Abscesso renal em pediatria - desafios para o diagnóstico e manejo: relato de caso
Authors: Santos Alexandre , Andrade Maria , Hatanaka Eduardo
Published: May 2023

Objective: To discuss the diagnostic difficulties of renal abscess in the pediatric age and warn pediatrics about the possible complications of urinary tract infections. Case description: A 16-year-old boy with autism spectre disorder and Duchenne muscular dystrophy presented at the emergency care unit with persistent fever despite the use of antibiotics to treat an urinary tract infection. Although there was leukocyturia, the urine culture was negative. Ultrassound of the urinary tract showed no significant findings. Computed tomography showed multiple renal abscesses in the right kidney. A puncture guided by ultrasound was performed. The culture of the liquid resulted in growth of ESBL Klebsiella pneumoniae. A 21 day course of intravenous antibiotic after the procedure resulted in complete resolution of signs and symptoms. Comments: Renal abscess is a rare condition in the pediatric population. However, it must be considered in the differential diagnosis of prolonged fever and when there is a nonfavorable evolution of urinary tract infection, mainly in recurrent episodes. The early diagnosis of this condition is essential for the adequate treatment and reduction of complications.

Authors: Peixoto Victor , Machado Fernando
Published: May 2023

Introduction: Fever is one of the most common complaints seen in a pediatric appointment. Although this, many physicians and parentes' atitudes are taken soonly because they have too many misconceptions and concerns about fever. Among these attitudes, physical cooling methods are common. Objectives: the aim of this study is showing what is disseminated by medical literature about cooling methods in management of fever, its benefits and harms. Methods: its a literature integrative review about non chemical management of fever. The authors searched the Medline trials register and a free search to find others studies not published in that digital platform with the question: Whats is the value of non chemical fever management? Results: It was included 25 studies met the inclusion criteria. Discussion: there are many conflicting results showing or not showing benefits in the fever management with physical methods. Much of them show benefits only in the first minuts after cooling. Several conflicting results must be due the methodological problems. Conclusions: Currently, there is no definitive answers about advantages and disadvantages in fever management by using physical methods, considering risk and benefits.

The process by which executives unlearn their attachments in order to facilitate change
Authors: Rautenbach Rene , Sutherland Margie , Scheepers Caren B
Published: May 2023

Unlearning an attachment has become a critical change competence for executives. Although attachment behaviour in the workplace is ubiquitous, there is a scarcity of empirical research on the processes executives follow in order to release their dysfunctional attachments to systems, routines, ideas, divisions and certain members of staff. By unlearning attachments, executives can embrace new concepts, methods and processes and thereby enable their organisations to be more competitive. This qualitative research investigated executivesâ€™ experiences of unlearning an attachment, through the pre-unlearning, unlearning and post-unlearning phases. A de jure model was formulated from concepts that emerged during the literature review and this model was the basis of in-depth interviews with 10 change experts and 10 executives who had unlearned attachments. The executives and change experts shared real-life experiences during each of the unlearning phases. The findings informed a de facto model of the experiences of executives unlearning their attachments. This process model makes a theoretical contribution by depicting the major types of attachments, influences on, processes of, actions required by and outcome of the executivesâ€™ unlearning. The model should contribute to change practitionersâ€™ facilitation of executivesâ€™ unlearning processes and executivesâ€™ insights into their own attachments.
Development of a measure for perceived employment relationship quality (PERQ)
Authors: Potgieter Willem , Olckers Chantal , Ehlers Lukas
Published: May 2023

Studies have shown that employees react negatively towards negative supervisory behaviour. Therefore, a questionnaire that could measure the quality of various aspects of the employment relationship could be a useful tool for managing and promoting healthy employment relationships. In the light of this, the aim of this study was to develop a questionnaire that measured the perceived quality of the employment relationship from the employeeâ€™s perspective. A quantitative cross-sectional survey was conducted on a non-probability convenience sample of 248 employees from various organisations and sectors in South Africa. Although a 39-item questionnaire was developed across four theoretical dimensions, namely trust, fairness, good faith and justice, the analysis revealed that only two dimensions, labelled social factors and compliance factors and measured by 20 items, were sufficient to measure the desired construct. This questionnaire, which measures the perceived employment relationship quality, could be used as a diagnostic tool by management and HR professionals to determine the state of supervisory relationships in an organisation, and to address any problems brought to the fore, thereby avoiding turnover costs related to negative workplace relationships.

