<P>We conducted in-depth interviews with 11 Korean Disaster Relief Team (KDRT) members about stress related to disaster relief work and analyzed the interview data using the Consensual Qualitative Research (CQR) method in order to evaluate difficulties in disaster relief work and to develop solutions to these problems in cooperation with related organizations. Results showed that members typically experienced stress related to untrained team members, ineffective cooperation, and the shock and aftermath of aftershock experiences. Stress tended to stem from several factors: difficulties related to cooperation with new team members, the frightening disaster experience, and the aftermath of the disaster. Other stressors included conflict with the control tower, diverse problems at the disaster relief work site, and environmental factors. The most common reason that members participated in KDRT work despite all the stressors and difficulties was pride about the kind of work it involved. Many subjects in this study suffered from various stresses after the relief work, but they had no other choice than to attempt to forget about their experiences over time. It is recommended that the mental health of disaster relief workers will improve through the further development of effective treatment and surveillance programs in the future.</P>

Objective Endotracheal intubation is extremely difficult to perform in patients wearing a cervical collar for a head and neck injury. Therefore, we analyzed actual measurements using the look externally, evaluate 3-3-2, Mallampati score, obstruction, and neck mobility (LEMON) criteria before and after cervical collar application to investigate the causes of a difficult airway. Methods This simulation study was performed in 76 healthy volunteers. We measured the mouth opening, modified Mallampati classification, and neck extension before and after cervical collar application. Results The mean inter-incisor distance significantly decreased from 4.3 to 2.6 cm (P<0.001). Fifty-seven participants classified as I and II were newly classified as III and IV according to the modified Mallampati classification after cervical collar application (16% to 91%). The angles of neck extension significantly decreased from 44° to 22° after cervical collar application (P<0.001). Before cervical collar application, our simulations predicted that 14 of 76 participants (18%) would have a difficult airway, whereas after cervical collar application, 76 of 76 (100%) were predicted to have a difficult airway. Conclusion All values for the LEMON criteria (mouth opening, modified Mallampati classification, and neck extension) worsened significantly after cervical collar application. Additionally, a difficult airway was predicted in all participants after cervical collar application.

High Dynamic Range Imaging On Digital Still Camera

Film photographers had used to "dodge and burn" to express a greater dynamic range than original photographic paper. The greater dynamic range imaging is a big challenge on general digital camera area. In this paper, we propose a solution to generate a high dynamic range (HDR) image on a digital still camera, considering a minimum resource and a variable dynamic range capturing. Our approach consists of three parts: scene capturing, HDR image generation and DR compression. The scene capturing needs an adaptive controlling of the exposure time during multiple captures. The HDR image generation from multiple captured images has to preserve and combine the captured dynamic range data for storage and display having low dynamic range (LDR). Our research is implemented onto a commercialized camera system and is evaluated by the maximum capturing dynamic range and the HDR image quality.

Response to the COVID-19 Outbreak in The Emergency Department Designed for Emerging Infectious Diseases in Korea

Background: According to the recent coronavirus disease 2019 (COVID-19) pandemic experience, many emergency departments experience difficulties in responding to emerging infectious diseases and this has led to a public health crisis. Our emergency department (ED) is designed to respond to mass outbreaks of infection. Three major preparations were taken to respond to infectious disease; first, to improve the emergency department facilities; second, to created programs to respond to each phase of an epidemic of COVID-19; lastly, to implemented education and training to promote the safety of medical staff. We would like to share the actual responses and statistics of patients visiting emergency department during COVID-19 periods of pandemic. Materials and Methods: This research was conducted through a retrospective chart analysis provided by a public medical center with 502 beds since the first report of a COVID-19 confirmed case on January 19, 2020 to June 15, 2020 in Seoul, the capital of Korea. Our emergency department was designed based on Korean Regional Emergency Center Facility Standards, and modified throughout each phases of COVID-19 outbreak. Patients suspected to be infectious are screened in the triage, separating them from general patients, and then receive isolation treatment in isolated wards. Results: A total of 4,352 patients visited the ED. 3,202 screenings were conducted with 5 confirmed cases. Another 1,150 patients were treated with general emergent symptoms. There were no problems such as closure of the emergency department or isolation of medical staff while managing COVID-19 confirmed patients. Conclusion: Improving emergency department facilities, create an operational program to respond to each phase of COVID-19 outbreak and implement educational programs enabled large number of screening tests and hospitalization for COVID-19 suspected patients while maintaining general medical services. Research in emergency department designs and operational programs should increase to combine research data with better ideas to respond not only during regular periods but also during periods of pandemic.
