Behavior of parents and educators following traumatic injury to young permanent teeth of children in Joinville, Santa Catarina

Introduction: Traumatic dental injuries are a major public health problem, especially in the age range of 7 to 15 years, when young permanent teeth are established. Objective: To evaluate the behavior of parents of children who attend public or private school and their educators, in cases of traumatic injury to young permanent teeth and to evaluate whether they sought emergency guidance, in the city of Joinville, Santa Catarina, Brazil. Evaluation was carried out via a questionnaire for asking the parents and teachers about their knowledge of dental trauma. Material and methods: A total of 248 parents and 22 teachers participated in the study. Out of all the participants that completed the questionnaire with questions on previous trauma experience, avulsion behavior, avulsed tooth storage medium, and time elapsed from dental trauma until care, 49.6% of had higher education. The data were tabulated on a Microsoft Office Excel 365 worksheet, and the chi-square statistical test was applied. Results: The research showed that 91.8% of parents and 8.2% of educators from both public and private schools had minimal knowledge regarding dental trauma. Many of the participants (73.2%) were unaware of what dental reimplantation was and lacked knowledge regarding storage choices for a dental element. Instead, 68% preferred to take the child to a dental surgeon to receive emergency care. Conclusion: The knowledge parents and educators of public and private schools have about dental trauma is limited. Education on this subject needs to be promoted for enabling parents and educators to make informed decisions to ensure the best prognosis after traumatic dental injury.
How Does the Spillover among Natural Gas, Crude Oil, and Electricity Utility Stocks Change over Time? Evidence from North America and Europe

Our study analyzes the return and volatility spillover among the natural gas, crude oil, and electricity utility stock indices in North America and Europe from 4 August 2009 to 16 August 2019. First, in time domain, both total return and volatility spillover are stronger in Europe than in North America. Furthermore, compared to natural gas, crude oil has a greater volatility spillover on the electricity utility stock indices in North America and Europe. Second, in frequency domain, most of the return spillover occurs in the short-term, while most of the volatility spillover occurs over a longer period. Third, the rolling analyses indicate that the return and volatility from 2009 to late 2013 remained stable in North America and Europe, which may be a result of the 2008 global financial crisis, and started to fluctuate after late 2013 due to some extreme events, indicating that extreme events can significantly influence spillover effects. Moreover, investors should monitor current events to diversify their portfolios properly and hedge their risks.
Downregulation of ZFX is associated with inhibition of prostate cancer progression by baicalein

Background: Baicalein is a bioactive flavonoid that is widely used in China. However, its effects on prostate cancer (PCa) and relative mechanisms have not been extensively studied. We intended to study the potential anti-tumor effects of baicalein and the related mechanisms on PCa. Methods: We analyzed the inhibitory effects of baicalein on PCa by utilizing a cell viability assay and an in vivo tumor growth assay. Wound healing assay and transwell assay were performed to investigate cancer cell migration and invasion abilities. Then the expressions of zinc finger protein X-linked (ZFX) in PCa cells and xenograft tumor were respectively detected by western blot and immunohistochemistry assay. Results: Baicalein significantly inhibited cell proliferation in vitro and tumor growth of PCa in vivo. Consistently, baicalein induced significantly inhibition on the migration and invasion abilities of PCa cells. In addition, ZFX expressions were downregulated by baicalein in PCa both in vitro and in vivo. Conclusions: Our study provides evidence that baicalein plays important roles in PCa therapy probably by downregulating ZFX expression, which was demonstrated to be involved in PCa progression, and thus may be developed as a novel and efficient candidate agent for PCa therapy.
Catching flying fish (Hirundichthys oxycephalus) in the central Makassar Strait fishing ground using drifting gillnet

