Purpose. Radiation therapy for oncologic emergencies is an important modality in the management of cancer patients. The aim of the present study was to review the roles of RT in oncologic emergencies based on literature review. Methods. The oncologic emergencies requiring rapid treatment include superior vena cava syndrome, spinal cord compression, brain metastasis, and bone metastasis. We reviewed the literatures on the pathophysiology, diagnosis, and treatment of oncologic emergencies. Results. In this literature review, radiation therapy among treatment modalities for oncologic emergencies has been shown to be fast and very effective treatment modality for oncologic emergencies. Conclusions. Based on this review, we conclude that the literature provides support for the role of radiation therapy in the situation of oncologic emergencies. As the number of cancer patients increase, the prevalence of oncologic emergencies will increase. In the future, the development of RT techniques will provide the improvement of not only patient's quality of life but also the survival.

Conceptually, the emergency is classified as an urgency and an emergency. The Urgency is not immediately life threatening, but could become so if not resolved promptly. So, it requires prompt patient care same as in the emergency situation. However, the emergency is immediately life threatening and requires immediate action, such as calling 119 and basic life support. Most medical emergencies in the dental clinic cases are urgencies. The incidence of true emergencies is approximately 1/1,000,000. Adequate managing medical urgencies are important because the chance of encountering medical emergencies in the dental clinic is high and higher these days especially because of rapidly aging Korean society. Many dentists indicate that many dentists feel difficulties to recognize and treat medical problems. This paper reviews the concept of medical emergencies and how to cope with commonly occurring urgencies in the dental clinic such as loss of consciousness, hypoglycemia, hyperventilation syndrome. The best treatment for medical urgencies and emergencies in the dental clinic is prevention. Also, it is required to make preparation for emergency situations such as CPR education for dentists and being well-acquainted with equipment and drugs for the emergency care as well as to systemic medical evaluation, patient monitoring, and sedations for controlling patient's anxiety and pain. In this paper, simple algorithms based on guidelines for common urgencies in the dental clinic are suggested. In conclusion, every dentist has competencies to do the urgency care adequately and basic life support. Also, advanced cardiac life support is strongly recommended when sedation is performed in the clinic.

Objectives: This retrospective cohort study examined the incidence of interappointment emergencies during multiple-visit molar root canal treatments conducted by undergraduate students. Treatments performed without the use of intracanal medicament were compared to treatments that incorporated calcium hydroxide as an intracanal medicament. Materials and Methods: Interappointment emergencies, defined as instances of pain or swelling that required the patient to make an unscheduled follow-up visit, were recorded for up to 2 months after the intervention. To avoid the influence of obturation on the observed incidence of emergency visits, only unscheduled visits occurring between the start and end of the root canal treatment were included. Results: Of the 719 patients included in this study, 77 (10.7%) were recorded as experiencing interappointment emergencies. Of these emergencies, 62% occurred within 2 weeks following the most recent intervention. In the group of patients who did not receive intracanal medicament, the incidence of interappointment emergencies was 11.9% (46 of 385 patients). In comparison, this rate was 9.3% (31 of 334 patients) among those who received calcium hydroxide as an intracanal medicament (odds ratio, 1.33; 95% confidence interval, 0.82-2.15; p = 0.249). Conclusions: Interappointment emergencies may arise at any point during root canal treatment, but they most commonly occur within the first 2 weeks following intervention. The omission of intracanal medicament in multiple-visit molar root canal treatments, performed by undergraduate students, did not significantly increase the incidence of these emergencies.

Reliable human performance is a prerequisite in securing the safety of complicated process systems such as nuclear power plants. However, the amount of available knowledge that can explain why operators deviate from an expected performance level is so small because of the infrequency of real accidents. Therefore, in this study, a database that contains a set of useful information extracted from simulated emergencies was developed in order to provide important clues for understanding the change of operators' performance under stressful conditions (i.e., real accidents). The database was developed under Microsoft Windows TM environment using Microsoft Access $97^{TM}$ and Microsoft Visual Basic $6.0^{TM}$. In the database, operators' performance data obtained from the analysis of over 100 audio-visual records for simulated emergencies were stored using twenty kinds of distinctive data fields. A total of ten kinds of operators' performance data are available from the developed database. Although it is still difficult to predict operators' performance under stressful conditions based on the results of simulated emergencies, simulation studies remain the most feasible way to scrutinize performance. Accordingly, it is expected that the performance data of this study will provide a concrete foundation for understanding the change of operators' performance in emergency situations.