Psychological career resources as predictors of employeesâ€™ job embeddedness: An exploratory study
Authors: Ferreira Nadia , Coetzee Melinde
Published: May 2023

Managers and human resource practitioners concerned about retaining valuable staff members need to recognise how peopleâ€™s psychological career resources relate to their perceptions of job embeddedness in the organisation. The aim of the study was to determine whether employeesâ€™ psychological career resources (as measured by the Psychological Career Resources Inventory) significantly predict their job embeddedness (as measured by the Job Embeddedness Scale). A quantitative survey was conducted on a non-probability sample of employed black (92%) and female (71%) adults (N=355) at managerial and staff levels in the human resource management field. Correlational statistics and multiple regression analyses were used to analyse the data. The managerial career preference and self-esteem positively predicted the participantsâ€™ perceptions of sacrifice and links. Self/other skills and career directedness positively predicted perceptions of fit, sacrifice and links. Sense of career purpose negatively predicted perceptions of fit, links and sacrifice and the need for career venturing negatively predicted perceptions of sacrifice. In the South African employment equity context, the findings provide valuable information that can be used to inform career development support practices for the retention of black females in the human resource management field. The practical implications of the findings also add new insights towards negotiating the psychological contract and managing the employment relationship.
A reflection on the duty of mutual trust and confidence: Off-duty misconduct in the case of Biggar v City of Johannesburg revisited
Authors: Raligilia Konanani
Published: May 2023

The case of Biggar v City of Johannesburg Emergency Management Services (2011) 32 ILJ 1665 (LC) provides a critical analysis of the implied obligation of good faith and fair dealing in the context of off-duty misconduct. This paper examines the extent of the obligation upon the employer not to act without reasonable and proper cause, if the action is such as would be calculated or likely to destroy or severely damage the relationship of trust and confidence that exists between the employer and its employees. The paper further argues that failure by the employer to take the necessary steps to eliminate the off-duty racial abuse directed to the employee by the white co-workers resulted in the breakdown of trust and confidence in the workplace. Lastly, the paper examines the role that mutual trust and confidence play in protecting vulnerable employees by serving as a bulwark against illegitimate conduct on the part of the employer.

Published: May 2023

In the Littoral and East regions of Cameroon, the proliferation of the water hyacinth threatens the conservation of biodiversity. Indeed, its rapid multiplication asphyxiates fish and promotes malaria. Integrated pest management and many other methods have been used to eliminate this plant, but it persists, endangering the eco-systemic balance of marine environments. The efficient management of this plant remains a challenge. The aim of this study is to contribute to the implementation of a water hyacinth management protocol. The idea was to use this plant not only for natural fertilizer for soil improvement but also as energy production (biogas). The tests were carried out at the HIMA application farm in the Abong-Mbang area. Experiments were conducted using 60-Liters batch digesters. In all three sets of experiments, combinations of water hyacinth, cow dung and chicken droppings were used. For water hyacinth alone, an average production of 70 L of biogas was recorded. The best yield was obtained for the mixture of water hyacinth (5 kg), cow dung (1.5 kg) and chicken droppings (1 kg) at 1/4 dilution, i.e. 179 L/kg of substrate. The results obtained are encouraging and are being effectively used. This technology can therefore be applied in areas infested by Eichhornia crassipes for the production of energy, compost and control of water hyacinth proliferation.

