms have persisted for billions of years as social communities of cells aggregated and attached on surfaces, and today they are both necessary and harmful within the human body and our surrounding environment. They show extremely high antibiotic resistance relative to planktonic cells and are sources of persistent infections. Biofilms are also the most common cause of failure for indwelling biomedical devices and implants. As a result, research efforts and commercial developments are focusing on creating better biomaterials that prevent bacterial attachment to surfaces leading to biofilm formation. While chemical methods to combat bacterial infections have been around for over a century in the form of antimicrobials, relatively little is known about how topographical methods can prevent bacterial attachment to surfaces. The reason for this is that micro- and nano-scale fabrication technologies (which are needed to produce topographies on size scales that might be expected to influence bacterial attachment) are fairly recent developments.
In this thesis work, microscale topographies were developed for probing and influencing bacterial attachment to surfaces using dynamic-mask multiphoton lithography. Multiphoton lithography is an inherently three-dimensional fabrication technique. When combined with the dynamic-mask-based technology developed in the Shear laboratory, it allows for rapid prototyping of 3D structures of arbitrary complexity with submicron resolution in the radial dimension.
A variety of topographical approaches for influencing bacterial attachment of Pseudomonas aeruginosa cells were explored within this work. P. aeruginosa was selected as a model organism for biofilm formation and because it is commonly isolated from infections associated with biomedical implant devices. Topographical approaches included the design of topographies based on microscale surfaces of naturally-antifouling leaves and mathematical functions, pillars, and surfaces containing various sizes and geometries of holes. Challenges relating to an imaging artifact caused by light scattering induced by the surfaces shed light on issues associated with assessing bacterial attachment levels on microscale topographical surfaces. Finally, future directions for this work are presented with ideas that extend into the nanoscale regime.text

For traditional semiconductor fabrication process, photo resist is often used as shield layer in etching process. However, it has some problems unsolved to be used in etching process as future sizes or CD rdeaching to nano meters regimes. Therefore, hard mask of the other materials is use as shield layer. For DRAM fabrication process, tungsten lines are made by plug method when CD are larger than 110 nano meters. However, it would have vacancy to induce high resistance. And gas molecules used in process and their byproducts like WF6 、H2、F and HF would be scratched to vacancy. And such gas chemicals will diffuse to etch metal, broke devices, and diminish reliability of chips. Therefore, as CD less than 90 nano meters, tungsten lines are etched directly. However, traditional photo resists can not match needs of etching process. Such that hard mask like silicon oxide is used instead of. When using silicon oxide as hard mask, microloading effect due to decreasing chip sizes would be serious. It would cause tungsten lines patterned uncorrectly. Even open circuit would happen. Therefore, to obtain the process parameters like RF power, ratio between O2 and CF4/CHF3 contractions, flow rate of Ar, and pressure to control CD and prevent microloading effect are investigated in this thesis.

