Lightweight steel structure buildings are a special type of illegal building in Taiwan. There are many different types of these illegal structures in Taiwan used for various purposes. The number of factories operating in one of these illegal lightweight steel buildings alone is as high as 130,000 according to the 2017 statistics. The construction of such structures is easy, fast, and the cost is low, which is why they are widely accepted by the people.[1] The materials of a lightweight steel structure are mostly steel or C-shaped steel. When this type of steel structure is exposed to temperatures above 600 °C, the structure will begin to break and bend, causing deformation and eventually collapse. Additionally, the rapid growth of the fire, the lack of establishment on fire zones, and a fierce fire, etc., all present more challenges for onsite employees to extinguish the initial fires as well as the later fire rescue attempt by firefighters. In recent years, fatal fire incidents have been rampant, causing deaths and injury to foreign workers, highlighting fire safety issues. Therefore, “whether worker accommodation should be separated from the factory” is the subject of this paper. This study is aimed at the statistical survey of lightweight steel structures for industrial and residential use (current status): using data from project investigations to present the site overview and hazard risk factors. Risk assessment for buildings with accommodation inside the factory (validation): through the statistical survey data (34 of the 188 surveyed have accommodations inside the factory, a ratio of 18.1%), the hazard risk is assessed, and the potential risks are analyzed. Fire simulation on buildings with accommodation inside the factory (hazard): use fire simulation to analyze the effective evacuation time with residential fire alarms. To develop a disaster reduction strategy based on the results of the parametric analysis of this study for buildings with accommodation inside the factory (improvement): utilizing factory fire prevention analysis, factory symposium, fire prevention announcement, fire equipment inspection and maintenance, etc., to achieve disaster reduction. Based on the results of the parametric analysis of this study, we will develop an accommodation and disaster reduction strategy (improvement): use plant fire prevention diagnosis, factory symposium, fire prevention announcement, fire equipment inspection and maintenance, etc., to achieve disaster reduction.

Firefighters searching in dark and complex environments might lose their orientation and endanger themselves at the fireground. This study conducted experiments in the Training Facility of the New Taipei City Fire Department (NTFD), Taiwan. The objective of the experiments was to analyze the profile of each firefighter by a 13-factor self-report survey and their wayfinding time in dark and complex environments (DCEs). The results showed that age might be a marginally significant factor, and fear of confinement might be a significant factor that could affect firefighters’ wayfinding time in the DCEs. The findings could provide strategies for improving the safety of firefighters working in such environments.

In terms of the construction industry, needs of construction management will differ based on different companies, personnel, projects and time. It is very difficult to meet different construction management needs in the industry with only one system. This study aims at developing a secondary development system that allows different users to design specific and customized construction management systems according to different needs. This study is not for the provision of solutions to single "management issues" but for the development of platforms applicable to various "management types’. Consequently, management efficiency and efficacy of relevant enterprises in the industry can be raised and overall competitiveness of the industry can be enhanced. System automatic planning, construction, feedback, content adjustment, acceptance test and procedure confirmation took in total 11 months. To make sure that the problem is helpful for labor dispatch and implementation effectiveness, training courses for competent authorities, special groups and enterprises, open sharing sessions and other qualitative interviews on experience were carried out to obtain feedback of users and thereby adjust platform development. In addition, 360 system users received questionnaire investigation using technology acceptance model. Judging from 107 valid questionnaires, the average score of perceived usefulness was 4.38 and that of perceived ease of use was 4.26. In terms of average of the dimension, there was no significant difference in the background of the different respondents, indicating that most respondents were positive for the secondary development platform regarding construction management assistance and easy operation. Besides, dimensional relationships among perceived usefulness, perceived ease of use, attitude toward using and usage intention all indicate positive influence. During use of the system, feedback will be obtained through the online service platform to made adjustment and continuously offer system services, to achieve the study objectives set.

The optical properties of shear layers is a topic of research with applications in high power lasers and optical imaging systems. In recent years, it has been shown that large-scale structures are intrinsic features in a plane turbulent mixing layer. While there has been some research on the effects of turbulence on laser beams, there has been no study of the optical effects of large-scale structures as they exist in shear layer development, nor how these effects may be controlled. Since the susceptibility of a free shear layer to a forcing input increases as the location of the forcing moves closer to the trailing edge of the splitter plate. Disturbances can be imposed on shear layer using very small-amplitude displacements of the splitter-plate trailing edge in a direction perpendicular to the flow direction. We are studying the optical effects of large-scale structures in forced and unforced situations using periodic motion of a small flap at the trailing edge of the splitter plate. Three-dimensional Navier-Stokes equations in conservation law form are solved directly using the WENO scheme for the simulation of a spatially-developing free shear layer.

