Authors: Gangga Bramantya Pradana  , Nalim Nalim
Published: December 2024

Students often face difficulties in understanding geometric concepts, particularly in the Pythagorean theorem as well as in plane and solid geometry, necessitating innovation in teaching methods. This study aims to examine the effect of problem-based mathematics learning using the Creative Visualization technique on improving the geometry skills of eighth-grade students at SMP Islam Wonopringgo, based on Van Hiele’s theory. The study employed a quasi-experimental method with a pretest-posttest control group design. The sample consisted of two purposively selected classes: the experimental class, which received instruction using the Creative Visualization technique, and the control class, which followed conventional teaching. The research instrument was a geometry skills test based on Van Hiele's five levels of geometric thinking. The results showed a significant difference in the improvement of geometry skills between the two groups. Students in the experimental class showed more significant progress, particularly at the analysis and informal deduction levels. Thus, the Creative Visualization technique is proven to be effective in enhancing students’ geometry skills and can be considered an alternative method in geometry instruction.

Authors: Muhammad Waqas
Published: December 2024

The study aimed to evaluate the effects of postural correction exercises and pelvic tilt exercises on pain intensity, range of motion (ROM), and functional abilities in pregnant women with lower back pain. A quasi-experimental study was conducted at Family Welfare Hospital and Ali Clinic Lahore, Pakistan. A total of 24 pregnant women with lower back pain, meeting the inclusion and exclusion criteria, were allocated into two equal groups. Group 1 (Postural Correction Exercises) and Group 2 (Pelvic Tilt Exercises). Each group consisted of 12 participants. Both groups underwent a comprehensive pre-intervention assessment to establish baseline measurements using the Visual Analog Scale (VAS) for pain, goniometry for ROM, and the Oswestry Disability Index (ODI) for functional abilities. The data was normally distributed between groups, necessitating the use of the One-way ANOVA test, which revealed significant improvements in both groups (p < 0.001). One-way ANOVA showed significant decreases in VAS and ODI scores and significant increases in trunk flexion and extension ROM in both groups (p = 0.001). The effect size for changes in pain was moderate (Cohen d = 0.78), and for functional disability, it was large (Cohen d = 0.85), favoring Group 2. Both postural correction and pelvic tilt exercises are effective for managing lower back pain in pregnant women, improving pain levels, ROM, and functional abilities. Pelvic tilt exercises demonstrated a more pronounced impact on functional disability improvements. These findings support the inclusion of these exercise regimens in prenatal care.

Authors: Wang Lei
Published: December 2024

Objective: Bone marrow mesenchymal stem cells (BMSCs) play a vital role in cell therapies and regenerative medicine, but their fate in the host remains unknown and the standard of culture is waiting to be established. Green fluorescent protein (GFP) transgenic mice provide a potent tool to investigate its fate in vivo. However, the culture method on the BMSCs in GFP mice remains to be explored. Methods: The femur and tibia from healthy 6~8-week-old GFP transgenic mice were used to isolate BMSCs which were cultured and observed under inverted microscopy and fluorescence microscopy. Results: BMSCs were successfully collected and cultured from the femur and tibia. The cells were observed to be round in shape, homogeneous, and transparent within 2-10 h in primary culture inoculation. The cell growth of the walled cells varied in different periods with different shapes like round, spindle and pterygoid in the first week, and uniformed in 3rd passage with a pterygoid shape. CD44 staining confirmed BMSCs characteristics. Conclusions: BMSCs from GFP-transgenic mice have been successfully cultured and identified, which makes them an ideal cell source for later usage, including the recognition of migration and differentiation of BMSCs in vivo.

