Authors: Quintana Lucirlene Maciel Cavalheiro , De Jesus Thaís Vieira
Published: March 2023

A produção de leite tem grande relevância econômica no agronegócio brasileiro e representa uma participação importante no PIB agropecuário. A propriedade rural em estudo, localiza-se no município de Jaraguari-MS, onde desenvolve a leiteira como atividade principal de suas receitas operacionais. O objetivo geral deste artigo foi analisar a rentabilidade na pecuária leiteira de uma propriedade rural de pequeno porte situada no município de Jaraguari - MS. Foram definidos como objetivos específicos avaliar o desempenho técnico-econômico da atividade leiteira por meio dos índices técnicos de produção média por vaca em lactação/dia, produção média diária pelo total de vacas do rebanho; identificar as receitas, os custos e as despesas da pecuária leiteira na propriedade rural no período de setembro de 2019 a agosto de 2020; calcular o resultado econômico do ponto de equilíbrio e da margem de segurança utilizando a contabilidade de custos como ferramenta de auxílio à tomada de decisão. O trabalho caracteriza-se como bibliográfico, documental e estudo de caso, com abordagem qualitativa, aplicada e descritiva. A coleta dos dados realizou-se por pesquisas semiestruturadas de visitas a campo e informações disponibilizadas pelo produtor. Através da tabulação e análise das informações, avaliou-se os índices técnicos de produção, apurou-se a receita, os custos e as despesas, calculou-se o ponto de equilíbrio (em valor monetário e quantidade) para obter-se a margem de segurança. Portanto, o estudo mostra a realidade de um pequeno produtor rural, onde a rentabilidade da produção de leite é baixa e necessita de aperfeiçoamentos em sua gestão e planejamentos financeiros.
O conceito de campo de Fetch aplicado ao reservatório da UHE de Itaipu
Authors: Luchetti Marcelo Rosolem , Dieter Jonathan
Published: March 2023

Em estudos envolvendo corpos de água continentais como lagos, reservatórios e estuários, o fetch é obtido pontualmente com base na direção do vento e no formato das margens. Como se constitui em um conceito geométrico, sua determinação é fortemente condicionada pelo formato irregular e geralmente dendrítico do entorno do corpo de água. O fetch é comumente utilizado para estimar fenômenos como ondas e seiches gerados pelo vento em corpos de água. Como estes são bem representados por um campo bidimensional, decidiu-se pelo tratamento do fetch como um campo de modo a possibilitar abordagens bidimensionais. Assim exposto, esta comunicação científica propõe ampliar o conceito de fetch através da representação bidimensional via processamento automatizado. Para tanto foi desenvolvido um programa computacional em linguagem LISP denominado ONDACAD. O modelo apresentado permitiu, além da distribuição do fetch, a determinação segura dos valores máximos para cada direção no reservatório da Usina hidrelétrica de Itaipu.

In the recent decade, single-shot ultrafast optical imaging by active detection, called single-shot active ultrafast optical imaging (SS-AUOI) here, has made great progress, e.g., with a temporal resolution of 50 fs and a frame rate beyond 10 trillion frames per second. Now, it has become indispensable for charactering the nonrepeatable and difficult-to-reproduce events and revealing the underlying physical, chemical, and biological mechanisms. On the basis of this delightful status, we would like to make a review of SS-AUOI. On the basis of a brief introduction of SS-AUOI, our review starts with discussing its characteristics and then focuses on the survey and prospect of SS-AUOI technology.
Lifetime physical activity and the cognitive condition of adults. Research of three independent groups of Polish adults
Authors: Szepietowska Ewa Małgorzata , Dąbal Alicja
Published: March 2023

