Purpose: The purpose of this study was to investigate the effects of exercise intention, exercise habit, exercise self-efficacy on exercise behavior with elders at welfare center. Methods: The subjects were 152 elders at the welfare center at J city. Data were collected using the questionnaires which consisted of the Exercise intention scale and the Exercise habit scale developed by Lee and Gu (2018), and the Exercise self-efficacy scale developed by Lee and Chang (2001). The collected data were analyzed with the SPSS/WIN 22.0 program, which was used for frequency, percentage, mean, standard deviation, x² test, and multiple logistic regression. Results: The regular exercise group consisted of 92 elders (62.5%) and the irregular exercise group of 60 elders (39.5%). The scores for exercise intention, exercise habits, exercise self-efficacy were 3.28±0.70, 3.92±0.61, 2.80±0.88 in regular exercise group, and 2.38±0.99, 3.00±1.07, 2.04±0.73 in irregular exercise group, respectively. Two groups were significantly different between the two groups. Multiple logistic regression analysis showed that exercise intention (OR: 2.26, 95% CI:1.19~4.28), exercise habits (OR: 1.79, 95% CI:1.01~3.15), exercise self-efficacy (OR: 1.99, 95% CI:1.11~3.57) were affecting factors for regular exercise in elders. Conclusion: To increase the regular exercise behaviors of the elderly at the welfare center, it is needed the strategies to increase exercise intention, exercise self-efficacy, and exercise habits.

Objectives : This study was conducted to investigate the current status of outsourcing in Korean hospital information systems and the factors influencing its introduction. Methods : The authors surveyed 136 hospitals located in Seoul and its surrounding vicinities from June 7 to June 23, 2006. The facilitators and inhibitors to outsourcing in hospital information systems were derived from literature and expert reviews. Multiple logistic regression analysis was applied to identify the major influencing factors on outsourcing in hospital information systems. Results : Eighty-six (63.2%) of the 136 hospitals surveyed, which were mainly tertiary hospitals, responded to using outsourcing for their hospital information systems. "Hardware and software maintenance and support," "application development," and "management of service and staff" were the major areas of outsourcing. Outsourcing had been employed for $4\sim7$ years by 45.5% of the hospitals and the proportion of the budget used for outsourcing was less than 20%. A need for an extension in outsourcing was agreed on by 76.5% of the hospitals. The multiple logistic regression analysis showed that both consumer satisfaction and security risk have an influence on hospital information system outsourcing. Conclusions : Outsourcing in hospital information systems is expected to increase just as in other industries. One primary facilitator to outsourcing in other industries is consumer satisfaction. We found that this was also a facilitator to outsourcing in hospital information systems. Security risk, which is usually considered an inhibitor to information technology outsourcing, was proven to be an inhibitor here as well. The results of this study may help hospital information systems establish a strategy and management plan for outsourcing.

Objectives: This study was performed to provide the basic data for establishing countermeasures for preventing injury by analyzing the incidence rates, the risk factors, the characteristics of the injury and the utilization of medical care for mild injury that lasted for two weeks. Methods: We examined the injury survey data among the National Health and Nutrition Survey data. The definition of mild injury that lasted for two weeks was that the injury that caused pain at least once a day for two weeks or the injury for which the usual daily activity of the injured person was severely affected. We used statistical analysis methods such as chi-square test and multiple logistic regression analysis. Results: The incidence rate of injury that lasted for two weeks was 4.7 per 1,000 persons. On the multiple logistic regression, the children and adolescents (OR=3.80, 95%CI=1.63-8.84) had higher rates of injuries than the adults, and the middle and high school (OR=0.51, 95%CI=0.31-0.85) and college(OR=0.34, 95%CI=0.17-0.68) students had lower rates of injuries than the elementary school students. The unemployed (OR=0.39, 95%CI=0.20-0.73) and others (OR=0.38, 95%CI=0.21-0,70) had lower rates of injuries than the blue collar workers. The major causes of injuries were found to be falling and slipping, and the most prevalent place of occurrence was near or at home. Conclusions: A prevention program needs to be developed and continuous education must be offered to the children, adolescents and blue collar workers.

