Dental caries is one of the most prevalent infectious diseases in Indonesia. More than half of all cases are left untreated. This may be due to inequity in the use of dental care that is caused by economic and geographic barriers. Therefore, the objective of this study was to provide evidence of socioeconomic-related inequality and horizontal inequity in dental care utilization among Indonesian...

Reconstructing 3D facial geometry from a single RGB image has recently instigated wide research interest. However, it is still an ill-posed problem and most methods rely on prior models hence undermining the accuracy of the recovered 3D faces. In this paper, we exploit the Epipolar Plane Images (EPI) obtained from light field cameras and learn CNN models that recover horizontal and vertical 3D ...

BACKGROUND Out-of-pocket spending is an important source of healthcare financing even in countries with established prepaid financing of healthcare. However, out-of-pocket payments (OOPP) may have undesirable effects from an equity perspective. In this study, we analyse the distributive effects of OOPP in Austria based on cross-sectional information from the Austrian Household Budget Survey 200...

OBJECTIVE To study the intrinsic fertility of the human oocyte. DESIGN A large retrospective study of natural cycle single embryo transfer (ET) IVF cycles. SETTING Private IVF clinic, university, and private hospital. PATIENT(S) Patients were enrolled consecutively over an 8-year period in a single ET natural cycle protocol. INTERVENTION(S) A total of 13,949 oocyte retrievals with natur...

OBJECTIVE The purpose of this study was to evaluate the relation between idiopathic scoliosis and facial deformity in the horizontal, vertical, and anteroposterior planes. METHODS A total of 123 female patients aged 14 years or older, who visited the Spine Clinic at the Department of Orthopedics, Korea University Guro Hospital for treatment of idiopathic scoliosis, were enrolled. Whole-spine ...

Experiments suitable for classroom projects or demonstrations are described concerning the aerodynamics of polystyrene balls. A light ball with sufficient backspin can curve vertically upward through the air, defying gravity and providing a dramatic visual demonstration of the Magnus effect. A ball projected with backspin can also curve downward with a vertical acceleration greater than that du...

PURPOSE To determine whether face perception can be equalized across the visual field by scaling size and contrast simultaneously. METHODS Contrast sensitivities were measured for detection (N = 1) and identification (N = 2-8) of a target face as a function of size (0.4 degrees-10 degrees) across eccentricities (E = 0 degrees-10 degrees). RESULTS In all conditions contrast sensitivity first...

BACKGROUND To investigate the association between pretreatment corneal parameters and orthokeratology lens decentration. METHODS This retrospective study included a total of 108 eyes in 60 myopia patients, who were divided into a lens-decentration and a control group. Various pretreatment corneal parameters were analyzed by receiver operating characteristic curves (ROC curves), including corn...

We explain how species accumulation curves are influenced by species richness (total number of species), relative abundance and diversity using computer-generated simulations. Species richness defines the boundary of the horizontal asymptote value for a species accumulation curve, and the shape of the curve is influenced by both relative abundance and diversity. Simulations with a high proporti...

Transition curves with monotone curvature profile are widely applied in fair curve design. Advantage of using transition curve is that it can avoid the undesirable curvature extrema. Demonstration of transition curve in designing surface of revolution, particular of vase design can be often seen in literature. For these demonstrations, authors mainly focused on the curvature control of the vase...
