Purpose: This study was conducted to investigate how nurses who take care of terminal patients perceive fluid therapy and how this therapy is currently being used in hospitals. Methods: This survey included 200 nurses, 87 of whom were working in the oncology units of 3 university hospitals in Seoul, Korea, and 113 were working in 18 hospice centers. The data for this study were collected by means of structured questionnaires and analyzed by using the Statistical Analysis System software. The differences in perception towards fluid therapy between nurses working in oncology units and those working in hospice centers were examined using the $x^2$ test and analysis of covariance. Results: Fluid therapy was perceived more negatively by the nurses from hospice centers than by those from oncology units. Continuous subcutaneous infusion was used in hospice centers, but not in oncology units. In addition, the average amount of fluid infused daily differed significantly between the oncology units and hospice centers. Conclusion: Our results show that there were differences in the perception towards fluid therapy between nurses in different clinical settings. Nurses caring for terminal and palliative care patients should not simply provide or withhold fluid therapy, but rather develop a wider range of views on fluid therapy, focusing on effective alternative interventions.

In this study, after applying VR 360-degree video contents for intravenous infusion education, basic data on whether VR 360-degree video can be applied as educational content in the future is prepared by grasping the empathy and flow of nursing students in graduating grades. The VR 360 degree intravenous infusion educational content was developed in four-step process of planning, production, modification and completion. The design of this study was descriptive research, and the study period was from November 9 to November 22, 2019. The subjects of this study were 4th grade nursing students at a university, totaling 64 students. Nursing students watched VR 360 degree intravenous infusion educational content using HMD(head mounted display) under the safety management of the researcher. As a result of the study, the empathy of nursing students was 5.32±0.88 points and the flow was 6.02±0.84 points out of 7-point scale. The VR 360 degree intravenous infusion educational content developed in this study can be used as an educational medium in subjects and comparative departments, and it is necessary to specifically develop and verify teaching and learning methods in future studies.

Fluid is normally used so that certain drug can be administered to patients for certain period of time. There are many incidents in which patients or guardians need to call upon medical staff after estimating the time of fluid injection termination. In case fluid injection is terminated during certain period such as sleeping time or others, it may cause more fatigue for either patients or guardians. Also, it may lead to ineffective work as medical staff needs to monitor the quantity of fluid several times in order to check the time of fluid injection termination. Therefore, the purpose of this study is to propose LBS system combined of minimum equipment and active RFID to monitor the level of fluid in order to solve abovementioned problems. Also, it is expected to enhance the quality of medical service with service in which real-time monitoring of fluid quantity and patient location is conducted to provide accurate information to either patients, guardians, or medical staff(nurse) so that medical staff can locate and see patients at the time of fluid injection termination.

The nurses manually carry out the intravenous therapy for the patients. Using an Arduino, the fine flow controlling device was invented to provide an ongoing patient care. The medication is injected through a peristaltic pump, and the amount of the solution is controlled with a RGB color sensor. The power of the device is supplied through the batteries. An amount of the injection is measured with LIG strain sensor fabricated by 355nm UV pulsed laser. This system will provide a better medical service.

This paper describes the medical and IT convergence system using a smart phone and a heuristic method for the measurement of the dripping speed of the liquid in a drip chamber, which can estimate the remaining time using pattern recognition and difference image from video frame information based on Android technology. The video frames were first made using a smartphone camera and we calculated the difference image between the n image and the (n-1) image and then changed into binary images using the threshold value. At this point, it is very important to find an optimal threshold value using heuristic method to recognize the dripping of the liquids. In addition, the user can adjust the dripping speed according to the doctor's prescription, exactly like watching the progress bar of a mobile application. The experiment results show that our method using video processing technique accurately measures the dripping speed for a wide range of speeds that are sufficient for ordinary practice.

Recently, the prevalence of remotely managed patient care systems in medical institutions is increasing due to COVID-19. In particular, in the case of fluid monitoring, hospitals are considering introducing it as a system that can reduce patient safety and nurses' work. There are two products under development: a load cell method that measures weight and a method that detects drops of sap by infrared sensing. Although each product has differences in operation principle, sensor type, size, usage, and price, medical institutions are highly interested in the accuracy of the data obtained.In this study, two prototypes with different sensor methods were manufactured and the total amount of infusion per hour was measured to test the accuracy, which is the core of the infusion monitoring device. In addition, when there was an external movement, the change in the measured value of the sap was tested to evaluate the accuracy according to the measurement method. As a result of the experiment, there was a difference of less than 5% in the measurement value error of the two devices, and the load cell method showed a difference in the low-capacity measurement value and the infrared method in the high-capacity measurement value. As a result of this experiment, there was little difference in accuracy according to the sensor method of the infusion monitoring device, and it is considered that there is no problem in accuracy when used in a medical institution.

It was reported that there were some cases in which signal was not inhibited but high signal appeared in cerebrospinal fluid on FLAIR(fluid attenuated inversion recovery) of MRI(Magnetic Resonance Imaging) in case a person inhales high-concentration oxygen. This study was to prepare basic database. We produced a phantom fixed with agar gel and by using it, obtained the images of the signals of normal saline into which oxygen was injected and normal saline diluted with contrast media by changing the TI(Inversion Time) of FLAIR technique and analyzed them. In the result of FLAIR technique of MRI using Philips Achieva MR 3.0T in Busan P Hospital, the SNR(Signal to Noise Ratio) of normal saline into which oxygen was injected was higher than the SNR of normal saline into which oxygen was not injected. However, it was not higher than the SNR of normal saline diluted with contrast media. In the TI 1,800ms, we could obtain the images which do not have the rise of the signal due to oxygen. In the CNR(Contrast to Noise Ratio) of normal saline into which oxygen was injected and normal saline diluted with contrast media as well, it was higher in the TI 1,800ms than in the TI 2,800ms that is mainly used clinically. It is thought that the result of this study could be basic database for studies on change of signal of cerebrospinal fluid as a result of injection of oxygen in FLAIR technique of MRI.
