Previously, we reported the concept of a cloud-based telemedicine platform for patients with intracerebral hemorrhage (ICH) at local emergency rooms in rural and medically underserved areas in Gangwon state by combining artificial intelligence and remote consultation with a neurosurgeon. Developing a telemedicine ICH treatment protocol exclusively for doctors with less ICH expertise working in emergency rooms should be part of establishing this system. Difficulties arise in providing appropriate early treatment for ICH in rural and underserved areas before the patient is transferred to a nearby hub hospital with stroke specialists. This has been an unmet medical need for decades. The available reporting ICH guidelines are realistically applicable in university hospitals with a well-equipped infrastructure. However, it is very difficult for doctors inexperienced with ICH treatment to appropriately select and deliver ICH treatment based on the guidelines. To address these issues, we developed an ICH telemedicine protocol. Neurosurgeons from four university hospitals in Gangwon state first wrote the guidelines, and professors with extensive ICH expertise across the country revised them. Guidelines and recommendations for ICH management were described as simply as possible to allow more doctors to use them easily. We hope that our effort in developing the telemedicine protocols will ultimately improve the quality of ICH treatment in local emergency rooms in rural and underserved areas in Gangwon state.

The purpose of this study is to design and implement a maritime telemedicine system to provide the best medical service for patients who rescue and happens in sailing ship. For this purpose, INMARSAT and MVAST, which are necessary communication channels for maritime telemedicine, were examined and diversity in maritime communication path was suggested. It was implemented to enable maritime telemedicine by linking smart devices and medical devices for physical examination. The marine telemedicine system adopts the HTTP communication protocol to configure the web server and process the client request. The patient's chart information was entered using an application for AndroidPad and the patient was diagnosed using Bluetooth electronic stethoscope for diagnosis. This system enables appropriate medical treatment to emergency patients at maritime, which ultimately can improve medical services. It is expected to be a more effective medical support system through linkage with various medical equipment.

The purpose of this study was to examine the scope of work of femergency medical technician who can directly affect the resuscitation of emergency patients at the pre-hospital stage. As a result of the main study, the overall level of the subjects' work scope expansion averaged 3.34points(out of 5points), and among the items, 'The scope of work of emergency medical personnel should be expanded by revising the Act on emergency medical cars' was the highest. As for the difference in the expansion of the scope of work of paramedics by position, 'The current telemedicine guidance system is inconvenient to use' was the highest for emergency medical technicians, and there was a statistically significant difference(p<.01). Based on this study, it is believed that repeated studies are needed to establish and generalize the scope of work of paramedics.

Many attempts have been made for the health and lives of patients at a remote site. but little attention has been given to emergency system using wireless or other intelligent networks. In this paper, shown is a remote emergency system which can be used in an ambulance. It possibly gives a great help to the patients who may lose their lives, in other words, gives pre-hospital cure to them being sent to the hospital. Doctors or specialists are able to give a quick help which may give a new life to patients. This system deal with very important patient's data-ECG, SpO$_2$, blood pressure, biomedical signal data etc. - as other emergency system. A good performance better than other system is many but shortly spoken as follows. First, this system is user friendly system activated in windows 2000 environment. Second, MPEG4 and ECG data sent to the other station for specilists can give a pre-hospital cure to patients in advance. Third, there exist effective algorithms to operate this system. Fourth, this system has been made with software mostly, so this system can be easily embedded in IBM compatible computer. In addition to this performance, for the better and reliable system, various tests were proceeded and recursively tested. Tests were made in EV-DO wireless network and Local Area Network. This mobile-fixed remote emergency system using wireless network like EV-DO network will give a great usage to needed area.

