Knowledge and Perception on Animal Welfare in Chilean Undergraduate Students with Emphasis on Dairy Cattle

The objectives of this study were to determine differences in knowledge and perception of animal welfare (with emphasis on dairy cattle) among undergraduate students from two universities with different missions and visions and between students from different faculties. One thousand surveys were obtained from Universidad de Chile (UChile; n = 500) and Pontificia Universidad Católica de Chile (PUC; n = 500) students. The students from both universities were from the following faculties: Agronomy, Architecture, Biology, Economic Sciences, Psychology, Law, Philosophy, Basic Education, Civil Engineering and Medicine. The majority (77%) of students from both universities were aware of animal welfare. Most (56%) students understand animal welfare as the ’mental and physical state of animals’. Regardless of their faculty, around 97% of the total respondents perceived animal welfare as important for production systems. Regarding specific knowledge about cows’ welfare related to milk management and behavior, students from Economic Sciences, Psychology, Law, Philosophy, Basic Education, and Civil Engineering had less (p < 0.001) self-reported knowledge about cows´ basic behavior and specific management practices such as milking and were more negative in their perceptions of dairy production. Overall, results showed that the students’ faculty explained most of the differences among undergraduate students in relation to their perceptions and knowledge about animal welfare. Our data is important, as undergraduate students will make purchasing and power decisions as well as having potential influence on future policies that could modify the animal production industry.

Identification and Mapping of Manufacturability Constraints for Extrusion-Based Additive Manufacturing

This article develops and demonstrates a set of design-focused manufacturability constraints for the fused deposition modeling/fused filament fabrication (FDM/FFF) process. These can be mapped from the basic behavior and process characteristics and formulated in terms of implicit or explicit design constraints. When the FDM/FFF process is explored and examined for its natural limitations and behavior, it can provide a set of manufacturing considerations (advantages, limitations, and best practices). These can be converted into manufacturing constraints, which are practical limits on the ability of the process. Finally, these can be formulated in terms of design–useful manufacturability constraints. Many of the constants and parameters must be determined experimentally for specific materials. The final list of 54 major manufacturability constraints presented in this work will better inform designers considering using FDM/FFF as a manufacturing process, and help guide design decisions. After derivation and presentation of the constraint set, extensive discussion about practical implementation is provided at the end of the paper, including advice about experimentally determining constants and appropriate printing parameters. Finally, three case studies are presented which implement the constraints for simple design problems.

Effects of Using Music Methods, 3D Glasses and Behavioral Control on Children’s Anxiety during Dental Treatment

Introduction: Dental anxiety in children is a challenge in managing patients. The effect of this anxiety may continue until adolescence and be a reason for avoiding dental treatments. The aim of this study was compare the effectiveness of using music, 3D glasses and behavioral control methods on children’s anxiety during dental treatments. Materials and Method: This Experimental cross sectional study carried out on 96 children aged between 5-8 years without any systemic. The children were divided into three groups; control (basic behavior guidance techniques without distraction), audio (basic techniques plus music) and AV (basic techniques plus 3D AV) distraction groups. The anxiety score was assessed by using MCDASf method, before local anesthesia, after LA and after restoration. Pain rate measured with VAS and the behavior of children during dental treatment measured with Houpt index. Data were analyzed by one-way ANOVA with the 0.05 level of significance. Results: The mean of anxiety in different stages before starting work, after anesthesia and after repair, was significantly different in the 3D glasses group (p value = 0.004), using music (p value = 0.018) and behavioral control (p value = 0.002). The lowest anxiety level in the 3D glasses group and the highest anxiety in the control group was. The best group in reducing the amount of pain after anesthesia and cooperation was the 3D glasses group. Conclusion: Use of 3D glasses in dental treatment can decrease dental anxiety in children. And children cooperation with 3D glasses was better than other methods.

A Deep Learning Approach for DDoS Attack Detection Using Supervised Learning

This research presents a novel combined learning method for developing a novel DDoS model that is expandable and flexible property of deep learning. This method can advance the current practice and problems in DDoS detection. A combined method of deep learning with knowledge-graph classification is proposed for DDoS detection. Whereas deep learning algorithm is used to develop a classifier model, knowledge-graph system makes the model expandable and flexible. It is analytically verified with CICIDS2017 dataset of 53.127 entire occurrences, by using ten-fold cross validation. Experimental outcome indicates that 99.97% performance is registered after connection. Fascinatingly, significant knowledge ironic learning for DDoS detection varies as a basic behavior of DDoS detection and prevention methods. So, security professionals are suggested to mix DDoS detection in their internet and network.

THE MAIN BEHAVIORAL MODELS OF PERSONS OF DIFFERENT TYPES OF CHARACTER ACCENTUATION WHEN THEY PROVIDE INACCURATE INFORMATION ABOUT THE CIRCUMSTANCES OF A CRIMINAL OFFENSE AND TACTICS FOR VERIFYING THISINFORMATION

