변화와 경쟁을 전제로 한 지식기반사회, 정보화사회에서는 창의성을 중요시하고 있다. 이러한 현상은 사회 전반에서 나타나고 있으며, 디자인 분야는 그 어느 때보다 창의적인 디자인 개발을 요구받고 있다. 디자이너가 창의적인 아이디어를 발상하고 그것을 더욱 더 창의적으로 발전시키는 데 도움을 줄 수 있는 디자인 사고기법에 관심을 두어야 하는 까닭도 여기에 있다. 이러한 배경에서 본 연구는 창의적인 시각디자인 개발을 위하여 아이디어를 발상하고 발전시키는 데 유용한 사고기법 중의 하나인 스캠퍼의 활용에 관하여 연구하였다. 2차에 걸친 설문조사를 바탕으로 시각디자인 과정에서 창의적 사고기법들과 스캠퍼의 활용 현황을 조사하여 그 결과를 바탕으로 스캠퍼의 활용 가능성을 살펴보았다. 연구 결과로 시각디자인 과정에서 스캠퍼를 효과적으로 활용할 수 있도록 아이디어 발상 및 발전 단계들에 맞추어 스캠퍼의 사고기술들을 분류하고 체계화하여 제시하였다.

Trompe-1’oeil technique strategically conceived with a view to effectively realize creative ideas among the expression techniques of fine arts style has provided the driving force in development of fine arts and has continuously influenced development of the modern fashion pursuing unique individuality. The purpose of this study is to open a new horizon for the development of fashion as a practical art, and to seek the expansion of the creative domain and ultimately to contribute to the creation of original and creative fashion by examining the interrelationship between Trompe-1’oeil, which has long been utilized and positioned as one of the leading fine arts techniques with the advent of surrealism in the beginning of the 20th century and the modern fashion. The study is focused first on finding out how Trompe-1’oeil technique originated in connection with researching the fashion of Trompe-1’oeil and on analysing the techniques of expression, and then on investigating into Elsa Schiaparelli, pioneer of Trompe-1’oeil technique to identify her influences, and finally on classifying clothes employing Trompe-1’oeil technique by their expression method to examine how Trompe-1’oeil technique has been applied to modern clothes. As for the research method, the researcher has referred to fine arts books, collection of pictorial records and the like to gain conceptual understanding of Trompe-1’oeil and to examine the expression method and the features of Trompe-1’oeil, and collected and referred to fashion books and fashion marazines to understand Elsa Schiaparelli and the expression tendencies of Tromprf-1’oeil in modern fashions. Particularly, the researcher has attempted to search the correlation between modern fashion and Trompe-1’oeil technique. As a result of this research, the researcher has managed to classify Trompe-1’oeil technique expressed in modern fashion into ‘harmony’, ‘application of the human body’, ‘front and back’, ‘surface and inside’. ‘completion of the incomplete’ and ‘detail.’ The researcher has also noted that Elsa Schiaparelli, a surrealist first applied Trompe-1’oeil technique to clothes and confirmed that quite a few avant-garde clothes designers following Elia Schiaparelli, by using Trompe-1’oeil technique in clothes, recently recreate fresh feelings.

The analysis of microarray data is essential for large amounts of gene expression data. In this review we focus on clustering techniques. The biological rationale for this approach is the fact that many co-expressed genes are co-regulated, and identifying co-expressed genes could aid in functional annotation of novel genes, de novo identification of transcription factor binding sites and elucidation of complex biological pathways. Co-expressed genes are usually identified in microarray experiments by clustering techniques. There are many such methods, and the results obtained even for the same datasets may vary considerably depending on the algorithms and metrics for dissimilarity measures used, as well as on user-selectable parameters such as desired number of clusters and initial values. Therefore, biologists who want to interpret microarray data should be aware of the weakness and strengths of the clustering methods used. In this review, we survey the basic principles of clustering of DNA microarray data from crisp clustering algorithms such as hierarchical clustering, K-means and self-organizing maps, to complex clustering algorithms like fuzzy clustering.

