Comparing the Effects of Face-to-face and Video-based Education on Inhaler Use: A Randomized, Two-group Pretest/posttest Study

Background: The quality of inhaler use can significantly affect the effectiveness of inhalation medications. This study was done to compare the effects of face-to-face and video-based education methods on inhaler use. Materials and Methods: A quasi-experimental, pretest/posttest clinical trial study was conducted on 120 patients with respiratory diseases who were under treatment with metered-dose inhalers. Patients were randomly allocated into two groups to receive either face-to-face (n = 60) or video-based education (n = 60) about correct inhaler use. Inhaler use was assessed using a 15-item checklist before, 2 weeks, and 1 month after the education. Chi-square and independent sample t-test as well as repeated-measures analysis of variance were used for data analysis. Results: At baseline, the groups did not differ significantly in inhaler use as shown by the mean score (t = 0.81, p = 0.33). Repeated-measures analysis showed that the mean score of inhaler use significantly increased in both groups 2 weeks and 1 month after the intervention (F = 585.07, p < 0.001). The t-test showed that at 2 weeks and 1 month after intervention the amount of increase in the face-to-face group was significantly greater than the video-based group (t = 3.31 and 5.93, p < 0.001). Conclusions: Both face-to-face and video-based education methods significantly improve inhaler use, even though the effects of the face-to-face method are significantly greater. Nurses can use either of these two methods or both for education of patients about inhaler use.
Comprehensive analysis of key genes, microRNAs and long non‐coding RNAs in hepatocellular carcinoma

Human hepatocellular carcinoma (HCC) is a common aggressive cancer whose molecular mechanism remains elusive. We aimed to identify the key genes, microRNAs (miRNAs) and long non‐coding RNAs (lncRNAs) involved with HCC. We obtained mRNA, miRNA and lncRNA profiles for HCC from The Cancer Genome Atlas and then identified differentially expressed mRNAs (DEmRNAs), miRNAs (DEmiRNAs) and lncRNAs (DElncRNAs). We performed functional annotation of DEmRNAs and then constructed HCC‐specific DEmiRNA–DEmRNA, DEmiRNA–DElncRNA and DElncRNA–DEmiRNA–DEmRNA interaction networks. We searched for nearby target cis‐DEmRNAs of DElncRNAs and performed receiver operating characteristic and survival analyses. A total of 1239 DEmRNAs, 33 DEmiRNAs and 167 DElncRNAs in HCC were obtained. Retinol metabolism [false discovery rate (FDR) = 7.02 × 10−14] and metabolism of xenobiotics by cytochrome P450 (FDR = 7.30 × 10−11) were two significantly enriched pathways in HCC. We obtained 545 DEmiRNA–DEmRNA pairs that consisted of 258 DEmRNAs and 28 DEmiRNAs in HCC. mir‐424, miR‐93 and miR‐3607 are three hub DEmiRNAs of the HCC‐specific DEmiRNA–DEmRNA interaction network. HAND2‐AS1/ENSG00000232855–miR‐93–LRAT/RND3, ENSG00000232855–miR‐877–RCAN1 and ENSG00000232855–miR‐224–RND3 interactions were found in the HCC‐specific DElncRNA–DEmiRNA–DEmRNA interaction network. A total of three DElncRNA–nearby target DEmRNA pairs (HCG25–KIFC1, LOC105378687–CDC20 and LOC101927043–EPCAM) in HCC were obtained. Diagnostic and prognostic values of several selected DElncRNAs, DEmRNAs and DEmiRNAs for HCC were assessed. Our study identified several DEmRNAs, DEmiRNAs and DElncRNAs with great diagnostic or prognostic value for HCC, which may facilitate studies into the molecular mechanisms, and development of potential biomarkers and therapeutic target sites for HCC.
Semantic Human Matting

