Purpose: The aim of this study was to identify the factors influencing ICU (intensive care units) length of stay of adult patients with critical illness. Methods: This study was adopted descriptive design. 270 patients who were admitted to ICU in general hospital, Seoul were analyzed. Results: A total of 270 patients, 116 (43%) patients had stayed more than 5 days. The length of stay of intensive care unit was significant positive correlation with the FCI(Functional Comobidity Index) score(r=0.33, p<.001) and APACHE(Aacute Physiology and Chronic Health Evlauaion) II(r=0.19, p=.001). In multiple logistic regression, the predictors of ICU length of stay were admission route (p=0.013), FCI score (p<0.001), APACHE II(p=0.012). Conclusions: Heatlh care providers in ICU should be aware that patients who admit to emergency departments and have higher disease severity are more considered to reduce their ICU length of stays.

This study examined the association of gait variability and physical fitness with frailty status in older women. In a cross-sectional design, 168 elderly women, aged 65 years and older (75.07±5.40 years), measured body composition, gait parameters gait variability, physical fitness variables, MMSE-DS and CES-D. Subjects were classified as robust, pre-frail, and frailty based on the Fried et al.(2001) criteria for frailty weight loss, exhaustion, low hand-grip strength, low gait speed, and physical inactivity. Logistic regression analyses were used to determine the odds ratio (ORs) and 95% confidence interval (CI) of frailty status for having gait variability and physical fitness levels. Compared to the robust group (OR=1), the frailty group had significantly higher ORs of having terminal double limb stance (OR=1.48, 95% CI=0.10-2.21, p=.049), step cadence (OR=2.06, 95%CI=1.20-3.43, p=.009) variability, and significantly lower ORs of having upper-strength (OR=0.49, 95%CI=0.31-0.77, p=.002) even after adjusting for age, education, comorbidity, K-IADL, MMSE-KC and CES-D score. The finding of this study suggested that terminal double limb stance, step cadence and upper body muscular strength were independent predictors of frailty.

In predicting vascular disease, this study attempted to identify changes in the carotid intima-media thickness in patients who underwent carotid artery ultrasonography and hematological tests and to find out the effect of risk factors on the expression of atherosclerotic plaque. A retrospective analysis was conducted on 469 healthy adults who visited the hospital for the purpose of medical examination and performed carotid artery ultrasonography. As a result, carotid intima-media thickness, age, body mass index, waist circumference, systolic blood pressure, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and glucose were analyzed as significant predictors of atherosclerotic plaque (p<0.001). The risk ratio was calculated based on the cut off value of the risk factors of the atherosclerotic plaque determined through ROC curve analysis, followed by 8.06 times the carotid intima-media thickness, 7.53 times the age, 3.97 times the waist circumference and 2.02 times the glucose. Therefore, in this study it was possible to prepare a Korean standard for clinical risk factors that affect the presence of absence of atherosclerotic plaque and observation of carotid artery ultrasonography is thought to help diagnose or predict cardiovascular disease early.

This study was a descriptive survey study for nursing college students to identify disaster awareness, attitude, disaster preparation, nursing professionals, social support, and disaster nursing capabilities, and to prepare measures to improve disaster nursing capabilities by identifying predictors of disaster nursing capabilities. Data collection was collected from 160 nursing students in G-do from March 27 to April 7, 2023, and a total of 158 copies were finally analyzed. Using the SPSS Win. 25.0 program, technical statistics, t-test, one-way ANOVA, Pearson correlation coefficient, and hierarchical multiple regression were analyzed. The result show that fourth grade(β=.20, p=.027), disaster nursing education is 'existent'(β=.15, p=.041), disaster readiness(β=.27, p<.001) nursing professional(β=.21, p=.012) was found to be a significant predictor of disaster nursing competency. Disaster preparation was found to be the best predictor of disaster nursing competency, followed by "nursing professionals," "fourth grade," and "disaster nursing education" with 26.3% of explanatory power. According to the findings of this study, it is necessary to develop an integrated education program for disaster nursing practice that can enhance awareness of disasters, attitudes toward disasters, disaster preparation, nursing professionals, and social support.

The Artificial Neural Network (ANN) model was suggested for predicting probability of precipitation (PoP) using RDAPS NWP model, observation at AWS and upper-air sounding station. The prediction work was implemented for flood season and the data period is the July, August of 2001 and June of 2002. Neural network input variables (predictors) were composed of geopotential height 500/750/1000 hPa, atmospheric thickness 500-1000 hPa, X & Y-component of wind at 500 hPa, X & Y-component of wind at 750 hPa, wind speed at surface, temperature at 500/750 hPa/surface, mean sea level pressure, 3-hr accumulated precipitation, occurrence of observed precipitation, precipitation accumulated in 6 & 12 hrs previous to RDAPS run, precipitation occurrence in 6 & 12 hrs previous to RDAPS run, relative humidity measured 0 & 12 hrs before RDAPS run, precipitable water measured 0 & 12 hrs before RDAPS run, precipitable water difference in 12 hrs previous to RDAPS run. The suggested ANN has a 3-layer perceptron (multi layer perceptron; MLP) and back-propagation learning algorithm. The result shows that there were 6.8% increase in Hit rate (H), especially 99.2% and 148.1% increase in Threat Score (TS) and Probability of Detection (POD). It illustrates that the suggested ANN model can be a useful tool for predicting rainfall event prediction. The Kuipers Skill Score (KSS) was increased 92.8%, which the ANN model improves the rainfall occurrence prediction over RDAPS.

