The recent Middle East respiratory syndrome coronavirus (MERS-CoV) outbreak has originated from a failure in the national quarantine system in the Republic of Korea as most basic role of protecting the safety and lives of its citizens. Furthermore, a number of the Korean healthcare system's weaknesses seem to have been completely exposed. The MERS-CoV outbreak can be considered a typical public health crisis in that the public was not only greatly terrorized by the actual fear of the disease, but also experienced a great impact to their daily lives, all in a short period of time. Preparedness for and an appropriate response to a public health crisis require comprehensive systematic public healthcare measures to address risks comprehensively with an all-hazards approach. Consequently, discussion regarding establishment of post-MERS-CoV improvement measures must focus on the total reform of the national quarantine system and strengthening of the public health infrastructure. In addition, the Korea Centers for Disease Control and Prevention must implement specific strategies of action including taking on the role of "control tower" in a public health emergency, training of Field Epidemic Intelligence Service officers, establishment of collaborative governance between central and local governments for infection prevention and control, strengthening the roles and capabilities of community-based public hospitals, and development of nationwide crisis communication methods.

Methylene blue is a very effective reducer of drug-induced methemoglobinemia. It has dose-dependent oxidation or reduction properties. In most cases, a dose of 1 to 2 mg/kg IV given over 5 minutes and immediately followed by a 15- to 30-mL fluid flush to minimize the local pain is both effective and relatively safe. The onset of action is quite rapid, and the effects are usually seen within 30 minutes. The dose may be repeated after 30 to 60 minutes and then every 2 to 4 hours as needed. The total dose should not exceed 7 mg/kg as a single dose or 15 mg/kg within 24 hours. Repeated treatment may be needed for treating compounds that have prolonged elimination or those compounds that undergo enterohepatic recirculation (e.g., dapsone). Methylene blue can cause dose-related toxicity. At high doses, methylene blue can also induce an acute hemolytic anemia and rebound methemoglobinemia. The reasons for treatment failure with methylene blue include ineffective GI decontamination, the existence of other forms of hemoglobin (e.g., sulfhemoglobin), a low or high dose of methylene blue and the toxicokinetics of some agents, such as aniline, benzocaine or dapsone.

Since 1995, One of the NGIS(National Geographic Information System) projects, the underground utilities project has been finished in 2003. The 19 cities in korea for this project will use underground utilities management system using underground utilities database focusing on water and sewage system. However, special expert, technical and experience problem in computer environment has not been had in working department for water and sewage management and maintenance for each local government. The management and maintenance of underground utilities database by manual method is getting lowered a data quality of underground utilities database because of the data omitting, error in writing and securing of the lasted database. Therefore, in this study, Application test for field workers using a mobile tool and environment analysis of wireless communication in Korea and application test of GPS receiver for mobile tools had been processed and made a mobile working environment. The efficient management and maintenance method for underground utilities database has been developed an off- line method for modification and update of database about general work which has a high working frequency because of the limitation of wireless communication environment Also, the emergency working has been applied for on-line method.

Geographic information system (GIS) sewer network data are a fundamental input material for urban inundation modeling, which is important to reduce the increasing damages from urban inundation due to climate change. However, the essential attributes of the data built by a local government are often missing because the purpose of building the data is the maintenance of the sewer system. Inconsistent simplification and supplementation of the sewer network data made by individual researchers may increase the uncertainty of flood simulations and influence the inundation analysis results. Therefore, it is necessary to develop a basic algorithm to convert the GIS-based sewage network data into input data that can be used for inundation simulations in consistent way. In this study, the format of GIS-based sewer network data for a watershed near the Sadang Station in Seoul and the Oncheon River Basin in Busan was investigated, and a missing data supplementing algorithm was developed. The missing data such as diameter, location, elevation of pipes and manholes were assumed following a consistent rule, which was developed referring to government documents, previous studies, and average data. The developed algorithm will contribute to minimizing the uncertainty of sewer network data in an urban inundation analysis by excluding the subjective judgment of individual researchers.

Plastibell is one of the three most common devices used for neonatal circumcision in the United States, with a complication rate as low as 1.8%. The Plastibell circumcision device is commonly used under local anesthesia for religious circumcision in male neonates, because of cosmetic reasons and ease of use. Occasionally, instead of falling off, the device may get buried under the skin along the shaft of the penis, thereby obstructing the normal flow of urine. Furthermore, the foreskin of neonates is highly vascularized, and hence, hemorrhage and infection are possible when the skin is cut. Necrosis of penile skin, followed by urethral obstruction and renal failure, is a serious surgical mishap requiring immediate corrective surgery and medical attention. We report a case of fulminant urosepsis, acute renal failure, and pyelonephritis in a 4-day-old male neonate secondary to impaction of a Plastibell circumcision device. Immediate medical management was initiated with fluid resuscitation and mechanical ventilation; thereby correcting life threatening complications. Pediatricians and Emergency Department physicians should be cognizant of the complications from Plastibell circumcision device in order to institute appropriate and timely management in neonates.

