Authors: Salma Nabila , Alsa Asmadi
Published: December 2023

The purpose of this research is to empirically examine the role of self-regulated learning and student engagement in academic activities in math achievement. The research design used is a correlational survey. The subjects of this study are students at Madrasah Aliyah Negeri in Yogyakarta. The research sample was selected using a proportional stratified random sampling technique, with a total of 96 students. Math achievement was determined from students' daily evaluations, and data were collected using a self-regulated learning scale and a scale of student engagement in academic activities. Data were analyzed using multiple regression analysis. According to the findings, self-regulated learning and student engagement in academic activities significantly predict math achievement. Both self-regulated learning and student engagement in academic activities have a positive impact on math achievement. The combined contribution of self-regulated learning and student academic engagement to mathematics achievement is 37.1%. Self-regulated learning contributes more (17.39%) than academic engagement (19.77%) to mathematics achievement. This study recommends that students, teachers, and parents pay attention to self-regulated learning and student engagement factors.

Authors: Wahyuni Sri , Agustina Hellya , Munthe Ricca Angreini
Published: December 2023

The results of previous research have found that academic burnout occurs at all levels of education, including universities. Academic burnout is a syndrome characterized by emotional exhaustion, depersonalization, and a lack of confidence in students' abilities. It can be influenced by various variables, such as personality, well-being, and demographic factors. This research aims to examine the relationship between personality and academic burnout among college students while also exploring the role of psychological well-being as a mediator and demographic factors as a moderator, using a correlational design. This design allows for the simultaneous collection of data from many individuals. We recruited 522 undergraduate students to participate in an online survey and used the Maslach-Student Burnout Inventory (MSBI), NEO Five-Factor Inventory (FFI), and Psychological Well-being Questionnaire for measurement. For data analysis, we used SPSS  version 25 and IBM SPSS AMOS  version 24 to determine the mediation-moderation effect and tested the factor analysis of the proposed model. This research found a relationship between personality and academic burnout, with extraversion, agreeableness, conscientiousness, and openness to experience being associated with low academic burnout, while neuroticism was associated with high academic burnout. Furthermore, the level of student psychological well-being was found to mediate the correlation between personality and academic burnout. Therefore, this study recommends that students, teachers, and parents pay attention to the importance of psychological well-being.

Authors: Pradesa Hafid Aditya , Tanjung Hasrudy , Agustina Iin , Salleh Nik Sarina Nik Md
Published: December 2023

Educational institutions, such as Islamic high schools, face challenges in managing teacher performance, particularly in promoting proactive behavior. This study aims to explore the impact of an ethical work climate characterized by principles of caring, instrumental independence, service, rules, and codes, as well as perceived organizational support (POS), on teachers' proactive behavior in Islamic senior high schools. The study includes a one-month convenience sampling period, with 104 teachers from Medan, North Sumatra, participating as respondents. Primary data was collected through the perceptions of the respondents and analyzed using a PLS-based SEM. Findings highlight that an ethical work climate has a greater influence on teachers' proactive behavior compared to POS. While perceived organizational support remains important, the unique cultural and religious context of Islamic schools may elevate the significance of an ethical work climate. Teachers may perceive ethical guidelines and values as integral to their role and mission within the Islamic educational setting, leading to a more profound impact on their proactive engagement compared to the general perception of organizational support. The study concludes that the ethical work climate in Islamic senior high schools plays a crucial role in influencing teachers' proactive behavior, emphasizing the importance of fostering and maintaining an ethical work environment to support teachers in their professional endeavors.

Published: December 2023

Background: Vacuum suction drainage is an obligatory practice for long past following mastectomy for breast cancer. But recent studies are showing that the pressure of the vacuum suction drain is of value in determining the volume of seroma formation and thereby the drain indwelling time, duration of hospital stays and patient morbidity. Half vacuum suction may be of greater value in this regard comparing full vacuum suction drainage. Objectives were to assess and compare the clinical outcome of half versus full vacuum suction drainage following modified radical mastectomy for breast cancer.
Methods: Forty patients of histologically proven breast cancer had been chosen purposively and systematically randomized in two equal groups. Group A with half vacuum suction (device was squeezed up to half of its vertical length) and group B with full vacuum suction (device was squeezed to its maximum). The outcome measured were postoperative drainage, drain indwelling time and post-surgery length of hospital stay.
Results: Patients having half vacuum suction had a significantly reduced mean total drainage volume (364.25±128.52 ml versus 822.00±251.30 ml), drain indwelling time (5.50±1.32 days versus 9.05±1.90 days) and post-surgery hospital stay (7.15±2.58 days versus 10.25±2.55 days) in comparison to the full vacuum suction group. No significant difference found in regards to postoperative pain and other wound related complications.
Conclusions: We concluded that half vacuum suction drain ensures a lower drain collection and were removed earlier and hence reduced the hospital stay significantly than full vacuum suction drains.