To propose a way to solve the problem of poor selectivity of SnO2 semiconductor gas sensors was the goal of this research. The sensing devices utilized in this research were fabricated by screen printing. Three layers, namely the sensing layer, the insulation layer, and the filtering layer, were printed on the device. The materials of the layers were SnO2, SiO2, and SnO2 respectively. Methane and ethanol were the model gases in this study. The effects of covering the SnO2 sensing layer with an insulation SiO2 layer and with layers of SiO2 plus SnO2 were studied. Also investigated were the effects of adding Cr, Mn, Fe, Co, or Cu to the SnO2 filtering layer. A diffusion model was proposed in this research. The model was used to simulate the transport of ethanol in the filtering layer and to examine the blockage effect of the layer to ethanol. As indicated by the experimental data, masking the sensing layer with an insulation SiO2 layer could increase the in air resistance and the in 1000 ppm CH4 sensitivity of the sensor. The SiO2 layer could also lowered the temperature of maximum sensitivity from 400℃ to 350℃. Comparing to an unmasked device, a SiO2 masked sensor had about an order higher sensitivity in 1000 ppm EtOH at 300℃. In addition, the SiO2 mask could also decrease a sensor’s methane to ethanol selectivity and give the sensor a constant response time when sensing 1000 ppm CH4 at above 350℃. Comparing to a two-layer (insulation and sensing) sensor, a three-layer (filtering, insulation, and sensing) sensor had a much lower sensitivity in 1000 ppm EtOH, higher methane to ethanol selectivity, and about the same in air resistance and in 1000 ppm CH4 sensitivity. A straight line was obtained on a logarithm paper by plotting the sensitivity versus methane concentration data obtained at 500℃ from a three-layer sensor. A curve was obtained when the gas was changed to ethanol. The sensitivity of a three-layer sensor in 4000 ppm CH4 was 11.2 , lower than the 12.6 in 4000 ppm EtOH. The response time of a three-layer sensor was found inversely proportional to the concentration of methane. Adding Cr, Mn, Fe, Co, or Cu to SnO2 filtering layer could only slightly affect the sensitivity of a three-layer sensor in 1000 ppm CH4. However, the addition could remarkably change the sensitivity when the gas was switched to ethanol. The effect of the additives on the sensor’s methane to ethanol selectivity were in the order: Cu @ Mn > Fe @ Cr > Co > none. A straight line was obtained on logarithm paper by plotting the sensitivity against methane concentration data generated at 450℃from a three-layer sensor with Mn-SnO2 filtering layer. A curve was obtained when the gas was switched to ethanol. The sensitivity of the three-layer sensor with Mn-SnO2 filtration layer for 4000 ppm EtOH was 9.8. The number was about the same as the 9.7 for 200 ppm CH4.

With a view to prolonging fire escape times and ensuring more rescue or evacuation opportunities, the present paper proposes the design of a multi functional fire escape mask based on Kansei engineering. First,expert interviews were conduced to investigate the experts’ viewpoints of what design factors constitute a good escape mask. Their opinions help solve problems with fire escape and reduce fire-related injuries or fatalities. For data analysis, the author first adopts Nagai’s 5W1H, which collects all relevant design data of the multi-functional fire escape mask.The new mask is then subject to comparison with “general masks” as to the design terms. The best design factors are obtained through this process. Then, the researcher applies Interpretive Structure Model to analyze the graph path of each design structure. Afterwards, the author implements Local Grey Relational Analysis- Analytical Hierarchy Process to process the consensus assessment of optimized structure design strategy. The sorting of the optimized design graph path is thus derived from this method. Also, the analysis manifests the decisive design factors pertaining to the multi-functional fire escape mask. Such a device not only meets the needs of the general public but also serves as a guide which Kansei device designs can refer to. By referring to this study,products can be more practical and market-oriented due to their good quality and function. They can become a household necessity and satisfy the general public’s psychological needs.

As the technique of storage media and Internet develops rapidly in recent years, the demands for video are not only quality but also interaction. The conventional video coding standard, such as MPEG1, MPEG-2, and H.263 cannot satisfy the demands mentioned above .The MPEG-4 video coding standard is the first one to support randomly accessing video objects by the concept of video-object-plane (VOP). It can support high interaction and more flexible coding. Therefore, segmenting the shapes of the video objects is very important. Many video object segmentation algorithms have been presented. They can be summarily classified into two types: (1) Temporal Analysis and (2) Temporal-Spatial Analysis. One typical kind of Temporal Analysis is to get the moving information of video objects between two continuous frames on the temporal domain. Although these methods have lower computation load, the quality of segmentation is not good enough. Because the objects needed to be segmented are easily to be influenced by brightness or shadow, some kinds of typical method combine spatial and temporal domain was proposed [14]. This approach uses the algorithms of edge detection to get the shapes of the foreground objects and find out the edge of moving regions by using the analysis on the temporal axis, and then, the filling technique is used to generate the masks of the foreground objects. Although this method has higher robustness and better quality for segmentation, the similarity between the original video objects and masks depends on the chosen morphological structuring element and times of processing during the process of filling masks by using morphological operations. If we choose a complex structuring element, it will raise the computation load and reduce the efficiency of the system. In order to overcome the mentioned shortcomings, we propose a new algorithm by adding a pre-processing mechanism to improve the object segmentation. A new video object segmentation algorithm using the morphological technique is proposed. Several video object segmentation algorithms used mathematical morphology to generate the object masks, but operations of mathematical morphology have two drawbacks: (1) high computation load, and (2) the quality of masks depends on the chosen morphological structuring element. There are many techniques to speed up the morphological operations by hardware implementation, but no discussions are found about reducing the influence of the choice of structuring elements. By adding a pre-processing mechanism, we effectively reduce the influences of the chosen structuring elements based on continuity of shape features and times of morphological operations. Experimental results indicate that our algorithm can improve the speed of filling operations of the object masks and accuracy of segmentation

