This study investigated the annual frequency and clothing type by extracting puff sleeves designs from overseas fashion collections from S/S and F/W 2017 to S/S and F/W 2019. Specifically, it analyzed production characteristics and pattern methods by the type of puff sleeve design, and found the following: In terms of the percentage of puff sleeves by season, S/S 2019 was the highest. Since Newtro, with a 1990s sensitivity, was the mainstream trend during the S/S 2019, power puff sleeves, a signature of the Newtro style, accounted for the greatest portion of this design feature. In terms of the type of clothes with puff sleeves, 'dress' (54.3%) was the highest, followed by 'shirts/blouse' (27.5%), 'jacket/coat' (12.5%), and 'padded coat/jacket' (5.7%). Specifically, puff sleeve patterns were found mostly in the 'dress' category, more than 47% every season, while the figures were more than 23%, 9.3%, and 2.6% in 'shirts/blouse', 'jacket/coat' and 'padded coat/jacket', respectively. In other words, puff sleeve designs were more common in 'dress' or 'shirts/blouse' than in a 'padded coat/jacket'. In general, the shoulder length is reduced to prevent the shoulders from looking broader because of puffs. In contrast, recent puff-sleeve styles differ from those introduced by modern fashion designers in that they have drop shoulders with puffs attached. Furthermore, as constructive and over-exaggerated sleeve patterns appeared, puffs were applied to diverse sleeve styles including mutton leg and Mameluke styles. The analysis results of this study will contribute to the development of the fashion industry through small quantity batch production pursuing unique styles and serve as the basis for further studies on the configuration methods of puff sleeves. This study will be used in various ways, including as educational material on sleeve patterns. Through the analysis of sleeve patterns, this study tries to provide basic data for planning the design of puff sleeves and helping to diversify the ladies' apparel market in the future.

A comparative study of major brands of domestic and imported cigarettes saled in market has been conducted. The total amounts of total particulate matter(TPM), tar and nicotine delivered from cigarettes, as well as the amounts of tar, nicotine in puff by puff were determined in the mainstream smoke of 6 brands. In addition, the relative amounts of vapour phase in 3rd puff smoke were determined. Results showed that the amounts of TPM and tar delivered from domestic brands were similar to the imported brands and the amounts of total nicotine delivered from domestic brands were higher than those of imported brands. As the domestic cigarettes nicotine/tar(N/T X 100) ratio was 9.5-10.3, the imported one's was 5.6-8.1. However, the amounts of tar and nicotine in puff by puff for the domestic brands were lower than those of the imported cigarettes and the relative amounts of vapour phase in 3rd puff smoke for the domestic cigarettes were lower than those of the imported cigarettes.

The purpose of this study is to evaluate the differences of visual effects by variations in the shoulder length and puff volume of the puff sleeve blouse. The stimuli are 21 samples: 3 variations of the shoulder length and 7 variations of the puff volume. The data has been obtained from 40 fashion design majors. The data has analyzed by Frequency, Factor Analysis, ANOVA, Scheffe's test and MCA method. The result of the study are as follows. The visual effects by the shoulder length and puff volume are composed of 4 factors : the width of the upper body, the shape of the breast part, the shape of the neck part and the shape of the upper arm. In these factors, the width of the upper body is estimated by most important factor. In view of the visual effects by variation of the shoulder length, the shorter shoulder length goes, the more positive visual image comes in the shape of the breast part. In comparison of the differences of visual effects by the 7 variations of puff volume, the arm looks thin and long when the puff volume goes enough and the breast part has a better visual assesment in case the puff volume goes poor. In the interaction effects between the shoulder length and puff volume, the shoulder length have significant differences in the shape of the breast part, the shape of the neck part and the shape of the upper arm and puff volume has significant difference in the width of the upper body.

The purpose of this study is to evaluate the differences among visual images under variations in shoulder length and puff volume of the puff sleeve blouse. The stimuli are 21 samples: three variations of shoulder length and seven variations of puff volume. The data has been obtained from 40 fashion design majors, where they had been analyzed through frequency, factor analysis, ANOVA, Scheffe's test and MCA method. The results of the study are as the following: As a result, through factor analysis of the visual images according to the variation of shoulder point and puff volume, the following four factors had been identified. Factor 1 is the brightness from evaluation terms such as childish-precocious, cute-mature, bright-genteel, soft-hard, enlarged-reduced, particular-ordinary, interesting- uninteresting, etc. Factor 2 is the attractiveness from evaluation terms such as refine-rustic, stylish-dull, attractive-unattractive, modern-classic, urban-rural, cool-gloomy, spacious-tight. etc. Factor 3 is the comfortness from evaluation terms such as comfort-discomfort, intense-indistinct, etc. Factor 4 is the elegance from evaluation terms such as elegance-shallowness, womanish-manly, etc. These four factors were 66.7% of the total variables. Of the total variables, the first factor had been evaluated as brightness in 26.2%, attractive in 21.0%, comfortness in 11.1%, and elegance in 8.4%. From this study, the more puff volume and shorter shoulder length, the puff volume wrapped the shoulder naturally, thus making the shoulder look narrow, and giving a cute and bright image. However, by having less puff volume and excessively short shoulder length, the puff volume did not naturally wrap the shoulder, which gave an unnatural and unattractive feel.