In a dental treatment, a dentist has to know the possibility to happen all kinds of the emergency and to prepare for managing that situation. Especially, the cardiac arrest is the most serious emergent problem. If the accident were happened, most dentists got embarrassed. The American Heart Association (AHA) is offering the Basic Life Support (BLS), Advanced Cardiopulmonary Life Support (ACLS) and Pediatric Advanced Life Support (PALS) programs for the healthcare who need to prepare the life threatening situation. The PALS is specialized to someone who participate in pediatric health-care field. This program is composed of three major emergency problems, such as respiratory emergencies, shock and cardiac arrests. The main concepts of the PALS are early recognition and systemic team approach. The purpose of this study was to introduce about PALS and to prepare response system for emergencies in the dental environment.

Background and Purpose : Emergencies in the school setting occurs frequently. Therefore, the role of first responders is important. General teachers in elementary schools are expected by first responders in school emergencies. This study attempted to assess needs and demands assessment on the first aid education of general teachers in elementary schools. Method : The subjects of this study were 71 general teachers from 8 elementary schools. Data were collected by the questionnaire during the period from March 19 to April 13, 2007. The data were analyzed through frequency, Cronbach's ${\alpha}$, Independent Two samples t-test, paired T-test, One Way ANOVA, Pearson's Correlation by SPSS win 12.0. Result : 1. It showed that 47.9%(34 persons) of general teachers answerd that they experienced emergencies in elementary school setting. Experienced emergencies were wounds(cut, laceration, abrasion etc.) 79.4%(27 persons), bleeding(including epistaxis) 64.7%(22 person), fracture(including dislocation, sprain) 44.1%(15 person), sting or bite 29.4%(10 persons). 2. It showed that 95.8%(68 persons) of subjects answerd that first aid education are necessary. Also 91.5%(65 persons) of subjects answerd that will be educated first aid if opportunities is given. 3. The total mean showed $2.39{\pm}.40$ in necessities of first aid education and $2.17{\pm}.36$ in needs of first aid education by 3 points Likert scale. Ranking 1 in necessities and needs of first aid education was bleeding control. 4. The total mean in necessities and needs of first aid education showed statistically significant differences(t = 3.453, p = .002). 5. The necessities of first aid education showed significant positive correlations with necessities and needs of first aid education(r = .521, p = .002). Conclusion : These results suggest that education program of first aid on elementary general teachers must be developed through necessities and needs assessment of first aid education and instructors must searched methods to increase needs of first aid.

Korean Government decided to establish the Ministry of National Emergency Management and has reformed the emergency management system due to Sewol ferry disaster. These efforts has been focused on the hardware rather than the software. All-hazard approach has been employed as the one of main principles in the emergency management in the United States. All-hazards approach concerns arrangements for managing the large range of possible effects of risks and emergencies. Once the priority of risks and emergencies is decided, agencies prepare for them. In addition, interagency collaboration is critical for the preparation of risks and emergencies such as cooperation with local governments instead of FEMA alone. It is necessary to consider employing all-hazard approach for the Ministry of National Emergency Management. Moreover, 'Korean All-hazard approach' should be developed in order to manage upcoming emergencies.

Background: In case of radiation emergencies, internal exposure monitoring for the members of public will be required to confirm internal contamination of each individual. In-vivo monitoring technique using portable gamma spectrometer can be easily applied for internal exposure monitoring in the vicinity of the on-site area. Materials and Methods: In this study, minimum detectable doses (MDDs) for $^{134}Cs$, $^{137}Cs$, and $^{131}I$ were calculated adjusting minimum detectable activities (MDAs) from 50 to 1,000 Bq to find out the optimal in-vivo counting condition. DCAL software was used to derive retention fraction of Cs and I isotopes in the whole body and thyroid, respectively. A minimum detect-able level was determined to set committed effective dose of 0.1 mSv for emergency response. Results and Discussion: We found that MDDs at each MDA increased along with the elapsed time. 1,000 Bq for $^{134}Cs$ and $^{137}Cs$, and 100 Bq for $^{131}I$ were suggested as optimal MDAs to provide in-vivo monitoring service in case of radiation emergencies. Conclusion: In-vivo monitoring program for emergency response should be designed to achieve the optimal MDA suggested from the present work. We expect that a reduction of counting time compared with routine monitoring program can achieve the high throughput system in case of radiation emergencies.