Streptomycetes are gram-positive filamentous bacteria that are well-known for producing a vast array of bioactive compounds, including more than 70 % of commercially important antibiotics. For the research about Streptomyces sp., the protoplast and electroporation transformation method have been the general techniques for the construction of transformants. However, these techniques have low efficiency and are time-consuming. Another option is intergenic conjugation, which is used for DNA transfer using methylation-deficient E. coli as a DNA donor to avoid the methylated-DNA-dependent restriction systems of actinomycetes. This conjugation method has been widely improved and applied to many other actinomycetes. In this research, an effective transformation procedure for the construction of expression vector by using gateway system was established to avoid limit of restriction enzyme site for cloning of target gene based on transconjugation by Escherichia coli ET12567/pUZ8002 with a pSET152 integration vector.

The mitochondrial genome encodes 13 proteins that are components of the oxidative phosphorylation system (OXPHOS), suggesting that precise regulation of these genes is crucial for maintaining OXPHOS functions, including ATP production, calcium buffering, cell signaling, ROS production, and apoptosis. Furthermore, heteroplasmy or mis-regulation of gene expression in mitochondria frequently is associated with human mitochondrial diseases. Thus, various approaches have been developed to investigate the roles of genes encoded by the mitochondrial genome. In this review, we will discuss a wide range of techniques available for investigating the mitochondrial genome, mitochondrial transcription, and mitochondrial translation, which provide a useful guide to understanding mitochondrial gene expression.

Presents age is diversified in all genres by fast development of information and digital, and expression of fixing is not. Architecture and interior space design is showing new paradigm through dematerializing, ex-formal, nonlinear. Glass material is expressing by various technique in space and outer skin to introduction of digital media and a high-tech technology. Expressive characteristics and Techniques of this glass material are showing form of homogenized life in this age, simulated life. Therefore, this study does theoretical investigation through dematerializing of glass material, and analyzes works after 2000. Wish to understand stream of indoor design of present age after analyzes expression special quality and technique of glass material that reflect age and make a study of symbolic expression characteristic.

This study examined the history of nail art in 20th century, defined characteristics of many techniques used on nails, and analyzed how those techniques have been utilized in recent nail art works. For the method of the study, books and previous studies on nail art were examined as primary sources, and newspaper articles on nail art were studied as references. Then, the case studies were conducted on photographs of nail art works published in Nail Holic in 2012. As a result of analyzing expression techniques of nail art featured on Nail Holic, there had been a total of 517 works created using a single technique. The reason why hand painting is used very frequently is because artists can draw unique images of their own to create various designs according to their tastes. Rhine stone is also very popular, because stones are easy to apply and various in their shapes and colors. There were a total of 555 works created using two or more techniques. The most important point to examine is that hand painting, rhine stone, and 3D art were most popular among all techniques. These works featured highly various effects and images by combining flat effect of hand painting with three-dimensional effects of rhine stone or 3D art. The tendency can also be found in the fact that there have been many works using techniques of flat effects such as decal or marbling combined with techniques of three-dimensional effects such as rhine stone or 3D art.

연구의 목적은 자연의 소중함을 깨닫게 된 코로나 시대를 거치면서 자연의 다양한 모티브 중에서 개체 수의감소가 환경오염의 척도로 상징되는 나비, 곤충 등의 표현 빈도가 증가하는 것에 주목하고자 하였다. 본 연구의 범위는 2019년부터 2023년까지의 패션컬렉션을 대상으로 온라인 <보그>지(www.vogue.com)의 시즌별 패션컬렉션 패션쇼 사진과 인터뷰 기사로 한정하였다. 연구 결과 185개의 나비모티브 의상이 나타났으며 평면적 표현방식의 유형으로는 디지털 프린팅 기법이 가장 많이 활용되었다. 이와 함께 퀼팅, 자수, 비딩 등의 기법들이 나비의 평면적 모티브를 표현하는 기법으로 많이 등장하였다. 입체적 표현 유형으로는 3D 프린팅, 레이저 컷팅, 코사지 기법, 드레이핑 기법을 사용한 유형들이 비슷한 비중으로 나타났다. 표현된 나비 모티브는 추상적인 표현보다는 나비의 형태를 그대로 묘사한 사실적인 디자인이 더 많았음을 알 수 있었다. 결론적으로 최근 5년간의 나비모티브 패션디자인은 과거의 나비모티브 패션에 비해 환경에 대한 메시지를 강하게 담고 있음을 알 수 있었다. 단순히 나비의 형태적 아름다움과 화려한 디자인 요소를 넘어서 친환경 메시지를 전달할 수 있는 상징적 의미가 큰 모티브임을 확인할 수 있었다.
