Introduction: Obesity has significant physical and psychological implications along with severe impacts on social and interpersonal relationships of individuals. The present work is a comparative study between normal weight, overweight and obese individuals with respect to their personality traits and attachment in romantic relationships, it also aims to explore the relationship of body mass index with the variables chosen.

Material And Method: The total sample size was 90. The study was conducted upon three groups-the three groups consisted of 30 normal weight participants, 30 overweight participants and 30 obese participants each. Participants were grouped on the basis of their Body Mass Index (BMI)- which was calculated from self-reported measures of height and weight. All participants were administered the NEO-Five Factor Inventory and the Experiences in Close Relationships- Revised Questionnaire. On the basis of the obtained data, an Independent Samples t-test was done to see if there existed any significant difference between the groups. A Pearson’s coefficient correlation was performed for the total sample and a Stepwise multiple regression analysis was performed to see if any of the variables were significant predictors of BMI for the present sample.

Results: Significant differences existed between the groups in case of neuroticism, extraversion, openness and conscientiousness. The BMI of adults in the present sample has a significant positive correlation with openness and anxious attachment in romantic relationships and a significant negative correlation with extraversion and conscientiousness. Openness and conscientiousness were also significant predictors of BMI for the present sample.

Theology of the family in the final documents of the General Latin American Episcopal Conferences
Authors: Hajduk Ryszard
Published: October 2021

The final documents from the General Conferences of the Latin American Bishops (CELAM) held in Medellín (1968), Pueblo (1979), Santo Domingo (1992) and in Aparecida (2007) present the fruits of reflecting on the situation of the family in South America, Central America and the Caribbean, as well as its role in the Church and its importance in shaping social life. Consequently, one can speak of a Latin American theology of the family, which draws its impetus from the teaching of the universal Church, and at the same time has specific features. It is distinguished by the emphasis placed on the subjectivity of families in the saving mission of the Church and treating them as a “theological key”, opening the way to getting to know God's mysteries. It is a practice-oriented theology that gives concrete guidelines to families and their pastors. The character of Latin American theology of the family is influenced by the pastoral context and theological trends, born in South and Central America (liberation theology, indigenous theology and theology of the people). Latin American theology of the family is therefore not a repetition of the contents of the Magisterium of the universal Church, but their original interpretation, taking into account the social situation and the needs of people living in it.
La “ecología” en el pensamiento de los Padres de la Iglesia
Authors: Raczkiewicz Marek
Published: October 2021

Hablar de la “ecología” en los Padres de la Iglesia es hablar de la teología de la creación. En el siglo II, la Iglesia tuvo que enfrentarse a las corrientes, internas y externas, que veían el origen del mal en lo creado, en la materia, en el cuerpo. Son obras de un demiurgo imperfecto identificado con el Dios del Antiguo Testamento. Los autores cristianos como Ireneo argumentan que todo lo creado viene y es querido libremente por Dios. Las tres Personas de la Trinidad dejaron su impronta en la creación. Pero la vocación de la creación no consiste en jugar un papel pasivo, pues participa activamente en la historia de la salvación. El pan y el vino, las primicias de la creación, se convierten en el Cuerpo y la Sangre de Jesucristo. El cristiano, por tanto, debe cuidar de la creación que le habla del dinamismo trinitario, anima a aspirar a la santidad y comparte con él el camino a la salvación.

This paper considers theoretical and practical approaches to the construction of amplitude-frequency phase characteristics of turbofan engines and presents the results of the experiments. The novelty lies in excluding usage of information from the sensor of its initial position for the construction of the rotor phase characteristic. To determine the instantaneous value of the phase angle of the rotor oscillations, the method of orbital vibration analysis is used. Using the analysis of phase change of rotor fluctuation allows to define availability of resonance as well as defects and malfunctions that cause induce stiffness and damping of the rotor. Examples of turbofan engines diagnostics by means of the analysis of amplitude-frequency phase characteristics are given.

Published: October 2021

Experimental dependences U (t) of electric voltage on time t, taken from an induction magnetic head (MG), moving relative to a magnetic carrier (MG) with records of the magnetic fields of defects of an aluminum object, are presented. Contact access to the surface of a metal object, above which there is a layer of air and solid dielectric in an arbitrary proportion and with a total thickness of more than 5 mm, is completely excluded. There is also no access to the rear side of the object, since it is a massive dielectric. The object with MN was exposed to a complex magnetic field pulse with a duration from 1 μs to 200 μs. The studies were carried out in a field that passed through the metal. Raster images of hidden holes with a diameter of 3 mm and 6 mm in layers of aluminum with a thickness of 0.67 mm of samples made up of layers of aluminum of different thickness and separated by layers of dielectric (air) were obtained. The thickness of the metal layers of the samples was 1.96 mm and 2.96 mm. The measurements were carried out in hard-to-reach places of the samples. The algorithm of the developed method was drawn up. The method allows to significantly increase the sensitivity and accuracy of the control of the parameters of defects and to carry out their control of areas of objects where control by other methods is impossible.

