최근 들어 코인을 넣고 자신이 원하는 시간만큼 효율적인 세차를 할 수 있는 셀프세차장 이 점차 확대되고 있는 추세에 있다. 시간과 비용 절감효과가 있는 셀프세차 시스템은 이용자가 직접 코인을 넣고 서비스를 제공받는 다는 점에서 분명히 자판기의 한 분야로 볼 수가 있다. 그런데 최근 이러한 셀프세차 시스템이외에도 스팀을 이용해 세차를 할 수 있는 스팀세차자판기 시스템이 등장해 큰 관심을 끌고 있다. 이 스팀 세차는 물을 주로 이용하는 셀프 세차보다 공간활용 측면, 경제성 등에 있어 장점을 가지고 있어 제대로 소비자 인식만 전재된다면 큰 인기몰이를 할 수 있을 것으로 기대되고 있다. 국내 최초로 스팀세차 자판기를 개발하고 셀프 세차 시장의 돌풍 몰이를 준비 중인 지산테크의 사업행보를 통해 앞으로의 시장 가능성을 살펴보는 시간을 마련했다.

According to development of weather radar, researches about observation, analysis or forecast of weather phenomena such as tornado, flash-flood etc. were encouraged by reducing frequency interferences, transmission noises, attenuations of radar signal. In contrast, there is a growing interest in the visualization and expression methods for weather radar data but weather radar manufacturers or the organs of government for weather are just busy interpreting expressed weather images projected on GIS. We propose an effective high definition weather radar information visualization method able to apply various GIS platforms to observe and take actions against rapid local weather changes effectively. In this paper, first we change information acquired from weather radar to raster or vector type high definition data structures using specific algorithms. And then, we quadrate our processed raster/vector type weather data with various GIS platforms accurately to make observers can recognize and check weather situations over exact geographical positions and elevations intuitively. Experimental results verify that our method make observers can recognize and analyze weather changes, tornados, local downpours or flash floods accurately by analyzing high definition weather radar data combined with GIS platform including detailed target locations and elevations.

The objective of this study was to develop an advanced pump technology using tornado and axial pumping principles without priming water. The developed rotor type slurry pump consisted of an electric motor, driving shaft and coupling, a rotor, an impeller, suction and discharge pipes. For the clean water test, the experimental results are presented for the discharge flowrate, electric power input and vacuum pressure with the rotor design parameters as a function of the motor rpm. The slurry discharge characteristics with the solid concentration of the cement slurry was performed. As the rotor diameter and height increase, the discharge flowrate and electric power input increase while the vacuum pressure in the suction pipe decreases. The rotor thickness had no significant effect on the discharge flowrate and electric power input. Slurries with more than 18 % solid concentration, which is the development factor, can be pumped.

This research deals, The characteristics of mechanics and behavior of the tube structural systems, It has been investigated and considered conventional theory and case models, It has shown the suitability, The best location, And optimal shape of the unit module system, Considered variables materials of stiffness increase and decrease in hybrid tube structural systems this study carried out adapting analysis of statistical concepts. In a concrete way, This study exams the effect of reducing horizontal displacement and the shear lag phenomenon, Also, The purpose of this study is to utilize the basic data on the design and study of future high-rise hybrid structural system using this research. As a result, The framed- tube structural system does not effectively cope with horizontal behavior of high-rise buildings, The results of using varying material tested resistance factors and lateral loads in hybrid tube structural system, When each material is compared Bracing material is identified as a key factor in lateral behavior. In a ratio of material quantity framed-tube structural system, The level of sensitivity affecting the horizontal displacement is greater then the beam's column, In case of braced tube structural system, Braced appeared to be most sensitive in comparison of material quantity ratio in columns and beams.

As the frequency and intensity of catastrophic disasters increase, there is widespread public sentiment that government capacity for disaster response and recovery is fundamentally limited, and that the involvement of civil society and the private sector is ever more vital. That is, in order to strengthen national disaster response capacity, governments need to build disaster systems that are more participatory and function through the channels of civil society, rather than continuing themselves to bear sole responsibility for these "wicked problems." With the advancement of smart mobile technology and social media, government and society as a whole have been called upon to apply these new information and communication technologies to address the current shortcomings of government-led disaster management. As illustrated in such catastrophic disasters as the 2011 Tohoku earthquake and tsunami in Japan, the 2010 Haitian earthquake, and Hurricane Katrina in the United States in 2005, the realization of participatory potential of smart technologies for better disaster response has enabled citizen participation via new smart technologies during disasters and resulted in positive impact on the management of such disasters. In this context, this study focuses on the South Korean context, and aims to analyze Korean government officials' readiness for public participation using smart technologies. On this basis, it aims to offer policy suggestions aimed at promoting smart technology-enabled citizen participation. For this purpose, it proposes a particular model, termed SMART (System, Motivation, Ability, Response, and Technology).