FEMINICÍDIOS E DESAPARECIMENTO DE PESSOAS
Authors: Oliveira Edinaldo Rodrigues de
Published: December 2024

A dinâmica legislativa atualmente presente na América Latina, que vem ampliando o conteúdo de normas objetiva e incorporando na sequência maior diversidade de formas reconhecidas de violências sexistas, responde num primeiro momento à necessidade de visibilizar e punir os perpetradores.
Contudo, mais do que uma (re)ação, o Estado deve se preocupar também em desenvolver as ferramentas que permitam diagnosticar com a maior precisão possível o evento, chancelando, neste terreno, a possibilidade de as violências contra o sexo feminino ser muito mais amplo do que os conceitos atualmente adotados. 
Feminicídios, homicídios contra mulheres e desaparecimentos de mulheres e meninas estão umbilicalmente ligados e se constituem em um complexo fenômeno social que não pode ser tratado de modo separado.
O marco legislativo regulatório deve vir acompanhado de outras etapas, devidamente respaldado em evidências, que incorporem além das atividades de persecução penal, serviços essenciais de qualidade e prevenção daquela que pode ser considerada uma das epidemias mais danosas que se tem conhecimento. 
Dito de outra forma, a violência de gênero, além de letal, persiste de maneira cruel e silenciosa na América Latina o que exige o empenho de todos – governos e sociedade – para frear o seu avanço destrutivo.

Methods: A total of 50 patients with breast cancer confirmed by surgical pathology were randomly selected and underwent high-frequency breast ultrasound examination, focusing on observing the shape, edge, posterior echo, microcalcification, internal blood flow, and axillary lymph nodes of the mass; immunohistochemistry was used to detect the expression of ER, PR, and CerbB-2 genes, and their relationship with ultrasound performance was analyzed. Results: ① The detection rate of microcalcification in breast cancer <2cm was the highest, followed by spiculated edge; the detection rate of irregular shape was higher in tumors >2cm. ② The positive rate of ER and PR in patients with a tumor aspect ratio >1 was 77.8% and 61.1%, respectively, which was higher than those with an aspect ratio ≤1 (P<0.05); ③ The positive rate of ER and PR in patients with spiculated edge signs was 65.5% and 55.2%, respectively, which was higher than those without spiculated edge (P<0.05); ④ The positive rate of ER and PR in patients with peripheral high echo dizzy was 73.3% and 60.0%, respectively, both higher than those without high echo dizzy (P<0.05); ⑤ The positive rate of PR in patients with anechoic area was 22.2%, lower than those without anechoic area (P<0.05); ⑥ The positive rate of CerbB-2 in patients with microcalcification was 83.3%, higher than those without microcalcification (P<0.05). Conclusion: There is a certain relationship between the ultrasound performance of breast cancer and the expression of molecular biological indicators, and the biological characteristics of the tumor affect the ultrasound performance of breast cancer. Ultrasound examination can provide imaging basis for the prognosis assessment and clinical treatment selection of breast cancer.
Exploring the Adoption of E-Commerce among Small and Medium Enterprises in Saudi Arabia: A Technology-Organization-Environment Perspective
Authors: Hamida Abdel Ghaffar
Published: December 2024

This study investigates the factors influencing e-commerce adoption among Saudi Arabian Small and Medium Enterprises (SMEs) using the Technology-Organization-Environment (TOE) framework. The research aims to identify key determinants that either facilitate or hinder e-commerce adoption in the Saudi context. A web-based survey was conducted among 480 Saudi Arabian SMEs (32% owners, 68% managers), employing multiple regression analysis to test eight hypotheses derived from the TOE framework. Variables were measured using established scales with Cronbach's alpha exceeding 0.80, examining eight independent variables across technological, organizational, and environmental contexts. Results revealed technology infrastructure as the strongest predictor (β = .576, p < .001), followed by IT human resources (β = .341, p < .001), business infrastructure (β = .156, p = .008), business partner pressure (β = .123, p = .039), and technical infrastructure (β = .075, p = .015). Notably, competitive pressure, government support, and firm size did not show significant influence on e-commerce adoption. The model explained 33.3% of the variance in e-commerce adoption. Study limitations include its cross-sectional design, sample size representing less than 10% of total Saudi SME population, and potential limited generalizability beyond the Saudi Arabian context. Future research should consider longitudinal studies and cross-country comparisons. The findings suggest organizations should prioritize investment in technology infrastructure and IT human resources, while policy makers need to reassess current support mechanisms for SME digital transformation. Technology providers should focus on integrated solutions addressing both technical and business infrastructure needs. These results can inform strategies to achieve Saudi Vision 2030 digital transformation goals. This study provides the first comprehensive analysis of e-commerce adoption factors among Saudi SMEs using the TOE framework, challenging traditional assumptions about technology adoption drivers and offering evidence-based insights for stakeholders involved in Saudi Arabia's digital transformation.
UKPDS 44 Years of Follow Up Legacy
Authors: Jain Rajesh

