ENVIRONMENTAL EDUCATION

We can observe that, at present, the social body suffers from the dilemma of the excess of the inadequate corollary creation of solid waste. This excessive amount of waste has been worrisome because, if not properly collected and disposed of, it causes serious consequences to health and the environment. Thus, the reluctance of the non-management of solid waste is numerous and includes environmental, economic, social, and health aspects. In this scenario, it is clear that waste cannot be completely eliminated; however, it is possible to decrease it by reducing the amount of waste and recycling as much as possible. It is true that the contemporary world is characterized by an almost constant state of crisis, however, to recycle or reuse has the sense to restrain what is used, to limit waste and residues, to protect the environment, to conserve and defend the ecosystem. For this, there is a need to moderate this expressed consumption, not only to use what is necessary, but also to reuse what is possible. The optics of the "3R's" concept aims to contain the ecosystemic shock with applicability to the development of new products. In this sense, it is essential to emphasize education, as an agent of change, for the development of people into informed and active citizens. In view of the above, the objective of this work was to observe, the perception of children in the first year of elementary school about the environment to, subsequently, make them aware in a critical and reflective way of how we relate to each other and how we can improve our environment through the reduction and reuse of waste. The concept of the three Rs in this case study was used, therefore, to clarify and promote reflection regarding excessive shopping, the reuse of what would go to waste such as cans, cardboard, bottles among others, and finally, to offer the possibility of converting items no longer used into other creations. This study contributed to the awareness and preservation of the environment and its didactic-pedagogical sequence promoted progression in the visuomotor, motor, motor, playful, affective, and critical-reflexive aspects, for the promotion of the acquisition and strengthening of competencies and skills.
Predictors of knowledge sharing behaviour on Sustainable Development Goals among library personnel in Nigeria

The study was carried out to investigate the predictors of library personnel’s knowledge sharing behaviours and its implication for achieving sustainable development goals, using the theory of planned behaviour. Survey research design was adopted for the study whereby a structured questionnaire was used to elicit data from 100 registered library personnel in Anambra State, Nigeria. Total enumeration was adopted as the sampling technique to obtain the population sample. The study revealed that attitude, perceived behavioural control and subjective norm had a significant influence on knowledge sharing intention at P < 0.05. Also, knowledge sharing intention had a positive and significant influence on SDGs actualization. The study concluded that for library personnel to contribute greatly to the realization of Sustainable Development Goals, they must ensure effective knowledge sharing behaviour on Sustainable Development Goals-related information. Therefore, management of libraries should set up structures that foster knowledge sharing. Also, library personnel should develop themselves with the required skills and knowledge on Sustainable Development Goals, which will stimulate a high rate of knowledge sharing.
ON PRECISION ACOUSTIC WAVE CALCULATION IN A FREQUENCY DOMAIN

The accuracy of the calculation of acoustic problems formulated in the frequency domain is presented in this work. The issues of the acoustic point sources modelling were discussed and the influence of frequency as well as the impact of the geometry of the analysed area on the accuracy of calculations were indicated. Speaking about the influence of geometry, we mean not only discretization but also the configuration of the considered area, such as for example point sources localization close to the outer edge.
Preschoolers’ ways of experiencing numbers

In this paper we direct attention to 5–6-year-olds’ learning of arithmetic skills through a thorough analysis of changes in the children’s ways of encountering and experiencing numbers. The foundation for our approach is phenomenographic, in that our object of analysis is differences in children’s ways of completing an arithmetic task, which are considered to be expressions of their ways of experiencing numbers and what is possible to do with numbers. A qualitative analysis of 103 children’s ways of encountering the task gives an outcome space of varying ways of experiencing numbers. This is further analyzed through the lens of variation theory of learning, explaining why differences occur and how observed changes over a prolonged period of time can shed light on how children learn the meaning of numbers, allowing them to solve arithmetic problems. The results show how observed changes are liberating new and powerful problem-solving strategies. Emanating from empirical research, the results of our study contribute to the theoretical understanding of young children’s learning of arithmetic skills, taking the starting point in the child’s lived experiences rather than cognitive processes. This approach to interpreting learning, we suggest, has pedagogical implications concerning what is fundamental to teach children for their further development in mathematics.
Depressed basal hypothalamic neuronal activity in type-1 diabetic mice is correlated with proinflammatory secretion of HMBG 1 Short title : Inflammation and neuronal activity in Akita type-1 diabetic mice