Published: December 2023

Background: Aortoiliac disease management remains a subject of ongoing debate, with a shift in focus toward endovascular techniques, even in complex cases. This study aimed to evaluate and compare the safety and results of open surgery with endovascular surgery for treating TASC-II D aortoiliac lesions.
Methods: From January 2013 to February 2021, the clinical data of 89 patients revascularized with symptomatic TASC ΙΙ D AID were analyzed in a prospective cohort study. The patients were divided into two groups: open repair (61 patients) and endovascular treatment (28 patients). Baseline characteristics, preoperative and postoperative imaging, operation procedure reports and follow-up were reviewed and analyzed. Kaplan-Meier survival analysis, multivariate Cox regression, and a Propensity Score Matching (PSM) analysis were used to evaluate the relevance between risk factors and surgical technique.
Results: Open repair had a higher technical success rate (100% vs. 73.7%, p=0.01). 30-day major adverse cardiovascular (MACE) and limb (MALE) events showed no differences between both groups (PSM: 1 (4.8%) vs. 0, p=0.462 and 1 (4.8%) vs. 2 (13.3), p=0.235, respectively). Cox multivariable regression proportional hazard ratio showed no significant differences in terms of MALE between open and endovascular revascularization at 36 months (hazard ratio, HR 1.31 95% CI 0.56-3.06, p=0.54), even after PSM (HR 1.63 95% CI 0.58-4.55, p=0.35). Moreover, MACE and all-cause mortality also didn´t show a statistically significant difference between groups (HR 0.77 95% CI 0.22-2.64, p=0.67 and HR 0.97 95% CI 0.27-3.46, p=0.96).
Conclusions: Open and endovascular techniques are safe and effective treatments for complex AIOD. It is expected to have a higher technical success rate with open repair; however, there are no significant differences in MACE or MALE between these two approaches.

Authors: Uddin M. Borhan , Kamal S. M. Sorowar , Siddique Abu Bakar , Shams Fahmida
Published: December 2023

Background: Scrotal issues often prompt patients to seek evaluation through physical examinations and scrotal ultrasonography. Accurate diagnosis requires a comprehensive exploration of potential conditions, with both grayscale ultrasonography (USG) and duplex Color Doppler ultrasonography employed for assessment.
Methods: This prospective observational study, conducted at Dhaka Medical College Hospital in Bangladesh from July 2004 to June 2005, aimed to compare the effectiveness of grayscale ultrasonography and duplex color Doppler ultrasonography in evaluating scrotal pathology. Fifty-two patients with intra-scrotal disease were included using purposive sampling. Grayscale USG and duplex color Doppler ultrasonography were performed, and demographic and clinical data were processed using MS Excel and SPSS version 23.0.
Results: Grayscale ultrasonography identified hydrocele, varicocele, and epididymitis in 21%, 15%, and 13.5% of cases, respectively. Color Doppler imaging revealed various pathologies, with varicocele and hydrocele most common (21.20%). Diagnostic accuracy varied between the two techniques, with Color Doppler excelling in specific conditions such as testicular torsion (100% accuracy, sensitivity, and specificity). Overall, Color Doppler demonstrated superior accuracy (96.10%) compared to grayscale (80%).
Conclusions: While both grayscale ultrasonography and duplex Color Doppler ultrasonography are valuable tools for evaluating scrotal pathology, the latter demonstrates superiority in terms of accuracy, sensitivity, and specificity. Color Doppler's effectiveness in diagnosing specific conditions suggests its preference for comprehensive scrotal assessments.

