The present study deals with developing a new modem design of quilt which is characteristic of Korean traditional patterns. The goal of this study is to make some samples of the pattern as a basic motive of quilt work by using some Korean traditional patterns that could be found in roof tiles, windows, Neung-Hwa (a kind of wood cut for printing book covers), and others. This study examines the concept of quilts, their historical background, and their characteristics. This study also examines traditional patterns that are applicable to the patchy work of quilt, discussing the characteristic of both the Korean patterns and Nubi (Korean traditional quilt). In the process of pattern development, the original patterns were simplified and transformed to apply them to the modem quilt pattern. Fabrics (100% cotton) of similar colors were used to emphasize quilting lines. This study has found followings; 1) The geometric pattern usually consists of dots, lines, and faces. These patterns are suitable for pieced quilts. 2) The curvilinear pattern found in roof tiles or Yi-Dynasty coins, can be easily re-expressed by the applique technique. Combinations of fabrics and motive compositions can express quilts in realistic and creative ways. 3) Addition of Korean traditional quilt techniques, such as parallel lines or swastika stitches, to the traditional object-derived quilt patterns led to the creation of images close to the already existing Korean quilt, Nubi.

This study investigated underwear consumption behavior of women, who were 20∼59 years old and resided in Incheon during 2002 summer. 372 women completed questionnaires, and data were analyzed using factor analyses, t-test, ANOVA, $\chi$$^2$-analyses. They usually purchased underwear considering comfort and economic factor at a discount store. They wore sleeveless T-shirts, but they didn't wear underpants except panties highly all the year round. Higher rate of them wore pantyhose instead of underpants during autumn, winter and spring. They demanded unstitching of stitches and lengthened sleeves in most of the groups. And older and lowly educated women group wanted widen armhole of upper underwear, and tighten waistband of panties. They generally washed in washing machine using cold water. Besides they added oxygen bleach and softner during wash and final rinse. Older than 20's boil their underwear frequently. The women in a group of boiling commonly answered the looseness of waistband. It is recommended not to boil but to soak with bleach added warm water for improving the whiteness and durability of underwear. For a treatment with higher temperature deprives the elasticity of spandex.

The National Computerization Agency has been leading the Information Systems(IS) audit since 1987, as development of IS projects in governmental and public sectors have become daily issues. While many considerations on audit guidelines and techniques for quality management in IS have been given to respond to the fast increasing demand of audit process since mid 1990's, the study on the fact that how audit activities directly affect the quality of software process has been put aside. In this paper, we went through 74 audit results, which were reported by H auditing organization, and performed on 59 IS projects carried on 1999 through 2001. As a result of study, we found that more than one fourth of errors of Coding and Test phases are caused in the earlier phases, which naturally leads to the conclusions that auditing on earlier phases can save a lot of stitches in the later phases. Comparing two types of IS projects-the one that went through only one audit process, and the other that went through two audit processes-, we found that projects with two audits carry less errors on Planning, Analysis, Design phases as a whole, which revealed the facts that IS audit actually gives positive effects on the quality of software.

The purpose of this study is to develop the appropriate brassiere pattern for women. Total of 6 brands with same design and 75A, 80A size brassieres(total 12 brassieres) were compared and analyzed for pattern, cup size and patterns. SPSS 10.1 statistic process was used for data analysis. The outcom of this study is summarized as follows. Total length of brassiere by grade were performed smaller than the standard difference 5cm. For 1/2 front cover length, There were no significant differences between 75 and 80. The reason for lower line of wing is shorter than upper line of wing is because side support is cut side ways considering lower line of wing is sewn more toward front than upper line of wing. Even it is same A cup size most cup related sizes become larger according to underbust comparing with cup capacity, they range from 146.67cc to 172.83cc for same A cups. Among same A cups with difference underbust there was average of 26.16cc differences. For relations of material, sewing technology and expansion rate, all 6 brands had zigzag type sewing for upper line tape. For every 0.3cm height, there were $17{\sim}21$ stitches. When urethane mixture is similar expansion rate is higher while number of 1 inch zigzag are high. For elasticity, zigzag stitch expand side ways for more expansion.

Cable knitting, one of the most representative structures of knitwear has been applied to a number of knit items in a variety of expressions every season. The purpose of this study is to analyze the various types of expressions applied with cable knitting techniques to make the necessary data for planning cable knit designs. The types of cable knitting were devide into two categories which are based on the cable knitting pattern and structure. Based on the pattern, firstly, formal type is a reproduction of traditional Aran knit style and is usually applied to a practical and comfortable timeless knit product. Secondly, informal type is irregular applied to patterns and directions to highlight the dynamics of cable patterns. Thirdly, contrasting type emphasizes the cable pattern by contrasting the color of the part of the cable pattern. Fourthly, figurative type is the expression of the conceptual motifs and using the cable knit pattern itself as motif. Based on the structure, firstly, open type is to emphasize patterns and spaces by utilizing open spaces created by the intersection of cabling stitches. Secondly, decorative type is to enhance the ornamental effect of cable knitting by various methods and other subsidiary materials. Thirdly, avant-garde type is applied in various ways with exaggerated volumes or textures using the three-dimensional effects of cable knitting. Through this study, we look forward to the possibility of expressing the unique aesthetic characteristics of each of the various knitting techniques.