Human matting, high quality extraction of humans from natural images, is crucial for a wide variety of applications. Since the matting problem is severely under-constrained, most previous methods require user interactions to take user designated trimaps or scribbles as constraints. This user-in-the-loop nature makes them difficult to be applied to large scale data or time-sensitive scenarios. In this paper, instead of using explicit user input constraints, we employ implicit semantic constraints learned from data and propose an automatic human matting algorithm Semantic Human Matting(SHM). SHM is the first algorithm that learns to jointly fit both semantic information and high quality details with deep networks. In practice, simultaneously learning both coarse semantics and fine details is challenging. We propose a novel fusion strategy which naturally gives a probabilistic estimation of the alpha matte. We also construct a very large dataset with high quality annotations consisting of 35,513 unique foregrounds to facilitate the learning and evaluation of human matting. Extensive experiments on this dataset and plenty of real images show that SHM achieves comparable results with state-of-the-art interactive matting methods.
Nutrient Intakes Status and Physical Inactivity among Overweight and Obese School Children in Kota Bharu, Kelantan, Malaysia

Background: The study examined the baseline findings of a controlled intervention study comprising anthropometric measurements, nutrient intakes, and physical activity among overweight or obese children in Kota Bharu, Kelantan, Malaysia. Methods: The study was completed in 2016 and the baseline data were gathered from four groups in a school-based randomized community trial among Year Five students from primary schools in Kota Bharu, Kelantan, Malaysia. Participants completed anthropometry assessment, three-day dietary record, and Physical Activity Questionnaire for Older Children (PAQ-C). Results: The prevalence of obesity was higher among the boys (52.5%). Mean energy intake was significantly higher among boys as compared to the girls (P=0.003). Twenty-five percent of the participants had exceeded the recommended nutrient intakes (RNI) of energy recommended. The calcium, thiamine, riboflavin, and niacin were also significantly higher among boys as compared to the girls (P<0.05). Boys also exhibited a significantly higher score on performance of physical activity (mean=2.68; SD=0.60) as compared to the girls (mean=2.38; SD=0.51) however it is still in the category of moderately active. Approximately 14.4% of children had a very low physical activity level. Conclusion: Overweight and obese boys had higher energy and fat intakes but were more physically active as compared to the girls. These findings might be useful in planning appropriate intervention strategies to be designed and delivered especially for this cohort.
Comparison of the regenerative effect of adipose‐derived stem cells, fibrin glue scaffold, and autologous bone graft in experimental mandibular defect in rabbit

BACKGROUND/AIMS One of the main concerns for maxillofacial and orthopedic surgeons is finding a method to improve regeneration of large craniofacial bone defects. The aim of this study was to investigate the healing and regenerative effects of fibrin glue associated with adipose-derived stem cells (ADSCs) and fibrin glue scaffold alone with autologous bone grafts in experimental mandibular defects of the rabbit. METHODS Bilateral uni-cortical osteotomies were performed in the mandible of 20 male Dutch rabbits. The animals were randomly divided into 2 equal groups. In one group, the defect on the right side was treated by fibrin glue associated with ADSCs and the defect on the other side remained as the control. In another group, the defect on the right side was treated with fibrin glue and on the left side with autologous bone graft. After 28 and 56 days, five rabbits from each group were evaluated by computed tomography (CT) and histopathological examinations. RESULTS Coronal CT showed a remarkable reconstruction of cortical bone in the fibrin glue associated with ADSCs group at 28 and 56 days post-surgery. Histopathologically, new cortical bony bridge formation was seen increasingly in the fibrin glue, fibrin glue associated with ADSCs, and autologous bone graft groups after 28 days. Statistical analysis of the thickness of new cortical bone in the treatment versus control groups showed a significant difference between fibrin glue alone and fibrin glue associated with ADSCs groups (P = 0.02). No significant difference was found between the fibrin glue associated with ADSCs and the autologous bone graft groups (P > 0.05). CONCLUSIONS The healing process had a significant increase in the thickness of new cortical bone when fibrin glue scaffold associated with ADSCs was used.
Content Validity of the Parentship Protocol: A Multidimensional Intervention for Parents of Adolescents with High-Functioning Autism Spectrum Disorder

