Authors: Ahmed Abdulatif Hajjismael , Hamed Osman Alfahim Osman , Gocheva Svetla 
Published: October 2020

AbstractConflict is a part of daily life and it can occur for many reasons. In an intercultural environment, both international and local people can face conflict due to their interactions. Even though there has been an exponential increase in the growth of international students in Turkey in recent years, little is known about their experiences in the realm of intercultural conflicts. Therefore, the main objective of this study was to assess the occurrence of intercultural conflicts among international students at Anadolu University. In particular, the study sought to examine possible intercultural conflicts this group of students might experience, international students’ intercultural awareness, the major sources of the intercultural conflict and how the international students cope with intercultural conflict. A qualitative research method with phenomenological research design was utilized and semi-structured in-depth interviews were used to gather data. The analysis of the study was organized into six themes, namely: awareness, approach, experience, communication style, worldview change, and coping strategy. Except for the last theme, the obtained data aligned with the literature. Findings revealed that the international students experienced intercultural conflicts mainly due to lack of intercultural competence. Based on these findings, recommendations for future studies were suggested.

Authors: Dirik Fadime , Demirci Kamil , Yıldız Sevda , Acu Ana Maria 
Published: October 2020

Abstract
In this paper, we introduce an interesting kind of convergence for a double sequence called the uniform convergence at a point.
We give an example and demonstrate a Korovkin-type approximation theorem for a double sequence of functions using the uniform convergence at a point.
Then we show that our result is stronger than the Korovkin theorem given by Volkov and present several graphs.
Finally, in the last section, we compute the rate of convergence.

Abstract

Objectives
Breast cancer is known as one of the deadliest forms of cancer, and it is increasing globally. There are a variety of proven and controversial risk factors for this malignancy. Herein, we aimed to undertake a systematic review and meta-analysis focus on the epidemiology of breast cancer risk factors in Iran.

Methods
We performed a systematic search via PubMed, Scopus, Web of Science, and Persian databases for identifying studies published on breast cancer risk factors up to March 2019. Meta-analyses were done for risk factors reported in more than one study. We calculated odds ratios (ORs) with corresponding 95% confidence intervals (CIs) using a fixed/random-effects models.

Results
Thirty-nine studies entered into the meta-analysis. Pooling of ORs showed a significant harmful effect for risk factors including family history (OR: 1.80, 95%CI 1.47–2.12), hormonal replacement therapy (HRT) (OR: 5.48, 95%CI 0.84–1.74), passive smokers (OR: 1.68, 95%CI 1.34–2.03), full-term pregnancy at age 30 (OR: 3.41, 95%CI 1.19–5.63), abortion (OR: 1.84, 95%CI 1.35–2.33), sweets consumption (OR: 1.71, 95%CI 1.32–2.11) and genotype Arg/Arg (crude OR: 1.59, 95%CI 1.07–2.10), whereas a significant protective effect for late menarche (OR: 0.58, 95%CI 0.32–0.83), nulliparity (OR: 0.68, 95%CI 0.39–0.96), 13–24 months of breastfeeding (OR: 0.68, 95%CI 0.46–0.90), daily exercise (OR: 0.59, 95%CI 0.44–0.73) and vegetable consumption (crude OR: 0.28, 95%CI 0.10–0.46).

Conclusions
This study suggests that factors such as family history, HRT, passive smokers, late full-term pregnancy, abortion, sweets consumption and genotype Arg/Arg might increase risk of breast cancer development, whereas late menarche, nulliparity, 13–24 months breastfeeding, daily exercise and vegetable consumption had an inverse association with breast cancer development.
Identifying challenges in promoting adolescent preventive health care in the primary care setting of urban Japan
Authors: Sakashita Kazumi , Blum Robert W. 
Published: October 2020

Abstract

Background
Despite the assurance of free medical access through the universal health insurance system, over the past three decades Japanese youth have experienced an increase in developmental and behavioral problems, psychosomatic disorders, and psychiatric illnesses.

Objectives
To identify the challenges in promoting comprehensive preventive health services to adolescents in Japan, specifically in Tokyo.

Methods
A cross-sectional online survey was conducted of physicians who are members of the Tokyo Pediatric Association. The questionnaire assessed primary care pediatricians’ practice settings and their attitudes toward outpatient services to adolescent patients.

