In this paper, a depth image up-sampling method is put forward by using pixel classifying and jointed bilateral filtering. By analyzing the edge maps originated from the high-resolution color image and low-resolution depth map respectively, pixels in up-sampled depth maps can be classified into four categories: edge points, edge-neighbor points, texture points and smooth points. First, joint bilateral up-sampling (JBU) method is used to generate an initial up-sampling depth image. Then, for each pixel category, different refinement methods are employed to modify the initial up-sampling depth image. Experimental results show that the proposed algorithm can reduce the blurring artifact with lower bad pixel rate (BPR).

In order to reduce the length of off-gauge at FGC(Flying gauge change) point, We adopted dynamic set up in No. 4 cold rolling mill. The conventional set-up of FGC(Flying gauge change) was calculated on the basis of preset values in the process control computer, so the difference between actual strip thickness and preset thickness cause long off-gauge. The dynamic SET-UP control was calculated on the basis of actual strip thickness of FGC(Flying gauge change) point from X-ray gauge of mill entry and No.i stand. We applied dynamic SET-UP control in September last year. Compare to the previous result, the length of off-gauge is reduced by about 36%.

From this first studies, We have investigated the latch-up characteristics of various CMOS well structures possible with high energy ion implantation processes. In this study, we also investigated those of STI(Shallow Trench Isolation} structures with varing n+/p+ spacing and the depth of trench. STI structure is formed by T-SUPREM4 process simulator, and then latch-up simulations for each case were performed by MEDICI device simulator for latch-up immunity improvement. STI is very effective to preventing the degradation of latch-up characteristics as the n+/p+ spacing is reduced. These studies will allow us to evaluate each technology and suggest guidelines for the optimization of latch-up susceptibility.

The focus of this study is on the diffusion and aspects of Yoenji make-up in China. The diffusion of Yoenji make-up into China was achieved by Zhuang-Kun's departure for the West of China, after Emperor Moo of Han Dynasty defeated the Huns (B.C. 121). The Yoenji make-up is basically used as a unique sign and from the result of excessive development from the facial beauty point in accordance with luxurious Court culture and opening door of culture. It can diversely express kinds, names, ways, types and patterns, places and bodily parts, the colors of materials for use, and time zones of a make-up.

The purpose of this study was to investigate the relationships among clothing image, make-up image, and hair image. The Data were collected from 306 women living in Gyeongnam province in June, 2009. Statistical analysis used in this study were frequency, F-test, t-test, Duncan test, factor analysis, Cronbach's ${\alpha}$, correlation coefficient, and multiple regression. The results of this study were as follows.: Three factors of clothing image were titled as elegance, youth, and visibility. Three factors of make-up image were titled as modern, romanticism, and mediocrity. Four factors of hair image were titled as attraction, individuality, gentleness, and cuteness. The clothing image, make-up image, and hair image according to the demographic characteristic of women showed significant difference. The clothing image resulted in correlation with the make-up image and hair image. The clothing image had a influence on the make-up image and hair image.

Extraction and Clean-up procedures coupled with quantitation by high performance liquid chromatography(HPLC) was evaluated for the detection of 4 aflatoxins, B1, B2, G1 and G2, in peanut butter. The Sep-pak clean-up method showed poorer separation and repeatability than did the modified DeVries' and an immunoaffinity column clean-up methods. No significant difference of detected aflatoxins between the affinity column clean-up and modified DeVries' method. The coefficients of variation for the 4 aflatoxins were ranging from 6.3∼32.3 by the modified DeVries' method and 5.3∼9.8 by the affinity column clean-up.

The distortion correction system of Head up display that is installed in vehicle has been studied both experimentally and theoretically for the removal of the optical lens distortion. A new adaptive correction method is having a decisive effect on correction in the optical lens distortion of Head up display. This adaptive correction system removes various distortion that has occurred because of the design tolerances of Head up display and the assemble tolerances into vehicle. It is especially efficient in removal of a barrel distortion and pin cushion of Head up display.

The performing art represents joy, anger, sorrow and pleasure through acting and dance, and is told to be a composite art represented by make-up, setting, costume and props. Therefore, it can be said that make-up is an important medium of stage art. Make-up in stage art is a kind of communication with audiences through understanding personalities of characters as demanded by scenarios. Due to the creative stage make-up which meets the character in the play relevant to these contents of the play, the conceptual study on stage make-up design for visual expression coincide with the intended character is needed. In this study, I investigate theoretical, universal, and psychological personality types by analyzing basic appearance features based on the physiognomy(face-reading) related from the psychological theories. And visualized through illustration according to personality types to apply for the characters in the play.

The Start-up transformers or on-site stand-by transformers are installed for the start-up and shut-down of generator and emergency status in unclear power plant. The on-site power supply configuration using these transformers must be detemined by considering configuration requirements, site characteristics, reliability and availability severely because it is remarkably important for safety and benefit of plant. The start-up or stand-by power supply configuration has been determined considering only safety requirements and construction cost up to now in Korea. I study various reliability estimating methods for the prediction of availability, and estimate the unavailability for the start-up power supply system of two 1,000㎿ unclear power plants. I also detemine the reliability and unavailability and unavailavility of equipment, system and configuration using FTA method.

The purpose of this study is to analyze KAIST students' perceptions of intellectual property and start-ups and educational needs. In this study, literature research, interviews, and surveys were conducted, and 5 students participated in the interview, and 202 students participated in the survey. Students had similar perceptions of intellectual property and start-up education. KAIST students had very little experience in intellectual property and start-up-related education in middle, high schools and universities. In particular, most students highly recognized the importance of intellectual property and start-up education, but recognized that the importance was low in their career path. Therefore, students were also less willing to participate in intellectual property and start-up-related education in the future. Students demanded the highest education on 'patent management' in intellectual property-related competencies, and the highest demand for 'start-up idea derivation ability' in start-up-related competencies.