One of the typical symptoms of aging is the deterioration of the functioning level in specific cognitive areas. A significant number of research reports suggest that physical activity over the life course may be conducive to maintaining cognitive efficiency in late adulthood and old age. Aim: Research was undertaken to investigate whether the level of the reported physical activity over the life span can determine cognitive performance in the selected areas in adults. Material and methods: The material was collected from 2019. Individuals aged 40+ were invited to participate in the study. Three independent assessments were carried out in separate groups of subjects (Group 1: N = 120; Group 2: N = 90; Group 3: N = 60). A total of 270 individuals participated in the study. A questionnaire designed by the authors was used to assess the intensity of physical activity. The MoCA test, WAIS-R PL subtests, verbal fluency tests, BDI-II and DEX-S were applied to assess cognitive and emotional functions. In Group 3 the Trail Making Test was also used. Results: Linear regression analyses showed significant similarities across groups. Higher age was associated with lower cognitive performance, whereas higher level of physical activity reported by the subjects corresponded to better efficiency in the specific cognitive competencies. Physical activity was the main determinant of cognitive performance in the youngest study group (aged between 45 and 60 years). Conclusions: Older age promotes cognitive decline. Higher level of the reported lifetime physical activity positively affects cognitive functioning at later stages of life. Physical activity may play a compensatory role and support cognitive competencies in older adults, especially in operations involving executive functions. However, the relation between physical activity and cognitive performance varies depending on the age of the subjects. The older a person gets, the more important the age factor becomes for the level of cognitive functioning, and the observed impact of physical activity decreases.
Family (systemic) factors influencing life standards and health of working class
Authors: Litwińska-Rączka Katarzyna
Published: March 2023

Adults function simultaneously in several areas, among which the most important ones are family and work. In these areas, they meet their needs and experience satisfaction as long as they are able to use them in a mature way. This, in turn, is largely conditioned by previous experiences–those from childhood. The article is a reflection on systemic factors affecting the quality of life and personality maturity of adults. Almost all of us are brought up in families. From the family we take behavior patterns, experience patterns and personality traits. Our traits, schema, and patterns of behavior affect our quality of life and maturity. Therefore, it is important that they are optimal and functional. The author uses the knowledge and research in the field of family psychology and family therapy. The definitions of a mature personality according to Irwin Yalom (therapist) and the concepts of a positive quality of life are adopted. Numerous Polish and foreign studies are cited to show the relationship between professional success and life satisfaction and the personality traits previously shaped in the family. The author presents the characteristics of families that are conducive to the maturity of their members. Special attention is drawn to the importance of the marital relationship and the sense of happiness of the spouses as the factors determining the functioning of the whole family and affecting it so that it becomes either healthy or dysfunctional. The author emphasises the characteristics of families related to their structure, communication, system boundaries and self-esteem. She writes about the dynamic balance of the family and the freedom to express one’s own thoughts and feelings as the key features of a proper family system. When children experience family characteristics which are conducive to a mature personality, health and a sense of happiness, then, as adults, they succeed in various fields of life. Therefore, it seems extremely important to reflect on systemic (family) factors affecting the quality of life and human maturity.
Promotion of the Catholic family in crisis situations. Analysis taking into account the canonical order
Authors: Biały Stanisław
Published: March 2023

The concept of a Catholic family can be explained by its membership in the Church, as well as by its relationship with the sacraments (with God's grace), etc. Its vocation is the community of life of a woman and a man (communio personarum), formed by a sacramental marriage and having children. Such a community enjoys normative (canonical) care and promotion in the legal order of the Catholic Church. This is particularly important when the Magisterium of the Church comes into contact with gender ideology, or secular culture in general (and this is the status quo of the issue). The author of the analysis indicated the most important elements that (in his opinion) are of particular importance for this confrontation. He analyzed in particular those aspects which in the doctrine of the Church are called crisis ones. The aim was to show in what direction the canonical defense of faith, morality, spiritual good, etc. goes (or should go, from the point of view of Catholic ethics). It was about situations where a party practicing the Catholic faith wants to enter into marriage with an unbaptized person or with a notorious apostate faith, i.e. a formal apostate, etc. Here, the Church, apart from the traditional guarantee of faith, demands something more, being (due to the emerging threats of losing faith by a practicing nupturient) reluctant to mixed relationships and similar.

Published: March 2023

Since the experience of love and close relationships is one of the most important aspects of human life, man defines his existence by diverse relationships. The congruence of expected and received forms of love transmission is important. This study verifies whether there is a relationship between the forms of showing love and the sense of loneliness in a group of young adults. Methods: The study used the Forms of Expressions of Love Questionnaire (FOREM) designed by M. Rys and colleagues, and the R-UCLA Loneliness Scale, a Polish adaptation of Russell, Peplau and Cutrona’s tool, developed by M. Kwiatkowska, R. Rogoza and K. Kwiatkowska. The survey with the participation of 73 women and 73 men was conducted online. The youngest person was 18 years old, and the oldest –34 (Max = 34). The average age of the subjects was just under 24 (M = 23.99). Results: The results of correlation analysis with the application of Kendall’s Tau-b coefficient proved to be statistically significant for the associations of all subscales of feelings of loneliness and the overall score of this variable, with the discrepancy between expected and received forms of love in terms of help and time. All statistically significant correlations were positive, meaning that the greater the discrepancy between the expected and received form of love, the higher the sense of loneliness. The strongest statistically significant correlation was that of the dimension of help with the dimensions of belonging and affiliation (Tau-b = 0.247; p < 0.01) while the weakest was the correlation of the dimension of time with the dimension of social others (Tau-b = 0.131; p < 0.05). Conclusions: The results of the study indicate that young adults do not experience love in the expected forms regarding affectionate touch, help from the other person and time devoted to them. The greater the discrepancy between the expected and received forms of love, the higher the feelings of loneliness among young adults.

