The construction industry consists of various and massive architectural information as an architectural process includes a variety of design stages with cooperation of many disciplines. Particularly, architectural information is generated and managed through the life cycle of a building, from conceptual design stage to the construction and maintenance. A Building Information Model (BIM) serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle from inception onward. BIM technology accomplished quantitative development being utilized in various disciplines. However, it is necessary to develop environment and requirement for qualitative improvement of BIM based project. Particularly, requirement is very important for architectural design evaluations. The purpose of this study is to develop and apply of quality control requirement for improving the quality of architectural design in open BIM environments. To achieve this purpose, the authors have investigated case study for open BIM data quality control (software, guideline and application case) and classified quality control targets according to physical/logical quality and data quality. In addition, the authors have defined open BIM based quality control process and developed quality control requirements. Finally, the authors have developed rule based quality check system using requirements for efficient quality control based on open BIM.

Design for improved usability is to understand products from the user's point of view so eventually to enhance the pleasantness users by reflecting it into the design. The philosophy of user-oriented design is an essence of human-centered product planning, and its application is more important for railway vehicle design, which is closely connected with everyday life. This study focused to define basic elements of train interior design concept, which considers convenience and comfort for passengers, by extracting and interpreting ergonomic requirements, as usability factors, of train toilet design. The study on user-oriented design of trains consists of the practice of sensibility engineering for the management of customers' emotions and its harmonious use on design, and aims on the embodiment of new ergonomic design. In the center, it has analyzed the criteria and characteristics of the user-oriented design and has concluded the design direction and components to a concrete idea and proposed prototypes, which may become a good example for train interior design later on. In addition, it proposes a direction, which may become a guideline of ergonomic design, to secure competition capacity. Moreover this study is concentrated on the physical environment and human behavior of train toilet users, on the analysis of factors necessary for adequate toilet design, and on the understanding of interface between its users. What is more, it proposes a module of development process and methods of approaching the interface. The study presents a design standard, under which the concrete data of the characteristics and practicable range and the convergent demands accelerate to the module could be confirmed and criticized. The study on the usability is going to contribute to more pleasant and comfortable train environments and consequently, it's going to create new values of increased railway competitiveness by design.

Electronic commerce in digital environment is greatly different from the commerce in physical environment in the past (reality environment) in terms of marketing, distribution structure and, above an, comsumers'purchase pattern. The Old purchase pattern is that a consumer buys a product after s/he touches, tests, and feels it physically, while the purchase pattern in electronic commerce enables the comsumer to make a decision about whether to buy it or not through the information gleaned from the computer monitor screen. A number of products which appears in the market now are designed to use the reality environment setup without consideration of the digital environment, of which the intention is to appeal to consumers with a series of design process. However, taking under consideration the present situation in which lots of electronic commerce are made in the cyber space or digital environment, we are required to forward the product design which can gains the positive attraction for consumers in this environment. Factor analysis is made in order to understand how the subjects perceive the image of the design of the product both in reality situation and in digital environment. The result shows the first factor has different images in those environments. In the background of this conclusion rests the fact that the difference of the transfer of formative factors to consumers is made in the images which show themselves in those different environments.

Universal Design is comprised of three main concepts known as barrier-free, adaptive and life-span design. It does not focus on accessibility for the disabled, but rather expands its breadth to the comfortable use and easy access in ail physical environments and facilities. In this study, the researcher views the present and future of universal design through the cases of kitchen design. Based on the market changes in design guidelines and the changes of time uncovered from past studies, this researcher suggests that universal design would develop through mass customization for personalized use, application of new technology and consideration of psychological aspects. Additionally, for the diffusion of universal design appropriate solution in economic cost problem, social recognition and conversion of problem cognizance in designing is needed. In Korea design models of universal design concepts are not yet in production over various fields. In order to develop and study universal design which suits our country, cultural and regional characteristics should be considered as well as physical, perceptual, psychological aspects.

The depth, width and alignment of fairway that are main port water facilities should be designed considering the various elements including particulars of design ships, weather and sea conditions around fairway and method of ship-handling. However not only the existing Japanese design standard for fairway and also those of other countries do not take into consideration of such kind of elements and no design standard is made by quantitative analysis. In this circumstance the new design standard (Approach Channels, A Guide for Design) depending on classified various elements and quantitative analysis was proposed in 1997 by PIANC and IAPH. But it was proved that calculated values according to this standard were unfounded and had some problems to output the discontinuous value by small difference of calculation condition because the each value fur each element was simply added. And also it is hard to apply this standard to the design of port water facilities in Japan because this [A Guide for Design] is the design standard for long channels in European port. The proposal of more reasonable Japanese standard will be expected by applying the study result of naval architecture and navigation and by the cooperation of ship operators to use fairway, naval architects to built ships and civil engineers to dredge fairway. The concept of a fairway in 'Design standard fur fairway in next generation' is defined as passage for approach channel) and traffic lane designated by light buoys as navigable water for safe navigation. In 'Design standard for fairway in next generation' depth, width and alignment are picked up among many design elements of a fairway. Design method for those elements is shown based on design ships and navigational environments. This standard shows the method of design for each dimension depending on characteristic on design ship and weather and sea condition. On the other hand, in case of existing fairway, it is possible to decide the size of ship and navigation criteria by opposite analysis.

In this paper, we present a new cぉnet coding method, so called MLC (Multi-Level Codes), for error detection and correction in digital wireless communication. MLC coding method we the same coding procedure wed in the convolutional coding but it is distinguished from the existing convolutional coding in point of generating the code word by using multi-level information data (M-ary signal) and in point of speed of coding procedure Through computer simulation, we analyze the performance of the coding method suggested here compared to convolutional coding method in case of modulo-operation and in case of non-binary coding Procedure respectively under various channel environments.
