The purpose of this study was to utilize of apparel CAD System by the classification of the basic pattern block in pattern making process. Gerber AM-300 CAD System was used for this study. The results form this study were as follows; 1. New shirts block were developed. 2. The sensory test was applied to evaluate the new shirts block for women by comparing it with Japanese Bunka shirts blouse pattern making method. According to a statistical analysis of the result of the 20 items on the questionnaire, the 19 items showed significant difference(${\alpha}{\leq}0.01$)between the two, with the new shirts block having higher scores. 3. A basic pattern block was selected by the design sketch. 4. P/D/S were enabled to be constructed directly from a block pattern. The drawing, deletion. duplication, and movement of all points and lines in the pattern might be made freely, and the split, pivot, and movement of the pattern, and the attachment of two patterns were possible. 5. Automatic grading of finished pattern have been developed by creation and modification of grading rules of block pattern.

The purpose of this study is to investigate the fitness according to drafting method of the block patterns for women in Korea. The major findings of this study are as follows: 1. According to comparative analysis of required measurements, two measurements of back length and bust girth are used in Proportional Drafting Method (Munhwa). In case of Compromise Drafting Methods are used across chest, across back, bust length, bust width, full length in front, across shoulder and shoulder length in addition to back length and bust girth. The type of Armstrong as a Short Measure Drafting Method uses 10 measurements for the drafting the bodice. 2. While Esmod block pattern arid Armstrong's block pattern are the lightest in full width and other widths. Rasara block pattern is the most ample. In Lee, Myung-hee's block pattern and Lee, Hyung-sook's block pattern, amounts of drooping are decided $3{\sim}4cm$, but drooping amounts of other block patterns are decided corresponding to real measurements. While cap height in Esmod and Armstrong's sleeve patterns are directly measured Armhole length of the block pattern, cap height of other sleeve patterns are used armhole depth and cap height length as well as armhole length. 3. When analyzing to indirect measurements, Esmod block pattern shows the least different between full length of block pattern and that of body form. Munhwa block pattern and Kim, Hyosook's block pattern are mostly same to body form back length. However all of the block patterns are sheller than body form length. In case of Suh, Wansuk's block pattern, across back and across chest are same size, but other block patterns show difference between across back and across chest. Most block patterns' neck width in front and bach bodice are almost same. Front neck width is generally bigger than back neck width in some cases.

The human body, which is composed of concave and convex curvatures, makes it difficult to transfer into 2D patterns directly from 3D data. In previous studies. Jeong, et al.(2004) suggested the block method was fester and easier when dealing with the triangular patches of male's upper dress form. Although the block method is useful to make a pattern, the information(area, length, etc.) from a 2D pattern would be different depending on the direction of the block method. As a result horizontal and diagonal block methods were suggested as optimal methods for 2D tight-fitting patterns. These block methods were closer to the original area of the 3D scan data than the vertical block method. The total area of the 2D pattern obtained by the horizontal and diagonal block methods showed little differences. In case of the horizontal and diagonal block methods, the total error of the 2D pattern area ranged from $0.01\%\~0.25\%$. In comparing the length of the 2D pattern with that of the 3D scan data, the obtained 2D pattern was $0.1\~0.2cm$ shorter than the 3D scan data, which was within the acceptable range of errors in making clothes. 3D space distribution images between the body surface and the experimental clothing were also measured and $3\%$ enlargement of the original pattern was verified as the adequate adjustment.

The purpose of this study is to investigate the fitness according to drafting method of the block patterns for women in Korea. The major findings of this study are as follows: 1. According to each sensory test of the frontal view, back view, side view and silhouette Block Pattern I is the best of them in summation of the sensory tests score. Block, Pattern D and I have good shape too. However the best block Pattern D shows good score in evaluation of overall fitness and silhouette. 2. Most of block patterns, which show high scores in sensory tests, are the Compromise Method taking merits of the Proportional Method and Short Measure Method among the Pattern Drafting Methods. Box-shape patterns show low score in the sensory tests. 3. Regarding to the number of measurement, the patterns of the Compromise Method using 6-8 measurements seem to be optimal. In degree of fitness, loose fit type basic patterns are better than other patterns from a viewpoint of the total satisfaction.

