Competencies of school health staff (SHS) members, including school nurses, are crucial to improving child and adolescent health. In Vietnam, although SHS members are dispatched to schools, they have limited training opportunities. This study identified SHS members’ training needs in a province of Vietnam. A cross-sectional, online survey was conducted with 204 SHS members. The performance and importance of SHS members’ competencies were measured using 59-items and rated by a 5-point Likert scal

Abstract Multicultural adolescents (MA) in Korea experience higher depression and lower life satisfaction compared to Korean native adolescents. To consider appropriate interventions, this study investigates the cross-lagged effect between life satisfaction and depression among these adolescents. Secondary data from the Multicultural Adolescents Panel Survey, which is a nationally representative sample, was analyzed. Data from the 3 rd (T1, elementary school), 5 th (T2, middle school), and 7 th

Obesity is a common nutritional disorder in cats and it increases the risk factors for various diseases. The aim of this study is to suggest a method for the evaluation of feline obesity using computed tomography. The attenuation range from -156 to -106 was determined as the range of feline abdominal adipose tissue. With this range, total (TAT), visceral (VAT) and subcutaneous (SAT) adipose tissues were measured. The best correlation between the adipose tissue in cross-sectional image and entire

By integrating these data and conducting a mixed methods analysis, we observed that among the types of social support, network support was a key point for the promotion of social-cognitive factors in increasing exercise adherence. Therefore, network support through SNS-based interventions should be considered as a useful strategy to help vulnerable migrant populations make changes to exercise behaviors.

Trichomonas vaginalis is a pathogen that triggers severe immune responses in hosts. T. vaginalis α-actinin 2, Tvα-actinin 2, has been used to diagnose trichomoniasis. This study was undertaken to examine the role of Tvα-actinin 2 as an antigenic molecule to induce immune responses from humans. Western blot analysis using anti-Tvα-actinin 2 antibodies indicated its presence in the secreted proteins of T. vaginalis. ELISA was employed to measure cytokine production by vaginal epithelial cells, pro

R-Ma Bot's high usability contributed to high retention and behavioral changes, significantly reduced sugar consumption from beverages and improved awareness of nutrition labels. We suggest integrating strategies that enhance knowledge, motivation, and opportunities through BCTs with youth-friendly design elements in the development of interventions for adolescents.

This letter proposes a low-power high-precision capacitance-to-digital converter (CDC) utilizing a dynamic current mirror (DCM) to transform a sensor input capacitance (CIN) into an output current. The resulting current is directly proportional to the ratio of CIN to an internal reference capacitor (CREF) and subsequently converted into a period-modulated output, facilitating simple digitization by a digital counter. The CDC achieves an extensive CIN range of 1 to 68 pF without the need for a po

A 1-year-old intact male Russian blue cat was admitted with a history of depression, partial anorexia, vomiting and dysuria. Through the blood analysis, ultrasonography and urinalysis, this cat was diagnosed as feline lower urinary tract disease with cystitis. Despite antibiotic therapy the cat showed stranguria and urinary catheterization were repeated several times. One week after, this patient appeared depression, hyperthermia and leukocytosis. Ultrasonography revealed a small amount of hypoe

Smart devices incorporating 3D hover or fingerprint sensor require a high-resolution capacitance-to-digital converter (CDC) to detect very small changes in capacitance of only tens of aF [1]. Although the switched-capacitor (SC) delta-sigma (ΔΣ) CDCs have accomplished high resolution [2], [3], the SC ΔΣ CDCs suffer from sampling noise penalty and are prone to an input parasitic capacitor (CP). In addition to the resolution, the CDCs in the systems are designed for low power consumption and small

Intake-based tailored interventions effectively accommodate individual variability in dietary behavior change, with particularly pronounced benefits among participants with higher baseline intake. These findings underscore the importance of adaptive intervention strategies and the need to consider individual and structural factors when designing public health interventions targeting adolescent diet.

This paper proposes that Hopper (1991)s Principle of Persistence can be well observed in the grammaticalization process of the English indefinite article. Persistence is an aspect of grammaticalization in which the traces of a grammaticalized items former lexical meaning are reflected in the constraints on its grammatical distribution. The persistence effect is evident in Present-day English when we look at the distributional constraints of the English indefinite article. The persistent singular
