PURPOSE: The purpose of this study was to identify factors affecting clinical nurses' presenteeism. METHODS: A descriptive cross-sectional design was used in which participants completed self-report questionnaires that consisted of measures for nurses' job satisfaction, job stress, professionalism and presenteeism. 267 nurses working in general hospital participated in this study. Logistic regression analysis was used to estimate predictors of the presenteeism in clinical nurses. RESULTS: 250 nurses experienced one or more health problems last one month. The group who experienced presenteeism during the last one year had significant differences in professionalism and perceived productivity. Predictors of sickness presenteeism in clinical nurses included work experience, total health problem and last 1 year absenteeism. Last 1 year absenteeism and total health problem were strongly related to presenteeism in clinical nurses. CONCLUSION: Major findings of this study indicated that in dealing with nurses' presenteeism, not only managing nurses' job stress and job satisfaction but also providing flexible work schedule and increasing staffing level as an organizational approach are necessary to be considered. Further repeated and expanded research is needed to explore the multidimensional aspects of nurses' presenteeism including a broad range of work setting and the influence of Korean nurses' organizational culture on presenteeism.

PURPOSE: The purpose of this study was to construct and test a structural equation model of quality of work life for clinical nurses based on Peterson and Wilson's Culture-Work-Health model (CWHM). METHODS: A structured questionnaire was completed by 523 clinical nurses to analyze the relationships between concepts of CWHM-organizational culture, social support, employee health, organizational health, and quality of work life. Among these conceptual variables of CWHM, employee health was measured by perceived health status, and organizational health was measured by presenteeism. SPSS21.0 and AMOS 21.0 programs were used to analyze the efficiency of the hypothesized model and calculate the direct and indirect effects of factors affecting quality of work life among clinical nurses. RESULTS: The goodness-of-fit statistics of the final modified hypothetical model are as follows: chi2=586.03, chi2/df=4.19, GFI=.89, AGFI=.85, CFI=.91, TLI=.90, NFI=.89, and RMSEA=.08. The results revealed that organizational culture, social support, organizational health, and employee health accounted for 69% of clinical nurses' quality of work life. CONCLUSION: The major findings of this study indicate that it is essential to create a positive organizational culture and provide adequate organizational support to maintain a balance between the health of clinical nurses and the organization. Further repeated and expanded studies are needed to explore the multidimensional aspects of clinical nurses' quality of work life in Korea, including various factors, such as work environment, work stress, and burnout.

This study aimed to examine the association between body mass index (BMI) and muscle strength, and mobility limitation (ML). A cross-sectional analysis was conducted on data from 570 community-dwelling older Japanese women aged 65-91 years [mean age, 73.9 ± 5.8 (SD) years]. Muscle strength was assessed by hand-grip strength (HGS). ML was assessed using self-reported difficulty level in walking 400 m and ascending 10 steps without resting. BMI and muscle strength were divided into tertiles (high: BMI ≧ 25.1 kg/m², HGS ≧ 22.5 kg; middle: BMI 22.4-25.0 kg/m², HGS 18.8-22.4 kg; low: BMI ≦ 22.3 kg/m², HGS ≦ 18.7 kg) respectively, and logistic regression analysis was used to determine the association between BMI and muscle strength with ML. 256 participants (44.9%) were identified as having ML. Adjusted odds ratios of BMI for ML were 1.64 (95% confidence interval (CI): 1.00-2.68) in the middle group and 1.89 (95% CI: 1.15-3.12) in the high group when compared to the low group. Adjusted odds ratios of muscle strength for ML were 1.25 (95% CI: 0.77-2.04) in the middle group and 1.85 (95% CI: 1.11-3.09) in the low group when compared to the high group. Compared to the low BMI plus high muscle strength group, adjusted odds ratio for ML was significantly higher in the high BMI plus low muscle strength group (2.65, 95% CI: 1.02-6.87) and the high BMI plus middle muscle strength group (3.09, 95% CI: 1.25-7.61). Our findings indicate that the combination of overweight plus muscle weakness is more predictive for having ML than overweight or muscle weakness alone.

PURPOSE: The purpose of this study was to identify the knowledge structure of Asian Oncology Nursing (AON) from 2002 to 2018.METHODS: Abstracts from 382 studies were reviewed and analyzed using the text network analysis program, NetMiner 4.3. Keywords network trends were compared before and after 2012 when the journal title changed from Journal of Korean Oncology Nursing to Journal of Asian Oncology Nursing.RESULTS: ‘Cancer,’ ‘patient,’ ‘quality of life,’ ‘breast,’ ‘nurse,’ ‘depression,’ ‘health,’ ‘nursing,’ ‘pain,’ ‘family’ were the top 10 most frequent keywords, and ‘cancer,’ ‘patient,’ ‘quality of life,’ ‘health,’ ‘nursing,’ ‘family,’ ‘intervention,’ ‘effect,’ ‘hospital,’ and ‘therapy’ were the dominant keywords that ranked highest in co-appearance frequency. Core keywords changed before and after 2012. After 2012, depression, health, symptom and pain were the keywords ranked that replaced nursing, education, family, and intervention from before 2012. Four subtopic groups were identified: 1) cancer treatment, education and information, 2) chemotherapy and psychological adjustment, 3) psychosocial adjustment of cancer survivors, and 4) process of cancer intervention and support.CONCLUSION: This study provides a general overview of research trends of the Asian Oncology Nursing Society. Findings of this study may guide future research directions in Asian Oncology Nursing research.

