Ironing is one of troublesome houseworks, in which the goal of the task is to remove wrinkles caused during washing. A projector has advantages in physical world instruction over an instruction sheet, a Head Mounted Display, or a smartphone/tablet PC because of direct mapping of instructive information on the target object. In this article, we propose a method to detect wrinkles using machine-l...

In computer graphics, one of the important factors for rendering realistic human bodies is quality of skin. To improve this, it is necessary to represent small wrinkles on skin surfaces, which are locally oriented to certain directions. However, no method is developed to generate wrinkles over body parts like hands or arms, taking into account local directions. Thus, this paper proposes a metho...

Currently, alternatives to prebiotics for skin treatment are receiving much interest. However, little is known about the efficacy of topically applied prebiotics in skin anti-aging. This study was conducted to observe the anti-aging effects of DuOligo, which is composed of lactulose and galactooligosaccharides (GOS). We investigated wrinkle-related parameters by quantitative and qualitative ski...

BACKGROUND In phytotherapy, the therapeutic potential is based on the combined action of different herbal drugs. Our objective was to evaluate the antioxidant, anti-collagenase (in vitro), and anti-wrinkle (in vivo) effect of combined formulation containing Ginkgo biloba, Punica granatum, Ficus carica, and Morus alba fruits extract. METHODS Antioxidant evaluation was based on the scavenging a...

INTRODUCTION Among non-ablative devices for wrinkle reduction and skin laxity, long pulsed 1064 nm Nd:YAG laser (LPND) has considerable effectiveness. It can penetrate to deep dermis due to its longer wavelength. This study assesses the efficacy and safety of LPND applying new parameters for skin rejuvenation in Korean subjects. METHODS A prospective randomized split-faced study was done (n =...

BACKGROUND The number of existing wrinkle assessment scales makes it difficult to compare the efficacy of cosmetic techniques in rejuvenating photoaged skin. A single and simple assessment scale that reliably quantifies wrinkle depth is needed. OBJECTIVE The objective was to validate the Modified Fitzpatrick Wrinkle Scale (MFWS) as a nasolabial wrinkle severity assessment tool. METHODS AND ...

The sheep blowfly is an economically important ectoparasite of sheep, and impacts on animal health and welfare under pastoral conditions in South Africa. The absence of flystrike in the breech (ABS) was recorded in 2198 Merino hoggets on the Tygerhoek Research Farm. This trait was analysed together with dag score (DS; n=1623); neck wrinkle score (NWS; n=2162); midrib wrinkle score (MWS; n=2162)...

BACKGROUND/PURPOSE Does the morphology of wrinkles alter gradually with aging or suddenly at a certain age? On the basis of the theoretic wrinkle simulation of ideal skin, we have suggested that the wrinkle morphology suddenly changes from stratum corneum wrinkling to epidermis wrinkling; the former induces shallow fine furrows, and the latter induces deep prominent wrinkles. To examine the exi...

Wrinkle structures in rocks younger than the Permian-Triassic (P-Tr) extinction have been reported repeatedly in marine strata, but rarely mentioned in rocks recording land. Here, three newly studied terrestrial P-Tr boundary rock succession in North China have yielded diverse wrinkle structures. All of these wrinkles are preserved in barely bioturbated shore-shallow lacustrine siliciclastic de...

This paper presents a detailed experimental study of the evolution and shape of reversible corrugations, or wrinkles, in initially flat, linear-elastic and isotropic thin foils subject to in-plane loads. Two sets of experiments were carried out, on a rectangular membrane under simple shear and on a square membrane subjected to two pairs of equal and opposite diagonal forces at the corners. Sali...