This study examined BMI distributions among older adults in three different countries: the U.S., Japan, and Korea. The paper also explored differences in the factors predicting BMI in the three countries using three data sets: the U.S. Longitudinal Study of Aging (LSOA II, 8,589 persons), the Nihon University Japanese Longitudinal Study of Aging (NUJLSOA, 2,888 persons), and the Korean Longitudinal Study of Ageing (KLoSA, 2,397 persons). Descriptive analysis and multiple regression were performed. Japanese older adults were somewhat lighter than Koreans with fewer people at the upper end of the BMI distribution. Distributions of BMI among both Koreans and Japanese are shifted leftward relative to Americans. There is less dispersion in the distribution of BMI for Koreans and Japanese than among Americans. The association between socioeconomic variables and BMI is stronger in the U.S. and Japan than in Korea. Demographic variables are strong predictors of BMI in Korea. In Japan, all health behaviors have significant effects on BMI. It is concluded that the relationships between behavioral, demographical, and socioeconomic factors and BMI are not the same across countries. Results have policy implications for the involvement of health practitioners in helping older adults to control weight.

Background: Falls are among the most common and serious health problems of older people. The psychological symptoms of falling have received relatively little attention compared to physical problems. Objective: The purpose of this study is to test a model to explain the factors that influence fear of falling among older adults living in a continuing care retirement community (CCRC) in Baltimore city, United States. Methods: A secondary analysis was conducted using data obtained from a Health Promotion Survey done on 149 older adults living in a CCRC. Data was originally obtained during face to face interviews with each participant. Descriptive statistics and bivariate correlations were used to describe the sample and evaluate simple correlations. A path analysis was done using the AMOS 4.0 statistical program. Results: Of the 49 hypothesized paths, 13 were statistically significant, and the model accounted for 22% of the variance in fear of falling among the elderly. There was support for the fit of the model to the data with a nonsignificant chi square at 0.478 (df=2, p=0.79), and the ratio of chi-square to degrees of freedom was 0.24, a CFI of 0.99 and RMSEA of 0.00. In particular, gender, a history of falling, and exercise were significant predictors of fear of falling. Conclusions/Implications: As anticipated, exercise is an important factor to prevent fear of falling. As a modifiable variable, self-efficacy and outcome expectation indirectly influence fear of falling through exercise.

Recently, an interest on parenting stress and depression of grandparents raising grandchildren is rising according to the increase of working couple and divorce. Discussing around developmental task of elderly, one of the influencing factors on increase of grandparents' parenting stress and depression is leisure restriction. However, this factor has received far less rigorous analysis. Thus, the purpose of this article is to offer an analysis of the effect of leisure activities on depression in grandparents raising grandchildren. The data was collected from 172 grandparents raising their grandchildren in 2011 national survey results on the elderly life conditions. Their analyses were composed of descriptive statistic and multiple regression analysis. The study generated several findings. First, grandparents participated in activities for exercise and religion at a high rate and their mean score of depression was 7.1 of 15 what suggests middle level of depression. second, multiple regression analysis showed that the factor of exercise, travel experience, leisure activities satisfaction and other special leisure activities were statistically significant predictors of depression. Implication for social welfare services and programs to improve the mental health of grandparents raising their grandchildren to have positive self-awareness and attitude about life in their position and living condition for help prevent depression were discussed.

The purpose of this study is to describe how the structural and functional features of social network change among widowed middle and older adults and to examine the effect of personal predictors of the social network change. Data was obtained from men and women between 45 to 98 years of age(N=118) who were bereaved by the death of their spouse since the first wave survey and participated in the second wave survey of the Korean Longitudinal Study of Ageing(KLoSA). The main findings are as follows: First, their social network after the bereavement was strengthened centered around children; for example, the number of adult children living in proximity to the parent, frequency of contact with children, and the financial and non-financial support from children generally increased. Second, the social network change pattern was categorized into four types such as "overall increased type," "children-centered increased type," "children/close relationship-centered increased type," and "stagnation type." Finally, the health condition of the widowed middle and older adults was a strong predictor of the social network change.

This study aims to explore how the individual characteristics of the senior job placement project coordinators and the organizational structure in which they work affect their job performance. A survey of 251 coordinators who were working in the senior job placement project agencies were retrieved and used for empirical analysis using the SPSS Win.12 program. The result shows that a sense of self efficacy, the individual traits(understanding of the senior job placement project, attitude towards the elderly) and the organizational structure(the level of formalization of agency) were statistically significant predictors of the level of job performance. The results of this study show that the coordinators who were more confident about themselves, who had more understanding about the senior job placement project, who had more positive attitude towards the social activities of the elderly, and who were working in agencies with higher level of formalization had a higher level of job performance than their counterparts. Therefore, more policy and program considerations should be taken into account in empowering the coordinators, and in providing them with standardized organizational process. This in turn will ultimately enable them to better serve the elderly who participate in the senior job placement projects.