This case report details the successful orthodontic camouflage treatment of a 21-year-old female with Angle's Class III malocclusion, characterized by skeletal and dental features. The patient opted against orthognathic surgery and, instead, underwent mandibular first premolar extraction for camouflage treatment. The case highlights the careful consideration of treatment options, including the decision to maintain a Class III molar relationship. The treatment achieved satisfactory results in skeletal, dental, and soft tissue aspects, demonstrating the viability of camouflage treatment for mild to moderate Class III malocclusions. The absence of established guidelines underscores the importance of personalized treatment planning for such cases.

Authors: Ivanov M. E. , Yezerskiy V. V.
Published: December 2023

The basic principle of parametric optimization according to the criterion of minimax of variance of the resulting error of estimation of the measured parameter is considered using the example of one of the main elements of an integrated measuring system – a ground speed meter. The meter consists of a Doppler ground speed sensor (location) and an accelerometer with a longitudinal axis of sensitivity (inertial). Based on the data on their measurement errors, the coefficients of the transfer functions of each channel of the meter containing these sensors were optimized. The result of the research is a comparative analysis of the resulting accuracy of the optimized meter for the invariant and non-invariant cases, based on the obtained graphs of the frequency distribution of variances. A reasonable conclusion is made about the advantage of an invariant or non-invariant meter depending on the frequency of the signal. The Matlab R2015a software was used for calculations.

Published: December 2023

The accuracy of a CFD model of a turbo-machine might depend on a number of factors: turbulence model, quality of the mesh model, boundary conditions, solver settings, consideration of secondary geometric factors, etc. The purpose of this work is to develop practical recommendations for CFD calculations of centrifugal compressors based on the validation of a model of NASA High Efficiency Centrifugal Compressor experimental radial compressor stage. Results of a grid independence test are presented, and the optimal grid size for the High Efficiency Centrifugal Compressor stage is identified as comprising 3 million elements. CFD-calculations of an experimental stage were performed with different turbulence models. The obtained data was compared with the NASA experimental data considering integral (total pressure ratio, mass flow rate, adiabatic efficiency) and differential parameters (static pressure distribution downstream the vaned diffuser). The required CFD computational time for different turbulence models was calculated. Based on the results of this research, recommendations were formulated for the application of SST, k–ε, BSL EARSM and GEKO turbulence models for numerical modeling of centrifugal compressors.
Fakt wiary czy wielki fakt wiary? Uwagi do książki Jacka Wojtysiaka Między ukryciem a jawnością
Authors: Dobrzeniecki Marek
Published: December 2023

John L. Schellenberg, autor argumentu z ukrytości, twierdzi, że gdyby Bóg istniał, to nie istnieliby rzetelnie niewierzący. W swej najnowszej książce Jacek Wojtysiak stwierdza, że teista może odwrócić to rozumowanie i stwierdzić, że gdyby Bóg nie istniał, to nie istnieliby rzetelnie wierzący. Dochodzi on nie tylko do wniosku, że wierzący istnieją, lecz jeszcze, że można przypuszczać, iż jest ich znacznie więcej niż niewierzących. Może zatem stwierdzić istnienie wielkiego faktu wiary, wobec którego ateista jest podwójnie bezradny: po pierwsze, nie umie go wyjaśnić, a po drugie – nie jest w stanie przedstawić paralelnego argumentu za ateizmem. W swoim artykule analizuję tę część książki J. Wojtysiaka, która jest poświęcona tym zagadnieniom i dochodzę do wniosku, że ateista jednak znajduje się lepszym położeniu, niż sugeruje to polski filozof.
Feminizacja, ale jaka? Rola kobiet w branży public relations w polsce na podstawie badań ilościowych
Authors: Szuba Przemysław , Tworzydło Dariusz , Gizicka Dorota
Published: December 2023

Artykuł – oprócz kwerendy literatury w kontekście aktualnej sytuacji kobiet na rynku pracy ze szczególnym uwzględnieniu branży PR – obejmuje zagadnienia badawcze dotyczące struktury płci w branży public relations w Polsce wraz z analizą czynników warunkujących sytuację wyjściową. Jednostką analizy są dane demograficzno-zawodowe 1789 specjalistów ds. PR, które zostały zagregowane i poddane analizie statystycznej. Dane pochodzą z kilku projektów badawczych realizowanych przez autorów w latach 2017-2023. Kobiety stanowią w nich blisko 2/3 badanych, czyli jest to dominująca płeć, jeśli chodzi o zatrudnienie w branży PR. Dlatego w ujęciu ogólnej struktury zatrudnienia mamy do czynienia ze zjawiskiem feminizacji branżowej. Jednakże wysoki poziom sfeminizowania nie przekłada się na strukturę zarządczą. W tym wymiarze kobiety odgrywają już znacznie mniejsza rolę niż mężczyźni (22% względem 33%). To z kolei rodzi pytania o obowiązujące zasady równości płci, różnorodności i integracji, a także jest przyczynkiem do analizy poziomu doświadczenia środowiska zawodowego PR. W artykule opracowany został model mediacyjny, za pomocą którego autorzy starali się wyjaśnić zależności pomiędzy zajmowanym stanowiskiem, doświadczeniem zawodowym i płcią.