Seam puckering and the seam strength of conductive threads used to produce smart clothing were analyzed according to stitching methods and fabrics. Samples were prepared in a lock stitch and zigzag stitch on plain woven and jersey knit fabric, using one type of polyester sewing thread and three types of commercial conductive threads that consisted of two types of stainless-steel conductive threads (TST and MST) and one type of silver conductive thread (SSV). Seam pucker percentages, shapes, and seam strength were measured. On plain woven fabric as well as jersey knit fabric, three-ply TST and MST showed a higher SP percentage compared to a polyester sewing thread. Meanwhile, single-ply SSV showed the lowest SP percentage. In addition, the SP percentage of the zigzag stitch decreased along the weft and course directions of the fabric, and decreased significantly as the number of fabric layers increased. Moreover, there was a marked tendency for a higher SP percentage in jersey knit fabric compared to plain woven fabric, and the two-dimensional cross-section waveforms of stitches obtained using three-dimensional data that showed increased irregular waveforms and peaks in the zigzag stitch. There were no correlations between seam strength and tensile strength.

The objective of this study is to examine the current status of manufacturing formal knit jackets for middle-aged women. Fifteen manufacturers specializing in formal knitwear brands were chosen as the study subjects, and interviews and questionnaires were used with patterners and designers. The questionnaire was composed of 27 items and began with general questions, such as how the jackets were manufactured. Specific questions, such as materials and sewing method, were also considered further on. The results are as follows: First, as for the structure of the knit jacket manufacturer, seven out of fifteen manufacturers directly manufactured knit jackets in their own factory, while the manufacturing was comprised of 20% woven jackets and 80% knit jackets for all manufactures. Second, as for the type of yarn mostly used in knitting the fabric for the jackets, satin yarn and wool were used mostly for F/W with Plain and Half Milano rib stitches as the type of knit with a gauge of 12G and 7G. Third, as for the margin between the product size of the target brand and the size of the body at the time of designing a knit jacket pattern, the investigation of the actual state of manufacturing showed that the margin at the bust was B+4.8cm, the waist was W+6.9cm, and the hip girth was H+5cm. Therefore, the bust and hip girth of the knit jackets were designed to be smaller than those of the bust and hip girth lines of non-flexible woven jackets. On the contrary, the waist measurement of non-flexible woven jacket was designed to be smaller than the knit jacket. It was found that the side line of the knit jacket was expressed with greater give as compared to that of the non-flexible woven jacket.

Knitted fabric using acrylic/wool blended yarn (A/W) is increasingly used in the knit industry; subsequently, research on knitted fabric using A/W has increased. This study presents an scientific database from evaluating physical properties of $1{\times}1$ rib stitch using A/W. In this study,$1{\times}1$ rib stitch using A/W were made at various knitting tensions (dial no. 2-6) and the number (4-6) of ply yarn. The physical properties of $1{\times}1$ rib stitch using A/W were measured and analyzed. The density was in the range 5.5-6.4 wales/cm and 4.0-5.6 courses/cm, respectively. The density increased when less plying yarns and more knitting tension were added during knitting. The thickness was in the range of 1.592-2.362 mm and the tensile strength was in the range 32.75-53.63 Kgf/mm. The burst strength was in the range 107.8-139.2 $N/cm^2$. Thickness, tensile strength, and burst strength increased as the number of ply yarn and the knitting tension increased. The elongation and the recovery extension rate were in the range 102.29-112.13% and 96.4-97.7%, respectively. The heat retention rate was in the range 59.3-65.1%. There was no difference of the elongation and the recovery extension rate and the heat retention rate by the knitting tension and the number of the ply yarn. The permeability was in the range 170.5-396.3 $cm^3/cm^2/sec$. Air permeability decreased as the number of ply yarn and the knitting tension increased. The pilling properties were excellent for all $1{\times}1$ rib stitches.

Purpose: The purpose of this study was to examine the level of knowledge and learning needs of patients with a permanent pacemaker implantation. Methods: The participants were 86 patients with a permanent pacemaker implantation. Data were collected during April and May 2002 using a questionnaire survey on knowledge and level of learning need. The collected data were analyzed using the SAS program. Results: 1. The average knowledge score was 13.21. The knowledge level was significantly higher in participants under 50 years of age and for those with higher levels of education. The items with the highest knowledge score was 'permanent pacemaker needs regular check ups' and the lowest, 'a bath can be taken 1 month after stitches are removed'. 2. The total average score for learning needs was 60.78 and the mean item score was 3.04 as measured on a 4-point Likert scale. The item showing the highest learning need was 'electrical fields can affect the pacemaker's function and the lowest learning need was for sexual activity after permanent pacemaker implantation'. Conclusion: According to the above findings, it can be concluded that an intensive nursing education program should be developed for patients with a permanent pacemaker especially for those patients over 50 years of age and those with lower levels of education.