Results
Out of 617 member pediatricians, 69 valid responses were obtained. Majority were private pediatricians. 52% indicated that they had specialties in addition to general pediatrics; however, no one reported specializing in adolescent medicine. Approximately 70% answered the optimal patient encounter time would be under 10 min. More than 90% of respondents reported challenges providing health services to adolescent patients. Nearly half indicated that they did not routinely evaluate height, heart rate or blood pressure. Few providers asked about reproductive health, violence, or smoking/alcohol use.

Conclusion
This survey is the first exploration of adolescent health care in an urban area of Japan. While the sample is small, the magnitude of challenges was great with limited training in adolescent medicine, severe time constraints and limited appreciation for the value of health screening at each encounter. Developing a standardized practical assessment tool for adolescent patients may help guide primary care pediatricians to better meet the needs of their adolescent patients.

Published: October 2020

Abstract

Background
Associations between mental health and dermatology have generated a new branch of study called psychodermatology, which includes relevant conditions to the adolescent population. However, there is limited research focusing on this field and this specific population.

Objective
To estimate the prevalence of dermatological pathologies in the Colombian adolescent population and their possible associations with mental health conditions.

Methods
We performed a secondary analysis of the Colombian National Mental Health Survey results. A representative sample of the adolescent Colombian population answered questions regarding dermatological conditions and mental health disorders. We estimated the prevalence and evaluated associations using the chi squared independence test.

Results
Of 1753 adolescents, 8.3% (CI95%=[6.8–10.1]) had dermatitis or skin allergies and 4.5% (CI95%=[3.3–6.1]) acne. For dermatitis, we found associations with age, education, and family dysfunction (p-Values=0.024; <0.001; 0.046 respectively). Acne was associated with age, sex, educational level, the number of social groups involved in, alcohol consumption, psychoactive substances use and previous violent experiences (respective p-Values=0.007; 0.004; 0.005; 0.036; 0.002; 0.003; 0.044). Regarding mental health, dermatological conditions were associated with depression, affective disorders, suicide attempt and suicide ideation.

Conclusion
Our results are the first to describe the prevalence of these disorders in Colombia. This is an exploratory study; nonetheless, it is of great value since it is the first to describe these associations in adolescents in a middle-income country, which should be considered during clinical examinations. Further longitudinal studies evaluating possible causal relationship between psychiatric and dermatological conditions are fundamental to establish causal links.

Published: October 2020

AbstractIn the present study, the production process of zinc sulfate from the zinc oxide ore was experimentally investigated. The effect of main operating condition such as weight ratio of sulfuric acid to zinc content of ore (H2SO4/zinc), leaching temperature (°C), stirring speed (rpm), leaching time (min), particle size (mm), solid to liquid ratio (pulp density, wt. %), additives amount (kg/m3) and leaching pH on dissolution process of zinc oxide ore in H2SO4solution were evaluated. Taguchi method and Aspen Plus software were used to determine the optimum condition and simulate the production process of zinc sulfate. Also, Aspen Plus software was used to determine the efficiency of zinc sulfate production. The experimental factors and their levels were as follows: 0.937–1.875 for the weight ratio of sulfuric acid to zinc content of ore, 50–80 °C for the leaching temperature, 100–400 rpm for stirring speed, 30–120 min for leaching time, 0.01–10 mm for particle size, 10–40 wt% for pulp density, 10–50 kg/m3for additives amount and 1.4–2 for solution pH. The optimum condition was found to be H2SO4/Zinc ratio, 1.25; temperature, 70 °C; agitation rate, 200 rpm; leaching time, 30 min; particle size, 1 mm; pulp density, 10 wt%; additives amount, 30 kg/m3and pH, 1.8. The most effective factors for maximizing the dissolution of ZnO in H2SO4was the leaching pH. The predicted results by Aspen Plus simulation indicated that the total efficiency of zinc recovery at optimum condition is more than 97%.

Published: October 2020

AbstractTo reveal the catalytic potential of abandoned naturally occurring material, we synthesized titania-termite hill composite (Ti-THC) via an incipient wetness impregnation route, characterized by various techniques and tested as a catalyst for transesterification of waste frying oil (WFO). The reusability of the prepared catalyst was also studied to evaluate its stability. The effects of reaction process parameters, such as temperature, time, catalyst loading and methanol/WFO molar ratio on fatty acid methyl ester (FAME) yield, were investigated using a central composite design approach. SEM result revealed pores formation on the catalyst surface, while XRD and EDX analyses confirmed successful insertion of titania into the aluminosilicate layer of the termite hill. The maximum FAME yield of 90.78% was obtained at optimum experimental conditions of 71.16 °C reaction temperature, 2.12 h reaction time, 1.03 wt.% catalyst loading and 9.96:1 methanol/WFO molar ratio. The catalyst still maintained its better stability after being reused for three reaction cycles.

