Impossible differential cryptanalysis(IDC) introduced by Biham et. ${al}^{[4]}$ uses impossible differential characteristics. There-fore, a security of a block cipher against IDC is measured by impossible differential characteristics. In this paper, we pro-vide a wildly applicable method to find various impossible differential characteristics of block cipher structures not using the specified form of a round function. Using this method, we can find various impossible differential characteristics for Nyberg's generalized Feistel network and a generalized RC6-like structure. Throughout the paper, we assume round functions used in block cipher structures are bijective.ctive.

The AED (Automated External Defibrillator) is not evaluated for spatial accuracy and temporal availability even if it is located within a building or a specific area that needed necessary to partition by spatial analysis and location allocation analysis. As a result of the analysis, the spatial analysis was performed using the existing public data of AED with applied the GIS location analysis method. A public institution (119 safety center, police box) was selected as a candidate for a public AED base that can operate 24 hours a day, 365 days a year according to the characteristics of each residential area. In addition, Thiessen Polygons were created for each candidate site and divided by regions. In the analysis of the service was analyzed regional in terms of accessibility to emergency medical services in consideration of the characteristics of AED, that emergency vehicles could arrive within 4 minutes of the time required for emergency medical treatment in most areas of the study area, but it did not areas outside of the city center. As a result, It was found that the operation of the AED base service center centered on vehicles of public institutions is effective for responding to AED patients at night and weekend hours. 19 Safety Center under and police box the jurisdiction of Daegu City to establish an AED service center for public institutions, location-based distance, attribute analysis, and minimization of overlapping areas that the method of using a vehicle appeared more efficient than using the existing walking type AED.

The purpose of this study is to understand the causal relationship between the safety behavior of delivery man and safety awareness, work environment, and occupational stress, to derive factors for enhancing safety behavior, and to manage them with priority. It seeks to provide basic data on the factors. In this study, with the help of a community site for delivery man, we conducted a questionnaire survey of a total of 119 delivery man working at distribution centers. Questionnaires were created using safety behavior, safety awareness, work environment, and occupational stress measurement tools created using survey questions from other studies. As a result of the analysis, there was a significant difference between safety education and the experience of accidents associated with working period. In addition, there was a significant correlation between safety behavior due to conflicts related to occupational stress, safety awareness and safety behavior, and safety behavior due to the safety system in the work environment. As a result, we investigated whether it was an accident and the factors that influence safety behavior, and concluded that appropriate improvements were needed.

In Korea, exposure to stress has been accompanied by mental pain in the process of achieving many growth along with rapid development, various social problems, and the frequency of emergency hospitalization is increasing.. In the case of mentally ill patients, "unwanted hospitalization" is a problem, and police and 119 paramedics try to suppress the body of mentally ill patients, and many problems are exposed This is because the constituent requirements of the provisions of emergency hospitalization under the Mental Health and Welfare Act do not reflect reality, and each institution has a different position on one mentally ill person, and emergency hospitalization does not proceed smoothly or leads to friction between related organizations, and the safety of the mentally ill or others is not secured. Emergency hospitalization is defined as "a person who finds a person who is presumed to be mentally ill and is at high risk of harming his or her health or safety or others," and if the situation is so urgent that he or she cannot afford time to go through the hospitalization procedure to decide on his or her own hospitalization, he or she can request emergency hospitalization with the consent of a doctor and a police officer. In this case, 119 paramedics are escorted to a psychiatric institution. This provision of emergency hospitalization poses many problems in the process of transferring to psychiatric institutions. If a police officer or 119 paramedics in charge of practice use "physical force" during the emergency hospitalization process, side effects will inevitably occur, and professional negligence can be a problem. Specifically, when exercising physical force, the minimum necessary physical restraint based on laws and regulations and proportional principles is required, and the lack of the duty of care of 119 paramedics or police officers under the laws and regulations will eventually be resolved by applying other laws and regulations. Accordingly, it will be an opportunity for mentally ill patients to be transferred to psychiatric institutions in a safe environment by changing the subject of emergency hospitalization provisions under the Mental Health Welfare Act, defining and prescribing the use of physical protection guards as the enforcement regulations of the Mental Health Act, setting the duty of care for 119 paramedics and police officers, and creating an environment for transportation so that mentally ill patients can be treated safely.

Purpose This study is to investigate regional characteristics of 119 ambulance dispatch and the relationship between the distance and response time to the scene. Methods This study was retrospectively conducted 119 running sheets with 1,321 patients who had been transferred to the hospital by 119 ambulance during ambulance attendant training. The training was performed at two, five and three fire station in Seoul, Daejeon and Chungnam respectively, from June 24, 2013 to July 19, 2014. Results Almost the emergency medical services provided were no more than basic first aid in all regions. The patients transferred by 119 ambulance in Seoul were more than other region. The time of call to scene and scene to hospital were the slowest in Chungnam. The major reason of call 119 was due to disease in Seoul and Daejeon, however due to injury in Chungnam. Conclusion Our study suggests that learning from ambulance attendant training course could diverse from region to region. It is, therefore, needed that standardization of ambulance attendant training course, appropriate logistics and resource allocation for providing universal quality of emergency medical services.
