This study is a nonequivalent control group pretest-posttest design to verify the effect of music listening on convergent job stress of experimental group of 40 who are listening to music 10 times and control group of 40 who are taking a rest in fire-fighters. Homogeneity test and distribution of high risk and low risk were analyzed using Chi-test and the effect of listening to music on job stress was analyzed using t-test with SPSS 22.0 program. The experimental group showed a decreased job stress more significantly than the control group. Therefore, job stress intervention program should be developed and practical and systematical approach to reduce the job stress using music listening aggressively should be prepared in the future based on this study's result.

An integrated command system is critical for the safety of firefighters and effective work in the headquarters of a special disaster areas such as natural disaster or large man-made hazard. The integrated command system requires environmental information such as temperature, humidity, and $CO_2$ levels, as well as personal physical information such as pulse and air respirator levels. An Analog to Digital Converter (ADC) chip converts sensed information into digital signals, and a Micro Controller Unit (MCU) transmits the digital signals to a transmission board using serial communication through a Serial Peripheral Interface (SPI). The digital signals are saved in a transmission board and transmitted to the integrated command system by a Radio Frequency (RF) unit. The location of fire-fighters in a building are determined using a gyro sensor and an inertial sensor. The collected information is applied to the integrated command system for firefighter safety and to ensure that they can effectively carry out their duties. Tthis study theoretically and experimentally investigated the technologies of RF transmission, indoor position, and an integrated command system that supports decision making using the transmitted information.

본 연구는 소방대원의 현장 작업자세 평가와 분석을 통하여 소방대원의 근골격계 부담작업 유해요인을 분석하고자 한다. B시에 소재하고 있는 소방서의 남자 소방대원을 대상으로 소방 현장에서 많이하는 자세 중 요구조자 이송작업자세, 방수작업자세, 유압구조장비 작업자세, 만능도끼작업 자세를 인간공학적 평가 기법인 Rapid Entire Body Assessment(REBA), Rapid Upper Limb Assessment(RULA)와 NIOSH Lifting Equation(NLE)를 이용하여 평가하고 분석하였다. 자세 분석결과, RULA 분석에서 모든 작업이 최고 점수인 7점으로 평가되었고 REBA는 5점에서 10점까지로 RULA분석에 비하여 낮은 점수를 나타내었다. 따라서, 소방대원들의 작업환경과 자세에 문제가 많다는 것을 알 수 있었다.

A variety of methods for indoor positioning systems have been underway to ensure the safety of emergency rescuers who are working in dangerous situations such as fire fighters. However, since most systems display locations of rescue workers in two-dimension (2D)-based maps, it is difficult for a commander located in the outside to recognize locations of rescuers inside the building intuitively. An augmented reality (AR)-based indoor positioning monitoring system can display locations of rescuer inside the building that can be seen by commanders to help intuitive recognition of positioning. To monitor AR-based indoor positioning, it is necessary to have an estimation technique of line of sight vector of observers. In the present study, an estimation technique of a line of sight vector using ultra-wide band tranceiver installed inside the indoor to trace locations is presented.

This study presents the design and manufacture of a self-contained breathing apparatus SCBA wireless communication module with a multipoint simultaneous full-duplex communication system to enable communication between team members wearing the SCBA system. It is necessary for fire-fighters to wear the SCBA system during extinguishing and rescue work at the fire site. Evaluation of the team communication module confirmed the feasibility of communication over more than 500 m in the test condition based on the line of sight. By implementing the Ad-hoc function, it was confirmed that the communication distance could be extended to 128 m by automatic routing up to 3 hoc. The vertical distance inside the building for successful communication was up to the 5th floor in the open staircase and up to the 3rd floor in the partitioned staircase. Furthermore, the performance testing of the communication module assuming a fire situation, confirmed that five team members correctly recognized the standard abbreviation of fire and wireless communication without a separate PTT key operation. In addition, the flame resistance was verified by exposing the module to a flame at 950 ± 50 ℃ for 5 s and then immediately extinguishing the flame.

Modern fire fighting jobs have been expanded to include areas of rescue, emergency medical service as well as conventional fire suppression, so that load for fire fighting jobs has been increased. Specifically, musculoskeletal disorders (MSDs) such as low back injury have been considered as one of major industrial hazards in heavy manual material handling during fire fighting jobs. This study tried to evaluate risk levels and to prepare background for reducing risk levels associated with heavy manual material handling during fire fighting jobs. This study applied two major tools in evaluating heavy manual material handling jobs which were NLE (NIOSH Lifting Equation) and 3DSSPP (3D Static Strength Prediction Program). A risk index in terms of heavy manual material handling during fire fighting jobs was identified. This index consisted of seven risk levels ranged from nine points (the first level) to three points (the seventh level). There was no job associated with the first level (the highest risk level) of index. There was only one job (life saving job) belonging to the second level (the second highest risk level) of index. The third level had jobs such as usage of destruction equipment and lifting patient. A total of basic eighteen jobs was categorized into six different levels (2nd-7th levels) of index. The outcome of the study could provide a good basis for conducting job intervention, preparing good equipment and developing good education program in order to prevent and reduce MSDs including low back injury of fire fighting jobs.

This study was designed to identify the extent of incident shock who are in high risk of post traumatic shock stress, and analyze the related factors that affect the extent of incident shock. The subjects are 415 rescue workers from Seoul Metropolitan Fire & Disaster Headquarters, who are in high frequency of fire outbreaks and rescue mobilization. With a reliability of Cronbach's ${\alpha}$=.975, the results show invasion, avoidance, sleep disorder and emotional paralysis, dissociative symptom, hyper arousal as foremost causes respectively. Moreover, the results imply that the extent of incident shock was higher in people with more age or being married. Also, from the occupational perspective, the number of years as fire fighters, as rescue workers, mobilization and experiences at work in proportion to incident shocks has risen exponentially. It is notable that the groups who alleviate stress by consuming liquors had higher extent of incident shock. In conclusion, to deal with groups in high risk, management system and prevention care programs for incident shocks need to be introduced immediately and put into effect.
