The purpose of this study was to identify the physical characteristics of early adolescent girls by age. A total of 529 girls aged between 10 and 14 were measured and data were collected from 42 anthropometric and 41 photographic measurements per a person. SAS 8.1 was used in data analysis including means, standard deviations, t-test, Duncan test and frequency analysis. The results of this study are as follows. Most items related to height and length increased significantly at the age of $10\sim11$ and the growth slowed down at the age of $13\sim14$. As for items related to circumference, the growth rate was high at the age of $11\sim12$, and gradually slowed down afterward. Out of circumference items, hip circumference showed the highest growth rate. As for items related to thickness and width, thickness-related items grew quickly at the age of $10\sim12$, and among which bust thickness showed the highest growth rate. As for drop, the difference between hip circumference and waist circumference was most remarkable, but the difference between hip circumference and bust circumference was not large. The largest number of subjects had their menarche during the age of $11\sim12$ and, after menarche, their horizontal growth became active.

The purpose of this study is to comprehend western style in fashion and to contemplate the hybrid tendency reflected on western style, thereby to analyze the aesthetic characteristics of the hybrid tendency of western style. For such purposes, this study first examines western style historically, in order to analyze hybrid tendency reflected on western style, and conduct a case study by analyzing photographic materials of pr t- -porter collection since 1980s. The result of this study is as follows: the hybrid tendency reflected on western style are modification and fusion of regional culture, adaptation and composition of subcultures, and appropriation of sexual minority culture. (1) Modification and fusion of regional culture is expressed in ethnic items and patterns of embroidery, mixing Mexican and Spanish, American Indian and American cultural references. (2) Adaptation and composition of subcultures emphasize traditional or vintage western style by mixing characteristics of western and other subcultures. (3) Appropriation of sexual minority culture is expressed in rhinestone chaps and fetish corset, glitter rodeo suit, reminiscent of drag or queer cultural references. The result of this study will provide basis which can be utilized in the development and educational background of fashion design.

The purpose of this study is to investigate the characteristics of electroencephalogram (EEG) during emotional occurrence of likes and dislikes in humans subjected to visual stimuli. Fifteen healthy male subjects participated in the study. Portrayals of females and cars on a visual screen, one photographic display at a time. were used as the stimulus. The subjects, with their EEGs concomitantly monitored, were asked to record their likes and dislikes for each portrayal of a total of 50 sequential displays. The results indicated that beta ($\beta$)=wave was more prevalent with dislikes than likes, and the arousal level was higher when dislikes predominated over likes, implying that more cerebral information processing activity was involved in answering dislikes than likes. In the case of cars, the difference between likes and dislikes was focused within a frequency band of 15-20 Hz in the right cerebral hemisphere. Our findings suggest that the activity in the right brain predominates with increases in negative emotion.

The characteristics of the rare earth phosphors intensifying screen (LM-6, Grenex-8) as compared with $CaWO_4$ intensifying screen had been studied utilizing several common x-ray films, and found the following results. 1. Compared with the conventional CaWO4 intensifying screen, the rare earth phosphors intensifying screen was found to be more sensitive over to 1.26-3.47 times. So the radiation exposure could be reduced to 1/1.26 -1/3.47. 2. Sharpness as well as the film speed were both increased. So the motion blurring and geometrical unsharpness could be decreased. 3. In spite of that the film speed was increased, photographic contrast was kept up. Therefore, the more ideal film of greater latitude could be obtained. 4. The effects of the rare earth phosphors intensifying screen would be much increased as using with orthochromatic x-ray films.

We have analyzed a set of high resolution photographic line profiles of a Zeeman sensitive Fe I $\lambda$ 6302.5 line taken with the Universal Birefringent Filter over a single round sunspot (SPO 5007) at the Sacramento Peak Solar Observatory. The observed spectra recorded on films are traced by PDS and the traced densities are converted to relative intensity by means of IRAF. The Stokes I and V profiles are then constructed by adding together and subtracting from each other the left and right handed circular polarizations, respectively. The reduced I and V profiles are analyzed by means of the coarse analysis(Auer et al.(1977), Skumanich and Lites(1987)) with the use of inversion technique. It is found that the umbral field strength is about 3000 gauss and the field distribution follows closely the emperical model proposed by Wittmann(1974).

Recently. a new technique called Electronic Speckle Pattern Interferometry(ESPI) has been developed to overcome the drawbacks of existing holography. This technique enable real-time interference fringes to be displayed directly on TV monitor without recourse to any form of photographic processing. This research was carried out for the purpose of applying the vibration analysis method employing Electronic Speckle Pattern Interference technique to the vibration analysis of uniform rectangular cantilever plate. The natural vibration frequencies found by ESPI were in fair agreement with theoretical eigen frequencies acquired using theoretical formula G. B. Warburton proposed.

The high-pressurized spray nozzle is used f3r special washing and cutting with strong impact force. The performance of this nozzle, which focused on spray penetration and radial dispersion, was mainly investigated to maximize the momentum and minimize the flow loss. Hence, our experimental research was conducted by changing the aspect ratio ranging from 0 to 3 with nozzle outlet of 1.1. The spray trajectory far high-pressurized water was experimentally investigated using PDPA diagnostics, which was available at spray downstream region. As the spray at upstream near the nozzle exit did not show the improved disintegration. The results showed empirical correlation with regard to non-dimensional axial velocity distribution, spray penetration, and radial spreading rate with photographic visualization.

In this study, the behavior of water or nanofluid droplets impacting upon a hot surface was investigated by visualization of impacting phenomena with time-delayed photographic technique. Changing the mass ratio of nanofluid and the temperature of the heated surface, the characteristics of the spreading behavior and the diameter of spreading liquid film was compared between water and nanofluid droplets. The impacting droplet spreaded as a liquid film after impact and nanofluid droplets spreaded more widely than water droplets. After reaching the maximum diameter, water droplets shrinked more than nanofluid droplets. Based on this, the heat transfer area from a hot surface to impacting nanofluid droplets would be wider than that of impacting water droplets. Considering individual impacting droplet only, spray cooling using nanofluid would be better than using water.