Gum Su-hyun(1919-1992) who composed the song , was born during the colonial era and worked as a musician, education administrator, and music media publisher during the liberation period and the formation of the national system. These activities served as a source of writing. His literary activities can be confirmed through music related books, newspapers and magazines. Literary activities started from media publication. After that, he published a series of columns in the newspaper media to criticize the social situation. and He expanded his position by leading public opinion in Monthly Music published by him. He continued his own writing by publishing everyday essays, professional commentaries, and current affairs criticism in various magazines. As a result of analyzing Gum Su-hyun’s literary activities, it is that the writings containing his critical thoughts reflecting the reality of the time were dominant. In this respect, Gum Su-hyun’s writings can be collectively referred to as ‘critical writing’. His critical writing embodies a kind of sense of duty, which he must do as an educator and musician who has gone through turbulent era.
In this study, Gum Su-hyun’s literary activities were reviewed and his critical writing was examined. Gum Su-hyun actively intervened in the reality of the times through critical writing and revealed her own musical, social, and historical perspectives. Critical writing contains Gum Su-hyun’s philosophy and attitude, which critically views the exploration of national identity, the love of Hangeul, the realization and spread of the value of our style’s music, and the reality of popular music. These consciousness and attitudes were expressed in own critical writings, starting from sincere consideration for our style’s thing.

Structure of personal values and corruption: An experimental analysis of decisions leading to accepting or rejecting bribery
Authors: Roth Eric , Sahonero Guillermo , Rodriguez Andrés
Published: March 2023

Corruption is a legal and moral contravention that generates great concern among nations due to its erosive effects on economic growth, democracy, governance, social equity and the integrity of culture. Therefore, it is necessary to know more about the multiple variables that produce and maintain this phenomenon. This article reports the results of an experimental investigation that sought to provide elements of judgment on the influence of the structure of personal values on the willingness to bribe. For this, 12 couples of young university students of both sexes interacted through a game that simulated a relationship between a corrupter and a corruptible agent, with the help of a real-time communication system, mediated by an online platform, which allowed instant and bidirectional interaction. The couples were randomly constituted and played with each other under double blind. However, the interacting members of the dyad could share values or vary in their axiological structure in such a way that, while one of them could manifest anti-corruption principles, the other's commitment was not so obvious. The results confirm the importance of the axiological structure of people in the facilitation or containment of the corrupt behavior. This article also reflects on the theoretical connotations of the relationships shown.

Published: March 2023

This study uses a portion of the learner data from Learning management system(LMS) to find factors that affect academic achievement. In addition, this study tried to suggest a method to apply this learning analysis to English education. For this purpose, the LMS data for (1) lectures during the 4th semester (September 2020~June 2022) in the ‘online class environment’ due to COVID-19 and (2) classes in the 2nd semester in 2022 conducted as ‘blended learning’ classes was collected and analyzed. The main results are as follows. In the ‘online learning environment’, it was found that there was a significant positive correlation between the access frequency and grades by LMS content and the frequency of access to class lecture videos, notices and assignments had a significant effect on learners’ grades. In the ‘blended learning environment’ the results of the correlation analysis showed that there was a significant positive correlation between the access frequency of announcements and videos and grades.
However, in the results of the regression analysis, there were no variables that affected grades. This study is meaningful in that it investigated the relationship between the frequency of access to each content and academic achievement in order to identify more accurate variables.
Quantitative evaluation of implied open-circuit voltage after metal electrode deposition on TiO
x
/Si heterostructures by photoluminescence imaging: impact of metallization on passivation performance

Published: March 2023

The degradation of surface passivation performance by metallization is a challenge in realizing highly efficient crystalline Si solar cells that use novel carrier-selective contacts. Here, we report on a simple method to study the effect of metallization on passivation of titanium oxide (TiO
x
)/Si heterostructures. We investigated the relationship between the implied open-circuit voltage (iV
OC) and the photoluminescence (PL) intensity imaging of solar cell precursors before metallization. Based on the relationship obtained, the change of the iV
OC before and after metallization on the TiO
x
was evaluated quantitatively. The results showed that the iV
OC predicted by the PL measurement decreases by 23–104 mV after metal deposition and shows a good agreement with the measured V
OC in the finished solar cells. These results demonstrate that the iV
OC evaluation by PL measurement provides a good prediction of the V
OC after metallization, which is useful in analyzing the passivation degradation induced by metallization.

