Healthcare services can be provided through a number of independent service platforms for measurement of vital signs, diagnosis and prevention of diseases, and Information and communication technology(ICT) such as internet and mobile are converged to provide health information to users at anytime and anywhere, and it is in the center of the IoT(Internet of things). Accordingly, in this paper, we designed IoT based urination management system and evaluate the performance. A low - power Zigbee network was constructed for the configuration of the urination management system. The implemented capacitive diaper sensor was operable for the duration of 2,000 hours. We also built a database server using Raspberry Pi, a tiny embedded device, and stored the collected data to verify the data through an Android-based mobile application. The proposed urination management system can be utilized not only for the older patients, but also for the infants.

Application of information system to hospital would bring innovative improvement on efficiency of business management and provide high quality services toward patients as well as the retrenchment of operating funds. PACS(Picture Archiving and Communication System) including X-ray film that manages the medical image information effectively, has drawn considerable attention to essential structural elements to the sophisticated information system for hospital. PACS system should be connected to the network after making a form of standard medical image file from different style of image information obtained from various medical instruments. In this paper, to solve this problem, we construct Mini-PACS that converts the form of Non-DICOM file to the form of standard file by designing the DICOM converter. This system is designed to be managed under Web environment. Comparing with the existed Mini-PACSs, consisting of the client and server module, our system is designed and implemented with integration of these functions in order to be strongly combine strongly between system.

Recently pathogenic E. coli is one of the main foodborne pathogens resulting in many patients in Korea. To understand the characteristics of pathogenic E. coli outbreaks in Korea, the epidemiological investigation reports of pathogenic E. coli outbreak in 2009 (41 reports) and in 2010 (27 reports) were collected in the web site of the Korea Centers for Disease Control and Prevention, reviewed and analysed in this study. The main places of the pathogenic E. coli outbreaks were food catering service area (64.8%) and restaurants (25.0%). The main type of the pathogens were EPEC (44.7%) and ETEC (34.2%). EAEC and EHEC was responsible for 10.5 and 9.2%, respectively. Eight of 68 outbreak cases were caused by more than 2 types of pathogenic E. coli which implicates the complicated contamination pathways of pathogenic E. coli. The incidence rate of pathogenic E. coli was $33.6{\pm}30.5%$ and the main symptoms were diarrhea, stomach ache, nausea, vomiting, and fever etc. The two identified food sources were identified as frozen hamburger pattie and squid-vegetable mixture. To improve the food source identification by epidemiological investigation, food poisoning notification to the agency should not be delayed, whole food items attributed the outbreak should be collected and detection method of the various pathogenic E. coli in food has to be improved. In conclusion, the characteristics between the EHEC outbreaks in the western countries and the EPEC or ETEC outbreaks in Korea needs to be distinguished to prepare food safety management plan. In addition, the development of the trace back system to find the contamination pathway with the improved detection method in food and systemic and cooperative support by the related agencies are necessary.

In recent years, medical procedures have become more complex, while financial pressures for shortened hospital stays and increased efficiency in patient care have increased. As a result, several shortcomings of present film-based systems for managing medical images have become apparent. Maintaining film space is labor intensive and consumes valuable space. Because only single copies of radiological examinations exist, they are prone to being lost or misplaced, thereby consuming additional valuable time and expense. In this paper, mini-PACS for image archiving, transmission, and viewing offers a solution to these problems. Proposed mini-PACS consists of mainly four parts such as web module, client-server module, internal module, acquisition module. In addition, mini-PACS system includes DICOM converter that non-DICOM file format converts standard file format. In client-server module case, proposed system is combined both SCU (service class user: client) part and SCP(service class provider: sewer)part therefore this system provides the high resolution image processing techniques based on windows platform. Because general PACS system is too expensive for medium and small hospitals to install and operate the full-PACS. Also, we constructed web module for database connection through the WWW.

Recently, the number of confirmed cases has increased again with the new variant of COVID-19. Quarantine is recommended, especially to prevent the rapidly increasing spread, as environmental controls, such as minimizing contact with others, can increase safety. In addition, there are often cases in which the patient's condition cannot be confirmed from the standpoint of a guardian, such as visitation being prohibited under certain conditions. At this time, the sensor data values of oxygen, carbon dioxide concentrations, temperature and humidity, and alcohol, which are medical gases used in hospitals, are collected remotely using ZigBee wireless communication technology. Design a system that can be stored and monitored in a database. We propose an environmental monitoring system, which is a visualization system designed to allow hospitals to check and feedback data on the managed environment, and to give reliability to parents.

This study evaluated the standardization of the outpatient management process in several regions of South Korea. The hospital workers in the administration department of the different medical institutions that are registered with the Korean Hospital Association were surveyed. These institutions can be standard hospitals or hospitals greater in size. A summary of the research results are as follows. There was no significant correlation in their registration procedures in relation to the institution's founder, number of sickbeds, number of staff employed in the administration department, and average number of outpatients per day. On the other hand, the prepayment of medical fees occurred more frequently when the number of sickbeds was larger. In addition, there was no large difference in their appointment procedures in relation to those features. Nevertheless, the prepayment of medical fees accounted for 11.8 % of the entire payment in institutions with less than five hundred beds, while fifty percent of the payment was made in advance in larger institutions with five hundred or more beds. From this research, there was only a small difference among the institutions' outpatient management, but a notable difference was observed in their electronic data processing systems and facilities. Therefore, more financial support should be generated for the implementation of a more integrated process. As a follow-up study, to provide patients with quality medical services, it will be necessary to apply the standardized procedure to an actual medical institution and analyze the expected effect.

This study aims to analyze physicians' online information search process to solve the clinical questions at the point of care. To achieve this purpose, ten university hospital-based physicians participated in-depth interviews and observation studies. Based on Wilson's problem solving process, this study analyzed the characteristics of each information search stage and efficiency of online searching. The results showed that participants tend to relatively immediately formulate their clinical questions. However, basic searching strategies were only used and a few preferred information sources were chosen. However, average satisfaction degree of online searching appeared high with 5.7 (7 Likert-scale) and problem-solving index increased after searching. As physicians are likely to use well organized and evidenced-based credible information easily, it implies the needs for an integrated search system within the electronic medical record (EMR). In addition, as other online resources' awareness is lower comparing Google and PubMed, active promotions and training of other resources are needed.

To improve the quality of life, wireless ad-hoc network technologies are considered as one of the key research areas in computer science and healthcare application industries. The ubiquitous healthcare systems also provide alerting mechanisms against ill conditions in real time. This minimizes the need for care-givers and helps the chronically ill and elderly to survive. For the application of the system, supporting the efficient and proper network system is essential. So in this paper, I suggest some hospital network environments including patient mobile nodes continuously sending brainwaves to the server of the hospital area. Finally, the network systems are simulated by OPnet simulator and evaluate the performance among various mobility of the mobile nodes and topologies of the network for the efficient system.

This is a convergence study to provide an effective way of managing nurses' job stress by improving nurse satisfaction through an integrated identification of the effect satisfaction level on job stress for nurses using an electronic medical record(EMR) system. The data were collected from August 1 to September 1, 2014. The participants were 377 nurses from C university hospital of G metropolitan city were analyzed using SPSS 21.0. The result shows that job stress decreases as nurses' satisfaction level of using the EMR system increases. Thus, a practical job stress mediation program should be developed to continuously enhance nurses' satisfaction with the EMR system, which is expected to shorten the nursing record writing time and improve the quality of nursing service for patients. Furthermore, to improve the satisfaction with the EMR, appropriate management, such as continuous nursing education on the EMR system, will be needed.
