Abstract: This study focuses on a process of Value Engineering (VE) for Hanok, Korean traditional residence, and its major building components. The purpose of this study is to support designer or builders with objective clues for decision-making by VE, especially when a preliminary design needs changes and feedbacks for the next steps toward design development and/or construction processes. For this research, Hanok elements were reviewed first in overall, and six major components have been selected for performing VE analyses: wall, roof structure, Giwa that is Korean traditional roof tiles, openings, Ondol that is Korean traditional floor-heating system and fence system. The wall system among those was used for a target to be examined in this paper, because this element affects the value of Hanok mostly in aspects of function and cost. For this research, popular applications using Information and Communication Technologies (ICT) such as Green Building Studio (GBS) have been utilized for simulati

Abstract: Computer security is largely supported by passwords forming the principal part of the authentication process. Visual passwords have been proposed as a more secure alternative to alphanumeric passwords but have not as of yet been readily adapted due to the problems associated with current implementations of visual passwords. One of the main issues in the implementation of visual password schemes is the type of password images used. To address the issue of designing and using secure password images, we present a model of a shape grammar supported visual password scheme generating password images that adhere to a specific syntax or set of rules. We present a design of a grammar model which is well adaptable for implementations of visual password scheme images and images with a rule based structure.
