새롭게 발견되는 단백질의 구조와 기능 예측에 사용되는 모티프는 단백질 원시 데이터가 빠르게 증가함에 따라 그 중요성 역시 나날이 증가하고 있으며 이러한 모티프에 대한 다양한 서열 메소드들과 데이터베이스들이 개발되었다. 그러나, 이러한 모티프 데이터베이스들은 각각 이질적인 데이터 구조를 지니고 독자적으로 개발, 개발되어 왔기 때문에 서로 다른 형태의 검색 결과를 제공한다. 따라서 사용자는 각 데이터베이스에서 사용하는 데이터 구조들에 대한 전반적인 지식을 습득해야 하며 모티프 데이터베이스들 각각에 대해 중복된 반복 검색 작업들을 수행하여야 한다. 따라서 이 논문에서는 이러한 문제 해결을 위해, 각각의 모티프 데이터베이스들에서 제공하는 자원을 분해하고, 합병하는 과정을 거쳐 하나의 통합된 모티프 데이터베이스를 구축하였고, 기존의 데이터베이스에서 지원하지 못했던 단백질 3차 구조정보, 분류 정보의 지원을 가능케 하였고, 각 멤버 데이터베이스 검색 메소드의 장점을 그대로 적용할 수 있는 메타 엔진을 설계하여 사용자 편의적 검색 환경을 제공한다.

An integrated environment for optimum design has been developed using Motif. The integrated environment is composed of the preprocessor, the postprocessor and the optimization part. The preprocessor is part of making a finite element model for optimum structural design and the postprocessor displays results of optimum design and the optimization part is the part which execute optimization. It is designed to reduce user's difficulties in structural optimum design. It used Graphic User Interface for the concurrent representation of various inputs and outputs through the dialog box, mouse and keyboard. Structural optimum design can be done easily through dialog box, menu, concurrent representation of modeling process and results of structural optimum design can be understood easily through stress contour, deformed model and graph of cost function.

Rapid development of life sciences about human cloning in real world is reflected alternately ahead and behind in the movies and it brings up the conversation topics about the scenario of diverse human life in the near future. This study is the consideration of the characteristic of the human cloning motif in movies, focused on the feature film which consider human cloning a philosophical point of view. The emergence and evolution of somatic cell cloning conclude the problem of philosophical anthropology. And identity and un-naturality of human clone boils down to desire and dilemma of character in . The dramatize to the exclusion of genre's attribution and the setting of twofold relationship between original and clone as well as real mother and daughter prove the critical mind of as stated above. This study also reported it reinforces the characteristic of the human cloning motif in movies that plotting with parallel narrative and the consistent attitudes with various cinematic expression and techniques.

This study identified the scenic characteristics in Gugok and symbolism reflected in titles of the scenery of the season in Gugok from a perspective of Sundoism concentrated on Galeun Gugok in Goisan which is influenced most greatly by Sundoism hermit ideas in Korea, along with Seonyudong-Gugok. In addition, it suggested a measure for arrangement and narrative Storyboard of Galeun Gugok structure corresponding with promotion and propagation of Gugok cultural scenes and educational goals. According to analysis and interpretation of the various Gugoks forming Galeun Gugok in terms of their titles, names engraved in surrounding elements and the coherent symbolic meanings of its scenery and place through comparison with secenery of near Seonyudong-Gugok, the result shows that Galeun Gugok comprises wishes for eternal life in the forms of Taoist hermit-related scenery of the season within the range of stream and old stories based on environmental affordance. In figurative way, it ultimately presents the Wonyung(圓融) idea which seeks a harmonious combination of God and humankind. In particular, consciousness of longevity without problems is deeply inherent in the background of eternalness of plants, divinity of animals and natural homeostasis. Also, 9 Gok Seongukam set up at visual terminal reflect noticeably that a game Go is the amusement of the immortals, which describe 9 ranks of GO figuratively. Galeun Gugok is formed in a unity structure, which is hermit-oriented Sundoism and motif, such as longevity and immortality, divinity and enjoyment of Sundoism hermit rather than used as a method to achieve taste for the arts or ethics. Given the fact, it presents eternal longevity and atmosphere of seclusion in very strong way. Development of spatial Storyboard structure based on this is interpreted as 'Entering the world of hermits(Introduction)'-'Looking the world(Development)'-'Living with hermits(Turn)'-'Becoming hermit(Conclusion).' Finally, the scenery image of Galeun Gugok presented in surface structure is based on beauty of the immortal land scenery as well as beauty of pre-achieved space in Gugokdongcheon and arranged the vertical narrative structure as divine space of 9 ranks of GO. Taking those into account, scenery story board of Galeun Gugok was suggested in accordance with a theme of 6 cuts; Gnagsun(降仙)-Sungyeong(仙境)- Sunyak(仙藥)-Sunhak(仙鶴)-Sunyu(仙遊)-Eunsun(隱仙). It is obvious that hermit which live an eternal life as a representative of Sundoism, should be the main motif of scenery planning in a filed of modem landscaping. Therefore, the most valuable component in designing Korean landscape must be the homeostasis of surrounding landscape which supports the characteristics of invariability and divinity of nature.

Protein structure is highly related to its function and comparing protein structure is very important to identify structural motif, family and their function. In this paper, we construct an integrated database system which has all the protein structure data and their literature. The structure queries from the web interface are compared with the target structures in database, and the results are shown to the user for future analysis. To constructs this system, we analyze the Flat-File of Protein Data Bank. Then we select the necessary structure data and store as a new formatted data. The literature data related to these structures are stored in a relational database to query the my kinds of data easily In our structure comparison system, the structure of matched pattern and RMSD valure are calculated, then they are showed to the user with their relational documentation data. This system provides the more quick comparison and nice analyzing environment.

Creativity is crucial in designing and producing attractive accessaries and daily supplies as well as art works. Generative design can be a paradigm to be used to obtain novel ideas or motifs for creative design works. This paper introduces a generative design method which comes up with unique ring models using genetic algorithm. It presents how the genetic algorithm works in terms of candidate solution coding, operators, and fitness evaluation function. The proposed method allows the customers to express their personal preference and later the preference to be reflected in fitness evaluation. In the final stage of the proposed method, several ring models are suggested for customers to choose on their own. The chosen ring models can be put into physical rings with the help of a 3D printer because the models are expressed in 3D geometric structures.

The outer membrane of Gram-negative bacteria is the outermost layer of cellular environment in which numerous biophysical and biochemical processes are in action sustaining viability. Advances in cell engineering enable modification of bacterial genetic information that subsequently alters membrane physiology to adapt bacteria to specific purposes. Surface display of a functional molecule on the outer membranes is one of strategies that directs host cells to respond to a specific extracellular matter or stimulus. While intracellular expression of a functional peptide or protein fused to a membrane-anchoring motif is commonly practiced for surface display, the method is not readily applicable to exogenous or large proteins inexpressible in bacteria. Chemical conjugation at reactive groups naturally occurring on the membrane might be an alternative, but often compromises fitness due to non-specific modification of essential components. Herein, we demonstrated two distinct approaches that enable site-specific decoration of the outer membrane with a fluorescent agent in Escherichia coli. An unnatural amino acid genetically incorporated in a surface-exposed peptide could act as a chemoselective handle for bioorthogonal dye labeling. A surface-displayed α-helical domain originating from a part of a selected heterodimeric coiled-coil complex could recruit and anchor a green fluorescent protein tagged with a complementary α-helical domain to the membrane surface in a site- and hetero-specific manner. These methods hold a promise as on-demand tools to confer new functionalities on the bacterial membranes.