Published: May 2023

The primary aim of this study was to investigate relationships between the muscular force in the isometric bench press and squat movements and the Wingate anaerobic test (WanT) results for the upper and lower body. Secondary purpose was to investigate possible correlations between the WanT and the explosive isometric force. Eighteen healthy male volunteer athletes (age: 23.37 ± 1.65, height: 178.37 ± 5.67, body mass; 76.69 ± 3.73) with at least 2 years of strength training participated in the study. During the two test sessions, one-repetition maximum (1-RM), isometric squat and isometric bench press tests and anaerobic power tests with Wingate anaerobic power and arm ergometer were performed. Results of the study showed a high degree of correlation between isometric squat (Squatiso) and lower body Peak Power and Average Power (r (14) = 0.766, p < 0.001 and r (14) = 0.690, p < 0.003 respectively). However, there was no significant relationship between Squatiso and Fatigue Index (FI) (p > 0.05). In isometric bench press, there was also a high level of correlation between upper body peak power and average power (r (14) = 0.620, p < 0.01 and r (14) = 0.749, p < 0.001 respectively). These data can be used to classify the power capabilities of the athletes and determining the training loads to be used in achieving the training goals. In addition, periodic measurements of the maximum power and strength performances of the athletes with field tests and laboratory test batteries according to the characteristics of the sports branch can also provide significant contributions to the coaches and researchers.

Core-Labeling Synthesis of Phenols
Authors: Lynch Colin , Zhang Yongliang , Levin Mark
Published: May 2023

The synthesis of isotopically labeled compounds with site-specificity is critical to the pharmaceutical and agrochemical fields. For reasons of synthetic accessibility, isotopic labeling methods have traditionally been restricted to the molecular periphery, even among potentially skeletal elements (C, N, O, etc.), limiting the classes and isotopomers of compounds one can prepare in labeled form. Here, we report a method that enables fast incorporation of carbon isotopes into a core atom of an aromatic compound, specifically the ipso carbon of phenols. Our approach relies on the synthesis of a 1,5-dibromo-1,4-pentadiene precursor, which upon lithium-halogen exchange followed by treatment with carbonate esters results in a formal [5+1] cyclization to form the phenol product. Using this strategy, we have prepared twelve different 1-13C labeled phenols with a variety of alkyl and aryl substitutions via dibenzyl carbonate as a carbon-13 synthon. Additionally, we show proof of concept for labeling of phenols with other carbon radioisotopes — we demonstrate dibenzyl carbonate synthesis from common carbon-14 sources, as well as phenol synthesis directly from carbon dioxide, providing a potential entry into carbon-11 radiolabeling.

Published: May 2023

Industrial Kraft black liquor from maritime pine was oxidised in aqueous, alkaline medium, under air, at 150°C, with or without CuO/TiO2 catalyst. The oxidation products were analysed by HPLC, elemental analysis, SEC, FTIR, NMR. The results showed the depolymerisation of lignin, the formation of phenolic compounds in low yields, with vanillin being the main phenolic compound, and the formation of aliphatic compounds in higher yields, with formic, succinic and tartronic acids being the main identified aliphatic compounds. The presence of the catalyst favoured the formation of phenolic and aliphatic compounds. Replacing Kraft black liquor by pure Kraft lignin as a starting material did not improve the performances of the catalytic oxidation, indicating that lignin purification may not be necessary under our conditions. Switching from a batch reactor to a fixed bed reactor, operating under similar conditions, did not increase the yields of oxidation products but did increase the productivity. This work demonstrates the potential of Kraft black liquor to produce a large panel of compounds, including phenolics, aliphatic acids and oxidised lignin, all of which valuable in chemical industry. For the first time, a catalytic process for the chemical valorisation of Kraft black liquor is presented.

