강현욱,이지훈,박준범,문주혁 한국콘크리트학회 2024 International Journal of Concrete Structures and M Vol.18 No.3

Although clinker has been used for many years, complicated mineralogical properties of clinker pose challenges for the precise quantification. In this study, the mineralogical and crystallographic properties of nine different clinkers according to grinding procedures were investigated. With the dry-grinding for 2 h, particle size reduction to 3 μm of median particle size with a substantial phase transition to an amorphous phase observed, to which alite (C3S) mainly contributed to the transition. Meanwhile, the crystallographic properties of the clinker phases were barely changed during the wet-grinding. In the wet-grinding program, the amount of ferrite solid solution (C4AF) with a high linear absorption coefficient was not underestimated. Furthermore, well-corrected preferred orientation effect on C3S was positively contributed to the analysis result of clinkers with the wet-grinding. Hence, it was suggested that the crystallographic effects observed in the wet-grinding program could produce more reliable results in phase analysis for the clinkers.

Geriatric Hospital Nurses' Perceived Barriers to Research Utilization and Empowerment

강현욱 한국간호과학회 2015 Asian Nursing Research Vol.9 No.1

Purpose: The quality of nursing care in geriatric hospitals has been of concern. Nurses need to provide evidence-based nursing using best available research findings in order to maximize the quality of care. Research utilization is a major part of evidence-based nursing practice. Empowerment is an important factor that may influence the context of nursing practice. The purpose of this study was to identify the barriers to research utilization in nursing practice and its relationship to empowerment perceived by registered nurses (RNs) in geriatric hospitals. Methods: A descriptive, correlational design was used. A total of 147 RNs from six geriatric hospitals in K province of Korea participated. The BARRIERS scale and the Conditions of Work Empowerment Questionnaire-II were administered to identify perceived barriers to the use of research findings and the level of perceived empowerment respectively. Results: Participants rated that research reports being written in English constituted the greatest barrier to the use of research findings. The score was the highest for the Communication domain, suggesting the greatest barrier, and the lowest for the Adopter domain. Subscales of the Conditions of Work Empowerment Questionnaire-II were significant predictors of the Adopter, Organization, and Communication domains of the BARRIERS scale. Conclusions: This study found that RNs in geriatric hospitals perceived that interpreting and understanding research reports in English was the greatest barrier to the use of research findings. Administrators and nurse managers of geriatric hospitals need to provide RNs with opportunities to participate in research-related activities and to empower RNs in order to facilitate research utilization.

We described the effects of antioxidant activity on the extracts of tissue and callus formation by Ligularia fisheri . The callus culture was induced from leaf tissue of Ligularia fisheri in both MS and B5 medium with IAA(0∼1.5 ㎎/ℓ) or/and kinetin (0∼1.0 ㎎/ℓ). As medium for callus culture induced from Ligularia fisheri , B5 and MS medium showed no callus formation. Both media brought to decrease differentiation of callus, on the other hand those induced to accelerate cell development. The hytohormones were required over 0.4 ㎎/ℓ of IAA and kinetin for formation of callus and those conditions were induced the pigmental deposit like dark red color in callus tissue. In order to extract functional material from natural leaf and callus tissue of Ligularia fisheri used distilled water and 75% ethanol as solvent and those extract used to determine antioxidant activity as 1, 1-diphenyl-2-picryl-hydrozyl (DPPH) radicals scavenging effect and TBA(thiobarbituric acid) activity as well as the concentration of total phenol and flavonoid. In result, the effect of DPPH and TBA had high activity more callus extract of red color than callus(green color) and natural leaf tissue and it also had high concentration of flavonoid. That is because the high concentration of phytohormone brought stress tolerance and hypersensitivity in callus tissue of Ligularia fisheri , so this reaction induced to change color of callus tissue like pigment deposit for culture.

The goal of this study is to examine the qualities of historical inquiry activities in the middle school history textbooks in use and to provide evaluation criteria as well as production guidelines for better activities. To achieve the goal, we began to analyze the current history textbook activities based on the operational definition of historical inquiry as a process in which student understand and experience inquiry methods as historians do in parts or in whole. The analysis results include that the various subject and content of historical inquiry activities appear to be presented appropriately although a number of activities fail for students to engage in historical inquiry process. To enhance the quality of historical inquiry activities in history textbooks, we provide several suggestions regarding meaningful queries for active historical interpretation and activity composition with which students’ experience should be organized in terms of the intention, aims and processes of the historical inquiry. Furthermore, the use of non-textual materials should be incorporated in activities for students to involve in diverse forms of inquiry materials.

Objectives: Frailty has been associated with increased mortality and treatment or surgical complications in elderly patients with cancer. The purpose of this study was to identify sex differences in the predictors of frailty in elderly patients with cancer. Methods: This was a cross-sectional, descriptive study using data from the 4th Survey of Living Conditions of Elderly study conducted in 2017. Data of the elderly diagnosed with cancer were used for the analyses. Using the FRAIL scale, participants were classified into robust, prefrail, and frail groups. Results: Among the 391 participants with cancer (203 men and 188 women), the prevalence of frailty was found to be 24.6% and 32.4% in men and women, respectively. The predictors of frailty in men were low physical activity, dependency for instrumental activities of daily living (IADLs), depression, and body mass index. The predictors in women included low physical activity, dependency for IADLs and old age. Conclusions: The predictors of frailty differed by sex. Frailty programs tailored to address different predictors may effectively prevent or delay the progression of frailty in elderly patients with cancer.