OBJECTIVE: The Delirium Motor Subtype Scale (DMSS) is a validated and reliable instrument developed from various methods previously used to assess delirium motor subtypes. It focuses on pure motor disturbances with a relative specificity for delirium. The aim of this study was to investigate the validity and reliability of a Korean version of the DMSS (K-DMSS). METHODS: We recruited 145 patients who were older than 60 years and had been referred for psychiatric consultation for delirium. These patients were evaluated using the K-DMSS, Liptzin & Levkoff criteria, and the Korean version of the Delirium Rating Scale-Revised-98 (K-DRS-R98) to compare delirium motor subtypes. RESULTS: The internal consistency of the K-DMSS in assessing delirium motor subtypes was acceptable (Cronbach's alpha=0.79). Delirium motor subtypes identified with the K-DMSS and K-DRS-R98 showed almost perfect agreement (Cohen's Kappa=0.81), while those identified with the K-DMSS and Liptzin & Levkoff criteria showed substantial agreement (Cohen's Kappa=0.78). CONCLUSION: Our results suggest that the K-DMSS is a valid and reliable tool for identifying delirium subtypes.

Habitual moderate- to vigorous-intensity physical activity positively impacts lower extremely performance in older adults. However, little is known whether habitual sedentary behaviour time independently impacts lower extremity performance. The purpose of this cross-sectional study was to identify whether sedentary behaviour time is associated with lower extremity performance independent of moderate- to vigorous-intensity physical activity time in older adults. Eight-hundred-and-two community-dwelling older Japanese adults (72.5 ± 5.9 years) participated in this study. Sedentary behavioir time and moderate- to vigorous-intensity physical activity time were assessed using a uniaxial accelerometer. Lower extremity performance was assessed by repeated chair stand, single leg stance, and timed up and go tests. Jonckheere terpstra trend test and Spearman rank correlation coefficient were used to identify the single relation between sedentary behaviour time and lower extremity performance. A hierarchical multiple regression analysis was used to identify whether sedentary behaviour time is associated with lower extremity performance independent of moderate- to vigorous-intensity physical activity time. Results of single relation analysis showed there were negative associations between sedentary behaviour time and all lower extremity performance tests. Multivariable analysis indicated that sedentary behaviour time was not significantly associated with any lower extremity performances but moderate- to vigorous-intensity physical activity time was positively associated with all lower extremity performance tests. In conclusion, sedentary behaviour time would be less useful than moderate- to vigorous-intensity physical activity time as an indicator for modifying habitual behavior to maintain good lower extremity performance in community-dwelling older adults.

The purpose of this study was to examine the association between objective measures of sleep quality and obesity in older community-dwelling people. This cross-sectional study included 189 community-dwelling adults aged > or = 80 yr (83.4 +/- 2.5 yr [age range, 80-95 yr]). Participants wore an accelerometer (ActiGraph GT3X+) on their non-dominant wrist 24 hr per day for 7 consecutive nights. Sleep parameters measured included total sleep time, sleep efficiency, and wake after sleep onset (WASO) during the night. Associations between sleep parameters and obesity were investigated by using multivariate logistic regression analysis. In multivariate models, those with sleep efficiency lower than 85% had a 2.85-fold increased odds of obesity, compared with those with sleep efficiency of 85% or higher. Similarly, those with WASO of > or = 60 min (compared with < 60 min) had a 3.13-fold increased odds of obesity. However, there were no significant associations between total sleep time or self-reported napping duration and obesity. We found that poor sleep quality was an independent risk factor for obesity in community-dwelling Japanese adults aged > or = 80 yr, even after controlling for potential confounding factors, including daily physical activity.

PURPOSE: The purpose of this study was to identify a research trend of studies related to the Do-Not-Resuscitate (DNR) decision making process in Korea. METHODS: Assessing through five computerized databases, 889 studies were reviewed and of these 32 were included. An integrative literature review and text network analysis were applied to examine the research. The keywords from each article's abstracts were extracted by using a program, KrKwic. RESULTS: The number of studies on DNR decision has been increasing, especially since 2011. A descriptive study design (59%) was most commonly used in the research. In relation to factors affecting DNR decision, 97% of the studies stated patient factors and 66% stated family factors. 'Patient', 'DNR', 'decision', 'treatment', 'life', 'family' were the major keywords, and 'patient' and 'care' were dominant keywords that ranked high in coappearance frequency. CONCLUSION: Studies related to DNR decision have been increasing, and themes of the studies have also been broader. Further research is required to investigate factors affecting DNR decision in specific populations such as cancer patients, the elderly, patients with end-stage of chronic diseases etc. Moreover, a comparative study is necessary to define differences of research trends related to DNR decision making process between Korea and other countries.

BACKGROUND: The purpose of this study was to explore the optimal cut-off point of calf circumference (CC) as a simple proxy marker of appendicular skeletal muscle mass (ASM) and sarcopenia in the Korean elderly and to test the criterion-related validity of CC by analyzing its relationships with the physical function. METHODS: The participants were 657 adults aged 70 to 84 years who had completed both dual energy X-ray absorptiometry (DXA) and physical function test in the first baseline year of the Korean Frailty and Aging Cohort Study. RESULTS: ASM and skeletal muscle mass index (SMI) were correlated positively with CC (male, ASM, r = 0.55 and SMI, r = 0.54; female, ASM, r = 0.55 and SMI, r = 0.42; all P < 0.001). Testing the validity of CC as a proxy marker for low muscle mass, an area under the curve (AUC) of 0.81 for males and 0.72 for females were found and their optimal cut-off values of CC were 35 cm for males and 33 cm for females. In addition, CC-based low muscle groups were correlated with physical functions even after adjusting for age and body mass index. Also, the cut-off value of CC for sarcopenia was 32 cm (AUC; male, 0.82 and female, 0.72). CONCLUSION: The optimal cut-off values of CC for low MM are 35 cm for males and 33 cm for females. Lower CC based on these cut-off values is related with poor physical function. CC may be also a good indicator of sarcopenia in Korean elderly.
