Acerca de la prueba, en el código orgánico general de procesos (COGEP)
Authors: Guerrero Machado Marco
Published: January 2025

A través de la presente investigación, luego de realizar un análisis –principalmente- acerca de cómo está regulada la incorporación de la prueba en el proceso civil, lo que se ha hecho es (partiendo de observancias puntuales a los requisitos de formalidad dispuestos por el legislador para este cometido), elaborar una propuesta para el mejoramiento de esa fase de dicha institución procesal. De esta manera, no es un aporte la existencia de las formalidades para la materialización de la prueba. Esto necesariamente tendría que traer como resultante una reforma al Código Orgánico General de Procesos. Nuestro sostenimiento es que solo aquellas reformas harían que un proceso civil en esta fase cobre una mejoría necesaria, todo ello al amparo de los propios designios constitucionales.
The Cause of King Saul's Failure from the Perspective of Transformational Leadership
Authors:   Inst Futur Soc Christ, You Kyoung-Ho , Leem Tae-Jong
Published: January 2025

The purpose of this study is to analyze the cause of King Saul's failure from the perspective of transformational leadership. Prior research mainly summarized their leadership characteristics by finding examples of successful leaders among biblical figures. However, it is necessary to analyze failed leadership in that there are many failed leaders among biblical figures and various perspectives are needed in leadership analysis. For this study, we look at the Bible content, the study that analyzed King Saul from a theology perspective, and the study that deals with transformational leadership from a business administration perspective. Transformational leadership was first conceptualized by Burns (1978) and its constituent factors are charisma, individual consideration, intellectual stimulation, and inspirational motivation (Bass and Avolio, 1994). Saul is splendidly crowned as the first king of Israel by God's choice, but fails to demonstrate leadership and falls. From the perspective of transformational leadership, King Saul has the following problems. (1) Saul lacked charisma, such as making his subordinates tremble and not being able to role models on his own (1 Sam 13:6-9). (2) Saul lacked individualized consideration, such as not allowing the soldiers to eat food in the war against the Philistines (1 Sam 14:24). (3) Saul was unable to intellectually stimulate his subordinates to solve problems when Goliath insulted God (1 Sam 17:1-16). (4) Saul was insufficient to be an inspirational motivation through a sharing vision(1 Sam 17:1-16).
The Aesthetic Characteristics of the Ancient Chinese Poetry Art Song, Song of Autumn (秋之歌)
Authors:   Inst Futur Soc Christ, Zhou Xuan , Eum Yeong-Cheol
Published: January 2025

This study analyzes the aesthetic characteristics of Song of Autumn, an art song based on ancient Chinese poetry and lyrics, created by the famous Chinese composer Luo Zhongrong in the early 1960s. The work is based on the “Three Poems” by the Tang Dynasty poet Du Mu and includes three pieces: Mountain Walk(山行), On the Road to Nanling (南陵道中), and Sending Off Judge Han to Yangzhou (寄揚州韓綽判官). The summary of the analysis of the aesthetic characteristics of Song of Autumn is as follows:First, in terms of artistic imagery and sentiment, all three pieces beautifully depict the scenery of late autumn through varying forms of accompaniment and melodic lines. Second, the aesthetic value embedded in the lyrics is revealed through the portrayal of forest landscapes, a woman with red sleeves, and reflections on the 24-bridge scene. Third, the expressive techniques accompanying the singing are manifested through the use of rich piano harmonies, double-note melodies in triplets, and ornamented notes, reflecting the characteristics of Chinese poetic language.
Additionally, the three pieces in Song of Autumn also demonstrate aesthetic qualities in terms of rhythm, pronunciation, vocal technique, training methods, and stage effects. Thus, Song of Autumn can be considered an art song that beautifully embodies literary, musical, and sentimental beauty.

Authors: Fonseca Victor Marcos dos Santos Catete , Oliveira Sandro Ronaldo Bezerra
Published: January 2025

Este artigo explora o desenvolvimento de um processo de aprendizagem para a produção de animação stop-motion. A pesquisa surge a partir da necessidade de engajar estudantes de ensino superior dos cursos de produção multimídia e cinema em novas abordagens que integrem o uso do miriti a técnicas de animação. O problema central investigado é: como os estudantes podem aprender a produzir animações stop-motion usando miriti? À vista disso, desenvolveu-se um protótipo de processo de aprendizagem que iniciou-se a partir de uma revisão quasi-sistemática de literatura (RQSL), seguida da criação de um protótipo e avaliação de um especialista. A RQSL selecionou 5 estudos que abordam o ensino-aprendizagem de animação stop-motion no ensino superior e pesquisas sobre o uso do miriti em animações. Verificou-se o uso de abordagens ativas para ensino de animação e que essas auxiliam os estudantes no desenvolvimento de diversas habilidades. Além disso, elas promovem uma aprendizagem engajada e significativa. Também constatou-se o uso de miriti em produções audiovisuais animadas e a existência de formações que o utilizam como recurso. Os achados observados nesses estudos fundamentaram a elaboração de um protótipo teórico baseado na metodologia ativa de design thinking (DT). Esse protótipo foi submetido à análise crítica de um especialista, cujas alterações sugeridas auxiliaram na modelagem final da proposta. Assim, além de identificar achados valiosos e contribuir para pesquisas acadêmicas futuras, o presente trabalho fomenta novos caminhos para a aprendizagem no campo do audiovisual.
Assessing Teachers’ Dispositions Towards Culturally Responsive Pedagogy in Northwest Arkansas High Schools
Authors:   University of Arkansas, Fayetteville, Ford Rylie
Published: January 2025

