The purpose of this study is to evaluate the convergence effectiveness of treadmill training in patients with chronic stroke through a meta-analysis. After searching the literature based on the patients, intervention, comparison, outcome criteria, and study desigan, a total of 22 studies related to "stroke" and "treadmill" were eligible for inclusion. Effect size was calculated using the comprehensive meta-analysis program for the meta-analysis. Based on the forest plot results, the overall effect size of treadmill training was 0.661 (95% confidence interval: 0.456-0.865), which was statistically significant with a medium effect size (p < 0.05). The effects of treadmill training on patients with stroke were separated by dependent variables of interest-plantar pressure (1.147), lower limb muscle function (0.875), and balance (0.664). The effect sizes were evaluated for the subdomains of timed up and go test (0.553), Berg Balance Scale (0.760), and static balance index (0.654) for balance. Therefore, treadmill training can be expected to have a positive impact on improving the quality of life of patients with chronic stroke. This meta-analysis of treadmill training may the lead to an industry paradigm shift toward healthcare convergence of information, communication, and medical technology.

This descriptive investigation aims to identify a relationship between QOL, depression, and anxiety in hemodialysis patients. I conducted this research on 130 subjects aged 19 or above who have received dialysis for at least one month in the hemodialysis unit at N hospital in the city of S. However, it came to 112 as I took out those who either quit, died, or filled out a questionnaire in the incorrect manner. In regards to average points of QOL on a 100-point scale, it is 57.77, demonstrating quite low QOL. Concerning average points of depression and anxiety, it is 12.25 and 10.52, respectively, showing quite a high figure. With regard to a correlation, there is a significant correlation between the three factors in hemodialysis patients: there is a negative correlation between QOL and depression (r=-.782, p<.001); a negative correlation between QOL and anxiety (r=-.719, p<.001); and a positive correlation between depression and anxiety (r=.873, p<.001). The outcome of multiple regression analysis on factors affecting QOL shows that depression is the element influencing QOL (β=-.585). Therefore, this study is significant in providing basic data for establishing intervention strategies aiming to reduce levels of depression which has the strongest impact on QOL in the patients and for developing a nursing intervention program intending to improve their QOL.

Purpose: This study aimed to investigate the performance of patient engagement nursing services perceived by nurses and necessity in Korea. Methods: This study was a descriptive research. A total of 205 nurses participated in the study. The Smart Patient Engagement Assessment Checklist was developed by the investigators to assess patient engagement nursing services performance and necessity. The data were collected using online survey. Descriptive analysis and $x^2$ analysis were performed using SPSS 25.0 program. Results: The mean age of participants was $36.6{\pm}8.5years$ and the mean working experience was $12.92{\pm}9.23years$. Seventy eight percent of participants reported that patients and family participated in care as advisors through customer's suggestion or patient satisfaction assessment. The rate of patients' and family's engagement in care as advisors was significantly higher in tertiary hospitals ($x^2=28.54$, p<.001). About 89% of participants communicated with patients and family to make clinical decisions with a multidisciplinary approach. The rate of communication for multidisciplinary decision making was significantly higher in tertiary hospitals ($x^2=6.30$, p=.012). With regards to nurses' bedside patient handoff, 22.0% of participants reported that they were performing bedside patient handoff, and there was no significant difference between type of hospitals. About discharge planning, 72.2% of participants reported utilizing discharge checklist. Conclusion: Currently, patient engagement nursing services are applied partially in Korea. It seems that care protocols to be applied for patient engagement nursing services are insufficient. Therefore, patient engagement care protocols need to be developed to improve patient's health outcome and safety.

The main purpose of this study is to figure out the spending tendency of elderly consumers for their grandchildren. To this end, a detailed survey was carried out for two months from October 1 to November 30, 2011. The respondents consist of 461 elderly consumers over 60s who have grandchildren in elementary grades. Among the gathered data, relevant information was sorted out, coded, and then turned into statistical figures through SPSS 18.0 program. The outcome of this research is explained in the following three respects. First of all, based upon factor and cluster analysis, the role of grandparents has been divided into three categories, which are a babysitter, a friend and a visitor. Depending on their role, the surveyed elderly have been split into three groups-'Friend Group', 'Formal Visitor Group', 'Attached Group'. Second, to give you an overview of the consumption trend of the three groups, this study has reviewed the expenditure items, spending amount and consumption patterns, and made a list of products and services they purchased for the past one year for their grandchildren. Third, given the probability of wealth transfer to the next generation, there is a compelling need to figure out the purchase pattern of financial products. The elderly have been categorized into those with bank deposits only and those with a mixture of bank deposits and other financial products (insurance, fund, stocks, gold, dollar etc.).

To investigate the effect of high-intensity interval training (HIIT) on the outcomes of cardiac rehabilitation(CR) in elderly and younger patients with myocardial infarction(MI). Of the MI patients who received hospital-based CR from 2015 to 2017, we retrospectively reviewed the medical records of the patients who continued follow-up through the outpatient clinic. A total of 39 patients (20 elderly patients (${\geq}60year$($64.1{\pm}3.6$)) and 19 younger patients (< 60 year($55.6{\pm}2.3$)) was included in this study. The HIIT program was composed of 10 minutes of warm-up, 30 minutes of interval aerobic exercise, and 10 minutes of cool down. The aerobic exercise based on their initial exercise tolerance test outcome consisted of 3-minute usual intensity phase (60-70% of heart rate/VO2 reserve) and 4-minute of high-intensity phase (70-90% of heart rate/VO2 reserve). Exercise capacity was measured by exercise tests before and after hospital- based CR. Before CR, elderly group had a significantly lower exercise capacity in Exercise time, peak VO2, METs, Anaerobic threshold, VEmax, 02pulse than younger group. Both group showed similar improvement of cardiopulmonary exercise capacity after CR. And HIIT is safe and effective in elderly patients. It is considered necessary to further expansion for the participation of high intensity interval training in elderly patients.

This paper is a study to analyze when ISV(independent software company) has more active participation in the platform ecosystem. According to previous studies, companies are active in technological innovation when they can appropriate the outcome of innovation and when they have complementary assets (marketing, manufacturing capabilities, etc.) that can convert the innovation into value. The effect of these two conditions to join platform ecosystem is investigated. The duplication between the ISV's product portfolio and platform service is also included as an independent variable. The two sample groups are composed of independent SW companies that signed a partner agreement with platform companies and non-participating companies in the platform. As a result of empirical study, it is found that the patent rights do not affect participation in the platform. The ISVs might have believed that the benefits from cooperation with platform companies are greater than the risks of exposure to innovative technologies and unique Biz models. On the other hand, downstream's capability and the duplication of product portfolio affect participation in the platform. If ISVs have the downstream capability to transform cooperation into value creation, ISVs are actively participating in the platform. In addition, cooperation is active when the product portfolio is complementary to platform service rather than competition. This study is the empirical study of open innovation between Korean independent software companies and digital platform companies. There are similar prior studies abroad, but there are no similar studies in Korea. It is meaningful in that the determinants of platform ecosystem participation were investigated through empirical analysis by composing a sample group of companies participating in the platform ecosystem and companies not participating in the platform ecosystem.
