Korean people use a lot of herbal agents for medical purposes, such as curing diseases, improving health state, but some of the herbal agents have toxic side effects. In terms of toxicology, herbal agents classified into 3 categories generally nontoxic, potentially toxic and toxic. But, there are few studies about the mechanisms and clinical features of intoxication of herbal agents. So detoxification or initial treatment of these agents is very difficult to clinicians in hospital. Authors experienced an uncommon case of intoxication after Arisaematis Rhizoma Ingestion. We report this case with review of Arisaematis Rhizoma.

Amitraz is a formamidine-derived insecticide and acaricide which is commonly used throughout the world. Amitraz intoxication is mediated through ${\alpha}_2$ adrenergic receptor agonist effects, similar to those of the ${\alpha}_2$ agonist clonidine. We report a case of a patient who experienced coma and hypotension after amitraz ingestion. A 37-year-old woman visited the ER with symptoms of vomiting and altered mental state. She had ingested a mouthful of liquid amitraz concentrate (12.5%), which rapidly led to vomiting, hypotension, bradycardia, hyperglycemia, and mental stupor. Supportive treatment, including mechanical ventilation and administration of inotropics, resulted in full recovery within four days.

Building resilient community is often a complicated process to be gained by interorganizational collaboration. Since patterns of interorganizational relations among governments and sectors are constantly changing due to internal and external factors in the field of emergency management, understanding the dynamic nature of interorganizational collaboration is a critical step for improving a community’s ability to bounce back from a catastrophic event. From two theoretical perspectives, this research aims to examine the essential role of working across levels of governments and sectors in building resilient community by focusing on sources of community resiliency and a strong commitment. The empirical evidence highlights the importance of studying resilience as a way to understand the motivation and incentive for organizations to work jointly during emergency response. The study of organizational resilience also draws attention for the importance of various forms of interorganizational collaboration such as formal and informal relations. It also highlights how local organizations can utilize their relations to seek resources without necessarily jeopardizing their ability to perform their core organizational functions.

Herein, we report a case of emergency cesarean section after severe maternal drug intoxication in late pregnancy. At a 38-week-gestation, a 32-year-old woman with a 10-year history of bipolar disorder took olanzapine (200 mg), diazepam (20 mg), and zolpidem (200 mg) as part of a suicidal attempt. Given her unconscious state and the evident concern regarding the toxic effects of the drugs on the fetus, a cesarean section was performed immediately. The patient gave birth to a male baby with Apgar scores of 5 at 1 and 8 at 5 minutes. The baby showed dyspnea and decreased activity directly after birth. After supportive care, the condition of both mother and baby improved and both were discharged.

While emergency operating procedures (EOPs) occupy an important role in the management of various abnormal situations in nuclear power plants (NPPs), current technology for the validation of EOPs still largely depends on manual review. A validation method for EOPs of NPPs is thus proposed based on dynamic multi-level flow modeling (MFM). The MFM modeling procedure and the EOP validation procedure are developed and provided in the paper. Application of the proposed method to EOPs of an actual NPP shows that the proposed method provides an efficient means of validating EOPs. It is also found that the information on state transitions in MFM models during the management of abnormal situations is also useful for further analysis on EOPs including their optimization.

This study is implemented in the Department of Emergency Medical Technology of the Cheju Halla College in to evaluate behavioral changes in the recognition of the importance of the first aid, coping ability in the field, and competence of the first aid skills after taking the in-service program. The in-service program was hold from December 14 to December 22, 1998 under the title of "1998 First Aid and Emergency Rescue Training" for 176 drivers. The Questionnaire was distributed to 176 drivers, among them, 88 drivers took in-service program and 88 ones did not. After the data analysis, following conclusions we re made. 1. There are no significant statistical differences among demographic factors such as the level of education, age, career, and marital state of the subjects in the recognition of the importance of the first aid and competence of the first aid skills. 2. The drivers, who were the in-service program, significantly higher score in educated in represented all the area of recognition of the importance of first aid than non-educated drivers. 3. The drivers, who were educated in the in-service program, showed also significantly high score in competence of the first aid skills. According to the conclusions, there were significant change made In the recognition of the importance of the first aid and competence of the first aid skills after the in-service program. Therefore, nationwide emergency training program should be considered to improve emergency care ability of the nation. To make the program more effective for drivers, the in-service program should be required to newly licensed drivers during orientations or licence issuing.

