The purpose of this study is to pursue the way of human body expression for prospecting of future fashion illustration through research of the methods and meaning expressed in the works of 30 years by Antonio Lopez. The research was conducted by looking into the perception of the body between 1960s and 1980s, when Lopez worked actively, on the basis of the discourse, art and fashion for the femininity and studying the representation method and meaning of the body in his works. Lopez suggested an index of the ideal beauty of the times through the representation of the immature body like a child in the 60s, the glamorous body in the 70s and the exaggerated muscular body in the 80s by predicting the changes of the perception of femininity and ideal beauty. As the result of this research, it is found that Lopez employed the art form for the representation of the body in his works and presented the polysemous implications of the art form in the context of the body expression. In addition, he redefined sexuality by focusing on the code that confronted the conventional women's morals by changing the representation method of the women's pose, and depicted the other's image such as the colored races, departing from the ideal human body based on the white women. Lastly, he deconstructed the human body in various ways, thereby enlarging the concept of the human body in the existing fashion illustration.

A novel tunable transconductor is presented. Input transistors operate in the triode region to achieve programmable voltage-to-current conversion. These transistors are kept in the triode region by a novel negative feedback loop which features simplicity, low voltage requirements, and high output resistance. A linearity analysis is carried out which demonstrates how the proposed transconductance tuning scheme leads to high linearity in a wide transconductance range. Measurement results for a 0.5 ${\mu}m$ CMOS implementation of the transconductor show a transconductance tuning range of more than a decade (15 ${\mu}A/V$ to 165 ${\mu}A/V$) and a total harmonic distortion of -67 dB at 1 MHz for an input of 1 Vpp and a supply voltage of 1.8 V.

The preservation of temporal dependencies among a group of processes that exchange continuous media at runtime is a key issue for emerging mobile distributed systems (MDS), such as monitoring of biosignals and interactive multiuser games. Although several works are oriented to satisfy temporal dependencies, most of them are not suitable for MDSs. In general, an MDS is characterized by the absence of global references (e.g. shared memory and wall clock), host mobility, limited processing and storage capabilities in mobile hosts, and limited bandwidth on wireless communication channels. This paper proposes an asymmetric synchronization protocol to be used at runtime in an MDS without using a common reference. One main aspect of our synchronization protocol is that it translates temporal constraints to causal dependencies of the continuous media data as seen by the mobile hosts. We simulate the protocol by considering a cellular network environment and by using MPEG-4 encoders. The simulation results show that our protocol is effective in reducing the synchronization error. In addition, the protocol is efficient in terms of processing and storage costs at the mobile devices, as well as in the overhead attached per message across the wired and wireless channels.

In this paper, novel CMOS pseudo-exponential circuits operating in a class-AB mode are presented. The pseudo-exponential approximation employed is based on second order equations. Such terms are derived in a straightforward way from the inherent nonlinear currents of class-AB transconductors. The cells are appropriate to be integrated in portable equipment due to their compactness and very low power consumption. Measurement results from a fabricated prototype in a 0.5 ${\mu}m$ technology reveal a range of 45 dB with errors lower than ${\pm}0.5$ dB, a power consumption of 100 ${\mu}W$, and an area of 0.01 $mm^2$.

A systematic approach for the design of two-stage class AB CMOS unity-gain buffers is proposed. It is based on the inclusion of a class AB operation to class A Miller amplifier topologies in unity-gain negative feedback by a simple technique that does not modify quiescent currents, supply requirements, noise performance, or static power. Three design examples are fabricated in a 0.5 ${\mu}m$ CMOS process. Measurement results show slew rate improvement factors of approximately 100 for the class AB buffers versus their class A counterparts for the same quiescent power consumption (< 200 ${\mu}W$).

Background: To analyze the effects of the factors associated with different types of injury (superficial wounds, dislocations and sprains, bone fractures, concussion and internal injuries, burns scalding and freezing) caused by occupational accidents in automotive repair workshops. Methods: Study of a sample consisting of 89,954 industry accidents reported from 2003 to 2008. Odds ratios were calculated with a 95% confidence interval. Results: Belonging to a small company is a risk factor for suffering three of the five types of injury studied. Women are less likely to suffer burns and superficial wounds, and more likely to suffer dislocations or sprains. Foreign workers are more likely to suffer concussion and internal injuries. Conclusion: Health and safety strategies and accident prevention measures should be individualized and adapted to the type of worker most likely to be injured in each type of accident. Occupational health and safety training courses designed according to worker profile, and improving the participation of the workers in small firms creating regional or roving safety representatives would improve working conditions.

