Recently the increase of natural disaster and man-made disaster, newly emerging infectious diseases and bioterrorism attack changed the world in many aspects. So the Ministry of Health and Welfare and other related agencies are trying to solve the problems with disasters. We discussed these problems in the following eleven categories. (1) emergency medicine (2) communicable disease control, (3) food safety control, (4) public facilities safety, (5) social welfare facilities safety, (6) bioterrorism control, (7) geriatric health care, (8) insurance support, (9) overseas disaster victim support, (10) national organization protection, (11) fire fighter safety in forest fire. Through the reviews on the various kinds of disaster, we proposed the disaster control measure for the near future.

Background: In cardiac arrest, the survival rate increases with the provision of bystander cardiopulmonary resuscitation (CPR), of which the initial response and treatment are critical. Telephone CPR is among the effective methods that might increase the provision of bystander CPR. This study aimed to describe and examine the improvement of neurological outcomes in individuals with out-of-hospital acute cardiac arrest by implementing the nationwide, standardized telephone CPR program. Methods: Data from the emergency medical service-based cardiac arrest registry that were collected between 2009 and 2014 were used. The effectiveness of the intervention in the interrupted time-series study was determined via a segmented regression analysis, which showed the risk ratio and risk difference in good neurological outcomes before and after the intervention. Results: Of 164,221 patients, 148,403 were analyzed. However, patients with unknown sex and limited data on treatment outcomes were excluded. Approximately 64.3% patients were men, with an average age of 63.7 years. The number of bystander CPR increased by 3.3 times (95% confidence interval [CI], 3.1-3.5) after the intervention, whereas the rate of good neurological outcomes increased by 2.6 times (95% CI, 2.3-2.9 [1.6%]; 1.4-1.7). The excess number was identified based on the differences between the observed and predicted trends. In total, 2,127 cases of out-of-hospital cardiac arrest (OHCA) after the intervention period received additional bystander CPR, and 339 cases of OHCA had good neurological outcomes. Conclusion: The nationwide implementation of the standardized telephone CPR program increased the number of bystander CPR and improved good neurological outcomes.

Purpose: This paper is to determine whether automatic defibrillators (AEDs) deployed across communities make a contribution to prevent death in patients with acute cardiac arrest out-of-hospital. Methods: A total of 30,179 cases of cardiac arrest investigation data from the Korea Centers for Disease Control and Prevention was matched to those on emergency medical statistics drawn from annual report for the 2018 Central Emergency Medical Center, and statistics from the National Statistical Office in 2018. Results: Multiple logistic regression analyses revealed that availability of emergency medical resources across associated with different survival rates at emergency room after taking variability of the patient's personal characteristics and episodic situational characteristics held constant. The survival rate was 1.71 times higher for patients living in communities with more than 105 AEDs avaiable per 100,000 inhabitants than for those living in communities with less than 55 AEDs. Conclusion: The survival-related factors of patients with acute cardiac arrest that occurred out-of-hospital were found to be associated with patients' and episodic situational characteristics. The hospital stage were found to be associated with patients characteristics and episodic situational characteristics, The variability of AED available in a community has an impact on survival rate after emergency room treatment.

Purpose: The purpose of the study was to investigate the causes of non-transport in 119 ambulance services and to describe the difference in response time according to the reason for non-transport. Methods: This study analyzed 42,415 non-transport cases out of 123,158 cases using prehospital care reports in a metropolitan city. The Kruskal-Wallis test and the Wilcoxon-Mann-Whitney test were used to 6,857 cases for which time was recorded. Results: Non-transportation in 20${\bigcirc}{\bigcirc}$ comprised 33.1% of all ambulance services. The reason for non-transport were other reasons (25.5%), cancellation (23.8%), and moving to other vehicles (21.7%). There were differences in ambulance service times according to the reasons for non-transport. The activation interval was the longest (2.68 minutes) in the absence of the patient, and the response interval was the shortest (4.96 minutes) among the cancelled case. The total interval was the shortest time (21.97 minutes) in the cancellation cases and the longest time among the death cases (32.23 minutes). Conclusion: It is important to suggest the direction of development of emergency services by identifying the reasons for non-transport by ambulance services and describing the response time according to the reason for non-transport.

Purpose: This study aimed to assess defibrillator pad positioning by the general public and healthcare providers during basic life support (BLS) renewal education (RE). Methods: A total 130 subjects performed defibrillation using an automated external defibrillator (AED) equipped with electrode pads developed by the researchers and male resuscitation manikins, in order to assess electrode pad placement (EPP) before BLS RE. Subjects included 54 Healthcare providers (HP) and 76 members of the general public (GP). Results: The apex EPP was positioned in the risk area (RA), more than 5 cm distant from the area recommended, by 63.2% of the GP (n = 48). The apex EPP was positioned in the RA by 44.4% of the HP (n = 23). The distance from the apex (GP $5.27{\pm}2.21cm$, HP $4.18{\pm}1.71cm$) was statistically significant, using Student's t-test. Conclusion: For both GP and HP, apex EPP was significantly in error. Thus, to prevent defibrillation failures, EPP education and practice for GP and HP in all BLS education programs should be improved, and incorrect Korean cardiopulmonary resuscitation guidelines and related literature should be revised and corrected.