Advanced countries such as the USA and Japan are eagerly seeking ways to improve health and welfare of the elderly. One of the services is home health care service using the telephone. Various types of services using the telephone have been developed, improved and are being utilized ranging from the basic consulting to emergency response systems in the area of health care for the elderly. A demonstration project was launched to study the feasibility of a consulting system and telemedicine for the elderly using the public phone system in Korea. For this project, a gathering site for the elderly was selected and those who visited this place were interviewed to find out what kinds of services they wanted and what kind of system they needed to provide the required services. Based on the users' requests and the surrounding environment, a telephone consulting facility was established at the Research Institute of Nursing Science at Seoul National University and consulting personnel was recruited, trained and posted at the center. An Application program for home health care nurses to use when they visited the patients at their homes was developed. This system operates on a notebook Computer and allows nurses to communicate with a doctor at a local hospital through a modem and telecommunication line. These systems were implemented for three months and problems which developed during operation of the systems were identified and progressively modified. Through system evaluation, it was found that a consulting system using phone service will be an invaluable system for the welfare of the elderly in the future. But in order to meet the elderly's need, more services than mere consultation are needed. That is, communication with physicians and hospitals are needed. Thus, when there is any need for physicians' attention, physicians or hospitals should be contacted directly. Similarly for telemedicine, when the home health care nurse visits elderly patients she can assess the patient's problem and provide nursing care, access a physician or hospital to refer her patient to or consult directly using the telecommunication the system. The above mentioned system is a basic form of futuristic telemedicine for the elderly and those who have chronic disease problems. This kind of system will be of great value when it is used on the national information super-highways in the future. In order to get to that stage, of course, this project needs great improvement in the technical, academic, and legal aspects.

Purpose: Critically ill patients are frequently transferred from one point of care to a hospital that can provide a higher level of care. To achieve optimal treatment within the targeted window of time necessary for time-sensitive cases like major trauma, rapid transportation and decision making are essential. Transferred patients have often undergone radiologic imaging at the referring hospital. Examining these outside images is paramount. Therefore, this study was conducted to estimate the upload time of outside images. Methods: This retrospective study was conducted from January to April 2020. Patients transferred from other hospitals with digitally recorded CDs or DVDs of radiologic or diagnostic images were included. When the patients were registered at the emergency department reception desk, the digital images were transmitted to our picture archiving and communication system using transmission software. The time of upload and the numbers of digital images were recorded. The time interval from patient registration to the time of upload was calculated. Results: The median number of images was 688 in the trauma team activation (TTA) group (688 in the TTA group, 281 in the non-TTA trauma group, and 176 in the nontrauma group, respectively; P<0.001). The median upload time was 10 minutes. The longest upload time was 169 minutes. The upload time was more than 20 minutes in 12 cases (19.4%). Conclusions: Patients with major trauma bring more images than patients with other diseases. Unexpected delays (>20 minutes) were noted in approximately 20% of cases. It is necessary to minimize this time.

Objective : Due to the implementation of vaccinations and the development of therapeutic agents, the coronavirus disease 2019 (COVID-19) pandemic that started at the end of 2019 has entered a new phase. As a result, neurosurgeons should reconsider the way they treat their patients. As the COVID-19 situation prolongs, the change in neurosurgical emergency patients according to the number of confirmed cases is no longer clear. Outpatient treatment by telephone was permitted according to government policy. In addition, visits to caregivers in the intensive care unit were limited. Methods : The electronic medical records of patients who had been treated over the phone for a month (during April 2020, while the hospital was closing) were reviewed. Meanwhile, according to the limited visits to the intensive care unit, a video meeting was held with the caregivers. After the video meeting, satisfaction was evaluated using a questionnaire. Results : During April 2020, 1021 patients received non-face-to-face care over the telephone. Among the patients, no critical medical problem occurred due to non-face-to-face care. From July 2021 to December 2021, 321 patients were admitted to the neurosurgical intensive care unit and 107 patients (33.3%) including their caregivers agreed to video visits. Twice a week, advance notice was given that access would be made through a mobile device and the nurse explained to caregivers how to use the mobile device. The time for the video meeting was approximately 20 minutes per patient. Based on the questionnaire, 81 respondents (75.7%) answered that they agreed, and 26 respondents (24.3%) answered that they strongly agreed that was easy to communicate through video meetings. Fifty-two (48.6%) agreed and 55 (51.4%) strongly agreed that they were easy to understand the doctor's explanation. For overall satisfaction with this video meeting, three respondents (2.8%) gave 4/5 points and 95 respondents (88.8%) gave 5/5 points, and nine (8.4%) gave 3/5 points. Their reason was that there was not enough time. Conclusion : In situations where patient visits are limited, video meetings through a mobile device can provide sufficient satisfaction to caregivers. Telemedicine will likely become common in the near future. Health care professionals should prepare and respond to these needs and changes. Therefore, establishing a system with institutional support is necessary.