A Study on Landscape Paintings of Geungjae (兢齋) Kim Deuk-shin (金得臣, 1754-1822)
Authors:   HUFS Institute of History and Culture, IM MI-HYUN
Published: December 2023

Geungjae (兢齋) Kim Deuk-shin (金得臣, 1754-1822) is known as one of the three genre painters along with Kim Hong-do (金弘道, 1745-1806?) and Shin Yun-bok (申潤福, 1758-1817 afterwards) or only as a painter who had been largely influenced by Kim Hong-do. In fact, he was a 44-year veteran Dohwaseo painter who had participated in important national art projects. Aside from his famous genre paintings, his extraordinary talent in portraits, landscapes, birds and animals, and flowers and animals established him as one of the best painters during the period. Especially, his results in Nokchwijae (祿取才: the state examination for court painters) demonstrates his ability in landscape painting among other themes as well as how much recognition he received at the time; some of these works are currently available.
Kim Deuk-shin’s landscape paintings carry two styles of landscape painting in Late Joseon Dynasty: literati landscape painting of the ideal and conceptual landscape and true-view landscape painting that painted mountains and rivers in Korea. This allows better understanding of his diverse works, as well as the variety of trends and transformations of the landscape painting in the Late Joseon Dynasty. In addition, compared to other themes such as genre, figure painting of Taoism and Buddhism, birds and animals, and flowers and animals that had been apparently influenced by Kim Hong-do’s style, his landscape painting has a different pattern due to being directly and indirectly influenced by a number of preceding painters including Jeong Seon (鄭敾, 1676-1759), Sim Sajeong (沈師正, 1707-1769), Kim Eung-hwan (金應煥, 1742?-1789), and Kim Hong-dothat were largely established in the area of landscape painting At the same time, it is also possible to observe the Gaeseong Kim family’s painting style from Kim Deuk-shin’s landscape paintings as they show association with those of his uncle Kim Eung-hwan, brother Kim Seok-shin (金碩臣, 1958-?) and Kim Ha-jong (金夏鍾, 1793-1875 afterwards). Kim Deuk-shin’s landscape painting style may have been passed on to Kim Seok-shinand Kim Ha-jong through secondary influence from Kim Eung-hwan, who was influenced by Jeong Seon and Sim Sajeong. Based on this, his landscape painting style appears to have had a significant influence on the establishment of the painting style within the Gaeseong Kim family and on later generations of court painters.
Aspects and Characteristics of Press Reports on the Korean War-era Massacres after April Revolution
Authors:   HUFS Institute of History and Culture, Lee Chang-hyun
Published: December 2023

This study shows how the press, after the April Revolution(1960), reported the massacres that had been occurred before/after the Korean War(1950-1953) and explains its characteristics. For these purposes, newspaper articles from the central/the local were analyzed as main materials and their perspectives were grasped from the editorials.
The press covered the stories of the massacres from recording the testimony of the bereaved(victims) and revealed more such cases in various places. From mid-May to early June 1960, these articles were plastered on the pages of major daily newspapers. Thus, massacres emerged as a political and social issue after the April Revolution. The press produced a variety of discourse analyzing them. On the premise of their illegality, the media made legitimate claims such as finding truth, punishing the perpetrators, and compensating the victims. The press also specifically explored these alternatives.
Baekje's attempt to restore Hanseong and Goguryeo's response: A theorem on the research trajectory of the Han River Basin territorial issues from 475 to 551
Authors:   HUFS Institute of History and Culture, Wee kaya
Published: December 2023

