Abstract Background There has been little research regarding nursing teamwork, despite its important role in multidisciplinary teamwork healthcare settings and significance ensuring high-quality care. This study aimed to determine the levels of Korean nurses examine relationship between patient-centered care while controlling for other individual work-related factors. Methods We conducted a cross-sectional analysis online survey data. The population consisted 992 registered employed...
Suicide rates in the United States have increased steadily over past twenty years, a trend coinciding with rising use of mental health services across country. To help patients before suicide attempt, systems must be able to screen for risk and take action at large scale. Recently, powerful machine learning (ML) models emerged that can accurately predict attempts by using historical electronic record (EHR) data, yet there exists no standardized framework implementing these care delivery....
We aimed to investigate the effect of internet-based and in-person cognitive interventions on cognition, mood, activities daily living (ADL) patients with mild moderate Alzheimer's disease (AD) examine whether intervention is as effective intervention. recruited 52 probable AD, whom 42 completed trial. randomly divided participants into control groups at a 1:1 ratio statistically compared neuropsychological test results two groups. In addition, in group were assigned 4 weeks or intervention,...
Enhancing nursing teamwork benefits both patients and nurses. The Nursing Teamwork Survey is a reliable, valid tool to evaluate teamwork. This study was conducted translate psychometrically validate the for nurses in Korea. In Phase 1, translated into Korean using forward backward translations. Content face validity were determined expert review pilot testing, respectively. 2, we evaluated construct convergent internal consistency, test-retest reliability. We used survey data from 1119...
4‐Amino‐ N ‐hexadecylbenzamide‐graphene sheets (AHB‐GSs), used in the preparation of polyimide (PI) nanocomposite films, were synthesized by mixing a dispersion graphite oxide with solution ammonium salt AHB. The atomic force microscopy image AHB‐GSs on mica and profile plot revealed average sheet thickness to be ~3.21 nm. PI films prepared reacting 4,4'‐biphthalic anhydride bis(4‐aminophenyl) sulfide. containing different amounts AHB‐GS (0–10 wt%) compared for their morphologies, thermal...
Poly(amic acid) (PAA) was prepared by the reaction of 4,4′-(hexafluoro isopropylidene) diphthalic anhydride with 2,2′-bis(trifluoromethyl) benzidine in N, N-dimethylacetamide. Hybrid films were obtained from blended solutions precursor polymer and saponite (SPT) or organically modified hectorite (STN) clays, clay content varied 0 to 40 wt%. The cast film PAA heat treated at different temperatures create polyimide (PI) hybrid films. nanostructure observed using transmission electron...
폴리이미드(PI) 나노복합체 필름 제조에 사용된 작용기화 4-amino-N-hexadecylbenzamide graphene sheets (AHB-GSs)는 oxide 분산액에 4-amino-N-hexadecylbenzamide(AHB)를 반응시켜 합성하였다. AHB-GS의 주사탐침 현미경(atomic force microscope, AFM) 이미지와 모식도를 통해서 평균 두께가 약 3.21 nm임을 확인하였다. PI는 4,4'-biphthalic anhydride와 bis(4-aminophenyl)sulfide를 사용하여 PI 나노복합체는 0-10 wt%의 다양한 함량의 AHB-GS를 용액 삽입(solution intercalation) 방법을 합성하였고, 이미드화는 각각 <TEX>$250^{\circ}C$</TEX> 및 <TEX>$350^{\circ}C$</TEX>까지 열 처리하였다. AHB-GS는 대부분 고분자 매트릭스에 잘 분산되었고 약간 뭉친 것도 있었지만...
4,4'-Biphthalic anhydride(BPA)와 2,2'-bis(trifluoromethyl) benzidine(TFB)의 구조에 서로 다른 무수물인 4,4'-(hexafluoroisopropylidene) diphthalic anhydride(6FDA)와 1,2,4,5-benzentetra carboxylic dianhydride(pyromellitic dianhydride) (PMDA)를 각각 반응시켜 열적 및 화학적 이미드화 반응을 통해 두 가지 시리즈의 폴리이미드 공중합체(copolyimide, Co-PI)를 합성하였다. 합성한 Co-PI를 무수물 단량체의 조성에 따라 성질 광학적 투명성을 비교 분석하였다. 성질을 증가시키기 위해서는 6FDA보다는 PMDA가 더 효과적이었으나, 광학 투명성에서는 오히려 6FDA가 효과적이었다. Two series of copolyimides (Co-PIs) were prepared by reacting anhydride...
Trimellitic anhydride chloride와 2,7-dihydroxynaphthalene을 이용하여 2,7-dihydroxynaphthalene bis(trimellitate anhydride) (2,7-TA)의 무수물 단량체를 합성하였다. 합성된 2,7-TA와 p-xylylenediamine 및 2,2'-bis(trifluoromethyl) benzidine(TFB)을 다양한 몰 비로 반응하여 얻은 폴리아믹산(polyamic acid, PAA)을 유리판에서 열처리하여 에스터기를 가지는 폴리이미드 공중합체(copolyimide, Co-PI)를 Co-PI는 TFB의 비 조성에 따라 열적 성질, 가스 투과도, 광학 성질 등을 조사하였다. 용액 캐스팅으로 Co-PI 필름은 유연하고 질긴 성질을 보였다. 모두 투명하였으며, 각 필름의 cut-off wavelength은 370~395 nm이었고, 노란색 지수는 3.55~7.63의 비교적 낮은 값을 보여주었다. 성질들은...
Purpose: This study aimed to investigate the relationships between characteristics of nursesâ work schedules, health outcomes, and work-life balance. Methods: was a secondary data analysis that included 422 nurses in Korean hospitals. Descriptive analysis, independent sample t-test, one-way ANOVA, Pearson correlation multiple linear regression were used identify associated factors. Results: Multiple showed balance lower when atypical performed (β=-.14, p=.010). Nurses who did not overtime...