Abstract The Parentship protocol is a short-term intervention program in occupational therapy for parents of adolescents with High-Functioning Autism Spectrum Disorder (HFASD). Its purpose is to promote parental resilience and enhance adolescents’ participation in daily life. Aims: To explore and analyze the perceptions of occupational therapists and parents of individuals with HFASD, regarding the content of the protocol and its theoretical framework. Methods: Implementation of a phenomenological qualitative approach using two focus groups (six occupational therapists and five parents). A transcript-based analysis was used for analyzing the data. Results: The degree of agreement regarding the potential purposes and contents of the protocol was high. In addition, nine themes were raised and led to changes and additions in the protocol. Conclusions: The study provided support for content validity and acceptability of the Parentship protocol. Future research should test the feasibility of this new intervention program.
Exploiting Spatio-Temporal Diversity for Water Saving in Geo-Distributed Data Centers

As the critical infrastructure for supporting Internet and cloud computing services, massive geo-distributed data centers are notorious for their huge electricity appetites and carbon footprints. Nonetheless, a lesser-known fact is that data centers are also “thirsty”: to operate data centers, millions of gallons of water are required for cooling and electricity production. The existing water-saving techniques primarily focus on improved “engineering” (e.g., upgrading to air economizer cooling, diverting recycled/sea water instead of potable water) and do not apply to all data centers due to high upfront capital costs and/or location restrictions. In this paper, we propose a software-based approach towards water conservation by exploiting the inherent spatio-temporal diversity of water efficiency across geo-distributed data centers. Specifically, we propose a batch job scheduling algorithm, called WACE (minimization of WAter, Carbon and Electricity cost), which dynamically adjusts geographic load balancing and resource provisioning to minimize the water consumption along with carbon emission and electricity cost while satisfying average delay performance requirement. WACE can be implemented online without foreseeing the far future information and yields a total cost (incorporating electricity cost, water consumption and carbon emission) that is provably close to the optimal algorithm with lookahead information. Finally, we validate WACE through a trace-based simulation study and show that WACE outperforms state-of-the-art benchmarks: $25$ percent water saving while incurring an acceptable delay increase. We also extend WACE to joint scheduling of batch workloads and delay-sensitive interactive workloads for further water footprint reduction in geo-distributed data centers.
Glide Symmetry to Prevent the Lowest Stopband of Printed Corrugated Transmission Lines

In this letter, we demonstrate that the dispersion properties of printed double-sided parallel-strip lines can be controlled by using glide symmetry. Glide symmetry is introduced in with corrugations in both strips of a double-sided line. We demonstrate that glide symmetry eliminates the stopband between first and second propagating modes and yields to a higher propagation constant, preserving its linearity, and the broadband nature of the underlying guiding technology. Thus, the glide-symmetric double-sided line can be designed to possess a high equivalent refractive index in an ultrawide range of frequencies. These exceptional properties have been numerically and experimentally validated. Finally, we demonstrate the possibilities of this technology with a specific design, a glide-symmetric double-sided parallel-strip line with filtering properties. Potential applications are low-dispersive leaky-wave antennas and electromechanical tunable phase shifters and filters.
Collegiate baseball players with more optimal functional movement patterns demonstrate better athletic performance in speed and agility

ABSTRACT Sports injuries are common among baseball players and may result in abnormal movement patterns, increased risks of future injury, and unsatisfactory performance. The Functional Movement Screen (FMS™) has been developed to detect abnormal functional movement patterns and can be used for predicting risks of sports injury. However, whether FMS™ scores are associated with athletic performance remains unclear. The goal of this study was to determine the association between functional movements and athletic performance in elite baseball players. Core stability, muscular strength and flexibility of the lower extremities, and FMS™, as well as athletic performance in sprinting, agility, and balance tests were assessed in 52 male collegiate Division I baseball players placed into two groups based on FMS™ scores. The high-scoring group demonstrated better athletic performance than the low-scoring group, with a shorter duration of the agility test. No group differences were found in core stability, muscular strength, or muscle flexibility, except for rectus femoris flexibility. Thus, the FMS™ score is associated with sprinting and agility performance in elite baseball players. These findings indicate that the FMS™ may have a role in predicting athletic performance and thereby help determine the goals of training regimens or return-to-play strategies.
Characterization and Compact Modeling of Nanometer CMOS Transistors at Deep-Cryogenic Temperatures