Catching flying fish (Hirundichthys oxycephalus) in the central of Makassar Strait using drifting gillnet with a mesh size of 2.54 and 3.18 cm was carried out in west and east season. Drifting gillnets with mesh size of 2.54 cm and 3.18 cm caught H. oxycephalus with a number of catches that varied every month throughout the season. The objective of this study was to compare CPUE rates of two different mesh size of gillnet and to describe the sea surface temperature conditions at the fishing ground locations. We conducted this research during east season (April-June). The study used satellite SST data combined with experimental fishing by operating one experimental unit of drifting gillnets with mesh size of 2.54 cm and 3.18 cm in the fishing area for 30 fishing trips. CPUE (kg hauling−1) was the amount of catch per hauling. The difference in catch between the mesh size of 2.54 and 3.18 cm was assessed by t-test analysis using SPSS software package. The results showed that CPUEs per piece of gillnets with the mesh size of 2.54 cm were ranged from 0.23 to 2.90 kg hauling−1 with 1.38 kg hauling−1 on average, while the CPUEs for the mesh size of 3.18 cm were ranged from 0.47 to 8.93 kg, with 3.28 kg hauling−1 on average. The t-test showed that mesh size of 3.18 cm was significantly different from the mesh size of 2.54 cm. CPUE of drifting gillnets with the mesh size of 3.18 cm higher than the mesh size of 2.54 cm and occupied the potential fishing grounds with relatively warmer SST of 29-31°C. This suggests that the gillnet mesh size of 3.18 cm is better than the other size for catching flying fish within the potential fishing grounds during April-June.
A combined reinforcement learning and sliding mode control scheme for grid integration of a PV System

The paper presents development of a reinforcement learning (RL) and sliding mode control (SMC) algorithm for a 3-phase PV system integrated to a grid. The PV system is integrated to grid through a voltage source inverter (VSI), in which PV-VSI combination supplies active power and compensates reactive power of the local non-linear load connected to the point of common coupling (PCC). For extraction of maximum power from the PV panel, we develop a RL based maximum power point tracking (MPPT) algorithm. The instantaneous power theory (IPT) is adopted for generation reference inverter current (RIC). An SMC algorithm has been developed for injecting current to the local non-linear load at a reference value. The RL-SMC scheme is implemented in both simulation using MATLAB/SIMULINK software and on a prototype PV experimental. The performance of the proposed RL-SMC scheme is compared with that of fuzzy logic-sliding mode control (FL-SMC) and incremental conductance-sliding mode control (IC-SMC) algorithms. From the obtained results, it is observed that the proposed RL-SMC scheme provides better maximum power extraction and active power control than the FL-SMC and IC-SMC schemes.
Readiness of Enterprises in Czech Republic to Implement Industry 4.0: Index of Industry 4.0

Industry 4.0 includes digital process transformation, information technology (IT) development, mobile devices, learning software, automation, and robotics, as well as intelligent sensors to collect large datasets, store, analyze, and use them in business, including simulation, virtual reality, and digital twins. The aim of the paper is to characterize the readiness of the enterprise to use Industry 4.0. In the research, a questionnaire survey was carried out on a sample of 276 enterprises mainly from the manufacturing industry. Using explorative factor analysis, the index of Industry 4.0 (VPi4) was designed to determine the level of Industry 4.0 implementation in the enterprises. The results were further verified by a statistical analysis, using Mann–Whitney test and correlation coefficients. The results indicate that the VPi4 index was consistent in terms of distribution when comparing the results on the verification sample. Its results correlate with the subjective perception of the enterprises, and different levels of the index reflect the difference in technological intensity of the industry. The VPi4 index enables the enterprises to determine their own level of current state of readiness for Industry 4.0, to better prioritize business development. The proposed solution categorizes Industry 4.0 components into a useful theoretical framework. Further research offers the possibility of applying the index in other sectors, its relation to the size of enterprises, and updating with respect to new trends in information technology.

Understanding the Gender Gap Further: The Case of Turn-of-the-Century Swedish Compositors

To better understand the historical gender wage gap, we investigate the wages of Swedish compositors circa 1900 using a rich data set of matched employer-employee information with national coverage. In line with previous findings, women earned about 70 percent of men’s wages on average. Individual and job characteristics explain much of this shortfall. Firm characteristics or firm fixed effects, on average, explain 17 percent of the gap, though the firm mattered more for the gender gap in big cities than elsewhere. Sorting across firms is thus an important part of understanding historical gender wage gaps. While most studies conclude that a significant portion of the gender gap is unexplained, suggesting labor market discrimination, this may result from a lack of information on the distribution of men and women across firms.
Study prevalence of peripheral arterial disease in diabetics with coronary artery disease at a large tertiary care teaching hospital in North India

