Purpose: By identifying the actual profile of emergency medical personnel's pre-admission infection control practices, this study intended to provide a basic reference material for the improvement and reorientation of pre-admission infection control measures, and thereby help establish an effective plan for pre-admission infection control activities. Methods: Total 119 EMT's working for Jeollabuk-do Provincial Fire Defense HQ were asked to join a structured questionnaire survey from June to August 2006. Results: 1. It was found that 56.1% respondents answered no guideline available on the prevention of infection. Out of our rescue brigade members who knew about relevant guideline available, 34.2% respondents answered that their department conducted quality control program for the guideline. 2. For protective outfit in emergency practice, it was found that most respondents put on gloves or nothing at all(38%), which was followed by sterile gloves(29.2%), disposable mask(26.9%), gown(4.3%) and protective goggle(1.6%). And it was noted that all respondents(100%) washed out any clothing contaminated with somatic secretion on their own. 3. For a question about any experience in emergency activities exposed to infectious diseases, it was found that most of all respondents(77.9%) answered 'No', which was followed by 'Don't Know'(18.6%) and Yes(3.9 %). 4. For a question about any experience in inquiring of patients about infectious diseases, it was found that most respondents(49.4%) answered 'Yes' and 'Sometimes'(9.1%). It was noted that 20.2% respondents had extra medical examination in medical institution in terms of whether they were exposed to infectious diseases, apart from regular medical examination. Conclusions: In order to protect 119 EMT's from infectious diseases, it will be necessary to acquire emergency medical staffs specializing in infection control and organize corresponding personnel training units to keep providing reorientation and evaluation. In addition, it will be also necessary to supply them with a full set personal protection apparatuses and other equipments required for disinfection and sterilization.

Recently, there has been a tendency for accidents occurring in manufacturing to lead to serious accidents and serious industrial accidents and to extend to community disasters. In accordance with the Third Plan (2015-2019) of the National Security Management Plan, the Safety Administration announces and promotes improvement measures to minimize industrial accidents and disasters. In the case of industrial accidents from KOSHA 2015 to 2017, the accident rate of the metal-related manufacturing industry is 1.57%, which is more than three times higher than the average 0.50% of all industries. As a result of investigating the causes of disasters, 72% of workers were found to be caused by unsafe behaviors. In addition, insecure behaviors are closely related to safety consciousness, and a survey on safety consciousness was conducted for workers in this field. Safety consciousness improvement has the affirmative effect on accident prevention and it is a factor to reduce accidents.

Purpose: The purpose of this study is to analyze the characteristics of animal carcasses treatment and quarantine management of infectious diseases of livestock, and to present the effectiveness of quarantine and follow-up management of livestock infectious diseases. Method: Actually, a livestock epidemic occurred and the burial site and burial management facility that treated livestock carcasses were visited on-site to analyze the management status and problems. Result: The burial method of livestock outbreaks of livestock infectious diseases and the long-term follow-up management accordingly requires a large amount of manpower and budget to be spent. For example, it can be seen that it is an inefficient quarantine system. Conclusion: It is necessary to review plans for the establishment of integrated livestock infectious animal carcasses treatment facilities at the level of metropolitan cities, districts, and municipalities with the government, where there is no fear of secondary infectious disease transmission and no follow-up management is required.

This study aims to identify the relationship between termite-damaged cultural heritage sites and the 'Forest Tending Project' based on a comprehensive survey of the status of damage caused by termites and of the Forest Tending Project. It was observed that the Forest Tending Project started in 2004 as a five-year policy project covering over 59% of the nation's forests, which showed the maximum value in 2009 and then gradually decreased. Since then, increased damage to national cultural heritage sites by termites has been confirmed and counter measures have been expanded since 2012. Also, as a result of the National Research Institute of Cultural Heritage surveying the status of termite damage in national cultural heritage sites over these six years, it was identified that about 98% of investigated cultural heritage sites were damaged by termites, about 78% of them were adjacent to forests, and that all 46 national cultural heritage sites which had been included in the 2008 Forest Fire Prevention Cultural Heritage Afforestation Project were damaged by termites. Therefore, it is claimed that the number of termite-damaged cultural heritage sites has increased after an extensive Forest Tending Project was applied on a national scale, and it seems that all cultural heritage areas close to forests are particularly subject to termite-damage due to the number of tree stumps and lumber byproducts which can serve as habitats for the pests.