Culturally responsive pedagogy (CRP) entails the use of cultural knowledge, prior experiences, and learning styles of ethnically and culturally diverse students to make instruction more relevant and effective for them. Furthermore, practices within this pedagogy are validating, inclusive, emancipatory, and ethical, and help diverse students succeed academically while maintaining their cultural identity. Numerous studies have indicated that using culturally responsive pedagogy increases student academic achievement, sense of self, and emotional well-being (Ladson-Billings, 1995a; Gay, 2018). Considering the varying degrees of cultural and linguistic diversity in Northwest Arkansas (NWA) schools and the lack of reported professional development relating to CRP, this study aimed to examine NWA secondary teachers’ dispositions (values, attitudes, and beliefs) toward culturally responsive pedagogical practices. Employing a mixed methods survey research design, the study integrated self-reported Likert scale ratings and open-ended questions for a more in-depth understanding of teachers' challenges while incorporating CRP into their classrooms. This study presents the online survey results of 131 teachers from 9-12 grades from various regional districts. Findings indicate that NWA secondary teachers report having positive perceptions toward culturally responsive pedagogical practices. Further analysis also suggests factors, such as subject area taught and years of teaching experience, that may impact teacher dispositions. These findings are significant because they indicate potential areas of concern regarding equitable teaching relevant to teacher preparation, training, and support for CRP. They can be used to develop more meaningful, tangible, and supportive professional development. These results could also impact the decisions made by school administrators regarding matters related to CRP, affecting both teachers and the overall school culture.

Authors: Kono Kenichi , Taketomi Shuji , Yamazaki Takaharu , Kage Tomofumi , Tamaki Masashi , Inui Hiroshi , Tanaka Sakae , Tomita Tetsuya
Published: January 2025

Background:

The effect of axial rotation between the femoral neck and ankle joint (total rotation [TR]) on normal knees is unknown. Therefore, this study aimed to investigate the TR effect on normal knee kinematics.

Methods:

Volunteers were divided into groups large (L), intermediate (I), and small (S), using hierarchical cluster analysis based on TR in the standing position. TR was measured using three-dimensional (3D) bone models generated from CT. A two-dimensional to 3-dimensional registration technique was used to assess the spatial position and femur and tibia orientation during squat. The axial rotation, varus-valgus alignment, and anterior-posterior translation of the femur relative to the tibia were evaluated.

Results:

Group L had the highest TR, whereas group S had the lowest TR (L: 36.6° ± 6.0°, I: 23.2° ± 3.0°, and S: 13.8° ± 5.1°). Above 50° of flexion, femoral external rotation was greater in group S than in groups L and I. From 40° to 110°, the medial side was more anterior in group L than in groups I and S, whereas the lateral side was more posterior in group S than in groups L and I.

Conclusions:

Individuals with larger TR had more femur anterior-medial translation relative to the tibia.

Recently the concept of fuzzy set theory is used to introduce the
notion of fuzzy differentiation by several authors in the field of geometric function theory. In this paper, fuzzy differential subordination and fractional differential operator are employed to define certain new classes of analytic functions
in the unit disc. Several new interesting results, such as some inclusion relations, convolution and integral preserving properties, for these classes are
discussed. Some significant special cases of our main results are also pointed
out.
q-DEFORMED AND λ-PARAMETRIZED A-GENERALIZED LOGISTIC FUNCTION BASED COMPLEX VALUED TRIGONOMETRIC AND HYPERBOLIC NEURAL NETWORK HIGH ORDER APPROXIMATIONS

Published: January 2025

Here we research the univariate quantitative approximation of
complex valued continuous functions on a compact interval by complex valued neural network operators. These approximations are derived by establishing Jackson type inequalities involving the modulus of continuity of the
engaged function’s high order derivatives. The nature of our approximations
are trigonometric and hyperbolic. Our operators are defined by using a density
function generated by a q-deformed and λ-parametrized A-generalized logistic
function, which is a sigmoid function. The approximations are pointwise and
of the uniform norm. The related complex valued feed-forward neural networks
are with one hidden layer.
“ESS LIM INF” PROPERTY OF PLURISUPERHARMONIC FUNCTIONS
Authors:   Department of Mathematics and Statistics, P.O. Box 68 (Pietari Kalmin katu 5), FI00014 University of Helsinki, Finland, Koskenoja Mika
Published: January 2025

