  • This paper describes a study to determine proper escape way interval for the design phase of single bored double track tunnel. Among many methods which determine escape way interval, we choose a QRA(Quantitative Risk Analysis) method. But a different method must be chosen differ from other country because of special design situation of Korea. So, it is necessary to develop a method which considers a special design condition of Korea. Because fire accidents of railway tunnel are a rare event, simulated situation can be produced by CFD simulation and evacuation analysis simulation. However, it is generally difficult to estimate of fatalities from these methods, so a concept of FED is introduced to estimate of fatalities. Quantification process provides effective results for practical design stage and the result were employed in design.

  • Based on the theory of use and satisfaction, this study investigated the strength of TikTok usage motives (entertainment, information-seeking, interaction, self-expression, and escape) and the effect of each motive on users' adherence (frequency of use, time of use). investigated. After conducting a survey on TikTok Chinese users and removing insincere answers, 101 survey results were analyzed. The analysis results are as follows: First, the intensity of motivation for using TikTok was in the following order: entertainment-seeking, information-seeking, interaction, self-expression, and escape. Among them, the motives of pursuit of entertainment and escape were higher in females than in males. And the motives of pursuit of entertainment and escape were higher in the case of women than in the case of men. Second, as a result of analyzing the effect on user adhesion, the influence of the users' entertainment pursuit motive, interaction motive, and escape motive was significant for the frequency of use, and the influence of interaction was high. Third, the influence of entertainment-seeking motives and escape motives was found to be significant for use time. This means that users often use TikTok for entertainment, interaction, and escapism, and longer TikTok usage time for entertainment or escapism.

  • The neutralization epitopes of the outer capsid protein VP4 of a porcine rotavirus, Gottfried strain, were studied using neutralizing monocolonal antibodies(N-MAbs). Eight N-MAbs which are specific for the VP4 of Gottfried strain were used for analyzing the antigenic sites of VP4. Three different approaches were used for this analysis; i)testing the serological reactivity of each N-MAb against different G and P types of human and animal rotavirusese ii) analyzing N-MAb-resistant viral escape mutants and iii) performing nucleotide sequence analysis of the VP4 gene of each N-MAb-resistant viral escape mutant. From experimental results, at least four antigenic sites(I, II, III, and IV) were identified. Antigenic site I recognized by N-MAbs 24B9, 23G10, and 26A2 was separated from antigenic site II recognized by N-MAbs 30H5, 32B3, and 29B3. However, these antigenic sites were overlapped with antigenic site III recognized by N-MAb 21A1. The other antigenic site IV recognized by N-MAb 16D2 was separated from antigenic sites I, II, and III.

  • The purpose of this study is to propose the angle-limit of the escape ramp by analyzing the frog behavior characteristics according to the inclination angle of the waterway escape ramp installed in the concrete U-bench plume pipe channel. Forthe experiment, an escape test device was manufactured with the same shape and number of materials applied in the field. And Rana coreana living in paddy wetlands were sel selected. The main behaviors of frogs on the slope were 'jumping', 'crawling' and 'slipping', and afterrecording the behavioralresults according to the inclination angle, statistical analysis was conducted using the chi-square test method. As a result of the analysis, there was no statistically significant difference between 30° and 40°. This result is an evidence for expanding the standard of inclination angle 30° suggested in the 'Guidelines for Installation and Management of Ecological Pathways' to a maximum of 40°. However, further research is required in that the escape ramp targets not only Korean frogs but also various small wild animals. However, considering that various wild animals are affected by artificial canals, additional studies using various target wild animals are needed.

  • This study examines the damage to the submarine's escape trunk hatch spring through microstructure analysis. The cause of the escape trunk's damage during the submarine's construction and its improvement measures were reviewed. To determine the cause of breakage of the escape trunk spring, samples were taken from the damaged product and analyzed for chemical composition, hardness, and microstructure. In particular, the breakage part of the spring was analyzed in-depth by using a scanning electron microscope to determine the cause of corrosion destruction. Finally, a spring shape design method was proposed through the investigation of the cause of spring breakage. In addition, a newly improved spring was produced by applying a nylon coating with excellent corrosion resistance and abrasion resistance. Applying to an actual submarine trunk hatch revealed that the coating peeling phenomenon due to the contact between the springs is significantly improved when the hatch is opened or closed compared to the existing products.

  • The objective of this study is to verify the safety in case of fire and change of residential environment for different wall construction approaches in a stairways apartment house. In order to confirm that case_1, which is current case that most of wall is opened and the case 2, which upper part of wall is limitedly opened are compared and analyzed based on simulations of fire, escape and natural ventilation performance. The analysis reveals that possible escape time for case 1 was more than 600 seconds and for case 2 was 195 seconds. Since the escape times for both cases were over 128 seconds, it would be reasonable to assume that every resident would escape. The simulation results on natural ventilation performance shows the air change per hour of case 1 and case 2 were .19n/h and .16n/h and there was 1.2 times difference. However, the difference was too insignificant and it could be seen as that different approaches on wall construction would not significantly influence on natural ventilation performance.