Purpose: Although glyphosate-surfactant herbicide intoxication is relatively mild toxic in humans, we encountered an atypical clinical presentation. We performed this study to understand the atypical clinical course and factors associated with severe intoxication after glyphosate ingestion. Methods: We conducted a retrospective study of 61 patients (male 43, mean age $54{\pm}18.8$ years) who were presented with glyphosate ingestion between March 1997 and March 2011. The severe intoxication group was defined as patients with systolic blood pressure less than 90 mmHg, respiratory distress needing intubation, or altered mental state. Results: Of the 61 patients, 22 patients (36.1%) had a severe clinical course, 1 patient (1.6%) had died and 1 patient (1.6%) had moribund discharge. The most common symptoms were nausea with or without vomiting which occurred in 30 patients (49.2%). Twenty-seven patients had metabolic acidosis that was the second most common medical complication. Advanced age, pH, base excess, $HCO_3$, Sat, creatinine, X-ray abnormalities and ECG abnormalities were significant factors. Hemoglobin, platelet, $pO_2$, $pCO_2$, BUN, sodium, potassium and AST levels were not different comparing the laboratory characteristics between the severe and mild intoxication groups. Conclusion: The results of this study showed that severe intoxication occurred in 22 patients (36.1%) after glyphosate intoxication. Advanced age, pH, base excess, $HCO_3$, Sat, creatinine, X-ray abnormality and ECG abnormalities were significant predictive factors for severe intoxication in patients with glyphosate surfactant herbicide poisoning.

This paper proposes and implements a LoRa-based emergency exit guide system which can direct the optimal refuge path accounting for the real state of the fires. Each 4-way emergency exit guide sign presents a right direction through one of four LED signs toward the possible exit dynamically calculated by the shortest path algorithm. We constructed a simulation environment with 8 spots of the emergency exit guide signs and 2 exits, which can simulate variant cases of fire accidents, and showed that the proposed algorithm can presents the right guidance for each emergency exit guide sign. We also evaluated the performances of LoRa-based wireless communications using a self developed communication module in the various indoor and outdoor environments. The proposed system can be applied to small and medium sized buildings as well as larger ones in terms of cost efficiency, in which there's no needs to invest for the complex equipments except only sensors and emergency exit guide signs.

Methylene blue is the first choice for treating methemoglobinemia, any increase in normal methemoglobin levels. Methemoglobin is an abnormal hemoglobin in which the iron has been oxidized to the ferric(+3) state, making it incapable of oxygen transport. Methemoglobinemia most commonly results from exposure to oxidizing chemicals, but may also arise form genetic, dietary, or even idiopathic etiologies. Patients with low methemoglobin levels are asymptomatic, but high methemoglobin levels can lead to headaches or even death. Methylene blue, the first-line treatment for methemoglobinemia, can also produce hemolytic anemia. Jaundice or dark urine during methylene blue treatment may indicate hemolytic anemia. A 47-year-old female patient with a history of depressive mood disorder developed significant methemoglobinemia after ingesting a Propanil overdose. Twenty-two hours after ingestion, methemoglobin levels in the blood were 73.2%. She was treated with intravenous methylene blue in the therapeutic range (1 mg/kg every 4 h for 3days). The 2nd day after methylene blue use, methemoglobin levels in the blood were 33%, and the 5th day decreased to 10% with better general condition. The patient had hyperbilirubinemia after hemolytic anemia, but she recovered completely.

Purpose: The number of glyphosate and glufosinate intoxication cases are increasing in Korea. This study was undertaken is to compare the clinical manifestations of poisoning by these two herbicides and to document severities and clinical outcomes. Methods: We retrospectively evaluated cases of glyphosate or glufosinate intoxication among patients that visited our emergency department between January 1, 2013, and December 31, 2017. Incidences of intoxications were analyzed over this five year period, and underlying diseases, transportation, mental state, shock occurrence, inotropics, gastric lavage, charcoal administration, intubation and ventilator therapy, and hemodialysis were investigated. In addition, we included transfer to the intensive care unit, incidences of pneumonia and of other complications, death, and hopeless discharge. Results: There were 119 cases of glyphosate intoxication and 42 of glufosinate intoxication. Levels of consciousness were lower for glufosinate and vasopressor usage was higher due to a high shock rate (p=0.019). In addition, many patients were referred to the ICU for intubation and ventilation. The incidences of pneumonia and of other complications were significantly higher for glufosinate. Conclusion: Overall glufosinate intoxication was found to be more severe than glyphosate intoxication as determined by complication and ICU admission rates.