The development of new powder feedstocks using nanoparticles (NPs) has the potential to enhance the functionality of as-built parts and overcome the limitations of current additive manufacturing (AM) techniques. This study investigated the impact of magnet microparticle feedstock modification by NPs on the microstructure and functionality of Nd-Fe-B-based permanent magnets made by suction casting. This casting method is known to at least partially mimic the melting and fast solidification steps inherent to metal powder-based AM techniques such as Laser Powder Bed Fusion. Two types of NPs, Ag, and ZrB2, were used, and their effects on grain size distribution and dendritic structure were evaluated. Ag NPs resulted in smaller, more uniform grain sizes and increased functionality, but only for loadings > 0.5 monolayers. ZrB2 resulted in uniformly distributed grain sizes at much lower mass loadings, with even more compact dendritic arms. The results show that feedstock powder surface modification with low melting point metal NPs can improve the microstructure and magnetic properties of permanent magnets produced by AM and highlight the potential of using NPs to develop new powder feedstocks for AM. With this, it provides insights for future research on optimizing materials for AM processes.
Theoretical Analysis of the Electronic Structure and Optical Properties of DNA-Stabilized Silver Cluster Ag16Cl2 in Aqueous Solvent
Authors: Häkkinen Hannu , Malola Sami , Matus Maria Francisca
Published: May 2023

DNA-stabilized silver nanoclusters with 10 to 30 silver atoms are by construction ideal candidates for biocompatible bright fluorescent emitters but their electronic structure is not well understood. Here, using density functional theory (DFT), we analyze the ground-state electronic structure and optical absorption of a bright NIR-emitting cluster Ag16Cl2 which is stabilized by two DNA strands of 9-base sequence 5’-CACCTAGCG-3’ and whose atomic structure was very recently confirmed to have two chlorides bound to the silver core. We are able to (i) unambiguously assign the charge of this cluster in aqueous solvent, (ii) analyze the details of silver–DNA interactions and their effect on the cluster charge, (iii) analyze the character of low-energy optical absorption peaks and the involved electron orbitals and make a first assessment on circular dichroism, and (iv) evaluate the suitability of various DFT exchange-correlation functionals via benchmarking to experimental optical data. This work lays out a baseline for all future theoretical work to understand the electronic, chiroptical and fluorescence properties of these fascinating bio-compatible nanostructures.
Control of wheeled platforms straight motions taking into account jerk restrictions under speeding-up from the state of rest
Authors: Nevliudov I. Sh. , Romashov Yu. V.
Published: May 2023

The generalized mathematical model of wheeled platforms straight motions on the ideal horizontal plane under speeding-up from the state of rest mode is proposed, and the controls satisfying the restrictions of motion jerks are find. The pure mechanical and electromechanical wheeled platforms are considered, as well as the computer simulations of the researched processes are made. The jerks restrictions are reduced to limiting the value of the wheeled platform acceleration time derivative. The proposed approaches are based on the holonomic systems mechanics and on the electromechanical analogies allowing to consider the different kinds of the wheeled platforms taking into account the electric on-board systems like the drive electric motors and the control systems by using the Lagrange equations of second kind. The examples of the proposed approaches using to define the controls satisfying the jerks restrictions under speeding-up from the state of rest are considered for the pure mechanical and electromechanical wheeled platforms. It is obtained the inequality allowing to chose the instantly supplied driving mechanical couple which will provide the admissible jerks of the motion of the wheeled platform under speeding-up from the state of rest. It is shown that the rolling friction and the viscous damping are the principal causes of the wheeled platforms jerks under speeding-up from the state of rest. It is obtained the inequality defining the voltage instantly supplied on the drive electric motors which will provide the admissible jerks of the motion of the electromechanical wheeled platform during speeding-up from the state of rest, and it is shown that the proposed general approaches are suitable for considering the different kinds of wheeled platforms. The computer simulations of the processes of speeding-up from the state of rest for the electromechanical wheeled platform are considered to show results correctness and to illustrate satisfying the restrictions of the motion jerks. The obtained results of the computer simulations are in the full agreement with the well-known fundamental property inherent for the wheeled platforms. The results for the jerks show that the maximum value of the jerk is really at the initial time as was suggested before, and it is shown that the jerks values at the initial time obtained by using the computer simulations are in full agreement with the theoretically defined correspondent exact values. The big jerks of the considered electromechanical wheeled platform are due to the voltage instantly supplying on the drive electric motors at the initial time, and it is understandable that limiting of such instantly supplied voltage value cannot provide any wished small jerks. The smooth time depending for the voltages supplying on the drive electric motors are required to provide any wished small jerks of the electromechanical wheeled platforms.
The explicit form of the switching surface in admissible synthesis problem
Authors: Korobov V. I. , Vozniak O. S.
Published: May 2023