Published: March 2023

May 2023 marks the 125th anniversary of Maria Osipovna Knebel’s birth. On the eve of this anniversary, Natalya Alekseevna Zvereva, Knebel’s student, outstanding theatre teacher, professor at the Department of Drama Directing at GITIS, Honored Art Worker of the Russian Federation, and Ph.D., shared her memories of working together with Maria Osipovna in 1971. It happened during the production of the play by A. N. Ostrovsky, “Talents and Admirers,” at the Moscow Academic Theatre named after Vl. Mayakovsky. Maria Knebel called this performance the most beloved of all the productions staged by her. Using the example of Knebel’s work on this production, the article traces some unique features of her rehearsal and pedagogical approach. Her method of work was based on an effective analysis of the play. She obtained this last brilliant discovery of K.S. Stanislavsky (as Knebel herself described it) directly from him. Maria Knebel devoted many years of her life to this method’s development, along with its introduction into theatrical practice and pedagogy.

The power of images and the role of social media in Black Lives Matter’s social justice demands
Authors: Picarella Lucia
Published: March 2023

The proliferation of connections between the digital world and social activism shows that social media have become fundamental tools for collective action strategies. This article analyses the case study of Black Lives Matter, a movement that is expressing strong potential at a social and cultural level. The aim of this article is to observe the key role played by social media and images on the strengthening of identity, on the (re)signification of collective values, on the radicalisation of the action of the transversal demand for social justice. The previous study on the organisational and structural characteristics of the movement, and their intertwining with the maximisation of the possibilities offered by digital ecosystems, highlights in our conclusions the creation of a new social narrative that has modified perceptions and behaviour, and the strong pervasiveness of #BLM at a socio-cultural level opens up interesting possibilities in terms of pressure on the political-institutional system, political legitimisation and the creation of a structured dialogue between the establishment and civil society.

A presente contribuição tem como objetivo descrever e analisar a atuação da União Africana na estabilidade da África através do instrumento da APSA, partindo de uma pesquisa qualitativa, através da análise historiográfica de instrumentos políticos e jurídicos, e estudos de caso das missões de paz da UA de 2003 a 2015. Concluiu-se que a Organização atua nas regiões de disputas, mas muitas vezes precisa da ajuda da ONU ou de financiamento internacional, por não possuir recursos suficientes para o sucesso das operações. A Organização dedica-se à solução dos conflitos regionais africanos, apesar de alguns pilares da Arquitetura de Paz e Segurança ainda estarem em processo de solidificação.

نظرية العامل النحوي و قواعد النّحو التّحويلي - دراسة مُقارِنة
Authors: الأحمدي سناء
Published: March 2023

يتجه اهتمام هذه الدراسة إلى نظريةٍ أساسيةٍ في الدراسات النحوية القديمة؛ إذ لولاها لما كانت القواعد ولا الإعراب, ولأهمية هذه النظرية فقد شغلت العلماء قديمًا وحديثًا, ووقف منها البعض معارضًا لها؛ إنها نظرية العامل التي وُضعت أصولها منذ عهد الخليل بن أحمد, وسيبويه.

     تكمُن مشكلة الدراسة في قصور نظرة بعض العلماء القدماء والمحدثين إلى نظرية العامل, فكثُر الهجوم عليها, وظهرت العديد من المحاولات التي تسعى لهدمها, والاتجاه إلى غيرها من النظريات الحديثة, فتحاول الدراسة إثبات أنّ معظم النظريات الحديثة, ماهي إلا امتداد لنظرية العامل النحوي, فتسعى الدراسة إلى إبراز أهميّة نظرية العامل ودورها في فهم أركان الجملة, والجمع بين التراث النحوي والنظريات الحديثة, ببيان نقاط الالتقاء بين النحو العربي والنحو التحويلي, وسيكون ذلك باتباع المنهج الوصفي للوقوف على النظريتين وتحليليهما, كما تتبع الدراسة المنهج المقارِن الذي يهتم بتحديد أوجه التشابه بين النظريتين .