We recently found indicators of hypothalamic inflammation and neurodegeneration linked to the loss of neuroprotective factors including insulin-like growth factor (IGF-1) and IGF binding protein-2 (IGFBP-3) in mice made diabetic using streptozotocin (STZ). In the current work, a genetic model of type-1 diabetes (Ins2 mouse) was used to evaluate changes in neuronal activity and concomitant changes in the proinflammatory mediator high-mobility group box-1 (HMBG1). We found basal hypothalamic neuronal activity as indicated by manganeseenhanced magnetic resonance imaging (MEMRI) was significantly decreased in 8 month old, but not 2 month old Ins2 diabetic mice compared to controls. In tissue from the same animals we evaluated the expression of HMBG1 using immunohistochemistry and confocal microscopy. We found decreased HMBG1 nuclear localization in the paraventricular nucleus of the hypothalamus (PVN) in 8 month old, but not 2 month old diabetic animals indicating nuclear release of the protein consistent with an inflammatory state. Adjacent thalamic regions showed little change in HMBG1 nuclear localization and neuronal activity as a result of diabetes. This work extends our previous findings demonstrating changes consistent with hypothalamic neuroinflammation in STZ treated animals, and shows active inflammatory processes are correlated with changes in basal hypothalamic neuronal activity in Ins2 mice.
Evaluating the Effectiveness of Digital Content Marketing Under Mixed Reality Training Platform on the Online Purchase Intention

The purpose of this research is to investigate the effectiveness of Digital Content Marketing (DCM) on a Mixed Reality (MR) training platform environment with the consideration of online purchase intention (OPI) through social media. E-commerce today encounters several common issues that cause customers to have reservations to purchase online. With the absence of physical contact points, customers often perceive more risks when making purchase decisions. Furthermore, online retailers often find it hard to engage customers and develop long-term relationships. In this research, a Structural Equation Model (SEM) is proposed to examine the efficacy of DCM from both immediate and long-term OPI. The results examine whether adopting DCM on an MR training platform environment through social media brings positive results in OPI. Empirical research was carried out through online questionnaires collected in 2021 and 2022. A total of 374 questionnaires were qualified for data analysis in this study, conducted with IBM SPSS and AMOS. The results imply that DCM is critical to stimulating both immediate and long-term OPI. The immediate OPI is positively affected by increasing perceived value through MR in DCM. Regarding the long-term OPI, increased customer engagement with DCM under MR environment can cultivate brand trust and significantly affect the long-term OPI.
TRIBOLOGICAL EVALUATION OF INTAKE VALVE AND VALVE SEAT OF A DIESEL CYCLE ENGINE IN REAL OPERATING CONDITIONS

Automotive industry demands products that work under extreme conditions. The development of components for internal combustion engines is an action to improve this product, so that it reaches the required life with acceptable levels of wear and respecting the legal operating limits, such as values of emission pollutants. In view of these requirements, it is necessary to study components considered critical, which are known to influence the performance of the engine. So, within this universe the tribology of the intake valve and valve seat insert is an important set, that must receive attention to its wear and consequently its influence on the engine degradation, in the emission of pollutants and performance related to the operational maintenance requirements and life of the product. The aim of this work is to evaluate the behavior of the tribological intake pair, valve and valve seat insert, submitted to dynamometer and vehicular tests (real operating conditions), regarding the level and type of wear occurred in the pair. Correlating the results obtained with legal and operational performance requirements of a Diesel cycle engine, as well as the characterization of the wear type occurred in the tribological pair, with the related literature.
Potential benefits of agile project management in improving construction project performances: A case study of Iraq

Due to poor performances in construction projects, there is a necessity to apply novel project management approaches instead of traditional ones. Recently, although new project management methods have emerged and applied in different industries, the construction industry has stayed behind in implementing these techniques. The agile Project Management (APM) approach is one of these methods, and it has been highly discussed recently. As developing countries considerably suffer from poor performance in construction projects, applying new project management methods has gained more importance in these territories. Even though different studies attempted to understand the applicability of the APM, it is also necessary to explore the potential benefits of the agile methods for the construction industry. For this purpose, we surveyed 140 construction experts for the prioritization of factors and received responses on the potential advantages of the APM regarding team and project performance in construction. The results achieved from the Iraq field study demonstrate that the APM could be feasible for the construction industry and could effectively bring solutions to the project performance issues. We also concluded that the adverse effects of poor project performance, such as quality defects, schedule variances, cost overruns, and low productivity, could be eliminated especially in the construction industry of developing countries, through APM approaches.
Exploring Value Generation in Target Value Design Applying a Value Analysis Model