In this article we consider the problem related to positional synthesis and controllability function method and more precisely to admissible maximum principle. Unlike the more common approach the admissible maximum principle method gives discontinuous solutions to the positional synthesis problem. Let us consider the canonical system of linear equations $\dot{x}_i=x_{i+1}, i=\overline{1,n-1}, \dot{x}_n=u$ with constraints $|u| \le d$. The problem for an arbitrary linear system $\dot{x} = A x + b u$ can be simplified to this problem for the canonical system. A controllability function $\Theta(x)$ is given as a unique positive solution of some equation $\Phi(x,\Theta) = 0$. The control is chosen to minimize derivative of the function $\Theta(x)$ and can be written as $u(x) = -d \text{ sign}(s(x,\Theta(x)))$. The set of points $s(x,\Theta(x)) = 0$ is called the switching surface, and it determines the points where control changes its sign. Normally it \mbox{contains} the variable $\Theta$ which is given implicitly as the solution of equation $\Phi(x, \Theta) = 0$. Our aim in this paper is to find a representation of the switching surface that does not depend on the function $\Theta(x)$. We call this representation the explicit form. In our case the expressions $\Phi(x, \Theta)$ and $s(x, \Theta)$ are both polynomials with respect to $\Theta$, so this problem is related to the problem of finding conditions when two polynomials have a common positive root. Earlier the solution for the 2-dimensional case was known. But during the exploration it was found out that for systems of higher dimensions there exist certain difficulties. In this article the switching surface for the three dimensional case is presented and researched. It is shown that this switching surface is a sliding surface (according to Filippov's definition). Also the other ways of constructing the switching surface using the interpolation and approximation are proposed and used for finding the trajectories of concrete points.

The purpose of the article is to understand the phenomenon of economic turbulence in terms of its impact on the Russian economy. The article determines that economic turbulence finds its expression in rapid, tolerable fluctuations in the key parameters of entrepreneurial activity, which ultimately leads to significant disproportions both in the economy of individual companies and countries and in the global economy in general. It is turbulence in modern conditions that is considered one of the key factors in the cyclical development of social systems, determining the vectors of their movement. Turbulence forms the highest level of economic system instability, which is accompanied by high risks in various areas and can cause the destruction of economic systems, which is its main danger. It is indicated that the unpredictability and chaotic nature of economic processes in Russia gives reason to say that the country has entered a period of economic turbulence. The article provides a situational analysis of the phenomenon of economic turbulence using the methodology of institutionalism and positivism, and the method of statistical assessments was also used in the process of research. As a result, the author found that at present Russia has lost 20% of its oil exports, with a general decline in world oil prices; there is also a process of establishing a flow of prices for Russian oil products, which will be differentiated depending on the type of oil products; under these conditions, the Russian budget is becoming increasingly dependent on the level of oil prices, despite the fact that the demand for Russian gas in Europe is declining; sanctions and recession in the economy have dropped the demand for transport services; Russian aviation, meanwhile, was engulfed by a record string of accidents after Western sanctions that interfere with normal and timely repairs and navigation; A contradictory situation is developing in the labor market, where official data stubbornly fixes lows in unemployment, despite the fact that 33% of Russian companies have reduced their staff. Under these conditions, the author considers it necessary to use the mobilization potential of Russia, the country needs to mobilize financial resources, unite the people around ideology, mobilize human and intellectual potential, introduce a mechanism of responsibility for the results of the work of all leaders and authorities. The novelty of the study axiomatizes the conclusions about the consideration of economic turbulence as a subject of economic theory. The author concludes that the growth of economic turbulence in the world actualizes the formulation of the theory of causes based on actual reality.