Cryogenic characterization and modeling of two nanometer bulk CMOS technologies (0.16- $\mu \text{m}$ and 40-nm) are presented in this paper. Several devices from both technologies were extensively characterized at temperatures of 4 K and below. Based on a detailed understanding of the device physics at deep-cryogenic temperatures, a compact model based on MOS11 and PSP was developed. In addition to reproducing the device dc characteristics, the accuracy and validity of the compact models are demonstrated by comparing time- and frequency-domain simulations of complex circuits, such as a ring oscillator and a low-noise amplifier, with the measurements at 4 K.
Experience Selection in Deep Reinforcement Learning for Control

Experience replay is a technique that allows off-policy reinforcement-learning methods to reuse past experiences. The stability and speed of convergence of reinforcement learning, as well as the eventual performance of the learned policy, are strongly dependent on the experiences being replayed. Which experiences are replayed depends on two important choices. The first is which and how many experiences to retain in the experience replay buffer. The second choice is how to sample the experiences that are to be replayed from that buffer. We propose new methods for the combined problem of experience retention and experience sampling. We refer to the combination as experience selection. We focus our investigation specifically on the control of physical systems, such as robots, where exploration is costly. To determine which experiences to keep and which to replay, we investigate different proxies for their immediate and long-term utility. These proxies include age, temporal difference error and the strength of the applied exploration noise. Since no currently available method works in all situations, we propose guidelines for using prior knowledge about the characteristics of the control problem at hand to choose the appropriate experience replay strategy.
On the Soundness and Security of Privacy-Preserving SVM for Outsourcing Data Classification

Recently, Rahulamathavan et al. propose a privacy preserving scheme for outsourcing SVM classification. Their core contribution is a secure protocol to attain the sign of numbers in encrypted form. In this paper, we observe that Rahulamathavan et al.'s protocol will suffer from some soundness and security problems. Then, we propose a new scheme to securely obtain the encrypted numbers’ sign. Theoretical analysis and experiment results show our proposed scheme can not only fix the soundness and security problems, but also achieve higher efficiency.
Equidistribution of divergent orbits and continued fraction expansion of rationals

We establish an equidistribution result for pushforwards of certain locally finite algebraic measures in the adelic extension of the space of lattices in the plane. As an application of our analysis, we obtain new results regarding the asymptotic normality of the continued fraction expansions of most rationals with a high denominator as well as an estimate on the length of their continued fraction expansions.
Factors Related to the Attitude of North Korean Refugees Towards People with Mental Illness

Background: The purpose of this study was to explore the level of mental health knowledge among North Korean refugees residing in South Korea and to analyze the factors related to their attitude towards people with mental disorders. Methods: The survey was conducted on 150 people and the analysis included results from 138 participants in 2013. A multiple linear regression analysis was conducted to analyze the factors related to the attitude towards people with mental illness. Results: The education level attained in South Korea and the duration of stay in the South were effective factors associated with anti-authoritarianism. Age, marital status, education level in the North, and level of mental health knowledge were significant factors for benevolence. Time spent in South Korea and knowledge of mental health played a significant role in determining their attitude towards social restrictiveness (P=0.014). Conclusion: The knowledge of mental illness in refugees was associated with their attitude towards people with mental illness. This study suggests the need to educate refugees on mental illness to enhance their attitudes.
Original and Repair Bulk Fracture Resistance of Particle Filler and Short Fiber-Reinforced Composites.

