In this paper, actual didactical transposition and dramatization of designing patterns presented in 4th grade mathematics curriculum is critically reviewed. Patterns in designing patterns are not wallpaper patterns generally. The method of designing new patterns using unit given pattern are not the same as the method of designing wallpaper patterns. In the viewpoint of not designing wallpaper patterns, the context of designing new patterns using unit given pattern is said to be putting transparent stickers. In this paper, on the premise of this characteristics, the shape of unit given pattern, the method of designing new patterns using unit given pattern, and the rule of putting unit given patterns continually are critically discussed. The shape of unit given pattern have to be square actually. In designing new patterns using unit given pattern, if the regularities of designing new patterns can be presented, any regularity is fine. Even though the relationship between new patterns and wallpapers designed by using unit given pattern is not clear, in that these two patterns can not be unrelated, designing new patterns using unit given pattern could be an example of wrong elementarization(Freudenthal, 1973).

The purpose of this study is to suggest a designing method with excellent body suitability by analyzing clothingwearing porosity, comparing and analyzing patterns, and evaluating outer appearances by designing a prototype of study applied with design measurements for categories that have influence on the outer appearance of clothing through diverse research methods, by comparing and analyzing bunka and new bunka style basic pattern, which are proportional basic patterns most frequently used in schools for educational use to design bodice pattern for elderly women in their late 60s. As for the process of this study, the first stage selected study subjects, measured bodies. The second stage compared patterns of bunka and new bunka style basic pattern and evaluated outer appearances that deduced important pattern designing categories to design upper-torso bodice pattern of elderly women. The results of this study are as following ; As a result of comparing and analyzing bunka and new bunka style basic pattern, overall evaluation of outer appearance was excellent for new bunka style basic pattern, and bunka basic pattern received better reviews for the width and depth of front neck. In terms of waist circumference, waist front length, bust point location and bust point-bust point, bunka and new bunka style basic patterns showed a significant difference. new bunka style basic pattern had 4.5cm larger front armhole depth than bunka basic pattern, so it was evaluated to have more appropriate front armhole length, bust point location, and bust point-bust point. Through observation for primary excellent categories and precedent studies, 7 categories of front neck width, front neck depth, front interscye, back neck width, back neck depth, back interscye, and back armhole depth were deduced to have relations to the extra room around arm holes and waist that affect pattern designing method and porosity and evaluations of outer appearance.

In order to understand the current state of production and pattern design of circular knitted jackets, this study selected 11 female clothing brands based from the "2012/2013 Korea Fashion Brand Yearbook" and interviewed the staff in charge of patterns at the companies. Polyester and polyurethane were found to be synthesized and used for the outshell of circular knitted jackets, alternatively natural fabric cotton or wool were synthesized with rayon. As for the structure of circular knitted materials, Ponte Di Roma knitting structure (a modified form of a double knit) was most often used. Surveying the use pattern and the parts for padding cloth, six responded that they used elastic padding cloth. As for circular knitted jackets with inner lining, elastic padding cloth was attached to all parts (front, back, side panel, and collar - except for sleeves) of the basic bodice pattern. Eight responded that they did not use a basic pattern when designing a pattern, which exceeds the majority. All respondents answered yes to the question on if there is any difference in designing a pattern for a woven jacket and a circular knitted jacket. It was found that they designed a pattern that considered shrinkage and elongation, which are the features of circular knitted fabric. Shrinkage and elongation were the features of a fabric material most considered when designing patterns for a circular knitted jacket.

This research aimed to study the making of western men's coats in the early 19th century. First of all, the study figured out the concepts and forms of western men's tops in the early 19th century by collecting and categorizing pictures including engravings, paintings and pattern books, and literature data. Second, this research identified the patterns, sewing, and design techniques by examining the pattern books on men's clothing in the early 19th century, and analyzed the preserved costumes to restore the selected models. Third, this research presented historical evidences and patterns after designing a men's tailcoat of the early $19^{th}$ century and checking the fit based on the analyzed forms and design techniques. The research discovered that the analyzed results between the tailcoat forms depicted in literature, pictures and pattern books and preserved costumes were almost identical. From this, it can be assumed that the tailors followed a manual when designing garments during that time given the similarity between historical records and remaining items. In addition, it can be seen that the forms and designing methods of men's clothing in the 19th century were almost similar to that of the modern menswear, despite the differences in producing process.

