본 논문에서는 로봇이나 감시 시스템에서 주로 쓰이고 있는 배경 모델링의 정확성을 지속 시키는 방법을 제안한다. 오브젝트를 추출하려면 정확한 배경 모델이 필요하다. 정확한 배경 모델을 유지하기 위해서는 전경의 정보가 배경 모델에 반영되면 안 된다. 본 논문에서는 오브젝트의 움직임을 기반으로 한 배경 무효화 기법을 사용 하여 전경이 배경 모델에 영향을 주는 것을 방지함으로써 정확한 배경 모델을 유지하는 방법을 제안한다.

In this study, we developed a rapid, sensitive and specific reverse-transcriptase loop-mediated isothermal amplification (RT-LAMP) assay for detection of swine influenza viruse (SIV) including major subtypes of swine influenza viruses H1N1, H1N2 and H3N2, and a novel subtype of influenza A virus that accidentally infected in pig population. The RT-LAMP was completed in 40 min at 58oC and the sensitivity of the RT-LAMP (1 copy/ L) was 10-fold higher than conventional reverse transcription-polymerase chain reaction (RT-PCR) (10 copy/ L) and the same to real time RT-PCR (1 copy/ L). Also, the result of the RT-LAMP can be confirmed without any detection system. Therefore, the RT-LAMP could be a alternative diagnostic method for SIV detection in national SIV monitoring system and clinical diagnostic laboratory in the future.

This study investigated the strength of concrete to improve construction material with polymer cement mortar. Some mixtures composed of Ethylrne Vinyl Acetate(EVA) and Acryl were studied. The two mixtures carried out the physical, mechanical test to determine its properties which a include : compressive, flexural, bond strength test. The test results show that the compressive strength was increased at long-term age when compared to early ages for increasing polymer contents. It was found that flexural strength and bond strength became larger as polymer to cement ratio became higher.

This study investigated the durability of the concrete to improve construction materials with polymer cement mortar. With the popularity of repair and rehabilitation material, some mixtures composed of Styrene-Butadiene Rubber (SBR) and Ethylen Vinyl Acetate (EVA) were studied. The two composite carried out the chemical resistance test. The results on the appears that the application of polymer cement is very beneficial in improving chemical resistance, specially EVA, which has been found to have a significant resistance to sulfate solution. This resistance is due to the filing and sealing effects of the impermeable polymer films formed. In conclusion, the addition of polymer to the cementitous materials improved the concrete properties and supplemented the defects in an efficient manner. Furthermore, it can be used as a repair and rehabilitation materials for reinforced concrete structures and as a resistance material in marine environment.

In this study, we developed a loop-mediated isothermal amplification (LAMP) with hydroxynaphtol blue dye (HNB) for rapid and direct visual detection of porcine circovirus 2 DNA with high sensitivity and specificity. The LAMP was completed in 40 min at 63oC, and the results of the LAMP can be confirmed by naked eye without any detection process. The sensitivity of the LAMP was 10-fold higher than that of the commercial PCR (cPCR) and real time PCR (rPCR) previously reported. In clinical application, the PCV2 detection rate of the LAMP was the same on porcine tissue samples (75.0%, 36/48) between porcine blood samples (75.0%, 39/52). The PCV2 detection rate (75.0%) of LAMP was higher than those of the cPCR and rPCR (67.3%, 35/52) in blood samples. In conclusion, the LAMP developed in the study could be an useful alternative method for the detection of PCV2 in the swine disease diagnostic laboratories.

In Marine environment reinforced concrete structures, such as intake structure, water and chloride ion penetrated into concrete through the cracks of concrete and its permeable property, cause the corrosion of reinforcing steel bar, which accelerates the expansive cracks and deterioration of concrete. The purpose of this paper is to evaluate on deterioration of durability concrete through instrumental analysis such as schmidt hammer and chloride content. Under the reclaimed marine environment, the main cause of deterioration of concrete structures is the steel corrosion due to the penetration of chlorides and the deterioration of outer concrete itself by chemical attack.
