The screen-printing method is the most mature solar cell fabrication technology, which has the advantage of being faster and simpler process than other printing technology. A front metallization printed through screen printing influences the efficiency and manufacturing cost of solar cell. Recent technology development of crystalline silicon solar cell is proceeding to reduce the manufacturing cost while improving the efficiency. Therefore, screen printing requires process development to reduce a line width of an electrode and decrease shading area. In this paper, we will discuss the development trend and prospects of screen-printing metallization using metal paste, which is currently used in manufacturing commercial crystalline silicon solar cells.

A severely vertical resorbed ridge is a significant challenge in implant dentistry. To solve this problem, several augmentation techniques, such as guided bone regeneration (GBR), onlay bone grafts, distraction osteogenesis, and ridge splitting techniques, have been proposed and used for several years. Among these methods, vertical ridge augmentation using guided bone regeneration aims to build space and guide osteoblasts to this space to promote osteogenesis. The aim of guided bone regeneration is to maintain and stabilize the space and block the proliferation of adjacent soft tissue. In our hospital, we encountered a case of a woman in her forties with an atrophied mandible, who underwent implant surgery in the right mandible. Titanium reinforced Gore-Tex (TRG) was used to augment the mandible and titanium mesh was used in the left mandible. Favorable results were obtained. This report compares the two methods and reviews the relevant literature.

In this study, the risk of red water and turbid water occurrence was analyzed by classifying it into detachment risk and deposition risk. First, risk factors for red water and turbid water were determined, and hydraulic analysis was conducted considering seasonal water consumption. The applied area was Cheongju City, and the risk analysis was conducted across 13 areas, and the areas with high deposition risk and high detachment risk were selected. The high risk of both detachment and deposition can be judged as an area with a very high probability of causing water quality problems. The areas with the highest deposition risk and detachment risk are the old towns of Nae deok1-dong and Yul1yang-dong, which are the oldest areas in Cheongju City with an age of more than 30 service years of pipe installation. By analyzing the risk of deposition and detachment, it will be possible to strengthen the maintenance function of the water supply network to provide the safe water to citizens and increase their confidence for tap water.

This study tried to understand influence of water fluoridation program on oral health status and get the basic data of water fluoridation program in the future. Sangdang-gu in Cheongju City, fluoridated community and Manan-gu in Anyang City, non-fluoridated community were the surveyed area of the study. And from July 3, 2003 to July 22, 2003, using questionnaire, we surveyed opinions of parents of the fifth and sixth grade students of C elementary school in Sangdang-gu, Cheongju City and A elementary school in Manan-gu, Anyang City about water fluoridation program, and made an oral examination on the fifth and sixth grade students. The results are as follows : 1. DMFT index was lower for Cheongju, fluoridated community with Cheongju 1.69, Anyang 2.11(P = .010). 2. DMFT rate was lower for Cheongju, fluoridated community with Cheongju 6.72%, Anyang 7.94%. 3. Health level of the first molar was higher for Cheongju, fluoridated community with Cheongju 95.54%, Anyang 94.10%(P = .002). This study intends to understand the effects of fluoridation program on oral status by analyzing the effects of water fluoridation program and present basic materials for improving oral health. Improving national oral health is thought to be associated with expense retrenchment of oral health insurance financial. So it may need to extend using tap water to all the area of the country and additionally establish confidence through an active public relations and education of water fluoridation program.

The characteristics of six precipitation systems occurred around Cheongju in 2002 are analyzed after the convective/stratiform radar echo classification using radar reflectivity from the Meteorological Research Institute"s X-band Doppler weather radar. The Biggerstaff and Listemaa (2000) algorithm is applied for the classification and reveals a physical characteristics of the convective and stratiform rain diagnosed from the three-dimensional structure of the radar reflectivity. The area satisfying the vertical profile of radar reflectivity is well classified, while the area near the radar site and the topography-shielded area show a mis-classification. The seasonal characteristics of the precipitation system are also analyzed using the contoured frequency by altitude diagrams (CFADs). The heights of maximum reflectivity are 4 km and 5.5 km in spring and summer, respectively, and the vertical gradient of radar reflectivity from 1.5 km to the melting layer in spring is larger than in summer.

Soil erosion and sediment delivery ratio(SDR) were estimated by using HSPF model in 3 tributaries of upper stream of Geum river-basin. Meteorological data and other input data were constructed from 2006 to 2011 year by the HSPF model. Flow and suspended solid results were relatively matched with the measurement data through the calibration and validation of the model. Soil erosion was proportional to the amount of rainfall and the area of watershed based on the results of model calibration and validation. SDR in Moojunamdea stream was the highest and one in Cho stream was the lowest. This was effected by the geographical characteristic. SDR was 17.6% Moojunamdea stream, 9.1% Cho stream and 13.2 % Bocheong stream. As the SDR was effected by watershed area and shape factor in this study area.