Microstructure pattern generation on light guides in backlight unit (BLU) is an essential process for designing flat panel display, but efficient designing algorithm is still limited to achieve uniform luminescence while maintaining fully random distribution to avoid interference effects. In this study, a molecular dynamics model based pattern generation algorithm has been developed. The proposed algorithm allows a fast and efficient distribution of patterns at specified density within the user-defined computational cells, and its efficiency and performance has been demonstrated with sample cases.

With suffering financial crisis in 1997, Korea's fashion market has grown in the direction that satisfies the reasonable price and diverse consumer's sensitivity and needs. The aim of this study is to examine whether the cutting portion in the waist line is surely necessary for designing the jacket pattern in men's wear, by closely examining the effects of the cutting portion in the waist line on the external appearance and functionality given designing the jacket pattern in men's wear for the standard body type in 20s. The results of the study are as follows. As a result of evaluating the external appearance, when having evaluated by dividing into 14 items such as the whole surface, the side, and the back side, the experimental clothing, which wasn't cut the waist line, obtained the highest mark in 13 items and, the significant difference was indicated in 10 items except 4 items. As a result of evaluating performance, the experimental clothing, which wasn't cut the waist line, obtained the highest mark in 13 items among 25 items in the total. Next, the cutting portion in the waist line obtained the highest mark in 10 items for the experimental clothing with opening in 1.0cm. The next was indicated to be in order of the experimental clothing with 1.5cm and the experimental clothing with 0.5cm. Given seeing the above result, the cutting portion in the waist line given designing the jacket pattern for the standard body type in 20s could be known that the experimental clothing with the most excellent mark in the evaluation of performance was all the experimental clothing with 0.0cm whose waist line wasn't cut.

The pattern query in graph database has advantages of easy query expression and high query processing performance compared to relational database SQL. However, unlike the relational database, the graph database may not utilize the advantages of pattern query depending on modeling because the methodology for building the logical data model is not defined. In this study, in the is-a node modeling method that appears during the graph modeling process, we experiment that there is a difference in performance between graph pattern query when designing with a generalization model and designing with a specialization model. As a result of the experiment, it was shown that better performance can be obtained when the is-a node is designed as a specialization model. In addition, when writing a pattern query, we show that if a variable is bound to a node or edge, performance may be better than that of the variable of not bounded. The experimental results can be presented as an is-a node modeling method for pattern query and a graph query writing method in the graph database.

The purpose of this study is to analyze the ease of stretchable jackets which has been common since the mid-1990s and the whole actual conditions in making the lining fabrics. This can be done by investigating the actual conditions of domestic clothes businesses about the consumers. The outcomes of this study are as follows; The result of the survey in the differences of the ease between regular and stretchable fabrics shows that the pattern of designing stretchable fabrics needs diminishing the width of shoulder is 0.42cm, the whole girth chest is 1.83cm, the whole girth of waist is 0.88cm. It also shows that designing the ease of the whole girth of chest is 1.91cm to 2.54cm in the regular lining fabrics and is from 0 to 1.27cm in the stretchable fabrics more than the right side of fabrics. The ease of the whole girth of waist is similar to the round chest, in which the bottom sweep for garment is almost equal to the right side of fabrics in both regular lining fabrics and stretchable fabrics. The result of investigating the actual conditions of making the lining fabrics of stretchable jacket fabrics shows that 80% of a woman's wear brand produces and gives the pattern of the lining fabrics only for the special designing to the cooperative clothes manufactures. The business which always provides the patterns for the lining fabrics in the main office is only limited to 20%. Also, it shows that using the lining fabrics of stretchable jacket fabrics and regular lining fabrics together is 46.7%, the stretchable lining fabrics is 40% and the regular lining fabrics is 13.3% only.
