피인쇄물 위에 비화선부를 잉크가 통과하지 않도록 피막으로 씌운 스크린 망사를 놓고, 그 위에 넣은 잉크를 스퀴지로 강제적으로 눌러서 인쇄하는 스크린인쇄는 처음에 망사 재료에 비단을 이용했기 때문에 실크스크린인쇄라고 불리고 있다.

In this study, we analyzed and compared the constituents of Southern ecotype garlic cultivars, Namdo and Daeseo garlic, cultivated in volcanic and non-volcanic ash soil in Jeju Island and compared the soil properties in these regions. The volcanic ash soil in which Namdo garlic grew had higher electrical conductivity and more available sulfur, whereas the volcanic ash soil in which Daeseo garlic was cultivated had a higher amount of organic matter and total nitrogen. Also, non-volcanic ash soil in which Namdo garlic was cultivated had higher levels of available phosphorous. Namdo garlic cultivated in volcanic ash soil had high levels of total soluble solids and a high allicin content and Daeseo garlic exhibited a higher reducing sugar content. Furthermore, amongst the macroelements found in garlic grown on Jeju Island, potassium was highest, followed by sulfur, magnesium, calcium, and sodium. Iron was the most abundant micronutrient, followed by zinc, manganese, and copper. These results will be of interest to farmers aiming to cultivate high-quality garlic.

This paper describes the color comparison analysis of flame in each standard color model in order to propose the optimal color model for image processing based flame detection algorithm. Histogram intersection values were used to analyze the separation characteristics between color of flame and color of non-flame in each standard color model which are RGB, YCbCr, CIE Lab, HSV. Histogram intersection value in each color model and components is evaluated for objective comparison. The analyzed result shows that YCbCr color model is the most suitable for flame detection by average HI value of 0.0575. Among the 12 components of standard color models, each Cb, R, Cr component has respectively HI value of 0.0433, 0.0526, 0.0567 and they have shown the best flame separation characteristics.

There are more than 2,900 different species of termites in the world, and just there are 23 species in Japan. They caused more severe infestation compared with Korea. When a structure has become infested with termites, it is important that appropriate action must be taken: the chemical pest control (fumigation, soil termiticide treatment, bait system etc.) or the non-chemical pest control (low oxygen treatment, carbon dioxide treatment, high/low temperature treatment etc.). Especially, there were attempts to make practical protocol of various alternatives since the fumigant(methyl bromide) had been phased out in 2005 in Japan, and practically non-chemical methods would be effective alternatives for some cases, where the scale of infestation is small and limited and when long treatment is possible. But most of all, it is important that the process of pest control is made according to each species of termites with consideration for different characteristics of termites.

This study evaluated thermal image real-time estimation and fire alarm using by a CCD camera, which has been a seamless feature-point analysis method, according to the angle and position and image fusion by a vector coordinate point set-up of equal shape. The system has higher accuracy, fixing data value of temperature sensing and fire image of 0~255, and sensor output-value of 0~5,000. The operation time of a flame specimen within 500 m, 1000 m, and 1500 m from the test report specimen took 7 s, 26 s, and 62 s, respectively, and image creation was proven. A diagnosis of fire accident was designated to 3 steps: Caution/Alarm/Fire. Therefore, a series of process and the transmission of SNS were identified. A light bulb and fluorescent bulb were also tested for a false alarm test, but no false alarm occurred. The possibility that an unwanted alarm will be reduced was verified through a forecast of the fire progress or real-time estimation of a thermal image by the change in the image of a time-based flame and an analysis of the diffusion velocity.
