Tele-medicine and emergency medical system are necessary for moving from an accidental point or far distance to a hospital and emergency treatment or home treatment before a hospital. Emergency treatment is extremely important in the case of death before arriving a hospital and deformed or disabled by medical treatment delay. A necessary element for this medical system is the emergency communication system. This system is on preparing for an ability of furnishing patient status to a corresponding health service by monitoring the patient at an ambulance of the accident place. This is the transportation of basic biological information of a patient to a medical center by wireless communication system and the corresponding hospital or medical center examine the patient by monitoring, then they can send emergency medical order to the patient for emergency treatment. The TRS is most efficient way of emergency medical communication system, which is currently used with popularity. In this paper studied simultaneously a way of detecting and transporting bio-logical signals, and monitoring of transporting data with communication of voice in the accident place or ambulance.

We can obtain useful knowledge from data by using a subgroup discovery algorithm. Subgroup discovery is a rule model learning method that finds data subgroups containing specific information from data and expresses them in a rule form. Subgroups are meaningful as they account for a high percentage of total data and tend to differ significantly from the overall data. Subgroup is expressed with conjunction of only literals previously. So, the scope of the rules that can be derived from the learning process is limited. In this paper, we propose a method to increase expressiveness of rules through internal disjunctive representation of attribute values. Also, we analyze the characteristics of existing subgroup discovery algorithms and propose an improved algorithm that complements their defects and takes advantage of them. Experiments are conducted with the traffic accident data given from Busan metropolitan city. The results shows that performance of the proposed method is better than that of existing methods. Rule set learned by proposed method has interesting and general rules more.

본 논문에서는 진출색(advancing color)과 후퇴색(receding color)의 개념을 알고 자동차 사고와의 관계를 알아보았다. 실제보다 더 가까이 있는 것처럼 보이는 진출색은 사고가 적음을 알 수 있고, 멀리 있는 것처럼 보이는 후퇴색이 사고가 많이 나는 것을 알 수 있다. 진출색과 후퇴색은 같은 위치에서 어떠한 색과 배경색과의 관계로서 알 수 있다. 같은 위치에서 배경색보다 더 앞으로 튀어 나올 것 같은 느낌을 주는 색을 진출색이라 한다. 반대로 더 뒤로 물러나는 것 같은 느낌을 주는 색을 후퇴색이라고 한다.

There have a lot of marine arrident doe to the increasing transportation by sea in accordance with economy growth. Accordingly, We are fully aware of the importance of the development of safety control system so that may prevent the sacrifice of life and disasters on the sea. The objective of this research in to investigate the more effective system by establishing the prevention of safety accident and marine information system as a national project.

$\ulcorner$Ministry Of Maritime Affairs And Fisheries$\lrcorner$was established on 8 August 1996 by emerging ex-$\ulcorner$Maritime and Port Administration$\lrcorner$, $\ulcorner$Fisheries Administration$\lrcorner$and some other marine-related organs such as $\ulcorner$Maritime Police Agency$\lrcorner$, $\ulcorner$Marine Accident Inquiry Agency$\lrcorner$, etc., for the purpose of enhancing development of national marine polices in various aspect and promoting marine safety and environmental protection activities. Therefore, the unification of marine casualty statistics is required for the need of appreciating present condition and problem. This paper shows the Client/Server computing system which could replace the existing Main Frame system set up by Maritime and Port Administration and Marine Accident Inquiry Agency. It also gives the way to connect every casualty related organ for data exchange of casualty information and INTERNET for opening casualty information to the public. So, applicable techniques and basic policy direction is dealt with.

The personal mobility Sharing service is currently active. Especially, electric scooters are widely utilized because they can move comfortably at a high speed over a short distance with a simple driving method. Its driving method is easy, but there is no protection device to protect the bare body. So, there is a greater accident than other means of transportation, and if two people are on board, there is higher accident probability. However, since there is no specific ways to prevent multi-person boarding yet, we propose a multi-person boarding detection model using tilt and pressure sensor. The proposed method measures the tilt degree and direction by using a tilt sensor installed in the center of the board plate and detects multi-people riding.

The purpose of this study is to collect and analyze information related to water leaks that cannot be easily accessed, and utilized by using the news search results that people can easily access. We applied a web crawling technique for extracting big data news on water leakage accidents in the water supply system and presented an algorithm in a procedural way to obtain accurate leak accident news. In addition, a data analysis technique suitable for water leakage accident information analysis was developed so that additional information such as the date and time of occurrence, cause of occurrence, location of occurrence, damaged facilities, damage effect. The primary goal of value extraction through big data-based leak analysis proposed in this study is to extract a meaningful value through comparison with the existing waterworks statistical results. In addition, the proposed method can be used to effectively respond to consumers or determine the service level of water supply networks. In other words, the presentation of such analysis results suggests the need to inform the public of information such as accidents a little more, and can be used in conjunction to prepare a radio wave and response system that can quickly respond in case of an accident.

This study was conducted on workers in high risk groups. And the effects of improper equipment wear on the recognition of safety accidents and job exhaustion. In addition, the mediating effect of the recognition of safety accident risk was identified. The results of the analysis are as follows. Because high-risk workers wear inappropriate equipment, emotions are depleted and personalization problems arise. And the mediating effect of the recognition of safety accident risk. Therefore, there is a need to provide generous support to ensure that high-risk workers are able to work properly in hazardous workplaces, so that they can wear appropriate equipment to defend the risks.

Since the marine accidents increase with the increased volume of traffic, preventive surveillance technology for safety navigation of the ships before the accident is being emphasized to secure the safety at sea along with post-accident measures. This paper aims to suggest a design based on an integrated safety management platform systems to support nautical safety, implements of bridge operation terminal equipments and alarm system for bridge watch monitoring and abnormal state of navigation/propulsion/machinery/power, and performs a quality evaluation for the actual boarding on the ship based on the classification standards.
