With the development of industry, fine dust is causing difficulties in various fields such as environment, health, and life, and a large amount of pollutants generated from human social activities are emerging as a serious environmental problem due to air pollution. Therefore, in this study, activated carbon was added to remove fine dust and volatile organic compounds by spinning cellulose acetate polymer fibers on a silicon support using the electrospinning method. By varying the activated carbon ratio and electrospinning time, the fine dust blocking effect and toluene adsorption performance were confirmed according to the activated carbon ratio and filter thickness. As a result, it was shown that the particles were effectively blocked with the increase in the electrospinning time due to the filter thickness increase. Adsorbed amount of toluene was increased with increase in activated carbon amount. Light transmittance was decrease with increase in electrospinning time, showing that there were light transmittance in filters electrospun for 20~30 minutes.

경찰의 임무 중에는 공공의 안녕과 질서유지가 있다. 공공의 장소에서 개인과 개인 간의 사소한 분쟁이 발생할 경우 당사자 중 한명이 경찰을 요청할 경우 이를 중재하기 위하여 경찰이 개입하게 된다. 교통수단 중의 하나인 택시이용과 관련하여 택시기사와 승객간의 요금분쟁이 특히 야간에 자주 발생하고 있다. 대부분 승객이 만취상태인데 술이 깨면 해결되나, 일부 택시기사들이 승객의 주취 상태를 악용하여 택시요금을 과다 청구하는 경우도 있어 경찰이 이를 실질적으로 해결할 수 있는 방안이 없는 실정이다. 이에 택시기사와 승객간의 택시요금 분쟁에 대한 특성과 경찰이 개입하여 처리하고 있는 보호조치 매뉴얼에 대한 문제점을 알아보고 개선사항을 제시하고자 한다. 또한 현대 IT기술이 발전함에 따라 택시이용과 관련하여 많은 IT서비스가 출시됨에 따라 이를 활용한 택시기사와 승객간의 요금분쟁에 있어서 경찰이 처리할 수 있는 가장 합리적인 조정방안과 택시이용과 관련하여 국민이 IT 서비스를 잘 활용할 수 있도록 지능형 개선모델을 제시하고자 한다. Among the duties of the police are maintaining public peace and order. In the event of minor disputes between individuals in public places, often the request is for a the police to intervene on the behalf of an individual. The police are expected to intervene to mediate minor disputes. In connection with disputes with taxi service, the most frequent call for police mediation is in fare disputes between taxi drivers and passengers. These requests are especially frequent at night, and involve passengers in a drunken state. The majority of these disputes could potentially be resolved, after the passenger has sobered up. However, some taxi drivers are reported to have exploited the drunken state of their passenger. They frequently over charged them, which is the cause of many disputes needing police mediation. Unfortunately, the Police have little to no way to actually resolve fare disputes. The solution that the police encourage is for the taxi driver and passenger to resolve the taxi fare dispute between themselves, often with the police mediating. We suggest that not only for the police to investigate the characteristics and problems of protection in the manual for handling fare disputes, but also improvements. In addition, As modern IT technology advances, many IT services is connected with the release of a taxi. Thus, it utilizes a Price disputes between passengers and taxi drivers that the police can handle the most reasonable adjustments. We suggest intelligent models to take advantage of improved IT service.

SMT장비는 전자부품을 흡착하여 PCB위에 정확히 실장을 하는 장비이다. 이때 부품의 정확한 실장을 위해 비전 카메라로 부품을 인식하여 보정치를 찾고, 이 보정치를 참조하여 PCB 상의 원하는 정확한 위치에 실장 할 수 있다. 일반적으로 비전 카메라로 부품을 인식하기 위해서 카메라 앞에 정지하여 비전검사를 한 후 실장 위치로 이동한다. 그러나 카메라 앞에서 정지하지 않고 그대로 통과하면서 비전 검사를 한다면 정지하는 시간을 단축함으로써 생산성이 향상 될 것이다. 본 논문에서는 카메라 앞에서 정지하지 않고 지나가면서 비전 검사를 할 때 겐트리 구동의 여러 경로 중 가장 빠른 시간에 이동할 수 있는 방법을 제시한다. 카메라 위치를 지나가는 방식에서 거리만 고려하는 것이 아니라 카메라 위치를 지나가는 속도까지 고려한 겐트리 구동 궤적에 대하여 연구하였고, 본 논문에서 제시하는 방식으로 움직이면 시간 이득이 약 5%의 향상되는 것으로 확인되었다. A SMT machine is used to place electronic components on a PCB precisely. To place it precisely, after a component inspection, it finds an offset value using a vision camera, and places the precise position on the PCB. In general, to inspect the components with a vision camera, the components stop in front of the camera for inspection, then move to the placement position. On the other hand, if they do not stop in front of a camera, the inspection time will be shortened and the productivity would be increased. In this thesis, when inspecting without stopping in front of a camera, the fastest way among various routes is described. For the gantry passing over a vision camera, both the distance and speed of a gantry moving trajectory were studied, and there was approximately 5% speed increment when using the method suggested in this thesis.

Recently, skyscraper building and apartment fires, which were rapidly spread out from a low floor to a rooftop, have become a frequent occurrence in mass media. This fire problems have a fatal disadvantage that the exterior wall finish of the building emits toxic gas in case of fire by using dry bit method or organic insulating material. Therefore, in order to remedy these problems, many exterior wall finishing construction methods have been proposed, but the current trend is to use existing construction methods due to problems such as economy, weight, and durability. On the other hand, in countries such as Germany and Japan, ceramic sidings are used as exterior finishing material for buildings, which is environmentally friendly, excellent natural beauty, long life, easy maintenance and high-quality exterior materials. However, those ceramic sidings have still the problems such as manufacturing cost and weight problem because of boosting the sintering temperature up to 1,350℃ or more. Also, conventional CRC, MgO, FRP sidings which are composed of pulp, glass fiber and organic materials, have been reports of deformation due to ultraviolet rays, discoloration, corrosion and scattering, surface rupture, lifting and peeling. Therefore, in this study as an alternative to solve this problem, halosite nano kaolin produced in Sancheong in Korea and frit flux were used to satisfy the required properties as ceramic siding using low temperature sintering (below 1,000°C) and lightweight materials such as pearlite. This study aims to design the optimal formulation and process of materials and to study the characteristics of nano-coated ceramic siding material development and to present relevant basic data. The findings show that ceramic siding for nanocoated building materials is excellent as a natural ceramic siding building material. The fire resistance of natural minerals and nano particle refining technology satisfy the bending strength of 80kgf / cm2, the volume ratio of 2.0 and the absorption rate of less than 10.0%.
