To understand molecular and cellular mechanisms of many gene products in the female reproductive organs including the ovary and uterine endometrium as well as during embryo development, researchers have developed and utilized many effective methodologies to analyze gene expression in cells, tissues and animals over the last several decades. For example, blotting techniques have helped to understand molecular functions at DNA, RNA and protein levels, and the reverse transcription-polymerase chain reaction (RT-PCR) method has been widely used in gene expression analysis. However, some conventional methods are not sufficient to understand regulation and function of genes expressed in very complex patterns in many organs. Thus, it is required to adopt more high-throughput and reliable techniques. Here, we describe several techniques used widely recently to analyze gene expression, including annealing control based-PCR, differential display-PCR, expressed sequence tag, suppression subtractive hybridization and microarray techniques. Use of these techniques will help to analyze expression pattern of many genes from small scale to large scale and to compare expression patterns of genes in one sample to another. In this review, we described principles of these methodologies and summarized examples of comparative analysis of gene expression in female reproductive organs with help of those methodologies.

Fine art production methods are frequently incorporated into animation production. The Printing Expression method is often employed among fine art production. There are three main techniques in Printing Expression: Silk Screen, Woodcut and Etching. Animations that use Silk Screen and Woodcut techniques are quite common. However, it is rare to find Etching techniques in animations. So with that being said, I would like to introduce etching animation through the work of Piotr Dumala; the well known Ink Etched film director. Also, I analyzed the characters: movement, unique texture and sensuous feeling; that only mezzotinted Etched-Animation expression technique can show. If we can expand methods on how to show our imagination through etching techniques, it can allow many directors to produce etched animation films in which they can express their imagination.

The interlacing technique has a long history of use as a means of creative expression and persists in modern society to satisfy the individual pursuit of pastimes. This method has the developmental potential to create new trends in the future. Interlacing techniques (e.g., basketry, plaiting, braiding, and knotting) are closely related to plastic arts fields, architecture, art, and industrial design where the various interlacing practices are applied. This research uses case analysis to study the types of expression found in the formative art field wherein the interlacing technique is applied. Results reveal several expressions, including optical illusion visual type, relief surface type, porous perspective type, and object borrowing type, all of which appeared in fashion bags. The aesthetic formativeness, which appeared in the fashion bags that applied interlacing techniques, was then classified according to geometric formative beauty in a process based on rules and order. Nature-friendly formative beauty reflecting handicraft locality and omnidirectional formative beauty by disordered deconstruction and heterogeneous combination were determined. The use of interlacing techniques that show creative, unique combinations and variations is expected to inspire the development and application of bag design that suits individual and original modern fashion trends. One limitation of this thesis is that it only studied cases appearing in modern fashion bags.

The purpose of this study was to grasp the utilization of traditional Korean Patterns used for fashion cultural products. To achieve this purpose, this study examined the range of fashion cultural products through literature review, previous researches, and market surveys and analyzed the situation of fashion cultural products and the kinds, expression methods, expression techniques, and repeat styles of utilized patterns. The analysis results are as follows. First, in the use of traditional pattern, the most frequently-used fashion cultural products were small and inexpensive accessories, followed by fashion apparel, miscellaneous goods, and living cultural goods. Second, the most frequently-used traditional patterns were plant patterns, especially flower patterns. The next frequently-used ones were mixed patterns, especially in the mixture of flower and letter patterns, and $cloisonn\'{e}$ and flower patterns. The next frequently-used traditional patterns were animal patterns(especially butterfly patterns), followed by geometric patterns, lucky omen patterns, and letter patterns. In the expression methods of used patterns, most products except handicrafts preferred simplified patterns to real patterns. Finally, in the expression techniques of traditional patterns, the most frequently used technique was traditional embroidery, followed by the use of weaving fabrics such as fine gauze and brocade which are used for Hanbok. Also, transfer dyeing which is one of printing techniques, DTP(digital textiles printing), a mixed technique which adds embroidery to weaving fabrics, hand-painting, and a gilt technique were used. The results of this study suggest that most fashion cultural products except few designers' works attached weight to some specified patterns and expression techniques regardless of the characteristics of products since there is little understanding of a variety of patterns and are few researches and development on expression techniques.

Several clustering algorithms to analyze gene expression data and cluster validation techniques that assess the quality of their outcomes, have been suggested, but evaluations of these cluster validation techniques have seldom been implemented. In this paper we compared various cluster validity indices for simulation data and real genomic data, and found that Dunn's index is more effective and robust through small simulations and with real gene expression data.

This study examined the kinds, expression, techniques and arrangement of patterns for the traditional women's costume from 1995 to 2002 in North Korea. And the results were compared with South Korean. Conclusions are as follows : In the kinds of patterns the natural plant patterns were much more frequently used in North Korea. These tendency was same to South Korea. And the geometric patterns were more frequently used in South Korea. According to frequency in the expression of patterns, it was the realistic, geometric, stylized shape in North Korea. To the contrary it was the stylized, geometric, realistic shape in South Korea. In terms of decorative techniques, not only the traditional embroidery, gold leaf, multicolored stripes, but also modern collages, painting, beads, applique, flounce, ruffle were used in North Korea. Modern techniques were found comparatively a lot in North Korea, traditional techniques were found comparatively a lot in South Korea. In terms of arrangement of patterns, the modern arrangement was much more frequently used. And localized type of modern arrangement was found comparatively a lot in South and North Korea. Therefore traditional beauty was generally expressed by natural patterns, realistic shape and modern beauty was generally expressed by modern techniques and arrangement of patterns in North Korea.

