The aim of this study was to analyze the features of bodice patterns modeled using a dress form that represents Korean female fashion models' body features. A controlled experiment was carried out using an existing dress form that has been frequently used in South Korea. The purpose of the study was to suggest notable findings derived from understanding the development of bodice patterns for Korean female fashion models. The comparison of features of bodice patterns from the developed and existing dress forms was carried out with consideration of the upper body features of the developed dress form, such as body angles and body cross-sectional shapes. The following results were derived from the investigations. (1) The angles of the upper and lower breast cups of the developed dress form differed to those of the existing dress form, showing a 5.0cm smaller front shoulder dart and a 3.5 larger ㎝ ㎝ front waist dart within the bodice patterns. (2) The body angle features of the developed dress form included a straighter neck and shoulder blade and more concave center back than the existing dress form, with a 2.0 reduced back neck height and a 4.8 larger back waist dart for ㎝ ㎝ the bodice back panel. The more realistic body angles of the developed dress form anticipate the improvement of garment pattern-making. (3) The altered shoulder angles resulted in an increased size of the back shoulder dart and a decreased size of the front shoulder height within the bodice patterns. (4) The increased rate of curvature of cross-sectional shapes on the bust and waist circumferences of the developed dress form resulted in an increase in the sizes of the front and back waist darts.

Quantizing and extracting visual features of mushroom(Lentinus edodes L.) are crucial to the sorting and grading automation, the growth state measurement, and the dried performance indexing. A computer image processing system was utilized for the extraction and measurement of visual features of front and back sides of the mushroom. The image processing system is composed of the IBM PC compatible 386DK, ITEX PCVISION Plus frame grabber, B/W CCD camera, VGA color graphic monitor, and image output RGB monitor. In this paper, an automatic thresholding algorithm was developed to yield the segmented binary image representing skin states of the front and back sides. An eight directional Freeman's chain coding was modified to solve the edge disconnectivity by gradually expanding the mask size of 3$\times$3 to 9$\times$9. A real scaled geometric quantity of the object was directly extracted from the 8-directional chain element. The external shape of the mushroom was analyzed and converted to the quantitative feature patterns. Efficient algorithms for the extraction of the selected feature patterns and the recognition of the front and back side were developed. The developed algorithms were coded in a menu driven way using MS_C language Ver.6.0, PC VISION PLUS library fuctions, and VGA graphic functions.

Visual features of a mushroom(Lentinus Edodes, L.) are critical in grading and sorting as most agricultural products are. Because of its complex and various visual features, grading and sorting of mushrooms have been done manually by the human expert. To realize the automatic handling and grading of mushrooms in real time, the computer vision system should be utilized and the efficient and robust processing of the camera captured visual information be provided. Since visual features of a mushroom are distributed over the front and back sides, recognizing sides and states of the stalk including the stalk orientation from the captured image is a prime process in the automatic task processing. In this paper, the efficient and robust recognition process identifying the front and back side and the state of the stalk was developed and its performance was compared with other recognition trials. First, recognition was tried based on the rule set up with some experimental heuristics using the quantitative features such as geometry and texture extracted from the segmented mushroom image. And the neural net based learning recognition was done without extracting quantitative features. For network inputs the segmented binary image obtained from the combined type automatic thresholding was tested first. And then the gray valued raw camera image was directly utilized. The state of the stalk seriously affects the measured size of the mushroom cap. When its effect is serious, the stalk should be excluded in mushroom cap sizing. In this paper, the stalk removal process followed by the boundary regeneration of the cap image was also presented. The neural net based gray valued raw image processing showed the successful results for our recognition task. The developed technology through this research may open the new way of the quality inspection and sorting especially for the agricultural products whose visual features are fuzzy and not uniquely defined.

In this study, the photographic and anthropometric measurements of men in the 20's were made. and pattern making professionals visually evaluated their side photos to classify lateral views. These data were analyzed by being compared with existing research results to select objective standards, and body types were classified according to the selected standard. In addition, body features were defined according to lateral views based on measurement items and indices, and standard lines and determining factors for visual evaluation which determines lateral views were revealed. Back length - front length size smaller than 1.5cm was named as the lean-back type, 1.5∼3.9cm was named as the straight type. and that larger than 3.9cm was named as the bend-forward type. In the straight type, the bisection point of waist depth was located at a similar place to tragion level vertical line. In the lean-back type, the point was at the front of tragion level vertical line. In the bend-forward type, the point was at the back of tragion level vertical line.

