This research aims to analyze changes in anion according to locations through changes in the measuring point centering on a single tree. The subject tree was the Zelkova serrata which is most widely used as a landscape tree, and the measurement was conducted for a total of 3 days with summer solstice as the basic date. In consideration of the solar altitude and the location of the Zelkova serrata, a total of 4 measurement points - $T_a$ at the opposite direction of the shadow, $T_b$ in the center of the tree $T_c$ in the center of the shadow, and $T_d$ at the end of the shadow - were established. The mean temperature of the measurement days was the highest at $T_a$ with $28.4^{\circ}C$ and was the lowest at $T_c$, in the center of the shadow with $27.9^{\circ}C$. The relative humidity was the lowest with 42.5% at $T_a$ where the temperature was the highest. The amount of insolation was the highest at $T_a$ with $1,024.6W/m^2$, followed by $T_d(701.48W/m^2$), $T_c$($215.63W/m^2$), and $T_b(227.75W/m^2)$, and the anion was the highest at $T_a$ with $654ea/cm^3$, followed by $T_d$, $T_c$, and $T_b$, with $639.4ea/cm^3$, $615.3ea/cm^3$, $612.3ea/cm^3$, respectively. The results of the correlation analysis proved that anion correlated with the temperature, the amount of insolation, and the relative humidity on the significant level. Of these, the temperature and the amount of insolation had the positive correlation with the correlation coefficients of .687 and .332, respectively, and the significance probability of .000, and .037, respectively. The relative humidity was found to have negative correlation. Its correlation coefficient and the significance probability were -.557, and .000, respectively.

This study analyzed weather characteristics for each biotope type and influential factors on outdoor temperature in the summer when thermal contamination is at its worst targeting Daedoek-gu, and suggested a management plan in thermal comfort aspect by using a bioclimatic chart. Impermeable area ratio for each biotope type was shown in orders of industrial area biotope(94.80%)>commercial area biotope(92.20%)>low floor residential area biotope (85.75%)>high floor residential area biotope(76.02%)>river biotope(2.35%)>forest biotope(0%). Meteorological element analysis was divided into daily maximum and daily minimum and conducted, and outdoor temperature, humidity, wind speed, globe temperature, and surface temperature were measured. Outdoor temperature at the daily maximum temperature was shown in orders of industrial area biotope(36.3℃)>commercial area biotope(35.5℃)>high and low floor residential area biotope(34.8℃)>river biotope(33.9 ℃)>forest biotope(30.4℃). Low humidity was created at high temperature region and high humidity was created at low temperature region, there was no special tendency in wind speed but it contributed to creation of outdoor temperature, and surface temperature and globe temperature were measured as same tendency as outdoor temperature. Outdoor temperature at the daily minimum temperature was shown in orders of commercial area biotope(27.5℃)>industrial area and low floor residential area biotope(26.9℃)>high floor residential area biotope(26.5℃)>river biotope(26.6℃)>forest biotope(26.4℃), humidity was over 80%, and globe temperature was low temperature region with lowest value at forest biotope(26.8℃) and river biotope(26.7℃) that have strong wind speed. As a result of understanding the level of affecting creation of outdoor temperature for each land cover type, impermeable cover area showed positive correlation(correlation coefficient of 0.608) for increase of outdoor temperature, and tree planting area had negative correlation(correlation coefficient of -0.694). It was analyzed surface temperature (correlation coefficient of 0.821) and globe temperature(correlation coefficient of 0.790) had high interrelationship with change in outdoor temperature. Based on this, this study suggested expansion of green and water permeable cover, inflow of air current, and application of a planting method that considered wind corridor as a means to enhance comfort for each biotope type.

Presently, The Regular Block System(Automatic, Interlocking block system) is usually used during the operation of block section. However, In case that the regular block system fails because of the failure of the fixed signals and block equipment or in case of the unexpected emergent situation which should drive on the single-track due to the accidents in the double-track section or the repair work of the one-track, the Substitute Block System to make use of the driving permission license(mapping ticket, mapping paper) is used. In case of the operation of the opposite line and the temporary one-track, the safety gets worse and the SBS may cause the fatal accidents such as a head-on & a rear-end collision. Also, the unmanned railroad stations has recently increased owing to the effective operation of the stations, for it is difficult to execute the SBS in their absence. As a result, the increase of the operation time made the train delayed. Being on the rise of these problems, in this study, we analyzed the problems and difficulties of the SBS on the single line which is lacking stability and safety and on the sections combined between maned and unmaned railroad stations. And we proposed the method to improve the existing drive permission license used for 50 years into the brand-new one with state-of-the art technology and scientific way. In the era of the 21th century, Carrying out the new SBS equipped with stability and safety, we will contribute to the effective operation of trains and the satisfaction of our customers in the future.
