조민정,하영미 한국지역사회간호학회 2019 지역사회간호학회지 Vol.30 No.1

Purpose: The purpose of this study was to develop an instrument for measuring nursing information literacy competency, and then to examine the validity and reliability of the instrument. Methods: The developmental process of the instrument includes construction of a conceptual framework, generation of initial items, verification of content validity, preliminary study, extraction of final items, and psychometric testing. Its content validity was verified by three experts from nursing and nursing informatics. Its construct, convergent, and discriminant validity was examined in confirmatory factor analysis. Finally, its criterion validity was measured with Pearson’s correlation. The tool’s reliability was examined by Cronbach's ⍺. The participants include 382 nurses from four hospitals and one university hospital. Results: Twenty seven items in total were selected for the final scale, and the results of the confirmatory factor analysis were supported with acceptable model fit, which were named competency for identifying problem, potential sources for information, searching fine information, evaluating information, acquising and managing of information, using information ethically, and integrating new information. The convergent, discriminant and criterion validities were also supported. The Cronbach's ⍺ coefficient was .93. Conclusion: The instrument is valid and reliable to comprehensively assess nurses' information literacy competency, and to provide a basic direction for developing nursing information literacy program.

Heterotopic mesenteric ossification is a very uncommon disorder that is characterized by new bone formation in the mesentery, which does not normally undergo ossification. A 52-year-old female experienced a small bowel obstruction 12 days after a segmental resection of the small bowel following a trauma. A laparotomy was performed 16 days after the initial operation, and a 2 cm hard mass was detected in the small bowel mesentery, with severe fibrous adhesions around the mass, involving the jejunum, which required resection. Postoperatively, the patient developed an intraabdominal abscess, followed by intestinal fistulation. The patient gradually recovered by conservative management, and left hospital 70 days after the first operation. Microscopic examination of the mass showed well oriented trabeculae of the osseous tissue, osteoid formation, with fine calcification and osteoblastic activity, but there was no formation of mature lamellar bone or clear evidence of the "zone phenomenon" that is classically described in heterotopic ossification. These findings appeared consistent with an early stage of heterotopic ossification. The etiology and pathogenesis are unknown; the heterotopic mesenteric ossification was thought to be associated with the trauma (intraabdominal surgery). The previous literature on heterotopic mesenteric ossification is reviewed, and a new case reported. (J Korean Surg Soc 2003;65:361-365)

조민정,천종애 대한예방치과학회 2013 International Journal of Clinical Preventive Denti Vol.9 No.3

The aim of this study was to evaluate dentinal tubule occlusion efficacy and safety of dentifrice containing nano sized Hydroxy Apatite for rabbit. Methods: Subjects of this study were 15 of 14-weeks old male New Zealand white rabbits. For the study, rabbits were divided two groups of 7 and 14 day treatment. Upper and lower 4 incisors, totally 60 teeth were used for this experiment. Experiment dentifrice 1 and 2 are prepared by containing 2% and 8% nano sized Hydeoxy Apatite respectively. For positive control, on-sale anti-hypersensitivity dentifrice which containing 19% of micro sized Hydroxy Apatite was used. Negative control was distilled water. For the safety evaluation, microscopic observation was performed for sacrificed rabbit’s gingival tissue. Results: 1. Experimental 1, 2 and positive control dentifrice showed dentinal tubule occlusion efficacy (p<0.001) and 14days treated experiment 1 and 2 groups showed higher occlusion effect than 7 days treatment (p<0.01). 2. After 7 days treatment,experiment 1 and 2 dentifrice showed more effective dentinal tubule occlusion property than positive control dentifrice (p<0.001). There is no significant difference between groups of experiment 1 and 2. 3. After 14-days treatment, dentinal tubule occlusion efficacy was higher in orderly experiment 2, experiment 1 and positive control dentifrice (p<0.001). 4. Any inflammation could not be found for all experimental gingival tissue samples. Conclusion: Dentifrice containing nano-HAP showed higher dentinal tubule occlusion efficacy for rabbit than micro-HAP contained dentifrice. Dentinal tubule occlusion effect increased by nano-HAP content and treatment period. Dentifrice containing nano-HAP was safe for gingival tissue of rabbits.

Stair climbing is a form of physical activity that can be easily accessible in worksites and public settings, but it remains unclear whether stair climbing exercise is more effective in improving vascular health than walking exercise. The aim of this study was to compare the short-term effects of stair climbing exercise and walking exercise on vascular function in healthy young adults. Eighteen healthy adults were randomized to either the stair climbing exercise group (n=10) or the walking exercise group (n=8). The stair climbing exercise was performed inside a building, while the walking exercise involved a brisk walking exercise on the treadmill at the same exercise intensity (50-60% of heart rate reserve) for 2 weeks, 30 min/day, and 3 times/week. Peak oxygen uptake was measured by maximal cardiopulmonary exercise test. Carotid-femoral pulse wave velocity (c-f PWV) and flow-mediated dilation (FMD) as indexes of vascular function were measured using applanation tonometry and ultrasound machine, respectively. These variables were measured at baseline and again after 2 weeks of supervised exercise in both groups. FMD improved similarly in both groups (stair climbing: 11.5±2.2 to 14.3±2.4%, walking: 10.8±1.3 to 12.1±2.9%, time effect: p<0.05). However, an improvement in c-f PWV did not reach statistical significance in both groups (stair climbing: 6.83±0.8 to 6.40±0.88 m/s, walking: 6.61±0.8 to 6.46±0.85 m/s, p=0.051). No changes in peak oxygen uptake were observed in any group (stair climbing: 35.47±7.83 to 37.03±8.26 mL/kg/min, walking: 37.46±5.21 to 38.33±6.73 mL.kg/min, p=0.726). These findings suggest that both short-term stair climbing and treadmill walking exercises were comparatively effective in improving conduit artery endothelial function in healthy young adults.

Objectives: This study was conducted to develop a smartphone application (app) as an educational learning instrument for coronary artery disease (CAD) patients and to assess the users’ level of satisfaction. Methods: This methodological research involves elicited learning content for CAD patients to develop a learning instrument using the smartphone app. The app was developed according to the steps of Assessment, Design, Development, Implementation, and Evaluation, which is a systematic instructional design model. The levels of satisfaction with the developed smartphone app among 30 outpatients with CAD were assessed via a questionnaire during their visits to a cardiology outpatient department. Results: A smartphone app ‘Strong Heart’ was developed through reviewing the literature associated with education for CAD patients under professional supervision and searching for medical smartphone apps that are already available. The learning contents include six main sections containing essential learning issues in managing CAD and additional information to attract the user’s attention, such as patient cases and quizzes. After modification with feedback from experts, the app was finally developed and evaluated by patients who reported that they were satisfied with the usefulness of the app. Conclusions: The developed smartphone app is available on both the iPhone App Store and the Android Play Store. Patients with CAD may utilize the app for supporting educational material without limitations of time and space.
