Recently, microcomputer technology has been developed rapidly and it provides not only graphic user interface that can be fraendly accessable but also large storage capacity to han- dle much hospital information. Almost all the order communication system for hospital has been developed under the concept of host and terminal environment since last 20 years. However, host-terminal system has not been successful in korea simply because most of physicians prescibe for rrlany patients a day(sometimes more than 150 patients a day). Also, under the host-terminal environment, programs are not friendly implemented for users. Since March 1991, we had developed order communication system for out-patients(named YONSEI-PC) using personal computer(PC) and local area network(LAN) . Since September 1992, we has applied succesfully in the Yonsei Cardiovascular Center, Sevrance Hospital, Yonsei University College of Medicine. This system consisted with Server and Clients which is communicated through LAN(Ethernet). The system also use the Host computer(IBM 9221 170) as a data bank and communicates to the Server with emulation card(3270 emulator, Interlink Inc., Korea) . After introducing this system, it enables patients to receive drugs witllin 20 minutes after prescription of 300-400 patients per day and it seemed to be effective system not to reduce waiting time for the patients but also to remove charge-troubling(due to His-entry of prescription) . This system also seems to be effective in terms of office automatism for hospital management. However users, usually physitions, required more friendly and easy system to operate and we thought that the most important one to successfully introduce order communication computer system in the hospital is user interface.

Objectives: This study investigated outpatient health care satisfaction and influential factors using data from the "2018 Health Care Experience Survey". Methods: Data on 6,705 participants in the Health Care Experience Survey were statistically examined using a t-test, ANOVA, and multiple regression analysis. Results: First, the level of satisfaction among outpatients was generally positive, and satisfaction among older people was high. Second, the significant factors of outpatient overall satisfaction were gender, consultation time, waiting time, reason for choosing institution, satisfaction with doctors, nurses, institutions, and the therapeutic result. Third, influential factors of intention to recommend were education, institution type, reason for choosing institution, satisfaction with doctors, nurses, institutions, and the therapeutic result. Conclusions: In order to improve the overall satisfaction of outpatients, the treatment method should be improved. For example, the doctor should devote more time for and engage in sufficient conversation with the patient, the nurse should be polite, and patients should be given easy-to-understand explanations.

Purpose: The purpose of this study was to understand the meanings and nature of living in the world among cancer patients. The present study adopted a hermeneutic phenomenological method which was developed by van Manen. Method: The participants for this study were 5 men and 6 women, who were over the age of 20 with admission or a follow up visit in the medical or surgical department. Data were collected by using in-depth interviews and observations from February to September, 2007. The contents of the interviews were tape-recorded with the consent of the subject. Result: The essential themes that fit into the context of the 4 existential grounds of body, time, space and other people were: a body that cannot be restored, a body that endures and lives, waiting in uncertainty, a valued calculation for the living day, being in a world of invisible power, reestablishing relationships, and reflection on his or her life. Conclusion: These findings revealed that living in the world is affected to varying degrees by the cancer. It is important for nurses to identify and take care of disabilities and to support the reorientation in the disintegrated life situation. The result of this study can give nurses some insight into these experiences and help promote empathetic care.

In this paper, we developed a Hospital Information System in which the business process is formalized and a wire/wireless integrated solution is used. This system consists of the administration office program, the medical office program, the ward management program and the rounds management program. The administration office program can enroll and accept patients, issue and reissue the RFID card. The medical office program inputs a medical examination and treatment, outputs a diagnosis, requests a hospitalization, retrieves the record of a medical examination and treatment, assigns the corresponding examination room to the accepted patients, and updates the number of an waiting patient and a patient number according to the examination room on real time. The ward management program handles hospitalizations and leaving hospital, a nurse's note, and an isolation ward monitoring. The rounds management program handles a medical examination and treatment, and a leaving hospital using PDA. This developed system can be built at low cost and increase the quality of the medical services highly by making it automated the medical administration automation. Also the small number of the medical staffs can manage the inpatients efficiently by using the monitoring functions.

Bckground: Adjuvant radiation therapy is commonly administered following breast-conserving surgery for breast cancer patients. Hypofractionated radiotherapy can significantly reduce the waiting time for radiotherapy, working load on machines, patient visits to radiotherapy departments and medical costs. Material/Methods: Fifty-two patients with operable breast cancer (pT1-3pN0M0) who underwent breast conservation surgery in Tehran Cancer Institute during January 2011 to January 2012, were randomly assigned to undergo radiotherapy in two arms (hypofractionated radiotherapy arm with 30 patients, dose 42.5 Gy in 16 fractions; and conventional radiotherapy arm with 22 patients, dose 50 Gy in 25 fractions). W compared these two groups in terms of overall survival, locoregional control, late skin complications and cosmetic results. Results: At a median follow-up of 52.4 months (range: 0-64 months), the follow-up rate was 82.6%. Overall, after 60 months, there was no detectable significant differences between groups regarding cosmetic results (p = 0.857), locoregional control or survival. Conclusions: The results confirm that hypofractionated radiotherapy with a subsequent boost is as effective as conventional radiotherapy, is well-tolerated and can be used as an alternative treatment method following breast conservation surgery.