A Critical Approach to Student Agency Discourse: Focusing on ‘Burnout Society’ and the Concept of Governmentality
Authors:   Koreanisch-Deutsche Gesellschaft Fuer Erziehungswissenschaft, Ko Dahyun , Cho Sang-Sik
Published: May 2023

This study aims to critically analyze ‘student agency’ which is presented as a key competency in future education, through the lenses of Han’s ‘Burnout Society’ and Foucault’s governmentality. Student agency is an ability for students to act independently in and out of school. However, although discourses on student agency become crucial for future education, reflective or critical approach to the concept is scarcely found. If most researchers simply try to utilize the concept for future education without any critical reflection, pathological issues in education (e.g., student depression) would remain unsolved.
Foucault’s concept of governmentality helps more comprehensive understanding along with Han’s argument. Governmentality is a systematic social mechanism that activates power by controlling minds of individuals. In neoliberalism, governmentality deceives individuals by making them to orientate themselves towards ‘freedom to be normal.’ With Foucault’s idea, Han’s concept of self-exploitation is interpreted as an exploitation by formless power structure. For this concept, it is remarkable that power gradually hides its appearance and blurs a boundary between a subject and the power structure.
Student agency discourse, however, tends to be insufficient with the reflection of a relationship between learners and power structure focusing only on methodological aspects by highlighting student agency as a solution for future education. The issues which may be occurred by this are as follows. First, this may repeat the argument of pedagogy in the Enlightenment era by supporting students’ autonomy and rationality. Second, the uncertainty of future could belittle a discourse on the role and duty of education. Third, student agency can be misunderstood as a panacea for future education when it is interpreted as a competency in lifelong learning.

Objetivo: determinar la concordancia en el diagnóstico y clasificación de la retinopatía diabética utilizando imágenes de fondo de ojo de campo ultra amplio, comparando los sistemas Optos® y Clarus 700®. Materiales y métodos: se realizó un estudio comparativo, descriptivo, prospectivo y transversal en el que se incluyeron 144 ojos de 77 pacientes (41 hombres y 36 mujeres) para con una confianza del 95%, estimar el coeficiente de concordancia K (kappa). --- Resultados: el coeficiente Kappa de Cohen obtenido fue de .846, que se traduce como una concordancia muy buena entre los sistemas Optos® y Clarus 700® en el diagnóstico y clasificación de la retinopatía diabética utilizando imágenes de fondo de ojo de campo ultra amplio. --- Conclusiones: ambos sistemas de imagen de fondo de ojo de campo ultra-amplio mostraron ser similares en el diagnóstico y clasificación de la retinopatía diabética; sin embargo, Optos® permitió imágenes de fondo de ojo más amplias que Clarus 700®; mientras que Clarus 700® produjo menos artefactos y proporcionó imágenes más detalladas del fondo de ojo. No se tiene registro de estudios previos que comparen ambos sistemas de campo ultra amplio que se hayan realizado en México, lo cual permite utilizar la información obtenida como base para estudios posteriores. Palabras clave. Diabetes mellitus, retinopatía diabética, sistemas de imágenes retinales de campo ultra amplio.
Stewart’s Theorem and Median Property in the Galilean Plane
Authors: Açıkgöz Abdulaziz , Sönmez Nilgün
Published: May 2023

Galilean plane can be introduced in the affine plane, as in Euclidean plane. This means that the concepts of lines, parallel lines, ratios of collinear segments, and areas of figures are significant not only in Euclidean plane but also in Galilean plane. The Galilean plane 𝐺2 is almost the same as the Euclidean plane. The coordinates of a vector 𝑎 and the coordinates of a point 𝐴 (defined as the coordinates of 𝑂𝐴, where 𝑂 is the fixed origin) are introduced in Galilean plane in the same way as in Euclidean geometry. The galilean lines are the same. All we need add is that we single out special lines with special direction vectors in Galilean plane. We should attention that these two types of galilean lines cannot be compared. The difference between Euclidean plane and Galilean plane is the distance function. Thus, we can compare the many theorems and properties which is included the concept of distance in these geometries. The theorems and the properties of triangles in the Euclidean plane can be studied in the Galilean plane. Therefore, in this study, we give the Galilean-analogues of Stewart’s theorem and median property for the triangles whose sides are on ordinary lines.
Board Gender Diversity and Firm Performance: Evidence from Family-Owned Firms in India
Authors: Saha Rupjyoti , Maji Santi Gopal
Published: May 2023