For the sub-14nm technology node, triple patterning lithography (TPL) is adopted, which decomposes a single layer into three masks to increase pitch and enhance the resolution. In routing stage, considering TPL can improve the flexibility of layout decomposition. Moreover, layouts with balanced density can reduce edge placement error(EPE)[2]. This work considers the mask density balancing based on triple-patterning lithography aware detailed router[6] to improve the printability. Swapping pseudo colors and density aware stitch generation are proposed to balance mask density. The result shows that there is the trade-off between stitch counts and additionally considering the local density constraint besides the global density constraint.

Generative adversarial networks promote a variety of development for the reason that GAN can learn the distribution of given training samples and yield synthetic samples via adversarial training. The vanilla generative adversarial networks is the combination of two independent networks. The generative network is to synthesize fake samples, and the discriminative network is used to evaluate the relevance between fake samples and real ones. In the existing approaches of object transformation based on generative adversarial networks without giving paired images and annotating the object of interest in the training and testing phases, the synthetic images of theirs would have significant color change in the region we are not desired to translate at all, such as background. In our proposed method, for the purpose of reducing color distortion in the background and remaining the same manual annotation cost, we aim to generate rendering masks via residual connections in the generative network, and take their uniformity into consideration in the optimization process to preserve the original contents of background without any paired training data and predefined region. As demonstrated in our experimental results, the qualitative and quantitative evaluation exceed previous works, as well as our approach can efficiently decrease artifacts and conspicuously preserve more visual information in the region of background in regard to the visual perception in comparison with alternative methods.

In the past of few years, not only women but also men are care about there skin, especially on their face. With the promo show up on TV shows and advertisings, there are more and more people have a skin-care-conscious. This conscious become one of the habits in our life, consumers are willing to spend more money for take care their skin on the face. Which by the way, the younger generations are becoming the potential consumer in facial mask industrial. Therefore, this research would based on the market of facial mask in Taiwan to build the research model. This model is including Consumer Involvement, Brand Equity, Perceived Risk and Purchase Intention.

The research develops a machine vision to inspect the C-type mask. The image process technique is divided into two parts. The first part is an image preprocess, including color space transformation, image filtering and morphology. The second part is defect inspection, including image positioning and image subtracting. The main objective to achieve inspecting C-type mask automatically. There are there types of defects of C-type mask, including holes, dirty spots, bad soldering. First, we use image preprocessing to detect the outlines of masks. Then, the corner detection is employees to obtain the characteristics of the outlines. Those characteristics are compared with the characteristics of standard mask. The defects of test images are thus defected through the subtracting images. Finally, the proposed method is used to inspect practical C-type masks, and the results show that the proposed method can obtain successful recognition of C-type mask defects.

NIST (National Institute of Standard Technology) selected Rijndael as the new Advanced Encryption Standard (AES) in 2001. Experts in every field try their best to introduce new style of attack to break AES standard. In hardware point of view, when hardware module is executed, it may reveal information indirectly about the cryptographic device due to many kinds of physical phenomena, like length of execution time, power consumption, and electromagnetic dissipations, etc. Using this kind of information to attack cryptographic device is called Side-Channel Attack (SCA). Therefore, even if one cryptographic algorithm is proved secure, it may reveal protected secret as a result of various implementation factors. An attacker can collect power curves dissipated by cryptographic device and analyze them. This kind of attack is called power attack and is proposed by Kocher in 1999. Therefore recently many papers are published to defend power attack. The most common method is to randomize intermediate value of each round, so that 'Mask' is discussed extensively. This kind of method is to conduct random number to what you want to hide. Thereby, attackers are not able to collect and analyze power curves, hence power attack will be useless. In this thesis, we will review power attack, implement Oswald's mask architecture based on the properties of Dual Cipher, and discuss whether it is better than Oswald's masking method. We will also analyze whether Dual AES combines mask may lead better security to defend power attack.