Clinical features of masticator-space abscess (MSA) are very similar to those of parotitis or temporomandibular disorder (TMD), making early differential diagnosis difficult. Local causes of MSA include nerve block anesthesia, infection after tooth extraction, and trauma to the temporomandibular joint (TMJ); the systemic cause is immunodeficiency. Odontogenic causes account for most etiologies, but there are also unusual causes of MSA. A 66-year-old male patient visited the emergency room (ER) presenting with left-side TMJ pain three days after receiving an acupressure massage. He was tentatively diagnosed with conventional post-trauma TMD and discharged with medication. However, the patient returned to the ER with increased pain. At this time, his TMD diagnosis was confirmed. He made a third visit to the ER during which facial computed tomographic (CT) images were taken. CT readings identified an abscess or hematoma in the left masticator space. After hospitalizing the patient, needle aspiration confirmed pus in the infratemporal and temporal fossa. Antibiotics were administered, and the abscess was drained through an incision made by the attending physician. The patient's symptoms decreased, and he was discharged.

Objectives: The purpose of this study was to investigate the current status of and problems with the Safe Community Programs in Gangbuk-gu, one of the 25 districts of the capital city of Korea. Methods: The study subjects were 396 individuals who were involved in Safe Community Programs between 2009 and 2011. We examined the effectiveness and willingness of respondents to participate as a safety leader of the Safe Community Program with a questionnaire. We examined the injury death rates of Gangbuk-gu by using of the death certificate data of Korea's National Statistical Office. Descriptive statistics and chi-squared tests were used. Results: The effectiveness of programs did not differ but active participation differed significantly among subjects (p<0.05). The injury death rate of Gangbuk-gu as a whole increased during the implementation period. However, senior safety, in particular, may be a helpful program for reducing injuries in Gangbuk-gu. Conclusions: This study suggests that the lack of active participation may be a major problem of Safe Community Programs in Gangbuk-gu. Therefore, Safe Community Programs should be expanded to the entire district of Gangbuk-gu and more active participation programs should be developed.

The motality rate of acute subdural hematoma(ASDH) associated with closed head injury is high in spite of recent advances in neurosurgery. Many variables in regard to outcome of ASDH have been assessed. But among them, intracranial pressure(ICP) control and the time interval between injury and operative evacuation are the only things that can be affected by doctor. We introduced a simple method to the management of ASDH for reducing the time interval between injury and operation. When the immediate decompressive operation of ASDH was impossible by any causes, we made a burr hole at the center of hematoma, usually on 2-3cm above temporal squama and 1-2cm behind coronal suture under local anesthesia before main operation. Partial hematoma evacuation was achieved through the burr hole and it was effective in preventing further worsening of patients neurological status before main operation. Prompt hematoma evacuation through the burr hole seemed to be effective in delaying secondary ischemic brain damage and made easy to closing the dura opening and replacement of the bone flap at the end of main decompressive operation. This easy method may reduce the time interval between injury and operation. We represent surgical technique with two cases of ASDH managed with this simple method.

Chest pain is a symptom observed commonly in outpatients and emergency room patients, and its causes are variable. Because treatment and prognosis of chest pain are different depending on its cause, it is more important than anything else to accurately diagnose the cause of chest pain. Most of patients complaining of chest pain undergo basic tests at a private local clinic or at the Internal medicine or chest surgery department of a general hospital and, they are referred to the pain clinic, with a note stating no particular finding. However, if they have sustained severe neuropathic pain in spite of nerve block, accurate diagnosis for chest pain is essential. We experienced rapidly developing spine breakdown and cord compression caused by metastatic spinal tumor in an inpatient who was being treated for chest pain, and thus, we report here in the case with literature review.

Introduction: An unexpected death was reported in a beginner immediately after starting the work at a plating factory. After the incident, air sampling was performed using a simulation of the situation as it had been at the time. Methods: To evaluate the airborne concentration of hydrogen cyanide, a total of six samples were collected: one personal sample, three area samples, and two background samples (office and outdoors). Hydrogen cyanide measurement was performed according to the standard sampling protocol recommended by the U.S. NIOSH (National Institute of Occupational Safety and Health). Results: The highest concentration of hydrogen cyanide was 0.938 ppm measured in a sample collected from the plating bath area with local exhaust ventilation. This value was approximately 20% of the ceiling occupational exposure limit. The personal sample showed a concentration of 0.135 ppm. Samples collected near the bath in which the incident occurred and a dehydrator showed hydrogen cyanide concentrations of 0.236 ppm and 0.101 ppm, respectively. Hydrogen cyanide was not detected in the background samples (office and outdoors). Conclusions: It is necessary to use proper ventilation systems and respirators in plating factories to prevent acute poisoning. Furthermore, it is important to educate and train new workers dealing with toxic substances.
