Objective: This study was conducted to analyze and compare the classifications of a prehospital triage system and an in-hospital triage system. Methods: The records of patients transferred from the '119' emergency service for 5 months (from January 1 to May 31, 2016) were collected and records of first aid activities were assessed. We examined cases classified as four (urgent, semi-urgent, potentially urgent, and non-urgent) of five stages, excluding death. In the hospital, data were collected from medical records and classifications made using the five Korean Triage and Acuity Scale (KTAS) stages (1, resuscitation; 2, emergency; 3, urgent; 4, less urgent; and 5, non-urgent) were analyzed. Results: The number of patients enrolled in the study was 3,457. Of them, 2,301 were discharged after treatment and 1,156 were hospitalized. According to the prehospital triage classification, 726 of the 3,457 cases were urgent, 593 were semi-urgent, 1,944 were potentially urgent, and 194 were non-urgent. The results of the in-hospital triage were as follows: 114 KTAS 1 (3.3%), 491 KTAS 2 (14.2%), 1,345 KTAS 3 (38.9%), 1,227 KTAS 4 (35.5%), and 280 KTAS 5 (8.1%). The odds ratio trend for hospitalization showed a larger decrease according to in-hospital staging (95% CI, 0.32-0.39) than according to prehospital staging (95% CI, 0.50-0.60). The odds ratio trend for intensive care unit (ICU) admission also showed a larger decrease according to in-hospital staging (95% CI, 0.16-0.22) than according to prehospital staging (95% CI, 0.37-0.48). Conclusion: We found little correspondence in classifications made according to the KTAS and prehospital triage systems. However, the tendencies toward decreases in the hospitalization and ICU admission rates were similar.

Presented in the paper is a reservation based dispatching rule to achieve the on-time delivery in system LSI (large scale integrated circuit) semiconductor fabrication (FAB) with urgent orders. Using the proposed reservation based dispatching rule, urgent lots can be processed without waiting in a queue. It is possible to achieve the on-time delivery of urgent orders by reserving a proper tool for the next step in advance while urgent lots are being processed at the previous step. It can cause, however, tardiness of normal lots, because the proposed rule assign urgent lots first. To solve this problem, the proposed rule tries to find the best tool for the reservation in the tool group, which can minimize idle time, and the reservation rule is applied at all tools except for photolithography tools (bottleneck). $MOZART^{(R)}$ which is developed by VMS solutions are used for simulation experiments. The experimentation results show that the reservation based dispatching rule can achieve the on-time delivery of normal lots as well as urgent lots.

This study investigated college students' time management behavior and time satisfaction according to the use of the time-matrix. Data were collected from 400 college students in Seoul by a self-administered questionnaire. Collected data were subjected to descriptive and comparative statistical analyses using the software SPSS(version 12.0). The conclusions of this study were as follows; 1. The use of time-matrix was categorized into 4 task groups: (1) not urgent but important, (2) urgent but notimportant, (3) neither urgent nor important, (4) urgent and important. 2. Time-management-behavior of planning was categorized into 3 components: standard setting, reality overlapping and implementing into 3 components(i.e., checking, adjusting, facilitating condition). 3. In all domains except overlapping, 'not urgent but importance' was the most popular managerial behavior. 4. However, 'neither urgent nor important' was voted the most popular in terms of managerial satisfaction. This study provides useful knowledge on managerial time-use categorization. Furthermore also contributes towards the knowledge base of time-managerial behaviors and dispels stereotypical-thinking that only bing busy all the time using is an indication of good time management behavior. Finally, this study advocates use of the time-matrix to achieve efficient time management.

Purpose: Abdominal pain is the most common symptom of patients visiting the emergency department (ED). Abdominal pain is caused by a variety of causes, so it is difficult for a triage nurse to determine the urgency of a patient, but it is still a must. The purpose of this study was to identify the related factors to the urgent diseases of patients with abdominal pain visiting ED. Methods: This study was a retrospective descriptive study. The study setting was an ED in a tertiary hospital in Korea. Data were collected from September 1, 2017 to October 15, 2017. During the study period, of a total of 6,181 patients visiting the ED, 731 complained of abdominal pain. Patients with obvious cause of pain and patients who could not express detailed symptoms were excluded. The 573 patients were included in the final analysis. We collected demographics, clinical characteristics, and final diagnosis. We divided final diagnoses into urgent diseases which were more likely to be life-threatening without treatment and non-urgent diseases. We identified the related factors to the urgent diseases of patients with abdominal pain using the logistic regression. Results: 173 (30.2%) patients had urgent diseases. Age (OR=1.02, 95% CI=1.00~1.03), referral from other clinics (OR=2.92, 95% CI=1.86~4.60), ambulance utilization (OR=2.00, 95% CI=1.27~3.15), diarrhea (OR=0.44, 95% CI=0.25~0.76), and tachycardia (OR=2.27, 95% CI=1.44~3.58) were related to urgent diseases. Conclusion: Triage nurse should take into account the patient's age, mode of visiting, and route of visiting ED; and check the symptom of tachycardia or diarrhea.