Objectives: The aim of this study is to measure health literacy levels and to identify health literacy related factors in vulnerable elders. Methods: The research design for this study was a descriptive survey design using convenience samples. Data collection was done by interviewing questionnaire with 200 elders from welfare centers in the cities. Data were analyzed by using percentage, Chi-square and multiple logistic regression with the IBM SPSS Statistics Ver. 24.0. Results: The results of this study are as follows: Vulnerable elders' sources of health information levels were very low, especially internet. In multiple logistic regression analysis, monthly income, sources of health information were significant accounted for OR 2.201, p<.05, OR 2.989, p< .01 health literacy. Conclusion: These results suggest that interventions for improving health literacy are necessary to enhance elders' finding of health information. Also, these results could be used in developing health literacy programs by internet.

Purpose : Obesity indices are major predictive markers for coronary artery stenosis, but there are few studies about the relationship between obesity indices and coronary artery stenosis in the Korean population. Therefore, we analyzed the association between obesity indices and coronary artery stenosis among health-screen examinees. Methods : This study included 99 males and females who visited a health-examination center. The obesity indices included body mass index (BMI), waist circumference (WC), visceral adipose tissue (VAT), visceral adipose tissue/subcutaneous adipose tissue ratio (V/S ratio). All subjects had their degree of coronary artery stenosis measured using coronary computed tomography angiography (CCTA). A multiple logistic regression test was conducted to analyze the association between obesity indices and coronary artery stenosis. Results : This study was taken by multiple logistic regression test adjusted by age, sex, smoking status, frequency of alcohol drinking/week and frequency of exercise/week. The adjusted odds ratio for the presence of coronary artery stenosis for subjects with abdominal obesity (abdominal obesity defined as a waist circumference ≥ 90 cm in males; ≥ 85 cm in females) was 6.263 (95 % confidence interval (CI) 1.974-19.869), for subjects with visceral obesity by visceral adipose tissue (visceral obesity defined as a visceral adipose tissue ≥ 100) was 11.430 (95 % CI 3.044-42.928). Conclusion : In this study of adults, WC and VAT were independent predictors of coronary artery stenosis. These results suggest that WC and VAT may be useful markers of coronary artery stenosis.

Purpose: This research was conducted to study whether the specific location of pelvic-bone fractures could increase the risk for injury to the urinary bladder, urethra, or lower gastrointestinal tract. Methods: We retrospectively reviewed the data of 234 patients with pelvic-bone fractures who visited the emergency department of Kyungpook National University Hospital from January 2004 to December 2006. The location of the pelvic-bone fracture was divided into 8 parts. The association of fracture location with injury to the urinary bladder, urethra, or lower gastrointestinal tract was analyzed with Fisher' s-exact test and multiple logistic regression. Results: Nineteen(19) patients had urinary bladder injury, 8 had urethral injury, and 9 had lower gastrointestinal tract injury. The following fracture locations were found to be significant; urinary bladder: sacroiliac (SI) joint (p<0.001), symphysis pubis (p=0.011), and sacrum (p=0.005); urethra: SI joint (p=0.020); lower gastrointestinal tract: symphysis pubis (p=0.028). After the multiple logistic regression analysis, the primary and the independent predictors for each of the injuries were as follows; urinary bladder: sacroiliac joint (p=0.000, odds ratio [OR]=10.469); lower gastrointestinal tract: symphysis pubis (p=0.037, OR=7.009). Conclusion: Consideration of further workup for injuries to the lower gastrointestinal and urinary tract is needed for some locations of pelvic-bone fractures because certain pelvic-bone fracture locations, especially the sacroiliac joint and the symphysis pubis, are associated with increased risk for injury to the lower gastrointestinal and urinary tracts.

Objectives: This study was conducted to investigate how willingness to have an additional childbirth was related to mother's general characteristics and various reasons for avoiding an additional childbirth. Methods: By using organized questionnaire, we had face-to-face interviews with 722 mothers who had 12 to 36 months child in a urban-rural area of Chungcheongnam-do from 14 February to 19 February in 2005. Questionnaires included general characteristics composed of age, monthly income, number of children, major carers and mother's job status, and 6 reasons for avoiding an additional childbirth. We performed chi-square test and multiple logistic regression analysis. Results: Of 722 mothers, 66.5% had no willingness to have an additional childbirth. In the multiple logistic regression analysis, old age of mother(95% CI of OR: 1.084-1.190), two or more children(95% CI of OR: 6.97-15.602) and weak norm about need for a child(95% CI of OR: 1.633-29.352) were independent related factors with willingness to have an additional childbirth. Conclusions: In our study, 2/3 women who already had children were appeared to have no willingness to have additional childbirth. Policies about family planning and controlling birth rate should be focused on eliminating barrier to additional childbirths.