This study considers expression techniques and aesthetic values in the images of head dress reflected in a natural motif. The conclusions of the study are as follows. The first type is the realistic expression (52.4%) such as the reproduction of a natural object's essential form (27.0%), the partial derivation of the natural object (19.3%), and the planarization for the actual image of the natural object (6.1%). The second type is a metaphorical expression (39.0%) which emphasizes the morphological characteristics of nature (18.2%), the structuration of the natural object's silhouette into a three-dimensional or two-dimensional form (11.5%), and the abstract expression of the form in the natural object (9.3%). The third type is a hybrid expression (8.6%) that is a compromise between practical (or metaphorical expressions) so that expression techniques represent a compromise between the natural object's essential form and abstract expression (4.6%) or the combination of the natural object's silhouette into a three-dimensional or a two-dimensional visualization (4.0%). Aesthetic head dress values reflected in the natural motif first indicate a primitive value. This state of natural instinct recreates the natural object or combines part of the biological elements of the natural object to create an inducement to escape from the practical world. The second is amusement in the expression of animals in dynamic and humorous forms creates an illusion of animals being alive with a representative playful enjoyment. The third is abstraction that grant freedom in the observer's aesthetic rational through a reinterpretation of the fashion designer. The fourth is eclecticism where a compromise represents an act of mixing a variety of independent factors to create harmony with the imagery of nature created through the grafting of diverse expression techniques that break away from stereotypes of existing natural objects to create a type of nature that cultivates new values.

The purpose of this study was to develop contemporary Qipao design that emphasized creative feminine beauty with a unique sense beyond the concept of traditional Qipao design. This would be achieved using the expressive technique of human liberation from the oppression of the unconscious world a supported by surrealism. Using existing literature and previous research, surrealist expression technique used in fashion were investigated and analyzed. The results are as follows. First, the possibility of new and original design beyond existing surrealistic Qipao design was demonstrated through various realistic surrealism expression techniques, such as dépaysement, objet, and trompe-l'œil techniques. This occurred by exploring various unconscious world out of fixed ideas and through expression techniques of surrealistic fashion such as imagery of body parts, metaphorical expression of objects, and position deformation and illusion. Second, Qipao design that combined objet and attempted ordinary escape by combining isolated body parts (such as hands, eyes, and lips) within the composition combine with surrealistic expression enabled various and fun surrealistic fashion designs to emerge. Third, the metaphor of surreal lips and eyes (mainly used in works of this study) presented a unique and extraordinary combination of images in accessories and partial design that used the dépaysement technique. Thus, it was possible to expand surrealistic expression by including LED wire.

Handbags are a part of fashion and while their significance and value are increasing, research on this topic is lacking. This study defines handbags and categorizes the materials used for making handbags, sewing methods, expression techniques, and terminologies related to accessories. A total of 1,743 handbags that were released from the Spring 2020 to Fall 2023, Ready-to-Wear collections by 8 selected brands (Hermes, Dior, Fendi, Chanel, Louis Vuitton, Prada, Gucci, and Alexander McQueen), were analyzed. Out of these, 732 unique designs, excluding those with only color variations, were studied. The most common sewing methods were 'Cut, sewing, and edge painting', 'Cylinder arm sewing', 'Cut, edge painting, and sewing', and 'Inverted seam', in that order. Slim strap designs primarily used the 'Cut, sewing, and edge painting' method, whereas the body, especially with narrow and hard leather, was best suited for the 'Cylinder arm sewing machine'. For expression techniques, the most frequently used methods were 'Quilting', 'Metal Eyelet', 'Embossing', 'Printing', 'Punching', and 'Weaving', respectively. The characteristics of each brand's production methods, expression techniques, and accessories were as follows: First, the exposure of logos and monograms is prominent. Unlike clothing, handbags often prominently feature the brand's logo or monogram. Second, signature quilting is a prominent feature. Quilting effectively conveys the brand's signature style, providing cushioning, volume, and pattern effects. Third, sustainable development is a growing trend. Brands are increasingly applying eco-friendly and socially responsible designs.

The human face has "expression" as an important visual factor in contrast with general objects. For this reason, cartoonists draw shadow that emphasizes facial shape and facial expression in order to convey atmosphere of scene and trait of character. This shadow should be considered when doing cartoon rendering for facial expression although it is not an physical shading. This paper proposes a cartoon rendering system for facial expression based on shading techniques of real cartoonist. First of all, we searched such techniques of cartoonist through variety of collected cartoon images and defined shadow templates according to character's facial expression to do cartoon rendering diffently. After that, we demonstrated cartoon rendering system of facial expression on the basis of survey result that effectively emphasizes facial shape and facial expression. Finally, we showed the usefulness through the user questionnaire.