The UKPDS 33-year study showed that an intensive glucose arm significantly reduces microvascular complications over a 10-year duration in patients with less than 6 years of newly diagnosed (T2DM) diabetes [1]. Overall, there was a good reduction in macrovascular complications in this duration, but it did not reach a statistical level. The patients were followed up for 10 years, and later, in 1997, the study was published. The microvascular benefits were still statistically significant after another 10 years despite the intensive group’s glycaemic control deteriorating in the later years to approach the control group’s glycaemic control. This is often labelled as the “legacy effect”. Further, after the subsequent 10 years, macrovascular benefits became statistically significant. It’s been 44 years since the participants started the study in 1977. A preliminary report on the 44-year outcomes was presented recently at the EASD 2022 in Stockholm.

Fruto del debate e intercambio de ideas durante el curso de verano «La situación de la víctima de trata en tiempos de COVID 19», celebrado en la sede de la Universidad Pablo de Olavide en Carmona, nace esta obra colectiva, dirigida a estudiantes y profesionales de la Fiscalía, Judicatura, Abogacía, Fuerzas y Cuerpos de Seguridad del Estado, así como a estudiantes y profesionales de la sanidad, medicina legal, psicología, trabajo social, educación social y criminología.

La trata es un atentado a los derechos humanos y un problema global, por lo tanto, debemos dar una respuesta integral e intersectorial, con un objetivo común, la protección integral a las víctimas. Desde el ámbito internacional partimos del Protocolo para prevenir, reprimir y sancionar la trata de personas, especialmente mujeres y niños (Protocolo de Palermo), donde se insta a los Estados parte a adoptar «medidas legislativas y de otra índole que sean necesarias para tipificar este delito en su derecho interno».

El objetivo de esta obra es abordar, desde una perspectiva multidisciplinar, la situación que sufren las víctimas de trata, especialmente las más vulnerables; mujeres, personas con discapacidad, niños y niñas, cuya captación, explotación y trato como mercancía se lleva a efecto por organizaciones criminales.

Para ello contamos con la aportación de profesionales del ámbito académico, abogacía, atención psiquiátrica a las víctimas y asociaciones, con el objetivo común de reflexionar para una mejora de la prevención y protección de las víctimas de trata y aportar propuestas de lege ferenda y de política criminal acordes con un tratamiento multidisciplinar, así como analizar la divulgación que desde el cine, tanto de ficción como documental, se realiza para trasladar la realidad de la trata a la sociedad.
LA PROTECCIÓN INTERNACIONAL DE LAS VÍCTIMAS DE TRATA DE SERES HUMANOS

En el presente capítulo analizaremos partiendo de la definición internacional de trata de seres humanos establecida en el Protocolo de Palermo, los mecanismos para combatir y prevenir la trata de seres humanos en un mundo globalizado en el que la crisis alimentaria, energética, climática y financiera, incrementada por la pandemia y la guerra en Ucrania, dibujan un escenario en el que se hace más necesario que la Comunidad Internacional de forma solidaria refuerce los canales de cooperación a nivel judicial, penal, financiero y policial y establezca políticas de cooperación al desarrollo para prevenir la trata de personas, reducir el sufrimiento y la explotación de las víctimas: hombres, mujeres y menores, que incrementan su vulnerabilidad por su condición de migrantes, refugiados, o víctimas de un conflicto armado.
