This study was carried to establish a new landscape-oriented gardening model based on climate, vegetation, and forest landscape characteristics. In addition, innovative forest garden models were suggested through an integrated approach to the ecological characteristics of forest vegetation communities and existing garden planting types. For the study, the key landscape elements that make up the main forest vegetation community were identified. And the vertical layers and horizontal distribution patterns of the community structure were typified by diagnostic species and their growth forms & habits such as dominant species, character species, and differential species, and degree of dominance-sociability. Based on this, a standardized vegetation structure and formation was developed by stratifying the landscape into main features, minor features, and detailed features according to visual dominant elements. Also, the applicability of the forest garden model was examined by applying the concept of borrowing landscape to representative deciduous broadleaf forests in the temperate northern region of Korea. Additionally, an integrated forest garden models based on the conceptual definition and typology of forest gardens, and a strategic approach to forest vegetation were proposed

This study observes information education of facilities for the disabled. A certain facility for the disabled was selected in Daejeon to compare the educational environment for visually disabled of regular school for visually disabled and facilities for the disabled, and then personnel current situation by age and form of the disabled, teacher current situation by age, computer possessing current situation, weekly education schedule for the disabled, and equipment possessing current situation for visually disabled were observed. As a result, expansion of Braille education was necessary for the Braille skilled, which is the basis of information education information to visually disabled is insufficient, and forming of learning environment was desperate since equipment necessary for computer education was absurdly lacking unlike regular schools. Also, only 10 out of 21 teachers(47%) majored in social welfare or special education, and none majored in computer. It is because support for employment of those who majored social welfare, special education, and computer is insufficient compared to treatment for teachers at general schools at the facility for the disabled since teacher employment regulation at the facility for the disabled is not set. It is studied that providing high-quality of education environment to the disabled was desperate through physical and social treatment that suits nurturing of the professionally knowledge personnel through expansion of equipments and constant education and training based on government support to promote information education of the facility for the disabled.

In this paper, we introduce a method to synthesize realistic make-up effects on input images efficiently. In particular, we focus on shading on the make-up effects due to the lighting and face curvature. By doing this, we can synthesize a wider range of effects realistically than the previous methods. To do this, the information about lighting information together with the normal vectors on all pixels over the face region in the input image. Since the previous methods that compute lighting information and normal vectors require relatively heavy computation cost, we introduce an approach to approximate lighting information using cascade pose regression process and normal vectors by transforming, rendering, and warping a standard 3D face model. The proposed method consumes much less computation time than the previous methods. In our experiment, we show the proposed approximation technique can produce naturally looking virtual make-up effects.

Information visualization plays an important role to provide a conceptual comprehension of the information and should be adjusted and featured to reflect the characteristics of the domain to which it is applied. Product searching in e-Commerce is not an exception. In this paper, we present visualization techniques that are specified for effectively browsing the results of product searching. We considered visualization techniques including MapNet and Cluster Map and modified them to reflect the characteristics of the product domain. We consider two types of search queries: category searching and product property searching, and make it possible to include more detailed product semantics in their search criteria. We also provide a query refinement mechanism so that even users with rack of understanding the products may rewrite their queries for better results.

Owing to the complexity of shapes and elements, some difficulties are found in the modeling and sharing phases in a project at the earlier design stages. This paper extends the boundaries by suggesting the data interoperability between 3D modeling software, McNeel Rhino 3D and BIM system, and Autodesk® Revit® Architecture. The main research methodology is to link the architectural form data in the NURBS supporting the 3DM format, especially for integrating surface properties into the mass family template of Revit. This algorithm-driven interoperability approach using visual programming, such as Dynamo in conjunction with Autodesk®, can be applicable in a theoretical part and also a practical use-case. This paper summarizes these results as sequence guidelines and project template recommendations suggesting an efficient design process to interoperate geometric data with the BIM system to manipulate and control the regular and curved form of office buildings.

Visual perception is part of a field of study that examines the analysis and recognition of objects. There have been numerous studies on this topic, including research on the physiological and cognitive aspects of the visual system. Visual perception theory was established through such research efforts and the potential for its application in each field is being investigated. Mobile displays are a representative example of media in the new age. Therefore, this study is based on the understanding that research on visual perception must stress the importance of useful visual cognition. This study used displays to conduct legibility tests based on illumination intensity and contrast ratio. Two conditions relevant to legibility were tested 1) illumination intensity environment and 2) two luminance conditions proposed as measures to improve readability in existing mobile displays. The results of this study were analysed to determine the degree of legibility based on illumination intensity and contrast ratio, and measures for improving legibility were proposed.