Purpose: The most accepted method for the reanimation of a paralyzed face is the two-stage method that combines cross-face nerve grafting with free-muscle transfer. Although the results of reconstruction with this method are satisfactory, there is an excessive delay between the stages, which prolongs the period of rehabilitation. In order to overcome this drawback, a one- stage, neurovascular free-flap reconstruction method using free neurovascular muscle flaps is introduced. Methods: From 1994 to 2004, 35 patients with longstanding facial palsy were treated. Fifteen patients underwent the single-stage reconstruction with the latissimus dorsi muscle, and 20 patients underwent the two-stage reconstruction method with the gracilis muscle. We compared the long-term results of the two methods of reconstruction. The mean follow-up period was 28.7 months for one-stage reconstruction, and 35.2 months for the two-stage, respectively. Results: In the patient group of the single stage reconstruction, both mouth corner excursion and animation grade were markedly improved at the final postoperative visit. Moreover, the first muscle contraction occurred earlier in this group, than in the two-stage reconstruction group. However, four patients in the single stage group never achieved a first muscle contraction or mouth corner excursion. Conclusion: Facial palsy is a very challenging condition for cosmetic surgeons to deal with. Traditional methods for treatment of chronic facial palsy use a two-stage muscle flap which is time-consuming and burdensome to patients, many of whom are averse to waiting 8 to 12 months to complete the two stages. The one-stage reconstruction method described herein uses a latissimus dorsi free-flap and has demonstrated consistent positive outcomes in clinical assessments.

Due to the rapid socioeconomic development and the introduction of the national health insurance system the general population's need for health care and utilization of health care services have increased dramatically. As a result of this change. Korea is experiencing a shortage of health care facilities and health manpower, and this leads long wailing line at doctor's offices. One of the solutions of this problem could be home health care system for those who have minor health related problems. With this background, this study was conducted to look at the feasibility of a home-based prenatal care system using information superhighway and nursing informatics specialists. With the home-based prenatal care system, the pregnant woman checks her blood pressure, tests her urine for sugar and protein, and measures her body weight at home and sends the information to a hospital computer via the information networks such as public telephone line and information superhighway. Nursing informatics specialist at the hospital will go through each patient record and screen those who have abnormal values and notify them to see a doctor as soon as possible. Besides telemonitoring features, the proposed system will include tole-education capabilities for the patients so that patient can learn whatever they need to know ragarding the prenatal care via information networks. If this system develops and operates, patient can save time in terms of travel to and from the hospital and waiting time in the hospital. And the health care institute can utilize its resource more efficiently.

This study aims to understand health care consumer's information searching behavior according to their presence of chronic diseases. For this purpose, 240 patients' data of university hospital located in Seoul were collected by surveys from 9 February to 11 February 2016. For statistical analysis, we used SPSS Ver. 26.0. The main results of this study are as follows: First, Chi-square test showed that chronic patients used expert information sources and experiential information sources more than those without chronic diseases. Second, chronic patients were found to search nutrition management, exercise management, and patient case. Lastly, in the case of hospital-related searches, patients with chronic diseases searched more waiting time and medical expenses than those without chronic diseases. The significance of this study is to provide basic data for efficient information provision and establishment of marketing strategies reflecting information needs of health care consumers.

Purpose: The purpose of this study was to analyze the characteristics of patients who canceled their ED visits and to determine the factors that influence ED cancellation. Methods: Retrospective study that analyzed data from the electronic medical records(EMR) and Prehospital Care Reports(PCRs) of 305 patients who cancelled their appointments at a single emergency medical center over a six-month period from October 12, 2022, to April 12, 2023. Results: ED cancellations were 2.287 times higher if the patient presented to the ambulance after outpatient hours(09:00~17:00) (p=.007), and ED cancellations were 3.712 times higher if the patient presented to the ambulance under the influence of alcohol(p=.011). For patients' symptoms, medical diseases were associated with a 1.965 times increase in cancelled ED visits compared to other modes of transport (p=.005), while mental and chronic diseases were associated with a 67.3% decrease in cancelled ED visits compared to other modes of transport (OR=0.327, CI=[0.130-0.822], p=.018). symptomatic improvement was associated with a 2.482 times increase in presentations to a 119 ambulance compared to delayed waiting time(p=.022). Conclusion: Emergency medical centers should consider improving the legal system, such as increasing emergency medical care fees, to reduce the number of patients who cancel their appointments.