This article summarizes trends in existing research on territorial issues in the Han River basin from the fall of Hanseong in 475 to 551. While the research history summarized above has deepened our understanding of the territorial issues in the Han River Basin, the differences in their positions are still evident. In this article, I tried to recognize the problem clearly by organizing the research history of the Han River Basin territory issue from 475 to 551 in the chronological order in which the research was conducted. Based on the results, we suggest the possibility of exploring new perspectives to narrow the gap between the positions.
『Samguksagi』 ｢Baekjebongi｣ For the affirmative theory, the 'Baekje Continuous Perpetuation Theory', 'Baekje Temporary Loss Theory', and '529 Year Loss Theory' were presented, and for the negative theory, the 'Simple Negative Theory', 'Shift in the name of a region Theory', 'Manipulating history Theory', and 'Manipulating age Theory' were presented. As the discussion progressed, the possibility of a compromise interpretation of the written record and archaeological data was raised. This has opened up new interpretive possibilities for both the affirmative and negative positions. However, there is still a huge gap in our understanding of the written record and archaeological materials, and the discussion is at an impasse. The challenge for future research lies in the discovery of new perspectives that can break this impasse.
In this paper, we propose a complementary perspective to 'Shift in the name of a region Theory' from a positive perspective. A dynamic understanding of Baekje's occupation of the Han River basin since the early 6th century. The reason for this is understood from the point of view of ‘Gyochi(僑置)’.
Perovskite Solar Cell: Chemical Composition and Bandgap Energy via Machine Learning
Authors: Santos Filipi França dos , Da Silveira Kelly Cristine , Ferreira Gesiane Mendonça , Cariello Daniella Herdi , Andrade Mônica Calixto de
Published: December 2023

The exponential growth in publications and applications of perovskite photovoltaic cells highlights their significance in energy conversion and carbon emissions mitigation. From 2009 to 2023, the efficiency of these cells has significantly increased from 3.9% to 25.7%. The adaptive capacity of perovskite structures for solar spectrum absorption and current displacement is strongly influenced by the bandgap energy, ideally situated between 1.3 and 1.7 eV. Although various perovskite compositions can potentially attain this energy range, the synthesis methodologies remain empirically driven, presenting challenges to experimental viability. In this context, leveraging experimental databases provided by global researchers emerges as an effective approach to expedite and enable research on perovskite structures for photovoltaic cells. This study utilized the comprehensive MaterialsZone database to feed machine learning algorithms, focusing on Support Vector Machine (SVM) and Random Forest (RF) methodologies to predict the bandgap energy in a targeted perovskite composition. By conducting synthesis experiments towards specific compositions guided by model predictions, it becomes feasible to efficiently achieve the desired bandgap energy. Such a strategy not only accelerates research progress but also serves to curtail costs associated with the synthesis of perovskite materials. The RF model exhibited an average percentage error of 5.13%, a standard deviation of the percentage error of 6.99%, and a Root Mean Square Error (RMSE) of 0.119. In contrast, the SVM model recorded an average percentage error of 4.05%, a standard deviation of the percentage error of 6.45%, and RMSE of 0.881. These developed models not only demonstrate high predictive capacity but also contribute substantively to the comprehension of the intricate relationship between the chemical composition and bandgap energy values of perovskites. By deploying machine learning algorithms, this work paves the way for targeted optimizations and considerable strides in the manufacturing of perovskite-based photovoltaic cells.

This case study consists of an applied research that aims to identify weaknesses in the processing of neutral detergent responsible for variations in color, odor in a company specialized in sanitation and cleaning products located in Vale do Itajaí/SC. The monitoring of the production process was carried out for three months, evaluating: i) operational items: aptitude, method of execution, standard operating procedures (SOPs) and use of personal protective equipment (PPE); ii) raw material: formulation, quantities and inputs; iii) process water: magnesium, calcium and total hardness. Three preservatives from RDC nº30 and the mixture MIT/CMIT and Bromo-2 Nitro-2 Propanediol (Bronopol) CAS nº52-51-7 tested in this research were evaluated. The productive follow-up demonstrated that the operators were properly trained, carried out activities according to SOPs and used PPE. The preservative content in the formulation was adjusted to 0.28% of the mixture and there was a change in its operational sequence, inserting the thickener after adjusting the pH of the solution. The detergent obtained showed a slightly yellowish color, constant, uniform and without variation in odor after 14 days of elaboration. Physical parameters of the water showed calcium and magnesium hardness <15mg/L and total hardness 16.61mg/L, not interfering with the characteristics of the product or its performance. It is estimate that the problem with the neutral detergent was the preservative used and the operational sequence of preparation of the product, since positive results were obtained in the test formulation, without variation in color and odor after 14 days of preparation.

