Bamboozled! High-aspect-ratio TiO2 nanowires (see image) that are vertically split off from anodic titanium oxide nanotubes prepared by anodization of foils. The bamboo-splitting model based on the hydrolysis a small amount water in viscous ethylene glycol at high voltage is proposed as mechanism formation nanowires.

The purpose of this study was to explore the lived experience women in leadership Korea and identify challenges opportunities that they face process balancing work family life developing as uniquely challenging Korean workplace where organizational cultural constraints. Critical investigation understanding concepts frequently represented previous literature about leadership: work–family balance, women's development, context. In-depth interviews were conducted with 18 leaders selected through...

In this qualitative study, we explored the experiences of 26 engineering student mentors and mentees in a peer mentoring program. We found that exploited program's fluid structure situated social relationships to enact specific type academic/professional goal identity conducive their entry one two communities practice, on-campus program community professional engineers. The functioned as space which identities these students converged diverged, creating subtle tension self-reflection...

This study is a descriptive content analysis of "smart learning" as defined and conceptualized by Korean educational researchers from 2010 to 2018. The purpose research examine the smart learning literature for core conceptual elements that ran through scholarly discourse in South Korea; understand how three environment, pedagogy, learner, are represented those definitions elucidate some notable trends its development throughout years. We utilized Google Scholar, Citation Index, RISS collect...

Objective . To evaluate the utility of gray scale harmonic ultrasonography with a microbubble contrast agent in early assessment therapeutic response to radio frequency ablation for hepatocellular carcinoma. Methods Seventy‐five patients 81 nodular carcinomas (1.3–4.8 cm) treated percutaneous were evaluated contrast‐enhanced after intravenous bolus injection galactose‐based agent. The vascularity within zones was continuous scan 3 5 seconds between 15 and 30 initiation injection. perfusion...

To assess the potential of contrast-enhanced gray scale harmonic sonography in evaluation typical vascular and enhancement patterns hepatic focal nodular hyperplasia.Thirteen patients with 13 lesions hyperplasia underwent sonography. After injection a microbubble contrast agent (SH U 508A), sonographic studies using Coded Harmonic Angio technique were performed combination period continuous scanning to pattern (vascular imaging) interval delay determine sequential (acoustic emission...

In this paper, a method to prepare anodic porous niobium oxide with thickness of more than half micrometre is described in terms delaying the chemical dissolution formed fluorinated electrolytes either by controlling anodization temperature or making protective oxide. It was revealed that both growth rate and formation films increase as increases. X-ray diffraction (XRD) x-ray photoelectron spectroscopy (XPS) analyses show anodically prepared consists amorphous Nb2O5.

In this interpretative phenomenological study, the implicit cultural values and expectations embedded in faculty/staff's perceptions how they functioned as a hidden curriculum against student veterans' smooth transition into higher education were analyzed based on in-depth interviews with 20 veterans 9 faculty/staff members. By clarifying points of misunderstanding/misjudgment consequences experienced by veterans, we offer culturally sensitive perspective challenges during transition....

School discipline disparities for African American students in urban schools continue to be a topic of contention. While research has rightfully called into question the practices and preparation teachers principals, role that assistant principals serve as disciplinary gatekeepers gone relatively unnoticed literature. The purpose this study was explore experiences five at two middle ascertain how they addressed issues race amid applying school interventions students. findings are analyzed...

This article describes the process and findings of a community study that was part task force to improve educational experiences for new English learners, particularly large number Latinos. Based on analysis series focus group interviews survey, discusses how students coming from other countries are usually accustomed different classroom environment may be confused about relate with their teachers during class. At same time, educators not possess adequate knowledge students’prior cultural...

This study examined whether or not embodied-agent-based learning would help middle-grade females have more positive mathematics experiences.The used an explanatory mixed-methods research design.First, a classroom-based experiment was conducted with one hundred and twenty 9 th -graders introductory algebra (53% male 47% female; 51% Caucasian 49% Latino).The results revealed that learner gender significant factor in the learners' evaluations of their agent (η 2 = .07),the task-specific...

This article is a cross‐case study exploring two young African‐American adolescent girls' experiences with school mathematics and the impact of socio‐cultural context upon their motivation mathematical identity. Based on repeated in‐depth interviews ethnographic observation classroom, researcher portrays contrasting pictures sixth‐grade girls who are ironically faced same end‐of‐the‐year‐results despite differing personal academic profiles. Overall data analysis reveals profound ethnicity...

In the present study, school belongingness was explored in context of a mathematics classroom over course one academic year. In-depth interviews with eight African American middle students and their three White teachers were conducted at two time periods. This phenomenological qualitative investigation girls revealed primary themes personal connection authentic pedagogy. As practitioners researchers continue to examine factors related student achievement, empirical research should highlight...

This study explored the impact of race on higher education transition experiences three groups male student veterans: Black, Hispanic/Latinx, and Asian. Grounded in premise Critical Race Theory, especially Cabrera's Hegemonic Whiteness Yosso's Cultural Capital, we collected analyzed 17 veterans' in-depth interviews centering voices participants marginalized due to race, age, veteran status. Findings confirm that veterans color face acute cultural alienation racism college campuses enact...

This study explores how recent Korean immigrant students experience learning social studies and their unique social, cultural, educational backgrounds as new immigrants shape experiences in American schools. Based on survey in-depth interviews with 43 two urban three suburban/rural areas, this mixed methods examines youths’ perceptions about the nature of history well everyday classroom contexts. Our data analysis demonstrates that face varying difficulties constructing meaning US engaging...

This article reports a cross-case analysis examining the impact of class and race upon two young adolescent girls' experiences with school mathematics. Based on repeated in-depth interviews ethnographic observation their mathematics classroom, researcher portrays contrasting pictures high-achieving, young, girls who come from different racial backgrounds. Although very small sample, this study reveals intertwined as well teacher's evaluation academic potential in discipline. I argue that...

Abstract This paper explores how undergraduate students understood the social relevance of their engineering course content knowledge and drew (or failed to draw) broader ethical implications from that knowledge. Based on a three-year qualitative study in junior-level class, we found had difficulty acknowledging aspects as relevant topics coursework. Many considered immediate technical usability or improved efficiency innovations noteworthy engineering. Findings suggest highly-structured...

To determine the findings of various focal hepatic lesions at contrast-enhanced gray-scale ultrasound (US) using a coded harmonic angio (CHA) technique and emphasizing lesion characterization.The study involved 95 patients with 105 lesions, namely 51 hepatocellular carcinomas (HCCs), 22 metastases, hemangiomas, four cases nodular hyperplasia (FNH), six nontumorous nodules. After injection microbubble contrast agent (SH U 508A), US studies CHA were performed combination continuous scanning to...