This work shows the impregnation of scents using a graphene sponge (GS). This was functionalized by the modified Hummers method, pursuing to add different functional groups. It is proposed to achieve the release and seek to control it through electrical potential applied to the graphene sponge with essential oils. The graphene sponge was functionalized and steeped with two kinds of oil. The electrochemical study demonstrates the variation in the electrochemical behaviour of the functionalized graphene sponge without and impregnated with oil. The release of the oil and its aromatic scents was carried out by applying an electrical potential of 30 V, with a release rate of 1.86 mg/min. The heating of the sample that causes the release of oil, associated with the electrical resistance of the system, reaches temperatures of about 150℃. The essential oils, graphene sponge, surfactant, graphene sponge with essential oils, graphene sponge recuperated after applying electric potential, graphene sponge recovered by temperature and dipropylene glycol (DPG) were characterized using Fourier transformed infrared spectroscopy (FTIR), digital microscopy, and x-ray photoelectron spectroscopy (XPS).

In this study fashion illustrations published in American Vogue from 1960 to 1989 were investigated. Among the large number of illustrations published in American Vogue in this period a considerable number of illustrations was chosen: from 1960 to 1969 143 editorial illustrations and 333 advertisement illustrations; from 1970 to 1979 34 editorial illustrations and 168 advertisement illustrations; from 1980 to 1989 123 editorial illustrations and 81 advertisement illustrations. In studying those illustrations the main point was put in finding characteristics and the changing trend of fashion Illustrations. In the sixties editorial fashion illustrations were published mainly during early sixties. The Illustrations of Rene Bouch, Evelyn Marcil, Dagmar and Eunice Moore Sloane took the space of editorials. Among those Illustrators Bouch published most frequently. The companies such as Galey & Lord, Lord & Taylor, Bergdorf Goodman, Bonwit Teller etc. used fashion illustrations for the advertisement. The name Kenneth Paul Block, Babara Pearlman and Dorothy Hood can be found very frequently on the illustrations for those companies. Antonio Lopez too published in 1963 some advertisement illustrations. In the seventies the total number of editorial fashion illustrations diminished drastically compared to the number in the sixties. Antonio published in 1973 and 74 fifteen illustrations, Joe Eula published from 1976 to 79 thirteen illustrations, and beside them Mats Gustavson published in 1978 six illustrations. The number of advertisement illustrations decreased a little, but many companies used fashion illustrations for the advertisement. The illustrator who worked most actively were Block and Fred Greenhill. In the eighties editorial illustrations experienced a "Renaissance". New high-level illustrators appeared and new fashion illustration magazines were found. Antonio played a central role among illustrators published for editorials in Vogue. In addition to him 15 other illustrators including Mats and Eula with various styles worked for editorials. In contrast to the flourishment of editorial illustrations the number of advertisement illustrations decreased compared to seventies as a result of the domination of fashion photography in this area. Today only few fashion illustrations can be found in fashion magazines. The magazines are dominated by fashion photographs. However fashion illustrations will not totally perish from fashion magazines, because it still has some valuable functions in fashion advertisement. Those functions cannot be fulfilled by photography. Therefore fashion illustration will survive in fashion magazine but playa minor role compared to photography.

We aimed to characterize the participation of rapid non-genomic and delayed non-genomic/genomic or genomic mechanisms in vasoactive effects to triiodothyronine (T3), emphasizing functional analysis of the involvement of these mechanisms in the genesis of nitric oxide (NO) of endothelial or muscular origin. Influences of in vitro and in vivo T3 treatments on contractile and relaxant responsiveness of isolated rat aortas were studied. In vivo T3-treatment was 500 ㎍·kg^-1·d^-1, subcutaneous injection, for 1 (T3_1d) and 3 (T3_3d) days. In experiments with endothelium-intact aortic rings contracted with phenylephrine, increasing concentrations of T3 did not alter contractility. Likewise, in vitro T3 did not modify relaxant responses induced by acetylcholine or sodium nitroprusside (SNP) nor contractile responses elicited by phenylephrine or angiotensin II in endothelium-intact aortas. Concentration-response curves (CRCs) to acetylcholine and SNP in endothelium-intact aortic rings from T3_1d and T3_3d rats were unmodified. T3_3d, but not T3_1d, treatment diminished CRCs to phenylephrine in endothelium-intact aortic rings. CRCs to phenylephrine remained significantly depressed in both endothelium-denuded and endothelium-intact, nitric oxide synthase inhibitor-treated, aortas of T3_3d rats. In endothelium-denuded aortas of T3_3d rats, CRCs to angiotensin II, and high K⁺ contractures, were decreased. Thus, in vitro T3 neither modified phenylephrine-induced active tonus nor CRCs to relaxant and contractile agonists in endothelium-intact aortas, discarding rapid non-genomic actions of this hormone in smooth muscle and endothelial cells. Otherwise, T3_3d-treatment inhibited aortic smooth muscle capacity to contract, but not to relax, in an endothelium- and NO-independent manner. This effect may be mediated by delayed non-genomic/genomic or genomic mechanisms.