Firefighters (who are responsible for people's safety) have one of the jobs that are expected to have problems due to aging in the workforce. An increase in the average age of firefighters can lead to serious social problems. The aim of this study is to survey firefighters in Jeollanam-do about their awareness of aging in firefighters, and to propose a plan to prepare them for aging through investigation and analysis of work problems that may occur due to an aging workforce. The survey shows that the higher the age group, the higher the awareness of aging firefighters, and the higher the total work experience and internal/external work experience, the higher the awareness of aging. As a plan to solve various problems that may arise from aging in firefighters, regular operation of physical fitness promotion programs, field work, job rotation, and managerial measures (such as a change of position to an administrative department) are prepared, and drone or robot technology is used. These solutions include the introduction of applied high-tech technologies to firefighting activities, establishment of retirement management policies, and preparation of plans to revitalize the connection to private employment. In order to maximize the applicability of the field, government institutional plans and preparations are essential.

The study analyzes the appropriate number of people per a household by applying an evacuation simulation to a 27-floor apartment in accordance with the NFPA 101 standard. The results of the analysis are as follows. First, if there are three people residing in each household, there would be 156 households in total, of which 85.25% were evacuated within 5 minutes. Second, 208 households with 4 residents were evacuated within 5 minutes. Third, if there are five people residing in each household, there would be a total of 260 households and 71.92% of residents were evacuated within 5 minutes. Lastly, 62.82% of the 312 households, each consisting of 6 people, were evacuated within 5 minutes. Measures to reduce evacuation time include determining the width of the stairs according to the number of people indoors, the number of floors in the building, the slope of stairs, and the users' characteristics, the design reflecting the ventilation conditions of the stairs, the installment of outdoor evacuation stairs, two-way stairs, evacuation lift, and the installation of an evacuation safety zone for people to evacuate outside of the building in the middle floors. In addition, measures, such as the mandatory installation of automatic emergency door open-close device to the rooftop, are required to facilitate rooftop evacuation.

Recently, the incidence of disasters and safety incidents is increasing rapidly, and the interest and demands of the people are increasing. In particular, traffic accidents in Korea are decreasing due to the continuous efforts of the government and the local governments, but still higher than the OECD average. In response to such demands of the times, the 'Regional Safety Index', a numerical value that quantifies the level of safety of each local government, is being publicized every year to awaken public awareness. The Regional Safety Index covers seven categories of accidents (traffic accidents, crimes, suicide, infectious diseases, fire, safety accidents, and natural disasters) in local governments. But, this study focuses on the traffic accident area and analyzed. The target local government is Ulju county of Ulsan Metropolitan City. Based on the traffic accident statistical data of Ulju county, the analysis of the traffic accidents and vulnerable points were analyzed. Among them, 3 key improvement districts were selected and 15 vulnerable branches were selected for each key improvement district. Next, we prepared measures for improvement of each accident vulnerable site through analysis of geographic information through traffic data related to traffic accidents and interview with related organizations. In addition, the improvement measures are divided into the structural infrastructure improvement, the institutional improvement, and the traffic safety culture movement from the viewpoint of traffic accident prevention. Finally, the implications of this study are to clarify the duties and roles of the relevant departments in the municipality, based on the implementation schedule of the improvement projects for the prevention of traffic accidents and the budget plan. In addition, it is very important that the participating agencies involved in traffic accidents and the private sector participate in the project.