Published: October 2021

BACKGROUND: Post-operative dysphagia is one of the most common complications of anterior cervical spine surgery (ACSS). OBJECTIVE: Examine post-operative structural and physiologic swallowing changes in patients with dysphagia following ACSS as compared with healthy age and gender matched controls. METHODS: Videofluoroscopic swallow studies of adults with dysphagia after ACSS were retrospectively reviewed. Seventy-five patients were divided into early (≤2 months) and late (> 2 months) post-surgical groups. Modified Barium Swallow Impairment Profile (MBSImP), Penetration-Aspiration Scale (PAS) scores, and pharyngeal wall thickness (PWT) metrics were compared. RESULTS: Significant differences were identified for all parameters between the control and early post-operative group. MBSImP Pharyngeal Total (PT) scores were greater in the early group (Interquartile Range (IQR) = 9–14, median = 12) versus controls (4–7, 5, P < 0.001) and late group (0.75–7.25, 2, P < 0.001). The early group had significantly higher maximum PAS scores (IQR = 3–8, median = 7) than both the control group (1–2, 1, P < 0.001) and late post-operative group (1–1.25, 1, P < 0.001). PWT was significantly greater in the early (IQR = 11.12–17.33 mm, median = 14.32 mm) and late groups (5.31–13.01, 9.15 mm) than controls (3.81–5.41, 4.68 mm, P < 0.001). CONCLUSION: Dysphagic complaints can persist more than two months following ACSS, but often do not correlate with validated physiologic swallowing dysfunction on VFSS. Future studies should focus on applications of newer technology to elucidate relevant deficits.
Application of CMSA to the Minimum Positive Influence Dominating Set Problem
Authors: Akbay Mehmet Anıl , Blum Christian
Published: October 2021

Construct, Merge, Solve & Adapt (CMSA) is a recently developed algorithm for solving combinatorial optimization problems. It combines heuristic elements, such as the probabilistic generation of solutions, with an exact solver that is iteratively applied to sub-instances of the tackled problem instance. In this paper, we present the application of CMSA to an NP-hard problem from the family of dominating set problems in undirected graphs. More specifically, the application in this paper concerns the minimum positive influence dominating set problem, which has applications in social networks. The obtained results show that CMSA outperforms the current state-of-the-art metaheuristics from the literature. Moreover, when instances of small and medium size are concerned CMSA finds many of the optimal solutions provided by CPLEX, while it clearly outperforms CPLEX in the context of the four largest, respectively more complicated, problem instances.

Authors: Aguiló Isabel , Massanet Sebastia , Riera Juan Vicente
Published: October 2021

The law of importation has attracted the interest of many researchers devoted to fuzzy implication functions in the last decades. This property has several important applications, especially in approximate reasoning and image processing. Several generalizations of this property have been proposed. Specifically, one generalization related to the law of migrativity was recently introduced by Baczyński et al. in which two fuzzy implication functions are involved. In this paper, some advances on the solution of this functional equation for the particular case where the involved fuzzy conjunction is a t-norm are presented. Indeed, a complete characterization of all those pairs of fuzzy implication functions with a strict natural fuzzy negation satisfying the generalized law of importation is achieved.

Published: October 2021

The automated analysis of different trends in online debating forums is an interesting tool for sampling the agreement between citizens in different topics. In these online debating forums, users post different comments and answers to previous comments of other users. In previous work, we have defined computational models to measure different values in these online debating forums. A main ingredient in these models has been the identification of the set of winning posts trough an argumentation problem that characterizes this winning set trough a particular argumentation acceptance semantics. In the argumentation problem we first associate the online debate to analyze as a debate tree. Then, comments are divided in two groups, the ones that agree with the root comment of the debate, and the ones that disagree with it, and we extract a bipartite graph where the unique edges are the disagree edges between comments of the two different groups. Once we compute the set of winning posts, we compute the different measures we are interested to get from the debate, as functions defined over the bipartite graph and the set of winning posts. In this work, we propose to explore the use of graph neural networks to solve the problem of computing these measures, using as input the debate tree, instead of our previous argumentation reasoning system that works with the bipartite graph. We focus on the particular online debate forum Reddit, and on the computation of a measure of the polarization in the debate. Our results over a set of Reddit debates, show that graph neural networks can be used with them to compute the polarization measure with an acceptable error, even if the number of layers of the network is bounded by a constant.