The bodies of preliminary investigation make high demands on the competence of the investigator, one of the important varieties of which is tactical and psychological. The tactical and psychological competence of an investigator is his/her ability to tactically and psychologically competently carry out investigative (search) actions to ensure the effectiveness and efficiency of the pre-trial investigation of a criminal offense. One of the significant and leading skills of the investigator, which condition and determine tactical and psychological competence, is the ability to: 1) collect, verify and evaluate evidence “... to establish circumstances that are important for criminal proceedings …” (clause 2 Article 91 of the Criminal Procedure Code of Ukraine); 2) verify information and data on the circumstances of the criminal offense; 3) establish the objective truth in the circumstances of the criminal offense; 4) determine the typology of the personality (witness, victim, suspect, accused) for the selection of the most effective methods of influence, determination of tactics of actions and tactics, etc. One of the most widespread and empirically investigated personality typologies is the theory of character accentuation by K. Leonhard and A. Lichko. The authors described in sufficient detail the types they identified and demonstrated on specific examples the typical behavioral models for these types. Based on these scientific theories and many years of psychological practice, the author, in the article, discloses the basic behavior models of a person of a certain type of character accentuation, which provides inaccurate information about the circumstances of a criminal offense. As well as his typical emotional and behavioral reactions to a direct indication by the investigator about its unreliability indications. Tactical techniques are proposed for verifying the information provided by persons of various types of character accentuation. It is noted that in the course of investigative (search) actions, to identify and establish the veil of a person's message of false information about the circumstances of a criminal offense, the investigator must pay attention to all signs that may indicate a lie, that is, signs, signals, indicators, behavior patterns, etc. It is emphasized that to verify information regarding the circumstances of a criminal offense, employees of pre-trial investigation bodies and operational units must undergo advanced training in such thematic courses as “Cognition of personality psychology” and “Information verification technology”. This will enhance the efficiency and effectiveness of investigative, operational, and investigational activities and will ensure the quality of preliminary investigation of criminal offenses.

Spiritual and mental foundations of personality self-determination against the background of the importance of environmental problems

Rigorous transformations taken place in Russian society owing to information influence had drastically altered moral behavior patterns of an individual by designing different patterns of social reality. Transformation of reflexive structures of mental programs came into contradiction with normative (traditional, basic) behavior patterns of Russians that can be characterized as non-reflexive, conveying successive values and meanings, as well as mechanisms of development and self-determination of an individual. Hence, the article addresses features of self-determination of an individual in modern society determined by spiritual and mental sources of development. Trans-disciplinary approach is the theoretical and methodological basis of the scientific research. Analysis of mental programs and mental traditional matrixes of Russians, as well as spiritual meanings and values that define the process of self-determination corroborate the effectiveness of the research. Analysis of research papers suggests that self-determination relates to: self-actualization of potential, self-realization, spiritual self-comprehension, destination and integrity achievement, as well as to supreme values and meanings of culture of each civilization.

The collapse of the spindle following ablation in S. pombe is mediated by microtubules and the motor protein dynein

A microtubule-based machine called the mitotic spindle segregates chromosomes when eukaryotic cells divide. In the fission yeast S. pombe, which undergoes closed mitosis, the spindle forms a single bundle of microtubules inside the nucleus. During elongation, the spindle extends via antiparallel microtubule sliding by molecular motors. These extensile forces from the spindle are thought to resist compressive forces from the nucleus. We probe the mechanism and maintenance of this force balance via laser ablation of spindles at various stages of mitosis. We find that spindle pole bodies collapse toward each other following ablation, but spindle geometry is often rescued, allowing spindles to resume elongation and segregate chromosomes. While this basic behavior has been previously observed, many questions remain about this phenomenon’s dynamics, mechanics, and molecular requirements. In this work, we find that previously hypothesized viscoelastic relaxation of the nucleus cannot fully explain spindle shortening in response to laser ablation. Instead, spindle collapse requires microtubule dynamics and is powered at least partly by the minus-end directed motor protein dynein. These results suggest a role for dynein in redundantly supporting force balance and bipolarity in the S. pombe spindle.

On a Very Basic Behavior in Science: Importance and Issues with Quotations

This journal, founded in 1968, not only has a publication history of more than 5 decades but also stands for a distinct scientific focus in psychiatric pharmacology or psychopharmacology: the research on medication treatments for mental disorders. At some point, it is worth taking a broader look at what we are doing in psychiatry or in medicine in general. That is why, in this issue, we are publishing a study by Christopher Baethge 1 that typically may not fit into the scope of Pharmacopsychiatry. As a psychiatrist and an editor, Baethge carried out an investigation in an underresearched area: the accuracy and significance of citations in psychiatric journals.

Revisiting Parameters of Bioinspired Behavior Models in Group Foraging Modeling

Using bioinspired models and methods is one of approaches for solving tasks of swarm robotics. In this paper one of such tasks, modeling of foraging, and it’s solving by creating analogues of social structures of ants and models of feeding behavior are considered. The most important characteristics of ants’ colonies for modeling were defined – individuals number in society and it’s structure, workers’ speed, a communication distance and working area size. Besides, existing experimental basis (a group of robots and a polygon) was estimated for a usage as a hardware platform for experiments. Several models of feeding behavior were considered: a model without foragers’ functions differentiation and a model with differentiation on active and passive ones. Active foragers look for resources by themselves, then they involve passive foragers; passive foragers are settled on a base, while are not involved in harvesting. A set of finite state machines describe the behavior of agents: basic automatons (provide basic behavior functions) and a meta- automaton, that switches with some conditions an execution of basic automatons. Basic movements were tested on experimental basis. A complex test of models were conducted in a simulation program Kvorum. An analogue of real polygon was made in the program. Modeling consists of series of experiments for every model in which agents must harvest resources. Series differ from each other by number of agents. For models’ quality estimation a ratio of received energy to average obtaining time. Experiments settle that model with functions differentiation works more effective.
