Background: Physical activity (PA) is ranked as a leading health indicator and the workplace is a key setting to promote PA. The purpose of this study was to examine how goal-setting and exercise self-efficacy (SE) during a health promotion program influenced PA level among Japanese workers. Methods: Using a cross-sectional study design, we surveyed 281 employees. The short version of the International Physical Activity Questionnaire was used to assess PA level. Exercise SE was assessed using a partially modified version of Oka's exercise SE scale. Personal goals were assessed as the total numbers of "yes" responses to five items regarding "details of personal goals to perform PA". A mediational model was used to examine whether exercise SE mediates between the number of personal goals and PA level. Results: The mean age of the participants was 46.3 years, 76.2% were men, and the most common occupational category was software engineer (30.6%). The average PA level per week exceeded the recommended level in 127 participants (45.2%). One hundred and eighty-four participants (65.5%) set some form of concrete personal goal to perform PA. The relationship between the number of personal goals and PA level was mediated by exercise SE. Conclusion: Our study showed that exercise SE mediates goal-setting and increases PA. The results suggest that the components of PA promotion programs should be tailored to enhance participants' confidence in performing PA.

Objective : The purpose of this study is to evaluate the correlation of the ICAM-l levels in serum and CSF with cerebral vasospasm in early aneurysmal subarachnoid hemorrhage [SAH] patients. Methods : A prospective analysis was performed in thirty consecutive patients who underwent early surgery for intracranial aneurysmal SAH. The serum and CSF were obtained daily through the indwelling arterial lines and intraoperative ventriculostomy, or cisternal drain for 4 consecutive days after surgery. The ICAM-1 levels in serum and CSF samples were measured via quantitative enzyme-linked immunosorbent assay. Results : The mean concentration of serum in aneurysmal SAH patients was 207.89ng/ml compared with 132.25ng/ml in controls. The mean concentration of CSF in aneurysmal SAH patients was 76.39ng/ml compared with 3.96ng/ml in controls. There were no significant differences between serum and CSF ICAM-1 level with regards to clinical characteristics in patients with aneurysmal SAH [P>0.05]. However, CSF ICAM-1 levels increased significantly in patients with vasospasm compared with those without vasospasm [P<0.05]. Conclusion : The major result of this study shows that ICAM-1 is increased in CSF after early aneurysmal SAH and that this increase in ICAM-1 has correlation with cerebral vasospasm. Further study is needed to determine whether ICAM-1 levels may be indicator in the pathogenesis of important events leading to cerebral vasospasm.

The study aims to examine the current status and differences in the burden of disease in Korea during 2008-2018. We calculated the burden of disease for Koreans from 2008 to 2018 using an incidence-based approach. Disability adjusted life years (DALYs) were expressed in units per 100 000 population by adding years of life lost (YLLs) and years lived with disability (YLDs). DALY calculation results were presented by gender, age group, disease, region, and income level. To explore differences in DALYs by region and income level, we used administrative district and insurance premium information from the National Health Insurance Service claims data. The burden of disease among Koreans showed an increasing trend from 2008 to 2018. By 2017, the burden of disease among men was higher than that among women. Diabetes mellitus, low back pain, and chronic lower respiratory disease were ranked high in the burden of disease; the sum of DALY rates for these diseases accounted for 18.4% of the total burden of disease among Koreans in 2018. The top leading causes associated with a high burden of disease differed slightly according to gender, age group, and income level. In this study, we measured the health status of Koreans and differences in the population health level according to gender, age group, region, and income level. This data can be used as an indicator of health equity, and the results derived from this study can be used to guide community-centered (or customized) health promotion policies and projects, and for setting national health policy goals.

Wall obstruction is the main factor leading to the non-line of sight (NLoS) error of indoor localization based on received signal strength indicator (RSSI). Modeling and correcting the path loss of the signals through the wall will improve the accuracy of RSSI localization. Based on electromagnetic wave propagation theory, the reflection and transmission process of wireless signals propagation through the wall is analyzed. The path loss of signals through wall is deduced based on power loss and RSSI definition, and the theoretical model of path loss of signals through wall is proposed. In view of electromagnetic characteristic parameters of the theoretical model usually cannot be accurately obtained, the statistical model of NLoS error caused by the signals through the wall is presented based on the log-distance path loss model to solve the parameters. Combining the statistical model and theoretical model, a hybrid model of path loss of signals through wall is proposed. Based on the empirical values of electromagnetic characteristic parameters of the concrete wall, the effect of each electromagnetic characteristic parameters on path loss is analyzed, and the theoretical model of regional path loss of signals through the wall is established. The statistical model and hybrid model of regional path loss of signals through wall are established by RSSI observation experiments, respectively. The hybrid model can solve the problem of path loss when the material of wall is unknown. The results show that the hybrid model can better express the actual trend of the regional path loss and maintain the pass loss continuity of adjacent areas. The validity of the hybrid model is verified by inverse computation of the RSSI of the extended region, and the calculated RSSI is basically consistent with the measured RSSI. The hybrid model can be used to forecast regional path loss of signals through the wall.

Purpose: The purpose of this survey was to identify a set of performance indicators for Korean APNs (Advanced Practice Nurses). Methods: A convenience sample of 78 APNs working in 2 leading hospitals in south Korea participated in the three-round Delphi survey. In the first round, subjects were asked to propose performance indicators to evaluate the effectiveness of their practice. They rated the relevancy of each indicator during the second round. In the final round of survey, subjects rated the relevancy of indicators again in the light of second round's overall results and they also were asked to check on current and future use of indicators. Results: After 5 months of three-round Delphi survey, 60 performance indicators were identified. In regard to relevancy, the 10 highly ranked indicators were patient satisfaction, self-care ability, expertise of service, family satisfaction, nurse satisfaction, satisfaction in nursing education, advanced nursing service count, education for patient/ family, education for nurse, and compliance. Advanced nursing service count, education for patient/ family, and education for nurse are currently used as indicators by more than 70% of respondents. Conclusion: Additional research is needed to identify subsets of performance indicators for specialized areas and to determine the validity and sensitivity of indicators.
