In this study an experiment was made using the function of computer simulation os to whether the phenomenon of optical illusion takes place also in clothing on the human body three-dimensional space through the case study of the Gestalt illusion of planar con-traction and expension by amodal completion in perceptual organization. One woman of latter 30s was selected as the experimental subject. She was made to wear the experimental clothing and then the frontal picture was projected of in the experimental clothing which was scanned into the com-puter. For the sake of the contractive experiment 5 stages were divided by 5-15cm the thick-nes of the black vertical line in the center of the upper garmet as the variable and for the sake of the expansive experiment the skirt length was set as the variable. It length measured 50-90cm which was divided by 10cm into 5 stages and simulated using the CAD. The basic design and the experimental de-sign were made one pair and the pictures totalled 20 pictures such as ten pictures save the human body for the estimation of the up-per garmet alone and ten pictures for the ob-servation of the effect on the human body. The extimating panel consisting of 20 panellers estimated contraction/expansion in the estimation of the upper garmet and the tall effect/the slim effect in the estimation of optical illusion as the estimating factors on the 9-point scale. All the date from experiment were analyzed by ANOVA(analysis of variance) and DUNCAN'S multiple range. As a result the experimental designs all showed a significant optical illusion in comparision with the basic design.

Even though modem ideal body type is rather tall and slim one, most of women don't coincide with it exactly. The objective of this research was to study the optical illusion effect of clothing design line so that average Korean women can approach the modern ideal body type. This research also tried to show the more scientific method to make stimulus by computer simulation and to present quantitative data. For the experiment, 9 design variables were selected from design principal book as follows : waistline level, skirt length, horizontal line emphasis, vertical line emphasis. princess line, vertical stripe, horizontal stripe, diagonal stripe. Each variable was divided into 4 levels so that 36 experimental designs were made. Visual stimuli which same model was wearing each design were recreated by the CAD system. These were given to evaluating panels through slide projecter. Then panels compared experimental design with basic design by 'tall effect' and 'slim effect', All the data from the experiment were analyszed by ANOVA and DUNCAN test for multiple comparison to study significance, direction(positive or negative), degree, proper extent of optical illusion effect. The result showed that some designs have optical illusion effect to make better look. In addition, it proved that the stronger design variable does not mean the more optical illusion effect and there was proper extent which produce the best illusion effect in each design variable.

The comic study which has been developed since the Eighteen century, is a subjective sense of the aesthetic concept and the aesthetics of comic is defined as a philosophy. The comic is opposite of the sublime or a superset of humor. This study investigated the aesthetics of comic and a popular graphic-print design on T-shirts. The research are the comic perspective on the aesthetic, expressive characteristics of the print design on T-shirt. And this study investigate literature and internet sites to extract data from the case studies. The aesthetic concept of the comic as an aesthetic category is defined as this study could inquire the comic cases expressed in t-shirts and graphic-prints on the emergence of historical change were discussed. Accordingly the three distinctions characterized as the parody, the optical illusion, the and the internet neologism. In conclusion, the aesthetic value graphic-prints on T-shirts appeared in the comic representation of the graphic-design of playfulness, extraordinariness, anti-nature, reflects popular culture is identified as.

This study was designed to investigate how the size perception of letters is influenced by its relation to the ground, visual angle, physical size, letter space and cognitive direction. As a stimulus, a word in the Numeral and Hangul respectively were used in Experiments I and II. Fifty four different configurations consisting of two grounds, three visual angles and nine physical sizes were used as test patterns in Experiment I, and one hundred and eight different configurations consisting of two ground, three directions, two letter spaces and nine physical sizes were used in Experiment II. Subjects were asked to make magnitude estimates for perceived size of test patterns in both Experiments I and II. The results imply that the ground and visual angle affected the perceived size of the Numeral as a focal figure. We found that in Experiment I, the perceived size of the focal letter was clearly underestimated when the rate of physical size was larger than the real size which was a hundred(as the size of standard stimulus), and it was overestimated when the rate of physical size was smaller than a hundred. It was found that the effect of Delboeuf illusion influenced the perceived size of letter. The result of Experiment II shows that the ground, physical size, letter space and the cognitive direction affected the perceived size of Hangul as a focal figure. These findings suggest that size illusion of letters is caused by the size relationship (contrast or assimilation) between a letter perceived as figure and its ground.