This study investigates the impact of board gender diversity (BGD) on firm performance (FP) for family-owned Indian firms. To do so, this study selects a sample of the 75 top-listed family-owned firms for a period of 5 years. For empirical analysis, the study used appropriate panel data models. For robustness, the three-stage least square (3SLS) model was used. The findings obtained from panel data models reveal a significant positive impact of BGD in terms of its different measures on FP after controlling corporate governance and firm-specific characteristics. Such results are further substantiated through the 3SLS model. This study provides novel evidence on the impact of BGD in terms of its diverse constructive measures on FP for family-owned firms in the Indian context, thereby extending the ongoing debate about the outcomes of the mandatory gender quota on board for an emerging market.
Factorial structure of the determinants of tourist stay in the biosafety protocol before Covid-19
Authors: García Lirios Cruz
Published: May 2023

The reactivation of tourism had been studied from the influence of the habitus of transfer and stay, but with the health contingency this process was mediated by the information of the places with biosafety protocols. The objective of the present work was to contrast a model of the determinants of stay, considering the mediating variables of the information. A confirmatory, psychometric and cross-sectional study was carried out with a selection of 100 students from a public university in central Mexico. A factorial structure was found that explained 61% of the variance and established the intention to transfer as a predictor, suggesting the extension of the work towards biosafety protocols.

This study explores students' environmental attitudes when participating in science learning that applies tools integrated with the local potential of Central Lombok tourist destinations. This research is descriptive. This research was conducted at junior high school MTsN 3 Lombok Tengah. The research subjects were 28 students from one of class VII. The tools used consist of lesson plans, teaching materials, and assessment instruments that integrate the local potential of Central Lombok tourist destinations. The instruments used are interview guidelines with teachers, observation sheets of learning implementation, and environmental attitude questionnaire instruments validated by expert validators. The results of this study indicate that the average value of environmental attitude in each indicator includes; (a) understanding norms about protecting the environment, which obtains a score of 60 which is included in the good category, (b) knowing the environment that must be maintained obtains a score of 50 which is included in the fairly good category, and (c) demonstrating a commitment to protecting the environment obtains a score of 59 which is included in the good category. These results indicate that using learning tools integrated with the local potential of Central Lombok tourist destinations in the sub-material Interaction of Living Things with the environment for class VII can train students' environmental attitudes.

Análise do novo visto japonês para quarta geração e seus efeitos na população nipo-brasileira
Authors:   , Lima Leonardo Teixeira Miyamoto de
Published: May 2023

Podemos dizer que as imigrações foram os pontos de início na criação de países, não somente, os fundando como também se tornando laços entre os mesmos. Como país, o Brasil ganhou não somente uma mão de obra agrícola, mas também uma estreita relação com o Japão visto os descendentes que nasceram em nossa pátria. Assim com os anos se passando, agora estamos em uma época onde nossos descendentes estão regressando ao país asiático. Com a necessidade de mão de obra e somado a baixa natalidade no país, o Japão tem buscado por trabalhadores nas colônias estrangeiras, sendo o Brasil uma das maiores delas. Com exatos três vistos de descendências até então, este ano está previsto o visto da quarta geração. Sendo algo totalmente novo e que abrange uma vasta população, os vistos têm chamado à atenção dos descendentes, seja por questões financeiras ou de estudo. O trabalho então propõe aqui abordar brevemente a trajetória da imigração passando pelos vistos e chegando aos principais objetivos do visto vigente e se o mesmo consegue suprir os sonhos e propósitos que os descendentes procuram na terra do sol nascente.