OBJECTIVE This study aimed to evaluate the original (OR) and repair (RR) fracture resistance of a semi-interpenetrating polymer network (semi-IPN)-based short fiber-reinforced composite compared to dimethacrylate-based composite materials by means of the V-notch test. METHODS AND MATERIALS Circular specimens (5×2 mm) with a centrally machined 90° V-shaped notch were prepared. Four bulk fill (Filtek Bulk Fill, Venus Bulk Fill, TetricEvo Ceram Bulk Fill, SDR), three microfilled hybrid (GC-Anterior, GC-Posterior, Z250), one nanofilled (SupremeXTE), and two short fiber-reinforced (Alert, everX Posterior) composites were selected. EverX Posterior was the semi-IPN material. Specimens (n=12/group) were either dry or water stored for 7 and 30 days, respectively, at 37°C and then loaded in two-point load until fracture. One-half of each tested specimen was used for the repair procedure. Repairing surfaces were diamond-bur ground, etched, and treated with silane containing universal adhesive (Scotchbond Universal) before repair. RESULTS Three-way analysis of variance revealed a significant statistical difference between the groups ( p<0.05). The fracture resistance of dry-stored groups was greater than that of water-stored groups. The highest OR was observed for dry-stored Alert (23.4 N/mm), which significantly deteriorated in water (17.4 N/mm) ( p<0.05). The highest RR was observed for everX Posterior (20.0 N/mm), which did not deteriorate in water significantly (19.0 N/mm) ( p>0.05). The everX Posterior preserved the specimens' integrity at the final fracture load (ductile fracture), whereas all other materials fractured into two halves at the interface (adhesive failure). CONCLUSIONS The only material that provided enhanced repair strength that was close to the original cohesive strength of the material was everX Posterior. The endurance of repaired restorations can be improved by using semi-IPN-based filling material.
Sleep Disturbances in COPD are Associated with Heterogeneity of Airway Obstruction

Abstract Individuals with Chronic Obstructive Pulmonary Disease (COPD) experience sleep disturbances due to the impact of respiratory symptoms on sleep quality. We explored whether sleep disturbances in COPD are linked to heterogeneity of airway constriction. The impact of breathing problems on sleep quality was measured in consecutive COPD outpatients with the COPD and Asthma Sleep Impact Scale (CASIS) questionnaire. Impulse oscillometry technique (IOS) was employed to assess heterogeneity of airway constriction. Subjects with a previous or concomitant diagnosis of asthma or obstructive sleep apnea (OSA) were excluded. Fifty COPD subjects (M/F 40/10; age: 71 ± 8 yrs, Body Mass Index (BMI): 26.2 ± 4.7 kg/m2, Forced Expiratory Volume in the first second (FEV1): 65 ± 25% predicted; mean ± SD) were enrolled. The mean CASIS score was 36 ± 3.3, and the R5–R20 value was 0.2 ± 0.15 kPa s L−1. The CASIS score was significantly higher in subjects with increased R5–R20 (>0.07 kPa s L−1) (39 ± 24; p = 0.02) compared to normal R5–R20 (21 ± 17). When subjects were categorized on the basis of lung function in severely versus non severely obstructed (FEV1 ≤ or >50% predicted) or air trappers versus non air trappers (Residual Volume, RV ≥ or <120% predicted) the CASIS score remained unchanged (for FEV1: 37 ± 23 versus 33 ± 25, respectively, p = 0.61; for RV: 30 ± 20 versus 40 ± 23, p = 0.16). Sleep disturbances due to COPD symptoms are associated with heterogeneity of airway constriction, possibly reflecting peripheral airway dysfunction.
Electromigration Reliability of Solder Balls

The electromigration performance of solder balls has been characterized in terms of its failure mechanism, process legs and current distribution. Through extensive failure analysis, a step-by-step mechanism of electromigration failure has been identified, which begins with the formation of CuSn at the expense of the under-bump metallurgy and nearby solder, followed by the nucleation and growth of voids along the CuSn-Sn interface until open circuit failure. Lifetime gains proportional to the thickness of the under-bump metallurgy and/or the redistribution layer have been measured. Finally, current distribution was observed to play a large role in EM lifetime, in which splitting the current equally between balls greatly outlived those configured serially.