Recently, with increasing efficiency of DSC (photo-electrochemical using a nano-particle), The Performance of DSC solar generation system also needs improvement. The approach consists of a Fly-back DC-DC (transfer ratio 1:10) converter to boost the DSC cell voltage to 300VDC. The four switch (MOSFET) inverter is employed to produce 220V, 60Hz AC outputs. High performance, easy manufacturability, lower component count., safety and cost are addressed. Protection and diagnostic features form an important part of the design. Another highlight of the proposed design is the control strategy, which allows the inverter to adapt to the: requirements of the load as well as the power source. A unique aspect of the design is the use of the DSP TMS320LF2406 to control the inverter by current and voltage feed-back. Efficient and smooth control of the: power drawn from the DSC Cell is achieved by controlling the front end DC-DC converter in current mode.

We investigated the perceptual structure of Korean consonants by analyzing the confusion among consonants in various vowel contexts. The 36 CV syllable types combined by 18 consonants and 2 vowels (/i/ and /u/) were presented with masking noises or in degraded intensity. The confusion data were analyzed by the INDSCAL (Individual Difference Scaling), ADCLUS (Additive Clustering) and the probability of the transmitted information. The results were compared with those of a previous study with /a/ vowel context (Bae and Kim, 2002). The overall results showed that the laryngeal features-aspiration, lax and tense-are the most salient features in the perception of Korean consonant regardless of vowel contexts, but the perceptual saliency of place features varies across vowel conditions. In high vowel (front and back vowel) contexts, sibilant consonants were perceptually salient compared to in low vowel contexts. In back vowel contexts, grave (labial and velar) consonants were perceptually salient. These findings imply that place features and vowel features strongly interact in speech perception as well as in speech production. All statistical measures from our confusion data ensured that the perceptual structure of Korean consonants correspond to the hierarchical structure suggested in the feature geometry (Clements, 1991). We discuss the link between speech perception and production as the basis of phonology.

The study was aimed to develop a torso-type dress form representing body features of the female fashion models in Korea. To fulfill this purpose, 5 female fashion models aged between 20 and 26 having the average body measurements of professional fashion models in Korea were selected and their 3-D whole body scanned data were analysed. The 3-D whole body scanning method enabled to generate a virtual female fashion model within the CAD system by measuring the subjects' body shapes and sizes. In addition, the virtual model's body data led the development of a standard female fashion model dress form for the efficient fashion show preparation. In order to manufacture the real dress form for female fashion models, 3-D printing technology was adopted. The consequent results are as follows: (1) the body measurements (unit: cm) of the developed dress form were: biacromion length, 36.0, bust point to bust point, 16.6, front/back interscye lengths, 32.0/33.0, neck point to breast point, 26.0, neck point to breast point to waist line, 41.5, waist front/back lengths, 34.5/38.5, waist to hip length, 24.0, bust circumference, 85.0, underbust circumference, 75.0, waist circumference, 65.0, hip circumference, 92.0. (2) the body measurements differences between the developed and existing dress forms were highlighted with the body measurements of neck point to breast point and waist to hip length. (3) the body shape features of the developed dress form showed that bust, shoulder blade, shoulder slope, abdomen and back waist line to hip line parts were more realistically manufactured.

This study developed an ideal jeggings pattern with an improved body fit for 20-24 year old females. The results of the study are as follows. First, samples for wearing test were made using jegging patterns from three manufacturers; subsequently, one pattern with a relatively outstanding body fit was selected from the first test. The selected pattern suggested a tight knee, belly, and crotch, high front waist line, and low back waist line. The side lines were also lean to the front; consequently, the front hip width was extended for 0.5cm for more space around the belly and the extended front knee part for 0.2cm to increase moving suitability to fix the leaning side lines. A 1cm front waist line was extended for 0.5cm to fix it lower; in addition, the back waist line 3.0cm was extended for 0.5cm to heighten it. The crotch width was also extended for 0.5cm to add more space. The second wearing test for the fixed forms were evaluated for their outstanding features in appearance as well as moving functions that were proposed as final jeggings forms. The results of the study suggested a jeggings pattern with a better body fit using manufacturer patterns that can be used as basic data for pant patterns with better fitting using various stretch fabrics.