This study was carried out to investigate the effect of pastry margarine content and number of layers on moisture content, baking loss, specific loaf volume and the vapor action in the manufacturing process of puff pastry. As the number of layers of the puff pastry increased the moisture content of the products slightly increased. And the moisture contents of the products decreased, as the pastry margarine contents of the puff pastry increased in the same number of layers. The baking loss of the products tended to decrease as the number of layers increased. On the other hand, as the pastry margarine contents of the puff pastry increased, the baking loss of the product increased. When the pastry margarine content in puff pastries became 130%, 81 layers provided the maximum specific loaf volumes $21.62{\pm}0.79\;ml/g$ of puff pastries. When 110% of margarine and 256 layers were applied for preparation of puff pastry, the number of vapor action was $8.25{\pm}0.50$ with the vapor action size of 9-15 mm.

Intraocular pressure is measured after a cornea air puff by observing biomechanical properties such as thickness or displacement of the cornea. In this paper, we deal with a frequency domain analysis of corneal deformation in the air puff tonometry that is used to diagnose glaucoma or lasik. We distinguish the patient from the normal by measuring the oscillation frequency in the neighborhood of the central cornea section. A binary image was obtained from the video images, and cornea vertical oscillation profile was extracted from the difference between the vertical displacement data and the curve fitting. In terms of Fourier transform, a vibration frequency of 479.2Hz for the patient was obtained as well as more higher 702.8Hz for the normal due to stiffness. Hilbert-Huang transform's empirical mode decomposition generally describes local, nonlinear, and nonstationary data. After the data were decomposed into intrinsic mode functions, a spectrum and power were analysed. Finally, we confirm that the patient has 6 times more higher power ratio for the specific intrinsic mode function between the patient and the normal.

The computations of the flowfield and pollutant dispersion over a flat plate and the Russian hills of various slopes are described. The Gaussian plume and the puff model have been used to calculate concentration of pollutant. The Reynolds-averaged unsteady incompressible Navier-Stokes equation with low Reynolds κ-ε model has been used to calculate the flowfield. The flow data of a flat plate and the Russian hills from Navier-Stokes equation solutions has been used as the input data for the puff model. The computational results of flowfield agree well with experimental results of both a flat plate and Russian hills. The concentration prediction by the Gaussian plume model and the Gaussian puff model also agrees flirty well with experiments.

This study examined the correlation between a handle evaluation of cosmetic puff textile and a sensory evaluation. The KES-F system was used to analyze the main mechanical factors for the handle evaluation and a statistical method was used for the sensory evaluation. The results revealed different mechanical properties and handle values of the tested cosmetic puff textiles. A material type and structure of the cosmetic textile affected the handle property of the material which is the most important factor for a cosmetic purpose. Particularly, the physical properties of textile material are likely to be important factors for the sensory property of cosmetic material. In addition, the sensory evaluation also revealed different sensory characteristics of the cosmetic efficiency according to the cosmetic puff textile. No close relationship was observed between the mechanical properties and sensory evaluation on the cosmetic puff textiles. The sensory evaluation of a cosmetic efficiency is not only decided by the physical and mechanical characteristics of the cosmetic textile material. Overall, when using textiles used for the cosmetic purposes, it is important to consider not only the proper mechanical properties of the textiles but also the use and sensory satisfaction. Development and selection of the cosmetic textiles should be focused on both the material function and consumer satisfaction.

Effects of changes in the margarine content and the number of layers of the puff pastry on the color, hardness, and hardness change during storage of the final products were investigated. At equal content of pastry margarine, the lightness of the crust decreased slightly as the number of layers increased. Redness of the puff pastry with 70% margarine content and 81 layers was $16.8{\pm}2.3$ and yellowness of puff pastry with 70% margarine content and 256 layers was 26. No significant differences were observed in the crumb change of the samples. The puff pastry with 90% margarine content and 144 layers showed the lowest hardness of $839.6{\pm}75.6g$. Hardness of the products storage period increased significantly as the number of layers increased at equal pastry margarine content, whereas with same number of layers, decreased gradually as pastry margarine content increased. Results of the sensory evaluation reveal that the puff pastry with 90% margarine content and 144 layers was better than other samples. These results show the important of selecting the optimum number of layers during the manufacturing process to obtain the optimum condition for the mouthfeeling, flavor and overall acceptability of final products.

The puff models have been developed to simulate the advection-diffusion processes of dredging suspended solids, either alone or in combination with Eulerian models. Computational efficiency and accuracy are of prime importance in designing these hybrid approaches to simulate a pollutant discharge, and we characterize two relatively simple Lagrangian techniques in this regard: forward Gaussian puff tracking (FGPT), and backward Gaussian puff tracking (BGPT). FGPT and BGPT offer dramatic savings in computational expense, but their applicability is limited by accuracy concerns in the presence of spatially variable flow or diffusivity fields or complex no-flux or open boundary conditions. For long simulations, particle and/or puff methods can transition to an Eulerian model if appropriate, since the relative computational expense of Lagrangian methods increases with time for continuous sources. Although we focus on simple Lagrangian models that are not suitable to all environmental applications, many of the implementation and computational efficiency concerns outlined herein would also be relevant to using higher order particle and puff methods to extend the near field.