Authors: Jiang Yang , Du Jinhua , Zhang Liguo 
Published: October 2020

Abstract
To comparatively investigate the applications potential of pectin from steeped hawthorn wine pomace (SHP), pectin-enriched yogurt was produced at set/stirred form using apple-sourced commercial pectin (CP) as control. The focus was mainly on the effect of pectins on the texture and stability of yogurt, as well as the analysis of appearance and taste, which were mainly characterized by texture analysis and sensory evaluation. Texture analysis indicated that the performance of SHP was better than that of CP, which could increase the gel rupture strength and rupture distance of set yogurt. SHP could also improve the firmness, denseness and viscosity of stirred yogurt. In other respects, SHP could also significantly increase the water holding capacity and sensory acceptance of both types of yogurt. The utilization of SHP for improving the quality of yogurt demonstrated its great potential in developing the sustainable applications of the by-product from steeped hawthorn wine.

Published: October 2020

Abstract
The purpose of this study was to improve the processability of rice powder using fluidised-bed granulation technology. Bukkyungmi-rice granules were prepared by fluidised-bed granulation for 1 and 2 h using water, 5% lactose (w/v) and 5% dextrin (w/v) solutions as dispersants. The particle size of Bukkyungmi-rice granules increased from 574.83 to 728.07 μm. Granules were produced due to pore formation, and the produced particles could be dispersed easily without any entanglement. The water solubility of the produced rice granules is 1.91–6.74%, which reflects the improvement in their quality with increased treatment time. In particular, Bukkyungmi-rice granules processed in 5% dextrin showed excellent settleability. The enthalpy (ΔH) was found to be the highest for Bukkyungmi-rice granules processed in 5% dextrin for 2 h by differential scanning calorimetry. The results indicated that rice granules obtained by fluidised-bed granulation could be used in various types of rice-based foods.

Published: October 2020

Abstract
Yogurt production with starter culture at 41 °C in the presence of plant water extracts (Momordica grosvenori, Psidium guajava, Lycium barbarum or Garcinia mangostana) were studied to examine the effects on acidification, physicochemical properties, microbial growth, proteolytic activity, and exopolysaccharide (EPS) content. All plant-based yogurt reached a pH of 4.5 faster (300–330 min) than plain-yogurt (360 min). All plant water extracts stimulated Lactobacillus spp. (∼7.4 log10 CFU/mL) and Streptococcus thermophilus (8.20–8.50 log10 CFU/mL) growth except for G. mangostana which marginally inhibited Lactobacillus spp. growth (7.21 log10 CFU/mL). M. grosvenori, L. barbarum, and G. mangonstana were significantly affected proteolysis of milk proteins (46.2 ± 0.8, 39.9 ± 0.5, & 35.8 ± 0.1 µg/mL; respectively) compared to plain-yogurt (26.3 ± 0.4 µg/mL). The presence of G. mangostana and L. barbarum resulted in an increase (p < 0.05) of total solids content (∼15.0%) and water holding capacity in yogurt (28.1 ± 1.2 & 26.5 ± 0.3%; respectively; p < 0.05). In addition, M. grosvenori water extract enhanced (p < 0.05) syneresis of yogurt (1.78 ± 0.30%). L. barbarum yogurt showed the highest EPS concentration (220.9 ± 12.4 µg/L) among yogurt samples. In conclusion, the presence of plant water extracts positively altered yogurt fermentation, enhanced proteolysis of milk protein, and induced EPS production.