With the rapid development of network technology, the live video transmission system (LVTS) has improved the work efficiency because of the visual communication combining both images and data. In order to strengthen the effectiveness of disaster prevention through instant communication, the Fire Department in Taiwan has used the “VVLINK” videoconferencing system to provide multi-functional online conferences, and even grasp on-site dynamic situation of disasters in the first time, and then giving order to the disaster relief site online. Here, a research about the application of LVTS system in disaster sites was carried out to study the intention for firefighters in Fire Bureau of Changhua County, Taiwan. In this study “behavioural intension (BI)” and “usage behaviour (UB)” on LVTS system are explored through the Integrated Technology Acceptance Model (UTAUT). In addition, moderate variables such as gender, age, experience and voluntary are needed to be considered. “Performance expectation (PE)”, “effort expectation (EE)” and “social influence (SI)” can affect BI to be very significant; BI and “facilitating conditions (FC)” can also affect UB. Questionnaire analysis was applied. The results show that PE, EE, and SI have a positive direct impact on BI, and BI also has a positive direct impact on UB. It was also found that the FC had a positive and direct impact on BI as well as SI impacting on UB. All the moderate variables have significant difference on each UTAUT categories.

In this experiment, the firefighters perform the cultural assets disaster rescue drills before and after the cognitive differences as the core of the experiment. Firefighters develop education in the face of various types of building rescue training, but they lack the type of historical and historical buildings, which are fundamental in nature. The difference between the rescue target and the rescue tactics, and other types of building rescue methods can hardly be applied. The subject of this experiment is to introduce fire rescue resources (public assistance) after the failure of self-disaster prevention (self-help, co-help), and the research object is based on historical building. After many field surveys, knowledge training and actual exercises, the comparison is performed. The fire extinguishing education and training research on historical monuments can improve the effectiveness of historical monument fire extinguishing and preserve the current status of historical monuments, can list the number of cultural relics rescue personnel from 30% to 60%, can increase the number of cultural relics from 20% to 50%, can answer the answer to the room rescue from 20% to 100%, can answer the perimeter protection focus from 40% increase to 100%, can say that the focus of the water is increased from 30% to 100%. From the data, through the drills, the correct rescue concept can be greatly improved, and the secondary damage of historical sites can be avoided, but the focus of the rescue is on the cultural relics. It still needs to be strengthened, so the drills still need to be handled with perseverance in order to be more implemented and popularized.

The aging society is a challenge facing all countries in the world. The collection and analysis of fire information in elderly care institutions has become a key factor in seeking shelter time. This study will build a fire information platform and its reporting mechanism through HTML, PHP, MySQL and other software development tools, and through the source and distribution of fire information. Public announce technology to improve the fire response capacity of the elderly institutions. This paper quotes Marchant (1980), a British scholar, who regards fire and refuge action as the parameters of elderly people’s refuge. The system of fire information platform consists of three parts: the “manager interface”, “cloud database” and “fire information platform”. The results show that the fire information reported after the confirmation of the management personnel can improve the residents’ confidence in the source of the information. The test results in the experimental field show that the higher the integrity of fire information content and the more rigorous distribution process are, the more helpful it is to shorten the judgment time of pre-avoidance tragedy, and the visual fire information platform is helpful to the correct judgment of the refuge route. Adding a call button to the platform can also increase residents’ sense of security. Fire information integration platform can help elderly care institutions take immediate shelter action in case of fire.

Lightweight Steel Structures with high application targets, rapid construction and low cost. However, the influence of heat radiation on the internal temperature is very large, and in order to reduce the heat conduction caused by the sun, the user often attaches a flammable heat insulating material inside. In this study, the fire simulation software FDS was used to simulate the lightweight steel structure building fire, and the research on the thermal buoyancy, heat conduction, smoke distribution and building structure collapse limit of this type of building form was calculated. The research found that the steel thermal fluctuation and the fire flashover temperature of 600 °C were achieved after 520 seconds of fire. This study provides lightweight steel structure construction based on numerical calculation results. It is recommended to set the smoke exhaust window appropriately or use fireproof materials for interior decoration to reduce the heat accumulation inside the building to prolong the time of steel thermal fluctuation and make the lightweight steel structure It is not easy to flashover (backdraft) in the building, and the steel structure is not easy to collapse. It can improve the safety factor and make the life of fire rescue personnel more secure.