Chronic liver diseases, including cancer, are characterized by inflammation and elevated serum ferritin (SF). However, the causal-relationship remains unclear. This study used primary rat hepatic stellate cells (HSC) as a model to investigate effects of physiological SF concentrations (10, 100 and 1000 pM) because HSCs play a central role in the development and progression of liver fibrosis. Physiological concentrations of SF, either horse SF or human serum, induced pro-inflammatory cytokine $IL1{\beta}$, IL6 and $TNF{\alpha}$ secretion in rat activated HSCs (all p<0.05). By contrast, treatment did not alter activation marker ${\alpha}SMA$ expression. The presence of SF markedly enhanced expression of Grp78 mRNA (p<0.01). Furthermore, transient knock down of Grp78 by endotoxin EGF-SubA abolished SF-induced $IL1{\beta}$ and $TNF{\alpha}$ secretion in activated HSCs (all p<0.05). In conclusion, our results showed that at physiological concentrations SF functions as a pro-inflammatory mediator in primary rat HSCs. We also provide a molecular basis for the action of SF and identified Grp78-associated ER stress pathways as a novel potential therapeutic target for resolution of fibrosis and possible prevention of liver cancer.

Purpose: The aim of this study was to determine the perceived needs and confidence of school nurses in health education at middle and high schools in Seoul, Korea. Methods: A descriptive survey questionnaire was developed by a research team to investigate the perceived needs and confidence across eight health education areas. A total of 329 school nurses at secondary schools in the metropolitan areas of Seoul participated. Descriptive statistics, the t-test, and ANOVA were conducted to analyze the data. Results: Generally high means in perceived education needs(Mean: 3.8~4.7/5) and health education confidence (Mean 3.3~4.5/5) were reported. However, there were significantly low means of health education confidence related to perceived needs in health education for all areas of health education. While injury prevention and emergency care education were the highest perceived educational needs and were also areas with high confidence of school nurses, mental health, social health, and sexual health were areas where nurses showed a significantly lower confidence. In general, nurses with a longer clinical experience and educational career had a higher confidence in injury prevention, emergency care, and mental health. Conclusions: Multi-level support, including the continuing education and proactive in-service training, for the school nurses needs to be developed to improve their teaching competency.

The health and medical service attracts more public attention as the economy of Korea is rapidly growing up and the standard of living is elevated. Especially, the interest and demand on the prehospital emergency medical service that consists of the important part of primary medical service that is directly related to the life of patients are gradually increased. However, as compared with other advanced countries such as America in this area, Korea actually fell behind in the utilization of IT (Information Technology) to maximize the efficiency of emergency service system as well as has a problem in the general service system. This study suggested the necessity to introduce EMD (Emergency Medical Dispatch) system that takes a great role as the core part in the prehospital emergency medical service that is not systemized in Korea yet. In addition, this study proposed the implementation model of EMD ASP system using ASP (Application Service Provider) in EMD system to flexibly deal with the change of IT and efficient implementation and integration of information system as well as to significantly reduce cost through wire/wireless high speed Internet network that is politically promoted in Korea on the basis of EMD. The system analysis and design was executed by HIPO (Hierarchy Plus Input Process Output) analysis that was the conceptual design technology for EMD information system modeling based on ASP and DFD (Data Flow Diagram). This study proposed DB table configuration and data schema to implement the application of web browser interface in EMD system through ERD(ER-Diagram) of EMD ASP system. Finally, this study described how to implement and utilize EMD information system. This study aims to facilitate the qualitative development of emergency medical service in the future as suggesting the concrete models for the implementation of high value-added prehospital emergency medical information system as applying ASP concept to EMD system of prehospital emergency medical service area.

Tuberculosis (TB) is a significant public health concern. Globally, TB is among the top 10 and the leading cause of death due to a single infectious agent. Providing standard anti-TB therapy for at least 6 months is recommended as one of the crucial strategies to control the TB epidemic. However, the long duration of TB treatment raised the issue of non-adherence. Non-adherence to TB therapy could negatively affect clinical and public health outcomes. Thus, directly observed therapy (DOT) has been introduced as a standard strategy to improve anti-TB medication adherence. Nonetheless, the DOT approach has been criticized due to inconvenience, stigma, reduced economic productivity, and reduced quality of life, which ultimately could complicate adherence issues. Apart from that, its effectiveness in improving anti-TB adherence is debatable. Therefore, digital technology could be an essential tool to enhance the implementation of DOT. Incorporating the health belief model (HBM) into digital technology can further increase its effectiveness in changing behavior and improving medication adherence. This article aimed to review the latest evidence regarding TB medication non-adherence, its associated factors, DOT's efficacy and its alternatives, and the use of digital technology and HBM in improving medication adherence. This paper used the narrative review methodology to analyze related articles to address the study objectives. Conventional DOT has several disadvantages in TB management. Integrating HBM in digital technology development is potentially effective in improving medication adherence. Digital technology provides an opportunity to improve medication adherence to overcome various issues related to DOT implementation.

Purpose: This study was conducted to identify the status of health management and to evaluate the need for health professionals in day care centers in the South Korea. Method: Data were obtained from 360 child care providers in 16 provinces from May to August, 2007. Data was analyzed using SPSS WIN 14.0. Results: Safety education (traffic. 83.8% general safety. 71.6%) was provided more often than the other topic of education. All health related education was provided by child care providers. When minor health problems occurred, the most common management strategy was to send the child home (36.1%). During emergency conditions, majority of child care providers preferred taking the children to medical centers without giving any emergency care and 19.4% reported sending the child home without any immediate care. Child care providers recognized the need for health care professionals. Conclusion: The results of this study suggest the need for services of health professionals in day care centers to satisfy the needs and expectations for health management in these centers. As health professionals, public health nurses or pediatric nurse practitioners may play an important role in health management of children in day care centers.
