In order to solve this sort of electrostatic failure in Display and Semiconductor process, Soft X-ray ionizer is mainly used. Soft X-ray Ionizer does not only generate electrical noise and minute particle but also is efficient to remove electrostatic as it has a wide range of ionization. There exist variable factors such as type of tungsten thickness deposited on target, Anode voltage etc., and it takes a lot of time and financial resource to find optimal performance by manufacturing with actual X-ray tube source. Here, MCNPX (Monte Carlo N-Particle Extended) is used for simulation to solve this kind of problem, and optimum efficiency of X-ray generation is anticipated. In this study, X-ray generation efficiency was compared according to target material thickness using MCNPX and actual X-ray tube source under the conditions that tube voltage is 5 keV, 10 keV, 15 keV and the target Material is Tungsten(W). At the result, In Tube voltage 5 keV and distance 100 mm, optimal target thickness is $0.05{\mu}m$ and fastest decay time appears + decay time 0.28 sec. - deacy time 0.30 sec. In Tube voltage 10keV and distance 100 mm, optimal target Thickness is $0.16{\mu}m$ and fastest decay time appears + decay time 0.13 sec. - deacy time 0.12 sec. In the tube voltage 15 keV and distance 100 mm, optimal target Thickness is $0.28{\mu}m$ and fastest decay time appears + decay time 0.04 sec. - deacy time 0.05 sec.

This research examines the interrelation of clothes, colors and sentiments based on clothes and colors that stimulate sentiment. This study provides data that is useful to color therapy by means of clothes as medium. The survey for this study targeted 200 Pusan National University students who analyzed the colors of association and clothes colors for nine positive vocabularies (passion, love, warmth, happiness, interest, softness, comfortable, freshness, and coolness) and six negative vocabularies (anger, fear, despair, nervous, gloomy, and loneliness). The data collection process used 120 standard colors as represented by Munsell's basic 10 colors (R, YR, Y, GY, G, BG, B, PB, P, RP) as chromatic colors classified into eleven tones of colors (V, S, B, P, VP, LGR, GR, L, DL, DP, DK) and achromatic colors divided into ten steps of brightness N1-N10. The results of the research are as follows. First, the warm class of colors were significant in the colors of association with positive sentiment and the cold class of colors were significant in the sentiment of refreshment and coolness. In addition, bright and clear colors (like V, S, VP, P) were associated with color tones. Second, the low bright achromatic colors were generally high for the colors of association with negative sentiment; in addition, the color of R, PB, P (as achromatic colors) were also significant. In addition, sober and dark tones (like GR, DL, DK, DP) were significant in color tones. Third, the interrelation between positive sentiment and clothes colors shows that colors of association were mainly used for upper garment colors. Similar colors against upper garments were used together for bottom garment achromatic colors and complementary colors; therefore, bottom garments play a subsidiary role in the concept of coordination with upper garments.

척수 전근내 구심신경의 특성을 알아보기 위하여 고양이에서 L7 척수 전근을 전기자극하여 유발되는 동맥혈압의 변동을 관찰하였다. morphine을 정맥내 혹은 직접 척수에 투여하여 그 효과를 관찰하였으며 척수에 부분적인 손상을 가하여 척수 전근의 구심정보가 척수의 어느 부위를 통하여 중추로 올라가 승압반응을 유발하는지를 결정하여 다음과 같은 결과를 얻었다. 1. 척수전근을 C-강도, 높은 빈도로 자극하면 현저한 승압반응을 유발하였으며 낮은 빈도로 자극할 때에는 피부 혹은 근육감각신경을 자극할 때 보이는 감압반응이 유발되지 않았다. 2. 경수부위를 절단하였을 경우 승압반응이 소실되어 승압반응이 전적으로 척수 상부구조를 통하여 일어남을 알 수 있었다. 3. 승압 반응의 척수내 상행경로는 척수의 dorsolateral funiculus에 양측성으로 존재하였다. 4. 정맥내로 주사한 morphine은 척수 전근내 구심섬유가 자극되어 유발되는 승압반응을 강화시켰으나 척수에 직접 투여한 morphine은 승압반응을 억제하였다. 이상의 결과로부터 척수 전근내에 존재하는 구심성 섬유들은 기능적으로 근육 감각신경 중에 승압반응을 유발하는 C-섬유와 유사한 성질을 갖는다고 사료된다.

The study is interested in the consumer's mixed choice of the internet and the offline stores. Therefore the purpose of study is to investigate if the clothing shopping orientation of consumers varies when they shop internet and offline, instead of classifying consumers into internet shoppers and offline shoppers. For the purpose, quantitative survey was carried out using 201 questionnaires from men and women in their twenties. The data were analyzed using factor analysis, Pearson's correlation analysis, Spearman's rank order correlation coefficient, t-test, and frequency analysis. The results are as following. First, the clothing shopping orientation structures of offline and internet stores were different each other. As the result of factor analysis, positive, brand oriented, economic, convenient conformity, convenient impulsive factors were extracted from offline store and rational, enjoying, goal oriented, conformity, brand oriented, convenient impulsive purchase factors were extracted from internet store respectively. Second, as the results of investigating the relationship between the clothing shopping orientation structures of offline and internet stores, positive(off)-enjoying(on), brand oriented(off)-brand oriented(on), convenient conformity(off)-conformity(on) had strong correlation s and the rest were peculiar to the each store type. Specifically, the goal oriented factor peculiar to the internet store was noticeable. Third, as the results of investigating the differences between clothing shopping orientation of offline and internet stores, the ranks of strong orientation dimension were different between two channels. As well, the mean differences were significant in goal oriented, conformity, brand oriented, and convenient impulsive purchase dimensions. This study has the significance that it investigated the variance of clothing shopping orientation according to the mixed selection trend of internet/offline.