Background: Peripheral arterial disease and coronary artery disease have similar factors. The extent and severity of PAD is significantly associated with presence and severity of CAD. Methods: Patients were interviewed and clinical profile of patients including risk factors of coronary artery disease like diabetes, hypertension, smoking, dyslipidemia, obesity and family history of coronary artery disease were assessed and recorded in the proforma. Information regarding demographics, co morbidity, past history and family history was collected. Physical examination of each patient was carried and basic anthropometric data: height, weight, BMI and blood pressure, peripheral pulses calculated. Investigations both noninvasive and invasive including peripheral angiography were recorded. Results: In this prospective study fifty (50) type 2 diabetes patients admitted with CAD were studied whose mean age was 55.6+8.2 and mean duration of diabetes was 6.8+8.4. In this study none of the patients with PAD had single atherosclerosis risk factors including diabetes. 30% patients were having two risk factors. PAD in in patients with CAD is particularly enhanced by the concomitant occurrence of two or more of these risk factors (p=0.016). Hypertension as a predictor of PAD was statistically significant (p=0.0037). In this study the duration of diabetes was <5 years in 10%, 5-10 years in 40% and >10 years in 40% of patients with angiographically proven PAD. Conclusions: It was observed that presence and severity CAD was significantly associated with PAD.
Radiographic analysis and performance of coffee seeds

Abstract: Radiographic analysis has been efficient in identifying the main changes in the internal morphology of seeds, being increasingly used in quality control programs due to their practicality, objectivity and speed in obtaining the results. Despite these advantages, there are still no studies proving the efficiency of these techniques for coffee seed analysis. Thereby, the aim of this research was to evaluate the internal morphology of coffee seeds (Coffea arabicaL.) through the analysis of radiographic images and their relation with germination performance. Radiographic images of seeds of the cultivars Bourbon and Catucaí 20/15, each represented by six lots, were examined and the seeds were seeded and seedling emergence, shoot length, stem diameter and shoot dry mass were evaluated. Seeds of Bourbon presented high percentage of intact seeds, as well as better performance in the germination of the lots compared to Catucaí 20/15, which presented more incidence of damaged seeds and lower germination. The radiographic images allowed identifying seeds with malformations, tissue deterioration and damage caused by the coffee borer. This non-destructive imaging technique is efficient in identifying intact seeds, with potential to germinate and produce vigorus seedlings.
Using Approximate Computing and Selective Hardening for the Reduction of Overheads in the Design of Radiation-Induced Fault-Tolerant Systems

Fault mitigation techniques based on pure software, known as software-implemented hardware fault tolerance (SIHFT), are very attractive for use in COTS (commercial off-the-shelf) microprocessors because they do not require physical modification of the system. However, these techniques cause software overheads that may affect the efficiency and costs of the overall system. This paper presents a design method of radiation-induced fault-tolerant microprocessor-based systems with lower execution time overheads. For this purpose, approximate computing and selective fault mitigation software-based techniques are used; thus it can be used in COTS devices. The proposal is validated through a case study for the TI MSP430 microcontroller. Results show that the designer can choose among a wide spectrum of design configurations, exploring different trade-offs between reliability, performance, and accuracy of results.
Attitude of Tuberculosis Patients Towards the Risk of HIV/AIDS

Abstract Tuberculosis patients are more likely to test positive to Human Immunodeficiency Virus and this is the reason more TB patients need to be tested for HIV. The goal of this paper was to find out the attitude of TB patient towards the risk of HIV/AIDS. Descriptive survey design was used with 150 participants who are receiving treatments at Directly Observed Therapy (DOT) centers in Ibadan metropolis. The survey used a pre-coded, selfadministered questionnaire, which contained approximately 53 items, including demographic information. The results show that TB patients have negative attitude towards HIV as a result of fear of double stigmatization. Based on this finding, it was recommended that the healthcare system should be strengthened by embarking on periodical enlightenment programs that create awareness about danger of stigmatization of TB patients. This will help in removing the barrier of stigmatization towards tuberculosis patients for better combat HIV/AIDS.