Target value design (TVD) is a management approach that applies target costing in the design and construction industry. TVD enables a project environment with favorable characteristics to generate value. However, because the TVD’s primary assessment is cost, target cost can be met without necessarily achieving the project’s full value. This research applies the action research approach to implement TVD in a housing project and explores the value generation of the project using a value analysis model (VAM) to study the balance between cost and value fulfillment in the product and design process. According to the results, even though the target cost was achieved, the desired value of the project was not achieved during the project design. However, there is a tendency to increase value over time to a greater extent in the product and not so much in the process. The main contributions of this study are the possibility of comparing cost and value, identifying the emphasis of product over process and cost over value throughout the TVD project. This study enhances the literature on project value generation and maximization, offering new knowledge for a better understanding of how to conduct a value analysis in combination with costing in TVD projects.
Screen Control System Based on Fingertip Tracking : AirFlick

This paper suggests a method of extracting fingertips from 3D information obtained from single-depth cameras in a smart-device environment, and for controlling the screens without directly touching them. This method extracts fingertips from hand images, and controls the screen by reading the fingertips’tracking information. First, we extract hand areas in real time by utilizing depth information, and remove the noise by preprocessing the extracted hand areas to obtain the hand area through labeling. Next, we extract prospective fingertips from the areas and obtain final fingertips after a verification process. Fingertip movement information is indicated as a graph, and movement at a pace exceeding a certain critical level generates flick events. Finally, the key codes obtained from such events are relayed to application contents to control the screen.
Modelling damping sources in monopile-supported offshore wind turbines

Vibration damping in offshore wind turbines is a key parameter to predict reliably the dynamic response and fatigue life of these systems. Damping in an offshore wind turbine originates from different sources, mainly, aerodynamic, structural, hydrodynamic, and soil dampings. The difficulties in identifying the individual contribution from each damping source have led to considerable uncertainty and variation in the values recommended. This paper proposes simplified but direct modelling approaches to quantify the damping contributions from the aerodynamic, hydrodynamic, and soil interactions. Results from these models were systemically compared to published values and when appropriate with simulation results from the software package FAST. The range of values obtained for aerodynamic damping confirmed those available in the literature, and blade element modelling theory was shown to provide good results relatively efficiently. The influence of couplings between fore‐aft and side‐side directions on the aerodynamic damping contribution was highlighted. The modelling of hydrodynamic damping showed that this damping is much smaller than usually recommended and could be safely ignored for offshore wind turbines. Soil damping strongly depends on the soil specific nonlinear behaviour.
THE BROADENING OF CREATIVE WRITING STUDENTS’ CONCEPTS ABOUT FANFICTIONS

The multimodal gerne fanfictions have been one of the commonest cyberliterary texts produced on the internet. However, the various definitions of fanfictions seem not to be related to the cyberspace (JENKINS, 1992; TUSHNET, 1997; PUGH, 2005; THOMAS, 2006; HELLEKSON, 2014; COPPA, 2017). Therefore, the first objective of this article was to identify the students’ actual concepts about fanfictions (VYGOTSKY, 2004, 2007). The qualitative data was collected in a fanfictional creative writing (FCW) course. This course was organized and taught based on the Vygotskian sociocultural theory. The second objective was then to analyze if the FCW course did help its students broaden their concepts about fanwriting. As a result, the FCW students displayed signs of syncretizing, complexifying and conceptualizing about the fanwriting process.
Future Primary School Teachers’ Achievement Motivation in Remote Learning Process