The global increase in the fleet of motorized vehicles, predominantly fueled by fossil fuels, poses critical environmental challenges. This study addresses the urgent need to mitigate adverse impacts such as air pollution and climate change through the development of electric motorcycles. Brazil and other regions face significant environmental challenges, with motorcycles being notable contributors to harmful emissions. Electric motorcycles emerge as promising alternatives, offering benefits such as zero emissions, cost reduction, and charging versatility. The continuous evolution of electric battery technologies plays a crucial role in the growing viability of electric motorcycles. However, aspects like range, maximum speed, and charging time require attention to ensure consumer acceptance and contribute effectively to emissions reduction and improved urban air quality. This article proposes a comprehensive analysis of the operational feasibility of converting combustion motorcycles to electric. Embedded in a project funded by FAPESC and led by the SENAI/SC University Center - Campus Joinville, the research addresses crucial aspects, including performance, range, and charging time. The selection and sizing of essential conversion components, such as the motor, battery, speed controller, and regenerative braking system, are meticulously discussed. The Motenergy ME1004 (ME1910), a brushed DC motor, was strategically chosen for its suitability for high currents and efficient speed control. This study was based on a specific methodology, allowing for precise calculations that determined the essential components for the realization of the research. The focus was on addressing the specifications of the motorcycle's kinematic set, providing a robust methodological approach for the development and characterization of these crucial elements.

The transportation sector is one of the largest emitters of greenhouse gases, contributing to climate change. Numerous initiatives have been adopted worldwide to reduce the emission of these gases, including the carbon credit market. The objective of this study was to review and contextualize mobility and pathways for transitioning to a low-carbon economy. The research was conducted using national and international databases and organizations related to the carbon credit market. Studies, reports, and documents were selected based on the following criteria: Materials related to mobility, sustainability, and carbon credit themes; in English, Portuguese, or French up until November 2022. The analysis of the information identified that life cycle analysis calculation methodologies are predominantly focused on nature, with little published about the transportation sector. Companies still need to incorporate environmental performance management through greenhouse gas emission inventories and evolve towards life cycle analysis of their products and services. In the global scenario, road vehicles account for 77% of the global carbon emissions from transportation (34% being heavy vehicles). Heavy vehicles disproportionately contribute more to the warming potential due to particle emissions. In conclusion, there is no single solution for the decarbonization of the transportation sector in Brazil; a combination of fleet renewal, biofuels, and improvements in the efficiency of the existing fleet, such as the electrification of the second axle of heavy vehicles, are essential to achieve Brazilian goals.

Aborda a formação de acervos decoloniais em bibliotecas públicas, comunitárias/populares e escolares como prática de mediação de informação, tendo em vista a importância de acervos que representem os aspectos culturais e identitários dapopulação brasileira. Tem como objetivo discutir a formação e o desenvolvimento de acervos, aproximando o pensamento da Biblioteconomia Social da perspectiva dos Estudos Decoloniais, e apresentando o contexto brasileiro acerca de acervos com temática afro-brasileira e africana em bibliotecas. Metodologicamente, trata-se de umarevisão de literatura com levantamento bibliográfico realizado na Brapci e no Google Acadêmico, em 2023, tendo recuperado 32 artigos e selecionado 16, que apresentam diagnósticos de acervos de bibliotecas na temática afro-brasileira e africana e/ou queversam sobre a formação e o desenvolvimento de coleções nessa temática. Como resultados, percebe que há poucos estudos que avaliam acervos de bibliotecas em relação a conteúdos e autores(as) afro-brasileiros e africanos, assim como trazindícios de ausência de conteúdos decoloniais nos acervos desse tipo de biblioteca; também apresenta aspectos referentes à elaboração de políticas de desenvolvimento de acervos decoloniais, em especial, em relação ao estudo de comunidade e àseleção de documentos. Por fim, considera que uma política de desenvolvimento de coleções é de extrema relevância para que se conheça a realidade local e se planeje um acervo que apoie a população, contribuindo para a libertação da dominação pelavia do saber.
Imágenes del delito