Sosiodemografi factors such as age, occupation, parity and status women aff ect the injection contraceptive acceptors did not choose long acting contraception method in Tambaksari Surabaya Gading Public Health Center. The granting of complete information about all types of contraception is important so that the fertile age couples can choose contraception that suits their need.
Multidimensional Spectroscopy of Mixed-Cation Perovskite Thin Films

Metal halide perovskite (MHP) thin films are currently undergoing an intense research thrust due to the excellent performance of MHP based photovoltaic (PV) devices, which have the potential to revolutionize the worlds energy production via a unique combination of low-cost fabrication and high power conversion efficiency (PCE). However, the vast majority of research is currently aimed at incremental improvements in device PCE, resulting in a body of work without the foundational understanding of the charge-carrier dynamics of the system upon photoexcitation. This thesis begins with the development of a phase-modulated multidimensional coherent spectroscopy (PM-MDCS) experiment. PM-MDCS is an ultrafast multidimensional coherent spectroscopy (MDCS) technique that can identify photophysical processes unavailable to one-dimensional spectroscopies. The thesis then goes on to describe the development of a novel data acquisition scheme and data processing technique, diagonal slice four-wave mixing (DS-FWM). Next, a description of calibrating the absolute phase in PM-MDCS experiments is presented. Finally, the thesis discusses the application of steady-state photoluminescence (PL), MDCS, and DS-FWM to study the charge-carrier dynamics in MHP thin films at 5K. These studies provide crucial information to building a fundamental understanding of the photophysical processes in MHP films under illumination, providing direction for targeted research toward improved MHP PV performance.
Application of Clean and Healthy Living Behavior (PHBS) From The Household Knowledge and Attitude Study

Background: The behavior of clean and healthy life (PHBS) is an obligation to be carried out by everyone. PHBS is an effort to maintain the health of themselves and their families. The PHBS coaching program has been running for approximately 18 years, but its success is far from expected. It is necessary to explore the factors underlying the failure to implement PHBS. Mothers as educators in the family, have an obligation not only to implement PHBS for themselves, but also educate their children to conduct clean and healthy lifestyle.Purpose: The purpose of this study was to determine the application of clean and healthy behavior (PHBS) from the study of knowledge and attitudes of housewives in the household setting.Method: This research is a descriptive study with a cross sectional approach, involving 39 housewives in RT 03 RW 06 Tlogomas Malang. The sample is taken in total side. The independent variable is the knowledge and attitudes of housewives, while the dependent variable is clean and healthy living behavior. Instrument to explore knowledge, attitudes and behavior using a questionnaire. Data analysis using the Spearman rank test.Result: The results showed that as many as 43.6% of housewives were well informed, 76.9% of housewives had good attitudes, and as many as 69.2% of mothers had good PHBS. Statistical tests show there is no relationship between knowledge with PHBS (p value 0.792), and there is a relationship between attitudes and PHBS of housewives (p-value 0.007). Conclusion: The application of clean and healthy lifestyle is not related to knowledge, but is related to the attitude of housewives in RT 03 RW 06 Tlogomas Malang.
Optimizing the use of capsule endoscopy in the detection of small-bowel pathology

Background Wireless capsule endoscopy (CE) was introduced in clinical practice just over a decade ago; it has since established a new era in the investigation and diagnosis of small-bowel diseases. Nevertheless, the detection of small-bowel pathology can be limited by issues related to the current level of CE technology. Furthermore, the clinical validity of the use of surrogate markers of diagnostic yield such as the ampulla of Vater (AoV), or that of various prokinetics, to increase the completion rate and theoretically, the diagnostic yield have not been clearly established. Other factors that could optimize the rate of detection of small-bowel pathology in CE are: 'speedy' video sequence review, chromoendoscopy and/or the application of three-dimensional (3-D) image-reproduction software. Threedimensional imaging in CE is not currently feasible due to hardware limitations. However, software algorithms (shape-from-shading, SfS) that enable 3-D reconstruction in CE are available. Methods The database of capsule endoscopy examinations of our centre includes procedures performed with two different models of capsule endoscopes. The detection rate of the duodenal papilla was examined in the largest to date cohort of small-bowel capsule endoscopy videos obtained with two different capsule endoscopy systems. Using meta-analysis software, the impact of various prokinetics was analysed. Furthermore, the validity and safety of QuickView pre-read was examined. In regard to proprietary chromoendoscopy software, Blue Mode filter offers better image enhancement when compared with Fujinon Intelligent Chromoendoscopy (FICE). Out of four publicly available SfS algorithms, Tsai's method is the one that gives the better results. Tested on still-capsule endoscopy images, the application of a 3-D reconstruction software leads to image enhancement for a significant proportion of