We present an analytic approach to plurisuperharmonic functions
based on the Levi form in the sense of distributions in Cn. We observe that
the Sobolev space W1,2
loc is a favourable function space to consider plurisuperharmonic functions. Using the distributional approach we derive several
properties of plurisuperharmonic functions, mostly well-known in pluripotential theory but deduced applying different methods. In particular, we show
that plurisuperharmonic functions satisfy so called “ess lim inf” property.
KANNAN TYPE ASYMPTOTIC CONTRACTIONS IN THE SENSE OF KIRK

Inspired by Kirk’s pioneering work, we initiate the concept of Kannan type asymptotic contractions. Using two constructive lemmas, we establish a fixed point theorem for Kannan type asymptotic contractions. What’s
more, we present a fixed point result for asymptotic contractions concerning
the generalization of weakly Ciri´c type. This theorem generalizes and im- ´
proves the results for Kirk’s asymptotic contraction introduced by Suzuki and
for Kannan type asymptotic contraction.

In this paper, we study the first and second fundamental forms of
surfaces, exploring their properties as they relate to measuring arc lengths and
areas, and identifying isometric surfaces. These forms can be used to define the
Gaussian curvature, which is, unlike the first and second fundamental forms,
independent of the parametrization of the surfaces. Also, we investigate the
geometric behaviour of rectifying curves on regular surfaces under conformal
and isometric transformation by using the concept of fundamental forms of
surfaces.

The study explores the impact of parental involvement and teachers’ strategies on the development of social skills among diverse learners in the Schools Division of Iloilo City for the school year 2023-2024. Utilizing a survey and correlational research design, data were collected from 138 kindergarten teachers across ten districts. Statistical tools such as descriptive statistics were used to analyze the levels of parental involvement and teachers’ strategies, while Pearson correlation was employed to examine relationships between these variables and the development of social skills. The findings revealed that while certain social skills, such as giving compliments and effective time management, are emphasized in classrooms, others, like volunteering and conflict management, require further development. Teachers’ strategies and parental involvement were found to influence the development of these skills, although no significant correlations were identified between them. The study underscores the importance of a collaborative approach involving parents, teachers, and other stakeholders in fostering social skills among diverse learners, suggesting that a holistic and inclusive approach is necessary for effective social development.

This study aims to evaluate the managerial competence, decision-making skills, and learning environment among elementary schools in the Schools Division of Antique, Philippines, during the school year 2023-2024. A descriptive-correlational research design was employed, utilizing a structured questionnaire administered to 365 randomly selected teachers. Statistical tools such as descriptive statistics were used to summarize the levels of managerial competence, decision-making skills, and learning environment. Chi-square tests identified significant variations in competence and skills based on factors such as civil status, educational attainment, school size, type, and length of service. Pearson correlation analysis was applied to determine the relationships between managerial competence, decision-making skills, and the learning environment. The study reveals that while school heads generally exhibit very high levels of managerial competence and decision-making skills, these significantly influence the quality of the learning environment. The study concludes that enhancing managerial competence through targeted professional development and collaborative practices is crucial for fostering a conducive learning environment in schools.

This study examines the collaborative practices, innovativeness, and creativity of secondary teachers in the Schools Division of Iloilo, Philippines, during the 2023-2024 academic year, in the context of the Fourth Industrial Revolution’s demands for innovative approaches to teaching and learning. Grounded in Collaborative Learning Theory (Dillenbourg, 2010) and Social Constructivism (Vygotsky, 2010), the study explores how teachers’ profiles—such as educational attainment, length of service, position, school type, and congressional district—influence their collaboration, innovation, and creativity in educational settings. Utilizing a quantitative descriptive-correlational design, data were collected from 283 junior high school teachers through a validated questionnaire. Statistical tools such as chi-square tests were used to determine significant differences among demographic groups, while Pearson correlation was employed to assess relationships between collaborative practices, innovativeness, and creativity. Results indicate that teachers exhibit consistent collaborative practices regardless of their demographic or contextual factors, while significant differences in innovativeness are observed based on educational attainment (p < 0.05). However, creativity levels remain uniform across different classifications (p > 0.05). The findings reveal no significant relationships between collaborative practices and either innovativeness or creativity (p > 0.05). The study concludes that while secondary teachers in Iloilo demonstrate a willingness to collaborate and innovate, targeted professional development is necessary to enhance innovativeness and foster creativity effectively. Recommendations include developing professional development programs, promoting open feedback and collaboration, and providing equitable access to technological resources.