Towards Expert-Inspired Automatic Criterion to Cut a Dendrogram for Real-Industrial Applications
Authors: Suman Shikha , Karna Ashutosh , Gibert Karina
Published: October 2021

Hierarchical clustering is one of the most preferred choices to understand the underlying structure of a dataset and defining typologies, with multiple applications in real life. Among the existing clustering algorithms, the hierarchical family is one of the most popular, as it permits to understand the inner structure of the dataset and find the number of clusters as an output, unlike popular methods, like k-means. One can adjust the granularity of final clustering to the goals of the analysis themselves. The number of clusters in a hierarchical method relies on the analysis of the resulting dendrogram itself. Experts have criteria to visually inspect the dendrogram and determine the number of clusters. Finding automatic criteria to imitate experts in this task is still an open problem. But, dependence on the expert to cut the tree represents a limitation in real applications like the fields industry 4.0 and additive manufacturing. This paper analyses several cluster validity indexes in the context of determining the suitable number of clusters in hierarchical clustering. A new Cluster Validity Index (CVI) is proposed such that it properly catches the implicit criteria used by experts when analyzing dendrograms. The proposal has been applied on a range of datasets and validated against experts ground-truth overcoming the results obtained by the State of the Art and also significantly reduces the computational cost.

Authors: Yauri José , Hernández-Sabaté Aura , Folch Paul , Gil Débora
Published: October 2021

The study of mental workload becomes essential for human work efficiency, health conditions and to avoid accidents, since workload compromises both performance and awareness. Although workload has been widely studied using several physiological measures, minimising the sensor network as much as possible remains both a challenge and a requirement. Electroencephalogram (EEG) signals have shown a high correlation to specific cognitive and mental states like workload. However, there is not enough evidence in the literature to validate how well models generalize in case of new subjects performing tasks of a workload similar to the ones included during model’s training. In this paper we propose a binary neural network to classify EEG features across different mental workloads. Two workloads, low and medium, are induced using two variants of the N-Back Test. The proposed model was validated in a dataset collected from 16 subjects and shown a high level of generalization capability: model reported an average recall of 81.81% in a leave-one-out subject evaluation.

Published: October 2021

Deep learning (DL) networks have proven to be crucial in commercial solutions with computer vision challenges due to their abilities to extract high-level abstractions of the image data and their capabilities of being easily adapted to many applications. As a result, DL methodologies had become a de facto standard for computer vision problems yielding many new kinds of research, approaches and applications. Recently, the commercial sector is also driving to use of embedded systems to be able to execute DL models, which has caused an important change on the DL panorama and the embedded systems themselves. Consequently, in this paper, we attempt to study the state of the art of embedded systems, such as GPUs, FPGAs and Mobile SoCs, that are able to use DL techniques, to modernize the stakeholders with the new systems available in the market. Besides, we aim at helping them to determine which of these systems can be beneficial and suitable for their applications in terms of upgradeability, price, deployment and performance.

Authors: Khalid Saif , Abdulwahab Saddam , Rashwan Hatem A. , Cristiano Julián , Abdel-Nasser Mohamed , Puig Domenec
Published: October 2021

Quality of retinal image is vital for screening of ailments pertaining to eye such as glaucoma, diabetic retinopathy (DR) and age related macular degeneration. Therefore, assessing quality of retinal image prior to any kind of diagnosis has assumed significance in Computer Aided Desgin (CAD) applications. The rationale behind this is that reliability of retinal image is to be guaranteed to have dependable diagnosis. In this paper, we propose a novel retinal fundus image quality assessment (RIQA) method based on autoencoder network to assess retinal images if the image is acceptable for screening or not. The autoencoder network architecture is well suited to precisely to properly represent the key features of the image quality, especially when the network can correctly reconstruct the input image. The proposed model consists of encoder and decoder successive networks. The encoder will be used for representing the features of the input image. In turn , the decoder will be used for reconstruct the input image. The features get from encoder network will then be fed to a classifier in order to classify the quality of retinal image to two classes: gradable or ungradable. The experimental results revealed more useful assessment and the proposed deep model provides a superior performance for RIQA. Thus, our model can serve real-world Clinical Decision Support Systems in the healthcare domain.

This blending produces a distinct compositional style associated with Grainger, featuring simple forms and textures, melodies inspired by traditional folk songs, extended tertian harmony, and an emphasis on voice leading. Grainger’s works often cross genres and explore various instrumentations and stylistic choices. This paper attempts to further define and explain Grainger’s style by analyzing two of his original works that were arranged for the military band setting, namely Children’s March: Over the Hills and Far Away and Colonial Song. Examining these two works through the lens of harmony, melody, form, texture, and rhythm reveals key aspects of Grainger’s early compositional style. Several stylistic choices were found to recur, including Grainger’s use of counterpoint, voice leading, descending chromaticism, specific patterns of articulations, and tension created by increased note density.