Objectives: This study aimed to test our hypothesis that a raise in the emergency fee implemented on March 1, 2013 has increased the proportion of patients with emergent symptoms by discouraging non-urgent emergency department visits. Methods: We conducted an analysis of 728 736 patients registered in the National Emergency Department Information System who visited level 1 and level 2 emergency medical institutes in the two-month time period from February 1, 2013, one month before the raise in the emergency fee, to March 31, 2013, one month after the raise. A difference-in-difference method was used to estimate the net effects of a raise in the emergency fee on the probability that an emergency visit is for urgent conditions. Results: The percentage of emergency department visits in urgent or equivalent patients increased by 2.4% points, from 74.2% before to 76.6% after the policy implementation. In a group of patients transferred using public transport or ambulance, who were assumed to be least conscious of cost, the change in the proportion of urgent patients was not statistically significant. On the other hand, the probability that a group of patients directly presenting to the emergency department by private transport, assumed to be most conscious of cost, showed a 2.4% point increase in urgent conditions (p<0.001). This trend appeared to be consistent across the level 1 and level 2 emergency medical institutes. Conclusions: A raise in the emergency fee implemented on March 1, 2013 increased the proportion of urgent patients in the total emergency visits by reducing emergency department visits by non-urgent patients.

Energy-harvesting wireless sensor networks(EH-WSNs) can collect energy from the environment and overcome the technical limitations of existing power. Since the transmission distance in a wireless sensor network is limited, the data are delivered to the destination node through multi-hop routing. In EH-WSNs, the routing protocol should consider the power situations of nodes, which is determined by the remaining power and energy-harvesting rate. In addition, in applications such as environmental monitoring, when there are urgent data, the routing protocol should be able to transmit it stably and quickly. This paper proposes an adaptive routing protocol that satisfies different requirements of normal and urgent data. To extend network lifetime, the proposed routing protocol reduces power imbalance for normal data and also minimizes transmission latency by controlling the transmission power for urgent data. Simulation results show that the proposed adaptive routing can improve network lifetime by mitigating the power imbalance and greatly reduce the transmission delay of urgent data.

Objective : About 40% of patients who admit to the hospital after subarachnoid hemorrhage are poor clinical grade(Hunt-Hess grade IV, V). The majority of these patients have been excluded from early, aggressive treatment. The current study was undertaken to evaluate the outcome of urgent surgery for Hunt-Hess grade IV aneurysmal subarachnoid hemorrhage. Materials and Methods : We reviewed hospital records and radiographic studies of 36 patients who were Hunt-Hess grade IV among 201 cases with ruptured intracranial aneurysm admitted between Sep. 1995 and Dec. 2000. Operated patients were treated with urgent angiography and surgery within 24 hours of presentation, except six patients, and medical records of these patients were reviewed for the clinical course and Glasgow outcome scale(GOS). Results : Overall management results of the 36 patients were good recovery in 13(36.1%), moderate disability in 12 (33.3%), severe disability in 1(2.8%), vegetative state in 1(2.8%) and 9(25.0%) of surgically treated patients had died. Conclusion : Although with limited number of patients, we conclude that urgent surgery for Hunt-Hess grade IV patients results in a better neurologic outcome and urgent surgery combined with aggressive postoperative management can minimize mortality.

In many applications of wireless sensor networks, sensed data can be classified either normal or urgent data according to its time criticalness. Normal data such as periodic monitoring is loss and delay tolerant, but urgent data such as fire alarm is time critical and should be transferred to a sink with reliable. In this paper, by exploiting these data characteristics, we propose a novel energy-efficient data-aware routing protocol for wireless sensor networks, which provides a high reliability for urgent data and energy efficiency for normal data. In the proposed scheme, in order to enhance network survivability and reliability for urgent data, each sensor node forwards only urgent data when its residual battery level is below than a threshold. Also, the proposed scheme uses different data delivery mechanisms depending on the data type. The normal data is delivered to the sink using a single-path-based data forwarding mechanism to improve the energy-efficiency. Meanwhile, the urgent data is transmitted to the sink using a directional flooding mechanism to guarantee high reliability. Simulation results demonstrate that the proposed scheme could significantly improve the network lifetime, along with high reliability for urgent data delivery.

About two thirds of patients admitted to hospitals world-wide suffer from acute abdomen pains of varying degrees of severity. Acute abdomen pain due to appendicitis or pancreatitis usually requires urgent surgical treatment, whereas pain due to heart ischemia or enteroviral infection requires only drug treatment. In general, making an immediate decision about whether or not acute abdomen pain requires urgent surgery is very difficult. This decision becomes even more difficult when the patient is a young child who can't properly describe the abdominal pain. In this case, thermo-visual inspection can alternatively be used to decide whether urgent surgical treatment is necessary to cure the abdominal pain.

The data link layer of Foundation Fieldbus provides both token-passing and scheduling services for periodic, time-critical and time-available data. This study developed an analytical model that evaluates the delay performance of urgent data when the data link layer of Foundation Fieldbus provides token-passing service. The validity of analytical model is verified using an experimental model that consists of network interface boards of Foundation Fieldbus. Comparison of analytical and experimental models shows that the analytical model can be utilized in the approximate analysis of the delay characteristics of time-critical data in the Foundation Fieldbus. The analytical model can also be used in the basic design stage of Foundation Fieldbus network system.