El presente artículo indaga la difusión mediática de las imágenes de los sistemas de videovigilancia. Se parte del supuesto de que las imágenes de las cámaras de seguridad se incorporaron a la industria de la noticia y el espectáculo como emergente de una tendencia a la espectacularización de la videovigilancia. En tal sentido, y a partir de lo que se define como una función expresiva de este tipo de dispositivos, los medios de comunicación son vistos como actores en las redes vinculadas a las políticas públicas de monitoreo urbano. Sobre la base de la realización de entrevistas en un municipio de la provincia de Buenos Aires, nos preguntamos por elpotencial simbólico de las cámaras de seguridad y el uso de las imágenes como forma de mostrar el “éxito” de las políticas de monitoreo público, y nos detenemos en una de las tendencias mediáticas de los últimos años: relatar noticias desde una estética de lo real que incorpora los registros audiovisuales de estos dispositivos. Como cierre, se recupera la percepción ciudadana sobre la difusión de las imágenes y se plantea un interrogante respecto de las redefiniciones de la efectividad y la eficacia de estos dispositivos a partir de los usos que surgen en la implementación de las políticas públicas.
De la Neutralidad de la Red al 5G
Authors: Gendler Martín
Published: December 2023

El artículo tiene como objetivo realizar una genealogía de dos de los principales procesos de discusión y ejercicios de saber-poder entre los actores constituyentes de Internet, quienes intentan modular su funcionamiento: nos referimos, por un lado, a la problemática de la Neutralidad de la Red y, por otro lado, al desarrollo del 5G. El foco del análisis se centra en las estrategias, alianzas, rivalidades y ejercicios estratégicos prácticos y discursivos desplegados por dichos actores (proveedores de servicios de Internet, proveedores de servicios y contenidos, organizaciones no gubernamentales, académicos y organismos del Estado), para configurar y modificar el escenario y las relaciones de poder entre ellos; es decir, para adecuar el ecosistema y la tecnicidad de Internet en función de sus propios intereses. El artículo presenta los antecedentes inmediatos de la problemática de la Neutralidad de la Red y analiza las discusiones que tuvieron lugar a lo largo de las primeras dos décadas del siglo XXI. Luego, el foco de atención se centra en los debates de instalación y despliegue del 5G, atendiendo principalmente al desarrollo del Network Slicing, que es capaz de generar fuertes cambios en el panorama existente y despertar nuevos cuestionamientos en el marco de las dinámicas de poder que atraviesan el ecosistema de Internet.

PROCES TRANZICIJE DETETA IZ PREDŠKOLSKE USTANOVE U ŠKOLU IZ UGLA RODITELJA
Authors: Krstić Kristina Dragan , Zuković Slađana
Published: December 2023

U radu se razmatraju promene s kojima se roditelji suočavaju kada prelaze u novu fazu roditeljstva, specifičnosti njihovog delovanja tokom detetove tranzicije iz predškolske ustanove u školu, a u vezi sa tim i značaj tranzicione prakse za uključivanje roditelja u taj proces. Shodno tome, u radu su prikazani rezultati ispitivanja mišljenja roditelja o preprekama za njihovo intenzivnije uključivanje, kao i njihovi predlozi o načinima prevazilaženja tih prepreka i mogućnostima unapređenja detetove pripreme za polazak u školu. Uzorak su činili roditelji dece pripremnog predškolskog programa iz sledećih opština: Šabac, Valjevo, Loznica i Beograd. Nalazi do kojih se došlo ovim istraživanjem pokazuju da su roditelji kao prepreke intenzivnijem uključivanju u aktivnosti predškolske ustanove/škole identifikovali socioekonomske i zdravstvene poteškoće, radno vreme i prirodu posla, teorganizacione poteškoće unutar porodice. Kao pitanja kojima je potrebno posvetiti posebnu pažnju kako bi se olakšao detetov prelazak iz predškolske ustanove u školu roditelji su izdvojili domen detetove spremnosti za školu, uspostavljanje kontinuiteta u uticajima razvojnih okruženja, kao i klimu obrazovne ustanove. Predlozi koje su roditelji dali pružaju uvid u potrebe roditelja i dece tokom ovog tranzicionog perioda. Dobijeni rezultati mogu predstavljati polazište za koncipiranje tzv. tranzicionih programa koji u većoj meri uvažavaju mogućnosti i potrebe roditelja tokom detetove tranzicije iz predškolske ustanove u školu.
