  • A pioneering version of an on-line management system for high-energy molecules (MS-HEMs) was developed by the ADD and BMDRC in Korea. The current system can manage the physicochemical and explosive properties of virtual and existing HEMs. The on-line MS-HEMs consist of three main routines: management, calculation, and search. The management routine contains a user-friendly interface to store and manage molecular structures and other properties of the new HEMs. The calculation routine automatically calculates a number of compositional and topological molecular descriptors when a new HEM is stored in the MS-HEMs. Physical properties, such as the heat of formation and density, can also be calculated using group additivity methods. In addition, the calculation routine for the impact sensitivity can be used to obtain the safety nature of new HEMs. The impact sensitivity was estimated in a knowledge-based manner using in-house neural network code. The search routine enables general users to find an exact HEM and its properties by sketching a 2D chemical structure, or to retrieve HEMs and their properties by giving a range of properties. These on-line MS-HEMs are expected be powerful tool for deriving novel promising HEMs.

  • In this paper we present an efficient technique for sketch-based 3D modeling using automatically extracted image features. Creating a 3D model often requires a drawing of irregular shapes composed of curved lines as a starting point but it is difficult to hand-draw such lines without introducing awkward bumps and edges along the lines. We propose an automatic alignment of a user's hand-drawn sketch lines to the contour lines of an image, facilitating a considerable level of ease with which the user can carelessly continue sketching while the system intelligently snaps the sketch lines to a background image contour, no longer requiring the strenuous effort and stress of trying to make a perfect line during the modeling task. This interactive technique seamlessly combines the efficiency and perception of the human user with the accuracy of computational power, applied to the domain of 3D modeling where the utmost precision of on-screen drawing has been one of the hurdles of the task hitherto considered a job requiring a highly skilled and careful manipulation by the user. We provide several examples to demonstrate the accuracy and efficiency of the method with which complex shapes were achieved easily and quickly in the interactive outline drawing task.

  • The purpose of this study was to understand the present condition about the space planning of the nursing rooms at the child care center in U.S.A. The researchers investigated the physical conditions of the centers through sketching, measurement, taking pictures and observation. On the other hand, to understand the user's needs, the interview to the directors of the centers was performed. As a result, the followings were proposed. The grouping of children depending upon the age has to be more classified according to the development period. And the guideline for the space areas has to be improved to a larger standard than present regulation. And the most impressive characteristic of the center in U.S.A. is the functional space design. The space such as toilet, washing room, kitchenet are well organized into the nursing rooms for children. Various ideas for arranging above functions in the small nursing rooms have to be developed in Korea. And the dynamic space arrangement of nursing room is also impressive. The material of the floor has to be considered variously for the comfort of the children.

  • Present expression methods have close relations with popular culture in the active acceptance of various kinds of genre. Fashion illustration is no longer limited to sketching garments or technically explaining construction, it is accepted as an art that is expressed by the desire and consciousness of the artist. This study examines the expressional characteristics and effects of photo-image appropriation as an expression method in fashion illustration. The word 'appropriation' (to steal something) is used as euphemism and not meant to be derogatory. The methods of appropriation in art indicate that paintings are not inventions but are self-satisfactory creations that show that the idea of originality is false and that paintings should be uninhibited from the greed of the authority of the genius of artists. In postmodern paintings, the photo-image of appropriation are expressed through the methods of re-photography, photo collage, and photo painting. Photo-image appropriation methods in fashion illustration are re-photography, photo collage, image mixing of photography, drawing, and graphic expression of photography. Fashion illustrators are able to develop expression techniques for expanding a field of expression and enhance the ability of communication through the photo-image appropriation methods.

  • In this paper, we present a leaf image retrieval system that represents and retrieves leaf images based on their shape. For more effective representation of leaf images, we improved an existing MPP algorithm. Also, in order to reduce the response time, we proposed a new dynamic matching algorithm at basically revises the Nearest Neighbor search. The system provides users with an interface for uploading query images or tools to generate queries based on shape features and retrieves images based on their similarity. For convenience, users are allowed to easily query images by sketching leaf shape or leaf arrangement on the web. In the experiment, we constructed an image database of Korean native plants and measured the system performance by counting the number of similar images retrieved for queries.

  • The purpose of this study is to analyze style and usage of furniture for rural house and to organize the changing process of the furniture. The data were collected from 32 residences in Samga 3-ri village in Youngin Kyungkido by field survey measuring and sketching the furniture were also performed as a supplement of investigation. Qualitative analysis were done by discriptive method. 1) It was found that the major furniture for rural household were storing furniture such as wardrobes, blanket chests, drawer chests, cupboards until 1976. The time when the supportive furniture such as sofa sets and dining sets were purchased on the rural area was after late 1970's. 2) The style of the furniture was investigated through the analysis of the size, material, structure, finishing and ornamentation. The changing process of style was from luxurious look to natural look. Therefore the storing furniture of the rural household showed a state of transition between traditional and modern style. 3) As a result of analyzing the place where the furniture were used, the cupboards showed to move from Marus (the living room area) to Buauks (the kitchens). The wardrobes were mainly used in An-Bangs(the master bedrooms) and Kuhnnun-Bangs(the room opposite the master bedrooms), but the style of those wardrobes were different each other.

  • The purpose of this study is to understand the physical accessibility of the child care centers for disabled children in Japan. Fifteen centers located in Tokyo, Japan were surveyed through sketching, measuring, taking pictures, and observation. To understand the user's needs. the directors of the centers were interviewed. As a result,the followings suggestions were proposed. First, when the entrance of the center is close to the road, careful design for the entrance area is required to secure the safety of children using wheelchairs. If possible, a fence or door between the corridor and entrance is necessary. Second, most aspects of accessibility are pretty well designed. But a canopy over the entrance area is required to escape the rain. Third, a wider corridor space is desirable for storing and driving wheelchairs and for special equipment for the disabled. Forth, because the emergency exits were installed but not used, the new and safer emergency exits should be installed. These results will be a good case reference for developing Korean design guidelines for the children with disabilities.

  • In order to develop specific genetic markers and determine the genetic diversity of Bangladeshi native cattle (Pabna, Red Chittagong) and exotic breeds (Sahiwal), randomly amplified polymorphic DNA (RAPD) analysis was performed using 12 primers. Genomic DNA was extracted from 20 cattle (local and exotic) blood samples and extracted DNA was observed by gel electrophoresis. Among the random primers three were matched and found to be polymorphic. Genetic relations between cattle's were determined by RAPD polymorphisms from a total of 66.67%. Statistical analysis of the data, estimating the genetic distances between cattle and sketching the cluster trees were estimated by using MEGA 5.05 software. Comparatively highest genetic distance (0.834) was found between RCC-82 and SL-623. The lowest genetic distance (0.031) was observed between M-1222 and M-5730. The genetic diversity of Red Chittagong and Sahiwal cattle was relatively higher for a prescribed breed. Adequate diversity in performance and adaptability can be exploited from the study results for actual improvement accruing to conservation and development of indigenous cattle resources.
