This study focuses on looking at the influence of silhouette in the 1930s on fabric pattern design by comprehending how differently flower-pattern design were found according to clothing silhouette. The period scope of research was limited to 1930s, and the research object was set as the flower patterns seen in the designer's high-fashion and the women's daily apparel as well as the clothes for sports and leisure activities. Based on the above research scope, the researcher investigated the clothing silhouette and the textile patterns in 1930s by reviewing the literature about domestic and foreign books, research papers, domestic and foreign fashion magazines, information on the Internet. A glance at the women's clothing in the 1930s reveals that they emphasized something inactive, elegant, feminine and that great popularity was given to feminine silhouette that closely fitted the body and long and slim, as skirts became longer and longer. Like this, silhouette refused traditional methods in the technique of expressing flower patterns that were on-trend in that period, pursued the freedom of line and form, used shadowing technique by means of free pens and brushes and the effect of watercolors. It also arranged in a semitransparent way and painted contours alone, too. Flower patterns fell into two categories: amorphous abstract patterns and standardized abstract patterns. The patterns expressed themselves, divided into small-scale irregular patterns and abstract geometric patterns that filled the entire textile.

Factor analysis was applied to study the thermal decomposition of barium titanyl oxalate (BTO) which is used as the precursor of barium titanate. BTO was synthesized in $H_2O$ solvent and calcined at various temperatures. The X-ray diffraction patterns were obtained to make the data matrix of peak intensity vs. 2${\theta}$. Abstract factor analysis and target transformation factor analysis were applied to this data matrix. It has been found that the synthesized BTO consists of the crystals of $BaC_2O_4{\cdot}0.5H_2O\;and\;BaC_2O_4{\cdot}2H_2O$ as well as the amorphous solid of TiO-oxalate. The results also indicate that the BTO was transformed via $BaCO_3\;to\;BaTiO_3\;and\;Ba_2TiO_4$ during the thermal decomposition.