This paper considers the statistical characteristics on the air quality (PM10) of Korea collected hourly in 2011. PM10 in Korea exhibits very strong correlations even for higher lags, namely, long range dependence. It is power-law tailed in marginal distribution, and generalized Pareto distribution successfully captures the thicker tail than log-normal distribution. However, slowly decaying autocorrelations may confuse practitioners since a non-stationary model (such as changes in mean) can produce spurious long term correlations for finite samples. We conduct a statistical testing procedure to distinguish two models and argue that the high persistency can be explained by non-stationary changes in mean model rather than long range dependent time series models.

This study examined the structural elements of Korean-style houses (Hanok) and proposed formula accounting for their similar patterns and regular behavior. The design of modern apartment buildings adopts many aesthetic elements from Hanok but those are only for interior decoration. In this study, the projected Hanok eaves were examined in terms of the length of solar insolation. Leaning pillars toward the inside of the building were analyzed in detail not only for the front and back pillar, side pillar, but also the corner pillar. This study also suggested a design element from the Hanok structure, such as the elevated balcony, porch flooring, and inner garden in porch area. In addition, the new apartment plan improved air circulation, ventilation and natural lighting.

The purpose of this study is to survey fundamental limitations and problems of sports event hosting from the critical point of view and to set future-oriented perspective. The reason and legitimacy for hosting sports event have come from pragmatism based on ideological logic behind politics. Thus, the flow of advanced studies was mostly limited to the category of efficiency. However, there is fundamental limitation in sports even hosting in terms of its financial expectation and efficiency. Critical approach will contribute to minimizing side effects caused from blind acceptance through awakening dispassionate and realistic judgment. In addition, rational selection of sports even hosting can be achieved through interconnection of sports culturism's directivity as an advanced sense of sports culture, integrated perspective that penetrates problems of growth and distribution and local governance as apolitical philosophy, and of course, through concentration of energy.

Co/Pd and Co/Pt multilayered thin films for perpendicular magnetic recording media were fabricated by sput¬tering method and the effects of the sputtering pressure during the formation of Pd or Pt underlayers on the magnetization behavior and coercivity of the multilayers were investigated. It was found that the coercivity of Co/Pd multilayers was strongly dependent on the sputtering pressure of underlayer and could be enhanced to a large extent merely by increasing the sputtering pressure of underlayer, while in case of Co/Pt films, the degree of coercivity enhancement by controlling the sputtering pressure of underlayer was almost negligible. Coercivity variation of Co/Pd and Co/Pt multilayers with the underlayer material and deposition pressure of underlayer could be well explained in terms of the interface roughness of multilayer films induced by underlayer topology, which could also be correlated to the change of perpendicular anisotropy energy and magnetic reversal feature with the sputtering pressure of underlayer. Kerr rotation angle was hardly affected by the preparation conditions of underlayers.

The purpose of this study is to investigate the visual illusions and image of the combinated collars and sleeves which are combinated by the computer simulation. The detail object of this study as follows; 1) to know the visual illusions of the clothing as the collar and sleeves are combinated 2) to constract the clothing image using sementic differential scales 3) to know the differet image of the clothing as the collars and sleeves are combinted 4) to know the interaction effect of the collars and sleeves of the clothing The detail method of this study is as follows; In the first experiment, there are two groups; the first 8 groups are the combination of the same collar and the different sleeves. The second 8 groups are the combination of the same sleeve and the different collars. The second experiment has done for the 32 clothings which are the combination of the 8 collars and 4 sleeves. For the 14 clothing the image has tested by 13 semantic differential bi- polar scale. The subjects were 50 female students majoring in clothing and textile. The data analyzed by Kendall cofficient of concodance, Factor analysis, Anova and scheffe's test. Briefly the image of the clothing is much influenced by the varing of the collar than that of the sleeve. Thus, we also can conclude that the recognition of the clothing are much more dependent on the collar than sleeve.

The deposition rate and surface morphology of Al films deposited by MOCVD have been studied on the $SiO_{2}$ and TiN(60nm/Si) substrates. A1 films were deposited with the pyrolysis of dimethylethylamine alane(DMEAA). When A1 was deposited on Ti& substrate without carrier gas, Al deposition rate increased with H\ulcorner pre- treatment. The $H_2$ gas enhances the CVD reaction at the substrate surface. When Al was deposited on $SiO_{2}$ substrate, $H_2$ plasma pretreatment reduced Al incubation time and made a dense Al film compared with Ar plasma pre- treatment or no pretreatment.