As political polarization increases and mental health worsens, it is becoming crucial to investigate the potential link between these. This project investigated the link between political party and mental health in the United States. Data was analyzed from previous U.S. elections, Mental Health America, and the Substance Abuse and Mental Health Services Administration to investigate the relationships in four studies. The first analyzed current associations between state mental health rankings and voting margins in the 2020 presidential election. The second analyzed this same connection but over previous years. The third compared the percentage of liberal control in the government with the percentage of American adults receiving mental health care services to uncover if the party in power had an effect on overall mental health. The fourth analyzed voting margins and state mental health rankings at the end of the term to determine if mental health was associated with being governed by the party for which the state voted. Studies 1, 2, and 4 were found to have significant relationships at a 99% confidence level. This indicates that voting liberal is associated with better mental health rankings at the state level, both currently and throughout previous elections. It also signifies that being governed by the party for which the state voted is associated with better mental health at the state level. In future studies, it may be beneficial to conduct individual assessments to determine if this relationship exists only at the state level.

The Coronavirus Disease 2019, named COVID-19 is a global problem. According to the declaration of the World Health Organization (WHO), it is a novel and extreme outbreak, spreading worldwide. Firstly, numerous patients reported exposure in Wuhan City, China at a large animals and seafood market. Accordingly, the first idea is suggesting the animal-to-human transmission of this infection pathogen. Next, since then, numerous patients have decelerated no exposure to animal shops, indicating that human-to-human transmission is occurring. The new coronavirus (2019-nCoV) is a positive RNA virus with a 29.8 kb genome and S, E, M, N, and Orf1 gene fragments. The most popular method for 2019-nCoV detection is genome-based approaches, like Polymerase Chain Reaction (PCR)-based tests that require expensive experimental equipment, a controlled working environment, and high-trained technicians; they are often lacking in massive viral outbreaks. Therefore, another rapid and simple genome-based assay was evaluated for this pathogen. In this review study, the RT-LAMP technique, as the main isothermal amplification assays with less time consumption and without the need for expensive equipment, compared to conventional PCR-based methods to 2019-nCoV identification, was discussed. Accordingly, the advantage or disadvantage of these techniques was compared. The obtained data indicated that this molecular and isothermal method could be used as a successful one-step process for portable screening and the rapid identification of 2019-nCoV.

The situation in the construction complex of the state and crisis phenomena in it are shown. It is proposed to return to the basic components of system management of the industry, lost due to spontaneous pseudo-market processes. Problems that need to be overcome are systematized, they are the following: attracting investments, increasing effective demand in the domestic market, strengthening the competitiveness of production, the predominance of innovative technologies, increasing the quality of products and facilities, bringing the legal framework to European standards, training of employees and managers. The state of the housing market, the importance of its openness, transparency, systematization and regulation are described. The special importance of the regulatory function of the state in the current situation is pointed out. The importance and role of comprehensive activities for housing construction economic growth is emphasized. The need to create conditions for increasing the volume of products sold under international agreements through investment and interstate projects is noted. The relationship between the results of the construction industry and the effective use of human capital is given, for which each company needs measures to improve work with staff, improve their skills, financial incentives and social security. The expediency of introducing the mechanism of energy service in construction, which is part of the management system with subsystems of planning, organization, regulation, motivation and control, is proved. The role of methods for evaluating the effectiveness of innovative activities of enterprises to ensure quality and effective management of production processes is analyzed. The information on development schemes of the organization at registration of the allowing documentation, financing, designing, market research, selection of participants, accounting, construction, property management is provided. The function of settlements' territories as separate objects at construction of inhabited premises is defined. Award on the need for construction and reconstruction of "sleeping" areas in cities, which requires significant investment, development of building structures, as well as established close relationships with industrial, commercial, cultural, entertainment and other facilities.

Objective: To study and understand the population's perception in a region of the Estado de Mexico about the role of certified organic food in health and the environment, as well as the economic impact generated by its consumption.

Desing/methodology/approach: A survey was conducted among a population sample of 10 municipalities in the Estado de Mexico, which consisted of seven questions related to certified organic food.

Results: The population has an idea about what certified organic food is, although they confuse it with other types of food. 

Study limitations/ implications: Results were obtained from an e-mail survey because this study was conducted during the current 2020-2021 pandemic.

Findings/conclusion: The information obtained suggests that the population has a great perception about the intake of certified organic food, but there is confusion about other types of food. However, the population is willing to consume them because of their potential health and environment benefits.
