Analysis of the Region of Interest According to CNN Structure in Hierarchical Pattern Surface Inspection Using CAM.

A convolutional neural network (CNN), which exhibits excellent performance in solving image-based problem, has been widely applied to various industrial problems. In general, the CNN model was applied to defect inspection on the surface of raw materials or final products, and its accuracy also showed better performance compared to human inspection. However, surfaces with heterogeneous and complex backgrounds have difficulties in separating defects region from the background, which is a typical challenge in this field.

Estimating the phase volume fraction of multi-phase steel via unsupervised deep learning.

Advanced high strength steel (AHSS) is a steel of multi-phase microstructure that is processed under several conditions to meet the current high-performance requirements from the industry. Deep neural network (DNN) has emerged as a promising tool in materials science for the task of estimating the phase volume fraction of these steels. Despite its advantages, one of its major drawbacks is its requirement of a sufficient amount of training data with correct labels to the network.

Effect of Quenching Tempering-Post Weld Heat Treatment on the Microstructure and Mechanical Properties of Laser-Arc Hybrid-Welded Boron Steel.

In the present study, we have investigated the effect of post-welding heat treatment (PWHT) of quenching and tempering (QT) on the microstructure and mechanical properties of welded boron steel joints processed using laser-arc hybrid welding on two commercial filler materials, SM80 (Type-I) and ZH120 (Type-II). The microstructure and mechanical properties of the weld joints were characterized via optical microscopy, Vickers microhardness, and the uniaxial tensile test. The macrostructure of the weld joint was composed of a fusion zone (FZ), heat-affected zone (HAZ), and base metal zone (BMZ).

What causes the experience of discrimination in non-regular workers?

Background: Discrimination based on type of employment against non-regular workers is still a social issue. However, there are few studies on job factors that affect the discrimination experience in each type of employment or the association between discrimination and health impact indicators. This study examined occupational health characteristics according to discrimination experience and relating factors that affect discrimination experience.

Cardiac rehabilitation after acute myocardial infarction resuscitated from cardiac arrest.

Objective: To examine the safety and effectiveness of cardiac rehabilitation on patients resuscitated from cardiac arrest due to acute myocardial infarction.

Methods: The study included 23 subjects, including 8 with history of cardiac arrest and 15 without history of cardiac arrest. Both groups underwent initial graded exercise test (GXT) and subsequent cardiac rehabilitation for 6 weeks.

Impact of aerobic exercise training on endothelial function in acute coronary syndrome.

Objective: To confirm the improvement in arterial endothelial function by aerobic exercise training, flow-mediated dilation (FMD) was tested by ultrasonography.

Methods: Patients who received percutaneous coronary intervention due to acute coronary syndrome were included. The patients who participated in cardiac rehabilitation (CR) program were categorized as the CR group, and others who did not participate as the control.

Adaptive characterization of recrystallization kinetics in IF steel by electron backscatter diffraction.

In this study, a rigorous methodology for quantifying recrystallization kinetics by electron backscatter diffraction is proposed in order to reduce errors associated with the operator's skill. An adaptive criterion to determine adjustable grain orientation spread depending on the recrystallization stage is proposed to better identify the recrystallized grains in the partially recrystallized microstructure. The proposed method was applied in characterizing the microstructure evolution during annealing of interstitial-free steel cold rolled to low and high true strain levels of 0.

Comparison of Sono-guided Capsular Distension with Fluoroscopically Capsular Distension in Adhesive Capsulitis of Shoulder.

Objective: To investigate the short-term effects and advantages of sono-guided capsular distension, compared with fluoroscopically guided capsular distension in adhesive capsulitis of shoulder.

Method: In this prospective, randomized, and controlled trial, 23 patients (group A) were given an intra-articular injection of a mixture of 0.5% lidocaine (9 ml), contrast dye (10 ml), and triamcinolone (20 mg); they received the injection once every 2 weeks, for a total of 6 weeks, under sono-guidance.

C. elegans dystroglycan DGN-1 functions in epithelia and neurons, but not muscle, and independently of dystrophin.

The C. elegans dystroglycan (DG) homolog DGN-1 is expressed in epithelia and neurons, and localizes to basement membrane (BM) surfaces. Unlike vertebrate DG, DGN-1 is not expressed in muscle or required for muscle function.

The basement membrane components nidogen and type XVIII collagen regulate organization of neuromuscular junctions in Caenorhabditis elegans.

Vertebrate neuromuscular junctions (NMJs) contain specialized basal laminas enriched for proteins not found at high concentrations extrasynaptically. Alterations in NMJ basement membrane components can result in loss of NMJ structural integrity and lead to muscular dystrophies. We demonstrate here that the conserved Caenorhabditis elegans basement membrane-associated molecules nidogen/entactin (NID-1) and type XVIII collagen (CLE-1) are associated with axons and particularly enriched near synaptic contacts.
