  • The characteristics of <112> orientation were studied for the $TiO_2$thin films, which were prepared on the glass by CVD (chemical vapor deposition) at various substrate temperatures. It was confirmed that $TiO_2$ films exhibited <112>-preferred orientation in a specific temperature range. Although $TiO_2$polycrystalline film grown deposited at relatively low temperature showed the growth of random directions, the <112>-preferred orientation was gradually developed with increasing deposition temperature. According to exhibit higher degree of <112>-preferred orientation, $TiO_2$thin film showed porous surface morphology, well-developed columnar structure, and deeper voids resulted from non-aggregation of columns were observed. In addition, transmittance was enhanced. Therefore, the growth of $TiO_2$with <112>-preferred orientation is suitable for glass coating because of predominance of photocatalytic efficiency and transmittance.

  • The Purpose of this study is to search for ways to improve the police-related emergency reporting service through the analysis of its actual condition - focusing 112 emergency reporting & 122 emergency reporting. For this purpose, the main data related to police-related emergency reporting required for inspection of the administration conducted by the National Assembly in 2013 is utilized. The actual condition of the police-related emergency reporting service is examined in 3 aspects - the number of reported cases by reporting type, the number of police response, and the average arrival time. The principal analysis results of the actual condition revealed that 112 emergency reporting is increasing and 122 emergency reporting oscillates between increases and decreases in the total number of reported cases, the number of non-emergency reporting is increasing in both 112 and 122 reported cases, the number of prank call is high in 122 reported cases, the rate of other agency transmit($122{\rightarrow}112$) is higher than 12% in 122 reported cases, and the number of police response and the average arrival time are decreasing in 112 reported cases. To improve the police-related emergency reporting, based on the above actual condition, the followings are required: to operate dualistic police-related response; to publicize a police-related reporting service; to take stern measures against false report; to make continuous improvement of the police-related emergency reporting system.
