Raster-stereography is a 3D surface topography technique, which provide height and curvature information of the subject. This is a non-contact, non-invasive and radiation free technique, which is mostly used to analyze the back shape of human body. The most practical aspect of raster-stereography is ease in its apparatus setup and reduced exposure to x-rays. Another very important and effective application is to identify the human faces that can be used in security domain. The problem of breaking lines was observed while traversing the distorted raster pattern on human body. These breaks in raster pattern increased significantly when projected on the face. Computationally it becomes difficult to extract all valid curvatures of the human face. This problem was resolved using a modified dotted raster and the noise effect was reduced substantially. The dotted raster technique proved that it is by far the best option when compared with the conventional line grid.

There is, to all appearances, a philosophic hostility to fashionable dress. Studying this contempt, this paper examines likely sources in philosophy's suspicion of change; anxiety about surfaces and the inessential; failures in the face of death; and the philosophic disdain for, denial of, the human body and human passivity. If there are feminist concerns about fashion, they should be radically different from those of traditional philosophy. Whatever our ineluctable worries about desire and death, whatever our appropriate anger and impatience with the merely superficial, whatever our genuine need to mark off the serious from the trivial, feminism may be a corrective therapy for philosophy's bad humor and self-deception, as these manifest themselves when the subject turns to beautiful clothes.

This chapter considers the types of weapon that are the subject of certain specific Protocols under the CCW. The text of each of these CCW Protocols is analysed to determine the range of weapons and activities covered by the instrument and to interpret the obligations that the Protocol introduces. The first Protocol discussed is the Protocol on Non-Detectable Fragments, which prohibits the use of any weapon the primary effect of which is to injure by fragments which in the human body escape detection by X-rays. The chapter then turns to the Incendiary Weapons Protocol, which prohibits certain activities altogether while limiting the circumstances in which others may be lawfully undertaken. The discussion concludes with an overview of the Laser Weapons Protocol, whose main operative provision is to prohibit the employment of laser weapons specifically designed as a combat function to cause permanent blindness to unenhanced vision.

The general objective of this study is to analyze the postulate of the ethics of otherness as the first philosophy, presented by Emmanuel Levinas. It is a proposal that runs through Levinas' thinking from his theoretical foundations, to his philosophical criticism. Levinas' thought presents itself as a new thought, as a critique of ontology and transcendental philosophy. For him, the concern with knowledge and with being made the other to be forgotten, placing the other in totality. Levinas proposes the ethics of otherness as sensitivity to the other. The subject says here I am, making myself responsible for the other in an infinite way, in a transcendence without return to myself, becoming hostage to the other, as an irrefutable responsibility. The idea of the infinite, present in the face of the other, points to a responsibility whoever more assumes himself, the more one is responsible, until the substitution by other.

AbstractWith the rapid development of gymnastics technology, novel movements are also emerging. Due to the emergence of various complicated new movements, higher requirements are put forward for college gymnastics teaching. Therefore, it is necessary to combine the multimedia simulation technology to construct the human body rigid model and combine the image texture features to display the simulation image in texture form. In the study, GeBOD morphological database modeling was used to provide the data needed for the modeling of the whole-body human body of the joint and used for dynamics simulation. Simultaneously, in order to analyze and summarize the technical essentials of the innovative action, this experiment compared and analyzed the hem stage of the cross-headstand movement of the subject and the hem stage of the 180° movement. Research shows that the method proposed in this paper has certain practical effects.

The aim of this study is to demonstrate the use and the effectiveness of cephalometry and golden proportions analysis of the face in planning prosthetic treatments in totally edentulous patients. In order to apply this method, latero-lateral and posterior-anterior X-rays must be performed in addition to the common procedure. Two main concerns for totally edentulous patients are the establishment of the vertical dimension and the new position of the occlusal plane. The divine proportion analysis was carried out by the use of a golden divider. The prosthetic protocol was divided into three steps and a case was selected for better understanding. Referring to the golden relations, if the distance from the chin to the wing of the nose is 1.0, the distance from the nose to eye is 0.618. This proportion is useful and effective in determining the correct prosthetic vertical dimension. The incisal margin of the lower incisor must be positioned between Point A (A) and protuberance menti (Pm) according to the gold ratio 0.618 of the total height A-Pm. Posteriorly the occlusal plane must be placed 2 mm below the divine occlusal plane (traced from the incisal margin of lower incisors to Xi point). A prosthesis made in accordance with cephalometric parameters and divine proportions of the face helps to improve the patient’s aesthetics, function and social personality.

Abstract Background While ablative techniques have been standard of care for the treatment of fine lines and wrinkles, microneedling is a minimally invasive alternative. Objectives The purpose of this study was to assess the efficacy of microneedling on facial and neck fine lines and wrinkles. Methods 35 subjects between 44 and 65 years old with Fitzpatrick skin types I-IV received four monthly microneedling treatments over the face and neck. Subjects returned one and three months post-treatment. At every visit, high-resolution ultrasonography, optical coherence tomography, transepidermal water loss and BTC-2000 were performed. 0.33mm microbiopsies were collected pre-treatment, before the fourth treatment and three months post-treatment. Results 32 subjects (93.75% female, 6.25% male) completed all seven visits. Facial dermal and epidermal density increased 101.86% and 19.28%, respectively from baseline at three months post-treatment. Facial elasticity increased 28.2% from baseline three months post-treatment. Facial attenuation coefficient increased 15.65% and 17.33% one and three months post-treatment. At study completion, blood flow 300µm deep decreased 25.8% in the face and 42.3% in the neck. Relative collagen type III and elastin gene expression was statistically higher three months post-treatment. However, total elastin protein levels unchanged compared to baseline. 58% of biopsies extracted three months post-treatment showed dermal muscle formation, compared to baseline 15.3%. Conclusions The results illustrate the effects of microneedling treatments. Non-invasive measurements and biopsy data showed changes in skin architecture and collagen/elastin gene expression suggesting skin rejuvenation, with new extracellular matrix production and muscle formation.