Recently, the quality and design of the children's wear is being improved remarkably. Following the trend, the need for the research on the pattern making of children's wear is growing. At first, we tried to find out how the industry is doing the pattern making job through interview. Results are as follows. The target age ranges from 5 to 11 years old. For the sample size of pattern making, 7 years of age is preferred. It is not usual to develop the design pattern from the bodice block pattern. Instead, they use middle block pattern for each item, such as blouse, shirt, pants, skirt or jacket. Starting from these middle block pattern, they prepare individual designs. With the results, the aim of the research became to develop one of most frequently used middle block pattern. The blouse block pattern was selected for that purpose. To look into the existing patterns, we selected 4 methods, i.e. NM-method, T-method, O-method, E-methods. Theses patterns were compared through wearing test for the evaluation of comfort and fit using trial garments. The results indicated the NM-method was best among them. Specially waist line position, shoulder shape and size allowance was adequate. Alteration and adjustment of pattern draft was made onto the NM-method. Allowances for the bust circumference, across chest, across back and depth of arm was adjusted for better comfort as well as fine fit. Sidelines of the bodice and the underarm seam of the sleeves were curved for styling. After another wearing test, the final pattern was suggested as a blouse block pattern for 7 years old girl.

It is remarkable that the children's wear market has been growing instead of declining birth rate. The parents are willing to pay more when they find children's wear of better design and improved quality. For better quality, it is necessary to research on the pattern making of children's wear. After the interview with the 10 leading children's brands, we found that they develop individual design pattern based on each items middle block pattern which characterize the brands design line. Most frequently used middle block is for casual pants. Through interview with pattern designers, comparative study of patterns drafting methods, wearing test of trial garments and altering and adjustment of patterns, we developed the casual pants block pattern for 7 years old boys.

The purpose of this study is to recognize the differences of visual evaluation by variations in pattern and silhouette of the block dresses. The stimuli are 9 samples: 3 variations of the silhouette and 3 variations of the size of pattern. The data has been obtained from 55 fashion students and has been analyzed by using Factor Analysis, Anova, Scheffe's Test and the MCA method. The results of this study are as follows; 1) The visual evaluation by pattern and silhouette of block dresses are composed of 4 factors: lovable personality, physical characteristics, boldness, and simplicity. 2) Block dresses were evaluated to display the figure more efficiently, such as looking slimmer or taller, in the order of 2nd stage, 1st stage, and 3rd stage in every silhouette. As the patterns became bigger, straight silhouette dresses were judged to have bolder, more dignified images. 3) Block dresses were evaluated to have cute and lively images in order of hourglass silhouette, straight silhouette, and fitted silhouette in every pattern. They were evaluated to appear slimmer and taller in order of hourglass silhouette, fitted silhouette, and straight silhouette in every pattern. 1st stage and 2nd stage dresses were evaluated to have a bolder, more dignified image in order of fitted silhouette, hourglass silhouette, and straight silhouette. 4) The pattern and the silhouette of the block dresses interacted with boldness. These were the boldest, most dignified image in the fitted silhouette and 1st stage, while they were not judged so in the case of the straight silhouette and 1st stage. 5) According to the MCA regarding lovable personality and physical characteristics, the silhouette affected the visual image of the block dresses more than the pattern did. According to the MCA on simplicity, the pattern affected the visual image of the block dresses more than the silhouette.

We propose a new content-based image retrieval using a block color co-occurrence matrix (BCCM) and pattern correlogram. In the proposed method, the color feature vectors are extracted by using BCCM that represents the probability of the co-occurrence of two mean colors within blocks. Also the pattern feature vectors are extracted by using pattern correlogram which is combined with spatial correlation of pattern. In the proposed pattern correlogram method. after block-divided image is classified into 48 patterns with respect to the change of the RGB color of the image, joint probability between the same pattern from the surrounding blocks existing at the fixed distance and the center pattern is calculated. Experimental results show that the proposed method can outperform the conventional methods as regards the precision and the size of the feature vector dimension.

Color image processing based on smoke detection is suitable detecting target to early detection of fire smoke. A method for detecting the smoke is processed in the pre-processing movement and color. And Next, characteristics of smoke such as diffusion, texture, shape, and directionality are used to post-processing. In this paper, propose the detection method of density distribution characteristic in characteristics of smoke. the generate a candidate regions by color thresholding image in Detecting the movement of smoke to the 10Frame interval and accumulated while 1second image. then check whether the pattern of the smoke by candidate regions to applying OBTP(Object Block Ternary Pattern). every processing is Block-based processing, moving detection is decided the candidate regions of the moving object by applying an adaptive threshold to frame difference image. The decided candidate region accumulates one second and apply the threshold condition of the smoke color. make the ternary pattern compare the center block value with block value of 16 position in each candidate region of the smoke, and determine the smoke by compare the candidate ternary pattern and smoke ternary pattern.