Thesis. The aim of the study was to determine the level of achievement motivation of future primary school teachers during remote learning, as well as to describe each of the study dimensions characterising the achievement motivation. Methods. The study involved 162 (N=162) first-course students from Latvia, two of them were male. The study raised three research questions. RQ1: At what level do students assess each of the study dimensions that characterise the achievement motivation? RQ2: What factors hinder students from taking the initiative in the study process? RQ3: How do students monitor the quality of task performance? This paper defined five study dimensions to be assessed by students: initiative, persistence, quality of task performance, self-efficacy, seizing and exploiting opportunities. Results. The study found that four of the previously mentioned dimensions were highly assessed by the students. The dimension that characterises the persistence was assessed at a medium level. The students believe that lack of time, family conditions, and full-time work accompanying their study are the most common factors that hinder learning initiatives. To monitor the quality of task performance, most students bear in mind the assessment criteria provided by the lecturer, which are used as indicators to achieve an excellent result. Conclusion. The study concluded that the students also have a high motivation for achievement when studying remotely. In further studies, it is necessary to determine if any significant changes happen in the long run related to students’ achievement motivation when remote learning continues.

Possible, alternative explanations of the T2K observation of the $\nu_e$ appearance from an initial $\nu_\mu$

An alternative explanation to the emergence of sin^2(2 theta_13) > 0 is discussed. It is pointed out that the recorded T2K events might have been due to some other new physics in the neutrino sector, related to the LSND/MiniBooNE sterile neutrino anomalies, for which there is nowadays a growing evidence. The presently running ICARUS detector with the CNGS beam will be able to distinguish between these two possible sources of the effect

The approach is compose of ROI blocks extraction and crowd block recognition. ROI blocks can be extracted with circle gradient operator and weighted geometric filtering. Crowd blocks are recognized by support vector machine, which combines histogram of oriented gradient and circle gradient. The experimental results show thatthe approach works effectively in different scenes.
The Brazilian Pirarucu supply chain: situation, perspectives, and challenges

This study suggests that pirarucu is a fish capable to have competitive products in the national premium fish market and analyze the opportunities and constraints of this supply chain in Brazil. To achieve that, a semi-structured interview was conducted with 22 players of the cultivated pirarucu supply chain in Brazil, resulting in more than 13 hours of dialogue to understand who the players are, and the main challenges and opportunities for this market. The pirarucu products (such as frozen fillet and loin) are premium products and can become competitive in the niche market of value-added fish, if their constraints are overcome, since they have intrinsic potentialities and extrinsic values to the consumer. The non-conformity of the information added to the lack of knowledge about the species were identified as the main limitations of the organization of the supply chain. Fish farmers show interest in strengthening the cultivated pirarucu supply chain. The processing industry and the consumers demand a regular supply, and input suppliers realize that this is an important national market. In any case, there is a market for premium pirarucu, and it is noticeable that there is a demand for superior quality fish, and pirarucu presents several characteristics valued by the consumer.
Step Climbing Control of Snake Robot with Prismatic Joints

The ultimate goal of this research study is to perform continuous rather than sequential movements of prismatic joints for effective motion of a snake robot with prismatic joints in a complex terrain. We present herein a control method for robotic step climbing. This method is composed of two parts: the first involves the shift reference generator that generates the joint motion for climbing a step, and the other is use of the trajectory tracking controller, which generates the joint motion for the head to track the target trajectory. In this method, prismatic joints are divided into those that are directly controlled for climbing a step and those that are represented as redundancies. By directly controlling the link length, it is possible to prevent the trailing part from back motion when climbing a step, and to avoid a singular configuration in the parts represented as redundancies. A snake robot that has rotational and prismatic joints and can move in three-dimensions was developed, and the effectiveness of the proposed method was demonstrated by experiments using this robot. In the experiment, it was confirmed that the proposed method realizes the step climbing, and the link length limitation using the sigmoid function works effectively.
A Computer Code (USPOTF2) for Unsteady Incompressible Flow Past Two Airfoils

Abstract : A numerical code, USPOTF2, has been formulated to solve the potential flow for two airfoils executing unsteady motions is an inviscid incompressible flow medium. This code is an extension of an existing code U2DIIF, which does the same calculations for the single airfoil case. The technique uses the well known Panel Methods for steady flow and extends it to unsteady flow by introducing a wake model which creates a non-linear problem due to the continuous shedding of vortices into the trailing wake. The presence of the second airfoil introduces a set of non-linear coupled equations for the Kutta condition. Numerous case-runs are presented to illustrate the capability of the code. The case of the step change in angle of attack is compared with Giesing's work. All other case-runs are illustrated together with the results for the single airfoil case.