Published: October 2020

Abstract
Mixtures of water and ethanol were tested for the extraction of betacyanins from Hylocereus polyrhizus peel to obtain natural colorants. In order to obtain betacyanins in a purified form, adsorption was carried out with two types of multi-walled carbon nanotubes (MWCNTs; pristine MWCNTs and carboxylated MWCNTs) and two macroporous resins (X-5 and AB-8). Carboxylated MWCNTs showed the highest adsorption capacity. On the basis of static adsorption test, carboxylated MWCNTs were selected for kinetic and isotherm studies. Langmuir and pseudo-first-order models could describe the process well. According to the Langmuir model, the maximum monolayer adsorption amount of carboxylated MWCNTs was 84.6 mg/g. After purification on a chromatographic column packed with carboxylated MWCNTs, the content of H. polyrhizus peel betacyanins in the pigment product was 4.62%.
Bifurcation, routes to chaos, and synchronized chaos of electromagnetic valve train in camless engines
Authors: Chang Shun-Chang 
Published: October 2020

Abstract
The main objects of this paper focus on the complex dynamics and chaos control of an electromagnetic valve train (EMV). A variety of periodic solutions and nonlinear phenomena can be expressed using various numerical techniques such as time responses, phase portraits, Poincaré maps, and frequency spectra. The effects of varying the system parameters can be observed in the bifurcation diagram. It shows that this system can undergo a cascade of period-doubling bifurcations prior to the onset of chaos. Lyapunov exponents and Lyapunov dimensions are employed to confirm chaotic behavior for EMV. A proposed continuous feedback control method based on synchronization characteristics eliminated chaotic oscillations. Numerical simulations are utilized to verify the feasibility and efficiency of the proposed control technique. Finally, some robustness analysis of parametric perturbation on EMV system with synchronization control is confirmed by Lyapunov stability theory and numerical simulations.

Authors: Ali Faisal , Aslam Waqas , Huang Shuliang 
Published: October 2020

Abstract
Most of the problems in mathematical and engineering sciences can be studied in the context of nonlinear equations. In this paper, we develop a new family of iterative methods for the approximation of the zeros of mathematical models whose governing equations are nonlinear in nature. The proposed methods are based on decomposition technique due to Daftardar-Gejji and Jaffri [1]. The new family gives several iterative schemes as special cases. The convergence analysis of proposed methods is also presented. In order to determine the performance of newly developed methods, numerical as well as graphical analysis of four complex mathematical models from diverse fields of science and engineering are considered. We also consider some complex polynomials to visualize the roots through polynomiography in the context of proposed methods.

AbstractIn this paper, we test to what extent Food Quality Schemes (FQS, including Geographical Indications and organic products) contribute to the social and economic sustainability of farmers and regions through employment and education. Through employment, FQS may counter the urban migration trend affecting rural regions, and help retain economic and social capital in the local region. Indeed, as FQS are often small and specialised sectors, the economic inefficiency of such businesses may translated into greater employment and social sustainability. Separately, by requiring a higher-level of quality and hence skills, FQS may encourage greater local educational attainment or skilled immigration. To test these propositions, we analyse the employment and educational outcomes of 25 FQS. Our results show that the FQS products examined have a 13% higher labour usage (labour-to-production ratio) compared to reference products, indicating that they provide greater employment. Additionally, wage levels are 32% higher in FQS compared to references. Despite providing greater employment and higher wages, profitability of FQS (i.e. how much turnover/profit is generated per employee) is nevertheless 32% higher for FQS compared to reference products, due to the ability to attract higher product prices. Finally, there is no clear link between FQS and greater (or lower) education attainment in the supply chain. Overall, our results suggest that FQS can provide a strong contribution to local employment, employee income and business profits, strengthening the social and economic sustainability of producers and regions.
Prediction of RTK positioning integrity for journey planning
Authors: El-Mowafy A. , Kubo N. 
Published: October 2020

Abstract
Positioning integrity is crucial for Intelligent Transport Systems (ITS) applications. In this article, a method is presented for prediction of GNSS positioning integrity for ITS journey planning. This information, in addition to other route information, such as distance and time, can be utilized to choose the safest and economical route. We propose to combine the Advanced Receiver Autonomous Integrity Monitoring (ARAIM) technique, tailored for ITS, with 3D city models. Positioning is performed by GNSS Real-Time Kinematic (RTK) method, which can provide the accuracy required for ITS. A new threat model employed for computation of the protection levels (PLs) for RTK positioning is discussed. Demonstration of the proposed approach is performed through a kinematic test in an urban area in Tokyo. The comparison between the prediction method and the actual observations show that the two estimate close satellite geometry and PLs. The method produced PLs that bounds the actual position errors all the time and they were less than the preset alert limit.