Background: The number of cancer survivors is increasing globally and recently, higher rates of comorbidities in cancer survivors have been reported. However, no studies have investigated whether cancer survivors have a higher risk of chronic kidney disease (CKD). Accordingly, our study evaluated the association between cancer survivors and the risk of CKD using the 2010-2012 Korean National Health and Nutrition Examination Survey. Materials and Methods: A total of 11,407 participants aged 40 years and over were categorized into two groups according to cancer experience. Multiple variables were compared and the odds ratios (ORs) for CKD prevalence were calculated using a weighted logistic regression analysis between the two groups. Results: Cancer survivors were older than were those in the non-cancer group, on average, the percentages of glomerular filtration rate(GFR) lower than $60mL/min/1.73m^2$, proteinuria, and CKD were significantly higher in cancer survivors when compared to controls. Weighted logistic regression analyses demonstrated that cancer survivors had a higher risk for CKD after adjusting for multiple variables (OR (95% confidence interval), 2.88 (1.48-5.59)). Conclusions: Our study demonstrated a possible association between CKD and cancer survival in Korean adults. Identifying and correcting risk factors for cancer survivors would positively affect prevention of CKD and result in a better cancer prognosis.

Objectives : This is a retrospective statistical analysis of the demographic and therapeutic characteristics influencing the continued improvement of symptoms in patients treated in 2014 for herniated lumbar discs at a Korean medicine hospital; thereby, providing clinical data to further improve medical services of Korean medicine. Methods : We investigated the demographic and therapeutic variables of all patients who were diagnosed with a herniated lumbar intervertebral disc and were hospitalized for more than 1 night at Dunsan Korean medicine hospital from January 1, 2014, to December 31, 2014. IBM SPSS 21.0 was used to conduct a logistic multiple regression analysis and a covariance analysis (ANCOVA) of the demographic and therapeutic variables collected from the electronic medical records and telephone surveys. Results : 1. A longer duration of hospitalization was significantly better for the maintenance of pain relief or a decrease in the pain after discharge. 2. Younger patients were significantly less likely to be treated with a Western medical treatment after discharge. 3. Most of the demographic and therapeutic variables were not statistically significant in regards to treatment for lower back pain since discharge. Conclusion : Some of the demographic and therapeutic variables had a positive effect on the prognosis at one year or greater in patients who received integrative Korean medical treatment for lumbar disc herniation. Continued and systematic research will be needed.

Purpose: This prospective cohort study was done to investigate recall bias to antepartum variables measured at postpartum periods and predictors of postpartum depression. Methods: Participants were 215 women who answered a self-administered questionnaire which included demographics, Postpartum Depression Predictors Inventory-Revised and Korean version of Edinburgh Postpartum Depression Scale at antepartum 36-40 weeks and postpartum 2 weeks and 6 weeks. Data were analyzed using kappa, and hierarchical multiple logistic regression. Results: Agreement between antepartum variables at both antepartum and two postpartum periods was relatively high (${\kappa}$=.55- .95). Postpartum depression rates were 36.3% and 36.7% at two follow-up points. In hierarchical multiple logistic regression analysis, prenatal depression (OR=4.32, 95% CI: 1.41-13.19; OR=5.19, 95% CI: 1.41-19.08), social support (OR=1.40, 95% CI: 1.18-1.66; OR=1.27, 95% CI: 1.06-1.53) and maternity blues (OR=4.75, 95% CI: 1.89-11.98; OR=4.22, 95% CI: 1.60-11.12) were commonly associated with postpartum depression at two follow-up points. Child care stress (OR=1.85, 95% CI: 1.01-3.37) was only associated with postpartum depression at 2 weeks postpartum and pregnancy intendedness (OR=1.57, 95% CI: 1.09-2.27) was only associated with postpartum depression at 6 weeks postpartum. Conclusions: The results indicate a need to apply nursing interventions such as prenatal education and counseling with families from antenatal period.
