Système de classementIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - OBJECTIVE : These were two folds: at first, to develop an automatic grading system specifically dedicated to some facial signs of men, similar to the one previously validated on women of different ethnic ancestry and second, to assess its potential in detecting and grading the possible impacts of a severe aerial urban pollution on some facial signs of Chinese men.
- METHODS : In both studies, selfie images were obtained from differently aged men. Nine facial signs were automatically graded through a specific A.I-based algorithm and clinically assessed by a panel of experts and dermatologists. Selfie pictures were taken from individual smartphones of variable optical properties. The first study, designed for developing an automatic grading system, involved three comparable cohorts of men from three different regional ancestries (African, Asian, Caucasian, 110 each) the selfie images of which were acquired under four different lighting conditions. As a second use case study, the facial signs of two cohorts of Chinese men (101 and 100, each), differently aged, regularly exposed to very different aerial urban pollution conditions (UP) were analysed by the same algorithm, selfies being taken under only one lighting condition.
- RESULTS :
- The new automatic grading system of facial signs suits well to men, showing comparable results than that the one dedicated to women and provides data in close agreement with experts’ assessments.
- In both cases (expert’s or automatic methodology), the accuracy of the scores appeared ethnic-dependent.
- The applied case confirmed previous results obtained clinically, that is, that many facial signs were found of an increased severity among men exposed to a severe urban pollution, as compared to those living in a less polluted city.
- In both studies, statistical agreements between the automatic grading system and expert’s assessments were reached. In some facial signs, the automatic grading system seems offering a slightly better accuracy than the assessments made by the experts.
- CONCLUSION : Apart from some minor limitations, this A.I-based automatic grading system, free from human intervention, performed as well as the one previously developed in women, in close agreement with expert’s assessments. In epidemiological studies, this system offers an easy, fast, affordable and confidential approach in the detection and quantification of male facial signs.Note de contenu : - MATERIALS AND METHODS : Subjects and conditions of provacy in the collection of smartphones selfie pictures (Study 1) - Facial signs analysed by automatic grading system (Studies 1 and 2) - Evaluation and grading of facial skinageing signs (Studies 1 and 2) - Principle of development of an automatic detection of facial signs from smartphone photographs (Study A) - Training and evaluation of the robustness of the automatic scoring system (Study 1) - Applied case on clinical impact of aerial urban pollution (UP in Chinese men (Study 2) - Statistics (Studies 1 and 2)

Économie circulaireL'économie circulaire est une expression générique désignant un concept économique qui s'inscrit dans le cadre du développement durable et s'inspirant notamment des notions d'économie verte, d’économie de l'usage ou de l'économie de la fonctionnalité, de l'économie de la performance et de l'écologie industrielle (laquelle veut que le déchet d'une industrie soit recyclé en matière première d'une autre industrie ou de la même).
Son objectif est de produire des biens et services tout en limitant fortement la consommation et le gaspillage des matières premières, et des sources d'énergies non renouvelables ;
Selon la fondation Ellen Mac Arthur (créée pour promouvoir l'économie circulaire1), il s'agit d'une économie industrielle qui est, à dessein ou par intention, réparatrice et dans laquelle les flux de matières sont de deux types bien séparés ; les nutriments biologiques, destinés à ré-entrer dans la biosphère en toute sécurité, et des intrants techniques ("technical nutrients"), conçus pour être recyclés en restant à haut niveau de qualité, sans entrer dans la biosphère

Régénération (biologie)Index. décimale : 668.5 Parfums et cosmétiques Résumé : Sandalwood extract (SW) is a natural biofunctional inspired by forest therapy to defy the skin olfactory signature of ageing. Obtained by supercritical CO2 extraction from santalum album, this unique and patented biofunctional leverages the forest bathing trend for well ageing benefits. SW enhances skin olfactory receptors shown to decrease with age and air pollution. It reduces skin cell senescence and helps mitigate air pollution damage. It has clinically proven benefits on skin regeneration, firmness, wrinkles, and on the skin olfactory signature of aging. SW is the first biofunctional developed with artificial intelligence.

"apprentissage machine"), apprentissage artificiel ou apprentissage statistique est un champ d'étude de l'intelligence artificielle qui se fonde sur des approches mathématiques et statistiques pour donner aux ordinateurs la capacité d'"apprendre" à partir de données, c'est-à -dire d'améliorer leurs performances à résoudre des tâches sans être explicitement programmés pour chacune. Plus largement, il concerne la conception, l'analyse, l'optimisation, le développement et l'implémentation de telles méthodes. (Wikipedia)

Industrie 4.0Le concept d’Industrie 4.0 correspond à une nouvelle façon d’organiser les moyens de production : l’objectif est la mise en place d’usines dites "intelligentes" ("smart factories") capables d’une plus grande adaptabilité dans la production et d’une allocation plus efficace des ressources, ouvrant ainsi la voie à une nouvelle révolution industrielle. Ses bases technologiques sont l'Internet des objets et les systèmes cyber-physiques.

Photoprotection
Photovieillissement (dermatologie)Index. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : To summarize key research published by the author's group, dealing with skin photoaging and its photoprotection.
- Materials and Methods : Two methodologies (standard photographs and selfies imaging) resulting from referential skin ageing atlases were applied on 2487 subjects of different ancestries, ages and gender. These aimed at first to best assess and grade the variable severities of some facial signs (texture/wrinkles, pigmentary spots, sagging and vascular disorders) that occur progressively during the photoaging process. Second, such methodologies were used to record the benefits brought by a photoprotective regimen (671 women and men).
- Results : In all studied ancestries, each facial sign show an increase severity along decades, at its own pace, some showing a linear like progression, whereas some plateau at early ages. These changes differed according to skin innate colour (phototype) and with individual behaviours vis-Ã -vis sun exposures, more so among European women than North-East Asian women. An effect of gender (less severe alterations) was observed on Chinese men, as compared to Chinese women. Pigmentary disorders were found hallmarks of photo-aged North-East Asian women. Globally, photoaging impact the apparent age of the different subjects.
The counteracting effects of strong topical Photoprotective regimens were evidenced along a 6-month seasonality in Chinese and French women or 1-year period in Brazilian women with phototypes II to VI. Photoprotection led to a more even skin complexion among Indian subjects with pigment irregularities.
- Conclusion : Two factors clearly hamper a better assessment of the efficiency of photoprotection of the sun-induced cutaneous ageing: short durations (months) of the studies with regard to the global fate of photoaging by decades and the number of studied subjects, limited to hundreds for practical reasons. The methodology based on the automatic analysis of facial signs through selfies images could theoretically bypass both factors, allowing thousands of subjects to be studied along years.Note de contenu : - MATERIALS AND METHODS : Methodologies - Subjects - Clustering procedure for sun-phobic and non-sun-phobic groups - Qualify and quantify impact of photoprotective regimen