AbstractIdentity as traditionally conceived in mainstream Western thought is focused on theory, representation, knowledge, subjectivity and is centrally important in the works of Emmanuel Levinas. His critique of Western culture and corresponding notion of identity at its foundations typically raises the question of the other. Alterity in Levinas indicates existence of something on its own account, in itself independently of the subject’s will or consciousness. The objectivity of alterity tells of the impossible evasion of signs from their destiny, which is the other. The implications involved in reading the signs of the other have contributed to reorienting semiotics in the direction of semioethics. In Levinas, the I-other relation is not reducible to abstract cognitive terms, to intellectual synthesis, to the subject-object relation, but rather tells of involvement among singularities whose distinctive feature is alterity, absolute alterity. Humanism of the other is a pivotal concept in Levinas overturning the sense of Western reason. It asserts human duties over human rights. Humanism of alterity privileges encounter with the other, responsibility for the other, over tendencies of the centripetal and egocentric orders that instead exclude the other. Responsibility allows for neither rest nor peace. The “properly human” is given in the capacity for absolute otherness, unlimited responsibility, dialogical intercorporeity among differences non-indifferent to each other, it tells of the condition of vulnerability before the other, exposition to the other. The State and its laws limit responsibility for the other. Levinas signals an essential contradiction between the primordial ethical orientation and the legal order. Justice involves comparing incomparables, comparison among singularities outside identity. Consequently, justice places limitations on responsibility, on unlimited responsibility which at the same time it presupposes as its very condition of possibility. The present essay is structured around the following themes: (1) Premiss; (2) Justice, uniqueness, and love; (3) Sign and language; (4) Dialogue and alterity; (5) Semiotic materiality; (6) Globalization and the trap of identity; (7) Human rights and rights of the other: for a new humanism; (8) Ethics; (9) The World; (10) Outside the subject; (11) Responsibility and Substitution; (12) The face; (13) Fear of the other; (14) Alterity and justice; (15) Justice and proximity; (16) Literary writing; (17) Unjust justice; (18) Caring for the other.

Background:Pyogenic spondylodiscitis (SPD) is a serious infection of an intervertebral disc and/or adjacent vertebrae, that remains a topical problem in rheumatological practice. Early diagnosis and treatment are the only guarantees of a favorable outcome. Clinicians must strive to isolate the responsible bacteria in order to adapt the treatment, and thus reduce the risk of resistance and complications due to SPD itself, but also to the multiplication of probabilistic treatments.Objectives:Our aim was to study the contribution of the different microbiological and anatomopathological examinations in the diagnosis of pyogenic SPD.Methods:It was a descriptive study in a single rheumatology department. Data were collected retrospectively from observations of patients hospitalized in the past 20 years who have been diagnosed with pyogenic SPD. We excluded cases of tuberculous and brucellar SPD from our study because of their completely different histological and microbiological profiles.Results:Twenty-two cases of pyogenic SPD were collected (14M/ 8F). The mean age of the population was 55.9 years [29,80]. A bacteriological survey including at least one cytobacteriological examination of the urine (CBEU), chest X-rays and blood cultures allowed the identification of the bacteria in 16 cases (73%). The most common site were bacteria was identified was blood culture in 7 cases, skin sample and urine collection in 2 cases each. Disco-vertebral puncture and biopsy (DVPB) was performed in 19 patients when there was no bacteria identification and/or when diagnosis of infectious SPD persisted doubtful. On histopathological examination, were described: an infiltrate and/or inflammatory changes without specificity signs in 7 patients and an appearance of chronic pyogenic SPD very likely in 12 patients. Bacteriological study of DVPB fluid or paravertebral abscesses sample helped to isolate bacteria in 4 patients. DVPB or abscesses puncture were contributing by histological and/or bacteriological examination in 12 patients (63%).Infecting bacteria was identified in 14 patients (64%). Gram-negative bacilli (GNB) and staphylococcus aureus were the most frequent germs (7 cases each) including 2 cases of co-infection. GNBs were represented by: Escherichia Coli and Enterobacter Cloacae in 2 cases each, Proteus Mirabilis, Serratia Marcescens and Klebsiella oxytoca in 1 case each. Clostridium clostridioforme and Lactococcus cremoris were isolated in 1 case each. For patients whose etiological investigation remained negative, SPD diagnosis was retained based on imaging (MRI) guided by anamnestic, clinico-biological and histopathological arguments.Conclusion:SPD is a rare condition that needs to be treated rapidly. Once the diagnosis is suspected, bacteria must be isolated before starting any antibiotic therapy. Simple and non-invasive exams as blood cultures, CBUE and chest rays, should be undertaken first. In fact, these simple exams allowed a germ identification in 73% cases in our study. If doubt persist, DVPB could be contributive to the diagnosis.References:NoneDisclosure of Interests:None declared
