The purpose of this study is to explore the meaning and depth of traditional knitwears, and to develop knitwear designs by using Aran motif, one of major motifs of traditional knitwears and on the basis of the 'continuance' theory of Henri Bergson and Jill Deleuze. Connectivity, the sense of space and deconstructive fluidity-basic concepts of the continuance theory-are felt in such forms as pleats, origami, and air pumping systems, blob and twisting used in the modem fashion. The motif of Aran knitwear which has a long historical tradition can be reinterpreted in terms of those concepts of the continuance theory. In this study, we designed five pieces of knitwear while applying cable motif, an important motif of Aran knitwear, and the concepts of the continuance theory to them. This study will make a contribution to the designing of knit wears through reinterpretation of a traditional motif in terms of a modem philosophical thought.

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.

N-nitrosamines are the nitroso compounds which are produced by nitrosation reactions of the secondary amine and nitrite under acidic conditions. Approximately 300 species of N-nitrosamine have been tested for carcinogenicity in laboratory experiments, with 90% of them demonstrated carcinogenic effects different animal species, including higher primates. In 1978, IARC classified NDMA and NDEA as Group 2A, and NDPA, NDBA, NPIP, NPYR and NMOR as Group 2B. In this study, we established pretreatment and analytical method for N-nitrosamines (NDMA, NDEA, NMEA, NDPA, NDBA, NPIP, NPYR and NMOR) in human urine for biological monitoring of N-nitrosamines. The analytes were extracted using solid phase extraction (SPE), then quantitative analysis was performed by LC-(APCI)-MS/MS. The accuracies of the established method were between 85.8~108.7% and precisions were lower than 20%. The limit of detection (LOD) were between 0.0002 (NDBA) and 0.0793 (NDMA) ng/ml. The linearity obtained was satisfying for the 8 N-nitrosamines, with a coefficient of determination ($r^2$) higher than 0.999. The mean concentrations of N-nitrosamines in the urine were 2.645 mg/g creatinine for NDMA, 0.067 mg/g creatinine for NDEA, 0.009 mg/g creatinine for NMEA, 0.011 mg/g creatinine for NDBA, 0.271 mg/g creatinine for NPIP and 0.413 mg/g creatinine for NPYR. NDPA and NMOR were not detected. It can be used as a instrumental methodology for evaluation and risk assessment of human exposure to N-nitrosamines for the further research.