There was much mass movement at many different mountain side of Peong Chang area in Kwangwon province by the influence of heavy rainfall through August/4 5, 1979. This study have done with the fact observed through the field survey and the information of the former researchers. The results are as follows; 1. Heavy rainfall area with more than 200mm per day and more than 60mm per hour as maximum rainfall during past 6 years, are distributed in the western side of the connecting line through Hoeng Seong, Weonju, Yeongdong, Muju, Namweon and Suncheon, and of the southern sea side of KeongsangNam-do. The heavy rain fan reason in the above area seems to be influenced by the mouktam range and moving direction of depression. 2. Peak point of heavy rainfall distribution always happen during the night time and seems to cause directly mass movement and serious damage. 3. Soil mass movement in Peongchang break out from the course sandy loam soil of granite group and the clay soil of lime stone and shale. Earth have moved along the surface of both bedrock or also the hardpan in case of the lime stone area. 4. Infiltration seems to be rapid on the both bedrock soil, the former is by the soil texture and the latter is by the crumb structure, high humus content and dense root system in surface soil. 5. Topographic pattern of mass movement spot is mostly the concave slope at the valley head or at the upper part of middle slope which run-off can easily come together from the surrounding slope. Soil profile of mass movement spot has wet soil in the lime stone area and loose or deep soil in the granite area. 6. Dominant slope degree of the soil mass movement site has steep slope, mostly, more than 25 degree and slope position that start mass movement is mostly in the range of the middle slope line to ridge line. 7. Vegetation status of soil mass movement area are mostly fire field agriculture area, it's abandoned grass land, young plantation made on the fire field poor forest of the erosion control site and non forest land composed mainly grass and shrubs. Very rare earth sliding can be found in the big tree stands but mostly from the thin soil site on the un-weatherd bed rock. 8. Dangerous condition of soil mass movement and land sliding seems to be estimated by the several environmental factors, namely, vegetation cover, slope degree, slope shape and position, bed rock and soil profile characteristics etc. 9. House break down are mostly happen on the following site, namely, colluvial cone and fan, talus, foot area of concave slope and small terrace or colluvial soil between valley and at the small river side Dangerous house from mass movement could be interpreted by the aerial photo with reference of the surrounding site condition of house and village in the mountain area 10. As a counter plan for the prevention of mass movement damage the technics of it's risk diagnosis and the field survey should be done, and the mass movement control of prevention should be started with the goverment support as soon as possible. The precautionary measures of house and village protection from mass movement damage should be made and executed and considered the protecting forest making around the house and village. 11. Dangerous or safety of house and village from mass movement and flood damage will be indentified and informed to the village people of mountain area through the forest extension work. 12. Clear cutting activity on the steep granite site, fire field making on the steep slope, house or village construction on the dangerous site and fuel collection in the eroded forest or the steep forest land should be surely prohibited When making the management plan the mass movement, soil erosion and flood problem will be concidered and also included the prevention method of disaster.

The current study was conducted to develop a portable composite gas detector allowing the detection of both $CO_2$ and $CH_4$ gases by means of the Non Dispersive Infra-Red (NDIR) method. The gas detector is configured to radiate infrared waves using infrared lamps, where the wavelength of the infrared light is reduced due to absorption throughout the chamber, and this reduction (absorption) is detected by the absorption detector, before being converted and amplified to a 3.5V~6V electrical signal, providing as accurate a measurement as possible. The conventional singe sensor method measures the relative measurement by absorbing only specified wavelengths of infrared radiation, which in the case of gas detection leads to problems with accuracy due to the lack of a reference sensor when detecting light with a wavelength of only $4.26{\mu}m$. The dual sensor employed in this study provides a comparative measurement between the reference value derived from the wavelength of $3.91{\mu}m$, which is not influenced by other gas sources, and the measurement value derived from the wavelength of $4.26{\mu}m$, in order to reduce the errors and enhance the reliability, thereby allowing low power consumption for portable devices and multi-gas detection for both $CO_2$ and $CH_4$ gases. The portable composite gas detector developed herein provides a measurement rage of 0ppm~5,000ppm for $CO_2$ gas, and 0.5%vol for $CH_4$, which allows the determination of whether the $CO_2$ and $CH_4$ contents in indoor air are less than 1,000ppm or not. The current study established that the composite gas detector can be interlinked with firefighting appliances through portable devices or home automation, and is anticipated to be very effective in fire prevention.

This study provides basic data needed to improve the working environment of the first class emergency medical technicians, in order to decrease their job stress and increase their job satisfaction. Job stress and satisfaction were compared and analysed in emergency medical technicians who were working for 119 rescue and hospitals at the time when twenty-one years had passed after the initial training of emergency medical technicians in order to identify differences between 119 rescue and hospitals, and their advantages and disadvantages. The subjects of the study were 182 first-class emergency medical technicians who were working in twenty-eight 119 rescue centers and fourteen national and local emergency medical centers in Gwangju, Jeollanamdo and Jeollabukdo. The study subjects were interviewed by questionnaire. For statistical analysis, SPSS/WIN 20.0 was used, and the results were analysed with chi-square, t-test, ANOVA, and ANCOVA testing. There was no significant difference in job stress between the subjects working in 119 rescue centers (2.92) and those working in hospitals(3.01). The satisfaction score of fire-fighting workers was 2.98 and that of hospital workers was 2.54. Hospital workers' satisfaction was significantly lower (p<0.001). The score of hospital workers' pay satisfaction was the lowest($2.07{\pm}0.62$). The job stress decreased and job satisfaction increased with decreasing monthly average number of patients(p<0.001), increasing monthly income(p=0.047), and more frequent holidays they had(p<0.001), the less. For less job stress and higher job satisfaction, welfare conditions both at 119 rescue and hospitals should be improved. 119 rescue centers should develop violence prevention measures and offer resting places for emergency medical technicians. Hospitals should pay more attention to the yearly pay increase rate and stability in employment types.
