Recently, a research on obtaining a vital signal using a Doppler radar has been developed and is used as a technology applied to patients in bed. However, in the case of the measured pulse, the respiration signal is generated as noise, resulting in a problem of lowering accuracy. In this paper, we propose a bio-signal measurement algorithm based on the sampling point to improve the accuracy of the signal for measuring the pulse rate when measuring bio-signals using a Doppler radar. The proposed algorithm improves the accuracy of the measured bio-signal by removing noise generated when measuring biosignals based on two sampling points. Compared with actual medical equipment and existing bio-signal algorithms, it is more than 90% similar to medical equipment. In addition, it was confirmed that severe amplitude change was minimized compared to the existing algorithm.

The profitability of a hospital refers to business administration results achieved through its medical care and other management activities during applicable fiscal year. This study focused on operating margin as a measurement index of hospital profitability, which is a genuine medical return obtained by subtracting medical expenses from medical profits achieved during business administration of hospital. Based on the index, this study could deduce certain factors on hospital profitability in terms of various indices affecting profitability. And based on those factors, this study sought to provide more useful reference materials which allow us to devise possible ways to improve hospital profitability. As a result, it was found that public hospitals attained lower profitability than private ones. To analyze profitability depending on each index, this study divided hospitals broadly into deficit group and surplus group. As a result, it was found that there were significant differences in hospital profitability between two groups depending upon relevant indices such as labor cost ratio, maintenance expense ratio, number of operations per medical specialist and medical instrument turnover. According to analysis on potential effects of relevant indices upon profitability, it was found that each index had its explanatory power ranging from 25% to 74.5% depending on given model.

Purpose: This study aimed to investigate the current statistics of professional medical support staffs(PMSSs) working in general hospitals with less than 500 beds. Methods: This study was conducted on 35 general hospitals with less than 500 beds from September 11th to October 27th, 2017. Results: Four hundred fifty one PMSSs were currently providing medical support. The number of clinical nurse experts was the highest among the roles, followed by Physician Assistants(PA) and Advanced Practice Nurses. The mean job satisfaction score was 3.07 out of 5. In the case of PA group, most of the delegated prescriptions were performed, however the delegated roles were not much documented in written format. The paucity of documentation requires a development of a committee for PMSSs, including a development of selection criteria and a scope of practice in each institution. Conclusion: The results of this study suggested the composition of a committee for PMSSs in the medical institutions and renaming the specified titles of PMSSs.

This study was conducted to examine the mediating effect of innovative behavior in the relationship between nurse manager's leadership and nurses' future use of evidence-based practice. Participants were 183 nurses working at general hospitals with over 500 beds in Korea. Nurse manager's transformational leadership was positively correlated with innovative behavior and nurses' future use of evidence-based practice. Innovative behavior showed partial mediating effects in the relationship between nurse manager's leadership and nurses' future use of evidence-based practice. These findings suggest that in order to enhance nurses' future use of evidence-based practice, the educational strategies to promote nurses' innovative behavior should be developed and provided in nursing field.

The purpose of this study was to evaluate the relative weight of infectious disease vulnerability indicators that affect the occurrence and spread of infectious diseases in local communities. For this, the infectious disease vulnerability indicators were classified as facilities vulnerable to spread, vulnerable groups of infections, social vulnerable conditions, and response capabilities based on literature and case review, and the relative weights among indicators were determined using Analytic Hierarchy Process(AHP) by 22 experts. As a result of the analysis, the weight of each sector was found to be the highest in the facilities vulnerable to spread, and the overall weight was highest in the following order: sickbed securing rate(1st), density of religious facilities(2nd), medical personnel rate(3rd), elderly person ratio(4th), and entertainment establishment density(5th). These results can be used to prepare the supporting data necessary for the establishment of infectious disease response policies of local governments.

The use of smart phones has had a great impact on the mobile internet business. It shows a lot of growth in the healthcare sector not only commerce, advertising, billing, games, video content, media, amd O2O business. The United States has eased the regulations for healthcare apps smart phone devices in 2015, and China has established a five-year road map to solve shortage of doctors and hospital beds by utilizing mobile devices such as wearable in the same year. The application of wearable devices in the medical field is gradually increasing in Korea too, but there is a security problem as leading challenge. Security incidents in non-ICT sectors such as financial, medical, etc. have increased by using ICT each year. Personal information leakage is also increasing in field likely occurring the potential secondary damages such as financial fraud, illegal promotions, insurance and pharmaceutical companies abuse. In this study, we analyze malwares as the mobile threats, the five risks of mobile smart phone, mobile use cases and the mobile threat countermeasures for healthcare.

This study was examined to confirm the effect of emotional labor and social support on Job embeddedness in clinical nurses. The subjects were working in general hospitals over 300 beds in Gwangju area. The 197 data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation analysis, and hierarchical regression analysis. Deep acting(r=.290, p<.01) of emotional labor and supervisor support(r=.389, p<.01) and peer support (r=.160, p<.05) of social support were reported positively correlated with job embeddedness. Deep acting(${\beta}=.236$, p<.001) of emotional labor and supervisor support(${\beta}=.319$, p<.001) of social support were reported to have effect on job embeddedness. These findings suggest that in order to promote job embeddedness of clinical nurses, the strategies to improve deep acting of emotional labor and supervisor support of social support should be provided in clinical nursing field.

Purpose: As the medical laboratories in general hospitals have made an efforts on quality management and employee health, they recognized the need of design guideline for clinical laboratory. As laboratories are prohibited to patients, their environments are becoming more congested and deteriorated as time goes by. So, this study investigates the current status of facility and equipment of laboratory medicine focusing on less than three hundred patient bed hospitals, and searches the improving matters. Methods: Questionnaires to technologist captains and field surveys to medical laboratories in korean hospitals have been conducted for the data collection. 18 answers have been analysed statistically by MS Excel program. Results: The result of this study can be summarized into followings. Clinical laboratory functions are all hematology, clinical chemistry, immunology, transfusion and urine microscopy, and except for three including microbiology for infection and bio safety level. Average man power of lab are 12.3 man including lab director and captain. Patient bed number, space area and total specimen numbers are not correlated with each other, but specimen numbers and employee number are correlated with. Work space distances are usually good, but exit distances are not adequate for escape owing to obstacles. Specimen delivery system by courier, test method by automatic analyzer, access floor for exposed plumbing and electricities are more practical. Open lab layed out in the center and lab support layed peripheral in space diagram. Lab space configuration by SD method showed that lab support area and employee support area are dissatisfied. Implications: Specialized hospital and yearly total specimen numbers are related to the space area and organization for laboratory planning and design.

This work aims to use the analytic hierarchy process (AHP) tool to develop the model of industrial competitiveness in the nursing homes of eleven provinces in east China. The original data is from China Civil Affairs Statistical Yearbook 2020. The results show that Jiangsu province has the highest competitiveness in the elderly care industry among the eleven provinces in east China, and Hainan province has the lowest competitiveness. The competitiveness of the elderly care industry varies among the eleven provinces in east China. The ratios of beds to medical staff, the ratio of nursing homes, per capital fixed assets in nursing homes, and the number of unable self-care elderly are the four main influential factors across the competitiveness of the elderly care industry and indicates that the nursing homes competitiveness is affected by multiple factors from multiple levels. A differentiated strategy should be taken according to the circumstances in different provinces to rationally develop the elderly care industry, improving efficiency, the level, and quality of services in the nursing homes.
